Abstract
Description
Claims (28)
- Apparatus for escaping from a personnel containment structure such as a building or a vehicle which has a frangible panel mounted within a wall space of the containment structure and wherein there is provided trigger means and at least one protractive device (2) for breaking the frangible panel (10), the protractive device (2) being located proximate to the at least one frangible panel (10), the protractive device comprising means (12) for coupling the trigger to the protractive device (2), propulsion means (40) connected to the coupling means (12) and a solid member (32), the trigger means providing actuation of the propulsion means (40) via the coupling means (12) to propel the solid member (32) from the protractive device (2) into the frangible panel (10) to break the frangible panel (10), characterised in that the frangible panel (10) is coated with a flexible film (7) bonded to one or each of the surfaces of the frangible panel (10) to prevent contact with and spread of shards from the frangible panel (10) on breakage by the solid member (32).
- Apparatus as claimed in Claim 1, wherein the trigger means is activated in response to a sensor activated alarm.
- Apparatus as claimed in Claim 2, wherein the sensor activated alarm is connected to a heat detector and/or a smoke detector.
- Apparatus as claimed in any one of the preceding Claims, wherein the control system includes a programmed delay in initiation of the protractive device (2) to allow manual cancellation of its operation.
- Apparatus as claimed in Claim 2, wherein, the sensor activated alarm is connected to a deceleration detector and/or an orientation detector.
- Apparatus as claimed in any one of the preceding Claims, wherein the trigger means is located in a remote location to the apparatus.
- Apparatus as claimed in any one of the preceding Claims, having a plurality of trigger means.
- Apparatus as claimed in any one of the preceding Claims, having at least one additional protractive device (2a) which acts as a back up.
- Apparatus as claimed in Claim 1, wherein, the coupling means (12) comprises an electrical input connected from the trigger means to the protractive device (2).
- Apparatus as claimed in any one of the preceding Claims, wherein, the propulsion means (40) is provided by a pyrotechnic charge within a space envelope ignited by a thermally sensitive explosive connected to the electrical input, such that ignition of the pyrotechnic charge propels the solid member (32) towards the frangible panel (10).
- Apparatus as claimed in any one of the preceding Claims, wherein the propulsion means (40)is provided by a spring (50) held under tension by the force generated by an electromagnet (52), such that, the spring (50) is released and the solid member (32) propelled towards the frangible panel (10) when the electromagnet (52) is switched off by actuation by the trigger.
- Apparatus as claimed in any one of the preceding Claims, wherein the propulsion means (40) is provided by the force of magnetic repulsion between an electromagnet (58) and a magnetised solid member (32) such that the solid member (32) is propelled towards the frangible panel (10) when the electromagnet (58) is switched on by actuation by the trigger.
- Apparatus as claimed in any one of the preceding Claims, wherein the propulsion means (40) will provide sufficient kinetic energy to the solid member (32) to cause one or more frangible panel (10) to shatter.
- Apparatus as claimed in any one of the preceding Claims, wherein the solid member (32) consists of a piston.
- Apparatus as claimed in Claim 14, wherein the piston is mounted in a chamber (34).
- Apparatus as claimed in Claim 14 or Claim 15, wherein the end of the piston that hits the frangible panel is flat.
- Apparatus as claimed in Claim 14 or Claim 15, wherein the end of the piston that hits the frangible panel is pointed or rounded.
- Apparatus as claimed in any one of the preceding Claims wherein one protractive device (2) is used to break one frangible panel (10).
- Apparatus as claimed in any one of Claims 1 to 17, wherein, one protractive device (2) is used to break a plurality of frangible panels (10,11).
- Apparatus as claimed in any one of the preceding claims, wherein the protractive device (2) is located at the periphery of the frangible panel (10) such that the solid member (32) impacts one of the two surfaces of the frangible panel (10).
- Apparatus as claimed in any one of Claims 1 to 19, wherein, the protractive device (2) is located at the periphery of the frangible panel (10) such that the solid member (32) impacts an edge of the frangible panel (10).
- Apparatus as claimed in any one of the preceding Claims wherein the frangible panel (10) is made from glass.
- Apparatus as claimed in any one of the preceding Claims wherein the frangible panel (10) is made from toughened safety glass.
- Apparatus as claimed in any one of the preceding Claims, wherein an electronic control and diagnostic system (90), checks electrical continuity of the system and determines that sufficient power is available to operate the protractive device (2).
- Apparatus as claimed in any one of the preceding Claims, wherein the electronic control and diagnostic system (90), is connected to an alarm which provides a visible and/or audible warning signal that indicates that the system has a fault.
- Apparatus as claimed in any one of the preceding Claims, wherein the apparatus contains an independent power supply which remains operable even when external power supplies have been severed.
- Apparatus as claimed in any one of the preceding Claims, wherein the trigger signal is activated manually by depressing a button, switch or lever.
- Apparatus as claimed in Claim 27, wherein the button, switch or lever is situated beside the frangible panel (10).
