Description

DEVICE AND METHOD FOR THE TRANSMISSION OF DATA AND ELECTRIC ENERGY BETWEEN A KEY AND THE CYLINDER OF A LOCK
DESCRIPTION
The present finding concerns a device and a method for the transfer of electric energy and data between the key and the cylinder of a lock.
It is well known that numerous types of locks exist on the market at present, that are normally equipped with a rotor, a stator, mechanical and/or electromechanical double locks, and a key to activate the lock (open-closed) .
In the electromechanical locks electric contacts are normally present to transmit both data and electric energy from the key to the cylinder of the lock and vice-versa.
The definition provided above makes it easy to understand how the use of electric contacts in an electromechanical type lock present numerous problems.
For example, if the lock is mounted in a polluted environment, the presence of dust, oxides, liquids, lubricants and similar products that deposit either on the key or the lock will not permit the energy and data transmission through, the electric contacts, including all the problems that can arise in these conditions.
Accordingly, in order to always obtain correct performance with electromechanical type locks, the electric contacts on the lock must be cleaned frequently.
Said definition above results in frequent and expensive maintenance operations to maintain the electric contacts clean, in order to ensure electric contact conduction.
This situation provokes considerable problems, for example, in the case of large-scale buildings with numerous locks .
The aim of the present finding is to eliminate the problems described above in well known electromechanical locks .
In relation to this aim, an important object of the finding is to create a device and method for transmitting electric energy and data between a key and the cylinder of a lock, where this transmission does not require an ohmic contact .
A further object of the finding is to create a device and a method in which the data and electric energy can be transmitted even where dust, oxides, liquids, lubricants and similar products are present .
A further object of the finding is to create a device and method that permit the use of the locks even in environments with a high pollution level.
A further object of the finding is to create a device and method in which the maintenance of the lock circuit is practically inexistent thus providing considerable savings in the cost of programmed maintenance .
A further object of the finding is to create a device and method that permit high-level electric transmission between the key and the cylinder of the lock and vice-versa.
Last but not least object of the finding is to create a device and method that provide a reliable lock that requires little maintenance at low cost.
This aim, as well as these and other objects are achieved by a device and method for data and electric energy transmission between a key and the cylinder of a lock, characterised in that it comprises a first electromagnetic circuit associated with said key, and a second electromagnetic circuit associated with said cylinder, said first and second electromagnetic circuit being equipped with connection systems for mutual connection during the insertion of said key in said cylinder to create a third electromagnetic circuit for transmission of at least the electric energy from the primary winding of said first circuit to the secondary [winding] of said second circuit .
Another object of the present finding is also a method for transmitting data and electric energy between the key and the cylinder of a lock, characterised in that it consists in the insertion of said key equipped with a first electromagnetic circuit into said cylinder equipped with a second electromagnetic circuit, in activating a third electromagnetic circuit obtained through the coupling of said first and second electromagnetic circuits, in transmitting the code of said key to said cylinder through the application to said first electromagnetic circuit of a time variable voltage, having the same frequency band as said second electromagnetic circuit and amplitude proportional to the ratio between the number of turns of the windings of said first and second electromagnetic circuits, in recognising said key code, and in sending electric energy in the form of a magnetic flux to the shutter of said lock for activation.
Further characteristics and advantages of this invention will be more evident from the description of a preferred but not limiting embodiment of the device and the method for electric energy and data transmission between a key and the cylinder of a lock according to the finding, illustrated in an indicative but in no way limitative manner in the enclosed drawings wherein:
- figure 1 is a view in perspective of the key according to the finding;
- figure 2 is a vertical front view of the key according to the finding;
- figure 3 is a view in perspective of the cylinder according to the finding;
- figure 4 is a plan view of the first and second electromagnetic circuits according to the finding,-
- figure 5 is a view in perspective of a different embodiment of the cylinder and the key according to the finding;
- figure 6 is a plan view of a different embodiment of the first and second electromagnetic circuits according to the finding; and
- figures from 7 to 9 show diagrammatically certain function applications according to the finding.
With particular reference to the figures described above, the device for data and electric energy transmission between the key 1, and the cylinder 3 of a lock, not illustrated, comprises a first electromagnetic circuit Al associated with key 1, and a second electromagnetic circuit A2 associated with cylinder 3.
The first and second electromagnetic circuits Al and A2 include connection means for mutual connection during the insertion of the key 1 inside slot A3 of cylinder 3 so that it creates a third electromagnetic circuit 4 adapted to transmit data and electric energy from the primary winding A6 of the first circuit, to the secondary A7 of the second circuit .
In short, when a first electromagnetic circuit is coupled with the second electromagnetic circuit, this forms an electric transformer in which the energy put on in the primary winding A6 is transferred to the secondary winding A7 in the form of a magnetic flux which is suitably sent to a circuit of ferromagnetic material, or advantageously created using ferrite .
Advantageously, the use of ferrite makes it possible to use high frequency . in order to obtain a band that is adequate for data transmission and high performance for energy transmission.
In particular, the first and second electromagnetic circuits, respectively comprise a first and second bar A4 and A5 that result as connected to each other.
In the case illustrated as an example, the first and second bars also result as wound from the coil Aβ and A7.
The third electromagnetic circuit 4 is thus formed by the mutual coupling of the first and second magnetic circuits forming a closed circuit.
Figures 5 and 6 show a different embodiment of the circuit device according to the finding.
Coil All of the first electromagnetic circuit A9 is subject to a time variable voltage with the same or different frequency band as the second electromagnetic circuit A8 , and an amplitude proportional to the ratio between the number of turns of primary winding All, compared to the secondary winding AlO to permit data transmission from key 1 to cylinder 3 and vice-versa.
In short, the supply transfer from the key to the cylinder generates a magnetic flux through the primary winding All that is sent to the ferromagnetic circuit by passing it through the secondary winding AlO into which an electromotive force is induced, able to supply the electronic circuit and the actuator located inside the cylinder.
As stated previously, the data is transmitted using one of the classical electric transmission theory methods such as frequency modulation, amplitude, PWM phase, or any other method thus permitting data transmission from the key to the cylinder and vice-versa.
Data is transmitted in digital and/or analogue form.
Lastly, it should be emphasised that the turns are produced using appropriately insulated conductor wiring. One of the aims of the present invention is also a method for transmitting data and electric energy between a key and a standard cylinder of a lock as shown schematically in the figures 7 to 9.
In particular, the method consists in inserting the key equipped with a first electromagnetic circuit Al into the cylinder equipped with a second electromagnetic circuit A2.
Subsequently, a third electromagnetic circuit 4 is activated through the coupling of the first and second electromagnetic circuit.
The key code is transmitted to the cylinder through the application to the first electromagnetic circuit of a time variable voltage with the same or a different frequency band as the second circuit and an amplitude proportional to the ratio between the number of winding turns of the first and second electromagnetic circuits.
At this point the key code is recognised and the necessary electric energy is transmitted in the form of a magnetic flux to activate the lock actuator.
As well as activating the actuator, the energy taken from the secondary magnetic circuit coil must also provide the supply for the relative electronic circuits for decoding the electronic key code.
Lastly the circuit is switched off after actuator rotation, even possibly with the key inserted.
Advantageously, in the device and method for data and electric energy transmission between the key and cylinder of the lock, a signal applied to the primary magnetic circuit coil, supplies both the energy and the data on the secondary magnetic circuit winding.
Practically speaking, it has been demonstrated that the device according to the finding is particularly advantageous for eliminating all the drawbacks of electromagnetic locks mainly due to the use of electric contacts.
The finding according to this concept can be subject to numerous modifications and variants while remaining within the inventive idea; moreover, all components can be replaced by technically equivalent elements.
Practically speaking, the materials employed as well as the size of the elements can vary according to necessity and the technical state of the art.
