28A is fixed to the indoor side with screws 31 and the outdoor side member 25 is fixed.
It is composed of a wooden or resin indoor side member 25B to 28B that covers the indoor side of A to 28A. The sliding window is provided with a sublock as an auxiliary lock in addition to a crescent as a main lock. FIG. 3 is a cross-sectional view of the joining portion of the shoji screens 3 and 5. In the present embodiment, as shown in FIG. 3, a sublock 51 is attached to the lower rail 26 of the outdoor side shoji 5. In the sublock 51, the claw member 51A is rotated clockwise around the fulcrum pin 51B by a manual operation and protrudes indoors, and the tip 51C of the claw member 51A has the left vertical It faces the stopper 22S of the frame 22 with a gap S therebetween, and prevents the outdoor side shoji 5 from being opened. The stopper 22S is connected to a wooden or resin indoor member 22B of the left vertical frame 22 via a screw 32.
Fixed to. As shown in FIGS. 4A to 4D, the sublock 51 includes a resin case 51D and a case 51D.
D includes a claw member 51A supported via a metal fulcrum pin 51B, and a stopper 51E of the claw member 51A. FIG. 4 shows the surface of the claw member 51A.
As shown in FIG. B, a non-slip groove 51F is formed in the left half of the figure.
4A rotates clockwise (arrow X direction) about the fulcrum pin 51B as shown in FIG. 4D, and its tip 51C projects out of the case 51D. As shown in FIG. 3, the sub-lock 51 is a member for the indoor member 2 which constitutes the lower rail 26 of the outdoor sash 5.
6B, it is fixed to 26 A of outdoor members made of metal through the notch 61 of 6B. The outdoor member 26A is an extruded aluminum member as shown in FIGS. 5 and 6, and has a pair of fins 26F on the indoor surface, and a groove 26G is formed between the pair of fins 26F. ing. As shown in FIG. 6B, a part of the pair of fins 26F is cut out from the right end in the figure over a predetermined dimension L and a predetermined width W.
G, the case 51D of the sublock 51 is fitted from the right end in the drawing until it contacts the cutout end 26H of the fin 26F, and the groove 51G in the side wall of the case 51D (FIG. 4A, FIG.
The pair of fins 26F are fitted and fixed to C). The sub-lock 51 is formed by the groove 51G of the case 51D and the fin 2
6F, it is positioned in the direction of arrow Y in FIG. 6B, and by contact between case 51D and cutout end 26H of fin 26F, it is positioned in the direction of arrow X in FIG. 6B. After the case 51D is positioned, as shown in FIG. 5, a wooden or resin indoor member 26B is fixed to a metal outdoor member 26A by a fixture not shown.
