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 wheel barrow 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.

Claims (21)

1. A convertible wheeled device for carrying a load comprising an elongate frame with a pair of handles extending from one end of said frame and a pair of wheels pivotally secured either side of said frame at an end thereof opposite said handles, said wheels being movable between a first operating position where said wheeled device is self supporting in a vertical orientation of said frame and a second position where said frame is at an angle to a support surface and said wheels have moved rearwardly away from said end of said frame opposite said handles.
2. A convertible wheeled device as claimed in claim l wherein said device is a hand truck with a support plate extending from said frame at said end opposite said handles.
3. A convertible wheeled device as claimed in claim 2 including a load carrying cavity member interior to said frame and behind said frame.
4. A convertible wheeled device as claimed in claim 2 including a control linkage for moving of said wheels between said first and second positions.
5. A convertible,wheeled device as claimed in claim 3 including a control linkage for moving of said wheels between said first and second positions and wherein said control linkage forms a support leg arrangement rearwardly of said wheels to form a wheelbarrow type device.
6. A convertible wheeled device as claimed in claim 5 wherein said linkage is an over center linkage having a bias maintaining said linkage in the first operating position unless moved by a user to cause the wheels to move towards the second position.
7. A convertible wheeled device as claimed in claim 4 wherein said linkage is an over center linkage having a bias maintaining said linkage in the first operating position unless moved bar a user to cause the wheels to move towards the second position.
8. A convertible wheeled device as claimed in claim wherein said wheels are movable to said second position after a load has been positioned on said support plate and in said second position the force of said load is primarily carried by said frame.
9. A convertible wheeled device as claimed in claim 8 wherein the force of said load provides a bias moving said wheels to said second position after said linkage has moved through the center position of said linkage.
10. A convertible wheeled device as claimed in claim 1 wherein said device in said second position can act as a modified hand truck for carrying of loads to a front side of said frame and can act as a wheelbarrow with a load being supported in a open top container located behind said frame with the open top of said container being accessible through said frame.
11. A convertible wheeled device as claimed in claim 1 including a pair of lifting arms movable to a position forwardly of said frame for suspending a load between said support arms as said handles are moved downwardly causing said arms to rise and suspend the load therebetween.
12. A convertible wheeled device as claimed in claim 11 wherein said lifting arms are interconnected and pivotally secured to said wheeled device adjacent said end of said frame opposite said handles.
13. A convertible wheeled device as claimed in claim 12 wherein said lifting arms include a bias arrangement urging said arms to a storage position generally parallel to said frame.
14. A convertible wheeled device as claimed in claim 13 wherein said lifting arms at free ends thereof including a support arrangement for allowing suspension of load generally centered between said free ends.
15. A convertible wheeled device as claimed in claim 14 said lifting arms are each slotted at the free end thereof to engage a chain.
16. A convertible wheeled device as claimed in claim 15 including a chain and belt lifting arrangement, said belt being adjustable for securing about a periphery of an object to be lifted, said belt including two chains for engagement with sand lifting arms.
17. A convertible wheeled device as claimed in claim 1 wherein said device is a wheelbarrow which storable in a vertical orientation with said frame upright with said wheels in said first position, said wheelbarrow in said second position of said wheels being in a generally horizontal orientation of said frame by means of foldable legs extending downwardly relative to said frame.
18. A convertible wheeled vehicle as claimed in claim 17 wherein said foldable legs are part of a control linkage connected to and controlling the position of said wheels.
19. A convertible wheeled vehicle as claimed in claim 18 wherein said control linkage engage a stop member attached to said frame.
20. A convertible wheeled vehicle as claimed in claim 1 wherein said vehicle is a hand truck operable in a conventional manner with said wheels in said first position and with said wheels in said second position said hand truck supports a load positioned adjacent said end of said frame opposite said handles in a counterbalanced manner.
21. A wheelbarrow comprising an elongate frame, a pair of coaxial wheels attached at one end of said frame 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 located generally within and behind said frame, and accessible through 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.
