Description

FIELD OF THE INVENTION

The present invention concerns a hinge for doors or windows made using section bar elements, for example made of metal such as aluminum or iron, or plastic material, such as for example PVC, to hinge to each other a mobile element of the door or window, or a panel, with respect to a fixed structural element, like the frame of the door or window. The hinge according to the present invention is provided with adjustment means that allow, during use, to adjust the position of the mobile element with respect to the fixed structural element in three directions, perpendicular to each other.

BACKGROUND OF THE INVENTION

In the field of doors or windows made with section bars, for example made of metal, such as aluminum or steel, or plastic material, such as for example PVC, different types of hinges are known, normally consisting of two hinging units, one of which is configured to be attached to the fixed frame of the door or window, while the other is configured to be attached to the mobile element of the door or window. A pivoting member connects the two hinging units to each other, to articulate them with respect to each other along a single hinging axis.
It is known that in hinges for doors or windows made using section bar elements, at least the hinging unit to be associated with the mobile element of the door or window must be configured so that it can be located, in the closed position, in the narrow space between the mobile element and the corresponding fixed frame of the door or window.
From the German patent publication DE-B3-102010017628 , a hinge for doors or windows made using section bar elements is known, in which three adjustments are possible of the two hinging units along three axes perpendicular to each other, substantially as provided in the preamble to claim 1.
From the present Applicant's European patent application EP-A-2735679 , a hinge is known that provides the possibility of adjusting the reciprocal position of the two hinging units along three axes perpendicular to each other, even if this known hinge cannot be used for doors or windows made with section bar elements.
One purpose of the present invention is to obtain a hinge for doors or windows made using section bar elements which is simple, efficient and inexpensive, and which at the same time allows easy and rapid assembly of the elements of the door or window on which it is installed.
Another purpose of the present invention is to obtain a hinge for doors or windows made using section bar elements which is also provided with adjustment means that allow to selectively adjust, during use, the position of the mobile element with respect to the corresponding fixed structural element in three directions, each perpendicular with respect to the other two, and so that each adjustment can be carried out simply, continuously and rapidly, without needing to dis-assemble either the mobile element from the fixed structural element or the different components of the hinge.
The Applicant has devised, tested and embodied the present invention to overcome the shortcomings of the state of the art and to obtain these and other purposes and advantages.

DETAILED DESCRIPTION OF ONE EMBODIMENT OF THE PRESENT INVENTION

With reference to fig. 1, a hinge 10 according to the present invention is shown installed on a door or window 11 to hinge a mobile element 12, which can be for example a door, a window or a panel, made with section bar elements 13, with respect to a fixed structural element 14, which can be for example the frame of the door or window 11 made with section bar elements 15. The section bar elements 13 and 15 can be made of aluminum for example, or other metal, or plastic material, such as PVC for example.
The hinge 10 comprises two hinging units 16 and 17, disposed coaxial to each other along a pivoting axis X, for example vertical, and a pivoting member 18 (fig. 4) configured to articulate the two hinging units 16 and 17 with respect to each other, as will be described hereafter in detail.
In particular, the first hinging unit 16 comprises a support element 19, substantially C-shaped and provided with a lower protuberance 20, an upper protuberance 21 and a central niche 22.
The lower protuberance 20 is provided with a cylindrical cavity 23, coaxial to the pivoting axis X, while the upper protuberance 21 is provided with a cavity 24 parallel to the pivoting axis X and slightly distant from it. In the cavity 24 a guide appendix 25 of a closing element 26 is suitable to be inserted slidingly, the closing element being provided with a cylindrical axial cavity 27 which, during use, is coaxial to the pivoting axis X.
The second hinging unit 17 comprises a pivoting element 28 having a first part 29, substantially cylindrical in shape, and a second part 30, substantially shaped like a parallelepiped. The first part 29 of the pivoting element 28 is provided with a through axial hole 31 and is configured to be disposed, during use, in the central niche 22 of the first hinging unit 16, coaxial to the pivoting axis X.
The second part 30 of the pivoting element 28 is provided with two first grooves 32 disposed in a first direction Y perpendicular to the pivoting axis X and in which two corresponding first blocks 33 of a connection element 34 are slidingly inserted, the connection element 34 being disposed between the second part 30 of the pivoting element 28 and a plate 35 which, during use, is attached to the mobile element 12 of the door or window 11.
The connection element 34, to be able to be disposed adequately between the fixed structural element 14 and the mobile element 12, especially when the latter is in the closed position, consists of a metal plate, with a thickness comprised for example between about 1 mm and about 6 mm, and is substantially L-shaped.
In particular, the connection element 34 comprises a first part 36 facing the external surface of the second part 30 of the pivoting element 28 and provided with the two first blocks 33.
A first eccentric element 37, of a known type, is interposed between the first part 36 of the connection element 34 and the second part 30 of the pivoting element 28, and is partly housed in a through hole 38 of the first part 36 of the connection element 34. The selective rotation of the first eccentric element 37 causes the displacement of the connection element 34 and of the mobile element 12 associated with it, in a first direction Y.
Two first clamping screws 39 inserted in two corresponding eyelets 40 of the first part 36 of the connection element 34 are suitable to clamp the latter in the desired position.
Furthermore, the connection element 34 comprises a second part 41, perpendicular to the first part 36 and parallel to the plate 35. The second part 41 comprises a central groove 42, parallel to the pivoting axis X and in which an intermediate element 43 is slidingly disposed, interposed between the second part 41 and the plate 35.
The intermediate element 43 is provided with two second blocks 44, disposed in a second direction Z, perpendicular both to the pivoting axis X and also to the first direction Y, and sliding in two corresponding pairs of second grooves 45 made in the second part 41 of the connection element 34.
A second eccentric element 46, of a known type, is interposed between the second part 41 of the connection element 34 and the intermediate element 43, and is partly housed in a through hole 47 of the second part 41 of the connection element 34. The selective rotation of the second eccentric element 46 causes the displacement of the intermediate element 43 and of the mobile element 12 associated with it, in the second direction Z.
Two second clamping screws 48 inserted in two corresponding eyelets 49 of the second part 41 of the connection element 34 are suitable to clamp the intermediate element 43 with respect to the connection element 34 in the desired position.
Third clamping screws 50 are suitable to clamp the intermediate element 43 on the plate 35 and fourth clamping screws 51 are suitable to clamp the intermediate element 43 and the plate 35 on the mobile element 12 of the door or window 11.
The pivoting member 18 comprises a first cylindrical bushing 52 inserted in the cylindrical cavity 23 of the lower protuberance 20 and having a cylindrical seating 53 coaxial to the pivoting axis X, and an upper collar 54, which has an external diameter a little less than the internal diameter of the cylindrical cavity 23 and on which the lower part of the pivoting element 28 of the second hinging unit 17 rests. The first cylindrical bushing 52 is axially mobile, together with the pivoting element 28, by means of a lower threaded grub screw 55.
The pivoting member 18 also comprises a pin 56 having its lower part inserted into the cylindrical seating 53 of the first cylindrical bushing 52, the central part inserted into the through axial hole 31 of the block 28 and the upper part inserted in a second cylindrical bushing 57 which in turn is inserted in the cylindrical axial cavity 27 of the closing element 26. Inside the cylindrical axial cavity 27 an elastic element 58 is disposed, which in the example supplied here is a helical spring, which constantly thrusts downward the second cylindrical bushing 57, the pin 56 and the first cylindrical bushing 52.
When the pivoting member 18 is assembled, a fifth clamping screw 59 is suitable to keep the closing element 26 clamped in the corresponding cavity 24 of the upper protuberance 21, so that the pin 56 is coaxial to the pivoting axis X and so that the second hinging unit 17 and the mobile element 12 associated with it can rotate freely with respect to the first hinging unit 16 and the fixed structural element 14 to which the latter is attached.
The adjustment of the hinge 10 and hence of the mobile element 12 with respect to the fixed structural element 14 of the door or window 11 is obtained as follows, simply and functionally, without needing to dis-assemble the mobile element 12 from the fixed structural element 14.
A first adjustment along the pivoting axis X, which in the example shown here is vertical, is obtained simply by selectively screwing or unscrewing the lower threaded grub screw 55. In fact, screwing this displaces upward the pivoting member 18 and the associated second hinging unit 17, and also the mobile element 12, with respect to the first hinging unit 16 and the fixed structural element 14.
A second adjustment in the first direction Y (figs. 4, 6 and 7), which in the example shown here is horizontal, is obtained by loosening the two first clamping screws 39, by rotating the first eccentric element 37 clockwise or anti-clockwise, which causes the lateral displacement to the right or to the left of the connection element 34 with respect to the pivoting element 28, and the new clamping in the desired position, by screwing the first clamping screws 39.
A third adjustment in the second direction Z (figs. 4, 8 and 9), which in the example shown here is also horizontal, but perpendicular to the first direction Y, is obtained by loosening the two second clamping screws 48, by rotating the second eccentric element 46 clockwise or anti-clockwise, which causes the lateral displacement to the right or to the left of the intermediate element 43 and the plate 35, and also of the mobile element 12 with respect to the connection element 34, and the new clamping in the desired position, by screwing the second clamping screws 48.
It is clear that each of the three adjustments described above can be carried out alone, in a pair or with any of the other two and/or in any order, depending on needs.
From the above description it is therefore clear that the hinge 10 comprises first adjustment means, consisting of the lower threaded grub screw 55, able to adjust the position of the second hinging unit 17 and the mobile element 12 in the direction of the pivoting axis X, second adjustment means consisting of the first eccentric element 37, able to adjust the position of the mobile element 12 in the first direction Y, perpendicular to the pivoting axis X, and third adjustment means consisting of the second eccentric element 46, able to adjust the position of the mobile element 12 in the second direction Z, perpendicular both to the pivoting axis X and also to the first direction Y.
It is also clear that modifications and/or additions of parts may be made to the hinge 10 as described heretofore, without departing from the field and scope of the present invention.
It is also clear that, although the present invention has been described with reference to some specific examples, a person of skill in the art shall certainly be able to achieve many other equivalent forms of hinge, having the characteristics as set forth in the claims and hence all coming within the field of protection defined thereby.
