摘要： The present invention concerns a component (10; 110; 210) for a jewellery and/or costume jewellery item (1; 101; 201; 301), suited to be used for making chains, small chains, necklaces, bracelets, earrings and similar items. The component (10; 110; 210) comprises a first element (20; 120; 220) and a second element (40; 140; 240) connected together in such a way as to form a chain section. The first element (20; 120; 220) and the second element (40; 140; 240) can be coupled at the level of two contact areas (62, 64; 162, 164; 262, 264), wherein in at least one of the two contact areas (62, 64; 162, 164; 262, 264) the first element (20; 120; 220) comprises a first contact surface (22, 24; 122, 124; 222, 224) which is lowered with respect to the adjacent surfaces (22a, 22b; 24a, 24b) and wherein the first lowered contact surface (22, 24; 122, 124; 222, 224) is suited to receive a second contact surface (42, 44; 142, 144; 242, 244) of the second element (40; 140; 240). The component (10; 110; 210) comprises articulation means (12; 112; 212) for coupling the component (10; 110; 210) with another component (10; 110; 210) of the jewellery and/or costume jewellery item (1; 101; 201; 301).

摘要： A chain having a horizontal chain link and a vertical chain link linked in the horizontal chain link. The chain links each having two legs and two opposite bows connecting the legs to one another, such that the links each form self-contained courses. The horizontal link has a functional section on at least one bow designed, on the one hand, in a blocking plane such that the functional section cannot plunge through the vertical link arranged in a first orientation relative to the horizontal link, and, on the other hand, with a width that is narrower than the inner width of the vertical link such that that functional section can plunge through the vertical link arranged in a second orientation relative to the horizontal link. The horizontal link has an inner support section in the inward-facing apex bow region and, on the functional section, provides an outer support path leading around the course of the horizontal link for supporting the vertical link.

摘要： The design of chain links for energy chains for movably carrying cables, hoses and the like. The chain link consists of a plurality of individual parts, namely two side plates made of plastic, comprising an interior side facing the interior of the chain link, an exterior side facing away therefrom and two narrow sides running substantially parallel to the longitudinal direction, and at least one, more particularly two transverse connecting pieces for detachably connecting the side plates, comprising a center part and a fastening portion at each end of the transverse connecting piece on both sides. The side plates have, on at least one narrow side, a corresponding fastening region for frictionally fastening a transverse connecting piece, namely a clamping receptacle which has two clamping surfaces, which are opposite one another in the longitudinal direction and between which a complementarily shaped fastening portion of the at least one separate transverse connecting piece is clamped. Each transverse connecting piece has two support protrusions on each fastening portion, each support protrusion having a support surface for resting against the interior side of the side plate in order to achieve a robust connection. Providing the side plate, in the central region between the fastening regions, with a special functional cut-out in the plate body, which cut-out facilitates additional functions or application expansions.

摘要： A chain unit lubricated and sealed with magnetic fluid includes a pin shaft, a magnetic sleeve, a first pole piece and a second pole piece. The sleeve is fitted over an outer periphery of the pin shaft. Both ends of the pin shaft protrude from the sleeve. A first gap exists between an inner peripheral surface of the sleeve and an outer peripheral surface of the pin shaft. The first pole piece is arranged at one of the sleeve and has a first mating hole. A second gap exists between an inner wall surface of the first mating hole and the outer peripheral surface of the pin shaft. The second pole piece is arranged at the other end of the sleeve and has a second mating hole. A third gap exists between an inner wall surface of the second mating hole and the outer peripheral surface of the pin shaft.
