MECHANICAL EMERGENCY ENTRANCE AND EXIT APPARATUS

摘要

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.

主权项

1. An emergency entry and exit apparatus for evacuating people from a building, comprising:
a set of four gears fixedly attached at an upper section, and another set of four gears fixedly attached at a lower section of the building via mounting assemblies, wherein the gears positioned relative to each other in a single plain along the upper section and lower section of the building are interlocked in a loop via a first chain and a second chain in a substantially parallel orientation to each other; and a plurality of cabins positioned in series along the length of the first chain and the second chain, and a roof section of each cabin attached to upper surfaces of the first chain and the second chain via a shaft member, wherein 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 causing the cabins to be displaced along the outer contour of the building during the evacuation process, therefore allowing people to be safely transferred from one floor to another floor via the cabins moving in downward direction, and to allow rescue officials to enter the building through the other cabins which are moving in the upward direction.
