Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a membrane roof winding device for opening and closing a ceiling opening.

(Prior art) Many of the membrane roof devices in which a membrane roof is stretched over the ceiling opening have sag in the membrane roof, and generally, the sag value varies in the longitudinal direction of the membrane roof. It is made up of many pieces cut in three dimensions and pieced together.

In a retractable membrane roof device in which a membrane roof having such a sag is stretched so as to be openable and closable, if the membrane roof is wound up with a winding drum having the same diameter, wrinkles will occur.

Conventionally, therefore, the length of the winding drum is made shorter than the membrane width, and the membrane is wound with a drum of the same diameter while allowing the wider membrane to escape to the outside.

(Problem to be Solved by the Invention) However, in such a method, the tensile force during winding is constantly acting on the membrane roof, so the membrane roof cannot be fully expanded in the membrane width direction during winding. I remain. As a result, when the membrane roof is unfolded, wrinkles remain as marks, resulting in problems such as spoiling the aesthetic appearance.

Furthermore, membrane roofs are often made of glass fibers coated with Teflon, and there is a problem in that the glass fibers break due to wrinkles and the strength of the membrane material decreases.

Furthermore, when an uneven load is applied to the membrane roof due to snow accumulation, etc., when it is rolled up, it is difficult for the membrane roof to escape evenly to the outside at both ends, causing the membrane to shift from side to side. The object of the present invention is to be able to roll up a membrane roof without causing wrinkles or damaging the membrane, and to ensure that the membrane can be rolled up even when unbalanced loads are applied. It is an object of the present invention to provide a winding device for a membrane roof that does not shift.

(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 includes a membrane roof 5 that is extended to a roof frame 3 so as to be openable and closable, and a pair of guide frames 17 that are provided on the roof frame 3 and engage with both sides of the membrane roof 5 to guide the opening and closing movement of the membrane roof 5. and a winding drum 7 for a membrane roof provided at one end side of the pair of guide frames 17. In the retractable membrane roof device, the pair of guide frame portions 17A are located in front of the winding drum 7. is configured to be movable in the width direction of the membrane roof 5, and is provided with interlocking means 19 that connects the pair of guide frame portions 17A and interlocks the pair of guide frame portions 17A in a direction in which the membrane roof 5 is extended; It is characterized in that a biasing means 51 for biasing the guide frame portion 17A outward in the width direction of the membrane roof 5 is provided on one of the pair of guide frame portions 17A or on the interlocking means 19.

(Function) According to the present invention, when the membrane roof 5 is rolled up, the biasing means 51
and a pair of guide frame portions 17 via interlocking means 19.
By moving A, the membrane roof 5 is sufficiently stretched in the width direction and is wound onto the winding drum 7 without wrinkles, thereby preventing damage to the membrane roof 5.

Further, the pair of guide frame portions 17A are connected to the interlocking means 19.
Even if an uneven load acts on the membrane roof 5, the membrane roof 5 can be stretched and rolled up by the same amount at both ends of the membrane roof 5, thereby preventing the membrane roof 5 from shifting.

The biasing means 51 can be composed of a wire 53 connected to one of the pair of guide frame portions 17A or to the interlocking means 19, and a weight 55 suspended by the wire 53. In this way, the biasing means 51 By configuring this, the tension can be easily adjusted.

) etc.

When the drive lever 31 is swung in the direction to tension the membrane roof 5 by the wire 35, the driven lever 33 is also swung in the direction to tension the membrane roof 5. When the wire 35 is moved, the wire 35 is loosened, so that the other guide frame 17A, which engages with the driven lever 33, also swings in the direction of relaxing the membrane roof 5 due to its own weight.

A biasing means 51 for biasing the movable frame 17A outward in the width direction of the membrane roof 5 is connected to one movable frame 17A.

In the embodiment, this biasing means 51 is composed of a wire 53 attached to the movable frame 17A and a weight 55 attached to the end of this wire 53.

is attached.

Next, the effect will be explained.

Both movable frames 17A located at both ends of the membrane roof 5 are always urged outward in the width direction of the membrane roof 5 via the weights 55 and the interlocking means 19, so when the membrane roof 5 is rolled up,
The membrane roof 5 is sufficiently stretched in the width direction even in areas where the sag is large, and is wound onto the winding drum 7 without any wrinkles.

Therefore, since the membrane roof 5 can be rolled up without causing wrinkles, damage to the membrane roof 5 can also be prevented.

Furthermore, even if an uneven load is applied to the membrane roof 5 due to snow accumulation, etc., both movable frames 17A are connected by the interlocking means I9 and move as one, so that the amount of stretching of both ends of the membrane roof 50 in the width direction can be made uniform. , displacement of the membrane roof 5 can be prevented.

Further, in the embodiment, since the biasing means 51 is constructed using the weights 55, the tension can be easily adjusted by, for example, stacking the weights 55 of a constant weight.

In the embodiment, the interlocking means 19 is constructed using the wire 35, but it may also be constructed using a link mechanism using a rod or the like.

Further, the biasing means 51 may be constructed of a spring or the like without using the weight 55.

(Effects of the Invention) As is clear from the above description, according to the present invention, 2. Both guide frame portions located in front of the winding drum are movable in the width direction of the membrane roof, and both guide frame portions are movable in the width direction of the membrane roof.
