A trigger is adjacent the handle configured to release the first frame portion from the second frame portion when the trigger is actuated such that the tub is readily dumped.
Claims16
A wheelbarrow comprising:
- a tub;
- a first frame portion coupled to, and providing support for, the tub;
- a wheel supported below the first frame portion;
- a second frame portion releasably coupled to the first frame portion and configured with a handle for gripping by a user;
- a first trigger adjacent the handle configured to release the first frame portion from the second frame portion when the trigger is actuated such that the tub is readily dumped;
- a wheel fork coupled between the wheel and the first frame portion, wherein the tub has a center of gravity and the wheel fork is coupled to the first frame portion between the handle and the center of gravity of the tub;
- and
- connecting rods coupled between the handle and the wheel fork, thereby providing support between the handle and the wheel fork when the wheelbarrow is in the released position.

A wheelbarrow comprising:
- a tub supported on a tub base and configured to carry a load;
- a handle configured to be gripped in the hands of a user, the handle pivotally connected to the tub base;
- a wheel fork coupled to the tub base on one end and to a wheel on another, the wheelbarrow configured to roll on the wheel;
- support legs coupled under the tub base and configured to support the wheelbarrow;
- and
- a lock coupled between the handle and the tub base and configured to lock the handle and the tub base together in a locked position and configured to allow the handle and the tub base to rotate relative to each other in a released position;
- and
- connecting rods coupled between the handle and the support legs, thereby providing support between the handle and the support legs when the wheelbarrow is in the released position;
- wherein releasing the lock changes the wheelbarrow from the locked position to the released position thereby causing the tub to tip forward when the user pushes forward on the handle.

A method of using a wheelbarrow comprising:
- carrying a load in a tub that is supported on a tub base;
- gripping a handle of the wheelbarrow, the handle pivotally connected to the tub base;
- moving the wheelbarrow while in a locked position by applying a force to the handle such that the wheelbarrow rolls on a wheel coupled the a wheel fork, the wheel fork coupled to the tub base;
- unlocking the wheelbarrow into a released position such that the handle and the tub base to rotate relative to each other and applying a forward force on the handle such that the tub tips forward dumping the load;
- and
- controlling the tub while the wheelbarrow is unlocked by connecting rods that are coupled between the handle and the wheel fork.
