Abstract

An articulated fitting for a door, window or the like, of which the wing (2) pivots outwards about a vertical axis in relation to a fixed frame (3), comprises a main swivel arm (6) and a secondary swivel arm (7), both connecting the support plates (10, 14) fastened to the lower transoms of the fixed frame (3) and of the wing (2). So as to guarantee excellent sealing and a perfect retention of the wing against the fixed frame level with their rear mullion (16, 17), this articulated fitting also comprises means (18) for locking said wing (2) and laying it against the fixed frame (3) exactly level with their mullions (16, 17), and adjustment means (34) for modulating the intensity of the force with which the wing (2) is laid against the fixed frame (3) by these means (18). <IMAGE>

Description

The invention relates to a hinge fitting for a door, window or the like, the opening of which pivots outwards relative to a fixed frame, this around a vertical hinge axis, in accordance with the preamble of claim 1. The preamble of the claim is known from document EP-A-0 364 698.

Already known from the same document, a hinge fitting for door, window or the like which has the distinction of having its elements arranged in rebate. In fact, according to an embodiment described in this document EP-A-0.364.698, the articulation fitting is provided with a main compass arm and a secondary compass arm, having one of their ends hinged mounted on a support plate fixed on the lower cross member of the frame. The other end of this main compass arm and of the secondary compass arm is, moreover, hinged mounted on a support plate attached to the lower cross member of the leaf.

It is further observed that the articulation connecting the secondary compass arm to the opening is located as close as possible to the rear upright of the latter.

Thus, starting from the closed position of the door, window or the like, the command to open the latter leads to a combined movement of the opening, namely a rotation of the latter around a vertical axis lying up to its rear upright and a projection of the latter outside the sleeping frame resulting from the rotation of the secondary compass arm around the articulation connecting it to the support plate fixed to said sleeping frame.

This projection of the opening outside the sleeping frame is of interest, more particularly, in the case where the rebate of said opening is partially overlapping the sleeping frame, that is to say that this opening has a peripheral rim coming in applies, in the closed position of the window, door or the like, on the internal or external face of the frame.

Because of their technical characteristics, and more particularly of the fact that they have the obligation to project, outside, the rear upright of the opening outside the frame, these articulation fittings pose the problem of maintaining applies, with a certain seal, the opening against said frame, precisely, up to their rear upright.

To remedy this problem, there are provided, according to this document EP-A-0.364.698, means intended to apply said opening against the sleeping frame, precisely, at the height of their rear upright, when closing the door, window or the like. These means are in the form of a slide which can be mounted either on the support plate of the sleeping frame, or on that of the opening. The movement of this slide is controlled under the combined action of a control finger and a cam, one of which is fitted to the main compass arm and the other of which is located at the front end of the slide.

More precisely, when closing the opening, this combined action of the control finger and the cam results in moving said slide in the direction of the rear upright of the opening and of the sleeping frame. Thus, in the case of the mounting of this slide on the support plate of the opening, its end, oriented in the direction of the rear upright, is bevelled so as to engage at the rear of a support ramp. Finally, this cooperation of the support ramp and the beveled end of the slide leads to compression of the opening against the fixed frame.

Furthermore, in the case of an arrangement on the support plate of the sleeping frame, the slide comes to move towards the rear upright of said sleeping frame under the combined action of the control finger and the cam when closing the 'opening. Thus, this slide, the end of which is oriented in the direction of said rear upright of this sleeping frame is bevelled, comes to be positioned at the front of a locking stud extending the axis of articulation of the compass arm secondary to the opening. The progression of this stud on the beveled face of the end of the slide produces the compression of said opening against the fixed frame, precisely, at the level of their rear upright.

The major drawback of this type of hinge fitting consists in that their means intended to apply the opening against the sleeping frame, at the level of their rear upright, are limited, precisely, to this compression function. However, it is observed that a lesser clearance at the rear upright of the opening, resulting, for example, from a reduced stiffness coefficient of the seal makes it possible, under the effect of repeated pulses, to gradually take off, said rear upright of the opening relative to the sleeping frame and push the slide that it is located on the opening or on the sleeping frame. It is noted, in fact, that when closing the door, window or the like, the movement control of the slide is ensured through the combination of a control finger and a cam. However, it is substantially the same type of cooperation of a control finger and of cam which leads to the compression of the opening against the fixed frame. Thus, there is every reason to consider that by exerting on the opening an action contrary to that which led to its compression against the sleeping frame, one is able, effectively, to also ensure the release of the slide.

In fact, if it is true that this leads to a lesser tightness of the door, window or the like, it is no less true that security is also at issue. Indeed, once the rear upright of the opening offset relative to the sleeping frame, it is easy, at a sharp end to introduce, at the level of the gap, thus created, a tool for fracturing said door, window or the like.

Such a hinge fitting is also known from document GB-A-2,216,594. In fact, the embodiment described in this prior document corresponds to the case where the slide is mounted on the support plate attached to the sleeping frame. The displacement control of this slide is effected under the combined action, on the one hand, of a control finger equipping an auxiliary compass arm connected to the main compass arm and, on the other hand, of a cam located at the height of the front end of the slide. It also includes, at its rear end, a ramp which, when the opening is closed and, therefore, when this slide is moved, acts on a lug associated with a second auxiliary compass arm connecting the main compass in the frame. This action of the ramp on the lug actually makes it possible to compress the sash against the frame.

Thus, the object of the invention is not only to guarantee a good seal of the opening at the level of its rear upright, this with respect to the sleeping frame by means of suitable compression means, but also to produce a locking of this opening against said sleeping frame precisely at the height of the rear uprights, so that an action attempting to move this opening from the sleeping frame, once the locking has been carried out, does not make it possible to modify the position of the slider and therefore , the intensity of the compression of said opening against the sleeping frame.

Note, in this regard, that the pressure with which the opening is applied against the sleeping frame must not decrease, even in the event of progressive deterioration of the seal, precisely, to obtain a constant and quality seal. The invention also proposes to provide a solution to this problem.

• a) lesdits moyens pour appliquer l'ouvrant contre le cadre dormant à hauteur de leur montant arrière, constituent, en outre, des moyens de verrouillage aptes à verrouiller l'ouvrant contre le cadre dormant à hauteur de leur montant arrière, ledit premier élément de verrouillage étant constitué par un galet venant à coopérer avec ledit deuxième élément de verrouillage sous forme d'une gâche à rampe, faisant partie desdits moyens de verrouillage et comportant un prolongement prévu pour se situer dans une direction parallèle au plan de l'ouvrant, dans le sens du montant avant opposé au montant arrière de l'ouvrant et dans lequel s'engage ledit galet en fin de verrouillage ;

Finally, the invention proposes to remedy all of the aforementioned drawbacks. The invention, as characterized in the characterizing part of claim 1, solves this problem and consists of a hinge fitting for a door, window or the like, the opening of which pivots outwards relative to a frame frame, this around a vertical articulation axis located at the height of the rear uprights, respectively, of the sash and of the frame, comprising, on the one hand, a main compass arm and a secondary compass arm, both being mounted articulated at one of their ends on a frame support plate capable of being fixed on the lower cross member of the frame and, at the height of the other of their opposite ends on a sash support plate , intended to be attached to the lower cross member of the opening and, on the other hand, means provided for applying the opening against the sleeping frame at the height of their rear upright, these means being formed by a slide water mounted on the frame support plate and comprising a first locking element which cooperates with a second locking element equipping the rear end of the opening support plate, intended to be located near said vertical articulation axis, this when controlling the movement of this slide under the combined action of a control finger and a cam, one of which equips the opening support plate, the other being integral with said slide, characterized by the fact than :

• a) said means for applying the opening against the sleeping frame at the height of their rear upright, constitute, in addition, locking means capable of locking the opening against the sleeping frame at the height of their rear upright, said first element locking being constituted by a roller coming to cooperate with said second locking element in the form of a ramp strike, forming part of said locking means and comprising an extension provided to be located in a direction parallel to the plane of the opening, in the direction of the front upright opposite the rear upright of the opening and in which engages said roller at the end of locking;
• b) and that the articulation fitting comprises, in combination, adjustment means making it possible to modulate the intensity of the force according to which the opening element is applied against the sleeping frame, these adjustment means being constituted by said roller which is associated with the slide and is in the form of an eccentric making it possible to modify, transversely, its position on said slide and, therefore, the return force imparted to the opening during the cooperation of this roller with the ramp strike .

The advantages obtained thanks to this invention consist, essentially, in that one obtains, not only, a perfect tightness of the opening relative to the sleeping frame, once the door or window is closed, but, moreover, a guarantee increased security in the context of this type of door or window fitted with hinge fittings arranged in the rebate of the leaf and the frame.

Other objects and advantages of the present invention will become apparent during the description which follows and whose understanding will be facilitated by referring to the attached drawings:

• Figure 1 is an elevational view of the hinge fitting according to the invention;
• Figure 2 is a plan view of this hinge fitting and corresponding to an open position of the opening relative to the frame;
• Figure 3 is a representation of this hinge fitting in a position being closed the opening;

As shown in the various figures, the present invention relates to a hinge fitting 1 for door, window or the like, the opening 2 of which pivots outwards and around a vertical axis relative to a frame. dormant 3. This type of opening is generally said to be English.

More specifically, this opening 2 of these doors, windows or the like opening in the English fashion is usually partially overlapping the sleeping frame 3, that is to say that it has a rim 4 coming from the periphery. applied, in the closed position, on the external face 5 of said frame 3.

Furthermore and precisely because of this outward rotation of the opening 2, this hinge fitting is arranged in the rebate of the door, window or the like and, more particularly, between the lower and upper crosspieces of said opening 2 and the sleeping frame 3. In reality the low hinge fitting is substantially identical to that used at the top of the door or window. There can, however, be a distinction in terms of the resistance of the parts that compose them, knowing that the low hinge fitting is generally required to support the weight of the opening leaf 2.

Thus, such a hinge fitting 1 comprises a main compass arm 6 and a secondary compass arm 7 having one of their ends 8, 9 hinged mounted on a frame support plate 10 coming to be fixed on the lower cross member or upper 11 of the sleeping frame 3. As for the level of their opposite end 12, 13, this main compass arm 6 and the secondary compass arm 7 are pivotally mounted on a leaf support plate 14 attached to the lower or upper cross member 15 of the opening 2.

The main and secondary compass arms 6 have the function, essentially, on the one hand, of ensuring the pivoting around a vertical axis of the leaf 2 relative to the frame 3 and, on the other hand, of 'generate, during this rotation, a slight projection of the opening 2 outside of this frame 3 so that the peripheral rim 4 does not interfere with this rotation by coming to bear on the outer face 5 of said frame 3 .

Thus, the secondary compass arm 7 comes to be located, relative to the main compass arm 6, as close as possible to the rear uprights 16, 17, respectively of the leaf 2 and of the frame 3.

In fact, the problem posed by these articulation fittings, for a door or window opening in the English style, is linked to the difficulties they have in ensuring, in the closed position of the door or window, the maintenance, in applies and with a certain pressure, the opening 2 against the sleeping frame 3, precisely at the level of their rear upright 16, 17. In addition, there is grafted on this the problem of the constancy of this force of application and compression of the sash on the frame, knowing that due to manufacturing tolerances of both the carpentry and these hinge fittings, there may be variations from one door or window to another.

The present invention proposes, precisely, to provide a solution to these problems and, for this, consists in equipping the hinge fitting 1 with means 18 for locking and applying against the sleeping frame 3, said opening 2 at their height. rear upright 16, 17, these means 18 being formed, more particularly, by a slide 19 coming to be mounted on the frame support plate 10.

In fact, this slide 19 comprises a roller 20 on the side of its end 21 oriented in the direction of these rear uprights 16, 17, this roller 20 being capable of initially cooperating with a ramp arranged, in correspondence, at the rear end 23 of the opening support plate 14. In fact, this ramp is part of a ramp keeper 22 in which the roller 20 engages at the end of locking.

Thus, according to the embodiment illustrated in the drawings, the roller 20 is projecting from the visible face 24 of the slide 19.

This roller 20 comes, at the time of closing of the opening 2, to engage in said striker with ramp 22 in the form of either a cutout 25 arranged in the longitudinal edge 26 of the opening support plate 14 , longitudinal edge 26 oriented in the direction of the sleeping frame 3 and therefore towards the interior of the dwelling, that is to say an attached piece on this opening support plate 14 and the height of which corresponds to a spacing 40 existing between the support plates 10, 14 this in the closed position of the door, window or the like. This ramp keeper 22 has an extension 27 this in a direction parallel to the plane of the opening 2 and in the direction of the front upright opposite to the rear upright 16 of the opening 2, in which, precisely, the roller 20 engages at the end of locking.

In fact, the movement control of this slide 19 during this closing is obtained through a control finger 28 associated with the opening support plate 14, at its end 29, opposite the end 23 provided with the ramp keep 22, this control finger 28 coming to cooperate with a cam 30 secured to the concordant end 31 of the slide 19.

More precisely, when closing the door or window, the control finger 28 engages in a machined cutout 32, at an angle, in the longitudinal edge 33 oriented in the direction of the opening 2, of the slide 19 and forming , therefore, the cam 30. While progressing in this cutout 32, this control finger 28 ensures the axial displacement of the slide 19 on the frame support plate 10, this in the direction of the front upright of the opening 2 and the standing frame 3, so that the roller 20, placed on this slide 19, is inserted into the keeper with ramp 22 located at the end 23 of the leaf support plate 14.

Furthermore, the cutout 32, forming the cam 30 can be fitted in an additional piece 32A attached, as illustrated in FIG. 1, on the visible face 24 and at this end 31 of the slide 19 this in order to guarantee a better mechanical resistance of the latter.

In addition and according to the invention, the articulation fitting 1 also comprises adjustment means 34 making it possible to modulate the intensity of the force according to which the opening 2 comes to bear against the sleeping frame 3.

These adjustment means are constituted, substantially and according to a preferred embodiment of the present invention, by the roller 20 located at the end 21 of the slide 19. In fact, this roller 20 is constituted by an eccentric which, when its position comes to change transversely on said slide 19, causes, due to its cooperation with the strike plate 22 located on the leaf support plate 14, a modification of the restoring force printed on said leaf 2 at the time of closing the door, window or the like.

The slide 19 being affixed to the visible face 35 of a support plate 10 disposed on the lower cross member of the fixed frame 3, therefore on the face on which also comes to be hinged one of the ends 8, 9 respectively, of the main compass arm 6 and of the secondary compass arm 7, this slide 19 necessarily includes, in its longitudinal edge 33 oriented in the direction in which these compass arms 6, 7 extend, cutouts or splayings 36, 37 at right of this articulated mounting of said main compass arm 6 and of the secondary compass arm 7 on this frame support plate 10.

However, these cutouts or splaying 36, 37 obviously have the consequence of weakening this slide 19. According to the invention, the latter is consolidated through a vertical wing 38 lying on its longitudinal edge 39 opposite the longitudinal edge 33 comprising the doorways 36, 37 or the cutout 32 forming the cam 30. The height of this vertical wing 38 is reduced to the distance 40 existing between the support plates 10, 14 this in the closed position of the door, window or the like.

In fact, this vertical wing 38 has another advantage, namely that it constitutes, when this door, window or the like is closed, a protective stop against which the main compass arm 6 and the secondary compass arm 7. Consequently, it preserves the rebate of the sleeping frame 3 from contact with said main 6 and secondary compass arms 7.

Of course, the sliding mounting of this slide 19 on a frame support plate 10 can be obtained by any suitable means. Thus and according to the embodiment illustrated in the accompanying drawings, these connecting means can be in the form of buttonholes consisting of the production, in said slide 19, of oblong slots 41, 42 in which engage pins of guide 43, 44 associated with the frame support plate 10 receiving this slide 19.

Note, moreover, that according to the embodiment presented in the figures of the attached drawings, the support plate 10 has, at its end 45 oriented towards the rear upright 17 of the frame 3, a wing folded vertically 46, coming to act, like a ramp, with the free end 47 of the support plate 14 applied to the opening 2 when the door, window or the like is closed.

In fact and according to the invention, this cooperation of the support plates 10, 14, through their particular ends 45, 47 is not intended to fully ensure the compression function of the opening 2 against the sleeping frame 3 at the time of closing, this function being, more particularly, left to the load of the slide 19. However, it makes it possible to ensure a prepositioning of this opening 2 with respect to the sleeping frame 3 so that, whatever the clearances likely to arise subsequently at the level of the articulated connections of the main 6 and secondary 7 compass arms on the various support plates 10, 14, it is certain, at the time of closing, that the roller 20 fits properly in the ramp keeper 22 in order to ensure, finally, the compression of the opening 2 against the sleeping frame 3 according to a predetermined and invariable force.

Through the foregoing description, it can be seen that the present invention has been able to solve, in an effective and simple manner, a problem which has persisted, until now, in the area of articulation fittings known in the prior state. of the technique for door, window or the like opening in the English style.
