As a result, the bracket that supports the open lever and the lift lever is formed in a flat plate shape, which requires a small volume. As a result, the storage space in the door occupied by the door locking device is reduced.

(Embodiment) An embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 to 3, in the door lock main body 1 disposed on the door side, a latch that can engage with a striker disposed on the vehicle body side and a pole that restricts rotation of the latch are provided. A door closing mechanism (not shown) is provided.

A bracket 2 is fixed on the door lock main body 1. A lift lever 3 for operating a pole of a door closing mechanism is rotatably supported by a pin 4 on the bracket 2.

A locking lever 5 is slidably and rotatably supported on the bracket 2 via a link 6. The locking lever 5 is adapted to engage with the lift lever 3 by a sliding operation, and is rotated by a rotating operation.
The engaging portion of is disengaged from the sliding locus of the locking lever 5. A spring 15 is arranged between the link 6 and the bracket 2, and the spring 15
The locking lever 5 is always urged by the urging force so that the locking lever 5 slides in the direction opposite to the separating direction, that is, the direction engaging with the lift lever 3. The locking lever 5 is connected to a locking link 7 which is rotatably supported by the bracket 2 and is connected to an output shaft 14 of a drive mechanism (not shown) arranged in the door lock body 1. There is. A locking lever 19 connected to a key cylinder (not shown) provided outside the door 9 shown in FIG. 4 via a link 18 is rotatably supported around the output shaft 14. The locking lever 19 is engageable with the locking link 7. Further, the locking lever 5 is connected via an open link 8 to an outside handle (not shown) provided outside the door 9.

The bracket 2 has a bell crank-shaped open lever
10 is rotatably supported by a pin 11. An inside handle 20 shown in FIG. 4 arranged on the indoor side of the door 9 is connected to one end of the open lever 10 via a connecting link (not shown). An open link 12 slidably supported by the bracket 2 is connected to the other end of the open lever 10 by a pin 13, and the open link 12 is arranged in parallel with the lift lever 3 and engages with the lift lever 3. It is about to do. This open link
The sliding of 12 is guided by the engagement of the long hole 16 formed in the open link 12 and the upright portion 17 formed in the bracket 2.

 Next, the operation will be described.

FIGS. 1 to 3 show the unlocked state, and when the outside handle is operated in this state, the locking lever 5 is spring-loaded via the open link 8.
The claw portion 5a formed on the locking lever 5 moves downward in the second drawing against the urging force of 15 and engages with the claw portion 3a formed on the lift lever 3 (refer to the locking lever 5 described above). Engagement of the lift lever 3). As a result, the lift lever 3
Rotates around the pin 4 in the second counterclockwise direction in the drawing to release the closing mechanism (release operation of the engagement between the pole and the latch), and when the door 9 is closed, the opening operation standby state (the pole When the latch is disengaged and the door 9 is opened, the ratch can be separated from the striker. Further, when the locking link 7 is rotated by the operation of the key cylinder or the drive mechanism, the locking lever 5 rotates about the pin 21 in the clockwise direction in the second drawing. As a result, the claw portion 5a of the locking lever 5 is disengaged to a position where it cannot engage with the claw portion 3a of the lift lever 3 (from the sliding locus of the locking lever 5 at the engaging portion of the lift lever 3 described above). Of departure), it becomes a lock state. In this state, even if the outside handle is operated, the locking lever 5 does not engage with the lift lever 3 and swings freely, so that the closing mechanism does not release.

When the inside handle 20 is operated in the unlocked state, the open lever 10 rotates about the pin 11 in the counterclockwise direction in the third drawing. By this rotation of the open lever 10, the open link 12 moves upward in the second drawing, and the claw portion 12a formed on the open link 12 engages with the wall portion 3b formed on the lift lever 3 (the open link described above). 12
With the lift lever 3). As a result, the lift lever 3 rotates about the pin 4 in the second counterclockwise direction, and the closing mechanism is released. When the inside handle 20 is operated in the locked state shown in FIGS. 5 and 6, the open lever 10 rotates about the pin 11 in the counterclockwise direction shown in FIG. By this rotation of the open lever 10, the open link 12 moves upward in the second drawing, and the claw portion 12a formed on the open link 12 engages with the wall portion 3b formed on the lift lever 3. As a result, as shown in FIGS. 7 and 8, the lift lever 3 is moved around the pin 4 to the second position.
The closing mechanism is released by rotating counterclockwise in the drawing, and the claw portion 3c of the lift lever 3 is moved to the wall portion 5b of the locking lever 5.
The locking lever 5 is rotated about the pin 21 in the clockwise direction as shown in FIG.

In this way, the closing operation of the closing mechanism by operating the inside handle 20 is performed regardless of the locked state and the unlocked state. As a result, when the door 9 is opened from the room in the locked state, the unlocking state and the opening operation standby state can be achieved by the one motion of only the operation of the inside handle 20, and the operability can be improved. Further, the open link 12 is arranged in parallel with the lift lever 3, and the lift lever 3 is rotated by the sliding operation of the open link 12, so that the bracket 2 supporting the open link 12 and the lift lever 3 is formed into a flat plate shape. It can be done in a small volume. As a result, the storage space in the door 9 occupied by the door locking device can be reduced. Furthermore, since the open link 12 does not protrude from the door locking device and completely fits in the volume, it has high anti-theft property, and the protector for covering the open link 12 and the locking lever 5 which is added as anti-theft device is also small and simple in shape. It is possible to do so, and it is easy to manufacture. Further, since one end of the open link 12 is pivotally supported by the open lever 10 and engages with the lift lever 3 at the other end,
It is possible to achieve one-motion by only adding the open link 12, the number of parts is small, and the parts where sliding and rotation resistance is generated are small, so that it is easy to assemble and is advantageous in terms of manufacturing man-hours and cost. At the same time, it is possible to suppress deterioration of operation feeling and increase of abnormal noise. Further, since the open link 12 does not protrude from the door locking device and completely fits in the volume, the open link 12 interferes with the shape of the door 9 and the shape and arrangement of links that are connected to related operation parts such as the inside handle 20. The design flexibility and versatility can be enhanced without any restrictions on

[Effect of device]

The present invention is linked to a lift lever that unlocks a door closing mechanism by a rotating operation, and an inside handle that is disposed in parallel with the lift lever and that is engaged with the lift lever by a sliding operation. Since the door lock device is configured to have the open link, the closing operation of the closing mechanism by the inside handle can be performed regardless of the locked state and the unlocked state. Thus, when the door is opened from the room in the locked state, the unlocking state and the opening waiting state can be achieved by the one-motion operation of only the inside handle, and the operability can be improved.

Further, since the open link is arranged in parallel with the lift lever and the lift lever is rotated by the sliding operation of the open link, the open link does not protrude from the door locking device and is completely contained within the volume. As a result, the bracket supporting the open link and the lift lever can be formed in a flat plate shape, and a small volume is sufficient. For this reason, the storage space in the door occupied by the door locking device can be reduced, the door is not thickened, and the space for arranging other functional components in the door is not restricted. Further, the open link does not interfere with the shape of the door and the shape and arrangement of the links that are connected to the related operation parts such as the inside handle, and the design flexibility and versatility are high. it can. In addition, the protector for covering the open link and the locking lever, which is added to prevent theft, can be made small and have a simple shape, resulting in good manufacturability.

Also, since one end of the open link is pivotally supported by the open lever and the other end engages with the lift lever, one-motion can be achieved by only adding the open link, the number of parts is small, and sliding and rotation are possible. Since there are few resistance generating parts, it is easy to assemble, which is advantageous in terms of manufacturing man-hours and costs, and it is possible to suppress deterioration of operation feeling and increase of abnormal noise.
