Bicycle Frame Element

Abstract

A bicycle frame element includes a frame tube, such as a downtube. The same forms an accommodation space for accommodating a battery. Further, a channel element is arranged in particular in the frame tube, which extends in the longitudinal direction of the frame tube, and serves to accommodate cables, wires, hydraulic lines and the like. To simplify the mounting, the channel element can be closed with a cover element. The cover element is held so as to be slidable in particular in the longitudinal direction.

Claims

1. A bicycle frame element comprising an accommodation space for a battery, provided in a frame tube, in particular a downtube of a bicycle frame, and a channel element for cables, wires, hydraulic lines, etc. that extends in the longitudinal direction of the accommodation space, wherein a cover element for closing the channel element is provided.

2. The bicycle frame element according to claim 1, wherein the channel element is arranged in the frame tube and extends in particular in the longitudinal direction of the frame tube.

3. The bicycle frame element according to claim 1, wherein a holding element for the cover element is provided, extending in the longitudinal direction of the channel element.

4. The bicycle frame element according to claim 3, wherein the holding element is provided at the cover element and/or at the channel element.

5. The bicycle frame element according to claim 3, wherein the holding element is formed as a groove arranged at the channel element, into which groove the cover element can be inserted in the longitudinal direction.

6. The bicycle frame element according to claim 3, wherein the holding element is formed as a groove arranged at the cover element, said groove cooperating with a protrusion of the channel element extending in the longitudinal direction.

7. The bicycle frame element according to claim 6, wherein the channel element comprises at least two chambers extending in the longitudinal direction.

8. The bicycle frame element according to claim 7, wherein the chambers are separated by a web which extends in particular in the longitudinal direction.

9. The bicycle frame element according to claim 8, wherein the web forms a part of the holding element, the web preferably having two holding elements.

10. The bicycle frame element according to claim 1, wherein the channel element has a rear wall extending in the longitudinal direction, the outer side thereof preferably having a contour that substantially corresponds to the contour of an inner side of the frame tube.

11. The bicycle frame element according to claim 10, wherein the web is arranged on an inner side of the rear wall of the channel element and is preferably formed integrally with the rear wall.

12. The bicycle frame element according to claim 10, wherein the web has at least one threaded bore which, in the mounted state, aligns with passage bores in the frame tube.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In the following, the disclosure is described in more detail by means of a preferred embodiment with reference to the accompanying drawings.

[0018] In the drawings:

[0019] FIG. 1 is a schematic sectional view of a channel element with a cover element,

[0020] FIG. 2 is a schematic perspective view of the channel element with a cover element illustrated in FIG. 1 and

[0021] FIG. 3 is a schematic sectional view of a frame tube with a channel element with a cover element and a battery arranged therein.

DETAILED DESCRIPTION

[0022] The channel element 10 manufactured in particular as an extruded profile has a rear wall 12 passing into two side walls 14 extending parallel to each other. On an inner side 16 of the rear wall 12, a web 18 is formed which also extends completely in the longitudinal direction 20.

[0023] In the embodiment illustrated, two chambers 22 are formed. The two chambers 22 can each be closed with a cover element 24, the cover element 24 being slidable in the longitudinal direction 20.

[0024] Holding elements 26 are provided to hold the cover elements 24. Each of these comprises a groove 28 extending in the longitudinal direction 20. One respective cover element can be inserted into or withdrawn from the grooves 28 in the longitudinal direction 20.

[0025] In the mounted state (FIG. 3), the channel element 10 is arranged inside a frame tube, such as a downtube 30. For this purpose, the contour of an outer side 32 (FIG. 1) of the channel element 10 is formed substantially such that is correspond to the contour of an inner side 34 of the frame tube. The outer side 32 of the channel element 10 thus is in contact with the inner side 34 of the frame profile 30, as can be seen in FIG. 3. Here, the side walls 14 of the channel element 10 may possibly have a shorter distance from the inner side 34 of the frame tube 30.

[0026] In the web 18, threaded bores (not illustrated) can be provided which extend perpendicular to the inner side 34 of the frame tube 30. Passage bores in the frame tube 30, which are not illustrated either, are aligned with these. The latter serve in particular to fix a bottle holder to an outer side 36 of the frame tube by means of bolts.

[0027] Further, the frame tube 30 forms an accommodation space 38 that extends in the longitudinal direction, i.e. perpendicular to the drawing plane of FIG. 3. A battery 40 is arranged inside the accommodation space, the position of the battery 40 and the accommodation space 38 is possibly defined by spacers 42.

[0028] In particular before inserting the battery 40 into the accommodation space 38, the cover elements 24 can be withdrawn in a simple manner. Lines, cables, wires etc. can easily be mounted in the then open channels 22. After the mounting or the repair is completed, the channels 22 can be closed again in a simple manner by inserting the cover elements 24. Thereby, the wire lines, cables etc. arranged in the channels 22 are protected from damage when the battery 40 is inserted or withdrawn.
