Abstract
A pallet sled includes a lower frame and a plurality of wheels supporting the lower frame. An upper frame is configured to support a pallet thereon. A ratchet is configured to lift the upper frame relative to the lower frame. A handle is configured to operate the ratchet to lift the upper frame relative to the lower frame. The handle may be pivotable relative to the lower frame. The ratchet may include a gear and a pawl. The ratchet may also be configured to selectively lower the upper frame. As another option, one or more of the handle, the upper frame or the plurality of wheels are reconfigurable between an extended position and a retracted position.
Claims24
A pallet sled comprising:
- a lower frame;
- a plurality of wheels supporting the lower frame;
- an upper frame for supporting a pallet thereon;
- a ratchet configured to lift the upper frame relative to the lower frame, wherein the ratchet includes a gear and a pawl;
- a handle configured to operate the ratchet to lift the upper frame relative to the lower frame;
- a catch bar movably coupled to the handle and selectively engaging the gear;
- and
- an outer plate pivotably mounted relative to the lower frame and configured to selectively disengage the catch bar from the gear.
A pallet sled comprising:
- a lower frame;
- a plurality of wheels supporting the lower frame;
- an upper frame for supporting a pallet thereon;
- a ratchet configured to lift the upper frame relative to the lower frame, wherein the ratchet includes a gear and a pawl;
- a handle configured to operate the ratchet to lift the upper frame relative to the lower frame;
- and
- a catch bar movably coupled to the handle and selectively engaging the gear, wherein the handle is pivotable down into a folded position generally parallel to the upper frame and wherein the catch bar selectively locks the handle in the folded position.
A pallet sled comprising:
- a base;
- a lower frame connected to the base;
- a plurality of wheels supporting the lower frame and the base;
- an upper frame pivotably secured to the lower frame, the upper frame configured to support a pallet thereon;
- a gear coupled to the upper frame, such that rotation of the gear in a first direction lifts the upper frame relative to the lower frame;
- a pawl engaging the gear to prevent rotation of the gear in a second direction opposite the first direction;
- a spring biasing the pawl against the gear;
- an outer plate configured to reposition the spring such that the spring would bias the pawl away from the gear;
- and
- a handle configured to rotate the gear in the first direction.
A pallet sled comprising:
- a lower frame;
- a plurality of wheels supporting the lower frame;
- an upper frame configured to support a pallet thereon, the upper frame movable toward and away from the lower frame;
- a handle secured at a forward end of the lower frame;
- and
- a wheel extension secured to the lower frame, at least one of the plurality of wheels secured to the wheel extension, wherein the wheel extension is reconfigurable between an extended position forward of the lower frame and a retracted position within an envelope of the lower frame.
A pallet sled comprising:
- a lower frame;
- a plurality of wheels supporting the lower frame;
- an upper frame for supporting a pallet thereon;
- a ratchet configured to lift the upper frame relative to the lower frame, wherein the ratchet includes a gear and a pawl;
- a handle configured to operate the ratchet to lift the upper frame relative to the lower frame;
- a catch bar movably coupled to the handle and selectively engaging the gear;
- and
- a spring biasing the pawl toward the gear when the ratchet is in a lifting mode, the spring biasing the pawl away from the gear when the ratchet is in a lowering mode.
A pallet sled comprising:
- a lower frame;
- a plurality of wheels supporting the lower frame;
- an upper frame for supporting a pallet thereon;
- a ratchet configured to lift the upper frame relative to the lower frame, wherein the ratchet includes a gear and a pawl, the gear including a plurality of teeth extending outward from an outer periphery thereof, the pawl configured to engage the plurality of teeth;
- a handle configured to engage the plurality of teeth to operate the ratchet to lift the upper frame relative to the lower frame;
- and
- a spring having a first end coupled to the pawl and an opposite end coupled to a slot, such that movement of the opposite end of the spring in the slot changes the spring from biasing the pawl against the gear to biasing the pawl away from the gear.
