Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In the following, the disclosure is described in more detail by means of a preferred embodiment with reference to the accompanying drawings. In the drawings:

[0023] FIG. 1 shows a schematic perspective view of the two stop elements,

[0024] FIG. 2 shows a schematic perspective top plan view on the cover element, and

[0025] FIG. 3 shows a partly sectional view of the entire steering stop in the mounted state.

DESCRIPTION OF THE DISCLOSURE

[0026] The steering stop comprises a first stop element 10, as well as a second stop element 12 cooperating therewith. The first stop element 10, which in particular is designed to be annular in shape, comprises two mutually opposite stop elements 14, 16. Each stop element 14, 16 has a stop surface 20, 22 on the rear side facing in the direction opposite to the direction of travel 18. When the handlebar is turned left in the traveling direction, the steering angle is limited by the fact that the stop surface 20 abuts against a stop surface 24 of the second stop element 12, which is the left stop surface in the traveling direction. Analogously, the stop surface 22 of the stop 16 abuts against the right stop surface 26 in the case of an extreme right steering angle.

[0027] In the preferred embodiment illustrated, the first stop element 10 is clampingly fixed to a steer tube not illustrated. To this end, the first stop element has a slot 28, the slot width and thus the inner diameter of the first stop element being adapted to be reduced using a clamping element such as a clamping screw 30.

[0028] According to the disclosure, in the embodiment illustrated, the first stop element comprises two recesses 32, 34. These recesses are arranged on the opposite side of the stop surfaces 20, 22 of the stops 14, 16, respectively. In other words, the two recesses 32, 34 are arranged in front of the stops 14, 16 with respect to the traveling direction 18. As such, it is possible to insert lines into the frame in this area, in particular into the head tube of the frame.

[0029] For covering, the first stop element 10 is a cover element 36 (FIG. 2) which is preferably also formed to be annular in shape. The cover element 36 has a nose directed downward and not visible in the Figure, which nose engages in a recess 38 (FIG. 1) of the first stop element, so that a twisting of the cover element 16 is prevented.

[0030] The cover element has passage openings 40, 42 in the area of the recesses 32, 34. Both passage openings are closed by a closure element 44, respectively, each closure element 44 comprising two cross-shaped slots for passing lines, cables, and the like therethrough, so that these can be passed through in a sealed manner.

[0031] In the mounted state, the passage opening 42 is arranged above the recess 32 and the passage opening 44 is arranged above the recess 34.

[0032] Furthermore, the cover element 36 has a passage opening 48 which is also closed by a closure element 50 with slots 46. The passage opening 46 serves for passing a tool therethrough and, in the mounted state, is arranged at the level of the screw 30.

[0033] In operation, the steering force of the first stop element 10 on the steer tube is set such that, when one of the two stops 14, 16 strikes, initially the first stop element twists on the steer tube. The first stop element can be turned back and be clamped again in a simple manner by loosening the screw 30.

[0034] The second stop element comprises a retaining element 50, as well as a stop 52. The stop 52 forms the opposing stop surfaces 24, 26. The stop 52 is connected to the retaining element 50 via a connecting web 54. Here, the connecting web 54 serves as a rated breaking point. If, for example, the first stop element is not twisted on the steer tube because of excessive clamping forces or, for example, because of contamination, the connecting web will break, so as to prevent excessive force from being introduced into the bicycle frame via the retaining element 50.

[0035] In the mounted state (FIG. 3), a head stube 56 of the bicycle frame is connected to or formed integrally with a top tube 58. The steer tube of the bicycle fork is arranged in the head tube 56 and is rotatably supported by an upper headset bearing 60 and a lower headset bearing which is not illustrated. In the embodiment illustrated, a respective compression ring 62 is provided for fixing the headset bearings 60. The same preferably also has line passages, provided that the compression ring 62 is also arranged in the area of the recesses 32, 34. After the pretensioning of the two head-set bearings 60, the first stop element 10 is clampingly fixed, so that the pretension of the headset bearings is maintained, regardless of whether the stem is mounted or dismounted.

[0036] The retaining element 50 of the second stop element 12 is inserted into a recess 64, which is provided on a side of the top tube 58 facing in the direction of the head tube 56. In the embodiment illustrated, fixing is effected by the upper headset bearing 60.

[0037] Since the retaining element 50 is arranged in the recess 54 provided in the top tube 58, the same is not visible.

[0038] Then, the cover element 36 (FIG. 2), which is illustrated only schematically in FIG. 3, is arranged above the first stop element 10.
