As shown in FIG. 4, the slider 12 has a tip 31a of a locking rod 31 when the crescent lock 14 is in the unlocked position.
An engaging portion 33 is provided for engaging.

In the illustrated case, the hooking portion 33 is formed by a notch, and when the movable piece 28 is located at the end of the long hole in the closing direction, the hooking rod 3
1's tip 31a engages with the engaging part 33, and the slider 1
The crescent lock 14 when the movable frame 2 is rotated in the closing direction with the crescent lock 14 kept in the unlocked state by preventing the bundle 25 from moving to the locked position. This is to prevent collision of the receiving metal fittings 34.

On the surface of the vertical rod 4 of the other opening/closing frame 3 that corresponds to the other opening/closing frame 2, there is a receiving metal fitting 3 at a position corresponding to each crescent lock.
4 is fixed and both opening/closing frames 2 and 3 are in the closed position, when the bundle 25 is rotated to the locked position, the crescent lock 1
4 is engaged with each receiving metal fitting 34.

The fixing of this opening/closing frame 3 to the outer frame 1 is shown in FIGS. 2 and 3.
As shown in the figure, lifting rods 41 are attached upward and downward from the center of the vertical rod 4, and a bundle 42 provided at the center of the vertical rod 4 is used to operate the approach and separation of both lifting rods 41. This is done by inserting a drop rod 43 fixed to a holder 44 of the outer frame 1.

At the center of the vertical rod 4 in the opening/closing frame 3, a movable piece 28 is provided with 45 abutments, with which the movable piece 28 comes into contact when the opening/closing frame 2 is placed in the closed position.

When the movable piece 28 comes into contact with this abutment 45 and moves inside the elongated hole 47 to the open end of the opening/closing frame 2, the end 31a of the latching rod 31 separates from the engaging part 33 as shown in FIG. Rotate to.

9 and 10 show the relationship between the movable piece 28 and the abutment 45, and FIG. 9 is a cross-sectional view corresponding to FIG. 4, and FIG. 10 is a cross-sectional view corresponding to FIG. 5.

As shown in FIG. 9, when the one side closing frame 2 is in the open position with respect to the other side opening/closing frame 3, the movable piece 28 is moved by the spring 29 in the closing rotation direction of the opening/closing frame 2 as indicated by the arrow A in the figure. Located in the front, the upper and lower retaining rods 31 and 31 engage with the engaging parts 33 and 33 of the upper and lower sliders 12.12 as shown in FIGS. 4 and 8, and the bundle 25 moves the upper and lower sliders 12.12. It is now impossible to do so.

In addition, as shown in FIG.
When the movable piece 28 comes into contact with the abutment 45 and stops immediately before the closed position, the opening/closing frame 2 compresses the spring 29 and rotates to the completely closed position.

In this way, when the movable piece 28 contacts the abutment 45 and the opening/closing frame 2 rotates to the fully closed position, the movable piece 28 moves against the opening/closing frame 2 as shown in FIG. Center box 1 toward the opening direction shown by arrow B in Figure 10.
By moving along the long hole 47 of 0, the upper and lower hanging pieces 31.31 have their tips 31a, 31a connected to the engaging parts 33
33 and slider 12. by bundle 25.

In addition, 46 in the figure is a lock attached to the vertical lever 4 of the opening/closing lever 2, and is engaged with the connecting lever 23 when the crescent lock 14 is in the locked position, so that the locked state can be locked.

The locking device of this invention has the above-mentioned structure, and its operation will be explained next.

When the bundle 25 moves the lock 14 to each Fresen 1 to the unlocked position and opens the opening/closing frame 2, the released movable piece 28 moves in the closing direction of the movable frame 2 due to the pressure of the spring 29. This movement causes the locking rod 31 to rotate, and as shown in FIG.
3 to prevent the bundle 25 from being operated to the locked position.

Therefore, there is no possibility that the opening/closing frame 2 is closed while the Talesen l-lock 14 is in the locked position in advance.

Furthermore, when the opening/closing frame 2 is placed in the closed position, the movable piece 28 in contact with the stop 45 moves to the opening side of the opening/closing frame 2, so the latch rod 31 releases its engagement with the slider 12 as shown in FIG. As a result, the bundle 25 can be operated in the direction of locking the crescent lock 14.

Although the embodiment has been described as a window, it may be a door, and the number of opening/closing frames may be one instead of two.

As mentioned above, according to this invention, the vertical rod of the opening/closing frame is
A plurality of vertical rods each having a cross-sectional shape with a longitudinal fissure provided on the end face, a hollow chamber provided inside the fissure, and a cover wall provided at one corner of the end face, and attached to the end face of the vertical rod. The crescent lock is interlocked with a connecting rod housed in a hollow chamber, and a bundle that rotates the crescent lock is attached to the surface of the vertical rod facing the opening/closing direction, so the crescent lock, slider, and connecting rod are flush against the opening/closing frame. As a result, assembly and repair can be easily performed, and since the vertical rod has a foot roller on the end face, each member is covered when the opening/closing frame is in the closed position, so the external shape of the opening/closing frame is neat. Finished,
This has the effect of making the design superior.

Also, since we operate multiple crescent locks in a bundle,
Easy to open and close, providing effective sealing.
