[0001] The invention relates to a parallelopiped paving stone wherein the ratio between
the length and the width of said paving stone is at least substantially an integer.
[0002] Such paving stones have been produced for many decades already and can be laid in
several types of bond. Thus e.g. a stretching bond is known, wherein the stones are
laid in rows, being in line, and wherein the stones in the one row are staggered along
half the length of a stone with respect to the stones in the other row. Besides that
the twilled bond is known, in which the stones are laid perpendicularly to each other,
usually at an angle of 45 degrees to the longitudinal axis of the road.
[0003] A further type of bond that is often used is the so-called English bond, wherein
in a first block a few stones are disposed beside each other in the same direction,
and in an adjacent block the same number of stones is disposed in a direction perpendicularly
to the stones of the first block.
[0004] With the known paving stones it is thus possible to provide variations in the laying
pattern.
[0005] The object of the invention is to increase the number of possible variations in the
laying pattern while making use of such a paving stone.
[0006] According to the invention this can be achieved in that the ratio between the length
and the thickness is likewise at least substantially an integer, which is not the
same as the integer indicating the ratio between the length and the width.
[0007] By using such a paving stone the number of possibilities for laying stones can be
doubled, since the various bonds can be realised in a first position of the stones
and in a second position of the stones, the stones in said second position being turned
about their longitudinal axis through an angle of 90 degrees with respect to said
first position.
[0008] The invention will be explained in more detail hereafter with reference to a few
possible embodiments of a stone according to the invention diagrammatically illustrated
in the accompanying Figures.
[0009] Figure 1 is a plan view of a paving stone according to the invention.
[0010] Figure 2 is a side view of Figure 1.
[0011] Figure 3 is a bottom view of Figure 1.
[0012] Figure 4 shows a first embodiment of part of a pavement formed of stones according
to Figures 1 - 3, which are laid in a so-called English bond.
[0013] Figure 5 shows a second embodiment of a pavement formed of stones according to Figures
1 - 3, which are likewise laid in a so-called English bond.
[0014] Figure 6 shows a second embodiment of a stone according to the invention.
[0015] Figure 7 is a side view of Figure 6.
[0016] Figure 8 is a bottom view of Figure 6.
[0017] Figure 9 shows part of a pavement formed of stones according to Figures 6 - 8, which
are laid in a so-called English bond.
[0018] Figure 10 shows a second embodiment of a pavement formed of stones according to Figures
6 - 8, which are likewise laid in a so-called English bond.
[0019] Figure 11 shows a further embodiment of a pavement formed of stones according to
Figures 1 - 3.
[0020] The stone illustrated in Figures 1 - 3 is a paving stone, which is preferably made
of concrete.
[0021] In this embodiment the length 1 of the paving stone 1 is 150 mm, the width b is 50
mm and the thickness d is 75 mm.
[0022] For those skilled in the art it will be apparent that these stones can be laid in
the usual manner in a so-called stretching bond and in a twilled bond without any
problem.
[0023] As is furthermore illustrated in Figure 4, the stones may also be laid in a so-called
English bond, wherein in one block of stones three stones are disposed parallel to
each other and wherein in an adjacent block likewise three stones are disposed parallel
to each, whereby the stones in said second block extend perpendicularly to those in
the first block, however. This arrangement can be realised because the width of the
stones is equal to three times the length of a stone.
[0024] As is illustrated in Figure 5 the stones may also be laid in an English bond, however,
when the stones are turned about their longitudinal axes through an angle of 90 degrees
from their position shown in Figure 4, so that in that case the sides of the stones
in Figure 4 will form the upper surfaces of the stones.
[0025] Since the thickness d of the stones amounts to half the length 1 of the stones it
is now possible, as will be apparent from Figure 5, to lay two stones in parallel
relationship in each block. Furthermore it will be apparent that in the position of
the stones shown in Figure 5 said stones can also be laid in a stretching bond of
in a twilled bond.
[0026] It will be apparent that in this manner, by using the dimensioning according to the
invention, the number of possibilities of laying various types of bond with the stones
according to the invention has been doubled compared to the number of possibilities
which has been usual up to now.
[0027] Figures 6 - 8 show another embodiment of a stone according to the invention. The
stone to has a length 1 of 200 mm, a width b of 50 mm and a thickness d of 66 mm.
[0028] As will be apparent from Figures 9 and 10, also in this case the stones can be laid
in two types of block bond, viz. in a first block bond, wherein the sides having a
width b form the upper sides of the stones and wherein each block comprises four stones
extending parallel to each other, and a second block bond, wherein the sides of the
stones having a thickness d of 66 mm form the upper sides of the stones and wherein
three stones extend parallel to each other in a block.
[0029] Of course the block bonds shown in Figures 4 - 5 and Figures 9 - 10 respectively
can also be combined with each other in any desired manner to form a pavement, e.g.
as illustrated in Figure 11 for the above-described stones 1.
[0030] As is furthermore illustrated in Figure 11 the same stones (possible cut in half)
can also be used in vertical position, so as to form a course of headers or an intermediate
course between the blocks.
[0031] Furthermore it will be apparent that in the two above-described positions of the
stones it is also possible to lay e.g. a stretching bond of a twilled bond.
[0032] An efficient use is made in particular of stones which are made in the manner described
in Dutch Patent Application 8502484, so that the stones have bevelled edges all around.
