2. Description of the Related Art Conventionally, as disclosed in Japanese Utility Model Laid-Open No. 62-16021, a roof panel provided with an openable and closable T-bar roof has been known. This T-bar roof can be opened and closed by an opening and closing device. Has become.

An outline of the opening / closing device is shown in FIG. 11, in which a cable 101 which serves as a traction means and a slider 1 which slides along a guide rail 103 by the cable 101 are provided.
05 and a link 109 that opens and closes the T-bar roof 107 when the slider 105 slides.

[0004]

As described above, in the opening / closing device, the upward force F is obtained by the sliding movement of the slider 105 in the arrow direction, and the T-bar roof 1
A rise of 07 takes place. The upward force F at this time is determined by the height H to the connecting pin 111 that connects the link 109 and the T-bar roof 107.
When the height of the slider 105 is the same as that of the slider 105, the upward force becomes zero, and if the height H to the coupling pin 111 is high, the upward force F can be obtained with a small operating force. On the other hand, the height of the opening / closing device is high and it is difficult to reduce the thickness. In this case, in consideration of the thickness reduction, the position of the coupling pin 111 may be lowered and the slider 105 may be aligned to the height, but a new operation such as a strong operating force for pressing the slider 105 is introduced.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an opening / closing device for an opening / closing body which requires a light operating force and can be made thin.

[0006]

In order to achieve the above-mentioned object, the present invention provides a first link member to which an opening / closing member is attached, and a rotatable pin via a coupling pin at a substantially intermediate portion of the first link member. One of the base ends of the pivotally supported second link member is pivotally attached to a guide member having a rail portion, and the other base end portion is slidable along the rail portion of the guide member by a pulling means. An actuating posture in which the first and second link members stand upright when the slidable base end portion is pivotally supported by the mover and approaches the other pivotally attached base end portion, and the slidable base end portion. The opening and closing device is configured so that the first and second link members can be switched to a storage posture in which the first and second link members lie down along the guide member when the first and second link members are separated from the proximal end portion.
The link member is provided with a coupling pin guide groove for guiding the coupling pin, an engagement pin provided on the second link member, and a detachable engagement pin guide groove that is disengaged during standing up. The pin guide groove includes a first guide region for restricting vertical movements of the coupling pin and the engaging pin when the first and second link members are stored, and a base end portion to which a slidable base end portion is pivotally attached. And a second guide region that allows the first and second link members to stand up by sliding the coupling pin and the engagement pin during an initial slide toward. In a preferred embodiment, the base end portion of the second link member is fixedly supported by the guide member, while the base end portion of the first link member is slidable along the rail portion of the guide member by the pulling means. It was pivoted to.

[0007]

According to such an opening / closing device, the slidable base end portion is moved toward or away from the pivotally mounted base end portion so that the first and second link members are laid down and stored. It becomes possible to switch to the working posture. in this case,
When the first and second link members are in the stored posture, the first guide region reliably restricts the vertical movement of the coupling pin and the engagement pin. In addition, the coupling pin and the engaging pin, when the initial sliding of the slidable base end,
Since it is guided by the second guide regions of the coupling pin guide groove and the engagement pin guide groove, the first and second link members in the collapsed state can be erected with a light operating force. Further, since the first and second link members in the stored posture fall down along the guide member, the height can be suppressed to be low, and the opening / closing device can be thinned. Moreover, since the pivotally-attached base end region is disengaged from the rail portion, the cover can be blinded, and the appearance can be improved.

Further, since the base end side of the second link member side close to the load point is a fixed type, the supporting rigidity is improved.

As a result, when the rotary plate 83 rotates about the gear shaft 81, the guide pin 85 reciprocates in the elongated hole 87, and the drive arms 63, 63 reciprocate in the arrow direction.

Further, the drive motor 65 has the gear shaft 81.
The cam plate 89 attached to the switch is turned off by hitting the switch terminals of the first and second detection switches S1 and S2 for fully closing and fully opening, and the forward stroke and the backward stroke of the drive arms 63, 63 are changed. Will be set. The opening / closing device may be implemented in a vehicle other than an automobile.

Next, the operation will be described.

When the side door 7 of the vehicle is opened when getting on and off, the base end portion 19a of the first link member 19 is moved to the base end portion 21a of the second link member 21 by operating a switch (not shown). As they approach each other, the first and second link members 1
9 and 21 stand up. As a result, the roof door 11 can be pivoted outward with the hinge 15 as a fulcrum and opened. Therefore, the roof opening 1 is connected to the door opening 9 of the side door 7 to form a large opening for getting on and off, and an occupant can easily get on and off without hitting his or her head against the roof without bending over. ..

In this case, the first and second link members 19, 2
In the initial operation of the roof door 11 in which the position 1 is in the lying position, the coupling pin 39 and the engagement pin 41 are guided by the second guide region 53 during the initial sliding of the slidable base end portion 19a. The rotational moment M of the second link member 21 at this time is determined by the thrust FA × span L. In this case, since the span L can be secured large by the second guide regions 53, 53, the first operation can be performed with a light operating force. , Second
The link members 19 and 21 are raised.

Next, to close the fully open roof door 11, a switch (not shown) is operated to retract the base end portion 19a of the first link member 19 from the base end portion 21a of the second link member 21. Thereby, the first and second link members 19, 21
The engaging pins 41 come to engage with each other in the engaging pin guide grooves 49 during the fall and the fall. At this time, if a hand or the like is caught, the engagement pin 41 and the engagement pin guide groove 49 are disengaged from each other, and a large load does not act on the hand. At the same time, the cam plate 89 rotates by a certain amount and strikes the switch terminal of the detection switch S1 for full closing, so that the drive motor 6 stops. It is possible to fully close the intermediate stop state by raising the roof door 11 once and then lowering it again.

On the other hand, the engagement pin 41 engaged in the engagement pin guide groove 49 moves from the second guide region 53 to the first guide region 51, and after the movement is completed, the first and second link members 1
Rotate 9 and 21 downward against the seal reaction force. As a result, the fully closed state of the roof door 11 is obtained. Since the first and second link members 19 and 21 in the fully closed state are in the lying posture II, the height of the opening / closing device 13 can be kept low, and the first and second link members 19 and 21 can be comfortably provided inside the roof panel 5 having a small storage space. Moreover, even if a load acts on the roof door 11,
Since it is received by the second link member 21 on the fixed side near the load point, a reliable support state is secured. Further, by covering a region of the guide member 25 which is separated from the rail portion 27, the mounting portion can be blindfolded.

In this embodiment, the roof door 11 is provided on one side, but it may be provided on both sides. Further, the base end portion 19a of the second link member 19 may be pivotally supported on the slider 29, and the base end portion 19a of the first link member 19 may be rotatably fixedly supported.
