Description

[Detailed description of the invention] [Industrial application field] This invention is a model in which the inner cable connected to the parking brake is rolled up and the parking brake is activated by stepping on a foot lever equipped with a foot pedal. This invention relates to a foot-operated parking brake device.

[Prior Art] A foot-operated parking brake device in which the parking brake is actuated by pressing a foot pedal and released by pulling a release knob is well known (for example, in the 59-135260),
It is also used in actual cars.

In this type of foot-operated parking brake device, a strong tensile force acts on the parking brake cable while the parking brake is applied, so the end of the outer cable of the parking brake cable is fixed and supported on the foot lever side. There is also the problem that excessive force is applied to the mounting bracket.

[Purpose of the invention] An object of the invention is to provide a foot-operated parking brake device that can safely support a parking brake cable by adding an ingenuity to the parking brake cable support structure.

[Structure of the invention] For this reason, the invention includes a foot lever whose base is pivoted between a pair of side walls of the mounting bracket, and by stepping on the foot lever, the parking brake whose one end is connected to the parking brake side can be operated. In a foot-operated parking brake device in which the inner cable is rolled up to activate the parking brake, a mounting bracket is provided on the bottom surface of the mounting bracket between the pair of side walls, and the end of the parking brake cable is tied to a certain length. A flexible pipe-shaped connector is provided that is fitted concentrically across the cable and is curved to match the wiring shape of the parking brake cable, and this connector is fixed to the mounting bracket at one end using a support bracket. It is characterized by the fact that

[Effects of the invention] According to the invention, the parking brake cable is supported by being fitted into a connector made of a flexible pipe curved to match the wiring shape of the parking brake cable,
This connector was fixed at one end between the mounting bracket and the support bracket, so that
The force acting on the parking brake cable can be transmitted to the mounting bracket in a state where it is distributed throughout the connector, preventing stress from being concentrated locally and preventing excessive force from concentrating on the mounting bracket. be done.

Furthermore, according to the present invention, the parking brake cable is fitted concentrically with the connector and its movement is restricted by the connector, so even when the parking brake is applied, the curved part of the parking brake cable inside the connector will not move. There is no movement, and the braking force of the parking brake is stable.

Furthermore, according to the present invention, since the connector to which the parking brake cable is fitted is curved to match the wiring shape of the parking brake cable, the parking brake cable can be given directionality by curving the connector. , the ease of assembling the parking brake cable is improved. When assembling the parking brake cable, if the connector is fixed to the support bracket in advance, the parking brake cable can be set simply by fixing the support bracket to the mounting bracket, further improving assembly efficiency. do.

0a enters inside through a window 3a formed in the side wall member 3 and engages with the ratchet lever 9 from the unlocking direction.

The lock release lever 10 has an extension part 10b that extends obliquely downward from a support shaft 13 that rotatably supports the lock release lever 10, and one end of the inner cable 11a of the release cable 11 is attached to the extension part 10b. Fixed.

Note that the foot lever 5 is hooked to one end of each return spring 14, 15, 16 through a spring receiver 5c, and the ratchet lever 9 and lock release lever 10 are hooked directly to each spring receiver. It is biased in the return direction.

Further, the upper end of an adjustment rod 18 is connected to the end of the counter lever 8 opposite to the cable winding part via a connecting fitting 17.
A guide bracket 19 is provided on the foot lever 5.
A nut 20 is screwed into the threaded portion at the bottom of the adjustment rod 18 and is guided so as to move forward and backward in the axial direction.
Tighten and adjust the counter lever 8.
It is preferable that the initial position of the device is adjustable. If such an adjustment mechanism is provided, the locking member 2
The winding start position of the parking brake cable 7, which is locked through the parking brake cable 7, can be adjusted according to the slackness of the inner cable 7a of the parking brake cable 7, and the effectiveness of the parking brake can be adjusted.

As clearly shown in FIG. 1, the operating mechanism is provided with a cover member 22 for protecting the mechanism.
will be established. This cover member 22 includes a first cover portion 2 that covers the upper openings of the pair of side wall members 3 and 4.
2a, and a second cover portion 22b that extends outside one side wall member 3 that supports the lock release lever 10 so as to cover the lock release lever 10 from the outside.
The first cover part 22a is a sheet metal member integrally formed with the other side wall member 4, and the first cover part 22a is attached to the bracket 4a provided on the upper edge of the other side wall member 4 with screws 23, 23, . As shown in FIG. 2, the left and right ends are fixed to one side wall member 3 at a predetermined distance with screws 24, 24 via spacers (not shown).

By providing such a cover member 22, small items will not fall between the pair of side wall members 3 and 4.
Further, the lock release lever 10 does not interfere with the air conditioning duct or various wirings.

Next, the wiring structure of the parking brake cable 7 and the release cable 11 will be explained.

As shown in FIG. 2, the outer cable 7b of the parking brake cable 7 has its end connected to the lower surface between the pair of side wall members 3 and 4, more specifically,
