A bicycle brake cable tension adjustment device permits the adjustment of the brake cable only in one direction and limits the movement of the same in the other. The present disclosure includes a suspension member having a vertical wall and a horizontal wall on each of which is provided a through hole, and an adjustment assembly mounted on the horizontal wall of the suspension member and a cable fixing assembly mounted on the vertical wall of the same. The adjustment assembly includes a bolt-like member having a through hole in the axial direction which is provided with a tapered inner wall with the diameter thereof gradually increased from the top to the bottom, and a spring biased guiding tube having a conic bottom end with two or three symmetrically-located steel balls disposed in through holes defined on the periphery of the conic bottom end which is in corresponding abutment with the tapered surface of the bolt-like member. A brake actuating cable is guided through the bolt-like member and the the guiding tube and is in contact with the steel balls, therefore, once the guiding tube is moved upward against the inner tapered surface of the bolt-like member, the steel balls will be pushed radially inward to clamp on the brake actuating cable, restraining the same to move; and by pushing downward the spring biased guiding tube, the conic bottom end will disengage with the tapered surface so to release the cable from the clamping of the steel balls, permitting the same to be pulled in either direction for adjustment.
A brake force adjuster for a vehicle brake especially for a bicycle brake includes a hanger holding a hanging wire secured with a pair of brake shoes for operatively clamping a wheel rim of a vehicle wheel for braking purpose, an adjustable locking latch resiliently tensioned on the hanger normally frictionally locking a braking wire remotely connected to a brake lever to be operated by a vehicle driver, and a locking bolt locking the braking wire on the hanger. When unlocking the locking bolt and pulling the adjustable locking latch, the hanger may be freely moved along the braking wire for adjusting a clamping force of the braking shoes. After releasing the locking latch, the locking latch will resiliently frictionally lock the braking wire which is then firmly locked by the locking bolt also formed on the hanger. Therefore a brake force adjuster of a vehicle brake can be easily assembled and adjusted.
A hanger device is used to interconnect a pull cable and a yoke cable in a bicycle brake assembly and includes a vertical guide rod which is adapted to be mounted to a fork portion of a bicycle frame. A slidable member is mounted slidably on the guide rod and is adapted to be connected to the pull cable. The slidable member is formed with a transverse receiving groove that is adapted to receive an intermediate portion of the yoke cable therein.
A brake cable hanger assembly for connecting brake cables and a yoke cable of a bicycle brake mechanism includes a plate having a hole defined therethrough and a bent side extends from a lower end of said plate. Three protrusions split from said plate and define three apertures. A flange extends from a top end of said plate and two notches are defined in said flange. A positioning plate is engaged between said flange and said protrusions. A central hole is defined through said positioning plate. A bolt extends through said hole in said plate and said central hole in said positioning plate, and a nut is engaged with said bolt. Two brake cables extend through notches in the flange and are securely clamped between the positioning plate and the plate.
A dual cable force balancing mechanism for use with a pair of main brake cable segments and a pair of rear brake arms of a bicycle. The dual cable force balancing mechanism includes a brake arm actuation assembly defining a longitudinal axis positionable between the main brake cable segments. The brake arm actuation assembly is attachable to the rear brake arms. The dual cable force balancing mechanism further includes a pivot member including main attachment portions disposed about the longitudinal axis for respectively attaching the main cable segments. The pivot member is rotatably coupled to the brake arm actuation assembly for pivoting the pivot member with respect to the longitudinal axis.
