Definitions

  • the present invention relates to an adjustable foor support system, comprising a set of wooden joists and a set of adjustable floor supports attached to each joist, wherein each joist is provided with a plurality of through holes extending between first and second opposing sides of the joist, and wherein each adjustable floor supports includes a threaded screw having a foot portion adapted to rest upon a supporting surface, and a screw mount configured to engage the threaded screw, the screw mount being attached to one of the wooded joists, such that an end of the threaded screw is accessible through one of the through holes, thereby allowing adjustment of a relative position between the threaded screw and the screw mount.
  • an interior floors e.g. wooden floor or tiling
  • an underlying supporting structure e.g. a concrete structure.
  • an adjustable floor system may be provided with suitable damping between the joist and the supporting structure, thereby more efficiently dissipating mechanical energy.
  • adjustable floor system is shown in WO 97/26424 , where adjustable screws are mounted to wooden joists, such that a distance between the joist and the underlying support surface may be adjusted.
  • a floor system like this allows for localized adjustment of height so that any uneven characteristics of the underlying surface does not translate to the floor which is intended for use.
  • the system also includes limited damping, by rubber sealing elements.
  • a more effective dampening, suitable for U-section metal joists, is provided by Granab ® System 7000.
  • adjustable screws are received in screw mounts, which in turn are attached to the U-section metal joists with damping elements sandwiched therebetween.
  • the metal joist is provided with openings to allow adjustment of the screws.
  • each screw mount has two parts; a first part is fixed in a hole in the wooden joist, while a second part engages the screw.
  • a damping element is arranged between the two parts.
  • the first part resembles a piece of a U-section metal joist
  • the second part resembles the screw mount in Granab ® System 7000 mentioned above.
  • each joist on each side bridging the first and second opposing sides, is provided with at least one indentation aligned with each through hole
  • each screw mount has a main body with a threaded through hole securing the screw in an axial direction, normal to a supporting surface of the main body, and at least one pair of arms formed on opposite sides of the supporting surface and extending in the axial direction on either side of the joist, each arm in its distal end provided with a finger in snap-fit engagement with one of the indentations, so as to secure the screw mount with respect to the joist in the axial direction while allowing a limited axial play.
  • a damping element is sandwiched between the joist and the supporting surface, to allow a dampened compression of the screw mount corresponding to the axial play.
  • the screw mount comprises only one part, which is attached directly to a wooden joist which has been provided with correpsonding indentations.
  • the indentations ensure proper alignment of the floor support with respect to the joist through holes, thereby facilitating the process of moutning the floor supports to the joist.
  • the damping element may be formed as one piece with a central through hole to allow passage of the screw.
  • the damping element is formed as two pieces, arranged on opposite sides of the screw.
  • the screw mount may have two pairs of arms, i.e. two arms on eitehr side of the joist. By having two paris of arms, the attachment of the floor support to the joist becomes even more relaiable and secure.
  • the adjustable floor system 1 in figure 1 includes a screw mount 2, secured to a joist 3, and a threaded screw 4 axially engaged in a hole 5 in the screw mount 2.
  • the screw 4 is provided with a foot portion 6.
  • the foot portion 6 maybe releasably attached to the screw 4, or be integrally formed with the screw 4.
  • the foot portion 6 is intended to rest on a supporting surface 7, e.g. a concrete surface.
  • the joist 3 is provided with a through hole 8, extending between opposite sides 9a, 9b of the joist 3.
  • the screw mount 2 is arranged such that the head 4a of the screw 4 is accessible through the hole 8. This allows adjustment of the axial position of the screw 4 e.g. by means of a screw driver or an Allen key. By adjusting the axial position of the screw 4, a distance between the joist 3 and the supporting surface 7 may be adjusted.
  • the screw mount 2 has a main body 10, with a supporting surface 11 facing the joist 3.
  • the screw mount 2 further has at least one pair of arms, each pair having one arm 12 on each side of the main body 10, extending outside the joist 3.
  • each arm 12 is provided with a protruding finger 13, extending into, and engaging, an indentation 14 in the joist 3.
  • the joist 3 thus has a pair of indentations 14 for each pair of arms 12.
  • the indentations are formed on the sides 15a, 15b of the joist 3 bridging the opposite sides 9a, 9b, and aligned with respect to the through hole 8.
  • aligned means positioned symmetrically with respect to the hole 8. If there is only one pair of arms (and one pair of indentations) there will be one indentation on each side of the hole 8, positioned at the same longitudinal position along the joist as the hole 8. If there are two pairs of arms (as in the illustrated example), there will be two indentations on each side of the joist 3, positioned symmetrically along the longitudinal direction on either side of the hole 8.
  • the indentations further have such a shape that they allow a small axial play of the fingers 13, i.e. the fingers 13 are free to move a limited amount in the axial direction, resulting in relative movement between the screw mount and the joist.
  • a dampening element 16 is sandwiched between the underside 9b of the joist 3 and the supporting surface 11 of the screw mount 2.
  • the damping element is formed such that it allows passage of the screw 4.
  • the damping element 16 is formed in one piece, with a through hole for the screw 4.
  • the damping element can be formed as two pieces, arranged on opposite sides of the screw 4.
  • the joist 3 When the joist is subject to a load such that the dampening element 16 is compressed, the joist 3 is allowed to move with respect to the screw mount, thanks to the axial play of the fingers 13 in the indentations 14.
