Definitions

  • the present disclosure relates to methods and fasteners for attaching boards or planks to a support structure.
  • a number of planks or boards which for instance may be formed from wood, plastic or a wood-plastic composite material, may be installed substantially parallel to each other to substantially form a surface.
  • the attachment system for attaching boards or planks may be used to form for instance floors, especially outdoor decks, floor coverings or floor claddings, walls, for instance fences, wall coverings or cladding, ceiling claddings, etc.
  • WO 2006/011 173 A1 discloses a wooden floor laying system comprising fasteners (supports 3) to be attached to parallel joists (base supports 1), wherein upper sides of said fasteners are provided with snap-fit connectors (two end tabs 5 and two central tabs 6) having, when seen in a direction in line with the boards (boards 9) to be attached, a substantially V-shaped cross-section, wherein a first leg of the V-shape forms an upwardly extending wall and the second leg of the V is slanted downwards from the upper end of said wall and is free at its outer end to be clipped into a respective half-dovetail groove provided in the lower or lateral side of the board, which groove extends in the length direction of said board.
  • the respective snap-fit connector (projecting part 8) comprises an upwardly extending central wall (full tongue 8a) provided with harpoon-shaped tenons (10) which are oriented obliquely away from the central wall (8a) in the direction of the base (6, 7) and which tenons (10) are elastically deformable such as to temporarily flex towards said central wall (8a) about a virtual axis extending in the longitudinal direction of the dovetail groove.
  • snap-fit attachment systems which have boards with pre formed grooves to be clipped onto fasteners having snap-fit connectors
  • such snap-fit attachment systems still have serious drawbacks.
  • the snap-fit connectors may prevent the boards from being lifted after being clipped onto the respective fasteners, the boards may accidentally be pushed out of place in the longitudinal direction of the boards, which can be very dangerous, for instance in case of a high level deck.
  • it can be an object of the invention to provide a board or plank fastener and/or a board or plank attachment system, wherein at least one of the disadvantages of the prior art fasteners or systems is counteracted.
  • it can be an object of the invention to provide a fastener which on the one hand incorporates one or more advantages of known snap-fit attachment systems, e.g. no visible screw heads, and which on the other hand counteracts at least one of the disadvantages of the above mentioned snap-fit attachment systems.
  • the present disclosure may aim at providing a method, system and/or fastener for snap-fitting attachment of planks or boards, which method, system and/or fastener may counteract that the installed boards or planks can be accidentally pushed out of position.
  • the present disclosure provides for a fastener for attaching a board or plank to a support structure, in particular in order to form a deck or the like including multiple juxtaposed boards or planks, said fastener comprising a base portion and at least one snap-fit connector for interlockingly engaging a corresponding snap-fit element, in particular an elongate slot or recess, more in particular a dovetail groove, of the board or plank, wherein said snap-fit connector includes a support member protruding from the base portion in a substantially upward direction, said support member being provided with at least a first hook member, characterised in that said snap-fit connector is configured such that said first hook member can flex about a respective virtual axis extending substantially in the substantially upward direction.
  • the substantially upward direction is a relative direction, which may correspond to a use position of the fastener in which such fasteners can be used to form a substantially horizontal deck or the like, e.g. a use position of the fastener in which such fasteners can be used to attach planks or boards, positioned in a flat orientation, onto the upper surfaces of juxtaposed interspaced joists positioned such as to form a substantially horizontal grid.
  • the present disclosure provides for a fastener for attaching a board or plank to a support structure, in particular in order to form a deck or the like including multiple juxtaposed boards or planks, said fastener comprising a base portion and at least one snap-fit connector for interlockingly engaging a corresponding snap-fit element, in particular an elongate slot or recess, more in particular a dovetail groove, of the board or plank, wherein said snap-fit connector includes a support member protruding from the base portion in a substantially upward direction, said support member being provided with at least a first hook member, said fastener further comprising a pin or plug protruding from the base portion in the substantially upward direction, said pin or plug being arranged to be clamped in a section located more to the outside or lower section of the snap-fit element of the board or plank, in particular when said snap-fit element is substantially formed as a dovetail groove.
  • the pin or peg when seen in a longitudinal direction extending from the pin or peg towards the first snap-fit connector and perpendicular to the upward direction, can have, at least at one height level below the lower edge of said hook member, a width which is wider than the corresponding width of the first snap-fit connector's support member's lower portion at said height level.
  • kits of parts for attaching one or more boards or planks to a support structure, in particular in order to form a deck or the like including multiple juxtaposed boards or planks

  • the fasteners By mounting the fastener to the support element by means of a mounting mechanism substantially formed as a bayonet catch, the fasteners may be mounted to the support element in a relatively fast and relatively simple manner, which may allow relatively easy removal, in particular in comparison with prior art systems in which the fasteners had to be screwed onto a joist or the like.
  • the bayonet catchlike mounting mechanism may serve as a positioning means that can counteract that the fastener is not mounted in the right location and/or the right position, as a result of which can be counteracted that snap-fit connectors of fasteners mounted for instance to multiple substantially parallel support elements may not be sufficiently in line with each other to allow a board or plank, provided with a dovetail groove or the like, to be clipped onto said fasteners' snap-fit connectors.
  • the support face 40 may be formed by a side face or a bottom face of a support beam 4 or the like.

  • the elongate profile 30, which may be thus much longer than the partly cutaway section shown in Figure 2 , is of such design that, in case of a deck construction, its bottom surface 38 is, in the installed position, substantially spaced apart from the joist's upper surface 40, as only relatively small bottom regions 31 are abutting the joist's upper surface 40. This may allow moist coming from below, which often pulls up through wood, to escape at the upper surface 40 of the joist 4.
  • the elongate profile 30 is provided with openings 32, in particular through holes 32, allowing moisture to escape.

  • the fastener 1, especially its base portion 10 may be provided with a downward protruding element 18, which preferably can protrude in a downward direction D18, directed substantially opposite to the upward direction D1.
  • the downward protruding element 18 may have a section 181 with substantially circular or cylindrical outer face that can correspond with a substantially circular of cylindrical part 321 of an opening 32 of an attachment means 33 of an elongate profile 30 or other support element 3.
  • this may prevent that, in the installed position of the fastener 1, the fastener 1 allows play in the longitudinal direction D3 of the elongate profile 30 or other support element 3, as it is found that such play can be highly unwanted during installation of the plank 2 or board 2.
  • the downward protruding element 18 may be relatively rigid, for instance its width in the longitudinal direction D3 of the support element 3 and/or its diameter may be relatively large, e.g.
  • the downward protruding element 18 may preferably be rigidly connected to the base portion 10 of the fastener 1, for instance thus not being connected to the base portion 10 via a flexing arm or the like that allows play in the longitudinal direction D3 of the support element 3.
  • the downward protruding element 18 may be provided with one or more substantially sideward protruding or radial protruding members 19 that, in a first rotational position of the fastener 1, can slide through a corresponding recess part 322 of the opening 32 when the downward protruding element 18 is inserted into the substantially circular of cylindrical part 321 of said opening 32.
  • the one or more substantially sideward protruding or radial protruding members 19 can lock behind, below and/or within the support element 3, such as to prevent that the then rotated fastener 1 cannot be pulled back, in an upward direction, from the support element 3.
  • the fastener 1 and/or support element 3 can be arranged to limit the extent to which the fastener 1 can be rotated after its downward protruding element 18 is inserted into the opening 32.
  • the fastener 1 in particular its base portion 10, can be provided with one or more stop surfaces 100, which may cooperate with corresponding stop surfaces, for instance formed by a wall part 300, of the elongate profile 30 or other support element 3.
  • the substantially sideward protruding or radial protruding members 19 may be omitted, as for instance substantially sideward protruding, e.g.
  • base portion elements 101 which, upon rotation of the fastener 1, may engage with a corresponding locking portion 301 of the support element 3, which locking portion 301 for instance may be formed by a flange 301 of said support element 3 that can for example be formed as an elongate profile 30.
  • the fastener 1 and/or support element 3 can be arranged to push the one or more substantially sideward protruding or radial protruding members 19 against the support element 3 and/or to push the one or more base portion elements 101 against a respective locking portion 301 in the installed position of the fastener 1, for example by means of a spring.
  • the lower end of the base portion 10 can be provided with one or more wedge or chock like structures 17 with run-on surfaces 16 that can facilitate that said one or more protruding members 19 and/or said one or more base portion elements 101 can be clamped and/or pressed against a respective portion of the support element 3 in the installed position of the fastener 1.
  • bayonet like catch system is here shown in the context of a fastener 1 having a snap-fit connector configured such that its one or more hook members 13 can flex about a respective virtual axis A1 extending substantially in the substantially upward direction D1
  • the bayonet like catch system can also be advantageously utilised in another fastener 1 for attaching a board 2 or plank 2 to a support structure 5, for instance another fastener 1 comprising a base portion 10 and at least one snap-fit connector for interlockingly engaging a corresponding snap-fit recess 21 or other corresponding snap-fit element 21 of the board 2 or plank 2, e.g.
  • a relatively standard snap-fit connector having one or more hook members that flex about a virtual axis extending in the longitudinal direction D21 of the elongate snap-fit recess 21 and/or in the elongate direction D10 of the fastener 1 and/or its base portion 10.
  • the fastener 1 may be integrally formed, in particular moulded, for instance in an injection moulding process. Additionally, or alternatively, the fastener 1 may be made of a plastic material, for instance allowing its one or more snap-fit connectors 11 and/or one or more hook members 13 thereof to flex.
