Abstract: In a parking brake system, a locking tooth of a ratchet plate includes a first area for contacting and retaining a locking claw of a ratchet pawl in an equilibrium state when a parking brake lever is pulled up; and a second area in which the locking claw remains in a state of halfway engagement of tooth tips when a pressing force of a release rod is released. When the locking claw comes into contact with a portion closer to a tip of the locking tooth beyond the first area, a line of force is maintained due to the pressing force of the release rod. The system is configured such that even if an occupant erroneously pulls up the parking brake lever while the release rod is pressed, it is possible to reliably prevent halfway engagement of tooth tips in a ratchet mechanism.

Abstract: In a parking brake system, a locking tooth (17a) of a ratchet plate (17) is configured to have: a first area (S1) in which a locking claw (19c) of a ratchet pawl (19) comes into contact with the locking tooth and remains there in an equilibrium state when a parking brake lever is pulled up and thereafter loosened while a release rod being pressed; and a second area (S2) in which the locking claw remains there in a state of halfway engagement of tooth tips when a pressing force of the release rod is released. With this configuration, when the locking claw (19c) comes into contact with a portion closer to a tip of the locking tooth (17a) beyond the first area (S1), a line of force (F1) is maintained due to the pressing force of the release rod. Accordingly, the locking claw (19c) does not become in the state of halfway engagement of tooth tips at the second area (S2), and the locking claw (19c) slides towered the tooth tip to prevent beforehand the occurrence of the state of halfway engagement of tooth tips.

Abstract: A base frame 1 is such as to be fixedly provided on a body so that a parking brake device 2 is provided thereon which causes a brake applying portion of a parking brake to apply the brake and release the brake so applied, a base frame main body 1a is molded into an integral unit, a parking device mounting portion 10A where the parking brake device 2 is mounted is formed on one side A of the base frame man body 1a, and a gearshift device mounting portion 10B where a gearshift device of a transmission is provided is formed on the other side B thereof.

Abstract: A lever 2 includes first and second lever members 10, 20 between which both sides of a base B are interposed. A guide piece 14, which is a part of first lever member 10 arranged on first side of the base B, is formed being located on a second side of the base B. The guide piece 14, which is a part of the first lever member 10 located on the second side, has a guide portion to guide a wire 4 together with a guide piece 24 formed in the second lever member 20.

Abstract: A man-powered braking apparatus which uses rocking motion to switch over between the braking state and the releasing state, assures smooth operation, and minimizes the reduction in braking force when the braking lever is returned. When the force to the braking lever 20 is removed, the braking state in which the pawl member 40 is engaged with the ratchet plate 12 is maintained. When the force is removed, the power transmission pin 25 is moved, being kept fitted into the cam groove 52 in the transmission link member 50, and is shifted from the force transmission cam groove 53 to the release holding cam groove 54, the transmission link member 50 being turned to the releasing position, and the pawl member 40 is brought into the state in which it is energized in the direction for being disengaged from the ratchet plate 12 while the braking state being maintained.

Abstract: A parking brake apparatus has a base, a ratchet plate fixed to the base, an operation lever includes a rotational base portion pivotally supported on the base; a pawl adapted to engage/disengage with the ratchet plate; an arc-shaped intermediate member comprises an arc-shaped relay rod; and a grip for controlling the engagement of the pawl. The arc-shaped relay rod is divided into at least two and is made to be interlocked with operations by the grip to transmit an engagement/disengagement operation with the ratchet plate to the pawl, the ratchet plate and the rotational base portion are provided inside a body side mounting portion, and the intermediate member is provided in such a manner as to appear from and disappear into a passage hole in the body side mounting portion.

Abstract: A parking brake apparatus includes: an operating handle including an operating pushbutton; a base bracket including a ratchet plate having a ratchet; a brake cable for actuating a brake when the operating handle is pulled along a longitudinal direction of the base bracket; and a shaft retained in the base bracket and having a base end part fixed to the operating handle and a nose part connected to the brake cable. The shaft includes a seizing and releasing mechanism connected to the brake cable and having a seizing pawl for seizing and releasing the ratchet, and a releasing mechanism connected to the operating handle and having a release pawl for reorienting the seizing pawl seizing the ratchet through the operating pushbutton to release the seizing pawl from the ratchet.
