Description

The present invention relates to a shutter with a water stop plate and a method for setting the lower limit position of a shutter with a water stop plate.

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

Japanese Patent Application Publication No. 2013-159911

With this type of shutter with a water stop plate, for example, if the lower limit position at closing shifts upward due to repeated opening and closing operations, the water stop plate may become separated from the installation surface of the building opening and the water stop performance may deteriorate. was there.

Therefore, one of the objects of the present invention is, for example, to obtain a shutter with a water stop plate and a method for setting the lower limit position of the shutter with a water stop plate, which has a new configuration with fewer inconveniences.

The shutter with a water stop plate of the present invention includes, for example, a shutter curtain that opens and closes a building opening by moving in the vertical direction, and a shutter that is located below the shutter curtain and is movable in the vertical direction in conjunction with the shutter curtain. a water stop plate that is in contact with an installation surface of the building opening and suppresses water intrusion from the building opening in a closed state; a first member connected to the shutter curtain; and a first member connected to the water stop plate. and two members, and in an open state where the water stop plate is spaced from the installation surface, the shutter curtain is in a suspended state in which the water stop plate is suspended through the first member and the second member. , a suspension mechanism in which the water stop plate is in a released state in which suspension of the water stop plate via the first member and the second member by the shutter curtain is released in the closed state; and the released state of the water stop plate. and an indicator indicating a lower limit position at.

According to such a configuration, for example, by using the instruction section, it is easy to reduce the amount of effort required by an operator to set (adjust) the lower limit position of the shutter with a water stop plate. Further, for example, a shift in the lower limit position is more easily tolerated than in a case where the lower limit position of the water stop plate in the suspended state is indicated on the indicator. As a result, for example, even if the lower limit position when closing a shutter with a water stop plate shifts upward due to repeated opening and closing operations, the water stop plate will move away from the installation surface and the water stop performance will deteriorate. Less likely to cause any inconvenience.

Further, in the shutter with a water stop plate, for example, the first member has a hanging part, and the second member is in contact with the hanging part in the open state and in the closed state. It has a suspended part that is spaced apart upward from the suspended part, and the indicator indicates at least a position where the suspended part is spaced apart from the suspended part as the lower limit position. According to such a configuration, for example, the hanging mechanism and the instruction section can be realized with a relatively simple configuration.

Further, in the shutter with a water stop plate, for example, the second member contacts the first member in a state where the distance between the lower end of the shutter curtain and the installation surface is a predetermined distance or less in the closed state, The indicator indicates, as the lower limit position, a position at which a load from the shutter curtain is transmitted to the water stop plate via the second member. According to such a configuration, for example, by referring to the instruction section, it is possible to grasp the starting position at which the load from the shutter curtain, such as the weight of the shutter curtain, is transmitted to the water stop plate via the second member. I can do it. For example, the operator pushes the water stop plate into the installation surface via the first member and the second member by setting the lower limit position of the shutter curtain while visually checking the positional relationship between the indicator and the first member. be able to. As a result, for example, the surface pressure of the seal member between the water stop plate and the installation surface increases, and the sealing performance of the seal member can be further improved. In addition, for example, even if the position for pushing the water stop plate into the installation surface shifts upward due to the weight of the shutter curtain due to long-term use, the surface of the sealing member between the water stop plate and the installation surface may It is possible to tolerate and adjust the shift in the lower limit position of the shutter curtain while maintaining the pressure.

Further, in the shutter with a water stop plate, for example, the instruction section has a reference display provided on the second member and aligned with a lower end of the first member at the lower limit position. According to such a configuration, for example, by using the reference display, it is easy to reduce the amount of effort required by an operator to set (adjust) the lower limit position of the shutter with a water stop plate. Further, for example, the reference display can prevent the lower limit position from being set at a position beyond the position where the load from the shutter curtain is transmitted to the water stop plate via the second member. As a result, for example, at the lower limit position, it is possible to prevent the surface pressure of the sealing member between the water stop plate and the installation surface from increasing too much, and from bending the shutter curtain.

Further, the method for setting the lower limit position of the shutter with a water stop plate of the present invention includes, for example, a step of lowering the shutter with a water stop plate so that the water stop plate is in a released state in which suspension of the water stop plate is released; adjusting the position of the shutter with a water stop plate so that the lower end of the first member overlaps with the reference display of the indicator; The method includes a step of setting a lower limit position of a shutter with a water plate. According to such a configuration, for example, the effort required by an operator to set (adjust) the lower limit position of the shutter with a water stop plate is likely to be reduced.

According to the present invention, it is possible to obtain a shutter with a water stop plate and a method for setting the lower limit position of the shutter with a water stop plate, which have a novel configuration with fewer inconveniences.

Here, the operation of the hanging mechanism 300 will be explained with reference to FIGS. 4 to 6. In the open state shown in FIG. 4, the shutter curtain 110 suspends the water stop plate 120 via the suspension mechanism 300 (suspended state). Specifically, in the suspension mechanism 300, the top wall 320a of the second member 320 is in contact with the top of the shaft 314 of the first member 310. Therefore, the shaft 314 is an example of a suspended portion, and the ceiling wall 320a is an example of a suspended portion. Note that the suspension mechanism 300 is not limited to the example using the shaft 314 and the elongated hole 320e, and may suspend the water stop plate 120 using a chain, a link mechanism, or the like, for example.

In the closed state shown in FIG. 5, the lower end 110a of the shutter curtain 110 and the top surface of the water stop plate 120 are in contact with the lower end 110a of the shutter curtain 110 and the top surface of the water stop plate 120 compared to the open state shown in FIG. 120e approach each other in the Z direction, and accordingly, in the suspension mechanism 300, the top wall 320a of the second member 320 is spaced upward from the shaft 314 of the first member 310.

In this case, the suspension state of the water stop plate 120 via the suspension mechanism 300 by the shutter curtain 110 is released (released state). Therefore, the seal member below the water stop plate 120 is elastically compressed by the load from the water stop plate 120, such as its own weight, and generates surface pressure. This surface pressure improves the sealing performance between the installation surface 1a and the water stop plate 120.

In the closed state shown in FIG. 6, the shutter curtain 110 moves further downward than in FIG. 5, and the distance Lth 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. . 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.

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 sealing member below the water stop plate 120 is elastically compressed by the load from the shutter curtain 110, and the sealing performance between the installation surface 1a and the water stop plate 120 is further improved. The second member 320 is an example of a transmission member. The states of the hanging mechanism 300 shown in FIG. 6 are referred to as a transmission state, a load state, a transmission start state, a load start state, and 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. Accordingly, this occurs when the gap in the Z direction 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 is less than or equal to the distance Lth in the state shown in FIG. The distance Lth is an example of a predetermined distance, and is also referred to as a threshold value.

As shown in FIGS. 7 to 9, an instruction sticker 150 is provided at the end of the second member 320 in the Y direction, that is, the end on the switch box 230 side (see FIG. 1). On the instruction sticker 150, for example, a boundary line 153 indicating the lower limit position of the shutter 100, an arrow 152, characters 151, etc. are drawn. The instruction sticker 150 is an example of an instruction section.

The instruction sticker 150 is attached, for example, to the rear surface of the vertical wall 320b of the second member 320 on the indoor side. A first region 150a above the boundary line 153 and a second region 150b below the boundary line 153 of the instruction sticker 150 have different colors. The boundary line 153 is an example of a reference display.

Note that the reference display is not limited to the example of color-coding areas such as the boundary line 153, but can also be used to indicate the reference position or border, such as a drawn line, groove, protrusion, step, picture, pattern, mark, etc. It can be anything as long as it represents something. Further, the reference display is not limited to one that represents one position or one boundary, but may represent the position or boundary in stages in the moving direction of the shutter curtain 110.

Further, in this embodiment, a case is taken as an example in which the instruction sticker 150 is installed on the rear surface of the vertical wall 320b of the second member 320 on the indoor side. By installing the instruction sticker 150 indoors in this manner, it is possible to reduce deterioration of the instruction sticker 150 due to dirt, tampering, and ultraviolet rays. On the other hand, the instruction sticker 150 may be installed on the outdoor side of the vertical wall 320b of the second member 320, if necessary.

Characters 151, arrows 152, etc. are provided in the first region 150a. Arrow 152 is located below character 151. In other words, arrow 152 is located between character 151 and border line 153. Arrow 152 is configured as a downward arrow pointing to boundary line 153.

In this embodiment, in the open state shown in FIG. 7, the instruction sticker 150 is exposed indoors from the lower end 310f of the first member 310. In other words, the characters 151, the arrow 152, and the boundary line 153 of the instruction sticker 150 are located below the end portion 310f.

Further, in the closed state shown in FIG. 8, the first member 310 overlaps a part of the instruction sticker 150 in the X direction as the first member 310 has moved downward relative to the second member 320. Specifically, at least a portion of the characters 151 of the instruction sticker 150 are hidden by the rear wall 310d of the first member 310.

Furthermore, in the closed state shown in FIG. 9, the first member 310 has moved downward relative to the second member 320 compared to FIG. They overlap in the X direction. In other words, the characters 151 and arrow 152 of the instruction sticker 150 are hidden by the rear wall 310d of the first member 310.

In this embodiment, the end portion 310f shown in FIG. 9 and the boundary line 153 overlap, in other words, the load from the shutter curtain 110 shown in FIG. The lower limit position of the shutter 100 is set at the position transmitted to the plate 120. Thereby, for example, the surface pressure of the sealing member between the water stop plate 120 and the installation surface 1a is likely to increase, and as a result, the sealing performance between the water stop plate 120 and the installation surface 1a can be further improved.

Further, for example, even if the lower limit position shifts upward due to repeated opening and closing operations of the shutter 100, the shift in the Z direction is allowed by the first region 150a above the boundary line 153, and as a result, the water stop plate 120 It is possible to suppress the water stop performance from decreasing due to separation from the installation surface 1a. In this way, the instruction sticker 150 indicates the lower limit position of the water stop plate 120 in the released state.

For example, when the shutter curtain 110 is lowered further than in FIGS. 6 and 9, the upward reaction force from the second member 320 and the waterstop plate 120 due to the downward load from the shutter curtain 110 is The shutter curtain 110 is joined to the shutter curtain 110, and the shutter curtain 110 is bent. The shutter curtain 110 in the bent state absorbs the reaction force by each slat and the connecting portion between the slats, and uses its own weight to move the waterstop plate 120 to the installation surface via the first member 310 and the second member 320. It can be pushed into 1a.

FIG. 10 is a front view of the second member 320 of FIG. 4. As shown in FIG. 10, the second member 320 includes, for example, a plurality of outer plates 321 arranged in the Y direction and a plurality of inner plates 322 arranged in the Y direction. As is clear from FIG. 10, the outer plate 321 and the inner plate 322 overlap with each other and are shifted from each other in the Y direction.

In this embodiment, with such a configuration, the boundary B1 between mutually adjacent outer plates 321 is covered by the inner plate 322, and the boundary B2 between mutually adjacent inner plates 322 is covered by the outer plate 321. There is. Thereby, for example, leakage of light from both the boundary B1 of the outer plate 321 and the boundary B2 of the inner plate 322 is suppressed.

Next, an example of a method for setting the lower limit position of the shutter 100 will be described. First, the operator lowers the shutter 100 so that the suspension of the water stop plate 120 is released (S1). S1 is an example of the first step.

Next, the operator adjusts the position of the shutter 100 so that the lower end 310f of the first member 310 overlaps the boundary line 153 of the instruction sticker 150 (S2). S2 is an example of the second step.

Next, with the end 310f of the first member 310 and the boundary line 153 overlapping, the operator moves the shutter 100 to the lower limit position using a control limit switch provided in the switch box 230 or the winding device 220. (S3). S3 is an example of the third step.

As described above, in the present embodiment, for example, when the shutter 100 is in the open state (FIG. 4) in which the water stop plate 120 is spaced apart from the installation surface 1a, the shutter curtain 110 is In the closed state (FIGS. 5 and 6) in which the water stop plate 120 is suspended and the water stop plate 120 is in contact with the installation surface 1a, the shutter curtain 110 is in a suspended state through the first member 310 and the second member 320. It includes a hanging mechanism 300 that is in a released state in which the suspension of the water stop plate 120 is released, and an instruction sticker 150 (instruction part) that indicates the lower limit position of the water stop plate 120 in the released state.

According to such a configuration, for example, by using the instruction sticker 150, the effort required by the operator to set (adjust) the lower limit position of the shutter 100 is likely to be reduced. Further, for example, compared to a case where the instruction sticker 150 indicates the lower limit position of the water stop plate 120 in the suspended state, a shift in the lower limit position is more easily tolerated. As a result, for example, even if the lower limit position at the time of closing shifts upward due to repeated opening and closing operations of the shutter 100, the water stop plate 120 is separated from the installation surface 1a, resulting in an inconvenience such as a decrease in water stop performance. is unlikely to occur.

In the present embodiment, for example, the instruction seal 150 indicates that at least the top wall 320a (suspended portion) of the second member 320 starts to separate upward from the shaft 314 (suspended portion) of the first member 310 as the lower limit position. Indicates the reference position. According to such a configuration, for example, the hanging mechanism 300 and the instruction seal 150 can be realized with a relatively simple configuration.

Further, in this embodiment, for example, the instruction sticker 150 indicates a position where the load from the shutter curtain 110 starts to be transmitted to the water stop plate 120 via the second member 320 as the lower limit position. According to such a configuration, for example, the instruction sticker 150 indicates that the load from the shutter curtain 110, such as the weight of the shutter curtain 110, starts to be transmitted to the water stop plate 120 via the second member 320 as a reference. If necessary, the position where the shutter curtain 110 is pushed further downward can be set as the lower limit position.

That is, by referring to the instruction sticker 150, it is possible to grasp the reference position at which the load (self-weight) from the shutter curtain 110 is transmitted to the waterstop plate 120 via the second member 320. For example, by setting the lower limit position of the shutter curtain 110 while visually checking the positional relationship between the instruction sticker 150 and the first member 310, the operator can install the water stop plate via the first member 310 and the second member 320. 120 can be pushed into the installation surface 1a. As a result, for example, the surface pressure of the seal member between the water stop plate 120 and the installation surface 1a increases, and the sealing performance of the seal member can be further improved. For example, even if the position for pushing the water stop plate 120 into the installation surface 1a shifts upward due to the weight of the shutter curtain 110 due to long-term use, the gap between the water stop plate 120 and the installation surface 1a It is possible to allow and adjust the shift of the lower limit position of the shutter curtain 110 while maintaining the surface pressure of the sealing member.

Further, in this embodiment, for example, the instruction sticker 150 is provided on the second member 320 and has a boundary line 153 (reference display) that is aligned with the lower end 310f of the first member 310 at the lower limit position. According to such a configuration, by using the boundary line 153, the effort required by the operator to set (adjust) the lower limit position of the shutter 100 can be easily reduced. Further, for example, it is possible to prevent the lower limit position from being set at a position beyond the position where the load from the shutter curtain 110 is transmitted to the waterstop plate 120 via the second member 320 due to the boundary line 153. As a result, for example, at the lower limit position, it is possible to prevent the surface pressure of the seal member between the water stop plate 120 and the installation surface 1a from increasing too much, and to prevent the shutter curtain 110 from bending.

In addition, in the present embodiment, for example, the method for setting the lower limit position of the shutter 100 includes a step of lowering the shutter 100 and lowering the first member 310 so that the suspension of the water stop plate 120 is released. a step of adjusting the position of the shutter 100 so that the end portion 310f overlaps with the boundary line 153 of the instruction sticker 150; and a step of setting the lower limit position of the shutter 100 with the end portion 310f and the boundary line 153 overlapping each other. , has. According to such a configuration, for example, the effort required by an operator to set (adjust) the lower limit position of the shutter 100 is likely to be reduced.
