Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The invention relates to an articulated-arm awning having a bracket and a mounting tube/hollow section which can be attached thereto and is intended for holding at least one bearing block for at least one articulated arm and means for mounting a fabric shaft. 
     2. Relevant Prior Art 
     Articulated-arm awnings which can be attached to wall brackets by means of fitting sections or holders are sufficiently well known. Thus, for example, DE 25 14 941 C3 describes an articulated-arm awning having a cantilever awning box which is attached to wall brackets via wall holders. 
     However, attempts have long been made to combine as many parts of the articulated-arm awning as possible into a unit. 
     Thus, for example, DE 37 08 155 C2 describes an articulated-arm awning having a central fixing section which serves for holding the bearings for the articulated arms and for holding all adjusting mechanisms. 
     On the other hand, the attachment of articulated-arm awnings to buildings still involves a considerable amount of work. 
     SUMMARY OF THE INVENTION 
     It is the object of the invention to combine these two requirements, i.e. to provide a mounting device which both facilitates the attachment of the articulated-arm awning and permits the combination of the adjusting mechamisms and their attachment to a component. 
     It must not be forgotten that the entire construction must be stable and nondeformable and should nevertheless preferably consist of only a few parts. 
     This object of the invention is achieved if the mounting tube/hollow section has, above a first, preferably closed chamber, a second chamber for holding an adjusting mechanism, a continuous stepped hole for receiving a retaining bolt for the attachment of the bearing block is provided on the back of said mounting tube/hollow section, if furthermore the mounting tube/hollow section has at least one approximately hook-like mounting device on its back, and the bracket has at least one complementary hook-like mounting device.

     The invention is now illustrated in detail with reference to embodiments in conjunction with the attached drawings. 
     In the drawings,

     FIG. 2 shows a somewhat simplified embodiment of the mounting device. 
    
    
     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
     FIG. 1 shows a first embodiment of the novel mounting device for articulated-arm awnings. It consists of a bracket 1 which can be attached, for example, to the wall and to which a mounting tube/hollow section 2 is attached. 
     Mounting tubes and hollow sections are sufficiently well known per se. Here, however, a combination of the two conventional components is employed, serving both for attachment to the bracket and for attachment of other components of an articulated-arm awning. 
     Thus, it is possible to recognize, for example, a bearing block 3, to which an articulated arm (not shown) could be attached. Attachment means 4 are also indicated, on which further parts of an articulated-arm awning, such as, for example, the component indicated merely as the lower end of a housing 5, are to be seen. These parts are of conventional design and therefore require no further explanation in connection with the present invention. 
     Firstly, the mounting tube/hollow section 2 has a large chamber 6 which is located approximately in the center and into which stiffening ribs 6a and 6b can be drawn to provide rigidity. Further stiffening ribs may also be provided if thought to be necessary. 
     A round chamber 7 for a joint mechanism or tilting mechanism is provided above the chamber 6. This chamber 7 is open in front and serves for mounting a threaded bolt 8 which can be connected, for example, to a tilting mechanism. Constructions of this type are likewise generally customary and require no further explanation here. 
     The mounting tube/hollow section 2 has, at its lower end, a horizontal, forward-projecting strip 9 which has a narrow web 10 which points vertically upward and whose significance is still to be explained. In addition, the mounting tube/hollow section 2 has, below the chamber 6, a stepped hole 11 into which a retaining bolt for the bearing block can be inserted. 
     Furthermore, a chamber which widens from the outside inward is provided in the upper region on the back of the mounting tube/hollow section. This chamber 13 preferably has a T-shaped cross-section. A hook 14, preferably a hook-like strip 14 which can be pushed into this chamber, is inserted into the chamber. This hook-like strip 14 is bent downward. 
     Similarly, a chamber 15 of this type which widens from the outside inward and preferably has a T-shaped cross-section is arranged in the bracket 1, and a hook 16, preferably a hook-like strip 16, can be pushed into said chamber 15. These two hook-like strips 14 and 16 thus have, on their back, a cross-section corresponding to the cross-section of the chamber 13 or 15 and, on their front, in each case the corresponding hook-like strip 14 or 16. 
     Furthermore, grooves 17 and 18 which have an approximately T-shaped cross-section and into which the threaded nuts 19 and 20 can be inserted are provided at the bottom of the bracket 1 or of the mounting tube/hollow section 2. A retaining strip 21 which preferably has stepped holes provided with an internal thread for receiving retaining bolts 22 and 23 is provided for attaching the two parts to one another. 
     In this context, it should be mentioned that the bearing block has, in its lower surface, a narrow slot 24 into which the web 10 serving for attachment exactly fits. Moreover, the bearing block 3 contains, on its back, a T-shaped groove 25 which may be open continuously or only on one side and into which a threaded nut 26 can be inserted, into which nut the retaining bolt 12 can then be screwed for fixing the bearing block. 
     Finally, two retaining bolts 28 and 29 which serve for attaching the articulated-arm awning to the wall are also indicated on the bracket 1. 
     A few fundamentals must be stated in this connection since the novel mounting device for articulated-arm awnings is shown in principle only in a sectional view. It is clear that, depending on the length of the awning, one or more brackets 1 can be used. It is also clear that the brackets themselves may be of any width. 
     Similarly, one or more mounting tube/hollow sections will of course be used. This means that the retaining strip 21, too, can extend over the length of a bracket and of a mounting tube/hollow section, and that it can also extend over the total length of a plurality of brackets and a plurality of mounting tube/hollow sections. Accordingly, a required number of retaining bolts 22 and 23 will be provided. Where more than one articulated arm is provided, a corresponding number of bearing blocks is also provided. This also applies to the tilting mechanism, which is indicated here only by the threaded bolt. 
     On the other hand, it is also possible for the bracket 1 and the retaining strip 21 to consist of one piece. This would then dispense with the T-shaped groove 17, the nut 19 and the retaining bolt 22. 
     Finally, the mounting tube/hollow section has, on its back, also a further chamber 30 having a preferably T-shaped cross-section, into which it would then be possible to insert a hook-like strip 14 having a hook strip angled upward. The hook-like strip 16 would then have to possess a hook strip angled downward. 
     FIG. 2 shows a further embodiment of the novel mounting device for articulated-am awnings, in which identical parts are provided with the same reference symbols, so that the explanation given in connection with FIG. 1 essentially also applies to FIG. 2. 
     Instead of the chambers 13 and 15 and the hook-like strips 14 and 15, only hook-like strips are now provided. The bracket 1 has, on its front, an upward-pointing hook-like strip 31, while the mounting tube/hollow section 2 has, on its back, a complementary hook-like strip 32 which is angled downward and can be hooked into the hook-like strip 31. 
     The mounting device is now mounted as follows: First, the hook-like strips 14 and 16 are inserted into the grooves 13 and 15 of the mounting tube/hollow section 2 or of the bracket 1, and the mounting tube/hollow section 2 is suspended thereon. Thereafter, the retaining strip 21 is mounted from below with its retaining bolts 22 and 23, and these bolts are screwed into the nuts 18 and 19 and are tightened so that the two hook-like strips 14 and 16 fit tightly together. The cross-section of the hook-like strips can preferably be chosen so that a clamping effect is achieved. 
     The attachment of the bearing block or of the bearing blocks, which of course must be performed before attaching the mounting tube/hollow section 2 to the bracket 1, is in principle clear from the drawing. The bearing block 3 is mounted with its slot 24 on the web 10, after which the nut 26 is pushed into the T-shaped groove 25 and the retaining bolt 12 is screwed into the nut 26 and is tightened. The bearing block 3 then fits firmly on the mounting tube/hollow section and cannot move. 
     The information given for the mounting of the mounting device according to FIG. 1 applies in general terms also to the mounting device according to FIG. 2, the mounting here being substantially simpler since the mounting tube/hollow section 2 need merely be hooked with its hook-like strip 32 into the corresponding hook-like strip 31 of the bracket 1. The further procedure corresponds to the description given in connection with FIG. 1. 
     The actual articulated-arm awning, for example a cassette awning or an articulated-arm awning having only one articulated arm, can now be attached to the mounting device mounted in this manner. 
     Owing to this mounting device being oriented essentially in a vertical direction, an awning which is relatively flat in the horizontal direction is obtained, this being a particular advantage in many cases. 
     The invention thus provides a mounting device for an articulated-arm awning, which device is particularly suitable owing to its construction. The mounting tube/hollow section and the bearing block or the bearing blocks as well as the hook-like strips inserted into chambers having T-shaped cross-sections can be delivered in preassembled form. Furthermore, both the stepped hole 11 and the holes for the retaining bolts 22 and 23 in the retaining strip 21 can be provided with at least partial internal threads so that the retaining bolts can be screwed in to such an extent that they no longer fall out. In practice, the mounting tube/hollow section can thus be simply suspended and screwed on at the place of mounting. The object of the invention is thus achieved.
