Abstract
Abstract A toy karate device having a separable board or other element made from two mating separable pieces held in end to end relationship by a retainer which permits separation of the two mating pieces when the board is struck with the hand to simulate the board being broken in two by a karate chop. The board is provided with a support such as a block placed under each end and is struck in the center while the board is lying horizontally on the blocks. The retainer is a strip of cardboard or other yieldable material, or may be an adhesive or magnetic device.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
221 words
A simulated karate device comprising: A. a separable element to be struck with a human hand; B. said element comprising a pair of mating pieces, each piece having an irregular edge which interfits with a similar irregular edge on the opposite piece, each of the irregular edges comprising a series of outwardly extending projections alternately defining therebetween a series of inwardly extending depressions, the projections of one piece extending into the depressions in the opposite piece when the pieces are assembled together, in such manner that the projections of one piece overlap the projections of the other piece in the longitudinal dirEction; C. each piece having a transverse recess in its respective irregular edge passing through the outwardly extending projections; D. the recess in each edge being in alignment with the recess in the opposed edge of the mating piece when the two mating pieces are assembled together in edge to edge relationship; and E. yieldable retaining means simultaneously extending through the transverse recesses in the outwardly extending projections on both pieces to key the two pieces together; F. said retaining means having sufficient strength to releasably join together the mating pieces but being sufficiently yieldable to permit separation of the pieces when the separable element is struck with the hand to create the illusion of breaking a single continuous element.
