Description

The present invention relates to the technical field of arc-shaped door devices installed at the entrances and exits of booths (small rooms) such as toilet booths and shower booths.

Nowadays, a so-called arc-shaped door device has been proposed as a door device to be installed at the entrance of a booth such as a toilet booth, in which an arc-shaped door body (door body) is slid left and right along an arc trajectory to open and close the entrance. Since such an arc-shaped door device can be retracted (pulled in) into the room (inside the booth) when the entrance is opened, it has the advantage that the left and right width of the entrance (frontage width) can be made wide while the left and right width of the booth can be made small, compared to a normal sliding door device in which the door body moves linearly left and right.
In the case of an arc-shaped door device in this manner, the arcuate trajectory along which the door body moves when opening and closing is configured so that, at the portion corresponding to the edge position of the entrance/exit side of the front panel body that divides the booth, said edge position is located inside the room. As a result, when the door body is closed, it needs to be received and supported at a position inside the room, closer to the edge position of the entrance/exit side of the front panel body. For this reason, it has been proposed to provide a door stopper that protrudes inside the room at the edge of the front panel body so that the door body is received at a position inside the room, closer to the edge position (see, for example, Patent Document 1).

JP 2019-148136 A

By using the method described in Patent Document 1, the door body, which closes along an arc trajectory, can be received on the interior side of the room rather than the front panel body, but in this case, it is required that the door body abut as close to a right angle as possible to ensure stable reception, and for this reason, the door stop material is structured to protrude on the interior side of the entrance/exit section and towards the inside of the frontage of the entrance/exit section. As a result, there is a problem that the door stop material narrows the opening width (frontage width) of the entrance/exit section and the interior space, and these are the issues that the present invention aims to solve.

The present invention has been made in view of the above-mentioned circumstances and with the objective of solving these problems, and the invention of claim 1 relates to an arc-shaped door device comprising: an arc-shaped door body; front panel bodies on the leading and trailing ends of the door body that are provided at an entrance for entering and exiting a room with the panel surfaces flush with each other ; a suspension rail that guides the door body for opening and closing the entrance along an arc-shaped locus in which, when the door body is in a closed state, the left-right central portion of the door body bulges outward from the flush front panel body and the leading and trailing end edges of the door body extend beyond the exterior panel surface of the front panel body to reach the interior side at the inside of the opening of the entrance; an end member provided at the leading end edge of the door body; and a door stop member that is provided at the front panel body and abuts against the end member to receive the door body when the door body is closed, the end member comprising a main body portion attached to the leading end edge of the door body and a protruding portion protruding from the main body portion toward the exterior side beyond the outer periphery of the arc-shaped locus of the door body, and the door stop member being provided at the front panel body and abutting against the end member when the door body is closed, the end member comprising: a main body portion attached to the leading end edge of the door body; a receiving piece formed on the end member protrudes from the exterior part of the end member toward the exterior side at a right angle to the arcuate locus of the door body, and has a protruding length set to a length that passes over the tip of the door stop material from the exterior side at the frontage side to reach the interior side during the closing process of the door body; and a receiving piece formed on the door stop material protrudes from the interior part of the tip toward the interior side at a right angle to the arcuate locus of the door body so as to abut on the protruding part that passes over the tip of the door stop material to reach the interior side, and has a protruding length set to a length that does not reach the arcuate locus of the exterior door surface of the door body .
The invention of claim 2 is an arc-shaped door device as described in claim 1, characterized in that the receiving piece of the door stopper is formed with a groove-shaped concave portion that is open on the inside of the frontage and has groove side pieces on the inside and outside of the room, and the indoor side groove side piece constitutes the receiving piece.
The invention of claim 3 is an arc-shaped door device as described in claim 2, characterized in that the exterior groove side piece is configured as a regulating piece that abuts the end member protrusion and regulates the movement of the door body in the exterior direction when the closed door body is pushed in a direction different from the arc trajectory.
The invention of claim 4 provides the arc-shaped door device according to claim 3, characterized in that the exterior groove side piece is provided so as to be freely position adjustable in the direction of the arc locus.
A fifth aspect of the present invention provides the arc-shaped door device according to any one of the first to fourth aspects, characterized in that the end member has a main body made of a hard material and a protruding portion made of a soft material.

By adopting the invention of claim 1, when the door body is closed, the end member attached to the leading edge of the door body comes into contact with the door stop material attached to the front panel body and is received. In this case, the protrusion provided on the end member so as to protrude further outside than the outer periphery of the door body comes into contact with the receiving piece provided on the door stop material at a position further outside than the outer periphery of the door body and is received. As a result, there is no need to make the door stop material wide enough to extend to the arcuate trajectory portion of the door body, and it is possible to make it more compact and avoid narrowing the opening width of the entrance and the interior space.
By adopting the invention of claim 2, the indoor side groove side piece of the concave groove portion provided in the door stopper material abuts on the protrusion provided on the end member to become a receiving piece that receives the door body, as a result, the receiving piece acts as a screen to prevent the inside of the room from being seen from the outside, and prevents the door body from inadvertently moving inside the room when it is pushed inside the room, thereby providing excellent crime prevention properties.
By adopting the invention of claim 3, when the closed door body is pushed to the outside of the room, the protrusion abuts against the outside groove side piece of the groove-shaped portion, and the outside groove side piece acts as a restricting piece that restricts the door body from inadvertently moving to the outside of the room, thereby providing excellent anti-theft performance.
By adopting the invention of claim 4, the position of the outdoor groove side piece can be adjusted in the direction of the arc trajectory. As a result, if the distance between the protrusion and the outdoor groove side piece is not aligned, this can be easily adjusted, and damage to the appearance can be easily avoided.
According to the invention of claim 5, the end member has a hard main body and a soft protruding portion, so that the end member can be securely attached to the door body via the hard main body, and the protruding portion functions as a cushioning material if a person hits the protruding portion during the process of closing the door body, which is an advantageous feature.

FIG. 2 is a plan view illustrating the suspension rail of the toilet booth. 1A and 1B are plan views of the main part of the door end portion showing the state before the door body is closed and the state after it is closed. 1A and 1B are plan views of the main parts of the door end portion, showing the closed door body being pushed toward the inside of the room and the outside of the room, respectively. FIG. 11 is a plan view of a main portion showing a door end side portion of a door body according to a second embodiment. 13A and 13B are plan views of the main part of the door end side showing the state in which the outdoor side groove side piece of the door stop material has been moved and adjusted. FIG. 11 is a plan view of a main portion of a door leading side portion of a door body according to a third embodiment.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes a toilet booth, and the toilet booth 1 is provided in a state in which a plurality of toilet booths 1 are adjacent to each other on the left and right, and is provided with front panel bodies 2, 3 on the door end side and the door tail side, which are provided with a left and right gap on the front (front) side to form an entrance (opening) E, and with a side panel body 4 provided at the tip (front end) of the front panel bodies 2, 3 and which separates the front panel bodies 2, 3 from a structural surface W such as a wall at the back end of the toilet booth, forming a rectangular partition in a plan view, all of which are conventional.
In this embodiment, the toilet booths 1 are adjacent to each other on the left and right. In this case, the intermediate front panel bodies 2, 3 at the leading and trailing ends of the side panel body 4 separating adjacent toilet booths 1 are constructed as a single piece that is continuous on the left and right, while the front panel bodies 2, 3 at the ends are constructed as separate pieces. It goes without saying that these configurations can be implemented as appropriate as necessary.

Reference numeral 5 denotes a door body (door body) which has an arc shape in a plan view, and the door body 5 is provided with hanger rollers (suspension rollers) 6 which protrude upward from brackets 6a provided on the upper left and right edges of the door body 5. A suspension rail (hanger rail, guide rail) 7 which is guided by the rolling of the hanger rollers 6 has an arc shape concentric with the arc shape of the door body 5, and the portions corresponding to the edges of the entrance/exit section E of the front panel bodies 2, 3 on the door leading and trailing ends are arranged in a position which extends into the interior side in the front-to-rear direction, and the front edge of the suspension rail 7 extends to the portion facing the front panel body 2 on the interior side, and the trailing end edge is arranged so that it extends deep into the toilet booth 1.
With the suspension rail 7 configured in this manner, as is clear from Figures 2 and 3, when the door body 5 is in a closed position, the left-right central portion of the door body 5 bulges outward beyond the flush front panel bodies 2, 3, and the leading and trailing edge portions of the door body extend beyond the exterior panel surfaces of the front panel bodies 2, 3 on the inside of the opening of the entrance/exit portion and reach the interior side of the room, allowing it to open and close.
The door body 5 is guided by the hanger rollers 6 along the hanging rails 7, so that it can move left and right to open and close along an arc trajectory (the trajectory drawn by the center of the door body 5 in the thickness direction) X between a closed position in which the door-leading edge is located at the edge position of the door-leading front panel body 2, and an open position in which it is located at a position opposite the door-trailing front panel body 3, all in the same manner as in the conventional case.
The suspension rail 7 is supported by the front panel bodies 2, 3 and the side panel body 4 via a bracket 7a, and a handle 8 and a locking operation device 9 are provided on the door end portion of the door body 5.

The door body 5 has the same end member 10 provided on both the leading and trailing edge portions. The end member 10 is configured to include a main body portion 10a which is attached to the leading edge portion of the door body 5 via a fixing member such as a screw (not shown), and a tip portion 10b which is detachably attached to the main body portion 10a. The main body portion 10a is formed using a hard material such as a metal such as aluminum or a hard resin material, and the tip portion 10b is formed by two-color molding of a resin material in this embodiment, so that the inner portion 10c which is attached to the main body portion 10a is hard and the outer portion 10d which covers it is soft.
A ⊂-shaped hollow protrusion 10e is formed on the outer portion 10d of the tip portion 10b of the end member, facing toward the outside of the booth (outside the room) beyond the outer peripheral edge 5a of the door body 5, and protrudes in a direction perpendicular to the arc trajectory X (radial direction).
As is clear from Figure 4, the protrusion 10e protrudes from the exterior side portion of the end member, and the protruding length of the protrusion 10e is set so that the protrusion 10e formed on the end member 10 extends from the exterior side to the frontage side beyond the tip 11b of the door stop material 11 and reaches the interior side during the closing process of the door body.

On the other hand, a doorstop material 11 is provided on the edge of the door-end side front panel body 2 on the side of the entrance/exit area. The doorstop material 11 is made of a metal such as aluminum or a hard material such as a hard resin material, and is formed with a base 11a that abuts against the door-end side front panel body 2 and a tip 11b that protrudes from the base 11a to the inside of the frontage (the entrance/exit E side). The tip 11b is shaped so that the central part 11c of the thickness direction (front-rear direction (indoor/outdoor direction)) of the door-end side front panel body 2 protrudes the most toward the entrance/exit E side, and the part from the central part 11c to the outdoor end 11d is shaped to reach the base 11a in a circular arc. In contrast, the part from the central part 11c of the tip 11b to the indoor end 11h is shaped to reach the base 11a with a groove-shaped part 11e that opens on the frontage side like a groove.

When the door body 5 is closed, the protrusion 10e of the end member 10 provided on the door body 5 is fitted into the groove-shaped portion 11e in the left-right direction. In this case, the protrusion 10e of the end member 10 provided on the door body 5 abuts against the indoor side groove side piece 11f of the groove-shaped portion 11e at a position biased toward the outdoor side from the outer peripheral surface 5a of the door body 5, in other words, at a position biased toward the outdoor side from the arc locus Y traced by the door body outer peripheral surface 5a, at a right angle to the direction of the arc locus X, and receives the door body 5. As a result, the indoor side groove side piece 11f forms a receiving piece 11f for receiving the door body 5.
In this case, when the closed door body 5 is pushed into the interior of the room, the door body 5 will not be biased any further toward the interior of the room because the protruding portion 10e will be maintained in contact with the interior groove side piece 11f. As a result, the interior side of the room will not be visible from the outside of the room. However, as is clear from Figure 4, the protruding length of the receiving piece 11f is set to a length that does not reach the arc trajectory Y of the exterior door surface of the door body.

In contrast, when the door body 5 is closed and the protrusion 10e is in contact with the indoor groove side piece (receiving piece) 11f, the protrusion 10e faces the indoor groove side piece (receiving piece) in a state of overlapping (overlapping) in the front-to-rear direction with a gap S. As a result, when the closed door body 5 is pushed in a direction outside the room that differs from the arc trajectory X, the protrusion 10e comes into contact with the outdoor groove side piece 11g, and the outdoor groove side piece 11g forms a restricting piece 11g that restricts the movement of the door body 5 in the outdoor direction, so that the inside of the room cannot be seen from outside even when the door body 5 is pushed to the outside.

In the present embodiment configured as described above, the entrance E of the toilet booth 1 is opened and closed by the arc-shaped door body 5 being guided by the arc-shaped hanging rail 7 and moving left and right along the arc trajectory. In this case, when the door body 5 is closed, the end member 10 provided on the door end edge of the door body 5 abuts against the door stop material 11 provided on the door end front panel body 2. At this time, the protruding portion 10e provided on the end member 10, which protrudes outside the outer periphery of the door body 5, abuts against the receiving piece portion 11f provided on the door stop material 11 at a position outside the outer periphery of the door body 5, and is received. As a result, the door stop material 11 does not need to be wide enough to extend to the arc trajectory X part of the door body 5, and can be made compact, and it is possible to avoid narrowing the opening width of the entrance E and the interior space.

Furthermore, in this case, the receiving piece 11f is formed in a groove shape at the tip 11b of the door stop material 11, and is formed by the indoor side groove side piece 11f of the groove-shaped portion 11e having both indoor and outdoor groove side pieces 11f, 11g. Therefore, the receiving piece 11f acts as a screen to prevent someone from looking into the indoor side from the outside, and prevents the closed door body 5 from accidentally leaning toward the indoor side when it is pushed toward the indoor side, allowing the inside of the room to be looked into, thereby providing excellent crime prevention properties.
On the other hand, when the closed door body 5 is pushed in a direction toward the outside of the room that is different from the arc trajectory, the protrusion 10e of the end member 10 abuts against the exterior groove side piece 11g, thereby forming a restricting piece 11g that restricts the door body 5 from moving inadvertently in the exterior direction, thereby providing excellent security.

In addition, in this device, the end member 10 provided on the door body 5 has a main body portion 10a that is attached to the door body 5 made of a hard material and a protruding portion 10e that is made of a soft material. This allows the end member 10 to be securely attached to the door body 5 via the hard main body portion 10a, and is ideal in that the protruding portion 10e functions as a shock absorber in the event that a person hits the protruding portion 10e during the process of closing the door body.

Of course, the present invention is not limited to the above-described embodiment, and can be implemented, for example, as the second embodiment shown in FIGS. 6 to 8 and the third embodiment shown in FIG. 9.
In the second embodiment, like the first embodiment, the door stop material 12 has a main body 12a attached to the front panel body 2 and a groove-like portion 12e formed at the tip end 12b, but the groove-like portion 12e is V-shaped and the indoor side groove side piece 12f serves as a receiving piece against which the protrusion 10e provided on the end member 10 abuts when the door body 5 is closed, and the outdoor side groove side piece 12g serves as a restricting piece against which the protrusion 10e abuts to restrict the movement of the door body 5 when the closed door body 5 is pushed towards the outside of the room.
In this embodiment, the outdoor groove side piece 12g is provided on a movable piece 12h whose position is adjusted by a screw 12i in the direction of the arc locus X. By doing so, if the distance (spacing) between the protrusion 10e and the outdoor groove side piece 12g is not uniform, the adjustment can be made by adjusting the screw 12i, and it is possible to easily avoid impairing the appearance.

Furthermore, in the third embodiment, the door stopper 13 is only provided with an interior groove side piece 13f against which the protruding portion 10e of the end member 10 abuts when the door body 5 is closed, and the present invention can be implemented in this way as well.

The present invention can be used as an arc-shaped door device installed at the entrance of a booth (small room) such as a toilet booth or shower booth.
