Description

    BACKGROUND OF THE INVENTION
  • [0001]
    1. Field of the Invention
  • [0002]
    The present invention related to a molding such as a floor strip such, a dilatation profile, a transition profile or a finishing profile.
  • [0003]
    The present invention also relates to a flooring material comprising board shaped floor elements which are joined vertically by means of separate assembly profiles.
  • [0004]
    2. Description of Related Art
  • [0005]
    It is previously known to produce different types of molding such as floor strips, metal strips, wood veneer coated strips and strips of homogeneous wood. There is a strong desire to bring about a floor strip with the same pattern as on a floor of thermosetting laminate. During the last years, these floors have become very usual. For instance, they are made with wood pattern, marble pattern and fantasy pattern. Possibly, you can use a homogeneous wood strip or a wood veneer coated strip for a few of the wood patterned floors. Previously known strips do not go well together with all the other floor patterns. The moldings most often comprise a thin decorative thermosetting laminate or a thermoplastic foil and a carrier which consist of a fibre board or a particle board. One problem with these moldings is that they do absorb moisture and, therefore, will expand, contract and warp with changes in moisture content. Joints between such moldings are inevitable and it is in these joints the effects of the expansion, contraction and warping is most noted.
  • [0006]
    Prefabricated floor panels which are provided with tongue and groove at the edges are well known today. As these are rather easy to install, this can be achieved by the average handy man. Such panels can be made of solid wood, particle board or fibre board. These floor panels are most often provided with a top surface, such as lacquer or some kind of laminate. The panels are often joined by being glued together via their tongue and groove. A version of this tongue and groove type of joint for panels is where the joint is provided with snap action which allows it to be joined without using glue. One such joint is known from WO 97/47834. In this publication the joint is constituted of an upper and lower cheek on the groove portion of the joint and a tongue on the tongue portion of the groove. The tongue is provided with a protrusion on the lower side and the groove is provided with a recess matching the position of the protrusion. The lower cheek is bent downwards during the insertion of the tongue and snaps back once the tongue and groove are in correct position. It is here essential that the force needed to bend the lower cheek is kept within predetermined parameters as great differences would either result in a mechanical lock which is too weak or that a too great amount is needed when joining the panels. This is normally not a problem when producing the panels from the same batch of panel core material. However when using panel core material from several different suppliers small deviations in panel thickness may occur. Such a deviation will inevitably result in problems with locking force and/or the force needed to assemble the panels.
  • SUMMARY OF THE INVENTION

  • [0025]
    FIG. 2 shows, in perspective view, a molding 1 which is provided with a first and a second distal edge 3 I and 3 II, respectively. The distal edges 3 I and 3 II, respectively, are provided with means for locking a first distal edge 3 I of a first molding 1 to the second distal edge 3 II of a second molding 1. The first edge 3 I is provided with one recess 34 while the second edge 3 II is also provided with at least one recess 34. The moldings 1 are connected to each other by means of a joining plate 40 having protrusions 41 matching the position of the recesses 34 of the first and second edges 3 I and 3 II, respectively. The recesses 34 are holes which are arranged on the rear side of the molding. The joining plate 40 is provided with holes for being attached to a wall. The joining plate 40 can hereby be used for attaching, at least the ends of the molding 1 to said wall. The holes are so arranged that one molding 1 can be attached to one end of the joining plate 40 while still allowing an installer to access one of the holes.
  • [0026]
    The protrusions 41 may be provided with hooks which are gripping walls of the recesses 34.
  • [0027]
    The rear side of the molding 1 is, according to the present invention, suitably provided with a longitudinal groove 35 which allows room for the joining plate 40. Edges 35 I of the groove 35 may further be provided with an undercut 36 (See, FIG. 4), while the joining plate 40 is provided with snapping edges 42 (See, FIG. 4).
  • [0028]
    According to the present invention, the interaction between the protrusions 41 and the recesses 34 will secure the distal edges 3 I and 3 II, respectively, of two adjacent moldings so that undesired gaps do not form between said moldings 1. The joining plate 40 is further designed to interact with the edges 35 so that the upper and lower surface of adjacent moldings 1 are flush when assembled. Finally, the interaction between the snapping edges 42 and the undercut 36 will ensure that the front face of adjacent moldings 1 are flush when assembled.
  • [0029]
    It is, according to the present invention, also possible to provide the joining plate 40 in the form of an angled joining plate for inner corners 40 I (See, FIG. 3 a) and an angled joining plate for outer corners 40 II (See, FIG. 3 b). The folding line may further be made so it is easy for the installer to adjust the angle in case the corner is not at straight angle. The protrusions 41 for the angled plate for inner corners 40 I are either angled or resilient to make assembly possible.
  • [0030]
    It is known that moldings 1, like the ones described in the invention, have to be cut at some point or another. It is also known that such moldings have to be proved with a mitre at corners. It will, in these cases, be necessary for the installer to drill new recesses 34. It is, therefore, suitable to use a template or a jig to ensure that these new recesses are correctly placed. Such templates or jigs may be delivered together with, or as an accessory to, the molding 1 and joining plate 40 system. It is also possible to design the joining plate 40 in such a way that it may double as a drilling template by arranging holes and/or providing it with guiding notches.

    Accordingly, FIG. 5 a-5 b shows in cross-section a joint 101 constituted for locking between panels according to a first embodiment of the invention. FIG. 5 a shows the joint 101 where a first type of panel material has been used. FIG. 5 b shows the joint 101 when a second panel material has been used. The thickness of the panels deviates as they are manufactured by different suppliers. The joint 101 is constituted for mechanical locking between panels where the panels are joined by turning or by horizontally pushing the panels together. The joint 101 have a first edge 101 I and a second edge 101 II. The panel have an upper side 103 and a lower side 104. The first edge 101 I have a lower cheek 102 which lower cheek 102 has an outermost portion 102 I and an innermost portion 102 II. A groove 105 is present on the lower side 104 of the panel. The groove 105 is arranged in a position between the innermost portion 102 II and the outermost portion 102 I. The innermost position 102 II is the area where at least some flexing of the lower cheek 102 will occur. The groove 105 or portions of the groove 105 may therefore be arranged on a position further from outermost portion 102 I of the lower cheek 102 than the innermost face of a panel groove 120. A base portion 105 I of the groove 105 is located at a predetermined distance L from the upper side 103. The core material of the panel is made of medium density fibre board.

The position of the upper face recess 102 U and the protrusion 111 are arranged on matching positions.
  • [0032]
    The panels includes a core which is covered with an upper decorative surface layer. The core is most often constituted of saw dust, fibre or particles of wood which are bonded together with glue or resin. Since the cellulose based material in the core is sensitive to moisture, it is advantageous to coat the surface closest to the joint if the floor will be exposed to moisture. This surface treatment may include wax, resin or some kind of lacquer. It is not necessary to coat the joint when the floor boards are to be glued together since the glue itself will protect from penetration of moisture. The upper decorative surface may be constituted by a decorative paper impregnated with melamine-formaldehyde resin. One or more layers of so-called overlay paper made of α-cellulose which are impregnated with melamine-formaldehyde resin are advantageously placed on top of the decorative paper. One or more of the layers may be sprinkled with hard particles, of for example, aluminium oxide, silicon oxide or silicon carbide in connection to the impregnation in order to improve the abrasion resistance. It is also possible to provide the upper surface with a decor which is protected by a layer of UV curing lacquer which may comprise hard particles for further abrasion resistance. The lower side may be surface treated with lacquer or a surface layer of paper and resin.
  • [0033]
