  • Patent number: 8602424
    Abstract: There is provided, in combination, a collapsible walker and a collapsible basket. The walker includes a pair of spaced-apart, operatively interconnected frame members. The frame members each have an upper end for placing one's hand and a lower end spaced-apart from the upper end. Ground-engaging wheels are rotatably mounted to the lower ends of the frame members. A folding mechanism allows the frame members to be brought together for folding the walker. The collapsible basket includes a pair of spaced-apart, rigid end members, each being connectable with a respective one of said frame members. A flexible basket member extends substantially about, extends between and is supported by the rigid end members. The end members are moveable towards each other and the basket member thereby folds to collapse the basket when folding the walker.

  • Patent number: 8487214
    Abstract: A welding carriage has a frame that is adjustable in width and height and is guided by the sides of a workpiece. First and second wheel assemblies support the frame upon the workpiece, the first and second wheel assemblies forcibly engaging the sides of the workpiece for guiding the frame along a path substantially parallel thereto. The frame comprises two opposing lateral sides interconnected by a linkage therebetween. The linkage can be actuated to adjust a coarse width of the frame, dimensional variations being handles by biased guide wheels of the second wheel assembly. Each of the opposing lateral sides further has vertically adjustable leg posts for adjusting a vertical height of the frame.

  • 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.
