DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an automobile hood locking device.

(Prior art) A conventional bonnet lock device is attached to the vehicle body,
It includes a fork that engages with a striker provided on the bonnet side, and a glow lever that engages with the fork to maintain the engaged state between the fork and the striker. The glow lever of this bonnet lock device is connected by wire to a lock release lever provided on the driver's seat. When the glow lever is rotated by operating the lock release lever from the driver's seat side, the engagement between the fork and the striker is released, and the fork pushes up the bonnet hood via the striker.

In addition, for those with a structure where the front end of the bonnet hood opens,
In order to prevent the bonnet hood from opening and obstructing visibility if the fork and striker disengage unexpectedly while driving, a safety footer is provided to prevent the striker from separating from the bonnet locking device. ing. With this model, you operate the lock release lever from the driver's seat to release the lock, and then lift the bonnet hood while operating the safety hook.

(Problems to be Solved by the Invention) However, in the conventional bonnet lock device,
Because the amount of lift of the bonnet hood when operating the lock release lever was small, the gap between the tip of the bonnet hood and the vehicle body was small, making it difficult to lift the hood with one's fingers.

In addition, especially in vehicles having the safety hook, the safety hook is operated by inserting a finger into the gap between the tip of the bonnet hood and the vehicle body, but since the gap is small, there is a problem in that it is difficult to operate.

Therefore, in order to increase the amount of lift-up of the bonnet hood, it is possible to increase the stroke of the fork or install a separate lift-up device using a spring, etc., but the former would result in a larger bonnet lock device, and the latter However, there is a drawback that an extra mounting space is required for the lift-up device and that assembly is complicated.

The present invention has been made in view of such problems, and an object of the present invention is to provide a compact bonnet lock device that can lift up a bonnet hood by a large amount.

(Means for Solving the Problems) In order to achieve the above 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 to maintain a state of engagement between the fork and the striker. In a bonnet lock device, a mount base fixedly provided on the vehicle body includes a slide base that is slidable in the opening/closing direction of the bonnet, and a spring member that biases the slide base toward the striker. The fork and the glow lever are attached to the slide base, and a locking member is provided that can be engaged with and detached from the mount base in conjunction with the glow lever.

(Operation) When the fork and the striker are engaged, the engagement member of the slide base is engaged with the mount base, and the bonnet hood is closed, when the glow lever is rotated by the lock release operation, the fork and the striker are engaged. is released, the fork presses the striker by its rotation,
Push up the bonnet hood.

At the same time, the locking member separates from the mount base in conjunction with the rotation of the glow lever. As a result, the slide base slides toward the striker by the biasing force of the spring member, presses the striker, and pushes up the bonnet hood.

Leave from 5.

As a result, as shown in FIG.
The striker 12 is rotated counterclockwise by its biasing force around l, pushing the striker 12 upward and pushing up a bonnet hood (not shown). In addition, the lift spring 4 pushes up the slide base 2 by its urging force, and the striker l2
Push the hood up through the bonnet.

Therefore, the bonnet hood is lifted up significantly by an amount equal to the weight of the lift-up amount by the fork 14 and the lift-up amount by the slide base 2, the gap between the bonnet hood and the vehicle body becomes larger, and the bonnet becomes easier to lift.

Additionally, as the slide base 2 slides upward,
The operating lever 28 of the safety hook 16 approaches the gap between the bonnet hood and the vehicle body, making it easier to operate from the gap.

Insert your hand through the gap between the lifted-up bonnet hood and the vehicle body, and press the operation part 28 of the safety hook 16 into the fourth position.
When pulled upward in the figure, the safety hook l6 rotates counterclockwise in the figure, and the hook 29 moves to the left in the figure, opening the slit 13.13a. As a result, the striker 12 can be removed from the slit 13.13a, so that by lifting the tip of the bonnet hood that is integrated with the striker 12, the bonnet opens. Then, when you release your hand from the operation part 28 of the safety hook 16,
The safety hook l6 rotates clockwise in FIG.

When the tip of the bonnet hood is pushed down to close the bonnet, the striker 12 shown by the two-dot chain line in Figure 4 is a safety hook! The safety hook l6 collides with the inclined end of the hook 29 of No. 6, rotates the safety hook l6 counterclockwise in the figure against the biasing force, and fits into the opened slits 13, 13a. Then, the striker 12 further collides with the mouth of the notch 22 of the fork 14 and engages with the notch 22, causing the fork 14 to rotate clockwise in FIG. 4 against the biasing force. It fits into the slits 13 and 13a.

Due to this collision of the striker 12 with the hook 29 and the fork 14, the slide base 2 slides downward while bending the lift spring 4 as shown in FIG. At this time, the pressure contact l1 at the lower end of the slide base 2 collides with the stop rubber 3 via the lift spring l4.
Conflicts are reduced.

Due to the rotation of fork l4, glow lever l5 moves to Tsumuro 2.
6 is a fork! When the end surface of the fork l4 is slid onto the end face and locked in the recess 23, as shown in FIG.
intersects the slits 13 and 13a, so the striker 1
2 is confined in the space surrounded by the notch 22 and the slits 13, 13a, and is in a locked state. At the same time, the sliders 17 and 17 slide away from each other via the crank plate l8 and the connecting lever 19 due to the rotation caused by the claw lever 26 of the claw lever 15 being locked in the recess 23 of the fork l4. By moving, the claws 31, 31 fit into and lock into the locking holes 5.5 of the mount base l. As a result, the slide base 2 is restrained from vertically sliding relative to the mount base l, and is completely locked.

In the above embodiment, the locking members that can be connected to and detached from the mount base in conjunction with the glow lever slide in a direction perpendicular to the sliding direction of the slide base 2, and their tips are locked to the mount base l. However, the present invention is not limited to this, and for example, the glow lever l5 is used.
It may also be a lever-shaped member that rotates in conjunction with the mount base I and has a hook at the tip that engages with the bottom wall of the mount base I.

(Effects of the Invention) As is clear from the above description, according to the present invention, the bonnet hood has a lift-up amount due to the rotation of the hood and a lift-up amount due to the slide of the slide base. The amount of lift is increased, making it easier to open the bonnet. Also, a slide base. Since the mechanism for increasing the amount of lift consisting of a locking member and a spring member is integrated into the bonnet locking device, it has the effect of being compact.
