Abstract
A multi-function hand truck is convertible to allow lifting of a load at a spaced distance from the truck and/or is convertible for use as a wheelbarrow. A pair of lifting arms co-operate with the frame of the hand truck to extend outwardly therefrom and allow the frame of the hand truck to provide a mechanical advantage for lifting. The wheels of the truck are moveable rearwardly for conversion to a wheelbarrow mode. An open top container is positioned within the frame of the hand truck for receiving material. The multi-function hand truck is efficiently stored in a vertical orientation.
Claims16
A wheelbarrow comprising a pair of wheels having a common rotational axis adjacent one end thereof positioned on opposite side of an open top shallow formed container, said wheelbarrow at an end thereof opposite to said pair of wheels including two spaced rearwardly extending handles with the handles located on opposite sides of said wheelbarrow, said wheelbarrow including a pair of foldable legs movable from a storage position adjacent a lower surface of said container to a load support position extending downwardly and away from said container for supporting said wheel barrow with the open top of the formed container orientated generally horizontally;
- said pair of wheels being secured by a movable mounting arrangement controlling movement of said pair of wheels between a wheelbarrow operational position intermediate the length of said container with said rotational axis of the wheels below said formed container to a wheelbarrow storage position with said wheels and said rotational axis in front of said formed container and cooperating with a front support;
- said pair of wheels in said wheelbarrow storage position cooperating with said front support to define a said vertical storage position of said wheelbarrow with said legs in said storage position having a depth generally corresponding to the depth of said formed container.
A wheelbarrow comprising an elongate frame, a pair of coaxial wheels attached at one end of said frame either side thereof and movable between a vertical storage position and a wheelbarrow position, a pair of handles extending from said frame at an end thereof opposite said wheels, an open top container supported by said frame and located generally within and below said frame, foldable leg means attached to said wheelbarrow and movable between a storage position collapsed adjacent said elongate frame and an in use position extending outwardly away from said frame;
- said wheels in said vertical storage position cooperating with a support portion on an end of said frame to provide a vertical storage position of said wheelbarrow having a depth corresponding to the depth of said open top container;
- said pair wheels of wheels in said wheelbarrow position being located beneath said container and intermediate a length of said container.
A convertible wheelbarrow comprising an elongate frame with a handle arrangement extending from one end of said frame, a movable wheel arrangement pivotally secured to said frame at an end thereof opposite said handle arrangement, an open topped container secured within said frame and extending below said frame, and a leg support arrangement space rearwardly of said movable wheel arrangement, said leg support arrangement being movable between a storage position with the leg support arrangement being adjacent and extending generally in a length of said container and a load support position where said leg support arrangement extends at an angle away from said container;
- and wherein said wheel arrangement is movable between a first position immediately adjacent said end opposite said handle arrangement where said wheelbarrow is self supporting in a vertical orientation of said frame and said container to an in use second position where said frame is at an angle to a support surface and said wheel arrangement is spaced from said end opposite said handle arrangement and moved towards said handle arrangement and beneath said open topped container having a horizontal orientation;
- wherein said wheelbarrow is self supporting in a space efficient generally vertical orientation of said frame with said wheel arrangement in said first position positioned beneath a front edge of said container with said leg arrangement in said storage position and said wheelbarrow is convertible to a working configuration with said wheel arrangement in said in use position and said leg support arrangement in said load support position.
