In order to facilitate the reversibility of this folding-arm bearing without disassembling of components, the wing of the blade is provided, on its upper and lower edges, with a pin engaging into an opening made in the connector, and the plate is mounted onto this wing by means of an eccentric having a rotation which generates a vertical movement of the plate causing the disengagement of a pin from the opening present in the connector.

Description

The invention relates to a compass bearing for a tilt-and-turn window opening of doors, windows or the like, comprising a support attached to the internal face of the frame and a blade pivotally mounted on said support and having a square shape so as to define a wing coming to be inserted, in the closed position of the door, window or the like, in the rebate of the latter, on the rear face of this wing being pivotally mounted a plate at the free end of which is fixed a compass arm by through a pivot.

The present invention relates, more particularly, to the industry specializing in building hardware.

A number of compass bearings are already known which are intended to ensure the high connection of an opening leaf to a sleeping frame in particular, of a door, window or the like of the tilt-and-turn type. Very generally, these compass bearings are distinguished from one another according to either their mode of attachment to said sleeping frame, or the nature of the material composing the latter or the size and weight of the door leaf. , window or the like.

Thus, very frequently, these compass bearings comprise a support which decomposes into a fixing plate, intended to be attached to the sleeping frame, and two knuckles arranged on the same vertical alignment on said fixing plate and in which is inserted a brooch. They are further provided with a blade provided with a sleeve pivotally mounted on the aforementioned spindle while being inserted between the two knuckles of the support. The configuration of this blade is generally determined so that it is able to fit into the rebate of the door or window and to cooperate with a compass arm connected to the leaf.

Note that this connection between the blade and said compass arm can be done in different ways.

Thus, in a first case, this blade can be provided with a pivot consisting of a housing comprising a bore with an axis substantially horizontal and lying in the extension of said compass arm. In this bore is inserted the cylindrical rear end of this compass arm to be fixed therein by suitable means. For example, such means may be in the form of a thread arranged on the cylindrical end of the compass arm, thread coming to cooperate with a nut or equivalent located beyond the pivot. Note that such an arrangement makes it possible to adjust the position of the opening relative to its dormant frame in its upper part.

There are also other solutions for ensuring this connection between the blade of the compass bearing and the compass arm. Thus and in accordance with document FR-A-2,614,923, said blade can take an angled shape so as to present a wing which is able to be inserted, in the closed position of the door or window, in the rebate of this last. On this wing is attached, by screwing or the like, the curved end of the compass arm.

The current concern of industrialists specializing in building hardware consists, generally, in standardizing their manufacture so as to reduce the cost price of the various parts while providing a solution to the problem of storage.

In particular, it is necessary to confer on the various constituent parts of a hinge fitting, the characteristics necessary so that they can be reversible, thus allowing their implementation, indifferently, to doors or windows with opening to the right and to left.

In the context of the association of the blade with the compass arm as explained in the document FR-A-2,614,923, this reversibility is linked, on the one hand, to the symmetrical structure of the blade and, d on the other hand, to the possible dissociation of the latter from the compass arm. Thus, it is possible to supply the carpenter ensuring the mounting of these hinge fittings on the doors or windows with a set of spare parts. This carpenter must, later, ensure the assembly and positioning of the different parts together according to the implementation of the hinge fitting on the right or left on a door or window.

Consequently, this solution of supplying the carpenter with spare parts appears to be not advantageous for the latter since this imposes on him an increased time for assembling the hinge fittings and multiplies the nature of the parts stored. Another solution is to deliver this carpenter in pre-assembled hinge fittings for a specific use of the latter, either to the right or to the left of a door or window.

This solution, without degrading the storage conditions at the manufacturer, half solves the problem of the time of assembly and assembly of these hinge fittings by the carpenter. However, it is quite obvious that, to authorize the use, for example, to the left of these articulation fittings intended, initially, for application to the right, this carpenter will have to dismantle them beforehand in order to modify the arrangement of the pieces between them.

In short, this solution does not make it possible to reconcile storage problems at the level of the manufacturer and the imperatives linked to the assembly time for the carpenter.

Furthermore, document FR-A-2.295.207 discloses a compass bearing corresponding to the preamble of claim 1.

The blocking in rotation of the plate relative to the wing arranged in rebate corresponding to the blade is obtained by means of a screw passing through said plate and coming to cooperate with a threaded orifice arranged at the level of said wing. In fact, the latter is provided, on either side of its horizontal median plane, with such a tapped orifice allowing it to accommodate the locking screw corresponding to the plate. The assembly leading to a reversible compass bearing.

It will be noted that, in the context of this last previous document, the locking by screwing of the plate relative to the blade is in no way able to meet the requirements of the user and, in particular, the carpenter who is required to affix this level of compass on its joinery.

In fact, screwing is a particularly long operation and has the drawback of involving a small screw whose manipulation is difficult and which is easy to lose.

To these problems is added that posed by the tools which the carpenter must call upon when assembling and adjusting all the fittings fitted to the leaf or frame of a door, window or the like. Indeed, it should be noted that this tooling must be reduced to the strict minimum and, preferably, to a single tool so that the time that should be allocated to this assembly and adjustment of the fittings can be reduced as much as possible. .

However, in most cases, the mounting and dismounting of the different parts making up a compass bearing requires the use of a tool or several tools different from those used for adjusting or mounting the other fittings fitted to the door. , window or the like.

The object of the present invention is to remedy all of the aforementioned drawbacks by proposing a compass bearing whose reversibility is not linked to disassembly followed by reassembly of the parts which constitute it, but to a simple adjustment made at by means of a standard tool which will be used during the various assembly and adjustment operations of the other fittings of the door, window or the like.

To this end, the invention, as characterized in the first claim, consists in creating a compass bearing for a tilt-and-turn window opening of doors, windows or the like, comprising an attached support on the internal face of the frame and a blade pivotally mounted on said support and having a square shape so as to define a wing, being inserted in the closed position of the door, window or the like, in the rebate of the latter, on the rear face of this wing being swivel mounted a plate at the free end of which is fixed a compass arm by means of a pivot, on the one hand the wing corresponding to the blade being provided on its upper and lower edge with a plug capable of being inserted in an opening arranged at the level from the underside of the housing constituting the pivot and, on the other hand, the plate being pivotally mounted on the rear face of the wing corresponding to the blade by means of rotation constituted by an eccentric whose rotation generates a vertical movement of said plate relative to said blade to cause the release of a plug from the opening in the pivot.

The advantages obtained thanks to the present invention consist essentially in that the compass bearing responds both to the problem of standardization of the parts at the manufacturing level and to the assembly requirements for the carpenter. More specifically, the manufacturer is able to produce and store a compass bearing intended for a specific use without the modification of this compass bearing for another use resulting in a loss of time for the carpenter or requiring tools. specific.

The present invention relates to a compass bearing 1 as shown in Figures 1 to 3, intended to ensure, more particularly, the high connection between the leaf 2 tilt-and-turn and the frame 3 of a door, window or the like 4.

More specifically, this compass bearing 1 comprises a support 5 ensuring its connection to said sleeping frame 3. Also, this support 5 has a fixing plate 6 applied on the internal face 7 of the rear upright 8 of this frame 3, more precisely, near the upper angle 8 formed by the latter. Note the presence of openings 10, arranged in this fixing plate 6 and serving for the passage to fixing members, such as screws, rivets or the like. In addition, this fixing plate 6 can be provided on its dorsal face 11, coming to bear on said rear upright 8, with two pins 12 fitting into openings made in the latter so as to improve the mechanical strength of the together.

This support 5 is further completed by two knuckles 13, 14 arranged in the same vertical alignment and located, substantially, at the ends 15, 16 of the fixing plate 6.

The compass bearing 1 also includes a blade 17 intended to cooperate, by means of a compass arm 18, with the leaf 2 of the door, window or the like. This blade 17 takes the form of a square comprising a wing 19 which is inserted, in the closed position of said door, window or the like, in the rebate 20 of the latter. The other wing 21 of the blade 17 is provided, at its front vertical edge, with a socket 22. The latter comes to be inserted between the two knuckles 13, 14 of the support 5. A pin 23 engaged in the the bore of said knuckles 13 and 14 and in the bore of the bush 22 ensures the pivoting connection of the blade 17 on the support 5.

The compass bearing 1 is completed by a pivot 24 made integral with the wing 19 of the blade 17 and coming to cooperate with the rear end 25 of the compass arm 18.

More specifically, this rear end 25 of said compass arm 18 is provided with a threaded endpiece 26 engaging in a bore 27 (see FIG. 4) of a housing 28 constituting said pivot 24. The free end 29 of this endpiece threaded 26 comes, moreover, to emerge from the opposite side 30 of the housing 28 and cooperates with a nut or the like so as to make said compass arm 18 of the pivot 24 integral. Such a configuration also allows the position to be adjusted. of the opening 2 relative to its dormant frame 3 by acting on the length of the threaded endpiece 26 introduced into said pivot 24.

According to a characteristic of the present invention, the compass bearing comprises means 32 capable of imparting a certain mobility, without disassembly, of the blade 17 relative to the compass arm 18, this to ensure the reversibility of said compass bearing 1 and, finally, authorize its assembly, indifferently to the right or to the left of the opening of a door, window or similar.

In fact, the main advantage provided by such means 32 is that the adaptation to a sash opening to the left of a pre-mounted compass bearing for use on the right, does not require, on the part of the operator, the disassembly of this compass bearing. Indeed, only the rotation of the blade 17 relative to the compass arm 18 is to be performed and this, using a standard tool.

According to a preferred embodiment of the present invention, these means 32 consist of a plate 33 pivotally mounted on the wing 19 of the blade 17, on this plate 33 being attached the pivot 24.

More specifically, said plate 33 comes to bear on the rear face 34, oriented in the direction of the rear upright 8 corresponding to the frame 3, of the wing 19 so that the free end 35 of said plate 33 is projecting relative to the upper edge 36 of the blade 17. On this free end 35 of the plate 33 can thus be attached the pivot 24 either by welding or other assembly methods.

Furthermore, rotation means 37 ensure the connection of said plate 33 at its opposite end 38, to the wing 19 corresponding to the blade 17 and, this, substantially in the horizontal median plane 39 of the latter.

Thus, by pivoting said blade 17 through 180 degrees relative to these means of rotation 37 which link it to the plate 33, the bearing of the compass 1 is given a structure suitable for mounting on the left whereas initially it was intended right mounting.

Note that the means 32 allowing this mobility of the blade 17 relative to the compass arm 18 and, more particularly, relative to the plate 33 are supplemented by rotation locking means 40 capable of ensuring the immobility of this blade 17 with respect to said audit compass arm 18 when their arrangement, one relative to the other, corresponds to the subsequent mounting of the compass bearing 1 on a door, window or the like.

Preferably, such blocking means 40 consist of plugs 41, 42, attached to the upper edge 36 and lower edge 43 of the wing 19, one of these plugs, depending on the position of the blade 17 relative to the compass arm 18, coming to be inserted into an opening 44 provided for this purpose, at the level of the lower face 45 of the housing 28 constituting the pivot 24. Therefore, to allow the rotation of the plate 33 relative to the wing 19 corresponding to blade 17, it is initially necessary to disengage the housing 28 from one or the other plug 41, 42. This clearance, corresponding to a vertical displacement of the plate 33 and, finally, of the pivot 24 relative to the blade 17, is obtained, according to the invention, as a result of an action, by means of a standard tool, on the rotation means 37 ensuring the connection of said plate 33 to the wing 19 of blade 17.

Advantageously, these means of rotation 37 feel constituted by an eccentric 46 which can be maneuvered by means of a standard tool such as a screwdriver, a hexagon wrench or the like. In fact, this eccentric 46 must be adapted to the tool most commonly used for mounting and adjusting all of the fitting elements disposed on the leaf and the frame of a door, window or the like.

In all cases and whatever the tool used, the rotation of this eccentric in a given direction causes the vertical displacement of the plate 33 relative to the blade 17 from which results the release, for example, of the plug 41 of the opening 44 present in the pivot 24. It then suffices to control, the rotation of said plate 33 by an angle of approximately 180 ° and then to intervene again on the eccentric 46 in order to authorize the pivot 24 to be positioned on the right of the card 42.

A final rotation of this eccentric 46 conferring a vertical displacement on the plate 33 ensures the engagement of said plug 32 in the opening 44 present in the housing 28 thereby immobilizing the compass arm 18 relative to the blade 17 .

As illustrated in FIG. 4, the opening 44, serving for the passage of the plugs 41, 42, may correspond to a milling carried out at the rear face 30 of the housing 28, this milling opening onto the upper face 47 and onto the underside 45 of the latter. In fact, such a configuration makes it possible to give the pivot 24 a structure that is substantially symmetrical with respect to a horizontal median plane allowing it to be mounted by riveting on the plate 33, indifferently in one direction or another.

It will be noted, however, that the milling solution, for obtaining a symmetrical structure of a pivot 24 provided with openings 44, is not unique and it can be envisaged to produce this pivot 24, either by stamping , or by molding, while obtaining an identical design.

In addition, it is worth noting the particularity of the plugs 41, 42. Indeed, these are slightly curved at their end so as not to constitute an obstacle to the passage of the threaded end piece 26 of the compass arm 18 in the bore 27 of the housing 28.

As visible in Figure 4, the housing 28 also has, at its end opposite the plate 33, a crimp 48 forming a boss capable of being inserted in a groove 50 formed in a flat 49 arranged at the end rear 25 of the compass arm 18 and, more precisely, at the level of the threaded end piece 26. This characteristic makes it possible to prevent said compass arm 18 from being released, unexpectedly, from its pivot 24 during the adjustments of the opening and this, by limiting this adjustment range and, finally, the amplitude of the axial displacement which it is possible to impart to the compass arm 18 relative to the pivot 24. In addition, it should be noted that such crimping prevents the rotation of the threaded end piece 26 of this compass arm 18 relative to the pivot 24, thereby preventing these parts from coming apart from one another during their storage or during their assembly.

Apart from the main advantage of an easy adaptation of the compass bearing 1 to the opening of a door, window or the like opening on the right or on the left, the present invention contributes, in addition, to a better mechanical resistance. of this compass bearing 1. Indeed, the superposition of the plate 33 on the wing 19 corresponding to the blade 17, gives the assembly a better resistance to torsion which can be a significant advantage, in particular when the opening has a certain weight.

Furthermore, this mechanical strength of the assembly does not go against the requirements of mounting a compass bearing on the opening and the frame of a door or window. Indeed, it has been found, at the level of known compass bearings, that their rigidity constitutes a hindrance to this mounting and, ultimately, was at the origin of a considerable loss of time.

In fact, the present invention makes it possible to remedy this problem linked to the general rigidity of the compass bearing, by allowing a certain mobility, during assembly, of the compass arm 18 relative to the blade 17 with which it is associated, and, this, by intervening, simply, on the eccentric 46. Once the assembly carried out, it is enough to act, again, on this eccentric so as to proceed to the suppression of this mobility.
