Abstract: An articulation includes a first shell, a second shell, a gear wheel, a push button, and an elastic member. Thus, the second shell is unlocked from the first shell by pressing the push button so that the second shell is rotatable freely relative to the first shell so as to adjust the angle between the second shell and the first shell. In addition, when each of the limit plates of the gear wheel is separated from a respective limit slot of the second shell, the gear wheel is stopped by the second shell and is not pushed by the elastic member, so that the second shell is rotatable freely relative to the first shell through a larger angle without having to press the push button successively, thereby facilitating a user adjusting the angle in an energy-saving manner.

Abstract: A golf cart collapsible device includes a frame including an upper frame and a lower frame, a foldable articulation mounted on a mediate portion of the lower frame for folding the lower frame, two rear wheel frames mounted between the lower frame and two rear wheels, a collapsible articulation mounted between the lower frame and a front wheel frame for folding a front wheel, and a pull bar mounted between the collapsible articulation and the two rear wheel frames. Thus, the pull bar is connected between the collapsible articulation and the two rear wheel frames, so that when the front wheel is folded, the pull bar is driven to move the two rear wheels simultaneously so as to fold the front wheel and the two rear wheels simultaneously by connection of the pull bar.

Abstract: A stroller includes a main frame, a pedal, a front wheel frame, and a positioning device. The positioning device includes a lower cover, an upper cover, a rotation knob, and a locking rod. Thus, the front wheel frame is locked to and unlocked from the main frame by moving the drive plate of the rotation knob, so that the positioning device is operated easily and rapidly. In addition, when the positioning device is unlocked, a click sound is produced so as to notify the user that the positioning device is unlocked and the front wheel frame is rotatable relative to the main frame freely, thereby facilitating the user judging the state (locked or unlocked) of the front wheel frame.

Abstract: A powered mechanism for a universal golf cart includes a transmission device, and a fixing device. The transmission device includes a housing assembly for mounting a motor, a battery unit, a control circuit board and a drive shaft. The drive shaft is connected with a wheel of the golf cart. The fixing device has a first portion secured to a foot tube of the golf cart and a second portion mounted on the drive shaft. Thus, the powered mechanism converts a traditional powerless golf cart into a motorized golf cart easily and rapidly.

Abstract: A detachable device for an auxiliary wheel of a golf cart includes a main body, an auxiliary wheel unit, and a drive handle. The auxiliary wheel unit includes a wheel support rack, and auxiliary wheel and a plastic block. The auxiliary wheel unit is mounted on and detached from the main body by the pivot action of the drive handle, thereby facilitating a user mounting and folding the auxiliary wheel unit. Thus, the detachable device is operated to mount and fold the auxiliary wheel unit easily, rapidly and conveniently, thereby facilitating the user operating the detachable device.

Abstract: A tire for a golf cart includes an inner tire, and a thin outer tire mounted around the inner tire. The inner tire made of EVA solid foam material co-operates with the thin outer tire having a plurality of protruding bosses to construct a solid composite tire, so that the tire has a light weight, needs not to be inflated and has a better shock-absorbing effect. In addition, the pointed cylindrical shaped protruding bosses of the thin outer tire can be extended into the muddy or snowy ground to provide an excellent grip effect, so that the golf cart can be moved smoothly and conveniently. Thus, the tire has an excellent ground grip effect, so that the tire is available for the muddy or snowy ground.
