Description

The invention relates to an angle fitting having two wings perpendicular so as to take a position on the angle between a cross member and a door jamb, these wings comprising complementary attachment means defined able to cooperate with returns of hooking bordering the mouth of a T-shaped groove, at least the complementary fastening means of one of these flanges being capable of cooperating with these return snaps by engagement and clipping in the corresponding "T" groove, following a direction substantially perpendicular to the latter.

The present invention relates to the field of corner fittings for doors, windows or the like.

As a corner fitting, it is known, in particular by the document FR-2791388 , a rod exit guide in the form of a square piece coming to dress the angle of an opening frame at which is able to stand out one end of the operating rod. Also, one of the wings of this piece square bracket comes externally on the headrest. In addition, for good mechanical strength of the assembly, each of these wings is provided with an opening for the passage of a fastening screw cooperating with the joinery. Under these conditions, one of these fixing screws comes through, both, the headrest and the operating rod, the latter being necessarily provided with an oblong hole allowing the required mobility.

Similarly, we know from the document WO-98/41719 a square lock having two perpendicular wings able to come to fade in the T-shaped grooves that comprises, in the peripheral rabbet, a leaf of a PVC joinery or similar. One of these wings hosts, in a mobile way, a locking bolt. Each of said wings has, moreover on its lateral sides, grooves and ribs for cooperating by clipping with these T-slots at the level of the joinery. In particular, when mounting the lock on the leaf the ribs, configured in the form of redan, are able to fade the passage of the hooking edges that define the edges bordering the opening of such a groove T. In contrast, after fully interlocking in these T-slots, these ribs unfold elastically under these returns and oppose the disassembly of the lock.

First, it will be noted that the mounting of this lock on a joinery involves two operations of interlocking force: a first for the engagement of the first wing in the corresponding groove on the leaf and a second for ensuring the engagement of the second wing in its groove to it. In fact, it is not possible to pre-mount the lock on the leaf so that it is maintained when it seeks to clip the first wing in its groove. Finally this assembly proves relatively tedious.

Furthermore, such a lock can only be applied on joinery from a specific manufacturer. More specifically, it can be mounted only on a leaf having, in rebate, T-shaped grooves of a certain configuration and a precise depth.

However, many manufacturers have their own profiles for the design of their doors or windows. This results in different groove depths, not to mention that the actual configuration of these grooves can change. In particular, the implantation, with respect to the rabbet plane, the returns forming hooking flange, also changes very frequently, depending on these manufacturers.

In the end, the present invention has been able to meet the current constraints of standardization of fittings for carpentry.

It also makes it easier to perform the operations necessary to mount these fittings on a joinery. In this context, it makes it possible, especially, to consider this assembly without it being necessary to carry out long screwing operations.

In particular, in the case of an aluminum or reinforced PVC joinery, it is very often useful to pre-drill before installing a fixing screw or at least to use self-piercing screws. Furthermore, if laying errors are made, resuming the positioning of a fixing screw or its recovery in case of incorrect introduction may not be possible.

Nevertheless, this attachment by screw has been considered, until now, as responding to the particular constraints that are encountered in the field. In particular, it should be observed that a rod exit guide must be able to withstand the stresses that can be printed to it through said end of the operating rod which, in the locking position in which it is projecting in periphery of the opening, comes to cooperate with a strike arranged in correspondence on the frame. Under these conditions, if any traction is exerted on the opening, this rod end, locked in its striker, tends to reflect the stress on the guide and, of course, the fastening means which binds it to the carpentry.

Thus, the invention relates to an angle fitting having two wings perpendicular so as to take position on the angle between a cross member and a door jamb, these wings having complementary fastening means defined suitable to cooperate with snap returns bordering the mouth of a T-slot, at least the complementary fastening means of one of these wings being capable of cooperating with these return snaps by engagement and clipping in the groove in "T" corresponding in a direction substantially perpendicular to the latter.

In particular, these complementary attachment means, designed to cooperate by clipping with a "T" groove, are defined, at one or more tongues equipping each of the lateral sides of the wing, by at least two flanges. distinct attachment being located at different distances from the upper and outer face of said wing so as to be inserted by forming redan under a snap back of said T-slot.

Advantageously, one of the wings of this rod exit guide has a section adapted to that of a T-shaped groove adapted to be engaged from one end of the latter.

In this case, this wing comprises, on its lateral sides as complementary hooking means, grooves for receiving the returns defining the hooking edges that comprises a groove "T".

In the end, as is apparent from the particular features of the present invention, it has been able to take advantage of the provision of such a fitting in the angle of a leaf to facilitate assembly on the joinery. Advantageously, this corner fitting is adaptable to joineries from different manufacturers.

More particularly, in the figure 1 there is shown a window 3 having two leaves 2, 4 without central mullion, including a semi-fixed leaf 2 may be equipped with one or more immobilization locks 1B according to the invention. On this semi-fixed leaf 2 comes to close the leaf 4, called service.

In particular, in the absence of a central mullion and closing on the fixed frame 5 this service leaf 4, the amount before 6 comes to recovery of the corresponding front post 7 of the semi-fixed leaf 2.

The present invention is directed to joineries including a leaf 2, 4 comprises, rabbet 8, a groove 9 of T-shaped section adapted to receive fitting elements. In the end, the invention relates, more particularly, joinery designed by assembling profiles of aluminum or plastic PVC type.

Thus, the groove 9, shown schematically in the figure 2 , is delimited by a bottom 10, extending perpendicularly to the plane of the joinery, and side walls 11, 12 having, substantially at their free end, returns 13, 14 bordering the mouth 15 of this T-shaped groove 9.

In the Figures 3 and 4 , it is illustrated the implantation, in such a groove 9, a set of operating rod 16 - headrest 17, the latter housing, by closing the groove 9, said operating rod 16.

Under the control of locking a suitable control mechanism, the free end 18 of such an operating rod 16, arranged, for example, along a front post 6 of a service leaf 4, is susceptible extend beyond this amount before 6. By presenting, thus, projecting relative to the corresponding cross member 19 of the leaf 4, this free end 18 of the operating rod 16 is able to cooperate, such as an organ locking device, with a strike arranged in correspondence with the level of the fixed frame 5.

In the end, an angle fitting 1 in the form of a rod exit guide 1A serves to guide, in its movements between the locking and unlocking position, this end 18 of the operating rod 16, but also to maintain it and the headrest 17, integral with the corresponding end 20 of said front post 6.

In particular, this angle fitting 1 in the form of a rod exit guide 1A is part of the angle 21 between a cross member 19 and a post 6. It is composed of two wings 22, 23 provided adapted to come s engage in the T-slots 9 that includes the crosspiece 19 and the upright 6. At least one of 22 of these wings has a channel 24 for passage of the end 18 of the operating rod 2, this channel 24 being here provided suitable to also accommodate the end 25 of the headrest 17.

Thus, this channel 24 is opening at the level of the perpendicular wing 23 through an opening 26 at least adjusted for the passage of the end 18 of the operating rod 16.

Note that the wing 22 is provided capable of capping the rod assembly 16 and headrest 17 and comprises, therefore, a cover tab 27 extending to the front of the headrest 17.

Each of the flanges 22, 23, defining this angle fitting in the form of a rod exit guide 1A, comprises complementary fastening means, respectively, 28 and 29 defined capable of cooperating with the attachment means constituted by the returns 13, 14 bordering the mouth 15 with a T-shaped groove 9.

Preferably, one of the wings 22 has a section adapted to that of such a T-shaped groove 9 so as to be engaged from one end in the latter. In fact, on its lateral sides 30, 31, this flange 22 comprises, in the form of recesses, hooking flanges 32, 33, which can extend, on the inside, to a groove 9, under said returns 13, 14, so as to prevent this wing 22 to get out of this groove 9 by a displacement perpendicular to the axis of the latter.

In addition, the complementary attachment means 29, corresponding to one of these wings 23 are defined capable of cooperating with such returns 13, 14 of a groove 9 by engagement and clipping in the latter in a direction substantially perpendicular to the axis of it.

More particularly, such complementary attachment means 29 are defined on the lateral sides 34, 35, of a wing 23, by a catch flange 36 which, when inserted into a T-shaped groove 9, is designed to be elastically erasable to the passage of a return 13, 14 and, at the end of insertion in this T-slot 9, extend under this return 13, 14 forming redan.

According to a preferred embodiment, a catch flange 36 is associated with a tongue 37 formed at such a lateral side 34, 35 of this flange 23.

Such tongue 37 is tapered at its free end 38 so as to facilitate the insertion of the corresponding flange 23 into said T-shaped groove 9.

Insofar as the depth of such a T-shaped groove 9 is likely to vary and / or the distance of the returns 13, 14 with respect to the rabbet plane 39 may change according to the carpentry manufacturers, the complementary fastening means 29 are defined, on each of the lateral sides 34, 35, of such a flange 23, by at least two attachment flanges 36, 36 ₁ , 36 ₂ at different distances from the outer upper face 40 of this wing 23.

The hooking flanges 36, 36 ₁ , 36 ₂ may be associated with one and the same tongue or tabs 37, 37 ₁ , 37 ₂ separate, as shown in the figures of the accompanying drawings. Thus, depending on the depth of engagement in a groove 9, the hooking flange corresponding to one or other of these tongues is inserted by forming redan under a return 13, 14 of this groove 9, so as to prevent the rod exit guide 1A from escaping therefrom.

The angle fitting 1, according to the invention, can still be in the form of a locking immobilizer 1B that is shown in FIG. figure 7 .

Especially, in the context of a configuration as illustrated in the figure 1 , that is to say a window 3 with two leaves 2, 4, without central mullion, when the unlocking command and opening of the service leaf 4, such immobilization lock 1 comes to prevent the leaf semi-fixed 2 does not open, in turn, automatically.
