Abstract

An adjusting structure for a seatpost of a bicycle includes a telescopic post and at least one adjusting module. The telescopic post includes at least one switch disposed on one end of the telescopic post, wherein the switch is for lengthening or shortening the telescopic post. The adjusting module is disposed on the telescopic post corresponding to the switch and for pushing the switch.

First claim

What is claimed is:

1. An adjusting structure for a seatpost of a bicycle, comprising:
a telescopic post comprising at least one switch disposed on one end of the telescopic post, wherein the switch is for lengthening or shortening the telescopic post; and
at least one adjusting module disposed on the telescopic post corresponding to the switch and for pushing the switch, wherein the adjusting module is a first adjusting module, and the first adjusting module comprises:
a first pushed lever, one end of the first pushed lever corresponds to the switch; and
a first linking lever corresponding to the first pushed lever, wherein one end of the first linking lever is driven to swing the other end of the first linking lever, and the other end of the first linking lever is directly linked up with the other end of the first pushed lever, a driven direction of the first linking lever is opposite to a pushing direction of the first pushed lever.

2. The adjusting structure of claim 1 , wherein the other end of the first pushed lever pushes the switch.

3. The adjusting structure of claim 1 , wherein the first pushed lever is pivotally connected to the telescopic post.

4. The adjusting structure of claim 1 , further comprising:
a wire rope, one end of the wire rope detachably connected to the adjusting module; and
a controlling module detachably connected to the other end of the wire rope and for linking up with the wire rope to control the adjusting module.

5. The adjusting structure of claim 4 , wherein the controlling module is a lever or a connecting rod.

6. The adjusting structure of claim 1 , wherein the switch in the telescopic post comprises two switches disposed on two ends of the telescopic post, respectively.

7. The adjusting structure of claim 6 , wherein the adjusting structure comprises two adjusting modules correspond to two switches, respectively.

8. The adjusting structure of claim 7 , wherein the other one of the adjusting modules is a second adjusting module, the second adjusting module comprises:
a second pushed lever, one end of the second pushed lever corresponds to the other switch; and
a second linking lever, corresponding to the second pushed lever and pivotally connected to the telescopic post, wherein one end of the second linking lever is driven to swing the other end of the second linking lever, and the other end of the second linking lever is linked up with the other end of the second pushed lever, thus the other end of the second pushed lever pushes the switch.

9. The adjusting structure of claim 7 , wherein the other one of the adjusting modules is a second adjusting module, the second adjusting module is a lever, a connecting rod, a cam wheel, a roller or a motor.

10. The adjusting structure of claim 7 , further comprising:
a wire rope, one end of the wire rope detachably connected to any one of the adjusting modules; and
a controlling module detachably connected to the other end of the wire rope and for linking up with the wire rope to control the adjusting module connected to the wire rope.

11. The adjusting structure of claim 8 , wherein the second pushed lever is pivotally connected to the telescopic post.

12. An adjusting structure for a seatpost of a bicycle, comprising:
a telescopic post;
a length adjusting module contained in the telescopic post, two ends of the length adjusting module pushing against two ends of the telescopic post respectively, wherein the length adjusting module comprises at least one switch located on one of the ends of the length adjusting module, the switch is exchangeably disposed on any one of two ends of the telescopic post;
a first adjusting module disposed on one end of the telescopic post and for pushing the switch; and
a second adjusting module disposed on the other end of the telescopic post and for pushing the switch.

13. The adjusting structure of claim 12 , wherein the telescopic post comprises two assembling bases, and the length adjusting module comprises two assembling units, wherein the assembling units are exchangeably connected to the assembling bases of the telescopic post, respectively.

14. The adjusting structure of claim 13 , wherein one of each assembling base and each assembling unit is concave-shaped, and the other one of each assembling base and each assembling unit is convex-shaped.

15. The adjusting structure of claim 13 , wherein each of the assembling bases comprises:
two assembling holes; and
two assembling pins located through the assembling holes respectively and fastened to the assembling units of the length adjusting module respectively.

16. The adjusting structure of claim 13 , wherein each of the assembling bases comprises:
an assembling clip disposed on the assembling base for fastening the assembling units.

17. The adjusting structure of claim 13 , wherein one of each assembling base and each assembling unit is screw thread, and the other one of each assembling base and each assembling unit is screw thread.

18. The adjusting structure of claim 12 , wherein the first adjusting module is a lever, a connecting rod, a cam wheel, a roller or a motor.

19. The adjusting structure of claim 12 , wherein the first adjusting module comprises:
a first pushed lever, when the switch corresponds to the first adjusting module, one end of the first pushed lever corresponds to the switch; and
a first linking lever corresponding to the first pushed lever and pivotally connected to the telescopic post, wherein one end of the first linking lever is driven to swing the other end of the first linking lever, and the other end of the first linking lever is linked up with the other end of the first pushed lever, thus the other end of the first pushed lever pushes the switch.

20. The adjusting structure of claim 19 , wherein the first pushed lever is pivotally connected to the telescopic post.

21. The adjusting structure of claim 19 , wherein the second adjusting module comprises:
a second pushed lever, when the switch corresponds to the second adjusting module, one end of the second pushed lever corresponds to the switch; and
a second linking lever corresponding to the second pushed lever and pivotally connected to the telescopic post, wherein one end of the second linking lever is driven to swing the other end of the second linking lever, and the other end of the second linking lever is linked up with the other end of the second pushed lever, thus the other end of the second pushed lever pushes the switch.

22. The adjusting structure of claim 12 , further comprising:
a wire rope, one end of the wire rope detachably connected to the first adjusting module or the second adjusting module.

23. The adjusting structure of claim 22 , further comprising:
a controlling module detachably connected to the other end of the wire rope and for linking up with the wire rope to control the first adjusting module or the second adjusting module.

24. The adjusting structure of claim 21 , wherein the second pushed lever is pivotally connected to the telescopic post.

25. The adjusting structure of claim 1 , wherein a center of the first linking lever is pivotally connected to the telescopic post.
