DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT
(7) Referring now to the drawings and in particular to Drawing FIG. 1, a durable flexible sheet component 2 is preferably substantially square, such component having four substantially orthogonal edges forming 90 corners. In a preferred embodiment, the lengths of the sides of the durable flexible sheet component 2 are between five feet and eight feet. The sheet 2 is to thick, and preferably is composed of nylon fiber reinforced vulcanized rubber. Suitably, the durable flexible sheet 2 may be alternatively composed of other durable sheet materials such as heavy duty woven canvas.
(8) Referring to FIG. 1, the instant inventive assembly preferably further incorporates longitudinal and oppositely longitudinal pairs of D loops 4,18 and 26,22. Referring further simultaneously to FIGS. 1, 3, and 5, each D loop preferably comprises upper and lower bracket plates 6 and 14. In the preferred embodiment, the upper bracket plates 6 forming central hinge channels 8 for capture of and pivoting receipts of base ends of D loops, loop 4, 16, 18, 20, 22, 24, 26, and 28. Bolt fasteners 10 and 12 extend through eyes (not shown within views) within the durable flexible sheet 2, such fasteners engaging underlying bracket plates 14 and securely fastening the D loops at the periphery of the durable flexible sheet 2.
(9) Referring simultaneously to FIGS. 1 and 2, the instant invention further comprises longitudinal and oppositely longitudinal stays 30 and 32. Such stays 30 and 32 preferably comprise heavy duty steel bars having lengths slightly greater than the edge length of the durable flexible sheet 2. In a preferred mode of assembly, the steel bar stays 30 and 32 are respectively laterally extended through the longitudinal D loop pair 18 and 14, and through the oppositely longitudinal D loop pair 22 and 26.
(10) Referring simultaneously to FIGS. 2 and 4, lateral and oppositely lateral pairs of durable flexible loops 34 and 42, and 40 and 46 are preferably provided, such loop pairs engaging the longitudinal and oppositely longitudinal steel bar stays 30 and 32 for lateral slidable movements and positioning therealong. In the preferred embodiment, the durable flexible loops 34 and 42, and 40 and 46 comprise high tensile strength steel chains which incorporate releasable links 36, 44, 40, and 48.
(11) Upon overlying and longitudinal movements of lateral and oppositely lateral forklift tines 50 and 52 (such tines being deployed and operated via, for example, a skid steer loader having an auxiliary forklift attachment), the lateral and oppositely lateral pairs of durable flexible loops 34,44 and 38,46 may be respectively extended in encircling engagements with such tines 50 and 52 in the manner depicted.
(12) Referring simultaneously to FIGS. 4 and 5, a downed large livestock animal such as a steer 60 (represented in dashed lines or ghost) may be preliminarily rolled over the ground 62 and onto the upper surface of the durable flexible sheet 2. The pivot capabilities of the D loops 4, 16, 18, 20, 22, 24, and 28 advantageously allow movements between retracted positions (as represented by loop 28 in FIG. 5) which co-extend with the sheet 2 and upwardly extending or substantially 90 bar receiving positions (as depicted in FIG. 4). Such pivoting capabilities of the D loops advantageously allow a downed livestock animal 60 to be rolled directly over the D loops without any severe impingements of the loops against the animal's torso.
(13) Referring further simultaneously to FIGS. 4 and 5, operation of the forklift (not depicted within views) to raise the lateral and oppositely lateral forklift tines 50 and 52 may advantageously simultaneously raise the durable flexible loops 36,44 and 40,46, the stay bars 30 and 32, the longitudinal and oppositely longitudinal D loop pairs 4,18 and 26,22, the durable flexible sheet 2, and the downed livestock animal 60 over the ground 62 as indicated in Drawing FIG. 5. Thereafter, the operator of such forklift equipment may easily and conveniently drive the assembly, including the carried animal 60, to an appropriate place of care and processing.
(14) Referring simultaneously to FIGS. 1-3 and 6, it may be seen that each D loop among the longitudinal and oppositely longitudinal D loop pairs 4,18 and 26,22 is oriented and positioned at an angle a with respect to one of the sheet's corners. Such angled positioning of the D loops 4, 18, 22, and 26 advantageously causes their loop openings 5 to simultaneously face both corner edges for alternative bi-directional receipts of the stay bars. To facilitate such bi-directional stay bar receipts, each angle a is preferably approximately 45. Such corner D loop orientations allow the D loops to functionally serve as lateral and oppositely lateral D loop pairs 4,26 and 18,22. Such alternate lateral and oppositely lateral D loop pairs 4,26 and 18,22 may advantageously alternatively longitudinally receive the steel bar stays 30 and 32 in the manner depicted in FIG. 6. The instant invention's alternative provisions of longitudinal and oppositely longitudinal and lateral and oppositely lateral pairs of D loops advantageously allows forklift tines 50 and 52 to be extended either longitudinally or laterally for with respect to the sheet 2 loop engagements and sling carriage of a downed livestock animal.
(15) Referring simultaneously to FIGS. 1, 2, and 6, a plurality of intermediate D loops 16, 20, 24, and 28 are preferably provided, such intermediate D loops engaging midpoints of stay bars 30 and 32 in the alternate manners indicated in FIG. 2 and FIG. 6. The engagements of the intermediate D loops 16, 20, 24, and 28 with the stay bars 30 and 32 advantageously provide for consistent livestock carrying suspension and support along the edges of the durable flexible sheet 2.
(16) While the principles of the invention have been made clear in the above illustrative embodiment, those skilled in the art may make modifications in the structure, arrangement, portions and components of the invention without departing from those principles. Accordingly, it is intended that the description and drawings be interpreted as illustrative and not in the limiting sense, and that the invention be given a scope at least commensurate with the appended claims.
