Abstract

An alarm device includes a portable alarm emitter, the portable alarm emitter being configured to detect a change in an electrical property of a sensor element which is connected to the portable alarm emitter and to signal an alarm if a change is established. The portable alarm emitter and the sensor element are separate units configured to be interconnected with electrical contact. The portable alarm emitter is a reusable unit. The sensor element is a disposable unit.

First claim

1 : An alarm device, comprising:
a portable alarm emitter, the portable alarm emitter being configured to detect a change in an electrical property of a sensor element which is connected to the portable alarm emitter and to signal an alarm if a change is established; wherein the portable alarm emitter and the sensor element are separate units configured to be interconnected with electrical contact; wherein the portable alarm emitter is a reusable unit; and wherein the sensor element is a disposable unit.

2 : The alarm device according to claim 1 , wherein the sensor element is a single-use unit which is used up by a process of securing and unsecuring an article to be protected.

3 : The alarm device according to claim 1 , further comprising:
at least one reserve of sensor elements from which or of which at least a single sensor element can be taken for connection to the portable alarm emitter.

4 : The alarm device according to claim 3 , the at least one reserve of sensor elements comprises at least one of the following:
a plurality of identical individual sensor elements; or a spool of continuous sensor element material from which a sensor element can be taken by butting to length, the sensor element material being adhesive at least on one side.

5 : The alarm device according to claim 1 , wherein the sensor element is strip-shaped with at least one electrical line configured to be electrically contacted by the portable alarm emitter which extends along the longitudinal extension of the strip-shaped sensor element and which is enclosed by the material of the sensor element and further configured to be electrically contacted by the alarm emitter at at least one end of the sensor element or which extends on at least one surface of the sensor element.

6 : The alarm device according to claim 1 , wherein the portable alarm emitter comprises at least one receiving region in which the sensor element is configured to be connected to the portable alarm emitter with electrical contact.

7 : The alarm device according to claim 6 , wherein the portable alarm emitter comprises at least two receiving regions which are configured to connect different types of sensor elements.

8 : The alarm device according to claim 6 , wherein a receiving region is formed as an opening, into which at least one end of a sensor element is configured to be inserted to produce a connection with electrical contact, or is formed as an insertion region, which is formed between two housing parts of the portable alarm emitter which are pivotable with respect to one another, and into which at least one end of a sensor element is configured to be inserted after pivoting open the housing parts, and which is electrically contactable by pivoting closed.

9 : The alarm device according to claim 1 , wherein the portable alarm emitter comprises a communication module configured to send a message signalling an alarm to a mobile telephone if the alarm is triggered.

10 : The alarm device according to claim 9 , wherein the portable alarm emitter is configured to be deactivated by a message communicated to the portable alarm emitter and received by the communication module.

11 : The alarm device according to claim 9 , wherein the portable alarm emitter is configured to send and/or receive messages via the communication module for a limited time period or a limited number of communications, and to extend the time period or increase the number.

12 : The alarm device according to claim 1 , wherein the portable alarm emitter comprises at least one actuation element configured to activate the portable alarm emitter, wherein the at least one actuation element comprises at least one key.

13 : The alarm device according to claim 1 , wherein the portable alarm emitter comprises at least one illumination device configured to optically signal an alarm, to display an optical confirmation to confirm an activation or deactivation action, and to provide continuous or intermittent illumination.
