JP-A-2015-151717

  By the way, when rainwater, seawater, etc. are stopped by a fully closed door, a person who is indoors wants to escape to the outdoors, or a person who is outdoors wants to enter indoors to see the situation indoors. In this case, it is necessary to open the door body in a fully closed state, but it is not easy to open the door body with water pressure such as rainwater or seawater, and it is necessary to wait until rainwater or seawater is drawn. In addition, even if the door can be opened, rainwater, seawater, and the like enter the room.

  In view of this, there is a need for a device that allows rainwater, seawater, etc. to pass through the doorway without allowing rainwater, seawater, etc. to enter indoors when the door is fully closed.

  An object of the present invention is to provide a water stop device that allows passage of rain water, sea water, etc. indoors without allowing the rain water, sea water, etc. to enter indoors in a state where the water is stopped by a fully closed door. There is a place to do.

  The water stop device according to the present invention is openable and closable with respect to the doorway, and the water stop device includes a door body for preventing rainwater and the like from entering the doorway from the outdoor side. Is characterized by comprising a sub-door for passing through the doorway when the doorway is closed by the door body in order to prevent the rainwater or the like from entering.

  As mentioned above, when rainwater is stopped by a fully closed door, a person who is indoors wants to escape to the outdoors, or a person who is outdoors enters indoors to see the situation indoors. However, it is necessary to open the door body in the fully closed state, but it is not easy to open the door body with water pressure such as rain water, and it is necessary to wait until rain water or the like is drawn. In addition, even if the door can be opened, rainwater or the like intrudes indoors.

  However, as described above, the door body provided in the water stop device according to the present invention has a door body closed by the door body in order to prevent intrusion of rainwater or the like. In a state where the water is stopped by the door in the closed state, a sub door for passing through the doorway is provided.

  As a result, when a person who is indoors wants to escape to the outdoors, or when a person who is outdoors wants to enter the indoors to see the indoor situation, the fully closed door body with water pressure such as rain water is opened. There is no need to open only the sub-door.

  For this reason, while being able to pass through an entrance easily, there is no possibility that rainwater etc. may permeate indoors.

  As described above, according to the present invention, in a state where rainwater, seawater, and the like are stopped by the fully closed door body, the rainwater, seawater, etc. can pass through the doorway without entering the room.

  In the present invention, the type and structure of the door body that is configured to include (in other words, include) the sub-door may be arbitrary.

  The first example of the form and structure of the door body according to the present invention is as follows: the door body is disposed above the first door, and the second door is a sub-door; These doors can be opened and closed independently from each other with respect to the doorway, and the second door can be connected to and separated from the first door by connecting means. It is.

  In this first example, the second door, which is a sub-door, is arranged above the first door, and these first and second doors can be opened and closed independently of each other with respect to the entrance / exit. Therefore, only the sub-door can be easily opened even in a state where concentrated heavy rain, tsunami, or the like occurs, even when water pressure such as rainwater or seawater is applied to the lower part of the door body.

  Thereby, it becomes possible to pass through the doorway without allowing rainwater, seawater, etc. to enter indoors.

  In the first example, the second door can be connected to and separated from the first door by connecting means.

  For this reason, in a normal state, the second door is connected to the first door by the connecting means, and the door united with these first and second doors is opened to pass through the doorway. To. On the other hand, in the event of a heavy rain or tsunami, in order to pass through the doorway, the second door that has been connected to the first door is separated by the connecting means, and only the second door is opened. And pass through the doorway.

  In the first example of the form and structure of the door body described above, the form and structure of the connecting means may be arbitrary.

  The type and structure of the connecting means are, for example, one of the first door and the second door, an operation member for operating a latch member disposed on one of the first door and the second door, and the other. And a latch member receiving portion that receives the member. Note that the latch member receiving portion may be integrated with the door, or may be a separate member.

  Here, the type and structure of the latch member and the latch member receiving portion constituting the connecting means may be arbitrary.

  In the first example of the type and structure of the latch member and the latch member receiving portion, the latch member is disposed on the axis of the rotatable operation member provided on one of the first door and the second door, This one is rotatable together with the operation member inside, and a latch member receiving portion is provided inside the other, and the latch member is engaged (or fitted).

  Further, in the second example of the type and structure of the latch member and the latch member receiving portion, the latch member is disposed on the operation member provided on one of the first door and the second door, and to the other side. A rod-like member that protrudes and sunk into one side (in other words, a rod rod), and has a latch member receiving portion provided on the other side, and receives the rod-like member protruding to the other side. Part.

  Further, in the third example of the type and structure of the latch member and the latch member receiving portion, the latch member is disposed on the operation member provided on one of the first door and the second door, and to the other side. It is a dead bolt that protrudes and sinks into one side, and is a retractable dead bolt. A latch member receiving portion is provided on the other side, and the strike portion is a hole into which the dead bolt protruding to the other side is inserted. is there.

  In the present invention, both the first door and the second door may be hinged doors, both the first door and the second door may be sliding doors, and either the first door or the second door is There may be a sliding door and the other may be a sliding door.

  As described above, when both the first door and the second door are hinged doors, the upper end portion of the first door is provided with a door contact portion with which the lower end portion of the second door abuts. In this door contact portion, it is preferable that the lower end of the second door abuts when the second door rotates from the outdoor side to the indoor side.

  When both the first door and the second door are hinged doors, the first door can be opened and closed with respect to the entrance / exit by a biaxial hinge, and the first door closed and moved to the fully closed position is an operating member. It may be made to press-contact with the peripheral part of an entrance / exit by this operation, and it does not need to be.

  According to the former case, compared with the latter case, the water stop effect (in other words, water tightness performance) by the first door closed and moved to the fully closed position can be further improved.

  Note that the second door may or may not be openable / closable with respect to the entrance / exit by a biaxial hinge.

  In the present invention described above, when the first door and the second door have reached the fully closed position in a state of being connected by the connecting means, the outdoor side from the outdoor side due to rainwater or the like to the indoor side with respect to the second door It is preferable to provide a pressure reducing means for reducing the pressure acting on the connecting means when the pressure on the connecting means is acting.

  This is when the first door and the second door have reached the fully closed position in a state where they are connected by the connecting means, and the pressure from the outdoor side to the indoor side due to rain water or the like with respect to the second door When the pressure is applied, the pressure acts on the connecting means, so that it may be difficult to separate the second door from the first door in order to open only the second door. is there.

  For this reason, it becomes difficult to separate the second door from the first door in order to open only the second door by providing the pressure reducing means for reducing the pressure acting on the connecting means. It becomes possible to prevent this.

  In the second example of the type and structure of the door body according to the present invention, the door body can be freely opened and closed with respect to the door body main body and an opening formed in the door body main body in order to pass through the doorway. And the sub-door.

  In the second example, in the normal state, the sub door is locked to the door body main body by, for example, a locking device, and the door body in which the door body main body and the sub door are integrated is opened. And pass through the doorway. On the other hand, in the event of an emergency, such as torrential rain or tsunami, in order to pass through the doorway, the secondary door that was locked to the door body by the locking device is unlocked and only the secondary door is opened. Pass through the doorway.

  Further, in this second example, both the door body main body and the sub door may be hinged doors, both the door body main body and the sub door may be sliding doors, and either the door body main body or the sub door One of them may be a hinged door and the other may be a sliding door.

  In addition, when both the door body main body and the sub door are hinged doors, or when the door body main body is a sliding door and the sub door is a hinged door, the peripheral portion of the opening formed in the door body main body is You may make it provide the door stop part which the peripheral part of a subdoor contacts, and does not need to do it.

  In the former case, it is preferable that the door contact portion is configured such that the peripheral portion of the sub door comes into contact with the sub door when the sub door rotates from the outdoor side to the indoor side.

  This prevents the sub-door from rotating from the outdoor side to the indoor side when rain pressure or the like is applied to the sub-door from the outdoor side to the indoor side, preventing rainwater or the like from entering the indoor side. Because.

  Also, when both the door body and the sub door are hinged doors, or when the door body is a hinged door and the sub door is a sliding door, the door body can be opened and closed with respect to the entrance / exit by a biaxial hinge. The door body main body that has been closed and moved to the fully closed position may or may not be pressed against the peripheral edge of the entrance / exit by operating the operation member.

  According to the former case, compared with the latter case, the water stop effect (in other words, watertight performance) by the door body closed and moved to the fully closed position can be further improved.

  In the present invention described above, at least the lower edge, the left edge and the right edge of the peripheral edge of the doorway are watertight members for closing gaps between these portions and the door body which is in a fully closed state. May or may not be arranged.

  In addition, in the case where the type and structure of the door body is the second example described above, at least the lower edge portion, the left edge portion, and the right edge portion of the openings formed in the door body main body so as to pass through the doorway. In this case, a watertight member for closing a gap between these portions and the sub-door body in the fully closed state may or may not be disposed.

  According to the present invention, in a state where rainwater, seawater, etc. are stopped by a fully closed door, it is possible to obtain an effect that rainwater, seawater, etc. can pass through the doorway without entering the indoor.

  As can be seen from FIG. 5, the latch member receiving member 37 that forms the latch member receiving portion according to the present embodiment includes an inclined portion 37A that is inclined upward toward the outdoor space S1, and the inclined portion 37A. It has a flat portion 37B that is flat from the top, and a protruding piece portion 37C that protrudes from the tip of the flat portion 37B toward the outdoor space S1.

  Next, operation | movement of the connection means 30 for connecting the door 12 and the door 13 is demonstrated.

  7 is a front view showing the internal structure of the connecting means 30 shown in FIG. 5 with a part of the door 13 cut away, as in FIG. 6, and the door 12 and the door 13 are separated. FIG. 7 is a diagram illustrating a state in which the grip portion 32 of the handle member 31 illustrated in FIG. 6 is rotated 90 degrees counterclockwise.

  As shown in FIG. 7, when the door 12 and the door 13 are separated, the grip portion 32 of the handle member 31 constituting the connecting means 30 is in a downward (in other words, vertical) orientation. On the other hand, the latch member 35 erected on the shaft 33 of the handle member 31 is in a horizontal posture. In the state shown in FIG. 7, the handle member 31 is prevented from further rotating counterclockwise by a stop member (not shown) disposed in the space 27.

  In the state shown in FIG. 6, in order to connect the door 12 and the door 13, the handle member 31 is rotated 90 degrees in the clockwise direction.

  When the handle member 31 is rotated in the clockwise direction, the roller 36 of the latch member 35 that forms an angle of 90 degrees with the grip portion 32 of the handle member 31 contacts the latch member receiving member 37 while rolling. Will do.

  Although not shown, in this embodiment, the position in the thickness direction of the doors 12 and 13 of the latch member 35 when shown in FIG. 7 is more than the position shown in FIG. 4 and FIG. It is shifted to the indoor space S2 side by the height of the inclined portion 37A of the latch member receiving member 37 shown in FIG.

  For this reason, when the handle member 31 is rotated in the clockwise direction, the roller 36 of the latch member 35 first rolls on the inclined portion 37A of the latch member receiving member 37. When the handle member 31 is further rotated in the clockwise direction, the roller 36 of the latch member 35 rides on the flat portion 37B of the latch member receiving member 37 and then the protruding piece portion 37C of the latch member receiving member 37. The flat portion 37B rolls until it comes into contact with the.

  As shown in FIGS. 5 and 6, when the roller 36 of the latch member 35 comes into contact with the protruding piece portion 37 </ b> C of the latch member receiving member 37, the door 12 and the door 13 are connected.

  As described above, the position of the latch member 35 in the thickness direction of the doors 12 and 13 at the time shown in FIG. 7 is greater than the position shown in FIG. 4 and FIG. The height of the inclined portion 37A of the receiving member 37 is shifted to the indoor space S2 side.

  For this reason, when the roller 36 of the latch member 35 rolls on the inclined portion 37A of the latch member receiving member 37, the roller 36 presses the latch member receiving member 37 toward the indoor space S2. The pressing force becomes maximum after riding on the flat portion 37 </ b> B of the latch member receiving member 37.

  In this way, the pressing force of the roller 36 of the latch member 35 acts on the latch member receiving member 37, so that the thin portion 25 of the lower end portion 23 of the door 13 shown in FIG. 3 becomes the upper end portion 19 of the door 12. The door 12 and the door 13 are firmly connected to each other.

  The above is one of the handle members 31 constituting the connecting means 30 arranged on the left and right sides 12A on the outdoor side of the door 12 shown in FIG. 1 in order to connect the door 12 and the door 13. However, in order to connect the door 12 and the door 13, the left handle member 31 which is the other side is also turned (the right handle member 31). Unlike the member 31, an operation of rotating 90 degrees counterclockwise is performed.

  In addition, the above has been an explanation of rotating the two handle members 31 arranged on the left and right surfaces 12A of the door 12 in order to connect the door 12 and the door 13. 12 and the door 13 can also be connected by rotating the handle members 31 arranged on the left and right sides on the indoor side surface 12B of the door 12 shown in FIG.

  In the water stop device 1 according to the present embodiment, in a normal time (in other words, a normal time) other than an emergency when a heavy rain or a tsunami occurs, as shown in FIG. The door 12 and the door 13 are used in a state where they are connected to each other by the connecting means 30.

  That is, in the water stop device 1 according to the present embodiment, the doorway 2 is normally opened and closed by the door body 3 in which the door 12 and the door 13 are connected to each other by the connecting means 30.
