Description

The invention relates to a mounting element, of the striker type, designed to be fixed in a "T" groove formed in a rabbet of an opening frame or of a door frame, window or the like, said groove being bordered, at its mouth, by longitudinal returns, while the fitting element comprises a base under which extends a shoe defining fixing means in said "T" groove, this shoe being of width adjusted to the passage preserved between said longitudinal returns.

The present invention relates to the field of building hardware, particularly that of hardware or fittings for fitting a door, window or the like made of synthetic material, in particular PVC, or aluminum.

In this regard, such doors or windows comprise a frame and at least one opening frame designed by an assembly of profiles defining a rabbet groove section usually "T" provided to receive fittings elements, including locking and / or articulation.

In the end, it is a question of positioning and fixing this type of fitting element on and / or in such a groove by means of appropriate positioning and fixing means.

These fixing means can take different forms of embodiment. In particular, it is known to insert, by sliding in the wide part of the groove, a metal blade having tapped orifices with which are provided to cooperate fastening screws passing through the fitting element. Finally, such fixing blades play the role of nut.

It has further been imagined to equip the base of a shoe element of a shoe able to be inserted into said groove "T", this shoe comprising complementary means which, for example under the action a screw, come to ensure the fixing and clamping of this fitting element. In particular, these additional means may be in the form of one or more gripping fingers which, during the assembly and dismounting phase of the fitting element, are able to retract into said shoe and vice versa under action of a screw, come hang under the rims bordering at its mouth said groove "T".

More simply, such a shoe has an opening for the passage of a fixing screw intended to be housed in groove bottom in the joinery.

It will be noted that in the known embodiments described above the mounting and prepositioning of such a fitting element on a profile of the type indicated above for preliminary operation tests is a tedious and time consuming operation. Indeed, to perform these tests, it is necessary to act on one or more screws to ensure the immobility in translation of the fitting element in its groove without counting, if necessary, the holes that should be perform at said profile for the reception of this or these screws. Then, it turns out, at the end of these tests that it is necessary to resume the position of these fittings, it is necessary, first of all, to unscrew all these screws, move the fittings, screw, even drill again before doing new tests and so on.

FR-A-2,747,433 also discloses a fitting element, in particular a striker, comprising a base provided with fastening means in such a "T" groove, these fixing means being completed by hooking means intended to cooperate with a hooking flange located at the rabbet of the profile defining an amount or a cross member of a door, window or the like of PVC, aluminum or the like.

More specifically, the attachment means are in the form of a return parallel to the base and being located at the free end of an extension extending perpendicularly and rear edge of this base. In the mounted position of the fitting element, this return is positioned under the hooking flange extending in a plane parallel to the groove "T", in a direction opposite to the latter.

In fact, this hooking flange is defined through a notch made in a stiffening chamber adjacent said groove "T". The length of this notch is adjusted so that it prevents any translational movement of the fitting element relative to the profile, therefore in the groove. As for the fixing means, they are designed to allow clipping mounting of the fitting element on the profile. Thus, these fixing means are in the form of a shoe integral with the lower face of the base and whose width is adjusted to the passage preserved at the groove in "T" between the two returns bordering it to height of its mouth. This shoe comprises, in addition, on one of its lateral sides facing one of these returns, a redan rim coming to anchor under said return. In addition, on its opposite lateral side, the shoe is chamfered to allow its nesting in the groove "T".

It will be noted, in particular, that immobilization in translation of this fitting member in the groove is ensured only once the return, which is equipped with its base, brought in cooperation with this snap flange at the stiffener chamber. Also, it can not be considered that the fitting member is provided with prepositioning means with respect to the groove, since in case of subsequent repositioning, it is necessary to proceed to a further notching of the stiffening chamber. This notching is then no longer adjusted to the hooking return of the fitting element which can be immobilized in translation only by means of a fixing screw.

Similarly, from DE-U-94 12 070, there is known a striker-type fitting element comprising a base under which extends a shoe defining fastening means in a groove "T" groove a carpentry. This shoe comprises, on one of its longitudinal sides facing a return bordering said groove, a fastening flange provided adapted to extend under said return once the fitting element in position.

On the same longitudinal side, the base also extends and also has a hooking flange extending substantially parallel to the shoe so as to be able to extend to the rear of a shoe. shoulder defined at the level of carpentry.

Finally, on the opposite side, said shoe is provided with anchoring lugs (6), defined in the form of a step and which, when the fitting element is fully engaged in the "T" groove, come, again, extend under the return of this groove in "T", opposed to the return under which is hooked the hooking flange equipping the opposite longitudinal side of the shoe.

Note, moreover, that the edge of these anchor lugs in the form of redan, precisely coming into position under the return of the groove "T", is sharp.

Accordingly, this German utility model describes means for attaching a fitting element in a "T" groove of a joinery, more particularly in PVC, which does not require the use of parts fasteners, such as screws. Under these conditions, these fixing means do not allow any prepositioning of this fitting element at the level of the joinery for prior testing.

In the end, the present invention is able to meet these disadvantages by proposing a fitting element that can be easily prepositioned, for preliminary tests, along the groove intended to accommodate it without any problem. it is necessary to use an additional fastener, such as a screw or the like. In addition, such a fitting element, according to the invention, is able to be repositioned, later, along said groove in a simple manner.

To this end, the invention relates to a striker-type fitting element, intended to take a position, to be fixed in a "T" groove formed in a rabbet of an opening frame or a door frame, window or the like, said groove being bordered, at its mouth, by longitudinal returns, while the fitting element comprises a base under which extends a shoe defining fastening means in said "T" groove, this shoe being of width adjusted to the passage preserved between said longitudinal returns, the shoe having on at least one of its longitudinal sides, facing a return, a fastening flange provided adapted to extend, at least partially, under this return while the opposite longitudinal side of said shoe is provided with at least one tightening bead capable of defining a tight fit of said shoe between the longitudinal returns of the groove "T".

According to a preferred characteristic, said clamping bead extends on the longitudinal side of the shoe in a direction perpendicular to the plane of the "T" groove and is chamfered in its lower part to facilitate its insertion into this groove.

The advantages of the present invention are that the clamping bead does not have the sole function of ensuring a tight fitting of the shoe of the fitting element in the groove of the profile, but, because of its weak zone of contact with the corresponding return of the groove, it creates, in addition, some anchoring of the fitting element in the latter. This effect is further amplified by means of anchoring means located on the opposite side of the shoe.

According to another preferred feature of the present invention, the longitudinal side of the shoe opposite the clamping flange comprises anchoring means in the thickness of the wall defining a longitudinal return of the groove "T".

The invention will be better understood from the following detailed description of an exemplary embodiment.

The understanding of this description will be facilitated by referring to the attached drawing in which:

• FIG. 1 is a schematic representation in section and in part of a frame of a fixed frame receiving a fitting element in the form of a keeper adapted to cooperate with a locking member of a locking fitting housed at level of a profile corresponding to a door opening frame, window or the like;

• Figure 4 is a bottom view of Figure 3;
• Figure 5 is a left view of Figure 3;
• FIG. 6 is a view from above of FIG.

As shown in Figures 1 to 6 of the accompanying drawings, the present invention relates to a fitting element 1, here more particularly represented in the form of a striker, intended to take a position, to be fixed, in a groove "T" 2 as found in rabbet 3, 4, a frame 5 and / or an opening frame 6 of a joinery door, window or the like, designed based on profiles made of synthetic material, in particular PVC, or of metal type such as aluminum.

More particularly, the "T" groove 2, whose longitudinal median plane 7 is substantially parallel to the plane of the fixed frame 5 or, as the case may be, of the opening frame 6, comprises a bottom 8 from which lateral walls extend. 9, 10 having at their ends a longitudinal return 11, 12. These border, therefore, longitudinally, the mouth 13 of this groove "T" 2.

As for the fitting element 1, it comprises a base 14 under which a shoe 15 generally defines means for fastening this fitting element 1 in said "T" groove 2. shoe 15 has a width 16 adjusted to the passage 17 preserved at the groove "T" 2 between the two returns 11, 12.

Finally, on at least one 19 of its longitudinal sides 18, 19, opposite a return 12, the shoe 15 has a fastening flange 21, continuous or discontinuous, provided able to extend, at least partially, under this return 12, knowing, in addition, that the opposite longitudinal side 18 of said shoe 15 is further provided with at least one clamping flange 22. This is intended to define a tight fit of said shoe 15 between the longitudinal returns 11, 12 of said "T" groove 2.

Note that this clamp 22, is preferably in the form of a boss extending on the longitudinal side 18 of the shoe 15, perpendicularly from the base 14, so in a direction perpendicular to the plane of the groove. "T" 2. This boss is, moreover, chamfered in its lower part 22A so as to create an engagement ramp in the groove "T" 2, the back of the return 11.

Preferably, this clamping bead 22 is of semi-cylindrical shape 26 so as to have a contact zone with the return 11 of the groove "T" 2 relatively small. Under these conditions and under the effect of the clamping occurring at the time of engagement of the fitting element 1 in the "T" groove 2, this clamping bead 22 marks, locally, said return 11 and provides, this fact, a certain anchoring of this fitting element 1 along said groove "T" 2.

It should be noted that, as can be seen in the various figures of the accompanying drawings, the side 18 of the shoe 15 comprising the clamping bead 22 can still receive, as the opposite side 19, a continuous or discontinuous engagement flange 20 intended to extend, at least partially, under the corresponding return 11 of the groove "T" 2.

According to a preferred embodiment (see FIG. 4), the clamping bead 22 takes position, at the level of the shoe 15, substantially at the height of the median plane of the fitting element 1, whereas the hooking flange 20 is discontinuous. extends on either side of said clamping bead 22.

Again, the shoe 15 is chamfered, preferably from this hooking flange 20 towards its lower face 24 so as to create a ramp 25 intended to facilitate this hooking rim 20 crossing the return 11 of the groove in "T" 2.

Similarly, in order to facilitate the tilting of the fitting element 1 around the return 12, once the hooking flange 21 engaged on the latter, said return 12 can be chamfered externally to the groove 2, as visible in the Figures 1 and 2.

It will be observed again that, compared to this hooking flange 20, intended to be clipped under the longitudinal return 11, the one 21 located on the side 19 of the shoe 15, therefore on the side opposite the clamping flange 22, can be defined greater width since it is slid under the corresponding return 12 of the groove "T" 2 in the initial phase of mounting in the latter, the fitting element 1.

According to another feature, this longitudinal side 19 of the shoe 15 opposite the clamping bead 22 comprises means anchoring device 27, in the form of protruding studs 28, extending substantially from said hooking flange 21 in the direction of the base 14 of the fitting element 1. Such anchoring means 27, in the form of pins 28, are provided to force fingerprints in the thickness of the wall defining said return 12 so as to contribute to the anchoring action of the fitting element 1 along the groove in " T "2 in the absence of other fasteners, such as screws or the like.

Preferably, these pins 28 comprise a wider base in the direction of the hooking flange 21 and are, therefore, tapered towards the base 14, giving them a substantially pyramidal shape.

Such a configuration is intended to facilitate both the installation of the fitting element 1, but also the notching, through the edge of these pins 28, the thickness of the material corresponding to the return 12 In addition, the pyramidal shape of these pins 28 opposes any possibility of play by providing an anchoring which increases under the action of forces exerted on this fitting element 1, illustrated through the arrow 30 on the Figure 1, which is now in question.

As can be seen in this FIG. 1, such a fitting element 1, in particular when it is a keeper intended to accommodate a locking member 29, corresponds to a locking fitting taking a rabbet position 4 of the opening frame 6. may be made to undergo certain efforts. In particular, whether under the action of the locking itself or during an attempted break-in, such a fitting element 1, in the form of a striker, undergoes forces perpendicular to the plane of the door, window or analogous, from the outside towards the interior of the dwelling, as represented by this arrow 30. Under these conditions, the largest hooking flange 21 is located, preferably, on the longitudinal side 19 of the shoe 15 opposite to such forces, therefore to the boom 30. As for the base 14, it advantageously defines, at least on the opposite side 18 of this shoe 15, a support plane 31 intended to bear largely at the edge 32 of the groove "T" 2.

In fact, on the longitudinal side 19 of this shoe 15, the base 14 is preferably devoid of such a support plane so as to allow, after a first fitting of the fitting element 1 in the groove in " T "2, its disassembly by a reverse movement to the mounting operation, so by tilting around the return 12 advantageously chamfered for this purpose.

Thus, as is apparent from the foregoing description, the fitting element 1, according to the invention, can be easily prepositioned in the "T" groove 2, prepositioning which guarantees its anchoring in the latter in order to preliminary functional tests, beyond which it may be necessary to reposition this fitting element 1.

Finally, it is only once these tests have been conclusively carried out that the fitting element 1 can be definitively fixed in the "T" groove by means of a fixing screw or the like. The shoe 15 may, moreover, be traversed by one or more openings, as shown in Figure 4, for the passage of such fastening screws.
