Description

Locking hardware for particular blade slide.

The invention relates to a locking hardware for a particularly sliding blade that involves a mechanism of control provided with a slide provided with a pickup holder that presents a recess in which it is immobilized in translation, thanks to suitable tightening means, a latch body of hook or similar.

The present invention concerns the scope of the construction hardware and refers in particular to the lock fittings for sliding blades.

Obviously, numerous ironworks are already known lock for, sliding sheet corresponding to the description more above. Thus, such fittings are provided capable of positioning in the thickness of the front stile of the sliding leaf and they involve, very generally, a planned internal plate capable of come in the wall of the inner side against this leaf stud, while, at the level of its back face, it is provided with a box that houses, in a mobile way, a sliding. This involves, at level of your face in front of an opening provided on the plate internal, a bucket-shaped handle to drive your displacement from a locked position in the direction of a unlock position, and vice versa.

With this slide is associated a portapestillo, knowing that this involves a recess that extends substantially according to a direction perpendicular to the direction of sliding of the slide and into which the body of an intended hook latch capable of cooperating with a strike located in correspondence with the level of the amount of the Door frame, window or similar.

After all, the body of the latch hook comes immobilized in this recess of the toothbrush through of tightening means, in particular, a screw that passes through of a thread hole at the level of the toothbrush, to apply the blade that usually defines the body of the hook latch against the recess wall opposite to said screw.

They have already imagined solutions to increase the adhesion of the hook latch body in the recess of this portapestillo, so that its misalignment is avoided, or under the effect of a shock applied to said latch, or of a tensile force resulting, for example, from an attempt to effraction

Very often, these solutions consist of perform, on at least one of the faces of the hook latch, a denture or stretch mark designed to improve its adhesion to the wall trowel corresponding to the recess against which it is applied under the tightening effect imparted by the screw.

In certain cases, they are also performed in this hook latch body a succession of lights that they describe, at the same time, a kind of denture that, in cooperation with the tightening screw, it is supposed to increase the grip of the body of the hook latch with respect to the holder.

In particular, of the document GB-1396876 is known a locking hardware that It has a sliding mechanism referenced, which is provided with a toothbrush that it has a U-shaped groove recess in which it comes immobilized in translation, thanks to a screw tight, the body of a hook latch. This body is coming crossed by an elongated light that serves to pass the thyme Tight provided capable of cooperating with a screw hole provided at the bottom of the U-shaped slot corresponding to the recess in the holder.

On the other hand, one of the side walls of this recess involves a denture with which it is able to cooperate a conjugate shaped denture provided at the edge level lower body of the hook latch. After all, by this denture the latter can be adjusted in position transversely with respect to said spindle holder.

On the other hand, there are solutions in which the hook latch body is not maintained by tight at the level of the toothbrush, but by means of a thyme accessible adjustment, in particular, from the front edge of the blade slide. While such an adjustment thyme is capable of opposing, at less in part, to a relative displacement of the hook latch with respect to the portapestillo, that does not prevent that it leads to a design more complex and obviously of a higher cost.

The present invention aims to propose a simple solution for this grip problem, even of anchor, of a hook latch body at the level of a spider holder, whose solution is capable of opposing a relative displacement of these pieces relative to each other, in particular when they are applied on the hook latch abnormally high tensions, whether within the framework of a improper handling of the locking hardware, whether during a attempt, of effraction.

To this end, the invention relates to a hardware Locking for particularly loose slides that Comports a drive mechanism provided with a slide provided with a portapestillo that presents a recess in which it is immobilized in translation, thanks to adequate tightening means, a body of hook latch or similar, characterized in that at least the internal wall of the recess against which the body is applied of the hook latch, thanks to the tightening means, or the corresponding wall of this hook latch body, is provided with gripping means, preferably in the form of a dentures, provided capable of cooperating, by biting substantially in the material, with a ramp that extends in a direction that corresponds to the insertion direction of the latch body of hook at recess, this ramp being provided in, respectively, said corresponding wall of the body of the hook latch or internal wall of said recess.

According to a peculiarity of the present invention, said ramp is configured in the form of wedges in a direction that corresponds to the axis of the recess in the holder.

After all, within the framework of an action inventive has imagined reducing the surface on which it support the pointed ends of the teeth corresponding to said denture, to, conversely, increase, under the effect of pressure of the tightening means, the penetration of these teeth in the material corresponding to its support surface and so improve the grip of the pieces to each other.

If we imagine that the greatest risk that presents this type of locking hardware results from the possibility to remove the hook latch from its slide holder, during a attempted effraction, for example by a goat's foot or a similar tool, when configuring the wedge-shaped ramp to the which denture should be grasped, such an attempt will only have as consequence of increasing this grip effect and therefore to oppose, with a progressively increasing force, the removal of said hook latch with respect to its toothpick holder

The present invention will be better understood by reading the description that follows and with reference to the drawing attached that refers to an embodiment.

Figure 1 is a schematic representation in perspective and partial of a locking hardware according to the invention, the hook latch being removed, from its slide holder.

Figure 2 is a schematic and sectional view. partial of the holder corresponding to this ironwork of blocking.

Figure 3 is a schematic and partial view of the holder with the latch, according to a first mode of realization.

Figure 4 is a view similar to Figure 3, corresponding to a second embodiment.

As you can see in the figures in the drawing attached, the present invention relates to a locking hardware 1, in particular for a sliding door, window leaf or similar (not represented). For this purpose, such hardware lock 1 is usually integrated in the front upright of this sliding leaf and includes a blocking organ, in particular a hook latch 2, intended capable of cooperating, in the position of lock, with a strike arranged in the corresponding amount of the frame of this door or window.

So, this lock hardware 1 behaves. a internal plate 3 behind which a box 4 is provided capable of receiving at least part of the mechanism of drive 5 corresponding to this locking hardware 1.

For this purpose, this drive mechanism 5 is provided with a slide 6 provided capable of moving in said box 4 between a locked position and a position of Unlock To this end, this slide 6 has, on its side, facing the internal plate 3 and facing an opening 7 provided in the latter, a bucket-shaped handle 8 for actuation in displacement.

A slide holder is associated with this slide 6 9 provided with a recess 10 in which it is immobilized in translation, thanks to suitable tightening means 11, body 12 of the hook latch 2.

In particular and as can be seen in the Figure 2, the tightening means 11 consist of a screw of tight (not shown) inserted in a thread hole 13 of the pin holder 9. This thread hole 13 communicates with the recess 10, so that after insertion into the latter of the body 12 of the hook latch 2, the tightening of said screw has for consequence that this body 12 of the hook latch 2 come applied against the opposite wall 14 of this recess 10.

For this purpose and according to the invention, this wall internal 14 of recess 10, against which the body is applied 12 of the hook latch 2, including the corresponding wall 15 of the latter is provided with gripping means 16, preferably in the form of a denture 17, able to cooperate, by biting in the material, with a ramp 18 of which it is provided, the other way around, the corresponding wall 15 of the body 12 of the hook latch 2 or the wall 14, opposite the tightening means 11, of the recess 10.

It should be noted that these dentures 17 corresponding to the gripping means 16 can be presented in shape of stretch marks, as can be seen in figure 4, or result from the presence in the body 12 of the hook latch 2 of, a plurality of cuts parallel to each other by way of a ladder or rack A combination of these two solutions It can also be contemplated.

Ramp 18 which, in the embodiment corresponding to the attached drawing, is at the level of the wall 14 of recess 10 extends axially inside the latter, that is, in the sense of insertion of the body 12 of the hook latch 2.

On the other hand, in this direction this ramp 18 it is configured in the form of a wedge, as can be seen in the figure 3.

Thus, it can be progressively thick growing in a direction that corresponds to that of this sense of insertion of the body 12 of the hook latch 2 into the 9 holder or in the opposite direction. In the first case, yes well the extra grip that conferred denture 17 on the ramp 18 tends to increase even more under the effect of a crash that tends to push the hook latch 2 into the slide holder 9, a ramp 18 in the form of an inverted wedge will result, conversely, in an opposition to a traction intended to remove this hook latch 2 from the pin holder 9.

Although, as explained above, in the embodiment corresponding to the drawing figures attached ramp 10 is systematically associated with wall 14 of the recess 10 corresponding to the slide holder 9, one could perfectly imagine performing it at wall level 15 corresponding to the body 12 of the hook latch 2.

As it appears in particular in Figure 1, this body 12 of the hook latch 2 may also involve a series of openings 19 describing, in each other, highlights 20 in shape of dentures intended, here, too, to improve your grip with respect to the screw corresponding to the tightening means eleven.

Finally, as follows from the description above, a locking hardware according to the invention confers not only a greater degree of security, but also its Reliability over time is increased. In particular, in the absence of an anti-false maneuver device adapted, it is possible, following an error of handling, bring the locking hardware in its locked position while the sliding blade is open. Under such conditions, the hook latch necessarily bumps against the strike in the frame when the closing of this sheet occurs. While in the frame of the state of the art, such a shock often had as consequence the displacement of the hook latch, the present invention has been able to effectively alleviate this difficulty. Indeed, any attempt at relative displacement of the hook latch with respect to the portapestillo results, within the framework of a design according to the  invention, only in a greater interpenetration of the means of grab 16 on ramp 18.
