Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD The present invention relates to a locking device for a grab door provided, for example, on the passenger side of a dashboard of a vehicle, and particularly to a locking device with a key.

"Prior Art and its Problems" Conventionally, many structures of this type of glove door lock device have been proposed and put into practical use.

There are also many high-grade devices with keys installed, but conventional devices with a whiff mechanism are generally used.

The structure was complicated, had many parts, and was expensive.

``Objective of the Invention'' The object of the invention is to provide a glove door locking device that has a built-in keyed idle mechanism, yet has a simple structure and a small number of parts and movable members.

``Summary of the Invention'' What has not yet been invented is a ratchet that grasps and releases the striker on the fixed side, a spring that biases this ratchet νI in the direction of opening the striker, and a spring that urges the ratchet νI to release the striker against this spring means. Move the lock bar from the striker gripping position to the release position.
With an opening/closing lever to help.

Gerabutaro installed in the housing on the Gerabut 7 side.
In this device, a key device is provided in the housing to rotate the key rotor roughly by + and -, and the key rotor of this key device is placed at an eccentric position.

Supporting one end of the lock part 1, as the key rotor rotates, the opening 7 part moves to the non-interlocking position with the opening/closing lever L.
It is characterized by being configured to move to the cutting position. That is, the device of the present invention is a keyed glove door opening device that incorporates a simple mechanism for moving the lock bar to a position not interlocking with the opening/closing lever by interlocking the lock bar with the key rotor.

``Embodiments of the Invention'' Figure F, 1 (uninvented embodiment) will be explained below. Figure 7 is an external view of a grab door 11 equipped with an uninvented glove door locking device, and shows an opening/closing lever 12 that is swing-operated. And +
- The mounting ff113 is exposed.

As shown in FIGS. 1 to 6, a housing 14 is fixed to the inner surface of the glove door 11, and the opening/closing lever 12 is pivotally connected to the housing 14 for opening/closing @15. This opening/closing lever 12 has a locking lever 22 suppressing protrusion 17 on its upper inner surface, and its 1mm wheel axle 1
This pressing protrusion 1 is pressed by a toe/yong spring 16 with 5 turns.
7 is urged to rotate in a direction away from the lock lever 22.

The L key device 13 includes a key cylinder portion 18 formed at -m of the housing 14, a key rotor 19 rotatably fitted in the key cylinder portion 18, and a known tumbler ( (not shown), etc. As is well known, the key rotor 19 can be rotated only when a key (not shown) is inserted into its key insertion groove 20. A vehicle movement protrusion 21 is provided at an eccentric position on the protrusion from the key cylinder part 18 on the rear surface of the key rotor 19, and this interlocking protrusion 21 is fitted into a long hole 23 formed at one end of the lock part 22. waiting. Therefore, the lock bar 22 is swingable around the rhythm protrusion 21, and moves in the longitudinal direction when the key rotor 19 is rotated. The other end of the lock part 22 constitutes a lock release part 24 that can be opened/closed and engaged with the suppression protrusion 17 of <-12, and this long release part 24 is
When the key rotor [9 is rotated to the unlock position]
As shown by the solid line in FIG. 6, it moves to an interlocking position where it can engage with the pressing protrusion 17 of the opening/closing lever 12. On the other hand, when the key rotor 19 is rotated to the key opening position, the long release portion 24 moves to a non-engaging position with the suppressing protrusion 17, as shown by the line 'icJ' in the figure. This lock, <-
22 is.

The leg portion 16a of the torsion spring 16 hung on the lower side of the torsion spring 16
As a result, the interlocking protrusion 21 is urged to rotate counterclockwise in FIG.

The housing 14 includes an upper portion of the lock bar 22,
A ratchet 30 is pivotally mounted on a shaft 29 between the pressing projection 17 of the opening/closing lever 12 and the key device 13. This ratchet 30 advances and retreats into a ratchet entry groove 31 provided integrally with the housing 14. This ratchet 30 has a striker 33 (
It has a gripping groove 34 for gripping the striker 33 (o<4) in FIG. It is biased to rotate in the direction of opening. When engaged with the lock bar 22, the lock surface 35 grips the striker 33 within the grip groove 34 against the biasing force of the torsion spring 36, thereby holding the glove door 11 in the closed position.

In this apparatus of structure L, the striker 33 has now entered the grip groove 34 of the ratchet 30, and the lock bar 22 is engaged with the lock surface 35 in the closed state 78 of the glove door 11.
(Figure 4) is assumed. In this state, if we further consider that the key rotor 19 of the key device 13 has been rotated to the 770. It is in a linked position. Therefore, opening/closing lever 1
2 by its handle part 12a, the push If protrusion 17 presses the lock release part 24 of the lock bar 22.
It is lowered against the force of the torsion spring 16 (i
! I! Therefore, the lock bar 22 and the long surface 35 of the ratchet 30 are disengaged, and the ratchet 30 releases the striker 33 by the force of the torsion spring 36, and the glove door 11 opens.

When the glove door 1] is closed, the striker 33 enters the gripping groove 34 of the ratchet 30 and rotates the ratchet 30 against the force of the torsion spring 36. ratchet 3
When the holder 35 rotates to the position of the lock bar 22, the 1lIi1 part 16a of the torque/spring 16
The spout 22, biased to one side, rotates up and engages the locking surface 35, and the glove door 11 is again held in the closed position.

On the other hand, when the glove door 11 is in the closed state, when the key rotor 19 of the +- device 13 is rotated to the key opening and release position, the opening and release part 24 of the long par 22 opens and closes, and the pressing protrusion of <-12 17 and is in a non-interlocking position. Therefore, in this state, the locking surface 35 of the long par 22 and the ratchet 30 will open and close even if < -1 and 2 are operated.
It cannot be disengaged from the connection. That is, since the opening/closing lever 12 only rotates around the housing 14 in an idle state, the glove door 11 does not open.

The relationship between the long release part 24 of the opening/closing lever 22 and the pressing protrusion 17 of the opening/closing lever 12 is such that the pressing protrusion 17 cannot suppress the lock releasing part 24 when the key lever 19 is rotated to the key lock position. Bye. Therefore, for example, as shown in FIG. 8, in the middle of the lock bar 22,
It is also possible to form the four missing parts 28 adjacent to the long release part 24, so that the pressing protrusion 17 enters into the missing part 28 when the key rotor 19 rotates to the key lock position. ``When the key is locked, the lock bar 22 moves to the non-cracking position of the opening/closing lever 12'' includes this kind of relationship.

Furthermore, in the embodiment described above, one torsion spring 16 biases the opening/closing lever 12 and the lock bar 22 to move by 1 [
This has the advantage of reducing the number of springs by one, but it is also possible to use separate springs to bias the two.

"5?! The effect of light!" As described above, the movable members of the gelabutto arotor device of the present invention are only the ratchet h, the opening/clever lever and the opening/closing lever that control the opening and closing of this ratchet, and the key rotor. , mouth 7 cleverness is linked to the rotation of the sheep-rotor,
Since it moves to the interlocking position with the opening/closing lever and the non-flooding position, it is possible to provide a glove door zero link device with a built-in missing swing mechanism, which is extremely simple and has a small number of parts. Therefore, it is possible to increase r, 7 and reduce costs.
