According to the first embodiment, since the door 1 can be locked and unlocked by sliding the operation unit 9 in the vertical direction, the operability is better than the operation of turning the knob as in the prior art.
Since the urging member 21 urges the latch 19 in the collapsed state, if the operating portion 9 is damaged or falls off due to the door being closed forcefully, the latch 19 exerts the urging force of the urging member 21. Since it receives and is located in a sinking position and is in an unlocked state, it can be prevented from being trapped in the bathroom when the operation unit 9 is damaged or the like.
Since the pressing portion 35 presses the inclined portion 33 by sliding the operating portion 9 to the upper position and the latch 19 protrudes, the position of the pressing portion 35 when the operating portion 9 is in the lower position is Since operation is possible within the range of the inclined portion 33, it is difficult to be affected by processing errors and mounting errors.
Since the operation unit 9 has the upper position as the locking position and the lower position as the unlocking position, as shown in FIG. 5, the operation unit 9 is provided at a height H that is difficult for children to reach. Since the operation requires an operation to a higher position, it is possible to prevent the child from operating incorrectly.

As shown in FIG. 1, the inclined portion 33 has a vertical flat surface 33 c that is continuous with the lower inclined surface 33 a, and the flat surface 33 c presses the latch 19 when the operating portion 9 is in the upper position. Since it is located in the state which carried out, it is easy to hold | maintain a locking position because the press part 35 of the operation part 9 is located in the flat surface 33c.
Furthermore, in this embodiment, since the flat surface 35b of the pressing portion 35 contacts at a position where the pressing portion 35 contacts the flat surface 33c of the inclined portion 33, the inclined surface 33 and the pressing portion 35 are flat surfaces. Since the two come into contact with each other, the locking position can be stably maintained.
Since the pressing portion 35 presses the lower inclined surface 33a of the inclined portion 33 with the circular arc surface 35a, the pressing portion 35 can smoothly come into contact with the inclined surface.
As shown in FIG. 2 (c) and FIG. 4, the locking part 13 is inserted and attached to the expected opening 23 formed on the prospective surface of the door toe 5a, and is formed on the finding surface of the door toe 5a. Since the operating portion 9 is attached by inserting the pressing portion 35 from the finding opening 25, the operation is performed with a simple structure that attaches to the opening 23, 25 formed on the finding surface and the prospective surface of the door toe 5a. A latching structure of the latch 19 can be formed by operating the portion 9 up and down.
Since the operation portions 9 and 9 are provided on the indoor side and the outdoor side of the door 5 and the male and female are coupled by the projection 37 and the recess 39, the operation portions 9 and 9 can be easily coupled. It is easy to prepare various designs for the knob 36 of the section 9 and to select and install various designs.
The latch 19 is provided with a lower inclined surface 33a and an upper inclined surface 33b in the inclined portion 33 and is formed symmetrically with respect to the line BB shown in FIG. 2B. The same type of door can be used for left doors (left-hand doors) and right doors (right-hand doors).
As shown in FIG. 4, a protrusion 26 is provided on the case portion 17 b of the pedestal 17, and a recess 24 corresponding to the protrusion 26 is provided in the expected opening 23 of the door rod 5 a to which the pedestal 17 is attached. It is possible to prevent erroneous mounting that is reversed. That is, in this embodiment, since the latch body 31 is substantially U-shaped when viewed from the door end, the shape that can be seen on the side of the bathroom and the side of the dressing room is different, but the pedestal 17 is mounted horizontally reversed. By preventing this, the shape seen from the dressing room side and the bathroom side can be made the same.

The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the present invention.
The operation unit 9 is not limited to being provided on both the undressing room side and the bathroom side, but may be at least on the undressing room side.
The upper side of the pressing portion 35 is not limited to an arc surface, and may be a surface having a corner.
Regardless of the bathroom door, the door 1 according to the present invention may be an entrance door or a door that partitions the room.
