Description
BACKGROUND OF THE INVENTION
The present invention relates generally to constructional elements
useful in the assembly of walls, especially translucent partition
walls and other like structures. Such partition walls are used to
define the boundaries of a place or room or a part of it without
producing a narrowing psychological effect.
Several types of constructional elements or building stones for
partition walls are already known and used. Anyhow, if such
partition walls are built in a dusty surrounding ugly dark stripes
can often be seen during or after fog or rainy weather when
deposited dust has become wet by fog and rain and is only partly
washed away. There is an increasing tendency to avoid this annoying
aspect owing to the increasing air pollution in many parts of the
country.
It is an object of the present invention to provide a specially
shaped constructional element which will overcome the
aforementioned disadvantages of already existing partition
walls.
The constructional element resides in a solid geometrical form
which finds a basic application as a building block. However, as
will be apparent to any one skilled in the art, this geometric form
may be used in a wide variety of embodiments and applications.
SUMMARY OF THE INVENTION
An object of the invention is to provide a new constructional
element comprising at least two frusta of cones or pyramides having
axes inclined to each other and having a common base, partly
penetrating each other in a zone adjacent to said common base, each
of said frusta having a smaller terminal face parallel to said
base, said smaller terminal faces being aligned. Conveniently the
constructional element, according to the invention, comprises two
frusta which are mirror images to each other and so oriented that
the axes form an acute angle.
Advantageously the smaller terminal faces of all frusta have the
same shape and are separated in the zone adjacent to said smaller
terminal faces.
In accordance with a further embodiment of my invention, the
constructional element comprises at least three frusta, having axes
symmetrically arranged around a main axis being perpendicular to
the common base and passing the center of said base, the angles
formed between said axes and said main axis being identical.
According to a further feature of my invention, the constructional
element comprises a further frustum on that side of the base
opposite to the other frusta with a smaller terminal face of same
shape and size as the smaller terminal faces of the other frusta,
all terminal faces being oriented parallel to said base.
According to a still further feature of my invention the side faces
of said further frustum are aligned with the corresponding sides of
the other frusta, and the outer common side faces of the frusta
have four outer common side faces which are shaped as plane
congruent pentagons.
To facilitate the insertion of glass windows into an assembled
partition wall of constructional elements, according to my
invention, each of the upper inner side faces of two mirrorlike
frusta are provided with a straight notch, and both notches are
arranged in a plane perpendicular to the common base of said
frusta.
The novel features which are considered as characteristic for the
invention are set forth in particular in the appended claims. The
invention itself, however, both as to its construction and its
method of operation, together with additional objects and
advantages thereof, will be best understood from the following
description of specific embodiments when read in connection with
the accompanying drawing.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
In the drawing identical reference numerals identify identical
elements. Discussing now the drawing in detail and firstly the
embodiment illustrated in FIG. 1, it will be seen that reference
numeral 1 identifies a frustum of a pyramide and reference numeral
2 identifies another frustum of a pyramide, both frusta having a
common base 3. The axes 4 and 5 of the frusta 1 and 2 respectively
are inclined to each other and form an angle of about 60.degree..
Each of the frusta 1 and 2 has an upper terminal face 6 or 7
respectively. Both terminal faces 4 and 5 are smaller than base 3
and parallel to it. In a zone adjacent to said common base 3 both
frusta penetrate each other as shown by broken lines.
In FIG. 1 the intersecting lines between the two frusta are shown,
the one intersecting line facing the viewer is identified by
reference numeral 8, illustrated by an uninterrupted line. The
intersecting line on the back of the constructional element is
indicated by a broken line. Both intersecting lines are inclined to
base 3 which is in a horizontal position when used in walls. This
inclined position of the intersecting lines has the advantage that
dust falling in the region between the two frusta will not deposite
there but glide off or be washed away by flowing of rain drops.
FIG. 2 illustrates another embodiment of the invention. The
constructional element comprises two frusta of cones 11 and 12
having a common circular base 13. The axes 14 and 15 of both frusta
form an angle of about 60.degree..
The embodiments illustrated in FIGS. 1 and 2 are especially useful
for the assembly of partition walls.
Other embodiments of the invention shown in FIGS. 3 and 4 comprise
three frusta of cones or four frusta of cones respectively. These
embodiments are especially useful for column-shaped
constructions.
In the embodiment according to FIGS. 2, 3 and 4 all intersecting
lines between the frusta of cones are inclined to the horizontal
base 13 so that deposited dust will not remain there.
In the embodiment according to FIGS. 5 and 6 all intersecting lines
between the frusta of pyramides are inclined to the horizontal base
13 so that deposited dust will not remain there.
An assembled wall of constructional elements comprises a plurality
of identically shaped constructional elements arranged in several
lines one upon another having interstices or blank spaces between
neighboring frusta. In some cases it is desirable to insert glass
windows or other translucent materials between said frusta. In this
way it is possible to achieve interesting architectonic and
aesthetical effects especially if plates of colored translucent
material are used.
FIG. 7 illustrates a constructional element, according to the
invention, which is provided with straight notches or recesses 16
to facilitate the insertion of glass windows between neighboring
frusta. The glass windows or sheets of other suitable material can
be fixed there by known adhesives. The recesses 16 are arranged
parallel to adjacent edges of the frusta.
Whereas FIG. 7 represents a modification of an embodiment according
to FIG. 1, FIG. 8 represents an analogous modification of an
embodiment according to FIG. 2. The notches or recesses 17 are
parallel to the adjacent generatrix of the respective cone.
FIG. 9 particularly indicates the combination of three frusta of
pyramides. Two frustra having axes 24 and 25 are composed according
to FIG. 1. The third frustum 20 having an axis 21 is situated on
that side of the base which is opposite to the other frusta. The
side faces 26' of said third frustum 20 are aligned with the
corresponding adjacent sides 26" of the other two frusta so that
the resulting side faces 26 being composed of faces 26' and 26" are
plane congruent pentagons.
Turning to FIG. 10 a part of a partition wall structure is
illustrated to demonstrate the utility of the subject invention. A
slightly modified arrangement of constructional elements according
to the invention is illustrated in FIG. 11. The abutting faces of
adjacent constructional elements, especially the terminal faces,
are provided with a suitable adhesive to fix the elements within
the wall.
The complete element, would, of course, be manufactured as an
integral unit by any of the known methods using any known and
suitable materials.
Many possible modifications will become apparent from the foregoing
without departing from the spirit of the present invention.
However, the foregoing disclosure is presented in an illustrative
sense rather than a limiting sense and the appended claims are
relied upon to define the scope of the present invention.
