Description

process for manufacturing a panel, in particular for light construction and panel and light construction

The present invention relates to a process for manufacturing a panel, in particular for the production of light construction, such as a fence, claustra, pergola, as well as the panel and the light construction obtained, in particular by the implementation of said method.

It relates in particular to a method of manufacturing a panel of the aforementioned type comprising, in the mounted state, a contiguous or openwork stack of slats and two end uprights between which said stack extends.

Such a panel is known. However, until now such a panel has not been satisfactory in terms of dimensional stability, in particular when the slats are wooden slats, so that such a panel cannot be used to form a line of panels.

An object of the invention is to provide a panel whose design allows dimensional stability without harming the aesthetics of said panel.

To this end, the subject of the invention is a process for manufacturing a panel, in particular for the production of light construction, such as a fence, claustra, pergola, said panel comprising at least one contiguous or openwork stack of slats and two end posts between which said blade stack extends, characterized in that each end post comprising a plurality of profiles configured to be arranged next to each other when assembled, said method comprises , for each end upright, a step of fixing by at least one connecting member of each slat to one of the sections of said end upright and a step of masking the connecting members by the other or another of the profiles of said end upright in the assembled state of said profiles of said end upright between them. The use of members for connecting each slat to at least one of the profiles of each end upright makes it possible to eliminate the dimensional variations of the slats, in particular in the direction of the height of the panel in the upright state of the panel. The use of a second section makes it easy and in a short time to mask said connecting members.

According to one mode of implementation of the method, the profile with the function of masking the connecting members of said end upright is coupled to the other or to at least one of the other profiles of the end upright by a connection to sliding interlock. This method of assembling the profiles by simple sliding interlocking allows rapid assembly of the profiles together.

According to one embodiment of the method, the profile of the end upright to which the slats can be coupled by a connecting member is attached to another of the profiles of the end upright and is held assembled to said profile by the profile with function masking in the assembled state of said profiles. The masking profile is thus a versatile profile with masking and locking function.

According to one mode of implementation of the method, one of the profiles of the end upright has a plane of symmetry and two longitudinal grooves called first longitudinal groove and second longitudinal groove, these first and second longitudinal grooves each provided with an opening longitudinal being arranged on either side of the plane of symmetry. The presence of two symmetrical longitudinal grooves makes it possible to use the profile for making the right or left end upright of said panel. In addition, the presence of two longitudinal grooves facilitates the production of a line of panels, the second groove can also be used to receive a filling.

According to one embodiment of the method, the longitudinal opening of the first longitudinal groove of said section is an opening through which one end of each blade to be coupled to one of the sections can be inserted before the step of fixing the blade.

According to one mode of implementation of the method, the opening of the second longitudinal groove of the profile is an opening that can be closed by at least one of the other profiles of the end upright, this closure profile being, in the state assembly of said profiles, coupled to the grooved profile by a profile of the end upright of a shape seen in cross section similar or identical to that of the profile with masking function. This second groove can be used to receive a finishing profile. This finishing profile can be kept assembled with the other profiles of the end upright using the same type of profile as that used to maintain the profile to which the blades are coupled. This results in a simplification of the assembly and a reduction in the type of profiles.

According to one mode of implementation of the method, at least one of the longitudinal grooves of the grooved profile is delimited by an axial cavity passing through the profile, this cavity being, seen in cross section, of generally quadrangular shape and the opening of the groove is formed in one of the open angles of said cavity. This configuration allows easy angular orientation of the slats inside the longitudinal groove of the profile.

According to one mode of implementation of the method, at least one of the openings of the longitudinal grooves of said profile with grooves of the end upright has edges, one of which extends set back from the profile with a masking function at the assembled state of said profiles. This arrangement makes it possible, depending on the angular orientation of the slats inside the groove, to use at least part of the masking profile as a support surface for the slats.

The invention also relates to a panel, in particular for the production of light construction, such as a fence, screen wall, pergola, said panel comprising at least one contiguous stack or slatted planks and two end uprights between which said stack of slats extends, characterized in that each end upright comprises several sections arranged in the assembled state next to one another, and in that for each end upright each slat is fixed to one of the profiles of said end upright by at least one connecting member and in that the other or another of the profiles of said end upright conceals said connecting members in the assembled state of said profiles of said upright end between them. This panel, which can be obtained by implementing the aforementioned manufacturing process, therefore has the advantage of being dimensionally stable in the direction of the height of the panel in the upright state without this affecting its aesthetics.

According to one embodiment of the invention, the profile with the function of masking the connecting members of said end upright is coupled to the other or to at least one of the other profiles of the end upright by a connection to sliding interlock.

According to one embodiment of the invention, one of the profiles of the end upright has a plane of symmetry and two longitudinal grooves called first longitudinal groove and second longitudinal groove, these first and second longitudinal grooves, each provided with a longitudinal opening, being arranged on either side of the plane of symmetry.

According to one embodiment of the invention, the longitudinal opening of the first longitudinal groove of said section is an opening through which one end of each blade to be coupled is inserted.

According to one embodiment of the invention, the opening of the second longitudinal groove of said profile is an opening that can be closed by at least one of the other profiles of the end upright, this closure profile being, in the state assembly of said profiles, maintained in the state coupled to the grooved profile by a profile of the shaped end upright, seen in cross section, similar or identical to that of the profile with masking function.

According to one embodiment of the invention, at least one of the longitudinal grooves of said profile is delimited by an axial cavity passing through the profile, this cavity being, seen in cross section, of generally quadrangular shape, and the opening of the groove is made in one of the open corners of said cavity.

The invention also relates to a lightweight construction, such as a fence, comprising a plurality of panels formed respectively of a contiguous stack or slatted slats and two end uprights between which said stack extends , said panels being assembled to each other by their end uprights, characterized in that at least one of the panels is of the aforementioned type.

As mentioned above, the subject of the invention is a method for manufacturing a panel 1 and the panel 1 which may result from the implementation of said method, this panel 1 possibly conforming to that shown in FIG. 1. This panel 1 is a panel more particularly intended for the production of a lightweight construction such as a fence of the type shown in figure 9. In this case, the panels can be arranged to form an alignment of panels 1.

Such a panel 1 comprises, in the manufactured state, at least one contiguous or slatted stack of slats 2, preferably made of wood, and two end uprights 3, preferably made of metal, in particular aluminum, between which said blade stack 2 extends. Each end upright 3 comprises several sections that can be assembled together and configured to be arranged, side by side, that is to say next to each other, in the assembled state. Each profile is in the form of an elongated body. In the assembled state, said profiles of the upright are generally not disassemblable under the effect of traction exerted on each profile in a direction transverse to the longitudinal axis of the profile. The number of sections may vary depending on the design of each upright 3 end. At a minimum, each end upright 3 comprises at least two profiles, namely a profile 4 to which the blades 2 are coupleable by means of at least one connecting member 7 and a masking profile of said connecting members 7, this masking section being shown at 6 in the figures. This masking profile 6 is, independently of the design of the rest of the end upright 3, coupled to the other 4 or at least to one of the other profiles of the end upright 3 by a sliding interlocking connection 8. To this end, this section 6 has externally at least one longitudinal groove forming a rail capable of cooperating with at least one slide of the other or at least one of the other sections of the end upright. This masking profile 6 is thus for its assembly positioned at least partially in the extension of the profile 4 to which it must be assembled as illustrated in FIG. 4 and then slidably moved along the profile of the upright 3 at the end to which it must be assembled by this connection 8 sliding interlocking. This results in a simplicity of assembly of profile 6 for masking.

Generally, each end post 3 also comprises at least one of these profiles shown at 4 in the figures which has a plane of symmetry and two longitudinal grooves called first longitudinal groove 9 and second longitudinal groove 11. This section 4 is called grooved section. These first and second longitudinal grooves are each provided with a longitudinal opening and are arranged on either side of the plane of symmetry. The longitudinal opening of the first groove 9 is shown at 10 in the figures and its edges at 100, 101 while the opening of the second longitudinal groove 11 is shown at 15 in the figures and its edges at 150, 151 (Figure 6) .

The grooved profile 4 can be the profile of the end upright 3 to which the slats 2 of the stack can be directly coupled, as in the example shown in FIGS. 1 to 7. Alternatively, and as illustrated in FIG. 8, the profile 4 with grooves can be used to receive another profile shown at 5 in FIG. 8, the blades 2 of the stack of blades 2 each being coupled to this profile 5 attached by a connecting member 7, such as a screw. In this embodiment, the added profile 5 which is a profile with a U-shaped cross-section with external longitudinal flanges can be kept assembled to the grooved profile 4 on which it is attached by the masking profile 6. This retention can take place by cooperation of complementary geometric shapes between said sections. Thus, in the assembled state of the profiles of the end upright 3, the profile 5 attached to another of the profiles of the end upright, for example the profile 4 with grooves, is held to this said profile by the profile 6 with the function of masking so that any disassembly of the profile 5 added from the other profiles of the upright by movement in a direction transverse to the longitudinal axis of said profile is prevented.

The profile 4 with grooves can therefore be either intended to be coupled directly to the blades 2, or intended to be assembled to a profile 5 to which the blades 2 are coupled. Independently of the design of this profile 4 with grooves, the longitudinal opening 10 of the first longitudinal groove 9 of said profile 4 is an opening 10 through which one end of each blade 2 to be coupled to one of the profiles is insertable before the fixing step of the blade 2 to said profile. Thus, in practice, when the profile 4 with grooves conforms to Figures 1 to 7, one of the ends of each blade is inserted directly into said longitudinal groove 9 of the profile 4 with grooves and a connecting member 7, such as a screw, couple for example by screwing the end of the blade 2 to said profile 4 with grooves. The masking section 6, once assembled to the grooved section 4, only serves to mask the connecting members 7 which form an alignment of connecting members 7 along the profile.

When the grooved profile 4 conforms to FIG. 8, the profile 5, for example U-shaped, is fitted into one of the longitudinal grooves of the grooved profile 4 and one end of each strip 2 of the stack is inserted between the branches of the U and fixed to said branch of the U by a connecting member 7, such as a screw, passing through a branch of the U to be housed in the strip 2. The masking profile 6 which is then attached and assembled to the least to the profile 4 with grooves by sliding interlocking also serves as a retaining profile of the profile 5 attached to the profile 4 with groove. When the end upright 3 is not an amount intended to be common to two similar panels, the opening 15 of the second longitudinal groove 11 of the grooved profile 4 can be closed off by one of the profiles of the upright 3 d 'end. This profile, shown at 12 in Figures 5 and 6, is held in the assembled state to the grooved profile 4 by a profile 13 of the end upright similar to the profile 6 with masking function in the assembled state of said profiles. By similar profile is meant a profile having, seen in cross section, a shape similar or identical to that of the masking profile 6. Preferably, said shape is identical to that of the masking section 6 to limit the number of parts to be produced. This profile 13 similar to the masking profile 6 is therefore mounted by sliding interlocking on the profile 4 with grooves and is assembled to the profile 4 with grooves by cooperation of complementary geometric shapes as for the profile 6 masking with the profile 4 with grooves. The profile 12 which closes off the second longitudinal groove 11 of the grooved profile 4 can be called a finishing profile. According to a preferred embodiment, the finishing section 12 is fixed, preferably by means of a screw 7', by a branch of its U-shape, to a partition of the section 4, the fixing then being concealed by the retaining profile 13 (see Figure 6). Alternatively, the profile 12 can simply be held between the profile 4 and the profile 13, with a possible lateral play of the profile 12 which remains limited by the profile 4 and the profile 13 forming a stop.

In the examples shown, at least one, in this case each of the longitudinal grooves 9, 11 of the grooved profile 4 is delimited by an axial cavity 14 passing through the profile 4. This cavity 14 is, seen in cross section, of generally quadrangular shape and the opening of the groove is made in one of the open corners of said cavity 14. 100 and 101, one of which, shown at 101 in the figures, extends back from the section 6 with a masking function in the assembled state of said sections. Thus, the edge 101 of the opening 10 of the longitudinal groove 9 of the grooved profile 4 is set back from the profile 6 in the assembled state of the profiles. It should be noted that in the same way, the edge 151 of the opening 15 of the longitudinal groove 11 of the groove profile 4 is set back from the profile 13 for holding the profile 12 of the finish. This arrangement allows a variable angular positioning of the blade on the profile to which it is fixed as illustrated in FIG. 7. This FIG. 7 also illustrates the case where the same end upright 3 can receive two stacks of blades to form a line of panels, such as a fence. This end post 3 is common to two adjacent panels, said panels thus being assembled to one another by their end post. As illustrated schematically in Figure 7A, each stack of blades can, before its attachment to the upright 3 end, be engaged in the upright 3 end being oriented at an angle chosen in a given angular range. Thus, as shown in Figure 7A, it is possible to orient each stack of slats at an angle of between 0° (inclusive) and 45° (inclusive) with respect to the plane of symmetry of the end upright 3.

In practice, the manufacture and assembly of a panel 1 according to Figures 1 to 7 operates as follows. A first profile, generally the grooved profile 4 of each end upright 3 pre-equipped with a foot 16 or associated with a foot 16 is positioned in the upright state so that the grooved profiles 4 of the uprights d end have their first longitudinal groove 9 opposite one another. The blades 2 are then inserted into the longitudinal grooves 9 facing said profiles 4 with grooves so that these blades rest one on the other by their edge. Thus, the face of a blade serves to form one of the faces, for example the front face of the panel, while the opposite face of the blade serves to form the other face, for example the rear face of the panel. Each blade 2 is, at each of its ends, fixed to the grooved profile 4 by a connecting member 7. Once the assembly of the slats 2 has been completed, a section 6 for masking the connecting members 7 is attached to the level of each upright 3 at the end and coupled by sliding interlocking to said profile 4 with grooves of the said upright 3 at the end so that in the assembled state of the profiles of the upright 3 end, the connecting members 7 are hidden.

In the case of a panel according to Figure 8, again a first profile, generally the grooved profile 4 of each end upright pre-equipped with a foot 16 or associated with a foot 16 is positioned at the erected state so that the profiles 4 with grooves of the end uprights have their first longitudinal groove 9 opposite one another. A U-shaped section 5, provided with external longitudinal flanges on each branch, is fitted in one of the grooves of the profile 4 with grooves of each upright 3 at the end. The slats 2 are then inserted into the grooves facing said U-shaped sections 5 so that the slats rest one on the other by their edges. Each blade 2 is, at each of its ends, fixed to the U-shaped profile 5 by a connecting member 7. Once the assembly of the slats 2 has been completed, a profile 6 for masking the connecting members 7 is attached to the level of each end upright and coupled by sliding interlocking to the grooved profile 4 of the said end upright 3 so that the assembled state of the profiles of the end upright 3, the connecting members 7 are hidden and the profile 5 is kept assembled to at least one of the other profiles of the end upright 3 to avoid any disassembly of the profiles between them under the effect of a traction exerted on each of the sections in a direction transverse to the longitudinal axis of said section.
