Abstract

Door locking knobs on vehicle doors are used, the top part of which knobs are of transparent design, having multi-colour LEDs arranged on them which indicate the release of the door by one colour. Delay times before closing and alarms are indicated by flashing. Various necessary switching stages are explained.

Description

A large number of automobiles are stolen every year. Various types of securing devices are used to secure the vehicles systems have been constructed. Almost all of these plants are as acoustic warning systems that close by triggered by contacts. As a rule, the Door contacts on the vehicle doors shared, the priority for switching the vehicle interior lighting on and off serve.

A switching path changeover - usually with a key switch ensures that the alarm device is "armed". Mostly the alarm is signaled by a horn signal, the duration of which is restricted by law.

An audible alarm cannot last longer hold, because it disturbs too many people, especially at night time.

An alarm by light signals is mostly not used because as a result, the vehicle battery is overloaded.

The invention described below uses light signals, however, these are set to use less power. Their application is not yet known in this form.

Most vehicle doors are on the lower door windows near the door locks, door latch knobs attached. The door latch knobs, usually designed as a round bar, are depressed to lock the vehicle doors, causing the Doors are locked. The doors can be reopened only done with a key.

The present application for industrial property rights provides for the rod-shaped door latch knobs at their end in a light-transparent form to execute. Inside the light-transparent part is a light-emitting semiconductor, a so-called LED, arranged.  

It is preferable to use a 2 or multi-colored light Use LED in which at least 2 colors by current direction reversal can be generated.

This 2-color LED, preferably in the colors "green" and "red", is operated by an electronic control.

This controller ( 1 ) performs the following functions:

• a) When the vehicle doors are unlocked, the LED door buttons ( 10 ) light up in green.
• b) If the users leave the vehicle and press the LED door buttons ( 10 ), a flashing light of the LED door buttons ( 10 ) is initiated after the doors are closed. The flashing only takes place for a predetermined time, which should serve to close the doors without giving an early alarm.
• c) After this period, the control ( 1 ) switches to the red LED color. The door buttons ( 10 ) light up "red" and remain switched on until the doors are opened again by a bowl. The red steady light shows the locked state of the doors visible far through the glass windows and signals a vehicle secured by vehicle thieves.
• d) If a door knob ( 10 ) displayed on "red" is moved out of its position without a key, for example by external intervention, an alarm is triggered. This is indicated by flashing red. A horn signal can also be triggered.
• e) If a door button ( 10 ) is regularly operated by the vehicle user with a key, the door button color changes to "green". From this, the vehicle user recognizes that the doors have been unlocked properly, ie have been released.
• f) The electronic locking can be carried out that every attempt to press the door button without prior Key use inevitably leads to an alarm.
• g) If the vehicle user approaches his vehicle, so he already recognizes through the door panes his vehicle parked undamaged in the distance.
• h) If he flashes red, this signals that a break-in attempt has taken place on his vehicle and may even have led to success. The flashing door knobs ( 10 ) are visible from afar even from a distance. They can be seen from the living room window of the owner's apartment, from a hotel window or office window. Especially at night, when the flashing light is visibly reflected in the door windows. Patrol vehicles belonging to the police of the guard and locking companies can also be more easily recognized if they attempt to break in by blinking. Checking in guarded parking lots is also made much easier, since a red flashing is perceived more easily.
• g) While the well-known car alarm systems one The flashing can trigger a temporary horn alarm be maintained for a long time since the LEDs are only low Need electricity. You can also use the flashing signal use a radio remote control transmitter to modulate it. Via an associated remote control receiver, the Flashing modulation can be received in the hotel or office room, so that you can intervene immediately.

The electronic circuit ( 1 ) belonging to the light door buttons ( 10 ) contains a number of control logic stages ( 2 ).

A blinking stage ( 3 ) generates the blinking signal. A switching stage ( 4 ) generates the color change of the LEDs. A time level ( 5 ) controls the period between closing the doors and arming. Another logic circuit ( 6 ) executes the unlocking and locking logic when a key is pressed. Another additional level is used to trigger an alarm ( 7 ).

All associated electronics are printed on one Circuit housed. The board is installed a secured, not easily foreign person accessible place inside the vehicle instead. The circuit is powered by the vehicle battery.

The door knobs ( 10 ) consist of a transparent tip part ( 11 ) which is placed on the door knob neck ( 12 ). The 2-color LED ( 13 ) is arranged in the tip part ( 11 ). A 3-pin line connection ( 14 ) leads to the output part of the printed circuit ( 1 ). On the neck of the door knob ( 10 ) there is also a switch cam ( 15 ) which actuates a switch contact ( 16 ) when the door knob ( 10 ) is pressed in. This reports the locking status to the electronic locking logic ( 6 ).

Another, additional output ( 17 ) on the circuit board ( 1 ) is used to connect an alarm or the radio remote control transmitter ( 17 ).

The supply and Ent can lock-out logic (6) can be operated by a key switch (18) via a further contact (18).

Instead of a mechanical contact ( 18 ), unlocking contacts on a photoelectric, inductive or magnetic basis can also be used.

The transparent tip of the door knobs can also be made of light conductive plastic consist of the light reflections over glass fibers and similar from separately arranged light sources receives. Plastic pipe arrangements can also be used, which are covered with light-guiding glass fibers or strips are.

Instead of the door knobs with light-transparent tip parts door latch devices can also be used in a trough-shaped installation recessed into the vehicle doors will. With these designs, which are round, oval or right or can be polygonal, the multi-color LEDs are behind a light-transparent cover arranged.
