Description

METHOD FOR MANUFACTURING A COVER HAVING A

EXTRUDED BODY AND A LOOP OF THE SAME APPEARANCE
The invention relates to the trim of the roofs of motor vehicles, and more specifically to a method of manufacturing a trim having an extruded body and a hatch of the same appearance.
The roofs of motor vehicles often have a longitudinal groove in which are provided devices for fixing the feet of luggage rack galleries or roof bars. These grooves are masked by bezel caps. These hubcaps have openings intended to let the feet of the galleries pass; the openings are closed by a hatch when the galleries are not used, so as to preserve the continuity of the vehicle roof.
The hubcaps are commonly produced from profiles obtained, depending on the material used, by profiling, extrusion or spinning. The profile is then shaped, if necessary, in order to be able to integrate into the roof of a vehicle. It also undergoes finishing operations such as cutting openings for fixing galleries or roof bars and cutting ends. Then, the profile must possibly be painted to meet the aesthetic criteria in force in the automotive industry. In this regard, it is desirable that the hubcap offer a homogeneous appearance. In particular, it is desirable that the body and the hatches of a hubcap provide the same appearance and this, in a lasting manner. It is also desirable to be able to obtain an ornament of the same color as the body of a motor vehicle, such as 'a metallic color.
Various types of motor vehicle roof trim are known with hatches, such as tilting, sliding or retractable hatches. In addition, solutions have been proposed for processes for manufacturing motor vehicle roof trim. For example, FR-A-2 811 623 and EP-A-1 132 242 teach methods of manufacturing a hubcap but do not describe obtaining a hatch and a hubcap body of the same appearance.
There is therefore a need for a method of manufacturing a hubcap, that is to say comprising a hatch and a body, of the same appearance and for hubcaps obtained by this method.
The subject of the invention is a method of manufacturing a hubcap having an extruded body and a hatch, comprising a step of extruding a profile and cutting the hatch in this extruded profile.
In preferred embodiments, the invention includes one or more of the following features: - the method of manufacturing a hubcap further comprises a step of extruding the hubcap body, using a different die from that used in the 'extrusion step of the profile; - The method of manufacturing a hubcap further includes a step of making the hubcap body from the extruded profile; - The method of manufacturing a hubcap further comprises a step of cutting an opening in the body of the extruded hubcap; the cutting of the opening is carried out in a place separate from the place where the cutting of the hatch is carried out; - the cover body is obtained by extrusion on a metal insert; - the cover body is obtained by extrusion on two main faces of a metal insert; - The method of manufacturing a hubcap further comprises a step of assembling the hatch with a hatch support; - The method of manufacturing a hubcap further comprises a step of overmolding the hatch with a hatch support; - The method of manufacturing a hubcap further comprises a step of assembling the hatch support with the body of the hubcap.
The invention also relates to an automobile roof trim capable of being obtained according to the invention.
In preferred embodiments, the invention comprises one or more of the following features: - the hatch support is a tilting hatch support; - the hatch support is a retractable hatch support; - the hatch support is a sliding hatch support; - the hatch support connects two elastically deformable tabs and slides in guide grooves of the hubcap body.
Other characteristics and advantages of the invention will appear on reading the following description of preferred embodiments of the invention, given by way of example and with reference to the accompanying drawings showing: - Figure lA, a view in perspective of an opening cut in an extruded hubcap body according to a first embodiment of the invention; - Figure 1B, a hatch cut from an extruded profile according to a first embodiment of the invention; Figure 2, a perspective view of an opening cut in a first place of an extruded cover body and a hatch cut in a second place of the body, according to a second embodiment of the invention; Figure 3 , a perspective view of an extruded hubcap body and a hatch cut out from the body, according to a third embodiment of the invention; Figure 4, a section along a plane perpendicular to the longitudinal direction of the body of a hubcap obtainable according to the invention. FIG. 5, an extruded hatch, capable of being obtained according to the invention and a hatch support, before assembly; FIG. 6, an embellishment body and a hatch which can be obtained according to the invention, the hatch being assembled with a hatch support, before assembly with the body; FIG. 7, a hatch and its support sliding in a hubcap body capable of being obtained according to the invention; Thus, the invention proposes a method of manufacturing a hubcap having an extruded body and a hatch, comprising a step extrusion of a profile and cutting of the hatch in this extruded profile.
The hatch and the embellishment body are obtained in the same way, that is to say by extrusion. This process guarantees the obtaining of the same surface condition and therefore of the same appearance for the hatch and the body, which presupposes the use of at least one same material in common for the hatch and the body during extrusion. It is for example possible, in the barrel of an extruder, to mix coloring agents with a softened material which is then forced through a die. We therefore obtain an identical color for the hatch and the body and this, durably, because the degradations likely to occur will have the same visual impact in both cases. In addition, such a process is suitable for reproducing the body color of a motor vehicle because it gives rise to a uniform color, unlike injection molding processes, for which the introduction of coloring agents generally results in uneven color dispersion and non-optimal physical properties of the final article. Apart from the colorings obtained by the introduction of coloring agents, it is also possible to apply a paint or any similar surface coating for the hatch and the body. The treatment applied to the hatch and to the hubcap body offers an identical appearance and this, durably, because, again, any degradations will have the same visual consequences for the hatch and for the hubcap body.
The manufacturing method, according to a first embodiment of the invention, of a hubcap having an extruded body and a hatch of the same appearance will now be described with reference to FIG. 1.
Figure 1 shows a perspective view of an opening cut in a body 11a of extruded cover (Figure 1A) and a hatch 20 cut in an extruded profile 11B (Figure 1B). In this first embodiment, two separate dies are used: one used for the extrusion of a body 11A of hubcap, the other used for the extrusion of a profile 11B to be used for the production of hatches . The body 11 of the hubcap is elongated and has two sides 13A, 14A and an outer surface (that is to say, the upper surface). The opening is cut in the body 11A of the hubcap. The profile 11B does not have to have the same characteristics as those of the cover body 11 A, in particular in the direction of the width of the profile 11. It is simply desirable for the profile 11B to at least partially reproduce the body curve 11A. In particular, the thicknesses of the body 11A and of the profile 11B can be different. The sides 13A, 14A of the body 11A can also be delimited by a flange 15A, 16A at one end, like the example shown in the figure, so as to form lateral guides 13A, 14A for sliding doors, as will be described with reference to FIGS. 6 and 7. The section of the flanks 13A, 14A can also be of curved shape and inclined with respect to a direction perpendicular to the mean plane of the upper surface (as will be described with reference to the figure 4).
The method of manufacturing a hubcap 10, in the first embodiment, comprises the steps: (a) extruding a body 11A of hubcap and cutting into the extruded body an opening; and (b) extruding a profile 11 and cutting from this profile 11 a hatch. The body and the profile are therefore obtained via two process steps, of any order, which preferably use two separate dies. Although they can also be of different shapes, the two channels can nevertheless have common dimensions, necessary for obtaining a hatch 20 whose profile is consistent with that of the opening cut out from the body 11A. cutting means, for example of die-punch type, are adapted so that the hatch 20 is insertable into the opening cut in the body 11A and, preferably, without notable discontinuities on the external surface of the profile (except for the residual separation space between the hatch 20 and the body 11 in the assembled position). Profile 11B serves as a base for cutting a plurality of hatches, its width is such that it allows a clean cut while minimizing the amount of unused material. We could for example mix coloring agents with a softened material in the sheath of an extruder and then force the softened material through two separate dies.
In the case where different dies are chosen, each of these dies can be optimized for obtaining the corresponding profile.
The advantages linked to the products resulting from this process are the following: the hatch 20 and the body 11A of the hubcap being obtained in similar ways, the same surface condition is obtained for the hatch 20 and the body 11A, which will therefore offer the same aspect. This presupposes the use of at least one and the same material in common for the hatch 20 and the body 11A during the extrusion steps. We therefore obtain an identical color for the hatch 20 and the body 1 lA and this, durably, given that any degradations will have the same visual impact in both cases. Such a process gives rise to a uniform color, unlike the processes injection molding machines, for which the introduction of coloring agents generally results in uneven color dispersion and suboptimal physical properties of the final article. Apart from the colorings obtained by the introduction of coloring agents, it is also possible to apply a paint or any surface coating, similar for the hatch 20 and the body 11A. The treatment applied to the hatch 20 and to the body 1 lA of hubcap offers the same appearance and this, durably, because, again, the potential degradations will have the same visual consequences for the hatch 20 and for the body 1 lA of hubcap.
The manufacturing method, according to a second embodiment of the invention, of a hubcap 10 will now be described with reference to FIG. 2.
FIG. 2 shows a perspective view of an opening cut at a first location from a body 11 of extruded hubcap and a hatch 20 cut at a second location of the body 11, according to a second embodiment of the invention. In this second embodiment, a single die is used for the extrusion of the body 11 of the hubcap. The body 11 has characteristics similar to those of the body 11 A of the first embodiment.
The method of manufacturing a hubcap 10, in this second embodiment, comprises the steps: (a) extruding a body 11 of the hubcap and cutting the body 11 extruded from an opening in a first location ; and (b) cutting a hatch 20 at a second location on the body 11. The body 11 is obtained in an extrusion step and has the advantage of using only one die. The hatch 20 and the opening are cut in two separate places. The body section 11 in which the hatch 20 is cut is itself separated (as indicated by two double arrows in the figure) from the rest of the body 11 for subsequent application (for example, recycling).
The advantages linked to the products resulting from this process are similar to those of the previous embodiment.
The manufacturing method according to a third embodiment of the invention of a hubcap 10 will now be described with reference to FIG. 3.
Figure 3 shows a perspective view of a hatch 20 cut from an extruded body 11. In this third embodiment, a single die is used to obtain the body 11. The body 11 has characteristics similar to those of the body described in the previous embodiment.
The method of manufacturing a hubcap 10, in this third embodiment, comprises a step of extruding a body 11 and a step of cutting into this body 11 extruded from an opening, the part resulting from the cutting being then used as a hatch. Again, the body 11 is obtained in an extrusion step which uses only one die. The hatch 20 and the opening are cut in one place of the body 11, without loss of material. The use of the material is therefore fully optimized in this embodiment.
The advantages linked to the products resulting from this process are similar to those of the previous embodiment but their cost price is necessarily lower.
It is possible, for example, and in each of the three preceding embodiments, to make the hubcap out of PVC, polypropylene or any thermoplastic material. The average thickness of the body 11 and the hatch 20 is preferably chosen between 1 mm and 3 mm. It is also possible to delimit the axial ends of the hubcap by cutting out the bodies 11 of extruded hubcap.
According to a variant of each of the three preceding embodiments, the method of manufacturing a hubcap 10, further comprises the production of docking lips. These lips can be produced along the body 11. These lips are made more flexible than the body 11 and the hatch 20 of the hubcap (by varying their thickness and / or their material, by co-extrusion and as known from l 'art) and allow to compensate for the clearances between the sides 13,14 of the body 11 of the hubcap and the sides of the roof groove with which the hubcap is to be assembled. When the hubcap is introduced into a groove, the lips press on the edges of the groove. Under the insertion force, the lips flex and fill the transverse play between the hubcap and the groove. The hubcap thus produced can be placed in a roof groove which is not perfectly straight, compensating for variations in width. .
A variant of each of the preceding embodiments will now be described with reference to FIG. 4.
Figure 4 shows a section along a plane perpendicular to the longitudinal direction of an exemplary body 11 of a hubcap 10 capable of being obtained according to the invention. The sides 13, 14 of the body 11 are delimited by a flange 15, 16 at one end, so as to form lateral guides 13, 14 for sliding doors, as will be described with reference to FIGS. 6 and 7. The section of the sides 13,14 is curved in shape and inclined with respect to a direction perpendicular to the mean plane of the upper surface. The body 11 comprises a metal insert, the contours of which are represented in the figure by a bold line. The insert is covered over most of its external surface (a main surface) with an extruded layer; it can also be covered with an extruded layer on part of its internal surface (i.e. another main surface). , like the example shown in the figure. The extruded part on top of the insert may also have docking lips.
Such a hubcap 10 is capable of being obtained by a manufacturing process comprising an extrusion on a metal insert. Thus, the body 11 is formed from a combination of at least two materials. The rigid metallic insert ensures the mechanical retention of the body 11 of the hubcap while the material extruded on the insert confers optical, touching and protective properties on the hubcap. The use of at least one common material for the extrusion of the hatch 20 and of the body 11 makes it possible to obtain the same surface condition and, consequently, the same appearance for the hatch 20 and the body 11. It is in particular possible to reproduce a homogeneous color, including a metallic color faithful to the color of the vehicle body. The common extrusion material may be PVC, polypropylene or any thermoplastic material. The average thickness of the body 11 (including the insert) and of the hatch 20 is preferably chosen between 1 mm and 3 mm and the average thickness of the insert is preferably between 0.5 and 1.5 mm. It is also possible to produce docking lips in a material different from that used for the extrusion of the rest of the body 11 of the hubcap, in particular when seeking different flexibility properties. The lips will in this case be produced by co-extrusion, as is known in the art. It should be added that the hatch 20 can be obtained by cutting from a profile independent of the body and also extruded on a rigid support such as a metal insert.
According to a variant, the hubcap is capable of being obtained by a manufacturing process comprising an extrusion on two main faces of a metal insert, such as the external surface and the internal surface, as in the example shown in the figure 4. In addition to the advantages mentioned above, extrusion on another face, for example the internal face, makes it possible to obtain a film. This is particularly advantageous when using a support 22 for the hatch sliding under the external surface of the hubcap and in the lateral guides 13,14 formed by the sides 13,14 of the hubcap. Indeed, the presence of the film makes it possible to protect the external surface of the hatch 20 against the flange formed by the metal insert and the insert itself, which would risk, otherwise, scratching the hatch.
FIG. 5 shows an extruded hatch 20, capable of being obtained according to the invention and a hatch support 22, before assembly. The hatch 20 and its support 22 can be assembled according to the double arrow shown in the figure, with fixing means such as an adhesive or latching means, as is known in the art. The support 22 will be described in more detail with reference to FIGS. 6 and 7.
In addition, the hatch 20 can be obtained by overmolding with its support 22, as is known in the art.
FIG. 6 shows a body 11 of the hubcap and a hatch 20 capable of being obtained according to the invention, the hatch 20 being assembled (or overmolded) with a support 22 for the hatch, before assembly with the body 11. Although this is not essential, the hatch 20 and its support 22 are pre-assembled (or overmolded) in this example. They can then be assembled to the body 11 of the hubcap according to the double arrow shown in the figure, using means known in the art. The support 22 is in this example a support 22 provided for sliding in lateral guides 13, 14 of the body 11 of the hubcap. The support 22 connects two elastically deformable legs 25, 26 which can be pressed laterally and then be housed in the lateral guides 13, 14 formed by the sides 13, 14 of the body 11 of the trim. The shape and the material chosen for the legs 25,26 also allow vertical deformation (in the vertical direction represented by the double arrow in the figure). FIG. 7 shows an example of hatch 20 and its support 22 sliding in a body 11 of hubcap capable of being obtained according to the invention. The support 22 is of the type described with reference to the previous figure. Typically, a simple pressure on the hatch 20 allows the hatch 20 and its support to be slightly depressed, as shown by an arrow in the figure. The legs 25, 26 are deformed, thus creating a return force of the hatch 20 and its support 22 upwards. Then, the hatch 20 and its support 22 can be slid under the body 11 of the hubcap, as shown by another arrow in the figure. A clip can be placed on the internal surface of the hubcap so as to stop the running stroke the hatch 20 and its support. A roof of a roof or a gallery can then be mounted in the cleared cavity after the sliding of the hatch. After use, a simple pull carried out by the user on a tab allows the hatch to be partially brought back. Then, the hatch 20 can be slid by the user to be brought back under the opening where the stroke of the hatch 20 and its support 22 is stopped by another clip. The restoring force exerted by the tabs 25, 26 automatically pushes the hatch 20 back into the closed position.
The benefits are manifold. In the closed position, the hatch 20 has the same appearance, seen from above, as the body 11 of the hubcap. The dimensions of the hatch 20 can be modeled on those of the opening cut in the body 11 of the hubcap, so as to offer an impression of continuity to the user. As, moreover, the hubcap can be assembled with the groove provided on the roof of the vehicle so as to be flush with the external surface of the roof, and its color can be chosen so as to reproduce the color of the vehicle body, the overall aspect is clearly improved.
Other types of supports can be used, as known in the art, and offer advantages similar to those mentioned above.
Of course, the present invention is not limited to the examples and embodiments described and shown, but it is susceptible of numerous variants accessible to those skilled in the art. In particular, these variants may relate to the production of attachment means at the axial ends of the body 11 of the hubcap. These attachment means may have two hooks extending along the length of the hubcap. It is thus possible to add a second intermediate cover 10 and fix it to the first. The second trim 10 can have complementary hooking means for the hooks, such as holes in which the hooks are fixed. We can then add a third hubcap 10, preferably identical to the first and fix it to this second hubcap 10.
