Abstract
Evacuation systems including slide readiness indicators are detailed. The indicators may include lights colored, preferably, red and green and powered using either pre-existing or dedicated electricity sources. Associated switching equipment defaults to illumination of a red light until a slide is satisfactorily inflated and deployed, at which time the red light is extinguished and a green light is illuminated to provide affirmative indication that evacuation via the slide may commence.
Claims11
An inflatable assembly associated with an object containing at least one human, the inflatable assembly comprising:
- a) an evacuation slide assembly configured to be inflated for deployment;
- b) a readiness indicator comprising (i) first and second components, activation of the first component indicating the evacuation slide assembly is not deployed in a manner suitable for a human to evacuate the object and activation of the second component indicating the evacuation slide assembly is deployed in a manner suitable for a human to evacuate the object, and (ii) a separable restraint link;
- and
- c) a switching module directly or indirectly electrically communicating with the first and second components and directly or indirectly mechanically connected to the restraint link so that separation of the restraint link effects a state change of the switching module so as to supply power to one or the other of the first and second components.
An inflatable assembly associated with an object containing at least one human, the inflatable assembly comprising:
- a) an evacuation slide assembly configured to be inflated for deployment;
- b) a readiness indicator comprising first and second components, activation of the first component indicating the evacuation slide assembly is not deployed in a manner suitable for a human to evacuate the object and activation of the second component indicating the evacuation slide assembly is deployed in a manner suitable for a human to evacuate the object;
- and
- c) a switching module (i) directly or indirectly electrically communicating with the first and second components, (ii) configured so as to supply power to no more than one of the first and second components at any given time, (iii) normally supplying power to the first component, and (iv) including a pin, removal of which causes cessation of power supply to the first component and commencement of power supply to the second component.
An inflatable assembly associated with an object containing at least one human, the inflatable assembly comprising:
- a) an evacuation slide assembly configured to be inflated for deployment;
- b) a readiness indicator comprising first and second components, activation of [he first component indicating the evacuation slide assembly is not deployed in a manner suitable for a human to evacuate the object and activation of the second component indicating the evacuation slide assembly is deployed in a manner suitable for a human to evacuate the object;
- and
- c) an outboard rail tube;
- and in which the readiness indicator provides a traffic signal, with activation of the first component signifying evacuation should not occur and activation of the second component signifying evacuation should occur.
A passenger aircraft comprising:
- a) a wing;
- b) an evacuation slide assembly positioned at or adjacent the wing and configured to be inflated for deployment;
- c) a readiness indicator comprising red and green lights and a separable restraint link, activation of the red light indicating the evacuation slide assembly is not deployed in a manner suitable for a passenger to evacuate the aircraft and activation of the green light indicating the evacuation slide assembly is deployed in a manner suitable for a passenger to evacuate the aircraft;
- and
- d) a switching module directly or indirectly electrically communicating with the red and green lights and directly or indirectly mechanically connected to the restraint link so that separation of the restraint link effects a state change of the switching module so as to supply power to one or the other of the red and green lights.
