Description

The present invention relates to a storage structure for reinforcing middle columns in a door device. In the embodiment described later, the door device is a waterproof door.

In recent years, guerrilla heavy rain due to abnormal weather has frequently occurred, and rainwater inundation accidents have occurred in subway premises and building basements in urban areas. There are cases where it is desired to prevent external water from entering the building by installing it at the entrance of a building in an emergency. In addition, not only during guerrilla heavy rain, there are cases where it is desired to prevent the inundation by closing the building opening in a water-stopped state.

The present applicant has proposed a waterproof door that can maintain a water stop function even when a large water pressure acts on a door body in a water stop state (Patent Document 1). Patent Document 1 has a first surface portion on the first side (outdoor side) and a second surface portion on the second side (indoor side), and the building opening is closed and partitioned into the first side and the second side. A door in a fully closed state, comprising: a door body; and a horizontal compression means that contacts the first surface portion of the door body in a fully closed state and presses the door body in a horizontal direction from the first side to the second side. On the second side of the body, a waterproof door is disclosed in which a reinforcing middle pillar is installed in close proximity to or in contact with the second surface portion of the door body. When water pressure acts on the first surface portion of the door body in a water-stopped state, the second surface portion of the door body is abutted and supported by the middle pillar, preventing excessive deformation of the door body in the water-stopped state. Water condition is maintained.

Japanese Patent Application Laid-Open No. H10-228667 discloses a single pillar with one specification and a two pillars with two specifications. When one reinforced middle column is moved from the installation position to the storage position for storage, the middle column is brought into contact with a stopper provided on one side of the building opening so as to be positioned. When storing two reinforced middle pillars from the installation position to the stowed position, each reinforced middle pillar is positioned by contacting the middle pillar with stoppers provided on both sides of the building opening. It comes to stop.

The number of reinforcing middle columns installed can be determined as appropriate according to the opening width dimension or the like, but there are cases where three or more reinforcing middle columns are provided to cope with a larger assumed water pressure. Here, in the three pillars with three specifications, one middle pillar may be stored on one side of the building opening and two middle pillars may be housed on the other side. In this case, the problem is how to position the two middle pillars and store them on the same side. Further, when two reinforcing middle columns are installed, the same applies to the case where the two reinforcing middle columns are housed on the same side.

[A] Basic structure of panel shutter constituting waterproof door The basic structure of the waterproof door according to the present embodiment includes a panel shutter. As shown in FIGS. 1 to 4, the panel shutter is provided with a shutter curtain composed of a plurality of panels 1 and both ends of the building opening in the width direction. And left and right guide bodies 2 for guiding. In FIG. 4, the left side of the panel 1, that is, the shutter curtain is the outdoor side, and the right side is the indoor side. In FIG. 5, the upper side of the panel 1 is the outdoor side, and the lower side is the indoor side.

The panel 1 is a horizontal rectangular element having a predetermined thickness and extending in the opening width direction. When the opening is fully closed, one surface portion faces the outdoor side (outdoor side surface portion 100) and the other surface portion is the chamber. Facing inside (inner side surface portion 101). As shown in FIGS. 5 and 11 (one end portion in the width direction of the panel 1 is shown, and the other end portion has the same configuration), guide rollers 11 are provided at both end portions in the width direction of each panel 1. The provided support shaft 10 is projected, and each panel 1 is connected to the chain 3 (see FIG. 11) via the support shaft 10 and suspended to form a shutter curtain. Although the chain is omitted in FIG. 4 and the like, it should be noted that in the panel shutter, a configuration in which each panel is suspended by the chain is well known to those skilled in the art.

The upper end of the guide part 2 extends into the storage space above the opening, and includes an upper extension part 2 ′ (see FIG. 4) that guides the guide rollers 11 at both ends in the width direction of the panel 1. The upper extending portion 2 ′ is configured to be able to contact the guide roller 11 from both the outdoor side and the indoor side. In the storage space above the opening, there is provided a sprocket 4 that is positioned substantially at the upper end of the upper extension 2 ′ and for winding the chain 3, and the sprocket 4 is rotated by the opening / closing machine M to By lifting or feeding, the panel 1 is raised or lowered to open and close the building opening.

The storage space of the panel 1 above the opening extends from the upper portion of the opening toward the indoor side. The storage space extends in a gently downwardly inclined manner from the front to the rear (from the shutter core C to the indoor side). A storage rail 5 is provided. The panel 1 that has moved into the storage space due to the lifting of the chain 3 is relayed to the storage rail 5 via the sprocket 4, and the panel 1 is sequentially sent to the rear of the storage space while the guide roller 11 is guided by the storage rail 5. And held and housed in a state where they hang down in parallel with each other.

In the panel shutter configured in this manner, when the sprocket 4 is rotationally driven in the chain lifting direction by the opening / closing machine M in the fully closed state of the opening, each panel 1 in the fully closed vertical position causes the chain 3 to rise. Accordingly, the both ends in the width direction rise while being guided by the vertical guide body 2, and are sequentially received from the upper panel 1 by the storage rail 5 extending in the lateral direction from the upper extending portion 2 'of the guide body 2. Passed and stored in parallel in the storage space, the opening is opened.

When the sprocket 4 is rotationally driven in the chain feed-out direction by the opening / closing machine M in the fully open state of the opening, the panels 1 stored in parallel are sequentially stored in space while the guide rollers 11 at both ends in the width direction are guided by the storage rails 5. When pulled out from the rear side to the front sprocket 4 side and passes through the sprocket 4, it descends while being vertically guided to each other in the height direction while being guided by the guide body 2, and the opening is closed.

When the shutter curtain is lowered, the upper end of the lower panel and the lower end of the upper panel are separated from each other in any two adjacent panels 1 (FIG. 6C, FIG. 7, FIG. 8, etc.). reference). When the shutter curtain descends, the lower end of the lowermost panel 1 is landed, and then the shutter curtain continues to descend for a predetermined distance, so that the upper end of the lower panel in any two adjacent panels 1 above and below And the lower end of the upper panel come into contact with each other to be fully closed (see FIGS. 6B and 9). Furthermore, as will be described in detail later, the shutter curtain in the fully closed state is compressed in the vertical direction to be in a vertically compressed state (see FIGS. 6A and 10).

A photoelectric sensor 6 illustrated as an obstacle detection unit is provided below the opening at a predetermined height from the floor surface. In the illustrated embodiment, four photoelectric sensors 6 are provided on the outdoor side and the indoor side, respectively, with a height position of 150 mm and a height position of 500 mm from the floor surface. In the present embodiment, when an obstacle is detected while the shutter curtain is being lowered, the shutter curtain that is being lowered is raised for 1.5 seconds after being stopped for 1 second. The specific configuration of the obstacle detection means and the operation procedure after the obstacle detection are not limited to these.

Although the basic configuration of the panel shutter has been described with reference to the drawings, the basic configuration of the panel shutter is known to those skilled in the art, and further detailed description is omitted. Further, regarding the panel shutter, several modifications and improvements are known to those skilled in the art, and the configuration of the panel shutter that can be applied to the waterproof door according to the present invention is not limited to the illustrated embodiment. Please note that.

[B] Water-stopping structure of waterproof door [B-1] Water-stopping structure of panel With reference to FIGS. 7 to 11, the water-stopping structure between adjacent panels will be described. As shown in FIGS. 7 and 8, the panel 1 is integrally formed from an extruded aluminum material, and includes an outdoor side surface portion 100, an indoor side surface portion 101, an upper end surface 102, and a lower end surface 103. The lower end surface 103 of the panel 1 includes an upward curved concave surface 1030, an outdoor horizontal surface 1031 and an indoor horizontal surface 1032 respectively located on the outdoor side and indoor side of the concave surface 1030 in a side view. The upper end surface 102 of the panel 1 includes a convex surface 1020 that is curved upward, and an outdoor fitting groove 1021 and an indoor fitting groove 1022 that are located on the outdoor side and indoor side of the convex surface 1020, respectively.

A watertight rubber 12 (see FIGS. 6 to 10) is provided on the upper end surface 102 of each panel 1 except the uppermost panel 1 over the entire width direction. As shown in FIGS. 7 and 8, the watertight rubber 12 includes, as viewed from the side, an upward curved portion 120, an outdoor horizontal portion 121 and an indoor horizontal portion 122 positioned on the outdoor side and indoor side of the upward curved portion 120, respectively. And the fitting protrusions 123 and 124 integrally formed on the lower surface 122 of the outdoor side horizontal portion 121 and the indoor side horizontal portion 122, respectively. The watertight rubber 12 is fixed to the upper end surface 102 of the panel 1 by fitting the fitting protrusions 123 and 124 into the outdoor fitting groove 1021 and the indoor fitting groove 1022 of the upper end surface 102 of the panel 1, respectively. The

When the shutter curtain is in the vertical compression state, the outdoor horizontal surface 1031 and the indoor horizontal surface 1032 of the lower end 103 of the panel 1 are pressed against the outdoor horizontal portion 121 and the indoor horizontal portion 122 of the watertight rubber 12 of the panel 1, respectively. 10 (see FIG. 10), the outdoor horizontal portion 121 of the watertight rubber 12 of the panel 1 and the upper portion of the indoor horizontal portion 122 (the portions indicated by hatching in FIGS. The degree of adhesion at the time of pressure contact is increased by reducing the hardness of the rubber at the slightly swelled portion). A plurality of protrusions 1200 are formed on the upward curved portion 120 of the watertight rubber 12 over the entire length. In the fully closed state (non-vertical compression state), the protrusion 1200 is slightly separated from the upward curved concave surface 1030 of the lower end surface 103 of the upper panel 1 (see FIG. 9). In the vertically compressed state, the upward curved concave surface 1030 of the lower end surface 103 of the upper panel 1 and the upward curved portion 120 of the watertight rubber 12 fixed to the upper end surface 102 of the lower panel 1 are interposed via the protrusion 1200. Since it contacts linearly (refer FIG. 10), the water stop effect improves compared with the case where surfaces contact. In the illustrated embodiment, two parallel projections 1200 are shown, but the number of projections 1200 is not limited.

When the opening is fully closed, the water stop structure between the upper and lower adjacent panels is formed by pressing the lower end of the upper panel 1 of the two adjacent panels 1 and the upper end of the lower panel 1 through the watertight rubber 12. Can be obtained. A watertight rubber 13 (see FIGS. 1 to 4 and 6) is provided at the lower end of the lowermost panel 1 over the entire width direction. When the opening is fully closed, the watertight rubber 13 is pressed against the floor surface. As a result, a water stop structure at the lower end of the shutter curtain is obtained. In other words, by pressing the shutter curtain in the fully closed state vertically from the upper end toward the floor surface, a water-stopped state can be obtained between the panels 1 adjacent to each other in the vertical direction and between the lowest panel 1 and the floor surface.

The watertight rubber forming the water-stopping structure between the two adjacent panels 1 is not limited to the one provided at the upper end of the panel 1, and the entire width direction is provided at the lower end or / and the upper end of the panel 1. A watertight rubber is provided over the upper and lower sides of the upper panel 1 of the two adjacent panels 1 and the upper end of the lower panel 1 by pressing the watertight rubber through the watertight rubber when the opening is fully closed. The water stop structure between adjacent panels should just be obtained.

Next, the finger pinching prevention structure of the panel 1 and the accompanying water stop structure will be described mainly with reference to FIGS. 5 and 7 to 11. As described above, when the shutter curtain of the panel shutter is lowered, the upper end surface 102 (watertight rubber 12) of the lower panel 1 of the two adjacent panels 1 and the lower end surface 103 of the upper panel 1 are separated from each other. (See FIGS. 6C, 7, and 8). Therefore, a finger pinching prevention structure is provided on the panel 1 so that a gap is not formed on the outdoor side and the indoor side of the descending shutter curtain. This will be specifically described below.

As shown in FIGS. 7 and 8, on the upper end side of the outdoor side surface portion 100 of the lower panel 1, a rising piece (outdoor vertical) extending vertically from the outdoor side surface portion 100 beyond the upper end surface 102 of the panel 1. Piece 1000) is formed, and on the lower end side of the outdoor side surface portion 100 of the upper panel 1, an outdoor side step portion 1001 is formed by denting the outdoor side surface portion 100. 1000 overlaps the vertical surface 1002 of the outdoor step 1001 of the panel 1. The thickness of the outdoor vertical piece 1000 and the step size (depth) of the outdoor step 1001 are substantially the same. As is clear from FIGS. 7 to 10, the outdoor vertical piece 1000 and the vertical surface 1002 of the outdoor stepped portion 1001 overlap each other in the case of descent, fully closed state, and vertical compression state. There is no gap on the outdoor side between the panels 1 adjacent to each other. The outdoor vertical piece 1000 and the outdoor step 1001 are formed across the entire width of the panel 1.

On the lower end side of the indoor side surface portion 101 of the upper panel 1, a hanging piece (indoor vertical piece 1010) extending downward from the indoor side surface portion 101 beyond the lower end surface 103 of the panel 1 is formed. An indoor side step portion 1011 is formed by denting the indoor side surface portion 101 at the upper end side of the indoor side surface portion 101, and the indoor side vertical piece 1010 of the upper panel 1 is formed in the indoor side step portion 1011 of the lower panel 1. It overlaps with the vertical plane 1012. The thickness of the indoor vertical piece 1010 and the step size (depth) of the indoor step 1011 are substantially the same. As apparent from FIGS. 7 to 10, the indoor vertical piece 1010 and the vertical surface 1012 of the indoor side stepped portion 1011 overlap each other in descending, fully closed state, and vertically compressed state. A gap does not occur on the indoor side between the panels 1 adjacent to each other.

The indoor side stepped portion 1011 is formed over the entire width of the panel 1, whereas both ends in the width direction of the indoor vertical piece 1010 are cut away (see the upper diagram in FIG. 11).

The operation lever 95 is in the first position (position rotated upward) during storage and movement, and the operation lever 95 is rotated in the second position (downward) in the middle column 9 moved to the installation position. , The upper locking rod 92 protrudes upward from the upper end surface 97 of the middle column 9 through the link mechanism 96 and locks into the locking receiving hole 920, and the lower locking rod. 93 and 94 protrude downward from the lower end surface 98 of the middle column 9 and are engaged with the engagement receiving holes 930 and 940, respectively. A link mechanism for projecting the rod upward and downward by a single lever turning operation is well known to those skilled in the art, and a detailed description thereof will be omitted.

In the present embodiment, the lower end of the lower locking rod 93 is positioned slightly below the lower end of the lower locking rod 94, and is lower than the lower end surface 98 of the middle column 9 in that positional relationship. Protrusively. Specifically, the upper ends of the lower locking rods 93 and 94 are at the same level, and the length of the lower locking rod 93 is slightly longer than the length of the lower locking rod 94 ( 22 and 25). When the upper locking rod 92 and the lower locking rods 93, 94 are locked to the locking receiving holes 920, 930, 940 by the turning operation of the operation lever 95, the lower locking rod 93 is locked. With the light receiving hole 930 lightly locked, the lower locking rod 94 can be aligned and locked with the locking receiving hole 940 while finely adjusting the position of the lower end portion of the middle column 9 and smoothly A locked state can be obtained.

The middle column 9 is a long member having a rectangular shape in cross section and having a height substantially corresponding to the opening height, and as shown in FIG. 22, an upper end surface 97, a lower end surface 98, and four side surfaces. (First surface 900, second surface 901, third surface 902, fourth surface 903). In plan view, the first surface 900 and the second surface 901 facing each other are short sides, and the third surface 902 and the fourth surface 903 facing each other are long sides. In this specification, a line connecting the first surface 900 and the second surface 901 is called a major axis, and a line connecting the third surface 902 and the fourth surface 903 is called a minor axis. The middle column 9 has a first width along the major axis and a second width (<first width) along the minor axis.

The suspension position of the middle column 9, that is, the suspension shaft 910 is closer to the second surface 901 than the middle point of the first width in the major axis direction of the middle column 9. The middle column 9 is rotatable around a suspension shaft 910. As is clear from a comparison between FIG. 25 showing the installation posture and FIG. 26 showing the storage posture, in the installation posture, the first surface 900 of the middle pillar 9 is close to the indoor side surface portion 101 of the panel 1 and the storage posture. Then, the middle column 9 is in a posture rotated 180 degrees around the suspension shaft 910, and the second surface 901 of the middle column 9 is opposed to the outdoor side.

When the middle column 9 is stored or moved, the second surface 901 of the middle column 9 is closer to the indoor side surface portion 101 of the panel 1, and the first surface 900 of the middle column 9 is farther from the indoor side surface portion 101 of the panel 1. By setting it as the side, a sufficient space is formed between the second surface 901 of the middle column 9 and the indoor side surface portion 101 of the panel 1, and the contact between the middle column 9 and the panel 1 is prevented. Can be moved easily.

In the installation posture of the middle column 9, the middle column 9 moved to the installation position is rotated around the axis about the suspension shaft 910, and the first surface 900 of the middle column 9 is moved to the indoor side surface portion 101 of the panel 1. By setting the second surface 901 of the middle column 9 on the near side and the side farther from the indoor side surface portion 101 of the panel 1, the first surface 900 of the middle column 9 is brought close to and opposed to the indoor side surface portion 101 of the panel 1. In this way, when the water pressure acts on the shutter curtain that is pressed in the vertical direction and the horizontal direction and is in a water-stopped state from the outdoor side, the indoor side surface portion (the indoor side surface portion 101 of the panel 1) of the shutter curtain is Abutting against the first surface 900 of the pillar 9, the middle pillar 9 cooperates with the panel 1 in the water-stopped state, and well counters the water pressure that will act on the panel 1 in the water-stopped state.

In the present embodiment, in the non-horizontal compression state of the panel 1 in the fully closed state, the first surface 900 of the middle pillar 9 and the indoor side surface portion 101 of the panel 1 are separated by a gap G1. Furthermore, even in the horizontal compression state of the panel 1 in the fully closed state and the vertical compression state, the first surface 900 of the middle column 9 and the indoor side surface portion 101 of the panel 1 are separated by a gap G2 (<G1). The gap G1 is shown in FIG. 25, but the gap G2 is not shown. In this embodiment, the moving distance of the panel 1 to the indoor side by horizontal compression is on the order of several millimeters.

Even when the panel 1 is in the horizontal compression state (fully closed state / vertical compression state), the gap G2 is provided between the indoor side surface portion 101 of the panel 1 and the first surface 900 of the middle column 9 in the installation posture. By forming the panel 1, it is possible to prevent the panel 1 from being wrinkled due to contact between the indoor side surface portion 101 of the panel 1 and the first surface 900 of the middle column 9 in a state where water pressure does not act on the panel 1. In the horizontal compression state of the panel 1 (fully closed state / vertical compression state), a gap is formed between the indoor side surface portion 101 of the panel 1 and the first surface 900 of the middle pillar 9, so that the horizontal compression is completed. However, it is possible to move the middle column 9 in the installation posture to the storage posture without releasing the horizontal compression. Even in the horizontal compression state, when the water pressure does not act on the outdoor side surface portion 100 of the panel 1, the middle column 9 is not pushed by the panel 1 and unnecessary force does not act on the middle column 9, and the horizontal compression state. When water pressure is applied to the outdoor side surface portion 100 of the panel 1 in the fully closed state (vertical compression state), the indoor side surface portion 101 of the panel 1 deformed to the indoor side comes into contact with the middle pillar 9, thereby stopping the water. The panel 1 and the middle pillar 9 in FIG.

Similarly, when the panel 1 is in a non-horizontal compression state, the gap G1 is formed between the indoor side surface portion 101 of the panel 1 and the first surface 900 of the middle pillar 9 in the installation posture. This prevents the indoor side surface portion 101 from contacting the first surface 900 of the middle pillar 9 and allows the shutter curtain to be opened and closed with the middle pillar 9 installed.

A receiving member unit 99 is embedded in the floor corresponding to the installation position of the middle pillar 9. The receiving member unit 99 has a receiving box 990 provided with locking receiving holes 930 and 940 formed at intervals in an indoor / outdoor direction (a direction orthogonal to the opening width direction). In plan view, the locking receiving hole 930 is located on the side close to the indoor side surface portion 101 of the panel 1 in the fully closed posture, and the locking receiving hole 940 is located on the side far from the indoor side surface portion 101 of the panel 1 in the fully closed posture. ing. The receiving member unit 99 includes a lid body 991 that closes the upper surface of the receiving box 990 and conceals the locking receiving holes 930 and 940. When the lid body 991 is in the closed position, the upper surface of the lid body 991 and the floor surface Are on the same plane.

A first locking piece 992 is formed on the distal end side (one side in the opening width direction) of the lid 991, and a second locking piece 993 is formed on the base end side (the other side in the opening width direction). In the closed posture of the lid 991, the first locking piece 992 is connected to the first locked portion 995 of the receiving box 990 and the second locking piece 993 is connected to the second locked portion 996 of the receiving box 990, respectively. Locked. The first locking piece 992 can be rotated by a key operation from a key hole 997 formed in the lid 991, and the first locking piece 992 is rotated to engage with the first locked portion 995. By releasing the stopped state and lifting the tip end side of the lid 991 obliquely upward, the locked state between the second locking piece 993 and the second locked portion 996 is also released, and the lid 991 can be removed. it can.

In the receiving box 990, a groove portion 994 is formed on the base end side of the lid 991. The groove portion 994 is formed on the opposite side to the storage position side of the middle column 9 with respect to the locking receiving holes 930 and 940, and extends in the indoor / outdoor direction (direction orthogonal to the opening width direction). When the removed lid 991 is in a vertical posture, the upper surface of the lid 991 is closer to the latch receiving holes 930 and 940, and the lower surface of the lid 991 on which the first locking piece 992 is formed is the latch receiving hole 930. , 940 is positioned on the side far from 940 and inserted into the groove 994, and this vertical posture is maintained. In the middle column 9 at the installation position, the lower end portion of the third surface 902 which is the vertical surface of the middle column 9 is brought into contact with the upper surface which is the vertical surface of the lid body 991 in the vertical posture, so , 940, the lower locking rods 93, 94 are positioned directly above.

In this way, by disposing the middle column 9 on the indoor side of the shutter curtain in the fully closed state (vertical compression state and horizontal compression state), the water pressure that can act on the shutter curtain in the water stop state is countered. I am doing so. When the shutter curtain is deformed in a bulging shape indoors due to the water pressure from the outdoor side, the indoor side surface portion (the indoor side surface portion 101 of the panel 1) of the shutter curtain is abutted and supported by the first surface 900 of the middle column 9. The panel 1 and the middle pillar 9 in the water stop state prevent excessive deformation of the shutter curtain in the water stop state, and thus the water stop state is maintained. The middle column 9 is a long member having a rectangular shape in cross section, and in this embodiment, the long axis direction of the middle column 9 in the installation posture is the indoor / outdoor direction, and the water pressure acting from the outdoor side to the indoor side Can be fully competed.

The rail base 19 has a horizontal portion 190 fixed to a support member 192 (welding, screwing, etc.), and a vertical portion 191 having a first side 181 of the support bracket 18 fixed (welding, screwing, etc.). Yes. A receiving member 193 formed with a locking receiving hole 920 is fixed (welded, screwed, etc.) to a predetermined portion in the length direction of the support member 192 (a portion corresponding to the installation position of the middle column 9).

The hanger rail 90 extends over the entire width of the opening width, but a part of the length direction is removable as an intermediate hanger rail 90 'so that the middle pillar 9 can be attached and removed during maintenance. (In FIG. 28, the intermediate hanger rail 90 'is omitted). As shown in FIG. 29, by providing an intermediate hanger rail 90 ', the hanger rail 90 can be used as an intermediate hanger rail 90' between the first part 90A, the second part 90B, and the first part and the second part. And is divided into The intermediate hanger rail 90 ′ only needs to have at least a length dimension such that the space when the intermediate hanger rail 90 ′ is removed is such that the middle pillar 9 can be removed, and may be relatively short. .

The intermediate hanger rail 90 'has the same cross-sectional shape and dimensions as the first portion 90A and the second portion 90B of the hanger rail 90 (the main hanger rail on which the middle column 9 travels), and the horizontal upper side 9000. And the vertical first side 9001 and second side 9002 extending downward from the end of the upper side 9000 in the width direction (inside and outside direction or in the direction orthogonal to the length direction), respectively, and the lower end of the first side 9001 The first rail side 9003 is formed, and the second rail side 9004 is formed at the lower end of the second side 9002.

The intermediate hanger rail 90 'causes the lengthwise edges thereof to be close to (a slight gap between) or contact the lengthwise edges of the first portion 90A and the second portion 90B, respectively. In this state, the joint 194 and the screw 195 are connected to the first portion 90A and the second portion 90B. The screw 195 can be tightened or loosened by inserting a screwdriver from the gap below the hanger rail (the gap between the first rail side 9003 and the second rail side 9004) through which the suspension shaft 910 of the middle column 9 passes. The screw 195 can be tightened or loosened using the gap. The joint 194 has a substantially U-shaped cross-sectional view from an upper side 1940 and drooping sides 1941, 1942. The upper side 1940 has a hanger rail 90 (first portion 90A, second portion 90B, intermediate hanger rail 90 '). The width dimension is slightly larger than the upper side 9000. One half of the length of the joint 194 is fixed to the end of the first portion 90A and the end of the second portion 90B with screws. The other half of the length of the joint 194 extends from the end of the first portion 90A and the end of the second portion 90B in a take-out shape. In one embodiment, the half of the upper side 1940 of the upper side 1940 of the joint 194 is brought into contact with the lengthwise end of the upper side 9000 of the first portion 90A and the lengthwise end of the upper side 9000 of the second portion 90B. However, the fixing means is not limited and welding may be used.

When the longitudinal edge of the intermediate hanger rail 90 'is brought into contact with the longitudinal edge of the first portion 90A and the longitudinal edge of the second portion 90B, respectively, the upper side of the intermediate hanger rail 90' Both end portions in the longitudinal direction of 9000 are in contact with the other half in the longitudinal direction of the upper side 1940 of the joint 194 from below, and in this contact state, the intermediate hanger rail 90 ′ is in contact with the screw 195 from below. The upper side 9000 and the upper side 1940 of the joint 194 are connected. At this time, since there is a gap between the first rail side 9003 and the second rail side 9004 of the intermediate hanger rail 90 ', the screw 195 can be inserted from this gap. Therefore, in a state where the waterproof door is installed in the opening, the intermediate hanger rail 90 'can be removed, and by removing the intermediate hanger rail 90', the middle pillar 9 can be removed for maintenance, replacement, etc. it can. Further, since the screw 195 is concealed in the intermediate hanger rail 90 ', it is not exposed to the outside and the appearance is good. The support bracket 18 is not provided on the intermediate hanger rail 90 'and does not hinder the attachment / detachment of the intermediate hanger rail 90'. Further, as will be described later, since the intermediate hanger rail 90 'is provided outside the movement range of the middle column 9, high strength is not necessarily required for the connection between the intermediate hanger rail 90' and the first portion 90A and the second portion 90B. .

In one aspect, the third contact portion 276 can be manually changed between the protruding posture and the retracted posture, but the posture may be automatically changed. For example, the third contact portion 276 may be automatically rotated from the retracted position to the protruding position by detecting that the middle column 9A has moved to the storage position. For example, the retracted posture is detected by detecting the contact between the lower end portion of the middle column 9A and the first abutting portion 274, or one or more of the upper locking rod 92 and the lower locking rods 94, 93 projecting. It is good also considering the 3rd contact part 276 in a protrusion attitude | position. Alternatively, the third contact portion 276 in the protruding posture may be changed to the retracted posture by detecting that the middle column 9B has moved from the storage position. For example, the release of the contact state between the lower end portion of the middle column 9B and the third contact portion 276 and the retraction of all of the upper locking rod 92 and the lower locking rods 94 and 93 from the protruding posture to the storage posture are detected. Thus, the third contact portion 276 in the protruding posture may be set in the retracted posture.

[Stop button S3 (Stop switch)]
When the stop button S3 is pressed during the operation of the shutter or during the compression operation and the compression release, the operated shutter curtain stops the operation at an arbitrary position. More specifically, when the stop button S3 is pushed while the panel 1 is raised, the raising is stopped, when the stop button S3 is pushed while the panel 1 is lowered, the descent is stopped, and the stop button S3 is pressed during the compression operation. When pressed, the compression operation stops, and when the stop button S3 is pressed during the pressure release, the pressure release operation stops.

[Pressing button S4 (pressing switch)]
When the shutter is in the fully closed position and is not in the compressed state (vertical compressed state and horizontal compressed state), pressing the compression button S4 starts a compression operation for obtaining a water stop structure. When the compression operation is completed, the compression button S4 is turned on. In the present embodiment, when the compression button S4 is pressed in the fully closed state (including the case where the stop button S3 is pressed during the compression operation), first, the first compression mechanism 7 is pressed to enter the fully closed posture. Each panel 1 is squeezed vertically downward. When the pressing operation of the first compression mechanism 7 is completed (a vertical compression state signal is generated when the second limit switch 74 of the first compression mechanism 7 is turned ON), the second compression mechanism 8 starts the pressing operation, and high All the panels 1 pressed in the vertical direction are integrally compressed toward the indoor side. When the pressing operation of the second compression mechanism 8 is completed (the second limit switch of the second compression mechanism 8 is turned ON and a horizontal compression state signal is generated), the compression button S4 is lit (for example, lit red).

[Pressure release button S5 (Pressure release switch)]
When the shutter is in the compressed state, or when the shutter is in the fully closed position and not in the compressed release state (when the compression release button is off), pressing the compression release button S5 starts the compression release operation. When the compression release operation is completed, the compression release button S5 is lit. In the present embodiment, when the compression release button S5 is pressed in the compression state (including the case where the stop button S3 is pressed during the compression release operation), the first compression mechanism 7 and the second compression mechanism 8 are released. The compressed state is released. As one procedure, when the compression release button S5 is pressed, first, the second compression mechanism 8 starts the release operation, and when the release operation of the second compression mechanism 8 is completed (when the first limit switch is turned ON, The compression state release signal is generated), and the first compression mechanism 7 starts the release operation. When the compression release operation of the first compression mechanism 7 is completed (a vertical compression state release signal is generated when the first limit switch 73 of the first compression mechanism 7 is turned on), the compression release button S5 is lit (for example, lit in green) )

[Emergency closing button S6]
When the shutter is not in the fully closed position, the shutter curtain can be lowered by the push-off operation by pressing the emergency close button S6. While descending, the input of the photoelectric sensor 6 and the emergency switch input are invalid. When descending to the fully closed position, the compression operation is automatically started, and after the compression operation is completed, the compression button S4 is lit. When the emergency close button S6 is pressed in the fully closed position, the same operation as the compression button S4 is performed. That is, the emergency closing button S6 has a function as a compression switch.

The operation switch (operation unit) is summarized as follows. The operation switch includes a first switch (pressure button, emergency closing button) for setting the door body in a water stop state, and a second switch (pressure release button) for releasing the water stop state. The plurality of buttons described above is one preferred embodiment of the operation switch. For example, the emergency closing button may be arbitrary. The first switch includes a switch for setting the door body in the fully closed state to a water stop state, and a switch for setting the door body in the fully open state or the half open state to a fully closed state and a water stop state. In the latter case, for example, when there is an input from the first switch, the door in the fully open state or the half open state is in a fully closed state (non-water stop state), and then automatically based on the detection of the fully closed state. It is conceivable that the water stops. That is, in the case of a waterproof door, the closing button and the compression button may be configured by a common button to serve as the first switch, and a series of closing / compression may be performed by an operation from the common button. In this embodiment, the fully closed state of the door body during normal use is a non-water-stopped state, but in a waterproof door, the fully closed state of the door body may be a water-stopped state. For example, when the close switch is pressed in the fully open state, the fully closed state (water stop state) is entered, and when the open switch is pressed in the fully closed state (water stop state), the fully open state (non-water stop state) is entered. In this case, the closing switch is the first switch and the opening switch is the second switch. The first switch and the second switch may be composed of one button. For example, it may function as a second switch when the button is pressed in a water-stopped state, and may function as a first switch when the button is pressed in a non-water-stopped state. Or you may make it identify a 1st switch and a 2nd switch by input operation (pressing time, frequency | count, these combinations, etc.).

In this embodiment, in addition to the operation input from the first outdoor switch box SB1, the second outdoor switch box SB2, and the indoor switch box SB3, remote operation input from the management room (confirm safety with a monitoring camera or the like) Operation is possible. A series of operation control of the shutter can be performed by a remote operation signal (DC24V voltage a contact), and a compression operation and a compression release operation can also be performed by remote operation.

In addition to the detection by the obstacle detection means, when the shutter detects an abnormality, the following operation control is performed.
When a guide rail abnormality is detected by a guide rail safety switch input, shutter operation (up / down / compression / compression release) is prohibited.
When chain looseness abnormality is detected by the chain looseness detection switch input, shutter operation (up / down / pressure / pressure release) is prohibited.
While the emergency switch is being input, the ascending operation is prohibited and the descending operation can be performed by a push-off operation. The pressing / releasing operation is possible if the condition (shutter fully closed position) is satisfied.
In the case of a thermal abnormality, both ascending and descending operations are prohibited. The pressing / releasing operation is possible if the condition (shutter fully closed position) is satisfied.
In the case of an overtime abnormality (ascending / descending), specifically, if the ascending / descending operation continues for a predetermined time (for example, 90 seconds or more), an overtime abnormality occurs and the ascending / descending operation is stopped. Ascent and descent operations are prohibited when the overtime is abnormal. The pressing / releasing operation is possible if the condition (shutter fully closed position) is satisfied.
In the case of an overtime abnormality (compression / compression release), specifically, if the compression operation / compression release operation continues for a predetermined time (for example, 20 seconds or more), an overtime abnormality occurs and the compression operation / compression release operation is stopped. Pressing and releasing operations when overtime is abnormal are prohibited. The overtime error can be canceled by pressing the stop button on the operation switch for 1 second or longer.
When the earth leakage detector is activated, abnormal output is performed, but each operation of ascending, descending, pressing, and releasing the compression is possible.

The relay contact output used for operation control of the waterproof door according to the present embodiment will be described. The transfer contact output is, for example, outputting an operation control signal for a waterproof door to a control device in a management room remote from the waterproof door. In the waterproof door, the following relay contact output (no-voltage c contact output) is performed according to the state of the shutter.
Upper limit position signal: Output when the shutter is fully open.
Lower limit position signal: Output when the shutter is fully closed.
Vertical compression release state signal: Output when vertical compression is released.
Vertical compression state signal: Output when the vertical compression is completed.
Horizontal compression release state signal: Output when horizontal compression is released.
Horizontal compression state signal: Output when horizontal compression is completed.
Abnormal signal: Output when the above shutter abnormality occurs.

A basic operation control flow of the waterproof door according to the present embodiment will be described with reference to FIG. When the closing button S2 of the operation unit (any one of the switch boxes SB1, SB2, SB3) is pressed in the fully opened state or half-opened state of the opening, the switch M is activated and the panel 1 starts to descend. The lower limit switch detects that the shutter curtain has been lowered to the fully closed position, a lower limit position signal is generated, the operation of the switch M is stopped, and the opening is fully closed.

When the compression button S4 is pressed, the first compression mechanism 7 is activated on the condition that a lower limit position signal is generated, and a vertical compression operation is started. The second limit switch 74 detects that the shutter curtain has been pressed down to the vertical compression state, generates a vertical compression state detection signal, and the operation of the first compression mechanism 7 stops. At the same time or shortly thereafter, the second compression mechanism 8 is activated based on the input of the vertical compression state detection signal to start the horizontal compression operation. The second limit switch 84 detects that the shutter curtain has been pressed indoors until the horizontal compression state, a horizontal compression state detection signal is generated, the operation of the second compression mechanism 8 is stopped, and the compression state is completed. When the shutter curtain is not fully closed (the lower limit position signal is not generated) or when the shutter curtain is in the vertical compression state (the vertical compression state detection signal is generated), the first compression mechanism The compression operation invalidating unit 7 invalidates the vertical compression operation by the compression operation input from the compression button S4. When the shutter curtain is not in the vertical compression state (the vertical compression state detection signal is not generated) or when the shutter curtain is in the horizontal compression state (the horizontal compression state detection signal is generated), the second By the compression operation invalidating means of the compression mechanism 8, the horizontal compression operation by the compression operation input from the compression button S4 is invalidated.

When the compression release button S5 is pressed, the second compression mechanism 8 is activated on the condition that the shutter curtain is in the compression state (the horizontal compression state detection signal is valid), and the release of the horizontal compression state is started. . The first limit switch 83 detects that the shutter curtain has been released from the horizontal compression state, a horizontal compression state release signal is generated, and the operation of the second compression mechanism 8 is stopped. At the same time or shortly thereafter, the first compression mechanism 7 is activated based on the input of the horizontal compression state release signal, and the release of the vertical compression state is started. The release of the vertical compression state of the shutter curtain is detected by the first limit switch 73, a vertical compression state release signal is generated, and the operation of the first compression mechanism 7 is stopped. When the shutter curtain is in the horizontal compression release state (the horizontal compression state release signal has been generated), the horizontal release by the compression release operation input from the compression release button S5 by the compression release operation invalid means of the second compression mechanism 8 is performed. The release operation of the compressed state becomes invalid. When the shutter curtain is in the non-horizontal compression release state (the horizontal compression state release signal has not been generated), or when the shutter curtain is not in the vertical compression state (the vertical compression state release signal has been generated), By the compression release operation invalid means of the first compression mechanism 7, the release operation of the vertical compression state by the input of the compression release operation from the compression release button S5 is invalidated.

When the emergency close button S6 is pressed in the fully open state or half open state of the opening, the compression operation is automatically started based on the input of the lower limit position signal (instead of pressing the compression button).

When the compression button S4 or the emergency closing button S6 is pressed, or when the waterproof door is in a compression state by remote operation, the operation from the buttons other than the compression release button S5 is invalid. That is, in principle, when the waterproof door is in the compressed state, only the compression release button S5 functions as an effective button that can be operated. Here, the waterproof door according to the present embodiment includes a disabling unit for the compression release button S5 of the first outdoor switch box SB1.

In the present embodiment, when the fully closed shutter curtain is completely compressed, the input from the compression release button S5 of the first outdoor switch box SB1 is invalidated. Specifically, when one of the compression buttons 4 of the first outdoor switch box SB1, the second outdoor switch box SB2, and the indoor switch box SB3 is pressed, the first compression mechanism 7 and the second compression mechanism 8 are When the compression operation is sequentially performed and the compression operation of the second compression mechanism 8 is completed, that is, when the second limit switch of the second compression mechanism 8 is turned on (when the horizontal compression state signal is output), The first outdoor switch box SB1 is in a disabled state or a locked state in which input from the compression release switch S5 cannot be performed. By doing in this way, the malfunction (incorrect input of the pressure release switch S5) when the 1st outdoor side switch box SB1 is submerged or flooded in the water stop state is prevented.

The flow from the input of the compression switch to the invalidation of the input of the compression release switch of the outdoor operation unit will be described with reference to FIG. First, in this embodiment, in order for a predetermined compression operation to be activated by an input of the compression switch, it is a condition that the door body is in a fully closed state and a non-compressed state. When this condition is satisfied, the first compression mechanism (vertical compression mechanism) is activated. Whether or not the door body is in the fully closed state can be determined by the presence or absence of the output of the lower limit position signal. Whether or not the door body is in the compressed state can be determined by the presence or absence of the output of the horizontal compressed state signal.

When the first compression mechanism is activated and the vertical compression state is completed, the second compression mechanism (horizontal compression mechanism) starts to operate. Whether or not the door body is in the vertical compression state is determined based on whether or not a vertical compression state signal is output. When the stop switch is input during the operation of the second compression mechanism and the compression switch is input after that, the vertical compression state has already been completed, so the second compression mechanism is operated again. .

When the door body is in the horizontal compression state, the operation of the second compression mechanism is finished. Whether or not the door body is in a horizontal compression state can be determined based on whether or not a horizontal compression state signal is output. When the door body is in a horizontal compression state, the door body is in a water stop state (compression completion state).

When the door body is in the compression completion state, the input from the compression release switch of the outdoor operation unit (first outdoor switch box SB1) is invalidated. Therefore, when the door body is in the compression completion state, the switch input becomes invalid even if the compression release switch input of the outdoor operation unit is performed. Here, several modes can be considered for disabling the compression release switch of the outdoor operation unit (first outdoor switch box SB1), or when disabling individual switches including at least the compression release switch, or The case where the whole outdoor operation part is invalidated is illustrated. Further, the invalidation of the switch can be exemplified when the predetermined signal itself is not generated by the switch operation or when the predetermined operation itself based on the generated predetermined signal is invalidated.

When the shutter curtain is in the vertical compression state and the horizontal compression state, that is, in the water stop state, the compression release button S5 of the second outdoor switch box SB2 and the indoor switch box SB3 is effective, and the second outdoor switch By pressing the compression release button S5 of either the box SB2 or the indoor switch box SB3, the compression state of the shutter curtain can be released.

The waterproof door according to the present embodiment includes an enabling means or a lock releasing means for the compression release button S5 of the disabled first outdoor switch box SB1. The unlocking operation of the first outdoor switch box SB1 will be described. As shown in FIG. 50, the invalidation state of the compression release switch is released by a preset switch combination operation. The release state of the pressure release switch is canceled for a certain period of time, and if there is an input from the pressure release switch within the fixed time, the input of the pressure release switch is valid and the input of the pressure release switch is within the fixed time. If there is no, the pressure release switch is disabled. In one embodiment, unlocking is performed by the following procedure.
(A) While pressing the stop button S3 of the first outdoor switch box SB1, the buttons other than the emergency close button S6 (open button S1, close button S2, pressure button S4, pressure release button S5) are simultaneously pressed for 5 seconds. .
The above operation is merely an example, and any other combination can be adopted.
(A) The emergency close button S6 and the compression button S4 blink alternately twice to notify the unlocking.
The means for informing the unlocking is not limited to this, and for example, a sound may be output for a predetermined time.
(C) The lock is released for 5 seconds after (a) starts alternately flashing. By pressing the compression release button S5 within 5 seconds, the compression release button S5 is effectively input, and the compression state is released. After the compressed state is released, the locked state is not entered unless the compression button S4 is pressed again. If the operation of the compression release button S5 is not performed within 5 seconds, the locked state is entered again.
In the above aspect, the compression release switch invalidation state of the first outdoor switch box SB1 is released only when a preset switch combination operation is performed on the first outdoor switch box SB1.
It should be noted that when an input operation is performed on a switch other than the first outdoor switch box SB1, that is, the compression release button S5 of either the second outdoor switch box SB2 or the indoor switch box SB3, the first outdoor switch The disabling state of the pressure release switch in the box SB1 may be released.

If the first outdoor switch box SB1 is not submerged or submerged after the waterproof door is in the compressed state, the lock release button S5 of the first outdoor switch box SB1 is locked by releasing the lock. By releasing the state and pressing the pressure release button S5, the pressure state of the waterproof door is released. Thereafter, the first outdoor switch box SB1 can be continuously used as effective. In addition, the reliability of the first outdoor switch box SB1 can be confirmed when the locked state is released. If the first outdoor switch box SB1 is submerged or the lock state cannot be released satisfactorily, it may be replaced with a new switch.
