Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to an electric lock used for lockers, safes, doors, etc.

[Background technology]

Conventionally, electric locks have been desired to have a locking mechanism that is unlocked by pulse input and manually reset from the viewpoint of safety and crime prevention.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide an electric lock having a locking mechanism that is unlocked by pulse input and manually reset.

[Disclosure of the invention]

The electric lock of the present invention has a solenoid 3 having a support portion 2 urged in a projecting direction by a return spring 4.
The proximal end 13 has a handle locking part 8 at the distal end, and a narrow protrusion 1a extends forward from the distal end, and the proximal end 13 is arranged so that the distal end extends in the protruding direction of the support part 2. An anchor 1 is rotatably connected to the tip of the support part 2 and further biased to rotate in one direction by a rotation spring 5; The anchor 1 is slidably engaged with the rotating side of the anchor 1 to restrict the anchor 1 in the protruding direction of the support portion 2, and the side of the protrusion 1a is moved back by the excitation of the solenoid 3. a stopper 6 that locks when the anchor 1 rotates, and a handle locking portion 8 that is disposed in a direction intersecting the moving direction of the anchor 1 and is in a retreating state, and that locks the handle locking portion 8 on the side in an advanced position by operating the front side. The lock handle 9 has a concave step 9a at its tip that allows the anchor 1 to move forward in a retreating position and locks on the side of the anchor 1, and the lock handle 9 has an intermediate portion pivotally supported. The stopper 6 has a tip abutting portion 10a that is pushed by the tip of the recessed step 9a in the forward position of 9, and is rotated by the operation of the tip abutting portion 10a.
The anchor 1 is provided with a return lever 10 that rotates the anchor 1 back against the rotation spring 5 so that the anchor 1 is located on the side of the anchor 1.

According to the configuration of the present invention, the reset state is a state in which the handle locking portion of the anchor is locked on the side of the lock handle, and when the lock handle is operated from this reset state to the backward position, the anchor is reset by the spring force of the return spring. The anchor moves forward and locks when the protrusion of the anchor advances. At this time, the recessed part of the lock handle is locked to the side of the anchor, so the manual lock handle cannot be pushed in. On the other hand, when unlocking, when the solenoid is driven, the anchor retreats, the rotation spring rotates the anchor, and the side of the protrusion engages with the stopper. With this anchor tilted, it is possible to operate the lock handle to the advanced position.
As a result of the advance movement, the end of the recessed part pushes the end abutting part of the return lever and returns the anchor to its original position against the rotation spring, and the handle locking part is locked to the side of the lock handle for reset. state.

Therefore, the lock can be locked by manually operating the lock handle in the reset state, and the lock can be unlocked by driving the solenoid, and the lock can be reset from the unlocked state by manually operating the manual lock handle. It is something.

An embodiment of the invention will be described with reference to FIGS. 1 to 6. In FIG. 1, 1 is an anchor, and this anchor 1 is connected to a solenoid 3 via a support part 2. The support part 2 is attached to the solenoid 3 via a return spring 4, and an anchor 1 having a wide base end 13 rotatably attached to the support part 2 by a shaft 12 is disposed in the protruding direction of the solenoid 3 and attached. to strengthen Further, a rotation spring 5 is attached between the support part 2 and the anchor 1, and urges the anchor 1 and the support part 2 to rotate in the right direction in FIG. 1 about a shaft 12.

In addition, a first stopper 6 is provided on the right side of the anchor 1.
is provided, and a second stopper 7 is provided with the anchor 1.
It is provided near the shoulder of the wide proximal end 13 of. Further, an L-shaped return lever 10 is pivotally supported outside the first stopper 6, and its rear end abuts against the side of the anchor 1.

As shown in FIG. 1, the anchor 1 has a pair of narrow protrusions 1a formed in a convex shape at its tip, thereby forming a handle locking part 8 between them. In the embodiment, the anchor 1 is formed with two plate-like protrusions 1a having the same shape and facing each other at a constant interval. and,
A lock handle 9 arranged in a direction perpendicular to the anchor 1 is fitted into the handle locking portion 8 and is locked to the anchor 1. The lock handle 9 is a support metal fitting 11
It is supported by , and is configured to be slidable in its longitudinal direction by manual operation.

When using an electric lock with such a configuration for a locker, safe, door, etc., for example, the electric lock is attached to the door side, and the protrusion 1a of the anchor 1 is removably inserted into the door frame side. Install the seat (not shown).

Next, the operation of this embodiment will be explained with reference to FIGS. 3 to 6. In these drawings, A is a perspective view of each operating state, and B is a plan view of the main parts.

3A and 3B show the anchor 1 in a set state, in which the tip of the recessed step 9a of the lock handle 9 is passed through the handle locking portion of the protrusion 1a of the anchor 1, and the lock handle 9 is inserted. The launching (returning) of the anchor 1 biased by the return spring 4 is prevented. It cannot be locked in this state.

To lock the lock, pull the lock handle 9 in the direction of the arrow using a key (not shown) or the like, as shown in FIGS. 4A and 4B. When this is done, the lock handle 9 comes out of the handle locking portion 8 of the anchor 1, and the released anchor 1 is pushed forward and locked. In this state, even if an attempt is made to return the lock handle 9 to its original position, the stepped portion 9a of the lock handle 9 comes into contact with the side surface 1b of the anchor body, preventing further intrusion.

Next, when unlocking, as shown in FIGS. 5A and 5B, a pulse input is applied to the solenoid 3 to energize it and pull the anchor 1 back in the direction of arrow A. At this time,
The anchor 1 is rotated in the direction of arrow B by the rotation spring 5, and the anchor shoulder 1c is engaged with the first stopper 6 to release the lock (mechanical lock release).
At this time, the return lever 10 rotates about the fulcrum in conjunction with the rotation of the anchor 1, and the tip contact portion 10
a is inclined toward the lock handle 9 side. In this state, the lock handle 9 can be operated forward. The pulse input is for protection of the solenoid 3.

Next, as shown in FIGS. 6A and 6B, when the lock handle 9 is pushed forward, the tip touches the tip contact portion 10a of the return lever 10, rotating the return lever 10 to its original position, and the return lever 10 is rotated to its original position. Rear end 1
0b rotates the anchor in the opposite direction to release the lock by the first stopper 6, and the lock handle 9 is fitted into the hole 8 between the protrusions 1a of the anchor 1. As a result, the state returns to the same state as shown in FIG. 3, and the resetting of the lock is completed.

〔Effect of the invention〕

According to this invention, the lock can be locked by manually operating the lock handle in the reset state, the lock can be unlocked by driving the solenoid, and the lock can be reset from the unlocked state by manually operating the manual lock handle.
