  • Patent number: 6889734
    Abstract: A wheel chain has a running lattice structure which is tightened by a pressure cord (8). The pressure cord (8) is connected to a lateral lattice structure arranged on the outer side of the vehicle tires by connecting members (6). Each of the connecting members has a connecting loop (10) for a member of the lateral lattice structure, and a guiding ring (9) for the pressure cord (8). In order to preserve an excess length (7) of the pressure cord (8), the cross-section of the connecting loop (10) is sufficiently large so that the connecting loop (10) provides a pull-through conduit for the excess length (7) of the pressure cord (8).

  • Patent number: 6874206
    Abstract: A component (1) for regulating or modifying the effective length of a round steel chain (22) has at least one cross recess consisting of a longer recess (12) and a shorter recess (6). The chain can be threaded into the cross recess. The component also has a pin (11) for fixing the component in a particular position in relation to the chain (22). The pin forms a blocking element and has at least one groove (14) which forms the end of the longer recess when the cross recess is free. During normal operation, the groove is forced by a spring (10) into a position in which the pin (11) blocks the cross recess.

  • Patent number: 6223517
    Abstract: In the case of a connecting chain link for link chains having two connecting-link parts (1, 2), their ends (4, 5), which are connected to each other via a respective longitudinal web (3), are held together in the closed position by means of a respective stub (6) gripping into a pocket (7). While each stub (6) is provided with an essentially U-shaped retaining web (19) which has clearances (22, 23) in the region of its limbs (20, 21) running parallel to each other, each pocket (7) is provided with a U-shaped retaining groove (25) whose one wall (24) has recesses (26, 27). The size and position of the clearances (22, 23) and of the recesses (26, 27) make it possible for the connecting-link parts (1, 2) to be joined together in a position in which their stubs (6) and pockets (7) partially overlap.

  • Patent number: 6216434
    Abstract: In a chain lock with essentially U-shaped lock parts (1, 2), each lock part has an inner limb (4) and an outer limb (3) which are connected to each other by a yoke. The outer and inner limbs (3, 4) are connected to each other in a closed position of the lock by three pairs of holding teeth (5, 8; 6, 9; 7, 10). For increasing the strength of the lock, the holding teeth (6, 9) of the central pairs of holding teeth, and the holding teeth (5, 8) of the pairs of holding teeth arranged in the region of the ends of the inner limbs (4), have a greater height (H) than the holding teeth (7, 10) of the other pairs of holding teeth. All holding teeth (5-10) support each other only over a central supporting zone which is limited in its height.
