Abstract

Disclosed is a portable alarm apparatus (10) comprising an adhesive suction mechanism (12), a device (3) for monitoring the suction pressure, a device for generating a negative pressure (2), which is connected to the adhesive suction mechanism (12) and maintains the negative pressure in the adhesive suction mechanism (12) substantially constant at a preset value, and an alarm control device (21) that generates an alarm signal when the suction pressure falls below a predetermined threshold value when the preset negative pressure can no longer be maintained.

Claims

1. Transportable alarm device (10, 10′

), comprising the following;

an adhesive suction device (12), by means of which the transportable alarm device (10, 10′

) is attachable to a surface (15, 19, 60, 61) of an area to be surveyed,

a device (3) for monitoring the suction negative pressure, which is connected to the adhesive suction device,

a device for generating a negative pressure (2), which is connected to the adhesive suction device (12) and which maintains the negative pressure in the adhesive suction device (12), when in an attached state, essentially constant at a preset value,

an alarm control device (21), which is connected to a signal output (30) of the device (3) for monitoring the suction negative pressure, wherein the alarm control device (21) generates an alarm signal in case the suction negative pressure decreases below a predeterminable threshold value, when the preset negative pressure cannot be maintained anymore.

2. Transportable alarm device of claim 1, characterized in that the device (3) for monitoring the suction negative pressure and the device for generating a negative pressure (2) are accommodated within the interior of a housing (1, 1′

) and that the adhesive suction device (12) is attached to the exterior of the housing (1, 1′

).

3. Transportable alarm device of claim 2, characterized in that an energy-supply unit is provided in the interior of the housing (1, 1′

).

4. Transportable alarm device of claim 3, characterized in that the energy-supply unit is a rechargeable battery (41).

5. Transportable alarm device of one of the claims 1 to 4, characterized in that the adhesive suction device (12) is formed of one or more adhesive suction means (6, 7, 17) with adhesive suction faces for adhering to the surface (15, 19, 60, 61) of the area to be surveyed.

6. Transportable alarm device of claim 5, characterized in that the adhesive suction device (12) is formed of two or more adhesive suction means (6, 7) that are arranged spaced from each other on an external surface of the housing (1), their adhesion faces being flush with a plane parallel to the external surface.

7. Transportable alarm device of claim 5, characterized in that the adhesive suction device (12) is formed of two or more adhesive suction means (6, 17) that are arranged on two exterior surfaces of the housing (1) perpendicular to each other.

8. Transportable alarm device of claim 5, 6 or 7, characterized in that the adhesive suction means (6, 7, 17) is/are formed of rubber.

9. Transportable alarm device of one of the claims 5 to 8, characterized in that the adhesive suction means (6, 7, 17) has/have a through channel (4, 5), one end of which terminates in the adhesive suction face and the other end of which is connected to the device for generating a negative pressure (2).

10. Transportable alarm device of one of the preceding claims, characterized in that the device for generating a negative pressure (2) is a vacuum pump.

11. Transportable alarm device of one of the preceding claims, characterized in that the device (3) for monitoring the suction negative pressure in the adhesive suction device is connected to the adhesive suction device (12) via pressure lines (8, 9).

12. Transportable alarm device of one of the preceding claims, characterized in that the alarm control device (21) is connected to at least one alarm device, e.g. a GSM unit, a video camera, a sound generation unit, a storage unit and the like.

13. Transportable alarm device of one of the preceding claims, characterized in that the device for generating a negative pressure (2) is, via a pressure line (20), connected to the device (3) for monitoring the negative pressure and, via that, to the adhesive suction device (12).

14. Transportable alarm device of one of the preceding claims, characterized in that the housing (1′

) has a container (90) for safekeeping objects to be protected.

15. Transportable alarm device of claim 14, characterized in that the container (90) accommodated within the housing (1′

) is lockable, and that a negative pressure may be maintained therein, which negative pressure may be monitored by means of a negative pressure monitoring unit, so that an alarm signal is generated when the container (90) is opened without authorization and consequently ambient pressure is reached in the container (90).

16. Use of a transportable alarm device (10) of one of the preceding claims 1 to 13 for attachment to a door area to be surveyed.

17. Use of a transportable alarm device (10′

) of one of the preceding claims 1 to 15 for attachment to a transport container to be surveyed, e.g. a cargo container or a transport vehicle, e.g. a money transporter.
