Description

The invention relates to a fitting, in particular an operating fitting, for surface mounting on a hollow profile of an opening, provided with a quick fastening device comprising a clamping flange.

In the present text, the term "fitting" in its widest sense is used to designate any device intended to be fixed on a frame or on a door frame (door, window, etc.) that this door is sliding. , swinging or flying. By way of non-limiting example, this term covers operating handles, espagnolette handles, espagnolettes, recessed handles in the form of shells intended to be fixed to metal or synthetic hollow profiles (for example PVC) used in carpentry . The fittings, within the meaning of this document, can be associated with complementary mechanisms, fixed by themselves or not on the profiles, such as cremones, locks, etc.

To fix these fittings, it is common to first fix a mechanism, for example a lock, on a profile forming a frame of an opening, for example by inserting it on the edge of the opening, opposite the Edge of the frame, then fix the fitting maneuver applied to one of the faces (inner or outer) of the frame by screwing directly on the housing of the mechanism.

However, and particularly when these fittings are made to withstand significant maneuvering torques as is the case for pull handles of sliding sashes (or handles of espagnolette on which is also applied a pulling force), the operating torque is applied to the housing of the mechanism before being taken up by the profile on which it is fixed. This results in deformations both of the case of the mechanism itself and of its attachment to the profile, which can lead to problems of adjustment of the mechanism (for example a bolt-latch offset for a lock) affecting the function of that -this.

To avoid this drawback, various solutions have been employed, aimed at fixing the fitting directly on the profile, independently of the mechanism with which it is associated.

For example, we know FR 2,877,979 a locking device comprising an operating handle mounted on a support fixed on the front wall of the profile of an opening by means of inner jaws inserted into a wall slot and coming to tighten the wall of the profile against the surface of the support .

However, in order to be able to deploy the inner jaws from their mounting position to their attachment position in order to clamp a significant part of the wall of the profile, it is necessary to provide a large deployment stroke and therefore a long screwing time. The implementation of this solution is therefore expensive.

We also know FR 2 808 832 a locking fitting of a sliding leaf comprising a bowl handle recessed from the outside in a slot of the front wall of a profile and fixed on this section by means of a so-called quarter-turn flange.

The flange consists of a substantially cylindrical piece, rotatable about an axis perpendicular to the wall, having on a first angular sector a flat portion parallel to its axis of rotation and over the rest of the circumference, a helical ramp adapted to tighten the wall of the profile against a finishing plate of the handle plated on the outer face of the profile.

The flange is rotatable in a cage fixed to the body of the handle between a first position, in which the flat is opposite the edge of the light, thus allowing the handle to be inserted into the profile and a second position in which the helical ramp is deployed beyond this edge, inside the profile to tighten the wall.

While this flange fixing device generally gives satisfaction on the assembly time, it is nevertheless expensive because of the complexity of the parts (flange, cage) and has the disadvantage, during tightening, of developing a pair parallel to the plane of assembly. the wall due to the friction of the ramp of the flange against it. This torque has the effect of tending to move the handle at the time of tightening and to prevent proper positioning thereof if the clearance between the recessed housing and the edges of the light is too important. In addition, repeated maneuvers such as opening and closing of the opening can cause loosening of the flange due to the torque generated by the force applied during these maneuvers.

We also know FR 2518628 a locking fitting corresponding to the preamble of claim 1.

The present invention aims to overcome these disadvantages and aims to provide a fitting having a fixing device on a wall of a hollow profile that allows a quick implementation.

The invention further provides a fitting that can be placed and fixed in a short time and without the clamping changes its position.

The invention also relates to a fitting whose fastener does not loosen during repeated maneuvers.

The invention further provides a fitting that does not require a precise adjustment of the light formed in the wall of the profile.

The invention also relates to a fitting whose fixing device allows a simple installation on site without requiring complex adjustment.

The invention also relates to a fitting comprising a fixing device using simple elementary parts.

• un corps présentant une face plane, dite face d'appui, destinée à être montée en applique sur une paroi, dite toile, d'un profilé creux d'un ouvrant,
• un dispositif de fixation de la ferrure sur la toile, adapté pour s'engager dans une lumière ménagée dans la toile et comportant au moins :
  • o un alésage d'axe orthogonal à la face d'appui, traversant le corps,
  • o une bride adaptée pour pouvoir pivoter autour d'un axe sensiblement confondu avec l'axe de l'alésage et apte à prendre une première position, dite position d'effacement, dans laquelle la bride peut être engagée dans la lumière et une seconde position, dite position de serrage, dans laquelle la bride est adaptée pour serrer la toile entre la face d'appui de la ferrure et une face de la bride, la bride comportant au moins un ergot radial,

caractérisée en ce que :

• l'ergot radial comprend une portée de butée agencée pour pouvoir venir en butée radiale contre un organe de butée conjuguée à partir d'une amplitude de rotation maximum définissant la position de serrage, ladite portée de butée et ledit organe de butée conjuguée étant agencés pour permettre un déplacement relatif dudit ergot par rapport audit organe de butée selon un axe parallèle à l'axe de l'alésage,
• la bride reçoit une tige traversant le corps dans ledit alésage et s'engageant axialement dans la bride, ladite tige étant adaptée pour entrainer la bride en rotation jusqu'à la position de serrage et pour, une fois l'ergot en butée, qu'une rotation complémentaire de la tige entraine le serrage de la toile entre l'ergot et la face d'appui.

To do this, the invention relates to a fitting, in particular an operating fitting, comprising:

• a body having a flat face, said support face, intended to be mounted in a wall, said canvas, of a hollow profile of an opening,
• a fastening device for the fitting on the fabric adapted to engage a light formed in the fabric and comprising at least:
  • o an orthogonal axis bore to the bearing face, passing through the body,
  • a flange adapted to pivot about an axis substantially coinciding with the axis of the bore and adapted to take a first position, said erasure position, in which the flange can be engaged in the light and a second position said clamping position, in which the flange is adapted to clamp the fabric between the bearing face of the fitting and a face of the flange, the flange comprising at least one radial lug,

characterized in that

• the radial lug comprises an abutment bearing arranged to be in radial abutment against a mating abutment member from a maximum rotation amplitude defining the clamping position, said abutment bearing surface and said abutment member being arranged to allow relative movement of said lug relative to said stop member along an axis parallel to the axis of the bore,
• the flange receives a rod passing through the body in said bore and engaging axially in the flange, said rod being adapted to drive the flange in rotation to the clamping position and, once the lug abuts, that a complementary rotation of the rod causes the tightening of the fabric between the lug and the bearing face.

By dissociating the movement of the flange in a rotation to move the lug from the erasure position to the clamping position and, when the lug is in abutment against the conjugate abutment member, in a clamping translation with an axis parallel to the axis of the bore and therefore orthogonal to the plane of the bearing face and the web, the clamping can be effected without significant effort in a plane parallel to the bearing face and therefore without risking to move the fitting. Similarly, maneuvering forces exerted in a plane parallel to the bearing face, such as opening / closing maneuver of a sliding leaf, do not tend to rotate the flange and loosen it.

Advantageously and according to the invention, the flange comprises a tapping, axis substantially coincident with the axis of the bore and the rod is a screw adapted to cooperate with said tapping to perform the clamping. In this preferred embodiment, the parts constituting the fixing device are elementary and their cost of realization particularly reduced. A single screw passing through the body and engaging in a tapping made in a substantially parallelepipedal flange is sufficient to achieve an effective fastening device.

Other embodiments of the invention are possible. For example, the flange may comprise a helical ramp, of axis substantially coincident with the axis of the bore and the rod is a smooth rod provided with a pin longer than the diameter of the rod, crossing it orthogonally at its axis and adapted to cooperate with said helical ramp to perform the clamping.

Advantageously and according to the invention, the conjugated abutment member is integral with the bearing surface of the body. In this way, the maximum amplitude of rotation of the flange between the erasing position and the clamping position is predetermined.

Alternatively or in addition, the abutment member conjugate is secured to the fabric. Thus, a rib or a wall orthogonal to the fabric can be used to limit the rotation of the flange and allow the clamping movement.

Advantageously and according to the invention, the bore passing through the body opens on the bearing face by a collar comprising at least one projecting sector so as to form an abutment member spaced apart by a predetermined angular amplitude with respect to the position erase the flange. The flange, of height less than or equal to the thickness of the fabric, allows centering and guiding the body relative to the light during installation of the fitting on the profile. The sector projecting from this flange can be obtained directly by molding during the molding of the body or by machining a flange of height greater than the thickness of the fabric, for example by milling reducing the height of the flange to the flange. exception of the projecting sector.

Advantageously and according to the invention, the fitting comprises at least two diametrically opposite flanges relative to the center of the bearing face and arranged along the major axis thereof. This arrangement is particularly advantageous for pressing the bearing face on the profile, and to absorb the operating torques, in particular the pairs developing in the plane of the profile as is the case for example with a cremone handle .

Advantageously and according to the invention, the lugs of the flanges are placed facing one another and aligned on the major axis of the bearing face in the erasing position of the flanges and are deployed on both sides. other of this axis in the tightening position. So the size of the light is minimized and the Screwing movement naturally deploys the lugs on either side of the light to allow symmetrical fixation.

The invention also relates to a fitting characterized in combination by all or some of the features mentioned above or below.

Other objects, features and advantages of the invention will become apparent from the following description and the appended drawings in which:

• the figure 1 represents a fitting, in this case a cremone handle, comprising the fixing device according to the invention opposite a hollow profile comprising a suitable light,
• the Figures 2A and 2B represent a view of the fitting according to the invention mounted on the profile, with respectively the flanges in the erasing position and in the clamping position, and
• the Figures 3A and 3B represent a detailed view of the flange mounted in the clamping position, in two separate cases of stop member.

The fitting represented in figure 1 , in this case a handle 10 of espagnolette, comprises a body 11 in which is housed a maneuvering mechanism 15 adapted to receive a square 28 of driving cremone. The handle 10 is designed to be fixed projecting on a hollow profile 24 of a sliding leaf for example and also to serve as an operating handle for the opening and / or closing of this opening by exerting on the body 11 a force substantially horizontal, parallel to the plane of the opening, in the appropriate direction for opening or closing.

The body 11 of the handle 10 has a flat face, called the bearing surface 12 materialized by a bearing edge 13 and, where appropriate, by ridges 14 reinforcements extending inside the body 11. This bearing face 12 is intended to be pressed against a wall or canvas 25 of profile 24.

At least a portion of the mechanism 15 and at least one attachment device 16 extend projecting from the bearing surface 12, towards the fabric 25 and engage therein by a light 26 cut in the fabric . The 26 is preferably oblong to allow the passage of two fasteners 16 mounted on either side of the mechanism 15.

Each fixing device 16 comprises at least one flange 17 held on the body 11 by a rod 21 passing through the body 11 by a bore 22 along an axis x orthogonal to the bearing face 12. This bore opens on the bearing face 12 by a substantially cylindrical collar 18 forming an advance relative to this face towards the fabric 25. Advantageously, the advance of the flange 18 is of the order of magnitude of the thickness of the fabric 25 and its diameter corresponds to , at an insertion clearance near, the cutting diameter of the ends of the slot 26 to allow the centering of the handle 10 on the latter.

The flange 17 comprises a substantially cylindrical head from which at least one lug 19 of substantially parallelepiped shape extends in a radial direction. The rod 21 passes through the head of the flange 17 along the axis thereof (substantially coincides with the x axis of the bore 22) and allows the flange to rotate about this axis.

Advantageously, the rod 21 is a screw whose thread cooperates with a thread formed in the head of the flange 17, the head of the screw resting in a housing of the body 11 of the fitting.

The flange 17 is adapted to take a first position, called the erasure position, represented for example by the figures 1 and 2A , in which position it can be engaged in the light 26. In the example shown, the flange 17 has only one lug 19 and its erasure position corresponds to a position in which the lug 19 is oriented in the direction of the mechanism 15. In this position, the lug is in alignment with the major axis of the light 26 and the flange 17 can be inserted into the oblong portion of the light.

Thus, as represented in Figure 2A , the fitting is mounted on the wire 25 of the profile 24 by inserting the protruding parts with respect to the bearing face 12, that is to say the mechanism 15, optionally provided with a driving square 28 and the two fixing devices 16, in the light 26 cut in the fabric.

When an operator acts on the rod 21, for example by screwing the screw, the flange 17 is rotated and rotates about the x axis, away from its erasing position. The lug 19 then moves above the fabric 25, overflowing with respect to the contour of the light 26 to a position, called the clamping position, determined by the coming into contact with an abutment bearing surface. with a mating stop member which limits the maximum rotation amplitude of the flange 17.

In a first case of use of the fixing device 16, each collar 18 has, on its frontal edge orthogonal to the x-axis, a projecting sector 23 adapted to form a conjugate abutment member integral with the bearing face of the body 11. The lug 19 then comprises an abutment bearing surface 20 (represented by the hatched area on the side of the lug 19 at the figure 3A ) in contact with the corresponding side of the projecting sector 23. Depending on the shape and position of this projecting sector, the maximum angle of rotation of the flange 17 and thus its clamping position can be predetermined. In the example shown on the Figures 2B and 3A the maximum amplitude of rotation determined by the projecting sector 23 is of the order of 90 degrees. Other amplitudes of rotation can be defined, for example 180 degrees, by shifting the sector projecting 90 degrees on the flange 18.

Of course, other means of producing a conjugate abutment member secured to the bearing face 12 may be envisaged. Thus, even in the absence of flange 18, a pin, resulting from the molding of the body 11 or reported by insertion into a housing formed therein, projecting from the bearing face 12 may form a stop member .

It should be noted that the abutment bearing surface 20 and the abutment member, whether made by the projecting sector 23 or any other means, are adapted so that once in contact with each other , the rotational movement of the flange 17 is blocked without preventing a translation movement of one relative to the other along an axis parallel to the x-axis of the bore 22. Thus, in the example shown in FIG. figure 3A , the abutment bearing surface 20 is located on the flank of the lug 19 and cooperates with the sidewall of the protruding sector 23. The rotational movement of the flange is thus blocked while allowing the relative displacement of the flange and the lug in translation along the axis of the rod 21.

Therefore, when the rod 21 is a screw, if the operator continues to screw it, the rotational movement of the flange 17 is converted into translation thereof in the direction of the web 25, thus operating a tightening the web 25 between the bearing face 12 and the heel 19a of the lug 19.

In a second case of use of the fixing device 16, the conjugate abutment member may consist of a rib 27 integral with the profile 24, as represented for example by figure 3B . This case may occur when the fitting 10 is intended to cooperate with an external mechanism mounted on the edge of the opening, in a mortise formed between two ribs.

In this case, during the rotation of the flange 17 under the action of the rod 21, the lug 19 comes into contact with a rib 27 which immobilizes it in rotation. The maximum amplitude of rotation then depends on the distance between the rib 27 and the x-axis of the bore, as well as the length of the lug. Once reached the clamping position, the rotational movement of the rod 21 causes the same manner as before the clamping of the cloth 25 between the heel 19a of the lug and the bearing face 12.

It is observed that, in the event of the presence of a rib 27 in the zone swept by the pin 19 during its movement, it is this which fulfills the role of a combined abutment member. In the absence of rib, the projecting sector 23 becomes the conjugate abutment member and determines a maximum amplitude of rotation between the erasure position of the flange and the clamping position.

Note also that the clamping force of the fabric 25 is exerted orthogonally to the plane thereof, without there being transmission of a tangential force likely to move the fitting due to the fact that the clamping occurs after the lug of the flange has come into radial abutment against the mating abutment member. Thus, the accuracy of the positioning of the fitting is ensured.

Advantageously, a fitting 10 comprises two fixing devices 16 according to the invention, preferably placed symmetrically with respect to the mechanism 15 on the major axis of the bearing face 12 of the fitting. It is then noted that the position of erasure of the flanges to minimize the size of the light 26 is to orient the lugs thereof towards each other, in the direction of the mechanism 15. When screwing the flanges, those These are rotated so that the lugs 19 unfold on either side of the major axis of symmetry of the bearing face. Once the tightening has been performed, the lugs allow the torques exerted on the fitting to be absorbed by the service maneuvers of the latter, for example the rotational torques about the axis of the mechanism 15, as well as the torques developed by them. closing or opening forces of the opening.

Of course, this description is given by way of illustrative example only and the skilled person can make many modifications without departing from the scope of the invention defined by the appended claims, such as using flanges comprising two lugs extending symmetrically with respect to the axis of the rod so as to obtain a clamping on either side of the slot 26 in the clamping position.
