Abstract:
An overhead door swingably secured to inner lateral wall surfaces of a cabinet by means of a pair of dampers each having a rotary shaft and a pair of stays such that the rotary shaft of each of the dampers is rigidly secured to one of the inner lateral wall surfaces of the cabinet and a base end of a corresponding one of the stays is rigidly fitted to a main body of the damper while a front end of said corresponding one of the stays is pivotably fitted to an inner surface of the door at a lower edge thereof, characterized in that said door is provided on the inner surface thereof with a pair of slide rail assemblies supported on the inner surface of the door and extending longitudinally from adjacent the lower edge of the door to adjacent an upper edge of the door, each slide rail assembly comprising a relatively long outer rail and a relatively short inner rail slidably engaged with each other, said inner rail being pivotably secured at an upper end to a front edge of a roof wall of the cabinet by means of a hinge, so that the door can be swung open or closed as a combined effect of slewing and sliding motions and, when fully opened, said door being placed on the roof wall of the cabinet, and a pair of stay holding tension springs, each spring being connected between a point upwardly and forwardly displaced from the base end of a stay on a corresponding one of the inner lateral wall surfaces of the cabinet and a point in a middle portion of the stay, in order to urge the outer rails and the door upward relative to the inner rails.
