Description

Joint hardware for door, window or Similary.

The invention relates to a hardware of joint for door, window or similar, comprising a fixed part intended to be inserted against the frame of said door or window and that involves a fixing plate from the which extends, substantially perpendicularly, at least one fork to maintain a joint shaft.

The present invention will find its application in the scope of the construction hardware store and refers, in particular, to articulation fittings.

Obviously, numerous ironworks are already known joint corresponding to the description above. its function is to ensure the rotation of a door leaf or window relative to a frame along a vertical rotation axis and / or horizontal. Thus, they involve a fixed part that is inserted against the frame, while the blade receives a moving part, also called foil, which cooperates with this fixed part through An axis of articulation.

The mobile part has at least one socket inserted on this axis of articulation, which is, on the other side, kept in the smoothing of at least one associated fork With the fixed part. It will be noted that this fork of the fixed part is extends substantially perpendicularly from a plate of fixation that most often involves a plurality of openings for the passage of fixing screws, with a view to the frame connection.

For this purpose, it should be noted that some sheets, due to its size and / or the nature of the glazing of the which are planned, highly request, by weight, such articulation fittings Therefore, not only fixing to frame must be able to withstand such heavy leaves, but, in addition, the articulation hardware itself must be adapted to Resist important solicitations.

In particular, it is known to perform such articulation fittings by injection molding of a zinc based alloy, such as Zamak (registered trademark). From In fact, although such an alloy allows these hardware articulation resist the most usual solicitations, your resistance may be insufficient for sheets of a certain weight Therefore, it is known to multiply the number of these articulation fittings that connect such a blade with the frame. Also, intermediate bearings are known whose function is to assist these articulation fittings and receive part of the tensions that they normally must withstand alone, both during the opening phases of the door or window, as in the time to close and compress the sheet against the frame.

Obviously, such intermediate bearings or the use of additional articulation hardware represents a cost additional, in addition to that resulting in a number of operations of additional mounting for the carpenter.

It is also known to increase the size of this fixed part of a joint hardware and, in particular, arrange, at the level of the fixing plate and between two forks end that keep the joint axis on both sides, intermediate forks systematically crossed by this axis. In this case, the mobile part has a plurality of bushings. that are inserted, each one, on this axis of articulation between two successive forks.

Obviously, such a solution complicates operations of molding of this fixed part of the articulation hardware, molding that is already complex due to functionalities additional of which is also usually provided fixed part. In particular, it is, through these functionalities, on the one hand, of facilitating for an installer or a user mounting a sheet on its frame and, consequently, cooperation between the mobile part of an articulation hardware and its fixed part and, on the other hand, to guarantee such operator that this assembly has been carried out in an appropriate way and that no longer exists no risk of the joint axis coming out, unexpectedly, of the pieces whose rotation one respects another ensures.

It is described, for example, in the document FR-A-2,773,377, which publishes the characteristics mentioned in the preamble of claim 1, a maintenance device of a joint axis in which are these functionalities that do something else constraining the molding operations of a fixed part of an articulation fitting, particularly at the level of the forks of which it is provided.

In fact, to solve the problem of resistance of these articulation fittings, it is known, in particular through the document FR-A-2,772,416, mold this part fixed of an articulation hardware on a metallic insert, in particular steel. The latter involves a wing that extends over the length of the fixing plate, while in its ends is folded so that it defines a leg on which a fork is molded that extends perpendicularly to This fixing plate. Due to this molding, the section of This insert is necessarily limited.

While such articulation fittings have been satisfactory until then, it should be noted that the pressures that are applied to them are growing. In particular, in the case of carpentry profiles of a relative stiffness, in particular of PVC, it happens frequently that these are reinforced profiles in its tubular part by means of a metallic reinforcement with the which gear in most cases the different hardware of which are provided these carpentry. However, it arises  a problem in the corners at the level of which not always extend these metal reinforcements, so that the hardware of joint that are fixed in these corners cannot cooperate, to through all its fixing organs, with these reinforcements metallic Therefore, the weight that is applied to them by the sheet tends to subject them to significant bending efforts that do not They are always able to withstand these articulation fittings.

The present invention aims to propose a solution for the above mentioned inconveniences. To that end, The invention relates to a door articulation fitting, window or the like, comprising a fixed part intended to be inserted against the frame of said door or window and that comprises a fixing plate defined by a metal sheet which involves at least one leg that extends perpendicularly to this sheet and that defines a fork for the maintenance of a articulation shaft, receiving this leg, by molding, maintenance and / or safety means for the immobilization of the articulation axis, characterized in that said sheet adopts a U-shaped section that extends between legs on its sides and its front face, opposite the back face intended to be inserted in apply against the frame, being said sheet fenced with flanges.

After all, the fixing plate corresponding to the fixed part of the articulation fitting according to the invention is defined by a sheet of hard metal, in particular steel, whose ends are, in one embodiment preferred, bent, substantially perpendicularly, so that forms hairpins. With at least one of the latter are associated, in particular by molding, a certain number of functionalities, such as immobilization means in axial translation of the articulation axis maintained and guided by such fork.

Finally, since the fixing plate of the fixed part consists exclusively of a sheet of hard metal, in particular steel, gives the articulation hardware a substantially higher mechanical strength. As for the molding operations, only refer to the forks, of so that its execution is easier.

Other objectives and advantages of this invention will appear during the description that follows and that refers to an embodiment example.

The understanding of this description will be provided with reference to the attached drawing, in which:

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

Figure 2 is a schematic representation and in longitudinal section of the sheet that defines the plate of fixing of this fixed part.

Figure 3 is a plan representation of this sheet illustrated in figure 2.

Figure 4 is a bottom view of the figure 1, which represents locking means in axial translation of the axis of joint in its unlocked position.

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

As you can see in the figures in the drawing attached, the present invention concerns the field of hardware of articulation for door, window or similar.

Thus, such articulation hardware 1 involves a fixed part 2 that is inserted against the frame of said door or window through a fixing plate 3. Substantially perpendicular to the latter extends at least one fork 4, 4A intended for guiding an articulation shaft 5. About the latter is able to be inserted a moving part (illustrated partially and in mixed line in this figure 1) which is inserted against the leaf of this door or window.

According to an embodiment shown in particular in figures 1 to 3 of the attached drawing, the plate of fixing 3 involves, substantially, at each of its ends 6, 7, a fork 4, 4A, in which the ends are maintained of the articulation axis 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 articulation hardware 1 could receive intermediate forks arranged between such end forks 4, 4A.

In fact, according to the invention, said plate of fixing 3 is defined by a metal sheet 8, in particular of hard metal, such as steel, extending from this sheet 8, substantially perpendicularly, at least one leg 9, 9A, so  a fork 4, 4A is defined.

After all, from this sheet 8 you preferably extend a number of legs 9, 9A equal to that of the forks 4, 4A of which the fixed part 2 is provided.

In the embodiment corresponding to the figures of the attached drawing, sheet 8 is folded in its ends, so that you define these legs 9, 9A corresponding to said forks 4, 4A.

Advantageously, in the inner corner 10, enter the sheet 8 and a leg 9, 9A, a rib of reinforcement (not shown in the drawings), for example obtained by an elbow of material.

In order to reinforce the mechanical resistance of the articulation hardware 1, the sheet 8 adopts a section in U-shaped part that extends 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 inserted in wall light Against the frame, it is fenced with flanges 15, 16.

Preferably and as already indicated above, these flanges 15, 16 extend substantially over the entire length of the sheet 8, so that its ends 17, 18 substantially coincide with legs 9, 9A and that can be locked in a molding we are going to refer to now.

For this purpose, at least one of the legs 9, 9A, corresponding to the forks 4, 4A, receives, by molding, maintenance and / or safety means 19, 24 for the joint shaft immobilization 5.

Thus, through this, they can be associated axial translation immobilization means 19 of the shaft articulation 5. In particular, at the level of the ends 20, 21 of this articulation axis 5 can be made a groove in the form of a peripheral throat 22, of chamfered edges, and in which it is able to insert, elastically, a locking clip 23, in shape of an elastic metallic thread, anchored at the level of said molding performed on legs 9, 9A constituting said forks 4, 4A, even in each of them.

For this purpose, it will be noted that the present invention is in no way limited to such design of these immobilization means in axial translation of the axis of articulation 5. In particular, they are already described, in the document FR-A-2,773,377, such means of immobilization, carried out according to another embodiment, which could perfectly be seen in combination with a hardware of articulation of features according to the present invention.

Also, a leg 9, 9A may be provided by molding of additional locking means 24, control manual, whose function is also to prevent any axial displacement of the articulation axis 5, once definitely mounted the leaf of the door or window in its frame and, therefore, having led in cooperation with the fixed part 2 the movable part of the articulation hardware 1.

After all, such blocking means 24 they are intended, on the one hand, to prevent the articulation axis 5 can be unintentionally released from joint hardware 1 and, on the other hand, allow an operator to be safe, during assembly, that this axis of articulation has been effectively inserted, in its entirety, at the level of the mobile part and the fixed part.

Indeed, during this assembly and under the effect of a resistance eventually conferred by the means of immobilization 19, the operator could be led to think that this articulation axis 5 is in total insertion position, when It really isn't.

According to the embodiment visible in particular in figures 4 and 5, said locking means 24, associated by molding at least with the lower fork 4, are defined by an intended locking tab 25 capable of being pushed manually and / or elastically on the axis path of joint 5, below the lower end 20 of the latter.

As it is specified, this tab of lock 25 may be elastic in nature, so that it is pushed below this end 20 of the articulation axis 5. In this case, said blocking means 24 also contain retention means 26, under elastic tension, of said locking tab 25 in unlocked position, visible in figure 4. In particular, such retaining means 26 may be presented in the form of a hook planned capable of cooperating with a hooked flange 27 that It has, at its end, the locking tab 25.

However and according to another embodiment, said locking tab 25 may have a certain flexibility that allows you to push it, using such a tool as a screwdriver, depending on the case in the unlocked position, such and as visible in figure 4, or in locked position represented in figure 5, the retention means 26 being in Such a case, useless.

Preferably, such blocking means 24 are associated with each of the legs that define the forks of end 4, 4A. In fact, it is advantageously conferred on the fixed part. 2 of the articulation fitting 1 a symmetrical shape with respect to a transverse median plane P that authorizes this part fixed 2 and, therefore, its reversibility.

Finally, it will be observed that, due to the greater resistance that confers on the fixed part 2 of a fitting of joint 1 a fixing plate 3 made exclusively by a sheet of hard metal, in particular of steel, the means of maintenance and / or safety 19, 24 for shaft immobilization of articulation 5 can be made by molding on the legs 9, 9A of a material not necessarily metallic, but also synthetic. In fact, almost all the efforts applied by the articulation shaft 5 on the forks 4, 4A comes directly impacted by said legs 9, 9A on this sheet 8 corresponding to the fixing plate 3 which is larger rigidity.

Obviously, at the level of this sheet 8 they can be made a certain number of holes 28 for the passage of fixing organs, such as screws. You can also receive, if necessary, indexing holes 29 for good  positioning in the injection mold for the realization by molding said maintenance means and / or security 19, 24. However, this indexing can, in that case, intervene anyway. By way of example, sheet 8 can be caught from its longitudinal sides 11, 12, for its positioning during molding.
