Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an internal follower actuated by and cooperating with an actuating member, such as a lenomer handle, which acts on a locking member, e.g. Regarding electric locks. Movement of the follower can be blocked, so that the actuating member cannot act on the locking member. This invention is particularly but exclusively not limited to:
It is appropriate to apply this method to electronic locks and electric locks mainly used in guest rooms of hotels and the like.

What is often required of this type of lock is the ability to unlock and (
or) the locking is effected by electrical impulses, so that the lock can eventually be controlled remotely by electrical conductors or the like. It is also necessary to provide remote control of such locks by wireless transmission. In areas where it is difficult to supply paper power to control such locks, it is necessary to use IJ voltage to operate one lock.

What is desirable when using batteries in this way?

The goal is to minimize the electrical energy consumption of the lock so that the lock lasts as long as possible.

Several types of electric locks are already known. The best known type is operated by a so-called electric striking plate. In this case the striking plate is mounted on the frame of the door and has an electromagnet for actuating a flap which is adapted to be closed in order to deactivate the locking member of the lock. However, these types of locks have the disadvantage that the electric strike plate can be easily manipulated or destroyed, making it extremely easy for burglars to gain entry.

the locking member of the lock constitutes an extension of the core in the electromagnet;
And other types of electric locks that can be displaced into or out of the locking position are also already known.

However, in this case the core has to travel a long distance. Moreover, this type of lock requires a large amount of energy.

U.S. Patent No. 3. RI2 Otsu, Oko/No. 1 describes an electric lock that uses a drive device to open the door. However, this type of lock also. 1- for each unlocking operation
This requires a very large amount of energy since the drive must be operated for several seconds.

ISS Federal Republic of Patent Publication No. 2. Finished! No. 3 describes an electric lock controlled by an electromagnet. However, this type of lock also. When opening the door after removing the key, the electromagnet must be energized, which requires a large amount of energy.

Solutions other than those mentioned above also require large amounts of energy, as explained, resulting in a very short lifespan for the tube. Therefore, in such a lock, the locks must be replaced after ~3 months, which is not only a major drawback, but also increases costs by adopting such a replacement method. I will let you do it.

Therefore, when an electromagnetic lock or an electric lock is operated by a notch, it is necessary that the notch is as small as possible, and at the same time has a life as long as possible, preferably at least 7 years.

The above-mentioned drawback is that the driven body is provided with four parts, slots or protrusions adapted to cooperate with the movable locking plate-straddling locking shaft, and that said locking plate-straddling locking shaft is connected to the driven body. This can be overcome with the invention by being movable in the radial direction and movably mounted on the guide member of the lock case. The locking shaft straddling the locking plate is moved by the electromagnetic unit to a locking engagement position or a non-locking engagement position with the driven body. Advantageously, said electromagnetic unit comprises two electromagnets or drives with a rocking member arranged between them, said rocking member being supported at one end and latched at the other end to actuate a locking plate. It is engaged with the lock plate. Advantageously, the rocker member, which is preferably supported intermediate the two electromagnets or drives, has a width that decreases towards its free end, so that the rocker member and the rocker member are in contact with each other. The distance between the other electromagnet or drive increases in the direction towards the free end of the rocker member.

The rocking member is inclined as described above on both sides of its longitudinal axis, but with respect to the electromagnet or drive.

The side portion of the swinging member that is always in contact with the electromagnet or the drive device is designed to be parallel to the end face of the electromagnet or drive device that the swinging member is in contact with.

Preferably, the core of the magnet has an oval cross-section.

In this cross section, the major axis of the ellipse is oriented in the same direction as the longitudinal direction of the swinging member. According to this invention.

Only the electromagnets that attract the rocking member are supplied with current, and this is simply carried out until the rocking member reaches the desired position, at which point the power supply is stopped. Advantageously, the locking plate is provided with a guide member which cooperates with a corresponding guide member of the lock case to guide the locking plate relative to the lock case.

The electric lock according to the invention is designed to eliminate the various disadvantages described with existing locks and to provide security against burglary. At the same time, the electric lock according to the invention is adapted to utilize very little energy. The results of testing this electric lock.

Unlocking the lock simply requires jOms energization time, and locking also requires 20mb of energization time, so unlocking and subsequent locking requires uOmms.
It has been proven that energizing is sufficient.

This energization time is only a fraction of the energization time normally required to operate known locks.

Next, embodiments of the invention will be described in more detail with reference to the drawings.

The electric lock has a lock case t1, a lock portion 10, and a locking member /l, such as a cylinder lock (not shown). A follower body having a rectangular opening 17 is disposed inside the lock case, and a handrail (not shown) is attached to said opening 17. The driven body l is connected in a known manner to the locking member /l, so that the side door can only be opened if the driven body l is rotated. The lock plate can be used to lock the follower l so that it cannot rotate when not in operation. This locking plate λ passes through the guide member /, 2 provided in the lock case Δ.
The locking plate λ can be moved relative to the driven body / in the unlocking position, and the locking plate λ does not hinder the rotation of the driven body / in the unlocking position. Engage with a formed slot, recess or projection member 1 or similar member 13. Figure #c1 shows the lock plate in the retracted unlocked position in which the follower can be rotated to open the door. In order to bring the locking plate λ into this unlocked position, an electromagnetic member, such as an electromagnet or a drive r, is energized, thereby causing the shaft!
The swinging member ≠ attached to the lock case B comes into contact with the excited electromagnet or the core 14t of the drive device r.

In this connection, it should be pointed out that it is only necessary to power the electromagnet or the drive at a fraction of the KVi/s that attracts the rocker ring.

By energizing the electromagnet or the drive device f3, the rocking member ring rotates around the axis j and is supported by the electromagnet or the core /j of the drive device 3, and as a result, the locking plate λ is inserted into the groove of the driven member /. Hole 1
The lock is moved to the latching position at 3, thereby causing the driven body to rotate and slide. In order to allow movement of the locking plate 2, this locking plate λ is provided with an opening, a slot, an upwardly projecting lip or similar element /j which engages with the lower end 7 of the rocker member≠. The lock plate 2 is supported by the guide member /λ and a guide member (not shown) provided on the side wall of the lock case B. For this purpose, the lock plate 2 is provided with a protrusion (see FIG. 2). This Vi means that the thief must cut the lock plate λ in order to open the door. The lower end of the rocking member ≠ is also in contact with the elastic member it.

It is clear that locking and unlocking transfers electrical energy to an electromagnet or drive device 3. This can be done instantaneously by supplying J'. In experiments, 20 μS was sufficient to move the lock plate λ from one position to the other. The electric lock according to the invention thus saves power compared to other known locks and is therefore able to operate for a very long time with only seven batteries without having to replace the batteries many times.

Another important benefit of the electric lock according to the invention is that the lock can be tailored to standardized lock case dimensions.
