Security locking system for subsequent installation on house and apartment doors

Application: The security locking system is intended to serve as an additional barrier

can be retrofitted from the inside of house and apartment doors to make it impossible for burglars who overcome the existing locking system from the outside to open the door.

State of the art: House and apartment doors are mainly locked by box locks, which are built into the door leaf, using latches and sliders. The locking mechanism is achieved using normal keys or security keys (profile cylinders). The advantage is that they are easy to use and relatively secure against unauthorized opening. The disadvantage is that the locking cylinders can be sheared off within a minute using a tool available on the market (Ziehfix from Wendt), and the door can then be opened.

Criticism of the standard technology: Unauthorized persons are able to open a lock from the outside using special tools (pull-out or vibrator).

Task:

Solution:

The purpose of the invention is to ensure that the door can only be opened by authorized persons.

A sturdy steel housing, similar to a box lock, mounted on the inside of the door contains a motor-

risen moving bolt, which prevents the door from opening when it is moved forwards. The bolt is moved forwards and backwards using a radio control from outside or from inside. A two-coloured red or green optical display, preferably a two-coloured LED, which is led to the outside, shows the current position of the bolt. The radio signal is sent to the receiver in coded form in order to achieve a very high number (greater than 50,000) of different codes. Once the bolt has reached its respective end position (forward or backwards), the motor current is switched off. An emergency opening from inside is possible by manually moving the bolt.

Achievable security against unauthorized opening of the door is provided by installing the radio lock.

Description of an example:

The radio lock shown in Fig. 1 consists of a box-shaped housing 1 closed on four sides, in which a movable lock 2 can be moved back and forth by a gear motor 5 using a rack 3 and a pinion 4. The movement of the lock is switched off in the end positions via the microswitches 6 and 7. At the same time, the microswitches switch the LED 8 to red or green, and the motor is controlled by the electronics 10 via a 3-core cable 9. This receives a coded signal from the hand-held transmitter to open or close. The radio lock is screwed to the masonry using screws approx. 15 cm long. Fig. 2 shows how it is attached to the door.
