In FIG. 1, reference numeral 1 denotes a roof of a vehicle or the like, 2 denotes a roof opening, and panels 3 capable of closing the opening 2 are provided on both left and right sides of the opening 2 so as to extend in the front-rear direction. The guide rails 4 move back and forth.

That is, the guide rail 4 has a shoe 5 for supporting the front portion of the panel 3 and a push-pull cable or the like (not shown).
Accordingly, a driving member 6 driven back and forth, and a link member 7 that moves back and forth together with the panel 3 are respectively held movably back and forth.

A bracket 8 is provided on the panel 3, and the bracket 8 is formed with a cam groove 9 having a “F” shape.
The drive member 6 has a pin that engages with the cam groove 9.
Ten are provided. Therefore, the pin in the cam groove 9
The front and rear movement of the panel 10 causes the rear end of the panel 3 to move up and down with respect to the roof 1.
Is configured.

The rear end of the link member 7 is held by the guide rail 4 as a swing base 18 so as to be able to move back and forth. Since the swing base 18 and the bracket 8 of the panel 3 are connected by the connecting link 17, the link member 7 can be interlocked with the forward and backward movement of the panel 3.

As shown in FIG. 2, the front end of the link member 7 is provided with an upward engaging portion 13 (first engaging portion) and a downward engaging portion 15 (second engaging portion). I have.

On the other hand, the guide rail 4 is provided with an engaged portion 12 (engaging concave portion) which can be engaged with the upwardly engaging portion 13 of the link member 7, and the drive member 6 has a downwardly facing link member 7. An engagement recessed portion 14 engageable with the engagement portion 15 is provided, and a relief space A for the upward engagement portion 13 to be separated from the engaged portion 12 is formed. Further, the drive member 6 is provided with a receiving member which can be brought into contact with the downwardly engaging portion 15 behind the engagement concave portion 14 in order to maintain a state in which the upwardly engaging portion 13 is engaged with the engaged portion 12. Department

With the panel 3 closing the roof opening 2,
As shown by a solid line in FIG.
13 engages with the engaged portion 12 of the guide rail 4, and the downwardly engaging portion 15 does not engage with the engaging concave portion 14 of the driving member 6, but comes into contact with the receiving portion 16.

Then, the driving member 6 is moved rearward from this state,
When the downward engaging portion 15 comes into engagement with the engaging concave portion 14,
As shown by a two-dot chain line in FIG. 2, the upwardly engaging portion 13 is disengaged from the engaged portion 12 due to the downward swing of the link member 7, whereby the link member 7 can be moved back and forth together with the drive member 6. become.

In the opening / closing drive device having such a configuration, the panel 3
Is in the closed position, as described above, the link member 7
Since the upwardly engaging portion 13 is engaged with the engaged portion 12 of the guide rail 4, the panel 3 is locked and held so as not to move back and forth.

When the driving member 6 is moved backward from this state, the rear side of the panel 3 is tilted up (up) from the position indicated by the two-dot chain line in FIG. .

After that, when the driving member 6 is further moved backward, the downward engaging portion 15 of the link member 7 and the receiving portion of the driving member 6 are received.
The contact with the engagement recesses 14 is allowed, and the engagement with the downward engagement portions 15 is allowed.

Therefore, the link member 7 swings downward and the upward engagement portion
Since the drive member 6 and the link member 7 are disengaged from the engaged portion 12 from 13, the drive member 6 and the link member 7 move rearward together along the guide rail 4,
The panel 3 is opened (moved backward).

Needless to say, if the driving member 6 is thereafter moved and driven in the opposite direction, the operation opposite to the above can be obtained.

For reference, instead of providing the receiving portion 16 in the driving member 6, it is also possible to adopt a structure as described below to make the structure relatively simple.

That is, in the first reference example shown in FIG. 3, the link member 7 is urged by the spring 20 so that the upward engaging portion 13 slides on the upper surface side of the guide rail 4. Therefore, the spring 20 has the same operation as the receiving portion 16.

In the second reference example shown in FIGS. 4 to 7,
Reference numeral 21 denotes a cam plate which is disposed between the driving member 6 and the base 22 of the link member 7 and is provided to be able to move back and forth along the guide rail 4.

The cam plate 21 is formed with an inclined cam portion 24 which can be engaged with the pin 23 of the link member 7 and a holding portion 25 at the rear portion thereof so as to communicate with each other in an "L" shape.

The inclined cam portion 24 is located at a position corresponding to the closing of the panel 3.
When the cam plate 21 moves forward, the engaging portion 13 of the link member 7 is engaged with the engaged portion 12, and when the cam plate 21 moves backward, the engaging portion 13 is disengaged from the engaged portion 12. doing.

The holding portion 25 is for holding the engagement portion 13 irremovably in a state where the engagement portion 13 is engaged with the engaged portion 12, and is substantially horizontal.

The cam plate 21 is pushed by the driving member 6 when the panel 3 is tilted up by the elevating mechanism 11, and moves together rearward. Cam plate 21 and link member 7
A spring 26 is interposed between the base 22 and the base 22 in a resilient manner.
27 and 28 are projections for holding the spring 26, and 33 is a push-pull cable.

In this configuration, when the panel 3 is in the closed position, as shown in FIG. 6, the cam 23 is engaged with the engaging portion 13 of the link member 7 and the engaged portion 12 of the guide rail 4. Plank 21
The engaging portion 13 and the engaged portion 12 are not disengaged even when an external force acts on the panel 3, so that the panel 3 is prevented from moving backward.

When the drive member 6 is moved backward, the cam plate 21 is pushed by the drive member 6 and moves backward together, and the spring 26 is compressed.
At this time, since the pin 23 moves to the inclined cam portion 24, the front end side of the link member 7 is lowered, and the engaging portion 13 is disengaged from the engaged portion 12. Therefore, the panel 3 moves backward.

Such an inclined cam portion 24 and a holding portion 25 are connected to the receiving portion 16.
The same operation as that of the above is achieved. In this configuration, since the relative movement amount between the driving member 6 and the panel 3 can be increased while the length of the driving member 6 is suppressed, the device can be made compact and the moving resistance can be reduced (the opening / closing operation can be smoothly performed). ) Can be achieved.

FIG. 8 shows a third reference example. The upper and lower portions of the second reference example are substantially reversed, and the engaged portion 12 of the guide rail 4 and the engaging portion 13 of the link member 7 are provided on the lower side. The inclined cam portion 24 of the plate 21 is also reversely inclined. The connecting link 17 is pivotally attached to the front end of the link member 7.

The drive member 6 and the link member 7 are provided side by side in the guide rail 4, and the drive member 6 is provided with an engagement pin 30 movable in a groove 29 in which the link member 7 is provided.

The cam plate 21 is provided so as to sandwich the rear end portion side of the link member 7, and has openings 31 and 32 which coincide with each other. A spring 26 is held in the openings 31 and 32 by protrusions 27 and 28.

In the third embodiment, other functions and effects are substantially the same as those of the second embodiment except that the engaging pin 30 engages with the cam plate 21 when the driving member 6 moves backward.

Of course, the inclined cam portion 24 and the holding portion 25 perform the same operation as the receiving portion 16.

(Effects of the Invention) According to the present invention, when the drive member 6 is moved back and forth within the operation area of the elevating mechanism 11, the engagement portion 13 is backed up by the receiving portion 16 with which the link member 7 abuts. By engaging the engaging portion 13 of the link member 7 with the engaged portion 12 provided on the guide rail 4 side, the panel 3 can be prevented from moving back and forth during the tilt-up operation of the panel 3 with a simple structure. And the driving member 6 is moved up and down
When the driving member 6 is out of the operation area of FIG.
The engaging portion 13 of the link member 7 is disengaged from the engaged portion 12 on the guide rail 4 side by fitting the engaging portion 13 of the link member 7 into the engaging member 14 or by providing a relief space A. The member 7 and the panel 3 can be moved back and forth in conjunction with the drive member 6, and thus the switching between the back and forth movement and the tilt operation of the panel can be performed, so that the structure can be simplified. This makes it possible to reduce the size and cost of the sunroof as a whole, reduce the possibility of failure, and reduce the occurrence of malfunctions.
