It may be provided so as to project laterally with 0a.

Next, a method of opening and closing the roof by the opening and closing mechanism in the opening and closing type membrane roof having the above structure will be described. (1) When the openable roofs 12 and 12 are opened In this case, as shown in FIG.
The roof units 46 and 46 of the open / close roofs 12 and 12 provided on both sides of the open / close roofs 12 and 12 are connected at the central portion of the main rail 10 to open the open / close roofs 12 and 12 from the closed state. 12 to 14, the traveling carriage 25, the pushing rod 30, the guide groove group 32 and the like are omitted.

First, after disconnecting the roof units 46, 46 from each other, the driving carriage of the roof unit 46 is driven toward the end of the main rail 10,
By pushing the roof units 11 ... With the roof unit 46, these roof units 11 ... are moved to the end side of the main rail 10. At this time, since the main rail 10 has a downward slope, the roof units 11 ... Also move due to their own weight, but when it is necessary to adjust the moving speed, the driving force in the opposite direction is applied to the driving carriage. Put on.

When the roof units 11 move, a compressive force acts on the connecting member 27 provided between the traveling carriages 25 supporting the roof units 11 for some reason. And the connecting member 27 is the second hinge portion 2
Even if the connecting member 27 is bent from 9, the connecting member 27 is held in a state in which it is bent slightly downward from the second hinge portion 29 so as to be stretched, so that the connecting member 27 is not folded and therefore the roof unit 11 does not fold and moves stably on the main rail 10. Also,
When the respective roof units 11 ...
.. roll on the inner side surfaces of the side wall 13a and the wall portion 26 that face each other, so that the roof units 11 ... Are prevented from rolling and move smoothly.

Then, each roof unit 11 is mounted on the traveling carriage 2
When moving by 5 to approach the end of the main rail 10, the leading (first) push rod 30 provided on the connecting member 27 of the leading (first) roof unit 11 in the moving direction.
Reaches the guide groove group 32 and moves above the guide groove group 32 while floating in the air. When the first push rod 30 reaches the first guide groove 32b located at the head of the guide groove group 32, the wheel 31 of the push rod 30 rolls in the guide groove 32b as shown in FIG. By doing so, the pushing rod 30 moves in the first guide groove 32b. Then, when the first pushing rod 30 moves in the first guide groove 32b and reaches the end of the guide groove 32b, as shown in FIG. 9, on the inclined surface 33 formed at the end. While moving, the second hinge portion 29 of the connecting member 27 of the first roof unit 11 is pushed upward.

Then, the connecting member 27 causes the second hinge portion 2 to move.
It is folded from 9 and the first roof unit 11
When the second traveling carriage supporting the opening / closing frame on the rear side of the first roof unit approaches the first traveling carriage 25 supporting the opening / closing frame 16 on the front side of the vehicle, the connecting member 27 is folded. At the same time, the open / close frames 16, 16 of the first roof unit 11 are folded. When the connecting member 27 is folded, the first push rod 30 moves from the inclined surface 33 to the keel truss 13.
It moves upward, further rises with the rise of the second hinge portion 29, and separates from the keel truss 13.

On the other hand, at the same time as or after the push rod 30 of the first roof unit 11 reaches the first guide groove 32b, the push rod 30 of the next (second) roof unit 11 moves to the above-mentioned 1 Th guide groove 32b
It reaches the next (second) guide groove 32b further rearward and moves along this guide groove 32b, and during this movement,
The second roof unit 11 is folded.

When the push-out rod 30 of the second roof unit 11 reaches the end of the second guide groove 32b, it moves up on the inclined surface 33 formed at this end and rises. Thereby, the second roof unit 1
The second hinge portion 29 of the first connecting member 27 is pushed upward,
The connecting member 27 is bent from the second hinge portion 29, and the opening / closing frame 1 on the front side of the second roof unit 11 is further bent.
When the second traveling carriage 25 supporting the opening / closing frame 16 on the rear side of the second roof unit 11 approaches the second traveling carriage 25 supporting 6 the folding member 27 is folded. At the same time, the open / close frames 16, 16 of the second roof unit 11 are folded.
When the connecting member 27 is folded, the second pushing rod 30 moves from the inclined surface 33 to the first guide groove 32.
b), further rises as the second hinge portion 29 rises, and is separated from the keel truss 13.

Similarly, the pushing rods 30 of the third, fourth ... Roof units 11 ... are the third, fourth ...
By moving the guide grooves 32b ... Of the connecting members 27, the second hinge portions 29 of the respective connecting members 27 are pushed upward to be folded, and the roof units 11 are sequentially folded from the top, so that the main rails 10 are The roof units 11 ... Are moved toward the end side and are housed in the roof housing part 45 provided at the end part of the main rail 10 (see FIG. 13). The roof unit 46 is stored in the roof storage portion 45 as it is.

When the opening / closing roof is opened by the roof unit 11 as described above, when each roof unit 11 travels on the main rail 10, a compressive force acts on the opening / closing frames 16, 16 of the roof unit 11. Also, it is possible to stably run the open / close frames 16 and 16 with the frames open. In addition, since each roof unit 11 that is sequentially moved to the end side of the main rail 10 can be folded when the roof unit 11 in front of it is stopped at the end side of the main rail 10, that is, When the roof unit 11 moves on the main rail 10,
Since the vehicle runs in an open and stable state and is sequentially folded on the end side of the main rail 10, the roof unit 11 can be stably run and the roof storage section 4 on the end side of the main rail 10 can be run.
5 can be stored in a stable state.

Further, since each roof unit 11 has an independent structure in which the film material 15 is stretched on itself, the opening / closing frames 16, 16 of a certain roof unit 11 cannot be opened / closed for some reason. However, since the other roof units 11 function normally, opening / closing at that time does not become impossible. Further, since each roof unit 11 has the membrane material 15 stretched on itself, the membrane material 15 is not fluttered in any state of opening and closing the roof, and the membrane material 15 is stretched. The open / close frames 16 and 16 are connecting members 17.
By extending, it becomes a stable triangular truss,
When each roof unit 11 travels on the main rail 10, it is always in a structurally stable state. Therefore, the roof can be opened and closed smoothly even if the roof is opened and closed by the wind or the like.

Further, when each roof unit 11 travels on the main rail 10, it is always in a structurally stable state. Therefore, even if the roof unit 11 is stopped in the middle of the main rail 10, it is structurally stable. ing. Therefore, the roof unit 11 can be stopped in the middle of the main rail 10, whereby the opening area of the roof can be easily adjusted. In addition, the film material 15 is the open / close frame 16,1.
Since it is stretched in advance in FIG. 6, there is no need for a force to bend the membrane material 15 itself, and therefore power for traveling the roof unit 11 on the main rail, that is, driving of the drive carriage provided in the leading roof unit 46. The roof can be opened and closed only by force. Further, since the leading roof unit 46 that sequentially moves the roof units 11 on the main rail 10 has substantially the same shape as that of the roof units 11 and has a rigid structure, the leading roof unit 46 is driven by a drive carriage. As a result, the roof units 11 ... Can be stably moved along the main rail 10, and the roof can be opened and closed more smoothly.

(2) When closing the open / close roofs 12 and 12, first, the open / close roofs 12 stored in the respective roof storage portions 45.
Driving the roof unit 46 of the main rail 1
It is moved by a predetermined pitch toward the center of 0. Then, the opening / closing frame 1 of the next roof unit 11 in the folded state
One side of 6, 16 is pulled by the roof unit 46, whereby the open / close frames 16, 16 are opened, and the folded connecting material 17 is extended straight to provide a structurally stable cross-sectional triangular shape. One shaped roof unit 11 is formed. In addition, the connecting material 17,
When a pulling force for straightening the folded state from the folded state is applied, the connecting member 17 causes the second hinge portion 2 to move.
9 is bent so that it is located slightly above and bears the tensile force in this state.

Then, by moving the roof unit 46 further by a predetermined pitch, the next roof unit 11 is further pulled out from the roof storage portion 45 in the same manner as described above, and the opening / closing frames 16 and 16 are opened to cross-section. By sequentially repeating the process of forming the roof unit 11 having a triangular shape, as shown in FIG. 14, each roof unit 11 of the open / close roof 12 folded and stored in the roof storage portion 45 is viewed in cross section. Pull out while forming in a triangular shape. Further, when opening each roof unit 11, the second hinge portion 2 is extended as the connecting member 27 extends.
9 descends, the extruding rod 30 descends, the extruding rod 30 descends to the guide groove group 32, and moves in the guide groove group 32. Finally, each openable roof 1
By connecting the roof units 46, 46 of 2, 12 at the central portion of the main rail 10, the openable roof 12, 1
Close 2 completely.

If the opening / closing roof is closed by the roof units 11 ... Also, it is possible to stably run the open / close frames 16 and 16 with the frames open.
