  However, as described above, the locking and locking mechanism can lock and unlock the opening door with a simple operation. However, for example, the locking and unlocking operation used for a rotary door provided in a toilet is not easy. When the mother and the child use the toilet together, there is a problem that the infant unintentionally rotates the lock lever 2 to unlock the door and opens the toilet door 4. Therefore, conventionally, in the toilet, another one is attached at a height position that is not reachable by the infant, but this has a problem that the cost becomes high.

Accordingly, in the invention described in claim 1, for example, as shown in the embodiment shown below, the lock base R is fixed to the lever base B fixed to the inside of the rotary door D or the door frame f, and the door frame f. The locking lever R is connected to a locking position that locks the opening / closing of the door across the door or a unlocking position that allows the opening / closing to rotate freely around the pivot 15 and is operated and locked from the inside of the door. Is provided with a lock means for restricting rotation toward the unlock position when the lock means is in the lock position, and when the lock means restricts the rotation of the lock lever R during an emergency release, The structure is characterized in that an external operation member is operated to release the rotation restriction of the lock lever R by the lock means.

  According to a second aspect of the present invention, in the hook lock according to the first aspect, the lock means rotates in conjunction with the lock lever R or the lock lever R, for example, as shown in the embodiment shown below. It is a rotation restricting member that restricts the rotating body that rotates toward the unlocking position.

  According to a third aspect of the present invention, in the lock according to the first or second aspect, for example, as in the illustrated embodiment shown below, the rotation restricting member is a rotation provided in a rotation track of the lock lever R. A slider lock S that slides between a restriction position and a restriction release position provided outside the rotation track is provided. When the lock lever R is in the lock position, the slider lock S is operated from the inside of the door to control the rotation. It is configured to be slidable to a position.

According to a fourth aspect of the present invention, in the hooking lock according to the first, second, or third aspect, the first operation hole 55a through which the external operation member is passed is formed outside the door, for example, as shown in the following embodiments. A first emergency operation portion 55 that opens toward the door and rotates the lock lever R to the unlocked position by the operation of the outer operation member through the first operation hole 55a from the outside of the door at the time of emergency release. A restriction release operation part 65a provided with an operation path L that penetrates the locking means through the clearance r between the opening door D and the door frame f through which the unlocking mechanism M and the external operation member pass is provided. When the means restricts the rotation of the lock lever R, the second emergency solution for releasing the restriction of the lock lever R by the lock means by the operation of the external operation member through the operation path L from the outside of the door. With mechanism N It is characterized in.

  According to the present invention, for example, when a mother and a child enter together and use the toilet, if the opening door is rotated and closed, the lock lever that is now in the unlocking position is rotated in the locking direction from the inside of the opening door. , Lock the door open and close once across the door frame. Next, the slide lock is slid from the rotation restriction release position that is now outside the rotation track of the lock lever to the rotation restriction position that is inside the rotation track, and the lock lever is restricted from rotating toward the rotation restriction release position. Double-lock the opening and closing. Accordingly, since the lock lever itself that restricts the opening and closing of the door is thus locked to double the opening and closing of the door by restricting the rotation of the lock lever toward the rotation restriction release position, the door can be easily operated even by an infant. When using the toilet together with the mother and child, the door can be prevented from being opened easily by unintentionally turning the lock lever without permission. . Therefore, it is not necessary to attach another door to the height position where the hand of the infant cannot reach, and it is possible to prevent the cost from increasing.

  In addition, according to the present invention, it is assumed that the lock lever is in a rotation restricted state by the locking means when it is necessary to make an emergency solution from the outside, such as when the user falls down on the toilet room side of the locked open door D In addition, the external operation member is inserted into the second operation hole through the operation path from the gap between the opening door and the door frame, and the lock means is slid to the rotation restriction release position by pressing the tip to rotate the lock lever. After releasing the restriction, from the outside of the same door, this time, the external operation member is inserted into the first operation hole of the emergency solution operation unit and rotated, and the first emergency solution mechanism is operated and connected to the emergency solution operation unit. If the lock lever is rotated to the unlocking position via the pivot, the opening door can be unlocked easily and reliably.

Concave. The guide groove 20 is linearly formed with the fitting hole 16 in between, and the slide lock S is applied so that the movement is stepped in accordance with the distance range of movement between the rotation restriction position and the rotation restriction release position. The shoulder portions 20a and 20b are provided on both sides in the length direction.

  The slide lock S includes a resin lock piece 25 and a steel slide plate 30. The lock piece 25 is provided with an attachment portion 25a and an engagement portion 25b having a U-shaped cross section that projects from the attachment portion 25a at a right angle. The slide plate 30 is provided with a guide hole 35 formed of an elongated hole with which the circumferential rib 16a of the lever base B engages in accordance with the distance range in which the lock lever R moves between the rotation restriction position and the rotation restriction release position. Corresponding to the shoulder portions 20a and 20b in the guide groove 20 of the lever base B, symmetrical shoulder portions 30a and 30b are formed on both side edges. The slide lock S is assembled in an L shape by attaching the base end of the slide plate 30 to the attachment portion 25a of the lock piece 25.

  The display panel C has a disk shape, and a cylindrical bearing portion 40 having an operation hole 39 made of a non-rotating square hole in the center of one surface in accordance with the cross-sectional shape of the pivot 15 is provided in a projecting manner. A pair of studs 45, 45 each having a female screw hole screwed to the shaft center are provided upright at a point-symmetrical position about the shaft center.
