Description

Extendable shading device

The present invention relates to an extendable shading device with a donor.

Awnings, for example, are known as extendable shading devices, in which the awning fabric, when the awning is extended, runs obliquely downward from its suspension, for example on a house or balcony wall. There is a similar situation with seats in front of houses, which are also protected against the sun's rays with sloping canopies that are firmly anchored to one of the walls of a house. During the day, the sun changes position, being low above the horizon in the morning and evening. During these times, the type of canopy mentioned provides little shade. But around noon, too, the sun's rays penetrate under the canopy, especially in the area of the canopy that adjoins the wall of the house. You can find practically the same situation with awnings.

If you want to protect yourself from the sun's side radiation, you can place a wall in the area of the sloping canopy side edge, for example a so-called Spanish wall, the upper edge of which, however, is usually below the lowest point of the canopy. This upper edge of the side wall and the canopy side edge delimits an opening between the side wall and the canopy, which has an essentially trapezoidal outline. Through this opening, sun rays can also get rainwater under the canopy. In principle, you could throw a piece of fabric over the canopy side edge so that the opening is covered with the trapezoidal outline. Because of its own weight, due to gusts of wind, etc., the fabric would hardly stick to the front edge of the roof for a long time, if at all Apply fabric to the edge of the canopy.

The object of the present invention, this disadvantage and further Nachfeile ⁿ of the prior art to be eliminated.

This object is achieved according to the invention when the type mentioned at the beginning is set up, as defined in the characterizing part of patent claim 1.

Embodiments of the present device are explained in more detail below with reference to the accompanying drawings. 1 shows a side view of a house with a covered forecourt, where a first embodiment of the present device can be located, FIG. 2 shows a guide device for the device according to FIG. 1 in a side view,

Fig. 9 enlarges a section of Fig. 8 and

10 shows a side view of a further development of the fourth embodiment of the present device from FIG. 8. In Fig. 1, a house 1 with a forecourt 2 is shown schematically in a side view. The forecourt 2 has a sloping roof 3, the top, first horizontal edge 4 of which is anchored to one of the side walls 5 of the house 1 = the area of the opposite, second horizontal edge 6 of the canopy 3 is lower than the first horizontal edge 4 thereof and the latter lower edge region 6 is supported by posts 7 in the case shown. The canopy 3, the side wall 5 of the house 1 and the relevant post 7 delimit a lateral opening 8 of the forecourt 2, through which sun rays and rain etc. can penetrate into the interior of the forecourt 2.

The present shading device 10 is arranged in the upper region of the lateral opening 8 of the forecourt 2. This shading device 10 comprises a practically vertical, areal and shadow-giving section 11. In the case shown in FIG. 1, the shade dispenser 11 is made of a textile fabric 23. The lower edge 26 of this piece of fabric 23 is located at a greater distance from the floor 27 of the forecourt 2. If desired, the piece of fabric 23 can also be made so long that the lower edge 26 of the same is practically on the floor 27 of the forecourt 2. As such, the piece of textile fabric 23 is not dimensionally stable. Therefore, the upper edge 24 of such a piece of fabric 23 must be held and guided. For this purpose, the present device 10 has a guide device 12. The upper edge 24 of the piece of fabric 23 is connected to the upper edge of this guide device 12.

The guide device 12 is designed essentially like a scissor pull-out (FIG. 2), the main plane of which extends vertically. The guiding device 12 is associated with the Schattensp ^'ender or diaphragm 11 in the illustrated case the outer side. However, it is also possible for the guide device 12 to be assigned to the inside of the shade or cover 11. This guide device 12 is below at least one of the lateral edges of the Canopies 3 arranged and it is attached at one end to a vertical support. One of the walls 5 of the house 1 serves as such a support in the present case.

The scissor pull-out 12 has crossing members 13, 14, 15, 16, 17 and 18. These scissor members 13 to 18 can be made of metal, wood or plastic. Those scissor links which have an odd number at the end of their reference number can also be mentioned as the first scissor links. Those scissor links that have an even number at the end of their reference points can also be called second scissor links. In the area in which two of the links mentioned cross (FIG. 3) there is an axis 19 which passes through the intersecting scissor links. The intersecting scissor members can pivot about this axis 19 when moving out and when retracting the scissors extension 12.

The crossing points 19 divide the intersecting scissor links into two sections 131 and 132 or 141 and 142 or 151 and 152 or 161 and 162 or 171 and 172 or 181 and 182. Those link sections which have an odd number at the end have their reference number, can also be mentioned as upper link sections. Those link sections which have an even number at the end of their reference number can also be referred to as lower link sections.

Further axes 20 pass through the overlapping end parts of the successive scissor members 13 to 18 lying above the crossing points 19, so that these end parts together with the axes 20 form joints. The end portions of the scissor links can pivot about these axes 20 during operation of the guide device. Corresponding locations of the upper edge 24 of the piece of fabric 23 are connected to these overhead joints 20 in a manner known per se. Hangs from here the piece of fabric 23 down. Further axes 21 pass through the overlapping end parts of the successive scissor members 13 to 18 lying below the crossing points 19, so that these end parts together with the axes 21 form joints. The end portions of the scissor links located below can pivot about these axes 21.

The end portion of the overhead section 131 of the first scissor link 13 is pivotally articulated on the house wall 5 or the like via a further axis 29. The free end part of the lower section 142 of the second scissor member 14 is slidably mounted on the house wall 5 or the like. For the slidable mounting of this section 142 of the second scissor member 14, a sliding device 30 known per se with a guide rail 28 (FIG. 1) and with a sliding block 22 guided in this rail 28 and only schematically indicated here can be used. The scissors extension 12 is shown in FIGS. 1 to 3 in the extended position. When the scissors extension 12 is pulled back, the free end of the upper scissor link section 131 pivots about the axis 29 on the house 1. The sliding block 22 at the free end of the lower scissor link section 142 slides downward in its guide rail 28. Here, the crossing point 19 of the scissor members 13 to 18 move against the house wall 5 or the sliding device 30.

In the illustrated case, the shading device 10 is extended and retracted with the aid of a cable pulling device 70. The cable pulling device 70 shown has a roller 71 which is attached to the guide rail 28 approximately at the middle height of the shading device 10. The cable pull device 70 further comprises a tension member 72 which is guided over the roller 71. The section 73 of the tension member 72 which hangs from the roller 71 is used to operate this cable pulling device 70. The section 74 of the tension member 72 which extends almost horizontally from the roller 71 is in the case shown to the crossing point 19 of the guide direction 12 connected.

What is special about the present guide device 12 is that it extends obliquely downwards in its extended position with respect to the house wall 5. This is achieved in that the scissor members 13 to 18 of the guide device 12 are of different lengths and / or in that the mentioned intersection points 19 are not in the middle of the length of the respective scissor members 13 to 18. These measures enable the scissor members 13 to 18 to lie flat or parallel to one another when the scissor pull-out 12 is pulled back against the house wall 5, although the scissor pull-out 12 ran obliquely downward in its extended state.

So that the scissor pull-out can run obliquely downward from the house wall 5 towards the left, as shown in FIG. 2, the length of the upper section 131, 151 and 171 of the first scissor members 13, 15 and 17 is greater than that

Length of the lower section 132, 152 and 172 of these scissor members 13, 15 and 17. In the example shown in FIG. 2, the length of the upper section 131, 151 and 171 of the first scissor members 13, 15 and 17 is approximately 1.4 times greater than the length of the lower section 132, 152 and 172 of these scissor members 13, 15 and 17.

With the second scissor members 14, 16 and 18, this is just the other way round. The length of the upper section 141, 161 and 181 of the second scissor members 14, 16 and 18 is less than the length of the lower section 142, 162 and 182 of the second scissor members 14, 16 and 18. In the example shown in FIG. 2, the length is of the upper section 141, 161 and 181 of the second scissor members 14, 16 and 18 is approximately 1.4 times smaller than the length of the lower section 142, 162 and 182 of the second scissor members 14, 16 and 18.

As far as the length of the scissor links 13 to 18 is concerned, the first ren member 13 longest. The length of the scissor members 14 to 18 following the first scissor member 13 gradually decreases, so that the last scissor member 18 which is the most distant from the house wall is the shortest. The length of the longest first scissor link 13 is about 215 cm in the case shown. The length of the scissor member 15 preceding this longest first scissor member 13 is 153 cm in the case shown. The length of the shortest first scissor link 17 is 108 cm in the case shown. The length of the longest second scissor link 14 is 173 cm in the case shown. The length of the scissor member 16 preceding this longest second scissor member 14 is 122 cm in the case shown. The length of the shortest second scissor link 18 is 87 cm in the case shown.

It goes without saying that the numerical relationships relating to the length of the scissor members 13 to 18 and the length of the sections thereof determine the inclination of the extended guide device 12. The inclination of the guide device 12 in the extended state can be changed as desired by a suitable choice of the numerical ratios mentioned. In this way it can be achieved that the inclination of a straight line G which orrichtung by the overhead joints 20 of the Führungsv ^'is 12 hindurch-, can be adapted to the inclination of the hood 3 so that the straight connecting line G to the underside of the canopy 3 runs parallel. The closer it is possible to bring this connecting line G to the underside of the canopy 3, the narrower the gap 25 between the upper edge 24 of the fabric web 23 and the canopy 3. And the less sun rays, rain water etc. through it Gap 25 can get under the canopy 2. It is most expedient if the guide devices 12 and / or the shadow dispenser 11 are located below one of the lateral edge parts of the canopy 3.

Another embodiment of the present device comprises two guide tion devices 1, the main planes of which are vertical and which are at a horizontal distance from one another. These guide devices 12 are attached at one end to a wall or to posts. The shadow-giving material is a textile material and this piece of fabric extends between the above-mentioned guide devices 12. Corresponding locations of the edge parts of this piece of fabric are connected to the upper joints 20 of the guide devices 12. A shadow dispenser 11 can each hang down from the upper joints 20 of the respective guide device 12 in the manner described above.

FIG. 4 shows a further embodiment of the present device 80. The base body of the shade or the cover 31 of this device 80 has vertical slats 32 and 36. These slats 32 and 36 can be made of plastic, for example. However, the respective slat 32 or 36 can also be designed such that it has a frame (not shown) which has the shape of the outline of the respective slat 32 or 36. This frame is covered with a fabric. This option offers the. Possibility to choose fabrics with pleasing patterns for the production of slats 32 and 36. The longitudinal edges 33 of the adjacent slats 32 and 36 are connected to one another in a manner known per se in a flexible or articulated manner. This connection can be made using hinges 35. That lamella 36, which is located on one of the vertically extending ends of the diaphragm base body, is also connected to a bearing device 9 so that it can be pivoted horizontally, this connection also being able to take place with the aid of hinges 35. This bearing device 9 is attached to a house wall 5 or to a post.

In the extended state of the shadow dispenser 31, the upper edge 34 of the shadow dispenser 31 runs obliquely downward away from the longest slat 36 and, if possible, parallel to the canopy 3, which also runs obliquely downward. Here, the distance between the oblique edge 34 of the shade 31 and the underside of the canopy 3 should be as small as possible so that as little sun rays as possible get under the canopy 3.

A guide device 37 for the shade 31 is also provided. This guide device 37 is designed so that it holds the slats 32 and 36 in their extended position. This guide device 37 can be designed, for example, as a rod 38, which is mounted at the one end in the region of the holding device 9 so as to be vertically pivotable. When the shade 31 is retracted, the rod 38 is pivoted up about a hinge 39 on the holding device 9 parallel to the holding device 9. After the shade 31 has been brought into its extended position, the guide bar 38 then moves from its vertical to its horizontal position (Fig. 4) brought so that it is in contact with the large surfaces of the slats 32 and 36. In this way, the guide rod 38 prevents the shadow dispenser 31 consisting of slats 32 and 36 from moving unintentionally against the holding device 9. It is most expedient if the shadow donor 31 and / or the guide device 37 is located below one of the lateral edge parts of the canopy 3.

FIG. 5 shows a third embodiment of the present shading device 90 in a side view. FIG. 5 mainly shows the upper section of the opening 8 from FIG. 1. FIG. 6 shows a section of a further development of this third embodiment of the present invention in a side view - Direction 90, which corresponds to the representation according to FIG. 5. The guide device 40 of this shading device 90 has rods 41, 42, 43 and 44, which can have different lengths. The first rod 41 of this guide device 40 is not pivotally attached to the wall 5 or the like. The other rods 42 to 44 are pivotally supported at one end in a holding device 45 of the present device 90. This holding In the case shown, device 45 is located in the area of side wall 5 of building 1, where it can also be fastened. The holding device 45 is located in the lower region of this device 90.

The holding device 45 can be designed such that the inner ends 46 of the guide rods 42 to 44 sit next to one another on a common and practically horizontal axis (not shown) and can be pivoted about them.

Better and more permanent guidance of the rods 42 to 44 can be achieved if the holding device 45 comprises at least one cheek 47. This cheek 47 is designed as a plate, which expediently has the shape of a segment of a circle. The central angle of this segment of the circle can be approximately 90 degrees. Such a cheek 47 has two practically rectilinear legs 48 and 49, which close an angle of practically 90 degrees between them. The cheek 47 can be fastened, for example, to the wall 5 of a building 1 via the vertical leg 48. An arch 50 extends between the cheek legs 48 and 49 with a central angle of likewise approximately 90 degrees. It is expedient if the holding device 45 comprises two cheeks 47, one of which is located on one of the sides of the rods 41 to 44. These cheeks 47 are thus assigned to the inner end parts 46 of the guide rods 41 to 44.

Openings 51, 52 and 53 are made in the material of the corner region of the cheek 47 where the straight legs 48 and 49 meet, each of which has a pivot axis in each of these openings 51 to 53. The respective pivot axis 51 to 53 passes through the inner end section 46 of the respective pivotable guide rod 42 to 44, so that these rods 42 to 44 can pivot about the respective axes 51 to 53. In Fig. 5, the present device 90 is shown in its extended position, so that the guide rods 41 to 44 represent a fan-like structure. In contrast, in the retracted state of the device 90, the guide rods 41 to 44 should be arranged next to one another as space-saving as possible (not shown). To achieve this, the openings 51 to 53 in the cheek 47 are arranged at different horizontal distances from the first and vertically running guide rod 41. It is expedient if the position of the openings 51 to 53 and thus also of the pivot shafts is also different in the vertical direction. The horizontal distance between two adjacent openings 51 to 53 corresponds to the diameter of one of the rods 42 to 44 if the guide rods 42 to 44 have the same diameter. This enables problem-free extension and retraction of the guide rods 42 to 44. In such a case, all the guide rods 41 to 44 can run vertically parallel to one another and thus save space when the device 10 is in its retracted state.

An elongated and flexible connecting member 55 is assigned to the other or outer end parts 56 of the guide rods 41 to 44, in such a way that the outer end part 56 of the respective rod 41 to 44 is connected to a specific point on the connecting member 55. The end portion 56 of the respective guide rod 41 to 44 is connected to the relevant point of the connecting member 55 in a non-slip manner. If the connecting link 55 is a rope or the like, then the rope 55 can pass through bores in the end parts 56 of the rods 41 to 44. In order to fix the position of the end parts 56 of the respective rod 41 to 44 at the specific point on the cable 55, the simplest way of making knots on the two sides of the respective rod 41 to 44 is on the cable 55. Otherwise, clamps (not shown) or the like can be attached to the connecting member 55 at certain points on the connecting member 55 in order to fix the rod ends 56. A section 61, 62 or 63 of the elongated connecting member 55 extends between two adjacent rods 41 to 44. The length of the respective cable section 61 to 63 determines the distance between the outer end parts 56 of the respectively adjacent guide rods 41 to 44 and thus also the angle between the adjacent guide rods 42 to 44 in their fan-like arrangement, ie when the guide device 40 is in its extended position. The first cable section 61 extends between the first rod 41 and the second rod 42. The second cable section 62 extends between the second rod 42 and the third rod 43. The third cable section 63 extends between the third rod 43 and the fourth rod 44 ,

Among other things, the elongated and flexible connecting member 55 is tensioned by the weight of the inclined rods 42 to 44. The length of the rods 41 to 44 and the length of the cable sections 61 to 63 are chosen so that at least some of the cable sections, e.g. the cable sections 61 and 62 run obliquely downwards or parallel to the inclined canopy 3 when the guide device 40 is in its extended position. The third cable section 63 is located in the area of the front edge 6 of the canopy 3 and runs practically vertically.

At least the upper edge 24 of the shade 11 is connected to the connector 55, the shade 11 hanging from the connector 55 when the device 90 is in its extended position. The connection of the shade dispenser 11 to the connecting member 55 takes place in the illustrated case with the aid of clips 64. These clips 64 can be commercially available clips which have a first section, with the aid of which the clips 64 are fastened to the fabric of the shade dispenser 11. A second bracket section is designed so that it can slide freely on the connecting member 55. Between two neighboring beard brackets 64, the upper edge 24 of the shadow dispenser 11 forms a slack 59 if this is made of a textile material, for example. The number of clips 64 which are connected to the upper edge 24 of the fabric 11 is selected such that the sag 59 between the adjacent clips 64 is as small as possible.

In the area of the third cable section 63, the shadow dispenser 11 is also connected to this cable section 63 by means of the clamps 64, although this would not be necessary to carry the shadow dispenser 11. The clamps 64 in the region of this vertical edge 57 of the shadow dispenser 11 prevent the shadow dispenser 11 from fluttering back and forth in the wind. The fourth rod 44 is also important in this context. Because this rod 44 has a weight with which it loads the shade 11 and thereby stabilizes the position of the lower edge of the shade 11 in particular. This lower edge of the shadow dispenser 11 can be connected to this stabilizing rod with the aid of clamps known per se. Of course, the edge 58 of the shadow dispenser 11 associated with the first rod 41 can also be connected to the first rod 41 for the same reason with the aid of brackets (not shown). However, these clips can also be missing if the cloth in the upper area is directly connected to the upper end of the bar.

If the sloping roof 3 or the like is long, then the upper edge 24 of the shade 11 must also be long. Accordingly, the weight of the fabric 11 also increases. With long top edge 24 of fabric 11 and using only two supporting guide rods 42 and 43, as shown in Fig. 5, the top edge 24 of the fabric could have considerable sag. This is because the resilient link 55, which is the heavy fabric 11 carries, according to the great weight of the fabric 11 would have a considerable own passage 59. Under such circumstances, sun rays would enter the space below the VordacrUs 3 through such a sag. To prevent this, further supporting bars can be used. 6 shows such an additional load-bearing rod 65, which is located between the first rod 41 and the second rod 42: its end part 56 is also connected to the connecting member 55 in the manner described above. The length of this additional load-bearing rod 65 is dimensioned such that the connecting member 55 has its own sag 59, which is as small as possible.

It goes without saying that this shading device 90 likewise has a device which makes it possible to bring this shading device 90 out of its retracted position on the wall 5 into its extended position and back. This device can be designed approximately the same as the cable pulling device 70 already described in connection with FIG. 1. In contrast to the cable pull according to FIG. 1, the deflection roller 71 in the shading device 90 according to FIG. 5 or 6 is above the upper end 56 of the first rod 41 attached to the house wall 5 or to another type of support. The elongated connecting member 55 is guided over this deflection roller 71 and deflected downwards.

FIG. 7 shows a side view of yet another development of the third embodiment of the present device 90 shown in FIG. 5. The device according to FIG. 7 differs from the device according to FIG. 5 firstly in that at least the area of the upper edge 24 of the shade 1 is attached to the upper end portions 56 of the rods 41 to 44. The fabric of the shade dispenser 11 is stretched by the weight of the extended rods 41 to 44, so that the upper edge 24 of the shade dispenser 11 has practically no or no significant sag 59 having. 5, by means of which the upper edge 24 of the fabric 11 was fastened to the flexible connecting member 55. In addition, the cloth 11 along the rods 41 to 44 can be connected to the rods 41 to 44 at a plurality of fastening points 66, specifically stabilizing the position of the cloth 11. These fastening points 66 can be realized, for example, by means of rivets, seams or the like.

Furthermore, the device according to FIG. 7 differs from the device according to FIG. 5 in that only the upper or free end parts 56 of the

Bars 41 to 44 are connected to the flexible connecting member 55, which is deflected around the roller 71. This connection can be realized, for example, with the aid of eyelets 67, which are fastened to the free end parts 56 of the rods 41 to 44. The connecting link 55 can pass through these eyelets 67, the connection between the respective rod 41 to 44 using means known per se, such as e.g. is accomplished by means of knots or the like so that these rod ends cannot slide along the connecting member 55.

A first section 61 of the connecting member 55 extends between the first rod 41 and the second rod 42, this section 61 of the connecting member 55 extending obliquely downward from the deflection roller 71. A second section 62 of the connecting member 55 extends between the second rod 42 and the third rod 43, wherein this section 62 of the connecting member 55 runs, like the first section 61, obliquely downward from the deflection roller 71. The third rod 43 is the longest of the rods 41 to 44. The fourth rod 44 is only so long that the portion of the edge 24 of the shadow dispenser 11 which extends between the third rod 43 and the fourth rod 44 runs practically vertically. Since the connecting member 55 extends along the edge 24 of the shade 11, the last section 63 of the link 55 is also practically vertical. The end of this third link section 63 is connected to the eyelet 67 located here. If you pull on the free end 69 of the link 55, then all the rods 41 to 44 move clockwise. The device 90 is retracted and at the end of this movement all the bars 41 to 44 run parallel to the wall 5.

8 shows a side view of a fourth embodiment of the present device 100 when this device 100 is in its extended position. FIG. 9 shows an enlarged detail from the illustration in FIG. 8. FIG. 10 shows a further development of this fourth embodiment of the present device 100 in a side view

The guide device 60 of the shading device 100 according to FIGS. 8 to 10 has a holding device 75 for the end parts 79 of rods 76, 77 and 78 of this shading device 100 lying inside this device. The holding device 75 is located in the upper area of the present device 100 and it is attached to the wall 5 or to another support element of this device 100. The first rod 76 of the guide device 60 hangs from the holding device 75, that is to say practically in contact with the wall 5 or with another support element of this device 100. The free end part 81 of this first rod 76 can be on the wall 5 or on another Element. The second rod 77 and the third rod 78 of the guide device 60, when the device 100 is in its extended position, run obliquely away from the holding device 75, the angle of inclination of the second rod 77 being smaller than the angle of inclination of the third rod 78 When this device 100 is in its retracted position, all of the bars 76 to 78 of it hang down from the holding device 75 and they run practically parallel to the wall 5. The shadow dispenser 11 of this device 100 is assigned to the rods 76 to 78, in a manner known per se or in one of the ways described above. In the present case, it is sufficient in principle if the upper edge portion 24 of the shade 11 is connected to the third rod 78. However, it can be advantageous if the remaining sections 241 and 242 of the edge region of the shadow dispenser 11 are also connected at least to the free or outer or lower end parts 81 of the rods 76 to 78. It goes without saying that the shadow dispenser 11 can also be connected to the rods 76 to 78, as described in connection with FIG. 7.

This shading device 100 also has a device 85 which makes it possible to bring this shading device 100 from its retracted position on the wall 5 to its extended position and back. This device 85 is also designed as a cable pull and it can be like the cable pull device 70 already described in connection with FIG. 7. The present cable pull device 85 likewise comprises a bendable connecting member 55 which is guided around the roller 71 and then down is distracted. The free end 69 of the connecting member 55 serves to actuate this cable pulling device 85. The section 86 which extends from the deflection roller 71 to the other side only extends to the free end part 81 of the third rod 78, which is connected with a means, for example with an eyelet 67 Attachment of the end portion of this section 86 of the connecting member 55 lying here is provided. The deflection roller 71 is mounted on the wall 5 somewhat higher than the holding device 75. At the same time, the deflection roller 71 is at a distance from the wall 5. This makes it possible for the rods 77 and 78 to move out of their vertical position when one pulls at the free end of the link 55. Instead of the cable pulling devices described above, spindle devices, crank devices etc. can also be used, the devices being able to be driven either by hand or by means of an electric motor.

Since the shading device 100 is located to the side of the roof 3, the deflection roller 71 together with the section 86 of the connecting member 55 can even be located above the roof 3. The shading device 100 is also close to the lateral longitudinal edge of the roof 3. Consequently, the third or topmost rod 78 of this device 100 can lie tightly against the lateral longitudinal edge of the roof 3. In such a case there is almost no gap between the upper edge 24 of the shading device 100 and the roof 3, through which sun rays could get under the roof 3.

If the length of the canopy 3 is greater than the height at which the canopy 3 is mounted on the wall 5, then the length of the pivotable rods 77 and 78 is greater than the height of the space available to them when the device is retracted , For this purpose, the pivotable rods 77 and 78 can be made telescopic. In the case of such a rod 77, the inner end part 79 of the same can be designed as a tube into which the free end part 81 of the same can be moved, which is indicated by a double arrow in FIG. 8. However, the rods, which are too long, can also be designed to be foldable. This means that the lower half 81 of the rod, which is too long, is connected to the upper half 79 thereof via a hinge (not shown), so that the lower half 81 of the rod can be folded up. Finally, it is also possible to arrange a rod which is too long in the holding device 75 in a removable manner, which can be achieved using technical means known per se. So that the rods 76 to 78 can run parallel to each other in the retracted position, the holding device 75 is designed in a special and simple meadow. Between the inner end parts of the first rod

76 and the second rod 77 there is a first hinge 82. The first plate 83 of this hinge 82 is laterally attached to the first rod 76. The second plate 84 of this hinge 82 is laterally attached to the second rod 77. A second hinge 87 is assigned to the opposite side of the second rod 77. The first plate 88 of this second hinge 87 is laterally attached to the second rod 76. The second plate 889 of this hinge 87 is laterally attached to the inner surface of the third rod 77. The pins 91 and 92, which connect the plates 83 and 84 or 88 and 89 of the respective hinge 83 or 87 in an articulated manner, lie in the region of the end faces 93 and 94 of these inner end parts 79 of the rods 76 to 78. This ensures it that the rods

77 and 78 can also be pivoted upward, unhindered if one pulls on the free end 69 of the connecting member 55.

If larger areas of the shadow dispenser 11 are required, then it is expedient to provide at least one further folding rod 95 (FIG. 10), which is arranged between two rods 76 and 77 of the device 100 shown in FIG. 8.

It is understood that one of the shading devices described above can be arranged on each side of the sloping roof 3 for lateral shading. Embodiments of the present device are disclosed above, each of these embodiments having certain features. However, within the scope of the present disclosure are also those embodiments of the present device which combine features from various embodiments described here. The present devices can be used not only in connection with pitched roofs but also in connection with awnings and similar systems.
