Abstract

A bicycle frame element has a seat tube ( 10 ). A clamping element ( 20 ) is arranged in the seat tube ( 10 ), on which element a clamping force is exerted by a clamping means ( 34 ) to fix a seat post ( 30 ) in the seat tube ( 10 ). Further, a bearing element ( 22 ) for defining the lateral position of the seat post ( 30 ) is arranged in the end portion ( 16 ) of the seat tube ( 10 ), when in the mounted state.

First claim

1 . A bicycle frame element comprising
a seat tube, a clamping element arranged in the seat tube, on which element a clamping force is exerted by a clamp to fix a seat post in the seat tube, the clamp being arranged in the seat tube, and a bearing element for defining the lateral position of the seat post, the bearing element being arranged in the end portion of the seat tube.

2 . The bicycle frame element of claim 1 , wherein the clamping element comprises a protrusion which, in the mounted state, protrudes into a recess of the seat tube, the clamp preferably acting on the protrusion.

3 . The bicycle frame element of claim 1 , wherein the clamp immediately generates a clamping force acting substantially perpendicular to the seat post.

4 . The bicycle frame element of claim 1 , wherein the clamp is arranged in a frame center plane.

5 . The bicycle frame element of claim 1 , wherein the clamp is arranged between two seat stays that are preferably connected with the seat tube.

6 . The bicycle frame element of claim 1 , wherein the bearing element is formed in a closed shape, in particular an annular shape so as to surround the seat post, when in the mounted state.

7 . The bicycle frame element of claim 1 , wherein the bearing element has a preferably circumferential collar resting on an end face of the seat tube, when in the mounted state.

8 . The bicycle frame element of claim 1 , wherein the inner dimension of the bearing element substantially corresponds to the outer dimension of the seat post.

9 . The bicycle frame element of claim 1 , wherein the clamping element is connected with the bearing element via a connecting web, the components being formed in particular as an integral retaining device.

10 . A retaining device for fixing a seat post in a seat tube of a bicycle frame, in particular a bicycle frame of claim 1 , comprising
a clamping element adapted to be arranged in the seat tube, on which element a clamping force is exerted by a clamp to fix a seat post in the seat tube, the clamp being adapted to be arranged in the seat tube, and a bearing element for defining the lateral position of the seat post, the bearing element being adapted to be arranged in the end portion of the seat tube.

11 . The retaining device of claim 10 , wherein the clamping element has a protrusion which, in the mounted state, protrudes into a recess of the seat tube, the clamp preferably acting on the protrusion.

12 . The retaining device of claim 10 , wherein the bearing element is formed in a closed shape, in particular an annular shape so as to surround the seat post, when in the mounted state.

13 . The retaining device of claim 10 , wherein the bearing element has a preferably circumferential collar resting on an end face of the seat tube, when in the mounted state.

14 . The retaining device of claim 10 , wherein the clamping element is connected with the bearing element via a connecting web, the components being formed in particular as an integral retaining device.

15 . A bicycle frame comprising a seat tube and a top tube connected with the seat tube, the seat tube having an opening directed into the top tube.

16 . The bicycle frame of claim 15 , wherein the opening has an inner cross section of the top tube in the transition region between the seat tube and the top tube.

17 . The bicycle frame of claim 15 , wherein the seat tube is designed to receive a retaining device for fixing a seat post in the seat tube, wherein the retaining device comprises
a clamping element adapted to be arranged in the seat tube, on which element a clamping force is exerted by a clamp to fix a seat post in the seat tube, the clamp being adapted to be arranged in the seat tube, and a bearing element for defining the lateral position of the seat post, the bearing element being adapted to be arranged in the end portion of the seat tube.

18 . The bicycle frame element of claim 1 , wherein the clamp comprises a screw exerting a force on the clamping element.

19 . The retaining device of claim 10 , where the clamp comprises a screw exerting a force on the clamping element.
