Definitions
- the present invention relates to flooring and is particularly concerned with resilient flooring.
- This adaptation of the flooring to the characteristics of the motor system of the athlete is also advantageous in other sports, such as tennis and particularly basket ball and volley ball, which are sports in which the vertical forces exerted on the lower limbs of the players are very intense.
- springy floorings have been formed by covering a basically wooden structure with a layer of synthetic material such as polyurethane.
- a further disadvantage lies in the fact that the wooden structure means that the deformation of the flooring occurs not only in the portion acted upon directly by the weight of a person standing on it but also in adjacent parts. Thus, vibrations may be propagated through the flooring , and this is particularly harmful for example, when two athletes are running very close together on a track having a springy flooring.
- the object of the present invention is to provide flooring of the type specified above which does not have the disadvantages described.
- the present invention provides resilient flooring characterised in that it comprises a layer of material which resists compression and is provided underneath with resiliently compressible support formations at least partially separate from each other.
- a flooring is formed which retains its springy behaviour even when rather high loads are applied, without the flooring itself exhibiting any stiffening phenomena.
- the springiness of the flooring indeed corresponds to the resilience of the support formations which, being at least partially separate from each other, retain a resilient behaviour even when subject to considerablecompression.
- the support formations may be distributed uniformly over the lower surface of the flooring, for example in a grid-like arrangement, so as.to give the flooring absolutely homogenous deformation charactersitics, avoiding the formation of more or less yielding zones.
- the layer of rigid material has a high shear stress compliance such as to prevent substantial transmission of deformation waves across the surface of the flooring in use. T hus,another of the disadvantages typical of conventional springy flooring is remedied.
- the flooring according to the invention is formed integrally from moulded, vulcanised rubber, with additions of sulphur and mineral fillers in the portions defining the rigid layer so as to give this layer the necessary charactersitics of resistance to compression and wear.
- this makes it easy to form the flooring in panels or tiles which can be placed on a base that is finished only very roughly, and can be connected together by jointing and/or gluing.
- the support formations of the flooring are constituted by pegs projecting from the lower surface of the layer of rigid material.
- the final characteristics of the resilience of the flooring may thus be adapted to the specific requirements of use both by.modifying the dimensions of the pegs and by varying the density of their distribution over the lower surface of the rigid layer of flooring,or even by modifying the characteristics of hardness and resilience of the material constituting the pegs themselves.
- the fact that the flooring is , so to speak, suspended on the pegs means that any moisture or water collected ) on the base may flow.through the space between the plane of the flooring and the base.
- the layer of rigid material, and a further tread layer (of polyurethane, linoleum, PVC, etc.)possibly superimposed thereon may have holes for allowing rain or water to flow into the interspace so as to prevent the formation of puddles of water on the surface of the flooring.
- the flooring according to the invention is thus particularly suitable for open-air use in hot countries.
- the flooring also has a considerable sound-proofing effect which makes its use advantageous in environments other than those intended for sporting activities, such as, for example, places adapted for use as offices, laboratories or workshops for carrying out light engineering work.
- a modular element of flooring according to the invention is generally indicated 1 and is in the form of a rectangular tile.
- FIG 2 the edges of two tile elements 1 are shown in their laid position on a base B constituted, for example, by a subsurface of asphalt or cement,or an existing floor.
- Axially compressible cylindrical pegs 3 constitute resilient support formations for the flooring.
- the pegs 3 are integral with the layer of rigid material 2.
- each element 1 of the flooring is moulded and vulcanised from a single mass of rubber or elastomer, for example, rubber having a hardness of between 35 and 45 Shore-A.
- the portion of the rubber mass constituting the surface from which the pegs 3 project has high quantities of sulpur and fillers added to it, so that this portion hardens until it reaches a hardness value which is typically between 90 and 100 Shore A.
- Each element 1 may be manufactured individually.
- the flooring according to the invention may be formed as a continuous sheet, which is subsequently cut and divided into modular elements constituted by - panels or tiles.
- the modular elements are normally provided with coupling surfaces which are a mating fit.
- the layer of rigid material 2 has projections 4 on two adjacent sides, which are made by milling.
- the rigid layer 2 has a groove 5 - also made by milling.
- Each element 1 may thus be connected by a mating fit with other similar elements in the sequence of laying the flooring schematically illustrated in Figure 3.
- the modular elements 1 may be used both for free laying and for fixed laying. In the latter case, the connection between the adjacent modular elements is strengthened by gluing.
- the flooring according to the invention has resilient characteristics which make it advantageous for use in sporting establishments, particularly on running tracks, tennis courts and courts for basket ball and volley ball, since it improves the speed of the athletes and, in particular, considerably reduces the forces and harmful fatigue of their muscles and tendons.
- the characteristics of resistance to compression of the layer 2 and the pegs.3 are selected so that the resilient characteristics of the flooring correspond essentially to the resilient characteristics of axial - compression of the pegs 3.
- the flooring keeps its resilient behaviour even when high loads are applied, thus avoiding the stiffening characteristic of conventional flooring in response to violent forces.
- the curve reproduced in Figure 4 was obtained with rubber flooring of the type illustrated in Figure 2, comprising a rigid layer 2 with a hardness of about 90 Shore A and having underneath a rectangular grid-like array of support pegs 3 constituted by rubber with a hardness of 35 Shore A.
- the pegs which have a height and diameter of about 7 mm, are arranged in rows located at a distance (measured from the axes of the pegs 3) of about 3 cms. The distance between the axes of two adjacent pegs in each row is about 2 cms.
- the overall resistance to compression of the pegs 3 corresponds approximately to the resistance to compression which would initially be given by a layer of rubber having a hardness of about 3.5 - 4 Shore A.
- the overall resistance to compression of the pegs 3 is thus at least an order of magnitude less than the resistance to compression of the layer 2.
- the functional relationship between the deformation of the flooring and the force applied is approximately linear over a'wide range of values of the applied force, without the flooring exhibiting any stiffening phenomena.
- the resilient characteristic of the flooring may thus be varied widely so as to adapt to specific requirements in use, both by the selection of the material used for forming the pegs 3 and by the variation of the dimensions of the pegs themselves or even by varying the density of distribution of the pegs on the lower surface of the rigid layer 2 of the flooring. This density may be varied within wide limits, while maintaining the homogeneity of the distribution which gives the flooring resilient characteristics that are distributed uniformly over its surface without the formation of' more or less yielding zones.
- the material forming the layer 2 is selected so as to give a high resistance to compressive forces.
- the flooring according to the invention thus remedies a typical disadvantage of springy flooring with a wooden structure, in which deformation waves are propagated through the surface of the flooring itself.
- the upper surface of the rigid layer 2 normally has strength and finishing characteristics such as to allow its direct exposure to treading. In most sporting applications, it is,however, preferable to provide the flooring with an upper tread or surface layer 6 constituted, for example, by a layer of rubber or plastics material, or wood.
- This tread layer may be in sections 6 which reproduce the layout of the elements 1 ( Figure 2) or in the form of sheets 7 which are placed on the flooring already laid ( Figure 3).
- each section of the tread layer 6 is glued or heat-sealed to the underlying layer 2 so as to be an integral part of the flooring element 1.
- the sheets 7 may simply be placed carefully on the underlying flooring so as to allow the sheets 7 themselves to be removed and the flooring to be dismantled.
- the sheets 7 may be glued to the upper surface of the layer 2 of elements 1. In this assembled arrangement, the sheets 7 render the connections between the elements .1 of the flooring more secure
- the upper surface of the rigid layer 2 is highly planar so as to facilitate the laying of the battens. themselves.
- the flooring according to the invention is, so to speak, suspended on the pegs 3 means that the flooring itself may be located on bases which are only roughly finished, the irregularities being absorbed.
- holes 8 may be formed in the rigid layer 2 and the tread layer 6 placed thereon, which put the upper surface of the flooring into communication with the spaces between the pegs 3.
- the holes 8 thus allow any water(for example, rain) which collects on the upper surface of the flooring to flow into the space beneath the plane of the flooring itself.
- FIG. 5 illustrates another embodiment of the flooring according to the invention, in which each element 1 includes a grid-like support structure 13 of resiliently compressible material (for example, soft rubber).
- resiliently compressible material for example, soft rubber
- the sides of the meshes of the grid structure 13 constitute support formations at least partially separate from each other and having a resilient behaviour about the same as the resilient behaviour - of the pegs 3.
- the resilient characteristics of the flooring may be modified by using materials of a different hardness for the manufacture of the support structure 13 or by modifying the dimensions and the form of the meshes of the structure 13 itself.
- the structure 13 may be formed by cutting from the layer of rigid material 2.
- both the layer 2 and the support structure 13 are formed from a single mass of rubber by a process substantially similar to that described with reference to the elements 1 illustrated in Figures 1 to 3.
- the rigid layer 2 and the support structure 13 may be manufactured separately and subsequently glued together.
- a further alternative is to form the grid support structure 13 in the form of strips intended to be made up on the base B so as to form a resiliently compressible support plane for the layer of rigid material 2 defining the plane of the flooring.
