Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a locking device for a sliding door that locks and locks a sliding door running on a protruding rail provided within a sash frame.

[Prior art and problems to be solved] In conventional sliding door locking devices, when locking only one sliding door, a sickle lock is provided on the sliding door side and a lock receiver is provided on the vertical frame side. I was doing it.

In this way, conventional methods have the drawback that the lock receiver is provided on the vertical frame, which requires a large amount of work to form the lock receiver.Furthermore, when the sliding door is opened, the lock receiver is exposed to the outside and the appearance is affected. This had the disadvantage that it made the person's appearance look bad.

[Means for solving problems] The present invention has been made in view of the above points, and is a device that releasably locks a sliding door that runs on a protrusion rail provided in a sash frame, and is designed to releasably lock a sliding door that runs on a protrusion rail provided in a sash frame. A sweeping part is provided near the frame by arbitrarily separating the end of the protruding rail provided on the lower frame from the vertical frame,
The sweep-out portion has a flat floor surface, and a locking member that protrudes downward and retracts from the vertical stile on the door stop side of the sliding door and locks to the end of the protruding rail in the sweep-out portion. The present invention proposes a sliding door locking device that eliminates all of the above-mentioned conventional drawbacks by providing a locking device.

[Examples] Examples of the present invention shown in the drawings will be described in detail below. Fig. 1 is a front view of the present invention in use, Fig. 2 is a sectional view along AA of Fig. 1, Fig. 3 is a perspective view of Fig. 2,
FIG. 4 is a longitudinal sectional view of the main part.

In each of the above figures, the present embodiment releasably locks the sliding door 10 running on a protruding rail 23 provided in the sash frame 20, and has a sweep-out portion at a portion of the lower frame 21 near the vertical frame 22. 24, and a locking tool 1 that locks onto the end 23a of the protruding rail 23 is provided on the vertical stile 11 of the sliding door 10.

The protruding rail 23 is laid on the upper surface of the lower frame 21, and its end 23a is separated from the inner surface of the vertical frame 23 by an arbitrary distance, and a sweep portion 24 is provided at the upper end of the lower frame 21. It becomes like forming. The sweep-out section 24 is normally used to sweep out dirt accumulated on the upper surface of the lower frame 21 to the outside.

According to the embodiment, the protrusion rail 23 is
The lower frame 21 is firmly attached by locking its lower edge into a vertical groove 25 formed in the longitudinal direction of the upper surface. In addition, the vertical groove 25 and the protrusion rail 2 in the sweeping part 24
A rail cover 26 is attached to the end portion 23a of the rail 3 to flatten the floor surface of the sweeping portion 24 and close the hollow portion of the rail end portion 23a. Therefore, the rail end portion 23a in the embodiment
is substantially constituted by the upper part of the rail cover 26.

Next, the locking tool 1 is attached to the vertical stile 1 on the doorstop side of the sliding door 10.
1, and in the embodiment, it is composed of a bar punch of a predetermined length, and the lower end 1a of the bar punch protrudes and retracts downward from the lower surface of the vertical stile 11, and the end of the protrusion rail 23 It is adapted to be locked to the portion 23a.

As shown in FIGS. 2 and 3, the lower end 1a of the locking tool 1 has one side curved so that it can be smoothly locked to and removed from the end 23a of the protruding rail 23. It is set as.

The locking tool 1 is vertically movably supported by a support part in the vertical stile 11, and a handle 2 provided in the center is placed in a vertically long guide groove 4 formed on the surface of the vertical stile 11. They are movably engaged. However, the locking tool 1 is moved up and down by the length of the guide groove 4 via the handle 2 which projects outward from the guide groove 4.

A locking part 5 is provided at the upper end of the guide groove 4, and the locking tool 1 is rotated at an arbitrary angle to engage the handle 2 in the locking part 5, so that the locking tool 1 is placed in the upper position. By supporting the locking tool 1 on the rail end portion 23a, the locking tool 1 is kept unlatched to the rail end portion 23a. Further, the retaining tool 1 can be freely held in the upper position by, for example, constantly pressing the retaining tool 1 into the vertical stile 11 using a leaf spring.

A door roller 13 is provided on the lower stile 12 of the sliding door 10, and the sliding door 10 runs on a protrusion rail 23 via the door roller 13.
2, that is, when the window opening 30 is closed, when the locking tool 1 is made to protrude from the vertical stile 11 to the sweeping part 24 of the lower frame 21, its lower end 1a will engage with the rail end 23a. Then, the sliding door 10 is locked.

Next, in other embodiments shown in FIGS. 5 and 6,
Two locking devices 1, upper and lower, are provided, and the corresponding ends of the locking devices 1, 1 are connected to each other via a linking portion 6 consisting of a rack and pinion at approximately the middle of the vertical stile 11. There is. This linking part 6 is housed in a support part 3 provided within the vertical stile 11, and
It is connected to a handle 2 provided on the outside of the vertical stile 11. By rotating the handle 2, the two locking tools 1, 1 are moved up and down in different directions via the linking portion 6.

By rotating the handle 2, the lower end 1a of the lower locking tool 1 locks with the rail end 23a of the sweeping part 24, as in the first embodiment, and the upper locking tool Reference numeral 1 is for locking with a receiver 7 provided on the lower surface of the upper frame, and the double locking provides a stronger lock.

[Effects of the invention] As described above, the present invention provides a sweeping part in the lower frame provided with the protruding rail, and also provides a locking tool that appears and retracts from the bottom of the vertical stile on the vertical stile, and the locking tool is installed in the vertical stile. Since the sweeping part is configured to lock onto the end of the protruding rail, the sweeping part and the rail end also serve as a lock receptacle, thus eliminating the labor-intensive work of forming a lock receptacle. The effect is that it can be done.

In addition, the present invention has a structure in which the flat sweep part provided on the lower frame also serves as the lock catch, so when the sliding door is opened, it is possible to easily sweep out dirt using the flat surface, and the lock catch part, etc. It has the effect of preventing trash from accumulating.
