Bicycle brake pad replacement aids

Abstract

A bicycle brake pad changing aid includes: a main body having a base, a mounting seat, and a backing seat; the mounting seat and the backing seat are respectively connected to opposite sides of the base, and a movable space is formed above the base; a pushing assembly having a pivot and a pushing block; the pivot rotatably passes through the main body; the pushing block is disposed in the movable space of the main body and screwed onto the pivot, and is driven by the pivot to move in the movable space toward or away from the backing seat; and a movable member movably disposed in the movable space of the main body and abuts against the pushing block and the backing seat of the pushing assembly, and is pushed by the pushing block to move toward or away from the base, thereby adjusting a distance between the movable member and the base.

Claims

1. A brake pad changing aid for a bicycle, comprising: a main body having a base, a mounting seat, and a backing seat; the mounting seat and the backing seat are respectively connected to opposite sides of the base, and a movable space is formed above the base; a pushing assembly having a pivot and a pushing block; the pivot rotatably passes through the main body; the pushing block is disposed in the movable space of the main body and screwed onto the pivot, and is driven by the pivot to move in the movable space toward or away from the backing seat; and a movable member movably disposed in the movable space of the main body and abuts against the pushing block and the backing seat of the pushing assembly, and is pushed by the pushing block to move toward or away from the base, thereby adjusting a distance between the movable member and the base.

2. The bicycle brake pad replacement aid as described in claim 1, wherein the push block is driven by the pivot to move between a first position and a second position; when the push block moves to the first position, the push block is against one side of the mounting seat; when the push block moves to the second position, the push block moves away from the mounting seat and is spaced a certain distance from the abutment seat.

3. The bicycle brake pad replacement aid as described in claim 2, wherein the distance between the movable element and the base gradually increases as the push block is driven to move from the first position to the second position.

4. The bicycle brake pad replacement aid as described in claim 2, wherein the mounting base has a first through hole; the abutment has a second through hole corresponding to the first through hole; the base has a track with its two ends connected to the first through hole and the second through hole respectively; wherein the pivot passes through the through hole, the track and the second through hole.

5. The bicycle brake pad replacement aid as described in claim 4, wherein the end of the track adjacent to the second perforation has a stop surface; when the push block moves to the second position, the push block abuts against the stop surface.

6. The bicycle brake pad replacement aid as described in claim 4, wherein the mounting base has a limiting space communicating with the first through hole; the push assembly further includes a buckle and a sleeve located in the limiting space and fitted onto the pivot to prevent the pivot from detaching from the body.

7. The bicycle brake pad replacement aid as described in claim 2, wherein the abutment has at least one first inclined surface; the push block has at least one second inclined surface; the movable member has a first push surface abutting against the first inclined surface and a second push surface abutting against the second inclined surface on opposite sides, and the inclination angles of the first push surface and the second push surface correspond to the first inclined surface and the second inclined surface, respectively.

8. The bicycle brake pad replacement aid as described in claim 7, wherein the abutment has a first flange on the side facing the push block; the push block has a second flange on the side facing the abutment; the movable member has two first push portions on the side adjacent to the abutment, and a first groove is formed between the two first push portions for engaging with the first flange; the movable member has two second push portions on the side adjacent to the push block, and a second groove is formed between the two second push portions for engaging with the second flange.

9. The bicycle brake pad replacement aid as claimed in claim 8, wherein the movable part forms a groove between the first push portion and the second push portion on the same side; the base further has at least one extension corresponding to the groove; when the push block is in the first position, the extension extends into the groove, and when the push block is in the second position, the extension disengages from the groove.

10. A brake pad replacement aid for a bicycle as claimed in claim 1, wherein the pivot has a threaded portion in at least a portion of the moving space; the push block has a threaded hole that engages with the threaded portion of the pivot.

11. The bicycle brake pad replacement aid as described in claim 1, wherein the push assembly further includes a wheel located on the side of the mounting base away from the abutment and connected to the axle.

12. The bicycle brake pad replacement aid as described in claim 11, wherein the wheel has a non-circular operating hole at its center.

13. The bicycle brake pad replacement aid as described in claim 1 further includes two stops, respectively fixed to the base and the movable part on the side away from each other.

14. The bicycle brake pad replacement aid as described in claim 13, wherein the base and the movable part are each provided with at least one magnet; each of the stops is a metal sheet that is detachably attached to the base and the movable part by the magnetic force of the magnets.

15. The bicycle brake pad replacement aid as described in claim 13, wherein the stop member has a slot on each of its two opposite sides; the base and the movable member are respectively provided with two engaging protrusions on their opposite sides, corresponding to the two slots, such that when the stop member is fixed to the base or the movable member, the two engaging protrusions engage with the two slots.
