The hinge plate has a metal panel with a bent foot extending perpendicular to it to define a frame around which the flange is mould ed.

Description

The invention relates to a hinge fitting for a door, window or the like, comprising a fixed part provided for be attached to the frame of said door or window and comprising a fixing plate from which extends, substantially perpendicularly, at least one yoke for the maintenance of a articulation axis.

The present invention will find its application in the field of building hardware and related plus in particular, to hinge fittings.

We know, of course, many fittings articulation corresponding to the description above. They have the function of ensuring the pivoting of a door leaf or window in relation to a sleeping frame along an axis of vertical and / or horizontal rotation. Thus, they include a fixed part that has just been brought to the frame, while the opening receives a mobile part, also called blade, coming to cooperate with this fixed part through an axis hinge.

The mobile part comprises at least one socket engaged on this articulation axis, which is also maintained in the bore of at least one yoke associated with the fixed part. AT note that this cap of the fixed part extends, substantially perpendicularly, from a fixing plate comprising, more often than not, a plurality of openings for the passage of fixing screw for connection to the frame.

In this regard, it should be noted that some openings, in because of their size and / or the nature of the glazing they are equipped with heavy demands due to their weight such hinge fittings. Also, not only fixing the frame must be able to withstand such opening heavy but, in addition, the hinge fitting itself must be adapted to withstand heavy loads.

In particular, it is known to make such joint fittings by injection molding of an alloy based on zinc, such as Zamak (registered trademark). In fact, if a such an alloy allows these articulation fittings to respond to most common stresses, its resistance may be insufficient for openings of a certain weight. Also, it is known to multiply the number of these hinge fittings connecting such an opening to the sleeping frame. Likewise we know intermediate bearings whose function is to assist these hinge fittings and take over some of the constraints that they are normally brought to undergo alone, whether during the door opening phases or window or when closing and compressing the opening against the sleeping frame.

Obviously such intermediate bearings or the use of additional hinge fittings represent an additional cost, not to mention that this results in a number of assembly operations for the carpenter.

It is also known to increase the size of this fixed part a hinge fitting and, in particular, to spare, at level of the mounting plate and between two yokes end, now on either side the axis of articulation, intermediate screeds systematically crossed by this axis. In this case, the mobile part includes a plurality of sockets each coming to engage on this axis of articulation between two successive yokes.

Obviously such a solution complicates the operations of molding of this fixed part of the articulation fitting, molding which is already complex due to additional functionality which is still fitted usually such a fixed part. In particular, it is, through these features, on the one hand, to facilitate fitter or a user mounting a sash on its frame dormant and, therefore, cooperation between the party mobile of a hinge fitting with its fixed part and, on the other hand, to guarantee to such an operator that this assembly has has been properly executed and there is no longer any risk that the articulation axis unexpectedly emerges from the parts which it pivots relative to each other.

It is, for example, described in document FR-A-2,773,317 a device for holding a hinge pin where we find these features which make it somewhat more restrictive molding operations for a fixed part of a fitting of articulation, in particular at the level of the yokes of which it is equipped.

In fact, to address the problem of the resistance of these hinge fittings, it is known, in particular by the document FR-A-2.772.416, to overmold this fixed part of a hinge fitting on a metal insert, plus particularly steel. This has a wing extending along the length of the mounting plate, while at its ends it is folded so as to define a tab on which is overmolded a screed coming to extend perpendicular to this mounting plate. Because of this overmolding the section of this insert is necessarily limited.

If such hinge fittings have hitherto provided satisfaction, it should be noted that the constraints which their applied are becoming more and more important. In particularly in the case of joinery with stiffness profiles relative, especially in PVC, it is common to reinforce these profiled in their tubular part by a metallic reinforcement with whom most of the time are engaged fittings that these carpentry equips. However a problem arises in the angles at which not always extend these metal reinforcements, so that the hinge fittings which are fixed in these angles cannot cooperate, through all of their fasteners with these metal reinforcements. Also, the weight applied to them by the sash tends to subject to significant bending forces that these fittings are not always able to bear.

The present invention aims to provide a solution to aforementioned drawbacks. To this end, the invention relates to a hinge fitting for door, window or similar, comprising a fixed part intended to be attached to the sleeping frame of said door or window and comprising a mounting plate from which extends, substantially perpendicularly, at least one yoke for the maintenance of a articulation axis, characterized in that said plate fixing is defined by a metal blade comprising at at least one leg defining said yoke and receiving, by overmolding, holding and / or safety means for immobilization of the articulation axis.

Ultimately, the mounting plate corresponding to the fixed part of the hinge fitting according to the invention, is defined through a hard metal blade, in particular in steel, of which, in a preferred embodiment, the ends are folded, substantially perpendicularly, of so as to form screeds. At least one of these are associated, in particular by overmolding, a certain number functionalities, such as means of immobilization in axial translation of the articulation axis maintained and guided by such a screed.

Finally, the fixing plate of the fixed part being exclusively constituted by a hard metal blade, in particular in steel, it gives the hinge fitting resistance substantially more mechanical. As to overmolding operations, they only concern the screeds, so that their execution is further facilitated.

Other objects and advantages of the present invention will become apparent during the following description relating to a example of realization.

Understanding this description will be facilitated by referring to the attached drawing in which:

Figure 1 is a schematic representation in section longitudinal of the fixed part of a hinge fitting according to the invention.

Figure 2 is a schematic representation in section longitudinal of the blade defining the fixing plate of this fixed part.

Figure 3 is a plan view of this blade illustrated in figure 2.

Figure 4 is a bottom view of Figure 1 showing locking means in axial translation of the axis hinge in their unlocked position.

Figure 5 is a representation similar to Figure 4 said blocking means being, here, illustrated in the position of locking.

As visible in the figures of the attached drawing, this invention relates to the field of hinge fittings for door, window or similar.

Thus, such a hinge fitting 1 comprises a part fixed 2 which has just been brought to the frame of said door or window through a mounting plate 3. Significantly perpendicular to the latter extends to minus a yoke 4, 4A provided for guiding an axis of articulation 5. On the latter is able to be engaged a mobile part (partially illustrated and in dashed lines on this figure 1) that we just relate to the opening of this door or window.

According to an example of embodiment more particularly represented in Figures 1 to 3 of the attached drawing, the plate of attachment 3 comprises, substantially, at each of its ends 6, 7 a yoke 4, 4A, in which the ends of the hinge pin 5.

It will be understood, however, that the present invention is not in no way limited to such a conception, since this part fixed 2 of the hinge fitting 1 could not receive only one yoke 4, or even, on the contrary, yokes intermediaries disposed between such end caps 4, 4A.

In fact, according to the invention, said fixing plate 3 is defined by a metal blade 8, more particularly in hard metal such as steel, from this blade 8 extending substantially perpendicularly, at least one tab 9, 9A of so as to define a yoke 4, 4A.

Ultimately, from this blade 8 extend preferably as many legs 9, 9A as yokes 4, 4A fitted to the fixed part 2.

In the embodiment corresponding to the figures of the drawing attached, the blade 8 is folded at its ends so as to define these tabs 9, 9A corresponding to said clevis 4, 4A.

Advantageously, in the internal angle 10, between the blade 8 and a tab 9, 9A, a reinforcing rib can be produced (not shown in the drawings), for example obtained by a reference matter.

In order to strengthen the mechanical strength of the fitting of articulation 1, the blade 8 can, again, borrow a section U-shaped, especially in its portion extending between the legs 9, 9A. Thus, on its longitudinal sides 11, 12 and on its front face 13, opposite the rear face 14 intended for be attached as a wall against the frame, it can be bordered by flanges 15, 16.

Preferably and as already indicated above, these edges 15, 16 extend substantially over the entire length of the blade 8, so that their ends 17, 18 coincide, substantially, with the legs 9, 9A and that they can be trapped in a molding to which reference will be made now.

In this regard, at least one of the legs 9, 9A, corresponding to the yokes 4, 4A, receives, by overmolding, holding means and / or safety 19, 24 for immobilizing the axis hinge 5.

Thus, through this intermediary, they can be associated with means of immobilization in axial translation 19 of the axis 5. In particular, at the level of ends 20, 21 of this hinge pin 5 can be made a groove in the form of a peripheral groove 22, at the edges chamfered, and in which is able to engage, elastically, a locking clip 23, in the form of a wire elastic metal, anchored at said overmolding on legs 9, 9A constituting said yokes 4, 4A, or even on each of them.

In this regard, it will be observed that the present invention is not in no way limited to such a conception of these means immobilization in axial translation of the articulation axis 5. In particular, it is already described in the document FR-A-2,773,377 such means of immobilization, executed according to another embodiment, which one could quite consider in combination with a hinge fitting to characteristics in accordance with the present invention.

Likewise, a tab 9, 9A can be provided by overmolding of additional locking means 24, with manual control, having, here again, the function of preventing any axial displacement of the hinge pin 5, once the door opening or window permanently mounted on its sleeping frame and, therefore, after having brought in cooperation with the fixed part 2 the part of the hinge fitting 1.

Ultimately, such blocking means 24 are intended, on the one hand, to avoid that the axis of articulation 5 can unintentionally disengage from the hinge fitting 1 and, secondly, to allow an operator to ensure, during of the assembly, that this axis of articulation has been engaged, in all, at the mobile part and the fixed part.

Indeed, during this mounting and under the effect of resistance possibly provided by the immobilization means 19, the operator could be led to think that this axis hinge 5 is in the fully engaged position, while it is not.

According to the embodiment more particularly visible in Figures 4 and 5, said locking means 24, associated by overmolding at least at the lower yoke 4, are defined by a locking tab 25 provided capable of being pushed back manually and / or elastically on the axis trajectory articulation 5, under the lower end 20 of the latter.

As has just been specified, this locking tab 25 can be elastic in nature to be pushed back under this end 20 of the hinge pin 5. In this case, said locking means 24 also include retaining means 26, under elastic stress, said locking tab 25 in unlocked position, visible in figure 4. In particular, such retaining means 26 may arise in the form of a hook provided capable of cooperating with a flange hooking 27 which comprises, at its end, the tongue of blocking 25.

However and according to another embodiment, said locking tab 25 may have some flexibility allowing to repel it, by means of a tool such as a screwdriver, as appropriate in the unlocked position, such as visible in Figure 4, or in the locked position shown in FIG. 5, the retaining means 26 being, in this case, unnecessary.

Preferably, such blocking means 24 are associated with each of the legs defining the end caps 4, 4A. In fact, it is advantageously given to the fixed part 2 of the hinge fitting 1 a symmetrical shape with respect to a transverse median plane P authorizing the reversal of this fixed part 2 and, therefore, its reversibility.

Finally, it will be observed that due to the increased resistance conferred on the fixed part 2 of a hinge fitting 1, a fixing plate 3 designed exclusively by a blade in hard metal, in particular steel, the means for holding and / or safety 19, 24 for immobilizing the hinge pin 5 can be designed by overmolding on the legs 9, 9A in one material not necessarily metallic, but also synthetic. Indeed, almost all the efforts inflicted by the hinge pin 5 on the yokes 4, 4A is directly passed on by said legs 9, 9A, on this blade 8 corresponding to the fixing plate 3 which is rigid increased.

Obviously, at the level of this blade 8 can be made a certain number of orifices 28 for the passage of fixing, such as screws. Likewise, it can receive, if necessary, indexing holes 29 for its good positioning in the injection mold for design by overmolding, of said holding and / or safety means 19, 24. However, this indexing can, in this case, intervene another way. For example, the blade 8 can be grasped from its longitudinal sides 11, 12 to ensure its positioning during molding.
