Abstract

The invention relates to a method for obtaining a flexible material formed by at least two laminar layers of wood veneer glued together and connected to an elastic layer of rubber or the like. According to the invention, a series of cuts or slits is made in the wood-veneer cover laminar layer, the edges thereof being separated from one another by smaller and larger distances. The aforementioned cuts are oriented in different directions and have variable depths, without extending through the entire thickness of the wood layer. Moreover, said cuts define areas of wood veneer capable of flexing individually through movement of the material or friction with the body. The second wood-veneer laminar layer can be provided with cuts in the face opposite that which joins to the cover layer, thereby enhancing the flexibility thereof, or, alternatively, can be cut-free, thereby increasing the strength thereof.

Description

Procedure for obtaining a material flexible.

Technical scope

The invention relates to a method for obtain a flexible material that constituted with layers of sheets of wood on an elastic rubber base can be destined to upholster, line, cover or cover objects, despite being conformed with a material that individually is not very flexible but which together with the proposed procedure produces an increase in The flexibility of the material. In addition to arranging the material obtained on its face view a sheet of laminated wood allows be applied to various items that may be in contact direct with parts of the human body, without causing irritation or skin excoriations. Such material is obtained with the maximum flexibility so that it can be used satisfactorily as upholstery to cover or line domestic seats and / or seats for automobiles, or also as rest covers adaptable to said seats, as well as can be used for shaping floor and wall coverings or coverings, carpets and also as raw material for the manufacture of templates, soles for footwear and orthopedic material.

Background of the invention

In the current state of the art the existence of the invention patent number P0239225 is already known, which consists of a " Procedure for obtaining and manufacturing flexible pieces of wood adaptable by adhesion ", which protects the option of obtaining sheets or films of Thick wood that conveniently treated with chemicals, such as hydrogen peroxide, vitriol, nitric acid, etc., softens the wood to give it more flexibility.

These wood sheets or films are submitted by their faces to the impregnation of an adhesive for later by roller pair pressure can be attached to a tissue base, paper or plastic, intended to cover the walls as if they were wood panels.

It is also known the existence of the invention patent No. P0355486 for " Improvements introduced in the manufacturing processes of flexible boards based on plastic and woven wood " where a manufacturing procedure is followed very similar to that of the previous patent but which is carried out at certain temperatures and at very specific adhesion pressures.

The material obtained with these procedures patents is intended to be coupled to surfaces or walls flat where it is rigid as a decorative board and so both do not require, nor have enough flexibility for the material can bend without cracking, especially when intends to adapt to forms of certain structures that present curves, rounded or protruding areas and angular recesses.

Finally, it is worth highlighting the existence of the invention patent number 201030284 for " Multilayer element " whose holders are the same as those of the present application, and where the configuration of a multilayer element whose exposed face is constituted by a series of small pieces of wood or veneered wood and treated with variable contours with rounded edges and vertices that are arranged separately on a second layer in the form of flexible rubber sheet which favors the mobility of the pieces of wood, which form a series of ventilation channels of the body areas in contact or friction with said layer of
cover.

The multilayer element to get more resistance and flexibility is annexing more layers constituted by rubber pieces of different resistance to deformation and arranged on another layer of rubber to finish on a base of wear resistant studs.

This type of element presents very good flexibility results but it is more complex in its manufacturing as it consists of layers of small pieces that are they must mount and adhere to the flexible sheets to get the proposed result.

On the other hand it is also known by the state of the technique aimed at the footwear industry, the existence of soles for footwear that are made of wood, which It is very beneficial for the feet. Notwithstanding this kind of sole has the disadvantage that it is not flexible since it gets in the form of a wooden full body, so it turns out also very heavy and not very breathable, causing an excess of sweat on the feet

From what follows that these solutions known present problems with regard to flexibility of the material and therefore its application is more restricted in the market for its fragility.

Object of the invention

The present invention aims to overcome these inconveniences and bring to the market a procedure to obtain a more flexible wood material without losing its strength than improvement to existing materials in the market and that gives as result a material that can be adapted or adjusted to any irregular shape of different objects, without risk of occurrence breaks or cracks in the surface of the material.

It also allows to obtain other advantages additional derived from the fact that the material obtained uses natural components in its conformation, which favors the rubbing or material contact with the human body producing well-being, a certain massage and warmth to the touch.

And all this is obtained with a process of cuts special on the surfaces of wood veneers, which is of Easy and economical realization, which lowers the costs of manufacture of the material and that through its realization allows the manufacturer balance the strength and flexibility of the material so that there are no breaks in it, in accordance with the application to which it will be intended.

Description of the invention

According to the invention, the flexible material a obtain consists of at least two sheet metal layers of wood of the same or different thickness, which are glued together and attached to a third elastic layer of rubber, sponge or similar.

To increase the flexibility of the material, proceeds to make cuts or crevices in the laminar layer of wood veneer deck, which can be shaped with their edges more or less separated from each other, according to the tools cutting used.

The cuts are made on the surface of the cover layer in different directions and with a depth variable and limited since it must not get through the bulk of The wood veneer.

The cuts made delimit between them some areas of individual bending trained wood veneer when produces a movement of the material, especially when there is a pressure or friction with a part of the user's body.

The second sheet layer of wood veneer, free of cuts allowing use thinner sheets maintaining the adequate strength of the flexible material obtained.

Another option of the procedure to obtain a flexible material is to use a second sheet layer of sheet metal wood of the same thickness as the cover plate and make cuts or indentations on the opposite side of the joint with the layer cover sheet also provided with cuts on its face view.

The cuts or crevices made will have their roughly separated edges according to the tool used and they will be done following different directions and with a variable and limited depth without crossing the thickness of the Second layer of wood veneer.

These cuts made in the second layer Laminar can be performed in vertical coincidence and / or also displaced from the cuts of the cover sheet and therefore the delimited areas between the flexed cuts individually, they will be vertically centered and / or offset by below the flexor zones of the cover sheet.

When the cuts of the cover sheet made of wood veneer match the cuts of the second layer veneer sheet and therefore the areas are centered flexible on the same vertical axis, the material achieved is more flexible than when the cuts don't match, but it's also more vulnerable to breakage.

On the contrary when the cuts made in the veneer layers do not coincide in prolongation vertical and flexible areas of each layer are displaced some with respect to others, the material loses flexibility but gains in Breaking strength.

Therefore a balance can be achieved so that in both laminar layers certain cuts and others coincide are displaced in order to achieve flexibility and adequate strength of the material according to the application to which It is going to go.

The invention has also provided that when the material conforms to the union of more than two layered layers of wood veneer should proceed to make cuts or crevices in alternate layers of wood veneer, leaving an intermediate layer of wood veneer free of cuts between two layered layers with slits

These cuts will also be made with different directions and with a variable and limited depth and they will conform and start in the first cover sheet, to continue in the third layer of wood veneer and leaving the second laminar layer without cuts. If there were more layers, they would alternate the layers without cuts with the layers with cuts. Said cuts may or may not match those of a layer with the of the other alternating layers to keep the balance between flexibility and resistance to breakage of the material.

Finally, the set of layers that make up the material have strategic points of a series of perforations in vertical coincidence that they cross all the layers constituting aeration steps of the material while producing greater flexibility in the material.

For more understanding of it so far exposed is accompanied by the descriptive memory a set of drawings in which shows the object of the invention, without having to understood that the graphic representation referred to constitutes a limitation of the peculiar characteristics of this application.

Figure 1.- Represents a perspective view and flexible material section consisting of a sheet of covered with a combination of different cuts or grooves of edges very close together and others more separated, which remain different directions and whose depth does not reach through the sheet. By under the cover layer there is a connection arrangement second layer of wood of smaller thickness and below it an elastic layer of rubber, foam or the like is located. All layers are crossed by vertical perforations in coincidence or aeration holes.

Some cuts of the first laminar layer match the cuts of the second layer laminar and others are displaced. Below the second layer a third elastic layer of rubber, foam or Similary.

Figure 3.- Illustrates a perspective view and section of a third embodiment of the constituted flexible material by three laminated layers of wood veneer of which the layer first cover and third layer are provided with cuts or slits of the same characteristics as in the previous figures, while the second layer of wood or intermediate layer It is exempt from cuts. Below the third layer is located a fourth elastic layer of rubber, foam or the like.

Preferred Embodiment of the Invention

The following are listed and enumerated different elements that make up the preferred embodiment of the procedure for obtaining a flexible material.

Looking at the first figure you can see without difficulty that the flexible material is obtained from at minus two layered layers (1) and (2) of different veneer thickness, which will be glued together and attached to a third elastic layer (3) of rubber, sponge or the like.

The two layered layers (1) and (2) of sheet metal wood is conventionally joined by adhesives, providing cover sheet with the wood grain (1 ') transverse to its surface or face view, while the wood veneer of the second laminar layer is arranged with the wood grain (2 ') in longitudinal arrangement to its surface and therefore in the direction orthogonal to the vein of the first layer.

When more than two wood veneers are used to form the flexible material the wood grain is arranged (1 ') of the transverse cover sheet layer and the rest of the lower laminated layers of wood veneer present its vein (2 ') longitudinally.

To increase the flexibility of the material has been planned to make cuts or grooves (4) in the laminar layer (1) roof, whose wood veneer has a thickness about 5 mm.

The use of different tools of cutting like blades, strawberries, dies, etc., allows to vary the separation of the edges (5) or lips of the cut made on the surface (6) of the cover sheet. This has been possible check that obtaining a greater separation of the edges of the cutting achieves greater flexibility in the material than what It is achieved with cuts with the edges closer together.

It has also been proven that in any direction (7) that the cuts are made on the surface (6) of the sheet layer (1), the flexibility of the material is increased, being the depth (8) of the variable but limited cut because it cannot get through the thickness of the veneer of the layer laminate.

The cuts made delimit between them some wood veneer areas (9) that can be folded individually with material movement, especially when pressure occurs or friction with a part of the human body.

In the second sheet layer (2) of sheet metal wood is planned not to make any cuts to grant adequate resistance to the whole material without the need for use thicker sheets. In practice the use is valid of a sheet of 1 mm wood veneer. thick

The second figure shows that the material flexible is obtained with a second sheet layer (2) of sheet metal wood of the same thickness as the cover layer (1) and in whose laminar layer (2) on the opposite side (10) to that of union with the layer cover sheet, cuts or grooves are made (11).

The shaped cuts or slits (11) will have its edges (12) more or less separated, depending on the tool used, and will be done following different directions (13) and with a variable and limited depth (14) without crossing the thickness of the second laminar layer (2) of wood veneer.

These cuts (11) made in the second layer Laminate (2) of wood veneer can be made in coincidence vertical and / or also displaced from the cuts (4) of the layer cover sheet (1) and therefore flexible areas (15) of the laminar layer (2) delimited between the cuts (11), will remain vertically centered and / or offset below the zones (9) flexible cover sheet (1).

When the cuts (4) of the laminar layer (1) of cover match the cuts (11) of the second laminar layer (2) and therefore remain centered on the same axis or vertical plane the flexible zones (9) and (15) of the sheet layers, the material achieved has greater flexibility than when the cuts do not coincide, but is also more vulnerable to breakage.

On the contrary when the cuts (4) and (11) of the laminar layers (1) and (2) do not coincide in vertical extension and the flexible zones (9) and (15) of each layer are displaced some with respect to others, the material loses some flexibility but wins in resistance to breakage.

Therefore, if the layers (1) and (2) are they make a combination of cuts that match those of the upper laminar layer (1), with those of the lower laminar layer (2) and other mismatches and therefore shifted those of a layer with respect to the other, you can control flexibility and adequate strength in the material for the application to which It will go.

In the third figure it can be seen that the flexible material conforms to the union of three layered layers (1), (2) and (16) of wood veneer and proceed to make the cuts or indentations (4) and (11) respectively in the layers alternate laminar (1) and (16), leaving the laminar layer (2) intermediate free of cuts. These cuts will also be made with different directions (7) and (13) and with a depth (8) and (14) variable and limited, without crossing the respective layers of wood veneer

If more layers of wood veneer will be used to obtain the flexible material the layers would alternate Layers without cuts or crevices with the layers with cuts, the which can match the cuts of a layer with the cuts of the other layer to keep the balance between flexibility and resistance to material breakage.

In the first, second and third figure, observe in strategic points of the material the existence of perforations (17) that cross all layers constituting aeration steps of the material, which also improve flexibility of the same.
