Description

[Technical Field]

[0001] The present invention relates to an inward-opening door device that is attached to the entrance of a room such as a toilet booth, and a method for opening and closing the door device to the outside of the room. [Background technology]

[0002] Generally, when a door body (door frame, door panel) is installed at the entrance of a room (small room) such as a toilet booth or bathroom booth, the door body is an inward-opening type that opens toward the interior of the room, and consideration is given to preventing the door body from hitting people outside the room when it is opened. In such an inward-opening door device, edge members are attached to the leading edge of the door body and to the leading edge of the panel body opposite the leading edge, respectively, and these two edge members are configured such that, for example, the door body edge member has a bulging surface (arcuate surface) at the leading end side portion that bulges toward the center in the front-to-rear direction, while the panel body edge member has an extension formed in the outside portion to close the gap between the two edge members and conceal the view into the room. In such door systems, if a person inside the room falls near the entrance due to health issues or other reasons, the fallen person may become an obstacle, preventing the door body from opening to the inside of the room and hindering emergency response. To deal with such situations, it has been proposed to exceptionally configure an inward-opening door body so that it opens to the outside. However, in this case, the bulging side edge of the door body edge member abuts against the extension provided for privacy purposes, preventing the door body from opening to the outside. Therefore, there is known a door that is configured so that an inward-opening door body can be opened to the outside in the event of an emergency such as that described above (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 6798829 Summary of the Invention [Problem to be solved by the invention]

[0004] In the case of the conventional inward-opening door body that is designed to be able to be opened to the outside in an emergency, the extension provided on the edge member on the panel body side is made of a flexible material, and when the door body is moved to open to the outside, if the tip side portion of the edge member on the door body side abuts, the extension deforms in an arc toward the outside, allowing the door body to be opened to the outside. However, in this case, since the extension is made of a flexible, deformable material, part of the extension can be pried open to the outside of the room during normal use. This priing open allows someone to look inside the room from outside, which reduces security, and the present invention aims to solve these problems. [Means for solving the problem]

[0005] The present invention was created in consideration of the above-mentioned circumstances and with the aim of solving these problems. The invention of claim 1 is an inward-opening door device comprising left and right front and rear panel bodies that separate the interior and exterior of a room, and an inward-opening door body that opens and closes the entrance formed between the front and rear panel bodies by opening it toward the interior of the room, and door body and panel body edge members are provided on the opposing edges of the door body and front panel body, respectively. The leading side of one of the edge members has a bulging surface that bulges toward the center in the front-to-rear direction, while the outside edge of the other edge member has an extension portion that extends toward the one edge member and closes the gap between the two edge members. In this inward-opening door device, the other edge member is divided into an edge main body portion and an extension portion, and the divided extension portion is arranged to swing freely toward the outside of the room in conjunction with the abutment of the one edge member when the door body is operated to open toward the outside of the room, allowing the door body to be opened to the outside.

The invention of claim 4 is an inward-opening door device comprising left and right door-leading and door-rear-end panel bodies that separate the interior and exterior of a room, and an inward-opening door body that opens and closes an entrance formed between the door-leading and door-rear-end panel bodies by opening it toward the interior of the room, wherein a door-body edge member that bulges out at the center of the front and rear direction of the leading edge side portion is provided at the leading edge of the door body, and a panel-body edge member that has an extension portion formed at the leading edge of the panel body that extends toward the door body and closes the gap between the door-body edge member and the door-body edge member, and wherein the panel-body edge member is divided into an edge body and an extension portion, The divided extension portions are provided so as to be able to swing freely so as to assume an allowable position that allows the door body to be opened to the outside, and the method for opening and closing the door body to the outside of the room is characterized in that, when the door body is operated to open to the outside of the room, the following steps are executed: a door body opening step in which, when the door body is opened to the outside, the door body edge member abuts against the extension portion, and the extension portion swings and transforms into an allowable position that allows movement of the door body to the opening side; a door body closing step in which the door body opened to the outside of the room is closed; and an extension portion return step in which, after the door body closing step, the extension portion swings back from the allowable position to its original position. The invention of claim 5 is an inward-opening door device comprising left and right door-leading and door-rear-end panel bodies that separate the interior and exterior of a room, and an inward-opening door body that opens and closes an entrance formed between the door-leading and door-rear-end panel bodies by opening it toward the interior of the room, wherein a door-body-side edge member that bulges out at the center of the front and rear direction of the leading edge side portion is provided at the leading edge of the door body, and a panel-body-side edge member that has an extension portion formed at the leading edge of the panel body and that extends toward the door body to close a gap between the door-body-side edge member and the door-body-side edge member at its outer edge, wherein the panel-body-side edge member is divided into an edge body and an extension portion, and the divided extension portion is The door body is provided so as to be able to swing freely into an allowable position that allows the door body to be opened to the outside of the room, and the method for opening and closing the door body to the outside of the room includes the following steps: a door body opening step in which, when the door body is operated to open toward the outside, the edge member on the door body abuts against the extension portion, and the extension portion swings and changes its shape to an allowable position that allows the door body to move toward the opening side; and a door body closing step in which, when the door body opened to the outside of the room is operated to close, the edge member on the door body abuts against the extension portion, and the extension portion swings and changes its shape to its original position that closes the gap. [Effects of the Invention]

[0006] By adopting the configurations of claims 1 and 4, of the edge members provided on the leading edge of the door body and the opposing leading panel edge, the tip side portion of one edge member is made into a bulging surface that bulges out toward the center in the front-to-rear direction, and an extension portion is provided on the outside edge portion of the other edge member to extend toward the one edge member and close the gap between the two edge members, and the other edge member is divided into an edge main body portion and an extension portion, and the divided extension portion is configured to swing freely to allow the door body to be opened to the outside by swinging to the outside in conjunction with the abutment of the one edge member when the door body is opened to the outside.As a result, the extension portion does not need to be made of a deformable flexible material to allow the door body to be opened to the outside, and can be made of a hard material similar to the edge member.This means that the extension portion cannot be pryed open from the outside to see inside the room, improving security. According to the invention of claim 2, the door body side edge member is the one side edge member and the panel body side edge member is the other side edge member, and the extension portion comprises a swing shaft portion provided on the outdoor side edge portion of the panel body side edge member, an outdoor side side portion extending from the swing shaft while following the outdoor side face of the panel body, a front side side portion having the tip edge of the outdoor side side portion as its apex and extending from the tip edge to the indoor side while following the tip side face portion of the one side edge member, and a folded piece portion bent from the tip edge of the front side side portion towards the panel body, and the folded piece portion is force-fitted into the outdoor side edge of the edge main body portion so that it can be inserted and removed freely. As a result, the swing of the extension portion toward the outdoor side is linked to the abutment of the door body side edge member and it easily changes into the permissible position, but it is not easy to change from the outdoor side to the permissible position, which further improves security. By adopting the inventions of claims 3 and 5, a locking portion is formed on the tip side portion of the edge member on one side, which locks onto the extension portion that has swung toward the outside of the room when closing the door body that is open toward the outside of the room, and moves the extension portion back to its original position.This means that the extension portion that has been deformed toward the outside of the room can be returned to its original position in conjunction with the closing operation of the door body, improving operability.

[0008] The following describes an embodiment of the present invention with reference to the drawings. In the drawings, reference numeral 1 denotes a toilet booth provided in a room. The toilet booth 1 is partitioned by left and right front door-edge and rear door-edge panel bodies 2 and 3, front and rear depth panel bodies 15, and a main body wall surface W. To open and close an entrance E formed between the door-edge and rear door-edge panel bodies 2 and 3, the rear door body is provided with an inward-opening door body 4 pivotally supported on a swing support shaft 4c at the rear door side so as to be able to swing back and forth in the longitudinal direction, all of which are conventional. The present invention is implemented by attaching a door body edge member 5 to the leading edge of the door body 4, and attaching a panel body edge member 6 to the leading edge of the door body panel 2 that faces the door body 4. The specific configuration of these edge members 5 and 6 will be explained below, but since both edge members 5 and 6 only need to have a structure relative to each other, the present invention can also be implemented with a configuration opposite to this embodiment in which a member with the same structure as the door body edge member 5 is attached to the door body panel 2, and a member with the same structure as the panel body edge member 6 is attached to the door body 4.

[0009] The door body edge member 5 is configured to include front and rear locking pieces 5a whose base ends are L-shaped and lock onto the front and rear corners of the leading edge end face 4a of the door body 4, tip side surfaces 5b that extend inward in the front-to-rear direction from the front and rear locking pieces 5a in an arc-shaped shape that bulges towards the leading edge panel body 2, and front and rear support pieces 5c that extend from the front-to-rear intermediate parts of the tip side surfaces 5b to abut against the leading edge end face 4a of the door body, and is configured to be attached to the leading edge end face 4a of the door body 4 by inserting screws 5d between the front and rear support pieces 5c and screwing them into the leading edge vertical frame 4b of the door body 4.

[0010] On the other hand, the panel body side edge member 6 is divided into an edge main body portion 7 on the indoor side and an extension portion 8 on the outdoor side. The edge body portion 7 comprises an interior (rear) locking piece portion 7a that is L-shaped and locks onto the interior corner portion of the tip side surface portion 2a of the door-end side panel body 2, a tip side surface portion 7b that extends from the tip edge portion of the interior locking piece portion 7a toward the exterior to a front position reaching the exterior side surface 2b of the door-end side panel body 2 while leaving a gap S with the tip side surface portion 5b of the door body side edge member 5, an exterior support piece portion 7c that bends from the exterior edge of the tip side surface portion 7b toward the door-end side panel body 2 and reaches the tip side surface 2a of the door-end side panel body 2, and a base end of the exterior support piece portion 7c that fits against (abuts against) the tip side surface 2a of the door-end side panel body 2. and a visible piece 7e that is bent from the outside edge of the visible piece 7d so as to fit along the exterior side surface 2b of the front-end panel body 2, and a pair of front and rear intermediate support pieces 7f that are formed between the interior locking piece 7a and the exterior support piece 7c.The door is configured so that it can be attached to the trailing edge of the front-end panel body 2 that faces the front edge of the door body 4 by screwing a screw 7g inserted between the front and rear intermediate support pieces 7f of the tip side surface portion 7b into the front-end panel body 2. The projection piece 7e of the edge main body 7 is formed with a fitting piece 7h for fitting and incorporating the swing support shaft 8a of the extension 8.

[0011] On the other hand, the extension portion 8 is composed of the swing support shaft 8a, a visible piece portion (outdoor side surface portion) 8b that extends from the swing support shaft 8a in a manner extending the outdoor side surface 2b of the door front panel body 2 toward the door tail side, a visible piece portion (outdoor side surface portion) 8d that is folded back so that the tip edge of the visible piece portion 8b becomes the tip edge portion 8c of the extension portion 8, leaving a gap S between it and the tip side surface portion 5b of the door body side edge member 5, and extends toward the indoor side while following the arc surface of the tip side surface portion 5b to reach the tip side surface portion 7b of the edge main body portion 7, and a folded piece portion 8e that is folded from the indoor side end edge of the visible piece portion 8d toward the door front and faces the outdoor support piece portion 7c of the edge main body portion 7.

[0012] The extension portion 8 configured in this manner is configured to be able to swing between a normal position in which the bent piece portion 8e faces the outside support piece portion 7c of the edge main body portion under normal conditions, and an allowable position in which the tip edge portion 8c swings back toward the outside of the room using the swing support shaft 8a as a support shaft, allowing the deformation of the outside of the door body side edge member 5. In the normal position, the extension portion 8 is maintained in the normal position by the locking protrusion 8ea formed on the bent piece portion 8e being forcefully engaged with the locking receiving portion 7ca formed on the edge main body portion outdoor support piece portion 7c.

[0013] On the other hand, a restricting member 13 is provided at the upper edge on the door leading side of the door body 4 to restrict the door body 4 from inadvertently moving open to the outside when the door body 4 is performing normal opening and closing operations. The restricting member 13 is composed of an attachment part 13b attached to the upper edge on the door leading side of the door body 4 with a screw 13a, a support part 13c suspended from the inside end of the attachment part 13b so as to align with the inside surface of the door body 4, a locking part 13d whose lower end is attached to a spindle 13ca provided on the support part 13c so as to be freely swingable up and down and movable left and right, and a coil spring 13e which urges the locking part 13d which has moved left and right towards its original position. In the normal state in which the door body 4 swings open and closed toward the inside of the room, the regulating member 13 is in a regulating position in which the engagement hole 13da formed in the engagement portion 13d is engaged with the engagement protrusion 13ba formed in the mounting portion 13b, and in this regulating position, the engagement portion 13d stands up and is positioned above the door body 4, suspended over the entrance E, and engages with the rail material 14 provided on the door front and door rear panel bodies 2, 3 from the inside of the room, thereby regulating the opening of the door body 4 toward the outside of the room. In such a normal state, in an emergency where the door body 4 cannot be opened to the inside of the room due to a person inside the room falling or the like, and it becomes necessary to open the door body 4 to the outside of the room in an emergency, the locking portion 13d can be moved left and right against the coil spring mechanism 13e with a finger inserted between the rail material 14 and the upper edge of the door body 4, and the locking protrusion 13ba will come out of the locking hole 13da, thereby allowing the locking portion 13d to assume a collapsed position and releasing the restriction on opening the door body 4 to the outside of the room.

[0014] A specific description will be given of a case where the door body 4 is opened toward the outside of the room in a state where the restriction on opening the door body 4 toward the outside of the room has been released in this way. First, when the door body 4 is operated to open toward the outside of the room, the extension portion 8 receives a load when the middle portion in the front-to-rear direction of the tip side surface portion 5b of the door body side edge member 5 abuts against the extension portion 8, and in conjunction with the locking protrusion 8ea coming out of the locking receiving portion 7ca, the extension portion 8 swings toward the outside of the room around the swing support shaft 8a as its axis, thereby going through a door body opening process in which the door body 4 swings and changes its shape to an allowable position that allows movement toward the opening side, so that the door body 4 can be opened toward the outside of the room. On the other hand, to close the door body 4 that has been opened to the outside of the room, first a door body closing process is carried out to close the door body 4 that has been opened to the outside of the room, and then the extension part in the allowable position is swung back to its original position.By configuring the door body 4 in this way, it is possible to easily open and close the door body 4 to the outside of the room, which is not normally done.

[0015] In the embodiment of the present invention configured as described above, when the door body edge member 5 provided on the door body and the panel body edge member 6 provided on the door tip panel body have a tip side surface 5b of the door body edge member 5 that is a bulging surface that bulges out toward the center in the front-to-rear direction, and an extension portion 8 is provided on the outdoor end edge of the panel body edge member 6 to extend toward the door body edge member 5 and close the gap S between the two edge members 5, 6, the panel body edge member 6 is divided into an edge main body portion 7 and an extension portion 8, The divided extension portion 8 is configured to be able to swing freely so as to allow the door body 4 to be opened to the outside by swinging to the outside in conjunction with the abutment of the door body edge member 5 when the door body 4 is operated to open to the outside of the room.As a result, the extension portion 8 does not need to be made of a deformable flexible member to allow the door body 4 to be opened to the outside of the room, and can be made of a hard member equivalent to the edge members 5, 6.As a result, the extension portion cannot be pried open from the outside of the room to see inside, improving security.

[0016] Moreover, in this case, the divided extension portion 8 comprises a swinging support shaft 8a that is pivotally supported on the edge main body portion 7 so as to be swingable, a visible piece portion 8b that extends from the swinging support shaft 8a in a state of being in contact with the exterior side surface 2b of the panel body 4, a front edge portion 8d that has a tip edge portion 8c of the visible piece portion 8b as its apex and extends from the tip edge portion 8c to the interior side in a state of being in contact with the front side surface portion 5b of the door body side edge member 5, and a front edge portion 8d that extends from the interior tip edge of the visible piece portion 8d to the door end side panel body 2. and a bent piece portion 8e bent in a direction perpendicular to the door frame 1, and a locking portion 8ea formed on the bent piece portion 8e is locked in a forced fit with a locking receiving portion 7ca formed on the edge main body portion 7. As a result, when the extension portion 8 swings outside the room, it easily changes shape in conjunction with the abutment of the door body side edge member 5, allowing the door body to swing outside the room, but it cannot easily change shape from the outside room side to the allowing position, which further improves security.

[0017] Of course, the present invention is not limited to the above-described embodiment, and the forced-fit locking structure between the locking portion 8ea and the locking receiving portion 7ca can also be configured in such a way that the locking portion is formed on the edge main body portion 7 side and the locking receiving portion is formed on the extension portion 8 side. Furthermore, when returning the door body 4 that has opened to the outside of the room and the extension portion 8 that has been transformed to the outside of the room to their original positions, in the above embodiment, the door body 4 is closed and then the extension portion is returned to its original position. However, it is also possible to provide a locking portion on the inside of the room at the tip side portion 5b of the door body side edge member 5, which will come into contact with the extension portion 8 when the door body 4 is closed, thereby allowing the extension portion 8 to return to its original position in conjunction with the closing operation of the door body 4, improving operability. [Industrial Applicability]

[0018] The present invention can be used as an inward-opening door device that is attached to the entrance of a room such as a toilet booth, and as a method for opening and closing the door device to the outside of the room. [Explanation of symbols]
