Description

TECHNICAL FIELD The present invention relates to a check link mechanism for a vehicle door, and more particularly to a check link mechanism for a vehicle door. The check function is provided when the door is opened and the check function is not provided when the door is closed. About what you did.

2. Description of the Related Art In a vehicle such as an automobile, for example, as shown in FIG. 7, a double-door type door 2 supported by a side edge of a rear opening 1 of a vehicle body so as to be capable of laterally opening the rear opening 1 of the vehicle body. Some of them are provided so as to be opened and closed, and a check link mechanism for holding the door 2 open at a predetermined angle is provided between the door 2 and the peripheral edge of the vehicle body rear opening 1.

This check link mechanism is composed of a check arm 3 and a checker bracket 4 as shown in FIG. 6,
One end of the check arm 3 is pivotally supported on the vehicle body around the rear opening 1 of the vehicle body, and the other end of the check arm 3 is guided by a restriction groove 5 provided on the checker bracket 4 to move. The checker bracket 4 is attached to the door 2.

Then, the locking hole 6 is provided in the regulation groove 5 of the checker bracket 4.
Is provided, and the end portion of the check arm 3 is engaged with the locking hole 6 so that the door 2 is held in a state of being opened by a predetermined angle. This structure is shown, for example, in Japanese Utility Model Publication No. 62-201274.

However, in the above-described conventional vehicle door check link mechanism, the check arm 3 engages with the locking hole 6 not only when the door 2 is opened but also when the door 2 is closed. Since the check function works, the door 2
However, there is a problem that the operation of releasing the check function by disengaging the check arm 3 when the door is closed is troublesome.

Therefore, this invention is a vehicle door check that can improve the operability at the time of door closing operation by making the check function work when opening the door but not the check function when closing the door. It provides a link mechanism.

Means for Solving the Problem One end of a check arm is pivotally supported by either one of a vehicle body and a door, and the other end of the check arm is pivotally supported by a slider in a rail attached to either the door or the vehicle body, A hook is pivotally supported on the slider to lock the movement of the slider by locking it in a hole formed in the lower wall of the rail, and a hook is formed between the lower surface of the hook and the lower wall of the rail when the door is opened. A lock member is provided to allow the hook to be locked in the hole when the door is closed.

When the door is opened by the lock member, the hook is locked in the hole formed in the rail to hold the door closed at a predetermined angle, and when the door is closed, the hook is locked in the hole of the rail by the lock member. Is blocked and the door is closed with a single operation.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 5 shows an open / closed state of one door 9 that is laterally opened to the left and right, in which a pair of double doors 9 are attached to the side edges of the vehicle body rear opening 8 of the vehicle body 7.

A rail 10 is attached to the rear surface of the door 9 so as to extend in the vehicle width direction, and a slider 11 is slidably provided in the rail 10.

On the other hand, one end of the check arm 12 is pivotally supported on the inner wall of the vehicle body 7 which is the periphery of the rear opening 8 of the vehicle body, and the other end of the check arm 12 is pivotally supported by the slider 11.

Therefore, when the door 9 is opened, the slider 11 located on the pivot end side of the door 9 in the door closed state slides toward the pivot center of the door 9.

And, the slider 11 is the door opening with respect to the rail 10.
The door 9 is held at the opening operation at 90 ° and 180 °.

Specifically, as shown in FIGS. 1 to 4, the rail 10 has a U-shaped cross-section that opens to the side.
The slider 11 provided inside the slider 10 has a slider body 13 inside.

In the slider body 13, a hook 15 is pivotally supported by a shaft 14 of the slider body 13 which is perpendicular to the side wall 10a of the rail 10, and one end 15a of the hook 15 is located at a predetermined position (door opening angle 90 in the bottom wall 10b of the rail 10). It can be locked in a hole 16 formed at a position corresponding to °, 180 °.

On the other hand, a spring 17 is interposed between the other end 15b of the hook 15 and the slider body 13 so as to urge the one end 15a of the hook 15 in the direction of locking the hole 16. Further, a release rod 18 protruding laterally from the opening is attached to one end 15a of the hook 15 so that the hook 15
A notch 20 is provided in the opening lower edge 19 of the rail 10 so that the release rod 18 does not interfere with the rail 10 when the rail is locked in the hole 16 of the rail 10 by the fourth rod. See figure).

A notch 22 for receiving a lock member 21, which will be described later, is formed on the lower surface of the hook 15 on the one end 15a side.

A lock member 21 is provided on the slider body 13 so as to be movable in the slider body 13 across the hook 15.

The lock member 21 is a member having both ends loosely inserted in a long hole 23 formed in the slider body 13 and movable between the lower surface 15c of the hook 15 and the bottom wall 10b of the rail 10, and the lock member 21 is the slider 11. Is moved toward the center of rotation of the door 9 and is relatively moved toward the one end 15a side of the hook 15 and received by the notch 22 of the hook 15, and the one end 15a side of the hook 15 is locked in the hole 16 of the rail 10. The other end of the hook 15 at the time of the door closing operation in which the slider 11 moves to the rotating end side of the door 9.
It moves to the 15b side and prevents the one end 15a side of the hook 15 from being locked in the hole 16 of the rail 10.

According to the structure of the above embodiment, when the door 9 is opened from the fully closed position A of the door shown in FIG. 5, the lock member 21 relatively moves to the position shown by the chain line in FIG.

At this time, since the hook 15 is not in the position of the hole 16 of the rail 10, the slider 11 moves without locking the one end 15a with the bottom wall 10b.

When the one end 15a side of the hook 15 reaches the hole 16 of the bottom wall 10b of the rail 10, the release rod 18 falls into the cutout 20 of the opening lower edge portion 19 and the lock member 21 is received in the cutout portion 22 of the hook 15. Therefore, the hook 15 is not affected by the lock member 21,
One end 15a is locked in the hole 16 of the rail 10 and the door 9 is held at that position (90 ° open state B position).

Then, after releasing the holding state of the door 9 by pulling up the release rod 18, the door 9 is further operated to open,
When reaching the 0 ° open state C position, the door 9 is held in the open state at that position as in the B position.

Next, when the door 9 is closed, the release rod 18
When the door 9 is closed after pulling up the hook 15 to release the hook 15 from the locking state with respect to the hole 16, the rod member 21 relatively moves the elongated hole 23 to the position shown by the solid line in FIG.
One end of hook 15
Even if the a side reaches the position corresponding to the hole 16 of the bottom wall 10b of the rail 10, the hook 15 passes through the hole 16 of the rail 10 without being locked, and therefore the door 9 is closed without being locked until it is completely closed. is there.

Therefore, the door closing operation can be performed smoothly and quickly.

In addition, this invention is not limited to the above embodiment,
For example, the rail may be attached to the vehicle body side.
Further, the release rod may be brought into contact with the upper edge of the lower edge portion of the opening of the rail and moved.

As described above, according to the present invention, when the door is opened, the lock member provided on the slider allows the hook to be locked in the hole of the rail, and when the door is closed, the lock member causes the hook to lock the rail. Since it is prevented from being locked in the hole, there is an effect that the closing operation of the door can be performed quickly and smoothly.
