Definitions

  • the present invention relates generally to improved floor boards and, more particularly, to a floor board for ondol floors, which is constructed so that adjacent floor boards are flexibly joined in a width direction thereof, and are coupled in a length direction thereof through horizontal snap coupling, thus increasing workability and reinforcing sound insulating capability.
  • Prefabricated floor boards having convex tongues and concave grooves at edges thereof, have been widely used. Since it is very easy to install the floor boards, this can be carried out by the average handy person. These floor boards are usually provided with a surface layer, such as lacquer or some kind of laminate.
  • An earlier patent disclosure dealing with the floor board is found in Korean Patent No. 394968, which was disclosed by the inventor of this invention and is titled “floor board for ondol floor or the like”.
  • the floor board of this patent is manufactured using unit boards. According to this patent, a side male fitting part and a side female fitting part are respectively provided on opposite side ends in a length direction of the floor board. Further, an end male fitting part and an end female fitting part are provided on opposite edges in a width direction of the floor board.
  • a synthetic rubber hot-melt adhesive is applied to a surface of the floor board, with a film separator being attached to the adhesive.
  • the side male fitting part of one floor board engages with the side female fitting part of an adjacent floor board which has previously been installed.
  • the end male fitting part of the floor board engages with the end female fitting part of an adjacent floor board which has previously been installed.
  • the hot-melt adhesive attached to a surface of the floor board adheres to a floor.
  • the present invention relates to the above-mentioned patent No. 394968. Further, Korean Patent Laid-Open Publication No. 2001-101827 has been proposed, which is titled “flooring material, comprising board shaped floor elements which are intended to be joined vertically”.
  • the flooring material of this document includes floor boards having a square, rectangular or rhomboidal shape.
  • the flooring material is characterized in that each floor board is provided with edges, a horizontal lower surface, and a decorative horizontal upper surface, and includes lower joining lips at two adjacent edges and upper joining lips at the two remaining edges.
  • the lower joining lips comprise vertical lower lip surfaces arranged parallel to the closest edge, the lower lip surfaces intended mainly to interact with vertical upper lip surfaces.
  • the joining lips are provided with horizontal locking surfaces, so that the flooring material includes recesses to limit vertical movement between two joined adjacent floor boards, and one or more heels intended to be snap joined to the recesses.
  • the cited inventions dealing with widthwise snap coupling have a structural problem of tongues and grooves, when a base floor board is joined to an adjacent floor board in a width direction.
  • physical friction inevitably occurs between the tongues and the grooves having angled shapes, so that the tongues and the grooves may be deformed during the widthwise coupling operation, and workability is considerably low.
  • a hook coupling method adapted to join floor boards together in a length direction is problematic in that, when the floor boards are installed on an uneven floor, a height difference may occur between the floor boards due to the unevenness of the floor.
  • the hot-melt adhesive applied to the lower surface of the floor board insufficiently absorbs vibration and noise, so that the sound insulating capability thereof is poor.
  • the inventor of the present invention makes attempts to improve the structure of the sides and edges of floor boards, thus affording easy installation, when a base floor board is joined to an adjacent floor board. As a result, the present invention is achieved.
  • an object of the present invention is to provide an improved floor board, which is manufactured using a board obtained by attaching decorative veneer, high pressure melamine (HPM), or low pressure melamine (LPM) to a base plate, for example, plywood, wood, a high density fiber board, or a particle board, and is constructed so that a hot-melt adhesive, containing synthetic rubber foam or polypropylene foam having enhanced restoring capacity such that the floor board is suitable for an ondol board with respect to thermal properties, is attached to a lower surface of the floor board, and a film separator is attached to the hot-melt adhesive so as to preserve its adhering capability.
  • HPM high pressure melamine
  • LPM low pressure melamine
  • a side female fitting part is provided at a side of a floor board in a length direction thereof, and has a downward recess.
  • the downward recess is downwardly curved in an arc form, and is upwardly inclined at a predetermined position of the arc.
  • an end male fitting part and an end female fitting part allowing snap coupling are provided on opposite edges in a width direction of the floor board.
  • a material having sound insulating or absorbing capability is used for the floor board of this invention, thus reducing noise.
  • This invention may also be employed for an ondol floor. Particularly, it is possible to join floor boards together through slanted snap coupling without changing the structure of the floor boards in a width direction thereof. Further, it is possible to join floor boards together in a length direction thereof through horizontal snap coupling.
  • the present invention provides a floor board, which is manufactured using a unit board obtained by integrally attaching decorative veneer, HPM, or LPM to upper and lower portions of a base plate, for example, plywood, wood, a high density fiber board, or a particle board through cold or hot pressing, and by subsequently cutting the attached board to a predetermined length and width.
  • a side male fitting part is provided at a side in a length direction of the floor board, and a side female fitting part is provided at the other side and has a downward recess which is downwardly curved in an arc form and is upwardly inclined at a predetermined position of the arc.

  • ‘width direction’ is defined as a short axis direction of the floor board.
  • ‘both sides’ or ‘both side ends’ are defined as both surfaces of the long axis of the floor board
  • ‘both end surfaces’ or ‘both edges’ are defined as both surfaces of the short axis of the floor board.
  • ‘length direction’ or ‘width direction’ are defined as the directions of respective surfaces that are at right angles to each other.
  • the side male fitting part and the side female fitting part provided on both sides flexibly secure floor boards in a width direction thereof, so that they may be continuously joined together.
  • the hot-melt adhesive attached to the lower surface of the floor board contacts a floor, thus allowing the floor boards to be easily joined together, while the floor boards are in close contact with each other.
  • the end male fitting part and the end female fitting part provided on both edges of the floor panel serve to join the floor boards in. a length direction thereof through snap coupling.
  • the foam hot-melt adhesive containing synthetic rubber as a main component is a solvent-free adhesive which is harmless to the human body. The adhesive functions to attach the floor board to a concrete floor having a relatively rough surface.
  • the adhesive serves to adapt the floor board made of wood to variation in the wood, for example, the contraction or expansion of wood due to heating conditions or variation in moisture content.
  • the hot-melt adhesive layer containing synthetic rubber foam absorbs or insulates noise generated during walking, thus providing enhanced sound absorbing capability and sound insulating capability.
