DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sealing device used in a smoking room for wood or a curing room for concrete products, which is used when a large opening is openably and closably covered with a sheet.

[0002]

2. Description of the Related Art Wood is housed inside for smoke treatment,
It is a treatment room for chemical treatment or a curing room for concrete products, etc.It is easy to open and close, and the construction cost is low, for sealing large openings that require airtightness. In many cases, a roll-up type sheet is used.

[0003]

However, when an opening having a large area is covered with a roll-up sheet, a gap can be eliminated above and below the opening, but it is inevitably provided on both sides of the opening. A gap occurs. In addition, there are many cases where a gap is generated on both sides due to the sheet being blown by the wind.

[0004] For this reason, there is a disadvantage that heat, smoke, steam, and the like in the room escape from the gaps on both sides of the seat to the outside, and rainwater or cold air enters from the outside. SUMMARY OF THE INVENTION It is an object of the present invention to provide a sheet which covers a large-area opening so as to be openable and closable, by simply increasing the airtightness of both sides thereof.

[0005]

According to the first aspect of the present invention, a metal L-shaped frame is provided on both sides of an opening which is openably and closably covered by a roll-up sheet. When a plate with a permanent magnet that opens and closes within a range of 90 ° is attached inside the corner portion of the L-shaped frame and both sides of the sheet are sandwiched between the plate and the L-shaped frame, the permanent The sheet is hermetically fixed to the plate by the action of the magnet being attracted to the plate. From this state, the plate is opened 90 ° and both sides of the sheet are released, enabling the sheet to be rolled up, and at the same time, the permanent magnet attracting action. The plate can be fixed inside the L-shaped frame while the plate is open.

Further, according to a second aspect of the present invention, in the first aspect, a rubber packing is attached to a side of the plate where the sheet is sandwiched.

Further, the invention according to claim 3 is characterized in that, in the invention according to claim 1 or 2, a handle that can be freely opened and closed is attached to the plate.

Further, the invention according to claim 4 is characterized in that, in any one of the inventions according to claims 1 to 3, the opening is a doorway of a closed space.

Further, the invention according to claim 5 is the invention according to any one of claims 1 to 4, characterized in that the opening is a window of a closed space.

Further, in the invention according to claim 6, in any one of the inventions according to claims 1 to 5, it is preferable that the opening is a product outlet of a wood smoking room or a concrete product curing room. It is a feature.

[0011]

When the sheet is wound up and the opening is opened, the plate is opened (turned) by 90 ° to the side of the opening and the permanent magnet is attracted to the inside of the side of the L-shaped frame. And the plate is fixed. When the seat is lowered along the inside of the frame from this state to close the opening, the plate is rotated forward by 90 ° and both sides of the sheet are sandwiched between the plate and the inside of the frame.

At this time, the permanent magnet on the plate side is attracted to the inside of the L-shaped frame with the sheet interposed therebetween, whereby both sides of the sheet are fixed. Since the height of the plate substantially covers the vertical position of both sides of the opening, both sides of the sheet are almost entirely sandwiched and fixed by the plate.

[0013]

BEST MODE FOR CARRYING OUT THE INVENTION A metal L-shaped frame to which a permanent magnet is attracted is attached to both sides of an opening, and a sheet is rolled up and down along the inside of the L-shaped frame. . At the corners of the L-shaped frames arranged on both sides of the opening, plates are attached using hinges or the like so as to open and close (deploy) within a range of 90 °.
Further, in this plate, a rubber packing is attached to the inside of the seat side, and further, a permanent magnet is attached by exposing to both sides at important points, and the plate can be fixed to the L-shaped frame by the permanent magnet. A handle is attached to the plate for opening and closing. The L-shaped frame may be made of a metal to which the permanent magnet is attracted only at the portion facing the permanent magnet, and may be made of, for example, aluminum, wood, brick, concrete or the like.

[0014]

1 is a perspective view of a wood smoking building embodying the present invention, wherein 1 is a smoking building main body, 2 is an opening for taking in and out of wood, and 3 is a cover of this opening 2. It is a roll-up type sheet. Reference numeral 4 denotes a sheet sealing device attached to both sides of the opening 2, and the sealing device 4 is attached to a metal L-shaped frame 5 and inside this corner as shown in FIGS. A hinge 6, a plate 7 that can be opened and closed within a range of 90 ° by the hinge 6, permanent magnets 8 attached to both sides of the plate 7, and a rubber packing 9 attached to the side sandwiching the sheet 3. Handle 1
0.

In the smoking building body 1, the sheet 3
To carry wood in and out of the interior. When closing the opening 2, the sheet 3 is lowered, the plate 7 is closed with the handle 10, and both sides 3a of the sheet 3 are sandwiched between the plate 7 and the inside of the L-shaped frame 5 (FIG. 4). As a result, sheet 3
Of the L-shaped frame 5 are fixed to each other.

When releasing the opening 2, the user holds the handle 10 and unfolds the plate 7 by 90 ° to open both sides 3a of the sheet 3. In this unfolded state, the plate 7
Are attracted to the inside of both sides of the L-shaped frame 5 and fixed (FIG. 5).

[0017]

As described above, in the present invention, since both sides of the sheet are pressed by the plate with the permanent magnet in the opening, a gap is generated on both sides of the opening, and heat or smoke is generated from the inside. Does not escape, is blown by the wind, and rainwater or cold does not enter the interior. As a result, quality control is thorough, heat loss is eliminated, and it is economical. Therefore, the present invention is particularly effective when a large-area opening is sealed with a roll-up sheet.

Further, the operation of the sealing plate is simple because the plate is simply opened and closed. Further, since the plate is provided with the permanent magnet, when the plate is opened and closed, the plate can be securely attracted and fixed to the L-shaped frame. In addition, since packing is attached to the plate, the sealing performance is improved.
