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.

  • 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.
  • 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.
  • 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.
  • 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/
  • 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.
  • 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.
  • 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
  • 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].
  • 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.
  • 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.
  • 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;
  • each unloading gear [34] 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.
  • 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.
