Provision can also be made for housing sensors which, for instance, control the required degree of extension of the blind or have a protective function (monitoring wind loading). Suitable terminations are provided for connection to the domestic power supply.

Description

The invention relates to a sun protection system a sun protection curtain with at least one electrical Drive that controls the setting of the Sun protection curtain depending on several input variables automatically performs, at least one sensor for detection the wind load acting on the sun protection system as Input variable provided for the control and the control wired ready for use integrated in the sun protection system are and a supply connection preferably for connection is provided with a common household electricity network.

So far, solutions have been common in which the control and sensors for recording the input variables externally, separately are arranged by the sun protection system. This arrangement, where the central sensors are often on the roof a building are arranged and a central control for all sun protection systems is provided, requires a number of disadvantages. The external arrangement of the sensors leads due to the spatial distance from the sun protection system to Some significant deviations of the measured critical environmental influences, such as B. Wind, compared to the actual load the sun protection system. These hard-to-predict deviations must be offset by collateral in the tax program that are essential for wind monitoring cause the sun protection to be retracted earlier than it from the actual actual load on the sun protection system seen would be necessary.

The external arrangement of the control in turn requires one considerable wiring effort, being next to the more difficult Connection of the individual sun protection systems, especially the building side Laying the control and supply lines involves considerable effort.

Depending on the type of installation, the housings of the controls or the Sensors and their electrical connection lines to the Sun protection system also the visual impression for the viewer to disturb.

A sun protection system is already known from DE 44 07 342 A1 with an integrated control and an integrated wind load sensor known. The detection of wind-excited forces in the area of the motor or a bracket does not always lead to satisfactory results.

The object of the present invention is a Create sun protection system with an integrated Wind load sensor enables reliable detection of the wind load.

According to the invention, the task is performed by a sun protection system solved according to claim 1.

Such a sun protection system, its operation, for example can be done with the help of a radio remote control Receiver is also integrated into the system, only has to mounted in the area of the window opening to be shaded and connected to the household electricity network. The electric one Wiring is minimal because it only has to a connection to the nearest distribution point of the Electricity network are produced. The one with external controls necessary configurations after interconnection also eliminated.

It is also advantageous that a sensor for detection of the input variables wired ready for operation into the sun protection system integrated and also a supply connection preferably for connection to a common household electricity network is provided.

Another significant advantage of integrated sensors for Detection of the wind load consists of the input variable is detected directly in the area of the sun protection system and thereby guarantees in the sense of an optimal automatic Control can be reduced to a minimum, with the achieved particular advantage of the solution according to the invention is that the wind load sensor in the form of a vibration or Accelerometer in one of the attacking wind arranged particularly strongly excited area of the sun protection system is. With articulated arm awnings, these areas are in close to the drop profile and the articulated arms, one Arrangement of the wind load sensor on or in the articulated arm in the Proximity of the drop profile or the central joint is particularly preferred is.

The control is preferably in a housing of the sun protection system installed or in a separate control housing provided that on or in parts of the sun protection system is attached.

Depending on the nature of the sun protection system, this has already have a housing that can accommodate the circumstances sensitive to moisture and dust, for example Control is suitable. In other cases it is expedient to provide the controller with a housing that on the one hand offers the required protection for the control and easily integrate into the sun protection system leaves.

With an articulated arm awning, which may not have a housing at all has but only has open frame parts, is the controller preferably integrated into the support tube. in this connection it is conceivable to control directly in the support tube to assemble and seal the ends in a suitable manner or the control with a separate control housing in insert the support tube. A slot in the support tube or one special sealing cap enables lateral execution the connecting cables to the sensors, the drive and the Power supply network. With such an integrated control this disappears almost invisibly in the support tube.

If the installation in the support tube or in the support bracket is not possible, the housing can of course with suitable fasteners such. B. a clip connection, be attached to the support tube.

Should the sun protection system with the help of a remote control be adjustable, it is particularly useful to do this necessary antenna in an exposed wiring as additional Integrating vein.

1 shows the possible integration of a controller 10 in an articulated arm awning is shown, of which for illustration only a support tube designed as a square tube 12 and a support bracket 14 for mounting the awning on one Wall or a ceiling projection is shown. The control 10 is in the inner cross section of the support tube 12 arranged in cross section adapted control housing 16, which can be inserted laterally into the support tube 12. On the front of the housing are three connection options provided, with a first connection 18 for connection to one or more sensors, a second connection 20 for Connection with an electric drive for the folding arm awning and a third connector 22 for connection to one Power supply network, for example a household power network, is provided. A side slot 24 allows the lateral execution of those connected to the controller 10 Connection lines to the sensor, the drive and the power supply.

In Fig. 2, the support tube 12 is after placing a side Cloth shaft bracket 26 with a side plastic cover 28 shown. The bracket 30 of an articulated arm (see Fig. 4 and 5) is attached to the support tube 12 and screwed (Screws not shown). After touchdown the cloth shaft bracket 26 and the plastic cap 28 is that Housing 16 invisibly hidden inside the support tube 12. Only the connecting cables of the Controller 10, with a sensor line 32 on the support tube 12 is guided along to the articulated arm 30. A drive line 34 leads to that in the cloth shaft (not shown) which in the Cloth shaft console 26 can be used, arranged electrical Drive motor (also not shown). A supply line 36 will be sent to the nearest distributor connected to the household electricity network. Because the sensor that Drive and control are already wired ready for operation and configured, the articulated arm awning can be Assembly and connecting the supply line 36 with the Household electricity network can be put into operation immediately.

In Fig. 3 is an alternative placement of a controller 110 shown on a support tube 112 of an articulated arm awning, in which the housing 116 of the controller 110 is limited Space cannot be installed. There are therefore mounting brackets 124 provided the support tube Wrap 112 and in grooves provided in the housing 116 125 intervene. At the front of the controller 110 are again Connections 118, 120, 122 for the electrical lines intended. A support tube bracket 114 and a cloth shaft bracket 126 are also shown. The controller leading electrical cables can be used in the usual way Help of known fastening aids from the field of electrical installation, z. B. with the help of self-adhesive cable tie loops, be made.

In Fig. 4, an articulated arm half 38 is shown with Using a drop joint 40 on a drop profile (not shown) and via a central joint (not shown) on one upper articulated arm is pivotally fixed, the upper articulated arm halves with the articulated arm holder 30 (see FIG. 2) is articulated. Near the joint 40 is a Vibration sensor 42 is provided which through a bore 44 in Profile of the lower articulated arm half 38 into the articulated arm interior can be introduced. The sensor 42 is via the connecting line 32 (see also Fig. 2), which leads past the articulated arm profiles on the outside is connected to the controller 10. A cover strip 46 protects the connecting line 32 and the sensor 42 Damage, the cover strip 46 on its long sides has locking lugs 48 which in corresponding grooves 50 engage in the longitudinal direction on the articulated arm half 38 are provided. The location of the sensor 42 nearby the failure profile has proven to be advantageous because in particularly strong vibrations and accelerations in this area can occur under the influence of wind load.

With articulated arm awnings, where the installation inside the Arm profile is not possible, an installation situation according to 5 may be provided. Here is a wind load sensor Vibration sensor 142 protected by a plastic receptacle 144 near the articulated arm center joint 146 on the upper articulated arm half 148 attached. It's another one Cover bar 150 is provided, which is not shown in FIG. 5 Connection line to the controller 10 covers. The Sensor 142 is installed in plastic receptacle 144 indented and the latter is with retaining tabs 152 in grooves 154 engaged on the upper half of the articulated arm 148, in which the cover strip 150 is also attached. The advantage of this Arrangement is that with the connecting line to Control only one joint must be bridged, too the sensor position due to the pronounced movement of the middle joint Also particularly suitable in the event of a wind attack on the cloth is.

Of course, other positions of the vibration or acceleration sensor conceivable, for example also on the drop profile of the folding arm awning, being as Disadvantage, however, is the routing of the connecting line a total of three joints to control is to be mentioned. Other sensors that influence the control 10 Take a curtain, for example rain, light or Temperature sensors can also be used on a suitable exposed point of the articulated arm awning.

A wire is also preferably in the connecting line 32 integrated as a receiving antenna for a radio remote control the sun protection system can be used.

Basically, it is also with other types of sun protection systems, such as B. with venetian blinds or drop arm awnings, conceivable, Integrate sensors and control in a form that that described above using the example of an articulated arm awning The arrangement is similar, but the respective peculiarities are adjusted.
