Abrégé

An aspirator assembly for inflating an emergency slide. The aspirator assembly includes a bell housing, a mixing chamber, and a nozzle assembly. The bell housing includes a ring defining an inlet port at which a check valve is located and into which ambient air can flow. The mixing chamber has an outlet port, The nozzle assembly is located in the mixing chamber and includes plural passageway sections defining concentric rings and cross bars. The passageway sections include internal passageways in communication with plural nozzle jets through which a compressed air is introduced into the mixing chamber to mix with the ambient air. The passageway sections are of an airfoil shape cross-section having a rounded leading end directed towards the inlet port and a trailing end is directed toward the outlet port to reduce air turbulence within the mixing chamber.

Classes IPC  ?

• F04F 5/46 - Aménagements des tuyères
• B64D 25/14 - Toboggans d'évacuation gonflables
• F04F 5/18 - Pompes à jet, p. ex. dispositifs dans lesquels le flux est produit par la chute de pression causée par la vitesse d'un autre fluide le fluide inducteur étant un fluide compressible déplaçant des fluides compressibles pour les comprimer

An emergency escape mechanism is disclosed. A deployable and inflatable slide is located proximate the exit door of a building. When the alarm switch on the alarm box next to the door is set to unlock the door may be opened and a chute or slide falls out to the exterior of the building. A mercury switch or the like is activated as the uninflated slide tilts out which activates an inflation means, preferably a compressed gas cylinder or the like. The slide or chute is anchored to the building by a girt bar anchored in the floor and a plurality of chute support straps. This allows for rapid evacuation of the building. Additionally, the alarm box switch may operate a silent alarm to alert the police of a potentially hazardous situation.

Classes IPC  ?

• A62B 1/20 - Dispositifs pour faire descendre des personnes hors des bâtiments ou dans des situations analogues faisant usage de câbles lisses, perches lisses ou glissières, p. ex. manches, tubes rigides, gouttières, plaques glissantes
• G08B 25/12 - Dispositions pour transmettre une alarme par commande manuelle en cas de sinistre
