ABSTRACT:
A pull down shelf assembly (20, 20a) for facilitating access to upper storage shelves (22, 22a). The shelf assembly includes a shelf guide track mechanism (24, 24', 24a, 24a') and the storage shelf (22, 22a) slidably mounted for movement between an extended position and a retracted position. A pantographic pull down mounting assembly (26, 26', 26a, 26a') coupled between a shelf mounting bracket (28, 28', 28a, 28a') and the track mechanism produces pantographic movement thereof between a deployed position, for increased access, and an elevated stored position. The pantographic assembly is mounted therebetween at locations producing near-horizontal pantographic movement of the track mechanism with the storage shelf carried thereby throughout an arcuate path between the deployed position and the elevated stored position. A spring biasing mechanism (38, 38', 38a, 38a') coupled between the mounting bracket and one of the arms biases the track mechanism toward the stored position. A shelf locking mechanism (42, 42', 42a, 42a'), positioned between the track mechanism and the storage shelf, locks the storage shelf in the extended position during movement of the track mechanism from the deployed position to the elevated stored position.
