A method of enabling people, including the injured, the elderly, or disabled persons to escape entrapment from or to bypass the levels of a high-rise building that is impassable due to flame, smoke or heavy damage, safely with very little effort or assistance, comprising:
- (a) giving evacuees simple, intuitive steps for implementing egress, comprising:
- (1) stepping inside an obliquely angled egress booth,
- (2) closing a cylindrical door of said egress booth, and
- (3) pressing a button to activate a trap door at the bottom of said egress booth,
- (b) pre-qualifying egress safety conditions, before permitting evacuces to exit, comprising:
- (1) providing a complete escape path integrity sensing means which will actively monitor the wholeness of a plurality of generally y-shaped descent tubes and an inflatable slide, including verification that a plurality of support poles are in properly deployed position, for keeping said trap doors closed should damage be detected,
- (2) providing a collision avoidance sensing means which will time the opening of said trap doors at an opportune moment when collision between evacuees in diagonal and vertical descent is estimated to be avoided,
- (3) providing an access regulating means which will prevent said cylindrical doors of said egress booths from being opened while said trap doors have not yet returned to a closed position, immediately after evacuees exit,
- (4) providing an optional initial descent validating means which will verify the arrival of a test dummy onto said unflatable slide, after passing through all vertical sections of said descent tubes, prior to activating said trap doors assigned to said inflatable slide, and
- (5) providing an egress controlling means which will pre-qualify compliance to signals to open said trap doors, by validating if said egress booths are occupied and checking if said cylindrical doors are closed, applied in conjunction with all aforementioned egress safety means,
- (c) transporting evacuees after all previously mentioned egress safety conditions have been met, further employing additional safety features, comprising:
- (1) covering a complete path used for descent with non-stick lining at predetermined locations, so as not to cause harmful abrasion to exposed skin,
- (2) opening said trap doors at a predetermined instance that complies with all previously mentioned egress safety conditions, causing evacuees to slide through passageways beneath said trap doors then through diagonal sections of said descent tubes, wherein said passageways and said diagonal sections approximate the oblique angle of said egress booths to facilitate the sliding motion,
- (3) transitioning evacuees thereafter to vertical sections of said descent tubes, where the rate of descent of the evacuees are slowed down appreciably to less than free-fall speed due to the expansion of the elastic components of said descent tubes,
- (4) protecting evacuees in diagonal and vertical descent against flame by covering said descent tubes with a fire-proof material, generally corrugated so as not to hamper the required elastic properties of said descent tubes,
- (5) distancing evacuees considerably away from fire and smoke by locating the vertical sections of said descent tubes substantially near the extremities of said support poles,
- (6) supporting the weight of multiple evacuees safely, by complementing each said descent tube generally with a single piece cargo netting interlaced with a breathable cladding of elastic material so as not to sacrifice required elastic properties,
- (7) supplying evacuees with sufficient ventilation, by utilizing a breathable elastic lattice that is affixed to predetermined vixceral areas of said cargo netting, and by furnishing said fire-proof material with openings at carefully predetermined locations, and
- (8) providing slide means equipped with self-integrity monitoring, which enables multiple evacuees to either disembark swiftly in an orderly fashion, or be simultaneously fetched and assisted by emergency personnel,
- (d) providing an overall system regulating means which will orchestrate the interaction between all aforementioned means and components used in said method, to establish proper deployment, autonomous operation and orderly shutdown, including overriding predetermined safety features if deemed necessary by authorized personnel,
- whereby said method overcomes the limitations of an elevator system, by safely enabling evacuees to randomly egress from different vertical locations of said high-rise building in a continuously streaming fashion, while requiring a comparatively minimal amount of power for proper deployment and autonomous operation,.
- whereby said method overcomes the inordinate amount of time, excessive physical exertion and prolonged mental concentration demanded from evacuees using an emergency stairwell, by enabling all evacuees, regardless of physique or health condition, to be directly transported to safety with approximately equal speed and efficiency, and
- whereby said method seeks to address the root cause of truly unnecessary and avoidable multiple fatallities that are suffered when people in burning high-rise buildings who are still conscious and mobile have become totally cut-off from rescue, specially above or at the level of the fire, by empowering all evacuees with a save, rapidly available, swift yet coordinated, direct, non-strenuous and verfiably complete escape path, a critical combination of features which are not provided by emergency stairwells or elevators.
