Description

[Detailed description of the invention] [Industrial application field] This invention relates to a seat plate device for a seat shutter, and in particular to a seat plate device that can be easily attached to and replaced with a shutter seat. .

[Prior Art] As is well known, a seat plate is attached to the bottom of the shutter slat or the bottom of the shutter seat as a reinforcing material when opening and closing the shutter is completed, and a seat plate is attached to the ground surface of the seat plate. A rubber sheet is installed to maintain airtightness between the interior and exterior when the shutter is closed, and to protect the seat plate.

That is, as shown in FIG. 4, a seat plate 3 having approximately the same length as the opening frontage is attached so as to be suspended from a hanger 2 fixed to the lowest part of the seat 1. This seat plate 3 is made of metal,
It is a hollow box, and a rubber bottom seal 5 is fixed so as to cover the ground surface 4. The sheet 1 is sandwiched between a pair of mounting pieces 6, 6 formed protruding from the upper part, and then hung on a hanger 2. It is lowered and fixed to the seat 1 with bolts 7 and nuts 8.

[Problems to be solved by the invention] By the way, the seat plate device of the conventional seat shutter having the above-mentioned configuration does not require the seat plate to be replaced after the shutter is installed, or for repairs. When it becomes necessary to remove the seat plate 1, it is necessary to partially remove the seat 1 from the notch 9a of the guide rail 9, pull out the seat plate 3 laterally, and attach it in the same manner as shown in FIG. For this reason, there is a drawback that the seat plate cannot be replaced if there is an obstacle in the lateral direction, and an improvement has been desired.

[Means for Solving the Problems] The present invention was made to eliminate the problems of the conventional method described above, and the ground plane of the seat plate is joined with a hinge plate to form the seat plate into a half-split shape. The upper part of the seat plate can be opened and closed, so that the seat plate can be easily installed and removed.

[Example] Hereinafter, the seat plate device for a seat shutter according to the present invention will be specifically described based on the illustrated example.

In FIGS. 1 and 2, reference numeral 10 is a sheet shutter, and the upper end of a sheet 11 made of a woven fabric coated with PVC containing iron powder is placed in a shutter case 12 disposed above the opening. A shaft 1 that is horizontally suspended and rotated by a drive motor 13
The sheet 11 is attached to guide rails 15 and 1 disposed on both sides.
5, you can go up and down.

Reference numeral 16 denotes a seat plate device of the present invention, which is suspended and fixed to a hanger 17 formed at the lowermost end of the seat 11. The hanger 17 is attached to the sheet 1
A metal pipe 18 is disposed in the longitudinal direction at the lower end of the sheet, the pipe 18 is surrounded by the sheet end, and the sheet end is welded to the back side of the sheet.

The seat plate device 16 is composed of a metal seat plate 19 having a length substantially equal to the width of the opening, and a bottom seal 20 made of a flexible material such as rubber and placed below the metal seat plate 19. That is, the seat plate 19 has a cross section of approximately U.
A pair of mounting pieces 23, 23 with bolt holes 21 are formed at the upper ends of both flanges 21, 21, and the ground plane 24 has a plurality of hinge plates 25, 25, 25 in the longitudinal direction. The seat plate 19 has a half-split shape and is configured such that its upper part can be opened and closed. Furthermore, the ground plane 24 of the seat plate 19
In order to protect the seat plate 19 when the seat 11 is closed and the seat plate 19 is in contact with the ground, and to improve the effectiveness of indoor/outdoor sealing and waterproofing, there is a bottom seal with a U-shaped cross section made of chloroprene rubber. 20 is attached to cover the ground plane 24.

As shown in FIG.
3 and 23 to the front and back, and then seat 1
Insert the sheet 11 from the bottom surface of the hanger 17 provided at the lower end of the sheet 1, sandwich the sheet 11 between the mounting pieces 23, 23,
Bolt holes 22, 22 drilled in the mounting pieces 23, 23
Tighten and fix with bolts 26 and nuts 27.

[Effects of the invention] The seat plate device for a seat shutter according to the invention has the following effects:
The above configuration provides the following effects. That is, since the seat plate is split in half and its upper part can be opened and closed, it is possible to open the seat plate and easily attach and remove it from the bottom of the seat.

Furthermore, there is no need to remove the seat from the guide rail when installing or removing it, and the seat plate can be replaced even if there is an obstacle on the side of the shutter.
