Title of the invention: METHOD FOR MANUFACTURING A PROFILE PANEL AND A PANEL THUS OBTAINED

FIELD OF APPLICATION OF THE INVENTION

The present invention relates to the field of profile panels such as leaves or opening and in particular to adaptations for manufacturing a panel composed of profiled blades in the best conditions.

DESCRIPTION OF THE PRIOR ART

There are a plurality of leaf designs and among these, there are leaves formed from an assembly of profiled blades.

An example of a portal formed by such blades is described in document ER3032997. Thus, it is known to produce the leaf in blades of hollow profiles, aluminum or not. It is also known that the longitudinal edges of these blades are preformed of male and female shapes which cooperate to be kept assembled.

Screws are screwed at each end of the assembly to prevent any longitudinal sliding of the blades between them. Finally, uprights and crosspieces come by screwing to form an external frame for the blades.

A drawback to this type of configuration lies in the sliding which must be carried out to engage the longitudinal edges between them. Indeed, the assembly requires a length at least equal to twice that of a blade to allow sliding from the ends. In addition, it is necessary that a game facilitates sliding, but such a game has the consequence on gates composed of blades of great length, to be the cause of the appearance of vibrations in particular at the central part of the portal. . To overcome the drawback of vibrations, it is known to position a vertical threaded rod coming through the assembly of the blades at the central part of the gate in order to clamp the blades together on this central part.

It is understood that the integration of such a threaded rod requires an additional drilling operation extending the manufacturing time of each blade and therefore the entire portal.

In addition, to guarantee the game, it is necessary to manufacture said blades according to a precise tolerancing and with an adequate coating.

Similarly, these blades require to be put at the right length to allow the proper fixing of the uprights forming the vertical edges of the outer frame but also to avoid that a poorly lacquered end is apparent.

These various characteristics increase the cost of said blades.

Finally, the number of slides and screw connections required for the complete assembly of a gate leaf increases its duration and therefore its manufacturing cost.

DESCRIPTION OF THE INVENTION

Based on this fact, the Applicant has conducted research aimed at proposing a new method of manufacturing a panel of profiles such as a leaf for a gate, a door, a shutter or equivalent making it possible to obviate the above drawbacks identified.

An objective of the invention is to propose a leaf design which is easier to manufacture and whose manufacture can be more easily industrialized.

According to the invention, this method of manufacturing a panel of profiles formed by hollow profiled blades comprising open ends and whose longitudinal edges are positioned on each other, is remarkable in that it comprises an operation depositing a layer of adhesive on at least one longitudinal edge before assembling the blades.

The bonding provides both longitudinal and transverse fixing. It is therefore no longer necessary to create blades with complex edges ensuring and authorizing longitudinally a slide connection. The boards are placed on top of each other. Some facing surfaces of the edges must simply be in contact to allow bonding once the boards are positioned against each other. It is therefore no longer necessary to have in a long workshop to allow the edge of the first blade to slide into the edge of the other.

It is understood that this new mode of assembly between the blade of a profile panel allows the use of much less complex blades than those known in the prior art without requiring an additional assembly system. The panel obtained is not only cheaper because its constituent elements are less complex but also because it is much easier to manufacture.

To optimize said bonding, the surfaces of the longitudinal edges are preformed beforehand with protruding and / or recessed shapes so as to cooperate with recessed and / or protruding shapes preformed in the edge surface of the adjacent blade without retained in the direction perpendicular to the longitudinal axis so that the surfaces of the edges of said blades can be in contact before clinching. More simply, it is a preformation for positioning purposes of the male / female type.

More specifically, according to another particularly advantageous characteristic of the invention, at least one edge of a blade is preformed by two longitudinal ribs coming to cooperate with two longitudinal grooves preformed in an edge of the blade coming to be positioned on it, the depth of the grooves and the height of the ribs allowing contact of the surfaces from which they originate for bonding purposes. This rib / groove connection contributes to better positioning between the edges of the blades. It also offers several plans for removing the adhesive joint (s).

There is therefore no longer any functional clearance between the blades due to the presence of the adhesive joint. In addition, an adhesive ensures that the edges are in contact over the entire length. There is therefore no longer any need to pass through the central part by a threaded rod to avoid a phenomenon of vibration on the long gate aprons.

According to another particularly advantageous characteristic of the invention, the adhesive layer is placed between said two longitudinal ribs and / or between the two corresponding longitudinal grooves.

According to another particularly advantageous characteristic of the invention, the parts which cooperate together are dimensioned so as to define a reception volume of the glue less than the volume of glue applied so that, during assembly, the volume of the glue layer glue beyond the surfaces on which it is laid. This characteristic makes it possible to have an adhesive joint having a geometry adapted to the stresses liable to be subjected to the blades.

According to another particularly advantageous characteristic, the bottom of the grooves is preformed with at least one release groove constituting a retaining volume during the polymerization of the glue having flowed to the bottom of the grooves.

Thus, it is known that this type of glue has a resistance greater than a tear stress, glue joints arranged vertically for a vertical panel must therefore be preferred.

Thus, another particularly advantageous characteristic of the invention, the layer of adhesive is placed on the faces arranged opposite said two ribs.

According to another particularly advantageous characteristic of the invention, the surface disposed between the ribs is further preformed by two small projections arranged at a distance from the large projections in order to laterally retain the base of the adhesive joints placed on the faces in vis-à-vis said large projections.

In order to resist any constraint and not to change the manufacturing method according to the orientation of the blades, the geometries of the edges coming into contact are studied either to accommodate the glue in different planes during the installation of the joint of glue, or to allow the finishing of the volume of glue placed from one foreground to another plane during assembly.

According to another particularly advantageous characteristic of the invention, the edge surface disposed between each groove and coming to be positioned between the projections, is preformed so as to come into abutment against the volume of the layer of adhesive placed on the faces arranged opposite the projections so that said glue flows beyond the surface of the faces arranged opposite said projections and is introduced into the grooves.

According to another particularly advantageous characteristic of the invention, the surface disposed between the ribs is preformed by two small projections arranged at a distance from the ribs in order to laterally retain the base of the layer of adhesive placed on the facing faces. with respect to said ribs.

According to another particularly advantageous characteristic of the invention, the surface disposed between the grooves and coming to bear against the surface is preformed with projecting edges coming during assembly, in the volume occupied by the adhesive layer placed on the facing faces of said ribs.

According to another particularly advantageous characteristic of the invention, the edge surface disposed between each groove has a height different from that of the remaining edge portions so that once in abutment on the edge surface disposed between the projections , the latter are not in abutment against the bottom of the grooves, which facilitates the finishing.

According to another particularly advantageous characteristic, said U-shaped edge profile is glued to the edge of the profile panel. In order to optimize this bonded solution, the method of the invention comprises the manufacture of U-shaped edge profiles which adhere to the edges of the profile panel, the U-shaped profile is preformed so as to have a bulge at the distal end of the branches. of U to form a spacing corresponding to the thickness of the blades, the glue being placed on the internal surface of the branches arranged between the base of the U and said bulge, the spacing between said internal surfaces being greater than the thickness of said blades so to welcome said glue. By providing a sufficiently large depth of U, it is not necessary to lengthen the blade profiles as for the previous characteristic using a retaining module.

The polymerization of the adhesive can be carried out hot or cold. In addition, the glue can be applied in several stages and be different depending on the stages. Thus, according to another particularly advantageous characteristic of the invention, at least two types of adhesive are applied:

- A first type of rapid polymerization, in order to guarantee the holding of the blades together during the manufacture of the panel,

- A second type of slower polymerization intended to guarantee the holding of the blades together during the use of the profile panel.

According to another particularly advantageous characteristic of the invention, the method also comprises the following operation:

Clinching of the open ends of said blades for fixing purposes one on the other of said longitudinal edges.

Clinching here completes the bonding. Not only does it optimize the support of the blades between them but it also ensures the maintenance of the blades during the polymerization of the adhesive.

According to a preferred embodiment, two clinching points are made at each end of the assembled longitudinal edges.

Associated with clinching, the method of the invention comprises a punching operation at each end of the longitudinal edges assembled to obtain an orifice passing through said longitudinal edges of two adjacent blades. This hole will allow the positioning of an assembly element for the edges of the panel. The same robotic arm cooperating with the appropriate tools can implement clinching and punching.

Thus, to complete the bonding or as an alternative for fixing the panel edge profiles, the method is also remarkable in that it comprises the positioning of a module for retaining panel edge profiles on the ends of the blades, the retaining module comprising:

- On the one hand, two projections forming a clamp pinching the ends of the assembled edges,

- on the other hand, a flat part perpendicular to said projections and with which cooperates by sliding a preformed edge profile for this purpose.

It is understood that this characteristic participates in one of the objectives of the invention which is to provide a panel without assembly screws and therefore without the operations necessary for their implementation.

According to another particularly advantageous characteristic of the invention, the free ends of the projections of said clamp are preformed in a projecting shape cooperating with the punched orifice to form a clip assembly.

According to another particularly advantageous characteristic of the invention, the punching is carried out from a rib linked to the theoretical medium of the blade. The consequence of this characteristic is that it does not take into account the vagaries of the lengths of the blades leaving the production line. Thus, the retaining module has its perpendicular plane part coplanar with the other retaining modules. In addition, by providing a profile for the U-shaped edge profile with large lateral branches, such a characteristic has the advantage of not having to cut the blades to length.

For this additional reason, the blades and therefore the profile panel obtained have a lower cost than that of the means of the prior art.

According to another particularly advantageous characteristic of the invention, the edge surface disposed between each groove has a height different from that of the remaining edge portions so that once in abutment on the edge surface disposed between the projections , the faces of the blades are not contiguous and allow the reception in the longitudinal inter-blade space created of a decorative element coming from the outside to be introduced into said space. Maintaining in position can be implemented by friction and / or by bonding.

The invention also relates to the profile panel, the gate leaf or the leaf obtained according to the characteristics of the process described above, characteristics taken together, separately or in groups.

Thus, according to a particularly advantageous characteristic, the profile panel or leaf obtained according to the manufacturing process is remarkable in that it comprises a plurality of hollow profiled aluminum blades whose preformed edges of complementary shapes are assembled by clinching and by collage.

The fundamental concepts of the invention just explained above in their most basic form, other details and characteristics will emerge more clearly on reading the description which follows and with reference to the accompanying drawings, giving by way of nonlimiting examples, several embodiments of a method for producing a gate leaf and a leaf thus obtained in accordance with the invention.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

As illustrated in the drawing of Figure 1, the portal referenced P as a whole is of the swing leaf type and formed of two leaves movable in rotation.

These gate leaves P comprise a plurality of hollow profiled blades 100 of aluminum arranged horizontally one on the other in the same vertical plane by being assembled by their edges. A frame 200 comprising crosspieces and uprights completes the assembly on the lateral vertical edges and on the top and bottom horizontal edges of the assembly formed by the blades 100.

As illustrated in the drawing in Figure 2, the profile of the blade 100 takes the form of a vertical rectangle whose short horizontal sides lower 110 and upper 120 are the edges of the blade 100 and whose large vertical sides 130 and 140 are the visible vertical faces forming the vertical walls of the leaf.

The blades 100 are assembled one on the other at their edges.

To ensure positioning, the upper longitudinal edge formed by the upper side 120 is preformed by two longitudinal parallel grooves 121 and 122 while the lower longitudinal edge formed by the lower side 110 is preformed by two longitudinal parallel ribs 111 and 112 of spacing and height adapted to collaborate with the ribs of the adjacent blade. These protruding and recessed shapes do not constitute a vertical restraint and therefore allow stacking.

An internal partition 150 braces the long vertical sides 130 and 140.

According to the preferred but nonlimiting embodiment illustrated, the surface 123 of the lower edge 110 located between the two grooves 121 and 122 protrudes relative to the rest of the edge surface so that once the surface 123 resting on the surface 113 located between the ribs 112 and 111 of the adjacent blade, the edges of the edges are not covered by the edges of the edge of the adjacent blade. A horizontal spacing is then visible between the blades forming the leaf.

As illustrated in the drawing of Figure 3, these surfaces 113 and / or 123 are those which receive a bead of adhesive C which remains enclosed between the ribs once the blades 100 stacked.

As illustrated in the drawing in FIG. 4, the two blades 100 are assembled by clinching at two points 310 and 320 of their edge coming into contact at the surfaces 113 and 123. It is clinching pliers ( not shown) which provides the necessary deformation at the two ends of the blades 100.

We understand that this method of assembly facilitates the automation of operations. Stacking, laying of the adhesive bead C and clinching can thus be carried out on an automated assembly line.

Simultaneously or in addition to the clinching operation, a punching operation comes to drill a through hole 330 in the clinched surfaces, this through hole 330 will be used to position at regular intervals (cf. FIG. 5) the retaining modules 400 of the uprights 500 (see Figures 6 and 7) forming the frame. This retention of the amounts 500 on the ends of the blades 100 is therefore implemented without screwing.

As illustrated in the drawings of FIGS. 4 and 8, the retaining module 400 comprises:

- on the one hand, two horizontal projections 410 and 420 forming a clamp pinching the ends of the clinched edges,

- On the other hand, a flat part 430 perpendicular to said projections 410 and 420 and with which the profile of the upright 500 cooperates by sliding. To do this as illustrated in the drawing in FIG. 7, said profile 500 is preformed d 'a retaining area 510 forming a slide for said portion 430 of the retaining module 400. In order to provide precise positioning of the retaining module 400 in the upright 500 the latter is drilled at regular intervals in the bottom of the retaining area 510 d '' a concave shape 511 with which cooperates a corresponding convex shape 440 mounted on an elastic part to allow the sliding of the retention module 400 in the retention area 510 and its stop in position when the convex shape 440 is positioned in the concave shape 511.

In addition, the free ends of the projections 410 and 420 of said clamp are preformed in a projecting shape cooperating with the hole 330 punched to form a clip assembly.

As illustrated in the drawing in FIG. 5, three retaining modules 400 ensure the fixing of an upright 500 on each side of the leaf.

As illustrated in the drawing in Figure 7, the amount 500 has a profile allowing it to engage over a great depth on the ends of the blades 100. This characteristic makes it possible to take into account the variations in length of the blades and avoids a lengthening operation.

As illustrated in the drawing in Figure 9, the blade 100 located at the bottom of the leaf is the subject of an additional machining operation to create the openings 160 necessary for the reception of casters 600.

The drawings of Figures 10 to 13 illustrate another embodiment of the process and the leaf optimized for implementing the bonding.

Thus, as illustrated in the drawing in Figure 10, the adhesive joint C 'is placed on the faces arranged opposite the two longitudinal vertical ribs 111' and 112 '. This characteristic makes it possible to have an adhesive joint having an orientation that is most suited to the stresses liable to be subjected to the blades.

In order to circumscribe the adhesive joint C 'over a certain thickness before assembly, the surface 110' is further preformed with two small projections 114 'and 115' arranged at a distance from the large projections 112 'and 111' in order to laterally retain the base of the adhesive joints C 'placed on the opposite faces of said large projections.

As illustrated, the parts coming to cooperate together are dimensioned so as to define a glue reception volume less than the volume of glue applied so that, during assembly as illustrated in the drawing in FIG. 11, the volume of the glue joint flowing beyond the surfaces on which it is laid.

To allow this fining of the adhesive, the edge surface 120 ′ disposed between the grooves 121 ′ and 122 ′ has a height different from that of the remaining edge portions so that once it rests on the edge surface 110 'disposed between the projections 111' and 112 ', the latter are not in abutment against the bottom of the grooves thus allowing the glue to pass. This difference in height also makes it possible to create a longitudinal space E on the two faces of the leaf. The outer wall of the grooves prevents the glue from ending up on the outside.

To participate in this glue creep, the surface 120 'disposed between the grooves 121' and 122 'and coming to bear against the surface 110' is preformed with projecting edges 124 'and 125' coming during the 'assembly in the volume occupied by the glue joints C'.

In order to retain the glue, the bottom of the grooves 121 ′ and 122 ’is preformed by at least one release groove constituting a retaining volume during the polymerization of the glue having flowed to the bottom of the grooves.

As illustrated in the drawing in Figure 12, the space E is a longitudinal groove disposed on each side of the leaf between each blade capable of receiving a decoration element here a bar B adopting a T profile whose central bar is received in space E and can be retained by friction and / or by bonding.

As illustrated in the drawing of Figure 13, in addition to or as an alternative to the binding illustrated in the drawings of Figures 4 to 8, the U-shaped edge profile 500 'is glued to the edge of the profile panel formed by blades 100. The U profile 500 'is preformed so as to have a bulge 510' at the distal end of the branches of the U to form a spacing corresponding to the thickness of the blades 100, the adhesive C '' being placed on the internal surface branches arranged between the base of the U 520 'and said bulge 510', the spacing between said internal surfaces being greater than the thickness of said blades in order to accommodate said adhesive C ”. The depth of this U-shaped profile is defined so that it can be installed despite variations in the length of the profiled blades and to cover any end defects. No lengthening is therefore necessary.

It is understood that the profile panel and its manufacturing process, which have just been described and shown above, have been for the purpose of disclosure rather than limitation. Of course, various arrangements, modifications and improvements could be made to the above examples, without going beyond the ambit of the invention.
