DETAILED DESCRIPTION OF THE INVENTION

[0008] Embodiment 1 The method of attaching the water-stopping member to the opening / closing device of embodiment 1 is a method of attaching the water-stopping member 8 to the opening / closing device 1, which is equipped with left and right guide rails 5, 5 arranged on both left and right widthwise end sides of the opening A formed in an architectural structure and extending in the vertical direction of the opening A, and an opening / closing body 4 whose left and right widthwise end sides are guided by the left and right guide rails 5, 5 and are movable in the vertical direction to open and close the opening A, as shown in Figure 1. That is, the left water-stopping member mounting device 6 is mounted to the lower end of the left guide rail 5, and the right water-stopping member mounting device 6 is mounted to the lower end of the right guide rail 5, and then the left end of the water-stopping member 8 is mounted to the left water-stopping member mounting device 6, and the right end of the water-stopping member 8 is mounted to the right water-stopping member mounting device 6, thereby making it possible to easily mount the water-stopping member 8 to the opening and closing device so as to block the lower side of the opening A. In this specification, the terms up, down, left, right, front, and rear are defined as directions shown in each of FIGS. The front side is "either the indoor side or the outdoor side," and the rear side is "either the indoor side or the outdoor side," but in embodiment 1, an example will be described in which the front side is the outdoor side and the rear side is the indoor side, and the left and right are the left and right when viewing the opening A from the front side (outdoor side) (i.e., the left and right in Figures 2 to 4 are shown based on the left and right shown in Figure 1). Furthermore, "architectural structures" refers to so-called buildings such as detached houses, apartment buildings, buildings, warehouses, factories, etc., exterior structures such as garages, carports, gates, and fences, and structures such as tunnels and underground shopping malls.

[0009] First, the opening and closing device 1 will be described in detail. As shown in Figure 1, the opening and closing device 1 is an opening and closing device also known as a shutter device, and includes a case 2, an opening and closing mechanism 3, an opening and closing body 4 also known as a shutter curtain, which is attached to the winding body of the opening and closing mechanism 3 so that it can be wound up and unwound, and left and right guide rails 5, 5. That is, the switching device 1 may be a well-known existing switching device 1.

[0010] The case 2 is attached to the main body 11 of the architectural structure as a mounting part located above an opening A such as an entrance or window formed in the architectural structure, and is configured to have a storage space for accommodating the opening / closing mechanism 3 and the opening / closing body 4 that is wound up on the winding body of the opening / closing mechanism 3.

[0011] As shown in Figure 1, the opening / closing mechanism 3 includes a winding body such as a winding shaft or a winding frame that winds up the opening / closing body 4, and an opening / closing drive means (not shown) that rotates the winding body around the rotation center line 3a of the winding body as the center of rotation. The winding body is configured to include, for example, a shaft (rotational center axis) 31 formed from a steel pipe with a circular cross section, a plurality of wheels 32 provided on at least both end sides of the shaft 31, and reinforcing members (not shown) that connect the plurality of wheels 32 together. In the case of an electric opening / closing device, the opening / closing drive means is composed of an electric motor (not shown) as a drive source that rotates the winding body in the winding direction and the unwinding direction, and a power transmission mechanism such as a gear transmission mechanism that transmits the rotational force of the electric motor to the winding body; in the case of a manual opening / closing device, it is composed of a spring (not shown) that rotates the winding body in the winding direction, and a power transmission means such as a pulley that transmits the rotational force stored in the spring to the winding body.

[0012] The opening / closing body 4 that opens and closes the opening A is configured to include, for example, a slat portion 41, a one end component member 42, and an other end component member 43. The slat portion 41 is formed by a plurality of slat members 45, 45.... The slat members 45 are formed by elongated members that are long in the direction along the rotation center line 3a of the winding body. The slat portion 41 is formed in the shape of a rectangular plate, with the longitudinal ends of adjacent slat members 45 aligned and the long sides connected to each other by engaging portions not shown in the figure, so that multiple slat members 45, 45... are continuous in a direction perpendicular to the longitudinal direction of the slat members 45 (the direction along the long sides of the slat members 45), and the slat portion 41 is bendable at the connecting portions. The one end component 42 is a member called a water dripper or the like, and is formed of a long member connected to the long side of the slat member 45 located at one end (lower end) of the slat portion 41. The other end component 43 is a component called a hanging point, etc., and is a connecting plate that is intermittently provided along the long side of the slat member 45 located at the other end (upper end) of the slat portion 41, and is connected to the winding body.

[0013] The guide rails 5, 5 are members that guide the left and right widthwise end portions of the opening / closing body 4 that opens and closes the opening A, i.e., the left and right side edges 4a, 4a, in the up and down direction, and are provided at the left and right ends of the opening A so as to extend in the up and down direction of the opening A at a distance from each other in the left and right directions (opening width direction) based on the center of the rectangle of the opening A, and are provided with guide grooves 5a that extend in the up and down direction of the opening A. The left and right side edges 4a, 4a of the opening / closing body 4 are guided in the vertical direction, which is the opening and closing direction of the opening / closing body 4, via the opposing guide grooves 5a, 5a of the guide rails 5, 5, causing the opening / closing body 4 to move in the vertical direction and open and close the opening A. That is, the opening and closing device 1 has left and right guide rails 5, 5 arranged at both left and right widthwise ends of the opening A and extending in the vertical direction of the opening A, and the opening and closing body 4 is arranged so that both left and right widthwise ends are guided by the left and right guide rails 5, 5 and can move in the vertical direction to open and close the opening A.

[0014] 3, the guide rail 5 is formed to have a concave cross section. That is, the guide rail 5 includes, for example, a front plate 52 and a rear plate 51 that face each other in parallel, and a groove bottom plate 53 that connects one end (left end or right end) of the front plate 52 and one end (left end or right end) of the rear plate 51, and the guide groove 5a is formed by a concave groove surrounded by the front plate 52, the rear plate 51, and the groove bottom plate 53.

[0015] On the other end side (right end side or left end side) of the inner surface 52i of the front plate 52 and the other end side (right end side or left end side) of the inner surface 51i of the rear plate 51, for example, front and rear reinforcing protrusions 54, 54 that protrude in directions approaching each other and front and rear anti-detachment protrusions 55, 55 that protrude in directions approaching each other are provided. The anti-slip protrusions 55, 55 are provided to engage with anti-slip members (not shown) provided on the side edges 4a of the opening / closing body 4 to prevent the side ends of the opening / closing body 4 from slipping off the guide rails 5. The reinforcing protrusions 54 are provided at one end of the inner surface 52i of the front plate 52 and at one end of the inner surface 51i of the rear plate 51, and are formed so that the distance a (a is not shown) between these front and rear reinforcing protrusions 54 becomes the groove opening of the guide groove 5a. The retaining projection 55 is provided on the groove bottom plate 53 side at a predetermined distance from the reinforcing projection 54 . In addition, the distance a between the front and rear reinforcing protrusions 54 is the same as or greater than the distance b (b is not shown) between the front and rear anti-pullout protrusions 55.

[0016] The opening and closing device 1 is provided with opening and closing body stoppers 50, 50 on the lower sides of the left and right guide rails 5, 5, respectively. The opening / closing body stopper 50 is provided to protrude from the inner surface 53i of the groove bottom plate 53 of the guide rail 5, and is configured as a protrusion having an engagement surface 50E that engages with an engagement member 46 of the opening / closing body 4 described later, or an engagement surface 50E that engages with an attachment portion 6a of the water-stopping member attachment device 6 described later. The protrusion is formed, for example, in the shape of a hook. The engagement surface 50E is configured, for example, by a horizontal surface that forms the lower surface of the protrusion that constitutes the opening / closing body stopper 50, and is configured so that the engagement portion 46T, which is, for example, the upper portion of the engagement member 46, engages with the engagement surface 50E. In other words, when the opening / closing body 4 closes the opening A, the left engaging member 46 protrudes to the left from the left side edge 4a on the lower side of the opening / closing body 4, and the right engaging member 46 protrudes to the right from the right side edge 4a on the lower side of the opening / closing body 4, and these left and right engaging members 46, 46 engage with the engaging surfaces 50E, 50E of the left and right opening / closing body stoppers 50, 50, thereby maintaining the opening / closing body 4 in a closed state in which the opening A is closed. The slat member 45E located at the lowest end of the plurality of slat members 45, 45 constituting the slat portion 41 of the opening / closing body 4 is called a baseboard or the like. The left and right engaging members 46, 46 described above are provided so as to protrude from the left and right side edges 4a, 4a of the slat member 45E called the baseboard or the like.

[0017] Although not shown, the opening and closing device 1 is equipped with a locking device that includes, for example, a key bar that functions as the above-mentioned engagement member 46 and a key operating lever that moves the key bar back and forth in the left and right directions. The key bar and key operating lever of the locking device are interlocked, for example, by forming a link mechanism. By operating the key operating lever to lock, the left end of the key bar protrudes leftward from the left side edge 4a of the lower part of the opening / closing body 4, and the right end of the key bar protrudes rightward from the right side edge 4a of the lower part of the opening / closing body 4, and the left end of the key bar protrudes rightward from the right side edge 4a of the lower part of the opening / closing body 4 to engage with key receivers that function as opening / closing body stoppers 50, 50 provided on the left and right guide rails 5, 5, the opening / closing body 4 is locked and maintained in a closed state with the opening A closed. Furthermore, by operating the key operating lever to unlock, the engagement between the key bar and the key receiver is released, and the opening / closing body 4 is wound up on the winding body, opening the opening A.

[0018] The opening and closing device 1 shown in Figure 1 is an example of an opening and closing device 1 called a window shutter device, which is attached to the outside of a sash frame 13 that forms the frame of a window section 12 formed in an opening A of an architectural structure, and the opening and closing device 1 has guide rails 5, 5 attached to the main body 11 of the architectural structure via guide rail mounting members 14.

[0019] The water-stopping member 8 is configured, for example, to include a water-stopping plate 81, a lower end watertightness maintaining means 82 provided on the lower end surface 81E of the water-stopping plate 81 to maintain watertightness with the lower surface G of the opening A, and left and right watertightness maintaining means 83, 83 provided on the left and right ends of the rear surface 81R of the water-stopping plate 81 to maintain watertightness with the inner surface 51i of the rear plate 51 of the guide rail 5.

[0020] The water stop plate 81 is formed from a plate having a plate surface corresponding to the size of the opening formed between the lower end (lower end surface of the slat member 45E) of the slat portion 41 of the opening / closing body 4 and the lower surface G of the opening A when the engaging members 46, 46 on the lower side of the opening / closing body 4 are engaged with the opening / closing body positioning stoppers 6c, 6c, as described below. In other words, the waterstop plate 81 may be made of a plate material having a vertical height dimension corresponding to the desired waterstop height H (see Figure 2), a horizontal width dimension corresponding to the distance between the left and right waterstop member mounting devices 6, 6 attached to the lower ends of the left and right guide rails 5, 5, and a front-to-back width dimension formed to the desired thickness dimension capable of resisting water pressure. The material of the waterstop 81 is not critical, but it may be made of a lightweight metal such as an aluminum profile.

[0021] The lower end watertightness maintaining means 82 is attached by adhesive means such as an adhesive seal so that the plate-shaped watertightness maintaining means of a predetermined thickness is provided continuously over the entire lower end surface 81E of the waterstop plate 81. The left and right watertightness maintaining means 83, 83 are attached by adhesive means such as adhesive seals so that, for example, rod-shaped watertightness maintaining means of a predetermined thickness are continuously provided at the left and right ends of the rear surface (plate surface) 81R of the waterstop plate 81, extending between the upper end surface 81T of the waterstop plate 81 and the lower end surface 82E of the lower end watertightness maintaining means 82. The waterstop 81 is installed so that the front surface 81F is positioned on the side that receives the water pressure P, and the rear surface 81R of the waterstop 81 is the plate surface opposite the front surface 81R that receives the water pressure P. In other words, the left and right watertightness maintaining means 83, 83 are attached to the rear surface 81R, which is the plate surface opposite to the front surface 81F, which is the plate surface of the waterstop 81 that receives the water pressure, and are means for maintaining watertightness with the inner surface 51i of the rear plate 51 of the guide rail 5.

[0022] The lower end watertightness maintaining means 82 and the left and right watertightness maintaining means 83, 83 may be made of, for example, a rubber sealing material such as a rubber sponge made of EPDM (ethylene propylene diene rubber), a sealing material with water swelling properties, etc., but sealing materials made of other materials may also be used. As an example of the lower end side watertightness maintaining means 82 and the left and right watertightness maintaining means 83, 83, it is preferable to use a semi-closed, semi-open cell foamed EPDM sealing material or the like, which is made by compounding a foaming agent with rubber and forming the rubber into a porous structure by gas generated by thermal decomposition of the foaming agent.

[0023] Next, the opening / closing body stopper 50 provided on the lower side of the guide rail 5, the water-stopping member mounting device 6, and the water-stopping member 8 will be described in detail. In the following, based on Figures 2 to 4, we will mainly explain the lower end of the right guide rail 5, the right water-stopping member mounting device 6 attached to the lower end of the right guide rail 5, and the right-hand side of the water-stopping member 8 (in other words, when viewing the opening A from the rear (indoor side), we will explain the lower end of the left guide rail 5, the left water-stopping member mounting device 6 attached to the lower end of the left guide rail 5, and the left-hand side of the water-stopping member 8). Therefore, the lower end of the left guide rail 5, the left water-stopping member mounting device 6 attached to the lower end of the left guide rail 5, and the left side portion of the water-stopping member 8 are configured symmetrically to the diagrams shown in Figures 2 to 4, i.e., the "right" in the following description is read as "left" and "left" is read as "right".

[0024] As shown in Figure 4, the right water-stopping member mounting device 6 includes a mounting portion 6a for mounting the right water-stopping member mounting device 6 to the lower end of the right guide rail 5, a water-stopping member mounting portion 6b for mounting the water-stopping member 8, and an opening / closing body positioning stopper 6c.

[0025] The water-stopping member mounting device 6 is configured, for example, as a plate-like body whose vertical length is longer than the vertical length dimension of the water-stopping member 8 and whose plate thickness dimension, which is the front-to-rear width, is smaller than the dimension of the distance b between the opposing front and rear anti-removal protrusions 55, and is provided with a mounting portion 6a, a water-stopping member mounting portion 6b, and an opening / closing body positioning stopper 6c.

[0026] The mounting portion 6a of the right water-stopping member mounting device 6 is a mounting portion for the opening and closing device 1, and is formed in a shape that can be mounted to the opening and closing body stopper 50 provided on the lower side of the right guide rail 5. The attachment portion 6a is configured by a U-shaped recess 61 formed on the right end surface 6R facing the inner surface 53i of the groove bottom plate 53 of the guide rail 5, for example, as shown in FIG. Then, by installing the lower end surface 6E of the right water-stopping member mounting device 6, for example, on the lower end surface of the right guide rail 5, inserting the opening / closing body stopper 50 into the recess 61, and engaging the lower surface 61E of the recess 61 with the engagement surface 50E of the opening / closing body stopper 50, the water-stopping member mounting device 6 is mounted in a state in which its upward movement is restricted by the opening / closing body stopper 50.

[0027] The water-stopping member mounting portion 6b of the right water-stopping member mounting device 6 is formed so as to extend continuously in the vertical direction at the left end of the water-stopping member mounting device 6, as shown in Figure 4, and is composed of an engaging portion 62 that engages with an engaging groove 84 formed so as to extend continuously in the vertical direction at the right end face 81S of the water-stopping plate 81. That is, the fitting portion 62 is provided at the left end of the right water-stopping member mounting device 6 so as to extend continuously in the vertical direction, and is composed of a plate portion having a thickness that fits into the fitting groove 84 .

[0028] Therefore, the waterstop member 8 is attached to the waterstop member mounting portions 6b, 6b of the left and right waterstop member mounting devices 6, 6 so that the fitting grooves 84, 84 formed on the left and right end faces 81S, 81S of the waterstop plate 81 fit into the fitting portions 62, 62 which are the waterstop member mounting portions 6b, 6b of the left and right waterstop member mounting devices 6, 6 attached to the left and right guide rails 5, 5, and the watertightness between the lower end face 81E of the waterstop plate 81 and the lower surface G of the opening A is maintained by the lower end watertightness maintaining means 82, and the watertightness between the left and right end sides of the rear surface 81R of the waterstop plate 81 and the inner surfaces 51i, 51i of the rear plates 51, 51 of the left and right guide rails 5, 5 is maintained by the left and right watertightness maintaining means 83, 83, so that the waterstop member 8 is installed to block the lower side of the opening A. The water blocking member 8 installed in this manner can prevent water from entering from the front side (outdoor side) of the opening A to the rear side (indoor side) of the opening A. That is, the left and right watertightness maintaining means 83, 83 are provided so as to be continuous at the left and right ends of the rear surface (plate surface) 81R of the waterstop 81, spanning between the upper end surface 81T of the waterstop 81 and the lower end surface 82E of the lower end watertightness maintaining means 82, so that the inner surface 51i of the rear plate 51 of the guide rail 5 and the rear surface of the watertightness maintaining means 83 are in close contact, and the waterstop member 8 is installed so that the lower end surface 83E of the watertightness maintaining means 83 is in close contact with the lower end surface of the guide rail 5, thereby preventing water from entering to the left of the left watertightness maintaining means 83 and to the right of the right watertightness maintaining means 83. In other words, water can be prevented from entering into the small gap between the fitting groove 84 of the waterstop 81 and the fitting portion 62 of the waterstop member mounting device 6, and water can be prevented from entering from the front side (outdoor side) to the rear side (indoor side). In addition, by installing the water-stopping member 8 so that the lower end surface 82E of the lower end watertightness maintaining means 82 is in close contact with the lower surface G of the opening A and the lower end surface of the guide rail 5, water is prevented from entering from the front side (outdoor side) to the rear side (indoor side).

[0029] The right water-stopping member mounting device 6 also has an opening / closing body positioning stopper 6c on the upper side. The opening / closing body positioning stopper 6c is configured to have an engaging surface 63E that engages with the right engaging member 46 on the lower side of the opening / closing body 4. 4, the engagement surface 63E is configured by a horizontal plane that forms the lower surface of the engagement body 63 that constitutes the opening / closing body positioning stopper 6c, and is configured so that the engagement surface 63E is engaged with the engagement portion 46T, which is, for example, the upper part of the engagement member 46. The engagement body 63 is formed, for example, in a hook shape. Therefore, by engaging the left and right engaging members 46, 46 on the lower side of the opening / closing body 4 with the engaging surfaces 63E, 63E of the left and right opening / closing body positioning stoppers 6c, 6c, the opening / closing body 4 is maintained in a closed state with the upper opening of the water-stopping member 8 installed to block the lower side of the opening A. In other words, the opening / closing body positioning stopper 6c engages with the engaging member 46 of the opening / closing body 4 and functions as a means for maintaining the position of the lower end of the opening / closing body 4 so that a predetermined state is achieved in which the lower end of the slat portion 41 of the opening / closing body 4 and the lower surface G of the opening A are spaced apart by a distance corresponding to a predetermined water-stopping height H. When the left and right engagement members 46, 46 on the lower side of the opening-closing body 4 are engaged with the engagement surfaces 63E, 63E of the left and right opening-closing body positioning stoppers 6c, 6c, the lower end side of the opening-closing body 4 comes into contact with the upper end surface 81T of the waterstopping member 8 installed so as to close the lower side of the opening A, and the waterstopping member 8 is pressed toward the lower surface G of the opening A by the opening-closing body 4. With this configuration, the lower-end watertightness maintaining means 82 of the waterstopping member 8 is crushed, and the lower end surface 82E of the lower-end watertightness maintaining means 82 of the waterstopping member 8 is maintained in close contact with the lower surface G of the opening A and the lower end surface of the guide rail 5, thereby further improving the watertightness between the waterstopping member 8 and the lower surface G of the opening A and the lower end surface of the guide rail 5. In other words, the opening / closing body positioning stoppers 6c, 6c of the water-stopping member mounting device 6, 6 maintain the opening / closing body 4 so that the water-stopping member 8 attached to the water-stopping member mounting portions 6b, 6b is pressed against the underside of the opening A while engaged with the left and right engaging members 46, 46 protruding from the side edges on the lower side of the opening / closing body 4.

[0030] Next, a method for attaching the water blocking member 8 to the opening and closing device 1 according to the first embodiment will be described in detail. First, in a state in which the opening A is closed by the opening / closing body 4, the locking device is released, the opening / closing body 4 is raised, and the opening A is opened by winding the opening / closing body 4 up. Next, the water-stopping member mounting devices 6 are attached to the lower ends of the left and right guide rails 5, 5. That is, the water-stopping member mounting device 6 is inserted into the guide rail 5 from the side of the opening of the guide groove 5a on the lower end side of the guide rail 5, the lower end surface 6E of the water-stopping member mounting device 6 is placed on the lower end surface of the guide rail 5, and the lower surface 61E of the engaging recess 61 serving as the mounting portion 6a of the water-stopping member mounting device 6 is engaged with the engaging surface 50E of the opening-closing body stopper 50, thereby attaching the water-stopping member mounting device 6 to the lower end of the guide rail 5. The left and right water-stopping member mounting devices 6, 6 are attached symmetrically so that the water-stopping member mounting portions 6b, 6b face each other. Next, the left and right ends of the water-stopping member 8 are inserted into the left and right guide rails 5, 5 from the sides of the openings of the guide grooves 5a on the upper sides of the left and right guide rails 5, 5, and then the water-stopping member 8 is moved downward.The water-stopping member 8 is attached to the left and right water-stopping member attaching devices 6, 6 by fitting the fitting grooves 84, 84 formed on the left and right end faces 81S, 81S of the water-stopping member 8 into the fitting portions 62, 62 serving as the water-stopping member attaching portions 6b, 6b of the left and right water-stopping member attaching devices 6, 6. Finally, the opening / closing body 4 is lowered so that the left and right engagement members 46, 46 on the lower side of the opening / closing body 4 are engaged with the left and right opening / closing body positioning stoppers 6c, 6c. With the above, the installation of the water blocking member 8 to the opening and closing device 1 is completed. The water-stopping member 8 installed in this manner is maintained in a downwardly pressed state by the opening / closing body 4 in which the left and right engaging members 46, 46 on the lower side are engaged with the engaging surfaces 63E, 63E of the left and right opening / closing body positioning stoppers 6c, 6c, thereby maintaining the watertightness maintaining means 82 on the lower end side of the water-stopping member 8 in a crushed state, thereby maintaining good watertightness performance between the water-stopping member 8 and the lower surface G of the opening A and the lower end surface of the guide rail 5, and making it possible to prevent water from entering from the front side (outdoor side) to the rear side (indoor side). Furthermore, the left and right watertightness maintaining means 83, 83 are arranged between the left and right ends of the rear surface 81R of the waterstop 81 and the inner surface 51i of the rear plate 51 of the left and right guide rails 5, 5, and when the front surface 81F of the waterstop 81 is subjected to water pressure P from the front side (outdoor side), the watertightness maintaining means 83 is maintained in a crushed state between the rear surface 81R of the waterstop 81 and the inner surface 51i of the rear plate 51 of the guide rail 5, so that the watertightness performance between the rear surface 81R of the waterstop 81 and the inner surface 51i of the rear plate 51 of the guide rail 5 is maintained well, making it possible to prevent water from entering from the front side (outdoor side) to the rear side (indoor side). The lower end surfaces of the guide rails 5 and the lower surface G of the opening A are formed by the upper surface of a lower frame member provided so as to connect the lower ends of the left and right guide rails 5, 5, for example.

[0031] According to the first embodiment, it is possible to provide a method of attaching the waterstop member 8 to the opening and closing device 1, which allows the waterstop member 8 to be easily and inexpensively provided to an existing opening and closing device 1 and prevents an increase in the cost of the opening and closing device 1. It is also possible to provide a waterstop member attaching device 6 and a waterstop member 8 that can easily implement this method.

[0032] Furthermore, in the opening and closing device with a water-stopping member disclosed in Patent Document 1, it is difficult to remove the water-stopping member and use the opening and closing device. However, according to embodiment 1, the water-stopping member 8 and the water-stopping member mounting devices 6, 6 can be easily removed in the reverse order of the installation order described above. Therefore, when the water-stopping function provided by the water-stopping member 8 is not required, the opening and closing device 1 can be returned to its existing state and used as the existing opening and closing device 1.

[0033] Embodiment 2 The water-stopping member mounting portion 6b of the water-stopping member mounting device 6 may be configured to be formed by a fitting groove that is formed to extend in the vertical direction and into which the left or right edge of the water-stopping member 8 is fitted. In this case, the left and right edge sides of the water-stopping member 8 are formed to extend in the vertical direction and are configured with fitting portions that fit into the fitting grooves. In this case, the rear surfaces 81R of the water-stopping member 8 on the left and right fitting portion sides are configured to fit into the left and right guide rails 5, 5, and left and right watertightness maintaining means 83, 83 that come into watertight contact with the inner surfaces 51i, 51i of the rear plates 51, 51 of the left and right guide rails 5, 5 may be provided on the rear surfaces 81R of the water-stopping member 8 on the left and right fitting portion sides.

[0034] Embodiment 3 The above example shows a water-stopping member 8 configured by providing watertightness maintaining means 82, 83 on a waterstop plate 81, but the waterstop member 8 may also be configured to include a waterstop plate 81, a lower-end watertightness maintaining means provided on the underside G of the opening A and the lower end surface of the guide rail 5 to maintain watertightness between the underside G of the opening A and the lower end surface of the guide rail 5 and the lower end surface 81E of the waterstop plate 81, and left and right watertightness maintaining means provided on the inner surfaces 51i, 51i at the lower side of the rear plates 51, 51 of the left and right guide rails 5, 5 to maintain watertightness between the inner surfaces 51i, 51i and the rear surface 81R on the left and right end surfaces of the waterstop plate 81.

[0035] In the above example, the left and right engaging members 46, 46 on the lower side of the opening-closing body 4 are engaged with the engaging surfaces 63E, 63E of the left and right opening-closing body positioning stoppers 6c, thereby bringing the lower end of the opening-closing body 4 into contact with the upper end surface 81T of the waterstop member 8 and pressing the waterstop member 8 toward the lower surface G of the opening A. However, for example, the waterstop plate 81 may be configured so that the weight of the waterstop plate 81 crushes the lower end watertightness maintaining means 82 of the waterstop member 8, maintaining the lower end surface 82E of the lower end watertightness maintaining means 82 of the waterstop member 8 in close contact with the lower surface G of the opening A and the lower end surface of the guide rail 5. In this case, the lower end of the opening-closing body 4 may be configured not to come into contact with the upper end surface 81T of the waterstop member 8 when the left and right engaging members 46, 46 on the lower side of the opening-closing body 4 are engaged with the engaging surfaces 63E, 63E of the left and right opening-closing body positioning stoppers 6c. In this case, the opening / closing body positioning stoppers 6c, 6c engage with engaging members 46, 46 protruding from the side edge on the lower side of the opening / closing body 4, and function as a structure to maintain the opening / closing body 4 in a closed state in which the opening above the water-stopping member 8 attached to the lower side of the opening A is closed. Furthermore, it is desirable to provide the opening / closing body positioning stopper 6c having this configuration from the viewpoint of crime prevention measures and measures against wind and rain, but it is not necessarily required given the intended purpose of attaching the water-stopping member 8 to the opening / closing device 1.

[0036] In addition, the left and right watertightness maintaining means 83, 83 may be arranged so as to extend continuously between the upper end surface 81T of the waterstop plate 81 and the lower end surface 82E of the lower end watertightness maintaining means 82 at the left and right end sides of the rear surface 81R of the waterstop plate 81, so as to be positioned at the position shown by the imaginary line (dotted line) in Figure 3, i.e., between the anti-detachment protrusion 55 and the reinforcing protrusion 54. Furthermore, the left and right watertightness maintaining means 83, 83 may be provided at both the positions indicated by the solid lines and the positions indicated by the imaginary lines in FIG. Furthermore, the guide rail 5 may not have the retaining projection 55 or the reinforcing projection 54. In other words, the left and right watertightness maintaining means 83, 83 provided on the waterstop 81 should be provided in a position where they are maintained in a crushed state between the rear surface 81R of the waterstop 81 and the inner surface 51i of the rear plate 51 of the guide rail 5 when the waterstop 81 is subjected to water pressure P from the front side (outdoor side).

[0037] The mounting portion 6a of the water-stopping member mounting device 6 may be configured to be mounted to the guide rail 5 with mounting screws or the like.

[0038] Furthermore, the water-stopping member mounting portion 6b of the water-stopping member mounting device 6 may be configured to mount the water-stopping member using mounting screws or the like.

[0039] Furthermore, the method of attaching a water-stopping member to an opening / closing device and the water-stopping member attaching device of the present invention can be applied to shutter devices other than window shutter devices, and other opening / closing devices that are equipped with guide rails that guide the opening / closing body.
