Description

  The present invention relates to a door device.

  In recent years, the concentration of urban functions and the effective use of underground spaces are progressing with technological progress related to flood control and architecture. Along with this, installation of buildings in areas that have been difficult or avoided in the past, undergrounding of buildings, and the like have been performed. In addition, in order to improve the cityscape, the use of underground spaces including underground underground lifelines and public transportation, and the use of waterfront areas are also progressing. In such a building, there is a tendency that the number of places requiring countermeasures against inundation increases compared to existing buildings.

  Also, due to climate change and artificial terrain changes, the necessity of inundation countermeasures has been recognized in places where there was no need or recognition of inundation countermeasures in the past. As the predictability of disasters that occur only once in hundreds of years has improved, the need for inundation countermeasures is being recognized in places where inundation countermeasures have not been taken.

  Under such circumstances, various types of water stop doors have been proposed. Broadly divided, there are undulating, sliding door, single door, and double door types. The undulating waterproof door requires a large storage space for storing the door body in the floor of the passage or the entrance. The sliding door type waterproof door requires a wide sleeve as a storage space. The door-type waterproof door only needs to be arranged near the left and right side walls by rotating the door body around the hinge, and there is no need to secure a large storage space (see, for example, Patent Document 1).

JP-A-2006-196766

  The above-described waterproof door-type waterproof door described in Patent Document 1 has a seal member attached to the door contact portion of the entire circumference of the door frame, and presses the door body against the frame body around the rotation axis of the door. Thus, when the user positions the door body in the closed position and the user rotates the gremon handle, the seal rubber comes into contact with the door body and elastically deforms, and closes to the door body and stops between the door body and the frame body. It is a watering structure. Therefore, the waterproof door of the hinged door type described in Patent Document 1 requires a plurality of gremon handles, and requires a user's operation on the glemon handles when the water stops.

  This invention is made | formed in view of the said subject, and it aims at simplifying the structure of an open door type door apparatus and simplifying operation which concerns on adjustment of the sealing property of a door apparatus.

  One aspect of the present invention is a door frame, a door receiving step provided along the entire inner circumference of the door frame, and a door frame that is openably and closably attached to the door frame via a biaxial hinge. The part facing the door receiving step is fixed to the side surface of the door receiving step that faces the door with the single-opening door having magnetism and the front magnet facing the door. And a magnet sealing material having elasticity in the opening and closing direction of the door body.

  In the door device configured as described above, a door of a single-opening type is mounted on a door frame via a biaxial hinge, and the door is opposed to a door body receiving step provided along the entire inner periphery of the door frame. The body part has magnetic adhesion. And the magnet sealing material is being fixed to the side surface which opposes the door body of the door body receiving step part with the front-end magnet part facing the door body side. Therefore, even when the door body is lightly closed, the magnet sealing material can adhere to the door body with a magnetic force, and the magnet sealing material can be sealed between the door frame and the door body. Moreover, when some force is applied to push the side surface of the door body in the opening direction, the door end side of the door body is pushed in according to the force, and the door body is offset in the closing direction. The hanging side can also be configured to move offset in the closing direction of the door body. As a result, an unprecedented door device is realized in which the airtightness between the door body and the door frame increases over the entire door body according to the force pushing the side surface in the opening direction of the door body, and the conventional waterproof door, etc. A plurality of gremon handles that are required in the door device of the present invention are eliminated, the door configuration is simplified, and a door device that does not need to perform a special operation for improving the sealing performance can be realized.

  One of the optional aspects of the present invention is that the magnet sealing material is a state in which the tip magnet portion protrudes from a groove provided along a side surface of the door body receiving step portion facing the door body. And a base device is fixed to the groove.

  In the door device configured as described above, the magnet seal material is fixed at the groove provided along the side surface facing the door body of the door receiving step, so that the fixing stability of the magnet seal material is improved. In addition, the orientation direction of the tip magnet portion of the magnet seal material is stabilized.

  One of the selective aspects of the present invention is that in the door body, a rectangular frame shape is formed in the rectangular frame region facing the protruding wall standing on the door passage space side that constitutes one side wall of the groove. This is a door device characterized in that a cushioning material is attached.

  In the door device configured as described above, the standing wall on the door passage space side that constitutes one side wall of the groove is erected toward the door body in the shape of a ridge, and this standing wall is closest to the door body A rectangular frame-shaped cushioning material larger than this rectangular frame-shaped region is attached to the rectangular frame-shaped region of the door body that is sometimes opposed. Thereby, when the standing wall is closest to the door body, the standing wall comes into contact with the cushioning material and comes into close contact, and this close contact portion also improves the sealing performance of the door device.

  One of the selective aspects of the present invention is that the magnet sealing material is elastically deformed between the tip magnet portion and the base portion according to a clamping force between the door body and the door frame. It is a door device characterized by having.

  In the door device configured as described above, since the elastic buffer portion is provided between the distal end and the proximal end of the magnet seal material, the degree of close contact between the magnet seal material and the door body increases as the force for pushing the door body increases. A structure that enhances the sealing 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 on the door frame, the door body closing direction side surface of the dead body of the door body and the door body closing direction It is a door apparatus which has a clearance gap between the inner surface of the deadbolt strike which opposes a side surface.

  In the door device configured as described above, even when the opening and closing of the door device is locked by protruding the dead bolt, the door body facing the door body closing direction side surface and the door body closing direction side surface of the door body are opposed to each other. Due to the gap provided between the inside surface of the dead bolt strike, the dead bolt can move in the dead bolt strike in the dead bolt strike toward the door body closing direction. The dead bolt does not hinder the offset movement toward the door closing direction within 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 by moving toward the door body closing direction within the gap by the pressing force applied to the side surface of the door body opening direction. The door device is characterized in that the adhesion with a magnet sealing material sandwiched between the two portions is improved.

  In the door device configured in this way, the pressing force that has been conventionally applied to the door body using the gremon handle is realized by the pressing force applied to the side surface of the door body opening direction. It is possible to provide a door device that does not require a handle and whose sealing performance changes according to the pressing force.

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

  The door device 100 is attached to the door frame 1 through a door frame 1, a door body receiving step 2 provided along the entire inner periphery of the door frame 1, and a biaxial hinge 3 so as to be openable and closable. The part facing the part 2 faces the door 4 of the door receiving step 2 with the one-side-opening type door 4 having magnetism and the tip magnet part 53 (see FIG. 9) facing the door 4. 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 closed curve or a closed curved surface formed in a structure S including a building such as a building, a house, a warehouse, or the like in a ring shape or a cylindrical shape. Switch between open and closed. The opening O is formed so that the first space S1 (for example, the flooded space) of the structure S and the second space S2 (for example, the protection space) communicate with each other. In the present embodiment, the door device 100 will be described by taking as an example 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.

  The door body 4 is configured to open to the first space S1 side, and a rotation space necessary for the door body 4 to swing and rotate when the door body 4 is opened and closed is provided in the first space S1. Accordingly, the first surface 4A facing the first space S1 side in the closed door body 4 constitutes the opening direction side surface, and the second surface 4B facing the second space S2 side in the closed door body 4 is the closing direction side surface. Configure.

  The door frame 1 is a four-side frame type frame body that is fixedly installed in 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, for example.

  Specifically, the longitudinal direction of the pair of vertical frame members 11 is oriented along the vertical direction and fixed to the end surfaces along the vertical direction of the opening O one by one, and the longitudinal direction of the pair of horizontal frame members 12 is Oriented along the horizontal direction and fixed one by one to the end surface along the horizontal direction of the opening O, and the ends of the pair of vertical frame members 11 and the ends of the pair of horizontal frame members 12 are connected together. As shown in FIG. 4, a square-shaped square frame corresponding to the shape of the opening O is formed. A caulking material or the like is filled between the door frame 1 fixed to the opening O in a fitting manner 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. A space surrounded by the four-sided frame door frame 1 is referred to as a passage space P.

  The door frame 1 is a door receiving step 2 that extends over the entire circumference of the four-side frame at a midway position in the direction of entering and exiting the opening O (hereinafter referred to as “door passing direction”) on the inner circumference of the four-side frame. Is provided. The door body receiving step 2 functions as a so-called door stopper step that receives the door 4.

  The door body receiving step portion 2 has a step shape that rises along the door passing direction from the first space S1 side toward the second space S2 side, and is stepped toward the first space S1 side that is also a rotation space of the door body 4. It extends along the longitudinal direction of the four-sided frame with the stepped side portions 21 corresponding to the above-mentioned kick-up facing each other.

  By providing the door receiving step 2, the size X2 (including both vertical and horizontal sizes) of the opening O2 on the second space S2 side across the door receiving step 2 is the opening on the first space S1. The diameter is reduced compared to the size X1 of O1 (including both vertical and horizontal sizes). The opening O <b> 1 is a size that can receive and accommodate the door surface of the door body 4, and the opening O <b> 2 is a size that is slightly smaller than the door surface of the door body 4. By providing a difference in size in this way, the step side portion 21 of the door receiving step portion 2 functions as a door step portion that directly or indirectly supports the door body 4 rotated to the closed position.

  A groove 22 extends along the four-sided frame of the door frame 1 in the step side portion 21 of the door receiving step portion 2. That is, the groove 22 has a shape having an opening 23 in the stepped side portion 21 and a recess recessed in the door passage direction from the opening 23 toward the second space S2 in a cross-sectional view. In other words, the groove 22 having an opening formed on the first space S1 side has a groove 22 in the door receiving step 2 over the entire circumference of the four-sided frame of the door frame 1 in the middle of the opening O in the door passing direction. Are provided continuously. The groove 22 is used to fix the magnet sealing material 5 in a semi-embedded shape.

  The magnet seal material 5 is a string-like member having a length substantially equal to the length of the groove 22, and is, for example, an endless string. The endless string-like magnet sealing material 5 is formed by, for example, bonding the ends of end-laced string-shaped magnet sealing material pieces prepared by cutting and separating the length of the groove 22 from a long magnet sealing material. The endless string-like magnet seal material 5 can be formed by joining with the above. More specifically, the magnet seal material pieces cut and separated to a length corresponding to each linear side of the groove 22 of the door frame 1 are joined to form the magnet seal material 5. The corner portion of the groove 22 is formed by vulcanization and adhesion in a state where the end portion of the magnet sealing material piece corresponding to one side is abutted against the side surface of the magnet sealing material piece corresponding to the other side. Of course, the endless string-like magnet seal material 5 may be formed in advance.

  The magnet sealing material 5 has a structure in which at least three layers of a fitting part 51, an elastic buffer part 52, and a tip magnet part 53 are laminated in order along the cross-sectional view and the thickness direction of the string. In the following, the length direction and the direction orthogonal to the thickness direction in the string state of the magnet sealing material 5 are referred to as the width direction, the portion near the fitting portion 51 in the thickness direction is the base 54, and the tip magnet portion in the thickness direction. A portion near 53 is referred to as a tip 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 the aspect in which the entire structure including the internal structure of the magnet seal material 5 is formed of a water-impermeable material.

  The fitting part 51 is used for fixing the magnet sealing material 5 to the groove 22. Specifically, the fitting part 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 part 51 as necessary to increase the fixing force.

  In the example shown in FIG. 8, the fitting portion 51 has protrusions 56 protruding from both side surfaces in the width direction, and the protrusions 56 are formed continuously along the length direction to form a bowl-like shape as a whole. It is a protrusion. The protrusion 56 is inclined and protrudes toward the distal end portion 55 side, and functions as a stopper for the fitting portion 51 inserted into the groove 22.

  As will be described later, the elastic buffer portion 52 is elastically deformed when the closed door body 4 is substantially offset and displaced to the second space S2 side by a pressing force such as water pressure, so that the door body 4 and the magnet sealing material 5 The water tight blockage which increases according to the pressing force by increasing the adhesive force between them is realized. In the example shown in FIG. 8, the elastic buffer portion 52 has a hollow structure filled with air. In order to improve the watertight blockage due to elastic repulsion by the elastic buffer portion 52, the groove 22 should have a depth at which a part of the elastic buffer portion 52 near the fitting portion 51 is located in the groove 22. desirable.

  The tip magnet portion 53 is built by covering the magnet M with a water-impermeable material. The magnet M has a long band shape along the length direction in the direction along the length direction of the magnet seal material 5, and one of the wide flat surfaces is disposed toward the tip portion 55.

  Both sides of the groove 22 are partitioned by side walls 24 and 25. Since the side wall 24 near the side wall of the opening O is formed integrally with the portion covering the opening O of the door frame 1, the back side of the side wall 24 is terminated by the structure S, but close to the passage space P of the opening O. The side wall 25 is constituted by a part of a standing wall 26 having a constant thickness with the back side wall facing the passage space P. The standing wall 26 has a shape in which its tip projects toward the door body 4.

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

  In the closed state of the door body 4, the rectangular frame region along the outer edge of the second surface 4 </ b> B of the door body 4 becomes a magnetic adhesion area R <b> 1 where the tip magnet portion 53 is magnetically attached, and a rectangular frame shape along the inner side of the magnetic adhesion area R <b> 1. The region is an abutting area R2 to which the elastic seal member 41 is attached. Since the tip of the standing wall 26 abuts and comes into close contact with the elastic seal member 41 in the abutting area R2, the water stopping property of water entering through the gap between the door frame 1 and the door body 4 is improved.

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

  The biaxial hinge 3 connects the first shaft part 31 having the first rotation axis A1 and the second shaft part 32 having the second rotation axis A2 with a connecting tool 33 pivotally supported by both rotation axes. This is the structure. The first shaft portion 31 and the second shaft portion 32 are arranged and connected so that the first rotation axis A1 and the second rotation axis A2 are in a positional relationship that is parallel and offset from each other. The first shaft portion 31 is fixed to the edge portion 42 of the door body 4, and the second shaft portion 32 is fixed to the door frame 1 adjacent to the edge portion 42.

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

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

  In the present embodiment, the gap 35 of the second shaft portion 32 fixed to the door frame 1 is not provided with a member that hinders the rotation of the connector 33, and the first shaft portion 31 fixed to the door body 4 is not provided. The clearance 34 is provided with a rotation restricting member 36 that restricts the rotation of the coupler 33. The rotation restricting member 36 is a member that compresses the space of the gap 34, protrudes into the rotation space used when the connecting tool 33 rotates, and can rotate the connecting tool 33 compared to the gap 34 in the state where the rotation restricting member 36 is not present. Narrow the angle.

  For example, when the rotation restricting member 36 is not provided, the connector 33 can rotate 90 ° to 180 ° or more about the first rotation axis A1. However, when the rotation restricting member 36 is provided, the connector 33 is The range in which the rotation axis A1 can be rotated is limited to 5 ° to 45 °, more preferably 5 ° to 30 °, and still more preferably 5 ° to 10 °.

  By providing the rotation restricting member 36, in the normal opening and closing of the door body 4, the first shaft portion 31 fixed to the door body 4 does not substantially function as the central 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 for opening / closing rotation of the door body 4.

  The door body 4 has a closing position for closing the opening O around the first rotation axis A1 and the second rotation axis A2 (mainly the second rotation axis A2) of the biaxial hinge 3, and an opening. It can be rotated 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 around 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 that moves not only on the door end side but also on the suspension side as a whole in the pressing direction D (substantially the same as the door closing direction) pressed against the door frame 1 (indicated by arrows in FIGS. 4 and 5). It is possible.

  The pressing direction D refers to the direction in which the door body 4 is pressed against the door frame 1. Typically, when the water pressure acts on the door body 4 from the outdoor space side, the pressing force due to the water pressure acts. It is a door body closing direction which goes to the 2nd space S2 side from the 1st space S1 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 pressurized 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.

  The door frame 1 and the door body 4 are hermetically sealed in both the non-pressure closed state and the pressure closed state. However, in the non-pressurized closed state, the pressure difference between the first space S1 and the second space S2 becomes a hermetic pressure limit when the pressure is up to a first value (for example, a water pressure of a depth of about 1 m). On the other hand, in the case of the pressure blockage state, there is a hermetic pressure limit to a second value where the differential pressure between the first space S1 and the second space S2 exceeds a first value (for example, a water pressure of about 1 m in water depth).

  Further, in the non-pressurized closed state, the biaxial hinge 3 is rotated as shown in FIG. 12B around the first rotation axis A1 relative to the first shaft portion 31 of the connector 33. It is assumed that a rotatable margin is left in the direction D1. That is, in the gap 34 of the first shaft portion 31, there is a gap between the coupling tool 33 closer to the center of the door body 4 than the first rotation axis A 1 and the rotation restricting member 36, and the non-contact state is established. When shifting from the non-pressurized closed state to the pressurized closed state, a gap is narrowed between the coupler 33 and the rotation restricting member 36 closer to the center of the door body 4 than the first rotation axis A1, and both The connecting tool 33 has a margin to rotate in the rotation direction D1 relative to the first shaft portion 31 until the two come into contact with each other.

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

  As described above, the door body 4 includes a plate-like door main body 43 whose outer dimension is slightly smaller than the inner dimension of the door frame 1, a latch bolt mechanism 44 that locks the door body 4 in the closed position, and the door body 4. And a dead bolt mechanism 45 that locks in the closed position. The door main body 43 is connected to the door frame 1 via the biaxial hinge 3. Note that the door body 4 may be provided with a door closer 46 that generates auxiliary stress with respect to the opening / closing operation of the door body 4.

  The door main body 43 has one shaft portion of the biaxial hinge 3 (hereinafter, described as an example of the first shaft portion 31) fixed to one edge portion 42 on the suspension base side. 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. Further, a latch bolt mechanism 44 and a dead bolt mechanism 45 are provided on the other edge portion 42 on the door end side of the door main body 43.

  FIG. 13 is a view for explaining the latch bolt mechanism 44. The latch bolt mechanism 44 generally includes a latch bolt 441, an urging mechanism 442, and a latch bolt operation unit 443. The latch bolt 441 is inserted through the opening 23 provided at the end portion of the door main body 43, and the tip end portion 445 can be protruded or retracted from the opening 23. The urging mechanism 442 is built in the door body 43 and urges the latch bolt 441 with a spring or the like in the protruding direction. The latch bolt operation portion 443 is configured by an operation portion 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 body 43, and an operation for projecting or retracting the latch bolt 441. It can be performed.

  The latch bolt 441 has an inclined surface 444 obtained by obliquely cutting a corner portion of the front end portion 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 the vicinity of the proximal end. When the door main body 43 is rotated from the open state to the closed state with the biaxial hinge 3 as the rotation axis, the inclined surface 444 of the tip end portion 445 contacts the door frame 1 gradually without operating the latch bolt operation portion 443. Into the door body 43.

  The door frame 1 is provided with a latch bolt strike 13 at a position facing the front end 445 of the latch bolt 441 when the door body 4 is closed. In the closed state of the door body 4, the leading end portion 445 of the latch bolt 441 protrudes and is positioned 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 / 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 forward / backward direction of the latch bolt 441. Therefore, even when the closed door body 4 is pulled in the door body opening direction, the latch bolt strike 13 and the latch bolt 441 are not released from each other, and there is no operation for pulling in the latch bolt 441 via the latch bolt operation portion 443. The door body 4 does not shift from the closed state to the open state.

  FIG. 14 is a view for explaining the dead bolt mechanism 45. The dead bolt mechanism 45 generally includes a dead bolt 451 and a dead bolt operation unit 452. The dead bolt 451 is inserted through the opening 23 provided at the end portion of the door main body 43, and the tip end portion 455 can be protruded or retracted from the opening 24. The dead bolt 451 and the latch bolt 441 advance and retract in substantially the same direction. The dead bolt operation part 452 is an operation part such as an operation piece or a cylinder lock provided on one of the first surface 4A and the second surface 4B of the door main body 43, and projects or retracts the dead bolt 451. The operation can be performed.

  The dead bolt 451 is substantially parallel to the advancing / retreating direction of the dead bolt 451 on both the first surface 4A side and the second surface 4B side of the tip portion 455, and has a substantially rectangular parallelepiped tip shape. Since the dead bolt 451 does not have an urging mechanism, the dead bolt 451 is gradually drawn into the door main body 43 when the door main body 43 is rotated from the open state to the closed state with the biaxial hinge 3 as the rotation axis. There is nothing.

  The door frame 1 is provided with a dead bolt strike 14 at a position facing the tip 445 of the dead bolt 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 end portion 445 of the dead bolt 451 protrudes and is positioned in the dead bolt strike 14.

  The side surface of the dead bolt strike 14 on the first space S1 side is substantially parallel to the advancing / retreating direction of the dead bolt 451, and the side surface of the dead bolt 451 on the first space S1 side is also substantially parallel to the advancing / retreating direction of the dead bolt 451. Therefore, even if the door body 4 is pulled in the door body opening direction, the dead bolt strike 14 and the dead bolt 451 are not unlocked, and the door is required without the operation of retracting the dead bolt 451 via the dead bolt operation portion 452. The body 4 does not transition from the closed state to the open state.

  Here, the dead bolt 451 is an offset margin greater than a certain value (hereinafter referred to as the first width W1) between the dead bolt strike 451 and the side surface 15 on the second space S2 side of the dead bolt strike 14 in the non-pressurized closed state. There is a gap R. Thereby, when the door main body 43 is pressed to the 2nd space S2 side, the dead volt | bolt 451 does not inhibit the movement to the 2nd space S2 side of the door main body 43 until the clearance gap R becomes zero. The pressure closed state is a state where the gap R between the dead bolt 451 and the side surface 15 is less than the first width W1, and the door main body 43 is pushed toward the second space S2 and is offset.

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

  When the door 4 in the open state is rotated around the biaxial hinge 3 so as to be close to the door frame 1 and the magnetized area R1 of the door 4 approaches the magnet seal material 5, the tip magnet portion of the magnet seal material 5 The door body 4 is urged toward the door frame 1 by a magnetic force attracted between the magnet 53 and the magnetized 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 further the door body 4 is placed in the frame of the door frame 1. When the force is applied so that the latch bolt 441 is pushed in, the latch bolt 441 is pulled into the door body 4 due to the interference with the door frame 1, and when the door body 4 rotates to a position where the latch bolt 441 faces the latch bolt strike 13. The latch bolt 441 protrudes 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 pushing force of the door body 4 to retract the latch bolt 441 into the door body 4. That is, when the door body 4 is sufficiently close to the door body receiving step portion 2 of the door frame 1, the magnetic force between the magnetized area R 1 of the door body 4 and the tip magnet portion 53 of the magnet seal material 5 closes the door body 4. After the magnetic adhesion area R1 and the tip magnet portion 53 are attached to each other, the traction force suppresses the backward rotation of the door body 4 to the open state. Thereby, the magnet sealing material 5 fixed to the door frame 1 is brought into close contact with the door body 4, and the gap between the door frame 1 and the door body 4 is closed with 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 standing wall 26. Further, the elastic buffering portion 52 of the magnet seal material 5 is substantially in a non-compressed state, leaving a sufficient room for contraction by receiving a compressive force. Further, as described above, when the dead bolt 451 is projected, the door body 4 is in a position where a gap R is formed between the dead bolt 451 and the dead bolt strike 14. In order to make the closed door body 4 transition to the open state, the latch bolt operating portion 443 and the dead bolt operating portion 452 are operated to retract the latch bolt 441 and the dead bolt 451 into the door body 4, and What is necessary is just to rotate the door body 4 in the door body opening direction against the pulling 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 described above, the door body 4 shifts to the pressurized closed state. FIG. 15 is a diagram illustrating a door device in a non-pressure closed state and a door device in a pressure closed state.

  At this time, the magnet seal material 5 is pushed closer to the second space S2 while the magnet seal material 5 is in close contact with the magnetized area R1. Therefore, the magnet seal material 5 formed by the door body receiving step 2 and the door body 4 is used. The clamping force is increased, the elastic buffering portion 52 of the magnet seal material 5 is compressed, the adhesion between the door body 4 and the magnet seal material 5 is increased, and the gap between the door body 4 and the door frame 1 via the magnet seal 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 reduced to a certain extent before the gap R becomes 0 because the gap is reduced to the first width W1. When the push-in amount is reached, the standing wall 26 comes into contact with the elastic seal member 41 and the sealing performance 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 hermeticity is increased in accordance with an increase in 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-open door body 4 is attached to the door frame 1 via the biaxial hinge 3, and the inner circumference of the door frame 1 is extended along the entire circumference. The part of the door body 4 facing the provided door body receiving step 2 has magnetic adhesion. And the magnet sealing material 5 is being fixed to the side surface facing the door body 4 of the door body receiving step part 2 with the front end magnet part 53 facing the door body 4 side. Therefore, even when the door body 4 is lightly closed, the magnet sealing material 5 can be attached to the door body 4 by a magnetic force so that the magnet sealing material 5 is sealed between the door frame 1 and the door body 4. Moreover, when some force is applied to press the first surface 4A of the door body 4, the door end side of the door body 4 is pushed in accordance with the force and not only the offset movement to the second space S2 side, but also the biaxial hinge 3 Thus, the suspension base side of the door body 4 can also be configured to offset move to the second space S2 side. As a result, the door device 100 that has not been provided so far is realized in which the airtightness between the door body 4 and the door frame 1 is increased according to the force of pressing the first surface 4A of the door body 4 over the entire door body 4. This eliminates the need for multiple gremon handles that are required in conventional door devices such as waterproof doors, simplifies the door structure, and realizes a door device that does not require any special operation to improve hermeticity. be able to.
