Description

[Detailed Description of the Invention] The disclosed technology belongs to the technical field of preventing the boot from getting caught in the safety cover of a center lever type parking brake lever provided in the driver's seat of an automobile.

In this invention, a pole supported by a pin on the parking brake lever body, which is pivotally supported by a sector fixedly erected along the longitudinal direction on the left and right sides of the driver's seat, engages and disengages with the ratchet of the sector. The present invention relates to a parking brake lever structure in which the main body penetrates through a boot of a safety cover that surrounds the sector, and in particular, the parking brake lever structure is linked to a release button at the tip of the handle. The side part of the parking brake lever main body that corresponds to the above-mentioned ratchet engaging part of the parking brake lever main body that moves is bulged so as to be sufficiently covered in the lateral direction, thereby preventing interference with the engaging part of the pawl of the boot and the ratchet. This invention relates to a parking brake lever structure in which a check hole for inspection of the engaging portion is bored in the bulging portion.

As is well known, parking brake devices are one of the safety devices of automobiles, and there are various types of them.For example, parking brake devices are installed at the front stage of the center tunnel due to various advantages such as being able to maintain a stable driving position. Lever type ones are widely used.

As shown in FIG. 1, this type of lever type parking brake device 1 has a sector 4 having a ratchet 3 on the floor 2, which is provided along the longitudinal direction by bolts 5, 5, and is connected to the shaft 6 of the sector 4. A parking brake lever main body 7 is pivotally supported to be able to rotate, and a pawl 11 connected to a release button 9 at the tip of the handle 8 via a rod 10 is pivotally supported by a pin 12 of the parking brake lever main body 7 to move the above-mentioned sector. The parking brake lever main body 7 can be engaged with and disengaged from the ratchet 3 of the sector 4, and the parking brake lever main body 7 can be inserted into a boot 13 as a safety cover surrounding the sector 4.

In the conventional parking brake lever device 1, the pawl 11 of the parking brake lever main body 7 and the engaging portion 14 of the ratchet 3 are hollowed out into a concave portion 15 so that they can be checked from the side. It is formed.

Therefore, when the parking brake lever main body 7 is repeatedly rotated, the engaging portion 1 of the boot 13
The folded portion 13' of the corresponding portion of No. 4 tends to interfere with the engaging portion 14, and when vertical and lateral vibrations are also applied, the bent portion 13' of the corresponding portion 4 tends to become jammed and cut.

Therefore, when a break occurs, the broken part spreads due to repeated use, and there is also the problem that dust can enter.

The purpose of this invention was to solve the problem of the parking brake safety cover getting caught in the boot based on the prior art described above, by making the side part of the parking brake lever body bulge out to cover the engaging part of the pawl and ratchet. It is an object of the present invention to provide an excellent parking brake lever structure which eliminates interference with the engaging part of the brake lever and also allows the engaging part to be inspected through a check hole in the bulged part.

The structure of this invention in accordance with the above-mentioned purpose is that when the handle is pulled, the parking brake lever main body is pivoted on the shaft and rotates around the sector, the pawl is latched, the brake cable is pulled, and the braking action is performed. To release the brake, press the button on the handle to disengage the pawl and ratchet, rotate the parking brake lever in the opposite direction around the sector, and return it. During this time, the engaging part of the pawl and ratchet will release the parking brake from the side. It is laterally covered by the bulge-shaped portion of the lever body, and therefore,
The boot of the safety cover is blocked by the bulge and does not come close to the engaging part of the pole and ratchet, so there is no chance of getting caught or cut, and inspection of the engaging part requires drilling into the bulging part. The gist of this is that the check can be easily performed using the provided check hole.

Next, one embodiment of this invention will be described below based on FIG. Note that the same parts as in FIG. 1 will be explained using the same reference numerals.

Reference numeral 1' denotes a parking brake device which constitutes the gist of this invention, in which a sector 4 with a ratchet 3 engraved on the floor 2 of the driver's seat is fixed and erected via bolts 5, 5, and a parking brake is attached to the shaft 6 of the sector 4. A brake lever body 7' is rotatably supported, and a pawl 11 is linked to a rod 10 connected to a release button 9 at the tip of the handle 8 and is freely supported on a pin 12 of the parking brake lever 7'.
The ratchet 3 can be engaged with and disengaged from the ratchet 3.

13 is a boot of the safety cover, through which the parking brake lever 7' is inserted at the base of the handle 8.

The basic structure described above is substantially the same as the conventional embodiment shown in FIG. A bulging portion 15' is formed to cover this when viewed from the side.
Further, as shown in the figure, a circular check hole 16 is drilled in the bulging portion 15' for checking the engagement between the ratchet 3 and the pawl 11, so that the entire stroke can be checked by rotating the parking brake lever 7. has been done.

17 is a brake cable whose base is connected to an adjustment screw 18.

In the above structure, when operating the parking brake, if the parking brake lever main body 7' is turned clockwise in the figure via the handle 8 and raised, the pawl 11 moves freely to the ratchet 3 and the brake cable 17 is pulled. Predetermined braking is performed.

To release the brake, the release button 9 is pressed as in the conventional case, the pawl 11 is disengaged from the ratchet 3 via the rod 10, and the parking brake lever 7' is pushed down to release the brake.

During this time, the engagement and separation operations of the pawl 11 with respect to the ratchet 3 are caused by the bulging portion 15' when viewed from the side.
Therefore, although the front lower part 13' of the boot 13 may come into contact with the vicinity of the edge of the bulging portion 15', it does not interfere closely with the engaging portion 14.
Therefore, it will never get caught between the pole 11 and the ratchet 3.

Therefore, cutting or breaking due to biting will not occur.

Further, inspection of engagement and separation of the entire stroke of the pawl 11 and the ratchet 3 during repair and inspection can be easily and reliably performed through the check hole 16.

It goes without saying that the embodiments of this invention are not limited to the above-mentioned embodiments. For example, various methods may be used, such as installing an L-shaped protector laterally on the edge of the bulge so as not to interfere with the pole. Aspects can be adopted.

As mentioned above, according to this invention, in the center lever type parking brake lever structure,
By making the side part of the parking brake lever corresponding to the pawl and ratchet engagement part bulge-shaped so that the engagement part can be covered when viewed from the side,
Even if the parking brake lever is repeatedly rotated, the boots of the safety cover will always be blocked by this even if they come into close contact with the bulge-shaped part, and will never be able to come close to the engaging part. It has an excellent effect of not getting caught in the pole and ratchet, cutting or breaking.

In addition, since the bulging portion is provided with a check hole for inspecting the engaging portion, it not only has the effect of allowing easy inspection, but also allows for easy inspection of the engaging portion.
It has an excellent effect that it can also be used as a measurement standard for the degree of wear of the pole.

Another advantage is that the bulging portion and the check hole can be molded at the same time when molding the parking brake body, and the structure is simple.
