Is mounted so as to rotate horizontally, and a sliding door 24 is mounted at the lower end of the sliding door 5. Figure 2 when installing sliding door 5
As shown in FIG. 4D, the roller 23 is fitted into the upper rail 2 in a Kendon manner between the upper rail 2 and the lower rail 4, and the door pulley 24 is attached to the lower rail 4.
Placed on The sliding door 5 is provided with a handle 25,
The sliding door 5 can be closed or opened by holding the handle 25 and sliding the sliding door 5 in the longitudinal direction of the upper rail 2 or the lower rail 4.

An external sliding door device is constructed as described above. This sliding door device is provided with a locking means as follows. The lock device 7 is attached to the vertical frame 6a of the opening frame 6 with an attachment screw 26 such as a screw as shown in FIG. The lock device 7 is a flat rectangular parallelepiped housing 27.
The lock bar 9 is slidably mounted on the housing 27, and the lever 8 is provided integrally with the lock bar 9, and the lever 8 is exposed from the window 28 of the housing 27. By operating the lever 8, the lock bar 9 can be moved in and out in a direction perpendicular to the surface of the sliding door 5. A through hole 10 is formed in the sliding door 5 at a position corresponding to the position where the lock device 7 is attached, as shown in FIG. It is arranged as follows. The lock bar insertion fitting 11 is formed by recessing the lock hole 13, and is fitted into the through hole 10 on the back surface side of the sliding door 5. Through-hole cover plate 12
Is formed at the position of the through hole 10 on the front side of the sliding door 5, and the mounting boss 30 is inserted through the mounting hole 29. Then, screw-like mounting screws 31 are screwed into the mounting bosses 30 from the rear surface side of the sliding door 5 through the mounting holes 29, so that the through-hole cover plate 12 and the lock bar insertion metal fitting 11 are mounted on the front and back of the through-hole 10. is there.

By operating the lever 8 from the back side of the sliding door 5 with the sliding door 5 closed, the sliding door 5 can be locked and locked or unlocked. When the lever 8 is operated to cause the lock bar 9 to protrude, the tip of the lock bar 9 engages with the lock hole 13 and is locked. When the lever 8 is operated and the lock bar 9 is pulled, the lock bar 9 comes out. The door is unlocked and the sliding door 5 can be freely opened and closed. In this manner, even if the sliding door 5 is openable and closable externally, the locking means can be provided and locked, and the locking means can be provided with a relatively simple structure.

In a state where the sliding door 5 is closed and locked, it is necessary to provide a releasing means so that the lock can be released from the front side of the sliding door 5 in an emergency or the like. 14 is formed in the through-hole cover plate 12, and the release hole 14 is formed through the through-hole 10.
It is connected to 3. In the case of the lock hole 13 of the present embodiment, a communication hole 32 is formed in the bottom surface of the lock hole 13 as shown in FIG. Then, insert the tip of the lock bar 9 into the lock hole 1

The lock bar 9 is pressed so that the lock bar 9 comes out of the lock hole 13 to release the lock. By doing so, the lock can be easily released even from the front side of the sliding door 5.

In the above example, the lock device 7 is mounted so as to protrude from the outer surface of the vertical frame 6a of the opening frame 6.
As shown in FIG. That is, a recess 33 in which the lock device 7 is accommodated may be provided in the vertical frame 6a, the lock device 7 may be buried in the recess 33, and mounted with the mounting screw 26 such as a screw. In this case, the lock device 7 does not protrude to the outer surface side, so that the appearance is improved and the lock device 7 is not obstructed.

FIGS. 8 and 9 show another example. In the case of this example, a locking display means for displaying whether the sliding door 5 is locked or unlocked from the front side of the sliding door 5 is provided. Release hole 14 of through-hole cover plate 12
A display hole 34 is provided at a position below the display body 35. At the position of the display hole 34, a display body 35 is mounted on the inner surface side of the through-hole covering plate 12 so as to be slidable up and down. It is urged by a spring 36 to slide upward. The display body 35 is provided with a lock state display section 35a and a non-lock state display section 35b which display differently by color display or the like. A substantially L-shaped interlocking lever 37 is rotatably mounted on the inner surface side of the lock bar insertion metal fitting 11, and rotates in conjunction with the lock bar 9 when the lock bar 9 is inserted into the lock hole 13. It has become. An engaging portion 38 is provided on the display 35, and one end of an interlocking lever 37 is engaged with the upper surface of the engaging portion 38.

FIG. 8 shows the unlocked state, and
The lock bar 9 is not inserted into the lock lever 37, and the interlocking lever 37 is not pressed. Therefore, the display 35 is moved upward by a spring 36.
, The unlocked state display portion 35b of the display 35 and the display hole 34 correspond to each other, and the unlocked state is displayed. FIG. 9 is in the process of being locked, and the lock bar 9 is inserted and engaged with the lock hole 13. When the lock bar 9 is inserted into the lock hole 13, the interlocking lever 37 rotates, and by the rotation of the interlocking lever 37, the display body 35 slides downward against the spring 36, and the display body 35 slides downward. The lock state display portion 35a of the display 35 corresponds to the lock state display section 35a, and the lock state is displayed. With this configuration, it can be easily recognized from the front side of the sliding door 5 whether the door is locked or unlocked. In addition, since it is displayed in conjunction with the lock bar 9, it is accurately displayed with a simple structure.
