GR1009989B - Wirelless electric security latch for doors - Google Patents

Abstract

The invented latch is mounted on the inside of the door and secured with screws or rivets as an additional inviolable security means. It works with 12V current; in case of power failure it is able to work, with the energy of one of the two sets of batteries (26) (30), for about 6 x 24 hours. To open the door, in the event of a component’s failure (failure of the terminal switch (16), the receiver (25), the electric motor (9) and the power supply (24)), we release the pins (2) from the striking plate (39) of the door by using the remote control (38). The batteries (26), (30) are automatically charged. The lamps 28 control the batteries charging state. Operation is achieved using a three-strand cable. The receivers are of rolling code.

Description

DESCRIPTION

WIRELESS ELECTRIC DOOR SECURITY ROLLER

This invention refers to a wireless device, which is placed and fixed on the inside of the security door, aluminum and others (with 5 mm screws or rivets) and through the remote control, being inside or outside our house, we can secure and to unlock the door, making it tamper-proof.

There are other such devices, but compared to the mentioned one, they are lacking in several points, such as:

- While they fulfill their purpose as devices, in the event of a power outage, they provide us with minimal operating time through their batteries.

- If they suffer any damage, they create a big problem.

- They do not use rechargeable batteries and change them at regular intervals.

- They do not use rolling code receivers, with the risk of interception.

- They do not provide a battery status monitoring system.

As shown in drawing 2, the second part of the device consists of the following:

23. Plastic box with dimensions 150 X 200 X 70

24. A 12V, 10 A, 120W power supply.

25. A 12V, four channel rolling code receiver for motor operation, but also for coil operation.

26. A set of 12V 18650, 3.7V 3,120mA 3-piece batteries.

27. Two connectors.

28. Two LED indicators which turn off when the batteries are discharged.

29. A 12V two-channel rolling code receiver (magnet only), non-duplicating.

30. A set of rechargeable batteries 12V 3.7V 3.120mA (3 pieces).

31. Two OTO KAPLER 4N 37 to hold the command.

32. A dipole diode for reversing current.

33. A N5822 for alternating operation of the two sets of batteries (in case of failure of one of the two).

34. A ZENER 8.2 to check the condition of the batteries.

35. A 1.2 KΩ resistor to check the condition of the batteries.

36. A battery status control button.

37. One LED indicating good operation of the power supply.

Figure 3 shows:

38. A four command remote control.

39. The opposite

40. A two command remote control.

41. Device cover.

The main operation of the mentioned device is done with 12V electricity from 230V. By using the remote control of the four commands (38), Fig. 3, the receiver (25) is activated and provides us with current to the motor (9), which gives rotational movement to the integrated screw (10), which screws and unscrews ( depending on the command we give it) and this is how the forward movement of the bar (3) is achieved together with the pins (2), Fig. 1, which are locked in the antichrist (39). The same remote control (38) is used to retract the pins (2) and, consequently, release them from the counter (39).

The operation stop of the motor (9) at a specific point is achieved by the two limit switches (16), both for the forward path of the bar (3) of the pins (2), as well as for the rear path.

If over time the device shows any damage, such as damage to a limit switch (16), the receiver (25), the motor (9), the power supply (24) or another component, Fig. 2, then to unlock the pins (2) from the counter (39), we activate the coil (5).

Through the remote control of the two commands (40) and the receiver (29), we supply current to the coil (5) and this in turn the magnet (11) hits the spring blade (17) and the motor (9) is released from the sliding base of (8). Then, by coiling the two return springs (6), the safety pins (2) are released from the anti-cryst (39).

To unclamp the pins (2) from the counter-crystal (39) (in case of failure of the above-mentioned components), we take power from both sets of batteries 18650 12V 3.7V 3.120mA (26), (30), alternately, so that if one of the two sets does not work, let the other work. As long as the LEDs (28) light up, the two sets of batteries (26), (30) are full and in good condition. By pressing a button (36) located in the plastic box (23) of the device, we can periodically check the condition of the two sets of batteries.

- When the two LED lights (28) are on and the two sets of batteries (26), (30) are in perfect condition.

- If one of the two lights (28) goes out, it warns us that one set of batteries (26), (30) has fallen or has a problem. At the same time, the operation of the device continues with the energy of the second set of batteries to unlock the pins (2).

By using the two AUTO COUPLER 4 N 37 (31), it is possible to hold the command we give to the receiver (25), so that the path of the safety pins (2) is completed with only a momentary press of the remote control (38).

In the event of a power cut, by using one diode (32), the return of current from the batteries (26), (30) to the power supply (24) is prevented, thus achieving the operation of the device for approximately six twenty-four hours.

The device has a manual lever (7), so that when there is a fault and we are inside the home, we pull the lever (7) back and the pins (2) are released from the door jamb (39).
