Abstract

The invention relates to an awning system (3) comprising a winding shaft (15), to which an awning web (5) is fixed. The front edge of the awning web (5) is connected to a front bar (6), which is hinged to a lever assembly (7, 8) on a carriage arrangement (9). The carriage arrangement can be displaced longitudinally by the guide bars (11, 12). The front edge of the awning web can then be further extended beyond the end position of the carriage arrangement in the displacement direction. This permits, among other things, an overhang to be achieved.

Description

Awning system with movable drop rail

The area to be shaded with Gelenkarmmarkiseπ is limited by the maximum length of the extended articulated arms. If larger areas are to be shaded, so-called counter awnings are used for this purpose. In Gegenzugmarkisen the drop rail is usually performed in guide rails, with additional measures are required to carry away the drop rail Beitn extending the awning of the winding shaft. The weight of the guide rail is usually not enough on its own.

In order to move away the drop rail from the guide rail, traction means are used, which extend along the guide rail and Einendes are connected to the drop rail.

BESTATIGUNGSKOPIE The other end of the traction device is wound on a winding disc which is coupled to the winding shaft. When extending the awning, the bale diameter of the awning fabric on the winding shaft is smaller, while at the same time increases the winding, which forms the traction means on the winding disk. These opposing movements have tensions that need to be balanced by elastic means. It is known from EP 0 082 302 A1, for example, to provide a torsionally flexible coupling between the winding disk and the winding shaft.

Another equally known solution is to form the drop rail as a tube. Inside the door rail is a spring motor, which endeavors to wind up the awning cloth on the tubular drop rail. For length compensation, a more or less large amount of awning fabric is unwound from the drop rail.

A disadvantage of this arrangement is a clearly recognizable strip-shaped color change, since the wound-up part fades or dirty differently than the extended part.

From DE 197 17 654 a Gegenzuganlage is known in which the drop rail is connected via arms with the guide carriage. In this way, it is achieved that the drop rail protrudes beyond the end of the guide rails remote from the cradle shaft when the awning rail is extended.

It is disadvantageous that when retracting the awning of the carriage on which the drop rail is guided and the winding shaft must submerge. Otherwise, in the retracted state, the drop rail from the winding shaft always have a distance equal to the length of the arms protrude from the guide shafts.

Proceeding from this, it is an object of the invention to provide an awning system in which the remote from the winding shaft end of the awning can have a variable distance from the guide carriage.

This object is achieved with the awning system with the features of claim 1.

In the new awning system two guide rails are provided, by means of which a carriage assembly is guided. On the carriage assembly, a lever assembly is hinged, which connects the carriage assembly with the front edge of the awning. In this way it is possible, for example in the extended end position of the carriage arrangement, to move the respective end of the awning track beyond this end position in order to achieve a canopy effect with the awning track. Although the guide rails already end a bit before, the awning can be moved with its leading edge beyond this point.

On the other hand, allows the lever assembly that the carriage assembly is stopped immediately adjacent to the winding shaft and the distal end of the awning is brought to the winding shaft. It is not necessary to pass the carriage attachment tangentially under or over the winding shaft in order to be able to completely wind up the Markisehbahn.

In addition, the lever assembly allows the same time To replace lengthwise / as otherwise required in Gegenmarmarisen.

In order to move the carriage arrangement into the distal position, i.e., away from the winding shaft, the drive device can assume different shapes. In the simplest case engages the slide assembly at least a linear traction means in the form of a rope or a band, which runs from the carriage assembly to the distal end of the guide rail and from there back to the winding shaft. In the winding shaft, the traction means is wound on a Zugbandscheibe. This Zugbandscheibe is rotatably rigidly coupled to the winding shaft.

Another possibility of the drive device for the carriage assembly is the use of screw or gas springs, which are connected via a kind of pulley with the carriage assembly. ^•

The third possibility to realize the drive means consists of one or more articulated arms, which are angeamiert at one end at the winding shaft and the other ends are connected to the carriage assembly.

In terms of simplicity, the Gelenkarmkonstruktion is very easy to control, while the arrangement with traction cables and WiekelScheiben with very delicate guide rails does not require visually disturbing. The flapper arrangement represents an intermediate between the two solutions in terms of aesthetic design.

The lever assembly that serves to cantilever Achieving the position of the awning cloth, in turn, may in turn comprise articulated arms, one arm of which is mounted on the carriage assembly and the other on the front edge of the awning track. Instead of articulated arms, simple pivoting arms are also suitable, especially if only a small projection is desired. The pivot arms are angear- one end of the carriage assembly and run the other end in a corresponding guide groove of the drop rail.

Moreover, further developments of the invention are the subject of dependent claims.

When studying the description of the figures, it is clear that a number of modifications are possible, which are at the discretion of the person skilled in the art and which follow from the local conditions. In addition, combinations are possible, which are also not explained in order to limit the scope of the description of the figures.

In the drawings, embodiments of the subject matter of the invention are shown. Show it:

Fig. 5 is a schematic representation of an awning system according to the invention with a Flaschenzugan- order as a drive device for the carriage assembly.

Fig. 1 illustrates schematically a building facade 1, which is a glass porch 2 vorgebaute. For Abschan the glass veranda 2 an awning system 3 is arranged above this. To the awning system 3 includes an awning box 4, which is attached to the house facade 1. From the awning box 4, an awning 5 runs out, the front edge is attached to a drop rail 6. As can be seen from the broken-away part of the awning track 5, the drop rail 6 is connected to a slide arrangement 9 via a first pair of articulated arms 7 and, indicated by dashed lines, by a second articulated arm pair 8. The carriage assembly runs in two guide rails 11, of which only one can be seen because of the illustration. The other guide rail can be seen in the schematic representation of FIG. 2 and there bears the reference numeral 12th

The two guide rails 11 and 12 extend above the glass roof of the glass veranda 2, starting at the house facade 1, to the front of the glass veranda. 2 As can be seen Fig. 1, stands in the extended state, the slide assembly 9 on the front of the house facade 1 front of the glass veranda 2, while the drop rail 6, supported by the two articulated arms 7 and 8, of the glass veranda 2 protrudes and there a kind of solar canopy forms. In addition, the awning 5 is wider than it corresponds to the glass veranda 2, so that also creates a kind of canopy to the side.

Thus, the awning system 3 differs from the classic counter awnings, in which the drop rail 6 would remain approximately flush with the front of the glass veranda 2. A shading of the windows on the front of the glass veranda 2 would not be possible with a classic counter-system.

2 shows a plan view, highly schematic, of the essential parts of the awning system 3 according to the invention. The two guide rails 11 and 12 extending parallel to one another at a distance from one another, extending from the house facade 1, not shown in FIG the edge of the glass facade 2 extending from the house facade 1 extend. They thus have an end 13 which is adjacent to the house facade 1, as well as an end 14 which rests from the house facade 1. At right angles to the two guide rails 11 and 12 extends a winding shaft 15 which is rotatably mounted in the awning box 4. The bearing is done with schematically indicated axle journals 16 and 17. The journal 17 simultaneously forms a shaft for rotationally fixed coupling of the winding shaft 15 with a drive motor 18, which is also housed in the awning box 4. On the shaft 17 and on the journal IS sit torsionally two Zugbandscheiben 19 and 21st To the carriage assembly 9 includes two carriages 22 and 23, which are guided in a known manner in the respectively associated guide rail 11, 12. The guide rail consists for this purpose, for example, of a C-shaped profile and can be in this way guide grooves arise in which the two carriages 22 and 23 are guided by rotatable wheels or rollers. Further, the carriage assembly 9 includes a rod 24 which is rigidly connected to the two carriages 22 and 23 and which extends in the position of use above the guide rail 11, 12. The rod 24 has a length corresponding to the width of the awning 5. It serves to support the awning 5, as shown in FIG. 1, at the end of the glass veranda 2.

The carriage 22 forms the point of articulation for the articulated arm 7, which is composed of two arms 25 and 26. The two arms 25 and 26 are connected to each other at a hinge joint 27. A further hinge 28 connects the arm 26 with the drop rail 6. All hinges 27, 28 are parallel to each other and approximately perpendicular to the stretched awning 5. They are also parallel to a hinge axis 29, via which the arm 25 is connected to the carriage 22 ,

The articulated arm 7 is biased in the known manner by means of a coil spring 30 and a pull cable 31 in the extended position. For this purpose, the coil spring 30 is located inside the tubular arm 26 and is anchored there. Its other end is connected to the cable 31, which leads around a deflection at the hinge 27 in the arm 25 and is also anchored there. The articulated arm 8 has basically the same structure, but is arranged in mirror image, ie the two knee joints 27 of the articulated arms 7 and 8 buckle towards each other.

Since the articulated arm 8 is designed in the same way as the articulated arm 7, an explanation is unnecessary insofar. Suffice it to say that the articulated arm 8 at one end, i. with its the house facade 1 facing end on which carriage 23 is hinged and with its distal end also on the drop rail 6. The Ank- kung there is analogously designated by the reference numeral 28 ', while the articulation point on the carriage 23 by the reference numeral 29th 'is provided.

As can be easily recognized, the deflection of the drop rail 6 of an articulated arm awning is similar with the only difference that the otherwise fixed wall bracket of the articulated arm awning are replaced by the two carriages 22 and 23.

In order to move the carriage assembly 9 along the guide rails 11, 12, two traction cables 33 and 34 are provided. The traction cable 33 is attached at one end to the Zugbandscheibe 21 and leads to two guide rollers 35 and 36 to the guide rail 12. The guide roller 36 is located adjacent to the end 13 of the guide rail 12. From here, the traction cable 33 runs to a guide roller 37, the at the distal end 14 of the guide rail 12 is mounted stationary.

The other end of the traction cable 33 is connected to the slide arrangement 9. Merely for reasons of better overview and presentation of the functional relationships, the pull cable 33 is drawn as if it were to run alongside the guide rail 12. In fact, in practice, it will run in a corresponding chamber of the guide rail 12, as is known in the art of return awning.

The pull cable 34 shows a similar course. It extends between the drawstring 19 and the carriage assembly 9 on the side of the carriage 22. The pull cable 34 leads around two fixed deflection rollers 39 and 41 around, from there approximately parallel to the guide rail 11, to a deflection roller 42 and from here to the carriage assembly 9. Again, the thing is shown as if the pull cable 34 would be connected to the rod 24. However, this representation is chosen only for the sake of simplifying the functional relationship. In fact, the traction cable 34, as well as the traction cable 33, anchored to the respective carriage 22 and 23, respectively.

The traction cables 33, 34 and the Zugbandscheiben 19, 21 form the drive means for moving the carriage assembly 9 to the front of the glass veranda.

To explain the mode of operation, it is assumed that the awning track 5 is completely wound up on the winding shaft 15. In this position, the two articulated arms 7 and 8 are folded. The drop rail 6 thus has the smallest distance to the rod 24 of the carriage assembly 9. The carriage assembly 9 and the drop rail 6 are in the immediate vicinity of the winding shaft 15, ie the rod 24 is moved directly to the outlet slot of the awning box 4. In this position, the two traction cables 33 and 34 are unwound maximally from the associated discs 19 and 21.

Since the articulated arms 7 and 8, each biased in itself, the awning 5 and the two traction cables 33 and 34 also remain under the corresponding voltage.

If, starting from this position, the user desires a shading of the glass veranda 2, he switches on the drive motor 18, which sets the winding shaft 15 in the sense of winding the awning track 5 away from the bevel shaft 5. As a result, at the same time the rigid and rotatably coupled to the winding shaft 15 Zugbandscheiben 19 and 21 in the sense of Aufwickeins the associated traction cables 33 and 34 wound on the Zugbandscheiben 19 and 21. This shortens the free length of the two traction cables 33 and 34, which endeavor to move the carriage assembly 9 in the direction of the distal end 14 of the two guide rails 11, 12. By appropriate dimensioning of the diameter of the winding shaft 15 in conjunction with the formed on the winding shaft 15 bales of awning fabric 5 and the diameter of Zugbandscheiben 19 and 21 ensures that each revolution of the winding shaft 15 and the rigidly coupled Zugbandscheiben 19 and 21 a larger Length is unwound at awning webs 5 is wound as a length to pull cable 33 and 34 on the drawstring 19 and 21 respectively. This difference in length would in itself lead to the fact that, in the course of the movement, the awning track 5 would start sagging slackly because the slide arrangement 9 moves more slowly than the front free edge of the awning track 5 could move. Because the free edge or front edge of the awning track 5, however, is connected via the blind rail 6 to the two articulated arms 7 and 8, this length difference is compensated by a gradual stretching of the two articulated arms 7 and 8.

The larger stroke, the awning 5 performs the extension when compared with the stroke of the two traction cables 33 and 34, is collected by the stretching of the two articulated arms 7 and 8. At the end of the extension movement, the carriage arrangement 9 is in abutments on the distal end 14 of the two guide rails 11, 12 and the articulated arms 7, 8 are maximally stretched. The drop rail 6, which is connected via the extended articulated arms 7 and 8 to the carriage assembly 9, is thus carried in a respect to the carriage assembly 9 off or projecting position in front of the front of the glass veranda 2.

The tension in the awning track corresponds to the pretension that can be generated by the two articulated arms 7 and 8.

To retract the drive motor is set in the opposite direction of rotation in motion. As a result, the winding shaft 15 rewinds the awning track, while the two tensioning cables 33 and 34 are unwound from the tensioning pulleys 19 and 21. Since the awning travels faster than traction cable is provided, the retraction leads to folding the articulated arms 7 and 8 against the action of the bias generated from the inside.

The use of articulated arms for producing the canopy in the extended position of the awning system according to the invention is preferred when a wide Auskra- is desired. The essential difference from the arrangement according to FIG. 2 is the use of simple levers 45 and 46, which at one end, like the articulated arms 7 and 8, on the carriages 22 and 23 at 29 or 29 'hinged. The other end of the levers 45 and 46 is slidably guided in a guide groove 27 of the drop rail 6. By biasing springs 48 and 49, the two levers 45 and 46 are biased in a position in which they are pivoted away from the rod 24 and the carriage assembly 9. The springs 48 and 49 are shown here as compression springs, but they can also be realized by ropes are guided around the hinges 29, 29 'as in articulated arms, to produce the bias.

When retracting and extending, the levers 45 and 46 pivot about the hinges 29, 29 'and thus change the distance that the drop rail 6 from the carriage assembly 9 has. The principal effect is the same as explained in connection with FIG. 2.

Fig. 4 shows an arrangement in which the drive means for moving the carriage assembly 9 along the guide rails 11 and 12 by means of a second Gelenkarmpaar 50 and 51 is accomplished instead of the traction cables 33, 34 and the Zugbandscheiben.

The two articulated arms 50 and 51 have in principle the same structure, as described in detail in connection with the articulated arm 7. Only their arms 52, 53 and 54, 55 have a length adapted to the intended use. The articulated arm 50 is mounted in the vicinity of the winding shaft 15 via a hinge 46 stationary. The other end of the articulated arm 50 is hingedly connected to the carriage 22.

The articulated arm 21 is likewise hinged in a fixed manner via a hinge joint 57 in the vicinity of the winding shaft 15, while the other end is hingedly connected to the carriage 23.

Otherwise, the construction of the awning system 3 corresponds to the arrangement according to FIG. 1.

By selecting the bias of the articulated arms 7, 8, 50, 51, it can be ensured during unwinding of the awning web 5 of the winding shaft that initially extend the two articulated arms 50 and 51 and thereby bring the carriage assembly 9 to the front edge of the glass veranda 2. Only when this position is reached and the slide assembly 9A arrives at stops of the guide rails 11, 12, in a further unwinding of the awning 5, the articulated arms 7 and 8 begin to stretch to produce the desired solar canopy.

As can be seen from the above descriptions, there are a number of ways to bring the carriage assembly 9 when extending the awning to the far away from the house facade 1 end of the glass veranda. Only for completeness, a further variant is shown in Fig. 5. It come here as a drive means for the carriage assembly 9 bottle trains 60 and 61 are used.

The pull cable 33 is next to the winding shaft 15 at 59 anchored in place. It leads from here to a deflection roller 62 and from there to a deflection roller 63 to the aforementioned deflection roller 37 adjacent to the distal end 14 of the guide rail 12th

The traction cable 33 is connected to the carriage assembly 9 according to the embodiment of FIG. Since the traction cable 33 runs in the opposite direction between the two deflection rollers 62 and 63, the effective length between the ends of the traction cable 33 is shortened when the rollers 62 and 63 are removed from each other. To accomplish this, the two rollers 62 and 63 are biased away from each other by a gas spring 64. This creates a constant force that tends to shorten the effective length of the pull cable 33 and thus move the slide assembly 9 toward the distal end 14 of the guide rail 12.

The illustration is schematized. The position devices and guide devices for the parts of the bottle assembly 60 are not shown.

The design of the guide rail 11 is similar / here it extends the pull cable 34 from the attachment point 58 on the pulley 61 to the carriage assembly 9.

Incidentally, the function is the same, as already explained in detail in connection with the preceding figures.

An awning system has a winding shaft to which an awning is attached. The leading edge of the mar- senbahn is connected to a drop rail _/ which is connected via a lever arrangement on a carriage assembly. The carriage arrangement can be moved longitudinally along guide rails, With the aid of the lever arrangement it is possible to extend the leading edge of the awning track further beyond the end position of the carriage arrangement in the direction of movement.
