DESCRIPTION

  The present invention relates to the building sector, and more particularly to the fixing of elements or accessories to hollow structures, in particular profiles of opening frames, frames or the like, and relates to a hollow profile provided with '' at least one improved fixing area. It is often necessary to fix on hollow sections with thin walls and with several chambers parts or accessories ensuring a function in relation to the device or the structure integrating said sections. This is particularly the case for the fittings of a door or window to be secured to the profiled frames of the opening

  and / or frames, if necessary by being mounted in suitable grooves.

  This joining is carried out by means of a plurality of screws which pierce, by engaging therein, the material of the corresponding wall of the

profile.

  It turned out, however, in practice, that such a method of fixing did not guarantee a sufficiently rigid and resistant connection, greatly weakened the wall concerned and could lead to deterioration of the latter, in the event of effort. intense or brutal, by tearing off a portion of said wall or extracting one or more

several screws.

  It was then proposed, in particular in document EP-A-0 867 591, to provide the profile, at the level of the fixing zone, with an additional longitudinal chamber in which it is possible

  to introduce a massive profiled element of identical section.

  When the fixing screws are introduced, the latter pass through the wall of the profile and then engage by screwing into the solid element, passing through it if necessary, thus reinforcing the anchoring.

said screws in said profile.

  However, this solution is relatively expensive, since it requires the extrusion of an additional internal wall and therefore results in a more complex profile structure and a significant surplus of material, only a small portion of this internal wall being where appropriate.

  directly used to strengthen the fixation.

  -2- In addition, the massive profiled element having to have a section substantially identical to that of the receiving chamber delimited by the additional internal wall, the introduction of said element over a great length may prove difficult to achieve due to the surface friction between the faces of the latter and the internal faces of the wall of the chamber

reception.

  It is also known, as shown in Figure 1 of the accompanying drawings, to produce an extruded hollow profile in rigid thermoplastic material, intended in particular for the production of window frames and / or opening for doors, windows or the like, which comprises on at least one of its walls a zone for fixing by screwing elements or accessories for support, mounting, locking, bonding or the like, the wall concerned having at the level of said longitudinal zone of fixing an excess thickness of material on its internal face extending by two spaced parallel profiled wings, directed towards the interior of the chamber delimited by said wall and forming a passage with engagement for the threaded portions of the fixing screws When the screws are put in place, these the latter penetrate, by self-tapping, into the excess thickness of material, then between the two profiled wings extending the latter, the threads of the screw digging the walls of said wings by engaging them, thereby creating additional retention threads. Although significantly improving the solidity of the screw fixing, with a small surplus of material, compared to a simple profiled wall, this second known solution does not make it possible to obtain the performances, in terms of resistance and rigidity of fixing , provided by

  the first solution indicated above and as in particular by EP-A-

0 867 591.

  The object of the present invention is in particular to improve the aforementioned second solution in order to obtain performances equivalent to or even superior to those of the aforementioned first solution, this with a small excess of material and a profile structure whose complexity is not

significantly increased.

  To this end, the present invention provides a hollow extruded profile of rigid thermoplastic material, in particular of polyvinyl chloride, intended in particular for the production of window frames and / or opening for doors, windows or the like and comprising on at least 3 - one of its walls a zone for fixing by screwing elements or accessories for support, mounting, locking, bonding or the like, the wall concerned having at the level of said longitudinal fixing zone an excess of material on its internal face extending by two spaced apart wings or profiled lips, directed towards the interior of the chamber delimited by said wall and forming a passage with engagement for the threaded portions of the fixing screws, characterized in that said wings or lips are provided extensions, protuberances or recesses or delimit between them a groove or groove, forming one or more access sites profiling or anchoring for mounting by longitudinal threading of a fixing reinforcement profile comprising, on the one hand, a solid body for receiving by self-tapping the end at least of the threaded part of the fixing screws and , on the other hand, attachment means intended to engage on or in said attachment or anchoring sites for the solarization of said profile to said wings, the body of said profile being located in the mounted state in the

  extension of the passage delimited by said wings.

  The invention will be better understood, thanks to the description below.

  after, which relates to preferred embodiments, given by way of nonlimiting examples, and explained with reference to the appended schematic drawings, in which: FIG. 1 is a sectional view of a profile of a frame of window or door of the state comprising the second existing solution of the state of the art described above; Figures 2 and 3 are cross-sectional views of window or door frame profiles comprising a solution corresponding to a first embodiment of the invention; Figure 4 is a view on a different scale of the fixing area and the fixing reinforcement profile forming part of the profiles shown in Figures 2 and 3; Figures 5 and 6 are sectional views of frame profiles, similar to those of Figures 2 and 3, comprising a solution corresponding to a second embodiment of the invention, and, Figure 7 is a sectional view of profile of Figure 6 without

  fixing reinforcement profile.

  As shown in Figures 2, 3, 5 and 6 of the accompanying drawings, the extruded hollow section I in rigid thermoplastic material, in particular in - 4 polyvinyl chloride, intended in particular for the production of frames of frames and / or opening for doors, windows or the like, has on at least one of its walls a fastening zone 3 by screwing support, mounting, locking, bonding or similar elements or accessories, the wall 2 concerned having at the level of said longitudinal fixing zone 3 an excess thickness of material 4 on its internal face 2 'extending by two spaced profiled wings 5 and 5', directed towards the interior of the chamber 2 "delimited by said wall 2 and forming a

  5 "passage with engagement for the threaded portions of the fixing screws 6.

  According to the invention, the wings or lips 5 and 5 ′ are provided with extensions, protrusions or recesses 7, 7 ′ or delimit between them a groove or groove 7 ″, forming one or more attachment or profile anchoring for mounting by longitudinal threading of a fixing reinforcement profile 8 comprising, on the one hand, a solid body 9 for receiving by self-tapping the end at least of the threaded part of the fixing screws 6 and, on the other hand, attachment means 10, 10 '; 10 "intended to come into engagement on or in said attachment or anchoring sites 7, 7', 7" for the attachment of said section 8 to said wings 5 and 5 ′, the body 9 of said profile 8 being located in the assembled state in

  the extension of the passage 5 "delimited by said wings 5 and 5 '.

  The profile extensions, protuberances and / or recesses 7, 7 ′ may have various conformations and configurations in section, for example a shape complementary to the attachment means 10, 10 ′ of the profile 8, so as to make a connection by male / female or similar fitting, however allowing a

  easy sliding in the nested state.

  The body 9 of the profile 8 retained on the wings 5 and 5 'by cooperation of complementary shapes or engaged from the rear with tightening, acts as a locknut locked in rotation, providing an additional grip depth for the screws 6 and preventing their

extraction by unscrewing.

  According to a first embodiment of the invention, the two profiled wings 5 and 5 'end or are extended, each by a side extension portion forming opposite profiled hooking ears 7 and 7' and the means d 'attachment of the fixing reinforcement profile 8 consist of profiled lateral wings 10 and 10' parallel having free edges 11, 11 'folded towards each other and engaging - at the rear of the attachment ears 7 and 7 'during the mounting of said profile

  reinforcement fixing 8 on said wings 5 and 5 '(Figure 2 to 4).

  Advantageously, the attachment wings 10 and 10 ′ of the fixing reinforcement profile 8 engage with an elastic pinching on the wings 5 and 5 ′ extending the excess thickness of material 4 formed at the level of the fixing zone 3, the joining of said section 8 with the wings of said excess thickness of material 4 being effected by non-adjusted interlocking. Thanks to these arrangements, good resistance of the fixing reinforcement section 8 is obtained on the wings 5 and 5 ', the two opposite sets of wing 10 and edge 11 / wing 10' and edge 1 1 'forming two opposite jaws elastically enclosing the wings 5, 5 'and the ears 7, 7', and good retention of said profile 8 during the introduction of the screws 6 into the body

  solid 9 by pressing the edges 11, 1 'on the ears 7, 7'.

  The elasticity of the wings 5 and 5 ′ can be adjusted by making them longer or shorter and with a contact surface with the body 9 more or

smaller.

  The aforementioned arrangements also allow easy threading of the profile 8 on the wings 5 and 5 'because of the play existing between the wings 5, 5' and their ears 7, 7 ', on the one hand, and the wings 10, 10' , their folded edges 11, 1 1 'and the solid body 9, on the other hand, which allows sliding with a

limited friction.

  According to a second embodiment of the invention, shown in Figures 5 to 7 of the accompanying drawings, the attachment means 10 "consists of a profiled wing 14 ending in a rod or a bead 14 ', the groove or groove 7 "(also forming passage 5") having a section complementary to that of said means 10 "allowing engagement with maintenance by cooperation of shapes of said means in said groove or groove. In addition, to facilitate guiding during introduction and to ensure the blocking in lateral position of the solid body 9, the latter may comprise on either side of the base of the wing 14, grooves 15 and 15 'receiving , with shape cooperation the ends of the wings or lips 5 and '. This second embodiment will make it possible to achieve a gain in material greater than that obtained by the first mode. Note that the

  medium 10 "will be locally destroyed or split by screw 6.

  FIG. 6 shows a variant of this second embodiment, in which the gain in material has been optimized, by limiting the presence of material to the zone of passage of the screws 6 and to the proximal region. Profile 8 may or may not extend over the entire length of the

  profile 1, depending in particular on the extent of the fixing zone 3.

  The latter may be indicated on the visible face of the wall 2 concerned by the signaling of the receiving location or locations 12 of the screws 6, for example in the form of punctual recesses or of a

longitudinal groove or groove.

  The profile 1 may, of course, include one or more fixing zones 3, if necessary on several of its walls, in

  depending on the number and type of elements or accessories to be joined.

  According to a preferred application of the invention shown in FIG. 2 of the accompanying drawings, the fixing zone 3 is advantageously located at the level of the wall 2 forming the bottom of a receiving groove 13

of fitting (s).

  According to an additional characteristic of the invention, the fixing reinforcement profile 8 is made of a relatively hard thermoplastic material and of lower quality than the material constituting the hollow profile 1, for example polychloride of

recycled vinyl.

  Of course, the invention is not limited to the embodiments described and shown in the accompanying drawings. Modifications remain possible, in particular from the point of view of the constitution of the various elements or by substitution of technical equivalents, without leaving for

  as much of the scope of protection of the invention.
