An air ventilation compartment receives a removable filter to provide ventilation into the storage compartment.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention
This invention relates in general to storage enclosures and more particularly, to a frameless storage enclosure being suspended from above while being positioned on a support surface.
2. Summary of the Prior Art
In the past, many designs for storage containers have been developed for storing articles over a period of time. Such containers have been in the form of rigid trunks, hanging wardrobe units, canvas lockers, and portable closets, among many storage structures. It has been popular to construct a storage unit from flexible or collapsible material that is relatively inexpensive to manufacture and capable of being folded into a compact shape when not in use as compared to enclosures formed from rigid members.
Known containers employing collapsible sidewalls and other structural members suffer from several shortcomings, including the fact that present designs require rigid structural support frames. Examples of containers using collapsible walls and the like in conjunction with rigid internal frames are disclosed in U.S. Pat. No. 1,629,342 to N. M. Robert and U.S. Pat. No. 5,718,490 to J. Liao. The use of frames, such as in the foregoing patents, not only increases the cost and weight of the container, but severely limits the adaptability of the enclosure to various configurations of spaces in which the unit is intended to be used for storage. For example, containers requiring frames may not be advantageously for use in all areas of an attic where a sloping roof and rafters are present. In addition, the presence of framing members interferes with the convenience and efficiency of the unit to be readily collapsed into a knock-down mode for transport and storage of the container when not in use. The prior technique of using a rigid frame either requires removal to be collapsed or otherwise limits the degree of compactness when the frame remains in the unit. Another problem associated with known storage units is that they provide little or no air flow along with a highly desirable prevention of insect infestation and the introduction of dust to the items in storage in the unit. For these reasons, it is to provide an improved and inexpensive frameless storage container having the capability of effectively storing items in a sealed environment within a range of various space configurations.

SUMMARY OF THE INVENTION

It is therefore an objective of this invention to provide an improved frameless storage enclosure constructed from an inexpensive collapsible material. The enclosure herein disclosed is capable of storing articles of considerable weight because it rests on a support surface. The configuration of the collapsible members of the invention is defined by suspending the top of the unit from structural elements, such as rafters, beams, ceilings, and the like. The shape of the storage unit herein described in its erected form can be adjusted for various volumetric capacities and can easily be modified in shape for given conditions from a fully erected form or to other modified forms to be accommodated in irregular spaces, such as beneath sloped roofs, ceilings, walkways, or other space demands. The frameless storage enclosure herein provides an effective sealed environment for the stored items, but is provided with an effective access means for convenient opening and closing of storage interior as needed in use. The invention limits damage from water and also provides ample air circulation to the items being stored by an improved technique preventing the introduction of dust and insects.
The invention can accommodate a wide range of personal and business items, files, records, and collectibles among many articles that require storage for personal or business reasons. The frameless enclosure of the application can be readily used for storage at almost any location where storage of articles is desired, such as, but not limited to attics, basements, warehouses, offices, plants, garages, carports, or storage facilities.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring now to FIGS. 1-4, there is illustrated the frameless storage enclosure of the invention shown in its fully erected configuration for maximum volumetric storage capacity and being generally designated by reference numeral 2. In its fully erected form, as shown in FIGS. 1-4, the storage enclosure has six parallel rectangular walls 4 forming a cuboid shape to define an interior storage compartment or space 4 a. The enclosure 2 may be formed with sides having dimensions to form a cubical shape or because of its unique features, the enclosure 2 may be erected into a range of other configurations, including, but not limited to, being rhombohedral and other many shape dependent on encountered conditions. In FIG. 1, the frameless storage enclosure 2 is shown having six integral walls 6 to form spaced side panels 8, front panel 10, bottom wall 12, rear panel 14, and top wall 16.
The walls 6 are preferably formed from a suitably strong and collapsible material to seal the interior and define an exterior pod creating internal storage compartment 4 a for effective storage of articles. Although not intended to be so limited, an example of a suitable material for walls 6 is a woven polypropylene (PP) interconnected to form a sealed outer envelope or pod around the storage compartment 4 a. The bottom wall 12 is designed to rest on a lower support surface 12 a (FIG. 3), such as a floor, shelf, patio, or any other support surface on which the enclosure 2 is positioned. The support surface 12 a is intended to bear substantially the entire weight of the enclosure 2 and its contents when in an erected storage mode in accordance with the invention.
An access opening 20 is cut out of the front panel 14 to provide access in and out of storage compartment 4 a. The access opening 20 is selectively covered by a door 22 formed from a suitable plastic and the like, such as polyvinyl chloride (PVC). The door 22 is suitably affixed at its top portion 24 to a lower edge 26 of narrowed upper portion 28 of the front panel 10. A pair of separable zippers 30 extends from along the bottom and sides of door 22 to removeably attach the bottom 29 and side edges 29′ to the front panel 10. The lower portion 10 a of front panel 10 beneath the bottom of zippers 30 is elevated to act as a dam inhibiting the introduction of water and like of a predetermined depth into the storage compartment 4 a, if flooded conditions are present on support surface 12 a. The lower portion 10 a is sufficiently flexible to allow loading vehicles to freely move in and out of the enclosure when access door 22 is opened. When it is desired to fully open the door 22, both zippers 30 are unzipped up to the top portion 24 to allow separation of the bottom and side of the door 22. The door 22 can be rolled up and secured at an upper stowed position by a hanging strap 32 attached by stitching to top wall 16 as seen in FIG. 2. The strap 32 is extended around the door 22 in a rolled up configuration and is secured to a tab 34. The surfaces of strap 32 and tab 34 are provided with corresponding interlocking loops and hooks, such as a material sold under the trademark VELCRO.
As seen in FIGS. 1-4, four hanging flaps 40 are pivotally affixed by a suitable technique adjacent the corners 42 of the storage enclosure 2 and may be oriented in desired plane dependent on the angular orientation of hanging cords 44. The hanging cords 44 are respectively affixed to a plurality of reinforced eyelets 46 arranged in spaced relationship along strips 40 for providing a wide range of hanging options dependent on the overhead structure of the space in which the storage enclosure 2 is to be situated. Although hanging cords 44 are shown in FIGS. 1 and 2 as being attached to each eyelet 46, it is within the scope of the invention to use selected eyelets 46 for suspension, such as, for example, to two eyelets 46 on a pair opposed strips 40. As further seen in FIGS. 1 and 2, the hanging cords 46 may be vertically oriented such as cord 44 a in FIGS. 1 and 2 or oriented at any angle less than vertical, such as shown by cord 44 b. The upper ends (not shown) of the cords 44 are suspended on mechanical elements (not shown) attached to structure above the storage enclosure 2 in which it is positioned. The cords 44 can be suspended on any structure, such as to rafters, beams, ceilings, and other members. The mechanical elements (not shown) may comprise brackets, threaded hooks, loops, or other suitable attachment elements. The function of the hanging cords 44 is to support the frameless enclosure 2 and erect and maintain it in its storage configuration creating storage compartment space 4 a. The length, angle, and position of the hanging cords 44 define the shape of the frameless storage enclosure 2 to meet a range of configurations from the fully erected shape in FIG. 1 to any modified shape, such as shown in FIG. 6 to accommodate its positioning under sloped roof 50 and the like. The dimensions of the height, width and length of the sides 6 may be varied in manufacture of the enclosure 2 to modify its volumetric capacity and the like.
Referring now to FIGS. 1, 2, 3, 5, and 6 the ventilation filter pocket 60 of the invention is best shown. The filter pocket 60 may be situated at least two locations on the enclosure 2 to create an air flow, such as on front panel 10 and side panel 8. As seen in FIGS. 1-3, 5 and 6 the filter pockets 60 are selectively provided in the side panels 8, front panels 10 and rear panel (not shown.) at a particular position to provide sufficient air flow interiorly through the enclosure. The filter pocket 60 is attached to the side panels 8, front panel 10, and rear panel 14 overlying hole 62 (FIG. 7) passing through either of the panels 8, 10, or 14 as previously described. The pocket 60 has a flat outer layer 64 having bottom and side edge portions 66 attached to side panel 8 and forming a filter receiving compartment 68. The layer 64 has an exterior hole 70 creating an air flow in conjunction with hole 62. A conventional filter 80 is removable and insertable into the compartment 68 being interposed between holes 62 and hole 70. The filter 80 is of a known material and design that permits air flow and inhibits the passage of dust and insects into storage compartment 4 a. The layer 64 creates an opening 82 with the wall 4 at the tope of pocket 60 to allow the insertion and removal of filter 80. A pivotal flap 84 is connected to the pocket 60 and overlays the pocket to close the opening 82 or open flap 84 for to insert or remove filter 80. A Velcro tab 86 may be used to secure the flap 84 in its closed position.
An identification pocket 90 is attached to front wall 10 to allow insertion of a written or pictorial sheet designation of the items being stored in the frameless storage enclosure 2 for informational purposes. The front wall 92 of the identification pocket 90 is preferably transparent to view the identification sheet within the pocket 90. The structure of pocket 90 generally corresponds to filter pocket 60, except for its intended contents and absence of flow-through holes.
