[0007]

[Action]

 When one of the desired left and right operation members is lowered, the slider is guided by the lock case via the movable piece and descends as it is. Then, the hook rotates around the first movable shaft or fixed shaft supported by the lock case by the second movable shaft or movable shaft that descends together with the slider while the tip moves out of the front opening. .

Therefore, when the hook rotates due to the lowering of the slider, in the case of the embodiment in which the first movable shaft pivotally supporting the hook engages with the oblique guide notch of the slider, the slider lowers. As a result, the first movable shaft goes into the back of the guide notch. Then, the first movable shaft moves slightly into the horizontal slot of the lock case, while the second movable shaft moves slightly into the guide slot of the slider toward the inside or inside of the frame, and as a result, engages with the hook. The outer sill that pulls is attracted. In the case of the embodiment in which the fixed shaft pivotally supporting the hook engages with the guide notch in the vertical direction of the slider, even if the hook rotates to the locked state, the outer frame is not drawn to the inner frame.

As it descends, the first movable shaft 31 goes into the depth of the guide notch 16. Then, the first movable shaft 31 moves to the horizontal elongated hole 8 of the lock case 7, while the second movable shaft 32 moves to the guide elongated hole 18 of the slider 12 to the indoor side or the inner frame to some extent. As a result, the outer frame 2 having a hook receiver that engages the hook 30 is drawn in close contact. By the way, when the slider 12 descends and the sickle lock is locked, the lower end of the stopper 34 abuts the receiving pin 35, and as a result, the movement of the second movable shaft 32 and the slider 12 is restricted. 30 does not rotate in the unlocking direction.

It should be noted that when the manipulator 24 is raised upward, an operation mode opposite to that described above is achieved, and the cam 30 moves the first movable shaft 31 with the second movable shaft 32 that moves up together with the slider 12. It rotates in the unlocking direction as a fulcrum and enters the inner frame 1.

[0028]

[Different Examples]

 Next, a different embodiment shown in FIGS. 10 and 11 will be described. In the description of this embodiment, the same parts as those of the embodiment of the present invention will be designated by the same or similar reference numerals and overlapping description will be omitted.

The second embodiment shown in FIGS. 10 and 11 is mainly different from the first embodiment in that the guide notch 16A of the slider 12A is formed in the vertical direction, and The first shaft of the hook 30A that engages with the cutout portion 16A is a fixed shaft 31A that is laterally suspended in a round shaft hole 8A formed in the lock case 7A. In this case, the second axis of the cam 30A is the same as the first embodiment in that it becomes the movable shaft 32A that moves up and down together with the slider 12A as in the first embodiment.

That is, in this embodiment, the lock case 7A fixedly incorporated in the inner frame 1 and having the shaft hole 8A, and the lock case 7A movably provided in the lock case 7A are provided. A slider 12A having a vertical guide notch 16A that engages with a fixed shaft 31A that is laid across the hole and an elongated hole 18A that supports a movable shaft 32A for a cam, and a slider 12A that is connected to the upper end of the slider 12A, and The left and right operation members 20 respectively attached to the left and right side walls of the inner frame, and the fixed shaft 31A and the movable shaft 32A are pivotally supported, and when any one of these operation members is operated, the fixed member is fixed. It comprises a shaft 31A, a movable shaft 32A, and a comb 30A that rotates via the slider 12A that moves up and down.

Therefore, the second embodiment does not have the function of drawing the opposing outer side frames into the close contact state at the time of locking, but the other actions and effects are the same as those of the first embodiment. .

[0032]

[Effect of device]

 As is clear from the above description, the present invention has the following effects. (1) Locking and unlocking operations can be easily performed from either the left or right side of the inner frame simply by operating the knob of the operating member. Therefore, unlike the conventional case, the key is not required, and thus the key has to be stored, or the key has to be locked and unlocked. (2) The lock case can be installed in the inner frame after the slider, hook, stopper and other parts have been mounted on the lock case in advance. Therefore, the assembling work efficiency can be improved. (3) The lock case and other sliders and operating members have been made compact so that they can be easily combined. Therefore, the sickle lock can be attached to the inner frame in a short time. (4) Since the basic members are incorporated into the inner frame via the lock case, the appearance is not noticeable and the crime prevention effect can be expected. (5) Since the sickle is completely assembled into the inner frame through the lock case, the sickle itself can be made relatively compact. (6) Since the hook is pivotally supported via a plurality of movable shafts, the rotary shaft moves smoothly, the first movable shaft is laid horizontally in the horizontal long hole of the lock case, and the slider is tilted. Since it engages with the guide notch in the direction, when the slider descends, the hook can be moved to the indoor side and the outer frame can be drawn closer to the inner frame. (7) In the case of the embodiment provided with the hook stopper, the slider is prevented from freely moving by the stopper, so that the hook does not rotate in the releasing direction.
