  • Patent number: 8038559
    Abstract: The end faces of a first pin contain bulging curved faces having an egg-like shape, when viewed along a chain width direction. Each bulging curved face includes a first end portion, a second end portion and a maximum width portion with respect to a chain advancing direction. With respect to perpendicular directions, the distance between the center of the maximum width portion and the first end portion is relatively large, whereas the distance between the center of the maximum width portion and the second end portion is relatively short. It is possible to enlarge the surface area of the bulging curved face.

The overlay has an overlay front side with adornment, coloration, art work, or embossment, and also an overlay rear side which is intended to be attached to a chain link. The overlay rear side includes a pin head bore corresponding to each pin head extending from the chain link. When the overlay is attached to the chain link, each pin head extending from the chain link is disposed within a pin head bore. The overlay may be attached to the chain link with adhesive, solder, welding, or any other appropriate means of attachment. The overlay front side may feature artwork, coloration, decoration, and/or embossments, to increase the aesthetic appeal of a chain link to which the chain link overlay has been attached.

  • Patent number: 7082722
    Abstract: An elongate spindle member having rigidity and stability against pressure and tensile loads as well as bending and torsional loads is made by winding-up a plurality of mutually interlocking chain links (1, 12), during axial advancement of the chain links, into a helical winding (5, 16) by a winding guide (14). The elongate spindle member, formed by the helical winding, extends between two objects, one of which is connected with the winding guide (14). The first turn of the helical winding is connected with a coupling member for connection with the other of the two objects. The helical winding is formed by drivingly connecting the chain links to a rotatable driving device in the winding guide and retaining each chain link in engagement with neighboring links in the same turn as well as adjacent chain links in neighboring turns.
