The invention provides a pre-fabricated cabinet frame structure (1) including two opposing side wall elements (2, 3) each having an inside surface (4, 4′), a front edge (5, 5′), a rear edge (6, 6′), a base portion (7, 7′), and a top portion (8, 8′). At least two spacer arms, moveable between a folded configuration and an extended configuration, are also provided. Each spacer arm is hingedly connected by wall hinges at one end to an inside surface of one side wall element, and at the other end to an inside surface of the other opposing side wall element. At least one spacer arm extends adjacent the front edge of each wall element and at least one spacer arm extends adjacent the rear edge of each wall element. The at least one spacer arm adjacent the front edge is offset from the at least one spacer arm adjacent the rear edge such that they do not interfere with each other in the folded configuration.

A cooking device according to the present invention may comprise: a frame forming a cooking chamber; and a rack support mechanism detachably installed to the frame and supporting a rack such that height of the rack can be adjusted.

The invention is a wheeled folding tray cart and method. The wheeled folding tray cart comprises a collapsible wheeled framework pivotally supporting a set of split shelves, each split shelf comprises a pair of half shelves. The wheeled folding tray cart moves between an open operating position wherein the set of split shelves are held in spaced-apart, stacked, horizontal orientation within the collapsible wheeled framework and a closed storage position wherein the collapsible wheeled framework is collapsed in manner to move each half shelf pair into an accordion-like, inverted “V”-shaped or accordion like configuration. An extension coiled spring attached to the collapsible wheeled framework assists in the movement of the wheeled folding tray cart between open operating position and the closed storage position. A sheath encloses at least a portion of the spring to provide resistance to the spring's movement to limit potential operator exposure to pinch injuries.

A storage device is provided including a support frame having a plurality of elongated support members and a stiffening bracket carried by the support members. An enclosure may be carried by the support frame. The enclosure may be foldable and have a fabric construction and may be detachably attached to the support frame. A plurality of closeable storage compartments may be provided in the enclosure. The storage compartments may contain items such as towels, clothes, shoes, lotion and other items used by a beachgoer or other user, at the beach or other location.

A foldable shelf convenient to transport and assemble, including at least two storage members and vertical rods installed on two sides of the storage members, where the vertical rods each includes a fixed rod relatively fixed to one side of the bottom storage member and at least one folding rod; a lower end of one folding rod adjacent to the fixed rod is hinged to an upper end of the fixed rod; the storage member at the bottom is disposed on an inner side of the fixed rod, two sides of each of other storage members are fixedly connected to sliding blocks, and the sliding blocks each sleeve the vertical rod and are capable of sliding along the fixed rod on the vertical rod and the folding rod; and a fastening device is disposed between the sliding block and the folding rod.

Provided is a wine rack having a mat, a first side wall, and a second side wall. The wine rack is configured to support a plurality of wine bottles between the first side wall and the second side wall. The wine rack is further configured to roll into a stowed position for storage, transportation, distribution, or advertising. Alternatively, the wine rack has a pair of scissor arms located between the first side wall and the second side wall such that the rack is configured to pivot between an extended position and a retracted position.
