Definitions
- the present invention concerns the technical sector relating to the production and installation of surfaces made of wood or other similar material, used for making floors, tilings, platforms or the like, mainly outside or in wet environments.
- this invention concerns the technical sector relating to the production of constructing elements necessary to set up a floor or tiling as above mentioned. Together with the construction of said elements, a series of accessories must be provided as well, in order to allow a perfect installation of the single constructing elements.
- the system and the device object of this invention aim at constructing said accessories as well as wood surfaces made of a series of said constructing elements.
- wood surfaces for civil or industrial purposes are realized by assembling the various elements forming the surface, without any intersection between each other, according to the so-called "open joint" system.
- These wooden elements, worked to form the surfaces are placed one close to the other at a prefixed distance, without creating any connection between them; in any case, even when these elements are connected in some way each other, open joints are always used, leaving gaps between the boards.
- This constructing system is particularly used for wood surfaces, since the wood is a material that is subject per se to size alterations due to temperature changes.
- the gap between the boards allows the wood to freely dilate, following the moisture produced by the atmospheric agents, without causing pressures and distortions to the wooden boards connected by it. Similarly, when the wood contracts due to dryness, this reversed movement of the boards does not alter the structure.
- the gap between the boards (the so-called open joint) will increase or decrease, but the structure of the surface will not be deformed at all.
- this system known at present has many drawbacks.
- the gap between the elements does not ensure the uniformity of the surface, involving serious effects also from a hygienic point of view. Inside this gap, dust, rubbish and bugs can enter, so preventing the use of the same surface.
- the present invention principally aims at avoiding these and other drawbacks, supplying a closed joint system for boards in wood or other similar material, subject to an expansion or contraction effect, which fits the joint into the board, making it steady and hardly visible from the outside.
- the present invention provides the possibility to apply a closed joint to the wood surfaces, so as to get the complete connection between the boards, without gaps. This closed joint prevents the access of dust and rubbish, so avoiding the effects of environmental degradation above cited. Despite these advantages, a closed joint, being rigid, could not be used anyway, because the wood surfaces placed outside would suffer from the effects produced by the moisture, causing in their turn the deformation of the overall system.
- This invention aims at realizing a closed joint that avoids the above-mentioned hygienic drawbacks and additionally cushions any effect of the increase in volume of the same wood, both in radial and longitudinal direction, in the presence of moisture or heavy rain, so preventing the deformation of the wood surfaces, with the result to keep the original stability and uniformity of the same surface.
- This can be reached, according to the present invention, by the application of a closed joint between the boards, made of any elastic material (rubber, caoutchouc, silicon, plastic) , as long as the boards used, which can take any geometrical shape according to their thickness and wideness.
- This joint has a central hole that makes it empty inside, for the entire length, so as to give it the flexibility necessary to cushion the natural expansion of the wood.
- Said joint can be alternatively filled with foam rubber or other soft and flexible material, suitable to prevent the access of bugs or other external agents inside the hole and at the same time capable of ensuring flexibility to the joint.
- the boards forming the surfaces are specifically made to get the notches where the elastic joint must be fitted, both at the top and on the sides. These notches have the same geometrical shape as the joint, with a positive tolerance in order to permit a better deformation of the joint, so as to absorb by less resistance the expansion of the wood.
- the joint thanks to its elastic feature, follows and completes the same movement.
- the wood surface should be made of season wood, of any essence, with a relative moisture not over 12-13%.
- a closed elastic joint offers the advantage to realize perfect hygienic wood surfaces, since the closure made by the joint between the boards prevents the access of dust and rubbish, as well as the advantage to avoid the deformation of the surfaces due to moisture, since the flexibility of the joint cushions and absorbs the natural expansion of the wood. Therefore, it's possible to set up these wood surfaces outside or in particularly wet environments, for any civil or industrial use, either private or public.
- a closed joint system for surfaces made of wood, or other similar material subject to temperature alterations constituted by a series of wooden boards applied one next to the other, according to the present invention, comprises : means to cover the gap between two or more boards, by an elastic joint of cylindrical or polihedric shape; - means to apply said joint to said boards, by a notch (4, 4A), on at least one side edge (7) of the boards (2), where the joint fits even only partially.
- the shape of said notches (4, 4A) corresponds almost to the longitudinal half of the joint.
- Said notch is preferably located over all the side surfaces of the board.
- half the joint lays on a side edge (7) that comprises a notch of corresponding shape.
- the joint has a cylindrical shape, consequently a circular section (1) , its notch (4) will be a semi-circle.
- the joint has an octagonal shape (IA)
- its notch (4A) will have a corresponding shape, suitable to hold the three side surfaces of the joint. And so on for all the other shapes the joint can take.
- the joint is slightly thinner than the board, so that it can be comprised between two boards and not visible, even during pressure.
- the joint has the same thickness as the board, every time the board expands, and the joint is pressed, a portion of the joint will go out from the board with consequent aesthetic drawbacks.
- the thickness is minor allows to support also this pressure, preventing the exit of the joint from the boards.
- the notch (4, 4A) where the joint fits is located in the central portion of the edge (7), so that at the top (8) and on the bottom (9) two light projections extend to keep the surface uniform at the top and on the bottom.
- the joint and the side edge of the board are complementary each other, so that, once the board is positioned, the joint perfectly enters a notch on the edge of corresponding shape. Which allows also to avoid possible gaps where the dust or other external agents can enter.
- These notches have the same geometrical shape as the joint, with a positive tolerance in order to permit a better deformation of the joint, so as to absorb by less resistance the expansion of the wood.
- This invention also includes the wood surface realized by this system, made by a series of boards placed one next to the other and connected by means of said elastic joint.
- This joint can be placed between each board and the next one or just between some rows according to the specific constructing needs.
- Said joint is made of any elastic material, such as rubber, caoutchouc, silicon, plastic.
- the external portion of the joint has self-extinguishing features, is resistant to UGV rays, frost, acids, is smooth and not porous, so as to be washed and cleaned out with powders or liquids .
- Said joint can take any shape and section. In particular, it can either be realized of indefinite or definite length, e.g. corresponding to the length of one or more boards .
- the length of the joint is not important at all for the realization of the invention at issue. However, it has preferably a length corresponding to the length of each board (2) forming the wood surface.
- the thickness of the joint is proportional to the thickness of the board (2), so that it cannot be seen once set up or go out from its place.
- the shape of the section of the joint is not important.
- the joint (1) has a circular section (Fig.
- Said joint (1) is hollow inside (3) for a greater flexibility; as a matter of fact, this characteristic allows the joint to contract and expand more quickly and easily.
- said joint (1) includes inside foam rubber or other similar material that permits anyway the joint to contract and expand, pressed by the stress on the board (2) , but at the same time prevents the access of bugs, dirt or other external agents inside.
- the joint instead of being hollow or filled with foam rubber or the like, can be entirely full inside with the same material it is externally made of. In this case the pressure will be slower, but the invention still permits to get the desired result.
- the joint has an octagonal section (IA), so that three of its side surfaces lay on the board, three on the opposite board, the remaining two, one at the top and the other on the bottom, fill the gap between each board.
- the joint can be filled inside with the same material of the external part, with foam rubber or the like, or can be hollow.
- the joint can also have different sections, e.g. hexagonal, oval or other.
- the joint is applied on all the side edges of the board. If a board (2) has a rectangular shape, said joint will be applied both on the two longer sides and on the two shorter sides, laterally to the same board.
- the joint can be applied between each board with no need of any further work.
- the joint in this solution, could have a square or rectangular section, so as to perfectly adhere to the edges of the boards it connects, but also any other shape permits still to get the desired result.
- the joint is simply applied between each boa'rd and preferably between a board and the next one, so that the entire surface is made of a series of wooden boards (2) connected each other by means of said joints. Yet, in order to better ensure the hold and stability of the joint, it is preferably stuck to the boards. .
- each board has on its side edge a portion equipped with glue, adhesive strip or the like, where the joint sticks. Said portion is located in the notch (4, 4A) where the joint fits.
- each joint has on its side a portion equipped with glue or adhesive means that sticks on the side edge (7), or inside the notch (4, 4A) where the same joint fits.
- FIG. 1 shows a closed elastic joint (1) of circular shape in radial section, with a central hole (3) that makes it hollow inside.
- This internal hole (3) can be filled with foam rubber.
- the circular section of the joint has a diameter of about 12 mm.
- This figure also shows a board of floor (2) with two notches (4) at the ends on its side edges (7) that hold the joint (1) and have a semi-circle shape. Said notches (4) have an upper (8) and lower (9) projection.
- each board is 120 mm long and 20 mm high.
- - Fig. 2 shows the joint (1) inside two boards one next to the other. In a practical solution, once the joint is inserted and the two boards (2) put closer, a gap (5) ; of about 7/8 mm is left.
- - Fig. 3 shows the boards assembled. In this phase, following the lateral pressure on the boards, the gap (6) remaining between them reduces to 3/4 mm.
- the joint takes different sizes according to the thickness and length of the boards.
- the first figure shows the pre-assembling
- the second figure shows the first phase of assembling, where the joint is fitted between the two boards
- the third figure shows the final situation, when the assembling is finished.
- Figs. 4, 5 and 6 show the same invention as the previous drawings where the joint has not a circular section but a polygonal section (IA), octagonal in this example. Consequently, also the two notches (4A) of the board have a corresponding shape, so that half the section of the joint fits into a notch and the other half into the notch of the next board (2) .
- Figs . 7 and 8 show two perspective views of a closed elastic joint consisting respectively of a cylinder and a polyhedron, equipped with a central hole. Said hole can be filled with foam rubber.
- Figs. 9 and 10 show two closed elastic joints, respectively of circular and polygonal shape, which connect three boards (2), with indication of the lateral (upper arrows) and radial (arrows in the centre of the boards) movement of the wood caused by its natural expansion towards the joint, which is able to cushion.
- Figs. 11 and 12 show a closed elastic joint, respectively of circular and polygonal shape, which connects two boards, with indication of the deformation movement of the joint (vertical and horizontal arrows near the joint) corresponding to the absorption of the lateral and radial movements of the wood.
