Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electric lock device that is installed on a residential door and that can be unlocked by remote control.

[Conventional technology]

Conventional electric locking devices use a drive source such as a motor or a solenoid to move the dead bolt forward in the locking direction or backward in the unlocking direction. In addition, emergency operations in the event of a power outage are as follows:
The unlocking operation is performed using a battery that is always charged for use in the event of a power outage.

[Problem that the invention seeks to solve]

The problem with such electric locks that use electricity is that they cannot be unlocked during a power outage, and for this reason it is necessary to install an emergency auxiliary battery inside the electric lock. be.
Having a built-in auxiliary battery in this way not only increases the size of the electric lock and makes it difficult to attach it to the door, but the weight of the electric lock puts a load on the hinge that holds the door in place, making it difficult to open and close the door. There are drawbacks such as the inability to operate smoothly.

[Purpose of the invention]

The purpose of the present invention has been achieved by focusing on the above-mentioned drawbacks.The purpose of the present invention is to operate a cylinder lock provided on the door side with a key in the event of a power outage, and to operate an emergency unlocking pin provided on the cylinder lock with the key. The tip of this actuating pin is placed in a position where it can push the advancing/retracting pin installed in the dead bolt in the electric lock device, and when this advancing/retracting pin is retracted by the actuating pin, this operation occurs. The vertical movement pin that interlocks with the pin,
At the same time as the blocking member that prevents the deadbolt from retreating is raised, this blocking member is removed from the deadbolt, so the spring that biases the deadbolt can automatically move the deadbolt back in the unlocking direction. The purpose is to do so.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

In the drawings, FIG. 1 is a side view of the electric lock device A and the emergency unlocking device B, that is, a side view showing the operating state when the dead bolt is emergency unlocked in the event of a power outage. FIG. 2 is a side view of the electric lock device A, FIG. 3 is a right side view of FIG. 2, and FIGS. 4 to 7 are diagrams of the dead bolt operating state.
5 is a state diagram showing the state in the unlocked position, FIG. 5 is a state diagram showing the state being moved to the locked position, FIG. 6 is a state diagram showing the locked position state, and FIG. 7 is a state diagram showing the start of movement to the unlocked position.

2 and 3, a solenoid 2 that operates when energized is provided in the upper part of the case body 1 of the electric lock device A, and an electric wire H is connected to this solenoid 2, and together with the electric wire H' of the motor M, the case body Wire to external connector C of 1.

A blocking member 5 that prevents the dead bolt 4 from advancing is attached to the tip of the plunger 3 that is provided on the solenoid 2 and that moves back and forth, and one end 5a of this blocking member 5 is latched to the wall surface 1' of the case body 1. It is now possible to swing freely. Further, the other end 5b of the blocking member 5 is notched.

A dead bolt 4 that moves forward and backward from the case body 1 is slidably provided at the bottom of the blocking member 5 at the bottom of the solenoid 2, and a protrusion 4a is formed on the upper side wall surface 4' of the dead bolt 4, so that the dead bolt 4 is slidably moved forward and backward from the case body 1. The protrusion 4a is located at a position where it engages with the notch in the other end 5b of the blocking member 5.

A reciprocating pin 6 is provided inside the dead bolt 4 to slide in a through hole 4'', and an annular groove 6' having an annular slope is provided at the rear of the retracting pin 6. This advancing/retracting pin 6 is always biased by a spring 7 within the dead bolt 4. Also, a vertically movable pin 8 having a tapered tip is inserted into the annular groove 6' of the advancing/retracting pin 6, passing through the dead bolt 4. When the reciprocating pin 6 moves, the vertically movable pin 8 is raised and pushes the blocking member 5 upward.

In addition, in the locking operation of the dead bolt 4,
A rotary cam 9 that moves the dead bolt 4 toward the locked position and is driven by a motor M is provided at the bottom of the dead bolt 4. A push pin 10 implanted in the rotary cam 9 moves the dead bolt 4 toward The rotary cam 9 contacts the notch 4 at the rear end and rotates when the motor M drives the dead bolt 4.
is pushed by the push pin 10, advances to the outside of the case body 1, and becomes locked.

In addition, in order to stop the rotary cam 9 at the original position when it rotates once, a notch recess 9a is bored in the circumferential wall surface 9' of the rotary cam 9, and a micro Switch MS electrical contact piece 1
1 is arranged so that it can move forward and backward.

Therefore, when remotely controlled from the outside, the motor M
becomes energized, so by driving motor M,
Rotating cam 9 rotates. At this time, the push pin 10 of the rotating cam 9 pushes the rear end of the dead bolt 4 and moves the dead bolt 4 in the locking direction (in the direction of arrow A). When the dead bolt 4 is located at the locked position, the tip 5b of the blocking member 5 is engaged with the protrusion 4a formed on the dead bolt 4, thereby preventing the dead bolt 4 from retreating. Next, when unlocking, when the solenoid 2 is energized by remote control, the plunger 3 is driven, so that the blocking member 5 attached to the plunger 3 is moved upward. At this time, the blocking member 5 and the protrusion 4a of the dead bolt 4
At the same time as the locked state is released, the lock is moved in the unlocking direction (arrow B direction).

Next, to explain emergency unlocking in the event of a power outage, in Fig. 1, the door (not shown) is provided with a
In addition, an electric lock device A has an actuation pin 15 fixed to the side end of a slide plate 14 provided on the case 13 of the emergency unlocking device B, and this actuation pin 15 is provided on the side of a column frame (not shown). It is arranged at a position facing the advance/retreat pin 6 of the dead bolt 4 inside. Further, this slide plate 14 is also provided with an operating pin 15 so as to automatically return to its original position.
A spring 16 is fitted, one end of which abuts an upright piece 17 formed on the case 13, and is stretched between the upright piece 17 and the slide plate 14.

In addition, an opening 18 is formed in this slide plate 14, and a notched elongated hole 19 is provided.
The pin 21 of the drive cam 20 is inserted into the cam 9 so as to be rotatable. A square shaft (not shown) provided at the rear of a cylinder lock (not shown) is fitted into the through hole 22 of the drive cam 20, and a key (not shown) is inserted into the cylinder lock and rotated. When this drive cam 2
0 rotates at the same time and moves the slide plate 14 while resisting the spring 16. At this time, operating pin 1
5 pushes the retractable pin 6 in the dead bolt 4, so that the retractable pin 6 moves backward while resisting the spring 7 (see FIG. 1). At this time, the vertically movable pin 8 is pushed up from the annular groove 6' of the advancing/retracting pin 6, and at the same time, this vertically movable pin 8 pushes up the blocking member 5, so that it is engaged with the tip 5b of this blocking member 5 and is prevented from retreating. The blocked dead bolt 4 is no longer locked with the protrusion 4a, and the dead bolt 4 becomes movable. Since the spring 12 is inserted between the rear end of the dead bolt 4 and the case body 1, the dead bolt 4 is biased in the direction of sinking into the case body 1, and the dead bolt 4 is released. be locked. In this way, the problem at the time of power outage can be solved by operating another key.

〔Effect of the invention〕

As described above, the present invention provides an electric lock device A on the frame side of a column, and an emergency unlocking device B that is operated by another key at a position opposite to the electric lock device A. In addition to reducing the applied load, in the event of a power outage, the advancing/retracting pin built into the dead bolt can be moved back by the actuating pin provided on the slide plate, and as the actuating pin moves back, the vertical moving pin rises and the dead bolt is moved. Since the dead bolt can be unlocked by releasing the blocking member that is engaged with the protrusion, the electric lock device can be made smaller and can be easily installed on the frame. It is something that plays.
