Description

[Technical field]

[0001] The present invention relates to a door locking device that is installed on a door, a lock and a restricting device that constitute the door locking device, a door equipped with a locking device, and a booth equipped with the door equipped with the locking device. [Background technology]

[0002] Facilities used by an unspecified number of people are equipped with toilets. Each toilet booth is equipped with a lock, and the door can be locked to prevent it from being opened from the outside when in use (for example, Patent Document 1).

[0003] Some private rooms are equipped with a seat (e.g., Patent Document 2) for people with children (hereafter referred to as "guardians") to sit their children (infants aged 0 to 2.5 years) on while they relieve themselves, and private rooms equipped with such seats have the advantage that guardians can relieve themselves in peace by having their children sit on the seat. Even for children who do not sit on a seat (children aged 2.5 to elementary school age), they may be made to enter the private room with their guardians if it is unsafe to leave them waiting alone outside the private room for crime prevention reasons.

[0004] However, this type of seat is often installed near the door where the user can easily see it, and it can be accidentally unlocked while a child sitting in the seat is fiddling with the lock. Such accidental locks can also be made by children who are not sitting in the seat. To prevent such accidental unlocking, measures are taken, such as placing another lock higher than the original lock. [Prior art documents] [Patent documents]

[0068] (Door locking device operation) Next, the operation of the door lock device 60 of the present invention will be described. Here, the operation when restricting the sliding operation of the sliding body 22 and the operation when performing an emergency release in a state where the sliding operation of the sliding body 22 is restricted will be described.

[0069] 7(a) to 7(c), the sliding body 22 in the unlocked state is slid in the locking direction to lock it, and then the knob operation tool 52b of the operation part 52 is lowered. When the knob operation tool 52b is lowered, the fitting recess 51c of the locking part 51 covers the outside of the movable block 32, as shown in Figs. 8(a) and 8(b), and the rotation of the movable block 32, and therefore the rotation of the main body part 31 and the pinion shaft 22b interlocking with the movable block 32, is restricted, and the sliding operation of the sliding body 22 is restricted.

[0070] In this way, when performing an emergency release operation while the sliding operation of the slide lock 10 is restricted, as shown in Figures 9(a)-(c) and 10(a)(b), the emergency release jig X is inserted into the jig insertion hole 43b of the outer cover 43, and the push pin 33 in the push pin accommodating hole 31e is pushed toward the slide lock 10 with the emergency release jig X. When the push pin 33 is pushed with the emergency release jig X, the movable block 32 is pushed out to a position where it is disengaged from the fitting recess 51c of the engagement portion 51, as shown in Figures 11(a)(b), and the restriction by the restricting device 50 is released.

[0071] To release the restriction on the sliding body 22, the knob operation tool 52b of the operation portion 52 is pushed up, and the locking portion 51 is raised to a position where it does not interfere with the movable block 32. In this state, the restriction on the sliding operation of the sliding body 22 is released, so that the sliding body 22 can be freely slid in the unlocking direction and the locking direction.
