motor (19), and a rope sheave (21) is connected to the drive shaft
(23).
4. An awning according to claim 3, wherein the rope sheave (21) is
disposed in the region of one end (12) of the drive shaft (2).
5. An awning according to claim 4, wherein the rope sheave (21) is
formed as one piece with a bearing tube (22), with the roller tube
(2) supported by means of bearing rings (14, 15) sitting on the
bearing tube (22).
Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention is directed to an awning comprising a
roller tube for winding up an awning fabric, wherein the roller
tube is actuated in the winding direction by a torsion spring.
Awnings of this type are also referred to as roller blinds. They
are generally extended manually and wind themselves up
automatically driven by the spring.
SUMMARY OF THE INVENTION
[0003] With this as the starting-point, the invention has as its
object to design an awning of this type in such a way that it can
be driven alternatively also by means of an electric motor, and a
compact, largely factory-pre-assembled construction is attained
that permits a quick installation at the window and can be used
also for more complex shade systems, such as, e.g., triangular
awnings.
[0004] This object is met according to the invention in such a way
that the roller tube is disposed inside a housing and supported on
its one end in a first face-end cover of the housing, with the
torsion spring disposed in the interior of this first end of the
roller tube and the roller tube supported in the region of its
opposite second end by means of a bearing journal that extends away
from a face-end cover. In particular, provision is made for the
bearing journal to be detachably screwed to the inside of the
face-end cover.
[0005] This arrangement as such is an advantageous improvement of a
mechanical roller spring that is known per se.
[0006] In a further improvement of the invention, provision is
furthermore made for the bearing journal to be formed by the driven
shaft or its extension of an electric motor, with a rope sheave
connected to the driven shaft.
[0007] This improvement permits, on one hand, to implement both a
manual and a motor drive using the same basic construction; in
particular, however, a tension rope can be driven via the rope
sheave that acts on the free outer end of the awning fabric via
deflection rollers and accordingly attains an even pulling and
defined extension movement for the awning fabric even in
complicated shade systems.
[0008] The rope sheave is advantageously disposed in the region of
one end of the roller tube and formed as one piece with a bearing
tube, with the roller tube being supported via bearing rings that
sit on the bearing tube.
[0009] The invention will be explained in more detail below, based
on a preferred exemplary embodiment in conjunction with the
drawing.
BRIEF DESCRIPTION OF THE DRAWING
[0010] FIG. 1 shows a longitudinal section through an inventive
awning without motor drive,
[0011] FIG. 2 shows an illustration corresponding to FIG. 1 with a
motor, and
[0012] FIG. 3 shows a section along the line III-III in FIG. 2.
DESCRIPTION OF THE PREFERRED EMBODIMENT
[0013] In FIG. 1 an awning is shown that comprises a housing 1 in
which a roller tube 2 is disposed for winding up an awning fabric
not shown in the drawing.
[0014] In the interior of the roller tube 2, on one end 3, which is
shown as the left end in the drawing, a torsion spring 4 is
disposed, one end 5 of which is fixed on a shaft 6 on which the
torsion spring 4 sits, and the shaft 6 penetrates through a bearing
ring 7 and a driving bearing ring 8, with the spring 4 acting on
the roller tube 2 via the driving bearing ring 8 and a spring
projection 9 in such a way that it actuates the extended awning
fabric in the retraction direction. The outer end 10 of the shaft 6
is supported in a face-end cover 11.
[0015] On the opposite end 12 of the roller tube 2, a bearing
journal 13 is provided on which the roller tube 2 is supported via
two spaced-apart bearing rings 14, 15 with the bearing ring 15
sitting against a radially projecting ring flange 16 of the
bearingjournal 13. The bearingjournal 13, in turn, is fastened on a
face-end cover 17 by means of a screw 18.
[0016] In this design, the awning can be operated manually in the
usual manner, i.e., the awning fabric is extended against the force
of the torsion spring 4 and locked, and retracted and wound up
under actuation by the torsion spring 4.
[0017] FIG. 2 shows a design according to FIG. 1, in which the
bearing journal 13 is now replaced by a motor 19 that has an
electrical connection 20. A rope sheave 21 is connected to a
bearing tube 22, which is supported between the bearing rings 14,
15. The roller tube 2, which, of course, sits on the bearing rings
14, 15, on the outside, is accordingly also supported on this
bearing tube 22. The bearing tube 22, in turn, sits on the drive
shaft 23 of the motor 19.
[0018] A rope or the like, the outer end of which is connected to a
front rail fastened on the outer edge of the awning cloth, may be
wound up onto the rope sheave 21 so that, in combination with a
suitable deflection arrangement for the rope, the unwinding
movement of the roller tube 2 during the extension of the awning
fabric is accompanied by a tension exerted onto the outer end of
the awning fabric by the rope which is wound onto the rope sheave
21.
