I have.

  In the shutter device with a water blocking plate, first left and right ends of the water blocking plate are provided with first through holes, and the right and left ends are inserted into recesses of the guide rail. Therefore, after the water in the water stop plate is discharged from the first through hole, it flows downward along the inside of the concave portion of the guide rail. For this reason, it becomes difficult for water to pass to a pedestrian or the like passing under the shutter with the water blocking plate.

  In the shutter device with a water-stop plate, the water-stop plate is located on the outdoor side and extends in the left-right direction, and a thickness direction of the water-stop plate from a left-right edge of the first wall. A second wall extending toward the indoor side along the first wall and a third wall located below the first wall and the second wall. It is preferable to be provided on at least one of both end portions, the second wall, and left and right end portions of the third wall.

  In the shutter device with the water blocking plate, the first through-hole is not provided in the indoor portion of the water blocking plate. That is, the first through-hole is not provided in the wall facing the first wall located on the indoor side. For this reason, there is an effect that water is less likely to be applied to a pedestrian or the like who is indoors.

  In the shutter device with a water blocking plate, the water blocking plate has a plurality of divided bodies arranged in a vertical direction by dividing the hollow portion by a fourth wall, and each of the divided bodies is A fourth wall, a fifth wall located on the outdoor side and extending in the left-right direction, and a sixth wall extending from the left-right edge of the fifth wall toward the indoor side along the thickness direction of the divided body. The first through-hole is provided in at least one of left and right ends of the fourth wall, left and right ends of the fifth wall, and the sixth wall in each of the divided bodies. Preferably.

  In the shutter device with a water blocking plate, the water blocking plate is divided into a plurality of divided bodies, and each of the divided bodies is provided with a first through hole. Therefore, the efficiency of discharging water from the first through hole is improved as compared with the case where the water is not divided into a plurality of divided bodies.

  In the shutter device with a water blocking plate, it is preferable that the water blocking plate is provided with a second through hole communicating with the hollow portion and allowing air to be introduced into the hollow portion.

  In the shutter device with the water blocking plate, the water blocking plate is provided with the second through-hole, so that drainage from the second through-hole can be performed more quickly and efficiently.

  In the shutter device with a water blocking plate, it is preferable that the second through hole is provided in an upper wall of the water blocking plate.

  Therefore, the second through-hole can be provided at a higher position than when the second through-hole is provided at a portion other than the upper wall of the water blocking plate, so that air is efficiently introduced into the hollow portion. The drainage from the second through-hole can be performed more quickly and efficiently.

The water stop plate 60 provided with a drain hole 70 (first through hole) through which the water accumulated in the hollow portion 61 can be discharged and the right and left ends of the water stop plate 60 are inserted to move the water stop plate 60 up and down. A guide rail 20 having a concave portion 24 that can be guided along the movement.

  Thus, the drain holes 70 (first through holes) are provided at the left and right ends of the water stop plate 60, and the left and right ends are inserted into the concave portions 24 of the guide rail 20. For this reason, the recess 24 of the guide rail 20 surrounds the drain holes 70 at both left and right ends of the water stop plate 60. Therefore, after the water inside the water stop plate 60 is discharged from the drain hole 70, it flows downward along the inside of the concave portion 24 of the guide rail 20. For this reason, it becomes difficult for water to pass to a pedestrian or the like passing under the shutter 100 with the water stop plate.

  Further, the water stop plate 60 includes an outer wall 62 (first wall) located on the outdoor side, and a side wall extending from the left-right end edge 62 a of the outer wall 62 toward the indoor side along the thickness direction of the water stop plate 60. 63 (second wall) and a lower wall 65 (third wall) located below the outer wall 62 and the side wall 63. The drain holes 70 (first through holes) are provided at both left and right ends of the outer wall 62, the side walls 63, and both right and left ends of the lower wall 65.

  As described above, since the drain hole 70 (first through hole) is not provided in the indoor portion of the water stoppage plate 60, it becomes more difficult for water to pass to a pedestrian or the like in the indoor side.

  Further, since the water blocking plate 60 is provided with the air holes 80 (second through holes) that communicate with the hollow portions 61 and allow air to be introduced into the hollow portions 61, drainage from the drain holes 70 is performed more quickly. It can be carried out. Further, since the water inside the water stop plate 60 is quickly drained and the entire weight of the shutter 100 with the water stop plate is rapidly reduced, the load of the motor for raising the shutter 100 with the water stop plate is reduced. Also have.

  The air hole 80 (second through hole) is provided in the upper wall 66 of the water stop plate 60. Therefore, the air holes 80 can be provided above the case where the air holes 80 are provided in other portions (for example, the side walls 63), so that air can be efficiently introduced into the hollow portion 61. Can be.

The water-absorbing tape 272 is coated with a highly water-absorbing polymer having excellent characteristics such as water absorption efficiency, water absorption speed, and water retention. Therefore, when the water-absorbing tape 272 is submerged, it greatly swells and restricts water intrusion. As the water absorbing tape 272, for example, 3M (registered trademark) joint water stopping tape 2237 manufactured by 3M Company can be applied.

  As described above, in the present embodiment, the band-shaped waterproof rubber 271 to which the water-absorbing tape 272 is adhered is attached to the left and right ends of the inner wall 64 and the indoor end of the lower wall 65. I'm wearing Here, for example, at a corner where the side wall 63 and the lower wall 65 intersect, a gap is easily generated between the guide rail 20 and the floor surface 13 (see FIG. 1). Further, when many irregularities are provided on the floor surface 13, a gap is easily generated between the floor surface 13 and the waterproof rubber 271. However, since the water-absorbing tape 272 is stuck to the water-stopping rubber 271, when water is immersed from the outdoor side, the water-absorbing tape 272 is immersed and greatly swells, and the above-described gap can be closed to restrict water intrusion. .

  As mentioned above, although the embodiment of the present invention was illustrated, the above-mentioned embodiment is an example and is not intended to limit the scope of the invention. These embodiments can be implemented in other various forms, and various omissions, replacements, combinations, and changes can be made without departing from the spirit of the invention. These embodiments are included in the scope and gist of the invention, and are also included in the invention described in the claims and their equivalents. Further, the configuration and shape of each embodiment and each modified example can be partially replaced and implemented. In addition, the specifications (structure, type, direction, shape, size, length, width, thickness, height, number, arrangement, position, material, etc.) of each configuration and shape are appropriately changed and implemented. can do.

  For example, in the first embodiment, the drain holes 70 (first through holes) are provided at the left and right ends of the outer wall 62, the side wall 63, and the left and right ends of the lower wall 65. At least one of the side wall 63 and the lower wall 65 may be used. For example, the drain hole 70 may be provided only on the side wall 63 or only on the outer wall 62. Further, the air holes 80 (second through holes) may be provided at both left and right ends of the upper wall 66.

  In the second embodiment, the drain holes 70 (first through holes) are provided at the left and right ends of the partition wall 82, the left and right ends of the outer wall 162, and the side walls 163. However, the drain hole 70 may be provided on the outer wall 162 (fifth wall) located on the outdoor side. Further, the drain hole 70 (first through hole) may be provided at the center of the partition wall 82 in the left-right direction. Further, in the above embodiment, the diameters of the drain holes 70 (first through holes) arranged vertically are the same, but for example, the drain holes 70 may gradually increase in diameter downward. Since the water pressure due to the accumulated water is higher on the lower side than on the upper side, the diameter of the lower drain hole 70 can be increased, and the drainage efficiency from the drain hole 70 can be increased.
