Description

[Detailed Description of the Invention] This invention relates to a locking device for a glove box.

A cylinder lock is installed on the opening/closing lid of the glove box formed on the instrument panel of a car.
Glove boxes that can store valuables are available (for example, Japanese Patent Application Laid-Open No. 1989-1999).
Publication No. 119084). In this kind of glove box,
A cylinder lock is provided on the case attached to the opening/closing lid, and a lock member is provided that interlocks with the rotation of the cylinder lock via a slide member, etc., and a striker that engages and disengages with the lock member is provided protruding from the box body side. However, in order to tell whether the opening/closing lid is in the locked or unlocked state, it is necessary to determine the orientation of the small key insertion slot in the cylinder lock, and it is better to check this visually than manually. Since it is faster than the conventional method, it is now done manually, but it still has drawbacks such as not being able to make quick decisions and being time-consuming.

The purpose of this invention is to eliminate the above-mentioned conventional drawbacks and to make it possible to distinguish at a glance whether or not the device is in a locked state.

In order to achieve this purpose, this invention includes a case attached to the opening/closing lid of the glove box, which is provided with a cylinder lock that rotates between a locking position and an unlocking position, and a slide in which an engaging portion is formed in the case. The member is slidably housed, and this case is provided with a locking member that engages and disengages with a striker provided in the glove box, and when the cylinder lock is rotated to the lock position, the engagement portion of the slider member engages with and disengages. A locking device for a glove box is provided, characterized in that an engaging protrusion that engages and moves the slide member to the inner wall of the case is formed on a cylinder lock. As described above, the cylinder lock is provided with an engagement protrusion and a slide member formed with an engagement part that engages with the engagement protrusion, and when the cylinder lock is in the unlocked position, the slide member is moved to the center of the case. Push it into the
The movement of the slide member disengages the lock member from the striker, and when the cylinder lock is rotated to the lock position, the slide member moves from the unlocked position located approximately in the center of the case until it abuts the inner edge of the case. This makes it impossible to put a finger inside the case to open the lid, and when the lid is locked, the opening operation is disabled, and when the slide member is unlocked, it is located approximately at the center of the case. When the slide member is locked, it is displaced significantly compared to when it is unlocked, and moves to a position where it touches the inner wall of the case, so it is possible to determine at a glance whether or not it is in the locked state based on the position of the slide member.

This invention will be explained in detail below with reference to embodiments shown in the drawings.

A case 2 is attached to the center of an opening/closing lid 1 that opens and closes the front opening of a glove box (not shown). By pulling to the side,
An opening/closing lid 1 whose lower end is rotatably pivoted to the box body is opened.

The case 2 has a shape as shown in the figure, with front and rear side walls 2
a, 2b, left and right side walls 2c, 2d, a bottom wall 2e with an opening in the center, and a bottom wall 2 with a gap A between the left side wall 2c and the left side wall 2c.
A partition wall 2f protruding from the partition wall 2f, an upper wall 2g bent upward from the upper end of the partition wall 2f, and a cylinder storage portion 2h protruding from the back surface of the upper wall 2g are integrally formed. The cylinder storage portion 2h includes:
The cylinder lock 3 is mounted so that the key hole 3a is located in the mounting hole drilled in the upper wall 2g, and is opposed to the inner peripheral surface of the cylinder storage part 2h which rotatably contacts the outer periphery of the cylinder lock 3. Lock side key protrusion grooves 4, 4 and unlock side key protrusion grooves 5, 5 are carved. The lock side key protruding grooves 4, 4 are the lock plates 6...6 housed inside the cylinder lock 3.
The unlock side key projection grooves 5, 5 are larger than the lock plates 6...6, and are rotatable within the projection grooves 5, 5 by a predetermined angle. The lower end portion of the cylinder lock 3 protrudes from the cylinder storage portion 2h, and a large diameter portion 3c has an engagement protrusion made of a pinion gear 3b formed on the lower end portion on a semicircumferential surface.
is formed.

A slide member 7 is housed in the case 2 so as to be slidable between the top wall 2g and the bottom wall 2e. The slide member 7 has a shape as shown in the figure, and forms a gap B between the right side wall 7a and the case right side wall 2d, and also forms a hook operating portion 7c hanging from the lower surface of the upper wall 7b. A pair of guide parts 7d and 7e extending leftward from the lower left end of
are provided so as to move along the inner surfaces of the front and rear side walls 2a and 2b of the case 1. An engaging portion consisting of a rack gear 7f is formed on the inner surface of the one guide portion 7e, and the rack gear 7f is engaged with the pinion gear 3b of the cylinder lock 3.

Furthermore, a bottom plate 8 is attached to the bottom wall opening of the case 2, a hole 8a is bored in the bottom plate 8, and a hook 9 serving as a locking member is rotated to the bracket 11 via a shaft 10 so as to pass through the hole 8a. The hook 9 is freely supported, and the hook 9 is biased clockwise by a spring member 12. The upper part 9a of the hook 9 protruding into the case 2 is located on the right side of the cylinder lock 3, and is adapted to move toward and away from the hook operating part 7c of the slide member 7 as the slide member 7 moves. . Further, a striker 13 is provided at a position corresponding to the lower side of the hook 9 so as to protrude from the glove box. The opening/closing lid 1 is held in the closed position.

Next, the operation of the above device will be explained.

When the key hole 3a of the cylinder lock 3 is in the Y direction in the figure,
is in the unlocked position, and when in the unlocked position,
As shown in FIGS. 1 to 6, the pinion gear 3b of the cylinder lock 3 is connected to the rack gear 7 of the slide member 7.
The slide member 7 is engaged with the intermediate portion of f.
is located at a position where the right side wall 7a and the case right side wall 2d have a gap B large enough to allow a finger to be inserted. At this time, the hook operating portion 7c of the slide member 7 is in a position close to the upper side portion 9a of the hook 9, and the hook 9 is urged by the spring member 12 and engages with the striker 13.
The opening/closing lid 1 is held in the closed position.

In the unlocked position, when opening the opening/closing lid 1, insert your fingers into the gaps A and B on both the left and right sides of the case 2, and then move the slide member 7 inward in the direction of the arrow, as shown in FIG. push. At this time, the lock plates 6...6 of the cylinder lock 3 protrude into the unlocking side key protruding groove 5, but the angle α to the groove side end is
(shown in FIG. 3), and the rack gear 7f of the slide member 7 engages with the pinion gear 3b and moves to the left. When the slide member 7 moves to the left, the hook actuating part 7c pushes the upper part 9a of the hook 9 against the pressure of the spring member 12, rotates the hook 9 counterclockwise, and disengages it from the striker 13. solve. Therefore, when you pinch the partition wall 2f and the right side wall 7a of the slide member with your fingers inserted into the gaps A and B and pull them forward, the opening/closing lid 1 will open, and when you close it and release your hand, the hook 9 will open with a spring member. The striker 13 is biased and rotates.
At the same time, the slide member 7 is moved slightly to the right and returned to the unlocked position.

On the other hand, when the key is inserted into the cylinder lock 3 and the cylinder lock is rotated 90 degrees clockwise to the locked position in the X direction in the figure, the cylinder lock 3
Rack gear 7f meshes with pinion gear 3b of
moves to the right, the slide member 7 moves to the right inside the case 2, and moves to a position where the right side wall 7a approaches the right side wall 2d of the case 2. Therefore, the gap B disappears, making it impossible to insert a finger. Further, as the slide member 7 moves to the right, the hook operating portion 7c is in a position where it does not interfere with the hook 9, and the hook 9 engages with the striker 13 by the spring member 12, thereby locking the opening/closing lid 1 in the closed position. In this lock position, the lock plate 6 of the cylinder lock 3
... 6 is engaged with the lock side key protrusion groove 4, the cylinder lock 3 cannot be rotated and the slide member 7 cannot be moved to the left, and since there is no gap B, the slide member 7 cannot be moved by inserting a finger into the cylinder lock 3. I can't even push it to the left. Therefore, the opening/closing lid 1 is reliably locked.

Note that this invention is not limited to the above embodiment, and as shown in FIGS. 9 and 10, a cam 3'd is formed on the outer periphery as an engaging protrusion formed on the cylinder lock 3', while a slide member An engaging portion 7'k formed at 7' is a curved contact surface bent to the right between front and rear guide members 7'd and 7'e.
may be formed. In this embodiment, when the cylinder lock 3' is in the unlocked position, as shown in FIG.
The cam 3'd is not in a position where it is in contact with the engaging part 7'k,
The slide member 7' is free, and the engagement between the hook 9 and the striker 13 can be released by pushing the slide member 7'. When the cylinder lock 3' is placed in the lock position, the cam 3'd rotates toward the engaging portion 7'k, moves the slide member 7' to the right, releases the hook 9 and the slide member 7', and returns the cylinder lock 3' to the locked position. cam 3
Since d' stops, the slide member 7' cannot move to the left and is in a locked state.

As is clear from the above explanation, according to the glove box locking device of this invention, when the cylinder lock is placed in the locked position, the sliding member is located on the right peripheral wall of the case, so it is obvious at first glance that the glove box is in the locked state. It can be determined whether or not. Furthermore, since it is not possible to insert a finger in the locked position, the lock cannot be destroyed by forced operation, and the lock is reliably locked, which has various advantages such as sufficient prevention of theft.
