Summary of the Invention

Problems to be Solved by the Invention

[0004] When the water stop device is in use, the water stop rubber is installed in close contact with the structure body by the fitting. On the other hand, there are times when water flowing in cannot be prevented only by bringing the water stop rubber into close contact with the structure body by the fitting.

[0005] An example of the problem to be solved by the present invention is to provide a water stop device with improved water stop performance compared to the prior art.

Means for Solving the Problems

[0006] The water-stopping device of the present invention comprises a plate that blocks an opening connecting the outdoor and indoor sides of a structure, holding members located at both ends of the plate and into which the plate can be inserted, a first elastic member attached to the outer surface of the holding member facing the indoor side, a second elastic member attached to the bottom of the plate, and a plate attached to the bottom end of the plate and extending inclined toward the outdoor side. When an external force in a predetermined direction is applied to the plate, both the plate and the second elastic member deform. With this configuration, for example, when water enters from the outdoor side, the water pressure pushes the plate and compresses the first elastic member. That is, the first elastic member adheres tightly to the structure due to the water pressure of the water entering from the outdoor side. At this time, the water entering from the outdoor side passes over the surface of the plate. Therefore, the water pressure of the water entering from the outdoor side is also applied to the plate. As a result, the plate deforms and adheres tightly to the installation surface. And, along with the deformation of the plate, the second elastic member is also compressed so as to adhere tightly to the installation surface. Therefore, the water-stopping device offers improved water-stopping performance compared to conventional devices.

[0007] In the aforementioned water-stopping device, the plate is made of an elastic material, is detachable from the plate material, and is integrated with the second elastic member. With this configuration, for example, the plate is easily deformed by the water pressure of water entering from the outside.

[0008] The water-stopping device further includes a connecting portion that connects the plate material and the plate, the plate being made of metal and rotatably attached to the plate material via the connecting portion. With this configuration, for example, as the plate deforms, the second elastic member attached to the bottom of the plate material comes into close contact with the installation surface. Therefore, even if a material other than an elastic material is used for the plate, the water-stopping device can improve its water-stopping performance.

[0009] In the aforementioned water-stopping device, a space is provided between the mounting surface that contacts the second elastic member and the plate. With this configuration, for example, when water pressure from water entering from the outside is applied to the plate, the force on the plate and the second elastic member increases. Consequently, the plate and the second elastic member can adhere more closely to the mounting surface.

[0010] In the aforementioned water-stopping device, the amount of deformation of the second elastic member changes according to the size of the space. With this configuration, for example, the second elastic member adheres more tightly to the installation surface as the size of the space increases. This further improves the water-stopping performance of the water-stopping device.

[0011] The plate of the present invention is provided in a water-stopping device comprising: a plate material that blocks an opening connecting the outdoor and indoor sides of a structure; holding members located at both ends of the plate material into which the plate material can be inserted; a first elastic member attached to the outer surface of the holding members facing the indoor side; and a second elastic member attached to the bottom of the plate material. The second elastic member is attached to the bottom end of the plate material, extends inclined toward the outdoor side, and deforms together with the second elastic member when an external force is applied in a predetermined direction. With this configuration, for example, when water enters from the outdoor side, the plate material is pushed by the water pressure, and the first elastic member is compressed. That is, the first elastic member adheres tightly to the structure due to the water pressure of the water entering from the outdoor side. At this time, the water entering from the outdoor side passes over the surface of the plate. Therefore, the water pressure of the water entering from the outdoor side is also applied to the plate. As a result, the plate deforms and adheres tightly to the installation surface. Then, along with the deformation of the plate, the second elastic member is also compressed so as to adhere tightly to the installation surface. Therefore, the plate improves the water-stopping performance of the water-stopping device compared to conventional designs. [Effects of the Invention]

[0012] According to the above embodiment of the present invention, the water-stopping performance of the water-stopping device is improved. [Brief explanation of the drawing]

[Figure 2] Figure 2 is a plan view of the water-stopping device according to the first embodiment. [Figure 3] Figure 3 is a side view of the water-stopping device according to the first embodiment. [Figure 4] Figure 4 is an enlarged view of Figure 3 of the water-stopping device according to the first embodiment.

[Figure 6] Figure 6 is a side view of the water-stopping device according to the second embodiment. [Figure 7] Figure 7 is an enlarged view of Figure 6 of the water-stopping device according to the second embodiment. [Modes for carrying out the invention]

[0014] (Embodiment) The water-stopping device 1 according to the embodiment will be described below with reference to the drawings. The configuration of the embodiment described below, as well as the operation and results (effects) brought about by said configuration, are merely examples and are not limited to the contents described below.

[0015] Furthermore, the multiple embodiments disclosed below include similar components. Therefore, in the following, these similar components are assigned common reference numerals, and redundant descriptions are omitted. In this specification, ordinal numbers are used solely to distinguish parts and components and do not indicate order or priority.

[0016] <First Embodiment> Figure 1 is a perspective view of the water-stopping device 1 of the first embodiment. The water-stopping device 1 of this embodiment is installed, for example, at the lower end of a structure such as a building, and is a device that prevents water from entering the indoor side of the structure from the outdoor side. However, the water-stopping device 1 is not limited to this, and may also be a type of water-stopping device that is directly attached to a shutter or the like.

[0017] As shown in Fig. 1, the water stop device 1 includes two holding members 2, a water stop plate 3, two vertical rubbers 4, two bottom rubbers 5, and a plate 6. Note that the water stop plate 3 is an example of a plate material, and the vertical rubber 4 is an example of a first elastic member. Also, the bottom rubber 5 is an example of a second elastic member.

[0018] In the following figures, for the sake of convenience, three mutually orthogonal directions are defined. The X direction is the direction along the thickness direction of the water stop plate 3, and can also be referred to as the front-back direction. The Y direction is the direction along the width direction of the water stop plate 3, and can also be referred to as the left-right direction. The Z direction is the direction along the height direction of the water stop plate 3, and can also be referred to as the up-down direction. Note that the expressions indicating directions such as front-back, left-right, up-down in this embodiment are for the sake of convenience and do not limit the position, posture, and usage mode of the water stop device 1.

[0019] Fig. 2 is a plan view of the water stop device 1 of this embodiment. The holding member 2 is, for example, a prismatic member formed of a metal such as an aluminum alloy. Note that the holding member 2 is subjected to painting or surface treatment.

[0020] The holding members 2 are arranged to face each other in the left-right direction (Y direction). At this time, the distance between the holding members 2 is slightly longer than the distance in the width direction of the opening O of the structure where the water stop device 1 is installed. The holding member 2 is detachably attached to the structure body B by a fitting (not shown).

[0021] As shown in Fig. 2, the holding member 2 is provided with a first space 21 and a second space 22. The first space 21 is a space surrounded by a side wall 211. The first space 21 communicates with the outside in the up-down direction (Z direction). Also, the size of the first space 21 is such that the water stop plate 3 can be inserted.

[0022] The side wall 211 is a part of the holding member 2, extends along the up-down direction (Z direction), and is a substantially flat surface surrounding the first space 21. The side wall 211 has an opening on one side in the left-right direction (Y direction). That is, the cross-sectional shape of the first space 21 is substantially C-shaped.

[0023] The second space 22 is located adjacent to the first space 21 and is enclosed by the side wall 221. Like the first space 21, the second space 22 communicates with the outside in the vertical direction (Z direction). The side wall 221 is an example of an outer surface.

[0024] The side wall 221 is part of the retaining member 2 and includes the side wall 211 of the first space 21. The side wall 221 extends along the vertical direction (Z direction) and is a substantially flat surface surrounding the second space 22. One end of the side wall 221 in the front-rear direction (X direction) is open, and two claw portions 222 are provided projecting in the left-right direction (Y direction) from the tip of the side wall 221 facing the opening, so as to face each other.

[0025] As shown in Figure 1, the water-blocking plate 3 is a rectangular plate made of, for example, an aluminum alloy. The water-blocking plate 3 blocks the opening O that connects the outdoor side and the indoor side of the structure. The water-blocking plate 3 is also insertable into the first space 21. That is, the water-blocking plate 3 is held in place by the retaining members 2. In other words, the retaining members 2 are located at both ends 3a of the water-blocking plate 3. As a result, the water-blocking plate 3 prevents water from entering the structure.

[0026] The water-stopping plate 3 is painted or surface-treated. This prevents the water-stopping plate 3 from rusting due to contact with water. The height of the water-stopping plate 3 is such that a person can step over it, and it is slightly longer than the height of the retaining members 2. Therefore, a portion of the water-stopping plate 3 is exposed to the outside when it is held in place by the retaining members 2. In addition, the width of the water-stopping plate 3 is longer than the width of the opening O, and shorter than the distance between each retaining member 2.

[0027] Figure 3 is a side view of the water-stopping device 1 of this embodiment. Figure 4 is an enlarged view of Figure 3. As shown in Figures 3 and 4, the water-stopping plate 3 is provided with two third spaces 31. The two third spaces 31 are surrounded by the side walls 311 and are located below the water-stopping plate 3 (in the -Z direction). That is, the two third spaces 31 are located at the bottom of the water-stopping plate 3. Each third space 31 is located adjacent to each other in the front-to-back direction (X direction).

[0028] The side wall 311 is part of the water-stopping plate 3, extends along the vertical direction (Z direction), and is a substantially flat surface surrounding the third space 31. The side wall 311 has an opening facing the installation surface F that contacts the bottom rubber 5. One of the third spaces 31 is provided with two claw portions 312 that protrude from the tip of the side wall 311 facing the opening in the left-right direction (Y direction) and face each other.

[0029] The two vertical rubbers 4 are elastic members made of rubber. The material of the vertical rubbers 4 is not limited to rubber; for example, they may be made of other synthetic resins that are easily deformable. The shape of the vertical rubbers 4 is a strip extending in the vertical direction (Z direction). As shown in Figure 2, each vertical rubber 4 has an insertion portion 41 and a protruding portion 42.

[0030] The insertion portion 41 can be inserted into the second space 22 of each holding member 2. The insertion portion 41 has a plurality of stoppers 411. Furthermore, the insertion portion 41 is provided with a hole 412.

[0031] The multiple stoppers 411 extend toward the side wall 221 of the holding member 2 when the insertion portion 41 is inserted into the second space 22. Some of the multiple stoppers 411 are in contact with the claw portion 222. This allows the vertical rubber 4 to maintain its inserted state in the second space 22.

[0032] The hole 412 opens in an elongated shape and communicates with both ends of the vertical rubber 4. As a result, the vertical rubber 4 can be easily removed from the retaining member 2 by inserting a rod-shaped member into the hole 412 and applying force in the opposite direction to the direction in which the vertical rubber 4 was inserted into the second space 22.

[0033] The protruding portion 42 is the part that protrudes to the outside when each vertical rubber 4 is inserted into the second space 22. In other words, the vertical rubber 4 is attached to the side wall 221 of the retaining member 2 that faces the indoor side. The length of the protruding portion 42 in the width direction is such that it can come into contact with the claw portion 222.

[0034] The vertical rubber 4 is attached to the structure together with the retaining member 2 via a metal fitting (not shown). That is, the protruding portion 42 contacts the main body B of the structure when the water-stopping device 1 is attached to the structure. The surface of the protruding portion 42 that contacts the main body B is substantially flat. As a result, the protruding portion 42 seals the gap between the main body B and the vertical rubber 4. Therefore, the protruding portion 42 prevents water from entering through the gap between the main body B and the vertical rubber 4.

[0035] The two bottom rubbers 5 are elastic members made of rubber. However, the material of the bottom rubbers 5 is not limited to rubber; for example, it may be made of other synthetic resins that are easily deformable. The shape of the bottom rubbers 5 is a strip that extends in the left-right direction (Y direction) from one end 3a of the water-stopping plate 3 to the other end 3a.

[0036] As shown in Figure 4, the bottom rubber 5 has an insertion portion 51 and a protruding portion 52. The insertion portion 51 is inserted into one of the two third spaces 31 provided in the water-stopping plate 3. The insertion portion 51 has a plurality of stoppers 511. Furthermore, the insertion portion 51 is provided with holes 512.

[0037] Multiple stoppers 511 extend toward the side wall 311 of the water-stopping plate 3 when the insertion portion 51 is inserted into the third space 31. Some of the multiple stoppers 511 are in contact with the claw portion 312. This allows the bottom rubber 5 to maintain its inserted state in the third space 31.

[0038] The hole 512 opens in an elongated shape and communicates with both ends of the bottom rubber 5. As a result, the bottom rubber 5 can be easily removed from the watertight plate 3 by inserting a rod-shaped member into the hole 512 and applying force in the opposite direction to the direction in which the bottom rubber 5 was inserted into the third space 31.

[0039] The protruding portion 52 is the part that protrudes to the outside when the bottom rubber 5 is inserted into the third space 31. In other words, the bottom rubber 5 is attached to the bottom of the water-stopping plate 3. The width of the protruding portion 52 is such that it can come into contact with the claw portion 312.

[0040] The protruding portion 52 contacts the installation surface F when the water-stopping device 1 is attached to the structure. The surface of the protruding portion 52 that contacts the installation surface F is substantially flat. As a result, the protruding portion 52 seals the gap between the installation surface F and the bottom rubber 5. Therefore, the protruding portion 52 prevents water from entering through the gap between the installation surface F and the bottom rubber 5.

[0041] As shown in Figure 1, the plate 6 is a rectangular plate made of an elastic material such as rubber. The material of the bottom rubber 5 is not limited to rubber; for example, it may be made of another synthetic resin that is easily deformable.

[0042] Plate 6 extends inclined toward the outdoors from the lower end 3b of the water-stopping plate 3 in the downward direction (-Z direction). In other words, plate 6 is attached to the lower end 3b of the water-stopping plate 3. As a result, for example, if an external force is applied to plate 6 in a predetermined direction, both the bottom rubber 5 and plate 6 will deform. Note that the lower end 3b is just one example of an end.

[0043] In this embodiment, as shown in Figure 4, the plate 6 and the bottom rubber 5 are integrally formed. That is, the plate 6 is detachable from the water-stopping plate 3. This makes it possible, for example, to purchase only the plate 6 and retrofit it to a water-stopping device that does not have a plate 6. However, this is not the only option; for example, the plate 6 and the bottom rubber 5 may be provided separately.

[0044] The width of plate 6 is slightly shorter than the width of retaining member 2 when plate 6 is attached to water-stopping plate 3. The height of plate 6 is longer than the height of water-stopping plate 3.

[0045] Furthermore, the height of plate 6 may be even longer than the height of water-stopping plate 3. For example, if the surface area of ​​plate 6 increases, the water pressure exerted on the surface of plate 6 by water will also increase. As a result, the bottom rubber 5 can adhere more firmly to the mounting surface F as plate 6 deforms.

[0046] The tip 61 (outdoor side) of plate 6 is in contact with the mounting surface F. The thickness of the tip 61 is processed to be thinner than the thickness of the rest of the plate. Therefore, the step between the tip 61 and the mounting surface F is small.

[0047] On the other hand, the base side (indoor side) of plate 6 is spaced apart from the mounting surface F. Therefore, a space S is provided between plate 6 and the mounting surface F. That is, space S is the space enclosed by the bottom rubber 5, plate 6, and mounting surface F. Alternatively, a material softer than the bottom rubber 5 may be provided between plate 6 and the mounting surface F instead of space S.

[0048] The size of the space S may be changed as appropriate. In other words, the height of the bottom rubber 5 may be changed as appropriate. For example, if the size of the space S is large, the amount of deformation of the bottom rubber 5, which deforms due to the water pressure, will also be large. In other words, the amount of deformation of the bottom rubber 5 changes according to the size of the space S.

[0049] Figure 5 is a perspective view of the water-stopping device 1 in this embodiment when it is stored. As shown in Figure 5, when storing the water-stopping device 1, the water-stopping device 1 is removed from the structure and stored with the plate 6 folded. At this time, the plate 6 hangs down from the upper end of the water-stopping plate 3. This prevents the surface of the water-stopping plate 3 from being damaged.

[0050] As described above, the water-stopping device 1 of this embodiment is attached to the structural frame B of the structure by a metal fitting (not shown). At this time, the vertical rubber 4 is compressed to adhere tightly to the structural frame B, and the bottom rubber 5 is compressed to adhere tightly to the installation surface F. The tip 61 (outdoor side) of the plate 6 is in contact with the installation surface F, and a space S is created between the plate 6 and the installation surface F on the base side (indoor side) of the plate 6.

[0051] When water attempts to enter from the outside, it is blocked by the water-stopping plate 3. At this time, the water-stopping plate 3 is subjected to the pressure of the water attempting to enter from the outside. As a result, the vertical rubber 4 becomes even more tightly attached to the structure B.

[0052] On the other hand, water pressure is applied downwards to plate 6 by the water passing over its surface. As a result, the bottom rubber 5 sinks towards the mounting surface F by the amount of space S. This causes the entire plate 6 to be in close contact with the mounting surface F. In other words, the bottom rubber 5 is further pressed against the mounting surface F by the water pressure of the water passing over plate 6.

[0053] As described above, the water-stopping device 1 of this embodiment adheres more firmly to the structure B and the installation surface F due to the water pressure of the water attempting to enter. Therefore, the water-stopping device 1 of this embodiment has improved water-stopping performance compared to conventional devices.

[0054] As described above, the water-stopping device 1 of this embodiment comprises a water-stopping plate 3, a retaining member 2, a vertical rubber 4, a bottom rubber 5, and a plate 6. The water-stopping plate 3 blocks the opening O that connects the outdoor side and the indoor side of the structure. The retaining member 2 is located at both ends 3a of the water-stopping plate 3 and into which the water-stopping plate 3 can be inserted. The vertical rubber 4 is attached to the side wall 221 of the retaining member 2 facing the indoor side. The bottom rubber 5 is attached to the bottom of the water-stopping plate 3. The plate 6 is attached to the lower end 3b on the bottom side of the water-stopping plate 3 and extends inclined toward the outdoor side. Furthermore, when an external force in a predetermined direction is applied to the plate 6, both the plate 6 and the bottom rubber 5 deform.

[0055] When water enters from the outside, the water pressure pushes against the water-stopping plate 3, and the vertical rubber 4 is compressed. In other words, the vertical rubber 4 adheres tightly to the structure B due to the water pressure of the water entering from the outside. At this time, the water entering from the outside passes over the surface of the plate 6. Therefore, the water pressure of the water entering from the outside is also applied to the plate 6.

[0056] As a result, the plate 6 deforms and adheres tightly to the mounting surface F. Along with the deformation of the plate 6, the bottom rubber 5 is also compressed to adhere tightly to the mounting surface F. Therefore, the water-stopping device 1 has improved water-stopping performance compared to conventional devices.

[0057] Furthermore, the water-stopping device 1 of this embodiment can stop water from entering from the outside without the need to provide fittings to tightly attach the vertical rubber 4 and bottom rubber 5 to the structural frame B of the structure. Therefore, the water-stopping device 1 does not require fittings. This reduces the burden on the user when installing the water-stopping device 1 on a structure. Consequently, the water-stopping device 1 can improve user convenience.

[0058] Furthermore, in this embodiment, the plate 6 is made of an elastic material such as rubber, is detachable from the water-stopping plate 3, and is integrated with the bottom rubber 5. This makes the plate 6 more susceptible to deformation due to the water pressure of water entering from the outside.

[0059] Furthermore, in this embodiment, a space S is provided between the mounting surface F that contacts the bottom rubber 5 and the plate 6. This increases the force acting on the plate 6 and the bottom rubber 5 when water pressure from water entering from the outside is applied to the plate 6. Consequently, the plate 6 and the bottom rubber 5 can adhere more closely to the mounting surface F.

[0060] Furthermore, in this embodiment, the amount of deformation of the bottom rubber 5 changes according to the size of the space S. For example, if the size of the space S is large, the height of the bottom rubber 5 increases. When water pressure is applied to the bottom rubber 5, the amount of deformation of the bottom rubber 5 becomes larger than usual. As a result, the bottom rubber 5 adheres to the installation surface F with greater force. In other words, the larger the size of the space S, the stronger the force with which the bottom rubber 5 adheres to the installation surface F. This further improves the water-stopping performance of the water-stopping device 1.

[0061] <Second Embodiment> Figure 6 is a side view of the water-stopping device 1A of the second embodiment. As shown in Figure 6, the water-stopping device 1A of the second embodiment has the same configuration as the water-stopping device 1 of the first embodiment, except for the configuration described below. Therefore, the second embodiment also provides the same effects as the first embodiment based on the same configuration.

[0062] In the second embodiment, the water-stopping device 1A has a plate 6A made of a different material than the water-stopping device 1 of the first embodiment. The plate 6A is made of a metal such as an aluminum alloy.

[0063] The surface of plate 6A is painted or surface-treated. This prevents plate 6A from rusting due to contact with water. Plate 6A is extremely thin to allow for easy deformation. When plate 6A is attached to the water stopper 3, the height of plate 6 is approximately equal to the height of the water stopper 3.

[0064] Figure 7 is an enlarged view of Figure 6. As shown in Figure 7, in this embodiment, the plate 6A is not integrated with the bottom rubber 5, but is provided separately. The water-stopping device 1 also further includes a hinge 7 that connects the water-stopping plate 3 and the plate 6A. Note that the hinge 7 is an example of a connecting part. The plate 6A is rotatably attached to the water-stopping plate 3 via the hinge 7.

[0065] The hinge 7 allows the plate 6A to rotate relative to the water-stopping plate 3. In this embodiment, the hinge 7 is attached to the lower end portion 3b of the water-stopping plate 3. In other words, the hinge 7 is attached to the portion of the water-stopping plate 3 that is exposed to the outside when the water-stopping plate 3 is held by the retaining member 2.

[0066] The water-stopping device 1A, like the water-stopping device 1 of the first embodiment, stores the plate 6A in a folded state. The plate 6A rotates around the hinge 7 and is held in contact with the surface of the water-stopping plate 3 by being wrapped around the water-stopping plate 3 with tape or the like. In other words, the plate 6A is maintained in contact with the water-stopping plate 3 by tape or the like. However, the method of maintaining the plate 6A in contact with the water-stopping plate 3 is not limited to this. For example, the plate 6A may have a protrusion on its surface and fit into a recess provided on the surface of the water-stopping plate 3, thereby maintaining the plate 6A in contact with the water-stopping plate 3.

[0067] As described above, in the water-stopping device 1A of this embodiment, water pressure is applied downward to the plate 6A by the water passing over its surface. Since the plate 6A is connected to the water-stopping plate 3 via the hinge 7, the bottom rubber 5 sinks towards the installation surface F by the amount of space S. As a result, the entire plate 6A comes into close contact with the installation surface F. In other words, the bottom rubber 5 comes into even closer contact with the installation surface F due to the water pressure of the water passing over the plate 6A.

[0068] As described above, the water-stopping device 1A of this embodiment adheres more firmly to the installation surface F due to the water pressure of the water attempting to enter. Therefore, the water-stopping device 1A of this embodiment has improved water-stopping performance compared to conventional devices.

[0069] As described above, the water-stopping device 1 of this embodiment further includes a hinge 7 that connects the water-stopping plate 3 and the plate 6A. The plate 6A is made of metal and is rotatably attached to the water-stopping plate 3 via the hinge 7.

[0070] As a result, the bottom rubber 5 attached to the bottom of the water-stopping plate 3 comes into close contact with the installation surface F as the plate 6A deforms. Therefore, even if a material other than an elastic material is used for the plate 6A, the water-stopping device 1 can improve its water-stopping performance.

[0071] <Variation> In the first and second embodiments described above, the space S is in communication with the outside in the left-right direction (Y direction). However, for example, the space between the left-right direction (Y direction) of the plates 6 and 6A and the installation surface F may be covered by a barrier or the like. With such a configuration, water attempting to enter will have difficulty flowing between the bottom rubber 5 and the installation surface F. As a result, the water-stopping performance of the water-stopping devices 1 and 1A is further improved.

[0072] Although embodiments of the present invention have been described above, these embodiments are merely examples and are not intended to limit the scope of the invention. The above embodiments can be implemented in various other forms, and various omissions, substitutions, combinations, and modifications can be made without departing from the spirit of the invention. Furthermore, each configuration, shape, and other specifications (structure, type, direction, form, size, length, width, thickness, height, number, arrangement, position, material, etc.) can be modified as appropriate.
