Glass Breaking Device

Abstract

A device for breaking glass, arranged to be mounted on a pane of a breakable substrate, and being actuatable to break the pane. In one embodiment, the device comprises a base, a plunger moveable relative the base and a pin extending from and axially moveable relative the plunger, wherein the plunger is moveable relative the base from a retracted to an extended position so when the base is placed against a first pane, a distal end of the pin strikes and breaks the first pane, and the pin is moveable relative the plunger from a retracted position to an extended position, with the plunger in its extended position, such that the distal end of the pin strikes and breaks a second pane parallel to the first pane. Preferably, the plunger and pin are biased to an extended position each by a biasing means.
