Description

The invention relates according to the preamble of claim 1, a sunshade system with a roller tube on which a curtain is wound, wherein the roller shaft is supported on side brackets and a drive motor which drives the roller shaft is supported on a first bracket and in an inner cavity the cloth shaft protrudes, wherein an electrical equipment for controlling the drive motor and optionally controlling further electrical components is provided.

Such sun protection systems are widely used, especially in the design as awnings, with the arrangement of arranged in the roller shaft drive motors, which are also referred to as tubular motors, has prevailed.

The electrical controls for the motors, plugs and other electrical components, such as radio receivers are stowed in the other existing components of the system, such as in a cassette housing, a static support tube or in the side brackets under side covers. In any case, the space requirements of the electrical equipment is to be considered, which also forces to make adjustments, ie the outer dimensions of the system increase, which is usually considered to be a disadvantage. It also happens that the electrical equipment can not be integrated, so that at one point of the system a corresponding housing is additionally provided, which is visible and must also be laboriously sealed. Possibly. Also, other electrical control elements must be installed, for example, for controlling lighting devices, heating elements or speakers and the corresponding plug-in couplings for their contacting.

The object of the invention is to improve a sunshade system of the type mentioned in that the integration of the electrical equipment without changing the outer dimensions of the system is possible.

Main features of the invention are specified in the characterizing part of claim 1. Embodiments are the subject of claims 2 to 10.

According to the invention, it is provided that the electrical equipment for controlling the drive motor and / or for controlling further electrical consumers is fixed to the second console and projects into the cavity of the cloth shaft. The integration of drive motor independent electrical drive elements, such as. Dimmers, transformers or amplifiers may be made in view of the fact that other electrical devices may be provided on the sunshade system, e.g. Lighting equipment, radiant heaters or speakers. This is particularly advantageous because they sometimes even have their own housing, which made the integration into the investment particularly cumbersome.

The first console here is the console on the drive side and the second console the console on the drive opposite side.

It has been shown that with this measure, all required components can be concealed in the inner cavity of the roller tube can be arranged. It has been found that the fact that the roller tube rotates relative to the electrical equipment, which is not the case in the region of the drive motor, causing no disadvantages, of course, it should be noted that the relatively rotating parts after the Do not touch the assembly.

The storage of the roller tube can be done on the side of the drive motor in various ways, namely the fact that the roller tube is rotatably mounted on the side of the second console on this and on the side of the first console firstly directly to this or secondly to the housing of the drive motor is rotatably mounted.

The innovation according to the invention further provides the possibility of the preferred development of the invention to the effect that the cloth shaft is rotatably mounted on the side of the second console on a supporting structure surrounding the electrical equipment. Thus, it is also possible on the side of the electrical equipment to free the console of the function of direct storage for the fabric shaft, so that it can be made structurally simple and possibly space-saving. The bearing also continues to move inwards, which can help to reduce the deflection of the canvas shaft.

In particular, if sufficient protection for the electrical equipment can not be achieved by the lateral console and the cloth shaft surrounding the electrical equipment, it may be expedient that the support structure is formed as a housing in which the electrical equipment is accommodated.

In another, adapted to a sunshade system with a counter drive or a push / pull drive of the Ausfahrprofils embodiment is provided that the housing of the support structure is surrounded by a drive shaft, which at both ends of the cloth shaft gears for the Gegenzugsystem or push / pull system having. The drive shaft may be rotationally rigidly connected to the roller tube, which is usually the case in a push / pull system, in which the gears preferably engage in kink-stably guided, perforated steel bands which are connected to the case profile, or elastically rotatable to the roller tube be designed to provide a length compensation within the Gegenzugsystems.

In a particularly preferred embodiment of the invention it is provided that the support structure has at least one sliding ring, which is rotatable relative to the support structure. On the one hand, this sliding ring ensures a defined separation of the rotating and non-rotating parts of the sunshade system by slidingly sliding on the support structure. Thus, the support structure is effectively separated from the rotating canvas shaft or a drive shaft disposed between the canvas shaft and the support structure.

As an additional function, it makes sense to carry out the already mentioned storage of the roller tube in the radial and / or axial direction by the sliding member. So it is expedient with a suitable construction of the sunshade that the roller shaft is mounted on the at least one slide ring at the console end facing the support structure and / or that the slide ring for axially sliding support of the roller tube or the drive shaft on the console or with the Console connected, fixed part serves.

In a still further preferred embodiment of the invention it is provided that the support structure in each case has a sliding ring in the region of its ends.

This embodiment provides an additional support point displaced towards the center of the installation, which can be helpful in stiffening the canvas shaft against bending. Since two corresponding bearing points can also be formed on the drive motor designed as a tube motor, it is possible to support the roller tube or even a drive shaft arranged in the roller shaft at four points along its length.

In a further embodiment of the invention it is provided that the housing of the support structure is formed as a shaft housing, which is designed as a drive shaft extending to the drive motor, which is rotationally rigidly coupled to the fabric shaft. In such a solution, the shaft housing is supported only for axial securing on the side console, while the storage of the fabric shaft is done as usual via a gear and the console.

To build a self-supporting sunshade system, it is particularly preferred in a conventional manner that the consoles are connected to each other via a support member. Special embodiments may provide that the support member is designed as a plant housing or as a support tube. Under plant enclosures are here all flat housing elements between the consoles understood, including the case closed retractable cassette housing of cassette awnings.

In a further preferred embodiment of the invention it is provided that the wiring between the electrical equipment and the drive motor is guided along by the support member or on the support member. The cable management depends primarily on the structural conditions of the awning, the objective is to lay the cables as inconspicuous as possible, protected and easy to install.

Alternatively, it can also be provided that the wiring between the electrical equipment and the drive motor is guided through the fabric shaft, it being important to ensure that the cables can not come into contact with moving parts, so that this type of installation is considered more complex ,

Of course, it is also readily possible that a plug coupling for the on-site connection is integrated into the electrical equipment, so that this electrical component does not have to be otherwise attached to the sunshade system.

In Fig. 1 For example, a portion of a housing 10 is shown for receiving an electrical equipment 12 (see Fig. 2 ) suitable is. The housing 10 is tubular, wherein, the tube body 14 at least to the outside (console side) has an opening 16 through which the electrical equipment, which is housed here in a square plastic body, can be inserted into the housing. This can be done before assembly of the housing 10 in a canvas shaft 120, 220 of an awning 100, 200 or later, when a lateral bracket 122, 222 (see 3 and 4 ) has a sufficiently large implementation. This may also be advantageous for reasons of revision.

The housing 10 is formed with an annular flange 24 which is bolted to the lateral bracket 122, 222. Further, on the outer circumference of the housing, a sliding ring 26 between rotatably mounted to the annular flange 24 and the tubular body 14, which has a radial collar 28 towards the annular flange 24, which serves as a thrust bearing on the annular flange 24, when corresponding axial forces act. The slip ring further includes a radial projection 30 which is engaged in an axial groove (not shown) in the cloth shaft 120 or a drive shaft 140 in the assembled state. The annular flange 24 and the tubular body 14 are designed as separate parts, wherein the annular flange can be inserted with a cylindrical projection 32 in the inner diameter of the tubular body and axially secured by a bore 34 in the tubular body 14 by means of a pin or a screw.

Fig. 3 shows in longitudinal section an awning 100, which is designed as articulated arm awning, wherein the articulated arms are not shown for simplicity. Between side brackets 122, 123, the already mentioned cloth shaft 120 is rotatably mounted. On the fabric shaft 120, a flexible curtain (not shown) can be wound, the free end is attached to an extendable fall profile 102. On a first of the two consoles, an electric drive motor 142 is mounted, while on the second bracket 122, which is shown here in the direction of the illustration on the right side of the drawing, the housing 10 is screwed tightly with its annular flange 14. In the area of the second console 122, the housing 10 is shown broken, wherein Fig. 5 shows an enlarged detail view. Good to see the cylindrical projection 32 of the annular flange 24, on the outer circumference of the sliding ring 26 is freely rotatably mounted with its voltage applied to the annular flange 28 radial collar. The fabric shaft 120 is not directly connected to the sliding ring 26 but via a radially intermediate ring adapter 144 which is inserted into the green body 14, wherein an annular bead 146 limits the insertion. At the end of the housing lying further inside the cloth shaft, a further sliding ring 148 is fixed in a structurally identical design, in principle, by means of a further ring adapter 150, which can be secured axially in the housing 10 via a further radial bore 152. The electrical equipment 12 is inserted through the opening 16 in the annular flange 24 and may be supported with its quadrangular cross section as needed in a then adapted inner cross section of the cylindrical projection 32.

At the in Fig. 3 Shown embodiment, the canvas shaft 120 is thus axially and radially mounted on the slide ring 26, so that all forces of the roller tube are removed accordingly on the housing 10 with its annular flange 24. The inner seal ring 148 forms a further radial bearing point for the fabric shaft 120th

On the opposite side in the region of the first bracket 123 with the electric drive motor 142 supported thereon, the roller shaft is supported via two slide rings 154, 156 on the drive motor, namely a slide ring 154 located outside near the first bracket 123 and a further inside, at the inside end the engine lying inner slide ring 156th

The second console 122 on the side of the electrical equipment has a sufficiently large opening, so that the electrical equipment can also be placed or removed later after the removal of a panel in the fabric shaft, so that repair measures can be performed more easily. The electrical equipment 12 takes over the control of the engine, whereby a plug coupling for connection to the power grid can be integrated. The electrical equipment can also control other electrical loads, the corresponding switching signals can be processed via a control cable or via an integrated radio remote control.

The wiring between the electric equipment 12 and the drive motor 142 can be made through the cloth shaft 120, but because of the complicated assembly and the problem that the wiring may not come into contact with the rotating cloth shaft, the wiring is preferably made by a static member between the two consoles, such as passed through an awning housing or a support tube, which are not shown in the drawing or hidden by the winding shaft.

In Fig. 4 and 6 a further embodiment of a sunshade system according to the invention is shown, which is designed here as awning 200 with a Gegenzugantrieb, of which but only the electric drive motor 242, extending over the length of the canvas shaft 220 drive shaft 243 and two provided at the ends of the drive shaft 243 gears 245 are shown for driving a timing belt, not shown, or a chain. In these awnings, a length compensation is required because of the changing cloth shaft diameter in the winding of the curtain, which can be provided by the fact that the drive shaft 243 is rotatable relative to the fabric shaft 220 against the force of a torsion spring. However, this is essentially based on known prior art and will not be discussed in detail here. However, there are changes compared to the previously discussed embodiment according to Fig. 3 and 5 Changes in the area of the housing 10, which are presented below.

The structurally identical housing 10 with the electrical equipment 12 received therein in turn has an annular flange 24 and a rotatably mounted between this and the tubular body 14 sliding ring 26. At this slide ring 26 but not the fabric shaft 220 is stored here, but the drive shaft 243, wherein the drive shaft 243 forms a composite with the cloth shaft 220, so that no weight forces of the cloth or drive shaft must be supported here via the slide ring 26. Any axial forces that may occur, however, can be removed via the radial collar 28 to the annular flange 24.

The already mentioned gears 245 at the ends of the drive shaft 243 also serve for the direct storage of the cloth shaft 222 at a bearing point of the second bracket 222. They are positively interlocked in the direction of rotation with the drive shaft. Again, a second seal ring 248 is provided which engages the drive shaft in the direction of rotation and corresponding to the drive shaft 243 is rotatable relative to the housing.

In the area of the first bracket 223 (on the left side in the sense of illustration), an electric drive motor designed as a tubular motor is again provided, on the housing of which the drive shaft 243 is supported by two sliding rings 254, 256.

Also at the in Fig. 4 shown awning 200 with counter drive, it is advantageous if the second bracket 222 has an optionally hidden by a removable aperture opening through which the electrical equipment 12 can be spent in the housing in its assembled state. Incidentally, for the electrical equipment and its wiring to the drive motor in this embodiment, the same Abwandlungsmöglichkeiten apply as in the previously described embodiment without counter drive.

The invention is not limited to one of the above-described embodiments, but can be modified in many ways.

All of the claims, the description and the drawings resulting features and advantages, including design details, spatial arrangements and method steps may be essential to the invention both in itself and in various combinations.
