[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 FIG. 1 and FIG. 2, 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 portions 2 for guiding. In FIG. 2, 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. 3, 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. 3 and 10 (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 FIGS. 4 and 10) via the support shaft 10 and is suspended to form a shutter curtain. Although the chain is omitted in FIG. 2 and the like, it should be noted that in the panel shutter, the 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 two arbitrary panels 1 adjacent in the vertical direction (FIG. 5C, FIG. 6, FIG. 7, 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. 5B and 8). Further, 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. 5A and 9).

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. As shown in FIGS. 6 and 7, 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. 4 to 9) 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. 6 and 7, 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. 9 (see FIG. 9), the outdoor horizontal part 121 of the watertight rubber 12 of the panel 1 and the upper part of the indoor horizontal part 122 (shown by hatching in FIGS. 6 to 9; 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. 8). 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. 9), 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, 2, and 5) is provided at the lower end of the lowest 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. 3 and 6 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. 5C, 6, and 7). 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. 6 and 7, on the upper end side of the outdoor side surface portion 100 of the lower panel 1, a rising piece (outdoor vertical) extending vertically upward 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 apparent from FIGS. 6 to 9, 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 1012 are substantially the same. As apparent from FIGS. 6 to 9, 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. 10). Both end portions in the width direction of the panel 1 are received in the guide portion 2, and the cutout portion of the indoor vertical piece 1010 is formed in the guide portion 2. Watertight rubbers 17 are provided at both ends in the width direction of the indoor side stepped portion 1011 (sites located in the guide portion) corresponding to the notches of the indoor vertical piece 1010 (see FIGS. 7 to 10).

The water-tight rubber 17 has a shape substantially corresponding to the notch (horizontally long square in the illustrated embodiment) and area, and a thickness slightly larger than the step size of the indoor side step portion 1011 (as shown in FIGS. 7 to 9, The panel has a thickness slightly protruding from the indoor side surface portion 101 of the panel), and is attached so as to cover both ends of the indoor side stepped portion 1011 in the width direction. The upper end portion of the watertight rubber 17 is in contact with or integrated with the indoor horizontal portion 122 of the watertight rubber 12 (in the case where the watertight rubber 12 and the watertight rubber 17 are formed separately). M) ensuring watertightness. As shown in FIG. 9, in the vertical compression state, the indoor side horizontal surface 1032 of the lower end surface 103 of the upper panel 1 is in pressure contact with the indoor side horizontal portion 122 of the watertight rubber 12 and the upper end of the watertight rubber 17.

In the illustrated embodiment, the storage space of the panel 1 above the opening is formed from the upper part of the opening toward the indoor side, and the panel 1 that has moved into the storage space is guided by the storage rail 5 while the guide roller 11 is guided. The room-side vertical piece 1010 of the upper panel 1 is sequentially sent to the rear of the storage space so as to be separated from the room-side stepped portion 1011 of the lower panel 1. In addition, in two adjacent panels, the outdoor vertical piece, the panel on which the outdoor step portion is formed, the indoor vertical piece, and the panel on which the indoor step portion is formed are limited to the illustrated embodiments. Instead, for example, when the storage space is formed from the upper part of the opening toward the outdoor side, the indoor side stepped part 1011 is formed on the upper panel 1, and the indoor side vertical piece 1010 is formed on the lower panel 1. The formed standing pieces and the water-tight rubber 17 are provided at both ends in the width direction of the indoor side step portion of the upper panel. Alternatively, the outdoor vertical piece and the indoor vertical piece may be formed on the same side panel (for example, the upper panel), and the outdoor stepped portion and the indoor stepped portion may be formed on the same side panel (for example, the lower panel). It will be understood by those skilled in the art that in these cases, the mode in which the watertight rubber 17 is provided can be changed as appropriate.

As shown in FIGS. 3 and 11, the guide portion 2 is a long member formed in a U shape in a sectional view from the outdoor side 20 and the indoor side 21 and the bottom 22 which are opposed to each other. Bending pieces 200 and 210 are formed so that the front end sides of the outer side 20 and the indoor side 21 are opposed to each other, and the widthwise end of the panel 1 is received in the opening groove between the ends of the bending pieces 200 and 210. It has become. More specifically, the inner surface on the distal end side of the outdoor side 20 has a rectangular shape in cross section, and is a horizontal pressing member 23 (an upper end of the horizontal pressing member 23 is a storage space) that is a long member extending in the height direction. The watertight rubber member 24, which is a long member extending in the height direction, is provided on the inner surface on the front end side of the indoor side 21 and the bottom 22 extends in the height direction. A guide member 25 that is a long member and that contacts and guides the outer peripheral surface of the guide roller 11 is provided. The horizontal pressing member 23 extends in the indoor / outdoor direction along the bent piece 200 in a plan view, and the distal end surface (the portion that contacts the outdoor side surface portion 100 of the panel 1 at the time of compression) is always (at the time of compression and When not compressed), it protrudes beyond the tip of the bent piece 200. It should be noted that the tip surface of the horizontal pressing member 23 is positioned inside the bent piece 200 when not compressed (does not exceed the tip), and the tip surface of the horizontal pressing member 23 exceeds the tip of the bent piece 200 when pressed. You may make it protrude. On the outer sides of the bent pieces 200 and 210 on the distal end side of the outdoor side 20 and the indoor side 21, fins 26 made of long elastic rubber respectively extending in the height direction are formed. Moreover, the guide part 2 is provided with upper side extension part 2 'extended to the storage space above an opening part.

As shown in FIGS. 3 and 11, the width direction end of each panel 1 is received in an opening between the outdoor horizontal pressing member 23 and the indoor watertight rubber member 24. The outdoor peripheral surface of the guide roller 11 at the tip of the support shaft 10 protruding from the end in the direction is in contact with or close to the guide member 25 provided on the bottom side of the guide body 2. By moving the chain 3 up and down, each panel 1 has an outdoor side surface portion and an indoor side surface portion in contact with the fins 26, while the outdoor peripheral surface of the guide roller 11 of the support shaft 10 at both ends in the width direction is the guide member 25. In addition, both ends in the width direction are guided by the water-tight rubber member 24 and move up and down in the vertical direction. When the outdoor peripheral surface of the guide roller 11 is in contact with the guide member 25, contact between the metal horizontal pressing member 23 and the width direction end of the panel 1 is restricted during normal opening and closing and in a normal fully closed state. Has been.

The horizontal direction pressing member 23 and the watertight rubber member 24 are opposed to each other with an end portion in the width direction of the panel 1 interposed therebetween, and the indoor peripheral surface of the guide roller 11 is free (not guided by the member). ), The guide roller 11 can also move indoors as the panel 1 moves indoors, and by pressing the end of the panel 1 indoors by the horizontal pressing member 23, The width direction end portion (including the watertight rubber 17) of the indoor side surface portion of the panel 1 is brought into pressure contact with the watertight rubber member 24, and a water stop structure is obtained across the height direction of both ends of the shutter curtain width direction. At this time, the watertight rubber 17 having a thickness slightly protruding from the indoor side surface portion 101 of the panel 1 is pressed against the watertight rubber member 24 and compressed in the thickness direction, so that the indoor side surface portion 101 and the watertight rubber 17 are It will be the same. In the lower diagram of FIG. 20, in the left diagram (water-stopped state), the horizontal direction pressing member 23 is in press contact with the outdoor side surface portion 100 of the panel 1, and the indoor side surface portion 101 of the panel 1 is in contact with the watertight rubber member 24. In the right figure (non-water-stop state), the horizontal direction pressing member 23 and the outdoor side surface portion 100 of the panel 1, and the indoor side surface portion 101 of the panel 1 and the watertight rubber member 24 are pressed in close proximity. Not in state. Thus, by providing the guide member 25 that can contact the guide roller 11 only from the outdoor side inside the guide body 2, the indoor side surface portion 101 (watertight rubber) of the panel 1 by the compression operation of the second compression mechanism 8 is provided. 17) and the watertight rubber member 24 are allowed to be pressed, while the guide roller 11 is in contact with the guide member 25, so that the horizontal pressing member 23 and the outdoor side surface portion 100 of the panel 1 are in contact with each other when the panel 1 is moved up and down. To be regulated.

In the state where the shutter curtain is vertically compressed, the watertight rubber 12 closes the upper and lower adjacent panels 1 in a watertight state, and the watertight rubber 13 closes in a watertight state between the lower end of the lowermost panel 1 and the floor surface. When the shutter curtain in the vertical compression state is further compressed in the horizontal direction and is in the horizontal compression state, the indoor side surface portion 101 and the watertight rubber 17 of the panel 1 are pressed against the watertight rubber member 24, and both ends in the opening width direction are watertight. Block to state. When the shutter curtain is in a compressed state (vertical compressed state and horizontal compressed state) in this way, the upper and lower panels are closed in a watertight manner, and the shutter device has three sides (the shutter curtains located in the left and right guide bodies 2). Water-tight rubbers 13 and 24 at both ends in the width direction and the lower end of the shutter curtain form a water stop line that prevents water from entering the indoor space.

[B-2] A waterproof door can be configured by providing a water stop structure to the panel shutter in the fully closed state of the compression mechanism.

Therefore, when the actuating rod is pressed in the vertical direction to apply a compressive force to the actuating rod. Compared to the above, it is not necessary to consider the buckling of the actuating rod 234, and the actuating rod 234 can be made of a lighter member having lower strength (smaller cross-sectional dimensions and more space saving) and lighter weight. Become.

As shown in FIGS. 16 to 18, the second compression mechanism 8 includes a first limit switch 83 and a second limit switch 84.

By disposing the middle column 9 on the indoor side of the shutter curtain in the fully closed state, the water pressure that can act on the shutter curtain in the water stop state is countered. When the shutter curtain is deformed in a bulging shape indoors due to the water pressure from the outside of the room, the indoor side surface portion (the indoor side surface portion of the panel 1) of the shutter curtain is abutted and supported by the middle column 9, so that Deformation is prevented. The middle column 9 is a long member having a rectangular shape in cross section. In the present embodiment, as shown in FIGS. 2 and 22, in the installation posture, the longitudinal direction in the cross section is the indoor / outdoor direction, and the outdoor side The water pressure acting on the indoor side can be fully countered.

[C] Waterproof Door Operation Control Device The waterproof door according to the present embodiment includes a shutter curtain (comprising a plurality of panels 1) for closing a building opening and a shutter curtain including a plurality of panels 1. A first compression mechanism 7 that compresses the shutter curtain in the vertical direction, a second compression mechanism 8 that compresses the shutter curtain composed of the plurality of panels 1 in the horizontal direction, and that the shutter curtain is in a fully closed state. Fully closed state detection means for detecting (for example, a lower limit switch) and vertical compression state detection means for detecting that the shutter curtain is in the vertical compression state (first limit switch 73, second limit switch 74). ) And horizontal compression state detection means (first limit switch 83, second limit switch) for detecting that the shutter curtain is in the horizontal compression state. Is provided with a switch 84), the.

The compression operation of the first compression mechanism 7 operates on the condition that the fully closed state of the opening is detected by the fully closed state detection unit, and stops when the vertical compression state is detected by the vertical compression state detection unit. To do. The first compression mechanism 7 performs a compression operation based on a first input signal for causing the first compression mechanism 7 to perform a compression operation, and the first input signal is an opening portion fully closed state by the fully closed state detecting means. It is invalid at the time of non-detection or when the vertical compression state is detected by the vertical compression state detection means, and is effective at the time of detection of the fully closed state of the opening by the full-closed state detection means and when the vertical compression state is not detected by the vertical compression state detection means is there. That is, the motion control device compresses the first compression mechanism that invalidates the first input signal when the fully closed state detection unit does not detect the opening fully closed state or when the vertical compression state detection unit detects the vertical compression state. An operation invalidation means is provided.

The compression operation of the second compression mechanism 8 operates on the condition that the vertical compression state of the door body in the fully closed state is detected by the vertical compression state detection unit, and the horizontal compression state is detected by the horizontal compression state detection unit. Stop when is detected. The second compression mechanism 8 performs a compression operation based on a second input signal for causing the second compression mechanism 8 to perform a compression operation, and the second input signal is not detected by the vertical compression state detection unit. It is invalid when the horizontal compression state is detected by the horizontal compression state detection unit, or when the vertical compression state is detected by the vertical compression state detection unit and when the horizontal compression state is not detected by the horizontal compression state detection unit. That is, the motion control device invalidates the compression operation of the second compression mechanism that invalidates the second input signal when the vertical compression state is not detected by the vertical compression state detection unit or when the horizontal compression state is detected by the horizontal compression state detection unit. Means. In one aspect, as will be described later, the first input signal and the second input signal are generated based on one compression operation input from one switch (the compression button S4, the emergency close button S6). The one compression operation input functions as a first input signal from the detection of the fully closed state to the detection of the vertical compression state, and functions as the second input signal from the detection of the vertical compression state to the detection of the horizontal compression state. When the one compression operation input is performed in the vertical compression state, the one compression operation input functions as a second input signal.

The electric waterproof door according to the present embodiment is used as a so-called management panel shutter, and is also used for normal opening and closing of a building opening, and functions as a waterproof door in an emergency where heavy rain is expected. To do. As described below, the opening / closing control of the waterproof door is performed by an input from the operation switch.

As shown in FIG. 2, the prevention door according to the present embodiment includes a first outdoor switch box SB1, a second outdoor switch box SB2, and an indoor switch box SB3, that is, three operation switches. The first outdoor switch box SB1 and the indoor switch box SB3 are arranged at a height of 1500 mm from the floor so that they can be easily operated in a standing posture. The second outdoor switch box SB2 is disposed at a height exceeding 2000 mm (assumed maximum water level W.L.) from the floor surface.

The waterproof door is based on the premise that water collects in the outdoor part partitioned by the shutter curtain. Assuming maximum water level of 2000mm from the floor. L. In such a case, the first outdoor switch box SB1 may be submerged or submerged when the water stops. In the present embodiment, the first outdoor switch box SB1 is the same as a normal switch box and is not specially waterproofed. In the present embodiment, since the first outdoor switch box SB1 and the outdoor photoelectric sensor 6 may be submerged or submerged, the power system of the first outdoor switch box SB1 and the indoor photoelectric sensor 6 is By separating from the power supply system of other elements (the second outdoor switch box SB2 and the indoor switch box SB3), the other electric systems are not affected. In a specific example, AC200V is supplied to the waterproof door as a main power source, and the motor of the switch operates using AC200V. The main power supply is converted to the first power supply system (DC24V) and the second power supply system (DC24V) through at least two regulators, and the first outdoor switch box SB1 and the indoor / outdoor photoelectric sensor 6 are operated by the first power supply system. The second outdoor switch box SB2 and the indoor switch box SB3 are operated by the second power supply system. Even if a malfunction occurs in the first power supply system due to submergence or the like, the second power supply system and the main power supply are not affected.

FIG. 23 shows a switch box. The switch box includes a box 14 having an opening on the front surface, a lid 15 that opens and closes the opening on the front of the box 14, and an operation panel 16 provided on the box 14. The operation switch is provided. In the present embodiment, the operation panel 16 is provided with an open button S1, a close button S2, a stop button S3, a compression button S4, a compression release button S5, and an emergency close button S6. The operation of the waterproof door is controlled based on inputs from these buttons. More specifically, according to an instruction by button input, the switch M (up and down operation of the panel 1), the first compression mechanism 7 (vertical compression operation of the panel 1 in the fully closed state, vertical compression release operation) via the control unit ), Operation control of the second compression mechanism 8 (horizontal compression operation and horizontal compression release operation of the panel 1 in the vertical compression state) is performed. Hereinafter, each button will be described.

[Open button S1 (open switch)]
When the shutter is in a pressure release state (vertical pressure release state and horizontal pressure release state) and not in the fully open position, pressing the release button raises the shutter curtain and stops in the fully open position. In this embodiment, when the release button S1 is pressed, the sprocket 4 is rotationally driven in the direction of lifting the chain by the opening / closing machine M, and the panel 1 is in a fully closed state (non-vertical compression state and non-horizontal compression state) or a half-open state. Rises. When the panel 1 is moved up to a predetermined upper limit position, an upper limit position signal is generated by the upper limit switch, and driving by the switch M is stopped. The operation control apparatus according to the present embodiment includes an opening operation invalidating unit, and when the shutter is in a compressed state (vertical compression state and / or horizontal compression state), even if the release button is pressed by the opening operation invalidating unit. The opening operation is not performed.

[Close button S2 (Close switch)]
When the shutter is not in the fully closed position, when the close button S2 is pressed, the shutter curtain descends and stops at the fully closed position. In this embodiment, when the closing button S2 is pressed, the sprocket 4 is rotationally driven in the direction in which the chain is extended by the opening / closing machine M, and the panel 1 in the fully open state or the half open state is lowered. When the panel 1 is lowered to a predetermined lower limit position, a lower limit position signal is generated by the lower limit switch, and driving by the switch M is stopped.

[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. Pressing the stop button of the operation switch for 1 second or more cancels the overtime error.
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.

A 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. 25, 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 indoor switch box SB1 is locked by releasing the lock. The pressure release state of the waterproof door is released by releasing and pressing the pressure release button S5. 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.
