BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening / closing device using a telescopic screen such as a pleated screen or an accordion screen. More specifically, the present invention can be installed horizontally, vertically or horizontally. Further, the present invention relates to a telescopic screen opening / closing device which can be opened and closed from either side of both ends.

[0002]

2. Description of the Related Art A pleated screen device which can be opened and closed from either side of a lateral direction is disclosed in Japanese Utility Model Laid-Open No. 4-1.
No. 01499. In this known device, one end of a cord is fixed to one end of a rail, and a tension cord extending from one end is hung on an upper guide roll of a side plate on one end side of a telescopic screen, lowered, and extended and retracted on a lower guide roll of the same side plate. Progress horizontally in the screen,
Then, it is raised by hanging on the lower guide roll of the side plate on the other end side, is hung on the upper guide roll of the same side plate, is guided to the other end of the rail, and is fixed there. When the telescopic screen 15 of this known device is opened and closed in the vertical or horizontal direction, two rails 11 and 12 are installed symmetrically as shown in FIG.
Both ends of the tension cords 31 and 32 are fixed to the respective rails, and four guide rolls are installed on both side plates 13 and 14, respectively, and the two cords are symmetrically routed.

[0003]

Since the above device has a slider that slides on the rail and is integrated with the side plate, there is no problem when opening and closing horizontally or horizontally, but when opening and closing vertically or diagonally. If the distance between the rails fluctuates, there is a problem that the opening and closing are not smooth, or the opening and closing of the rails are performed by their own weight.

The present invention has been made to solve this problem, and an object of the present invention is to provide a telescopic screen device which can be opened and closed from either side between two rails, Another object of the present invention is to provide a device that does not become heavy in operation and does not open and close under its own weight even when installed so as to open and close in a vertical or oblique direction.

[0005]

In order to achieve the above object, the present invention employs two sliders which slide a side plate on which a telescopic screen is stretched along a rail,
A cylindrical body connecting the sliders, and the cylindrical body is vertically slidably fitted to a connecting portion vertically protruding from the rails of the two sliders, and both ends are fixed to each rail, and an intermediate portion is formed. Is that the other slider of the side plate is pressed against one rail by one tension cord penetrating the telescopic screen, and the one slider of the side plate is pressed against the other rail by the other cord.

[0006]

[Function] Since both side plates of the telescopic screen are always pressed and held by the two rails with a constant elastic force by the tension cord, the telescopic screen is not only horizontally or vertically but also vertically or obliquely vertically. The force required for opening and closing is always constant even if the distance between the two rails that guides the opening and closing of the expandable screen is always constant. The screen does not become heavy or light, and the screen does not open and close by itself.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of the present invention; As shown in FIGS. 1 and 2, the pleated screen device includes two parallel rails 11 and 12 along the upper and lower sides or left and right sides of the opening 10 and two side plates 13 orthogonal to the rails.
14 and a pleated screen 15 stretchably stretched between the two side plates. The two rails 11 and 12 have a shape in which a longitudinal slit 16 is provided at the center of one surface of the square tube, and the slits 16 of the two rails are opposed to each other. Side plate 13,
Reference numeral 14 denotes a slider 17 slidably mounted on each of the two rails 11 and 12 via a slit 16, and two rails 1
A cylinder 20 is provided for connecting the two sliders mounted on 1 and 12. The connecting portion 17a of the slider 17 is orthogonal to the rails 11 and 12 from the slit 16. Both end edges of the pleated screen 15 are fixed to the outer surfaces of the opposed cylindrical bodies 20 of the two side plates 13 and 14. As shown in FIG. 3, each slider 17 has a connecting portion 17a vertically projecting from the slit 16 of the rail 11, and a sliding portion 17c sliding in the rail, and the sliding portion 17c extends along the guide surface 22 of the rail. Slide. The connecting portion 17a of the slider 17 has a vertically extending concave portion in the center, and pulleys 18 and 19 are pivotally mounted in the concave portion. Square tube 20 is slit on the outer surface
The cover 23 is detachably fitted into the slit.

As shown in FIGS. 1 and 2, one end of a tension cord 31 is fastened to one end of a rail 11 via a fastening tool 21, and the tension cord is connected to a rail 11 of a slider 17 at one end of the rail 11. Hang on the pulley 18 on the side from the inside, then hang on the pulley 19 on the screen side of the slider 17 mounted on the rail 12 of the side plate 13, then the slider 17 and the cord holes 17b, 20b of the cylindrical body 20, and then the cord of the pleated screen 15. It penetrates the hole 15a. Next, the slider 17 enters the inside of the slider 17 through the code hole 20b of the cylindrical body 20 of the side plate 14 on the other end side and the code hole 17b of the slider 17, and hangs on the pulley 19 on the screen side from the outside. Hang the rail on the pulley 18 on the rail side of the slider 17 attached to the other end from the inside
Lead to the other end of 11 and tension cord 31 through fastener 21
The other end there. Since the tension cord 31 has elasticity, the slide portions 17c of the two sliders 17 on the rail 12 side on which the tension cord 31 is hung are pressed against the guide surface 22 of the rail 12. On the other hand, one end of the tension cord 32 is fastened to one end of the rail 12 via a fastening tool 21, and the tension cord is hung from the inside on the rail-side pulley 18 of the slider 17 at one end of the rail 12, and then the rail 11 Of the slider 17 on one side of the screen 17 on the screen side, and then pull out from the side plate 13 through the slider 17 and the code holes 17b and 20b of the cylindrical body 18, and then sequentially pass through the code holes 15a of the pleated screen 15, and so on. Then, it is advanced to the side plate 14 on the end side, and then is inserted into the slider 17 on the other end side of the rail 11 from the cylindrical body 20 and the code holes 20b and 17b of the slider 17, where the pulley 19
From the outside, and then from the inside to the pulley 18 on the rail side of the slider 17 on the other end of the rail 12, guide the other end of the tension cord 32 to the other end of the rail 12, and attach it through the fastener 21. To stop. Since the tension cord 32 has elasticity, the slide portions 17c of the two sliders 17 on the rail 11 side on which the tension cord 32 is hung are pressed against the guide surface 22 of the rail 12.

As described above, since the slider 17 sliding along the two rails 11 and 12 is always pressed against the respective rails by the elasticity of the tension cords 31 and 32, the both side plates 13 and 14 are always fixed. It is held on rails 11 and 12 by force.

[0010]

As described above, the device of the present invention comprises a slider that slides each side plate of the telescopic screen along each rail and a cylinder that connects the sliders, and the cylinder is formed by the slider that is opposed to the slider. Vertically slidably fits on the vertically protruding connecting part, one slider is on one rail by the other tension cord penetrating the telescopic screen, and the other slider is by one tension cord penetrating the telescopic screen. Since each of the other rails is pressed and held, unlike the conventional one where the opposing sliders are integrally attached to the same side plate,
The telescopic screen can be smoothly opened and closed not only vertically and horizontally but also vertically and vertically, obliquely or horizontally, and the distance between the two rails that guide the telescopic screen fluctuates partially. However, the force required for the opening and closing operation is always constant, and there is an excellent effect that the telescopic screen does not have to be opened and closed without permission even if the screen is installed in the vertical direction.
