Description

[Detailed description of the invention] The present invention relates to a locking device for a sash, and particularly for sliding windows where the shoji are flush when closed, by operating the tightening handle of one shoji, the other shoji can be locked. It relates to a locking structure that triggers an unlocking operation.

In a sliding shoji consisting of shoji 1 and 2 as shown in Fig. 1, the shoji 1 and 2 are placed flush when closed, and in order to open it, the shoji 1 and 2 are placed flush as shown in Fig. 2 A.
We have previously proposed a satsui system in which the paper is pulled out to the indoor side and placed in a sliding state as shown in Figure 2 (b).

In the present invention, when closing this type of sash, locking can be performed with one touch using the tightening handle 3 of the shoji 1.

To explain the embodiment using drawings, FIG. 3 is a conceptual diagram for explaining its structure in an easy-to-understand manner. When the tightening handle 3 is rotated downward by 90 degrees, the matching sliders 4, 4 of the shoji 1 are moved in opposite directions. The distal end portions of the locking pieces 5, 5 attached to the distal ends of the locking pieces 5, 5 slide into the holes in the upper and lower frames to assume a locked state. Also,
The locking pieces 5, 5 have corner sliders 6, 6, and the vertical sliding of the above-mentioned matching sliders 4, 4 is controlled by corner sliders 6, 6.
The direction is changed by 90 degrees and the lateral movement is transmitted to the upper and lower stile sliders 7, 7, and the tips of the locking pieces 8, 8 attached to the tips of the stile sliders 7, 7 are pushed into the holes provided in the vertical frame. . In this way, the shoji 1 is locked at the four corners.

Specifically, as shown in FIG. 4, the movement of the above-mentioned matching sliders 4, 4 is caused by the rotation of the tightening handle 3 due to the engagement between the gear 9, which rotates as the tightening handle 3 is operated, and the racks 10, 10. is transmitted as linear motion.

As shown in an enlarged view in FIG. 5, a U-shaped locking piece 11 is provided on the shoji 1 side of the locking pieces 5, 5 as a transmission locking member, and a U-shaped locking piece 11 is provided on the shoji 2 side opposite to this. A protruding locking piece 12 is provided on the stopper 5', and when the shoji 1 moves in parallel to a position flush with the shoji 2 during closing, the protruding locking piece 12 is attached to the side of the U-shaped locking piece 11. It is fitted inside the U-shaped locking piece 11 from the open part.

FIG. 6 is a perspective view showing the fitted state.

Therefore, as described above, when the tightening handle 3 is rotated in the locking direction, the U-shaped locking piece 11 and the protruding locking piece 12 in the fitted state become integrated, and the locking piece 5
The moving movement is also transmitted to the locking piece 5'.

The locking pieces 5', 5' have corner sliders 6',
6' are connected to the locking pieces 8', 8' through the frame sliders 7', 7', and the movement of the locking pieces 5', 5' is converted into horizontal movement, and the locking pieces 8' , 8' are inserted into the holes provided in the vertical frame.

By installing a transmission locking member consisting of such a U-shaped locking piece 11 and a protruding locking piece 12,
Only by rotating the tightening handle 3 attached to the shoji 1 side, the shoji 1 and the shoji 2 can be brought into a flush state and locked at the same time.

FIG. 7 shows another transmission locking member that transmits the moving movement to the locking pieces 5', 5' on the shoji 2 side, and this shows when the tightening handle 3 of the shoji 1 is in the unlocked state. When locked, the semicircular pinion gear engages and rotates approximately 90 degrees.

In FIG. 7, a semicircular pinion gear is mounted coaxially with the gear 9 that rotates for the operation of the tightening handle 3, and is rotated together. On the other hand, on the shoji 2 side, there are similarly provided a gear 9', racks 10', 10', and a semicircular pinion gear 1' in rack and pinion engagement.
10' is connected to locking pieces 5', 5' by matching sliders 4', 4'.

Now, when the handle 3 is rotated 90 degrees in the locking direction, the pinion gear eye, which is not in a meshing relationship when the lock is unlocked, comes into a meshing relationship with the pinion gear eye' on the shoji 2 side, almost synchronizing with the sliding of the sliders 4 and 4'. The sliders 4', 4' slide in the same direction. That is, the movement is transmitted to the locking pieces 5, 5' on the shoji 2 side. This is transmitted to a movement in which the tips of the locking pieces 8', 8' are pushed into the holes provided in the vertical frame.

Therefore, the lock can be easily locked, and since only one locking handle is required, it is aesthetically superior.
