Description:
BACKGROUND OF THE INVENTION
Building toys have long offered hours of recreation to children. Lately building toys have been recognized as valuable in educating the child and stimulating creativity. The curious child is keenly interested in the workings of physical phenomena about him. Manipulative experiences with building toys give the child a measure of satisfaction to these curiosities. Building toys allow the child to experiment in and see differences in size, shape and color, all of which help him to understand spatial relationships and achieve technical mastery. Limited only by imagaination, children take apart and put together building modules in an endless array of configurations, each in the nature of a new discovery or invention, resulting in the type of imaginative play called creativity.
Further, toy building modules assist in instilling confidence in the child. As he builds up a structure from the modules, then takes it down to build yet another, he feels he has acquired a degree of control over his immediate environment. As the child grasps physical concepts, he is able to grasp mental concepts and thus gains confidence to tackle even more formidable problems.
A number of building modules have been developed which allow a child to indulge in these creative learning experiences. For example, see U.S. Pat. No. D208,789 to Kuhn.
SUMMARY OF THE INVENTION
The invention relates to toy building modules primarily for children, for the erection of structures of varying sizes and shapes according to the imagaination of the child, allowing experimentation and creativity on the part of the child. The building module has a base having a curvilinear surface such as a conical or generally hemispherically shaped shell which defines on one side a diametric plane. Equally spaced about the periphery of the shell are a plurality of legs. The legs are preferably orientated perpendicular to the diametric plane and pass through a portion of the base or shell. One end of each leg terminates in proximity to the diametric plane and the opposite end of each leg extends outwardly from the shell. The legs of one toy building module are interconnectable with the legs of another toy building module. Means are provided whereby the toy building modules may be connected with the concave portions of the base of each module in facing relationship to each other to define a closed structure, or with the concave portions of the base of each building module successively aligned and facing the same direction. The modules may be stacked with the legs in alignment or, alternatively, they may be staggered, thus enabling the child to construct a wide variety of structures of differing shapes and sizes.
An object of the invention is to provide a toy building module interconnectable with other building modules to form a structure. A second object is to provide such a building module interconnectable in a variety of different ways to thus provide a wide choice of structures which may be erected. A third object of the invention is to provide such a building module having a base with a generally curvilinear surface interconnectable with other such building modules and having the curvilinear surface selectively opposed to or in alignment with the curvilinear surface defined by other toy building modules. Further objects of the invention will become apparent upon the following description.

DESCRIPTION OF PREFERRED EMBODIMENTS
Referring to the drawings, there is shown in FIGS. 1 through 3 a first embodiment of a toy building module, indicated generally at 10, according to the present invention. Building module 10 has a base 11 having a curvilinear surface shown to be generally hemispherical in shape, although it is understood that the base could be conically shaped or some other decorative shape such as pyramidal. The generally hemispherical base of shell 11 of building module 10 is upwardly open as shown in FIG. 2, and has an outer or upper peripheral edge 12 defining a diametric plane 14. Shell 11 has a convex outer side extending from the diametric plane uniformly decreasing in diameter away from said diametric plane about an axis and converging at a point on said axis. As shown in FIGS. 1 and 2, hemispherical shell 11 is hollow whereby diametric plane 14 is imaginary, and is the plane usually defined by planar intersection of a sphere. Shell 11 could optionally be formed more or less of a hemisphere but preferably is constituted as a hemisphere which permits assembly of two modules into a complete sphere.
Shell 11 has a plurality of tubular legs 15 secured thereto each having a portion extending outward from the convex side of shell 11 and a portion extending inward through the concave portion thereof. Legs 15 include four legs equally spaced about the shell 11 having inward ends 16 attached to the outer peripheral edge 12 of shell 11. Legs 15 are orientated generally in perpendicular relationship to diametric plane 14 and each has an end 17 extending through the shell 11 and outwardly therefrom, terminating approximately in coplanar relationship with the outermost portion of the convex side of shell 11.
Legs 15 of toy building module 10 are equipped with means for interconnection with the legs of similar toy building modules, enabling the erection of diversified structures. Referring to FIG. 3, the upper end 16 of leg 15, or the end located proximate the diametric plane 14, is open, as at 19, thus to provide a recess to snugly receive an outwardly projected member extended from one end of a leg located on another toy building module. The lower portion 17 of leg 15, or that portion extending away from the convex face of shell 11, has a longitudinally extended finger or projection 20. The projection 20 is of a transverse dimension or diameter reduced sufficiently to be snugly and removably insertable in a recess of the size of recess 19, at the opposite end of leg 15, located on a leg of another toy building module.
Illustrated in FIGS. 4 through 6 is a second toy building module, indicated generally at 22, according to the present invention. Toy building module 22 is the same in all respects as the first embodiment 10 of the toy building module except that the interconnecting means on the legs are disposed in reverse relationship to the hemispherical shell as compared to those on toy building module 10 of the first embodiment. Toy building module 22, as shown in FIGS. 4 and 5, has a generally hemispherical shell 23. The circular, upper peripheral edge 24 of shell 23 defines a diametric plane 26 facing the concave face of hemispherical shell 23. Four parallel, equal length, legs 27 are equally spaced around the periphery of shell 23. Each leg 27 has a portion 28 extending through the concave face of shell 23 and terminating proximate to the diametric plane 26. Each leg 27 also has a portion 29 extending outward from shell 23 from the convex face thereof and terminating in approximately coplanar relationship with the outermost segment of the convex face of shell 23.
Legs 27 of toy building module 22 are equipped with means for interconnection with legs of similar toy building modules thus to enable erection of diversified structures. Referring to FIG. 6, the upper portion 28 of leg 27, or that portion extending through the concave face of shell 23 and terminating proximate the diametric plane 26, has a longitudinally extended finger or projection 31. Projection 31 is of a transverse dimension or diameter reduced sufficiently to be snugly insertable in a recess of the size of the recess 19 of leg 15 of the toy building module 10 of the first embodiment. At the opposite end of leg 27, or that end extending from the convex face of shell 23, is an opening or recess 32 having a diameter of sufficient size to snugly receive a projection or finger of the size of the projection 31 located on a leg of another toy building module. It is thus apparent that the only difference between the toy building module 22 of the second embodiment and the toy building module 10 of the first embodiment is the orientation of the interconnecting means on the legs.
In FIG. 7 there is shown an elementary structure 35 illustrating several of the many ways in which toy building modules of the embodiments described may be interconnected. The toy building modules are interconnectable with the convex face of the shell facing either down or up and with one or more of the legs of a given toy building module in alignment with and interconnected with one or more of the legs of another toy building module. A pair of spaced apart toy building modules 36, 37 form the base of structure 35, each being of the type having projections 38 on legs 39 extending away from the concave face of the toy building modules 36, 37. Each toy building module 36, 37 is orientated with the convex face of the hemispherical shell directed downward.
Assembled to the toy building module 36 is a third toy building module 41 of the same embodiment, having the recessed portion of its legs 42 on that portion of the legs 42 extending outward from the convex face of the hemispherical shell and engaging the projections 38 of the legs 39 on toy building module 36.
A fourth toy building module 44 is assembled to the other base module 37. The toy building module 44 is the type having recesses 45 of the legs 46 located in the portion of the leg 46 proximate to the diametric plane of the hemispherical shell of the toy building module 44. In the assembled relationship shown, the projections 38 of the leg 39 on base module 37 engage the recesses 45 of the legs 46 on the module 44. On the module 44, the convex face of the hemispherical shell is facing upward, thus forming a complete sphere in assembled relationship to the toy building module 37, as shown in FIG. 7.
A fifth toy building module 49 is assembled to the closest adjacent legs of the toy building modules 41 and 44. Module 49 is of the type having legs 50 with recesses 51 on the portion of the legs 50 located proximate to the diametric plane of the hemisphere of the module 49. The upwardly extended projections 53 on the legs 42, 46 of the modules 41, 44 engage the recesses 51 of the legs 50 on the building module 49, two of the legs of each module 41, 44 engaging two of the legs of the upper module 49. It is apparent that many additional modules could be assembled to the structure 35 in a great diversity of fashions to form more extensive structures. The endless variety of structures which thus may be erected are limited only by the imagination of the child.

DESCRIPTION OF PREFERRED EMBODIMENTS
Referring to the drawings, there is shown in FIGS. 1 through 3 a first embodiment of a toy building module, indicated generally at 10, according to the present invention. Building module 10 has a base 11 having a curvilinear surface shown to be generally hemispherical in shape, although it is understood that the base could be conically shaped or some other decorative shape such as pyramidal. The generally hemispherical base of shell 11 of building module 10 is upwardly open as shown in FIG. 2, and has an outer or upper peripheral edge 12 defining a diametric plane 14. Shell 11 has a convex outer side extending from the diametric plane uniformly decreasing in diameter away from said diametric plane about an axis and converging at a point on said axis. As shown in FIGS. 1 and 2, hemispherical shell 11 is hollow whereby diametric plane 14 is imaginary, and is the plane usually defined by planar intersection of a sphere. Shell 11 could optionally be formed more or less of a hemisphere but preferably is constituted as a hemisphere which permits assembly of two modules into a complete sphere.
Shell 11 has a plurality of tubular legs 15 secured thereto each having a portion extending outward from the convex side of shell 11 and a portion extending inward through the concave portion thereof. Legs 15 include four legs equally spaced about the shell 11 having inward ends 16 attached to the outer peripheral edge 12 of shell 11. Legs 15 are orientated generally in perpendicular relationship to diametric plane 14 and each has an end 17 extending through the shell 11 and outwardly therefrom, terminating approximately in coplanar relationship with the outermost portion of the convex side of shell 11.
Legs 15 of toy building module 10 are equipped with means for interconnection with the legs of similar toy building modules, enabling the erection of diversified structures. Referring to FIG. 3, the upper end 16 of leg 15, or the end located proximate the diametric plane 14, is open, as at 19, thus to provide a recess to snugly receive an outwardly projected member extended from one end of a leg located on another toy building module. The lower portion 17 of leg 15, or that portion extending away from the convex face of shell 11, has a longitudinally extended finger or projection 20. The projection 20 is of a transverse dimension or diameter reduced sufficiently to be snugly and removably insertable in a recess of the size of recess 19, at the opposite end of leg 15, located on a leg of another toy building module.
Illustrated in FIGS. 4 through 6 is a second toy building module, indicated generally at 22, according to the present invention. Toy building module 22 is the same in all respects as the first embodiment 10 of the toy building module except that the interconnecting means on the legs are disposed in reverse relationship to the hemispherical shell as compared to those on toy building module 10 of the first embodiment. Toy building module 22, as shown in FIGS. 4 and 5, has a generally hemispherical shell 23. The circular, upper peripheral edge 24 of shell 23 defines a diametric plane 26 facing the concave face of hemispherical shell 23. Four parallel, equal length, legs 27 are equally spaced around the periphery of shell 23. Each leg 27 has a portion 28 extending through the concave face of shell 23 and terminating proximate to the diametric plane 26. Each leg 27 also has a portion 29 extending outward from shell 23 from the convex face thereof and terminating in approximately coplanar relationship with the outermost segment of the convex face of shell 23.
Legs 27 of toy building module 22 are equipped with means for interconnection with legs of similar toy building modules thus to enable erection of diversified structures. Referring to FIG. 6, the upper portion 28 of leg 27, or that portion extending through the concave face of shell 23 and terminating proximate the diametric plane 26, has a longitudinally extended finger or projection 31. Projection 31 is of a transverse dimension or diameter reduced sufficiently to be snugly insertable in a recess of the size of the recess 19 of leg 15 of the toy building module 10 of the first embodiment. At the opposite end of leg 27, or that end extending from the convex face of shell 23, is an opening or recess 32 having a diameter of sufficient size to snugly receive a projection or finger of the size of the projection 31 located on a leg of another toy building module. It is thus apparent that the only difference between the toy building module 22 of the second embodiment and the toy building module 10 of the first embodiment is the orientation of the interconnecting means on the legs.
In FIG. 7 there is shown an elementary structure 35 illustrating several of the many ways in which toy building modules of the embodiments described may be interconnected. The toy building modules are interconnectable with the convex face of the shell facing either down or up and with one or more of the legs of a given toy building module in alignment with and interconnected with one or more of the legs of another toy building module. A pair of spaced apart toy building modules 36, 37 form the base of structure 35, each being of the type having projections 38 on legs 39 extending away from the concave face of the toy building modules 36, 37. Each toy building module 36, 37 is orientated with the convex face of the hemispherical shell directed downward.
Assembled to the toy building module 36 is a third toy building module 41 of the same embodiment, having the recessed portion of its legs 42 on that portion of the legs 42 extending outward from the convex face of the hemispherical shell and engaging the projections 38 of the legs 39 on toy building module 36.
A fourth toy building module 44 is assembled to the other base module 37. The toy building module 44 is the type having recesses 45 of the legs 46 located in the portion of the leg 46 proximate to the diametric plane of the hemispherical shell of the toy building module 44. In the assembled relationship shown, the projections 38 of the leg 39 on base module 37 engage the recesses 45 of the legs 46 on the module 44. On the module 44, the convex face of the hemispherical shell is facing upward, thus forming a complete sphere in assembled relationship to the toy building module 37, as shown in FIG. 7.
A fifth toy building module 49 is assembled to the closest adjacent legs of the toy building modules 41 and 44. Module 49 is of the type having legs 50 with recesses 51 on the portion of the legs 50 located proximate to the diametric plane of the hemisphere of the module 49. The upwardly extended projections 53 on the legs 42, 46 of the modules 41, 44 engage the recesses 51 of the legs 50 on the building module 49, two of the legs of each module 41, 44 engaging two of the legs of the upper module 49. It is apparent that many additional modules could be assembled to the structure 35 in a great diversity of fashions to form more extensive structures. The endless variety of structures which thus may be erected are limited only by the imagination of the child.
