Description

BOOKLET

BACKGROUND

The present invention relates to booklets and more specifically, to loose-leaf booklets.

Booklets of information may be used in extreme environments, such as by workmen. For example, workman operating mobile material handlers, such as extending boom aerial platforms, use booklets showing load charts. These load charts are used to inform the operator of limits on the weight the machine may lift at various angles and various boom extension lengths. The operator may be working under severe temperature conditions and may be wearing gloves. Moreover, the operator may need to pay attention to operating the machine at the same time he is locating information in the booklet .

Known booklets include bound booklets and spiral loose-leaf booklets. Bound booklets fix the inner edges of the pages together. Thus, the pages must be flexible to lie flat against one another. Flexible pages do not hold up well under abuse and are difficult to handle with gloves and under extreme circumstances. Spital loose-leaf booklets work better with stiff pages, but the pages tend to get caught on the spirals and may break, particularly in extreme cold.

Accordingly, there is a need for a booklet that is easy to use by the operator under severe conditions. The booklet should withstand the extreme environment of the outdoors and a great amount of abuse. The pages should lie flat and be easily flipped even with a gloved hand. The information in the booklet should be readable by the operator even if the book becomes scratched. For vehicle applications, the booklet should be securely fastened to the dash.

SUMMARY

The disadvantages of the prior art are overcome to a great extent by the present invention, which provides a booklet having a base, a plurality of pages having at least one mounting portion and a plurality of display portions.

The mounting portions are hinged with respect to the display portions. The mounting portions have page engaging members, and the base has base engaging members . The base engaging members are configured to engage the page engaging members to attach the mounting portions to the base and to provide for the mounting portions to move with respect to the base to allow the display portions to move to a greater extent than the display portions would move without such movement of the mounting portions, to allow the display portions to lie more flat against one another when the pages are turned.

In one aspect, the base engaging members include pins mounted on the base, and the page engaging members include holes formed through the mounting portions, the pins extending through the holes. The holes may be elongated.

In another aspect, the base engaging members and the page engaging members include at least one protrusion and at least one recess, the protrusion engaging the recess. The protrusions and recesses may be on either the mounting portions or the base, or on both.

In another aspect, the mounting portions are hinged with respect to the plurality of display portions by at least one hinge member. The hinge member may include at least one hinge sheet and/or at least one hinge wire.

In yet another aspect, the display portion includes a display portion hinge edge and the mounting portion includes a mounting portion hinge edge, at least one hinge sheet extending between the mounting portion hinge edge and the display portion hinge edge to form a hinge therebetween. The respective hinge edges of said hinged-together mounting portion and display portion may be of substantially the same length. The hinge sheet may be substantially the same length as the hinge edges of the hinged-together mounting portion and display portion to hinge together those portions along substantially their entire hinge edge lengths.

In another aspect, the hinge sheet includes a mounting portion engaging portion, the engaging portion being engaged with the hinged-together mounting portion. The mounting portion is a sheet having a mounting sheet surface, the hinge sheet engaging portion is an area of a sheet surface of said hinge sheet, and that area is adhered to said mounting sheet surface. The adhered area extends over less than the entire mounting sheet surface.

In still another aspect, a second display portion includes a second display portion hinge edge, at least one hinge sheet extends between the hinged-together display portion and the second display portion hinge edge to form a hinge therebetween.

In another aspect, a second mounting portion includes a second mounting portion hinge edge, at least one hinge sheet extends between the hinged-together second display portion and the second mounting portion hinge edge to form a hinge therebetween.

One aspect of the invention relates to a special purpose page usable in combination with other, like pages in situations where outdoor conditions, high weathering, temperature extremes, excessive wear, dirty conditions, high pressure washing actions, possible chemical spills, grease, common solvents, and general rough handling and the like are to be encountered, and wherein the page or pages must survive and remain legible on a long term basis and even be turnable by gloved hands, to assure that safety warnings or other critical instructions are always available and accessible. The pages may be mounted on large, construction or maintenance equipment such as cranes, forklift vehicles, backhoes, military vehicles and other equipment. Besides having high wear characteristics, the pages are designed to remain in such position as has been selected by the operator and to have no tendency to turn of their own volition.

It is an object of the present invention to provide a booklet .

It is a further object of the invention to provide a loose-leaf booklet.

It is another object of the invention to provide a booklet that is easy to use under severe conditions.

It is yet another an object of the invention to provide a booklet having the foregoing advantages and that may withstand the extreme environment of the outdoors and a great amount of abuse .

It is still another object of the invention to provide a booklet having the foregoing advantages and having pages that will lie flat and be easily flipped even with a gloved hand.

It is a further object of the invention to provide a booklet having the foregoing advantages and wherein the information in the booklet is readable by the operator even if the book becomes scratched. It is yet a further object of the invention to provide a booklet having the foregoing advantages and wherein, for vehicle applications, the booklet is securely fastened to the dash.

Refer now to FIG. 1 through 8 of the drawings, there being shown a booklet, generally designated by reference numeral 10, according to a preferred embodiment of the present invention. Booklet 10 includes a base 12 (FIG. 7) and pages, generally designated by reference numeral 14. The pages 14 have mounting portions, generally designated by reference numeral 80, and display portions, generally designated by reference numeral 20. In the embodiment shown, the pages 14 include pages 51, 52, 53, 54, 55, 56, 57, 58, 59, and 60, having separate corresponding display portions 20 and sharing mounting portions 82 and 84. The mounting portions 80 are hinged with respect to the display portions 20.

The mounting portions 80 and the base 12 are configured to hold the mounting portions 80 to the base 20 while allowing the mounting portions 80 to slide up and down with respect to the base 20 in the direction of the arrows 83 and 85. As shown in FIGS. 2 and 3, this mounting is effected by way of base engaging members, in the form of a pair of mounting pins 90 attached to the base 20 and extending through page engaging members, in the form of two corresponding mounting holes 70 formed in the mounting portions 82 and 84. The holes 70 should be sized to allow the mounting portions 80 to move up and down so the display portions 20 of the pages 14 may move to a greater extent than the display portions 20 would move without such movement of the mounting portions 80, to allow the display portions 20 to lie more flat against one another when the pages 14 are turned, as shown in FIG. 3.

Each display portion 20 of the illustrated embodiment includes a front face 24 and a back face 26. The faces 24 and 26 have top edges 23 and bottom edges 21 connected at the outside by outer edge 22. The top and bottom edges are connected at the insides by an inner edge 28 for the front face 24 and by an inner edge 29 for the back face 26. In the embodiment shown, the edges 28 and 29 are hinge edges adjacent hinge sheet 30 as described below with respect to FIG. 4. The tabs 40 are positioned along the outer edges 22 to allow the user to select a desired page 14. Preferably, the tabs 40 are sized and shaped and located at staggered positions so that they may be easily and individually selected by a gloved hand. The tabs 40 may be affixed to the display portions 20 as shown in FIG 5. The tabs 40 are shown at edges 22, but could also be positioned at edges 21 and/or 23. Page numbers or other identifiers may be marked on the tab 40, which may be manipulated by the user to turn the page .

In alternate preferred embodiments shown in FIG. 6, the mounting of mounting portions 180 is effected by way of protrusions engaging recesses. The protrusions and recesses may be positioned on the mounting portions and/or the base. As shown at the left of FIG 6., a protrusion in the form of a tab 192, is part of and extending from the mounting portion 180 to engage the recess 192 of the base 112. Also on the left side, a protrusion 198 is part of and extending from the base 112 to engage the recess 178 of the mounting portion 180. As shown at the right of FIG 6., a two protrusions in the form of a tabs 194 and 196 are part of and extending from the mounting portion 180 to engage the recesses 174 and 176 of the base 112. The recess and protrusion engaging members are sized and positioned to allow for movement of the mounting portion 180 in the direction of arrows 85 as discussed above with respect to mounting portion 80.

Refer to FIG. 4 which shows a partial cross-section of the display portions 20 and mounting portion 82 of pages 55 and 56. The dimensions of the component parts have been exaggerated to show schematically the construction of an embodiment of the pages of the booklet 10. Each display portion 20 includes a front face 24 and a back face 26. In the FIG. 4, the back face 26 of page 55 is flat against the front face 24 of page 56. The front faces 24 include an outer front reinforcing sheet 118 affixed, such as by lamination, to a front printed sheet 170. The printed sheet 170 can be read through, and is protected by, the reinforcing sheet 118. The front printed sheet 170 is affixed, such as by gluing to a front adhesive sheet 132 which is affixed, such as by lamination to an inner front reinforcing sheet 160. The back faces 26 include an outer back reinforcing sheet 110 affixed, such as by lamination, to a back printed sheet 120. The printed sheet 120 can be read through, and is protected by, the reinforcing sheet 110. The back printed sheet 120 is affixed, such as by gluing to a back adhesive sheet 130 which is affixed, such as by lamination to an inner back reinforcing sheet 140. The inner front reinforcing sheet 118 and the inner back reinforcing sheet 140 are held together, such as by adhesive or double sided tape 150 and 152. The edges of the component may be interconnected at outer edges 22 of display portions 20. In the illustrated embodiment, the outer front and back reinforcing sheets 110 and 118 are formed as one piece and interconnected by member 111 along edge 22. Also in the illustrated embodiment, the front and back adhesive sheets 132 and 130 are formed as one piece and interconnected by member 131 along edge 22. The members 111 and 131 may extend along the entire length of edge 221. The mounting portion 82 may be similarly constructed as an inner and/or outer faces of the display portions 20.

Hinge sheets 34 extend between and overlap and engage the inner edges, hinge edges, 28 and 29 of respective adjacent display portions and adjacent display and mounting portions. The overlapping engaging portions 32 of hinge sheets 34 may extend over an area less than the area of the inner or outer surfaces of display portions 20 and mounting portions 80. The respective hinge edges of said hinged-together mounting portion and display portion may be of substantially the same length. The hinge sheet may be substantially the same length as the hinge edges of the hinged-together mounting portion and display portion to hinge together those portions along substantially their entire hinge edge lengths.

The construction illustrated allows separate assembly 5 of the outer reinforcing sheets with the printed sheets on the one hand, and the inner reinforcing sheets and adhesive sheets of the other hand. The reinforcing sheets are relatively stiff to withstand abuse and weather resistant. Preferably the information on the printed sheets remain 0 readable even if the reinforcing sheets become scratched.

The adhesive sheet should be compatible for adhering to the printed sheet . The hinge sheets should be relatively flexible for easy turning of the pages, yet tough to 5 withstand abuse. The construction is shown by way of example, other constructions may be used. For example, the hinge could be formed by thinning the relatively stiff material forming all or a portion of the display portions and/or the mounting portions, such as by forming a so-called o living hinge 30. Moreover, tough wire, such as piano wire could be used, rather than a sheet material, to make a hinge 30.

Refer to FIGS. 7 and 8 which show a base 12 for the 5 booklet 10. The base 12 has a recess or opening 15 for receiving the mounting portions 80 of the pages 14. The mounting portions 80 have two slots 70 oriented generally transversely with respect to the hinge 30. Pins 90 include bolts 91 and nuts 92 and extend through each of the slots 70 to loosely engage the mounting portions 80 and extend through the holes 62 to engage a downwardly extending mounting flange 63 of the base 12. In the embodiment shown, the flange 63 defines the opening 15. Spacers 17 and washers 18 are be provided on the pin and may be added, removed or otherwise adjusted to obtain the desired degree of looseness for the number of mounting portions 80 engaged. The base 12 has a table surface to provide a resting position for the display portions 20. The base is mounted to a dash 16 of a vehicle, such as in the cab of a telescopic handler, by bolts 17.

Refer to FIGS. 9 and 10 wherein an alternate page construction is shown. The pages 254 and 255 each include an individual base portion 280, corresponding to each display portion 220 to form separate leafs for each page. Also, the hinge sheet 230 extends over only a portion of the surface of the display portion 220. Also the display portions are longer than the mounting portions, allowing a larger display area for the booklet 210 relative to the length of the opening 15 of the base 12.

Refer now to FIGS. 11 - 15. It is contemplated that a plurality of these special pages or leaves will be used as a group to form a booklet having from two to four or even twenty or more leaves. Such a booklet 312 is shown in FIG. 11 and includes, as an example, three structurally identical leaves 310A, 310B, and 310C on which different printed information, such as charts, maps or instructions may be presented. Note that the leaves, are separate, unjoined to one another, supplementable to allow addition of new intervening leaves, and can carry information on both front and rear surfaces .

Referring now to FIG. 12, each leaf, such as leaf 310A or 310B, has an information portion 314 wherein information may be printed so as to be visible at the front and rear surfaces 315 and 316, respectively, of the leaf. Each leaf also has a binding portion 317 interconnected to the information portion 314 by a special purpose hinge 318. The binding portion 317 has apertures 320 to allow the leaves to be joined as a booklet 312 as best shown in FIG. 11, using suitable fasteners such as screw style fasteners 322 and 322A, which have shafts 324 and 324A, respectively, each shaft having an outer diameter smaller than that of the apertures 320. It is desirable that the apertures 320 be of larger diameter than the shafts 324 or 324A so that leaves located near the center of the booklet 312 have sufficient space to move outward in direction 325 so as to allow the information portion 314 of leaf 310A to cleanly fold leftward or rightward and still lie flat on top of the adjacent leaf. In order to fold flat as described, the binding portion 317A of leaf 310A does need to move slightly outward in direction 325 relative to the adjacent pages 310B and 310C.

Referring now to FIG. 13, each leaf, such as leaf 310B, utilizes a central, highly flexible but highly tear resistant hinge layer defined by a sheet 340 which both reinforces the leaf and acts as a hinge. It has been found that a sheet of fiber reinforced, flexible and tear resistant material is highly effective as the hinge sheet. The hinge sheet may be formed of various materials and shall be effective for the purpose. For example, high density polyethylene material such as that now sold under the trademark Canvex is useable. Cross laminated polyethylene material is also suitable and one type of such material sold under the Rufco trademark has been found useful . It is not essential that the hinge material be formed of a solid material. For example, a mesh style material woven of, among other things, vinyl or polyethylene, can be substituted. For example, such a mesh material having apertures of approximately 1/32 inch of less is useful. A vinyl mesh fabric now available under the Windbeater trademark is useful as the hinge sheet, and mesh material weights ranging between ten ounces and sixteen ounces can be used. Another mesh type material useable with the invention is eight mil woven polyethylene material .

Alternatively, polyester coated fabric of even laminated vinyl fabric in the ten ounce to fourteen ounce weight class can be used as the hinge sheet.

For some applications, a spun olefin type material of the type now sold under the trademark Tyvek can be effective as the hinge sheet. It has been found that Tyvek material having a thickness of about 0.007 inch and a weight classified as twenty pound material is suitable for most scenarios to which the booklet 312 will be exposed, but use of heavier or lighter weight Tyvek is within the scope of the invention. It is noted that Tyvek is at times used in the printing industry as a surface on which outdoor banners of the type used in political campaigns are printed but is not believed to have been used as a hinge.

In addition, it should be understood that other reinforced materials having high wear but readily bendable and flexible materials such as, by example, various synthetic fabrics (including ripstop nylon) may at times be used and are within the purview of the invention. The stiffness and tear resistance of the hinge sheet 340 can be raised or lowered by increasing or decreasing, respectively, the thickness or weight of the material .

The hinge sheet which comprises layer 340 is cut to have a width slightly less than the distance between the edges 342 and 344 (FIG. 12) of the leaf 310B. The sheet defining layer 340 has a length about a half inch less than the distance between edges 346 and 348 of the leaf 310B for reasons described below. The edge 350 of the sheet 340 is positioned inwardly from leaf edge 348 to allow adequate space to receive the shoulder portion 352 of an identification tab 354 provided for the convenience of the user of the booklet.

The leaf 310B includes relatively hard, abrasion resistant outer layers 360 and 362, which are preferable formed as a single sheet and folded along edge 364 to overlie and protect the hinge layer 340 and the informational printing which will be described hereafter. The fold area is the most exposed and handled edge of the leaf, and the continuous fold gives extra protection against separation or damage of the layers 360 and 362. Preferably the outer layers 360 and 362 are formed of a commercially available transparent or nearly transparent polycarbonate material having a thickness of approximately 0.007 inch, and all informational messages are preprinted on the innermost side 360A and 362A of each layer 360 and 362, respectively, so as to best protect the messages. It is known to print messages on polycarbonate material . Such polycarbonate material is extremely long wearing, abrasion resistant, stain resistant to most chemicals, resistant to weathering and ultraviolet radiation and capable of withstanding the rough handling commonly encountered at job and construction sites. The polycarbonate material is not, however, capable of the repeated bending and folding which is required of a leaf like that described herein and would quickly fatigue and break if forced to function as a hinge.

After printing the message on the backside 360A and 362A of layers 360 and 362, respectively., of the polycarbonate material, it is sometimes aesthetically helpful to apply a layer of white pigment which will underlie the message, that is be positioned on the side of the message closest to the hinge layer 340 to avoid any bleed through or visibility of the message on the opposite side of the leaf 310B. After placement of any needed white pigment as described, a layer of adhesive is applied to the surfaces 360A and 362A and to any polycarbonate interconnecting the surfaces 360A and 362A, such as 353 (FIG. 14) .

When it is desired to use index tabs 354 with the leaves, the edge 348 of the leaf 310B may be die cut to create a narrow slot 368 through which the index tab may be inserted. The tab 354, as best seen in FIG. 12, has a shoulder 352, and the slot 368 is sized to allow passage of the narrow portion 369 of the tab through the slot 368 but retains the shoulder 352 behind the foldline 353, which joins surfaces 360A and 362A.

Preferably the tab 354 should be as long lasting as the leaf 310B, and is configured like a miniature version of the leaf 310B, but without any hinge layer 340. That is, the tab is preferably cut from polycarbonate material with the printed information being applied to the inner surfaces 380 and 382 of the polycarbonate to shelter the printing from the elements, the polycarbonate being folded over upon itself along a fold line 370 analogous to the fold line 353 of the leaf 310B as described herein. Before such folding, the printing on the surfaces 380 and 382 on each side of the foldline 370 of the tab may be coated with a background layer of pigment to enhance readability and appearance of the tab printing. An adhesive layer is applied to the index tab over the pigment, and the left and right mirror image halves 384 and 386 of the tab are then folded over along fold line 370 and permanently adhered to each other. If desired, the printing of the white pigment^' and the application of the adhesive may be done in a single step by using a pigmented adhesive. The finished tab 354 is inserted in slot 368 as described above.

When the hinge layer 340 has been placed on the adhesive with a spacing as illustrated in FIG. 12, there will be sufficient space around the periphery of the hinge layer to allow the adhesive on the polycarbonate to surround the outer edges 349, 350 and 351 of the hinge layer and strongly bond the polycarbonate surfaces permanently together. The extra spacing between foldline 353 of the polycarbonate and edge 350 of the hinge layer (Figs. 12 and 14) avoids overlapping of the hinge layer 340 and the shoulder 352 of the tab and produces a leaf 310B having a generally regular thickness .

Referring now to FIG. 13, polycarbonate panels 380 and 382 are fixed to the hinge layer 340 by adhesive applied to the undersides 380A and 382A of the panels and will typically have the same thickness and composition as the polycarbonate forming layers 360 and 362. A pigment may be applied to the inner sides 380A and 382A to enhance their appearance. The panels 380 and 382 each have their edges 381 and 383, respectively, spaced from the edges 363 and 364, respectively, of polycarbonate layers 360 and 362 by a gap 385. A highly satisfactory hinge has been obtained with the gap 385 (FIG. 12) having a width of approximately 0.06 to 0.08 inch, allowing the information portion 314 of each leaf 310B to be easily folded or swung between first position 390 (FIG. 13) to second position 392 or third position 394, each displaced slightly more than ninety degrees from first position 390. The described hinge structure is capable of great numbers of swinging movements between the described positions 392 and 394 without appreciable wear. In addition the described structure has been designed so that the weights of the described materials result in a leaf that once turned to second or third position, has a high stability and no inclination to return to the first position 390 of its own volition. This characteristic is advantageous because in the use described, the operator of a heavy crane or the like generally needs to keep both hands on the controls, and while consulting the information in the booklet, will have no free hand to hold a page in a particular position. It is also noted that the combination of the flexible hinge layer 340 and the adhesively attached armored layers 360 and 362 cooperate to provide a strong, flexible leaf, while also allowing exceptional hinging performance.

The above description and drawings are only illustrative of preferred embodiments of the present invention, and are not intended to limit the present invention thereto. For example, one embodiment shown has a set of ten display portions hinged together and hinged to two mounting portions, and another embodiment shown has one display portion hinged to one mounting portion, however the invention is not limited to these arrangement. More than one set of pages could be used in one base, provided that sufficient movement of the mounting portions is allowed for the display portions of the pages to turn. Moreover, more or less than ten pages may be used with more or less than two mounting portions. Also, for example, the base of the booklet is shown configured for mating to a vehicle, but may be configured for mating to other structure or for portable use. Any subject matter or modification thereof which comes within the spirit and scope of the following claims is to be considered part of the present invention.
