  • Articulation having angle adjustable function
    Patent number: 7617569
    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.

  • Golf cart collapsible device
    Patent number: 7552931
    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.

  • Golf Cart
    Publication number: 20090079165
    Abstract: A golf cart includes an upper frame provided with a handlebar and a rotation articulation, a lower frame provided with an upper support seat and a lower support seat to support a golf bag for receiving golf clubs, and a link connected between the upper frame and the lower frame so that the upper frame and the lower frame are not located at the same line. Thus, the link connects the upper frame and the lower frame so that the rotation articulation on a lower end of the upper frame is not located at a central line of the lower frame and is deflected backward and upward to a rear side of an upper end of the lower frame, and a larger space is defined between the handlebar and a club head of each of the golf clubs.

  • Front Wheel Foldable Device for Golf Cart
    Publication number: 20090066056
    Abstract: A front wheel foldable device for a golf cart includes a main body, a wheel frame, a positioning member, a sleeve, a stop member, and an elastic member. Thus, the wheel frame is pulled outwardly relative to the main body so that the locking portions of the positioning member are moved to detach from the locking grooves of the main body respectively. Then, the wheel frame is rotated through ninety (90) degrees and is released, so that the post of the wheel frame is retracted into the main body by a restoring force of the elastic member, the locking portions are locked in the locking grooves respectively, the front wheel is turned from an upright state to a horizontal state, and the front wheel is parallel with and rested on the cart frame when the cart frame is folded.

  • Stroller having front wheel positioning device
    Patent number: 7258353
    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.
