A storage rack contains: a rectangular platform, two support feet, a rectangular plane, two long fringes, two short fringes, four circular orifices, four oval orifices, and two grips which. The two support feet are connected on the rectangular platform, and a respective support foot has a first inward bending portion and a second inward bending portion which are formed on two free ends of two tops of the respective support foot. Each of the first inward bending portion and the second inward bending portion has an arcuate face and an insertion, the arcuate face corresponds to a respective oval orifice of a respective long fringe of the rectangular platform, and the insertion corresponds to a respective circular orifice of the respective long fringe of the rectangular platform, such that the insertion is rotatably accommodated into the respective circular orifice to expand or retract the respective support foot freely.

Examples provide a height adjustable tray including a service surface for moving one or more items from a first height near the top of a display case down to a lower height within reach of a user in a seated position or otherwise unable to reach a top surface of the display case. The tray is connected to a set of one or more support arms. A gearing mechanism moves the set of support arms along a range of motion to lower the tray from the first height near the top of the display case to a position in front of the display case at a second height. The tray remains in a horizontal orientation substantially parallel to the floor or ground surface as the tray moves through the range of motion. An operating mechanism controls movement of the tray along the range of motion.

Disclosed is a fully articulated extendable wall-mounted shelf, including: a back plate; first side plate capable of rotating relative to the back plate to be flush with and/or attached to the back plate, the first side plate assembly including first connecting plate, first extendable plate and first fixing plate, the first extendable plate being capable of being extendably adjusted relative to the first connecting plate, the first fixing plate being rotatably connected to the first connecting plate; and second side plate assembly capable of rotating relative to the back plate to be flush with and/or attached to the back plate, the second side plate assembly including second connecting plate, second extendable plate and second fixing plate, the second extendable plate being capable of being extendably adjusted relative to the second connecting plate, the second fixing plate being rotatably connected to the second connecting plate.

The invention involves a system and method for retrofitting a cabinet to accommodate wheelchair accessibility, which employs a retractable shelf configured to expand and retract for concealing and revealing a wheelchair accessible space. In exemplary embodiments, the retractable shelf is situated between the left panel and the right panel and in proximity to a floor space of the cabinet, wherein the retractable shelf is configured to retract and expand to reveal or conceal the wheelchair accessible space. The retractable shelf may include a plurality of panels hingedly coupled together, such as a posterior panel and an anterior panel, some of the panels configured to fold, such that at least one of the plurality of panels folds on top of the posterior panel in order to reveal or conceal the wheelchair accessible space. The invention allows retrofitting of any type of cabinet for wheelchair accessibility.

A step unit including a vertical frame and a plurality of linkages pivotally attached at different heights to the vertical frame by one end of each of the linkages, to provide lateral rotation to the linkages. A leg frame, with at least one leg, is pivotally attached to the opposite end of each linkage whereby laterally translating the leg frame simultaneously pivots the linkages from a first, vertical position to at least one second, horizontal position.

A shelving system includes first and second side members. A cross member is coupled to the side members. A guide member is coupled to the cross member such that the guide member is movable relative to the cross member. A container including a rail is coupled to the guide member. The rail includes a first locking element and a second locking element that is connected to the first locking element. The container includes a handle having a third locking element that engages the first locking element. The locking elements are configured to move the container between a first orientation in which the container is provisionally fixed to the guide member and a second orientation in which the container can translate relative to the guide member.
