Abstract

A bicycle lock in the form of a cable lock includes an elongated lock body and a cable having first and second ends. The first end is fixed to one end of the elongated lock body and another end of the lock body has an insertion opening for an insertion pin that is attached to the second end of the cable and provided with two lateral, diametrically opposed recesses that are oriented parallel to a longitudinal direction of the lock body. Two locking bolts are insertable into the recesses in a translatory manner in the longitudinal direction of the lock body for securing the insertion pin in the lock body. The locking bolts form a part of a locking device. A driver, which lies with inner ends in an effective area of the drive, is rotatable by means of a closing cylinder. By actuation of the closing cylinder, the locking device is drivable in the longitudinal direction of the lock body. The locking device has a first section extending in the longitudinal direction of the lock body and a second, bracket section oriented perpendicular to the lock body longitudinal direction on its outer end. The locking bolts, which are preferably cylindrical, are insertable into the first and second sections on opposite sides of the bracket section.

Claims

1. A bicycle lock in the form of a cable lock, comprising:

an elongated lock body;

a cable having first and second ends, wherein the first end is fixed to one end of the elongated lock body and wherein another end of the lock body has an insertion opening for an insertion pin that is attached to the second end of the cable and that is provided with two lateral, diametrically opposed recesses that are oriented parallel to a longitudinal direction of the lock body; and

one locking device, which is moveable in a translatory movement in a longitudinal direction of the lock body, wherein the locking device is in the form of a unitary member consisting of a first, elongate section extending in the longitudinal direction of the lock body and a second, bracket section disposed at an end of said first elongate section and extending perpendicularly relative to the longitudinal direction of the lock body and to the first section over an angle in a range of 180°

or more and having diametrically opposed recesses on diametrically opposed ends, wherein each of said diametrically opposed ends supports two substantially cylindrical locking bolts for engagement in the two diametrically opposed recesses of the insertion pin for securing the insertion pin within the lock body, wherein said locking device and the two substantially cylindrical locking bolts supported by said locking device are moveable together as a unit, wherein the inner end of the locking device is disposed to lie directly within an effective range of a driver that is rotatable by means of a closing cylinder, wherein by means of actuation of the closing cylinder, the locking device is drivable in the longitudinal direction of the locking body, and wherein driver elements mounted on the locking bolts engage in said recesses of said bracket section.

2. The bicycle lock of claim 1, wherein the driver supports a driver pin eccentrically to its axis of rotation, wherein the driver pin engages in a guide track mounted in the area of the inner end of the locking device, and wherein the guide track extends substantially perpendicular to the movement direction of the locking device.

3. The bicycle lock of claim 2, wherein each guide track is formed as a slotted hole.

4. The bicycle lock of claim 2, wherein the driver is pre-stressed by means of a spiral spring in the direction of the locking position of the locking device.
