Specifically, the release groove 47 is formed in an elliptical shape whose longitudinal direction is perpendicular to the straight line connecting the pair of pin insertion holes 44 when viewed from the front and rear directions. The release groove 47 communicates with the depression 45. By forming the release groove 47, a space S is provided behind the restriction portion 46.

(lock pin)
Returning to FIG. 4, the lock pin 50 is configured to be able to move forward and backward into the housing portion 21 through the pin insertion hole 44 of the intervening member 40. Specifically, the lock pin 50 is inserted into the pin insertion hole 44 during normal use, thereby holding the door body 20 in a suspended state from the rail member 6. On the other hand, when it is necessary to remove the door 5 from the outside of the toilet booth 2 in an emergency, the lock pin 50 is removed from the pin insertion hole 44, thereby making it possible to remove the door body 20 from the door support 30. .

The lock pin 50 is formed into a U-shape in plan view, and includes a pair of entry portions 51 and a connection portion 53 that connects the pair of entry portions 51.
A pair of entrance portions 51 are provided on the left and right. The pair of entry portions 51 are inserted into the pair of pin insertion holes 44, respectively. During normal use, the entry portion 51 of the lock pin 50 is inserted into the pin insertion hole 44 of the intervening member 40 and enters the engagement portion 37 of the door support 30 (the engagement state in the claims). ). That is, the entry portion 51 of the lock pin 50 sandwiches the fixing portion 31 of the door support 30 from the left and right sides, and its lower end is engaged with the engaging portion 37 of the fixing portion 31 from above. Thereby, the door body 20 is suspended from the door support 30 via the intervening member 40 and the lock pin 50. That is, the downward movement of the door body 20 with respect to the door support 30 is restricted, and the detachment of the fixing part 31 from the accommodating part 21 is suppressed. Note that the lower end of the entry portion 51 is not necessarily the lowermost end of the lock pin 50. That is, if the door body 20 is suspended and supported by the door support 30 via the lock pin 50, the lower end of any part of the lock pin 50 is engaged with the engaging portion 37 from above. Good too.

The connecting portion 53 is in contact with the restricting portion 46 of the intervening member 40 . Thereby, the insertion depth of the lock pin 50 into the intervening member 40 is regulated. Further, since the connecting portion 53 is disposed within the recess 45, it does not protrude further forward than the intervening member 40.

In the lock pin 50 configured as described above, in an initial state before being inserted into the pin insertion hole 44, the pair of entry portions 51 are formed in an inclined state. Specifically, the entrance portions 51 are inclined so as to be spaced apart from each other as they go from the front end where the connection portion 53 is provided to the rear end on the opposite side to the connection portion 53. In this initial state, the length dimension connecting the rear end portions of the entrance portion 51 is larger than the length dimension connecting the pair of pin insertion holes 44 of the intervening member 40. Therefore, after the lock pin 50 is inserted into the pin insertion hole 44 while being elastically deformed so as to narrow the rear end, the inner wall of the pin insertion hole 44 is pressed outward in the left-right direction by the restoring force. There is.

Further, when the lock pin 50 is inserted into the intervening member 40 from the outer circumferential protrusion 42 side, the connecting portion 53 comes into contact with the regulating portion 46, so that the lock pin 50 is inserted into the inner side (in the front-rear direction) in the insertion direction (front-back direction). Movement to the rear) is restricted.
In this state, the release groove 47 is provided in a portion of the regulating portion 46 that overlaps with the connecting portion 53 of the lock pin 50 when viewed from the axial direction of the main body portion 41 .

(Operating procedure for door device)
Next, the operating procedure of the door device 1 in an emergency will be explained based on FIGS. 4, 5, 9, and 10.

At this time, for example, by inserting a tool such as a flat head screwdriver or a wrench into the release groove 47 of the intervening member 40, and pulling the lock pin 50 toward you using the principle of leverage using the opening edge of the release groove 47 as a fulcrum, The lock pin 50 can be easily removed even with a small force. If a plurality of door supports 30 are provided, all the lock pins 50 of the intervening member 40 into which the door supports 30 are inserted are similarly removed.

By removing the lock pin 50 in this manner, the engagement between the fixing portion 31 of the door support 30 and the intervening member 40 is released, and vertical movement of the door support 30 with respect to the door body 20 is permitted. Ru.
Next, by moving the door body 20 downward (or by moving the door body 20 downward by its own weight), the fixed part 31 of the door support body 30 is completely removed from the inside of the housing part 21. let By detaching the door support 30 from the door body 20, the door support 30 and the door body 20 are separated from each other, so that the door body 20 falls off with respect to the rail member 6. This completes the removal of the door body 20.

Next, the work of reattaching and restoring the removed door body 20 will be described.
When restoring the door 5, the procedure for removing the door body 20 described above is reversed. That is, first, the door main body 20 is lifted and the fixing part 31 is inserted into the accommodating part 21. Next, with the fixing part 31 inserted into the accommodating part 21, the lock pin 50 is inserted into the pin insertion hole 44 of the intervening member 40 from the surface 20s of the door main body 20. At this time, the lock pin 50 is inserted while narrowing the end portion of the lock pin 50. Next, the inserted lock pin 50 and the engaging portion 37 of the fixing portion 31 are engaged with each other. By inserting the lock pins 50 into all the door supports 30, the restoration work of the door 5 is completed.
