Definitions

  • the invention relates to a covering of mechanically interconnectable panels.
  • Wall, ceiling and floor coverings such as prefinished parquet, real wood floors or laminate flooring, consist of several rows of predominantly rectangular panels in their configuration.
  • the panels have on a longitudinal side and on a head side continuous grooves and on the respective opposite longitudinal side or head side continuous springs, which are adapted to the grooves form-fitting manner. By connecting tongue and groove the panels are laid, the panels of the second adjacent rows are offset from one another.
  • This game is preferably as small as possible so that it does not come to a height offset in the area of the butt joint of two panels. Due to the principle, however, a particular game can not be avoided.
  • the invention is based on the object to show a covering of mechanically interconnectable panels, in particular a floor covering, wherein the height offset in the region of the butt joint is minimal.
  • the panels of the flooring according to the invention are intended and adapted to be mechanically connected to other similar panels.
  • the connection is made via arranged on the complementary sides of the panels connecting elements in the form of tongue and groove joints.
  • the adjacent panels each have a horizontal groove on their mutually complementary sides.
  • a relative to the panel at least in parts relatively displaceable spring is arranged.
  • the spring engages in connecting the adjacent panels in a groove of the adjacent panel, thus blocking the adjacent panels against vertical displacement against each other.
  • the spring has a holding portion which is disposed in the groove of the spring-holding panel.
  • the spring has at least one projection.
  • the projection projects transversely to the laying plane, ie in the direction of the top or bottom of the panels.
  • a projection is given when the projecting portion of the spring is wider than the groove width measured in the region of the projection transversely to the laying plane the locking position.
  • the projection therefore projects in particular in relation to the holding section of the spring, which is matched to the groove width.
  • the grooves preferably horizontal, i. in laying level, are oriented. But it is also possible, the grooves and thus the springs inclined, i. at an acute angle to the laying level.
  • the grooves each have different long upper and lower groove cheeks, so that opposite to the shorter groove cheeks protruding portions of the longer groove cheeks in parallel spaced from each other.
  • These projecting portions of the groove cheeks serve as support surfaces for the projection.
  • the projection is intended, when in contact with this projecting portion of the groove cheek, transversely to the laying plane, i. usually to be displaced perpendicular to the laying plane of the panels.
  • the projection or the projecting portion of the spring is not only pushed back in the vertical direction and reduced to the width of the groove between the opposite projecting portions of the longer groove cheeks, but at the same time still in the laying plane, i. shifted horizontally.
  • the horizontal displacement results from the fact that the projection is an integral part of the spring, which is already supported with its one end in the groove, but is configured so that the other end of the spring is displaced in the direction of the laying plane.
  • the projection is thus in operative connection with a locking portion of the spring, which is displaceable by the movement of the projection in the direction of the groove of the adjacent panel.
  • groove cheeks in the context of the invention, not only the region is to be understood, which extends between the immediately opposite groove cheeks. It also includes the area that faces the long groove cheek, as this space is also occupied by the spring.
  • the groove cheeks in particular the longer groove cheeks, can vary in their distance considered over the groove depth.
  • protruding areas of the longer groove cheeks can be set off or offset from the shorter groove cheeks, so that the distance to the enlarged opposite groove cheek. Nevertheless, the remote areas also count to the groove.
  • the holding portion is connected via a connecting portion with the locking portion.
  • the connecting section is preferably connected to the holding section via a hinge arranged on its edge pointing to the top or to the underside of the panel.
  • the locking portion is coupled via a arranged at its diagonally opposite edge joint with the connecting portion. The position of this joint significantly determines the position of the most prominent point of the projection.
  • the spring is at least partially folded before joining two panels in a starting position, said holding portion, connecting portion and locking portion are pivoted about the joints against each other in the vertical direction from the plane of the holding portion out.
  • mutually facing side surfaces of the holding section, connecting section and locking section are each bevelled in a complementary manner to the top and bottom of the panels.
  • the projection When connecting two adjacent panels of the projection is displaced by the approach of the longer groove cheeks of the panels.
  • the projection can point up or down.
  • the projection is displaced by contact with a lower groove cheek of the groove receiving the locking portion of the first panel.
  • the vertical movement results in a horizontal movement in which the projection on the lower groove cheek slides along the groove receiving the locking portion.
  • This requires a pivoting of the connecting portion about both joints in the horizontal plane of the holding portion.
  • the locking portion is pivoted about the hinge of the projection in the horizontal plane of the holding portion.
  • the spring is stretched out of its folded state as soon as the longer groove flanks have approximated as far as possible. This is the case when the height offset between adjacent panels is minimal.
  • the locking portion is formed by the stretching movement of the spring in the groove of the pressed first panel.
  • a groove facing end surface of the connecting portion may be chamfered or rounded.
  • the hinge between the locking portion and the connecting portion at the level of the lower groove cheek of the locking portion receiving groove is preferably aligned horizontally after connecting two adjacent panels. Since the lower groove cheek of the spring-retaining groove extends only over a width of the holding portion, the surfaces of connecting portion and locking portion facing the underside of the panel rest on a lower groove cheek of the groove receiving the locking portion of the spring.
  • a material of lower elasticity is used, as in the joints, or the connecting portion.
  • the spring can have further sections in addition to the holding section, the connecting section and the locking section.
  • a projection is coupled to a specific mechanism.
  • This mechanism causes a locking portion of the spring is pressed in the horizontal direction in the groove of the adjacent panel.
  • the mechanism is triggered as soon as the projection comes into contact with a corresponding groove cheek and is displaced in the direction of the other groove flank.
  • the specific design of the spring also depends on the laying method. in particular, when a panel is not to be stored in a parallel, linear movement, but should be quasi angled by a pivoting movement. During the pivoting movement, the projecting areas of the longer groove flanks approach the length of the groove approached at a certain time to different degrees. Example: In a 45 ° position, the groove flanks at one end of the groove are almost at the end position, while the groove flanks at the other end are at a distance of several centimeters. In particular, in this case, it is expedient to provide either a plurality of spaced-apart springs, which do not hinder in their kinematics.
  • a spring which is divided by transverse to the groove slots in independently operable spring segments.
  • the spring segments preferably have a common holding section. This configuration can be called comb-like. This embodiment proves to be particularly advantageous when the second panel, starting at one end of the groove, is lowered in the longitudinal direction of the groove, so that the spring sections engage one after the other in the groove of the first panel.
  • Independently actuable spring segments can also be used in every other type of laying, i. even if the panels are not pivoted to each other, but are stored in a parallel movement.
  • the locking portion may have a profiling on its side facing the upper and / or lower groove cheek side surface.
  • the connecting portion may as well as the locking portion have a profiling on one or both side surfaces. This profiling may, for example, be wavy, have individual points or a sawtooth profile.
  • the groove cheeks of the panels can have a profiling complementary to profiling. It is also possible to provide on one or both side surfaces of the locking portion locking elements which engage in insertion of the locking portion in the groove of the adjacent panel in corresponding recesses of the upper or lower groove cheek.
  • the locking section bridges the gap adjoining the shorter groove cheek to the adjacent longer groove cheek of the other groove in order to minimize the height offset in the region of the butt joint of the panels.
  • the locking portion must therefore partially protrude from the groove receiving it, that is over the shorter groove cheek this groove.
  • the spring can extend over the entire length of the groove.
  • a plurality of springs can be provided in the longitudinal direction of the groove at a distance from each other. These may have independently operable locking portions.
  • panels can also be offset from each other in the longitudinal direction of the groove. It is conceivable to connect the holding portions in the region of the groove with each other, wherein the compound can be used simultaneously as a spacer between the springs.
  • a locking strip which serves to secure the adjacent panels against tensile stress in a laying plane.
  • the locking bar thus serves to couple the panels in the laying plane, while the springs are intended to prevent the panels from shifting relative to one another in the vertical direction. Since the locking strip which engages under the adjacent panel, is arranged at a relatively large distance from the top of the panels, it is additionally provided that the attacked by the locking bar panel is primarily supported on a support strip. This is arranged at a greater distance from the locking bar than the groove. In other words, the groove is between the support bar and the locking bar.
  • the support bar has the function of reducing the distance of the support point from the top of the panels, which is particularly advantageous for very thin-walled and softer materials.
  • the spring can consist of a uniform material.
  • Correspondingly thin areas can serve as film hinges. The thicker areas then serve to accommodate the forces acting transversely to the laying plane.
  • the material for the spring may be both a wood material, that is, it may be wood or a material containing wood fibers, or a material that is made of wood as a base material, such as liquid wood.
  • Metal and metal alloys, e.g. Spring steels are also suitable for the springs as well as composites.
  • the use of bimetallic or mixed plastics is just as possible as the use of materials based on thermoplastic or thermosetting plastics.
  • the spring can also consist of a fiber-reinforced plastic.
  • the spring is elastic.
  • the spring may be designed to be biased prior to connection. Due to the bias of the locking portion is pressed into the groove of the adjacent panel and additionally secured the connection of two panels.
  • Springs with restoring forces due to elasticity or because e.g. a spring steel was used, are suitable to retract the spring after opening the connection back to the starting position or jump back.
  • the joints connecting portions of the spring are preferably made of the same material as the spring.
  • a different material for this purpose, for example a kind of hotmelt.
  • Hotmelt is to be understood as meaning hotmelt or hotmelt adhesives which are based, for example, on polymers, resins or waxes and still have a flexibility after cooling. The basic idea is based on a functional separation of elastic and non-elastic areas.
  • a special feature are springs, which can assume two states.
  • the spring can assume a stable position and a metastable position, from which the spring automatically returns to the stable state upon termination of the force.
  • a bistable spring can be provided, which is characterized by the fact that two stable positions exist and every change from one position to another requires a force.
  • the spring with a metastable position is transferred from the stable position to a metastable position by the process of buckling, the restoring force being much less from the metastable position to the stable position than vice versa.
  • This favorable force-displacement characteristic can also be utilized in the present invention.
  • the bulge is equivalent to a projection on the spring, which is to be relocated. The projection is displaced until the spring jumps abruptly into the metastable position. This is the locking position.
  • the locking position is also audible. But it also turns a slight jerk when the locking position is reached.
  • the haptic information as well as an acoustic information of the so-called clicker effect are helpful feedback when laying and also when picking up the panels.
  • the clicker effect primarily occurs with metallic materials.
  • the principle is also compatible with other bulking materials, such as e.g. Plastics feasible.
  • the material of the panels there is no restriction with regard to the material of the panels, as long as this can be brought into the necessary form, in particular by machining.
  • These can be panels based on wood-based materials or plastics, as well as mineral materials and composite materials.
  • the size of the panels also plays a minor role.
  • the panels may also be large in size, e.g. as component plates of 600 mm x 1500 mm.
  • the inventive concept is particularly applicable to all floor systems in which an upper covering is arranged on a support, such as real wood coverings, laminate, support with painted surfaces as top coat, linoleum, cork on support plates, etc.
  • the cover layer may in particular consist of a decorative paper with overlay , which determines the appearance of the element plate.
  • a floor covering may thus be a parquet floor, a finished parquet floor, a real wood floor or a laminate floor.
  • the floor covering may in particular also be a raised floor or a hollow floor in which below the covering, i. below the panels is a cavity that is used for the wiring.
  • below the covering i. below the panels is a cavity that is used for the wiring.
  • said springs can be provided not only on head sides but also on longitudinal sides of a panel, it is possible to provide individual panels e.g. Lift again by a siphon and then put it down again.
