BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric lock used for locker doors of various facilities such as houses and companies.

[0002]

2. Description of the Related Art Generally, an electric lock is provided with a light emitting diode (LED) to indicate a locked or unlocked state. For example, as shown in FIG. 15, the hook 1 fixed to a part of the door
The lock cam 4 is rotatably supported by a shaft 3 arranged parallel to the longitudinal direction of the lock body 2, and a plunger 6 driven by a solenoid 5 can project into the rotation surface of the lock cam 4. It is arranged. The LED 7 is provided on the front side of the lock body 2. In the electric lock having such a structure, in the case shown in FIG. 15, the hook 1 is locked by the lock cam 4. That is, the extended portion of the plunger 6 projects to the rotation surface of the lock cam 4,
The rotation of the lock cam is restricted. FIG. 16 is a cross-sectional view of this state seen from above. The lock cam 4 holding the hook 1 is locked by the extending portion of the protruding plunger 6. FIG. 17 is a cross-sectional view showing a state in which the plunger 6 is retracted, the lock cam 4 is rotated, and the hook 1 is released.

[0003]

Therefore, when the above-mentioned conventional electric lock is used for the right-opening door, FIGS.
The LED 7 is located below the lock cam 4 as shown in FIG. However, when this lock is used for a left-opening door, it can be used, but the position of the LED is reversed. That is, in FIG. 15, the lock cams 4, L
The ED 7, the plunger 6, and the solenoid 5 are arranged, but when used for a reverse-opening door, the arrangement is the reverse of this. For this reason, the same lock cannot be used also as a door that opens left and right. In other words, the position of the LED and the size of the frame could not be met without preparing electric locks conforming to the standards of the left and right sides. This is very wasteful from the standpoint of inventory management because multiple types of locks must be prepared.

The object of the present invention was made in view of the above-mentioned drawbacks of the prior art. An electric lock in which the position of the light emitting diode does not change even if it is used for both right-opening and left-opening doors with one electric lock. To provide.

As shown in an enlarged view in FIG. 11, the manual lever 16 has a head portion 16a protruding from the lock body and an inclined surface portion 16b abutting against the tip projection 13c of the slide cam 13.
And a narrow width portion 16c into which the coil spring 21 is inserted are formed.
a is urged in the direction of protruding from the lock body. The lock cam 15 has a groove 15a that engages with a hook 19 (not shown).
Engagement groove 1 that engages with pin hole 15b and slide cam 13
5c is formed, and two plate-shaped members are integrally formed in parallel with each other with the connecting member 15d interposed therebetween. Also, the torsion spring 22
Has a locking hole 15e for locking one end thereof.

The operation of the electric lock configured as described above will be described. First, as shown in FIG. 1, when the hook 19 comes in from the direction of the arrow A, the lock cam 15 at the position shown by the chain double-dashed line rotates about the pin 14 to the position shown by the solid line. Engaging end 15c of the lock cam 15
Is locked at the tip of the slide cam 13 that has once retracted. Therefore, the hook 19 is locked and locked in the engagement groove 15a and the recess 10a of the lock body. When electrically unlocking, press the solenoid 1
Energize 2. When the solenoid 12 is energized, the plunger 11 retreats against the coil spring 20, causing the slide cam 13 to retreat at the same time. Slide cam 13
When is retracted, it disengages from the engagement end 15c of the lock cam 15 and moves to the position indicated by the chain double-dashed line by the spring force of the torsion spring 22.

When manually releasing the lock, the manual lever 16 is pushed. When the manual lever 16 is pressed down, the inclined surface portion 16b comes into contact with the tip projection 13c of the slide cam 13 and retracts the slide cam 13. When the slide cam 13 retracts, the engaging end 15c of the lock cam 15 becomes free, and the hook 19 that has been engaged is released, as described above.

FIG. 12 shows a case where the hook 19 is locked to both of the two lock cams 15. In this way, when the hook 19 is locked to both the lock cams 15, the door can be locked more reliably. Further, in the electric lock of the present invention, the rotation shaft of the lock cam 15 is arranged orthogonally to the longitudinal direction of the lock body. Therefore, it is possible to use the right-opening door or the left-opening door without changing the mounting position of the electric lock. Therefore, the position of the light emitting diode 17 does not change whether it is used for the right-opening door or the left-opening door, and one electric lock can handle both. FIG. 13 shows a case where the hook 19 is arranged so as to be engaged with one of the lock cams 15 on the right side. Further, FIG. 14 shows a case where the hook 19 is arranged so as to be engaged with one left side of the lock cam 15. In this way, when the lock cam 15 is arranged so as to be engaged with one piece, the size of the rocker on the frame side can be reduced, and a compact structure can be achieved.

Further, the light emitting diode 17 is turned on or off by a switch (not shown) which is turned on and off by the operating piece 15f of the lock cam 15. The present invention is not limited to the above embodiments, and various design changes can be made within the technical scope of the present invention.
