Disclosed is a cart-attachable mobile golf bag, in which the golf bag is configured such that a head cover is detachably attached to an upper portion of a bag body storing golf clubs therein, and the golf bag is attached to a cart in a docking manner by engagement between a docking recess of the golf bag and a docking block of the cart inserted into the docking recess in a one-touch manner, thus making it possible that the golf bag is simply and firmly attached to the cart without requiring any separate tying process. In particular, the golf bag has a hard-shell structure, thus being safe even without requiring a separate wrapping cover when transported by air while being excellent in durability, and further the golf bag provides various storage spaces for storing various equipment other than golf clubs, thus being excellent in use efficiency.

An example cart inventory system and associated methods are described. The example cart inventory system includes a cart and a detection system. The cart includes a frame, and a shelf movably mounted to the frame and configured to be positioned between an extended position and a folded position. A top surface and a rear surface of the shelf include first and second identifiers, respectively. The detection system is configured to detect the first identifier when the shelf is in the extended position and detect the second identifier when the shelf is positioned in the folded position. In the extended position, the top surface is oriented upwards relative to horizontal and the rear surface is disposed against the frame. In the folded position, the rear surface is oriented upwards relative to horizontal.

A golf cart with front and rear wheels capable of being unfolded and folded synchronously includes an upper frame module, a lower frame module, a handlebar module, a front wheel module and two rear wheel modules. The upper frame module is mounted on the lower frame module and is able to rotate with respect to the lower frame module under the action of force. The front wheel module is mounted at a front end of the lower frame module and is able to rotate with respect to the lower frame module under the action of force. The two rear wheel modules are mounted on left and right sides of a rear end of the lower frame module respectively. The handlebar module is mounted at an upper end of the upper frame module through a lock mechanism.

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.
