[0022] The embodiments of the present invention will be described in detail below with reference to the drawings. Note that the following embodiments are merely examples of how the present invention can be implemented, and do not limit the present invention to their scope.

[0023] <Embodiment 1> Figures 1 and 2 are schematic diagrams showing the waterproofing device of Embodiment 1 according to the present invention attached to a window shutter. Figure 1(a) is a schematic vertical cross-sectional view with the shutter closed, Figure 1(b) is a schematic vertical cross-sectional view with the shutter open, Figure 1(c) is an enlarged view of the lower part of Figure 1(a), and Figure 2 is a schematic horizontal cross-sectional view. The waterproofing device 1 of this embodiment is a waterproofing device installed on a window shutter (opening and closing device) provided on a sliding window of a house, and includes a water-stopping member that can be attached to a shutter frame (frame body) for installing a shutter curtain (opening and closing body that opens and closes the opening vertically). A sliding window constitutes an "opening in which the lower end of the opening is located higher than the ground," and a window shutter provided on a sliding window is installed in an "opening in which the lower end of the opening is located higher than the ground."

[0024] The window shutter 2 comprises a shutter frame (frame body) having a shutter case 21 located at the top, a vertical frame 22 having guide rails 221 that guide the opening and closing operation (up and down movement) of the shutter curtain S on both sides, and a lower frame 23, and is installed in the sliding window portion such as a sash window provided in an opening formed in the wall of a house (for example, the shutter frame is attached to the sash frame). The shutter case 21 is equipped with a winding mechanism that cancels or reduces the weight of the shutter curtain S by incorporating a spring shaft or the like, allowing it to be wound up. Furthermore, the window shutter itself may be any window shutter having a guide rail for guiding the shutter curtain, and the concept of the waterproofing device of this embodiment can be applied to any conventional window shutter having a guide rail. Therefore, further detailed explanations regarding the winding mechanism and other structures of the window shutter itself are omitted.

[0025] The waterproof device 1 of this embodiment is Water stop plate 11 and A lower sealing member 12 that prevents water from entering between the water-stopping plate 11 and the lower frame 23, Side sealing members 13 are provided on both sides of the water-stopping plate 11 in the width direction (depth direction in Figure 1, left-right direction in Figure 2) to stop water from escaping between the water-stopping plate 11 and the guide rail 221, It is equipped with a guide rail 221 and is installed to stop water from entering the lower part of the window shutter (opening). The basic form of the water-stopping plate 11 is a substantially rectangular member when viewed from the front (when viewed from the left side in Figure 1, and from above in Figure 2), possessing strength to withstand water pressure, and formed from a metal such as aluminum, steel, stainless steel, or a resin such as PVC (a plate or a plate made by connecting extruded material), acrylic plate, or polycarbonate plate. It may also be formed as a hollow panel (or a hollow body filled with a filler such as foamed urethane). The lower sealing member 12 and the side sealing member 13 are continuously provided across both sides and the bottom of the water-stopping plate 11 (they are provided so as to surround it on three sides). The sealing members are preferably waterproof and elastic, and are formed using resins such as soft rubber, foamed rubber, or urethane. Alternatively, a water-expanding material (a material that expands by absorbing water to seal gaps and stop water leakage) may be used.

[0026] The waterproofing device 1 in this embodiment is pre-installed as part of the window shutter 2, and the lower part of the shutter curtain S (opening / closing body) and the upper part of the water-stopping plate 11 are connected, so that the water-stopping plate 11 functions as a base plate for the shutter curtain S. Therefore, as shown in Figure 1(b), when the shutter is raised, the water-stopping plate 11 also moves upward.

[0027] As shown in Figure 2, the water-stopping plate 11 has both ends in the width direction fitted into the guide grooves of the guide rail 221, and the side sealing member 13 seals water between it and the guide rail 221 (a rib-shaped member formed in the guide groove in this embodiment), thereby sealing water at both ends. Furthermore, as shown in Figure 1(c), when the shutter is closed, the lower sealing member 12 comes into contact with the lower frame 23 (in this embodiment, the bottom surface of the groove in the lower frame that receives the lower end of the shutter curtain), thereby sealing the lower part. With these configurations, when the shutter is closed, the lower part of the window shutter (opening) (the area where the water-stopping plate 11 is installed) is sealed off.

[0028] As described above, according to this embodiment, a waterproofing device can be installed for openings where the lower end of the opening is located higher than the ground. The configuration of the window shutter itself can remain the same as conventional ones, and waterproofing measures can be implemented inexpensively and easily without requiring the addition of special mounting parts or other modifications to existing window shutter products. With the increasing severity of flood damage in recent years, the amount of damage caused by flooding above floor level has also increased, and there is a growing need to prevent or reduce such damage. To prevent or reduce flooding above floor level, waterproofing of sliding windows is essential. The waterproofing device 1 of this embodiment is extremely useful because it allows for inexpensive and easy waterproofing of sliding windows equipped with window shutters.

[0029] In this embodiment, the side sealing member is shown in contact with a rib-shaped member formed in the guide groove as an example, but the present invention is not limited to this, and any configuration that can stop water from entering between the guide rail (frame) and the water-stopping plate is acceptable (the member to which the sealing member contacts may be appropriately changed depending on the configuration of the guide rail). Also, in this embodiment, the lower sealing member is shown in contact with the bottom surface of the groove of the lower frame as an example, but the present invention is not limited to this, and any configuration that can stop water from entering between the lower frame (frame) and the water-stopping plate is acceptable (the member to which the sealing member contacts may be appropriately changed depending on the configuration of the lower frame). Furthermore, although this embodiment uses an example where the sealing member is provided on the water-stopping plate side, the sealing member may also be provided on the shutter frame (frame body) side. Figures 3 and 4 show examples of seal members with different configurations.

[0030] Figures 3(a) and 3(b) are schematic vertical cross-sectional views showing the area near the lower frame of the shutter frame. In the example shown in Figure 3(a), the lower sealing member 12' is provided in the groove of the lower frame 23 of the shutter frame, on its bottom surface and on the indoor side wall surface. That is, the lower sealing member 12' has a substantially L-shape in a vertical cross-sectional view. The bottom side of the lower sealing member 12' is conceptually the same as the lower sealing member 12 in Embodiment 1. The side of the lower sealing member 12' is configured to be in contact with the outdoor surface of the structural part of the frame (the indoor side wall of the groove), and when water pressure is applied from the outdoor side during a flood, this water pressure generates a force that presses the water-stopping plate 11 against the shutter frame (i.e., a force that makes the sealing member 12' adhere tightly), thereby improving waterproofing.

[0031] The lower sealing member 12'' in the example of Figure 3(b) is basically the same as the lower sealing member 12'' in the example of Figure 3(a). In the example of Figure 3(b), an inclined surface 232 is formed in the groove of the lower frame 23''. The inclined surface 232 is formed on the outdoor side wall of the groove and is an inclined surface whose projection toward the indoor side increases as it goes downwards. Therefore, as the water-stopping plate 11 descends, it has the function of pressing the water-stopping plate 11 toward the indoor side. As a result, when the shutter is closed, a force is generated that presses the water-stopping plate 11 against the shutter frame (i.e., a force that makes the lower sealing member 12'' tightly adhere), thereby improving waterproofing. Figure 4 is a schematic vertical cross-sectional view showing the vicinity of one side of the vertical frame. The other side has a similar configuration (symmetrical). In the example shown in Figure 4, the side sealing member 13' is provided on the indoor side of both ends of the water-stopping plate 11 and is configured to be in contact with the outdoor surface of the structural part of the frame (the indoor wall of the groove of the guide rail). Furthermore, in the example shown in Figure 4, an inclined surface 222 is formed within the groove of the guide rail of the vertical frame 22'. The inclined surface 222 is formed on the exterior wall surface of the groove of the guide rail and is an inclined surface whose projection toward the interior increases as it moves outward in the width direction, and therefore has the function of pressing the water-stopping plate 11 toward the interior. This generates a force that presses the water-stopping plate 11 against the shutter frame (i.e., a force that makes the side sealing member 13' adhere tightly), thereby improving waterproofing. The inclined surface 232 in the example of Figure 3(b) and the inclined surface 222 in the example of Figure 4 function as a "pressing mechanism that presses the water-stopping plate against the outdoor surface of the structural part of the frame." However, the pressing mechanism of the present invention is not limited to this, and any structure that has the function of "pressing the water-stopping plate against the outdoor surface of the structural part of the frame" (for example, one that uses a biasing member such as an elastic body to press the water-stopping plate against the outdoor surface of the structural part of the frame) can be used.

[0032] In this embodiment, the waterproofing device is pre-integrated as part of the window shutter, and the lower part of the shutter curtain (opening / closing body) is connected to the upper part of the water-stopping plate as an example. However, the present invention is not limited to this, and the waterproofing device described above may be installed on the guide rail retrospectively (as needed when flooding is expected), or the shutter curtain and the water-stopping plate may not be connected. The waterproofing device is retrospectively attached to the guide rails using a back-and-forth method, where one end of the waterproofing device in the width direction is inserted into the groove of one guide rail, and then the other end is inserted into the groove of the other guide rail. The elasticity of the side sealing members improves the workability of this process.

[0033] <Embodiment 2> Figures 5 and 6 are schematic diagrams showing the waterproofing device of Embodiment 2 according to the present invention attached to a window shutter. Figure 5 is a schematic vertical cross-sectional view showing the area near the bottom of the shutter frame, and Figure 6 is a schematic horizontal cross-sectional view. The waterproofing device 1-2 of this embodiment is a waterproofing device installed on a window shutter, similar to Embodiment 1. Although the shape of the window shutter itself differs from that of Embodiment 1, its concept is the same as that of Embodiment 1. Therefore, the same reference numerals are used for components that have the same concept as those in Embodiment 1, and their explanation here is simplified or omitted.

[0034] The waterproofing device 1-2 of this embodiment is installed on the inside of the shutter frame, on the indoor side (right side in Figure 5, lower side in Figure 6). The water-stopping plate 11 of the waterproofing device 1-2 has the same configuration as the water-stopping plate 11 of Embodiment 1, and includes a side sealing member 13 that seals water between the vertical frame 22 and the water-stopping plate 11, and a lower sealing member 12 that seals water between the lower frame 23 and the water-stopping plate 11, and is attached to the inside of the vertical frame 22 by a locking member 14.

[0035] As shown in Figures 5 and 6, the locking member 14 is attached to the vertical frame 22 on both sides at a location on the inside of the vertical frame 22, which is on the indoor side of the shutter curtain S, and is above the water-stopping plate 11. As shown in Figure 6, the locking member 14 is an L-shaped member (angle material) when viewed from above, and as shown in Figure 5, a screw hole 141 for attaching the mounting screw to the vertical frame 22 is formed as an elongated hole. Because the screw hole 141 is an elongated hole, when the mounting screw 142 is slightly loosened, the locking member 14 can be rotated (rotated around the screw) as well as slid in the longitudinal direction. This improves the work efficiency of installing the water stop plate 11 by attaching and fixing the locking member 14. For example, in Figure 5, by slightly loosening the screw 142 and rotating the locking member 14 counterclockwise around the screw 142, the water stop plate 11 can be tilted inward and removed (installation is the reverse procedure). Also, in Figure 5, by slightly loosening the screw 142 and sliding the locking member 14 upward, the water stop plate 11 can be tilted inward and removed (installation is the reverse procedure). In this way, the work efficiency of installing the water-stopping plate 11 is improved by attaching and fixing the locking member 14. In the case of the latter sliding method, the mounting position of the screw 142 and the elongated hole 141 should be configured such that when the locking member 14 is slid upward, the lower end of the locking member 14 is above the upper end of the water-stopping plate 11. As described above, the locking member 14 holds the water-stopping plate 11, and water is stopped between it and the shutter frame. Therefore, the locking member 14 has the function of "maintaining the contact state of the side sealing member with respect to the vertical frame." Furthermore, in order to improve the fixing force of the water-stopping plate 11 by the locking member 14, the locking member 14 and the water-stopping plate 11 may be configured to make surface contact in the vertical direction for a predetermined length or longer, and may also be fastened to the vertical frame with multiple screws in the elongated hole (or separate screw holes).

[0036] As described above, according to this embodiment, a waterproofing device can be installed for openings where the lower end of the opening is located higher than the ground. The configuration of the window shutter itself can remain the same as conventional ones, and it is possible to implement water-stopping measures for existing window shutter products inexpensively and easily.

[0037] In this embodiment, an angle-shaped locking member 14 is used as an example of a locking member, but the present invention is not limited to this, and the locking member can be any member that can "maintain the contact state of the side sealing member with respect to the vertical frame". Figure 7 shows an example in which the locking member is integrally formed with the vertical frame. In the waterproofing device 1-2' shown in Figure 7, an example is shown in which the locking member 14' is formed as a rib-shaped member extending vertically on the inside of the vertical frame 22', which is on the indoor side of the shutter curtain S. The locking member 14' is formed in the same height range as the water-stopping plate 11, and the water-stopping plate 11 is installed by sliding it in from the top. Furthermore, the locking member 14' is not limited to a rib-shaped member that extends continuously in the vertical direction, but may also be a protruding member or the like that is formed to be scattered in the vertical direction (as long as it can "maintain the contact state of the side sealing member with respect to the vertical frame" as described above).

[0038] <Embodiment 3> Figures 8 and 9 are schematic diagrams showing the waterproofing device of Embodiment 3 according to the present invention attached to a window shutter. Figure 8 is a schematic vertical cross-sectional view showing the area near the bottom of the shutter frame, and Figure 9 is a schematic horizontal cross-sectional view. The waterproofing devices 1-3 of this embodiment are waterproofing devices installed on the window shutter, similar to those in Embodiment 1. Although the shape of the window shutter itself differs from that of Embodiment 1, its concept is the same as that of Embodiment 1. Therefore, the same reference numerals are used for components that have the same concept as those in Embodiment 1, and their explanation here is simplified or omitted. The component indicated by the numeral SF is the window frame of the sash window provided in the opening (the sash attached to the window frame is not shown).

[0039] The waterproofing device 1-3 of this embodiment is the same as in Embodiment 2 in that it is attached to the inside (indoor side) of the shutter frame, but it differs in that a water-stopping sheet is used as the waterproofing device (and the mounting structure for it). Waterproofing devices 1-3 are Waterproof sheet 15 and A water-stopping sheet mounting frame (lower water-stopping sheet mounting frame 161, vertical water-stopping sheet mounting frame 162) is provided on the interior side of the guide rail that guides the opening and closing operation of the shutter curtain (opening / closing mechanism), and holds the water-stopping sheet 15 in a water-stopping manner between itself and the shutter frame (frame body), It is equipped with.

[0040] The basic form of the water-stopping sheet 15 is a substantially rectangular member when viewed from the front (when viewed from the left in Figure 8, and when viewed from above in Figure 9), and is formed of a material that has water-impermeable and flexible properties, such as polyvinyl chloride. As shown in Figure 9, the water-stopping sheet 15 has engaging water-stopping portions 151 at both ends in the width direction. The engaging water-stopping portions 151 are provided extending vertically at both ends of the water-stopping sheet and are inserted into the sheet end insertion frame 1621 of the water-stopping sheet mounting vertical frame 162. The engaging water-stopping portions 151 are formed to be thicker than the slits formed in the sheet end insertion frame 1621 and abut against the slits formed in the sheet end insertion frame 1621, thereby blocking the slits and stopping water flow.

[0041] The vertical frame 162 for mounting the waterproof sheet comprises a sheet end insertion frame 1621 into which the engagement waterproof portion 151 of the aforementioned waterproof sheet 15 is slid vertically and inserted, and a mounting frame mounting portion 1622 positioned between the frame mounting portion 223, which is the mounting portion of the vertical frame 22, which is the shutter frame (frame body), and the wall surface. A sealing member 17 for waterproofing the area is provided between the wall surface and the mounting frame mounting portion 1622. The sheet end insertion frame 1621 has a configuration in which a vertically extending square pipe has a vertically extending slit through which the waterproof sheet 15 is passed, and is installed at a position that is on the interior side of the guide rail of the vertical frame 22 and on the exterior side of the sash window (it is preferable to install it at a position closer to the sash window). The mounting frame mounting portion 1622 is a plate-shaped member that extends in the vertical direction and is attached to the wall surface around the opening (in this embodiment, the outer wall OW) via a sealing member 17 that also extends in the vertical direction, so as to prevent water from entering.

[0042] The lower frame 161 for mounting the water-stopping sheet is a member that extends in the width direction and is attached to the lower frame 23. The lower frame 161 for mounting the water-stopping sheet is made of foamed material, aluminum with foamed material, steel with foamed material, etc., and is waterproofly connected to the vertical frame 162 for mounting the water-stopping sheet at both ends in the width direction, thereby providing water-stopping properties on three sides: both sides and below. The lower frame 161 for mounting the water-stopping sheet is installed on the interior side relative to the water-stopping sheet 15 and provides a water-stopping function by making surface contact with the lower end of the water-stopping sheet 15. Furthermore, the mounting of the water-stopping sheet lower frame 161 to the lower frame 23 can be done using any method that allows for water-stopping attachment of both (for example, fixing with screws or adhesive, or fixing using magnetic force). Alternatively, the water-stopping sheet lower frame may be integrally formed with the lower frame.

[0043] The waterproof sheet 15 can be attached to and detached from the waterproof sheet mounting frame (sheet end insertion frame 1621) by sliding it in the vertical direction. During a flood, when water pressure is applied from the outside, the water-stopping sheet 15 is pressed inward by this pressure, causing the engaging water-stopping portion 151 to be pulled and come into contact with a slit formed in the sheet end insertion frame 1621, thereby closing the slit and stopping the water flow (both ends are stopped from flowing). Furthermore, when water pressure is applied from the outside during a flood, the water-stopping sheet 15 is pressed inward by this pressure, causing the lower end of the water-stopping sheet 15 to be pressed against the lower mounting frame 161 of the water-stopping sheet, thus sealing the lower side as well. Furthermore, by positioning the waterproofing sheet close to the sash window, the waterproofing sheet can be held in place by the sash window when water pressure is applied from the outside.

[0044] As described above, according to this embodiment, a waterproofing device can be installed for openings where the lower end of the opening is located higher than the ground. The configuration of the window shutter itself can remain the same as conventional ones, and it is possible to implement water-stopping measures for existing window shutter products inexpensively and easily.

[0045] In this embodiment, a vertical frame 162 for attaching a waterproof sheet is used as an example, but the present invention is not limited to this, and the vertical frame for attaching a waterproof sheet only needs to be capable of "holding the waterproof sheet in a waterproof manner between itself and the frame." Figure 10 shows an example in which the vertical frame for attaching the waterproof sheet is integrally formed with the vertical frame.

[0046] In the waterproofing device 1-3' shown in Figure 10 (Schematic horizontal cross-sectional view), the portion of the sheet end insertion frame 1621 of the vertical frame 162 for attaching the waterproofing sheet, as described in Embodiment 3, is integrally formed with the vertical frame, thereby constituting the waterproofing sheet attachment frame. The other configurations are the same as those of the waterproofing device 1-3 in Embodiment 3 (the frame attachment portion 223 of the vertical frame 22 is attached to the wall surface around the opening via a sealing member 17 so as to be waterproof).

[0047] The lower frame for attaching the water-stopping sheet is not limited to the lower frame 161 shown in Embodiment 3, but any frame that can "hold the water-stopping sheet in a water-stopping manner between itself and the frame" is acceptable. Figure 11 (a schematic vertical cross-sectional view of the lower part) shows another example of the lower frame for attaching the watertight sheet. In the example shown in Figure 11(a), the waterproofing device 1-3'' is equipped with a water-sealing sheet mounting lower frame 161'' which is roughly U-shaped in cross-sectional view and opens to the upper side, and a groove extending in the width direction is formed by the water-sealing sheet mounting lower frame 161''. In addition, an engaging water-sealing portion 152 is provided at the lower end of the water-sealing sheet 15'', extending in the width direction. The lower side is sealed by inserting the engaging water-stopping portion 152, which is formed with a thickness equal to or greater than the width of the groove (in the left-right direction in Figure 11(a)) of the lower frame 161' for mounting the water-stopping sheet, into the groove. Because the engaging water-stopping portion 152 is formed to be thicker than the water-stopping sheet, it functions as a water pressure receiving surface that can penetrate deeper into the groove when subjected to water pressure during floods, thereby enhancing the water-stopping function. Note that while Figure 11(a) shows an example where the groove opens to the upper side, the direction of the opening can be any direction. Figure 11(b) shows an example where the groove opens to the outside (waterproofing sheet mounting lower frame 161''). Figure 11(c) shows an example where the engaging water-stopping portion is not formed on the lower end of the water-stopping sheet, but is a separate component (a bar member extending in the width direction) from the water-stopping sheet. The lower end of the water-stopping sheet is folded back and inserted into the groove of the water-stopping sheet mounting lower frame 161', and the engaging water-stopping portion 152', which is the bar member, is inserted into the inside of the folded-back portion to stop water from entering the lower end. Although the example here shows the lower end of the water-stopping sheet being folded back, it is sufficient for the lower end of the water-stopping sheet to be stopped by the groove of the water-stopping sheet mounting lower frame 161', and folding back is not mandatory. Regarding the lower frame for attaching each water-stopping sheet shown in Figure 11, it is possible to attach a separate component to the lower frame 23 (any mounting method that can stop water flow may be adopted), or to form it integrally with the lower frame 23, as described in Embodiment 3.

[0048] Alternatively, the watertight seal may be applied to the lower side without providing a lower frame for attaching the watertight sheet. Figure 12 (a schematic vertical cross-sectional view of the lower part) shows an example without a lower frame for attaching the watertight sheet. In the waterproofing device 1-3'''' in the example shown in Figure 12, a folded portion 153 is provided on the lower end side of the water-stopping sheet 15'''', and water is stopped from the lower side by pressing this folded portion against the lower frame 23 with the shutter curtain S. The folded portion 153 is preferably made of a sealing member that has flexibility and elasticity, such as one made of foamed sealing material.

[0049] <Embodiment 4> Figure 13 is a schematic perspective view showing the waterproofing device of Embodiment 4 according to the present invention attached to a window shutter. The waterproofing devices 1-4 of this embodiment are waterproofing devices installed on the window shutter, similar to those in Embodiment 1. Although the shape of the window shutter itself differs from that of Embodiment 1, its concept is the same as that of Embodiment 1. Therefore, the same reference numerals are used for components that have the same concept as those in Embodiment 1, and their explanations here are simplified or omitted.

[0050] The waterproofing device 1-4 is attached to at least three sides of the lower part of the shutter frame (frame body) in a way that prevents water from entering, and includes a water-stopping plate mounting frame 18 that holds the water-stopping plate 11 in a way that prevents water from entering between it and the shutter frame.

[0051] The water-stopping plate 11 of the waterproofing device 1-4 has the same configuration as the water-stopping plate 11 of Embodiment 1. Although not shown in Figure 13, it includes a lower sealing member that seals water between the lower part of the water-stopping plate mounting frame 18 and the water-stopping plate 11, and side sealing members that seal water between both sides of the water-stopping plate mounting frame 18 and the water-stopping plate 11 (similar to the water-stopping plate 11 of Embodiment 1, the sealing members are provided so as to surround the water-stopping plate 11 on three sides, including both sides and the lower part).

[0052] The water-stopping plate mounting frame 18 is equipped with guide grooves for receiving both ends of the water-stopping plate 11 in the width direction and a guide groove for receiving the lower part of the water-stopping plate 11, and is attached to the shutter frame in a way that prevents water from entering, either by being attached via a sealing member or by caulking. The guide grooves for receiving the water-stopping plate 11 are formed to surround the water-stopping plate 11 on three sides: both sides and the bottom. The water-stopping plate 11 is installed by inserting it into the guide grooves from the top.

[0053] As described above, according to this embodiment, a waterproofing device can be installed for openings where the lower end of the opening is located higher than the ground. The configuration of the window shutter itself can remain the same as conventional ones, and waterproofing measures can be implemented relatively inexpensively and easily for existing products.

[0054] In each embodiment, the water-stopping plate is shown as a single plate (or panel), but the present invention is not limited to this, and the water-stopping plate may be composed of multiple plates (or panels).

[0055] Figure 14 shows another example of a water-stopping plate, which is an example in which a water-stopping plate is made up of multiple panel bodies. The water-stopping plate 11' in Figure 14 has a folding structure in which two water-stopping plates are joined by a hinge H, allowing it to be folded and unfolded left and right along the vertical axis. A water-stopping structure (such as a tight-fitting structure by providing a sealing member) is provided appropriately at the joint between the two water-stopping plates. The configuration of both sides of the water-stopping plate 11' is the same as that of the water-stopping plate 11 in the embodiment. Furthermore, the configuration of the lower end side of the water-stopping plate 11' is also based on the same concept as that of the water-stopping plate 11 in the embodiment. In other words, the water-stopping plate 11' is based on the same concept as the water-stopping plate 11 in the embodiment, which is divided into two parts and joined together with a hinge H so that it can be folded. As shown in Figures 14(a) and (b), the water stop plate 11' is installed by placing it between the water stop plate mounting frames 18 in a slightly folded state, and then unfolding it to fit the water stop plate 11' into the guide groove of the water stop plate mounting frame 18. In other words, the water stop plate 11' is configured such that "the width dimension decreases when folded and increases when unfolded, allowing the water stop plate to be installed." Note that "width dimension" refers to the length of the member in the width direction (left-right direction in Figures 14(a) and (b), which are top views). The operations shown in Figures 14(a) and (b) are performed at a position (height) where the lower end of the water stop plate 11' does not interfere with the lower side of the water stop plate mounting frame 18. After the operations shown in Figures 14(a) and (b), the installation of the water stop plate 11' is completed by sliding the water stop plate 11' downwards, as shown in Figure 14(c). Although the installation on the water stop plate mounting frame 18 of Embodiment 4 has been described as an example, installation using the water stop plate 11' can also be performed in Embodiments 1 and 2. According to the water-stopping plate 11' in Figure 14, the same effects and advantages as in the embodiment can be obtained, and an excellent advantage can be obtained in that the water-stopping plate can be made compact by folding when stored. Although the example shown here has only one folding point, the design may be made more compact for storage by having multiple folding points (for example, by making it foldable like an accordion), as shown in Figure 15, which illustrates an example of a water-stopping plate 11''.

[0056] When using the folding method shown in Figures 14 and 13, reinforcing members may be provided to maintain the unfolded state. Figure 16 shows an example of such a thing. In the water-stopping plate 11'''' shown in Figure 16, the reinforcing members are composed of a bar member 112 that functions as a bolt and a staple member 113. As shown in Figure 16(a), when the water-stopping plate 11'''' is folded, the bar member 112 and each staple member 113 are provided on the inner surface of the fold. As shown in Figures 16(b) to (d), after the water-stopping plate 11'''' is unfolded, the bar member 112 is slid through each staple member 113, and the bar member 112 is positioned across both sides of the folding point (Figure 16(d)), thereby engaging the bolt and reinforcing the water-stopping plate 11'''' to maintain its unfolded state. As shown in Figure 16(a), the provision of the bar member 112 and each staple member 113 on the inner surface of the fold makes the water-stopping plate more compact when stored (folded). Furthermore, this configuration can also be applied to objects having multiple folding points, such as the water-stopping plate 11'' in Figure 15. The same configuration as in Figure 16 can be applied to the relationship between adjacent plates, thereby achieving compactness in the stored (folded) state, similar to Figure 16.

[0057] Furthermore, in the case of a folding method as shown in Figure 14, the width of the side sealing members 13 at both ends to the outside is made larger than the distance between the guide grooves on both sides of the water stop plate mounting frame 18, so that the water stop plate 11' is pressed into the water stop plate mounting frame 18. The width of the side sealing members 13 at both ends is formed to be greater than the distance between the guide grooves on both sides, and the water-stopping plate 11' is pressed into place. The elastic force of the sealing member generated when the water-stopping plate 11' is fitted in acts to improve the water-stopping function. It is preferable to use a foamed sealing material for a sealing member that is designed to deform in this manner. Furthermore, the concept of press-fitting the water-stopping plate as described above can also be applied to water-stopping plates 11 that are not of the folding type.

[0058] <Embodiment 5> Figure 17 is a schematic vertical cross-sectional view showing the waterproofing device of Embodiment 5 according to the present invention attached to a window shutter. The waterproofing devices 1-5 of this embodiment are waterproofing devices installed on the window shutter, similar to those in Embodiment 1. Although the shape of the window shutter itself differs from that of Embodiment 1, its concept is the same as that of Embodiment 1. Therefore, the same reference numerals are used for components that have the same concept as those in Embodiment 1, and their explanations here are simplified or omitted.

[0059] The waterproofing device 1-5 of this embodiment comprises a main body 1-51 which is a hollow panel body and functions as a floating member, a mounting member 1-52 which is attached to the lower frame 23 of the shutter frame (or a wall surface such as an exterior wall, or a member provided around an opening such as a foundation or base flashing) and rotatably supports the main body 1-51, and a sealing member 1-53 attached to the main body 1-51.

[0060] The main body 1-51 is supported by the mounting member 1-52 so as to be rotatable with the width direction as the axis of rotation, and as shown in Figure 17, it can move from a downward-hanging state to an upright state where it is positioned opposite the lower part of the shutter frame. The main body 1-51 is a roughly rectangular member when viewed from the front, and in the upright position, it has a configuration that covers the lower side of the shutter frame. In the upright position, it has sealing members 1-53 at the locations facing the shutter frame (both sides and the bottom), which seal the lower side of the shutter frame.

[0061] The waterproofing device 1-5 generates buoyancy in the main body 1-51, which is a hollow floating member, when the water level rises during a flood. This causes the main body 1-51 to rotate and move into an upright position, contacting the bottom of the shutter frame. In other words, "the waterproofing member is configured to be able to move upward due to the buoyancy generated in the floating member by the rising water level. Normally, the waterproofing member is located at the bottom of the opening, but when the water level rises, it moves upward to cover at least the lower side of the opening." In the waterproofing device 1-5, the sealing member 1-53 is made to adhere tightly to the shutter frame by water pressure, so that high water-stopping performance can be obtained as the water level rises.

[0062] As described above, with the waterproofing device 1-5 of this embodiment, the waterproofing member, which is normally located below the shutter frame, automatically rises up in the event of flooding to stop water from entering the lower part of the opening. Therefore, it is possible to take measures to stop water even in the event of sudden flooding (reducing problems such as not being able to take measures to stop water in time).

[0063] In this embodiment, the waterproofing member (water-stopping plate) itself functions as a floating member as an example, but the present invention is not limited to this, and the floating member may be configured separately from the waterproofing member. Also, although the movement of the waterproofing member is given as an example by rotational movement, the present invention is not limited to this, and it is sufficient if "the waterproofing member, which is normally located at the bottom of the opening, is configured to cover at least the lower side of the opening by moving upward when the water level rises." Figure 18 shows a waterproof device 1-5-1 as an example of such a device. The waterproofing device 1-5-1 is a substantially rectangular member in front view, and has a configuration that covers the lower side of the shutter frame when raised (Figure 18(c)). It has sealing members 1-5-11 at the locations facing the shutter frame when raised (both sides and the bottom), a water-stopping member that stops water from entering the lower side of the shutter frame, a hollow floating member 1-5-12 provided below the water-stopping member, and a locking member 1-5-13 (angle material) attached to the vertical frame 22 that holds the water-stopping member so that it can slide in the vertical direction. As can be seen from Figure 18(c), the waterproofing device 1-5-1 generates buoyancy in the floating member 1-5-12 when the water level rises during a flood. This causes the water-stopping member to slide upward, covering the lower part of the shutter frame and providing a water-stopping function.

[0064] In each embodiment, a sliding glass door was described as an example of a window to which a window shutter is installed. However, the present invention is not limited to this, and the concepts described in each embodiment can also be applied to waist-high windows and the like.

[0065] Furthermore, while each embodiment uses an example of a waterproofing device that covers the lower side (part of the window shutter) of the window shutter (opening), the present invention is not limited to this, and if possible, it may cover the entire window shutter (opening) (the water-stopping member may be formed to cover the entire window shutter).

[0066] In each embodiment, a window shutter consisting of a single unit was used as an example, but the application of the waterproofing device according to the present invention is not limited to this, and the waterproofing device according to the present invention can be applied to any device that functions as a window shutter (for example, a device in which the sash and shutter are integrally configured).
