Definitions
- the invention relates to a panel made of a square plate made of coated wood-based material, wherein opposite edges of the panel have mutually complementary positive-locking profiles, so that similar panels can be joined together.
- Generic panels are used, for example, for the production of floor coverings, so-called laminate panels. Such panels can also be designed as wall or ceiling panels.
- the panels predominantly consist of medium-density fiberboard (MDF) or of high-density fiberboard (HDF), onto which other layers, mostly resin-impregnated cellulose layers, are laminated.
- MDF medium-density fiberboard
- HDF high-density fiberboard
- the positive locking profiles are formed in one piece on the panels, for example milled.
- the panels are rectangular with two long edges that lie opposite one another and with two short edges that lie opposite one another.
- the thickness of the laminate panels is usually less than the thickness of parquet panels. Usual thicknesses are in a range between 5 mm and 8 mm. Thinner or thicker laminate panels are rare. However, parquet panels are now also equipped with form-fitting profiles. Therefore, the positive locking profiles of the proposed new panel can also be provided on parquet panels.
- the complementary form-fitting profiles of a panel are limited by the thickness of the panel and are quite small. They have to be made with a very good shape and fit so that they fit together. High fit of the complementary shape End profiles are an important requirement, in particular to ensure a closed joint on an upper side of the locked panels, because the surface is visible to the user of a finished floor covering. For floors in particular, it is desirable to have a smooth surface in which the joints between the panels do not form gaps, but the edges are butted against each other and are in contact.
- one of the complementary form-fitting profiles can be viewed as the inner part and the associated profile as the outer part.
- the relationship of an outer part to an associated inner part before joining the parts is called a fit.
- Both the outer part and the inner part have certain nominal dimensions, tolerances being permitted for each nominal dimension. Any form-fit profile whose actual dimensions are within tolerance can be used. Fits are classified into three different types according to a system: match fit, press fit and transition fit. The subdivision is always based on the dimensional relationship of the outer part with its tolerance to the inner part with its tolerance before the joining of both parts.
- the tolerances are such that there is in any case an oversize between the outer part and the inner part after the joining and therefore there must be an elastic deformation of the joining parts.
- WO 97/47834 In order to always obtain a closed joint for the panels on the upper side of the panels, which is visible in the installed state, it is known from WO 97/47834 to bring about an elastic deformation on a form-fitting profile, which produces a prestressing of the panels. By means of this prestressing, the panels are forced towards one another and in this way the joint on the 0- top side of the panels is kept closed.
- the panel known from WO 97/47834 is a modified tongue and groove panel, tongue and groove being undercut in each case.
- the geometry of the interlocking profiles causes elastic deformation on one of the groove walls, namely the lower groove wall facing the laying substrate in the installed state.
- the deformed lower groove wall bends like a beam clamped on one side. When two panels are installed, the deflection of the groove wall is at least partially preserved. Due to the elasticity of the lower groove wall as well as the special geometry of the groove wall and tongue, in which inclined planes act on one another, the joint is closed
- the internal cohesion of the wood material is disadvantageously weakened by the permanent deflection.
- the higher the degree of deformation the "more" the wood material becomes in the area deformed by bending.
- Another disadvantage is seen in that the wood material relaxes in the area deformed by bending over a long period of time.
- Moisture absorption of the wood material promotes relaxation
- the form-fitting profiles of panels are usually impregnated with agents that do not Prevent moisture absorption, but depending on the quality of the impregnation and the type and location of the panel application, a gradual moisture absorption cannot be prevented.
- the invention is based on the object of proposing a panel whose form-fitting profiles are designed such that, in the assembled state, panels have closed joints without at the same time producing an elastic deformation of a form-fitting profile which is stressed by the wood-based material.
- the object is achieved in that the surface of the interlocking profiles has elevations and depressions at least in some areas, that the elevations are abraded by friction during assembly of two panels, and that the depressions have a volume in which the abrasion particles from the elevations arise are recordable.
- the elevations are ground to the required size.
- a closed joint forms at the top of the panels.
- a uniform height level is achieved without a height offset at the joint.
- the positive locking profiles can enlarge or swell due to exposure to moisture. In these cases, the bumps continue to be abraded through proper use, namely on a soft footfall sound-absorbing surface. The fit of the form-fitting profiles is adjusted again and, as a result, a suitable seat without oversize and without play.
- One of the form-fitting profiles is expediently designed as a groove profile with an undercut and the opposite form-fitting profile as a tongue profile with an undercut.
- the undercuts of the tongue and groove profiles can be inserted into one another by tilting the panels.
- a connect- folding the panels into a common plane locks them.
- the locking acts in the plane of the panels against pulling apart in a direction perpendicular to the interlocking profiles.
- a panel usually lies flat on a laying surface and a new panel is placed at an angle to the lying panel.
- the new panel is folded into the common level by lowering it onto the laying surface.
- the undercuts of the groove profile and tongue profile engage behind. This locks the panels.
- the positive-locking profiles are ground in one another for a long time by a subsequent back and forth swiveling movement until the groove profile and tongue profile fit.
- the panels are connected in an articulated manner, that is to say the tongue profile is mounted in the groove profile in a manner similar to an articulated body, which forms a type of socket. As a result, the panels can be pivoted from an angular position of 180 ° to one another both in the positive and in the negative direction.
- the articulation of the joints enables a particularly good reciprocating grinding movement.
- they Before the final laying of the panels on the installation base, they can be loosely put together on a table, for example, to determine the extent to which they have to be sanded in so that a precise fit is achieved.
- accuracy of fit can be checked at the free end of the locked panel surface because the connection of the form-fitting profiles is visible from the side. It can be seen whether the positive locking profiles are deformed.
- a measurement of the total thickness of the locked panels in the area of the connected panels can be carried out, for example Form-fit profiles are made. If the total thickness exceeds a specified limit, the grinding-in process must be continued.
- the elevations and depressions are preferably provided on the tongue profile and the groove profile has a smooth surface.
- the smooth surface of the groove profile is in contact with the elevations of the tongue profile in the form-fitted state.
- the elevations and depressions are expediently arranged on a spring underside of the spring profile, which faces a laying substrate. In this way, the shape of the profile is adapted to the desired function. Because a panel is attached to the groove profile of a lying panel by slanting a tongue profile, the construction makes use of this joining movement to grind and adjust the elevations. Both in the subject matter of claim 1 and in the development with elevations and depressions on a spring underside, an adjustment of the fit dimensions and the fit of the form-fitting profiles takes place during assembly.
- the form-fitting profile with the elevations has a “more” material.
- there is an excess before joining During the joining process, material is ground off from the elevations and the excess is eliminated a connection that has neither an excess nor a play.
- the form-fitting profiles have been precisely adapted to ensure a closed joint.
- the stiffness of the form-fitting profiles and the abrasion resistance of the elevations are expediently coordinated with one another in such a way that forces generated during During assembly, abrasion of the elevations can be achieved, but there is no elastic deformation of the interlocking profiles.
- the elevations and depressions on the interlocking profile or profiles can be designed as a microstructure which is incorporated in the surface of the interlocking profiles.
- a further advantage is provided by a sealant and lubricant, which is provided at least in the recesses. The lubricating effect makes it easier to join the panels together using a rotating joining movement.
- the elevations on the interlocking profile can be grinded better by wetting than in the dry state.
- the elevations can break off when dry. Lubrication prevents breakage.
- FIG. 3 shows an advanced joining process compared to FIG. 2.
- FIG. 6 the positive locking profiles shown in FIG. 4 with lubricant.
- Figure 1 shows a detail of two panels
- each of the panels 1 and 2 has positive locking profiles on opposite sides, which are milled in one piece on the panel (s).
- the form-fitting profiles are a groove profile 3 with an undercut and a tongue profile 4 with an undercut.
- Each of the panels 1 and 2 has a respective complementary profile on opposite edges.
- the panel 1 is thus equipped with a complementary tongue profile on the edge opposite its groove profile 3 and likewise the panel 2 with the tongue profile 4 on the edge opposite the tongue profile 4 with a complementary tongue profile.
- Panels 1 and 2 are rectangular. These complementary profiles are also provided for the other two edges of the panels.
- the positive locking profiles 3 and 4 are shown before joining.
- Panel 1 lies on an installation base V.
- the panels are coated.
- a decorative coating of several layers is arranged on an upper side A of the panels facing away from the laying substrate V in the installed state.
- An underside B opposite the upper side is provided with a counteracting layer.
- the spring profile 4 of the panel 2 has a spring underside 4a with elevations 5, 6 and 7 and depressions 8 and 9.
- the spring underside 4a is in the assembled state of the panels 1 and
- the groove profile 3 of the panel 1 has a lower groove wall 10 facing the laying substrate V and an upper groove wall 11.
- the lower groove wall 10 has a channel-shaped receptacle 10a on its inside.
- the channel-shaped receptacle 10a receives the spring underside 4a of the panel 1 in the assembled state.
- the trough-shaped receptacle 10a is provided with a concavely curved surface, which is designed without elevations and depressions.
- the complementary design of the interlocking profiles relates to the basic shapes of groove profile 3 as outer part and tongue profile 4 as inner part, which fit into one another.
- the elevations 5, 6 and 7 and the depressions 8 and 9 on the spring underside 4a are not designed as a negative shape in the groove-shaped receptacle 10a of the groove profile. Despite these deviations between the form-fitting profiles 3 and 4, these are referred to as complementary form-fitting profiles in the sense of the invention.
- the free end of the groove wall 10 protrudes further from the edge of the panel 1 than the upper groove wall 11.
- the free end of the upper groove wall 11 protrudes from the edge of the panel approximately as far as the lowest point of the groove-shaped receptacle 10a.
- the lowest point of the trough-shaped receptacle 10a is the point which, perpendicular to the plane of the panel, has the smallest distance from the underside B of the panel 1.
- the upper groove wall 11 has a bevel 11a on its inside. Because of the bevel, the thickness of the upper groove wall decreases from its free end to the groove base of the groove 3.
- Elevations 5, 6 and 7 shown on the tongue underside 4a of the tongue profile 4 in relation to the shape and the dimensions of the groove profile 3 have an oversize.
- the connection of the tongue profile 4 with the groove profile 3 of the panel 1 forms a joint G in the assembled state.
- the joint G permits the panels 1 and 2 to move angularly relative to one another.
- the panels 1 and 2 are at an angle of 180 ° to one another. From this basic position, the panels 1 and 2 can be pivoted into a position with an angle greater than 180 ° relative to one another, as well as in a position with an angle less than 180 °.
- a position of the panels 1 and 2 at an angle greater than 180 ° to one another is described below with reference to FIG. 5.
- FIG. 2 shows how the form-fitting profiles are joined together.
- a panel 1 lies on the laying substrate V and with its groove profile 3 faces a new panel 2.
- the new panel 2 is inserted with its tongue profile 4 into the groove profile 3 of the lying panel 1, the new panel 2 being inclined or angled with respect to the lying panel 1.
- a first elevation 5 of the tongue underside 4a of the panel 2 comes into contact with the lower groove wall 10 of the groove profile 3.
- the tip of the elevation 5 rubs against the surface of the trough-shaped recess 10a and grinds against it.
- the resulting abrasion particles 5a get into the recess 8 and are carried in this during the further joint movement.
- Figure 3 shows the joining process in a further stage.
- a second elevation 6 has come into contact with the surface of the trough-shaped recess 10a and grinds thereon.
- the resulting abrasion particles 6a are stored in the recess 9, which is arranged behind the second elevation 6 in the direction of joining of the spring profile 4.
- the shape of the spring profile 4 adapts to the shape of the during assembly
- FIG. 4 The fully assembled state of the positive locking profiles 3 and 4 is shown in FIG. 4.
- a third elevation 7 has also come into contact with the surface of the trough-shaped recess 10a of the groove wall 10 and has been ground down on the latter.
- the resulting abrasion particles 7a are located in an intermediate space between the lower groove wall 10 of the groove profile 3 and the tongue profile 4.
- a closed joint F is formed on the upper side A of the panels facing away from the installation base V.
- the joint F is defined by an end face 11b of the upper groove Wall 11 of the groove profile 3 is formed and by a contact surface 12 provided on the tongue profile 4, which extends from the tongue top 4b to the surface of the panel 2. In this state, the end face 11b bears against the contact face 12 without pressure.
- the inner part - tongue profile 4 - of the panel 2 fits without play into the outer part - groove profile 3 - of the neighboring panel 1. There is no elastic deformation that is stressful for the form-fitting profiles.
- the peculiarity of the construction lies in the fact that the relationship of the fits of the form-fit profiles to be joined changes during the assembly process.
- the fit of the tongue profile 4 is matched to the fit of the groove profile 3.
- the groove profile can also be formed with elevations and depressions that grind off. It is irrelevant for the function of the connection at which point the adaptation takes place by grinding material.
- the number of surveys is not limited to three.
- a microstructure can be provided from a multiplicity of elevations which are significantly smaller than that of the exemplary embodiment explained.
- a “more” material is provided in the area of the elevations 5, 6 and 7 of the spring profile 4. This excess is ground off during the assembly of the positive-locking profiles until the fit of the inner part is matched to the fit of the outer part.
- the rigidity of the form-fitting profiles 3 and 4 and the abrasion resistance of the elevations 5, 6 and 7 are coordinated with one another in such a way that the elevations 5, 6 and 7 can be rubbed off by forces which occur during assembly, but none elastic deformation of the interlocking profiles 3 or 4.
- the positive-locking profiles 3 and 4 must be ground in on one another by a subsequent back-and-forth pivoting movement until Fit is achieved. It is also helpful for this that the panels 1 and 2 are connected in an articulated manner and can be pivoted from an angular position of 180 ° to one another both in the positive and in the negative direction.
- the joint G and its mobility is illustrated in FIG. 5, in which the panels 1 and 2 are at an angle to one another which is greater than 180 °. This enables a particularly good back and forth grinding movement.
- the panels 1 and 2 on the laying base V Before the final laying of the panels 1 and 2 on the laying base V, they can be loosely put together on a table, for example, in order to determine the extent to which they have to be ground in so that a precise fit is achieved. During installation, the accuracy of fit can be checked at the free end of the locked panel surface. There the connection of the form-fitting profiles 3 and 4 is visible from the side. It can be seen whether the positive locking profiles 3 and 4 are deformed. To objectively check whether there is any deformation, a measurement of the total thickness of the panels 1 and 2 in the area of the connected form-fitting profiles 3 and 4 can be carried out, for example. If the total thickness exceeds a predetermined limit, the grinding-in process must be continued.
- FIG. 6 shows an embodiment of panels 1 and 2, the form-fitting profiles 3 and 4 of which are treated with a so-called insulating wax. It is a means that causes lubrication for the joining movement of the positive locking profiles 3 and 4. In addition, the insulating wax is squeezed into free spaces 13a, 13b and 13c within the locked form-fitting profiles 3 and 4 and, for example, as thinner
- the insulating wax acts as a sealant.
- the sealant is applied in an amount that at least partially coats the surface of the interlocking profiles. This prevents the penetration of moisture into the joint F and thus into the wood-based material. The wood-based material would otherwise swell due to moisture absorption.
- the amount of insulating wax can fill the spaces 13a, 13b and 13c or be dosed a little less so that there is free space. Due to its lubricating properties, it also prevents creaking noises in the area of the form-fitting profiles 3 and 4 of the panels 1 and 2 because a lubricating film is formed.
- Creaking noises occur with panels 1 and 2 when there is a relative movement between the form-fitting profiles 3 and 4. This is the case, for example, when laying floor panels on a resilient underlay that absorbs impact sound, because panels 1 and 2 sink into the resilient underlay when the connection point is loaded.
