Abstract: A three wheeled cart is equipped with an inclined gas cylinder holding rack, which is configured to accept a set of two such cylinders, and a towing drawbar, pivotally connected for vertical movement, is connected to the steerable front wheel. The cart is tipped up to reorient the cylinder holding rack vertically, in which position the drawbar length contacts the ground to act as a prop, supporting the cart in the reoriented attitude so as to facilitate the transfer of standing gas cylinders into the vertically positioned cylinder holding rack.

Abstract: A toy convertible between a doll walker and an activity play board includes a base having at least one wheel, and activity components and a seat formed in a first main surface of the base. A pair of bosses project laterally from the sides of the base, and a pair of wheeled legs attach to the base by engaging the bosses in boss cavities and with a fastener. By selecting the appropriate boss cavities, the base can be either horizontally oriented or inclined relative to the horizontal.
