Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a spacer device for a parking brake used, for example, in a rotating part of a parking lever of an automobile.

In general, this type of parking brake spacer device is a gap formed between both sides of a rotating member that is rotated by operating a control lever and the inner surface of a bracket that is connected to this rotating member via a pin or the like. A spacer piece is interposed between each of the members to facilitate sliding between the rotating member and the bracket when the rotating member is rotated.

An operating wire for operating the brake is connected to the bracket, and when the rotating member is rotated by operating the operating lever, the operating wire moves back and forth through the pin and bracket to operate the brake. It looks like this.

However, in the prior art, each spacer piece was separate, so when the spacer pieces were assembled, each spacer piece had to be individually assembled, making the assembly work cumbersome.

Furthermore, since each spacer piece is assembled individually, there is a risk of forgetting to incorporate one of the spacer pieces.

In addition, if mud or dust adheres to each spacer piece, the movement between the rotating member and the bracket becomes unstable, and there is a drawback that it is difficult to remove mud or dust adhered to each spacer piece. .

Furthermore, when the rotating member, bracket, and each spacer piece are made of metal, if the rotating member is not operated often, the rotating member, bracket, and each spacer piece are likely to rust, and each spacer piece will not rotate. There is also a risk that the rotary member may be fixed to the movable member or the bracket, thereby interfering with smooth movement between the rotary member and the bracket.

The present invention was developed in view of the above circumstances, and its purpose is to integrate each spacer piece through a connecting part so that each spacer piece can be assembled at the same time with a single touch. When attaching a weight to the connection part, the vibration of the weight actively rotates each spacer piece to prevent mud and dust from adhering to it and from generating rust, and to always maintain smooth movement between the rotating member and the bracket. An object of the present invention is to provide a spacer device for a parking brake.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

In the figure, reference numeral 1 indicates the floor of an automobile, and a support plate 2 is fixed to this floor 1 with bolts 3, 3.

A rotating plate 5, which forms a triangular rotating member, is rotatably attached to the support plate 2 by a support shaft 4, and its lower end is inserted through a long hole 1a drilled in the floor 1. and is projected downward.

Further, an operating lever 6 is fixed to the upper end of the rotating plate 5, and a rod-shaped member 8 biased by a spring 7 is inserted into the operating lever 6.

Further, a locking lever 10 rotatably supported by a pin 9 is provided inside the operating lever 6, and the tip of the locking lever 10 is connected to a gear 11 formed on the support plate 2. It is designed to be locked in place.

On the other hand, a bracket 13 is rotatably connected to the lower end of the rotary plate 5 via a pin 12.
A gap 14, 14 is formed between the inner surface of the rotating plate 5 and both side surfaces of the rotating plate 5, respectively.

Further, a spacer device main body 15 is installed on the pin 12.

This spacer device main body 15 has spacer pieces 16.16 facing each other and spaced apart from each other, and each of these spacer pieces 16.16
are integrated by a connecting portion 17.

At the center of each spacer piece 16, 16 is the pin 12.
A through hole 18 is bored through the hole.

Furthermore, the connecting portion 17 includes two opposing surface portions 29.29 extending from each spacer piece 16.16 to project from the bracket 13 and the rotating plate 5 in the radial direction of each spacer piece 16. It consists of a bottom part 30 that connects the edges, and is formed to have a generally U-shaped cross section as a whole.

Further, a weight 28 that partially covers the spacer device main body 15 is attached to the bottom surface 30 of the connecting portion 17.

Next, to explain how to attach the spacer device main body 15, first, attach the lower end of the rotating plate 5 to the bracket 13.
At this time, gaps 14 and 14 are formed between the inner surface of the bracket 13 and both side surfaces of the rotating plate 5.

Thereafter, each spacer piece 16.16 of the spacer device main body 15 is inserted into the gap 14.14 to open the through hole 1.
8.18 through each through hole 5 of the rotating plate 5 and the bracket 13
a, 13a, and 13a, respectively.

From this state, the through hole 13a of the bracket 13 is
Insert the pin 12 into the spacer piece 16.16, the rotating plate 5, and the respective through holes 16a, 16 of the bracket 13.
a.

5a, 13a to protrude, and the stopper 19 is attached to the protruding end to complete the installation.

On the other hand, a brake operating section 21 is connected to the bracket 13 via an operating wire 20 that moves forward and backward as the rotating plate rotates.

Therefore, in the above-mentioned stealing, the rod member 8 is pressed against the urging force of the spring 7, the locking lever 10 is separated from the gear 11 of the support plate 2, and the operating lever 6 is rotated counterclockwise. As a result, the rotating plate 5 rotates while sliding along the surface of each spacer piece 16, 16 using the support shaft 4 as a fulcrum.

As a result, the operating wire 20 is pulled through the pin 12 and the bracket 13, and the brake actuating section 21 is operated.

Further, when the locking lever 10 is disengaged from the gear 11 and the operating lever 6 is rotated clockwise, the rotating plate 5 is also rotated clockwise.

As a result, the operation wire 20 is pushed back via the pin 12 and the bracket 13, and the operation of the brake actuator 21 is released.

As described above, each spacer piece 16.16 interposed between the rotating plate 5 and the bracket I/13 is integrated by the connecting part 17, so when the spacer device main body 15 is assembled, each spacer piece 16.16 is It becomes possible to incorporate all of them at the same time with one touch, without having to incorporate them individually.

Furthermore, even if dirt or dust adheres between the rotating plate 5 and the spacer piece 16.16, the weight 28 will vibrate to the left or right in FIG. Since it rotates, mud, dust, etc. can be removed.

In addition, since the weight 28 vibrates due to the vibration of the automobile, rust etc. may occur between the spacer piece 16, 16 and the rotating plate 5 even if there are few opportunities to rotate the rotating plate 5. This makes it possible to prevent the spacer piece 16° 16 from sticking to the rotating plate 5.

Further, the spacer device 15 is not limited to the rotating part of a parking lever, but can also be employed in a rotating part of a clutch lever of an automobile.

As explained above, in the present invention, each spacer piece is integrated by a connecting part, and a weight is attached to the connecting part, so that each spacer piece can be inserted into the plurality of gaps formed between the operating member and the bracket with one touch. Therefore, the installation work can be simplified and carried out reliably.

Furthermore, even if mud, dust, etc. adhere to each spacer piece, the vibration of the car causes the weight to vibrate and the spacer piece to rotate.
It can remove mud, dust, etc.

In addition, even if there are few opportunities to operate the rotating member because the weight vibrates due to the vibrations of the automobile, the spacer device will not cause rust etc. to occur between the spacer device main body and the rotating member and bracket. This provides many practical effects such as being able to effectively prevent the main body from sticking to the rotating member and the bracket.
