Definitions
- This invention relates to the field of transporting and transferring payloads in a quick and efficient manner; more particularly to manual transport and transfer of humans especially in emergencies entailing constraints of time, safety, additional manpower and specialised equipment, among others.
- the commonly used transport/transfer systems and apparatus employed in non-combat environments include at least two or more hands (manpower), a stretcher or such other device that more often than not, occupies considerable space besides being unwieldy, to secure, transport and transfer the injured/sick.
- Professional rescuers such as fire-fighters, military personnel etc., undergo specialised and intensive training and discipline to handle emergency rescue operations with ad hoc kits and accoutrements to bundle- and-drag/package-and-move or lift the injured or deceased from one place to another.
- quality training and discipline is lacking in staff of civilian hospitals, due to economic, operational, among other reasons.
- the bundle- and-drag/package-and-move methods used by fire- fighters or military personnel serve mainly the purpose of moving/transporting the injured/deceased over a very short distance only, since it is neither feasible nor safe to drag a human over long distances especially over uneven, wet or untrodden terrain, in which case the only alternative is to physically carry the injured/deceased to the destination - which is a tiresome and tedious proposition and which entails the total engagement of at least one arm of the rescuer, besides engaging his focus to keep his balance and pace etc., which compromise the rescuers safety as well, in the incendiary/combat arena.
- an average human adult can at best carry one injured/deceased adult at a time and run/walk, which would at least double his time to cover the same distance, as without the load.
- the structure, shape, size and weight of an adult human renders him all the more unwieldy especially when his body is limp due to injury/death. This could mean each injured person requires one ad hoc, robust and willing rescuer, in an emergency - which (ratio of 1 : 1) is highly improbable in most emergency circumstances where damage to life and limb is rapid and severe.
- the aspect of being a four-wheeled stretcher greatly reduces its manoeuvrability and navigability as also the comfort accorded to the injured during transport on uneven terrain due to the rigid chassis that bears the payload.
- the relatively long time it would take to secure the injured with straps on to the stretcher is another disadvantage especially in view of the shortage of time and hands (manpower) during emergencies such as in the battle field or fire accidents.
- a further drawback is its relative infeasibility when the payload is to be airlifted.
- Another main object of this invention is to design, construct and develop a cost It is therefore the main object of this invention to provide for an efficient, cost-effective, portable, collapsible apparatus, system and method/s for simple and quick, single- handed, hands-free, manual simultaneous transport and transfer of multiple payloads including humans, with minimal effort, that is light and stow-able on the person of the rescuer.

- Each said element [2] or hollow cylindrical pipe has a transverse circular ridge (not shown in drawings) around the outer surface at its proximal end and another transverse circular ridge in its inner surface at its distal end just before the flange/collar such that each element [2] (except the 1 st or proximal element [3]) is permanently locked to the preceding element [2] of next higher diameter (by the said transverse circular ridges) thereby restricting its movement from coming free of the preceding element [2] of next higher diameter but allowing for its slide- able/telescopic/rotary movement within.
- the proximal ends of the said arms [1] are attached to Anchoring means [8].
- the said arms [1] converge toward their distal end where they meet and get attached to the means to reduce friction - being preferably a swivel-able caster or wheel [22], thereby forming a triangular stretcher.
- the joint where the distal ends of the said arms [1] meet with each other and with the said caster [22], is such that it allows for the necessary play/movement along the X and Y axes for the said two arms to be spliced/jointed at their proximal ends.
- Such joint is without limitation at least one pivot joint or a hinge joint or ball and socket joint or any combination of thereof, so as to facilitate the transfer, loading and unloading of the payload.
- the material that the said elements [2] are made of is, without limitation - metal (steel) or alloys or plastic or P VC, Fibre-plastic or reinforced plastic or combinations of such other material known in the art that is light and capable of withstanding the weight of the payload and makes a smooth surface that offers minimal friction during extension or collapse of the said elements [2].
- a relatively flexile component being means to bear, support and further cushion the payload, which is preferably (without limitation) a netting [14] made of light weight, and preferably all-weather durable material with the desired degree of elasticity such as but not limited to nylon, spliced with rubber or such other suitable material/s or combination/s thereof known in the art, wherein each end of every main/transverse strand of the net [14] is tied/secured to the said loop [7] attached to the said Ring [6] referred above, such that every main transverse strand connects one element [2] of a given arm [1] to the corresponding element [2] of another.
- a netting [14] made of light weight, and preferably all-weather durable material with the desired degree of elasticity such as but not limited to nylon, spliced with rubber or such other suitable material/s or combination/s thereof known in the art, wherein each end of every main/transverse strand of the net [14] is tied/secured to the said loop [7
- Each said main/transverse strand is further connected to adjacent strands by means of longitudinal strands so as to form a net [14] to effectively bear the weight of the payload.
- the said netting [14] so formed is in the form of a triangular narrowing hammock characterised by a structure that provides for the centre of gravity of the payload to rest rather toward the distal end of the said rigid arms [1], and further such that when the proximal ends of the said arms [1] (of the rigid component described above) are joined together or spliced and suspended (vertically) from the said proximal end, the payload (especially but not limited to human [23]) contained in the said netting [14] is not only snugly cocooned and secured from falling out, but is also not squeezed or crushed, while its overall posture is preserved intact,
- the said unit is further provided with a mechanism to automatically stretch out and automatically collapse by actuating the required mechanism
- the 1 st (proximal element [3]) of each arm [1] is connected directly or indirectly to a rotary device such as a motor [15] and/or a draw string/s [19] wound on a spindle [17] such that the rotating motion in a given direction of (at least) the second last element [2] causes the said second last element [2] to unscrew or unwind itself from the last (distal) element [4] and once the said second last element [2] unscrews itself from its succeeding/last element [4] and ceases to rotate, the third last element [2] unscrews itself from the said second last element [2] and so on until the first (proximal element [3]) of each arm unscrews itself from its succeeding element [2] thereby causing the collapsed arms [1] of the unit to stretch out.
- a rotary device such as a motor [15]
- the said unscrewing and screwing of elements [2] is effectively brought about due to the fact that on the one hand, the 1 st element [2] is freely swivel-able about its longitudinal axis at its proximal end wherein it is connected to the anchoring means [8] by a swivelling joint [12], which in turn is connected to the rotary device, and on the other hand the last or distal element [4] of each arm is nonrotary since it is fixed to the last or distal element [4] of the other arm and also to the head of a swivelling castor or wheel [22], and the stretching out and collapse is further brought about by the screw threads on the inner and outer ' surfaces of each element [2].

- the said flexible or resilient means [10] makes an preferably acute ( ⁇ 90 degrees) angle with the said Vertical arm [9] of the Anchoring means [8] so as to form a hook-like structure [1 1] to facilitate simple engagement of airlifting gear [24] or other gear or rope or knot, when the unit along with its payload is to be transported/transferred.
- the said anchoring means [8] is further provided with suitable mechanism known in the art to be locked to and unlocked from the said fastening means [21] such as by (without limitation) a press lock, (or push lock or a carter pin).
- the other end of the said flexible or resilient means [10] is further provided with a swivelling means [12] which in turn is permanently fixed to the upper end of the said first/proximal element [3] of each arm [1] such that when the said swivelling means [12] rotates, the said first/proximal element [3] also rotates.
- the said vertical arm [9] is further provided with a power source such as a battery which can be seated preferably within its hollow space and which is connected to the said motor [15].
- One or both of the said vertical arms [9] of the said anchoring means [8] is further provided with simple clamping or clipping means at the upper end such that the two arms [1] of the said rigid component can be spliced and clamped together by pushing one member of the said clipping/clamping means located on one of the said vertical arm [9] into/against another, wherein the said clipping/clamping means is without limitation a pipe clip or spring clamp, (e) A rotary means being, preferably but not limited to, (i) an electric motor [15] (preferably one for each arm) which is embedded in the said flexible or resilient means [10] and is connected to the said swivelling means [12], and (ii) Two draw-strings [19] wound (in opposite directions) around a spindle [17] which is coaxially connected to the said swivelling means [12], such that when one of the said draw-string [19] is pulled, the spindle [17] (and so the swivelling means [12

- the said Apparatus is triangular when stretched out, with the proximal end fastened/clung to the body of the rescuer through the Fastening means [21], transports a human [23] in a reclining posture/position while for instance being transported on ground, and can transfer the human [23] in a vertical position while for instance being air-lifted, being light, highly collapsible (when not in use), so as to be stowed on the person of a rescuer, by forming part of his personal gear/outfit and wherein more than one such units can be effectively engaged by a single rescuer simultaneously.
- METHOD/S OF OPERATING THE PREFERRED EMBODIMENT METHOD/S OF OPERATING THE PREFERRED EMBODIMENT:
- the rotary mechanism may be either a battery powered motor [15] or the manual draw-strings [19] wound around the spindle [17], embedded in the Flexible/resilient means [10] of the Anchoring means [8].
- the Rescuer is now ready to comfortably transport at least (without limitation) up to 4 payloads (e.g., humans [23]) on (without limitation) at least 4 units on his person.
- payloads e.g., humans [23]
- a single rescuer donning the said (collapsed) System and Apparatus arrives at the spot and executes steps (a), (b), (c) and (d) above wherein he chooses to either push the payload by engaging the Unit/s in the from (ahead of him) or pull the payload by engaging the Unit/s behind him; In case of unfamiliar terrain he may choose to pull the payload by engaging the Unit/s behind him.
- the rescuer executes the steps (a), (b), (c) and (d) above with the exception that the Unit is turned up-side down such that the caster [22] is not in touch with the ground and the distal elements [2] of the said Arms [1] are in contact with the ground/floor/stairs. This is to preclude a tangle of the caster [22] with the perpendicular phase of the stairs.
- the rescuer may choose to preferably pull the Unit with the payload up the flight of stairs either fastened to the Fastening-Apparatus [20] or by holding the proximal ends of the Unit and climbing up as shown in the drawing.
- the rescuer executes the steps (a), (b), (c) and (d) above, and may choose to preferably pull the Unit with the payload down the stairs either fastened to the Fastening- Apparatus [20] as shown in the drawings, or by holding the proximal ends of the Unit and climbing down.
- the rescuer may adjust the length of the Arms [1] by actuating the rotary means to make the desired angle of the Unit with the ground, such that the payload does not touch the terrain while being transported.
- the rescuer joins/splices the proximal ends of both arms [1] of the Unit by engaging the pipe clip or spring clamp such that the payload is secured and encapsulated by the netting [14] that enshrouds and cocoons it snugly and also by the said arms [1] that are joined together that provide rigidity and support to the capsule to keep the payload from buckling/deforming.
- This obviates the need to additionally secure the payload with straps or other such securing gear, since the said netting [14] snugly grips the payload and the said Arms [1] act as the mainstay to lend support and preserve the posture/shape of the payload.
- the rescuer then fastens the airlifting gear [24] such as a rope to the spliced Anchoring means [8] that form a hook-like structure [11] by making an acute angle with the arms [1], by means of a slipknot or other such knot.
- the payload along with the unit is now suspended vertically and can be drawn up/down from the aircraft [13].
- a simple method to unload a given payload would include without limitation, while the unit is not vertical in position, moving the proximal end of one of the said arms [1] of the said rigid component away from the other along the vertical axis/plane, such that the payload gently rolls over, out of the said unit.
- This is made possible by either a double hinge joint/pivot joint (one perpendicular to the other) or a ball and socket joint or any combination thereof.
- the said unit In case of an injured (e.g., human [23]/animal) payload, the said unit is placed on the surface on to which it is to be transferred, and then the netting [14] is gently pulled from underneath the payload along with the said rigid arms [1] along the direction of the longitudinal strands of the netting [14] toward the distal end, while gently lifting the corresponding sections of the payload.
- an injured e.g., human [23]/animal

Description
A portable, collapsible apparatus for hands-free transport of multiple payloads including humans, that is stow-able on the person of the rescuer, the system and methods thereof. Field of the invention
This invention relates to the field of transporting and transferring payloads in a quick and efficient manner; more particularly to manual transport and transfer of humans especially in emergencies entailing constraints of time, safety, additional manpower and specialised equipment, among others.
Background of the invention
While sophisticated equipment have evolved over time for the transport of human paraphernalia as well as humans itself, challenges posed by emergency situations with constraints as to time, safety, additional manpower and specialized equipment, etc., continue to daunt man to this day. The need for additional emergency-help (additional manpower) and supporting equipment to transport an injured person from an accident spot, or battle field, or even from an ambulance into the hospital ward or operation theatre, when time is short, are cases in point. Statistics indicate that the lack of additional help/manpower and/or the lack of transport equipment during crucial moments have proven fatal to the critically injured. The commonly used transport/transfer systems and apparatus employed in non-combat environments include at least two or more hands (manpower), a stretcher or such other device that more often than not, occupies considerable space besides being unwieldy, to secure, transport and transfer the injured/sick. Professional rescuers such as fire-fighters, military personnel etc., undergo specialised and intensive training and discipline to handle emergency rescue operations with ad hoc kits and accoutrements to bundle- and-drag/package-and-move or lift the injured or deceased from one place to another. Unfortunately such quality training and discipline is lacking in staff of civilian hospitals, due to economic, operational, among other reasons. Moreover, the bundle- and-drag/package-and-move methods used by fire- fighters or military personnel serve mainly the purpose of moving/transporting the injured/deceased over a very short distance only, since it is neither feasible nor safe to drag a human over long distances especially over uneven, wet or untrodden terrain, in which case the only alternative is to physically carry the injured/deceased to the destination - which is a tiresome and tedious proposition and which entails the total engagement of at least one arm of the
rescuer, besides engaging his focus to keep his balance and pace etc., which compromise the rescuers safety as well, in the incendiary/combat arena. During a rescue operation, an average human adult can at best carry one injured/deceased adult at a time and run/walk, which would at least double his time to cover the same distance, as without the load. Besides, the structure, shape, size and weight of an adult human renders him all the more unwieldy especially when his body is limp due to injury/death. This could mean each injured person requires one ad hoc, robust and willing rescuer, in an emergency - which (ratio of 1 : 1) is highly improbable in most emergency circumstances where damage to life and limb is rapid and severe. However, with the fast pace and complexities of civilised life, it is not uncommon to meet situations of emergency, both in military and civil life, wherein an acute shortage of time, equipment and additional hands (manpower), tell on the quality of the operation to rescue the critically injured. Emergency medical transport equipment available today ranges from simple, collapsible quadrangle with 4-wheels or at least 2-wheels, to the sophisticated, 'all found' contraptions that provide for other life saving medical equipment snugly fitted together. However, even the simplest of medical emergency transport equipment available today, such as portable and collapsible stretchers, chairs etc., occupy considerable space and mass and therefore cannot be stowed on the person of a rescuer all the time and therefore need to be first transported to the spot of need, in order to carryout the transport of the injured/deceased, which entails severe time delays and logistical and operational lapses/risks. Another drawback in todays rescue methods including the bundle-and- drag/package-and-move methods is, the time and effort it takes in strapping or otherwise securing the subject (human) before being transported/moved.
Another drawback in most of today's emergency medical transport equipment (however much collapsible they may be) is their shape, size, weight, dimension and complexity that render them unwieldy for a single man to handle, and which gets further compounded when the injured are to be air-lifted, since ground equipment are incompatible with airlifting gear. In US20120007340 wherein an attempt to stow a collapsible wheeled stretcher on the person of the rescuer has been made with some success, the said invention cannot be engaged hands-free while transporting an injured person. Still further, the aspect of being a four-wheeled stretcher greatly reduces its manoeuvrability and navigability as also the comfort accorded to the injured during transport on uneven terrain due to the rigid chassis that bears the payload. Besides, the
relatively long time it would take to secure the injured with straps on to the stretcher is another disadvantage especially in view of the shortage of time and hands (manpower) during emergencies such as in the battle field or fire accidents. A further drawback is its relative infeasibility when the payload is to be airlifted. In US8087112 too, wherein an attempt to stow a collapsible stretcher on the person of the rescuer has been made with some success, and the rescuer is able to transport the payload hands- free, (a) the time it would take to assemble and bring the collapsed stretcher into operation especially due to the relatively complex and elaborate assembly process/procedure, and still further (b) the time it would take to strap-up the injured on to the stretcher are disadvantageous especially in combat/incendiary/disaster prone arena, that entail acute shortage of time. Other significant disadvantages of the said invention would include, (c) the considerable space it would occupy even when collapsed owing to its design and structure, besides being that much (d) cumbersome and heavier on the rescuer to carry as dead weight and would therefore be (e) undesirable as an item to form part of the regular outfit for a soldier. Besides, the assembly and disassembly/collapse of the said invention as described, (f) cannot be easily automated owing to the complexity of its structure/design, and would therefore (g) call for ad hoc training in advance for the rescuer before he can employ the said invention which render it cost prohibitive for large scale implementation.
There is therefore an urgent as well as long felt need for an cost-effective, portable, collapsible apparatus, system and method/s for simple and quick, single-handed, hands-free, manual simultaneous transport and transfer of multiple payloads including humans, with minimal effort, that is light and stow-able on the person of the rescuer. Objects of the invention
It is therefore the main object of this invention to apply the 'quarter wheel concept', propounded by this inventor, to smoothly, seamlessly and almost effortlessly shift/transfer the load from a flat/punctured wheel of a vehicle, on to another wheel (of the same or marginally different radius) by interposing 'the quarter of a small wheel' which is melded to the hooping of and contiguous with the latter'.
Another main object of this invention is to design, construct and develop a cost It is therefore the main object of this invention to provide for an efficient, cost-effective, portable, collapsible apparatus, system and method/s for simple and quick, single- handed, hands-free, manual simultaneous transport and transfer of multiple payloads
including humans, with minimal effort, that is light and stow-able on the person of the rescuer.
It is another main object of this invention to provide for a transport and transfer apparatus and system so designed and structured that it is unobtrusive and can form part of the rescuers' standard kit or PLCE (Personal Load Carrying Equipment) wherein the payload can be carried and transported with minimal effort and stress to the rescuer and the rescued.
It is another main object of this invention to provide for an economical, lightweight and highly collapsible single-handedly operable alternative to the present day unwieldy quadrangular stretcher (with 4-wheels or at least 2-wheels), which demands two or more persons to engage in a typical emergency rescue operation.
It is another main object of this invention to provide for a device that is suitable for medical transport on the ground, as well as compatible for instantly airlifting the injured/deceased (subject), without the need to strap or otherwise additionally secure the subject before airlifting.
It is another main object of this invention to provide for an emergency medical transportation apparatus whereby a rescuer can singlehandedly load the injured on to it and transport him with minimal physical effort and in a very short time, even over relatively uneven terrain, especially as an alternative to the 'Bundle-and- Drag'/'Package and Move' method which involves strapping and dragging carrying the subject which is relatively time consuming and cumbersome.
It is another main object of this invention to provide for a handy, triangular hauling apparatus in the form of a stretcher that preferably runs/rolls on one wheel, characterized by superior manoeuvrability, collapsibility, stowability, automated stretch-out and collapse operations, that transports a human in a reclining posture, and that forms part of a rescuers standard outfit/gear.
It is a further object of this invention to provide for an emergency medical transportation apparatus to manually transport a human/s by either pulling or pushing the payload, at the rescuer's option especially in terrains such as but not limited to foresty or rugged terrains or while traversing or fording water bodies or to effortlessly mount the payload on the rescuer's person and transport it in a recumbent position. It is a further object of this invention to provide for an an emergency medical transportation apparatus, system and methods to traverse water bodies that are too deep to wade/ford, whereby the unit fitted with buoying means can be made to float
on the surface of the water whereby the rescuer can drag the said laden unit along, while swimming across the water.
It is a further object of this invention to provide for an emergency medical transportation apparatus, system and methods whereby a single rescuer can simultaneously transport more than one units of payload (e.g., injured humans) with considerable ease and efficiency.
It is a further object of this invention to provide for further adaptations of the emergency medical transportation apparatus, to suit other needs of the soldier/rescuer such as but not limited to climbing/scaling, rappelling, mounting and positioning surveillance devices such as cameras/scanners, or other communication systems etc., Statement and summary of the invention

I EMBODIMENT - 1
According to this (preferred) embodiment, there is provided an efficient, cost- effective, portable, collapsible apparatus, system and method/s for simple and quick, single-handed, hands-free, manual, simultaneous transport and transfer of multiple payloads including humans [23], with minimal effort, comprising;
1. A plurality of Units, each unit of the system comprising;
(a) A relatively rigid component, being a highly collapsible system of at least two arms [1] that supports a relatively flexible component - being the netting [14] described hereinbelow; each arm [1] comprises a plurality of (about 10 - 11) elements [2] that can be stretched out, or collapsed to occupy minimal space; Each said element [2] of the arm [1] being a hollow cylindrical pipe about 8 inches in (total) length, and wherein one (distal) end is flanged into a Collar about 0.5 inches in length and with an outer diameter (of about 0.05 inches) greater than the diameter of the rest of the respective element [2]. The arrangement of the said elements [2] is telescoping such that the last element [4] (at the distal end of a given arm) has the smallest diameter and snugly fits into the lumen of the preceding element [2] which has a marginally greater diameter, and the first (or proximal) element [3] of an arm [1] has the largest diameter (without limitation) of about 1.25 inches. The said collar bears a transverse constriction [5] of about 0.25 inches in length and 0.05 inches in depth) on its outer surface to accommodate a Ring [6] that rotates freely around but is restricted within the said transverse constriction [5]. The said Ring [6] bears on its outer edge, a Loop [7] of about 0.2 inch diameter. Each said element [2] or hollow cylindrical pipe bears screw threads (not shown in
drawings), both on its outer surface and its inner surface along its length excepting the said collar. The 'lead' of the said threads is preferably wide (about 4 inches, without limitation) so as to enable greater degree of telescopic extension and collapse per rotation. Each said element [2] or hollow cylindrical pipe has a transverse circular ridge (not shown in drawings) around the outer surface at its proximal end and another transverse circular ridge in its inner surface at its distal end just before the flange/collar such that each element [2] (except the 1st or proximal element [3]) is permanently locked to the preceding element [2] of next higher diameter (by the said transverse circular ridges) thereby restricting its movement from coming free of the preceding element [2] of next higher diameter but allowing for its slide- able/telescopic/rotary movement within.
The proximal ends of the said arms [1] are attached to Anchoring means [8]. The said arms [1] converge toward their distal end where they meet and get attached to the means to reduce friction - being preferably a swivel-able caster or wheel [22], thereby forming a triangular stretcher. The joint where the distal ends of the said arms [1] meet with each other and with the said caster [22], is such that it allows for the necessary play/movement along the X and Y axes for the said two arms to be spliced/jointed at their proximal ends. Such joint is without limitation at least one pivot joint or a hinge joint or ball and socket joint or any combination of thereof, so as to facilitate the transfer, loading and unloading of the payload.
The material that the said elements [2] are made of is, without limitation - metal (steel) or alloys or plastic or P VC, Fibre-plastic or reinforced plastic or combinations of such other material known in the art that is light and capable of withstanding the weight of the payload and makes a smooth surface that offers minimal friction during extension or collapse of the said elements [2]. (b) A relatively flexile component, being means to bear, support and further cushion the payload, which is preferably (without limitation) a netting [14] made of light weight, and preferably all-weather durable material with the desired degree of elasticity such as but not limited to nylon, spliced with rubber or such other suitable material/s or combination/s thereof known in the art, wherein each end of every main/transverse strand of the net [14] is tied/secured to the said loop [7] attached to the said Ring [6] referred above,
such that every main transverse strand connects one element [2] of a given arm [1] to the corresponding element [2] of another. Each said main/transverse strand is further connected to adjacent strands by means of longitudinal strands so as to form a net [14] to effectively bear the weight of the payload. The said netting [14] so formed is in the form of a triangular narrowing hammock characterised by a structure that provides for the centre of gravity of the payload to rest rather toward the distal end of the said rigid arms [1], and further such that when the proximal ends of the said arms [1] (of the rigid component described above) are joined together or spliced and suspended (vertically) from the said proximal end, the payload (especially but not limited to human [23]) contained in the said netting [14] is not only snugly cocooned and secured from falling out, but is also not squeezed or crushed, while its overall posture is preserved intact,
(c) The said unit is further provided with a mechanism to automatically stretch out and automatically collapse by actuating the required mechanism wherein, The 1st (proximal element [3]) of each arm [1] is connected directly or indirectly to a rotary device such as a motor [15] and/or a draw string/s [19] wound on a spindle [17] such that the rotating motion in a given direction of (at least) the second last element [2] causes the said second last element [2] to unscrew or unwind itself from the last (distal) element [4] and once the said second last element [2] unscrews itself from its succeeding/last element [4] and ceases to rotate, the third last element [2] unscrews itself from the said second last element [2] and so on until the first (proximal element [3]) of each arm unscrews itself from its succeeding element [2] thereby causing the collapsed arms [1] of the unit to stretch out. Rotation caused by the said rotary device in the opposite direction will cause the stretched out unit to collapse as each element [2] screws itself into the lumen of its preceding element [2] until all elements [2] enter the lumen of the said first (proximal) element [3]. The said unscrewing and screwing of elements [2] is effectively brought about due to the fact that on the one hand, the 1st element [2] is freely swivel-able about its longitudinal axis at its proximal end wherein it is connected to the anchoring means [8] by a swivelling joint [12], which in turn is connected to the rotary device, and on the other hand the last or distal element [4] of each arm is nonrotary since it is fixed to the last or distal element [4] of the other arm and also
to the head of a swivelling castor or wheel [22], and the stretching out and collapse is further brought about by the screw threads on the inner and outer ' surfaces of each element [2]. As a substitute or alternative to the powered rotary device or motor [15] (to meet situations such as when the power source or battery is spent/flat etc.,) two draw-strings [19] are also wound around a spindle [17] connected to the said swivelling means [12] which in turn is connected to the proximal end of each 1st proximal element [3] such that when one of the said draw-string [19] is manually pulled, it unwinds to rotate the spindle [17] and in turn rotates the said 1st proximal element/s [3] in a given direction; and like wise when the other draw-string [19] is pulled it causes rotation of the spindle [17], the said swivelling means [12] and the said 1st proximal elements [3] in the opposite direction, thereby bringing about the stretching out and collapse of the arms [1] of the unit. The said spindle [17] is coaxially placed just behind the swivelling means [12] and is connected to it through a hollow cylindrical tube [18] which can disengage and engage the said swivelling means [12] when a draw-string [19] is to be pulled. One end of each of the said draw strings [19] (wound in opposite directions) is permanently fixed to the said spindle [17] while the other end of each drawstring [19] is free to be pulled/drawn. The shaft [16] of the motor [15] that connects the swivelling means [12] runs through the said hollow cylindrical tube [18] such that the motor [15] engages the said swivelling means [12], without engaging the said spindle [17].
(d) Anchoring means [8] provided at one (upper/proximal) end of the said relatively rigid component, that aid in anchorage of the said unit (in)to the Fastening means [21] of the Fastening-apparatus [20]; - comprising (a) a vertical arm [9] - being a cylinder or cylindrical polygon or polyhedron made of light and strong material - that fits into a fastening means [21] or hole or mortise; (b) a flexible or resilient means [10] that connects the upper end of the said vertical arm [9] to the said first/proximal element [3] of a given arm [1] (rigid component) and allows for vertical, horizontal play/movement of the said arm [1] - being made up of either a cylindrical piece of (without limitation) rubber or such other flexible resilient material optionally reinforced/supported with metal wire, or a metal spring or such other material or structure that can withstand the stress caused when the payload is
pulled/pushed and that can absorb the shock caused due to the walking/running/movement of the rescuer while the payload is pulled/pushed. The said flexible or resilient means [10] makes an preferably acute (< 90 degrees) angle with the said Vertical arm [9] of the Anchoring means [8] so as to form a hook-like structure [1 1] to facilitate simple engagement of airlifting gear [24] or other gear or rope or knot, when the unit along with its payload is to be transported/transferred. The said anchoring means [8] is further provided with suitable mechanism known in the art to be locked to and unlocked from the said fastening means [21] such as by (without limitation) a press lock, (or push lock or a carter pin). The other end of the said flexible or resilient means [10] is further provided with a swivelling means [12] which in turn is permanently fixed to the upper end of the said first/proximal element [3] of each arm [1] such that when the said swivelling means [12] rotates, the said first/proximal element [3] also rotates. The said vertical arm [9] is further provided with a power source such as a battery which can be seated preferably within its hollow space and which is connected to the said motor [15]. One or both of the said vertical arms [9] of the said anchoring means [8] is further provided with simple clamping or clipping means at the upper end such that the two arms [1] of the said rigid component can be spliced and clamped together by pushing one member of the said clipping/clamping means located on one of the said vertical arm [9] into/against another, wherein the said clipping/clamping means is without limitation a pipe clip or spring clamp, (e) A rotary means being, preferably but not limited to, (i) an electric motor [15] (preferably one for each arm) which is embedded in the said flexible or resilient means [10] and is connected to the said swivelling means [12], and (ii) Two draw-strings [19] wound (in opposite directions) around a spindle [17] which is coaxially connected to the said swivelling means [12], such that when one of the said draw-string [19] is pulled, the spindle [17] (and so the swivelling means [12]) rotates in a given direction to cause the elements [2] of the respective arm [1] to unwind and stretch out, and when the other drawstring [19] is pulled, the spindle [17] (and so the swivelling means [12]) rotates in the opposite direction to cause the elements [2] of the respective arm [1] to wind and collapse. Both rotary means (i) and (ii) are embedded within the flexible/resilient means [10] as shown in the drawings. The means to
actuate the motor [15], being a switch (not shown in the drawings) is also located on the said flexible/resilient means [10].
(f) Means to minimise friction while in use/motion, provided at another (lower/distal) end of the said relatively rigid component - being preferably a single swivelling caster or wheel [22], at the junction where the said two arms [1] meet.
2. Fastening-apparatus [20] for stowing, carrying and anchoring/cantilevering of the said (collapsed as well as stretched) components 1(a), 1(b), 1(c), 1(d), 1(e) and 1(f) above, on the outfit/gear/person of a rescuer comprising; *
(a) Means that form part of the outfit/gear of a rescuer characterized by such structure, shape and design that firmly and snugly fit on his person so as to allow for free movement of especially his arms and legs, and which also bear the Fastening means [21], - being, a belt, or a system of belts or straps, with the necessary padding to absorb the shock and stress when the payload is pulled/pushed, that can be firmly fastened, strapped or buckled around (but not limited to) the waist and/or shoulder and/or upper chest or other part of the person of the rescuer;
(b) Fastening means [21], to which the said Anchoring means [8] get fastened, characterised by a structure shape and design so as to allow for engagement and disengagement of the said Anchoring means [8] by actuating a mechanism for the purpose - being a set of holes or mortises into which the vertical arm [9] of the said Anchoring means [8] are inserted and locked by a locking means such as (without limitation) a press lock or push lock and which can be unlocked and removed from the said hole/mortise of the Fastening-apparatus [20] by the rescuer.
Wherein the said Apparatus is triangular when stretched out, with the proximal end fastened/clung to the body of the rescuer through the Fastening means [21], transports a human [23] in a reclining posture/position while for instance being transported on ground, and can transfer the human [23] in a vertical position while for instance being air-lifted, being light, highly collapsible (when not in use), so as to be stowed on the person of a rescuer, by forming part of his personal gear/outfit and wherein more than one such units can be effectively engaged by a single rescuer simultaneously.
METHOD/S OF OPERATING THE PREFERRED EMBODIMENT:
In the interest of brevity, sample situations and terrains have been indicated herein without limitation to the scope and extent of this invention.
1. RESCUE AND TRANSPORT ON EVEN GROUND
In order to transport injured (human/s [23] on animal/s) a single rescuer donning the said (collapsed) System and Apparatus arrives at the spot and;
(a) Turns on/actuates the rotary mechanism to stretch-out at least 1, 2, 3 or 4 units as required. The rotary mechanism may be either a battery powered motor [15] or the manual draw-strings [19] wound around the spindle [17], embedded in the Flexible/resilient means [10] of the Anchoring means [8].
(b) Once the units are stretched out, they are disengaged from the Fastening- means [21] of the Fastening apparatus [20] by unlocking the Anchoring means [8] from the Fastening means [21] and lays the stretched units on the ground. Each injured human [23]/animal is laid on the said Unit with his head towards the Anchoring means/proximal end of the Unit.
(c) In case there are additional hands (manpower) available, the injured can be laid on the Unit/s without disengaging them from the Fastening-Apparatus [20], thereby bypassing step (b) above.
(d) When the injured are laid on the respective Units, the said Units are held by the Anchoring means [8] at the proximal ends and fastened to the fastening means [21] in the Fastening- Apparatus [20] on the person of the Rescuer.
(e) The Rescuer is now ready to comfortably transport at least (without limitation) up to 4 payloads (e.g., humans [23]) on (without limitation) at least 4 units on his person.
2. RESCUE AND TRANSPORT ON UNEVEN TERRAIN
In order to transport the injured (e.g., human [23] or animal) a single rescuer donning the said (collapsed) System and Apparatus arrives at the spot and executes steps (a), (b), (c) and (d) above wherein he chooses to either push the payload by engaging the Unit/s in the from (ahead of him) or pull the payload by engaging the Unit/s behind him; In case of unfamiliar terrain he may choose to pull the payload by engaging the Unit/s behind him.
3. RESCUE AND TRANSPORT OVER A FLIGHT OF STAIRS
An example of transporting a human [23] on uneven terrain such as a staircase is (without limitation to the scope and extent of this invention) shown in the drawings wherein;
(a) WHILE ASCENDING A FLIGHT OF STAIRS, the rescuer executes the steps (a), (b), (c) and (d) above with the exception that the Unit is turned up-side down such that the caster [22] is not in touch with the ground and the distal elements [2] of the said Arms [1] are in contact with the ground/floor/stairs. This is to preclude a tangle of the caster [22] with the perpendicular phase of the stairs. The rescuer may choose to preferably pull the Unit with the payload up the flight of stairs either fastened to the Fastening-Apparatus [20] or by holding the proximal ends of the Unit and climbing up as shown in the drawing.
(b) WHILE DESCENDING A FLIGHT OF STAIRS, the rescuer executes the steps (a), (b), (c) and (d) above, and may choose to preferably pull the Unit with the payload down the stairs either fastened to the Fastening- Apparatus [20] as shown in the drawings, or by holding the proximal ends of the Unit and climbing down.
The rescuer may adjust the length of the Arms [1] by actuating the rotary means to make the desired angle of the Unit with the ground, such that the payload does not touch the terrain while being transported.
RESCUE AND TRANSFER BY AIR-LIFTING:
After steps (a), (b), (c), (d) and (e) above, once the payload (e.g., human [23]) is brought to the spot from where it is to be air lifted,
(f) The rescuer disengages the Anchoring means [8] from the Fastening means [21] of the Fastening- Apparatus [20],
(g) The rescuer joins/splices the proximal ends of both arms [1] of the Unit by engaging the pipe clip or spring clamp such that the payload is secured and encapsulated by the netting [14] that enshrouds and cocoons it snugly and also by the said arms [1] that are joined together that provide rigidity and support to the capsule to keep the payload from buckling/deforming. This obviates the need to additionally secure the payload with straps or other such securing gear, since the said netting [14] snugly grips the payload and the said Arms [1] act as the mainstay to lend support and preserve the posture/shape of the payload.
(h) The rescuer then fastens the airlifting gear [24] such as a rope to the spliced Anchoring means [8] that form a hook-like structure [11] by making an acute angle with the arms [1], by means of a slipknot or other such knot. The payload along with the unit is now suspended vertically and can be drawn up/down from the aircraft [13].
UNLOADING THE PAYLOAD:
A simple method to unload a given payload would include without limitation, while the unit is not vertical in position, moving the proximal end of one of the said arms [1] of the said rigid component away from the other along the vertical axis/plane, such that the payload gently rolls over, out of the said unit. This is made possible by either a double hinge joint/pivot joint (one perpendicular to the other) or a ball and socket joint or any combination thereof. In case of an injured (e.g., human [23]/animal) payload, the said unit is placed on the surface on to which it is to be transferred, and then the netting [14] is gently pulled from underneath the payload along with the said rigid arms [1] along the direction of the longitudinal strands of the netting [14] toward the distal end, while gently lifting the corresponding sections of the payload.
FURTHER ADAPTATION FOR OTHER USES:
This invention anticipates further adaptations of the said system and apparatus to suit specific and varied needs of the soldier/rescuer such as but not limited to be used (a) as climbing/scaling/rappelling gear, (b) as towing gear, (c) for mounting and positing surveillance devices such as cameras/scanners or other communication systems etc.,
II EMBODIMENT - 2
This embodiment is a stripped/bare cost-effective version similar to
Embodiment-I described above except the following distinguishing aspects;
(a) The elements [2] of the Arms [1] do not carry screw threads either inside (inner lining/lumen) or outside (outer surface).
(b) The Anchoring means [8] does not contain any automatic mechanism for stretching out or collapsing the said elements [2].
(c) The process of stretching out and collapsing is therefore manual whereby the rescuer physically pulls/extends out each element [2] to stretch out the
arms [1] and physically pushes/collapses each element [2] to collapse the arms [1].
Ill EMBODIMENT - 3
This embodiment is similar to Embodiment-I hereabove, except the following distinguishing aspects wherein, the said relatively flexile component referred to in 1(b) of Embodiment I is further provided with;
(i) a 'Substructure' [26, 27] to support the payload in order to prevent it from buckling, wherein, the said substructure comprises a plurality of members [25] which are collapsibly fastned one to another such that the maximum swing/pivotal/rotation about a given joint is (about) 180 degrees and suspended from the said arms [1] either by means of the transverse strands of the said netting or by means of rods (of hard plastic, metal or PVC or other suitable material known in the art) or by a combination of the two, whereby, when stretched out under the weight of the payload [23, 35], the said members [25] of the substructure [26, 27] form a plain supporting surface; and wherein the said flexile component [14] is attached/secured to the said members [25] such that they do not hinder, hamper or tangle when the said elements [2] rotate, collapse or stretch out, but stretch out and collapses in conjunction with the said elements [2];
(ii) And wherein, the said members are 'Slats' [25] or such other flat and preferably rectangular structures made of light weight material such as (but not limited to) Plastic, PVC, Aluminium or other metals or alloys or such combination of materials known in the art such as but not limited to leather Slats provided with metallic hinges, which provide the necessary rigidity and strength to bear a given class/weight/size of payload. Each slat [25] has a rather flat rectangular surface wherein, one (anterior) side of which (called the Male-end) is provided with a hinge-knuckle, bearing Pins [28] on either side of the said knuckle, and the other (posterior) side of which (called the Female-end) is provided with knuckles bearing holes [29] to accommodate the said pins of the Male-end of another slat. The thichness/hight of the slat [25] which equals the diameter of the said knuckles is (without limitation) about 2.5 - 5 mm. Each slat [25] is further provided with an 'Abutment cum Stop structure' [32] which restricts the rotational/pivoting/swing angle of one slat with respect to the other, to a
maximum of 180 degrees such that when the said slats [25] of the substructure [27] are hinged together and stretched out, they form a flat surface which does not buckle under the weight of the payload, wherein the said Abutment cum Stop structure [32] is an extension of the dorsal surface of the slat [25], in the form a strong plate or strip which extends (without limitation to) about 5mm - 15mm, beyond the said Knuckles [29] at its Female-end, so as to restrict and arrest the swing/rotation/pivotal of the Male-end of another slat which is hinged to it, to a maximum of 180 degrees. Each slat is fastned/hinged to another, such that the Male-end of one slat [25] is fastened/hinged to the Female-end of another [25] and further such that the dorsal side of one slat is in phase with the ventral side of the other slat to which it is fastned/hinged. Each slat is further provided with fastening means [31] so as(a) to be fastened to the said relatively flexible component (or the said netting [14]) or (b) to be directly suspended from the said arms [1] by means of rigid rods extending from the Loops [7] or Rings [6] therein, wherein, the said fastening means is a system of rings [31] through which the preferably transverse strands of the said net [14] or the said rods pass such that when the said arms [1] of a unit (and consequently the said netting [14]) stretch out, the said slats [25] are also forced to stretch out to form a flat substrutre [27]. The said Rings [31] are attached to the slats [25] such that one slat bearing the said rings on its dorsal side is fastned/hinged to another slat which bears the said rings on its ventral side whereby all the said rings[31] in a given substructure are on its ventral side.
There are preferably (without limitation) about 6 - 8 slats [25] in a unit, forming the said substructure that corresponds to preferably the 3rd through 8 elements [2] of the arms [1] wherein, each slat [25] is preferably (but not limited to) about 5 - 8 inches in width and either square or rectangular. Each slat is further linked to its adjescent slat by a suitably mild resilience or elastic means [33] which tend to corrugate and collapse the said slats especially when no payload is laid on the said substructure whereby, when the unladen unit collapses, the said members/slats [25] of the substructure [26] also collapse, wherein "the said resilience/elastic means [33] are (without limitation) elastic bands [33] or springs fastned preferably at one
end to the anterio-lateral side of one slat [25] and at the other end to the posterior-lateral side of the other slat [25] to which it is fastned/hinged. Optionally, the last slat at the distal end is 'L' shaped (not shown in the drawings) in order to prevent the payload [23, 35] from slipping/sliding downward especially when the payload is transported in a reclining / recumbent or vertical position.
(iii) Optionally, the said substructure [26, 27] is further provided with Detachable
Unloading gear [34] wherein, at least one broad strap with tapering ends [34], made of light weight flexible and durable material such as but not limited to Nylon, Polyester, leather, PVC or such other suitable material or fabric known in the art to be suitable to bear the weight of a given class/mass/size of payload, is velcroed to a slat/s of the said substructure [26, 27], wherin the central broad part of the said strap is preferably but not limited to about 6 inches in width and about 20 - 25 inches in length and the narrow/tapering part is about 2 inches in width and about 15 inches long on either side, provided with suitable fasteners such as but not limited to buckles or tucktite fasteners (not shown in the drawings), which facilitate quick and efficient unloading or offloading the payload from the unit whereby, at the time of unloading the two narrow ends of the said unloading gear [34] are fastned/buckled together and lifted to remove the payload out of the unit. Since the ventral side of the said Unloading gear [34] is velcroed to the slat over a small area of 1 to 2 square inches, it is simple and easy to detatch/disengage the Velcro from the slat as well as to fix it back onto the slat before loading the unit again.
(iv) Optionally, pneumatic or other buoying means may be incorporated with or fastened to the arms and/or netting so as to keep the payload afloat while traversing or fording water
METHOD OF TRANSPORT OF HUMAN OR OTHER PAYLOAD ACROSS
WATER, FORESTY OR RUGGED TERRAIN USING EMBODIMENT 3:
In order to transport injured (human/s [23, 35] on animal/s) a single rescuer donning the said (collapsed) System and Apparatus referred to in Embodiment #
3, arrives at the spot and;
(a) Turns on/actuates the rotary mechanism to stretch-out at least 1, 2, 3 or 4 units as required. The rotary mechanism may be either a battery powered
motor [15] or the manual draw-strings [19] wound around the spindle [17], embedded in the Flexible/resilient means [10] of the Anchoring means [8].
(b) once a Unit is stretched out, it is disengaged from the Fastening-means
[21] of the Fastening apparatus [20] by unlocking the Anchoring means [8] from the Fastening means [21]. The rescuer lays the stretched unit on the ground or water (afloat due to the pneumatic or buoying means). The injured human [23]/animal is laid on the said Unit with his head towards the Anchoring means/proximal end of the Unit.
(c) In case there are additional hands (manpower) available, the injured can be laid on the Unit/s without disengaging them from the Fastening-Apparatus [20], thereby bypassing step (b) above.
(d) When the human or such other payload is laid on the unit comprising the stretched out substructure [27], its arms [1] are spliced/joined so as to cocoon the payload within the netting [14] and between the arms [1] and the substructure [27], and the proximal end of the unit is lifted upwards drawing the distal end of the unit bearing the swivel-able caster/wheel [22] in contact with the ground, closer to the rescuer's body whereby the angle made by the arms if the unit with the floor is increased to about 30 -45 degrees, such that the region of the substructure [27] corresponding to the midsection of the payload [35] rests on the shoulder, (or such part of the body on which to balance the laden unit), of the rescuer.
(e) Once the midsection of the payload [35] rests on the shoulder (or such part of the body on which to balance the laden unit) of the rescuer, which plays the role of a fulcrum, the proximal end [3] of the unit is pulled downward about the said fulcrum, thereby lifting the distal end [4] of the unit upward such that the payload supported by the substructure [27] is horizontally positioned and balanced on the rescuer's shoulder (or such part of the body on which to balance the laden unit), and is now ready to be transported across water, foresty, rugged or such other terrain which is not conducive for the unit to be rolled on its wheel.
(f) A rescuer may carry the payload [35] on the said unit either on his shoulder or head or back or in his arms (or such part of the body on which to balance the laden unit) as convenient and may carry more than one units at a time for transportation on foot.
(g) In case the water body being traversed is too deep to wade/ford, the unit optionally fitted with the Buoying means can be made to float on the surface of the water whereby the rescuer can drag the said laden unit along, while swimming across the water.
METHOD OF UNLOADING PAYLOAD USING UNLOADING GEAR
(OPTIONALLY) PROVIDED IN EMBODIMENT 3 :
Where the Substructure [27] in a unit, is optionally provided with 'Unloading gear' [34], being Broad Strap(s) with tapering ends [34], such that a small area of about 1 to 2 square inches of the ventral side of each said broad strap/s is velcroed to a said member/Slat;
When the payload (especially injured human) contained in the said unit described in embodiment 3, is to be unloaded with minimal effort and stress to the rescuer and the rescued, the said tapering ends of each unloading gear [34] are fastened together, encircling the payload' s girth, by fastening means such as but not limited to buckles or tucktite fasteners (not shown in the drawings), and gently lifted out of the unit. Since the velcroed area is small (about 1 - 2 sq. Inches), the said unloading gear easily comes off the substructure [27]. In case of human payloads, without limitation, two to three numbers of the said unloading gear [34] may be provided per unit.
In case of a human payload, handled by a single rescuer, preferably first the lower end (the legs) of the payload is lifted slightly upward and moved out of the unit and finally the head along with shoulder/chest of the payload is transferred out.
