  • Patent number: 6302430
    Abstract: A foldable golf cart includes a main support rod, a pair of wheel support rods, a connecting members, two connecting rods and a handle. The wheel support rods are pivoted to an intermediate portion of the main support rod, and each connected to a wheel. The connecting member is connected to an upper end of the main support rod. The handle is pivoted to an upper end portion of the main support rod. The connecting rods are each pivoted to the handle from one end, and pivoted to a respective one of the wheel support rods from other end. The handle has hooked portions separately engaging a depressing block of the connecting member. The handle is pivoted down to a folded position; thus, the connecting rods will at the same time move the wheel support rod to a folded position. The handle is pivoted upwards to an upright unfolded position; thus, the connecting rods will move the wheel support rods to an unfolded position.

  • Patent number: 6283496
    Abstract: A collapsible carrier suitable for transporting a load over rugged terrain which includes a support frame assembly formed by at least a pair of spaced apart side frame members located on opposite sides of a longitudinal central axis of the frame. Cross frame members connect the side frame members to define a cargo bed. A pair of wheels located on opposite sides of the cargo bed are each individually supported by support members mounted on a pivot axis which is affixed to opposite sides of the side frame members and displaced laterally outwardly from the side frame members. The wheels are thus pivotable about these axes from a use position, wherein the wheels are parallel to each other, and disposed on opposite sides of the cargo bed to a storage/backpack transport position wherein the wheels are folded over one another and over said cargo bed. The side frame members are formed of collapsible sections that are either telescoped together or pivotally connected to each other.

  • Patent number: 5857684
    Abstract: A first frame member and a second frame member are pivotally joined at respective ends thereof for movement towards each other into a collapsed disposition and for movement away from each other into an erected condition wherein the members are at right angles to each other. One of the members supports to each of its sides an articulating wheel support and wheel and carries within its hollow a slide which is connected by pivots to each of said wheel supports and by pivoting straps to the other frame member so that when the frame members pivot apart the wheels move out and so that when the frame members pivot towards each other the wheels are drawn in so that the entire device assumes a collapsed condition. The frame members carry supports for a golf bag and may carry a battery tank (for a battery when the wheels are driven by motors that are battery powered) storage containers, seats, an umbrella stand and similar articles useful to a golfer. A number of wheel support configurations are provided.

  • Patent number: 5853189
    Abstract: The invention is a cart assembly having an upper and a lower deck whose body may be assembled in a single procedure using only one hand and whose body including the wheels can collapse to fit behind the driver's seat of a standard cab version of any size pickup truck. Specifically, a plurality of spacing members rotatably connected between the upper deck and lower deck rotate to alternately collapse and expand the cart. The cart is held in a fixed position by a brace member disposed diagonally between the upper deck and lower deck in the expanded position of the cart, and which is disposed in parallel to the upper deck and lower deck when the cart assumes its collapsed position. The brace member fixes the relative positions of the upper deck and the lower deck as the brace member has a length (and thus radius of curvature) unequal to the length (and thus radius of curvature) of the spacing member.

  • Patent number: 5836595
    Abstract: A stepladder/handtruck combination is used as a stepladder in a first position and as a handtruck in a second configuration. A plurality of steps are positioned to move between horizontal positions in the stepladder configuration and positions substantially parallel to the frame when the combination is being used in the handtruck configuration. A pair of wheels provides for convenient transport and a support plate used in the handtruck configuration is pivotal about a frame member and assumes a position parallel thereto when the combination is stored. Links connect the steps to the frame and provide for displacement of the steps when the combination is moved between the stepladder and handtruck configurations.

  • Patent number: 5803471
    Abstract: The subject invention is a lightweight, foldable, collapsible dolly which is to be used to move exterior heavy objects from one locale to another that is capable of being folded to a substantially shortened, flat arrangement facilitating storage in confined quarter locations such as beneath the seat or within an overhead bin of an airplane or train. The collapsible dolly includes a pair of wheels, each of which is movable from the flat arrangement to a transverse position relative to the support frame of the collapsible dolly. With the wheels located in the flat arrangement, the dolly can be rolled by the wheels on a supporting surface. The moving of the wheels into the transverse position occurs automatically during movement of the platform from its stowage position to an outwardly extended position which is the loading position of the platform.
