Tall building escape apparatus

Abstract

A tall building escape apparatus includes two upright sliding rails on one side of a building where two escape exits are located. The sliding rails are cylindrical rods extended from the ground floor to the top floor of the building corresponding to hanging racks located on the top floor. The hanging racks have pulleys mounted thereon to wind a rope between the two hanging racks. The rope has two ends fastened respectively to an escape case. The escape case has retaining rollers with curved periphery to clamp the sliding rails, buffer members on the bottom side, and an entrance/exit opening on one side directing to the escape exit. When a user escapes by descending through one escape case, another escape case is pulled by the rope upwards to enable another user to escape. Thus escape speed is faster, and safety is enhanced and there is no limitation of the applicable height.

1 . A tall building escape apparatus, comprising: 
 two hanging racks located on a top floor of a building fastening respectively to pulleys, the pulleys of the two hanging racks being wound by a rope, the rope having two ends each fastening to an escape case; and    two sliding rails located on one side of the building corresponding to the hanging racks and extended from the ground floor to a front side of the hanging racks;    wherein the escape case has retaining rollers to clamp the sliding rails, buffer members on the bottom side thereof, an entrance/exit opening on one side, and brake devices; the brake devices having clamp members pivotally located on one side of the sliding rail that have outer sides attached to braking pads to clamp the sliding rails and inner sides bridged by elastic members.    
   
   
       2 . The tall building escape apparatus of  claim 1 , wherein the clamp member has a brake line located on an inner side to connect to a pedal.  
   
   
       3 . The tall building escape apparatus of  claim 1 , wherein the sliding rails are cylindrical rods, and the retaining rollers have a curved periphery corresponding to the sliding rails.  
   
   
       4 . The tall building escape apparatus of  claim 1 , wherein the entrance/exit opening has a bottom edge extending to form an extension board directing to an escape exit of the building.
