Mode for Carrying Out the Invention

[0017] Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. Note that the following embodiments are one form when embodying the present invention and do not limit the present invention within its scope.

[0018] Figures 1 and 2 are schematic diagrams showing the waterproofing device of Embodiment 1 according to the present invention attached to a sash window, with Figure 1 being a schematic vertical cross-sectional view and Figure 2 being a schematic horizontal cross-sectional view. The waterproofing device 1 of this embodiment is a waterproofing device installed on a sash window, and a sash window is an "opening in which the lower end of the opening is located higher than the ground." The waterproofing device 1 of this embodiment includes a waterproofing member mounting frame 12 that is attached to the inside of the interior frame F of a sash frame, which is a frame for installing a panel body (outer sash SD1, inner sash SD2) such as a glass window in an opening, and a water-stopping plate 11 that is attached to the waterproofing member mounting frame 12 in a water-stopping manner. In the following explanation, "width direction" refers to the direction along the window's opening and closing direction (the sliding direction of the sash), and "width dimension" refers to the length of the member along the width direction.

[0019] A sash window is a sliding window in which an outer sash SD1 and an inner sash SD2, such as a glass window, are installed in a sash frame consisting of an upper frame 21, a lower frame 22, and a pair of left and right vertical frames 23, which is installed in an opening formed in the wall of the house (the wall surface W to which the exterior wall OW is attached). In addition, the sash window in this embodiment is a sliding window in which the lower frame 22 is installed on the foundation B of the house, and the lower frame (lower frame material) of the inner frame (decorative window frame) F of the window is at the same level as the floor surface (or the lower frame F is the floor surface itself, such as flooring material). The lower frame 22 is formed with rail members 222, rail member 223, and rail member 221, which guide the movement of the outer sash SD1, the inner sash SD2, and the screen door (not shown in particular), each having a roller at its lower end. Since the concept of the waterproofing device of this embodiment can be applied to any sash window, further detailed explanation regarding the sash window itself will be omitted.

[0020] The water-stopping plate 11 is attached to the waterproofing member mounting frame 12 described below, and by stopping water from entering at least the lower side of the sash window (opening) on ​​the indoor side, it prevents water from entering the sash window portion when the water level rises during a flood. The basic form of the water-stopping plate 11 is a roughly rectangular member when viewed from the front (when viewed from the left side in Figure 1, and from above in Figure 2), and in order to have strength to withstand water pressure and to reduce weight, it has a hollow panel body (or a hollow body filled with a filler such as foamed urethane) made of a metal such as aluminum, steel, steel material, or stainless steel, or a resin material such as PVC (a plate or a plate made by connecting extruded material), acrylic plate, or polycarbonate plate. As shown in Figures 1 and 2, sealing members 111 are provided on the bottom surface and both sides of the water-stopping plate 11. That is, the sealing members 111 are provided so as to surround three sides of the water-stopping plate. 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. Furthermore, as shown in Figure 2, side walls 112 are formed at both ends in the width direction of the water-stopping plate 11, on the outdoor side of the water-stopping plate, and extending from the top to the bottom of the water-stopping plate 11. The side walls 112 and the sealing member 111 constitute the mounting portion for the waterproof member mounting frame 12.

[0021] The waterproofing member mounting frame 12 is a mounting frame for attaching the water-stopping plate 11, and it protrudes inward from the frame F, and has a configuration as a convex portion that extends vertically along the vertical frame members on the lower side of the vertical frame members, which are the vertical members of the frame F. As shown in Figure 2, the waterproofing member mounting frame 12 is a hollow member with a roughly rectangular cross-section. Similar to the water-stopping plate 11, it is a hollow member (or one with a filler such as foamed urethane filled inside the hollow part) made of a metal such as aluminum, steel, stainless steel, or PVC (a sheet or a sheet made by connecting extruded material), acrylic sheet, or polycarbonate sheet, in order to hold the water-stopping plate 11 and provide strength to withstand water pressure, as well as to reduce weight. The waterproofing member mounting frame 12 is attached to the vertical members of the picture frame via a sealing member 121. The waterproofing member mounting frame only needs to be attached to the picture frame in a way that provides a watertight seal; for example, a caulking treatment may be used instead of a sealing member. Furthermore, the waterproofing member mounting frame 12 may be fixedly attached to the vertical members of the picture frame by adhesive or the like, or it may be attached in a way that allows for easy attachment and detachment by screws or the like.

[0022] The width dimension of the sealing members 111 on both sides of the water-stopping plate 11 (the distance between the outer surfaces of the sealing members 111 at both ends in the width direction) is formed to be larger than the distance between the waterproof member mounting frames 12 (protrusions) provided on the vertical members of the frame on both sides. With this configuration, when the water-stopping plate 11 is attached to the waterproof member mounting frame 12, the water-stopping plate 11 (sealing members 111) is pressed into place between the waterproof member mounting frames 12. The elastic force of the sealing members 111 generated when the water-stopping plate 11 is fitted into the waterproof member mounting frame 12 acts as a locking force to maintain the attached state of the water-stopping plate 11 and also acts to improve the water-stopping function. It is preferable to use a foamed sealant for a sealing member that is designed to deform in this way. Further improvement in the water-stopping function can be expected. The water-stopping function of the lower part of the water-stopping plate 11 is achieved by the sealing member 111 on the lower part of the water-stopping plate 11 being in close contact with the lower frame material, which is the lower material of the picture frame F, as shown in Figure 1. When installing the water-stopping plate 11, it is preferable to push the water-stopping plate 11 downward to increase the contact with the lower frame material. In order to maintain this downward-pushed state of the water-stopping plate 11 (the state in which the sealing member 111 on the lower part of the water-stopping plate 11 is in close contact with the lower frame material), a fixing member (such as a fixing bracket) may be provided to fix the mounting position of the water-stopping plate 11 in the height direction, or the water-stopping plate may be configured to be screwed to the waterproof member mounting frame. The water-stopping plate 11 provides a sealing member at a location facing the waterproofing member mounting frame or frame, thereby performing a water-stopping function on the interior side of the sash window.

[0023] As described above, the waterproofing device 1 of this embodiment allows for relatively inexpensive and easy waterproofing of existing sash windows. With the increasing severity of damage caused by floods in recent years, the amount of damage from flooding above floor level has also increased, and there is a growing need to prevent or reduce the damage from such flooding. To prevent or reduce the damage from flooding above floor level, it is essential to stop water from entering through sliding windows, but due to their structure, it is not easy to stop water from entering through sliding doors such as double-hung windows. In contrast, the waterproofing device 1 of this embodiment is extremely useful because it allows for inexpensive and easy water-stopping measures to be taken for existing sash windows.

[0024] Furthermore, the water-stopping plate 11 and the waterproofing member mounting frame 12 are mutually detachable and can be attached to the frame to stop water from entering at least the lower side of the sash window. Various specific structures are possible. Figures 3-9 show examples of other embodiments relating to water-stopping plates and mounting frames for waterproofing components.

[0025] Figure 3 is a schematic vertical cross-sectional view showing another example of a waterproofing device. In the example shown in Figure 3, the waterproofing device 1' has the same configuration on both sides as the waterproofing device 1 of the embodiment, but with the same configuration on the lower side as well. The configuration other than the lower side is the same as that of the waterproofing device 1 of the embodiment. As shown in Figure 3, a side wall 112' is formed on the lower side of the water-stopping plate 11' of the waterproofing device 1', extending to both ends in the width direction of the water-stopping plate on the outdoor side of the water-stopping plate. The side wall 112' is formed continuously with the side walls 112 on both sides, and therefore is provided continuously on three sides of the water-stopping plate. The mounting portion to the waterproofing member mounting frame 12 is formed by the side wall 112' and the sealing member 111, as in the embodiment. Furthermore, as shown in Figure 3, a waterproofing member mounting frame 12' is provided on the lower frame material. The basic concept of the waterproofing member mounting frame 12' is the same as that of the waterproofing member mounting frame 12 in Embodiment 1, and it is attached to the lower frame material via a sealing member 121. The waterproofing member mounting frame 12' extends in the width direction and is connected to the waterproofing member mounting frames 12 on both sides, and therefore, protrusions (protrusions that project inward along the frame) are continuously formed on three sides of the lower inner side of the frame F. This configuration improves the watertightness of the lower side of the watertight plate. In the embodiment, the side wall 112 and the side wall 112' in the example of Figure 3 are shown as being continuously provided extending in the vertical or width direction, but they may also be provided intermittently or formed as one or more protrusions (engaging parts) (as long as they can engage with the waterproof member mounting frame 12 or the waterproof member mounting frame 12').

[0026] Figure 4 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 1-1 in Figure 4 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 mounting configurations on both sides and the bottom of the water-stopping plate 1-1 are the same as those of the water-stopping plate 11' in Figure 3. In other words, the water-stopping plate 1-1 is conceptually similar to the water-stopping plate 11' in Figure 3, but divided into two sections and joined together with a hinge H so that they can be folded. As shown in Figures 4(a) and (b), the water-stopping plate 1-1 is installed by placing it between the waterproofing member mounting frames 12 in a slightly folded state, and then unfolding it to fit it between the waterproofing member mounting frames 12. In other words, the water-stopping plate 1-1 is configured such that "its width dimension decreases when folded and increases when unfolded, allowing it to be installed on the waterproofing member mounting frames." The installation of the water stop plate 1-1 is completed by performing the work shown in Figures 4(a) and (b) at the installation position (height) shown in Figure 2(c), or by performing the work shown in Figures 4(a) and (b) at a position (height) where the lower end of the water stop plate 1-1 does not interfere with the lower side of the waterproofing member mounting frame 12, and then sliding the water stop plate 1-1 downward as shown in Figure 2(c). According to the water-stopping plate 1-1 in Figure 4, the same effects and advantages as in the embodiment can be obtained, and the excellent effect of being able to make the water-stopping plate compact by folding it when stored can be obtained. Although this example uses a design with only one folding point, as shown in Figure 5, which illustrates an example of a water-stopping plate 1-1', the design may be made more compact for storage by incorporating multiple folding points (for example, by allowing it to fold in an accordion-like fashion).

[0027] When using the folding method shown in Figures 4 and 5, reinforcing members may be provided to maintain the unfolded state. Figure 6 shows an example of such a thing. In the waterproof device 1-2 shown in Figure 6, the reinforcing members are composed of a bar member 15 that functions as a bolt and a staple member 16. As shown in Figure 6(a), when the waterproof device 1-2 is folded, the bar member 15 and each staple member 16 are provided on the inner surface of the fold. As shown in Figures 6(b) to (d), after the waterproof device 1-2 is unfolded, the bar member 15 is slid through each staple member 16, and the bar member 15 is positioned across both sides of the folding point (Figure 6(d)), thereby engaging the bolt and reinforcing the waterproof device 1-2 to maintain its unfolded state. As shown in Figure 6(a), the provision of the bar member 15 and each staple member 16 on the inner surface of the fold allows for compact storage (folded state). This configuration can also be applied to objects with multiple folding points, such as the water-stopping plate 1-1' in Figure 5. Even when there are multiple folding points, the same configuration as in Figure 6 can be applied to the relationship between adjacent panels, thereby achieving compactness in the storage state (folded state), similar to Figure 6.

[0028] Figure 7 is a schematic horizontal cross-sectional view showing yet another example of a waterproofing device. Note that while Figure 7 shows the vicinity of one end of waterproofing device 1-3, the vicinity of the other end is similar (symmetrical). The basic configuration of the water-stopping plate of the waterproofing device 1-3 in the example shown in Figure 7 is the same as in Embodiment 1, but the sealing members 111-3 provided at both ends in the width direction are also provided on the indoor side of the side wall (mounting portion) 112 in a manner that extends from the sealing member 111 of Embodiment 1. As a result, the sealing member is positioned between the side wall 112 and the waterproofing member mounting frame 12-3, that is, "the water-stopping plate has a mounting portion that contacts the protrusion from the outdoor side via the sealing member." Furthermore, the waterproofing member mounting frame 12-3 has a side that contacts the frame F that extends outwards, and an outward-facing side wall is formed at its tip, giving it a shape resembling the number 6 in cross-sectional view (top view). At the extension of the contact surface with the frame F, a screw mounting portion for screw fastening to the frame F is formed, and a guide groove 123 is formed by the outdoor side wall. The guide groove 123 is a guide groove that receives the water-stopping plate 11 (side wall (mounting portion) 112) inserted from above. By being a groove that receives the side wall 112, it holds the water-stopping plate 11 in place (preventing it from falling outwards, etc.). As can be seen from the example in Figure 7, when water pressure is applied from the outside during a flood, this water pressure generates a force that presses the water-stopping plate against the waterproofing member mounting frame (i.e., a force that causes the sealing member 111-3 to adhere tightly to the waterproofing member mounting frame), thereby further improving waterproofing performance. In the example in Figure 7, in addition to the sealing member provided on the interior side of the side wall 112, there is also a sealing member on the side of the water-stopping plate, similar to Embodiment 1 (the sealing member is L-shaped when viewed from above). However, it is also possible to have only the sealing member provided on the interior side of the side wall 112. The water-stopping structure on the lower side of the waterproofing device 1-3 may be the same as that of Embodiment 1, the same as that of Figure 3, or a structure in which the same water-stopping structure as that of both ends of the waterproofing device 1-3 described above is continuously provided on the lower side as well (having the configuration described above on three sides).

[0029] Figure 8 is a schematic horizontal cross-sectional view showing yet another example of a waterproofing device. Note that while Figure 8 shows the vicinity of one end of waterproofing device 1-4, the vicinity of the other end has a similar (symmetrical) configuration. In the example shown in Figure 8, the water-stopping plate 11-4 of the waterproofing device 1-4 is provided with interior-facing side walls 113 at both ends, thereby forming guide grooves 114 at both ends in the width direction of the water-stopping plate. The other configurations of the water-stopping plate 11-4 are the same as those of the waterproofing device 1-3 (including the sealing member 111-3) in Figure 7. On the other hand, the waterproofing member mounting frame 12-4 does not have an inner side surface (a surface facing the mounting surface to the frame F) of the waterproofing member mounting frame 12 of Embodiment 1, and therefore has a U-shape when viewed from above. The mounting surface to the frame F is a screw mounting portion for screw fastening, and the U-shape when viewed from above makes it easy to access the screws when installing (or removing) the waterproofing member mounting frame 12-4. Similar to waterproof device 1-3 in Figure 7, the waterproofing device 1-4 is installed by inserting the water-stopping plate into the waterproofing member mounting frame from above, and the guide grooves 114 at both ends in the width direction of the water-stopping plate are guide grooves that receive the waterproofing member mounting frame 112-4. As shown in the example in Figure 8, the same effects and advantages as those of the waterproofing device 1-3 in Figure 7 can be obtained. Note that, as with the waterproofing device 1-3, the sealing member 111-3 may consist only of the sealing member provided on the interior side of the side wall 112. The water-stopping structure on the lower side of the waterproofing device 1-4 may be the same as that of Embodiment 1, the same as that of Figure 3, the same as that of Figure 7, or it may be one in which the same water-stopping structure as that of both ends of the waterproofing device 1-4 described above is continuously provided on the lower side as well (having the configuration described above on three sides).

[0030] Figure 9 is a schematic horizontal cross-sectional view showing yet another example of a waterproofing device. Note that while Figure 9 shows the vicinity of one end of waterproofing device 1-5, the vicinity of the other end has a similar (symmetrical) configuration. In the example shown in Figure 9, the water-stopping plate 11-5 of the waterproofing device 1-5 does not have side walls at both ends in the width direction as described in the above examples. Instead, the end of the water-stopping plate (panel body) itself functions as a "mounting portion," and a sealing member 111-5 is provided at the end of the water-stopping plate itself. The sealing member 111-5 is formed to extend from the side of the water-stopping plate 11-5 toward the interior side and is provided from the top to the bottom of the water-stopping plate 11-5. The portion of the sealing member 111-5 formed on the interior side surface of the water-stopping plate contacts the waterproofing member mounting frame (protrusion) 12-5 from the exterior side. In other words, "the water-stopping plate has a mounting portion that contacts the protrusion from the exterior side via the sealing member." The waterproofing member mounting frame 12-5 is structurally the same as the waterproofing member mounting frame 12-4 in Figure 8, but its U-shaped structure provides a guide groove 123-5 for receiving the water-stopping plate inserted from above. As shown in the example in Figure 9, the same effects and advantages as those of the waterproofing devices in Figures 7 and 8 can be obtained. Note that, as in the examples in Figures 7 and 8, the sealing member 111-5 may consist only of the sealing member provided on the indoor side of the water-stopping plate. The water-stopping structure on the lower side of the waterproofing device 1-5 may be the same as that of Embodiment 1, the same as that of Figures 3, 7, and 8, or it may be a structure in which the same water-stopping structure as that of both ends of the waterproofing device 1-5 described above is continuously provided on the lower side as well (having the configuration described above on three sides).

[0031] In the above explanations, the example given is that the sealing member between the waterproofing member mounting frame and the water-stopping plate is provided on the water-stopping plate side. However, the sealing member between the waterproofing member mounting frame and the water-stopping plate may also be provided on the waterproofing member mounting frame side.

[0032] Although the above descriptions have focused on sliding sash windows, the present invention is not limited to these. For example, the concepts described above can be applied to any sliding window, including single-hung sash windows. Furthermore, although the invention was explained using a sliding glass door as an example, the present invention is not limited to this, and the concepts described above can also be applied to waist-high windows and the like.

[0033] Furthermore, while the above descriptions use examples of waterproofing devices that cover the lower part (part of the sash window) of a sash window (opening), the present invention is not limited to this, and may also be designed to cover the entire sash window (opening) (the water-stopping member may be formed to cover the entire sash window).
