An operation key 72 having a knob blade 75 at the upper end is prepared.

The operation of this mechanism will be explained next. Now, in order to open the closed shoji 8, first turn the indoor handle 43, lower the interlocking rod 45 to release the fastener, and in that state slide the shoji 8 along the rails 6 and 7. When the shoji 8 is opened to 30 degrees, the contact piece 25 of the slide rotation shaft block 15 hits the slide stopper 23 as shown in the fourth figure, and the lock pin 27 locks into the locking hole 29, so that the shoji 8 is held in that position. Stop and lock. In this state, the shoji 8 cannot be opened any further using the indoor handle 43 and the lock release knob 31, thereby preventing personal injury from falling through the window.

In this state, if the worker wants to open the shoji 8 by 90 degrees or more in order to clean the outside surface of the glass 13, he or she borrows the stop release operation key 72 kept by the administrator and presses it on the support tube 65. Insert the push pin 68 inside and push down the push pin 68, which swings the release lever 32 at the tip of the push pin 68, and the tip of the lever 32 releases the slide stopper 23.
Press down, then press edge 7 of the operation keys 72 above.
4 in the groove of the push pin head 69 and turn it slightly to lock the guide pin 70 in the locking groove 67 and maintain the pressed down state, and then turn the lock release operation knob 31 of the slide lock mechanism. Pull it upward to disengage the lock pin 27 from the locking hole 29, and in this state, slide the shoji 8 to open it widely.
The slide stopper 23 above slides over the door roller 2.

Slide stopper 2 by inclined rear end 77 of 0
3 is automatically pushed down and returns to the original 30 degree open position, the lock pin 27 automatically locks into the locking hole 29 and returns to the locked state. Therefore, the operation key 72
Turn the guide pin 7 of the push pin 68 slightly in the opposite direction.
0 is released from the locking groove 67, and as a result, the operation key 72 is pushed upward by the spring 71 together with the push pin 68, and escapes from the support tube 65. The escaped operation key 72 is kept by the administrator.

In this embodiment, to explain the case where the shoji is opened widely from the outside in the event of a fire or the like, when the shoji 8 is closed, the clutch opening/closing operation pin 56 is first pushed to open the driven piece 54.
is moved to the driven position, and at this time the stop ball 5 is moved to the driven position.
9 is locked in the adjacent locking groove 58 and the driven piece 54
hold in that position. Next, when the outdoor handle 44 is turned to lower the interlocking rod 45, the fastener is released and the driving piece 50 is lowered and its pressing protrusion 52 pushes down the driven piece 54, thereby causing the entire sliding plate 47 to move downward. descends and pulls the wire 37, swinging the release lever 32 connected to the wire to the releaseable position, and the sliding plate 38 on the side of the vertical stile 12 connected to the wire 37.
The driven pin 40 is raised and engaged with the sliding plate.
Next, the lock pin 27 is appropriately pulled up from the surface of the rail 7 via the knob 31 and the rods 30 and 26, and in this state, the shoji 8 is slid in the opening direction.
At the position of the slide stopper 23, the release lever 32 first pushes down the slide stopper 23 to allow the following door wheels 21, 21 to pass, and the lock pin 27 also passes through the locking hole 29 while remaining in the raised position.
As a result, the shoji 8 reaches the desired open state.

After the shoji is closed after handling the accident, when the clutch operation pin 56 is pulled back outward, the driven piece 54 is automatically returned to the undriven position by the spring 55.

Note that, of course, for windows that do not need to be opened on the outdoor side, the outdoor side operating handle 44 and the like are unnecessary.

Instead of the stop release operation key 72, a conventional screwdriver or other various operation members can be used.

Further, although the release operation key 72 in the above example is configured to act indirectly on the release lever 32 via the push pin 68, there is also a structure in which the release operation key 72 is configured to directly act on the release lever 32 without using the push pin. It can be designed according to the example.

(Effect of the invention) According to the sliding open window opening regulation mechanism of the present invention, by removing the release operation member for releasing the stoppage of the slide stopper from the shoji and storing it separately, the shoji can be stopped by the slide stopper. Although the shoji can be opened to the narrow angle required, allowing the necessary ventilation, it is also possible to leave the shoji in a state where it is impossible to open it any further from the indoor side, thereby reducing the risk of personal injury from the window. On the other hand, if you want to open the shoji 90 degrees or more to clean the outside side of the shoji glass, you can stop the slide stopper from the inside using the stop release operation member mentioned above. This allows the shoji to be opened freely, making it extremely convenient to use.
