US Patent 10182650 One piece collapsible shelving unit with vertical divider structure

A shelving unit movable between a shelf-supporting condition and a collapsed condition includes first and second side support frames pivotally connected to a rear support frame. At least two shelves are pivotally mounted to the rear support frame for movement between a horizontal position supported on the first and second side support frames, and a vertical position removed from the first and second side support frames. At least one divider is pivotally mounted to one of the at least two shelves between a vertical position between the at least two shelves and a horizontal position folded against the one of the least two shelves. The first and second side support frames are folded forwardly of the at least two shelves in the vertical position thereof, and the second side support frame is also folded forwardly of the at least one divider folded against the one of the at least two shelves to form a compact folded, layered arrangement so that the shelving unit is easy to store and transport.
