ELECTRIC LOCK FOR DOORS DESCRIPTION OBJECT OF THE INVENTION

The present invention relates to an electric strike for doors that can be used on any door with access control, for example in hotel rooms and tourist apartments, schools, clinics of any kind, offices ..., which allows them to be operated at through portable devices.

BACKGROUND OF THE INVENTION

Currently, electric locks for doors with access control are known. For example, in hotel rooms and tourist apartments, they usually have a cardholder for enabling the lock with a card, which is also subsequently inserted into another internal cardholder of the room to also enable the supply of electric light.

These locks incorporate motorized interior mechanisms in most cases, to enable unlocking the opening of the lock. The power supply of these locks is carried out by batteries or batteries, since they are incorporated into the mobile door leaf.

An evolution of these locks implements a communications interface via radio waves, usually NFC®, which by means of relays manage to activate the motorized interior mechanisms to enable the opening of the lock. This allows to dispense with the traditional opening card and use the user's mobile device for it; but it has the disadvantage that they increase the consumption of the battery, since the radio interface is permanently in signal search mode, it is also not compatible with traditional systems such as cards or keys. This dramatically decreases the autonomy of the batteries, with the additional disadvantage that if they are discharged, the lock is deconfigured and must be reconfigured in situ. On the other hand, the replacement of all existing cardholder locks with locks with radio interface technology will be even more expensive,

and with the disadvantage that there is a certain age of the population that prefers the traditional means of opening a card or key and / or who are not familiar with the use of the new technologies. In addition, the NFC® technology does not have large scopes nor does it allow data encryption.

On the other hand, electric drive locks are known for automatic door entry doors, which comprise a releasable retaining element of a lock (slip or lock) of the lock, and actuation means of said releasable retaining element. The releasable element is normally a collapsible sector according to an axis parallel to the slip, and that by means of internal cams, it remains locked until by feeding from the outside of a coil said cams are retracted unlocking the movement of the collapsible sector, which also has a spring that recovers the closing position, so that once the coil supply has been interrupted and the door closed, it is again blocking the opening. They can carry additional elements, such as opening retarders, mechanical unlocks, etc. The problem of these locks is that they are not adapted to their use through new technologies, so that the opening is done by means of an internal push-button, so it is not a valid operation for hotel rooms or tourist apartments, where there are no stable stays inside from the same.

DESCRIPTION OF THE INVENTION

The electric door locks of the invention have a configuration that solves the problems described that directly hinder or prevent the implementation of opening means in doors by means of new technologies for use with portable devices. In addition, its use represents a saving, since it reduces the use of elements that can be damaged or lost, such as access cards, widely used in the case of hotels, tourist apartments, offices, etc.

Indeed, on the one hand it solves the problem of electricity consumption, since the locks can be fed from an electrical network of the farm where the door is with access control, as cables can be passed through the door frame; and it can be adapted to any existing lock, even if it is not electric since the one that will open and close is going to be the lock, not the lock latch, so you don't need to change the existing lock.

Therefore, the strike is of the type that comprises a releasable retention element of a lock (slip or lock) of the lock, and means for actuating said releasable retention element, and which according to the invention additionally comprises:

-a module of communication by radiofrequency Bluetooth® to receive the configuration of keys for the locksmith as! as of the door opening commands sent from a user terminal,

-a first storage memory of the configured key,

-a second memory to store information of the openings and closures made with their respective schedules,

-a processor comparing the keys stored in the first memory with the keys issued from the user terminal,

-at least, a feeder of the actuation means of the releasable retention element, controlled by the key comparison processor, for example a transistor, operational amplifier, etc, and

-a power supply for the communication module, memories, key comparison processor and feeder of the drive means of the releasable retention element.

With this configuration it is allowed:

1 ° feed the strike from the local electricity grid. There are therefore no spent batteries, costs associated with them or deconfigurations in case of battery depletion.

2 ° configure the locks from the access control centralization, thanks to the scope of Bluetooth® technology

3 ° ensure security, thanks to the encryption that supports Bluetooth® technology, which prevents the interception of legitimate uses and / or configurations by malicious third parties.

For the operation of the locksmith, an application must be previously installed in the mobile user terminal (smartphone, tablet, laptop, etc.). Said application is activated through a code that is sent to the access control centralization preferably from a remote key server via a tcp / lp connection and, once the code is admitted, the application is activated for a certain lock during a weather

determined, for example in hotels or tourist apartments during the stay of a

client, or in laboratories, offices, etc., during the professional relationship of the authorized person. Said dedicated server is therefore the one that controls the openings and closures of doors, giving access through the keys and preventing access when the time has elapsed after which has authorization. This authorization is requested from the server through files by the locksmith operation manager.

The locksmith is registered in the remote server as belonging to a specific administrator, and this through a desktop application (software) installed on a PC for example located in the access centralization of the farm will request authorization to each user to through the application installed on your mobile device on certain dates or permanently. When opening the door, the user will manage the application of his mobile device to unlock the lock, which will issue the key configured particularly for it. The key will be compared by the processor with the key previously entered in the first key storage memory, and in case of coincidence the processor will send an opening signal to the feeder of the actuation means of the releasable retention element, which will feed said means to unlock the releasable retention element, allowing the door to open. Once the door closes again, the locksmith will have recovered the initial closing position, and only the door can be opened by repeating the previous steps, or acting directly on the lock through its knob, key or card holder.
