Light duty X-frame cart

摘要

The X-frame cart has pivotally connected X-frame legs with front and rear wheels at terminal leg ends, a lower rear cross frame member between the wheels, and a lower framework with fore-aft-left-right frame members to define a rectangular openwork space. The lower framework is pivotally mounted to opposing X-frame members at the lower rear cross frame member. A flexible panel spans a portion of the rectangular openwork space. The panel is mounted on either the lower fore and aft frame members or on the left and right longitudinal frame members which define the rectangular or square openwork space. A pull bar pivotally mounted to the front end lower framework and the rear wheel permits the pull bar to move the cart fore-end towards the rear-end when the pull-bar is moved upward. The X-frame legs collapse towards each other. The cart has a chair hanger and an open-top bag.

主权项

1. A foldable light duty X-frame cart adopted to carry items such as light duty chairs, towels, blankets and food stuffs comprising:
an X-frame structure including opposing rigid side X-frame members, each x-frame member having a first elongated X-frame leg extending from an upper handle cart region to a lower forward wheel cart region and a second elongated X-frame leg extending from a lower rear wheel cart region to an upper forward-facing cart region, the first X-frame leg pivotally joined to the second X-frame leg at respective substantially mid-length regions of each X-frame leg; each first X-frame leg having a forward wheel system rotatably mounted near bottom portions of said first X-frame leg such that opposing first X-frame legs have forward cart wheels rotatably mounted thereon; each second X-frame leg having a rearward wheel system rotatably mounted near bottom portions of said second X-frame leg such that opposing second X-frame legs have rearward cart wheels rotatably mounted thereon; a lower rear cross frame member disposed about an axis of rotation of said rearward cart wheels; a lower framework defined by fore-frame, an aft-frame, and left and right longitudinal framework members which define a substantially rectangular openwork space, the lower framework pivotally mounted to said opposing X-frame members at said lower rear cross frame member; a flexible panel spanning a substantial portion of said substantially rectangular openwork space and mounted on said lower fore-frame and said lower aft-frame members; at least one pull bar having a forward end and a rearward end, the forward end of said pull bar pivotally mounted at a forward end of said cart at one of said forward wheel systems or at the bottom portion of said first X-frame leg, the rearward end of said pull bar pivotally mounted substantially near a longitudinal midsection of one said lower longitudinal framework members or near the rear of the lower framework member; a handle bar disposed at the upper handle cart region and joining opposing first X-frame legs thereat; an upper cross bar member joining opposing second X-frame legs at the upper forward-facing cart region; said cart collapsing into a compact form when the lower fore-frame member is moved upward such that it pivots about said lower rear cross frame member causing said pull bar to move said forward cart wheels towards said rearward cart wheels and further causing the first X-frame legs to pivot about its mid-region with respect to the second X-frame legs thereby collapsing said first and second X-frame legs towards each other.
