Description

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

(Prior art, problem to be solved by the invention) In a retractable membrane roof device in which a membrane roof is opened and closed over a ceiling opening, it is necessary for the membrane roof to move smoothly relative to the roof frame when opening and closing. It is.

If the membrane roof does not move smoothly, increase the capacity of the membrane roof opening/closing motor, or increase the strength of the power transmission means for transmitting the power of the membrane roof opening/closing motor to the membrane roof or the membrane roof itself. This creates a problem of high costs.

This is especially true when the length and width of the membrane roof are large.

The present invention has been devised in view of the above circumstances, and an object of the present invention is to enable smooth movement of the membrane roof when opening and closing, even when the length and width of the membrane roof are large. The present invention provides a membrane roof guide structure for 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 guide structure for a retractable membrane roof device in which a membrane roof 5 is extended to a roof frame 3 so as to be openable and closable. 15, and a number of carts 21 that are attached to the membrane roof 5, engage with the guide frame 15, and run along the guide frame I5.

(Function) The membrane roof 5 can be moved smoothly along the guide frame 15. Therefore, the capacity of the power source for the hoisting device 7 and the removal device 11 is small enough. High strength is not required for the power transmission means for transmitting power to the membrane roof 5 itself or for the membrane roof 5 itself, and the cost of the retractable membrane roof device 1 can be reduced.

In addition, when the width and length of the membrane roof 5 are large, the membrane roof 5
If a plurality of guide frames 15 are provided at intervals in the width direction, and a trolley 21 is provided corresponding to each guide frame 15, the membrane roof 5 can be moved smoothly.
