Definitions
- the present invention relates to a floor covering which is composed of a number of tiles which rest at least restrictedly displaceably on a substrate and which are mutually interconnected by connecting devices.
- Floor coverings of the type under consideration here are employed in many different practical applications, for example in patios, courtyards, or on balconies or the like where the primary purpose may be decorative or be to eliminate the cold feeling of the subjacent floor.
- Other fields of application may be industrial premises, exhibition halls and the like, where the primary purpose may be decorative or be to render the concrete floor less hard to walk or stand on.
- the present invention has for its object to design the floor covering intimated by way of introduction in such a manner that it will be dependent neither upon uniform expansion of the entire floor covering nor local expansions as a result of local heating.
- the present invention has for its object to realise a floor covering which wholly obviates the problem involved in expansion, which is simple and economical to manufacture, which eliminates the need for spacers against adjacent walls, and also compensation strips inlaid in the floor covering itself.
- the present invention has for its object to realise a floor covering which is simple to lay and which, when laid in place, displays a high level of interconnection between adjacent tiles so that these do not run the risk of being separated from one another.
- the floor covering disclosed by way of introduction is characterized in that there are provided, between adjacent tiles, gaps which are closable against spring action.
- Fig. 1 shows four tiles 1 which are included in a floor covering according to the present invention and which are placed with spacing to one another, but in those positions which they are to assume when they are interconnected.
- each tile has a surrounding edge portion 2 which is strip-shaped and which, in Fig. 1, extends in a direction towards the observer of the Drawing figure from the periphery of a tread surface 3. While the edge portion 2 has been described as strip-shaped and is shown in Fig. 1 as unbroken throughout the entire periphery of the tile 1, it falls within the scope of the present invention that the edge portion may have a number of recesses, grooves or apertures, for example to allow the passage of water.
- tread surface 3 is shown in Fig. 1 as fully covering, it is often in practice provided with a broken pattern and, on its underside (in Fig. 1 facing towards the observer) with a number of spacers, rigidifying ribs or the like which at least partly abut against the substrate 17 on which the floor covering rests when in use. This implies that the lower edges of the edge portions 2 and the lower end surfaces on the spacers etc., are flush with one another.
- the present invention may be described such that the connecting devices which are employed for interconnecting adjacent tiles are designed so as to give a certain play, such that adjacent tiles may move towards and away from one another.
- the connecting devices include a spring function which displaces adjacent tiles away from one another as far as possible within the maximum movement range defined by the connecting device.
- gaps will be formed between adjacent tiles, and these gaps are closable against the spring action in the tiles. An expansion in one tile caused by local heating of it may therefore be absorbed by the gaps which surround the heat tile.
- Fig. 2 shows the encircled area of Fig. 1 on a larger scale and from the underside of the two tiles 1.
- the edge portions 2 of both of the tiles are strip shaped and extend approximately at right angles from the tread surfaces 3 of the tiles.
- edge portions 2 on their outsides are provided, on the one hand, with recessed projections 4 with through-going recesses 5 and, on the other hand, spacers 6 whose outer ends 7 are intended to abut against the edge portion 2 of an adjacent tile 1 when the tiles are interconnected.
- the adjacent tile has a stud 8 which is produced in the edge portion 2 in that this edge portion has been provided with grooves 9 which are upwardly directed and open from its lower edge and are disposed on either side of the stud 8.
- the edge portions may have further grooves, recesses or apertures, for example to allow the passage of water.
- Figs. 5 and 6 show cross sections through interconnected tiles, partly in the region of a spacer 6 and partly in the region of a projection 4. It will be clearly apparent from these Drawing figures that, in the interconnected state of the tiles, there is a gap 10 between adjacent tiles and, in particular, between the outsides of the downwardly directed edge portions 2 of the tiles. It will also be apparent that the spacer 6 is provided only in the lower region of the edge portion 2 on the one tile, and that it abuts with its end surface 7 against the outside of the edge portion 2 on the adjacent tile.
- the stud 8 on the one tile is located interiorly in the recess 5 in the projection 4 on the adjacent tile. It will here be seen that, when the gap 10 is of full width (as is the case in Fig. 6), the inside 11 of the stud 8 abuts against the outer defining surface 12 (Fig. 2) of the recess 5. In the illustrated embodiment, the space which is formed between the outside 13 of the stud and the inner defining surface 14 of the recess 5 - and which, according to the present invention, is maintained by spring force - is equal to the width of the gap 10.
- edge portions 2 In order to hold the gap open when the tiles are not in the expanded state, use is made, as was intimated above, of spring force which is preferably at least partly realised by the edge portions 2. In order to improve such spring force and permit greater room for movement, it is appropriate that either the edge portion which carries the spacer or the edge portion against which the spacer abuts (or possibly both) be provided with weakened portions in the region of the spacer. In the illustrated embodiment, this weakening of the grooves 9 is achieved in that they are placed adjacent the spacers. An alternative solution would, however, also be to reduce the material thickness in the edge portion 2 either within that region where the spacer 6 is secured or in that region against which the spacer abuts. Naturally, it is also possible to provide grooves on both sides of the spacers 6.
- edge portions are substantially rigid and the spring force is generated by specifically provided spring means which may be disposed to interconnect movably arranged spacers with the rest of the tile or which may per se be designed as spacers.
- the spacers 6 are provided with engagement means 15 which engage with the downwardly directed edge portion 2 of an adjacent tile.
- these engagement means comprise a lower and projecting heel 15 on the end surface 7 of the spacer 6.
- the downwardly directed edge portion has a recessed area 16 where its height is reduced such that a certain space is created to the substrate 17.
- the engagement means 15 (designed as a projecting portion) will snap into the recessed area 16 of the edge portion 2 and thereby engage against its lower edge such that a vertical displacement of the tiles is prevented or at least impeded.
- the stud 8 is also provided with engagement means co-operating with the recessed projections 4 in order thereby to prevent relative vertical displacement between the tiles. It will be apparent from Fig. 4 that the stud 8 is provided in its free end with barb-like means 18 which, on insertion of the stud 8 into the recess 5, are intended to snap in behind the projection 19 interiorly in the recess 5. The projections 19 are clearly shown by broken lines in Fig. 3.
- the catch means for interconnecting adjacent tiles have been described as formed by the recessed projections 4 and the studs 8 insertible therein.
- the edge portion 2 of a tile is provided with a T-shaped projection, in which the cross or head of the T is located a distance from the outside of the downwardly directed edge portion. This distance ought to be greater than the material thickness in the downwardly directed edge portion of an adjacent tile so that the foot of the T-shaped projection may thereby be passed through a slot or a groove in the downwardly directed edge portion such that the cross or head of the T is located interiorly in the adjacent tile.
