Definitions

  • the invention relates to a covering of mechanically interconnectable panels according to the features of the claim.
  • Wall, ceiling and floor coverings such as parquet flooring, real wood floors or laminate flooring, consist of several rows of predominantly rectangular panels in their configuration.

  • Adjacent to the tongue and groove of the panels are mating locking elements in the form of recesses, recesses or projections to hold bonded floor panels in the assembled position glueless.
  • the panels are rotated along their longitudinal sides into each other or clicked and then moved laterally, so that locking strips on the head sides engage.
  • the springs are made of a different material than the panels.
  • the springs are integral with the material throughout the panel, there are some design limitations to prevent the springs from breaking. This is particularly relevant with respect to the usual floor panels with a core of wood chip material, for example MDF or HDF, which as such have only limited elasticity.
  • Plastic floor coverings are usually made of PVC in the form of individual tiles or panels that are glued together.
  • the impact sound transmission behavior of PVC floors is better because of the softer material compared to MDF or HDF, but the use of adhesives is required to bond the individual panels to the ground.
  • the invention has for its object to show a coating of mechanically interconnectable panels, which lay more quickly leaves as to be bonded to the ground panels, but still has an improved impact sound transmission behavior.
  • the panels have on their opposite sides a corresponding profiling. About this profiling, the abutting sides are locked together.
  • the panels have a core on which a spring is arranged, which is displaceable via a joining movement behind a substantially horizontally extending locking edge of the adjacent panel.
  • the core consists of a soft, elastic material from which the spring is uniformly formed ejn publishedig material together with the core.
  • the panels have a multilayer structure.
  • the spring is formed integrally with the core, so does not have to be connected by a separate manufacturing step with the core and not made of a different material than the core itself, the production of such panels is relatively inexpensive.
  • the problems resulting from the bonding, such as vapor diffusion caused by the adhesive layer or by rising moisture from the soil, are avoided.
  • Elastic materials according to the invention are in particular plastics, especially thermoplastics.
  • plastics especially thermoplastics.
  • Additives can be adjusted the elastic material properties. Decisive in the use of plastics in the soil area is that the plastics can deform under load, but on discharge relieve their original shape, so do not tend to cold flow or are brittle. Thermosets are therefore out of the question.
  • the group of thermoplastic materials includes polyvinyl chloride (PVC), polypropylene (PP), polyethylene (PE), polystyrene (PS), polycarbonates (PC) and polyacetals (POM).

  • the granular materials may be mineral materials such as carbonates such as limestone or dolomite.
  • the mineral material may consist entirely or partly of calcium sulphate, namely gypsum. According to the invention, however, the core is more elastic, more flexible and thus less brittle in comparison to pure fibreboard or gypsum boards.
  • the spring is pivotable behind the locking edge, wherein the spring to achieve the locking position is at least partially elastically deformed and remains elastically deformed after reaching the locking position.
  • the elastic deformation of the spring or the exploitation of this material property of the spring is an essential feature of the locking system according to the invention in connection with the fact that the spring is of uniform material integral part of the core.
  • a partially elastic deformation does not mean that the spring, comparable to a tight fit or a press fit, only slightly biased and therefore more likely to be compressed. It is rather necessary that To change spring in shape so far that the locking position can be achieved at all. For this purpose, parts of the spring must be significantly deformed, but all deformations should move in the elastic and preferably in the fully reversible area.
  • the spring in the unlocked position has a substantially arcuately curved course, at least in sections, and is provided in total elastically when being joined to the adjacent panel by contact with the adjacent panel in the region of its at least one arcuately curved profile deformed and thereby stretched in length.
  • the spring engages in the extended position, a locking edge of the adjacent panel.
  • the spring in the unlocked position has a shorter length than in the locked position, that is in its extended position.
  • the extension can be made by the accurate insertion of the spring into corresponding recesses of the profiling. The spring is thereby brought into the stretched shape, elongated and thereby transferred to a locking state in which the panels are held together.
  • the extension or elongation of the spring can only take place on a partial region of the spring, for example by displacing the regions of the spring further spaced from a straight central longitudinal axis of the spring in the direction of the central longitudinal axis. This can be done by flattening a projection in the form of an arc.
  • the spring can have several functional sections.
  • the spring has at its panel-side end a connecting portion. At its other, free end, it may have a locking portion.
  • the connecting portion and the locking portion can via a Joint section to be interconnected.

  • the joint section is therefore characterized by a smaller wall thickness in comparison to the connecting section or locking section.
  • the locking portion is adapted in its configuration to the profiling of the panel with which the locking portion engages.
  • the joint portion is thus optimized independently of the configuration of the locking portion on the function of the joint, while the connecting portion provides a captive grip of the spring on the core.
  • a spring having cavities can be reduced in locking, so that the spring lengthens to reach behind the locking edge.
  • the cavities are preferably connected to the atmosphere. As a result, no counterpressure can be built up. This facilitates the shrinking of the cavities.
  • the springs are preferably longitudinally channeled with respect to the orientation spaces. That is, the cavities are parallel to the locking edge.
  • the functional principle in the cavities is similar to a curved spring, namely, that the respective areas which are located at a greater distance from the central longitudinal axis of the spring, are displaced towards the center. This displacement process is particularly simplified if the material to be displaced spring does not encounter resistance. An open cavity thus simplifies the displaceability of the spring.

  • the metastable, state can be left by low forces.
  • the spring snaps back and bulges out new. Therefore, different large actuating forces are necessary to get from the stable to the metastable state and vice versa.
  • the bulge of the spring is to be equated with a laterally protruding projection on the spring, which is to be displaced similar to an arcuate spring. The projection is displaced until the spring abruptly jumps into the metastable position. This is the locking position.
  • the Verriegelungspösition By a crackling sound, as it occurs in spring made of metal or at least in bumps made of metal, the Verriegelungspösition is also acoustically determined. It also turns a slight jerk when the locking position is reached. The haptic information of the so-called clicker effect is a helpful feedback when laying and also when picking up the panels.
  • the spring is deformed during locking, it is provided that it is supported on a support surface of the opposite panel.
  • the support surfaces can run parallel to the laying plane. It is also conceivable that the support surface is inclined relative to the laying plane and causes a horizontal displacement of the spring behind the locking edge. It depends on the connection of the spring to the core also conceivable that the displacement of the spring takes place exclusively in the direction of the adjacent panel. This is for example the case when the spring is oriented perpendicular to the laying plane, that is, with its upper end facing towards the top of the panel and facing with its free lower end towards the bottom of the panel. The lower, free end can thus be pivoted in the direction of the laying plane. When the free end or the spring strikes a support surface inclined relative to the laying plane during locking, this causes the horizontal displacement of the free end of the spring behind the locking edge of the other panel.

Abstract

Revêtement composé de panneaux pouvant être reliés mécaniquement entre eux, lesdits panneaux (1, 2, 38) présentant des profils correspondants sur leurs côtés situés en regard les uns des autres, et pouvant se verrouiller mutuellement par l'intermédiaire de ces profils. Un élément ressort (11, 11a-f) est situé sur le noyau (15) des panneaux (1, 2, 38), et est déplaçable par un mouvement d'assemblage, pour se placer derrière un bord de verrouillage (17) sensiblement horizontal du panneau adjacent (1, 2, 38). Les panneaux (1, 2, 38) présentent une structure multicouche comprenant un noyau (15) en matériau élastique, à partir duquel l'élément ressort (11, 11a-f) est formée d'un seul tenant avec le noyau (15), dans le même matériau que ce dernier.
