MILLER g g g ATTORNEYS PATENTEDAUB 81912 SHEET 2 [IF 3 PATENTEB 8 sum 3 BF 3 FIG4 50 62 40 30 FIG-6 THREE DIMENSIONAL PUZZLE BACKGROUND OF THE INVENTION The most common type of jigsaw puzzle is the two dimensional type in which a series of complementarily configured interlocking puzzle segments are assembled to produce a planar surface which is usually imprinted with a pictorial representation. While this type of puzzle is undoubtedly the most widely used, it will be apparent that the decorative effects obtainable with the completed puzzle are limited to two dimensional images. Additionally, more experienced puzzle assemblers may feel a lack of challenge with a two dimensional puzzle since the principal way of increasing the complexity of the puzzle is to increase the number of puzzle segments.
US. Pat. No. 2,987,318 shows a second type of puzzle in which the puzzle segments are curved so that upon attachment to a core member a three dimensional object is formed. While this approach provides more interesting images, it will be seen that again, only the surfaces of the puzzle segments are actually used.
A third type of jigsaw puzzle is shown in US. Pat. No. 1,964,007. In puzzles of this type, layers of puzzles are stacked to produce three dimensional objects. Of course, only the top surface of the uppermost layer and the outermost edges of the underlying layers are visible and the uppermost surfaces of the lower layers add nothing to visual effect obtained.
SUMMARY or THE INVENTION The present invention provides a three dimensional puzzle in which layers of interlocked puzzle segments are stacked in superimposed relationship in a supporting tray having a base and upstanding side walls. Each of the layers is provided with one or more voids of geometric or irregular shape which relate to the voids contained in the other layers to produce a pleasing or stimulating visual effect.
It will thus be seen that a puzzle is provided which, through the use of multiple layers having interrelated voids formed therein, not only provides more interesting visual effects but presents a greater challenge to more experienced puzzle assemblers.
Of course, if it is desired to render assembly less difficult various aid to assembly may be provided. For example, each of the segments in each layer may be provided with identifying markings to distinguish it from segments of other layers. Additionally, a series of starter frames may be provided for each layer with the openings through each frame of progressively larger size toward the top of the stack.
It will be seen that by forming voids through the puzzle layers, a more intricate design is produced than where merely the top surface of one layer and the edges of underlying layers are utilized, and the decorative effects obtained by positioning portions of the underlying layers beneath the voids formed in the layers same time, for less experienced puzzle assemblers, the puzzle can also be simplified to some extent.
It will also be seen that the voids through the layers may be so formed as to provide in the assembled puzzle one or more display compartments for mounting any of a variety of objects such as gems and other stones, insects, or other articles. Thus, the'puzzle of the present invention may have a utilitarian as well as an entertainment and decorative aspect.

FIG. 2 is a plan view of typical layer of interlocked puzzle segments, the uppermost layer being shown for purposes of illustration;
FIG. 3 is an exploded perspective view of the supporting tray, layers of puzzle segments and a transparent cover member; I
FIG. 4 is a cross-sectional view taken on line 4--4 of FIG. 6; 9
FIG. 5 is a partial bottom plan view with portions of superimposed layers broken away for purposes of clarity; and
FIG. 6 is a plan view of the puzzle layers and supporting tray.
DESCRIPTION OF THE PREFERRED EMBODIMENTS With reference to FIGS. 3 and'4, it will be seen that a three dimensional puzzle in accordance with the thereabove may be enhanced by suitable color compresent invention includes a supporting tray 10 having a planar base 1 1 and upstanding side walls 12. Mounted within the tray 10 in stacked, laminar relationship are a plurality of layers of interlocked puzzle segments. Bottom layer 20, formed of puzzle segments 21, only some of which are shown, is mounted in the lowermost position immediately upon the base 1 l of the tray 10. Layer 20 is provided with a series of voids 22 which, as shown, may be of rectangular configuration and through which a pattern 23 imprinted on portions of base member 11 situated beneath the voids 22 is visible. Any desired pattern may be utilized and one simulating an interlocked puzzle design is shown for purposes of illustration.
Immediately above layer 20 a second layer 30 is positioned with layer 30 being comprised of a series of interlocked puzzle segments 31. Voids 32, which are of different configuration than voids 22 are formed in layer 30 and cover a greater area than the voids 22 so that portions of layer 20 are visible through the voids 32.
Superimposed on layer 30 are a third layer 40 and a fourth layer 50, each formed of a plurality of interlocked puzzle segments 41 and 51, respectively, and provided with voids 42 and 52 therethrough. Openings 42 are larger than and concentric with openings 32, while openings 52 are larger than and concentric with openings 42, so that portions of each underlying layer are visible through the voids in the layers thereabove. While the openings 32, 42 and 52 are shown as of substantially the same configuration, it will be apparent that they may be varied to obtain the particular aesthetic effect desired as well as the particular con figuration of display case if the assembled puzzle is intended for this use.
Superimposed on the uppermost layer 50 is a cover sheet 60 of transparent material and, as seen in FIG. 1, the entire assembly may be mounted in a suitable frame 61. With continued reference to FIG. 1, it will be seen that not only is the patterned portion 23 of the base 11 visible through the openings 22 but portions 24 of layer 20, portions 33 of layer 30, and portions 43 of layer 40 are also visible.
To enhance the decorative effect obtained with the three dimensional puzzle of the invention, the various layers may be differently colored to produce blends or contrasts between visible portions of adjacent layers. For example, a cathedral effect might be obtained through the use of alternating layers of black and white. Additionally, both surfaces of each layer may be colored, for example, one side black and one side white, or any desired combination, so that the puzzle may, at the option of the assembler, be assembled with either side up.
It will also be noted from FIG. 1 that the puzzle of the present invention may have utilitarian as well as decorative and entertainment aspects. Thus the voids formed in the superimposed layers may be utilized for display purposes for exhibiting gems and other stones, insects, jewelry and the like. For purposes of illustration insect shaped jewelry, as at 62, is positioned in the upper portion of the puzzle, and this may be accomplished by adhesively securing the display item to the tray surface, as at 63 (FIG. 4), or by providing the item with a mounting pin, as at 64 (FIG. 1) which may be inserted in the edge of any one of the layers to further enhance the three dimensional effect.
As noted above, the degree of complexity obtainable with a puzzle produced in accordance with the present invention should readily satisfy even the most experienced puzzle assembler. However, if it is desired to provide a puzzle of a lesser degree of difficulty, various modifications may be made as an aid to the assembly process. Thus, as seen in FIG. 5, the bottom surface of each of the layers may be provided with some means for identifying the layer in which each puzzle segment should be positioned in the final assembly. This may take the form, for example, of color coding or any other convenient indicia for identifying the segments from each layer, such coding or indicia being diagrammatically represented by the cross hatching 25, 35, 45 and 55 shown on the lower surfaces of the segments 20, 30, 40 and,50, respectively. With this assembly aid provided, the assembler merely segregates the segments formed from each layer into separate groups and thus appreciably narrows the number of pieces being worked with at any one time.
With reference to FIG. 6, a further aid to assembly will be described. As seen in FIG. 6, in addition to the superimposed layers 20, 30', 40' and 50, a series of stacked frames 70, 71, 72 and 73 are provided. Preferably, each frame has an opening therein smaller than the opening in the frame immediately thereabove and having internal dimensions complementary to the external dimensions of the layer of puzzle segments received therein in coplanar relationship therewith.
Thus, when utilizing the frames, preferably in connection with the identifying means shown in Fig. 5, the
first-frame 70 is inserted in the tray with its periphery engaged by the upstanding side walls 12 of the tray and the first layer 20' of puzzle segments is assembled within the frame. Upon completion of the layer 20' the second frame 71 having a slightly larger opening therethrough, is stacked on top of the frame and the second layer 30' is assembled within the opening in the frame 71. The same process isv then repeated with frames 72 and 73 to provide the completed puzzle,
substantially as shown in FIG. 1.
From the above it will be apparent that a three dimensional puzzle according to the present invention not only provides a puzzle for entertainment purposes, the degree of difficulty of assembly of which may be varied to provide a challenge to assemblers of varying degrees of experience, but through the use of variously colored, superimposed layers having voids of geometric or irregular configuration, a pleasing decorative effect is produced which may also serve the utilitarian purpose of a display case.
Turning now to FIG. 2 of the drawings, it will be noted that the puzzle segments 51, that is, those segments located at the periphery of a void, are provided with straight edges coinciding with this periphery. This illustrates one method by which the formation of small irregularly sized pieces, which could be easily lost. can be avoided in cutting the puzzle. Of course, in some instances an irregularly shaped void might be desired, in which case this expedient would be unnecessary.
While the forms of apparatus herein described constitute preferred embodiments of the invention, it is to be understood that the invention is not limited to these precise forms of apparatus, and that changes may be made therein without departing from the scope of the invention.
