Description

The content of the German patent application DE 10 2017 210 535.6 is incorporated herein by reference.

The invention relates to a weatherproof awning with the features specified in the preamble of claim 1.

Conventional awnings, such as articulated arm awnings in particular, are intended only as a sunscreen, since they tend to form a water sack when exposed to rainwater, which can lead to damage or destruction of the awning with increasing weight. In order to prevent the formation of water sacs, such awnings therefore usually have a tendency to be at least 14 ° according to the relevant standard. If there is a deviation from this value, the manufacturer must indicate at which limit of the inclination the water begins to run off.

From the DE 20 2004 014 799 U1 it is already known in connection with the fight against water bag formation to provide the awning fabric of a conservatory awning in the edge region of the awning's awning profile with water drainage openings. Thus, no water bag can form at the lowest point of the awning, since the water can drain through the openings on the roof of the conservatory. A weather protection function is not addressed in this awning.

By public prior use - see http://www.weinor.de/pergotex2/ - A so-called pergola awning is known in which above a protective area, such as a terrace, by a support device, for example in the form of support posts or by lateral attachment to a building, a support frame with lateral guide rails is to be positioned. In this an awning cloth is arranged on and off mobile. The awning fabric is extremely stretched to prevent water bag formation in this way. In addition, parallel to the front rail at regular intervals in the awning support profiles are incorporated, which run in the lateral guide rails for the front rail so as to further counteract sagging of the awning. When retracted, this type of awning merely retracts the frontal profile, in which case the sections of the awning fabric lying between the support profiles form a hanging crease, which leads to a less appealing canopy look. This known pergola awning also requires some propensity to handle the problem of rainfall and water bag formation.

In order to provide a comprehensive weather protection function not only against sunlight, but especially against rain and evasion of a water bag problem, is in the post-published patent application DE 10 2016 218 147 A1 proposed to keep the water-impermeable awning fabric stretched in an at least partially extended position, on the one hand its front edge pointing in the extension direction held in a displaceable mounted on the support frame drop profile and on the other hand its lying parallel to the extension side edges in the support frame are guided. Furthermore, at least one water drain opening is provided in the centrally located area of the awning cloth. Finally, below the at least one water drain opening a water discharge device arranged to remove the running through the at least one water drain opening water from the protected area.

This weatherproof awning is characterized by the above features in that it can be mounted without any inclination, which is used for drainage the then given tendency for water bag formation. Since the awning is held clamped on four sides, a sag of the cloth forms the strongest in its central region, which is also referred to as a so-called "cushion effect". When rainfall, the water runs in this direction, where then one or more water drain openings are provided with a water discharge device arranged underneath. In that regard, so the rainwater is derived from the top of the awning, so that no water bag can form with a corresponding damage potential. At the same time, the protected area under the open awning remains protected against rain, as the rainwater is directed away from the protection area via the drain opening (s) and the drain.

Now, if this type of weatherproof awning is to be greatly expanded in size, the support frame is usually carried out with two or more substantially horizontal frame fields having a common frame strut on their respective adjacent sides. In this common frame strut then the front rail and the awning fabric of each adjacent frame field are performed.

The support frame is still supported only at its four outer corners by columns, the outer frame struts will bend with increasing span. This deflection of the outer, transverse extending to the extension direction of the awning frame struts, which store the common inner frame strut, then it implies that these inner (s) frame strut (s) are lower compared to the parallel outer frame struts in level. As a result, the centrally arranged water drainage openings in the awning would no longer be located at their lowest point and a water sack would form in the event of rain.

To solve this problem, the invention proposes according to the characterizing part of claim 1, the common frame strut, are guided on the awning fabrics and dropouts of two adjacent frame fields, height adjustable execute. Thus, the deflection of this common frame strut holding outer frame struts balanced and both awning again be set exactly horizontal.

In the dependent claims preferred embodiments for the realization of the height-adjustable frame strut (s) are given.

Thus, the common frame strut is formed in two parts from a horizontal, stationary bearing profile and a height-adjustable coupling rail mounted thereon, on which the awning cloths and their dropouts are guided coupled. This allows the functions of stable storage of awning fabric and front rail on the one hand and their height adjustability on the other hand distribute to two different construction elements, which can then be optimally adapted to their task.

A good guidance of the coupling rail on the bearing profile over its entire length can be achieved by the preferred development, which the coupling rail has a hat-shaped cross-sectional area, with which it is placed on a corresponding base region of the bearing profile transversely to its longitudinal direction in a telescopically displaceable manner in the vertical direction.

According to a further preferred embodiment, at least two, preferably three arranged at the two ends and the center of the coupling rail height adjustment devices for the coupling rail are provided. This can be achieved in an adjustment range and accuracy sufficient vertical adjustment of the coupling rail. This can be adjusted by the two end height adjustment devices inclined to horizontal. The third, central Verstellmimik can in turn compensate for a bending of the common frame strut.

A structurally simple, but effective embodiment of the height adjustment device is given by a bearing profile adjustable arranged adjusting screw on which the coupling rail is supported.

In this case, the screw designed as a screw can be adjustably mounted in an internal thread of a respective rotatably mounted counter block, which is inserted in a longitudinal guide of the bearing profile. About this counter block the height adjustment device is stably supported on the bearing profile, whereby the Verstellmimik is insensitive to those high mechanical loads, as caused by wind and Wasserbeaufschlagung the awning.

A further preferred embodiment of the invention provides that the setscrews are connected with their ends facing the coupling rail in such a way with the coupling rail, the tension of the adjusting screws Zug-. and compressive forces are transferable to the coupling rail. This makes it possible for the coupling rail to be placed under tension vertically to its longitudinal direction and thus brought along its longitudinal direction, for example, in an upwardly convex arched state. Thus, a deflection of the common frame strut can be leveled out particularly precisely by a corresponding adjustment of the coupling rail.

Further, the bearing profile may be formed as a hollow chamber profile with an intermediate wall, in which a running in profile longitudinal direction guide groove is formed to form the longitudinal guide for the counter block. This guide groove in the intermediate wall is not only used for holding the counter block, but also ensures stiffening of the intermediate wall and thus the entire bearing profile by the folded profile profile, thus fulfilling an advantageous dual function.

A further development of the invention provides that the adjusting screws engage with their shank a first guide groove in the guide groove of the bearing profile and with its end facing the coupling rail a guide bore in an intermediate wall in the base region of the bearing profile. Thus, the screws are guided not only in the counter block, but at two other longitudinal positions, which ensures a cleanly defined positioning of height adjustment devices.

Finally, according to a further embodiment of the invention, the coupling rail can be designed as a multi-chamber profile, the central chamber forms a extending in profile longitudinal direction support web for supporting the coupling rail on the screws. Here too the support bar again has a dual function by the additional stabilization of the coupling rail profile.

How out Fig. 1 becomes clear, as a whole with 1 designated weather protection awning on a terrace 2 as a protected area S freestanding constructed. As a support device for the awning 1 are four vertical support posts 3, the upper ends of the rectangular, horizontally arranged support frame 4 store. The latter consists of the longitudinal side frame struts 5, 6 and the transversely extending frame struts 7, 8. The rectangle spanned by the frame struts 5, 6, 7, 8 is divided by a common frame strut 30 into two frame panels 31, 32, respectively an awning cloth 9a, 9b of the weatherproof awning 1 consisting of essentially water-impermeable material extends.

How out Fig. 1 and 3 becomes clear, in a transverse side strut 7 each in a housing 10a, 10b a (shown in phantom) cloth shaft 11a, 11b rotatably mounted on the respective awning cloth 9a, 9b wound up during retraction and when extending in the extension direction A ( Fig. 1 ) is again developable from it. With its pointing in the direction of failure A leading edge 12a, 12b, the respective awning fabric 9a, 9b attached to a frontal rail 13a, 13b, with its ends in the usual conservatory awnings known manner corresponding lateral guides 14 in the common frame strut 30 (see Fig. 5 and 6 ) and the longitudinal side frame struts 5, 6 slidably and driven out.

As in Fig. 5 and 6 can also be seen, the awning cloths 9a, 9b with the full length of their parallel to the extension direction A extending side edges 16, 17 in a conventional manner in the manner of a welt slidably held in guide rails 18, 19, so that between the side frame struts 5, 6 and the common frame strut 30 and the Awning cloth 9a, 9b a clamping force can be transmitted and no gap remains. This system is commercially available, for example, in products of the Applicant under the name "tracfix".

In the illustrated in the drawings, extended state of the weatherproof awning 1, the awning cloths 9a, 9b held by the corresponding compounds with frontal profile 13, roller tube 11 and side guide rails 18, 19 are kept very taut, so that gravitationally sets only a very small sag. When rain is applied in this condition, the rainwater accumulating on the awning cloth 9 then runs to the central longitudinal center line M of the awning cloths 9a, 9b, as shown in FIG Fig. 1 indicated by dashed lines. Along this longitudinal center line M - ie in a centrally located region of the respective awning fabric 9a, 9b - now parallel to the extending direction A series of water drainage openings 20 is incorporated into each awning fabric 9a, 9b, which are, for example, round, punched and edges missed or -welded holes can act. Through this, the rainwater can run down and is there in each case by a arranged below the awning cloths 9a, 9b discharge channel 21 (see Fig. 8 ) collected as a drainage device that leads with a slight but sufficient slope to the narrow side frame strut 8. There, the discharge chute 21 opens into a corresponding, in the profile of the frame strut 8 integrated drainage channel, which in turn is drained via a not-shown downpipe in one of the support posts 3.

As from the detail section according to Fig. 8 becomes clear, a groove 24 is formed in the bottom 23 of the discharge channels 21, in which as an accessory for the awning 1 along the discharge channel 21 extending LED light strip 25 is inserted.

In order to align the awning cloths 9 of the weatherproof awning 1 as well as possible horizontally, the support posts 3 may have height-adjustable feet, whereby a coarse alignment can be achieved. For a further adjustment of the spatial position of the awning cloths 9 then, for example, the canvas shaft 11, the front rail 13 and the lateral guides 14, 15 for this adjustable in the frame struts 5-8 be mounted.

A problem with such weather protection awnings 1 with multiple frame fields R1, R2 results from the weight-induced deflection of the two transverse to the extension direction A frame struts 7, 8. Thus, the common frame strut 30 relative to the outer frame struts 5, 6 lower, resulting in a Loss of curvature of the two awning cloths 9a, 9b leads, so that the centrally arranged rows of the discharge openings 20 are no longer at the lowest point of the respective awning fabric 9a, 9b. This has the consequence that a water bag would form, which is to be avoided for the reasons mentioned above.

To solve this problem is in the Fig. 4 to 7 shown in detail height adjustment device for the common frame strut 30 is provided. In principle, the latter is formed in two parts from a load-bearing, horizontal, stationary bearing profile 33 and a coupling rail 34 mounted thereon in a height-adjustable manner, to which the awning cloths 9a, 9b and the outfall profiles 13a, 13b are coupled. In Fig. 5 and 6 are the kederartig recorded in the guides 18, 19 side parts 35a, 35b with the respective awning fabric 9a, 9b shown.

As in particular from the 4 to 6 becomes clear, the coupling rail 34 has a hat-shaped cross-sectional area 36, with which they on a corresponding base portion 37 of the bearing profile 33 is mounted telescopically displaceable transversely to its longitudinal direction in the vertical direction. This vertical telescope displacement is by comparing the Fig. 5 and 6 good to see. The lateral cheeks 38, 39 of the coupling rail 34 in their hat-shaped cross-sectional area 36 are slightly wider apart than the two vertical cheeks 40, 41 of the base portion 37 of the bearing profile 33. Thus, the two profile parts slide in a vertical displacement past each other. Outside at the ends of the cheeks 38, 39 34 box-like profile sections 42, 43 are integrally formed on the coupling rail 34 for reinforcing the coupling rail.

For height adjustment of the coupling rail 34 30 three matching height adjustment devices 44 are provided on the common frame strut 30 and in each case at the end of the frame strut 30 and in the middle.

This height adjustment device 44 is based on the 4 to 6 now explained in more detail. Its core is a designed as a threaded bolt, vertically-adjusting screw 45, which is provided at its lower, to-use end 46 with a hexagon socket head. This set screw 45 is seated with this end 46 in a receiving bore 60 in an upright, flat-parallelepiped-shaped counter block 47 which is inserted into a longitudinal sliding guide 48 at the bottom of the bearing profile 33. This sliding guide 48 is formed on the one hand by a guide groove 49 in the horizontal intermediate wall 50 of the formed as a hollow chamber profile bearing profile 33 and the other by two on the bottom wall 51 inside upstanding webs 52. At the respective positions of the height adjustment device 44 have lower wall 51, intermediate wall 50 and disposed in the base region 37 intermediate wall 53 of the bearing profile 33 each guide holes 54, 55, 56, through which the screw 45 engages through.

On the upper end 57, the coupling rail 34 is supported with a downwardly projecting, in cross-section U-shaped profile support web 58, which is integrally formed from the multi-chamber profile of the coupling rail 34.

By the threaded engagement between the set screw 45 and an internal thread 59 in the mounting hole 60, the height position and thus the coupling rail 34 can be changed upon rotation of the screw 45, as determined by a comparison of Fig. 5 and 7 on the one hand and 6 on the other hand becomes clear. In Fig. 5 and 7 is the lowest position of the screw 45 and thus the coupling rail 34 shown. In Fig. 6 the adjusting screw 45 is displaced upwards and thus pushes the coupling rail 34 upwards, which adjusts accordingly in height. In this way, the two awning cloths 9a, 9b together on the side of the coupling rail 34 - if necessary, also different degrees along the coupling rail 34 - raised and leveled so that their discharge openings 20 are arranged centrally and at the lowest point. Thus, the impact on the awning water without water bag formation can be reliably drained via the drain holes 20.
