Description

LAMINATED RULER FOR FLOATING FLOOR COMPOSITION. Field of the Invention.

More particularly, the present invention relates to technical and functional improvements especially developed for the characterization of machined grooves configured on the four sides of a rectangular laminated rule, generally made of substrates, notably those known as HDF, density, and also HPP, high density particle board. Said machined grooves configure ideal mechanical means for coplanar coupling between several laminated slabs used in the formation of floating floors used in the most varied environments that support this type of floor, be they commercial, residential, industrial and others.

State of the art.

As is known, there are currently several types of floating floors, one of them is traditionally called high resistance laminate flooring or simply floating floor, whose main feature is that it is formed by rulers that combine different synthetic and natural materials. These rulers, in general terms, are mounted on a previously prepared surface, including or not acoustically and impermeable layers. In order to carry out the assembly on the surface, numerous rules are combined side by side which, for this purpose, have their longitudinal and transverse edges provided with a suitable type of fit. This type of docking may vary practically in two basic types: one of them is of the male and female type and requires the use of glue, while the other is of the self-locking type and it does not use the glue, as they teach, for example, the documents:

BRMU8502680U, BR U8800835U2, BRPI0606347A2,

BRPI0612187A2, BRPIO 621183A2, BRPI0802606A2,

US2002007606A1, US2002007609A1, US200315681A1,

US2003180091A1, WO0177461, O0179623, WO0201018,

WO02055809, WO02055810, WO03087498A1 and WO03089736A1.

Of course, all the above mentioned documents, cited by way of example only, present their constructive peculiarities, which meet with the respective advantages the formation of high resistance floating floors, however, it has been noticed that the fittings between one ruler and another, especially at the lateral edges , could be improved. considerably, so that the set could meet some advantageous objectives, especially in what if. refers to the coupling between the units, which is currently carried out only with the correct use of tension straps to approximate the longitudinal fittings, and further, said strap must be maintained for a certain time during the course of the floor assembly, ends up adding up more hours of placement and, in the end, the cost of the set turns out to be proportionately larger.

Objectives of the Invention.

The realization of a floating floor formed by laminated slabs mechanically joined through "hybrid" fittings machined with different angles that allow to fit together simply and quickly, defining an ideal rule for the composition of floors in commercial and residential environments, part of the installation being composed by the use of skirting boards and finishing profiles.

The main advantageous objective of the floor in question is its "hybrid" fitting system with different angles that allow to fit them together simply and quickly.

The longitudinal grooves of the ruler, besides the practicality provided, give two special effects: "traction" and "locking". Both obtained with the combination of different angles. Locking is achieved by the snap hook effect, while traction is the combination of inclined parts. The two effects combine so that the fit between two units is naturally performed and the inclined traction surfaces act as automatic calls to "increase the approach pressure" between the units, consequently making it possible to dispense with the use of traction belt, the which is substantially advantageous at the time of installation of the float.

Therefore, the rule in question does not require the use of tensile belts because the longitudinal grooves have angles that align and lock the floor slats themselves, allowing the tops to be fitted with the use of suitable tools to join the transverse tops. For these fittings it is necessary to apply glue between the fittings.

All fitting details can also be applied to any size ruler, especially those most adopted for such type of product, maintaining a rectangular pattern, for example, from 0.190 x 1.357 to 0.300 x 1.357 millimeters, whose thicknesses may also vary from 0.6 to 0.10 millimeters. Likewise, these rulers may consist of the combination of different known materials, including finishers, which are responsible for high impact resistance and kneading, where these substrates are coated with cellulose sheets which protect the product, give dimensional stability and also has the function of giving the decorative pattern to the floor, usually of natural wood.

Detailed description of the invention.

According to these illustrations and in more detail, more particularly Figures 1, 2 and 3, the present invention, LAMINATED RULE FOR FLOATING FLOOR COMPOSITION, is of the type traditionally in rectangular plate shape (1), manufactured according to any one of the preceding claims. dimensioning consistent with the purpose of the product, keeping a rectangular pattern, for example, 0,190 x 1,357 to 0,300 x ^'1,357 millimeters, whose thicknesses may also vary from 0.6 to 0.10 millimeters and further are made with different substrates responsible for high impact and kneading resistance, notably those known as HDF, high density fiberboard, and also HPP, high density particle board, coated with cellulose sheets that protect the product, give dimensional stability and also has the function of giving the decorative pattern to the floor, usually of natural wood.

Still with reference to figures 1 to 3, the rectangular plate 1 is coplanarly engageable with other equal units and, therefore, its transverse and longitudinal edges have peculiar groove profiles, all obtained by milling, where the ends or transverse edges have, respectively, the female end profile 2A and the male end profile 2B, while the longitudinal edges likewise have the female engaging profile 3A and the male engaging profile 3B, these and the foregoing impart engagement means (3A) and (3B) provide means for side-to-side coupling of the plates (1) without the use of a tensioning strap, while the profiles (2A) and (2B) are bonded with suitable glue.

As shown in Figures 4 and 5, the present invention is characterized in that initially the female engaging (3A) and male engaging (3B) profiles, when coupled, comprise:

- three levels of adjustment and coupling, an approach superior (4), a locking intermediate (5) and a support and traction (6);

the level of approximation 4, ordinarily vertical, is born in the upper face and develops downwards to approximately 1/3 of the height or thickness of the plate 1, as it is also defined by two adjacent faces of the two coupled plates , these two faces are symmetrical and have slightly inclined portions (6a-6b) and (7a-7b) interspersed by intermediate step (8 and 9), forming between them a substantially inverted V-shaped glue bag (10);

Below the glue bag 10 is formed the second or intermediate level of locking 5 against vertical movements between the two plates 1 defined on the male engaging side 3B by a tooth (11), which is generally trapezoidal, which finds a cavity of the same shape (12) on the side of the female coupling (3A), but said cavity (12) is of sufficient depth to form another collapsible bag (13) extending through under said tooth (11); and

- below the intermediate level of locking (5) there is formed the third level defined as traction and longitudinal locking (6) which, on the male engaging side (3B), is formed by a dug part (14) of the lower face of the (1) and, on the side of the female engagement (3A), this same part has an advanced edge defined as a support flap (15) which fits in said cavity (14) which in turn has. the upper side defined by a profile with a recess (16) and a tooth (17), both of which are generally trapezoidal, formed on the underside of the horizontal tooth (11), this same profile being repeated on the side or upper face of the support (18) and a distal tooth (19), wherein the first constitutes a recess for the tooth (17), while the distal tooth (19) meets engages the cavity 16 with a gap and formation of glue bag 20, which also repeats 21 at the abutment 6, where there is a complementary recess 22 at the bottom of the cradle 18, .

As shown in Figures 6 and 7 the faces 6a and 7a are also inclined at an angle of 87 ° and the combination of both forms a V-shaped space. 6 inverted and is trimpoint junction between the plates (1), below the same bonding pouch (10). This junction point 6 ^' has a permanent contact line between two plates (1) and the small angle of 6 ^' provides means for this line to be maintained even in the presence of small bends between the coupled plates.

The meeting point of the upper tooth face

(11) with the face (6b) is collapsed with a rounded recess which agrees with said face of the tooth (11) and a small inclined portion of 30 ° terminating in the face (6b), thereby eliminating breakage points. which also occurs with the cavity 12, where all the corners are rounded and combine with the corresponding roundings of said tooth 11.

The lower side of the tooth 11 has an inclination of 25 ° which also repeats on the underside of the cavity 12, while on the opposite side the cradle 18 terminates with a 45 ° inclination which constitutes the inner side of the tooth (19) and the corresponding side of the cavity (16) also with 45 °, these surfaces inclined at 45 ° constitute invitations for traction between two plates (1), which allows to eliminate the use of traction tape.

The glue bag 20 extends vertically and horizontally between the adjacent faces of the tooth 19 and the cavity 16 and, together with the other bag 13, form self-adjusting gaps between two plates 1 concomitantly with space for tailing.

The two adjacent upright faces of the tooth 19 and the cavity 16 have their lower edges equally beveled for relief of sharp edges. Figures 8 and 9 show the engagement between the sides 3A and 3B between two plates 1, whereby it is seen that the side 3Ά is receptive and invites the side 3B according to an angle of approximation. The coupling is completed after the slant plate is positioned in the same plane as the other, and at that time those 45 ° inclinations of the tooth (17) and the cradle (18) impart a pulling effect between the two plates, providing a fine adjustment (18) and (16). The locking of the teeth (11) and (17) in their respective recesses (18) and (16) is effected simultaneously.
