Hinge for doors or windows

Abstract

Described is a hinge for doors or windows comprising: a first fixed body (5) associated with a fixed frame (1) and having a first axis (X1) of fixed articulation and a slot (6) made parallel to the axis (XC) of longitudinal extension of the first fixed body (5); a second movable body (7) connected to a movable sash (2); a first lever (8) having a first end articulated to the first fixed body (5) about the first axis (X1) of fixed articulation, a second end articulated to the second movable body (7), defining a second axis (X2) of articulation, and an intermediate zone; a second lever (9) having a first end articulated inside the slot (6) of the first fixed body (5) to define a third slidable axis (X3) of articulation, a second end articulated to the second movable body (7) definng a fourth axis (X4) of articulation and an intermediate zone; the first (8) and the second (9) levers are articulated to each other in the corresponding intermediate zone to define a fifth axis (X5) of shared articulation; means (10, 11) for adjusting at least one between the first axis (X1) of articulation and the third slidable axis (X3) of articulation along at least a first horizontal axis (XR1) parallel to the axis (XC) of longitudinal extension of the first fixed body (5) or a second horizontal axis (XR2) perpendicular to the axis (XC) of longitudinal extension of the first fixed body (5); the adjustment means (11) are interposed between the first end of the second lever (9) articulated inside the slot (6) of the first fixed body (5) and the first fixed body (5) for adjusting the position of the third axis (X3) of articulation along the second horizontal axis (XR2) perpendicular to the first horizontal axis (XR1), in both directions.

Description

technical field [0001] The present invention relates to hinges for doors or windows. [0002] More specifically, the hinges referred to are so-called "concealed" hinges, that is to say, hinge models that are mounted on the door or window and are not visible from the front of the closed door or window , while only partially visible (part of the structure fixed to the fixed frame) with the door or window open. [0003] According to the invention, a hinge of this type is applied on a door or window comprising a fixed frame and a movable sash formed by parts made of metal, PVC or PVC-wood, having a profile having at least A perimeter channel for securing the operation and opening / closing fittings of a door or window that exactly includes concealed hinges. Background technique [0004] These hinges are configured to open doors or windows using conventional swivel openings or tilt and turn openings. [0005] This type of hinge basically includes: [0006] - a first fixing body...

AI Technical Summary

Problems solved by technology

[0024] However, the adjusting units shown so far, in particular those acting on the first and second horizontal axes which are of particular interest in this description, have disadvantages

[0025] The application of these adjustment units on the second movable body leads to a complex structure consisting of several parts (not a single piece), resulting in a reduction in the stability of the parts, which over time reduces the functionality and Accuracy in corresponding regulation

[0026] Furthermore, in the case of doors or windows positioned at a low height above the treadable surface, it can be very difficult to operate an adjustment device configured in this way on the second body
