Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to an emergency release device for a trunk lid lock of an automobile, which allows the trunk lid lock mechanism to be unlocked from inside the trunk compartment.

To lock the trunk lid of a car, push the key into the key cylinder attached to the trunk lid from the outside and turn the key in the unlocking direction (usually clockwise) to lock the trunk lid locking mechanism. Alternatively, as disclosed in Japanese Utility Model Application No. 54-92513, the trunk lid lock mechanism can be unlocked and opened by operating the opener handle installed inside the vehicle. Ru.

However, since the above-mentioned conventional device is configured to unlock the trunk lid lock mechanism by operating from outside the trunk, for example, if a child accidentally locks himself in the trunk, The problem is that the trunk lid lock mechanism cannot be unlocked from the inside, making it impossible to escape on your own, leading to a serious accident.

This invention was created in view of the above-mentioned conventional problems, and is an automobile trunk lid that can prevent the above-mentioned accidents by being configured so that the trunk lid lock mechanism can be unlocked even from inside the trunk compartment. The purpose of this invention is to provide an emergency release device for a drop lock.

Embodiments of this invention will be described below with reference to the drawings.

In FIGS. 1 and 2, 1 is a trunk lid, and 2 is a reinforcement, and this reinforcement 2 is attached to the inside of the trunk lid 1 with a space 3 present therein.

The trunk lid 1 is locked by a trunk lid locking mechanism 4, and the trunk lid 1 is locked by a trunk lid locking mechanism 4.
By closing the door and releasing the lock of the lock mechanism 4, the trunk lid 1 moves in the direction of arrow A and opens the trunk room 5.

The trunk lid lock mechanism 4 includes a key cylinder 6 attached to the trunk lid 1 and a third key cylinder.
As is clear from the figure, an actuating plate 7 is attached to the tip of the key cylinder 6, and a claw lever 10 and a pin are pivotally supported via pins 9 to a retaining plate 8 fixed to the reinforcement 2. 1
A lock lever 13 consisting of a fork lever 12 pivotally supported via a lock lever 1;
The striker 14 corresponds to the fork lever 12 at 3.

The lock lever 10 and the fork lever 12, which constitute the lock lever 13, are connected to each other by hooking a spring 15 to one end of each. An extension piece 10a close to the side end surface 7a is formed, and a spring 15 is formed.
A convex portion 10b that protrudes toward the fork lever 12 is provided at an intermediate position between the hook portion and the pin 9.

The fork lever 12 has a recess 12a formed at its other end to engage and disengage the striker 14, and an extending piece 1 extending from the pin 11 in the direction of the fork lever 10.
2b is provided with a notch 12c into which the convex portion 10b of the black lever 10 engages and disengages.

Therefore, in the locked state shown in FIG. 3, when releasing the lock from the outside, push a key (not shown) into the key cylinder 6 and rotate the key to move the actuating plate 7 to the third position. Rotate in the direction of arrow B in the figure. When the operating plate 7 rotates, its side end surface 7a presses the extending piece 10a of the black lever 10 in the rotating direction (direction of arrow B).
0 rotates in the direction of arrow C about the pin 9 as a fulcrum, and reaches the state shown by the imaginary line X, where the convex portion 10b is separated from the concave portion 12a of the fork lever 12, and one end side is displaced upward to tension the spring 15. .

For this purpose, one end of the fork lever 12 is pulled by the spring force of the spring 15, and the fork lever 12 becomes rotatable in the direction of the arrow D about the pin 11, and as the trunk lid 1 moves in the direction of the arrow A, the fork lever 12 moves into the recess. 12a is detached from the striker 14, and the trunk lid 1 is opened.

On the other hand, the reinforcement 2 has a notch 16
is formed, and a push plate 17 is fitted into this notch 16. The push plate 17 is attached to the reinforcement 2 so as to be movable in the direction of arrow E, that is, upward, about a support shaft 18. One end of one link 19a constituting the link member 19 is connected to the extending piece 17a extending upward on the base end side of the push plate 17, and the other end of one link 19a is connected to the other end of the link 19a. It is connected to the upper end of link 19b.

The base end 19c of the other link 19b passes through the through hole 8a formed in the holding plate 8, and the through hole 8a
When punching and forming, it is rotatably attached via a pin 20 to the bent piece 8b that is continuous and bent from one side of the through hole 8a, and is in contact with the lower surface of one end side of the black lever 10. are in contact with each other.

A return spring 21 has one end in contact with the inner surface of the trunk lid 1 and the other end in contact with the upper surface of the push plate 17, and normally applies a spring force in the direction of closing the notch 16 with the push plate 17. ing. In the figure, 22 indicates a stop lever, and 23 indicates a holder that slidably holds one link 19a.

In the above configuration, when unlocking the trunk lid lock mechanism 4 from inside the trunk, the push plate 17 is pressed in the direction of arrow E against the spring force of the return spring 21.

By the above pressing operation, the push plate 17 is
rotates about the support shaft 18 in the state shown by the imaginary line Y, and pulls one link 19a in the direction of arrow F.
Therefore, the other link 19b rotates around the pin 20 as shown by the imaginary line Z, and the black lever 10
In order to lift one end side upward, the locking mechanism 4 is unlocked and the trunk lid 1 is opened by the same operation as the above-mentioned operation from the outside.

In order to make the push plate 17 easier to see in a dark trunk when a child is locked in the trunk, the pressing surface of the push plate 17 may be coated with, for example, fluorescent paint. In order to encourage pressing of the tsushi plate 17, the word "male" may be written with fluorescent paint or the like.

In the above embodiment, the push plate 17
An extension piece 17 extending upward toward the proximal end side.
a, and one link 1 is attached to this extending piece 17a.
Although an example in which one end of the push plate 9a is connected is described, this invention is not limited to the above embodiment. For example, as shown in FIG. Even if one link 19a is connected to one end 17b of the push plate 17, the same effect as in the above embodiment can be obtained.

As explained above, according to this invention, a push plate is attached to the reinforcement installed inside the trunk lid so as to be movable upward, and the push plate and the lock lever of the trunk lid locking mechanism are connected by a link member. The lock lever is rotated to release the lock by moving the push plate upward, so even if a child becomes trapped in the trunk, they can easily escape on their own. ,
This has the advantage of preventing accidents from occurring.
