MECHANICAL CONNECTION OF PAD LASER FLUID

FIELD OF THE INVENTION The present invention relates to an interface system for a mechanical connection of floor elements to a connecting plane, the core, the walking surface, the backside, and the opposing edges of the floor spheres, which are formed as a tongue groove, delimited by the upper and lower lips, and the lower side, and the other connection is provided. wind is formed as a tongue having an upwardly extending portion at its free end and a tongue, a

In the plane of connection W, an undercut groove having an opening, an inner portion and an inner sealing surface, and at least some parts of the lower lip are formed with the core of the floor element, and the tongue has a closing surface which is configured to cooperate with the adjacent member. with an internal closing surface in the groove of the floor element. when the two floor members are mechanically connected to each other so that their walking surface (4a, 4b) is in the same plane and meet in a plane perpendicular to the running surface.

The invention is particularly suitable for use in parquet floors which are essentially made of wood and generally have a core of wood and can be mechanically coupled to one another. they are directed to the field of application and, above all, to angular parquet flooring elements that are connected to each other on both long and short sides. In particular, the invention relates to floating pavements, i.e. to surfaces that can be displaced relative to the base floor. However, we must emphasize. that all types of hard floors of the present invention can be used, such as homogeneous adhesives, wooden floors with a laminate or laminated core, and floors having sheets of their surface and fiber core, and thin laminate floors, and floors with core is made of plastic, etc. Of course, the invention can also be applied to other types of floor elements which can be machined on cutting machines such as pads made of laminated sheet or press plate. Even if this is not practical, the floor brackets can be fixed to the socket after assembly.

§SIZE-2S3SA /; - 'T-Kc

Mechanical joints have quickly shrunk to a high market share, mainly due to their excellent laying properties and the strength and quality of their joints. Even if the Wö 9428999 described below and the Alloc trademark have many advantages over conventional glued floors, further improvements are still desirable in this field.

Mechanical coupling systems are very suitable not only for joining laminated floor panels, but also for joining wooden floor elements and composite floor elements. Such floor panels may consist of a large number of different materials on their surface, as well as on their cores and back. As will be described in more detail below. these materials are also used for different parts of the Injection System, such as woods, closures

IS and language. However, WO 9428999 or Wö 9747834 discloses an integrated belt-based solution that provides horizontal bonding and has a tongue that forms a vertical linkage, resulting in additional costs, particularly as a result of the generation of waste material. mechanical joints are formed from the material of the floorboard.

In order to achieve the best possible performance, for example, a 15 mm thick wood frame beam should be a strip whose width is almost the same, or approximately as large as the floor slab, e.g. about 15 mm, for a 3 mm tongue; loss, ie waste material 19 mm,

The usual width of the parquet is around 200 mm. As a result, the waste material is approx. 9%. In general, the cost of waste material increases if the parquet elements contain expensive materials, or if they are thick or small, so that the number of joints per square meter of floor will be large.

Of course, the amount of waste material can be reduced if a tape is used that is a separately manufactured aluminum strip that has already been fixed to the flooring in the plant. Moreover, the aluminum strip provides, for many applications, a better and cheaper connection system than a tape that is made from the core. However, the aluminum strip is not very advantageous since the investment cost can be significant and the extensive conversion of the plant may be necessary to transform the existing traditional production line so that it can be produced with such mechanical cast acoustic systems. BACKGROUND OF THE INVENTION The prior art is Siamese aliominium tape

However, one of the advantages of this is that the starting form of the flooring need not necessarily be needed.

In the event that a strip is formed by machining the material of the floor element, the position is reversed so that the shape of the floor member should be designed to provide sufficient material for the ribbon and the tongue. Laminated O floors often require changing the width of the decorative paper used. All of these costly changes to the regulations and changes to the production equipment and the product line of production are affected.

In addition to the above problem, which is associated with unpleasant material loss and production costs, and with the adaptation of production, the tape also has the disadvantages of being sensitive to, for example, transport and assembly injuries,

In summary, there would be a great need for a mechanical coupling system that has a lower production cost, while maintaining excellent properties for laying and picking quality and strength. In practice, it is not possible to achieve low cost without compromising on strength and quality of the laying function. It is therefore an object of the invention to provide a killing that can reduce costs while maintaining strength and functional properties at the same time.

The present invention is based on known floor elements having cores, faceplates and backs, and opposing connecting edges,

3 of which one is formed as a tongue groove having upper and lower lips and has a lower part, and is configured as the other tongue at the free end of the upward portion, The tongue groove is a recessed groove with an opening, an inner portion and an inner portion. At least some parts of the lower lip are integrally formed with the core of the floor element, and the tongue has a closing surface that is configured to contact, and cooperate with the inner sealing surface in the tongue groove to be attached thereto when the two pads are mechanically sloped. This technique, which is disclosed, inter alia, in DEA-3041781, is a well-known technique which will be described in detail below.

Prior to this, however, the joining system for mechanically assembling and connecting the floor elements, as well as the technique of fitting the fitting elements 10, will be described in detail as the prior art of the present invention.

In order to facilitate the understanding of the description of the present invention and the description of the problems behind the invention, a description is provided herein which includes the function and basic design of the flooring according to WO <RTIgt; 426999 </RTI> and WO 9966151. Figs. The following description of the state of the art with respect to the applicable parts can also be applied to the present invention as described below.

The 3 a. and 3b. Figures 1 to 4 depict a pad2Ö element according to WO 9426993 from above and below. The floor element 1 is angular such that it has a top solution 2, a bottom solution 3, and two opposing longitudinal sides, on which connecting edge portions 4a and 4b are formed, and two further opposing shorter sides having engaging elements 5a, 5b;

The sides 4a, 4b of the longer sides, and the shorter sides 5a,

The connecting elements 6b can be mechanically connected to each other without the use of an adhesive. Figure 2c is a plane VP connection (shown in FIG. 2c), and its first pages in a reciprocating plane are in a common HP plane as shown in FIG. 2c. shown in FIG.

In the illustrated embodiment, which is a floor element according to WO 9426399 (Figures 1 to 3), the floor element 1 has a factory-mounted flat strip 6 that extends along the entire length of the portion 4a and is made of a flexible aluminum sheet. The tape 6 extends beyond the contact plane VP at the portion 4a. The tape 6 can be mechanically coupled to the shape shown, or otherwise, such as an adhesive or other solution. As disclosed in said patent document, it is possible to produce the tape or the tape from a material that is fixed to the flooring in the factory, and even other materials. such as a metal plate, aluminum or plastic sections. As discussed in WO 9428999, and as disclosed in WO 9986151, the tape 6 may instead be integrally formed with the floor element 1, for example by machining the core of the floor element 1 accordingly.

In particular, the present invention is applicable to floor elements, wherein the strip or at least a portion thereof is integrally formed with the core and the invention addresses specific problems that arise with such pushing members and in the manufacture of such floor elements. may be made of the same uniform material. However, the strip 8 is always in one piece with the floor element 1, for example it can be formed on the floor element or mounted on the factory.

According to one of the known embodiments described in W0 9428989 and WO 9986151 S2, the strip 6 has a width of 30 mm and a thickness of 0..5 mm.

A similar, albeit shorter, 6 'strip is arranged along the shorter 5a connecting element of the floor element 1. A portion of the strip 8, which cries out, extends beyond the protrusion plane VP, has a closing member 8 extending along the entire length of the strip 8, a closing surface 10 on the lower portion of the closure 8, which faces the attachment plane VP and its height, e.g.

8.5 mm. Lined with this closure surface 10 cooperates with a closing groove 14, which is formed on the lower side 3 of the longitudinal side 4fe of the opposing longitudinal side of the connector szalag, the strip 8 'is provided with a corresponding closure member 3' and the opposite shorter side. The connecting element Sb has a corresponding groove 14 '. The edge of the closing edge of the barrel 14, which looks from the VR connector plane to the other direction, forms a working 18 'closing surface that cooperates with the working 18 zero surface of the closure.

The mechanical connection of the long and the shorter sides in the vertical girl (Figure 1c is shown in Figure 1c by way of the longitudinal side of the floor element 1 (strand 4a) and the shorter side (connecting element 5a) is a laterally open groove or 16 tongue grooves are formed, bounded upward by an upper lip at the edge portion 4a, and by the connecting element 5a and downwardly by an appropriate band 6,6 '. It consists of 20 closing tongues which cooperate with the tongue groove 16 (see Fig. 2a).

The la. -1c. 1 to 4 show how the two floor elements 1.1 'can be connected to each other by means of a longitudinal edge portion 4a, 4b being hinged around a center C at an angle close to the intersection of the HP surface and the connecting plane VP; holding the floor elements substantially connected to each other.

A 2a. - 2o. 1 to 5 show that the floor elements 1, V are short-circuited 5a. Connecting elements 5b can be connected to each other by a bepatnnto operation The longer edge portions 4a, 4b can be connected by both methods, whereby the shorter connecting elements 5a, 5b after the first row of bearings are laid down in a conventional manner - just by clicking on the longitudinal side 4a. , 4b are connected to each other first.

When a new floor porch 1 'and a previously laid floor 20 element are to be connected to their longitudinal side portions 4a, 4b, as is the case of the wood. - fc, shown in the diagrams, the longitudinal divide of 4 b, which is on a Γ floor panel, pushes the heater of the previously laid floor element 1! 4a to 4a of FIG. 4a, such that the closing tongue 20 is inserted into the tongue groove 16. Subsequently, the support element f is held at an angle downwardly to the base portion 1b. as shown in FIG. The closure 20 completely enters the groove 16 while at the same time the sealing element 8 of the strip 6 engages in the closing groove 14. During the described downward bending, the upper portion 9 of the closure 8, or the upper portion thereof, guides the paddle in the direction of the previously laid down element 1.

1c. Fig. 1B shows the paddles 1, T are securely fastened in direction 01 and 02 in the direction of longitudinal flanges 4a, 4b, but floor elements 1 Γ can be moved longitudinally relative to each other along their longitudinal sides (i.e., in the direction 03).

A 2a. ~ 2c. Figs. 1 to 5 show that the connecting elements of the short side 5a, 5b of the floor elements 1, 1 'can be connected to each other in a chronically D1 direction and in the direction of D2, the new & p & d < 1 &gt;

Compared to S. This is especially the case after you have connected the long side of the em floor plate to La, ~~ 1c. Figures 1 to 4 show an inward angle to the previously installed floor element 1 in a connecting line. The 2a. 1, the sloping surfaces of the tongue groove 18 and the closing tongue 20 cooperate. that the tape 10 '6' is pressed down by force, which is a direct consequence of the fitting of the short engaging elements 5a, 5b to each other. During the final assembly, the strip 5 'engages when the closure 8' penetrates into the connecting groove 14 ', so that the operative closure surfaces 10, 10', which are on the closure 8 'and engage in the closing groove 14, engage with each other,

IS The La, ~~ fc. Figs. 2a. - 2c. 1 to 3, the entire pad can be laid without the use of an adhesive and all of the connecting flanges, the prior art floor members of the prior art are mechanically connected to each other according to the rules of laying, at an angle; holding downward on its longitudinal side, and the lateral longitudinal sides are already attached, i.e. secured, and snap together by the horizontal displacement of the new pad 1 '; already laid along the longitudinal side of one of the pillars (direction D3). The floor elements 1, Γ, without damaging the joints, can be picked up in a sequence contrary to the 25 order of deposit and can be reloaded. Some parts of these deposit principles can also be applied to the present invention.

The prior art padleefemekef to be optimally operable and allow easy lay-up and re-picking, should be placed after a long side of the buckle in a position 30 with a small play between the closing surfaces 10 of the operating closure and between the sealing surface 10 'of the operating sealing groove 14. However, there is no need for a backlash in the VP connection plane near the upper surface of the floor elements at the juncture contact (i.e., the HP surface plane) between the floor beads. In order to achieve this situation, one may need to press the padloelam to the other. A more detailed description of this backlash can be found in WO 9426989. This backlash can be in the range of 0.01 to 0.05 mm between the operating seals 10, 10 'when the longitudinal solution of the interconnected floor panels is pressed together :, This backlash facilitates the entry of the locking elements into the groove 14,14' As mentioned above, there is no need for back play when contacting floor surfaces. The HP surface plane and the connecting plane W intersect each other in the upper half of the floor element.

The connection system allows movement between the contact flanges 10 in a closed position after any side is connected. As a result, the laying can take place in many different ways, including all variations of the basic procedures:

> Long Shutdown Adjustment and short side sticking;

> long side snapshot - short solution snapshot:

> adjusting the short side angle, adjusting the two floor elements at an upward angle, moving the new floor element along the shorter side of the previously laid pillow, and finally adjusting the two floor elements downwards;

The most common and safest lay-out method is to set the beef-like side first at a downward angle and to connect it to another padloom. Subsequently, in the closed position, a displacement is made towards the short side of the third pad so that the shorter side is snapped. The laying can be done along one side, along the long or the shorter side, with the joint of another additional pillar. Then, in the closed position, a displacement is made until the other side slams into a third floor element. These two methods require at least one side of the pinch, however, the laying may be snap-locked. The third option is to bend the shorter side of the first pile first inwardly toward the shorter side of the second floor element, which is already battled along its longitudinal side along a longitudinal side. for the third padioeism. Once assembled, the first and second pads are bent at a slight upward angle. The first floor element is displaced in an upward direction along the side of the mvideb strip as long as the first floor element and the upper contact edges of the bar15 floor element are in contact with each other and then the two floor members are bent in an inclined manner.

The above-described floor element and fastening mechanism, or its system, has been extremely successful in the market for laminated floors having a thickness of about 7 mm and an aluminum strip 8 having a thickness of about 0.8 mm. Similarly, the commercial versions of the floorboards according to WO 9966151, which are shown in FIGS. 4a, 4b. also shown. However, it has been found that this technique is not sufficiently suited to floor elements made of wood-fiber-based material, especially massive wood or glued laminated wood to form a parquet, parquet surface. One of the reasons why this Known Technique is not suitable for depositing such products is the large amount of waste material that is generated during machining of the sections when the tongue groove is formed at the proper depth. In order to overcome this problem in part, it would be possible to use a technique that is in accordance with FIG. and 5b. Figs. 4A and 4B, which are disclosed in DE-A-3343601, that is, it would be possible to separate the two edge edges of the elements, which are connected to the longitudinal flanges. This technique also requires the use of expensive pieces of aluminum and a significant amount of machining, furthermore, it is difficult to connect the batch elements along the edges in an economically efficient way. Furthermore, the geometry shown does not allow the installation and dismantling without significant costs by pushing the batteries up and down. because the parts do not separate from each other during these movements, when they are made with very tight fitting (see Figure 5b).

Another known padloeem design is shown by a mechanical lilies system in FIG. ~ 8d. 1 to 4, which are described in CA-A-0991373. When this mechanical tensioning system is used, all forces that try to extend the longitudinal sides of the floor members are applied to the closing member at the outer end of the belt (see FIG. 6). When laying or picking up the floor, the material must be resilient to allow the tongue to loosen by rotating around two centers at the same time. The tight fit between all surfaces makes it impossible to make rational production and move in a closed position. There is no horizontal closing of the shortcut page 6c.

This type of mechanical closure results in a large amount of waste material due to the design of the large closure.

A more well-known mechanical closure design for flooring beams is shown in G8-A-1430429 and in section 7a. -? h. The system is essentially a tongue groove coupled with additional support hooks on a protruding lip on one side of the tongue groove having a corresponding support rib formed on the upper side of the tongue. The system requires considerable flexibility from the lip on which the hook is disposed. and the disconnection cannot be performed without damaging the flanges of the mounting element. The extremely tight fit makes the manufacturing process difficult and the geometry of the connection results in a large amount of waste material.

Further known artistic deformation systems for known psdeters are described in DE-A-424253. Such a ligature system is shown in FIG. - 8b. also shown in FIGS. However, this Known Bonding System has several drawbacks. Not only large amounts of waste material are produced during production, but it is extremely difficult to create economically high quality joints that are required for high quality floors. The undercut groove, which is formed by the tongue sand, can only be formed by a milling cutter which moves along the connecting edge. Thus, it is impossible to use large-sized disk-shaped cutting tools for machining floor elements from the side rim.

There are many suggestions for mechanically assembling different types of floor elements, especially for padioes: where the amount of waste material is small and where the factory tree is economically feasible even when using a pressed sheet or press-based floor material. Thus, WO 9627721 (see Figures 9a to 9b) and JP 3189987 (see Figures 10a.10b) illustrate two types of snap-fit designs which result in small amounts of waste but have the disadvantage of having a small amount of waste. . to make it impossible to dismantle the underlays with half-hair, True. however, these coupling systems can be economically produced with large discs: disk-shaped cutting tools, but have several drawbacks, since disassembling at the upward bending can seriously damage the joint tensioner and prevent the floor element from being fixed once again by mechanical fixation.

Another type of system is that described in DE-A-1212275, and 11a. - 11b. Figs. This known system is suitable for sports floors made of plastics for the production of sports floors and cannot be produced by large-scale disk-shaped punching tools to form sharp undercut grooves. This known system, too, can neither be disassembled by upward displacement without the highly elastic material in which the upper and lower lips encircle the undercut groove does not deform to a large extent while pulling them apart. Such a type of bonding is therefore not suitable for the production of floor elements which are press-based on plates if good quality joints are desired?

The MS-A-1124228 Publication Document also proposes tongue-and-pin connections with an inclined groove and tongue. The type of connections that are 12o. Figures illustrate the connection of a new floor element by pushing it down over an oblique upward tongue which is located on a previously laid floor. In order to fix my newly laid floors, they use nails that are slanted downwards, and are fed into the paddler? over the inclined upward tongue, A 12a, b. In the embodiment shown in FIG. 1, this technique cannot be used because a dovetail joint has been used. This technique will certainly result in a small amount of waste material, but is not at all suitable for floating flooring having separate floor elements without being damaged, assembled and disassembled in a very simple manner and having good quality bonds,

DE-A-3041781 discloses a joining system for attaching skirting elements, in particular to roller skating stadiums or pole poles made of plastic. Such a connection system is shown in Figs. 13a, d. FIGS. The system comprises an undercut longitudinal groove along the edge of the floor superstructure, and an upwardly curved tongue formed at the opposite edge of the floor edge. In the cross-section, the first portion of the underfloor groove is formed, which is formed by parallel surface portions and parallel to the main plane of the floor element, and a second inner portion,

-12 ”is a trapezoid or a half trapezoidal cross-section (see Figures 13a-b and 13c). In cross-section, the tongue has two parallel planes which are angled relative to one another, and wherein the portion closer to the center of the floor member is parallel to the principal plane of the floor element and wherein the outer free portion is angled upward with the corresponding plane portion in the trapezoidal portion of the undercut groove. .

The edges of the tongue and groove, as well as the edges of the floor member, are such that, when two such floor elements are mechanically connected, the formed connection is between the surface portions of the tongue and the corresponding surface portion of the undercut groove along the outer end and the entire upper side of the tongue, and along the lower part of the inner parallel portion of the tongue and, on the other hand, under the flanges of the joined floor elements and the groove and the tongue. When a new floor element is connected to a previously laid floor element, the new element is bent upward at an appropriate angle to the oblique outer portion of the tongue for joining with the outer parallel plane portion of the groove of the previously laid floor element. Then, the tongue is inserted into the groove while the new floor element is bent downwards. Due to the angular shape of the tongue, a considerable amount of back play is required on the first portion of the groove to allow this fitting and movement in the inward angle20. In the laid-in position, a connection is formed between the main parts of the tongue surfaces and the undercut groove, except under the angled outer upward portion of the tongue.

Mechanic according to DE-A-3041781

The major disadvantage of the system is that it is extremely difficult to produce. A preferred method of production is the use of a mushroom head, the outer part of which forms a trapezoidal inner part of the tongue groove. Such a manufacturing process is unreasonable and also causes major breakage problems when the manufacturing process is applied to floor elements or other elements made of wood, for example, to produce panel elements or parquet elements having good quality joints.

As mentioned above, one of the drawbacks of this prior art solution or mechanical shear is that the insertion of an angular tongue into the groove has a significant amount of back play. The tongue and groove are required (see Fig. S for QE-A). 3041781 and attached FIG. 13b) for bending downward angles, if there is, in fact, no corresponding or substantial flexibility in the material of the floor. Furthermore, such a downward bending cannot be performed while the new floor element and the previously laid floor element are assembled in such a way that they are in contact with each other over the upper edge of the floor elements or near the upper edge of the tongue and groove so that the downward bending occurs the center of its wrist movement is at this point.

The further mechanical disadvantage of the mechanical joining elements according to the present invention, according to ÖEA 3041781, is that the displacement of the novel elements in the case of thick wooden pallets in the same direction as the previously laid down floor element is much more difficult for the interconnected pads. on the large surfaces. Even if the wood flooring work or machining of base blocks made of wood-based presses were performed accurately, these surface parts are not smooth enough for natural reasons but have protruding fibers that significantly increase friction. When laying flooring or similar elements, the length of floor elements (often 2 to 2.4 mm long or 0.2 to 0.4 m wide floor elements) and essentially natural materials are used. These types of long floor elements are overwhelmed and, as a result, they would often deviate from the fully smooth tree (with its banana shape). In these cases, it is even more difficult to move the newly laid floor element along an already laid floor element, if a mechanical fitting system is to be used at shorter edges of the floor elements.

A further disadvantage of the mechanical bracing system described in DE-A 3041731 is that it is not suitable for high quality floors made of wood or extruded sheet and consequently require a close fit between the tongue and groove in a vertical direction. In order to prevent flooring: WO 9747834 discloses different types of mechanical joining systems provided. A pad10

Connecting systems for securing the longitudinal sides of the IS elements (see Figures 2 to 4, 11, and 32 to 25 in said document) are designed to be assembled and disassembled by a coupling and an angular displacement, while many one of them serves to align the shorter edges of the floor elements (He, - Figs.) and they are designed to be connected in a transverse direction to each other and sealed by the closure, but these soldering systems may not be disassembled on the shorter sides of the floor elements. without destroying them or, in some cases, becoming totally inaccessible.

Some of the bedding elements disclosed in WO 9747834, as well as those for disassembly and assembly, operate at an angular displacement (Figures 2 to 4 in Figures WO 9747834 and 14a-c in the annex to the present invention), and one edge has a groove and a ribbon extending under the groove and extending beyond the engagement plane where the two assembled pads meet the upper part. The strip is configured to cooperate with a substantially complementary part of the floor element. on the other edge so that two similar floors can be assembled. The common feature of these floor elements is that the upper side of the tongue and the corresponding upper boundary are flat and parallel to the groove of the groove, or the elongation of the cushion element. The connection between the cushion elements to prevent them from being pulled safely transversely to the interlocking plane , such that it is only accessible by means of closing surfaces on the lower part of the tongue and on the upper side of the lower lip of the strip underneath the groove. This spraying system also suffers from the disadvantage of requiring a band portion that extends beyond the connection plane and consequently produces waste material within the contact edge portion where the groove is formed.

WO 9747834 also discloses a mechanical coupling system consisting of a circular tongue and a correspondingly formed groove formed on the opposite side of the floor element (Figs. 14d to 14e). When such an annular system is connected, the tip of the tongue is inserted into the slot of the curved groove and the downward bend begins thereafter. Meanwhile, a large surface contact between the tongue and groove surfaces of the groove is formed during the downward bending. If this type of coupling systems were used to assemble long wooden or wood-based elements, it would be difficult to match them smoothly and 10 times. In addition, the sourlooas require significant forces between the tip of the arched tongue and the tongue, as well as the bottom of the groove, to disengage one of the floor elements from one another in their joined position. This technique, known in the art, is clearly better than that disclosed in DE-A 3041781, but has several drawbacks.

US-A-2740167 (see Figures 15a-b) discloses a parquet tree blanket made of wood and having opposing edges formed with portions that are hooked and interlocked when laid in a plurality of flooring rows. One of the flanges has a downward slope, while the opposite flange of the flange is an upwardly extending groove. In order to allow the insertion of a new floor element under a previously laid element, the bottom side of the upward hook is tapped. The floor elements, which are connected to each other in a vertical alignment plane, are simply fixed in a horizontal direction perpendicular to the connection plane. In order to fix the elements vertically, that is, to be fixed in a direction perpendicular to the upper surface of the floor element, an adhesive layer is applied, which is previously laid on the substrate on which the parquet is to be arranged. A previously laid parquet element should therefore be re-raised or raised, but before the adhesive layer has cured, such a parquet; therefore, it is permanently attached to the substrate after laying.

CA-A-2252791 discloses parquet elements. It also shows that they are provided with special grooves along one of the longitudinal sides and with a complementary tongue along the other longitudinal side. As can be seen in the patent, and ISa attached to our application. -b, in the diagrams, you, the tongue and the groove are rounded and at an inclined angle, the tip makes it easier to mount one of the padlades on the other floor element, so that the mountain parcel the new parquet element close to the laid parquet element and then both together. lifted and angled, after which the groove is pulled downward to the tongue, while at the same time joining and moving the parquet element Mfvei the tongue and groove are complementary, it is very difficult to make the connection and maybe even fold apart the parquet tree together. deviation from the plane, i.e., for example, banana agility, results in the formation of an additional barrier before the two parquet elements are assembled, the risk of damage to the tongue is therefore high and the design also results in high frictional forces. and the groove surfaces garden

The

US-A-5797237 discloses an articulation system for assembling floor elements, Fig. 17a shows two assembled floor panels in section section 17b, and a known floor element in Fig. 17b, which cannot be disassembled by tilting the floor panel relative to the other floor element that is already down. invested. Instead, as shown in FIG. 43 in said disclosure document, both floor elements must be removed and the floor element to which it is attached, which remains on the ground or remains on the substrate, should be lifted to pull the tongue out of the groove. The system exhibits a high degree of similarity to that disclosed in US-A-2740167 (Figures 15a-fe), but with the difference that the shorter lower lip is formed under the hook-like projection or shape. This shorter lower lip ductal wall does not produce a coupling effect, with a gap between the lower part of the tongue and the upper side of the short lip when the two floor members are assembled. However, this small gap is required to disassemble as shown in Figure 17. Of course, it is stated in the disclosure document that the coupling system is a snap connection, but it is likely that the laid padloom leans slightly upward to leave the tongue under the lips of the floor floor. This mechanical deformation system, as can be seen in the aforementioned patent, can be manufactured with a large disk-shaped cutting tool, there are no cut grooves 10 below which the upper or lower lips would collide with the inserted tongue and close the tongue in a vertical and horizontal direction. in this interface system. Thus, the groove is large in size in the vertical direction or larger than the corresponding parts of the tongue. The laid floor element can therefore move from the substrate, causing squeaking at the joints and unacceptable vertical movements. Due to unsatisfactory closure, a high quality bond cannot be formed.

The patent publication FP-A-2875174 discloses a mechanical coupling system known for ceramic tiles having complementary opposing flange portions, in which case separate spring clamps are used which are spaced apart at a distance and serve to grasp them. The connecting system is not designed to be disassembled, which is apparent from FIG. 18a. and, in particular, FIG. FIGS.

The 19a. and 19b. Figs. 1 to 5 show a panel of floor panels according to the art of JP 7180333. After assembly, it is practically impossible to disassemble such a floor panel due to its binding geometry, which is evident in FIG. Fig.

Finally, FIG. and 20b. Figures 1 to 4 illustrate a further switching system disclosed in GB-A-2117813 and intended to connect large-sized insulated wall panels. This system is very similar to the system described in CA ~ A ~ 2252791 described above, as well as to a system known from WO 9747834 and as shown in Figures 14d and 14e. The system has the same drawbacks as the latter two systems and is not suitable for the production of wood or pressed board floor panels with high efficiency, especially for making high quality joints that are required for high quality floors. as elements and cannot be opened with upward access.

18 As it is evident from the above, prior art systems have both advantages and disadvantages. However, there is no joining system that is well suited for the rational production of floor elements with an illumination system that is optimal from the point of view of manufacturing technology and for waste materials, for depositing and reclaiming functions, and which can also be applied to floors that need to be of good quality and have a solid functional property having a proper functional property,

An object of the present invention is to satisfy this need and to provide an optimum connection system for floor elements in which such optimum floor elements can be used. A further aspect of the present invention is to provide a rational method for manufacturing floor elements with such an attachment system.

Good quality osabacosa

The term "high-quality connection" means a close fit between the padloe elements. In its closed position, it is both incisive and horizontal. Possibility: to mount, the floor elements are connected to each other without very large visible gaps or differences, where the differences are level differences, both in the unloaded and in the normal load, between the connecting edges. In the case of high quality cushions, the joints and gaps must not exceed 0.2 and 0.1 mm.

Shuffle / Shutter Rotation / Chatter / Shuffle Watch

1S

As soon as it becomes apparent from the following description, the closure can be at least one side, preferably along the long side, by downward flushing. The downward-facing tree may be rotated around a center close to the surface plane of the floor element and the intersection line of the contact plane, i.e. close to the top contact edge of the padloes when they are joined together. Otherwise, it is impossible to create an Adapter that results in tightly fitting edges.

It should be possible to complete the rotation in a horizontal position, in which the padloids are closed vertically without backlash, which makes the backlash undesirable level differences between the contact edges, the inward bending must take place in a way that simultaneously guides the floor elements towards each other and closely it fits any matching shape of the banana (ie the deviation from the straight, smooth shape of the floor element). The closure and the closing groove must have conductive elements that cooperate with each other during the downward bending. The downward bending must take place with great security without the floor elements engaging or snapping into each other, which would risk the damage to the body,

Aa / fo / ya hayf / t

It must be possible for the longer edge to bend upward to separate the floor elements from each other. Since the floor elements are in very close contact with each other in the Hindu position, with particular regard to their edges, this upward access must in any case occur when the upper connecting edges are in contact with each other and the rotation takes place around the connectors. it is very important not only when changing floor elements or moving the floor, Many floor elements are only put to the test or are not positioned exactly next to the doors, at the corners, and so on. during placement. It is a great disadvantage that if the floor element cannot be easily picked up without damaging the attachment attic, the situation is not always that which can be bent in the floor element, it can also be bent upwards. In the downward bending, a slight downward bending of the lid closes backwards, and then downwards and opens. If the coupling system is not formed with proper angles and radii, the pad member closes after depositing in such a way that it is impossible to pick up, A. short side after being extended by a longitudinal engagement with an upward movement, can be extended along the contact edge, but preferably if the short side can be opened upwards. This is particularly advantageous when the padding elements are long, for example, 2.4 m long, which makes it difficult to pull the short side up. it can hide itself.

csepananas

It is also possible to close the short sides by horizontal hammering. To do this, the coupling system must be flexible and flexible. Even if the length of the long sides inwardly bending is much easier and faster than the snap, it is advantageous if the long side can be snaped in as it is laid out! for example, around the door, it is necessary to have the floor elements horizontal

Material costs are long and short ocher

For example, if the floor element has a size of 1.2 * 0.2 m, the floor area of 30 square meters contains about six times more longitudinal connections than a short side connection. As a result, large amounts of waste material and costly joints have less importance on the short side than on the long side,

Wzsz / nfes number

-28It is in the interest of achieving high strength that the closure must normally have a high closing angle so as not to puncture the closure. The closure must be high and so wide that it does not break when subjected to a high tear load or tension as the floor stretches in winter due to the low humidity characteristic of this period of the year. This also applies to materials close to the closing groove. The short side binding should have a higher strength than the long side bond, since the tensile application during the winter contraction is distributed in the shorter bonding along the short side rather than along the long side.

We must allow the floor elements to be held flat when exposed to vertical loads. Furthermore, the movements in the bonding must be avoided, since surfaces which are subjected to pressure and which are displaced relative to one another, such as the upper joint edges, may cause creaking or cracking.

Eímozdrtőafőság

In order to create the possibility of mounting on all four sides, it should be possible for a new floor element to be laid in a closed position with a pre-laid flooring element. This displacement should be carried out using a reasonable amount of force, such as guiding a body and a hammer together, without damaging the joining edges and without causing the switching system to be horizontal and vertical with visible play-offs. more important on the longer side than on the shorter side, because the friction here is significantly higher considering the longer bonding.

Manufacturing It should be possible to make coupling systems that use reasonably large rotating cutting tools that have extremely high accuracy and capacity

In order to achieve good functional manufacturing areas and quality, the connecting profile must be continuously measured and checked. Typical parts for mechanical joining systems are designed to make manufacturing and measurement easy. It should be possible to produce them with a few hundred mm of aperture and therefore be able to measure them with great accuracy, for example, me. profile project help If the connection system is formed by linear cutting, the connection system will have the same profile as the complete flange, except for certain manufacturing fractures. As a result, the piercing agent can be measured with high precision by cutting out a sample. the

measured here with a profile prector or a measuring microscope. Reasonable manufacturing nevertheless requires that the coupling system be quickly measurable and easy without the use of destructive methods, such as gauges. This becomes easy if the critical parts in the recording system are a small number of small numbers only for the length of the leA and the short side;

In order to create the optimally prefabricated floor elements, lifting slings can be produced at a minimum cost, long; and the. For example, the long side should be optimized for downward bending, upward bending, positioning, and movability, while the long side should be optimized for hatching and high strength. An optimally designed

2O floor element therefore has different connecting elements on long or short sides,

Possibility of joining a cross-cut cross section

Wood-based floor elements and floor panels that are substantially and generally the floor panels that contain wood fibers are contracted or expanded due to relative humidity changes. Expansion and contraction usually begin from above, and the surface layers consequently; they move more, the core is the part from which the connecting system is trained. In order to prevent the top connecting edges from rising or high swelling,

The expansion system should be crushed as a result of the expansion, or the connecting slots protrude when they dry, so that the coupling system is designed to allow movement that compensates for shrinkage and swelling.

The prior art systems shown in Figures 9 to 18 can be manufactured with mechanical joints with less waste material than mechanical tensioning systems provided with protruding and machined strips. However, none of these satisfy the above-described requirements and does not solve the problem that has been solved. the present invention is

The snap connections 10 of Figures 9, 10, 11, 12, 13, and 18 can be opened or closed by the movement of the wrist eye on the upper part of the contact or connector edge, and the joints according to Figs. floor element with material machining with rotating machining tool with large diameter.

A 12a, - d. Figs. 1 to 5 are not curved or snapped, but firstly, they can be pressed in parallel with the connecting edge. 12c. - The binding shown in Figs. While it is possible to bend it inward, in this case the joining system has to be formed with too much back play, the vertical strength is low because the upper and lower contact surfaces are parallel. Furthermore, the bonding is difficult to produce and in the closed position of the cotyledonate since it does not contain free surfaces. However, it is advised to be attached to the socket with nails that are perpendicular to or inclined to the floor tufts over the inclined upward tongues.

The Cock, D, and the 15th Century ~ b. and a connector according to Figures 17a, b

2S systems show examples of joints that do not have a vertical closure, i.e., allow the wearer to be positioned perpendicular to the upper surface of the floor member,

The inwardly foldable engagement of FIGS. 14d to e has a number of drawbacks, as it is manufactured and designed on the basis of the principle to form a tight body, and the tongue and groove follow a circular center with the center of the tongue and groove. it has a top connector edge. that is, the binding and upper surfaces of the mural, This bond does not provide the necessary guiding elements, and the bonding is difficult to bite together, since it is not precise in design and is too large for the size of the contact rests. As a result, spray and so-called. it also produces a drag effect during inward bending. Its horizontal strength is too small, which is a low top closure, and the too small angular ribs depend on the top and bottom contact surfaces. In addition, the front and top upward curved portions of the tongue groove are too small to withstand the forces necessary to form a high quality knitting or coupling system. The excessively large contact surfaces between the tongue and groove and the lack of free surfaces that are not in contact, as well as the tight adherence requirements in the entire bond, are the lateral elements of the floor10; This leads to a rather difficult shift in contact with the contact elements and, as a consequence, the possibility of rational, rational manufacturing, and the ability to achieve good tolerances during manufacture. These systems cannot be squeezed in the direction of color,

16a. ~ b. 1 to 3, there is no arrangement for joint displacement without substantial material deformation, which is difficult to achieve for commonly used flooring materials suitable for flooring applications. In this case, all the parts of the tongue and groove are connected to one another20. This makes the lateral displacement of the floor element in a closed position difficult or impossible, rational machining is impossible, since all responses are in contact. No snaps can be realized.

6a. - b, system sys- tem connection system cannot be coexisted with .haj25, because it is designed to rotate around two pivot points simultaneously. Horizontal Closure in the Language Slot. Each surface is in contact with another surface, tightly. In practice, this patchwork cannot be moved and rationally machined. This system is capable of being used in a boom system which is in accordance with FIG. and d.

Figs. 3 and 4 are formed on adjacent perpendicular edges of the floor element and do not require lateral displacement for connection.

A Se. - b. 1 to 4, there is a groove which cannot be machined in a rotating rotary filter having a large diameter. Mern is snap-on and is designed to prevent lateral displacement due to Initial Impact Force and tight fit adjacent the outer vertical portion of the belt.

5a. - b. Figs. With rotating fergoat tools that have large tool diameters, the tongue is unrealistic. The coupling system A is designed to be incapable of bending a new floor element inwardly at the top of the top connector which is in contact with the top connector edge of the previously positioned floor element so that inward bending can be accomplished by rotation about a center point that is the connecting plane surface In order to allow inward deflection when used in the prior art system, it is necessary to form a significant backlash that goes beyond what is acceptable for conventional floor elements where good quality is required. , aesthetic connections are a requirement, A 13a, ~. 1 to 4 are difficult to manufacture because it requires connection on a large surface on the outside of the tongue and tongue groove. This also makes it difficult for the lateral displacement in the closed position. The geometry of the joint makes the upward bending of the upper connector edge-free.

The main thing

First, the invention is based on the fact that using suitable manufacturing processes essentially by machining and using tools whose diameter significantly exceeds the thickness of the floor element, it is possible to bake the preferred shapes reasonably, with high precision wood, wood-based boards and plastic, and But the type of machining uses a certain distance from the plane of cheating and grafting. Thus, the shape of the ligation system can be reasonably manufactured by applying very narrow tolerances. Such an application allows a million / azonite to be applied at the expense of the other elements of the floor element and the fire system.

The second aspect of the invention is that mechanical requirements must be met by the mechanical bonding system. , .m optma á.odes.

This recognition makes it possible to satisfy them <'., as previously known, that is, a) by forming a binding agent, such as special angles, rays, backlash, free clips, and proportions of clal30 pounds between different parts of the system and today. <

its function and strength are maintained or even increased in some cases by manufacturing techniques, joining, material selection and long, as well as shorter side optimization, and a combination of these,

The fourth principle of the invention is to develop the manufacturing technology and the measurement technology of the annealing system and to design such critical parts as much as possible in the smallest parts that require very little tolerance and to create such that allow measurement and control under continuous production conditions.

1 : Γ The first preferred embodiment of the floor member is provided with a mechanical alignment system according to the invention and is mated with the aid of Figs. 21 a and fe. To facilitate the understanding of the invention, the adapter system is schematically depicted. We must emphasize the operation we can achieve in other designs

I, which are given below

21a, 21b. Figs. 15 to 15 are schematic views of the joint 15 which is between the longitudinal side portion 4a of the floor member t and the other edge portion 4b of the other floor element.

The upper sides of the floor elements are located in a substantially common HP plane, and the upper portions of the edge portions 4a, 4b are in contact with one another in a vertical VP contact plane, the mechanical locking system securing the floor panels 20 to each other in both the vertical direction of the oil and in the horizontal direction. perpendicular to the VP connection plane. However, when laying the floor in a row of adjacent floor elements, one of the floor elements Γ can be moved along the other floor element 03 in the direction 03 (see Fig. 3a) along the connecting portion of the VP, such a movement can be used, for example, to fix the floor element together to join them. that are on the same line

In order to assemble the two vertical edges perpendicular to the vertical plane VP and parallel to the horizontal plane of HP, the edges of the floor member are provided in a manner known per se by a notch 36 at one edge portion 4a of the floor member.

In the plane of the VP, and in addition, 33 languages are formed by the other edge portion 4b extending from the VP plane.

In this embodiment, the base member 1 has a core or a core of wood 30 that supports a wood surface 32 on its front plane and a balancing layer 34 on its backing. Floor 1 is square and second mechanical

There are 3816 interface systems on both sides of the parallel shortcuts. 8 b, this second judging system can be of the same design as the longitudinal laryngeal system, but the short-lived iliac system may be of various designs according to the invention or a prior art implantation system may be used.

In another example, the floor element may be a parquet type with a thickness of 15 mm, a length of 2.4 m, and a width of 0.2 m. However, the invention may also be applied to square or different size parquet.

The core 30 is made of plywood and narrow wood blocks of some kind of inexpensive wood. The surface 32 has a thickness of 3 to 4 mm and is a decorative hardwood and varnished. The back! 34 layers of 2 mm plywood. In some cases, it is advantageous to use different types of trees in different parts of the floor element to provide optimum properties in some parts of the floor element.

As mentioned above, the mechanical weaving system according to the invention consists of a groove portion 38 formed on a portion of the floor member 4a and a tongue 33 which is formed on the peripheral edge 4b of the base member.

The groove portion 33 is delimited by an upper lip 39 and a lower lip 40 and an undercut groove having an opening for measuring the 36 different portions of the upper lip 39 and the lower lip 40 of the different lip portions. FIG. The groove is formed in the core 30 and runs along the edge of the floor element. Above the tongue groove is an upper wind or contact surface 41 which extends upwardly to the HP plane. Inside the opening of the groove, an upper surface 43 is formed, which in this case is parallel to the HP surface plane. This contact flat surface 43 runs inwardly into an inclined wind surface 41 having an angle A relative to the HP horizontal plane. Inside the closing surface there is a top shell 46 which forms the upper boundary of the undercut groove 35 of the tongue groove. The groove groove also has a lower end 48 extending down to the lower lip 40. On the upper side of this lip, a support surface 50 is provided. At the lower end of the lower lip, a connecting surface 52 is formed, which in this case extends slightly beyond the plane of VP,

IS iv a

21, the tongue 30 is made and extends beyond the VP plane when this edge portion 4b is mechanically connected to the edge portion 4a of the adjacent horseshoe. The wind portion 4b also has a surface of an upper rim or top connector 61 extending downwardly along the VP plane up to the root of the tongue 38. On the upper side of the root of the tongue 38 is an upper support surface 84, which in this case extends up to an inclined end 85 of the closing element 8 towards the tip of the tongue. The closing surface 85 passes through a conductive surface 66 terminating on the upper surface 87 of the upwardly closing tab 8 of the tongue. After the upper surface 87 there is a hump portion which can serve as a leading edge 88. This stretches to the top 89 of the tongue. At the lower end of the tip 89, there is provided a further guide surface 70 extending downwardly to the lower edge of the tongue and a support surface 71, the support surface 71 being used to cooperate with the lower lip 50 of the lower lip when the two floor elements are mechamically connected to each other, its top sides are on the same HP plane and meet at the VP plane that is perpendicular to it. that the upper contact surfaces 41, 81 of the floor members come into contact with each other, the tongue has a lower flange surface 72 extending to the bottom.

In this embodiment, there are separate surfaces 43, 84 in the asa language which, when closed, engage each other in the lower lip and the lumbar surface 50, 71 in the tongue engages the closure D1 which is perpendicular to the HP surface. In another embodiment, which will be described below, each of the protrusions 45, 85 will act as a face-to-face closure with the HP surface and as a supporting surface. which moves against direction 02 which is perpendicular to the surface. A 21a, 2b. 1, the sealing surfaces 45, 85 and the surfaces 43, 84 interact as with the top support surface of the system.

As it is illuminated from the drawing, the tongue 38 extends beyond the VP connection plane and has an upwardly extending lattice 8 at its free end or 69 apex. The tongue also has a closing surface 65 which is configured to cooperate with the closing surface 45 of the groove portion 38 of the adjacent interceptor floor element when the two such floor elements are mechanically connected.

and lek, so that their front surface is arranged in the same HP plane and meets in the VP plane which is perpendicular to it.

As is apparent from FIG. 1, the tongue 38 has a surface portion 52 between the closing surface 51 and the plane VP. When the two floor elements are combined, the surface portion 52 comes into contact with the closure surface 45 of the closure element 8. In order to facilitate the insertion of the tongue into the alphabet, the inward trouser or hepafthesis, the tongue as described in Figures 21a, 21b. 1 to 3, there may be a conductive surface 88 between the surface 88 and the surface portion 57.

Also among the 89 peaks. The conductive surface 68 may serve as a guide portion, since it has a smaller slope to the plane of the surface than the closing surfaces 43, 51

The tongue 71 of the tongue in this embodiment is flush with the plane of the HP surface. The tongue has a conductive surface 70 between said Ιοί 8 flipper surface and the tongue 89,

According to the invention, the lower lip 40 has a support surface 50 which cooperates with the corresponding support surface 71 on the groove portion 38 at a distance from the end 48 of the undercut groove. When the two baling brushes are in contact with each other, surfaces 84 and 71 are provided with a surface 84 between the surfaces of the half lip 39, which is formed between the one and the contact. In this way, the floorboard and the HP plane are realized,

According to the invention, at least the air portion of the lower end of the undercut groove 48 appears parallel to the HP plane and is spaced further

VP is connected to a plane like tip or tip 88 of groove 38. With this design, manufacturing is greatly simplified, and the displacement of one of the floorboards relative to another floorboard is in contact.

Another important feature of the mechanical coupling system according to the invention is that all parts of the lower lip 40 attached to the core 30, from the point C where the HP plane and the VP plane intersect, are located outside an LP2 plane. This plane is further away from said point C than the LP1 closing plane parallel to the LP2 plane and tangent to the closing surfaces 48, 88 of the hron 38, and the tongue 38, where these closing ends 41 are more tilted to the HP Plane. This small slice is a submerged groove, as will be described in detail below with a cutting tool.

o ~ large, the floor panels are wide

Another important aspect of the present invention is that the tongues 38 and upper lips 38 and the lower lip 40 of the edge portions 4a, 4fe are designed to allow the two mechanically joined elements to be disassembled to bend one of the pad members upwardly from one another. pivot point, which is adjacent to the intersection line C of the HP surface socket and the VP connector so that this floor is rotated from the tiled groove of the other floor element

The 21 a "21 b. In such embodiments, such disassembly is possible by slight downward bending of the lower lip 40. In yet another more favorable embodiment, there is no downward inclination for the lower lip, the attachment and disassembly of the floor elements takes place without this,

21a, 21b. In the embodiments illustrated in Figs.

One such mode is to place the T-element on the substrate and move it toward the previously laid down floor element amíg until the narrow tip 69 of the tongue 38 fits into the opening of the groove. Thereafter, the floor element 1 'is bent upward so that the edge walls 41 and the surface 61 touch each other on both sides of the connecting plane VP, while maintaining this contact, the floor element is bent downwards so that it is rotated downward about the rotation pin C. The insertion takes place by sliding the guiding surface 66 of the tongue along the closing surface 45 of the upper lip 39, while at the same time the conductive surface 70 of the tongue 38 extends to the outer edge of the upper side of the lower lip 40, The opening system can then be opened so that the floor element is bent upward. rotating around the hinge pin C, which is adjacent to the contact surface mating line of the HP surface glue and VP.

The second method of sealing can be accomplished by moving the new floor element 4a with the edge groove on which the tongue groove is formed to move the tongue-lined edge 4b of the previously installed floor element. After this, the new floor element is rotated upwardly until the surfaces of the floor members 41, 61 are connected in the intersection plane of the contact plane,

1 után and then the floor element is moved down or bent so that, until the final closing position can be combined, one of the pads is moved in an upwardly bent position towards the other.

The third way of joining the floor elements in this embodiment of the floor elements according to the present invention is to move the new floor panel horizontally toward the previously laid floor element 1 so that it, together with the closing element 38 of the tongue 38 or upwardly, aligns it with the groove portion 36 , the lower elastic lower lip 40 is flexed slightly downwardly, so that it snaps into the undercut groove 35 of the tongue groove for the closure 8, in this case also the disassembly as above, i.e. upward

from them. That's stone

With regard to the squeezing, it can be said that the upper lip of the upper lip 39 can be bent upwards in a very small degree, so that all parts of the tongue 38 and the groove portion 36 are compressed in some degrees, which are in contact with each other during the snap. This makes it easy to apply the boot and optimize the yeast system.

In order to facilitate production, the inward bend, the plump and the nose;

and in order to minimize the wind in the closed position, all surfaces that do not participate in the tight fit of the upper connector edges, and to create vertical and horizontal joints so that they are not in contact with each other in a closed position and are preferably not closed during closing. and also during disassembly. This allows manufacturing without breaking fractures on the contact portions and

it also reduces friction during lateral displacement at the contact edge. Examples of surfaces or surfaces of the coupling system that are not connected to each other are, for example, sealed positions 46 to 67, 48 to 69, 50 to 70 and 52 to 72.

The connecting system of the preferred embodiment may consist of a number of combinations of materials. The upper lip 39 may be made of a rigid and hard surface 32 and a softer bottom portion which may be part of the core 36. The lower lip 4 © may be the same or the same upper softer core 30, and may comprise a lower soft layer 34 made of different wood. The three kinds of wood

-43th fiber direction may change. This can be used to create a connection system that exploits the properties of these materials. The closure therefore, according to the invention, is closer to the upper hard and rigid part, which thus provides a flexible and compressible bar, to a limited extent, when the snap function is formed on the softer lower and elastic portion. It should be emphasized that the tester can also be made as a homogeneous floor element, more specifically such a padloetembeh.

Figure 22 schematically illustrates the inward bending process or principle around point C (top connector edges) application of the invention se10 Figure 22 schematically illustrates how to mount an adapter system to render it inward bending along the top connection edges. In this inward bend, the parts of the coupling system in the practice or in the prior art practice follow a circle whose center C is close to the HP surface plane and

VP intersection line intersection. If there is a big backlash in all the elements of the connection system, or it is allowed, or if substantial deformation occurs, this is possible during inward bending, the tongue and groove can be formed in many different ways ·. On the one hand, if the coupling system must have coupling surfaces that prevent vertical and horizontal separation between any contact or support surfaces, and if the material is not deformable, the following principles must be applied to the adapter system:

The upper part of the coupling system shall be constructed as follows:

Cl8 is a circular arc with a center C at the top of the surfaces 41, 81 and in this preferred embodiment cuts a point of contact between the upper lip 38 and the upper portion of the tongue 38 at point P2. P2 <Between P3, P4 and R5, between the upper lip of lips 39 and the latches of the tongue 38, and the intersection P2 and the vertical plane VP

It is located between the CiS on the arc and where all other contact points from F2 to Pl-Ig between the upper lip 39 and the upper part of the tongue 38, and between the intersection P2 and the upper part of the tongue 38, are or are outside Cl 8 Circular, These conditions must be valid for all contact points. In the case of the PS contact point and the CÍA pear, all ~ 44 ™ other contact points between P1 and P5 are located outside the C A corrector, and in the case of the Pli contact point, all other contacts between the P1 and RS are at the Cl C arc;

The lower part of the connection system is built according to the following principles

The C2B arc is concentric with the arc A and intersects a point of contact in this preferred embodiment; 40 lower lip: and the lower part of the 33 language P? point. All other contact points lie between P7, P8 and P9, and between the lower lip 40 and the lower part of the tongue 38, and between the intersection of P7 and the plane C28, and all of F6, P? furthermore, the lower lip 40 and the lower portion of the tongue 38 are stone; and between the intersection of the intersection P7 and the outside of the tongue 33 is or is at the arc C2B. The same applies to the P8 contact point and the circular arc C16A vi16

2.0

The connecting system according to said preferred embodiment has good inward bending properties. Easy to combine with 43, 84 surfaces that can be parallel to the HP horizontal plane and provide excellent vertical closure.

23a. s Figures 2: 3b show that FIG. f Fig. 2b shows how the coupling system according to Figs. The floor element 1, with the upper side 2 of the prior art, is located downwardly on a sleeve bearing chain on a milling machine, which transmits the floor elements with extremely high precision to a plurality of milling tools, e.g.

in which the floor element is. In order to understand understanding with other figures, the floor surface of the floor element HP is shown in FIG. Figure 3 shows that TP1 is deflected against a horizontal plane of a conventional web, the comparison being shown above, the first tool in the case of a wedge. In this case, the tool operates with a tool angle 04 which is parallel to the horizontal plane. The axis of rotation R A1 is perpendicular to the HP plane. The blade is formed by means of a second tool, where the position TP2 and the tool are such that the undercut groove 35 can be formed without affecting the shape of the lower lip 40 in this case. 35 with the angle of the closing surface 45 in the undercut groove. This manufacturing process is talented because the LP1 closing plane is so far away from the connecting plane that the tool can be inserted into the previously formed tongue. "As a result, the thickness of the tool should not exceed the distance between the two LP1 and LP2. as shown in 21 a and 21 b. FIGS. This manufacturing process is a prior art technology and does not form part of the manufacturing process of the present invention as will be described in detail below.

Figures 24a, 24b show an embodiment not forming part of the invention. This embodiment is characterized in that the adapter system is fully configured in accordance with the inward helix principle as described above, above the upper connector, A 4. In this embodiment, the closing surfaces 85 and the lower support surfaces 50 71 are flat but have different shapes.

and C2 are two of which

iO tate at the top end of surfaces 41, 01 The smaller Cl arc Cl is tangent to the lower contact point which is closer to the vertical plane between the closing surfaces 45, 05 at the point P4 having a tangent angle TL1 corresponding to the LP1 closing plane. The closing surfaces 45, 05 have the same inclination as this angle. The larger arc 02 is tangent to the upper contact point between the support faces 00, 71 and is closer to the end 48 of the tongue groove at point P7 having an angle TL2. The inclination angle of the support surfaces 50, 71

All the contact points between the tongue 38 and the upper lip 39 that lie between the P4 and the vertical VP s satisfy the condition that the Cl is located inside or around the arc, while all contact and end ends are in the form of a vlfile. only the sealing surfaces 45, 85 - satisfy the condition that these are located outside or adjacent to the Cl ring Suitable conditions are satisfied for the self-adhesive surfaces between the lower lip 40 and the tongue 38. All points of contact between the tongue 38 and the lower lip 40 are located between the point P7 and the vertical plane VP, in which case only the lower support faces 80, 71 are located outside or adjacent to the circular arc C2, while all contact surfaces are located. a point located between the end of point P7 and the end of the tongue groove 48 inside or outside the arc C2.

In this embodiment, there is no point of contact between the end P7 and the end of the groove 48

The most characteristic feature of these pieces is that each contact surface is the point of contact P4 and the contact point VP in this case is point P5, and the end of the groove 48 is located inside or outside the circular arc C1, so there is no end of it. Ci circular. The same applies to P7 to point where each point of contact is point P7 between the vertical plane VP, in this case the point P8, and the end of the tongue groove 48, lies outside or inside the circular arc C2 and is thus not in the arc C2 . As is clear from FIG. Referring now to FIG. 1, the coupling system, when these conditions are complete, is designed so that the inward translation can take place with a gap substantially in the full angle of translation that ends with the floor being tightly closed. by tight fitting or by a pressure fit when they are in their final horizontal position. Thus, the invention allows the combination of inward and outward facing floor elements to be carried out without any resistance, and a high coupling quality. If the lower support faces 71, 50 are made at a slightly smaller angle, the coupling system can be formed by a coupling system with only two of the above-mentioned P4 points on the upper lip and the points of contact P7 on the lower part of the tongue are the groove portion 38 and the tongue 38 between the whole inwardly slanting process until the final closure is formed and throughout the upward bending until the pads are separated from each other by a slit or a line-like closure is a great advantage since the friction is small and the floor elements are low. it can easily be turned inwards or turned upside down without the system getting stuck or stuck together, which poses a risk of damage to system components. One pressurized joining is particularly important in the vertical direction for strength. If there is a certain play between the supporting surfaces, the floor elements will be slipped along the sealing surfaces when subjected to stinking, until the lower contact surfaces reach the point where they are tightly pressed and fit, so a backlash will be a contact gap and some results in a level difference between the upper contact edges. By way of example, in the case of tight closure or pressure fitting, a high strength can be achieved if the angle of the closing surfaces is approx. 4 ° ° to the HP plane and if the lower support surface angle is about 15 ° to the HP surface

24a. Fig. 1A shows the closing angle A of the LP1 closing plane relative to the horizontal plane HP which is approx. 39 °, while the TL2 supporting plane is provided along the line 5, 71 with a VM support angle of 4Ms, the hair gap is LP 1 and

Between TL2 planes 25 The closing angle: and the large difference between the angle of support and the high closing angle should be sought, as a result of high horizontal closing forces. The closure surfaces and the wood surface superficials are curved, the steps may be of various angles, etc. but this is a manufacturing ne10 below

it may be complementary to head restraints or different top support surfaces

Even when the lock surfaces and the; the contact points of the supporting surfaces differ to some extent from these principles, they may lean inwardly at their upper contact edges, if the connection system case is adjusted, its contact points or surfaces are small relative to the thickness of the floor, and the properties of the floor element material are pressure, the elongation and the elongation. the drive is maximally used so that there is a very small backlash between the connecting surfaces. This can be used to increase the closing angle and angle difference between the closing angle and the support angle.

Thus, the inward curl sublayer shows that the critical portions are the 45, SS sealing surfaces and the lower Sö, 71 support surfaces. It also shows that the degree of freedom is relatively high with respect to the formation of the other parts, such as forming the upper surface 43, 64, and forming the guide element 44 of the closing groove, and the upper surface 67 of the sealing element 8 and the conductive surface SS of the groove, and the groove portion 33 48, 49 for forming the lower lip, the closing surface and guiding of the lower lip 51, and the flange surfaces 89, 70, 72 of the tongue. These should be different, the mountain should be two

The circular shape of Cl, C2, and all parts except the surfaces 43, 84 must be free spaces so that these parts do not come into contact with each other during inward bending and upward bending. Also, these parts can be formed without the need for stricter fracture requirements and lead to safe inward and upward bending and also less friction for minor friction related to lateral displacement of the connected elements along the contact plane VP (D3 direction). means that these parts of the connection do not have any functional properties or roles to prevent vertical or horizontal displacement, as well as displacement of the contact rim in the closed position. Thus, loose wood fibers and small deformable joints; with free surfaces The bending around the upper contact edges, as mentioned above, becomes the case when the adapter system is configured to provide a small \ t

between the sealed surfaces 45, 55, the closing edges of the slats are clamped together. In addition, the backlash also includes lateral displacement in the closed position, reduces the passage and increases the degree of freedom in production, allowing for displacement with closing surfaces that have an angle of pitch as they lead to the flange of the LPf and upper contact flanges. The backlash is significantly less contact

delem over the top of the table, as if it were a backlash between the supporting surfaces, before 20, thanks to this game, it will also be smaller due to the fact that slipping in a tensioned position is reflected in a smaller support angle, i.e. at a much smaller angle than the closing angle. . This minimal backlash, if any, can be very small between the closing surfaces, for example, only 0.01 mm. In the normal connected position, the backlash is practically 0, the connecting system can be a case where the backlash only occurs when the contact edges of the floor elements are pressed with maximum force. It has been found that approx. Extremely good bonding qualities of a backlash greater than 0.05 mm, due to the contact gap found and located in the HP surface plane, which is hardly noticeable in a fully extended load or in this position.

At the same time, we need to pull out that the connection system can be formed without backlash between the closing surfaces

A. Material pressure and backlash between the sealing surfaces, and the bending of the connecting parts on the sealing surfaces in an easy-to-measure manner

49 ", such that the annealing system is subjected to a tensile load, and on the upper surfaces 41, S1, the contact gap is measured at a predetermined load that is less than the strength of the coupling system, tensile beam. The tensile strength is the strength at which the coupling § system does not break or break. Appropriate firming strength is about 50% of the tear strength. For example, it may be mentioned that the strength of the long side bond exceeds 3 kg per millimeter. Shorter side weathering can be even more robust. A floor with a suitable coupling system according to the invention can withstand a load of 1000 kg per meter of connection. A high-quality connection system> at the top 41, for ski surfaces, Ö, 1 to 0.2 mm, if you are a specialist!

is exposed to tensile stress or stress, A connection

slack decreases when the load ceases. By varying the tensile stress, the relationship between structural backlash and material deformation can be determined. In the case of a smaller tension, the connection gap is substantially about the extent of the structural gap. If the load is retained, the gap increases, which is due to material deformation. The coupling system may be provided with a built-in initial tension, i.e. a tension, and the sealing surfaces and the supporting surfaces are communicated by an interface pressure such that the aforementioned connection gap is not visible to the aforesaid. load.

The geometry of the coupling system and the backlash combined with the sealing surfaces can be measured by pressure from the material quality around the surfaces 41.81 by dropping the connection in a direction perpendicular to the connecting edge. Since the connection system is made by linear machining, we get the same profile, but with the entire connection wind. The only exception is the manufacturing tolerance, which can be manifested in the absence of parallelism due to the fact that the flooring may have been turned or moved vertically or horizontally, as it has passed through the various cutting tools in the machining machine. The sample from two connecting edges gives a very reliable picture of what the connecting system looks like. After we have cleared the specimens and cleaned them from loose fibers by seeing a sharp connection profile, these can be examined for connection geometry, and for material pressure and deflection. The two parts 30 • 50 ve can be compressed, for example, by a force that does not damage the adapter system. , first, the surfaces 41, 81, the backlash between the closing surfaces and the geometry of the coupling are then measurable with a measuring microscope of approx. 8.01 mm or less depending on the equipment. If stable and modern machines are used during manufacture, kh is satisfactory if the profile is tested in two smaller ranges of the floor element to determine the average play back and binding geometry, and so on.

All measurements must be made when the floor elements are exposed to a relative humidity of about 45%.

Also in this case, the closure member or the tongue upwardly closing element 8 has a conductive surface 68, the leading part of the closure comprises portions having a slope less than the inclination of the closing surface and in this case the inclination of the angle TL1, the tool is appropriate the inclination which forms the closing surface 45 TA2, which in this embodiment is equal to the angle TL1,

There is also a guide member 44 on the surface of the tongue groove 48 which cooperates with the conductive surface 88 of the tongue during inward bending. This guide member 44 also includes portions with a slope less than the inclination of the closing surface.

In the lower part of the lower lip 40, there is a rounded sealing surface 51 which cooperates with a radius formed at the lower part of the tongue, which is in contact with the lower support surface 71 at the PT point and the inward bending.

The lower lip 40 may be flexible. The inward pressure h can be applied to the junctions between the tongue 33 and the lower portions of the lips 48 as the lower portions of the salt lip. This is the pressure in the case of pressure on the sealing surfaces, since the lower lip 48 has a significantly better elasticity than the upper lip 39 and the tongue 38. With the inward and upward bending, the lip is inclined downwards, the flexural capacity is only 8.1 mm or slightly more with compression force from the material quality and for small contact surfaces, for example, the lower 50, 71 the shape of the supporting surfaces changes so that they may have a slope less than the angle TL2. while inward bending can be performed easily. A flexible lip can be combined with a relatively large closing angle. If the closing angle is small, one

Both the SS tower section and the tongue 38 are provided with guide tongues 42, 51 and 88, 70 which introduce the tongue into the groove and facilitate snap and inward bending.

Figure 25 shows embodiments that do not form part of the invention, wherein the lower lip 40 is shorter than the upper lip 39 and is spaced from the vertical VP plane at a distance. This has the advantage of allowing greater design freedom for the 45 sealing surface; large tool with TA angle, while relatively large tools can be used. In order to facilitate the squeezing by bending downwardly the lower lip 40, the groove portion 38 is formed deeper than would be necessary for the space required to move the tip of the tongue 38. The wind marked with the 4b dot line shows how the system interacts with each other in the inward curve with the upper contact wind, while the dotted line 4b shows how the parts of the system relate to tensioning the tongue into the tongue groove 4b. in a straight line in the direction of the seat 4a.

Figure 28 shows a further variation of the above-mentioned principle which is not part of the invention. Here, the coupling system is provided with sealing surfaces which are 9tF in relation to the HP surface plane and which are substantially larger than the angle TL1. However, in such a preferred embodiment, however, the anchoring system can be opened to bend up the closing surfaces which are extremely small and the connection is essentially a line-like contact. If the core is tough, such an anchoring system will provide very high strength, the closure design and the sealing surfaces will allow the squeezing of the extremely low downward sloping lip, as indicated by the dashed line in the figure.

The 27a, - ~ c. Figs. procedure. To make this description more comprehensible to one of the floor elements, it is referred to as a groove and the other; affair as my heart. In practice, the floorboards are down to the point where the tongue is connected to the other.

Nose. A talented laying procedure is placed on the substrate, either along two or three sides of the shank, at the body line. The groove 39 is placed with the upper lip 39 so that the upper lip 39 is placed above the outside of the tongue 38, the top contact disks being in contact. make each other. Subsequently, the groove element is turned towards the substrate while pressing the tongue of the tongue outlet until the final seal is formed: FIG. as shown in FIG.

The sides of the floor sometimes have a certain degree of deflection. The groove10 is then pressed down or slid down until the portions of the upper lip 39 come into contact with certain portions of the tongues 8 or upward portions of the tongue, and the lower lip 48 is not in contact. the lower part of the tongue. In this way, the page can be straightened and then the batteries are final

The 27a. - c. Figures 1 to 4 illustrate a method not forming part of the invention, such that the bending to the insert occurs in a gap or through a contact between the upper part of the tongue and the tongue, or between the tongue and the lower and upper portions of the tongue groove;

In-line bending in this embodiment is seen at points F4, P7. Inward bending can be easily accomplished without encountering significant resistance and ending with extremely tight closure, closing the padlocks in their final position, resulting in extremely high quality vertical and horizontal closure.

2S In summary, the downward bending can take place in practice as follows. then on both edges. When the upper connector edges 0 close together or come into contact with each other along the length of the entire member, and the element is held at a certain angle to the substrate, the final downward bending may occur.

When the batteries are already assembled, they can be disassembled in the closed position in the direction of the closure, i.e. in parallel with the connecting safe

ink-jet connection. When the elements are moved horizontally towards each other, the tongue is inserted into the groove. Under the subsequent continuous pressure, the lower lip 40 bends and the closure 8 engages in the closing groove or undercut 35. It should be emphasized that the basic feature of the preferred connection system is the penetration, where the lower is flexible. Of course, the coupling system must be bent, the najhtass cap and the depth of the turret portion, and the height of the closure 8 and the thickness of the lower lip 48 must be appropriate and dimensioned so that the engagement can be performed. The basic principle of the coupling system according to the invention is that it can be used much more advantageously of materials which are less flexible and flexible and this becomes evident from the following description and Fig. 34.

The described investment techniques can all be performed along the four sides and combined with each other. When one side is laid, a lateral displacement is generally carried out in a closed position.

In some cases, for example, when the shorter side is first bent inward, a: the upward bending of the two elements usually occurs.

A 3Ö Figure 1 shows a first etem, an upwardly bent second element 2a, and an upwardly bent new third floor element 2b, which is already connected to the second floor element 2b along the side of the short sleeve. After the new flooring 2b has been laterally shifted upwardly along the shorter side of the second element 2a and in the closed position on the lateral side, the two flooring bristles 2a, 2b are bent downwardly together and closed along the longer side of the first member. wishes the new floor panel 2b to be inserted with its tongue into the tongue groove when the beam is slid in parallel with the second element 2a and when the second element 2a is at least partially inserted into the tongue groove and when the upper connecting edge is in contact: the floor element 1 top contact edge. In FIG <Figure shows that the interconnection system is that

54 can be set up with such a language groove design, tongue: and closure means that it is possible.

All laying procedures require ethos in closed position. One exception is lateral; In case of offset, in a closed position, a number of elements are connected along shorter sides and then a whole row is laid simultaneously. However, this is not a reasonable investment procedure.

c is a combined bait, not part of the invention 31a, 31b, al. an undercut element formed. The groove portion 35 and the groove 38 may be formed according to one of the embodiments described above. The lower part of the groove element is provided with a known 6 having an attachment element 8b and a sealing surface. There are 35 grooves in the scallop, one

In accordance with a known embodiment. In this embodiment, the element 8b operates with a relatively large upper part 9, such as an extra guide in the first portion of upward or inward bending, and significantly facilitates this first phase of inward bending when positioning occurs and any banana is shaped. pay. The connecting element 8b results in automatic positioning and compression of the pads until the leading portion of the tongue comes into contact with the undercut groove 35 and the final closure is not real. Layout is much easier, and joining will be very powerful with the collaboration of the two driver systems. This connection is very suitable for connecting large floors especially in public areas. In the example shown, the tape 8 is attached to the groove groove but could be connected to the tongue plate. The positioning of the tape 5 is thus arbitrary. Additionally, the connection can be both snap-locked and folded up and moved laterally in a closed position.

Of course, the connection may also be applied in different variations on the long and shorter sides, and may be advantageously combined with other buckling variants described herein and with other known systems.

A convenient combination is a snap system on the short solution without an atomic band. This may in some cases make production easier. A tape that is fixed after manufacture also has the advantage that the entire ~ 55 ~ lower lip or part thereof can be formed. This is an extremely large design, the use of cutting tools for the use of cutting tools, that the upper lip 39 and the sealing surfaces formed have a high closing angle.

can also be made and strip can be produced with arbitrary 8 strips that do not stand out from the top 33

for.

as can be seen in the embodiment shown in Figure 50, the belt should not be continuous. Alternatively, it should be continuous along the entire length of the bond, but may consist of a number of small portions interlaced with the long side and the short side.

The coupling element Sh and the undercut groove 35 thereof can be formed with different angles, heights and radii, which can be chosen arbitrarily in order to either prevent separation and / or to facilitate inward deflection or penetration.

32a, - d. Figures 4 and 4 show how to implement inward translation. The wide band 8 allows the tongue 38 to be easily applied to the tape at the onset of inward acidification. The tongue is then automatically slid into the groove portion 38 parallel to the bend. The appropriate lay-out can be done by inserting the tape under my tongue. All of the braking functions described above can be used for this preferred combination system of flooring elements. Figure 33 and 34, which do not form part of the invention, describe and illustrate a manufacturing-specific and optimized coupling system for a floor member having a core of wood. It made. Figure 33 shows how to build the longer page. In this case, the connection system is optimized primarily for inward translation, upside down and low material density. Figure 34 shows how to create a shorter page. In this case, the coupling system is optimized for snap and high strength. The differences are as follows. The closing element of the tongue 38 and the shorter connecting element 5a are longer, measured in a horizontal plane. This results in a higher tensile stress for the 8 closures. The groove portion 38 is deeper on the roofing element 5b, which facilitates lowering of the lower lip downwardly. The closing member 8 is on the connecting element 5 which reduces the flap of the lower lip downward on the incision. The sealing surfaces 45, 85 have a larger closing fabric and a smaller angle for the lower contact surfaces. The leading portions of the edge portions 4a, 4b on the closure and the closing grooves are larger for optimum driving, while at the same time the contact surfaces between the sealing surfaces are smaller, as the strength requirements are lower than for the flattened side. The connecting system on the longer and shorter sides may be different or have different properties of materials in the upper lip, which can be adjusted so that

in the lower lip and tongue, and these lead to optimization of the different properties towards it, which are required at least by the function and Figure 35 of the invention, which is not part of the invention and the SZÍlárusay invention. both long and short. Here, only those parts that have not been previously described in greater detail are described.

The sealing surfaces 45, 55 have HLA angles greater than ILI

This results in a higher horizontal closing force. In addition, this flexion is a matter for the core wood as well as the elastic rigidity3

sag from the front so that inward and upward translation can take place. The contact surfaces of the sealing surfaces must have a minimum of 25 and must be adjusted to suit the core strengths.

As soon as the patches are attached, a small portion is preferably smaller than that of the locking element in the vertical direction, forming the contact surfaces of the closure 8, and the contact surfaces of the sealing groove 14. Partially rounded and oblique conductive surfaces that are not in contact with each other in closed internal and inward as well as upward bending.

It is to be understood that extremely small contact surfaces in relation to the floor thickness T between the sealing surfaces 45, 85, for example, result in a few closing times of 0.1 mm, and that this closing force can be affected.

the tensile strength of the closing element in a horizontal plane (i.e., the HF surface plane). This can be used to create closing surfaces that have an angle

In this case, the closing surfaces 45, 85 are planar and parallel. In this aspect, the closure surface 31 of the closing groove is advantageous.

pushing the tool parallel to the sealing surface 45, this does not affect the vertical distance which is directed towards the contact side of the VP: it is easier to achieve a high quality connection quality. Of course, small deviations from the plane are the same, and they have an equivalent effect. Accordingly, the lower Sö support flap and the lower support beam 71 are made, and the VLA 2 angle, which is j such as P? tangent line of the tongue drawn to the point T, which is located on the support surface 71 closest to the lower part of the tongue groove. As a result, inward translation can be accomplished with a certain gap during the entire angular displacement. The support surfaces 50, 71 are also relatively small in relation to the floor thickness T. These support surfaces may also be substantially planar. The flat support surfaces facilitate the implementation of the principles described above.

The support surfaces 50, 71 may also be made of hair 20 smaller than the tangent tilt of TL2. This can be achieved by partially compressing the material to some extent and by lowering the lower lip 40. If the support brackets 50, 71 are small relative to the floor thickness T, the possibility of the surfaces being covered

more or less than TL1 and Tt 25 are larger.

Fig. 30, which is not part of the invention, is a base element. An upward bending of the element 11 is shown, the floor of which is formed by a geometrical configuration, and whose closing surfaces are thus shaped like a tangent TL1 and are inclined as tangent to TL2, rnig ug is relatively small. The inward translation and the overlapping points P4 and P7 are very small. Point P4 can bend it

the lips are the figs which are compressed at the upper contact areas and at the points F4, K3, K4, while at the same time in the upward direction the point P4 in the direction opposite to the direction of the lower lip nt, the lip 83 and the tongue 38 can be folded downwardly downward by P ? contact

The upper surfaces 43, 64 are preferably perpendicular to the contact plane VP.

Production can be made considerably easier if the top and bottom support surfaces are flat and preferably horizontal.

again not part of the invention; Referring to FIG. For example, the rocker C1 shows that the upper support surface can be formed in different ways inside the circular arc Cl without affecting the angular decision and the feepfflastic effect. In the same way, the circular arc C2 shows that the inner portions of the tongue groove and the outer portions of the tongue can be formed in a number of different ways based on the atheists, without being angled and bent. would be affected.

The entire lip of the upper lip 39 is thicker than the lower lip 40. In addition, it is advantageous for parquet floors, which, as a result, can create a counter surface.

The areas 31 to SS where the contact surfaces are facing, the connection surfaces on both sides must be in contact with each other to make at least one

20; In the interconnected position, but preferably during the inward translation, the relationship between the tongue and the tongue groove in these S1-SS domains only partially results in improved closure in the Öl Direction and hardly contributes to the closure wa D2 writes the inward curl and side-sliding and unnecessary deflection ~ 2S during manufacturing, and even increases the risk of creaking and unpleasant effects, as floor surfaces

The TA weave, as shown in FIG. Figure 4 shows the TA4 of the 3S subframe groove 44 and the same! it operates at an angle as the angle of the closing surface, and a portion of this tool, which is located within the vertical plane in the direction of the tongue groove, perpendicular to the tool mill TA marked with its TT. Part TA of the tool and the width of the TT partially determine the shape of the surface 52 of the lower lip 40

Numerous angles and ratios are extremely important for optimal manufacturing, operation, cost and strength.

The size of the connecting surfaces is minimized. This reduces friction and facilitates displacement or displacement in the closed position, as well as bending upwards and downwards and woods and decreasing swelling and squeaking.

the adventurous fortune10

It is also possible to slap it. In a preferred embodiment, the surface portions of the tongue 38 are less than 30% of the size of the contact portions of the groove 38, the contact surfaces of the closure surfaces 85, 45 in this embodiment represent only 2% of the thickness of the floor T and the lower supporting surfaces of the base. only 10% of floor thickness. As mentioned above, the coupling system in this embodiment has a plurality of Ski-SS portions that form free surfaces. In order to avoid contact with each other, the space between these free surfaces and the other elements of the coupling system within the scope of the invention may be filled with adhesive, insulating material, impregnating agent of different kind, lubricant and the like. On free surfaces, here are the surfaces in the coupling system obtained by machining with a suitable cutting tool.

If the connection or contact is tight: fitting, the closure surfaces 85, 45 may prevent horizontal separation even if their HLA angle is greater than that of the HP horizontal plane. <However, the tensile strength of the coupling system is greatly increased if this closing angle becomes larger and the angular difference between the closing surfaces 45, 65 is lower and the lower Sö : , 71 is a support angle between the VLA2 fitting angle and this angle is smaller. If there is no need for high strength, a low angle and low angular deviations can be formed above the closure relative to the lower fitting.

for floating floors, HLA z can be achieved by, for example, 30 *. In the preferred embodiment shown in Fig. 35, the closing angle is 5O '; and the angle of the supporting surfaces 20 *. As we have already seen in the description of an earlier embodiment, the angled pick-up system can be constructed as?

are designed to create a very high quality connection system with closing angles between 40 and 55 'and support angles between Q and 25'. We must emphasize, however, that other ratios can result in satisfactory operation.

The horizontal extension of the tongue PA also extends 1/3 of the thickness of the floor member T, and is preferably about 1/3. It should be around 0.5 * T. This closure 5 is required for a strong outlet, which is provided with a guide portion, which must be formed of a suitable material that is accessible, achievable in the upper lip 39 between the closing surface 85 and the vertical VP.

The horizontal extension PA of the language 33 can be divided into two substantially equal parts of FAI and PA2, where the FAI forms the closing element and the larger PA2 can form the surface 54. The horizontal extension PA1 of the closure 8 must not be less than 2 times the thickness of the floor. The surface 84 should not be a large bowl, above all along the longer side of the floor element. Otherwise, the friction associated with lateral displacement will be too high. In order to make rational production feasible, the depth of the tongue groove is G

37a. - c. Figs. In particular, this embodiment shows that the attachment system on the shorter side may consist of different materials, or different tree types 38b, 3ee, and may differ from the core 30 of the long side. For example, the shorter portions of the 38 sides of the shorter sides may be made of harder and more elastic wood, such as the 38 tongue, which may be hard and rigid, and may have additional properties, or are different from its length. On the shorter side of the groove portion 38

they have a layered core, wherein the top and bottom sides are made of different wood species and the core consists of blocks that are glued together. This design offers great variation in material bundling with its most suitable functional strength and production pouch; create.

It is also doubtful that the variation of the materials along the length of one of the sides, such as those arranged between the two shorter sides of different wood or material, may be selected so that some of them can be selected on the basis of their respective properties, which improves the body structure. strength, etc. Various properties can be achieved with different strands of long and short solutions, and plastics can also be used on the shorter side and, for example, on different parts of the length side.

these are layers that can be formed so that the upper lip, tongue and lower lip can be formed on both sides of the longitudinal and shorter sides, having different material composition and fiber direction; which provides different properties in terms of strength, flexibility and machining capacity.

The invention does not include 38a, d. 1 to 3 illustrate a manufacturing process according to the invention. In the case of the illustrated embodiments, the production and machining of the contact wind and the machining of the tongue groove take place in four steps. The tool diameter of the tools used exceeds the thickness of the floor. The tools serve to create a shaft groove with a large closing angle in a tongue groove with a lower lip extending beyond the mesh.

In order to simplify the understanding and comparison with the above-described coupling systems, the edges of the floor panels are illustrated by the upward-facing floor. Normally, however, the floor elements are arranged face down during machining. The first IFI tool is a roughing tool that works at an angle TA1 relative to the horizontal plane. The second TP2 tool is formed horizontally by the hammock and the upper and lower support arms. The third TA3 tool can operate substantially vertically, but at an angle, or at an angle and the upper edge edge.

The critical tool is the TP4 tool, which forms the outer part of the closing groove and its closing surface. TA4 is for ΤΆ shown in Figure 35. As is apparent from Fig. 38d, this tool only removes a minimal amount of material and essentially forms a sealing surface at a large angle. .Therefore, the tool should not be spaced with a wide section that extends beyond the vertical plane. Furthermore, the amount of removable material should be as little as possible to reduce wear and wear of the tool. This is accomplished by forming a crimping tool for the roughing TP1 and selecting a suitable angle, such that the machining process requires, in particular, at least two machining cutting tools that work at two different angles to form a bottomed undercut groove 35 in the upper portion of the groove portion 38. The language groove with even more tools It is also possible to use tools in different order20

The purpose of the description is further to detail the method of forming a groove portion 38 in a floor element having a top side 2 in an HP surface plane, and an edge portion 4a having a plane of VP that is perpendicular to its upper side. 4a starts at the edge and defines two lower lip 39, 40, each having a free outer edge.

on one lip, the tongue groove has 35 undercut grooves forming a closing surface 45 and further away from the VP connector plane than the surface 52 of the other lip. According to the method, the machining is carried out by means of a plurality of rotary cutting tools having a diameter greater than the thickness T of the element. On the beer of the process, the coaxial tools and the floor element are forced to move relative to one another, which is parallel to the connecting edge of the floor element. The process is highly characterized by the formation of a undercut by means of at least two such cutting tools, the axis of rotation of which is at different angles to the upper side of the floor element 2: furthermore, a first tool is driven from these tools in order to form parts of the batten; that are farther from the VP connector plane than the. and (3) a second tool is driven from the tools to form the closing surface 45 of the undercut. The first of the tools is rotated about a rotation axis having a greater angle to the upper side of the floor element 2 than said second tool. The lower lip 40 may be configured to protrude beyond the VP connection plane. The lower lip 40 may be configured to extend beyond the VP connection plane. Alternatively, the lower lip 40 may be configured to be blzo1Ö from the VP connector plane, driven by a preferred embodiment, to a certain angle of up to 85 ° relative to the HP surface plane, the second tool being rotated on its axis of rotation in a preferred embodiment.

adjust the angle to the HP surface plane, and place the tools on the floor element15 in such a way that the order depends on the angle of their rotational axis and the surface of the HP surface plane, so that the rotation axis rotating at a greater angle before mahkálía it. before the smaller angle tool.

In addition, we use a tool to form the first eo with the ioel

36 lower parts of the groove section. This third tool contacts the second tool. The third tool is set to close at about 9 ° with the HP surface plane 3, the first tool can be folded so that the wider surface portion of the edge portion 4a of the floor element is machined than the second tool. forming a surface facing the surface of the HP surface, such that the tip of the tool profile thickness is smaller when viewed parallel to the axis within the radially outer portions of the tool. Furthermore, the

From among the tools, the rack is operated so that they are in different settings to form the undercut parts of the tongue groove. The tools can be used to work with wood or wood-based pressed plates.

Fig. 38, which is not part of the present invention, shows how a coupling system can be formed to increase compensation for swelling. As the relative humidity increases when the weather turns to hot, the surface 32 swells and the 4o has no elasticity, windbreak divides 61 surfaces to break it. This problem can be solved by designing the connecting system bed to realize the isolation. and in combination, <* Ji

The driver system can be configured. be a game when the connecting edges are compressed horizontally along the line, for example under the conditions of manufacture and normal A few hundred mm backlash leads to the solution or reduction of the problem, a negative backlash, that is, the initial tension can lead to the opposite effect

If the contact surface between the sealing surfaces 45, 65 is small, the adapter system may be configured so that the closing surfaces are even more compressed than the upper surfaces 41, 61. The closure 8 may be formed with a groove 64a between the closing surface and the upper horizontal surface 64, with the proper design of the tongue 38 and the closure 8, the tongue 69 of the tongue may be bent outwardly to the end of the tongue groove 48 and thereby act as an elastic member for swelling and shrinkage. surface layers.

In this embodiment, the lower support surfaces of the coupling system are parallel to the horizontal plane for maximum vertical closure. However, it is also possible to achieve an expansion capability using a compressible material, for example, between two sealing surfaces 45, 85 or compressible material as the material of the tongue or groove portion.

Figure 40 illustrates a coupling system according to the invention, which has been optimized for high torsional stiffness 38 '. In this case, the outer part of the tongue is in contact with the inner part of the tongue groove, If this switching surface is small and if the contact is formed without a very high compression, the movable closed position of the coupling system

Fig. 41 shows a coupling system with the lower surfaces 5, 71 having two angles. Parts of support surfaces outside the contact plane are parallel to the horizontal plane. Within their contact plane closest to the inner part of the tongue groove, their angles correspond to the tangent of the surface 32, which is the innermost pe30 of the interconnected support surfaces.

The invention is not part of the 42a. and 42b. Figs. 4 and 5 show a connecting system for closing the short side of the floor elements and having a high tensile strength even in the case of softer materials, since the closure 8 has a large horizontal nylon-absorbing front face. The tongue 38 has a lower portion which extends beyond / out of the circular arc C2 and thus does not follow the inward bend as described above in the ih of 42h. 1 to 3, the torso system is folded upwardly about the upper contact edge, since the closure element of the flap 38, after this first upward bending has taken place, leaves the tongue flush with horizontal deflection. The above-described principles of inward translation and upward h

around the upper connecting edges This is to facilitate the upward translation as long as the connecting system safe does not engage in various other ways, for example, to pull or flip, or even simultaneously, both of the lower lip 40 bending.

The invention does not include 43a. - ~ p. Figures 1 to 4 illustrate the principle of how the lower part of the tongue can be formed relative to the lower lip 40 to facilitate horizontal snap-on in accordance with the invention in a coupling system in which the locking grooves are placed in rigid upper lip lip 39 and have a flexible lower lip 40 . In this embodiment, the upper lip 39 is substantially more rigid, inter alia due to the fact that it may be thicker or harder and even more rigid.

six, the lower lip 40 may be vexonyaoo and softer, and the basic bending of the oepae is therefore performed on the lower lip 40. The snap can be made much easier by, among other things, the maximum bending of the lower lip 49, which limits the bending so much. as much as possible. THE

Figure 43a shows that the lower lip of the lower lip 40 increases with a maximum

To a bending Β1 level determined by the tongue 36, which is inserted into the harrow portion 36 so that the rounded guide portions are in contact with each other. When the flap portion 36 is inserted even more, the front slit 49 bends backward until the head is inserted into the final hatch.

and in the sluice of the closure 8 in the undercut groove 35. The front portion 46 of the tongue 33 may be configured such that the lower lip 40 does not face downwards, which is instead pushed downwardly by the support surface 59. This front portion 49 of the tongue must be of a shape that either touches or extends from the maximum bending level of the lower lip 40 when this lower lip 49 bends from the exterior of the support surface 59 of the tongue 68. If the shape of the tongue 88, which in this position overlaps the lower lip 40, which is dotted with line 49b, the strap 82 is shown in FIG. can be significantly larger as shown in FIG. This

surli system he slap may cause the bepanmtasnaí and knitting destruction you take from 43o. Figure 1 shows that the maximum curl can be delineated with the 15 grooves and the 38 languages if we create a case. that there are 84 spaces between the lower lip 48 and the front 49 of the tongue,

The horizontal engagement after the long side closure can be interpreted in relation to the engagement of the shorter side. When the long side is punctured, it is possible for the connector according to the invention to be pressed or flush with a floor panel that is tilted upwards. This upward-facing snap position is shown in Figure 44. The lower lip 49 requires only a very small bend of 83 to allow the conductive surface 68 of the closure member to come into contact with the guide element 44 of the closure groove, so that the closure then fits into the groove 35 of the underlayer by bending downwards.

Figures 45 to 50, which do not form part of the invention, illustrate various variations of the invention that can be used along the vane and the shorter side and can be formed with large cutting tools. Using modern manufacturing techniques, it is possible to create complicated materials according to the invention by machining in the material of the floor elements at a low cost. It should be noted that the geometrical designs shown can, of course, also be formed, for example, by means of chilling in the embodiments shown in this and the figures already described. but this process is generally much more costly than machining and inappropriate for the airborne floor material, which is generally used on floors.

45a, 45b. 1 to 3 illustrate an embodiment of the invention, wherein the tongue portion of the tongue 38 is curved. This flexibility is available. that the tip of the tongue is filled. The bepaitesti seren, the lower lip 40 bends downwards and the lower lower part of the tongue 38 is inclined upward.

48a. and 48b, the invention illustrates a connector system having a split tongue. The two parts of the tongue lean toward each other while the two lips are inclined in different directions.

These two coupling systems allow you to bounce up and down and in and out of assembly and disassembly.

47a. and 47b. Figures 4a and 6b show a combined joint, wherein a separate portion 40b forms the protruding portion of the lower lip and where this part can be flexible, the coupling system is inclined. The lower lip, which forms a part of the core, is designed with its retractor in such a manner that the snap blade is carried out without the lip being driven or bent. Only the elongated discrete part, which can be made of aluminum sheet, is flexible. The coupling system can be designed so that both parts of the lip are flexible.

Figs. 48a and 48b show the jointing of a combined bond, the lower lip consisting of two parts, and wherein the sole form is the supporting surface. For example, this connecting system can be used along shorter sides together with some other coupling systems according to the invention. An advantage of this coupling system is, for example, that the underside groove 35 can be formed with a high degree of freedom in a rational manner and large cutting tools can be used to form it. After machining, part 40b is connected and its shape does not affect the workability of the workpiece. Part 40b is flexible and there is no closing element in this embodiment. A further advantage is that the coupling system makes it possible to connect extremely thin core materials since the lower lip can be made very thin. For example, the core material may be a thin compact plywood, and the top and bottom layers may be relatively thicker, such as a cork or soft material layer, which provides a soft and absorbent floor. By using this technology, it is possible to combine core materials with

Iw which increase. Can be applied to Myilaeyags as well

Figures 49 and 50 show two combined bond variations, which can be used with a combination of additional preferred systems. Fig. 49 is a combination binding of the collectors in an embodiment in which the strip forms a protruding elastic portion and the operation of the system is similar to that shown in Fig. 45, Fig. 50 shows the combined joint 10b which can be formed by the connecting element 8b. 40b, which is disposed within the connection plane.

Figures 51a, f, which are not part of the invention, may be used to connect the laying process to an operating theater according to the invention: which is the case of the paddle to be horizontal coupling, upward bending,

IS is used in combination in an upwardly biased position and in a downwardly bent position. This method of laying can be used for flooring elements according to the invention, but can also be used for arbitrary mechanical joining systems for floors that have properties that allow this laying process to be used. In order to simplify the description, the laying process will be called a single floor element mutation and combined with another floor element, which is called2k. Floor brushes are the same in practice. Nyiivánva-

which can be slotted in the same order as the tongue d in the same way.

edge 4a with tongue, and edge portion 4b with groove portion 38 are laid in the starting position 51a. as shown in the figure. The tongue 38 and the groove portion 38 have closing means that exhibit vertical and horizontal variations. Consequently, the edge portion 4b is displaced horizontally in the FI direction relative to the edge portion 4a until the tongue 38 is in contact with the groove portion 36 and the lower and upper portions of the tongue at least partially integrate with the groove portion 51b. Figure 1 shows the tongue groove. This first operation forces the joining edges of the floor members to occupy the same relative vertical position over the entire length of the floor member and any Iv-shaped deflection can therefore be straightened.

69If you move my flap towards my tongue, the connecting wind on the burst element will rise slightly in this position. A. 4b edge is then bent upwards by a slip gate, while at the same time being held in contact with the tongue or in the FI direction, towards the edge portion 4a 5, as shown in FIG. When the edge portion 4b reaches an angle SA relative to the substrate corresponding to the upwardly elevated hepstin wall position, the honey shown in FIG. 44, as described above, can be moved to edge 4a to the portion 4a. 61 surfaces come into contact with each other, and the tongue closure elements partially engage in the closing elements of the tongue groove by a snap,

This imprinting operation in an upwardly curved position is such that the outer portions of the tongue groove are inclined and then tapered. The dilution juice is less than if the detection was done in a horizontal position. The tip of the SAFIN depends on the force that the elements are printing together to bend the edge portion 4b 15 upward. If the thrust in the Fi Direction is high, the elements will snap at a smaller SAR angle as if the force were smaller. The characteristic feature of the printable position is that the leading means of the closing means is the realization of their members. When the elements are in the form of bananas, then they are 20 and locked in the row of hips. The edge portion 4b, towards the connecting edge IS, can be bent downward by the combination of the pressure and angular motion S2 as shown in Fig. 51e, and can be retracted to its final position relative to the tongue. This is 5 ff. Figure

Depending on the design of the binding, it is also gifted to have a high accuracy of determining the angle of SA that provides the best result with the requirement that the squeezing should take place with a reasonable amount of force, and that the leading portions of the closure elements should be in a relationship. to prevent or hold together any shape of the banana so that the final closure is connected to the

It will also be appreciated that this may be combined with other pressures applied to other parts of the floor support by means of a plurality of matching trees, as well as the use of various auxiliary means, such as an auxiliary angle adjusting element, such as the spear and other such means. The same procedure can be used if someone wants to set the groove side of the new paddle at a certain angle and want to fit it with the lining of the already laid floor
    The description is further illustrated by examining various aspects of the laying device or tool. Such a tool, which serves to lay the floor elements with the tongue and groove of the tongue and groove of the floor elements, can be formed as a press 80 having a stop edge 82 that contacts the parts 4a, 4b which are the contact edges of the floor element.
