DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automobile door lock device, and particularly to the structure of its locking/unlocking mechanism.

A conventional automobile door lock device is generally shown in FIG.

This conventional device has a vertical board b fixed to the inner surface of the free end of the door a, and is pivoted to the board b with an axis c, and rotates clockwise in FIG. 1 (hereinafter referred to as the release direction). Accordingly, an open lever d for releasing the engagement between the vehicle body and the door is pivotally connected to the base plate b with an axis e, and a rod or the like is attached to an inside handle and an outside handle (both not shown). The upper end of the operating lever f is pivoted to a portion of the operating lever f that is spaced to the right from the axis e of the operating lever f, which is linked and rotated in the clockwise release direction in FIG. 1 by their release operations. It also has an engaging part g that can engage and disengage with the open lever d in the middle part, and the lower end rotates between the unlocked position shown in solid lines in FIG. 1 and the locked position shown in imaginary lines in FIG. When it is in the unlocked position, by rotating the operating lever f in the releasing direction, the open lever d can be rotated in the releasing direction using the engaging part g, and the locking position can be moved. In some cases, a sub-lever h whose engaging portion g is disengaged from an open lever d, and a locking/unlocking member i are provided.

Thus, the locking/unlocking member i is pivotally attached to the base plate b with an axis j, and a pin k protruding from the middle portion is slid into a long hole l in the vertical direction drilled in the sub-lever h. By freely engaging the sub lever h
and a key device m and a lock/unlock knob n
The sub-lever h is linked with the rods o, p and the auxiliary lever q, etc., and is moved to the unlocked position by the locking/unlocking operation of the key device m or the locking/unlocking knob n. and a locked position shown by imaginary lines in FIG. 1, which positions the sub-lever h in the locked position.

However, in the conventional device with such a configuration, when the door is in the locked state, a thin plate is inserted between the wind glass r and the door panel s, and this thin plate allows the rods o and p, the auxiliary lever q, or the locking/unlocking member i to be The door can be opened by pivoting the door from the locked position to the unlocked position, and there is a risk that the lock could be easily broken and stolen by someone who has some knowledge of this type of mechanism.

Therefore, if we consider the cause of such a possibility of theft, we will find that the locking/unlocking member i and the auxiliary lever q are pivotally attached to the board b with a horizontal axis j, etc., and their respective ends are vertically oriented. The locked state can be easily released by pushing down (or pulling up) this end with some means from above, and rigid rods o and p are used as connecting members. Since the rods are being used, the insert must be secured to either part of the rods o or p.
It can be seen that the locking/unlocking member i can be operated by moving the locking member i.

Based on these considerations, the present invention aims to provide an automobile door lock device that can prevent the fear of theft as described above. The locking member is slidably attached to the board, and
This locking/unlocking member is connected to a key device and a locking/unlocking knob by an inner cable inserted into an outer case whose both ends are fixed to appropriate fixing parts.

The present invention will be explained below based on the embodiments shown in FIGS. 2 to 5.

2 and 3 show a first embodiment of the present invention.

1 is the door, 2 is the inner panel of door 1, 3
is also the outer panel.

A substantially vertical base plate 5 of a door lock device 4 is fixed to the inner surface of the free end of the door 1.

An open lever 7 is pivotally attached to the middle portion of the base plate 5 with a shaft 6. This open lever 7 has an engaged portion 7 that protrudes to the right in FIG.
a and an arm 7b projecting downward, the second
By being rotated in the release direction, which is clockwise in the figure, the pawl member provided on the rear surface of the board 5 is removed from the latch member (both not shown).
The door can be opened by disengaging the latch member from a striker (not shown) provided on the vehicle body.

At the center of the upper part of the board 5, an operating lever 9 is pivotally mounted with a shaft 8 and extends in the left-right direction. This operating lever 9 is connected to an inside handle and an outside handle (both not shown) provided on the inside and outside of the door 1 with appropriate rods (not shown), and when these are released, the lever shown in FIG. It is adapted to be rotated in a clockwise release direction.

In addition, the open lever 7 and the operating lever 9 are
Each is constantly biased counterclockwise by a spring (not shown).

Reference numeral 10 denotes a sub-lever that extends in the vertical direction, and its upper end is pivotally attached to a portion of the operating lever 9 to the right of the shaft 8. An engaging portion 10a that engages and disengages the engaged portion 7a of the open lever 7 is formed on the left edge of the middle portion of the sub-lever 10, and an extending portion 10b that extends leftward from near the lower end of the sub-lever 10 is formed. At the free end is the arm 7 of the open lever 7.
A contact portion 10c that can come into contact with the left side edge of the sub-lever 10 is formed, and a protruding piece 10d that faces downward is formed at the lower end of the sub-lever 10.

Thus, the sub-lever 10 can be rotated between the unlocked position shown in solid lines in FIG. By rotating it in the direction, it moves downward and pushes down the engaged part 7a of the open lever 7 with the engaging part 10a, and by rotating the open lever 7 in the releasing direction, the door can be opened. can. Furthermore, when in the locked position, the engaging portion 10a is disengaged from the engaged portion 7a of the open lever 7, and no matter how much the operating lever 9 is rotated in the releasing direction, the engaging portion 10a will only swing in vain. , the open lever 7 cannot be rotated.

The relationship between the arm 7b and the contact portion 10c is such that when the sub-lever 10 is in the locked position and the door is closed, the engagement between the ratte member and the pawl member causes
When the open lever 7 rotates clockwise in FIG. 2, the arm 7b comes into contact with the abutting portion 10c, and the sub-lever 10 is returned to the unlocked position, which is a so-called unlocking operation. By rotating the operating lever 9 in the release direction with the sub-lever 10 in the locked position, the contact portion 10c is removed from the rotational trajectory of the arm 7b, and by closing the door in this state, the door 1 can be opened without a key. This relationship allows for so-called keyless locking, in which the door is closed and locked at the same time.

11 is a locking/unlocking member, and this locking/unlocking member 11 is
Left and right 1 forming the left and right direction bored at the bottom of the board 5
Headed pins 13, 13 fixed to the lower surface are engaged with the pair of elongated holes 12, 12, respectively, so as to be slidably mounted on the substrate 5 in the left-right direction.

On the surface of the locking/unlocking member 11 opposite to the base plate 5, a pair of arc-shaped left and right protrusions 14, 14 which are constricted at the center are erected. 10 protruding pieces 10d are sandwiched in a vertically slidable manner.

In the space formed between the locking/unlocking member 11 and the base plate 5, there is provided an over-center spring 15 which is locked at one end to the base plate 5 and at the other end to the locking/unlocking member 11. Accordingly, the locking/unlocking member 11 holds the sub-lever 10 in the unlocked position, which is shown by solid lines in FIGS. 2 and 3, and holds the sub-lever 10 in the locked position. It is biased so as to be switched to either the locked position shown in phantom lines in FIGS. 2 and 3.

Pins 18 and 19, which are fixed to one end of each of flexible inner cables 16 and 17 made of wire or the like, are fixed to both left and right ends of the locking/unlocking member 11, respectively. Both inner cables 16 and 17 are
Flexible outer case 2 with bent middle part
0 and 21, respectively.

One end of the left outer case 20 is fixed to a bent piece 22 formed by bending the edge of the base plate 5 on the left side of the locking/unlocking member 11, and the other end of the outer case 20 is attached to a window of the door 1. It is fixed to the upper end bent portion 2a of the inner panel 2 forming a frame. Inner cable 16 inserted into outer case 20
The other end is fixed to a lock/unlock knob 23 provided on the upper end bent portion 2a of the inner panel 2 so as to be freely retractable.

One end of the right outer case 21 is fixed to a bent piece 24 formed by bending the edge of the base plate 5 on the right side of the lock/unlock member 11, and the other end of the outer case 21 is fixed to a bent piece 24 formed on the edge of the base plate 5 on the right side of the locking/unlocking member 11. It is fixed to an L-shaped bracket 27 fixed to the inner end of a key cylinder 26 in a key device 25 provided at a proper location.

The other end of the inner cable 17 protruding from the upper end of the outer case 21 is fixed to the free end of a key lever 28 which is rotated by a rotor (not shown) provided within the key cylinder 26.

Thus, either the lock/unlock knob 23 is pushed down and the inner cable 16 is pushed in, or the key device 2
Insert the key (not shown) into key lever 2.
By rotating the free end of 8 in the direction away from the bracket 27 and pulling the inner cable 17, the locking/unlocking member 11 can be brought to the locked position. In addition, by pulling up the locking/unlocking knob 23 and pulling the inner cable 16, or by pressing the key, the free end of the key lever 28 is rotated in a direction approaching the bracket 27, and the inner cable 17 is pushed into the outer case 21. , the locking/unlocking member 11 can be placed in the unlocked position.

In the first embodiment, as described above, the locking/unlocking member 11
is attached to the base plate 5 so as to be slidable in the left-right direction, which is substantially tangential to the rotation locus of the sub-lever 10, and the locking/unlocking member 11 is attached to an outer case whose both ends are fixed to appropriate fixing parts. 20, 21
Since the inner cables 16 and 17 inserted therein are connected to the lock/unlock knob 23 and the key device 25, a thin plate (not shown) can be inserted through the gap between the outer panel 3 of the door 1 and the window glass 29. It is impossible to move the locking/unlocking member 11 by inserting the thin plate.

Therefore, such an action makes it impossible to open the locked door 1 without a key, which is significant in terms of theft prevention.

4 and 5 show a second embodiment of the invention.

In the second embodiment, the locking/unlocking member 32 is engaged with the horizontal grooves 33 and 34 cut in the upper and lower surfaces of the locking/unlocking member 32 into the left/right elongated hole 31 drilled in the base plate 30. 32 is attached to the board 30 so as to be slidable in the left and right direction, and the locking/unlocking member 3
The locking/unlocking member 32 and the sub-lever 36 are linked by engaging the pin 35 protruding from the sub-lever 36 with the vertically elongated hole 37 drilled in the lower part of the sub-lever 36, and one end is connected to the locking/unlocking knob (not shown). ), and the other end is fixed to a key lever (not shown) in the key device, respectively.
The locking/unlocking member 32, the locking/unlocking knob, and the key device are interconnected by fixing the intermediate portion of the locking/unlocking member 32 to the locking/unlocking member 32 using appropriate fasteners 39, 40.

The other configurations are the same as those of the first embodiment.

In this second embodiment, similarly to the first embodiment, both the locking knob and the key device are used to move the locking and unlocking member 32 to the unlocked position shown in solid lines in FIG. The sub-lever 36 can be switched to any of the locked positions shown by the lines, and when it is in the unlocked position due to the engagement between the pin 35 and the elongated hole 37, the sub-lever 36 is placed in the unlocked position similar to that in the first embodiment. Furthermore, when in the locked position, the sub-lever 36 can be held in the same locked position as in the first embodiment, and the same functions and effects as in the first embodiment can be achieved.

Furthermore, in the second embodiment, the locking/unlocking member 3
2, the lock/unlock knob, and the key device can be connected with one inner cable, which has the advantage of a simple structure and easy assembly work.

As is clear from the above, the present invention is significant because it can prevent theft in which a locked door lock is unlocked from the outside without a key.

Furthermore, in the present invention, since the locking/unlocking member, the locking/unlocking knob, and the key device are connected to each other by an inner cable inserted into the outer case, the middle part of the outer case is bent in advance. As a result, even if the door panel deforms and comes into contact with the outer case in the event of an accident, the operation of the locking/unlocking member will not be hindered. There is no risk of inconveniences such as the locking/unlocking member becoming inoperable due to contact with the vehicle and the user being unable to escape from the vehicle.

Furthermore, the present invention has the advantage that members such as the auxiliary lever q in the conventional example shown in FIG. 1 can be omitted, and the structure can be simplified.
