Description

DESCRIPTION

Door lock system. Scope and prior art

The present invention generally relates to a door lock system with an electronic key.

Everyone knows the current problem, derived from the need to carry, for example even in separate key chains, a large number of keys, to operate the locks to enter the home, the office, open or close files, garage doors, etc. , and even access cards that the user keeps in his wallet for opening or closing doors, cabinets, filing cabinets, etc., and that are a real hindrance to the volume occupied as well as the search for the appropriate key or card when It is necessary to open a certain lock.

Currently, door lock systems are known with an electronic key in the form of a card that has a magnetic registration band where the opening code of the lock is recorded and incorporating a card reader that is intended to unlock, for example, the handle of the lock, but in these systems each card must be recorded with a single code for the opening of a single door so that for each lock an individual card must be used, so that the problem described is not solved either. Summary of the invention

Starting from the prior art described above, the invention aims to develop a lock system that avoids the need to carry a large number of keys in which the user can accumulate in a single electronic key the codes necessary for opening of as many doors as necessary.

This objective is achieved through the characteristics indicated in claim 1. Other advantages and additional objectives are achieved through the characteristics indicated in the dependent claims.

The door lock system comprises:

an electronic key with opening code storage means;

a lock with a rotating element that can be unlocked by means of an opening relay to actuate a latch of said lock;

which according to the invention is characterized in that:

The rotating element is intended to drive a dynamo that transforms its 5-turn movement into electric voltage for charging a battery that supplies working voltage to the opening relay and allowing the latch to be activated;

- a CPU with an associated memory is provided for storing lock opening codes and which serves to govern the operation of the opening relay; - a USB port associated with the CPU is mounted on the lock shield; Y

The electronic key is provided with a portion that includes mass storage media 5type USB where at least one lock opening code is stored and that when inserted into the USB port and are read and compared with the authorized codes stored in the memory of the CPU and that in case of coincidence with a code of opening lOau toriz ado, said CPU makes operative the opening relay so that when activating the rotating element generating the supply voltage for said opening relay and releasing the latch of the lock that can then be operated to open the door.

According to an additional feature of the invention, it is advantageous to arrange the lock with an opening handle for actuation of its latch, here provided as a slip and whose handle is coupled to a gear that forms the rotating element.

In accordance with a further feature of the invention, the rotating element is provided as a key cylinder that includes at least one portion of the cylinder on which a USB port is mounted to rotate with said portion of the cylinder, and coaxially mounted the portion from bowler a pair of gears and a first pinion that meshes with a second pinion fixed to the shaft of the dynamo; and a clutch gear is provided to engage with the pair of

30 gears when the opening relay powered by the battery associated with the dynamo is driven. In accordance with another additional feature of the invention, it is advantageous to incorporate in the lock shield an activation sensor located below the USB port for the activation of the CPU 5 and a system clock implemented by said CPU.

Also according to an additional feature of the invention, it is advantageous to have an external LED located near the USB port to illuminate it and facilitate the insertion of the electronic key into the USB port of the lock when there are reduced lighting conditions.

In addition to another additional feature of the invention, it is an advantage when the lock is provided with accumulation batteries of

15energy for CPU power.

Even in accordance with another additional feature of the invention, it is an advantage when the lock includes a safety lock which is operated manually with a handle accessible through the shield of said lock.

As the experts will appreciate when the system includes an internal memory and a reliable and secure USB port easily available in the market, the electronic key can be supplied as a "pen-drive" 5 and can store in its external memory so much code information opening locks as necessary and allows to carry a single key for all locks that are owned or needed to be handled. On the other hand through this system the

The electronic key can be loaded with data on opening codes of one or more locks using a user's PC or configured as a key master, using the USB port of the lock as a means of communication, to add or remove the code information on the mechanism of opening the locks in any other lock, and whose information can be updated or changed with an appropriate computer program.

As according to the invention, the electronic key is configured as a conventional key shape has an exterior appearance that is acceptable to the user, which generally rejects the use of the opening cards.

As the system incorporates a CPU, once the verification of the performance codes of the CPU is formalized with those of the corresponding file in the

1511ave or verification that it has the opening permit, at that moment it will be validated and allow the door to open, the processor of the lock, can record the information of the moment of opening the door with 0the data of what key and at what times or times it has been used with the help of the CPU system clock.

As indicated above, the CPU installed inside the lock allows the access codes to certain locks to be transferred to other keys of different users and, if necessary, for a defined or limited time.

A system according to the aforementioned 30 provides the following advantages: - Due to its possibility of mass production and economical materials of usual use, the cost of the product is reduced.

The possibility of adapting a conventional lock, since the necessary elements can be installed next to a cylinder with a USB port, on either side of a door equipped with the lock.

- Being an element with built-in memory, it is not necessary to carry a keychain full of keys, with the lone only enough to open any door of passage or elements with lock.

By owning the lock a CPU, you can perform a check to record at every moment what key has been used and at what time.

15 - Thanks to the CPU of the lock itself and the electronic master key, it is not necessary to move to a computer, in order to pass information on a new key and this is practicable.

- Similarly, by means of the memory of the lock, several keys can be canceled or activated, for a limited time.

As the electronic key incorporates a USB type removable information storage device, commonly known as a "pen drive", it can be perfectly used additionally to store and transport other digital files in addition to those related to the codes for opening locks.
