BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet retaining device for a seat shutter which is installed in an opening of a building, a partition opening in a building, and other openings of a show window.

[0002]

2. Description of the Related Art The above-mentioned sheet shutter is provided with, for example, a colored sheet or a sheet on which a photograph, a landscape image, or a pattern for decoration is drawn, guided by guide rails standing up and down on the left and right sides of the opening. Freely provided, for example, there are a winding type as shown in Japanese Utility Model Publication No. 63-29092 and a folding type as shown in Japanese Utility Model Publication No. 63-64892, and The above seats may be installed alone or in combination with a slat shutter.

Due to the action of wind pressure on the seat surface of such a sheet shutter and the air flow in the building due to the air conditioner,
The seat may bulge or flap, and the edge of the seat may slip out of the guide rail. For example, Japanese Utility Model Laid-Open No. 63-184990 proposes a technique for preventing the above-described inconvenience from coming off the sheet edge.

As shown in FIG. 9, this one is provided with an auxiliary seat 33 on the seat 31 so as to form an open engagement portion 32 between the seat 31 and the swingable wing body. A disengagement prevention body 35, in which 34 is retracted into the engagement portion 32, is provided in the guide rail 36, and when the seat 31 receives wind pressure, the seat 31 is pinched by the disassembly prevention body 35 and the guide rail 36. Is configured.

According to this structure, the sheet edge can be properly prevented from coming off. However, since the sheet itself has flexibility, it is necessary to form the open engagement portion 32 at the sheet edge. In addition, it takes a lot of time and manpower to set the edge of the sheet in the guide rail and replace the sheet when the sheet shutter is installed.

[0006]

That is, in the above-described sheet winding type shutter, generally, the upper end of the sheet is wound by, for example, a slide fastener or a velvet fastener so that only a necessary sheet portion can be replaced. Although it is configured to be releasably connected to the sheet piece on the drum side, when the above-mentioned sheet edge removal prevention technology is adopted, the engaging section is removed when the sheet edge is set in the guide rail. While engaging the preventive body, the procedure must be taken such that the edge of the sheet is fed downward from the upper side of the guide rail in order to connect the upper end of this sheet to the sheet piece on the drum side, or when replacing the sheet. , Release the connection of the upper end of the sheet to the sheet piece on the drum side, and then raise the sheet above the guide rail. Procedure as it does not must be taken, it was required a great deal of time and manpower from the fact that a large-scale work at heights is forced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings in the case of a retractable storage type arranged in parallel with a slat type shutter. In FIG. 1, reference numeral 1 is a slat type shutter (hereinafter, simply referred to as a shutter), and as shown in FIG.
A rail member 4 in which guide rails 2 and 3 for slat and seat are integrally formed is erected on both sides of the opening 5 of the building, and is slidable by being guided by the guide rail 2 for slats therein. A plurality of first and second slats 6 are connected to each other and the slats 6 are installed in the upper part of the opening 5.
It is configured to be wound around the drum 7.

A sheet shutter 8 is guided by the sheet guide rail 3 to move up and down. The sheet piece 10 is wound around a second drum 9 which is installed on the upper portion of the opening 5 and is free to wind. An upper end of a sheet 11 on which decorative photographs, landscape images, patterns and the like are drawn is connected to the sheet piece 10 via a slide fastener 12, for example.

As shown in a partially enlarged view of FIG. 3, the sheet 11 has an ink layer b, such as a pattern, printed on one side of a sheet material a made of glass fiber, and a vinyl chloride layer c on both sides. Each of the lower end of the sheet 11 and the lower slat 6 of the shutter 1 is coated.
The sheet 11 is connected to a common seat plate 13 that is slightly shorter than the opening width of the opening 5, and the sheet 11 is wound up on the second drum 9 as the shutter 1 is wound up. In the closed state, the sheet 11 is spread on one side surface of the shutter 1 with a gap. The locking body 14 that locks the lower end of the seat 11 to the seat plate 13 is located inward through the opening 15 of the guide rail 3 together with the edge of the seat 11.

Reference numeral 16 denotes a locked member which is formed narrower than the opening width of the guide rail 3 and can be inserted into the opening 15 of the guide rail 3, and which is vertically spaced from the seat 11 by a predetermined distance. It is provided on both sides of both ends. More specifically, the locked member 16 has a thickness of 1 mm.
It is made of resin with a width of 0 mm and a length of 110 mm, and is welded to the edge of the sheet 11 by a high frequency welder at intervals of 50 to 80 cm in the vertical direction.

It should be noted that, when the locked member 16 rides on the second drum 9 while the sheet 11 is being wound around the second drum 9, the winding diameter of the sheet 11 becomes large. By preventing the locked members 16 from overlapping with each other in the winding state of 11, the enlargement of the sheet winding diameter can be suppressed. Alternatively, preferably, as indicated by an imaginary line d in FIG. 1, the sheet winding length of the second drum 9 is set to be slightly shorter than the width of the sheet 11. That is, the shaft end of the drum 9 is attached to the sheet 1
That is, the locked member 16 is set to be slightly less than the edge of No. 1 so that the locked member 16 does not ride on the second drum 9. With such a configuration, the winding diameter of the sheet 11 can be suppressed to a small diameter even when the locked members 16 are continuously provided.

Reference numerals 17 and 17 denote locking members, which are preferably made of, for example, an acrylic plate or the like whose front end side is processed to have an acute angle, and one side surface of the biasing means 18 formed by bending a plate spring into a V shape. > is, are bonded by a double-sided tape 19 to the surface side obtained by processing the distal end side of the locking member 17 at an acute angle, its
The other side surface of the biasing means 18 of the

Is, in the above two states to the locking member 17, 17 resiliently biased to the seat 11 side each other front end side of, and, with the rear end side was Tsuppara the face plate 3a inner surface of the opening 15 side of the guide rail 3 There is.

By the above-described locked member 16, locking member 17 and biasing means 18, a sheet edge retaining device 21 is provided.
According to such a configuration, while the locking member 17 is bent through the opening 15 of the guide rail 3, the locking member 14 and the locked member 16 at the edge of the seat 11 are formed.
Is pushed into the guide rail 3 and the locked member 16 is locked to the tip side of the locking member 17, so that the edge of the sheet 11 is pulled out at the same time when the edge of the sheet 11 is set in the guide rail 3. After that, by pulling up the sheet 11 and connecting the upper end of the sheet 11 to the sheet piece 10 by the slide fastener 12,
Installation of the seat shutter 8 or replacement of the seat 11 is achieved.

When the seat 11 is replaced, the seat 11 is removed as follows. That is, the slide fastener 1 of the sheet 11 with respect to the sheet piece 10
2, the tool such as a screwdriver is inserted into the opening 15 of the guide rail 3 to expand the locking member 17, and the locking of the locking member 17 to the locked member 16 is released . In this state , the locked member 16 can be taken out of the opening 15 together with the seat 11 . Any of the removal of the seat 11 and the setting of the seat 11 described above can be performed safely and easily on the ground and with a small amount of manpower in a short time.

In the embodiment, the biasing means 18 is separately provided so as to elastically bias the tip end side of the locking member 17 toward the seat 11 side. For example, FIG.
As shown in the face plate 3b facing each of the guide rails 3,
As a structure in which the locking member 17 is integrally connected to the mounting member 22 for the inner surface of 3c in a state of being flexibly deformable in a direction orthogonal to the surface of the seat 11, that is, in a state where the biasing means 18 is provided, It may be attached to the guide rail 3 with a tape 23 or the like. Alternatively, as shown in FIG. 4B, the locking member 17 is integrally connected to the mounting member 22 press-fitted into the U-shaped portion 3d of the rail member 4 in a state in which the biasing means 18 is provided. Then, the mounting member 22 may be press-fitted into the U-shaped portion 3d to be fixed. In addition, the sheet 11 is sandwiched between the front end portions of the pair of locking members 17, for example, as shown in FIG.
As shown in FIG.
Alternatively, the locking member 17 may be provided only on one side in a state where the locking member 17 is provided relative to this.

Further, although the locked members 16 are provided at the edges of the seat 11 at intervals vertically, the locked members 16 may be provided over the entire length of the edges of the seat 11 in this case. If the locked member 16 is made of resin, it will be soft. However, as shown in FIG. 6, for example, as shown in FIG. Alternatively, as shown in FIG. 7, it is possible to divide the locking member 17 in the vertical direction, and when such a structure is adopted, the upper and lower edges of the locking member 17 can be configured. The portion is chamfered or tilted as shown in the figure to facilitate the expansion of the locking member 17 by the locking body 14 when the locking body 14 for locking the lower end of the seat 11 to the seat plate 13 is moved up and down. It is preferable to do so.

Although the above-mentioned embodiments are of the so-called sheet winding type which is used together with the slat type shutter 1, the subject of the present invention is not limited to such a winding type. That is, as shown in FIG. 8, support bars 24 having a length extending over the left and right guide rails 3 are provided on the seat 11 at predetermined intervals in the vertical direction, and the lowest support bar 24 is lifted to fold the seat 11. By providing the drive opening / closing means 25 for opening,
For a so-called folding type sheet shutter 8 in which only the seat 11 is independently opened and closed by driving, a locked member 16 having a width narrower than the opening width of the guide rail 3 is targeted.
Are provided on both end sides of the seat 11, more specifically, on the ends of the support bar 24 projecting to both sides in the width direction of the seat 11, while being locked to the engaged member 16 and pulling out the seat 11 to the outside of the rail. The locking member 17 for controlling the stop can be provided by being provided in the guide rail 3 in a state of being flexibly deformable in the direction orthogonal to the seat surface.
