[Modes for carrying out the invention]

[0008] (First Embodiment) Hereinafter, an embodiment in which the present invention is applied to an aircraft lavatory unit will be described. As shown in FIG. 1 and FIG. 2, the frame of the aircraft lavatory unit 10 includes a floor plate 1002, a front wall 1004 and a rear wall 1006 that stand upright from the floor plate 1002 and face each other, a pair of side walls 1008 that stand upright from the floor plate 1002 and connect both sides of the front wall 1004 and the rear wall 1006, and a ceiling 1010. A toilet bowl 1012 is provided at a position on the floor plate 1002 near the rear wall 1006, a washstand 1014 is provided on one side wall 1008 of the pair of side walls 1008, and the interior of the frame serves as a lavatory 10A. An entrance 12 is provided between a left front wall 1020, which is a portion of the front wall 1004 connected to the one side wall 1008 on which the washstand 1014 is provided, and a right front wall 1022, which is a portion of the front wall 1004 connected to the other side wall 1008, and a door body 14 for opening and closing the entrance 12 is provided.

[0009] As shown in FIG. 1, FIG. 2 and FIG. 7, the opening and closing structure for the entrance 12 of the aircraft lavatory unit 10 is configured to include the door body 14, an operation member 16 for opening and closing the door body, and a locking mechanism 18. The door body 14 has a rectangular plate shape whose vertical height is greater than its width. As shown in FIG. 5, the door body 14 is composed of a plate-shaped core material 1402, and surface materials 1404 made of fiber-reinforced resin arranged on both sides of the core material 1402. One end in the width direction of the door body 14 serves as a hinge mounting end 1410 that is attached to the left front wall 1020 of the lavatory 10A that partitions the entrance 12 via the hinge 20 shown in FIG. 1. The other side in the width direction of the door body 14 serves as a free end 1412 in which a part of the locking mechanism 18 is incorporated and which is mated with the right front wall 1004 that partitions the entrance 12. The door body 14 is swingably mounted so as to open from the entrance 12 to the outside of the lavatory 10A with the support shaft of the hinge 20 as a fulcrum. In many cases, as shown in Figure 1, a non-illustrated screw recoil spring that biases the door body to the closed position for closing the entrance is provided in the restroom, and a non-illustrated damper is also provided in the restroom to mitigate impact noise when closing the entrance, so that if the wrist or elbow is released from the open position of the door body shown in Figure 2, the door body automatically returns to the closed position.

[0010] As shown in Figure 5, Figure 6 and Figure 7, the locking mechanism including the door opening / closing operation member is configured as a unit, and the locking mechanism is incorporated on the free end side of the door body. The locking mechanism includes a pair of face plates facing each other, a pair of door opening / closing operation members, and a latch supported by the pair of face plates so as to be linearly movable.

[0011] As shown in Figure 7, the pair of face plates are made of, for example, fiber-reinforced resin, and slide grooves for supporting the door opening / closing operation member so as to be linearly movable are formed on the respective outer surfaces of the pair of face plates. On the inner surface of one of the pair of face plates, a pair of first guides for guiding the latch so as to be linearly movable are provided, boss portions are provided at four corners of the inner surface, and screw insertion holes are formed at four corners of the other face plate. Further, a back wall extending in a direction orthogonal to the extending direction of the first guides is provided at an end portion of the inner surface of the one face plate away from the free end, and a spring mounting shaft is provided at the center of the back wall. Elongated holes for supporting the pair of door opening / closing operation members so as to be movable between a locking position L and an unlocking position U are formed in the pair of face plates. The locking position L and the unlocking position U are located at positions separated from each other along the surface of the door body. Specifically, the locking position L and the unlocking position U are located at positions separated from each other on a single straight line on the surface of the door body, and the door opening / closing operation member is provided so as to be linearly movable between the locking position L and the unlocking position U. The locked position L and the unlocked position U are both located near the free end 1412 of the door body 14, with the locked position L being located closer to the free end 1412 than the unlocked position U in the width direction of the door body 14.

[0012] The latch 24 consists of a latch body 2402 and a latch portion 2404 that protrudes from the latch body 2402. The latch body 2402 has a rectangular plate shape, with a latch portion 2404 provided on one of the two opposing sides of the latch body 2402, and a spring mounting shaft 2212 protruding from the other side. The latch body 2402 is supported so as to be able to move linearly between a locked position L and an unlocked position U, with its movement in the height direction restricted by a pair of first guides 2204 and its movement in the thickness direction of the door body 14 restricted by the inner surfaces of a pair of surface plates 22. Furthermore, a biasing member 26 made of a coil spring is provided extending from the back wall 2210 to the spring mounting shaft 2212 provided on the latch body 2402. The biasing member 26 constantly biases the latch portion 2404 in the direction that engages with the latch engagement hole 28, and also constantly biases the door opening / closing operating member 16 to the locked position L.

[0013] As shown in Figures 5 and 6, the pair of surface plates 22 are assembled with a latch 24 sandwiched between the pair of first guides 2204. That is, as shown in Figure 7, the pair of surface plates 22 are assembled by screwing screws (not shown) inserted through screw insertion holes 2208 at the four corners of the other surface plate 22 into the female threads of the boss portions 2206 at the four corners of the first surface plate 22. The latch portion 2404 can engage with and disengage from a latch engagement hole 28 provided in the second wall portion, which is the right front wall 1004. The latch portion 2404 is formed with a curved surface on the side facing the restroom 10A and a flat surface on the outside of the restroom 10A, and is configured so that when the door body 14 returns from the open position to the closed position by a screw recoil spring (not shown), the latch portion 2404 automatically engages with the latch engagement hole 28. Furthermore, a stopper wall 1024 is provided on the right front wall 1022 to prevent the door 14 from moving into the interior of the restroom 10A.

[0014] As shown in Figures 5 and 6, the pair of door opening and closing operating members 16 have a thickness along the thickness direction of the door body 14 so that a wrist or elbow can be engaged with them and the door opening and closing operating members 16 can be moved from the locked position L to the unlocked position U by the wrist or elbow. The pair of door opening and closing operating members 16 each have an operating member body 1602 that is linearly movable and coupled to the slide grooves 2202 of the pair of surface plates 22, and a protruding plate portion 1604 that is projected from the end of the operating member body 1602 away from the slide grooves 2202 toward the free end 1412. As shown in Figures 5 and 6, with the locking unit assembled to the door body 14, an open recess 1606 is formed between the protruding plate portion 1604 and the surface plate 22 of the pair of door body opening / closing operating members 16, on the free end 1412 side. This makes it easier to engage the wrist or elbow with the door body opening / closing operating member 16 when moving the door body opening / closing operating member 16 from the locked position L to the unlocked position U. The recess 1606 may be provided only on the door opening / closing operating member 16 without using the surface plate 22.

[0015] With the operating member bodies 1602 of the pair of door opening / closing operating members 16 coupled to the slide groove 2202, a bolt B1 is inserted through the counterbore bolt insertion hole 1608 of one of the pair of door opening / closing operating members 16, passes through the elongated holes 2214 of the pair of surface plates 22 and the bolt insertion hole 2410 of the latch body 2402, and is screwed into the female thread 1610 of the other door opening / closing operating member 16. As a result, the pair of door opening / closing operating members 16 and the latch 24 are connected to the bolt B1, and the pair of door opening / closing operating members 16 and the latch 24 move together as a single unit. When the shaft of bolt B1 abuts against the free end 1412 side of the elongated hole 2214 of the surface plate 22, the door opening and closing operating member 16 is in the locked position L, and the latch 24 is in the locked position L, connected to the latch engagement hole 28. Furthermore, when the shaft of bolt B1 abuts against the end of the elongated hole 2214 of the surface plate 22 that is away from the free end 1412, the door opening and closing operating member 16 is in the unlocked position U, and the latch 24 is in the unlocked position U, disengaged from the latch engagement hole 28.

[0016] The locking unit, which incorporates a pair of surface plates 22, a pair of door opening / closing operating members 16, and a latch 24, is positioned inside a rectangular cutout 30 that is open on the free end 1412 side of the door body 14. The pair of surface plates 22 are fixed inside the cutout 30, for example, with screws or adhesive, and assembled to the door body 14.

[0017] According to this embodiment, even users with impaired hand and finger function who are unable to grip doorknobs or levers can lock their wrists or elbows onto the door opening / closing operating member 16 and move the door opening / closing operating member 16 from the locked position L to the unlocked position U. Then, once the door opening / closing operating member 16 is in the unlocked position U, the door 14 can be swung outwards from the restroom 10A by using the wrist or elbow that is locked to the door opening / closing operating member 16. Therefore, even users with impaired hand function who are unable to grasp, rotate, or swing conventional door opening and closing operating members 16 such as knobs or levers can open and close the entrance 12 using the door 14, and can easily use the aircraft lavatory unit 10.

[0018] Furthermore, the movement of the door opening / closing operating member 16 from the locked position L to the unlocked position U is linear rather than by conventional rotation or oscillation. The length of this linear movement is also short, less than a few centimeters, as it is sufficient for the stroke of the latch portion 2404 to extend and retract from the end face of the door body 14. Therefore, the movement of the door opening / closing operating member 16 can be easily performed, which is advantageous for easily using the aircraft lavatory unit 10. Furthermore, since the door opening and closing operating member 16 has a thickness that is in line with the thickness direction of the door body 14, it is easy to grip with the wrist or elbow, which is advantageous for easily opening and closing the entrance 12 with the door body 14, and is advantageous for easily using the aircraft lavatory unit 10.

[0019] Furthermore, a biasing member 26 is provided that constantly biases the door opening and closing operating member 16 to the locked position L. In most cases, a screw recoil spring is provided to bias the door body 14 to the closed position that closes the entrance 12, and a damper is also provided to mitigate the impact noise when closing the entrance 12. Therefore, when the door body 14 is opened by moving the door body opening / closing operating member 16 with the neck or elbow, and the wrist or elbow is released from the door body opening / closing operating member 16, the door body opening / closing operating member 16 automatically returns to the locked position L, and the door body 14 automatically returns to the closed position. When the door opening / closing operating member 16 returns to the locked position L, the door 14 returns to the closed position and the entrance 12 is closed. At this time, the latch portion 2404 retracts into the free end 1412 of the door 14, then protrudes from the free end 1412 and retracts into the latch engagement hole 28, maintaining the door 14 in the locked position L, which is advantageous for easily opening and closing the door 14.

[0020] Furthermore, the door opening and closing operating member 16 has an operating member body 1602 and a protruding plate portion 1604 that protrudes from the end of the operating member body 1602 away from the surface of the door body 14 toward the free end 1412. An open recess 1606 is formed between the surface of the door body 14 and the protruding plate portion 1604 on the free end 1412 side, where the wrist or elbow can be locked. This makes it easier to lock the wrist or elbow into the recess 1606, which is advantageous for easily moving the door opening and closing operating member 16 from the locked position L to the unlocked position U.

[0021] Furthermore, the locking position L and unlocking position U of the door opening / closing operating member 16 are both located near the free end 1412 of the door body 14 and are aligned horizontally in the width direction of the door body 14. The unlocking position U is located further from the free end 1412 than the locking position L. Therefore, it is immediately clear that moving the door opening / closing operating member 16 away from the free end 1412 will disengage the latch portion 2404 from the latch engagement hole 28, allowing the door body 14 to swing toward the open position. This is advantageous for easily moving the door opening / closing operating member 16 from the locking position L to the unlocking position U. In this embodiment, the case where there is one door panel 14 has been described, but the door panel 14 can be applied to various conventionally known types of door panels 14, such as folding doors in which two doors are joined together in a foldable manner.

[0022] (Second Embodiment) Next, a second embodiment will be described with reference to Figure 8. In the following embodiments, the same reference numerals are used for parts and components as in the first embodiment, and their descriptions are simplified or omitted. The explanation will focus on the parts that differ from the first embodiment. In the second embodiment, the unlocking position U is set closer to the free end 1412 of the door body 14 than the locked position L, and the locked state is released by moving the door body opening / closing operating member 16 in the width direction of the door body 14 toward the free end 1412. In the second embodiment, the direction of movement of the door opening / closing operating member 16 and the direction of movement of the latch 24 are opposite, so the door opening / closing operating member 16 and the latch 24 are connected by a linear lever 32. In the second and third embodiments, the latch body 2402 of the first embodiment is formed into an elongated plate shape, and a latch portion 2404 having the same shape as that of the first embodiment is formed at the end of the latch body 2402. The lever 32 has a pivot shaft 3202 in the middle section that is pivotably supported by a pair of surface plates 22. A connecting pin 1620 of the door opening / closing operating member 16 is movably coupled to a sliding groove at one end of the lever 32, and a connecting pin 2420 of the latch 24 is movably coupled to a sliding groove at the other end of the lever 32.

[0023] Similar to the first embodiment, the door opening and closing operating member 16 is supported by a pair of surface plates 22 so as to be linearly movable between an unlocked position U and a locked position L arranged horizontally, and the surface plates 22 are provided with stoppers that determine the unlocked position U and the locked position L of the door opening and closing operating member 16. Furthermore, the latch 24 is supported by a pair of surface plates 22 so that it can move between an unlocked position where it is disengaged from the latch engagement hole 28 and a locked position where it is engaged with the latch engagement hole 28. Furthermore, the latch 24 is biased by the biasing member 26 in a direction that engages with the latch engagement hole 28, and the door opening / closing operating member 16 is biased by the biasing member 26 or another biasing member to be in the locked position L. Similar to the first embodiment, the locking unit, which incorporates a pair of surface plates 22, a pair of door opening / closing operating members 16, and a latch 24, is positioned inside a rectangular cutout 30 that is open on the free end 1412 side and is provided at a pair of ends of the door body 14 on the free end 1412 side. The surface plates 22 are fixed inside the cutout 30, for example, with screws or adhesive, and assembled to the door body 14.

[0024] In the second embodiment, the door opening / closing operating member 16 is pushed in the width direction of the door body 14 towards the free end 1412, and the door opening / closing operating member 16 is moved linearly horizontally from the locked position L to the unlocked position U, thereby making the door body 14 capable of swinging in the direction of opening the entrance 12. In the second embodiment, in order to make it easier to push the door opening / closing operating member 16 with the wrist or elbow, a recess 1606 is provided at the end of the door opening / closing operating member 16 that is away from the free end 1412, similar to the first embodiment, and is advantageous for easily moving the door opening / closing operating member 16 from the locked position L to the unlocked position U. This second embodiment also produces the same effects as the first embodiment.

[0025] (Third embodiment) Next, a third embodiment will be described with reference to Figure 9. In the third embodiment, similar to the first embodiment, the door opening and closing operating members 16 are located near the free ends 1412 on both sides of the door body 14. However, unlike the first embodiment, the locked position L and the unlocked position U are aligned vertically. As shown in Figure 9(A) where the door opening / closing operating member 16 is located in the locked position L, and in Figure 9(B) where the door opening / closing operating member 16 is located in the unlocked position U, the unlocked position U is located below the locked position L, and the door opening / closing operating member 16 moves back and forth linearly on a vertical line between the locked position L and the unlocked position U. In the third embodiment, since the direction of movement of the door opening / closing operating member 16 and the direction of movement of the latch 24 are perpendicular, the door opening / closing operating member 16 and the latch 24 are connected by a V-shaped lever 34. The lever 34 has a pivot shaft 3402 in the middle section that is pivotably supported by a pair of surface plates 22. A connecting pin 1620 of the door opening / closing operating member 16 is movably coupled to a sliding groove at one end of the lever 34, and a connecting pin 2420 of the latch 24 is movably coupled to a sliding groove at the other end of the lever 34.

[0026] Similar to the first embodiment, the door opening and closing operating member 16 is supported by a pair of surface plates 22 so as to be linearly movable between a locked position L and an unlocked position U arranged vertically, and the surface plates 22 are provided with stoppers that determine the locked position L and the unlocked position U of the door opening and closing operating member 16. Furthermore, the latch 24 is supported by a pair of surface plates 22 so as to be movable between an unlocked position where it is disengaged from the latch engagement hole 28 and a locked position where it is engaged with the latch engagement hole 28. The latch 24 is biased by a biasing member 26 in the direction of engaging with the latch engagement hole 28, and the door opening / closing operating member 16 is biased by the biasing member 26 or another biasing member to be in the locked position L. Similar to the first embodiment, the locking unit, which incorporates a pair of surface plates 22, a pair of door opening / closing operating members 16, and a latch 24, is positioned inside a rectangular cutout 30 that is open on the free end 1412 side and is provided at a pair of ends of the door body 14 on the free end 1412 side. The surface plates 22 are fixed inside the cutout 30, for example, with screws or adhesive, and assembled to the door body 14.

[0027] In the third embodiment, the door opening / closing operating member 16, which is located in the locked position L, is pushed vertically downward along the door body 14, and the door opening / closing operating member 16 is moved linearly vertically from the locked position L to the unlocked position U, thereby making the door body 14 swingable. In the third embodiment, a recess 1606 similar to that in the first embodiment is provided at the upper end of the door opening / closing operating member 16 to make it easier to push the door opening / closing operating member 16 with the wrist or elbow, which is advantageous for easily moving the door opening / closing operating member 16 from the locked position L to the unlocked position U. This third embodiment also produces the same effects as the first embodiment. In the third embodiment, the unlocking position U of the door opening / closing operating member 16 may be set above the locked position L. However, setting the unlocking position U below the locked position L, as in the embodiment, is advantageous in that the door 14 can be opened simply by pushing the door opening / closing operating member 16 downwards.

[0028] In this embodiment, the application of the present invention to an aircraft restroom unit 10 has been described, but the present invention can be widely applied to various restrooms installed in vehicles such as trains, as well as in office buildings, amusement parks, exhibition halls, and the like.
