Description

[Detailed explanation of the idea] 《Industrial application field》 This invention relates to a resin locking device.

<<Summary of the invention>> A lock release piece is integrated with the tip of the lock claw, and the lock claw is unlocked by placing a finger on a pull ring provided at the tip of the lock release piece and pulling it.

<<Prior Art>> For example, in a luggage space or a trunk room, as shown in FIG. 3, a recess formed by a floor panel 1 is covered with a floor trim 2, which is a cover body, and a recess 1a for a spare tire is covered. The front end of the floor trim 2 is rotatable about a thin hinge portion 2a, and the rear end is locked by a resin lock 3 to avoid rattling due to vibrations of the vehicle body.

As shown in FIG. 4, the resin lock 3 conventionally includes a panel portion 3a fixed to the floor trim 2 and a lock claw portion swingably supported by a lower protruding end 3b of the panel portion 3a via a thin hinge portion 3c. 3d, and a lock release knob 3e inserted into the hollow interior of the panel portion 3a and integrated into the upper part of the lock claw portion 3d.
As shown in Fig. 3, the lock claw part 3
The floor trim 2 is fixed onto the floor panel 1 by engaging the locking portion 1b formed at the rear of the opening edge of the recess 1a formed by the floor panel 1.

<<Problem to be solved by the invention>> When attempting to release the lock of the lock claw part 3d by pressing the knob 3d, insert your finger into the narrow gap between the locking part 1b of the floor panel 1 and the knob 3e, and press the knob 3d. 3e, making it difficult to operate, and since there is a limit to how much finger pressure can be applied, the work becomes extremely difficult when the lock is hard.

《Means for solving the problem》 The purpose of this invention is to be able to lock the lid with a large force by pulling it. A resin lock is provided on the lid body and locks the lid body in a closed state, and the locking device has a mounting plate attached to the lid body and swings through a thin hinge part on the lower surface of the mounting plate. A lock claw that is protrusively provided and engages with a locking portion formed on the opening edge of the recess, a lock release piece that is integrated with the tip of the lock claw and extends to the upper surface of the mounting plate, and the lock release The present invention provides a resin locking device comprising a pulling ring integrally formed at the tip of the piece, and configured so that the engagement between the lock pawl and the locking portion is released by pulling the pulling ring.

<<Embodiment of the invention>> Hereinafter, an embodiment of the invention will be described in detail using the drawings.

FIG. 1 is a perspective view showing a resin locking device according to this invention.

In the figure, the locking device 10 includes a mounting plate 12 and a thin hinge portion 1 on the lower surface of the plate 12.
4, a lock pawl 16 is swingably protruded through the lock pawl 16.
and a stop wall 18 protruding parallel to the lock pawl 16.
and a spring piece 20 formed protruding from the back of the locking pawl 16, and the plate 12 integrated with the tip of the locking pawl 16 and in contact with the tip of the stopper wall 18.
A lock release piece 22 extends to the upper surface of the plate 12 through a notch 12a formed on one side, and a pull ring 2 integrally formed at the upper end of the lock release piece 22.
It consists of 4.

The spring piece 20 abuts against the stop wall 18, and as a result, the lock pawl 16 is moved from the hinge portion 14 to the stop wall 1.
It is biased in the direction away from 8.

When the resin locking device 10 having the above structure is attached to the tip of the floor trim 2, which is a lid that covers the recess 1a and rotates about the thin hinge 2a, the floor panel 1 will be closed as shown in FIG. The lock pawl 16 comes into contact with a locking portion 1b formed at the opening edge of the recessed portion 1a to lock the floor trim 2 in the closed state.

To release the lock, wrap your finger around the pull ring 24 and pull it in the direction opposite to the rear wall of the vehicle body panel. The lock pawl 16 will be latched off from the locking portion 1b against the elasticity of the spring piece 20, and the lock pawl will be released. 16 and the locking part 1b
This results in the disengagement of the two.

In the above embodiment, the locking force is increased by the spring piece 20, but it is also possible to provide the lock pawl 16 itself with a biasing force in the locking direction without using the spring piece 20. .

<Effects of the invention> As explained in the examples above, this invention has the following effects:
Since the lock is released by pulling the lock pawl in the opposite direction to the locking direction, it is possible to apply a larger force than the conventional method of releasing the lock by pushing with a finger.

Further, even if there is a barrier on the lock side, the user does not have to insert his or her finger into a narrow gap, so the lock release operation can be easily performed.
