ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a brake cable positioning assembly for an inner swivel connector of a free style bicycle, especially to a brake cable positioning assembly capable of conveniently and exactly positioning the brake cables between the handlebar grip and the inner swivel connector.
2. Description of Related Art
A swivel connector is mound around the fork shaft of a free style bicycle and is used to connect the brake cables between the handlebar grip and the rear brake to allow 360° revolution of the handlebar without wrapping the brake cables around the fork shaft and the frame. The swivel connector is usually mounted around the outer periphery of the fork shaft. The problem of surface corrosion of the swivel connector occurs due to environmental factors such as oxidation, moisture in the air or acid rain. A proposal for resolving the problem of corrosion of the swivel connector is to provide an inner swivel connector inside the head tube, for example the inner connector as shown in FIG.

.
With reference to
FIG. 4
, a swivel connector
50
is rotatably mounted around the tubular fork shaft
41
with one end connected to the front fork
40
and the other end inserted into the handlebar clamp
20
. The head tube
30
is mounted between the front fork
40
and the handlebar clamp
20
over the swivel connector
50
. The upper head set
31
is further provided between the handlebar clamp
20
and the head tube
30
to facilitate the rotation of the handlebar clamp
20
. In order to connect the brake cable
51
from the handle grip (not shown) to the inner connector
50
, the shank
201
extending between the two bores (one for receiving the handlebar and the other for receiving the fork tube) on the handlebar clamp
20
is drilled to form a cable
51
passage. The head set
31
is also drilled to receive the cable
51
. Since the shank
201
is very thick and the head set
31
should be punctured such that the puncture on the clamp
20
aligns with that on the head set
31
, a new problem regarding fabrication and assembly time and cost arises with the device as shown in the prior art.
Therefore, there is a need for a brake cable positioning assembly capable of conveniently and exactly positioning the brake cable between the handlebar grip and the inner swivel connector.
SUMMARY OF THE INVENTION
The objective of the present invention is to provide a brake cable positioning assembly for an inner swivel connector on a free style bicycle, which can conveniently and exactly position the brake cable between the handlebar grip and the inner swivel.
To achieve the objective, the brake cable positioning assembly in accordance with the present invention contains a mounting element for connecting the handlebar clamp with the fork shaft. The mounting element has a lug inserted into the slit extending between the periphery of the bore for clamping the fork shaft and the edge of the handlebar clamp. The mounting element further has a sleeve to receive the brake cable fitting. With the assembly disclosed, the brake cable can travel to the inner swivel connector through the slit without penetrating the shank of the handlebar clamp.
