Definitions
- the present invention concerns a friction hinge for a pivoting door, window or shutter and a method for mounting said pivoting door, window or shutter.
- the friction hinge concerned is intended to be advantageously used in the door, window or shutter industry to allow pivoting wings to move about a horizontal axis or a vertical axis, with respect to a frame mounted in a fixed manner on walls of buildings of any kind.
- the aforementioned pivoting wings are increasingly used for architectural reasons when making windows, skylights, or portholes.
- pivoting doors, windows or shutters can rotate about a horizontal rotation axis, generally placed half-way up the door, window or shutter, or about a vertical rotation axis that can be centred or even decentred, as there is no need for balancing like in the case of horizontal pivoting.
- the accessory that allows the pivoting leaf to pivot is commonly known in the field by the term “pivot hinge” or “friction hinge”, and hereafter the latter term will be used.
- a friction hinge is usually obtained through two distinct bodies, one intended to be fixed to the leaf, and the other to be fixed to the frame of the pivoting door, window or shutter.
- the two friction bodies are pivotably coupled together, in angularly adjustable position, through a mutual holding relationship by friction with respect to the relative rotation motion.
- the friction force that holds the pivoting door, window or shutter in position is of adjustable intensity and for this purpose an adjustment screw is usually foreseen that keeps the two friction bodies under compression with the desired force.
- friction hinge for example used for pivoting doors, windows or shutters using section bars of the line with the trade name "R", which foresees being fixed preferably in the middle of the frame through plates (or base blocks) inserted in recesses of the leaf and of the frame and fixed there in contrast against a projecting tooth of the recess, through dowels preferably of the grub screw type.
- R the trade name
- the dowel engages to the door, window or shutter through an irreversible deformation of the metal section bar of the door, window or shutter itself, consisting of an extruded piece of aluminium.
- the engagement of the dowel is indeed obtained through the formation of a cavity on the metal section bar, which is shaped by the penetration of the end of the dowel in the section bar.
- the main drawback of the known friction hinge described above is the difficulty that the fitter has in mounting the door, window or shutter and fixing such a hinge to the leaf and to the frame in the correct position. Indeed, if the plates are not placed with precision in the recess of the section bar, for example usually at the middle thereof, the dowels produce a milling impression on the metal section bar of the frame in a position that is then difficult to change.
- the fitter must therefore take special care in positioning the plates since if they are not fixed with the dowels exactly in the correct final position suitable for ensuring the perfect closure of the pivoting door, window or shutter, it is then difficult to move the dowels, i.e. to carry out a fine adjustment of the position of the plates along the longitudinal direction of the anchoring cavity, since clearly the dowel will tend to move and go back inside the cavity that has already formed on the section bar.
- the friction hinge described above does nevertheless have the advantage of being able to mount the leaf of the pivot, with the friction body already fixed, by inserting it frontally inside the frame.
- the two bodies of the friction hinge are equipped with a shaped foot to insert directly into the anchoring cavity of the section bar of the door, window or shutter without the use of intermediate plates.
- the need to fix the feet directly into the recess of the section bar of the door, window or shutter prevents the possibility of frontal installation of the leaf on the frame.
- friction hinge once the friction hinge is secured on a first frame of the door, window or shutter with its foot fixed through self-tapping screws to the relative recess of the first frame, it is no longer possible to frontally mount the leaf on the frame by interference of the hinge itself and it is thus necessary to leave the second frame without one side in order to be able to slot the hinge already fixed to the first frame into the anchoring cavity of the second frame.
- the correct fastening position of the feet of the two bodies is theoretically defined through measurement. Once such a position has been defined, the two bodies of the hinge are definitively fixed to the relative section bars through self-tapping screws. If the position of the hinge is not perfectly correct, it is necessary to replace the section bar that has been involved in the fastening of the hinge with the screws with another new one, given that it is impossible to make a new hole a few millimetres or tenths of millimetres from the previous hole.
- the friction hinges of the type described above therefore have the main drawback of not allowing adjustments of their position to be carried out along the anchoring cavity of the frames.
- the different section bars have anchoring recesses of different dimensions with holding teeth that vary their shape and their projection above the recess. Consequently, the hinges must currently be optimised for the specific section bar on which they must then be mounted. Therefore, manufacturers of friction hinges for pivots as well as the fitters that work with different doors, windows and shutters must hold in stock a large number of hinges, each susceptible of being mounted on a specific corresponding section bar of a door, window or shutter. This circumstance means an increase in production and installation costs, which, in the end, result in a higher cost of the pivoting door, window or shutter.
- a friction hinge for a pivoting window comprising a fixed frame provided with a first section bar having a first anchoring cavity and a movable leaf, provided with a second section bar having a second anchoring cavity.
- the friction hinge comprises a first friction body susceptible of being held on the fixed frame through first fastening means mechanically engaged to the first anchoring cavity of the first section bar and rigidly fastened to the first friction body.
- the friction hinge further comprises a second friction body pivotably mechanically coupled to the first friction body and susceptible of being fastened to the movable leaf through second fastening means mechanically engaged to the second anchoring cavity of the second section bar and rigidly fastened to the second friction body.
- the basic purpose of the present invention is therefore to avoid the drawbacks encountered in the known solutions quoted above, providing a friction hinge for a pivoting door, window or shutter, which can be installed in section bars of doors, windows or shutters having different dimensional characteristics and in particular anchoring recesses of different dimensions.
- Another purpose of the present finding is to provide a friction hinge for a pivoting door, window or shutter, which permits adjustment of its position after having been mounted on the section bars of the door, window or shutter.
- a further purpose of the present finding is to provide a friction hinge for a pivoting door, window or shutter, which allows adjustment of the position of the leaf with respect to the fixed frame in a totally safe and extremely precise manner.
- Another purpose of the present finding is to provide a friction hinge for a pivoting door, window or shutter, which permits its adjustment even with the door, window or shutter installed and in particular after the glass pane has been mounted.
- Another purpose of the present finding is to provide a friction hinge for a pivoting door, window or shutter, which allows pivoting doors, windows or shutters of substantial weight to be supported.
- Another purpose of the present finding is to provide a friction hinge for a pivoting door, window or shutter, which is constructively simple and operatively totally reliable.
- Another purpose of the present finding is to provide a friction hinge for a pivoting door, window or shutter, which allows the storage costs to be reduced.
- a further purpose of the present finding is to provide a method for mounting a pivoting door, window or shutter, which allows the costs linked to its production process and to its maintenance to be reduced.
- a further purpose of the present finding is to provide a method for mounting a pivoting door, window or shutter, which allows the movable leaf to be applied frontally in the fixed frame.
- a further purpose of the present finding is to provide a method for mounting a pivoting door, window or shutter, which allows the position of the leaf to be adjusted with respect to the frame in a precise manner.
- a further purpose of the present finding is to provide a method for mounting a pivoting door, window or shutter, which allows the position of the leaf to be adjusted with respect to the frame after having installed the glass pane.
- a further purpose of the present finding is to provide a method for mounting a pivoting door, window or shutter, which allows the hinge to be installed on doors, windows or shutters having different dimensional characteristics and in particular anchoring recesses of different dimensions.
- the friction hinge 1 is intended to be used in a per sé conventional manner together with a second analogous friction hinge, to adjust the position of a movable leaf 3 on a fixed frame 2, with the movable leaf 3 being able to rotate between different positions about a rotation axis Y, horizontal or vertical, according to the different application requirements, and being able to be advantageously used usually to obtain a pivoting door, window or shutter such as a window, a skylight or a porthole.
- the friction hinge 1 concerned is in particular intended for doors, windows or shutters consisting of metal section bars, generally made from aluminium, usually able to be obtained with extrusion processes.
- the fixed frame 2 is mounted on the masonry wall of a building forming the support framework of the movable leaf 3 and it is arranged perimetrically delimiting the space used by the door, window or shutter.
- the fixed frame 2 is obtained with at least a first section bar 2' having an inner side 4 (i.e. facing towards the space used by the door, window or shutter) with a first anchoring cavity 5 formed, delimited by at least a first longitudinal tooth 6a for partially closing the opening exposed on the aforementioned inner side 4.
- the movable leaf 3 is provided with at least a second section bar 3' having an outer side 7, i.e. facing towards the outside of the door, window or shutter, in a position substantially facing the first anchoring cavity 5, and with a second anchoring cavity 8 formed, delimited by at least a second longitudinal tooth 9, for partially closing the opening exposed on the aforementioned outer side 7.
- the fixed frame 2 and the movable leaf 3 are also each provided, in a per sé totally conventional way, and for half of their perimeter extension, with at least an inversion section bar, respectively indicated with reference numerals 2" for the fixed frame 2 and with reference numeral 3" for the movable leaf 3, intended to go into abutment with the interposition of a gasket, respectively against the corresponding second section bar 3' of the leaf 3 and against the first section bar 2' of the frame2 to determine the sealed closing of the leaf 2 on the frame 3.
- Each of the two friction hinges 1 of the pivoting door, window or shutter comprises a first friction body10, and a second friction body 11 pivotably mechanically coupled together in friction relationship and pressed against one another for example through a connection screw 130, adjustable in a per sé known way, to vary the friction force between the two friction bodies 10 and 11.
- the first friction body 10 is susceptible of being held on the fixed frame 2 through first fastening means, generically indicated with reference numeral 13, which are mechanically engaged to the first anchoring cavity 5 of the first section bar 2' of the fixed frame 2 and are rigidly fixed to the first friction body 10.
- first fastening means generically indicated with reference numeral 13
- second fastening means generically indicated with reference numeral 14 which are mechanically engaged to the second anchoring cavity 8 of the second section bar 3' of the movable leaf 3 and are rigidly fixed to the second friction body 11.
- At least one of the first and second fastening means 13, 14, and advantageously both of the fastening means 13, 14, comprises a plate 15, which is fixed to the respective inner or outer side of the corresponding first or second section bar 2', 3', and a counterplate 16, which is provided with an engagement portion 16' constrained by interference in the first or second recess 5, 8 of the corresponding first or second section bar2', 3' beneath the plate 15.
- the aforementioned counterplate 16 is fixed to the corresponding first or second friction body10, 11 through at least a first screw 17, and advantageously through two screws 17, having the head 17' constrained to the relative friction body 10, 11, and the shaft 17" arranged to cross the through holes 22 formed on the two friction bodies 10, 11 and aligned with a first opening 18 formed in the plate 15 to manage to engage with the end in a first threaded hole 19 of the counterplate 16.
- the screws 17 develop perpendicularly to the inner and outer sides 4, 7 respectively of the first and second section bar 2', 3', perpendicular to the prevalent development of the plate 15 and of the counterplate 16, and they have the shafts 17" that insert in the through holes 22 that are formed in two wings 100 of the two friction bodies 10, 11.
- the aforementioned wings 100 extend in a stepped fashion from a resting wall 10', 11' of the same friction bodies 10, 11 as explained hereafter.
- the fastening means 13, 14 of the two friction bodies 10, 11 are the same and therefore hereafter their components will be indicated indifferently and generically, i.e. without distinction through the adjectives first and second.
- the longitudinal tooth 6, 9 of the anchoring cavity 5, 8 of the section bar 2', 3' extends partially closing the recess 5, 8 and it is interposed between the counterplate 16 inserted in the recess 5, 8 and the resting wall 10', 11' of the relative friction body 10, 11 placed in contact with an outer front face 20 of the section bar 2', 3' (opposite the inner face of which from which the aforementioned longitudinal tooth 6, 9 extends).
- the counterplate 16 rigidly fixes to the relative friction body 10, 11 with the section bar 2', 3' of the frame 2 and of the leaf 3 interposed.
- the engagement portion 16' of the counterplate 16 is equipped with a tilted wall 16", which when the first screws 17 are clamped, is compressed against the longitudinal tooth 6, 9 of the anchoring cavity 5, 8 of the relative section bar 2', 3' so that the aforementioned tilted wall 16" slidably skids on the longitudinal tooth 6, 9 pulling the relative friction body 10, 11 with it until it is taken with its resting wall 10', 11' in abutment against the outer front face 20 of the section bar 2', 3' of the frame 2 or of the leaf 3 and with it clamping together the section bar 2', 3' itself, the friction body 10, 11, the plate 15 and the counterplate 16.
- each friction body 10, 11 is a metallic body shaped for example by extrusion and has the resting wall 10', 11', placed in abutment against the outer front wall 20 of the relative section bar 2', 3' on which it is mounted, and two wings 100, which extend perpendicularly from the resting wall 10', 11' above the anchoring cavity 5, 8 going to rest with a side face thereof 21 above the plate 15 keeping the through hole 22 aligned with the first opening 18 formed on the same plate 15 to allow the insertion of the first screws 17.
- the plate 15 defines a seat 24 for containing the counterplate16 through two opposite pairs of walls, two of which are side walls 25 and two are end walls 26.
- the plate 15 is made from metallic material, preferably steel, and it has an elongated shape in the direction of the anchoring cavity 5, 8 with the pair of side walls 25 obtained with two bends that at the ends define a resting edge 27 preferably in abutment on the inner side 4 or outer side 7 of the profile 2', 3' in particular above the two teeth 9, 9' that delimit the opening of the anchoring cavity 5, 8.
- the anchoring cavity 5, 8 has, in addition to the longitudinal tooth 9 for interference with the engagement portion 16' of the counterplate 16, also a second longitudinal tooth 9' opposite the longitudinal tooth 9 with respect to the opening of the recess 5, 8.
- the two end walls 26 each have a second bend that delimits a fastening fin 28, parallel to the central portion of the plate 15, and intended to be fixed through second screws 29 onto the section bar 2', 3' at the anchoring cavity 5, 8 and advantageously on the bottom of the aforementioned recess.
- the counterplate16 is provided with a first portion 30, which is inserted, in particular without clearance, in the containment seat 24 defined by the plate 15, and with a second portion 31 inserted with clearance in the anchoring cavity 5, 8.
- a projecting rib 33 is formed on which the inner face of the plate 15 rests.
- the friction hinge 1 also comprises an eccentric element 34, which is provided with an enlarged head 35 inserted in a second shaped opening36 formed on the plate 15 and with a shaft 37 fixed eccentrically to the head 35, and pivotably engaged in a second hole 38 formed in the counterplate 16, for this purpose being for example upset at the free end beyond the counterplate 16.
- the first openings 18 are shaped like elongated slots in the direction parallel to the direction of development of the anchoring cavity 5, 8
- the second opening 36 is shaped like an elongated slot in the direction transversal to the direction of development of the anchoring cavity 5, 8.
- the enlarged head 35 of the eccentric element 34 is inserted without clearance into the second opening 36 in a direction longitudinally parallel to the anchoring cavity 5, 8 and it can slide in the second opening 36 in a direction transversal to the same anchoring cavity 5, 8.
- An object of the present invention is also a method for mounting a pivoting door, window or shutter advantageously provided with a friction hinge 1 of the type described above.
- the method for mounting a pivoting door, window or shutter comprising a first step of fastening one of the two friction bodies 10, 11 to the respective section bar 2', 3' of fixed frame 2 or of the movable leaf 3.
- a first fastening step foresees a step of inserting the counterplate 16 inside the anchoring cavity 5, 8 of the section bar 2', 3' with the engagement portion 16' placed beneath the longitudinal tooth 6, 9; a step of mounting the counterplate 16 above the plate 15 and the friction body 10, 11 with its side face 21 resting above the plate 15.
- the counterplate 16 inserts with its first portion 30 without clearance in the containment seat 24 defined by the plate 15 and with its second portion 31 with clearance in the anchoring cavity 5, 8.

Description
- The present invention concerns a friction hinge for a pivoting door, window or shutter and a method for mounting said pivoting door, window or shutter.
- More specifically, the friction hinge concerned is intended to be advantageously used in the door, window or shutter industry to allow pivoting wings to move about a horizontal axis or a vertical axis, with respect to a frame mounted in a fixed manner on walls of buildings of any kind. The aforementioned pivoting wings are increasingly used for architectural reasons when making windows, skylights, or portholes.
- As known, pivoting doors, windows or shutters can rotate about a horizontal rotation axis, generally placed half-way up the door, window or shutter, or about a vertical rotation axis that can be centred or even decentred, as there is no need for balancing like in the case of horizontal pivoting.
- In the case of horizontal pivoting, usually when opening the lower part of the leaf projects outwards and the upper part projects inwards. For the pivoting door, window or shutter the hinges must be equipped with frictions to prevent the uncontrolled rotation of the leaf and allow opening to be regulated.
- The accessory that allows the pivoting leaf to pivot is commonly known in the field by the term "pivot hinge" or "friction hinge", and hereafter the latter term will be used. Such a friction hinge is usually obtained through two distinct bodies, one intended to be fixed to the leaf, and the other to be fixed to the frame of the pivoting door, window or shutter. The two friction bodies are pivotably coupled together, in angularly adjustable position, through a mutual holding relationship by friction with respect to the relative rotation motion. The friction force that holds the pivoting door, window or shutter in position is of adjustable intensity and for this purpose an adjustment screw is usually foreseen that keeps the two friction bodies under compression with the desired force.
- On the market there is a friction hinge, for example used for pivoting doors, windows or shutters using section bars of the line with the trade name "R", which foresees being fixed preferably in the middle of the frame through plates (or base blocks) inserted in recesses of the leaf and of the frame and fixed there in contrast against a projecting tooth of the recess, through dowels preferably of the grub screw type. The two friction bodies of the hinge are then fixed onto the plates through screws.
- The dowel engages to the door, window or shutter through an irreversible deformation of the metal section bar of the door, window or shutter itself, consisting of an extruded piece of aluminium. The engagement of the dowel is indeed obtained through the formation of a cavity on the metal section bar, which is shaped by the penetration of the end of the dowel in the section bar.
- The main drawback of the known friction hinge described above is the difficulty that the fitter has in mounting the door, window or shutter and fixing such a hinge to the leaf and to the frame in the correct position. Indeed, if the plates are not placed with precision in the recess of the section bar, for example usually at the middle thereof, the dowels produce a milling impression on the metal section bar of the frame in a position that is then difficult to change.
- The fitter must therefore take special care in positioning the plates since if they are not fixed with the dowels exactly in the correct final position suitable for ensuring the perfect closure of the pivoting door, window or shutter, it is then difficult to move the dowels, i.e. to carry out a fine adjustment of the position of the plates along the longitudinal direction of the anchoring cavity, since clearly the dowel will tend to move and go back inside the cavity that has already formed on the section bar.
- The friction hinge described above does nevertheless have the advantage of being able to mount the leaf of the pivot, with the friction body already fixed, by inserting it frontally inside the frame.
- In accordance with a different embodiment, the two bodies of the friction hinge are equipped with a shaped foot to insert directly into the anchoring cavity of the section bar of the door, window or shutter without the use of intermediate plates. The need to fix the feet directly into the recess of the section bar of the door, window or shutter prevents the possibility of frontal installation of the leaf on the frame. Indeed, in accordance with this embodiment of friction hinge, once the friction hinge is secured on a first frame of the door, window or shutter with its foot fixed through self-tapping screws to the relative recess of the first frame, it is no longer possible to frontally mount the leaf on the frame by interference of the hinge itself and it is thus necessary to leave the second frame without one side in order to be able to slot the hinge already fixed to the first frame into the anchoring cavity of the second frame.
- The correct fastening position of the feet of the two bodies is theoretically defined through measurement. Once such a position has been defined, the two bodies of the hinge are definitively fixed to the relative section bars through self-tapping screws. If the position of the hinge is not perfectly correct, it is necessary to replace the section bar that has been involved in the fastening of the hinge with the screws with another new one, given that it is impossible to make a new hole a few millimetres or tenths of millimetres from the previous hole.
- In the field of pivoting doors, windows or shutters the problems connected with the mounting of the hinges on the profiles of the doors, windows or shutters have particular importance.
- A particular requirement in the installation of pivoting doors, windows or shutters is the need to modify the position of the hinges, once they have been mounted, in order to allow the necessary adjustment operations to be carried out.
- Indeed, it must furthermore be considered that when the pivoting door, window or shutter is mounted, the glass pane has not yet been installed. The latter, once mounted, substantially increases the weight of the pivoting leaf and closes up all the clearances of the support kinematism of the leaf on the frame with the consequence that inevitably the position of the leaf falls at least slightly. If the fitter has not predicted this yielding he must try to move the leaf with difficult adjustments or with the replacement of the section bars.
- The friction hinges of the type described above therefore have the main drawback of not allowing adjustments of their position to be carried out along the anchoring cavity of the frames.
- The process for mounting such friction hinges is consequently very complex and requires particularly specialised workers in order to allow the leaf of the pivot to be mounted in an optimal manner and with perfect seal on the frame.
- On the market there are numerous section bars of pivoting doors, windows or shutters, the dimensions of which can vary slightly, for example depending on the manufacturer, even in the case in which they refer to standardised models like in the case of well-known European chamber section bars.
- In particular, the different section bars have anchoring recesses of different dimensions with holding teeth that vary their shape and their projection above the recess. Consequently, the hinges must currently be optimised for the specific section bar on which they must then be mounted. Therefore, manufacturers of friction hinges for pivots as well as the fitters that work with different doors, windows and shutters must hold in stock a large number of hinges, each susceptible of being mounted on a specific corresponding section bar of a door, window or shutter. This circumstance means an increase in production and installation costs, which, in the end, result in a higher cost of the pivoting door, window or shutter.
- For instance from
document FR 2 372 948 claim 1, it is known a friction hinge for a pivoting window comprising a fixed frame provided with a first section bar having a first anchoring cavity and a movable leaf, provided with a second section bar having a second anchoring cavity.

first screws 17 by screwing, thecounterplate 16 rigidly fixes to therelative friction body frame 2 and of theleaf 3 interposed. - For this purpose, and in accordance with a preferred characteristic of the present invention, the engagement portion 16' of the
counterplate 16 is equipped with a tiltedwall 16", which when thefirst screws 17 are clamped, is compressed against thelongitudinal tooth 6, 9 of theanchoring cavity 5, 8 of the relative section bar 2', 3' so that the aforementioned tiltedwall 16" slidably skids on thelongitudinal tooth 6, 9 pulling therelative friction body front face 20 of the section bar 2', 3' of theframe 2 or of theleaf 3 and with it clamping together the section bar 2', 3' itself, thefriction body plate 15 and thecounterplate 16. - More clearly, in accordance with the preferred embodiment illustrated in the attached figures, each
friction body front wall 20 of the relative section bar 2', 3' on which it is mounted, and twowings 100, which extend perpendicularly from the resting wall 10', 11' above the anchoringcavity 5, 8 going to rest with a side face thereof 21 above theplate 15 keeping the throughhole 22 aligned with thefirst opening 18 formed on thesame plate 15 to allow the insertion of the first screws 17. - Advantageously, the
plate 15 defines aseat 24 for containing the counterplate16 through two opposite pairs of walls, two of which areside walls 25 and two areend walls 26. - Preferably, the
plate 15 is made from metallic material, preferably steel, and it has an elongated shape in the direction of theanchoring cavity 5, 8 with the pair ofside walls 25 obtained with two bends that at the ends define a restingedge 27 preferably in abutment on the inner side 4 orouter side 7 of the profile 2', 3' in particular above the twoteeth 9, 9' that delimit the opening of theanchoring cavity 5, 8. - For this purpose, the anchoring
cavity 5, 8 has, in addition to thelongitudinal tooth 9 for interference with the engagement portion 16' of thecounterplate 16, also a second longitudinal tooth 9' opposite thelongitudinal tooth 9 with respect to the opening of therecess 5, 8. - The two
end walls 26 each have a second bend that delimits afastening fin 28, parallel to the central portion of theplate 15, and intended to be fixed throughsecond screws 29 onto the section bar 2', 3' at theanchoring cavity 5, 8 and advantageously on the bottom of the aforementioned recess. - Advantageously, the counterplate16 is provided with a
first portion 30, which is inserted, in particular without clearance, in thecontainment seat 24 defined by theplate 15, and with asecond portion 31 inserted with clearance in theanchoring cavity 5, 8. - In order to promote the sliding of the
counterplate 16 with respect to the profile 2', 3' by means of the interference between the tiltedwall 16" of thecounterplate 16 and thelongitudinal tooth 6, 9 of theanchoring cavity 5, 8, on theupper face 32 of thecounterplate 16, preferably on the opposite side to that where the tiltedwall 16" is foreseen, a projectingrib 33 is formed on which the inner face of theplate 15 rests. - In accordance with an advantageous characteristic of the present invention, the

In accordance with this advantageous embodiment, thefirst openings 18 are shaped like elongated slots in the direction parallel to the direction of development of theanchoring cavity 5, 8 whereas thesecond opening 36 is shaped like an elongated slot in the direction transversal to the direction of development of theanchoring cavity 5, 8. Theenlarged head 35 of theeccentric element 34 is inserted without clearance into thesecond opening 36 in a direction longitudinally parallel to theanchoring cavity 5, 8 and it can slide in thesecond opening 36 in a direction transversal to thesame anchoring cavity 5, 8. - Operatively, by rotating the
enlarged head 35 of theeccentric element 34 thehead 35 itself slides in the direction transversal to the development of theanchoring cavity 5, 8 whereas its shaft slides in the longitudinal direction to the development of theanchoring cavity 5, 8 determining the sliding of thecounterplate 16 to which the same shaft is engaged beneath theplate 15. Consequently, the movement of thecounterplate 16 determines the movement of thefriction body anchoring cavity 5, 8 therefore allowing their adjustment in such a direction. - An object of the present invention is also a method for mounting a pivoting door, window or shutter advantageously provided with a
friction hinge 1 of the type described above. - Hereafter, for the sake of simplicity of presentation we will refer to the same nomenclature used up to now, even though it should be understood that the present method can also be used with hinges not provided with all of the characteristics considered above.
- The method for mounting a pivoting door, window or shutter according to the present invention comprising a first step of fastening one of the two
friction bodies frame 2 or of themovable leaf 3. Such a first fastening step foresees a step of inserting thecounterplate 16 inside the anchoringcavity 5, 8 of the section bar 2', 3' with the engagement portion 16' placed beneath thelongitudinal tooth 6, 9; a step of mounting thecounterplate 16 above theplate 15 and thefriction body side face 21 resting above theplate 15. - In such a mounting step, the
counterplate 16 inserts with itsfirst portion 30 without clearance in thecontainment seat 24 defined by theplate 15 and with itssecond portion 31 with clearance in theanchoring cavity 5, 8. - Of course, the sequence of mounting steps of the three components one on top of the other can vary without for this reason departing from the scope of protection of the present patent document.
- Such a mounting step therefore can also be carried out using section bars 2', 3' having
anchoring recesses 5, 8 provided with different transversal width, keeping the clearance with which thesecond portion 31 of thecounterplate 16 is inserted in theanchoring cavity 5, 8. - The first fastening step thus foresees a preliminary locking step of the
friction body first screw 17 into the first threadedhole 19 of thecounterplate 16. - Such screwing determines the compression of the engagement portion 16' of the
counterplate 16 in abutment against thelongitudinal tooth 6, 9 of theanchoring cavity 5, 8 of the section bar 2', 3' and the compression of thefriction body counterplate 16 slides transversally to the longitudinal development direction of the anchoring cavity5, 8 with its tiltedwall 16" that slides on thelongitudinal tooth 6, 9 of theanchoring cavity 5, 8 of the section bar 2', 3' and until the resting wall 10', 11' of the corresponding friction body10, 11 comes into abutment against the outerfront face 20 of the section bar 2', 3'. - Therefore, given that the
friction body anchoring cavity 5, 8 until it meets the same section bar 2', 3', the method according to the invention makes it possible to mount the pivoting door, window or shutter through theaforementioned friction hinge 1, even in the presence of section bars 2', 3' having dimensions of theanchoring cavity 5, 8 and of itslongitudinal tooth 6, 9 that are even substantially different. - The first fastening step thus foresees a final locking step of the
friction body plate 15 to the same section bar 2', 3' through the use of at least a second screw 29 (and preferably two second screws 29). - Once the first fastening step is finished there is then a step of frontal insertion of the
movable leaf 3 into the fixedframe 2 followed by a second step of fastening the other of thefriction bodies frame 2 or of themovable leaf 3. Such a second fastening step can be operatively the same, mutatis mutandis, as the aforementioned first fastening step. - The method for mounting the pivoting door, window or shutter object of the present invention also preferably comprises a step of adjusting the longitudinal position of the
friction hinge 1. Such an adjustment step comprises, for this purpose, a step of loosening thefirst screw 17 in order to allow the relative sliding of thefriction body plate 15; a subsequent step of setting theeccentric element 34 in rotation, determining the sliding of the counterplate16 beneath theplate 15 and thus the movement of therelative friction body anchoring cavity 5, 8 until a predetermined optimal closing position of theleaf 3 on theframe 2 is reached. During the sliding of thecounterplate 16 beneath theplate 15, thefirst screw 17 slides in thefirst opening 18 shaped like an elongated slot formed in theplate 15 parallel to theanchoring cavity 5, 8. - With the subsequent step of clamping the
first screw 17, thefriction body - The finding thus conceived therefore achieves the predetermined purposes.
- Of course, in its practical embodiment, it can also take on different shapes and configurations from the one illustrated above without for this reason departing from the present scope of protection. Moreover, all of the details can be replaced with technically equivalent elements and the shapes, sizes and materials used can be whatever according to the requirements.
