Definitions

  • the present invention relates to sub-floor panels and more particularly, to free floating sub-floor panels capable of supporting a floor layer and having a rigid waterproof lower layer that permits moisture drainage and air circulation.
  • a finished floor typically consists of a sub-floor and a flooring surface, supported by the sub-floor.
  • the nature of a sub-floor will vary depending on the flooring surface it needs to support and the environment in which it must function. For example, for linoleum tile or carpet on a main floor of a house, the sub-floor may simply consist of sheets of plywood. For a ceramic tile floor a cement layer will typically also be required.
  • Basement flooring presents additional challenges; one of which its the possibility of moisture being present and another which is to insulate the floor from what could be a very cold underlying surface of poured concrete.
  • Fixed sub-floors or "non-floating" sub floors can be used in basement applications. This type of flooring may have an underlying sheet of semi rigid plastic having depending protrusions over which is placed a series of plywood panels (see e.g. WO-A-8203099 ). The panels are securely fixed-to the underlying floor using concrete bolts.
  • Fixed sub-floors may be rather labour intensive to install and rely on secure and frequent fastening to prevent movement between adjacent flooring sheets.
  • U.S. Patent No. 4,945,697 to Ott et al which teaches a floor tile and floor for direct installation on a support such as a floor or walkway without a sub-floor.
  • This patent teaches a floor system that uses floor tiles comprised of two layers, an upper layer made of ceramic material and a lower layer made from resilient material with anti-skid characteristics. The two layers are secured together to form a floor tile.
  • the lower layer includes drainage channels on the underside, that allow the passage of water underneath the floor tiles. When used outside, the tiles are spaced apart with gaps between adjacent tiles to allow vertical movement between the tiles. When the floor tiles are used indoors, the gap between adjacent tiles is filled with a flexible material that allows vertical shifting of the tiles.
  • These tiles will not provide a rigid sub-floor layer that would be capable of use in a sub-floor application for supporting a further rigid floor layer on top of the tiles since any vertical motion between adjacent tiles would cause the further floor layer to crack.
  • U. S. Patent No. 5,950,378 to Council et al Another example of a non sub-floor application is U. S. Patent No. 5,950,378 to Council et al .
  • This patent describes a composite modular floor tile for use in athletic playing surfaces such as basketball courts and tennis courts.
  • the floor tile has a top and a bottom member with support nodes extending from the bottom member which provide an air circulation space underneath the floor tiles.
  • the bottom member is made from a resilient impact absorbing material that would not provide a rigid supporting layer and therefore would not be suitable in a sub-floor application.
  • WO-A-82/03099 discloses a protective sheet for the foundation of a wall or floor.
  • This foundation wall has a large number of spaced knobs that protrude from one side and an open channel between adjacent recesses, such that there is a corresponding ridge between the knobs.
  • the system comprises subfloor panels capable of supporting a floor layer and providing under-floor drainage.
  • Each panel has an upper member and a lower member attached to the upper member.
  • the upper member is made from a sheet flooring material and the lower member is made from a waterproof sheet material.
  • the lower member has a plurality of projections extending away from the panel to support the panel above an underlying surface and to permit moisture to drain between the panels and the underlying surface.
  • the sub-floor panel 10 includes an upper member 12 of sheet flooring material and a lower member 14.
  • the lower member 14 is attached to the upper member 12.
  • the lower member 14 is of polyethylene or other suitable waterproof sheet material and includes a plurality of projections 16 which rest on an underlying surface 11 to support the sub-floor panel 10 on the underlying surface 11 and allow moisture to drain between them and to permit air circulation between the sub-floor panel 10 and the underlying surface 11 when the sub-floor panel 10 is installed.
  • Figure 1 illustrates a series of sub-floor panels 10 adjacent and interlocking one another.
  • the sub-floor panel 10 is attached to the adjacent sub-floor panel 10 using a tongue 18 and a groove 20 arrangement, which will be described later.
  • the sub-floor panel 10 may be square, and is preferably manufactured as a 4'by 4'panel, although other sizes may also be manufactured.
  • the upper member 12 is attached to the lower member 14 using an adhesive.
  • the adhesive must be compatible with the upper member 12 and the lower member 14.
  • the adhesive is Fastbond2000-NF manufactured by 3M Canada Company.
  • the upper member 12 is made from random wafer board, such as manufactured and sold under the name Waferweld by Longlac Wood Industries Inc., as opposed to oriented strand board ("OSB").
  • Random wafer board is manufactured from wood chips that have a random orientation, as opposed to oriented strand board ("OSB") in which wood strands are oriented to lay in a perpendicular fashion with the majority of strands oriented to lay with the longitudinal direction of the board.
  • the random orientation of the chips allows the random wafer board to expand evenly in all directions as opposed to longitudinal expansion tendencies characteristic of OSB which makes random wafer board less prone to buckling in this flooring application.
  • the lower member 14 may be made from System Platon manufactured by Armtec Limited.
  • the projections 16 extend away from the lower member 14 in the opposite direction to the upper member 12.
  • the projections 16 are frustoconical shaped with a bottom surface 24 and a cavity 26 extending from the bottom surface 24 towards the upper member 12.
  • the projections 16 are aligned in rows and columns to enable the panels 10 to be cut between the projections 16 without leaving any half-cut projections 16.
  • the bottom surface 24 of the projections 16 is located adjacent the underlying surface 11.
  • further levelling of the panels 10 may be required if the underlying surface 11 is uneven. This can be achieved by stacking additional layers of the lower member 14 under the lower member 14 on the panel 10 in the areas where raising is required.
  • the additional layers of the lower member 14 can be sized to fit the area that requires further leveling.
  • the panel sides may be configured in a tongue and groove arrangement.
  • the upper member 12 of each panel 10 has a tongue18 protruding from two adjacent sides and a groove 20 extending into each of the remaining sides.
  • the groove 20 is sized and operable to receive the tongue 18 to interconnect adjacent panels.
  • the tongue 18 is formed during manufacturing of the panel 10 by shaping the upper member 12.
  • a series of sub-floor panels are interlocked and located on an underlying surface 11, shown in Figure 1 , and abutting walls 15.
  • adjacent sub-floor panels are interconnected using a tongue and groove arrangement as shown in Figures 4 to 6 .
  • Each panel 10 is placed with the projections 16 adjacent the underlying surface.
  • the tongue 18 of the panel 10 is inserted into the groove 20 located on the adjacent panel 10, as indicated by arrow A shown in Figure 6 .
  • each panel 10 has a groove 28 similar to the groove 20 described above, but running along all of the edges of the panel 10.
  • a key 30 which is sized to fit within the groove 28 is utilized.
  • the groove 28 is operable to receive approximately half the width of the key 30.
  • the key 30 To install the panels 10 that use a key and groove arrangement, the key 30 must first be inserted into the second groove 28 in the direction shown by arrows B in Figure 8 . Once the key 30 is installed the panel 10 is inserted into the second groove 28 on an adjacent panel 10, in the direction shown by arrow C in Figure 8 . Similarly, adjacent panels are interconnected until the required sub-floor coverage is achieved.
  • the lower member 14 is made from any suitable waterproof sheet material.
  • the projections 16 can be located in a random pattern on the lower member 14.
  • the interlocking structure of the tongue and groove arrangement can be any interlocking combination that will prevent significant vertical shifting between adjacent panels.
  • Other adhesives may be used that are capable of securely bonding the upper member to the lower member.
