The locking confirmation tool 3 is provided with a moving mechanism for moving the protrusion 13 so as to move in and out of the main body 11, and when the toilet user enters and locks the toilet room, a part of the protrusion 13a protrudes from the through hole 12, Further, when the user of the toilet releases the locking of the door 1, the protruding protrusion 13 a is configured to be accommodated in the main body 11.

  Thus, if the main body 11 and the protrusion 13 function as identification means, and a visually handicapped person can confirm the protrusion 13a by touching the lock confirmation tool 3 with his / her hand or the like when using the toilet private room, the door 1 Can be recognized as being locked. Further, the visually handicapped person can recognize that the door 1 is unlocked if the protrusion 13a cannot be confirmed by tactile sense. Thus, the visually handicapped person can determine whether or not the toilet room is being used by the user without knocking or pushing the door 1 of the toilet room. In addition, since the protrusion 13a is visible even if it is away from the door 1, a visually impaired person can also be identified visually. Further, the number of protrusions 13a may be one as long as it can be easily confirmed by touch, and the number is not limited. Further, in the present embodiment, the main body 11 has an elliptical shape with a horizontal width of about 8 cm and a vertical width of about 4 cm. However, the present invention is not limited to this, and other shapes can be used as long as identification is easy.

  Here, as shown in FIG. 3, a locking device 4 is provided on the toilet private room side of the door 1 (hereinafter referred to as the inside of the door), and the door 1 is secured on the private room side (inside) of the toilet private room partition 1a. The tool 5 is fixed. The locking device 4 is held by a holder (symbol 14 in FIG. 4) and is slidable in the direction of the stopper 5 (arrow C direction). When the locking device 4 does not cross the stopper 5, the locking device 4 is locked. When the locking device 4 slides and crosses the stopper 5, the locked state is reached (FIG. 3A) (FIG. 3A). Thus, when the locking instrument 4 slides, it has a structure in which the protrusion 13a appears and disappears by the above-mentioned moving mechanism.

  Next, the locking confirmation tool 3 will be described in detail with reference to FIG. 4A and 4B are schematic views showing a cross section of the locking confirmation tool 3 of FIG. 2, wherein FIG. 4A is a cross-sectional view taken along line AA in FIG. 2A, and FIG. 4B is a cross-sectional view taken along line BB of FIG.

The locking device 4 is held by the holder 14 and is slidable in the locking direction (arrow C direction). The locking device 4 is formed with a rack 4a that meshes with a pinion 21 described later. The holder 14 is fixed to the inside of the door 1 with screws (not shown).

  The locking confirmation tool 3 includes a main body 11 and a protrusion 13 which are provided on the outside of the door 1 and serve as the identification means described above. The protrusion 13 includes a protrusion 13a, a cylindrical portion 13b, a protrusion 13a, and a cylindrical portion. It is comprised by the connection part 13c which connects 13b integrally. The cylindrical portion 13b has a cylindrical shape having a concave portion 23 described later, and the rod-shaped body 22 passes therethrough. The rod-shaped body 22 penetrates the door 1, and the rod-shaped body 22 has a cylindrical shape and the pinion 21 is inserted therein. In addition, a fixture 16 having a U-shaped cross section is fixed in the main body 11, and the projection 13 is in contact with the fixture 16 by the urging force of the spring 15 (see FIG. 4A). )It is in. Therefore, the protrusion 13a is accommodated in the main body 11 when the locking is released.

  When the locking device 4 is slid in the direction of arrow C when the user locks in the toilet private room, the rack 4a meshes with the pinion 21 and functions as a rotating means, and the pinion 21 rotates (arrow D). By this rotation, the rod-like body 22 rotates with the central axis in the longitudinal direction as a support shaft, and the protrusion 13 is pushed out of the initial position and moved as will be described later with reference to FIG. When the protrusion 13 moves, the protrusion 13 a protrudes from the through hole 12. At this time, the spring 15 is pressed and contracted, but the protrusion 13 is locked to the rod-like body 22 as described later so that the protrusion 13 does not return to the initial position ( FIG. 4 (b)).

  Further, when the user slides the locking device 4 in the reverse direction to release the locking, the rack 4a meshes with the pinion 21 and functions as a rotating means, and the pinion 21 rotates in the reverse direction (in the direction opposite to the arrow D). As a result, the rod-like body 22 rotates reversely to release the above-described locking, and the protrusion 13 is biased by the spring 15 to move back to the initial position, and the protrusion 13a is accommodated in the main body 11 (FIG. 4). (A)).

  As described above, the rod-shaped body 22 and the rotating means that functions by meshing the rack 4a and the pinion 21 function as a moving mechanism, and the protrusion 13 can be moved, so that the protrusion 13a can appear and disappear. Thereby, a visually handicapped person can easily identify the locked state of the door 1 from the outside of the toilet room by touch.

Here, the movement mechanism of the protrusion 13 will be described in detail with reference to FIG. 5A and 5B are diagrams showing a mechanism for moving the protrusion 13 shown in FIG. 4. FIG. 5A is a view showing the pinion 21, FIG. 5B is a partially cutaway view showing the rod-like body 22, and FIG. It is a figure which shows the protrusion 13.
The pinion 21 includes a gear 21a, a body 21b, and a foot 21c formed by cutting the body 21b into a prism shape. When the rack 4a meshes with the gear 21a, the body 21b and the foot 21c rotate (in the direction of arrow D).

  The rod-like body 22 has a cylindrical shape in which a cavity 22a is formed in the body 22b. The outer diameter of the cavity 22a is slightly larger than the outer diameter of the body 21b of the pinion 21, and the pinion 21 can be inserted therein. In the cavity 22a, a protrusion 22c for hooking the foot 21c is provided at two opposed positions. For this reason, the foot portion 21 c of the pinion 21 is inserted into the cavity 22 a, and the pinion 21 is caught by the rod-shaped body 22. A locking portion 22d for locking to the protrusion 13 described later is formed on the protrusion 13 side of the rod-shaped body 22.

  A cylindrical recess 23 is formed in the protrusion 13, and a rod-like body 22 is fitted in the recess 23. The recess 23 is provided with a slide portion 24 for the locking portion 22d provided on the rod-like body 22 to slide in a spiral shape to push and move the protrusion 13. The slide part 24 has an inclined spiral surface, and a stopper 25 is provided at the upper end of the slide part 24 for stopping the sliding of the locking part 22d. A flat portion 24 a that is not inclined is formed on the slide portion 24 in the vicinity of the stopper 25.

  With the above configuration, when the locking device 4 is slid and locked, the rack 4 meshes with the gear 21a, so that the pinion 21c rotates about the central axis in the longitudinal direction (arrow D direction) The foot 21c is caught by the protrusion 22c, and the rod-like body 22 rotates in the recess 23 (in the direction of arrow E). At this time, the locking portion 22d rotates while sliding the slide portion 24 to push and move the protrusion 13. Further, when the locking portion 22d reaches the stopper 25, the movement amount of the protrusion 13 becomes maximum, and the protrusion 13a protrudes most from the main body 11. Here, the urging force of the spring 15 is maximized when the locking portion 22d is positioned on the flat portion 24a. However, since the locking portion 22 is locked to the flat portion 24a, the protrusion 13 is naturally positioned at the initial position. Will never return.

When unlocking is further performed, the rack 4a meshes with the gear 21a, so that the pinion 21c rotates in the reverse direction (opposite to the arrow D), the foot 21c is hooked on the protrusion 22c, and the rod-shaped body 22 is moved in the recess 23. Reverse rotation (in the opposite direction to arrow E). At this time, the rod-shaped body 22 rotates reversely while the locking portion 22d slides on the slide portion 24, the protrusion 13 is urged by the spring 15 to move back to the initial position, and the protrusion 13a is moved into the main body 11. Be contained.
Here, in this embodiment, the rod-like body 22 penetrates a through hole (not shown) in the bottom of the recess 23 and the main body 11 to prevent the rod-like body 22 from touching the shaft, but the present invention is limited to this. However, the rod-like body 22 may be structured so as not to penetrate the rod-like body 22 as long as the rod-like body 22 can rotate stably.

  As described above, the locking portion 22d provided on the rod-shaped body 22 slides the slide portion 24 in a spiral shape, so that the rod-shaped body 22 can be moved from the initial position by pushing the protrusion 13 while rotating, Further, the rod-shaped body 22 can be moved back to the initial position while rotating in the reverse direction. Thereby, the protrusion 13a can be made to appear and disappear from the main body 11.
