DESCRIPTION OF THE PREFERRED EMBODIMENT

As is illustrated in FIGS. 1-3, the present invention is embodied in a ball-like toy, indicated generally at 10, which includes central disc 12 having an annular configuration. The disc is formed with an outer circular ring 14 and an inner circular ring 16 separated by an annular wall portion 15; inside the inner ring is a thin circular wall 18 having a central aperture therethrough. The rings 14 and 16 have a thickness slightly larger than the thickness of the annular wall portion (see FIG. 3).

As is shown in FIG. 3, the toy 10 utilizes eight identical hollow ungulas or wedges 20, so only one wedge will be described in detail for the sake of brevity. Each wedge 20 has an interior reinforcing rib in the shape of a triangular wall 22 defined by its base side 24, its height side 26 and its hypotenuse side 28 as illustrated in the diagram of FIG. 10. The height side 26 of the wall 22 is integral with the midline of the solid arcuate wall 30 which has a base edge integral with the edge of a semi-circular end wall 32; the base side 24 of wall 22 is integral with the midline of the semi-circular end wall 32. Extending between its base side 24 and its hypotenuse side 28, the interior wall 22 is formed with a generally U-shaped slot 34, the inner part of which is enlarged to receive the disc ring 14. The opening of the slot 34, at the point between the two sides 24 and 28, engages the disc ring 16. As is apparent from FIG. 3, the open edge of the wedge 20 is defined by a semi-elliptical outline 36.

To assemble the ball-like construction 10 from the components of FIG. 3, the eight wedges 20 are disposed on the disc 12 by placing each U-shaped slot 34 on the disc 12. The assembly is made by alternating the facing surfaces for the wedges 20; thus, the first, third, fifth and seventh wedges have their surfaces reversed with regard to the respective surfaces of the second, fourth, sixth and eighth wedges. With such an arrangement, one wedge has its semi-circular end wall 32 shutting the semi-circular end wall 32 of one adjacent wedge while the semi-elliptical edge 36 abuts the semi-elliptical edge 36 of another adjacent wedge. During assembly, each wedge 20 is mated to the disc 12 and not to other wedges 20, so there is no problem in inserting the final eighth wedge; the rings 14 and 16 on the disc 12 separately interconnect each wedge to the disc 12.

Upon assembly, the ball-like construction 10 has the general outline of a square when observed in a plan view (see FIG. 2). The result is an odd shaped ball 10 that will roll only about two transverse axes, i.e., the north-south axis and east-west axis of FIG. 2. Rolling of the odd shaped ball 10 is easily accomplished since it has its center of gravity located at the exact center of symmetry which coincides with the center of curvature of each wedge of the construction so no kinetic energy is consumed in raising the center of gravity and because the construction is made from light weight plastic as by injection molding. To further enhance its aesthetic appeal, the wedges 20 have different colors so they may be assembled with a variety of designs.

It is also possible to assemble the eight wedges 20 into shapes other than that shown in FIG. 1. For example, FIGS. 25 and 26 utilize the same components of FIG. 3 in forming a windmill 230; the eight wedges 20 are mounted on the disc 12 in the same manner with the surface 32 of one wedge abutting the semi-elliptical edge 36 of the adjacent wedge. The central aperture in the central wall 18 of disc 12 permits a string to be inserted through the entire assembly to make a pinwheel 230 that will spin in the wind. Of course, the eight wedges 20 may be arranged in various combinations as by varying the abutting surfaces 32 and 36 in different sequences.

All of the shapes to be described below utilize the same structure of the disc member 12, so that the following descriptions will be directed to that structure which differs from FIGS. 1-3. Thus, FIG. 4 shows a plan view of a generally triangular ball-like construction 40 made of six wedges 41, each with a 60.degree. central angle, and an interior wall or reinforcing rib 42 (see FIG. 9) having the same structure as rib 22 in FIG. 10 but having different angles therefrom. The interior rib 42 has sides 44, 46 and 48 attached to the interior of the walls of wedge 40 in the same manner as the sides 24, 26 and 28 of the rib 22 in FIG. 3.

FIG. 5 shows a plan view of a generally pentagonal ball-like construction 50 made of ten wedges 51, each with a central angle of 36.degree. and an interior wall or reinforcing rib 52 (see FIG. 17) having the same structure as rib 22 in Fig. 10 but different angles therefrom. The interior rib 52 has sides 54, 56 and 58 attached to the interior of the walls of the wedge 51 in the same manner as the sides 24, 26 and 28 of the rib 22 in FIG. 3. The wedges 51 are mated in pairs along their adjacent end walls (such as 32 in FIG. 3) and adjacent pairs are then mated along their adjacent hypotenuse sides 58.

It is now apparent that the cylindrical wedges forming the ball-like construction need not be identical but only that the mating surfaces between adjacent wedges be the same. Thus in FIG. 6 there is shown a rhombic ball-like construction 100 made of four wedges 41 and four wedges 61, each having a rib 42 as are described above; each wedge 61 has an interior wall or reinforcing rib 62 (see FIG. 11) having the same structure as rib 22 in FIG. 10 but different angles therefrom. The interior rib 62 has sides 64, 66 and 68 attached to the interior of the walls of the wedge 61 in the same manner as the sides 24, 26 and 26 of the rib 22 in FIG. 3. As is shown in FIG. 6, the wedges 41 are each mated in pairs along adjacent their hypotenuse sides 48; the wedges 61 are each mated in pairs along their adjacent hypotenuse sides 68. The four pairs of wedges are then alternately mated along their adjacent end walls such as wall 32 in FIG. 3.

FIG. 7 shows a plan view of a generally hexagonal ball-like construction 110 made of twelve wedges 61 having a central angle of 30.degree. as seen in FIG. 11 and as described above. The wedges 61 are mated in pairs along their adjacent end walls (such as end wall 32 in FIG. 3) and each pair are then mated along their adjacent hypotenuse sides 68.

FIG. 8 shows a plan view of a generally trapezoidal ball-like construction 115 made of four wedges 61 and four wedges 41. The wedges 41 are mated in pairs along their hypotenuse sides 48 and the pairs are then mated along adjacent end walls (such as end wall 32 in FIG. 3); the wedges 61 are mated in pairs along their hypotenuse sides 68 and the pairs are then mated along adjacent end walls (such as end wall 32 in FIG. 3). Then the two end walls of the pairs of wedges 41 are mated to the adjacent end walls of the pairs of wedges 61 to complete the trapezoidal configuration.

FIG. 12 shows a plan view of a ball-like construction 130 having an irregular outline formed by a upper half portion of rectangular configuration and a lower half portion of a half of a hexagon. The upper half portion is made of four wedges 20, each having a central angle of 45.degree. as shown in FIG. 10 and as described above. The lower half portion is made of six wedges 61, each having a central angle of 30.degree. as shown in FIG. 12 and as described above. The four wedges 20 are mated in pairs along their hypotenuse sides 48 and the pairs are then mated along adjacent end walls 32 as shown in FIG. 3. Four of the six wedges 61 are mated into pairs along their end walls (such as end walls 32 in FIG. 3) and the remaining two wedges 61 are mated, one on each hypotenuse side 68. The two remaining end walls of the wedges 61 are then mated with the two remaining end walls 32 of the wedges 20 to complete the irregular outline.

FIG. 13 shows a plan view of a ball-like construction 140 having an irregular outline formed by an upper half portion of rectangular configuration identical to the upper portion of FIG. 12 so that it is not being described again. The lower half portion includes two partial spherical hollow wedges 120, each having a central angle of 90.degree. . Each wedge 120 (see FIG. 13A) has an interior reinforcing rib or wall 122 having two sides 124 and 128 at right angles to each other and an arcuate side (not shown) integrally joined to the mid-line of a solid arcuate wall 130 similar to the rib joined to the arcuate wall 30 in FIG. 3. The arcuate wall 130 has a base edge integral with the edge of a semi-circular end wall 132. Extending from its side 124 to its other side 128, the interior wall 122 is formed with a generally U-shaped slot 134. While the components of wedge 120 are similar to those of wedge 20, the angles are all at 90.degree. so that while the side 128 is not a hypotenuse it may be considered a hypotenuse side to compare with 28 in FIG. 3; the open edge of the wedge 120 is defined by a semi-circular outline.

The wedges 120 are mated to each other along their adjacent sides 136 and then each end wall 132 is mated to adjacent end walls 30 of the upper rectangular portion to complete the irregular outline.

FIG. 14 shows a plan view of a ball-like construction 150 having an irregular outline formed by an upper portion of a partial triangle and a lower portion of two partial spherical wedges 121. The upper portion includes four wedges 41 mated in pairs along their hypotenuse sides 48 and then mated along adjacent base sides 46. The lower portion includes the two wedges 121 which are similar to the spherical wedges 120 but differs therefrom in that each wedge 121 has a central angle of 60.degree. while the wedge 120 has a central angle of 90.degree. . The two end walls (similar to 132 in FIG. 13A) are mated to the adjacent base sides 46 of the upper portion to complete the irregular outline.

FIG. 15 shows a plan view of a ball-like construction 160 having an irregular outline formed by an upper portion which is half of a hexagon identical to the lower portion of FIG. 12. The lower portion of FIG. 15 has a hemispherical outline and is identical to the lower portion of FIG. 13 so it will not be described further. The irregular outline is completed by mating the exposed end walls of the wedges 61 to the adjacent end walls 132 of the wedges 120.

FIG. 16 shows a plan view of a ball-like construction 170 having an irregular outline formed by an upper portion of trapezoidal configuration and a lower portion of hemispherical outline identical to the lower portion of FIG. 13 which will not be described further. The upper portion includes two wedges 41 mated along their hypotenuse sides 48 and two wedges 61 mated along their hypotenuse sides 68; the adjacent end walls of the mated wedges are then mated to each other to form the trapezoidal outline. The two end walls 132 of wedges 120 are then mated to the remaining two end walls of the trapezoidal outline to complete the irregular outline.

The triangular reinforcing rib 72 in FIG. 18 includes a base side 74, a height side 76 and a hypotenuse side 78, which sides enclose a central angle of 24.degree. and a base angle of 66.degree. . Wedges formed according to FIG. 18 may be combined to form an irregular hexagonal outline similar to that shown in FIG. 19. Such an irregular hexagonal outline would include six wedges from FIG. 18 using their central angle of 24.degree. and six wedges 51 shown in FIGS. 5 and 17 using their central angle of 36.degree. , alternately arranged in pairs similar to the arrangement shown in FIG. 19.

FIG. 19 shows a plan view of a ball-like construction 180 having an irregular hexagonal outline formed from six wedges 20 mated in pairs along their hypotenuse sides 28 and six wedges 81 mated in pairs along their hypotenuse sides 88. As is shown in FIG. 21, the interior rib 82 for the wedges 81 includes a base side 84, a height side 86 and a hypotenuse side 88, which sides enclose a central angle of 15.degree. and a base angle of 75.degree. . The mated pairs of wedges 20 and 81 are alternately arranged with their adjacent end walls (such as 32 in FIG. 3) mated together to complete the irregular hexagonal outline.

FIG. 20 shows a plan view of a ball-like construction 190 having a regular polygonal outline with twelve sides formed from twenty-four wedges 81 mated in pairs along their hypotenuse sides 88 and then mated along their adjacent end walls (such as 32 in FIG. 3) to complete the regular twelve-sided polygonal outline.

FIG. 22 shows a plan view of a ball-like construction 200 having an irregular polygonal outline formed from eight wedges including four wedges 20, two wedges 41 and two wedges 61. The upper portion of the outline includes the four wedges 20 arranged in a rectangular configuration identical to the upper portion of FIG. 12 so that it is not being described further. The lower portion includes the two wedges 41 and the two wedges 61 arranged in a trapezoidal configuration identical to the upper portion of FIG. 16 so that it is not being described further. The above wedges are mated in pairs along their hypotenuse sides and the upper and lower portions are mated along the exposed end walls of adjacent wedges to complete the irregular polygonal outline.

FIG. 23 shows a plan view of a ball-like construction 210 having an irregular polygonal outline formed from ten wedges including two wedges 41 and eight wedges 61. The wedges 41 are arranged in a pair by being mated along their hypotenuse sides 48 and the wedges 61 are arranged in pairs by being mated along their hypotenuse sides 68. The end walls (such as 32 in FIG. 3) of the pairs of wedges 61 are mated together leaving two end walls exposed, which are then mated to the adjacent end walls of the two wedges 41 to complete the irregular polygonal outline.

FIG. 24 shows a plan view of a ball-like construction 220 having an irregular polygonal outline formed from ten wedges including four wedges 20 and six wedges 61. The wedges 20 are mated into two pairs along their hypotenuse sides 28. The wedges 61 are mated into three pairs along their hypotenuse sides 68; two pairs of wedges 61 are mated together along their adjacent end walls (such as 32 in FIG. 3) leaving a first pair of exposed end walls spaced from each other and a second pair of exposed end walls spaced from each other. A first pair of wedges 20 have their exposed end walls 32 mated to the first pair of exposed end walls of wedges 61. A second pair of wedges 20 have their exposed end walls 32 mated to the second pair of exposed end walls of wedges 61, thus completing the irregular polygonal outline.

In the above described outlines, it should be noted that except for the windmill 230 in FIGS. 25 and 26, the assemblies are made by mating a hypotenuse side (i.e. the opened side) only with another hypotenuse side and by mating an end wall with another end wall. The solid arcuate wall (such as 30 in FIG. 3) is obviously not mated with any other wall. This mating arrangement is possible because the radius of curvature (such as 32 in FIG. 3 and as 132 in FIG. 13A) is the same on all the disclosed cylindrical wedges and spherical wedges. The ball-like constructions are not limited to those described above because the various types of disclosed wedges may be utilized to construct other types of shapes. For example, all of the wedges shown in FIGS. 3, 4 and 7 have been combined into ten different constructions.

The above ball-like constructions have the unusual result of being able to roll, rock and waddle, which make them attractive to children as well as adults. They are easy to assemble and to take any one apart, which may be accomplished by squeezing gently the two half portions in both hands while prying the thumbs apart outwardly.

While the wedges may be assembled on the disc in the ways described above, it is also possible that assembly may be made in a variety of the ways, such as mating some end walls with some hypotenuse sides. The resulting outline would satisfy the curiosity and imagination of a child in constructing an odd shaped outline.

Inasmuch as the present invention is subject to many modifications, various and changes in detail, it is intended that all matter contained in the foregoing description or shown in the accompanying drawings, shall be interpreted as illustrative and not in a limiting sense.
