Sliding shelves for refrigerators and freezers

Sliding shelves for refrigerators and freezers comprising:

• a front base (4a), substantially rectangular, partially covered by a front frame (2a) provided with at least two lateral protuberances (3a/3b);
• a rear base (4b), substantially rectangular, partially covered by a rear frame (2b) provided with at least one lower recess (5);
• lateral support guides (1) attached to inner walls of such refrigerators and freezers and each provided with a track (20) and a plurality of fitting means (6), central fittings (8) and a resilient locking means (7), being shaped so as to provide support, fitting, and rotation of the rear frame (2b) and also to allow the essentially longitudinal movement of the front frame (2a),
• characterized in that the locking means (7) is resiliently adapted to lock the respective protuberance (3a) of the front frame (2a) in the end fitting (40) of the lateral support guides (1) to prevent the front frame (2a) from moving along the track (20) of the support guides (1) when the shelves are arranged in an extended position,
• wherein the locking means comprises a resilient arm (34) that is coupled to the track (20) and is arranged upwards at an angle, relative to the track (20), to form an incline ramp (35) that leads to the end fitting (40), and
• wherein the resilient arm (34) further comprises an end (36) that resiliently blocks the protuberances (3a) in the end fitting (40), and a handle (32) that is movable to cause the end (36) of the resilient arm (34) to be temporarily moved downwards a sufficient amount to enable the protuberance (3a) to leave the end fitting (40).
