Description

Tile and Tile Holding Device The present invention relates to a tile and a tile holding device and particularly, but not exclusively, to a tile and tile holding device for a roof.

When laying tiles or slates upon a roof it is known to first secure a number of lengths of wood or batten upon the roof joists, with the battens being arranged substantially parallel to each other and substantially transverse to the roof joists. The tiles and/or slates are then placed upon the roof such that they bridge two adjacent lengths of batten.

Slates are typically nailed to each batten they traverse, while tiles, which may comprise a pedestal arranged on the underside of the rear of the tile, can be placed upon the batten with the pedestal arranged uppermost of the roof and beyond the uppermost batten. Accordingly, the pedestal acts to prevent the tile from sliding over the batten and down the roof. The rear of the tile then becomes held down by the front of a tile arranged further up the roof, while the front of the tile may be nailed to the lower batten.

In both cases however, it can be difficult to remove the tiles or slates without damaging the tile or slate and by passing a nail through the slate or tile to secure the slate or tile to the roof, it is possible that the slate or tile could break.

In addition when laying tiles to a wall, for example, it is common to use an adhesive.

This often leads to excessive waste and requires that any excess adhesive is cleaned from the tile before the adhesive sets. The setting time itself also poses a problem as tiles placed upon the wall often move slightly under gravity, which can lead to a misalignment of the wall tiles. Moreover, once the adhesive has set, the tile cannot be removed and subsequently reused.

I have now devised a tile and tile holding device which alleviate the above mentioned problems.

In accordance with the present invention as seen from a first aspect there is provided a tile, the tile comprising a substantially planar body and a tile projection which extends from an underside thereof, the projection being arranged to detachably engage with a tile holding device to secure the tile to an area being tiled.

The at least one tile projection enables the tile of the present invention to be quickly and replaceably secured to a desired area without the requirement for nailing or the use of an adhesive.

The tile preferably further comprises a flange which extends along an edge of the tile and which preferably extends out of the plane of the body of the tile. Preferably, the tile comprises a rear flange extending along a rear edge of the tile, which is arranged to engage under a further lip of the tile holding device, and a front flange which extends along a front edge of the tile.

The front flange preferably extends downwardly from the front edge of the tile and the rear flange preferably extends upwardly from the rear edge of the tile.

The tile preferably further comprises a plurality of ridges disposed on an upper surface thereof, which extend along the length of the tile and which are arranged at one side of the tile. Preferably, the tile further comprises a plurality of depressions disposed on an underside thereof, which extend along the length of the tile substantially opposite the one side. The depressions formed on one tile preferably cooperate with the ridges disposed at the one side on the upper surface of an adjacent tile to minimise any relative lateral movement.

Preferably, the ridges and depressions are of complementary shape and preferably further provide a labyrinth seal to minimise any water penetration between adjacent tiles.

In a further embodiment, the front flange preferably curves downwardly and then upwardly so as to define a channel or gutter region. When this tile is placed at the eve of a roof for example, the gutters disposed on adjacent tiles cooperate to form a continuous gutter that extends across the full width of the roof to collect rainwater that runs off the roof.

In yet a further embodiment, a side edge of the tile preferably comprises an end face which extends downwardly from the body of the tile and then upwardly, to create a substantially V-shape channel to form a valley in a roof.

The tile preferably further comprises a passageway which extends substantially within the planar body which is arranged to receive a fluid, such as water. The passageway preferably comprises an inlet and an outlet, which preferably extend through a side edge of the tile and in particular, the rear edge. The tile is preferably formed of a heat conductive material so that heat can transfer between the fluid within the passageway and the body of the tile to enable the fluid to become heated by the tile and/or the tile to become heated by the fluid.

Accordingly, in one embodiment, the tile and passageway may be used as water heating system for generating hot water. In this embodiment, the tile is preferably of a 1 5 dark colour such as grey or black, to maximise the absorption of heat from the sun, for example. In this case, it is envisaged that the tile may be applied to a roof or an external wall of a building, for example. In a further embodiment, the tile and passageway may be used as a heater, with heated water being used to warm the tile.

In this case, it is envisaged that the tile may be applied to an internal wall or floor.

The passageway preferably further comprises a heater element to prevent to minimise any frost development within the passageway.

The passageway is preferably disposed upon a body section that is removably coupled to the body of the tile using fixing means. Preferably, the body section is received in a body recess disposed at the underside of the tile.

The projection preferably extends from the body section and comprises an elongate barb which preferably extends along the body section.

Preferably, the tile further comprises a recess disposed at an upper surface of the tile, substantially adjacent the body recess, for receiving a solar panel and/or a Peltier device. Accordingly, the tile may be further used to generate electricity. In the case of the solar panel, the electricity would be generated by exposing the panel to sunlight, for example, whereas, the Peltier device would be configured to generate electricity in dependence on a temperature gradient existing across the device.

By positioning the solar panel and/or Peltier device substantially adjacent the passageway, then the fluid within the passageway is found to limit the working temperature of the solar panel and Peltier device to within a suitable temperature range. Moreover, the fluid within the passageway is found to enhance a temperature gradient between an outwardly facing surface and an inwardly facing surface, with respect to the tile, of the Peltier device, and thus improve the generation of electricity therefrom.

The solar panel and/or Peltier device are preferably secured within the recess at the upper surface of the tile using the fixing means. Preferably, the fixing means provides an electrical connection for the solar panel and/or Peltier device to the underside of the 1 5 tile and an electrical connection to further tiles and/or electrical devices. Preferably, the fixing means comprises a screw and/or a nut and bolt type fastener.

Preferably, recess disposed at the upper surface of the tile comprises a cover which is arranged to seal the solar panel and/or Peltier device within the recess. The cover is preferably transparent to enable sunlight to pass onto the solar panel and/or Peltier device.

Embodiments of the present invention will now be described by way of example only with reference to the accompanying drawings, in which: Figure 1 is a perspective view of a tile and body section according to a first embodiment of the present invention, from above; Figure 2 is perspective view of the tile and body section of figure 1, from below; Figure 3a is a plan view of the tile of figure 1; Figure 3b is a sectional view of the tile of figure 3a, taken across line A-A Figure 4 is a perspective view of a tile according to a second embodiment of the present invention; Figure 5 is a perspective view of a tile according to a third embodiment of the present invention; Figure 6a is a perspective view of the tile holding device according to an embodiment of the present invention; Figure 6b is a sectional view of the tile holding device of figure 6a, taken across line B-B; Figure 7 is a perspective view of a water heating and electricity generating system according to an embodiment of the present invention; and, Figure 8 is a sectional view of the system of figure 7, taken across line C-C.

Referring to figures 1 to 3 of the drawings there is illustrated a tile lOOa according to a first embodiment of the present invention. The tile lOOa may be formed of stone or slate for example and comprises a substantially planar rectangular body 101. The front edge of the tile lOOa is turned downwardly to form a downwardly extending flange 102, while the rear edge of the tile is turned upwardly to form an upwardly extending flange 103.

At one side of the tile lOOa on the upper side thereof, there is provided a region 104 which is depressed into the upper surface 101. The depressed region 104 comprises a series of ridges 105 which extend longitudinally of the tile lOOa, between the front and rear flange 102, 103. The ridges 105 are illustrated as being of a square cross-section, however, it is to be appreciated that ridges 105 having other cross-sectional shapes could also be used.

At the opposite side of the tile on the underside thereof, there is provided a region 106 which is depressed into the underside of the tile lOOa. The region 106 comprises a plurality of depressions 107 (only one of which is illustrated in figure 2) formed within the depressed region 106, which extend longitudinally of the tile lOOa on the underside thereof, from the front flange 102 to the rear flange 103, and which extend below the surface of the underside tile lOOa. When two tiles lOOa are placed together in a side-by-side arrangement, the depressions 107 formed in the depressed region 106 on the underside of the one tile lOOa locate with the ridges 105 formed in the depressed region 104 on the upper surface of the other tile lOOa. The ridges 105 and depressions 107 are of a complimentary shape so that when the tiles lOOa are placed together, the interlocking nature of the ridges 105 and depressions 107 minimise any lateral movement of the tiles with respect to each other. In addition, the ridges 105 and depressions 107 provide a labyrinth seal which minimises the ingress of rainwater, for example, between the adjoining tiles. The combined thickness of the tile lOOa in the depressed region 104 at the one side of the tile and the depressed region 106 at the opposite side of the tile substantially corresponds to the thickness of the tile lOOa at the centre thereof. Accordingly, when adjacent tiles are placed together, the upper surface of each tile lOOa extends in substantially the same plane.

The tile lOOa further comprises a body recess 108 formed on the underside thereof, within the body 101 of the tile 100. The recess 108 is arranged to receive a body section 109 which comprises a convoluted channel 110 formed therein. The channel extends through an upper surface of the body section 109 and comprises an inlet 111 and an outlet 112 for separately allowing water or similar to enter and leave the channel 110, respectively. The inlet 111 and outlet 112 are arranged to separately align with an inlet 113 and an outlet aperture 114 formed in the tile lOOa, which extend out through a rear edge of the tile 100.

The body section 109 further comprises a plurality of cavities 115 which extend partially within the body section 109 and are arranged to locate with protuberances 116, which extend from the underside of the tile body 101 within the body recess 108.

The protuberances 116 comprise an aperture 117 formed substantially at a central position thereof, which extend from an upper side of the tile body 101 to the underside of the body recess 108. Similarly, each cavity 115 comprises an aperture 118 formed therein, substantially at a centre thereof, which are of a reduced diameter compared 1 0 with the respective cavity 115.

The body section 109 is secured within the body recess 108 by a plurality of nut and bolt type fasteners 119 which are arranged to extend within the apertures 118 formed within the cavities 115 and the protuberances 116 and which thus extend from an upper side of the tile lOOa to the underside thereof. Once the body section 109 is secured within the body recess 108, the upper region of the channel 110 becomes closed by the underside of the body recess 108 and the inlet 111 and outlet 112 of the channel 110 becomes aligned with the inlet 113 and outlet aperture 114 at the rear of the tile lOOa.

The body section 109 further comprises a projection 120 disposed along the edge thereof, which is arranged substantially adjacent the front flange 102 of the tile lOOa.

The projection 120 extends substantially parallel to the front flange 102 and comprises a forward facing barb 121. It is to be appreciated however, that the projection 120 may be disposed upon the body 101 of the tile lOOa.

The tile lOOa further comprises a recess 122 formed at an upper region of the tile lOOa, substantially opposite the body recess 108. The recess 122 is arranged to receive a solar panel 123 and/or a Peltier device 124, which is/are secured within the recess 122 by the nut and bolt type fasteners 119 which further provide an electrical connection of the solar panel 123 and/or the Peltier device 124 to the underside of the tile lOOa. If required a transparent cover (not shown) may be provided over the solar panel 123 and/or Peltier device 124 to seal the recess 122.

Referring to figure 4 of the drawings, there is illustrated a tile lOOb according to a second embodiment of the present invention. In this embodiment, the front flange 102 of the tile lOOa of the first embodiment is formed into a substantially U-shaped gutter that extends from the front edge of the tile bOb. The depressed region 104 on the upper surface at one side of the tile 100 extends into the gutter 125. Similarly, the depressed region 106 formed on the underside at the opposite side of the tile lOOb extends around the underside of the gutter 125. The ridges 105 and depressions 107 formed within the depressed regions 104, 106, respectively, extend around the gutter at the respective sides thereof such that when adjacent tiles lOOb are placed together the ridges 105 and depressions 107 cooperate to minimise any relative lateral movement.

The tile lOOb illustrated in figure 4 is arranged for fitting along the eves (not shown) of a roof (not shown) such that the gutter 125 of adjacent tiles lOOb partially overlay one 1 5 another at the side edges thereof to form a continuous gutter along the eve (not shown) of a roof (not shown). Each tile gutter 125 is arranged at a slight decline to the surface 101 of the tile bOb, such that the resulting continuous gutter that extends along the eve (not shown) of a roof (not shown) can collect water which runs off the roof (not shown) and subsequently directs the water to one side thereof for transfer to a down pipe (not shown) or similar.

Referring to figure 5 of the drawings, there is illustrated a tile 1 OOc according to a third embodiment of the present invention. In this embodiment, one of the side edges of the tile lOOa of the first embodiment is replaced with a substantially V-shaped channel 126 that extends at an angle to the opposite side edge of the tile lOOc. The V-shaped channel 126 is suited for creating valleys in a roof (not shown) where, for example, two roofs (not shown) meet at an angle. The valley tile lOOc illustrated in figure 5 exhibits a V-shaped channel 126 wherein the V-shaped channel 126 comprises a first face 126a which extends down from the upper surface 101 of the tile lOOc and a second face 126b which extends upwardly from the distal end of the first face 126a; a neighbouring valley tile (not shown) which adjoins the valley tile 1 OOc illustrated in figure 5 comprises a V-shaped channel 126 at the opposite side of the tile compared to the tile illustrated in figure 5, such that the channels 126 become inserted into each other when placed upon the roof (not shown). Alternatively, one of the tiles lOOc of the pair forming the valley may only comprise a downwardly extending face 126a which extends within the V-shaped channel 126 disposed on the neighbouring tile lOOc.

Referring to figure 6 of the drawings, there is illustrated a tile holding device 200 according to an embodiment of the present invention. The tile holding device 200 may be formed of plastic material and comprises a substantially planar elongate base 201 that is substantially rectangular in shape when viewed from above. A wall 202 is disposed upon the base 201 and extends substantially along the length of the base 201. The wall 202 extends from the base 201 and is resiliently biased in a plane that extends substantially perpendicularly to the plane of the base 201. The wall 202 may be formed integrally with the base 201 and comprises first and second lips 203, 204 which separately extend to either side of the wall 202 from an upper region thereof.

The lips 203, 204 extend substantially over the base 201, along the length of the wall 202 and curve from the wall 202 toward the base 201.

The base 201 comprises a plurality of apertures (not shown) which extend along the length of the device 200 such that screws or nails (not shown) for example, can be passed through the apertures (not shown) to secure the holding device 200 to the area to be tiled. The wall 202 similarly comprises a plurality of apertures 205 disposed along the length thereof which are arranged to align with the apertures 113, 114 formed at the rear of the tile 1 OOa, 1 OOb, 1 OOc.

Referring to figures 7 and 8 of the drawings, there is illustrated a system 300 for heating water. The tiles, for example the tiles 1 OOa of the first embodiment, are secured upon a roof (not shown, or an external wall) of a building (not shown) using the tile holding device 200 described above. The tile holding devices 200 are secured across roof joists (not shown) in a substantially parallel configuration and spaced apart a distance substantially corresponding to the length of the tile lOOa. In order to secure the tiles lOOa in place, the rear flange 103 of each tile lOOa is secured under a first lip 203 on one tile holding device 200 and the tile lOOa then lowered so that the barb 121 on the projection 120 snap engages under the second lip 204 of an adjacent holding device arranged lower down the roof (not shown).

Once all of the tiles lOOa have been secured in place over the roof (not shown), the inlet 113 to the channel 110 of each tile lOOa is coupled to a common "flow" duct 301 via a coupling connection 302 which is arranged to pass through an aperture 205 formed within the wall 202 of the holding device 200 into the inlet 113. The outlet 114 from the channel 110 of each tile 1 OOa is coupled to a common "return" duct 303 using similar coupling connections 302, which also extend through an aperture 205 formed within the wall 202 of the holding device 200 into the outlet 114, thereby providing the typical "flow and return" system. A pump (not shown) is then switched on to pump water for example, from the flow duct 301, around the channel 110 within each tile lOOa and then back to the return duct 303. The exposure of the tile 102 to the sun (not shown), by positioning the tile lOOa upon a roof (not shown) or external wall (not shown), coupled with the heat conductive nature of the tile 1 OOa is found to cause the water within the channels 110 to become heated. This heated water may then be transferred to hot water outlets (not shown) within the building (not shown) or a heating system (not shown). In the latter case, it is envisaged that the heated water could be transferred to a similar arrangement of tiles lOOa embedded within a floor (not shown) of a building (not shown) or upon an internal wall (not shown) of the building (not shown), for example. The heated water can then give up the heat associated therewith to the tiles lOOa embedded within the floor (not shown) and/or positioned upon the internal wall (not shown) to heat the building (not shown). Alternatively, it is envisaged that a similar arrangement of tiles lOOa arranged within a building (not shown) may take heated water direct from a conventional boiler (not shown).

The tiles lOOa of the system disclosed in figures 7 and 8 further comprise a solar panel 123 and a Peltier device 124 secured thereon. The electrical connections, namely the nut and bolt type fasteners 119 to the solar panel 123 and the Peltier device 124, disposed at the underside of the tile lOOa are then connected, such that the electrical connections 119 having a first polarity are connected to a common first power rail (not shown) and the electrical connections 119 having a second polarity are connected to a common second power rail (not shown).

On exposure to sunlight, the solar panel 123 will generate electricity which can be extracted from the first and second power rails (not shown) to power electrical devices (not shown). Similarly, the side of the Peltier device 124 which faces the sun (not shown) will become heated with respect to the underside thereof and therefore, a temperature gradient will become established between the upper and lower surfaces of the device 124 which can be used to generate electricity. The close proximity of the channel 110 of each tile 1 OOa to the respective solar panel 123 and the Peltier device 124 enables the water within the channel 110 to effectively cool the panel 123 and the device 124 and thus maintain the panel 123 and device 124 to within a suitable temperature range. In addition, the cooling of the underside of the Peltier device 124 is found to further enhance the temperature gradient for an improved electrical generation therefrom.

From the foregoing therefore, it is evident that the tile and tile holding device of the present invention provide for a simple yet effective means of coupling tiles to an area, 1 0 such as a roof, a wall or a floor. The tile further facilitates an environmentally friendly generation of electricity and heating of water.
