DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a glow block device applied to a glove box at a front portion of a passenger seat of an automobile.

[0002]

2. Description of the Related Art Conventionally, a glove box door that opens and closes a glove box is kept closed by engaging a striker provided on the glove box with a latch provided on the glove box door. Thereby, the engagement between the latch and the striker is released,
The glove box door is opened by its own weight. When the cylinder lock provided on the glove box door is rotated in the locking direction, the latch is fixed, and the push knob cannot be pushed, so that the glove box door is locked.

[0003]

However, in the glow block device, the push knob cannot be pushed in the locked state. Therefore, if the push knob is pushed by mistake, an excessive load is applied and internal components and the like are applied. Could be destroyed.

Accordingly, an object of the present invention is to provide a glow block device capable of pushing a push knob even in a locked state.

[0005]

In order to achieve the above object, the present invention provides a latch engaged with a striker, a claw lever engaged with the latch and holding the striker and the latch in an engaged state, and a cylinder. A slider that slides in response to the rotation of the lock, a lock lever that is rotatably attached to the slider and that engages with the claw lever to release the engagement between the claw lever and the latch; A knob for rotating the lock lever by contacting the contact portion of the lever, wherein the contact portion of the lock lever can be brought into contact with the knob in accordance with the movement of the slider, and in a position where the contact is impossible. It is intended to move.

[0006]

According to the present invention, by rotating the cylinder lock in the locking direction, the contact portion of the lock lever is moved to a position where it cannot contact the knob through the slider, and the knob swings. Is locked. On the other hand, when the cylinder lock is rotated in the unlocking direction, the contact portion of the lock lever moves to a position where it can contact the knob via the slider, and the unlock state is established.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the glow block device according to the present invention will be described with reference to the accompanying drawings. FIG.
The glove box door 1 is provided with a case including a cover 1a and a base 1b, and a glow block device is accommodated in the case. A push knob 2 and a cylinder lock 3 are provided on the base 1b, and the latch 6 is rotated via a lock lever 4 and a claw lever 5 by operating the push knob 2. When the cylinder lock 3 is operated, the slider 7 slides and the lock lever 4 rotates.

As shown in FIG. 3, the push knob 2 has a cylindrical shape with a bottom, and has a tubular pressing portion 10 having a square cross section at the center of the bottom surface. And this pressing part 1
The glove box door 1 is urged in a protruding direction by a spring 11 arranged around 0 so as to be flush with the cover 1 a provided on the glove box door 1.

The cylinder lock 3 is, as shown in FIG.
It comprises a holder 30 and a rotor 31 which rotates inside the holder 30 by inserting a key. A eccentric projection 32 is provided on the rear end face of the rotor 31.

The lock lever 4 has a cylindrical portion 17 rotatably mounted on a support shaft 36 of the slider 7 described below.
A connecting portion 18 extending from the cylindrical portion 17 and an arm portion 16 extending further perpendicularly to the connecting portion 18.
And a shaft 15 provided at the tip of the leg 16. A spring 19 is wound around the cylindrical portion 17, one end of which is fixed to the slider 7, and the other end is pressed against the arm 16 to urge the lock lever 4 counterclockwise in FIG. And the shaft 15 is connected to the base 1b.
Abuts on the stepped portion 1c. As shown in FIG. 4, the shaft 15 has a base portion pressed by the pressing portion 10 of the push knob 2, and a tip end thereof is in contact with one end of the claw lever 5 described below. .

As shown in FIG. 2, the claw lever 5 has a substantially rectangular shape, and is provided between a support plate 8a and a cover plate 8b projecting from the base 1b around a support shaft 20 provided at a bent portion. It is rotatably mounted. One end of the claw lever 5 is in contact with the shaft 15 of the lock lever 4, and the other end is provided with an engagement protrusion 21 and a locking portion 22 to which a spring 23 is locked. ing.

As shown in FIG. 2, the latch 6 is rotatably mounted between the support plate 8a and the cover plate 8b about a support shaft 25. The latch 6 is provided with a U-shaped groove 26, which engages with a striker 9a provided in a glove box (not shown) to maintain the door 1 in a closed state. An engagement receiving portion 27 with which the engaging projection 21 of the claw lever 5 is engaged and a locking portion 28 with which the other end of the spring 23 is locked are formed on the outer edge of the latch 6. .

As shown in FIGS. 3 and 4, the slider 7 is a substantially rectangular plate and is provided on the base 1b so as to slide in parallel with the cover 1a. An elongated hole 35 is provided on one side of the slider 7 in a direction perpendicular to the sliding direction, and the projection 32 of the rotor 31 is slidably engaged with the slider 7. A lever 4 is rotatably mounted.

In the glow block device having the above configuration, when the glove box door 1 is closed and in the unlocked state, the slider 7 is moved by the projection 32 of the cylinder lock 3 as shown in FIG. As shown in FIG. 5, the lock lever 4 is located on the rightmost side, and the lock lever 4 is positioned such that the shaft 15 can be brought into contact with the pressing portion 10 of the push knob 2.

When the push knob 2 is pushed in the unlocked state, the lock lever 4 is pressed by the pressing portion 1 of the push knob 2.
0, and presses one end of the claw lever 5 while rotating clockwise about the support shaft 36 (FIG. 3).
As a result, the claw lever 5 rotates clockwise about the support shaft 20, and the engagement protrusion 21 is disengaged from the engagement receiving portion 27 of the latch 6. Rotates clockwise around the support shaft 25 (FIG. 2). As a result, the holding state of the striker 9a by the U-shaped groove 26 of the latch 6 is released, and the glove box door 1 is opened by its own weight. When the push knob 2 is released, the push knob 2 returns to its original position (FIG. 2) by the spring 11 and the lock lever 4 returns to the original position by the spring 19.

Conversely, when the glow block door 1 is closed, the striker 9a rotates the latch 6 counterclockwise while abutting against the edge of the U-shaped groove 26 of the latch 6, and the spring 23 As a result of the biasing force rotating the claw lever 5 counterclockwise, the latch 6
The engaging protrusion 21 of the claw lever 5 is engaged with the engaging receiving portion 27, and returns to the closed state.

Next, the case where the key is inserted into the keyhole of the cylinder lock 3 and rotated to lock the glow block door 1 will be described. First, when the key is inserted into the cylinder lock 3 and the rotor 31 is rotated, the protrusion 32 provided on the end face thereof is rotated together with the rotor 31. Thereby, the slider 7 moves to the left in FIG. 3 together with the lock lever 4, and is positioned in the state shown in FIG. As a result, even if the shaft portion 15 of the lock lever 4 pushes the push knob 2, it retracts to a position where the push portion 10 does not come into contact, and the locked state of the latch 6 by the claw lever 5 is maintained. That is, in this state, even if the push knob 2 is pushed in, the pushing portion 10 does not come into contact with the shaft portion 15 of the lock lever 4 and swings.

[0018]

As is apparent from the above description, according to the glow block device of the present invention, when the cylinder lock is rotated in the locking direction, the contact portion of the lock lever moves to a position where the knob cannot contact. Therefore, unlike the related art, the knob itself does not become incapable of being pushed, and there is no fear that the knob is broken by an unreasonable operation.
