Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a membrane roof removal device for a retractable membrane roof device that opens and closes a ceiling opening.

(Prior art) In a retractable membrane roof device in which a membrane roof is opened and closed over a ceiling opening, when opening the ceiling opening, the membrane roof is generally rolled up using a winding drum, and the membrane roof is stretched over the ceiling opening. This is done by moving the part in the direction of opening.

(Problem to be solved by the invention) However, when the width of the membrane roof increases or the length of the membrane roof increases, this method requires an increase in the size of the winding drum and the need to rotate the winding drum. The motor for this purpose also becomes larger, and the structure on the winding side becomes larger and more complex, leading to problems such as increased costs.

The present invention has been devised in view of the above circumstances, and an object of the present invention is to easily open a ceiling opening with a compact and simple structure even when the width and length of the membrane roof are large. To provide a membrane roof removal device capable of reducing the cost of a retractable membrane roof device.

(Means for Solving the Problems) The present invention for achieving the above object will be described with reference to drawings corresponding to embodiments.

The present invention is a membrane roof removal device for a retractable membrane roof device in which a membrane roof 5 is extended to a roof frame 3 in an openable and closable manner,
A large number of locking portions 213 are arranged on the membrane roof 5 in a row along the opening/closing direction of the membrane roof 5, and a plurality of locking portions 213 are provided on one end side of the roof frame 3 in the opening/closing direction and lock with the locking portions 213. It is characterized in that it is comprised of a pulling mechanism 11A that sequentially draws the locking portion 213 toward the end of the roof frame 3.

(Operation) The membrane roof 5 is moved to the end side of the roof frame 3 by sequentially pulling the locking parts 213 by the pulling mechanism 11A, and the ceiling opening is opened.

Even if the width and length of the membrane roof 5 are large, the locking portion 2
13 and a plurality of pulling mechanisms 11A are provided at intervals in the width direction of the membrane roof 5, the membrane roof 5 can be easily moved.
Compared to the case where the membrane roof 5 is removed using a winding drum, the structure can be made more compact and simple, and costs can be reduced.

(Example) Embodiments of the present invention will be described below with reference to the accompanying drawings.

Frame members 17 of the two guide frames 15
As shown in FIG. 1, pulleys 27 are rotatably disposed between the vertical walls 17B at intervals in the longitudinal direction.

The membrane roof 5 is stretched over the roof frame 3 by winding up the wire 25 with the winding device 7 . Further, when the membrane roof 5 is pulled up by the removal device 11 and the ceiling opening is opened, the wire 25 is guided by the pulley 27 and is passed from the winding device 7 side to the removal device 11 side.

FIG. 7 shows a side view of the hoisting device 7.

The winding device 7 includes a winding section 7A provided for each frame 3A, 3B.

Each winding section 7A is composed of a motor 31 and a pulley 33 attached to the output shaft of the motor 31, and one end of the wire 25 is connected to the pulley 33 via a guide pulley 35.
The wire 25 is configured to be wound up by driving the motor 31.

To lock one end of the membrane roof 5 to the ground, raise the claw body 39A, lock the tip of the claw body 39A to the locking rod 37, and then swing the claw piece 39B downward as shown by the arrow. This is done by moving the claw piece 39B and locking it to the locking rod 37.

The removal device 11 is composed of a pulling mechanism 11A provided for each frame 3A, 3E.

As shown in FIG. 4, no boob is 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 the 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 side of the guide frame 15.
and a chain 49 whose negative side is disposed on the chain guide 43 and hung between both sprockets 45 and 47, and a chain 49 which is attached to the chain 49 at a distance and can be engaged with the rod 213 of the truck 21. Hook 51 (see Figure 5)
Equipped with.

Rollers 4 are attached to the pivot points of the links that make up the chain 49.
9A is attached and configured to roll on the chain guide 43.

A sprocket 55 attached to the output shaft of a motor 53 is connected to the drive 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 engages with the rod 213 to move the trolley 2.
1 to the other end side of the guide frame 15, and the membrane roof 5
Move the to open the ceiling opening. Therefore, in this embodiment, the rods 213 correspond to locking portions arranged in rows along the opening/closing direction of the membrane roof 5.

A square steel pipe 61 is attached to the cart 21 on the other end side of the membrane roof 5 as shown in FIG. 12, and wires 63 are installed at intervals on the square steel pipe 61 as shown in FIG. is attached.

The tension adjustment device 13 includes a large number of rotatable pulleys 65 installed on the ground side, and each wire 63 is routed to the frame 3A or 3B side as shown in FIG. 3 via the pulleys 65. The tension of the membrane roof 5 is adjusted by being wound up or unwound by a winding drum 67 disposed near the frame 3A or 3B.

Since this embodiment is configured as described above, when the membrane roof 5 is removed, the chain 49 and the hook 51 are moved by the drive of the motor 53, and the hook 51 engages with the rod 213 to move the cart 21 to the guide frame 15. It is pulled toward the other end, and the membrane roof 5 is moved to open the ceiling opening.

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

Furthermore, even if the width of the membrane roof 5 is large, as in the embodiment (if there are multiple pulling mechanisms 11A in the width direction of the membrane roof 5), Even if it is large, the membrane roof 5 can be easily moved.

In the embodiment, the membrane roofs 5 pulled together by the pulling mechanism 11A are stacked one on top of the other. However, after being pulled together, the membrane roofs 5 may be wound up on a drum. In this case, the membrane roofs 5 are pulled together by the pulling mechanism 11A. Since the drum is pulled together, a motor with a small capacity is sufficient to rotate the drum.

Further, when the membrane roof 5 is expanded and stretched on the roof frame 3 from the state where the membrane roof 5 is removed by the pulling mechanism 11A, the motor 53 of the pulling mechanism 11A may be reversed, or the motor 53 of the pulling mechanism 11A may be rotated in the reverse direction, or a clutch mechanism or the like may be used. It is also possible to disconnect the motor 53 and the chain 49 side and let the chain 49 spin idly.

(Effects of the Invention) As is clear from the above description, according to the present invention, the membrane roof is moved to the end side of the roof frame by sequentially pulling the locking portions using the pulling mechanism, thereby opening the ceiling opening. Therefore, even if the width and length of the membrane roof are large, the ceiling opening can be easily opened due to the compact and simple structure, and the cost of the retractable membrane roof device can be reduced.
