Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a parking brake operating device for a vehicle, which allows the operating lever to fall down from an operating position to a non-operating position while maintaining the parking brake in an operating state.

[0002]

[Prior Art]

 As a conventional device of this type, for example, as disclosed in Japanese Patent Laid-Open No. 61-218460, when a slider attached to the base of an operating lever is slid forward, a set member integrated with the slider becomes For some intermediate levers that disengage from the engaging step of the intermediate lever and maintain the brake operating state, only the operating lever can be laid down forward alone.

According to such a device, the operation lever can be laid down while the brake is operating, so that the vehicle interior space is not obstructed.

[0004]

[Problems to be solved by the device]

 In the conventional device described above, when the operator wants to lay down the operating lever while the brake is operating, he / she must grasp the operating lever's grip part with one hand and move the other slider forward. Is required and the operability is poor.

It should be noted that the operating lever cannot be laid down by moving the slider forward while pushing it down with only one hand, but since the slider is provided at the base of the operating lever, Such one-handed operation is extremely difficult.

Further, in the above-mentioned device, when the slider is moved back and forth, the set member and the engaging step portion of the intermediate lever rub against each other, and when the operation lever is rotated in the brake operating state, the slider is rotated. If the other hand is not held, the tip of the setting member slides on the arc-shaped guide portion of the intermediate lever, and their wear causes poor durability.

One that can be operated with one hand is, for example, the one disclosed in Japanese Utility Model Laid-Open No. 1-120464, but this one holds the operating lever and the intermediate lever simply by holding a spring. Since the operation lever is only elastically engaged by force, the stability of the operation lever is poor.If the operation lever is laid down just by touching it lightly, and if the spring holding force is increased, the operation lever will not rotate. There are other problems such as heavy dynamic operation.

In view of the above-mentioned problems of the prior art, the present invention can be easily operated with one hand and eliminates a sliding contact portion when the operation lever is rotated while the brake is operating, It is an object of the present invention to provide a parking brake operating device that prevents deterioration of durability due to wear or the like.

[0009]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a common lever, which is capable of rotating an operating lever and an intermediate lever connecting a cable for brake operation independently of each other into an operating position and a non-operating position. An operating device for a parking brake, which is pivotally attached to a base plate with the intermediate lever located at an operating position where the cable is pulled, and which is capable of moving the operating lever between an operating position and an inoperative position. In the above, the operating lever has an engaging portion capable of connecting the operating lever and the intermediate lever by engaging with a locking portion provided on the intermediate lever, and an operating portion protruding from the upper surface of the operating lever. The switching lever can be rotated between a locked position where the engaging part engages with the locking part and an unlock position where the engaging part disengages from the locking part and is separated from the intermediate lever by an appropriate distance. As the center And, and the operating lever, is characterized in that the switching lever is provided with retaining means you oppression held in the respective position.

[0010]

[Action]

 When the operating lever and the intermediate lever are both in the operating position and the parking brake is operated and the switching lever is turned to the unlocked position, the engaging part of the switching lever is the engaging part of the intermediate lever. When the operating lever is tilted down in this state, the engaging portion rotates together with the operating lever without slidingly contacting the intermediate lever while being held in the unlocked position by the holding means. Even when the operating lever is returned to the upright state, the engaging portion does not make sliding contact with the intermediate lever. When the switching lever is in the lock position, the engagement portion engages with the locking portion, so that the operation lever and the intermediate lever are coupled to each other.

The locking member (26) is urged clockwise by a torsion coil spring (28) wound around the shaft (27) in the respective drawings, and the hook portion (26b) always faces forward. Moreover, the stop piece (26d) is stopped at the stop position where it comes into contact with the stopper (3g) projecting inwardly at the rear edge of the bearing portion (3f) of the intermediate lever (3).

A switching lever (29) having a substantially fan shape is pivotally mounted with a shaft (30) between both side pieces (4a) of the operation lever (4) in front of the locking member (26) in the state of FIG. There is. When the operation lever (4) and the intermediate lever (3) are in the coupled position, the operation lever (4) and the intermediate lever (3) are joined to the hook portion (27b) of the locking member (27) at the rear portion of the switching lever (29). An engagement pin (engagement portion) (31) capable of connecting (4) and the intermediate lever (3) is projected.

On the upper part of the switching lever (29), there is formed an operation part (29a) projecting upward through a window hole (32) formed in the upper surface of the operation lever (4). By operating (29a), the switching lever (29) can engage the engaging pin (31) with the hook portion (26b) of the locking means (26) as shown in FIG. As shown in FIG. 2, the locking position is such that the engaging pin (31) is disengaged from the hook portion (26) and the operating portion (29a) is in contact with the front edge of the window hole (32). It can be rotated into and out of position.

Numeral (33) is a click spring (holding means) consisting of a torsion coil spring, one end of which is tried on the operation lever (4) and the other end of which is tried on the switching lever (29), and the switching is performed. When the terminal on the lever (29) side passes through the straight line (L) connecting the fastening point of the terminal on the operation lever (4) side and the shaft (30), the biasing direction is reversed and the switching lever (29 ) Can be stably held at the lock position and the unlock position.

At the front corner of the switching lever (29), when the switching lever (29) is located at the unlocked position, the rear edge of the protruding piece (23b) extending upward and forward of the release lever (23). There is formed a block portion (29b) that abuts against the push button (18) and prevents the push button (18) from being pressed.

Next, the operation of this embodiment will be described. As shown in FIG. 1, when the operation lever (4) and the intermediate lever (3) are both in the inoperative position and the switching lever (29) is in the lock position, the engagement pin (31 ) Is joined to the hook portion (26b) of the locking member (26), and the operating lever (4) and the intermediate lever (3) are connected to each other.

From this state, when the operation lever (4) is rotated in the upright direction, the engagement pin (17) pushes the intermediate lever (3), and the intermediate lever (3) also moves in the same direction. The cable (12) is pulled by this, the brake is operated, and the pawl (9) pivotally attached to the intermediate lever (3) is moved along the ratchet teeth (6). Step by step one tooth.

When the operating piece (3c) is separated from the parking brake switch (15) by the rotation of the intermediate lever (3) at this time, the switch (15) is closed and the parking break lamp of the instrument panel is turned on. ..

As shown in FIG. 2, when the operating lever (4) is stopped in the upright operating position, the pawl (9) meshes with the ratchet teeth (6) currently engaged, and the intermediate lever (3). ) Is prevented from returning to its original position, and the cable (12) is held in the pulled state.

Until this time, when the push button (18) is not operated at all, the push button (18) is kept in the projecting state by the biasing force of the compression coil spring (20) and the release lever (23). Is in a normal position.

During operation of the brake, the operating lever (4) may be kept in this standing state, but if it protrudes above the seat cushion and becomes an obstacle, Can be laid down to the inoperative position.

To this end, first, the switching lever (29) is rotated from the lock position shown in FIG. 4 to the unlock position shown in FIG. Then, as shown in FIG. 6, the engagement pin (31) is disengaged upward from the hook portion (26b) of the locking member (26).

Thereafter, as shown in FIG. 5, when the operating lever (4) is tilted forward, the switching lever (29) is held in the unlocked position by the click spring (33) and separated from the intermediate lever (3). Therefore, the switching lever (29) does not slide on the intermediate lever (3) when the operation lever (4) is rotated, and the operation lever (4) can be freely rotated with a light force.

While the switching lever (29) is held in the unlocked position, the block portion (29b) faces the rear edge of the protruding piece (23b) of the release lever (23), and the push button ( Since the pushing operation of 18) is blocked, the push button (18) is accidentally pushed during the fall of the operating lever (4) to release the brake operation state or the brake operation is actually released. However, by pushing the push button (18), it is possible to eliminate the risk of erroneous operation such as misunderstanding that it has been released. That is, since the push button (18) cannot be pushed in even if it is pushed, it can be recognized that the operating lever (4) is laid down in the brake operating state.

As shown in FIG. 3, the operation lever (4) is laid down while the brake is operating, so that the operation lever (4) can effectively use the interior space of the vehicle without hindering driving or the like. can do.

When it is desired to release the brake operation from this state, the operation lever (4) is once rotated upward to the original standing state. Then, in the reverse operation of the above, that is, as shown in FIG. 6, the engaging pin (31) slides on the guide surface (26c) of the locking member (26), so that the switching lever (29) clicks. It is rotated clockwise to the lock position shown in FIG. 4 against the biasing force of the ring (33), and as shown in FIG. 4, the engagement pin (31) causes the hook portion of the locking member (26) to move. The operation lever (4) and the intermediate lever (3) are joined to each other by joining to (26b).

When the switching lever (29) is returned to the locked position, the block portion (29b) of the switching lever (29) is disengaged upward from the rotation locus of the protruding piece (23b) of the release lever (23). ) Can be pushed in.

Next, when the push button (18) is pushed in, the release lever (23) is rotated to the release position, and the tip of the arm (23a) pushes the claw (9) to move the claw (9). Disengage from ratchet teeth (6).

From this state, when the operation lever (4) is rotated to the inoperative position shown in FIG. 1 while the push button (18) is being pushed in, the intermediate lever (3) causes the engagement pin (17) to move. And the arm (23a) of the release lever (23) so that it can be rotated together with the operating lever (4), the cable (12) is loosened, and the brake operation is released. ..

Further, when the intermediate lever (3) is returned and rotated at this time, the operating piece (3e) abuts the parking brake switch (15), and the contact is opened to turn off the parking brake lamp. To do.

Therefore, by confirming that the parking brake lamp is off, it is possible to accurately know that the brake is in the inoperative state. Thereafter, when the push button (18) is released, the pawl (9) engages with the front end portion of the ratchet tooth (6) and returns to the state shown in FIG.

7 to 14 show a second embodiment of the present invention. In the second embodiment, the same components as those in the first embodiment are designated by the same reference numerals in the drawings, and detailed description thereof will be omitted.

In the second embodiment, a fan-shaped switching lever (40) is pivotally attached to the operation lever (4) with a shaft (41), and a window hole (32) is formed in the operation lever (4). By operating the operating portion (40a) protruding further upward, the switching lever (40) is moved to the locked position shown in FIGS. 7 and 10 and the unlocked position shown in FIGS. 8, 9 and 12. It is designed so that it can rotate. When the switching lever (40) is in the unlocked position, the front corner of the switching lever (40) comes into contact with the projection (23b) of the release lever (23) and pushes the push button (18). It forms a block part (40c) that prevents only operation.

Reference numeral (42) is a torsion coil spring for constantly urging the switching lever (40) toward the lock position. A long hole (43) facing the radial direction of the shaft (41) is formed at the tip of the arm (40b) extending in an arc shape from the rear end of the switching lever (40). A pin (44) facing the left-right direction is fitted in 43).

The pin (44) is also fitted in a dogleg-shaped bent hole (45) formed in both side pieces (4a) of the operation lever (4). The bending hole (45) is formed by connecting an engaging hole (45b) facing the publication to the upper end of a vertically elongated hole (45a) that is oriented almost vertically.
