(54) | Elevator as an escape from fire |
(57) This invention is relative to an Elevator as an escape from fire. It means a floor
of the building initially set on fire, the signal of fire will be directly transmitted
into a computerized operating-system of computer set up on the elevator via a series
of security equipments which makes the Elevator as a safe escape to bring function
into full play. The main facilities contains: an auto-selected system to select stop
on the floor which is on fire (or stop upper floors and to stop next one or 2-floor
so that the people on upper floors can escape from fire quickly )and non-stop the
lower floors (or to auto-select stop on the floor ); an electro-generator with a controllor-computered
to provide power by itself instead of public-power; an air-purifier built up at the
side of the elevator; a steel cab with materials of fire-proof and heat-resistance
in the wall as well as a steel door of the inlet in every floor with same materials
for fire-proof, all these facilities make a security guide system. |
1. Facilities occupied a great number of area and cost too much for them.
2. Usages to be well trained, and otherwise, an anticipative effects can not be obtained at a pressing need, or with difficult and complex operation it would be easily make an error while an emergency happened.
3. Less efficiency, it could not rescure many persons at one time or rather difficult to maintain it at other times that makes no effect when emergency.
a). At any time it is possible to switch off power when building is on fire and probably keep people waiting on spot.
b). People at lower floor (or next floor under the floor on fire ) would squeeze into the cab so that overload could occur and waste time.
c). Common elevators are unable to provide for fire-proof or insulation from heat for cab, an unexpected demage or hurt might be happened.
d). The door of the cab is not close or tight enough so as to suffocate people in the cab by heavy smoke.
e). No equipment of air purifier to fill fresh air for people in cab.
A). To receive a signal by receiver from which the floor is on fire and to cut off power from lower floors (from the next floor of firing; people in next floor could run away from safety ladders), the elevator can run from the floor on fire direct down to the ground without stop, ( or to stop next floor or 2 under the floor setting fire ( so as to save time for stops between the firing floor and the ground and to avoid from congestion of people.)
B). A proprietary electro-generator of the elevator set up on top of the building would automatically switch from public electrocity to self-supporting power; and then, immediately starts operating the elevator after recieving signal from fire alrm that the people on the firing flooor can get in the cab to run away safely.
C). The matellic cab constructed with materials of fire-proof or insulation inserting between the wall to avoid high temperature or fire from the cab or shock.
D). The inlet of cab on every floor will be fitted with air-tight and stainless-door so as to avoid from penetration of fire and smoke into the cab.
E). To set up an air-purifier or filter to the side of the cab in order to have fresh air for the persons in cab.
a) Figure 1 shown the locations of apparatuses on the floor.
b) Figure 2 shown the location on each position of apparatuses.
ILLUSTRATION:
(1). Fire alarm system: (11) Fire detector, (12) Fire alarm set box, (13) Fire signal from the floor on fire. (14) indicator--while fire alarm rings and indicate location on fire.
(2). Controller of the elevator: (21) to control the invention of this elevator selected to stop or run.
(3). The proprietary electro-generator: (31) auto-starter for generator. (32) auto-switch for self-supporting power for the elevator.
(4). Cab of the elevator: (41) the heat-proofing materials or insulations between the matellic wall of the cab, (42) doors of the cab, (43) rims of the doors to prevent from penetration of fire and smoke into the cab.
(5). Air-purifier (or filter): (51) Auto-switch of air-purifier (or filter) and a fan.
(6). A inlet of the elevator in every floor with airtight and stainless-steel door: (61) fire-proofing pads around the door.
(7). Cabin for control of the elevator built up on the top of the building.
THE MERITS OF THIS INVENTION.
1. The fire alarm system and the elevator, which were already built up in the building, are conbined with the invention of computerized-controller to command the elevator ,to receive fire signal, and to cut off public electrocity and to provide self-supporting power for the escape equipments that makes people in this building saving much more money.
2. Originally, the elevator is disallowed to use while a fire happened; now, after adoption of this invention changes the conventional elevator as a useful escape equipment. It is fitted for customary use of elevator.
3. The cab of the elevator can be contained at least half dozens of people at one time to run quickly away from fire without stopping the lower floors.(or quick stopping on the next one or 2-floor from the floor on fire. It is the best equipments of escape for big building.
4. It is no problem on safetibilty as the new computerized invention is set up.
