Abstract
A pallet sled includes an upper frame including spaced-apart arms adapted to receive feet of a pallet therebetween. A lower frame supports the upper frame. A plurality of pivotable arms connect the lower frame to the upper frame. A handle is pivotably connected to the lower frame and the upper frame, such that pivoting the handle selectively raises and lowers the upper frame relative to the lower frame.
Claims22
A pallet sled comprising:
- an upper frame having an upper surface;
- a lower frame supporting the upper frame;
- a plurality of pivotable arms connecting the lower frame to the upper frame;
- a handle pivotably connected to the lower frame and the upper frame, such that pivoting the handle selectively raises and lowers the upper frame relative to the lower frame;
- at least one ratchet plate pivotably coupled to the lower frame, to the handle, and to the upper frame;
- and
- an indexing bar movable between an engaged position in which the indexing bar prevents relative rotation of the handle relative to the at least one ratchet plate and a disengaged position in which the handle can pivot relative to the at least one ratchet plate, such that the handle can raise and lower the upper frame by pivoting relative to the lower frame when the indexing bar is in the engaged position and such that the handle can pivot relative to the lower frame without raising or lowering the upper frame when the indexing bar is in the disengaged position.

A pallet sled comprising:
- an upper frame having an upper surface;
- a lower frame supporting the upper frame;
- a pair of ratchet plates coupling the lower frame to the upper frame, the ratchet plates pivotable relative to the lower frame, wherein the ratchet plates are pivotable between a first position and a second position, wherein the upper frame is closer to the lower frame in the second position than in the first position;
- and
- a handle pivotably connected to the lower frame, wherein the handle is selectively engagable and disengageable with the ratchet plates, such that the handle can raise and lower the upper frame by pivoting relative to the lower frame when the handle is engaged and such that the handle can pivot relative to the lower frame without raising or lowering the upper frame when the handle is disengaged.

A pallet sled comprising:
- an upper frame;
- a lower frame supporting the upper frame;
- a plurality of wheels supporting the lower frame;
- a ratchet plate pivotably connected to the lower frame about an axis, the ratchet plate pivotably coupled to the upper frame, wherein the ratchet plate is pivotable between a first position and a second position, wherein the upper frame is closer to the lower frame in the second position than in the first position;
- and
- a handle pivotably connected to the lower frame about the axis, wherein the handle is selectively engagable and disengageable with the ratchet plate, such that the handle can raise and lower the upper frame by pivoting relative to the lower frame when the handle is engaged and such that the handle can pivot relative to the lower frame without raising or lowering the upper frame when the handle is disengaged.
