2. Description of the Related Art Conventionally, a shutter with a water stop provided with a water stop under the shutter is known (see, for example, Patent Document 1).

JP-A-2007-217993

In this type of shutter with a water stop plate, for example, when the lower end of the shutter curtain is fixed to the water stop plate, the shutter curtain on the water stop plate bends in a buckled state when the shutter is closed. Sometimes.

Therefore, one of the problems of the present disclosure is to provide a novel stop structure that is improved to be less inconvenient, for example, to further reduce deflection of the shutter curtain positioned above the water stop plate when closed. It is to get a shutter with a water plate.

The shutter with a water stop plate of the present disclosure is, for example, a vertically movable shutter curtain, is positioned below the shutter curtain, is vertically movable in conjunction with the shutter curtain, and is installed in a building opening. a water stop plate that prevents water ingress from the opening of the building in the closed state in contact with the surface; a transmission member interposed between the water stop plate and having a transmission portion for transmitting the load from the shutter curtain to the water stop plate; a first portion connected to the shutter curtain; and a connected second portion, wherein the shutter curtain suspends the waterstop through the first portion and the second portion in an open state in which the waterstop is separated from the installation surface. a suspension mechanism that is in a suspended state, and is in a released state in which suspension of the water stop plate via the first portion and the second portion by the shutter curtain is released in the closed state. According to such a configuration, for example, in the closed state, in the suspension mechanism, the suspended state of the water stop plate via the first portion and the second portion by the shutter curtain is released. It is possible to suppress bending by placing on the water stop plate. In addition, the transmission portion elastically bends into a convex or concave shape in a direction intersecting the vertical direction due to the load from the shutter curtain. can do. In addition, the load from the shutter curtain, such as the weight of the shutter curtain itself, can be transmitted to the water stop plate via the transmission member. can be enhanced.
In addition, the shutter with a waterstop includes, for example, a stopper mechanism that restricts the relative proximity of the shutter curtain and the waterstop over a predetermined distance or more. By providing a stopper mechanism composed of an end portion and an upper end portion of the water stop plate, for example, downward displacement of the shutter curtain can be restricted.
Further, in the shutter with a water stop plate, for example, the second portion includes a ceiling wall, a standing wall extending downward from an end of the ceiling wall, and an elongated hole formed through the standing wall and extending in the vertical direction. .

Further, in the shutter with a water stop plate, for example, the first portion has a suspension portion, and the second portion is in contact with the suspension portion in the open state and is in contact with the suspension portion in the closed state. It has a suspended portion spaced upward from the suspended portion. With such a configuration, for example, the suspension mechanism can be realized with a relatively simple configuration.

Further, in the shutter with a water stop plate, for example, one of the first portion and the second portion includes the transmission portion. With such a configuration, for example, the configuration can be simplified and the size can be reduced more compared to a configuration in which the first part or the second part and the transmission part are provided separately.

Further, in the water stop plate-equipped shutter, for example, the transmission member includes an extending portion having a plate-like shape extending in the vertical direction. With such a configuration, for example, the extension can be a transmission portion that elastically bends due to the load received from the shutter curtain, and the transmission member can be realized with a relatively simple configuration.

Further, in the shutter with a water stop plate, for example, the transmission member has a plurality of plate-like members each having a bent portion and stacked in the thickness direction. According to such a configuration, for example, compared to a configuration in which a thick plate-shaped member is bent at the bent portion, the curvature radius of the bent portion can be made smaller, and the transmission member and thus the water stop can be reduced. The plate-equipped shutter can be made more compact.

Further, in the shutter with water stop plate, for example, the transmission member includes a plurality of first plate-like members arranged in the width direction of the building opening, and the first plate-like members each superimposed on the indoor side of the first plate-like member. and a plurality of second plate-like members aligned in the direction, wherein the first plate-like member and the second plate-like member overlap with each other while being displaced from each other in the width direction. According to such a configuration, for example, leakage of light from the boundary between two first plate-shaped members adjacent to each other in the width direction and the boundary between two second plate-shaped members adjacent to each other in the width direction can be suppressed.

According to the present disclosure, it is possible to obtain a water stop plate-equipped shutter with a novel configuration that is improved to reduce inconvenience.

The operation of connection mechanism 300 will now be described with reference to FIGS. In the open state shown in FIG. 4, the shutter curtain 110 suspends the water stop plate 120 via the connection mechanism 300 (suspended state). In connection mechanism 300 , top wall 320 a of second member 320 is in contact with shaft 314 of first member 310 . Therefore, the connection mechanism 300 is an example of a suspension mechanism, the shaft 314 is an example of a suspended portion, and the ceiling wall 320a is an example of a suspended portion.

In the closed state shown in FIG. 5, the lower end 110a of the shutter curtain 110 and the top surface 120e of the water stop plate 120 are raised or lowered as compared to the open state of FIG. As a result, the top wall 320a of the second member 320 is separated from the shaft 314 of the first member 310 in the connection mechanism 300. As shown in FIG. In this case, the suspended state of the water stop plate 120 via the connection mechanism 300 by the shutter curtain 110 is released (released state).

In the closed state shown in FIG. 6, the shutter curtain 110 moves lower than in FIG. 5, and the distance between the lower end 110a of the shutter curtain 110 and the installation surface 1a is shorter than in FIG. Accordingly, the top wall 320a of the second member 320 is in contact with the bottom of the top wall 310a of the first member 310. As shown in FIG. In this case, the load from shutter curtain 110 is transmitted to water stop plate 120 via second member 320 . Therefore, the second member 320 is an example of a transmission member. Also, in this case, the load from the shutter curtain 110 is transmitted to the water stop plate 120 via the ceiling wall 320a, the vertical wall 320b, and the bottom wall 320c.

The contact between the ceiling wall 310a of the first member 310 and the ceiling wall 320a of the second member 320 as shown in FIG. Along with this, it occurs when the vertical gap G shown in FIG. 5 disappears. Therefore, the second member 320 functions as a transmission member when the distance between the lower end 110a of the shutter curtain 110 and the installation surface 1a (not shown in FIG. 6) is equal to or less than the distance Lth in the state shown in FIG. . The distance Lth is an example of a predetermined distance and is also called a threshold.

7, in which the shutter curtain 110 is further lowered than in FIG. It bends by receiving a reaction force, and is bent in a convex or concave state in the indoor direction or the outdoor direction, in other words, it is buckled. Further, the shutter 100 is provided with a stopper that restricts the relative proximity of the shutter curtain 110 and the water stop plate 120 beyond a predetermined distance so that the deformation of the vertical wall 320b in this case is not plastic deformation but elastic deformation. A mechanism 400 is provided. Specifically, for example, the lower end portion 310f of the first member 310 and the tip of the vertical wall 121f of the water stop plate 120 overlap in the vertical direction, and interference between the end portion 310f and the vertical wall 121f causes the shutter to It is configured such that downward displacement of the curtain 110 is limited. Therefore, the end portion 310f and the standing wall 121f are an example of a stopper mechanism 400 that limits the downward displacement of the shutter curtain 110, the end portion 310f is an example of a first stopper provided on the shutter curtain 110, and the standing wall 121f is , is an example of a second stopper provided on the water stop plate 120. FIG. Also, the standing wall 320b of the second member 320 is an example of an extension. The state of the connection mechanism 300 shown in FIG. 7 is called a transmission state, a deflection state, or the like.

8 is a front view of the second member 320. FIG. As shown in FIG. 7, the second member 320 has a plurality of outer plates 321 aligned in the width direction and a plurality of inner plates 322 aligned in the width direction. As is clear from FIG. 7, the outer plate 321 and the inner plate 322 overlap with each other while shifting in the width direction. Accordingly, the boundary B1 between the outer plates 321 adjacent to each other is covered with the inner plate 322, and the boundary B2 between the inner plates 322 adjacent to each other is covered with the outer plate 321. The outer plate 321 is an example of a first plate member, and the inner plate 322 is an example of a second plate member.

As described above, in the present embodiment, the connection mechanism 300 (suspension mechanism) has the first member 310 (first portion) and the second member 320 (second portion). is separated from the installation surface 1a (FIG. 4), the shutter curtain 110 is in a suspended state in which the water stop plate 120 is suspended via the first member 310 and the second member 320, and the water stop plate 120 is placed on the installation surface. In the closed state (FIGS. 5 to 7) in contact with 1a, the suspended state of the water stop plate 120 via the first member 310 and the second member 320 by the shutter curtain 110 is released. According to such a configuration, for example, in the closed state, in the connection mechanism 300, the suspended state of the water stop plate 120 via the first member 310 and the second member 320 by the shutter curtain 110 is released. In this state, the shutter curtain 110 is placed on the water stop plate 120 to prevent the shutter curtain 110 from bending.

Further, in this embodiment, for example, the first member 310 has a shaft 314 (suspended portion), and the second member 320 is in contact with the shaft 314 in the open state and is in contact with the shaft 314 in the closed state. It has a ceiling wall 320a (suspended part) spaced upward from. With such a configuration, for example, the suspension mechanism can be realized with a relatively simple configuration. In addition, the structure of a suspended part and a suspended part is not limited to this.

Further, in the present embodiment, for example, the second member 320 (transmission member) is in a state in which the distance between the lower end 110a of the shutter curtain 110 and the installation surface 1a in the closed state is equal to or less than the distance Lth (predetermined distance, see FIG. 6). 6 and 7 , it is interposed between the shutter curtain 110 and the water stop plate 120 to transmit the load from the shutter curtain 110 to the water stop plate 120 . With such a configuration, for example, the load from the shutter curtain 110, such as the weight of the shutter curtain 110 itself, can be transmitted to the water stop plate 120 via the second member 320. The surface pressure of the sealing member between the water plate 120 and the installation surface 1a is increased, and the sealing performance of the sealing member can be further enhanced.

Further, in the present embodiment, for example, the second member 320 (one portion) includes a top wall 320a, an upright wall 320b, and a bottom wall 320c (transmission portion). According to such a configuration, for example, compared to a configuration in which the first member 310, the second member 320, and the transmission parts are provided separately, the configuration can be simplified and the size can be further reduced.

Further, in this embodiment, for example, the upright wall 310b (at least part of the transmission part) is elastically bent in a convex or concave state in a direction intersecting the vertical direction due to the load from the shutter curtain 110 . According to such a configuration, for example, the bending of the shutter curtain 110 can be suppressed by the elastic bending of the standing wall 310b.

Further, in the present embodiment, for example, the second member 320 includes a vertical wall 320b (extending portion) having a plate-like shape extending in the vertical direction. With such a configuration, for example, the vertical wall 320b can be used as a transmission portion that elastically bends due to the load received from the shutter curtain 110, and the transmission member can be realized with a relatively simple configuration.

Further, in the present embodiment, for example, the second member 320 includes outer plates 321 (first plate-like member, one of a plurality of plate-like members) which have bending portions 320d and are stacked on each other in the thickness direction. ) and an inner plate 322 (second plate member, one of the plurality of plate members). According to such a configuration, for example, in the bent portion 320d, compared to a configuration in which a thicker plate-shaped member is bent, the radius of curvature of the bent portion 320d can be made smaller, and the second member 320 and eventually the shutter 100 (shutter with a water stop plate) can be made smaller. In addition, manufacturing the first member 310 or the second member 320 by press-molding or bending a plate-like member can reduce manufacturing costs and labor.

Further, in this embodiment, for example, the outer plate 321 and the inner plate 322 are overlapped in the thickness direction (indoor direction or outdoor direction) while being displaced from each other in the width direction. According to such a configuration, for example, leakage of light from both the boundary B1 of the two outer plates 321 adjacent to each other in the width direction and the boundary B2 of the two inner plates 322 adjacent to each other in the width direction can be prevented. can be suppressed.

Although the embodiment of the present invention has been illustrated above, the above embodiment is an example and is not intended to limit the scope of the invention. The above embodiments 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 transmission member may be provided on the first member. Also, the member forming the first portion and the member forming the second portion may be formed by one member.
