Modular furniture assembly

RELATED APPLICATIONS

This application is a partial continuation of U.S. patent application serial No. 11/149,913, "modular furniture assembly", filed on 10.6.2005, which is hereby incorporated by reference in its entirety.

Technical Field

The invention relates to the field of furniture. More particularly, the present invention relates to modular furniture assemblies.

Background

A large number of pieces of furniture having various shapes and sizes have been introduced in recent years in order to provide comfort and decoration. Consumers prefer furniture that can serve multiple purposes and resist wear from everyday use without much care. Accordingly, furniture that is versatile, durable, and requires relatively little maintenance is desirable.

Once purchased, the user desires that the furniture be assembled or that the furniture be easily assembled. However, once assembled, most furniture cannot be easily disassembled. Many pieces of furniture are assembled using nails, hooks, epoxy glue or some other type of fastener. In addition, various types of furniture have upholstery that covers the fasteners, making the furniture difficult to remove. This presents challenges to the user, especially when furniture needs to be transported from one location to another.

In addition, once assembled, users prefer furniture that can be easily cleaned. Many upholsteries are fastened to furniture by the use of nails and/or hooks, making it difficult to remove and clean when soiled or stained.

One aspect that makes furniture costly is shipping and packaging. For example, a large number of pieces of furniture require a large amount of space in transit. The non-solid shape of most furniture makes it difficult to maximize space utilization when packaging and shipping the furniture. Whether the furniture fills all or most of the required space, the furniture takes up a lot of space, thus increasing the cost of transportation.

Another aspect that makes the furniture expensive is the difficulty in stacking the furniture. When stacking a large number of pieces of furniture, the pieces of furniture stacked lowermost are most susceptible to frequent damage. This damage comes from the shape and non-solid nature of the packaged furniture. Even when the furniture is disassembled and boxed for stacking, there is often still much space wasted. Wasted space not only increases shipping costs, but also provides an unstable base for stacking other pieces of furniture.

It is desirable for users who cannot afford many pieces of furniture to have furniture that can provide multiple functions. For example, a Japanese bed serves as both a bed and a sleep chair. However, the Japanese bed is too large and is therefore limited by the cost factors mentioned above. In addition, japanese bed mattresses are often thin and are less comfortable to use either as a couch or a bed.

Disclosure of Invention

The present invention relates to modular furniture assemblies that can be quickly and efficiently assembled, disassembled, rearranged, moved, and cleaned with minimal effort. In one exemplary embodiment, a modular furniture assembly includes a base, at least one cross-member, and a coupler configured to facilitate removably coupling the cross-member to the base to form a furniture assembly.

In one exemplary embodiment, the base serves as a support surface on which a user may sit, while the cross member serves as a resting surface for the back or arms of the user. The coupler is configured to enable a user to quickly couple and decouple the cross member and the base with minimal effort and without the use of tools. The ease of coupling the cross member to the base enables a user to easily form furniture assemblies of various configurations.

The base is configured to be positionable adjacent to and removably attachable to the cross member in a variety of ways to provide a variety of configurations of modular furniture assemblies. In this manner, a variety of different furniture assemblies may be formed using a plurality of bases and cross members. For example, one embodiment uses one base and one cross member coupled together with the base to form a chair. In another embodiment, three cross members are coupled to one base to form an armchair. Also, the base and cross members may be placed at a variety of different locations to form a variety of different chairs.

In one embodiment, the base and cross member are sized and configured in a defined spatial relationship. For example, in one such embodiment, the length (x) of the base is substantially equal to the length (x') of the cross member, and the length (x) of the base is substantially equal to the sum of the width (y) of the base and the width (z) of the cross member. Thus, x is substantially equal to y + z. This relationship allows for the convenient formation of a variety of different types, sizes and configurations of furniture assemblies.

In use, one or more bases having a substantially similar configuration and one or more transverse members having a substantially similar configuration may be used together. The standardized configuration of the base and cross members enables a user to form a variety of different types and configurations of furniture assemblies. This also facilitates manufacturing, as a manufacturer can produce a series of bases having substantially similar configurations and a series of cross members having substantially similar configurations, and then arrange (or allow an end user to arrange) these bases and cross members into a variety of configurations to form different types of furniture. A user may purchase one or more bases having the same configuration and one or more cross members having the same configuration and then combine them to form a large number of different furniture assemblies.

For example, a chair having a backrest may be formed using a first base and a first cross member. Second and third cross members having substantially similar configurations as the first cross member may be added to form an armchair. Alternatively, the following may be added: (i) a second base having a substantially similar configuration to the first base; and (ii) second, third and fourth cross members having substantially similar configurations to the first cross member to form a sleeper. An infinite variety of furniture assemblies can be formed by using bases and cross members, respectively, having standardized, substantially similar configurations.

The spatial relationship also allows the manufacturer to scale the dimensions of the base and cross member to form the furniture assembly for individuals of different sizes. For example, the base and cross members may be proportionally sized to form a furniture assembly for children. Also, the base and cross members may be proportionally sized to form a furniture assembly for adults, or even adults of an oversized size. As a result, a variety of different sizes of furniture can be formed using the base and cross member of the present invention.

The configuration of the base and cross members of the present invention provides a number of benefits to both the user and the retailer. For example, the present invention enables a user to move a piece of furniture to a remote location where other pieces of furniture could not be moved due to their bulkiness and/or size. The present invention is easily disassembled, thus enabling a user to place the base and/or cross member in an otherwise inaccessible location and then assemble them to form the furniture assembly. In addition, the present invention enables a manufacturer and/or retailer to be provided with two pieces of furniture, namely a base and a cross member. This is advantageous for both transport and storage. For example, a manufacturer and/or retailer need only store two pieces of basic furniture and can stack various bases or cross members having the same configuration on top of each other when loading and unloading goods. Also, the bases and cross members may be stacked in an orderly fashion during storage.

In addition, the cross-member and base include a removable outer liner. Such a removable outer liner allows a user to easily clean the furniture assembly. In addition, the use of a removable outer liner allows a user to interchange liners of different shades and styles to create a unique and customized furniture assembly. Thus, the furniture assembly of the present invention is versatile, modular, interchangeable and convenient.

These and other objects and features of the present invention will become more fully apparent from the following description and appended claims, or may be learned by the practice of the invention as set forth hereinafter.

Detailed Description

The present invention relates to modular furniture assemblies that can be quickly and efficiently assembled, disassembled, rearranged, moved, and cleaned with minimal effort. The present invention further relates to modular furniture assemblies having spatial relationships that enable a user to form a variety of different furniture assemblies. In an exemplary embodiment, a modular furniture assembly includes a base, at least one cross-member, and a coupler configured to removably couple the cross-member to the base to form a chair. The configuration of the base and cross member enables a user to form a variety of different furniture assemblies.

The base serves as a support surface on which a user may sit, while the cross member serves as a resting surface for the user's back or arms. The base is configured to enable the cross member to be positioned adjacent the base in a plurality of positions and to enable the cross member to be removably coupled to the base to form different types of furniture assemblies. The coupler is configured to enable a user to quickly couple and decouple the cross member and the base with minimal effort and without the use of tools. Easily coupling the cross member to the base provides the ability to easily form furniture assemblies of a variety of configurations. A number of different furniture assemblies may be formed using a plurality of bases and cross members. Further, the base and cross members may be sized proportionally to accommodate individuals of different sizes. In this way, furniture of various types, sizes and configurations can be realized in a quick and convenient manner using the present invention.

FIG. 1 illustrates an exemplary embodiment of a modular furniture assembly 10. In the illustrated embodiment, modular furniture assembly 10 includes a base 12 and a transverse member 14 removably coupled to base 12 by a coupler 15 (FIG. 4). Base 12 and transverse member 14 are adapted to be removably coupled to one another in a variety of ways and configurations to form a variety of unique and self-contained furniture assemblies. In addition, the size and configuration of base 12 and transverse member 14 are determined according to a defined spatial relationship. The spatial relationship defined between base 12 and transverse member 14, as will be described more fully hereinafter, enables: (i) conveniently forming a plurality of different types of furniture components; (ii) conveniently forming a plurality of differently configured furniture components; and (iii) having the manufacturer scale the dimensions of the base and cross members for individuals of different sizes, such as children or adults.

The base 12 is configured to provide a comfortable seating surface for a user. The base 12 is also configured to be easily removed for rearrangement, movement, storage and/or transportation. In the present embodiment, the base 12 includes a frame assembly 16, a cushion 18, and a plurality of feet 20a-20d mounted on the frame assembly 16. The frame assembly 16 is configured to support the weight of a user while seated on the base 12. The cushion 18 is configured to be mounted to the frame assembly 16 to provide a useful and comfortable seating area for the user. The cushion 18 may be easily mounted on the frame assembly 16 or removed from the frame assembly 16.

Feet 20a-20d are coupled to the underside of frame assembly 16. The feet 20a-20d may be coupled to the frame assembly 16 in a variety of ways. In one embodiment, feet 20a-20d are coupled by screws. In the present embodiment, feet 20a-20d may be easily coupled to and/or removed from frame assembly 16 to facilitate packaging, shipping, storage, removal, and/or replacement of feet 20a-20 d. However, the feet 20a-20d may be coupled to the frame assembly 16 in a more permanent manner, such as with nails, epoxy or glue, or any combination thereof. When used with a foot coupler, such as foot coupler 34 and/or 34a, feet 20a-20d facilitate coupling of transverse member 14 to base 12. The feet 20a-20d are further configured to support the weight of the user and raise the base 12 above the floor. The removability of the feet 20a-20d, along with the removability of the cushion 18, enables the base 12 to be easily removed for rearrangement, movement, storage and/or transportation when the feet 20a-20d are coupled to the frame assembly 16 by screws.

Base 12 includes a plurality of abutment surfaces 26a-26d configured to be positionable adjacent to an abutment surface 28 of cross member 14 and to abut abutment surface 28. As will be discussed more fully herein, base 12 is configured to enable cross-member 14 to be positioned adjacent any of abutment surfaces 26a-26d to form a variety of different furniture assemblies.

In the illustrated embodiment, the base 12 and the transverse member 14 have a defined spatial relationship. The spatial relationship between base 12 and transverse member 14 enables the formation of a variety of different types, sizes and configurations of furniture assemblies. In the present embodiment, the base has a length (x) and a width (y), wherein the length (x) of the base 12 is greater than the width (y) of the base 12, and the cross member 14 has a length (x ') and a width (z), wherein the length (x') of the cross member 14 is greater than the width (z) of the cross member 14. In the present embodiment, base 12 and cross member 14 are configured such that the length (x) of base 12 is substantially equal to the length (x') of the cross member, and the length (x) of base 12 is substantially equal to the sum of the width (y) of base 12 and the width (z) of cross member 14. Thus, (x) is substantially equal to (y) + (z). The relationship of the length (x) of base 12 being substantially equal to the sum of the width (y) of base 12 and the width (z) of transverse member 14 is a defined spatial relationship between base 12 and transverse member 14. Moreover, the height (h') of cross member 14 is substantially greater than the height (h) of base 12, so that cross member 14 can be conveniently used as a backrest or armrest when base 12 is used as a seat.

This defined spatial relationship enables a user to conveniently form a variety of different types of furniture assemblies. For example, in the illustrated embodiment, a chair is formed using a first base 12 and a first cross member 14. A second and third cross member 14 having a substantially similar configuration to the first cross member 14 can be added to form an armchair with a first and a second armrest as shown in figure 6 c. The phrase "substantially similar configuration" as used herein means that the base and/or cross-member are sized and configured, respectively, so as to be interchangeable. Optionally, the couch may be formed by adding: (i) a second base 12 having a substantially similar configuration to the first base 12; and (ii) second, third and fourth cross members 14 shown in fig. 6e and 6f having substantially similar configurations as the first cross member 14. The ability to add a base and/or cross member to form different types of furniture is the reason that the defined spatial relationship enables a user to conveniently form a variety of different types of furniture.

As further shown in fig. 6e-6f, the defined spatial relationship enables a user to conveniently form furniture in a variety of different configurations. For example, couches formed using two bases 12 and four cross members 14 may be arranged to form a two-person seat as shown in fig. 6e, or a deep sofa as shown in fig. 6 f. The double seat shown in figure 6e and the deep sofa shown in figure 6f use the same base 12 and the same cross member 14 but are arranged differently. The defined spatial relationship of the present invention thus enables a user to conveniently form furniture assemblies of a variety of different configurations.

The defined spatial relationship also enables manufacturers to manufacture different sizes of bases and cross members to accommodate different sized individuals. For example, a manufacturer can manufacture the base and the transverse member such that when the base and the transverse member are removably coupled together, a furniture assembly is formed that is sized for a child, but may be too small for an adult to comfortably use. On the other hand, by utilizing the defined spatial relationship, the manufacturer may increase the size of the base and cross member such that when the base and cross member are coupled together a furniture assembly sized for an adult is formed. In this manner, the spatial relationship between base 12 and transverse member 14 enables the formation of a variety of different sized furniture assemblies.

With continued reference to fig. 1, cross-member 14 is configured to provide lateral support to a user when base 12 is coupled thereto. The cross member 14 may be positioned adjacent any of the abutment surfaces 26a-26d of the base 12 to form various furniture assemblies. A plurality of feet 30a-30b are coupled to the underside of transverse member 14. Feet 30a-30b facilitate coupling of transverse member 14 to base 12. Feet 30a-30b are further configured to support the weight of a user and lift cross member 14 above the floor upon which cross member 14 is positioned. Feet 30a-30b may be coupled to transverse member 14 in a manner similar to feet 20a-20d being coupled to base 12.

In one embodiment, feet 30a-30b are each positioned offset an equal distance, i.e., "offset distance," from the front and rear surfaces and respective adjacent side surfaces of transverse member 14. For example, if the width (z) of the cross member is 10 inches, then the offset distance is 5 inches. Thus feet 30a-30b are each positioned 5 inches offset from the front surface of the transverse member and 5 inches offset from the rear surface of the transverse member (i.e., intermediate the front and rear surfaces), and are each positioned such that they are 5 inches offset from the respective adjacent side surface of transverse member 14. Likewise, feet 20a-20d of base 12 are each positioned offset from a respective adjacent abutment surface 26a-20d by the offset distance. Thus, in one such embodiment: (i) foot 20a is offset from both abutment surface 26a and abutment surface 26b by the offset distance; (ii) foot 20b is offset from both abutment surface 26b and abutment surface 26c by the offset distance; (iii) foot 20c is offset from both abutment surface 26c and abutment surface 26d by the offset distance; and (iv) foot 20d is offset from both abutment surface 26d and abutment surface 26a by the offset distance.

In the illustrated embodiment, modular furniture assembly 10 also includes a plurality of foot couplers 34-35, which may be, for example, identical. Foot couplers 34-35 are configured to facilitate coupling of transverse member 14 to base 12. Foot couplers 34-35 are also adapted to provide support to base 12 and transverse member 14 when connected thereto. Foot coupler 34 utilizes foot 20d of base 12 and foot 30a of transverse member 14 adjacent to foot 20d of base to assist in coupling transverse member 14 to base 12. Likewise, foot coupler 35 utilizes foot 20c of base 12 and adjacent foot 30b of transverse member 14 to assist in coupling transverse member 14 to base 12.

In the illustrated embodiment, the cross member 14, frame assembly 16, and cushion 18 include selectively removable outer liners 32, 22, 24, respectively. As discussed more fully herein, the removable outer liners 32, 22, 24 are configured to be easily removed and reattached so as to be conveniently cleaned. Moreover, the selective removability of the outer liners 32, 22, 24 enables the user to mix and match colors and designs to create a unique and customized furniture assembly.

Fig. 2 shows an exploded cut-away view of the base 12. In the illustrated embodiment, the frame assembly 16 includes a frame 36 and a cushioning assembly 38 associated with the frame 36. Frame 36 is constructed and arranged to support the weight of a user using modular furniture assembly 10. The frame 36 can include a plurality of structural members made of wood, metal, composite, plastic, or any other structural material or combination thereof. One of ordinary skill in the art will appreciate that the structural members forming the frame 36 and their orientation may be altered and/or rearranged to meet different specifications, such as size and/or weight requirements.

In the illustrated embodiment, the frame assembly 16 also includes a support member 58 mounted on the frame 36. The support member 58 is positioned in the recess 44 of the frame 36. For example, in one embodiment, the support members 58 are mounted on four upright posts 59 and/or upright plates 61 positioned in the recess 44. The support member 58 comprises a sheet-like material, such as wood or some other structural material, and the support member 58 has a plurality of recesses 62a-62f formed therein. The grooves 62a-62f are located along the periphery of the support member 58 and are sized to receive a portion of the coupler 15 therein. Grooves 62a-62f are positioned in support member 58 to provide various coupling locations on base 12 for coupling of transverse member 14 to base 12 and/or coupling of base 12 to another base 12.

The grooves 62a-62f each form a hole portion in the frame assembly 16 (see fig. 5b) when the support member 58 is positioned in the recess 44 of the frame assembly 16. In the illustrated embodiment, two grooves 62a-62b, 62d-62e are positioned adjacent the respective abutment surfaces 26a, 26c, and one groove 62c, 62f is positioned adjacent the respective abutment surfaces 26b, 26 d. Two recesses 62a-62b, 62d-62e are positioned adjacent respective abutment surfaces 26a, 26c to enable the cross member 14 to be positioned in two different positions adjacent each abutment surface 26a, 26 c. The ability to position the cross member 14 at multiple locations adjacent the base 12 enables different furniture configurations to be formed. In this way, cross member 14 may be positioned and coupled to base 12 by couplers 15 in at least six different positions relative to base 12. This may be accomplished, for example, by aligning the apertures 64 (FIG. 3) of the cross member 14 with any of the grooves 62a-62f and by placing a portion of the coupler 15 in each aperture 64 and in the desired aperture of the frame assembly 16.

Thus, the configuration and positioning of the recesses 62a-62f in the support member 58 facilitates different positioning of the transverse member 14 relative to the base 12, which allows for the manufacture of modular furniture assemblies of various shapes and configurations. For example, aperture 64 of cross member 14 may be aligned with any of recesses 62a-62 f. Once aligned, a coupler 15 (FIG. 4) may be used to connect base 12 and transverse member 14, as shown in FIG. 5 b.

Likewise, the groove 62c or 62f of the first base 12 may be aligned with the groove 62c or 62f of the second base 12 to couple the two bases together, as shown in fig. 6 b. The versatility of being able to couple multiple bases 12 and cross members 14 enables a variety of different and unique furniture assemblies to be manufactured. The first base 12 may be coupled to the second base 12 by aligning the holes of the first base 12 and the holes of the second base 12 and placing a portion of the coupler 15 in the holes of the first base 12 and the holes of the second base 12. Fig. 6a-6j illustrate examples of various furniture assemblies formed from base 12 and cross-member 14 by coupling base 12 to cross-member 14 and/or base 12 using couplers 15 as shown.

Returning now to FIG. 2, cushioning assembly 38 includes a plurality of cushioning members 40a-40c attached to an outer surface of frame 36, and a cushioning member 40d mounted to support member 58 when support member 58 is mounted within frame 36. Cushioning members 40a-40c, 40d are configured to provide a cushioning surface to a user using modular furniture assembly 10. Cushioning of the frame 36 with the cushioning assembly 38 provides a more comfortable piece of furniture.

Cushioning members 40a-40c each comprise a rectangular piece of foam adapted to be positioned on the outer side surface of a respective frame 36 so as to cover the outer side portions of frame 36. Fig. 2 does not show additional rectangular foam pieces used to cushion the frame surface adjacent to the abutment surface 26 c. These cushioning members 40a-40c (including the attachment adjacent the abutment surface 26 c) may comprise various types of foam to accommodate the desired resiliency and cushioning of the frame assembly 16; these cushioning members 40a-40c may comprise a single piece of foam or may comprise an assembly of foam layers, such as a memory foam layer positioned over a polyurethane foam layer. In the illustrated embodiment, cushioning members 40a-40c are covered by an inner liner 46.

In this embodiment, cushioning member 40d also includes a foam piece covered by a liner 42. Cushioning members 40d are configured to be positionable within recesses 44 of frame 36 over support members 58. The foam pieces of cushioning members 40d may comprise a single piece of polyurethane foam, or an assembly of different types of foam. For example, cushioning member 40d may include a single piece of polyurethane foam and a similarly shaped piece of memory foam positioned over the single piece of polyurethane foam to form cushioning member 40 d. Cushioning members 40d are configured to facilitate providing a comfortable seating surface for a user using modular furniture assembly 10.

Liner 42 and inner liner 46 are configured to cover and provide protection to cushioning members 40a-40d of frame assembly 16. The liner 42 and the inner liner 46 may comprise a permeable or impermeable fabric material. An advantage of a water impermeable liner is that the liner will help protect frame 36 and cushioning members 40a-40d if a liquid, such as soda, spills onto frame assembly 16.

The frame assembly 16 also includes a removable outer liner 22. The removable outer liner 22 is configured for use with the frame assembly 16 to provide additional protection to the frame 36 and cushioning members 40a-40c and for aesthetic reasons. The removable outer liner 22 is mounted on the inner liner 46 so as to cover the exposed portion of the inner liner 46 when the cushion 24 is mounted thereon.

In the illustrated embodiment, the outer liner 22 is removably coupled to the frame assembly 16 by a removable fastening mechanism 48, such as a hook and loop mechanism (e.g., VELCRO). In this manner, the outer liner 22 can be selectively removed and cleaned when it becomes dirty and/or soiled. Removable fastening mechanisms 48, such as velcro, also assist the user in easily, quickly, and efficiently reattaching the outer liner 22 to the inner liner 46 of the frame assembly 16. In addition, the selective removability of outer liner 22 also facilitates the ability of a user to mix and match the outer liners of modular furniture assemblies 10 of various styles, designs and configurations to form customized and unique modular furniture assemblies according to the needs and tastes of the user.

As previously mentioned, the base 10 includes a plurality of abutment surfaces 26a-26 d. In the illustrated embodiment, the abutment surfaces 26a-26d are respective, substantially flat surfaces configured to be positioned adjacent and abut the substantially flat abutment surface 28 of the cross member 14. Abutment surface 28 of transverse member 14 is configured to correspond with at least one of the abutment surfaces 26a-26d of base 12 when base 12 is placed in abutting relationship with transverse member 14. In this manner, cross member 14 can be coupled to base 12 using coupler 15.

The cushion 18 is configured to be positioned and mounted on the frame assembly 16 to form the base 12. The cushion 18 is sized so that its perimeter is substantially equal to the perimeter of the frame assembly 16. In the illustrated embodiment, cushion 18 includes a foam piece 50 covered by an inner liner 52. Foam member 50 comprises a single foam member having sufficient resiliency and suitable characteristics to provide a comfortable seating surface when a user is seated on modular furniture assembly 10. However, the foam member 50 may include various types and configurations of foam members, such as a polyurethane foam layer and a memory foam layer mounted on the polyurethane foam layer.

As previously mentioned, the inner liner 52 covers the foam member 50. The inner liner 52 may comprise a fabric material sufficient to substantially cover the foam member 50. Inner liner 52 may be made of substantially the same material as inner liner 46 and/or liner 42.

In the illustrated embodiment, the inner liner 52 is covered by the removable outer liner 24, thereby providing an aesthetically pleasing and comfortable cushioning surface on which a user may sit. The removable outer liners 24, 22 may be similar. The removable outer liners 22, 24 may comprise a variety of different materials and may be attached in a variety of ways. For example, removable outer liners 22, 24 may be made of materials such as cotton, leather, microfiber, suede, or any other material that a user may wish to use.

Removable outer liners 22, 24 may be removably coupled using removable fastening mechanisms such as hook and loop mechanisms, e.g., velcro, one or more zippers, male and female snap members, hook and lock fasteners, or any other type of fastening device that will facilitate selective removal of outer liners 22, 24. In this manner, a user may choose to mix and match different types, styles and configurations of removable outer liners 22, 24 to form a customized furniture assembly according to the user's needs and tastes.

Fig. 3 is a partial cut-away view showing cross member 14. Cross member 14 is configured to be coupled to base 12 to form modular furniture assembly 10. As further shown in FIG. 3, cross member 14 is further configured to be positioned such that the longitudinal axis of cross member 14 is substantially transverse to a plane of a support surface, such as the ground or floor, on which cross member 14 is mounted.

In the illustrated embodiment, transverse member 14 includes a frame assembly 54, an inner liner 56 covering frame assembly 54, a removable outer liner 32, feet 30a-30b coupled to an underside of frame assembly 54, and a hole 64 formed within frame assembly 54 that facilitates coupling transverse member 14 to base 12.

Frame assembly 54 is configured to provide lateral support to a user using modular furniture assembly 10. The frame assembly 54 is also configured to provide a comfortable surface on which a user may rest. In the illustrated embodiment, the frame assembly 54 includes a frame 66 and a cushion assembly 68. Frame 66 is configured to provide lateral support to a user sitting on modular furniture assembly 10 when cross-member 14 is coupled to base 12. The frame 66 may include a plurality of structural members made of wood, metal, composite, plastic, or any other structural material or combination thereof. One of ordinary skill in the art will appreciate that the structural members forming the frame 66 and their orientation may be modified and/or rearranged to meet different specification requirements, such as size and/or weight.

Cushioning assembly 68 includes a plurality of cushioning members 70 and a wedge 72 associated with frame 66 to provide a cushioned comfort surface. In the illustrated embodiment, wedge 72 comprises a piece of foam shaped like a wedge. The wedge 72 is configured to mount on the angled front surface of the frame 66 to form a rectangular solid with the frame 66. The cushioning member 70 is configured to surround and cover the frame 66 and the wedge 72. Cushioning members 70 comprise pieces of foam of sufficient size to cover both frame 66 and wedges 70. Overlying cushioning assembly 68 is inner liner 56 and removable outer liner 32. Inner liner 56 may have similar characteristics as inner liners 46, 52 and liner 42. Likewise, removable outer liner 32 may have similar characteristics as outer liners 22, 24.

Apertures 64 are configured and positioned to facilitate coupling of cross-member 14 to base 12. The aperture 64 is centrally located adjacent the abutment surface 28 of the cross member 14 to form various types and configurations of furniture assemblies. Aperture 64 is also positioned to be capable of aligning with any of recesses 62a-62f such that cross member 14 may be positioned in relation to base 12 in a variety of ways. An aperture 64 extends through the frame assembly 54 and the inner and outer liners 56, 32. The aperture 64 is of a size sufficient to allow a portion of the coupler 15 to be received through the aperture 64.

Figure 4 is a perspective view showing some of the couplers including coupler 15 and foot couplers 34, 34 a. Coupler 15 is configured to removably couple cross-member 14 to base 12. In the illustrated embodiment, coupler 15 comprises an elongated U-shaped member configured to be positionable within aperture 64 of cross member 14 and one of grooves 62a-62f of support member 58, or one of grooves 62a-62f of first base 12 and one of grooves 62a-62f of second base 12 when the two bases are coupled together. Coupler 15 is also configured to engage the inner surfaces of frame 36 of base 12 and frame 66 of cross member 14, as shown in fig. 5b and 5c, so as to sandwich a portion of cross member 14 and a portion of base 12 between the coupler 15 portions. Coupler 15 is configured to substantially prevent movement of an upper portion of transverse member 14 relative to base 12. In this manner, the coupler 15 substantially prevents movement of the cross member 14 relative to the base 12 in at least the first direction.

The coupler 15 may be made of a metallic material or some other structural material. The coupler 15 may include a hole on the top surface of the coupler 15 to facilitate easy insertion and removal of the coupler 15. The coupler 15 has a first leg 15a coupled to a body portion 15b, and the body portion 15b has a second leg 15c coupled thereto. In one embodiment, first leg 15a is longer than second leg 15c to facilitate coupling of base 12 to cross member 14 and to resist forces generated on coupler 15. In another embodiment, the first leg 15a is substantially the same length as the second leg 15 c.

Coupler 15 and foot couplers 34, 34a can be used to help removably couple transverse member 14 to base 12. In the illustrated embodiment, foot coupler 34 includes a block portion having a plurality of apertures 74a-74b formed therethrough. Apertures 74a-74b are sized and configured to receive a foot of either base 12 or transverse member 14. Apertures 74a-74b of foot coupler 34 are spaced sufficiently large such that when foot 30 from transverse member 14 is positioned in aperture 74a and foot 20 from base 12 is positioned in aperture 74b, transverse member 14 and base 12 are adjacent and in contact with each other.

Foot couplers 34-35 are configured to substantially prevent translational movement of the bottom of transverse member 14 relative to base 12. In this manner, movement of foot couplers 34-35 substantially prevents movement of transverse member 14 relative to base 12 in at least a second direction. For example, in the embodiment shown in FIGS. 5a-5c, coupling 15 substantially prevents movement of the top portion of transverse member 14 in at least a first direction, i.e., away from base 12, while foot couplings 34-35 substantially prevent movement of the top portion of transverse member 14 in at least a second direction, i.e., toward base 12.

Yet another embodiment of foot coupler 34a is shown in FIG. 4. Foot coupler 34a functions similarly to foot coupler 34. Foot coupler 34a can replace foot coupler 34 and have additional holes for connecting additional feet. Thus, foot coupler 34a is configured to substantially prevent movement of the bottom of transverse member 14 relative to base 12.

Foot coupler 34a has four apertures 74a-74d to enable foot coupler 34a to be utilized in coupling base 12 to a plurality of transverse members 14 and/or base 12 to form a furniture assembly as shown in fig. 6c-6 j. For example, in the embodiment of fig. 6c, one foot coupler 34a is used to couple one leg of base 12 to one leg of a first cross member 14 positioned to serve as a backrest and one leg of a second cross member 14 positioned to serve as an armrest, while another foot coupler 34a is used to couple a second leg of base 12 to a second leg of first cross member 14 and one leg of a third cross member 14 positioned to serve as another armrest. In this example, one hole in each foot coupler 34a is not used, but the symmetrical configuration of foot couplers 34a enables a user to employ foot couplers 34a in a variety of differently configured furniture assemblies.

One of ordinary skill in the art will note that the foot coupler of the present invention need not be limited in the number of apertures 74 formed therein. For example, the foot coupler of the present invention may be sized and configured to include a suitable number of apertures to couple the feet of two bases 12 and four cross members 14 to facilitate forming a sofa. Alternatively, the foot coupler can have any number of apertures necessary to couple the foot 20 of the base 12 to the foot 30 of the transverse member 14 or the foot 20 of another base 12, and/or to couple a respective foot 20 of a plurality of bases 12 to a respective foot 30 of a plurality of transverse members 14, and the apertures can be in any configuration. In one embodiment, aperture 74 includes a tapered opening to make it easier for a user to insert a foot therein. In an alternative embodiment, the foot coupler comprises 3 holes. In another embodiment, the foot coupler includes 5 holes. In yet another embodiment, the foot coupler includes 6 holes.

Fig. 5a-5c illustrate how modular furniture assembly 10 is assembled. As shown in this embodiment, the frame assembly 16 of the base 12 is positioned against the cross member 14 such that the aperture 64 is adjacent to and aligned with the recess 62f in the support member 58. Once aligned, coupler 15 is positioned within aperture 64 of cross-member 14 and depressed by the user to engage the inner flat surface of frame 66 of cross-member 14 and the inner flat surface of frame 36 of base 12, as shown in fig. 5b and 5 c. In this manner, coupler 15 is connected to base 12 and cross member 14.

In addition, foot 20d of base 12 is received into aperture 74b of foot coupler 34, and foot 30a of transverse member 14 is received into aperture 74a of foot coupler 34. Likewise, foot coupler 35, which is similar or identical to foot coupler 34, is utilized in a similar manner as foot coupler 34, with foot 20c received into aperture 74b of foot coupler 35 and foot 30b received into aperture 74a of foot coupler 35. In this manner, transverse member 14 is removably coupled to base 12 using coupler 15 and foot couplers 34-35 to form furniture assembly 10 of the present invention.

One of ordinary skill in the art will note that a user can easily and quickly use coupler 15 and foot couplers 34, 34a, and/or 35 to manually removably couple base 12 to transverse member 14 and/or another base 12. For example, the user does not require tools to connect or disconnect the coupler 15 to the base 12 and cross member 14. Since no tools are required, a user can manually connect coupler 15 and foot couplers 34, 34a, 35 to base 12 and transverse member 14 and/or another base 12, or disconnect the connections, as the case may be. Thus, the phrase "manually, removably coupled" as used herein means that the coupler and foot coupler conveniently couple or uncouple base 12 and transverse member 14 and/or another base 12 without the use of tools such as a hammer or screwdriver, or some other mechanized machinery.

Once coupler 15 is connected to base 12 and transverse member 14, cushion 18 may be placed on frame assembly 16 to form furniture assembly 10. One of ordinary skill in the art will note that foot couplers 34, 34a and coupler 15 may be easily manually disconnected or removed to disassemble modular furniture assembly 10.

FIG. 5b is a perspective view of modular furniture assembly 10 showing coupler 15 removably coupling transverse member 14 to base 12. In this figure, coupler 15 is received through aperture 64 of cross member 14 and base 12. The hole in the base 12 through which the coupler 15 is received is formed by the groove 62f and the frame 36. In this manner, coupler 15 is utilized to assist in coupling cross-member 14 to base 12. In addition, foot couplers 34 are mounted on feet 20d and 30a, and foot couplers 35 are mounted on feet 20c and 30 b.

FIG. 5c shows a cross-sectional view of modular furniture assembly 10 when coupler 15 and foot couplers 34-35 are connected to base 12 and transverse member 14. As shown in this embodiment, when coupler 12 is connected to base 12 and cross member 14, coupler 12 sandwiches the substantially straight portion of frame 34 and the substantially straight portion of frame 66. When coupler 15 is connected to base 12 and cross member 14, coupler 15 is received in aperture 64 and groove 62 f. Foot coupler 35 also illustrates how foot 30b of transverse member 14 and foot 20c of base 12 are received in foot coupler 35.

Utilizing base 12, transverse member 14, coupler 15, and foot couplers 34-35 enables modular furniture assembly 10 to be assembled in a quick and efficient manner. Likewise, the ability to easily remove coupler 15 and foot couplers 34-35 allows a user to easily remove or disassemble modular furniture assembly 10 to move and/or package modular furniture assembly 10.

For example, a user may purchase the base 12, the cross member 14, the coupler 15, and the plurality of foot couplers 34-35, and then assemble them to form a modular furniture assembly, such as a chair, having a back and a base. By positioning base 12 adjacent to transverse member 14, inserting couplers 15 into engagement with the frame of transverse member 14 and the frame of base 12, a user can easily assemble the modular furniture assembly, and then position foot couplers 34-35 over the feet on opposite sides of base 12 and transverse member 14 to form a secure and comfortable chair, as shown in FIG. 1. If the user desires to move the chair, the chair can be easily disassembled by removing the couplers and foot couplers to form two separate sections that can be easily moved and reassembled to form the furniture assembly.

Advantages offered to the user with respect to moving furniture components are also provided in shipping and packaging. For example, a manufacturer of modular furniture assemblies may package the cross member separately from the base. The uniform rectangular shape of the cross member and base facilitates packaging and shipping of the cross member and base. By employing base 12 and transverse member 14, a manufacturer and/or retailer can manufacture, store, and ship a large number of two types of furniture pieces, thereby increasing the efficiency of the manufacturing, shipping, and storage processes. Further, if the feet are threaded onto the transverse member and base, the transverse member and base can be easily removed and reattached to facilitate shipping and shape unification of the transverse member with the base.

Figures 6a to 6i show furniture assemblies according to the invention manufactured with cross members and bases in different configurations as the case may be. In one embodiment, each of the bases 12 shown in fig. 6a-6j has substantially the same dimensions as each of the other bases 12 shown therein such that the bases 12 are interchangeable, and each of the transverse members 14 shown in fig. 6a-6j has substantially the same dimensions as each of the other transverse members 14 such that the transverse members 14 are interchangeable.

Figure 6a shows the use of the base 12 alone to form an armless lounge chair. Figure 6b shows a configuration of a bench in which two bases 12 are coupled together to form the bench. Figure 6c shows the configuration of the armchair. In this embodiment, three cross members 14 are utilized in conjunction with a base 12 to form a chair. FIG. 6d shows the configuration of a lounge chair formed with two bases 12 and two cross-members 14 coupled together.

A suitable number of couplers 15 may be used for each furniture construction shown in fig. 6a-6 j. For example, a single coupler 15 is used to couple the base 12 to form the bench of FIG. 6 b. Alternatively, first and second couplers 15 are used to couple the base 12 to form a bench as in fig. 6 b. First, second, and third couplers 15 are used to couple respective cross members 14 to base 12 to form a chair as shown in fig. 6 c. In one embodiment, in the lounge chair of FIG. 6d, a single coupler 15 is employed to couple base 12 to base 12, and second and third couplers 15 are used to couple respective cross members 14 to one of bases 12. The assembly shown in fig. 6e-6j may be similarly coupled together using couplers, such as coupler 15 to couple the respective base 12 and transverse member 14 together into a desired configuration.

Fig. 6e shows a sofa formed with two bases 12 and four cross members 14. Fig. 6f shows a deep two-seater seat formed with two bases 12 and four cross members 14 detachably coupled together. Fig. 6g shows the construction of a modular furniture having six bases 12 and seven transverse members 14 coupled together. Fig. 6h shows a configuration of a twisted design, formed with four bases 12 and four cross members 14. Fig. 6i illustrates the configuration of a playpen formed with four bases 12 and eight cross members 14 removably coupled together, as shown in fig. 6 i. Fig. 6j shows a configuration of a bed in which six bases 12 are coupled together to form a bed and two cross members 14 are coupled to two bases 12 to form a headboard. In this manner, the six bases 12 are constructed and arranged for a user to sleep on. In one embodiment, couplers 15 are employed to form a connection between each base 12 and cross member 14 and/or other bases 12 in the embodiment shown in FIGS. 6a-6 j.

Fig. 7 shows an alternative embodiment of the base 112. In the illustrated embodiment, the frame 136 is configured such that the support members 158 are angled. The angled design of the support portion 158 allows the user to naturally lean against when seated on the base 112. In this embodiment, cushioning members 140e are wedge-shaped pieces of foam configured to be received within recesses 144 of frame assembly 116 to form a flush top surface.

In the illustrated embodiment, the cushion 118 includes a plurality of pieces of foam to form a cushion for a user sitting thereon to lean against. For example, cushion 118 may include a first foam wedge 120 and a second foam wedge 122 positioned adjacent to first foam wedge 120 to form a rectangular solid. A memory foam layer 124 may be positioned over second foam wedge 122 to form cushion 118 on which a user may sit. One of ordinary skill in the art will note that the memory foam layer 124 provides additional comfort to a user sitting on the base 112. First foam wedge 120 may be denser than second foam wedge 122 such that second foam wedge 122 is more elastically deformed when pressure is applied thereto, such as when a user sits on cushion 118. The difference in density of the two foam wedges 120, 122 allows the user to naturally lean against when seated on the cushion 118.

FIG. 8 illustrates another embodiment of a base and various couplers. In this embodiment, base 212 includes a frame assembly 216 having a frame 236 and a plurality of mounting plates 261 mounted on frame 236. Frame 236 includes a support member 258, and a cushion or cushioning member may be mounted on support member 258. The support member 258 includes a solid, substantially flat surface. In this embodiment, the support member 258 does not include a groove. When the coupler 15 is used with the base 212, the first end 15a of the coupler 15 may be shortened so as not to interfere with the support member 258. One of ordinary skill in the art will appreciate that base 12 and base 212 may be used in the same furniture assembly.

Mounting plate 261 is an enhanced, substantially flat surface that is configured and positioned to conveniently, manually, removably couple base 212 to cross member 14 via coupler 15, flared coupler 215, and/or ratcheting (ratcheting) coupler 217. Mounting plate 261 is positioned along the perimeter of frame 236 in a manner similar to the positioning of grooves 62a-62f with respect to base 1. The respective positioning of mounting plates 261 along the periphery of base 212 enables cross-member 14 to be quickly and efficiently positioned with respect to base 212 to form a desired furniture assembly. Mounting plate 261 is mounted on the inner surface of frame 236 and/or on cross-member 14.

Flare coupler 215 comprises a U-shaped member having terminal flare ends that are bent outwardly relative to each other. The flared end is curved to facilitate insertion of coupler 215 into cross member 14 and base 212. Base 212 is removably coupled to cross member 14 and/or another base 212 manually using flared coupler 215 in the same or similar manner as coupler 15, as shown in fig. 6b-6 j. The lengths of the legs of flared couplers 215 may, for example, be substantially the same, or may be different.

In the illustrated embodiment, ratcheting coupler 217 includes a first portion 217a, a second portion 217b, and a ratcheting portion 217c, ratcheting portion 217c being configured such that base 212 can be removably coupled to transverse member 14 manually. The first portion 217a is configured to be selectively received within and secured by the ratcheting portion 217 c. Ratcheting portion 217c is coupled to second portion 217b and is configured to selectively receive and secure first portion 217a therein. Ratcheting portion 217c is also configured to advance first portion 217a into ratcheting portion 217c as ratcheting portion 217c is actuated. Ratcheting portion 217c is further configured to selectively release first portion 217a therefrom to enable a user to quickly and efficiently detach first portion 217a from second portion 217 b.

In the illustrated embodiment, first portion 217a is coupled to base 212 and second portion 217b is coupled to transverse member 14. For example, the first portion 217a may be selectively coupled to any mounting plate 261. First portion 217a is secured to second portion 217b to manually, removably couple base 212 to transverse member 14. Ratcheting coupler 217 may be used with base 12.

A useful example of one type of ratcheting coupler 217 is a coupler commonly used with snowboard bindings. The ratcheting coupler 217, which is commonly used with snowboard bindings, includes a first strip (strap) having a plurality of grooves formed perpendicular to the length of the first strip and an associated second strip having a ratcheting mechanism coupled thereto. The first strip may be received within and secured by the ratcheting mechanism. The ratcheting mechanism includes a lever that, when grasped and actuated, will advance the first strip into the ratcheting mechanism by contacting a groove in the first strip. Generally, means are provided for releasing the first strap from the ratcheting mechanism, such as a button or additional lever, etc., such that actuation of the button or lever enables a user to easily remove the first strap from the ratcheting mechanism. In this way, the first strap is secured to the second strap.

When so selected by the user, a storage compartment 257 may be utilized with the frame 236 to store couplers or other items. The storage compartment 257 may be sized and configured to accommodate a large number of various couplers therein. The storage compartment 257 may be closed by using a trap door (trap door)259 formed in the support member 258. Storage compartment 257 provides a useful and convenient storage area for storing some of the user's items and/or hardware associated with the furniture assembly.

Coupler 15, flared coupler 215, leg couplers 34-35, and ratcheting coupler 217 are examples of couplers that manually detachably couple base 212 (or 12) to cross member 14 and/or another base 212 (or 12). Those of ordinary skill in the art will appreciate that various types and configurations of couplers that are manually and removably coupled may be used without departing from the spirit and scope of the present invention. For example, in one embodiment, the coupler may be a mechanical hook and lock system. In another embodiment, the coupler may be a clasp, such as a clasp used on a watch. In another embodiment, the coupling may be a variety of different types of quick release systems. In yet another embodiment, the coupler may include a plurality of magnets. In yet another embodiment, the coupling may comprise a snap (snap). In another embodiment, the coupler may be a strap and buckle configuration. In one such embodiment, one end of the first strap is coupled to the transverse member 14, while the recess of the buckle is coupled to the other end of the first strap. One end of the second strap is coupled to the base 12 and the other end is slidably received within the male portion of the buckle such that when the male portion is received within the female portion, the second strap is pulled to cinch the portions together.

Fig. 9 shows a schematic top view of modular furniture assembly 10. In the illustrated embodiment, modular furniture assembly 10 includes a base 12 and a cross member 14. As discussed above, the base 12 includes a plurality of feet 20a-20d coupled to an underside of the base 12. Likewise, transverse member 14 includes a plurality of feet 30a-30b coupled to an underside of transverse member 14. Feet 20a-20d of base 12 and feet 30a-30b of transverse member 14 are positioned relative to one another to removably couple base 12 to transverse member 14.

There is a particular relationship between the positioning of feet 20a-20d of base 12 relative to the side or abutment surfaces 26a-26d of base 12 and the positioning of feet 30a-30b relative to transverse member 14. This particular relationship can form a variety of different types and configurations of furniture assemblies in a quick, convenient, and cost-effective manner. For example, the positioning of feet 20a-20d relative to the base and the positioning of feet 30a-30d relative to the transverse member enable the use of standardized foot couplers to form a variety of different types and configurations of furniture assemblies.

In the illustrated embodiment, the feet 20a-20d of the base are offset from the respective adjacent sides of the base 12 by an offset distance (o). For example, foot 20b of base 12 is offset from abutment surface 26b and abutment surface 26c by an offset distance (o), such that the distance from abutment surface 26b to the center of foot 20b is offset distance (o) and the distance from abutment surface 26c to the center of foot 20b is offset distance (o). Similar to foot 20b, foot 20a of base 12 is offset from abutment surface 26b by an offset distance (o) and from abutment surface 26a by an offset distance (o). In this manner, foot 20c of base 12 is offset from abutment surfaces 26c and 26d by an offset distance (o), and foot 20d of base 12 is offset from abutment surfaces 26a and 26d by an offset distance (o). Similar to feet 20a-20d of base 12, feet 30a-30b of the transverse member are offset from adjacent respective sides by an offset distance (o) such that feet 30a-30b are positioned substantially midway between the front and rear surfaces of transverse member 14.

In the illustrated embodiment, as shown in FIGS. 1, 5, 6, 8, 9, 11, and 12, there is a particular relationship between the offset distance (o) and the distance between foot 20c of base 12 and foot 30b of transverse member 14 when, for example, base 12 is positioned against transverse member 14. In the illustrated embodiment, the distance between foot 20c of base 12 and foot 30b of transverse member 14 is represented by A. In this manner, the distance between the center of foot 20c of base 12 and the center of foot 30b of transverse member 14 is equal to distance A, which is substantially equal to twice offset distance (o).

The relationship between offset distance (o) and the distance between feet 30 of transverse member 14 and feet 20 of base 12 facilitates removably coupling base 12 to transverse member 14 and enables a user to form furniture assemblies of different types and configurations using multiple bases and multiple transverse members. The relationship between the positioning of the foot on the base and on the transverse member also enables the use of standardized foot couplers (i.e., foot couplers 34, 34a) in conjunction with multiple base and transverse members to form a variety of different types and configurations of furniture assemblies. It is also shown that the width (z) of the cross member 14 is substantially equal to twice the offset distance (o) and substantially equal to the distance a. It can be noted that the foam or padding (padding) applied to the frame of the base may become smaller in thickness.

Figure 10 shows feet 34, 34 a. In the illustrated embodiment, the distance between the center of bore 74a of foot coupler 34 and the center of bore 74b of foot coupler 34 is designated a. As described above, a is substantially equal to twice the offset distance (o). Likewise, the distance between the center of bore 74a of foot coupler 34a and the center of bore 74b of foot coupler 34a is distance a. Likewise, the distance between the centers of holes 74b and 74c of foot coupler 34a is distance a, the distance between the centers of holes 74c and 74d of foot coupler 34a is distance a, and the distance between the centers of holes 74d and 74a is distance a. In this manner, the standardized spacing of the apertures enables the use of standardized couplers to form various types and configurations of furniture assemblies according to the present invention.

Moreover, it can be noted that foot couplers of various sizes and configurations can be utilized as standardized foot couplers. For example, in one embodiment, the foot coupler includes three apertures such that the foot coupler will be sufficient to couple the foot of the base to the transverse member, as is the case with the furniture assembly shown in FIG. 1. Foot couplers may also be employed to couple: (i) the foot of the first transverse member is coupled to the foot of the base portion, (ii) the foot of the second transverse member is coupled to the foot of the base portion, and (iii) the foot of the first transverse member is coupled to the foot of the second transverse member.

FIG. 11 is a schematic top view of a modular furniture assembly having a single base 12 and three transverse members 14a-14c coupled to the base 12. As shown in the embodiments, the relationship between the position of the foot relative to the respective sides of each base and/or transverse member allows for various types of furniture assemblies to be formed utilizing standardized foot couplers 34, 34 a. In the illustrated embodiment, two foot couplers with four holes and two foot couplers with two holes are utilized. Those skilled in the art will note that foot coupler 34 may be replaced with foot coupler 34a having four apertures without departing from the scope and spirit of the present invention.

In the illustrated embodiment, a foot coupler can be utilized to assist in removably coupling the transverse member to the base when the transverse member is positioned against the base. For example, in the illustrated embodiment, foot 20a of base 12 is received in aperture 74b of foot coupler 34, and foot 30a of transverse member 14c is received in aperture 74a of foot coupler 34. Likewise, foot 20b is received in aperture 74a of foot coupler 34, while foot 30a of transverse member 14a is received in aperture 74b of foot coupler 34. Foot 20c of base 12 is received in aperture 74b of foot coupler 34a, foot 30b of transverse member 14b is received in aperture 74a of foot coupler 34a, and foot 30b of transverse member 14a is received in aperture 74d of foot coupler 34 a. Likewise, foot 20d of base 12 is received in aperture 74c of foot coupler 34a, foot 30a of transverse member 14b is received in aperture 74d of foot coupler 34a, and foot 30b of transverse member 14c is received in aperture 74a of foot coupler 34 a.

FIG. 12 is a perspective view of the modular furniture assembly showing the positioning of the groove 62 relative to the aperture 64 of the cross member 14. The distance between the abutment surface 26a and the center of the groove 62f is indicated by distance B. The positioning of the grooves in the base facilitates the ability to position one or more cross members relative to the base in a convenient and easy manner to form a variety of different types and configurations of furniture assemblies. In addition, the distance between the groove 62e and the abutment surface 26B of the base 12 is a distance B, and the distance between the center of the groove 62d and the abutment surface 26d is a distance B. Likewise, cross-member hole 64 is positioned approximately midway along the length (x ') of cross-member 14 such that the distance between the center of hole 64 and the side surface of cross-member 14 is distance B, and the length (x') of the cross-member is substantially equal to twice distance B.

The support member including the grooves 62 may be a solid piece of material, such as a wood or composite sheet. Alternatively, the support member may be a piece of material such as a fabric piece connected to the frame of the base by a plurality of springs, wherein the springs not only connect the material to the frame of the base, but also utilize the elasticity of the springs to provide a more comfortable seating surface for the user. One of ordinary skill in the art will appreciate that the spring may be sized and configured to accommodate users of different weights sitting on the base. Furthermore, the number of springs used may affect the resilience of the support member when a user is seated thereon, and may be adjusted to accommodate users of different weights.

Figure 13 is a cut-away view of base 12 coupled to transverse member 14 by coupler 15 and foot coupler 35. In the illustrated embodiment, base 12 is positioned against and abuts cross-member 14. Foot coupler 35 couples the bottom of transverse member 14 to the bottom of base 12. Because foot coupler 35 receives foot 30b of transverse member 14 and foot 20c of the base portion therein, movement of the top portion of transverse member 12 in the direction indicated by D' is substantially reduced or prevented.

For example, due in part to the frame of the cross member and base, movement of the top of cross member 14 in the D' direction is substantially reduced or prevented. For example, foot coupler 35, which receives feet 30b, 20c therein, substantially secures the bottom of the base to the bottom of the transverse member. When the base and the bottom of the cross member are substantially fastened together and the cross member is abutted against the base as shown, the top of the cross member will be restrained from movement in the direction D' due to the intersection of the frame of the base and the frame of the cross member. It can be noted, however, that the top of cross member 14 may move a minimum distance in the direction D', but this may be the result of compression of the cushioning material used to surround the base and cross member. When the top of the cross member is moved in the direction D', the respective frames of the cross member 14 and the base 12 contact each other and in this way resist movement. However, without the coupler 15 in place as shown, the top of the cross member may be able to move in direction D. Coupler 15 substantially reduces or prevents movement of the top of the cross member in direction D relative to cross member 14 in much the same manner as foot coupler 35 (i.e., through interaction of the frame of the base with the frame of the cross member).

One of ordinary skill in the art will note that foot coupler 35 may be replaced with foot coupler 34a or 35. Additionally, multiple cross members may be used to form a chair. In this manner, directions D and D 'are unambiguous to each cross member, such that direction D' for a first cross member may be the same as direction D for a second cross member. This is the case when, for example, the first and second cross members are positioned on opposite sides of the base.

The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
