A handle assembly for a cart with a power assist function can sense the direction that a user's force is applied, and provide assist power in the corresponding direction, such that the user can easily move the cart. A cart including the handle assembly allows the user to conveniently move the cart.

A handle configured to be mounted on a pole (e.g., of an IV stand). The handle includes a handle grip having first and second ends with a central section therebetween. The central section is lower than the first and second ends. The handle grip is configured to be gripped by a user at a location between the central section and one of the first and second ends. The handle grip may include first and second sections that each extend upwardly from a central section. The first section is configured to be gripped at a natural grip angle by the user's a right hand and the second section is configured to be gripped at the natural grip angle by the user's a left hand. The handle may include a connector portion configured to be mounted to the pole and connected to the handle grip.

A wheelbarrow having an adjustable handle. The wheelbarrow has a bucket portion having a pair of sides and an axle accepting portion therein. An axle member is provided for insertion through the axle engagement member. The axle member has a pair of outer peripheral ends spaced on either side of the pair of sides. A pair of handles are pivotally attached to each of the pair of outer peripheral ends for allowing the handle to pivot away from the bucket portion of the wheelbarrow. Each side of the wheelbarrow has surfaces defining a plurality of handle engaging areas such that the handle may selectively be engaged in an area at a first position and selectively disengaged to move the handle to a second position. Each handle has a handle end portion which includes grip portions corresponding to the number of positions for the handles wherein each grip portion is configured at an angle for being substantially parallel to the ground when in a corresponding position in a selected corresponding slot in the wheelbarrow.

A hand propelled three wheeled cart for transporting miscellaneous cargo. The basic cart has a single front wheel with two solid rear supports, such as a standard wheelbarrow. The two rear wheels are attached to a lever that is pivotally connected to the lever mounting support brackets. Lifting the handles pries the two rear wheels, into position, elevating the rear cart support legs off the ground. This cam action reduces the operators lifting effort and improves the lateral stability of the cart. Releasing the handles automatically anchors the cart.

The pivoting-safety wheelbarrow handle is an apparatus that correctly positions and orients the grip of the user while operating a wheelbarrow. The apparatus may be integrated into the handlebar of a wheelbarrow or serve as a universal attachment with a variety of wheelbarrows. The apparatus includes an arched brace, an annular frame, a main handlebar, a first stopper, and a second stopper. The annual brace mounts and positions the annular frame. The annular frame fixes the main handlebar and orients the grip of the user. The main handlebar allows the user to grasp onto the apparatus and maneuver the wheelbarrow. The first stopper and the second stopper limit the rotation of the annular frame. The apparatus preferably includes a wheelbarrow handlebar that is integrates the apparatus to a wheelbarrow. Alternatively, the apparatus includes a handlebar-receiving sleeve that mounts the apparatus onto a handlebar of a variety of wheelbarrows.

A magnetic frame mechanism including an outer frame, first drop center wheels, first brackets, a permanent magnet block. The outer frame includes a face plate, a first side plate, and a second side plate. The first side plate and the second side plate are vertically fixed on two ends of the face plate, respectively. The permanent magnet block is sandwiched between the first side plate and the second side plate. The first side plate and the second side plate include guide structures, and the guide structures include first guide rails. The first drop center wheels are fixed on the inner side of the face plate via the first brackets, respectively. The platform mechanism includes a platform plate, four magnetic travelling wheels, four second brackets, a second guide rail disposed on the surface of the platform plate, and a tension spring.
