A rotational sliding bearing having a static part and a mobile part, each having a sub-shell with a sliding surface, each surface arranged within an angular range of max. 180° relative to the rotational axis in the direction of rotation of the bearing, and in a closed rest position, the sub-shells of all parts together form a bearing bush, the mobile part is arranged to pivot about a pivot axis for opening the bearing relative to the static part, such that a shaft mounted in the bearing is released in a release position, and the mobile part is shaped such that, based on the sliding surface position relative to the rotational axis, in the closed rest position, a translation of a shaft accommodated in the bearing is prevented transversely to the rotational axis and in the direction of the pivot axis of the mobile part or in the counter direction.

A moving body includes a travel drive section, and a transporting section that is disposed above the travel drive section (a drive housing and a power housing). In the moving body, the transporting section has a substantially rectangular shape and is provided with a vertical bumper at any of corner portions in top view, the vertical bumper extending in a height direction.

This application describes carts having a single vertical frame supported by a tripod-like leg structure. They are collapsible, extendable, and able to accommodate a wide variety of different accessories. To add accessories, carts can include one or more coupling components. Each coupling component includes at least one clamp that can be tightened around a cart's vertical frame along with a female coupler and a male coupler. The female coupler can be attached to a clamp and a male coupler can be attached to an accessory. The male coupler features a v-shaped extrusion and the female coupler features a complementary v-shaped intrusion allowing the male coupler to couple with the female coupler so that accessories can be added to the cart in a cantilevered manner.

A collapsible, motorized cargo cart includes an electric motor and a foldable frame that folds down flat for storage and transport. The frame member includes upper and lower frame portions in pivoting relation, and they can be positioned and locked at any desired angle with respect to each other. The lower frame member includes an extension that may be extended or retracted, as desired. Handlebars are provided on the upper frame member, and a throttle controls the speed of the cart, which is capable of transporting at least 300 pounds over rough terrain. Two large wheels are positioned on either side of the cart, and a removable caster wheel may be attached to a front portion of the frame. An electric motor and rechargeable battery are disposed on an underside of the frame's lower portion, and include a drive assembly to power the side wheels.

The invention is directed to a golf trolley comprising a main frame for mounting a golf bag, a handle portion, which is pivotably attached to the main frame at a handle joint, a first main wheel attached to a first main wheel mount, wherein the first main wheel mount is pivotably attached to the main frame, pivotable about a swivel axis. For easy folding and unfolding of the golf trolley, the first main wheel mount is displaceable parallel to the swivel axis, wherein the handle portion is mechanically coupled to the first main wheel mount such that folding the handle portion at the handle joint drives the first main wheel mount to rotate about the swivel axis and to move linearly along the swivel axis.
