Abstract

The awning (10) has an additional sun guard with two awning arms (20) that are pivotally mounted at the building side by the joints (22) about vertical axis (24) . The edges (16,18) of awning cloth (15) are fixed on a winding shaft (17) and a drop rail (19). A guide profile is extended along longitudinal direction of drop rail on which the awning arms are movably mounted.

Description

The invention relates to an awning with additional sun protection and an additional sun protection for an awning.

In practice, there is always the desire to attach to awnings an additional sun, wind or visual protection, which depends on the awning approximately vertically.

This reveals the DE 33 15 504 A1 a swing frame for an awning with a side curtain. The awning comprises a frame pivotable about a horizontal axis. Between the frame and the building ropes are stretched, on which run eyelets, which carry a curtain.

Next, the utility model G 84 30 086 U1 discloses an awning with a fabric and an associated support to which the fabric is anchored. The carrier is formed by a cylinder profile with two longitudinal bores. The longitudinal bores are slotted towards the cylinder jacket. The awning material is anchored with a piping in one of these holes. The other hole may carry a vertically hanging curtain.

The DE 37 44 590 C1 discloses an awning with obliquely arranged rails, on which support rods of a fabric curtain are suspended movably along the rails. The mounting rails carry the fabric curtain, which is initially horizontal or light along the mounting rails sloping downwards and then hanging down from the free end of the mounting rails down.

The DE 200 09 461 U1 discloses an anti-glare curtain formed in the manner of a vertically oriented articulated arm awning. From a vertically oriented winding shaft, an anti-glare curtain extends like a wall to a vertical Ausschubstab whose lower end is supported by a wheel on the ground. Between the housing of the winding shaft and the extension rod articulated arms are arranged.

The DE 1 896 00 U1 discloses a sunshade that is to be moved vertically in front of a window and, if necessary, to fold on a circular arc away from it.

Next discloses the DE 202 09 746 U1 a side awning, which includes an arm to be folded away from a house wall about a vertical axis. This arm carries a curtain, for example in the form of a Roman blind.

The design of awnings and possibly an additional sunscreen is a persistent problem. Several different requirements have to be united with each other, whose individual solutions lead in different directions. For example, the system is designed to be easy to use, easy to retrofit, and robust.

It is an object of the invention to provide an awning and a sunshade that meet these requirements.

• Die erfindungsgemäße Markise ist besonders robust. Sie umfasst zwei Markisenarme, die gebäudeseitig an Gelenken um vertikale Achsen schwenkbar gelagert sind. Die vom Gebäude weg liegenden Enden der Markisenarme laufen in oder an einem Führungsprofil der Fallschiene, die ihrerseits das Markisentuch auszieht. Das Markisentuch ist mit seinem gebäudeseitigen Ende von einer Wickelwelle aufgenommen. Die Fallschiene und die Wickelwelle spannen das Markisentuch zwischen einander.

This object is achieved with the awning according to claim 1 and / or the sunshade for an awning according to claim 5 solved:

• The awning according to the invention is particularly robust. It comprises two awning arms, which are pivotally mounted at the joints on joints around vertical axes. The ends of the awning arms lying away from the building run in or on a guide profile of the drop rail, which in turn pulls out the awning cloth. The awning cloth is taken with its building-side end of a winding shaft. The drop rail and the winding shaft clamp the awning cloth between each other.

Preferably, the removal of the awning fabric under the action of a spring bias. For example, the awning arms may be resiliently biased away from the building. The winding shaft may be provided with a manual drive or a motor drive which rotates the winding shaft in the winding or in the unwinding direction.

Preferably, the guide profile has a rectangular guide channel, for example, in which one or more rollers of the awning arms run. For example, the guide profile may be a longitudinally slotted rectangular hollow profile.

The basic concept of the awning arms swiveling away from the building approximately horizontally provides a simple and clear, yet robust, basic structure, with which the awning fabric can be taut without any problem. Even with moderate spring forces the drop rail can absorb high Tuchzugkräfte. When the angle included between the drop rail and the awning arms approaches a right angle, despite decreasing, acting on the awning arms Swinging moment ever greater Tuchzugkräfte be absorbed. The storage of the ends of the awning arms in or on the drop rail by wheels or rollers avoids unnecessary friction and thus facilitates the complete swinging out of the awning arms despite relatively low, easily manageable spring forces.

This concept makes it possible to design the actuation springs so that they are almost relaxed when the awning arms are spread (almost) at a right angle away from the building. This leads to a considerable ease of assembly. When installing the awning, the awning mechanic does not need to tension the actuation springs or only slightly. They are only stretched by applying the awning arms to the building.

The awning can be equipped with an additional sunscreen. This can for example be attached to the drop rail or on the awning arm. Preferably, it is housed in a cassette housing, wherein the cassette housing preferably has only at its two end faces fastening devices for attachment to the awning. This concept allows the variable use of the sunshade alternatively on the drop rail or on the awning arm. This in particular if the fastening devices allow a certain pivotal movement of the cassette against its associated suspension, at least in principle. While one end of the cassette is located at the pivotal mounting at a fixed height, the other end of the cassette can pivot up and down. Thereby, the cassette can be attached to the in use and in the building-splayed state, preferably slightly obliquely downwardly extending, awning arm, wherein one of the ends of the cassette is pivotable and the other Height adjustable is mounted on the awning arm. For height adjustment can serve a lockable spring winding apparatus, which has been found to be particularly user-friendly.

The cassette according to the invention can, in particular by the nature of its attachment optionally on the drop rail or on the preferably rigid, i. hingeless awning arms are attached.

In FIG. 1 a mounted on a building wall 10 awning 11 is illustrated, which carries an additional sunshade 12. This is, as easily recognizable, attached laterally. Additional additional sunshades 13, 14 may be attached to the end of the awning 11 away from the building wall 10. While the awning 11 extends approximately horizontally or slightly sloping away from the building wall 10, to overshadow a place, such as a seat, appropriate cloths or sheets of additional sunscreen 12, 13, 14, preferably vertically from the awning 11 down.

To the awning 11 includes an awning fabric 15, the near-building end 16 is fixed to a winding shaft 17. The other end 18 is attached to a drop rail 19, e.g. taken in a corresponding Kedernut. The drop rail 19 is preferably arranged horizontally and parallel to the winding shaft 17.

The drop rail 19 is made of, for example FIG. 3 visible awning arms 20, 21 worn, which is taken on the building wall 10 in corresponding bearings 22, 23 and pivotally mounted about a vertical or slightly inclined to the vertical axis of rotation 24. The bearing 22 is arranged below a winding shaft 17 receiving awning box 25. It may be connected to the building wall 10 and / or the awning box 24. Preferably, the awning box 24 and the storage for the awning arms 20, 21 form a structural unit that is hung in pre-assembled consoles.

FIG. 4 illustrates the storage 22 separately. As can be seen, the awning arm 20 is biased by a spring 55 in the pivoting direction away from the wall 10. The spring 55 may be a tension spring, which is outside the pivot axis 24 engages an end piece 56 of the arm 20 and thus generates a pivoting moment for the awning arm 20 (21).

The remote from the building wall 10 end of the awning arm 20, 21 carries a roller assembly 26, 27, in FIG. 1 indicated schematically and better off FIG. 5 is apparent. It comprises at least one, preferably at least two rollers 28, 29, which are preferably rotatably mounted about an approximately perpendicular axis 30. They are supported by a tab 31 extending from the end of the awning arm 20, 21 away from the respective support 22, 23.

The drop rail 19 is formed as a guide profile. For this purpose, it has, for example, a longitudinally extending through the drop rail 19 interior 32, which, as shown, may be rectangular or otherwise shaped. He is on its building wall 10 facing side accessible through a slot 33 through which the tab 31 extends therethrough. The roller assembly 26 is preferably disposed in the interior 32 and may run along the drop rail 19. The vertical boundary walls of the interior 32 form tracks for the rollers 27, 28th

The tab 31 is preferably part of a fitting 34, for example made of metal, which is attached to the free end of the awning arm 20 (or 21). The fitting 34 is separately in FIGS. 6 and 7 illustrated. As can be seen, it may have a downwardly extending extension 35, which may serve to secure the additional sunshade 12. For this purpose, an opening 36 may be formed in the extension 35, for example in the form of a rectangular slot. The opening 36 at the bottom limiting web 37 is in cross section (see FIG. 7 ) is preferably rounded, for example circular. He is horizontal arranged and thereby formed a horizontal pivot bearing for the additional sun protection 12th

While the fitting 34 is used to support the additional sunshade 12 on the awning arm 20 or 21, may be provided on the drop rail 19, a downwardly extending extension 38, which is also the storage of an additional sunscreen (13,14 in FIG. 2 ) serves. This extension 38 may be formed, for example, as a straight extension of the front wall of the interior 32 down. At this extension 38, one or more brackets 39 may be screwed, which serve to receive the respective sunshade 13 or 14 and to have a slot-like passage 40. An end-side end piece of the drop rail 19 can also serve as a support for mounting the sunshade 13 or 14.

On the drop rail 19 further structures may be formed, for example, a Kedernut 41 for receiving the in FIG. 2 schematically indicated flounces 42.

The additional sunshade 12 preferably coincides with the sunshade 13, 14. The uniform sunshade 12, 13, 14 can optionally be attached to the drop rail 19 or the awning arms 20, 21. The following description of the sunshade 12 applies equally to the other sunshades 13 and 14.

To the sunshade 12 belongs, as from the FIGS. 7 and 8th shows a cassette 43, which is designed as a hollow box, as a closed end tube profile or downwardly open U-profile. In its interior, for example, a winding shaft 44 is housed with a wound roller blind is provided and forms a downwardly extendable roller blind. Alternatively, other shading means such as a horizontal or vertical blind slat curtain, a folding blind or the like may be accommodated in the cassette 43.

The cassette 43 is only at its two ends 45, 46 ( FIGS. 7 and 8th ) provided with fastening means 47, 48, preferably in the form downwardly curved hook. The hooks are preferably formed by downwardly curved flat profiles with a rectangular cross-section. The rectangular cross section corresponds to a necessary clearance the cross section of the opening 36th

While the hook 47 is hooked into the opening 36 of the fitting 34, the hook 48 is connected to a height-adjustable suspension 49. To this belongs preferably a receiving lug 50, in which the hook 48 engages, wherein the suspension lug 50 is supported by a pulling means 51. The traction means 51 may be a rope, a wire or a band, for example a plastic band or preferably a steel band. This is a, for example, arranged on the awning arm 20 or 22 winding device 52 assigned, this meadow by means of a locking device is preferably blockable. It has a take-up reel 53, which is biased by a not further illustrated spring in the winding direction. A release button 54 may be provided to release the locking device to allow rotation of the reel spool 53. The locking device may be formed by a slider which acts on the reel spool 53 to lock it. The trigger button 54 may be manually operable. Preferably, the winding moment acting on the reel spool 53 is so great that the tensile force on the traction means 51 is the weight of the sunshade 12 easily overcomes.

• Die Markise 11 ist in der schematischen Darstellung nach Figur 5 in nicht ausgezogener Position dargestellt. Um sie auszufahren wird die Wickelwelle 17 so angetrieben, dass das Markisentuch 15 abgewickelt wird. Wie Figur 3 zeigt, schwenken dabei die Markisenarme 20, 21 unter der Wirkung ihrer jeweiligen Feder 55 von der Gebäudewand 10 weg. Dabei fahren die Rollenanordnungen 26, 27 in der Fallschiene 19 voneinander weg, wobei die Fallschiene 19 durch das Markisentuch 15 und die Markisenarme 20, 21 parallel zu der Gebäudewand 10 gehalten wird. Der zwischen den Markisenarmen 20, 21 und der Gebäudewand 10 eingeschlossene spitze Winkel vergrößert sich zunehmend, bis er, wie in Figur 3 dargestellt, schlussendlich (fast) einen rechten Winkel erreicht. Vorzugsweise sind die Rollenanordnungen 26, 27 der beiden Markisenarme 20, 21 etwas gegen den jeweiligen Arm versetzt. Mit anderen Worten, die Stege 31, die die Rollenanordnungen 26, 27 tragen, sind voneinander weg abgewinkelt, um ein ungehindertes ein und Ausfahren der Markise zu gestatten, ohne dass die Markisenarme 20, 21 an der Fallschiene 19 anstoßen.

The awning 11 and the sunshade 12 described so far work as follows:

• The awning 11 is shown in the schematic representation FIG. 5 shown in undressed position. To extend it, the winding shaft 17 is driven so that the awning fabric 15 is unwound. As FIG. 3 shows, while pivoting the awning arms 20, 21 under the action of their respective spring 55 of the building wall 10 away. The roller assemblies 26, 27 move away from one another in the drop rail 19, the drop rail 19 being held parallel to the building wall 10 by the awning cloth 15 and the awning arms 20, 21. The trapped between the awning arms 20, 21 and the building wall 10 acute angle increases increasingly, until he, as in FIG. 3 shown, finally reached (almost) a right angle. Preferably, the roller assemblies 26, 27 of the two awning arms 20, 21 are slightly offset from the respective arm. In other words, the webs 31 which carry the roller assemblies 26, 27 are angled away from each other to allow unhindered entry and exit of the awning without the awning arms 20, 21 abutting the drop rail 19.

During the extension of the awning, the force exerted by the awning arms 20, 21 on the drop rail 19 away from the building wall 10 force increases despite decreasing spring force due to the change in angle of the angle between the awning arms and the drop rail or remains at least constant.

When the awning arms 20, 21 of the building wall 10th are stretched away, the awning 1 is extended. This condition is in the Figures 1 and 2 illustrated. It can now be activated, for example, the additional lateral sunshade 12. For this, see under References FIG. 8 first brought the cassette 43 in horizontal position. It is sufficient to pull the cartridge 12 at its building end down. A built-in cassette 43 spirit level can facilitate the horizontal adjustment of the cassette 12. Once the horizontal position has been reached, the blind placed in the cassette 43, for example a blind or the like, can be extended.

If necessary, the awning can be retracted at any time. If the lateral sunshade 12 is still in the pull-out position, it does not hinder the retraction of the awning. Thus, for example, a motor-operated awning can be retracted automatically at any time, without causing damage or danger.

On the other hand, it is possible by the winding device 52 to find a particularly secure stowed position. First, the curtain, for example, the blind, wound on the winding shaft 44. The sunscreen of the sunscreen 12 is thus completely absorbed by the cartridge 43 as possible. For further retraction, the trigger button 54 is actuated. Thus, the reel spool 53 is released and the right end 46 of the cassette 43 is pulled upward until it abuts against the awning arm 20 or 22. The awning 10 can now be retracted by winding up the awning fabric 15 as described above.

It is also possible to retract only the awning 11 and then the sunshade 12 by pressing the lock 54th to adjust to its upper position. Evidently, therefore, an awning 11 and a sunshade 12 are created in which incorrect operation is largely excluded. The structure is not only constructive, but also robust in terms of its operation.

The awning according to the invention has two awning arms, which are held on the drop rail in linear guides. In addition, a sunshade 12, 13, 14 is provided, the cartridge housing is held only at its two ends 45, 46 by suitable fastening means. Preferably, at least one of the two ends about a horizontal axis (web 37) is pivotally supported, while the other end 46 can be adjusted by a height-adjustable suspension 49 up or down.

The operation is very easy and safe.
