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.

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 hand cart includes a wheel frame, a transverse rod, a wheel, and a quick release device. The quick release device includes a locking member, a press button, an elastic member, and a cover. Thus, the locking member and the elastic member are made easily and conveniently, thereby decreasing costs of fabrication. In addition, the wheel axle of the wheel is mounted on and detached from the frame body of the wheel frame easily and rapidly.

Abstract: A golf cart front-wheel collapsing device includes two parallel lower tubes, two stationary annular gears, a rotary cylindrical gear, a switch and a front wheel. The lower tubes are fixed under a golf cart frame, having a lower end combined with each stationary annular gear, with the cylindrical gear located between the stationary annular gears, and with a coil spring located respectively between each stationary annular gear and the cylindrical gear. The switch is positioned in one of the stationary gears for securing other components in place and operated to engage and disengage the stationary gears with and from the cylindrical gear, letting the front wheel removably combined with the cylindrical gear able to be expanded or folded for collapsing this device, also adjusting the front-wheel's angle to suit to users of different heights.

Abstract: An adjustable front fork blade for a stroller includes a sleeve, a base movably mounted in the sleeve, and a connecting tube mounted between the sleeve and the base. Thus, the front fork blade has an adjustable length so that when two front fork blades are mounted on a front wheel, the length of each of the two front fork blades can be adjusted to match each other so as to calibrate and center the position of the front wheel, thereby preventing the front wheel from being oscillated or vibrated due to deflection.

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 third wheel collapsing device for a golf club cart includes a third wheel support frame having a U-shaped frame fixed pivotally with a third wheel and a hollow support arm fitted therein with a fit block. The support arm and the fit block respectively have insert holes and connecting holes. A support base assembled on the support arm has a pivotal shaft under the bottom and a threaded hole before the pivotal shaft for receiving an elastic lock member, which has an engage rod biased by a compression coil spring and controlled by a user. The support base has a fastening frame fixed with the lower end of the main frame of a golf club cart. When the engage rod is pulled and removed from the first insert hole of the support arm and the first connecting hole of the fit member, the third wheel support frame can be transversely collapsed.

Abstract: A third wheel collapsing device for a golf club cart includes a third wheel support unit consisting of a connect base having a fitting member with an upper inclined surface, and a lock block on the upper inclined surface. A spring chamber is continually formed in both the fitting member and the lock block for receiving a spring therein. A control rod is movably fitted in a center hole of both the fitting member and the lock block and through the spring, and has its lower end pivotally connected with an eccentric plate. The eccentric plate is swung up or down to move down or move up the control rod so that the lock block is also moved down to alters its position a little to firmly contact with an inner surface of a main frame of a golf club cart or to separate from the main frame, assembling or disassembling the third wheel support unit with or from the main frame.

Abstract: A stator winding structure of a motor or a generator includes plural separate different-shaped rod conductors combined to form a collective winding structure to take the place of a conventional winding structure which has a coil wire wound continuously. The different-shaped rod conductors can be designed in shape to match with the sizes of the coil slots to increase a slot occupied rate of the conductors and to prevent the conductors from bent during the coil winding process. The stator winding structure is especially applicable to a motor or a generator with large power and difficult in multi-electrode winding, facilitating winding and enhancing a slot occupied rate of the conductors and also reducing copper loss during output of large current.

Abstract: A golf-cart upper support frame includes an upper and a lower cap, two slide blocks, two movable wings and a band unit. The two slide blocks are movably combined the upper and the lower cap, having respectively a shaft base for a shaft to insert and also in each wing under the shaft base. Each wing has a concave surface in a front side for receiving a club bag. The band unit is combined with the two wings to bind a club bag resting on the two wings adjustable in their locations by the slide blocks so that club bags of various sizes may be carried resting on the upper support frame adjustable in its size. So a club bag carried by the golf cart with the upper support frame might not sway around, even if the golf cart should run on a non-flat rough ground.
