US Patent 11034371 Pallet sled

A pallet sled includes a lower frame and an upper frame. A plurality of pivot arms pivotably connect the upper frame to the lower frame. The upper frame is movable between a lowered position and raised position. The upper frame is spaced further from the lower frame in the raised position than in the lowered position. The upper frame is rotated slightly relative to the lower frame when moved from the lowered position to the raised position. In the example embodiment, the upper frame is rotated approximately 1.5 degrees to approximately 2.0 degrees toward the upright handle of the pallet sled.
