Definitions

  • the present invention generally relates to a floorboard, such as e.g. a laminate panel, a parquet element, a veneer floor element, a ready-to-lay parquet element or the like.
  • a floorboard such as e.g. a laminate panel, a parquet element, a veneer floor element, a ready-to-lay parquet element or the like.
  • a floorboard such as e.g. a parquet element for a parquet floor generally has a rectangular shape and comprises a supporting plate made of wood material provided on at least one face with a covering.
  • the floorboard has a first edge provided with a tongue, and an opposite, second edge provided with a groove, the tongue and groove fitting into corresponding grooves and tongues of further similar floorboards.
  • Tongues and grooves have a rectangular profile and are configured in such a way that tongues fit into grooves, almost without play, after glue has been applied.
  • the object of the present invention is to provide a floorboard, which can be more easily assembled and which allows for a more efficient gluing. This object is achieved by a floorboard as claimed in claim 1.
  • a floorboard according to the present invention has a first edge with a tongue and an opposite, second edge with a groove, the tongue and groove fitting into corresponding grooves and tongues of further similar floorboards.
  • the groove has a stepped profile, which is configured so that the back end of the groove is narrower than its entrance.
  • the tongue has a stepped profile substantially matching that of the groove.
  • tongue and groove have matching profiles
  • the front part of the tongue is narrower than the entrance of the groove, and can thus more easily be engaged therein.
  • the front part of the tongue will reach the part of the groove that dimensionally matches this front part.
  • This easier engagement of the tongue into the groove shall reduce the time needed for laying the flooring by up to 20%.
  • the glue applied at the entrance of the groove will first be spread on this narrower, front end of the tongue, before being squeezed out between the matching parts of groove and tongue.
  • the glue is not any more pushed towards the back of the groove but is spread on larger surfaces of the tongue and groove joint, so that an improved gluing efficiency is obtained.
  • the tongue is formed as two rectangular portions.
  • a first portion is adjacent the first edge of the floorboard and a second portion further protrudes from the first portion, the first portion being thicker than the second portion.
  • the groove comprises two consecutive rectangular sections, a first section forming the entrance of the groove and a narrower, second section forming the back end of the groove. Assembly of such a floorboard with a similar floorboard is thus facilitated by the larger entrance of the groove, but precise guidance is still obtained as the front end (i.e. the second portion) of the groove reaches the matching, back end (i.e. the second section) of the groove.
  • Tongue and groove profiles are preferably configured in such a way that upon assembly, a small clearance remains between tongue and groove at the level of the junction between the first and second sections of the groove. This provides for possible variations in manufacturing tolerances, which could otherwise prevent an intimate contact between two adjacent floorboards. In addition, glue may collect in this clearance.
  • the tongue is shorter than the groove, so as to provide a free space for surplus glue towards the back of the groove.
  • An undercut is preferably provided above the groove, respectively the tongue.
  • a floorboard conventionally has a generally rectangular shape.
  • the tongue shall thus extend along a longitudinal edge of the floorboard and the groove shall extend along the opposite longitudinal edge thereof.
  • the tongue may extend along a transverse edge of the floorboard and the groove along the opposite transverse edge of the floorboard.
  • the floorboard shall generally comprise a supporting layer provided on one face with a covering layer, the tongue and groove being arranged on the edges of this supporting layer.
  • the floorboard may further include a lower layer on the face of the support layer opposed to the covering layer.
  • Each floorboard 10 in accordance with a preferred embodiment of the present invention are partially shown in cross-section in the drawings.
  • Each floorboard 10 conventionally has a generally rectangular shape and comprises e.g. three layers of wood or wood derived material, which are glued to one another.
  • the upper layer 12 may be made of oak
  • the middle layer 14, hereinafter called support layer may consist of battened wood
  • the lower layer 16 may consist of battened wood or plywood.
  • each floorboard has at one longitudinal edge a continuous groove 18 provided in the support layer 14. It will be appreciated that the groove has a stepped profile, as can be seen in Fig.1.
  • the groove 18 comprises a first rectangular section 20 forming the entrance of the groove 18, and a consecutive, second section 22 forming the back end of the groove 18.
  • the width of the second section 22, indicated w in Fig. 1, is narrower than that of the first section 20.
  • These two rectangular sections 20 and 22 are preferably centrally aligned with each other along a plane parallel to the upper surface 23 of the floorboard 10.
  • each floorboard is provided with a tongue 24 protruding from the support layer 14, in a direction perpendicular to the upper surface 23 of the floorboard 10.
  • the tongue 24 also has a stepped profile, which substantially matches that of the groove 18.
  • the tongue 24 is formed as two rectangular portions. A first portion 26 is adjacent the second edge of the floorboard and a second portion 28 further protrudes from the first portion 26. The two portions 26, 28 are centrally aligned along a plane parallel to the upper surface 23 of the floorboard 10.
  • the front end of the tongue 24, i.e. the second portion 28 has a thickness matching the width of the second section 22 of the groove 18, and the thickness of the first portion 26 of the tongue 24 matches the width of the entrance of the groove 18.
  • glue is preferably applied e.g. at the entrance of the groove 18, but it may also be applied, alternatively or in addition, on the tongue 24.
  • the entrance of the groove 18 is narrower than the front end (i.e. the second portion 28) of the tongue 24, the latter can easily be engaged into the groove 18.
  • the first portion reaches the back end of the groove 18 and is guided in the narrower, second section 22.
  • the glue applied at the groove entrance will first be spread on this narrower, front end of the tongue 24 before being squeezed out between the matching parts of groove 18 and tongue 24.
  • the glue is spread on large surfaces of the tongue 24 and groove 18, so that an improved gluing efficiency is obtained.
  • the tongue-and-groove joint is preferably configured in such a way that upon assembly, a small clearance 46 remains between tongue 24 and groove 18 at the level of the junction between the first 20 and second 22 sections of the groove 18. This provides for possible variations in manufacturing tolerances, which could otherwise prevent an intimate contact between two adjacent floorboards. In addition, surplus glue may collect in this clearance.
  • the tongue 24 is preferably shorter than the groove 18, so as to provide a free space 48 for surplus glue.
