Abstract

Abstract A toy comprising a hollow body member having a plurality of differently configurated openings and a plurality of block members corresponding in cross-sectional configuration to the openings. In a preferred embodiment the hollow body member is formed as two halves joined together by a spring means which permits the member to be "broken apart" to release the individual pieces. The holes in the hollow body member are located on plane defining portions which are in turn located adjacent curvilinear surface portions of said hollow body member. The block members can be used individually as molds or foodstuff cutters, stacking blocks, etc.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 116 words
A toy adapted for the introduction into and storage therein of individual block members and comprising an enclosed hollow body member having curvilinear surface portions and a plurality of plane defining portions adjacent one another, said plane defining portions being adapted to maintain said toy in stable resting positions on any suitable supporting surface and further having openings of different geometrical shapes formed therein communicating with the interior of said hollow body member, each of which is adapted only to accommodate the passage therethrough of a said block member which is of the geometrical shape corresponding thereto, and additional means to gain access to the interior of said hollow body for removing said block members therefrom.
Claim 2
Dependent Claim 116 words
A toy adapted for the introduction into and storage therein of individual block members and comprising an enclosed hollow body member having curvilinear surface portions and a plurality of plane defining portions adjacent one another, said plane defining portions being adapted to maintain said toy in stable resting positions on any suitable supporting surface and further having openings of different geometrical shapes formed therein communicating with the interior of said hollow body member, each of which is adapted only to accommodate the passage therethrough of a said block member which is of the geometrical shape corresponding thereto, and additional means to gain access to the interior of said hollow body for removing said block members therefrom.
Claim 3
Dependent Claim 121 words
A toy adapted for the introduction into and storage therein of individual block members and comprising a hollow body member having at least two separable parts each including guide means operatively associated in a manner for maintenance thereof in alignment during separation, said hollow body member further including adjacently positioned plane defining portions having openings therein for introduction therethrough of said block members, spring means attached to said parts in a manner to urge them together yet enable a sufficient separation therebetween so that the block members may be removed therefrom and handle means attached to each of said parts in an appropriate manner to be grasped in applying the force necessary to counteract said spring means in separating said parts.
Claim 4
Dependent Claim 121 words
A toy adapted for the introduction into and storage therein of individual block members and comprising a hollow body member having at least two separable parts each including guide means operatively associated in a manner for maintenance thereof in alignment during separation, said hollow body member further including adjacently positioned plane defining portions having openings therein for introduction therethrough of said block members, spring means attached to said parts in a manner to urge them together yet enable a sufficient separation therebetween so that the block members may be removed therefrom and handle means attached to each of said parts in an appropriate manner to be grasped in applying the force necessary to counteract said spring means in separating said parts.
Claim 5
Dependent Claim 26 words
A toy according to claim 2 wherein said guide means is formed by interfitting tubular extensions through which said spring means extends between said handle means.
