A guide plate 61 is provided for rolling guidance. The upper end of the guide plate 61 has a horizontal surface and the rear end has a vertical surface. When the front slide panel is in the closed position shown in FIG. 20
are confronted.

Next, the operation of the above device is explained in Figs. 1 and 3.
This will be explained based on the diagram. Figures 1a and 3a
indicates the slide panel closed state. In this closed state, the stopper pin 15 of the front assembly A is locked in the notch 58 of the guide rail 8, and the first traveling body 9
The movement of the front slide panel 4 is restricted, and the guide roller 20 provided at the front end of the front slide panel support 12 contacts the vertical surface of the guide plate 61 to hold the front slide panel 4 in the lowered position. Further, the stopper pin 34 of the rear assembly B is locked in the notch 59 of the guide rail 8 to restrict the movement of the second traveling body 28, and the third traveling body 29 is also at the rear end position of the guide rail 8. , the first link 30 and the second link 3
1, the rear slide panel 5 is also in the lowered position. At this time, the rear slide panel support 3
A guide roller 55 provided at the front end of the slide panel 2 is held in a roller receiving recess 27 of the front slide panel support 12. In this state, the front slide panel 4 and the rear slide panel 5 are located on the same plane as the roof surface 1 and close the roof surface opening 2.

In this closed state, when the operation cable 57 is pulled forward via a cable drive mechanism (not shown) by an operation from the indoor side, the third traveling body 29
moves forward, and on the other hand, the movement of the second traveling body 28 is restricted by locking the stopper pin 34 in the notch 59, so that the first link 30 and the second link 31
Due to the cooperative action, the rear end portion of the rear slide panel 5 is lifted upward via the rear slide panel support 32.

In this way, as shown in FIGS. 1b and 3b, when the third traveling body 29 moves to the position where the stopper pin receiving recess 40 corresponds to the notch 59, the stopper pin provided on the third traveling body 29 is lifted. The guide pin 49b of the guide member 49 rides on the chevron-shaped guide piece 50 provided on the guide rail 8 side and rises, lifts the stopper pin 34 to remove it from the notch 59, and locks it in the stopper pin receiving recess 40 instead. As a result, the second traveling body 28
The movement restriction of is lifted, and after this, the second traveling body 28 and the third traveling body 29 are connected to each other by the leaf spring 34 so as to maintain a certain distance, that is, the rear end of the rear slide panel 5 is at a predetermined height. It is held in a state where it is pulled forward. At this time, the front end of the front slide panel support 32 is connected to the guide roll 55.
is rolled and guided on the roller travel guide piece 26 of the rear slide panel support 12. In addition,
Immediately after the stopper pin 34 passes through the notch 59, the guide pin 49b of the stopper pin lifting guide member 49 descends over the chevron-shaped guide piece 50, so that lifting and holding of the stopper pin 34 by the guide member 49 is released.
Instead of this guide member 49, the upper end surface of the guide rail 8 continues to restrict the descent of the stopper pin 34, so the stopper pin 34 continues to be locked in the stopper pin receiving recess 40, and the second traveling body 28 and the third traveling body 29 are kept at a specified distance.

The rear slide panel 5 is
As shown in FIG. The restoring force causes the stopper pin 34 to move into the stopper pin receiving recess 40.
The movement of the second traveling body 28 is restricted again, and the leaf spring 3
3, the connection between the second traveling body 28 and the third traveling body 29 is released. Therefore, after this, when the operating cable 57 is pulled, only the third traveling body 29 moves forward, and due to the cooperative action of the first link 30 and the second link 31, it moves through the rear slide panel support 32. Then, the rear end portion of the rear slide panel 5 is further lifted upward. Further, as the third traveling body 29 moves forward, the stopper pin 34 moves relatively toward the back of the stopper pin guide slit 38 (FIG. 6).

The stopper pin 34 is inserted into the stopper pin guide slit 38 as shown in FIGS. 1d and 3d.
(Fig. 6) When you move relative to the depths, slit 3
The stopper pin 34 is lifted by a tapered portion (not shown) provided at the back of the stopper pin 34 and removed from the notch 60, and is instead locked in the stopper pin receiving recess 41. As a result, the movement restriction of the second traveling body 28 is released again, and the second traveling body 28 and the third traveling body 29 are connected by the leaf spring 33.
On the other hand, the stopper pin 15 of the first traveling body 9 fits into the notch 39 provided at the tip of the lever 37 of the third traveling body 29, and the stopper pin 15 follows the tapered surface on the rear end side of the notch 39. It is pushed up and removed from the notch 58. As a result, the movement restriction of the first traveling body 9 is released, and the first traveling body 9 is connected to the third traveling body 29 via the lever 29. Therefore, the first traveling body 9, the second traveling body 28, and the third traveling body 29 are then pulled forward while keeping the distance between them constant.

Immediately after the first traveling body 9 starts moving forward, the guide roller 20 provided at the front end of the front slide panel support 12 is in contact with the vertical surface on the rear end side of the guide plate 61. , rising along its vertical plane. As a result, the front link 10 and the rear link 11 are raised, and the front slide panel 4 is lifted upward together with the rear slide panel 5 placed overlappingly above the front slide panel 4 via the front slide panel support 12. thus,
When the guide roller 20 passes through the vertical surface of the guide plate 61 and moves to the upper end surface of the guide plate 61, the front slide panel 4 moves forward together with the rear slide panel 5 superimposed thereon while maintaining its posture. go. and Figures 1e and 3e
As shown in FIG.
When you move it to a position where it is completely superimposed on the top,
The cable drive mechanism of the operating cable 57 stops. In this way, the roof opening 2 is fully opened.

Closing of the slide panel is performed by moving the operating cable 57 rearward using a cable drive mechanism (not shown). The closing operation performed at this time is the opposite of the above-mentioned opening operation, so a description thereof will be omitted.

As described above, according to this sliding roof device, the slide panel 3 is composed of two divided panels, the front slide panel 4 and the rear slide panel 5, and the front slide panel 4 and the rear slide panel 5 are separated from each other on the roof surface. Since the roof surface opening 2 is formed so as to be overlapped on top of each other, the area of the opening 2 can be taken up to two-thirds of the area of the roof surface, thereby widening the roof surface opening 2. be able to. Further, since both the front slide panel 4 and the rear slide panel 5 can be opened and closed using a single operation cable 57, the number of cable drive mechanisms such as cable motors can be reduced, and costs can also be reduced.

(Effects of the invention) As described above, according to the sliding roof device of this invention, by dividing the sliding panel into two, a wider roof surface opening can be obtained, and the sliding roof device can be slid with a single operation cable. Since the panel can be opened and closed, the cable drive mechanism can be simplified and costs can be reduced.
