Abstract

A self-contained apparatus for breaking a glass pane, wherein apparatus includes a housing which can be attached to a glass pane, initiating means breaking said glass pane and activation means for encouraging the initiating means to impact the glass with sufficient force to cause the glass pane to break or smash, wherein the apparatus can be retro-fitted to an existing window and is switchable between a sleep mode and active mode. The apparatus is further associated with identification means for aiding in the identification of a user upon activation of the apparatus which acts as an anti-vandalism system to prevent the device from being interfered with.

Claims

1. Self-contained apparatus for breaking a glass pane, said apparatus comprising:

a housing configured to be attached to the glass pane, and comprising a protective panel or barrier;

an initiating means for breaking said glass pane; and

an activation means for encouraging the initiating means to impact the glass pane with sufficient force to cause the glass pane to break or smash, wherein the activation means is located behind the protective panel or barrier, and the protective panel or barrier is configured to be broken or removed to enable access to the activation means.

2. Self-contained apparatus, as claimed in claim 1, wherein the initiating means is configured to break through multi-glass panes, such as double glazing or reinforced glass, simultaneously.

3. Self-contained apparatus, as claimed in claim 1, wherein the protective panel or barrier comprises a material which more easily breaks or shatters than the glass pane sought to be broken by the initiating means, and which offers minimal risk of damaging the skin or tissue of the user or nearby personnel.

4. Self-contained apparatus, as claimed in claim 3, wherein fragments of the broken or shattered material are not capable of damaging human skin tissue.

5. Self-contained apparatus, as claimed in claim 4, wherein the material is SAFEGLASS™
