Description

[Detailed Description of the Invention] Technical Field The present invention relates to a floor type parking brake operating device.

Prior Art Conventionally, a control lever is rotatably provided on the floor near the driver's seat of a vehicle, and a cylindrical grip is integrally fixed to the tip of the control lever so as to cover the tip. A floor-type parking brake operating device is provided which includes a release knob that protrudes from the end surface of the grip and is pushable into the grip. To release the parking brake in such a device, normally, hold the grip of the operating lever located at the brake activation position with your fingers other than your thumb, lift the operating lever slightly, and use the tip of your thumb to press the release knob. By pushing in, the operating lever is allowed to rotate in the direction of releasing the parking brake.

Problems to be Solved by the Invention However, in such a floor-type parking brake operating device, the center of the pressing surface of the release knob is usually approximately aligned with the axis of the grip. The tip is usually located close to the base of the index finger hooked on the grip, and in this condition it is relatively difficult to apply force to the thumb when pushing the release knob with the thumb. It was. Therefore, in the past, it was not always easy to release the parking brake using the floor-type parking brake operating device.

Means for Solving the Problems The present invention was developed against the background of the above circumstances, and its purpose is to provide a floor-type parking brake operating device that makes it easier to release the parking brake. It is in. In order to achieve this object, the present invention provides a floor-type parking brake operating device as described above, in which the center of the pressing surface of the release knob is eccentrically positioned toward the driver's seat side with respect to the axis of the grip. Features.

Function and Effects of the Invention By doing this, the center of the pressing surface of the release knob is eccentrically moved toward the driver's seat side with respect to the axis of the grip, so when releasing the parking brake, the pressing surface of the release knob The thumb pressing the grip can be moved farther from the base of the index finger hooked on the grip toward the driver's seat side than before. This makes it easier to apply force to the thumb when pushing the release knob with the thumb, making it easier to release the parking brake than in the past.

Embodiment Hereinafter, an embodiment of the present invention will be described in detail based on the drawings.

FIG. 3 is a diagram showing a floor type parking brake operating device to which the present invention is applied. In the figure, a parking brake operating lever 16 is mounted on a bracket 14 fixed to the floor 12 next to the driver's seat 10 (see FIGS. 1 and 2) in the vicinity of the driver's seat 10 of the vehicle. It is rotatably mounted on a shaft 18 across a bracket 14, and a plurality of engagement teeth 20 are formed on the bracket 14 along an arc centered on the shaft 18. A parking cable 22 is connected to a position on the base end side of the operating lever 16 and a predetermined distance away from the shaft 18, which allows the operating lever 16 to be moved in the parking brake operating direction (clockwise in FIG. 3). When turned to , the parking cable 22 is pulled in to the left in FIG. 3, and the parking brake is activated. A pawl 2 having a claw portion 24 at one end is provided at the longitudinally intermediate portion of the operating lever 16.
6 is rotatably attached at the intermediate portion by a pin 28, and a cylindrical resin grip 30 is integrally fixed to the tip of the operating lever 16 so as to cover the tip. There is.

A release knob 32 having an overall cylindrical shape is fitted into the tip of the operating lever 16 and protrudes by a predetermined distance and is prevented from protruding beyond a certain limit by the grip 30. The release knob 32 and the pawl 26 The other end is connected to the other end via a connecting rod 34. The release knob 32 is always urged in the protruding direction according to the urging force of a compression coil spring 36 inserted between it and the operating lever 16, and the release knob 32 is always urged in the projecting direction according to the urging force of the compression coil spring 36. is the claw part 24
is constantly biased in the rotating direction (counterclockwise direction in FIG. 3) in which it engages with the engaging teeth 20. As a result, when the operation lever 16 is rotated in the direction of operating the parking brake, the pawl 26 repeatedly rotates back and forth at a small angle, and the pawl 24 moves toward the engagement tooth 2.
0 and allows the operating lever 16 to rotate, while preventing the operating lever 16 from returning from the operating position based on the engagement between the claw portion 24 and the engagement teeth 20. It should be noted that the return rotational position (original position) of the operating lever 16 is regulated by a stopper (not shown).

In this embodiment, as shown in FIG. 2, the thickness of the grip 30 on the side opposite to the driver's seat 10 is made thicker by a predetermined amount than the thickness on the driver's seat 10 side. As a result, the release knob 3
2 axis O1, that is, the pressing surface 38 of the release knob 32
As shown in FIGS. 1 and 2, the center of the grip 30 is offset by a distance L toward the driver's seat 10 from the axis O2 of the grip 30. This eccentric dimension L is
Usually, the size is set to about several mm. As a result, when releasing the parking brake,
When a finger other than the thumb 40 is hooked onto the grip 30 of the operating lever 16 located at the operating position, as shown in FIG. (Forefinger 4
It will be located at a position relatively distant from the distal end side of No. 2). As a result, when pushing the release knob 32 with the thumb 40, the thumb 40
The movement becomes natural and it becomes easier to apply force to the thumb 40, making it easier to release the parking brake than in the past.

In addition, in the above-mentioned embodiment, the grip 30
By making the wall thickness on the side opposite to the driver's seat 10 thicker than the wall thickness on the driver's seat 10 side, the axis O1 of the release knob 32 (the center of the pressing surface 38) can be moved more easily than the axis O2 of the grip 30. Although it is eccentric to the seat 10 side, it does not necessarily have to be configured that way.
For example, as shown in FIG. 4, even if the axis O1 of the release knob 44 substantially coincides with the axis O2 of the grip 46, the tip of the release knob 44 may
The center O3 of the pressing surface 50 of the release knob 44 may be made eccentric toward the driver's seat 10 side with respect to the axis O2 of the grip 46 by providing the protruding portion 48 that protrudes toward the zero side. The small diameter portion that is the protruding portion of the release knob 32 may be shifted toward the driver's seat 10 side relative to the large diameter portion of the release knob 32 that is fitted to the operating lever 16.

In addition, various changes may be made to the present invention without departing from the spirit thereof.
