A releasable wheel assembly includes a bracket having a plurality of bosses, each boss including a hole that receives an axle. A pair of wheels are mounted on the axle and a pair of locking caps fit over respective ends of the axle, the locking caps each including a clip for engaging the axle at a circumferential groove to prevent movement of the locking cap along the axle. The wheel assembly can be mounted to a carry bag or other storage unit by mounting the bracket to the storage unit, where the wheels and axle can be easily removed from the bracket.

An exercise device having a sled or wheelbarrow configuration comprises a frame that is pushed across a support surface by a user. The frame carries a wheel that movably supports the frame in the wheelbarrow configuration and at least one skid that movably supports the frame in the skid configuration. A pair of handles is selectively repositionable on the frame from a vertical orientation used in the sled configuration and a horizontal orientation used in the wheelbarrow configuration to quickly and easily convert the device between its different configurations. The frame has a carriage that supports a plurality of exercise weight members with the carriage being movable in a fore-and-aft direction on the frame for changing the effort required from the user to push the frame.

A handcart comprising a frame, a double handle grip, a load accommodating bottom shelf and a load accommodating top shelf, the top shelf being pivotably secured to the double grip handle, wherein the double grip handle of the handcart includes a U shaped top piece which is secured to the double grip handle by bolts that allow the U shaped piece to pivot or swing to a position parallel to the ground. The pivoting or swinging action of the U shaped top piece is accomplished by way of a spring mechanism fitted onto the double grip handle, thereby allowing the pivotably secured top shelf to accommodate heavy loads.

A mobile cart includes a cart frame, wheels rotatably attached to the frame and feet projecting from the frame to an underlying support surface. A carrier tray is fixedly secured atop the cart frame, having a generally planar tray base, a front wall extending upwardly from the front end of the tray base and a cavity. A first container, containing a first material, and a second container, containing a second material, are positioned in the cavity. A combination mixer and dispenser is releasably secured to the frame and releasably fluidly coupled to the first and second containers. The cart is tiltable between a generally horizontal position and a generally vertical position. The front wall of the tray is angled from the tray base such that the front wall lies against the support surface in the generally vertical position, stabilizing the cart for container loading and unloading.

A vehicle has first and second parts with at least one road wheel. The first part pivotally connects to a connecting member at two spaced apart points to pivot about a first axis relative and the second part pivotally connects to the connecting member at two spaced apart points 18 to pivot about a second axis, which is perpendicular to the second axis, intersecting at a pivot point. A first drive shaft rotatably mounts to the first part and extends in a direction perpendicular to a longitudinal axis of the first part, a second drive shaft rotatably mounts to the second part and extends in a direction perpendicular to a longitudinal axis of the second part. The first and second drive shafts connect by a universal joint so that the two shafts to pivot relative to each other about the pivot point.

The present invention comprises a wheelbarrow for use on a surface. The wheelbarrow is generally comprised of a first and second handle, a receptacle, a chassis, at least one leg, a front wheel, a back wheel and an assembly. The assembly includes a on which allows back wheel to pivot between a first position and a second position. When the back wheel is in the first position, the legs are in contact with the surface. When the back wheel is in the second position the legs are raised off of the surface.

Movable containers for transporting materials using the motive power of a person are described. The containers include a recess at a bottom end thereof that may extend substantially along a width of the container. An elongated roller is partially located within the recess. The roller may extend substantially along the entirety of the recess and may have a variety of tread patterns. The container may further include more than one roller. More than one roller may be partially located within the recess of the container.
