  • Patent number: 8393633
    Abstract: A golf bag cart foldable device includes a bottom cart stand having a rear wheel frame at each side to link a rear wheel. The bottom cart stand has a bag base to link a front wheel. An upper cart stand is in pinned connection with the bottom cart stand. A linkage set, including plural linkages, forms links between the upper cart stand and the bottom cart stand and between the upper cart stand and the rear wheel frame. A folding joint enables release of the folding joint first. By the link between the linkage set and the rear wheel frame, simultaneous unfolding or folding of the upper cart stand, the bottom cart stand and the rear wheels can thus be accomplished. The folding joint is secured to have the upper cart stand and the bottom cart stand locked to each other, to achieve handiness in use.

  • Patent number: 8205723
    Abstract: A brake apparatus for carts with three or more wheels such as golf bag carts, baby strollers and the like includes a hand brake control assembly fixed on the cart frame and having a body and a lug in pinned connection with the body. Brake activation can be done through a pull on the lug. On the other hand, brake release is achieved by pressing springy pushbuttons on both sides of the lug to escape the clipping pin from the indent. A brake pole set, fixed on a rear wheel axle tube, is capable of offering a buffer mechanism, which avoids potential destruction to the wheel. A brake wire enables easy operation and achieves an automatic lock during braking, which substantially prevents the lapse of releasing the brake by the user.
