Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a safety lock device for a sliding door in a vehicle, and more specifically, when the window glass is open, the door handle is operated when the knob lock is not lowered. This invention relates to a safety lock device for a sliding door that prevents the door from being unlocked and the sliding door from being opened.

Sliding doors in conventional vehicles are provided with sliding window glasses that can be opened and closed manually. This window glass is designed to open regardless of whether the sliding door is open or closed, so if the window glass is opened while the vehicle is stopped, if you accidentally pull up the rod knob and operate the door handle, the sliding door will open. The problem was that it would open.

Furthermore, since the sliding door and window glass are opened and closed separately, there is a problem that there is a risk of theft if the driver forgets to close the window when getting off the vehicle.

Therefore, in view of these conventional problems, when the rod knob is pushed down and the window glass is opened, the rod knob operation is linked, and even if the door handle is operated, the door lock will not be released and the sliding door will not be unlocked. There is a sliding door safety lock device that solves the above problem by preventing the door from being opened.

Examples of such a safety lock device for a sliding door include those shown in FIGS. 1 to 4.

In the figure, 1 is a vehicle, and 2 is a sliding door attached to the body of the vehicle 1. A sliding door 2 is provided with double-sliding window glasses 3 on a window frame 4. The window glass 3 consists of a fixed glass 3a fixed to a window frame 4 and a slide glass 3b slidable on the window frame 4, and the slide glass 3b is slid by a glass drive device 5 provided on the sliding door 2.

Further, the sliding door 2 is provided with a door handle 6 and a 3-door lock device 7 that is unlocked by opening the door handle 6. Further, the sliding door 2 is provided with a rod knob 8 that moves up and down to maintain the locked state of the door lock device 7 with the vehicle body and to maintain the locked state of the door lock device 7 even when the door handle 6 is opened. It is being A knob lock 8a is attached to the tip of the rod knob 8.
is provided.

Further, the sliding door 2 has a stopper function that is operated in conjunction with the vertical movement of the rod knob 8 to prevent the sliding glass 3b from sliding by the glass drive device 5, and a stopper function that prevents the sliding glass 3b from sliding and the window glass 3 opening. A stopper rod knob has a locking function that holds the operating state of the rod knob 8 when the window glass 3 is closed, and releases the holding of the operating state of the rod knob 8 when the windshield 3 is closed to make the rod knob 8 movable for operation. A blocking device 9 is provided.

The glass drive device 5 includes a drive wire 12 that moves linearly by rotation of a regulator handle 11 attached to the sliding door, and transmits the linear motion of the drive wire 12 provided at the tip of the drive wire 12 to the slide glass 3b. It is composed of a drive transmission device 13. The drive transmission device 13 has a base plate 15 fixed to the tip of a drive wire 12 movably disposed within a channel material 14 provided in parallel to the window frame 4.
Attach the swing lever 16 to the swing lever 1.
A glass support 17 having a guide roller (not shown) is provided at the end of the glass support 6 .

The guide support 17 supports the lower end of the slide glass 3b, and the guide roller is attached to the window frame 4 by the channel material 1.
It is fitted into a guide rail (not shown) provided in parallel with 4.

When the regulator handle 11 is rotated, the glass drive device 5 operates so that the drive wire 12 moves within the channel material 14 and the slide glass 3b is slid via the drive transmission device 13 accordingly. A foot lever 18 is provided on the base plate 15 of the drive transmission device [113].

The door handle 6 and the rod knob 8 are connected to the door lock device 7 via the door lock remote control unit 20, respectively.
It is connected to the. The door lock remote control unit 20 includes a two-pronged safety lever 22 that is swung by a rod 21 connected to the door handle 6, an operating lever 24 that is rotated by a rod knob 8,
A bell crank lever 26 is connected to the door lock device 7 and is swung by a rod 25 that has a link 23 in the middle, and one end is rotatably connected to the operating lever 24 and the other end is connected to the L-shape of the safety lever 22. shaped through hole 22
A connecting lever 28 is connected to a bell crank lever 26 by a guide pin 27 passing through a.

When the door handle 6 is operated when the rod knob 8 is not operated and the door lock remote control section 20 is in the upward position, the safety lever 22 swings, and the bell crank lever 26 also swings accordingly, so that the door lock device 7 is in the locked state. Release. However, when the rod knob 8 is operated and does not move, even if the door handle 6 is operated, the safety lever 22 swings, but the safety lever 22 swings the bell crank lever 26 due to the through hole 22a provided in the safety lever 22, causing the bell crank lever 26 to swing out. The crank lever 26 is not swung, and the door lock device 7 remains locked (
(doors are locked).

The stopper rod knob locking device 9 has a stopper operating lever 31 that is rotated by a rod 30 connected to the other end of the operating lever 24, a pair of bifurcated stopper portions 32, 32 on one end side, and other parts. Stopper operation lever 3 on the end side
and a stopper lever 34 having an L-shaped lock hole 33 into which a pivot pin 31a provided at one end engages. A pair of stopper parts 3 of the stopper lever 34
2.32 is engaged with the foot lever 18 of the drive transmission device 13.

A safety lock device having such a configuration is used for sliding door 2.
is closed, and when the knob lock 8a is operated to move the rod knob 8 downward in the direction shown by the arrow in FIG. rotates counterclockwise, that is, upward;
Correspondingly, the rod 30 moves upward, causing the end of the stopper operating lever 31 to which the rod 30 is connected to rotate upward. The end portion where 7- is provided moves downward, and the pivot pin 31a moves from the vertical portion 33a of the lock hole 33 of the stopper lever 34 to the horizontal portion 33b. Therefore, the lock by the lock hole 33 between the stopper lever 34 and the collar 32.32 is released, and the stopper lever 34 can be rotated. Enables the device 13 to be driven.

Therefore, in order to open the window glass 3, when the regulator handle 11 of the glass drive unit W5 is rotated, the drive wire 12 moves, and the drive transmission unit @13 moves rearward, that is, in the direction of opening the window. The lever 18 moves to the foot 1 and kicks the stopper portion 32 of the stopper lever 34. Then, the stopper lever 34 swings from the two-dot chain line position to the solid line position as shown in FIG. 4, the drive transmission device 13 continues to move, the slide glass 3b slides, and the window glass 3 is opened. in this way,
When the rod knob 8 is not moving, the window glass 3 can be opened. However, even if the door handle 6 is operated, the safety lever 22 swings, but the safety lever 22 swings the bell crank lever 26 due to the interceptor 22a provided on the safety lever 22, and the bell crank lever 26 is not allowed to swing. Therefore, the door lock of the door lock device 7 is not released, and the sliding door 2 cannot be opened.

Furthermore, when the window glass 3 is closed, the foot lever 18 of the drive transmission device 13 kicks the stopper part 32 on the front side of the stopper lever 34, swinging the stopper lever 34 to return to the original position indicated by the two-dot chain line. let Therefore, the rod knob 8 can be moved upward, and when the rod knob 8 is moved upward, the operating lever 24 is rotated clockwise and the connecting lever 28 is also moved downward, and when the safety lever 22 is swung, Since the bell crank lever 26 is set to swing, when the door handle 6 is operated, the safety lever 22 swings, and the bell crank lever 26 swings accordingly to lock the door of the door lock device 7. If it is released and the sliding door 2 is allowed to slide as it is, the sliding door 2 will be opened. Therefore, when the window glass 3 is open, the sliding door 2 will not open even if the door handle 6 is operated, and the occupant can be reliably protected. Furthermore, since the sliding door 2 can be opened when the windshield 3 is closed, it is no longer necessary to forget to close the windshield 3 when getting off the vehicle.

Furthermore, when the rod knob 8 is pulled up to open the sliding door 2 with the window glass 3 open, the pivot pin 31a of the stopper operation lever 31 is inserted into the horizontal portion 33b by the lock hole 33 of the stopper lever 34. There it is,
Since the stopper operating lever 31 is set in a locked state, the operating lever 24 cannot be rotated clockwise.

Therefore, even if you try to pull up the rod knob 8, the rod knob 8 cannot be pulled up, and even if you operate the door handle 6 in the same way as when the rod knob 8 does not move, the sliding door 2
I can't open it. Wind glass 3 like this
When the window is opened, even if an attempt is made to operate the rod knob 8, the rod knob 8 will not operate and the sliding door 2 will not open.

Also, if the sliding door 2 is closed and the knob lock 8
When the rod knob 8 is in the upward movement position without operating a, the hook lever 18 of the drive transmission device 13 moves to the stopper portion 32 on the rear side of the stopper lever 34, as shown in FIG.
is engaged in. Therefore, even if an attempt is made to open the drive transmission device 13 by rotating the regulator handle 11, the hook lever 18 will be moved to the rear stopper portion 3.
2 and try to rotate the stopper lever 34, but the pivot pin 31a of the stopper operation lever 31 is in the vertical part 33a of the lock hole 33, and the stopper lever 31 is set in a locked state that does not rotate. Therefore, the stopper lever 31 cannot rotate. Therefore, rearward movement of the drive transmission device 13 is blocked by the stopper portion 32, and the window glass 3 cannot be opened.

However, in such a safety lock device, when the windshield 3 is opened, the opening/closing of the windshield 3, the operation of the front top 8, and the operation of the hair handle 6 are linked. However, since the door lock of the door lock device 7 is not released even if the door handle 6 is operated, the operation procedure is somewhat complicated.

Therefore, we simplified the operation procedure and created a safety system that prevents the door lock from being released even if the door handle is operated, regardless of the rod knob operation, and the sliding door cannot be opened when the window crow is opened. A locking device was requested.

This invention was made with attention to such a demand, and is driven by the rotational operation of the regulator handle.

connected by.

The connecting member 51 includes a two-pronged safety lever 53 that is swung by a rod 52 that is connected to the door handle 49, and a bell that is swung by a rod 55 that is connected to the door lock device 50 and has a link 54 in the middle. An L-shaped through hole 53a and an L-shaped through hole 53a provided in the crank lever 56 and the safety lever 53 connect the bell crank lever 56 so that the bell crank lever 56 swings or does not swing when the safety lever 53 swings. The connecting pin 56b is engaged with the through hole 53a and fitted into the elongated hole 56a of the bell crank lever 56.

Further, the sliding door has a connection that is activated by the drive transmission device 43 when the window glass 40 is opened, and operates the connection member 51 so that the operating force from the door handle 49 cannot be transmitted to the door lock device 50. A member transmission release mechanism 57 is provided.

The connecting member transmission release mechanism 57 includes a link lever 58 that is pivotally supported by a connecting pin 56b that engages with the through hole 53a, and a rotatable operating lever 59 that is pivotally supported by the link lever 58.
and a pair of bifurcated stopper portions 6]a connected to the operating lever 59 via a horizontal roller 0, 61. The stopper lever 61 has a swingable stopper lever 61. A pair of stopper parts 61a, 6 of the stopper lever 61

In addition, the sliding door has a rod knob that moves up and down, which is not linked to the operation of the door handle 49, and which independently maintains the locked state of the door lock device 50 with the vehicle body (i.e., locks the door) or releases the door lock. 63 are provided. An f-lock 63a is provided at the tip of the rod knob 63.

Next, the effect will be explained.

First, a case will be described in which the door handle 49 is operated while the window glass 40 is closed.

Operate the door handle 49 as shown by the arrow in Figure 5 10
- When pulled toward the front of the vehicle, the rod 52 also moves in the direction shown by the arrow, and the safety lever 53 also moves to
) swings toward the front of the vehicle from the state shown in (b) to the state shown in (b). At this time, the long hole 56 of the bell crank lever 56
The connecting pin 56b fitted in the hole 53a of the safety lever 53 is located at the vertical part of the through hole 53a of the safety lever 53.
As the safety lever 53 moves, the connecting pin 56b also follows and the connecting member 51 can transmit the operating force from the door handle 49 to the door lock device 50.
When the bell crank lever 56 swings, the bell crank lever 56 moves the rod 55 to release the door lock of the door lock device 50, and if the sliding door is slid as it is, the sliding door will be opened. It will be done.

Note that when the rod knob 63 is pushed down and the door lock device 50 is locked, the door handle 4
Even if I operate 9, the sliding door will not open.

Next, a case will be described in which the door handle 49 is operated while the window glass 40 is opened.

In order to open the windshield 40, when the regulator handle of the glass drive 16-device is rotated, the drive wire 42 moves, and the drive transmission device 43 accordingly moves toward the rear of the vehicle, that is, in the windshield opening direction. 1-The lever 48 is located at the rear side of the stopper lever 61 in the stopper portion 6],
kick a. Then, the collar lever 61 swings backwards as shown by the arrow in FIG. The link lever 58, one end of which is pivoted to the operating lever 59, moves upward. The other end of the link lever 58 is pivotally supported by a connecting pin 56b passing through the through hole 53a of the safety lever 53, so that when the link lever 58 moves upward, the connecting pin 56
b is moved from the vertical part to the horizontal part of the through hole 53a and is located in the horizontal part. In this way, the connecting member transmission release mechanism 5
7 operates the connecting member 51 so that the operating force from the door handle 49 cannot be transmitted to the door lock device 50.

Therefore, when the door handle 49 is operated to pull the vehicle forward, the safety lever 53 swings in the same manner as described above.

At this time, the connecting pin 56b is located at the horizontal part of the through hole 53a, and since only the through hole 53a moves and the connecting pin 56b remains stationary, the safety lever is moved as shown in FIG. 7(C). 53 swings the bell crank lever 56 in vain, the bell crank lever 56 cannot be swung, and the door lock of the door lock device 50 is not released. Therefore, the sliding door cannot be opened. In addition, the rod knob 63
Even when the door lock device 50 is not pressed down and the door lock device 50 is not locked, the sliding door will not be opened even if the door handle 49 is operated. - In this way, when the window glass 40 is closed,
The connecting member 51 is set so that the operating force from the door handle 49 can be transmitted to the door lock device 50, and when the door handle 49 is operated, the door lock of the door lock device 50 is released and the sliding door can be opened. Because you can
There is no need to forget to close the window glass 3 when getting off the vehicle.

Further, when the window glass 40 is opened, the connecting member transmission release mechanism 57 is activated, and even if the connecting member 51 applies the operating force from the door handle 49 to the door handle 49, the door lock of the door lock device 50 is released. Since the sliding door cannot be opened, the occupants can be reliably protected. In this case, the rod knob 63 is not pushed down and the sliding door cannot be opened even if the door handle 49 is operated even when the door lock device 50 is not locked. Since it is not linked to the operation of , the operation procedure is simple and the operation is reliable.

Furthermore, when opening the sliding door with the window glass 40 open, the rod 55 is moved by operating the door lock release operation lever 62 disposed within the trim of the sliding door. Door lock device 5
0's door lock is released and the sliding door is opened.

In this embodiment, the window glass 4 is attached to the sliding door.
Although the invention has been described with respect to a case in which the window glass slides left and right, it goes without saying that the present invention can also be applied to a case in which the window glass slides up and down.

90- As explained above, according to the present invention, there is provided a drive transmission device that is driven by the rotational operation of a regulator handle and slides a window glass provided in a sliding door, and a drive transmission device that slides a window glass provided in a sliding door when the sliding door is closed. A door lock device that locks the vehicle body and unlocks when the door is opened, and a door lock device that is interposed between a door handle provided on the sliding door and the door lock device, and that receives the operating force from the door handle. a connecting member capable of transmitting or not transmitting information to a door lock device, and actuated by the drive transmission device when the window glass is opened;
Since the sliding door safety lock device is configured to include a connecting member transmission release mechanism that operates the connecting member so that the operating force from the door handle cannot be transmitted to the door lock device, the window glass is closed. In this case, the connecting member is set so that the operating force from the door handle can be transmitted to the door lock device, and the door lock of the door lock device is released by operating the door handle, so the sliding door is opened and the driver exits the vehicle. This has the effect of preventing forgetting to close the window glass and theft at times.

Conversely, when the window glass is closed, the coupling member transmission release mechanism is activated and the coupling member is set so as to be unable to transmit the operating force from the door handle to the door lock, thereby operating the door handle. Since the door lock of the door lock device will not be released even if the door lock is opened, the sliding door will not be opened, and there is no longer a risk that the sliding door will open if the door handle is operated when the window glass is opened as in the past. , the effect of reliably protecting the occupants can be obtained. Moreover, since it is not linked to the operation of the rod knob, the configuration is simple, the operation procedure is also simple, and reliable operation can be achieved.
