Description

[0001] sun protection device

[0002] The invention relates to a sun protection device of the type of an awning with a rotatably mounted fabric roller and with an awning fabric that can be rolled onto and unrolled from the fabric roller. The fabric roller, or the entire sun protection device, is designed and intended for installation in a niche of a building. Furthermore, a drop bar is arranged at a leading edge of the awning fabric.

[0003] Such sun protection devices, or awnings, are widely known, particularly in the form of folding-arm awnings, where the fabric roller is mounted on a support tube or similar structure that is attached to the wall of a building. When the awning fabric unrolls from the roller, which can be done electrically or manually, the folding arms unfold and hold or tension the fabric. Conversely, when the awning fabric is rolled back onto the roller, the folding arms retract.

[0004] To conceal sunshades when rolled up and / or protect them from the elements and dirt, they can be installed in a building niche. However, the niche may not be perfectly regular, especially if its opening is not a perfect rectangle. In such cases, the drop bar cannot be fitted with a uniform gap around the perimeter of the niche, which can be aesthetically displeasing. Furthermore, the depth of the niche may vary, which is also a disadvantage, particularly if the awning or drop bar protrudes partially or completely from the niche. Essentially, every niche will have a slightly different shape, which will inevitably lead to geometric difficulties when fitting sunshades of this type.

[0005] The invention is based on the objective of overcoming the aforementioned problems and further developing a sun protection device of the type defined above in such a way that the best possible geometric adaptation to the niche dimensions and shapes found on site can be made in order to enable a flexible and, in particular, aesthetically pleasing installation of the sun protection device.

[0006] This problem is solved by a sun protection device with a rotatably mounted fabric roller and an awning fabric that can be rolled onto and unrolled from the fabric roller, wherein the fabric roller is designed for installation in a building recess, and wherein a drop bar is arranged or integrally formed on a leading edge of the awning fabric. According to the invention, at least one receiving element is provided for installation in the recess, preferably in operative connection with the fabric roller or with a holder for the fabric roller, and a projecting element is arranged on the drop bar at a rear side facing the building. The receiving element has a recess facing the drop bar, and the projecting element has a projection that is at least partially complementary to the recess. The projection engages in the recess when the awning fabric is rolled up.In principle, a reverse configuration is also possible, in which the aforementioned recess is formed on the drop bar and the aforementioned projection is formed on the "receiving part". In each case, the mounted receiving part is adjustable relative to a position of the fabric roller and / or the projection relative to the drop bar.

[0007] The aforementioned adjustability ensures that the drop bar achieves a defined and adjustable alignment when the projection engages the recess, when the awning fabric is rolled up and the sun protection device is therefore not in operation.

[0008] This defined and adjustable alignment can be adapted so that, with regard to the niche, especially with regard to its front edge or opening, an aesthetically satisfactory alignment is achieved.

[0009] The following further developments of the sun protection device according to the invention have proven to be particularly advantageous in practice:

[0010] In a further development of the sun protection device according to the invention, the receiving part is arranged at at least one end of the fabric roller or a holder for the fabric roller. Preferably, a receiving part is arranged at each end of the fabric roller or the holder for the fabric roller, while two corresponding projection parts are arranged on the drop bar.

[0011] The invention is not limited to the arrangement of the receiving part(s) of the fabric roller or a holder for the fabric roller, e.g., on the aforementioned support tube, although such an attachment may prove advantageous for reasons of stability. In fact, it is only important that the receiving part can be arranged in an adjustable position relative to the fabric roller.

[0012] This can be achieved, for example, by attaching it to a housing or a cover of the sun protection device, or even by independently mounting the receiving part on the building in the area of ​​the niche.

[0013] By using two (or more) mounting and projection parts, a finer degree of adjustment can be achieved, in particular a (slightly) different adjustment at different ends of the sunshade device if the niche is correspondingly uneven.

[0014] In another embodiment of the sunshade device according to the invention, the projecting part is arranged to be displaceable in a first direction transverse to a longitudinal extent of the drop bar with respect to the drop bar. The first direction can, in particular, be the vertical direction (up / down).

[0015] In this way, the position of the drop bar can be adjusted in the first direction, particularly vertically (up or down). This is especially advantageous if both ends of the drop bar have corresponding adjustable positions.

[0016] In yet another embodiment of the sun protection device according to the invention, the receiving part is arranged to be displaceable in a second direction transversely to the fabric roller. This second direction can, in particular, be the horizontal direction parallel to the ground (forward / backward).

[0017] In this way, the position of the drop bar can be adjusted in a second direction, particularly horizontally (forward or backward). This is also particularly advantageous if both ends of the sunshade device or the fabric roller have corresponding adjustable positions.

[0018] In yet another embodiment of the sun protection device according to the invention, the first direction is oriented at least substantially perpendicular to the second direction, as has already been mentioned. It is particularly advantageous if the adjustments in the two directions are independent of each other. This results in a particularly wide range of adjustment possibilities.

[0019] In another embodiment of the sun protection device according to the invention, the receiving part is rotatably or tiltably arranged about an axis running parallel to the fabric shaft.

[0020] This significantly expands the adjustment options, as it also allows the drop bar to be tilted relative to a building front, should the structural conditions in the niche require it. Specifically, a combination of all the adjustment options described so far enables virtually free adjustment of the drop bar's position when the sunshade is rolled up.

[0021] In another embodiment of the sun protection device according to the invention, the axis (i.e. the tilting or rotational axis of the receiving part) is displaceable in a plane transverse to the fabric shaft.

[0022] This is advantageous in order to fully utilize the setting options described above.

[0023] In yet another embodiment of the sun protection device according to the invention, the receiving part is additionally designed as a fabric roller support. For this purpose, it can preferably have a concave section that rests against the fabric roller or the awning fabric rolled onto the fabric roller and thus acts as a kind of support for the fabric roller.

[0024] The receiving part(s) thus advantageously have a dual function, because it / they can also help to counteract any bending or other deformation of the fabric shaft.

[0025] In a preferred embodiment of the sunshade device according to the invention, a scale is provided on the receiving part and / or on the projecting part, which is designed to indicate and make reproducible a respective adjustment position. In this way, the adjustment of the sunshade device can be simplified, for example, if the same setting is to be selected on both sides, or if tests are carried out to find the best possible setting.

[0026] In a particularly preferred embodiment of the sun protection device according to the invention, the receiving part is detachably attached to a holding part, wherein the holding part is fixedly mounted or mountable relative to the fabric roller. The receiving part is displaceable and / or rotatable or tiltable relative to the holding part, preferably as described above. The receiving part can be arranged on only one side of the holding part. Alternatively, it is possible for a corresponding receiving part to be arranged on both sides of the holding part.

[0027] In this design, the retaining element provides the actual fastening of the receiving element relative to the fabric roller and enables its adjustability as described above. The retaining element itself does not need to be adjustable. If a receiving element is provided on both sides of the retaining element, its effective surface can be increased, which is particularly advantageous when used as a fabric roller support. The two receiving elements mentioned can also be connected to form a single unit by means of a common fabric roller support element.

[0028] In a highly preferred embodiment of the sunshade device according to the invention, the receiving part and the holding part are connected by means of at least one first bolt or the like, preferably a first screw bolt, which is guided through a first elongated hole in the receiving part. The elongated hole particularly allows the receiving part to be displaceable relative to the holding part. It extends – with its long axis – preferably in the second direction.

[0029] If the first bolt is designed as a screw bolt that rests forcefully against an edge of the first elongated hole, it can be (easily) loosened to allow the desired displacement and then tightened again to secure the desired relative position of the receiving part and the holding part.

[0030] An adjusting screw may be provided by means of which the first bolt in the first elongated hole can be adjusted.

[0031] In another highly preferred embodiment of the sunshade device according to the invention, the receiving part and the holding part are connected by means of at least one second bolt or the like, which is spaced apart from the first bolt. The second bolt can also preferably be designed as a screw bolt. The second bolt is guided through a hole in the receiving part to allow the receiving part to rotate or tilt relative to the holding part. This rotation or tilting accordingly takes place about an axis defined by the second bolt, parallel to the fabric roller.

[0032] If the second bolt is designed as a screw bolt, it can be (easily) loosened to allow rotation or tilting of the receiving part, and then tightened again to secure the desired relative position of the receiving part and the holding part.

[0033] An adjusting screw may be provided by means of which the second bolt can be adjusted in the second elongated hole.

[0034] In yet another, highly preferred embodiment of the sun protection device according to the invention, the retaining part has a second elongated hole through which the second bolt is guided in order to determine the position of the axis depending on a displacement of the receiving part.

[0035] In this way, the rotatability or tiltability of the receiving part is fully maintained when it is displaced (horizontally). The second elongated hole is preferably oriented essentially parallel to the first elongated hole. In practice, this relative orientation will change if the receiving part is rotated or tilted relative to the holding part.

[0036] In yet another, highly preferred embodiment of the sun protection device according to the invention, the retaining part has a third elongated hole through which the first bolt is guided in order to allow the receiving part to be rotated or tilted relative to the retaining part about the axis.

[0037] Although in principle a (screw) bolt through the receiving part in conjunction with a slotted hole in the holding part may be sufficient for the desired adjustability, it was found that the described configuration with two (screw) bolts and several slotted holes provides improved stability of the relative arrangement of the holding part and receiving part.

[0038] Another embodiment of the sunshade device according to the invention provides that the first and third elongated holes are oriented essentially perpendicular to each other. The exact relative orientation of the two aforementioned elongated holes depends on the rotation or tilting of the receiving part relative to the holding part.

[0039] Such a configuration provides the greatest possible freedom in adjusting the position of the receiving part relative to the holding part.

[0040] Furthermore, in a further development of the sun protection device according to the invention, it can be provided that the second and third elongated holes are oriented perpendicular to each other. This relative orientation of the two aforementioned elongated holes does not depend on the rotation or tilting of the receiving part relative to the holding part, because these two elongated holes are formed in the holding part.

[0041] Such a configuration provides a further contribution to the ability to adjust the position of the receiving part relative to the holding part.

[0042] Another embodiment of the sun protection device according to the invention provides that the retaining part has an opening, preferably with a rectangular cross-section, with which it is positively locked and rotationally fixed onto a support tube of the sun protection device that is mounted or mountable in the niche. In addition to the retaining part, the fabric roller can preferably also be mounted on the support tube.

[0043] The support tube creates a stable connection point for the holding part and, thanks to its regularly rectangular cross-section, allows for a simple, rotationally fixed fixing of the holding part.

[0044] Yet another embodiment of the sun protection device according to the invention provides that the projection is asymmetrically designed with respect to the direction of travel of the awning fabric or the drop bar. Preferably, the projection can have a first flank, most preferably the upper flank in the installed state, which is in particular essentially straight and oriented parallel to the direction of travel. Preferably, the projection also has a second flank, most preferably the lower flank in the installed state, which is in particular convexly curved. One tip of the projection can be rounded. The recess in the receiving part is correspondingly complementary.

[0045] It has been shown that with such a shaping of the protrusion and recess, a particularly gentle and careful engagement of the protrusion into the recess occurs, without excessive wear or even damage, jamming or tilting.

[0046] A further development of the sun protection device according to the invention provides that a groove with an undercut is provided on the side of the drop bar facing the awning fabric, extending in the longitudinal direction of the drop bar. An engagement element, which is connected or connectable to the projection part, engages positively in this groove. The relative position of the engagement element and the projection part is adjustable, preferably in a direction transverse to the longitudinal direction of the drop bar, i.e., transverse to the groove, particularly in the first direction mentioned above.

[0047] This allows for the simple implementation of the height adjustability of the drop bar described above. The drop bar can also be fitted with an outer cover if desired for aesthetic reasons, e.g., to adapt it to a specific niche dimension.

[0048] Further features and advantages of the invention will become apparent from the following description of exemplary embodiments with reference to the drawing. Here, identical reference numerals denote identical or at least equivalently functioning elements.

[0055] Fig. 8 shows different views of the projection part of the sunshade device from Figure 1 to illustrate the corresponding adjustment options.

[0056] Figure 1 shows a sun protection device 1 in the form of a folding-arm awning with two folding arms 2 in a partially extended state. The sun protection device 1 comprises a rotatably mounted fabric roller 3 and an awning fabric 4, which can be wound onto and unwound from the fabric roller 3 and is indicated only by dashed lines in Figure 1. The arrows ER and AR in Figure 1 symbolize a retraction and an extension movement of the sun protection device 1, respectively. The entire sun protection device 1, and in particular the fabric roller 3 as well as a mounting system not visible in Figure 1, including a so-called support tube, is mounted in a niche 5 of a building (not shown further), so that the sun protection device 1 is completely contained within the niche 5, at least in its retracted state.A drop bar 6 is arranged at a leading edge of the awning fabric 4, which, when the sunshade 1 is retracted, largely closes the recess 5 to the outside. It is desirable that the drop bar 6 has a defined and, above all, adjustable orientation relative to the front recess opening, in order to compensate for inaccuracies on the building site, even after the sunshade 1 has been installed.

[0057] For this purpose, at least one receiving part 7 is provided for mounting in the niche 5, preferably in operative connection with the fabric roller 3 or with a bracket for the fabric roller 3, which will be explained in more detail with reference to the following figures. Furthermore, a projection part is arranged on the rear side of the drop bar 6 facing the building, which, however, is not visible in Figure 1 due to the chosen method of representation. The receiving part 7 has a recess facing the drop bar 6 (at reference numeral 8, see also Figures 2-5), and the projection part has a projection 11 shaped complementarily to the recess 8, which engages in the recess 8 when the awning fabric 4 is wound up, thus positioning the drop bar 6 relative to the niche 5. Because the mounted receiving part 7 or...Since the receiving part 8 is adjustable relative to a position of the fabric roller 3 and / or the projecting part relative to the drop bar 6, a desired, and in particular aesthetically pleasing, alignment of the drop bar 6 with respect to the niche 5 can be achieved in this way. Preferably, at least one receiving part 7 is arranged at each end of the fabric roller 3, which is not visible in Figure 1.

[0058] The details of the design, in particular the receiving part 7 and the recess 8, will now be discussed in more detail with reference to Figures 2 ff. For the sake of clarity, not all reference symbols are shown in every figure.

[0059] Figure 2 shows in three partial illustrations a) to c) side views of the sun protection device 1 from Figure 1 with a viewing direction along an axis of the fabric shaft 3 to illustrate a first type of adjustability.

[0060] Reference numeral 9 denotes a bracket for the fabric roller 3, wherein the bracket 9 may in particular comprise a support tube, which is not clearly visible in Figure 2 and which runs parallel to the fabric roller 3 within the recess 5, where it is fixed to the building. Reference numeral 10 shows the aforementioned projection part, which is attached to the rear of the drop bar. The projection part 10 has a projection 11 (a "nose"), the exact shape of which will be described below. The projection part 10, and thus also the projection 11, is displaceable on the drop bar 6 in a (first) direction transverse to a longitudinal extension of the drop bar 6 and correspondingly transverse to the axis of the fabric roller 3, and can be fixed in its respective adjustment position on the drop bar 6. Preferably, such a projection part 10 is arranged at both ends of the cloth shaft 3 j, which cannot be seen in Figure 2.

[0061] It has already been pointed out that the receiving part 7 has the recess 8, which is shaped complementarily to the projection 11. As a result, when the awning fabric 4 is wound up, the projection 11 engages precisely in the recess 8 and thus positions the drop bar 6 relative to the niche 5, as shown in partial figures a) to c) of Figure 2 for three different positions of the projection part 10 on the drop bar 6.

[0062] In Figure 2a, the projection 10 is arranged in an approximately central position on the drop bar 6. Accordingly, the drop bar 6 is approximately equidistant from an upper edge 12 of the niche 5 and a lower edge 13 of the niche 5.

[0063] In Figure 2b, the projection 10 is arranged in an upper position on the drop bar 6. Accordingly, the drop bar 6 (with the receiving part 7 with the recess 8 remaining in its original position) is shifted downwards, resulting in a greater distance A' of the drop bar 6 from an upper edge 12 of the niche 5 compared to the distance A'' from the lower edge 13 of the niche 5.

[0064] In Figure 2c, the projection 10 is arranged in a lower position on the drop bar 6. Accordingly, the drop bar 6 (with the receiving part 7 with the recess 8 remaining in its original position) is shifted upwards, resulting in a smaller distance A'' of the drop bar 6 from an upper edge 12 of the niche 5 compared to the distance A' from the lower edge 13 of the niche 5.

[0065] This results in the sun protection device 1 or the drop bar 6 being able to be divided in a direction z transverse to the fabric shaft axis (more precisely in the direction ± z, as shown).

[0066] As can be seen from Figure 2, the receiving part 7 is also designed as a fabric shaft support and has a concave contact section at reference sign 14, which is peripherally in contact with the fabric shaft 3 or the awning fabric 4 in order to support it.

[0067] Figure 3 shows in three partial illustrations a) to c) side views of the sun protection device 1 from Figure 1 with a viewing direction along an axis of the fabric shaft 3 to illustrate a second type of adjustability, which consists in a further direction x or ±x transverse to the fabric shaft axis, wherein this further direction ±x is oriented perpendicular to the direction ±z shown in Figure 2.

[0068] As can be seen in Figure 3, and as was already apparent in Figure 2, the receiving part 7 is mounted on a retaining part 15, which has a rectangular opening 16. This opening allows the receiving part to be arranged in a rotationally fixed, form-fitting manner on the similarly rectangular support tube for the fabric roller 3, which in turn is part of the aforementioned bracket 9. The retaining part 15 extends from the area of ​​the bracket 9 primarily downwards (direction -z) and then forwards (direction +x), being positioned behind the receiving part 7 as seen in Figure 3. Preferably, corresponding arrangements are found at both ends of the fabric roller 3.

[0069] The receiving part 7 is detachably fastened to the holding part 15 by means of two screw bolts 17, 18, preferably with internal hexagon drive or the like. The screw bolt 17 is guided in an elongated hole 19 in the receiving part 7, which, in the state shown in Figure 3, extends in the ±x direction. The elongated hole 19 has a circumferential countersunk shoulder 20, which serves as a bearing surface for the screw bolt 17 or its head (not labeled). For the other screw bolt 18, a (not labeled) hole is provided in the receiving part 7 and an elongated hole in the holding part 15, the latter being not visible due to the chosen illustration. In the state shown in Figure 3, the elongated hole in the holding part 15 is oriented parallel to the elongated hole 19. The screw bolts 17, 18 are secured against falling out in a known manner, e.g. by means of a suitable nut, which is not shown or not apparent.

[0070] If the screw bolts 17, 18 are now (slightly) loosened, the receiving part 7 can be moved in the direction of the two aforementioned elongated holes, in particular elongated hole 19, in the ±x direction. After retightening the screw bolts 17, 18, it is fixed in the respective position relative to the retaining part 5 and corresponding to the fabric roller 3, thus ensuring an adjustment of the drop bar 6 in the ±x direction, as shown.

[0071] In Figure 3a), the receiving part 7 is arranged in a central position in the elongated hole 19. This results in an approximately flush finish of the drop bar 6 with a front opening of the niche 5 between the upper edge 12 and the lower edge 13.

[0072] In Figure 3b), the receiving part 7 is arranged in a forward position on the holding part 15 (the elongated hole 19 is shifted completely in the +x direction with respect to the screw bolt 17). Accordingly, the drop rod 6 is shifted forward out of the recess 5.

[0073] In Figure 3c), the receiving part 7 is arranged in a rear position on the holding part 15 (the elongated hole 19 is shifted completely in the -x direction with respect to the screw bolt 17). Accordingly, the drop rod 6 is shifted rearward into the recess 5.

[0074] This results in the sun protection device 1 or the drop bar 6 being able to be adjusted in a further direction ±x transverse to the fabric shaft axis (more precisely in direction ±x, which is also perpendicular to the direction ±z, as shown).

[0075] Figure 4 shows in three partial illustrations a) to c) side views of the sun protection device 1 from Figure 1 with a viewing direction along an axis of the fabric shaft 3 to illustrate a third type of adjustability, which consists in a rotation or tilting of the receiving part 7 about the fabric shaft axis or about an axis parallel to the fabric shaft 3, wherein this further axis is defined by the screw bolt 18 (see Figure 3).

[0076] As can be seen in Figure 4, sub-figures b) and c), the retaining part 15 has a further elongated hole or slot 21, which is oriented in the ±z direction. When the receiving part 7 is oriented as in Figure 4a), the elongated hole 19 and the slot 21 are perpendicular to each other.

[0077] If the screw bolts 17, 18 are now (slightly) loosened, the receiving part 7 can be rotated or tilted around the screw bolt 18 according to the (double) arrow D, whereby the screw bolt 17 moves accordingly within the elongated hole 19 and the slot 21. The amplitude or a maximum degree of rotation / tilting is determined by the length of the elongated holes 19, 21. After retightening the screw bolts 17, 18, the receiving part 7 is fixed in the respective position relative to the retaining part 5 and according to the fabric roller 3, thus providing an additional adjustment of the drop bar 6, as shown.

[0078] In Figure 4a), the receiving part 7 is arranged in a central position in the elongated hole 19 and in a central rotational position with respect to the screw bolt 18, i.e., the (rotational) axis. Accordingly, the drop bar 6 is approximately flush with the opening of the recess 5 between the upper edge 12 and the lower edge 13, with the drop bar 6 also being oriented substantially exactly in the ±z direction (see Figure 2a).

[0079] In Figure 4b), the receiving part 7 has been tilted counterclockwise around the screw bolt 18, i.e., around the (rotational) axis defined by it. Consequently, due to the rotation, the screw bolt 17 has moved backward in the elongated hole 19 and simultaneously downward in the slot 21, because its distance from the pivot point remains constant. As a result, the drop rod 6 has been displaced forward out of the recess 5 in its lower region, while in its upper region it remains approximately flush with the edge of the recess 5.

[0080] Conversely, in Figure 4c, the receiving part 7 has been tilted clockwise around the screw bolt 18, i.e., the (rotational) axis. Accordingly, due to the rotation, the screw bolt 17 has moved backward in the elongated hole 19 and simultaneously upward in the slot 21. As a result, the drop rod 6 has been displaced forward out of the recess 5 in its upper region, while in its lower region it remains approximately flush with the edge of the recess 5.

[0081] This results in an additional adjustability of the sunshade device 1 or the drop bar 6 in a further direction by rotating it about a direction parallel to the fabric roller axis, the exact position of the axis of rotation depending in particular on the adjustability according to Figure 3. In other words: the axis of rotation is displaceable in a plane, namely the x-z plane, transverse to the fabric roller 3, which extends accordingly in the ±y direction (not marked).

[0082] All adjustment options described so far can be combined virtually arbitrarily within their respective limits. It is also possible to allow only a subselection of the described adjustments, e.g., only the linear adjustments in the x and z directions according to Figures 2 and 3. Furthermore, different settings can be made at each of the two ends of the fabric roller 3 if the geometry of the niche 5 requires it. Figure 5 shows several isolated views or partial illustrations a) to h) of the receiving and holding parts 7 and 15 of the sunshade device from Figure 1 to illustrate the various adjustment options. To simplify the illustration, all other components of the sunshade device have been omitted.

[0083] Partial figure 5a shows a preferred embodiment in which a retaining part 15 is connected on one side to a receiving part 7. The concave contact section 14, already explained with reference to Figure 2, in which the receiving part 7 also serves as a fabric roller support and which is peripherally in contact with the fabric roller 3 or the awning fabric 4, advantageously extends over the receiving part 7 and over the retaining part 15 for the purpose of widening it. A coating or a cover or a continuous, one-piece covering 22 can be provided in the contact section 14, which functions as a fabric roller support element to protect the fabric roller or the awning fabric from damage.

[0084] The following partial illustrations 5b) to 5h) further illustrate the adjustment possibilities already described above, which result from a relative displacement of the holding part 15 and the receiving part 7.

[0085] Partial figure 5b) shows a basic position: screw bolt zen 17 arranged centrally in the elongated hole 19; no rotation about the screw bolt zen 18 .

[0086] Partial figure 5c shows a position shifted in the +x direction: screw bolt 17 is arranged off-center to the left in the elongated hole 19; no rotation about the screw bolt 18.

[0087] Partial figure 5d) shows a position shifted in the -x direction: screw bolt 17 is arranged off-center to the right in the elongated hole 19; no rotation about the screw bolt 18.

[0088] Partial figure 5e) shows a position shifted and tilted in the -x direction: screw bolt 17 is arranged off-center to the right in the elongated hole 19; additionally, rotation in a clockwise direction about the screw bolt 18 (screw bolt in slot 21, cf. figure 4, moved upwards).

[0089] Partial figure 5f) shows another position shifted in the -x direction and simultaneously tilted: screw bolt 17 arranged off-center to the right in the elongated hole 19; additionally, rotation counterclockwise around the screw bolt 18 (screw bolt in slot 21, cf. figure 4, moved downwards).

[0090] Partial figure 5g) shows a position shifted and tilted in the +x direction: screw bolt 17 is arranged off-center to the left in the elongated hole 19; additionally, rotation in a clockwise direction around the screw bolt 18 (screw bolt in slot 21, cf. figure 4, moved upwards).

[0091] Partial figure 5h) shows another position shifted and simultaneously tilted in the +x direction: screw bolt 17 is arranged off-center to the left in the elongated hole 19; additionally, it is rotated counterclockwise around screw bolt 18 (screw bolt in slot 21, cf. Figure 4, moved downwards). A scale (not shown here) can be provided in the area of ​​the elongated hole 19 to offer a visual orientation aid, with which the position of screw bolt 17 within the elongated hole 19 can be specified quantitatively and reproducibly.

[0092] Figure 6 shows a detailed view of the back of the drop bar 6 of the sunshade device from Figure 1, together with a projection 10 attached to it, which in turn includes the projection 11. At the top of the drop bar 6 is a keder groove 23 for attaching a keder provided on the awning fabric. At reference numeral 24, a groove extending longitudinally along the drop bar 6 with an undercut 25 on both sides is arranged, into which an engagement element (sliding block) 26 engages positively, thus ensuring that the projection 10 is attached to the drop bar 6 in the specified direction ±y. The direction ±y runs parallel to the longitudinal direction or extent of the drop bar 6. A scale 27 can be seen on the projection 10, which indicates the relative position of the projection 10 with respect to the drop bar 6. The groove shows 24.This makes the aforementioned position quantifiable and easily reproducible.

[0093] It has already been emphasized that preferably two such projecting parts 10 are arranged on the drop bar 6, at each end of a .

[0094] Figure 7 shows in partial illustrations a) to c) three side views of the drop bar 6 of the sun protection device from Figure 1 together with a projection part 10 attached to it to further illustrate in particular the adjustability in the ±z direction already described with reference to Figure 2.

[0095] The sliding block 26, which engages in the groove 24, can have a spring element (not visible) so that the projection 10 can be moved essentially freely in the ±z direction (and also along the groove 24 in the ±y direction, see Figure 6) by (manually) lifting it off the drop bar 6. After release, the spring force ensures that the projection 10 remains securely in the desired position. However, the invention is not limited in this respect; in particular, the projection 10 can also be screwed to the drop bar 6 or otherwise fixed to it, e.g., clipped or latched.

[0096] The scale 27 indicates a relative position of the projection part 10 with respect to the drop bar 6 or the groove 24, as already mentioned.

[0097] In partial illustration a) of Figure 7, the projection part 10 is in a lowered position relative to the drop bar 6. Accordingly, when the projection 11 engages in the recess 8 of the receiving part 7 (see, for example, Figure 1 or 2), the drop bar 6 will assume a relatively high position relative to the niche 5, approximately as shown in Figure 2c).

[0098] In partial figure b) of figure 7, the projection part 10 is in a central position with respect to the drop bar 6. Accordingly, when the projection 11 engages in the recess 8 of the receiving part 7 (see, for example, figure 1 or 2), the drop bar 6 will also assume a central position with respect to the niche 5, approximately as shown in figure 2a).

[0099] In partial figure c) of figure 7, the projection part 10 is in a raised position relative to the drop bar 6. Accordingly, when the projection 11 engages in the recess 8 of the receiving part 7 (see, for example, figure 1 or 2), the drop bar 6 will assume a relatively low position relative to the niche 5, approximately as shown in figure 2b).

[0100] Figure 8 shows different views of a projection section.

[0101] 10 of the sun protection device from Figure 1 for the purpose of illustrating the corresponding adjustment options.

[0102] Partial illustration a) of Figure 8 shows the projection 10 in a rear, perspective view. The engagement element (the sliding block) 26 is clearly visible here, which is arranged on two pins 28 and / or screws that can move within corresponding elongated guides 29 by a certain amount in the ±z direction relative to the rest of the projection 10. This allows the projection 11 to be displaced according to the scale 27.

[0103] This is also shown again in the side views according to partial figures b) to d) of Figure 8, which in this respect correspond to partial figures a) to c) of Figure 7.

[0104] Finally, let us examine the shape of the projection in more detail using partial illustrations b) to d) of Figure 8.

[0105] 11. This is asymmetrically designed with respect to an axis S, which is transverse to the longitudinal direction of the drop bar 6 (see Figures 6 and 7). Accordingly, the projection 11 is also asymmetrically designed with respect to the extension and retraction directions ER, AR of the awning fabric 4 (see Figure 1) and the drop bar 6 (see Figure 1). The projection 11 is rounded at its tip 30. Further along, it has a first flank 31, which forms an upper flank in the installed state. This first flank 31 is essentially straight and oriented parallel to the extension and retraction directions ER, AR (see Figure 1). The projection 11 also has a second flank 32, which forms the lower flank in the installed state and is convexly curved. The recess 8 (see, for example, Figure 7) in the receiving part 7 (see Figure 1)Figure 7) is designed in a correspondingly complementary manner in order to be able to accommodate the projection 11 even after an adjustment (displacement, rotation or tilting) without tilting or the like, as has already been pointed out several times.
