Integrated handlebar adjustment structure with dual-axis adjustment

Abstract

This invention relates to an integrated handlebar adjustment structure with dual-axis adjustment, comprising a fork suspension, a handlebar, and a neck tube section. The handlebar and the neck tube section are integrally formed and are pivotally connected to the fork suspension via a first pivot locking group and a second pivot locking group located on a first adjustment axis and a second adjustment axis. This allows the handlebar to be adjusted relative to the fork suspension in both height and angle in a dual-axis manner. This avoids the problems of free rotation and axial slippage that occur during adjustment of traditional clamp-type handlebars, and combines the convenience of adjustment with the reliability of use.

Claims

1. An integrated handlebar adjustment structure with dual-axis adjustment, disposed on a front fork steerer tube for supporting a handlebar, comprising: a front fork anchor, sleeved on the top end of the front fork steerer tube, the front fork anchor having a first locking block, the first locking block having a first toothed hole, wherein the axial extension direction of the first toothed hole is defined as a first adjustment axis; a handlebar integrally formed with a neck section, the neck section having a second locking block corresponding to the front fork anchor, the second locking block having a second toothed hole, wherein the axial extension direction of the second toothed hole is defined as a second adjustment axis, and the second adjustment axis is parallel to the first adjustment axis at intervals; A pair of neck tube side covers are respectively disposed on opposite sides of the first pivot block and the second pivot block, and the neck tube side covers are respectively provided with a first transverse shaft hole and a second transverse shaft hole. The neck tube side covers are respectively provided with a first inner locking tooth surface and a second inner locking tooth surface on the outward periphery of the first transverse shaft hole and the second transverse shaft hole. A first pivot locking assembly is disposed between the first toothed hole and the first lateral shaft hole, and is inserted along the first adjustment axis and lockable. The first pivot locking assembly has a first toothed segment and a first locking tooth surface corresponding to the first toothed hole and the first inner locking tooth surface, respectively forming an engagement relationship, for adjusting the height of the handlebar relative to the fork suspension. A second pivot locking assembly is disposed between the second toothed hole and the second lateral shaft hole, and is inserted along the second adjustment axis and lockable. The second pivot locking assembly has a second toothed segment and a second locking tooth surface corresponding to the second toothed hole and the second inner locking tooth surface, respectively forming an engagement relationship, for adjusting the angle of the handlebar relative to the fork suspension.

2. The integrated handlebar adjustment structure with dual-axis adjustment as described in claim 1, wherein the first pivot locking group includes a first locking member, a first spindle post and a first stud, and the second pivot locking group includes a second locking member, a second spindle post and a second stud.

3. The integrated handlebar adjustment structure with dual-axis adjustment as described in claim 2, wherein the first toothed section and the first locking tooth surface of the first pivot locking assembly are formed on the first pair of locking members to engage with each other corresponding to the first toothed hole and the first inner locking tooth surface, respectively, and the second toothed section and the second locking tooth surface of the second pivot locking assembly are formed on the second pair of locking members to engage with each other corresponding to the second toothed hole and the second inner locking tooth surface, respectively.

4. The integrated handlebar adjustment structure with dual-axis adjustment as described in claim 2, wherein the first and second locking members are respectively provided with a first and a second annular groove, the first and second shafts are respectively inserted into the first and second annular grooves, and the first and second shafts are respectively provided with a first limiting member and a second limiting member, for the first limiting part and the second limiting part corresponding to the first and second annular grooves to engage with each other to limit the rotational displacement of the first and second shafts.

5. The integrated handlebar adjustment structure with dual-axis adjustment as described in claim 1, wherein the fork anchor has a countersunk hole extending along the fork steerer tube, through which a fork screw passes and is locked to a screw locking hole in the fork steerer tube.

6. The integrated handlebar adjustment structure with dual-axis adjustment as described in any one of claims 1 to 5, wherein the first and second inner locking tooth surfaces may be oblique conical, and the first and second locking tooth surfaces may be oblique conical corresponding to the first and second inner locking tooth surfaces, so as to form a mutually meshing toothed locking relationship.
