Abstract:
An exterior emergency escape system for use on a multi-storied building having an exterior and a roof with a cornice, said system comprising:a) an escape module;b) cables; andc) apparatus for moving said escape module vertically along the exterior of the multi-storied building;wherein said escape module is for holding people escaping from the multi-storied building;wherein said escape module is for moving along the exterior of the multi-storied building;wherein said cables are for suspending said escape module from the cornice of the roof;wherein said escape module is for aligning with an egress through the exterior of the multi-storied building for allowing the people to enter said escape module from the multi-storied building;wherein said escape module comprises a floor;wherein said floor of said escape module is generally rectangular-shaped;wherein said floor of said escape module is for riding smoothly along the exterior of the multi-storied building;wherein said floor of said escape module has four corners;wherein said escape module comprises four corner posts;wherein said four corner posts of said escape module extend vertically upwardly, respectively, from said four corners of said floor of said escape module to terminal ends;wherein said escape module comprises rails;wherein said rails of said escape module are vertically spaced-apart;wherein said rails of said escape module extend horizontally from one rearmost corner post of said escape module forwardly to one aligned forwardmost corner post of said escape module, sidewardly to another forwardmost corner post of said escape module, and rearwardly to another rearmost corner post of said escape module;wherein said escape module comprises intermediate posts;wherein said intermediate posts of said escape module are horizontally spaced-apart;wherein said intermediate posts of said escape module extend vertically across said rails of said escape module, and together therewith, is for preventing the people from falling out of said escape module;wherein said escape module comprises a pair of gable trusses;wherein said pair of gable trusses of said escape module are planar;wherein said pair of gable trusses of said escape module are vertically-oriented;wherein each gable truss of said escape module has a base;wherein said base of each gable truss of said escape module has ends;wherein each gable truss of said escape module has a pair of equal legs;wherein said pair of equal legs of each gable truss of said escape module extend inclinely and upwardly directly from said ends of said base, respectively, to an apex where they meet;wherein said base of one gable truss extends directly from a terminal end of said one rearmost corner post of said escape module forwardly and directly to a terminal end of said one aligned forwardmost corner post of said escape module;wherein said ends of said base of said one gable truss of said escape module are coincident with said terminal ends of said one rearmost corner post of said escape module and said one aligned forwardmost corner post of said escape module;wherein said base of another gable truss extends directly from a terminal end of said another rearmost corner post of said escape module forwardly and directly to a terminal end of said another forwardmost corner post of said escape module;wherein said ends of said base of said another gable truss of said escape module are coincident with said terminal ends of said another rearmost corner post of said escape module and said another aligned forwardmost corner post of said escape module;wherein said apparatus comprises a pair of support brackets;wherein said pair of support brackets of said apparatus are vertically-oriented;wherein said pair of support brackets of said apparatus are parallel to each other;wherein said pair of support brackets of said apparatus are horizontally spaced-apart from each other;wherein said pair of support brackets of said apparatus are for extending outwardly from the exterior of the cornice, above and straddling the egress in the multi-storied building;wherein each support bracket of said apparatus is triangular-shaped;wherein each support bracket of said apparatus has a first leg;wherein said first leg of each support bracket of said apparatus is vertically-oriented;wherein said first leg of each support bracket of said apparatus has a lowermost end;wherein said first leg of each support bracket of said apparatus has an uppermost end;wherein said first leg of each support bracket of said apparatus is for extending vertically along the exterior of the multi-storied building;wherein each support bracket of said apparatus has a second leg;wherein said second leg of each support bracket of said apparatus is horizontally-oriented;wherein said second leg extends horizontally outwardly from said uppermost end of said first leg, to an outermost end;wherein each support bracket of said apparatus has a hypotenuse;wherein said hypotenuse depends skewly from said outermost end of said second leg, to said lowermost end of said first leg;wherein each support bracket of said apparatus has a free outermost corner;wherein said free outermost corner of each support bracket of said apparatus is formed where said second leg meets said hypothenuse;wherein said free outermost corner of each support bracket of said apparatus has a bearing thereon;wherein said bearing is disposed on top of said free outermost corner;wherein said apparatus comprises an axle;wherein said axle of said apparatus is horizontally-oriented;wherein said axle of said apparatus is rotatably supported through said bearing on each support bracket;wherein one end of said axle of said apparatus extends past an associated support bracket of said apparatus;wherein said apparatus comprises a pair of spools;wherein said pair of spools of said apparatus are disposed on said axle for rotation therewith;wherein each spool of said apparatus is positioned adjacent to, and inward of, an associated support bracket of said apparatus;wherein each spool of said apparatus has an associated cable of said apparatus wound therearound;wherein said apparatus comprises a chain and pulley;wherein said chain and pulley of said apparatus comprise a sheave;wherein said sheave of said apparatus is operatively connected to said axle of said apparatus;wherein said chain and pulley of said apparatus comprise a center pin;wherein said center pin of said apparatus extends through said sheave of said apparatus for rotation therewith;wherein said chain and pulley of said apparatus comprise a drive gear;wherein said drive gear of said apparatus is a worm gear;wherein said worm gear of said apparatus is disposed on said center pin of said apparatus for rotation therewith;wherein said chain and pulley of said apparatus comprise a driven gear;wherein said driven gear of said apparatus is positioned on said one end of said axle for rotation therewith; andwherein said driven gear of said apparatus engages with said drive gear of said apparatus.
