ABSTRACT:
An opening and closing system permits a drawer to be operated by pressing on a front panel of the drawer (e.g., in a hands-free manner). By way of example, the system includes a first sub-assembly coupled to the drawer and a second sub-assembly coupled to a drawer frame. A linear spring provides a tensioning force for operation of the drawer. The first sub-assembly includes a first pivot biasly coupled to the drawer, a fixed-length arm having a first end fixed to the first pivot and a second end coupled to a roller. The second sub-assembly includes first and second guide arms coupled to a second pivot, the first guide arm having an upper surface for engaging the roller when the drawer is being closed, the second guide arm having an arcuate-shaped region sized to receive at least a portion of the roller after the drawer is closed.
