A carrier device and a stowing method are disclosed. The rear wheel frame is disposed on the front wheel frame. The front wheel is disposed on a first end of the front wheel frame. The rear wheels are disposed on two ends of the rear wheel frame. The upper frame is disposed on a second end of the front wheel frame. The upper stoppers are disposed on the handle frame linkage, the upper frame or the handle frame. The carrier device has a stowing state including a stowing position, in the stowing position, a plane formed by the front wheel and a plane formed by one of the rear wheels are substantially perpendicular to each other, and the upper stoppers are disposed on two sides of the plane formed by the front wheel respectively. This disclosure has the advantages of easy folding and stowing.

A rear wheel interlock folding mechanism of a golf bag cart is revealed. An upper frame is fixed on an upper-frame connecting rod connected to a lower frame. A rear-wheel connecting rod is fixed on the lower frame and behind the upper-frame connecting rod. A rear-wheel set is set on each end of the rear-wheel connecting rod. The rear-wheel set includes a fixing base fixed on the rear-wheel connecting rod, a bending base pivotally connected to the fixing base, a rear wheel pivotally disposed on the outer end of the bending base, a rotating seat fixed on the upper-frame connecting rod and a link between the bending base and the rotating seat. Thereby the bending base is also moved to drive the rear wheel moving close to the lower frame when the upper frame is folded toward the lower frame. Thus the golf bag cart is folded conveniently.

A stall and tack cart for transporting livestock is provided. The livestock stall and tack cart generally incorporates telescoping members and stall carriers protruding vertically therefrom. The telescoping members allow for a length of the livestock stall and tack cart to be adjusted such that the stall carriers may hold one or more livestock stalls securely while the stall and tack cart is in motion. The devices and methods provided have the advantages of being as durable and capable of carrying heavy loads as currently existing livestock transportation solutions, but allow equipment for one or more livestock animals to be quickly and easily transported, for example, from a waiting or confinement area to an exhibition space, including through crowded, obstructed, or tight passages.

A push cart, including: a frame, a rear wheel assembly, a front wheel assembly, a connection rod linkage. The frame includes an upper frame and a lower frame, and the upper frame is disposed on the lower frame. The rear wheel assembly is movably disposed on the lower frame or the upper frame. The front wheel assembly is disposed on the lower frame. The frame is connected to the rear wheel assembly via the connection rod linkage. The rotation of the upper frame or the lower frame drives the connection rod linkage to flatten the rear wheel assembly with the upper frame or the lower frame, or to unfold the rear wheel assembly.

A wheeled cart includes a number of unique methods to synchronously stow all of the rear wheels of a fold flat, compact wheeled cart device without removing any of the wheels themselves and the innovations are applicable to cargo carriers, golf bag carts, trolleys, baby strollers, and other devices for moving cargo. In alternative designs, the folding motion of either the forward wheel frame, or the swiveling motion of the rear wheel frame, or both, synchronously setup or stow the cart's at least two rear wheels to achieve an ultra-thin stowed profile, orienting all the cart's wheels in a co-planar stowed relationship, closely parallel with all other parts.

A container moving assembly includes a frame with a drive wheel pivotably attached to the frame about a steering axis. A pair of guide wheels are rotatably attached relative to the frame opposite the drive wheel. A platform lifting assembly is pivotable relative to the frame and includes an engagement platform for supporting a container.
