Definitions

  • Known tongue and groove connections of wood panels are usually such that a groove of constant width, measured in the direction of the thickness of the panel, is incorporated at the edge of one panel and that a tongue of constant thickness, measured in the direction of the thickness of the other panel, is incorporated Panels, protrudes.
  • the width of the groove and the thickness of the tongue correspond to one another, so that when the tongue and groove are pushed together to connect the two panels, they are mutually fixed in both opposite directions perpendicular to the rear surface of the panels. It was found that with this type of tongue-and-groove connection, inserting the tongue into the groove sometimes makes it difficult and that the tight tongue-and-groove fit allows the panels to work freely on the connection, especially when the wood shrinks while drying out. with special needs. In addition, the attachment of the panels to the grooved edge on a substructure carrying the panels is relatively cumbersome.
  • Tongue and groove connections with the features mentioned in the opening paragraph are known (FR-A-1 370 782 and FR-A-1 451 772).
  • Fastening means in particular nails, can be conveniently attached to the edge protrusion of the one panel on the rear side of the groove.
  • the invention has for its object to make a tongue and groove connection between two adjacent wood cladding panels available, which leads to a significant ease of assembly of the panels and to an improved relative movement behavior of the attached panels.
  • tongue and groove connections are known in which the tongue and groove taper and open the side facing away from the rear surface are parallel to the rear surface (US-A-1 374 082 and FR-A-809 481).
  • the wood material does not project any further than on the front surface of the groove. It is not described to concentrate play between the groove and the tongue on the rear-facing side of the tongue and groove connection.
  • a protrusion behind the groove is formed there by the edge of the one panel projecting from the groove on the rear surface, which can be used for the convenient attachment of fastening means, in particular when nailing or screwing on or tacking onto the substructure.
  • the tapering of the groove and / or the tongue in combination with the play between the groove and the tongue both at the beginning of the insertion of the groove into the tongue and in the completely pushed-together state leads to the neighboring panel with its tongue being particularly easy in the Groove of an already attached panel can be inserted, whereby the play, even when pushed together, offers space at least in the area of the spring root or the groove opening for accommodating the end of a corresponding claw for fastening the panel to the substructure or the heads of other fastening means. If the groove is sufficiently large compared to the tongue, it is even possible to insert it at an initial angle of the panel to be assembled relative to the corresponding neighboring panel, which is followed by tipping into the mounting position. The tongue slides easily into the corresponding groove.
  • the above projection helps as a lower guide surface when inserting the tongue into the groove. Furthermore, movements of the panels relative to one another, for example due to temperature fluctuations, or the working of the panels, in particular due to changes in moisture, are facilitated. Finally, the tongue and / or the groove cheek on the rear side become more stable, since they close in the critical transition area the rest of the panel is thicker.
  • the panels consist of a wood material, in particular solid wood, which can be brushed on the visible or front surface of the panel. They are generally rectangular, often elongated, cladding panels.
  • the area of the tongue that comes into the area of the groove opening of the neighboring panel when the panels are installed is referred to as the tongue root.
  • This spring root usually represents the rear end of the spring at the transition to the rest of the panel of normal thickness, but it can also be a bit away from the transition described, for example if the spring height is greater than the groove depth.
  • the fact that the width of the groove is essentially continuously greater than the thickness of the tongue at the corresponding point means that the groove has a greater width over its entire depth from the mouth of the groove to the groove base than the thickness of the tongue at the corresponding point has, which results in the game described practically over the entire groove depth or spring height.
  • the contact surfaces formed by the tongue and groove surfaces parallel to the rear surface retain their position with respect to the rear panel surfaces or the substructure even in the event of relative displacements of adjacent panels. Due to the rear surface-side contact of the panels on the substructure, the tongue is at least essentially in contact with a groove wall on one side, so that despite the play mentioned, the relative position of adjacent panels is defined correctly perpendicular to their rear surface. If, when fastening the wooden panels to the substructure, you work with claws that encompass the groove cheek on the rear side, there is the further advantage that the claws on the groove cheek, which tapers outwards or becomes thicker inward, hold precisely due to the elastic spreading. You can also use the claws in front of the Position the respective wooden panel on the groove cheek without it falling off easily, and then insert the wooden panel with its spring into the groove of the neighboring panel and position it on the substructure and fasten it with the claws.
  • the invention further relates to the wooden panels themselves, which are designed so that they allow the creation of tongue and groove connections described above with corresponding neighboring panels, cf. Claim 4.
  • the panel 2 on the right in FIG. 1 has a groove 4 in its left edge which runs perpendicular to the plane of the drawing along the edge of the panel 2.
  • the upper wall or boundary surface 6 of the groove 4 in FIG. 1 is parallel to the rear surface 8 and to the front surface 10 of the panel.
  • the groove base, which is semicircular in section, is denoted by 12, and the groove opening pointing to the left is denoted by 14.
  • the lower wall or boundary surface 16 of the groove 4 in FIG. 1 is inclined at an angle in the range from 8 to 15 ° to the rear surface 8 such that the width w of the groove 4, measured perpendicular to the rear surface 8, extends from the groove mouth 14 continuously reduced in the direction of the groove base 12.
  • the edge of the panel 2 projects further to the left than above the groove 4, that is to say on the front surface side of the groove 4. As a result, a protrusion 18 is formed. Above the groove 4, the edge of the panel 2 runs at right angles to the rear surface 8 and the front surface 10 for a piece of the panel height. Then there is an initially concave and then convex curvature for a visually appealing, smooth transition into the front surface 10.
  • the panel 2 on the left in FIG. 1 has a spring 20 on its right edge in FIG. 1, the upper surface or boundary surface 22 of which is also parallel to the rear 8 and front 10 of this panel 2.
  • the lower surface or boundary surface 24 extends essentially at the same angle as the lower boundary surface 16 of the groove 4 relative to the rear surface 8 of the associated panel 2.
  • the height of the spring 22, measured horizontally in FIG. 1, from the spring root 26 to the free one Spring end 28 is substantially equal to the depth of groove 4 measured horizontally in FIG. 1 from groove base 12 to groove opening 14. Thickness d of spring 20, measured vertically in FIG.
  • the left panel 2 can be inserted with its tongue 20 into the groove 4 of the right panel 2, with play remaining between the lower boundary surfaces 16 and 22 when pushed together.
  • this insertion is extremely easy due to the play, supported by the semi-circular rounding of the free spring end 28 and the projection 18 serving as a support surface. initially even inserting the tongue 20 into the groove 4 obliquely from above. If necessary, you can also slightly round off or chamfer the right edge of the left panel 2 at the transition to the rear surface.
  • FIG. 2 shows the pushed-together state of the two panels 2.
  • a fastening claw 26 can be seen, which in the section of FIG. 2 has the shape of a lying, open to the right U with a lower, horizontal extension leg to the left Has.
  • the U of the claw 26 encompasses the overhang 18 from above, left and below.
  • the left panel 2 rests on the lower leg of the claw 26, which is elongated to the left.
  • the claw 26 is pushed onto the overhang 18 from the left and nailed to the supporting substructure with a nail 28 through the left extension leg before attachment of the left panel 2 .
  • the upper, almost horizontal leg of the claw 26 takes place in the space between the spring 20 and the lower boundary surface 16 of the groove 4.
  • the relative position of the two panels 2 in is determined in spite of the lower play between the tongue 20 and the lower groove boundary surface Given direction perpendicular to the rear surfaces 8.
  • the tongue 20 and the groove 4 are milled out of the material of the panels 2. In the drawn design, the left panel can be inserted at an angle of 45 °.
  • the protrusion 18 described has the further advantage that viewing openings through the butt joints between adjacent panels 2 are prevented everywhere in the lining created with the panels 2, even where this protrusion 18 is milled away at the corner of the panel because of the transition into an edge provided with spring 20 is because either a spring 20 or a projection 18 cover the butt joints between adjacent panels 2 everywhere, even when the wood of the panels 2 shrinks and the butt joints become larger as a result.
  • Such situations occur with panels which are each formed with a groove on two adjoining edges and with a tongue on the other two adjoining edges.
  • the tongues and the grooves in the panel according to the invention can be succinctly described as wedge-shaped, possibly rounded at the end.
  • the illustrated exemplary embodiments can be modified such that in the case of a wedge-shaped tongue 20, the groove 4 has the surface 16 parallel to the surface 6 at a distance from the groove opening 14, or that in the case of a wedge-shaped groove 20 the tongue 4 has the surface 24 parallel to the surface 22.
