【Example】

 In each of the illustrated embodiments, 1 is an inner door, 2 is its sill rail, 3 is an outer door, 4 is its sill rail, 11 is a body of a locking device, 21 is a locking rod, and 22 is a locking rod in the outdoor direction. A main body 11 is a molded product made of plastic, aluminum or the like, which is a spring for urging the elastic body. The main body 11 is fitted in the rail 2 so that the main body 11 can slide along the rail 2 and the groove 12 opened on the lower surface and the lock. In order to movably support the rod 21, there is provided a support hole 13 provided in an upper portion in a direction orthogonal to the groove 12.

The main body 11 is composed of an upper main body A having a supporting hole 13 and a lower main body B having a groove 12, and the lower surface of the upper main body A and the upper surface of the lower main body B have a T-shaped or dovetail-shaped cross section. It has a sliding engagement device 14 consisting of a ridge and a groove. This is because the distance between the inner door rail 2 and the inner surface of the lower horizontal frame 5 of the outer door cannot be fixed depending on the sash maker, the size of the window frame, etc. The upper body A 1 can be slid in the indoor direction or the outdoor direction with respect to the main body B so that the surface a of the upper body A facing the outdoor can be brought close to the indoor surface of the lower horizontal frame 5 of the outer door. For this purpose, the upper end of the screw 15 passed through the lower body from below is screwed into the upper body and tightened to fix it in the adjusted position. For this reason, holes 15 'into which the upper ends of the screws 15 are screwed are provided in the upper body in the same direction as the support holes 13 at predetermined intervals.

The support hole 13 in the embodiment of FIGS. 1 and 2 is a stepped cylindrical through hole having a large diameter portion 16a on the outdoor side and a small diameter portion 16b on the indoor side concentrically, and the locking rod 21 is It comprises a plug 23 guided on the inner circumference of the large diameter portion 16a, a shaft 24 guided through the small diameter portion 16b, and a knob 25 provided on the outer end of the shaft 24. The knob 25 and the knob 25 are integrally formed, and the inner end of the shaft 24 is fixed to the separately formed plug 23 by screwing. Then, a coil spring 22 is provided between the step 16 of the through hole and the inner surface of the plug 15, and the shaft 24 inserted from the small diameter portion 16b is passed through the coil spring 22 and the inner end thereof is fixed to the plug 15. The lock rod 21 is assembled with and the stopper 23 is elastically pressed by the spring 22 in the outdoor direction, so that the tip end of the stopper 23, that is, the tip end of the lock rod 21 is projected outward from the surface a of the upper body facing the outside. At this time, since the knob 25 comes into contact with the inner surface of the main body, the locking rod 21 does not come out from the support hole 22 only by protruding the front end portion from the surface a of the main body by a certain amount.

In the embodiment shown in FIGS. 3 and 4, the support hole 13 is a blind cylindrical hole that is closed in the room direction, and its depth length is sufficiently longer than the locking rod 21. The upper main body A has a slit 17 on the upper surface or the side surface that communicates with the supporting hole 13. The locking rod 21 has a plug 26 that is partially inserted into the support hole 13 and is slidable, and a knob 27 that is attached at a right angle to the plug 26 by screwing or the like and a part of which protrudes from the slit 17 to the outside. Become. The coil spring 22 is inserted into the support hole 13 in front of the plug 25, and then the second half of the plug 25 is pushed into the support hole while compressing the spring 22, and the tip of the knob 27 inserted from the slit 17 is inserted into the rear end of the plug 25. Install on. As a result, the spring 22 pushes the stopper 25 out of the support hole until the knob 27 contacts the front end of the slit 17, and the tip of the stopper 25, that is, the tip 21 'of the locking rod 21 faces the outside of the upper body. It projects outward from the surface a. The slit 17 is L-shaped having a lateral portion 17 'at its rear end, and when the knob 27 is pulled back against the spring 22 and put into the lateral portion 17', the tip of the stopper 25 is pulled into the support hole 22.

For use, a hole 6 into which a front end portion 21 ′ of a locking rod projects is formed in a lower horizontal frame 5 of an outer door. In order to form a narrow gap for ventilation, etc., a hole 6 was made at a position separated by the size of the gap to be formed from the vertical frame 1a on the meeting side of the inner door, and it was mounted so as to straddle the rail of the inner door. Insert the tip of the locking rod of the main body into the hole. In order to straddle the main body on the rail 2, the groove 12 may be fitted into the rail 2 from above while pushing the locking rod 21 against the spring 22, but in the embodiment shown in FIGS. 3 and 4, the knob 26 is slit. It suffices to insert the groove 12 into the rail 17 from above and to retract the tip of the locking rod.

In this way, when the main body is attached to the rail 2 and the front end portion 21 ′ of the locking rod is put into the hole 6 in the lower horizontal frame of the outer door, the main body 11 is kept in contact with the vertical frame 1 a on the assembling side of the inner door. When the door is opened, a required gap 8 can be formed between the vertical frame 3b of the outer door and the corresponding vertical frame 7 of the window frame (see FIG. 5). On the contrary, the inner door is opened until the meeting side vertical frame 1a of the inner door comes into contact with the main body, and the inner frame is required between the vertical frame 1b of the door frame and the vertical frame 9 of the window frame facing the door frame. It is also possible to form the gap 8 (see FIG. 6). Of course, both the inner and outer doors are opened until the summing side vertical frame 1a of the inner door abuts the main body, and the door contact side vertical frames 1b and 3b of both doors and the both vertical frames 7 and 9 of the window frame. It is also possible to form gaps 8'and 8'having a required total width between them and (see FIG. 7).

In any of the above cases, when the assembling side vertical frame 1a of the inner door comes into contact with the main body, neither the inner door nor the sliding door can be opened any further. When opening one or both of the sliding doors more or closing the sliding doors, the knobs 25 and 27 may be pulled and the locking rod may be pulled out from the hole 6 for operation. Since the main body 11 is movable across the rails of the inner door, if the locking rod 21 is pulled out of the hole 6, the tip of the locking rod 21 is pushed by the spring 22 and is pushed against the lower lateral frame 5 of the outer door. However, when the inner door is opened, it is pushed by the inner door and moves along the rail 2, so there is no problem.

Further, when the hole 6 is opened at a position close to the summing-side vertical frame 1a of the inner door, the rail 2 is attached and the tip 21 'of the locking rod 21 is inserted into the hole 6, the main body of the inner door is When it is brought into contact with the summing side vertical frame 1a, the door is locked so that neither the inner door nor the outer door can be opened (see FIG. 8). To open the door, pull the knobs 25 and 27, pull out the locking rod from the hole 6 and operate.

In the embodiment shown in FIGS. 3 and 4, since the pulling knob 27 can be fastened to the lateral portion 17 ′ of the slit and the tip 21 ′ of the locking rod cannot be put in the hole 6, When the door is halfway opened or closed, the tip 21 'of the locking rod enters the hole 6, and each time the door is pulled, the tip 21' is pulled out from the hole 6. Disappears.
