Description

LOCK WITH CYLINDER INSERT WITH ELECTRIC TRIGGER

The subject of the invention is a lock with a cylindrical insert with electric actuation. The cylindrical insert armor has the same external mounting dimensions as a normal cylindrical insert designed to be unlocked and locked with a key, but does not have an internal part with pins and slots to insert a key. The lock according to the invention can be used in new installations, but it is also possible to successfully replace a standard cylindrical insert in a normal recessed lock with a custom cylindrical insert according to the invention and to enable electrical actuation (unlocking and locking of the lock) by an electric actuator such as a sensor switch based on fingerprint or. via a wireless remote control. The invention belongs to class E05B 49/00 of the international patent classification.

is A technical problem that the present invention successfully solves is the embodiment of a cylindrical insert with electric actuation, which will primarily enable easy replacement of a standard cylindrical locking key with a key so that the key will not be required to lock the door, but the door will be unlocked or locked with a fingerprint reader or via a wireless remote control. The invention also allows for more reliable operation and lower power consumption.

For well-known electromechanical locks (eg BurgVVachter), the outer knob is mounted on a thin brass axle, and the construction also uses a small mechanical lock on the outside of the door that is built into the armor in the event of a battery failure. Also, a wireless control receiving antenna is mounted on the inside of the door, which does not allow the use of such electromechanical door locks for metal doors, but only for wooden or plastic doors, since it cancels remote wireless controls (Faraday cage) for metal doors.

The problem of using an electric lock for unlocking and locking doors in the well-known implementation solutions that are commercially available is that their use requires an electrical signal on both sides of the door. The solution according to the invention, however, allows the door to be locked and unlocked from the inside without the need for an electrical signal, which means great energy savings and a more reliable and long-lasting operation. All known solutions of electronic locks so far have a locking clutch at their core, and in the present invention, the clutch is in the form of a wedge outside the core.

The invention will be explained in detail on the basis of an embodiment and the accompanying drawings, of which:

The electrically actuated cylinder lock lock according to the invention consists of a modified cylinder insert 1, an inner button 2 and an external button 3. The inner button 2 houses a mechanical unlocking and locking mechanism, an electronic part of the lock and a battery.

2o The inner button 2 and the outer button 3 are connected to each other by an axis 4 passing through the armor 5 of the cylindrical insert and a beard 9. The axis 4 has grooves 6 which allow the axis 4 to be mounted in different lengths of the armor 5. At the end of the axis 4 which is connected to the inner button 2, a closing 7 · shaped hexagonal prism is formed, which fits into the same shaped opening 8 in the inner button 2. Such connection of the inner button 2 and axis 4 with the outer button 3 allows by turning the inner knob 2 or the outer knob 3, we can move the beard 9 in the cylinder insert 1 to unlock or lock the lock.

Moving or the rotation of the assembly of the outer knob 3, the axis 4 and the inner knob 2 is conditioned by the position of the locking pin 10 with the truncated tip 11 located in the inner knob 2.

The locking pin 10 has a truncated tip 11 at one end, which passes through the plate 12 to hold the tip of the pin 10, and the other end of the pin 10 is cut and connected to a properly rectangular axis 13 of the electric motor 15 by a gearbox. A spring 14 is mounted between the seat 16 of the locking pin 10 and the electric motor 15 with the gear unit.

The assembly of the locking pin 10 with the electric motor 15 with the gear unit is located in the inner button 2 outside the main connecting axis 4 by looking at the truncated tip 11 of the closing pin 10 from the front surface of the inner button 2 and when rotating the composition of the outer button 3, the axis 4 and the inner Button 2, fits into the shell 5 of the cylinder insert.

The position of the truncated tip 11 of the locking pin 10 can be rotated by 20 operating the electric motor 15 by 220 ° to two extreme positions. In one extreme position of the truncated tip 11 with respect to armor 5, the locking pin 10 is inserted into the inner button 2. In this position, the rotation of the outer button 3, the axis 4 and the inner button 2 can be unlocked or locked, depending on the direction in which said composition. In the other extreme position of the truncated tip 11 relative to the armor 5, however, the locking pin 10 does not fit into the inner knob 2 and thus prevents the lock from being unlocked or locked.

In this way, a signal from an electrical trigger, such as a sensor capacitive switch based on the fingerprint on the outer button 3, or via a wireless remote actuator, an electric motor 15 is actuated by a reducer that moves the position of the truncated tip 11 of the locking pin

10.

ίο If we want to rotate the assembly of the outer knob 3, axle 4 and the inner knob 2 manually (without using the signal from the electric actuator), a ring 17 is also mounted on the inner knob 2 for manual unlocking of the locking pin 10. The ring 17 is mounted via a spring 18 to the inner button housing 2.

is The manual unlocking of the locking pin 10 enables us to manually lock or unlock the lock from the inside without an electrical signal. The operation of manual unblocking is shown in Figure 5.

Inside the inner button 2, in addition to the system with the locking pin 10, there is an electronic lock part and a corresponding battery. The block diagram of the electronic part is shown in Figure 6. The electronic part consists of a microcontroller circuit

20, to which an encoder 21 of a sensor capacitive switch based on a fingerprint, a memory circuit 22 and an RF receiver is connected 23. A microcontroller circuit 20 based on a received signal from a sensor capacitive switch based on a fingerprint on an external button 3, respectively. via the signal of the wireless remote actuator, control via the circuit 24 an electric motor 15 with a gearbox.

In addition to the above, the electronic part also has visual 25 and audio 26 signaling of operation and proper power supply by means of the battery 27, built into the internal button 2. or. with auxiliary power 28 via boost converter 29,

The cylindrical insert lock according to the invention operates on the principle of communication of an external sensor capacitive switch based on an io fingerprint on an external button 3 or. a wireless remote control unit with an electronic part located in the inner button 2, which has a system with a locking pin 10 and an electric motor 15 with a gearbox. The electronic part is mounted deep into the door leaf and cannot be accessed when the door is closed. Communication between the external sensor and the internal electronic part is encrypted, which means that the unlocking of the door from the outside cannot be triggered even if the lock is removed from the door.

The electronic part mounted in the inner button 2 is connected to the hole in the axis 4 by a sensor capacitive switch based on the fingerprint mounted on the outer button 3. In addition, the antenna of the electronic part lies in the hole of the axis 4, which allows undisturbed actuation of the electronic part by means of a wireless remote control.

The placement of a surface capacitive switch based on the fingerprint on the outer button 3 is located on the back of the button holder 3, which allows the user to place his finger on the sensor at the same instant as he grips the holder. The door unlocks immediately.

It is extremely easy to manage the settings and is done with two buttons built into the back of the holder on the external button 3. You can add administrators and users, delete them from memory, choose which relays the individual fingerprint will trigger, and choose the mode economical energy consumption. When no function is performed, the electronic part is in io standby mode, which means that the door is unlocked as soon as the fingerprint stored in the device memory is placed on the sensor.

The first three memorial sites are for administrators (owners and managers). Three fingerprints of the same person can be entered, or several different fingers of different persons can be entered in any combination. You can only enter and delete users in the presence of an administrator.
