Abstract

The corner retainer (1) has a fixed bracket (8) fixed to the lower cross member to co-operate with a movable frame section (9) which carries the retainer and which is fixed to the opening frame. 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 the like.

  defined by a sleeping frame on which is oscillatingly mounted, an opening frame, said angle support comprising a fixed part made integral with said sleeping frame and able to cooperate, through an articulation means, with a mobile part contained in said corner support and which is rendered

integral with said opening frame.

  The present invention relates to the field of building hardware and relates, more particularly, to a hinge fitting, of the angle support type, for an opening of the tilt-and-turn type. There are already a number of supports

  angle for door, window or the like corresponding to the description

  above. 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 opening frame. Such a corner support has the particularity of allowing said opening frame, at the same time, to pivot around a vertical articulation axis for a French type opening and, on the other hand, to swing around. a horizontal axis of rotation, materialized, substantially, by the lower cross member of

  this opening frame, when it opens by folding down.

  Also, the fixed part and the mobile part of this angle support cooperate by means of articulation means allowing these two movements. More particularly, as the case may be, the movable part or the fixed part receives a ball joint provided capable of being engaged in a well of adapted shape made, respectively, at

  level of the fixed part or of the mobile part.

  Unless oversizing said ball joint, it offers, as a means of articulation, a coupling with reduced engagement height, which can cause the unhooked unhooking of the opening frame relative to the sleeping frame, in particular

  improper handling of the door or window.

2 2808045

  Furthermore, reassembly of the chassis opening on its dormant frame by engagement of said ball joint of the movable part of the angle support in the well of the fixed bet is not difficult, insofar as it is suitable for the operator, at the same time, to support, during this maneuver, said opening frame and to aim just because of a tight adjustment of this well relative to

at the kneecap.

  If there are currently anti-

  they are rarely adapted to swing openings

  casement, but with simply pivoting sashes.

  The present invention is therefore intended to

  to provide a solution to the aforementioned drawbacks.

  To this end, the present invention relates to a corner support for a 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 made integral with said sleeping frame and able to cooperate, through an articulation means, with a movable part which comprises said angle support and which is made integral with said opening frame, characterized in that said articulation means is constituted by a toggle defined, at the level of the fixed part, by a convex bearing surface above which is able to move in sliding a bearing surface corresponding to the movable part, said articulation means being supplemented by means capable of limiting the amplitude of the sliding of the two surfaces one over the other in the form of a section of axis emerging from said bearing surface corresponding to the movable part and v by fitting into a receiving well with a frusto-conical mouth

  at the convex bearing surface of the fixed part.

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

that of the bedroom.

3 2808045

  Advantageously, the fixed part has the form of a socket, of axis coincident with the pivot axis of the opening frame, for the reception of an insert in which is formed the well with frustoconical mouth, this insert ending, in upper part, by a support flange coming to rest on said socket

  and the upper face of which defines the convex bearing surface.

  Another characteristic relates to the fact that the mobile part is configured as a bushing comprising a bore inside which an insert is engaged defining, at its face oriented towards the fixed part, said bearing surface of the mobile part . In fact, this insert is slidably mounted in the bore of the sleeve of the movable part and comes to cooperate, in its upper part, with adjustment means defined by an adjustment screw whose thread cooperates with a tapped portion of said

  bore of the sleeve of the mobile part.

  According to another characteristic, said section of axis corresponding to the articulation means, passes 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 capable of bearing, on the one hand, on this insert and, on the other hand, against a shoulder formed in this bore of

said sleeve of the movable part.

  As regards the screw of the adjustment means, it is designed capable of acting on the axis section, more particularly, on its end, engaged in the bushing of the mobile part. The advantages which result from the present invention consist in that that the means provided capable of limiting the amplitude of the sliding of the two surfaces relative to one another, in the form of a section of axis, make it possible to provide a coupling, of the movable part with respect to the part fixed of this corner support, more important. In addition, effectively supported by means coming to block at the bottom of its receiving well, this section of axis avoids,

  thus, any risk of unexpected unhooking of the opening frame.

  Its voluntary detachment remains, however possible, what is more with great ease, as will emerge from the

description which follows.

  In this regard, other objects and advantages of the present invention

  will appear in the context of this description relating to a

  embodiment which is given only by way of indicative example

and not limiting.

  Understanding this description will be facilitated by

  referring to the attached drawings in which: - Figure 1 shows, schematically and partially, an opening frame of tilt-and-turn type, connected to a frame by means of an angle support according to the invention ; - Figure 2 is a schematic representation in section of the movable part and the fixed part of this angle support according to the invention; - Figure 3 is a representation similar to Figure 3 illustrating the cooperation of the articulation means in the initial phase of mounting a frame opening on its sleeping frame; - Figure 4 corresponds to a view similar to Figures 2 and 3 above after full engagement of the axis section of the hinge means in its receiving well; - Figure 5 corresponds, again, to a view similar to Figures 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 of the accompanying drawings, the present invention relates to a corner support 1 for door, window or the like 2 connecting, in the lower part, the frame

  opening 3 of this door or window 2 to its sleeping frame 4.

  This angle support 1 has the function of authorizing an opening by pivoting about a vertical axis 5 of this opening frame 3 relative to said sleeping frame 4, as well as a folding opening consisting of a rotation of this opening frame 3 around a horizontal axis 6 materialized, substantially, by the crosspiece

  lower 7 of said opening frame 3.

  Thus, this angle support 1 consists of a fixed part 8 made integral with said sleeping frame 4 and a movable part 9

2808045

  attached to the opening frame 3, this fixed part 8 and the movable part 9 coming to cooperate through an articulation means 10

  intended to 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 surface

  support 13 corresponding to the movable part 9.

  This articulation means 10 is, further, supplemented by means 14 capable of limiting the amplitude of the sliding of the two surfaces 12, 13, one 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 to be inserted in a receiving well 16 with frustoconical mouth 17 formed at the level of the convex bearing surface 12 of

the fixed part 8.

  More particularly, the fixed part 8 has a shape similar to a socket 18, of axis coincident with the pivot axis 5 of the opening frame 3, for the reception of an insert 19 in which is formed this well 16 with frustoconical mouth 17, this insert 19 ending, in the upper part, with a support flange 20 coming to 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 receiving well 16, not only, allows, in cooperation with said section of axis 15, to limit the sliding amplitude of said bearing surfaces 12, 13 l ' one 13 on the other 12, but, in addition, greatly folding the chassis opening 3 on its frame

sleeping 4.

  As for said movable part 9, it is also configured similarly to a socket 21 having a bore

  22 of axis coinciding with the pivot axis 5.

  In the lower part 23 of this socket 21 engaging an insert 24 which, at its face 25 facing the fixed part 8, defines said bearing surface 13. Note that this face 25 of the insert Again, it can be in the form of a

  support flange extending under the bushing 21 of the movable part 9.

6 2808045

  As for said bearing surface 13, it can be either flat or concave in 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 adjustment means 27 defined, substantially, by an adjustment screw. 28, the thread of which cooperates with a threaded portion in the bore 22

of this socket 21.

  The operating principle consists in that by acting on this adjusting screw 28, an axial displacement of the insert 24 is created relative to the sleeve 21. Knowing that said insert 24 cooperates with the convex bearing surface 12 of the fixed part 8 while the sleeve 21 is made integral with the opening frame 3, this results in a height adjustment of the latter 3 relative to the sleeping frame 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 greater cross section than that delimited by the throttle 31, while

  being at most equal to that of chamber 30.

  According to a first embodiment not shown in the drawings, the axis section 15 may form 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 adjustment means 27 cents

shape of an adjusting screw 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 can, for its part, be defined in another material capable of withstanding greater mechanical stresses, in particular metallic, and may come, as shown in FIGS. 2 to 5,

7 2808045

  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 design and starting from the principle that the section of axis 15 is immobilized, in its lower part, in the receiving well 16 through its locking ball joint 32, the recess of the opening frame 3 relative to the frame 4 intervenes through the clearance of the sleeve 21 corresponding to the movable part 9 relative to the upper part 36 of this

axis section 15.

  It is obvious that the length of engagement of the upper part 36 of this section of axis 15 in said bushing 21 can be as large as may be desired. In particular, if the adjusting screw 28 can be extended to bear on the flange 37 terminating the section of axis 15 at its end

  upper, as visible, by way of example, in FIG. 2, above

  beyond this flange 37, this section of axis 15 can be further extended until reaching 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 provided 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 axis section 15 prior to mounting the opening frame 3 on the sleeping 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 plunge into the receiving well 16 and that the surfaces of support 12 and 13, respectively, of the fixed part 8 and the movable part 9, come to cooperate with

8 2808045

  the other, without the locking ball 32 being inserted into

  the chamber 30 through the throttle 31.

  Finally, this allows an easy pre-assembly of this opening frame 3 on the sleeping frame 4, knowing that once this pre-assembly has been carried out, one comes to act on the adjusting means 27, in particular on the adjusting screw 28, to force the patella of

  blocking 32 to pass through the throttle 31.

  It should be noted, in this regard, that, in a first step during this adjustment, the opening frame 3 lifts up to catch up with the rebate clearance relative to the sleeping frame 4. Then, once this opening frame 3 immobilized, the adjusting screw 28 effectively forces 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 section of axis 15 falls by itself in support, via its flange 37, on the insert 24 as shown in Figure 4. This results in a

  sagging of the opening frame 3 relative to the sleeping frame 4.

  Then, while continuing to act on the adjustment screw 28, the latter again comes to bear on said section of axis 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 opening frame 3 relative to the sleeping frame 4. This has been made visible in FIG. 5 o we see a gap 40 between the sleeve 21 and the support flange extending under the latter of

insert 24.

  As is apparent from the above description, the present

  invention effectively responds to the problem, not only of the unexpected unhinging of a corner support of an oscillating door or window, but, moreover, that of mounting an opening frame of such a door or window on its sleeping frame, manipulation which, until now, required a very great dexterity. Although the invention has been described with reference to a particular embodiment, it is understood that it is not there

9 2808045

  in no way limited and that various modifications of shapes, materials and combinations of these various elements can be made thereto, without

  for this to move away from the framework and the spirit of the invention.
