Abstract

Abstract A hoop toy related to the well-known "Hula Hoop" is constructed in the form of detachable arc segments, different numbers of which can be used by the player in fastening the entire hoop, allowing the hoop toy to be adjustable as to diameter, and further allowing complete disassembly for ease and convenience in storage and transportation. The fastening by which said arc segments are joined provide integrity and rigidity for the hoop and maintain the orientation of the entire hoop in a single geometric plane.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 234 words
A hoop toy which is easily disassemblable comprising a plurality of members in the form of arc segments and integral fastening means for removably connecting said members to each other; said fastening means comprising a projection integrally formed in one end of each member and a socket integrally formed in the other end of each member, said projections and sockets being flexible and elastic such that a larger diameter portion of the projection can, with momentary distortion of either or both of the projection and socket, be forcibly inserted through a smaller diameter portion of the socket, with said projection and socket thereafter returning to their original shapes; said socket being corrugated to form a plurality of circumferential ribs along its entire length and having an inwardly directed guide ridge extending longitudinally outwardly from the end of said socket proximal to said member along only a part of the length of said socket; said projection being corrugated from the end proximal to said member to form a plurality of circumferential ribs along a part of its length corresponding to the length of said socket and thereafter being tapered to its distal end, and having a guide groove along its entire length adapted to cooperate with said guide ridge; and wherein the interior surface portion of said socket and the exterior surface portion of said projection corresponding thereto closely conform as to dimensions and shape.
