The present invention relates to a running gear having a carrier plate and a first roller, a second roller and a third roller, which are arranged on the carrier plate. Simplified handling and/or increased stability of the running gear is produced if the first roller can rotate about a first rolling axis running parallel to a plane of extent of the carrier plate and the second roller can rotate about a second rolling axis running parallel to the plane of extent and the third roller can rotate about a third rolling axis running parallel to the plane of extent. The invention further relates to an arrangement having at least two such running gears, wherein at least two such running gears are connected to each other.

A personal shopping cart, or trolley, to be used to transport purchased items, includes a wheeled base, a handle that extends and retracts, and multiple nesting bins or containers. The wheels and handle are such that the trolley can be easily pulled or pushed. The bins are attached to a frame allowing different vertical positions, enabling the bins to either nest into each other (for storage, minimizing its size), or to extend vertically for carrying merchandise. All bins, with the exception of the bottom bin, are removable from the frame.

A delivery dolly includes a carousel that is rotatably mounted on a support column. The carousel includes a recess on an underside of the carousel. A locking mechanism is biased toward a locked position. The locking mechanism includes a locking wheel on which the carousel rotates until the carousel reaches a preselected angular position. The recess aligns with the locking wheel at the preselected angular position and, due to a bias force, the locking wheel extends into the recess to inhibit rotation of the carousel until the carousel is spun manually, forcing the carousel to rotate and the locking wheel to retract until the locking wheel encounters the recess again.

A multi-axis support cart includes a base having a longitudinal axis and a second axis defining a first plane with wheels coupled to the base facilitating movement of the base along the first plane. Coupled to the base is at least one telescoping riser extending along a third axis orthogonal to the first plane. A support surface is coupled to the at least one telescoping riser and configured on a second plane parallel to the first plane with a piston coupled between the base and the support surface facilitating movement of the support surface along the third axis. A turntable coupled to the support surface receives a device/tool and provides rotational movement for the device/tool about the third axis.

A seat includes a seat plate, a first backrest support member, a second backrest support member, a third backrest support member, a first sliding sleeve and a second sliding sleeve. The second backrest support member is telescopically connected to the first backrest support member. The third backrest support member is telescopically connected to the second backrest support member and pivotally connected to the seat plate. The first sliding sleeve is disposed on the first backrest support member. The second sliding sleeve is disposed on the second backrest support member. The first backrest support member, the second backrest support member and the third backrest support member are able to slide with respect to each other to be folded or unfolded. The first sliding sleeve slides as the first backrest support member slides, and the second sliding sleeve slides as the second backrest support member slides.

A stroller includes a frame, a sliding member and a seat fixing base. The sliding member is rotatably connected to the frame. The seat fixing base is rotatably connected to the frame and slidably connected to the sliding member. When the frame is folded, the frame drives the seat fixing base to slide with respect to the sliding member.
