Sun room awning or the like
Abstract
In a sun room awning, comprising a rotating-drivable roll bar
with an awning cloth, lateral guide rails for the awning cloth, and
tensioning straps as well as tautening means for the awning cloth
that engage at the front end of the awning cloth or at a drop-out
rail, it is provided that the tensioning straps are designed
elastic in the longitudinal direction, at least in sections, to
exert tension onto the awning cloth in order to achieve a
construction ensuring a taut, visually attractive fit regardless of
the extended position of the awning cloth.

Claims
What is claimed is
1. A sun room awning or the like, comprising a rotating-drivable
roll bar with an awning cloth, lateral guide rails for the awning
cloth, and tensioning straps as well as tautening means for the
awning cloth that engage at the front end of the awning cloth or at
a drop-out rail, wherein the tensioning straps (1) are designed
elastic in the longitudinal direction, at least in sections, to
exert tension onto the awning cloth (5).
2. An awning according to claim 1, wherein the tensioning straps
(10) are installed pretensioned.
3. An awning according to claim 1, wherein the tensioning straps
(10) behave elastically up to a certain stretching point and are
essentially inelastic after this stretching point has been
exceeded.
Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention is directed to a sun room awning or
the like, comprising a rotating-drivable roll bar with an awning
cloth, lateral guide rails for the awning cloth, and tensioning
straps as well as tautening means for the awning cloth that engage
at the front end of the awning cloth or at a drop-out rail.
[0003] 2. Background Art
[0004] The winding diameter of the tensioning straps is larger when
the awning is wound up than when the awning is unwound, just like
the cloth roll itself. To compensate for the different paths of
travel that result from the different winding diameters, tightening
elements are commonly used that incorporate spring elements. Spring
elements of this type make the assembly rather complex and increase
the manufacturing costs.
[0005] To remedy this situation, provision is made according to DE
100 33 419 to transport the awning cloth in its direction of
extension along inherently stiff push straps.
SUMMARY OF THE INVENTION
[0006] The present invention has as its object to make possible a
design without tightening elements while continuing the use of
tensioning straps, that ensures a taut, visually attractive fit
regardless of the extended position of the awning cloth.
[0007] This object is met according to the invention in such a way
that the tensioning straps are designed elastic in the longitudinal
direction at least in sections to exert a tension onto the awning
cloth. Provision may advantageously be made for the tensioning
straps to be installed pretensioned so that a tension effect is
exerted onto the awning cloth at all times.
[0008] The inventive solution eliminates the need for additional
tightening elements because the tensioning straps are designed
springy elastic in themselves along the entire length or along
sections thereof.
[0009] The tensioning straps may also be composed of a fabric,
knitted material, or weave, which behaves elastically only to a
certain stretching point and is essentially inelastic after this
stretching point has been exceeded. The awning in its extended
position can thus be pulled out stiffly due to the blocking of the
gear or motor, and the result is a cloth that, when stressed by
winds or other stresses, is very taut.
[0010] The invention will be explained in more detail below, based
on a preferred embodiment in combination with the drawing.
BRIEF DESCRIPTION OF THE DRAWINGS
[0011] FIG. 1 shows a schematic side view of a sun room awning in
its retracted position,
[0012] FIG. 2 shows an illustration according to FIG. 1 in the
extended position,
[0013] FIG. 3 shows a schematic top view of the sun room awning it
its extended position, and
[0014] FIG. 4 shows a schematic section through the lateral guide
region of the drop-out rail.
DESCRIPTION OF THE PREFERRED EMBODIMENT
[0015] A sun room awning shown in the drawing comprises a
rotating-drivable roll bar 1 with an awning cloth roll 2, which is
rotating-drivable in the direction of the double arrow 3, namely
for retraction in the direction of the upper partial arrow in FIG.
1 and FIG. 2, respectively, and for retraction in the direction of
the lower partial arrow in FIG. 1 and FIG. 2, respectively.
[0016] The front end 4 of the awning cloth 5 is fixed in a piping
groove 6 of a drop-out rail 7, which is guided via a lateral slider
8 on each side inside lateral guide rails 9.
[0017] An elastic tensioning strap 10 engages on each slider 8, and
this tensioning strap 10 is deflected in the region of the outer
end of the guide rail 9 by means of a deflection roller 11 by
180.degree. and connected to the slider 8 and drop-out rail 7 by
means of a piping 12. In the region of the inner end of the guide
rail 9 a second 90.degree. deflection roller 13 is provided,
whereby the tensioning strap 10 is guided onto deflection and
winding rollers 14 that are disposed laterally on the roll bar and
to which the inner end of the tensioning straps is firmly
connected, so that when the roll bar 1 is rotated in the direction
of extension, tension is exerted by the tensions strap 10 onto the
sliders 8 and thus onto the drop-out rail 7 and, hence, onto the
awning cloth 5.
[0018] The elastic tensioning straps 10 are installed pretensioned
so that a tensile stress is exerted onto the awning cloth 5 at all
times and the same is held accordingly taut.
