A cart for restocking provisions includes a body having one or more exterior surfaces. The one or more exterior surfaces include a top surface facing a first direction and a bottom surfacing facing a second direction that is away from the first direction and parallel to the first direction. The cart also includes a handle fixedly attached to the body. The cart further includes one or more wheels coupled to the bottom surface. In addition, the cart includes one or more hoppers each including a hollow space having a length that extends from an aperture located on the top surface and through at least a portion of an interior of the body. The hollow space includes at least one curved surface that extends from the aperture along at least a portion of the length to allow the provisions to be stored within the one or more hoppers.

A motorized device for transporting a human or inanimate payload. A platform is configured to accommodate the payload and a pair of wheel clusters are mounted to the platform at opposite ends thereof and are powered in both rotation and in translation relative to the platform, for example by one or more electric motors housed in or on the platform or wheel clusters. Each of the wheel clusters comprises an arm, and a first and a second wheel rotatably mounted to respective opposite ends of the arm. Each of the wheels is independently powered about its respective axis of rotation. An electronic controller commands the motors to enable stable rolling movement of the device over a surface with only one wheel of each cluster in contact with the surface, and to allow the device to steer and to ascend and descend steps.

A transporting apparatus including a top portion pivotally coupled to a middle portion via a latching assembly, the latching assembly including a biasing element and a latching element, the biasing element biasing latching element in a closed position which releasably secures the top portion to the middle portion in an extended position.

Cart apparatuses and related methods are described that are configured to traverse uneven terrain while carrying heavy loads such as game animals or equipment. In one example, the cart has a frame that has a handle structure and at least one cargo support portion. At least one wheel support assembly is configured to pivot around an axle connected to the frame. A first wheel and a second wheel may also be included, with the first and second wheels each being pivotable relative to the at least one wheel support assembly. The first wheel may have a first axis of rotation offset from and parallel to the axle, and the second wheel may have a second axis of rotation offset from and parallel to the axle. These carts and methods may make travel through uneven terrain and wilderness areas faster and more conveniently for outdoorsmen.

Disclosed is a folding hand truck capable of moving over uneven or spongy surfaces and surmounting obstacles. The chassis includes a frame having a lower end and a reference plane, a platform attached rotatable around pivot axis to said lower end, two arms, each having a first axis and a second axis, each of said arms attached rotatable around the first axis to said lower end and configured for attaching a wheel arrangement rotatable around the second axis and having a diameter at least equal to a half of a width of said frame, and two intermediate elements, each of said intermediate elements configured for synchronizing motions of said platform and one of said arms providing for said platform and said arms linearly interdepended rotation.

A multi-wheel system that minimizes wheel interactions with discontinuous and uneven surfaces. The multi-wheel system comprises wheels of varying diameters connecting to a rotating arm configured to raise and lower the wheels in response to obstacles along the rolling surface.

Embodiments of the present disclosure may include a collapsible cart configured to transition from a closed condition where it may be folded up to an open condition where it may be expanded for use, the collapsible cart including a rigid frame forming a compartment, the rigid frame having a front wall, a rear wall, a right sidewall, a left sidewall, and a bottom wall, the right sidewall and the left sidewall may be configured to fold inwardly in the closed condition. In some embodiments, the right sidewall including a first right panel rotatably coupled to a second right panel. In some embodiments, a retractable handle mechanism is disposed at, within or adjacent the back wall. The retractable handle mechanism includes a hand grip attached to a telescoping assembly. The telescoping assembly is pivotably coupled at a proximal end to the bottom of the rear wall.

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 wheel-alternate stair climbing cart at least has one row of wheels (preferably two or more rows of wheels). Each row comprises a plurality of wheels. Two adjacent groups of wheels are intersected. The total length formed by connecting axle centers of a plurality of wheels can at least cross a vertex of three steps. The wheels on the stair at least keep contact with a vertex of two steps. The present invention better solves the problem that a traditional cart is blocked when operating on the stair or is bumpy when moving, and has the advantages of strong weight loading capability, difficult wear and low manufacturing cost.
