Description

[Technical field]

[0001] The present invention relates to a toilet opening and closing mechanism and a private toilet. [Background technology]

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

[0003] The shielding structure for an emergency outward-swinging door described in Patent Document 1 is a door attached to a door frame so that it can open inward under normal circumstances and open outward in an emergency, and is used to shield the gap between the door edge and the end frame of the door frame.The shielding structure for an emergency outward-swinging door is equipped with a movable part that has a recess and is supported so that it can rotate in a horizontal plane, and a fixed part that has a convex part that fits into the recess, and with the movable part attached to either the door edge or the end frame and the fixed part attached to the other, when the outer end of the movable part is moved in a direction that widens the gap due to the action of an external force with the door closed, the inner end of the movable part moves in a direction that closes the gap.

[0004] Patent Document 2 (JP 2013-124485 A) discloses an opening and closing structure for a toilet booth or shower booth door that is designed to be extremely safe overall, preventing serious injury even if a finger is caught between a partition panel and the door edge when opening or closing the door, such as in the hinge part between the partition panel on the hanging side and the door edge, or in the gap between the partition panel on the door tip side and the door edge.

[0005] The opening and closing structure for a toilet booth or shower booth door described in Patent Document 2 is a toilet booth or shower booth door opening and closing structure having a sleeve wall edge member and a door edge member attached to each of the door hanging part and the door end part, and is characterized in that at each of the door hanging part and the door end part, either one or both of the opposing sleeve wall edge member and door edge member are formed from an elastic material continuously from the top to the bottom of the sleeve wall or door, and a hollow portion is formed inside it extending from the top to the bottom, resulting in a structure that can be elastically deformed by an external force.

[0006] Patent Document 3 (JP 2022-14144 A) discloses a doorstop device that can smoothly and quickly open an inward-opening door outward in an emergency.

[0007] The doorstop device described in Patent Document 3 allows a door, which is rotatably attached to one vertical frame part of a door frame that defines the entrance of the booth, to rotate from a closed position that closes the entrance into the booth and prohibits the door from rotating out of the booth. The doorstop device comprises a base fixed to the upper frame part or the other vertical frame part of the door frame, a doorstop member connected to the base so as to be rotatable between a restricted position where it interferes with the door's rotation trajectory and a retracted position where it does not interfere with the door's rotation trajectory, and a locking mechanism that locks the doorstop member to the base in the restricted position and has a release operation part that releases this locked state.

[0008] Patent Document 4 (JP Patent Publication 2004-346565 A) discloses that in a door stop device having a movable door stop member, the door stop release operation is made easy and quick.

[0009] The doorstop device described in Patent Document 4 is a doorstop device that is attached to an inward-opening door and has a movable doorstop member that can be moved to an outward-opening restricting position that restricts the door from opening outward, and an outward-opening allowable position that allows the door to open outward. Under normal circumstances, the movable doorstop member is held in the outward-opening restricting position, and in an emergency, the movable doorstop member is moved to the outward-opening allowable position in response to the operation of a push button that faces the outside of the room through a through hole in the door.

[0010] Patent Document 5 (JP 2014-141871 A) discloses an emergency unlocking mechanism, a swing door device, and a private room unit that allow an inward-swinging door to easily open outward in an emergency and is less likely to be damaged.

[0011] The emergency unlocking mechanism described in Patent Document 5 comprises a door edge fixed to the tip of a swinging door attached to a panel that constitutes an entrance to a room, a flexible pin held on the door edge so as to rotate relative to the door edge around an axis parallel to the rotation center of the swinging door relative to the panel, and a lock attached to the tip of the swinging door, wherein the flexible pin has a rotation axis and a wing that is attached to the rotation axis and extends radially outward from the rotation axis, covering the gap between the tip of the swinging door and the panel, and the lock has a lock body attached to the swinging door and a receiving member that is attached to the panel and engages with the lock body, and the lock body has a normal state in which it can engage with the receiving member and an emergency unlocking state in which it is released from its engagement with the receiving member, and in the normal state, the flexible pin is held so that at least a part of the wing abuts against the outer surface of the panel that faces the inside of the room, thereby restricting the operation of the swinging door to only opening inward, and in the emergency unlocking state, the flexible pin is allowed to move to a position where the wing and the panel do not come into contact, allowing the swinging door to open both ways.

[0012] [Patent Document 1] Patent No. 6674505 [Patent Document 2] JP 2013-124485 A [Patent Document 3] Patent Publication No. 2022-14144 [Patent Document 4] JP 2004-346565 A [Patent Document 5] JP 2014-141871 A Summary of the Invention [Problem to be solved by the invention]

[0013] In general, in restrooms, doors that open inward are used so that the space on the aisle side is not obstructed. These doors that open inward can save space in the restroom for both men and women. In addition, doors with doorstops are often used to prevent noise from excretion and / or crimes such as voyeurism. In recent years, awareness of all-gender toilets has begun to increase, and the demand for their installation is on the rise. In particular, there is a demand for the development of all-gender toilets that can be used regardless of gender. However, swing doors with doorstops are used for soundproofing and / or to prevent voyeurism, and there is a problem with swing doors with doorstops because they are designed to make it difficult to escape or rescue people in an emergency.

[0014] Toilet doors are generally designed to open outward in the event of an emergency, assuming that a toilet user will lean against it and fall over. However, if there is a doorstop in the path of traffic that causes the door to open outward, it cannot be opened outward in an emergency, which creates a problem.

[0015] The shielding structure for emergency outward-opening doors described in Patent Document 1 has the advantage of preventing others from widening the gap from the outside and peeking inside, but it is difficult to improve the soundproofing properties required for the development of all-gender toilets that can be used regardless of gender. Furthermore, the opening and closing structure for the toilet booth or shower booth door described in Patent Document 2, the doorstop device described in Patent Document 3, the doorstop device described in Patent Document 4, and the emergency unlocking mechanism described in Patent Document 5 make it difficult to improve the soundproofing required for the development of all-gender toilets that can be used regardless of gender, and do not provide toilet users with the peace of mind that the door will only be opened to the outside in an emergency.

[0016] An object of the present invention is to provide a toilet opening and closing mechanism and a private toilet that opens inward when in use and can open outward in an emergency. Another object of the present invention is to provide a toilet opening and closing mechanism and a private toilet that maintains high sound insulation, opens inward when in use, and can open outward in an emergency. [Means for solving the problem]

[0017] (1) A toilet opening and closing mechanism according to one aspect includes a door for entering and exiting the toilet, a door hinge provided inside the toilet that supports the opening and closing of the door and allows the door to rotate inside the toilet, an inner frame with a door stop formed on at least one side of the door, an outer frame provided on the upper and side of the door except for the lower side, a one-side hinge provided on one side where the door hinge is provided to connect the inner and outer frames, a other-side hinge provided on the other side of the side to connect the inner and outer frames, and a other-side release portion for releasing the rotation of the other-side hinge, wherein the other-side release portion rotates the other-side hinge to rotate a part of the inner frame outside the toilet, allowing the door to rotate outside the toilet by the one-side hinge.

[0018] In this case, the other side release part rotates the hinge on the other side to rotate a part of the inner frame to the outside of the toilet, and the door can be rotated to the outside of the toilet by the hinge on one side. That is, during normal use, the door can be rotated to the inside of the toilet, and in the case of an emergency or emergency, the other side release part can rotate the door to the outside of the toilet. As a result, people in need of rescue in the toilet can be easily rescued. In other words, with a door that pivots inward, there is a problem that the person in need of rescue can get caught between the toilet bowl and the door, and the door cannot open completely, making it difficult to rescue the person in need of rescue. However, because the door can be pivoted outward, the person in need of rescue can be easily rescued.

[0019] (2) The toilet opening and closing mechanism of the second invention is a toilet opening and closing mechanism of one aspect of the invention, wherein the inner frame consists of one frame on one side and another frame on the other side, and may further include a one-side release portion for releasing the rotation of the hinge on one side.

[0020] In this case, since the inner frame is composed of a first frame and a second frame, the door can be opened outward in a large space by releasing the first frame and the second frame. As a result, the person in need of rescue can be rescued smoothly. In addition, since the inner frame is composed of a first frame and a second frame, the strength of the inner frame can be increased. In addition, the first side release portion and the second side release portion can be provided at two or four locations among the top, bottom, left and right with bolts or bolts having a partially screwed shape, so that the inner frame can be easily released.

[0021] (3) The toilet opening / closing mechanism according to the third invention is a toilet opening / closing mechanism according to one aspect of the invention, wherein the inner frame may consist of two frames with one side and an upper side integrated together, and another frame on the other side.

[0022] In this case, the door can be opened outward by rotating the other frame. As a result, the rescuer can be rescued smoothly. In this case, by opening the two frames, one side and the upper side of which are integrated, together with the door, there is no need to provide a one-side release section, and the number of parts can be reduced.

[0023] (4) The toilet opening / closing mechanism according to a fourth aspect of the present invention is a toilet opening / closing mechanism according to one aspect of the present invention, wherein the inner frame may be made up of three frames in which one side, the other side and the upper side are integrated.

[0024] In this case, the three-sided frame can be opened outward together with the door. As a result, the rescuer can be rescued smoothly. In this case, by opening the three-sided frame together with the door, there is no need to provide a one-side release section, which reduces the number of parts.

[0025] (5) The frame structure of the fifth invention is a toilet opening and closing mechanism of any of the first to fourth inventions, and includes a protruding member built into the door, an abutment member provided on the outer frame, and a contact member that contacts the abutment member, and the protruding member provided inside the door may be protruded when the contact member is pressed by the abutment member.

[0026] In this case, the contact member is pressed by the abutting member to cause the protruding member provided inside the door to protrude, so that the gap between the door and the floor and the gap between the door and the ceiling can be closed.

[0027] (6) The toilet opening and closing mechanism of the sixth invention is the toilet opening and closing mechanism of the fifth invention, wherein the protruding member may be provided on at least one, or more than one, or all of the above, both sides, and below the door.

[0028] In this case, the protruding members are provided on at least one, or multiple, or all of the top, both sides, and bottom of the door, thereby improving sound insulation. In addition, the protruding members may be provided only in the vertical direction of the door, and shielding portions may be provided on the left and right sides of the door.

[0029] (7) A toilet opening and closing mechanism of another invention includes a door for entering and exiting the toilet, a protruding member built into the door, a door hinge provided on the inside of the toilet and supporting the opening and closing of the door and allowing the door to rotate inside the toilet, an inner frame with a door stop formed on at least one side of the door, and an outer frame provided on the upper side and / or side of the door other than the lower side, and the protruding member provided inside the door is protruded when a contact member linked to the protruding member comes into contact with and presses against the outer frame or an abutment member attached to the outer frame.

[0030] In this case, the protruding members are provided on at least one, or multiple, or all of the top, both sides, and bottom of the door, thereby improving sound insulation. In addition, the protruding members may be provided only in the vertical direction of the door, and shielding portions may be provided on the left and right sides of the door. As a result, when the door is closed, the protruding member protrudes, improving sound insulation, and when the door is opened or in an emergency, the protruding member is retracted, allowing the door to move smoothly in the opening direction.

[0031] (8) A private toilet according to still another aspect is provided with the toilet opening / closing mechanism according to the one aspect.

[0032] In this case, the other side release part rotates the hinge on the other side to rotate a part of the inner frame to the outside of the toilet, and the door can be rotated to the outside of the toilet by the hinge on one side. That is, during normal use, the door can be rotated to the inside of the toilet, and in the case of an emergency or emergency, the other side release part can rotate the door to the outside of the toilet. As a result, people in need of rescue in the toilet can be easily rescued. In other words, with a door that pivots inward, there is a problem that the person in need of rescue can get caught between the toilet bowl and the door, and the door cannot open completely, making it difficult to rescue the person in need of rescue. However, because the door can be pivoted outward, the person in need of rescue can be easily rescued. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0034] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the following description, the same components are denoted by the same reference numerals. Their names and functions are also the same. Therefore, detailed description thereof will not be repeated.

[0035] (Toilet opening and closing mechanism 100) FIG. 1 is a schematic plan view showing an example of a toilet opening / closing mechanism 100 in this embodiment, FIG. 2 is a schematic cross-sectional view showing an example of an AA section (horizontal section) of FIG. 1, and FIG. 3 is a schematic cross-sectional view showing an example of a BB section (longitudinal section) of FIG. 1.

[0036] As shown in FIG. 1, an outer frame 500 is provided for a ceiling CE, a floor FL and walls. The outer frame 500 is arranged in a generally U-shape on the left and right side portions that contact the walls and on the upper portion that contacts the ceiling CE. The inner frames 300 are arranged on the left and right side portions inside the outer frame 500. The door 200 is provided inside the inner frame 300. The upper side of the door 200 faces the outer frame 500, and the left and right side portions 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, and the outer frame 500 is mainly made of iron. The materials of the door 200, the inner frame 300, and the outer frame 500 are not limited to those mentioned above, and any material such as aluminum may be used.

[0037] (Explanation of outer frame 500) Next, the toilet opening / closing mechanism 100 will be described with reference to the cross section shown in FIG. As shown in FIG. 2, the upper side of the figure is defined as the outside of the toilet, and the lower side of the figure is defined as the inside of the toilet. A left outer frame 510 is provided on the left side of the outer frame 500, and a right outer frame 520 is provided on the right side of the outer frame 500. Although the outer frame 500 is formed as a single unit, for the sake of explanation, the names of the left outer frame 510, the right outer frame 520, and the upper outer frame 530 are given to the outer frame 500. Note that the left outer frame 510, the right outer frame 520, and the upper outer frame 530 of the outer frame 500 may be formed as separate bodies or partially separate bodies.

[0038] (Explanation of the left outer frame 510) As shown in FIG. 2, the left outer frame 510 has a space 511 formed therein in which the left inner frame 310, which will be described later, can rotate by a hinge member 410 (for example, a component member such as a flat hinge).

[0039] (Left inner frame 310) Next, as shown in FIG. 2, the left side inner frame 310 is provided inside the left side outer frame 510, and the above-mentioned hinge member 410 is provided between the left side outer frame 510 and the left side 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 .

[0040] (Right outer frame 520) 2, a space 521 is formed in the right outer frame 520, in which the right inner frame 320 described later can rotate by a hinge member 420 (for example, a component member such as a long hinge). Also, a hat-shaped abutment member 550 is formed in the right outer frame 520 so as to protrude from the inside.

[0041] (Right side inner frame 320) As shown in FIG. 2, the 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. A shielding section 340 having a magnet is provided on the right inner frame 320. Also, on the inside of the right inner frame 320, a hinge section 400 (a component such as a gravity hinge) that rotates during normal use of the toilet is provided. Further, the right inner frame 320 is provided with a pin 360 for fixing the right inner frame 320 to the abutment member 550 of the right outer frame 520 . The pins 360 are provided at four locations in total, one above the other. The pins 360 may have a bolt and screw structure, or may have a structure with only a partial screw structure. If only a partial screw structure is used, the pins 360 can be removed with a small number of turns of the bolt.

[0042] (Door 200) 2 is provided with a contact member 250. Also, a hinge portion 400 is fixed to the right side (one end side, door trailing edge side) of the door 200. 2, the outside of the trailing edge of door 200 (one side, right side) is shielded by a magnet in shielding section 340, and the outside of the leading edge of door 200 (the other side, left side) is shielded by a magnet in shielding section 330. Since door 200 is made of steel or the like, the magnet in shielding section 330 is able to achieve airtightness by the action of magnetic attraction. 2, a contact member 250 is formed on the door end side (one side, the right side) of the door 200. The contact member 250 is formed to come into contact with an abutment member 550 when the door 200 is in a closed state. The contact member 250 and the abutment member 550 will be described in detail later.

[0043] Next, as shown in FIG. 3, an upper outer frame 530 is provided at the upper portion of the door 200. Further, a protruding member 260 that expands and contracts in conjunction with the contact member 250 is provided on a part or all of the upper and lower ends of the door 200 .

[0044] (Toilet opening and closing mechanism 100 in normal use) Next, Fig. 4 is a schematic cross-sectional view showing an example of the operation of the toilet opening / closing mechanism 100 in normal use, and Fig. 5 is a schematic vertical cross-sectional view showing an example of the operation of the toilet opening / closing mechanism 100 in normal use. Fig. 5(a) shows an example of the operation of the door 200 when it is open, and Fig. 5(b) shows an example of the operation of the door 200 when it is closed.

[0045] From the state shown in Fig. 2 to the state shown in Fig. 4, a user of the toilet rotates door 200 in the direction of arrow IN about hinge portion 400. As a result, the user can easily enter the toilet. In this case, as shown in FIG. 5(a), the protruding member 260 is housed in the door 200. Then, the user rotates the toilet door 200 in the direction opposite to the direction of the arrow IN to close it. In this case, the state shown in FIG. 4 transitions to the state shown in FIG. 2. Then, the contact member 250 provided on the trailing edge of the door 200 comes into contact with the abutting member 550, and the contact member 250 moves in a direction to be housed in the door 200. That is, the contact member 250 and / or the abutting member 550 are formed so as to come into direct contact with a notch or hole formed in the right inner frame 320. That is, in the case where the contact member 250 is in contact with the inner frame 320 and pressed, and the protruding member 260 protrudes downward and contacts the floor FL, the contact state with the floor FL is maintained even when the inner frame 320 and the door 200 are released together. In order 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 with each other. That is, the contact member 250 comes into contact with the abutment member 550 attached to the outer frame 500, and when the door 200 is closed, the protruding member 260 protrudes, and when the door 200 is released, the protruding member 260 is stored in its protruding state, so that the door 250 can be opened and closed easily.

[0046] 5(b), the protruding members 260 protrude in both the up and down directions. Specifically, the protruding members 260 provided above the door 200 contact the underside of the upper outer frame 530, and the protruding members 260 provided below the door 200 contact the floor FL. This can eliminate problems such as sound shielding for the user and voyeurism. The contact members 250 are formed to protrude from the side surfaces of the door 200, and are provided approximately 30 mm from the upper and lower ends of the door 200. This is generally also called a door bottom structure. The protruding member 260 is provided over the entire short side of the door 200.

[0047] Specifically, the amount of movement of the protruding member 260 is preferably about 10 mm. Moreover, the protruding member 260 is preferably made of an elastic material such as rubber. After entering the toilet, the user locks the door. The key is omitted in this drawing.

[0048] (Toilet 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 toilet opening and closing mechanism 100 in the case of emergency use, and Figure 9 is a schematic oblique view showing an example of the operation of the toilet opening and closing mechanism 100 in the case of emergency use.

[0049] 6 and 9, in the case of emergency use, the pin 350 of the toilet opening / closing mechanism 100 is removed. In this case, the left inner frame 310 fixed by the pin 350 can be pivoted in the direction of the arrow E1 while being pivotally supported by the hinge member 410.

[0050] Next, as shown in Fig. 7, the pin 360 of the toilet opening / closing mechanism 100 is removed. In this case, the right-side inner frame 320 fixed by the pin 360 can be separated from the abutment member 550 of the right-side outer frame 520. In this case, as shown in Fig. 8 and Fig. 9, the door 200 can be opened in the direction of the arrow OP while the right-side inner frame 320 is pivotally supported by the hinge member 420. Even in this case, the contact member 250 provided on the trailing edge (one side, right side) of the door 200 moves away from the abutment member 550, and the protruding member 260 is accommodated within the door 200, so that the door 200 can be easily opened and closed.

[0051] (Second embodiment) Next, Fig. 10 is a schematic plan view showing an example of a toilet opening / closing mechanism 100 according to a second embodiment, Fig. 11 is a schematic cross-sectional view showing an example of an AA cross section (horizontal cross section) in Fig. 10, and Fig. 12 is a schematic cross-sectional view showing an example of a BB cross section (longitudinal cross section) in Fig. 10. Below, the differences between the second embodiment and the above-mentioned embodiment will be described.

[0052] As shown in Figures 10, 11, and 12, in the toilet opening / closing mechanism 100 according to the second embodiment, the structure of the inner frame 300 is provided with a left inner frame 310 and upper and right inner frames 320 instead of the left inner frame 310 and the right inner frame 320. The upper inner frame and the right inner frame 320 are formed as an integral member. In this embodiment, the upper inner frame and the right inner frame 320 may be formed separately and then fastened together with bolts or the like to form an integrated member.

[0053] (Toilet opening and closing mechanism 100 in normal use) Next, FIG. 13 is a schematic cross-sectional view showing an example of the operation of the toilet opening / closing mechanism 100 in normal use.

[0054] As shown in Figs. 11 and 13, a user can enter the toilet by rotating the door 200 in the direction of the arrow OP. In this case, the upper inner frame 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.

[0058] As shown in Figures 16, 17, and 18, in the toilet opening and closing mechanism 100 of the third embodiment, the structure of the inner frame 300 is such that the upper inner frame, the left inner frame 310, and the right inner frame 320 are formed as a single integral member. In this embodiment, the upper inner frame, the left inner frame 310 and the right inner frame 320 may be formed separately and then fastened together with bolts or the like to form an integrated member.

[0059] (Toilet opening and closing mechanism 100 in normal use) Next, FIG. 19 is a schematic cross-sectional view showing an example of the operation of the toilet opening / closing mechanism 100 in normal use.

[0060] As shown in Figs. 17 and 19, a user can enter the toilet by rotating the door 200 in the direction of the arrow OP. In this case, the upper inner frame, the left inner frame 310 and the right inner frame 320 are not linked to the movement of the door 200 in the direction of the arrow OP.

[0061] (Toilet opening and closing mechanism 100 for emergency use) Next, FIG. 20 and FIG. 21 are schematic cross-sectional views showing an example of the operation of the toilet opening / closing mechanism 100 in the case of emergency use.

[0062] As shown in Figures 20 and 21, by removing the pins 350, the top, left and right inner frames 310, 320, together with the door 200, are swung outward. In this case, the user in the toilet can be appropriately rescued. Also, by opening the door 200 to the outside, it becomes unnecessary to consider the effect on the person in need of rescue and the toilet seat.

[0063] As described above, in the toilet opening and closing mechanism 100 according to the present invention, the door 200 swings inward during normal use, so space can be saved. In addition, in an emergency, it is assumed that a user inside the toilet will lean against the door 200 and fall, but in this embodiment, the door 200 can be opened outward to facilitate rescue, etc. In addition, in this embodiment, since there is no door stop on the floor, cleaning can be easily performed. Furthermore, in this embodiment, when the door 200 is closed, the protruding member 260 can achieve a tight seal. As a result, it is possible to easily maintain high sound insulation and crime prevention.

[0064] In the present invention, toilet opening / closing mechanism 100 corresponds to the "toilet opening / closing mechanism", door 200 corresponds to the "door", hinge portion 400 corresponds to the "door hinge", inner frame 300 corresponds to the "inner frame", outer frame 500 corresponds to the "outer frame", hinge member 420 corresponds to the "hinge on one side", hinge member 410 corresponds to the "hinge on the other side", pin 350 corresponds to the "other side release portion", right side inner frame 320 corresponds to the "one side frame", left side inner frame 310 corresponds to the "other side frame", pin 360 corresponds to the "one side release portion", protruding member 260 corresponds to the "protruding member", abutting member 550 corresponds to the "abutting member", and contact member 250 corresponds to the "contact member".

[0065] Although a preferred embodiment of the present invention is as described above, the present invention is not limited thereto. It is understood that various other embodiments can be made without departing from the spirit and scope of the present invention. Furthermore, although the actions and effects of the configuration of the present invention are described in this embodiment, these actions and effects are merely examples and do not limit the present invention.
