Definitions

• the present invention relates to a hinge for windows/doors/shutters, according to the preamble of independent claim no. 1.
• the hinge in question is advantageously intended to be used to rotatably connect together a wing of a window/door/shutter and a fixed frame of the same window/door/shutter, wherein the wing can for example be that of a door, a window, a French window or a wardrobe.
• the hinge which is the subject of the present invention is advantageously but not exclusively of the type known in the technical jargon of the sector as “concealed” or even “invisible”, as it is not visible from the outside once the wing is placed in a closed position, since all the elements which form the hinge are substantially recessed inside the wing and the frame.
• the hinge in question therefore advantageously falls in the field of windows/doors/shutters, in the field of production and assembly of accessories for windows/doors/shutters and more in general in the field of interior design and the production of windows/doors/shutters and furniture.
• hinges usually consist of two hinge elements, one of which is intended to be fixed to a wing and the other to a fixed frame, and articulation means, which comprise for example one or more articulation arms to allow a rotation of the wing with respect to the frame, usually of approximately 180° around a hinge axis.
• a concealed (or invisible) type hinge in which the hinge elements are recessed inside corresponding housings created in the wing and in the frame so that only the articulation arms between the two elements of the hinge itself protrude outside the aforesaid housings.
• one of the two hinge elements in particular the one intended to be recessed in a respective housing of the fixed frame, is placed to allow an adjustment of the height of the wing itself with respect to the floor.
• such a hinge element is provided with an external hull, intended to be fixed in the respective housing, and with an adjustment body, slidably associated with the external hull along a vertical direction, mechanically connected to the articulation arms and provided with slotted holes, which are elongated along the vertical direction and crossed by fixing screws inserted in corresponding threaded holes made on the external hull.
• the main drawback is that the adjustment body is locked in position to the external hull only thanks to the friction force that develops between the adjustment body pressed by the heads of the fixing screws and the external hull.
• a further drawback is that, in the case of particularly heavy wings, it is necessary to employ more than one operator to install the window/door/shutter, at least one of whom must keep the wing at the desired height and one who must lock the adjustment body in position.
• hinges are known in the field, as for example emerges from prior art documents EP 3103948 , DE 202006004198 and CN 103061629 , which are provided with a hinge element with a vertical adjustment body to which the hinging means are connected.
• the hinge includes at least one movement mechanism provided with a wedge with a tilted surface placed to act against a corresponding tilted surface of the same adjustment body.
• the problem underlying the present invention is therefore that of overcoming the drawbacks manifested by the known solutions discussed above, by providing a hinge for windows/doors/shutters, which is suitable for windows/doors/shutters having particularly heavy wings, for example around 80 kg or more.
• a further object of the present invention is to provide a hinge for windows/doors/shutters which allows the height of the wing of the window/door/shutter to be easily adjusted, even when the aforesaid wing is particularly heavy.
• a further object of the present invention is to provide a hinge for windows/doors/shutters which allows the height of the wing of the window/door/shutter to be adjusted in an extremely precise manner, even when the aforesaid wing is particularly heavy.
• a further object of the present invention is to provide a hinge for windows/doors/shutters which is simple and economical to produce.
• a further object of the present invention is to provide a hinge for windows/doors/shutters which is operationally wholly reliable.
• the reference numeral 1 indicates a hinge for windows/doors/shutters which is the subject matter of the present invention.
• the hinge 1 in question is intended to movably connect together a wing and a frame of a window/door/shutter, so as to allow opening and closing an opening delimited at least partially by the aforesaid frame, wherein the wing can for example be that of a door, a window, a French window or a piece of furniture.
• the hinge 1 in question comprises a first hinge element 2, which is intended to be embedded in a respective containment housing made on the wing or on the frame, extended lengthwise along a main first extension axis X thereof and depthwise along a second extension axis Y thereof orthogonal to the aforesaid first extension axis X between a first internal side 3, extended substantially on a first lying plane ⁇ parallel to the first extension axis X, and a first external side 4, opposite the first internal side 3 and intended to be directed towards the bottom of the containment housing.
• the first hinge element 2 also extends widthwise along a third extension axis Z orthogonal to the main first extension axis X and to the second extension axis Y.
• a first hinge element 2 comprises at least one first external hull 5 and a first adjustment body 7.
• the first external hull 5 defines a first guide seat 6, which extends along the first extension axis X and opens on the first internal side 3, and is provided with at least one bottom wall 21, which is placed to delimit the first guide seat 6 in a position opposite the first internal side 3.
• first external side 4 of the first hinge element 2 is defined by the bottom wall 21.
• the first adjustment body 7 is also slidably inserted, at least along the first extension axis X, in the first guide seat 6 of the first external hull 5.
• the hinge 1 further comprises a second hinge element 8, which is intended to be embedded in a respective containment housing made on the other between the wing and the frame, and articulation means 9, which movably connect the first hinge element 2, at the first adjustment body 7, and the second hinge element 8 between a closed position and at least one open position.
• the first external hull 5 will be inserted in the corresponding containment housing made on the wing or on the frame with the first external side 4 thereof facing towards the bottom of the aforesaid containment housing and with the first extension axis X thereof oriented vertically, so that it is possible to adjust the height at which the wing is located with respect to the floor by translating the first adjustment body 7 along the main first extension axis X in the first guide seat 6 defined by the first external hull 5.
• the first hinge element 2 is intended to be embedded in a respective containment housing made on the frame and the second hinge element 8 is intended to be embedded in a respective containment housing made on the wing.
• the articulation means 9 are placed to guide the first and second hinge elements 2, 8 to move with respect to each other between the closed position and the at least one open position by means of a rotational motion (in the case where the hinge 1 in question is for example a traditional visible hinge), in particular around a rotation axis parallel to the main first extension axis X of the first hinge element 2, or by means of a compound roto-translation motion (in the case where the hinge 1 in question is for example an invisible hinge), in which in particular one of the first and second hinge elements 2, 8 moves with respect to the other by rotating around a rotation axis which is parallel to the main first extension axis X and which translates along a curved or circular trajectory on a plane orthogonal to the aforesaid main first extension axis X.
• a rotational motion in the case where the hinge 1 in question is for example a traditional visible hinge
• a compound roto-translation motion in the case where the hinge 1 in question is for example an invisible hinge
• the articulation means 9 comprise one or more articulation arms 34, which are mechanically connected at their end portions, by means of hinge pins parallel to the main first extension axis X, on one side to the first hinge element 2, in particular to the first adjustment body 7 of the latter, and on the other side to the second hinge element 8, in particular to a second adjustment body 41 of the latter which will be better described below, in at least a rotatable manner (and possibly also a sliding manner, with one or more of the hinge pins capable of translating along corresponding guides made on the first adjustment body 7 and/or on the second hinge element 8, in particular on the second adjustment body 41 of the second hinge element 8).
• Such articulation arms 34 can possibly be hinged together at the center (if more than one articulation arm 34 is provided and not just one). Thereby, the aforesaid articulation arms 34 are in particular placed to guide the first and second hinge elements 2, 8 to move with respect to each other between the closed position and the open position by means of a compound roto-translation motion.
• the articulation means 9 comprising the aforesaid articulation arms 34 are of the type with seven fulcrums.
• the articulation means 9 can be of any other type, for example with five fulcrums or of a type that combines fulcrums together with sliding components.
• the second hinge element 8 advantageously extends in length along a fourth main extension axis S thereof which is parallel to the main first extension axis X of the first hinge element 2 and in depth along a fifth extension axis T which is orthogonal to the aforesaid fourth extension axis S between a second internal side 35, extending substantially on a second lying plane ⁇ which is parallel to the fourth extension axis S, and a second external side, opposite the second internal side 35 and intended to be directed towards the bottom of the respective containment housing.
• the first and second hinge elements 2, 8 are placed with their first and second internal sides 3, 35 close together and facing each other and with the first and second lying planes ⁇ , ⁇ substantially parallel.
• first and second hinge elements 2, 8 are placed with the first and second internal sides 3, 35 distanced from each other.
• the articulation means 9 are placed to allow a 180° rotation between the first and second hinge body 2, 8 from the closed position to a maximum open position, so that in the aforesaid maximum open position the first and second hinge elements 2, 8 are placed next to each other with the first and second lying planes ⁇ , ⁇ substantially coplanar and with the first and second internal sides 3, 35 facing in the same direction.
• the first adjustment body 7 of the first hinge element 2 defines a first housing seat 37 and the second hinge element 8 defines a second housing seat 38, which first and second housing seats 37, 38 are preferably communicating with each other in the closed position, so that in the closed position the articulation means 9 (in particular the articulation arms 34 thereof) are contained in the aforesaid first and second housing seats 37, 38.
• the second hinge element 8 preferably comprises a second external hull 39, which defines a second guide seat 40 extending along said fifth extension axis T and opening on the second internal side 35, and a second adjustment body 41, which is slidably inserted, at least along the fifth extension axis T, in the second guide seat 40 of the second external hull 39. Furthermore, the second hinge element 8 preferably extends widthwise along a sixth extension axis U orthogonal to the fourth main extension axis S and to the fifth extension axis T.
• the articulation means 9 movably connect the first hinge element 2, at the first adjustment body 7, and the second hinge element 8, at the second adjustment body 41, between a closed position and at least one open position.
• the second hinge element 8 comprises adjustment means placed to precisely set the position of the second adjustment body 41 along the fifth extension axis T in the second guide seat 40 of the second external hull 39, which adjustment means will not be described in detail below as they are already generally known to those skilled in the art.
• the second housing seat 38 is obtained on the second adjustment body 41 of the second hinge element 8.

• the expression "integral at least in translation along the main first extension axis X" must be understood to mean that the insert 12 and first adjustment body 7 will always move together along the main first extension axis X when one of the two is pushed to translate along it and that they may possibly be able to move with respect to each other when one of the two is pushed to translate along a different axis, for example along the second extension axis Y.
• a first tilted surface 13 which is tilted with respect to the main first extension axis X and to the first lying plane ⁇ and is susceptible to being placed in abutment against the other between the thrust element 11 and the insert 12.
• the thrust element 11 is actuatable to translate along the movement direction W, with the first tilted surface 13 extended on one between the thrust element 11 and the insert 12 sliding against the other between the thrust element 11 and the insert 12, to move, through the insert 12, the first adjustment body 7 to translate in the first guide seat 6 along the first extension axis X.
• the hinge 1 in question when the hinge 1 in question is installed with the main first extension axis X of the first hinge element 2 oriented vertically and with the thrust element 11 placed below the insert 12 integral at least in translation along the first extension axis X with the first adjustment body 7, the weight force that is discharged from the wing onto the first adjustment body 7 is supported by the same thrust element 11 which generates a reaction force (unlike the hinges of the known art which only provided for a friction force), consequently making the same hinge 1 in question suitable for windows/doors/shutters having particularly heavy wings, for example around 80 kg or more.
• the placement of the thrust element 11 and the insert 12 (of which at least one is provided with the first tilted surface 13 to transform the translation of the thrust element 11 along the movement direction W into a translation of the insert 12 along the first extension axis X) advantageously allows the height of the wing to be adjusted with respect to the floor more easily with respect to the prior art, since the weight of the wing is discharged onto the thrust element 11 even during the height adjustment step, making it easier for operators to bring the wing to the desired height with respect to the floor.
• the first tilted surface 13 extends on the thrust element 11 and a second tilted surface 14 extends on the insert 12, which is parallel to the first tilted surface 13, directed towards the first tilted surface 13 and can be placed to abut against the first tilted surface 13.
• the thrust element 11 and the insert 12 are not in contact with each other only at one point, but along at least part or the entire extension of the first and second tilted surfaces 13, 14 depending on the position of the thrust element 11 along the movement direction W and of the insert 12 along the first extension axis X, thus avoiding a particularly high concentration of stresses on a restricted area.
• the thrust element 11 can be actuated to translate along the movement direction W, with the first tilted surface 13 sliding on the second tilted surface 14, to move, through the insert 12, the first adjustment body 7 to translate in the first guide seat 6 along the main first extension axis X.
• the aforesaid movement direction W is parallel to the second extension axis Y and orthogonal to the main first extension axis X and to the first lying plane ⁇ of the first internal side 3 of the first hinge element 2.

• the insert 12 is advantageously provided with two guide shoulders 17, which are extended projecting from the second tilted surface 14, carry the second tilted surface 14 interposed therebetween, are each provided with a corresponding fourth tilted surface 18 parallel to the second tilted surface 14 and are at least partially inserted in the guide grooves 15 of the thrust element 11 with the fourth tilted surfaces 18 capable of being placed in abutment against the third tilted surfaces 16.
• the thrust element 11 and the insert 12 cannot translate relative to each other parallel to the third extension axis Z, since the guide shoulders 17 of the insert 12 inserted in the guide grooves 15 of the thrust element 11 prevent such translations.
• the first tilted surface 13 of the insert 11 advantageously slides on the second tilted surface 14 of the insert 12 and the third tilted surfaces 16 of the guide grooves 15 of the thrust element 11 advantageously slide on the fourth tilted surfaces 18 of the guide shoulders 17 of the insert 12.
• the first external hull 5 is extended along the main first extension axis X between two opposite first ends 19 and the first adjustment body 7 is extended along the main first extension axis X between two opposite second ends 20, each of which is adjacent to a corresponding first end 19 of the first external hull 5.

• the insert 12 of the adjustment device 10 is preferably arranged at a respective second end 20 of the first adjustment body 7 adjacent to the first end 19 at which the thrust element 11 is substantially arranged and the second tilted surface 14 of the insert 12 is directed towards the first tilted surface 13.
• the second tilted surface 14 of the insert 12 is directed towards the first end 19 at which the thrust element 11 is substantially placed and in the opposite direction with respect to the bottom wall 21.
• the first hinge element 2 is provided with two fixing flanges 54, which are made in one piece with the first external hull 5, are each placed at a respective first end 19 of the aforesaid first external hull 5 and are each provided with one or more attachment holes 55 intended to be passed through by a corresponding attachment screw to fix the first external hull 5 to the wing or to the frame on which the corresponding containment housing is made.

• the fact that the thrust element 11 is substantially provided with only one degree of freedom to translate along the movement direction W means that the adjustment pin 22 and the thrust element 11 itself together form a screw-and-nut mechanism.
• the placement of the adjustment pin 22 which engages a hole in the nut screw hole 23 obtained on the thrust element 11 advantageously allows the height of the wing to be adjusted with respect to the floor in a particularly precise manner, since each rotation of the adjustment pin 22 around the movement direction W corresponds to a translation of the thrust elements 11 along this movement direction W equal to the pitch of the thread made on the adjustment pin 22.
• the first external hull 5 is provided with at least two positioning shoulders 42, each of which is provided with a contact surface opposite the contact surface of the other positioning shoulder 42 and parallel to the movement direction W and, furthermore, the thrust element 11 of the adjustment device 10 is inserted at least in part and substantially to size between the positioning shoulders 42 in a movable manner along the movement direction W.

• the portion of the adjustment pin 22 protecting from the engagement hole 24 on the first external side 4 is beveled to define the aforesaid enlarged retention section 25.
• the enlarged retention section 25 is defined by a washer welded to the portion of the adjustment pin 22 projecting from the engagement hole 24 on the first external side 4.
• the adjustment pin 22 is advantageously provided with an abutment shoulder 26 placed between the thrust element 11 and the bottom wall 21 and, furthermore, the adjustment device 10 is provided with elastic means 27 interposed between the bottom wall 21 and the enlarged retention section 25 in order to draw the abutment shoulder 26 in abutment against the bottom wall 21 (in particular against the step 44 of the aforesaid bottom wall 21) acting against the enlarged retention section 25.

• cup spring 47 as elastic means 27, it is possible to firmly maintain the abutment shoulder 26 in abutment against the bottom wall 21, since the cup spring 47 is generally provided with a particularly high rigidity with respect to that of other types of springs or elastic elements in general.
• the insert 12 of the adjustment device 10 is provided with a protruding portion 28, which protrudes along the main first extension axis X with respect to the corresponding second end 20 of the first adjustment body 7, and with a housing groove 29, which is made in a through manner along the movement direction W at the protruding portion 28 and is susceptible to being at least partially occupied by the adjustment pin 22.
• the placement of the housing groove 29 on the protruding portion 28 of the insert 12 means that, during the adjustment of the position of the first adjustment body 7 along the main first extension axis X, it is possible to translate the insert 12 between the thrust element 11 and the bottom wall 21 to such an extent that the housing groove 29 itself receives the adjustment pin 22 therein, thus preventing the adjustment pin 22 itself from limiting the maximum possible translation of the first adjustment body 7 along the main first extension axis X. Consequently, thanks to the housing groove 29, it is possible to obtain a particularly large maximum translation of the first adjustment body 7 along the main first extension axis X, while at the same time keeping the overall length of the first hinge element 2 along the first extension axis X as short as possible.
• the second tilted surface 14 is extended on the protruding portion 28 and the housing groove 29 is made in a through manner along the movement direction W at part of the second tilted surface 14 extending onto this protruding portion 28.
• the first guide seat 6 is extended along the third extension axis Z with a first width thereof and the first adjustment body 7 is provided, along the third extension axis Z, with a second width which is smaller than the first width, so that the first adjustment body 7 is slidable with respect to the first external hull 5 along the third extension axis Z.
• the first guide seat 7 of the first external hull 5 can be delimited along the third extension axis Z by one or two lateral sides 30 of the same first external hull 5, which extend projecting starting from the bottom wall 21, or from the material of the wing or frame which defines the containment housing in which the first external hull 5 of the first hinge element 2 is inserted.
• the insert 12 of the adjustment device 10 is preferably provided with a slotted hole 31, which is elongated along the third extension axis Z, and the adjustment device 10 is also provided with a fixing screw 32, which is placed to traverse the slotted hole 31 and is screwed into a corresponding threaded fixing hole 33 made on the first adjustment body 7.
• the first adjustment body 7 is provided with a lowered portion 51 at least at one of the second ends 20 thereof, the fixing hole 33 is made at the aforesaid lowered portion 51 and the insert 12 is provided with a fixing portion 52 placed in abutment against said lowered portion 51 and on which the aforesaid slotted hole 31 is made.
• the first adjustment body 7 is preferably provided with at least one positioning wall 53 extended projecting with respect to the lowered portion 51 and the fixing portion 52 of the insert 12 is also placed in abutment against the aforesaid positioning wall 52.
• the insert 12 of the adjustment device 10 can be made in a single body with the first adjustment body 7 (consequently not being able to adjust the pressure exerted by the wing in the closed position on the seal by moving the first adjustment body 7 along the third extension axis Z).
• the second adjustment body 41 of the second hinge element 8 can be slidable with respect to the second external hull 39, not only along the fifth extension axis T, but also along the sixth extension axis U, so as to be able to adjust the pressure exerted by the wing in the closed position on the frame seal.
• the second guide seat 40 must have a width along the sixth extension axis U which is greater than that of the second adjustment body 41 and the adjustment means of the second hinge element 8 must be placed to allow the position of the second adjustment body 41 to be set in the second guide seat 40 both along the fifth extension axis T and along the sixth extension axis U.
• the first hinge element 2 is provided with two adjustment devices 10, which are preferably mirror images of each other with respect to a plane orthogonal to the main first extension axis X.
• each adjustment device 10 is placed substantially at a respective first end 19 of the first external hull 5 and the first tilted surface 13 of each thrust element 11 is directed towards the bottom wall 21 and the second end 20 of the first adjustment body 7 adjacent to the first end 19 at which the respective thrust element 11 is substantially placed and, furthermore, the insert 12 of each adjustment device 10 is placed at a respective second end 20 of the first adjustment body 7 and is directed towards the first tilted surface 13 of the respective thrust element 11.
• the hinge 1 in question can be used for both right- and left-opening windows/doors/shutters since, advantageously having two mirrored adjustment devices 10, it will always be provided with a lower adjustment device 10 and an upper adjustment device 10 regardless of the orientation it has once installed with the main first extension axis X in the vertical position.
• the thrust element 11 of the upper adjustment device 10 is translated along the corresponding movement direction W away from the bottom wall 21 in order to allow the lower adjustment device 10 to set the position of the first adjustment body 7 itself by acting on the thrust element 11 thereof and, after having reached the desired height of the first adjustment body 7, the thrust element 11 of the upper adjustment device 10 is translated towards the bottom wall 21 until it abuts against the corresponding insert 12 to lock the first adjustment body 7 in position.
• the thrust element 11 of both adjustment devices 10 prevents, through the corresponding insert 12, the first adjustment body 7 from moving downwards along the first extension axis X and the thrust element 11 of the upper adjustment device 10 prevents, through the corresponding insert 12, the first adjustment body 7 from moving upwards along the first extension axis X.
