[0015]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of a handle structure for a sliding door for an automobile according to the present invention will be described using the same reference numerals for members that are substantially the same as or correspond to those of a conventional example, based on the drawings.
In this embodiment, the sliding door 100 is provided on a side portion of the body and is supported so as to be slidable back and forth along a guide rail laid on a predetermined part of the body. Further, it is assumed that an opening (entrance / exit) opened on the side surface of the body is opened and closed by the sliding operation of the sliding door 100.
[0016]
FIG. 1 shows the vicinity of a door handle in the embodiment of the present invention. An outer handle 10 is provided outside the slide door 100. As described above, the front lock mechanism 102 and the rear lock mechanism 103 are disposed before and after the slide door 100, and the open lock mechanism 104 is disposed below the slide door 100, respectively. These lock mechanisms are operated by a lock device 105 that interlocks with the movement of the outer handle 10 and the inner handle.
[0017]
In FIG. 1, an outer handle 10 operatively supported in a direction aligned with the opening / closing direction of the slide door 100, and a link mechanism coupled to the outer handle 10 and configured to drive the lock mechanisms 102, 103, 104. And the operation direction of the outer handle 10 for opening and closing the sliding door 100 matches the opening and closing direction of the sliding door 100.
[0018]
The base end side of the outer handle 10 is supported by the door base 11 so as to be rotatable and slidable. In this case, a long hole 12 is formed at the base end of the outer handle 10 along the front-rear direction, and a pin 13 that engages with the long hole 12 is implanted in the door base 11.
[0019]
The link mechanism operates in response to the rotation operation and slide operation of the outer handle 10.
The link mechanism includes a first link 15 rotatably supported on the door base 11 via a pin 14 and a second link rotatably coupled to the distal end side of the outer handle 10 via a pin 16. 17, and these links 15 and 17 are connected to each other via a connecting pin 18.
[0020]
The first link 15 is connected to the front lock mechanism 102 and the rear lock mechanism 103 via a rod 19. The second link 17 is connected to the open lock mechanism 104 through the rod 21 in the long hole 20.
[0021]
In the above configuration, an operation procedure when the door is opened will be described first. In this case, when the slide door 100 is closed, the outer handle 10 arranged as shown by the solid line in FIG. 1 is grasped and pulled outward as it is, and is rotated around the pin 13 like a two-dot chain line. As a result, when the link 17 is pulled outward in conjunction with the movement of the outer handle 10, the link 15 connected to the link 17 via the connecting pin 18 rotates around the pin 14 in the clockwise direction in the figure.
[0022]
The rod 19 is pulled by the rotation of the link 15, and as a result, the front lock mechanism 102 and the rear lock mechanism 103 are released. In this case, as shown in FIG. 3, the rod 19 acts on the lock device 105, and the front lock mechanism 102 and the rear lock mechanism 103 are released via the lock device 105. During this time, the open lock mechanism 104 does not operate.
[0023]
By releasing the front lock mechanism 102 and the rear lock mechanism 103, the outer handle 10 can be pulled backward, and the slide door 100 can be opened by operating the handle.
[0024]
The pin 14 is provided with a return spring (which may be a coil spring) (not shown) around its axis. As described above, after unlocking the front lock mechanism 102 and the rear lock mechanism 103, the outer handle 10 is returned to the original position (solid line in FIG. 1) by the elasticity of the return spring.
[0025]
Next, when the sliding door 100 is closed contrary to the above, when the sliding door 100 is open, the outer handle 10 arranged as shown by the solid line in FIG. Slide forward. Thus, in conjunction with the movement of the outer handle 10, the link 17 rotates around the connecting pin 18 in the counterclockwise direction in the drawing. Thereby, the long hole 20 of the link 17 also moves backward like a two-dot chain line.
[0026]
Here, a rod 21 is connected to the long hole 20 via a washer 22 as shown in FIG. As the long hole 20 moves rearward, the rod 21 is pushed, and as a result, the open lock mechanism 104 is released. In this case, as shown in FIG. 6, the rod 21 acts on the lock device 105, and the open lock mechanism 104 is released via the lock device 105. During this time, the front lock mechanism 102 and the rear lock mechanism 103 do not operate.
[0027]
When the open lock mechanism 104 is released, the outer handle 10 can be pulled forward, and the slide door 100 can be closed by this handle operation.
[0028]
As shown in FIG. 4, a return spring 23 (which may be a tension coil spring) is attached to the outer handle 10. The outer handle 10 is returned to its original position (solid line in FIG. 4) by the elasticity of the return spring 23.
[0029]
By matching the door moving direction when the sliding door 100 is opened and closed and the operation direction of the outer handle 10 as described above, the sliding door 100 can be opened and closed by an operation that matches the movement of the sliding door 100. Therefore, since the operation of the outer handle 10 is easy to understand and only one motion is required, extremely excellent operability can be realized. In this case, the front lock mechanism 102 and the rear lock mechanism 103 or the open lock mechanism 104 are driven in response to the operation of the outer handle 10, and the handle operation can be performed with a substantially small amount of force.
[0030]
