Abstract: A hinge unit for hopper/awning window units (1), the window unit comprising a fixed frame (2) and a sash (3) capable of rototranslation about at least a first connecting point (F1) between a window unit (1) closed position and an open position; there being inserted between the fixed frame (2) and the sash (3) on both sides a pair of hinge units (4), each comprising: a supporting and guiding element (5) integral with the fixed frame (2); an arm (6) one end of which pivots at the sash (3); a first slide (7) slidably positioned along the supporting element (5) and forming the first connecting point (F1); connecting rod means (8, 9) connecting the first slide (7) to the arm (6) and designed to allow rototranslation of the arm (6) away from and towards the supporting element (5); a joint rod (10) between the arm (6) and the supporting element (5), its ends respectively pivoting at a distal point of the supporting element (5) and at the arm (6), so as to form a second connecting point (F2); there being adjusting me

Abstract: An accessory for profiles used for making frames for sliding windows or doors comprising, amongst other things, a fixed frame formed by two crosspieces and two stiles; the profile forming the first lower crosspiece comprises two sliding tracks, parallel with one another, presented by a lower base body, and heat insulation elements; this profile having an element for connecting and joining two halves of the profile, transversally separate relative to the length of the tracks and together forming the whole of the lower crosspiece; this connecting and joining element also has heat insulation properties.

Abstract: A profile for making frames for sliding windows or doors comprising, amongst other things, at least one fixed frame formed by two crosspieces and two stiles; a profile, forming at least a first lower crosspiece, comprises two sliding tracks, parallel with one another, and made from a lower base body; the profile forming the lower crosspiece is divided, transversally, into two halves substantially equal and associated, at respective ends, with a matching element for connecting and joining the halves; the connecting and joining element therefore forming the central portion of the lower crosspiece and having heat insulation properties; the present invention also relates to a method for making the profile and a sliding window or door obtained with the profile.
