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.
Claims18
A bicycle frame element comprising:
- a seat tube,
- a clamping element arranged in the seat tube, on which element a clamping force substantially perpendicular to a seat post is exerted by a clamp to fix the 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 an end portion of the seat tube,
- wherein the clamping element comprises a protrusion which, in a mounted state, protrudes into a recess of the seat tube in a direction of the clamping force, the clamp acting on the protrusion,
- wherein the recess defines an indentation or a hole extending in the direction of the clamping force in order to define a position of the clamping element, and
- wherein vertical and horizontal movement of the clamping element is restricted by the recess in the position of the clamping element defined by the indentation or the hole.
A retaining device for fixing a seat post in a seat tube of a bicycle frame, the retaining device comprising:
- a clamping element adapted to be arranged in the seat tube, on which element a clamping force substantially perpendicular to a seat post is exerted by a clamp to fix the 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 an end portion of the seat tube,
- wherein the clamping element comprises a protrusion which, in a mounted state, protrudes into a recess of the seat tube in a direction of the clamping force, the clamp acting on the protrusion,
- wherein the recess defines an indentation or a hole extending in the direction of the clamping force in order to define a position of the clamping element, and
- wherein vertical and horizontal movement of the clamping element is restricted by the recess in the position of the clamping element defined by the indentation or the hole.
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,
- 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 substantially perpendicular to a seat post is exerted by a clamp to fix the 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 an end portion of the seat tube,
- wherein the clamping element comprises a protrusion which, in a mounted state, protrudes into a recess of the seat tube in a direction of the clamping force, the clamp acting on the protrusion,
- wherein the recess defines an indentation or a hole extending in the direction of the clamping force in order to define a position of the clamping element, and
- wherein vertical and horizontal movement of the clamping element is restricted by the recess in the position of the clamping element defined by the indentation or the hole.
