Definitions
- the present invention relates generally to the field of artificial covering units, stones or flagstones for laying out pavements or for covering a wall surface, and is more particularly directed to such covering units giving the resulting pavement or wall surface an improved natural-looking appearance while being still easy to install.
- artificial covering units which are generally made of concrete, are well-known to lay out pavements or covering wall surfaces on residential or commercial properties, for example for defining the surface of walkways or patios.
- Such artificial covering units are advantageously relatively inexpensive to manufacture, as opposed to natural carved flagstones, but the resulting pattern is often repetitive or has what is called in this field an unnatural "linear line effect".
- Great efforts are therefore being made to design artificial stones which provide a more natural look, creating the effect of old world craftsmanship, while still retaining the ease of their manufacture.
- US patent 6,881 ,463 concerns a surface covering unit comprising primary units which are rotational tessellation of one another.
- US2006/0182923 concerns a building unit having three vertices and a pair of sides extending from each vertex, the sides of a pair being rotational images of each other.
- US application 2007/0077387 discloses a building unit resembling the one from US2006/0182923 for which two of its sides may have a midpoint bisecting the sides in two portions, each portion being a rotational image of the other portion.
- US application 2007/0098945 is a republication of US application 2006/0182923. This republished application discloses sides of the building unit which all comprise a series of straight-line segments, the segment being angled relative to at least one adjacent segment such that the general appearance of the sides is irregular.
- An object of the present invention is to provide an artificial covering unit that satisfies the above-mentioned need.
- a covering unit for use in combination with other ones of the covering units for covering a surface, the covering unit having a generally hexagonal body comprising: - a first, a second and a third pair of opposed and substantially parallel sides for defining the generally hexagonal body; wherein:
- each of the sides of each of the pairs has a central point of angular symmetry
- the second and third pairs of sides are substantially similar to each other while the first pair of sides is substantially different from the second and third pairs of sides;
- each side of the second pair is a rotational image of the sides of the third pair, whereby in use in combination with the other covering units:
- each one of the sides is matingly engageable with the sides of an equivalent pair of sides of a neighbouring covering unit;
- the covering unit has a central point of angular symmetry and is matingly engageable with a plurality of neighbouring covering unit in either a similar orientation or in an orientation of 180°.
- the sides of the first pair can be longer from the sides of the second and third pairs, and may also be provided with at least one split deviation along their length arranged so that each side of the first pair is a rotational image of the other one.
- the split deviations provided on the sides of the covering unit advantageously make it possible to obtain a pavement with a natural random look by simply using a plurality of similar artificial covering units.
- the particular shape of the covering unit which advantageously allows a lay out of the unit with the others in two opposite orientations on an individual basis improves even more the random look of the pavement while greatly facilitating the installation of the units.
- the present invention is also very advantageous for a manufacturer, since the production of the artificial covering units requires only a single shape for the mould used for moulding the covering units.
- FIG. 1 is a perspective view of a covering unit according to a first preferred embodiment of the present invention.
- FIG 2 is a perspective view of a plurality of covering units arranged together to form a pavement having a natural random look, according to a second preferred embodiment of the present invention.
- FIGs. 3A, 3B, 3C, 3D and 3E are respectively a top view, a first side view, a second side view, a third side view and a fourth side view of the covering unit of FIG.1 .
- FIG. 3F is a bottom view of the covering unit of FIG. 1.
- FIG. 4 is a top view of a plurality of covering units similar to the one illustrated in FIG.1 , arranged together to form a pavement, the covering units being arranged in two different orientations to improve the natural random look of the pavement.
- FIG. 5 is a schematic top view of an covering unit according to a further embodiment of the present invention.
- FIGs. 6A, 6B, 6C, 6D, 6E and 6F are respectively a top view, a first side view, a second side view, a third side view, a fourth side view and a bottom view of another covering unit according to the present invention.
- covering unit is intended to mean any stone, flagstone or flat slab of stone used as a paving or building material.
- present invention was primarily designed for concrete covering unit, it may also apply to other applications, such as with natural stones, hand or machine cut.
- the covering unit 10 has a generally hexagonal body 12 with a first, a second and a third pair of opposed and substantially parallel sides.
- the first pair of sides 14 comprises sides 14a and 14b
- the second pair 16 comprises sides 16a and 16b
- the third pair 18 comprises sides 18a and 18b.
- each of the sides of each of the pairs 14, 16, 18 has a central point C of angular symmetry. More particularly, the portion of the side 14a extending on the right of point C, when rotated 180 ° around point C on the left portion of side 14a, is similar to this left portion.
- Each side 14a, 14b, 16a, 16b, 18a, 18b is built according to this concept.
- the second and third pairs 16, 18 of sides are substantially similar to each other, the sides 16a, 16b, 18a, 18b all having the same length and the same shape.
- the side 18a can be seen as a translation of side 18b, while being a rotational image of each of the sides 16a and 16b.
- the first pair 14 of sides 14a, 14b is substantially different from the second and third pairs 16, 18 of sides.
- the sides of the first pair 14 preferably have a length substantially longer than a length of the sides of the second and third pairs 16, 18.
- a first pair 14 of sides shorter or of the same length than the sides of the second and third pairs 16, 18 is also within the scope of the present invention.
- the sides 16a, 16b, 18a, 18b of the second and third pairs 16, 18 are provided with at least one split deviation 20 along their length arranged so that each side 16a, 16b of the second pair 16 is a rotational image of the sides 18a, 18b of the third pair 18.
- split deviations 20 are segments dividing the corresponding sides in three portions 24, 26, 28 projecting outwardly and inwardly with respect to the body 12 of the covering unit 10.
- each of the sides 16a, 16b, 18a, 18b of the second and third pairs 16, 18 has a specific shape along its length which is formed of three end-to-end portions: a first ending portion 24, followed by the split deviation 20, which comprises a generally straight segment 26, and a second ending portion 28 similar to the first ending portion 24.
- each ending portion 24, 28 is a substantially straight segment. While conserving this general profile, the sides can however be slightly irregular, to give the covering unit 10 a more natural looking aspect. In the illustrated embodiment, the generally straight segment 26 is much longer than the ending portions 24, 28 but it should be mentioned that other arrangements are also possible.
- the sides 16a, 16b, 18a, 18b may be each provided with several split deviations, as long as each side of the second pair is a rotational image of the sides of the third pair.
- split deviation By split deviation, one could also understand a break in a segment which causes the same to deviate of a certain angle from its original line.
- a split deviation may be a segment, such as illustrated in FIG.3F, where the split deviation 20 corresponds to segment 26, and breaks the side into three portions, 24, 26 and 28, but it could also be a point breaking a line into two segments.
- each one of the sides 14a, 14b, 16a, 16b, 18a, 18b is matingly engageable with the corresponding side of an equivalent pair of sides of a neighbouring covering unit 10.
- the covering unit 10 has a central point of angular symmetry ⁇ , as best shown in FIG. 5, and is matingly engageable with a plurality of neighbouring covering units 10 in either a similar orientation or in an orientation of 180°.
- the longest side B of the covering unit 10 can be rotated around the central point of angular symmetry ⁇ to then correspond to the opposite side B'.
- the covering unit 10 is engageable with the neighbouring covering units 10 in staggered rows or in other words arranged in quincunx, that is to say an arrangement of five units with one at each corner of a rectangle and one at the center.
- the sides 14a, 14b of the first pair 14 are also provided with at least one split deviation 20 along their length arranged so that each side of the first pair 14 is a rotational image of the other side.
- the sides 16a, 16b, 18a, 18b several split deviations could be considered.
- the sides of the first pair 14 have along their length a first ending portion 24, followed by the split deviation 20, which comprises a generally straight segment 26, and a second ending portion 28 similar to the first ending portion 24.
- each of the first and second ending portions 24, 28 of the sides of the first pair 14 is a substantially straight segment.
- first ending portion 24, the split deviation 20, which comprises the generally straight segment 26, and the second ending portion 28 of the sides of the first pair 14 may be different from those of the sides of the second and third pairs 16, 18. They however bear the same reference numerals for facilitating the reference to the Figures.
- each side of a corresponding pair is adjacent to a corresponding side of each of the remaining pairs.
- each side is advantageously rotationally spaced from adjacent sides by an angle of 120°.
- each ending portion 24, 28 of each side is rotationally spaced from the adjacent ending portion 24, 26 of the adjacent side by an angle of 120°.
- other configurations could be envisaged.
- each of the sides advantageously has a chiselled upper edge 30.
- the artificial covering unit 10 is advantageously provided with a top face 32 having a texture that imitates a natural covering unit, such as a natural flagstone.
- the top face 32 has deep joints 34 dividing the top face 32 into smaller top sections 36.
- the deep joints 34 preferably extend through a portion of the height of the covering unit 10, so that when the unit is laid out, it gives the visual impression of an arrangement of smaller unit, while still retaining the advantages of handling only a larger block.
- the deep joints 34 separate the covering unit 10 into four sections 36 of various shapes and sizes.
- the covering unit 10 can be provided with any number of deep joints 34 of any shape which define any number of sections 36.
- the covering unit 10 may be breakable along the deep joints 34. This allows breaking off one or more of the unit sections 36 while still render possible a matingly engagement of the broken covering unit with other ones.
- the body 12 of the covering unit 10 is advantageously divided into a bottom part 38 devised to contact the surface to cover and an upper part
- the upper part 40 topping the bottom part 38, the upper part 40 having a contour line generally similar to the bottom part and a surface area smaller than the surface area of the bottom part whereby spaces 42 are created between the upper parts 40 of adjacent covering units 10 covering a surface.
- This preferred embodiment of the covering unit 10 improves even more the random look of the pavement, as shown in FIG. 2.
- the unit 10 may be provided with a plurality of spacers 44 distributed along the sides of the unit 10, whereby in use in combination with the other covering units 10, the spacers 44 define water drainage channels around the unit 10.
- each of the spacers 44 has a thin plate-shaped member 46 protruding from the corresponding side. More preferably, each of the spacers 44 is arranged on a corresponding vertex 48 of the hexagonal body 12. It should however be mentioned that other arrangements could also be considered.
- each covering unit 10 can be laid out in one of two orientations on an individual basis. It is worth mentioning that a plurality of different deep joint configurations may be provided. In this case, the covering units 10 are still easy to install since they still have the same generally hexagonal body 12. However, the visual appearance of the pavement is more natural. It can be easily understood from the above, that a single module is sufficient to create a multitude of different designs. There is no need to use different shapes of covering unit to obtain the sought after natural look. Also, as previously mentioned, the split deviations provided on at least four of the six sides provide an irregular profile that gives the flagstone a more natural look.
- the artificial covering unit according to the present invention can advantageously be used for creating patio, pathways, sidewalks or stepping stones for non-limitative examples.
- the covering unit of the present invention can advantageously be easily laid out to form a pavement or a wall surface where no straight lines and hardly any repetition can be seen, giving as a result, the look of old world craftsmanship.
- the installation of the units in staggered rows advantageously reduces the linear line effect compared to an installation in conventional lines.
- all of the covering unit of a pavement can be the same, but still create a visually "random" effect in which no straight lines can be seen.
- the top face 32 of the covering units 10 has several regions of the same height, thereby facilitating stacking of the covering units.
- the artificial covering unit according to the present invention has several advantages over prior art products. Indeed, its installation is very easy, does not require distinctive markers for guiding the installation, and does not require professional skills.
- the resulting pavement has no "linear effect", that is, a person walking thereon would not see any straight line in front of him or her. It has a random look, achieved with a single stone design.
- One advantage also over the flagstone described in Canadian patent No. 2,569,998 is that the covering unit according to the invention makes it easier to build an alley or sidewalk thanks to the fact that the covering unit has an angular symmetry of 180° about its central point.
- the artificial covering unit of the present invention is also very advantageous for a manufacturer, since the production of the covering units requires only a single shape for the mould used for moulding the covering units.
