Description

1 2812904

  The invention relates to a hinge fitting for a door, window or the like, comprising a fixed part intended to be attached to the dormant frame of said door or window and comprising a fixing plate from which extends, substantially perpendicularly, to the minus a yoke for maintaining a hinge pin. The present invention will find its application in the field of building hardware and relates, more particularly, to

hinge fittings.

  We know, of course, many fittings

  articulation corresponding to the description above. They have

  for the function of ensuring the pivoting of a door or window opening relative to a dormant frame along a vertical and / or horizontal axis of rotation. Thus, they comprise a fixed part which is just attached to the sleeping frame, while the opening receives a movable part, also called blade, coming to cooperate with

  this fixed part through an axis of articulation.

  The mobile part comprises at least one socket engaged on this articulation axis, which is moreover held in the bore of at least one yoke associated with the fixed part. Note that this yoke of the fixed part extends, substantially perpendicularly, from a fixing plate comprising, most often, a plurality of openings for the passage of fixing screws in order to

the connection to the sleeping frame.

  In this regard, it should be noted that certain openings, by reason of their size and / or the nature of the glazing with which they are fitted, place great demands, by their weight, on such hinge fittings. Also, not only must the attachment to the sleeping frame be able to withstand such heavy opening, but, in addition, the hinge fitting itself must be

  adapted to withstand heavy loads.

  In particular, it is known to produce such hinge fittings by injection molding of a zinc-based alloy, such as Zamak (registered trademark). In fact, if such an alloy allows these hinge fittings to respond to the most common stresses, its resistance may prove

2 2812904

  insufficient for openings of a certain weight. Also, it is known to multiply the number of these articulation fittings connecting such an opening to the sleeping frame. Likewise, intermediate bearings are known which have the function of assisting these articulation fittings and taking charge of part of the stresses which they are normally brought to undergo alone, whether during the opening phases of the door. or window or at the time

  to close and compress the opening against the sleeping frame.

  Obviously such intermediate bearings or the use of additional articulation fittings represents an additional cost, not to mention that this results in a number of mounting operations.

for the carpenter.

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

  engage on this axis of articulation between two successive yokes.

  Obviously such a solution complicates the molding operations of this fixed part of the articulation fitting, molding which already proves to be complex due to the additional functionalities with which such a fixed part is usually still fitted. In particular, it is a question, through these functionalities, on the one hand, of facilitating to the fitter or to a user the mounting of an opening on its sleeping frame and, consequently, the cooperation between the mobile part of an articulation fitting with its fixed part and, on the other hand, to guarantee to such an operator that this assembly has been properly carried out and that there is no longer any risk that the articulation axis comes to disengage , unexpectedly,

  parts which it pivots with respect to each other.

  It is, for example, described in document FR-A-2,773,317 a device for holding a hinge pin where these features are found which make the molding operations of a fixed part somewhat more restrictive a fitting

3 2812904

  of articulation, in particular at the level of the yokes with which it is equipped. In fact, to address the problem of the resistance of these

  articulation fittings, it is known, in particular from the document FR-

  A-2,772,416, to overmold this fixed part of a hinge fitting on a metal insert, more particularly of steel. This comprises a wing extending in almost the entire width and length of the fixing plate, while at its ends it is folded back so as to define a tab on which is molded a yoke extending

  perpendicular to this mounting plate.

  If such hinge fittings have hitherto been satisfactory, it should be noted that the constraints applied to them are becoming greater. In particular in the case of joinery in profiles of relative rigidity, in particular in PVC, it is frequent to reinforce these profiles in their tubular part by a metallic reinforcement with which most of the time are engaged the various fittings which come to equip these joinery . However, a problem arises in the angles at which these metal reinforcements do not always extend, so that the hinge fittings which come to be fixed in these angles cannot cooperate, through all of their fixing with these metal reinforcements. Also, the weight applied to them by the sash tends to subject them to significant bending forces that these

  hinge fittings are not always able to support.

  The present invention aims to provide a solution to the aforementioned drawbacks. To this end, the invention relates to a hinge fitting for a door, window or the like, comprising a fixed part designed to be attached to the dormant frame of said door or window and comprising a fixing plate from which extends, substantially perpendicularly, at least one yoke for maintaining a hinge pin, characterized in that said fixing plate is defined by a metal blade comprising at least one lug defining said yoke and receiving,

4 2812904

  by overmolding, holding and / or safety means for

  immobilization of the articulation axis.

  Ultimately, the fixing plate corresponding to the fixed part of the hinge fitting according to the invention, is defined through a hard metal blade, in particular steel, of which, in a preferred embodiment , the ends are folded, substantially perpendicularly, so as to form yokes. At least one of the latter is associated, in particular by molding, with a certain number of functionalities, such as means of immobilization in axial translation of

  the hinge pin maintained and guided by such a yoke.

  Finally, the fixing plate of the fixed part being exclusively constituted by a blade made of hard metal, in particular steel, it gives the articulation fitting a substantially greater mechanical resistance. As for the overmolding operations, they only concern the screeds, so that their

execution is further facilitated.

  Other objects and advantages of the present invention

  will appear during the description which follows relating to

  to an embodiment given by way of indicative and nonlimiting example.

  Understanding this description will be facilitated by

  Referring to the attached drawing in which: - Figure 1 is a schematic representation in longitudinal section of the fixed part of a hinge fitting according to the invention; - Figure 2 is a schematic representation in longitudinal section 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 hinge pin in their unlocked position;

2812904

  - Figure 5 is a representation similar to Figure 4 said locking means being, here, illustrated in position

lock.

  As visible in the figures of the attached drawing, the present invention relates to the field of hinge fittings

for door, window or similar.

  Thus, such a hinge fitting 1 comprises a fixed part 2 which is just attached to the dormant frame of said door or window through a fixing plate 3. Significantly perpendicular to the latter extends at least

  a yoke 4, 4A provided for guiding a hinge pin 5.

  On the latter is able to be engaged a movable part (partially illustrated and in phantom in this figure 1) that

  one comes to report on the opening of this door or window.

  According to an embodiment more particularly shown in Figures 1 to 3 of the accompanying drawing, the mounting plate 3 comprises, substantially, at each of its ends 6, 7 a yoke 4, 4A, in which the ends of the

the axis of articulation 5.

  It will be understood, however, that the present invention is in no way limited to such a design, since this fixed part 2 of the articulation fitting 1 could receive only a single yoke 4, or even, on the contrary, intermediate yokes arranged

  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 of hard metal such as steel, from this blade 8 extending substantially perpendicularly, at least one tab 9, 9A of way to define

a yoke 4, 4A.

  Ultimately, from this blade 8 preferably extend as many legs 9, 9A as yokes 4, 4A

fitted to the fixed part 2.

  In the embodiment corresponding to the figures of the attached drawing, the blade 8 is folded at its ends so as to

  define these tabs 9, 9A corresponding to said clevis 4, 4A.

6 2812904

  Advantageously, in the internal angle 10, between the blade 8 and a tab 9, 9A, a reinforcing rib (not shown in the drawings) can be produced, for example obtained by a material return. In order to strengthen the mechanical strength of the hinge fitting 1, the blade 8 can, again, take a U-shaped section, in particular 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 to be attached to the surface against the frame, it can be bordered

by flanges 15, 16.

  Preferably and as already indicated above, these flanges, 16 extend substantially over the entire length of the blade 8, so that their ends 17, 18 coincide, substantially, with the tabs 9, 9A and that they can be imprisoned in a

  overmolding to which reference will now be made.

  In this regard, at least one of the legs 9, 9A, corresponding to the yokes 4, 4A, receives, by overmolding, holding means and / or

  19, 24 for immobilizing the hinge pin 5.

  Thus, through this intermediary, they can be associated with means for immobilizing in axial translation 19 the articulation axis 5. Very particularly, at the ends, 21 of this articulation axis 5 can be made a groove under shape of a peripheral groove 22, with chamfered edges, and in which is capable of engaging, elastically, a locking clip 23, in the form of an elastic metal wire, anchored at the level of said overmolding produced on legs 9 , 9A constituent

  said yokes 4, 4A, or even on each of them.

  In this regard, it will be observed that the present invention is in no way limited to such a design of these means of immobilization in axial translation of the articulation axis 5. In

  particular, it is already described in the document FR-A-

  2,773,377 such immobilization means, executed according to another embodiment, which one could quite envisage in combination with a hinge fitting with the characteristics

  in accordance with the present invention.

7 2812904

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

hinge fitting 1.

  Ultimately, the purpose of such locking means 24 is, on the one hand, to prevent the hinge pin 5 from being able to disengage involuntarily from the hinge fitting 1 and, on the other hand, to allow an operator to ensure, during assembly, that this axis of articulation has been fully engaged, at the level of the

mobile part and fixed part.

  Indeed, during this mounting and under the effect of a resistance possibly provided by the immobilizing means 19, the operator could be led to think that this axis of articulation 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 molding at least with the lower yoke 4, are defined by a locking tab 25 provided adapted to be pushed manually and / or elastically on the trajectory of the articulation axis 5,

  under the lower end 20 of the latter.

  As has just been specified, this locking tab 25 can be of an elastic nature so as 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, of said locking tab 25 in the unlocked position, visible in FIG. 4. In particular, such retaining means 26 may be in the form of a hook provided capable of cooperating with a hooking flange 27 that involves, at

  its end, the locking tab 25.

  However and according to another embodiment, said locking tab 25 can have a certain flexibility allowing it to be pushed back, by means of a tool such as a screwdriver, as the case may be in the unlocked position, as visible in the

8 2812904

  Figure 4, or in the locking position shown in the figure, the retaining means 26 being, in this case, unnecessary. Preferably, such blocking means 24 are associated with each of the tabs defining the end caps 4, 4A. In fact, it is advantageously given to the fixed part 2 of the articulation fitting 1 a symmetrical shape with respect to a transverse median plane P allowing the inversion of this fixed part

2 and, therefore, its reversibility.

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

is of increased rigidity.

  Obviously, at this blade 8 can be made a number of holes 28 for the passage of fasteners, such as screws. Similarly, it can receive, if necessary, indexing orifices 29 for its correct positioning in the injection mold for the design by overmolding, of said holding and / or safety means 19, 24. However, this indexing can , in this case, intervene in any other way. By way of example, the blade 8 can be grasped from its longitudinal sides 11, 12

  to ensure its positioning during molding.

  Although the invention has been described with reference to a particular embodiment, it is understood that it is in no way limited thereto and that it is possible to make various modifications to the forms, materials and combinations of these. various elements, without

  for this to move away from the framework and the spirit of the invention.
