ABSTRACT:
The present invention relate to an adjusting device for adjusting a brake caliper toward the wheel rim of a bicycle so as to change the angle of the brake pad relative to the wheel rim.
BACKGROUND OF THE INVENTION
A conventional brake pad adjusting device known to applicant is disclosed in U.S. Pat. No. 5,960,913 having a title of “DEVICE FOR ADJUSTING THE BRAKE PAD RELATIVE TO THE WHEEL RIME OF A BICYCLE”. The U.S. Pat. No. 5,960,913 is invented by the applicant and is allowable, the Letter Patent of the application will be granted after the issue fee being paid. In the allowable application, the angle of the contact surface of a brake pad can be adjusted relative to the wheel rim by operating the actuating means, the cam member and the pushing member. The adjustment of the brake pad can only be made by moving the actuating means which is a bolt extending through the bottom of the frame portion of the brake caliper. Nevertheless, the thickness of the bottom of the frame portion is so thin so that the structural strength of the bottom will be weakened when a threaded hole is drilled through the bottom. Furthermore, the total weight of the brake caliper will be increased because the bolt extends through the bottom.
The present invention provides a device for adjusting the brake caliper to adjust the angle of the brake pad relative to the wheel rim without adding the total weight of the brake caliper.
SUMMARY OF THE INVENTION
A brake caliper adjusting device comprises a brake caliper comprising a frame and a head extending from the top of the frame portion. The frame has two sidewalls with a bottom connected therebetween and each of the sidewalls has an aperture defined therethrough for a shaft extending through the two apertures. The shaft has a threaded hole defined radially in one of two ends thereof. A supporting member has a brake pad connected thereto. A lug extends from a side of the supporting member and is pivotally received between the two sidewalls of the frame.
A cam member is fixedly mounted to the shaft and located between the two sidewalls of the frame. A pushing member is pivotally received between the two sidewalls of the frame. Two ends of the pushing member contacts the cam member and the supporting member.
An adjusting member is connected to the outside of the frame and rotatably mounted to the shaft. The adjusting member has a groove defined in one of two sides thereof. A lug extends from the other side of the adjusting member and has a slot defined therethrough. A biasing member has the first end thereof connected to the head of the brake caliper and the second end of the biasing member is received in the groove of the adjusting member. A bolt extends through the slot and is engaged with a threaded hole in the shaft.
The main object of the present invention is to provide a brake caliper adjusting device which has an adjusting member on a side of the frame of the brake caliper and the brake caliper can be rotated relative to the shaft by operating a bolt passing through the adjusting member and engaged with the shaft.
Further features of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.
