Description

METHOD FOR MANUFACTURING A WALL

The invention described below relates to the technical field of coffins. More precisely, the technical field of manufacturing coffins, in particular a coffin wall.

State of the art

Existing coffins are made from heavy materials, such as wood or wood-based materials. When the walls of the coffin, similar to those used in the furniture industry, are for example made of an MDF substrate covered with a decorative layer to give the panel a qualitative appearance, there is a risk that harmful substances, such as as the glue from the MDF substrate, are released into the environment when the coffin is buried or burned.

There are also coffins made of lighter materials, such as cardboard. However, these coffins often do not offer sufficient strength to be used during a funeral ceremony and lack quality finish and appearance. Such a coffin is also not very robust and risks being damaged.

It is necessary to have a lightweight and reliable coffin, which has a quality finish and appearance, is durable and environmentally friendly and is suitable for cremation and/or composting. There is also a need to manufacture such a coffin in a simple and efficient manner.

There is also a similar need for other applications of such improved walls to be easily and efficiently manufactured, e.g., lightweight, robust, durable and reliable. These walls can then be used, for example, as a box, box, panel, etc., particularly in applications where a reduction in weight and/or an increase in durability is sought.

Summary

According to a first aspect, we propose a process for manufacturing a wall comprising the following steps:
- provision of a base wall in the form of a plate made of a first material;
- application in the base wall of one or more grooves for the contour of the wall;
- filling the groove(s) by fixing one or more slats made of a second material to form the contour of the wall; And
- application of a coating layer at least on one side of the wall where the grooves have been applied.

We thus produce a light wall while maintaining sufficient strength. Applying the coating layer to the side where the grooves have been applied reinforces the whole, resulting in a lightweight and strong unit. Producing the contour in a material different from that of the plate-shaped base wall makes it possible to obtain a more qualitative appearance of the wall, in particular when the material of the plate-shaped base wall is covered and only the outline of the other material remains visible. We also obtain a more robust wall since the contour is typically the part most exposed to the risk of damage. Furthermore, it is possible to produce a lighter wall by using a lighter material for the base wall, for example, while the slats can still guarantee greater strength than the base wall, for example. Finally, this process offers an efficient and easy way to manufacture the wall. The grooves forming a sort of mold for the application of the slats, this operation can be carried out very easily and quickly. Fixing the slats can also be done very easily and quickly, for example by applying glue in the grooves before applying them. Furthermore, this process can be carried out using the same equipment already used for the manufacture of known walls, such as walls consisting of an entire plate made of a single material. It is also clear that the grooves can also be designated as notches, or as a furrow.

According to one embodiment, there is provided a method by which the covering layer is applied so as to cover and connect at least part of the slats and at least part of the first material.

detailed description

There schematically illustrates a first step of an embodiment of the wall manufacturing process. In the case of the embodiment illustrated in , for example, it is a wall for a coffin. However, it is clear that other embodiments are possible when any suitable wall is possible, such as, for example, a wall used for a box, a crate, a panel, etc., and where the wall must not not necessarily represent a fixed element in the whole. The wall may correspond to the lid of a box or another removable or mobile element of an assembly. There shows a top view of one embodiment of a base wall 20. According to this embodiment, the base wall is of rectangular dimension with a length L, for example between 1 m and 2.5 m, 2.2 m for example, and a width W of between 0.2 m and 1.5 m, 0.68 m for example. According to the embodiment presented, the base wall 20 is made of a first material, such as paper or cardboard. In the embodiment presented, the base wall 20 is for example made of a cellular cardboard panel. As shown in the , which presents the cross section along line II-II of the , such an embodiment of the base wall 20 consists of a composite cardboard panel, in which between an upper layer 22 and a lower layer 24, which consists of, for example, a cardboard plate, an intermediate layer 26 is applied which contains a certain structure, such as, for example, a hexagonal structure formed by means of cardboard walls, which extend transversely with respect to the upper layer 22 and the lower layer 24. Such a cardboard panel is known from the skilled person and is called, for example, a cellular panel. Such an embodiment of a base wall 20 made from a first material offers the advantage of a light base wall 20 while being more rigid and more resistant than an ordinary cardboard plate due to its stratified structure. The base wall 20 has for example a thickness T of 2 mm to 10 cm, for example 1 cm. It is therefore clear that the thickness T extends in a direction transverse to the plane determined by the longitudinal direction L and the direction in the width direction W of the base wall 20.

According to the exemplary embodiment presented, during a following step of the process, a groove 30 is milled in the base wall 20. As illustrated, this groove 30 is milled for the contour 14, that is to say the circumference of the wall 12 of the coffin. According to the exemplary embodiment presented, this wall 12 is, for example, an upper wall, a lower wall or a side wall of a coffin. However, it is clear that numerous variations in terms of shape of the contour 14 of the wall 12 are possible according to other embodiments. According to the example of embodiment presented, a single contiguous groove 30 is formed for the contour 14 of the wall 12, but it is understood that other embodiments are possible in which two or more separate and/or contiguous grooves 30 are applied, for example by a milling operation. As shown in the , which presents the cross section along line IV-IV of the , the groove 30 is applied in the base wall 20 such that it does not extend completely through the base wall 20. In other words, the depth of the groove is less than the thickness of the base wall 20, that is to say in the direction of the depth T.

As shown in the , according to the exemplary embodiment presented, during a following step of the process, the groove 30 is filled with slats 40, for example wooden slats 40. As can be seen in the , as well as on the cross section along line VI-VI of the , the section of the slats 40 corresponds, or almost, to the section of the groove 30. In other words, the dimensions of the slat in the directions transverse to the longitudinal direction of the groove 30 and the slat 40 correspond, or almost. In other words, the depth of the groove in the depth direction T corresponds, or almost, to the thickness of the slat 40 in this depth direction T. Likewise, the width of the groove 30 is that is to say parallel to the longitudinal plane of the wall 12 and transverse to the longitudinal direction of the groove 30, almost corresponds to the width of the slat 40 in the corresponding direction. In other words, the width of the groove 30 corresponds or almost to the width of the slat 40 applied in the groove 30. It is further obvious that, as shown in , the slats 40 have been applied in the groove 30 so as to together form the contour 14 of the wall 12 of the coffin. According to the exemplary embodiment presented, the contour 14 is formed by several contiguous slats 14 applied in the groove 30. However, it is understood that, according to other embodiments, any appropriate number of grooves 30 and/or slats 40 applied therein can be used to form the outline 14 of the wall 12 of the coffin.

The slats 40 which fill the groove 30 are for example fixed thereto by means of a suitable glue or other suitable fixing means, for example nails, screws, etc. As shown in , it is clear that the fixed slats 40 are configured to form the contour 14 of the wall 12 of the coffin. The slats 40, which, according to the embodiment presented, are wooden slats 40, therefore contain a second material, different from the first. It is clear that, according to this exemplary embodiment, the second material preferably has a tensile strength and a rigidity greater than those of the first material. In other words, the wooden slats 40 are stronger, more robust and more rigid than the cardboard honeycomb panel of the base wall 20. However, it is also clear that the first material, similar to this exemplary embodiment is preferably lighter, more quickly compostable, biodegradable and/or sustainably combustible than the second material. In other words, the cardboard honeycomb panel of the base wall 20 is lighter and faster to compost and biodegrade than the wood of the slats 40.

It is clear that many alternative embodiments are possible, other suitable materials being able to be chosen for the first material and the second material. Thus, as described above, the first material compared to the second has at least one of the following characteristics: lower weight, lower tensile strength, lower rigidity, better compostability, better biodegradability, better and/or faster combustibility. Thus, a coffin whose walls are made of these materials with low environmental impact can be optimally used in cemeteries, cremations, etc., and the reduced weight also allows better handling when transporting the coffin, as well as when of the funeral ceremony.

According to preferred embodiments, the first material comprises one of the following elements: paper or cardboard, such as, for example, corrugated cardboard, a cellular cardboard panel, any other cardboard panel. These materials are lightweight, have good composting and biodegradation capacity, as well as good and rapid combustibility. In addition, these materials can be produced in an environmentally friendly manner.

According to preferred embodiments, the second material contains at least one of the following materials: wood, composite wood, metal and/or plastic. The application of slats 40, such as wooden or metal slats, or slats of any other suitable material, makes it possible to obtain a contour 14 of the wall which has greater tensile strength, greater rigidity and a more robust and qualitative character. The slats 40 should be considered as any suitable elongated element, such as, for example, an elongated metal profile, a bar, etc.

As shown in the , during a following step of the embodiment of the method, after having fixed the slats 40 in the groove 30, the contour 14 of the wall 12 of the coffin is manufactured by edging the slats 40 applied in the grooves 30. As we can see, this demarcation of the slats 40 guarantees that they form the outer perimeter of the wall 12. According to the exemplary embodiment presented for example, the demarcation is carried out by a milling operation, where the milling cutter is guided so to follow a trajectory around the perimeter of the wall 12, milling through the entire thickness T of the base wall 12. In other words, as is visible, all the parts located outside the contour 14 of the wall 12 of the coffin are removed or separated from the wall 12 by this boundary.

As shown in the and the cross section along line VIII-VIII of the , in the illustrated embodiment, the width 42 of the slats 40 applied in the grooves 30 is reduced during demarcation. In other words, according to the direction of the plane of the wall 12, and perpendicular to the longitudinal direction of the slat 40, the width 42 of the slat 40 after the demarcation is smaller than before the demarcation, as shown in . In other words, this means that during demarcation, for example by milling, part of the slat 40 is removed by milling to form the contour 14 of the wall 12. It is understood that other embodiments are possible, where , for example, during demarcation, the width 42 of the slat 40 is not or practically not modified and the contour 14 of the wall 12 is formed by the face facing outwards of the slat 40.

It is understood that other embodiments are still possible, preferably by manufacturing the contour 14 of the wall 12 of the coffin by edging the slats 40 applied in the grooves 30 so that the slats 40 form the exterior contour of the wall 12. However, according to an alternative embodiment, it is also possible to provide the edge of the contour 14 of the base wall 20 before the application of the slats 40, in particular in the case of an embodiment where the slats 40 do not need to be lined further. This means that during or after the application of the grooves in the base wall, the contour 14 of the wall 12 is also bordered in the base wall 20, so that for example a base wall with grooves 30 is produced. and a bordered contour 14 in which the slats 40 can then be applied.

It is understood that, according to the embodiment described above, the grooves 30 for the contour 14 of the wall 12 of the coffin which are applied in the base wall 20 by means of a milling operation, according to modes of alternative embodiments, can also be applied in the base wall 20 by other suitable operations, such as, for example, a sawing operation, a planing operation, a cutting operation, etc., where the grooves 30, which can also be called notches, cuts, incisions, etc., are formed in such a way that the slats 40 can be applied thereto, or in other words, in which the grooves do not extend completely through the material of the base wall 20 so that the applied slats can be supported and fixed on the bottom of the groove 30. In doing so, it is clear that this operation makes it possible to apply the groove(s) 30 in the base wall 20 across, depending on the orientation of the , the upper side 16 of the base wall 20.

It is also obvious that, according to alternative embodiments, in addition to the milling operation described for delimiting the contour 14, for example by edging the base wall 20 and/or the slats 40 applied in the grooves 30, according to alternative embodiments, other suitable claims are also possible for demarcation, such as, for example, a sawing operation, a planing operation, a cutting operation... where, preferably, the contour 14 of the wall 12 of the coffin is manufactured by edging the wall 12 along a trajectory surrounding the contour 14 of the wall 12 and completely crossing the base wall 20.

In doing so, it is clear that, as the , according to the embodiment shown, after the demarcation, the slats 14 become visible on the side of the wall 12 forming the contour 14 of the wall. This gives a robust and qualitative character to the contour 14.

The illustrated embodiment of the wall 12 in Figures 1 to 8 could be, for example, an upper wall 12 of a coffin, where it is sufficient to manufacture only the contour 14 by means of slats 40 made of a second material. According to the alternative embodiment of a wall 12, shown in , in addition to the grooves 30 for the contour 14 of the wall 12, the grooves 50 for the reinforcing ribs 18 of the wall 12 are also milled into the base wall and filled with slats made of a second material, such as for example wood , metal or other suitable material. Similar items are shown in by similar references to those of the embodiments described above and operate in the same manner. The state of wall 12 illustrated in corresponds to that of the , that is to say after the contour 14 of the wall 12 has been bordered. In other words, the embodiment of the wall 12 illustrated in was manufactured in a manner similar to that described above, by providing a base wall 20 in the form of a plate in which grooves 30 for the contour 14 of the wall 12 were then applied, which were then filled in fixing slats 40 in this groove 30 to form the contour 14, and finally by manufacturing the contour 14 by edging these slats 40 so that these slats 40 form the outer perimeter of the wall 12. In addition, according to this method of manufacturing the wall 12, additional grooves have been applied for the reinforcing ribs 18. The wall 12 illustrated represents for example a side wall of a coffin. It is however obvious that such an embodiment is advantageous for the manufacture of any other wall of the coffin subjected to a greater load, such as for example due to the weight of the deceased contained in the coffin, such as for example the bottom wall , the side wall, the front wall, the rear wall, etc. According to this embodiment, such a wall is manufactured by means of additional steps of milling grooves 50 for the reinforcing ribs 18 in the wall 12 of the coffin 10 in the base wall 20. During the next step, these grooves 50 are then filled by fixing one or more slats 40 made of a second material to form the reinforcing ribs 18 of the wall 12 from the coffin. As described above, an adhesive may be applied in the grooves 30, 50 and/or on the slats 40, preferably before the slats 40 are applied in the grooves 30, 50. However, it is obvious that the slats can also be attached to the groove and/or neighboring slats 40 by means of additional and/or replacement fasteners. It is also understood that the number, location and/or shape of the grooves 50 for the reinforcing ribs 18 may vary from the embodiment shown.

There illustrates an embodiment of the method described above, by which several walls 12 are manufactured from the same base wall 20. According to the exemplary embodiment presented, these are two walls 12 similar to those of the and like items are indicated by like reference numerals and operate similarly. There shows the step of the process where the grooves 30, 50 for the two walls 12 are already applied in the base wall 20, before the slats 40 are fixed in the grooves 30, 50. According to such an embodiment of the process , as illustrated, a common groove 30 is applied in the base wall 20. In doing so, it is clear that this common groove 30 will be applied on a side close to the contour 14 for the two walls 12. In other words, from side where the two walls 12 are close to each other in the base wall 20. Obviously, in this common groove 30, a common slat 40 can be applied and fixed in the same way as the other slats 40 fixed in the grooves 30, 50 as described above. Then, according to the embodiment of this method, the side close to the contour 14 of the two walls 12 will be formed by dividing the common slat 40 in two and the common groove 30, as indicated schematically by the dotted line in the .

There shows the embodiment of the wall 12, as described above using Figures 1 to 8, during a following step of an embodiment of the described method of manufacturing the wall 12. According to this embodiment of the method, after the step described using the , that is to say after the application of the slats 40 in the grooves 30, 50, a coating layer 60 is applied. As indicated, according to the exemplary embodiment presented, the coating layer 60 is applied at least on the side 16 of the wall 12 in which the grooves 30, 50 have been applied. It should be noted that according to such an advantageous embodiment, the coating layer 60 on the side of the wall 12 in which the grooves 30, 50 are applied is configured to increase the resistance and/or the rigidity of the wall 12 in the state illustrated, for example, in with respect to the strength and/or rigidity in the state in which the grooves 30, 50 have been applied in the first material of the base wall 20 as illustrated, for example, in Figures 3 - 8. According to the example of embodiment presented, where the first material of the base wall 20 is, for example, a honeycomb panel, it is clear that in this way, the covering layer 60 connects the upper layer 22 of the honeycomb panel to the upper part of the slat 40. This again completes the sandwich structure, where, according to the exemplary embodiment presented, the slat 40, similar to the intermediate layer 26 of the cellular panel, is applied between two layers, namely the lower layer 24 of the cellular panel of the base wall 20, and the covering layer 60 which is connected to the upper layer 22 of the cellular panel of the base wall 20, thus forming, so to speak, an extension of the upper layer 22 connected to the slat 40. In this way, the upper layer of the sandwich structure of the wall, beyond the interruption of the grooves 40, is thus restored, which makes it possible to increase the resistance and rigidity of the wall 12 in its together. It then appears clearly that the orientation illustrated and discussed above can be modified, for example when the grooves are applied, as desired, along a visible or non-visible side of the wall 12, or when the wall is oriented so that the aforementioned top side faces down, sideways... or in any other suitable orientation.

It is then clear that the coating layer must not completely cover the side 16 of the wall 12. It is sufficient, as shown in the example of embodiment of the , that the coating layer 60 is applied so as to cover and connect at least part of the slats 40 and at least part of the first material of the base wall 12. It is thus clearly seen that the side wall of the groove 30 adjacent to the first material of the base wall 12 is covered by this covering layer 60, or according to the example of embodiment presented, that the side wall of the groove 30 adjacent to the intermediate layer 26 of the cellular panel is covered by the layer coating 60. As already indicated above, the coating layer 60 thus ensures the reinforcement of the rigidity of the panel 12 by the application of the coating layer 60, in particular at the level of the groove 30.

This covering layer 60 may comprise any suitable layer of appropriate rigidity. The coating layer 60 preferably comprises a finishing layer, for example a finishing layer 60 formed of a veneer, a finishing layer or finishing layers which include an imprint or pattern imitating a desired material, such as, for example, wood, stone, textile, .... or any other appropriate visual representation. According to the exemplary embodiment presented, only one side of the wall 12 is provided with such a coating layer 60. However, it is understood that, according to other embodiments, the opposite side as well as, for example, the contour of the wall 12 can also be provided with such a coating layer 60.

According to another embodiment, it is also possible to apply a coating layer 60 on the side which faces the side 16 in which the grooves 30 are located. Such an embodiment is for example illustrated in , where a coating layer 60 has also been applied to the underside.

According to another method of manufacturing the wall illustrated in , which has a cross section similar to that of the , after applying the slats 40 in the grooves 30, a coating layer 60 can be applied to the side 16 of the wall 12 in which the grooves 30 are applied. In other words, unlike the embodiment described above, the coating layer 60 is applied first, and only then is the contour 14 made by edging the slats 40, similar as illustrated in . It is obvious that, in the same way as for Figures 7 and 8, the width 42 of the slats 40 is reduced during the demarcation according to the exemplary embodiment presented. It is also clear that, according to the example of implementation presented in the , this demarcation is carried out when the covering layer 60 has already been applied.

Figures 16 to 19 show a top view of an alternative embodiment of a wall 12 manufactured according to an embodiment of a process similar to that described above. Thus, the four states illustrated in Figures 16 to 19 are similar to the states illustrated respectively in Figures 1 to 8. According to the embodiment presented, the base wall 12, as illustrated in , is also a cellular panel, for example containing cardboard or made of cardboard. Then, as described above, grooves 30 are applied in the base wall 20 for the application of the slats 40, as illustrated in , after which the contour 14 is made by edging the slats 40. In doing so, it is clear that the grooves and slats only have to approach the final contour of the wall 12, by means of the hexagonal shape presented , which, when edged, gives the final circular outline shown in .

It is clear that according to the method described above for the manufacture of a wall 12 for a coffin, a wall 12 is manufactured in which the contour 14 of the wall 12 of the coffin 10 is formed by the slats 40 made of the second material fixed in one or more grooves 30 of the base wall 20 made of the first material. According to one embodiment, it is possible to manufacture a coffin containing at least one such wall 12. This efficiently manufactured wall will thus reduce the weight of the coffin. The coffin 10 preferably comprises several of these walls 12, for example an upper wall as illustrated in Figures 1 to 8, side walls as illustrated in or 10... The slats 40, such as the wooden slats, which form the contour 14 of the wall 12 are also interesting for cooperating with the fixing elements of the wall 12 of the coffin. Thus, these walls 12 can be connected in a simple and robust manner to form the coffin.

Although embodiments of a coffin wall have been described above, it is clear that such a wall as well as the method of manufacturing such a wall can prove advantageous. According to other embodiments, these walls can be used, for example, as a box, crate, panel, etc. or any other suitable assembly comprising one or more of these walls, in particular in applications where a reduction in weight and /or an increase in durability is desired. According to certain embodiments, this assembly 10 may comprise or consist, for example, of a crate or box for shipping goods, a furniture panel, a wall panel, a ceiling panel, an acoustic panel, a panel advertising, etc. As described above, in such assemblies, one or more fixing elements for a wall 12 of the assembly 10 can cooperate with the slats 40 made of the second material forming the contour 14 of the wall 12.

It is further evident that other embodiments and/or combinations of the embodiments described above are possible without departing from the scope of protection as determined by the claims.
