Description

[Technical Field]

[0001] The present invention relates to a door opening / closing mechanism and a private room. [Background Art]

[0002] For example, Patent Document 1 (Japanese Patent No. 6674505) discloses a shielding structure for an outward-opening door for emergencies that can reliably shield the gap between a door and a door frame.

[0003] In the shielding structure for an outward-opening door for emergencies described in Patent Document 1, the door is attached to a door frame so as to be able to open inward in normal times and open outward in emergencies, and the shielding structure for an outward-opening door for emergencies is for shielding the gap between the door end of the door and the door end stile of the door frame. The shielding structure includes a movable part that has a recess and is rotatably supported in a horizontal plane, and a fixed part that has a protrusion that fits into the recess. The movable part is attached to one of the door end and the door end stile, and the fixed part is attached to the other. When the door is closed, and the outer end of the movable part is moved in the direction in which the gap widens by the action of an external force, the inner end of the movable part moves in the direction to close the gap.

[0004] Patent Document 2 (Japanese Unexamined Patent Publication No. 2013-124485) discloses an opening / closing structure for a door of a toilet booth or a shower booth, which is configured to be extremely safe as a whole. When opening or closing the door, even if a finger is pinched between the partition panel and the door edge, such as at a hinge portion between the hanging-side partition panel and the door edge, or in the gap between the leading-end-side partition panel and the door edge, serious injury is prevented.

[0005] The opening and closing structure for a toilet booth or shower booth door described in Patent Document 2 is an opening and closing structure for a toilet booth or shower booth door in which a side wall edge member and a door edge member are attached to the door hinge portion and the door edge portion, respectively, characterized in that, at the door hinge portion and the door edge portion, either one or both of the opposing side wall edge member and door edge member are formed from an elastic material continuously from the upper end to the lower end of the side wall or door, and a cavity is formed inside it that extends from the upper end to the lower end, and the structure is configured to be elastically deformable by external force.

[0006] Patent document 3 (Japanese Patent Publication No. 2022-14144) discloses a door stopper device that can smoothly and quickly open an inward-opening door outward in an emergency.

[0007] The door stop device described in Patent Document 3 is a door stop device that allows a door rotatably mounted on one vertical frame portion of a door frame defining the entrance to a booth to rotate into the booth from a closed position that closes the entrance, but prevents it from rotating out of the booth, and comprises a base fixed to the upper frame portion or the other vertical frame portion of the door frame, a door stop member connected to the base so as to be rotatable between a restricting position that interferes with the rotation trajectory of the door and a retracted position that does not interfere with the rotation trajectory of the door, and a locking mechanism that locks the door stop member to the base in the restricting position and has a release operation portion for releasing this locked state.

[0008] Patent Document 4 (Japanese Patent Publication No. 2004-346565) discloses a door stop device equipped with a movable door stop member that facilitates the door stop release operation and enables a quick door stop release operation.

[0009] The door stop device described in Patent Document 4 is a door stop device that is attached to an inward-opening door, and comprises a movable door stop member that can move between an outward-opening restricting position that restricts the outward opening of the door and an outward-opening permitting position that allows the door to open outward, characterized in that under normal circumstances the movable door stop member is held in the outward-opening restricting position, and in an emergency the movable door stop member is moved to the outward-opening permitting position in response to the operation of a push button facing the outside through a through-hole in the door.

[0010] Patent Document 5 (Japanese Patent Publication No. 2014-141871) discloses an emergency unlocking mechanism, a hinged door device, and a private room unit that can easily open an inward-opening door outward in an emergency and are resistant to damage.

[0011] The emergency unlocking mechanism described in Patent Document 5 comprises a door edge fixed to the door edge of a hinged door attached to a panel forming an entrance to a room, a flexible pin held on the door edge so as to rotate with respect to the door edge about an axis parallel to the rotation center of the hinged door relative to the panel, and a locking part attached to the door edge side of the hinged door. The flexible pin has a rotating shaft and a wing portion that protrudes radially outward from the rotating shaft and is provided on the rotating shaft to cover the gap between the door edge of the hinged door and the panel. The locking part has a lock body provided on the hinged door and a receiving member provided on the panel that engages with the lock body. The lock body has a normal state in which it can engage with the receiving member and an emergency unlocking state in which it releases the engagement with the receiving member. In the normal state, the movement of the hinged door is restricted to inward opening only by holding the flexible pin so as to contact the surface of the outer surface of the panel that faces inward. In the emergency unlocking state, the movement of the hinged door is restricted to double opening by allowing the flexible pin to move to a position where the wing portion and the panel do not come into contact.

[0012] Patent document 6 (Japanese Patent Publication No. 2003-321961) discloses an internal unlocking device for a door structure that allows for emergency escape even from inside the door, such as from inside a door with a flat handle or lever handle.

[0013] The internal unlocking device for a door structure described in Patent Document 6 is a door structure in which a latch is attached to or detached from a fixed body such as a housing, frame, or support column by operating a handle on the outside of the door. The device consists of an operating plate pivotally attached by an operating pin to a base connected to the handle on the inside of the door, and a latch that is rotatable by an action pin provided on the inside of the door via the operating plate and a spring. In normal conditions, by operating the handle, the operating plate is brought into contact with the latch by the tensile force of the spring, and the base, the operating plate and base are rotated to attach or detach the latch to the body. In an emergency, by pressing a part of the operating plate away from the operating pin, the operating plate is released from contact with the latch, and the latch is detached from the body by the spring, allowing the door to open inward.

[0014] [Patent Document 1] Patent No. 6674505 [Patent Document 2] Japanese Patent Publication No. 2013-124485 [Patent Document 3] Japanese Patent Publication No. 2022-14144 [Patent Document 4] Japanese Patent Publication No. 2004-346565 [Patent Document 5] Japanese Patent Publication No. 2014-141871 [Patent Document 6] Japanese Patent Publication No. 2003-321961 [Overview of the project] [Problems that the invention aims to solve]

[0015] Generally, in private rooms such as bathrooms, toilets, and bedrooms, hinged doors that open inward, especially doors with door sills, are used to avoid obstructing the space on the corridor side. These inward-opening hinged doors have the advantage of preventing collisions even if someone is present on the corridor side outside the door. They also offer the benefit of saving space in private rooms for both men and women.

[0016] Furthermore, in recent years, a problem has arisen where, if there is an obstacle or a person lying near a hinged door that is meant to be opened inward in an emergency, the door may hit the obstacle or person and be unable to open completely. For example, it is common practice to design doors to open outwards in emergencies, anticipating that a occupant of a private room might lean against the door and fall. However, a problem arises when a door stopper is located in the path of the door opening outwards, preventing it from opening outwards in an emergency.

[0017] The shielding structure for an emergency outward-opening door described in Patent Document 1 has the advantage of preventing others from widening the gap from the outside and peeking inside. However, because it uses an elastic material, it requires maintenance every few decades. Furthermore, the opening and closing structure for toilet booth or shower booth doors described in Patent Document 2, the door stopper device described in Patent Document 3, the door stopper device described in Patent Document 4, the emergency unlocking mechanism described in Patent Document 5, and the internal unlocking device for door structures described in Patent Document 6 do not provide any means of relief in cases where there are obstacles or other obstructions inside the cubicle that prevent the door from opening.

[0018] The objective of the present invention is to provide a door opening / closing mechanism and a private room that allows opening in one direction during normal use and in the other direction in an emergency. Another object of the present invention is to provide a door opening and closing mechanism and a private room that can open inward when in use and outward in an emergency. [Means for solving the problem]

[0019] (1) According to one aspect, a door opening and closing mechanism comprises: a door for allowing entry and exit; a door hinge provided on an inner side, pivotally supporting the opening and closing of the door and enabling the door to rotate inward; an inner frame having a door stop formed on at least a side of the door; an outer frame provided on the upper side and the side of the door other than the lower side of the door; a hinge on one side provided on the one side where the door hinge is provided for connecting the inner frame and the outer frame; a hinge on the other side provided on the other side in the lateral direction for connecting the inner frame and the outer frame; and an other-side releasing portion for releasing the rotation of the hinge on the other side, wherein the other-side releasing portion rotates the hinge on the other side to rotate a part of the inner frame outward, thereby enabling the door to rotate outward via the hinge on the one side.

[0020] In this case, the other-side releasing portion rotates the hinge on the other side to rotate a part of the inner frame outward, so that the door can be rotated outward via the hinge on the one side. That is, during normal use, the door can be rotated in one direction (inward), and in an emergency or urgent situation, the other-side releasing portion allows the door to be rotated in the other direction (outward). As a result, a user of the door opening and closing mechanism can remove obstacles on the other side of the door and move through. That is, for a door that can only rotate in one direction (inward), there has been a problem that obstacles or persons to be rescued block the door, and since the door can only open inward, the obstacles cannot be removed or the persons to be rescued cannot be rescued. In contrast, since the door can also be rotated in the other direction (outward), a user can easily move through in an emergency, remove obstacles, and rescue persons to be rescued.

[0021] (2) A door opening and closing mechanism according to a second aspect of the present invention is the door opening and closing mechanism according to the one aspect of the present invention, wherein the inner frame consists of a one-side frame on the one side and an other-side frame on the other side, and may further comprise a one-side releasing portion for releasing the rotation of the hinge on the one side.

[0022] In this case, since the inner frame consists of one frame and the other frame, the door can be opened outwards in a large space by releasing both the one frame and the other frame. As a result, in an emergency, users can move easily, obstacles can be removed, and people in need of rescue can be assisted. Furthermore, since it consists of one frame and the other frame, the strength of the inner frame can be increased. In addition, the inner frame can be easily released by providing the openings on one side and the other side with bolts or bolts with a partially threaded shape in two or four places on the top, bottom, left, and right sides.

[0023] (3) The door opening and closing mechanism according to the third invention is a door opening and closing mechanism according to one aspect of the invention, wherein the inner frame may consist of two frames, one on one side and the upper side, and the other frame on the other side, or three frames, one on one side, the other side, and the upper side, all of which are integrated.

[0024] In this case, the door can be opened outwards by rotating the other frame. As a result, the person in need of rescue can be rescued smoothly. In this case, since the two frames, one side and the upper side, are integrated and open together with the door, there is no need to provide an opening on one side, thus reducing the number of components. Furthermore, the three-sided frame can be opened outwards along with the door. As a result, in an emergency, users can easily move around, remove obstacles, and rescue those in need. In this case, opening the three-sided frame together with the door eliminates the need for a separate opening on one side, thus reducing the number of components.

[0025] (4) The door opening and closing mechanism according to the fourth invention is a door opening and closing mechanism according to one aspect of the invention, wherein the other opening part for rotational release may include at least one of a locking mechanism, a locking mechanism, a bolt and nut, a screw structure, a pin and a pin receiving structure.

[0026] In this case, the other side opening includes at least one of a locking mechanism, a locking mechanism, a bolt and nut, a screw structure, a pin and a pin receiving structure, so that it can be reliably opened outwards in an emergency.

[0027] (5) The frame structure according to the fifth invention is a door opening and closing mechanism according to any of the fourth inventions in one aspect, and includes a protruding member built into the door, a contact member provided on the outer frame, and a contact member that contacts the contact member, wherein the protruding member provided inside the door may protrude when the contact member is pressed by the contact member.

[0028] In this case, the contact member is pressed by the abutting member, causing the protruding member installed inside the door to protrude, thereby closing the gap between the door and the floor, and the gap between the door and the ceiling.

[0029] (6) The door opening and closing mechanism according to the sixth invention is the door opening and closing mechanism according to the fifth invention, wherein the protruding members may be provided on at least one, more, or all of the upper, both sides, or lower sides of the door.

[0030] In this case, since the protruding members are provided on at least one, more, or all of the upper, side, and lower parts of the door, sound insulation, smoke protection, etc., can be improved. Furthermore, the protruding member may be provided only in the vertical direction of the door, and the left and right sides of the door may be addressed by providing a shielding portion.

[0031] (7) The door opening and closing mechanism according to the other invention includes a door for entering and exiting, a protruding member built into the door, a door hinge provided on the inside of the door that pivotally supports the opening and closing of the door and allows the door to rotate inward, an inner frame with a door stop formed on at least the side of the door, and an outer frame provided on the upper and / or side of the door other than the bottom, wherein the protruding member provided inside the door is pushed out when a contact member interlocked with the protruding member and a contact member attached to the outer frame or the outer frame come into contact and press against each other.

[0032] In this case, since the protruding members are provided on at least one, more, or all of the upper, side, and lower parts of the door, sound insulation or smoke protection can be improved. Furthermore, the protruding member may be provided only in the vertical direction of the door, and the left and right sides of the door may be addressed by providing a shielding portion. As a result, when the door is closed, the protruding member extends to enhance sound insulation or smoke protection, and when the door is opened or in an emergency, the protruding member is retracted to facilitate smooth movement in the opening direction of the door.

[0033] (8) Furthermore, the individual rooms related to other phases are equipped with door opening and closing mechanisms that conform to the same phase.

[0034] In this case, the other opening mechanism rotates the hinge on the other side, causing a portion of the inner frame to rotate outward, allowing the door to be rotated outward using the hinge on one side. In other words, under normal use, the door can be rotated inward, and in emergencies or emergencies, the other opening mechanism allows the door to be rotated outward. As a result, in emergencies, users can move easily, obstacles can be removed, and those in need of rescue can be helped. In other words, with doors that only rotate inward, there were problems such as users not being able to move easily in emergencies, obstacles not being able to be removed, and those in need of rescue not being able to be helped. However, because the door can rotate outward, all of these problems can be solved. [Brief explanation of the drawing]

[0036] Embodiments of the present invention will be described below with reference to the drawings. In the following description, identical parts are denoted by the same reference numerals. Their names and functions are also the same. Therefore, detailed descriptions of them will not be repeated.

[0037] (Door opening and closing mechanism 100) Figure 1 is a schematic plan view showing an example of a door opening and closing mechanism 100 according to this embodiment, Figure 2 is a schematic cross-sectional view showing an example of section AA (cross section) of Figure 1, and Figure 3 is a schematic cross-sectional view showing an example of section BB (longitudinal section) of Figure 1.

[0038] As shown in Figure 1, an outer frame 500 is provided for the ceiling CE, floor FL, and wall. The outer frame 500 is arranged in a roughly U-shape on the left and right sides that are in contact with the wall, and on the upper side that is in contact with the ceiling CE. The inner frame 300 is located inside the outer frame 500, on the left and right sides. The door 200 is installed inside the inner frame 300. The upper side of the door 200 faces the outer frame 500, and the left and right sides face the inner frame 300. In this embodiment, the inner frame 300 is mainly made of iron, the door 200 is mainly made of iron or steel and paper core, etc., and the outer frame 500 is mainly made of iron. However, the materials of the door 200, inner frame 300, and outer frame 500 are not limited to those described above, and any material such as aluminum, or other honeycomb structures may be used.

[0039] (Explanation of outer frame 500) Next, the door opening and closing mechanism 100 will be explained using the cross-section shown in Figure 2. As shown in Figure 2, the upper side of the figure is defined as the outside of the door, and the lower side is defined as the inside of the door. This explanation assumes that there is a closed space on either the outside or inside of the door in this embodiment. The closed space also includes the space closed by the movable panel containing the door opening / closing mechanism 100 according to the present invention.

[0040] A left outer frame 510 is provided to the left of the outer frame 500, and a right outer frame 520 is provided to the right of the outer frame 500. Although the outer frame 500 is formed as a single unit, for explanatory purposes, it is named the left outer frame 510, the right outer frame 520, and the upper outer frame 530. The outer frame 500 may also be formed as separate or partially separate parts, for each of the left outer frame 510, the right outer frame 520, and the upper outer frame 530.

[0041] (Explanation of the left outer frame 510) Furthermore, as shown in Figure 2, the left outer frame 510 has a space 511 formed therein that allows the left inner frame 310, which will be described later, to rotate by a hinge member 410 (for example, a component such as a flat hinge).

[0042] (Left inner frame 310) Next, as shown in Figure 2, a left inner frame 310 is provided inside the left outer frame 510, and the hinge member 410 described above is provided between the left outer frame 510 and the left inner frame 310. The left inner frame 310 is provided with a shielding portion 330 having a magnet and a pin 350 for fixing the left inner frame 310 to the left outer frame 510.

[0043] (Right outer frame 520) Furthermore, as shown in Figure 2, the right outer frame 520 has a space 521 formed therein that allows the right inner frame 320, which will be described later, to rotate by a hinge member 420 (for example, a component such as a long hinge). In addition, a hat-shaped contact member 550 is formed on the right outer frame 520 so as to protrude from the inside.

[0044] (Right inner frame 320) Furthermore, as shown in Figure 2, a right inner frame 320 is provided inside the right outer frame 520, and a hinge member 420 is provided between the right outer frame 520 and the right inner frame 320. The right inner frame 320 is provided with a shielding portion 340 having a magnet. Furthermore, a hinge portion 400 (a component of a gravity hinge, etc.) that rotates during normal use of the door is provided on the inside of the right inner frame 320. Furthermore, the right inner frame 320 is provided with a pin 360 that fixes the right inner frame 320 to the contact member 550 of the right outer frame 520. Pin 360 is installed both above and below. Therefore, pins 350 and 360 are provided in a total of four locations. Pins 350 and / or 360 may have a bolt thread structure, or they may have a partially threaded structure. If they have a partially threaded structure, pins 350 or 360 can be removed with fewer turns of the bolt.

[0045] (Door 200) The door 200 in Figure 2 is provided with a contact member 250. Additionally, the right side (one end, the tail end) of the door 200 is fixed to a hinge 400. Furthermore, as shown in Figure 2, the outer side of the door 200 (one side, right side) is shielded by the magnet of the shielding part 340, and the outer side of the door 200 (the other side, left side) is shielded by the magnet of the shielding part 330. The magnet of the shielding part 330 can achieve airtightness because the door 200 is made of steel and / or a paper core, and therefore magnetic attraction acts on it. Furthermore, as shown in Figure 2, a contact member 250 is formed on the door edge side (one side, right side) of the door 200. The contact member 250 is formed to abut against the contact member 550 when the door 200 is in the closed position. Details of the contact member 250 and the contact member 550 will be described later.

[0046] Next, as shown in Figure 3, an upper outer frame 530 is provided on the top of the door 200. Furthermore, a protruding member 260 is provided at part or all of the upper and lower ends of the door 200, which extends and retracts in conjunction with the contact member 250.

[0047] (Door opening and closing mechanism 100 in normal use) Next, Figure 4 is a schematic cross-sectional view showing an example of the operation of the door opening / closing mechanism 100 in normal use, and Figure 5 is a schematic longitudinal cross-sectional view showing an example of the operation of the door opening / closing mechanism 100 in normal use. Figure 5(a) shows an example of the door 200 being open, and Figure 5(b) shows an example of the door 200 being closed.

[0048] From the state shown in Figure 2, as shown in Figure 4, the user of the door opening / closing mechanism 100 rotates the door 200 around the hinge portion 400 in the direction of arrow IN. As a result, the user can easily move inward. In this case, as shown in Figure 5(a), the protruding member 260 is housed inside the door 200. The user then rotates the door 200 in the opposite direction to the arrow IN to close it. In this case, the state changes from the state shown in Figure 4 to the state shown in Figure 2. The contact member 250 provided on the tail end of the door 200 then comes into contact with the abutment member 550, and the contact member 250 moves in a direction that allows it to be housed inside the door 200. That is, the contact member 250 and / or the abutment member 550 are formed to make direct contact through a notch or hole formed in the right inner frame 320.

[0049] In other words, if the contact member 250 is in contact with and pressed against the inner frame 320, causing the protruding member 260 to protrude downward and contact the floor FL, the contact with the floor FL will be maintained even when the inner frame 320 and the door 200 are opened together. To prevent this state from being maintained, a notch or hole can be formed in the inner frame 320 so that the inner frame 320 and the contact member 250 do not come into direct contact. In other words, the contact member 250 and the abutment member 550 attached to the outer frame 500 will come into contact, causing the protruding member 260 to protrude when the door 200 is closed and to retract when it is open, allowing the door 250 to be opened and closed easily.

[0050] As a result, as shown in Figure 5(b), when the door 200 is closed, the protruding members 260 protrude in both the upward and downward directions. Specifically, the protruding member 260 located above the door 200 contacts the lower side of the upper outer frame 530, and the protruding member 260 located below the door 200 contacts the floor FL. This resolves issues such as sound shielding, surreptitious filming, and smoke prevention. The contact member 250 is formed to protrude from the side of the door 200 and is located approximately 30 mm from the upper and lower ends of the door 200. It is also commonly referred to as the door bottom structure. The protruding member 260 may be provided along the entire short side of the door 200.

[0051] Specifically, the amount of movement of the protruding member 260 is preferably about 10 mm. Furthermore, the protruding member 260 is preferably made of an elastic material such as rubber. The user may lock the door 200 with a lock (not shown) after moving using the door opening / closing mechanism 100. In this figure, the lock is omitted.

[0052] (Door opening and closing mechanism 100 for emergency use) Next, Figures 6, 7, and 8 are schematic cross-sectional views showing an example of the operation of the door opening / closing mechanism 100 in the event of emergency use, and Figure 9 is a schematic perspective view showing an example of the operation of the door opening / closing mechanism 100 in the event of emergency use.

[0053] As shown in Figures 6 to 9, in case of emergency use, the pin 350 of the door opening / closing mechanism 100 is removed. In this case, the left inner frame 310, which was fixed by the pin 350, can be rotated in the direction of arrow E1 while being pivotally supported by the hinge member 410.

[0054] Next, as shown in Figure 7, the pin 360 of the door opening / closing mechanism 100 is removed. In this case, the right inner frame 320, which was fixed by the pin 360, can be separated from the contact member 550 of the right outer frame 520. In this case, as shown in Figures 8 and 9, the door 200 can be opened in the direction of arrow OP while the right inner frame 320 is pivotally supported by the hinge member 420. Even in this case, the contact member 250 provided on the tail end side (one side, right side) of the door 200 is separated from the contact member 550, so the protruding member 260 is housed inside the door 200, and the door 200 can be easily opened and closed.

[0065] (Door opening and closing mechanism 100 for emergency use) Next, Figures 20 and 21 are schematic cross-sectional views showing an example of the operation of the door opening and closing mechanism 100 in the event of emergency use.

[0066] As shown in Figures 20 and 21, by removing the pin 350, the upper inner frame, the left inner frame 310, and the right inner frame 320 open outwards together with the door 200. In this case, users can move easily in an emergency, remove obstacles, and help those in need of rescue.

[0067] (Fourth embodiment) Next, Figure 22 is a schematic plan view showing an example of the door opening and closing mechanism 100 according to the fourth embodiment, and Figure 23 is a schematic cross-sectional view showing an example of section AA (cross-section) of Figure 22. The differences between the fourth embodiment and the embodiments described above will be explained below.

[0068] As shown in Figures 22 and 23, the door opening and closing mechanism 100 according to the fourth embodiment has a structure that includes a locking mechanism 370 and a shutter 380. The locking mechanism 370 is not limited to the door edge lock (door edge latch lock) structure, and any structure such as a cylinder lock, a cremone lock with a lever handle, a thumbturn with a knob, a meeting stile lock, a surface-mounted deadbolt lock, a deadbolt lock, an electronic lock, or an electric lock may be used.

[0069] As shown in Figures 22 and 23, shutters 380 are provided on the top and bottom of the door edge. A locking mechanism 370 is built into the inside of the door 200 on which the shutters 380 are provided. The shutters 380 are not necessarily required; they may be replaced with a privacy seal or the like, and the keyhole of the locking mechanism 370 may be exposed on the surface of the door 200.

[0070] (Door opening and closing mechanism 100 in normal use) Next, Figure 24 is a schematic cross-sectional view showing an example of the operation of the door opening and closing mechanism 100 during normal use.

[0071] As shown in Figure 24, the user can move by rotating the door 200 in the direction of arrow OP, around the hinge portion 400 (a component such as a gravity hinge) that rotates during normal use of the door. Furthermore, in this case, the upper inner frame, the left inner frame 310, and the right inner frame 320 do not move in conjunction with the movement of the door 200 in the direction of the arrow OP.

[0072] (Door opening and closing mechanism 100 for emergency use) Next, Figures 25 and 26 are schematic diagrams illustrating an example of the operation of the door opening / closing mechanism 100 in the event of emergency use, and Figure 27 is a schematic cross-sectional view illustrating an example of the operation of the door opening / closing mechanism 100 in the event of emergency use.

[0073] First, as shown in Figures 25(a) and (b), in the event of emergency use, the user moves the knob 381 of the shutter 380 in the direction of arrow SL1 and inserts the key KEY into the locking mechanism 370, as shown in Figure 25(c). Then, as shown in Figure 25(d), rotate it in the direction of arrow R1.

[0074] In this case, as shown in Figures 26(a) and (b), the L-shaped member 371 of the locking mechanism 370 is withdrawn from the hole 515 provided in the left outer frame 510 and separated as the key rotates. Next, as shown in Figure 26(c), the L-shaped member 371 stands upright, and by removing the key from the locking mechanism 370, as shown in Figure 26(d), the left inner frame 310 (door edge side) rotates together with the locking structure 370 around the hinge member 410.

[0075] In other words, as shown in Figure 27, the left inner frame 310 (door edge side) rotates, causing the door 200 to rotate in the direction of arrow OP around the hinge member 420 of the door 200, thereby allowing the user to move. Furthermore, in this case, the upper inner frame, the left inner frame 310, and the right inner frame 320 do not move in conjunction with the movement of the door 200 in the direction of the arrow OP.

[0076] As described above, in the door opening and closing mechanism 100 according to the present invention, since the door 200 is an inward-opening door during normal use, space saving can be achieved. Although outward opening is achieved using pins 350, 360 and a locking structure 370, when applied to an emergency door, the structure of the door opening and closing mechanism 100 according to the present invention may be provided on both the inward-opening and outward-opening sides in case the inner lock is locked and the key is unavailable. Furthermore, it can also be applied to partition panels or movable panels. Similarly, for partition panels or movable panels, the structure of the door opening and closing mechanism 100 according to the present invention may be provided for normal inward opening and emergency outward opening, or normal inward opening, emergency inward opening and outward opening.

[0077] Furthermore, it allows users to move easily in emergencies, remove obstacles, and assist those in need of rescue. Furthermore, in this embodiment, since there is no door stopper on the floor, cleaning can be easily performed. In addition, in this embodiment, when the door 200 is closed, the protruding member 260 can achieve a sealed environment. As a result, it becomes easy to maintain high levels of sound insulation, security, and smoke protection.
