Abstract
Abstract The invention involves a striking board for use in developing one's skill in the martial arts and comprises in its basic aspects in superimposed relation, a relatively flexible cushion member for striking with one's hand, supported by a relatively inflexible member, which in turn is supported by a relatively inflexible spacing member and a further relatively inflexible member, the latter member being of such a construction that the striking board can be held by hand or supported by a bracket support on a wall or other support surface. The bracket support supports the striking board of the invention by compression springs so as to offer suitable resistance to a striking blow. The striking board can be removed from the bracket support, if desired, and hand held by a training partner. The striking board is covered with leather or leather-like plastic coated fabric so as to present a pleasing appearance to the striking board, and less abrasiveness to one's hand in use.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
364 words
A striking board for use in developing one's skill in the martial arts comprising in assembly a relatively inflexible baseboard having planar top and bottom surfaces parallel to one another, a striking surface defined by a first pair of parallel side edges defining a first width of the baseboard, and a second pair of parallel side edges defining a lesser second width of the baseboard, said first pair of parallel said edges being parallel with said second pair of parallel side edges, first and second end portions integral with and extending in opposite directions from said striking surface of said baseboard defined by the said second pair of parallel side edges and defining parallel end edges, a relatively inflexible top board having planar top and bottom surfaces parallel to one another, said top board defined by parallel side edges and having a width coextensive with that of the striking surface of the said baseboard and by parallel end edges defining a lesser length non-coextensive to the length of said baseboard but coextensive with the striking surface, a rectangular shaped spacing member intermediate said top board and baseboard having parallel planar top and bottom surfaces and parallel side edges and end edges defining a lesser width and length than said top board, a relatively flexible cushion member having parallel planar top and bottom surfaces, and being of a width and length so as to be coextensive laterally and longitudinally with said top board and said striking surface, and the bottom planar surface of said cushion member being supported by the top planar surface of said top board, a base cover extending over the bottom surface of the baseboard and being secured by means on the top surface thereof, a top cover extending over the top surface of the said flexible cushion member and being secured by means to the bottom surface of the top board, a seam comprising a material folded in half secured to said bottom surface of the top board around and along its perimeter, and means securing said baseboard, spacing member and top board in assembly together, said seam in the assembly being located around the perimeter of the rectangular spacing member.
Claim 2
Dependent Claim
