Description

The present disclosure relates to a shutter with a water blocking plate.

Conventionally, a shutter with a water stop plate in which a water stop plate is provided under the shutter is known (see, for example, Patent Document 1).

Japanese Unexamined Patent Publication No. 2007-217991

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 resting on the water stop plate bends in a buckled state when closed. In some cases.

Therefore, one of the problems of the present disclosure is to stop the new configuration which has been improved so as to reduce the inconvenience such that the bending of the shutter curtain located on the water blocking plate at the time of closing can be further reduced. To get a shutter with a water plate.

The shutter with a water blocking plate of the present disclosure is, for example, a shutter curtain that can be moved in the vertical direction and a shutter curtain that is located below the shutter curtain and can be moved in the vertical direction in conjunction with the shutter curtain. It has a water stop plate that suppresses water ingress from the building opening in a closed state in contact with the surface, a first part connected to the shutter curtain, and a second part connected to the water stop plate. In the open state where the water stop plate is separated from the installation surface, the shutter curtain is in a suspended state in which the water stop plate is suspended via the first portion and the second portion, and in the closed state, the shutter is suspended. A suspension mechanism is provided, which is in a released state in which the suspension of the water stop plate via the first portion and the second portion by the curtain is released. According to such a configuration, for example, in the closed state, the hanging state of the water stop plate via the first portion and the second portion by the shutter curtain is released in the hanging mechanism, so that the shutter curtain is released in the closed state. Can be prevented from bending by being placed on the water stop plate.

Further, in the shutter with a water blocking plate, for example, the first portion has a hanging lower portion, and the second portion is in contact with the hanging lower portion in the open state and is in the closed state. It has a suspended lower part that is separated upward from the suspended lower part. According to such a configuration, for example, the suspension mechanism can be realized by a relatively simple configuration.

Further, the shutter with a water stop plate is interposed between the shutter curtain and the water stop plate in a state where the distance between the lower end of the shutter curtain and the installation surface is not more than a predetermined distance in the closed state, for example. A transmission member having a transmission portion for transmitting the load from the shutter curtain to the water stop plate is provided. According to such a configuration, a load from the shutter curtain, such as the weight of the shutter curtain, can be transmitted to the water stop plate via the transmission member, whereby, for example, the water stop plate and the installation surface. It is possible to further enhance the sealing property between and.

Further, in the shutter with a water stop plate, for example, one of the first portion and the second portion includes the transmission portion. According to such a configuration, for example, the configuration can be further simplified or miniaturized as compared with a configuration in which the first portion or the second portion and the transmission portion are separately provided.

Further, in the shutter with a water blocking plate, for example, at least a part of the transmission portion is elastically bent in a state of being convex or concave in a direction intersecting the vertical direction due to a load from the shutter curtain. According to such a configuration, for example, the bending of the shutter curtain can be suppressed by the elastic bending of the transmission portion.

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

Further, in the shutter with a water blocking plate, for example, each of the transmission members has a bent portion and has a plurality of plate-shaped members stacked on each other in the thickness direction. According to such a configuration, for example, in the bent portion, the radius of curvature of the bent portion can be made smaller than that in the configuration in which a thicker plate-shaped member is bent, and the transmission member and thus the water stop can be stopped. The shutter with a plate can be made smaller.

Further, in the shutter with a water blocking plate, for example, the transmission member is overlapped with a plurality of first plate-shaped members arranged in the width direction of the building opening and the indoor side of the first plate-shaped member, respectively, and has the width. It has a plurality of second plate-shaped members arranged in a direction, and the first plate-shaped member and the second plate-shaped member are overlapped with each other in the width direction. According to such a configuration, for example, light leaks 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. It can be suppressed.

According to the present disclosure, it is possible to obtain a shutter with a water stop plate having a novel configuration improved so as to reduce inconvenience.

Here, the operation of the connection mechanism 300 will be described with reference to FIGS. 4 to 7. 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 the connection mechanism 300, the top wall 320a of the second member 320 is in contact with the shaft 314 of the first member 310. Therefore, the connection mechanism 300 is an example of a hanging mechanism, the shaft 314 is an example of a hanging lower portion, and the top wall 320a is an example of a suspended lower 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 move up and down as much as the water stop plate 120 comes into contact with the installation surface 1a as compared with the open state of FIG. As it approaches the direction, in the connection mechanism 300, the top wall 320a of the second member 320 is separated from the shaft 314 of the first member 310. 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 downward from FIG. 5, and the distance between the lower end 110a of the shutter curtain 110 and the installation surface 1a is shorter than the distance in the case of FIG. Along with this, the top wall 320a of the second member 320 is in contact with the top wall 310a of the first member 310. In this case, the load from the shutter curtain 110 is transmitted to the water stop plate 120 via the second member 320. Therefore, the second member 320 is an example of a transmission member. Further, in this case, the load from the shutter curtain 110 is transmitted to the water stop plate 120 via the top wall 320a, the standing wall 320b, and the bottom wall 320c. Therefore, the top wall 320a, the standing wall 320b, and the bottom wall 320c are examples of transmission sites. The state of the connection mechanism 300 shown in FIG. 6 is referred to as a transmission state, a weighted state, a transmission start state, a weighted start state, or the like.

The contact between the top wall 310a of the first member 310 and the top wall 320a of the second member 320 as shown in FIG. 6 causes the shutter curtain 110 to descend while the water stop plate 120 is in the closed position Pc. 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 of FIG. .. The distance Lth is an example of a predetermined distance and is also called a threshold value.

Further, in the state shown in FIG. 7 in which the shutter curtain 110 is further lowered than in FIG. 6, the standing wall 320b of the second member 320 receives a downward load from the shutter curtain 110 and an upward load from the water stop plate 120. It bends under the reaction force and bends in a convex or concave state in the indoor or outdoor direction, in other words, it is buckled. Further, on the shutter 100, a stopper that limits the relative proximity of the shutter curtain 110 and the water stop plate 120 by a predetermined distance or more so that the deformation of the vertical wall 320b in this case is not a plastic deformation but an elastic deformation. A mechanism 400 is provided. Specifically, for example, the lower end 310f of the first member 310 and the tip of the standing wall 121f of the water blocking plate 120 overlap in the vertical direction, and the shutter is caused by the interference between the end 310f and the standing wall 121f. It is configured to limit the downward displacement of the curtain 110. Therefore, the end portion 310f and the standing wall 121f are examples of the stopper mechanism 400 that limits the downward displacement of the shutter curtain 110, the end portion 310f is an example of the first stopper provided on the shutter curtain 110, and the standing wall 121f is an example. This is an example of a second stopper provided on the water stop plate 120. Further, the vertical wall 320b of the second member 320 is an example of an extension portion. The state of the connection mechanism 300 shown in FIG. 7 is referred to as a transmission state, a bending state, or the like.

Further, FIG. 8 is a front view of the second member 320. As shown in FIG. 7, the second member 320 has a plurality of outer plates 321 arranged in the width direction and a plurality of inner plates 322 arranged in the width direction. As is clear from FIG. 7, the outer plate 321 and the inner plate 322 are offset from each other in the width direction and overlap each other. As a result, the boundary B1 between the outer plates 321 adjacent to each other is covered by the inner plate 322, and the boundary B2 between the inner plates 322 adjacent to each other is covered by the outer plate 321. The outer plate 321 is an example of a first plate-shaped member, and the inner plate 322 is an example of a second plate-shaped member.

As described above, in the present embodiment, the connection mechanism 300 (suspension mechanism) has a first member 310 (first part) and a second member 320 (second part), and the water stop plate 120. In the open state (FIG. 4) separated from the installation surface 1a, 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 on the installation surface. In the closed state (FIGS. 5 to 7) in contact with 1a, the suspension 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, the shutter curtain 110 releases the suspended state of the water stop plate 120 via the first member 310 and the second member 320, so that the connection mechanism 300 is closed. In the state, the shutter curtain 110 can be prevented from bending by being placed on the water stop plate 120.

Further, in the present embodiment, for example, the first member 310 has a shaft 314 (suspended lower portion), and the second member 320 is in contact with the shaft 314 in the open state and the shaft 314 in the closed state. It has a top wall 320a (hanging lower part) that is separated upward from the top wall 320a. According to such a configuration, for example, the suspension mechanism can be realized by a relatively simple configuration. The configuration of the suspended lower portion and the suspended lower portion is not limited to this.

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

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

Further, in the present embodiment, for example, the vertical wall 310b (at least a part of the transmission portion) elastically bends in a state of being convex or concave in a direction intersecting the vertical direction due to a 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 vertical wall 310b.

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

Further, in the present embodiment, for example, the second member 320 has a bent portion 320d, and the outer plates 321 (first plate-shaped member, one of a plurality of plate-shaped members) are stacked on each other in the thickness direction. ) And an inner plate 322 (second plate-shaped member, one of a plurality of plate-shaped members). According to such a configuration, for example, in the bent portion 320d, the radius of curvature of the bent portion 320d can be made smaller than that in the configuration in which one thicker plate-shaped member is bent, and the second member. The 320 and thus the shutter 100 (shutter with a water blocking plate) can be further miniaturized. Further, by forming the first member 310 or the second member 320 by press molding or bending molding of a plate-shaped member, the manufacturing cost and labor can be easily reduced.

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

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

For example, the transmission member may be provided on the first member. Further, the member constituting the first portion and the member constituting the second portion may be composed of one member.
