Description

[Detailed description of the invention] (Field of industrial application) This invention relates to an improvement of the seat in a sheet shutter that is used in combination with a normal shutter or used alone for indoor or outdoor decoration. be.

(Prior Art) In this type of shutter seat, when attaching the seat plate b to the lower end of the seat main body a, attachment means as shown in FIGS. 4 and 5 have been conventionally employed.

That is, in FIG. 4, the seat plate b and the abutment c are brought into contact with the front and back surfaces of the lower end of the seat body a, with the seat body a held between them, and both are fixed together with bolts and nuts. In FIG. 5, at the lower end of the seat main body a and the upper end of the seat plate b,
A plurality of attachment holes d and e are bored at appropriate intervals, and a rope f is inserted between these holes to connect them.

(Problems to be solved by the invention) However, with such a seat plate mounting structure, the downward tension applied to the seat main body a locally acts on the seat main body a, causing wrinkles to occur in the seat main body a, which deteriorates the appearance. Not only is the sheet main body a damaged, but the sheet main body a
Since the sheet main body a is perforated, when used outdoors, rainwater etc. may enter the sheet main body a through the perforations, causing stains or wrinkles to occur on the sheet main body a or causing the sheet to corrode. There was a problem that the durability period of a was significantly reduced.

The present invention provides a shutter sheet that solves these problems.

(Means for Solving the Problems) As shown in the drawings corresponding to the embodiments, the shutter sheet of the present invention integrally connects the upper part of the end sheet member 2 to the lower end of the sheet main body 1. The seat main body 1 and the end sheet member 2 are sandwiched between the upper opposing surfaces of the seat plate 3 and the plate-shaped fixing metal fittings 4, and bolts, nuts, etc. The seat plate 3 and the plate-shaped fixture 4 are integrally fixed using fasteners 5 and 6.

(Function) The seat plate 6 and the plate-shaped fixture 4 are attached to the end seat member 2 connected to the lower end of the seat main body 1 with a fastener 5,
6, the seat plate 3 can be attached to the seat main body 1 without making any holes, and the seat main body 1 can withstand long-term use without being adversely affected by rainwater, etc. Furthermore, if glass fiber, cloth, or the like is used as the end sheet member 2, there is no fear of corrosion. Further, the sheet main body 1 receives a uniform tension over its entire width via the end sheet member 2, thereby eliminating wrinkles.

(Example) To explain the example of the present invention with reference to the drawings, 1
The shutter sheet is mainly made of cloth or flexible synthetic resin sheet, the front and back surfaces are waterproofed, and the upper part of the oblong rectangular end sheet member 2 is overlapped over the entire width on the back side of the lower end. They are also integrally connected using a suitable adhesive or the like, and the lower part of the end sheet member 2 is suspended downward from the lower end of the sheet main body 1.

As this end sheet member 2, a chemically stable and mechanically strong sheet such as a glass fiber reinforced vinyl chloride sheet is used.

Reference numeral 3 denotes a seat plate having an L-shaped cross section, and the upper end portion of the vertical upper portion 3a of the seat plate 3 is brought into contact with the lower end surface of the seat main body 1 over approximately the entire width.
A plate-shaped fixing metal fitting 4 is brought into contact with the back surface of the end sheet member 2 facing the sheet main body 1, and a tightening member consisting of a bolt 5 and a nut 6 is inserted through the lower part of the end sheet member 2 hanging from the lower end of the sheet main body 1. By connecting and fixing the seat plate 3 and the plate-shaped fixing metal fittings 4 with attachments, the lower end of the seat main body 1 and the upper part of the end sheet member 2 are pressed between the seat plate 3 and the plate-shaped fixing metal fittings 4. , the seat plate 3 and the fixing metal fittings 4 are integrated into the seat main body 1 by the squeezing force.
It is attached to the bottom of the.

The seat plate 3 and the plate-shaped fixing metal fittings 4 are attached to the end sheet member 2 by drilling bolt insertion holes 8 and 9 at predetermined width pitches in the end sheet member 2 and the vertical upper part 3a of the seat plate 3, respectively. Then, after aligning the bolt insertion holes 10 drilled in the center of the plate-shaped fixture 4 with the respective insertion holes 8 and 9, the bolts 5 are inserted into the insertion holes 8, 9, and 9.
This is done by inserting the bolt into the bolt 10 and screwing the nut 6 onto the end of the bolt protruding from the fixture 4.

The shutter sheet configured in this way has a third
As shown in the figure, the sheet main body 1 is raised and lowered by the operation of the winding drum 12 while inserting and locking both side edges of the sheet main body 1 into the left and right guide rails 11 arranged and fixed along the inner walls on both sides of the entrance/exit. It is used as a sheet shutter.

FIG. 2 shows another embodiment of the present invention.
The lower end of the sheet member 2 is formed into a cylindrical part 7 containing a core material 13, and the cylindrical part 7 with the core is connected to the upper surface of the horizontal part of the seat plate 3 and the plate-shaped fixing metal fitting 4. It is interposed between the lower end surfaces of.

With this configuration, the cored cylindrical portion 7 presses against the lower end surface of the fixture 4 and tensions the sheet main body 1 more uniformly over the entire width through the end sheet member 4, thereby preventing the occurrence of wrinkles. It is something that can be eliminated.

(Effect of the invention) As described above, according to the shutter sheet of the invention, the upper part of the end sheet member 2 is integrally connected to the lower end of the sheet main body 1, and the sheet main body 1 and the end sheet member 2 are connected together. are sandwiched between the upper facing surfaces of the seat plate 3 and the plate-shaped fixture 4, and the seat plate is attached to the lower part of the end seat member 2 hanging down from the seat main body 1 using fasteners 5 and 6 such as bolts and nuts. 3 and plate-shaped fixture 4
Since the main body 1 of the seat is not made of any perforations, it is simply a seat plate 3.
Since the structure is sandwiched between the seat body 1 and the fixing metal fittings 4, there is no risk of rainwater etc. entering into the seat main body 1, thereby preventing the occurrence of corrosion, etc., and allowing long-term use without damage. In addition, the sheet main body 1 can be connected through the end sheet member 2.
The sheet shutter receives uniform tension over its entire width, eliminates the occurrence of wrinkles, and provides a sheet shutter with excellent appearance.
