Abstract
An apparatus for use on bicycles having a front brake, a rear brake, a left hand brake lever and a right hand brake lever wherein, regardless of whether the left or right hand brake lever is actuated, or both brake levers simultaneously, the rear brake of the bicycle is preferentially actuated such that the rear brake is applied first and with more force than the front brake. The apparatus includes a housing for mounting on the bicycle, a front brake actuator connected to a cable extending to the front brake and a rear brake actuator connected to a cable extending to the rear brake one of the actuators having two pulleys thereon, each of the cables from the brake levers looping around the pulleys and attaching to the other brake actuator, and including a spring applying a bias to resist the movements of the front brake actuator.
Claims5
A safety brake device for bicycles having a right brake lever with a right lever cable extending therefrom which is drawn towards the lever when the lever is actuated, a left brake lever having a left lever cable extending therefrom which is drawn towards the lever when the lever is actuated, a front brake having a front brake cable extending therefrom, the front brake being actuated when the front brake cable is drawn away from the brake, and a rear brake having a rear brake cable extending therefrom, the rear brake being actuated when the rear brake cable is drawn away from the brake, the device comprising:
- a housing supported to the bicycle having said right and left lever cables and said front and rear brake cables communicating therewith;
- a front brake actuator movably supported in said housing, said front brake cable being connected to said front brake actuator, said front brake actuator being movable between a first position in which said front brake is not applied and a second position wherein said front brake cable is withdrawn to apply said front brake;
- a rear brake actuator movably supported in said housing, said rear brake cable being connected to said rear brake actuator, said rear brake actuator being movable between a first position in which said rear brake is not applied and a second position wherein said rear brake cable is withdrawn to apply said rear brake;
- two pulleys being rotatably affixed to one of said front and rear brake actuators, said right lever cable looping around one of said pulleys and the end thereof being affixed to the other of said actuators, and in like manner, the left lever cable being looped around the other pulley and attached to the other of said actuators;
- and
- means biasing said rear brake cable in preference to said front brake cable whereby said rear brake cable will be withdrawn towards said housing first when either said right or left brake lever is applied.
