Description

  According to the present invention, a continuous shutter device, that is, a shutter case that houses a single shutter body that can be opened and closed independently is attached between upper portions of left and right columns, and the shutter body is guided to the left and right columns so as to be movable up and down The present invention relates to a device in which a shutter device provided with a rail is provided in a lateral direction.

  FIG. 5 shows an example of a shutter device having a single shutter body. This shutter device SSA is constructed as a single shutter in which a girder 2 is installed between upper parts of left and right struts 1 so as to be vertically separated, and a large number of horizontal slats are connected to the upper parts of the girders and both struts so as to be bent. A shutter case 3 containing a winding drum (not shown) for winding a main body (not shown) is attached, and the longitudinal ends of the slats of the shutter main body on the back side (inside the site) of the pillars 1 on both sides. The rail 4 which guides up and down freely is provided.

As shown in FIG. 6, bearings of the rotating drum protrude from both side surfaces of the shutter case 3, and the side surface of the shutter case 3 is recessed more than the side surfaces of the support column 1 and the rail 4. Therefore, in order to improve the design aesthetics, as shown in FIGS. 5, 6, and 7, a side cover 5 having a side surface on the same surface as the side surface of the column 1 and the rail 4 is attached.
Nothing in particular

As exemplified in FIG. 8, it is conceivable to connect two single shutter devices (SSA1, SSA2) in the horizontal direction as shown in FIG. However, as described above, the side cover 5 of the shutter case 3 in the conventional single shutter device SSA has a side surface on the same surface as the side surfaces of the support column 1 and the rail 4, so that two single shutters as shown in FIG. It is impossible to install the devices close to each other in the lateral direction. Therefore, when two conventional single shutter devices are simply arranged side by side, a gap is formed between them, which is not preferable from an aesthetic point of view, and it is not preferable from the viewpoint of crime prevention because the inside can be seen from the gap. If the side cover on the side of the adjacent column is not attached, it can be installed close to some extent, but in that case, rainwater, dust, etc. enter the rail 4 etc. from between the shutter cases 3 on both sides. Cannot be prevented.

  The present invention has been made in view of the above points, and an object to be solved is to provide a shutter for a single shutter device in a continuous shutter device configured by connecting a plurality of single shutter devices in a lateral direction. Cases can be installed as close as possible, and rainwater and dust are prevented from entering the rails between adjacent shutter cases.

In order to solve the above problems, a continuous shutter device according to the present invention is
(a) Three or more struts having the same height are erected on a straight line at a predetermined interval on the ground.
(b) Build a girder between the tops of adjacent columns,
(c) Attaching a shutter case to the girders, attaching side covers to the column-side ends of both ends of the shutter case, and not attaching side covers to adjacent ends of the shutter case Install adjacent ends as close as possible,
(d) One shutter lift rail on the lower side of the shutter case on the back of the support columns at both ends, and two shutter lift rails on the lower side of the shutter case on the back of the intermediate support column. Installation,
(e) A connecting cover having an outline shape that is substantially the same as the outline shape of the outer surface of the shutter case is bridged between adjacent end portions of the shutter case, and the edges of the upper face plate and the front plate. At the overlapped portion, the upper portion of the upper surface plate is fixed to the beam, and the lower end portion of the front plate is fixed to the shutter lifting rail. Shielding a gap generated between the adjacent shutter cases,
It is characterized by.

According to the present invention, the neighboring ends of the shutter case mounted against neighboring the side surface cover is not mounted, can be mounted as close as possible an end thereof adjacent. Then, substantially the connection cover having the same outline shape coated fixed, a gap generated between the shutter case mounted against neighbor is shielded with the contour shape of the outer surface of the outer surface of the shutter case in the neighboring ends Therefore, the shutter case is connected to the entire length, and the gap is not exposed. Accordingly, not only is the aesthetic appearance improved, but there is no intrusion of rainwater, dust, or the like from the gap, and there is no risk of malfunction of the shutter due to such intrusion.

Moreover, since the connection cover is divided into an upper surface plate and a front surface plate, the connection cover can be easily manufactured. The connecting cover is divided into an upper plate and a front plate, and the end portions of the upper plate and the front plate are overlapped with each other, and the upper end portion of the upper plate is fixed to the shutter case at the overlapped portion. Since the lower end portion of the front plate is fixed to the rail, it is easy to attach the connecting cover to the shutter case, and the connecting cover is stably attached.

Furthermore, since the rail of the shutter device installed adjacent to the intermediate column is fixed, an effect of reducing the number of installation works by reducing the number of columns and a reinforcing effect by increasing the width of the column are obtained.

Next, an embodiment of the present invention will be described with reference to FIGS.
FIGS. 1A and 1B show an example in which the present invention is implemented as a double shutter device DSA in which two single shutter devices are connected, wherein FIG. 1A is a rear view and FIG. 1B is a side view. 2 is a simplified cross-sectional view of FIG. 1A, FIG. 3 is a cross-sectional view taken along the line XX of FIG. 2, and FIG. 4 is a cross-sectional view taken along the line Y-Y of FIG. The same reference numerals are used for members that are the same as or correspond to the components of the prior art shown in FIG.

  In FIG. 1, the support column 1 </ b> N disposed in the center has a width approximately twice that of the support columns 1 disposed on the left and right sides. And two upper and lower girders 2 and 2 are installed between the upper portions of the columns 1 and 1N; Reference numerals 21 and 22 in FIG. 3 denote fixing brackets and bolts for attaching the girders 2 and 2 to the columns 1 and 1N. 3 in FIG. 3 is a shielding plate for shielding the space between the upper and lower girders 2 and 2.

  As shown in FIGS. 2 and 4, one rail 4a for the left and right single shutter devices SSA1 and SSA2 is provided on the back surface (side surface in the site) of the central support column 1N, as shown in FIGS. 4a is fixed in a state where their back surfaces are close to each other. On the other hand, the other rails 4b and 4b for the left and right single shutter devices are fixed to the inner side surfaces of the pillars 1 and 1 on both sides, similarly below the lower beam 2 respectively. .

  A drum 7 is shown in each of the two upper and lower girders 2 and 2 installed between the upper portions of the columns 1 and 1N and the two upper and lower girders 2 and 2 installed between the upper portions of the columns 1N and 1. A shutter case 3 supported by a non-bearing is mounted by a known method. A side cover 5 is attached to the end of the shutter case 3 on the support column 1, 1 side. However, the side cover is not attached to the end of the shutter case 3 on the side of the center column 1N. Therefore, the adjacent side surfaces of the two shutter cases 3 are slightly separated from each other, and a gap s is generated therebetween. However, since any shutter case 3 is attached from the front side or the back side of the beam 2, the adjacent side surfaces of the shutter case 3 can be made as close as possible, and the width of the gap s is small.

Reference numeral 8 in FIGS. 2 and 3 denotes a connecting cover that shields the gap s from the outside. The connecting cover 8 is formed of a metal plate having a width larger than the width of the gap s, and the upper surface plate 81 and the front plate 82 are joined with their one end overlapped, so that the shutter case 3 is almost formed. The contour shape approximates the contour shape of the outer surface of the top wall 31 and the front wall 32 of the front wall 32. The upper surface plate 81 covers the upper surface of the upper surface wall 3 a of the shutter case 3, one end is fixed to the upper girder 2 with a screw n 1 or the like, and the other end of the upper surface plate 81 is the front of the upper surface wall 31 of the shutter case 3. At the side end portion, one end portion of the front plate 82 is overlapped with the end portion, and the screw n2 is screwed into the screw receiving member 33 fixed to the inside of the shutter case 3 from the overlapped portion. The front plate 82 extends to the lower end portion of the case 3 along the front surface of the shutter case 3, and is fixed to the upper end portion of the rail 4a with a screw n3.

  Thus, the connecting cover 8 having a width larger than the width of the gap s is stretched over and fixed to the ends of the shutter cases 3 on both sides, whereby the gap s is completely sealed. Therefore, there is no possibility that rainwater, dust, or the like enters the gap, and the opposite side surfaces of the shutter case 3 are not exposed to the outside.

  1 (b) and 9 in FIG. 4 is a shutter opening / closing controller attached to the inner surface of the rail 4 and 10 in FIG. 1 (b) has two stages on the opposing surfaces of the pair of left and right rails 4. It is a foreign object sensor for safety devices installed at a height.

  In the above description, the case where two single shutter devices are connected in series has been described. However, the present invention can be similarly applied to a case where three or more single shutter devices are connected in series. Further, the shutter main body provided in each single shutter device may be constituted by a grid that can be wound, in addition to a slat connected vertically.

1A and 1B show an example of a double shutter device according to the present invention, in which FIG. The simplified cross-sectional view of Fig.1 (a). XX sectional drawing of FIG. FIG. 4 is a cross-sectional view taken along line YY in FIG. 3. The perspective view which shows an example of the conventional shutter apparatus which has a single shutter.
