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 continuous grooves on one longitudinal side and on one side of the head and springs that pass through on the opposite longitudinal side or head side and are adapted to the grooves in a form-fitting manner.
  • tongue and groove By connecting tongue and groove the panels are laid, the panels of the second adjacent rows are offset from one another.
  • the movement of the locking spring is not hindered.
  • a friction action between the locking spring and locking groove when extending the locking spring should be reduced or avoided altogether, to ensure that the locking spring extends as intended.
  • the play in the end position of the locking spring should be as minimal as possible, so that the respective adjacent panels are connected without height offset.
  • the invention relates to a covering of mechanically connectable with each other in a laying plane panels.
  • the inventive idea is applicable to all floor systems in which a plurality of panels are mechanically connectable to a covering, such as those with a visible topping and an underlying support is arranged, such as real wood flooring and laminate, such as carriers with painted surfaces as a topping such as linoleum, cork on carrier 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 can thus be a parquet floor, a finished parquet floor, a real wood floor or a laminate floor.
  • the panels connectable to a covering have the following characteristics.
  • Adjacent first and second panels have mutually largely complementary, mutually facing end faces, for example, on the narrow sides and / or on the long sides on "end face” means both from the support surface and the visible surface (optionally Begeh reaction) facing away, for the contact with the contact
  • In the end face of the first panel opens a guide groove and in the end face of the second panel opens a Verrieglungsnut.
  • the panel typically has a relatively small thickness of 8 mm to 10 mm.
  • a locking spring Arranged in the guide groove of the first panel is a locking spring which is displaceable relative to the guide groove and which is adapted to engage in the locking groove of the adjacent panel when connecting the adjacent panels in order to adopt a locking position in order to fix the panels in the direction perpendicular to the laying plane.
  • the locking spring is preferably designed as a flat strip to stress in the comparatively thin end face little space.
  • the material for the locking 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 are just as suitable for the springs as composite materials.
  • the use of bimetallic or mixed plastics is just as possible as the
  • the spring can also consist of a fiber-reinforced plastic.
  • the locking spring is produced by injection molding.
  • the locking spring extends for example over more than 60%, preferably over more than 80%, of the extent of the associated edge of the panel.
  • the locking position in the sense of the invention causes, as already mentioned, that the two panels are fixed relative to each other at least in the direction perpendicular to the laying plane except for a possibly unavoidable game.
  • a guide groove is incorporated, into which the locking spring is inserted.
  • the locking spring is movably mounted in the guide spring.
  • the direction of movement of the locking spring has at least one vector component which is parallel to the laying plane. For example, the direction of movement is parallel to the laying plane.
  • the direction of movement is inclined to the laying plane, more preferably, the direction of movement is inclined upwards, so chosen so that the locking spring approaches the visible surface of the covering during movement into the locking position.
  • the angle between the direction of movement and the laying plane is in the range of 5 ° to 15 °, more preferably in the range of 9 ° to 13 °, most preferably in the range of 10 ° to 12 °.
  • a lower cheek of the locking groove is formed such that it has an outer contact edge for lateral contact of the locking spring in its locking position and a respect to the Bermmante inner, a clear distance to the locking spring in the locking position completing section up.
  • lower cheek means the cheek of the locking groove nearest the bearing surface of the pad.
  • Outer touching edge means an upstream portion of the cheek, followed by an “inner” portion behind the touching edge, if the course of the cheek of
  • the term “contact edge” is merely intended to imply that a contact between the cheek and the locking spring is desired.
  • the contact edge thus defines the region of the cheek, which reaches at least the highest approximation between the cheek and locking spring in its locking position. According to the invention, however, it is preferable to achieve a touch. Due to the embodiment of the invention, on the one hand, the friction is minimized compared to an extended contact surface between the locking spring and locking groove.
  • the pre-storage according to the invention of the contact edge which is offset, for example, immediately below the abutting edge of the two connected panels to a maximum of 2 mm from the vertical projection of the abutting edge, ensures that the negative effect of the possible bending of the locking spring due to the system-related game in the Guide groove is minimized to the height offset, provided that the contact edge essentially determines the height orientation.
  • the inventive design reduces the friction and thus ensures reliable locking, at the same time the precision of the mutual alignment of the first and second panel is improved or at least not endangered.
  • the locking spring touches the locking groove in its locking position at other locations.
  • the touch occurs at the top, i. next to the visible surface, cheek and / or in the area of the groove bottom.
  • the contact takes place, for example, in the form of a vertical impact, that is to say largely without influencing the orientation of the locking spring in the generally clearance-like receptacle in the guide groove.
  • contact takes place exclusively at the contact edge between the locking spring and the locking groove in the locking position of the locking spring.
  • the front Bermmante and the inner clear distance between the two locking partners of locking spring and Locking groove achieved in that the lower cheek and the cheek-facing surface of the locking spring are flat and the two planes defined by the surfaces are inclined to each other.
  • the locking spring has a bevel on its front edge facing in the locking position of the lower cheek of the locking groove. This can be prepared by a relatively simple processing step, the inner clear distance between the locking spring and the locking groove or optionally increased by this measure.
  • this embodiment ensures that the contact between contact edge and locking spring is made comparatively late, for example, only when reaching the locking position. As a result, the friction during the locking movement of the locking spring is prevented.
  • the contact edge is formed as extending along the groove elevation of the cheek in this.
  • the locking groove widens toward its groove mouth in order to minimize touch or friction during "retraction" of the locking spring.
  • the upper cheek of the locking groove defines a plane inclined to the laying plane to avoid contact between the upper cheek of the locking groove and the upper flank of the locking spring.
  • the contact edge in the plane defined by the lower cheek of the guide plane is according to another embodiment, the contact edge in the plane defined by the lower cheek of the guide plane.
  • a clear distance to the locking spring in the locking position compliant portion is at least partially below the plane defined by the lower cheek of the guide groove to minimize friction even when due to the game easily angled in the guide groove locking spring ,
  • a clear distance to the locking spring in the locking position compliant portion is concavely curved.
  • a locking strip which engages under the adjacent panel and which is suitable for securing adjacent panels against tensile loads in a laying plane is also provided on one of the mutually complementary end faces.
  • the locking bar is formed on the first panel.
  • the panel holding the locking spring thus has a locking strip which engages under the adjacent panel and which is suitable for securing adjacent panels against tensile stress in a laying plane.
  • the locking strips thus serve to couple the panels in the laying plane, while the locking springs prevent the panels from displacing relative to one another in the vertical direction perpendicular to the laying plane.
  • the attacked by the locking bar panel is supported on the locking bar.
  • the clear width of the guide groove, in which the locking spring is displaceable at the narrowest point more than the 1, 05-fold, preferably 1, 1 times the maximum strength of the locking spring.

  • means for resilient bias of the locking spring are provided in the locking position.
  • the means for elastic bias are formed integrally with the locking spring. It can be provided on the locking spring elastically resilient projections.
  • the means are based for example on the bottom of the guide from. It is advantageous if the locking spring is biased in the locking position, so that it urges in the installed position horizontally or at least with a horizontal component of movement in the locking groove. As a result, the panels are held automatically on impact.
  • the locking spring on its upper side, ie the visible surface of the pad facing side, a front bevel, so when connecting, for example, when swiveling down or purely transverse lowering of the second panel and the ramp-like emergence on the resulting by the bevel oblique surface the locking spring, the locking spring can be urged out of the locking position and then to lock with the locking groove.
  • the transition from the inner, a clearance to the locking spring in their locking position compliant portion of the locking groove towards the bottom, so the deepest point of the locking groove is formed so that instead of a vertical impact the locking spring
  • the transition area is defined by a chamfer of the cheek or the floor or it is concavely curved.
  • the purpose of such a ramp is that the locking spring is urged upon contact of the transition region against its upper cheek of the guide groove and thus the play of the locking spring, which would be present in the free locking spring, is reduced in the locking position. A height offset between the two panels can thus be prevented.
