The present invention concerns a recreational display form, more particularly to a three-dimensional form and a blank for making the form.
Three-dimensional forms are useful for mathematical modeling and for predicting crystal structures and such. The model forms may also be useful for recreational purposes such as toys and puzzles. Often, the forms are generated from blanks, which involve several folding and adhesion steps to produce the final form. The blanks are often of a complex design and involve folding steps that may be ergonomically disfavored. Several such designs are illustrated as follows:
The aforesaid designs, however, suffer from a number of disadvantages. Weissman's design includes a blank with multiple shaped flaps located on all sides of the blank. A number of slots appear to be used to connect the flaps thereinto. Disadvantageously, for the form to be constructed the slots and the flaps have to be accurately aligned, which may be difficult if one of the flaps is distorted. Moreover, manufacture of the blank may involve precision cutting to enable accurate connection of the slots and the flaps. A number of rubber bands are required to hold the form together by a complicated interconnection to a number of panel slits and which would require a high level of manual dexterity, which may be inappropriate for children. Miller's design appears to be designed for interfitting multiple elements and involves the use of a complex template with multiple folds. The form, once constructed is a polyhedral with filleted edges, clefts and webbing, which appear to be used for interfitting the forms, and may be inappropriate for displaying images thereon.
Thus there is a need for an improved three dimensional form for displaying images.
The present invention reduces the difficulties and disadvantages of the previous designs by providing a novel blank that is used to make a three-dimensional form. The blank is made of a collectable recreational card, such as hockey or football cards and the like, and includes a novel arrangement of folds and images, so that a user can quickly and easily construct the form. Advantageously, the form can be assembled using ergonomically favorable folding movements and using simple adhesive strips to maintain the form. Multiple forms can be fitted together to form a polyhedral display form on which a user can display multiple favorite sporting figure images, teams images and the like. This is advantageously achieved without the need for complex design features. For additional versatility, the form may also be used as an education tool such as a puzzle, which may aid the development of color and pattern recognition skills. The blank is of a simple design, which does not require precision cutting and is manufactured using inexpensive and readily available starting materials such as cardboard. Moreover, securing flaps are located on only a select number of blank edges and are merely folded over to enable construction of the form.

Referring now to
The first rhomboid panel 14 has a first edge 17, a second edge 18 and a third edge 20. Another fold line 22 bisects the panel 14 and the together with the fold line 18, divides the first rhomboid panel 14 into two triangular panels 24, 26.
The second rhomboid panel 16 is connected to the first rhomboid panel 14 along the fold line 18. The second rhomboid panel 16 includes first, second and third side edges 28, 30, and 32. A third fold line 34 bisects the panel 16 and together with the fold line 18, defines a second pair of triangular panels 36, 38.
A first securing flap 40, a second securing flap 42 and a third securing flap 44 are connected respectively to the first, second and third edges 17, 18, 20 of the first rhomboid panel 14. Although three securing flaps are illustrated in this embodiment, it is to be understood that one or two securing flaps located on one of the rhomboid panels would also work without deviating from the scope of the invention. The first, second and third securing flaps 40, 42, 44 include respective first, second and third flap fold lines 46, 48, 50 along the first, second and third edges 17, 18, 20 of the first rhomboid panel 14. Typically, the first, second, and third edges 17, 18, 20 and the three side edges 28, 30, and 32 are substantially equal in length.
Each of the securing flaps 40, 42, 44 includes a first securing flap edge 52, a second securing flap edge 54 and a third securing flap edge 56.
Typically, the first and second securing flap edges 52, 54 are shorter than the third securing flap edge 56. The first and second securing flap edges 52, 54 are angled inwardly towards each other such that when the blank 12 is laid on a flat surface, the second securing flap edge 54 of the second securing flap 42 and the first securing flap edge 52 of the third securing flap 44 define an obtuse angle 58 therebetween. The first securing flap edge 52 of the first securing flap 40 and the second securing flap edge 54 of the second securing flap 44 extend to an intersection 60 therebetween so that the first and second securing flap edges 52, 54 form a linear edge portion 62. Typically, the securing flaps 42, 44, 46 have substantially equal width. The fold lines 18, 22, 34 are substantially of equal length and define the triangular panels which are four equilateral triangles 24, 26, 36, 38.
In an important aspect of the present invention, images 64, 66, 68, 70 are adhered to each of the triangular panels 24, 26, 36, 38. Typically, the images are part of a single sheet of image material, which are secured to the surface of the card. The images 64, 66, 68, 70 maybe complete recreational images such as sporting figures or they may be a portion of an image. The images may have a picture of a sporting figure and information such as player statistics thereon. The images 64, 66, 68, 70 may each be different, which increases the versatility of the three-dimensional form 10.
In the embodiment illustrated, the images 64, 66, 68, 70 are located on one side of the sheet 72, the other side 74 being blank. The blank side of the sheet 74, once the form is constructed faces the inner void of the form 10. One skilled in the art will recognize that both sides of the blank can be covered with an image or portions of an image. This alternative feature increases the versatility of the display form.
As best illustrated in
Adhesive strips 76 are connected to each of the securing flaps 42, 44, 46 along substantially the entire length thereof. In the embodiment illustrated, the adhesive strips 76 are protected by a removable strip (not shown), which is removed before the form 10 is assembled. One skilled in the art will recognize that although adhesive strips are used, other types of securing media, such as VELCRO™, magnetic strips and the like could be used without deviating from the scope of the invention. Moreover, the adhesive strips 76 may be used to temporarily construct the three-dimensional form 10 such that after the user is finished displaying the images, the form 10 can be dismantled quickly and easily, to enable transport without excessive bulk. The adhesive strips 76 connect the securing flaps 40, 42, 44 to the respective side edges 28, 30, and 32 of the second rhomboid panel 16. One skilled in the art will recognize that if one securing flap is present on the first rhomboid panel 14 of the blank 10, it connects to one of the side edges of the second rhomboid panel 16.
The first and second rhomboid panels 14, 16 are folded about the fold line 18 towards each other so that the panels 14, 16 are generally orthogonal to each other. The three securing flaps 42, 44, 46 are folded inwardly about their fold lines and the first, second and third edges 17, 18, 20 and are positioned generally orthogonal to the their respective rhomboid panels 14, 16. The securing flaps 42, 44, 46 are folded towards the side edges 28, 30, 32 of the second rhomboid panel 16. The second pair of triangles are folded about the third fold line, so that first, second and third securing flaps 42, 24, 46 are adhered, using the adhesive strips 76 to the side edges 28, 30, and 32 of the second rhomboid panel 16. Once constructed, the form 10 includes the four triangular panels with the images facing outwardly of the form 10.

The blank 10 of the present invention may also be used in kit form together with an instructions sheet for folding the blank 12 to produce the form 10. The kit may include one or many cards, which the collector collects and may be used to construct the polyhedron 78.
While a specific embodiment has been described, those skilled in the art will recognize many alterations that could be made within the spirit of the invention, which is defined solely according to the following claims.
