While this invention is susceptible of embodiments in many different forms, there is shown in the drawings and will herein be described in detail preferred embodiments of the invention with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the broad aspect of the invention to the embodiments illustrated.
Referring to the figures, embodiments of a fire rescue device 10 comprise a foldable unit or mat 14. Each embodiment primarily includes a plurality of semi-rigid panels sewn into a flexible cloth or cloth-like material such as canvas, Nomex, Kevlar, or the like. The mat folds into a size small enough to fit in the pocket of standard firefighter pants called turnout pants. Each panel may be sewn into a separate compartment such that the mat folds along seams between adjacent panels. In certain embodiments, the mats have eight equally sized center panels arranged in two columns of four. Opposing wing columns each consist of two additional panels of equal size to the center panels and two smaller roughly half-sized panels at the top and bottom of the wing columns. Holes/handles may be included in the wing columns.
The mat 14 includes an outer skin 18 of a flexible material. Flexible as used herein is used to indicate a material that can be readily folded and unfolded many times without undergoing plastic or permanent deformation. The flexible material is preferably chosen from a group consisting of a high-density polyethylene, a meta aramid, a cotton, a wool, a fiberglass, and a para-aramid. The outer surface may have a dragging or an engagement surface 22 comprising a friction reducing material, such as a polymeric material, e.g. plastic, or a specialized coating, e.g. a Teflon coating or the like, to facilitate dragging of a victim secured to an opposite surface of the mat.
The outer skin 18 forms a plurality of pockets arranged in columns and rows. A pair of adjacent center columns 32, 36 comprises four rows of equally-sized rectangular pockets 42. These pockets 42 are preferably equally sized, but can be varied as deemed necessary to provide the necessary function of foldability.
Wing columns 38, 40 are located on opposing sides of the adjacent center columns 32, 36 such that the adjacent center columns 32, 36 are located between the wing columns 38, 40. Each wing column 38, 40 comprises a pair of rectangular pockets having a size substantially equal to the pockets 42 of the adjacent center column. Each wing has two smaller pockets 44 which take the shape of a right trapezoid. These smaller pockets 44 are located on opposing sides of the pair of rectangular pockets wherein the right trapezoidal pockets 44 are located at corners of the rescue mat 14. This arrangement forms an octagonal shape. The octagonal shape includes a pair of first parallel edges separated from a pair of parallel second edges by angled edges formed by the right trapezoidal pockets 44. A length of the outer skin 18 is greater than a width of the outer skin 18.
Support members are located within the pockets. The support members are at least semi-rigid and may be produced from a polymeric material or a carbon-fiber material in the form of thin plates. Preferably, the support members comprise twelve equal-sized plates 48 located within twelve rectangular pockets formed by the outer skin 18 and four equal-sized smaller plates 52 located within the right trapezoidal pockets 44 formed by the outer skin 18. The twelve-equal-sized plates 48 and the four equal-sized small plates 52 have a rectangular shape.
Again, the plates 48 are preferably equally-sized. However, the size requirement of the plates can be varied in order to accomplish or achieve the necessary function of foldability of the mat 14.
Linear fold lines 56 separate pockets from adjacent pockets. The fire rescue mat 14 can be folded along these fold lines 56 according to the direction of arrows indicated in the figures to reduce an overall size of the fire rescues mat 14. Each fold line 56 comprises a seam delimiting each pocket. The seams are formed by joining opposite surfaces of the outer skin 18 by an attachment. Examples of suitable attachments include sewing, welding, hook and loop, rings, and spiral binding. The mat 14 is preferably foldable such that it fits within a standard thigh pocket of a standard pair firefighter's trousers (see

The linear fold lines 56 define a plurality of zones arranged in columns and rows. Again, the fire rescue mat apparatus 10 can be folded along the fold lines 56 to reduce an overall size of the fire rescue mat apparatus 10. The zones are similar in area to the area of the pockets of the previous embodiment.
The size, placement, and location of the support members in this embodiment are similar in this embodiment, except for the fact that the support members are not secured within pockets. Rather, here, the support members have an exposed surface and an opposite surface attached to the upper surface of the outer skin 18.
One embodiment includes a retainer 72. The retainer 72 is attachable to the rescue mat 14 when in the fully folded condition and is configured to maintain the rescue apparatus in the fully folded condition. It may be attached via hook and loop, snaps, buckles, carabiners, or any suitable variation or substitute thereof.
In one embodiment, the fire rescue mat 14 qualifies as a Class 2 rescue harness. A Class 2 Chest harness is used when there are only limited fall hazards (no vertical free fall hazard), or for retrieving persons such as removal of persons from a tank or a bin. In this embodiment, leg or groin straps are included as depicted in the figures.
In one embodiment, air cylinders 100 under pressure can be activated to support or immobilize the victim's spine or cervical areas. Here, at least some of the pockets 104 have a fluid-tight seal and wherein these pockets 104 can be inflated. Air cylinder 100 could also be activated to promote circulation from extremities to the victim's torso. This can redirect blood flow from extremities to the torso. (See

The main body 1022 has a rectangular shape and a top surface 1030 and a bottom surface 1034. It comprises a pocket 1038, a flap 1040 which closes the pocket 1038, and an aperture 1042 through which the sling 1018 is accessible.
The pocket 1038 is formed by folding a first portion 1043 of the main body 1022 over a second portion 1044 of the main portion. These portions are maintained in position by fasteners. One type of fastener that is particularly useful is the hook and loop fastener. Hook and loop fasteners 1046 are generally the preferred fastener for connecting the various elements of the retainer 1014 and the sling 1018; however, one of ordinary skill would understand that other fasteners could be used as a simple substitution to perform the function of holding two elements together. A first hook and loop fastener 1046 sewn to an edge of the top surface 30 of the main body 1022 is brought into engagement with a second hook and loop fastener 46 sewn to the top surface 1030 of the main body 1022. By this folding, the pocket 1038 is created.
The flap 1040 is formed by further folding of a third portion 1050 of the main body 1022 over the pocket 1038 to close the pocket 1038. Another hook and loop fastener 1046 is sewn to the edge of the top surface 1030 and is brought into engagement with a hook and loop fastener 1046 on the bottom surface 1034 of the first portion of the main body 1022. This closes the pocket 1038 with the flap 1040 and retains the elements in desired position.
The aperture 1042 takes a slotted form. It is located between the second portion 1044 of the main body 1022 and the third portion 1050 of the main body 1022.
A tongue 1054 extends outwardly from a side of the rectangular main body 1022 and parallel to a length of the aperture 1042. The tongue 1054 has a substantially rectangular shape and is integral with and extends outwardly from the main body 1022. The tongue 1054 has a length about equal to a length of a first side of the main body 1022 which is substantially parallel to the tongue 1054. The tongue 1054 intersects a second side of the main body 1022 which is transverse to the first side and shares a portion of the second side. The tongue 1054 comprises a top surface 1058 and a bottom surface 1062.
The top surface 1058 of the tongue 1054 is conterminous with (i.e. shares a boundary with) the top surface 1030 of the main body 1022. The top surface 1058 has a nonslip surface which is configured to engage an outer skin of a tubular-shaped firehose 200 when the retainer 1014 is wrapped circumferentially about a firehose 200.
The bottom surface 1062 of the tongue 1054 is conterminous with the bottom surface 1034 of the main body 1022. The bottom surface has a hook and loop fastener 1046 sewn thereon. The hook and loop fastener 1046 is configured to fasten to a complimentary hook and loop fastener 1046 on the bottom side 1034 of the main body 1022.
The sling 1018 is extendable from the pocket 1038 in the retainer 1014 and preferably has U-shape. The sling 1018 has a pair of ends 1066 each sewn to the top surface 1030 of the main body 1022 within the pocket 1038.
An intermediate section of the sling 1018 comprises a pair of sets of accordion folds 1070 beginning at each of the pair of ends 1066 and moving outwardly towards a center portion 1074 of the sling 1018.
The center portion 1074 has a hook and loop fastener 1046 which is provided to attach to a hook and loop fastener 1046 on the top surface 1030 of the main body 1022 on the flap 1040 adjacent the aperture 1042. A folding of the third portion 1050 of the main body 1022 to produce the flap 1040 causes the center portion 1074 to reside within the aperture 1042 and to be visible on the bottom surface 1034 of the main body 1022 through the aperture 1042. The pair of sets of accordion folds 1070 is stored within the pocket 1038. A color-alert 1078 attached to the center portion 1074 is visible through the aperture 1042.
A pull tab 1082 is attached to the center portion 1054, preferably by sewing. The pull tab 1082 extends outwardly from the aperture 1042 in the main body 1022.
