Summary of the Invention

Problems to be Solved by the Invention

[0004] In the above conventional waterproof door, as a water stop structure between adjacent panels in the vertical direction, a watertight rubber is provided over the entire width direction on the upper end surface of the panel. This watertight rubber has an outdoor side horizontal portion on the outdoor side and an indoor side horizontal portion on the indoor side, and fitting ridges are respectively formed on the lower surfaces of each horizontal portion. By fitting these fitting ridges into the outdoor side fitting groove on the outdoor side of the panel and the indoor side fitting groove on the indoor side of the panel, the water stop rubber is fixed to the upper end surface of the panel.

[0005] By the way, the water stop rubber of such a waterproof door needs to be periodically replaced in order to maintain the water stop performance. However, in the above conventional technology, since the adjacent panels in the vertical direction overlap with each other by the outdoor side vertical piece and the indoor side vertical piece, it is impossible to easily perform the replacement work of the water stop rubber disposed between the panels, and there is room for improvement.

[0006] The present invention has been made in view of the above circumstances, and aims to provide a water-stopping device that can improve the replacement and maintenance work of water-stopping members for each panel of an opening and closing body, and a method for replacing water-stopping members of a water-stopping device. [Means for solving the problem]

[0007] In view of these challenges, one aspect of the present invention comprises the following configuration.

[0008] A water-stopping device comprising: an opening / closing body having a plurality of panels that close in a manner that partitions a space and can be stacked vertically in the closed state; and a water-stopping member attached to the upper or lower end of each of the plurality of panels across the width direction of the opening / closing body, wherein the water-stopping member integrally comprises a held portion made of an elastic material that is held at the upper or lower end of each of the panels, and a sealing portion made of an elastic material that seals water between the panels stacked vertically, and the upper or lower end of each of the panels is formed with a holding portion that holds the held portion of the water-stopping member so as to be insertable and detachable in the thickness direction of the opening / closing body, and a sealing portion support portion that supports the sealing portion of the water-stopping member. [Effects of the Invention]

[0009] As described above, the present invention is configured to improve the replacement and maintenance work of water-stopping members for each panel of the opening / closing body in a water-stopping device. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0011] (First embodiment) Next, embodiments according to the present invention will be described. FIG. 1 is a front schematic view showing an example of a water stop device according to the present invention. FIG. 2 is a longitudinal sectional schematic view taken along line (I)-(I) of FIG. 1, FIG. 3 is a longitudinal sectional schematic view taken along line (II)-(II) of FIG. 1, and FIG. 4 is a cross-sectional schematic view taken along line (III)-(III) of FIG. 1.

[0012] In the following description, "upstream side" means the upstream side in the assumed water flow direction, and "downstream side" means the downstream side in the assumed water flow direction and the opposite side to the upstream side. In this embodiment, it is assumed that water flows from the outdoor side to the indoor side (see FIGS. 2 to 4).

[0013] Also, the "width direction of the opening / closing body" means a direction substantially orthogonal to the opening / closing direction of the opening / closing body and not the thickness direction of the opening / closing body (the left-right direction in FIG. 1), and the "thickness direction of the opening / closing body" means the thickness direction of the opening / closing body (the left-right direction in FIG. 2).

[0014] (Overall configuration of the water stop device) The water stop device 1 is configured, for example, as a water stop device provided at an opening of a building such as a building to block water that attempts to flow from the outdoor side to the indoor side during a flood.

[0015] This water stop device 1 includes, for example, an opening / closing body 10 that closes by partitioning a space, left and right guide rails 20, 20 that guide the ends of the opening / closing body 10 in the width direction of the opening / closing body in the opening / closing direction, a storage portion 30 that extends and stores the opening / closing body 10 above it, a vertical pressing mechanism 40 (electric pressing mechanism) that presses the closed opening / closing body 10 against a lower fixed portion G (for example, a floor surface, ground surface, lower frame, threshold, etc.), a horizontal pressing mechanism 50 (electric pressing mechanism) that presses the closed opening / closing body 10 against the guide rail 20 which is a fixed portion on the downstream side, a deflection suppression device 60 (see FIG. 2) that suppresses the closed opening / closing body 10 from deflecting inward due to water pressure, and a control unit (not shown) that controls the vertical pressing mechanism 40 and the horizontal pressing mechanism 50, etc.

[0016] As shown in Figure 2, the opening / closing body 10 has an upper panel 12 positioned at the top, a lower panel 13 positioned at the bottom, and a plurality of intermediate panels 11 positioned between the upper panel 12 and the lower panel 13. The panels 11 to 13 are sequentially extended in the closing direction by the storage unit 30 and stacked almost vertically on the immovable part G to reach a fully closed state.

[0017] Each panel 11-13 is a long, roughly rectangular plate-shaped member in the width direction of the opening / closing body, and is integrally molded from, for example, an aluminum extruded profile, and is configured to have multiple spaces (cavities) divided vertically. These panels 11-13 are connected in the opening / closing direction via a panel connecting chain 14 and a support shaft 15, etc.

[0018] When the opening / closing body 10 is fully closed, the spaces between the vertically adjacent panels 11 to 13 are in watertight contact via the intermediate watertight member 70, and the lower panel 13 is in watertight contact with the lower immovable part G via the lower watertight member 90. The specific configurations of each panel 11-13 and each water-stopping member 70,90 will be described later.

[0019] As shown in Figure 4, the guide rail 20 has a substantially concave cross-section that extends vertically, surrounding the widthwise end of the opening / closing body 10 in the closed state, and is formed in an elongated shape extending from the lower fixed part G to the storage section 30. Within this guide rail 20 are a motion direction changing mechanism 52 that constitutes the horizontal pressing mechanism 50 described later, and a receiving part 21 that watertightly receives the opening / closing body 10 downstream of it. Furthermore, the guide rail 20 and the receiving part 21 are immovable parts that are fixed downstream of the opening / closing body 10 which is pushed and moved by the horizontal pressing mechanism 50.

[0020] The receiving portion 21 is an elastic body made of rubber or elastomer resin and extends continuously over approximately the entire length of the guide rail 20, both vertically and horizontally. This receiving portion 21 is pressed against the opening / closing body 10 and elastically contracts, improving the watertightness between the opening / closing body 10 and the guide rail 20.

[0021] As shown in Figure 2, the storage unit 30 is fixed to the wall surface of the building structure or other object on which the water-stopping device 1 is installed, above the opening that is opened and closed by the opening / closing body 10. The storage unit 30 supports a sprocket 31 on which a panel connecting chain 14 is wrapped around a base 30a fixed to a stationary wall surface, an electric drive mechanism 32 that rotates the sprocket 31 in both directions, and storage rails 33 that suspend and guide each of the panels 11 to 13 in the front-to-back direction.

[0022] Furthermore, the storage section 30 is provided with a vertical pressing mechanism 40 that presses the fully closed opening / closing body 10 against the immovable part G in a nearly vertical manner, and a horizontal pressing mechanism 50 that presses the fully closed opening / closing body 10 against the receiving part 21 inside the guide rail 20 in a nearly horizontal manner.

[0023] The vertical pressing mechanism 40 is an electrically operated pressing mechanism that electrically presses the closed opening / closing body 10 downwards and presses it against the immovable part G on the closing side. As shown in Figure 1, multiple vertical pressing mechanisms 40 are provided, for example, spaced apart in the lateral width direction of the opening / closing body (two sets of left and right pairs of vertical pressing mechanisms 40).

[0024] As shown in Figure 2, each vertical pressing mechanism 40 includes, for example, an actuator 41 that moves a diagonally downward-facing rod 41a forward and backward using an electric motor, and a link mechanism 42 that rotates a pressing portion 42a in an arc shape as the rod 41a moves forward and backward. The pressing portion 42a, which rotates when driven by the actuator 41, contacts the upper end of the closed opening / closing body 10, thereby pushing the opening / closing body 10 downward. In the illustrated example, each rod 41a of each pair of left and right actuators 41 is connected by a single horizontally elongated pressing portion 42a, and moves forward and backward in synchronous motion.

[0025] The horizontal pressing mechanism 50 is an electrically operated pressing mechanism that pushes the closed opening / closing body 10 and presses it against a stationary part adjacent to the downstream side of the opening / closing body 10 (in the illustrated example, the receiving part 21 in the guide rail 20). As shown in Figure 1, two horizontal pressing mechanisms 50 are provided, for example, corresponding to the left and right guide rails 20, 20, respectively.

[0026] As shown in Figures 3 and 4, each horizontal pressing mechanism 50 includes an actuator 51 that moves a downward rod 51a forward and backward using an electric motor, a motion direction conversion mechanism 52 that converts the vertical movement of the rod 51a into horizontal movement using a link member or the like, and a pressing part 53 that moves horizontally by the motion direction conversion mechanism 52. The pressing part 53 pushes the opening / closing body 10 and presses it against the receiving part 21 in the guide rail 20.

[0027] As shown in Figure 2, the deflection suppression device 60 includes a movable column 61 that extends vertically in an elongated shape, and a guide mechanism (not shown) that suspends the movable column 61 and moves it in the width direction of the opening / closing body. The movable column 61 moves from the end side to the center side in the width direction of the opening / closing body and presses against the indoor side of the opening / closing body 10, thereby suppressing the deflection of the opening / closing body 10.

[0028] Next, we will describe the specific configuration of each panel 11 to 13 that make up the opening / closing body 10. (Intermediate panel) First, we will describe an example of the specific structure of the intermediate panel 11. Figure 5 is a schematic vertical cross-sectional view showing an example of an intermediate panel constituting the opening and closing body of the opening and closing device according to the present invention. Figure 6 is a schematic vertical cross-sectional view showing the intermediate panel in a disassembled state with each functional part removed. Figure 7 is a schematic vertical cross-sectional view showing an enlarged view of the upper part of the intermediate panel (with the intermediate water-stopping member removed). Figure 8 is a schematic vertical cross-sectional view showing an enlarged view of the lower part of the intermediate panel.

[0029] The intermediate panel 11 is integrally molded from, for example, an aluminum extruded profile, and as shown in Figure 5, an outdoor side wall portion 11a facing the outside and an indoor side wall portion 11b facing the inside are arranged opposite each other with a predetermined distance between them, and a plurality of partition walls 11p and the upper and lower end walls are arranged between the outdoor side wall portion 11a and the indoor side wall portion 11b with a predetermined distance between them in the vertical direction, thereby forming a panel having a plurality of hollow portions (cavities) S1 to S3 that extend to both ends in the width direction of the opening and closing body.

[0030] In the illustrated example, the hollow sections S1 to S3 are configured to include an upper hollow section S1 located above the intermediate panel 11, a lower hollow section S2 located below the intermediate panel 11, and a plurality of intermediate hollow sections S3 arranged in series in the vertical direction between the upper hollow section S1 and the lower hollow section S2. By forming these hollow sections S1 to S3, the intermediate panel 11 can reduce the weight of the panel while ensuring panel rigidity (resistance to water pressure), resistance to damage and deformation due to external forces, and thermal insulation and sound insulation properties.

[0031] Furthermore, the outdoor side wall portion 11a of the intermediate panel 11 includes an upper wall portion 11a1 that defines the upper hollow portion S1, a lower wall portion 11a2 that defines the lower hollow portion S2, an intermediate wall portion 11a3 that is connected between the upper wall portion 11a1 and the lower wall portion 11a2 and defines the intermediate hollow portion S3, and a rising wall portion 11a4 that is connected to the upper wall portion 11a1 and rises substantially vertically above the upper hollow portion S1.

[0032] Furthermore, as shown in Figure 6, the intermediate panel 11 is formed with a holding portion 11c for holding the held portion 71 of the intermediate waterproofing member 70 (described later), and a seal portion support portion 11d for supporting (placing) the seal portion 72 of the intermediate waterproofing member 70. Additionally, a cover member 80 that hangs downward is provided at the lower end of the indoor side wall portion 11b of the intermediate panel 11. Furthermore, the intermediate panel 11 has a positioning recess 11e formed on its upper end side and a positioning protrusion 11f formed on its lower end side.

[0033] Below, the intermediate panel 11 is divided into three parts: the upper part, the lower part, and the intermediate part, and the structure of each part will be explained in detail. Figure 7 is an enlarged vertical cross-sectional schematic diagram of the upper part of the intermediate panel (with the water-stopping member removed), and Figure 8 is an enlarged vertical cross-sectional schematic diagram of the lower part of the intermediate panel. Figure 9 is a side schematic diagram explaining the positional relationship of the vertically adjacent intermediate panels, with Figure 9(a) showing the state of each intermediate panel in a downward state, and Figure 9(b) showing the state of each intermediate panel in a vertically compressed state.

[0034] <Upper part of the middle panel> [Upper hollow part] As shown in Figure 7, the upper hollow section S1 is a hollow section (cavity) located at the uppermost part of the intermediate panel 11, and is defined by the upper wall portion 11a1 of the outdoor side wall section 11a, the first upper wall section 11g, the inclined upper wall section 11h, the second upper wall section 11i, the first vertical wall section 11j, the third upper wall section 11k, the second vertical wall section 11m, the fourth upper wall section 11n, a part of the indoor side wall section 11b, and the uppermost partition wall 11p.

[0035] The first upper wall portion 11g has one end edge connected to the upper position of the upper side wall portion 11a1 in a substantially perpendicular manner, and is formed as a horizontal wall extending substantially horizontally toward the indoor side wall portion 11b. The inclined upper wall portion 11h has one end edge connected to the other end edge of the first upper wall portion 11g, and is formed as an inclined wall that extends upward toward the indoor side wall portion 11b. The second upper wall portion 11i has one end edge connected to the other end edge of the inclined upper wall portion 11h, and is formed as a horizontal wall extending substantially horizontally toward the indoor side wall portion 11b.

[0036] The first vertical wall portion 11j has one end edge connected to the lower part of the approximate center of the second upper wall portion 11i, and is formed as a vertical wall that extends approximately vertically downward. The third upper wall section 11k has one end edge connected to the lower end edge of the first vertical wall section 11j, and is formed as a horizontal wall extending substantially horizontally toward the indoor side wall section 11b. The second vertical wall section 11m is formed as a vertical wall that extends substantially vertically downward, with one end edge connected to the other end edge of the third upper wall section 11k. The fourth upper wall section 11n is formed as a horizontal wall, with one end connected to the lower end of the second vertical wall section 11m, and extending substantially horizontally toward the indoor side wall section 11b, with the other end connected to the upper end of the indoor side wall section 11b.

[0037] The uppermost partition wall 11p is formed as a horizontal wall extending substantially horizontally, with one end connected to the outdoor side wall portion 11a and the other end connected to the indoor side wall portion 11b. Furthermore, between the outdoor side wall 11a and the indoor side wall 11b, multiple partition walls 11p similar to the uppermost partition wall 11p are provided at predetermined intervals in the vertical direction.

[0038] [Holding part] A holding portion 11c is formed in the upper part of the intermediate panel 11. The holding portion 11c is the part that holds the held portion 71 of the intermediate waterproofing member 70 and is provided adjacent to the opening / closing body thickness direction of the upper hollow portion S1. Specifically, this holding portion 11c is composed of a part of the other end side of the second upper wall portion 11i, the first vertical wall portion 11j, and the third upper wall portion 11k, and is formed in a roughly U-shape in side view, opening to the indoor side wall portion 11b side (right side in the left-right direction of Figure 7) in the opening / closing body thickness direction, so as to receive the held portion 71 of the intermediate waterproofing member 70.

[0039] Furthermore, the retaining portion 11c has upper and lower locking pieces 11t and 11u formed at its open end. Specifically, the upper locking piece 11t is formed on the edge (tip edge) of the second upper wall portion 11i so as to protrude downward, and the lower locking piece 11u is formed on the edge (tip edge) of the third upper wall portion 11k so as to protrude upward.

[0040] These upper locking pieces 11t and lower locking pieces 11u protrude upward and downward, respectively, so that even if the intermediate water-stopping member 70 held by the holding part 11c is pulled outward, they lock onto the respective protruding parts 71b of the held part 71, thereby preventing the intermediate water-stopping member 70 from coming out of the holding part 11c.

[0041] The upper locking piece 11t and the lower locking piece 11u can be configured as a single locking piece that extends from one end to the other in the lateral width direction of the opening / closing body of the intermediate panel 11, or as a plurality of locking pieces that are spaced apart at predetermined intervals from one end to the other in the lateral width direction of the opening / closing body of the intermediate panel 11.

[0042] [Seal support section] A seal support portion 11d is formed in the upper part of the intermediate panel 11. The seal support portion 11d is provided adjacent to the upper hollow portion S1 in the thickness direction of the opening / closing body. Specifically, this seal support portion 11d is composed of a second vertical wall portion 11m and a fourth upper wall portion 11n, and functions as a support portion that supports the lower part of the seal portion 72 of the intermediate water-stopping member 70.

[0043] [Rising wall section] The outdoor side wall portion 11a of the intermediate panel 11 has a rising wall portion 11a4 that is connected to the upper side wall portion 11a1 and rises substantially vertically above the upper hollow portion S1. The outer surface of this rising wall portion 11a4 is formed to be flush in the vertical direction with the outer surfaces of the upper side wall portion 11a1 and the intermediate wall portion 11a3.

[0044] As shown in Figure 9, the rising wall portion 11a4 is configured to overlap the lower wall portion 11a2 of the upper intermediate panel 11. This configuration ensures that when the opening / closing body 10 is closed, the gap C (see Figure 9(a)) between the upper and lower adjacent intermediate panels 11 is covered from the outside. Therefore, it is possible to prevent fingers from getting caught in the gaps between the upper and lower adjacent panels during the opening and closing operation of the opening / closing body 10.

[0045] Furthermore, as shown in Figure 8, the lower wall portion 11a2 of the outdoor side wall portion 11a is formed such that its outer surface has a step (recess) that is inward in the thickness direction of the opening / closing body compared to the outer surface of the intermediate wall portion 11a3. Specifically, the position of the outer surface of the lower wall portion 11a2 is configured to form a step that is recessed by approximately the same dimension as the thickness of the rising wall portion 11a4 of the outdoor side wall portion 11a, and the rising wall portion 11a4 of the lower intermediate panel 11 overlaps the lower wall portion 11a2 of the upper intermediate panel 11.

[0046] Furthermore, as shown in Figure 9(a), when the opening / closing body 10 is opened or closed (raised or lowered), the upper and lower adjacent intermediate panels 11 are separated (spaced apart) from each other, with the lower end of the upper intermediate panel 11 and the upper end of the lower intermediate panel 11 separated. In other words, a predetermined gap C exists between the upper intermediate panel 11 and the lower intermediate panel 11 of the opening / closing body 10 while they are suspended by the panel connecting chain 14 (see Figure 2).

[0047] Furthermore, as shown in Figure 9(b), when the opening is closed by the opening / closing body 10 (when the opening / closing body 10 is compressed vertically by the vertical pressing mechanism 40), the lower end surface of the upper intermediate panel 11 is pressed against the intermediate watertight member 70 on the lower intermediate panel 11 side, resulting in a watertight state.

[0048] [Positioning recess] As shown in Figure 7, a positioning recess 11e is formed in the upper portion of the intermediate panel 11. The positioning recess 11e is provided adjacent to the upper hollow portion S1. Specifically, this positioning recess 11e is composed of the lower portion of the rising wall portion 11a4, the first upper wall portion 11g, and the inclined upper wall portion 11h, and when water is stopped, it fits with the positioning protrusion 11f of the intermediate panel 11 located above it to position the panels adjacent to each other above and below (see Figure 9(b)).

[0049] [Intermediate water-stopping component] The intermediate watertight member 70 is made of an elastic material such as rubber or elastomer resin, and consists of a long member that extends from one end to the other in the lateral width direction of the opening and closing body of the intermediate panel 11. This intermediate watertight member 70 elastically contracts when the vertical pressing mechanism 40 is operated, maintaining watertightness between the upper panel 12 and the intermediate panel 11, between each intermediate panel 11, and between the intermediate panel 11 and the lower panel 13.

[0050] As shown in Figures 6 and 7, the intermediate water-stopping member 70 comprises a held portion 71 and a sealing portion 72, and these held portion 71 and sealing portion 72 are integrally formed.

[0051] The retained portion 71 is inserted into and held by a retaining portion 11c formed on the upper part of the intermediate panel 11, and has a main body portion 71a and a plurality of protruding portions 71b that protrude from the main body portion 71a. This retained portion 71 is made of an elastic material with a hardness higher than that of the elastic material constituting the sealing portion 72, for example.

[0052] The main body portion 71a is formed in a substantially rectangular shape when viewed from the direction in which the intermediate water-stopping member 70 extends. A through hole 71c is formed in this main body portion 71a, extending in the direction in which the intermediate water-stopping member 70 extends. In this embodiment, the through-hole 71c is formed in an elongated shape when viewed from the extending direction and communicates with both ends in the extending direction. This through-hole 71c allows the main body portion 71a to be easily elastically deformed, thus enabling smooth replacement of the intermediate water-stopping member 70.

[0053] The protruding portion 71b is formed to be inclined toward the sealing portion 72 in the thickness direction (up and down direction in Figure 7) of the intermediate water-stopping member 70. This protruding portion 71b is configured to elastically contact and hold the retained portion 71 with the second upper wall portion 11i and the third upper wall portion 11k of the retaining portion 11c when the retained portion 71 is inserted into the retaining portion 11c. In the illustrated example, two protrusions 71b are arranged above and below the main body 71a, but the number of protrusions can be set arbitrarily.

[0054] The seal portion 72 is formed in a substantially rectangular shape when viewed from the extending direction of the intermediate water-stopping member 70, and is made of an elastic material with a hardness lower than that of the elastic material constituting the held portion 71 (i.e., a soft elastic material). With the held portion 71 held by the holding portion 11c, the seal portion 72 is supported (placed) on the seal portion support portion 11d (second vertical wall portion 11m, fourth upper wall portion 11n) of the intermediate panel 11, with a part of its upper side protruding above the upper surface of the second upper wall portion 11i of the intermediate panel 11.

[0055] As shown in Figure 5, the vertical height H1 of the seal portion 72 is configured to protrude by a predetermined height H3 from the height H2 from the upper surface of the fourth upper wall portion 11n to the upper surface of the second upper wall portion 11i (H1 = H2 + H3), and this protruding height H3 portion becomes a crushing allowance that is pressed and crushed by the intermediate panel 11 located above it.

[0056] As a result, when the opening / closing body 10 is closed, the seal portion 72 installed on the lower intermediate panel 11 is pressed against the lower end surface of the upper intermediate panel 11 (or the lower end surface of the upper panel 12), and is compressed and elastically deformed, creating a tight seal between each intermediate panel 11 (or between the intermediate panel 11 and the upper panel 12) to prevent water leakage.

[0057] <Lower part of the intermediate panel> [Lower hollow part] As shown in Figure 8, the lower hollow section S2 is a hollow section (cavity) located at the very bottom of the intermediate panel 11, and is defined by the lower wall portion 11a2 of the outdoor side wall section 11a, the first lower wall section 11q, the inclined lower wall section 11r, the second lower wall section 11s, a part of the indoor side wall section 11b, and the lowest partition wall 11p.

[0058] The first lower wall portion 11q has one end edge connected to the lower end position of the lower side wall portion 11a2 in a substantially perpendicular manner, and is formed as a horizontal wall that extends substantially horizontally toward the indoor side wall portion 11b. The inclined lower wall portion 11r has one end edge connected to the other end edge of the first lower wall portion 11q, and is formed as an inclined wall that extends upward toward the indoor side wall portion 11b. The second lower wall portion 11s is formed as a horizontal wall, with one end edge connected to the other end edge of the inclined lower wall portion 11r, and extending substantially horizontally toward the indoor side wall portion 11b, with the other end edge connected to the lower end edge of the indoor side wall portion 11b.

[0059] [Positioning protrusion] A positioning projection 11f is formed on the lower part of the intermediate panel 11. Specifically, this positioning projection 11f is composed of the lower part of the lower wall portion 11a2, the first lower wall portion 11q, and the inclined lower wall portion 11r, and when water is stopped, it fits into the positioning recess 11e of the intermediate panel 11 located below it, thereby positioning the adjacent panels above and below it (see Figure 9(b)).

[0060] [Cover component] A cover member 80, which is roughly rectangular in shape when viewed from the front, is provided on the lower end of the indoor side wall portion 11b of the intermediate panel 11. This cover member 80 is detachably attached by fastening members M, such as screws or bolts, so as to extend roughly vertically downward beyond the lower end surface of the intermediate panel 11.

[0061] As shown in Figure 6, the cover member 80 comprises, for example, a cover body 81 and a cap body 82. The cover body 81 has a mounting portion 81a and a cover portion 81b that is connected to the lower edge of the mounting portion 81a and extends downward, and is formed as a long, roughly rectangular shape in front view, extending from one end to the other in the width direction of the opening and closing body of the intermediate panel 11. This cover body 81 can be formed from, for example, a metal material similar to the material of the intermediate panel 11, or from a synthetic resin material.

[0062] The mounting portion 81a is formed in a roughly U-shape in side view, having a recess 81a1 capable of accommodating the head Mb of the fastening member M, and is a portion that is detachably attached and fixed to the lower part of the indoor side wall portion 11b of the intermediate panel 11. Specifically, the mounting portion 81a has a plurality of through holes 81a2 formed in a through-shape at predetermined intervals in the lateral width direction of the opening and closing body, and the screw portion Ma of the fastening member M is inserted through these through holes 81a2 and screwed into the screw receiving portion 11b1 formed at the lower part of the indoor side wall portion 11b, thereby being detachably attached and fixed.

[0063] As shown in Figure 9, the cover portion 81b overlaps with the upper part of the indoor side wall portion 11b of the adjacent lower intermediate panel 11, and is configured to cover the gap C between the upper and lower adjacent intermediate panels 11 and the intermediate water-stopping member 70 from the indoor side. Therefore, it is possible to prevent fingers from getting caught in the gaps between the upper and lower adjacent panels during the opening and closing operation of the opening / closing body 10.

[0064] The cap body 82 has a cap body 82a and a locking piece 82b provided on the back surface of the cap body 82a. This cap body 82 can be formed from, for example, a metal material similar to the material of the intermediate panel 11, or from a synthetic resin material.

[0065] The cap body 82a is approximately rectangular in shape when viewed from the front, so as to cover the recess 81a1 of the mounting portion 81a in the cover body 81, and is configured to be elongated, approximately the same length as the cover body 81. The head Mb of the fastening member M, which is exposed when the cover body 81 is fastened and housed within the recess 81a1 of the mounting portion 81a, is covered by this cap body 82a.

[0066] The cap body 82 is formed with upper and lower locking pieces 82b that protrude toward the recess 81a1 side of the mounting portion 81a, and is configured to be detachably attached by engaging these locking pieces 82b with an engagement recess (not shown) formed within the recess 81a1.

[0067] <Middle section of the middle panel> [Intermediate hollow section] As shown in Figure 5, the intermediate hollow section S3 consists of multiple hollow sections (cavities) arranged in a series in the vertical direction, located between the upper hollow section S1 and the lower hollow section S2, and is defined by the intermediate wall portion 11a3 of the outdoor side wall section 11a, each partition wall 11p, and the indoor side wall section 11b.

[0068] (Top panel) Next, we will describe specific structural examples of the upper panel 12. Figure 10(a) is a schematic vertical cross-sectional view showing an example of an upper panel constituting the opening and closing mechanism of the water-stopping device, and Figure 10(b) is a schematic vertical cross-sectional view showing an example of a lower panel constituting the opening and closing mechanism of the water-stopping device.

[0069] The upper panel 12, like the intermediate panel 11, is integrally molded from, for example, an aluminum extruded profile, and is configured as a panel having multiple hollow sections (cavities) S4 to S6 that extend to both ends in the width direction of the opening / closing body, by arranging multiple partition walls 12p and the upper and lower end walls between the outdoor side wall section 12a and the indoor side wall section 12b at predetermined intervals in the vertical direction.

[0070] Since this upper panel 12 is a modified version of the intermediate panel 11 described above, we will mainly explain the modified parts.

[0071] The upper panel 12 has an upper hollow section S4 located on the upper side, a lower hollow section S5 located on the lower side, and an intermediate hollow section S6 located between the upper hollow section S4 and the lower hollow section S5. A cover member 80 that hangs downward is provided at the lower end of the indoor side wall section 12b of the upper panel 12. The configuration of the intermediate hollow section S6, the lower hollow section S5, and the cover member 80 is the same as that of the intermediate hollow section S3, the lower hollow section S2, and the cover member 80 of the intermediate panel 11 described above, so a detailed explanation is omitted.

[0072] The upper hollow portion S4 of the upper panel 12 is a hollow portion defined by the upper part of the outdoor side wall portion 12a, the upper wall portion 12c, the upper part of the indoor side wall portion 12b, and the uppermost partition wall 12p. The upper wall portion 12c is formed as a horizontal wall extending substantially horizontally, with one end edge connected substantially perpendicularly to the upper end edge of the outdoor side wall portion 12a and the other end edge connected substantially perpendicularly to the upper end edge of the indoor side wall portion 12b. This upper wall portion 12c is the part that is pressed by the pressing portion 42a (see Figure 2) of the vertical pressing mechanism 40.

[0073] (Lower panel) Next, an example of the specific structure of the lower panel 13 will be described. Figure 10(b) is a schematic vertical cross-sectional view of the lower panel constituting the opening and closing body of the opening and closing device according to the present invention.

[0074] The lower panel 13, like the intermediate panel 11, is integrally molded from, for example, an aluminum extruded profile, and is configured as a panel having multiple hollow sections (cavities) S7 to S9 that extend to both ends in the width direction of the opening / closing body, by positioning multiple partition walls 13p and the upper and lower end walls between the outdoor side wall section 13a and the indoor side wall section 13b at predetermined intervals in the vertical direction.

[0075] Since this lower panel 13 is a modified version of the intermediate panel 11 described above, we will mainly explain the modified parts.

[0076] The lower panel 13 is configured to have an upper hollow section S7 located on the upper side, a lower hollow section S8 located on the lower side, and a plurality of intermediate hollow sections S9 arranged in series in the vertical direction between the upper hollow section S7 and the lower hollow section S8.

[0077] Furthermore, the outdoor side wall portion 13a of the lower panel 13 includes an upper wall portion 13a1 that defines the upper hollow portion S7, a lower wall portion 13a2 that defines the lower hollow portion S8, an intermediate wall portion 13a3 connected between the upper wall portion 13a1 and the lower wall portion 13a2, and a rising wall portion 13a4 connected to the upper wall portion 13a1 and rising substantially vertically above the upper hollow portion S7.

[0078] The configuration of the upper hollow section S7, the intermediate hollow section S9, and the rising wall section 13a4 is the same as the configuration of the upper hollow section S1, the intermediate hollow section S3, and the rising wall section 11a4 of the intermediate panel 11 described above, so a detailed explanation will be omitted.

[0079] The lower hollow section S8 of the lower panel 13 is a hollow section defined by the lower wall portion 13a2 of the outdoor side wall portion 13a, the lower wall portion 13c, the lower portion of the indoor side wall portion 13b, and the lowest partition wall 13p.

[0080] The lower wall portion 13c is configured to allow the lower water-stopping member 90 to be attached detachably. In the illustrated example, it is configured to have a holding portion 13c1 for holding the retained portion 91 of the lower water-stopping member 90, and a support portion 13c2 for supporting the back surface of the sealing portion 92 of the lower water-stopping member 90.

[0081] Specifically, the lower wall portion 13c has a pair of holding portions 13c1, 13c1 formed in a roughly U-shape in side view with an opening at the bottom, and a support portion 13c2 formed between these pair of holding portions 13c1, 13c1 so as to protrude downward.

[0082] The lower water-sealing member 90 is continuously positioned on the lower surface of the lower wall portion 13c of the lower panel 13 from one end to the other in the width direction of the opening / closing body, and is a member integrally formed from an elastic material such as rubber or elastomer resin. This lower water-sealing member 90 is pressed by the operation of the vertical pressing mechanism 40 and elastically contracts to maintain watertightness between the lower panel 13 and the immovable part G.

[0083] The lower watertight member 90 has a sealing portion 92 that contacts the immovable portion G to maintain a watertight state, and a pair of retained portions 91 that are held by each retaining portion 13c1 of the lower wall portion 13c. The retained portions 91 are formed to protrude from the back surface of the sealing portion 92 and are made of an elastic material with a hardness higher than that of the elastic material constituting the sealing portion 92.

[0084] The structure of the lower wall portion 13c of the lower panel 13 and the lower water-stopping member 90 is not limited to the above example. Any structure is acceptable in which the lower water-stopping member corresponding to the lower surface of the lower wall portion, which has any arbitrary shape, is detachably provided to the lower surface of the lower wall portion. For example, the lower water-stopping member may be bonded to the lower surface of the lower wall portion via adhesive means such as adhesive or double-sided tape.

[0085] (Method (process) for replacing intermediate water-stopping components) Next, the method (process) for replacing the intermediate waterproofing member 70 will be explained. Figures 11 to 13 are schematic diagrams illustrating an example of a method for replacing the intermediate waterproofing member with respect to the intermediate panel.

[0086] In the following explanation, of the two adjacent intermediate panels 11 located vertically, the upper intermediate panel 11 will be referred to as the upper intermediate panel 11A, and the lower intermediate panel will be referred to as the lower intermediate panel 11B (indicated by the figure numbers "11A" and "11B" in Figures 11 to 13). Furthermore, the existing intermediate water-stopping member 70 to be replaced will be referred to as intermediate water-stopping member 70A, and the new intermediate water-stopping member 70 to be replaced will be referred to as intermediate water-stopping member 70B. (These are shown as part numbers "70A" and "70B" in Figures 11 to 13.)

[0087] [Step 1 (Removal of cover component)] First, the water-stopping device 1 is activated and deactivated to maintain a predetermined gap C between the upper intermediate panel 11A and the lower intermediate panel 11B, as shown in Figure 11(a). In this state, the intermediate water-stopping member 70A of the lower intermediate panel 11B is covered on the indoor side by the cover member 80 of the upper intermediate panel 11A. In this state, the upper intermediate panel 11A and the lower intermediate panel 11B remain connected in the opening and closing direction via the panel connecting chain 14 and the support shaft 15, etc.

[0088] Next, as shown in Figure 11(b), remove the cover member 80 of the upper intermediate panel 11A. Specifically, remove the cap body 82 attached to the recess 81a1 of the mounting portion 81a of the cover body 81, and rotate the head Mb of the fastener M (screw, etc.) with a tool (screwdriver, etc.) to remove the cover body 81 from the upper intermediate panel 11A. In this state, the existing intermediate watertight member 70A attached to the lower intermediate panel 11B is exposed to the outside.

[0089] [Step 2 (Removal of existing water-stopping components)] Next, as shown in Figure 12(c), the intermediate water-stopping member 70A is removed from the lower intermediate panel 11B. Specifically, the existing intermediate water-stopping member 70A attached to the lower intermediate panel 70A is removed by pulling it out in the thickness direction of the opening / closing body. The seal portion 72 of the intermediate water-stopping member 70A is exposed on the indoor side, so it can be easily removed by pulling this seal portion 72 inwards.

[0090] If the protrusion 71b formed on the retained portion 71 of the intermediate water-stopping member 70A gets caught on the locking pieces 11t and 11u of the retaining portion 11c and becomes difficult to remove, it can be removed by prying it out with a pointed tool such as a flathead screwdriver.

[0091] [Step 3 (Installation of new water-stopping component)] Next, as shown in Figure 12(d), a new intermediate waterproofing member 70B is inserted into the lower intermediate panel 11B in the thickness direction of the opening / closing body. Specifically, the retained portion 71 of the intermediate waterproofing member 70B is inserted into the retaining portion 11c of the lower intermediate panel 11B. In this case, the protruding portion 71b formed on the main body portion 71a of the retained portion 71 should be inserted so as to extend beyond the locking pieces 11t and 11u of the retaining portion 11c.

[0092] The multiple protrusions 71b of the intermediate waterproofing member 70B elastically deform inward in the thickness direction (vertical direction in Figure 12(d)), and each elastically deformed upper and lower protrusion 71b faces the upper and lower locking pieces 11t and 11u in the insertion direction. In this state, even if the held portion 71 of the intermediate waterproofing member 70B inserted into the holding portion 11c is pulled in the direction opposite to the insertion direction, each protrusion 71b catches on the locking pieces 11t and 11u, preventing it from coming out of the holding portion 11c. This makes it possible to increase the holding force of the intermediate waterproofing member 70B on the intermediate panel 11.

[0093] In this state, the sealing portion 72 of the intermediate water-stopping member 70B is supported (placed) in contact with the second vertical wall portion 11m and the fourth upper wall portion 11n, which form the sealing portion support portion 11d of the intermediate panel 11, with a portion of its upper side protruding above the upper surface of the second upper wall portion 11i, which forms the upper end surface of the lower intermediate panel 11B. [Step 4 (Attachment of cover component)] Next, as shown in Figure 13(e), the cover member 80 is attached to the upper intermediate panel 11A. In this case, the screw portion Ma of the fastener M is inserted through the insertion hole 81a2 formed in the mounting portion 81a of the cover body 81, and the head Mb of the fastener M is rotated with a tool (such as a screwdriver) to screw it into the screw receiving portion 11b1 provided on the indoor side wall portion 11b of the upper intermediate panel 11A and fasten it. Furthermore, the cap body 82 is fitted into the recess 81a1 of the cover body 81 to complete the installation of the cover member 80 (Figure 13(f)).

[0094] In this state, the intermediate water-stopping member 70B is covered by the rising wall portion 11a4 and the cover member 80, as shown in Figure 13(f). Therefore, the intermediate water-stopping member 70B is protected from the intrusion and adhesion of dust from the outside, and is also protected from external forces, thereby ensuring that the water-stopping function of the intermediate water-stopping member 70 is adequately maintained.

[0095] Furthermore, since the gap C between the upper intermediate panel 11A and the lower intermediate panel 11B is covered by the rising wall portion 11a4 and the cover member 80, it is possible to prevent fingers from getting caught in the gap C between the upper intermediate panel 11A and the lower intermediate panel 11B when closing the opening / closing body 10, and the opening / closing body 10 can be operated safely.

[0096] The method of attaching the intermediate water-stopping member 70 to the lower panel 13 (see Figure 10(b)) is the same.

[0097] (Second embodiment) Next, other embodiments will be described. Figure 14 is a schematic vertical cross-sectional view showing another embodiment of the intermediate panel according to the present invention, with each functional part disassembled.

[0098] Note that the intermediate panel 11X shown in Figure 14 is a modified version of the intermediate panel 11 shown in Figures 5 to 8 described above. Therefore, the description will mainly focus on the modified parts, and components identical to those of the intermediate panel 11 described above will be given the same reference numerals, and redundant explanations will be omitted.

[0099] The intermediate panel 11X is constructed by changing the outdoor side wall portion 11a and cover member 80 of the intermediate panel 11 shown in Figures 5 to 8 to an outdoor side wall portion 11Xa and cover member 80X, respectively, and by adding a fire-resistant member 100 that has fire-resistant properties to cover the indoor side wall portion 11b of the intermediate panel 11X. The other structures are configured in the same way as the intermediate panel 11 shown in Figures 5 to 8.

[0100] The following describes the configuration of the outdoor side wall portion 11Xa, the cover member 80X, and the fire-resistant member 100, which differ from the configuration of the intermediate panel 11 described above.

[0101] [Outdoor side wall section 11Xa] As shown in Figure 14, the outdoor side wall portion 11Xa of the intermediate panel 11X has an upper wall portion 11Xa1 that defines the upper hollow portion S1, a lower wall portion 11Xa2 that defines the lower hollow portion S2, an intermediate wall portion 11Xa3 connected between the upper wall portion 11Xa1 and the lower wall portion 11Xa2, and a rising wall portion 11Xa4 that is connected to the upper wall portion 11Xa1 and rises substantially vertically above the upper hollow portion S1.

[0102] Compared to the intermediate panel 11 in Figure 6, this intermediate panel 11X has a larger thickness T1 in its three parts: the upper wall portion 11Xa1, the intermediate wall portion 11Xa3, and the lower wall portion 11Xa2. In other words, the intermediate panel 11X is constructed so that the thickness T1 of the three parts is greater than the thickness T2 of the indoor side wall portion 11b, thereby increasing the weight on the outdoor side wall portion 11Xa. The thickness T1 of the three parts is set to balance the weight on the indoor side wall portion 11b, to which the fire-resistant member 100 and cover member 80X are attached.

[0103] With this configuration, the weight of the outdoor side wall 11a and the indoor side wall 11b are balanced and in equilibrium, allowing the intermediate panel 11X to move up and down stably without tilting to one side. Furthermore, the thickness T3 of the rising wall portion 11Xa4 of the outer side wall portion 11Xa is configured to be the same thickness as the outdoor side wall portion 11a in Figure 6.

[0104] [Fire-resistant material 100] The fire-resistant member 100 is made of a plate-shaped member having fire-resistant properties, such as iron (steel) or stainless steel, and is attached and fixed so as to cover the indoor side wall portion 11b of the intermediate panel 11X.

[0105] The fire-resistant member 100 has, for example, a main body portion 100a that extends vertically and is formed in a roughly rectangular shape when viewed from the front, an upper side portion 100b that extends horizontally substantially perpendicular to the upper edge of the main body portion 100a, and a lower side portion 100c that extends horizontally substantially perpendicular to the lower edge of the main body portion 100a, and is formed to form a roughly U-shape when viewed from the side.

[0106] The fire-resistant member 100 can be fastened, for example, by placing the upper piece 100b and the lower piece 100c over the upper surface of the fourth upper wall portion 11n and the lower surface of the second lower wall portion 11s of the intermediate panel 11X, and then bringing the main body portion 100a into contact with the indoor side wall portion 11b, and fastening it with, for example, a fastener 200 having a waterproof function. Furthermore, the waterproof fastener 200 can be a fastener with a structure that can seal the gap formed between the rivet and the rivet hole during installation, such as a waterproof rivet with a rubber gasket incorporated into the rivet head or shaft, thereby ensuring watertightness.

[0107] [Cover component 80X] A cover member 80X, which is formed in a roughly rectangular shape when viewed from the front, is provided on the lower end of the indoor side wall portion 11b of the intermediate panel 11X. This cover member 80X is detachably attached to the indoor side wall portion 11b, which is covered with the fire-resistant member 100, by fastening members M such as screws or bolts, so as to extend roughly vertically downward beyond the lower end surface of the intermediate panel 11.

[0108] The cover member 80X is formed as a long, roughly rectangular shape in front view, extending from one end to the other in the width direction of the opening / closing body 10 of the intermediate panel 11. For example, it can be formed by bending multiple layers of fire-resistant metal plates such as iron (steel) or stainless steel. The cover member 80X may be made of any fire-resistant material and is not limited to the above example.

[0109] Similar to the cover member 80 shown in Figure 9, this cover member 80X also has the function of covering the gap C between each panel, thereby preventing fingers from getting caught in the gap C when the opening and closing mechanism 10 is opened and closed, and preventing the intermediate water-stopping member 70 from being exposed to the outside. Furthermore, since the cover member 80X is made of a fire-resistant material, it can effectively protect the intermediate water-stopping member 70 from flames and heat by covering it from the indoor side in the event of a fire.

[0110] As described above, this intermediate panel 11X has both a water-stopping function and a fire-prevention function, and can be effectively installed in fire-prevention equipment and specific fire-prevention equipment. In other words, for example, even if each panel constituting the opening / closing body 10 is integrally molded from an aluminum extruded profile, by covering the surface of each panel with a fire-resistant member 100, it is possible to configure a panel that has both a water-stopping function and a fire-prevention function.

[0111] In the example above, the structure of the intermediate panel 11X that constitutes the opening / closing body 10 was described, but the upper panel 12 and lower panel 13 that constitute the opening / closing body 10 can also be configured to be covered with fire-resistant material in the same way as the intermediate panel 11X.

[0112] (Other variations) Next, a modified example of the above embodiment will be described. Figure 15 is a schematic vertical cross-sectional view illustrating a modified example of the intermediate panel according to the present invention, where Figure 15(a) shows the lower part of the intermediate panel, Figure 15(b) shows the upper part of the intermediate panel, and Figure 15(c) shows the contact relationship between adjacent intermediate panels.

[0113] Note that the intermediate panel 11Y shown in Figure 15 is a modified version of the intermediate panel 11 shown in Figures 5 to 8 above (with changes to the upper and lower end structures). Therefore, the explanation will mainly focus on these modified parts, and components identical to those of the intermediate panel 11 above will be given the same reference numerals, omitting redundant explanations.

[0114] The intermediate panel 11Y is constructed by changing the structure of the upper end of the intermediate panel 11 shown in Figure 7 (first upper wall portion 11g, inclined upper wall portion 11h, and second upper wall portion 11i) to a horizontally extending horizontal upper wall portion 11y1, as shown in Figure 15(b). An elastic support material 110 made of an elastic material (such as rubber or closed-cell foam) having flexibility and resilience is provided on the upper surface of the horizontal upper wall portion 11y1. Furthermore, the structure of the lower end of the intermediate panel 11 shown in Figure 8 (first lower wall portion 11q, inclined lower wall portion 11r, and second lower wall portion 11s) is changed to a horizontally extending horizontal lower wall portion 11y2, as shown in Figure 15(a). The other structures are constructed in the same way as the intermediate panel 11 shown in Figures 6 to 8.

[0115] In other words, this intermediate panel 11Y is constructed by removing the positioning recess 11e that was formed on the upper end side of the intermediate panel 11 shown in Figure 7, and the positioning protrusion 11f that was formed on the lower end side shown in Figure 8. As shown in Figure 15(b), the upper end of the intermediate panel 11Y is configured as a horizontal upper wall portion 11y1 extending horizontally, and as shown in Figure 15(a), the lower end of the intermediate panel 11Y is modified to a horizontal lower wall portion 11y2 extending horizontally, thus simplifying the structure.

[0116] Furthermore, as shown in Figure 15(b), an elastic support member 110, which is roughly rectangular in side view, is arranged on the upper surface of the horizontal upper wall portion 11y1. This elastic support member 110 can be configured as a single elastic support member that extends continuously from one end to the other in the lateral width direction of the opening and closing body of the intermediate panel 11Y, or as a plurality of elastic support members provided at predetermined intervals from one end to the other in the lateral width direction of the opening and closing body of the intermediate panel 11Y.

[0117] The elastic support member 110 is set, for example, so that the height of its upper surface is approximately the same as the height of the upper part of the sealing portion 72 of the intermediate water-stopping member 70. Furthermore, the elastic support member 110 is preferably positioned closer to the outdoor side wall portion 11a.

[0118] By arranging such an elastic support member 110 on the upper surface of the horizontal upper wall portion 11y1 (preferably closer to the outdoor side wall portion 11a), for example, when closing the opening / closing body 10, if there is a gap between the upper and lower adjacent intermediate panels 11Y, and as shown in Figure 15(c), the upper intermediate panel 11Y descends and presses against the upper surface of the sealing portion 72 of the lower intermediate water-stopping member 70, the lower end surface of the upper intermediate panel 11Y (the lower surface of the horizontal lower wall portion 11y2) will descend and come into contact with the elastic support member 110 and the sealing portion 72 of the intermediate water-stopping member 70 almost simultaneously, so that the opening / closing body 10 can be closed stably. Furthermore, this elastic support material 110 is set to be approximately the same as, or lower than, the seal 72 of the intermediate watertight joint 70.

[0119] In other words, if the elastic support member 110 is not provided, when the opening / closing body 10 is closed, the lower end surface of the upper intermediate panel 11Y (the lower surface of the horizontal lower wall portion 11y2) will come into contact with the sealing portion 72 of the intermediate water-stopping member 70, which is located closer to the indoor side wall portion 11b, and will descend, which may cause the intermediate panel 11 to tilt as it descends. However, by placing the elastic support member 110 on the upper end surface of the intermediate panel 11Y (the upper surface of the horizontal upper wall portion 11y1), the lower end surface of the descending intermediate panel 11Y (the lower surface of the horizontal lower wall portion 11y2) comes into contact with the elastic support member 110 and the sealing portion 72 of the intermediate water-stopping member 70 almost simultaneously as it descends, so that the intermediate panel 11 can descend stably without tilting.

[0120] Furthermore, the present invention is not limited to the specific configurations described above, and can be modified as appropriate without altering the essence of the invention.

[0121] For example, in the above embodiment, the intermediate panels 11, 11X, and 11Y are provided with a rising wall portion 11a4, a holding portion 11c, a seal portion support portion 11d, and a positioning recess 11e at their upper ends, and a cover member 80 and a positioning projection 11f at their lower ends. However, in the reverse arrangement, the cover member 80 and positioning projection 11f may be provided at their upper ends, and the rising wall portion 11a4 (in this case, a downward wall portion), a holding portion 11c, a seal portion support portion 11d, and a positioning recess 11e may be provided at their lower ends.

[0122] <Summary> As described above, the above embodiment discloses the following invention.
