ABSTRACT:
The “One-Hand Operation Conversion for Wheelbarrow Handles” added to a wheelbarrow, on one hand, offers single hand operability and maneuverability, and on the other hand offers added benefits to dual-handed users. The wheelbarrow can easily be converted from dual to single-handed operation and then back again with this said unit. This is completed by adding a centrally mounted handle to cross support(s) which are attached to the two longitudinally extending handles of the said wheelbarrow. When the center handle is attached, one-hand operation is achieved by the load balancing capabilities of the said handle and its mounting orientation. The center handle is formed into or mounted to the cross support(s) that are mounted to the existing longitudinal handles. The unit size dimensions and mounting method are arbitrary and will be made to fit the circumstances of mounting position and cross support material. The cross support(s) material and the handle material are of variable rigid form. The cross support mounts are variably rigid and can be adapted to fit the form of the said cross support(s) as well as conformed to the shape of the said wheelbarrows longitudinal handles. The cross support(s) offer the user a ergonomically padded contact area. This contact area can be used to apply a force by means of the lower body when the wheelbarrow is in use under heavy load.
