Abstract:
1. A foldable light duty cart, comprising: a main-frame structure including opposing rigid main-frame side frame members with at least one rigid main-frame cross bar member extending between the main-frame side members; a wheel system rotatably mounted near a respective bottom portion of each of the main-frame side members; a panel attached to and extending between the main-frame side members, the panel being sufficiently rigid to function as a table top surface when the main-frame structure is in a generally horizontal orientation; an upper frame stand which is pivotally attached to the main-frame side members, including opposing rigid upper frame stand side frame elements and at least one rigid upper frame stand cross bar element extending between the upper frame stand side frame elements; a lower frame stand which is pivotally attached to the main-frame side members, including opposing rigid lower frame stand side frame elements and at least one rigid lower frame stand cross bar element extending between the lower frame stand side frame elements; a lower swivel lock having body, a frame channel and channel side walls, the body pivotally attached to one of the main-frame side frame members and fixedly attached to an adjacent one of the lower frame stand side frame elements, the frame channel capturing the main-frame side frame member therein when the lower frame stand is substantially perpendicular to the main-frame side frame member in an extended position, and, when the main-frame side frame member is not captured in the frame channel, the lower frame stand is capable of moving to a collapsed position near the main-frame side frame member; an upper lock system between one of the main-frame side frame members and an adjacent one of the upper frame stand side frame elements, the upper lock system configured to selectively secure the upper frame stand in an extended position relative to the main-frame structure such that a load can be supported by the upper frame stand when the cart is in an upright position; a lower lock system between one of the lower frame stand side frame elements and an adjacent one of the main-frame side frame members, the lower lock system configured to selectively maintain the lower frame stand side frame element in an extended position with respect to the main-frame structure; wherein the channel side walls define two inwardly-extending detents on opposing sides of the frame channel to capture the mainframe side frame member within the frame channel.
