  • Patent number: 8814180
    Abstract: It is connected to a lawn tractor or vehicle for towing any foldable sheet type material such as a tarp, (construction) plastic, or cloth across the ground to move large debris or material. This assembly contains multiple tubing, stabilizers, and hardware that allow a direct connection to a lawn tractor or a vehicle/ATV using a standard receiver type hitch. The sheet material is folded and then rolled onto the tarp connection tube and then attached to the tarp support tube. When towing, the clamping point gets tighter the harder you pull on it, making it a strong connection. Now the material is tightly gripped between these two tubes, which allow the use of any type of foldable sheet material for towing. This design eliminates the need to use any type of grommet load connection points within the sheet material that could be easily pulled out during heavy loads or use.

    Abstract: A lightweight, strong, sturdy, and versatile evacuation sled is disclosed. The body of the sled may be manufactured from a single piece of material, stored flat, and folded into its functioning configuration. When folded, the sled has one or more straps that help hold it in its folded configuration and allow maneuvering or carrying the sled. The sled may be readily towed with a towing harness and may be moved down an incline, such as stairs, by means of a rope and belay device. The sled has a low coefficient of friction and is lightweight, allowing the sled to be readily moved and handled without requiring the assistance of multiple people. Additional sleds with foam inserts may be provided to carry equipment such as for life support. The sled may also provide surge capacity for facilities like hospitals, as the sled is designed to be inexpensive and essentially disposable.

  • Patent number: 4262919
    Abstract: An articulated, body-steerable sled, particularly useful as a child's recreational sled, provides the user with a high level of protection against pinching and collision. In a preferred embodiment, the sled comprises two or more sled body units flexibly coupled together by a hinge. A cover plate locks over the hinge to hold it in position and covers the region between the two units to protect the user from pinching. Contoured portions in the sled body units permit the user to steer the sled with his body and, at the same time, protect his body against collision.

  • Patent number: 4114941
    Abstract: A crate grappling device having a generally U-shaped frame including a pair of coplanar arms and a cross member connected to the arms at one end. A pair of hook-like members are secured to the free ends of the arms, which are adapted to engage the wooden frame structure of a palletized crate so that with the aid of a winch or some other pulling device the crate may be dragged along the bed of a truck or trailer to the tailgate. Formed as an integral part of the hook-like members are skids which bear the wear of the grappling device as it is dragged along the bed.

  • Patent number: 4070030
    Abstract: A device which can be used as a sled towed by a vehicle such as a snowmobile which can be converted to a ramp for loading a snowmobile or any vehicle onto a transporting device such as a truck. The device is comprised of a frame having vertical sides forming a container with a pair of skids attached beneath the frame and a tongue or hitch attached to one end for towing purposes. The sides and ends are attached in a manner which permits them to be adjusted to a position for converting the body of the slid to a loading ramp. A transition piece is attached to the end of the frame for attaching the device to a transporter for loading purposes. The vertical sides are hinged to adjust to various positions and act as guides, if desired. The frame is provided with suitable attachment devices so that the hitch or transition piece may be attached to either end.

  • Patent number: 4046393
    Abstract: 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.

  • Patent number: 3937482
    Abstract: A self-uprighting tow sled designed to upright itself after spills. This sled generally comprises a unitary pre-formed hull having certain geometric configuration characteristics. This sled is pulled by a tow means positioned in the front thereof and below the center of gravity of the sled. As a result of the cooperative relationship between the sled, its particular geometric configuration, and the towing forces being below the center of gravity, the sled can be overturned during pulling and it will automatically upright itself.
