Abstract
Abstract A toy karate device having a separable board made from two mating separable pieces held in end to end relationship. The board is provided with a support such as a block placed under each end. Each piece has an edge which mates with the edge of the other piece; each mating edge being irregular in the form of a series of longitudinally extending outwardly converging projections alternately defining therebetween inwardly converging depressions, the projections on one piece extending into the depressions of the opposite piece when the pieces are assembled together such that the projections of one piece overlaps the projections of the other piece, the configuration of the mated edges appearing as a broken board when the pieces are disassembled. Each irregular edge is provided with a retainer element which cooperates to releasably hold the two pieces together when the mating edges are mated; the cooperating retainer elements being releasable when the assembled board is struck in the center with a sharp blow while the board is lying horizontally on the blocks. The retainer is a yieldable material, or may be an adhesive or magnetic device.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
294 words
A toy karate device which can be reassembled repeatedly and rebroken to simulate the breaking of a solid continuous board with a human hand comprising: A. a separable elongated horizontal member comprising a pair of mating pieces joined together in end to end relationship, 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 longitudinally extending outwardly converging projections alternately defining therebetween inwardly converging depressions, the projections of one piece extending into the depressions of 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, the configuration of both irregular edges creating the visual appearance of the broken edges of an object that has been broken in two, when the two pieces are disassembled; B. means supporting opposite ends of the separable member a spaced distance from a fixed surface; C. first cooperative means attached to the irregular edge of one piece; and D. second cooperative means attached to the irregular edge of the other piece; E. said first and second cooperative means being of such construction that when placed in contact with each other they remain together and releasably attach the two mating pieces together; F. said cooperative means being separable from each other when the separable member formed from the assembled mating pieces is struck a sharp blow; G. each of said cooperative means having an outwardly facing surface which follows the contour of the adjacent portions of the irregular edge of the piece to which it is attached and of adjacent portions of the outwardly facing surface of the cooperative means attached to the opposite piece.

Claim 3
Dependent Claim
18 words
A toy karate device as claimed in claim 1 wherein the pair of mating pieces are molded plastic.
Claim 4
Dependent Claim
31 words
A toy karate device as claimed in claim 1 wherein the horizontal member has a decorative design on the surface to conceal a line of separation between the two mating pieces.
Claim 5
Dependent Claim
17 words
A simulated karate device as claimed in claim 1 wherein the retaining means is a magnetic device.
Claim 6
Dependent Claim
17 words
A simulated karate device as claimed in claim 1 wherein the retaining means is an adhesive layer.
Claim 7
Dependent Claim
46 words
A simulated karate device as claimed in claim 1 wherein the retaining means is a layer of upstanding fibers on each mating edge with each layer of fibers interfitting with the opposite layer of fibers when the pieces are pushed together in edge to edge relationship.
Claim 8
Dependent Claim
227 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 longitudinally extending outwardly converging projections alternately defining therebetween, inwardly converging depressions, the projections of one piece extending into the depressions of 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, the configuration of both irregular edges creating the visual appearance of the broken edges of an object that has been broken in two when the two pieces are disassembled; and C. retaining means permanently attached along at least one of the irregular edges to hold together the two pieces when placed in edge to edge relationship with each other but permitting separation of the two pieces when the separable element is struck with the hand to create the illusion of breaking a single continuous element, D. said retaining means having an outwardly facing surface which follows the contour of the adjacent portions of the irregular edge of the piece to which it is attached and adjacent portions of the mating irregular edge of the opposite piece.
Claim 9
Dependent Claim
227 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 longitudinally extending outwardly converging projections alternately defining therebetween, inwardly converging depressions, the projections of one piece extending into the depressions of 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, the configuration of both irregular edges creating the visual appearance of the broken edges of an object that has been broken in two when the two pieces are disassembled; and C. retaining means permanently attached along at least one of the irregular edges to hold together the two pieces when placed in edge to edge relationship with each other but permitting separation of the two pieces when the separable element is struck with the hand to create the illusion of breaking a single continuous element, D. said retaining means having an outwardly facing surface which follows the contour of the adjacent portions of the irregular edge of the piece to which it is attached and adjacent portions of the mating irregular edge of the opposite piece.
