As shown in FIGS. 4 and 5, the water stop plate 4 has, for example, a panel portion 41, water stop rubbers 42 and 43, a hooked portion 44, sliders 45 and 46, and a cover portion 47. are doing. The panel part 41 is also called a waterstop main body or the like.

Both ends of the panel portion 41 in the Y direction are supported by grooves 5a (see FIG. 5) of the guide rails 5 so as to be movable in the Z direction between the closed position P1 and the open position P2. The panel portion 41 has rigidity to withstand water pressure when submerged. The panel portion 41 is configured by, for example, filling the inside of a frame of a lightweight metal plate containing aluminum and having a rust-proof property with a filler.

The waterproof rubber 42 (see FIG. 4) is provided, for example, on the rear surface of the panel portion 41 on the indoor side, and covers the lower end portion of the rear surface. The waterproof rubber 42 has a predetermined width in the Z direction and is formed in a strip shape elongated in the Y direction. The waterproof rubber 42 is made of an elastomer such as synthetic rubber, for example. The water stop rubber 42 is also called a bottom water stop rubber, a first seal member, a first section, or the like.

The water stop rubber 42 is interposed between the step surface 111 provided on the installation surface 110 and the panel portion 41 when the water stop plate 4 is positioned at the closed position P1. The waterproof rubber 42 is elastically compressed by being sandwiched between the stepped surface 111 and the panel portion 41 to generate surface pressure. This surface pressure prevents water from entering the room from between the step surface 111 and the panel portion 41 .

The waterproof rubber 42 is not limited to this example, and may be provided on the step surface 111 side, for example. The stepped surface 111 intersects (perpendicularly) with a horizontal surface 112 on which the shutter curtain 3 abuts on the installation surface 110 and is one step lower forward (outdoor side) than the horizontal surface 112 . The step surface 111 can also be called a vertical surface or the like.

The waterproof rubber 43 is provided, for example, on the rear surface of the panel portion 41 and covers both ends of the rear surface in the Y direction. As also shown in FIG. 5, the waterproof rubber 43 has a predetermined width in the Y direction and is formed in a strip shape elongated in the Z direction. The waterproof rubber 43 is made of an elastomer such as synthetic rubber, for example. The water stop rubber 43 is also called a side water stop rubber, a second seal member, a second section, or the like.

The water stop rubber 43 is interposed between the indoor side surface of the groove portion 5a and the panel portion 41 when the water stop plate 4 is positioned at the closed position P1. The waterproof rubber 43 is elastically compressed by being sandwiched between the side surface of the groove portion 5a and the panel portion 41 to generate surface pressure. This surface pressure prevents water from entering the room from between the side surface of the groove portion 5 a and the panel portion 41 . In addition, the waterproof rubber 43 is not limited to this example, and may be provided on the groove portion 5a side, for example.

The hooked portion 44 is provided on the rear surface of the panel portion 41, for example. The hooked portion 44 protrudes from the panel portion 41 toward the shutter curtain 3, that is, rearward (opposite to the X direction) and extends in the Y direction. The hooked portion 44 is positioned so as to overlap the seat plate 32 in the Z direction. The hooked portion 44 is also called a hook plate or the like.

As shown in FIG. 4, the hooked portion 44 faces the seat plate 32 with a gap in the Z direction when the water stop plate 4 is positioned at the closed position P1. In this embodiment, for example, the amount of overlap between the hooked portion 44 and the seat plate 32 in the X direction is set to be larger than the width of the inclined surface 5b1 (see FIG. 3) of the guide rail 5 along the X direction. ing.

As a result, for example, even when the water stop plate 4 is guided downward and indoors by the inclined surface 5b1, the shutter curtain 3 and the water stop plate 4 are interlocked with each other due to the hooking of the seat plate 32 and the hooked portion 44 in the Z direction. Canceling the state is suppressed.

In this embodiment, the upper surface of the seat plate 32 is provided with an elastic member 33 made of, for example, a foamable synthetic resin material or rubber. The elastic member 33 suppresses cushioning between the seat plate 32 and the hooked portion 44 by being interposed between the seat plate 32 and the hooked portion 44 . The elastic member 33 is also called a cushioning material, a cushioning material, or the like.

The sliders 46 (see FIG. 5) are provided, for example, on both end surfaces of the panel portion 41 in the Y direction. The slider 46 is movably supported in the Z direction in the groove 5b provided at the bottom of the groove 5a. The slider 46 is, for example, a roller or the like that can roll on the side surface of the groove portion 5b or the above-described inclined surface 5b1 (see FIG. 3). This allows the water stop plate 4 to move smoothly along the guide rails 5 .

The sliders 45 (see FIG. 2) are provided, for example, at both ends in the Y direction on the front surface of the panel section 41 on the outdoor side. The slider 45 is, for example, a roller or the like that can roll on the inclined surface 52 a of the guide mechanism 52 . Note that the slider 45 is not limited to this example, and may be provided so as to be non-rotatable with respect to the panel section 41 .

The cover portions 47 (see FIG. 4) are provided, for example, at the lower two corners of the front surface of the panel portion 41 on the outdoor side. The cover portion 47 has, for example, a front wall 47a, a lower wall 47b, a bent portion 47c, and the like, and covers corners of the panel portion 41. As shown in FIG. That is, the cover portion 47 functions as a corner guard for the panel portion 41 . Thereby, the protection of the corners of the panel portion 41 can be enhanced.

Further, the bent portion 47c is slidably supported on the inclined surface 51a of the guide mechanism 51. As shown in FIG. As shown in FIGS. 2 and 3, in this embodiment, when the water stop plate 4 moves toward the closed position P1, the bent portion 47c and the sliders 45 and 46 move toward the inclined surfaces 51a, 52a and 5b1 of the guide mechanisms 51 and 52. slides downward and indoors along the line, and the water stop plate 4 moves downward and indoors. As a result, the water stop rubber 42 is elastically compressed in the X direction by the panel portion 41 and the step surface 111, and the water stop rubber 43 is elastically compressed in the X direction by the panel portion 41 and the indoor side surface of the groove portion 5a. effectively compressed state is obtained.

As described above, in the present embodiment, for example, the water stop device 1 is provided so as to be able to abut against the installation surface 110 below the building opening 101, and moves vertically to open and close the building opening 101. 3, a winding device 6 (driving device) positioned above the building opening 101 and having a winding shaft 12 (driving mechanism) for winding and driving the shutter curtain 3; A water stop plate 4 arranged in the direction (outdoor side) and provided so as to be able to abut against the installation surface 110 and configured to be vertically movable in conjunction with the shutter curtain 3 .

According to such a configuration, since the water stop plate 4 and the shutter curtain 3 can be provided in parallel in the X direction (outdoor side) of the building opening 101, for example, the open position P2 (open state), it is possible to suppress narrowing of the building opening 101 by the water stop plate 4 . Further, for example, in the closed position P1 (closed state) where the building opening 101 is closed, rainwater or the like flowing from the outdoor side to the indoor side can be doubly blocked by the water stop plate 4 and the shutter curtain 3. It is easier to suppress the inundation from

Further, in the present embodiment, for example, the water stop plate 4 is shifted from the shutter curtain 3 toward the frame 103 to which the winding device 6 is attached. According to such a configuration, for example, at the open position P2 (open state) where the building opening 101 is opened, the water stop plate 4 is housed (wound up) in the frame 103 and the winding shaft 12. can be stored in the space in the X direction between

Further, in the present embodiment, for example, the water stop plate 4 is accommodated in the shutter case 11 (accommodating portion) of the winding device 6 together with the shutter curtain 3 at the open position P2 (open state) where the building opening 101 is opened. be. According to such a configuration, for example, the water stop plate 4 is prevented from being exposed from the shutter case 11 at the open position P2 as much as possible, and the water stop plate 4 impairs the appearance or narrows the building opening 101. can be suppressed.

In this embodiment, the installation surface 110 is provided with a horizontal surface 112 with which the shutter curtain 3 abuts, and a stepped surface 111 that crosses the horizontal surface 112 and with which the water stop plate 4 abuts. According to such a configuration, for example, compared to the case where the water stop plate 4 contacts the horizontal surface 112 together with the shutter curtain 3 at the closed position P1, the intrusion path of rainwater or the like from the outdoor side to the indoor side is bent, Inundation from the building opening 101 is more likely to be suppressed.

Further, in the present embodiment, for example, the water stop plate 4 is positioned in the X direction (outdoor side) with respect to the shutter curtain 3, and is inclined to guide the water stop plate 4 downward and toward the indoor side step surface 111. A guide mechanism 51 provided with a surface 51a is provided. According to such a configuration, for example, the water stop plate 4 can be guided toward the step surface 111 by the inclined surface 51a of the guide mechanism 51.

Further, in the present embodiment, for example, the shutter curtain 3 has a seat plate 32 that can come into contact with the installation surface 110 , and the water stop plate 4 protrudes toward the shutter curtain 3 and vertically extends from the seat plate 32 . A hooked portion 44 that interlocks with the shutter curtain 3 by being hooked is provided. According to such a configuration, for example, the water stop plate 4 can be interlocked with the shutter curtain 3 by a relatively simple configuration utilizing the hooking between the seat plate 32 and the hooked portion 44 .

[First modification]
FIG. 6 is a cross-sectional view of part of a water stop device 1A of a first modified example. The water stop device 1A has the same configuration as the water stop device 1 of the above embodiment. Therefore, the water stop device 1A can obtain the same actions and effects as those of the above-described embodiment based on the same configuration.

However, as shown in FIG. 6, this modified example is different from the above-described embodiment in that the seat plate 32 is provided with a protruding portion 32a that protrudes in the Z direction. The protruding portion 32 a is positioned, for example, substantially in the center of the seat plate 32 in the Y direction, and extends in the Y direction along the hooked portion 44 . Note that the protrusions 32a are not limited to this example, and for example, a plurality of protrusions 32a may be intermittently provided in the Y direction.

Further, the hooked portion 44 is provided with an opening portion 44a through which the projecting portion 32a penetrates in the Z direction. In this embodiment, for example, the contact between the edge of the opening 44a and the projecting portion 32a restricts the movement of the water stop plate 4 in the XY plane with respect to the shutter curtain 3. As shown in FIG. That is, the protruding portion 32a and the edge of the opening 44a are an example of the positioning portion.

Thus, according to the present modification, for example, the protruding portion 32a and the opening 44a suppress positional deviation of the water stop plate 4 with respect to the shutter curtain 3 in the cross direction (XY plane) crossing the Z direction, As a result, the interlocking state between the shutter curtain 3 and the water stop plate 4 can be more reliably obtained by the engagement between the seat plate 32 and the hooked portion 44 .

In this modified example, the seat plate 32 is provided with the projecting portion 32a, and the hooked portion 44 is provided with the opening 44a. 44 may be provided with a protrusion and the seat plate 32 may be provided with an opening.

[Second modification]
FIG. 7 is a cross-sectional view of part of a water stop device 1B of a second modification. The water stop device 1B has the same configuration as the water stop device 1A of the first modified example. Therefore, the water stop device 1B can obtain the same actions and effects as those of the first modification based on the same configuration.

However, as shown in FIG. 7, this modified example is different from the first modified example in that the seat plate 32 is provided with a loop-shaped projecting portion 32b. The protruding portion 32b is positioned, for example, substantially in the center of the seat plate 32 in the Y direction, and extends in the Y direction along the hooked portion 44. As shown in FIG. The projection 32b is provided with an opening 32c penetrating in the Y direction. In addition, the projecting portion 32b is not limited to this example, and for example, a plurality of projecting portions 32b may be intermittently provided in the Y direction.

Further, the hooked portion 44 is, for example, protruding from the panel portion 41 in the direction opposite to the X direction and extending in the Y direction in a substantially L shape. The hooked portion 44 is also called a hook portion or the like. In this embodiment, for example, the hooked portion 44 and the projecting portion 32b are engaged with each other by inserting the tip of the hooked portion 44 into the opening 32c. As a result, the movement of the water stop plate 4 in the X, Y, and Z directions with respect to the shutter curtain 3 is restricted, and the interlocking state between the shutter curtain 3 and the water stop plate 4 can be more reliably obtained. In particular, as the shutter curtain 3 descends, the top wall of the protruding portion 32b pushes the hooked portion 44 downward, thereby allowing the water stop plate 4 to move from the open position P2 to the closed position P1 more reliably.

The water stop plate 4 is not limited to this example. For example, in the closed position P1, the seat plate 32 is slightly spaced upward from the horizontal surface 112, and the upper wall of the projecting portion 32b is positioned so that the hooked portion 44 is positioned downward. The water stop rubber 42 may be brought into close contact with the stepped surface 111 by pressing it downward. Moreover, the hooked portion 44 is not limited to this example, and may be coupled (fixed) to the protruding portion 32b, for example.

Although the embodiments and modifications of the present invention have been illustrated above, the above-described embodiments and modifications are examples and are not intended to limit the scope of the invention. The above embodiments and modifications can be implemented in various other forms, and various omissions, replacements, combinations, and modifications can be made without departing from the scope of the invention. In addition, specifications such as each configuration and shape (structure, type, direction, format, size, length, width, thickness, height, number, arrangement, position, material, etc.) may be changed as appropriate. can be implemented.

For example, the driving device is not limited to a winding device having a winding shaft or the like for driving the shutter curtain to be wound. The driving device according to the drive type of the shutter curtain can be variously changed, such as a separating and polymerizing device having the shutter curtain, and a feeding device having a driving mechanism for feeding and driving. In addition, the inside of the housing portion includes the inside of the shutter case installed so as to surround the shutter curtain and the driving device in whole or in part, and the space portion where the shutter curtain is accommodated simply when the shutter curtain is opened without a shutter case. include.
