Description

  • The invention relates to floorboards. As floorboards below any floor covering is considered, in which at least two identically constructed elements are engaged with each other.
  • Examples of claimed in the context of the invention floorboards include prefinished parquet with a wear layer that is designed in the manner of a ship's bed parquet or like a plank. The floorboards also include three-layer planks, which are made up of three approximately equally strong layers, preferably of solid wood or veneer. Floorboards that are claimed in the invention are often constructed of three layers. Examples include prefinished parquet with a thin wear layer of veneer or solid wood, a central layer of glued or glued bars and a Gegenzuglage of inferior veneer or solid wood. The layers are offset with the main fiber direction approximately 90 ° to each other in order to achieve maximum dimensional stability. Layered boards are usually constructed of three approximately equally strong and qualitatively approximately equivalent layers of solid wood or veneer. For individual products veneers or floor racks can also be replaced by wood-based material layers or boards.
  • Now that prefabricated parquet or floorboards have been offered as products that need to be glued together, there is now a growing demand for floorboards that can be form-fitted without glue. While profiles for the long sides of floorboards have been developed relatively quickly, there is still a need for profiles which are particularly suitable for connecting floorboards to one another at the ends. In the case of front connections, disproportionately high forces are to be taken into account by the wood-typical shrinkage and swelling and, as a rule, by the very long plank elements.
  • The is known in the DE 100 01 076 proposed solution, which requires, however, by deep cuts a significant weakening of the floorboard.
  • Next will be in the WO 00/47841 proposed to provide floor panels on all sides with a profile in which a perpendicular to the plate plane to be closed connection is proposed, which provides groove, spring and locking elements. The locking elements should have a horizontal contact surface and prevent displacement of the floor panels perpendicular to the plane of the plate. The locking elements should be elastic. A disadvantage of this solution is that either separate components must be inserted or glued, which represent parts of the locking elements and must be positioned very precisely for exact locking. This is laborious. Another disadvantage is that the locking elements can be easily damaged when joining, if they are based on the in the WO 00/47841 proposed manner have horizontal contact surfaces.
  • Prior art profiles for joining floor elements are further apparent from the documents WO 01/98604 A1 such as DE 200 08 708 U1 known. A post-published, related to a panel and a fastening system for panels related art is in the WO 03/016654 A1 disclosed.
  • It is therefore an object of the invention to provide a profile for the vertical joining of at least two floor panels, which is easy to manufacture and safe to operate
  • This object is achieved by a profile according to claim 1 of the invention. The profile for vertically connecting at least two floor elements along a vertical plane of movement, which are each provided with an upper side, a lower side, two longitudinal sides and two end sides, has the following design features:
    • a groove attached to a first end face of a floor member;
    • a spring which is attached to a second end face of a floor element, and
    • arranged on tongue and groove, corresponding locking elements that define at least two to be connected floor elements in their vertical assignment, further points
    • the locking elements obliquely arranged contact surfaces, and
    • either the spring of the profile or tongue and groove are elastically deformable, wherein
    • the spring is formed in two parts, wherein on a first elastic spring part, a first part of a corresponding locking element is arranged, while the second spring part is rigid, wherein
    • a free space developed between the bottom and the bottom of the floor element is formed between the first and second spring parts,
    • the free space, based on the surface of the floor element and the plane of movement of the joining process of the floor elements, obliquely, whereby the first elastic spring part, starting from a wide base near the top of the floor element narrow tapering to the free end is formed elastically.
  • These elements, which are usually designed as latching lugs and corresponding recesses, act together in each case and fix the floor elements to be connected against each other in a predetermined position. In general, they prevent perpendicular to be closed profiles shifting vertically to the floor of the floor element or, the surface of the floor element. The corresponding locking elements therefore have a common investment line or surface. Unlike in horizontal, so parallel to the top of the floor element extending contact surfaces even a simply inclined contact surfaces enough to ensure a secure locking. At the same time allows one sloping contact surface a simpler and more gentle for the locking elements joining the profile and thus the floor elements.
  • The elastic deformability of spring or tongue and groove, so the deflection of spring or tongue and groove when joining the profile or second floor elements also contribute to the protection of the locking elements and of tongue and groove. The deflection of the spring or tongue and groove protects the corresponding locking elements when they are engaged in the assembly of the floorboards with each other.
  • The floor elements or planks to be joined are set particularly effective in their horizontal position to each other when groove and tongue are formed as a cone. This positive connection of the profile fixes the two floorboards in a simple and safe way. The taper of tongue and groove can be maintained, even if corresponding locking elements or special embodiments of tongue and groove are provided. It is sufficient if tongue and groove are at least partially designed for conical engagement.
  • According to an advantageous embodiment, the spring of the profile is designed so that it is deflected during assembly of the profile, and then return to the starting position after the successful engagement of tongue and groove. This elasticity can be produced by the required free space, which is required for the engagement of a lip of the groove, worked so deep that the remaining connecting web to the profile or, to the floor element allows a deflection of the spring. This embodiment proves to be advantageous because on the one hand there is no deflection on the underside of the profile, so that it is unnecessary to take measures that allow such a deflection in the direction of the base of the floorboards. On the other hand, this embodiment causes the formation of undesirable joints between the end faces of second floor elements is avoided.
  • According to the invention, the spring of the profile is formed in two parts. A first spring part is elastic, a second spring part is rigid. At the elastic first spring part, a first part of a corresponding locking means is arranged. The great advantage of the two-part spring is that the deformation processes during assembly of the profile do not cause the tongue or groove or parts thereof to move beyond the top or bottom of the floor elements during assembly.
  • In general, the elastic first spring part can be designed so that a deformation and deflection during assembly of the profile is made possible. However, according to the invention, a free space is created between the first and second spring parts, which allows a deflection of the first spring part onto the second spring part. This embodiment is to be produced by means of conventional tools and methods, for. B. to milling. The space runs obliquely according to the invention-based on the top of a floor element. The exact design of the free space can be chosen in coordination with the material used for the profile and the profile itself.
  • An embodiment of the inventive profile, with which a joint-free joining of the end faces of floor elements can be ensured in a simple manner, is designed so that the spring has a first part of a corresponding locking element that can be engaged with a second part of the corresponding locking element. This second part of the corresponding locking element is attached to a short, free lip of the groove and faces the spring.
  • The profile according to the invention requires a certain elasticity of the material. Brittle material such. As high density fiberboard or materials with low bending strength such. As chipboard, are not well suited for the production of the above-described profile. It is therefore preferred if plastic, solid wood or plywood are used for the production of the profile. These materials, with good machinability with known tools on a sufficient elasticity to ensure the reliable functioning of the profile.
  • The profile according to the invention can, depending on requirements, either be prefabricated as a separate component, in order then to be attached to end faces of floor elements, for example by gluing in a groove in the front page. Is the material of the floor element, z. B. in the case of a solid wood floorboard, then the profile according to the invention can be machined out of the material of the floor element integrally.
  • Other profiles that are suitable, especially the front sides of floorboards to connect with each other, are proposed in the invention.
  • With reference to the attached figures, the terms used in connection with the description of some embodiments of the profiles proposed according to the invention will be explained in advance. Show it:

  • The FIGS. 1 . 2 . 3 . 5 and 6 illustrate exemplary, facilitating the understanding of the invention embodiments, which are not covered by the invention.
  • Fig. 1a shows a groove-shaped end face 2 of a floorboard 1 and a spring-shaped end face 4 of a floorboard. There are - as will be explained below - after laying the floorboards always a groove-shaped and a spring-shaped end face of two floorboards engaged with each other. Accordingly, a floorboard 1 each have a first groove-shaped end face 2 and a second spring-shaped end face 4. The floorboard is constructed in three layers. The dashed lines in the figures indicate the three layers of the floorboard. It has a wear layer on the upper side 6. The underside 8 of the floorboard can be made of any material.
  • The groove-shaped end face 2 has a groove 10 with a long lip 12 and a short lip 14. The lips 12, 14 of the groove 10 are interconnected by the base 16. The groove 10 is worked out from the top 6 of the floorboard 1 forth, usually milled.
  • The federformige end face has a spring 18 which is delimited by a free space 20 of the end face 22 of the floorboard 1. The spring 18 is worked out from the bottom 8 of the floorboard 1 forth, usually milled.
  • Out Fig. 1b It can be seen that when joining groove 10 and spring 18, the free surface of the long lip 12 and the free surface 24 of the spring 18 facing each other. The free end 26 of the spring 18 is the base 16 of the groove 10 facing. The short lip 14 of the groove 10 protrudes into the free space 20 of the spring-shaped end face 4.
  • Fig. 1c shows the groove-shaped end face 2 and the spring-shaped end face 4 of the floorboards 1 with each other in engagement. The free space 20 facing surface 28 of the spring 18 abuts against the long lip 12 facing surface 30 of the short lip 14. The free end 26 of the spring 18 is the base 16 of the groove 10 facing, but is not necessarily on the base 16 at. The free end 32 of the short lip 14 faces the base surface 34 of the free space 20, but is not necessarily adjacent to the base surface 34.
  • There, where the spring 18 with the free space 20 facing surface 28 bears against the surface 30 of the short lip 14, a pressure surface 36 is formed. Starting from the pressure surface 36, a pressure force is exerted on the contact surface 38, which is formed by the fact that the groove-shaped and the spring-shaped end face 2, 4 of the floorboard 1 abut against each other at the top 6. Both the pressure surface 36 and the contact surface 38 may be formed point or line. Preferably, the surfaces 36, 38 but also actually formed flat.
  • In order to facilitate the joining of the end faces 2, 4 of the floorboards 1, the free end 26 of the spring 18 is narrower than the base 16 of the groove 10. Further, for easier assembly of the end faces 2, 4, the free end 26 of the spring 18, the free end 32 of the short lip 14 of the groove 10 and the base 34 of the free space 20 at the transition to adjacent surfaces each formed with rounded or chipped or bevelled edges. Correspondingly, the end face 22 of the free space 20 and the end face 40 of the short lip 14 of the groove 10 are spaced apart from each other after assembly.
  • In order to achieve the largest possible contact surface 38, the free surface 24 of the spring 18 is designed in such a way that it protrudes further in a first section 42 in the region of the top 6 of the floorboard 1 as in a second section 44 in the region of the central layer 46th Accordingly, the outer surface of the long lip 12 of the groove-shaped end face 4 in the region of the top 6 of the floorboard 1 has a first portion 48 which is further excluded than the base 16 of the groove 10. At this first section 48 closes to Base 16 of the groove 10, a second portion 50 which extends approximately at right angles to the base 16 of the groove 10.
  • Fig. 1c shows that the sections 42, 44 and 48, 50 are worked out corresponding to each other. The joining of the two end faces 2, 4 is thereby greatly facilitated.
  • Fig. 1c further clarifies that the contact surface 38 is well defined better. Since the contact surface 38 substantially determines the visual appearance and the qualitative impression of the laid floorboards, the profiles, which are extremely easy to produce, make the desired high-quality, because they are jointless, associated with wooden floors by the customers Impression conveys.
  • The above-explained embodiments of the profiled floorboards 1 effect with a simple formation of tongue and groove a surprisingly reliable, joint-tight connection of the end faces of two mutually engaged floorboards. At the same time, by generating compressive forces, the floorboards are prevented from shifting in the vertical direction, relative to the top or bottom of the floorboards, after assembly.
  • Fig. 1a shows an embodiment of the profiled floorboards, in which by the design of the spring 18, the application of the compressive force on the abutment surface 38 and preventing the displacement of the end faces 2, 4 in the vertical direction by a two-part spring 18a, 18b is effected.
  • From the underside 8 of the floorboard 1, a first free space 20a is worked out, to which a first spring 18a adjoins. The spring 18a has a surface 28 directed towards the free space 20, which, after joining the floorboards 1, engages with the surface 30 of the short lip 14 directed towards the long lip 12. The first spring 18a is formed so that it is hardly deflected when joining the groove-shaped end face 2 and the spring-shaped end face 4. At the free end 52 of the spring-shaped end face 2, a free space 20 b adjoins the spring 18 a, which is bounded towards the free end 52 by a second spring 18 b. The free space 20b projects closer to the upper side 6 of the floorboard 1 than the free space 20a.
  • The spring 18b is deflectable relative to the spring 18a when joining the end faces 2, 4 (see Fig. 1b ). Toward the intermediate space 20b, the spring 18b is designed with a straight surface 54. Towards the free end 52, the spring 18b is provided with a latching nose 56 at its free end 26b.
  • The groove 10 is provided in the region of the long lip 12 with a latch 58, under which the detent 56 of the spring 18b engages after assembly of the floorboards 1. This results after the joining of the groove-shaped end face 2 and the spring-shaped end face 4 of the floorboards 1 next to the first contact surface 38, a second contact surface 60, which, however -related to the top and bottom 6.8 of the floorboard 1- obliquely aligned (see Fig. 1c ). By the contact surface 60, a displacement of the floorboards 1 against each other is prevented. The free space 20 b is dimensioned so that the spring 18 b can be deflected during assembly by the latch 58. The joint-tight assembly of the groove-shaped 2 and spring-shaped 4 end faces is -as in the previously described embodiments of Fig. 1-3 - By the spring 18 a and the short lip 14 through which the pressure surface 36 is formed, guaranteed.
  • The in the Fig. 2a to 2c illustrated embodiment is particularly advantageous for floorboards that are to be repeatedly assembled and disassembled, for example, temporarily installed floors in exhibition or exhibition halls. It is an embodiment based on the in Fig. 1a to 1c variant has been developed.
  • The groove-shaped end face 2 has a groove 10, the groove base 16 is relatively flat, so that a stronger layer of material on the bottom 8 of the floorboard 1 remains. Accordingly, the short lip 14 of the groove 10 with respect to the groove bottom 16 is less high than in the Fig. 1a to 1c shown embodiment. The short lip 14 of the groove 10 protrudes, based on the thickness of the floorboard 1, preferably not in the upper half of the floorboard 1 into it. The long lip 12 is provided with a latch 58 which, after the joining of the corresponding ends of the floorboards, is engaged by a latching lug 56 of the spring 18b.
  • The springs 18 a and 18 b are formed corresponding to the dimensions of the groove 10. The clearance 20a is made less deep with respect to the reduced in height short lip 14. This benefits the stability of the floorboard. The space 20 b, however, is still deeply cut to allow a deflection of the spring 18 b when assembling the floorboards (see FIG. Fig. 5b ).
  • Fig. 2c shows the floorboards after assembly. Pressure surface 36 and contact surface 38 are joined together in the manner of a cone. Latch 56 and latch 58 are located on the second bearing surface 60 to each other. Between the spring 18b and the groove 10, a free space 62 is provided below the second bearing surface 60. The spring 18b is dimensioned correspondingly short. This facilitates on the one hand, the joining and releasing the floorboards 1 from each other. On the other hand, an unnecessary and unwanted clamping or friction by dust or grinding or milling residues in the groove 10 is avoided.
  • The spring 18a is likewise supported on the groove base 16 only with a relatively small bearing surface 64. The support surface 64 is - and this applies to all profiles described above - only sized so large that an alignment of the floorboards is guaranteed in terms of height. Otherwise, a free space below the spring 18a is provided to the groove bottom.
  • Despite the complex division of functions, the profile is in Fig. 1a to 1c and 2a to 2c illustrated floorboard easy to make. There are only a few, well producible undercuts to work out.
  • It is noted that the above-described, essential to the invention separation of functions (secure against longitudinal displacement of the floorboards and secure against a vertical displacement of the floorboards) on the principle of cone clamping on the one hand and the locking means On the other hand, a spring can also be designed in a completely different arrangement of the profile. For example, it is conceivable that the latching takes place in the region of the short lip of the groove or that a latching takes place between the short lip of the groove and the spring-shaped end face of the floorboard:
    • Fig. 3 ac shows a profile in which the locking has been further improved so that now the gap between the floorboards during assembly is not opened. In this profile, a pin 66 is still inserted at the bottom of the groove on which the spring 18a rests with a pressure surface 36 after assembly. Next, the spring 18a forms a contact surface 38 after assembly with the long lip 12 of the groove-shaped end face 2, so that the cone-shaped clamping is ensured to secure against horizontal displacement. The spring 18 b engages between the pin 66 and the short lip 14, wherein after joining the floorboards a second abutment surface between a latch 58 on the pin 66 facing side of the short lip 14 and a latching nose 56 is formed on the spring 18 b.
    • Fig. 4 ac shows an embodiment of the profile according to the invention, which is similar to the first embodiment. However, the free space 20b is not arranged at right angles to the upper side 6 of the floor element 4, but obliquely, approximately at an angle of 25 °. The elastic spring 18b is correspondingly formed from a broad base near the upper side 6 of the floor element narrowly tapered to the free end 26b towards elastic.
    • Fig. 4b clearly shows the deflection of the elastic spring 18b when, when joining the floor elements 2.4, the locking elements slide past each other to - as in Fig. 4c shown - finally come along the inclined contact surface 60 into engagement.
  • In the Fig. 4 ac illustrated embodiment clearly shows that even a narrow clearance 20b is sufficient to allow an elastic deflection of the spring 18b.
  • The spring 18a is rigid. Unlike the resilient spring 18b, the rigid spring 18a has a widened free end 26a relative to the width of the base near the top 6 of the floor element 4. This favors the effect of the cone, which is formed by the assignment of pressure surface 36 and contact surface 38, and prevents horizontal sliding apart of the floor elements 2.4 relative to the plane of the top 6.
  • Fig. 5 ac shows a the understanding of the invention facilitating, but not falling under the invention profile in which the corresponding locking elements are not - as usual - on the free surface 24 of the spring or the long lip 12 of the groove are arranged. Instead, a projection on the surface 20 facing the free space 20 is formed on the spring 18. A corresponding recess is formed on the short, free lip 14 of the groove, above the pressure surface 36. Projection and recess come after joining (see. Fig. 5c ) along the - with respect to the top of the floor element 4 oblique contact surface 60 for engagement.
  • This embodiment offers the advantage that a virtually joint-free installation of the end faces of two engaging floor elements is ensured.
  • If the material, in particular the middle layer of the floorboard, does not allow to work out the profiles according to the invention, the following method is available:
  • When laying the middle layer, the length of the boards to be produced is known. In each case in the region of the end faces, a high-quality material is inserted instead of the material not suitable for producing the profiles, which makes it possible to work out the profile. This material may be wood, plastic or metal or other suitable material for producing the profile and for absorbing the forces arising. For an inventive profiling of the front sides of the floorboards is possible.
  • Alternatively, after the manufacture of the floorboards still unprocessed floorboards a recess can be created, which is inserted the above-described, suitable for the production of the profiles material and connected to the floorboard. Also in this way a profilierbare front side of the floorboard is made.
  • Finally, an already profiled material can be used in the method last described.
  • The compound proposed by the invention has a contact surface between the groove-shaped end face and the spring-shaped end face of the floorboard in the area of the wear layer and a pressure point which is arranged in the region between the base of the groove and the short lip of the groove which is arranged on the end face of the floorboard and the spring is on the other hand. By the pressure point, which is formed between the spring and short lip of the groove, when two corresponding end faces of the floorboards are engaged with each other, it is ensured that the contact surface between the groove-shaped and the spring-shaped end side of the two floorboards is under compressive load, so that a Joint formation or detachment of the two floorboards is excluded. The spring engages after assembly as a cone clamped in the groove and thus causes a fixation of the floorboards to each other. This type of cone clamping is simple and effective.
  • According to a preferred embodiment of Invention is the end face of the spring, which faces the groove-shaped end face, provided with a step. The furthest protrudes from the contact surface, which is arranged on the long lip of the groove in the area of the effective area. Below the contact surface, towards the free end of the spring, the end face of the spring is narrower, so that a recessed step is formed. The spring-facing surface of the long lip of the groove is formed correspondingly. Below the contact surface, a projection is formed whose dimensions correspond approximately to the dimensions of the recessed step of the spring.
  • In the embodiment described above, the contact surface is designed to be particularly wide, so that the requirement to ensure a frontally gap-free connection of the floorboards to each other, is certainly met.
  • The above description relates primarily to the design of the end faces of floorboards. If necessary, however, the longitudinal sides of floorboards can be designed accordingly.
