An outer frame is constituted by the upper frame 14, the lower frame 4, and the side frames 15, and a blind 3 is installed between the side frames 15 on both sides below the upper frame 14. On one side of the opening composed of the side frame 15, the lower frame 4, and the blind 3, the door 2 as the child door is attached with a hinge 16 so that it can be opened and closed freely, and on the other side of the opening, the main door 17 is attached with a hinge. It is attached at 16 so that it can be opened and closed. When door 2 is closed, the second
As shown in the figure, it is stopped when it hits the door stop 6,
The rod 5 of the upper French drop 1 is projected to lock the rod 5 in the recess 3a of the blind 3, and the rod 5 of the lower French drop 1 is projected and the rod 5 is locked in the recess of the lower frame 4. Door 2 is locked by this. In Figure 2, side A is outdoors and side B is indoors. However, as shown in FIG. 2, even if the impact force F is strong, it is received by the locking piece 8a of the reinforcing metal fitting 8 on the surface of the outdoor side, and the door 2
will not be damaged. In the case of this embodiment, the reinforcing metal fitting 8 is U-shaped, so even if an impact force is applied to the indoor side while the outdoor side is visible, the door 2 is reinforced together with the door stop 6 and the door 2 is not damaged.

Further, FIGS. 3 and 4 show other embodiments described above. In this embodiment, the reinforcing metal fitting 8 is formed into an L-shaped plate shape, and is provided with a locking piece 8a at one end, as well as a mounting hole 13 and a fixing hole 19. The reinforcing metal fitting 8 is fitted into the cut groove 18 so as to lock the locking piece 8a to the surface of the door 2 opposite to the surface that contacts the doorstop 6,
It is fixed with a mounting screw 14 that can be inserted into a fixing hole 19 together with the French drop 1. A U-shaped notch 20 is provided in the flat plate portion 5a of the rod 5 of the French drop 1, and the operating portion 10 connected below the notch 20 is slidably inserted into the long hole 21 of the vertical piece 9b. . A push button 22 is installed above the elongated hole 21, and a cam portion 23 is provided on the back side of the push button 22. When the push button 22 is protruded from the surface by a spring 29, the cam portion 23 is The rod 5 is locked to the upper end of the notch 20 and does not move upward, and when the push button 22 is pressed, the cam portion moves backward and the push button 22 and the cam portion 23 are pressed.
