Abstract
A foot brake release device adapted such that a slight and instant pull of a parking release knob for releasing a parking activated state for a parking brake pedal enables the complete release of the parking activated state of the parking brake pedal. The device includes a parking brake pedal equipped at one side thereof with a ratchet gear; a ratchet plate equipped with a ratchet gear meshed to a ratchet gear; a torsion spring mounted at the ratchet plate allowing the parking brake pedal to rotate at a predetermined angle for maintenance of a locked state and to restrict the ratchet plate from rotating in one direction; and a torsion spring slack keeping unit for maintaining a slacked state of the torsion spring when the parking brake pedal is returned for rotation.
Claims4
A foot brake release device, the device comprising:
- a rotatably mounted parking brake pedal having at one side thereof a ratchet gear, the brake pedal moveable back and forth between a parking brake locked state and a parking brake unlocked state;
- a rotatably mounted ratchet plate having a ratchet gear meshed to the ratchet gear of the break pedal;
- a torsion spring mounted at the ratchet plate allowing the parking brake pedal to rotate at a predetermined angle, wherein the torsion spring maintains a locked state of the parking brake pedal and restricts rotation of the ratchet plate in one direction;
- and
- torsion spring slack keeping means for maintaining a slacked state of the torsion spring when the parking brake pedal is returned from the parking brake locked state, wherein the torsion spring slack keeping means further comprises,
- a hinge member,
- a lock lever mounted with a first bend rotatively connected to the hinge member and contactable to the ratchet plate,
- a second bend extended to contact a free end of the torsion spring, and
- a resilient member mounted at the lock lever for resiliently supporting the lock lever.

- and
- torsion spring slack keeping means for maintaining a slacked state of the torsion spring when the parking brake pedal is returned from the parking brake locked state, wherein the torsion spring slack keeping means comprises,
- a hinge member,
- a lock lever having a first portion rotatably coupled to the hinge member for contacting the ratchet plate and a second portion for contacting a free end of the torsion spring, and
- a resilient member mounted on the lock lever for resiliently supporting the lock lever.
