Therefore, if the proximity switch is attached to the toilet booth like the door at the entrance, the proximity switch is easily damaged by the impact when the door is closed.

Further, the conventional display device for the use state of the toilet booth is based on switching of color plates having different colors, and it is difficult to identify unless the illuminance in the toilet room is sufficiently high. Further, since this color plate is a small one with a side of several cm or less, it is difficult to identify it unless it comes close to the door.

[Means for Solving the Problems] The toilet slide lock according to claims (1) and (2) has a guide fitting fixed to the door, and a lock posture that is guided by the guide fitting and protrudes from the edge of the door. In a toilet slide lock equipped with a slide fitting that is slidably movable between an unlocked posture retracted from the edge, a groove extending in the sliding movement direction on the slide fitting, with a proximity switch provided on the guide fitting. Is provided.

Claim (1) is characterized in that the groove and the proximity switch face each other when the slide metal fitting is in the unlocked posture, and the groove and the proximity switch face each other when the slide metal fitting is in the locked posture.

Claim (2) is characterized in that the groove and the proximity switch face each other when the slide metal fitting is in the lock posture, and the groove and the proximity switch face each other when the slide metal fitting is in the unlock posture.

A toilet booth door according to claim (3) comprises the toilet slide lock according to claim (1) or (2), and a display device illuminated by a proximity switch is provided on the front side of the booth door near the slide lock. It is a thing.

[Operation] In the slide lock according to claims (1) and (2), when the slide fitting is slid to switch the locked state between the locked posture and the unlocked posture, the engagement state between the groove and the proximity switch is switched. To be That is, when the groove and the proximity switch face each other, the proximity switch turns off, and when the groove and the proximity switch do not face each other, the proximity switch turns on.
(Detect proximity). In this way, the protrusion and retreat of the slide fitting are detected by the proximity switch. In the toilet booth, when the user goes inside, the lock is always performed from the inside. Therefore, the slide lock can reliably detect whether or not the toilet booth is used.

In the toilet booth door according to claim (3), the display device is turned on when the slide lock is locked. Therefore, even when the illuminance in the toilet booth is insufficient or when the toilet booth is away from the door, the usage state can be easily identified.
