BRIEF DISCLOSURE OF THE INVENTION

This application is framed within the invention sector relating to security locks that are operated by remote control.
There is currently a certain rejection of glass doors with respect to the use of electric locks because the required power cables makes them visually unacceptable to many buyers.
One solution for these problems is that described in the background to the invention and which is mentioned in, for example, European Patent No 0737789 (cited in the IET of Patent 9801932 ) and Utility Model No 201230383 , which employs batteries to power the lock and the remote control.
In other words, these solutions affect the lock mechanism and not the strike box.
Although these documents resolve the above-mentioned problem, they have a serious drawback.
Thus, it is well-known that batteries regularly lose power because actuation of a lock mechanism requires a lot of electric power and so the same European Patent No 0737789 proposes the possibility of manually opening the lock.
This invention is an improvement over the previous documents because it resolves the stated problem because if affects the strike box and not the lock mechanism.
It should also be mentioned that the solutions that are currently employed for remote strike box opening require the wiring to be hidden, especially with glass doors. Thus, a market has developed that offers profiles, covers and adornments etc, for the sole purpose of dissimulating the wiring required to active the latches in said electric strike boxes, especially with glass doors.
Thus, the inventor has developed a device that reduces device consumption while it is not being used, so that battery lifetime is very significantly lengthened, so that no longer needs worrying for monitoring.
In this way, the invention remains in standby, but at predetermined intervals, it activates to check whether there is a valid instruction sent by the decoder, if not, it returns to standby mode to again save battery power.
Battery power is saved while the device is in standby, so that, depending on where it is installed, said time interval can be regulated which will reduce or increase useful battery lifetime.
One objective of this invention is a device for driving strike boxes, of the type that comprises a housing or container holding the various device elements, a power supply module with batteries, an actuation module with latch, characterised in that the power supply modules comprises a first integrated circuit that maintains a complete receiver power supply cycle by means of a low-frequency oscillation, with said operating cycle having a predetermined period, with said operating cycle equal to or less than the referred predetermined period, a signal reception module with at least one antenna and at least one receiver and because when a remote-control device sends a signal to the antenna it is taken to the receiver which applies it to a decoder and, if the signal is accepted, a command is sent to the drive module that comprises an electro-magnetic device that acting on the latch.

BRIEF DESCRIPTION OF THE DRAWINGS

In order to facilitate the explanation, this report is accompanied by two sheets of drawings that show a practical exemplary embodiment, which is cited as a non-limiting example of the scope of this invention:

Figure 1 is a view of a functional schematic of the device.
Figure 2 is a view of a functional schematic of the remote control.

SPECIFIC EXEMPLARY EMBODIMENT OF THIS INVENTION

Thus, Figure 1 illustrates power supply module 1 with batteries, signal reception module 2 with antenna 4 and receiver 5, actuation module 3 for a latch, remote-control device 7, decoder 8, electromagnetic device 19, solenoid 6, first integrated circuit 11, reference diode 10, second integrated circuit 12, first connector 13, third integrated circuit 18, transistor 14, terminals 15, 16 and diode 17.
Figure 2 represents remote-control device 7 with fourth integrated circuit 20, antenna 21 and power supplies 22 for the remote-control device.
Thus, a specific exemplary embodiment of the device for driving strike boxes of this invention would operate in the following manner.
The device basically comprises three modules, power supply 1 with batteries that provides the device with the power required for operation.
Similarly, power supply 1 comprises first integrated circuit 11 that maintains a complete receiver 5 power supply cycle by means of a low-frequency oscillation and second integrated circuit 12 that controls the power supply voltage and reference diode 10. This reference diode 10 detects the power supply voltage.
There is also signal reception module 2. In this embodiment, module 2 comprises one antenna 4, although it can be fitted with more. This module also comprises at least one receiver 5, in this embodiment it is one receiver that receives the signal from antenna 4.
Lastly, third module is the actuation module 3 that operates the latch that is activated by a command sent by remote control device 7 and subsequently accepted by the decoder 8 that authorises to act on latch (not shown) that open or close the door.
One of the greatest advantages of this invention is the fact it saves battery power.
This is achieved because the operating cycle is established for a predetermined period, for example, 1/3 of a second, in other words, the first integrated circuit 11 is activated every 1/3 of a second so that there is a first battery saving of 2/3.
Moreover, the active time of said operating cycle is equal to or less than the referred predetermined time, which means that the activation time per cycle can also be programmed to be less, so that, for example, if this were less by 1/8 of a second per cycle, this reduction would have to be applied to the 1/3 of a second duration of the cycle.
The approximate saving would be in the order of at least doubling the useful battery lifetime in the case of large communities of neighbours with a great deal of transit. In the case of individual dwellings, a level of saving could be attained so that batteries last several years.
When remote-control device 7 sends a signal to antenna 4, this transfers the signal to receiver 5, via first connector 13.
In this embodiment, this signal is sent to third integrated circuit 18 via resister 9, and then to decoder 8 which interprets the signal, sending said information to third integrated circuit 18, which will authorise the signal or not.
If the signal is accepted, a command is sent to actuation module 3 which drives electromagnetic device 19, for example, a solenoid, which then acting on the latch.
Electromagnetic device 19 comprises first transistor 14 that receives the command from third integrated circuit 18, which drives solenoid 6 connected to terminals 15, 16 and diode 17 connected in parallel with the outer coil to protect transistor 14 against reverse voltage pulses produced by solenoid 6 activation.
Optionally, the device could comprise a second transistor (not shown on the drawings) that when decoder 8 detects a valid signal, said second transistor produces dc to stop the oscillation.
In order to enhance antenna performance, especially if the device is on a glass door, antenna 5 is installed on one of the container sides so that any effect preventing radiofrequency propagation, such as a Faraday cage are avoided.
Remote-control device 7 (Figure 2) was designed so that any power supply 22 could be applied to it. This enables it to be installed, for example, on a wall and connected to the mains power, or to be a battery-powered control. In other words, remote-control device 7 can be both versatile and adaptable.
This requires fourth integrated circuit 20 with a stabiliser, so that when its voltage is increased, the radiated power from the stationary devices is increased and thus, remote-control device 7 range can be calibrated.
Moreover, in this embodiment, antenna 21 of remote-control device 7 is configured as a spiral because it has been demonstrated that this provide greater range and with low manufacturing costs. This obviously does not limit the use of a different type of antenna 21 that might be employed for specific requirements.
It should be fully understood that that illustrated circuits are manufactured examples of same which, while maintaining the technical specifications given in the claims, others can be configured by changing resisters, capacitors and diodes etc, changing the schematic, but with the same performance as previously described.
This invention describes a new device for driving strike boxes. The embodiments mentioned here do not limit this invention and it may have different applications and/or adaptations, all of which are within the scope of the following claims.
