DETAILED DESCRIPTION OF EMBODIMENTS

The figure 1a represents in perspective view a hinge 100 according to a non-limiting embodiment of the invention. The hinge 100 is intended to equip any frame comprising at least one fixed frame 300, shown in FIG. figure 8 , and a mobile opening 200, shown on the figure 7 , pivotable vis-à-vis the frame, such as the usual doorframes doors, windows or the like.

The hinge 100, according to the illustrated embodiment, comprises an upper insert 10 for fixing the hinge to the frame, a base 20 which cooperates with the upper insert to form the fixed part of the hinge, a plug 30 concealing the base, a brush 40, an axis 50, a lower insert 60 in which said axis is secured, a locking insert 70, a retaining screw 80 supporting the axis and the inserts, lower and locking, various screws for assembling the elements mentioned and an inclined screw 96 allowing adjustment of the 'plumb of the opening.

The various elements of the joint are joined elements and can be made in different shapes and sizes and in different materials provided that the desired functionality of the joint is preserved.

In the remainder of the description, the terms "up", "down", "forward", "backward", "superior", "lower" and the terms and expressions that may be associated with them or derived therefrom will be understood, unless otherwise stated or proven otherwise, as having the meaning that an observer of a frame equipped with the hinge 100 shown in figure 1a . Given the axis system represented on the figure 1a , the front and the top are located respectively according to the X increasing abscissa and the Z increasing ribs.

The upper insert 10, shown in perspective in the exploded view of the figure 1b and in view from below on the figure 4 , is a profile having a slightly trapezoidal U-shaped profile defining an inner recess 11. The upper insert 10 has a straight section 12 at one end and an inclined section 13 at a second end opposite said first end, the inclined section being then parallel to a cutting plane of a profile of the frame in which said upper insert is fixed. The inclination of the inclined section 13 is for example 45 ° with respect to a longitudinal axis of the upper insert 10.

This condition is however not mandatory and the upper insert may have a cross section at each of its ends.

The upper insert 10 allows the attachment of the hinge 100 to the frame and is in this an interface between the frame and the rest of the joint. Thus, the upper insert 10 is provided with a direct fixing hole 14 allowing a suitable screw, not shown, to directly clamp said upper insert against an upper cross member of the frame, intermediate fixing holes 15, allowing adapted screws through the base 20 to clamp said base against the upper insert and said upper insert against the upper cross member of the frame, and an inclined hole 16 to adjust the plumb of the opening by clamping a adapted screw.

In the following, the profile of an amount of the door and the profile of a cross member of the frame of a frame will respectively be designated by the amount of the opening and through the frame, which represent the parts of the frame to which said profiles are secured.

Preferably the inclined hole 16 for adjusting the plumb has an inclination with respect to the longitudinal axis of the upper insert 10 substantially equal to the inclination of the inclined section 13 with respect to said longitudinal axis, for example 45 °, thus limiting the effort required to adjust the plumb.

Furthermore, each of the holes 14, 15 and 16 of the upper insert 10 is opening, when the upper insert is positioned at the upper cross member of the frame, on a similar hole in said upper rail.

In the embodiment illustrated in figure 4 , the direct fixing hole 14 is a smooth hole 6 mm in diameter for example. The intermediate fixing holes 15 are tapped holes having a metric thread M5, that is to say with a pitch of 0.8 mm and a drilling diameter of 4.2 mm. In the following, the metric threads being standardized and known to those skilled in the art, the characteristics of the metric threads used will not be explained.

In the same embodiment, the inclined hole 16 for adjusting the plumb is a tapped hole and has a metric thread M4.

The upper insert 10 is fixed to the base 20 via fixing screws 95 and a set screw 96 adapted, solidarisant said base of said upper insert, itself integral with the upper cross member of the frame, thus forming the fixed assembly of the hinge 100. The adjusting screw 96 further allows adjustment of the plumb of the opening.

The base 20, shown in perspective on the figures 1b and 2 , mainly comprises a ring 21 in which is made a bore 211 and a chamber not shown in the figures. Indeed, the base 20 constitutes the female part of the hinge 100 and is integral with the frame, the male part being formed by the assembly upstream of the base, with the axis 50 projecting, and integral with the opening, unlike the joints of known doors in which the male pin is fixed to the frame while the female part is fixed to opening thus causing a significant congestion of the joint which is then visible and imposing on the frame.

The base 20, according to the illustrated embodiment, has oval holes 25 opening, vis-à-vis the right intermediate fixing holes 15 of the upper insert 10, in which are arranged the fixing screws 95 threading M5 metric. The base 20 further comprises a specific opening hole 26 whose machining is adapted to receive the metric thread adjusting screw 96 M4 in an inclined position, said specific hole being opposite the inclined hole 16 adjusting the plumb in the upper insert 10.

As illustrated on the figure 8 , the base 20 is slidably mounted in a groove 320 of the upper cross member 310 of the frame 300 of the frame, the fastening screws are then used to immobilize said base tale said upper cross.

Indeed, the oval holes 25 of the base 20 allow said base to slide in the groove 320 of the upper cross member 310 of the frame 300 when the fixing screws 95 engaged in said oval holes are unscrewed. This sliding of the base 20 then allows adjustment of the plumb of the opening with the aid of the adjustment screw 96. The tightening of the fixing screws 95 then makes it possible to freeze the position of the base 20 relative to to the upper insert 10 and thus with respect to the frame of the frame.

Each fixing screw 95 passes through an ovalized hole 25 of the base 20 until the head of said right screw abuts in a countersink 251 of said ovalized hole, the threaded rod of said straight screw extending outside the base 20 is screwed into the intermediate fixing hole 15 vis-à-vis said ovalized hole in the upper insert 10, and in a fixing hole of the upper cross member of the frame.

In the same way, the adjustment screw 96 cooperates with the specific hole 26 of the base 20, the inclined adjustment hole of the plumb 16 of the upper insert, and a suitable hole in the upper cross member of the frame.

It is thus obtained a robust tightening of the fixed assembly of the hinge 100, that is to say the upper insert 10 and the base 20, against the frame of the frame, thus forming the female part of said hinge, the male part, fixed as for it to an amount 210 of the opening 200 of the frame, is described in the following.

The male part of the hinge 100 mainly comprises the axis 50, the stopper 30 concealing said axis at the top of the jamb of the opening, the brush 40, the lower insert 60, the locking insert 70, the screw restraint 80, and a set of screws adapted.

The axis 50, represented integrally with the figure 1b , is a solid cylindrical rod of circular cross section chamfered at both ends. The axis 50 is made of a material having a sufficient mechanical strength and rigidity to withstand a significant load of the frame and heavy use of said frame, such as a metal alloy based on nickel and chromium, preferably an alloy X8CrNiS18-09 according to the European standard EN 10088.

In the illustrated embodiment, the axis 50 has a length of 80 mm.

The axis 50 engages in the lower insert 60 by an upper face of said lower insert as shown in FIG. figure 1b , said axis being mounted tightly in the lower insert to be secured to said lower insert.

The lower insert 60, shown at figure 5 , is a parallelepiped block having a longitudinal bore 61 opening in which is formed a recess 611 opening on the upper face of said lower insert. The axis 50 is engaged in the recess 611 to a shoulder 612, resulting from the diameter variation of the bore 61, on which said axis abuts. Thus, the axis 50 has an overshoot on a useful length, corresponding substantially to the difference between the length of said axis and a depth of the recess 611, outside the lower insert 60. This overshoot allows the axis 50 of s engage in the plug 30 and the base 20.

In the illustrated embodiment, the useful length of the projection of the axis 50 relative to the upper face of the lower insert 60 is 29 mm for example.

The lower insert 60 further includes smooth holes 65 and a threaded through hole 64 for assembling said lower insert with the locking insert 70.

The plug 30, shown at figure 3 , is a structure having a shape and dimensions adapted to hide a major part of the base 20 and the axis 50 while integrating at best the visual aspect of the frame at the frame of the opening 200 and the upper cross member of the frame. The plug 30 has visible faces, once the hinge 100 mounted on the frame, represented hatched on the figures 1b and 3 and for which a paint type coating is required. A paint can for example be applied to these faces by a lacquering type process.

The plug 30, in addition to its aesthetic function, has a hole 31 opening allowing the passage of the axis 50, said axis then joining the base 20, and a threaded hole 35 accommodating the retaining screw 80 as will be described later.

The hinge 100, according to the illustrated embodiment, comprises a robust sliding ring 51 having advantageous tribological performance, allowing an improved fit of the axis 50 in the ring 21 of the base 20.

The ring 51 allows an axial and radial retention of the axis 50 in the recess of the bore 211, and is designed for maintenance-free application and dry operation without lubricant.

Preferably, the ring 51 is chosen from a range of rings marketed under the trademark Permaglide, and known for their low tendency to glue-slip phenomenon, low wear, good resistance to chemical attack, low coefficient of friction and inability to weld with metals.

The brush 40, shown on the Figure 1a and 1b , has an adhesion edge 41 allowing a bonding of said brush on an upper side of the cap 30 as shown in FIG. figure 1a . The brush 40 thus placed conceals the base 20 between the plug 30 and the upper cross member of the frame, see figure 7 .

The brush 40 ensures the continuity of seals at the upper cross member of the frame and at the upper end of the amount of the opening.

The locking insert 70, shown on the figure 6 , is a profile having a geometric shape which generally takes the form of the upper insert 10. The locking insert further comprises a longitudinal hole 71 smooth and open, and threaded transverse holes 75.

In an exemplary embodiment, the retaining screw 80 has a smooth portion 81 which extends from the screw head over a length less than the total length of the retaining screw, and a threaded portion 85 which extends said portion. smooth to the free end of the retaining screw.

The retaining screw 80 engages in the longitudinal hole 71 of the locking insert 70 via its smooth part 81, and in the tapped hole 35 of the plug 30 by its threaded portion 85.

The retaining screw 80 makes it possible to hold the locking insert 70, the lower insert 60 and the axis 50 fixed in the amount of the sash and thus constitutes an abutment for the male part of the hinge 100.

Fixing the male part of the hinge 100 in the amount 210 of the opening 200 is made by screws which tighten in order the lower insert 60 and the locking insert 70 against a profile of said amount , in the manner of clamping the base 20 and the upper insert 10 against a section of the cross member of the frame described above.

Indeed, screws 95 of metric thread M5 cooperate with the smooth holes 65 of the lower insert 60, the tapped holes 75 of the locking insert 70 and adapted holes, also tapped, in the amount 210 of the opening .

A safety screw 94 of metric thread M4 makes it possible for it to avoid any translation of the inserts, lower and locking, and the axis in a longitudinal direction of the amount of the opening when the distal end of said screw safety comes flush an outer face 220 of the amount 210 of the opening, as shown in the figure 7 said security screw then abuts on a lower edge of a hole 230 of the post 210, said hole further allowing access to said security screw.
