Claim:
A supporting device for an inner supporting member of an electric household appliance, said supporting device comprising: a support including a first part securable in use to a fixed guide provided at an inner compartment of the electric household appliance, and a second part, opposite to and facing the first part, securable in use to a side edge of the inner supporting member of the electric household appliance, the second part of the support being movably carried by the first part in a relative sliding direction, the second part adapted to be perpendicular to a laying plane of the inner supporting member; and a releasable retaining element for blocking the second part with respect to the first in a plurality of different positions along said relative sliding direction, wherein the releasable retaining element comprises: a pin carried by the first part of the support and having a free end overhangingly protruding towards the second part of the support in a transverse direction perpendicular to the relative sliding direction; a first elastic member, the pin being slidable on the first part of the support against bias of the first elastic member in the transverse direction; a second elastic member; and a desmodromic sliding track along which the free end of the pin is movable, and the track including a slide that is slidingly carried against bias of the second elastic member by the second part of the support in the relative sliding direction between the second part and the first part of the support, the track being divided into a first and a second branches, integrally formed, respectively, within the second part of the support and within the slide, wherein the first branch of the track includes a plurality of first openings facing the second branch and a plurality of resting teeth for the pin, which are arranged in sequence along said relative sliding direction and aligned with an equal number of the first openings facing the second branch, and the second branch of the track is separated from the first branch by a wall of the slide having a plurality of second openings for the pin which are facing the first branch and are held by the second elastic member in an offset position from the first openings in the relative sliding direction.
