Description




FIELD OF THE INVENTION




The present invention relates generally to storage cases for puzzles, and more particularly relates to portable cases also serving as puzzle workstations.




BACKGROUND OF THE INVENTION




The present invention relates to a puzzle caddy for facilitating assembly of the pieces of a jigsaw puzzle and for enabling the assembled or partially assembled puzzle to be stored and/or transported from place to place. One such exemplary device is disclosed in U.S. Pat. No. 4,436,307.




While many puzzle caddies have enjoyed much commercial success, they are not without their drawbacks. For example, many puzzle caddies have complicated structures for protecting the puzzle. Such puzzle caddies require significant amounts of manual labor to construct, resulting in lower productivity and higher cost. Similarly, components selected for constructing these devices often increase costs even further, and may require the manual installation of that component. Accordingly, there exists a need for a sturdy yet easily formed puzzle caddy having a low cost of production.




BRIEF SUMMARY OF THE INVENTION




In light of the above, it is a general aim of the present invention to provide an improved portable puzzle storage case that allows assembled and unassembled pieces to be stored or transported from place-to-place without disturbing the position of the pieces, and that is simple and cost effective to produce.




In that regard, it is a further object of the present invention to provide such a portable puzzle storage case that can be produced inexpensively and with minimal waste.




In accordance with these objects, the present invention provides a portable jigsaw puzzle storage board generally comprising an outer cover which encloses a sorting tray and a workstation therein. The workstation generally includes an assembly tray having an assembly board and a frame. The frame extends around at least part of the outer periphery of the assembly board, and is joined thereto by an integral hinge.




According towards more detailed aspects of the puzzle storage board, the assembly board has four sides, the frame extending around three of the four sides. Preferably, the hinge joins the assembly board and frame along the fourth, unframed, side of the assembly board. The frame includes a first strip connecting opposing second and third strips, the second and third strips being joined to the assembly board by integral hinges. A bottom surface of the frame is integrally joined to a top surface of the assembly board to form the integral hinge. Additionally, the workstation may further include a second assembly tray identical to the first assembly tray, each of the tray sized to hold a first standard size puzzle. The first and second assembly trays are positionable proximate each other along the unframed sides to form a combined assembly tray sized for a second standard size puzzle larger than the first standard size puzzle. Preferably, the assembly tray is formed of corrugated fiberboard.




In accordance with another embodiment of the present invention, a method of producing an assembly tray is provided. The method generally comprises the steps of providing an assembly board having a first half and a second half, cutting out an inner section of the first half to define an outer peripheral strip, scoring the assembly board at a boundary line where the first and second half meet, and attaching the outer peripheral strip to the second half to form a frame on the second half of the assembly board.




According to more detailed aspects of this embodiment, the attaching step includes folding the outer peripheral strip about the boundary line and toward the second half, and also includes applying an adhesive to one of the outer peripheral strip and the second half. Preferably, the cutting step and scoring step are performed substantially simultaneously. The scoring step defines integral hinges linking the second half of the assembly board to the outer peripheral strip. The cutting step may further include the step of cutting the inner section to form a sorting tray.




Other objectives and advantages of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

and a second sorting tray


52


.




The cover


30


generally comprises a top wall


31


and a bottom wall


33


which are connected by a side wall


32


. A second side wall


34


connects the bottom wall


33


to a flap


35


which selectively engages the top wall


31


to close or open the puzzle storage board


20


. The flap


35


generally includes at least one fastener


36


, which in the preferred embodiment comprises a pair of Velcro® tabs


36


. The fastener


36


allows the flap


35


to be selectively connected to the top wall


31

37


is employed to mechanically link the bottom wall


33


to the top wall


31


. In the illustrated embodiment, the bottom wall


33


has two opposing Velcro® strips


37


attached thereto which selectively engage corresponding strips on the top wall


31


. The first and second fasteners allow the top and bottom walls


31


,


33


of the cover


30


to supply a compressive force to the work station


40


and sorting tray


50


held therebetween. Preferably, the case


30


, workstation


40


, and sorting tray


50


are constructed of corrugated fiberboard which is sturdy, enough to transmit the compressive force, yet has sufficient ductility to prevent damage to puzzle pieces. The side walls are sized to be slighter smaller than the combined thickness of the stacked work station


40


and sorting tray


50


, including puzzle pieces, to assist inducing the above-noted compressive force.




As shown in

FIG. 3

, the workstation


40


generally comprises an assembly tray, and in the illustrated embodiment comprises a first assembly tray


41


and a second assembly tray


42


. Each of the first and second assembly trays


41


and


42


are generally identical, and their construction will be discussed in more detail herein with reference to

FIGS. 5-7

. Each tray


41


,


42


includes an assembly board


43


having a frame


44


extending a portion, preferably around three sides, of the periphery of the assembly board


43


. The working surface given by the assembly board


43


, for each of the first and second assembly trays


41


,


42


, is preferably sized at 19″×24½″, sized for a standard 500 piece puzzle. The trays


41


,


42


are framed only on three sides such that the open side of one tray may be placed adjacent the open side of the other tray to form a large work station


40


. The working surface of the combined assembly boards is 24¼″×38″, sized for a large puzzle containing 1,000 pieces.





FIG. 4

depicts an exploded view of the storage board of

FIG. 1

to reveal the assembly of the storage board, which will be described from bottom to top. The cover


30


is shown, partially cut away, and is opened to reveal the contents of the puzzle storage case


20


. The bottom wall


33


of the cover


30


is sized to correspond with the assembly trays


41


,


42


, and in the preferred embodiment has one storage tray


42


permanently affixed thereto, preferably by applying an adhesive to a bottom surface of the assembly tray


42


or the top surface of the bottom wall


33


. Within the frame


44


the assembly board


43


will carry assembled or partially assembled pieces


10


. To hold these pieces


10


in place, a sheet of anti-skid material


62


, such as a foam based material, is sized to fit within the unframed or working surface of the assembly board


43


, i.e., within the frame


44


, to engage the puzzle pieces


10


and hold them in place. The sorting tray


50


, which preferably comprises two flat boards or assembly trays


51


,


52


are preferably placed on top of the assembly


42


and the anti-skid sheet


62


, and are sized to be placed side by side and cover the same square area as the assembly tray


42


. The sorting trays


51


,


52


typically will hold the unassembled pieces


10


of the puzzle. Next, the other assembly tray


41


is placed on top of the sorting trays


51


,


52


, and more specifically directly on top of the unassembled puzzle pieces


10


. The assembly tray


41


will also typically included assembled puzzle pieces


10


, and thus another sheet of anti-skid material


61


is placed on the assembly board


43


within the frame


44


to hold the pieces


10


in place. Finally, in order to transport the entire puzzle storage case and workstation


20


, the top wall


31


will be folded over and placed on top of assembly tray


41


and its sheet of anti-skid material


61


. The flap


35


is then folded over to engage the top wall


31


and is held in place by fasteners


36


. As previously noted, the side walls


32


,


34


are sized such that when the cover


30


is closed, a compressive force is induced on the contents of the container to assist in holding the puzzle pieces


10


in place. Additionally, the second set of fasteners


37


may be engaged to temporarily fasten the bottom wall


33


to the top wall


31


. It will be noted that even though the puzzle pieces


10


on the sorting trays


51


,


52


are not in contact with any anti-skid material, the compressive force is sufficient to hold them in place without the need for such material.




Turning to

FIG. 5

, a cross-sectional end view of the puzzle storage board


20


is depicted. When in the closed position, the storage board


20


generally forms five layers. A first layer


71


comprises the bottom wall


33


of the cover


30


. The second layer


72


generally comprises a first assembly tray


41


which includes an assembly board


43


and frame


44


. The second layer


72


further includes a first sheet of anti-skid material, such as a foam-based material, which is sized to fit in the unframed area of the first assembly tray


41


. The first sheet


61


is generally thicker than the thickness of the frame


44


, although in a closed position the sheet


61


is compressed to hold the puzzle pieces in place and become generally flush with the top surface of the frame


44


. A third layer


73


generally comprises the at least one sorting tray


50


, and in the preferred embodiment comprises the first and second sorting trays


51


,


52


which are sized to both fit side by side such that their combined width match the width of the cover


30


and the puzzle storage board


20


. A fourth layer


74


comprises the second assembly tray


42


and a second sheet of anti-skid material


62


, which is sized and constructed identically to the second layer. A final fifth layer generally comprises the top wall


31


of the cover


30


. When in the closed position, the puzzle storage board


20


securely holds puzzle pieces therein, by virtue of the top and bottom wall applying a compressing force to the second, third and fourth layers contained between the walls. The sheets of anti-skid material


61


,


62


are slightly compressed to securely hold puzzle pieces within the assembly trays


41


,


42


. The loose pieces on sorting trays


51


,


52


are securely held in place by the clamping or compressive force between the sorting trays


51


,


52


and the bottom surface of the second assembly tray


42


. It has been found that enough compressive force is present and evenly distributed throughout the entire puzzle storage board


20


that a sheet of anti-skid material is not necessary to securely hold puzzle pieces in place on the sorting trays


51


,


52


.




In accordance with an aspect of the present invention, the frame


44


of the assembly trays


41


,


42


is also comprised of corrugated fiberboard and is integrally linked to the assembly board


43


. The frame


44


is generally rather wide, preferably in the range of 1 to 2 inches. It has been found that such a wide frame provides added security to the puzzle within the assembly board area


43


of the assembly trays


41


,


42


,




As will be described with reference to

FIGS. 6-8

, each of the assembly trays


41


,


42


is constructed in a novel manner. A starting board


45


comprises a first half


145


and a second half


245


divided by a boundary line BL. A first cut shown by dotted lines


46


is made in the first half


145


of the starting board


45


to leave an outer peripheral portion


146


. A second cut


47


is made to the cut out portion


150


(

FIG. 6

) to form a sorting tray


50


. Finally, a third score


48


is made on one side, the bottom side as shown in the figures, of the starting board


45


at the boundary line BL where the second half meets the outer peripheral portion. The outer peripheral strip


146


is then folded about the boundary line BL towards the second half


245


, the top side of the starting board


45


above the scores


48


forming an integral hinge


49


. Hence a bottom surface of the frame


44


and the top surface of the assembly board


43


define a hinge


49


integral to both structures. The outer peripheral strip


146


is then affixed to the second half


245


to form the frame


44


of the assembly tray


41


,


42


. Preferably, the outer peripheral strip


146


is adhesively attached, typically by glue, to the second half


245


of the starting board


45


, to form the assembly board


43


having a frame


44


, representing one of the assembly trays


41


,


42


.




The assembly trays


41


,


42


, and hence the sorting tray


50


, are thus formed in a single operation with a single sheet of material, and minimal waste is produced. The cuts and scores


46


,


47


and


48


may be formed by any well known means, although it has been found preferable to die cut the starting board


45


. By die cutting, a one time operation is made to make all the necessary cuts and scores. Therefore, the cutting steps and scoring steps are performed substantially simultaneously. Alternately, the cuts


46


,


47


can be made, and then the score


48


may be made to form the integral hinge


49


. Once the cutting and scoring steps are performed, the outer peripheral portion


146


may be attached to the second half


245


by applying an adhesive to one of the top surface of the outer peripheral portion


146


and the top surface of the outer edge of the second half


245


, and then the outer peripheral portion


146


is folded about the boundary line BL and score


48


. These steps of gluing and folding may also be performed substantially simultaneously. Importantly, by utilizing this method, there is no need to measure the outer peripheral portion


146


which forms the frame


144


, as it has been formed from a first half


145


that is substantially identical in size to a second half


245


as divided by the boundary line BL. Furthermore, the amount of glue needed, and the placement thereof, is easily determined and preprogrammed.
