Rescue sleeve for buildings

Abstract

A rescue system for evacuating individuals through a window frame of a high-rise building. The rescue sleeve ( 18 ) is foldable between a compact, standby position and an extended, sloping down to ground level position. Means ( 92, 94 ) are provided for activating the ejection of the sleeve ( 18 ) from the standby position within a compartment ( 12 ) to the extended position. The system ( 20 ) is operable to anchor the compartment ( 12 ) to the window frame in a self-supporting fashion.

1 . A rescue system for evacuating individuals through a window frame of a high-rise building comprising a rescue sleeve foldable between a compact, standby position and an extended, sloping down to ground level position, means for activating the ejection of the sleeve from the standby position to the emended position, and a compartment for accommodating the sleeve characterized by a system operable to anchor the compartment to the window frame in a self-supporting fashion.  
   
   
       2 . The rescue system as claimed in  claim 1  further characterized in that the system comprises upper and lower jaw members configured to embrace respectively the upper and lower window frame sides from the inside of the outer wall.  
   
   
       3 . The rescue system as claimed in  claim 2  further characterized in that the jaw members are carried each by a pair of rails, means being provided for displacing one pair of rails away from the other pair of rails in parallel to each other.  
   
   
       4 . The rescue system as claimed in  claim 3  further characterized in that the rails are supported by rollers running along rails extending perpendicular to the rails.  
   
   
       5 . The rescue system as claimed in  claim 3  further characterized in that the displacing means comprise a pneumatic cylinder and piston coupled to the rails by pivotal scissors arm assemblies, a compressed air container being provided for selectively driving the piston.  
   
   
       6 . The rescue system as calmed in  claim 1  further characterized in that the sleeve ejecting means are selectively operable by pressurized air charged from the container.  
   
   
       7 . The rescue system as claimed in  claim 6  further characterized by a bellows envelop surrounding the system.  
   
   
       8 . The rescue system as claimed in  claim 1  further characterized in that the compartment is adapted to be carried and lifted by mobilized boom.  
   
   
       9 . The rescue system as claimed in  claim 8  wherein the boom comprises a beam freely insertable into and out of a channel integrally formed with the compartment.  
   
   
       10 . The rescue system as claimed in  claim 1  wherein the sleeve is adapted to slope down in an inclined fashion.  
   
   
       11 . The rescue system as claimed in  claim 1  wherein the sleeve is adapted to slope down in a spiral fashion.
