Anti-theft device for bicycles

Abstract

An anti-theft device for a bicycle includes a fork unit that has a first fork bar and a second fork bar. The first fork bar has a passage and the second fork bar has a receiving opening. A securing element can be arranged in the fork unit to pass through the first fork bar in the passage and engage in the receiving opening. The securing element passes through a spoke region of a front wheel of the bicycle. The securing element has an engagement contour that engages in the receiving opening. A locking unit with an electromechanical drive is arranged in the second fork bar. The locking unit has a locking contour, which is connected the electromechanical drive and engages in the engagement contour in the locking state. An electronic control unit controls the electromechanical drive to unlock the unit.

Description

Technical field [0001] The invention relates to an anti-theft device for bicycles, especially for bicycle rental systems. Background technique [0002] In order to protect the bicycle against theft, the most different solutions are known from the prior art. [0003] Chain locks, cable locks or bow locks are often used here, by means of which the bicycle is connected to a fixed object and is therefore protected. [0004] On the one hand, the disadvantage of this bicycle lock is that the bicycle lock is always completely accessible from the outside and therefore, depending on the material used, may be destroyed by a thief with little effort and render the bicycle lock inoperative. [0005] In addition, another disadvantage of this bicycle lock is that the bicycle lock must be placed on the bicycle itself during non-use or must be carried by the bicycle user alone, such as in a bag or a backpack. In any case, there is a corresponding additional expense in storing and carrying such bicyc...

AI Technical Summary

Problems solved by technology

[0004] A disadvantage of such a bicycle lock is, on the one hand, that the bicycle lock is always completely accessible from the outside and thus, depending on the material used, can be destroyed by a thief with little effort and render the bicycle lock inoperative.

[0005] Furthermore, another disadvantage of such bicycle locks is that the bicycle lock must be mounted on the bicycle itself when not in use or must be carried by the bicycle user separately, for example in a bag or in a backpack

[0009] Especially in the area of ​​public rental systems when the bicycle is in operation, the components of the bicycle lock are often subjected to constant weather effects, which can cause corresponding functional impairments, especially of the components responsible for locking the locking bolt.
