Background of the Invention

Nowadays, various locking systems are used for locking doors or keeping them closed. While there are doors including locks which cannot be broken by thieves, there are also doors which are locked or opened by cards, remote control devices or fingerprints instead of keys. There are also electric motor-driven full automatic systems among these.
Among the examples used in the prior art, the automatic door closer (door hydraulics) is a mechanism, which provides automatic and crash-free closing of the door to which it is mounted, and it is commonly used in building doors. Besides building hydraulics, office, workplace etc. hydraulic application can also be made and it can be applied to all kinds of doors such as building doors, steel doors, furniture and wooden doors, glass doors etc.
Other examples found in the known status of the art are given below.
In the European patent no EP1747339B1 , a sliding door system having a drive device placed at the upper transom is disclosed. The invention relates to a sliding door system, and this system comprises a drive device at least for a door leaf and an electromechanical actuation device for locking the door leaf in relation to the upper transom. The system also comprises endless traction means guided via a driven pulley of the drive device and tension-resistantly connected to the door leaf. The invention is characterized in that, the driven pulley of the drive device has locking elements located at a flange adjacent to its housing, and the locking elements which are adjustable at the locking elements of the flange are supported at the housing and they adjustable at the locking elements of the flange.
In the utility model no TR 2004/03488, a door locking system is disclosed, which is electric motor driven and which is full automatic-electronic opened and closed. The invention particularly relates to an automatic door lock system which can be adapted and used in all locks used in wooden, glass, aluminium, and iron doors, and it comprises a motor block which opens and/or closes the lock, to which it is adapted, according to a command taken from the electronic control unit, an accumulator block which provides the energy to open and/or close the door in case of power cut, an on-off block which gives the command to open and/or close the motor block according to the internal, external, and sensor provided signals, a plug contact which conveys electricity to the motor block, and a door sensor which determines the situation of the door and sends the signals of this situation to the electronic control unit.
The utility model no TR 2008/03041 relates to an automatic door system, which automatically opens and/or closes the sliding doors that are used manually in commercial vehicles. Automatic opening and closing of the manually used sliding doors in the commercial vehicles are provided with the mechanic part comprising a gear belt (time belt, trigger belt) which is driven by a direct current electric motor and in which exchange ratios are provided via reducer, a belt gear, belt pulleys, a tensioner, a door puller system and lock bolt puller system; and with the electronic control system by which the controls are made for providing the desired engine revolutions, starting up and aborting the operation of the engines, providing the door stay in the desired position, providing the door with the desired speed while opening and closing, pulling and pushing of the door, preventing crushing in the doorway, providing audio and light warnings, providing opening and closing of the door be controlled by the driver and also by remote control device, providing closure of the door by application of opening operation to the door opening handle when it is open and vice versa.

Detailed Description of the Invention

In this detailed description, the preferred embodiments of the lock system (1), which is the subject of the invention, will only be disclosed as an example for better understanding of the subject, and will not form any limiting effect.
In Figure-1, the top view of the lock system (1), which is the subject of the invention, is given while the door (2) is in closed position. The door (2) mounted on the wall (3) via the hinge (2.2) seems to be closed via the lock bolt (2.1) on the other side. The said lock system (1) comprises a piston (7), which is connected to the door (2) via a juncture point (11) placed at the backside of the door (2), and which is connected to the wall (3) that is in crosswise position with the door (2), via another juncture point (11). Fluid (8) material is found inside the said piston (7), and due to the motion of the movable part (7.1) inside the piston (7) and since this fluid (8) can not be compacted, it goes between the front and rear chambers (7.3, 7.4) of the piston (7) by passing through the pipe (10).
In Figure-2, the top view of the lock system (1), which is the subject of the invention, is given while the door (2) is in open position. Under normal conditions, a person, who opens the lock bolt (2.1) by holding the door (2) from the handle (2.3), pushes the door (2) towards inside in order to enter. This pushing movement causes the starting handle (7.2) connected to the door (2) via a juncture point (11) placed at the backside of the door (2), and the movable part (7.1) connected this starting handle, be pushed ahead. Therefore, the fluid (8) found inside the piston (7) moves from the rear chamber (7.4) to the front chamber (7.3) by passing through the pipe (10). In order to provide this movement, the valve (9) placed on the pipe (10) has to be left open.
In Figure-3, the schematic view of the remote control device (4) of the lock system (1), which is the subject of the invention, is given. The ON (13.1) and OFF (13.2) modes of the control and encryption unit (13) is shown here. In cases where opening of the door (2) is not wanted due to security or other reasons, the lock system (1) works as described below. Code is sent to the control unit (5) using the remote control device (4), which operates via radio frequency (RF). The microcontroller (5.1) located in the said control unit (5) decodes the code coming from the remote control device (4) and received via RF receiver module (5.3), and if the code is correct, then transmits it to the motor driver and position detector (5.2).
In Figure-4, the schematic view disclosing the operation of the control unit (5) of the lock system (1), which is the subject of the invention, is given. The information transmitted to the motor and the position detector (5.2) is then transmitted to the motor (6) in order to make it close the valve (9). When the valve (9) is in closed position, the fluid (8) located inside the piston (7) is prevented from moving between the chambers (7.3, 7.4). In this case, the movable part (7.1) and the starting handle (7.2) connected to this part are completely fixed, and thus the person who tries to open the door (2) can not push the door (2). Since the fluid (8) found inside the piston (7) can not be compressed due to the laws of physics, the door (2) can not be opened by pushing and thus the desired security is provided.
The invention is a lock system (1) developed for providing security, and it is characterized in that; it comprises:

RF receiver module (5.3) receiving the code sent by the remote control device (4); control unit (5) managing all the system and including a microcontroller (5.1) for decoding the said code, a motor driver driving the motor/engine (6), and a position detector (5.2),
remote control device (4) which sends encoded data to the said control unit (5) via radio frequencies and thus orientates it,
hydraulic piston (7) which comprises a fluid (8) located in its body and can replace between the front chamber (7.3) and the rear chamber (7.4),
pipe (10) placed on the said hydraulic piston (7) and connects the front chamber (7.3) and the rear chamber (7.4) to provide replacing of the fluid (8),
valve (9) placed on the said pipe (10) and can prevent passage of fluid (8) according to the commands (5) coming to the engine (6) from the control unit (5) and thus can prevent opening of the door (2) by being pushed, and
engine (6) connected with the valve (9) and the control unit (5) in order to actuate the valve (9).

The said lock system (1) also comprises a feed and accumulator charging unit (12) in order to provide the required energy for operation of the system (1) and in order to charge the accumulator.
The protection scope of this application has been specified under claims and cannot be limited to the descriptions only given as sampling above. It is obvious that a person skilled in the related art can apply the innovation disclosed by this invention into similar purposed other areas by means of changing the parts in form and using similar structures. Therefore, it is also clear that such embodiments lack of novelty and inventive step criteria.
