Primary Exa minerRichard C. Pinkham Assistant ExaminerR. T. Stouffer Att0rney-Wicks and Nemer [57] ABSTRACT A childrens amusement toy of a curved outer surface intersecting two parallel sides and a flat surface to form a solid body is disclosed. The body has a hollow center formed therein of a different configuration than the outer surface with a tunnel extending from the center to each side in a mutually perpendicular arrangement to allow children to rock within and upon the toy, climb through and upon the toy, and climb through and over the toy. The solid body is made to present a pleasing appearance through use of transparent surface material and a filling of multicolored foam material.
10 Claims, 5 Drawing Figures CHILDREN'S ROCKING AND CLIMBING TOY BACKGROUND This invention relates to toys, more particularly to childrens toys, and still more particularly to a type of childrens toy which may be played with, within, and upon.
An advantageous childrens toy is one which is versatile enough to allow a childs full use of his imagination, which is easy to fabricate, and which presents a pleasing appearance to the child. The present invention provides such a toy.
SUMMARY In summary, a preferred embodiment of the childrens toy of the present invention includes a rockerlike curved surface meeting a substantially flat surface and laterally limited by two parallel sides. A hollow center has access to each of the sides, the flat surface, and the curved surface through six tunnels extending to each from the six faces of a cube defining the hollow center. A child may then crawl into the toy or sit upon the flat surface of the toy and rock upon the rocker-like curved surface. A child may crawl within the toy and further rock upon the curved surface. A child may further rest the flat surface upon the ground and crawl through and over the childrens toy of the present invention and the curved surface thus turned upward.
The outside surfaces of the preferred embodiment of the childrens toy of the present invention are of transparent material, and the body of the toy is filled with separately colored plastic foam areas to present a colorful and pleasing external appearance to the child.
It is thus an object of the present invention to provide a novel childrens toy.
It is a further object of the present invention to provide a novel childrens toy which is versatile and allows the child to use his imagination.
It is a further object of the present invention to provide a novel childrens toy which presents a pleasing external appearance to the child.
DESCRIPTION OF THE DRAWINGS FIG. 1 shows a perspective view of the children s toy of the present invention illustrating the novel coloration and filling of the toy.
FIG. 2 shows a perspective view of the childs toy of the present invention showing the internal parts thereof in solid and the outline in phantom.
FIGS. 3 to 5 show various stages of construction of the childrens toy of the present invention.
DESCRIPTION In the figures, a preferred embodiment of the childrens toy according to the present invention, generally designated 10, is shown as including a curved rockerlike surface 12, having a peak 14 and first and second ends 16 and 18. A substantially flat surface 20 extends between ends 16 and 18 of curved surface 14, and parallel sides 22 and 24 arranged perpendicularly to the plane of surface 20 extend between the edges of surface 20 and curved surface 12 to close these surfaces and to define a solid body 26.
A hollow, designated 28, is defined within body 26 by a cube 30 having faces 32, 33, 34, 35, 36, and 37.
The manner in which the childrens toy of the present invention may be fabricated may now be explained. FIG. 3 shows a cube 30, which in the preferred embodiment includes 20 inch sides and 17 inch apertures 46, 47, 48, 49, 50, and 51 formed one to each of sides 32 37, respectively. Cube 30 may be formed of any light weight thin, durable material.
Next, as best seen in FIG. 4, tunnels 40 45 are securely attached to cube 30 within their respective apertures 46 51, and the entire assembly is stood upon tunnel 40 attached to face 32. As will be appreciated by those skilled in the art, cylindrical tunnels 40 45 may also be of various materials which are thin and yet strong.
Next,a sheet 54, best seen in FIG. 4, is placed over the partially completed cube 30 and attached tunnels 40 45 and a determination is made as to the proper angle at which the tunnels 41, 42, and 43 need be cut to conform and mount flush to curved surface 12.
.At this point the childs toy of the present invention is filled with a plastic foam as follows: The foam used is of a conventional type requiring the mixing of two components where, upon the mixing of these components, the foam displaces itself by approximately 30 times. Separate amounts of foam are prepared, colored, and poured into the open vessel comprising the sides 22 and 24 and curved surface 12. The poured foam thus partially filling body 26 of the childrens toy 10 of the present invention. By successively mixing differently colored amounts of foam and adding each amount to curved surface 12, surface 20, and sides 22 and 24.
Also, if an amount of foam is poured onto body 26 while the last foam added has not yet hardened, an edgewise fusion of colors takes place in which a different color may be created at 'the edges and in which a different texture may be created at the edges.
When foam added to fill body 26 is cured and dry, transparent surface 20 is secured to complete the solid body 26, and all surfaces are cut to provide access to their respective tunnels.
OPERATION Thus, children may orient toy 10 such that curved surface 12 is resting upon the ground, and may crawl within hollow 28 of toy 1 and thus rock within it. Children may also climb upon surface 20 of toy l0 and rock upon it. Children may further climb through'the various tunnels 40 45. Still further children may select substantially flat surface 20 to rest upon the ground and also climb through the various tunnels 40 45 and over curved surface 12 of toy 10. Additionally, children may rest toy on either side 22 or 24 and yet climb through, over, about, and around toy 10.
Thus, since the invention disclosed herein may be embodied in other specific forms without departing from the spirit or general characteristics thereof, the
embodiment described herein is to be considered in all respects illustrative and not restrictive.
