Abstract

A one-piece connector for a shock-absorbing frame of a bicycle is manufactured by casting, forging or high pressure hydraulic forming means, is made of aluminum and formed as a single piece without welding, and has a bottom bracket shell, a connecting tube, a pivot and a linking joint. The connecting tube is formed on and protrudes from a top surface of the bottom bracket shell. The pivot is formed with the connecting tube near the bottom bracket shell. The linking joint is formed on an upper end of the connecting tube. The bottom bracket shell, the connecting tube, the pivot and the linking joint are formed with each other to form the one-piece connector without welding to simplify the production process, to improve the precision, quality and appearance of the one-piece connector, and to reinforce the structural strength of the one-piece connector.

Claims

1. A one-piece connector for a shock-absorbing frame of a bicycle, the one-piece connector being manufactured by casting, forging or high pressure hydraulic forming means, being made of aluminum and formed as a single piece without welding, and having:

a bottom bracket shell being a transversal tube and having a top surface;

a connecting tube formed on and protruding from the top surface of the bottom bracket shell and having an upper end;

a pivot formed with the connecting tube near the bottom bracket shell; and

a linking joint formed on the upper end of the connecting tube.

2. The one-piece connector for a shock-absorbing frame of a bicycle as claimed in claim 1, wherein the one-piece connector has a cylinder mount formed on and protruding from a front side of the connecting tube.

3. The one-piece connector for a shock-absorbing frame of a bicycle as claimed in claim 2, wherein the cylinder mount has two connecting wings formed on and protruding from the front side of the connecting tube and being parallel to each other, and each one of the connecting wings has a central protruding portion and a connecting hole formed through the central protruding portion of the connecting wing.

4. The one-piece connector for a shock-absorbing frame of a bicycle as claimed in claim 3, wherein the one-piece connector has a front transmission formed on and protruding from a rear side of the connecting tube.

5. The one-piece connector for a shock-absorbing frame of a bicycle as claimed in claim 4, wherein the pivot is a transversal tube, the connecting tube is a closed tube, and the linking joint is a hollow tube.

6. The one-piece connector for a shock-absorbing frame of a bicycle as claimed in claim 4, wherein the pivot is composed by two parallel boards, the connecting tube is a hollow tube and has an opening formed through the upper end of the connecting tube, and the linking joint is a hollow tube.

7. The one-piece connector for a shock-absorbing frame of a bicycle as claimed in claim 3, wherein the pivot is a transversal tube, the connecting tube is a closed tube, and the linking joint is a hollow tube.

8. The one-piece connector for a shock-absorbing frame of a bicycle as claimed in claim 3, wherein the pivot is composed by two parallel boards, the connecting tube is a hollow tube and has an opening formed through the upper end of the connecting tube, and the linking joint is a hollow tube.
