[0003] [Patent Document 1] Japanese Patent Application Publication No. 2019-78086 Summary of the Invention [Problem to be solved by the invention]

[0004] Water stop devices are used when water disasters such as heavy rain or floods are expected to occur, and for this reason, it is desirable that the opening under normal conditions have a large opening width with no installation frames on the left and right sides to ensure sufficient traffic volume, etc.

[0005] An object of the present invention is to provide a water stop device that can normally have an opening with a large opening width without left and right installation frames arranged on the left and right sides. [Means for solving the problem]

[0006] The water stopping device of the present invention is a water stopping device comprising left and right installation frames attached to the left and right sides and a bottom surface in order to prevent water from passing through an opening, and a water stopping panel installed between these installation frames so as to be separable from these installation frames, wherein the left and right installation frames are detachable from the left and right sides.

[0007] In this way, in the water stop device of the present invention, the left and right installation frames are detachable from the left and right side surfaces, so when a water disaster such as heavy rain or flooding is expected, the left and right installation frames can be placed on the left and right sides and a water stop panel can be placed between these installation frames to prevent water from passing through the opening.Furthermore, when the risk of a water disaster occurring has disappeared or the water disaster has been resolved, the water stop panels can be separated from the left and right installation frames, and then the left and right installation frames can be removed from the left and right side surfaces, thereby restoring the opening to its normal state with a large opening width when the left and right installation frames are not placed on the left and right sides.

[0008] In the water stopping device according to the present invention, the configuration that allows the left and right installation frames to be attached and detached to the left and right side surfaces can be of any type or structure, and one example of such a configuration is to detachably attach the left and right installation frames to the left and right side surfaces using fasteners such as bolts. Another example of such a configuration is to provide a pressing means on the water stopping panel for pressing the left and right installation frames against the left and right side surfaces, and by pressing the left and right installation frames against the left and right side surfaces using the pressing force of this pressing means, these installation frames can be attached to the left and right side surfaces, and by releasing the pressing force of the pressing means, the left and right installation frames can be removed from the left and right side surfaces.

[0009] Furthermore, among these, if the configuration that allows the left and right installation frames to be attached and detached to the left and right side surfaces is achieved by the latter pressing means provided on the water-stopping panel, this pressing means may be common to both the left and right installation frames, i.e., it may press the left and right installation frames against the left and right side surfaces simultaneously, or it may be provided on the water-stopping panel for each of the left and right installation frames.

[0010] Of these, if a pressing means is provided on the water-stopping panel for each of the left and right installation frames, when the left and right installation frames are pressed against the left and right sides by the pressing force of the pressing means, the water-stopping panel can be fixed to the left and right installation frames by the reaction force that reacts against the pressing force of each pressing means, and when the pressing force is released, the reaction force also disappears, so the water-stopping panel can be separated from the left and right installation frames.

[0011] In addition, the pressing means provided on the water stop panel for each left and right installation frame to press the left and right installation frames against the left and right sides may be of any type or structure, and one example of such a pressing means is an extendable rod means that can be extended and retracted, such as a cylinder and piston rod, and another example of such a pressing means is a screw type that includes a female screw member arranged on the water stop panel and a male screw member that is screwed into the female screw member toward the installation frame and is rotated to move forward and press the installation frame.

[0012] Of these, if the pressing means provided on the water-stopping panel for each left and right installation frame to press the left and right installation frames against the left and right sides is a screw-type member consisting of the latter female screw member and male screw member, the overall structure can be simplified and the work of pressing the left and right installation frames against the left and right sides can be easily carried out.

[0013] In addition, in order to press the left and right installation frames against the left and right side surfaces, the pressing means provided on the water stop panel for each left and right installation frame may be configured to include a slide member arranged on the water stop panel so as to be able to slide freely toward the installation frame, and a pressure member for applying pressure to this slide member toward the installation frame and moving it forward, so that the pressure applied by this pressure member causes the slide member to move forward and press the installation frame.

[0014] In this way, in order to press the left and right installation frames against the left and right side surfaces, if the pressing means provided on the waterstop panel for each left and right installation frame is configured to include a slide member and a pressure member for pressing the slide member toward the installation frame and moving it forward, the pressure member may be any member that can press the slide member toward the installation frame and move it forward, and the pressure member may be, for example, a rotating cam member that has a common rotation center axis with a rotation operating member that is rotated to rotate the rotation cam member, and by arranging the rotation center axis provided at the center of the rotation operating member at a position eccentric to the center of the rotation cam member, the slide member will move forward and press the installation frame due to the pressure applied by the rotation cam member rotated around this rotation center axis.

[0015] Furthermore, in the case where the pressing means provided on the water stop panel for each left and right installation frame to press the left and right installation frames against the left and right side surfaces as described above is configured to include a slide member and a pressure member for pressing this slide member toward the installation frame and moving it forward, the pressure member may be a linear movement operating member that has an inclined portion inclined with respect to the sliding direction of the slide member and is operated to move linearly in a direction that forms an angle with both the sliding direction of the slide member and the inclination direction of the inclined portion, and when this linear movement operating member is operated to move linearly, the pressing force from the inclined portion causes the slide member to move forward and press the installation frame.

[0016] Furthermore, when the slide member and the linear movement operating member are respectively provided on the water-stopping panel for each of the left and right installation frames, and the two linear movement operating members are arranged separately on the left and right sides of the water-stopping panel, these linear movement operating members can be connected by a connecting member, and by operating this connecting member, the two linear movement operating members can be moved linearly simultaneously.

[0017] With this, even if the two linear movement operating members are arranged separately on the left and right sides of the water-stopping panel, by operating the connecting member with one hand, the two linear movement operating members can be moved linearly at the same time, and pressure can be applied to each of the slide members provided on the water-stopping panel for each of the left and right installation frames, so that these slide members can press the left and right installation frames against the left and right side surfaces at the same time.

[0018] Furthermore, as described above, when the pressing means provided on the water stop panel for each left and right installation frame to press the left and right installation frames against the left and right side surfaces is configured to include a slide member and a pressure member for pressing this slide member toward the installation frame to move it forward, and the pressure member is a linear movement operating member that has an inclined portion inclined with respect to the sliding direction of the slide member and is operated to move linearly in a direction that forms an angle with both the sliding direction of the slide member and the inclination direction of the inclined portion, and when this linear movement operating member is operated to move linearly, the sliding member moves forward due to the pressing force from the inclined portion and presses the installation frame, the linear movement operating direction of the linear movement operating member for moving the slide member forward may be any direction.

[0019] Furthermore, when the linear movement operating direction of the linear movement operating member for advancing the slide member is downward, a lower sealing member for waterproof sealing between the water stop panel and the bottom surface of the opening can be attached to the underside of the water stop panel, and when the water stop panel is lowered by linearly moving the linear movement operating member downward, the lower sealing member is compressed between the water stop panel and the bottom surface of the opening, thereby waterproofing the space between the water stop panel and the bottom surface of the opening with the lower sealing member.

[0020] This means that the linear movement operating member can be used to simultaneously pressurize the slide member provided on the water-stopping panel to press the left and right installation frames against the left and right sides, and compress the lower sealing member between the water-stopping panel and the bottom surface of the opening to create a prevention function, by moving the linear movement operating member linearly downward.

[0021] Furthermore, in the water stopping device according to the present invention described above, when a lower sealing member is attached to the underside of the water stopping panel to create a waterproof seal between the water stopping panel and the bottom surface of the opening, a pressing means for pressing down the water stopping panel can be provided on the left and right installation frames, and by pressing down the water stopping panel with this pressing means, the lower sealing member can be compressed between the water stopping panel and the bottom surface of the opening, thereby creating a waterproof seal between the water stopping panel and the bottom surface of the opening with the lower sealing member.

[0022] When the water stopping device of the present invention is equipped with such a pushing-down means, the pushing-down means may have a large dimension in the left-right direction and be common to both the left and right installation frames, or the pushing-down means may be provided for each of the left and right installation frames.

[0023] Of these, if the push-down means is provided on each of the left and right installation frames as in the latter case, the push-down means can be made compact with a small dimension in the left-right direction.

[0024] Furthermore, such pushing-down means can be configured in any type and structure, and one example of a pushing-down means is configured to include a wedge receiving member provided on the left and right installation frames and a wedge that is inserted between the wedge receiving member and the water-stopping panel to push down the water-stopping panel, and another example of a pushing-down means is configured to include a female screw member arranged on the installation frame and a male screw member that is screwed downward into the female screw member toward the water-stopping panel and is rotated to move forward and push down the water-stopping panel.

[0025] Of these, if the pushing-down means is configured to include a female screw member and a male screw member as in the latter, the lower sealing member can be compressed between the water-stopping panel and the bottom surface of the opening, and the work of waterproofing the space between the water-stopping panel and the bottom surface of the opening using this lower sealing member can be easily carried out while checking the amount of compression of the lower sealing member.

[0026] Furthermore, in the water stopping device according to the present invention described above, left and right side sealing members may be arranged on at least one of the left and right installation frames and the water stopping panel, which are compressed between the left and right installation frames and the water stopping panel when the water stopping panel is moved in the direction of penetration of the opening.

[0027] According to this, when the work to move the water stop panel in the direction of penetration of the opening is performed to install the water stop panel between the left and right installation frames, the left and right side sealing members are compressed between the left and right installation frames and the water stop panel, thereby creating a waterproof seal between the left and right installation frames and the water stop panel, and the work to create this waterproof seal can be carried out as work to install the water stop panel between the left and right installation frames.

[0028] The water stop device according to the present invention as described above can be used in any opening into which water may enter during heavy rain, floods, etc. This opening may be, for example, an opening that serves as an entrance inside a door frame that is opened and closed by a door of a swing door device, or an opening that serves as a passageway, or any other opening that serves as an entrance and exit, etc. The entrance and exit may also be an entrance and exit that is opened and closed by a door of a sliding door device or a folding door device, or an above-ground entrance and exit that leads to an underground mall, subway, etc. [Effects of the Invention]

[0029] According to the present invention, it is possible to obtain the effect that the opening in normal times can have a large opening width with no left or right installation frames arranged on the left or right side surfaces. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0031] An embodiment of the present invention will be described below with reference to the drawings. Fig. 1 shows the entirety of a swing door device to which a water stop device according to one embodiment of the present invention is applied. This swing door device is an entrance door in which door 1 is attached to door frame 2 by hinges 3 so that it can be opened and closed freely, and Fig. 2 shows the state of door frame 2 when door 1 is open. Doorway 4 inside door frame 2, which is located at the entrance that forms the boundary between the inside and outside of the room, is an opening in this embodiment that is opened and closed by door 1.

[0032] 1 and 2, the door frame 2 is a four-sided frame made up of left and right side frame members 5, 6 and upper and lower top and bottom frame members 7 and 8. The left and right side frame members 5, 6 form the left and right side surfaces of the doorway 4, the bottom frame member 8, which is a door-sill member, forms the bottom surface of the doorway 4, and the top frame member 7 forms the top surface of the doorway 4. As shown in FIG. 2, the left and right side frame members 5, 6, the top frame member 7, and the bottom frame member 8 are provided with doorstops 5A, 6A, 7A, and 8A that determine the fully closed position of the door 1 by abutting against them when the door is closed, and airtight members 9, 10, 11, and 12 are arranged on these doorstops 5A, 6A, 7A, and 8A to ensure airtightness between the door 1 and the door frame 2 when closed.

[0033] Of the airtight members 9, 10, 11, and 12, the airtight members 9 and 10 arranged on the doorstop portions 5A and 6A of the left and right side frame members 5 and 6 are also shown in FIG. 5, which will be described later.

[0034] FIG. 3 is a front view, as seen from outside the room, of the water stop device 20 of this embodiment set in the lower portion of the entrance 4 with the door 1 open, blocking this portion. The water stop device 20 includes two mounting frames 21, one on each side, disposed on the left and right side frame members 5, 6 of the door frame 2, and a water stop panel 22 disposed between these mounting frames 21. FIG. 4 shows the water stop device 20 as seen from inside the room, and FIG. 5 is a cross-sectional view taken along line S5-S5 in FIG. 3. As shown in FIGS. 3 to 5, the two mounting frames 21 are erected on the upper surface of the doorstop portion 8A of the bottom frame member 8 forming the bottom surface of the entrance 4 and are disposed along the side frame members 5, 6 forming the left and right side surfaces of the entrance 4. The pair of mounting frames 21 is configured to have a symmetrical shape and structure, with the same or approximately the same height as the water stop panel 22.

[0035] Of the two left and right installation frames 21 thus configured to have a symmetrical shape and structure, Fig. 6 shows the installation frame 21 on the left side in Fig. 3, with Fig. 6(A) being a plan view, Fig. 6(B) being a front view as seen from the outside of the room, and Fig. 6(C) being a right side view. Of the components that make up the installation frame 21, the main body 25, which is a bent piece of sheet metal, has the same or approximately the same height as the water stop panel 22. In addition, this main body 25 has an angled shape consisting of a side portion 25A whose width direction is the penetration direction of the entrance / exit 4, and an extension portion 25B that bends at a right angle from the outside end of this side portion 25A and extends outward in the width direction of the entrance / exit 4, which is in the left-right direction.

[0036] Two upper and lower pin members 26, 27 are provided on side portion 25A of main body 25, protruding inward in the width direction of entranceway 4 at the same position in the penetration direction of entranceway 4, and further, a facing member 28, which will face water stop panel 22 on the indoor side in the penetration direction of entranceway 4, is attached to side portion 25A at a position on the indoor side of upper pin member 26 and lower pin member 27, as will be understood from the explanation below, in a state where it protrudes inward in the width direction of entranceway 4 from side portion 25A, and this facing member 28 has the same height as main body 25. Furthermore, an outer seal member 29 is fixed to the outer surface of side portion 25A on the outside in the width direction of entranceway 4 over the entire vertical length of main body 25, and a bottom seal member 30 is fixed to the underside of main body 25 and facing member 28, i.e., to the underside of the entire installation frame 21.

[0037] A push-down device 31 for pushing down the waterstop panel 22 is disposed on the top surface of the facing member 28, which is rectangular in plan view. The push-down device 31, provided for each of the two left and right mounting frames 21, is a screw-type device whose main components are a male screw member 32 and a support member 33 supporting the male screw member 32. The support member 33 has a generally U-shaped overall shape and is composed of a lower portion 33A fixed to the top surface of the facing member 28, a rising portion 33B rising from the indoor end of the lower portion 33A, and an upper portion 33C extending from the top end of the rising portion 33B toward the outdoor side parallel to the lower portion 33A. The upper portion 33C, which extends further toward the outdoor side than the lower portion 33A, has a female screw portion 34 at its tip into which the downward-facing male screw member 32 is threaded. Therefore, the support member 33 is a female screw member into which the male screw member 32 is threaded and supported.

[0038] A knob member 32A for rotating the male screw member 32 is fixed to the upper end of the male screw member 32, and a contact member 32B is attached to the lower end of the male screw member 32 so as to be rotatable relative to the male screw member 32. The contact member 32B contacts the upper surface of the water stop panel 22 when the male screw member 32 is rotated by the knob member 32A and moves downward, i.e., toward the water stop panel 22.

[0039] 7 and 8 show only the water stop panel 22, with Fig. 7 being a front view of the water stop panel 22 as seen from the outside of the room, and Fig. 8 being a back view of the water stop panel 22 as seen from the inside of the room. As shown in Fig. 7, pressing means 35 are arranged on the outside surface 22A of the water stop panel 22 near both left and right ends of the water stop panel 22 for pressing each of the mounting frames 21 against the left and right side frame members 5, 6 of the door frame 2. A plurality of pressing means 35 are provided in the vertical direction, two in this embodiment, and the pressing means 35 provided near both left and right ends of the water stop panel 22 are configured to have a symmetrical shape and structure.

[0040] Like the push-down means 31, each pressing means 35 is a screw-type member whose main components are a male screw member 36 and a support member 37 that supports the male screw member 36. The support member 37 is a U-shaped member consisting of a base 37A fixed to the exterior surface 22A of the waterstop panel 22 and two extension portions 37B extending outward from both left and right ends of the base 37A. Each extension portion 37B is formed with a female screw portion 38 (see also Figure 5), and the male screw member 36 is threaded into these female screw portions 38 in a horizontal direction, toward the outside of the width direction of the doorway 4, which is the side on which the installation frame 21 is disposed. Therefore, the support member 37 is a female screw member into which the male screw member 36 is threaded and supported.

[0041] A knob member 36A for rotating the male screw member 36 is fixed to the inner end of the male screw member 36 in the width direction of the entrance / exit 4, and a contact member 36B is attached to the outer end of the male screw member 32 in the width direction of the entrance / exit 4 so as to be rotatable relative to the male screw member 36. The contact member 36B contacts the main body 25 of the installation frame 21 when the male screw member 36 is rotated by the knob member 36A and moves forward toward the outside of the width direction of the entrance / exit 4, i.e., toward the installation frame 21.

[0042] As shown in Figure 8, two left and right side seal members 40, each having a length in the vertical direction, are fixed to the interior-facing surface 22B of the waterstop panel 22 at or near both left and right ends of the waterstop panel 22, and these side seal members 40 reach from the top to the bottom of the waterstop panel 22. A lower seal member 41, also having a length in the horizontal direction, is fixed to the underside of the waterstop panel 22, and both longitudinal ends of this lower seal member 41 are connected to the lower ends of the two left and right side seal members 40 by connecting seal members 42, so that the two left and right side seal members 40 and the lower seal member 41 form part of a continuous strip seal.

[0043] Figure 9 is a left side view of the waterstop panel 22 in Figure 7. As can be seen from Figure 9, as well as Figures 7 and 8, two guide means 44, 45 are arranged above and below on both the left and right side surfaces of the waterstop panel 22 to guide the pin members 26, 27 that are provided, one above the other, on the installation frame 21. These guide means 44, 45 have the same shape and structure and are provided on both the left and right side surfaces of the waterstop panel 22.

[0044] 9, of the two guide means 44, 45, the upper guide means 44 is made up of an upper portion 44A and a lower portion 44B that are connected by a connecting portion 44C and separated into upper and lower portions, the upper portion 44A being a guide portion that guides a lifting member 46 so that it can be raised and lowered freely up and down, and the lifting member 46 is constantly elastically biased downward by an elastic member 47 such as a coil spring that is stretched between the upper portion 44A and the lifting member 46. Furthermore, the lifting member 46 can be pulled upward against the elastic force of the elastic member 47 by operating an operating portion 46A formed by bending the upper end, and the lower portion of the lifting member 46 has a recess 46B that opens downward and is sized to allow the upper pin member 26 of the pin members 26, 27 of the installation frame 21 to be inserted therein. A downwardly projecting portion 46C on the indoor side at the lower portion of the lifting member 46 that forms the recess 46B has an inclined portion 46D that slopes obliquely downward from the indoor side to the outdoor side. Also, an inclined portion 48 that slopes obliquely upward from the indoor side to the outdoor side is provided on the upper surface of the lower portion 44B of the upper guide means 44.

[0045] Of the two guide means 44, 45, the lower guide means 45 has an opening 50 that opens to the indoor side, and this opening 50 opens to the indoor side via a passage 51 through which the lower pin member 27 of the pin members 26, 27 of the installation frame 21 can pass, and the upper part 51A and lower part 51B of the passage 51 are parallel to each other and form inclined portions that slope diagonally upward from the indoor side to the outdoor side.

[0046] As described above, the left-right width dimension of the water-stopping panel 22, which has two upper and lower guide means 44, 45 provided on each of the left and right side surfaces, including the guide means 44, 45, is slightly smaller than the left-right dimension between the side portions 25A of the main body 25 of the two left and right mounting frames 21 when these mounting frames 21 are arranged along the side frame members 5, 6 of the door frame 2.As a result, it is possible to insert and position the water-stopping panel 22, which has two upper and lower guide means 44, 45 provided on each of the left and right side surfaces, between the side portions 25A of the main body 25 of the two left and right mounting frames 21.

[0047] To place the watertight device 20 according to this embodiment in the lower portion of the aforementioned doorway 4, which is the opening on the inside of the door frame 2, a worker first brings two installation frames 21 (left and right) from the outside of the room into the doorway 4, as can be seen in Fig. 10, and then installs these installation frames 21 on the upper surface of the doorstop portion 8A of the bottom frame member 8 of the door frame 2, and arranges them along the side frame members 5 and 6. As a result, as shown in Fig. 5, the outer seal member 29 fixed to the side portion 25A of the main body 25 of the installation frame 21 contacts the side surfaces of the doorway 4 on the doorstop portions 5A and 6A of the side frame members 5 and 6 that form the left and right sides of the doorway 4, and the lower seal member 30 fixed to the lower surface of the installation frame 21 contacts the upper surface of the doorstop portion 8A of the bottom frame member 8, as shown in Fig. 10.

[0048] Next, the worker performs the installation work by inserting the water stop panel 22 between the side portions 25A of the main bodies 25 of the two left and right installation frames 21. The first step in this work is to bring the water stop panel 22 close to the installation frame 21 while lifting the water stop panel 22 to a position higher than the bottom frame member 8 of the door frame 2, so that of the upper pin members 26 and lower pin members 27 provided on the two left and right installation frames 21, the upper pin member 26 is placed on the inclined portion 48 formed on the lower portion 44B of the upper guide means 44 provided on both the left and right side surfaces of the water stop panel 22, as shown by the two-dot chain line in Fig. 11, and the lower pin member 27 is placed on the lower portion 51B of the passage 51 of the lower guide means 45 provided on both the left and right side surfaces of the water stop panel 22, as shown by the two-dot chain line in Fig. 11,

[0049] After this, the worker moves the water-stopping panel 22 diagonally downward from the outside to the inside of the room, while guiding the two upper and lower pin members 26, 27 by the inclined portion 48 and the lower portion 51B, which each incline diagonally upward from the inside to the outside of the room, so that the upper pin member 26 and the lower pin member 27 reach the upper positions of the inclined portion 48 and the lower portion 51B, respectively, as shown by the dotted line in Figure 11 as the upper pin member 26'' and the lower pin member 27''.

[0050] Furthermore, when an operator moves the water-stopping panel 22 diagonally downward from the outside to the inside of the room, the upper pin member 26 abuts against the inclined portion 46D of the downward protrusion 46C of the lifting member 46 of the upper guide means 44. Because this inclined portion 46D is inclined diagonally downward from the inside to the outside of the room, the lifting member 46 slides upward against the elastic force of the elastic member 47 due to the pressing force from the pin member 26. As a result, the upper pin member 26 enters the interior of the downward-opening recess 46B of the lifting member 46, as shown in Figure 12, and the lifting member 46 slides downward due to the elastic force of the elastic member 47. When the lifting member 46 slides downward due to the elastic force of the elastic member 47 in this way, the upper pin member 26 is inserted into the recess 46B of the lifting member 46, which is slidable only in the up and down direction, and the water stop panel 22 is unable to move in the direction through the doorway 4, which is the opening on the inside of the door frame 2. At this time, the lower pin member 27 reaches the inside of the opening 50 that opens to the indoor side through the passage 51 in the lower guide means 45, as shown in Figure 12.

[0051] The work performed by the worker on the water stop panel 22 as described above is to move the water stop panel 22 from the outside to the inside of the room in the direction of penetration of the entrance / exit 4 inside the door frame 2, and while moving the water stop panel 22 from the outside to the inside of the room, the water stop panel 22 is moved diagonally downward, so that the lower seal member 41 fixed to the underside of the water stop panel 22 comes into contact with the upper surface of the door stop portion 8A of the lower frame member 8, and the two left and right side seal members 40 provided on the indoor side surface 22B of the water stop panel 22 are compressed by the opposing members 28 that face the indoor side surface 22B of the water stop panel 22 and the penetration direction of the entrance / exit 4, among the members that make up each of the two left and right installation frames 21.

[0052] Therefore, by installing the water-stopping panel 22 between the two left and right installation frames 21, the two left and right side sealing members 40 can be compressed by the indoor side surface 22B of the water-stopping panel 22 and the facing member 28, and these side sealing members 40 can create a waterproof seal between the two left and right installation frames 21 and the water-stopping panel 22.

[0053] In addition, the lower guide means 45 provided on both the left and right sides of the water-stopping panel 22 are also provided with lifting members similar to the lifting members 46 provided on the upper guide means 44 described above, so that the lower pin member 27 can be inserted into the downward-opening recess of the lifting member which is provided on the lower guide means 45 so as to be able to slide freely only in the vertical direction and is constantly elastically biased downward by an elastic member such as a spring, thereby making it possible for the lower part of the water-stopping panel 22 to be unable to move in the direction of penetration of the entrance / exit 4.

[0054] After this, the worker performs the work of pressing down the waterstop panel 22 using the pressing down means 31 provided on each of the two left and right mounting frames 21. This work is performed by rotating the knob member 32A of the pressing down means 31 provided on each mounting frame 21 (see FIG. 6 ). This rotates the male screw member 32 that is threaded toward the waterstop panel 22 into the female screw portion 34 of the support member 33, which is the aforementioned female screw member, so that the abutment member 32B provided at the lower end of the male screw member 32 abuts against the upper surface of the waterstop panel 22. Further rotation of the knob member 32A presses down the waterstop panel 22 due to the downward pressing force from the male screw member 32 of the pressing down means 31 provided on each of the two left and right mounting frames 21. As a result, the lower seal member 41 fixed to the lower surface of the waterstop panel 22 is compressed between the lower surface of the waterstop panel 22 and the upper surface of the door stop portion 8A of the bottom frame member 8 of the door frame 2.

[0055] This allows the lifting member 46 of the upper guide means 44 to slide freely upward against the elastic force of the elastic member 47, and even if the vertical dimensions of the opening 50 of the lower guide means 45 are larger than the diameter of the lower pin member 27, the lower seal member 41 can provide a waterproof seal between the water-stopping panel 22 and the lower frame member 8.

[0056] Next, the worker performs work to press the two left and right installation frames 21 against the left and right side frame members 5, 6 of the door frame 2 using multiple pressing means 35 provided on the top and bottom near both left and right ends of the water-stopping panel 22 on the outdoor side surface 22A of the water-stopping panel 22. As can be seen from Figure 5, this operation is performed by rotating the knob member 36A of each pressing means 35, which causes the male screw member 36, which is screwed sideways toward the installation frame 21 into the female screw portion 38 of the support member 37, which is the aforementioned female screw member, to rotate, and the abutment member 36B provided at the tip of the male screw member 36 abuts against the side portion 25A of the main body 25 of the installation frame 21.When the knob member 36A is further rotated, the lateral pressing force from the male screw member 36 of each pressing means 35 provided near both left and right ends of the watertight panel 22 presses the side portion 25A of each of the main bodies 25 of the two left and right installation frames 21 outward in the width direction of the entrance / exit 4, and as a result, the outer surface sealing member 29 provided on the outer surface of the side portion 25A of the main body 25 comes into strong contact with the inner side of the entrance / exit 4 at the door stop portions 5A, 6A of the left and right side frame members 5, 6 of the door frame 2.

[0057] As a result, the outer seal members 29 create a waterproof seal between the two left and right installation frames 21 and the left and right side frame members 5, 6, and the two left and right installation frames 21 are attached to the left and right side frame members 5, 6 of the door frame 2 by the pressing force from the pressing means 35. At this time, as described above, the bottom seal members 30 fixed to the bottom surface of the installation frames 21 are in contact with the top surface of the door stop portion 8A of the bottom frame member 8 of the door frame 2, so that the bottom seal members 30 also create a waterproof seal between the installation frames 21 and the bottom frame member 8.

[0058] In addition, before pressing down the water-stopping panel 22 with the pressing means 31, the two left and right installation frames 21 can be pressed against the left and right side frame members 5, 6 with their respective pressing means 35, and then the water-stopping panel 22 can be pressed down with the pressing means 31, thereby pressing down each installation frame 21 connected to the water-stopping panel 22 by the pressing means 35 together with the water-stopping panel 22 with the pressing means 31, thereby more reliably waterproofing the space between the installation frame 21 and the lower frame member 8 with the underside sealing member 30.

[0059] As described above, when the pressing means 35 provided near both left and right ends of the waterstop panel 22 are used to press the two left and right mounting frames 21 against the left and right side frame members 5, 6 of the door frame 2, reaction forces acting as counteractions to the pressing forces of the respective pressing means 35 act on the waterstop panel 22. These reaction forces act on the waterstop panel 22 as loads in opposite directions toward the inside of the width direction of the doorway 4 in the pressing means 35 provided near both left and right ends of the waterstop panel 22, so when the pressing means 35 press the two left and right mounting frames 21 against the left and right side frame members 5, 6 of the door frame 2, the waterstop panel 22 can be fixed to the two left and right mounting frames 21 by the above loads acting in opposite directions.

[0060] Therefore, by providing the pressing means 35 separately to the two left and right mounting frames 21 on the water-stopping panel 22, it is possible to both press the two left and right mounting frames 21 against the left and right side frame members 5, 6 of the door frame 2 and to fix the water-stopping panel 22 to the two left and right mounting frames 21.

[0061] As described above, the water stop device 20 according to this embodiment is installed below the entrance 4 inside the door frame 2, as shown in Figure 3. Even if water reaches the exterior side of the entrance hall during heavy rain or flooding, the two installation frames 21 on the left and right and the water stop panel 22 can prevent the water from passing through the lower part of the entrance 4 and flowing inside the hall. In addition, as shown in Figure 5, the door 1, which can be freely opened and closed with the hinges 3, can be left open relative to the door frame 2, so that a person can pass through the entrance hall from the exterior side to the interior side or vice versa by stepping over the water stop panel 22.

[0062] Furthermore, the water stop device 20 of this embodiment can be used even when the door 1 is closed against the door frame 2, as shown in Figure 13, so that the closed door 1 can prevent the water stop panel 22 from being damaged by floating objects such as driftwood or other objects that flow along with the water during heavy rain or floods.

[0063] When the risk of a water disaster such as heavy rain or flooding has passed, or when the water disaster has been resolved, the worker reversely rotates the knob members 36A of each pressing means 35, thereby releasing the pressing force acting on the side surfaces 25A of the main bodies 25 of the two left and right installation frames 21 from the male screw members 36 of these pressing means 35. This also eliminates the reaction load acting on the waterstop panels 22 as a reaction to the pressing force of the pressing means 35. Next, the worker reversely rotates the knob members 32A of the press-down means 31 provided on each installation frame 21, thereby moving the abutment members 32B provided on the lower ends of the male screw members 32 of these press-down means 31 upward from the top surface of the waterstop panels 22, thereby releasing the pressing down force on the waterstop panels 22 by the press-down means 31.

[0064] After this, the worker lifts the lifting member 46 attached to the upper guide means 44 of the push-down means 31 by lifting the operating part 46A attached to the upper end of the lifting member 46, thereby lifting the lifting member 46 against the elastic force of the elastic member 47 and moving the waterstop panel 22 diagonally upward from the inside of the room to the outside of the room. As a result, the two pin members 26, 27 attached to the top and bottom of each mounting frame 21 are separated from the upper guide means 44 and lower guide means 45 attached to the left and right sides of the waterstop panel 22, allowing the waterstop panel 22 to be separated from the two left and right mounting frames 21. In addition, the pressing force from the pressing means 35 attached to the waterstop panel 22 has been released, and the two left and right mounting frames 21 can now be removed from the left and right side frame members 5, 6 of the door frame 2.

[0065] As can be seen from the above explanation, the two left and right installation frames 21 of the water stop device 20 according to this embodiment can be attached to the left and right side frame members 5, 6 of the door frame 2 by the pressing force of the pressing means 35 provided on the water stop panel 22, and can be removed from the side frame members 5, 6 by releasing this pressing force, so that the two left and right installation frames 21 can be attached and detached to these side frame members 5, 6. Therefore, the doorway 4 under normal circumstances can be set in a state in which the installation frames 21 are not positioned on the side frame members 5, 6, and this allows the doorway 4 to have a large opening width.

[0066] 14 shows a pressing means 55 according to another embodiment. The pressing means 55 according to this embodiment is provided on the water stop panel 22 for each installation frame 21 and includes a slide member 57 guided by a plurality of guide members 56 on the exterior surface 22A of the water stop panel 22 and arranged to slide in the width direction of the entrance 4 (i.e., the left-right direction); an elastic member 58 such as a coil spring that constantly elastically biases the slide member 57 inward in the width direction of the entrance 4; a circular knob member 59 integrated with a centrally located pivot shaft 59A and rotatable about the pivot shaft 59A; and a circular rotary cam member 60 arranged spaced apart from the knob member 59 in the axial direction of the pivot shaft 59A. The axial direction of the pivot shaft 59A is the thickness direction of the water stop panel 22, i.e., the direction in which the entrance 4 penetrates.

[0067] The rotating cam member 60 is also integrated with the rotation center shaft 59A, and this rotating cam member 60 is rotatable around the rotation center shaft 59A, but the rotation center shaft 59A is not located in the center of the circular rotating cam member 60, but is located on the rotating cam member 60 at a position eccentric from the center. In other words, the circular knob member 59, which serves as the rotation operation member in this embodiment, and the rotating cam member 60, which is located away from the knob member 59 in the axial direction of the rotation center shaft 59A, share the rotation center shaft 59A, but the rotating cam member 60 is eccentric with respect to the knob member 59. The outer peripheral surface of this rotating cam member 60 abuts at the inner end in the width direction of the doorway 4 of the slide member 57, which is constantly urged inward in the width direction of the doorway 4 by the elastic force of the elastic member 58.

[0068] In the pressing means 55 of this embodiment, when the inner end of the slide member 57 in the width direction of the doorway 4 abuts against a portion of the outer peripheral surface of the rotating cam member 60 that is close to the rotation center axis 59A, the outer end of the slide member 57 in the width direction of the doorway 4 is separated from the installation frame 21. Furthermore, when the knob member 59 of each pressing means 55 is rotated, thereby rotating each rotating cam member 60, and the inner end of the slide member 57 in the width direction of the doorway 4 abuts against a portion of the outer peripheral surface of the rotating cam member 60 that is far from the rotation center axis 59A, and the slide member 57 is slid outward in the width direction of the doorway 4 against the elastic force of the elastic member 58, the outer end of each slide member 57 in the width direction of the doorway 4 presses the installation frame 21, and each installation frame 21 is pressed against the left and right side frame members 5, 6 of the door frame 2. Furthermore, when each of the knob members 59 is rotated in the reverse direction, the slide members 57 slide inward in the width direction of the doorway 4 due to the elastic force of the elastic members 58, and the pressure applied by the slide members 57 to the installation frame 21 is released.

[0069] The rotating cam member 60 in the pressing means 55 of this embodiment also serves as a pressing member for pressing the slide member 57 toward the installation frame 21, and in order to press the slide member 57 toward the installation frame 21 using the rotating cam member 60, the knob member 59, which serves as a rotating operating member, is simply rotated about half a turn around the rotation center axis 59A, so that the pressing means 55 can easily press each installation frame 21 against the left and right side frame members 5, 6 of the door frame 2 in a short time.

[0070] 15 shows a pressing means 65 according to another embodiment. The pressing means 65 according to this embodiment is provided on the water stop panel 22 for each installation frame 21 and includes a slide member 67 that is guided by a plurality of guide members 66 and arranged on the exterior surface 22A of the water stop panel 22 so as to be slidable in the width direction of the entrance / exit 4 (i.e., the left-right direction), an elastic member 68 such as a coil spring that constantly elastically biases the slide member 67 inward in the width direction of the entrance / exit 4, and a push-down member 70 that is guided by a plurality of guide members 69 and is movable in the vertical direction. Each push-down member 70 is operated for linear movement in the vertical direction by an operating unit 70A provided at the upper end of the push-down member 70, and therefore the push-down member 70 serves as a linear movement operating member for the pressing means 65 of this embodiment.

[0071] The inner end face of slide member 67 in the width direction of doorway 4 forms inclined portion 67A that slopes from above to below inward in the width direction of doorway 4, and inclined portion 70B that slopes from above to below inward in the width direction of doorway 4 is also formed on the side portion of push-down member 70 on the slide member 67 side, with these inclined portions 67A and 70B being inclined with respect to the left-right direction that is the sliding direction of slide member 67. Because push-down members 70 are common to slide members 67, of which multiple push-down members 70 are arranged above and below each other on exterior surface 22A of waterstop panel 22, push-down member 70 is provided with the same number of inclined portions 70B as there are slide members 67.

[0072] In addition, the vertical direction, which is the linear movement direction of the push-down member 70, is a direction that forms an angle with both the left-right direction, which is the sliding direction of the slide member 67, and the inclination direction of the inclined portion 67A of the slide member 67 and the inclined portion 70B of the push-down member 70.

[0073] 15 by operating the operating unit 70A, so that when the inclined portion 67A of each slide member 67 abuts against the lower part of the inclined portion 70B of the push-down member 70 due to the elastic force of the elastic member 68, the outer end of each slide member 67 in the width direction of the doorway 4 is separated from the installation frame 21. Also, when the inclined portion 67A of each slide member 67 abuts against the upper part of the inclined portion 70B of the push-down member 70 that is higher than the lower part, each slide member 67 slides outward in the width direction of the doorway 4 against the elastic force of the elastic member 68, so that the outer end of each slide member 67 in the width direction of the doorway 4 presses against the installation frame 21, and the two left and right installation frames 21 are pressed against the left and right side frame members 5, 6 of the door frame 2. Furthermore, when each push-down member 70 is raised by operating the operating unit 70A, each slide member 67 slides inward in the width direction of the entrance / exit 4 due to the elastic force of the elastic member 68, and the pressure applied by the slide member 67 to the installation frame 21 is released.

[0074] The push-down member 70 in the pressing means 65 of this embodiment also serves as a pressing member for pressing the slide member 67 toward the installation frame 21, and by simply moving this push-down member 70 downward in a straight line, the slide member 67 can be pressed toward the installation frame 21, so that the pressing means 65 can easily press each installation frame 21 against the left and right side frame members 5, 6 of the door frame 2 in a shorter time.

[0075] In addition, each push-down member 70 in the pressing means 65 of this embodiment is provided with the same number of inclined portions 70B as the number of slide members 67, multiple of which are arranged vertically on the outdoor surface 22A of the water-stopping panel 22, and therefore these push-down members 70 are common to the multiple slide members 67.Therefore, by pressing down the push-down member 70, the multiple slide members 67 can be simultaneously pressed toward the installation frame 21.

[0076] Furthermore, if the push-down member 70 of the pressing means 65 of this embodiment is pressed down to slide each slide member 67 outward in the width direction of the entrance / exit 4 against the elastic force of the elastic member 68, and then the push-down member 70 is further pressed down strongly, a large downward frictional force is generated between the push-down member 70 and the guide member 69.As a result, the water-stopping panel 22 can be lowered together with the slide member 67 due to this large frictional force, which is greater than the frictional force between the slide member 67 and the installation frame 21.After this, when the push-down operation is released, the water-stopping panel 22 maintains its lowered position together with the slide member 67 due to the large frictional force between the push-down member 70 and the guide member 69.

[0077] Therefore, according to this embodiment, even if the pushing-down means 31 provided on the installation frame 21 of the previous embodiments is omitted, by strongly pushing down the pushing-down member 70, the lower seal member 41 fixed to the underside of the water-stopping panel 22 can be compressed between the underside of the water-stopping panel 22 and the lower frame member 8 of the door frame 2, thereby creating a waterproof seal between the underside of these water-stopping panels 22 and the lower frame member 8.

[0078] Furthermore, when the risk of a water disaster such as heavy rain or flooding has disappeared or the water disaster has been resolved, the worker can raise the push-down member 70 by applying a pushing-up force to the operating part 70A that is greater than the frictional force between the push-down member 70 and the guide member 69, thereby restoring the pressing means 65 of this embodiment to its original state.

[0079] In the embodiment of Fig. 16, the two push-down members 70 of the two pressing means 65 provided on the water stopping panel 22 for each of the two left and right installation frames 21 are connected at their upper ends by a connecting member 71. That is, in the embodiment of Fig. 16, the two push-down members 70 arranged separately on the left and right sides of the exterior surface 22A of the water stopping panel 22 are connected at their upper ends by a connecting member 71.

[0080] According to this embodiment, when the connecting member 71 is pushed down with one hand, the two push-down members 70 arranged at a distance on the left and right can be pushed down simultaneously, and as a result, all of the slide members 67 arranged on the outdoor surface 22A of the water-stopping panel 22 can be slid outward in the width direction of the entrance / exit 4, which is the installation frame 21 side, thereby simultaneously pressing down on the two installation frames 21 on the left and right.Furthermore, by pushing up the connecting member 71 with one hand, the two push-down members 70 arranged at a distance on the left and right can be raised simultaneously, and all of the slide members 67 can be slid inward in the width direction of the entrance / exit 4, thereby simultaneously releasing the pressure on the two installation frames 21 on the left and right by these slide members 67.

[0081] Thus, according to the embodiment of Figure 16, the operator can perform the pressing operation on the two left and right mounting frames 21 with all of the slide members 67 and the release operation of the pressing force from all of the slide members 67 acting on the two left and right mounting frames 21 with one hand, making these operations even easier to perform in an even shorter time.

[0082] In the embodiment of Figures 14 to 16, elastic members 58, 68 for constantly elastically biasing the slide members 57, 67 inward in the width direction of the entrance / exit 4 were stretched between the slide members 57, 67 and the guide members 56, 66, but these elastic members 58, 68 may also be stretched between the slide members 57, 67 and the water-stopping panel 22 on the back side of the slide members 57, 67.

[0083] In addition, in the embodiment of Figures 15 and 16, the push-down means 31 shown in Figures 3 and 5, etc. is omitted, but the push-down means 31 may be provided on the two left and right installation frames 21 in the embodiment of Figures 15 and 16.

[0084] Furthermore, in each embodiment, during normal operation, the two left and right installation frames 21 may be left installed on the side frame members 5, 6 of the entrance / exit 4 as needed, with or without using fixing means such as clamps (not shown). [Industrial Applicability]
