[0008] Next, an embodiment of the present invention will be described in detail with reference to the drawings. In this specification, the term "thickness direction of the opening / closing body" means the thickness direction of the opening / closing body in the closed state. The "width direction of the opening / closing body" means a direction that is substantially perpendicular to the opening / closing direction of the opening / closing body, and is not a direction that is the thickness direction of the opening / closing body. The "opening / closing direction of the opening / closing body" means the direction in which the opening / closing body slides to partition or open a space. The "outer side in the width direction of the opening / closing body" means the side in the direction toward the outside of the opening / closing body along the width direction of the opening / closing body. For example, if the guide rail on the right side is used as the reference, the outer side in the width direction of the opening / closing body is the right side. Additionally, the "inner side in the width direction of the opening / closing body" refers to the direction toward the inside of the opening / closing body along the width direction of the opening / closing body. For example, if the guide rail on the right side is used as the reference, the inner side in the width direction of the opening / closing body is the left side.

[0009] 1 to 3 show an example of a watertight device equipped with a watertight member according to the present invention. This water stop device 1 comprises an opening / closing body 10 that closes by dividing a space and abuts against a fixed surface G to fully close, left and right guide rails 20, 20 that surround both widthwise ends of the opening / closing body 10 and guide it in the opening and closing direction, an opening / closing body storage section 30 that stores and extends the opening / closing body 10 on the upper side, a closing direction pressing device 40 that abuts against the pressed portion 10a at the upper end of the opening / closing body 10 in the fully closed state from the opening direction side and presses the opening / closing body 10 in the closing direction, and a deflection suppression device 60 that suppresses the opening / closing body 10 in the fully closed state from bending toward the indoor side due to water pressure, and a thickness direction pressing device 50 and a watertight member 80 are provided within each guide rail 20. This water stop device 1 is installed so that an opening in the frame of a building or the like is opened and closed by an opening / closing body 10, and functions as a water stop panel shutter device.

[0010] The opening / closing body 10 includes a plurality of panels 11, 12 and a panel connecting chain 14 connected to these panels 11, 12 (see FIGS. 1 to 3). Of the multiple panels 11, 12, the panel 12 closest to the opening direction has a smaller dimension in the opening / closing direction than the other panels 11.

[0011] The panel 11 is a rectangular plate-like member in a front view that is long in the width direction of the opening / closing body. The panel 11 is formed by pultrusion or extrusion molding of a metal material, and has a cavity partitioned into upper and lower parts. The lower end of the panel 11 projects in a generally V-shaped vertical cross section over the entire length in the width direction of the opening / closing body, and a seal portion 16 is integrally provided on the projecting outer surface.

[0012] The seal portion 16 is made of an elastic material such as rubber or elastomer resin and has a V-shaped cross section along the lower end of the panel 11, and is joined to the lower end of the panel 11 over the entire length in the width direction of the opening / closing body.

[0013] Further, at the upper end of the panel 11, a recess 11a having a generally V-groove shape in vertical cross section is formed over the entire length in the width direction of the opening / closing body so as to fit into the seal portion 16. Support shafts 13 are provided on the upper side of the panel 11 so as to protrude from both ends of the opening / closing body in the width direction.

[0014] The uppermost panel 12 has a rectangular shape when viewed from the front, extending in an elongated manner in the width direction of the opening / closing body, and is smaller in height than the panel 11. The panel 12, similar to the panel 11, is formed by pultrusion or extrusion molding of a metal material, and has a cavity that is continuous in the width direction of the opening / closing body. Similar to the panel 11, the lower and upper end sides of this panel 12 are provided with a seal portion 16 and a support shaft portion 13. The upper end of the panel 12 is also provided with a recess 12a that continues across the width of the opening / closing body.

[0015] The support shaft portions 13 protrude outward in the width direction of the opening / closing body from both ends of each of the panels 11, 12 in the width direction (left and right direction in FIG. 1). The support shaft portion 13 is configured to rotatably support a roller on the tip side of a shaft-shaped member inserted through a panel connecting chain 14 .

[0016] The panel connecting chain 14 is a so-called roller chain used for power transmission etc., and has support shaft portions 13 rotatably inserted therethrough at predetermined intervals in the length direction thereof. This panel connecting chain 14 connects all of the panels 11 and 12 in the vertical direction via support shaft portions 13, and its upper end side is hung on a sprocket 31 of the opening / closing body storage portion 30.

[0017] Furthermore, a guide shaft portion 15 is provided on the lower end side of each panel 11 closer to the indoor side (see FIG. 2). The guide shaft portion 15 rotatably supports a roller on the tip side of a shaft-shaped member protruding from the widthwise end of each panel 11. When each panel 11 is stored in the opening / closing body storage portion 30, this guide shaft portion 15 engages with and is guided by a guide member 34 of the opening / closing body storage portion 30, thereby suppressing vibration in the opening / closing body thickness direction.

[0018] The guide rail 20 is formed to have a concave or U-shaped cross section so as to surround the widthwise end of the opening / closing body 10 in the closed state (see FIG. 3). The guide rail 20 is formed in an elongated shape extending from the stationary surface G to the opening / closing body storage section 30. Within the guide rail 20, there is provided a thickness-wise pressing device 50 that presses the opening / closing body 10 in the closed state from the outdoor side to the indoor side, and a watertight member 80 that receives the opening / closing body 10 pressed by this thickness-wise pressing device 50 from the indoor side.

[0019] The thickness direction pressing device 50 is a device that presses the opening / closing body 10 in the fully closed state toward the indoor side in the vertical direction. This thickness direction pressing device 50 is configured, for example, with a contact member that contacts the outdoor side of the opening / closing body 10, a link mechanism that moves the contact member in parallel toward the indoor side, and a drive source such as a motor.

[0020] The opening / closing body storage section 30 is fixed to a wall surface of a building or the like on which the water stop device 1 is to be installed. As shown in Figure 2, this opening / closing body storage section 30 is equipped with a sprocket 31 around which the panel connecting chain 14 is wound, a drive mechanism 32 (for example, consisting of a rotary motor, chain, sprocket, etc.) that electrically rotates the sprocket 31 in both directions, a storage rail 33 that suspends the panels 11 and 12 via the support shaft section 13 and guides them in the forward and backward directions, and a guide member 34 that guides the guide shaft section 15 on the lower end side of the panel 11 in the horizontal direction. In this opening / closing body storage section 30, the drive mechanism 32 rotates the sprocket 31 in one direction, thereby sequentially extending the stored panels 11, 12 to the outdoor side and performing a closing operation downward. In addition, the opening / closing body storage section 30 also rotates the sprocket 31 in the opposite direction using the drive mechanism 32, thereby performing an opening operation on the closed panels 11, 12, and storing them on the indoor side at the upper side.

[0021] The closing direction pressing device 40 is composed of a plurality of pressing units 40a spaced apart in the width direction of the opening / closing body (see FIG. 1). Each pressing unit 40a is configured to press the upper end of the opening / closing body 10 downward in the fully closed state by means of a piston-cylinder mechanism, a driving device, or the like.

[0022] The deflection suppression device 60 also includes a movable column 61 that extends vertically in a long shape, and a guide mechanism 62 that suspends the movable column 61 and moves it in the width direction of the opening / closing body, and moves the movable column 61 from the end side to the center side in the width direction of the opening / closing body and presses it against the indoor side of the opening / closing body 10, suppressing deflection of the opening / closing body 10.

[0023] The watertight member 80 also includes an elastic watertight portion 81 having a pressure-contact surface 81a on one side that is pressed against the opening / closing body 10 and a base end surface 81b on the other side (the opposite side, in other words), a support piece 82 that is made of a material harder than the elastic watertight portion 81 and is integrally embedded on the base end surface side of the elastic watertight portion 81, and a holder 83 that is separate from the support piece 82 and is made of a material harder than the elastic watertight portion 81, and that partially covers the elastic watertight portion 81 and the support piece 82 from the other side in a substantially concave shape and has the pressure-contact surface 81a protruding to the one side, and the base end surface 81b of the elastic watertight portion 81 is pressed against the holder 83 around the support piece 82, and the support piece 82 is joined to the holder 83 by a fastener 84 (see Figures 4 to 8). Here, the term "separate bodies" means that the support piece 82 and the holder 83 are separate components and can be separated (divided).

[0024] The elastic watertight portion 81 is made of an elastic material such as rubber or elastomer resin, and has a generally rectangular cross section having a pressure contact surface 81a and a base end surface 81b, which is continuous in a long shape extending in the vertical direction (see FIG. 5). The elastic watertight portion 81 brings the generally flat pressure contact surface 81a into close contact with the indoor side surface of the opening-closing body 10 in the vertical direction.

[0025] A fitting recess 81c is provided on the base end surface side of the elastic watertight portion 81 over the entire length in the longitudinal direction, into which the support piece 82 is fitted so as to be embedded. The fitting recess 81c has a narrow portion 81c1 that opens so that the dimension in the width direction (horizontal direction in the illustrated example) that intersects with the longitudinal direction at the base end surface 81b is relatively small, and a wide portion 81c2 that expands in the dimension in the width direction at the rear side of the narrow portion 81c1. In other words, the fitting recess 81c is a generally concave groove that is wider on the rear side (the pressure contact surface 81a side) than on the opening side (see FIG. 5).

[0026] The support piece 82 is made of a hard material such as metal (for example, an aluminum alloy) and is formed so as to fit into the fitting recess 81c of the elastic watertight portion 81 along the longitudinal direction. This support piece 82 has a base 82a that contacts or is close to the inner wall surface 83a of the holder 83, and a flange 82b that protrudes in the width direction on one side of this base 82a (in the illustrated example, on the pressure contact surface 81a side), and is formed in an approximately convex cross section, and is continuous in an elongated shape in the vertical direction. In the base portion 82a, a groove 82c for inserting the tip end side of the fastener 84 is provided on the surface that contacts the inner wall surface 83a of the holder 83 (see FIG. 8).

[0027] The base portion 82a and the flange portion 82b are formed to fit into the narrow portion 81c1 and the wide portion 81c2 of the elastic watertight portion 81, respectively.

[0028] The groove 82c is formed with a width dimension that allows the fastener 84 to be screwed therein.

[0029] The fastener 84 is an adjustment screw that is inserted into the holder 83 described below and threaded into the groove 82c of the support piece 82. The pressure contact force of the elastic watertight portion 81 against the holder 83 changes depending on how tightly the fastener 84 (adjustment screw) is tightened.

[0030] The holder 83 is formed from a hard material such as metal (e.g., aluminum alloy, etc.), and has an inner wall surface 83a facing the elastic watertight portion 81 and the base end portion of the support piece 82, and side wall portions 83b, 83b protruding from both ends of this inner wall surface 83a and covering the side surfaces of the elastic watertight portion 81. The holder 83 has an approximately concave cross section having an inner wall surface 83a and side wall portions 83b, 83b, and extends vertically in a continuous, elongated shape.

[0031] The inner wall surface 83a of the holder 83 is provided with a support piece receiving surface 83a1 that receives the base 82a of the support piece 82, an elastic watertight portion receiving surface 83a2 that receives the base end surface 81b of the elastic watertight portion 81, and a protrusion 83a3 that partially receives and contracts the base end surface 81b at a position protruding beyond the elastic watertight portion receiving surface 83a2.

[0032] When the support piece receiving surface 83a1 comes into contact with the hard support piece 82, it restricts the amount of elastic contraction of the elastic watertight portion 81, thereby preventing the elastic watertight portion 81 from becoming worn or the like.

[0033] The elastic watertight portion receiving surface 83a2 comes into contact with a portion of the base end surface 81b of the elastic watertight portion 81 closer to the side, causing that portion to elastically contract.

[0034] The projection 83a3 partially projects from the elastic watertight portion receiving surface 83a2 and comes into contact with the base end surface 81b of the elastic watertight portion 81, thereby causing the elastic watertight portion 81 to partially contract. The protrusion 83a3 is a continuous ridge extending over the entire length of the elastic watertight portion 81 in the vertical direction.

[0035] The amount a by which the projection 83a3 protrudes from the elastic watertight portion receiving surface 83a2 is greater than the amount b by which the support piece receiving surface 83a1 protrudes (see FIG. 8). That is, the support piece receiving surface 83a1 protrudes from the elastic watertight portion receiving surface 83a2, and further, the protrusion 83a3 protrudes from the support piece receiving surface 83a1.

[0036] The side wall portion 83b partially (in the illustrated example, about half of the thickness) covers the side portion of the elastic watertight portion 81. Therefore, when the opening-closing body 10 presses the elastic watertight portion 81 and the amount of shrinkage of the elastic watertight portion 81 is excessive, the opening-closing body 10 abuts against the side wall portion 83b, preventing excessive shrinkage and settling of the elastic watertight portion 81.

[0037] In FIG. 6, reference numeral 83a4 denotes an insertion hole for inserting the threaded portion of the fastener 84 through.

[0038] The watertight member 80 having the above-described configuration is fixed by fasteners 84 with the holder 83 in contact with the inner wall surface of the guide rail 20. The fasteners 84 pass through the guide rail 20 and the holder 83 and are screwed into the support pieces 82.

[0039] Next, the characteristic functions and effects of the water stopping device 1 and the watertight member 80 configured as described above will be described in detail. To move the opening / closing body 10 to the water-stopping position, the drive mechanism 32 or the like is operated to move the multiple panels 11, 12 stored in the opening / closing body storage section 30 from the indoor side to the outdoor side, and then move them downward along the guide rail 20. The panels 11 and 12 are stacked one on top of the other on the immovable surface G in a fully closed state, with the panel 12 positioned at the top of these panels.

[0040] Next, the thickness direction pressing device 50 is operated to press the opening / closing body 10 (more specifically, the panels 11, 12) against the watertight member 80 (see FIG. 3). After that, the closing direction pressing device 40 presses the upper end of the opening / closing body 10 downward, pressing it against the fixed surface G of the lower end of the opening / closing body 10. By these pressing operations, the opening-closing body 10, which is pressed downward and moves, comes into sliding contact with the elastic watertight portion 81 of the watertight member 80. That is, the elastic watertight portion 81 receives a downward force from the opening-closing body 10. However, since the elastic watertight portion 81 is pressed against the elastic watertight portion receiving surface 83a2, the support piece receiving surface 83a1, and the protrusion 83a3 of the holder 83 in an uneven manner, it is possible to prevent this elastic watertight portion 81 from shifting downward relative to the holder 83 and compromising its watertightness.

[0041] In the water stop device A, the lower end side and both left and right ends of the opening / closing body 10, the gap between adjacent panels 11, 11 (or 12), etc. can be kept watertight.

[0042] Next, the features of the manufacturing method of the watertight member 80 will be described. The manufacturing method of the watertight member 80 includes a first step of elastically deforming the elastic watertight portion 81 to fit it onto the support piece 82 from one side in the thickness direction, a second step of fitting the elastic watertight portion 81 and the support piece 82 with the holder 83, and a third step of fixing the support piece 82 and the holder 83 with a fastener 84.

[0043] 7(a) to 7(d), in cross section, the flange portion 82b of the support piece 82 is inserted into the fitting recess 81c of the elastic watertight portion 81, and the narrow width portion 81c1 of the elastic watertight portion 81 is elastically deformed, thereby gradually moving the support piece 82 toward the back of the fitting recess 81c. These operations bring the elastic watertight portion 81 and the support piece 82 into a state where they are completely fitted together.

[0044] This first step makes it possible to smoothly perform the work of integrating the elastic watertight portion 81 and the support piece 82. In other words, if the support piece 82 is inserted into the longitudinal end of the fitting recess 81c and slid, the resistance (friction) during the sliding is large, and it takes time to completely fit the long elastic watertight portion 81 and the support piece 82 together. However, in the first step, the elastic watertight portion 81 and the support piece 82 are fitted together by utilizing the elastic deformation of the narrow width portion 81c1 of the elastic watertight portion 81, and therefore the workability is good.

[0045] 6, in the second step, the holder 83 is fitted to the integrated elastic watertight portion 81 and support piece 82 by bringing them close in the thickness direction. Alternatively, the support piece 82 is fitted to the recessed portion of the holder 83 by inserting it into the recessed portion.

[0046] 8, in the third step, a fastener 84 is inserted through the guide rail 20 and the holder 83, and this fastener 84 is screwed into the groove 82c of the support piece 82. Then, by adjusting the degree of tightening of the fastener 84, the elastic watertight portion 81 is pressed against the holder 83, and the amounts a and b of contraction are appropriately adjusted.

[0047] Therefore, according to the above manufacturing method, the watertight member 80 made up of multiple components can be easily produced, and the manufacturing workability is also good. Moreover, the elastic watertight portion 81 can be firmly fixed to the holder 83 so that it does not shift in the vertical direction, and the watertightness is also good.

[0048] <Modification> According to the above embodiment, the fastener 84 is an adjusting screw as a particularly preferred example, but another example of the fastener 84 may be a fastener such as a rivet that does not have a threaded portion on the tip side. In this case, the tip side of the fastener 84 may be fitted into the groove 82c without being screwed.

[0049] Furthermore, in the above embodiment, the watertight member 80 is applied to a water stop panel shutter, but the watertight member 80 can also be applied to a water stop device that allows a water stop plate to be attached and detached to an opening in a building, etc. In this case, for example, the watertight member 80 may be provided between the water stop plate and the left and right vertical frames that form the opening in a building, etc.

[0050] Furthermore, in a form other than the illustrated example, the watertight member 80 can also be used in fittings devices such as opening door devices, sliding door devices, folding door devices, balance door devices, window devices, etc. In this case, the watertight member 80 can be provided in a portion where watertightness is required, such as between the contact portion of the door body and the frame body.

[0051] In addition, in the above embodiment, the protrusion 83a3 of the holder 83 is a protrusion that continues in the vertical direction (up and down in the illustrated example), but other examples of this protrusion 83a3 include a protrusion that continues in the horizontal direction, or a convex portion that protrudes partially in the vertical and horizontal directions.

[0052] Furthermore, in the above embodiment, as a particularly preferred example, the holder 83 is configured to have side wall portions 83b, 83b, but as an example other than the illustrated example, it is also possible to configure the holder 83 so that the side wall portions 83b, 83b are omitted.

[0053] Furthermore, the present invention is not limited to the specific configurations described above, and can be modified as appropriate within the scope of the present invention.
