Description

[Detailed Description of the Invention] The present invention relates to an opening regulating device for a vehicle opening/closing body.

An example of an opening/closing device for a vehicle opening/closing body is an opening/closing device for a back door of an automobile.In such an opening/closing device, when the back door is opened to the maximum opening position, When a long object is loaded on the upper side, the back door and the loaded object may interfere with each other and damage the back door.

In order to eliminate the above-mentioned drawbacks, the present invention has developed an opening/closing body for a vehicle that can selectively lock and hold an opening/closing body such as a back door at an opening position on the near side of the maximum opening position. The purpose of this invention is to provide an opening regulating device.

Hereinafter, the present invention will be explained with reference to illustrated embodiments.

In FIG. 1, reference numeral 1 indicates a back door whose base end is rotatably supported on the vehicle body side of the automobile by a hinge (not shown), and a gas station is provided between the back door 1 and the rear pillar 2 of the vehicle body. 3 are connected. This gas stay has recently come to be commonly used as a balancer for relatively heavy doors.

As shown in FIG. 2, the lower end of the piston rod 3A of the gas stay 3 is attached to a mounting member 6 which is attached to the support member 4 via a pin 5 so as to be able to swing and turn. The stopper member indicated by the reference numeral 7 and the support member 4 are fastened together by a bolt 8, and by screwing the bolt 8 which performs this joint tightening into the rear pillar 2 shown in FIG. Fixedly held at 2.

As shown in FIG. 4, the upper end of the cylinder 3B of the gas stay 3 is fixed to a mounting member 10, and this mounting member 10 is mounted via a pin 11 to a support member 12 so as to be swingable and pivotable. In addition, support member 1
2 is fixedly attached to the back door 1 shown in FIG.

The cylinder 3B is in contact with a metal rod 13 arranged side by side in the longitudinal direction, a wire 14 is inserted through the rod 13, and the wire 14 and the rod 13 are fixed to each other. There is. One end of a wire 14 passing through the rod 13 and extending from the upper end of the rod 13 is locked to the mounting member 10 as a fixed end.

On the other hand, the piston rod 3 is connected from the lower end of the rod 13.
The other end of the wire 14 extending toward the fixed end side of A is a free end, and this free end is provided with a protrusion 15 as a locked portion that is locked to the stopper member 7 as described later. ing.

As shown in FIGS. 4 and 5, the cylinder 3
B and the rod 13 are held fixed to each other by a flexible tube 16 such as a vinyl tube.

On the other hand, as shown in FIG. 2, a hook-shaped curved piece 7a is formed on the stopper member 7, and a wire 14 is inserted into this curved piece 7a. Note that the wire 14 can be inserted into and removed from the inside of the curved piece 7a.

Here, in FIGS. 1 and 2, assuming that the wire 14 is inserted through the curved piece 7a of the stopper member 7, when the back door 1 is opened from the closed position to the maximum opening position, at this time, Since the rod 13 moves integrally with the cylinder 3B of the gas stay 3, the wire 14 gradually rises, and finally the protrusion 15 is locked to the lower end of the curved piece 7a of the stopper member 7. In this state,
The back door 1 is placed at an opening position closer to this side than the maximum opening position, and cannot be opened successively from this position. That is, opening of the back door from the front opening position to the maximum opening position is restricted.

Now, assuming that the back door 1 is opened to the maximum opening position, as mentioned earlier, if a long object is loaded on the top of the roof of the car, the back door and the loaded object will Interfering with each other and damaging the back door.

The present invention prevents such problems. Note that when there is no loaded object on the upper side of the roof, the wire 14 is connected to the curved piece 7 as shown in FIG.
By pulling the door out from inside a in the direction of the arrow, the above-mentioned opening restriction of the back door is released, and the back door can be opened to the maximum opening position.

By the way, in this devised device, rod 1
3, wire 14, stopper member 7, etc. can be easily added as options, and there is also the advantage that there is no need to make any changes to the vehicle body or the panel structure on the back door side.

In addition, as another embodiment, the wire may be a rope-like body or a belt-like body made of resin (for example, nylon), and the wire 14 may be connected to the cylinder 3B without using the metal rod 13. It may also be applied directly to the

In addition, in the embodiment shown in FIG. 2, the stopper member 7 and the support member 4 are constructed separately, but they may be integrally molded. It is also possible to have a configuration as shown by the reference numeral 17 in FIG. Furthermore, the present invention can also be applied to an opening/closing structure in which the gas stay 3 shown in FIG. 1 is installed upside down.

As described above, according to the present invention, the opening position of the opening/closing body can be set to the maximum opening position or the opening position on this front side. No mutual interference will occur. An opening regulating device for a vehicle opening/closing body can be provided.
