Abstract
First and second hollow metal members are innerconnected by a rope for use by police, military, and students of martial arts. The rope may be of wire or nylon and is freely slideable with respect to one of the metal members while being freely rotatable with respect to said one member.
Claims10
A hand weapon comprising first and second hollow members of metal, said metal members having transverse perforations, a discrete threaded adapter threaded in one end of each of said members, the transverse dimensions of said adapters being not greater than the transverse dimensions of their associated metal member, each adapter having a central bore, a flexible member extending through said bores and interconnecting said metal members, means associated with the free ends of said flexible member for preventing the flexible member from being withdrawn through the bore of its associated adapter, means associated with one end portion of said flexible member and its hollow metal member for adjusting the length of the flexible member exposed between said adapters, the exposed end portion of said adapters being conical or semispherical, and said metal members having a plurality of flat faces thereon.
A device comprising first and second hollow members of rigid metal, each of said metal members having a bore at one end thereof, a rope extending through said bores and interconnecting said members, each end of said rope terminating within one of said metal members, at least one end portion of said rope being freely slideable with respect to its metal members so that the distance between the bore ends of said metal members may be decreased, means associated with ends of said rope to limit the extent of the distance between said bore ends of said metal members, and said metal members being provided with staggered sets of holes therethrough in a direction generally perpendicular to the longitudinal axes of said metal members.
A device comprising first and second hollow members of rigid metal, each of said metal members having a bore at one end thereof, a rope extending through said bores and interconnecting said members, each end of said rope terminating within one of said metal members, at least one end portion of said rope being freely slideable with respect to its metal members so that the distance between the bore ends of said metal members may be decreased, means associated with ends of said rope to limit the extent of the distance between said bore ends of said metal members, and said metal members being of a lightweight metallic material which is rectangular in cross section with beveled corners.
A device comprising first and second members of hollow aluminum, said members having tarnsverse perforations, said members having a length of approximately 1 foot, a discrete threaded adaptor in one end of each of said members, each adaptor having a central bore, a rope extending through said bores and innerconnecting said metal members, each end of said rope terminating within one of said metal members, one end portion of said rope being freely rotatable and slideable with respect to the first metal member, the other end portion of said rope being adjustably connected to said second metal member, and means associated with each end portion of said rope to limit the maximum extent of the distance between said adaptors to thereby define the extent of the exposed portion of said rope.
