Summary of Invention

Problems to be Solved by the Invention

[0005] Among conventional products, there are some in which the door opened to the outdoor side interferes with the side panels constituting the entrance of the private room, so that only a part of the entrance can be opened. If only a part of the entrance can be opened, there is a risk that the rescue of the user will be difficult, and there remains room for improvement in this respect.

[0006] The present invention has been made in view of such circumstances, and the problem to be solved is to provide a door that does not interfere with the side panels when the door is opened outward in an emergency, allowing the entrance to be opened more widely than conventional products, and a private room equipped with the door. [Means for solving the problem]

[0007] [door] The present invention relates to a door for opening and closing an entrance to a private room, comprising a first door section that opens and closes a part of the entrance, a second door section that opens and closes another part of the entrance, a connector that rotatably connects the first door section and the second door section, and a holder that holds the first door section and the second door section so that they do not rotate independently.

[0008] In the door of the present invention, when the holding mechanism is released, the first door section and the second door section can be configured to rotate in a direction that brings their respective exterior surfaces, which are the exterior surfaces of the individual rooms, closer together.

[0009] In the door of this invention, the connection position of the connector between the first door section and the second door section can be set to be inside the inner end face of the sleeve panel, which is the end face on the entrance side of the left and right sleeve panels, and in a position that does not overlap with the left and right sleeve panels.

[0010] [Private Room] The private room in this application is a private room equipped with an entrance and a door for opening and closing the entrance, wherein the door of this application is positioned on the interior side of the left and right side panels that form the entrance, and the first door portion of the door is rotatably connected to either the left or right side panel.

[0011] In the private room of the present invention, the lock body is provided on the leading edge side of the second door or on the side panel on the leading edge side of the second door, and when the holding by the retainer is released and the respective exterior sides of the first and second doors rotate in a direction that brings them closer together, the leading edge side of the second door comes out from between the side panel on the leading edge side of the second door and the lock body, allowing the second door to be pulled out from the entrance. [Effects of the Invention]

[0012] In this invention, the first door section and the second door section are configured to rotate at the connecting part, so that in an emergency, when the door is opened outward, the door does not interfere with the side panel, and the entrance can be opened wider than in conventional products.

Modes for Carrying Out the Invention

[0014] (Embodiment) An example of the embodiment of the door 20 and the private room 10 of the present application will be described with reference to the drawings. Here, the case where the private room 10 is a toilet booth will be described as an example. For convenience, the following description will be made with the toilet seat T as a reference, where the door side is defined as the front, the left side as the left side, the right side as the right side, and the rear side as the rear.

[0015] Figure 1 is a schematic plan view of a private room (toilet booth) 10. As shown in Figure 1, the private room 10 of this embodiment includes a back panel 11, a left side panel 12 and a right side panel 13 arranged so as to surround a toilet seat T, and left and right sleeve panels (hereinafter referred to as "left sleeve panel 14" and "right sleeve panel 15") arranged on the front side of the left side panel 12 and the right side panel 13.

[0016] An entrance 16 for users to enter and exit is formed between the left sleeve panel 14 and the right sleeve panel 15, and a door 20 for opening and closing the entrance 16 is provided on the indoor side of the left sleeve panel 14 and the right sleeve panel 15.

[0017] A lock 30 is provided on the indoor side. In this embodiment, a latch lock including a lock main body 30a and a receiver 30b is used as the lock 30. The lock main body 30a is provided on the indoor side surface 14b of the left sleeve panel 14, and the receiver 30b is provided on the indoor side surface 22b of the second door portion 22. The lock 30 may be a type other than a latch lock.

[0018] When viewed from the outside of the private room 10 as shown in Figure 2(a), the door 20 is in a state where both left and right end sides overlap the left sleeve panel 14 and the right sleeve panel 15 and are not visible, and when viewed from the inside of the private room 10 as shown in Figure 2(b), the entire surface is visible without overlapping.

[0019] Figure 3 is an exploded explanatory view of the door 20 of this embodiment. As shown in Figure 3, the door 20 of this embodiment includes a first door portion 21, a second door portion 22, a connector 23 that connects the first door portion 21 and the second door portion 22, and a holder 24 that holds the first door portion 21 and the second door portion 22.

[0020] The first door portion 21 is a narrow vertically long member that constitutes a part of the door 20. The first door portion 21 is rotatably fixed to the indoor side surface 15b of the right sleeve panel 15 by a plurality of (three in the illustrated example) hinges 25 arranged at vertical intervals.

[0021] The second door section 22 is a vertically elongated member that is wider than the first door section 21, and together with the first door section 21, it constitutes a part of the door 20. The second door section 22 is a vertical rectangle with an area that can close almost the entire entrance 16, and is rotatably connected by a connector 23 to one end of the first door section 21 in the width direction (the side opposite to the connection side of the right side panel 15 of the first door section 21).

[0022] The connecting device 23 rotatably connects the first door section 21 and the second door section 22. In this embodiment, a long hinge is used as one example of the connecting device 23, but the connecting device 23 may be anything other than a long hinge, as long a hinge can rotatably connect the first door section 21 and the second door section 22.

[0023] The connection point of the connector 23 between the first door section 21 and the second door section 22 is inside the inner end faces 14a and 15a of the left and right side panels 14 and 15, which are the end faces on the entrance 16 side of the side panels, and is in a position that does not overlap with the left and right side panels 14 and 15 (a position that is not hidden by the left and right side panels 14 and 15) (see Figures 2(a) and 2(b)).

[0024] By positioning the connector 23 in a location that does not overlap with the side panels 14 and 15, the rotational range of the first door section 21 can be maximized, allowing the entrance 16 to be opened wide.

[0025] The retainer 24 is a member that holds the first door portion 21 and the second door portion 22 so that they do not rotate individually. As shown in Figure 4, the retainer 24 in this embodiment is a trough-shaped member with a U-shape when viewed from the end face that covers the first door portion 21, the second door portion 22 and the connector 23.

[0026] The retaining device 24 is detachably provided above and below the first door section 21, the second door section 22, and the connecting device 23. The retaining device 24 can be fixed with screws or the like, or it can be fixed simply by press-fitting.

[0027] As shown in Figure 4, the upper holder 24 is attached to the upper part of the first door section 21, the second door section 22 and the connector 23, and the lower holder 24 is attached to the lower part of the first door section 21, the second door section 22 and the connector 23. This prevents the first door section 21 and the second door section 22 from rotating individually, and the exterior sides (hereinafter the same) 21a, 22a and interior sides 21b, 22b) of the first door section 21 and the second door section 22 from rotating individually, so that they function as a single door as shown in Figures 5(a) and (b). The exterior sides (hereinafter the same) 21a, 22a and the interior sides 21b, 22b of the first door section 21 and the second door section 22 are held flush or nearly flush.

[0028] On the other hand, when the attached retainers 24 are removed and the holding by the retainers 24 is released, the first door section 21 becomes rotatable in a direction where the leading edge moves inward, and the second door section 22 becomes rotatable in a direction where the leading edge moves outward. In other words, the first door section 21 and the second door section 22 become rotatable in a direction where their respective exterior sides 21a and 22a move closer together.

[0029] In this embodiment, when the holding device 24 is released and the exterior sides 21a and 22a of the first door section 21 and the second door section 22 rotate toward each other, the leading edge of the second door section 22 disengages from between the leading edge side panel (left side panel 14 in this embodiment) and the lock body 30a, allowing the second door section 22 to be pulled out from the entrance 16.

[0030] The configuration of the first door section 21, second door section 22, connector 23, and holder 24 described herein is merely an example, and the configuration of the first door section 21, second door section 22, connector 23, and holder 24 may be other than that described herein.

[0031] (operation) Next, the operation of the door 20 in this embodiment will be described. Figure 6(a) shows the door 20 closing the entrance 16. The upper and lower retainers 24 are detached. From this state, when a force is applied to the connector 23 from the outside to the inside (in the direction of the arrow in the figure), as shown in Figure 6(b), the first door section 21 and the second door section 22 rotate from the connector 23.

[0032] Subsequently, as shown in Figure 6(c), the first door section 21 and the second door section 22 are rotated further until the leading edge of the second door section 22 disengages from between the left side panel 14 and the lock body 30a, allowing the second door section 22 to be pulled outwards (open outwards) from the entrance 16, as shown in Figure 6(d).

[0033] As shown in Figure 6(d), after the leading edge of the second door section 22 detaches from the space between the left side panel 14 and the lock body 30a, and then as shown in Figure 6(e), when the second door section 22 is pulled further outward, almost the entire entrance 16 is opened, allowing people inside to be carried out.

[0034] (Other embodiments) Although the above embodiment does not include the holder 24, the holder 24 can be provided with a locking mechanism so that it can be removed only in emergencies. In this way, the holding by the holder 24 can be prevented from being released unintentionally.

[0035] In the above embodiment, the case where the private room 10 is a toilet booth is given as an example, but the private room 10 may be a changing room, shower booth, bathroom, or other type of room besides a toilet booth.

[0036] In the above embodiment, one example is that the lock body 30a is provided on the interior side surface 14b of the left side panel 14, but the lock body 30a can also be provided on the door edge side of the interior side surface 22b of the second door section 22. In this case, the receiving device 30b can be provided on the interior side surface 14b of the left side panel 14.

[0037] In the above embodiment, the case in which the door 20 is rotatably mounted on the right side panel 15 is given as an example, but the door 20 can also be rotatably mounted on the left side panel 14. In this case, the left and right sides will be reversed compared to the above embodiment. That is, the first door section 21 will be located on the left side panel 14 side, and the second door section 22 will be located on the right side panel 15 side.

[0038] In the above embodiment, one example of a retainer 24 is one that fits over the upper and lower ends of the first door section 21 and the second door section 22. However, a locking device as shown in Figure 7 can also be used as the retainer 24. The locking device is not limited to one; two or more can be provided.

[0039] This locking device comprises a lock body 241 and a lock release tool 242. The lock body 241 is a so-called snap lock, and an existing one can be used. As an example, the lock body 241 shown in Figure 7 comprises a fixed part 241a and a movable part 241b.

[0040] The fixed part 241a and the movable part 241b are fixed to one of the first door section 21 and the second door section 22, with the other fixed to the other of the first door section 21 and the second door section 22. As shown in Figures 9 and 10, here we take the case where the fixed part 241a is fixed to the first door section 21 and the movable part 241b is fixed to the second door section 22 as an example, but it is also possible to fix the movable part 241b to the first door section 21 and the fixed part 241a to the second door section 22.

[0041] As an example, the fixed-side part 241a shown in Figure 7 includes a fixed part 241c that is fixed to the first door part 21, and a hook receiving part 241d that protrudes from the fixed part 241c. The hook receiving part 241d is the part to which the hook 241h (Figures 12(a)~(c)) of the movable-side part 241b is engaged.

[0042] The movable part 241b comprises a base seat 241e, an operating lever 241f rotatably connected to the base seat 241e, and a locking body 241g rotatably connected to the operating lever 241f. The locking body 241g is provided with a hook 241h (Figures 12(a)~(c)).

[0043] This locking device works by rotating the operating lever 241f in the upward direction to engage the hook 241h of the locking body 241g with the hook receiving part 241d, and then, while maintaining that state, rotating the operating lever 241f in the downward direction to engage the hook 241h and the hook receiving part 241d, thereby locking them in place and holding the first door section 21 and the second door section 22 in a state where they do not rotate (do not rotate individually).

[0044] On the other hand, the lock is released by the release tool 242. The release tool 242 is attached to the same door section (in this embodiment, the second door section 22) as the movable part 241b.

[0045] As an example, the unlocking device 242 shown in Figures 7 and 8 comprises a casing 242a, a pressing elastic body 242b, a spring-up device 242c, a pusher 242d, and a retainer (hereinafter referred to as "lever retainer") 242e.

[0046] The casing 242a is a generally horizontally oriented U-shaped member having an upper surface portion 242f, a rear surface portion 242g, and a lower surface portion 242h. Between the upper surface portion 242f and the lower surface portion 242h, two shaft support portions 242i and 242j are provided at a distance from each other, projecting in a direction that intersects the upper surface portion 242f and the lower surface portion 242h.

[0047] Through holes 242k and 242m are provided in the double-shaft support sections 242i and 242j. A spring support shaft 242n is inserted through both through holes 242k and 242m. A coil spring, acting as a compression elastic body 242b and biased in the extension direction, is provided on the outer circumference of the spring support shaft 242n at a position inside the double-shaft support sections 242i and 242j. Both ends of the coil spring abut against the opposing inner surfaces of the double-shaft support sections 242i and 242j, preventing them from coming out of the double through holes 242k and 242m.

[0048] The upper surface 242f and lower surface 242h of the casing 242a are provided with inwardly projecting support protrusions 242p and 242q. In this embodiment, screws are used as the support protrusions 242p and 242q, but the support protrusions 242p and 242q can be made of materials other than screws.

[0049] Torsion springs, acting as the flip-up mechanism 242c, are held by both support protrusions 242p and 242q. The flip-up mechanism 242c is a component for flipping up the operating lever 241f of the lock body 241 in the upright direction (towards the interior when attached to the interior side of the door 20). Various elastic bodies other than torsion springs can be used for the flip-up mechanism 242c, as long as they can achieve this effect.

[0050] The rear portion 242g of the casing 242a is provided with a pusher insertion hole 242r through which a pusher 242d, described later, is inserted. The body portion 242s of the pusher 242d is fitted into the pusher insertion hole 242r. The pusher 242d, inserted through the pusher insertion hole 242r, is pivotally supported by a shaft pin 242t inserted from the side.

[0051] As shown in Figure 8, the pusher 242d is a columnar member comprising a body portion 242s and a head portion 242u provided at the tip of the body portion 242s. The body portion 242s is provided with an insertion hole 242v that penetrates in the left-right direction. This hole is an elongated hole in the longitudinal direction of the body portion 242s. The head portion 242u of the pusher 242d is provided with a contact surface 242w that contacts the contact receiving surface 243c formed on the lever holder 242e.

[0052] The pusher 242d is supported by the fact that both ends of the shaft pin 242t, which is inserted through the insertion hole 242v of the body portion 242s, are locked to the rear portion 242g of the casing 242a. The pusher 242d moves to the interior side when pushed from the exterior side to the interior side by an operating tool X (Figure 12(a)~(c)) inserted through the insertion hole (operating hole) 22c of the second door portion 22, causing the lever holder 242e, which is pushed by the pusher 242d, to slide.

[0053] The lever holder 242e is a member that holds the operating lever 241f so that the operating lever 241f of the locking device does not rotate. As shown in Figure 8, the lever holder 242e includes a base 243a with an opening 243b, a contact receiving surface 243c rising from the base 243a, a first locking portion 243d provided on one end of the base 243a, and a second locking portion 243e provided on the other end of the base 243a.

[0054] The opening 243b provided in the base 243a is horizontally rectangular and is the part through which one shaft support portion 242i of the casing 242a and the pusher 242d are inserted. The contact receiving surface 243c is the part that the contact surface 242w of the pusher 242d contacts, and is positioned over the opening 243b, in other words, it is provided protruding at the position where the contact surface 242w of the pusher 242d, after passing through the opening 243b, abuts against it.

[0055] The first locking portion 243d is the part that covers the internal frame 241i (Figures 11(a), 12(a)-(c)) located inside the operating lever 241f of the locking device, and the second locking portion 243e is the part that covers the tip of the free end of the operating lever 241f. When the first locking portion 243d and the second locking portion 243e are in their respective predetermined positions, the operating lever 241f is prevented from rotating in the opening direction (upright direction), and the closed state is maintained.

[0056] In the locking device configured as described above, during normal use, the hook 241h of the lock body 241 is engaged with the hook receiving portion 241d, the operating lever 241f is tilted in the closing direction, and the closed state is held by the lever holder 242e of the lock release tool 242 (Figures 10, 11(a), and 12(a)).

[0057] Specifically, when the operating lever 241f is in the closed (downward) position, the lever holder 242e is pushed in the locking direction, and the first locking part 243d and the second locking part 243e cover the predetermined position of the operating lever 241f, thereby holding the operating lever 241f in the closed position.

[0058] On the other hand, in an emergency, when the pusher 242d is pushed by the operating tool X inserted from the outside, the contact surface 242w of the pusher 242d pushes the contact receiving surface 243c, causing the lever holder 242e to move (slide) laterally, and the lever holder 242e releases its hold on the operating lever 241f.

[0059] Specifically, as shown in Figures 11(a)-(c) and 12(a)-(c), when the pusher 242d is pushed inward while the operating lever 241f is held by the lever holder 242e, the lever holder 242e pushed by the pusher 242d slides in the release direction, and the holding of the operating lever 241f by the first locking part 243d and the second locking part 243e is released. At this time, the operating lever 241f is flipped up in the upright direction by the action of the flip-up device 242c, and the hook 241h of the lock body 241 detaches from the hook receiving part 241d, releasing the connection between the first door part 21 and the second door part 22.

[0060] When the connection between the first door section 21 and the second door section 22 is released, the exterior sides 21a and 22a of the first door section 21 and the second door section 22 become rotatable in a direction that brings them closer together, the leading edge of the second door section 22 detaches from between the left side panel 14 and the lock body 30a, and the second door section 22 can be pulled out from the entrance 16.

[0061] The configuration of the above embodiment is merely an example, and the configuration of the door 20 and private room 10 of the present invention is not limited to the configuration of the above embodiment. Each configuration of the above embodiment can be modified as appropriate, such as by replacing, omitting, or adding components, to the extent that the intended purpose can be achieved. [Industrial applicability]
