Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a full-open lock device for a sliding door device for an automobile.

In the case of a conventional sliding door, in order to maintain the sliding door in a fully open state, a checker, which is similar to an elastic protrusion, is provided on the roller running surface at the rear end of the lower guide rail. Although the roller on the lower side is engaged with the checker, the checker alone is insufficient to prevent the sliding door from running out of control on a slope, for example, so a locking device as shown in Fig. 4 is used. was previously proposed by the present applicant and others.

. That is, Figures 2 to 4 illustrate the case of a so-called center pillar-less car that has a hinge type front door and a sliding type rear door as shown in Figure 1, and a lower guide installed on the side sill of the car body. At the rear end of the rail 1, a checker 2 with an elastic protrusion is provided on the running surface of the seventh roller, and when the sliding door 3t is fully opened, Vc is a guide roller that is pivotally supported by the roller bracket 4 on the sliding door 8 side. 5 climbs over and engages with the checker 2, thereby keeping the sliding door 8 fully open. On the other hand, a striker 7 is fixed to the rear end of the center guide rail 6 installed at the waist of the vehicle, and a hook 9 is rotatably supported on a roller bracket 8 on the center side. In addition to the checker 2, the hook 9 is configured to engage the striker 7.

According to the above configuration, the sliding door 3 can be maintained in the fully open state with full certainty unless the engagement between the seven claws 9 and the striker 7 is released, and the sliding door 3 can be kept completely open even on a slope, for example. That's not it.

When closing the door, the operating rod 1 can be operated by operating the lock release handle, which is coaxially provided with the door handle (not shown).
0 is pulled and the hook 9 rotates clockwise, thereby releasing the engagement with the striker 7.

However, according to the above structure, when the lower row 25 engages with the checker 2, the hook 9 engages and comes into contact with the striker 7, so it is released when the sliding door is closed. The sliding door must be moved further in the opening direction while operating the handle to disengage the hook 9 and the striker 7, and then the door must be pulled forward, resulting in poor operability.

In view of the above-mentioned points, the present invention has been made with the sole purpose of improving the release operability of the fully open lock device.With this purpose in mind, in the present invention, when the sliding door is fully open, that is, when the guide roller is While engaged with the checker that maintains the fully open state, the hook installed on the sliding door side and the striker installed on the guide rail side face each other with a certain clearance, and the sliding door is moved in the opening direction. Only when the door moves, the hook and the striker are engaged to restrain the closing door, and the hook can be released from the opposite position by operating the lock release handle in a no-load state.

Hereinafter, one embodiment of the present invention will be described based on the drawings, with the same parts as those of the conventional example being denoted by the same reference numerals.

That is, even in this embodiment, the structure of the checker 2 that falls on the lower guide rail is the same as that shown in FIGS. 2 and 8, and the details are as described above. When the sliding door 3 is fully open, The guide roller 5 crosses over the checker 2 and engages with it. The full-opening locking device in this embodiment is shown in Figure 2, and includes the center roller bracket 8 of the sliding door 311111.
The relationship between the fixed hook 9, which is pivotally supported by the center guide rail 6, and the striker 7 provided at the rear end of the center guide rail 6 is such that a clearance of several millimeters is established between the hook 9 and the striker 7 when the sliding door is fully open. The rotation of the hook 9 is restricted to 1: to prevent the two from directly touching each other. That is, the rotation is restricted by the return spring 11 which urges the hook 9 to rotate counterclockwise in Figure 5 and holds it in the free state at the solid line position in Figure 2.

When the door is fully open, the clearance Q is operatively connected to the hook 8 and the lock release knob.
The dimensions are such that when the hook 9 is rotated counterclockwise in FIG. 6 against the return spring 11, the hook 9 can be rotated to the position shown by the dashed line independently of the striker 7.

12 is a guide roller on the center side, and 1B is an arm connecting the sliding door 8 and the roller racket 8.

Therefore, according to the above configuration, when the door is closed, there is no contact with the striker 0 or the striker 7 and there is almost no load, so the leg v1 hook 9 is moved to the IH immediately via the actuating rod IO with only an extremely small operating force. It rotates to position O shown by the dashed line in the figure. Then, the slide door 8 is opened with enough operating force to allow the guide roller 6 to pass over the checker 2.
When the door is pulled in the closing direction, immediate door closing operation is achieved.

In addition, in the above example, all checkered lower guide rails are
Although strikers are shown provided on all center guide rails, both checkers and strikers may be provided on the lower guide rail. In this case, the hook attaches to the lower guide roller racket.

As described above, according to the present invention, it is possible to improve the release operability of the full-open lock device without impairing its original function, and there is an effect that it can contribute to improving the opening/closing performance and safety of the sliding door.
