Description

[Detailed Description of the Invention] [Field of Industrial Application] ′ The present invention provides a method for unlocking the electric lock using a separate locking device when the electric lock is locked and the unlocking operation becomes impossible due to a power outage. Contains information on locking devices for emergency release of electric locks.

[Conventional technology]

Conventional electric locks have an auxiliary bar (1) to enable emergency unlocking in the event of a power outage. A battery is provided separately, and this auxiliary battery is charged when the battery is constantly energized, and the fully charged power is used. Also,
Since the charging control circuit is expensive, the electric lock is equipped with a cylindrical lock so that it can be unlocked with a key.

[The invention solves the problem 1. In the former case, the cost is high and it lacks practicality, and in the latter case, if a cylinder lock and a drive device driven by the cylinder lock are installed in the electric lock device, it becomes large and difficult to install. There are disadvantages such as making it difficult to cut the mounting holes.

[Means for solving problems]

A part, for example, driven by a cylinder lock on the column side, is driven by a ``5i''
A so-called electric locking device that is not equipped with a J device and can be locked only by electric driving force is provided, and the locking deadbolt provided in this electric locking device is released on the side opposite to this electric locking device, that is, on the door side. To provide an emergency release locking device capable of locking, and to allow a locking deadbolt to advance from the locking device at the same time as this locking device unlocks an electric locking device.

[For production]

A deadbolt protrudes from some electric locking devices when the lock is locked, and a sliding pin that is biased by a spring and slides inside the deadbolt is pushed by a drive cam rod and a pushing plate from the other locking device. 'L, When pushed by the release plate protruding from the outside of the lock device, this sliding pin retreats into the electric lock device, and at the same time, the engaging pin that comes into contact with the sliding pin and rises is pushed up to prevent unlocking. Since the member is pushed up, the tip of the unlocking prevention member rises up and comes off the deadbolt protrusion. At this time,
This deadbolt is automatically moved back in the unlocking direction by a spring.

Furthermore, when the release plate is advanced in this way, the drive cam rod, which is driven as the cylinder lock (not shown) rotates, pushes the deadbolt within the notch of the deadbolt in the locking device and protrudes in the locking direction. .

〔Example〕

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

In the figure, the arrow mark in FIG. It is a side view showing an unlocked state. Further, arrow B indicates a locking device provided on the door 3, and is a side view showing a partially cut away (-unlocked) state of the cover 4.

Figure 2 shows a side view of the electric locker and locking device B, with the electric locker's deadbolt 5 in the locked state. A side view of the electric locking device M and locking device B in which the elongated tip 6& of the release plate 6 in the device B is pushed into the emergency unlocking operation and the locking device fB is dead. It is.

FIG. 4 is a side view of the electric locking device B and the locking device B in which only the deadbolt 7 of the locking device B is locked.

FIG. 5 is a left side view of the lock device B shown in FIG.

The electric lock device M is provided with a dead bolt 5 which is pushed in the locking direction by a protrusion 10 of a rotating cam 9 rotated by the drive of a motor M in an electric lock case a, and a spring is installed inside the dead bolt 5. A sliding pin 5' that is biased by 11 and slides.
will be established. Further, in this dead bolt 5, this sliding pin 15' forms an annular groove 5'' with a sloped surface, and a retaining pin 12 that comes into contact with this groove 5'' and is raised.
will be established.

A protrusion 5b is formed on the side edge 5a of the deadbolt 5, and the protrusion 5b engages with the tip 13& of the unlocking preventing member 13 of the deadbolt 5, which is swingably supported on the electric lock case 8. In the secured state (see the second part), the deadbolt 5 is in a locked state. When this engaged state is released, the deadbolt 5 is unlocked by the spring 14 that always urges it in the unlocking direction.

In this way, the protrusion 5b of the deadbolt 5 and the unlocking prevention member 1
3 is disengaged because when the sliding pin 5' retreats, the engagement pin 12 slides on the slope of the groove 5'' (raises at 7 and pushes up the unlocking prevention member 13). This is because the unlocking preventing member 13 and the protrusion 5b are designed to come off at the same time.

The sliding pin 5' is moved back by the release plate 6 of the locking device B provided on the door 3 when the electric locking device is in the locked state.
This can be done when the tip 6& of the locking device is moved toward the sliding pin 5' within the locking device case 16.

This locking device B includes a driving cam rod 17 which is rotated by a cylinder lock (not shown) in a locking device case 16, and this driving cam rod 17 is engaged with the driving cam rod 17. In addition, one end 19m is connected to the driving cam rod 17 and the pin 15 to the upper part of the dead bolt T forming the notch IB.
A pushing plate 19 connected to the pushing plate 19 is provided, and a pin 20 is protrudingly installed on the other end 19b of this pushing plate 19.
Formed in 1. The locking device case 1 is inserted into the elongated hole 6b.
This pushing plate 1 is inserted into the bending groove 161L formed in 6.
9 is pushed by the four-drive cam rod 1T as shown in FIGS.
The bolt 5 slides in the side direction. In addition, a rectangular opening 160 formed at the front 16b of the locking device case 16 is connected to the closing plate 22, which is biased by a spring 21, to the locking device case 16.
At the same time, a small hole 22& is formed in this closing plate 22, and the tip 15a of the release plate 6 moves forward and backward through this small hole 22&, so that the opening 160 is closed by the closing plate 22. (See Figure 5).

Notch 1BVC of deadbolt T in locking device case 1B
When the 1ltK moving cam rod 17 is engaged (7) and this driving cam rod 1T is rotated by the rotational operation of the cylinder lock (see FIG. 4), the dead pole 7 becomes locked.

Further, at the same time as the rotation operation of the cylinder lock, the first section power lever 17 moves the push plate 19 and slides the release plate 15, so that the tip 15 of the release plate 15! Sliding pin 5' inside the deadbolt 5 on the entrance side of the electric lock device where L is locked
This sliding pin 5I is pushed while making contact with it 17. As a result, the sliding pin 5' is moved to the retaining pin 1 as described above.
2 rises and pushes up the unlocking preventing member 13, so the engagement state between the tip 13& of the unlocking preventing member 13 and the projection 5b of the deadbolt 5 is released, and the deadbolt 5 is released. It is moved back by the spring 14 and becomes unlocked.

〔Effect of the invention〕

As described above, the present invention provides a locking device at a position facing the electric locking device, and the sliding pin of the deadbolt in the electric locking device is retracted by the release plate in the locking device. Since the lock can be unlocked without installing a charging control circuit,
It is inexpensive, and since the deadbolt extends from the locking device side to lock the lock, it is effective in ensuring safety even in the event of a power outage.
