Abstract: An emergency entry and exit apparatus for evacuating people from a building, includes a set of four gears, mounting assemblies, a first chain and a second chain, multiple cabins, a shaft member. The cabins are positioned in series along the length of the first chain and the second chain, and a roof section of each cabin is attached to upper surfaces of the first chain and the second chain via a shaft member, where the first chain and the second chain are driven based on the difference in loading due to the weight of the people entering the cabins on opposing sides of the building which causes the cabins to be displaced along the outer contour of the building during the evacuation process, therefore allowing people to be transferred from one of the floors to another floor via the cabins moving in downward direction.

Abstract: The present invention discloses an apparatus for emergency landing comprising: an extraction vehicle (10), a first adjustable tower and a second adjustable tower (11), a first gearbox (4) wherein said gearbox is mounted on top of said first adjustable tower, a second gearbox wherein said second gearbox is mounted on the top of said second adjustable tower, a third gearbox wherein said third gearbox is mounted on lower right side of said chassis, a fourth gearbox unit wherein said unit is mounted on the lower left side of chassis, a first rubber restrainer (8) wrapped around said first gearbox unit and extended to said third gearbox unit wherein said rubber restrainer is wrapped around said third gearbox unit, a second rubber restrainer wrapped around said second gearbox unit and extended to said fourth gearbox unit, wherein said rubber restrainer is wrapped around said fourth gearbox unit, wherein said first and said second rubber restrainer stabilize said aircraft and reduce initial impact by said aircraft.
