A convertible cart device facilitates transport of a temporary structure and other items needed for use at a stock show, convention or the like. The device includes a pair of wheels coupled to a frame proximate a bottom end of the frame. A handle is removably couplable to a top end of the frame. A noseplate is removably couplable to the frame to define a hand truck. Each of a pair of side panels is removably couplable to the frame with first ends of the side panels being aligned with the top end and second ends of the side panels being outwardly spaced from the bottom end of the frame. The handle is removably couplable to the second ends of the side panels to define a hand cart.

This device relates to devices that can be used to transport equipment, tools and goods and other items from one location to another. The device can haul equipment such as test or analysis equipment. The device has a pocket and compartment for holding a laptop securely during transport. Affixed to the pocket is a folding first shelf for taking notes or working surface. There is a folding second shelf having telescoping holders for securing equipment. The device has wheels that roll smoothly over uneven surfaces. There are collapsing legs that are used to keep the device stable on uneven surfaces. A collapsing base is used to haul equipment, boxes and other large bulky or heavy items. The device is adjustable in the vertical direction to allow the user to adjust the shelf surfaces to a height that is comfortable.

A method of operating a payload-carrying vehicle having two laterally disposed wheels positioned along a central axis is described. The method includes measuring a force applied by a user to the hand truck, where the measured force comprising a direction and a magnitude, and providing torque to each wheel to cause each wheel to rotate in a respective direction as a function of the measured magnitude and direction. The amount of torque provided to each wheel in response to the force from the user is such that the magnitude of measured force applied by the user is not greater than a predetermined threshold value.

A store, move, and/or use apparatus for storing, moving, and using items implements an extendable support mechanism so that various work surfaces can be manually positioned at various elevations relative to the ground. The extendable support mechanism utilizes a plurality of support legs configured as a scissor lift. A storage container may be mounted on top of the extendable support mechanism. Additionally, wheel assemblies may be implemented to enable a user to move the apparatus.

A releasable wheel assembly is presented. The releasable wheel assembly includes a base plate and a bracket coupled to the base plate. The bracket includes multiple bosses and each boss includes a hole. An axle passing through the hole of each boss. The axle includes a circumferential groove adjacent to each end of the axle. Additionally, a brace is coupled to the base plate and the axle.

A modular cart assembly includes a first carrier unit that may contain an animal. A pair of wheels is provided. Each of the wheels is rotatably coupled to the first carrier unit. Thus, the first carrier unit may roll along a support surface. A first handle is coupled to the first carrier unit and the first handle may be manipulated. A pair of second carrier units is provided. Each of the second carrier units may contain an animal. Each of the second carriers units is selectively stacked on the first carrier unit. Thus, each of the second carriers units is transportable with the first carrier unit.

A wheelbarrow carrier provides transportation and dumping from a connection to a standard trailer hitch or tractor three-point mount. A pivoting ramp is used to load the wheelbarrow and a locking mechanism locks the wheelbarrow foot in place and the ramp in an upward position, once the wheelbarrow has been rolled onto the ramp and the ramp has pivoted from a downward position to an upward level position. The ramp pivots once the wheel of the wheelbarrow has rolled past the pivot point sufficiently to tip the ramp. Once the wheelbarrow is locked in the upward (level) position, a motor is activated to rotate a boom to which the ramp is attached with respect to a frame that is connected to the vehicle mount.

A pair of dollies for storing and transporting scaffold frames is disclosed. Each dolly is made up of two identical dolly members containing a top plate, bottom plate, two side pates and a front and back plate. Communicating holes are inserted along the length of the top and bottom plates. The side plates of each dolly member has semi-circular cut outs on the top edges which correspond with the holes in the top and bottom plates. The end holes at the front and back of each dolly member have tubes permanently inserted to receive a typical scaffold 8 inch swivel caster wheel with brake. Scaffold frame legs are inserted into the remaining holes in the top and bottom plates of the dollies. The bottom cross member of each scaffold frame sits on the semi-circular cut outs on the top edges of the side plates. This device can be used for storage or transportation of scaffold frames.

A wheeled hand-cart configured to carry and secure ski equipment and accessories is described. The hand-cart is of the type where a user adjusts an attitude of the hand-cart for rolling travel so as to balance the load about a wheel axis of the hand-cart. The hand-cart includes a load platform extensive enough to carry ski boots as well as a large securable container. Ski mounts joined to the hand-cart carry skis outboard of the load platform at an attitude that provides for ample clearance between the tips of the skis and the user's upper body. The ski-carrying cart may include a voluminous securable container to serve as a mobile ski locker, and locking devices may be provided to secure the skis and the cart. The hand-cart is further configured to partially collapse to a narrow-stance mode adapted for rolling travel in narrow spaces.

A combined device is adjusted between a scooter position and a handcart position. The combined device includes a front part provided with a steering assembly and at least one front wheel, and a rear part provided with at least one rear wheel. The front part is rotatably connected to the rear part in one pivot joint, or in a plurality of pivot joints having a common axis of rotation, such that on adjustment from scooter position to handcart position, the at least one rear wheel and the at least one front wheel are pivoted towards and against each other.
