Abstract
In an articulated-arm awning comprising two brackets for supporting the winding shaft and articulated arms, as well as a device for adjusting the slope of the articulated arms, also side faces disposed on both sides of the winding shaft, provision is made for the side faces to be fixed on the outside of the brackets, and for each articulated arm to be connected in an articulated fashion to the inside of one side face, and for the winding shaft to be supported on the brackets.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The invention is directed to an articulated-arm awning comprising two holding brackets to support the winding shaft and articulated arms, as well as a device for adjusting the slope of the articulated arms, also side faces disposed on both sides of the winding shaft.




2. Background Art




Most articulated-arm awnings incorporate a so-called installation tube that extends parallel to the winding shaft at a distance from the same and to which the articulated arms and the device for adjusting the slope of the articulated arms are fixed.




On the other hand, designs without an installation tube are also known, wherein the articulated arms must be supported by different means.




SUMMARY OF THE INVENTION




The invention is based on the object of improving an articulated-arm awning of the above type in such a way that a compact and stable construction is attained along with a simple adjustability of the slope of the articulated arms.




This object is met according to the invention in such a way that the side faces are fixed to the outside of the brackets, each articulated arm is connected in an articulated fashion to the inside of one side face, and the winding shaft is supported on the brackets.




The side faces accordingly, on one hand, assume the conventional function of a side cover, which acts both as protection and also represents a decorative element. On the other hand, at the same time, it serves for mounting the articulated arms.




A further embodiment of the invention provides for the side faces to incorporate a support extension that is pivotably supported in a support cutout of the brackets in such a way that its final position is adjustable. A compact support means and adjustability of the angle are thus implemented at the same time.




To this extent, provision may be made in particular for the support extension to have a support section in the shape of a segment of a circle, and a recessed cam section that has a smaller curvature radius and a shoulder.




To adjust the slope, provision is made for the wall holder to furthermore comprise a threaded bore for at least one set screw, which is oriented such that the set screw sets under the above-mentioned shoulder of the cam section from below and locks the same in place in dependence upon its axial position.




To prevent a lifting by gusty winds, provision may be made for a second threaded bore to be provided approximately parallel to the first set screw for a second set screw that acts radially further inward on the cam section.




Provision may furthermore be made for the center longitudinal axis of the winding shaft to be flush with the center of the pivot support for adjusting the slope. This ensures that the position of the winding shaft remains unchanged regardless of the set slope.




The invention will be explained in more detail below based on a preferred embodiment in conjunction with the drawing.











BRIEF DESCRIPTION OF THE DRAWING





FIG. 1

shows a top view of an exterior region of an inventive articulated-arm awning,





FIG. 2

shows a section along line II—II in

FIG. 1

, and





FIG. 3

shows an illustration corresponding to

FIG. 2

with a changed slope setting of the articulated arms, and





FIG. 4

shows an exploded view of the support region.











DESCRIPTION OF THE PREFERRED EMBODIMENT




An articulated-arm awning


1


shown in the drawing comprises two wall holders


2


, two brackets


3


placed thereupon in a form-fitting connection, and a winding shaft


4


that serves to wind up the awning cloth and is supported in manner so that it can rotate around the shaft axis


5


.




Disposed on the outside of the brackets


3


are side faces


6


, on the inside of which two articulated arms


10


comprising two articulated-arm sections


8


,


9


are fastened via a fastening extension


7


. The inner articulated arm section


8


is connected to the fastening extension


7


via a pivot hinge


11


and on the other hand to the outer articulated arm section


9


via a pivot hinge


12


, and the outer articulated arm section


9


, in turn, is again connected via a pivot hinge


13


to the drop-out profile


14


. The awning cloth, which is not shown per se, is fixed to the latter via edge profile grooves


14


′.




The side faces


6


have on their inside a support extension


15


that is pivotably supported in a corresponding round support cutout


16


of the holding brackets


3


. The pivot center


5


′ of this support extension


15


is flush with the longitudinal axis


5


of the winding shaft.




The support extension


15


comprises a section


17


in the shape of a segment of a circle, and a cam section


18


, with the cam section in turn comprising a curved section


19


with a smaller curvature radius than the circular segment-shaped support cutout


16


, and a shoulder


20


that is formed in this manner.




The bracket


3


is provided with two parallel threaded bores


21


,


22


extending at a distance from one another for set screws


23


,


24


, with the first set screw


23


ending in the region of the support extension


15


in such a way that it comes to rest below the shoulder


20


so that it supports the shoulder


20


from below and an axial shifting of this set screw


23


that serves to adjust the slope changes the angle position of the support extension


15


and thus also the angle position of the connected side face


6


and accordingly, in turn, also the angle position of the articulated arms


10


that are fixed to the side face


6


. The second set screw


24


prevents the support extension


15


from being twisted in an upward direction, so that protection is also attained in this manner against a lifting by gusty winds, etc.




The comparison of

FIGS. 2 and 3

clearly shows how changing the position of the set screw


23


and the set screw


24


, respectively, permits the position of the articulated arms


10


and accordingly also of the drop-out profile


14


to be changed from a horizontal position, i.e., one with a slope of 0° shown in

FIG. 2

, to a position sloped by 30° shown in FIG.


3


.




The side faces are fixed on the bracket


3


by means of a support cap


25


with borings


26


for fastening screws


27


that extend through long holes


28


of the bracket


3


and engage into threaded bores


29


on the inside of the side face


6


. The support cap


25


serves to support the winding shaft


4


.
