 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a front view showing the configuration of the embodiment of the present invention when locked. In the figure, reference numeral 1 denotes a rotating body supported by a support shaft 3 fixed to a movable member 2, and a hook 5 and a small projection 6 which can be engaged with and disengaged from a fixed member 4 are provided on a part of the rotating body 1. Further, a fan-shaped projecting portion 7 is formed on the opposite side of the hook 5, and one side of this projecting portion 7 is a first locking portion 7a and the other side is a second locking portion 7b. Further, the rotating body 1 can be operated from the outside by a knob or the like (not shown).

Reference numeral 8 denotes a lock body that engages and disengages with respect to the first locking portion 7a and the second locking portion 7b. The locking body 8 is rotatably supported by a shaft 9 and is always attached in a clockwise direction by a spring (not shown). The receiving hole 10 is formed in the lower part. Reference numeral 11 is a solenoid body that operates the moving body 12 in response to an electric signal. The moving body 12 is constantly biased to the left by a spring (not shown), and a connecting body 13 partially fitted in the receiving hole 10 of the lock body 8 is provided at the tip of the moving body 12. There is. The connecting body 13 is provided with a hanging piece 14, and the lower end of the hanging piece 14 is brought into contact with the upper side of a leaf spring 15 having a through hole 15a in the middle of the lower part of the rotating body 1. The leaf spring 15 has one end fixed and has an elastic force that always urges it to rotate in the clockwise direction, and the other end is a curved portion 15 a that can abut the rotating body 1.

An engagement blocking piece 16 is rotatably supported on the upper part of the rotating body 1 so as to be rotatable. The engagement blocker 16 is formed with a through hole 18 whose opening coincides with the pair of locking holes 17a and 17b formed in the rotating body 1. Then, the pin 19 is fitted into the through hole 18 and any one of the locking holes 17a, 17 so that the engagement blocking body 16 is positioned with respect to the rotating body 1 as described later.

Next, the operation of the above embodiment will be described. The locked state is as shown in FIG. 1 regardless of the position of the engagement blocker 16. That is, the hook 5 is engaged with a part of the fixed member 4, and in this state, the first locking portion 7a of the rotating body 1 and the lock body 8 are engaged by receiving the force of the spring, It is fixedly held in this locked position. When the lock is released, the solenoid body 11 is operated by the ON signal of the switch (not shown), and the moving body 12 is pulled to the right. Then, the connecting body 13 rotates the lock body 8 counterclockwise, and the engagement between the first locking portion 7a and the lock body 8 is released. At this time, as shown in FIG. 2, the hanging piece 14 of the connecting body 13 enters into the through hole 15b of the leaf spring 15 to prevent the moving body 12 from moving to the left. Then, the curved portion 15a of the leaf spring 15 contacts the side portion of the rotating body 1. In this state, the rotating body 1 becomes free and is rotated clockwise so that the hook 5 is housed in the movable member 2 and the engagement between the movable member 2 and the fixed member 4 is released.

Here, in the case where the engagement blocker 16 is held by the pin 19 at the position of the locking hole 17a in the upper part of the rotating body 1, the rotating body 1 is rotated during the above-described rotation of the rotating body 1. When the small protrusion 6 and the curved portion 15a of the leaf spring 15 are brought into contact with each other and the leaf spring 15 is moved downward, the hanging piece 14 of the connecting body 13 and the inner periphery of the through hole 15b are disengaged, and the moving body 12 is left. Move towards. Then, as shown in FIG. 3, the connecting body 13 and the second locking portion 7b of the rotating body 1 are engaged with each other, the rotation of the rotating body 1 is prevented in this state, and the hook 5 is locked by the lock. It will be held stationary in the release position. In the above state, when the movable member 2 is pulled from the outside via a knob or the like, the hook 5 does not inadvertently move, so that the movable member 2 can be easily opened outward.

To lock again, switch on and pull the moving body 12 of the solenoid body 11 to the right to release the engagement between the lock body 8 and the second locking portion 7b. In this state, when the rotating body 1 is rotated counterclockwise by an external operation, the lock body 8, the coupling body 13, and the leaf spring 15 perform the above-described releasing operation. When the rotating body 1 is further rotated counterclockwise, the hook 5 engages with the fixing member 4. Then, the first locking portion 7a and the lock body 8 are again engaged, and the hook 5 is held at the locking position described above.

FIG. 4 shows a state in which the present embodiment is used for an opening / closing mechanism of the type in which the rotary body 1 may be free when the lock is released. In this case, the engagement blocker 16 is held by the pin 19 at the position of the locking hole 17b in the lower part of the rotating body 1. Therefore, at the time of unlocking, the engagement blocking body 16 exists between the second locking portion 7b of the rotating body 1 and the lock body 8, and the second locking portion 7b and the lock body 8 are engaged with each other. The rotor 1 is in a free state because it cannot be matched. The locking is performed by rotating the rotary body 1 in the counterclockwise direction and switching it on to operate the solenoid body 11 as described above. The shape, the installation position, and the moving method of the engagement blocker 16 are not limited to those in the above embodiment.
