Definitions

  • the present invention relates to floor mats, more particularly to dust control mats which are placed on existing floor coverings in shops, offices and other premises to absorb dust, dirt and moisture from the shoes of people walking over them and which are then regularly removed for cleaning and maintenance and replaced or substituted by other mats of the same type.
  • Such mats are conventionally composed of a rubber or plastics backing with a pile fabric extending over at least the central part of the upper surface.
  • a floor mat combination comprising one or more detents detachably securable to a floor surface and a mat having a back surface of flexible but substantially incompressible sheet material formed with one or more recesses whose side walls constitute substantially rigid abutments located within the perimeter of the mat and extending generally perpendicular to the mat, the abutment(s) on the mat being arranged so that when the mat overlies the detent(s) the abutment(s) on the mat abut against or are in close proximity to complementary abutment(s) on the detent and thereby restrict or prevent lateral movement and/or rotation of the mat relative to the detent.
  • the detent can be a platen of wood, metal, plastics, rubber or other relatively rigid material fixed to the floor covering by adhesives, tape, screws, nails, pins or in any other convenient way or fixed to the underlying floor either directly or through the floor covering.
  • the mat is rectangular and formed with a rectangular recess in its back surface and the detent is a rectangular platen or pad slightly smaller in area than the recess but of similar shape.
  • a non-creep floor mat system for a tiled floor comprising a floor mat having in its back surface a recess bounded by a substantially rigid essentially perpendicular wall, and a detent designed to underlie the floor mat on a floor surface and having a shape and size similar to but slightly less extensive than the shape and size of the recess in the back surface of the mat, characterised in that the detent is a tile designed to form part of the tiled floor but having a thickness significantly greater than the thickness of nearby tiles on the tiled floor, whereby the extra thickness of the tile detent enables it to fit into and interact with the recess in the floor mat back surface to restrict or prevent creep of the floor mat over the tiled floor.
  • the tiled floor will normally be a carpet-tiled floor, that is to say a floor covered with carpet tiles composed of a backing and a fibrous or pile upper surface.
  • the tiles may be loosely laid on the underlying floor surface or may be attached to it, e.g. with adhesive, in any convenient or conventional manner.
  • the tiles may be of any shape which will tile a floor and need not all have the same size or shape although for convenience they are all of the same surface area and shape and are suitably square.
  • the extra thickness of the anchoring tile acting as detent as compared with neighbouring carpet tiles must be sufficient to permit significant interaction between the exposed parts of the edges of the tile and the wall of the recess in the floor mat and is preferably at least 0.3 cm. However, it should not be significantly more than the thickness of the floor mat, otherwise it will cause unevenness in the floor mat upper surface and may trip an unwary walker. For use with conventional dust control mats its thickness will usually be not more than 0.6 cm.
  • the upper surface of the anchoring tile is preferably free from the fibrous or pile material which covers the upper surface of the ordinary carpet tiles in order to make it more readily identifiable and it may be made smooth, even ultra smooth to take advantage of the principle of "stiction" mentioned in our GB Patent 2,195,531. In such a situation the extra thickness of the anchoring tile and the depth of the recess may be reduced or possibly even eliminated because of the good friction between the tile and the back surface of the mat.
  • the anchoring tile may be made of similar essentially incompressible material to the backing used on ordinary carpet tiles, for example bitumen or polyvinyl chloride. If desired, the anchoring tile could be manufactured so that not all of it is of greater thickness, the region of greater thickness forming a projection from the upper surface of the remainder of the tile, but such a construction would be more difficult to produce and would not lead to further advantages.
  • the tiled floor may be provided with more than one anchoring tile of extra thickness. These may be relatively close to or even touching one another so that they are overlain by the same floor mat, which is then provided with a plurality of recesses to accommodate their extra thickness, or they may be more widely separated so that they interact with different floor mats.
  • the anchoring tiles may be moved from point to point around the floor as required or desired.
  • the floor mat may be a dust control mat or other mat and its backing may be made of rubber or plastics material or other convenient, usually washable material.
  • the backing of the mat may be flexible but is intended to be substantially incompressible so that the side wall of the recess or recesses formed in it is substantially rigid. This ensures that, when the side wall of the mat recess moves into abutting contact with an exposed edge of the anchoring tile, essentially no further deformation of either occurs, such as would lead to further movement of the mat in the same direction relative to the underlying tile. Synthetic rubbers and plastics such as nitrile rubber are conveniently used for the backing of the mat.
  • the depth of the recess in the mat should be correlated with the extra thickness of the underlying anchoring tile so that there is sufficient contact to prevent movement. Too little contact can lead to overriding.
  • the depth of the recess is 0.3 to 0.6 cm. If the mat has a normal backing thickness greater than the desired recess depth the recess can simply be an area thinner than the remainder of the backing. Usually, however, the backing is made thicker around the perimeter of the recess and tapers towards the periphery of the mat, being often as thin at the periphery of the mat as in the recess itself or even thinner.
  • the shape of the recess should be similar to the shape of the underlying anchoring tile, i.e. it should preferably be square when the tiles are square, but its area should be slightly greater to enable the anchoring tile to fit into it.
  • the extra area can be very small, 3 % or less, when it is desired to prevent essentially any movement, or can be somewhat larger, up to 15 % or more, when some movement is permissible.
  • the invention also includes a process for providing a carpet-tiled floor which comprises laying carpet tiles on a floor surface and is characterised in that one or more anchoring tiles which have a greater thickness than surrounding carpet tiles are included in the layout and in that a floor mat having a recess in its back surface of a shape and size similar to but slightly larger than the shape and size of the anchoring tile(s) is laid on top of the carpet-tiled floor so that its recess fits over the anchoring tile (or one of the anchoring tiles), whereby creep of the mat relative to the carpet-tiled floor is restricted or prevented.
  • the invention also includes a set of carpet tiles for laying a carpet-tiled floor, the set also including at least one anchoring tile of significantly greater thickness than the other tiles and preferably free from fabric or pile material on its upper surface.
  • a floor surface 10 is provided with a floor covering of square carpet tiles 11 of size 50 ⁇ 50 cm, one of which 11A is about 0.3 cm thicker than the others (1.2 cm as compared with 0.9 cm) and lacks the fibrous or pile material on its upper surface which is present on the other tiles.
  • a dust control mat 12 of size 80 ⁇ 120 cm and overall thickness about 1 cm having a pile fabric on its upper surface apart from a narrow border and a backing 13 of nitrile rubber is provided with a square recess 14 of size 51 ⁇ 51 cm and depth 0.3 cm.
  • the backing Around the perimeter of the recess the backing has a thickness of 0.47 cm and it tapers to a thickness of 0.17 cm at the periphery of the mat. This is placed over the anchoring tile 11A and surrounding tiles so that its recess 14 fits over the tile 11A. Movement of the mat more than 1 cm in any direction as a result of creep is prevented by the essentially incompressible side walls of the recess 14 abutting against the essentially incompressible exposed edges of the mat 11A.
