RU182731U1 - SIGNAL DEVICE FOR LOCK OPENING CONTROL - Google Patents

Abstract

The claimed technical solution relates to security alarm devices and can be used for audible alarm about unauthorized opening of locks of entrance doors of apartments, garages, warehouses, etc.

The task to which the utility model is directed is to reduce the complexity of the manufacture and installation of the signal device, increase the reliability and efficiency of its work.

The signaling device for controlling the opening of locks contains an audible siren with an integrated unit controlled by a remote control, an autonomous power source and a normally open circuit breaker. For electrical safety purposes, the signal device is powered from a DC source with a voltage of not more than 9 V. One contact of the switch is a metal plate insulated from the lock and door or a similarly insulated armored cup of the lock. The second contact of the switch is the lock itself.

In case of unauthorized opening of the castle, an audible siren instantly turns on, signaling an attempt to enter a secure room, which can scare away an attacker. 1 ill.

Description

The claimed technical solution relates to security alarm devices and can be used for audible alarm about unauthorized opening of locks of entrance doors of apartments, garages, warehouses, etc.

From the prior art, alarm systems are known comprising various non-contact devices for detecting intrusions into secure premises.

Their disadvantages are the complexity and high cost of manufacture, as well as low reliability due to the presence of false positives.

Security devices are also known, when using which, mechanical devices are installed on the doors, including an audible alarm.

Their disadvantage is the use of rather complex mechanical components, which reduces the reliability of the alarm. In addition, a significant drawback of the above security devices can be attributed to the fact that they respond to the opening of the door, and not to the opening of the locks.

A known signal device containing a sound generator, its power source and a sound generator power button located in the zone of movement of the deadbolt (RU patent for utility model No. 128891, G08B 13, publ. 06/10/2013).

The disadvantage of this device is the operation of the sound siren only after turning the key or master key in the lock, as a result of which it may be damaged.

The task the utility model aims to provide is to instantly activate the sound siren when trying to insert a key or master key into the lock, which will scare off intruders and avoid breaking the lock. In addition, the signaling device is designed to inform the owner and other persons (for example, the security service) about an attempt of unauthorized entry into the protected premises.

This problem is solved due to the fact that the signaling device for controlling the opening of locks contains a sound siren with an integrated unit controlled by a remote control, an autonomous power source, a normally open circuit breaker, which is closed when the lock is opened with a key or other metal object (for example, a master key) ensures the sound siren is triggered, one contact of the switch can be a metal plate isolated from the lock and door or isolated the same, similarly, the armored cap of the lock, and the second contact of the switch may be the lock itself. The signal device for electrical safety purposes can be powered by a DC source with a voltage of no higher than 9 volts.

The technical result provided by the given set of features is the preventive operation of the sound siren when trying to insert a key or master key into the lock, which will prevent unauthorized exposure to the lock, thereby eliminating its damage.

In FIG. The functional diagram of a utility model mounted on the inner side of door 1 and containing a sound siren with an integrated integrated unit 2 controlled by a remote control 3, an autonomous power supply 4, an electric circuit switch 5, consisting of two contacts: an insulated metal plate 6 and a lock 7 with key 8.

The device operates as follows. When leaving the premises, the owner closes door 1 to lock 7 and sets the alarm to the remote control status 3. When an unauthorized attempt is made to open the lock, contacts 6 and 7 of the normally open circuit breaker 5 are closed with a key or master key. As a result, voltage is supplied from autonomous power supply 4 to the sound siren 2 and it works. Upon entering the owner’s room, he turns off the alarm with the remote control 3 and freely opens the lock 7 with the key 8.

The use of this signaling device will ensure reliable protection of the premises at minimal cost.

Claims (2)

1. A signaling device for controlling the opening of locks, characterized in that it contains an audible siren with an integrated unit controlled by a remote control, an autonomous power source, a normally open circuit breaker, the circuit of which, when the lock is opened with a key or other metal object, triggers an audible siren , one contact of the switch is a metal plate isolated from the lock and door or an armored pole similarly insulated to the lock, and the second contact of the switch is the lock itself. 2. The signal device according to claim 1, characterized in that it is powered by a DC source with a voltage of not more than 9 V.
