Joint arm awning
Abstract
In a joint arm awning comprising joint arms disposed on a

Claims
What is claimed is:
1. A joint arm awning comprising joint arms (6) disposed on a
support pipe (1), with an awning fabric extending between a
drop-out pipe (5) and a fabric roll which is disposed on a fabric
roll shaft (3) and with the portion of the fabric roll and the
drop-out pipe (5) being covered by a cover when the drop-out pipe
(5) is retracted, wherein the cover (9) is corrugated or ribbed or
serrated cross-sectionally and longitudinal grooves thus formed are
substantially parallel to the support pipe (1).
2. A joint arm awning according to claim 1, wherein the cover
consists of stainless steel sheet.
3. A joint arm awning according to claim 1, wherein reinforcement
elements are disposed on the upper side of the cover (9) at a
distance from, and parallel to, each other, which overlap the cover
(9) and are fixed at the front in a groove of the cover (9).
Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The invention relates to a joint ann awning comprising joint
arms disposed on a support pipe, with an awning fabric extending
between a drop-out pipe and a fabric roll which is disposed on a
fabric roll shaft and with the portion of the fabric roll and the
drop-out pipe being covered by a cover when the drop-out pipe is
retracted.
[0003] 2. Background Art
[0004] A joint arm awning of the generic type is known for instance
from U.S. Pat. No. 5,839,491.
[0005] For protection of joint arm awnings in the retracted
condition against environmental exposure and soiling, it is known
to retract the awning fabric into a box which entirely encloses the
arms, the fabric roll shaft and the joint arms in the retracted
condition.
[0006] It is further known to provide rain-proof blinds which
extend for instance in a curved cross-sectional configuration
around the fabric roll shaft and the fabric roll, leaving an outlet
aperture for the awning fabric. The underside of this blind is
semi-circular, its diameter corresponding to the diameter of the
rolled up fabric roll so that the awning fabric, when extracted,
slides on the inside of the blind.
[0007] A drawback of these known covers resides in that a scraping
effect is exercised on the surface of the fabric when it slides
along the cover and dots of soil are distributed on the surface of
the awning fabric. Furthermore, the known solutions have the
drawback that rainwater falling down will be deviated not only
forwards, but also backwards toward the wall of a house, giving
rise to humidity and soiling.
SUMMARY OF THE INVENTION
[0008] It is an object of the invention on the one hand to avoid
the technical drawbacks of conventional covers and on the other
hand to create an optically attractive design which stands out also
esthetically from known designs.
[0009] According to the invention, this object is attained in that
the cover is corrugated or ribbed or serrated cross-sectionally and
longitudinal grooves thus formed are substantially parallel to the
support pipe. Preferably, the cover consists of stainless steel
sheet.
[0010] In as much as the foregoing talks of a cover, this means a
box-type cover as well as a rain-proof blind which only partially
covers the awning.
[0011] The design according to the invention has the advantage that
only rolling line contact of the awning fabric with the cover takes
place, when the awning fabric slides on the inside so that the
scraping effect on the surface of the fabric is reduced and tiny
dirt particles deposit in the grooves.
[0012] Falling water does not flow off in a direction vertical of
the fabric roll shaft toward the wall of a house and therefore does
not splash on the wall, but is led away laterally through the
concavities, or its flow is braked so that the water drops
vertically downwards without contacting the wall of the house.
[0013] An especially attractive design is attained by the steel
sheet embodiment. The ribbed or corrugated design has the
additional effect of rigidifying the sheet so that steel sheet of
comparatively little thickness can be used. The stainless steel can
be used without a coating of paint, nevertheless defying weather.
This is ideal in particular when the whole awning frame is designed
for an appearance made of steel.
[0014] In keeping with an advantageous embodiment, it can be
provided that reinforcement elements are disposed on the upper side
of the cover at a distance from, and parallel to, each other, which
overlap the cover and are fixed at the front in a groove of the
cover.
[0015] Details of the invention will become apparent from the
ensuing description of a preferred embodiment, taken in conjunction
with the drawing.
BRIEF DESCRIPTION OF THE DRAWING
[0016] The drawing FIGURE is a sectional view through a joint arm
awning with a cover according to the invention.
DESCRIPTION OF THE PREFERRED EMBODIMENT
[0017] An awning seen in the drawing comprises a support pipe 1
which is mounted on a wall of a house by means of wall mountings
(not shown). Curved holders 2 are fixed to the support pipe 1 with
a fabric roll shaft 3 being mounted thereon to be driven in
rotation. An awning fabric roll (not seen in the drawing) is rolled
up on the fabric roll shaft 3 and, via a piping groove 4, the free
end of the awning fabric is connected to a drop-out pipe 5.
[0018] Furthermore, two joint aims 6 are mounted on the support
pipe, their free outer ends being joined via bends 7 to the
drop-out pipe.
[0019] Holders 8 are mounted on the support pipe 1, their upper
side extending around the fabric roll shaft 3 concentrically
thereof and at a distance therefrom. This is where a cover 9 is
fixed, the underside of which rests on the upper side of the
holders 8, correspondingly extending concentrically of the fabric
roll shaft, whereas the upper side of the cover 9 reaches further
forwards (to the right in the drawing) so that a passage 10 for the
awning fabric is formed between the two ends of the cover 9. Caps
11 are placed laterally on the cover 9.
[0020] The cover 9 is serrated or corrugated so that convexities 12
and concavities 13 originate, running in the longitudinal direction
of the fabric roll shaft 3.
[0021] As a result of the concavities 13 in the vicinity of the
rear 14 of the cover 9, water cannot flow off unimpeded towards the
wall of a house (to the left in the drawing), but is led off
laterally or at least its flow is braked.
[0022] On the inside where the concavities 13 appear as
projections, they ensure rolling line contact of the awning fabric
and preclude surface friction, with particles on the awning fabric
depositing in the concavities 13.
