The retainer has a pivot ball joint (11) with a convex engagement surface above which is a contact surface of the movable frame member. The ball joint has side stop faces to limit the pivoting.

Description

The invention relates to a corner support for a door, window or analog defined by a sleeping frame on which is mounted tilt-and-turn manner, an opening frame, said angle support comprising a fixed part designed to be secured to said frame dormant and able to cooperate, through an articulation means, with a movable part capable of being made integral with said chassis opening. See for example DE 28 26 945 B.

The present invention relates to the field of hardware building and relates more specifically to a fitting hinge, of the angle support type, for opening type tilt and turn.

There are already a number of corner supports for door, window or the like corresponding to the above description.

Thus such a corner support comprises, on the one hand, a fixed part made integral with the sleeping frame of this door or window and on the other hand, a mobile part which is attached to the chassis opening.

Such a corner support has the particularity of allowing said frame opening, both to pivot around an axis vertical joint for a French type opening and, on the other hand, to swing around an axis of rotation horizontal, materialized, substantially, by the lower crossmember of this opening frame, when it opens by folding down.

Also, the fixed part and the mobile part of this corner support cooperate by means of articulation means allowing these two movements. More particularly, as the case may be, the part mobile or the fixed part receives a ball joint provided capable of being engaged in a well of adapted shape, respectively, at level of the fixed part or of the mobile part. Unless oversize said ball, it offers, as as a means of articulation, a coupling at engagement height reduced, which can lead to an unexpected drop in the chassis opening in relation to the sleeping frame, in particular in the event of improper handling of the door or window.

In addition, the reassembly of the chassis opening onto its sleeping frame by engagement of said ball joint of the mobile part of the support of angle in the well of the fixed bet is not made difficulty, insofar as it is convenient for the operator to both support, during this maneuver, said chassis opening and aiming just in due to a tight fit of this well relative to the patella.

If there are currently anti-take-off devices, they are rarely suitable for tilt-and-turn windows, but for simply pivoting openings.

The present invention is therefore intended to provide a solution to the aforementioned drawbacks.

To this end, the present invention relates to a corner support for door, window or the like defined by a sleeping frame on which is tilt-and-turn mounted, an opening frame, said corner support comprising a fixed part intended to be secured to said sleeping frame and able to cooperate, through a articulation means, with a movable part capable of being rendered integral with said opening frame, characterized in that said articulation means is constituted by a defined toggle, at level of the fixed part, by a convex bearing surface above which is able to move in sliding a surface support corresponding to the mobile part, said articulation means being supplemented by means capable of limiting the amplitude of the sliding of the two surfaces one on the other appearing under shape of a section of axis emerging from said bearing surface corresponding to the mobile part and coming to be inserted in a well reception with frustoconical mouth formed at the surface convex support of the fixed part.

According to an additional characteristic, said receiving well presents, at its bottom, a room, accessible through a throttle, and intended for the reception of a ball joint of blocking section, on the one hand, greater than that corresponding to this constriction and, on the other hand, at most equal to that of the bedroom.

Advantageously, the fixed part has the form of a socket, axis coincides with the pivot axis of the opening frame, for the reception of an insert in which is formed the mouth well frustoconical, this insert ending in the upper part with a support flange coming to rest on said socket and the face of which upper defines the convex bearing surface.

Another characteristic concerns the fact that the movable part is configured as a socket with a bore inside which is engaged an insert defining, at its face oriented in direction of the fixed part, said bearing surface of the part mobile.

In fact, this insert is slidably mounted in the bore of the sleeve of the movable part and comes to cooperate, in its part upper, with adjustment means defined by a screw adjustment whose thread cooperates with a threaded portion of said bore of the sleeve of the movable part.

According to another characteristic, said corresponding axis section by means of articulation, goes right through the insert engaged in the sleeve of the movable part and comprises, in its part engaged in the bore of this sleeve, a flange likely to be supported, on the one hand, on this insert and, on the other hand, against a shoulder formed in this bore of said sleeve of the moving part.

As regards the screw of the adjustment means, this is designed able to act on the axis section, more particularly, on its end, engaged in socket of the movable part.

The advantages which flow from the present invention consist of what the means provided capable of limiting the amplitude of the sliding of the two surfaces relative to each other, in the form of a axis section, provide a coupling, part movable relative to the fixed part of this corner support, more important. Also effectively supported by means coming to block at the bottom of its receiving well, this section of axis thus avoids, any risk of unexpected drop of the opening frame.

Its voluntary withdrawal remains, however possible, what is more with great ease, as will become apparent from the description who will follow.

The invention will be better understood on reading the following description relating to an embodiment illustrated in the accompanying drawings.

• FIG. 5 again corresponds to a view similar to FIGS. 2 to 4, and corresponds to an angle support after adjustment in height of this opening frame relative to the sleeping frame.

As shown in the figures in the accompanying drawings, the present invention relates to a corner support 1 for door, window or the like 2 connecting, at the bottom, the chassis opening 3 of this door or window 2 to its sleeping frame 4.

This corner support 1 has the function of authorizing an opening by pivoting about a vertical axis 5 of this opening frame 3 by report to said frame 4, as well as an opening by folding consisting of a rotation of this opening frame 3 around an axis horizontal 6 materialized, substantially, by the lower cross member 7 of said opening frame 3.

Thus, this angle support 1 consists of a fixed part 8 made secured to said sleeping frame 4 and to an attached movable part 9 to the opening frame 3, this fixed part 8 and the mobile part 9 coming to cooperate through a hinge means 10 provided for authorize the two movements recalled above.

Advantageously, said articulation means 10 is constituted by a toggle 11 defined, on the one hand, at the level of said fixed part 8, by a support surface 12 of convex shape above which is able to move in sliding a support surface 13 corresponding to the mobile part 9.

This articulation means 10 is, again, supplemented by means 14 able to limit the amplitude of the sliding of the two surfaces 12, 13 one 13 on the other 12, in the form of a section of axis 15 emerging of said bearing surface 13 of the movable part 9 and coming fit into a receiving well 16 with frustoconical mouth 17 formed at the convex bearing surface 12 of the fixed part 8.

More particularly, the fixed part 8 has a similar shape to a socket 18, of axis coinciding with the pivot axis 5 of the opening frame 3, for receiving an insert 19 in which is formed this well 16 with frustoconical mouth 17, this insert 19 is ending, in the upper part, with a support flange 20 coming rest on this socket 18 and whose upper face defines the convex bearing surface 12.

Note that the frustoconical shape of the mouth 17 of this well reception 16, not only, allows, in cooperation with said axis section 15, to limit the sliding amplitude of said bearing surfaces 12, 13 one on top of the other 12, but, in addition, greatly folding the frame opening 3 on its frame sleeping 4.

As for said movable part 9, it is also configured to similar to a socket 21 having an axis bore 22 combined with the pivot axis 5.

In the lower part 23 of this socket 21 engaging a insert 24 which, at its face 25 opposite the fixed part 8, defines said bearing surface 13. Note that this face 25 of insert 24 can, here again, be in the form of a flange support extending under the sleeve 21 of the movable part 9.

As for said bearing surface 13, it can be either flat or of concave shape substantially adjusted to the convex shape of the bearing surface 12 corresponding to the fixed part 8.

Furthermore, the insert 24 is advantageously mounted to slide, axially, in the bore 22 of the sleeve 21 and cooperates, in its upper part 26, with defined adjustment means 27, substantially, by an adjusting screw 28 whose thread comes cooperate with a threaded portion in the bore 22 of this socket 21.

The operating principle is that by acting on this adjusting screw 28, an axial displacement is created of the insert 24 relative to the sleeve 21. Knowing that said insert 24 cooperates with the convex bearing surface 12 of the fixed part 8 then that the sleeve 21 is made integral with the opening frame 3, it results in a height adjustment of the latter 3 relative to the frame dormant 4. The principle of this adjustment will be taken up further in the description.

Preferably, in the bottom 29 of the receiving well 16, is defined a chamber 30, accessible through a throttle 31, for the reception of a locking ball joint 32 extending, at its end 33, the axis section 15.

More particularly, this locking ball joint 32 is of section greater than that delimited by the throttle 31, while being at more equal to that 34 of room 30.

According to a first embodiment not shown in the drawings, the axis section 15 can be an integral part of the insert 24. In this case, in the upper part 26 of this insert 24 comes to cooperate directly with the adjusting means 27 in the form of a screw setting 28.

However, insofar as the bearing surfaces 12, 13 are, preferably defined in a material with a low coefficient of friction, in particular in a synthetic material, the axis section 20 can be defined in another material capable of absorb greater mechanical stress, in particular metallic, and can come, as shown in Figures 2 to 5, cross, on both sides, the insert 24 which then comprises a opening 35 of section adjusted for this purpose.

In this case, this section of axis 15 comprises in its part 36, engaged in the bore 22 of the sleeve 21, by a flange 37 able to bear on the upper part 26 of the insert 24.

Thus, the adjusting screw 28 acts, not on the insert 24, but on the axis section 15.

Within the framework of such a conception and starting from the principle that the axis section 15 is immobilized, in its lower part, in the receiving well 16 through its blocking ball 32, the unhooking of the opening frame 3 relative to the sleeping frame 4 intervenes through the clearance of the socket 21 corresponding to the movable part 9 relative to the upper bet 36 of this axis section 15.

It is obvious that the engagement length of the upper part 36 of this section of axis 15 in said socket 21 can also be important as one might wish. In particular, if the screw adjustment 28 can be extended to rest on the flange 37 ending the axis section 15 at its upper end, as visible, for example, in Figure 2, beyond this flange 37, this section of axis 15 can be further extended until it reaches an adjustment screw 28 placed higher in the socket 21, or even simply shorter.

This obviously avoids an unexpected drop in the chassis opening 3.

Furthermore, in the bore 22 of the sleeve 21 is formed a shoulder 39 against which is able to bear the flange 37 of the axis section 15. This position is, more particularly, occupied by this section of axis 15 prior to mounting the chassis opening 3 on the frame 4, as shown in the figure 3.

Finally, this shoulder 39 and, therefore, the position of the axis section 15, before this mounting is determined so that the end 33 of said axis section 15 can dive into the receiving well 16 and that the bearing surfaces 12 and 13, respectively, of the fixed part 8 and of the mobile part 9, come to cooperate with each other, without that the locking ball 32 is inserted into the chamber 30 through the throttle 31.

Finally, this allows easy pre-assembly of this opening frame 3 on the frame 4, knowing that once this pre-assembly has been carried out, we just act on the adjustment means 27, in particular on the adjusting screw 28, to force the locking ball 32 to pass to the throttle 31.

On this subject, it should be noted that, as a first step during this adjustment, the opening frame 3 lifts up to make up the backlash with respect to the sleeping frame 4. Then, once this opening frame 3 immobilized, the adjusting screw 28 actually comes to force the engagement of said ball joint blocking 32 in chamber 30.

Note that once this passage through the throttle 31 defeated by said locking ball 32, the axis section 15 falls back of itself in support, by means of its flange 37, on insert 24 as visible in FIG. 4. This results in a sagging of the opening frame 3 relative to the sleeping frame 4.

Then, continuing to act on the adjusting screw 28, it comes again take support on said axis section 15 and, therefore, on said insert 24 through the flange 37 of the latter, allowing, in the end, to adjust, in height, the movable part 9 relative to the fixed part 8 of this angle support 1, therefore, that of the chassis opening 3 relative to the sleeping frame 4. This has been made visible in Figure 5 where we see a gap 40 between the socket 21 and the support flange extending under the latter of the insert 24.

As is apparent from the above description, the present invention effectively responds to the problem, not only of the unexpected unstuck of a corner support of a door or window tilt-and-turn, but, in addition, that of mounting a chassis opening such a door or window on its sleeping frame, handling which, until now, required very great dexterity.
