Description

  The present invention relates to a waterproof door device that also serves as a water stop plate.

  In recent years, the development of hinged door type waterproof doors (also called waterproof doors, etc.) has been promoted as a countermeasure against flooding caused by torrential rain (guerrilla heavy rain) or tsunami. If it exceeds 300 mm, there is a problem that it becomes extremely difficult to open and close the open door type door by water pressure. For this reason, the waterproof door does not open at the time of flooding, and there is an inconvenience that the waterproof door cannot be opened for evacuation.

  In Patent Document 1, the door plate is constituted by an upper door plate member and a lower door plate member connected to the upper door plate member by a connection release means, and an obstacle to opening and closing of the entire door is caused by water pressure due to water immersion or the like. In this case, a door of a building is disclosed in which the connection between the lower door plate member and the upper door plate member is released, and only the upper door plate member is opened to enable evacuation behavior.

  On the other hand, in order to keep the door and the frame closely in contact with each other and maintain the ability to prevent inundation, the waterproof door device has a door-like contact with the frame as in the waterproof structure of the door device of Patent Document 2, for example. And a seal member made of a rubber material or the like is mounted on the door, and the entire outer peripheral edge of the door is sealed.

JP 2014-114668 A JP 2006-205079 A

  However, when the door of the waterproof door device having the seal member as shown in Patent Document 2 is divided into an upper door member and a lower door member as in Patent Document 1, the outer periphery of the door with respect to the frame body Even if the seal member arranged in the entire range of the periphery is provided, there is a gap (for example, 3 mm gap) between the upper door member and the lower door member at the side periphery of the side of the door. Since it is not in contact, there is a problem that water will be submerged through the gap.

  In this respect, since the door of the building of Patent Document 1 is not a waterproof door, as shown in FIG. 4 of Patent Document 1, the seal member itself as shown in Patent Document 2 is provided on the outer periphery of the frame. Although not provided, a rain drain plate extending downward from the upper door plate member and a rain return plate extending upward from the lower door plate member are provided to connect the upper door plate member and the lower door plate member. The rain plate or rain return plate of one door plate member overlaps with the panel surface of the other door plate member, and the gap between the upper door member and the lower door member is eliminated.

  However, in the structure having the rain drain plate and the rain return plate such as the door of the building of Patent Document 1, the thickness of the rain drain plate or the rain return plate, the door panel, in the horizontal direction to the peripheral edge of the door An extending protrusion is formed. For this reason, when the door comes into contact with the seal member of the frame, the projection of the door comes into contact with the seal member of the frame before the panel surface of the door. In addition, the aesthetic appearance of the door is also impaired by the laterally extending protrusions formed on the outer surface of the door.

  Therefore, an object of the present invention is to provide a waterproof door device that can prevent inundation caused by dividing the door into upper and lower door members even if the door is composed of upper and lower door members.

  The waterproof door device according to the present invention includes an upper frame, a shoe positioned below the upper frame, and a frame body including two flange frames positioned between the upper frame and the shoe; A door that is rotatably attached to one of the two frame frames via a hinge mechanism, and that opens and closes an opening in the frame of the frame body. The door includes an upper door member and a lower door. The lower door member projects a door stop having a seal member that contacts the upper door member toward the upper door member, and the upper door member A recess having a standing wall portion that comes into contact with a seal member per door is formed in accordance with the protrusion amount of the door stop, and the upper door member is a waterproof rubber that comes into contact with the upper portion of the door stop. The water stop part provided with is provided above the hollow. It is characterized by a door. The upper door member and the lower door member can be connected to each other by a connecting device. By operating this connecting device, the upper door member and the lower door member are connected or released.

  Thereby, the seal member of the door of the lower door member comes into contact with the recessed wall of the upper door member while compressing, and the water stop rubber of the water stop portion of the upper door member further contacts the door of the lower door. Since the upper portion is pressed against the upper portion while being compressed, even if there is a gap for smoothly opening and closing the upper door member between the upper door member and the lower door member, the gap is closed with good sealing properties.

  The upper door member and the lower door member are combined into a vertically integrated door so that the door contact of the lower door member fits in the depression of the upper door member, so that the lower door member and the upper door member No projecting portion is formed at the boundary portion, and the boundary portion between the lower door member and the upper door member can be flush with the other surfaces of the lower door member and the upper door member.

  In the waterproof door device according to the invention of claim 2, the water stop portion is composed of a holder portion and a water stop rubber attached to the holder portion, and the upper door member of the holder portion. According to the thickness of the outer surface side portion, a protruding portion is formed on the water stop rubber.

  Thereby, in order to hold the water-stopping rubber with the holder portion having a structure having certainty and strength, the shape of the outer surface side portion of the upper door member in the holder portion is used as the folded portion, etc. Even if the side portion is relatively thick, the waterproof rubber has a protruding portion that fills the gap corresponding to the thickness of the outer portion of the upper door member in the holder portion. Therefore, a gap corresponding to the thickness of the outer surface side portion of the upper door member of the holder portion is formed between the water-stopping rubber and the lower end of the holder portion, and water is prevented from entering through the gap.

  In the waterproof door device according to a third aspect of the invention, the hinge mechanism is attached to one of the two shafts and the connection shaft laid between the frame body and the door, and the connection. A first support member having a first rotation shaft extending in a direction orthogonal to the shaft, and a second support member having a second rotation shaft attached to the door and extending in a direction orthogonal to the connection shaft And both ends of the connecting shaft are rotatably supported by the first and second support members via the first and second rotating shafts. .

  As a result, when the door opens and closes the space in the frame, the door is restricted from rotating around the first rotation axis and the second rotation axis is prevented from rotating. The second rotating shaft can be rotated when a predetermined pressure or more is applied to the door while the space is closed. Along with this, the door is pressed more strongly against the door of the frame than during normal opening and closing, so that the sealing performance between the door and the frame is improved. Therefore, even when the door cannot be opened and closed as a whole door in which the upper door member and the lower door member are connected by water pressure, the lower door member can function as a water stop plate.

  In the waterproof door device according to a fourth aspect of the present invention, the upper frame of the frame body has an extending portion extending on the opposite side to the door side of the door, and a grip portion is provided on the extending portion. And the lower door member has a footrest portion on the side opposite to the side having the grip portion.

  Thus, after opening only the upper door member, hold the grip part with both hands or one hand, and place one foot on the footrest of the lower door member, so that a certain height from the floor to the upper edge of the lower door member Even if it exists, it is possible to get over the lower door member and escape from the space in the frame opened by the upper door member to the opposite side of the door.

  As described above, according to the waterproof door device of the present invention, since only the upper door member can be opened and closed, only the upper door member is opened in an emergency when the door as a whole becomes difficult to open and close due to water immersion. Thus, it is possible to escape from the opening in the frame opened by the upper door member.

  Then, according to the waterproof door device according to the present invention, when it is desired to check the flooding state beyond the waterproof door after closing the waterproof door, only the upper door material is opened without opening the entire door. It is possible to check the flooding situation from the opening in the frame formed by opening the upper door member. Even in this case, since the lower door member functions as a water stop plate, it is possible to prevent water from entering.

  Furthermore, according to the waterproof door device according to the present invention, when the upper door member and the lower door member are combined so as to be an integrated door, the seal member for the door of the lower door member is a depression of the upper door member. Since the water stop rubber of the water stop portion of the upper door member is in contact with the upper door portion of the lower door while being compressed, the upper door member and the lower door member Even if there is a gap for smoothly opening and closing the upper door member, the gap can be closed with good sealing performance.

  In particular, according to the waterproof door device of the second aspect of the present invention, the shape of the outer surface side portion of the upper door member in the holder portion is folded back so that the waterproof rubber is securely held by the holder portion having a structure having strength. For example, even if the outer surface side portion of the upper door member of the holder portion is relatively thick, the water stop rubber has a gap corresponding to the thickness according to the thickness of the outer surface portion of the upper door member of the holder portion. The protrusion part which fills up is formed. Therefore, the water stop portion prevents a water gap from being generated between the water stop rubber and the lower end of the holder portion by a thickness corresponding to the thickness of the outer surface side portion of the upper door member in the holder portion. Is possible.

  In particular, according to the waterproof door device of the third aspect of the invention, when the door is opened and closed, the door rotates around the first rotation shaft and the second rotation shaft does not rotate. The second rotating shaft can be rotated when a predetermined pressure or more is applied to the door in a state where the door closes the space in the frame. Along with this, the door is pressed more strongly against the door of the frame than during normal opening and closing, so that the sealing performance between the door and the frame is improved. Therefore, even when the door cannot be opened and closed as a whole door in which the upper door member and the lower door member are connected by water pressure, the lower door member can function as a water stop plate.

  In particular, according to the waterproof door device according to the invention of claim 4, after opening only the upper door member, holding the grip portion with both hands or one hand and placing one foot on the footrest portion of the lower door member, Even if there is a certain height to the upper edge of the side door member, it is possible to get over the lower door member and escape from the space in the frame opened by the upper door member to the opposite side of the door.

The rotation of the second rotating shaft 27 is restricted during normal use, and the second rotating shaft 27 is rotated when a predetermined pressure or more is applied to the door 7. The predetermined pressure or more is a pressure that can cause the door 7 to open or close, which is difficult or difficult to move in a direction to open the frame opening S from the state in which the door opening S is closed with respect to the door 7, for example. is there.

  Thereby, as shown in FIGS. 6A and 6B, the waterproof door device 1 does not rotate the second rotating shaft 27 when the door 7 is opened and closed in daily life. When the one rotation shaft 24 rotates, the door 7 rotates about the first rotation shaft 24 as an axis. Then, as shown in FIG. 6B, the door 7 side portion and the suspension side portion of the door 7 hit only the seal member 5, and the seal member 5 is slightly contracted, so that the door 7 that is required on a daily basis. And the frame 2 can be sealed.

  Then, as shown in FIG. 6C, when the door 7 is closed and water pressure is applied to the door 7 in the direction indicated by the arrow, the connecting shaft 22 is connected to the rotating shafts 24 and 27. And the door 7 is further displaced to the seal member 5 side from the closed state of FIG. 6B, and the door 7 moves the seal member 5 to the door end side frame body 2b and the suspension side frame body 2c. The seal member 5 is pushed and contracted until it comes into contact. Thereby, the sealing performance between the door 7 and the frame body 2 is improved, and at least the lower door member 72 is prevented from being flooded from between the lower door member 72 and the frame body 2.

  By having such a hinge mechanism 21, the lower door member 72 can function as a water stop plate when the upper door member 71 is opened. For this reason, for example, if the depth of water does not reach the upper end of the lower door member 72, a person who has evacuated to the inside can open only the upper door member 71 and check the external flooding state, etc. Is possible.

  And as shown below, the waterproof door 1 of the present invention has a structure for preventing inundation caused by the door 7 being divided into the upper door member 71 and the lower door member 72, and the upper door member 71. A structure for facilitating evacuation by opening only the door is further provided.

  That is, as shown in FIGS. 2 and 7, the lower door member 72 has a door stop 22 with which the upper door member 71 abuts. The door stop 22 includes a holder portion 23 and a seal member 24.

  In this embodiment, the holder portion 23 is a plate-like vertical wall extending from the inner side panel 9b to the same plane as the inner panel 9b and extending upward from the lower connection panel 10a of the upper door member 71. A portion 23a and a plate-like upper wall portion 23b extending outward from the tip of the extending member 23a, and a U-shape with a part of the upper connecting panel 10b of the lower door member 72. There is no.

  The seal member 24 is also referred to as a waterproof rubber or packing, and is disposed from one side of the lower door member 72 to the other side, and at least the upper door member 71 is close to the seal member 24. The structure can be expanded and contracted in the direction. The seal member 24 is made of a material such as silicone rubber, ethylene propylene rubber, or chloroprene rubber. The seal member 24 is fixed by being pushed into the groove portion of the holder portion 23. In this fixed state, the seal member 24 protrudes to the outside from the upper wall portion 23 b, and the lower door member 72 is at least the seal member 24. It comes to contact | abut first.

  The upper door member 71 has a recess 25 in order to obtain a space that can be combined with the door stop 22 of the lower door member 72 within the thickness of the door 7. The recess 25 is configured by bending a portion of the lower connecting panel 10 a on the inner side of the hole where the dead bolt 204 appears and disappears to form an upright wall portion 26 that faces the door stop 22. When the upper door member 71 and the lower door member 72 are connected, the upright wall portion 26 abuts with the seal member 82 in a state where the seal member 82 is slightly expanded and contracted.

  By providing such a door stop 22 in the lower door member 72 and providing the upper door member 71 with the recess 25 combined with the door stop 22, the inner side panel 9 a of the upper door member 71 and the inner side of the lower door member 72 are provided. It is possible to bring the standing wall portion 26 of the upper door member 71 and the lower door member 72 into contact with each other with good sealing performance without forming irregularities on the panel 9b. Thus, the connection between the upper door member 71 and the lower door member 72 is released because the upright wall portion 26 of the upper door member 71 is in contact with the seal member 82 of the lower door member 72. Thus, even if the lower door member 72 is opened to the outside, it is possible to prevent the lower door member 72 from opening to the outside. Therefore, it is possible to prevent the suspicious person or the like from entering the interior by opening the lower door member 72 even though the locking device 17 is locked.

  Further, as shown in FIGS. 2, 4 and 7, the upper door member 71 is positioned above the door stop 22 in a state where the upper door member 71 and the lower door member 72 are connected. A water stop portion 27 is provided. The water stop part 27 includes a holder part 28 and a water stop rubber 29.

  The holder portion 28 includes an upright wall extending portion 26a that extends further upward than the portion facing the door stop 22, and an upper wall portion 28a that extends inward from the upper end of the upright wall extending portion 26a. The chamfered portion 28b is formed by bending the lower end of the inner side panel 9a into a U shape, and the standing wall extending portion 26a, the upper wall portion 28a, and the crushed portion 28b form an inverted U shape.

  The waterstop rubber 29 is made of a material such as silicone rubber, ethylene propylene rubber, or chloroprene rubber, and is fixed by being pushed into the groove portion of the holder portion 28. The waterproof rubber 29 protrudes toward the seal member 24 from the top of the valley fold of the crushed portion 28b and protrudes from the top of the crushed portion 28b and the upper wall portion 23b toward the inner side. Yes.
