A thin lid 6G is integrally formed on 6H' so that it can be opened, and if necessary, the drain channel 6F on the left side in the figure is connected to the side where water is drained (in this example, since the wall portion 23 is formed on the right side). It is formed so as to open the drainage channel 6F.

Prior to installing the mullion 5 formed in this way vertically, a drainage hole is placed on the front edge 3F of the lower frame 3 to form a drainage hole on the drainage side of the drainage piece 6 at the vertical installation position of the mullion 5, that is, at the intervening position of the drainage piece 6. A drain port 3J aligned with the drain port 6H of the channel 6F is penetrated, and the drain piece 6 is mounted on the mullion mounting portion 3G so that the drain port 6H is aligned with the drain port 3J.
The lower end side of the mullion 5 is inserted into the screw insertion hole 6C of the drainage piece 6 from the lower surface side of the mullion mounting part 3G, and is screwed into the screw receiver 5F. The upper end of the mullion 5 is screwed onto the upper surface of the mullion attachment part 2F of the upper frame 2 with a screw 7, so that the mullion is installed vertically. The bathroom is divided into two sections, and a bathroom sliding door 8 is installed in the same window frame.

Reference numeral 8 refers to the above-mentioned bathroom sliding door, which is assembled into a rectangular shape with an upper stile 9, a lower stile 10, and left and right stiles 11, and a horizontal stile 1 between the left and right stiles 11.
2 are hung horizontally, and the frame assembly is divided into upper and lower sections, and a panel 13 made of glass or synthetic resin is fitted into the divided sections, and an entrance is provided on the right side of the horizontal frame 12 near the vertical frame 11. A locking device 14 is attached which locks with the mullion 5 when the section 1A is closed.

This locking device 14 is a lid body 1 attached to the bathroom side.
5 and a box 16 attached to the indoor side, a lock case is formed, and an edge 17 formed on the box 16
A screw receiving portion 17B is formed on the left and right side edges 17A, and a lower edge 17C is formed on one side edge 17A.
A partition plate 17D is provided at a predetermined distance from the partition plate 17D, and a mounting portion 17E of the locking plate 18 is formed.

Reference numeral 18 denotes the above-mentioned locking plate, which is formed in a symmetrical shape approximately in the shape of a bell in the plan view, and has a rotating shaft 19 attached to the mounting base 18A side, and is symmetrically engaged at a predetermined angle to the rotating end side. A stop surface 18B is formed. Further, a protrusion 21 is provided on a portion of the center line of the upper surface of the locking plate 18 to protrude and connect with the operating rod 20 . Furthermore, the side plates 15A and 16A of the lid 15 and the case 16 have long groove holes 15B and 16B that are aligned with the mounting portion 17E and into which the locking plate 18 can be inserted.
is opened, and the locking plate 18 is rotatably attached to the mounting portion 17E via a rotation shaft 19, and an operating rod 21 is linked to the protrusion 20 thereof.

21 is the above-mentioned operating lever;
is formed into a block shape so as to be slidable in the direction of the arrow in the figure within the edge portion 17, and a convex portion 21A is provided on the lower surface of the edge portion 17 to slidably abut on the upper surface of the locking plate 18.
A locking plate 1 is formed on the lower surface of the convex portion 21A.
The locking plate 18 is fitted and guided by the protrusion 20 protruding from the locking plate 18.
A diagonally recessed groove 22 is formed in order to protrude toward the bathroom side or the changing room side, and a groove 22 is formed in the side plate 16A on the surface of the operating rod 21 opposite to the side plate 16A of the box 16. A pin 21B is formed to fit into the guide groove 16C, and a window 15C is formed in the side plate 15A of the lid 15, and a pin 21B is formed on the side plate 15A side of the operating rod 21 to be guided by the window 15C. A convex knob portion 21C is provided in a protruding manner. The operating rod 21 formed in this way has its groove 22 and projection 20 fitted, and the pin 2
1B is fitted into the guide groove 16C and is slidably housed within the edge 17. In this way, the locking plate 18
The box 16 containing the and operating rod 21 is inserted from the changing room side of the horizontal bar 12, and the lid body 15 is inserted from the bathroom side of the horizontal bar 12.
They are fitted into the mounting holes 12A opened in 2 and fixed with screws 25, and the operation part 1 is installed on the bathroom side.
4A is formed, and by operating the same knob 21C in the horizontal direction in the figure, the locking plate 18 is formed to be able to protrude toward the bathroom side and the changing room side. The locking surface 18B of the locking plate 18 is arranged opposite to the side edge 5C of the mullion 5 to be locked, and in this case, the surface 18C of the locking plate 18 on the dressing room side is connected to the side plate of the box 16. 16A, and when the locking plate 18 is protruded toward the changing room side, the bathroom side surface 1
8C is configured to be located substantially on the same surface as or inside the outer surface of the side plate 15A of the lid body 15.

The sash 1 with the bathroom sliding door 8 fitted with the locking device 14 installed in this way is attached to the entrance/exit opening W, and a wall portion 23 is formed on the bathroom side of the storage section 1B.

Next, the operation and effects of this embodiment configured as described above will be explained.

Now, the locking device 14 in this example is attached to the horizontal beam 12 of the bathroom sliding door 8 installed in the sliding door sash 1 in a single-swing manner, and is removably locked to the mullion 5 installed vertically on the sliding door sash 1. The locking device 14 has horizontal long groove holes 15 corresponding to the inner and outer plates 15A and 16A of the upper case consisting of the lid 15 and the box 16.
B, 16B are opened, and the lock case has long groove holes 15B, 16B inside and outside through the rotating shaft 19.
A locking plate 18 is provided so as to be horizontally rotatable to the side, and a protrusion 20 is provided protruding from the rotation end side of the locking plate 18. An operating rod 21 is provided so as to be slidable along the same, and the operating rod 21 is recessed with an oblique groove 22 that engages and guides the protrusion 20 of the locking plate 18. Therefore,
According to the locking device 14 of this embodiment, the locking plate 18 is provided so that it can be projected to either the bathroom side or the changing room side by operating the operating part 14A, so that the locking plate 18 can be protruded to either the bathroom side or the changing room side. As shown, the mullion mounting part 2F of the upper frame 2 faces indoors, and the dovetail grooves 4D provided in the partition pieces 4C of the left and right vertical frames 4 face the bathroom side as shown in the figure. Mounting part 2F3
Even when the mullion 5 is installed vertically between G and the mullion 5 is installed indoors, it can be locked. Therefore, it is convenient that the mullion can be locked regardless of whether it is installed vertically on the bathroom side or the changing room side.

In the above embodiment, the width of the locking plate 18 on the rotation end side, that is, the locking surface 18B side, is made larger than the width of the locking device 14. However, the width is not limited to this, and for example, as shown in FIG. The device 14 has a locking surface 26A on the rotating end side like the locking plate 26 shown in FIG.
It may also have a shape that fits inside. In this case, it is convenient to attach markings clearly indicating the positions a, b, and c of the protrusion 20 relative to the groove 22 on the window 15C on the operation section 14A side and on the operation rod 21.

The present invention is a locking device that is attached to the horizontal crosspiece of a bathroom sliding door to lock a locking plate in the mullion, and an operation part is provided on the bathroom side of the locking device to lock the locking plate on the bathroom side and the locking plate. Since it is connected so that it can protrude from either side of the changing room, it can be locked even if the mullion is installed vertically on either the bathroom side or the changing room side, so it can be used as a locking device for bathroom sliding door sashes. This is an extremely practical idea.
