Description

  The present invention is a structure in which a door is supported by a frame body incorporated in a part of a building or warehouse or a part of a rack for storing articles, and the door is used as a seismic element in a closed state. The present invention relates to a seismic structure with a door that gives seismic resistance to the structure.

  Structures such as buildings and storage racks have openings for people and goods to go in and out, and the frame built in the openings prevents people from entering from outside and the release of goods from inside A door is fitted for.

  In this door-attached structure, when it is assumed that the structure has undergone an earthquake, a person who remains inside the structure even if plastic deformation remains in the main body of the structure or the frame forming the opening Is considered so as to maintain a state in which the door can be opened and closed in order to escape and to carry out articles (see Patent Documents 1 to 4).

  Since conventional doors are designed as seismic doors that can be opened and closed even after earthquakes so that they do not plastically deform following the deformation of the structure or frame, the door and frame or frame A clearance for allowing relative deformation between the structures is often secured (see Patent Documents 1 and 2). However, since the clearance reduces the appearance of the door, a low friction material is interposed between the door and the frame, and the clearance is reduced by causing slippage between the two during relative deformation. (See Patent Documents 3 and 4).

Japanese Patent Laid-Open No. 11-44163 (Claim 1, paragraph 0014, FIG. 2, FIG. 3) Japanese Patent Laid-Open No. 11-210340 (paragraph 0001, paragraphs 0027 to 0046, FIG. 2) Japanese Patent Laying-Open No. 2003-27854 (Claim 1, paragraphs 0010 to 0011, FIGS. 8 and 9) JP 2003-49588 A (Claim 1, paragraphs 0016 to 0018, 0029 to 0031, FIG. 2 and FIG. 3)

  According to the methods of Patent Documents 3 and 4 in which a low friction material is interposed between the door and the frame, the door is forced from the frame when the structure or the frame is deformed during an earthquake. Because it tries to follow the deformation as a result of receiving a strong force, it can resist the horizontal force at the initial stage of the earthquake occurrence, but when the sliding with the frame occurs, the resistance force of the door The door will not always function as a resistance element against earthquakes.

  As described above, in both of the above-described methods for ensuring the clearance and the method for interposing a low friction material, the door remains sound and can be opened even when the frame body undergoes plastic deformation during an earthquake. It is designed on the premise of doing so, and there is no idea to use the door itself as a seismic element.

  In view of the above background, the present invention proposes a seismic structure with a door that actively uses the door as a seismic element.

  According to the first aspect of the present invention, in the structure in which the door is supported so as to be opened and closed by a frame body incorporated in a part of the construction surface, the door is engaged with the frame body in the peripheral portion when the door is closed. By adding the horizontal rigidity of the door to the horizontal rigidity of the structure, the door is actively used as an earthquake-resistant element, and the earthquake resistance of the structure is enhanced. The structure includes all structures that house openable doors such as buildings, warehouses, and racks.

  By engaging the door with the frame at the periphery of the door in the closed state, the integrity of the structure including the frame and the door is ensured, and the door is separated from the structure against the horizontal force during an earthquake. Can behave together. As a result, the horizontal rigidity of the door is added to the horizontal rigidity of the structure, and the horizontal rigidity of the door is added. As a result, the earthquake resistance of the structure is improved, and the door is effectively used as an earthquake resistant element of the structure.

  Specifically, the engagement state of the door and the frame is obtained by projecting a protrusion from at least one of the door and the frame to the other when the door is closed, as described in claim 2. Is engaged with the other, so that the door is kept closed against the horizontal force in the in-plane direction of the door.

  The protrusion is fixed to at least one of the door and the frame as described in claim 3, and at least one of the door and the frame as described in claim 4, In some cases, the doors are housed so as to be able to move in and out, and project when the door is closed and engage with the other. In the latter case, as shown in claim 5, there is a case where it appears and disappears in conjunction with the operation of the operation unit installed on the door, and a case where it appears and disappears in association with the opening and closing operation of the door. The protrusion may protrude from the door in the in-plane direction of the door and engage the frame body in the out-of-plane direction, or may protrude in the out-of-plane direction and engage in the in-plane direction.

  In the closed state of the door, the projections try to maintain the engaged state even when a horizontal force is applied, which is equivalent to installing a face material like a seismic wall to cover the opening in the frame. When the door is in a state and the door receives a horizontal force in the in-plane direction, the horizontal rigidity of the door is exhibited. Since the horizontal rigidity of the door functions to constrain the deformation of the opening, that is, the frame, the earthquake resistance of the structure including the frame is improved.

  In either case of claim 3 or claim 4, the protrusion is in the closed state of the door and engages with the frame or the door when the horizontal force in the in-plane direction of the door is applied. By being positioned, when the horizontal force is applied, the engagement state is established early, and the horizontal rigidity of the door is added to the structure from the initial stage when the earthquake occurs. The horizontal rigidity of the door is exhibited from the initial stage when the horizontal force is applied, as the gap (clearance) between the protrusion and the receiving portion receiving the protrusion is small. If there is a gap between the protrusion and the receiving part, the horizontal rigidity of the door will be delayed relative to the gap between the door and the frame, although the timing of the horizontal rigidity of the door will be delayed. It is not always necessary to make the gap small because it is exhibited when the phenomenon occurs.

  In the case of claim 3, wherein the protrusion is fixed to at least one of the door and the frame, the protrusion is engaged only by closing the door, and no special operation is required. Has the advantage of being simple. However, since it is necessary that the projection does not become an obstacle to the opening / closing operation of the door, the shape and the projection length of the projection may be limited.

  On the other hand, in the case of Claims 4 and 5, the door is required to be provided with a mechanical or electrical mechanism since it is brought into an engaged state by operation of the operation portion. Since the protrusion protrudes and engages after the closed state, it is possible to freely set the shape and protrusion length of the protrusion. By adjusting the shape and length, the protrusion in the engaged state It is possible to freely set the resistance force against the horizontal force received by.

  As the protrusion is positioned on the door's vertical surface and the peripheral portion of the door, the horizontal rigidity of the door can be effectively exhibited. However, if the protrusion is disposed at the four corner positions of the door as described in claim 6. Since any projection always bears the horizontal force against the horizontal force in the plane of the door, the horizontal rigidity of the door is surely exhibited.

  The horizontal rigidity of the door is added to the horizontal rigidity of the structure when the structure bears a horizontal force with the protrusions engaged. The horizontal rigidity of the door depends on the load capacity against the horizontal force of the protrusions and the door body. Since it is determined by the in-plane rigidity, if the seismic element is integrated with the door main body by, for example, installing a brace inside the door or arranging a face material as described in claim 7, the horizontal rigidity of the door is increased. As a result, the horizontal rigidity of the structure is improved. As the seismic element, a frame having a shape in which frame materials are combined in two directions is used in addition to braces and face materials, and the frame is built in or externally attached to the door.

  Moreover, if the emergency escape child door is stored in the door as described in claim 8, the plastic deformation of the frame body after the structure bears the horizontal force is large, and the door cannot be opened. In this case, it is possible to avoid a situation where a person is trapped inside the structure. In this case, for example, if the child door has a cylindrical shape or a truncated cone shape that is not easily deformed when the door receives an external force in the in-plane direction, the rigidity of the child door is added to the rigidity of the door. It is also possible to make the door function as a seismic element.

  As described above, in the present invention, the door is engaged with the frame body at the periphery of the door in the closed state, and the door is actively used as an earthquake-resistant element, so the horizontal rigidity of the door is added to the horizontal rigidity of the structure. Can improve the earthquake resistance of the structure.

  Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings.

  In the structure 2 in which the door 4 is supported so as to be freely opened and closed by the frame 3 incorporated in a part of the construction surface, the door 4 is engaged with the frame 3 in the peripheral portion when the door 4 is closed. This is an earthquake-resistant structure 1 with a door in which the horizontal rigidity of the door 4 is added to the horizontal rigidity of the structure 2. As shown in FIGS. 1 and 2, the door 4 and the frame 3 are engaged with each other when at least one protrusion 5 protruding from the other engages with the other.

  The structure 2 is a rack for storing articles as shown in FIGS. 3 to 5, and a door to a frame 3 incorporated in a part of a wall surface or a construction surface like a building or warehouse as shown in FIG. 10. Including the entire structure that supports 4, the scale is not limited. As shown in FIG. 1, the seismic structure 1 with a door has a configuration in which a protrusion 5 is fixed to at least one of the door 4 and the frame 3 and engages with the other when the door 4 is closed, and FIG. As shown in (b), at least one of the door 4 and the frame 3 is roughly divided into a form that can be retracted and retracted between the other when the door 4 is closed.

  The form of the door 4 is not limited. As shown in FIGS. 6B and 6C, in addition to the shape in which the face material is bonded to the frame assembled from the vertical rod 4a and the horizontal rod 4b, as in the flash door A door 4 having a combination of face materials is used. 4A to 4C show the front, side, and back of the structure 2, which is a rack, and FIG. 4D shows the inside of the front of the structure 2. FIG. 5A and 5B show the plane and bottom surface of the structure 2, which is a rack, and FIG. 5C shows the inside of the plane.

  FIG. 6 shows the relationship between the door 4 and the frame 3 when the protrusion 3 that engages in the in-plane direction of the door 4 is integrally attached to the door 4 with respect to the frame 3. . FIG. 6 shows the hinged door type door 4 in which a hinge 6 is connected to the hanging side of the door 4, but when a sufficient space is secured around the opening surrounded by the frame 3, the sliding door The use of a door 4 of the form is also possible. In the case of the sliding door type, the movement parallel to the surface of the door 4 may be combined with the movement in the direction perpendicular to the surface of the door 4 while facing the opening in order to securely engage the protrusion 5.

  Regardless of the hinged door type or the sliding door type, the door 4 may overlap the outdoor side of the frame body 3 as shown in FIG. In order to effectively function as a seismic element, it is better to store the door 4 in the plane of the frame 3 with the door 4 closed. In the case of the hinged door type, the door 4 may be opened to the indoor side of the structure 2 and may be opened to the outdoor side as illustrated. In either case of the hinged door type or the sliding door type, the protrusion 5 protrudes into the periphery of the door 4 as shown in FIG. 7 so that the horizontal force acting on the frame 3 can be received from the initial stage. Established.

  Specifically, when the frame 3 is about to undergo in-plane deformation by a horizontal force acting on the frame 3, it is appropriate to project the protrusion 5 at a position near the corner where the amount of deformation is greatest. Yes, in the drawing, as shown in FIG. When the door 4 having a braided shape is used, the protrusion 5 is provided near the vertical rod 4a of the upper and lower horizontal rods 4b or at the vertical position of the vertical rod 4a.

  When the projection 5 is projected on the hinged door 4, the door 4 rotates around the hinge 6, so that the projection 5 has a surface near the outer periphery of the door 4 so that the projection 5 does not collide with the frame 3. It is formed in an arcuate curved surface. Specifically, as shown in FIGS. 6A and 6B, the center of the hinge 6 is the center of curvature, and the distance to the surface of the protrusion 5 is a part of an arc having a radius (R1). Or a curved surface along the arc. The cross-sectional shape of the protrusion 5 is not limited, and the protrusion 5 is formed in an arbitrary cross section such as a circle or a square. R2 indicates the distance from the center of the hinge 6 to the edge of the door 4.

  A receiving portion 7 into which the protrusion 5 is inserted is formed in a box shape at a position corresponding to the protrusion 5 of the frame 3 that receives the protrusion 5 protruding from the door 4. The frame 3 includes a vertical frame 3a positioned on both sides of the door 4 and a horizontal frame 3b connecting the vertical frames 3a and 3a. The receiving portion 7 is formed on either the vertical frame 3a or the horizontal frame 3b. . The horizontal frame 3b is arranged above and below the vertical frame 3a in principle to stabilize the rectangular shape of the frame body 3 and constitutes a rectangular frame together with the vertical frame 3a. In some cases, the lower horizontal frame 3b may be omitted.

  In order to transmit the force from the frame 3 to the projection 5 as the deformation of the frame 3 is started by the horizontal force acting on the structure 2, the projection 5 is a receiving portion as shown in FIG. 7 is combined with the receiving portion 7 so as to be locked in the horizontal direction on the inner peripheral surface of the receiving portion 7 or to be locked with a slight clearance. As shown in FIG. 6C, which is a cross-sectional view taken along the line AA in FIG. 6A, the horizontal frame 3b is not necessarily locked to the inner peripheral surface of the receiving portion 7 in the vertical direction. With the horizontal deformation, displacement in the vertical direction is also caused, so that the vertical clearance is preferably small.

  When there is a clearance between the protrusion 5 and the inner peripheral surface of the receiving portion 7, the protrusion 5 engages with the receiving portion 7 after a relative deformation exceeding the clearance occurs between the door 4 and the frame 3, The seismic performance of the door 4 will be demonstrated.

  As shown in FIG. 7 and FIG. 9, inside or outside the door 4, a frame in which face materials, braces, or vertical members and cross members are combined into a rectangular shape to ensure resistance to the horizontal force of the door 4 itself. A seismic element 8 such as is incorporated. The face material may cover the entire surface of the door 4 or may be disposed at each corner of the door 4 as shown in FIG. Since braces bear a tensile force when a horizontal force in the plane of the frame 3 is applied, two braces are used as a set.

  FIG. 8 shows the relationship between the hinged door 4 and the frame 3 when the protrusion 5 is provided on the surface of the frame 3 on the door 4 side. Also in this case, the surface of the projection 5 near the outer periphery of the door 4 is curved at the center of the hinge 6 so that the projection 5 does not collide with the door 4 that opens and closes as shown in FIG. It is formed in a curved surface that is a part of an arc having a center and a distance (R1) to the surface of the protrusion 5 or along the arc. FIG. 8- (c) shows a cross section taken along line BB of (a). FIG. 9 shows a case where a triangular face material as the seismic element 8 of the door 4 is arranged at each corner of the door 4. The face material in this case resists horizontal force by acting to maintain the angle of the corner of the door 4 at a right angle.

  FIG. 10 shows a state in which, when the structure 2 is a building or a warehouse, the frame 3 undergoes an unexpected plastic deformation due to an earthquake and the door 4 becomes difficult to open regardless of the resistance force of the door 4. . In the present invention, since the door 4 becomes an earthquake-resistant element and bears the horizontal force at the time of the earthquake, unless the door 4 is plastically deformed, the possibility that the frame 3 is plastically deformed is low. Even if this occurs, it is possible to avoid an excessive deformation amount.

  FIG. 11 shows the door 4 with respect to the frame 3 as a means for facilitating the opening of the door 4 in case the door 4 becomes difficult to open when the door 4 is stored in the plane of the frame 3. A state is shown in which the sliding material 9 that causes the sliding is added to at least one of the inner peripheral surface of the frame 3 and the outer peripheral surface of the door 4. 12 to 14 show specific examples of FIG.

  FIG. 12 shows a case where a cylindrical roller is arranged as the sliding material 9 on each inner peripheral surface of the vertical frame 3a and the horizontal frame 3b constituting the frame body 3. The roller is housed in a recess 3c formed on the inner peripheral surface of the frame 3. The horizontal frame 3b is rotatably supported about the horizontal axis, and the vertical frame 3a is rotatably supported about the vertical axis. Is done. The roller may be constantly urged toward the door 4 by a spring so as to be able to protrude and retract from the recess 3c.

  FIG. 13 shows a case in which parts such as a round steel, a steel material having a curved surface, a synthetic resin, etc. are embedded and fixed as the sliding material 9 in the recesses 3c formed on the inner peripheral surfaces of the vertical frame 3a and the horizontal frame 3b. Show. FIG. 14 shows a case where a sheet having a small friction coefficient such as tetrafluoroethylene resin (PTFE) is bonded to the inner peripheral surfaces of the vertical frame 3a and the horizontal frame 3b. In the case of FIG. 14, it is not always necessary to form the recess 3c.

  FIG. 15 shows that the protrusion 5 is housed in the door 4 so that the protrusion 5 can be freely protruded into the frame 3 and the door 4 can be freely inserted into the door 4. 5 shows a relationship between the door 4 and the frame 3 when the protrusion 5 is inserted and immersed and the frame 3 is engaged in the in-plane direction and the out-of-plane direction of the door 4 when protruding. Here, the rotary motion in the operation unit 11 for directly operating the protrusion 5 is converted into a linear motion so that the protrusion 5 protrudes and sinks. However, there is no specific mechanism for causing the protrusion 5 to protrude. Regardless, any mechanical or electrical means may be used. As shown in FIG. 15, when the protrusion 5 protrudes in the in-plane direction of the door 4, the protrusion 5 engages in two directions, in-plane and out-of-plane of the door 4. 4 can be exerted.

  FIG. 15 shows the operation unit 11 installed on the door 4 separately from the knob and lever handle for opening and closing the door 4 and the projection 5, and the rotational movement of the operation unit 11 is converted into the linear motion of the projection 5. The two arms 12 that move, the spring 13 that pulls the two arms 12 in the direction in which the protrusions 5 are retracted, the arm 12 is connected to the operation unit 11, and the connecting member transmits the rotational motion of the operation unit 11 to the arm 12. 14 shows a case where the haunting device 10 is configured from 14.

  The protrusion 5 is connected to the tip position of the arm 12 on the side of the frame 3 so as to be rotatable about the horizontal axis. In FIG. 15, the protrusion 5 of the arm 12 is directed so that the protrusion 5 faces in the direction of appearance regardless of the angle of the arm 12. The protrusion 5 is connected to or fixed to the connecting member 12a connected to the tip. In the drawing, the arm 12 and the spring 13 are arranged above and below the operation portion 11 in order to engage the protrusion 5 with the upper and lower horizontal frames 3b. 13 may be disposed and engaged with only one of the horizontal frames 3b.

  In the case of FIG. 15, the operation unit 11 is integrated with the operation plate 11 a that is pivotally supported around the horizontal axis with respect to the door 4 and the operation plate 11 a and is exposed on the surface of the door 4. The connecting member 14 is connected to the operation plate 11a. When the door 4 is openable and closable, the protrusion 5 is immersed in the door 4 as shown in FIGS. The two arms 12 are pivotally supported by the door 4 at the intersection.

  From the immersion state of the projection 5 shown in FIG. 16, the connecting portion of the connecting member 14 with the operation plate 11a is moved downward by the clockwise rotation of the operation plate 11a shown in FIG. As shown in FIG. 15 and FIG. 17- (b), both arms 12 and 12 rotate around the pivotal support position, and the distance between the connecting portions with the connecting member 14 decreases. Projects from the door 4 as shown. The state in which the protrusion 5 protrudes and enters the receiving portion 7 is held, for example, by locking the operation portion 11, that is, the handle 11b.

  FIG. 15 shows a state in which the protrusion 5 protrudes. From the state of FIG. 15, the handle 11 b is rotated counterclockwise against the restoring force of the spring 13, and the operation plate 11 a of the connecting member 14 is The connecting portions of the arms 12 and 12 are moved upward to increase the distance between the connecting portions of the arms 12 and 12 to the connecting member 14, so that the arms 12 and 12 are opened, and the protrusion 5 is immersed in the door 4. The state in which the protrusion 5 is immersed in the door 4 is held by the restoring force of the spring 13, for example.

  As shown in FIGS. 16B and 17B, a guide sleeve 15 that guides the protrusion 5 is fixed to the position of the door 4 corresponding to the protrusion 5 to be inserted. The receiving part 7 into which the protrusion 5 enters is arranged at the position where the

  18 (a) to 18 (c) show the door 4 and the frame when the protrusion 5 is projected and retracted by converting the rotational movement of the handle 11b of the operation portion 11 into the linear movement of the rod 17 integrated with the protrusion 5. FIG. The relationship of 3 is shown. In this case, as shown in FIG. 19, the retracting device 10 is pivotally supported by the operation unit 11 and the main body of the door 4, a gear 16 that converts the rotational motion of the operation unit 11 into a linear motion and transmits it to the rod 17, 16 comprises a rod 17 connected to 16. Here, in order to convert the rotational movement of the handle 11b into the linear movement of the rod 16, a tooth profile with which the gear 16 meshes is formed on the operation plate 11a.

  Also in this case, similarly to FIG. 15, the operation unit 11 is, for example, an operation plate 11 a that is rotatably supported with respect to the door 4, and is integrated with the operation plate 11 a so as to be exposed on the surface of the door 4. As shown in FIGS. 18 and 19, a connecting member 18 connected to the rod 17 is connected to the operating plate 11a so as to move up and down in conjunction with the rotation of the operating plate 11a. Also in this example, as shown in FIG. 19, in order to engage the protrusion 5 with the horizontal frame 3 b above and below the frame body 3, the rods 17 are arranged on the upper and lower sides on both sides of the operation unit 11 to form the horizontal frame 3 b. A guide sleeve 15 is fixed to the door 4 side of the receiving portion 7.

  In the case of FIGS. 18 and 19, the operation plate 11 a is rotated by the rotation of the handle 11 b, the gear 16 is rotated accordingly, and the rod 17 is moved up and down so that the protrusion 5 is projected and retracted. For example, when the protrusion 5 protrudes and is immersed, the pin 11d fixed to the door 4 is locked in the groove 11c formed in the operation plate 11a in the direction of rotation of the operation plate 11a, and the handle 11b is locked. Is retained.

  18 and 19, in order to move the rods 17 and 17 arranged on both sides in the width direction of the door 4 up and down, the operation plate 11a is formed in a rectangular shape (track shape) with teeth on both sides in the length direction. However, if the operation plate 11a is formed in a disc shape and a tooth shape is formed on the entire circumference of the operation plate 11a as shown by a broken line in FIG. 19, the operation plate 11a rotates in any direction within the surface of the door 4. Since the rod 17 can be reciprocated, the rod 17 can be disposed, for example, in the horizontal direction as shown in FIG. 20, and the protrusion 5 can be engaged with the vertical frame 3 a of the frame 3.

  In that case, since only a single operation plate 11a is operated to rotate, a plurality of rods 17 directed in a plurality of directions can be moved and the projections 5 at the tips thereof can be engaged with the frame 3, so that the door 4 There is an advantage that the integrity of the frame 3 is enhanced, and the resistance force of the door 4 as the seismic element of the frame 3 is effectively exhibited.

  18 and 19, since the rods 17 and 17 are arranged on both sides in the width direction of the door 4, when the rod 17 protrudes, the protrusions 5 at the tip of each rod 17 protrude at four locations around the door 4. Therefore, the door 4 effectively resists as a seismic element even if the horizontal force at the time of the earthquake is borne at any of the corners of the door 4.

  18 and 19, when the door 4 bears an in-plane horizontal force, a tensile force acts on the door 4 in one of the two diagonal lines, and a compressive force acts on the other direction. However, one end of the rod 17 on either side of the operation plate 11a is subjected to one diagonal tensile force, and the other diagonal compressive force is applied to the other. Since no axial compressive force acts between them, the rod 17 does not buckle.

  In FIG. 20, as described above, the operation plate 11a is formed into a disk shape and the tooth shape is formed on the entire circumference of the operation plate 11a, and four gears 16, 16 ′ are arranged on the upper and lower sides and in the width direction, respectively. Is supported by the door 4, and in addition to the rod 17 oriented in the vertical direction in FIGS. 18 and 19, a rod 17 ′ is also arranged in the horizontal direction. A protrusion 5 'is connected to the tip of the rod 17'.

  In this case, when the vertical rod 17 is moved up and down by the rotation of the operation plate 11a, the gear 16 ′ for reciprocating the horizontal rod 17 ′ is used to reciprocate the horizontal rod 17 ′. And at least one rod 17 'is connected to each gear 16'. In FIG. 20, in order to engage the protrusions 5 ′ connected to the rod 17 ′ on both sides in the width direction of the door 4, the rod 17 ′ is connected to two upper and lower portions of one gear 16 ′. There may be only one.

  The horizontal rod 17 ′ reciprocates in the horizontal direction when the vertical rod 17 moves up and down by the rotation of the operation plate 11 a, and the protrusion 5 ′ connected to the tip protrudes and retracts toward the frame 3 side. The protrusion 5 ′ connected to the tip of the horizontal rod 17 ′ synchronizes with the protrusions and recesses of the protrusion 5 connected to the vertical rod 17, and the protrusion 5 ′ enters the receiving part 7 ′ when the protrusion 5 enters the receiving part 7. When entering, the protrusion 5 is detached from the receiving part 7 ′ when it is detached from the receiving part 7.

  In FIG. 19, the protrusion 5 connected to the tip of the rod 17 is guided by the guide sleeve 15 to the receiving portion 7 by the guide sleeve 15 in order to securely immerse the protrusion 5 in the receiving portion 7 when the rod 17 reciprocates. Then, the reciprocating direction of the rod 17 ′ and the moving direction of the protrusion 5 ′ are matched, and the link 19 is connected to the tip of the rod 17 ′ so that the protrusion 5 ′ reciprocates by the reciprocating movement of the rod 17 ′. Protrusions 5 and 5 ′ are connected to the link 19. In this case, the rod 17 ′ is connected to the vertical position with respect to the center of the gear 16 ′, and moves to the receiving portion 7 side by the rotation of the gear 16 ′ by the rotation of the operation plate 11 a toward the closing side. The link 19 is pivotally supported by the door 4 at its intermediate portion.

  FIGS. 22- (a), 23- (a), and (b) show that the structural body 2 is deformed as shown in FIG. 10 due to an earthquake and the frame 3 undergoes unexpected plastic deformation, and the door 4 is forced. When the child door 40 having a cylindrical shape, a columnar shape, or a truncated cone shape, which is highly stable against deformation due to external force, is stored in the door 4 for emergency escape, in preparation for the case where it cannot be opened as a result of undergoing a general deformation The appearance of the door 4 is shown.

  In the case of FIGS. 22 and 23, the child door 40 has a function of flowing an external force in the in-plane direction of the door 4 in the circumferential direction by being a cylinder, a columnar shape, or a truncated cone shape. Since the ability to maintain is high, there is a high possibility that even if the main body of the door 4 remains deformed, the child door 40 does not have to be deformed. Therefore, the child door 40 after the frame 3 is deformed. The opening / closing function is easily secured.

  22A shows a case where the child door 40 is arranged below the door 4, and FIGS. 23A and 23B show a case where the child door 40 is arranged in the center of the door 4. In FIG. 22- (a), FIG. 23- (a), (b), the broken line shows seismic elements 8 such as braces. Since the child door 40 is for emergency escape, it is appropriate to have a truncated cone shape whose diameter gradually increases from the outdoor side to the indoor side as shown in the figure, or vice versa, so that it can be opened from the indoor side. The door 4 is mounted so as to fit into a cylindrical or frustoconical opening 4c formed in a shape whose diameter decreases from the indoor side to the outdoor side or vice versa.

  The child door 40 is basically attached to and detached from the door 4 body by a rotational operation around the central axis from the shape. Even if the door 4 is plastically deformed especially around the opening 4c, if the child door 40 itself rotates around its central axis, it can be detached while correcting the deformation around the opening 4c. This is because the child door 40 can be attached and detached with almost no influence of deformation.

  24- (a) is a front view of the child door 40 on the indoor side, and (b) is a cross-sectional view taken along the line II. As shown here, the child door 40 has a thickness equivalent to the thickness of the main body of the door 4, and a surface plate 40 a that can be locked to the indoor side of the door 4 in a state of being overlapped with the indoor side surface of the door 4 is integrated. The handle 40b for rotating operation is integrated with the surface plate 40a. The child door 40 is basically composed of a surface plate 40a and two parts of a main body (fitting portion) which is integrated with the surface plate 40a and can be fitted into the opening 4c of the door 4 or a columnar shape or a truncated cone shape. . In FIG. 24B or the like, the surface plate 40a of the child door 40 overlaps the indoor side or outdoor side surface of the door 4 body, but the surface of the surface plate 40a is flush with the surface of the door 4 body. In this way, the child door 40 may be fitted into the opening 4c. The form of the handle 40b is not limited.

  In the case where a rotational moment more than expected is required when the child door 40 is opened, in order to secure the arm length of the handle 40b, a detachable handle 40c that is detachably attached to the handle 40b is provided as shown in FIG. The handle 40b itself is extended or connected. In the case where the child door 40 has a truncated cone shape, there is an advantage that it can be opened without requiring force if it can be rotated slightly at the time of opening.

  FIG. 24- (b) shows a spiral ridge 40d suitable for attaching and detaching the child door 40 from the indoor side by rotation, and a groove portion 4d into which the child door 40 is screwed. A mode that it formed in the internal peripheral surface of the opening 4c is shown. In this case, as shown in FIG. 25- (a), a spiral peak 40d is formed on the outer periphery of the main body (fitting portion) of the child door 40 excluding the surface plate 40a, and this corresponds to the case shown in (b). A groove 4d is formed on the inner periphery of the opening 4c of the door 4.

  In addition to the above, as shown in FIGS. 28 to 30, the child door 40 can be attached and detached from the indoor side also by rotation around the central axis and linear movement in the out-of-plane direction of the door 4. it can.

  FIG. 26-(a) shows the inner surface of the door 4 when the child door 40 is opened and closed using the handle 41 using the lever, and (b) shows the horizontal cross section of the door 4. FIGS. 27- (a) and (b) show longitudinal sections of the child door 40 shown in FIG. 26 in a closed state and an open state, respectively.

  Although the child door 40 can be supported by a hinged door, and can be directly and rotatably supported by a hinge installed in the main body of the door 4, the force is expanded and transmitted to the child door 40 in FIGS. 26 and 27. In order to open and close the handle 41 by turning and standing the handle 41, the child door 40 is fixed to the handle 41 by an intermediate bracket 43 integrated therewith, and the lower end of the handle 41 is fixed to the door 4 of the child door 40. The lower bracket 44 fixed at a lower position is pivotally supported, and the child door 40 is opened and closed by the overturning / standing operation of the handle 41 and separated from the door 4 main body when opened. The handle 41 is held by an upper bracket 42 fixed at an upper position of the child door 40 when the child door 40 is closed. The upper bracket 42 has, for example, a groove shape in which the opening side of the child door 40 is opened. When the child door 40 is closed, the upper bracket 42 is held by sandwiching the handle 41, but the holding method is not limited.

  Since the child door 40 is housed in the opening 4c formed in the door 4 main body from the indoor side or in a state of being fitted from the outdoor side, the shape of the child door 40 is a circular truncated cone shape as shown in the figure. In this case, when the child door 40 rotates around the horizontal axis on the surface of the door 4 body, when the child door 40 is to be opened, a part of the child door 40 collides with the edge of the opening 4c. there's a possibility that. On the other hand, as shown in FIG. 27, the support position (lower bracket 44) of the child door 40, that is, the position where the center of the child door 40 is spaced from the child door 40 or the surface of the main body of the door 4 protrudes. Since the line connecting each point of the child door 40 and the center of rotation becomes longer and the child door 40 is about to open, it is less likely to collide with the opening 4c. The child door 40 can be reliably opened.

  In the case of FIG. 26 and FIG. 27, a sealing material for securing airtightness is attached to at least one of the outer periphery of the child door 40 and the inner periphery of the opening 4c as necessary. In order to reduce frictional resistance with the sealing material due to the deformation of the door 4, a low friction material such as tetrafluoroethylene resin (PTFE) is interposed together with the sealing material or instead of the sealing material. It is done.

  FIGS. 28A and 28B show an example in which the child door 40 is rotated by rotating the handle 40b around the center in the axial direction and is opened as it is drawn toward the handle 40b. In this case, as shown in FIG. 29- (b), engaging portions 40e that engage with the door 4 at the time of closing are formed at a plurality of locations around the child door 40, and on the surface side around the opening 4c of the door 4 As shown to (a), the to-be-engaged part 4e with which the engaging part 40e engages is formed. The engaging portion 40e is formed on the surface plate 40a of the child door 40. The engaged portion 4e is formed in a state of protruding from the surface of the door 4 as shown in FIG. 29- (a), and is formed in a state of not protruding from the surface of the door 4 as shown in (c). In the case of (c), an insertion port 4f into which the engaging part 40e of the child door 40 is inserted is formed adjacent to the engaged part 4e.

  In the case of FIG. 28 and FIG. 29, the child door 40 maintains the closed state in a state where the engaging portion 40e is engaged with the engaged portion 4e, rotates around the axis, and the engaging portion 40e becomes the engaged portion. Open when 4e leaves. In the case of FIG. 29- (c), it is opened when the engaging portion 40e matches the insertion port 4f. As shown in FIG. 29- (a), the stability of the child door 40 in the closed state is such as a leaf spring that urges the engaging portion 40e toward the engaging portion 40e of the engaged portion 4e. This is ensured by arranging the spring 45. 30A shows a cross section taken along line JJ of FIG. 28A, and FIG. 30B shows a horizontal cross section of the door 4 as a whole.
