Abstract
Abstract A hinge for metal doors and windows envisages that each bushing (7,8) be formed of two separate elements (11, 12), engaged with each other by axial coupling means (14, 15) reversible when the bushing (7, 8) is not inside a relative axial hole (9), and free to turn relative to each other: the first element (11) forms a cylinder to contain a pin (6) the hollow for the pin being off centre with respect to a longitudinal axis (X) of the bushing (7, 8); the other element (12) forms a first collar larger in diameter than the corresponding axial hole (9) that contains the bushing (7, 8); adjusting means (13) are envisaged on the first element (11) to vary the position of the first element (11) relative to the second element (12) when an external force is applied to the hinge body (1, 2), properly installed and in use, to turn it between two or more stable positions defined by grooves (1s, 2s) made in the axial hole (9).

Total Claims: 10
Claim 1
Independent Claim
294 words
A hinge for metal security doors and windows of the type comprising at least two hinge sections (1, 2) attachable to a door or window and related frame by corresponding segments (3, 4) to seat screw means (5) and a hinge pin (6) to be inserted into corresponding axial through holes (9) in the said hinge sections (1, 2), lined with cylindrical centring bushings (7, 8) and extending along a longitudinal axis (X); the surfaces inside the holes (9) having a plurality of longitudinal grooves (ls, 2s) used to securely engage with the bushings (7, 8) which have corresponding teeth (10) on them, the said hinge being characterized in that each of the said bushings (7, 8) consists of two separate elements (11, 12) engaged with each other by axial coupling means (14, 15) reversible when the bushing (7, 8) is not inside its axial hole (9) in the hinge section (1, 2), the said elements (11, 12) being always free to turn relative to each other about the said longitudinal axis (X); one of the said elements (11) forming a cylinder to contain the pin (6), the hollow in the cylinder being off centre with respect to the said longitudinal axis (X) of the bushing (7,8), and the other element (12) forming a first collar larger in diameter than the corresponding axial hole (9) and equipped with the said teeth (10); means (13) being envisaged on the cylindrical element (11) for adjusting its position relative to the second element (12) and allowing it, when an external force is applied to the corresponding hinge section (1, 2), properly installed and in use, to rotate between two or more stable positions, depending on the number of grooves (ls, 2s) made in the axial hole (9).
Claim 2
Dependent Claim
134 words
The hinge according to claim 1, characterized in that the said reversible axial coupling means consist of an end portion (lla) of the cylinder (11) smaller in diameter than the rest of the same cylinder (11), the free end of the said portion (lla) having an enlarged tapered rim (14) and a cylindrical portion (15) at the top of the second element (12) and whose outside diameter is equal to the diameter of the cylinder (11) and inside which there is a rim-like feature (16) which, if pressed with sufficient force to overcome the tapered rim (14) of the cylinder (11), axially engages the first collar (12) with the cylinder (11) but leaves them free to rotate relative to each other when the said bushing (7, 8) is not inside the corresponding hole (9).
Claim 3
Dependent Claim
84 words
The hinge according to claim 2 characterized in that the cylindrical portion (15) has at least one pair of weakening slits (15i) on its surface designed to allow elastic deformation of and, accordingly, an increase in the radius of, the two curved features formed on the cylindrical portion (15) when the collar (12) engages with the cylinder (11) and capable of providing a secure axial fastening between the two said elements when the bushings (7, 8) are inserted into the corresponding axial holes (9).
Claim 4
Dependent Claim
107 words
The hinge according to claim 2 characterized in that the outside surface of the cylindrical portion (15) of the collar (12) envisages a plurality of the said teeth (10) used to securely engage the said second element (12) inside the axial hole (9); the free circular contact surface at the bottom of the collar (12) being divided into two rings (18, 19), differing in thickness, the outer ring (18), when in use, coming into contact with the corresponding ring of the other collar (12), and the inner ring (19), with the smaller diameter, coming into contact with a second collar 20 made on the hinge pin (6).
Claim 5
Dependent Claim
97 words
The hinge according to claim 1 characterized in that the adjusting means (13) consist of a reference tooth (21) which engages with a corresponding groove (ls, 2s) and which is arranged radially on the outer surface on the cylindrical end of the first element (11) opposite the end that joins the second element (12); on the said end there being also envisaged a second slot (24) for a tool (25) to enable the first element to be turned so as to radially move the tooth (21) from one groove (ls, 2s) to the next or previous groove.
Claim 6
Dependent Claim
66 words
The hinge according to claim 5 characterized in that the tooth (21) is made on a flexible curved feature (22) capable of bending in order to permit the radial movement of the said tooth (21); the said arch (22) being formed by a first slot (23) made on the end of the said cylinder (11) in such a way as to form part of its edge.
Claim 7
Dependent Claim
35 words
The hinge according to claim 1 characterized in that there are eight grooves (1s, 2s) in the said axial hole (9) and eight corresponding teeth (10) to engage with them on the second element (12).
Claim 8
