Description

DESCRIPTION

Alarmed door lock The Related Art

The invention relates to alarmed door lock in the size of mechanic ordinary door lock, which may be armed/disarmed according to the position of lock deadbolt and be used in mechanical doors (wooden, steel, aluminium, plastic etc.) without any modification on the door.

The Prior Art

The present mechanical door locks provide security of the door where they are mounted with mechanical lock mechanism and does not contain alarm system in their body. To protect this type of door with an alarm system, either an additional system or additional one/more than one sensor is required to be mounted on the door. This may not only increase mounting and labor costs but also may distort aesthetic of the door. Current electronic alarm locks require a control unit such as password, card, finger print etc. in order to arm and disarm the alarm.

In current shock/impact detecting electronic alarm locks, shock/impact detecting sensitivity adjustments may be conducted by removing the device or through a control unit such as keypad etc.

Also in current shock/impact detecting electronic alarm locks, while the device detects unwanted opening of door and send alarm but when no alarm is wanted in case of shock/impact (that is when desired to deactivate shock/impact sensor while alarm is armed, which is a feature mostly needed in places where pets are owned), such operation may be provided by control unit such as an external keypad, remote controller etc.

As a result, due to above described disadvantages and inadequacy of existing solutions it has been necessary to make development in the related art. Purpose of the Invention

The invention has been developed while being inspired by the current situations, aims to eliminate the disadvantages mentioned above.

Main purpose of the invention is to provide an alarmed door lock by integrating alarm system to mechanic door locks and may be used instead of ordinary door locks. Alarmed door lock is mounted in the same manner as ordinary door locks. Thus no additional mounting labor cost is needed and also aesthetic of the door is not distorted since no senor or device is mounted on the visible part of the door.

Another purpose of the invention is to arm and disarm the alarm with the rotation of the cylinder which is used in mechanic door locks. Thus in order to arm and disarm the alarm, an additional control unit is not needed either. In addition, the invention is also capable of being controlled through an additional control unit such as keypad, card reader etc.

In the alarmed door lock disclosed under this invention, shock/impact sensitivity adjustment is provided by the rotation of the cylinder. Similarly, when the alarm is armed, the shock/impact sensor may be deactivated by the same cylinder as well. Therefore, no additional control unit is needed for such operations. In addition, the device is also eligible to adjust such settings by additional control unit such as keypad, card reader etc. In order to achieve the purposes mentioned above, the invention comprises the followings:

• Mechanical switch or magnetic field sensor located on/in the lock body which detects opening of the door and deadbolt's motion,

• shock/impact sensor located in the lock body which detects shock/impact on the door,

• Microcontroller where the data obtained from shock/impact sensor is delivered and which is located on/in the lock body and activates the alarm by triggering the sound unit which is also located on/in the lock body in case of the data obtained from shock/impact sensor is higher than the threshold value. The structural and characteristics features of the invention and all advantages may be understood better in detailed descriptions with the figures given below and with reference to the figures, and therefore, the assessment should be made taking into account said figures and detailed explanations.

Arming the alarm

When the alarmed door lock (A) is fully locked from outside or inside by the lock cylinder (6) with key or handle, the lock deadbolt (5) go outside of the lock. This action is detected by the microcontroller inside the alarmed door lock (A) by the help of micro- switch or the magnetic field sensor (3) located in the inner section of the lock, and thus the alarm is armed. In case of shock/impact on the door when alarm is armed, the shock/impact sensor (7) detects the shock/impact and sends information to microcontroller. In case of magnitude of the shock/impact is over the threshold value of the shock/impact recorded in the microcontroller, the sound unit (4) is activated to alarm. If the door is opened without being unlocked (ill-intended persons may conducts such actions by using of lever jack etc.), the magnetic field sensor (3) sends information/warning to the microcontroller as it gets away from the magnet located on the door case. The microcontroller triggers the sound unit (4) to alarm.

Disarming the alarm

In case of alarm is armed (when the lock deadbolt (5) are outside of the lock), when the door is opened from outside or inside by key or handle by the lock cylinder (6), this motion is detected by the microcontroller by the help of micro-switch or the magnetic field sensor (3) located in inner part of the lock body (1), and the alarm is disarmed.

Setting Shock/Impact Sensitivity of the Alarm

The alarmed door lock (A) automatically goes into shock/impact setting mode when it is completely locked from inside or outside by the lock cylinder (6) through key or thumb turn when the door wing is in open position. In this case, upon the command received from microprocessor, the sound unit (4) starts to give one warning sound of "beep" (when the shock/impact setting is sensitive), two warning sounds of "beep beep" (when the shock/impact setting is normal ), and three warning sounds of "beep beep beep" (when the shock/impact setting is less-sensitive). In such case, the alarmed door lock (A) shock/impact sensitivity is set to the position in which the user unlocks the lock. Also as explained above this operation is performed as follows.

❖ After giving one warning tone, if the person unlocks the lock, decreasing of said threshold value via microprocessor,

❖ After giving two warning tones, if the person unlocks the lock, adjustment of said threshold value to normal value via microprocessor,

❖ If the person unlocks the lock after three warning tones, increasing the threshold value via the microprocessor. Deactivation of the shock/impact sensor (7) when alarm is armed

If the alarm is disarmed and armed by key or handle within 5 seconds after arming of the alarm, the microprocessor arms the alarm in a way ignoring the signals to be sent by the shock/impact sensor (7).
