  • Patent number: 5411190
    Abstract: A luggage carrier which can be adapted to different sizes of bicycle frames and shapes is provided. A supporting frame of the luggage carrier is supported in the region of the rear wheel bearing by supporting frame supports. The front end region of the supporting frame is connected by means of a swivelling part to a pair of bars of the bicycle frame extending from the region of the rear wheel bearing to the upper end region of a saddle tube. The position of the swivelling part is adjustable along the length of the supporting frame, and the swivelling part is secured at a desired position for operation. The swivelling part is swivellable around an axis orthogonal to the longitudinal central plane of the luggage carrier.

  • Patent number: 5189893
    Abstract: A shackle lock, particularly with a long shackle, comprises a lock body and a lock shackle with two shackle arms, the free end portions of which are displaceable into a shackle arm housing of the lock body until they reach a locking position of the lock shackle. A lock mechanism is rotatable about an axis of rotation, particularly by a key. Disposed in the lock body is at least one locking element which meshes with the closure mechanism and which, upon actuation of the closure mechanism, is guided for movement out of a lock shackle arresting position in which the locking element is in engagement with the end portion of at least one shackle arm for locking the lock shackle and for movement into a lock shackle releasing position in which the locking element is out of arresting engagement with the end portion of the shackle arm. In this lock shackle releasing position the shackle arm can be withdrawn completely from the shackle arm housing.

  • Patent number: 5170650
    Abstract: In the case of a locking device for a lock, especially a ring lock, comprising a connecting part (14) and a connecting part case (16) with a snap-in locking device (22, 24, 30), operated with a locking mechanism (32) a ratchet body (22) is accomodated in a guide passage (26) of a ratchet body guide element (24) oriented transversely to the direction of insertion of the connecting part (14) and is opposite a guide surface (30 at 31) at its side remote from the inserted connecting part (14). The guide surface (30), when the ratchet body guide element (24) is in a locking position, urges the ratchet body (22) behind a ratchet shoulder (20) of the connecting part (14) into an engagement position which prevents withdrawal of the connecting part (14).

  • Patent number: 4944168
    Abstract: The cable lock has a flexible cable portion and an elongated lock body at one end of the cable portion which is enclosed by a two-part synthetic plastics casing. The plastics casing comprises a cap-shaped outercasing part which substantially completely encloses an inner casing part which fixes the lock body in its longitudinal direction. The inner casing part carries a tubular projection which together with the cable portion passes through an aperture in an end wall of the outer casing part. The inner edge of the aperture is fitted by snap-action in an annular groove in the tubular projection. The synthetic plastics casing of the cable lock is mechanically rugged and its snap-action joint is visually unobtrusive.

  • Patent number: 4881387
    Abstract: In the case of a long shackle lock, the end portions of the lock shackle are inserted into housings in a lock body. When this happens, they act on lock control sleeves pushing them out of a lock influencing position into a lock releasing position. The lock bolts move into the engaged position, i.e. in engagement with engagement surfaces on the end portions. The lock cylinder which controls the lock bolts moves into its basic position. The key can be withdrawn. To undo the lock, the lock cylinder is turned into a lock opening condition by the key which will then have been re-inserted. When this happens, the lock bolts are retracted into a disengaged position. The control sleeves then push the end portions at least partially out of the housings. The control sleeves move into the bolt influencing position. Therefore, the lock bolts remain in the disengaged position until the end portions are again inserted into the housings (FIG. 1).

  • Patent number: 4831849
    Abstract: The cable lock comprises a flexible cable portion and an elongate lock body to which the cable portion is secured, oriented in the longitudinal direction of the lock body, by a first end and can be attached, oriented transversely to the longitudinal direction of the lock body, by a second end. A plastics housing, furnished with through openings for the ends of the cable portion, encases the lock body. The housing consists of two housing parts, pushed into each other in the longitudinal direction of the lock body and engaged with each other when pushed in, which housing parts are fixed by abutment surfaces against opposed abutment surfaces of the lock body. The one housing part forms a pocket, disposed laterally of the lock body, into which pocket a projection of the other housing part can be pushed.

  • Patent number: 4459833
    Abstract: At a swiveling stirrup lock, particularly for a two-wheel vehicle with a swiveling stirrup that can be swiveled through the spokes, the swiveling stirrup is supported in a swivel hub to be rotatable about its longitudinal axis. The swivel hub is supported to be swingable about a swivel axis on a pivot bearing which is to be attached at the bicycle frame. At least in the driving position, the swiveling stirrup is secured by engagement of a rotation securing element, installed at the swiveling stirrup, into a rotation securing element mounting of the pivot bearing. This engagement can be produced or released by rotating the swiveling stirrup into or out of a rotation securing position. The rotation securing element is installed according to the invention at the swiveling stirrup in the region of its outlet from the swivel hub outside the latter.
