Description

SAFETY DEVICE

The invention relates to a security device against unwanted intruders for protecting a passage, with one or more vertically and/or horizontally mounted electrical channels, a connection to an electrical power supply and/or a battery, an electronic switch connected to a capacitance measuring device and a remote-controlled light and/or an acoustic signal generator.

An alarm device is known from the numerous types of motion detectors and break and/or vibration switches. In these cases, an intrusion into an area or a vibration triggers the alarm. The credibility of an alarm device is called into question by many false alarms, whether intentional or due to a technical error. As soon as an alarm is activated several times without any apparent reason, it is switched off or no longer acknowledged.
To install the well-known alarm devices and to conceal the necessary electrical connections beneath the wall surface, complex cabling work is often carried out.

It is an object of the invention to avoid the disadvantages described above in such an effective device which prevents unwanted penetration.

* ft

The solution is that the electronic alarm device consists of two net-like hammocks that hang parallel to each other like curtains at a relatively short distance from each other at the place to be protected. The net-like hammocks consist of relatively thin wire channels and are suspended from the top on one or, preferably, two rollers.
In principle, the rollers are spring-supported, like those of the well-known roller blind devices, so that they roll up the mats as soon as they are not needed.
Preferably, the support rollers are housed in a protective housing. The housing is hung in the desired location so that the net-like hammocks can be pulled out of the bottom of the housing and hang freely.
At the lower ends, the net hammocks are connected to a second housing. This housing hangs along the entire length of the lower end of the net hammocks and contains the power supply, electronic switches and a light indicator. The lower housing loads the net hammocks so that they hang smoothly and with a constant spacing.

The safety device is activated by a switch. During operation, a relatively small amount of electrical current is supplied to the net-like hammocks from a battery or a mains connection, so that the net-like hammocks are each connected to different phases.
The net-like hammocks are advantageously arranged in such a way that the square field of the first net-like hammock is broken through by the second net-like hammock. This reduces the opening size of each field by a quarter. In the above-mentioned arrangement, the net-like hammock consists of several square fields in the front view, each of which consists of two net-like hammocks.

When a body part or an object is passed between the fields, this causes an electrical connection between the two net-like hammocks. The net-like hammocks, which are supplied with a small amount of electrical voltage, are connected to an electronic sensor switch.

When an electrical connection is made, including one made by the human body, a relatively high electrical voltage is sent to the net-like hammocks by the electronic sensor switch. The high voltage causes an unpleasant shock caused by the electrical connection.

The current is kept so low that the relatively high voltage cannot cause any health damage to humans or animals.

The power supply is dimensioned in such a way that the device can output a high voltage several times.

The activation of the safety device is indicated by a light indicator.

When the safety device is activated by the penetration of a foreign body, this action is signalled by one or more light and/or sound signalling devices and/or is detected by a separate device at a limited distance by a high-voltage sensitive sensor. This receiving device is advantageously equipped with a light and/or sound signal and an off switch.

The receiving device is a portable device and is powered by a battery and/or electricity. The wearer of the receiving device is alerted to a break-in in the receiving area of the device by a light and/or sound signal.

The receiving device is advantageously equipped with signal inputs and outputs. The outputs allow additional signaling devices to be installed or connected to the receiving device.

The safety device can advantageously also be equipped with a light, sound signal generator and/or several other types of alarm devices.

Fig. 1 shows a front view of a safety device in the rolled-up state. The wire-like electrical ducts (1 or 2), with advantageously horizontally and vertically arranged belts, form a net-like mat which, due to its hanging state, is referred to here as a net-like hammock.

The safety device consists of two net-like hammocks, each made separately from wire-like electrical channels (1 and 2).

The opening fields of the first net-like hammock (1) are arranged offset so that they are optically divided into smaller opening fields from the front view through the second hammock (2).

The vertically arranged wire-like electrical ducts (1) are attached to a roller (31) on the top. The rollers (31 or 32) are basically spring-supported roller blind devices. The rollers (31 and 32) are advantageously mounted rotatably in a housing (3).
A housing (4) is attached to the underside of the vertically arranged wire-like electrical ducts (1). The housing (4) advantageously contains an operating switch (5) and a light display (6) which indicates the operation of the safety device.
The safety device is electrically supplied by a mains connection or, advantageously, a battery. In the housing (4) hanging at the lower end of the vertically arranged wire-like electrical ducts (1 or 2), an opening (7) of a chamber is provided in which the battery or batteries and/or the mains connection socket are accommodated.

Fig. 2 shows a vertical cross-section of the safety device in the unrolled state, and through a window (8 and 9). The lower housing (4) is located immediately below the upper housing (3). In this state, the safety device is inoperative and cannot be switched on. The net-like mats (1 and 2) are advantageously wound around the rollers (31 and 32).

Fig. 3 shows a vertical cross-section of the safety device in the rolled-up state and through a window (8) with a tilted-open window sash (9).

The net-like hammocks (1 and 2) hanging downwards are wound up by the respective rollers (31 and 32) located in the upper housing (3) and advantageously cover the entire surface of the window reveal.

In this state, the safety device is ready for operation and can be activated using the switch (5) located on the lower housing (4).

Fig. 4 shows a perspective vertical cross-section of the safety device in the rolled-up state. The rollers (31 and 32) for winding up net-like hammocks (1 and 2) in the upper housing (3) are shown here. The lower housing (4) is also shown here. The opening (7) of the chamber for the accumulator, or the batteries, and/or the electrical mains connection and the operating switch (5) as well as the operating indicator light (6) are assigned to the lower housing (4).

Fig. 5 shows a perspective view of the receiving device (10). This device (10) is a portable device that receives a high electrical voltage triggered within a radius of advantageously 100 m and triggers a visual and/or audible alarm. The receiving device (10) is equipped with a light signal display (11) and a relatively loud alarm sounder (12). The light signal display (11) and the alarm sounder (12) can be switched off using an off switch (13). The receiving device (10) is equipped with an output socket through which additional alarm signalers can be connected in parallel to the receiving device (10). The receiving device (10) is electrically supplied by an accumulator, or a battery and/or a mains connection.
