Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a locking device for a glove box lid.

Generally, a cylinder lock that rotates between an unlocked position and a locked position when operated by a key is fitted into a holder that is fixed to the lid that opens and closes the glove box of a car, etc., and the cylinder lock is turned in the unlocked position. A locking device is well known in which a lid can be opened by turning a knob to disengage a latch that engages a striker on the vehicle body.

Therefore, in conventional locking devices with cylinder locks, locking and unlocking operations using the key and opening operations using the knob are as follows.
In any case, since there is a restriction on the direction of rotation, there are difficulties in operability, such as confirmation of the direction of rotation operation and redoing the operation due to an erroneous operation.

Additionally, there was an economic disadvantage in that in order to ensure equal operability, it could not be used for both left-hand drive and right-hand drive vehicles.

The present invention has been made in view of the above-mentioned conventional problems.
A cam cylinder is interposed between the cylinder lock and the latch, which is separated when the key is inserted and engaged when the key is removed.
In addition to dedicating the locking/unlocking operation of the key and the opening operation of the knob, the locking piece of the cylinder lock can be rotated to the left and right in the holder within the latch release range around the unlocked position of the cylinder lock. By forming a wide-angle groove, the key can be used to lock and unlock the door, and the knob can be used to open the lid by turning the door on either the left or right, thereby improving operability and improving economy through dual-purpose use. be.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, glove box 1
is equipped with a lid 3 hinged to the front of a box part 2 buried in the vehicle body side so as to be openable and closable, and a holder 6 of a locking device 5 is fitted into a holder storage part 4 of the lid 3. A nut 8 is tightened into a bolt part 7 provided on the bottom surface of the holder 6 from the back side of the holder storage part 4 to fix it.

The locking device 5b is provided with a bottomed cylindrical holder 6, and a coil spring 1 is normally placed in the bottom side recess 6a of the holder 6.
0, the latch 11 is biased in the projecting direction, and in the projecting position, the latch 11 engages with the striker 12 provided on the box part 2 to close and hold the lid 3, and in the retracted position, the latch 11 is energized in the projecting direction. Then, the lid 3 can be opened.

The latch 11 is provided with an abutment piece 15 that is abutted against the cam protrusion 14 formed at one end of the cam section 13 that is rotatably fitted into the holder 6, and the latch 11 is provided with an abutment piece 15 that is abutted against the urging force. The amount of protrusion is regulated, and both left and right rotations of the cam section 13 are linked so that the cam protrusion 14 pushes it down to the retracted position.

The cam cylinder 13 is connected to the latch 110 by the piece 15.
A latch 11 in which a cam protrusion 14 faces a contact piece 15 in parallel.
The position in the rotation direction is regulated so that it is oriented at the protruding position.

On the other hand, the cylinder lock 16 is constructed by fitting a lock body 18 to which a large-diameter knob 17 is integrally attached to the holder 6, and fitting the tip of the lock body 18 to the curved end of the cam section 13 to form the holder 6. It is held in a non-removable and rotatable manner by a fastener 20 that fits into the cut groove 19 from the outside.

A coil spring 21 is attached to the lock body 18 of the cylinder lock 16.
．． . . , a plurality of locking pieces 22 . . . , with 22 in the center and protruding into a groove 28 (to be described later) of the cam cylinder 13, the cylinder 5 lock 16 and the cam cylinder 13 are connected to each other.
A locking piece 23 for connection is provided on the tip side to integrally connect the locking pieces 22, . It has a well-known configuration in which the key 25 is slid in the retracting direction.

On the inner circumferential surface of the holder 6, there is a locking piece 22 that protrudes when the key 25 is removed in the unlocked position A of the lock body 18 shown in FIG. 3a. ..., a wide-angle groove 26 for receiving 22 is provided, and the angle θ of the wide-angle groove 26 is set at the unlocked position A.
The locking piece 2 moves along with the lock body 18 in the left and right direction within the range of detachment of the latch 11 due to the left and right rotation of the cam cylinder 13.
2. ..., 22 is the rotatable range.

, Also, the holder 6 is displaced 180 degrees from the unlocked position A.
The locking position B of the lock body 18 shown in FIG.
, the locking piece 22 that protrudes when the key 25 is removed. ..., a narrow angle groove 27 is provided for receiving 22,
The lock body 18 is locked at the locking position B so that it cannot be rotated freely.

Next, as shown in FIG. 4, the connecting locking piece 23 of the lock body 18 that fits into the curved end of the cam joint 13 is placed in the locking/unlocking position A, B. A locking piece 2 for connection is provided on the inner circumferential surface of the cam joint 13, which projects when the key 25 is removed.
The lock body 18 and the cam cylinder 13 are integrally connected when the key 25 is removed.

In this manner, when the key 25 is removed, the lock body 18 is rotated by the rotation operation of the knob 17, and the cam section 13 is rotated via the locking piece 23 (for connection), so that the latch 11 can be operated to protrude and retract. When the key 25 is inserted, the connecting locking piece 23 is recessed, so the cam joint 13 is not rotated by the rotation operation of the key 25, and only the lock body 18 is rotated to lock/unlock the lock. You will be able to perform one operation.

The lock main body 18 has protrusions 18a, . . . on its distal end surface.

Fit and support the U-shaped moderation spring 29 at 18a so that the moderation spring 29 falls into the narrow angle groove 28. Make them listen.

When the locking device 5 is configured as described above, the knob 1 is placed in the unlocked position A of the lock body 18 with the key 25 removed.
7 to either the left or right, the lock body 18 is rotated, and the locking piece 22.7 is rotated in the protruding position. . . , 22 rotates within the wide-angle groove 26, and the cam joint 13 is rotated via the connecting locking piece 23 in the protruding position, and the latch 11 is pushed down to the retracted position by the cam protrusion 14. Detach from the striker 12.

In this way, the lid 3 can be opened.

When the knob 17 is released, the latch 11 is projected by the coil spring 10, and the cam joint 13 and the knob 17 are rotated to the unlocked position where the key can be removed.

Then, as the lid 3 is closed, the slope of the catch 11 engages with the slope of the striker 12, and the latch 11 engages the slope of the coil spring 10.
After being pushed down against the force, the coil spring 10 engages the striker 12 and the lid 3 is held closed.

Next, when inserting the key 25 into the key hole 24 of the knob 17,
Locking piece 22. ..., 22 and the connecting locking piece 23 are retracted, and in particular, the connection between the lock body 18 and the cam cylinder 13 is released.

Then, if you turn the key 25 to the left or right, □
Only the lock body 18 is rotated without the cam barrel 13 being rotated, and when the moderation spring 29 is rotated 180 degrees until it feels like it falls into the narrow angle groove 28 and the key 25 is removed, the locking latch piece is removed. 22. . . , 22 and the connecting locking piece 23 protrude and fit into the included angle grooves 27 and 28, respectively, so that the lock body 18 is locked in the locked position so as not to rotate freely.

In this state, even if the knob 17 is rotated, the lock body 18 cannot be rotated, so the latch 11 is not detached from the striker 12.

As is clear from the above description, the present invention includes:

A cam cylinder that interlocks with the insertion and removal of the key is interposed between the cylinder lock and the latch, and the locking/unlocking operation of the key and the opening operation of the knob are dedicated. Since it has a wide-angle groove that allows the locking piece of the cylinder lock to be rotated in the left and right directions, locking/unlocking with the key and opening the lid with the knob can be done by turning the cylinder lock in either the left or right direction. This eliminates the need to confirm the direction of operation or redo operations due to erroneous operations, improving operability.

In addition, equal operability can be ensured even when used for both left-hand drive vehicles and right-hand drive vehicles, and the spring that biases the latch in the protruding direction allows the knob to be moved through the latch and cam cylinder. Since the key can be returned to the unlocked position where it can be removed,
It has great economical effects such as no need to provide a separate spring.

Furthermore, by providing moderation in the locked and unlocked positions, the locking piece can be secured to the holder groove in the locked position,
The engagement of the connecting locking piece with the cam groove in both positions is ensured, which in turn makes it easier to insert and remove the key, and it also makes it easier to confirm the locked/unlocked position during operation, so the operation feeling is improved. You will start to improve.
