Description

The invention relates to hinge fittings for a door, window or similar tilt-and-turn and the opening frame of which is partially overlapping the frame, composed of an angle support and a stop compass fixed in rebates and comprising, both, an auxiliary compass arm connected, on the one hand, to the lower cross member, respectively, upper of the frame and, on the other hand, to the lower cross member of the chassis opening, respectively, to an arm of main compass cooperating with the upper cross member of the latter.

Known fittings are already known for a tilt-and-turn door or window housed in rebates of the opening frame and of the fixed frame and corresponding to the description above.

Thus, these fittings consist of an articulation element, called stop compass, intervening in the upper part of the door or window and whose function consists, on the one hand, in ensuring a rotation of the opening leaf around a vertical axis, during the French opening and, on the other hand, to limit the tilting of this opening in the flap position.

They also include another articulation element, called a corner support, placed in the lower part of the door or window and allowing, alternatively, a tilting of the leaf around a horizontal axis and its pivoting according to a vertical axis of rotation.

Due to aesthetic criteria, but also of improvement in terms of safety, it is a current trend to insert these articulation elements in rebates of the opening and the frame of the door or window.

Thus, there is already known a stop compass formed by a main compass arm, the ends of which are slidably mounted, respectively, on the upper cross member of the leaf and the upper cross member of the frame. In addition, a first link is arranged between the compass arm and the opening frame and a second link connects this same compass arm to the frame.

Furthermore, a corner support is also known, composed, on the one hand, of a vertical axis attached to the end of the lower cross member of the opening, hinge side, and comprising a roller, mounted to slide in a slide. fixed on the lower cross member of the frame. On the other hand, a link connects the latter to the opening.

This arrangement has the effect of causing the offset, in a direction parallel to the plane of the door or window, of the axis of rotation of the opening frame, during the French opening, and thus release the rear upright of this opening relative to the sleeping frame.

In the event of opening by folding down, only the existing play of the axis, fitted with its roller, in the slide located on the frame, authorizes the pivoting of the opening around a horizontal axis.

In fact, the solution of this angle support and this known stop compass only corresponds to doors or windows whose opening is flush with the sleeping frame. In case of partial overlap and due to the rebate position of the fictitious axis of rotation of the opening, it is necessary, when opening the French way, to offset this fictitious axis of rotation outside the vertical plane from the door or window.

For this purpose, stop compasses and angle supports of design which are substantially identical to those described above have been designed and which furthermore comprise an auxiliary compass arm, connected, by means of articulations, according to the case, at the upper or lower cross member of the frame and at the rear end of the main compass arm or at the lower cross member of the opening. This arrangement has, however, required the sliding mounting of the various links, to which reference is made above, on said lower cross member of the opening or on the main compass arm.

It follows that, at the time of the French opening, the rotation of the auxiliary compass arm causes the offset, relative to the sleeping frame, of the rear upright of the sash and, simultaneously, the offset of the axis of fictitious rotation of the latter outside the plane of the door or window, more precisely, towards the interior of the dwelling.

Although providing a solution to the problem of openings with partial recovery of the frame, referred to above, these articulation fittings have, however, a drawback, namely their limited application to openings of reduced size and weight.

Indeed, it should be noted that due to the offset of the opening outside the sleeping frame, during the French opening, the auxiliary compass arm and the link of the angle support are required to support the full weight of the sash. These constraints tend to increase in proportion to the opening angle of the door or window. In addition, the proximity of the articulations, connecting the link and the auxiliary compass arm to the sleeping frame, poses a problem in terms of safety when their attachment is torn off on their respective support, in particular in the fully open position. French-style.

Solutions have been proposed to compensate for the load constituted by the opening provided with such built-in locking fittings. In particular, an additional compass arm was added to the angle support, an arm attempting to create a point of connection to the sleeping frame distant from the axis fictitious rotation of the opening and, in particular, of the articulation of the auxiliary compass arm connecting the latter to the lower crossmember of said sleeping frame. This additional compass arm is, moreover, attached to one of its ends, in a sliding manner, on the lower cross member of the opening.

Thus, document DE-A-3,601,278 discloses a corner support capable of taking up a position in the rebate of a door or window, the opening of which is partially overlapping the frame. In fact, this angle support is composed, according to a first embodiment of an auxiliary compass arm connected, at its ends, on the one hand, to the lower cross member of the frame and, on the other hand , at the lower cross member and near the rear upright of the opening. This angle support further comprises a link also made integral by means of articulations, on the one hand, of the lower cross member of the frame and, on the other hand, of the lower cross member of the opening .

It will be noted that the articulations connecting the auxiliary compass arm and the link to the opening are, necessarily, close to each other, an arrangement which is hardly adapted to heavy opening.

According to another embodiment described in this prior document, the auxiliary compass arm is pivotally mounted, at one of its ends, on a slide capable of moving in a slide arranged on the lower cross member of the frame. While a connecting rod, in this case of greater length is pivotally attached, at its ends, on the one hand, on the lower cross member of the opening and, on the other hand, on the lower cross member of the frame. In addition, a secondary lever arm ensures a better distribution of the forces of the connecting rod on the opening. To this end, it is mounted articulated, at one of its ends, on said connecting rod while its opposite end is pivotally mounted on the aforementioned slide. In fact, in the context of this second embodiment, the offset of the opening, in a direction parallel to the plane of the frame, is greater compared to the initial solution.

In all cases, the angle support proposed in this prior document, whatever its embodiment, does not allow the sash to be printed with a rotation greater than 90 °, the peripheral rim of the latter, coming to abut , each time, against the auxiliary compass arm.

Furthermore, document EP-A-O.112.681 discloses hinge fittings having a structure strictly identical to the angle support corresponding to the second embodiment described in the document cited above. Therefore, they take up the disadvantages.

In fact, the present invention aims to remedy all of the aforementioned drawbacks and proposes to design articulation fittings and, in particular, a corner support and a stop compass with identical technical characteristics and capable of take a position, with a smaller footprint, in the rebates of a door, window or the like, the opening of which is partially overlapping the frame.

More specifically, the reduction in the size of this corner support and of this rebate stop compass must be obtained by avoiding the multiple compass arms connecting, usually opening it to the frame without it being necessary to limit the application of these hinge fittings to openings of reduced size and weight. Also, it is advisable to ensure a better distribution of the forces on the constituent elements of these articulation fittings.

Furthermore, these hinge fittings must be able to allow an opening angle of the opening greater than 90 °.

There is a last objective which it is advisable to achieve thanks to the present invention and which consists in a minimum reduction in the amplitude of the displacement of the rear upright of the sash relative to that of the frame in a direction parallel to the plane of the door or window, so as to provide the largest possible opening.

The invention, as characterized in the claims, solves the problem of creating hinge fittings for a tilt-and-turn door or window and the opening frame of which is partially overlapping the sleeping frame, composed of a compass '' stop and a corner support fixed in rebates and both comprising an auxiliary compass arm connected, on the one hand, to the upper crossbar, respectively lower of the frame, and, on the other hand, to the main compass arm cooperating with the upper cross member of the chassis opening respectively, at the lower cross member thereof, the stop compass and the angle support comprising, in addition:
- A second compass arm mounted to slide at one of its ends, on the upper, respectively, lower cross member of the frame, and the other end of which is connected by means of articulation, to said main compass arm , respectively, to the lower cross member of the opening frame
- And a connecting rod, one end of which is articulated on this second compass arm, the other end being pivotally attached to the upper, respectively lower cross member of the frame.

The advantages obtained thanks to this invention consist, essentially, in that the sliding connection of the second compass arm to the upper or lower cross member of the sleeping frame makes it possible to move, as far as possible, the point of attachment which it constitutes to the frame dormant relative to the point of articulation of the auxiliary compass arm on these same upper and lower crosspieces. There is thus obtained a better distribution of the load that the opening constitutes on these articulation fittings and, more particularly, on the angle support.

However, it will be noted that this advantage is not at the expense of the angle of rotation of the opening element in the case of French opening, this angle possibly reaching values much greater than ninety degrees.

In addition, the advantage of hinge fittings of identical design to achieve both the high and low connection of a tilt and turn leaf to the frame of the door or window, allows to obtain a standardization of certain of their constituent elements and lead to simplified manufacturing and storage management.

The hinge fittings, according to the invention and shown in Figures 1 to 4, apply to doors or windows whose opening 1 is of the tilt-and-turn type. Thus, this opening 1 is able to pivot about a vertical axis, passing through the rear upright 2 and corresponding to a so-called French opening position. Furthermore, this opening 1 can tilt around a horizontal axis, frequently materialized, by its lower cross-member 3, such an opening corresponding to the position when folding down.

Among the various tilt-and-turn opening elements, there are those with partial overlap of the sleeping frame 4. Such opening elements 1 have, on their periphery, a flange 5 which is applied, in the closed position, on the internal face 6 of said frame. dormant 4 and thus contributing to better sealing of the door or window.

The present invention applies, more precisely, to such opening and relates to articulation fittings taking place in rebates 7, 8 of the frame 4 and of the opening frame 9.

These articulation fittings consist of a corner support ensuring the low connection of the opening 1 to the frame 4 and a stop compass 11 constituting the high connection of the latter. Thus, the angle support 10 allows, at the same time, to give the opening 1 a rotation about a vertical axis and a rotation about a horizontal axis, while the stop compass 11 ensures the pivoting around a vertical axis of the main compass 12 which, because of its connection to the opening 1, reflects this rotation on the latter. This stop compass 11 also makes it possible to limit the tilting angle of the opening 1 during its rotation about the horizontal axis.

More precisely, the angle support 10, as shown in FIGS. 1 and 2 comprises, on the one hand, an auxiliary compass arm 13 connected, at one of its ends 14, and using means of articulation 15, to the lower cross member 3 of the opening frame 9. Preferably, this connection of the auxiliary compass arm to the opening 1 is located as close as possible to the lower angle 16 of the latter. A hinge 17 connects the auxiliary compass arm 13 to the sleeping frame 4 and, in particular, to a support 18 formed by an elongated plate 19 attached by means of fastening elements in rebates 7, on the lower cross member 21 of said sleeping frame 4.

The main interest of this auxiliary compass arm 13 consists, during the French opening, in clearing the rear upright 2 of the opening 1 relative to the rear upright 22 of the sleeping frame 4 and, simultaneously, deporting said opening 1 in a direction perpendicular to the vertical plane 23 of the door or window. This offset is preferably carried out towards the interior of the dwelling.

It should, in fact, be noted that due to the arrangement of rebates of the articulation fittings, it is essential to confer on a sash partially overlapping the sleeping frame 4, such kinematics without which its peripheral edge 5, cooperates with the internal face 6 of said frame 4 and prevents its rotation about a vertical axis and, therefore, the French opening.

The angle support 10 comprises, on the other hand, and according to a characteristic of the invention, a second compass arm 24 connecting the opening frame 9 to the sleeping frame 4. More specifically, this compass arm 24 is slidably mounted , at one of its ends 25, on the lower cross member 21 of the fixed frame 4, while the other end 26 is fixed, by a hinge 26A, in rebate 8 and on the lower cross member 3 of the opening frame 9.

According to a preferred embodiment, the sliding mounting of this second compass arm 24 on the sleeping frame 4 is obtained by means of a slide 27 arranged in the support 18 applied to the lower cross member 21 of said sleeping frame 4. This slide 27 consists, in fact, of an oblong opening 28, arranged in the plate 19 and, in particular, in its front part 29 oriented towards the front upright of the sleeping frame 4. In the opening 28 is engaged a pin 30 fixed to the end 25 of the second compass arm 24 and projecting from the underside 31 of the latter. This pin 30 is moreover provided, at its free end 32, with a flange 33 cooperating with the lower side 34 of the plate 19. It thus avoids the unexpected release of the second compass arm 24 from the slide 27 during handling the sash 1.

Preferably, flanges 35, 36 are arranged on the lower side 34 of the plate 19, at the longitudinal edges 37, 38 of the opening 28. This characteristic makes it possible to improve, appreciably, the quality of the guide of the pin 30 and thereby contribute to a reduction in clearances existing between the various constituent parts of the angle support 10. It will be noted, however, that such an improvement does not, in any case, result in an increase in the thickness of the plate 19. In fact, these flanges 35 , 36 can be obtained by a simple inexpensive stamping operation.

Advantageously, the angle support 10 is also provided with a link 39 mounted articulated, at one of its ends 40, on the second compass arm 24 and cooperating, by means of a joint 41, and at its end. opposite 42, with the support 18 or plate 19. This rod 39 has the main function of distributing the action of the compass arms 13 and 24 over the opening 1. For this purpose, it will be noted that the articulation 41, connecting this rod 39 to the support 18, is preferably located between the opening 28 and the articulation means 15 of the auxiliary compass arm 13. In fact, the articulation 41 of the rod 39 is disposed as close as possible to these means hinge 15 to allow the opening angle of the opening 1 as large as possible. Due to the characteristics of the present invention, this opening angle of the opening 1 can reach values much greater than ninety degrees.

Note, moreover, that in position perpendicular to the vertical plane 23 of the door or window, the opening 1 has points of attachment to the sleeping frame 4 relatively distant from each other. It therefore retains impeccable stability regardless of its weight and size.

According to a preferred embodiment of the invention, the second compass arm 24 is arched in the middle 43 allowing the insertion of the link 39 between said second compass arm 24 and the plate 19, in the closed position of the opening 1. However, care is taken that the overall thickness 44 of the angle support 10 is kept less than the clearance existing between the rebates 7, 8 of the frame 4 and of the opening frame 9 so as to avoid any nicking of one of the latter.

As for the auxiliary compass arm 13, located in the closed position of the opening 1, in the extension of the second compass arm 24 and the link 39, it is chosen to have a thickness 45 equivalent to the sum of the latter. Thus, reinforced, this auxiliary compass arm 13 is able to support the weight that constitutes the opening 1 when the latter is offset outside the vertical plane 23 of the door or window.

For the same purpose of mechanical strength of the angle support 10, in the case of application to large and large openings, the articulation 17 connecting the auxiliary compass arm 13 to the sleeping frame 4 is formed by a vertical axis 46 widely introduced into the lower cross member 21 of the latter. Furthermore, the end 47 of this vertical axis 46, projecting from the support 18, is engaged in a bore 48 arranged at the end 17A of said auxiliary compass arm 13.

Regarding the stop compass 11, apart from the main compass arm 12, it has a structure substantially identical to the angle support 10. Thus, as shown in Figures 3 and 4, it has a compass arm auxiliary 113, connected, at one of its ends 114 and by means of a joint 115, to the rear end 116 of said main compass arm 12. Furthermore, a joint 117 ensures the connection of this auxiliary compass arm 113 at its opposite end, with a support 118 formed by an elongated plate 119 made integral, by means of fastening elements 120 in rebate 7, on the upper cross member 121 of the frame 4.

This stop compass 11 is also provided with a second compass arm 124, one end 125 of which is slidably mounted in a slide 127 arranged in the support 118. The other end 126 of this second compass arm 124 is made secured to the main compass arm 12 using a joint 126A.

The structure of the slide 127 is identical to that described in the context of the angle support 10. Thus, it is formed by an oblong opening 128 arranged in the plate 119. This comprises, on its face 134, oriented in the direction of the upper cross member 121 of the fixed frame 4, the flanges 135, 136, located on the longitudinal edges 137, 138 of the opening 128. In this slide 127 is engaged a pin 130 secured to the end 125 of the second arm of compass 124, journal 130, comprising at its free end 132, a flange 133 cooperating with the flanges 135, 136 and preventing its release from the opening 128.

A link 139, mounted articulated at one of its ends 140 on the second compass arm 124, also connects the latter to the upper cross member 121 of the frame 4. For this purpose, this link 139 cooperates, at its end 142, with the support 118 by means of a joint 141 disposed in the immediate vicinity of the joint 117 connecting, to this same support 118, the auxiliary compass arm 113.

Again, the second compass arm 124 has, in its middle 143, a camber allowing, in the closed position, the engagement of the link 139 between said second compass arm 124 and the plate 119. However, it will be noted that the auxiliary compass arm 113 is not necessarily reinforced since it contributes only a small part to the support of the weight of the door. Under these conditions, the difference 144 existing between said auxiliary compass arm 113 and the plate 119 is compensated by a boss 145 on the lower face 146 of the latter and on which the articulation 117 is mounted.

It should be noted that, within the framework of the angle support 10 as well as of this stop compass 11, the joints 17, 117 and 41, 141, connecting the auxiliary compass arm 13; 113 and the link 39, 139 to the support 18, 118 are brought together as close as possible to one another and arranged as close as possible to the rear upright 22 of the frame 4.

As for the main compass arm 12, this is connected to the opening 1 according to techniques known to those skilled in the art. Thus, the front end 147 is provided with a pin (not shown) slidingly mounted in an oblong slot 148 arranged in a headrest 149 arranged in rabbet 8 on the upper cross member 150 of the opening frame 9. More precisely, this headrest 149 covers a groove 151 produced at the periphery of the opening 1, and in which maneuvering rods actuated by a locking mechanism slide, such as a cremone bolt or cremone bolt. In addition, a link 152 connects the main compass arm 12 to the opening frame 9, preventing the latter from shifting relative to the sleeping frame 4 in the event of opening by folding down.

Maintaining the main compass arm 12 on the headrest 149 in the French open position can be ensured by any known means such as strikes integral with said main compass arm 12. These strikes are thus able to cooperate with members locking fixed on an operating rod and emerging from the headrest 149 through openings made for this purpose. However, due to the size of the stop compass 11 in rebates 7, 8 of the sleeping frame 4 and the opening frame 9, it would be necessary to strongly offset the above strikes relative to the vertical axis of rotation of the opening 1. However, under such conditions, the slightest play existing between the keeper and the locking member disposed on the operating rod results, for opening large width, by a play of several millimeters at their amount back.

To remedy such a drawback, the rear end 116 of the main compass arm 12 is extended, as shown in FIG. 10, by a section folded in the form of a square 155 coming in the French open position, cover the upper corner 153 of the opening frame 9 and, in particular, of the headrest 149. In the vertical wing 156 of this section folded in the shape of a square 155 is made a hole 157 in which the end 158 d engages 'an operating rod 159 emerging from the rear vertical edge 154 of said opening frame 9. In contrast, the control of the bolt or lever-lock, when opening by folding, causes the withdrawal of this projecting end 158 of the operating rod 159 thus releasing the main compass arm 12.

As regards the pivoting of the opening frame 9 with respect to the sleeping frame 4, along a horizontal axis of rotation, it can be made possible, by virtue of a sufficient clearance at the articulation 17 connecting the auxiliary compass arm 13 to the support 18.

More specifically, the projecting end 47 of the axis 46, to which reference was made above in the description, is conical in shape and introduced into the bore 48 arranged in the end 17A of the auxiliary compass arm 13. Such a configuration allows the latter to pivot, at a limited angle, around a horizontal axis.

Under these conditions, the articulation means 15 connecting this same auxiliary compass arm 13 to the leaf 1, consist of a vertical axis 49 made integral, at its lower end 50, with the free end 14 of said arm auxiliary compass 13. In addition, a bracket 52 covers the lower corner 16 of the opening 1 and fits into notches 53, 54 arranged in the rear upright 2 and the lower cross member 3 of the opening 1 and serving, usually, housing the operating rods and the headrest. This bracket 52 is made integral with the opening 1 by means of fastening elements such as screws or the like and comprises, in its lower edge 55 and in the angle 56, a cylindrical recess 57 with dimensions adjusted to those of the axis 49 to allow passage and the rotation of the latter.

In certain cases, in particular for ranges of more or less significant opening, such a clearance at the level of the connection of the auxiliary compass arm 13 on the support 18 can represent a disadvantage being at the origin of a faster fatigue of the component parts of the hinge fittings.

Under these conditions, and according to another embodiment, in accordance with the invention, and represented in FIGS. 5 to 9, the projecting end 47 of the axis 46 is adjusted to the diameter of the bore 48 present in the auxiliary compass arm 13 so that only rotation about a horizontal axis thereof is allowed.

In addition, the vertical axis 49 constituting, in part, the articulation means 15 of said auxiliary compass arm 13 to the opening frame 9, is introduced into an oblong opening 57A machined in the lower edge 55 and in the angle 56 of the bracket 52. This oblong opening 57A communicates with a recess 58, preferably of cylindrical shape, with a vertical axis and produced in the vertical wing 59 of said bracket 52. A socket 60, integral with a transmission rod 61 , slides in this recess 58 and cooperates with the vertical axis 49.

More specifically, the sleeve 60 has on its underside 62 a blind hole 63 adjusted to the diameter of the vertical axis 49 to allow the introduction.

As for the transmission rod 61, connected to the sleeve 60, it emerges from the recess 58, at the level of the upper edge 64 of the vertical wing 59 corresponding to the bracket 52. This transmission rod 61 is thus able to cooperate, at its upper end 65 and using connection means 66, with an operating rod (not shown). This is housed in the notch 53 present in the rear upright 2 of the opening 1 and cooperates with the locking mechanism, such as a cremone bolt or a cremone bolt.

Therefore, under the action of this operating rod, controlled by said locking mechanism, the sleeve 60 is caused to slide in the recess 58 of the bracket 52 cooperating or not cooperating with the axis, as the case may be. vertical 49. More precisely, in the closed position of the opening 1, corresponding to FIG. 7, the sleeve 60 is fully engaged on the vertical axis 49. By actuating the locking mechanism, to control the French opening of the door or window, the play of the operating rods causes the socket 60 to rise, the latter being held in the partially engaged position on the vertical axis 49, as visible in FIG. 8. This vertical axis 49 is, in this case, able to rotate around a vertical axis.

Finally, in the open position by opening the opening 1, corresponding to the configuration of the articulation means as shown in Figure 9, the sleeve 60 is fully raised in the recess 58, freeing the vertical axis 49 .

Therefore, and due to the oblong opening 57A arranged in the bracket 52, the latter is able to pivot about a horizontal axis. However, to avoid limiting the angular displacement of the vertical axis 49 inside the recess 58, the bracket 52 and, in particular, the vertical wing 59 has, near the angle 56 and on its face 67 facing outwards from the door or window, an opening 68. The latter, thus arranged in line with the vertical axis 49, allows the free end 69 thereof to emerge from the bracket 52 in the maximum tilting position of the sash 1.

It is undeniable that such a configuration improves the holding of the opening frame 9 relative to the sleeping frame 4, in the event of the French opening of the door or window.

Consequently, the angle support 10 and the stop compass 11, objects of the present invention, provide indisputable advantages in the field of recessed hinge fittings for tilt-and-turn door or window. Indeed, their particular design allows their application to large size and weight openings with impeccable reliability and while ensuring a French opening angle greater than ninety degrees. These articulation fittings, in accordance with the invention, thus combine efficiency and aesthetics.
