Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a parking device used for a two-wheeled motor vehicle, a three-wheeled buggy, a four-wheeled buggy, or the like.

(Prior Art and its Problems) Conventional parking devices include, for example, a special parking brake, its operating lever, etc., in addition to a foot brake pedal. Therefore, the cost is high and it takes time and effort to manufacture.

(Purpose of the invention) The purposes of the invention are (1) to have a simple structure and low cost, (2) to be able to be installed on conventional two-wheeled motor vehicles, three-wheeled or four-wheeled buggy vehicles, and (3) to have a brake
To provide a parking device that can be kept in the ON state, (4) has a stable locked state, and is compact.

(Means for Achieving the Object) In order to achieve the above object, the present invention provides a rack on the upper surface of the arm portion of the brake pedal, rotatably supports the shaft portion of the brake lock pawl on the step, and the shaft portion A control lever is provided at the top of the lever, and when the brake is turned on, the lock claw protrudes into the movement range of the brake pedal arm and engages the rack, pressing the arm from above. Then, the position can be freely changed to an unlocked position where the brake pedal is out of the movement range of the brake pedal and allows rotation of the brake pedal to the brake OFF position, and a spring urges the lock pawl to the unlocked position.

(Example) Fig. 1 is a plan view of a parking device applied to a two-wheeled motor vehicle (or three-wheeled or four-wheeled buggy). A pedal 1 is disposed, and the brake pedal 1 integrally includes an arm portion 2 extending in the front-rear direction and a rear end boss portion 3.
The boss portion 3 is rotatably supported by a horizontal brake support shaft 5, and the brake support shaft 5 is, for example, a right side frame 7.
is fixed to. A brake rod 9 is pivotally connected to the boss portion 3 via a bracket arm 8, and the rear end of the rod 9 is operatively connected to, for example, a rear wheel brake device.

A pair of upper and lower step brackets 10 are fixed to a portion of the frame 7 in front of the brake support shaft 5 with a plurality of bolts 11.
A step 12 extending to the right above a midway portion of the arm portion 2 is welded to the step 12. Step 12
A rack 13 is provided on the upper surface of the arm portion 2 between the brake pedal 1 and the footplate 1a of the brake pedal 1.

The brake pedal 1 is biased in the direction of arrow H in FIG. 2 by, for example, a spring means of a rear wheel brake device, and is locked (supported) at the brake OFF position shown in FIG. 2 by an appropriate stopper.

In FIG. 2, a plurality of teeth 13a are arranged on the rack 13 in the front-rear direction, and each tooth 13a is arranged in the front-rear direction.
In case a, the rear slope is formed at a generally vertical angle, and the front slope is formed at a gentle angle.

A support plate 15 is welded to the front of the upper step bracket 10 so as to project forward, and a vertical guide boss 16 is welded to the front end of the support plate 15. guide boss 16
A vertical lock pawl shaft 18 is rotatably supported inside, and a horizontal lock pawl 17 is provided at the lower end of the shaft 18.
is formed integrally with the shaft portion 18, and an operating lever 19 is connected to the upper end of the shaft portion 18 via a joint portion 20 so as to be freely rotatable as one unit. The operating lever 19 extends upward and is bent approximately horizontally at a position slightly higher than the upper end of the clutch case 14. Operation lever 19 and step bracket 10
As shown in FIG.
1 and 22 are provided, and both locking portions 21 and 22 are provided.
A return spring 23 is tensioned between them, and the elastic force of the return spring urges the lock pawl 17 and lever 19 in the direction of arrow A, and the lock claw 17 and lever 19 are engaged in the unlocked position (the position shown in Figure 1) by an appropriate stop mechanism. It has stopped.

By rotating the operating lever 19, the lock pawl 17 can be changed between the unlocked position shown in FIG. 1 and the locked position where it intersects the arm portion 2 at a substantially right angle as shown in FIG. It's becoming like that.

FIG. 5 is an exploded perspective view of the lock pawl 17, etc.
O-rings 25 are arranged at both upper and lower ends of the guide boss 16, and a ring-shaped cap 26 is arranged between the upper O-ring 25 and the joint part 20. Furthermore, a serration is formed at the upper end of the lock pawl shaft portion 18.

(Function) When parking the vehicle, press the brake pedal 1 to turn on the brake as shown in Fig. 4, turn the operating lever 19 in the direction of arrow B against the spring 23 as shown in Fig. 3, Rack the locking claw 17 1
3. By the engagement of the lock pawl 17 and the rack 13, the brake pedal 1 is locked in the brake ON position (the position shown in FIG. 4), and the rack 13 also prevents the lock pawl 17 from rotating in the direction of the reverse arrow B due to the spring 23. Ru. Note that when rotating the operating lever 19, the lever 19 is
It passes above 4.

To release the brake lock from the parked state, it is sufficient to depress the brake pedal 1 a little from the state shown in FIG. As a result, the engagement between the lock pawl 17 and the rack 13 is disengaged, and the elastic force of the return spring 23 causes the lock pawl 17 to automatically return to the unlocked position shown in FIG.

Generally, the play stroke of the brake pedal increases due to wear of the brake, but in such a case, the tooth portion 13a that engages with the lock pawl 17
(Fig. 2), the rear tooth portion 13a (second
By using the (Fig.), you can increase the amount of depression when locking and lock with the brakes working reliably.

(Another Embodiment) (1) In the embodiment shown in FIG. 6, the rack 13 has an arcuate shape along the circumference centered on the rotation center O of the lock pawl 17. According to the device shown in FIG. 6, the lock pawl 17 and the rack 13 intersect at right angles when viewed from above no matter which tooth portion 13a is engaged, so that the lock pawl 17 and the rack 13 can be engaged more reliably. Become.

(2) In the embodiment shown in FIG. 7, the upper end of the rack 13 is formed to be higher toward the rear. With the configuration shown in FIG. 7, the amount of depression of the brake during parking can be further increased compared to the configuration shown in FIG. 2.

(Effects of the invention) As explained above, the invention provides a rack on the upper surface of the arm of the brake pedal, rotatably supports the shaft of the brake lock pawl on the step, and attaches the operating lever to the top of the shaft. When the brake pedal is turned on, the lock pawl projects into the movement range of the brake pedal arm and engages with the rack, pressing the arm from above to the lock position and movement of the brake pedal. The position can be changed freely to the lock release position that allows the brake pedal to rotate to the brake OFF position when the brake pedal is out of the range.
Since the lock pawl is biased to the unlocked position by a spring, there are the following advantages.

(1) Since the parking device is attached to small members such as the step and the arm of the brake pedal, it can be installed in the body of a conventional two-wheeled motor vehicle without directly modifying the vehicle body itself.

(2) A lock pawl is provided on the step near the brake pedal, and the brake pedal arm is directly locked without using wires, etc., so the structure is simple and the brake pedal is reliably locked. You will be able to do things.

(3) Since the lock pawl is urged to the unlocked position by the spring, the lock can be automatically released by simply depressing the brake pedal further from the locked state. That is, the unlocking operation is easy.

(4) The rack 13 is formed directly on the upper part of the arm part 2 of the brake pedal 1, and the lock pawl 17 is attached to the arm part 2 of the brake pedal 1 when in the lock position.
Since it protrudes into the movement range of the arm 2 and directly presses the arm 2 from above, the locking state is stable, the rack (sector) installation work, etc. is not required, and the compactness can be maintained. can.
