Description

[Detailed description of the invention] This invention relates to a safety device for the stick-type parking brake installed in automobiles.The purpose of this invention is to reduce the impact when an excessive load is applied to the parking brake handle. An object of the present invention is to provide a safety device for a parking brake that can improve driver safety.

Next, an embodiment of the present invention will be described with reference to the drawings. In the drawing, reference numeral 1 denotes a support bracket for a parking brake P that is tilted near the driver's seat at the front of the vehicle, and has a substantially flat side surface S. formed into a mold shape,
And, the cross section is formed into a substantially square shape, and the inner end 1
Elongated inner slide holes 2 are formed opposite each other in the longitudinal direction on both sides near a, while elongated outer slide holes 3 are formed on both sides near the outer end 1b. They are opened opposite each other along the longitudinal direction.

Reference numeral 4 denotes an inner connecting pin that is slidably fitted laterally into the inner slide hole 2, and 5 is an outer connecting pin that is slidably fitted laterally into the outer slide hole 3.

A regulating piece 6 is fixed to the right side surface of the outer end 1b of the support bracket 1 near the inner end of the outer slide hole 3, and controls the inner slide end position of the outer connecting pin 5.

Reference numeral 7 denotes a connecting piece, the upper end 7a of which is movably connected to the inner end 1a of the support bracket 1 via an inner connecting pinch, while the lower end 7
b extends inwardly in a downwardly inclined manner.

Reference numeral 8 denotes an operation bracket arranged in parallel so as to be movable forward and backward with respect to the lower part of the support bracket 1, and an inner end 8b inside a base 8a formed in a substantially round pipe shape is connected to a lower end 7b of the connecting piece 7. While fixed integrally, the outer end 8c of the base 8a is connected to the outer connecting pin 5.
The base portion 8a is connected to the outer end portion 1b of the support bracket 1 via the support bracket 1, and a guide groove 9 is formed in the upper surface of the base portion 8a.

Reference numeral 10 denotes an operating shaft that is rotatably and slidably fitted to the base 8a of the operating bracket 8, and is connected to the support bracket 1 through the operating bracket 8.
The inner end 10a of the
has a handle 11 attached to it, while its outer end 10
A brake cable 12 connected to a brake device (not shown) is connected to b.

Reference numeral 13 denotes a stopper protruding from the upper surface near the outer end 10b of the operating shaft 10, which
The guide groove 9 of the operating bracket 8 is engaged in order to regulate the relative position of the operating shaft 10 with respect to the operating bracket 8.

Reference numeral 14 denotes a spring hung between the right side edge of the inner end 1a of the support bracket 1 and the outer connecting pin 5, and the outer connecting pin 5 is normally connected to the outer slide hole 3.
At the same time, the operating shaft 10 is urged inwardly through the operating bracket 8 to be held in a permanent position.

Reference numeral 15 denotes a bifurcated cable bracket fixed to the outer end of the operation bracket 8. A guide plate 16 is rotatably supported inside near the center of the cable bracket through a pin 17, and the lower end of the cable bracket 15 is a bifurcated cable bracket. A flexible tube 18 surrounding the brake cable 12 is provided in the section.
is connected.

Next, the operation and effects of the embodiment having the above configuration will be explained.

Now, in this example, the support bracket 1 of the parking brake P tilted inside the vehicle is connected to the support bracket 1 through the inner and outer connecting pins 4 and 5 that are guided to the inner and outer slide holes 2 and 3 that are opened along the longitudinal direction of the support bracket 1. The operating bracket 8 and the operating shaft 10 fitted to the operating bracket 8 are arranged side by side so that they can move forward and backward, and the operating bracket 8 and the operating shaft 10 are always elastically movable relative to the permanent position with a spring 14. Therefore, even if an excessive load is applied to the handle 11 of the operating shaft 10 by the driver's knee or the like during a sudden stop, the operating shaft 10 and the operating bracket 8 will be able to resist the elastic force of the spring 14. As a result of being elastically retracted via the inner and outer connecting pins 4 and 5, which are guided by the inner and outer slide holes 2 and 3 and retracted, the load applied to the knees and the like can be absorbed and the safety for the driver can be increased. There is.

When the impact on the operating shaft 10 is removed, the inner and outer connecting pins 4 and 5 are urged by the expanded spring 14 and move inward through the inner and outer slide holes 2 and 3, and the operating bracket 8 and the operating When the shaft 10 returns to the permanent position and is held at this permanent position, the operability of the brake device can be ensured.

Furthermore, even when the operating bracket 8 and the operating shaft 10 elastically retract when the brake device is activated, the relative positions of the operating shaft 10 and the brake cable 12 with respect to the operating bracket 8 are maintained, so that there is no excessive force on the handle 11 of the parking brake. This has the effect of preventing the brake device from being released inadvertently even when a heavy load is applied.

That is, the present invention connects the operating bracket and the brake to the operating bracket through a connecting pin guided through a slide hole formed along the longitudinal direction of the supporting bracket of the parking brake tilted inside the vehicle. By arranging the operating shafts that are operably fitted so that they can move forward and backward, and by always holding the operating bracket and the operating shaft in a permanent position so as to be able to move elastically back and forth using a spring. , the driver's safety can be improved by alleviating the impact that the driver receives when an excessive load is applied to the parking brake;
This is an extremely practical idea as a safety device for parking brakes.
