Description
[0001] The invention relates to a molded block according to the
preamble of claim 1.
PRIOR ART
[0002] U.S. Pat. No. 4,792,257 has disclosed a set of paving stones
which comprises a paving stone which is square in plan view and
whose lateral, planar faces have rounded portions running toward
the vertical side edges which, in plan view, are designed as a
curve with radii of curvature decreasing constantly toward the
vertical side edges. Rounded portions of this type are referred to
as "clothoids".
[0003] Such a "standard block" with a square base in plan view is
supplemented in this prior art by a "1/2 block" with half the base
and a "1{fraction (1/2)} block" with 1.5 times the base. Both
supplementary blocks again have, in their corner regions,
clothoidal rounded portions in plan view. Such clothoids may be
present on one or more side faces.
[0004] The side faces and the upper and lower faces are otherwise
formed as planar faces. The circumferential edge regions can in
this case be designed to be irregularly broken. In this known set
of blocks, the height of the paving stones is always considerably
lower than the edge length of the upper, square face of the
standard block. This ratio is about 2.5.
[0005] DE 33 25 752 has disclosed a concrete paving stone which has
approximately the geometric shape of the 1{fraction (1/2)} block of
U.S. Pat. No. 4,792,257, that is to say it is an elongate
parallelepiped. In this case, however, the longer side edge in the
paving stone according to DE 33 25 752 is about three times as long
as the shorter side face. The height of this paving stone includes
a further dimension which is lower than the width of the shorter
side face. The special feature in this prior art resides in the
fact that the block form can be laid differently. In this case,
because of the different dimensions between block height and block
width, mixed laying is not possible, since a paving stone rotated
through 90.degree. about the longitudinal axis forms a higher
laying height because of its width. Such a paving stone rotated
through 90.degree. gives a non-planar surface structure in its
laying pattern, because of the clothoid being laid at the top,
since the clothoid shape comes to lie in the upper face. As can be
seen from the figures of DE 33 25 752, different surface structures
can therefore be laid with a molded block. However, mixed laying is
not possible.
OBJECT AND ADVANTAGES OF THE INVENTION
[0006] The invention is based on the object of proposing a molded
block which, on account of its shape, provides the possibility of
flexible laying. At the same time, both planar and non-planar faces
are to be produced, which can also be configured in mixed form.
[0007] This object is achieved by a molded block according to claim
1.
[0008] Advantageous and expedient developments of the molded block
specified in the main claim are presented in the subclaims.
[0009] The invention is based on the finding that a planar or a
profiled surface structure of a paving-stone covering can be
implemented with, for example, only one molded block if the molded
block has different geometric structures on its outer faces, which
can be used as desired in order to configure the paving-stone
surface. If, in particular, the paving stone is used in the form of
a cube, that is to say with side edges of equal length, then
different configuration of the sides of the cube can lead to the
configuration of different surface structures. In this case, the
present invention additionally makes use of the feature of the
geometric modification of a cube face. This is done in such a way
that either a planar cube face is structured in its side contour,
or that a cube face intrinsically has a two-dimensional or
three-dimensional shape. As a result of these measures, by rotating
the cube about a horizontal or a vertical axis of rotation, in each
case a different "cube surface" can be used as the upper surface to
be walked on, the respectively different structures of these faces
leading to a very different appearance of the paving-stone
covering. In particular, planar faces and curved faces can be
selected as the upper face of a respective molded block, and can in
each case be combined with one another.
[0010] In a development of this basic idea, a so-called "double
cube" or "twofold cube" can also be used, which corresponds to the
dimensions of two basic elements laid beside each other. This
twofold cube can also be laid differently by its being rotated
through 90.degree., for example, about its horizontal longitudinal
axis. For this purpose, however, the block height and the shorter
broad side of the block must agree in their length dimension, in
order to be inserted into the grid pattern without any projection,
that is to say at the same laying height.
[0011] Also advantageous is the use of a fourfold cube, that is to
say the basic block is joined together four times about a vertical
longitudinal axis, it being possible for such a block to be rotated
only about its vertical mid-axis in the composite surface.
[0012] In a particular refinement of the invention, the faces of
such block shapes are provided with a "clothoid", that is to say
the intrinsically planar side face has a rounded portion toward the
edge region whose radius of curvature decreases constantly toward
the side edge. These clothoids can be present singly or in
duplicate on each side face, the result being a very different
laying pattern. If, according to the invention, wedge blocks are
also added to such a building-set arrangement, the result is
overall a paving-stone building set which permits flexible laying.
In this case, the laying can be designed to be straight or curved,
it being possible, in the case of a curve, for the corners aligned
toward the center of the curve to be sharpened by one or two
clothoids being arranged at such points.
[0013] If, in this connection, laying examples are provided, then
the result may be surfaces structured very differently in a
straight or a curved shape, in particular with the cube
structure.
[0014] Further details of the invention are illustrated in the

DESCRIPTION OF THE EXEMPLARY EMBODIMENTS
[0029] FIG. 1 shows the standard block, as it is known, or basic
block 1, which has the basic structure of a cube with the
respective equal edge length L. The cube has an upper planar
horizontal face 2, a lower planar and horizontal supporting face 3
and four vertical side faces 4 to 7. The upper corner points of the
cube are designated by reference symbols 8 to 11, the lower corner
points of the cube are designated by reference symbols 12 to 15.
Similarly, the vertical connecting lines through the corner points
8 to 15 are designated by the reference symbols 16 to 19.
[0030] The plan view of the cube-shaped block form of FIG. 1a is
illustrated in FIG. 1c.
[0031] FIG. 1a and FIG. 1c reveal a first rounded portion 20 of the
side face 5, that is to say the side face 5 has a rounded portion
20 which is directed toward the vertical connecting line 16 and
whose radius of curvature R changes continuously toward the corner
region. Such a rounded portion is designated a clothoid, which in
the further text is designated by the general reference symbol K.
The shape of such a clothoid is described most extensively in terms
of its extent and dimensions and its arrangement in the earlier
U.S. Pat. No. 4,792,257. Reference is hereby expressly made to this
document. In this regard, this document is incorporated in the
present application. In particular, the clothoids may have
different dimensions, that is to say the beginning of the clothoid
can extend over different length sections on the side wall.
[0032] FIGS 1a, 1c further reveal that the side face 7 opposite the
side face 5 has two rounded portions 21, 22, which are likewise
formed as clothoids K. In this case, the clothoid 21 extends from
the planar side face 7 in the direction of the corner point 11 and
vertical side edge 19 and, as it increasingly approaches this side
edge, has a radius of curvature R which becomes smaller and
smaller. The same applies, in mirror-image fashion in relation to
the vertical mid-plane 23, with regard to the rounded portion or
clothoid 22.
[0033] The clothoid 22 can also extend on the side face 6 toward
the corner point 10. This is shown dashed by 22'. In the region of
the vertical connecting line 17 there is no rounded portion, so
that this connecting line 17 simultaneously forms the block side
edge 17.
[0034] Similarly, there could be a clothoid on the side face 4 as
well, the rounded portion extending either toward the corner point
8 or toward the corner point 11.
[0035] As a result of the clothoids 20 to 22, the cube form of the
basic block 1 is therefore somewhat modified in terms of its
structure, that is to say corner regions are cut off over a large
area by the rounded portion.
[0036] The cube structure of the paving stone of FIG. 1a has
vertical planes of symmetry 23, 24. FIG. 1a reveals horizontal axes
of rotation 25, 26 and a vertical axis of rotation 27 through the
center of symmetry 28.
[0037] The cube-shaped block form of FIG. 1a makes it possible to
rotate this block in all directions about the axes of rotation 25,
26, 27, in each case through 90.degree. or 180.degree..
[0038] If, for example, the block of FIG. 1a is rotated in the
clockwise direction about the horizontal axis of rotation 25 (arrow
29), then the result is the block form of FIG. 1b. The rear side
face 7 becomes the upper face 7', the upper face 2 becomes the side
face 2' and the front side face 3 becomes the lower side face 3'.
If the paving stone of FIG. 1 has an upper planar face 2, then in
the event of a rotation through 90.degree. about the axis of
rotation 25, this face becomes the upper face in relation to a
profiled surface 7' having the two clothoids 21, 22. By this means,
the upper structure is beveled off in two directions by the
clothoids 21, 22 in the direction of the side edges. This imparts a
spatial two-dimensional structure to the upper face 7'.
[0039] The exemplary embodiments 2a to 2c deal with a twofold block
or double block 30. If the block form of FIG. 1a is doubled by the
length 2L, then the result is the block form of FIG. 2a with a
longer side edge 2L, with a shorter side edge L and a height L. The
paving stone of FIG. 2a has an upper planar face 31, a lower
supporting face 32 and vertical side faces 33 to 36. The front face
34 again has a rounded portion 20 in the form of a clothoid K, the
rear face 36 has two rounded portions 21, 22 in the form of a
clothoid K. These clothoids correspond to the description of FIGS.
1a, 1c. According to the exemplary illustration of FIG. 2c, the
clothoids can also be located on the side face 35 as clothoids
22'.
[0040] Since the side faces 33, 35 substantially have a square
cross section, the block form of FIG. 2a can be rotated about a
horizontal longitudinal mid-axis 25' (arrow 29). As a result, the
rear side 36 comes into the upper position according to FIG. 2b, so
that the rounded portions 21, 22 formed as clothoids again appear
as the upper face according to the illustration in FIG. 2b. If an
equally high surface of the blocks is desired in spite of the
rotation of such blocks, the twofold block of FIG. 2a can merely be
rotated in 90.degree. steps about the horizontal axis of rotation
25'.
[0041] FIG. 2b shows, in a form offset to the right, the variant
having a clothoid 22' on the side face 35.
[0042] If the block form of FIG. 2 comprises two cube structures
according to FIG. 1 located beside each other, then in the
exemplary embodiment of FIG. 3, the effect is of four basic stones
laid beside one another in their cube form. This fourfold block 37
accordingly has, in its square plan view of FIG. 3, an edge length
of 2L in each case. The upper planar face is designated by 38, a
lower, invisible supporting face is designated by reference symbol
39. The vertical side faces are designated by 40 to 43. As already
described in FIGS. 1 and 2, the front lateral face 41 has a lateral
clothoidal rounded portion 20. Similarly, the opposite vertical
side face 43 has rounded portions 21, 22 which point toward both
corner regions and are likewise of clothoidal design.
[0043] Likewise, as illustrated by way of example, the side face 42
can alternatively have a clothoid 22'. The height of the fourfold
block 37 illustrated in plan view is again the basic dimension
L.
[0044] In order to form an equal height layer of a laid surface,
the fourfold block of FIG. 3 can be rotated through 90.degree. or
180.degree. only about the vertical axis of rotation 27. Of course,
it is also possible for the twofold block 30 to carry out this
rotational movement.
[0045] The implementation of the clothoid form 20 to 22 can be
carried out on any desired side face or surface. A modified rounded
portion or bevel is also conceivable.
[0046] The block forms of FIGS. 2 and 3 can also be placed on edge
to form an edge stone, so that these project above the remaining
paving-stone covering by a length L. This makes a simple edge
border possible with the same block form. Here, too, the block
forms can be rotated in such a way that the upper face is designed
to be more rounded or more flat.
[0047] The illustration of FIG. 4 shows a first laying example of
the block forms of FIG. 1a and FIG. 1b.
[0048] If the standard block 1 in an arrangement according to FIG.
1a is laid with a planar upper face 2, then this is illustrated in
the top row 44 of FIG. 4. Each normal block 1 within the row 44 can
still be rotated in the clockwise direction or the counterclockwise
direction about its vertical axis of rotation 27, corresponding to
the arrow representation 45. By this means, the arrangement of the
clothoids 20 to 22 can be shifted into each corner region. The
arrangement of the clothoids 20 to 22 or else other clothoids can
be varied in terms of their position on the basis of such
rotational movements.
[0049] In the next row 46, the block form 1' corresponding to the
illustration of FIG. 1b is shown. In this case, the upper face 7'
is visible, so that the rounded portions or clothoids 21, 22 form a
rounded upper face. Accordingly, a structured three-dimensional
upper face 7' is arranged in row 46, beside the planar surface in
row 44.
[0050] The next row 47 can again be formed like the row 44. The
lowest row 48 shows a rotation of the standard blocks 1' in row 46
about a vertical axis of rotation 27'.
[0051] Of course, the standard blocks 1, 1' with a planar surface
or rounded surface 7' can also be varied as desired within a
row.
[0052] In the exemplary embodiment of FIG. 5, the block forms of
FIGS. 1 to 3 are combined. The upper row 49 shows the twofold block
30 of FIG. 2a, the row 50 lying alongside shows the block form 30'
of FIG. 2b, that is to say a block form of row 49 rotated through
90.degree. about the horizontal longitudinal axis.
[0053] Row 51 shows the block form analogous to the row 44 in FIG.
4, row 52 shows an arrangement analogous to the row 48 in FIG. 4,
but with two basic blocks 1' located beside each other in each
case.
[0054] Finally, the lower row 53 illustrated in FIG. 5 shows the
block form 37 of FIG. 3.
[0055] It goes without saying that the block forms corresponding to
the illustration of FIG. 4 can be varied as desired. In this case,
both a running unit with offset joints and a crossing unit with
mutually crossing joints can be established. In addition, the
twofold blocks 30 and the fourfold blocks 37 can also be placed on
edge in order to form edge boundaries.
[0056] Variants of the standard block 1, 1' of the FIGS 1a to 1c
are illustrated in FIGS. 6a to 6e with the capital letters A to E.
In this case, these may be a plan view of a corresponding
cube-shaped standard block 1 whose clothoids A are arranged on
different side faces. If the upper face is again designated by 2,
the vertical side faces by reference symbols 4 to 7, the result is
the variations illustrated. In FIG. 6a, the side faces 4, 6, 7 have
a clothoid K running around in the clockwise direction in each case
in the corner regions.
[0057] A right angle of a corner region without a clothoid is
marked appropriately. FIG. 6b shows a clothoid K on the side faces
4, 5 and 6, which are arranged to run in opposite directions on the
side faces 5 and 6, that is to say in the counterclockwise
direction, and in the clockwise direction on the side face 4. The
exemplary embodiment of FIG. 6c shows a clothoid K in the region of
the side face 5 with otherwise three rectangular corner regions.
FIG. 6d shows a clothoid K on the side face 5 and on the side face
7, arranged so as to run in the counterclockwise direction.
Finally, FIG. 6e shows a clothoid K on the side face 4 and on the
side face 6, running in the clockwise direction.
[0058] The edge length L of the cube 1 can, for example, have a
dimension of 9.5.times.9.5.times.9.5 cm. In order, in particular,
to lay areas in accordance with the illustration of FIG. 7,
additional block forms according to FIGS. 6j to 6i are provided,
and are designated by the letters J, H and I. The block form of
FIG. 6j can have any outline structure of the block forms of FIGS.
6a to 6e. In FIG. 6j, it is illustrated in a similar way to FIG.
6c, with a clothoid K on the side face 5.
[0059] If the side edge L is for example L.apprxeq.95 mm in the
block forms previously specified, then the block form of FIG. 6j
can have an edge length of the cube of L'.apprxeq.80 mm. This
special block form of FIG. 6j is designated a "small block" 54. The
block form of FIG. 6h again relates to a special block as a first
wedge block 55, which has an excess length L.sub.1.apprxeq.100 mm
and a shortened width L.sub.2.apprxeq.75 mm, with a height L
defined for all the blocks in the building set. The plan view of
FIG. 6h accordingly shows a block 55 which is slightly rectangular
in outline.
[0060] If, in FIG. 6h, the vertical side edges are again designated
by the reference symbols 4 to 7, then the two side faces 4 and 6
are designed to be wedge-shaped and, nevertheless, have clothoidal
rounded portions K running in the clockwise direction in their
corner regions. The planar side face 4 forms a first wedge angle
.alpha.1.apprxeq.2.5.degree., the planar side face 6 forms a second
wedge angle .alpha.2.apprxeq.3.0.degree- .. The opening of the
wedge angle is oriented in the same direction, that is to say
downward in FIG. 6h.
[0061] The upper side face 7 also has a clothoid K running in the
clockwise direction.
[0062] The second wedge block 56 is a further supplementary block
with the same special length L.sub.1 as the wedge block of FIG. 6h,
it being possible for L.sub.1 to be approximately equal to 100 mm.
The further special length L.sub.3 is designed, for example, at 87
mm in the system. Here, too, the side faces 4 and 6 have a first
wedge angle .beta.1.apprxeq.1.5.degree. and a second wedge angle
.beta.2.apprxeq.1.5.degree.. The clothoids K running in the
clockwise direction are again arranged in the corner region of the
side faces 4, 6, the clothoid on the side face 4 being arranged
opposite the wedge angle .beta.1.
[0063] The block forms illustrated in plan view in FIGS. 6a to 6i
are reproduced in a laying example according to FIG. 7 in a curved
laying pattern. In this case, all the block forms are designated by
the corresponding capital letters. It can be seen from this that
the block forms can be rotated in a [lacuna] in each case about a
vertical mid-axis of rotation, in order to come into an
appropriately desired position. This desired position can result
from the fact that the corner regions adjoining one another on the
inside of a curve adjoin one another rather without a clothoid than
with a corresponding clothoid. The blocks can therefore be rotated
appropriately about their vertical axis of rotation in order to
come into a desired position. For example, two to three clothoids
are laid together at the lower butt point, in order to form a
curved laying pattern. In this case, the longer wedge blocks H and
I can be laid both toward the center of the circle and in the
transverse direction with respect to this. By this means, using
cube-shaped and slightly rectangular and wedge-shaped blocks, a
particularly well-structured curve shape can be laid. If the curved
pattern illustrated in FIG. 7 is desired, it is possible, for
example, for a template, for example of degradable filter paper, to
be laid underneath, on which the blocks are laid in the form
illustrated. of course, the individual blocks must be marked
appropriately in some form.
[0064] Illustrated in the lower region of FIG. 7 are two curved
rows, with appropriate dimensioning specified by way of
example.
[0065] The invention is not restricted to the exemplary embodiments
illustrated and described. Instead, it also comprises all
developments by those skilled in the art within the context of the
protective claims. In particular, the clothoids can also have a
modified shape, clothoids being quite particularly outstanding in
terms of their configuration.
[0066] In addition, the block forms illustrated in FIG. 7 can be
configured to be planar, in accordance with the plan view of FIGS.
6a to 6i. By means of appropriate rotation of the blocks about a
horizontal axis of rotation, a physically rounded surface with
clothoids on the upper side can also be produced. This provides an
appearance with a planar and structured upper face. Furthermore,
all the circumferential block edges can be wholly or partly broken
or rounded, in a way similar for example to the illustration in
FIGS. 1b to 3b of U.S. Pat. No. 4,792,257.
