2 1 The invention relates to an articulated arm awning comprising two holding brackets to support the fabric shaft and a drive/motor and side faces disposed on the holding brackets, with each side face having a bearing for in each case one articulated arm, and with each side face being provided with a projection passing through a recess of the associated holding device. An articulated arm awning of this type is known from EP B1. Generally, it has proven to work exceptionally well in practical application On this basis, the object of the invention is to further develop a known articulated arm awning of this type in such a way as to achieve a construction that is as flat as possible in the retracted state and to facilitate the design thereof while ensuring a smooth movement when being retracted to the final position. According to the invention, this object is achieved by the features in the characterising part of claim 1 according to which, in order to ensure an automatic pivoting movement, a bearing for the drive or the drive motor, is directly connected, in particular screwed, to the holding device, a stop being provided for limiting a pivoting movement of the articulated arms in an upward direction. Furthermore, a cover is provided that covers the recess in the holding device, in particular the wall bracket, the cover being directly connected, in particular screwed, to the projection of the side face. 2 Consequently, a novel tilting mechanism is implemented according to the invention in such a way that articulated arms and drop-out profile are able to pivot downwards up to an adjustable angle according to the laws of gravity.

3 - 2 - This design is simpler than the previously known solution and results in a smooth, low-noise movement during retracting. The holding device, in particular the wall bracket, may preferably be provided with a threaded hole comprising a set screw the inner end of which abuts against a protruding nose of the projection to adjust the slope of the side face, strictly speaking the associated articulated arm. Furthermore, a device is advantageously provided for switching off the drive motor as soon as the retracted final position is reached. This device can advantageously be formed by a torque limiting device that is activated as soon as a stop is reached According to another preferred embodiment of the invention, the articulated arm awning may be equipped with a windlock device preventing the awning from abruptly turning up, for instance in stormy weather, when the awning is extended. When retracting the awning, said windlock device is being deactivated. The invention will hereinafter be explained in more detail by means of a preferred embodiment of the invention, taken in conjunction with the drawing, in which 2 Fig. 1 shows the region of a prior art holding device according to EP B1, Fig. 2 shows an exploded view of said region in an embodiment according to the invention, and

4 - 3 - Fig. 3 shows a top view of the region according to Fig. 2. Fig. 1 shows a holding device (wall bracket 1 ) to be inserted into a horizontal wall holder 2. The holding device (wall bracket 1 ) has a bearing recess 3 and three elongated holes 4. A side face is provided externally of the holding device (wall bracket 1 ), i.e. related to Fig. 1 on the left side of the holding device (wall bracket 1 ), the side face having, in the region of its front end as shown in the drawing, a bearing 6 comprising an upper bearing lug 7 and a lower bearing lug 8 with bearing holes, 11 for a bearing journal of an inner articulated arm portion of the articulated arm awning. 1 Furthermore, the side face is provided with a projection 12 having a step, in other words a nose In the mounted state, the projection 12 passes through the bearing recess 3 of the holding device (wall bracket 1 ). The recess 3 is engaged from below by a set screw 14 that abuts against the nose 13 so as to allow the slope of the side faces and the articulated arms mounted thereto to be adjusted, in other words the further the set screw 14 is being screwed down, the greater the resulting change in slope of the articulated arms in the horizontal direction. 2 In the holding device (wall bracket 1 ), a bearing cover 1 is provided for mounting the motor or gearbox 16 by means of a star-shaped bearing recess 17. The bearing cover 1 is screwed to the projection 12 of the side faces by means of fastening screws 18, with the fastening screws 18 passing through the elongated holes 4 of the holding device (wall bracket

5 - 4-1 ). Therefore, a pivoting movement of the side face and the bearing cover 1 connected thereto in a non-rotational manner is possible. The solution according to the invention shown in Fig. 2 also comprises a holding device (wall bracket 1) to be mounted to a horizontal ceiling holder not shown in the drawing, with the holding device (wall bracket 1) for this purpose being provide with a hook-shaped projection 19 and a projection 20 with fastening recesses 21. Outside the holding device (wall bracket 1), a side face is provided, the side face comprising a bearing 6 for an articulated arm, with the bearing 6 comprising an upper bearing lug 7 and a lower bearing lug 8. 1 The inner side of the side face is provided with a projection 12 having a step or nose 13, with the projection 12, in the mounted state, passing through a bearing recess 3 of the holding device (wall bracket 1). 20 In the holding device (wall bracket 1), a set screw 14 is provided, the set screw 14 abutting against the nose 13 of the projection 12 so as to allow the slope of the side face, strictly speaking the articulated arms 22 mounted thereto, to be adjusted. Said articulated arms 22 in turn have a bearing 23 that engages the bearing 6 of the side faces. 2 The projection 12 on the side face has three threaded holes 2a. When mounted, said threaded holes 2a allow a cover 24 having three corresponding fastening holes 2 to be screwed on by means of fastening screws (not shown). The cover 24 has a greater diameter than the bearing recess 3 of the holding device (wall bracket 1) so in this manner, the articulated arm 22 is pivotably mounted to the holding device (wall bracket 1) via the side

6 -- face, the downward pivoting range being limited by the set screw 14 or the nose 13. A bearing 26 in the form of a motor bearing cover is provided with fastening holes 27 and is greater in diameter than the cover 24, the bearing 26 thus being able to encompass the cover 24 by means of a bulge or step 28. By means of fastening screws not shown in the drawing, the cover-shaped bearing 26 is directly screwed to threaded holes 29a of the holding device (wall bracket 1). A star-shaped bearing recess 17 allows the motor and the gearbox fastened thereto in a non-rotational manner to be mounted When the articulated arm awning is being retracted, the drive motor, which is mounted non-rotationally and stationarily, drives the fabric shaft 33 to wind up the awning fabric 34, causing a drop-out profile disposed on the outer end of the articulated arms 22 in a manner known per se to be retracted. In the extended state, the articulated arms 22 have a slope that is adjustable by means of the set screw 14 as mentioned above. When the drop-out profile has reached the region of the inner final position with the articulated arms 22 being retracted, in other words the inner articulated arm portions are virtually parallel to the fabric shaft 33, an upwardly directed torque is applied, in the direction of the arrow P, to the articulated arms 22 and therefore the side faces connected thereto due to the tensile force exerted by the awning fabric 34 and the drop-out profile, causing side faces and articulated arms 22 to be pivoted upwards into a horizontal position. Once said horizontal position is reached, the drive motor is switched off. In the exemplary embodiment, this is done by a torque limiting device at the very moment the upper side of an upper bearing lug 7 of the bearing 6 of the respective articulated arm 22 reaches and abuts against the lower side

7 of the hook-shaped projection 19 of the holding device (wall bracket 1), causing the torque applied to the drive motor to increase. 1 As can in particular be seen from Fig. 3, the awning is equipped with a windlock device formed on the one hand by a stationary safety stop 3 on a setting ring 36 and by a knob-like stop protrusion 30 on the other, the stop protrusion 30 protruding radially from the bearing 23 of the articulated arms. The setting ring 36 is fixable to the step 28 of the bearing in the form of the motor bearing cover 26 in flexible rotational positions, thus allowing the locking angle of the windlock device to be adjusted. As can be seen from Fig. 3, in the extended position of the articulated arm 22, the stop protrusion 30 engages the safety stop 3 on the setting ring 36 from below in such a way that an upward pivoting movement of the side face, for instance in stormy weather, is prevented. In the retracted state of the articulated arms 22, as shown by dashed lines in Fig. 3, the stop protrusion 30 disengages from the safety stop 3, thus enabling the pivoting movement to take place once the retracting movement as described above is completed.
