Building Emergency Exit Means

The present application is an improvement in building emergency exit development particularly as a complete enclosure containing all of the utilities necessary for a one story emergency exit, stackable to any desired height, on the wall of a building.

Modern hi-risers in the form of office buildings and tenements are presently built to accommodate air-conditioned temperature controlled offices and rooms that have non-opening type windows. The threat of smoke or fire is something everyone is concerned about, the air-conditioning ducts would circulate gasses and fumes in moments throughout an entire building, trapping all its occupants, having no means of escape. Toxic fumes from insulation on wiring, smoke from any rubbish or materials in a building each present the problem that requires some thought as to how people can escape from any floor in a building and ascend or descend to a safe area. The classic example occurred at the Patent Office in Arlington where while discussing my prior patent on a emergency fire escape device the examiners asked how anyone could get out of these building that have tempered glass windows and so few exits, and how to escape a smoke condition, it presents a problem in building design. Very often, smoke conditions can be much more dangerous than having an actual fire, the matter of safety is involved that this patent application, is concerned with.

The present application involves one story modular fire-proof units, made of fire-resistant materials and weatherproofed to resist enironmental hazards having permanent or flexible fire escapes, attached therein to the unit, which is actually an enclosure attached to a building. While the illustrated drawings show a four sided enclosure it does not preclude the use of a three sided enclosure to facilitate the desired safety. A four sided enclosure would include having an emergency door in the enclosure and the three sided enclosure would use a emergency door and opening in the building. In new buildings, the cutouts would be made to receive units with or without the doors, that have locking means for entry or exit, in an emergency situation. This would permit occupants to leave the area and descend to safety while it provides an absolutely safe entry for fire-fighters to have access to any floor of a building. Although not shown in the drawings, it would be desirable in some instances to develop these modular units with interlocking pipes that would supply extinguishing fluids for fire-fighting use, and the supply could be attachable from the lowest modular unit on the ground. The units illutrated do not show an exit door placed in the front or sides as may be desired for entry or exit on the lowest unit. However, should other units require doors for exit above the ground level such would easily be available, that in addition would provide the use of my fire escapes shown in U.S. Pat. No. 3,692,145 or the The Emergency Fire Exit Means shown in application Ser. No. 284,630, each providing a safe external means of exit. The present application illustrates a fixed position ladder having safety grip handles placed where needed and the design of the platform affords safety loads plus maneuverability space where people coming through the exit door or windows will not interfere with the people climbing down. It provides potential resting areas in cases of long descent and the symmetrical placement of the opening will afford efficient lowering of victims from any height to the ground floor. The design of these enclosures could be made to accommodate a second opening and additional openings with additional ladders to allow any number of people to use the device and escape to safety at one time. The width of the enclosure would vary in accordance with the requirement, the preferred use of a rectangular design would most likely protrude the least, a matter of choice. The platform would be designed for non-skid safety and the door would conform to fire door standards. The doors can be made to open only from the inside manually and by those with a key from the outside. However, an automatic locking means could work together with an existing alarm system wherein the setting off of an alarm would automatically open all doors, each provided with electrical locks to accomplish this. Another means of exit could include a pull ring such as used on present airplanes, that when pulled would set off the emergency alarm system which would also designate the area of trouble. The use of the present methods employing the necessity of breaking a transparent enclosure to get at the release handle would also do the job. After the occupants have opened the emergency exit door into the building emergency exit means they would use the provided communication phone to describe the problem of fire, smoke or victims that require emergency aid. Each of the enclosure modular units are provided with a ventilation system where required, the drawings show electrical and ordinary ventilation means. Being on the outside of a building it would limit the smoke automatically provided that that each exit door had automatic means of closing with an ordinary door check, returning to a closed not a locked position. If the smoke was coming into the enclosure from the outside, the vent could be closed from the inside on one side of the enclosure and opened manually on the other side permitting fumes and smoke to leave. The top modular unit placed on the highest story would have a ventilated cover allowing the rising heat and smoke to escape and furthermore can be provided with a large top ventilating fan having its own power source in case of failure and means at the bottom for adaptation of a secondary power source in case of failure. If a 12 Volt system were used it could then be operated by the alternator of a fire truck or car or separate generator if desired, having battery or AC supplied current. The ladders lock into the modules as illustrated on the drawings providing vertical rigidity for handling great loads. The communication system phone would also have a connection jack so that when the modules are placed together the proper connections have been made. This phone would have a station number on it and could be connected to the fire department or to any desired source. Means is shown in the modular wherein when the exit door or window is opened it will set-off an alarm that is battery operated as shown or can be connected to any source of power. The enclosure unit is shown having an emergency exit light and could have other lights as also shown. Several methods of attaching each module is shown in the accompanied drawings and it would be practical on big buildings to place these units side by side, locking them together and to the building into one integral unit. One of the plaforms is shown having the cutout placed under the exit which would change the order of descent for those who fear height, so that when they look down they will only see the floor below, it will have psychological effects. Also the placement of the cutout can be made so that it is neither under the exit or the ladder and placed inbetween. In providing the modular emergency exit means without a exit door, it would be locked on the building and the proper size cutout made into the building, having its own door and frame to meet fire-requirements, where available. The enclosure module can be raised into place by ordinary rigging methods using block and tackle or by a crane, when placed upon a building already built, locking each unit into each other and to the building. The units show lifting rings on top that can also be placed upon the sides if necessary, the points of lifting would be reinforced to carry the weight. The anchoring base can be made adjustable to set the proper height of the bottom unit which after being set would be reinforced permanently in that position. Units would be made from standard and special heights of buildings or provided with adapters, not shown in the drawings, for adaptation so that the modules will fit any building floor height required. Bolting the emergency exit enclosures on to buildings by bolts inside the enclosure or by bolting the exterior flange is a matter of choice and decor. These units can be made having air ducts to each floor separately or in any combination of floors and therefore keep the enclosure entirely free from fumes and smoke, powered by emergency supply means internally or externally. The bolted areas of the exterior would be covered by facia covers so that the modular exit enclosure would become a functional and good looking addition to modern buildings and further, can be provided of aluminum, stainless steel or fibreglass in any colors, or other materials as may be required for specific use as an emergency exit means. Such as in the case of emergency fire escape devices where there are no codes todate, it is anticipated that the presentation of these new modular exit units will also require new building and fire codes. The modular units can be made in more than one story as units.
