In this example, the face piece device A is a roll screen door that is configured to be wound up and down with the winding direction as the upper position of the opening.
[0010]
The face material 1 of the present example is divided into three in the height direction so that the width ratio is 1 at the upper and lower ends and 2 in the middle, and the screen door is formed by three nets made of, for example, synthetic resin or metal. At this time, by dividing the face material 1 into three parts, two winding shafts 2 are provided, and the winding shafts 2 are respectively provided between the three nets. In the example, the face material 1a located at the upper end, that is, the free end on the non-winding shaft side of the upper net is attached and installed in the upper lintel 6 defining the opening in this example. , For example, an aluminum-extruded material with a downward opening fixed to the frame mounting frame 3 having a U-shaped cross section, and in the other end, in this example, the face material 1c located at the lower end, that is, the non-net For example, the end of the take-up shaft side is processed in the same way with aluminum extruded material and a cushion material is installed at the bottom It is assumed that the movable frame 4 is held, and by rotating the two winding shafts 2 by this, the respective surface materials 1a, 1b, and 1c divided into the upper, middle, and lower parts are equalized by simultaneous winding of the respective winding shafts 2. The opening is opened and closed by winding, and the winding shaft 2 is accommodated in the housing mounting frame 3 so that the winding shaft 2 is positioned vertically when opened.
[0011]
In the present example, in the present example, the face materials 1a, 1b, 1c are held on the two winding shafts 2 at positions opposite to each other in the circumferential direction of the respective winding shafts 2. Simultaneous and equal winding of the face material 1 by the shaft 2 can be performed as smoothly as possible.
[0012]
At this time, each of the plurality of winding shafts 2 urges them in the winding direction, and the urging force of each winding shaft 2 biased in the winding direction becomes substantially equal to the weight below the winding shaft 2. By doing so, the movable frame can be stopped at any position in the winding direction.

That is, the take-up shaft 2 includes a take-up drum 21, a fixed shaft 22 inside the take-up drum 21, and a built-in coil spring interposed between the take-up drum 21 and the fixed shaft 22 with both ends fixed. 23, and the winding shaft 2 is rotated in the rewinding direction, that is, by rotating the winding shaft 2 in the extending direction of the face material 1, the coil spring 23 is wound and energized. The coil spring 23 can be biased and released along with the opening and closing in the vertical direction. At this time, the fixed shaft 22 inside the winding drum 21 has both ends in the longitudinal direction thereof taken up by the winding. For example, a sliding surface such as a vertical surface that slides in contact with the opposing wall surface of the guide rail 5 on both sides so that the guide rail 5 for guiding the shaft 2 slides up and down while maintaining a non-rotating state. The guide block 24 is directly or directly connected to the connecting shaft. Or one end is fixed to the guide block 24, and the other end is fixed to an internal bracket 25 installed in the take-up drum 21 so as to rotate relative thereto. The non-rotating state is maintained by the non-rotating up and down movement of 24, and the function as the fixed shaft 22 is secured while being installed in the rotating winding drum 21, and at this time, the winding drum 21 is The longitudinal end portion thereof is rotatably held by the non-rotating vertical movement guide block 24 so that the rotation and the winding and unwinding of the face material 1 by the winding shaft 2 can be performed. .
[0014]
In each of the winding shafts 2 in this example, the strength of the winding force of the coil spring 23 is set to the lower position of the winding shaft 2, for example, the lower weight of the face piece device A, that is, another winding. It is adjusted and installed so as to match the weight of the shaft 2 to the movable frame 4 and the like, and is set so as to balance the weight as much as possible. By stopping at an arbitrary position, the face piece device A can be partially opened and closed like a half-stretched half-open state. In the figure, 7 is a window stand and 8 is a pillar.
[0015]
In the face piece device A configured as described above, a plurality of winding shafts 2 can equally open and close the surface material 1 divided by simultaneous winding so that the winding shaft can be opened and closed. 2 is designed to fit inside the downwardly U-shaped frame mounting frame 3 installed in the lintel, while the intermediate plural winding shafts 2 and the other end, even if subjected to external force such as wind pressure, In other words, the movable shaft 4 at the lower end is held by the guide rail 5 so that the face material 1 can be maintained as much as possible without swinging the face material 1. By controlling the urging force of the shaft 2, it is possible to stop at an arbitrary position in the winding direction so that it can be partially opened and closed such as a half-open state.
[0016]
Although the illustrated example is as described above, the face material is divided into an even number or an odd number of 3 or more, and the stop is fixed by providing a lock means on the movable frame or the winding shaft. In this case, instead of the above-described one that can be wound up in the vertical direction by dividing the face body in the height direction, the face body can be wound up in the horizontal direction by dividing the face body in the width direction. In addition, the face material, the winding shaft, the frame mounting frame, the movable frame, the guide rail, and the like are necessary for the implementation of the present invention, including the configuration of the face body device as an awning, a decorative screen, an advertising banner, etc. Each specific shape, structure, material, number, relationship between these, the addition to these, etc. of the locking device etc. used according to can be in various forms as long as they do not contradict the gist of the invention.
