HITTING A CORNER CAMP FOR DOORS, WINDOWS OR SUCH A THING

The invention relates to a corner support for doors, windows or the like defined by a frame to which is mounted a turn-tilt, an opening frame, said mounting bracket having a fixed part adapted to be secured to said fixed frame and adapted to cooperate, through a hinge means, with a movable portion adapted to be secured to said frame opening. See for example 28, 26 945 b..

The present invention relates to the field of hardware of the building and relates, more particularly, to a hinge bracket, support angle type, sash tilting window.

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

Thus such a corner support includes, on the one hand, a fixed part made integral with the outer frame of the door or window and on the other hand, a movable part which, it, is reported at the casement.

Such a support angle has the particularity to allow said frame opening, both, to pivot about a vertical hinge axis for a French-like opening and, on the other hand, swing about a horizontal axis of rotation, materialized, substantially, by the lower cross member of the opening sash, when it opens in flap.

Also, the fixed part and the movable part of the corner support cooperate through an articulation means allowing these two motions. More particularly, as the case may be, the movable portion or the stationary portion receives a ball provided suitable to be engaged in a well adapted form provided, respectively, at the fixed portion or the movable portion. Has less oversized ball, it offers, as hinge means, a clutch engagement height reduced, which can lead to unintended the shoulder of the casement relative to the fixed frame, in particular due to inappropriate appropriate of the door or window.

Furthermore, reassembly of the casement window frame by frame on its engagement of said ball of the movable portion of the mounting bracket in the well of the pair fixed is not difficulty, inasmuch as it is convenient for the operator, both, supporting, during this maneuver, said casement and aim just because of tight fit of this well with respect to the patella.

If there is at present devices [...]-to-unhinging, they are rarely suitable for tilt and doors, but to simply pivoting of the doors.

The present invention wants, therefore, to help provide a solution to the above drawbacks.

To this end, the present invention provides a corner support for doors, windows or the like defined by a frame to which is mounted a turn-tilt, an opening frame, said mounting bracket having a fixed part adapted to be secured to said fixed frame and adapted to cooperate, through a hinge means, with a movable portion adapted to be secured to said frame opening, characterized in that said articulation means is constituted by a defined socket, at the fixed portion, by a convex bearing surface above which is capable of movement in sliding a contact surface corresponding to the movable portion, said hinge means being completed by means adapted to limit the magnitude of sliding of the two surfaces on each other in the form of an axle section emerging from said bearing surface corresponding to the movable portion and engages in a receiving pit to truncated end provided at the convex bearing surface of the fixed portion.

According to an additional characteristic, said receiving pit has, at its bottom, a chamber, accessible through a throttle, and for receiving a ball section clamp, on the one hand, greater than that corresponding to the restriction and, on the other hand, at most equal to that of the chamber.

Advantageously, the fixed part includes a sleeve, of axis coincident with the pivot axis of the casement, for locating an insert in which is formed the well to truncated end, the insert terminating, in the upper part, by supporting flange resting on said sleeve and whose upper surface to form the convex bearing surface.

A further feature relates to the fact that the movable portion is configured in a bushing including a bore into which is inserted an insert defining, at its face oriented towards the fixed part, said bearing surface of the movable part.

In fact, this insert is slidably mounted in the bore of the sleeve of the movable portion and cooperate, in its upper part, with adjusting means defined by an adjustment screw threadedly engages a threaded portion of said bore of the bushing of the movable part.

According to another feature, said pin segment corresponding to the hinge means, comes through, right, the insert inserted in the socket of the movable portion and includes, at its portion inserted in the bore of this bushing, a flange capable of, on the one hand, this insert and, on the other hand, against a shoulder formed in the bore of said bushing of the movable portion.

As to the screw of the adjusting means, it is designed capable of acting the axle section, more particularly, on its end, engaged in bushing of the movable portion.

The advantages of the present invention consists in that the means capable of limiting the magnitude of sliding of the two surfaces relative to each other, in the form of an axle section, for providing a coupling, the movable portion relative to the stationary part of said corner support, larger. Further shouldered efficiently by means to lock at the bottom of its reception well, this spindle length avoids, thus, any unintended setback of the casement.

Its shoulder voluntary remains, however can, moreover with great ease, as this will be apparent from the description which will follow.

The invention will be better understood upon reading the description which will follow relating to an embodiment illustrated in the accompanying drawings.

• figure 1 represents, schematically and partially, an opening frame tilting window, connected to a frame via a mounting bracket according to the invention;
• figure 2 is a schematic and sectional of the movable part and the stationary part of said angle support according to the invention;
• figure 3 is a representation similar to Figure 3 illustrating the cooperation of the hinge means in initial phase of mounting an opening frame on its frame;
• figure 4 corresponds to a view similar to Figures 2 and 3 become fully engaged after the preceding spindle length of the articulating means in its receiving well;
• figure 5 corresponds, again, to a similar view in Figures 2 to 4, and corresponds to an angle bracket after height adjustment of the opening sash relative to the window frame.

As shown in the Figures of the drawings in the appendix, the present invention provides a corner frame 1 for door, window or the like 2 from connecting, in the lower part, the casement 3 of this door or window 2 at its outer frame 4.

This support angle 1 functions to authorize an opening by pivoting about a vertical axis 5 of the opening sash 3 relative to said fixed frame 4, and an opening in lid consisting of a rotation of the opening sash 3 about a horizontal axis 6 materialized, substantially, by the lower cross member of said frame opening 7 3.

Thus, the corner support 1 consists of a fixed part 8 secured to said fixed frame 4 and a movable part 9 relative to the casement 3, this fixed part and the movable part 9 8 interacting through a hinge means 10 provided for authorizing the two motions recalled above.

Advantageously, said hinge means 10 is constituted by a toggle 11 defined, on the one hand, at said fixed part 8, by a bearing surface 12 of convex shape over which is adapted to move in sliding a bearing surface 13 corresponding to the movable part 9.

This hinge means 10 is, still, complete with 14 capable of limiting the magnitude of sliding of the two surfaces 12, 13 a 12 13 on the other, in the form of an axle section 15 emerging from said bearing surface 13 of the movable part 9 and engages in a receiving shaft 16 to truncated end 17 provided at the convex bearing surface of the fixed portion 12 8.

More particularly, the fixed part 8 is formed similarly to a bushing 18, of axis coincident with the pivot axis 5 of the casement 3, for receiving an insert 19 is provided wherein the well 16 to truncated end 17, this insert 19 terminating, in the upper part, by supporting flange 20 resting on the sleeve 18 and has its upper face defined the curved bearing surface 12.

It should be noted that the frustoconical shape of the mouth 17 of the receiving shaft 16, not only, allows, in cooperation with said axle section 15, limit the extent of sliding of said bearing surfaces 12, 13 a 12 13 on the other, but, further, easy greatly [...] 3 of the casement window frame on its 4.

With regard to said movable part 9, it is configured, it also, similarly to a socket 21 having a bore 22 of axis coincident with the pivot axis 5.

In the lower part 23 of this sleeve 21 which engages an insert 24 which, at its face 25 facing the fixed part 8, defines said bearing surface 13. It should be noted that this face 25 of the insert 24 may, again, be in the form of a supporting flange extending under the sleeve 21 of the movable part 9.

With respect to said supporting surface 13, it may be, is planar, concave shaped is substantially adjusted to the convex shape of the contact surface 12 corresponding to the fixed portion 8.

In addition, the insert 24 is, advantageously, slidably mounted, axially, in the bore 22 of the sleeve 21 and engages, in its upper part 26, with adjusting means 27 defined, substantially, by an adjusting screw 28 threadedly engages with a threaded portion in the bore 22 of this bushing 21.

The principle of operation is that by acting on the adjusting screw 28, just been create axial movement of the insert 24 with respect to the bushing 21. Wherein said insert 24 cooperates with the convex bearing surface of the fixed portion 12 8 as the socket 21 is made integral with the casement 3, this results in a vertical adjustment of the latter 3 relative to the fixed frame 4. the principle of this adjustment will be resumed foremost in the description.

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

More particularly, the locking ball 32 is larger in section than delimited by the throat 31, while being at most equal to that of the chamber 34 30.

According to a first embodiment not shown in the drawings, the axle section 15 may be integrally formed with the insert 24. In this case, in the upper portion 26 of the insert 24 interacts directly with the setting means 27 in the form of an adjusting screw 28.

However, since the bearing surfaces 12, 13 are, preferably, defined in a material with a low coefficient of friction, in particular a synthetic material, the axle section 20 can, in turn, be defined as a material likely to absorb mechanical stresses, in particular metallic, and can engage, as shown in Figures 2 to 5, pass through, on either hand, the insert 24 has, then, an opening 35 section adjusted for this purpose.

In this case, the shaft section 15 has in its portion 36, 22 inserted in the bore of the sleeve 21, by a flange 37 capable of on the top 26 of the insert 24.

Thus, the adjusting screw 28 comes to act, not on the insert 24, but on the axle section 15.

In the context of such a design and assuming that the axle section 15 is immobilized, in its lower part, in the receiving shaft 16 through its locking ball 32, the shoulder of the casement 3 the wing 4 occurs through the clearance of the bushing 21 corresponding to the movable part 9 relative to the upper part 36 of the axle section 15.

It is obvious that the length of engagement of the top portion 36 of the axle section 15 in said socket 21 may be as large as it can be want. In particular, if the adjustment screw 28 can be extended to bear against the flange 37 terminating the axle section 15 at its upper end, as seen, for example, in Figure 2, beyond the flange 37, this axle section 15 may still be extended until it reaches an adjustment screw 28 placed higher in the sleeve 21, or even merely shorter.

This avoids, of course, a setback from unexpectedly casement 3.

Furthermore, in the bore 22 of the sleeve 21 is provided for a shoulder 39 against which is adapted to the flange 37 of the spindle length 15. This position is, in particular, occupied by this pin segment 15 prior to mounting of the casement 3 on the outer frame 4, as shown in Figure 3.

Finally, this shoulder 39 and, therefore, the position of the spindle length 15, before this circuit is determined so that the end 33 of said pin segment 15 can dip into the receiving well 16 and that the bearing surfaces 12 and 13, respectively, of the fixed part and the movable part 8 9, move into engagement with each other, without blocking the ball 32 does is inserted in the chamber 30 through the throat 31.

Finally, this allows easy preassembly of the opening sash 3 on the outer frame 4, being once this preassembly performed, which acts on the adjusting means 27, in particular on the adjusting screw 28, for forcing the locking ball 32 to pass through the constriction 31.

It should be noted, in this connection, that, in a first step in this setting, the casement 3 raised to take up the slack in the fillister the wing 4. then, once the opening sash 3 immobilized, the adjustment screw 28 comes, actually, forcing engagement of said locking ball 32 in the chamber 30.

It should be noted that once this passage through the throat 31 overcome by said locking ball 32, the axle section 15 falls of itself in abutment, via its flange 37, on the insert 24 as seen in Figure 4. this results in a collapse of the casement 3 the wing 4.

Then, by continuing to act on the adjusting screw 28, it is coming again on said axle section 15 and, therefore, on said insert 24 through the flange 37 thereof, for, ultimately, adjust, in height, the movable part 9 with respect to the fixed part 8 of the support angle 1, thus, that of the casement 3 the wing 4. this was made visible in Figure 5 vindications a gap 40 between the sleeve 21 and the support flange extending under the latter of the insert 24.

As apparent from the above description, the present invention comes effective response, not only, of the unintentional unhinging of an angle bracket of a door or window tilt-and-turn, but, further, to that of the mounting of an opening frame such a door or window on its frame, handling which, until now, had a very high dexterity.
