Description

[Detailed Description of the Invention] The present invention relates to a seat plate attached to the lower end of a shutter curtain that moves up and down in a shutter installed in the frontage of a building.

Conventionally, in shutters installed at openings such as doorways and windows of buildings, an inverted T-shaped seat plate with a horizontal surface is attached to the lower end of the shutter curtain that rises and lowers at the frontage, and when the shutter curtain is lowered, Its lower end is brought into close contact with the floor surface for good closure.

Also, as a safety device when lowering the shutter,
A structure has been proposed in which a cover that can be raised and lowered is provided on the seat plate to detect collisions with obstacles below it. It has been known.

However, in the case of the conventional shutter mentioned above,
When opening the shutter curtain, if the shutter curtain is rolled up excessively, the seat plate will be drawn into the bottom part, and if it is not rolled up enough, the seat plate will be exposed from the bottom surface of the bottom part, so in either case, the appearance is unfavorable. Particularly in electric shutters, errors often occur over time in detecting the up and down positions of the shutter curtain, resulting in the above-mentioned inconvenient situation.

The present invention aims to eliminate these drawbacks in view of the actual situation of the prior art.The present invention is designed to have the same length as the width of the shutter curtain that is raised and lowered from the shutter case, and has a groove in the upper edge. A movable body formed in an inverted T-shape with the upper part of the vertical part protruding from the slot and the horizontal part movable up and down within the hollow body, In a shutter seat plate formed by connecting the vertical part of the movable body to the lower end of the shutter curtain,
A hollow elastic body made of sponge rubber is built into the upper and lower surfaces of the horizontal part of the movable body, respectively, between the upper and lower corresponding surfaces of the hollow body, and the height of the hollow body is adjusted to the shutter case. By configuring the bottom part of the shutter curtain to correspond to the depth of the recess formed by the stopper, a stopper is provided in the bottom part to align the bottom surface of the hollow body with the bottom surface of the bottom part when the shutter curtain is raised. , and by always setting the amount of elevation of the shutter curtain a little extra, when the shutter curtain is raised, the excess amount of elevation is absorbed by the hollow elastic body at the top, and the hollow elastic body It is not possible to ensure that the lower surface and the lower surface of the bottom part are aligned, and even when the shutter curtain is lowered, the hollow elastic body below absorbs the excess amount of descent, and the hollow body relative to the floor surface is The purpose of the present invention is to provide a seat plate for a shutter that can improve the closeness of the shutters and provide excellent closing performance.

The structure of the present invention will be explained with reference to an embodiment shown in the drawings. 1 is a shutter curtain, and this shutter curtain 1 is guided by guide rails 2, 2 installed on both sides of the frontage of a building. It can be raised and lowered freely. 3 is a shutter case in which a winding device for the shutter curtain 1 is built-in. A seat plate 4 having the same length as the width of the shutter curtain 1 is attached to the lower end of the shutter curtain 1. This seat plate 4 is constructed as follows.

That is, 5 is a hollow body, and this hollow body 5
is a rectangular cylindrical body with a flat bottom surface, and a movable body 6 that can move up and down is provided inside the hollow body 5. This movable body 6 has an inverted T shape having a horizontal portion 6a and a vertical portion 6b.
The upper part of the vertical part 6b of the movable body 6 is
Hollow elastic bodies 7 are made to protrude from slots formed in the longitudinal direction on the upper surface of the hollow body 5, and between the upper and lower surfaces of the horizontal portion 6a and the corresponding surfaces of the hollow body 5, respectively.
7 and 8 are interposed, and the hollow elastic bodies 7, 7
and 8 are hollow sponge rubber bodies, and the upper or lower sides of these hollow elastic bodies 7 and 8 are fixed to a horizontal member as appropriate. The vertical portion 6b of the movable body 6 is bendably connected to the lower end of the shutter curtain 1.

Reference numeral 9 denotes a bottom portion of the opening, and a pair of stoppers 10 are provided in the bottom portion 9, facing each other across the shaft of the shutter curtain. This stopper 10
In order to align the lower surface of the hollow body 5 of the seat plate 4 with the lower surface of the lower part 9 when the shutter curtain 1 is raised, its mounting position is adjusted to the height of the hollow body 5. The winding device for the shutter curtain 1 is
The operating conditions are set so that the shutter curtain 1 is always raised or lowered a little more. For example, in the case of an electric shutter, the detection positions of the rising and falling points of the shutter curtain may be set to satisfy the above conditions.

In the structure constructed as described above, when the shutter curtain 1 is lowered, the seat plate 4 at the lower end thereof comes into close contact with the floor surface, and the opening is closed by the shutter curtain 1. The surplus of the downward movement of the shutter curtain 1 is absorbed by the hollow elastic body 8 by the movable body 6 which moves downward in the direction of pressing the hollow elastic body 8 below the seat plate 4 which is in close contact with the floor surface. The seat plate 4 is always in close contact with the floor surface and can be made to conform to the undulations of the floor surface to some extent, so that the shutter has an extremely high degree of closure (FIG. 3). On the other hand, when the shutter curtain 1 is raised, the seat plate 4 at the lower end of the shutter curtain 1 is moved by the stopper 10 in the bottom part 9.
The excess lifting amount of the shutter curtain 1 is absorbed by the upper hollow elastic bodies 7, 7 via the movable body 6. Therefore, when the shutter curtain 1 is raised, the lower surface of the seat plate 4 is reliably aligned with the lower surface of the bottom portion 9, so that the appearance is not damaged (FIGS. 4 and 5).

In addition, the same effect can be expected even if the seat plate 4 according to the present invention is used for a movable smokeproof hanging wall made of cloth, for example. Furthermore, since the hollow elastic body 8 below the seat plate 4 is a hollow sponge rubber body, a tape switch can be housed in the hollow part and used as a safety switch for the shutter.

In short, the present invention consists of a rectangular cylindrical hollow body formed to have the same length as the width of the shutter curtain that is lifted and lowered from the shutter case, and a slotted hole in the upper edge; A shutter comprising a movable body whose vertical part has an upper part protruding from the slot and whose horizontal part can move up and down within the hollow body, and the vertical part of the movable body is connected to the lower end of the shutter curtain. In the seat plate, the upper surface and the lower surface of the horizontal part of the movable body include the upper part of the hollow body,
A hollow elastic body made of sponge rubber is built in between the lower corresponding surface and the height of the hollow body corresponds to the depth of the recess formed by the stopper in the shield of the shutter case. Since I configured it,
By always setting the amount of elevation of the shutter curtain a little extra, when the shutter curtain is raised, the hollow elastic body at the top absorbs the excess amount of elevation, allowing the seat plate to However, there is no risk of damaging the bottom part, and the bottom surface of the hollow body and the bottom surface of the bottom part can be reliably aligned.
Even when the shutter curtain is lowered, the excess amount of descent is absorbed by the hollow elastic body below, which improves the closeness of the hollow body to the floor surface and provides excellent closing performance. It has a useful practical effect.
