发明名称 Link chain
摘要 An elongated link chain includes a plurality of hingedly connected chain links. Each chain link is made of punched out sheet metal defining a first plane, and includes two lateral walls extending in the longitudinal direction of the chain and spaced from one another in a direction transverse to the longitudinal direction. At least one transverse web in the first plane rigidly interconnects the lateral walls for holding the walls in position with respect to one another. Each lateral wall includes an arm, and each arm has an end portion constituting a bearing pin. Each lateral wall has a separate bearing hole punched-out in the sheet metal for receiving the respective associated bearing pin of another identical chain link which is arranged adjacently to the bearing holes; the separate bearing holes are made coaxial with one another by bending the lateral walls in a direction approximately at right angles to the first plane, so as to extend in a second plane, and to constitute an approximately U-shaped bracket with the transverse web, in which the bearing holes are spaced at an axial distance from one another. The bearing holes define a first axis, and the parts of respective end portions of the bearing pins define a second axis, which axes are parallel to one another. The bearing pins are bent back so that at least parts of respective end portions extend in a direction approximately parallel to that of the transverse web.
