A field stretcher carrier with a structure formed by a front frame section and a rear frame section that are coupled together. The attachment systems that allow a stretcher to be secured to the structure favorably include at least one pair of clamps at the ends of each frame section. The clamps are fitted to a rigid cross bar and can slide up and down the axis of the cross bar toward and away from each other.

1. A field stretcher carrier comprising a structure formed by a front frame section and a rear frame section that are coupled together, the front and rear sections having at least one pair of legs connected by a pin to its respective section of the frame; the at least one pair of legs rotatable from an upright support position perpendicular to the underlying ground, to a mobile operational mode, wherein the legs are angled to the ground, and to a closed storage mode with the legs again perpendicular to the ground; a spring joined to each leg, positioned on each pin and suspended between the at least one pair of legs, aids in folding the legs; each pair of legs linked to a lower part of the frame by a central arm. 2. A field stretcher carrier as defined in claim 1, each central arm comprising two articulated levers, is pivotally joined to a central connecting cross bar with an opposite end of each central arm hinged at a fulcrum to an axle of a pair of legs, the central arm having a control pedal on both center arm ends, such that a foot pressure on the control pedal facilitates folding the articulated levers which allows folding the center arm at a shared end of the levers. 3. A field stretcher carrier as defined in claim 2, further comprising at least one pair of wheels and a pair of housings for the wheels, one pair of housings having a symmetrical axis with a center of the frame and the other pair of housings having an axis which is off-center of the frame. 4. A field stretcher carrier according to claim 3, wherein the separately spaced housings can position the wheels along at least two distinct parallel axes. 5. A field stretcher carrier as defined in claim 4, further comprising a bushing inside each housing that receives a pin for each wheel, wherein the bushings and corresponding pins provide a quick release system for quick and simple mounting and release of the wheels. 6. A field stretcher carrier as defined in claim 5, wherein the stretcher carrier includes a heterogeneity in relation to dimensions and degree of rigidity of stretchers, the carrier having movable attachment means. 7. A field stretcher carrier as defined in claim 6, the movable attachment means comprising clamps that slide along a rigid cross bar, and clamps urged by a maneuvering wheel on a threaded pin that allow continual, gradual adjustment to secure a stretcher. 8. A field stretcher carrier as defined in claim 7, wherein a diameter of the maneuvering wheel is 100 mm, (3.94″), or more, whereby opening and closing the stretcher securing clamps is quick and easy. 9. A field stretcher carrier as defined in claim 8, wherein at least one of the clamps includes push locking means for clamp securement in a number of separate positions designated by a series of holes in the cross bars. 10. A field stretcher carrier according to claim 9, wherein a pair of handles connects to each pair of legs and the handles are mobile and lockable in two or more positions. 11. A field stretcher carrier according to claim 10, wherein the wheels have rims that are made of composite materials and have a number of spokes. 12. A field stretcher carrier according to claim 11, wherein the structure is made at least in part of iron bars and/or tubes. 13. A field stretcher carrier as defined in claim 12, wherein the movable attachment means is adjustable for carrying stretchers having widths varying from 45 cm, (17.72″), to 65 cm, (25.6″). 14. A field stretcher carrier as defined in claim 13, wherein the structure while in storage mode has an overall space occupied that is reduced to 62 cm×52 cm×85 cm, or (24.409″)×(20.472″)×(33.4645″). 15. A field stretcher carrier as defined in claim 14, further comprising two pair of wheels. 16. A field stretcher carrier as defined in claim 15, wherein the wheels are concentric. 17. A field stretcher carrier as defined in claim 14, wherein the structure while in storage mode the wheels are fitted within a cavity formed by the folded carrier in a stabilized position within the structure. 18. A field stretcher carrier as defined in claim 17, wherein there is mutual contact between the clamps joined to each of the frame sections while the structure is in storage mode. 19. A method for using a field stretcher carrier as defined in claim 18, comprising the steps of: a. repositioning the field stretcher carrier from an upright support mode through an operational mode, and to a storage mode;b. folding the pairs of legs by pressing the control pedal in the center of them;c. rotation of a bottom portion of both pairs of legs toward a carrier center for an operational mode configuration of the carrier;d. removing the wheels with quick release of the pins;e. moving the handles to a suitable position for storage;f. fitting the wheels in special housings of the carrier, within a cavity formed by the folded carrier; andg. rotating the front and rear frame sections around a central fixing point to close up the wheels in the carrier until the pairs of leg are once again perpendicular to the ground and there is mutual contact between the clamps joined to each of the frame sections.
