【Example】

 FIG. 1 is a schematic front view showing a state in which the handle lock of the present invention is attached to a window frame A ′, 1 is a handle seat, 2 is a handle, and 3 is a thumb turn. FIG. 2 is a front view showing a state in which the lock body 4 is attached to the handle seat. The lock body 4 is provided with an operation member 41 that slides up and down by rotation of the handle. The slider 5 that slides up and down together is fitted into the groove of the window frame A ′, and the lock pins 51 ... 51 formed at several positions of the slider 5 correspond to the lock pins 51 ... 51 of the window frame B. The window frame A'is locked, that is, the window is locked by engaging with the receiving metal fitting 6 attached to the location. Since the internal structure of the lock body 4 is known, its detailed description is omitted. 3 and 4 are a plan view and a side view, respectively, showing a state in which the handle seat 1 is attached only to the inside of the window frame A ', and the rotary shaft (square shaft) 21 of the handle 2 is the lock body. 4 and the operating member 41 of the lock body 4 slides up and down via the rotary shaft 21 by the rotation of the handle 2. 5 and 6 are a plan view and a side view showing a state in which the two handle seats 1 and 1 are attached to the inside and outside of the window frame A ′, respectively. A cylinder lock 7 is attached instead of the thumb turn 3, and a rotary shaft (square shaft) 71, which is attached to the plug of the cylinder lock 7 with 90 degrees of play, penetrates the case of the lock body 4 and a cam of the thumb turn described later. Is inserted into the fitting hole of the. 7 to 10 are a rear view and a vertical cross-sectional side view showing the internal structure of the handle seat 1 inside the window. The handle 2 is provided with a spring plate in the recess of the outer periphery of the cam 11 integrally fixed to the rotating shaft 21. When the projections of 12 and 12 are fitted, they are intermittently stopped within a rotation range of 90 degrees, and the thumb turn 3 has a fitting hole of a cam 13 pivotally supported at an upper position of the handle 2. A rotary shaft (square shaft) 31 that is detachably attached to the thumb turn 3 is fitted into the handlebar 13a to be attached to the handle seat 1. The cam 13 reciprocates in a click motion type within a range of 90 degrees by the action of the spring plate 14 in which the pin 13b integrated with the cam 13 is guided by the semi-circular groove of the back plate of the handle seat 1 by the rotation of the thumb turn 3. It is configured to rotate, and a locking piece 15 described later is configured to slide up and down by a pin 13b. The locking piece 15 is a plate-like member, and is inserted into the handle seat 1 so as to slide up and down while being guided by the mounting posts 1a, 1a of the handle seat, and is inserted in a portion through which the rotary shaft 21 of the handle 2 penetrates. The circular hole 15a having a diameter that allows the rotating shaft 21 to rotate without any trouble and the elongated hole 15b having a width substantially equal to the width of the rotating shaft 21 are continuously formed, and are formed in a portion corresponding to the upper cam 13. Is provided with an operation hole 15c having stepped portions a and b with which the pin 13b of the cam abuts. In the unlocked state of FIGS. 7 and 8, the locking piece 15 is in the raised position, and the rotary shaft 21 of the handle 2 is in a state of penetrating the portion of the round hole 15a. Therefore, the handle 2 should be operated. As a result, the rotary shaft 21 rotates without hindrance, the operation member 41 of the lock body 4 slides, the window frame is unlocked, and the window A can be opened. That is, when the locking piece 15 is in the raised position, the window can be freely opened and closed by operating the handle. Then, when the thumb turn 3 is gripped and rotated 90 degrees in the closed state of the window, the pin 13b integral with the cam 13 pushes down the lower step portion b of the operation hole 15c, and the locking piece 15 descends, as shown in FIG. Since the long hole 15b is fitted to the rotary shaft 21 as described above, the rotary shaft 21 is locked and the locked state is achieved. When the thumb turn 3 is rotated in the opposite direction to the above, the pin 13b of the cam pushes up the upper step portion a of the operation hole 15c to return the locking piece 15 to the state of FIG. 7, so that the rotation shaft 21 is unlocked. The handle can be operated. Next, when it is desired to provide a handle on the outside of the window as well as to open and close the window from inside and outside of the window as shown in FIGS. The rotating shaft 71 of the cylinder lock 7 provided on the handle seat 1 mounted on the outside is fitted into the fitting hole 13a of the cam 13 which penetrates the lock body 4 and is opposed, and the tip is slightly above the handle seat surface. Then, the thumb turn 3 from which the rotating shaft 31 has been extracted in advance is fitted to this portion, and the mounting is completed. By doing so, the rotary shaft 71 becomes the common rotary shaft of the cylinder lock 7 and the thumb turn 3, and the thumb turn 3 is operated from the inside of the window and the cylinder lock 7 is operated from the outside of the window. The rotary shaft 21 is locked to lock the rotary shaft 21 if possible.
