As has been shown in FIG. 1a above, the universal hinge system that is the subject of the invention comprises at least a first point metal support plate 1 provided with a support tube 10 with drilling and tapping 10a. The first point support metal plate 1 is in fact a first anchor point of the hinge system and the hinge, as will be explained in more detail below. The support tube 10 and the first point support metal plate 1 form a unitary assembly that can be fixed on a mounting bracket S, such as an opening frame, a gate post or the like, as shown in FIG. In addition, as shown in FIG. 1a, the hinge system that is the subject of the invention comprises a hinge bearing part, bearing the reference 2, this part being pluggable onto the support tube 10. The hinge bearing part 2 is more commonly referred to as "ear" in the corresponding art. With the observation of Figure1a, it is understood that the gondant bearing part 2 carries a hinge 20 and has a longitudinal plane of symmetry, noted P, and that when the gonder bearing part 2 above is mounted on the support tube 10 , as shown in FIG. 1b, the assembly is also symmetrical with respect to the same longitudinal plane of symmetry. According to a remarkable aspect of the universal hinge system, subject of the invention, the gondant bearing part 2 and the hinge 20 are advantageously orientable in the direction of the longitudinal axis of symmetry of the hinge 20, constituting the axis of rotation of the sash around the aforesaid hinge, with respect to the first point 1 metal support plate. This makes it possible to use the universal hinge system that is the subject of the present invention in the majority of mounting situations, as will be described later in the description. Finally, the universal hinge system object of the invention is also remarkable in that it comprises a second point metal support plate 3, mounted laterally to the metal support plate first point 1 on the mounting bracket S by adjacent fixing. It is understood that the support plate second point 3 constitutes a second anchor point and improves the positioning, alignment and anchoring of the base of the hinge 20. It can be reserved preferentially for the heaviest opening or with greater inertia or for less robust mounting brackets S. In addition, a terminator 4 of hinge system overmoulded composite coating may be provided for clipping on the end of the metal support plate first point 1 or the metal support plate second point 3, as will be described below. after in the description. In FIG. 1a, it will be understood that the arrows represent the modular assembly of all the constituent elements of the universal hinge system, object of the present invention, to form the aforementioned universal hinge system mounted on the mounting bracket S, such than represented in FIG. Thus, in this figure 1b, the double arrow R substantially parallel to the longitudinal plane of symmetry P of the gondant bearing part 2, plane not shown in this figure 1b, represents a fine adjustment of the position of the hinge 20 relative to the mounting bracket S, which will be described later in the description, and the vertical double arrow crossed by a cross represents the total absence of vertical play of the assembly and mounted on the mounting bracket S, because of the fixing of the universal hinge system on the latter by means of fastening bolts B1 and B3 and fasteners P1 and P3 engaged in respective fastening openings 12 and 32. The arrows F1, and F3 in Figure 1b represent the effort of fixing the universal hinge system object of the invention on the mounting bracket S. It is thus understood that the positioning and alignment of all the components of the universal hinge system object of the invention s have achieved thanks to the specific shape of the first point support metal plate 1, the pluggable hinge bearing part 2 and the second point metal support plate 3 and that the maintenance of this positioning and alignment can be achieved by the intermediate bolts and aforementioned fasteners on the mounting bracket S. As will be observed further in Figures 1a and 1b, particularly advantageously, the metal plate support first point 1, the tube of support with drilling and tapping 10, the hinge bearing part 2 and the metal support plate second point 3 are provided with an overmoulded composite coating denoted 11, 21, 31 respectively. The aforementioned overmolded composite coating is a friction-resistant, anti-corrosion coating and may allow the execution of a surface treatment finish for example. Such a coating may be constituted by a polyamide or the like.

A more detailed description of the metal support plate first point 1 will now be given in connection with Figures 2a and 2b. Figure 2a shows the metal platinum first point support in its metal structure. The latter is constituted by a metal base 1a, of substantially rectangular shape, on which the support tube 10 with drilling and tapping 10a is welded with reinforcement. It comprises, as shown in the aforementioned figure, in addition to the attachment opening 12, fixing holes, positioning and centering on the mounting bracket S, these orifices being denoted lb, lc, Id, and the. These orifices are placed in the vicinity of the vertices of the substantially rectangular shape, in order to allow the assembly in position and in alignment of the metal support plate second point 3, or of the termination part 4, as will be described later in the description. The metal plate support first point 1 further comprises, on the metal base, lateral ribs, denoted 1f and 1g of fixing the overmoulded composite coating.

As shown in FIG. 2b, the overmolded composite coating 11 has, at the edges of the substantially rectangular base, opposite edge and edge adjacent to the support tube 10 with drilling and tapping, a recess 1h respectively 1 i for clipping either of the overmoulding of the metal platen second point 3 of the end piece 4 of the hinge system in overmolded composite coating. As shown in FIGS. 2b and 2c, these recesses are formed in the overmolded composite coating 11 of the first point 1 metal support plate, which is provided in the vicinity of the support tube side 10 and the opposite side thereof. a form of tenon 11a and 11b respectively. These forms of tenon are intended to cooperate with a form of mortise formed in the overmolded composite coating of the metal plate second point 3 respectively of the end piece 4, as will be described later in the description. The metal support plate second point 3 will now be described in connection with Figures 3a and 3b.

In FIG. 3a, there is shown a substantially rectangular metal base 30 constituting the metal support plate second point 3. The latter comprises, in addition to the central opening 32 for fixing and two end lugs each provided with a nipple 30a. and 30b. Referring to Figures 2a and 2b representative of the first point support metal plate, it is understood that the aforementioned pins 30a and 30b are intended to be plugged into one of the positioning and alignment holes 1b, 1c, Id and the equipping the metal plate support first point 1. The pins 30a and 30b formed on the metal base 30 confer a high resistance to the assembly. As shown in FIG. 3b, it is pointed out that the overmolded composite coating 31 of the second point 3 metal support plate makes it possible to keep said studs 30a and 30b clear and visible, which can then be plugged into the corresponding positioning and alignment holes. 1 b, 1 c or 1 d, 1 e respectively, depending on the mounting option finally chosen. Finally, with reference to FIG. 3b, in the overmoulded composite coating 31 there is a mortise shape 30d formed between the two studs 30a and 30b. The mortise 30d above is intended to cooperate with one of the tenons 11a or 11b of the overmolded composite coating 11 of the metal support plate first point 1. The side wall of the mortise 30d is advantageously provided with a lug 30c, come The lug 30c is intended to be fixed in one of the recesses 1h or 1l when the lugs 30a and 30b are inserted into the alignment orifices 1b and 1c or Id and the, during assembly of the components of the universal hinge system object of the invention as illustrated in Figures 1a and Ib. A more detailed description of the gondant bearing part 2 will now be given with reference to FIGS. 4a to 4e and 4f to 4i.

With reference to FIG. 4a, it is pointed out that the hinge bearing part 2 comprises at least one metal structure comprising a substantially square section base 21a and a central sleeve 22 placed in the center of the square section, as shown in FIG. 4b. The central sleeve 22 is directly insertable in the support tube 10 of the metal support plate first point 1.

Figures 4c and 4d show the constituent metal structure of the gondant bearing part 2 shown in Figure 4a and 4b provided with the corresponding overmoulded composite coating 21. Figure 4e shows a sectional view, along the longitudinal plane of symmetry P, the gondant bearing part 2, as shown in Figure 4c or 4d for example. FIG. 4e shows that the central sleeve 22 of the gondant bearing part 2 may advantageously consist of a countersunk head screw. Thus, the overmolded composite coating 11 of the support tube 10 of the first point 1 metal support plate is of square section, the square section base 21a of the gland bearing part 2 is plugged onto the support tube 10 provided with the overmolded composite coating. of square section 11 and the hinge bearing part 2 and the hinge 20 itself can be oriented at their installation by incremental angle of 90 °, with respect to the faces of the square section of the overmoulded composite coating 11.

This embodiment is given by way of non-limiting example. In particular, a different implementation consisting in providing a polygonal base 21a and an overmolded composite coating 11 of the support tube 10 of the first point metal platen 1 of similar section, also polygonal, does not go beyond the scope of the object of the present invention. In fact, this different mode of implementation makes it possible to orient the gonder-bearing piece and the hinge by an angle increment of less than 90 °, for the purpose, for example, of constituting a hinge with oblique opening, with respect to the vertical and / or horizontal. As will be observed further in Figure 4e, the constituent metal structure of the gondant bearing part 2 may advantageously be formed by a first metal part 23 having an opening 23a in its center, a second metal part 24 having a chamfered opening for receiving the head of the countersunk screw 22 and a metal tube 25 square or polygonal section as mentioned above. The parts 23, 24 and 25 are shown in Figure 4f, 4g and 4h, Figure 4i showing a metal axis for forming the hinge 20 for example.

The metal structure of the gondant bearing part 2 thus consists of the metal tube 25 of square section welded to the metal parts 23, 24 in the form of a plate and the cylindrical metal axis is welded on the assembly to form the hinge 20. The single countersunk screw 22 is trapped freely between the plates 23 and 24 and acts as a set screw. This embodiment allows the execution of a precise and resistant adjustment system. It is understood, in particular, that the countersunk screw 22 is thus screwed through the part 24, which is fixed to the square-section tube-shaped part 25 for fastening the assembly by means of the countersunk screw 22 screwed into the tapping 10a of the support 10. This embodiment allows a setting R of the spacing of the hinge 20 relative to the metal platen support first point 1 and the support plate second point 3 indicated above in reference to FIG. For this purpose, an adjustment key can be inserted into the opening 23a to control the tightening of the countersunk screw 22. A more detailed description of the termination part 4 is now given in connection with FIG. Terminator 4 is preferably made of composite material only. This termination piece is intended to complete the assembly of the universal hinge system object of the invention, as shown in Figure la or lb, and to cap one of the ends of the metal support plate first point 1 according to the assembly finally retained. For this purpose, the end piece 4 comprises, as shown in FIG. 5, two studs of material 4a and 4b, which are placed at the opposite ends of the end piece 4. It will be understood that the abovementioned pads are intended for they are plugged into the positioning and alignment holes 1b and 1c or 1d and the one of the first point 1 support plate. The central part of the end piece 4 is provided with a mortise shape 40a intended to cooperate with the one of the tenon forms 11a or 11b presented by the overmolded composite coating 11 of the first point support metal plate 1. The side wall of the mortise shape 40a comprises in the center of the latter a pin 4c, which is intended to be inserted by clipping in one of recesses lh or li formed in the form of post 11a or 11b abovementioned. The method of implementation as described of the universal hinge system object of the invention is particularly advantageous, insofar as, due to the modularity of the latter, different assembly configurations can be envisaged. These configurations are illustrated in FIGS. 6a to 6f. In general, it is indicated that the assembly of the gondant bearing part 2 and the hinge 20 can be executed either in the end position of a first point metal support plate 1 and the adjacent end piece 4, or in central portion of a first point metal support plate 1 and a second adjacent point support metal plate, in parallel or orthogonal direction of the hinge vis-à-vis the alignment of the plate and the terminal or plates adjacent. The various mounting modes are shown in Figures 6a and 6b where the gondant bearing part 2 and the hinge 20 are mounted in the central part of the first point 1 metal support part and the second point 3 metal support part, the hinge 20 being oriented orthogonally respectively parallel to the alignment of the first point metal support member and the second point metal support member 3, in FIGS. 6c and 6d where the hinge bearing part 2 and the hinge 20 are mounted in the end position a metal plate first point 1 and the second point metal support piece 3, the hinge 20 being oriented orthogonally respectively parallel to the alignment of the metal support part first point 1 and the metal support part second point 3, on FIGS. 6e and 6f in which the hinge bearing part 2 and the hinge 20 are mounted in the end position of the support metal plate. first point 1, the hinge 20 being oriented parallel respectively orthogonal to the alignment of the metal support part first point 1 and the end piece 4.
