HINGE FOR THE CONTROLLED REVOLVING MOVEMENT OF A DOOR

DESCRIPTION

Field of application

The present invention is generally applicable to the technical sector of closing or damping / control hinges, and particularly relates to a hinge for the revolving movement of a door, in particular but not exclusively an armored door.

State of the art

As is known, closing or cushioning hinges generally comprise a movable element, usually fixed to a door, a leaf or similar, hinged on a fixed element, usually fixed to the supporting frame of these, or to a wall and / or to the floor.

More specifically, in the case of concealed hinges for armored doors or similar, the fixed element of the hinges is inserted inside a tubular support structure that includes a rear subframe anchored to a wall or similar support and a front frame anchored to the subframe.

The mobile element, then, generally includes a fixing wing that can be anchored to the door designed to come out of the tubular support structure in the open position and to re-enter completely inside the tubular support structure in the closed position.

Generally, these hinges are purely mechanical, and do not allow any type of adjustment of the opening angle of the door or in any case any control of the movement of the door itself.

Examples of such known hinges are illustrated in documents US5075928 and WO2010049860. The absence of control makes these hinges extremely dangerous, since due to the huge mass of the armored door there is the danger of the door being unhinged or bending of the tubular support structure to which the hinge is anchored.

Also due to the enormous mass of the armored door, the hinge tends to lose its initial position and / or to disassemble.

Furthermore, adjusting the door position is tiring and complicated. In addition, at least two operators are required to carry out the same.

Another recognized drawback of these hinges lies in the high friction that develops between the fixed and mobile element, which leads to premature wear and frequent breakages, with the consequent need for continuous training.

Presentation of the invention

The purpose of the present invention is to at least partially overcome the drawbacks encountered above, by providing a hinge of high functionality, construction simplicity and low cost.

Another object of the invention is to provide a hinge which allows to control the movement of the door in opening and / or closing.

Another object of the invention is to provide a sturdy and reliable hinge.

Another object of the invention is to provide a hinge with extremely limited dimensions.

Another object of the invention is to provide a hinge which ensures automatic closing of the door from the open door position.

Another object of the invention is to provide a hinge capable of supporting even very heavy doors and frames.

Another object of the invention is to provide a hinge which has a minimum number of constituent parts.

Another object of the invention is to provide a hinge capable of maintaining the exact closing position over time.

Another object of the invention is to provide a hinge which is safe.

Another object of the invention is to provide a hinge which is easy to install.

Another object of the invention is to provide a hinge which simplifies the maintenance and / or replacement of the same.

Another object of the invention is to provide a hinge which allows a simple adjustment of the door to which it is connected.

Another object of the invention is to provide a hinge that is reversible, that is, it can be used straight or upside down without changing its behavior.

These purposes, as well as others which will appear more clearly below, are achieved by a hinge having one or more of the characteristics described and / or claimed and / or illustrated herein.

Advantageous embodiments of the invention are defined in accordance with the dependent claims.

Detailed description of some preferred embodiments With reference to the aforementioned figures, the hinge according to the invention, generally indicated with 1, will be particularly useful for the possibly controlled rotating movement in opening and / or closing of a closing element D, such as for for example an armored door, which can be anchored to a stationary support structure, such as a wall, a floor or a ceiling.

In a preferred but not exclusive embodiment, as illustrated in FIGS. from 1 to 17c, the hinge 1 can be inserted concealed in a tubular support structure, which can be formed in a per se known way by a rear counterframe CF, which can be anchored to the wall W or similar support, and by a front frame F anchored to the counter frame CF.

In particular, in a first embodiment illustrated in FIGS. from 1 to 13d, the hinge 1 can be anchored to the frame F by means of the plate P1, kept in operative position by the screw means V1.

On the other hand, in a second embodiment illustrated in FIGS. from 14 to 17c, the hinge 1 can be configured as a retractable â € œanubaâ € hinge, anchored to the frame F by means of the plate P2.

In both embodiments, the hinge 1 can be retracted into the tubular support structure formed by the rear counter frame CF and the front frame F.

On the other hand, in FIGS. 18 to 33d illustrate some embodiments of the non-retractable hinge 1.

In particular, the embodiment illustrated in FIGS. from 18 to 25d it is a hinge of the "anuba" type suitable for being mounted externally to a door, for example an armored door, as shown for example in FIGS. from 20a to 21b.

On the other hand, FIGS. 26 to 33d illustrate hinges adapted to be mounted in view on the frame of a door. The embodiment illustrated in FIGS. 26 to 28c differs from that illustrated in FIGS. from 29 to 33d due to the fact that the latter has means for adjusting the position of the door when it is in the closed position.

The above embodiments have some common features or sets of features and some features or sets of features unique to certain embodiments. Unless otherwise specified, the common characteristics will be referred to generically with a single identification number, and the peculiar characteristics of one or more embodiments will be specified.

Conveniently, the hinge 1 may comprise a fixed element 10, which can be fixed to the stationary support W, for example by means of the frame F or the counterframe CF, on which a movable element 20 rotatable around a longitudinal axis X, which can be substantially vertical, between an open position, illustrated for example for the first embodiment above in FIGS. 3a, 3b, and a closed position, illustrated for example for the same embodiment in Figures 2a and 2b.

Advantageously, the fixed element 10 may include a box-shaped hinge body 11 which can be anchored to the stationary support W, while the mobile element 20 may include means for fixing 21 to the door D.

In the embodiments of the hinge 1 illustrated in FIGS. from 1 to 17c the box-shaped hinge body 11 can be hidden inside the tubular support structure formed by the rear subframe CF and the front frame F, while the fixing means 21 can be defined by a fixing wing designed to come out of the tubular support structure in the open door D position, as illustrated for example in FIGS. 16c and 16d, and to return inside the same in the closed position of the door D, as for example illustrated in Figures 16a and 16b.

In particular, in the first embodiment illustrated in FIGS. from 1 to 13d the fixing wing 21 can be configured according to the teachings of the Italian patent application VI2012A000156, in the name of the same Applicant, and can therefore have a substantially â € œCâ € shape, with a central portion 22 able to be connected to the door D by means of the fixing bracket 30 and a pair of end portions 23, 23â € ™ mutually facing each other and operatively connected with the box-like body 11.

On the other hand, the fixing wing 21 of the hinge 1 of the embodiment illustrated in FIGS. from 14 to 17c it is rotatably connected to the hinge body 11 by means of the pin 40, which will be better described later on.

Also in the embodiment illustrated in FIGS. from 18 to 25d the fastening means 21 to the door D are defined by a fastening wing, rotatably connected to the hinge body 11 by the pin 40.

In the embodiments illustrated in FIGS. from 26 to 33d, on the other hand, the fastening means 21 are defined by a pair of cheeks 24, 24â € ™ suitable for mutually cooperating to lock the door D.

In all embodiments of the hinge 1 illustrated in FIGS. from 1 to 33d, the hinge body 11 may include a through seat 12 defining the X axis inside which the pin 40 is inserted with minimum play, which can be connected to the fastening means 21.

Depending on the embodiment of the hinge 1, the pin 40 will have one or both ends 41 mutually connected with the fastening means 21.

In this way, the pin 40 will be integrally movable with the door D between the opening and closing positions. Thanks to this characteristic, the hinge 1 will be able to support even very heavy doors D without misalignments or changes in behavior.

Conveniently, respective anti-friction elements 13, such as bearings, as in the embodiments illustrated in FIGS, can be placed at the ends of the through seat 12 of the box-like body 11. 1 to 25d, or bushings, as in the embodiments illustrated in FIGS. from 26 to 33d.

This will allow the mobile element 20 to rotate around the X axis with minimum friction, so that the hinge 1 is able to move even very heavy doors D.

The hinge body 11 may internally include a working chamber 14 defining a second axis Y substantially perpendicular to the first axis X defined by the through seat 12 for the pin 40.

Conveniently, the pin 40 may include cam means 50 rotating around the X axis, while the working chamber 14 may include cam follower means 60 interacting with the former to move smoothly along the Y axis between a first and a second end-of-stroke position, illustrated for example in Figures 7b and 9b.

The cam follower means 60 may include an elastic contrast element adapted to elastically contrast the thrusting force imparted by the cam means. For a non-limiting example, the elastic contrasting element may include, respectively, a spring, a nitrogen cylinder or a portion made of polymeric material.

In a preferred but not exclusive embodiment of the hinge 1, the elastic contrasting element can be constituted by an elastomer body 61, which can have a plate-like, discoidal or cylindrical shape.

Advantageously, the elastomeric body 61 can be made of compact type polyurethane elastomer, for example Vulkollan®. Conveniently, the elastomer may have a Shore A hardness between 50 ShA and 95 ShA, preferably between 70 ShA and 90 ShA. More preferably, the elastomeric body 61 may have a Shore A hardness of 80 ShA.

The use of elastomer instead of the classic spring will allow to develop a very high force, when braking and / or pushing, in very limited spaces. The stroke of the elastomeric body 61 along the Y axis, in fact, could be a few millimeters, for example 4 mm.

Furthermore, the elastomeric body 61 will allow to obtain a highly efficient braking effect, for example in opening as in the embodiments illustrated in FIGS. from 1 to 25d, in a purely mechanical hinge, without the use of oil or anyway means of hydraulic damping.

In these embodiments, in fact, following the opening of door D, the elastic contrast element 61 will pass from the first to the second end-of-stroke position and will remain in this last position until the door is closed by a user, so that the hinge 1 is a brake control hinge in opening.

In the embodiments illustrated in FIGS. from 26 to 33d, on the other hand, the elastomeric body 61 is used in thrust, in order to make the cam 50 and the cam follower 60 interact reciprocally and maintain the door stop positions, as better explained later on.

Advantageously, moreover, the cam follower means 60 may include an interface element 62 having a first end 63â € ™ interacting with the elastic contrast element 61 and a second end 63â € ™ â € ™ interacting with the cam means 50 .

In the embodiments illustrated in FIGS. from 1 to 25d, the interface element 62 may have a substantially "C" shape with a central elongated portion 64 defining a third longitudinal axis Z substantially parallel to the X axis and perpendicular to the Y axis and a pair of transverse appendages d 'end 65', 65 '' substantially perpendicular to the X axis and parallel to the Y axis.

Both the elongated central portion 64 and the transverse end appendages 65 ', 65' 'may include respective operating surfaces 66, 67', 67 '' placed in correspondence with the front end 63 '', the function of which will be explained later. .

In the embodiment illustrated in FIGS. from 26 to 28c, the interface element 62 may have a generally cylindrical shape, and be configured as a pusher.

In the embodiment illustrated in FIGS. from 29 to 33d, the interface element 62 may be composed of two pieces, a cylindrical pusher 68 'and a pressing disk 68' 'inserted in a bushing 70, the function of which will be better explained later.

Conveniently, the pin 40 may include the cam means 50, so that the latter rotate integrally with the former around the X axis.

Advantageously, then, the cam means 50 may include one or more cam elements adapted to interact with the cam follower means 60.

More particularly, in the embodiments illustrated in FIGS 1 to 9c, 14 to 17c and 26 to 33d the cam means 50 may include a single cam element, while in the remaining embodiments the cam means 50 may include two cam elements ..

The cam elements may have a different configuration according to the embodiment.

For example, in the embodiments illustrated in FIGS. from 1 to 9c and from 14 to 17c, the single cam element can be defined by a plate-like body 51 removably insertable transversely in a seat 42 of the pin 40 so that a portion of the first protrudes from the second. This configuration simplifies the assembly of hinge 1.

On the other hand, the plate-like body 51 can be integrated into the pin 40 in an irremovable manner.

Conveniently, the plate-like body 51 may have a front peripheral edge 53 adapted to interact with the interface element 62, for example in correspondence with the operating surface 66. For this purpose, the front peripheral edge 53 can be suitably rounded.

In this way, the interface element 62 will progressively compress the elastomeric body 61 following the opening of the door D. The elastomeric body 61, moreover, may be susceptible to remain in the elastomeric configuration until the door D is closed. part of a user. In other words, the hinge 1 will be elastically braked in opening.

In these embodiments, the hinge 1 can be configured so that the cam element 51 meets the operating surface 66 after an angular rotation of the door D, for example 45 ° as particularly illustrated in FIGS. 7b and 8b. Following the interaction with the interface element 62, the cam element 51 will compress the elastomeric body 61, so that the hinge is mechanically braked in opening for the subsequent angular rotation, for example the following 45 ° as particularly illustrated in FIGS.8b and 9b. In other words, the first angular rotation will be free, ie not braked, while the subsequent angular rotation will be braked by the braking action of the elastomeric body 61.

On the other hand, in the embodiments illustrated in FIGS. from 26 to 33d, the single cam element can be defined by a plurality of flat faces 43 obtained in correspondence with the central portion of the pin 40. In particular, the flat faces 43 can be three in number, perpendicular to each other to define as many door locking positions D, in the closed position and in the open position in both possible directions.

In the embodiments illustrated in FIGS. from 10a to 13d and from 18 to 25d two cam elements may be provided, in particular a pair of first cam elements 52â € ™, 52â € ™ â € ™ adapted to interact with the operating surfaces 67â € ™, 67â € ™ interface element 62 and a second cam element consisting of plate-like element 51 able to interact with the operative surface 66.

The first cam elements 52â € ™, 52â € ™ â € ™ can be defined by a pair of substantially flat faces obtained on the external surface 44 of the pin 40, in longitudinally offset positions so as to come into operational contact with the planar operating surfaces 67â € ™, 67â € ™ â € ™ of the interface element 62.

Conveniently, the cam means 50 and the follower means 60 can be configured in such a way that the substantially flat faces 52â € ™, 52â € ™ â € ™ and the operating surfaces 67, 67, are substantially parallel and mutually in contact when the door D is in the closed position, as for example illustrated in FIGS 11a to 11d, and are substantially perpendicular to each other and mutually spaced when the door D is in the open position, as for example illustrated in FIGS 13a to 13d.

The plate-like element 51, moreover, will be able to define a plane Ï € substantially perpendicular to the substantially flat faces 52â € ™, 52â € ™ â € ™.

In this way, it will be possible to obtain total control over door D during the opening phase, for all its angular rotation.

For a first section of angular rotation, in fact, the substantially flat faces 52â € ™, 52â € ™ â € ™ and the operative surfaces 67â € ™, 67â € ™ â € ™ will interact with each other to partially compress the elastomeric body 61, bringing it from the rest or start position to an intermediate compressed position. For the next section of angular rotation of the gate D, the plate-like element 51 and the operative surface 66 of the interface element 62 will interact, so as to further compress the elastomeric body 61, bringing it from the intermediate compressed position to the fully compressed or end-of-stroke position.

This allows to gradually compress the elastic contrast element, so as to obtain a braking effect for the entire angular rotation of the door D.

The embodiment of hinge 1 illustrated in FIGS. 11a to 13d can open only in one direction, while the embodiment illustrated in FIGS. from 18 to 25d it can open in both opening lines. This also allows for an ambidextrous hinge, which means that it can be used both straight and inside out. For this purpose, the external surface 44 of the pin 40 may include a respective pair of operating surfaces 52â € ™, substantially perpendicular to each other and connected to each other.

In this embodiment, moreover, the particular shape of the operating surfaces 52â € ™ will allow to totally control the movement of the door D from the closed position to the one completely open at 180 °.

In the embodiments of hinge 1 illustrated in FIGS. from 1 to 13d, it is possible to adjust the opening angle of door D.

For this purpose, an adjustment dowel 80 may be provided transversely inserted in the hinge body 11 with a first maneuvering end 81 accessible by a user to adjust the penetration of the first 80 through the relative wall of the second 11 and an opposite end 82 suitable for to come into contact with the plate-like element 51.

By acting appropriately on the maneuvering end 81 of the grain 80 it will be possible to adjust the opening angle of the door in a simple and rapid way, so that the door D cannot impact against the stationary support W.

Advantageously, moreover, in the embodiment of hinge 1 illustrated in FIGS. from 18 to 25d it is possible to adjust the prestress of the elastic contrast element, which in this embodiment is constituted by the elastomeric body 61.

For this purpose, a slide 90 sliding along the Y axis may be provided with a first end 91 'interacting with the elastomeric body 61 and a second end 91' 'interacting with a pair of adjustment dowels 92.

By acting appropriately on the grains 92, therefore, the user will be able to adjust the sliding of the slide along the Y axis, in order to adjust the prestress of the elastic contrast element as needed, and consequently the force with which it interacts with the cam means and, therefore, which it develops when the door is opened and / or closed.

This is particularly advantageous with the elastomeric body 61, in which a prestress of even a single millimeter corresponds to an extremely high braking force.

The hinge 1, in addition to being extremely effective and functional, is also extremely simple to assemble.

For example, with reference to the embodiment illustrated in FIGS. from 1 to 13d, the hinge body 11 may have, in addition to the through seat 12 intended to contain the pin 40, two through openings 15, 16 to make the working chamber 14 accessible from the outside.

In particular, the first through opening 15 is intended to allow the insertion of the cam follower means 60 into the working chamber 14 and the second opening 16 is intended to allow the insertion of the cam means 50 into the same working chamber 14. .

The two through openings 15, 16 define as many axes which are placed perpendicular to each other. In particular, the first through opening defines an axis coincident with the Y axis, while the second opening 16 defines a Y 'axis perpendicular to both the Y axis and the X axis.

In practice, both the cam means 50 and the cam follower means 60 can be removably inserted into the working chamber 14 by sliding along the plane defined by the Y, Y 'axes, perpendicular to the X axis.

This is particularly advantageous if it is necessary to change the elastic contrast element 61, for example to insert a softer or harder one in order to vary the action of the hinge 1 during braking, or to change the plate-like element 51, for example to insert one of a different configuration to vary the braking action of the hinge 1.

The embodiment of the concealed "anuba" type hinge 1 illustrated in FIGS. from 14 to 17c, in addition to the characteristics and advantages indicated above, it is particularly advantageous since thanks to it it is possible to adjust the position of the door D in three dimensions, i.e. both in height and in a plane substantially parallel to the floor as illustrated for example in FIG.16c.

The hinge 1 may include a fixed lower half-hinge 10 with a box-shaped hinge body 11 which can be hidden inside the tubular support structure F, CF and a movable upper half-hinge 20 which includes the fixing wing 21 which can be anchored to the door D .

As particularly illustrated in FIGS. from 16a to 16d, the fixing wing 21 is designed to come out of the tubular support structure F, CF in the open position, illustrated in FIGS.

16c and 16d, and to return inside the tubular support structure F, CF in the closed position, illustrated in Figures 16a and 16b.

The fixing wing 21, in fact, may include a first portion 25 'adapted to receive the pin 40 and a second portion 25' 'adapted to receive the fixing bracket 30 and to allow its adjustment along the directions d, d', as illustrated in FIG.15b.

Conveniently, the fixing bracket 30 may have a first plate-like portion 31 operably anchored to the first portion 25 'of the fixing body 24 monolithically coupled with a second plate-like portion 32, in turn connectable to the door D by means of suitable screws which can be inserted in the holes 33.

The operative connection between the first portion 25 'of the fixing body 24 and the first plate-like portion 31 of the fixing bracket 30 can take place by means of suitable screws 34 which can be inserted through the holes 26 of the fixing body 24 and the openings 35 of the fixing bracket 30 and lockable in suitable locking elements 36.

By acting appropriately on the screws 34 it will be possible to make the fixing bracket 30, and therefore the door D, move along the direction d '. By appropriately loosening these screws 34, in fact, it will be possible to make the fixing bracket 30 translate for a stroke equal to the length L of the openings 35 in which the screws 34 themselves are inserted.

The translation along the vertical direction d will be ensured by the grains 37â € ™, 37â € ™ â € ™ inserted through the second portion 25 '' of the fixing wing 21, between which lies the first plate-like portion 31 of the fixing bracket 30. As mentioned above, the latter is secured to the former by means of screws 34.

The dowels 37â € ™, 37â € ™ â € ™ can be operated after loosening the screws 34, which will allow the translation of the fixing bracket 30 with a stroke equal to the height H of the openings 35 in which the screws 34 are inserted.

To allow the translation of the hinge 1 along the direction of â € ™, the hinge body 11 can be mounted movably on an anchoring plate 100, which can be anchored to the tubular support structure F, CF by means of the screws 101.

For this purpose, a counterplate 102 may be provided, which can be coupled to the hinge body 11 by means of the screws 103 to define a gap 104 between them, in which the anchoring plate 100 is housed. it may include two side abutment surfaces 105â € ™, 105â € ™ â € ™.

In the alternative embodiment illustrated in FIGS. 17h and 17i, the counterplate 102 can be integrated into the hinge body 11, ie the two parts can be made together in one piece. This allows for a cheaper hinge 1.

The screws 101 will be engageable in the anchoring plate 100 passing through the slots 106 of the counterplate 102.

By acting appropriately on the screws 101 it will be possible to make the assembly between the hinge body 11 and the counterplate 102, and therefore the door D, move along the direction of '. By appropriately loosening these screws 101, in fact, it will be possible to make the assembly between the hinge body 11 and the counterplate 102, and therefore the hinge 1, translate for a run equal to the length Lâ € ™ of the slots 106 in which the screws 101 themselves are inserted and / or the distance between the lateral abutment surfaces 105â € ™, 105â € ™ â € ™ of the interspace 104.

The embodiments of the "Anuba" type hinge 1 illustrated in FIGS. 14 to 25d may be suitable for minimizing friction between the fixed half-hinge 10 and the mobile half-hinge 20.

For this purpose, the upper end 110 'of the seat 12 may include a respective upper annular housing 111' capable of accommodating a respective upper anti-friction element 13 ', for example a bearing.

As particularly visible in FIGS. 17d and 17e, the pin 40 may include an upper radial expansion 112 ', for example a flange, with an upper operating surface 113' intended to come into contact with the fixing wing 21 and a lower operating surface 113â € ™ â € ™ intended to remain facing the upper annular housing 111â € ™.

Advantageously, the upper annular housing 111â € ™ and the upper anti-friction element 13â € ™ can be mutually configured so that the lower operating surface 113â € ™ â € ™ of the upper radial expansion 112â € ™ is susceptible to go into contact with the upper anti-friction element 13â € ™. In this way, the pin 40 will be able to rotate on the upper anti-friction element 13â € ™ while remaining mutually spaced from the hinge body 11.

For this purpose, the internal diameter D1 of the upper annular housing 111â € ™ could be substantially equal to the external diameter D2 of the upper anti-friction element 13â € ™, while the height h2 of the latter may be slightly higher than the height h1 of the first, for example a few tenths of a millimeter.

Furthermore, the lower end 110â € ™ â € ™ of the seat 12 conveniently includes a lower annular housing 111â € ™ â € ™ capable of accommodating a respective lower anti-friction element 13â € ™.

The lower end 41 of the pin 40 may include a blind axial hole 114 suitable for accommodating a locking screw 115. A pressure element 112â € ™ â € ™, for example a washer, may also be provided to be interposed between the locking screw 115 and the lower anti-friction element 13â € ™ â € ™ to define a lower radial expansion. Advantageously, the latter may include an upper operative surface 116 destined to remain facing the lower annular housing 111â € ™ â € ™.

The latter, the lower anti-friction element 13â € ™ â € ™ and the pin 40 can be mutually configured so that the upper operative surface 116 of the pressing element 112â € ™ â € ™ is capable of abutting against the pin 40 and remain spaced from the lower anti-friction element 13â € ™ â € ™.

In this way, any constraint reactions that develop during the rotation of the pin 40 at its lower end 41 will be absorbed by the lower anti-friction element 13â € ™ â € ™.

This will prevent the pin 40 from slipping out of its seat 12 and / or the pin 40 itself from being out of alignment.

To minimize friction between the lower fixed half-hinge 10 and the upper mobile hinge 20, the internal diameter D3 of the lower annular housing 111â € ™ could be substantially equal to the external diameter D4 of the lower anti-friction element 13â € ™ , while the external diameter D5 of the pressing element 112â € ™ â € ™ may be slightly less than the internal diameter D3 of the lower annular housing 111â € ™ â € ™.

Conveniently, then, the height h3 of the latter could be substantially equal to the sum of the height h4 of the lower anti-friction element 13â € ™ and the height h5 of the pressure element 112â € ™.

Advantageously, the upper and lower anti-friction elements 13â € ™, 13â € ™ â € ™ can be made up of axial-radial bearings, in order to better discharge both the axial and radial stresses due to the weight of the door D and / or to the related binding reactions.

In the embodiment of the hinge 1 illustrated in FIGS. from 26 to 33d it will be possible to adjust the position of the movable element 20 in the position of door D closed.

For this purpose, a bushing 70 may be provided with a central hole 71 in which the cylindrical pusher 68 'can be housed. Bushing 70 may include a tubular portion 72 having an outer diameter DB and height HB. Furthermore, the bushing 70 may have substantially flat upper and lower surfaces 73 ', 73' ', and peripheral tapers 74', 74 ''.

On the other hand, the working chamber 14 may include a first tubular portion 17 'having a first internal diameter DC1 and a second portion 17' of generally rectangular shape, transversal dimension DC2 and height HC.

The bushing 70 can be inserted into the working chamber 14 with the tubular portion 72 positioned in correspondence with the second portion 17 '' of the working chamber 14 itself.

The height HB of the portion 72 of the bushing 70 may be substantially equal to the height HC of the second portion 17 '' of the working chamber 14.

The connecting portion 17 '' 'between the two portions 17' and 17 '' of the work chamber 14 can be suitably rounded, as well as the corresponding operating portion 75 of the bushing 70.

Thanks to this configuration, the bush 70 will be free to translate transversely once inserted into the working chamber 14. The stroke of this translation will be defined by the difference between the external diameter DB of the portion 72 of the bush 70 and the internal diameter DC2 of the portion 17 '' of the working chamber 14. During this translation, the bushing 70 will be horizontally guided by the sliding of the upper and lower surfaces 73 ', 73' 'substantially flat on the walls 18', 18 '' of the portion 17 '' of the working chamber 14, also flat.

To adjust this translation, the adjustment dowels 19 ', 19' 'acting on the tapers 74', 74 '' can be provided. In practice, the adjustment dowels 19 ', 19' 'will act in a substantially vertical direction, and the inclined planes defined by the tapers 74', 74 '' will transmit the horizontal component of the thrust force to the bushing 70, causing it to be translated in the portion 17 '' of the working chamber 14.

The connecting portions 17 '' 'of the working chamber 14 and the corresponding operating portion 75 of the bush 70 will then cooperate with each other to allow the partial rotation of the bush 70, so as to vary the inclination of the Y axis and with this is the closed door position, as particularly illustrated in FIG.33c.

In this embodiment, the shape of the cam means 50 will determine the stroke of the elastomeric body 61. In particular, this stroke may be between 1 mm and 5 mm, and preferably between 1 mm and 3 mm.

From what has been described above, it is evident that the hinge 1 achieves the intended purposes. The hinge 1 is susceptible of numerous modifications and variations. All the details can be replaced by other technically equivalent elements, and the materials can be different according to the requirements, without departing from the scope of protection of the invention defined by the attached claims.
