Abstract
A foot depressing parking brake apparatus including a brake pedal main body 3 pivotably supported by a support shaft 2, a ratchet plate 4 having ratchet teeth 4b and attached to the brake pedal main body 3, a ratchet pole 6 rotatably attached to a pivot pin 5 and constituting a shaft hole inserted with the pivot pin 5 by a long hole 7, and a toggle spring 10 for exerting a turning force to the ratchet pole 6, wherein a brake operating state in which a claw portion 6a of the ratchet pole 6 is brought in mesh with the ratchet teeth 4b of the ratchet plate 4 and a brake releasing state in which the meshing is released are realized.
Claims7
A foot depressing parking brake apparatus comprising:
- a brake pedal main body pivotably supported by a support shaft,
- a ratchet plate having ratchet teeth and attached to the brake pedal main body,
- a ratchet pole rotatably attached to a pivot pin and constituting a shaft hole thereof inserted with the pivot pin by a long hole, and
- an elastic member for exerting a turning force to the ratchet pole,
- wherein by sliding the ratchet pole along the shaft hole constituting the long hole by the turning force by the elastic member and
- a force of depressing the pedal main body,
- a brake operating state in which
- a claw portion of the ratchet pole is brought in mesh with the ratchet teeth of the ratchet plate, and
- a brake releasing state in which the meshing is released are realized, the ratchet plate is integrally provided with a reset arm portion having an engagement surface that is selectively engaged by the ratchet pole for restricting an attitude of the ratchet pole in releasing a brake,
- wherein the engagement surface is defined by a bent portion and an escaping portion separated from each other by a projection disposed therebetween.
A foot depressing parking brake apparatus comprising:
- a brake pedal main body pivotably supported by a support shaft,
- a ratchet plate having ratchet teeth and attached to the brake pedal main body,
- a ratchet pole rotatably attached to a pivot pin and constituting a shaft hole thereof inserted with the pivot pin by a long hole, and
- an elastic member for exerting a turning force to the ratchet pole,
- wherein by sliding the ratchet pole along the shaft hole constituting the long hole by the turning force by the elastic member and
- a force of depressing the pedal main body,
- a brake operating state in which
- a claw portion of the ratchet pole is brought in mesh with the ratchet teeth of the ratchet plate, and
- a brake releasing state in which the meshing is released are realized, the ratchet plate is integrally provided with
- a reset arm portion for restricting an attitude of the ratchet pole in releasing a brake, and
- a base end portion of the reset arm portion is formed with an escaping portion in correspondence with the sliding operation in releasing the brake, and
- a stopper for restricting rotation of the ratchet pole in the meshing direction, and a stopper for restricting rotation thereof in a direction reverse thereto.
