Description

[Technical Field]

[0001] The present invention relates to a door for opening and closing an entrance to a private room and a private room equipped with the door. [Background technology]

[0002] Inward-opening doors are known as doors installed at the entrances of private rooms such as toilets. They are positioned inside the left and right sleeve panels that form the entrance (inside the room). Inward-opening doors are designed to operate (rotate in the opening and closing direction) only inside the room and not to protrude outside.

[0003] In a private room, a user may suddenly fall ill and collapse, and in such a case, it is necessary to be able to open the door from the outside and rescue the user. As an invention that allows an inward-opening door to be opened (pulled out) to the outside in an emergency, an invention related to a hinge that holds the door has been proposed (for example, Patent Document 1). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2023-177424 Summary of the Invention [Problem to be solved by the invention]

[0005] In some conventional products, the door that opens to the outside of the room interferes with the side panel that makes up the entrance to the private room, making it possible to only open part of the entrance.If only part of the entrance can be opened, it can be difficult to rescue the occupants, and there is still room for improvement in this area.

[0006] The present invention was made in consideration of the above circumstances, and the problem to be solved is to provide a door that does not interfere with the sleeve panel when opened outward in an emergency, and that allows the entrance and exit to be opened wider than with conventional products, and a private room equipped with the door. [Means for solving the problem]

[0007] [door] The door of the present application is a door that opens and closes the entrance to a private room, and is equipped with a first door section that opens and closes part of the entrance, a second door section that opens and closes another part of the entrance, a connecting device that rotatably connects the first door section and the second door section, and a retaining device that holds the first door section and the second door section so that the first door section and the second door section do not rotate independently.

[0008] In the door of the present application, when the holding by the retainer is released, the first door section and the second door section can be configured to rotate in a direction in which the exterior side surfaces, which are the surfaces outside the respective compartments, approach each other.

[0009] In the door of the present application, the connection position of the connector between the first door section and the second door section can be located inside the inner end faces of the left and right sleeve panels, which are the end faces on the entrance / exit side of the left and right sleeve panels, and at 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 that opens and closes the entrance, and the door of this application is positioned inside the room relative to the left and right sleeve panels that form the entrance, and the first door portion of the door is rotatably connected to either the left or right sleeve panel.

[0011] In the private room of the present application, a lock body is provided on the door edge side of the second door section or on the sleeve panel on the door edge side of the second door section, and when the retention by the retainer is released and the exterior surfaces of the first door section and the second door section rotate in a direction approaching each other, the door edge side of the second door section comes out from between the sleeve panel on the door edge side of the second door section and the lock body, allowing the second door section to be pulled out to the outside through the entrance / exit. [Effects of the Invention]

[0012] In the present application, the first door section and the second door section are configured to be rotatable at the connecting device, so that in an emergency, when the door is opened outward, the door does not interfere with the sleeve panel, allowing the entrance and exit to be opened wider than with conventional products.

[0014] (Embodiment) An example of an 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, in the following description, the door side will be referred to as the front, the left side as the left side, the right side as the right side, and the rear side as the rear, with the toilet seat T as the reference.

[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 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 in front 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 and right sleeve panels 14 and 15, and a door 20 for opening and closing the entrance 16 is provided on the indoor side of the left and right sleeve panels 14 and 15.

[0017] A lock 30 is provided on the interior side. In this embodiment, a mortise lock comprising a lock body 30a and a receiver 30b is used as the lock 30. The lock body 30a is provided on the interior side surface 14b of the left sleeve panel 14, and the receiver 30b is provided on the interior side surface 22b of the second door section 22. The lock 30 may be other than a mortise lock.

[0018] When the door 20 is viewed from outside the compartment 10 as shown in Figure 2(a), the left and right ends of the door 20 are overlapped by the left sleeve panel 14 and the right sleeve panel 15 and are therefore not visible, whereas when viewed from inside the compartment 10 as shown in Figure 2(b), the entire door is visible without any overlapping.

[0019] 3 is an exploded explanatory view of the door 20 of this embodiment. As shown in Fig. 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 section 21 is a narrow, vertically elongated member that constitutes part of the door 20. The first door section 21 is rotatably fixed to the interior side surface 15b of the right sleeve panel 15 by a plurality of hinges 25 (three in the illustrated example) that are spaced apart vertically.

[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, constitutes part of the door 20. The second door section 22 is a vertically rectangular shape with an area that is able to close almost the entire entrance 16, and is rotatably connected to one end side of the first door section 21 in the width direction (the side opposite to the connecting side of the right sleeve panel 15 of the first door section 21) by a connecting device 23.

[0022] The connector 23 rotatably connects the first door portion 21 and the second door portion 22. In this embodiment, a long hinge is used as the connector 23, but the connector 23 may be something other than a long hinge as long as it can rotatably connect the first door portion 21 and the second door portion 22.

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

[0024] By positioning the connector 23 at a position where it does not overlap with both sleeve panels 14, 15, the rotational range of the first door section 21 can be maximized, allowing the entrance / exit 16 to be opened widely.

[0025] The holder 24 is a member that holds the first door portion 21 and the second door portion 22 so that they do not rotate independently. As shown in Fig. 4, the holder 24 in this embodiment is a trough-shaped member that is U-shaped in end view and covers the first door portion 21, the second door portion 22, and the connector 23.

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

[0027] As shown in Figure 4, by attaching the upper retaining device 24 to the top of the first door section 21, the second door section 22 and the connecting device 23 and attaching the lower retaining device 24 to the bottom of the first door section 21, the second door section 22 and the connecting device 23, the exterior sides (mating sides; the same applies below) 21a, 22a and the interior sides 21b, 22b of the first door section 21 and the second door section 22 are kept flush or approximately flush so that the first door section 21 and the second door section 22 do not rotate independently and function as a single door as shown in Figures 5(a) and (b).

[0028] On the other hand, when the attached retainers 24 are removed and the retention by the retainers 24 is released, the first door section 21 becomes rotatable in a direction in which the door tip side moves toward the interior of the room, and the second door section 22 becomes rotatable in a direction in which the door tip side moves toward the exterior of the room. In other words, the first door section 21 and the second door section 22 become rotatable in a direction in which their respective exterior sides 21a, 22a approach each other.

[0029] In this embodiment, when the retention device 24 is released and the exterior surfaces 21a, 22a of the first door section 21 and the second door section 22 rotate in a direction approaching each other, the door edge side of the second door section 22 comes out from between the door edge side sleeve panel of the second door section 22 (in this embodiment, the left sleeve panel 14) and the lock body 30a, and the second door section 22 can be pulled out to the outside through the entrance / exit 16.

[0030] The configurations of the first door section 21, the second door section 22, the connecting device 23 and the holder 24 described here are just examples, and the configurations of the first door section 21, the second door section 22, the connecting device 23 and the holder 24 may be other than these.

[0031] (operation) Next, the operation of the door 20 of this embodiment will be described. Figure 6(a) shows the state in which the doorway 16 is closed by the door 20. The upper and lower retainers 24 are in a detached state. From this state, when a force is applied to the connector 23 from the outside toward the inside of the room (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] Thereafter, the first door section 21 and the second door section 22 are further rotated as shown in Figure 6(c) until the end of the second door section 22 on the door front side is released from between the left sleeve panel 14 and the lock body 30a, and the second door section 22 can be pulled outward (opened outward) from the entrance 16 as shown in Figure 6(d).

[0033] After the front end of the second door section 22 is released from between the left sleeve panel 14 and the lock body 30a as shown in Figure 6(d), pulling the second door section 22 further outward as shown in Figure 6(e) opens almost the entire entrance / exit 16, making it possible to carry anyone inside out.

[0034] (Other embodiments) Although the holder 24 of the above embodiment is not provided, a locking mechanism can be provided on the holder 24 so that it can be removed only in an emergency. In this way, the holding by the holder 24 can be prevented from being released inadvertently.

[0035] In the above embodiment, the private room 10 is a toilet booth as an example, but the private room 10 may be a changing room, a shower booth, a bathroom, or the like, other than a toilet booth.

[0036] In the above embodiment, the lock body 30a is provided on the interior side surface 14b of the left sleeve panel 14 as an example, 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 receiver 30b can be provided on the interior side surface 14b of the left sleeve panel 14.

[0037] In the above embodiment, the door 20 is rotatably mounted on the right sleeve panel 15, but the door 20 can also be rotatably mounted on the left sleeve panel 14. In this case, the left and right sides are reversed from the above embodiment. That is, the first door portion 21 is located on the left sleeve panel 14 side, and the second door portion 22 is located on the right sleeve panel 15 side.

[0038] In the above embodiment, the holder 24 has a structure that covers the upper and lower ends of the first door portion 21 and the second door portion 22, but a locking device as shown in Fig. 7 can also be used for the holder 24. The number of locking devices is not limited to one, and two or more can also be provided.

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

[0040] One of the fixed side part 241a and the movable side part 241b is fixed to one of the first door section 21 and the second door section 22, and the other is fixed to the other of the first door section 21 and the second door section 22. As shown in Figures 9 and 10, here, an example is taken where the fixed side part 241a is fixed to the first door section 21 and the movable side part 241b is fixed to the second door section 22, but it is also possible to fix the movable side part 241b to the first door section 21 and the fixed side part 241a to the second door section 22.

[0041] 7 includes a fixed portion 241c that is fixed to the first door portion 21, and a hook receiving portion 241d that protrudes from the fixed portion 241c. The hook receiving portion 241d is a portion that engages with a hook 241h (FIGS. 12(a) to (c)) of the movable part 241b.

[0042] The movable part 241b includes 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 (FIGS. 12(a) to 12(c)).

[0043] This locking device rotates the operating lever 241f in the upright direction to engage the hook 241h of the locking body 241g with the hook receiving portion 241d, and then rotates the operating lever 241f in the downright direction while maintaining that state, causing the hook 241h to engage with the hook receiving portion 241d and lock, and the first door section 21 and the second door section 22 are held in a state where they cannot rotate (cannot rotate individually).

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

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

[0046] The casing 242a is a roughly horizontally U-shaped member having an upper surface portion 242f, a back surface portion 242g, and a lower surface portion 242h, and two shaft support portions 242i and 242j are provided at a distance between the upper surface portion 242f and the lower surface portion 242h, protruding in a direction intersecting the upper surface portion 242f and the lower surface portion 242h.

[0047] Through holes 242k and 242m are formed in both shaft support portions 242i and 242j. A spring support shaft 242n is inserted through both through holes 242k and 242m. A coil spring is provided on the outer periphery of spring support shaft 242n at a position inside both shaft support portions 242i and 242j, as pressing elastic body 242b biased in the extension direction. Both ends of the coil spring abut against the opposing inner surfaces of both shaft support portions 242i and 242j, preventing it from slipping out of both through holes 242k and 242m.

[0048] Inwardly protruding support protrusions 242p, 242q are provided on an upper surface 242f and a lower surface 242h of the casing 242a. In this embodiment, screws are used as the support protrusions 242p, 242q, but the support protrusions 242p, 242q may also be configured with something other than screws.

[0049] A torsion spring is held by both support protrusions 242p, 242q as a spring-up device 242c. The spring-up device 242c is a member for springing up the operating lever 241f of the lock body 241 in the upright direction (toward the interior side when attached to the interior side surface of the door 20). As long as this function and effect can be achieved, various elastic bodies other than a torsion spring can also be used for the spring-up device 242c.

[0050] A pusher insertion hole 242r, through which a pusher 242d (described later) is inserted, is provided in a back surface 242g of the casing 242a. A body portion 242s of the pusher 242d is fitted in the pusher insertion hole 242r. The pusher 242d inserted into the pusher insertion hole 242r is pivotally supported by a pivot pin 242t inserted from the side.

[0051] As shown in Fig. 8, the pusher 242d is a columnar member including a body 242s and a head 242u provided at the tip of the body 242s. The body 242s is provided with an insertion hole 242v penetrating in the left-right direction. This hole is an elongated hole extending in the longitudinal direction of the body 242s. The head 242u of the pusher 242d is provided with an abutment surface 242w that abuts against the abutment receiving surface 243c formed on the lever holder 242e.

[0052] The pusher 242d is supported by having both ends of a shaft pin 242t inserted through an insertion hole 242v of the body portion 242s engaged with a back surface portion 242g of the casing 242a. The pusher 242d moves to the inside of the room when pushed from the outside of the room to the inside of the room by an operating tool X (FIGS. 12(a) to (c)) inserted through an insertion hole (operation hole) 22c of the second door portion 22, and the lever holder 242e pushed by the pusher 242d slides.

[0053] The lever holder 242e is a member that holds the operating lever 241f of the locking device so that the operating lever 241f does not rotate. As shown in Fig. 8, the lever holder 242e includes a base 243a having an opening 243b, a contact receiving surface 243c that rises 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] Opening 243b provided in base 243a is a horizontally rectangular shape, and is a portion through which one shaft support portion 242i of casing 242a and pusher 242d pass. Contact receiving surface 243c is a portion with which contact surface 242w of pusher 242d comes into contact, and is protruded at a position that overlaps opening 243b, in other words, a position where contact surface 242w of pusher 242d that has passed through opening 243b hits.

[0055] The first locking portion 243d is a portion that fits over an internal frame 241i (FIG. 11(a), FIGS. 12(a) to 12(c)) provided inside an operating lever 241f of the locking device, and the second locking portion 243e is a portion that fits over the tip of the free end side of the operating lever 241f. When the first locking portion 243d and the second locking portion 243e are fitted in their respective predetermined positions, the operating lever 241f will no longer rotate in the opening direction (standing direction), and the closed state will be maintained.

[0056] In normal use of the locking device configured as described above, the operating lever 241f is tilted in the closing direction with the hook 241h of the locking body 241 engaged with the hook receiving portion 241d, and the closed state is maintained 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 a closed state (deposed state), the lever holder 242e is pushed in the locking direction, and the first locking portion 243d and the second locking portion 243e cover the operating lever 241f at predetermined positions, thereby holding the operating lever 241f in the closed state.

[0058] On the other hand, in an emergency, when the pusher 242d is pushed by the operating tool X inserted from outside the room, 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 holding state of the operating lever 241f by the lever holder 242e is released.

[0059] 11(a) to 11(c) and 12(a) to 12(c), when the pusher 242d is pushed toward the inside of the room 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 portion 243d and the second locking portion 243e is released. At this time, the operating lever 241f is flipped up in the standing direction by the action of the flip-up tool 242c, and the hook 241h of the lock main body 241 is released from the hook receiving portion 241d, and the connection between the first door portion 21 and the second door portion 22 is released.

[0060] When the connection between the first door section 21 and the second door section 22 is released, the exterior sides 21a, 22a of the first door section 21 and the second door section 22 can rotate in a direction toward each other, and the door tip side of the second door section 22 comes out from between the left sleeve panel 14 and the lock body 30a, allowing the second door section 22 to be pulled out to the outside through the entrance / exit 16.

[0061] The configuration of the above embodiment is an example, and the configuration of the door 20 and the private room 10 of the present invention is not limited to the configuration of the above embodiment. The configurations of the above embodiment can be appropriately changed, such as replaced, omitted, or added, within the scope that can achieve the intended purpose. [Industrial Applicability]
