Description:
LOCK CONTROL MECHANISM

TECHNICAL FIELD

The invention relates to a lock control comprising a drive element associated with the lock mechanism of a door, and a driver that drives the said drive element.

PRIOR ART

The communication systems wherein light is used as information carrier have been of great interest recently. Emitting the light waves in the earth atmosphere is difficult and inconvenient. Therefore, researches are conducted in today's various leading development laboratories regarding the systems wherein glass or plastic fiber cables are used to "contain" a light wave, and to send this wave from a source to a destination. The communication systems carrying information through a guided fiber optic are named as fiber optic systems. Li-Fi used the light as carrier instead of the radio waves used in Wi- Fi. Light is used as data carrier thanks to this technology that has been introduced for the first time at the Consumer Electronics Exhibition in Las Vegas in 2012. The VLC (visible light communication) concept has been introduced before the Li-Fi concept, and it has been shown that connections could be provided via visible light.

Door and lock opening mechanisms have started to develop with the development of the electronic systems and remote control systems. More secure systems such as proximity, remote control, RFID, NFC biometric data readers, have been started to be used instead of the metal keys and manual door opening systems incorporating the widely known physical coding details, so as to activate the lock systems. The said electronic lock control systems receive from the user the commands by the user without a metal key, and inquire them. If the command transmitted by the user to the system is a command acceptable by the system, a motor is activated and the lock mechanism is opened. The phase of transmission of the commands by the user to the lock mechanism is the most important phase of the lock system especially when considered in terms of security. Therefore, there are many different ways used in the prior art for transmission of the commands to the lock system.

The application no. EP2284803 mentions a system wherein the key is sent to the lock mechanism with acoustic code. In such systems, the user needs to be close to the lock system. Remote control cannot be performed. Moreover, since the electronic components of the lock systems are outside the door, they are vulnerable to attacks and manipulation.

In conclusion, all the problems mentioned above have entailed an innovation in the respective technical field.

This detailed description explains the subject of the invention by examples that will not constitute any limiting effect and are merely for better understanding of the subject.

The lock control mechanism (100) that is subject of the invention essentially ensures unlocking of a door (400) in case it detected that a signal in suitable pattern is received form a control device (500).

Referring to Fig.1, the lock control mechanism (100) comprises a signal detector (110). The signal detector (110) may comprise a microphone in a possible embodiment. The signal detector may comprise a photodiode in another possible embodiment. The signal detector (110) generates signal according to the light or sound falling thereon. In a possible embodiment, a first signal detector (110a) and a second signal detector (110b) are provided such that one is positioned on a side of the door (400) and the other is positioned on the other side thereof.

The Signal detector (110) is connected with a mixer (130). A processor unit (120) evaluates the signal it receives from the mixer. The processor unit may be a microprocessor. The said processor unit (120) is associated with a driver (140) so that a drive element (150) applies drive to the door (400). The drive element (150) is a motor.

The control device (500) comprises a signal emitter (510). The said signal emitter (510) is arranged such that it is controlled by the processor of the control device (500) and will emit signal in the predetermined pattern. In a possible embodiment, the signal emitter (510) may be a speaker arranged to emit sound. In another possible embodiment, the signal emitter (510) is arranged to emit light. In such embodiment, the signal emitter (510) may contain LEDs or LED arrays.

In an exemplary embodiment, the control device (500) may be a mobile phone, tablet computer, etc. The signal emitter in this exemplary embodiment is the display screen of the mobile phone or tablet computer. The control device (500) is in the form of a tablet, and a flat face thereof is defined as front face (502), and the face which is opposite to the front face (502) is defined as rear face (504). The control device (500) may comprise a user interface (540) allowing command entry by the user for initiation of the signal emission operation by the user. The user interface (540) is positioned on the front face (502).

The information related to the signal to be emitted by the signal emitter (510) may be stored in a memory unit (not shown in the figure). The processor of the control device (500) ensures that the signal emitter emits signal according to this information. In case the signal emitter (510) is a light source, the signal emitting operation may be in the form of sending the light intermittently such that it expresses a code or in different wavelengths such that it expresses a code. In other words, the signal emitter (510) may express a code by emitting different colors. In a possible embodiment where the signal emitter (510) is a microphone, a particular sound pattern can be sent, or the code can be expressed by sending and stopping a sound signal at a fixed magnitude. In case the signal emitter (510) is a light emitter, the emitted light may be within the visible spectrum or outside the visible spectrum. In case the signal emitter (510) is a speaker, the emitted sound may be at a frequency not perceivable by human ear or at an audible frequency.

The control device (500) can receive the code serving to activate the lock control mechanism (100) from a server (620). The said code is generated by the server (620), and may contain the unique ID expressing the door associated with the lock control mechanism (100), the time stamp, may be in hashed formed. The said code is generated with Time-Based One-Time Password (TOTP) algorithm.

In a possible embodiment as in Fig.2, the lock control mechanism (100) may comprise a remote control device (200). The remote control device (200) is preferably placed such that it faces the signal detector (110). The remote control device (510) comprises a communication interface (210), a second processor unit (220), and a second signal emitter (230). The communication interface (210) has been arranged such that it receives data wirelessly. The communication interface (210) can receive data through GSM/GPRS/Wi-Fi protocols. The remote control device (200) may also contain a power supply (240). A power supply (240) may be a battery. The remote control device (200) ensures that the code it receives from the communication interface (210) is transmitted from the second signal emitter (230). The data received by the communication interface (210) are in BCD (binary-coded decimal) form. This data is converted into light or sound patterns by the second processor unit (220), and these patterns are obtained in light or sound form by the second signal emitter (230).

The lock control mechanism (100) is also associated with a power supply (not shown in the figure) like battery. The lock control mechanism (100) may comprise a warning element like LED, which indicates the level of the power supply (not shown in the figure).

Referring to Fig.3, the signal detector (110) is positioned in a body (160) that is positioned on the door (400). The said body (160) comprises a control device housing (161). The control device housing (160) has a cross section in U form.

Referring to Fig.4, the control device housing (161) is dimensioned such that it takes in part of the control device (500). In this exemplary embodiment, the control device housing (161) is shaped such that a flat face of the control device (500) in plate form faces the ground, and it allows taking in the device in the position parallel to the ground. In this exemplary embodiment, the control device housing (161) comprises a support surface (162) touching the face of the control device (500) that faces the ground (rear face) while the control device (500) is inside it.

Referring to Fig.5 and Fig.6, the control device housing (161) comprises at least one resting protrusion (163) touching the front face (502) of the control device (500) while the control device (500) is inside it. In this exemplary embodiment, the resting protrusion (163) is provided as two pieces such that they define a signal transmission channel (164) in between. The signal detector (110) is positioned between the two resting protrusions (163), such that the control device (500) faces the signal emitter (510) while it is inside the housing. The signal exiting from the signal emitter (510) passes through the signal transmission channel (164) and reaches the signal detector (110).

The resting protrusions (163) and support surface (162) also ensure that the control device (500) stands steady in the control device housing (161). Since only part of the control device (500) enters the housing and its front face (502) faces up, it allows use of the control device (500) by the user during the unlocking operation.

A presence detector (168) is positioned on the body (160) which ensures querying whether the control device (500) is in the control device housing (161). The said presence detector (168) may be connected with the processor unit (120). The presence detector (168) may be IR detector, and generates signal according to the IR light rays emitted by the objects entering its range, and sends them to the processor unit (120). Thus, it can be ensured that the lock control mechanism (100) runs in power saving mode while the control device (500) is not in the control device housing (161).

Below is how the invention detailed above runs: The user places the control device (500) in the control device housing (161) such that the signal emitter (510) faces the signal detector (110). Placement of the control device (500) is detected by the presence detector (168), and lock control mechanism (100) is made ready. The signal emitter (510) is activated through the user interface (540). The signal emitter (510) emits sound signal or light in the predetermined pattern. The signal detector (110) detects the emitted signal, and sends a signal expressing this to the mixer (130). The mixer (130) transmits this signal to the processor unit (120). The processor unit runs the driver (140) in case it detects that the received signal expresses a predetermined code or is in a predetermined pattern. The driver (140) drives a drive element (150). The drive element (150) in turn opens the door lock or the door (400) which it is associated with. During signal sending, the user can continue using the use interface (540).

In one of the possible embodiments, the user can send code to the communication interface (210) of the remote control device (200) through a communication network (610) by using a client device (600) such as a mobile device, a computer, etc. The communication interface (210) transfers this code to the second processor unit (220), and the second processor unit (220) ensures that the second signal emitter (230) emits signal expressing the code. Thus, it is ensured that the user opens the door (400) or door lock remotely.

The code to be authenticated by the lock control mechanism (100) may have been formed through one-time password method comprising 3-Des. 3-DES Banking system is used in serious security programs, electronic payment systems (online shopping with credit card, etc.). In case the invention is used in defense industry, AES (Advanced Encryption Standard) that has a more developed algorithm can be used for advanced lock protection systems. A software comprising the initial key value, generating one-time light or sound patterned password, can be installed on the control device (500) of the individual. Thanks to this software, the signal emitter (510) of the control device (500) is activated through the user interface (540), and light or sound is emitted such that they express the codes.

One of the signal detectors (110) is positioned outside the door, and other electronic components can be positioned inside the door (400). Thus, it is made difficult for ill- intentioned people to intervene in the lock control mechanism (100).

The protection scope of the invention is specified in the claims annexed hereto, and it may in no way be limited to the disclosures made for illustrative purposes in this detailed description. Because, it is evident that a person skilled in the art can present similar embodiments in the light of the foregoing without deviating from the main theme of the invention.
