Description

The invention relates to the field of articulation systems for joinery, in particular articulation systems comprising a male hinge and a female hinge, one of the hinges being intended to be made integral with a frame of the carpentry and the another hinge being intended to be made integral with an opening of the joinery.

Such articulation systems are used in particular for the articulation of doors or windows in the building. In known manner, one of the problems is to be able to easily adjust the position of the opening relative to the frame in the direction of the hinge axis, that is to say generally the vertical direction. This position adjustment can be made by adjusting the position of the hinges on the sash or the frame. However, this possibility of adjustment is not easy to implement. Also, there are systems which make it possible to adjust the relative position of the hinges according to the direction of the articulation axis, without requiring the displacement of one or the other of the hinges relative to the leaf or the frame on which it is fixed.

Document FR-2,993,299 describes such an articulation system. In this articulation system, the male hinge comprises an articulation rod which comprises an upper articulation section and a threaded lower section, the latter being screwed into a threaded cavity of the main body of the male hinge. The main body has an end for fixing the male hinge to its joinery element. Between these two sections, the articulation rod has a radial flange which forms an annular abutment surface, which is intended to cooperate with an annular abutment surface corresponding to the female hinge to determine, in service, the relative position of the two hinges along the direction of the hinge axis. In this exemplary embodiment, a sleeve comprising a tubular body is interposed between the articulation axis and the female hinge, this sleeve comprising a radial collar which comes to be interposed longitudinally between the two abutment surfaces of the two hinges, such so that the latter cooperate indirectly, via the radial collar of the sleeve. In such an articulation system, it is understood that, by screwing or unscrewing the articulation rod relative to the main body, one can modify the relative position of these two elements in the longitudinal direction and one can therefore adjust the longitudinal position of the abutment surface of the male hinge relative to the main body, therefore relative to the joinery element on which the male hinge is fixed. However, except in an extreme position retracted downward, this adjustment reveals part of the threaded section of the articulation rod, which can be unsightly. For this, the system of document FR-2,993,299 comprises a set of cylindrical covers which are intended to be mounted each on the corresponding hinge. The only role of these covers is therefore to conceal the threaded section of the articulation rod when the latter is in an advanced position.

The invention therefore aims to provide a hinge system in which it is possible to adjust the relative longitudinal position of the two hinges, in a simple, aesthetic, and inexpensive.

To this end, the invention provides a male hinge for a hinge system comprising a male hinge and a female hinge, of the type in which the male hinge comprises:

- A hinge rod with a longitudinal axis capable of being engaged at least in part in one eye of the female hinge to form an articulation between the two hinges around an axis of articulation;

- The adjustment piece can comprise two guide sections, which can be cylindrical around the articulation axis, which can be offset longitudinally and which are each received in a guide ring of the support end of the main body. The adjustment section of the adjustment piece can then be arranged longitudinally between the two guide sections.

- The adjustment piece can comprise a single guide section which can be cylindrical around the articulation axis, and which can be received in a guide ring of the support end of the main body.

- The adjustment piece may comprise, at a rear longitudinal end, a form of coupling capable of cooperating with a tool for controlling the rotation of the adjustment piece.

- The shirt can be movable longitudinally with respect to the adjustment piece between at least an advanced position and a retracted position.

- an eye in which the articulation rod of the male hinge is engaged to form an articulation of longitudinal axis between the two hinges; and

- A stop surface which cooperates directly or indirectly with the adjustable stop surface of the male hinge to determine a relative service position in the longitudinal direction between the two hinges.

Such an articulation system can comprise a washer which is interposed between the adjustable abutment surface of the male hinge and the corresponding abutment surface of the female hinge.

Such an articulation system can comprise a sheath which is slidably mounted on the articulation rod, which has a radial collar interposed between the adjustable abutment surface of the male hinge and the corresponding abutment surface of the female hinge. In this case, it may further comprise a washer which is interposed between the radial collar of the sleeve and the adjustable abutment surface of the male hinge.

Is illustrated in the figures a hinge system 10, comprising a male hinge 12 and a female hinge 14, intended to ensure the articulation between two joinery elements 16, 18. Two embodiments of the invention will be described respectively in relation to Figs. 1 to 8 and with Figs. 9 to 16. Essentially, the description applies to the two embodiments. The joinery element 16 may be a frame, for example the frame of a door. The joinery element 18 may be an opening, for example a door. The joinery elements 16, 18 can be made of all usual materials, for example wood and / or metal and / or plastic material, etc. In the exemplary embodiments, the male hinge 12 is intended to be arranged below the female hinge, but a reverse configuration is possible. Similarly, the male hinge 12 can be linked to the frame while the female hinge 14 is then linked to the opening, but a reverse configuration is also possible. Similarly, in the exemplary embodiments, the articulation axis A1 formed by the articulation system 10 is vertical, but other orientations are possible.

In the exemplary embodiments of the invention, the female hinge 14 is perfectly conventional and has a main body which comprises a tubular body 20 of revolution along the longitudinal articulation axis A1. The tubular body 20 delimits a cylindrical cavity 22 d axis A1, commonly called the eye of the female hinge or knot of the female hinge. As will be seen later, this cavity 22 is intended to receive an articulation rod of the male hinge to determine the articulation around the axis A1. The tubular body 20 is arranged at the end of a transverse arm 24 of the main body of the female hinge, the other end of which is linked to a fixing end 26 of the main body to allow the fixing of the female hinge 14 on the corresponding joinery element 18, here on a frame. The fixing end 26 is here produced, in a known manner, in the form of a plate elongated in the longitudinal direction and pierced with several holes, preferably chamfered, to allow fixing by screwing the plate flat on the joinery element 18, here on the edge of a door. In the examples illustrated, the main body of the female hinge 14 is made in one piece from a metal plate. The tubular body 20 for example is produced by folding and winding the metal plate around the axis A1. Of course, the female hinge 14 can be produced according to all the traditional techniques for this kind of parts including, for all or part , made of plastic. In particular, the fixing end 26 can be configured as a function of the joinery element on which the hinge is to be fixed. Likewise, the transverse arm 24 here has the form of a plate element, or blade, which extends transversely between the fixing end 26 and the tubular body 20 and which extends longitudinally over the entire length of the body. tubular

20. As a variant, the main body could be produced in the form of several parts assembled together, preferably without relative movement between them in service configuration. For example, the transverse arm 24 could be made in the form of one or more transverse bars. In the examples illustrated, the cavity 22 delimited by the tubular body 20 is open at the two longitudinal ends of the tubular body. The lower opening (relative to the orientation of the figures) of this cavity 22 is therefore bordered by a transverse annular surface 28 which, as will be seen below, is intended to form a stop surface for cooperating directly or indirectly with an abutment surface of the male hinge 12, this in order to determine a relative service position, in the longitudinal direction of the articulation axis A1, between the male hinge 12 and the female hinge 14. In the second embodiment example , a cap 21 is provided which covers the tubular body. This cap

21, in the form of a tube whose lower end is open and the upper end closed, is split over at least part of its length, with a slot opening into the lower end. In the service position, the slot allows the transverse arm 24 to pass.

The male hinge 12 comprises a main body 30 which has an end 32 for fixing the male hinge 12 to a joinery element 16, a transverse arm 34 and a support end 36 for an articulation rod 38, cylindrical with an axis longitudinal Al, which, in the exemplary embodiments, is produced in the form of a piece independent of the main body 30 of the male hinge 12. The longitudinal axis of the rod 38 is considered to coincide with the axis of articulation Al of the articulation system 10.

The articulation rod 38 of the male hinge 12 extends longitudinally towards the front relative to the support end 36. The notion of front along the longitudinal axis, and consequently that of rear, is a arbitrary notion. In the examples illustrated, the front corresponds to the vertical direction upwards while the rear corresponds to the vertical direction downwards, but this is a particular case related to the respective orientation of the two hinges , the male hinge 12 being here arranged below the female hinge 14. In known manner, the articulation rod 38 is intended to be engaged at least partially in the eye 22 of the female hinge to form a joint of longitudinal axis A1 between the two hinges 12, 14. In the examples illustrated, the articulation rod 38 is fixed in translation along the longitudinal axis A1 with respect to the support end 36 of the main body 30.

One or more of the three parts of the main body 30 of the male hinge 12 could be produced in the form of an independent part assembled with the rest of the body, preferably without relative movement in service configuration. In the examples illustrated, the fixing end 32 and the arm 34 are formed by a plate-shaped element which extends in a plane parallel to the longitudinal axis A1 and to a direction transverse to this axis A1. In the examples illustrated, the fixing end 32 is intended to be engaged in a corresponding housing of the joinery element 16, or to be applied to a surface of the joinery element, and to be fixed thereto, so not shown, for example by welding or by one or more screws, one of these screws possibly also forming an anti-unhooking pin. The fixing end 32 can take any known form for fixing a hinge to a joinery element. At the opposite transverse end of the transverse arm 34, the support end 36 is here configured to form, in the first embodiment illustrated in FIGS. 1 to 8, two guide rings 40 having both for their axis the longitudinal axis of articulation A1. In the embodiment of FIGS. 9 to 16, there is provided a single guide ring 40 having as its axis the longitudinal articulation axis A1. Each ring 40 is here produced by a plate element which extends the plate of the transverse arm and which is wound around a tube around the axis A1. The tube formed by each ring 40 is not necessarily closed 360 ° around the axis A1. In the first embodiment illustrated in FIGS. 1 to 8, the two guide rings 40 are coaxial and aligned along the longitudinal axis of articulation A1, but they are offset from one another along this axis to provide a longitudinal space between them.

According to one aspect of the invention, the male hinge 12 comprises an adjustment piece 42 which is mounted movable in rotation about the longitudinal axis of articulation Al, and fixed in translation along the longitudinal axis of articulation Al, on the support end 36 of the main body 30. The adjustment piece 42 comprises an adjustment section 44 which has an external cylindrical surface with a longitudinal axis A1 comprising an external thread.

Furthermore, the male hinge 12 comprises a jacket 46 which has an internal cylindrical surface, of axis Al, comprising a longitudinal internal thread 48 which cooperates with the external thread of the adjustment section 44 of the adjustment piece 42. The jacket 46 is a separate part with respect to the adjusting part 42, to the main body 30 and to the articulation rod 38. As will be seen in more detail below, the jacket 46 carries the abutment surface 50, complementary to the surface stop 28 of the female hinge 14, for, in service, determining the relative position of the two hinges in the longitudinal direction, by direct or indirect contact of the two surfaces.

In the first example illustrated in Figures 1 to 8, the internal thread 48 of the jacket 46 extends in the direction of the hinge axis A1, over the entire length of the jacket. In the second example illustrated in FIGS. 9 to 16, it extends over only a section of the jacket 46, for example a section of reduced diameter forming a section for adjusting the jacket. In this second example illustrated in FIGS. 9 to 16, the adjustment section of the jacket on which the internal thread 48 is formed is a lower section of the jacket 46.

By the effect of the cooperation of their respective threads 48, 44, the jacket 46 is movable longitudinally relative to the adjustment piece 42, by screwing / unscrewing effect, depending on their relative rotation, between at least one advanced position illustrated respectively in FIGS. 7 and 15, and a retracted position illustrated in FIGS. 8 and 16. This relative position is dependent on the degree of screwing or unscrewing of the two parts. Figures 6 and 14 illustrate an intermediate position between the forward and backward positions. As explained above, the adjustment piece 42 is fixed relative to the main body 30 of the male hinge 12 in the direction of the hinge axis A1.

Preferably, the adjustment piece 42 comprises at least one transverse annular abutment surface which cooperates directly or indirectly with a bearing surface of the support end 36 of the main body 30 of the male hinge 12 to longitudinally block the workpiece. adjustment 42 relative to the main body 30.

In the first example illustrated in Figs. 1 to 8, the threaded adjustment section 44 of the adjustment piece is arranged between two guide sections 52, cylindrical with axis Al, of the adjustment piece 42. In other words, the guide sections 52 extend, longitudinally on either side, the adjustment section 44, and are therefore offset in the longitudinal direction of the axis Al. In this embodiment, the guide sections 52 are of diameter less than the diameter of the thread of the section of adjustment 44 and are received in the guide rings 40 of the main body 30 so as to provide rotational guidance of the adjustment piece 44, about the axis Al, relative to the main body. It is therefore understood that the adjustment section 44 of the adjustment piece 42 is received longitudinally between the two guide rings 40. Preferably, the length of the adjustment section 44 is equal to or slightly less than the spacing of the two rings 40 of so as to be received between the two rings. The external diameter of the adjustment section 44 is greater than the internal diameter of the two guide rings 40, therefore greater than the diameter of the guide sections 52, so as to form, at each longitudinal end of the adjustment section 44, a transverse annular surface of stop 43 which cooperates with a face 45 opposite the corresponding guide ring 40 for immobilizing the adjusting part 42 in the longitudinal direction relative to the main body 30. In the illustrated case, immobilization is ensured in both directions from this direction.

In the second example illustrated in Figs. 9 to 16, the threaded adjustment section 44 of the adjustment piece is arranged below a single guide section 52, cylindrical with axis Al, of the adjustment piece 42. The guide section 52 is of smaller diameter to the diameter of the thread of the adjusting section 44 and is received in the guide ring 40 of the main body 30 so as to ensure a guiding in rotation of the adjusting piece 44, about the axis Al, relative to the main body . It is therefore understood that the adjustment section 44 of the adjustment piece 42 is received longitudinally below the guide ring 40. The external diameter of the adjustment section 44 is greater than the internal diameter of the guide ring 40, therefore greater than the diameter of the guide section 52, so as to form, at the upper longitudinal end of the adjustment section 44, a transverse annular abutment surface which cooperates with a lower face of the guide ring 40 to immobilize the workpiece adjustment 42 in one of the two directions of the longitudinal direction relative to the main body 30. In the illustrated case, immobilization is ensured in the second direction of this direction by the presence, on the adjustment part

42, a flange 53 which delimits the upper end of the guide section 52, and which is therefore received longitudinally above the guide ring 40 to form a transverse annular abutment surface which cooperates with an upper face of the guide ring 40 for immobilizing the adjustment piece 42 in the second direction of the longitudinal direction relative to the main body 30.

In terms of manufacture, it is therefore understood that the assembly of the adjustment piece on the fixed body 30 can be carried out by winding the plate elements forming the guide rings 40 around the guide sections 52, over more than 180 °, preferably over 270 °. Advantageously, the guide rings 40 can be wound around the guide sections over nearly 360 ° which optionally allows each ring 40 to be closed, for example by a welding operation. However, care is taken to preserve the freedom in rotation of the adjustment part relative to the main body 30 about the hinge axis A1.

Advantageously, the adjustment piece 42 comprises, at a rear longitudinal end, a form of coupling 60 capable of cooperating with a tool for controlling the rotation of the adjustment piece. This form of coupling 60 has for example an imprint, recessed or in relief, making it possible to manipulate the adjusting piece in rotation using a key or a screwdriver.

For its part, the jacket 46 has a tubular body along the longitudinal axis of articulation A1. This tubular body is a body of revolution around the axis Al. As will be seen below, the adjustable stop surface 50 is formed by a transverse annular surface arranged at a front end of the tubular body of the jacket 46, in this case the upper end.

The jacket 46 is advantageously made of metal or of material having similar mechanical characteristics, in order to withstand the articulation forces between the door and the frame, in particular the weight of the door.

The tubular body of the jacket 46 is advantageously provided with a longitudinal slot 54 through which extends the main body of the male hinge 12, more precisely the transverse arm 34 of this main body. In the examples illustrated, the jacket 46 at least partially surrounds the support end 36 of the main body. For this, the tubular body of the jacket 46 delimits a cylindrical cavity, defined by an internal cylindrical surface of the body of the jacket, in which the internal thread 48 is formed. As can be seen in FIGS. 6 to 8 or 14 to 16 in particular, the one or two guide rings 40 are received inside this cavity insofar as they have an external diameter less than the diameter of the internal cylindrical surface of the jacket 46 in which the internal thread 48 is formed. In the first embodiment of Figs. 1 to 8, the slot 54 extends over the entire length of the jacket 46, and therefore opens at the two ends of the jacket in the direction of the axis A1. However, it could be provided that it opens out only at one end, for example the lower end, to have a continuity of material over the entire circumference of the adjustable stop surface 50, this being able to prove favorable to a better mechanical resistance of the adjustable stop surface 50. In the second embodiment of Figs. 9 to 16, the slot 54 extends over only part of the length of the jacket 46, and therefore opens into only one of the two longitudinal ends of the jacket, in this case into the transverse annular surface forming the abutment surface adjustable 50.

Because the transverse arm 34 extends through the longitudinal slot 54 of the jacket 46, the longitudinal edges of the slot 54 are capable of coming into contact with the transverse arm 34 to block the rotation of the jacket 46 around the axis Al. Preferably, this blocking takes place in both directions of rotation. Depending on the respective dimensions of the slot 54 and of the arm 34 along a circumference with respect to the axis A1, an angular play may however be provided between the jacket 46 and the main body 30. In this case, the slot 54 and the transverse arm 34 which extends through this slot form angular locking means, around the longitudinal axis of articulation, of the jacket 46 relative to the main body.

In the illustrated exemplary embodiments, the articulation rod 38 and the adjustment piece 42 are integral with one another, for example by being made in one piece. In this way, the articulation rod 38 is, in these embodiments, free to rotate about the axis of articulation relative to the main body 30, but fixed in translation along this axis relative to the main body 30 of the male hinge 12, like the adjustment piece 42. In this case, the articulation rod 38 extends at a longitudinal front end, here an upper end, of the adjustment piece 42, in the extension of a upper guide section 52, towards the front. In the example illustrated in Figs. 1 to 8, the articulation rod 38 has a diameter greater than the diameter of the adjacent guide section 52. In the second example illustrated in Figs. 9 to 16, the articulation rod 38 may have a diameter equal to the diameter of the guide section 52, from which it is separated by the flange 53.

However, as a variant, provision could be made for the articulation rod to be a separate part from the adjustment part 42. In this case, the articulation rod may be directly attached to the main body 30.

In the examples illustrated, at least one sleeve 56 is provided which comprises a tubular body 58, mounted to slide longitudinally on the articulation rod 48, and a radial collar 57, arranged at its rear end, here lower, which is in support longitudinally rearward directly or indirectly against the adjustable bearing surface 50 of the jacket 46. The inside diameter of the tubular body 58 of the sleeve 56 corresponds substantially to the outside diameter of the articulation rod 38, while its outside diameter corresponds substantially to the internal diameter of the cavity or eye 22 of the female hinge 14. In the first embodiment, a single sheath 56 is provided. In the second embodiment, a second sheath 56 ′ is provided, arranged head to tail at the opposite end of the cavity or eye 22 of the female hinge

14. In this second example, the two sleeves are open at their two ends.

In all cases, a support washer 62 can be provided interposed between the abutment surface 28 of the female hinge 14 and the adjustable abutment surface 50 of the male hinge 12.

Both the sleeve (s) 56, 56 ′ and the support washer 62 can advantageously be made of plastic material, for example polyamide, in particular to improve the friction conditions to avoid seizing and squeaking.

In the second embodiment, such a support washer 62 is interposed between the radial collar 57 of the sleeve 56 and the adjustable abutment surface 50 of the male hinge 12. In the second embodiment, the support washer 62 comprises a lug which engages in the longitudinal end of the slot 54 of the liner, in order to block any rotation of the support washer 62 relative to the liner 46.

The operation of the articulation system will now be more particularly described with reference to Figures 6 to 8 and Figures 14 to

16. In FIGS. 6 and 14, we see the guide ring or rings 40 of the main body 30 of the male hinge which are considered to be fixed, for example because they are fixed to a frame of the joinery. An upper face of the guide ring 40, for example the upper ring in the first embodiment, therefore defines a plane P perpendicular to the hinge axis A1, considered to be fixed. The guide section 52 of the adjustment piece 42 extends below the plane P and is extended longitudinally rearward, here downwards, by the adjustment section, possibly the second lower guide section 52 , and finally the coupling member 60. On the contrary, the articulation rod 38 which is here integral with the adjustment piece 42, extends forwardly above the fixed plane P. The jacket 46 is mounted on the adjustment piece 42 by cooperation of their respective threads 44, 48. This assembly is carried out by engaging the tubular body of the jacket 46 longitudinally around the support end 36 of the main body 30 until causing the two threads to engage. This engagement is permitted by engaging the transverse arm 34 through the slot 54 of the jacket 46. By rotation of the adjustment piece

42, the jacket 46 is caused to translate along the hinge axis A1 since the jacket 46 is locked in rotation about the axis Al relative to the main body 30 by the transverse arm 34. The jacket 46 is thus brought about in a service position, here a middle service position. Preferably, in this middle position, the entire length of the support end 36 of the main body 30 is received inside the jacket 46 in the longitudinal direction and is thus hidden. Advantageously, it is noted that, in this median position, the front longitudinal end of the jacket 46, which here forms the abutment surface 50, is arranged towards the front beyond the fixed plane P, and the rear longitudinal end of the jacket 46 is arranged rearwards beyond the coupling form 60 of the adjustment piece 42 so that the latter is also hidden, at least in side view.

On the other hand, the articulation rod 38 extends forwards, here upwards, beyond the front longitudinal end 50 of the sleeve 46. In this way, the eye 22 of the female hinge 14 can be engaged longitudinally from front to back, here from top to bottom, on the articulation rod 38 until the abutment surface 28 of the eye 22 of the female hinge 14 comes to bear, in this precise case indirectly with the interposition of the radial collar of the sleeve 56, or even in addition with the interposition of the support washer 62, against the abutment surface 50 of the jacket 46. The length of the articulation rod 38 and the position of the abutment surface 50 of the jacket 46 are chosen so as to ensure a sufficient length of engagement of the articulation rod 38 in the eye 22. It is noted that the tubular body of the sheath 56, which is received inside of the eye 22, is interposed radially, if possible without play or with very little play, between the eye 22 and the articulation rod 38. When it is not opening, as in the first embodiment of FIGS. 1 to 8, the tubular body 58 extends axially forwards beyond the front end of the articulation rod 38 to provide a capacity for displacement of the sleeve in both directions in the longitudinal direction relative to the articulation rod 38. In the second embodiment which comprises a sheath 56 opening at its two ends, the articulation rod 38 extends beyond the sheath and its upper end is received inside the second scabbard 56 '.

It is therefore understood that the position of the abutment surface 50 of the jacket 46 determines the relative position, in the direction of the hinge axis A1, of the female hinge 14 relative to the main body 30 of the male hinge 12.

However, as can be seen in FIG. 7 and in FIG. 15, by screwing the adjustment piece 42 in a first direction, the jacket 46 is caused to move relative to the main body 30 in the direction of the axis d hinge A1, so that the abutment surface 50 moves, in this case forwards to an advanced position, here upwards, causing an identical displacement of the female hinge 14 relative to the main body of the male hinge 12. We indeed see the relative displacement of the abutment surface 50 relative to the fixed plane P.

On the contrary, as can be seen in FIG. 8 and in FIG. 16, by screwing the adjusting piece 42 in the opposite direction, the jacket 46 is caused to move relative to the main body 30 so that the abutment surface 50 moves longitudinally in the other direction, in this case backwards to a retracted position, here downwards, causing an identical displacement of the female hinge 14 relative to the main body of the male hinge 12.

Thus, the abutment surface 50 of the jacket 46 indeed forms an adjustable abutment surface of the male hinge 12 which, by cooperating directly or indirectly with an abutment surface 28 of the female hinge 14, determines a relative service position, according to the longitudinal direction, between the male hinge 12 and the female hinge 14. Indeed, by comparing on the one hand Figures 6, 7 and 8, and on the other hand Figures 14, 15 and 16, we see that the body main 30, represented by the guide ring (s) 40, and the fixed plane P which they determine, is fixed, while the female hinge 14, in particular the tubular body 20, occupies three distinct positions offset one with respect to the other in the direction of the articulation axis A1. In the example illustrated, the system allows continuous adjustment of the relative position of the two hinges, that is to say in any position between two extreme positions .

Advantageously, the jacket 46 has an external diameter identical to the tubular body 20 of the female hinge 14, or to that of the cap 21, so as to have, in the service configuration of the articulation system, a continuity of the superimposed external surfaces according to the 'axis of articulation. As seen in Figures 6 to 8, or 14 to 16, the movements of the shirt 46 and the tubular body 20 of the female hinge 14 are done without creating unsightly play between the two.

Preferably, the jacket 46 has a length along the longitudinal axis A1 which is greater than the length of the support end 36 of the main body 30 increased by the length of its travel between a useful advanced position and a useful retracted position, that is to say forward and backward positions corresponding to maximum adjustment positions generally used. In this way, it is possible, as illustrated in FIGS. 7 and 8, and 14 and 16, to position the jacket 46 so that, for all the positions between these two useful extreme positions, the support end 36 of the main body 30 and the adjustment part remain hidden inside the jacket 46.

In addition, it could advantageously be provided that the male hinge 12 has a tightening screw 64 which is provided with an external thread which cooperates with the internal thread 48 of the liner 46. When the relative position of the two hinges is adjusted , the clamping screw 64 can be tightened in abutment longitudinally against a clamping face of the adjustment piece 42 to immobilize in rotation the adjustment piece 42 relative to the jacket 46, in the manner of a lock nut.

The invention is not limited to the examples described and shown since various modifications can be made thereto without departing from its scope.
