Multi-mode hand truck

摘要

A hand truck is convertible to assume an expanded use mode and a flat storage mode. The hand truck includes a rolling base and a base pusher. The rolling base is arranged to support goods and to roll on ground underlying the hand truck. The base pusher is mounted on the rolling base for pivotable movement about a base-pusher pivot axis from an upright hand-truck position to a storage position to rearrange the hand truck between the expanded use mode and the flat storage mode.

1. A collapsible hand truck comprising
a rolling base including a load-support frame and a toe-plate shelf coupled to the load-support frame, a base pusher mounted for movement relative to the load-support frame of the rolling base about a base-pusher pivot axis from an upright hand-truck position arranged to lie in generally coplanar relation to a top of the load-support frame of the rolling base to establish an expanded use mode to a storage position arranged to lie along the load-support frame of the rolling base to establish a flat storage mode of the hand truck, and hand-truck mode changer means for freeing the base pusher for rotation about the base-pusher pivot axis from the upright hand-truck position to the storage position in response to a user lifting a base-pusher rotation blocker with one hand and for allowing the base pusher to return to the upright hand-truck position from the storage position without further interaction with the base-pusher rotation blocker by the user so that the base pusher is freely movable to the upright hand-truck position from the storage position, wherein hand-truck mode changer means includes a pusher latch coupled to the base pusher for rotation with the base pusher about the base-pusher pivot axis as the base pusher is moved between the storage position and the upright hand-truck position and the base-pusher rotation blocker is coupled to the rolling base to pivot relative to the rolling base from a closed position arranged to block movement of the pusher latch relative to the rolling base to an opened position arranged to allow the pusher latch to move relative to the rolling base.
