Description

The invention relates to a roller blind roller blind with a curtain of a plurality of horizontally arranged and non-interlocking rods, the rods having end-mounted guide elements at their ends and are connected thereto via a pivot axis in the lower region of the rods, wherein the guide elements in vertical guide profiles are guided and have actuators that allow pivotal movement of the individual rods.

The idea of providing shutters with bars that can be swiveled around a horizontal axis for opening purposes has long been known. For this purpose various technical solutions have been presented ( DE 29 29 675 A1 . EP 0 056 650 B1 ).

Systems are known which trigger the pivoting of the roller shutter bars with a rail system ( DE 94 03 992 U1 ). The rods are attached to the rail and this rail can be driven up and down by a toothed belt principle, whereby the rods are each brought into a closed or open position. Another mechanical adjustment of a jalousable shutter is from the DE 198 42 502 A1 known. In addition, solutions with pull bands acting on the bars are also known (US Pat. DE 20 2013 100 148 U1 ). All these solutions are structurally very expensive.

In many developments, an individual adjustment is not possible. Often there is only the variation between open and closed or even open ( DE 10 2005 037 775 B4 ). So there is only one position where the light is directed. There is no known development in which the adjustment of the fins for light steering is possible in any position of the tank.

The current market situation calls for a way to make better use of the sun's rays and thus of solar energy. However, it must not be waived on the known advantages of the shutter, for example, in the night hours.

On this basis, the present invention seeks to design an above-described and previously explained in more detail Venetian blinds and further develop to achieve with little effort and without Übertechnisierung optimized swinging and so to create a louverable and "light-directing" shutters.

This object has been achieved in a roller shutter according to the preamble of claim 1, characterized in that as actuators first magnets are provided, which are arranged outside of the roller shutter other magnets by suitable tightening and / or repelling to open and possibly closing the rods movable. In the guide elements are two magnets that tighten, or repel each other by opposite polarity magnets. As a result, the roller shutter is pivoted in the desired area in the light-conducting opening position. The angle of incidence is about 60 °. The advantages of the invention are that the rods pivot from below, so the rod can guide the light indirectly into the space through the rod shape.

Whenever "magnets" are mentioned, in particular also magnet coils or magnet coil modules, ie electromagnets, should be included, which can be controlled centrally.

A further teaching of the invention provides that each guide element has a pivoting element connected to the associated rod end and a locking element located vertically in the guide profile. These elements, together with the guide profiles, which each lead a carriage on the right and left, form the core of the invention. Preferably, in a further embodiment of

Invention, the pivoting element locked in pivoted position with the locking element. This can be done for example by a known form-locking locking connection in the pivoting element and / or locking element. The guide elements are made of a plastic material components. In it are all mechanical components for a perfect function of the shutter blinds. The axis is most important for the pivoting of the shutter and must be stably and securely connected to the locking piece. It is preferred to use a reinforced axle, which is inserted deeper into the locking element and glued there or firmly connected in another way.

A further preferred embodiment of the invention provides that the opening angle between the pivot element and the locking element is variable. To vary the angle of the individual rods of the curtain, an adjustable stop element is provided on the pivoting element and / or on the locking element. Alternatively, however, it is also possible (and structurally simpler) if the opening angle between the pivot element and the locking element is fixed. Here, for example, has proven a value of 60 °.

In order for the rods pivoted into the open position to retain their position and not to swivel them again, for example by draft, another preferred teaching of the invention provides that each guide element has a spreading element for holding the pivoting element in its open position. This is preferably a spring which extends around the pivot axis and whose legs are fixedly connected to the pivoting element or the locking element. The springs at both ends of each rod thus ensure reliably that the curtain does not swivel back in the open position even under the influence of wind.

According to a further embodiment of the invention it is provided that the pivot axis passes through the locking element and at its end has a non-rotatably connected lever, which lies in pivoted position in the plane of the curtain. For pivoting is preferably at least one magnet in or arranged on the lever. Alternatively, it is also possible that the complete lever is designed as a magnet. By applying a magnetic force to the end of the lever, an "opening" of the respective rod takes place, which is then, preferably supported by the already described spring force, pivoted into its end position (open position).

For "closing" an open rod is used according to another teaching of the invention, at least a second magnet in the upper region of the pivot member.

For pivoting the rods are arranged according to a first embodiment of the invention, the further magnets for actuating the magnets on the pivoting or locking element on a movable carriage. Alternatively, it is also possible that the further magnets are formed by a plurality of electromagnets arranged in or on the guide profile, which can be activated or reversed by a suitable control for opening any bars or bar areas.

A structurally particularly elegant design is achieved when, instead of a slide or a plurality of magnets distributed in the guide profiles arranged in each case a magnet or solenoid module is arranged in the two inlet funnels. Such a design is quite sufficient to achieve the same effect: The fact that when extending the shutter all bars the inlet funnel and thus the magnets located there to open, can with an 'intelligent' control, which also saves space in one of Inlet funnel can be arranged, the information about the to be opened when descending rods to the two magnets are passed. The inlet funnel without control in this case only needs to have a module which executes the commands of the controller by means of the local magnet. Appropriately, the control unit is sealed in the inlet funnel, but can of course be installed elsewhere. The controller can also be expanded - possibly modulo attachable - other modules, such as radio modules for bidirectional communication.

In the embodiment by means of slides, each carriage each has a magnet for opening and a magnet for closing individual rods of the roller shutter. For actuation of the carriage within the guide profile is movable vertically, with repelling magnets exerts a force on the rotatably connected to the rod lever to overcome the locking force between the locking element and pivot member and so pivots the respective rod in its open position. A method of sliding in the opposite direction can be attracted by another magnet, the magnet at the upper end of the pivot member. In this case, the magnetic force must be greater than the spring force of the expansion element and the locking force between the locking element and the pivot element in order to achieve a reliable locking of both elements (at each end of the rod).

Since, unlike in 'conventional' shutters, adjacent bars are not hooked together, provide according to another teaching of the invention, two superimposed locking elements by means of a connecting element for a pivotal connection of two adjacent bars.

A further embodiment of the invention provides that each connecting element has a slot for releasing or closing the respectively immediately adjacent bars. If the curtain (with all the bars in closed position) has moved completely down, the upper webs of the bars reach into the pocket of the respectively overlying bar, so that the curtain is positively closed like a conventional roller shutter. When the bars are raised again, the oblong holes ensure that an air gap is created between the adjacent bars so that a reopening of individual bars or bar areas is possible.

Preferably, the guide elements are arranged completely within the guide profiles. In this way, the shutter according to the invention - looks from the inside and outside - like a conventional roller shutter.

In order to maintain the usual function of the shutter in a further embodiment of the invention, the curtain can be wound on a winding shaft. For winding the optionally still open rods are closed positively guided by suitable guide or actuating means when leaving the vertical guide profile, so that a normal roller shutter function is possible. The roller shutter armor can therefore also be moved (wound up) despite open bars. The rods adapt to the winding behavior. It is conceivable to drive the entire system with a drive unit or with two separate drives. Also, the roller shutter according to the invention is therefore a normal, winding roller shutter, in which nevertheless the rods can steer the light into the room by pivoting.

Theoretically, the mechanics apply to all rods. In most known solutions, various disadvantages arise, so most developments in the market work with extruded rods, which makes the end product unnecessarily expensive. Therefore, another teaching of the invention provides that the rods are roll formed. This means that existing material can be used during production, thus saving time. However, it is also conceivable that, alternatively, a special extruded roller shutter rod is used for this system. Retrofitting is also possible because existing bars can still be used after forming with a special tool.

According to the invention is a roller shutter whose bars directs the daylight into rooms. Conceivable is a highly reflective coating of the rods, so that the light is directed more effectively into the room. Thus, the roller shutter armor according to the invention is particularly suitable for rooms that achieved little or no natural light.

In the embodiment with carriage, the roller shutter in any position, whether half shut down or completely down, by the carriage, the individual pivotally mounted roller shutter bars pivot in an open or closed position. This results in a roller blind that can be opened, which is structurally simple and easy to install. The roller shutter can be mounted depending on the construction project as a left or right scooter. Due to the magnetism in the guide elements, the bars, no matter which position the curtain has to be brought into a closed or in an open position. The advantage of this is that you can use a "normal" shutter as it were, to darken a room or to fulfill the function of the light control to produce an indirect light.

In Fig. 1 an inventive curtain 1 a jalousable roller shutter is shown in perspective in the upper part of the curtain 1 partially swung rods 2. For a better understanding of the function of the vertical section along the line II - II is off Fig. 1 in Fig. 2a shown. There, the opened (upper) region of the curtain 1 is denoted by the reference symbol 1A and the closed (lower) region of the curtain 1 by the reference symbol 1B. It can be seen that the opening angle is about 60 °, so that the reflection of the daylight on the bars 2, an indirect illumination of the space behind it takes place.

In this case, the individual bars 2, as already known per se from the prior art, are each connected at their ends to guide elements 4 which are described in detail below, in each case in vertical guide profiles 4, via a respective pivot axis 3 in the lower region of the bars 2 are guided. Each guide element 4 has a pivoting element 6 connected to the respective end of the rod 2 and a locking element 7 located vertically in the guide profile 5, in particular the enlarged illustration in FIG Fig. 3 can be seen.

Fig. 2b shows an alternative embodiment. At first one recognizes, identically Fig. 2a , A winding shaft 15, by means of which the curtain 1 can be wound in a known manner in a roller shutter box 16. A mechanical guide roller 17 ensures a positively controlled closing of opened individual bars of the curtain when raising the shutter. Below the roller shutter box 16 is in Fig. 2b an inlet funnel 19 is shown, in which a magnetic module M3 is arranged such that its activation causes an opening of the passing roller shutter bar 2, as will be described in detail below. An only indicated control unit 20 ensures the corresponding implementation of the operating commands in a control of the magnets M3. Incidentally, the right Fig. 2b with the Fig. 2a match.

The function of "opening" individual bars or bar areas is best understood Fig. 4 represent. There shows Fig. 4a - For the embodiment with carriage - the end portion of the curtain 1 analogous to Fig. 3 in perspective view and the figures Fig. 4b and 4c in two side views, for better explanation of the interaction of the actuators all bars 2 are shown closed, even if in this position, the upper two bars 2 would have to be open.

Before discussing the interaction of all structural parts, the construction of a single guide element 4 based on the perspective view of the same in FIG Fig. 5 to be introduced. It can be seen first, the pivoting element 6, which is attached to the front end of the rod 2. The pivoting element 6 is arranged pivotably on the locking element 7 via the pivot axis 3, wherein a spring 8, of which only the free leg connected to the pivoting element 6 can be seen, is guided around the pivot axis 3 as a spiral spring. The other free leg of the spring 8 is (in Fig. 5 not visible) in a corresponding manner connected to the locking element 7. In this way, it is ensured that the curtain 1 does not swivel in the open position even under the influence of wind.

It can also be seen that the pivot axis 3 is guided through the locking element 7 and at its end a rotatably mounted lever 9 has. For magnetic drive serve two magnets M1 and M2, of which the first is arranged at the free upper end of the pivot member 6 and the second at the lower end of the lever 9. On a carriage 10, two more magnets M3 and M4 are attached, as shown in the Figures 3 and 4a evident. The carriage 10 is vertically displaceable by means of a guide 11 along a guide rail 12 arranged in the interior of the guide profile 5. The magnets M1 and M3 repel each other, so that when moving the carriage 10 down to open the with the Swivel elements 6 connected rods 2 takes place. On the other hand, if the carriage 10 moves upwards, the magnets M2 (in the lever 9) and M4 push off and the corresponding rod 2 is closed. As already mentioned, in the case of the Fig. 2b version without slide on the magnets M4 are omitted, since the closing of already opened bars 2 is positively guided during startup of the curtain 1.

The exact arrangement of the magnets M1 to M4 is best the Fig. 4a to 4c refer to. You can see clearly - as well as already Fig. 5 stated that the magnets M1 are embedded in the upper region of the pivoting element 6 and the magnets M2 are in the lower region of the lever 9. While the lower illustration in the Fig. 4a to 4c is reproduced correctly, at least the second rod 2 would have to be opened from above, since the magnets M1 and M3 are also repelled. In the position shown, however, the spatial proximity of these two magnets M1 and M3 can be seen very clearly, in this way a reliable opening of the respective bars 2 takes place.

In the Fig. 4a such as Fig. 5 is also clearly the articulated connection between the respective adjacent guide elements 4 to recognize. The purpose of a connecting element 13, which has a slot 14 at its upper end, to allow a longitudinal displacement of two adjacent bars 2. In Fig. 5 is shown above the guide member 4 shown in phantom, the connecting element 13 of the guide element (not shown) arranged above it. The bars 2 of the curtain 1 are thus, except for the mutual entanglement, as in "normal" blinds hinged together. Thus, the curtain 1 can be wound in a known manner on a winding shaft 15 in a roller shutter box 16, as in the Fig. 2a and 2b shown. A mechanical guide roller 17 ensures that the curtain 1 can be wound even in the "open" state by after exiting the vertical guide profile 5 by acting on the pivoted lever 9 a positively guided closing of the rods 2 takes place before they are wound up, so that a normal roller shutter function is possible.

To achieve the articulated connection, the connecting element 13 is rotatably arranged not only in the region of the pivot axis 3, in its lower region, the connecting element 13 has an axis 18 which engages in a corresponding recess of the locking element (not shown) arranged thereunder and with this is rotatably connected.
