Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the water stop device disclosed in Patent Document 1, the presence of a door for attaching the water stop plate is indispensable, and it is impossible to block an opening without a door to prevent water from passing through. In addition, in the water stop device disclosed in Patent Document 2, when the width of the water stop member is slightly larger than the opening width of the door frame and the water stop member is installed in the door frame, the water stop member is installed in the door frame in a press-fitting state while being slightly compressed in the width direction. Also, when the width of the water stop member is equal to or smaller than the opening width of the door frame and the water stop member is installed, the first part of the water stop member is installed by being sandwiched between the door and the door stop of the door frame. However, in the water stop device disclosed in Patent Document 2, when the water stop member is installed in the door frame in a press-fitting state while being slightly compressed in the width direction, the door frame and the water stop member may be damaged. Also, when the first part of the water stop member is installed by being sandwiched between the door and the door stop of the door frame, the presence of a door for supporting the water stop plate is indispensable, and it is impossible to block an opening without a door to prevent water from passing through. Furthermore, in the water stop device disclosed in Patent Document 1, a watertight maintenance means (seal) is provided between the plate surface of the water stop plate and the door stop of the door frame. Also, in the water stop device disclosed in Patent Document 2, a watertight maintenance means (packing (sealing material)) is provided between the first part and each door stop. Therefore, in the water stop devices disclosed in these Patent Documents 1 and 2, there will be two members, namely the watertight maintenance means and the plate material, which do not originally exist, outside the door stop of the door frame. As a result, the door cannot be returned to its original closed state, and there is a risk of hindering the original functions of the door, such as the opening and closing operation and the locking operation of the door. That is, according to the water stop devices disclosed in Patent Documents 1 and 2, there is a problem that it may be impossible to block an opening without a door to prevent water from passing through, or there is a risk of hindering the original functions of the door.

[0005] In order to solve the above problems, the present invention provides a water stop device that can block an opening without a door and prevent water from passing through, and when installed to block the inner opening (opening) of a door frame to which a door is attached so as to be openable and closable, it is difficult to damage the door frame and it is difficult to impair the original function of the door.

Therefore, since it is characterized in this way, it is possible to block an opening without a door and prevent water from passing through, and when installed to block the inner opening of a door frame to which a door is attached so as to be openable and closable, it is possible to provide a water stop device that is difficult to damage the door frame and is difficult to impair the original function of the door. Also, when the water stop wall receives water pressure from, for example, the outdoor side, since the left locking portion and the right locking portion lock to the door stop surface of the door frame, it is possible to prevent, for example, the water stop device from falling into the indoor side. Also, The water stop device according to claim 2 is A lower locking portion is provided so as to extend from the lower end surface of the water stop wall and locks to the lower door stop surface of the inner opening of the door frame. part provided the Since the lower locking portion locks to the lower door stop surface and the lower water tightness maintaining means provided on the lower end surface of the water stop wall maintains water tightness between the lower end surface of the water stop wall and the lower surface of the inner opening of the door frame, when wall is For example, when receiving water pressure from the outdoor side, since the left locking portion, the right locking portion, and the lower locking portion lock to the door stop surface of the door frame, it is possible to suppress the water stop device from falling inward, for example. Furthermore, the water stop device according to claims 3 to 21 according to the present invention is a water stop device for closing an opening having a left surface, a right surface, and a lower surface and preventing water from passing through the opening. In addition to a configuration including a water stop wall, left watertight maintaining means provided on at least one of the left end surface of the water stop wall and the left surface of the opening to maintain watertightness between the left end surface of the water stop wall and the left surface of the opening, and a right end surface of the water stop wall and the right surface of the opening. Right watertight maintaining means provided on at least one of the right end surface of the water stop wall and the right surface of the opening to maintain watertightness between the lower end surface of the water stop wall and the lower surface of the opening. And lower watertight maintaining means provided on at least one of the lower end surface of the water stop wall and the lower surface of the opening, and is provided with each of the following configurations. In claim 3, The watertightness maintaining means is composed of sealing materials attached to the left end face, the right end face, and the lower end face of the water stop wall, which is the surface to be attached. The sealing materials are formed such that the thickness dimension from the surface to be attached where the sealing materials are attached gradually increases from the tip to the end when the water stop wall is inserted into the opening. Therefore, the attachment and detachment operations with respect to the opening are facilitated, and the watertightness maintaining function and the support function in the state where the water stop device is attached to the opening are improved. That is, a water stop device excellent in the watertightness maintaining function and the support function can be provided. In claim 4, The watertightness maintaining means is configured by combining a leaf spring and a sealing material. The leaf spring includes an attachment portion attached to the left end face, the right end face, and the lower end face of the water stop wall, which is the surface to be attached, and an elastic portion provided to extend from the attachment portion. The sealing material is attached to the elastic portion. When the water stop wall is inserted into the opening, the sealing material is pressed against the surface of the opening by the elastic force after the elastic portion of the leaf spring is deformed by receiving the force from the surface of the opening, and the watertightness between the surface of the opening and the sealing material is maintained. Therefore, a water stop device excellent in the watertightness maintaining function and the support function can be obtained by a simple attachment operation of inserting the water stop device into the opening. In claim 5, The watertightness maintaining means is configured by using a sealing material and a sealing material having water swelling performance.

Therefore, after the waterstop device is inserted into the opening, a simple attachment operation of filling the gap between the sealing material attached to the attachment surface of the waterstop wall and the surface of the opening with the sealing material having water swelling performance can obtain a waterstop device with excellent watertightness maintaining function and supporting function. In claim 6, The watertightness maintaining means is configured by using a sealing material and a sealing material having water swelling performance. When the waterstop wall is inserted into the opening, the sealing material is attached to the attachment surface of the waterstop wall so as to be biased toward the front side, which is the side opposite to the insertion direction, between the left end face, the right end face, and the lower end face of the waterstop wall, which are the attachment surfaces of the waterstop wall, and the surface of the opening. By filling the gap between the attachment surface of the waterstop wall inserted into the opening and the surface of the opening with the sealing material having water swelling performance from the rear side, the watertightness between the attachment surface of the waterstop wall and the surface of the opening is maintained. Therefore, after the waterstop wall is inserted into the opening and the sealing material is arranged on the front side between the attachment surface of the waterstop wall and the surface of the opening, a simple attachment operation of filling the gap between the attachment surface of the waterstop wall inserted into the opening and the surface of the opening with the sealing material having water swelling performance from the rear side can obtain a waterstop device with excellent watertightness maintaining function and supporting function. In claim 7, The watertightness maintaining means includes a mounting portion having a mounting surface mounted on the mounting surface of the watertight wall, and a folded-back portion extending from the mounting portion and having an outer surface that is folded back and faces the surface of the opening.

In this way, by adopting a configuration including a left water stop wall and a right water stop wall that are divided left and right, each water stop wall can be made compact, and a water stop device applicable to an opening with a relatively large left and right opening width can be provided. In addition, the attachment and detachment operation with respect to the opening becomes easy, and the watertight maintenance function and the support function in a state where the water stop device is attached to the opening are improved.

The wall plate portion 2a is formed by a rectangular flat plate having a plate surface that is orthogonal or substantially orthogonal to the front-rear direction. The left and right width dimensions of the plate surface that becomes the wall surfaces 21a and 21b of the wall plate portion 2a are formed to be slightly smaller than the dimension between the left surface 12 and the right surface 13 of the inner opening 11 of the door frame 10, and the upper and lower width dimensions of the plate surface (wall surfaces 21a and 21b) are formed to be smaller than the dimension between the lower surface 14 and the upper surface 15 of the inner opening 11 of the door frame 10, for example, about 1 / 4 to 1 / 2 of the dimension between the lower surface 14 and the upper surface 15. The left plate portion 2b is formed by a flat plate provided so as to extend forward from the left end edge of the wall plate portion 2a. The right plate portion 2c is formed by a flat plate provided so as to extend forward from the right end edge of the wall plate portion 2a.

That is, the left locking portion 6 is a portion formed by a flat plate provided so as to extend leftward from the front edge of the left plate portion 2b and is locked to the door stop surface 16 on the left side of the door frame 10. The right locking portion 7 is provided so as to extend from the right end face 23. That is, the right locking portion 7 is a portion formed by a flat plate provided so as to extend rightward from the front edge of the right plate portion 2c and is locked to the door stop surface 17 on the right side of the door frame 10. The lower locking portion 8 is provided so as to extend from the lower end face 24. That is, the lower locking portion 8 is a portion formed by a flat plate provided so as to extend downward from the front edge of the lower plate portion 2d and is locked to the door stop surface 18 on the lower side of the door frame 10.

[0013] In addition, the water stop wall 2 is formed such that, for example, the wall surfaces 21a, 21b of the wall plate portion 2a and the plate surfaces of the left plate portion 2b, the right plate portion 2c, the lower plate portion 2d, and the upper plate portion 2e are perpendicular or substantially perpendicular to each other, the plate surface of the left plate portion 2b and the plate surface of the left locking portion 6 are perpendicular or substantially perpendicular to each other, the plate surface of the right plate portion 2c and the plate surface of the right locking portion 7 are perpendicular or substantially perpendicular to each other, and the plate surface of the lower plate portion 2d and the plate surface of the lower locking portion 8 are perpendicular or substantially perpendicular to each other.

[0014] The water stop wall 2 is formed of, for example, a metal plate such as a steel plate or an aluminum plate, a synthetic resin plate, or the like. The manufacturing method of the water stop wall 2 is not particularly limited. For example, the wall plate portion 2a, the left plate portion 2b having the left locking portion 6 bent at the front end side, the right plate portion 2c having the right locking portion 7 bent at the front end side, the lower plate portion 2d having the lower locking portion 8 bent at the front end side, and the upper plate portion 2e are prepared separately, and these are manufactured by performing joining processes such as welding or other joining means, or a filling process S (see FIG. 6) of filling a filler such as a sealing agent into the joined portion after the joining process is performed. Also, after forming plates in which these parts are developed, the boundaries of the parts may be bent for manufacturing. In this case, at least the boundary between the lower plate portion 2d and the left plate portion 2b and the boundary between the lower plate portion 2d and the right plate portion 2c are subjected to a joining process such as welding or other joining means, or a filling process S (see FIG. 6) of filling a filler such as a sealing agent, or the filling process S is performed on the joined portion after the joining process.

[0015] The left watertight maintenance means 3 is a member provided on the left end surface 22 of the water stop wall 2, contacting the left surface 12 of the inner opening 11 of the door frame 10 and maintaining watertightness between the left surface 12. The right watertight maintenance means 4 is a member provided on the right end surface 23 of the water stop wall 2, contacting the right surface 13 of the inner opening 11 of the door frame 10 and maintaining watertightness between the right surface 13. The lower watertight maintenance means 5 is a member provided on the lower end surface 24 of the water stop wall 2, contacting the lower surface 14 of the inner opening 11 of the door frame 10 and maintaining watertightness between the lower surface 14.

[0016] The left end surface 22 of the water stop wall 2 which is the surface to be attached with the left watertight maintenance means 3 is formed by the outer plate surface of the left plate portion 2b. For example, the attachment surface of the flat left watertight maintenance means 3 having a plate surface with a size slightly smaller than the size of the left end surface 22 is attached to the left end surface 22 of the water stop wall 2 which is the surface to be attached with an adhesive or the like. The right end face 23 of the water stop wall 2, which is the surface to which the right water-tight maintenance means 4 is attached, is formed by the outer plate surface of the right plate portion 2c. For example, the mounting surface of the flat right water-tight maintenance means 4, which has a plate surface that is slightly smaller in size than the size of the right end face 23, is attached to the right end face 23 of the water stop wall 2 serving as the surface to be attached with an adhesive or the like. The lower end face 24 of the water stop wall 2, which is the surface to which the lower water-tight maintenance means 5 is attached, is formed by the outer plate surface of the lower plate portion 2d. For example, the mounting surface of the flat lower water-tight maintenance means 5, which has a plate surface that is slightly smaller in size than the size of the lower end face 24, is attached to the lower end face 24 of the water stop wall 2 serving as the surface to be attached with an adhesive or the like.

[0017] In addition, the lower end face of the left water-tight maintenance means 3 and the lower end face of the right water-tight maintenance means 4 are configured to contact the lower surface 14 of the inner opening 11 of the door frame 10 and maintain the water-tight performance between them. At the same time, the left end face of the lower water-tight maintenance means 5 and the left water-tight maintenance means 3 are provided so as to be in close contact, and the right end face of the lower water-tight maintenance means 5 and the right water-tight maintenance means 4 are provided so as to be in close contact. Alternatively, the lower end face of the lower water-tight maintenance means 5 is configured to contact the lower surface 14 of the inner opening 11 of the door frame 10 and maintain the water-tight performance between them. At the same time, the lower end face of the left water-tight maintenance means 3 and the lower water-tight maintenance means 5 are provided so as to be in close contact, and the lower end face of the right water-tight maintenance means 4 and the lower water-tight maintenance means 5 are provided so as to be in close contact.

[0018] As the water-tight maintenance means 3, 4, and 5, for example, a rubber sealing material such as EPDM rubber sponge (ethylene propylene rubber) or a sealing material having water swelling performance may be used, but a sealing material formed of other materials may also be used.

[0019] The water stop device 1 according to Embodiment 1 is configured such that the left locking portion 6 locks to the left door contact surface 16, and the left watertight maintaining means 3 provided on the left end surface 22 of the watertight wall 2 maintains watertightness between the left surface 12 of the door frame 10. Also, the right locking portion 7 locks to the right door contact surface 17, and the right watertight maintaining means 4 provided on the right end surface 23 of the watertight wall 2 maintains watertightness between the right surface 13 of the door frame 10. Further, the lower locking portion 8 locks to the lower door contact surface 18, and the lower watertight maintaining means 5 provided on the lower end surface 24 of the watertight wall 2 maintains watertightness between the lower surface 14 of the door frame 10. In addition, in the door frame 10 illustrated in Embodiment 1, the left surface 12, right surface 13, lower surface 14, and upper surface 15 of the inner opening 11 of the door frame 10 are surfaces on the rear side (indoors side) with respect to the door contact surfaces 16, 17, 18, 19.

[0020] According to the water stop device 1 of Embodiment 1, the left and right width of the water stop device 1, that is, the dimension of the interval between the left outer surface (outer plate surface) of the left watertight maintaining means 3 provided on the left end surface 22 of the watertight wall 2 and the right outer surface (outer plate surface) of the right watertight maintaining means 4 provided on the right end surface 23 of the watertight wall 2, is formed to be slightly larger than the left and right width of the opening of the door frame 10, that is, the dimension of the interval between the left surface 12 and the right surface 13 of the inner opening 11 of the door frame 10. By bringing the left outer surface of the left watertight maintaining means 3 provided on the left end surface 22 of the watertight wall 2 into close contact with the left surface 12 of the door frame 10, bringing the right outer surface of the right watertight maintaining means 4 provided on the right end surface 23 of the watertight wall 2 into close contact with the right surface 13 of the door frame 10, and bringing the lower outer surface of the lower watertight maintaining means 5 provided on the lower end surface 24 of the watertight wall 2 into close contact with the lower surface 14 of the door frame 10, the water stop device 1 is attached in a state of being fixed to the left surface 12, right surface 13, lower surface 14, and upper surface 15 of the inner opening 11 of the door frame 10. Therefore, when water W is pushed from the front side (outdoors side) of the water stop device 1 attached to the door frame 10 in a fixed state, the watertight maintaining means 3, 4, 5 can prevent the intrusion of water W to the rear side (indoors side) of the water stop device 1.

[0021] Further, when the wall plate portion 2a of the water stop wall 2 receives the water pressure from the front side (outdoor side) of the water stop device 1, the left locking portion 6, the right locking portion 7, and the lower locking portion 8 lock to the door contact surfaces 16, 17, and 18 of the door frame 10, so that the water stop device 1 can be prevented from falling backward (indoorside). In addition, as shown in Fig. 3(b), after the water stop device 1 is fixedly attached to the inner opening 11 of the door frame 10, in the state where the door 9 is closed, water W can enter the box-shaped space B of the water stop wall 2 through the gap L between the lower end surface 9a of the door 9 and the water drainage surface 14F located on the front side of the lower surface 14 of the door frame 10 facing the lower end surface 9a. In the water stop device 1 according to Embodiment 1, during flooding or the like, the flow of water W stops when the water head height on the front side (outdoor side) of the door 9 becomes the same as the water head height in the box-shaped space B of the water stop wall 2. In this case, the door 9 is in the same state as when it is immersed in water, and the door 9 can be easily opened, so that the door 9 can be opened and moved outdoors.

[0022] In addition, when a sealing material having water swelling performance is used as the watertight maintenance means 3, 4, and 5, after the water stop device 1 is attached to the door frame 10, by applying moisture to the sealing material having water swelling performance that constitutes these watertight maintenance means 3, 4, and 5, the sealing material expands, so that the watertight performance between the left surface 12, the right surface 13, and the lower surface 14 of the inner opening 11 of the door frame 10 can be improved.

[0023] According to the water stop device 1 according to Embodiment 1, by being attached so as to block the inner opening (opening portion) 11 of the door frame 10 to which the door 9 is attached so as to be openable and closable, the watertight maintenance means 3, 4, and 5 prevent water from entering the rear side (indoorside) of the water stop device 1. In addition, when the water stop device 1 is attached to the inner opening 11 of the door frame 10, the watertight maintenance means 3, 4, and 5 constituted by a sealing material having elasticity come into contact with the left surface 12, the right surface 13, and the lower surface 14 of the inner opening 11 of the door frame 10, so that the door frame 10 is hardly damaged. In addition, the left locking portion 6, the right locking portion 7, and the lower locking portion 8 are in direct contact with the door abutting surfaces 16, 17, and 18 of the door frame 10, and there is no member between the left locking portion 6, the left locking portion 6, the right locking portion 7, the lower locking portion 8 and the door abutting surfaces 16, 17, 18 of the door frame 10. Therefore, it becomes impossible to return the door 9 to its original closed state, and there is little possibility of hindering the original functions of the door such as the opening and closing operation and the locking operation of the door 9, and it is possible to provide the water stop device 1 that hardly impairs the original function of the door 9. In addition, even in an opening where the door 9 does not exist, by attaching it so as to maintain the watertightness between the watertightness maintaining means 3, 4, 5 of the water stop device 1 and the left surface 12, the right surface 13, and the lower surface 14 of the opening, it is possible to provide the water stop device 1 that can block the opening and prevent water from passing through.

[0024] Embodiment 2 In Embodiment 1, the water stop device 1 having a configuration in which the left watertightness maintaining means 3, the right watertightness maintaining means 4, and the lower watertightness maintaining means 5, which are separately configured, are attached to the left end surface 22, the right end surface 23, and the lower end surface 24 of the water stop wall 2 was exemplified. However, a water stop device 1 having a configuration in which the left watertightness maintaining means 3, the right watertightness maintaining means 4, and the lower watertightness maintaining means 5, which are integrally formed, are attached to the left end surface 22, the right end surface 23, and the lower end surface 24 of the water stop wall 2 may be used. In addition, similarly in each of the embodiments described later, the left watertightness maintaining means 3, the right watertightness maintaining means 4, and the lower watertightness maintaining means 5 may be separately configured or integrally configured.

[0025] Embodiment 3 In the water stop device 1 according to Embodiment 1, although the configuration in which the watertight maintenance means 3, 4, and 5 constituted by flat seal members are attached to the left end face 22, the right end face 23, and the lower end face 24 of the water stop wall 2 which is the surface to be attached has been illustrated, in the water stop device 1 according to Embodiment 3, as shown in FIG. 4, the watertight maintenance means 3, 4, and 5 are constituted by seal members attached to the left end face 22, the right end face 23, and the lower end face 24 of the water stop wall 2 which is the surface to be attached, and the seal members constituting the watertight maintenance means 3, 4, and 5 are formed such that the thickness dimension from the surface to be attached of the water stop wall 2 to which the seal members are attached gradually increases from the tip side to the end side when the water stop wall 2 is inserted into the inner opening (opening) 11 from the front side (outdoor side). As shown in FIG. 4, the tip side described in Embodiment 3 is the rear side (indoor side) of the opening, and the end side is the front side (outdoor side) of the opening.

[0026] For example, the seal members constituting the watertight maintenance means 3, 4, and 5 are formed such that the surfaces in contact with the left face 12, the right face 13, and the lower face 14 of the inner opening 11 of the door frame 10 are inclined surfaces so that the thickness dimension from the left end face 22, the right end face 23, and the lower end face 24 which are the surfaces to be attached to the seal members constituting the watertight maintenance means 3, 4, and 5 gradually increases from the tip side to the end side when the water stop wall 2 is inserted into the inner opening (opening) 11 from the front side (outdoor side). FIG. 4(a) shows the watertight maintenance means 5 in which the surface in contact with the lower face 14 of the inner opening 11 of the door frame 10 is formed as an inclined surface 5a so that the thickness dimension from the lower end face 24 of the water stop wall 2 which is the surface to be attached gradually increases from the tip side to the end side as described above. FIG. 4(b) shows the left watertight maintenance means 3 in which the surface in contact with the left face 12 of the inner opening 11 of the door frame 10 is formed as an inclined surface 3a so that the thickness dimension from the left end face 22 of the water stop wall 2 which is the surface to be attached gradually increases from the tip side to the end side as described above. Although not shown, similarly, in the right watertight maintenance means 4, the surface in contact with the right face 13 of the inner opening 11 of the door frame 10 is formed as an inclined surface so that the thickness dimension from the right end face 23 of the water stop wall 2 which is the surface to be attached gradually increases from the tip side to the end side as described above.

[0027] Further, as shown in FIGS. 4(c) and 4(d), the sealing materials constituting the watertight maintenance means 3, 4, and 5 project obliquely rearward (toward the end side) from a plane that becomes a facing surface parallel to the planar mounting surface mounted on the mounted surface, in the front-to-rear direction (from the tip to the end), such that the thickness dimensions from the left end surface 22, right end surface 23, and lower end surface 24, which are the mounted surfaces on which the sealing materials constituting the watertight maintenance means 3, 4, and 5 are mounted, gradually increase from the tip side to the end side when the watertight wall 2 is inserted into the inner opening (opening) 11 from the front side (outdoor side). A plurality of sickle-shaped protruding pieces are provided at intervals along the front-to-rear direction (from the tip to the end), and the protruding pieces provided on the rear side (end side) are formed such that the protruding amount and size are larger. FIG. 4(c) shows the left-side watertight maintenance means 5 configured such that a plurality of sickle-shaped protruding pieces 5d projecting obliquely rearward (toward the end side) from a plane that becomes a facing surface 5c parallel to the planar mounting surface 5b mounted on the lower end surface 24 are provided at intervals along the front-to-rear direction (from the tip to the end), and the thickness dimension from the lower end surface 24, which is the mounted surface on which the watertight maintenance means 5 is mounted, gradually increases from the tip side to the end side as described above, and the protruding pieces 5d provided on the rear side (end side) have a larger protruding amount and size. FIG. 4(d) shows the lower-side watertight maintenance means 3 configured such that a plurality of sickle-shaped protruding pieces 3d projecting obliquely rearward (toward the end side) from a plane that becomes a facing surface 3c parallel to the planar mounting surface 3b mounted on the left end surface 22 are provided at intervals along the front-to-rear direction (from the tip to the end), and the thickness dimension from the left end surface 22, which is the mounted surface on which the watertight maintenance means 3 is mounted, gradually increases from the tip side to the end side as described above, and the protruding pieces 3d provided on the rear side (end side) have a larger protruding amount and size.

[0028] According to the waterstop device 1 according to Embodiment 3 provided with the watertight maintenance means 3, 4, and 5 configured such that the thickness dimension from the mounted surface gradually increases from the tip side to the end side as described above, the attachment / detachment operation with respect to the inner opening 11 of the door frame 10 becomes easy, and the watertight maintenance function and support function in the state where the waterstop device 1 is mounted on the door frame 10 are improved. That is, a waterstop device 1 excellent in watertight maintenance function and support function can be provided.

[0029] Embodiment 4 As shown in FIG. 5, in the water stop device 1 according to Embodiment 3, the sealing materials constituting the watertight maintenance means 3, 4, and 5 have an attachment portion 30A having an attachment surface 30a attached to the attachment surfaces (left end surface 22, right end surface 23, lower end surface 24) of the water stop wall 2, and a folded-back portion 30B having an outer surface 30b that extends from the attachment portion 30A and is folded back to face the surfaces (left surface 12, right surface 13, lower surface 14) of the inner opening 11 of the door frame 10. The groove 30 is formed to be surrounded by the opposing surfaces 30c of the attachment portions 30A facing each other, the opposing surfaces 30d of the folded-back portions 30B, and the surface 30e of the boundary portion between the attachment portion 30A and the folded-back portion 30B extending from these opposing surfaces 30c and 30d. Furthermore, a pressing means 31 is provided which is fitted into the groove 30 of the watertight maintenance means and presses the outer surface 30b of the folded-back portion 30B of the watertight maintenance means 3, 4, and 5 against the surface of the inner opening 11 of the door frame 10.

[0030] The pressing means 31 is formed in a shape whose cross-sectional shape is larger than the cross-sectional shape of the groove 30 of the watertight maintenance means 3, 4, and 5, and includes a reference surface 32 that contacts the opposing surface 30c of the attachment portion 30A and a pressing surface 33 that contacts the opposing surface 30d of the folded-back portion 30B and presses the outer surface 30b of the folded-back portion 30B against the surface of the inner opening 11 of the door frame 10. For example, it may be a fitting member such as a wedge that is fitted into the groove 30.

[0031] According to the water stop device 1 according to Embodiment 4, the water stop device 1 is installed so that the outer surfaces of the watertight maintenance means 3, 4, and 5 face the respective surfaces (left surface 12, right end surface 13, lower end surface 14) of the inner opening 11 of the door frame 10. With the locking portions 6, 7, and 8 in contact with the door stop surfaces 16, 17, and 18, by fitting the pressing means 31 into the groove 30 of the watertight maintenance means 3, 4, and 5, the outer surface 30b of the folded-back portion 30B of the watertight maintenance means 3, 4, and 5 is pressed against the respective surfaces of the inner opening 11 of the door frame 10. Thus, the water stop device 1 is supported by the respective surfaces of the inner opening 11 of the door frame 10, and a configuration is achieved in which the watertightness between the watertight maintenance means 3, 4, and 5 and the respective surfaces of the inner opening 11 is maintained well.

[0032] In FIG. 5, a watertight maintenance means in which the left watertight maintenance means 3, the right watertight maintenance means 4, and the lower watertight maintenance means 5 are integrally formed is attached to the left end face 22, the right end face 23, and the lower end face 24 of the water stop wall 2. Further, as the pressing means 31, an example is shown in which a linear groove corresponding pressing means 31A for a portion where the groove 30 extends linearly and a corner groove corresponding pressing means 31B for a portion where the groove 30 extends in an L shape are used. Thus, in the case of a configuration in which an integral watertight maintenance means is used and the linear groove corresponding pressing means 31A and the corner groove corresponding pressing means 31B are used as the pressing means 31, by using the corner groove corresponding pressing means 31B, the watertight performance between the inner corner portion, which is the boundary between the left surface 12 and the lower surface 14 of the door frame 10, and the watertight maintenance means, and the watertightness between the inner corner portion, which is the boundary between the right surface 13 and the lower surface 14 of the door frame 10, and the watertight maintenance means can be maintained well.

[0033] In Embodiment 4, a configuration may be adopted in which separate left watertight maintenance means 3, right watertight maintenance means 4, and lower watertight maintenance means 5 are used. In this case, as the pressing means, the linear groove corresponding pressing means 31A may be used, and there is no need to use the corner groove corresponding pressing means 31B. In addition, the pressing means 31 preferably includes a handle portion 34 as in the linear groove corresponding pressing means 31A shown in FIG. 5. When the handle portion 34 is provided, the pressing means 31 can be removed from the groove 30 of the watertight maintenance means 3, 4, 5 by holding the handle portion 34, and the removal work can be easily performed. Further, in FIG. 5, the corner groove corresponding pressing means 31B without the handle portion 34 is shown, but the corner groove corresponding pressing means 31B also preferably includes the handle portion 34.

[0034] According to the water stop device 1 according to Embodiment 4, the attachment / detachment operation with respect to the inner opening 11 of the door frame 10 is facilitated, and the watertight maintenance function and the support function in the state where the water stop device 1 is attached to the door frame 10 are improved. That is, a water stop device 1 excellent in watertight maintenance function and support function can be provided.

[0036] For example, as shown in Fig. 6, the support mechanism 40 includes a pressing body 41 provided so as to be movable in a direction perpendicular to the left and right surfaces 12, 13 of the inner opening of the door frame, a transfer means 42 for moving the pressing body 41 in a direction perpendicular to the left and right surfaces 12, 13 of the inner opening 11 of the door frame 10, and a reaction force transmission means 43 for transmitting the reaction force when the pressing body 41 presses the left surface 12 or the right surface 13 of the inner opening 11 of the door frame 10 to the water stop wall 2.

[0037] The transfer means 42 is composed of a female screw hole 45 formed in a support piece 44 provided so as to extend upward from the left end of the upper plate portion 2e of the water stop wall 2, and a screw 46 screwed into the female screw hole 45 and configured to be movable in the left - right direction. A pressing body 41 is provided at the left end which is the tip of the screw 46 screwed into the female screw hole 45, and an operation handle 46a is provided at the right end which is the end of the screw 46 screwed into the female screw hole 45. The pressing body 41, similar to the left side of the water stop wall 2, includes a plate portion 47 having a left plate portion 47a and a left - side locking portion 47b, and a support 48 provided on the outer surface of the left plate portion 47a. The support 48 is preferably formed of a material harder than the above - described sealing material, for example, a material such as hard rubber which has relatively high rigidity and is less likely to damage the surface. The reaction force transmission means 43 is composed of the above - described screw 46 and a support piece 44 provided so as to extend from the water stop wall 2 and having a female screw hole 45 into which the screw 46 is screwed.

[0038] According to the water stop device 1 according to Embodiment 5, when the operation handle 46a is operated and the pressing body 41 presses the left surface 12 of the inner opening 11 of the door frame 10, the watertight maintenance means 4 on the right side of the water stop wall 2 is pressed against the right surface 13 of the inner opening 11 of the door frame 10 by the reaction force when the pressing body 41 presses the left surface 12 of the inner opening 11 of the door frame 10, or the pressing body 41 presses the right surface 13 of the inner opening 11 of the door frame 10, and the watertight maintenance means 3 on the left side of the water stop wall 2 is pressed against the left surface 12 of the inner opening 11 of the door frame 10 by the reaction force when the pressing body 41 presses the right surface 13 of the inner opening 11 of the door frame 10. Thus, the water stop wall 2 is supported by the left and right surfaces 12 and 13 of the inner opening 11 of the door frame 10, so that the support function for supporting the water stop wall 2 is improved. That is, the support function in the state where the water stop device 1 is attached to the inner opening 11 of the door frame 10 is improved. In other words, a water stop device 1 with excellent support function can be provided.

[0039] The water stop device 1 according to Embodiment 5 may be configured to include the above-described support mechanisms 40 on the left side and the right side at the upper part of the water stop wall 2, respectively. In this case, the water stop wall 2 is supported by the left and right surfaces 12 and 13 of the inner opening 11 of the door frame 10 via the left and right pressing bodies 41 and 41.

[0040] Embodiment 6 In the case of the water stop device 1 according to Embodiment 5, in order to enhance the support function for supporting the water stop wall 2, if the pressing body 41 of the support mechanism 40 presses the surface of the inner opening 11 of the door frame 10 too much, there is a possibility that the watertight performance between the watertight maintenance means 3 and 4 and the left and right surfaces 12 and 13 of the inner opening 11 of the door frame 10 cannot be maintained. Therefore, in the water stop device 1 according to Embodiment 6, the water stop device 1 is configured such that the support function for supporting the water stop wall 2 can be improved and the watertight performance maintenance function can also be improved.

[0041] That is, as shown in FIG. 7, the water stop device 1 according to Embodiment 6 includes a support mechanism 50 connected to the upper part of the water stop wall 2. The support mechanism 50 includes a horizontal support mechanism 50A for supporting the water stop wall 2 on the left and right surfaces 12 and 13 of the inner opening 11 of the door frame 10, and a vertical support mechanism 50B for supporting the water stop wall on the lower surface of the inner opening of the door frame. When the water stop wall 2 is supported on the left and right surfaces 12 and 13 of the inner opening 11 of the door frame 10 by the horizontal support mechanism 50A, among the watertight maintenance means 3 on the left side and the watertight maintenance means 4 on the right side of the water stop wall 2, the watertight maintenance means that is not pressed against the surface of the inner opening 11 of the door frame 10, for example, the watertight maintenance means 3 on the left side in FIG. 7(a) has the same configuration as the configuration described in Embodiment 4 (FIG. 5). That is, when the water stop wall 2 is supported on the left and right surfaces 12 and 13 of the inner opening 11 of the door frame 10 by the horizontal support mechanism 50A, among the watertight maintenance means 3 on the left side and the watertight maintenance means 4 on the right side of the water stop wall 2, the watertight maintenance means that is not pressed against the surface of the inner opening 11 of the door frame 10 has, for example, the same configuration as the watertight maintenance means 3, 4, and 5 in FIG. 5. It has an attachment portion 30A having an attachment surface 30a attached to the attachment surfaces (left end surface 22, right end surface 23, lower end surface 24) of the water stop wall 2, and a folded-back portion 30B having an outer surface 30b that extends from the attachment portion 30A and is folded back to face the surface of the inner opening 11 of the door frame 10. It is configured to include a groove 30 formed by being surrounded by the opposing surfaces 30c of the opposing attachment portions 30A, the opposing surfaces 30d of the folded-back portion 30B, and the surfaces 30e of the boundary portions between the attachment portion 30A and the folded-back portion 30B extending from these opposing surfaces 30c and 30d. Also, it is configured to include a pressing means 31C (see FIG. 7(b)) having the same configuration as the above-described linear groove corresponding pressing means 31A that is fitted into the groove 30 of the watertight maintenance means and presses the outer surface 30b of the folded-back portion 30B of the watertight maintenance means against the surface of the inner opening 11 of the door frame 10.

[0042] Further, when the water stop wall 2 is supported by the horizontal support mechanism 50A on the left and right surfaces 12 and 13 of the inner opening 11 of the door frame 10, if the water tightness maintaining means that is not pressed against the surface of the inner opening 11 of the door frame 10 among the water tightness maintaining means 3 on the left side and the water tightness maintaining means 4 on the right side of the water stop wall 2 is, for example, the left water tightness maintaining means 3 shown in FIG. 7(a), as shown in FIG. 7(b), the groove 30 may be formed by a groove 30 having a V-shaped cross section or a U-shaped cross section by a leaf spring 35 having a V-shaped cross section or a U-shaped cross section. That is, the water tightness maintaining means that is not pressed against the surface of the inner opening 11 of the door frame 10 among the water tightness maintaining means 3 and the water tightness maintaining means 4 on the right side may be a water tightness maintaining means having a configuration in which a leaf spring 35 and a sealing material 36 are combined. In addition, in FIG. 7(b), the same reference numerals are given to the same parts or corresponding parts as those described in FIG. 5, and the detailed description thereof is omitted. In this case, the mounting portion 30A is constituted by one plate portion 35a of a V-shape or U-shape of a leaf spring 35 having a mounting surface 30a mounted on the surface of the water stop wall 2, and the folding portion 30B is extended from the mounting portion 30A and folded back, and the other plate portion 35b of the V-shape or U-shape of the leaf spring 35 and a sealing material 36 having an outer surface 30b mounted on the outer plate surface of the other plate portion 35b and facing the surface of the inner opening 11 of the door frame 10. As the sealing material 36, for example, the same sealing material as the water tightness maintaining means 3, 4, and 5 described in the first embodiment may be used. Further, the leaf spring 35 is formed of, for example, metal, synthetic resin, etc., and when a force is applied to one plate portion and the other plate portion of the V-shape or U-shape, due to the elasticity of the bent portion which is the boundary portion between one plate portion and the other plate portion of the V-shape or U-shape, one plate portion and the other plate portion of the V-shape or U-shape are configured to be urged in a direction in which they separate from each other.

[0043] The horizontal support mechanism 50A is configured to include a telescopic member 51 configured to be able to expand and contract in a direction orthogonal to the left and right surfaces 12 and 13 of the inner opening 11 of the door frame 10, and a reaction force transmission means 52.

[0044] In this case, the telescopic member 51 includes, for example, a fixed-length member 51A provided such that one end thereof contacts either the left surface 12 or the right surface 13 of the inner opening 11 of the door frame 10, and a pressing mechanism 51B provided at the other end side of the fixed-length member 51A so as to be movable in a direction orthogonal to the left and right surfaces 12 and 13 of the inner opening 11 of the door frame 10. The fixed-length member 51A is formed of a pipe material such as a metal pipe having a quadrangular cross section, for example. The pressing mechanism 51B has the same configuration as the support mechanism 40 described above. For example, as shown in FIG. 7(a), the pressing mechanism 51B includes a support piece 51a provided so as to extend upward from the other end side of the fixed-length member 51A, a female screw hole 51b formed in the support piece 51a, a screw 51c screwed into the female screw hole 51b and configured to be movable in the left-right direction, and a pressing body 51d provided at the tip of the screw 51c screwed into the female screw hole 51b and contacting either one of the left and right surfaces 12 and 13 of the inner opening 11 of the door frame 10. The pressing body 51d is preferably formed of a material harder than the sealing material, for example, a material such as hard rubber that has relatively high rigidity and is less likely to damage the surface. In addition, at least one end of the fixed-length member 51A on the side opposite to the side where the pressing mechanism 51B is provided is provided with a contact portion 51f that contacts the other of the left and right surfaces 12 and 13 of the inner opening 11 of the door frame 10. The contact portion 51f is preferably formed of a material harder than the sealing material, for example, a material such as hard rubber that has relatively high rigidity and is less likely to damage the surface, similar to the pressing body 51d.

[0045] The reaction force transmission means 52 is a means that functions to transmit the reaction force when the pressing body 51d presses either the left surface 12 or the right surface 13 of the inner opening 11 of the door frame 10 to the water stop wall 2, and is constituted by, for example, bolts 53 and nuts 54 that connect the telescopic member 51 and the upper plate portion 2e of the water stop wall 2 in a fixed state.

[0046] The vertical support mechanism 50B is configured to include the aforementioned telescopic member 51 attached so as to stretch between the left and right surfaces 12 and 13 of the inner opening 11 of the door frame 10, and a pressing mechanism 55 provided so as to be movable in the vertical direction with respect to the fixed length member 51A of the telescopic member 51. For example, as shown in FIG. 7(a), the pressing mechanism 55 includes a female screw hole 55a formed in the fixed length member 51A of the aforementioned telescopic member 51, a screw 55b screwed into the female screw hole 55a and configured to be movable in the vertical direction, and a pressing body 55c provided at the lower end which is the tip of the screw 55b screwed into the female screw hole 55a and contacting the upper surface of the upper plate portion 2e of the water stop wall 2.

[0047] According to the water stop device 1 according to Embodiment 6, after installing the water stop device 1 so that the outer surfaces of the watertight maintenance means 3, 4, and 5 face the respective surfaces of the inner opening 11 of the door frame 10, first, the horizontal support mechanism 50A is operated. For example, by operating the horizontal support mechanism 50A shown in FIG. 7(a), the telescopic member 51 is stretched between the left and right surfaces 12 and 13 of the inner opening 11 of the door frame 10, and the water stop wall 2 is supported by the left and right surfaces 12 and 13 of the inner opening 11 of the door frame 10. When operating the horizontal support mechanism 50A, the bolt 53 and nut 54 constituting the reaction force transmission means 52 are tightened to connect and fix the telescopic member 51 and the water stop wall 2 in a fixed state. Next, with the bolt 53 and nut 54 loosened, the vertical support mechanism 50B is operated. That is, by turning the screw 55b to move the pressing body 55c downward to press and move the water stop wall 2 downward, the water stop wall 2 is supported by the lower surface 14 of the inner opening 11 of the door frame 10. Thereafter, by fitting the pressing means 31C into the groove 30 of the left watertight maintenance means 3 shown in FIG. 7, for example, the outer surface 30b of the folded-back portion 30B of the watertight maintenance means 3 is pressed against the left surface 12 of the inner opening 11 of the door frame 10 (see FIG. 7(b)). As described above, the water stop device 1 is supported by the respective surfaces 12, 13, and 14 of the inner opening 11 of the door frame 10, and the watertight performance between the watertight maintenance means 3, 4, and 5 and the respective surfaces 12, 13, and 14 of the inner opening 11 is maintained.

[0048] That is, in the water stop device 1 according to Embodiment 6, instead of the support mechanism 40 of Embodiment 5, a support mechanism 50 having a horizontal direction support mechanism 50A and a vertical direction pressing mechanism 50B is provided. Moreover, as the watertight maintenance member on the side where the watertight performance between the watertight maintenance member and the surface becomes weak, a watertight maintenance means having the same configuration as the watertight maintenance means shown in Embodiment 4 is provided, and a pressing means 31C that is fitted into the groove 30 of the watertight maintenance means and presses the outer surface 30b of the folded-back portion 30B against the surface of the inner opening 11 of the door frame 10 is provided. Therefore, the attachment / detachment operation with respect to the inner opening 11 of the door frame 10 becomes easy, and the watertight maintenance function and the support function in the state where the water stop device 1 is attached to the door frame 10 are further improved. That is, a water stop device 1 excellent in the watertight maintenance function and the support function can be provided. In particular, since the vertical direction support mechanism 50B is provided, the support function of the lower surface 14 of the inner opening 11 of the door frame 10 with respect to the water stop device 1 can be improved, and the water stop device 1 can be fixed more firmly to the inner opening 11 of the door frame 10.

[0049] Embodiment 7 As shown in FIG. 8, the water stop device 1 according to Embodiment 7 has a configuration in which the water stop wall 2 includes a left water stop wall 2A and a right water stop wall 2B that are divided left and right, and a coupling means 60 that couples the right end side portion of the left water stop wall 2A and the left end side portion of the right water stop wall 2B is provided.

[0050] The right water stop wall 2B, for example, as shown in FIG. 8(a), has a shorter left-right width compared to the water stop wall 2 shown in FIG. 2 of Embodiment 1, and does not include the left locking portion 6 and the left watertight maintenance means 3, and has a configuration including the right watertight maintenance means 4 and the lower watertight maintenance means 5b. The lower watertight maintenance means 5b has the same configuration as the above-described lower watertight maintenance means 5.

[0051] The left water stop wall 2A is a wall extending in the vertical direction, comprising an opposing plate portion 71 formed by a flat plate having an opposing surface 70 facing the left end surface 22A of the right water stop wall 2B, a left locking portion 6 formed by a flat plate provided so as to extend to the left from the front edge of the opposing plate portion 71, and a rear plate portion 73 formed by a flat plate provided so as to extend to the right from the rear edge of the opposing plate portion 71 and having an opposing surface 72 facing the wall surface 21b on the rear side of the wall plate portion 2a of the right water stop wall 2B. And a rear watertight maintenance means 75 formed of a flat sealing material or the like is attached to substantially the entire surface of the opposing surface 72, and a left watertight maintenance means 3 is provided on substantially the entire surface of the left end surface 70a which is the surface on the side opposite to the opposing surface 70 of the opposing plate portion 71. Further, for example, a watertight maintenance means 5a similar to the lower watertight maintenance means 5 is attached to the lower end surfaces of these components so as to cover the lower end surfaces of the opposing plate portion 71, the rear plate portion 73, the rear watertight maintenance means 75, and the left watertight maintenance means 3. That is, the left end surface 70a of the opposing plate portion 71 functions as the left end surface 22 of the water stop wall 2 in Embodiment 1.

[0052] The coupling means 60 is means for applying a lateral force to the opposing surfaces 22A and 70 of the right end side portion of the left water stop wall 2A and the left end side portion of the right water stop wall 2B, respectively, and pressing the left watertight maintenance means 3 of the left water stop wall 2A and the right watertight maintenance means 4 of the right water stop wall 2B against the surfaces 12 and 13 of the inner opening 11 of the opposing door frame 10. The coupling means 60 is composed of, for example, as shown in FIG. 8, a fixed wedge 61 fixed to the left end surface 22A of the right water stop wall 2B, and a fitting wedge 62 fitted between the opposing surface 70 of the opposing plate portion 71 of the left water stop wall 2A facing the left end surface 22A of the right water stop wall 2B and the fixed wedge 61. The fitting wedge 62 is preferably connected to the water stop wall 2 by a connecting string 63 to prevent loss.

[0053] According to the water stop device 1 according to Embodiment 7, first, the outer surface of the watertight maintenance means 4 on the right side of the right water stop wall 2B is opposed to the right surface 13 of the inner opening 11 of the door frame 10, and the outer surface of the watertight maintenance means 3 on the left side of the left water stop wall 2A is opposed to the left surface 12 of the inner opening 11 of the door frame 10. Then, the rear wall surface 21b of the wall plate portion 2a of the right water stop wall 2B is brought into close contact with the rear watertight maintenance means 75 of the left water stop wall 2A, and the left water stop wall 2A and the right water stop wall 2B are pressed downward so that the lower surface of the lower watertight maintenance means 5a of the left water stop wall 2A and the lower surface of the lower watertight maintenance means 5b of the right water stop wall 2B are in close contact with the lower surface 14 of the inner opening 11 of the door frame 10. After that, an insertion wedge 62 is inserted between the fixed wedge 61 fixed to the left end surface 22A of the right water stop wall 2B and the opposing surface 70 of the left water stop wall 2A. As described above, as shown in Fig. 8(b), the watertightness between the rear wall surface 21b of the wall plate portion 2a of the right water stop wall 2B and the rear watertight maintenance means 75 of the left water stop wall 2A is maintained, and the watertightness between the watertight maintenance means 4 on the right side of the right water stop wall 2B and the right surface 13 of the inner opening 11 of the door frame 10, the watertightness between the watertight maintenance means 3 on the left side of the left water stop wall 2A and the left surface 12 of the inner opening 11 of the door frame 10, and the watertightness between the lower watertight maintenance means 5a of the left water stop wall 2A and the lower watertight maintenance means 5b of the right water stop wall 2B and the lower surface 14 of the inner opening 11 of the door frame 10 are maintained.

It is configured without the right locking portion 7 and the left - hand side watertight maintenance means 3, and includes the right - hand side watertight maintenance means 4 and the lower - side watertight maintenance means 5b. The lower - side watertight maintenance means 5b has the same configuration as the above - described lower - side watertight maintenance means 5. In other words, the right water stop wall 2D is configured without the right locking portion 7 of the above - described right water stop wall 2B.

In addition, the fitting wedges 62A and 62B are preferably connected to the water stop wall 2 by a connecting string 63 to prevent loss.

[0059] According to the water stop device 1 according to Embodiment 8, first, the outer surface of the watertight maintenance means 4 on the right side of the right water stop wall 2D is opposed to the right surface 13 of the inner opening 11 of the door frame 10, and the outer surface of the watertight maintenance means 3 on the left side of the left water stop wall 2C is opposed to the left surface 12 of the inner opening 11 of the door frame 10.

After that, an insertion wedge 62A is inserted between the fixing wedge 61A fixed to the left end surface 22A of the right water stop wall 2D and the opposing surface 80 of the left water stop wall 2C. Furthermore, an insertion wedge 62B is inserted between the fixing wedge 61B fixed to the left end side surface of the rear wall surface 21b of the right water stop wall 2D and the opposing surface 82 of the left water stop wall 2A.

[0060] That is, according to the water stop device 1 according to Embodiments 7 and 8, since the configuration includes the left water stop wall 2A and the right water stop wall 2B that are divided into left and right, each water stop wall can be made compact, and a water stop device 1 applicable to an opening with a relatively large left and right opening width can be provided. In addition, the attachment / detachment operation with respect to the inner opening 11 of the door frame 10 becomes easier, and the watertight maintenance function and the support function in a state where the water stop device 1 is attached to the door frame 10 are further improved. That is, a water stop device 1 excellent in the watertight maintenance function and the support function can be provided.

[0061] In addition, according to the water stop device 1 according to Embodiments 7 and 8, since the coupling means is constituted by the fixed wedge and the fitting wedge, the water stop device 1 can be fixedly attached to the inner opening 11 of the door frame 10 by a simple operation of fitting the fitting wedge, and by a simple operation of fitting the fitting wedge, the water stop device 1 can be fixedly attached to the inner opening 11 of the door frame 10, and the watertight maintenance function and the support function in a state where the water stop device 1 is attached to the inner opening 11 of the door frame 10 are improved.

That is, when the coupling means is constituted by the fixed wedge and the fitting wedge, the attachment / detachment operation with respect to the inner opening 11 of the door frame 10 becomes easier, and the watertight maintenance function and the support function in a state where the water stop device is attached to the inner opening 11 of the door frame 10 are improved.

[0062] In addition, in Embodiments 7 and 8, the configuration of the left water stop wall may be applied to the right water stop wall, and the configuration of the right water stop wall may be applied to the left water stop wall.

[0063] In Embodiment 8, one of the right end side portion of the left water stop wall and the left end side portion of the right water stop wall may be configured to include front and rear wall plates that sandwich the front and rear direction surfaces of the other of the right end side portion of the left water stop wall and the left end side portion of the right water stop wall.

[0064] In addition, in Embodiment 7 (FIG. 8), the water stop device 1 having a configuration without each locking portion may be used. In addition, in Embodiment 8 (FIG. 9), the water stop device 1 having a configuration with each locking portion may be used. In Embodiment 7 and Embodiment 8, by adopting the water stop device 1 configured without each locking portion, as described above, for example, it becomes the water stop device 1 applicable to openings such as the opening between the left and right guide rails of the shutter device, and openings constituting entrances and exits such as doors and walls.

[0065] Embodiment 9 As shown in FIG. 10, the water stop device 1 according to Embodiment 9 is configured to include watertight maintenance means 3, 4, and 5 in which a leaf spring 100 and a sealing material 110 are combined. Note that the watertight maintenance means 3 is illustrated in FIG. 10.

[0066] The leaf spring 100 uses a long member having, for example, a V-shaped cross section or a U-shaped cross section, which includes a mounting portion 101 attached to the left end face 22, the right end face 23, and the lower end face 24 of the water stop wall 2, which is the surface to be mounted of the water stop wall 2, and an elastic portion 102 provided so as to extend from the mounting portion 101. One plate portion of the V shape or U shape functions as the mounting portion 101, and the other plate portion of the V shape or U shape functions as the elastic portion 102. Then, the boundary between the mounting portion 101 and the elastic portion 102, that is, the bent portion 103, is located on the tip side when the water stop wall 2 is inserted into the inner opening 11 of the door frame 10, and the left end face 22, the right end face 23, the lower end face 24, which are the surfaces to be mounted of the water stop wall 2, and the outer surface 104 of the mounting portion 101 are adhered with an adhesive or the like. The sealing material 110 is formed in a plate shape, for example, and the plate surface of the plate-shaped sealing material 110 and substantially the entire outer surface 105 of the elastic portion 102 are adhered with an adhesive or the like. Note that the leaf spring 100 is formed of, for example, metal, synthetic resin, or the like, and when a force is applied to one plate portion and the other plate portion of the V shape or U shape, due to the elasticity of the bent portion, which is the boundary portion between one plate portion and the other plate portion of the V shape or U shape, one plate portion and the other plate portion of the V shape or U shape are configured to be biased in a direction in which they separate from each other. Also, for the sealing material 110, the same sealing material as the watertight maintenance means 3, 4, and 5 described in Embodiment 1 may be used, for example.

[0067] Based on FIG. 10, the watertight treatment by the watertight maintenance means 3 in the water stop device 1 according to Embodiment 9 will be described. First, as shown in Fig. 10(a), when inserting the water stop device 1 into the inner opening 11 of the door frame 10 from the front side (outdoor side), position the bent portion 103 of the leaf spring 100 constituting the watertight maintenance means 3 on the tip side in the insertion direction, and then insert the water stop device 1 into the inner opening 11 of the door frame 10 from the front side (outdoor side). When the sealing material 110 constituting the watertight maintenance means 3 contacts and is pressed against the left surface 12 of the inner opening 11 during this insertion, the elastic portion 102 of the leaf spring 100 deforms in a direction approaching the mounting portion 101 with the bent portion 103 as the rotation center under the force from the left surface 12 of the inner opening 11. Then, as shown in Fig. 10(b), the sealing material 110 is pressed against the left surface 12 of the inner opening 11 by the elastic force after the elastic portion 102 deforms, and the watertightness between the left surface 12 of the inner opening 11 and the sealing material 110 is maintained. It goes without saying that the watertight maintenance means 4 and 5 are also configured in the same manner as the above-described watertight maintenance means 3, and the same operational effects can be obtained.

[0068] According to the water stop device 1 according to Embodiment 9, a water stop device 1 excellent in watertight maintenance function and support function can be obtained by a simple mounting operation of inserting the water stop device 1 into the inner opening 11 of the door frame 10 from the front side (outdoor side).

[0069] Embodiment 10 As shown in Fig. 11, the water stop device 1 according to Embodiment 10 is configured to include watertight maintenance means 3, 4, and 5 using a sealing material 120 and a sealing material 130 having water swelling performance. In Fig. 11, the watertight maintenance means 3 is illustrated as an example.

[0070] As shown in Fig. 11(a), the sealing material 120 is attached to the left end surface 22, the right end surface 23, and the lower end surface 24, which are the surfaces to be mounted of the water stop wall 2, in a state where a gap R is generated between the sealing material 120 and the left surface 12 of the inner opening 11 when the water stop device 1 is inserted into the inner opening 11 of the door frame 10 from the front side (outdoor side). Then, as shown in Fig. 11(b), from the rear side (indoors side), a sealing material 130 having water swelling performance is filled in the gap R between the sealing material 120 attached to the mounting surface of the water stop wall 2 inserted into the inner opening 11 of the door frame 10 and the surface of the inner opening 11 of the door frame 10, so that the watertightness between the sealing material 120 and the surface of the inner opening 11 of the door frame 10 is maintained. Incidentally, as the sealing material 130 having water swelling performance, for example, a long anti-corrosive water swelling rubber having a circular cross-section may be used. Also, as the sealing material 120, for example, the same sealing material as the watertightness maintaining means 3, 4, 5 described in the first embodiment may be used.

[0071] Based on Fig. 11, the watertightness treatment by the watertightness maintaining means 3 in the water stop device 1 according to the tenth embodiment will be described. First, as shown in Fig. 11(a), the water stop device 1 is inserted into the inner opening 11 of the door frame 10 from the front side (outdoors side). At this time, a gap R is generated between the sealing material 120 attached to the left end surface 22 of the water stop wall 2 and the left surface 12 of the inner opening 11. After that, from the rear side (indoors side), as shown in Fig. 11(b), the sealing material 130 having water swelling performance is filled in the gap R, so that the watertightness between the sealing material 120 and the left surface 12 of the inner opening 11 of the door frame 10 is maintained. Incidentally, the watertightness maintaining means 4 and 5 are also configured in the same manner as the above-described watertightness maintaining means 3, and it goes without saying that the same operational effects can be obtained.

[0072] According to the water stop device 1 according to the tenth embodiment, after the water stop device 1 is inserted into the inner opening 11 of the door frame 10 from the front side (outdoors side), a simple mounting operation of filling the gap R generated between the sealing material 120 attached to the mounting surface of the water stop wall 2 and the surface of the inner opening 11 of the door frame 10 with the sealing material 130 having water swelling performance from the rear side (indoors side) can obtain a water stop device 1 excellent in watertightness maintaining function and support function.

[0073] Embodiment 11 As shown in Fig. 12, the water stop device 1 according to Embodiment 11 has a configuration provided with watertight maintenance means 3, 4, and 5 using a sealing material 120 and a sealing material 130 having water swelling performance. Compared with Embodiment 10, the arrangement of the sealing material 120 and the sealing material 130 having water swelling performance is different. In Fig. 12, the watertight maintenance means 3 is illustrated.

[0074] As shown in Fig. 12(a), when the water stop device 1 is inserted into the inner opening 11 of the door frame 10 from the front side (outdoor side), the sealing material 120 is attached to the mounting surface of the water stop wall 2 so that there is no gap on the front side between the surfaces (left surface 12, right surface 13, bottom surface 14) of the inner opening 11 and the left end surface 22, right end surface 23, and bottom end surface 24 which are the mounting surfaces of the water stop wall 2. However, a gap is formed on the rear side between the surface of the inner opening 11 and the mounting surface of the water stop wall 2. After the water stop device 1 is inserted into the inner opening 11 of the door frame 10 from the front side (outdoor side), as shown in Fig. 12(b), the gap between the surface of the inner opening 11 formed behind the sealing material 120 and the mounting surface of the water stop wall 2 is filled with the sealing material 130 having water swelling performance from the rear side (indoor side), so that the watertightness between the mounting surface of the water stop wall 2 and the surface of the inner opening 11 of the door frame 10 is maintained. That is, in the water stop device 1 according to Embodiment 11, when the water stop wall 2 is inserted into the inner opening 11 of the door frame 10 from the front side (outdoor side), the sealing material 120 is attached to the mounting surface of the water stop wall 2 so as to be positioned biased to the front side, which is the side opposite to the insertion direction of the water stop device 1, between the mounting surface of the water stop wall 2 and the surface of the inner opening 11. Then, the gap between the mounting surface of the water stop wall 2 inserted into the inner opening 11 of the door frame 10 and the surface of the inner opening 11 is filled with the sealing material 130 having water swelling performance from the rear side (indoor side), so that the watertightness between the mounting surface of the water stop wall 2 and the surface of the inner opening 11 is maintained.

[0075] Based on Fig. 12, the watertight treatment by the watertight maintenance means 3 in the water stop device 1 according to Embodiment 11 will be described. First, as shown in Fig. 12(a), the water stop device 1 is inserted into the inner opening 11 of the door frame 10 from the front side (outdoor side). At this time, a sealing material 120 is arranged on the front side between the left surface 12 of the inner opening 11 and the left end surface 22 of the water stop wall 2 so as to maintain watertightness between the left surface 12 of the inner opening 11 and the left end surface 22 of the water stop wall 2. Thereafter, from the rear side (indoor side), as shown in Fig. 12(b), a sealing material 130 having water swelling performance is filled into the gap between the left surface 12 of the inner opening 11 and the left end surface 22 of the water stop wall 2 formed behind the sealing material 120. As a result, watertight performance by the sealing material 120 and the sealing material 130 having water swelling performance is exhibited before and after between the left surface 12 of the inner opening 11 and the left end surface 22 of the water stop wall 2, and watertightness between the left surface 12 of the inner opening 11 and the left end surface 22 of the water stop wall 2 is maintained well. In addition, the watertightness maintaining means 4 and 5 are also configured in the same manner as the above-described watertightness maintaining means 3, and it goes without saying that the same operational effects can be obtained.

[0076] According to the water stop device 1 according to Embodiment 11, the water stop device 1 is inserted into the inner opening 11 of the door frame 10 from the front side (outdoor side), and a sealing material 120 is arranged on the front side between the surface of the inner opening 11 and the surface of the water stop wall 2 so as to maintain watertightness between the surface of the inner opening 11 and the surface of the water stop wall 2. After that, a sealing material 130 having water swelling performance is filled from the rear side (indoor side) into the gap between the surface of the inner opening 11 and the surface of the water stop wall 2 formed behind the sealing material 120. By such a simple mounting operation, a water stop device 1 excellent in watertightness maintaining function and supporting function can be obtained.

[0077] Embodiment 12 In the water stop device 1 according to Embodiment 3 described above, as shown in Fig. 4, the sealing materials constituting the watertightness maintaining means 3, 4, and 5 are formed such that the thickness dimension from the mounted surface of the water stop wall 2 to which the sealing material is attached gradually increases from the tip side to the end side when the water stop wall 2 is inserted into the inner opening 11 from the front side (outdoor side). As an example of the configuration, the surfaces of the sealing material that come into contact with the left surface 12, right surface 13, and lower surface 14 of the inner opening 11 of the door frame 10 are formed as inclined surfaces. On the other hand, in the water stop device 1 according to Embodiment 12, as shown in FIG. 13, the left end face 22, the right end face 23, and the lower end face 24 of the water stop wall 2 are formed as inclined surfaces that gradually approach the left face 12, the right face 13, and the lower face 14 of the inner opening 11 of the door frame 10 from the tip side to the end side when the water stop wall 2 is inserted into the inner opening 11 from the front side (outdoor side). Furthermore, after inserting the water stop wall 2 into the inner opening 11 from the front side (outdoor side), a sealing material 130 having water swelling performance or a sealing material 120 is filled into the gap between the inclined surface of the water stop wall 2 and the left face 12, the right face 13, and the lower face 14 of the inner opening 11 of the door frame 10 from the rear side (indoor side). By doing so, the water stop device 1 is configured to maintain watertightness between the inclined surface (left end face 22, right end face 23, lower end face 24) of the water stop wall 2 and the surfaces (left face 12, right face 13, lower face 14) of the inner opening 11 of the door frame 10. In FIG. 13, the watertightness maintaining means 3 is illustrated.

[0078] Based on FIG. 13, the watertightness treatment by the watertightness maintaining means 3 in the water stop device 1 according to Embodiment 12 will be described. First, as shown in FIG. 13(a), the water stop device 1 is inserted into the inner opening 11 of the door frame 10 from the front side (outdoor side). At this time, a gap having a triangular cross-section or a trapezoidal cross-section is formed between the left face 12 of the inner opening 11 and the left end face 22 formed on the inclined surface of the water stop wall 2. The gap is a gap whose cross-sectional width becomes narrower as it approaches the front side. After that, as shown in FIG. 13(b), from the rear side (indoor side), a sealing material 130 having water swelling performance or a sealing material 120 is filled into the gap between the left face 12 of the inner opening 11 and the left end face 22 formed on the inclined surface of the water stop wall 2. As a result, the watertightness between the left face 12 of the inner opening 11 and the left end face 22 which is the inclined surface of the water stop wall 2 is maintained well. In this case, the sealing material 130 etc. filled into the gap from the rear side (indoor side) is crushed by the surface forming the narrow part on the front side of the gap and firmly filled into the narrow space. Therefore, the watertight performance between the left face 12 of the inner opening 11 and the left end face 22 of the water stop wall 2 is further improved. It goes without saying that the watertightness maintaining means 4 and 5 are also configured in the same manner as the above-described watertightness maintaining means 3, and the same operational effects can be obtained.

[0079] According to the water stop device 1 according to Embodiment 12, after inserting the water stop device 1 into the inner opening 11 of the door frame 10 from the front side (outdoor side), a simple mounting operation of filling a narrow gap on the front end side formed between the surface of the inner opening 11 and the inclined surface of the water stop wall 2 with a sealing material 130 having water swelling performance or the like from the rear side (indoor side) enables the water stop device 1 excellent in water tightness maintenance function and support function to be obtained.

[0080] Embodiment 13 The water stop device 1 according to Embodiment 13 has, instead of the watertightness maintaining means 3, 4, 5 having a configuration in which the leaf spring 100 and the sealing material 110 described in Embodiment 9 (FIG. 10) are combined, a mounting portion attached to the left end surface 22, the right end surface 23, and the lower end surface 24 of the water stop wall 2 which is the surface to be attached of the water stop wall 2, and an elastic portion provided so as to extend from the mounting portion, and is configured to include a long elastic sealing material having, for example, a V-shaped cross section or a U-shaped cross section. In addition, when a force is applied to one plate portion and the other plate portion of the V shape or U shape of the elastic sealing material, the elastic sealing material is configured such that, due to the elasticity of the bent portion which is the boundary portion between one plate portion and the other plate portion of the V shape or U shape, one plate portion and the other plate portion of the V shape or U shape are biased in a direction in which they separate from each other. Further, similar to the leaf spring 100 described in Embodiment 9 (FIG. 10), the elastic sealing material is configured such that the bent portion which is the boundary portion between the mounting portion and the elastic portion is located on the tip side when the water stop wall 2 is inserted into the inner opening 11 of the door frame 10, and the outer surface of the mounting portion of the elastic sealing material and the left end surface 22, the right end surface 23, and the lower end surface 24 which are the surfaces to be attached of the water stop wall 2 are adhered with an adhesive or the like. The elastic sealing material may be, for example, a single material structure formed only of rubber or other sealing materials, or a composite material structure composed of a core material formed of a material other than the sealing material and a sealing material provided so as to cover the periphery of the core material. For the elastic sealing material having the composite material structure, for example, those manufactured by two-color molding or other manufacturing methods may be used. For example, as the elastic sealing material having the composite material structure, an elastic sealing material having a structure in which a leaf spring formed of metal, synthetic resin, or the like is used as the core material and the periphery of the leaf spring is covered with a sealing material may be used.

[0081] According to the water stop device 1 according to Embodiment 13, similar to Embodiment 9 (FIG. 10), by a simple mounting operation of inserting the water stop device 1 into the inner opening 11 of the door frame 10 from the front side (outdoor side), a water stop device 1 excellent in the water tightness maintaining function and the supporting function can be obtained.

[0082] Embodiment 14 As shown in FIG. 14, the water stop device 1 according to Embodiment 14 is such that, as described in Embodiment 3 (FIGS. 4(a) and (b)), the sealing materials constituting the water tightness maintaining means 3, 4, 5 are from the tip side to the end side when the water stop wall 2 is inserted into the inner opening (opening) 11 from the front side (outdoor side). The inclined surfaces formed as surfaces that come into contact with the left end surface 22, the right end surface 23, and the lower end surface 24 of the surface to be attached, on which the sealing materials constituting the water tightness maintaining means 3, 4, 5 are attached, are formed so that the thickness dimensions gradually increase. The structure is provided with projecting pieces.

[0083] FIG. 14(a) shows the water tightness maintaining means 5 provided with a plurality of projecting pieces 5d on the inclined surface 5a formed as a surface that comes into contact with the lower surface 14 of the inner opening 11 of the door frame 10 so that the thickness dimension from the lower end surface 24 of the water stop wall 2, which is the surface to be attached, gradually increases from the tip side to the end side as described above. FIG. 14(b) shows the left water tightness maintaining means 3 provided with a plurality of projecting pieces 3d on the inclined surface 3a formed as a surface that comes into contact with the left surface 12 of the inner opening 11 of the door frame 10 so that the thickness dimension from the left end surface 22 of the water stop wall 2, which is the surface to be attached, gradually increases from the tip side to the end side as described above. Although not shown, similarly, the right water tightness maintaining means 4 has a plurality of projecting pieces formed on the inclined surface as the surface that comes into contact with the right surface 13 of the inner opening 11 of the door frame 10 so that the thickness dimension from the right end surface 23 of the water stop wall 2, which is the surface to be attached, gradually increases from the tip side to the end side as described above.

[0084] As shown in FIGS. 14(a) and 14(b), a plurality of protruding pieces 3d and 5d are provided at intervals along the front-rear direction (tip-end direction) on each of the inclined surfaces 3a and 5a, and are formed so as to extend in the normal direction of each of the inclined surfaces 3a and 5a. The plurality of protruding pieces 3d and 5d provided on each of the inclined surfaces 3a and 5a are formed in a linear shape with, for example, the same protruding amount in a cross-sectional view. Note that the shape and protruding amount of the protruding piece in a cross-sectional view may be, for example, a cross-sectional sickle shape protruding obliquely rearward (end side) from the inclined surface as shown in FIGS. 4(c) and 4(d) of Embodiment 3, and the protruding piece provided on the rear side (end side) may be formed so that the protruding amount and size are larger. The shape and protruding amount may be changed as appropriate.

[0085] According to the water stop device 1 according to Embodiment 14, when the water stop device 1 is inserted into the inner opening 11 of the door frame 10 from the front side (outdoor side), even if the design parallelism of the left end surface 22, the right end surface 23, and the lower end surface 24 of the water stop wall 2 facing the left surface 12, the right surface 13, and the lower surface 14 of the door frame 10 is not maintained, the protruding pieces provided on the watertight maintenance means 3, 4, and 5 can absorb the dimensional changes in the gaps between the left surface 12 and the left end surface 22, between the right surface 13 and the right end surface 23, and between the lower surface 14 and the lower end surface 24. Thus, a water stop device 1 with excellent watertight maintenance function and support function can be obtained while facilitating the insertion of the water stop device 1 into the inner opening 11 of the door frame 10 from the front side (outdoor side). The case where the design parallelism is not maintained means that, for example, when the door frame 10 and the water stop wall 2 manufactured within the range of machining tolerances are combined, narrow or wide portions of the gap occur in the extending direction of the gap between the left surface 12 and the left end surface 22.

[0086] In Embodiment 14, although the protruding pieces are described as being formed in Embodiment 3 (FIGS. 4(a) and 4(b)), the same effects as those of Embodiment 14 can also be obtained by providing them on the surfaces of the watertight maintenance means 3, 4, and 5 that face and contact the left surface 12, the right surface 13, and the lower surface 14 of the door frame 10 in each of the foregoing embodiments except Embodiment 3 (FIGS. 4(c) and 4(d)).

[0087] Embodiment 15 In the water stop device 1 according to Embodiments 1 to 3 and the like, an example is shown in which the sealing materials constituting the watertight maintenance means 3, 4, and 5 are attached to the left end face 22, the right end face 23, and the lower end face 24 of the water stop wall 2. However, in the water stop device 1 according to Embodiment 15, as shown in FIG. 15, the watertight maintenance means 3, 4, and 5 are configured such that, in addition to the left end face 22, the right end face 23, and the lower end face 24 of the water stop wall 2 which are the surfaces to be attached, a sealing material is formed so as to wrap around the indoor wall surface 21b of the wall plate portion 2a. As shown in FIG. 15, the sealing material according to Embodiment 15 will be described using Embodiment 3 (FIGS. 4(a) and (b)). The portions attached to the left end face 22, the right end face 23, and the lower end face 24 of the water stop wall 2 are formed such that the thickness dimension from the surface to be attached of the water stop wall 2 gradually increases from the tip side to the end side when the water stop wall 2 is inserted into the inner opening (opening) 11 from the front side (outdoor side). Continuously with this tip side, it is formed to include a flat extension piece that extends along the indoor wall surface 21b of the wall plate portion 2a. That is, the sealing material is configured in a substantially L shape in a cross-sectional view as shown in FIG. 14.

[0088] FIG. 15(a) shows the watertight maintenance means 5 formed such that the extension piece 5Z extending from the lower end face 24 of the water stop wall 2 which is the surface to be attached to the indoor wall surface 21b is attached to the wall surface 21b from the tip side to the end side as described above. FIG. 15(b) shows the left watertight maintenance means 3 formed such that the extension piece 3Z extending from the left end face 22 of the water stop wall 2 which is the surface to be attached to the indoor wall surface 21b is attached to the wall surface 21b from the tip side to the end side as described above. Although not shown, similarly, the right watertight maintenance means 4 is formed such that the extension piece extending from the right end face 23 of the water stop wall 2 which is the surface to be attached to the indoor wall surface 21b is attached to the wall surface 21b from the tip side to the end side as described above.

[0089] According to the water stop device 1 according to Embodiment 15, when the extension piece is attached to the wall surface 21b and the water stop device 1 is inserted into the inner opening 11 of the door frame 10 from the front side (outdoor side), peeling of the watertight maintenance means 3, 4, and 5 can be prevented by friction with the left surface 12, the right surface 13, and the lower surface 14 of the door frame 10. That is, as described in Embodiments 1 to 3, when the watertight maintenance means 3, 4, and 5 are attached only to the left end surface 22, the right end surface 23, and the lower end surface 24 of the watertight wall 2, the force due to friction with the door frame 10 acts parallel to the left end surface 22, the right end surface 23, and the lower end surface 24, and acts to peel the watertight maintenance means 3, 4, and 5 from the left end surface 22, the right end surface 23, and the lower end surface 24. However, since the extension piece is attached to the wall surface 21b, it is possible to resist this peeling force, and stable watertightness can be obtained in repeated use of the water stop device 1.

[0090] In addition, the technical ideas of Embodiments 1 to 15 in the water stop device 1 of the present invention are as follows. Embodiments 1 and 2 (Figs. 1 to 3) are technical ideas in which watertight maintenance means are provided on the surfaces (left end surface, right end surface, lower end surface) of the watertight wall to maintain the watertightness between the surface of the watertight wall and the surface of the opening (left surface, right surface, lower surface) and the support function of the opening that supports the watertight wall. Embodiment 3 (Fig. 4) is a technical idea in which the shape of the watertight maintenance means is devised so as to gradually become thicker from the tip to the end when the watertight wall is inserted into the opening, thereby maintaining the watertightness between the surface of the watertight wall and the surface of the opening and the support function of the opening that supports the watertight wall, and facilitating the attachment and detachment operation of the watertight wall with respect to the opening. Embodiment 4 (Fig. 5) is a configuration in which, after inserting the watertight wall into the opening using the watertight maintenance means provided with a groove, a pressing means is fitted into the groove of the watertight maintenance means to press the watertight maintenance means against the surface of the opening, thereby maintaining the watertightness between the surface of the watertight wall and the surface of the opening and the support function of the opening that supports the watertight wall, and facilitating the attachment and detachment operation of the watertight wall with respect to the opening. Embodiment 5 (Fig. 6) is a technical idea in which a support mechanism is provided on the watertight wall to improve the support function of the opening that supports the watertight wall. Embodiment 6 (Fig. 7) is a technical idea in which by providing a horizontal and vertical support mechanism for the water stop wall, the support function of the opening that supports the water stop wall is improved. As the watertight maintenance means that cannot be pressed against the surface of the opening among the left and right watertight maintenance means, a watertight maintenance means having a groove is used. After installing the water stop wall in the opening, a pressing means is inserted into the groove of the watertight maintenance means to press the watertight maintenance means against the surface of the opening, thereby improving the support function of the opening that supports the water stop wall and maintaining watertightness between the surface of the water stop wall and the surface of the opening. Embodiment 7 (Fig. 8) and Embodiment 8 (Fig. 9) are technical ideas in which the water stop wall is composed of a left water stop wall and a right water stop wall that are divided into left and right, so that each water stop wall can be made compact and is also easily applicable to an opening with a relatively large left and right opening width. Embodiment 9 (Fig. 10) is a technical idea in which the watertight maintenance means is configured as a combination of a leaf spring and a sealing material, so that the attachment operation of the water stop wall to the opening can be simplified, and the elastic force of the leaf spring is utilized to maintain watertightness between the surface of the water stop wall and the surface of the opening. Embodiment 10 (Fig. 11) and Embodiment 11 (Fig. 12) are configured using a sealing material and a sealing material having water swelling performance as the watertight maintenance means. The sealing material is attached to the surface (left end face, right end face, lower end face) of the water stop wall. After inserting the water stop wall into the opening, a sealing material having water swelling performance is filled between the sealing material and the surface (left face, right face, lower face) of the opening or between the surface of the water stop wall and the surface of the opening, thereby maintaining watertightness between the surface of the water stop wall and the surface of the opening. Embodiment 12 (Fig. 13) is a technical idea in which when the water stop wall is inserted into the opening, the surface (left end face, right end face, lower end face) of the water stop wall is formed into an inclined surface that gradually approaches the surface of the opening from the tip side to the end side when the water stop wall is inserted into the opening. After inserting the water stop wall into the opening, a sealing material is filled between the inclined surface of the water stop wall and the surface of the opening, thereby maintaining watertightness between the inclined surface of the water stop wall and the surface of the opening. Embodiment 13 uses, as the watertightness maintaining means, for example, a long elastic sealing material having a V-shaped or U-shaped cross section, and the bent portion, which is the boundary between the mounting portion and the elastic portion of the elastic sealing material, is positioned on the tip side when inserting the water stop wall into the opening. By adopting a configuration in which the elastic sealing material is attached to the surface (left end surface, right end surface, lower end surface) of the water stop wall, the attachment operation of the water stop wall to the opening can be simplified, and the elastic force of the elastic sealing material is utilized to maintain watertightness between the surface of the water stop wall and the surface of the opening. In addition, in Embodiment 13, for example, a form using an elastic sealing material having a single-material structure formed only of rubber or other sealing materials also corresponds to a configuration in which the shape of the watertightness maintaining means is gradually thickened from the tip to the end when inserting the water stop wall into the opening, as in Embodiment 3 (Fig. 4). Therefore, the form using the elastic sealing material having a single-material structure also has the technical idea of Embodiment 3. Embodiment 14 (Fig. 14) has a technical idea that by providing the watertightness maintaining means with a protruding piece, it is possible to absorb dimensional changes in the gaps between the left surface and the left end surface, the right surface and the right end surface, and the lower surface and the lower end surface, facilitating the insertion of the water stop device 1 from the front side (outdoor side) into the inner opening of the door frame and making the attachment and detachment operation of the water stop wall to the opening easier. Embodiment 15 (Fig. 15) has a technical idea that the watertightness maintaining means includes an extension piece, and by attaching the extension piece to the wall surface of the water stop wall, peeling of the watertightness maintaining means due to friction with the left surface, right surface, and lower surface of the door frame is prevented when inserting the water stop device into the door frame.

[0091] Also, the water stop device 1 of the present invention may be configured by appropriately combining two or more of the configurations of Embodiments 1 to 15. For example, if the water stop device 1 is a combination of the configurations of the watertightness maintaining means 3, 4, and 5 shown in Embodiment 4 (Fig. 5) and the configuration of the support mechanism 40 shown in Embodiment 5 (Fig. 6), a water stop device 1 with even better watertightness maintaining and support functions can be obtained. Also, the configurations of Embodiments 1 to 13 may be appropriately replaced. For example, the configuration of the watertightness maintaining means 3, 4, and 5 shown in Embodiment 4 (Fig. 5) may be changed to the configuration of the watertightness maintaining means shown in Embodiment 6 (Fig. 7(b)).

[0092] Furthermore, in Embodiments 1 to 6 and Embodiments 9 to 13, the water stop wall 2 formed in a box shape with a front opening and a rear closure, including a wall plate portion 2a, a left plate portion 2b, a right plate portion 2c, a lower plate portion 2d, an upper plate portion 2e, a left locking portion 6, a right locking portion 7, and a lower locking portion 8, was exemplified. However, the water stop wall may be a flat water stop wall that does not include the left locking portion 6, the right locking portion 7, and the lower locking portion 8. That is, the water stop device of the present invention may be a water stop device configured to include watertight performance maintaining members on the left end face, the right end face, and the lower end face of, for example, a flat water stop wall. Even with such a water stop device, it is possible to block an opening having a left face, a right face, and a lower face, such as an opening between left and right guide rails of a shutter device or an opening constituting an entrance / exit of a door, a wall, etc., and prevent water from passing through the opening. That is, even with such a water stop device, by installing the water stop device in the opening such that the left watertight maintaining means provided on the left end face of the water stop wall maintains watertightness between the left face of the opening, the right watertight maintaining means provided on the right end face of the water stop wall maintains watertightness between the right face of the opening, and the lower watertight maintaining means provided on the lower end face of the water stop wall maintains watertightness between the lower face of the opening, it is possible to block the opening and prevent water from passing through the opening.

[0093] Also, in each embodiment, an example was shown in which the watertight maintaining means was provided on the side of the surface (left end face, right end face, lower end face) of the water stop wall to maintain watertightness between the surface of the water stop wall (left end face, right end face, lower end face) and the surface (left face, right face, lower face) of an opening such as the inner opening of a door frame. However, the configuration may be such that the watertight maintaining means of each embodiment is provided on the side of the surface (left face, right face, lower face) of the opening, or the watertight maintaining means may be provided on both sides of the surface (left end face, right end face, lower end face) of the water stop wall and the surface (left face, right face, lower face) of the opening. That is, the water stop device according to the present invention includes at least a water stop wall, a left water tightness maintaining means provided on at least one of the left end surface of the water stop wall and the left surface of the opening to maintain the water tightness between the left end surface of the water stop wall and the left surface of the opening, a right water tightness maintaining means provided on at least one of the right end surface of the water stop wall and the right surface of the opening to maintain the water tightness between the right end surface of the water stop wall and the right surface of the opening, and a lower water tightness maintaining means provided on at least one of the lower end surface of the water stop wall and the lower surface of the opening to maintain the water tightness between the lower end surface of the water stop wall and the lower surface of the opening.

[0094] In the description of Embodiment 1, the water tightness maintaining means 3, 4, and 5 are configured as separate bodies, and the lower end surface of the left water tightness maintaining means 3 and the lower end surface of the right water tightness maintaining means 4 are in contact with the lower surface 14 of the inner opening 11 of the door frame 10 to maintain the water tightness performance therebetween. Also, the left end surface of the lower water tightness maintaining means 5 and the left water tightness maintaining means 3 are provided to be in close contact, and the right end surface of the lower water tightness maintaining means 5 and the right water tightness maintaining means 4 are provided to be in close contact. However, the lower water tightness maintaining means 5 may be configured to be in contact with the lower surface of the inner opening 11 of the door frame 10 to maintain the water tightness performance therebetween, the left end surface of the lower water tightness maintaining means 5 and the left water tightness maintaining means 3 may be provided to be in contact with the left surface 12 of the inner opening 11 of the door frame 10 to maintain the water tightness performance therebetween, and the right end surface of the lower water tightness maintaining means 5 and the right water tightness maintaining means 4 may be provided to be in contact with the right surface 13 of the inner opening 11 of the door frame 10 to maintain the water tightness performance therebetween.

[0095] Also, as shown in Embodiments 1, 3, etc., when the watertight maintenance means 3, 4, 5 are configured as separate bodies, the watertight maintenance means 3, 4, 5 are not limited to using a sealing material formed of the same material. For example, as shown in FIG. 1 etc., when the water stop device 1 in which the water stop wall 2 and the watertight maintenance means 3, 4, 5 are integrated is inserted into the inner opening 11 of the door frame 10, the insertion of the water stop device 1 into the inner opening 11 of the door frame 10 is assumed to be carried out by sliding the left and right watertight maintenance means 3; 4 into the inner opening 11 of the door frame 10 while pressing the watertight maintenance means 5 against the lower surface 14. At this time, the friction between the watertight maintenance means 3 and the left surface 12 and between the watertight maintenance means 4 and the right surface 13 becomes larger than the friction between the watertight maintenance means 5 and the lower surface 14. Also, the watertight maintenance means 3, 4, 5 configured separately or integrally may be provided on the door frame 10 side, or may be provided on both the door frame 10 side and the water stop wall 2 side.

[0096] In such a case, it is preferable to use a non-foamed rubber for the watertight maintenance means 3 and 4 and a foamed rubber for the watertight maintenance means 5. For example, when the watertight maintenance means 3, 4, 5 are formed using a foamed rubber as a material, the friction on the left surface 12 and the right surface 13 may increase, making it difficult to push in, and there is a risk that the watertight maintenance means 3, 4 may be damaged if forced to be pushed in. Therefore, by using a non-foamed rubber for the left and right watertight maintenance means 3, 4, it is possible to obtain ease of fitting and prevent damage.

[0097] Also, by using a foamed rubber for the watertight maintenance means 5, it follows the upward floating of the water stop wall 2 that easily occurs during pushing in, maintains the watertight state between the watertight maintenance means 5 and the lower surface 14, and makes it easier to obtain water stoppage performance when the water stop device 1 is attached and detached.

[0098] Hereinafter, based on FIGS. 16 to 30, the water stop device 1 according to Embodiments 16 to 24 will be described. In FIGS. 16, 17, 25, and 28, only the water stop wall 2 is illustrated in order to clarify the shape of the water stop wall 2 constituting the water stop device 1. That is, similar to the water stop wall 2 described in Embodiment 1 and the like, the water stop device 1 according to Embodiments 16 to 24 is configured to include the water stop wall 2 and the watertight maintenance means 3, 4, and 5 as shown in FIGS. 23, 24, 26, and 29. In addition, in FIGS. 16 to 30, the same parts or corresponding parts as those shown in FIGS. 1 to 15 of the above-described Embodiments 1 to 15 are denoted by the same reference numerals, and the description thereof is omitted. Also, the hatching in the cross-sectional views in FIGS. 16 to 30 is omitted.

[0099] Embodiment 16 In the water stop wall 2 described in each of the above-described Embodiments 1 to 15, the wall plate portion 2a is exemplified as having a configuration formed by a rectangular flat plate. However, the wall plate portion 2a may be configured by a wall plate portion 2a having a hollow structure formed by combining a plurality of shaped members 2m, 2m,... such as aluminum extrusion profiles as shown in FIG. 16(c), for example. For example, a water stop wall provided with a wall plate portion 2a configured by combining a plurality of shaped members 2m, 2m,... vertically is used. That is, as shown in FIGS. 16, 17, 18, 23, and 24, the water stop wall 2 includes a wall plate portion 2a having a hollow structure (plate-shaped hollow box body) configured by combining a plurality of shaped members 2m, 2m,... vertically, a left locking portion 6 provided so as to extend from the left end of the wall surface 21a located on the door 9 side in the wall plate portion 2a and locking to the door stop surface 16 on the left side of the inner opening 11 of the door frame 10, a right locking portion 7 provided so as to extend from the right end of the wall surface 21a and locking to the door stop surface 17 on the right side of the inner opening 11 of the door frame 10, and a lower locking portion 8 provided so as to extend from the lower end of the wall surface 21a and locking to the door stop surface 18 on the lower side of the inner opening 11 of the door frame 10. The water stop device 1 has such a configuration. In addition, in the water stop wall 2 of Embodiment 16, the upper plate (the upper plate of the shaped member 2m constituting the uppermost part of the wall plate portion 2a) of the wall plate portion 2a functions as the upper end portion of the water stop wall 2, and a handle 2H or the like is provided on the upper plate 2t as described later. In other words, in the water stop wall 2 of Embodiment 16, since the upper plate 2t of the wall plate portion 2a functions as the upper end portion of the water stop wall 2, the upper plate 2t corresponds to a portion equivalent to the upper plate portion 2e that functions as the upper end portion of the water stop wall 2 described in Embodiments 1 to 15.

[0100] As in the above-described Embodiments 1 to 15, when the wall plate portion 2a is configured by a flat plate, in order to increase the strength of the wall plate portion 2a, it is preferable to use a thick flat plate. However, when a thick flat plate is used, the weight of the water stop device 1 increases, and in operations such as installation work, removal work, and transportation work, the water stop device 1 may have poor workability (handlability). On the other hand, as in Embodiment 16, if the hollow wall plate portion 2a is configured by combining the profiles 2m, 2m..., the strength of the wall plate portion 2a is improved, and a water stop wall 2 provided with a lightweight wall plate portion 2a can be configured. That is, the strength of the wall plate portion 2a of the water stop wall 2 is improved, and a water stop device 1 with good handleability can be provided. For example, when configuring the water stop device 1 corresponding to the inner opening 11 of the double-opening door 9 as shown in FIG. 18, since the size of the wall plate portion 2a becomes large, if a thick flat plate is used as the wall plate portion 2a, the wall plate portion 2a becomes large and heavy, and the water stop device 1 may have poor workability (handlability). On the other hand, as in Embodiment 16, if a configuration is provided with a hollow wall plate portion 2a configured by combining a plurality of profiles 2m, 2m..., even when the size of the wall plate portion 2a becomes large, the strength of the wall plate portion 2a of the water stop wall 2 is improved, and the weight of the wall plate portion 2a of the water stop wall 2 can be reduced, so that a water stop device 1 with good workability (handlability) can be provided.

[0101] Embodiment 17 A handle 2H as shown in FIGS. 16 to 18 is provided at the upper end portion of the water stop wall 2, that is, at the upper plate (the upper plate of the profile 2m constituting the uppermost portion of the wall plate portion 2a) 2t of the wall plate portion 2a in the water stop wall 2 of Embodiment 16, or at the upper plate portion 2e of Embodiments 1 to 15. According to the water stop device 1 provided with such a handle 2H, when a person holds the handle 2H, operations such as the installation operation, removal operation, and transportation operation of the water stop device 1 can be easily performed. Therefore, a water stop device 1 with good workability (handlability) can be provided.

[0102] Embodiment 18 When the handle 2H is provided at the upper end of the water stop wall 2 in the water stop device 1, after the water stop device 1 is installed in a predetermined state in the inner opening 11 of the door frame 10, when closing the door 9 or when opening the door 9 from the closed state, there is a possibility that a protruding object protruding indoors from the inner surface of the door 9 may interfere with the handle 2H. In addition, the protruding object protruding indoors from the inner surface of the door 9 is a component that protrudes above the upper end of the water stop wall 2 from the inner surface of the closed door 9. For example, the handle 9N (lever handle) (see FIG. 18) of the door 9, movable components such as thumb turns and push-pull locks, or fixed components such as cylinders. Therefore, a water stop device 1 is provided with a handle 2H configured to avoid interference with a protruding object protruding indoors from the inner surface of the door 9. That is, as a handle 2H having a mechanism for avoiding interference with a protruding object protruding indoors from the inner surface of the closed door 9 at the upper end of the water stop wall 2, for example, a collapsible handle 2H as shown in FIG. 19(a), or a vertically movable handle 2H as shown in FIG. 19(b), or a rotatable handle 2H as shown in FIG. 19(c).

[0103] As the collapsible handle 2H, for example, a handle 2H having a configuration as shown in FIG. 20 is provided. The collapsible handle 2H is configured such that the handle 2H is attached to, for example, the upper plate 2t as the upper end of the water stop wall 2 via the attachment bases 2HB, 2HB. The handle 2H is formed in a U-shape, for example, and both ends 4a, 4a of the handle 2H are attached to the upper plate 2t of the water stop wall 2 via the attachment bases 2HB, 2HB so as to be able to be erected and folded. The mounting base 2HB is fixed to the upper plate 2t by mounting screws or the like (not shown). Both ends 4a, 4a of the handle 2 are rotatably attached to the mounting bases 2HB, 2HB via a rotation center shaft 4c that forms a rotation center 2R. The mounting bases 2HB, 2HB are configured to include a regulating surface 4b (see Fig. 20(a)) for maintaining the handle 2 in an upright state perpendicular to the upper plate 2t and a regulating surface 4f (see Fig. 20(b)) for maintaining the handle 2 in a fallen state on the rear side (indoors side). For example, the regulating surface 4b is constituted by a surface perpendicular to the flat upper surface of the upper plate 2t, and the regulating surface 4f is constituted by a surface parallel to the flat upper surface of the upper plate 2t. Therefore, when using the handle 2H, as shown in Fig. 20(a), set the handle 2H to the upright state for use. Also, when there is interference between the handle 2H and a protrusion protruding indoors from the inner surface of the door 9, as shown in Fig. 20(b), by setting the handle 2H to the fallen state, interference with the protrusion can be avoided.

[0104] As the vertically movable handle 2H, for example, a handle 2H as shown in Fig. 21 is provided. In the vertically movable handle 2H, through holes 2g, 2g for passing both ends 4a, 4a of the handle 2 through the upper plate 2t are formed, and on the tip side of both ends 4a, 4a of the handle 2, retaining means 4g are provided to prevent the end 4a of the handle 2 from coming out of the through hole 2g. Therefore, when using the handle 2H, as shown in Figs. 21(a) and (b), move the handle 2H upward until the retaining means 4g, 4g collide with the inner surface (lower surface) of the upper plate 2t for use. Also, when not using the handle 2H, as shown in Figs. 21(c) and (d), the handle 2H descends due to its own weight and is set to a state where interference with a protrusion protruding indoors from the inner surface of the door 9 can be avoided. Furthermore, if screw portions 4t are formed on the distal ends of both ends 4a, 4a of the handle 2, the retaining member 4g can be configured by a member such as a nut, and by adjusting the position of the retaining member 4g, the vertical movement range of the handle 2H can be adjusted.

[0105] As the rotary handle 2H, for example, a handle 2H as shown in FIG. 22 is provided. In the rotary handle 2H, one end 4a of both ends 4a, 4a of the handle 2 is rotatably attached to the upper plate 2t, and an end entrance / exit groove 2h is formed in the wall plate portion 2a so that the other end 4a can enter and exit. The end entrance / exit groove 2h is formed so as to straddle the upper plate 2t of the wall plate portion 2a and the wall surface (the wall surface facing the indoor side) 21b. On the distal end side of one end 4a, there are provided an upper nut 4i screwed to the screw portion 4t formed on the distal end side of one end 4a and positioned above the upper plate 2t, a washer 4j inserted into the screw portion 4t and positioned below the upper plate 2t, and a lower nut 4k inserted into the screw portion 4t and positioned below the washer 4j. By loosening the fastening of the upper nut 4i to the upper plate 2t, the handle 2H is set in a rotatable state with the central axis of one end 4a as the rotation center 2R. Also, by fastening the upper nut 4i to the upper plate 2t, the handle 2H is set in a non-rotatable state with the central axis of one end 4a as the rotation center 2R. Therefore, when using the handle 2H, as shown in FIG. 22(a), with the other end 4a positioned in the end entrance / exit groove 2h, the upper nut 4i is fastened to set the handle 2H in a non-rotatable state before use. And when there is interference between a protruding object protruding indoors from the inner surface of the door 9 and the handle 2H, the fastening of the upper nut 4i is loosened, and the handle 2H is rotated with the central axis of one end 4a as the rotation center 2R, and the other end 4a is moved from inside the end entrance / exit groove 2h to the indoor side (rear side) to set a state where interference with the protruding object can be avoided.

[0106] As described above, if the water stop device 1 is provided with a collapsible, vertically movable, or rotatable handle 2H as in Embodiment 18, for example, when the water stop device 1 is installed so as to close the inner opening 11 of the door frame 10 and the door 9 is closed, it is possible to prevent interference between a protrusion protruding inward of the room from the inner surface of the door 9 and the handle 2H. Therefore, for example, it becomes possible to set the height dimension of the water stop device 1 to the height dimension up to the position directly below the door handle (lever handle) 9N provided on the inner surface of the door 9, and it becomes possible to provide a water stop device 1 that can prevent interference between the door handle 9N and the handle 2H when the door handle 9N is operated. For example, in FIG. 18, it is possible to further increase the height dimension of the water stop device 1 up to the position directly below the door handle 9N. Note that the handle 2H may have a configuration other than the collapsible, vertically movable, or rotatable configurations described above, as long as it can prevent interference with a protrusion protruding inward of the room from the inner surface of the closed door 9. For example, the handle 2H may be configured to be attached to the upper plate 2t so as to be movable in the left-right direction of the upper plate 2t, or the handle 2H may be configured to be detachable from the upper plate 2t.

[0107] Embodiment 19 A configuration is adopted in which a hook portion 2F as shown in FIGS. 16 to 18 is provided at the upper end portion of the water stop wall 2, for example, at the upper plate 2t of the wall plate portion 2a of the water stop wall 2 described above, or at the upper plate portion 2e of Embodiments 1 to 15. According to the water stop device 1 provided with the hook portion 2F in this way, for example, it is possible to hang the water stop device 1 on the wall surface by hanging the hook portion 2F on a wall-mounted hook or the like provided on the wall surface and store it in a suspended state, so that floor storage can be avoided, and it is not necessary to provide a dedicated floor space for storage.

[0108] An example of the water stop device 1 installed in the inner opening 11 having the configurations of Embodiments 16 to 19 is shown in FIG. 18. The water stop device 1 is configured such that the wall plate portion 2a of the water stop wall 2 is formed by a plate-shaped hollow box body formed by combining a plurality of profiles 2m, 2m such as aluminum extrusion profiles, and a handle 2H and a hook portion 2F are attached to the upper end portion of the wall plate portion 2a. The handle 2H and the hook portion 2F are preferably provided one on each of the left and right sides of the upper plate 2t of the wall plate portion 2a.

[0109] Embodiment 20 The water stop device 1 is attached in a state of being fixed to the left surface 12, right surface 13, lower surface 14, and upper surface 15 of the inner opening 11 of the door frame 10, and in a state where the door 9 is closed, the wall surface (the wall surface facing the outdoor side) 21a of the wall plate portion 2a of the water stop wall 2 and the protrusion protruding from the indoor side surface of the door 9 do not interfere with each other. In addition, in a state where the water stop device 1 is installed in the inner opening 11 of the door frame 10 and the door 9 is closed, the protrusions that may protrude from the indoor side surface of the door 9 and contact the wall surface 21a of the wall plate portion 2a of the water stop wall 2 include, for example, the mating portion between one door 9L and the other door 9R of the double-opening door 9, the handle 9N (lever handle) of the door 9, the cylinder, the thumb turn, the push-pull lock, etc.

[0110] That is, the water stop wall 2 includes the wall plate portion 2a, the left locking portion 6, the right locking portion 7, and the lower locking portion 8 described above. The length from the left end of the wall surface 21a of the wall plate portion 2a to the left locking portion 6, the length from the right end of the wall surface 21a to the right locking portion 7, and the length from the lower end of the wall surface 21a to the lower locking portion 8 are formed to be the same length, and the length from each end surface of the wall surface 21a to each locking portion is longer than the protruding length of the protrusion protruding from the indoor side surface of the closed door 9. The water stop device 1 has such a configuration. In other words, as shown in FIGS. 23 and 24, a left plate portion 2b provided so as to extend from the left end edge of the wall surface 21a of the wall plate portion 2a to the left locking portion 6 on the front side, a right plate portion 2c provided so as to extend from the right end edge of the wall surface 21a of the wall plate portion 2a to the right locking portion 7 on the front side, and a lower plate portion 2d provided so as to extend from the lower end edge of the wall surface 21a of the wall plate portion 2a to the lower locking portion 8 on the front side are set to appropriate lengths, whereby the wall surface 21a of the wall plate portion 2a of the water stop device 1 installed so as to close the inner opening 11 of the door frame 10 is configured not to contact a protrusion protruding from the indoor side surface of the closed door 9. The water stop device 1 is provided with a water stop wall 2 having such a configuration.

[0111] According to Embodiment 20, the lengths of the left plate portion 2b, the right plate portion 2c, and the lower plate portion 2d in the front-rear direction are increased, and the dimensions from the wall surface 21a facing the outdoor side (front side) of the wall plate portion 2a to the left locking portion 6, the right locking portion 7, and the lower locking portion 8 (in other words, the depth dimension of the recess surrounded by the wall surface 21a serving as the bottom surface of the recess, the left plate portion 2b, the right plate portion 2c, and the lower plate portion 2d) are made sufficiently longer than the protruding length of the protrusion protruding from the indoor side surface of the closed door 9. Thus, the water stop device 1 has a water stop wall 2. Therefore, when the water stop device 1 is attached to the inner opening 11 of the door frame 10 and the door 9 is in a closed state, interference between the wall surface 21a of the wall plate portion 2a of the water stop wall 2 and the protrusion protruding from the indoor side surface of the door 9 can be avoided.

[0112] Embodiment 21 As described in Embodiment 20, when the width dimension of the water stop wall 2 in the front-rear direction is increased, the width dimensions (hereinafter referred to as width dimension A) of the left end surface 22, the right end surface 23, and the lower end surface 24 of the water stop wall 2 in the front-rear direction become longer. In this way, when the width dimension A of the water stop wall 2 is increased, the length of the width dimension A of the water stop wall 2 may become longer than the length of the width dimensions (hereinafter referred to as width dimension B) of the left surface 12, the right surface 13, and the lower surface 14 of the door frame 10 in the front-rear direction. That is, in FIGS. 23 and 24, the case where the length of the width dimension A described above is shorter than the length of the width dimension B is illustrated, but the length of the width dimension A may be longer than the length of the width dimension B. As a water stop device 1 to be installed in the inner opening 11 of the door frame 10 formed with a width dimension B shorter than such a width dimension A, when the water stop device 1 is installed in the inner opening 11 of the door frame 10, it is necessary to have watertight maintenance means 3, 4, and 5 on the surfaces of the left end face 22, right end face 23, and lower end face 24 of the water stop wall 2 facing the left face 12, right face 13, and lower face 14 of the door frame 10.

[0113] Therefore, in Embodiment 21, even when the length of the width dimension A is longer than the length of the width dimension B in this way, in order to be able to cope with it and maintain the watertight performance between the left end face 22, right end face 23, lower end face 24 of the water stop wall 2 of the water stop device 1 and the left face 12, right face 13, lower face 14 of the inner opening 11 of the door frame 10, the water stop device 1 is as follows. That is, the watertight maintenance means 3, 4, and 5 are extended to the vicinity positions of the left locking portion 6, right locking portion 7, and lower locking portion 8 at the left end face 22, right end face 23, and lower end face 24 of the water stop wall 2, and the water stop device 1 is configured. Alternatively, the watertight maintenance means 3, 4, and 5 are provided only at the vicinity positions of the left locking portion 6, right locking portion 7, and lower locking portion 8 at the left end face 22, right end face 23, and lower end face 24 of the water stop wall 2 facing the left face 12, right face 13, and lower face 14 of the inner opening 11 of such a door frame 10, and the water stop device 1 is configured. That is, the water stop wall 2 includes a wall plate portion 2a, a left locking portion 6, a right locking portion 7, and a lower locking portion 8, and at least in the vicinity position of the left locking portion 6 at the left end face 22 of the water stop wall 2 facing the left face 12 of the inner opening 11 of the door frame 10, and at least in the vicinity position of the right locking portion 7 at the right end face 23 of the water stop wall 2 facing the right face 13 of the inner opening 11 of the door frame 10, and at least in the vicinity position of the lower locking portion 8 at the lower end face 24 of the water stop wall 2 facing the lower face 14 of the inner opening 11 of the door frame 10, the watertight maintenance means 3, 4, and 5 are respectively provided, and the water stop device 1 is configured.

[0114] Also, in this case, in order to further improve the watertight performance, as the watertight maintenance means 3, 4, 5 provided in the vicinity of the left locking portion 6, the right locking portion 7, and the lower locking portion 8 on the left end surface 22, the right end surface 23, and the lower end surface 24 of the watertight wall 2, for example, as shown in FIGS. 4(a), 4(b), and 15, the watertight maintenance means having inclined surfaces 3a, 4a, 5a as the watertight performance improvement means can be used, or as shown in FIGS. 4(c), 4(d), 14, and 24, the watertight maintenance means having protruding pieces 3a, 4a, 5a as the watertight performance improvement means is preferably used.

[0115] As described above, according to the 21st embodiment, even when the length of the width dimension A is longer than the length of the width dimension B, it is possible to provide the waterstop device 1 that can cope with this situation and can maintain the watertight performance between the left end surface 22, the right end surface 23, and the lower end surface 24 of the watertight wall 2 and the left surface 12, the right surface 13, and the lower surface 14 of the door frame 10 by the watertight maintenance means 3, 4, 5.

[0116] 22nd Embodiment For example, as shown in FIGS. 23 and 24, in the door frame 10, in the peripheral groove 10a formed around the frame on the opening and closing side of the door 9 (that is, the front side of the door frame 10), usually, the door 9 and the door frame 10 are not directly contacted, and in order to ensure the adhesion between the periphery of the inner surface of the door 9 and the door frame 10, a cushion material 10b called "airtight rubber" or the like is provided. Therefore, when the front ends 3e, 4e, 5e of the watertight maintenance means 3, 4, 5 are brought into contact with the left locking portion 6, the right locking portion 7, and the lower locking portion 8, or when an appropriate space is not provided between the front ends 3e, 4e, 5e of the watertight maintenance means 3, 4, 5 and the left locking portion 6, the right locking portion 7, and the lower locking portion 8, when the door 9 is closed, the cushion material 10b may be crushed, and a part of the cushion material 10b may cross the door contact surfaces 16, 17, 18 and come into contact with the front ends 3e, 4e, 5e of the watertight maintenance means 3, 4, 5. Thus, when a part of the cushion material 10b comes into contact with the watertight maintenance means 3, 4, 5, a gap serving as a water channel is formed between the part of the contacted cushion material 10b and the watertight maintenance means 3, 4, 5, and the watertight performance by the watertight maintenance means 3, 4, 5 may be impaired. Therefore, as shown in FIGS. 23 and 24, an appropriate gap, that is, a clearance gap 3s, 4s, 5s for preventing interference is provided between the front ends 3e, 4e, 5e of the watertight maintenance means 3, 4, 5 and the left locking portion 6, the right locking portion 7, and the lower locking portion 8. That is, a clearance gap 3s, 4s, 5s for preventing interference between the watertight maintenance means 3, 4, 5 and the cushion material 10b is provided between the front ends 3e, 4e, 5e, which are one ends on the side of the left locking portion 6, the right locking portion 7, and the lower locking portion 8 in the watertight maintenance means 3, 4, 5, and the left locking portion 6, the right locking portion 7, and the lower locking portion 8. That is, when the door frame 10 is provided with a cushion material 10b for preventing the door 9 and the door frame 10 from coming into direct contact with each other in the peripheral groove 10a formed around the frame on the opening and closing side of the door 9 and for ensuring the adhesion between the periphery of the inner surface of the door 9 and the door frame 10, a clearance gap 3s, 4s, 5s for preventing interference between a part of the cushion material 10b deformed when the door 9 is closed and the watertight maintenance means 3, 4, 5 is provided between the watertight maintenance means 3, 4, 5 provided near the positions of the respective locking portions 6, 7, 8 and the respective locking portions 6, 7, 8. The water stop device 1 has such a configuration. According to the water stop device 1 according to Embodiment 22, interference between the cushion material 10b of the door frame 10 and the watertight maintenance means 3, 4, 5 of the water stop device 1 when the door 9 is closed can be prevented, and a situation in which the watertight performance is impaired can be avoided.

[0117] Embodiment 23 Due to manufacturing errors, that is, tolerances, of the door frame 10 and the water stop device 1, a gap may occur between the left watertight maintenance means 3 and the left surface 12 of the door frame 10 or between the right watertight maintenance means 4 and the right surface 13 of the door frame 10, and the watertight performance between the left watertight maintenance means 3 and the left surface 12 of the door frame 10 or between the right watertight maintenance means 4 and the right surface 13 of the door frame 10 may not be sufficiently maintained. In addition, there is a possibility that the water stop device 1 cannot be surely installed in the inner opening 11 so as to be sandwiched and fixed between the left surface 12 and the right surface 13 of the door frame 10. Therefore, as shown in FIGS. 25, 26, and 27, a water stop device 1 is configured with pressing mechanisms 6A, 6A to press the left plate portion 2b toward the left surface 12 of the inner opening 11 of the door frame 10, or to press the right plate portion 2c toward the right surface 13 of the inner opening 11 of the door frame 10. That is, in the water stop device 1 configured such that the water stop wall 2 includes a wall plate portion 2a, a left locking portion 6, a right locking portion 7, and a lower locking portion 8, and a left water tightness maintaining member 3 is provided on the left end surface 22, which is a plate surface facing the left surface 12 of the inner opening 11 of the door frame 10, on the left plate portion 2b from the left end of the wall surface 21a of the wall plate portion 2a to the left locking portion 6, and a right water tightness maintaining member 4 is provided on the right end surface 23, which is a plate surface facing the right surface 13 of the inner opening 11 of the door frame 10, on the right plate portion 2c from the right end of the wall surface 21a of the wall plate portion 2a to the right locking portion 7, and a lower water tightness maintaining member 5 is provided on the lower end surface 24, which is a plate surface facing the lower surface 14 of the inner opening 11 of the door frame 10, on the lower plate portion 2d from the lower end of the wall surface 21a of the wall plate portion 2a to the lower locking portion 8, the water stop device 1 is configured to include a pressing mechanism 6A for pressing the left plate portion 2c toward the left surface 12 of the door frame 10 and a pressing mechanism 6A for pressing the right plate portion 2c toward the right surface 13 of the door frame 10 on the wall surface 21a located on the door side of the water stop wall 2.

[0118] As shown in FIGS. 26 and 27, the pressing mechanism 6A for pressing the right plate portion 2c toward the right surface 13 of the door frame 10 includes a mounting base 6a and a pressing member. The mounting base 6a is formed of, for example, an L-shaped angle bracket, and the other flat plate of the L-shape is fixed to the wall surface 21a with a fixing member 6b such as a screw so that the plate surface of one flat plate of the L-shape and the plate surface of the right plate portion 2c face each other in parallel. The pressing member includes a bolt through-hole (not shown) formed to penetrate one flat plate of the L-shaped angle bracket, a bolt 6c, and a nut 6d. The nut 6d is fixed to the plate surface of the one flat plate by fixing means such as welding so that the screw hole of the nut 6d is continuous with the bolt through-hole formed in the plate surface of the one flat plate of the L-shaped angle bracket facing the left surface 12 in parallel. Then, bolt 6c passes through a bolt through-hole (not shown) and the threaded hole of nut 6d, and a pressing end 6e formed by the tip of bolt 6c is configured to be able to advance and retract in a direction approaching right plate portion 2c and a direction away from right plate portion 2c. In addition, for pressing mechanism 6A for pressing left plate portion 2c toward the left surface 12 of door frame 10, the flat plate surface of one of the L-shaped flat plates of the L-shaped angle bracket constituting mounting base 6a and the flat plate surface of left plate portion 2b face each other in parallel, and the other L-shaped flat plate is fixed to wall surface 21a with fixing members 6b such as screws. Then, bolt 6c passes through a bolt through-hole (not shown) and the threaded hole of nut 6d, and a pressing end 6e formed by the tip of bolt 6c is configured to be able to advance and retract in a direction approaching left plate portion 2b and a direction away from left plate portion 2b. Also, as shown in FIG. 25, it is preferable to provide a plurality of pressing mechanisms 6A at predetermined intervals along the vertical direction of left plate portion 2b and right plate portion 2c. With such a configuration, it is possible to press the entire left plate portion 2b and the entire right plate portion 2c almost evenly using a plurality of pressing mechanisms 6A, 6A..., which is preferable.

[0119] According to the waterstop device 1 according to Embodiment 23, even when a gap is generated between the left watertight maintenance means 3 and the left surface 12 of the door frame 10 or between the right watertight maintenance means 4 and the right surface 12 of the door frame 10 due to the tolerances of the door frame 10 and the waterstop wall 1, by pressing the left plate portion 2b toward the left surface 12 of the door frame 10 or pressing the right plate portion 2c toward the left surface 12 of the door frame 10 with the pressing mechanism 6A, the adhesion between the left watertight maintenance means 3 and the left surface 12 of the door frame 10 or the adhesion between the right watertight maintenance means 4 and the right surface 13 of the door frame 10 can be improved. Therefore, it is possible to cope with the tolerances of the door frame 10 and the waterstop wall 1, sufficiently maintain the watertight performance between the left watertight maintenance means 3 and the left surface 12 of the door frame 10 and the watertight performance between the right watertight maintenance means 4 and the right surface 13 of the door frame 10, and provide a waterstop device 1 that can be surely installed in the inner opening 11 so as to be sandwiched and fixed between the left surface 12 and the right surface 13 of the door frame 10. That is, according to Embodiment 23, it becomes possible to provide the water stop device 1 that can improve the water tightness maintenance effect and the installation certainty in response to the tolerances of the door frame 10 and the water stop wall 1. In addition, an effect is also obtained in that the influence of the reduction in the water tightness maintenance effect due to the secular deterioration of the water tightness maintenance means 3 and 4 can be reduced.

[0120] In addition, as shown in FIG. 27, if a surface pressure member 6f having a pressing end (pressing surface) 6e with a diameter larger than the area of the pressing end 6e formed by the tip of the bolt 6c is provided on the tip side of the bolt 6c, the pressing end (pressing surface) 6e makes it easy to uniformly press the entire left plate portion 2b or the entire right plate portion 2c. Therefore, the water tightness maintenance effect and the installation certainty can be further improved.

[0121] In addition, in the configuration including the surface pressure member 6f, with the bolt 6c fixed to the mounting base 6a, the surface pressure member 6f itself can move forward and backward in the direction approaching the left plate portion 2b or the right plate portion 2c and in the direction away from the left plate portion 2b or the right plate portion 2c. The surface pressure member 6f may be attached to the tip side of the bolt 6c.

[0122] Embodiment 24 As shown in FIGS. 28 and 29, the water stop device 1 has a configuration including a support portion for assisting accurate and reliable installation work in the installation work of the water stop device 1, and an installation work support portion 99 that also functions as a reinforcement device for reinforcing the lower locking portion 8 and the lower plate portion 2d. That is, the water stop wall 2 includes a wall plate portion 2a, a left locking portion 6, a right locking portion 7, and a lower locking portion 8, and on the upper surface of the lower plate portion 2d from the lower end of the wall surface 21a of the wall plate portion 2a to the lower locking portion 8, there is provided an installation work support portion 99 for assisting the installation work of the water stop device 1.

[0123] The installation work support portion 99 is formed using, for example, a synthetic resin such as hard polyvinyl chloride (H-PVC), rubber, or the like. The installation work support part 99 may be provided across the entire length in the left - right direction between the left plate part 2b and the right plate part 2c on the upper surface of the lower plate part 2d as shown in FIGS. 28 and 29(b), or may be provided intermittently along the left - right direction between the left plate part 2b and the right plate part 2c as shown in FIG. 29(c). The installation work support part 99 is constituted by, for example, a bar - shaped member that is long in the left - right direction and has a right - angled triangular cross - section, including a lower surface 99a facing the upper surface of the lower plate part 2d, a rear surface 99b that extends upward from the rear - end edge of the lower surface 99a and faces the front wall surface 21a of the wall plate part 2a, and an inclined surface 99s that connects the upper - end edge of the rear surface 99b and the front - end edge of the lower surface 99a. The inclined surface 99s is formed by, for example, an uneven surface that repeats unevenness along the inclined direction. Then, in the installation work support part 99, for example, the opposing lower surface 99a and the upper surface of the lower plate part 2d are adhered with an adhesive or the like, and the opposing rear surface 99b and the front wall surface 21a of the wall plate part 2a are adhered with an adhesive or the like, so that it has a configuration integrated with the water - stop wall 2. Note that only the opposing lower surface 99a and the upper surface of the lower plate part 2d may be adhered with an adhesive or the like, or only the opposing rear surface 99b and the front wall surface 21a of the wall plate part 2a may be adhered with an adhesive or the like.

[0124] In the case of the water - stop device 1 having a configuration without the installation work support part 99, when installing the water - stop device 1 in the inner opening 11, if the adhesion between the left watertight - maintenance means 3 and the left surface 12 of the door frame 10 and the adhesion between the right watertight - maintenance means 4 and the right surface 13 of the door frame 10 are high, as shown in FIG. 30(a), just pressing the water - stop device 1 by hand makes it difficult for the force F to be effectively applied downward, and there is a possibility that the lower - end side of the water - stop device 1 cannot be accurately installed at a predetermined position. For example, it may be installed in a state where the lower watertight - maintenance means 5 of the water - stop device 1 and the lower surface 15 of the door frame 10 are not in close contact, and there is a possibility that the watertight performance cannot be maintained. On the other hand, according to the water stop device 1 configured with the installation work support part 99 according to the 24th embodiment, when installing the water stop device 1 in the inner opening 11, an operator steps on the installation work support part 99 with a foot as indicated by the white arrow F in Fig. 30(b), so that a force for pushing down the water stop device 1 is surely transmitted to the water stop device 1. Therefore, the lower end side of the water stop device 1 is accurately installed at a predetermined position. That is, the water stop device 1 is installed in a state where the watertight maintenance means 5 on the lower side of the water stop device 1 is in close contact with the lower surface 15 of the door frame 10, and the watertight performance can be sufficiently exhibited. That is, according to the water stop device 1 according to the 24th embodiment, accurate installation work of the water stop device 1 with respect to the inner opening 11 of the door frame 1 can be surely and easily performed.

[0125] In addition, in the case of the water stop device 1 configured without the installation work support part 99, when the water stop device 1 is dropped onto a surface S such as the ground, the floor surface, or the surface of a mounting table for some reason as indicated by the arrow D in Fig. 30(c), the lower locking part 8 and the lower plate part 2d may be bent or damaged. On the other hand, according to the water stop device 1 configured with the installation work support part 99 according to the 24th embodiment, when the water stop device 1 is dropped onto the surface S as indicated by the arrow D in Fig. 30(d), the installation work support part 99 functions as a reinforcing part for the lower locking part 8 and the lower plate part 2d. Therefore, it is possible to provide the water stop device 1 in which the lower locking part 8 and the lower plate part 2d are hardly damaged.

[0126] Note that in the water stop device 1 according to the present invention, it goes without saying that the water stop device 1 may be configured by combining two or more of the configurations of the above-described first to 24th embodiments.
