DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a panel type shutter attached to an opening of a building, between vertically adjacent panel bodies and both ends of each panel body, and a guide for vertically moving the both ends. The present invention relates to an airtight structure of a panel shutter that seals a gap formed between a rail and a rail.

[Prior art and its problems]

Conventionally, as for the airtightness of a panel type shutter, as shown in FIG. 5, a pair of guide rails 8, 8 for guiding the left and right ends of each panel body 3 sandwiches each panel body 3 and face each other along the longitudinal direction. Airtight pieces 20, 20 are provided, and the airtight pieces 20, 20 are slidably contacted from both sides of each panel body 3 to guide rails 8, 8,
I try to seal the gap between and.

However, in this case, each time the panel shutter is opened and closed, the airtight piece 20 slidingly contacting the surface of each panel body 3 due to the elevation of each panel body 3 is worn in a short period of time and lacks durability, and each panel is There is a problem that the airtight piece 20 is rubbed on the surface of the body 3 to generate dirt, and further, the airtight piece 20 simply slides on the surface of the panel body 3, so that the airtightness and sound insulation are not sufficient. there were. Further, between the panel bodies 3 which are vertically adjacent to each other, uneven step portions are provided at the upper and lower ends of each panel body 3, and when the step bodies are closed, the gaps are closed by fitting the step portions in a superposed manner. The airtightness and sound insulation between these adjacent panel bodies 3 were not sufficient.

[Means for solving problems]

In view of the above situation, the present invention was devised with the object of providing an airtight structure of a panel type shutter that can eliminate these drawbacks, and both ends are inserted into guide rails to be guided up and down. , A plurality of panel bodies that are connected in a chain at predetermined intervals in the vertical direction are arranged so that the upper edge of the preceding panel body and the lower edge of the succeeding panel body are brought into contact with each other to sequentially perform the closing operation. In the panel-type shutter, in each of the panel bodies, an airtight body made of a soft string-shaped hollow body in which a fluid is sealed is disposed in communication with the lower end edge of the panel body and the left and right end edges over the entire length,
The forced movement of the fluid by the crushing of the airtight body located at the lower end edge of the panel body due to the closing operation causes the airtight body located at the both end edges of the panel body to bulge toward the inner wall of the guide rail, and the panel body It is characterized in that it is configured to seal the gaps between both ends and the guide rails and between adjacent panel bodies. With this configuration, the present invention seals the gap between vertically adjacent panel bodies and also seals the gap between each panel body and the guide rails that guide the both ends up and down to achieve complete airtightness and sound insulation. It provides the airtight structure of the panel type shutter that can obtain the property, and at the same time, the airtight piece that slides on the surface of each panel body is worn or the airtight piece is rubbed against the surface of each panel body as in the past. It solves the problem of stains.

〔Example〕

Next, an embodiment of the present invention will be described in detail with reference to the drawings. In the drawings, reference numeral 1 denotes a panel-type shutter installed in an opening of a building, and the panel-type shutter 1
The shutter curtain 2 that constitutes the guide roller 4 is provided on the upper side of both left and right edges of the plurality of panel bodies 3 respectively.
A connecting chain 6 is pivotally connected to the support shaft 5 so that the panel bodies 3 are arranged in a continuous manner with a predetermined space between the adjacent chain bodies. Both ends of the guide roller 4 and the panel body 3 are guided by the guide rails 8 provided upright on the left and right sides of the opening so as to move up and down. The drive sprocket 9 is attached to the upper portion by the chain winding operation. The panel bodies 3 are accommodated in parallel in the shutter case 10 provided. On the contrary, when the shutter curtain 2 is lowered by the unwinding operation of the drive sprocket 9, the panel body 3 transferred from the shutter case 10 is guided by the guide rail 8 and sequentially descends. But,
When there is a predetermined space between the adjacent panel bodies 3, the panel body 3a descends so that the panel body 3a provided at the lowermost end of the shutter curtain 2 on the floor of the opening comes into contact with the ground and stops. 3b descends and stops until it comes into contact with the lowermost panel body 3a. In this way, the intermediate panel body 3b sequentially closes the opening, and the uppermost panel body 3b is closed.
When 3c comes into contact with the adjacent intermediate panel body 3b, it is transformed into a fully closed state in which all the openings are closed, and these have a conventional configuration. In the present invention, as shown in FIGS. 2 to 4, the shutter curtain 2
The airtight body 7 is arranged so as to be in communication with the lower end edge of each panel body 3 and the both end edges of the panel body 3 over the entire length. The airtight body 7 is formed of a sealed bag-like body in which both ends of a cord-shaped hollow body made of a soft material such as rubber or vinyl chloride are sealed. As shown in FIG. 3, its side wall is formed in a bellows shape in a sectional view so as to be expandable and contractible, and a fluid 11 such as air or water is enclosed in the airtight body 7. Fluid 11
When the airtight body horizontal portion 7a located at the lower end edge of each panel body 3 is crushed, the airtight body vertical portions 7b arranged in a standing shape along both left and right edges of the panel body 3 flow along with the crushing. body
Swelled by forced movement of 11 and left and right guide rails 8,8
An appropriate amount is enclosed so as to contact the inner wall surface 8a.

The panel type shutter 1 configured in this manner is used to unwind the drive sprocket 9 and the shutter curtain 2
When the lowermost panel body 3a descends, the horizontal hermetic body 7a attached to the lower edge of the lowermost panel body 3a receives the weight of the panel body 3a and is crushed. The fluid 11 in the airtight body horizontal portion 7a is directed toward the airtight body vertical portion 7b provided in a standing shape along the left and right edges of the panel body 3a which is in communication with the airtight body horizontal portion 7a. Although it is forced to move, since the left and right ends of the airtight body 7 are sealed to form a sealed bag-like body, the fluid 11 fills the airtight body vertical portion 7b and guides the airtight body vertical portion 7b. The rail 8 bulges toward the inner wall side and contacts the inner wall 8a. Next, the airtight body horizontal portion 7a arranged on the lower end edge of the intermediate panel body 3b adjacent immediately above the lowermost end panel body 3a is crushed by being pressed against the upper end edge of the lowermost end panel body 3a. By the action similar to that of the airtight body, the airtight body vertical portion 7b of the intermediate panel body 3b is brought into contact with the side wall 8a of the guide rail 8, and the adjacent panel bodies 3 are sequentially similarly processed so that the uppermost end panel body 3c is directly below the intermediate panel body. In the state where the opening is in a fully closed state by abutting on the upper edge of 3b, the airtight body horizontal portion 7a is provided between each panel body 3, and the gap between each panel body 3 and the guide rail 8 is the airtight body vertical portion 7b. Will be completely sealed. On the contrary, when the panel bodies 3 constituting the shutter curtain 2 are moved upward to open the openings, the airtight body horizontal portion arranged on the lower end edge of the uppermost end panel body 3c as the uppermost end panel body 3c rises. Since 7a is released from being crushed by the self-weight of the panel body 3c, the fluid 11 filled in the airtight body vertical portions 7b at both edges of the panel body 3c when the shutter curtain 2 is fully closed is the airtight body. The airtight body vertical portion 7b moves to the horizontal portion 7a side, and therefore the airtight body vertical portion 7b relaxes to both end sides of the panel body 3c, the airtight body vertical portion 7b and the guide rail 8 are separated from each other, and the uppermost panel body 3c smoothly rises. You can take action. The adjacent intermediate panel body 3b also repeats the same operation in sequence, and the shutter curtain 2 ascends without resistance and the opening is fully opened.

[Effect of device]

As described above, the airtight structure of the panel shutter according to the present invention is such that when the shutter curtain is opened and closed, the left and right guide rails and the airtight body are separated from each other, and each panel body moves up and down, and each panel body when closed is closed. The vertical part of the airtight body placed on the left and right edges of each panel body bulges under its own weight when it stops and contacts the inner wall surface of the left and right guide rails, so that the surface of each panel body is always airtight. Since the pieces do not come into sliding contact with each other, the durability of the airtight body is remarkably improved, and the problem that the airtight pieces are rubbed against the surface of each panel body to cause stains can be completely eliminated.

Moreover, since the gap between both ends of each panel body and the guide rail can be sealed, and the gap between each panel body can be sealed, there is an effect of excellent airtightness and sound insulation.
