DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lock mechanism for a glove box lid (hereinafter, simply referred to as a lid).

[0002]

2. Description of the Related Art As shown in FIG. 5, when a lid a is turned, a glove box b is turned on.
The lock bar d is pressed down by coming into contact with the striker c provided in the above. When the striker c passes, the lock bar d is raised by the return spring e to lock.

[0003]

However, in the lock mechanism having the above-mentioned structure, since the upper end of the lock bar is exposed to the inside of the glove box, there is a case where the stored object hits. Further, there is a demand for downsizing the configuration of the lock mechanism and ensuring the lock operation. The present invention has been made in view of the above, and an object of the present invention is to provide a lid locking mechanism that is reliably operated and has a reduced size.

[0004]

According to the present invention, there is provided a lid locking mechanism for rotating a lid for closing a glove box by rotation and a striker provided on the glove box. To the lid
A ratchet is disposed, and a spring for biasing the rotation in a direction out of engagement with the striker mounted on the ratchet, the spring elastic force of the automatic return spring mounted on the handle for performing opening operation of the lid An actuating stopper ,
A vertical guide for the stopper formed on the body of the lock mechanism, the striker of the ratchet
The stopper engages with the spring of the automatic return spring
It moves upward due to elasticity and pivotally engages with the striker.
While holding the ratchet
When the stopper is moved downward by operation, the ratchet
Glove box that releases the holding action on
In the lock mechanism of the X-lid, the automatic return cover is provided.
Hook the end of the screw into the spring hook hole formed in the stopper
It is characterized in that spring elasticity is urged .

[0005]

According to the above construction, when the lid is rotated to close the glove box, the ratchet is rotationally engaged with the striker. At this time, the stopper is guided by the vertical guide formed on the body ,
Holding the ratchet moves upward by the spring elastic force of the automatic return spring mounted, stock by operation of the handle
The holding action on the ratchet is released by moving the par down.
Let go. Bar with the end of the spring for automatic return formed on the stopper
Since the spring elasticity is urged by hooking the hook hole, the stopper can be quickly and reliably operated.

[0006]

Embodiments of the present invention will be described with reference to the accompanying drawings. 1 is a cross-sectional view of a lid lock mechanism 1, FIG. 2 is a rear view thereof, FIG. 3 is a cross-sectional view of a body 2 taken along line AA in FIG. 2, and FIG. is there. The lock mechanism 1 is composed of a body 2 fixed to a lid 31, a ratchet 3, a handle 4, a stopper 5, a torsion spring 6 for urging the ratchet 3, and a torsion spring 7 for automatic return hung on the handle 4. I have.

On the body 2, a bracket 11 for rotatably supporting the ratchet 3, a bracket 12 for rotatably supporting the handle 4, and a vertical guide 13 for the stopper 4 are formed by integral casting. . Ratchet 3
Is the striker 33 disposed on the glove box 32 side.
An abutment piece 14 that abuts on the engagement member 15, an engagement groove 15 that is rotated by the abutment and engages with the striker 33, and a locking step 16 that is locked by the stopper 5 are formed. A ratchet 3 and a torsion spring 6 having coil portions on both sides of the ratchet 3 are rotatably supported on the support shaft 17 inserted through the shaft support bracket 11. In the torsion spring 6, the locking portion 6 a in the middle of the coil portion is stopped by the abutting piece 14 of the ratchet 3, and each end of the coil portion on both sides is locked between the shaft support brackets 11.

The handle 4 is rotatably supported on the bracket 12 by a shaft 18 together with a torsion spring 7 for automatic return. The torsion spring 7 is configured such that an intermediate locking portion 7a between the coil portions on both sides is hooked on one shaft support piece 12a of the bracket 12, and the ends of the coil portions on both sides are hooked on the handle 4 and the stopper 5, respectively. I have. The stopper 5 is
Guide grooves 13a on both sides of the vertical guide 13 of the body 2
It is fitted in. As shown in FIG. 4, the stopper 5 has a spring hooking hole 19 formed in the center, and the tip 7b of the coil portion of the torsion spring 7 is locked as described above. Therefore,
The stopper 5 is guided by the guide groove 13 a of the vertical guide 13 and rises due to the spring elasticity of the torsion spring 7, and comes into contact with the ratchet 3. The stopper 5 is formed with a pair of pressure receiving pieces 21 on both sides thereof corresponding to the pressing pieces 20 formed on the handle 4.

When the lock mechanism 1 rotates the lid 31 to close the glove box 32, the abutting piece 14 of the ratchet 3 abuts on the striker 33. Then, the ratchet 3 rotates against the spring elasticity of the torsion spring 6 and engages the striker 33 with the engagement groove 15. Ratchet 3 at the same time
Is locked by the stopper 5 which is raised by the spring elasticity of the torsion spring 7, the ratchet 3 is held in a state where the striker 33 is engaged, and the lid 31 is locked to the glove box 32.

From the locked state of the lid 31, the handle 4
1 is rotated toward the front as shown by the arrow x in FIG. 1, and the stopper 5, which presses the pressure receiving piece 21 against the pressing piece 20 of the handle 4, moves up and down against the spring elasticity of the torsion spring 7. It is guided by the guide groove 13a of the direction guide 13 and descends to release the engagement of the ratchet 3. Thereby, the torsion spring 6
The abutment piece 14 of the ratchet 3 that rotates due to the spring elasticity abuts on the striker 33, the striker 33 is detached from the engagement groove 15, and the lock mechanism 1 is unlocked. The lid 31 is pivoted downward by its own weight to rotate the glove box 3.
Open 2.

The above-described lock mechanism 1 of the present invention has the above-described structure and operation, and the ratchet 3
, The position of the striker 33 can be disposed deeper than the glove box 32. Further, since the holding and release of the ratchet 3 are performed by the stopper 5 which moves up and down, the lid 31 is securely locked.
Can be performed, and the moving distance can be shortened . Further, the tip 7b of the spring 7 for automatic return is stored.
A spring elastic hole is provided by hooking a spring hook hole 19 formed in the
Since the stopper 5 is urged, the stopper 5 can be quickly and reliably operated, and there are advantages that the space for disposing the stopper 5 provided in the body 2 can be reduced and the size can be reduced.
