## Background
BACKGROUND OF THE INVENTION
The present invention relates to equipment that can be readily used in escaping from a high rise building, i.e. one in excess of twenty stories high, when the usual stairways and elevator systems are not available due to some emergency situation. More specifically, it relates to the equipment utilized and also the method of using the equipment to expeditiously evacuate a building under adverse conditions. There are several situations where a person on the upper floors, for example, 30th floor, could become trapped at that level due to a fire, bomb, explosion or other condition where the elevators and the stairways are not available due to the presence of smoke, fire or possibly hostile persons. In addition, the present invention also relates to the method of using the equipment to allow for successful evacuation of someone trapped at that level under these conditions. The usefulness of this invention has been highlighted by the tragic events of Sep. 11, 2001 when the terrorists took control of a plurality of aircraft and flew them into the Twin Towers of New York City. It can readily be seen that provision of the Twin Towers with equipment such as disclosed herein would have resulted in the saving of many lives.
SUMMARY OF THE INVENTION
The present invention relates to equipment that can be readily moved about from place to place in a convenient carry-on bag with wheels and a pull handle which provides storage for a plurality of ropes lengths, at least one harness, a plurality of anchoring straps, and a descent controller for controlling the rate of descent by the user. Additionally, the carry-on bag would contain a piece of equipment that would be utilized for the controlled breaking of windows in the room, allowing for the escape there through.
Once it is decided that this escape equipment is to be utilized, the carry-on bag is opened, the one or three anchor straps are secured, the harness is donned and the window breaking tool is removed from the carry-on bag and utilized to break the window of the particular room the user is located in. The descent controller is attached to the first length of rope in the carry-on bag and the carry-on bag with the remaining lengths of rope and weights therein thrown from the room through the broken window to the ground in preparation for the user to attach his harness to the rope and proceed to descend through careful use of the controller.
In this example, a single person was lowered through the use of the escape equipment; however, there are situations where a second, inexperienced or otherwise, person could be lowered with the same equipment. In this situation, the second person would be equipped with a harness that is securely attached to the harness of the experienced used and the experienced person would be the person-in-charge, with the second person riding tandem to the first person.

Referring now to FIG. 1, there is shown an elevational view of the portable carry-on bag 50 with its extendable pull-handle 51 extended for easy mobility as one hustles through crowded airport terminals. Portable carry-on bag 50 is an FAA certified bag that has been certified as “carry-on luggage” when boarding U.S. aircraft and certified for stowage either in the overhead storage bin or beneath the seat stowage. As shown, carry-on bag 50 is provided with a pair of ground engaging wheels 52 that allow for smooth rolling contact with the floor 52A. Carry-on bag 50 is also provided with a handle 53 for use when use of the pull-handle 51 would not be convenient, such as when trying to stow the bag in an overhead storage bin. A third handle 53A, located at one end of carry-on bag 50 is also useful in manipulating bag 50 when stowing. As shown, all the necessary equipment necessary for an emergency evacuation is stowed within carry-on bag 50 ready for use in a moments notice.
Turning now to FIG. 2, there is shown the portable carry-on bag 50 positioned on the floor with its lid 54 unzipped and exposing the contents of carry-on bag 50. As shown, all of the contents have been removed from the interior of carry-on bag 50 except some 200 feet of pre-rigged rope into a plurality of bundles that are kept straight by the positioning of rubber bands 55A near opposite ends of the rope 55. The terminal end of rope 55 is securely fastened to the inside of carry-on bag 50 (not shown) and after it is thrown outside the exit portal, it automatically unravels itself during descent, popping the rubber bands 55A, with the carry-on bag 50 acting as a rope stabilizer. As can be seen, rope 55 is rigged into a plurality of continuous bundles and shown with a portion thereof exiting the carry-on bag 50 onto the floor where descent controller 65 is shown attached to rope 55 by the rope 55 passing through descent controller 65. There is also shown a nylon bag 56 which is used to store the harnesses which are not visible since they are inside nylon bag 56. A locking carabiner 57 connects to the rescue harness 60. Rope 55 continues to the point where another carabiner is attached to three more carabiners 56 which are attached to one end of anchor straps 58. Three anchor straps 58 are usually used when there is a dual descent, i.e. two persons descend simultaneously. As shown, there are three such straps 58 with locking carabiners 56 attached to each end thereof, the function of these anchor straps will described in more detail later.
There still remains a couple of pieces of equipment that are contained in the portable carry-on bag 50 that are not illustrated in this figure, namely, the harnesses for both single and dual evacuation and also a window breaking tool utilized for breaking the window in preparation for exit therethrough.
FIG. 3 is an illustration of the anchor clamp 90 that is used for quick attachment of the rope 55 when there is a “one person” evacuation. In the instance of a single evacuation, the total weight load on the ropes 55 is less; therefore, the anchoring of rope 55 can be satisfied with the use anchor clamp 90. As illustrated, anchor clamp 90 is generally “C”-shaped with inwardly turned first and second ends 91 and 92. First end 91 includes a fixed pointed head member 93 pointed inwardly while second end 92 is provided with a threaded rod 94 that terminates with another pointed head 95 directly opposite of first pointed head 93. A lever 96 extends through threaded rod 94 and is used to bring second pointed head 95 into close engagement with a stationary member such as a door jamb 14 shown in FIG. 9. Opposite ends of vertical portion 97 are proved with first and second opening 98 and 99. The purpose of these openings is to attach the anchor carabiners 57, as shown in FIG. 2. Kick plates 100K are provided on the outer portions to assist the “C” clamp in penetrating the wall around the door frame.
Referring now to FIG. 4, there is shown a plan view of the descent controller 65. As shown, the descent controller 65 comprises an upper plate 66 and lower plate 67 (not shown in this view) with a pair of friction cams 68, 69 sandwiched there between by a pair of bolts 61, 62. Upper cam 68 has a rope receiving groove 68A. Lower cam 69 includes a lever portion 70 extending from a portion thereof that is used for rotating lower cam 69 into and out of its locked/released positions. Lower cam 69 begins with rope receiving groove 69A at point 71, the size of this groove is constant to the point labeled 72. At this point, the rope groove tapers as shown at 72A. Upper cam 68 has a rope engaging groove 68A of uniform size while lower cam 69 has a rope receiving groove 69A that accommodates rope 55 up to approximately the point indicated by line 72 on the side of cam 69, from which point on, its decreases progressively to the point where it no longer allows rope 55 to pass therethrough. (See groove 72A in FIG. 5.) As the rope 55 is tightened in groove 72A, handle 70 rotates to the point where handle 70 moves in an upward position causing the rope to bind and stop moving between upper cam 68 and lower cam 69. Additionally, when it is desired to release descent controller 65, lever handle 70 is pushed downward, thus rotating second cam 69 to rotate to the point where rope 55 slides easily along upper cam 68 and lower cam 69 allowing the wearer to descend at a controlled rate of speed. Portable carry-on bag 50 is provided with 200 ft. of rescue rope which is approximately 11 mm in diameter. A superior handling rescue lifeline, kern mantle rope features a composite construction of nylon and polyester fibers. The rope 55 is torque-balanced to eliminate any spin during a rappel. The continuous filament polyester sheath is braided over a continuous nylon fiber core. This provides excellent handling and knot-holding characteristics, as well as rugged protection from abrasion and cutting. The polyester sheath provides added protection for ultra-violet light and from chemicals that are harmful to nylon. The polyester sheath also reduces the strength loss and additional weight that occurs when nylon absorbs water. It has over 5,000 lbs. of tensile strength.
FIG. 5 is a side elevational view taken along the plane 5-5 of FIG. 4 and illustrates grooves 68A, 69A and tapering groove 72A, it also illustrates the engagement of handle 70 with side plate 66 when descent controller 65 is in its locked position.
FIG. 6 is a plan view of the upper cam 68 per se.
FIG. 7 is a plan view of the lower cam 69 per se.
FIG. 8 is an illustration of the use of the equipment during the evacuation of a single person during an emergency situation. As shown, an evacuee 10 with a single harness 11 donned has exited through the broken window glass 12. The evacuee 10 is shown holding the descent controller 65 in his hand as he descends. Tarp 103 is shown covering as much as possible of the broken glass of the window 12 to prevent cutting of the evacuee or the rope line 55. As shown, rope 55 is connected to “C”-clamp 90 that has been securely fastened to door jamb 14. Once the evacuee 10 is ready to exit through window 12, he will throw portable carry-on bag 50 out the window 12, as shown in the lower portion of FIG. 9, where it will serve to stabilize the rope 55 as the evacuee descends.
FIG. 9 is another illustration of the equipment in use. In this view, a double harness 11D is in use. In this embodiment, there is only one descent controller 65 as in the other embodiment. The only difference is the use of the double harness 11D to accommodate the second evacuee and also the use of plural anchor straps 58 to accommodate the additional weight.
