A portable plastic sled for the rescue of injured persons and disabled snowmobiles. The sled is constructed of heavy gauge low density polyethylene having a molecular memory and formed to lay substantially flat when unrolled with the exception of the front portion which retains a partial curvature. A transverse bar at the front of the sled includes a socket for attachment of a separate crank to enable the sled to be conveniently rolled into a tight bundle for stowage aboard a snowmobile or all terrain vehicle. The crank is formed with attachments to permit use as a handle for manual towing or as a towbar for snowmobile towing. The crank also becomes a convenient carrying handle when the sled is rolled up. An integral tail on the sled retains the sled in the rolled up condition and multipurpose clasp lines retain the crankhandle to the rolled up sled.
A portable sled comprising, an oblong flexible plastic sheet having a front end and a back end, a bar extending transversely along at least a portion of the front end of the sheet and fastened thereto, the bar including engagement means at one end thereof, a separate crankhandle, engagement means on the crankhandle adapted to engage the engagement means on the bar thereby permitting rotation of the crankhandle to tightly roll up the sled, and, separate attachment means on the sled and separate attachment means on the crankhandle to permit at least one alternative attachment of the crankhandle with the sled.
A portable sled comprising, an oblong flexible sheet, a separate crankhandle, at least two separate attachment means on the crankhandle and at least two separate attachment means on the sled to permit at least two optionally selectable attachments of the crankhandle to the sled.
