Description

DETAILED DESCRIPTION OF THE INVENTION (Field of application of industrial balls) The present invention relates to a bonnet locking device for an automatic vehicle.

(Prior art) A conventional bonnet lock device is attached to a tunic,
A stopper that engages with the striker installed on the bonnet side. 4--
and a claw bar that engages with the fork and holds the fork and the striker in a 4" position.The claw lever of this Honnesotrosota device is installed in the driver's seat. It is connected to the claw release lever by a wire. Then, when the lock release lever is operated from the driver's seat and the claw lever is rotated, the engagement between the fork and the slider is released, and the fork is released. It is designed so that it can be used to strike the net through the striker.

In addition, with the structure in which the front end of the bonnet/hood opens, if the fork disengages from the slider/leica while driving, the bonnet/hood may open and obstruct visibility. A safety lock is provided to prevent the Leica from separating from the bonnet lock device. In these cars, you operate the lock release lever from the driver's seat to release the lock, and then lift the hood while operating the safety hook.

(Problems to be Solved by the Invention) However, in the conventional Bonnesotlock device,
When operating the lock release lever, the bonnet hood did not move as far as it should, so there was a small gap between the tip of the bonnet hood and the heavy object, making it difficult to lift it with your fingers.

In addition, especially in the case where the safety hook is set to LT, the safety hook is operated by inserting your finger into the gap between the end of the main net hood and the car body, but this is difficult to operate because the gap is small. There was a problem.

Therefore, in order to increase the lift-up jet of this Bonnesoto hood, it is possible to increase the stroke of the hook or to separately install a lift-up device using a spring, etc., but in each of the previous cases, The net lock device becomes larger, and the latter requires additional installation space for the lift-up device, and has the disadvantage that assembly is difficult.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a compact bonnet locking device with a large amount of lift assembling of a bonnet hood.

(Means for Solving the Problem) In order to achieve the above-mentioned object, the present invention provides a fork that engages with a striker provided on the bonnet side, and a fork that engages with the fork and engages with the fork.・In a bonnet locking device equipped with a claw lever that maintains an engagement-like deafness with the Leica, a lift bar having a rotation stroke of the hook A-L [J-K-L rotation stroke] The G is rotatable based on the G and is biased in the direction of pushing up the striker.

(Function) When the fork and the striker are engaged and the bonnet/hood is closed, when the claw lever is rotated by the lock release operation, the engagement between the fork and the striker is completely released, and the fork is closed. climbs up to the urging force and rotates to push the striker 111:L. , 11+1 Bonnesotoff-1.

(Example) Next, an example of the present invention will be described with reference to the accompanying drawings.

FIG. 1 shows a bonnet locking device according to the present invention, in which a substantially box-shaped base 1 fixed to a vehicle body (not shown) has a striker 2 fixed to the tip of a bonnet hood (not shown) fitted at its top end. Slit 3 is colored.

A fork 4, a claw lever 5, a safety lever 6, and a lift lever 7 are attached to the base 1.

The fork 1 is rotatably attached to a support shaft 8 provided on the base l. And this fork 4 has
As shown in FIG. 3, a U-shaped notch 9 that engages with the striker 2 and intersects with the slit 3, and a recess 10 in which a claw 16 of a claw lever 5, which will be described later, is engaged;
A coil spring accommodating hole 12 having an arcuate cutout for accommodating the coil spring 11 is formed. Coil spring storage room
A collar spring retainer 13 for retaining one end of the foil spring l1 is formed at the end of the foil spring l1.

[The lever 5 is rotatably attached to a support shaft 1 provided on the base. A wire +5 is connected between the tip of this lever 5 and an unillustrated release lever on the driver's seat side. Also, in the middle of this hook lever 5, there is a hook 4 according to III.
A nail groove 16 which is attached to the concave portion {0} is formed.

The safety support 6 has a substantially rectangular shape with a handle 17 at one end and a flap 18 at the other end, and is rotatably attached to a support 19 provided on the base l in the middle thereof. The safety flap 6 is biased clockwise in FIG. 1, and comes into contact with a stopper (not shown) to stop the safety flap 18 closing the entrance of the slit 3 of the moeki base 1.

Lift lever 7
It is mounted coaxially with and rotatable independently of the fixture 1.

As shown in FIG. 3, this lift lever 7 includes a protruding piece 20 and a first folding piece 2 with the tip of the protruding piece 20 bent.
1 and a second stake piece 22 formed by bending the side part of the protruding piece 20, a coil spring retainer 23 is formed. The coil spring holding portion 23 fits into the coil spring accommodating portion I2 of the fork 4 to hold the other end of the coil spring I1.

The lift lever 7 and the claw lever 5 are connected by a fill spring 21, and the lift lever 7 is biased counterclockwise in FIG. 1, and the claw lever 5 is biased clockwise. Note that a torsion spring may be used instead of the coil spring 24. 1 Base I
The striker 2 can be suppressed by intersecting with the slit 3. Then, the lift lever 7 pushes the striker 2 from the locked state shown in FIG. The lever length of the lift lever 7 is determined so that the lever length of the lift lever 7 is longer than the rotation stroke of the lever 4 until the lever 1 pushes the striker 2 to the full extent.

In the bonnet lock device having the following configuration,
In the case of a deaf person with the phonenet closed,
As shown in FIG.
When the claw lG of 5 is engaged, the notch 9 engages with the striker 2 and is held at a position intersecting the slit 3. In addition, the rift 1 lever 7 (j) is biased counterclockwise in FIG.
It's H.

From this locked state, when the lock release lever (not shown) on the driver's seat is operated and the wire 15 is pulled in the /li direction in FIG.
It moves counterclockwise against the urging force of.

As a result, Tsumero l6 of claw lever 5 moves to peak 4.
The rift 1 lever 7 rotates counterclockwise around the support 8 due to the biasing force of the coil spring 24, and presses the Sui Leica 2 upward by 1+11 so that it is attached to the honnet foot (not shown). Press 42. And striker 2
is pressed by riff 1 and lever 7 and moves in two directions,
Press the edge of the notch 9 of the fork 4. Therefore, as the striker 2 moves in the direction in which it separates from the thread 3, the fork 4 is moved around the spindle 8 while almost maintaining the positional relationship shown in FIG. 1 with the lift lever 7. It rotates counterclockwise in the figure. At this time, the coil spring 11 moves to the hook 4 and the lift lever 7 with almost no expansion or contraction.

Then, the hook 4 rotates by that rotation stroke,
When the notch 9 of the fork 4 and the striker 2 are disengaged, the lift lever 7 further rotates beyond the rotation stroke of the fork 4, so the striker 2 is lifted as shown in FIG. It is further pressed by the lever 7 and moves upward. As a result, the bonnet hood will be pushed further up. At this time, the coil spring l1 is compressed by the amount that the lift lever 7 rotates relative to the fork 4. As a result, the fork 1 is biased counterclockwise in FIG. 2, and the entrance of the slit 3 is kept open.

The bonnet hood is lifted up by the lift lever 7, and the gap with the vehicle body becomes Δ, so the safety lever 6 is equipped with a 6-gun in the operating position 17 (6 is easy to lift and is easy to hold and operate). Become.

Insert your hand 1 into the gap between the lifted bonnet hood and the turret, and push the operation part 17 of the safety hook 6 into the second position.
When pulled up toward the center of the figure, the safety lock 6 rotates counterclockwise in the figure, and the safety lock 18 moves to the left in the figure, opening the slit 3. As a result, the striker 2 is able to separate from the striker 3, so if you lift the tip of the striker 2 and the hood of the body, the hood will open. And safety hook 6
When the hand is released from the operating portion 17, the safety hook 6 is rotated clockwise in FIG. 2 by the {1 force, and the hook 18 returns to the state in which the slit 3 is closed.

When the tip of the bonnet hood is pushed up to close the bonnet, the striker 2 shown by the two-dot chain line in FIG. 2 collides with the slanted tip of the hook l8 of the safety book 6,
The safety fitting 6 is used as a biasing force to rotate it counterclockwise in the figure, and it is fitted into the opened slit 3. Then, the striker 2 further collides with the lift lever 7 and moves the lift lever 7 into the second position against the biasing force of the coil spring 24.
Turn the fork clockwise in the figure, and then turn the notch 9 of the fork 4.
The fork 4 collides with the mouth of the lift lever 7 and engages with the notch 9, causing the fork 4 to rotate clockwise together with the lift lever 7.

This rotation of the hook 4 causes the claw l of the crawler 5 to
When the fork 6 slides on the end surface of the fork 4 and locks on the groove 10, the notch 9 of the fork 4 intersects with the slits 1 and 3, as shown in FIG. - The Leica 2 is trapped in the space surrounded by the notch 9 and the slit 3 and becomes a lock-like book.

In the above embodiment, the claw lever 5 and the lift lever 7 are biased by a common coil spring 24, but they may be biased independently by separate coil springs.

Further, the coil spring l1 that biases the fork 4 may be connected to the base (2). In this case, the amount of expansion and contraction of the coil spring is required to correspond to the rotational stroke of the fork 4, which is larger than that of the embodiment described above.

(Effects of the Invention) As is clear from the above 1, the present invention provides that the lift lever of the Jichirege and Honnet hoods can be lifted up by a lift lever that rotates beyond the rotational stroke of the fork. This makes opening the phone easier. In addition, since the lift lever for increasing the lift-up amount is built into the body of the device, it has the advantage of being compact.
