Description

[Detailed description of the invention] (Field of industrial application) The present invention is a lock that engages the door with the car body and holds it in the closed state when the door, which is provided on the car body so that it can be opened and closed, is closed. It is related to the device.

(Prior Art) Vehicle doors are hinged to the vehicle body so that they can rotate freely, and are opened and closed by this rotation, and a locking device is used to hold the door in a closed state when the door is closed. is provided. As this locking device, for example, a locking mechanism that can be freely engaged and disengaged from a striker on the vehicle body is used, and when the door is closed, this locking mechanism automatically engages with the striker. In order to open the door, it is necessary to disengage the lock mechanism and the striker. For this purpose, the door is provided with an outer handle and an inner handle, and the above engagement is released by operating these handles. It's getting old.

A structure conventionally used as a locking device for such a door is shown in FIG. 6, and the conventional locking device will be explained using this figure. The door 10 has an inner panel 11 and an outer panel 1
2, and a window glass 1 that can be opened and closed vertically is arranged inside the door 10. An outer handle 2 is attached to the outer panel 12 side of the door 10 so as to be rotatable about a shaft 2a, and a recess 12a is provided below the outer handle 2 so that a hand can be inserted in order to operate the outer handle 2. It is formed. On the other hand, the lock portion 8 is provided at the rear end of the vertically central portion of the door 10, and has a hook (lock mechanism) that engages with a striker (not shown) on the vehicle body side when the door 1 is closed.
This hook is connected to the intermediate link 9, and when the intermediate link 9 is moved downward from the illustrated state, the engagement between the hook and the striker is released. The upper end of the intermediate link 9 is connected to the left end 5c of the open lever 5 via the pin 6. Open lever 5
is rotatably attached to the lock part 8 by a shaft 5a at the center, and the right end 5b is close to or in contact with an inner lever 7 connected to an inner handle (not shown) at its lower surface. Further, the pin 6 is loosely inserted into an elongated hole 4b formed at the lower end of the connecting rod 4. A screw 4a is formed at the upper end of the connecting rod 4, and is fitted and connected to the adjuster clip 3 by the screw 4a, and the adjuster clip 3 is pivotally attached to the outer handle 2 at the position shown in the figure. This adjustment clip 3 is used to adjust the vertical position of the connecting rod 4, and is used to adjust the vertical position of the connecting rod 4.
a and the adjustment clip 3 can be connected at any position in the vertical direction, and after adjusting the relative position of the connection rod 4 and pin 6 to the position shown in Fig. 6, the adjustment clip 3 can be connected at that position. 3 and a screw 4a of a connecting rod 4 are fitted and connected. The locking device is assembled by hand through an opening 11a formed in the inner panel 11. The lock device as described above is already known; for example, Japanese Utility Model Publication No. 13012/1983 discloses a structure of a lock device and adjuster clip similar to the structure shown in FIG. 6.

Next, the operation of the above locking device will be briefly explained. First, as shown in Fig. 7, when the outer handle 2 is pulled by hand and rotated in the direction of arrow _A1 ,
The connecting rod 4 is moved downward (arrow A ₂ direction), and the open lever 5 is rotated around the shaft 5a (arrow A ₃ direction).
At the same time, the intermediate link 9 is moved downward ( _{in the four} directions of arrow A). Therefore, the engagement between the hook and the striker is released and the door can be opened. In addition,
The right end 5b of the open lever 5 is the inner lever 7
Since the inner lever 7 is rotated in the direction away from the inner lever 7, the inner lever 7 is not moved. On the other hand, pull the inner handle (not shown) and turn the inner lever 7 clockwise (in the direction of arrow A ₅ ) as shown in Fig. 8.
When the right end 5b of the open lever 5 is rotated, the right end 5b of the open lever 5 is pushed upward, and the open lever 5 is rotated counterclockwise (in the direction of arrow _A6 ) about the shaft 5a.
The intermediate link 9 is moved downward (in the direction of arrow A ₇ ) via the pin 6. This releases the engagement between the hook and the striker. At this time, since the pin 6 is rotated along the long hole 4b at the lower end of the connecting rod 4, the connecting rod 4 does not move and the outer handle 2 does not move.

(Problem to be solved by the invention) In the above-mentioned locking device, it is necessary to accurately position and adjust the position of each member so that each member operates accurately and unlocks in response to the operation of the outer handle or inner handle. be. In this case, it is unavoidable that dimensional errors and installation position errors will occur in each member, so the connection position between the upper end screw 4a of the connection rod 4 and the adjuster clip 3 can be adjusted, and before this connection is made, After adjusting the position of other parts, the screw 4a and the adjuster clip 3 are connected at the adjusted position. however,
Since the door lock device is disposed within the closed section formed by the inner panel 11 and the outer panel 12, the above installation work must be performed through the opening 11a formed in the inner panel 11. Work is often difficult. In particular, when the outer handle of the door is arranged at the rear end of the door and the position of the adjuster clip 3 pivoted to the outer handle is away from the opening 11a, the adjustment of the attachment position using the adjuster clip 3 is necessary. The problem is that it becomes very difficult.

(Means for Solving the Problems) The present invention aims to improve the workability of adjusting the mounting position using such an adjuster clip. As a means for this purpose, the open lever is pivotally connected to the lock part and one end is connected to the lock mechanism, and when the open lever is rotated by the inner handle, the lock mechanism is activated and the lock mechanism and the vehicle body are engaged. The link member is pivotally connected to the pivot shaft to the lock portion of the open lever, and is connected to the open lever with a predetermined play by the elongated hole, and one end of the connecting rod is connected to the outer It is pivotally attached to the handle, and the other end of the connecting rod, such as a screw, is formed with a concave and convex portion that repeats concavities and convexities in the axial direction, and this concave and convex portion allows the other end to be fitted and connected to the adjuster clip. It is attached to the link member so as to be rotatable around an axis substantially parallel to the pivot axis of the open lever, and the predetermined play is provided in the direction in which the open lever rotates when the inner handle is operated, and when the open lever is opened by operating the inner handle. The lock device is configured such that the link member does not rotate when the lever rotates, but when the link member is rotated by operating the outer handle, the open lever also rotates together with the link member.

(Function) Since the locking device of the present invention is constructed as described above, the open lever can be rotated by operating either the inner handle or the outer handle, and the door can be opened. Moreover, the inner handle is not interlocked when the outer handle is operated. Additionally, since the adjustment clip is attached to a link member that is pivotally connected to the lock, the adjustment clip can be positioned near the opening of the inner panel even when the outer handle is attached to the rear end of the door. . In addition, since the adjuster clip is attached to the link member so that it can rotate around an axis that is approximately parallel to the pivot axis to the lock portion of the open lever, manufacturing errors and assembly errors in each part may occur during assembly. Even if a relative rotational positional shift occurs between the connecting rod and the link member due to such reasons, the positional shift can be absorbed by the rotation of the adjuster clip. There is no need to rotate the member around its elongated hole to absorb the rotational position shift, and therefore the direction of the link member and its elongated hole is preset based on the rotation locus of the open lever, etc. It is possible to avoid deviation from the orientation, thereby ensuring smooth door lock release operation. (If the direction of the link member and its elongated hole deviates from the above preset direction, when the link member rotates, the elongated hole of the link member and the open lever (for example, the elongated hole of the link member provided in the open lever) mated pin)
This may cause strain or the like to occur between the door and the door, making it impossible to smoothly release the door lock. ) Also, when the adjuster clip is rotatably attached as described above, in the process of transmitting the downward stroke of the connecting rod to the open lever, the link member is placed in two locations: the adjuster clip portion and the elongated hole portion of the link member. As a result, when the connecting rod makes a downward stroke, the link member tilts and displaces, making it impossible to accurately transmit the downward stroke of the connecting rod to the open lever via the link member. To solve this problem, in the present invention, the link member is pivotally connected to the pivot shaft of the open lever as described above, so that the movement of the link member is limited to rotation around the pivot shaft. Free tilting displacement of the member is no longer possible, which makes it possible to accurately transmit the downward stroke of the connecting rod to the open lever via the link member, making it possible to rotate the adjusting clip as described above. Even if the door is attached, the door lock can be reliably released.

(Embodiments) Hereinafter, preferred embodiments of the present invention will be described based on the drawings.

FIG. 4 shows an automobile having a door 10 equipped with a locking device according to the present invention. At the top of the door 10 there is a window glass 1 whose lower part is housed inside the door 10 and can be opened and closed by moving up and down. An outer handle 2 is attached to the rear end of the handle 10. FIG. 1 shows this door 10 viewed from the rear of the vehicle body, and the right side in the figure is the interior side of the vehicle.

The door 10 is constructed by welding an inner panel 11 and an outer panel 12, and the inner panel 11 has an opening 11a formed therein. A lock portion 8 is attached within the closed cross section formed by joining both panels 11 and 12, and this lock portion 8
An open lever 5 is pivotally connected to the opening lever 5 via a pivot shaft 5a. The lower surface of the right end 5b of the open lever 5 is in contact with or close to the inner lever 7, and the left end is connected to the intermediate link 9 via the pin 6. The intermediate link 9 is connected to a hook (lock mechanism), and when the intermediate link 9 is moved down from the illustrated state, it is disengaged from the vehicle body side striker (none of which is illustrated). The above structure is the same as that of the conventional lock device shown in FIG.

A link member 30 is rotatably attached to the pivot shaft 5a of the open lever 5, and the open lever 5 and the link member 30 are connected to each other via a pin 6 loosely inserted into an elongated hole 31 formed as shown in the figure. The elongated hole 31 and the pin 6 are connected to each other with a predetermined play. An adjuster clip 3 is pivotally attached to the link member 30, and the adjuster clip 3 is connected to the rod 20 formed at the lower part of the connecting rod 20.
It is fitted and connected to the lower screw 20b, which serves as a concavo-convex portion with repeated concave-convex portions in the axial direction. On the other hand, the upper screw 20a of the connecting rod 20 and the connector 21 are screwed together, and the connector 21 is pivotally attached to the right end 2c of the outer handle 2, which is pivotally attached to the outer panel 12 via the shaft 2a. Outer handle 2
The handle 2b projects to the outside above the recess 12a of the outer panel 12. Note that the predetermined play caused by loosely inserting the pin 6 into the elongated hole 31 is as follows when neither the outer handle nor the inner handle is operated.
As shown in FIG. 1, the pin 6 is provided in the rotation direction of the open lever 5 to which the pin 6 is attached.In this state, when the link member 30 is rotated counterclockwise around the pivot shaft 5a, the open lever 5 is opened. 5 is also rotated together, but when only the open lever 5 is rotated, the pin 6 only moves within the elongated hole 31 and the link member 30 is not moved during this time.

The locking device configured as described above is installed in the door 10 through the opening 11a, and the final position adjustment at the time of installation is performed by adjusting the connecting position between the lower screw 20b of the connecting rod 20 and the adjusting clip 3. It is done. The connection between the adjuster clip 3 and the screw 20b will be explained with reference to FIGS. 5A and 5B.

The adjusting clip 3 includes a main body portion 3b having a pivot shaft 3c projecting downward in the figure, and a main body portion 3b.
The cover part 3d is hinged to the cover part 3d. The pivot shaft 3c is inserted into a pivot hole 32 formed at the end of the link member 30, and the adjuster clip 3 is rotatably attached to the link member 30. A recess 3a having a female thread is formed on the upper surface of the main body 3b, and the recess 3a has a repeating semi-cylindrical recess and recess.
Place the lower screw 20b of 0 and attach it to the cover part 3d.
The adjusting clip 3 and the connecting rod 20 can be connected by covering and holding them as shown in FIG. 5B. In addition, at this time, the hook 3e at the tip of the cover part 3d is connected to the protrusion 3 formed at the end of the main body part 3b.
f, and the cover portion 3d engages with the main body portion 3b while holding the lower screw 20b of the connecting rod 20. By doing the above, the screw in the recess 3a and the lower screw 20b of the connecting rod 20 are connected.
By fitting the two, the two can be reliably connected, and the fitting position of the two can also be adjusted as desired.

As described above, the adjustment clip 3 makes the final adjustment of the mounting position of each member. In the present invention, the adjustment clip 3 is connected to the connecting rod 20 near the lock portion 8. Therefore, even when the outer handle 2 is disposed at the end of the door, the adjuster clip 3 is attached to the opening 11a of the inner panel 11.
It can be placed near the lock device, making the installation work of the lock device easy.

The operation of the locking device constructed as above will be explained. First, the operation when operating the outer handle 2 will be explained based on FIG. 2. When the handle 2b of the outer handle 2 is pulled and rotated clockwise (arrow B ₁ direction) around the shaft 2a, the right end 2
The connecting rod 20 is pushed down ( _{in the two} directions of arrow B) via the connector 21 pivotally connected to the connector 21.
As a result, the link member 30 is rotated counterclockwise (arrow B ₃ direction) around the pivot shaft 5a, and this movement is transmitted to the intermediate link 9 and the open lever 5 via the pin 6, and The link 9 is pushed down (arrow _B4 direction), and the open lever 5 is rotated counterclockwise (arrow _B3 direction).
Here, if the link member 30 is not pivotally connected to the pivot shaft 5a, when the connecting rod 20 moves downward,
Since the adjuster clip 3 is rotatably attached to the link member 30, its connection rod 20
Due to the downward movement of the link member 30, the link member 30 is tilted about the pin 6, resulting in a situation in which the downward stroke of the connecting rod 20 cannot be effectively transmitted to the pin 6 (open lever 5, intermediate link 9). Above intermediate link 9
As a result of the downward movement of , the hook (lock mechanism) of the lock portion 8 is disengaged from the striker on the vehicle body side, and the door 10 is opened. In addition, since the open lever 5 is rotated in the direction away from the inner lever 7,
Even if the outer handle 2 is operated, the inner handle does not move.

On the other hand, when operating the inner handle,
As shown in FIG. 3, the inner lever 7 is rotated clockwise (arrow _B5 direction), and the right end 5b of the open lever 5 that comes into contact with it is pushed up, and the open lever 5 is rotated counterclockwise (arrow B5 direction). ₍₆ directions). By rotating the open lever 5, the intermediate link 9 is moved downward (arrow) together with the pin 6.
B ₇ direction) to disengage the hook from the striker and open the door. At this time,
The pin 6 is inserted into the elongated hole 31 of the link member 30.
The link member 30 is not moved and the outer handle 2 is not moved.

(Effects of the invention) As explained above, in the present invention, a link member is provided which is connected with an open lever and an elongated hole with a predetermined play, and the link member and the connecting rod are connected with an ajar. Since the lock device is constructed by attaching the adjuster clip, the adjuster clip can be placed near the lock regardless of the position of the outer handle. Therefore, the adjustment clip can be positioned near the opening of the inner panel, making it easier to adjust the mounting position of the locking device, and improving the workability of mounting the locking device. In addition, since the adjuster clip is attached to the link member so that it can rotate around an axis that is approximately parallel to the pivot axis to the lock portion of the open lever, manufacturing errors and assembly errors in each part may occur during assembly. Even if a relative rotational positional deviation occurs between the connecting rod and the link member due to such reasons, the positional deviation can be absorbed by the rotation of the adjuster clip.
In order to connect the connecting rod and the link member, there is no need to rotate the link member around its elongated hole to absorb the above-mentioned positional deviation, and therefore the direction of the link member and the elongated hole is adjusted to match the rotation of the open lever. It is possible to avoid deviation from the preset direction based on the movement trajectory, etc., and thus ensure smooth door lock release operation. Additionally, when the adjuster clip is rotatably attached as described above, the link member is moved in two places, the adjuster clip part and the elongated hole part of the link part, in the process of transmitting the downward stroke of the connecting rod to the open lever. As a result, when the connecting rod makes a downward stroke, the link member is tilted and the downward stroke of the connecting rod cannot be accurately transmitted to the open lever via the link member. To solve this problem, in the present invention, the link member is pivotally connected to the pivot shaft of the open lever as described above, so that the movement of the link member is limited to rotation around the pivot shaft. Free tilting displacement of the member is no longer possible, which makes it possible to accurately transmit the downward stroke of the connecting rod to the open lever via the link member, making it possible to rotate the adjusting clip as described above. Even if the door is attached, the door lock can be reliably released.
