Definitions

  • the present invention refers to a system for joining panels or boards used in particular for prefinished wood floors.
  • the invention also extends to panels of other woody materials such as laminates, plywood, multilayer wood, MDF and the like, provided they have adequate elasticity. Furthermore, even if specific reference is made herein to wood or parquet floors, and the terms horizontal and vertical refer to this situation, the invention also extends to wood coverings for vertical or slanting walls.
  • Panel joining systems are currently known to the art based on coupling of a male element and a female element.
  • the male part generally has a profile with parallel edges and the female part has a matching slot. Consequently the male part of a panel can engage by tonguing inside the female part of another panel.
  • the object of the present invention is to overcome the drawbacks of the prior art by providing a panel joining system adapted to simplify assembly operations and reduce effort by the operator during said operation.
  • Another object of the present invention is to provide such a panel joining system that is able to ensure a good tightness of the joint.
  • the panel joining system provides for the use of a panel comprising a male part provided on at least one side of the panel and a female part provided on at least one other side of the panel.
  • the male part comprises a protrusion or rib, with a slightly smaller thickness compared with the thickness of the panel, protruding outwardly from the respective side edge of the panel along a plane substantially parallel to the plane of the panel.
  • This male protrusion has an incision along a plane substantially parallel to the plane of the panel, so as to define two substantially flexible tongues in a transverse direction. At least one of these tongues has at its end a tooth or thickening.
  • the female part comprises a groove formed in the thickness of the respective side of the panel, along a plane substantially parallel to the plane of the panel. This groove is able to receive the male protruding part of another panel and has an entry narrowing able to be passed by said at least one tooth of the protruding male part.
  • FIGS 1, 2 and 3 a wood panel according to the invention, denoted as a whole with reference numeral 1, is illustrated.
  • the panel 1 by way of example, is substantially rectangular in shape, but can be of another shape, such as square, triangular and the like.
  • a protruding male part 2 and a recessed female part 3 are formed on the two opposite major sides (section A-A of Fig. 3) of the panel 1; a protruding male part 2 and a recessed female part 3 are also formed on the opposite minor sides (section B-B of Fig. 3) of panel 1.
  • the male part 2 is shaped as a protrusion or rib with a linear profile that protrudes outwardly from the respective side edge of the panel 1, along a horizontal plane parallel to the plane of the panel.
  • the female part 3 is shaped as a groove formed, along a horizontal plane, in the respective side edge of the panel 1.
  • the male part 2 is substantially L-shaped and extends for a good part of the length of the two adjacent sides of the panel 1, leaving free two end portions 11 (Fig. 3) of said adjacent sides of the panel 1.
  • the female part 3 also is substantially L-shaped and extends for the entire length of the other two adjacent sides of the panel 1.
  • the male protrusion 2 has a smaller thickness than the total thickness of the panel 1 and is disposed approximately on the midline with respect to the horizontal axis of the thickness of the panel 1.
  • a cut 20 is formed in the male protrusion 2 along a horizontal plane, approximately along the midline axis of the thickness of the male protrusion 2.
  • the cut 20 extends for the entire protrusion 2 and also involves part of the thickness of the panel 1.
  • the cut 20 can extend into the thickness of the panel 1 even for a portion equal to roughly the width of the protrusion 2.
  • the cut 20 divides the male protrusion 2 into two tongues 21, 22 having a suitably reduced thickness so as to be elastically flexible so as to be able to bend elastically in a vertical direction.
  • the lower tongue 22 can have a smaller thickness than the upper tongue 21 and thus greater elasticity.
  • each tongue 21, 22 there is provided a respective thickening or outwardly protruding tooth 23, 24 which extends for the entire length of the tongue.
  • the teeth 23, 24 protrude upwards and downwards, respectively, from the respective upper and lower tongues 21, 22 so as to give rise to respective abutment surfaces 25, 26 which can be step-shaped or in the form of inclined planes.
  • the ends 27, 28 of the teeth 23, 24 are suitably chamfered or rounded.
  • the female part 3 has a recessed seat or groove 30 formed, along a horizontal plane, in the thickness of the panel 1, approximately along the midline axis of the thickness of the panel 1, in any case positioned in such a way that when the male is housed therein, the surfaces of the adjacent panels are aligned.
  • the female seat 30 has a width suitable to receive the thickness of the male protrusion 2 and the depth of the seat 30 is greater than the width of the male protrusion 2.
  • the recessed seat 30 is defined between an upper potion 31 and a lower portion 32 of the thickness of the side of the panel 1.
  • the upper and lower portions 32, 32 have in their inside surface respective inwardly protruding edges 33, 34 which extend along the entire length of the seat 30.
  • edges 33, 34 define a narrowing at the entry to the seat 30 and respective abutment surfaces 35, 36, step-shaped or in the form of inclined planes, in the upper and lower portions 31, 32 which delimit a wider part at the bottom of the seat.
  • the inside end comers 37 and 38 of the upper and lower portions 31, 32 are suitably tapered or rounded.
  • Figure 5 illustrates a second embodiment of a panel 1 according to the invention, wherein like reference numerals are used to denote like or corresponding parts to those of the first embodiment.
  • the tooth of the upper tongue 21 of the male and the corresponding edge of the upper portion 31 of the female have been eliminated.
  • the tooth and the corresponding edge may also be provided only in the upper tongue 21 of the male and in the upper part 31 of the female, respectively.
  • Figure 6 illustrates the joint between two panels 1, 1' according to the second embodiment.
  • the two panels 1, 1' are positioned on a flat surface, such as a floor, so as to have the female part 3 of the panel 1' facing the male part 2 of the panel 1.
  • the panel 1' is moved towards the panel 1.
  • the rounded parts 27, 28 of the tongues 21, 22 of the male 2 come into contact with the rounded parts 37, 38 of the upper and lower portions 31, 32 of the female which act as a lead-in, so as to bring about inward bending of the tongues 21, 22 of the male.
