Description

The present invention relates to an opening or sleeping profile, especially for window, door, or other, aluminum, plastic or other.

Already known from the prior art openings or window frames or door have a frame surrounding a glass panel. Generally, this type of frame has an outer or inner peripheral wall on which is formed a longitudinal guide groove for installing a fitting. The fitting is composed of an accessory connected, for example, to control elements (handle) or opening / closing, and a transmission rod capable of transmitting movements from the control elements. Normally, the dimensions of the opening frame and / or frame may vary depending on the model, while the dimensions of the rods and accessories are generally standardized. Therefore, in the prior art, when mounting an accessory on the groove, it is necessary to cut the transmission rod and previously drill a hole on the transmission rod to attach it to the accessory. Adapting a rod to the dimensions of the sash frame and / or frame requires a relatively long time.

In order to remedy this problem, the patent document EP 1 867 821 A1 , describes a fitting having a rod and an accessory. This fitting comprises a fixing means for fixing the accessory on the rod. This fastening means comprises a screw having an end which is capable of piercing an orifice on the rod, which allows a quick adjustment of the accessory on the rod at the time of assembly. The manufacturing time is then shortened.

However, when drilling the rod, waste tends to occur. Although this document describes a rod arranged so that this waste is retained between the side walls of the rod, it There is a risk of waste falling on the groove and thus blocking the sliding of the transmission rod.

There is therefore a need for an assembly to reconcile simplicity and reliability.

The present invention achieves its goal by providing an opening profile or frame on which is formed at least one longitudinal guide groove. The profile comprises: a transmission rod intended to be housed inside the guide groove in a translational manner and comprising a central portion which extends longitudinally over the entire length of the transmission rod, an accessory adapted to engage with the transmission rod for actuating the transmission rod, for example a trainer or a functional accessory; and percussion attachment means for attaching the accessory to the transmission rod. This central portion of the transmission rod defines: an upper wall, intended to be pierced by the percussion means, and on either side of the upper wall, two side walls forming with this upper wall a channel capable of receiving at at least a part of the fixing means and extending longitudinally over the entire length of the central portion. According to the invention, the central portion further has a bottom portion connecting the side walls and extending the entire length of the central portion, so as to close said longitudinal channel in cross section.

Thus, a characteristic of the invention lies in the fact that the upper wall, the side walls and the bottom portion of the central portion of the transmission rod together form a longitudinal channel closed on a cross section. This closed longitudinal channel makes it possible to retain waste generated during an attachment by percussion of the transmission rod, inside the channel. The longitudinal channel may optionally be closed longitudinally, for example by closing the longitudinal ends of the transmission rod and / or by two accessories to retain waste between them, inside the canal. Also, it is possible to prevent blocking of the sliding of the transmission rod.

In addition, the longitudinal channel formed by the upper wall and the side walls of the transmission rod ensures sufficient space to receive the fastening means.

The invention is not limited to a particular form of the fastening means, insofar as this means makes it possible to rigidly fix the accessory on the percussion transmission rod. For example, the attachment may be effected by means of a screw, or a punch.

For the purposes of the present invention, the accessory may be any part adapted to cooperate with the transmission rod as long as it can hold the transmission rod inside the groove and without preventing the sliding of the rod. The accessory can then prevent any disengagement of the rod of the groove.

In addition, with the profile described above, the adjustment of the accessory on the transmission rod can be performed at the time of assembly using the fastening means. The editing time is then shortened.

Preferably, the side walls of the transmission rod may be substantially inclined towards the upper wall so that said central portion defines, in cross-section, a trapezoidal profile, which gives the transmission rod a certain compressive strength and to wear.

Advantageously, the fixing means may comprise a screw having an end capable of piercing said upper wall of the central portion. This feature allows simple attachment of the transmission rod and accessory. An orifice may be provided on the accessory and the fastening means may comprise a screw having a threaded rod which terminates in a free end capable of piercing the transmission rod. In this case, the end of the screw is first introduced through the orifice of the accessory, and then screwed until the screw opens on the central portion of said transmission rod.

Advantageously, the end of the screw may be located between the upper wall and the bottom portion. Therefore, the waste generated at the time of drilling by the screw are retained in the closed longitudinal channel.

Preferably, the guide groove may define a bottom wall and two inner side walls raised with respect to the bottom wall.

The groove may advantageously further define two flanges oriented toward each other, facing the bottom portion, and extending parallel or substantially parallel to the bottom portion from two respective ends of the inner side walls.

Advantageously, the guide groove may have two flanges, each erected relative to a respective inner side wall of the guide groove. These flanges extend longitudinally over the entire length of the guide groove. The flanges each have a free end remote from the corresponding inner side wall of the guide groove. These two free ends together define an insertion space for the transmission rod.

Preferably, the transmission rod further has two side portions located on sides on either side of the central portion. These lateral parts extend longitudinally over the entire length. These lateral parts allow to participate in the recentering, and when they are sufficiently extended laterally to come under the edges of the groove, to maintain the rod in the groove before the installation of the accessory.

The side walls of the central portion may have an upper portion adjacent to the top wall and a lower portion adjacent to the bottom portion. Advantageously, the lateral walls extend vertically from said lower part of the lateral wall over the entire length of the transmission rod, and the lateral parts extend laterally from said lower part of the lateral wall over the entire length of the rod transmission. In other words, the central portion extends vertically protruding from the side portions, and this over the entire length of the rod.

The accessory can be arranged not only to easily receive the transmission rod but also to hold the rod relatively firmly in the guide groove. In this case, the accessory can define a receiving groove, extending longitudinally, in which is intended to be embedded in the central portion of the transmission rod.

For the purposes of the present invention, the term "vertical" does not necessarily mean the direction following gravity, but must be determined relative to the bottom wall of the guide groove.

Advantageously, the transmission rod may have two opposite lateral ends and the accessory may have two lateral ends. Each of the lateral ends of the accessory advantageously defines a retaining rib extending longitudinally and capable of coming between a corresponding lateral end of the transmission rod and the corresponding inner lateral wall of the guide groove. Thus, the refocusing of the transmission rod inside the guide groove is ensured.

Preferably, the bottom wall of the guide groove may have a bottom groove formed on the bottom wall of the guide groove along the entire length of the guide groove. The guide groove may define another groove formed on the bottom wall, this other groove making it possible to ensure a space below said transmission rod (that is to say between the bottom of the groove and the rod) . Thanks to this space, the fluid sliding of the transmission rod is ensured even if the fastening means opens completely onto the transmission rod so as to form a waste.

The bottom portion may have a stud to be located between said bottom portion and said bottom groove. This nipple can in particular extend longitudinally over the entire length of the bottom part of the central part. Thus, the pin can facilitate the refocusing of the rod inside the groove during installation of the rod.

Typically, the guide groove has an identical cross section along the entire length.

Advantageously, the transmission rod may have, in cross section, a greater distance T4 between the two opposite opposite end ends over the entire length.

Advantageously, the distance T4 can fulfill the following conditions: T4≤R1; T4≤R3; and R2≤T4, to the machining accuracy, wherein: R1 is the distance, in a cross section, between the inner side walls of the guide groove; R2 is the distance, in a cross section, between said free ends of the flanges; and R3 is the distance, in a cross-section, between the free end of one of the flanges and an intersection formed by the bottom wall and the inner side wall of the guide groove adjacent to the other flange.

Thus, the transmission rod is both able to be inserted in front and both ends are housed inside the guide groove. Therefore, it is not necessary to provide a clipping on the accessory to ensure the attachment of the fitting on the guide groove unlike that disclosed in the application EP 1 867 821 A1 . In addition, the transmission rod and the guide groove may have a substantially symmetrical shape with respect to a longitudinal and vertical plane. The invention can thus limit the number of references for accessories.

Moreover, the fact that the transmission rod can be installed on the front allows not only simplify the assembly but also reduce the mounting space.

The present invention also relates to a method of mounting a profile comprising a central portion which extends longitudinally over the entire length of the transmission rod, this central portion defining an upper wall, a lower wall facing the upper wall, and, on either side of these upper and lower walls, two side walls defining with these upper and lower walls a channel extending longitudinally along the entire length of the central portion and closed in cross section, comprising the following steps: the transmission rod is inserted inside said guide groove, advantageously on the front; installing, advantageously by lateral sliding, the accessory on the transmission rod; and immobilizing the accessory on the transmission rod by a percussion attachment means, perforating the upper surface of the closed channel.

This method therefore ensures a simple mounting of the accessory and the transmission rod while avoiding blocking the sliding of the transmission rod.

Other features and advantages of the invention will emerge on reading the following description of a particular embodiment of the invention, given by way of indication but not limitation, with reference to the accompanying drawings in which:

• the Figure 1 is a perspective view of an exemplary profile according to an embodiment of the invention;

The figure 1 shows a profile 1 of opening or sleeping including window or door of aluminum or plastic. On the profile 1 is formed a longitudinal guide groove 3 extending in a longitudinal direction (represented by the double arrow D).

The longitudinal guide groove 3 has a longitudinal end 2.

The profile 1 further comprises a transmission rod 5 housed inside the guide groove 3, and an accessory, or actuating element 7 cooperating with the transmission rod 5.

Preferably, the guide groove 3, the transmission rod, and the accessory 7 are formed of a metallic material.

The accessory 7 here has a longitudinal main body 8 defining lateral ends 35, 35 '(see FIG. figure 2 ). The lateral ends 35, 35 'of the accessory are engaged, with the transmission rod 5 in the guide groove 3 in a translationally mobile manner.

The transmission rod 5 and the accessory 7 are then fixed one on the other by means of a fixing means comprising a screw 10. In this case, the main body of the accessory 7 defines a through hole, in which is received a screw, as explained below.

The figure 2 is a cross-sectional view of the profile of the figure 1 along the line A-A '.

The guide groove 3 has a bottom wall 9 and two inner side walls 11, 11 'raised with respect to the bottom wall 9.

The guide groove 3 further has two flanges 13, 13 'extending perpendicular to the side walls 11, 11'. Each flanges 13, 13 'define a lower inner surface 15, 15' facing the bottom wall 9.

The inner side walls 11, 11 'each have a lower end 17, 17' adjacent to the bottom wall 9 and an upper end 19, 19 'situated opposite the bottom wall 9.

The flanges 13, 13 'each having a free end 21, 21' distant from the upper end 19, 19 'of the corresponding inner side wall 11, 11'. These free ends 21, 21 'together define an insertion space 41 (see FIG. figure 4 ) capable of receiving the transmission rod 5.

The bottom wall 9 has a bottom groove 12 defined over the entire length of the groove.

The transmission rod 5 has a central portion 25 extending longitudinally along the entire length and two lateral portions 23, 23 'situated on opposite sides with respect to the central portion 25. The lateral portions 23, 23' of the rod transmission 5 have two ends 31, 31 '.

The central portion 25 has an upper wall 27 and two side walls 33, 33 '. Each of these side walls 33, 33 'connects the upper wall 27 to the corresponding lateral part 23, 23'. The central portion 25 further has a bottom portion 29 connecting the two side portions 23, 23 '. The sidewalls of said central portion 25 each have an upper portion 34, 34 'adjacent to the top wall 27 and a lower portion 36, 36' adjacent to the bottom portion 29. Each of the side portions 23, 23 'extend laterally from the corresponding lower part 36, 36 'along the entire length of said transmission rod 5.

Thus, the assembly consisting of the upper wall 27, the side walls 33, 33 'and the bottom portion 29 form a closed longitudinal channel.

The side walls 33, 33 'are substantially inclined towards the upper wall 27 so that the central portion defines a trapezoidal profile in cross section. This shape of the central portion 25 allows the transmission rod 5 a relative resistance to compression and wear.

The accessory 7 defines a receiving groove 32 in which is intended to fit the central part 25 of the transmission rod 5. The lateral ends 35, 35 'of the accessory 7 each have a retaining rib 37, 37 'which is framing the corresponding lateral ends 31, 31' of the transmission rod 5. These retaining ribs 37, 37 'allow to center the transmission rod 5 with respect to the guide groove 3. The set of ends the lateral 35, 35 'of the accessory 7 and the lateral ends 31, 31' of the transmission rod 5 abut against the lower internal surfaces 15, 15 'of the flanges 13, 13' when driving the accessory 7 to the outside of the guide groove 3. The assembly of the transmission rod 5 and the accessory 7 can then avoid disengaging from the guide groove 3.

As shown in figure 2 , the screw 10 opens on the upper wall 27 of the central portion 25 through the accessory.

With reference to the figure 3 , the guide groove has an identical cross section over the entire length. In addition, the transmission rod 5 has, in cross section, the same greater distance T4 between said two opposite lateral ends 31, 31 'over the entire length.

• R1 est la distance entre les extrémités inférieures 17, 17' des parois latérales interne 11, 11',
• R2 est une distance entre les extrémités libres 21, 21' des rebords 13, 13',
• R3 est la distance entre l'extrémité libre 21, 21' de l'un des rebords 13' et une intersection 39 formée par la paroi de fond 9 et la paroi latérale interne 11 adjacente à l'autre rebord 13.

The distances R1, R2, R3 and T4 fulfill the following conditions: T4≤R1; T4≤R3; and R2≤T4 in which, on a cross section:

• R1 is the distance between the lower ends 17, 17 'of the inner side walls 11, 11',
• R2 is a distance between the free ends 21, 21 'of the flanges 13, 13',
• R3 is the distance between the free end 21, 21 'of one of the flanges 13' and an intersection 39 formed by the bottom wall 9 and the inner side wall 11 adjacent to the other flange 13.

These conditions are met to the near machining accuracy. That is, since T4 R R1, the transmission rod 5 can slide inside the groove, since T4 R R3, the transmission rod 5 can be inserted through the insertion space 41 , and since R2≤T4, both ends of the transmission rod can be retained by the lower inner surfaces 15, 15 'of the flanges 13, 13'. These dimensions therefore make it possible, not only to insert the transmission rod 5 via the insertion space 41, that is to say on the front, but also to fully accommodate the two lateral ends 31, 31 'of the rod transmission 5 within said guide groove 3 and below the flanges 13, 13 '.

We will now describe, with reference to Figures 1, 2 and 4 , a way of mounting profile 1.

As shown in figure 4 firstly, the transmission rod 5 is inserted through one of the lateral ends 31 'into the guide groove 3 via the insertion space 41 until the lateral end 31 'is applied against the intersection 39. Then, the other lateral end 31 is also inserted inside the guiding groove 3. Once the lateral ends 31, 31' are completely housed inside. of the guide groove 3, the accessory 7 is inserted through the longitudinal end 2 so that each of the retaining ribs 37, 37 'slides between the lateral end 31, 31' and the inner side wall 11, 11 'of the guide groove, then the accessory is driven in translation until it finds its final position.

Since the accessory 7 generally has a relatively small length, the accessory 7 can be inserted through the entrance longitudinal of the transmission rod 5 and slidably installed laterally inside the guide groove 3, without causing significant loss of time and space.

Then, a screw 10 is introduced having a threaded rod whose free end is concave tip (not shown), inside the orifice 14 previously provided on the accessory, and is screwed until the end of the screw 10 arrives at the transmission rod 5. In an alternative embodiment and not shown, the screw 10 can be pre-assembled on the accessory 7. It continues to screw so that the screw 10 pierces the wall upper 27 of the central portion 25 to form a through hole. Once pierced, the transmission rod 5 is then fixed to the accessory 7 rigidly. When drilling the upper wall, waste is produced. However, the closed longitudinal channel makes it possible to retain this waste inside. Therefore, it is possible to prevent blockage of the sliding of the transmission rod.
Finally, figure 5 shows an example of a transmission rod according to a second embodiment of the invention. This mode differs from the first mode in that the transmission rod 5 'is provided with a pin 43 below the bottom portion 29'. Thanks to the pin 43, the transmission rod 5 will not fall into the bottom groove 12 during assembly. In addition, this stud facilitates the centering of the transmission rod 5 inside the guide groove 3.
