Abstract
A filing cabinet has at least one drawer or file hangers associated with the drawer that can be selectively lifted from a first elevation to a second elevation when the drawer has been moved to an open position with respect to the frame of the filing cabinet. The filing cabinet includes the frame; drawers, including the drawer that can be lifted; and a drawer-opening assembly that movably connects the drawer to the frame. When the drawer is opened, it can be disengaged from the drawer-opening assembly and lifted to a position that is more accessible to users of the filing cabinet. The drawer can be lifted by force supplied by the user, by mechanical or electrical devices, or by a combination of the foregoing. Examples of the mechanical or electrical devices include pneumatic pistons, hydraulic pistons, spring-activated structures, and electric motors. The bottom drawer or a number of bottom drawers of the filing cabinet can experience the lifting motion. Lifting the drawers in this manner makes the drawers more accessible and reduces the physical strain that can be associated with use of conventional filing cabinets.
