Abstract

The present invention refers to a lifting-lowering and sliding group (10) for door or window wings (102), comprising at least one carriage (11a, 11b) in turn comprising a support body (14a, 14b) which is provided with support and rolling elements (15a, 15b) and which is associable with a sliding guide (106) in a mobile manner in translation along the sliding direction (A) of a door or window wing (102), an attachment body (17a, 17b) to the wing (102) which is fixable to its lower crossbar (104) and which is associated with the support body (14a, 14b) in a mobile manner on a plane parallel to the lying plane of the wing (102) with a relative combined translation motion along the sliding direction (A) and along a direction (B) orthogonal to it for lifting and lowering the wing (102) with respect to the support body (14a, 14b), in which the carriage (11a, 11b) has an end associable with a manoeuvring mechanism (12, 13) of the relative displacement of the attachment body (17a, 17b) with respect to the support body (14a, 14b), wherein the manoeuvring mechanism is activatable by a control handle (105) associable to the wing, the group being characterised in that the support body (14a, 14b) of the at least one carriage (11a, 11b) comprises a guide body (19a, 19b) of elastic means (20a, 20b) acting between the support body (14a, 14b) and a counter element (21a, 21b) associable with the lower crossbar (104) of the wing (102), in which the counter element (21a, 21b) is associated with the guide body (19a, 19b) in a mobile manner in translation along the sliding direction (A) and along a direction orthogonal to it (B).
