Description

Locksmith type hardware element.

The invention relates to an element of ironwork, locksmith type, intended for positioning, for fixing in it, in a "T" shaped slot provided in the renewal of a leaf or a door, window or frame similar, said slot being delimited, at the level of its mouth, by longitudinal elbows, while the hardware element it includes a base under which a shoe extends that defines fixing means in said "T" shaped groove, being this shoe of width adjusted to the step preserved between said longitudinal elbows.

The present invention relates to the scope of the construction hardware, particularly that of the hardware or hardware parts intended to equip a door, window or similar of synthetic material, in particular PVC or aluminum.

For this purpose, such doors or windows they involve a frame and at least one sheet made of a assembly of profiles that define a slot in the renvalso section usually in the form of "T" intended to receive hardware elements, in particular locking and / or joint.

After all, it's about positioning and fixing this type of hardware element on and / or in such a groove thanks to appropriate positioning and fixing means.

These fixing means can adopt Different embodiments. In particular, it is known insert, by sliding in the wide part of the groove, a sheet metal with internal thread holes with the which must fix fixing screws that pass through the hardware element. Finally, such fixing sheets They play the role of a nut.

He has also imagined equipping the base of a hardware element with a shoe capable of being inserted in said "T" shaped slot, this shoe behaving means complementary that, for example under the action of a screw, ensure the fixing and tightening of this hardware element. In In particular, these complementary means can be presented in shape of one or more hooking fingers that, during assembly and disassembly of the hardware element, they are able to retract in said shoe, and conversely, under the action of a screw, is they hook under the elbows that delimit, at the level of their mouth, said "T" shaped groove.

More simply, such a shoe involves a opening for the passage of a fixing screw intended for Stay at the bottom of the groove in the carpentry.

It will be noted that, in the embodiments known described above, assembly and prepositioning of such hardware on a profile of type indicated above with a view to performance tests Previous are an annoying and long operation. Indeed, to be able perform these tests, it is convenient to act on one, even several screws, to ensure the immobility in translation of the element of hardware in its groove, in addition to, where appropriate, perforations which should be done at the level of said profile for the reception of This or these screws. Then, performed these tests, it turns out that it is necessary to correct the position of these hardware elements, First of all you have to loosen all the screws, move the hardware elements, re-tighten, even re-drill, before performing new tests, etc.

Of the document FR-A-2,747,433 is also known a hardware element, in particular a strike that involves a base provided with fixing means in such a groove in the form of "T", these fixing means being completed with means of hooked intended to cooperate with a hooked flange that places in the renvalso of the profile that defines an amount or a crossbar of a door, window or similar of PVC, aluminum or Similary.

More precisely, the hooking means are they present in the form of an elbow parallel to the base and are located at free end of an extension that extends perpendicularly and on the back edge of this base. In a mounted position of the hardware element, this elbow comes positioned below the hook flange that extends into a plane parallel to the "T" shaped groove, in one direction opposite to the latter.

In fact, this hooked flange comes defined by a notch made in a reinforcement chamber that adjoins this "T" shaped slot. The length of this notch is adjusted so as to prevent any movement of translation of the hardware element with respect to the profile, therefore in the groove As for the fixing means, these are designed so as to authorize the assembly by force of the element of profile hardware. Thus, these fixing means are presented in the form of a solidarity shoe on the underside of the base and whose width is adjusted to the passage preserved at the groove level in the form of "T" between both elbows that limit the latter to the height of its mouth. This shoe also includes one of  its lateral sides, facing one of its elbows, a flange that it forms a rediente and that is anchored under said elbow. Also in its opposite side, the shoe is chamfered to authorize its "T" shaped slot groove.

It will be noted, in particular, that the immobilization in translation of this hardware element in the groove is only secured when the elbow, from which its base is provided, is carried in cooperation with this flange of engagement at the level of the reinforcement chamber. Therefore, it cannot be considered that the hardware element is provided with prepositioning means with respect to the groove, since, in case of subsequent repositioning, a complementary notch of the reinforcement chamber must be performed. This notch will no longer be adjusted to the coupling elbow of the hardware element that can only be immobilized in translation by means of a screw
fixation.

Also, of the document DE-U-94 12 070 an element is known of ironwork of type locksmith that includes a base under the which extends a shoe that defines fixing means in a "T" shaped groove in the renovation of a carpentry. This shoe behaves, on one of its longitudinal sides, facing the elbow which delimits said groove, an intended engagement flange capable extending under said elbow when the hardware element be in position

On this same longitudinal side, the base, by on the other hand, it extends and also involves a flange of hooked that extends substantially parallel to the shoe, so that it is able to extend behind one shoulder defined at the level of carpentry.

Finally, on the opposite side, said shoe is provided with anchoring nails (6) defined in the form of a groove and that, when the hardware element is fully inserted in the "T" shaped groove, also extend under the elbow of this "T" shaped groove, opposite the elbow below the which hooks the engagement flange of which the opposite longitudinal side of the shoe.

It will be noted, on the other hand, that the flange of these anchoring nails in the form of a reddent that are positioned, precisely, under the elbow of the "T" shaped groove, it is cutting.

Therefore, in this utility model German means are described that allow to fix an element of hardware in a "T" shaped groove of a carpentry, in particular PVC, which do not require the use of fixing organs, such as screws. Under these conditions, these means of fixing do not authorize any prepositioning of this element of carpentry level hardware for testing previous.

Finally, the present invention is intended to be able to solve these different problems by proposing a hardware element that can easily be pre-positioned, with pre-test views, along the slot intended for welcome it, without the need to resort to a fixing body additional, such as a screw or the like. In addition, such an element of hardware according to the invention claims to be able to be repositioned, subsequently, simply along said groove.

To this end, the invention relates to an element of ironwork of type locksmith, planned to position itself, for its fixing in it, in a slot in the form of "T" provided in the renvalso of a leaf or a door, window or frame similar, said slot being delimited, at the level of its mouth, by longitudinal elbows, while the hardware element it includes a base under which a shoe extends that defines fixing means in said "T" shaped groove, being this shoe of width adjusted to the step preserved between said longitudinal elbows, this shoe behaving on at least one of its longitudinal sides, facing an elbow, a flange of envisaged capable of extending, at least partially, below this elbow, while the opposite longitudinal side of said shoe is provided with at least one tightening weatherstrip capable to define a tight fit of said shoe between the elbows longitudinal of the groove in the form of "T".

According to a preferred feature, said Tight weatherstrip extends, on the longitudinal side of the shoe, according to a direction perpendicular to the plane of the groove in "T" shape and is chamfered at the bottom, to facilitate its insertion in this slot.

The advantages of the present invention consist of in which the tight seal does not have the sole function of ensure a tight mounting of the hardware element shoe in the profile groove, but because of its small area of contact with the corresponding slot elbow also creates a certain anchoring of the hardware element in the latter. This effect is even more amplified through anchoring means that placed on the opposite side of the shoe.

According to another preferred feature of the present invention, the longitudinal side of the shoe opposite the Tight weatherstripping means anchoring means in the thickness of the wall defining a longitudinal elbow of the groove in the form of "T"

The invention will be better understood upon reading. of the detailed description that follows and which refers to an example of realization.

The understanding of this description will be provided with reference to the attached drawing, in which:

Figure 1 is a schematic representation in section and partial of a frame profile that receives an element of ironwork in the form of a locksmith intended to cooperate with a blocking organ of a blocking fitting housed at the level of a profile corresponding to a door leaf, window or the like;

Figure 2 is a schematic representation and in detail of figure 1 illustrating the hardware element, in Locksmith form, during its fixation in the groove in the form of "T";

Figure 3 is a schematic representation and in elevation of the hardware element alone;

Figure 4 is a bottom view of the figure 3;

Figure 5 is a view from the left of figure 3;

Figure 6 is a top view of the figure 3.

As it is represented in figures 1 to 6 of the attached drawings, the present invention relates to a hardware element 1, represented here in particular in the form of strike, intended for positioning, for fixing therein, in a "T" shaped slot 2, just as they are found in the renvalso 3, 4 of a frame 5 and / or a sheet 6 of a carpentry of type door, window or similar, made based of profiles of synthetic material, in particular of PVC, or also metallic type, such as aluminum.

In particular, the "T" shaped slot 2, whose longitudinal median plane 7 is substantially parallel to plane of the frame 5 or, as the case may be, of the sheet 6, implies a bottom 8 from which side walls 9, 10 are presented, at its ends, a longitudinal elbow 11, 12. The latter therefore, longitudinally delimit the mouth 13 of this "T" shaped slot 2.

As for the hardware element 1, this one it has a base 14 under which a shoe 15 extends which generally defines fixing means of this element of hardware 1 in said "T" shaped slot 2. Thus, this shoe 15 has a width 16 adjusted to step 17 preserved at the level of the "T" shaped groove 2, between both elbows 11, 12.

Finally, on at least one of its sides Longitudinal 18, 19, facing an elbow 12, the shoe 15 behaves a continuous or discontinuous engagement flange 21, provided capable to extend, at least partially, below elbow 12, knowing, furthermore, that the opposite longitudinal side 18 of said shoe 15 is also provided with at least one tight weatherstrip 22. The latter serves to define a tight fit of said shoe 15 between the longitudinal elbows 11, 12 of said "T" shaped groove 2.

It will be noted that this tight seal 22 is preferably, in the form of a bushing that extends in the longitudinal side 18 of the shoe 15, perpendicularly from the base 14, therefore in a direction perpendicular to the plane of the "T" shaped slot 2. This bushing is also chamfering at its bottom 22A, so that it creates a ramp of insertion in the "T" shaped slot 2, behind the elbow eleven.

Preferably, this tight seal 22 is semi-cylindrical 26, so that it has an area of contact with elbow 11 of the "T" shaped groove 2 relatively small Under these conditions and under the action of tight that intervenes at the time of insertion of the element of hardware 1 in the "T" shaped slot 2, this weatherstripping tight 22 marks, locally, said elbow 11 and causes, therefore therefore, a certain anchor of this hardware element 1 to the length of said "T" shaped slot 2.

It should be noted that, as can be seen in the different figures of the attached drawings, side 18 of the shoe 15 that carries the tight weatherstrip 22 can also receive, like the opposite side 19, a hooked flange 20 continuous or discontinuous intended to extend, at least partially under the corresponding elbow 11 of the groove in "T" shape 2.

According to a preferred embodiment (see Figure 4), the tightening weatherstrip 22 is positioned, at the level of the shoe 15, substantially at the height of the median plane of the hardware element 1, while hook flange 20, discontinuous, it extends on both sides of said tightening weatherstrip 22

Here too, shoe 15 is chamfered, preferably from this engagement flange 20, in the direction of its lower face 24, so that it creates a ramp 25 intended for facilitate this hooking flange 20 to pass over the elbow 11 of the "T" shaped groove 2.

Also, with a view to facilitating the overturning of hardware element 1 around elbow 12, once the flange of hooked 21 hooked on the latter, said elbow 12 may be chamfered externally to slot 2, as can be seen in Figures 1 and 2.

It will also be noted that, compared to this hook flange 20, in a way intended to be inserted by force under longitudinal elbow 11, that 21 located on side 19 of shoe 15, therefore on the opposite side to the tightening weatherstrip 22, it can be defined in width more important, since it is slipped under the corresponding elbow 12 of the "T" shaped slot 2, in the initial phase of assembly thereof, of the hardware element 1.

According to another feature, this side longitudinal 19 of the shoe 15 opposite the tightening weatherstrip 22 it includes anchoring means 27, in the form of edge lugs 28 projection, which extend substantially from said flange of hooked 21 in the direction of the base 14 of the hardware 1. Such anchoring means 27, in the form of studs 28, are provided able to force traces in the thickness of the wall that defines said elbow 12, so that they contribute to the anchoring action of the hardware element 1 along the "T" shaped groove 2 in the absence of other fasteners, such as screws or Similar.

Preferably, these studs 28 involve a wider base in the direction of the engagement flange 21 and are, by consequently, sharper in the direction of base 14, which confers a substantially pyramidal shape.

Such configuration is intended to facilitate the time, the placement of the hardware element 1, but also the notched, by the edge of these studs 28, of the thickness of the material corresponding to elbow 12. In addition, the pyramidal form of these tetons 28 opposes any game chance providing an anchor that is growing under the action of efforts exerted on this hardware element 1, illustrated by arrow 30 in figure 1 and which is now.

As you can see in this figure 1, such hardware element 1, particularly when it comes to a planned strike capable of receiving a locking device 29 that corresponds to a locking hardware that is positioned in the renvalso 4 of sheet 6, can be subjected to certain efforts. In particular, either under the action of the blockade itself or during a attempted robbery, such hardware element 1, in the form of strike, is subjected to perpendicular efforts to the plane of the door, window or similar, from the outside to the inside of the housing, as represented by this arrow 30. In such conditions, the largest engagement flange 21 is situated, preferably, on the longitudinal side 19 of the opposite shoe 15 to such efforts, therefore to arrow 30. As for the base 14, this advantageously defines at least the opposite side 18 of this shoe 15, a support plane 31 intended to support widely at the edge 32 of the "T" shaped groove 2.

In fact, of the longitudinal side 19 of this shoe 15, base 14 is preferably devoid of such a plane of support, so that it allows, after a first assembly of the element fitting 1 in the "T" shaped slot 2, its disassembly by a reverse movement to the assembly operation, so both by tipping around elbow 12 advantageously chamfered to such end

Thus, as is clear from the description preceding, the hardware element 1, according to the invention, can be easily prepositioned in the "T" shaped slot 2, which prepositioning guarantees its anchorage in the latter with views of previous performance tests, after which you can it is necessary to reposition this hardware element 1.

Finally, only when these tests are done conclusively, the hardware element 1 can be definitely fixed in the "T" shaped groove by a fixing screw or similar. The shoe 15 can also be crossed by one or several openings, as can be seen in Figure 4, for the passage of such fixing screws.
