Description

  • The The present invention relates to a plate according to the preamble of claim 1. Such plates are mainly used for laying as a laminate floor, the use as ceiling and wall panels is also possible.
  • The US-A-4426820 discloses plates used to make a floor covering can be inserted into each other. The preferably made of plastic plates have a Art tongue and groove connection, wherein the spring are pivoted into the groove can. Therefor the spring is angled extending upper edge, so that the tapered spring profile be inserted into the correspondingly formed groove profile can. At the lower groove lip, a projection is formed, which as a locking means holds together two juxtaposed profiles. at the profile connection shown has the disadvantage that by this profile form no more complete Positive locking is achieved and can form small gaps, since the profiles held together only by the locking means are.
  • Furthermore, it is from the EP 843 753 known to provide a floor covering of a wood material, which is formed of a plurality of nested panels. The panels have on opposite sides grooves and springs which are pivotable or displaceable one inside the other. On the spring, a projection is formed, which cooperates with a formed on the lower groove lip locking means to generate a clamping force between the individual plates. The clamping force is provided by the elastic lower groove lip, which protrudes partially downwards, so that it is not possible to produce a flat floor covering from these plates. As soon as the plates are loaded in the area of the downwardly projecting groove lip, this leads to deformations on the plate. Furthermore, the clamping forces between the individual plates are limited due to the small height of the projection on the spring.
  • It is therefore an object of the present invention, a plate of the above to provide said type, in which the holding forces between two plates are laid in the laid state and some are improved allow planar interconnection of multiple plates.
  • These Task is with a plate having the features of claim 1 solved.
  • If a projecting portion of the spring profile, in the assembled state engages in the groove profile, is held in a wedge-like manner in the groove profile, will be added to other locking means generates a wedging effect, the holding the profiles together. The existing of wood material or lignocellulose material Plates have pores that are compressed when wedged into each other become. Once the material is slightly in the area of the wedge-like Spring would be compressed, occurs a minor one Expansion so that the spring is permanently clamped. In addition, the show Grooved profile and the spring profile a certain surface roughness on, which prevents a moving apart of the plates due to the clamping forces. This Wedging effect between spring and groove enables the production especially dense floor coverings, where the joined together Plates have a minimal water permeability.
  • At the groove profile is provided on the lower groove lip a thickening, at the inclined contact surface and a substantially parallel to the flat surface extending support edge is formed, and adjacent to the contact surface Gap between the lower groove lip and a portion of the spring profile is trained. Due to the flat bearing edge is at a load of the groove profile in the assembled State creates a clamping action by the contact surface, which is another press together the plates causes and even under extreme loads in this Area prevents movement of the plates apart.
  • According to one preferred Ausführungsform the Invention is the spring profile in the region of the wedge-shaped connection form-fitting held in the groove profile. To strengthen the holding forces here can additionally a clamping force over the contact surface of be generated lower groove lip.
  • Preferably wiest the protruding portion of the spring profile, an upper and a lower wall surface on, the inclined or curved to the flat surface run. To achieve a sufficient wedge effect, the For example, tilt 20 to 30 ° to even surface be. If the upper wall surface inclined and the bottom wall surface bent is formed, the spring profile can be particularly good in the groove profile added become. The curvature on the lower wall surface makes a guide to be able to pivot two plates into each other.
  • The Invention will be described below with reference to two embodiments with reference to the attached Drawings closer explained. Show it:
  • 1 a perspective view of him inventive plate;
  • 2 a cross-sectional view of a groove profile of the plate 1 ;
  • 3 a cross-sectional view of a spring profile of the plate according to the invention 1 ;
  • 4 a cross-sectional view of a groove profile and spring profile, which are just joined together;
  • 5 a cross-sectional view of a groove profile and a spring profile in the assembled state, and
  • 6 a cross-sectional view of a second embodiment according to the invention of a tongue and groove profile.
  • In 1 is a plate 1 from a lignocellulosic material, such as an HDF plate (HDF plate = High Density Fiber Board) shown on two opposite transverse edges a groove profile 2 and a spring profile 3 having. At the longitudinal edges are also a groove profile 5 and a spring profile 4 intended. The groove profiles 3 and 5 as well as the spring profiles 2 and 4 are identical, but it can also be used for the transverse or longitudinal sides of other profile types. The plate 1 can also be designed as a thin chipboard, plywood, OSB, plastic plate or mineral plate. The plate 1 may be coated with a decorative layer for use as a laminate floor.
  • The groove profile 4 has a contact edge 7 on that to the plane of the coating 6 runs vertically downwards. The groove has an upper sloping wall surface 8th , a curved bottom 9 and a curved bottom wall surface 10 on. To the curved lower wall surface 10 closes a flat floor area 11 at.
  • At the lower groove lip in the protruding area is a thickening 13 formed, whose height is about half the height of the plate. At the thickening 13 is a contact surface 12 formed, which inclined to the flat surface of the coating 6 runs. The inclination is dimensioned such that in cross section between tween the inclination and the perpendicular to a connecting line R from the upper edge of the contact surface 7 and the top of the coating 6 to the upper end of the contact surface 12 an angle β is formed which is between 5 and 15 °, preferably 10 °. At the thickening 13 is a support surface 21 formed, which runs parallel to the flat bottom surface. As in 2 is shown, forms the vertical of the wall surface 8th to the connecting line R from an acute angle, which may for example be in a range of 20 ° to 40 °.
  • The groove profile 5 points in the area of the coating 6 a contact surface 14 on, below a recess 15 is omitted. The front section of the spring profile 5 is through a top wall surface 16 , a rounded tip 17 and a lower curved wall surface 18 educated. To the curved wall surface 18 closes a reset section 19 on, which has a rounding with a contact surface 20 connected is. The spring profile 5 is following the contact surface 20 with a support surface 22 Mistake.
  • The joining together of a groove profile 4 and a spring profile 5 will be described below with respect to 4 and 5 described.
  • The spring profile 5 is initially loose in the groove profile lying on the floor 4 inserted until the contact surface 7 of the groove profile 4 at the contact surface 14 of the spring profile 5 the bottom wall surface 10 of the groove profile 4 on the lower wall surface 18 of the spring profile 5 and the contact surfaces 12 and 20 abut each other. In this position, the coating can 6 on the spring profile 5 still slightly above the surface 6 on the groove profile 4 protrude. Furthermore, in this position between the flat groove profile and the loosely fitting spring profile 5 an angle α is formed in the area of the surface.
  • To the newly laid plate with the spring profile 5 with the already laid plate with the groove profile 4 join together, the spring profile 5 in the Nutprofi1 4 pivoted. The curved lower wall surface is used 10 and the contact area 12 on the groove profile 4 as a guide, until the top wall surface 16 the spring on the upper wall surface 8th on the groove profile 4 is applied. This is the spring profile 5 slightly into the groove profile 4 moved in, so that a wedging of the spring profile 5 in the groove profile 4 takes place. This wedge effect also prevents that under load of the groove profile 4 in the region of the protruding portion of the spring profile 5 , this from the groove profile 4 is pushed out. Also a vertical load in the area of the contact surface 12 At most ensures a stronger wedging of the spring profile 5 in the groove profile 4 , as between the spring profile 5 and the section 19 the groove profile is formed a gap.
  • In 6 is a second embodiment of a compound according to the invention a groove profile 4 ' and a spring profile 5 ' two plates shown. In this embodiment, the groove profile 4 ' for receiving a spring profile 5 ' also with a facility 7 ' or wedge-shaped wall surfaces 8th' and 10 ' provided while on the spring profile 5 ' a contact surface 14 ' and wedge-shaped wall surfaces 16 ' and 18 ' are formed.
  • In the area of the lower groove lip is a thickening 13 ' provided, which has a lower height than in the first embodiment. This is also the contact surface 12 ' respectively. 20 ' shorter. To the spring profile 5 ' better in the groove profile 4 ' being able to introduce is a slant 21 ' on the groove profile 4 ' and a slope 22 ' on the spring profile 5 ' educated. In this embodiment, the spring profile 5 ' particularly uncomplicated in the groove profile 4 ' be introduced. The lower height of the contact surfaces 12 ' and 20 ' Although facilitates the introduction of the spring profile 5 ' in the groove profile 4 ' , but the holding forces are due to the thickening 13 ' also lower than in the first embodiment. The wedge effects are due to the identical design of the groove profile 4 ' and the spring profile 5 ' in this area, however, just as existent.
