BRIEF DESCRIPTION OF THE INVENTION

The present application is framed within the sector of inventions related to security locks that are operated by remote control.

At present, glass doors have a certain rejection regarding the use of electric strikes, because the wiring that is needed for their power means that visually it is not accepted by many buyers.

A solution to these problems are the solutions that are pointed out in the background of the invention and which are mentioned, for example, in European Patent No. ^Q 0737789 (cited in the EIT of Patent 9801932) and the Utility Model No. ^Q 201230383 , which have batteries to power both the lock and a remote control.

That is to say, these are solutions that affect the mechanism of the lock and not the lock.

Although these documents would solve the problem mentioned above, they have a serious drawback.

Thus, it is known that the batteries or batteries that are used are used up very often, since the operation of a lock mechanism supposes a great energy consumption and hence the European Patent No. ^Q 0737789 proposes the possibility of opening the lock manually.

The present invention improves the previous documents because it solves the problem pointed out, since it affects the lock and not the mechanism of the lock. It should also be noted that the solutions that are currently used for remote opening of locks, need to hide the wiring, especially in glass doors. This has developed a market that offers profiles, covers, trim, etc., whose only mission is to hide the necessary wiring to activate the latch of said electric strikes, especially on glass doors.

Thus, the inventor has developed a device that reduces the consumption of the installation by the device while it is not being used, so that the battery gets very long in time, and its control does not have to be a concern.

In this way, the invention remains on hold and from time to time, predetermined, is activated to check if there is a valid instruction sent by the decoder, and if there is no such valid instruction it returns again to the waiting state, consequently saving the energy of the batteries.

All the time that the device is on standby is a battery that is saved, hence depending on the place in which it is located, this period of time can be regulated and therefore shorten or increase the life of the batteries.

It is an object of the present invention a device for the operation of strikes, of the type comprising a housing or container where the different elements of the device are arranged, a power module with batteries, an actuation module of a latch, characterized in that The power module comprises: a first integrated circuit that maintains a complete duty cycle of the receiver's power by means of a low frequency oscillation, said duty cycle being for a predetermined period, with an activity time said duty cycle equal or less at the aforementioned 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 transfers the signal to receiver that is supplied to a decoder and if the accepted signal is sent an order to the drive module comprising an electromagnetic device that acts on a latch.

BRIEF DESCRIPTION OF THE DRAWINGS

In order to facilitate the explanation, two sheets of drawings are attached herein in which a practical case of embodiment has been represented, which is cited by way of example, not limiting the scope of the present invention:

- Figure 1 is a view of a scheme of operation of the device

- Figure 2 is a view of a scheme of operation of a remote control.

CONCRETE REALIZATION OF THIS INVENTION

Thus, in figure 1 a power module 1 with batteries, a signal reception module 2 with an antenna 4 and a receiver 5, a drive module 3 of a latch, a remote control device 7, a decoder is illustrated 8, an electromagnetic device 19, a solenoid 6, a first integrated circuit 1 1, a reference diode 10, a second integrated circuit 12, a first connector 13, a third integrated circuit 18, a transistor 14, terminals 15,16 and a diode 17.

Figure 2 shows the remote control device 7 with a fourth integrated circuit 20, an antenna 21 and power supplies 22 of the remote control device.

Thus, in a specific embodiment, the device for actuating strikes of the present invention would work as follows.

The device consists basically of three modules, a power module 1 with batteries, which is part of the device that supplies the necessary power for the device to work.

Likewise, the supply module 1 comprises the first integrated circuit 1 1 that maintains a complete supply cycle of the receiver 5 by means of a low frequency oscillation, and the second integrated circuit 12 that controls the supply voltage and the reference diode 10. This reference diode 10 detects the value of the supply voltage.

It also has a signal reception module 2. This module 2 comprises in this embodiment an antenna 4, although it could have more than one. This module also comprises at least one receiver 5, in this embodiment it is a receiver, which receives the signal from the antenna 4.

Finally, the third of the modules is the actuator module 3 of the latch that is activated by an instruction sent by remote control device 7 and subsequently accepted by the decoder 8 that authorizes the latch (not shown) to be operated. or close the door or window.

One of the greatest advantages of the present invention is the fact that the battery consumption of the device is saved.

This is achieved because the duty cycle is established for a predetermined period, for example 1/3 of a second, that is to say that the first integrated circuit 1 1 is activated every 1/3 of a second, so there is a first saving of 2 / 3 battery consumption.

In addition, the activity time of said work cycle is equal to or less than the aforementioned predetermined period, that is, it can be programmed that the activity time per cycle is also shorter, such that for example if it were less than 1/8 of second per cycle, this rebate should be added to 1/3 of the cycle.

The approximate savings would be of the order of doubling at least the useful life of the batteries, thinking of large communities of neighbors with great traffic of people. In the case of individual dwellings, the Savings may not have to change batteries until several years have elapsed.

When the remote control device 7 sends a signal to the antenna 4 it transfers the signal to the receiver 5, by means of the first connector 13.

This signal in this embodiment is sent to the third integrated circuit 18 via the resistor 9, and from there to the decoder 8 that interprets the signal, sending said information to the third integrated circuit 18 that authorizes the signal or not.

If the signal is accepted, an order is sent to the drive module 3 that operates the electromagnetic device 19, for example a solenoid, which acts on the latch.

The electromagnetic device 19 comprises a first transistor

14 which receives the order of the third integrated circuit 18, which drives a solenoid 6 connected to terminals 15,16 and a diode 17 connected in parallel with the external coil to protect the transistor 14 against the impulses of reverse voltage by activation of solenoid 6.

Optionally, there is the possibility that the device comprises a second transistor (not illustrated in the drawings) that at the moment when the decoder 8 detects a valid instruction, said second transistor gives continuous voltage stopping the oscillation.

In order to improve the performance of the antenna, especially if the device is in a glass door, the antenna 5 will be arranged on one side of the container, thus avoiding any effect that prevents the propagation of the waves radio frequency, such as a Faraday box.

The remote control device 7 (Figure 2) has been designed so that any power supply 22 can be applied thereon.

This allows it to be placed, for example, on a wall, connected to the mains, or be a remote control with batteries. That is, it enables the versatility and adaptability of the remote control device 7. To do this, it requires a fourth integrated circuit 20 with a stabilizer that increases the radiated power of the stationary control devices by increasing the voltage on it, that is, it allows the range of the remote control device 7 to be calibrated.

Also, in this embodiment, it has been configured that the antenna 21 of the remote control device 7 be spiraled because it has been found that it allows a greater range with low manufacturing costs. Obviously this does not limit the use of another type of antenna 21 that, due to specific needs, can be used.

It is understood that the circuits shown are examples of their manufacture, that while maintaining the technical characteristics mentioned in the claims, others can be configured by adding or removing resistors, capacitors, diodes, etc., by changing the drawing of the scheme, but whose behavior It would be the one explained above.

The present invention describes a new device for the operation of strikes. The examples mentioned herein are not limiting of the present invention, therefore it may have different applications and / or adaptations, all of them within the scope of the following claims.
