An upper back frame member is pivotally connected at one end to the upper end of the frame and is pivotally movable from locked positions parallel to the frame to an extended 90.degree. angle positions. The pivotally connected end is spaced a short distance from the end of the frame so that when the frame is inverted, an angled support provides a freely supported ladder. The frame member also has lower wheels and an extended support foot to be used in the hand truck mode.

Abstract: A cart convertible between a chair position and a bed position includes a horizontal seat frame pivotally coupled to a leg rest frame, a back frame, and four depending legs. The forwardmost pair of the depending legs and the back frame are coupled by an adjustment means for simultaneously raising the forward pair of legs and lowering the back frame toward a horizontal position thereby facilitating rolling the cart onto a raised platform having limited vertical clearance such as onto the loading gate of a station wagon. The rearward most pair of the depending legs can also be raised toward a horizontal position thereby facilitating positioning of the entire cart on the raised platform.

Abstract: An assembly kit comprising primary, secondary and intermediate sub-frames of tubular material which are all telescopically connectable to each other for erecting demountable frame structures.Each primary sub-frame has two side members and two cross members connected to the side members at positions spaced from the ends of the side members by a fixed distance. Two pairs of legs, having a length equal to the fixed distance, project respectively from the junctions of the side members and the cross members to one side of the side members.Each secondary sub-frame has two "L"-shaped side members and two cross members connected, respectively to the junctions of the arms of the "L"-shaped side members and at positions spaced by said fixed distance from the free ends the long arms of the "L"-shaped side members. The "L"-shaped side members are of tubular material which is a sliding fit on the tubular material of each primary sub-frame and have short arms equal in length to the fixed distance.

Abstract: A convertible golf cart which can be wheeled over a golf course carrying golf equipment and can be readily disassembled for transportation and storage. Detachable wheels and a retracting-removable handle and support strut serve to convert the golf cart from its operating condition to a storage and transport condition.

Abstract: A convertible ladder-carrier vehicle assembly includes a pair of parallel tubing elements connected by at least four transverse tubing elements. A second pair of tubing elements are positioned slidably within the first pair. Both pairs of tubing elements have aligned apertures. At least one resilient member having a hook element at each end is secured between the first pair of tubing elements detachably within the aligned apertures of the first and second pairs to thereby maintain the second pair of tubing elements in fixed relation to the second pair. A wheel assembly is detachably connected to each side of the first pair of tubing elements, journalled in intermediate transverse tubing elements.

Abstract: Tubular assemblies are interpivotally connected so as to form a stable seat when the assemblies are pivoted into an expanded position but form a wheeled carryall when in the collapsed position. One assembly cooperates with the other assemblies to provide a seat back when in the expanded position and likewise provides a gripping handle for manual movement when the assemblies are in the collapsed position. A second of the assemblies has wheels attached thereto which are pivoted out of engagement with the surface when in the expanded position but pivoted so as to provide wheeled engagement with the surface when the assemblies are interpivotally collapsed. The third assembly cooperates with the wheeled assembly to provide the seating arrangement in the expanded configuration and the carryall portion when in the collapsed configuration.

Abstract: A baby carrier which can be converted into an infant's stroller comprising first and second tubular frame members which are bent to form a three-sided rectangular shaped opening in order to support a baby seat. The extending ends of the first and second tubular members are connected to articulated joints so that parallel spaced apart front and rear legs can be connected to the tubular members. At the ends of the legs are provided wheels so that when the legs are opened to their fully extended position, they form a stroller for the seat. One of the tubular members includes loops which are formed as handles at the rear portion of the seat. A shoulder strap is also provided as well as a back rest which spans between the ends of the tubular members adjacent to the articulated joints.

Abstract: A stepladder with a sturdy plate mounted on its top surface and a pair of wheels mounted near the top of the ladder is provided so that upon folding the legs together and inverting the ladder, it becomes a dolly which rides on said wheels and employs the plate as a carry plate. Additional wheels or casters are added to the other end of the ladder to convert same to a wheeled flat bed.
