DETAILED DESCRIPTION OF THE INVENTION
(11) This invention relates to a lightweight personal escape system worn and used by a fire fighter during an emergency situation. The system provides capability for a descent of approximately 50 feet without having to search for locations that provide basis for attachment of an escape rope. This lightweight system is worn by the fire fighter as an accessory that is securely attached to a belt. The system comprises a heat resistant outer pouch having a compartment for receiving and housing a lightweight specially shaped hook that is utilized as an escape hook and a heat shrink inner pouch. The outer pouch is composed of a heat resistant material. The inner heat shrink pouch houses a heat and abrasion resistant rope having a detachable device integrally associated therewith and being adapted to reduce the rate of descent of the escaping person.
(12) Generally stated, the invention of personal escape system and method, which would be utilized by a fire fighter when descending from a high-rise building broadly comprises: (i) a multi-attachment escape hook: (ii) a heat and abrasion resistant rope; (iii) a heat shrink internal or inner pouch; (iv) a heat resistant external or outer pouch; (v) wherein the device includes a descent control mechanism; and (vi) wherein the device is appointed to be attached to a belt or harness.
(13) The Fire Fighters Personal Escape System has applications in safety and preventative measures in the safety of fire fighters and other first response rescuers, including law enforcement and military personnel. Advantageously, the Fire Fighter's Personal Escape System can be utilized to save lives, while providing a lightweight safety device that can be effortlessly worn on the person without being cumbersome or bulky.
(14) The device has a lightweight escape hook preferably made from a high strength iron, which can support more than 6000 pounds. Optionally, the hook may be made from high strength titanium alloy material, which can support more than 6000 pounds. The hook is specially dimensioned with an opening of 2.125 to 3.5 inches at its widest point to fulfill multiple fastening methods. Advantageously, the hook has a size and shape especially well suited to fit about the radius of most radiators, which are located near a window used for escape purposes. The shape of the hook facilitates its use as a choker, and facilitates placement of a Halligan tool, or other firefighting hand tool, through the handle of the hook as a method to secure the hook to a wall. The sharp tip of the hook can make its own purchase point. For example, the tip can be driven into sheet rock, a wall, a chair, a mattress, or other penetrable object capable of acting as a support object. It doesn't have to be wrapped around something to provide an anchoring function. The anchor point options provided by the hook provide a significant advantage. A strong anchor is expeditiously effected, markedly enhancing the system's utility. The hook can be also used as a carabineerto put multiple pieces of hardware in combination with the system. For example, the hook can be thrown around the leg of a large bed, making a loop around the leg, to anchor the device before repelling from a window. In addition, preferably the Fire Fighter's Personal Escape System is bar coded or assigned serial numbers for accountability. In this manner, all parts of the system are bar coded for readily identifying the components of any given system. That is to say, the rope, inner pouch, outer pouch, and hook each are provided with an inter-related bar code unique to a fire fighter's individual escape system, so that one can readily identify each individual's systems' components.
(15) The rope is preferably composed of two portions, including an outer sheath and an inner core. The outer sheath of the rope is composed of a high strength abrasion resistant material, such as Kevlar aramid fiber, which exhibits a higher heat and ware resistance than nylon or polypropylene materials. Kevlar is commonly used in bulletproof vests. The inner core of the rope is preferably composed of a material having a high tensile strength, such as Vectran. The device comprises about 30 to 100 feet of rope, preferably comprises 40-50 feet of rope, and most preferably comprises 40 feet of rope. A length between 40-50 feet of rope is generally sufficient for most fire fighters to get out of harms way. The overall weight of the rope is up to 5 pounds, and preferably about 2 pounds, and is easy to carry as a personal escape device for a fire fighter. The rope is organized and laid in a manner similar to that of a parachute rope so that the rope is freely released from storage as needed by the fire fighter during an escape event.
(16) The organized rope is entirely contained in a pouch that is covered with a heat shrink material. Conveniently, this pouch containing the organized rope may be fashioned as a belt that is worn around the waist of a firefighter with attachment on a class I, II, or III harness. Preferably, the pouch is adapted to be attached to an existing belt or harness. Moreover, the outer pouch, which is adapted to receive and house the inner pouch and rope, is preferably attached to a hook pouch, adapted to receive and house the hook, thereby forming a unilateral or one-piece pouch arrangement. Optionally, the outer pouch and the hook pouch are two separate, discrete, pouches.
(17) The proximal end of the rope is attached to the hook. The hook may pass through a belay, a multiple aperture tab, or a friction generation element so that the friction generated at the rope facilitates a controlled descent of the fire fighter. The fire fighter reduces rope friction at the multiple aperture tab by moving the rope, or by squeezing the handle of the descender to increase the speed of the descent, thereby effecting a controlled descent.
(18) Key components of the Fire Fighter's Personal Escape System include, in combination, the components set forth below:
(19) 1. a specially shaped lightweight high strength hook designed to capture radiators, bedposts, pipes and other attachment objects;
(20) 2. the hook having a pointed sharp tip that serves to create an anchor or purchase point in sheet rock, a mattress or other penetrable anchor locations;
(21) 3. the hook having a closed aperture to be used as a choker or as means for using other fire fighter hardware in conjunction therewith, including a Halligan tool, in order to establish a secure attachment point;
(22) 4. the hook being attached to the proximal end of a strong lightweight heat resistant rope composed of a Kevlar aramid fiber outer jacket and a Vectran core, or other suitable materials;
(23) 5. the rope arranged as a set of parallel looped layers in a heat shrink inner pouch for easy snag-free one time delivery of the rope on demand during a fire fighters escape;
(24) 6. the distal end of the rope having a stopper knot to prevent the firefighter from going into free-fall;
(25) 7. the rope passing through a belay or friction generating element;
(26) 8. the inner pouch being placed in an outer pouch appointed to safely accommodate the inner pouch, and a further hook pouch being provided to house the lightweight hook having a pointed sharp tip, and said outer pouch and said hook pouch being further adapted to be attached to a belt worn by the fire fighter; and
(27) 9. the belay or friction device being attached to the belt associated with the outer pouch by a carabineer;
(28) 10. the belt being a class I, II, III harness. Class I harnesses include devices generally comprising a waist belt; Class II harnesses include devices generally comprising a waist belt and leg loops; and Class III harnesses include devices having a waist belt, leg loops and an upper body shoulder straps.
(29) whereby the fire fighter is equipped with a personal escape system that affords reliable attachment of the escape system to readily available objects that are commonly present within a building, allows controlled descent of the fire fighter using a friction device, and has means to defeat the friction device, to thereby provide for fast descent. The hook of the system also has a closed elliptical aperture for using (carrying) a Halligan tool or other fire fighting hardware to secure the hook to a structure (and can be used to attach other system hardware).
