Workstation and spring-assisted door therefor

This application relates to storage systems, such as tool storage systems for use by mechanics, service technicians and the like for storing tools and associated equipment. It is well known to provide such storage systems in the form of interconnectable modules, including a base unit or module, such as a tool cabinet mounted on wheels or casters (commonly referred to as a "roll cabinet"), and add-on storage modules which can be mounted on the base module and/or on each other for building a multi-faceted storage system. A storage riser for mounting atop a work surface has an open-front wall structure including rear, side and top walls and a bifold door assembly for closing the front opening. The door assembly has an upper panel hingedly connected to the front of the top wall and a lower panel hingedly connected to the bottom of the upper panel for pivotal movement between a vertical, unfolded, closed position and a non-vertical, folded, open position disposed in the storage compartment adjacent to the top wall. Coupling brackets respectively project inwardly of the compartment from the opposite sides of the lower panel adjacent to its upper end, the brackets respectively carrying guide rollers which respectively roll in channel tracks on the side walls. Opening of the door assembly is assisted by gas springs, respectively disposed adjacent to the side walls and having cylinders pivotally coupled to the coupling brackets and rods pivotally coupled to the side walls adjacent to the lower end of the front opening.
