Claims
What is claimed is:
1. A curtain rod of a design intended to be suspended over
substantial spans without supporting means between its ends by
providing high resistance to flexure in the vertical plane
comprising
a quadrangular cross section arranged in a generally diamondlike
orientation in which diagonally opposed corners are at the same
horizontal level,
supporting wings for supporting curtain suspension members
projecting horizontally from each of said diagonally opposed
corners and
guide means in the vicinity of the free ends of said supporting
wings for guiding the curtain suspension members.
2. A curtain rod as claimed in claim 1 wherein the rod is
rectangular in cross section.
3. A curtain rod as claimed in claim 2 wherein the rod is square in
cross section.
4. A curtain rod as claimed in claim 1 wherein hollow spaces in
said rod are filled with cores made of wood.
5. A curtain rod as claimed in claim 1 wherein in the operative
position at least one vertical rib extends from a vertical
corner.
6. A curtain rod as claimed in claim 1 having a wooden core around
which a coating, said supporting wings and said guide means are
injection molded.
Description
The invention relates to a curtain rod which can be freely
suspended. By being freely suspended it should be understood that
the rod can be suspended over substantial spans without supporting
means between its ends. The rod may be secured to the walls at its
ends by any suitable support means. One such means is disclosed in
my copending application 6411 filed Jan. 28, 1970.
Known curtain tracks are set into the ceiling of a room or fastened
directly thereto. They in fact reach a high position, but are often
unsuitable for modern and old room arrangements and
decorations.
Curtain supporting rods comprising a circular cylinder or tube or a
wooden pole are also known. Rings which hold the curtains so as to
be movable back and forth slide on to the tube or wooden pole. Such
curtain supporting rods would, in some cases, be suitable for
modern interior decoration, but they have a number of disadvantages
which render them unsuitable for modern usage:
1. They are not sufficiently inflexible and can therefore only be
used over narrow windows. They are unsuitable for modern windows
which are sometimes very wide.
2. The running qualities of the rings are quite inadequate. If
these were used, it would be necessary to dispense with all the
advantageous features of the modern plastics runners or
rollers.
3. A separate curtain rod is needed for each curtain.
4. With these curtain supports it is impossible for the curtains to
overlap at their ends.
5. The known curtain rods are unsatisfactory from the aesthetic
point of view.
The object of the invention is to provide curtain supporting rods
which fulfil the requirements of old and modern interior
decoration, are inflexible particularly in a horizontal and
vertical direction, but which make it possible, nevertheless, to
benefit from the advantages of modern curtain tracks and suspension
members.
This problem is solved in accordance with the invention in that the
curtain rod is highly inflexible in a vertical plane in an
operative position and in that supporting faces having guide means,
in the vicinity of their free ends, for curtain suspension members
extend therefrom on both sides. In this connection, the dimensions
of this curtain support are in cross section considerably larger
than the curtain suspension members in use.
Other advantages and features of the invention are shown in the
following description of preferred embodiments.
In the drawings:
FIG. 1 shows a cross section of a first embodiment of a broken-away
curtain supporting rod shown in perspective,
FIG. 2 shows the same cross section through a second
embodiment,
FIG. 3 shows the same cross section through a third embodiment,
FIG. 4 shows a cross section through a fourth embodiment having
curtain hooks and support means,
FIG. 5 shows a cross section through a fifth embodiment,
FIG. 6 shows an enlarged detail of a sixth embodiment,
FIG. 7 shows a cross section through a seventh embodiment,
FIG. 8 shows a cross section through an eighth embodiment.
A curtain rod 11, as shown in FIG. 1, comprises a hollow tube 12 of
quadrangular cross section when seen in its operative position. As
can be seen, the tube 12 is placed diagonally so that the corner 13
is at the top, the corner 14 at the bottom, and the corners 16 and
17 are located on the same level on the left and right. In the tube
12 there is provided a hollow space 18 which can be filled with a
reinforcement made of wood, foam material or the like. A first
supporting wing 19 which is integral with the tube 12 and a
vertical guide rib 21 extends to the left from the corner 16.
From the corner 17 extends a second supporting wing 22 which has a
narrow section 23 in the vicinity of its free end.
Another vertical guide rib 24 is supported on this wing 22, extends
above and below the latter and has an undercut groove 26 by which
the guide rib 24 can be supported. The supported guide rib has the
advantage that it makes smooth guiding possible. Even when the
curtain rod 11 is cut at a particular point, the guide rib 24 also
absorbs the impact caused by cutting. A supported guide rib 24 also
makes it possible for the tube 12 and the supporting wings 19 to be
made of metal which does not have such good running properties as a
guide rib 24 made of plastics material. Finally, the tube 12 and
the supporting wings 19 and 22 can for example be manufactured in
an aluminum color and the guide rib in a golden color, thereby
producing a particularly decorative effect. Usually the guide rib
21 is only integral with the supporting wing 19 if the entire
curtain rod 11 is made of plastics material.
In the embodiment according to FIG. 2 a core 27 can be made of a
wooden rod or a metal tube. This core 27 is enclosed by a moulded
plastics material and has a shape similar to the embodiment shown
in FIG. 1. In addition there are provided an upward projecting rib
28 and a downward projecting rib 29. Moreover, there is
considerable stiffness in flexure in the vertical plane whereas, as
in the first embodiment, the supporting wings 19 and 22 offer
considerable resistance to flexure in a horizontal plane and also
have points of attachment for guiding means, as shown for example
by the guide ribs 21 and 24.
As in the first embodiment, it is also possible in this case (and
in the other embodiments yet to be described) to support two
curtains on a single curtain rod, thereby giving such a curtain
track a particularly pleasing appearance.
In the embodiment according to FIG. 3 the core 27 has a trapezoidal
shape, and can again consist of wood or metal. It is enclosed by an
injection-moulded trapezoidal rod 12. The side 31 of minimum
surface area points upwards, whereas the sides, 32 and 33 are
relatively large. A lower side 34 can be omitted and the core 27
inserted from below so that it is visible.
Finally, the supporting wing 19, the sides 32, 31 and 33 and the
supporting wing 22 can be produced as one integral piece and the
side 34 as a base plate to be attached additionally. In the
embodiment according to FIG. 4 the curtain rod is cross shaped. The
horizontal ribs represent the supporting wings 19 and 22. A
downward projecting rib 36 bears a guide means in the form of a
guide rib 37 while a holding rib 39 is moulded to an upward
projecting rib 38, said holding rib fitting together with the upper
part of the rib 38 into a T-shaped recess 41 of an iron section 42
which is driven into a wall and secures the curtain rod 11 by means
of a screw 43.
The supporting wing 22 extending to the right bears an inner track
44, the upper wall 46 of which is an extension of the wing 22 and
the vertical walls 47 and 48 support at their free lower ends
horizontal ribs 49 and 51 between which a runner groove 52 is left
open.
It can be seen basically from this embodiment that the new curtain
rod can be used together with front runners 53, outer rollers 54
and with the inner track 44 having inner rollers or runners. The
inner track 44 can also be used as a double outer track because
outer rollers 54 can be guided, for example, along the wall 47 and
rib 49.
In the embodiment according to FIG. 5 the rod consists of two
semidome sections 56 and 57, the sides 58, 59 and 61, 62 of which
are integral with the supporting wings. The two semidome sections
56 and 57 are spot welded at 63 and 64 and have a strip of metal 66
extending transversely through the hollow space 18 and as far as
between the sides 58, 61 and 59, 62. The sides 58 to 62 have
flanges 67, 68, 69 and 71 projecting upwards or downwards. The
whole construction can be covered in a plastics coating 72.
In the embodiment according to FIG. 6 the semidome sections or
their sides do not need to be coated with a plastics material. They
can for example, be made of a lightweight metal which is
advantageous from the aesthetic point of view. In this case it is
possible to use the guide rib 24 both for connecting the two
semidome sections together and, at the same time, acting as a guide
means for curtain hooks.
In the embodiment shown in FIG. 7 the rod 12 is made of a plastics
material while the core 27 takes the form of a metal tube or a
wooden insert. The ribs 28 and 29 are indicated by broken lines to
show that they can be omitted.
In the embodiment according to FIG. 8 the supporting wings 19 and
22 can be seen again, with their guide ribs 21 and 24. Two cores 27
in the form of wooden rods with a box-shaped cross section are
inserted in a vertical direction. These cores 27 are covered by a
plastics coating 72. Their arrangement with regard to the neutral
fibers which can be seen in the longitudinal axis of the curtain
rod depending on stress, produces a surprisingly high resistance to
flexure in a vertical direction. Bending in a horizontal direction
is mainly absorbed by the supporting wings 19 and 22. The cores 27
can also be integral in the vertical direction.
As can be seen in the drawings, care has been taken to maintain a
symmetrical form for purely mechanical and static reasons as well
as for aesthetic and manufacturing purposes.
