Description

  The present invention relates to a door device.

  2. Description of the Related Art In recent years, along with technological advances related to flood control, architecture, and the like, concentration of urban functions and effective use of underground spaces have been progressing. Along with this, installation of a building in an area which has been difficult or avoided in the past, undergrounding of a building, and the like have been performed. In addition, utilization of underground space including underground lifelines and public transportation, and utilization of waterfront areas are also progressing to improve cityscapes. In such a building, there is a tendency that the number of places where flood countermeasures are required is larger than in an existing building.

  In addition, due to climate change and artificial terrain change, the necessity of flood countermeasures was recognized in places where countermeasures against flooding were not necessary or were not recognized in the past. With the increased predictability of disasters that occur only once every few hundred years, the need for flood control measures is being recognized in places where flood control measures were not previously implemented.

  Under such circumstances, various types of water stop doors have been proposed. Broadly speaking, there are three types of shut-off doors: undulating, sliding, single-door, and double-door. The undulating waterproof door requires a large storage space for storing the door body in the floor of a passage or entrance. Sliding doors require wide sleeves as storage space. The hinged door type waterproof door only needs to be disposed near the left and right side walls by rotating the door body about the hinge, and it is not necessary to secure a large storage space separately (for example, see Patent Document 1).

JP-A-2006-196766

  The waterproof material of the open-door type described in Patent Document 1 described above has a seal member attached to a door stop on the entire periphery of the door frame, and presses the door body against the frame body about the pivot axis of the door. When the user rotates the glemon handle with the door positioned in the closed position as described above, the seal rubber comes into contact with the door and is elastically deformed, and the rubber sticks to the door and stops between the door and the frame. It is a structure that waters. Therefore, the waterproof door of the open-door type described in Patent Literature 1 requires a plurality of glemon handles, and a user operation on the glemon handles is required at the time of stopping water.

  The present invention has been made in view of the above problems, and has as its object to simplify the configuration of a door device of an opening door type and to simplify an operation related to adjustment of the sealing of the door device.

  One of the aspects of the present invention is a door frame, a door body receiving step provided along the entire inner periphery of the door frame, and a door frame that is attached to the door frame via a biaxial hinge so as to be openable and closable. A part facing the door body receiving step is a single-opening door body having magnetic adhesion, and a front end magnet part is fixed to a side surface of the door body receiving step facing the door body facing the door body side. And a magnet sealing material having elasticity in the opening / closing direction of the door body.

  In the door device configured as described above, the one-sided door body is mounted on the door frame via the biaxial hinge, and the door faces the door body receiving step provided along the entire inner circumference of the door frame. The body part has magnetic adhesion. A magnet sealing material is fixed to the side surface of the step receiving portion facing the door, with the tip magnet portion facing the door. Therefore, even when the door is lightly closed, the magnet seal can be magnetically attached to the door, and the space between the door frame and the door can be sealed by the magnet seal. Moreover, when any force that pushes the side surface in the opening direction of the door body is applied, not only the door tip side of the door body is pushed in according to the force and the door body is offset and moved in the closing direction of the door body, but also the door body is moved by the biaxial hinge. The suspension side can also be configured to move offset in the closing direction of the door. This realizes an unconventional door device in which the sealing property between the door body and the door frame is increased over the entire door body in accordance with the pressing force on the opening side surface of the door body. This eliminates the need for a plurality of glemon handles, which are required in the door device, simplifies the configuration of the door, and realizes a door device that does not require a special operation for improving the sealing performance.

  One of the optional aspects of the present invention is a state in which the magnet sealing material has the tip magnet portion projected into a groove provided along a side surface of the step receiving portion that faces the door body. And a base unit fixed to said groove.

  In the door device configured as described above, the base of the magnet sealing material is fixed to the groove provided along the side surface of the door receiving step that faces the door, thereby improving the fixing stability of the magnet sealing material. It becomes possible, and the orientation direction of the tip magnet portion of the magnet sealing material is stabilized.

  One of the optional aspects of the present invention is as follows. In the door body, a rectangular frame-shaped region facing a ridge-shaped standing wall on the side of a door passage space constituting one side wall of the groove is provided with a rectangular frame-shaped region. Characterized in that the cushioning material is adhered to the door device.

  In the door device configured as described above, the upright wall on the side of the door passage space, which constitutes one side wall of the groove, is erected toward the door body in the form of a ridge, and this upright wall is closest to the door body. Sometimes, a rectangular frame-shaped cushioning material that is equal to or larger than the rectangular frame-shaped region is attached to the rectangular frame-shaped region of the door body facing the door. Thus, when the upright wall comes closest to the door body, the upright wall comes into contact with the cushioning material, and the close contact portion also improves the hermeticity of the door device.

  One of the optional aspects of the present invention is that the magnet sealing material is provided between the tip magnet portion and the base portion, the elastic buffer portion being elastically deformed according to a clamping force between the door body and the door frame. It is a door apparatus characterized by having.

  In the door device configured as described above, since the elastic buffer is provided between the distal end and the base end of the magnet seal material, the stronger the force for pushing the door body, the higher the degree of close contact between the magnet seal material and the door body, and A structure that enhances the hermeticity of the device is realized.

  One of the selective aspects of the present invention is that, in a state where the latch bolt of the door body latches the door body to the door frame, the door bolt closing direction side surface of the dead bolt of the door body and the door body closing direction. This is a door device having a gap between the inner surface of the deadbolt strike facing the side surface.

  In the door device configured as described above, even when the deadbolt is projected to lock the opening and closing of the door device, the deadbolt of the door opposes the side surface of the deadbolt in the door closing direction and the side surface of the door in the closing direction. The gap provided between the deadbolt strike and the inner surface of the deadbolt strike allows the deadbolt to move in the deadbolt strike toward the door closing direction within the range of the gap, and the side of the door to the door opening direction. The deadbolt does not obstruct the offset movement toward the door closing direction in the range of the gap due to the pressing force applied to the door.

  One of the selective aspects of the present invention is that the door body is offset in the range of the gap toward the door body closing direction by a pressing force applied to a side surface of the door body opening direction, so that the door body receiving step is provided. A door device characterized in that the adhesion to a magnet sealing material sandwiched between the door unit and the unit is improved.

  In the door device configured as described above, the pressing force conventionally applied to the door using the glemon handle is realized by the pressing force applied to the side surface of the door in the opening direction. It is possible to provide a door device that does not require a handle, and whose sealing property changes according to the pressing force.

  The door device described above includes various modes such as being implemented in a state of being incorporated in another device or being implemented together with another method.

  The door device 100 is attached to the door frame 1 via a door frame 1, a door body receiving step portion 2 provided along the entire inner periphery of the door frame 1, and a two-axis hinge 3 so as to be openable and closable with at least the door body receiving step. The part facing the part 2 is a one-sided door body 4 having magnetic adhesion, and the front magnet part 53 (see FIG. 9) faces the door body 4 of the door body receiving step part 2 with the magnet body 53 facing the door body 4 side. A magnet sealing material 5 fixed to the side surface and having elasticity in the opening and closing direction of the door body 4.

  The door device 100 is installed in a gate-shaped opening O surrounded by a ring or a cylinder with a closed curve or a closed surface formed in a structure S including a building such as a building, a house, and a warehouse. Switch between open and closed. The opening O is formed so as to communicate the first space S1 (for example, a flooded space) and the second space S2 (for example, a protection space) of the structure S. In the present embodiment, a water stop door that stops water so that water or the like flowing into the first space S1 does not enter the second space S2 will be described as an example of the door device 100.

  The door 4 has a structure that opens to the first space S1 side, and a pivot space necessary for the door 4 to swing and swing when the door 4 is opened and closed is provided in the first space S1. Accordingly, the first surface 4A facing the first space S1 side of the closed door body 4 constitutes a side surface in the opening direction, and the second surface 4B facing the second space S2 side of the closed door body 4 forms a closing side surface. Is configured.

  The door frame 1 is a four-sided frame that is fitted and fixed to the opening O so as to cover the inner periphery of the opening O of the structure S. The door frame 1 can be configured by combining a plurality of frame members such as a pair of vertical frame members 11 and a pair of horizontal frame members 12.

  Specifically, the longitudinal direction of the pair of vertical frame members 11 is oriented along the vertical direction, and the longitudinal direction of the pair of horizontal frame members 12 is fixed to the respective end surfaces of the opening O along the vertical direction. Oriented along the horizontal direction and fixed to the end faces of the opening O along the horizontal direction one by one, and the ends of the pair of vertical frame members 11 and the ends of the pair of horizontal frame members 12 are connected to each other. Is formed in a square frame shape of a square shape corresponding to the shape of the opening O. A caulking material or the like is filled between the door frame 1 fixed to the opening O and each end face of the opening O, and the space between the door frame 1 and the opening O is closed in a watertight state. The space surrounded by the four-sided frame 1 will be referred to as a passage space P.

  The door frame 1 has a door body receiving step 2 extending along the entire circumference of the four-sided frame at an intermediate position in a direction of entering and exiting the opening O (hereinafter, referred to as a “door passing direction”). Is provided. The door body receiving step 2 functions as a so-called door stop step that receives the door 4.

  The door receiving step 2 has a stepped shape that rises in the door passing direction from the first space S1 side to the second space S2 side, and a staircase is provided on the first space S1 side which is also a rotation space of the door body 4. And extends along the longitudinal direction of the four-sided frame so that the step side portions 21 corresponding to the rise are opposed to each other.

  By providing the door body receiving step 2, the size X2 (including both the vertical size and the horizontal size) of the opening O2 on the second space S2 side with the door body receiving step 2 interposed therebetween is changed to the opening on the first space S1 side. The diameter is reduced as compared to the size X1 of O1 (including both the vertical size and the horizontal size). The opening O1 has a size capable of receiving and housing the door surface of the door body 4, and the opening O2 has a size slightly smaller than the door surface of the door body 4. By providing the difference in size in this way, the step side portion 21 of the door receiving step 2 functions as a door stop step that directly or indirectly supports the door 4 that has been turned to the closed position.

  A groove 22 extends along a four-sided frame of the door frame 1 at a step side portion 21 of the door body receiving step portion 2. That is, the groove 22 has a shape that has an opening 23 in the step side portion 21 and a concave portion that is recessed in the door passing direction from the opening 23 to the second space S2 when viewed in cross section. In other words, in the door receiving step 2, the groove 22 having an opening formed on the first space S1 side is provided at an intermediate position of the opening O in the door passing direction over the entire periphery of the four-sided frame of the door frame 1. Are provided continuously. The groove 22 is used for fixing the magnet sealing material 5 in a semi-buried state.

  The magnet sealing material 5 is a string-shaped member having a length substantially equal to the length of the groove 22, and is, for example, an endless string. The endless string-shaped magnet sealing material 5 is, for example, bonded to the end of a striped magnet sealing material piece created by cutting and separating a length of the groove 22 from the long magnet sealing material. To form an endless string-shaped magnet sealing material 5. More specifically, magnet sealing material pieces cut and separated into lengths corresponding to the straight sides of the groove 22 of the door frame 1 are joined to form the magnet sealing material 5. The corners of the groove 22 are formed by vulcanization bonding with the end of the magnet sealing material piece corresponding to one side abutting against the side surface of the magnet sealing material piece corresponding to the other side. Of course, it may be formed in advance in the endless string-shaped magnet sealing material 5.

  The magnet sealing material 5 has a structure in which at least three layers of a fitting portion 51, an elastic buffering portion 52, and a tip magnet portion 53 are sequentially stacked along the thickness direction of the string in a sectional view. In the following, a direction orthogonal to the length direction and the thickness direction of the string state of the magnet sealing material 5 is referred to as a width direction, a portion closer to the fitting portion 51 in the thickness direction is a base portion 54, and a tip magnet portion in the thickness direction. A portion closer to 53 will be referred to as a distal end portion 55.

  The fitting part 51, the elastic buffer part 52, and the tip magnet part 53 are integrally formed, and the entire surface is covered with a water-impermeable material such as silicone rubber. Needless to say, this does not exclude an aspect in which the entire structure including the internal structure of the magnet sealing material 5 is formed of a water-impermeable material.

  The fitting portion 51 is used for fixing the magnet sealing material 5 to the groove 22. Specifically, the fitting portion 51 is fitted and fixed in the groove 22, and a caulking material or the like is filled in the gap between the groove 22 and the fitting portion 51 as necessary to increase the fixing force.

  In the example shown in FIG. 8, the fitting portion 51 has a protrusion 56 projecting from both side surfaces in the width direction. The protrusion 56 is formed continuously along the length direction and has a pleated shape as a whole. It is a projection. The protrusion 56 is inclined and protrudes toward the distal end portion 55, and functions as a stopper for the fitting portion 51 fitted in the groove 22.

  As will be described later, when the door 4 in the closed state is substantially offset-displaced toward the second space S2 by a pressing force such as a water pressure, the elastic buffering portion 52 elastically deforms and causes the door 4 and the magnet seal material 5 to move. The tightness between them is increased to achieve a watertight closing property that increases according to the pressing force. The elastic buffer 52 has a hollow structure filled with air in the example shown in FIG. In order to improve the watertightness due to the elastic repulsion by the elastic buffer portion 52, the groove 22 should have a depth at which at least a part of the elastic buffer 52 near the fitting portion 51 is located in the groove 22. desirable.

  The tip magnet section 53 covers and incorporates the magnet M with a water-impermeable material. The magnet M is in the form of a long strip extending in the length direction along the length direction of the magnet sealing material 5, and is disposed with one of the wide flat surfaces facing the tip 55.

  Both sides of the groove 22 are defined by side walls 24 and 25. The side wall 24 near the side wall of the opening O is formed integrally with a portion covering the opening O of the door frame 1, so the back side of the side wall 24 is terminated by the structure S. Is formed by a part of an upright wall 26 having a constant thickness whose rear side wall faces the passage space P. The upright wall 26 has a shape whose tip projects toward the door body 4.

  The door body 4 has an elastic seal member 41 that is a cushioning material and also functions as a seal material attached to a position facing the tip of the standing wall 26 in the closed state. The elastic seal member 41 is attached to the door body 4 by, for example, a double-sided tape or a bond, but may be attached by various other methods. It is desirable that the elastic seal member 41 be provided integrally and continuously in the direction of the door surface of the door body 4 without interruption.

  In the closed state of the door body 4, the rectangular frame-shaped area along the outer edge of the second surface 4B of the door body 4 becomes the magnetically attached area R1 where the tip magnet 53 is magnetized, and the rectangular frame-shaped area along the inside of the magnetically attached area R1. The region becomes the abutting area R2 to which the elastic seal member 41 is attached. When the tip of the standing wall 26 abuts and adheres to the elastic seal member 41 in the abutting area R2, the water stopping performance of water that enters through the gap between the door frame 1 and the door body 4 is improved.

  The door body 4 is rotatably supported by the door frame 1 via the biaxial hinge 3 as described above. 11 is a front view of the biaxial hinge 3 and a cross-sectional view taken along line CC. FIG. 12 is an operation of the biaxial hinge 3 using a cross-sectional view taken along line DD shown in FIG. FIG.

  The biaxial hinge 3 connects a first shaft portion 31 having a first rotation axis A1 and a second shaft portion 32 having a second rotation axis A2 by connecting members 33 respectively supported by both rotation shafts. It is the structure which did. The first shaft portion 31 and the second shaft portion 32 are arranged and connected such that the first rotation axis A1 and the second rotation axis A2 are in a mutually parallel and offset positional relationship. The first shaft 31 is fixed to the edge 42 of the door body 4, and the second shaft 32 is fixed to the door frame 1 adjacent to the edge 42.

  The first shaft portion 31 rotatably supports the first rotation axis A1 above the connection tool 33 and rotates the first rotation axis A1 below the connection tool 33. It has a first lower shaft portion 312 that freely supports the shaft, and a connection portion 313 that integrally connects the first upper shaft portion 311 and the first lower shaft portion 312 through the side of the connector 33. A gap 34 is provided between the connection portion 313 and the connection tool 33 so that the connection tool 33 can rotate about the first rotation axis A1 by 90 ° to 180 ° or more.

  Similarly, the second shaft portion 32 includes a second upper shaft portion 321 that rotatably supports the second rotating shaft A2 above the connecting member 33 and a second rotating shaft A2 below the connecting member 33. A second lower shaft portion 322 that rotatably supports the second shaft portion 322 and a connecting portion 323 that integrally connects the second upper shaft portion 321 and the second lower shaft portion 322 through the side of the connecting tool 33. . A gap 35 is provided between the connecting portion 323 and the connecting member 33 so that the connecting member 33 can rotate about the second rotation axis A2 by 90 ° to 180 ° or more.

  In the present embodiment, the gap 35 between the second shaft portion 32 fixed to the door frame 1 does not include a member that inhibits rotation of the connecting member 33, and the gap 35 of the first shaft portion 31 fixed to the door body 4 is not provided. The gap 34 is provided with a rotation restricting member 36 for restricting the rotation of the connecting member 33. The rotation restricting member 36 is a member that presses the space of the gap 34, protrudes into a rotation space used when rotating the connecting member 33, and allows the connecting member 33 to rotate more than the gap 34 without the rotation restricting member 36. Narrow the angle.

  For example, in a state where the rotation restricting member 36 is not provided, the connecting member 33 can rotate by 90 ° to 180 ° or more around the first rotation axis A1. The range of rotation about one rotation axis A1 is limited to 5 ° to 45 °, more preferably 5 ° to 30 °, and further preferably 5 ° to 10 °.

  By providing the rotation restricting member 36, when the door body 4 is normally opened and closed, the first shaft portion 31 fixed to the door body 4 hardly functions as a center axis of the opening and closing rotation of the door body 4, The second shaft portion 32 fixed to the frame 1 functions as a central axis of the opening and closing rotation of the door body 4.

  The door body 4 includes a closing position at which the opening O is closed around a first rotation axis A1 and a second rotation axis A2 (mainly, a second rotation axis A2) of the biaxial hinge 3 as a rotation center, and an opening. It becomes rotatable with respect to the door frame 1 over an open position where O is opened.

  Since the door body 4 is rotatably supported by the door frame 1 about the first rotation axis A1 and the second rotation axis A2 of the biaxial hinge 3, the door body 4 is in the closed position. Offset movement in which not only the door tip side but also the hanging side move as a whole in the pressing direction D pressed against the door frame 1 (substantially the same as the door closing direction) (indicated by an arrow in FIGS. 4 and 5). It is possible.

  The pressing direction D refers to a direction in which the door body 4 is pressed against the door frame 1, and typically, a direction in which a pressing force due to the water pressure acts on the door body 4 when the water pressure acts from the outdoor space side. And the door body closing direction from the first space S1 side to the second space S2 side.

  The state of the door body 4 defined by the relative position with respect to the door frame 1 includes an open state in which the passage space P of the door frame 1 is opened (not closed) and a closed state in which the passage space P of the door frame 1 is closed. There is. The closed state further includes a non-pressurized closed state in which the door body 4 is not pressed in the pressing direction D, and a pressurized closed state in which the door body 4 is pressed in the pressing direction D. is there.

  In both the non-pressurized closed state and the pressurized closed state, the space between the door frame 1 and the door body 4 is sealed. However, in the case of the non-pressurized closed state, when the pressure difference between the first space S1 and the second space S2 is about the first value (for example, the water pressure at a water depth of about 1 m), the pressure resistance of the hermetic seal is reached. On the other hand, in the case of the pressurized closed state, the sealed pressure resistance limit is set to a second value where the pressure difference between the first space S1 and the second space S2 exceeds a first value (for example, a water pressure at a water depth of about 1 m).

  In the non-pressurized closed state, the biaxial hinge 3 rotates the connecting member 33 relative to the first shaft portion 31 about the first rotation axis A1 as shown in FIG. It is assumed that a margin rotatable in the direction D1 is left. That is, in the gap 34 of the first shaft portion 31, there is a gap between the coupling member 33 closer to the center of the door body 4 than the first rotation axis A1 and the rotation regulating member 36, and the non-contact state is established. When shifting from the non-pressurized closing state to the pressurized closing state, the gap between the rotation restricting member 36 and the connecting member 33 closer to the center of the door body 4 than the first rotation axis A1 is narrowed. The connector 33 has a margin for rotating in the rotation direction D1 relative to the first shaft portion 31 until the contact is made.

  Hereinafter, the difference between the non-pressurized closed state and the pressurized closed state will be mainly described in detail.

  The door body 4 includes a plate-shaped door body 43 having an outer dimension slightly smaller than the inner dimension of the door frame 1 as described above, a latch bolt mechanism 44 for locking the door body 4 in a closed position, and the door body 4. And a deadbolt mechanism 45 that locks in the closed position. The door body 43 is connected to the door frame 1 via the biaxial hinge 3. Note that the door 4 may be provided with a door closer 46 that generates an auxiliary stress for the opening and closing operation of the door 4.

  In the door body 43, one shaft portion of the biaxial hinge 3 (hereinafter, the case of the first shaft portion 31 will be described as an example) is fixed to one edge portion 42 on the hanging side, and the first shaft portion is fixed to the first shaft portion. The other shaft portion of the biaxial hinge 3 connected to the shaft portion 31 (hereinafter, the case of the second shaft portion 32 will be described as an example) is fixed to the door frame 1 adjacent to the edge portion 42. In addition, a latch bolt mechanism 44 and a dead bolt mechanism 45 are provided on the other edge 42 on the door tip side of the door body 43.

  FIG. 13 is a diagram illustrating the latch bolt mechanism 44. The latch bolt mechanism 44 generally includes a latch bolt 441, a biasing mechanism 442, and a latch bolt operation unit 443. The latch bolt 441 is inserted through the opening 23 provided at the end of the door body 43, and the tip 445 can be protruded or retracted from the opening 23. The urging mechanism 442 is built in the door main body 43 and urges the latch bolt 441 in a projecting direction with a spring or the like. The latch bolt operation unit 443 is configured by an operation unit such as a handle or a knob provided on at least one of the first surface 4A and the second surface 4B of the door main body 43, and an operation for causing the latch bolt 441 to protrude or retract. It can be performed.

  The latch bolt 441 has an inclined surface 444 obtained by diagonally cutting a corner of the tip 445 on the second surface 4B side. The inclined surface 444 extends from the distal end of the latch bolt 441 protruding from the opening 23 to near the base end. When the door main body 43 is rotated from the open state to the closed state using the biaxial hinge 3 as a rotation axis, the inclined surface 444 of the distal end portion 445 comes into contact with the door frame 1 without operating the latch bolt operation part 443, and gradually. And into the door main body 43.

  The door frame 1 is provided with a latch bolt strike 13 at a position facing the tip 445 of the latch bolt 441 when the door body 4 is closed. When the door 4 is closed, the tip 445 of the latch bolt 441 projects and is located in the latch bolt strike 13.

  The side surface of the latch bolt strike 13 on the first space S1 side is substantially parallel to the advancing and retreating direction of the latch bolt 441 (substantially parallel to the first surface 4A and the second surface 4B of the door body 4). The side surface on the space S1 side is also substantially parallel to the advancing and retreating direction of the latch bolt 441. Therefore, even if the door 4 in the closed state is pulled in the door opening direction, the latch bolt strike 13 and the latch bolt 441 are not locked, and there is no operation for retracting the latch bolt 441 via the latch bolt operating section 443. The door 4 does not shift from the closed state to the open state.

  FIG. 14 is a diagram illustrating the deadbolt mechanism 45. The deadbolt mechanism 45 generally includes a deadbolt 451 and a deadbolt operation unit 452. The dead bolt 451 is inserted through the opening 23 provided at the end of the door body 43, and the tip 455 can be protruded or retracted from the opening 24. The forward and backward directions of the dead bolt 451 and the latch bolt 441 are substantially the same. The deadbolt operating portion 452 is an operating portion such as an operating piece or a cylinder lock provided on one of the first surface 4A and the second surface 4B of the door body 43, and makes the deadbolt 451 protrude or retract. Operations can be performed.

  The dead bolt 451 has a substantially rectangular parallelepiped tip shape in which both the first surface 4A side and the second surface 4B side of the tip portion 455 are substantially parallel to the moving direction of the dead bolt 451. Since the dead bolt 451 has no urging mechanism, the dead bolt 451 is gradually pulled into the door main body 43 when the door main body 43 is rotated from the open state to the closed state about the biaxial hinge 3 as a rotation axis. There is nothing.

  The door frame 1 is provided with a deadbolt strike 14 at a position facing the tip 445 of the deadbolt 451 when the door body 4 is closed. When the dead bolt operating portion 452 is operated to cause the dead bolt 451 to protrude, the tip portion 445 of the dead bolt 451 protrudes and is located in the dead bolt strike 14.

  The side surface of the deadbolt strike 14 on the first space S1 side is substantially parallel to the moving direction of the dead bolt 451, and the side surface of the deadbolt 451 on the first space S1 side is also substantially parallel to the moving direction of the deadbolt 451. Therefore, even if the door body 4 is pulled in the door body opening direction, the lock between the dead bolt strike 14 and the dead bolt 451 is not released, and the door is not retracted through the dead bolt operation part 452 to operate the door. The body 4 does not transition from the closed state to the open state.

  Here, the dead bolt 451 has a fixed value (hereinafter, referred to as a first width W1) or more as an offset margin between the dead bolt strike 14 and the side surface 15 of the dead bolt strike 14 on the second space S2 side in the non-pressurized closed state. It has a gap R. Thus, when the door body 43 is pressed toward the second space S2, the dead bolt 451 does not hinder the movement of the door body 43 toward the second space S2 until the gap R becomes zero. The pressure-closed state is a state in which the gap R between the dead bolt 451 and the side surface 15 is smaller than the first width W1, and the door body 43 is pushed toward the second space S2 and is offset.

  The door device 100 described above operates as follows between the open state and the closed state during normal use in which pressing force such as water pressure is not applied to the first surface 4A.

  When the door 4 in the open state is rotated about the biaxial hinge 3 so as to approach the door frame 1, and the magnetically attached area R 1 of the door 4 approaches the magnet sealing material 5, the tip magnet portion of the magnet sealing material 5 The door body 4 is urged toward the door frame 1 by a magnetic force attracting between 53 and the magnetically attached area R1 of the door body 4.

  When the leading end side of the rotation of the door body 4 enters the passage space P surrounded by the door frame 1, the tip inclined portion of the latch bolt 441 comes into contact with the door frame 1, and the door body 4 is further moved into the door frame 1. When a force is applied so as to push the latch bolt 441 into the door frame 1, the latch bolt 441 retracts into the door body 4 due to interference with the door frame 1, and when the latch bolt 441 turns to a position facing the latch bolt strike 13, the door body 4 rotates. , The latch bolt 441 projects into the latch bolt strike 13 by the biasing mechanism 442.

  At this time, the magnetic force of the magnet sealing material 5 acts as a force that assists the force that pushes the door 4 to retract the latch bolt 441 into the door 4. That is, when the door 4 is sufficiently close to the door receiving step 2 of the door frame 1, the magnetic force between the magnetically attached area R1 of the door 4 and the tip magnet 53 of the magnet sealing material 5 closes the door 4. After the magnetic attachment area R <b> 1 and the tip magnet 53 are attached to each other, the traction force is a traction force for suppressing the return rotation of the door 4 to the open state. As a result, the magnet sealing material 5 fixed to the door frame 1 comes into close contact with the door body 4, and a gap between the door frame 1 and the door body 4 is closed by the magnet sealing material 5.

  At this time, the elastic seal member 41 provided on the second surface 4 </ b> B of the door body 4 is not in contact with the tip of the upright wall 26. In addition, the elastic buffer portion 52 of the magnet sealing material 5 is in a substantially non-compressed state, and is in a state where there is enough room to contract by receiving a compressive force. Further, as described above, when the dead bolt 451 is projected, the door body 4 is at a position where a gap R is formed between the dead bolt 451 and the dead bolt strike 14. In order to cause the door 4 in the closed state to transition to the open state, the latch bolt 441 and the dead bolt 451 are operated to retract the latch bolt 441 and the dead bolt 451 into the door 4, and the magnet What is necessary is just to rotate the door body 4 in the door opening direction against the traction force of the sealing material 5.

  On the other hand, when a pressing force such as water pressure is applied to the first surface 4A of the door device 100 in the non-pressurized closed state, the door body 4 shifts to the pressurized closed state. FIG. 15 is a diagram illustrating a door device in a non-pressurized closed state and a door device in a pressurized closed state.

  At this time, since the door body 4 is further pushed into the second space S2 side while the magnet sealing material 5 is in close contact with the magnetic attachment area R1 by magnetic force, the magnet sealing material 5 formed by the door body receiving step portion 2 and the door body 4 is formed. The clamping force is increased, the elastic buffer 52 of the magnet sealing material 5 is compressed, the adhesion between the door body 4 and the magnet sealing material 5 is increased, and the space between the door body 4 and the door frame 1 via the magnet sealing material 5 is increased. Sealability is improved.

  At this time, if the dead bolt 451 is protruded, the gap on the second space S2 side of the dead bolt 451 in the dead bolt strike 14 is smaller than the first width W1, and the gap before the gap R becomes zero is reduced to some extent. The vertical wall 26 abuts against the elastic seal member 41 at the point when the pushing amount is reached, and the sealing between the door body 4 and the door frame 1 is improved. As described above, the door device 100 according to the present embodiment has a structure in which the hermeticity increases in accordance with an increase in the pressure applied to the first surface 4A of the door body 4.

  As described above, in the door device 100 according to the present embodiment, the single-opening door body 4 is mounted on the door frame 1 via the biaxial hinge 3, and along the entire inner circumference of the door frame 1. The portion of the door body 4 facing the provided door body receiving step 2 has magnetic adhesion. A magnet sealing material 5 is fixed to the side surface of the door receiving step 2 facing the door 4 with the tip magnet 53 facing the door 4. Therefore, even when the door 4 is lightly closed, the magnet sealing material 5 is stuck to the door 4 by magnetic force, and the space between the door frame 1 and the door 4 can be sealed. In addition, when any force that pushes the first surface 4A of the door body 4 is applied, not only the door tip side of the door body 4 is pushed in accordance with the force and offset-moved to the second space S2 side, but also the biaxial hinge 3 Thereby, the suspension side of the door body 4 can also be configured to be offset-moved to the second space S2 side. Thereby, the door device 100 which is not conventional can be realized in which the sealing property between the door body 4 and the door frame 1 increases over the entirety of the door body 4 according to the force pressing the first surface 4A of the door body 4. This eliminates the need for a plurality of glemon handles, which are required in conventional door devices such as waterproof doors, simplifies the configuration of the door, and realizes a door device that does not require any special operation to improve sealing performance. be able to.
