DESCRIPTION OF PREFERRED EMBODIMENTS With reference to Figure 1 of the drawings, a flooring unit for use in a reticulated, temporary flooring system is designated generally by the reference numeral 10. The flooring unit comprises, broadly, a planar square-shaped floor segment 12 and connecting formation in the form of tongue formations 14 and complementary groove formations 16. The flooring unit is interlocked with one or more other flooring units having complementary connecting formations such that, in an interlocked condition of the flooring units, the connecting formations define a channel into which wires and the like may be placed. It is envisaged by the inventor that the flooring system of the invention provides for a "lay-in" type of flooring system in terms whereof wiring may be laid directly inside the open channels defined in the floor by the connecting formations post-installation without the need for the lifting of any flooring units or the hassle of having to feed any wires through conduits or underneath the floor itself.
As shown in Figure 6 of the drawings, the tongue formations 14 are fixedly embedded inside and along each of two adjacent sides of the flooring unit. Each tongue formation 18 extends perpendicularly from the side of the flooring unit. Each tongue formation further includes an elongate indentation 20; 108 which extends along an operatively upper surface of the tongue formation in parallel with the side of the flooring unit, the indentation being shaped to engage the tip of a grub screw. The complementary groove formations 16 are fixedly embedded inside and along each of the other two adjacent sides of the flooring unit. Each groove formation projects inwardly from and perpendicularly to the relevant side of the flooring unit.
The floor segment defines an opening 24 located generally above the groove formation 22 while the groove formation defines a corresponding, internally screw- threaded opening 26 aligned therewith. With reference to Figure 2A of the drawings a second embodiment of a flooring unit in accordance with the first aspect of the invention is designated generally by the reference numeral 50. In accordance with this embodiment, the floor segment includes one end thereof that is elevated in relation to an opposite end thereof. The elevated side defines the connecting formation, which may be in the form of a connecting groove formation.
The ramp flooring unit comprises a ramp-shaped floor segment 52 which defines a connecting formation 54 in the form of a groove formation 56 which projects inwardly from and perpendicularly to the elevated end of the ramp flooring unit.
The ramp flooring unit 50; 100 defines an internally screw-threaded opening 58 located generally above the groove formation. The ramp flooring unit further defines an internal connecting channel 60; 1 12 in which a connecting bar can be received to connect the ramp flooring unit to adjacent ramp flooring units.
With reference to Figure 2B of the drawings, the flooring unit, generally indicated by the numeral 100, includes a ramp-shaped floor segment 102 wherein the connecting formation 104 is defined by a tongue formation 106 which extends outwardly from and perpendicularly to the elevated end of the ramp flooring unit.
Referring to Figures 3 to 7 of the drawings a flooring system in accordance with the second aspect of the invention is designated generally by the reference numeral 200. The flooring system includes a plurality of interlocked planar flooring units 10 and, ramp flooring units 50 which define a floor surface in the interlocked condition thereof.
With reference to Figure 4 of the drawings, a tongue formation 18 of a planar flooring unit 10 is snugly received in a complementary groove formation 56 of a ramp flooring unit 50. A grub screw 204 is screwed into the opening 58 of the ramp flooring unit. The tip of the grub screw engages the indentation 20 defined on the operatively upper surface of the tongue formation of the planar flooring unit thereby securing the ramp flooring unit 50 to the planar flooring unit 10. The so interlocked planar and ramp flooring units define a channel 206 in which wires 208 may be held. Elongate covers 202 are used to close the channels and to secure the wires in the channels between the flooring units.
As shown in Figure 5 of the drawings, a tongue formation 106 of a ramp flooring unit 100 is snugly received within a groove formation 22 of a planar flooring unit. A grub screw 204 is screwed into the aligned flooring section opening 24 and groove opening 26 of the planar flooring unit. The tip of the grub screw engages the indentation 108 defined by the tongue formation of the ramp flooring unit thereby securing the planar flooring unit 10 to the ramp flooring unit 100. The so interlocked ramp flooring unit and planar flooring unit define a channel 210 in which wires 208 may be held.
With reference to Figure 6 of the drawings, a tongue formation 18 of a second planar flooring unit 10.2 is snugly received in a groove formation 22 of a first planar flooring unit 10.1 . A grub screw 204 is screwed into the aligned flooring section opening 24 and groove opening 26 of the first planar flooring unit. The tip of the grub screw engages the indentation 20 defined on the operatively upper surface of the tongue formation of the second planar flooring unit 10.2. The interlocked groove and tongue formations of the first and second planar flooring units define a channel 212 in which wires 208 are held. An elongate cover 202 is used to close the channel 212 and to secure the wires in the channel between the first and second flooring units. In this regard, it is envisaged by the inventor that not all of the channels will be adapted to receive wires and that only selected channels will be accessible for the insertion of wires. A method in accordance with a third aspect of the invention provides for a floor using the flooring system of the second aspect of the invention. The method includes the steps of laying out the planar flooring units 10, the ramp flooring units 50 defining groove formations 54 and the ramp flooring units 100 defining tongue formations 104 on a substrate surface in the desired configuration for assembly of a floor structure. Wires to be held by the channel 210 defined by the interlocking of a tongue formation 104 of a ramp flooring unit 100 and a groove formation 16 of a planar flooring unit 10 are placed between said ramp and planar flooring units. Adjacent ramp flooring units are then connected to each other by receiving the opposing ends of a connecting bar (not shown) in the complementary connecting channels 60, 1 12 of adjacent ramp flooring units.
The flooring units are interlocked with each other by receiving the tongue formations 18, 106 within the groove formations 22, 56. The flooring units are finally secured to each other by means of grub screws 204 as described hereinabove. The channels holding the wires are then closed by inserting the elongate covers 202 therein such that they are flush with the flooring units thereby defining a continuous, level floor surface.
The inventor envisages that the flooring system of the invention will allow for wires to be introduced to a temporary floor from above the substrate surface thereby alleviating the need to thread wires through conduits or lift any floor tiles or units and, further, provides for an temporary flooring solution which can be quickly assembled and which also has a high structural integrity.
