An improved stem for a bicycle comprises a column member having a top end, a first pivot mechanism and a second pivot mechanism which are provided on the two sides of the top end respectively; a sleeve member for fixing a handlebar, having a rod therefrom which defines a third pivot mechanism and a fourth pivot mechanisms on the two sides thereof; respectively and a lateral member including a left connecting part and a right connecting part wherein each of the left and right connecting part has two ends each having a protruded engaging mechanism adapted to be pivotally attached to the first, second, third and fourth pivot mechanisms so that the lateral member can be pivotally adjusted through the first and second pivot mechanisms, and the sleeve member can be pivotally adjusted through the third and fourth pivot mechanisms.

Stem for a bicycle

An improved stem for a bicycle comprises a pivot member having a lateral member and a locking member attached to the underside of the lateral member, wherein the pivot member has two free ends each having a pivot portion and the locking member has two free ends as well; a column member having a first connecting mechanism at the top thereof for pivotally connecting to the pivot portion; and a sleeve member securing a handlebar, and being provided with a second connecting mechanism at the free end thereof for pivotally connecting the other pivot portion of the pivot member, whereby the locking member can be operated to move so that each free end thereof is fixedly attached to or detached from the first connecting mechanism and the second connecting mechanism so as to achieve the adjustment of the angle between the column member and the pivot member, and the angle of the handlebar, at the same time.

An adjustable stem member comprises a vertical tube having a projected portion at one end thereof and a horizontal tube to be rotatably pivoted to the projected portion through a connecting mechanism at one end thereof. The connecting mechanism includes two tubular walls, an end wall and a space defined by the tubular walls and the end wall. A lower locking mechanism includes an upper locking block, a locking block and a bolt. The locking blocks are suitably disposed within the space. When the horizontal tube is adjusted to a suitable angle, the locking blocks are forced to press the end wall of the horizontal tube and the projected portion of the vertical tube.
