DESCRIPTION

Roller blind body usable as mobile slatted blinds with pivoting bars

The invention relates to a roller blind body usable as a mobile slatted blind with a screen made from a plurality of horizontally arranged bars and not hooked together, the bars presenting at their ends gluttonic elements arranged on the front side and being joined with these through a pivot axis in the lower part of the bars, the glutton elements being guided by vertical glutton profiles and presenting drive elements, which allow a pivotal movement of the individual bars.

The idea of providing roller blinds with pivoting bars around a horizontal axis for opening purposes has long been known. For this, various technical solutions have been presented (DE 29 29 675 A1).

Systems are known which cause the pivoting of the roller blind bars with a rail system (DE 94 03 992 U1). The bars are fixed to the rail and this rail can be moved up and down by a toothed belt principle and due to which the bars are taken in each case to a closed or open position. Another installation of mechanical adjustment of a roller blind that can be used as a mobile slat blind is known from DE 198 42 502 A1. In addition, solutions with traction belts acting on the bars are also known (DE 20 2013 100 148 U1). WO 2012/065917 A1 describes a blind with rotary adjustable bars, which are adjusted in each case by means of a pinion drive of a toothed bar. All these constructions are constructively very laborious.

In the case of many of the developments, individual adjustment is not possible. Often there is only the variant between open and closed or even only open (DE 10 2005 037 775 B4). There is therefore only one position in which the light is directed. There is no known development in which it is possible to adjust the lamellae for the direction of the light in each position of the body.

A roller blind body according to the order with all the features of claim 1 is known from EP 0 056 650 B.

The current market situation demands a possibility to take better advantage of the incident sun rays and with it also the solar energy. In this case, however, the known advantages of the roller blind should not be waived, for example, at night.

Starting from this, the present invention is based on the objective of configuring and perfecting in such a way a roller blind usable as a mobile slat blind described initially and explained above in greater detail, to achieve with an effort reduced and without overtechnification, an opening optimized pivot and thus create a roller shutter that can be used as a blind for mobile slats and "light addressing".

This objective is achieved in the case of a roller blind that can be used as a mobile slat blind with all the features of claim 1, because first magnets are provided as actuating elements, which can be moved by additional magnets arranged outside the body roller shutter by attraction and / or repulsion suitable to open and eventually close the bars. In the gluttony elements there are two magnets, which are attracted, or repelled by magnets of opposite pole. Because of this, the roller shutter is pivoted in the desired area towards the light addressing position. The angle of incidence of light is in this case approximately 60 °. The advantages of the invention are that the bars pivot from below, in this way the bar, due to the shape of a bar, can direct light indirectly into space.

When talking about "magnets", in this case, particularly magnetic coils or modules of magnetic coils, ie electromagnets, which can be centrally controlled, must be included in this case.

The use of magnets is already known per se by DE 40 20 244 A1. There! the magnets serve, however, for the glutton of bar ends in the case of an oblique blind.

Another teaching of the invention provides that each glutton element has a pivoting element connected to the corresponding rod end and a stop element that is perpendicularly in the glutton profile. These elements form together with the gluttony profiles, which gula respectively to the right and to the left a carriage, the core of the invention. Advantageously in another configuration of the invention, the pivoting element is interlocked with the stop element in the pivoted position. This can occur, for example, by means of a positive connection hitch connection known per se in the pivoting element and / or stopping element. Gluttony elements are components manufactured from a plastic material. They contain all the mechanical components for the proper functioning of the roller blind that can be used as a mobile slatted blind. The axis is the most important for pivoting the roller blind and has to

be stably and securely attached to the stop piece. A reinforced shaft is preferably used, which is inserted deeper into the stop element and glued there! or fixedly connected in another way.

Another preferred configuration of the invention provides that the opening angle between the pivoting element and the stopping element is variable. For the variation of the angle of the individual bars of the screen, an adjustable stop element is provided in the pivoting element and / or in the stop element. Alternatively it is possible, however, also (and constructively simpler), when the opening angle between the pivoting element and the stopping element is predetermined in a fixed manner. In this case it has proved advantageous, for example, a value of 60 °.

In order that the bars pivoted to the open position maintain their position and do not pivot back - for example, due to air flow -, another preferred teaching of the invention provides that each glutton element has an extension element to hold the pivot element in Your open position. In this case it is preferably a spring, which extends around the pivot axis and whose arms are fixedly connected with the pivoting element or with the stopping element. The springs at both ends of each bar therefore reliably guarantee that the screen in the open position does not pivot back even in the event of the influence of the wind.

According to another configuration of the invention, it is provided that the pivot axis passes through the stop element and has at its end a lever connected in a rotatable manner, which in a pivoted position is located in the plane of the screen. For pivoting, at least one magnet is preferably arranged inside or on the lever. Alternatively, it is also possible that the entire lever is configured as a magnet. When applying a magnetic force on the end of the lever, an "opening" of the corresponding bar is produced, which is then pivoted, preferably with the help of the spring force already described, to its final position (open position) .

To "close" a bar in an open position, it is used according to another teaching of the invention, at least a second magnet in the upper area of the pivoting element.

To pivot the bars, the additional magnets in the pivoting or stopping element for the actuation of the magnets are arranged according to a first configuration according to the invention in a movable carriage. Alternatively, it is also possible for the additional magnets to be configured by a plurality of electromagnets disposed within or on the glutton profile, which can be activated or reversed in their polarity by means of a suitable control to open any bar or bar area.

A particularly elegant configuration as far as the construction is concerned is achieved when instead of a carriage or a plurality of magnets arranged in a distributed manner in the glutton profiles, a magnet or magnetic coil module is disposed in each case. The two input conductors. Such a configuration is completely sufficient to achieve the same effect. Because when unrolling the roller shutter, all the bars pass for the opening the entrance conductors and with it also the magnets there! present, with an "intelligent" control, which can also be arranged with space saving in one of the input conductors, the information on the bars to be opened during the descent can be transmitted to the two magnets. The input funnel without control only needs to present in this case a module, which carries out the control orders through the magnet all! Present. Advantageously, the control unit is fixedly cast in the inlet funnel, but it can also be mounted naturally elsewhere. The control can also be extended by other modules -eventually available in a modular way-, for example, radio modules for bidirectional communication.

In the case of car configuration, each car has in each case a magnet to open and a magnet to close individual bars of the roller shutter body. For actuation, the carriage can move vertically within the glutton profile, exerting magnets that repel a force on the lever connected in a manner resistant to rotation with the bar, to overcome the clamping force between the stop element and the pivoting element and thus swinging the bar corresponding to its open position. A displacement of the carriage in the opposite direction, allows to attract by means of an additional magnet, the magnet of the upper end of the pivoting element. In this case the magnetic force must be greater than the spring force of the extender element and the clamping force between the stop element and the pivoting element, to achieve a reliable stop of the two elements (at each end of the bar) .

Since, unlike the case of "conventional" roller blinds, the adjacent bars are not hooked together, according to another teaching of the invention, two stop elements arranged one above the other are occupied by a connecting element, of a pivoting connection. of two adjacent bars.

Another configuration of the invention provides that each connecting element has a longitudinal hole to release or close the bars in each case directly adjacent. If the screen (with all the bars in the closed position) has been completely lowered, the upper ribs of the bars are caught in the bag

of the bar arranged in each case above, so that the screen is closed in positive connection like a conventional roller blind. If the bars are now raised again, the longitudinal holes make sure that a small slit results between the adjacent bars, so that a new opening of individual bars or bar areas is possible.

Preferably the gluttony elements are arranged completely within the gluttony profiles. In this way the roller blind usable as a blind of mobile slats according to the invention has the appearance - from inside and outside - of a conventional roller blind.

To maintain the usual function of the roller blind, the screen can be wound on a winding tube in a further configuration of the invention. For the winding, the bars, possibly even in the open position, are closed in this case by means of gluttony or of suitable actuation when leaving the vertical glutton profile due to forced glutton, so that a normal rolling shutter function is possible. The roller blind body can be moved (rolled up) therefore also despite being open bars. The bars adapt to the winding behavior. It is conceivable to drive the entire system with a drive unit or with two separate drives. The roller blind according to the invention is therefore also a normal roller blind that is rolled, in which however, the bars can conduct light into the space by pivoting.

Theoretically, mechanics can be used on all bars. In the majority of the known solutions different disadvantages result, in this way most of the developments in the market work with extruded bars, due to which the final product becomes unnecessarily expensive. Because of this, an additional teaching of invention provides that the bars are shaped by profiling. In this way you can make use during the production of present material, and save time in this way. It is conceivable, however, that a special extruded roller shutter bar is used alternately for this system. Retrofitting is also possible, since existing bars can continue to be used after shaping with a special tool.

According to the invention it is a roller blind whose bars direct the daylight towards spaces. A strongly reflective coating of the bars is conceivable, so that light is directed even more effectively to the space. In this way the roller blind body according to the invention is particularly suitable for spaces, which are not reached or hardly are, by natural light.

In the configuration with trolleys, the roller blind can pivot by means of the carriage in each position, or halfway lowered or completely lowered, to an open position or to a closed position the individual roller blind bars housed pivotally. This results in a roller blind that can be used as a mobile slatted blind, which is constructively simple and easy to assemble. The roller blind can be mounted depending on the end of the construction, such as winding to the left or right. By means of the magnetism in the gluttony elements, the bars, whatever the position of the screen, can be taken to a closed or an open position. The advantage is in this case, that almost a "normal" roller blind can be used to obscure a space or to fulfill the function of the direction of the light for the production of an indirect light.

The invention is explained in more detail below by means of a drawing that represents only one example of a preferred embodiment. In the drawing they show

For a better understanding of the function, a function is shown the cross section along line II-II of Fig. 1 in Fig. 2. All! the open (upper) zone of the screen 1 is indicated with the reference 1A and the closed (lower) zone of the screen 1 with the reference 1B. It can be seen that the opening angle is approximately 60 °, so

that through the reflection of the daylight, an indirect illumination of the space behind is produced on the bars 2.

In this case, the individual bars 2, as is known per se of the state of the art, are connected through in each case a pivot axis 3 in the lower area of the bars 2 at their ends on the front side with glutton elements 4 which will be described below in greater detail, which are gouted by vertical glutton profiles 5. Each glutton element 4 has a pivoting element 6 connected to the corresponding end of the rod 2 and a stop element 7 that is perpendicularly in the gluttony profile, as can be seen particularly in the enlarged representation of Fig. 3.

Fig. 2b shows an alternative embodiment. In the first place, a winding tube 15 can be seen identically to Fig. 2a, with the aid of which the screen 1 can be wound in a known manner in the roller shutter box 16. A mechanical glula roller 17 is occupied in this case of a controlled forced closure of individual open bars of the screen when the roller blind is raised. Below the roller shutter box 16, an input funnel 19 is shown in Fig. 2, in which a magnetic module M3 is arranged in such a way that its activation causes an opening of the roller shutter bar 2 that passes , as will be described below in greater detail. A control unit 20 only indicated in this case deals with the corresponding implementation of the control orders in a control of the M3 magnets. Otherwise, Fig. 2b corresponds to Fig. 2a.

The function of the "opening" of individual bars or bar areas, can be represented in the best way by Fig. 4. Fig. 4a shows there! -for the embodiment with carriage - the final area of the screen 1 analogously to Fig. 3 in perspective view and in the figures Figs. 4b and 4c in two side views, representing for a better explanation of the interaction of the drive elements, all bars 2 closed, also although in this position the two upper bars 2 should be open.

Before deepening the interaction of all the constructive parts, the structure of the individual glutton element 4 is first presented by the perspective representation thereof in Fig. 5. The pivoting element 6 can be seen first, which is fixed at the end of the front side of the bar 2. The pivoting element 6 is in this case pivotally arranged through the pivot axis 3 in the stopping element 7, guiding a spring 8, of which only the free arm can be seen connected with the pivoting element 6, as a spiral spring around the pivot axis 3. The other free arm of the spring 8 is (not recognizable in Fig. 5) connected correspondingly with the stop element 7. This is achieved in this way that screen 1 does not pivot back in the open position either under the influence of wind.

In addition, it can be seen that the pivot shaft 3 glides through the stop element 7 and has at its end a lever 9 arranged in a rotation-resistant manner. Two magnets M1 and M2 are used for magnetic actuation, the first one being arranged at the upper free end of the pivoting element 6 and the second at the lower end of the lever 9. Two additional M3 and M4 magnets are fixed on a carriage 10 , as can be seen from figures 3 and 4a. The carriage 10 can be moved vertically in this case by means of a glutton 11 along a glutton rail 12 disposed inside the glutton profile 5. The magnets M1 and M3 in this case repel, so that during a movement of the carriage 10 downwards, there is an opening of the bars 2 connected with the pivoting elements 6. If the carriage 10 moves on the contrary upwards, the magnets M2 (on the lever 9) and M4 repel and a closure occurs of the corresponding bar 2. As already mentioned, the magnets M4 can be renounced in the version without carriage shown in Fig. 2b, since the closing of bars 2 already opened is produced by forced guidance when the screen 1 is raised.

The exact arrangement of magnets M1 to M4 follows in the best way of Figs. 4th to 4th. It can be clearly seen - as already explained with respect to Fig. 5, that the magnets M1 are incorporated in the upper area of the pivoting element 6 and that the magnets M2 are located in the lower area of the lever 9. While the Bottom representation is correctly represented in Figs. 4a to 4c, at least the second bar 2 should be open from above, since magnets M1 and M3 also repel. In the position shown, however, the spatial proximity of these two magnets M1 and M3 can be recognized very clearly, thus producing a reliable opening of the corresponding bars 2.

In Fig. 4a, as! as in Fig. 5, the articulated connection between the glut elements 4 in each adjacent case can also be clearly recognized. For this purpose, a connecting element 13 is used, which has a longitudinal hole 14 at its upper end, to enable a longitudinal displacement of two adjacent bars 2. In Fig. 5, the connection element 13 of the glutton element (not shown) disposed above is shown above the glutton element 4. The bars 2 of the screen 1 are therefore joined together in an articulated manner, with the exception of mutual engagement, as in the case of "normal" roller blinds. In this way, the screen 1 can be wound in a known manner on a winding tube 15 in a roller shutter box 16, as shown in Figs. 2a and 2b. In this case, a mechanical glide roller 17 takes care that the screen 1 can be wound even in the "open" state, since after leaving the vertical glutton profile 5 by actuation on the open lever 9, a closure occurs forced guidance of the bars 2, before they are rolled up, so that a

normal roller blind function.

To achieve the articulated connection, the connection element 13 is not only rotatably housed in the pivot axis area 3, the connection element 13 also has an axis 18 in its lower zone, which is engaged 5 in a corresponding recess of the stop element -not shown- arranged below, and is rotatably connected to it.
