Abstract

A bicycle stem having a positioning mechanism for re-positioning a handle comprises a vertical tube; an adaptor having a bore and an extension, wherein the bore receives therein the vertical tube so that the adaptor can rotate about the vertical tube; a lateral tube with a front end having a clamp for locking the handle, and a rear end pivotally connected to the extension of the adaptor; and a positioning mechanism comprising a rod for fixing the adaptor on the vertical tube as the adaptor is rotated to the required position about the vertical tube.

Claims

1. A bicycle stem having a positioning mechanism for re-positioning the bicycle handle, comprising:

a vertical tube;

an adaptor having a bore and an extension, wherein said bore receives therein said vertical tube so that the adaptor can rotate about the vertical tube; and

a lateral tube with a front end having a clamp for locking said handle, and a rear end pivotally connected to said extension of said adaptor;

characterized by further including a positioning mechanism, said positioning mechanism comprising a rod for fixing the adaptor on the vertical tube as said adaptor is rotated to the required position about the vertical tube.

2. A bicycle stem having a positioning mechanism for re-positioning a handle as claimed in claim 1, wherein said positioning mechanism further includes two positioning holes which are for insertion of said rod and preferably form a 90-degree angle therebetween.

3. A bicycle stem having a positioning mechanism for re-positioning a handle as claimed in claim 1, wherein said positioning mechanism further includes an aperture provided longitudinally on said extension of said adaptor, said rod being inserted in said aperture, and a compression spring being sleeved on said rod.
