Abstract
With the invention is presented an anti-theft device for bicycles, which comprise a bicycle frame (2) and a steering column (14) mounted on the bicycle frame (2) for steering the bicycle, which steering column is provided for a rotationally fixed coupling of bicycle handlebars (6) with a fork (5) for a front wheel (4), having a separating means for nuetralising the rotationally fixed coupling, wherein a coupling piece (8) or a connecting element (60) is provided as separating means, which divides the steering column (14) into two parts (34) and produces the rotationally fixed coupling of these steering column parts (34) in a first state and neutralises it in a second state.
Claims19
An anti-theft device for a vehicle comprising frame and a steering column for steering the vehicle which steering column rotationally fixedly couples a steering mechanism, said device comprising:
- a coupling piece for neutralising the rotationally fixed coupling, which separates the steering column into two parts and produces the rotationally fixed coupling of these steering column parts when in a first state and neutralises it when in a second state, and
- wherein the coupling piece comprises a column piece, which in the first state is inserted between the steering column parts and aligns with them, and which in the second state is completely removed from the steering column parts.
An anti-theft device for a vehicle comprising a steering column for steering the vehicle, which steering column rotationally fixedly couples a steering mechanism, said device comprising:
- a connecting element for neutralising the rotationally fixed coupling, which separates the steering column into two puts and produces the rotationally fixed coupling of these steering column parts when in a first state and neutralises it when in a second state and
- wherein the connecting element has an angular or frame-shaped construction with engagement bars, which are provided for the engagement with claws of the steering column parts in the first state and which move from the first state into the second state by a rotational movement of the connecting element around a center axis thereof at preferably right angles to an axis of the steering column.
