  • Patent number: 6851284
    Abstract: The present invention relates to a pair of handcuffs which cannot be disassembled easily by securing a firm connection therebetween by hinge members. The handcuffs according to the present invention are made by the methods of shearing and bent-up forming in replacement of the conventional cast-iron method, and are connected by a connecting structure which comprises two frame plates, each of which includes a plurality of hinge members forming grooves between the neighboring hinge members and having openings therethrough and also includes a pair of flat members; couplings fitted into the grooves of the hinge members; and hinge axes to be axially fitted into the openings of the hinge members and the couplings.
