The invention relates to a refrigerating appliance (1) including a body (2) in which a refrigerating compartment (3) is defined and a door (4) connected to said body to open and close said compartment, and a height adjustable support assembly (10,10',100) connected to said body and/or said door. The refrigerating appliance (1) further comprises a rail (23a,23b;23a',23b') including a rack portion (21) attached to said body (2) within said compartment (3) and/or to said door (4), the rail extending substantially along a vertical axis. The height adjustable support assembly (10;10';100) comprises: a support member (11;11';11") to support items to be refrigerated/frozen; a height adjustment gear (15a,15b) rotatably connected to the support member (11;11';11"), the gear meshing with the rack portion (21) so that the support member can be vertically moved along the rail (23a,23b;23a',23b');a unidirectional stopper unit (19; 70) to regulate rotation of the height adjustment gear (15a,15b) when meshed with the rack portion (21), allowing an upward movement of the support member (11;11';11 ") along the vertical axis and blocking downward movements along the vertical axis; and a lever (50) coupled to the unidirectional stopper unit, the lever being apt to disengage the unidirectional stopper unit so as to allow a downward movement of the support member (11;11';11") along the vertical axis when operated. |
