Locking of one end side of the membrane roof 5 to the ground side raises the claw body 39A to lock the tip of the claw body 39A with the locking rod 37,
Further, the claw piece 39B is swung downward as indicated by the arrow to move the claw piece 3B.
This is performed by locking 9B to the locking rod 37.

The detaching device 11 includes a pulling mechanism 11A provided for each of the frames 3A and 3B.

As shown in FIG. 4, a pulley is not attached between the vertical walls 17B of the frame member 17 located on the other end side of the guide frame 15, but a chain guide 43 is attached.

As shown in a side view in FIG. 11, each pulling mechanism 11A includes a driving sprocket 45 and a driven sprocket 47 (see FIG. 1) disposed on the other end of the guide frame 15, and one side of the chain guide 43. Both sprockets arranged above
A chain 49 is mounted between the chains 45 and 47, and a hook 51 (see FIG. 5) attached to the chain 49 at a distance and capable of engaging with the rod 213 of the carriage 21.

Rollers 49 are provided at the pivot points of the links constituting the chain 49.
A is attached, and is configured to roll on the chain guide 43.

A sprocket 55 attached to an output shaft of a motor 53 is connected to the driving sprocket 45 via a chain 57.

The chain 49 and the hook 51 are moved by the drive of the motor 53, and the hook 51 is engaged with the rod 213 to draw the carriage 21 to the other end of the guide frame 15, thereby moving the membrane roof 5 to open the ceiling opening. I do. Therefore, in this embodiment, the rods 213 correspond to the locking portions arranged in the opening and closing direction of the membrane roof 5.

A rectangular steel pipe 61 is mounted on the carriage 21 on the other end side of the membrane roof 5 as shown in FIG. 12, and wires 63 as shown in FIG. Is attached.

The tension adjusting device 13 includes a plurality of rotatable pulleys 65 installed on the ground side, and each of the wires 63 is routed to the frame 3A or 3B side via the pulley 65 as shown in FIG.
The tension of the membrane roof 5 is adjusted by being taken up or unwound by a take-up drum 67 arranged near the frame 3A or 3B.

Since the present embodiment is configured as described above, the chain 49 and the hook 51 are driven by the motor 53 when the membrane roof 5 is removed.
The hook 51 engages with the rod 213 to draw the carriage 21 toward the other end of the guide frame 15, and moves the membrane roof 5 to open the ceiling opening.

Since the pulling mechanism 11A has a compact and simple structure provided for each guide frame 15, there is no problem of increasing the size of the openable / closable membrane roof device 1, and the cost of the device can be reduced.

Even when the width of the membrane roof 5 is large, if a plurality of pulling mechanisms 11A are provided in the width direction of the membrane roof 5 as in the embodiment, the width or the length of the membrane roof 5 is large. Even in such a case, the membrane roof 5 can be easily moved.

In the embodiment, the membrane roof 5 pulled by the pulling mechanism 11A is configured to be sequentially stacked. However, after being pulled, the membrane roof 5 may be wound by a drum. In this case, the membrane roof 5 is pulled by the pulling mechanism 11A. A small capacity motor is required to rotate the drum because it is attracted.

Further, when the membrane roof 5 is unfolded on the roof frame 3 from the state in which the membrane roof 5 is removed by the pulling mechanism 11A, the motor 53 of the pulling mechanism 11A may be reversed, or a clutch mechanism or the like may be used. Motor 53 and chain 49
The connection with the side may be released to make the chain 49 idle.

(Effects of the Invention) As is apparent from the above description, according to the present invention, the dolly is sequentially drawn through the locking portion by the pulling mechanism, whereby the membrane roof is moved to the end side of the roof frame, and the ceiling opening is formed. The ceiling opening can be easily opened by a compact and simple structure even when the width and length of the membrane roof are large, and the cost of the openable membrane roof device can be reduced.
