Description

Roller shutters for a skylight

The invention relates to a roof window roller shutter for outdoor installation over a roof window according to the preamble of claim 1.

Such shutters are mounted from the outside via a roof window and are located after installation in a predetermined by the inclination of the roof, inclined to the horizontal position. If the roof window is to be opened, the roller shutter must be mounted so that a window wing of the roof window can be swung outward.

In the case of the known skylights, it is disadvantageous that they either completely shade the skylight, so that no sunlight penetrates into the interior of the building or has to be pulled up completely or partially, so that the bright sun falls on the exposed sections of the skylight and becomes one strong indoor heating may occur.

To solve these problems so far used on the roof windows mounted blinds. However, the incident sunlight strikes directly on the roof window, which is often designed today as a double or multi-walled insulating glass. It therefore comes to a strong local heating and thus also to a deterioration of the indoor environment.

Venetian blinds for installation on building facades or for vertical building openings, on the other hand, are widely used today. However, these are not suitable for shading a roof window and / or local assembly.

Thus, for example, EP 330 192 B1 or PCT / AT94 / 00 130 shows a roller shutter which can be opened and which works according to the following principle: A pull chain is connected in an articulated manner to the slats or armor bars of the roller shutter curtain, each slat being connected to one another a Verstellkette is connected, the members of which can be moved or swung against the Zugkettengliedern in the normal direction to the surface of the shutter curtain, for example, by the fact that the adjustment chain is stopped while the pull chain is still running in the feed or extension direction of the shutter hanging.

However, it is not apparent from the cited documents how the shutter mechanism is to be actuated or controlled.

The roller shutter shown in WO 99/41480 also works on the same principle, but it already has an actuating mechanism for the shutter mechanism. The slats of the roller shutter curtain are connected in an articulated manner to a pull chain at their two ends at the ends, the points of articulation of the two pull chains on the slat being offset from one another. As a result, the slats can be adjusted by pressing a pull chain relative to the other. For shuttering the blinds hanging a separate adjustment mechanism is provided there. For this purpose, with each lamella, on the one hand, pivot levers are non-rotatably connected, with which the lamella can be pivoted about the lamella pivot axis. The pull chain is articulated on the other side on the slats on the slat pivot axis. For this purpose, the pivot levers each have an outwardly projecting crank section, which is guided in a normal direction to the roller shutter surface movable guide rail. For the movement of the guide rail while a hand lever is provided, which is pivotally connected to the guide rail and thus allows an adjustment of the position of the guide rail in the normal direction to the roller shutter surface and thus the Jalousierstellung the slats. The movable guide rail and the hand lever mechanism are housed in a side frame of the shutter.

WO 99/41480 also proposes a further embodiment of the louverable roller shutter: A toothed rack is arranged to be displaceable up and down in the side frame. By hand lever, a gear is operated, which is in engagement with the rack. As a result, arranged on the side ends of the slats gears are actuated and thus rotated or louvered the slats. However, the same problems occur as in the embodiment with side-adjustable guide rail and pivot levers: The disadvantage of this is in particular that the hand lever is necessarily on the same side of the window as the shutter, you do not want to change the structure of the entire window. The roller shutter must therefore be either umständ- lent operated from the outside or attached to the window inside to provide the user the jalousie function comfortably. As a result, the beschattende building heats up unnecessarily, since the sunshine unabgeschattet on the (insulating) glass of the window meets, also the roller shutter can thus ensure no burglary. Furthermore, for the RoII- load corresponding installation space inside the building is needed. Furthermore, in addition to rattling when lowering the shutter to an abra- siven wear of the pivot lever and a cancel the same come, since the position of the guide rail can be made even with raised roller shutter on "blinds", whereby the slats or the thereto When the roller shutter curtain retracts, however, the slats are only swiveled back onto the winding shaft by the weight of the respective slat so that the roller shutter can only be tilted vertically or sufficiently inclined Surfaces can be used, that is unsuitable for skylights.

Another Venetian blind is shown in the European patent application EP 0 687 793 A1. In this case, the slats to be shuttered shutter blinds frontal approaches, which extend vertically in the closed position of the shutter curtain and are guided in a guide slot in the side frame of the shutter. The guide slot extends from top to bottom along the side frame by fixedly arranged blocks and rotatably arranged rotors therethrough. In this case, the rotors are arranged so that the lugs on the lamellae are at the level of the rotors when the shutter curtain reaches its lowest position. In this position, the lamellae can now be twisted over their lateral extensions and the rotors. For this purpose, the rotors are each connected via a rotary lever with a common actuating rod. Again, the operating rod must necessarily be arranged on the same side of the window as the roller shutter. In addition, a malfunction in not fully closed position of the shutter hanging can lead to serious damage.

In order to overcome these disadvantages in the case of blinds which can be activated by means of a separate louvre actuating mechanism, various approaches have been proposed for coupling the shuttering function to the advancement of the roller shutter curtain. But even these jalousable facade shutters with such couplings are not suitable for attachment to a skylight.

Thus, coupling is common, see e.g. PCT / AT93 / 00105, EP 1 130 212 A2, Fig. 5, EP 0 382 172 B1, actuation arrangements have been proposed in which a coupling of extension of the roller shutter curtain and pivoting of the louvres slats is carried out by fixedly mounted hooks, in which at the lamella fastened counter hook while passing forcibly intervene.

In the case of the sliding shutters according to PCT / AT93 / 00105, the respective slat, as well as the associated tension chain and adjusting chain link, each have the same cross section, wherein the pivot lever, by means of which the adjusting chain is pivotable relative to the tension chain, is formed by the slat itself. When the roller shutter moves down, the adjusting chain is simultaneously held in place to trigger the shutter function. This is done with a shown in Fig. 35 to 39 of PCT / AT93 / 00105, attached to the adjusting roller shutter hook or elbow, which folds when shutting down by a spring or by gravity and slides on a fixedly mounted hook along. When the roller shutter is raised again, the angle piece moves over the hook and is held by the hook when the roller shutter curtain is lowered again, so that, when the roller shutter curtain is lowered further, all slats connected to the adjusting chain are pivoted upwards.

By contrast, EP 1 130 212 A2 shows a plug-in part which can be inserted laterally into a slat profile and which can be connected on the outside to a pull chain via a bore and to an adjusting chain on the inside via a different bore. The roller shutter curtain is guided over the pull chain in vertical guide rails. One of the Verstellkettenglieder has in the normal direction to the roller shutter hanging surface an outwardly projecting hook which is gripped by a counter-hook when shutting down the shutter hanging, which are pivotally mounted on the side guide rail, whereby the shutter is effected.

EP 0 382 172 B1 also shows a roller blind which can be controlled, in which the sliding movement is coupled to the advancing movement of the roller shutter curtain. In this case, an attached to an adjusting chain link hooks on a deflectable over a pivot lever stationary, but pivotally arranged counter hook arrangement passes. When lowering the hook slides past an inclined surface of the pressed against the hook hook arrangement. A Venetian blind takes place only after the adjusting chain link hooks with the hook after a renewed startup and lowering of the shutter curtain in the Gegenhakenanordung.

The problem with these arrangements, however, is that the positive coupling device is located outside of the closed parts of the shutter and is therefore exposed to weathering. Furthermore, such a structure is not only unstable, maintenance-prone, visually ugly and requires much space due to the sweeping design, but also brings a difficult or inaccurate operation with it, since a multiple up and Abverfahren the shutter is necessary to trigger the shutter, to lock and unlock and / or a strong rattling when passing by the fixed hook is essential.

Other developments concerned in the side frames of blinds blinds built-in pivoting mechanisms for shuttering the slats of the shutter curtain, whereby these pivoting mechanisms are constructed so that the pivoting of the slats is positively coupled with the feed of the shutter curtain.

Thus, DE 198 42 502 A1 shows a roller shutter curtain with loose slats, which are connected via a laterally arranged by the slats pull chain. By means of the pull chain, pivoting levers are rotatably pushed through and at one end connected in a rotationally fixed manner to the lamellae and at the other end moved in a guide rail. lent, which is adjustable via an adjusting mechanism in the normal direction to the roller shutter curtain. The adjusting mechanism in this case comprises an actuating strip arranged in the guide rail, which is displaceable in the guide rail via corresponding cams in the normal direction to the roller shutter curtain. In this case, a hand lever is proposed for actuating the adjusting mechanism; On the other hand, however, a coupling of the adjusting mechanism with the unwinding of the winding shaft of the roller shutter is already shown: A lever arrangement is actuated via a switching mandrel arranged on the winding shaft when the winding shaft has made one revolution and the switching mandrel passes the lever arrangement. At the lever assembly, a Bowden cable is mounted, which is in communication with the adjustment mechanism for the guide rail. In this case, the adjusting mechanism is triggered during the first revolution of the winding shaft. This means that the actuating bar enters the jalousie position and newly developed lamellae must first be guided into the side guide rail with a funnel-like threading area, as a result of which, due to the striking of the pivot levers, there is constant rattling. Even when rewinding on the winding shaft problems occur because the actuator bar may still be in the operating position.

In order to prevent a constant opening and closing of the slats when lowering the shutter curtain on the one hand, a damper is proposed, which dampens after the slats of the slats against refolding of the slats. In this solution, it is difficult to adjust the winding shaft diameter on the building opening, that in a building opening completely covering the position of the shutter curtain also a louver is possible and not only in an arbitrary, determined by the winding shaft diameter position. On the other hand, a lock against refolding or a latch can be provided, which engages as soon as the guide rail or actuating bar is in the Jalousierstellung. Then, however, to release the latching connection, which is intended to prevent the continuous opening and closing, it is necessary to re-start the roller shutter curtain, ie, if it is not desired to raise the unit or the upholstery is to be canceled. Apart from that, the structure proposed here is relatively complex and even due to the taking place via a Bowden cable coupling the winding shaft movement with the louvers of the slats susceptible to maintenance, due to the adjustment of the actuating bar even during the first revolution of the winding shaft rattling when draining the shutter curtain can not be avoided.

Another Venetian blinds with integrated in the side frames of the blind shutter mechanism, which causes a forced coupling of the shutter movement with the advancing movement of the shutter curtain, can be found in the Austrian patent AT 403829 B. Also, the shutter shown there has mutually loose slats, which are fastened to a pull chain through which pivoting pivot lever are pushed through, on the one hand rotatably connected to the blades and the other end are guided in an adjustment chain, via the pivoting of the pivot lever and thus the Slats takes place. On one of the adjusting chain links, a jalousing hook guided in the side frame is provided for the jalousing mechanism. The shutter hook is guided when lowering the shutter on an inclined plane of a switch blade in a slotted guide with a catch channel. When the roller shutter is lifted again, the louver hooks with a catch hook above the catch channel, which deflects the pivoting levers connected to the louver hook via the adjustment chain and thus causes all louvres to be shuttered to be swung. If, on the other hand, the roller shutter curtain is pulled up again after the louver hook has left the catching channel, the switch tongue conceals the inlet to the catch channel of the ball guide. As a result, the shutter hook on the adjusting chain link when re-tightening runs into a located on the opposite side of the switch blade channel, whereby the switch blade is pushed back on further pulling the shutter back to the starting position. The Zugkettenglieder and Verstellkettenglieder consist of flexible spring steel, are placed on the only actuating pieces. As a result, the structure obviously gains the necessary flexibility to prevent the roller shutter curtain from being jarred by the jalousing hook passing through the venetian blind. In the case of the sliding blind according to EP 0 023 974, a control jaw, which is arranged in a stationary manner in both side frames of the roller shutter, is provided in order to effect the shuttering of the shutter. The slats of the roller shutter curtain are guided over a pull chain, through which a pivot lever is performed, the outer crank portion is rotatably guided in an adjustment chain. At the top, to louvered blade of the crank pin of the pivot lever protrudes through the adjustment chain further out into the side frame of the shutter inside, in which is located next to the adjustment chain of the control jaws. When you release the shutter that acts as a control pin, outer crank portion of the pivot lever hits an inclined plane of the control back and is thus deflected in the normal direction to Rollladenbehangoberfläche outwards, so that all aufjalousierenden slats are aufjalousiert existing on Verstellkette and the pivot levers pivoting compound. When the roller shutter curtain is retracted upwardly, the control pin enters an upwardly inclined return passage which opens into the vertical passageway in which the control pin is guided when the shutter loader is in the unfolded position. From there, the roller shutter can either be further lowered or pulled up. When it is pulled up, the control pin presses against the oblique plane of the control jaw formed as a leaf spring, pushes this leaf spring aside and then continues its upward movement. This results in a strong noise, as well as the discharge of the shutter when the control pin jumps from the inclined plane on the return passage away on a substantially horizontally extending portion of the control box. Furthermore, this arrangement is susceptible to wear due to the continuous change loading of the leaf spring of the inclined plane, since a large load acts on this inclined plane of the control bag, which consists only of spring steel.

In order to avoid these disadvantages, EP 0 023 974 has already proposed an additional rather pivoting cam which can push aside the inclined plane of the control bag when a positioning cam mounted on the front side of the roller shutter hanging below each control pin passes by the pivoting cam. This will cause the vertical channel in which the control pin is in a non-deployed condition. When the roller shutter curtain is running, it is initially opened when the roller shutter curtain is lowered. To close it again, an additional control cam is mounted above the control pin on the front side of the shutter hanging. In a further draining the roller shutter hanging the vertical passageway is thus initially closed. Thereafter, the roller shutter must be raised again so far that the control pin comes to rest above the inclined plane of the control bag. Upon a renewed lowering of the shutter, the control pin is then deflected in the normal direction to the roller shutter hanging surface, as in the first embodiment. However, even in this embodiment, the above-mentioned disadvantages are not completely overcome.

This also applies to the further embodiment proposed in EP 0 023 974, in which the vertical passage channel is separated by a further spring in a downward and an upward track, so that the roller shutter curtain must first be lowered so far that the control pin, the separating spring move aside and then the shutter curtain must be raised again so far that the control pin runs in the up-lane until reaching the oblique plane forming spring and pushes aside, whereupon the shutter is re-louvered at a renewed reductions, as the control pin on the crooked Level of the control bag is deflected.

EP 0 189 091 B1 also shows a shutter which can be shuttered for façade windows, which is pivoted during the rolling of the roller shutter curtain, wherein the roller shutter completely covers the opening to be shaded at the beginning of the roller shutter and is substantially fully extended at the end of the tilting. The louvering works by deflecting the gravity generated by the weight of the vertically arranged roller blind hanging. In addition to the pull chain on which the slats of the curtain are lowered, the roller shutter on a Ausstellkette, which is connected to a base support, which in turn in a base profile (bottom roller shutter slat) is pivotally mounted around a pin, wherein the pin in a Slot can slide back and forth. Further, a third chain is provided with slit chain links, wherein on the slit chain links slide curves are provided and on the slats the sliding curves facing sliding surfaces. When attaching the sisprofils on the window sill swings up the base support and transmits this movement to the deployment chain. In support of the respective lamella is deflected over the abutment order sliding curve / sliding surface.

On this basis, it is therefore an object of the present invention to provide a shading device for a roof window, with the degree of shading of the window opening is adjustable and an internal heating can be avoided anyway.

This object is achieved with the features of claim 1.

According to the invention, a roof window roller shutter is proposed for outdoor installation over a roof window, which is louvers. With the roller shutter according to the invention thus succeeds for the first time to shadow a roof window opening from the outside.

Advantageously, the skylight roller shutter a roller shutter hanging from at least part of a pivot axis extending in the longitudinal direction pivot axis having slats, a Schwenkausführanordnung for transmitting a pivoting power on the pivotable slats, and a pivoting effecting arrangement for generating the pivoting power for a to the situation the roller shutter hanging coupled, automatic ur \ d simultaneous louvering all pivotable slats on the Schwenkausführanordnung during the Unwinding of the shutter hanging and Zujalousieren during the winding.

By providing such a swinging action arrangement for generating the swinging power, manual operation and the hand levers or the like necessary therefor, which make either an inside mounting or an outside operation required, can be avoided. It is advantageous if the roller shutter is formed so that the shutter curtain completely covers the opening to be shaded at the beginning of the louvering and is fully extended at the end of the louvering substantially.

In this way it is ensured that the louvered roller shutter is protected against over-discharge. The Aufschwenkendposition is reached only when fully extended roller shutter curtain, whereby a given backup against misuse is given. In addition, the control of the roller shutter according to the invention is very simple, since the roller shutter curtain already fully covers the opening to be shaded at the beginning of the louvering and the Aufjalousierbewegung is executed only at a further draining. Intermediate, about hooking in certain Gegenhakenanordnungen are not necessary to trigger the Aufjalousierbewegung. Even when rewinding the roller blinds, it is sufficient to move the roller shutter counter to the direction of extension without the need for certain intermediate cables for unhooking from a counter hook arrangement.

The roof window roller shutter thus only requires an easy-to-implement control, so that it is well suited for a motor drive of up and Abwickeins the shutter hanging. In this case, the control of the engine can be very simple: It is sufficient to allow the operator to turn on the engine and turning off the engine in any desired position of the shutter curtain and provide an automatic shutdown of the engine upon reaching the position of the shutter curtain. Intermediate trains need not be stored in the engine control.

The pivoting effecting arrangement can be realized, for example, via electromagnets or electromagnetically actuated piston valves which pivot the pivotable lamellae in the normal direction to the roller shutter surface, when a predetermined point of the roller shutter curtain with a corresponding signal generator exceeds a predetermined position during the movement of the roller shutter curtain or retraction reached the shutter hanging. As a signal generator can be provided, for example, a sliding contact. Advantageous in the sense of a cost-effective and simple construction, however, is a pivoting effecting arrangement that decomposes the winding and unwinding of the roller shutter hanging effecting power in a feed power component and a pivot power component, so that the pivoting action arrangement does not require its own power supply or own motor, in particular a mechanical positive coupling of predetermined positions of the shutter blind with associated blind positions of the shutter hanging. The roller shutter can thus be operated with only a motor drive or completely by hand by merely lowering or raising. In this case, different gearboxes are conceivable as a pivoting action arrangement, which disassemble the winding and unwinding of the roller shutter hanging effecting power into a corresponding feed and pivoting performance upon reaching the respective position of the roller shutter curtain.

Preferably, the Schwenkausführanordnung has a pivotable with all pivotable lamellae related pivoting portion and operable by the pivoting action, with the pivoting section associated attack section and the pivoting effect arrangement at least one extending in the extension of the Rollladenbehangs, stationary Steuerkanalnut in which the attacking section is guided , In this way, a one-to-one translation of a curvature of the control channel groove into a louver position of all louvers, i. that in the normal direction to the roller shutter hanging surface extending direction components of the control channel groove are converted into a pivoting of the pivotable blades.

With this construction, it is thus possible to implement objectively the feature functionally defined in the characterizing part of claim 1 with structurally simple means. Further features mentioned in the dependent claims relate to the smoothest possible outward movement of the roller shutter curtain as well as the implementation of tolerances in order to lower the requirements for the accuracy of the motor control or the manual operation of the shutter. So it is advantageous if the pivoting action arrangement is arranged so that when unwinding the blinds hanging a pivoting power for the louvering and winding a pivoting power for the louvers is generated and transmitted, which increases with extending in the extension direction roller shutter curtain. Because due to mechanical or structural conditions, such as rubbing aufzuschwenkenden slats or the like. There is an initial resistance against the louvered, which is easier overcome if the pivoting power begins only gently and only increases with time, especially if it rises steadily. As a result of the increase, an exponential course of the increase in the pivoting power has proven to be favorable. In this case, the pivoting power is generated and transmitted as long as a predetermined point of the roller shutter curtain is located in a predetermined shutter section extending in the extension direction of the roller shutter curtain.

A representational implementation of this desired pivoting power generation and transmission in the predetermined, extending in the extension direction Jalousierabschnitt can be achieved in that the Steuerkanalnut a the jalousier section corresponding section with a normal direction to the roller shutter hanging surface extending, corresponding to the Aufjalousierbewegung directional component, in particular with a in the extension direction rising direction component preferably steadily and particularly preferably exponentially increasing direction component.

In contrast, the fact that the pivoting action arrangement is arranged so that the Jalousierabschnitt a down to the fully extended position of the shutter curtain hanging outlet tolerance section is followed, in which the transmitted pivoting power is constant, the installation of an exactly working expensive, expensive servomotor as a drive for the up - And unwinding of the roller shutter curtain or similar measures are avoided because it is ensured even with simpler and cheaper drives that despite engine tolerance, the substantially fully extended shutter position is reliably achieved, ie that the shutter is completely aufjalousiert in each case. This also applies to a manual and thus limited in their accuracy operation of the shutter. Also, this measure can be implemented in a simple manner representatively, in which a purely extending in the extension direction section of the control channel is provided, which corresponds to the outlet tolerance and the subordinate portion of the Jalousierabschnitt the Steuerkanalnut is arranged downstream.

Advantageously, the pivoting action arrangement is also set up such that a blocking section is connected upstream of the shutter section, in which a pivoting power for a blocking pivoting into a mutually braced position of the slats and during winding of the roller shutter curtain a pivoting power for unlocking pivoting in a starting position with mutually loose slats generated and transmitted. In this case, the locking portion is preceded by a forward section, in which the roller shutter curtain occupies the starting position with mutually loose slats in which no pivoting position is generated and transmitted.

As a result, the roller shutter curtain can first be drained off with mutually loose slats, so that the slats are movable against each other during winding and unwinding of the winding shaft and no unnecessary mutually directed strains are built up during the run of the roller shutter curtain, which prematurely due to the constant load Wear of the roller shutter curtain would lead. Upon reaching the barrier section, the slats are then swung successively to the end of the barrier section and thus braced against each other. In a situation in which the shutter curtain completely covers the opening to be shaded, thus a mutually strained and thus burglar-proof position of the slats is achieved. For this purpose, in the embodiment of the louverable roller shutter with the control channel groove, a section corresponding to the blocking section may be provided in the control channel groove, which has a directional component in the normal direction corresponding to the blocking pivoting movement in the normal direction to the roller shutter hanging surface and is arranged upstream of the section corresponding to the louver section, the control channel groove seen on the side of the winding shaft of the shutter at a height in the normal direction to the roller shutter hanging surface begins, which corresponds to the above-mentioned starting position.

Advantageous in terms of a simpler drive design and control and the associated greater positional tolerances of the desired Roha loading hangers may be located between the locking portion and the Jalousierabschnitt arranged intermediate tolerance section in which the transmitted pivoting power is constant, as already above with respect to the outlet - carried out leranzabschnitt. In this case, the intermediate tolerance section may be assigned a section of the control channel groove which is located between the section of the control channel groove assigned to the blocking section and the section of the control channel groove corresponding to the louver section.

The roller shutter curtain can be driven via an example attached to the front side of the slats pull chain or attached with two on both end faces on the slats pull chains. Advantageously, it is guided in the extension direction, in particular via the pull chain (s). The control channel groove of the pivoting suspension arrangement can then be arranged laterally of the pull chain, or a control channel groove can be arranged on both sides of the roller shutter curtain, each having a mutually synchronous course. Advantageously, each of the control channel grooves is formed in a fixedly arranged gate piece, which can be received in a side frame of the shutter, so that an over the Steuerkanalnut the Schwenkbewirkungsanan- order taking place the Schwenkausführanordnung protected within the side frame and thus in a sealed against the environment housing can take place.

In this case, the side frame advantageously has two stop surfaces running parallel to the roller shutter curtain surface, which are located in the normal direction to the roller shutter curtain surface above and below the pull chain and thus narrow a guide gap in which the pull chain is guided, in particular with play , while the abutment surfaces may be coated with a material of low sliding friction, for example made of plastic, to those for extension the roller shutter necessary power to keep low. However, it would also be a roller bearing, conceivable with flat cage rails.

Thus, the tension chain and thus the entire roller shutter curtain during the winding and unwinding at a fixed height in the normal direction to the roller shutter curtain surface is fixed over the guide gap formed by the two stop surfaces. The entry of the pull chain of the roller shutter curtain, or the lowest chain link in the guide gap when unwinding the fully wound shutter can thus be accurately and without rattling, since the two Anschlagungsflächen provided on the stationary side frame and thus fixed in height.

The Schwenkausführanordnung may have a designed as an adjustment chain pivoting, wherein the Verstellkettenglieder each having an associated blade pivoting portion. The engagement portion may be formed in this case by an engaging at least one member of the adjusting chain, guided in the Steuerkanalnut engagement bolt, for example by a fixedly connected to the member of the adjustment chain engagement bolt. With this arrangement, it is possible to transfer the sequence of the jalousing and blocking movement 1: n predetermined by the sections of the control channel groove described above to all the lamellas to be pivoted. In this case, the adjusting chain can also be arranged on the front side of the lamellae and arranged together with the control channel groove in the side arms of the roller shutter, so that a completely closed pivoting mechanism of the roller shutter results.

In a further improved embodiment of the invention, however, the Schwenkausführanordnung for each pivotable lamella on a pivot lever which has a rotatably connected to the lamella and aligned with its pivot axis hinge pin, which in turn through a likewise aligned with the pivot axis through hole of the pull chain in lamella longitudinal direction to the outside is performed. At the hinge pin eccentrically connects via a crank or a crank section to an attack bolt, which in an in driving direction extending side guide rail is guided, the pivot lever is thus integrally formed from the hinge pin, the crank and the attack bolt. The side guide rail in turn has at least one, preferably two guide pins which are each movably received in a control channel groove. The hinge pins form the pivoting portion of the Schwenkausführanordnung and the side guide rail with the attack bolts and the at least one guide pin the attack section. In the embodiment with two guide pins on the side guide rail, which are each movably received in a separate Steuerkanalnut, it is understood that guide rails are then arranged so that the two guide pins can run synchronously to each other, so for example translationally offset from each other, ie that the two Control channel grooves have the same course and all guide pins must be at the same position in the respective Steuerkanalnut at any time in order to effect a uniform movement of the guide rail and thus guided over the guided in the guide rail pivoting a uniform movement of all slats to be pivoted.

With this advantageous development of the invention, it is possible to use the course of the control channel grooves 1: n defined by the above-described sections without the need for an additional adjustment chain, and thus to transfer them to all lamellae to be pivoted, with a construction which is less error-prone and requires less maintenance. ^v

It is advantageous to actuate the slats on both sides of the shutter blind provided guide rails / control channel grooves.

In this case, the guide rail in the two in each case in a separate, within the side frame fixedly arranged gate link formed Steuerkanalnuten run over the guide pin run in roller shutter curtain extension direction and perform the predetermined by the above-described sections of Steuerkanalnuten height adjustments. For displacing the guide rail or the two guide rails arranged on the side of the roller shutter curtain, in each case a side guide feed device is provided as part of the pivoting effecting arrangement. The side guide rail feed device is constructed in such a way that the guide rail is advanced along the course of the control channel groove as soon as a defined starting point has been reached during the extension of the roller shutter curtain. In addition, to retract back to the starting position of the side guide rail, a side guide rail return device may be provided as part of the pivoting action arrangement. The side guide rail return device is constructed so that the side guide rail is pushed back during the winding of the shutter curtain until reaching the starting point along the course of Steuerkanalnut.

The lateral guide rail feed device can be provided, for example, as a stop provided in the guide rail for the lowermost of the engagement bolt, so that the lowermost attack bolt inevitably entrains the guide rail when it abuts against the stop during the extension of the roller shutter curtain. Alternatively, a laterally arranged on the roller blind curtain side guide rail driver for the side guide rail may be provided, the side guide rail must also have a counter to the extension direction stop, but must be adapted for the side guide rail driver on roller shutter curtain, so that the side guide rail the desired Path along the course of Steuerkanalnut performs. The side guide rail driver can be embodied, for example, as a slip-on piece which is attached to the roller shutter curtain in a section above the pivotable slats, in particular to a draw chain link of the pull chain, which is not pivotable with one of the first, following the pivotable slats Slats is connected. The stop on the side guide rail can be easily formed by the winding shaft directed towards the front side of the guide rail. When extending the shutter, the guide rail is thus taken away when the pivot lever of all pivotable slats are in the guide rail in the retracted state and can be swung on. As a side guide rail retracting device may be formed against the side guide rail from below ago biasing spring which biases the guide rail upwards against the force applied by the driver, so that the guide rail upon retraction of the shutter along the course of Steuerkanalnut upward, ie pushed back to the winding shaft. Theoretically, it would also be conceivable to adjust the guide rail via solenoid valve piston slide or the like synchronized with the roller shutter hanging movement.

However, in order to make the construction of the return device easy and low maintenance, it is advantageous if the side guide rail return device comprises a provided on the side guide rail return latch, which engages a laterally arranged on the roller shutter curtain Rückholriegel-driver during extension of the shutter curtain and release only when rewinding the Rollladenbehangs , when the desired point on the line in the extension direction of the roller shutter curtain is reached. Advantageously, while the Rückholriegel-driver at the same time be the side guide rail driver, while the stop for the side guide rail driver is provided on the return latch, i. if the return bar is provided, for example, on the side facing the winding shaft of the shutter towards the side guide rail.

In order to grasp the driver, the return bar is pivotally hinged to the side guide rail, so that the driver on impact on the eccentric stop a pivoting moment on the Rückholriegel affects and the Rückholriegel is so pivoted that he with a corre sponding section the Carrier engages behind. For this purpose, the return latch is advantageously designed as a return fork whose fork opening initially faces the return bolt driver at an angle, the stop being formed on one of the fork legs above the fork opening. Upon impact of the Rückholriegel-driver, the return fork is thus pivoted so far that one of the fork legs engages behind the driver, whereas the other fork leg, the transmitted via the Rückholriegel-driver force in the white direct extension of the shutter transfers to the side guide rail so that it is moved when extending the shutter downwards, ie away from the winding shaft. In this position, the return latch could be held, for example via a spring, until the guide rail strikes the guide channel groove on the return of RoII- loading hanging over her (n) guide pin and the driver transmits the force required to pivot back of the return bar.

Preferably, however, in a respect to the roller shutter curtain also fixedly arranged link piece, preferably in the side frame fixedly arranged link piece a Rückholriegel cam provided along which a return bolt provided Rückholriegel guide pin when extending and rewinding the Rollladenbehangs is performed.

The Rückholriegel control cam may have a sliding edge portion and a groove portion and be set so that the Rückholriegel guide pin is pressed during the extension of the roller shutter hanging against the sliding edge portion. The sliding edge section in this case has a component in the normal direction to the roller shutter curtain surface, so that a pivoting movement of the return bar is allowed or released when the return bar guide pin is arranged outside the lever line from the stop to the pivot point of the return bar on the return bar and on the Gleitkanten- Section along slides. At the same time, movement of the lateral guide rail in the extension direction of the roller shutter curtain is also permitted by the component of the sliding edge section pointing in the extension direction of the roller shutter curtain, so that no blocking of the extension movement of the roller shutter curtain is to be feared during the pivoting of the return latch about the return latch driver. The return bar control cam further has a groove portion following the sliding edge portion in the roller shutter hanging extension direction, which has the same course as the guide channel groove (s), the return bar guide pin in the groove portion being synchronized with the guide pin Guide pin in the guide channel (s) runs. A further advantageous embodiment of the roller shutter according to the invention relates to a motor drive of the shutter, which is advantageously housed in a separate from the winding shaft drive shaft which is circumferentially equipped with toothed cams over which the drive shaft can engage the shutter to be moved curtain. If the pull chain in this case consists of individual, at least in the region of the pivotable slats articulated interconnected Zugkettengliedern, which are each connected to the slats of the shutter blind, one or more recesses may be provided in the Zugkettengliedern, which are associated with the toothed cam of the drive shaft, so that the drive can take place via the pull chain. For common drive motors, it has been found to be suitable if the length of the outlet tolerance section or the outlet tolerance associated portion in the control channel and the intermediate tolerance section or the Zwischenstoleranz-section associated portion in the Steuerkanalnut a Motor accuracy of +/- 3 ° drive shaft angle corresponds.

The Zugkettenglieder can, if they are associated with a pivotable blade, be connected via the associated hinge pin of the pivot lever with the blade, wherein the hinge pin is guided through a hinge eye, which connects two Zugkettenglieder articulated together. The pivot lever can then be connected via an adjoining at its hinge pin Einsteckstück with the associated pivotable lamella, when this lamella consists of a frontally open profile, in which the male is inserted.

If, however, the tension chain link is assigned to a non-pivotable lamella, a structure of the tension chain link can be provided which has an insertion piece adjoining the tension chain link on the side of the lamella, with which the tension chain link is inserted directly into the respective lamella. It is advantageous in terms of mass production of the slats, if all slats, whether pivoting or not, consist of the same frontally open profile, such as a plastic or aluminum profile. The lamellar profile can In this case, advantageously, have an upper and a lower, in each case towards the front side open Keder groove in the extension direction of the roller shutter, can be inserted into the rubber profiles that seal the gap between the slats in the non-louvered state. In this case, the non-pivotable lamellae can be connected via inserted into their Kedernuten connection rubber profiles with each of the above and / or below subsequent lamellae, wherein the connection rubber profile in cross section has approximately the shape of a stylized bone or an aft. On the other hand, the louverable lamellae can each have, in their lower core grooves, a sealing rubber profile which, in cross-section, has approximately the shape of a tadpole and is merely connected to a lamella. The sealing rubber profile thus seals the gap between two successive lamellae in the non-floated state, whereas the successive lamellae can be lifted off each other when they are being louvered.

For a burglar-proof design of the roller shutter, it is also advantageous if at the lower end of the track of the roller shutter curtain a closure panel is provided which at least partially covers in the fully extended position of the shutter curtain at least the bottom slat and the bottom slat is not pivotable. In the shadowed opening completely covering the roller shutter curtain position (in the blocking position), a re-lifting of the roller shutter from below is therefore additionally thwarted.

Further advantageous developments are the subject matter of the further subclaims.

The individual features of the embodiments according to the claims can be combined arbitrarily, as far as appropriate.

First, reference is made to Figure 1, in which a mounted on a roof window 2 roller shutter 1 is shown.

The roof window 2 in this case has a glazing, which is taken from a window sash 10 a ¹ , which is arranged in a window frame, via which the roof window 2 is fixed to the roof of a building whose building opening covers it.

In this case, the roller shutter 1 has a roller shutter curtain 3 which can be sunned, as well as a surround of the roller shutter curtain 3, which is formed by a roller shutter box 4, side frame profiles 9 and an end panel 13, the lateral frame profiles 9 are connected at the ends provided by plug connectors 11 with the cover plate 13 (see Figures 1b and 1c) and are inserted at their other ends in corresponding receptacles on the shutter box 4.

The roller shutter 1 is shown with vollausgefahrenem and aufjalousiertem blind shutter 3. The roller shutter curtain 3 has a section with louvered or swiveling lamellae 5, which shadows most of the roof window 2, and a winding shaft side section with non-pivotable lamellae 6. In addition, the roller shutter curtain 3 has a non-pivotable, lowermost lamella 66, which extends to is drained under the end panel 13.

The roller shutter 1 is mounted from the outside on the roof window 2, in such a way that the roof window 2 can still be opened. That in such a way that the window sash 100 can be swung outwards in the roof room in the pivoting direction A by the operator.

FIG. 1b shows shutters 1 and roof windows 2 when the window position is completely open. It can be seen that the window sash 100 is received at about halfway height in the window frame 7, so that its lower half is pivoted outwards, while its upper half pivots inwards when the window 2 is opened. The roller shutter 1 is bolted on the side of the roller shutter box 4 in each case via a frontally hinged to the box 4 holding plate 112 with the two side slats of the window frame 7. Furthermore, the two side frame profiles 9 of the roller shutter 1 are slidably and pivotally connected to the outwardly swung portion of the window 2, in the region of the two lower corners of the sash 100, as will be explained in more detail below with reference to Figure 1d.

FIG. 1 d shows a cutout in the area of one of the two lower corners of the window sash 100. An angle piece 131 is attached to the window sash 100, which is guided via a window guide roller 135 in a window guide rail section 133 of the side frame profile 9 of the roller shutter 1. The side frame profile 9 also serves as a guide for the roller shutter curtain 3, whereby the shutter mechanism for the shutter function of the roller shutter curtain 3 is accommodated at least for the most part in the side frame profile 9, as will be explained below with reference to FIGS. 16 and 17 ,

FIG. 1c shows the roller shutter 4 mounted on the roof window 2 in a ventilation position in which it is held automatically supported by a spring by compensating the weight force of the roller load acting against the swiveling direction A by a spring force acting in the swiveling direction A. It can be seen from FIGS. 1 b and 1 c that the window sash 100 performs a substantially greater pivoting movement than the roller shutter 3. Because the lever arm from the pivot point of the sash 100 in the window frame 7 to the guide roller 135 in the side frame profile 9 of the shutter 1 is substantially shorter than the lever arm from the suspension of the shutter box 4 to the guide roller 135. Therefore, the window sash 10 via the guide roller 35 and slidably guided in the roller shutter profile 9.

The roller shutter box 4 consists of several items, namely a lower part, an upper cover panel 115, as well as the front side mounted thereon side parts 116, which in turn are covered with Seitenabdeckblenden 117. The shutter box 4 is connected via the hinged to its end faces holding plates 112 with the window frame 7, wherein the beidόn joints are housed in the side panels' 116 of the shutter box 4 disguised.

In the position shown in Figure 1a, the pivotable fins 5 are so far as aufjalousiert that while direct sunlight through the roof window 2 in the roof space and thus an extreme heating is avoided, however, remains released for the stylized person the view to the outside. Corresponding to the roof pitch, the angle corresponds to that of the swiveling ones

Slats 5 are jalousiert, in about 30 °. The maximum Aufjalou- sierwinkel example, be determined by a corresponding course of a Steuerkanalnut, the below still standing in detail will be explained. In this way shutters can be offered for different angles of inclination of the shade to be shaded. However, it is also possible to install a roller shutter with a larger maximum blind angle than the illustrated 30 ° to the roof window 2 and leave it to the user, the drawer hanging 3 only to the desired Aufjalousierstel- ment of the pivoting slats 5, or the engine control for the roller shutter drive, which will also be explained in more detail below standing on the inclination of shaded opening, here the sloping roof to adapt.

FIG. 2 shows the detail denoted by II in FIG. 1 in an enlarged view, namely a section of the roller shutter curtain 3 with louvers 5 and non-louvres 6. It can be seen that both the louvres 5 and the non-louvres 6 are of the same type wing-like curved hollow profile, in the present case of a plastic hollow profile, which is open at the front and in the extension direction R of the roller shutter hanging upper and lower side also have a frontally open Kedernut 53. On the one hand, this design has the advantage of a weight-saving construction of the moving parts of the roller shutter curtain. On the other hand, 5.6 components can be inserted with appropriately trained Einsteckstücken in the frontal openings 52 of the plastic profile of the slats. v

In the case of the non-pivotable slats 6, this could either be a plastic insert for covering the slat profile opening 52 or a chain link provided with a corresponding plug-in piece of a pull chain, as will be explained below. In the case of the pivotable lamellae 5, this could for example be an integrally formed on a corresponding insertion lever pivot lever of a swivel assembly for the lamella, with the pivoting blade 5 can be imparted a pivoting power with a directional component in the normal direction N to Rollladenbehang surface. In the case of the non-pivotable lamellae 6, in each case a piping section of an approximately bone-shaped connection profile 8, preferential Wise connecting rubber profiles be added, with which the lamellae 6 are connected to each other, so that there is not necessarily the need to connect them with an additional, either only on one or both ends of the lamellae arranged pull chain together. On the other hand, the pivotable lamellae 5 have sealing profiles 7, preferably sealing rubber profiles, inserted in their lower core grooves 53, so that they rest only on the lamella of the roller shutter curtain 3 following at the bottom and by a pivoting power with a normal direction N to the roller shutter support surface acting component can be louvered. The embodiment of the roller shutter curtain described above and shown in detail in FIG. 2 can be made the object of an independently patentable application per se, and in combination with other features described, described or claimed.

As is apparent from the figure 2, the pivotable slats 5 of the shutter blind 3 must be fastened to each other via end-side connecting parts, for example via subsequent to the openings 52 Einsteckstücke subsequent pivoting lever, which are guided in a suitable pull chain.

A corresponding roller shutter curtain section with inserted pivot levers and pull chain is shown in FIG.

The pivoting levers are designated overall by 59 and have a dashed line indicated insertion piece 64, with which they are inserted into the frontal opening 52 (see Fig. 2) of the slats 5 and the hollow profile of the lamellae 5 close the front side. The plug-in piece 64 is adjoined by a hinge pin section or hinge pin 54 projecting in the lamella longitudinal direction L, which is guided through a hinge eye between two links 19 of a pull chain 16. On the hinge pin 54 in turn connects a crank portion 53 of the pivot lever 59, via which an engaging portion 55 is eccentrically connected to the hinge pin, so that by applying a force or power on the attack bolt or attack section 55, the associated blade 5 to their in lamella longitudinal L extending pivot axis can be pivoted when the pull chain 16 is simultaneously supported in the normal direction N to the roller shutter hanging surface against the applied force.

The tension chain links of the pull chain 16 assigned to the pivotable lamellae 5 are designated overall by 19 and each consist of a support part 20 and a discharge part 10, one of which is shown in an exploded view in FIG. In this case, the tension chain links in the normal direction to the roller shutter hanging surface extending through openings 18, which will be explained as below, can be penetrated by drive cams of a drive shaft, so as to roll up and unwind the shutter curtain. The pull chain is thereby, as also explained below, guided in a guide gap between an upper and a lower guide surface, which - due to the inclination of the roof window 2 mainly on the side of the lower guide surface - when extending and winding the RoII- loading curtain to friction comes.

Such a, a pivotable blade 5 associated Zugkettenglied 19 and the support member 20 and the drain part 10 of the draw chain link 19 are shown in Figures 7 to 11 in detail, to which reference is made in the following.

The figures 7, 8 and 10 show the sequence of assembly of the support member 20 and the expiry part 10 to a finished chain link 19. The support member 20 is a one-piece metal part, in particular cast iron and essentially takes over the power transmission in the pull chain 16. Das Drain part 10, however, is a plastic-formed article on the support member 20 and serves to reduce the friction of running on the expiry part of the drawstring 16. Aη the support member includes in the longitudinal direction of the chain at one end a first connection lug 30 and the other end a second connection lug 40 in one piece, with the other connection lug 40,30 of the next chain link a hinge eye 31,41 for the hinge pin 54 (see Figure 3) form associated pivot lever 59, wherein the one connecting lug 40 is fork-shaped with a slot-shaped recess for the other connection lug 30 of the next chain link 19 is formed. The basic framework of the support member 20 is thereby formed by extending in the drive direction, arranged on both sides of the support member side webs, which are interconnected via cross-connecting ribs and thus the recesses 18 define. Projections 21 extending along the side webs protrude from the running surface FL of the carrying part 20 directed toward the discharge part 10, as well as projections 22 running along the front and rear cross-linking ribs, which form a socket for attaching the discharge part 10 which is shaped complementarily to the carrying part. In this case, the support member 20 is concavely curved toward the tread FL in accordance with the lamellar profile, wherein the drain member 10 has a complementary, concave curvature.

The support member 20 thus has a seen in the drive direction of the chain central tip on the side facing away from the drainage surface on which a central cross-connecting rib is provided with a central receptacle 60. Also, the drainage part has a structure of lateral lateral webs in the drive direction of the chain, which are connected by transverse ribs, protruding projections projecting along the side webs and front and rear cross-linking ribs in the direction of the supporting part, which are formed such that the drainage part can be attached to the support member.

In this plugged-on, preassembled state, the chain link 19 is shown in FIG. It can be seen that at the front and * of the rear cross-linking rib of the expiration portion 10 and at the protruding projections hinge eye sections 32,42 join that complement the hook-shaped hinge eye portions 31, 41 on the support member 20 complementary. Furthermore, it can be seen that an expansion dowel or press-in dowel designated 50 in the preassembled state of the chain link 19 comes into abutment in front of the opening 60, which is shown in detail in FIG. 9 from the direction of the surface opposite the drain surface.

In this case, a latching pin which is latched into the passage recess or catch opening 60 and which consists of concentrically arranged, cylindrical-segment-shaped handling posts 70 can be seen. The locking pin stands in not shown From the discharge part 10 to the support member 20 toward the passage opening 60 in alignment, wherein the zylingersegmentförmigen handling posts 70 are each provided with a detent with which they engage behind the enclosure of Rastaufneh- tion, so that the drain part in the shown in Figure 8 , premounted state is already latched onto the support member 20. In this case, the locking pins made of the material of the expiration part 10, namely plastic, and therefore elastic, so that they can be easily snapped or unlocked.

In order to reliably prevent unlatching of the cylindrical circumferential posts 70, the expansion dowel 50 is provided on the discharge part, which, as can be seen from the not yet installed state shown in Figure 7, connects via a predetermined breaking point aligned with the insertion opening on the drain part. The predetermined breaking point can be produced, for example, by a thin film connection formed between the expansion dowel 50 and the drain part during injection molding of the drain part. When the expansion dowel 50 is then pressed, as shown in FIG. 10, into an insertion opening formed within the detent pin by the cylinder segment-shaped peripheral posts 70, re-engagement of the cylinder segment-shaped peripheral posts 70 is effectively prevented, as is also apparent from FIG Top view of the support surface FL opposite surface of the support member in the region of the passage opening 60 is shown with pressed expansion dowel 50.

In contrast, FIG. 4 shows a section of the roller shutter curtain 3 with non-pivotable lamellae 6. One recognizes one of the dog-bone-shaped rubber profiles 8 with which the lamellae 6 are each connected to one another. In this case, the slats 6 are formed by the same, open-sided profile as shown in Figure 3, pivotable slats 5. In the frontal profile opening 52 is inserted in each case a chain link with its Einsteckstück 65, wherein the non-pivotable slats 6 existing roller shutter section Payload when discharging, rewinding and when the tambourine is deflated via the sealing rubber profile 8 and not via the individual tension chain links 17 provided in this area, which already differ from the tension chain links 19 in the roller shutter hanging section with pivotable lamellae in that they are not directly connected to one another.

The Zugkettenglieder 17 are formed from plastic and inserted into the lamellar profiles 6, wherein they follow the predetermined by the wing-like shape of the lamella curvature and just like the Zugkettenglieder 19 in the region of the pivotable lamellae 5 engagement openings 18 for drive cams of a drive shaft. Although the tension chain links 17 at their front and rear end in the extension direction R also have projections 71, 72 which look like hinge eye sections. On the one hand, however, the lugs serve to connect the first chain link 19 associated with the last pivotable lamella 5 to the following chain link 17 assigned to a non-pivoting lamella 6 and, on the other hand, to attach a further downwardly described lug piece of a side guide rail and return lug carrier Although the Aufsteckstück is only aufzustecken on one of the Zugkettenglieder 17, but for the sake of a higher number of pieces and part equality all Zugkettenglieder 17 are identical. Alternatively, however, the tension chain links 17 can also be connected to each other at their articulation-like extensions 71, 72.

As an alternative to the embodiment of the tension chain links 17 on the non-pivotable disks shown in FIG. 4, two-part chain links with a carrying part and a discharge part can also be used here.

Figures 5 and 6 show a further development of each of the pivot lever 59 and the one-piece piece 64 formed, connected to the pivotable blades 5 components. FIG. 6 shows detail VI in FIG.

Here, a schematized end view of the insertion pieces 64 of successive lamellae 5 is shown in FIG. The slats have seen in the extension direction at their lower ends a lug 80 and at its upper ends a lug 90,. From the mutually facing lugs 90, 80 aufein- on the following louvers 5, the lug 80 acts as a locking portion 80 and the lug 90 acts as a stop portion for the locking portion 80.

It can be seen that the locking portion 80 is formed as a locking mandrel projecting towards the opposite chain link, and the abutment portion 90 is formed as a radius-facing surface facing it. The radius is approximately concentric with the pivot axis of the lower blade 5 and the locking pin 80 of the upper blade 5 is directed towards the lower blade from the upper blade from.

When winding the roller shutter curtain on the winding shaft 14 (see Fig. 12), two successive fins 5 are pivoted at an angle to each other (see reference numeral α), the locking portion 80 of the upper fin 5 engages with the abutment portion 90 of FIG Lower slat 5, and seen from the winding shaft on the inside of the stopper portion 90. Thus, there is a locking effect against pivoting of the upper fin 5, since the radius withdrawn surface of the stopper portion 90 holds the locking mandrel 80. The shutter curtain 3 can therefore be rolled up reliably and without unwanted pivoting of the pivotable blades 5 on the winding shaft 14. When the roller shutter curtain 3 is extended locking portion 80 and stop portion 90 are unlocked, however, so that the pivoting of the upper plate 5 is released. It should also be pointed out that it would also be possible to provide the tension chain links 19 associated with the non-pivoting slats 5 with corresponding locking and stop lugs.

In the following, the construction of the mechanism for pivoting the pivotable lamellae 5 of the roller shutter curtain 3 described above will now be explained with reference to FIGS. 12, 3, 16 and 17.

FIG. 12 once again shows a schematic view of the roller shutter 2 according to the invention, wherein the winding shaft of the roller shutter 2 is denoted by 14, the drive shaft by 12, the roller shutter curtain by 3 and the end shutter 13 by Aperture of the roller shutter frame. In this case, some of the swiveling slats of the blinds hanging are not shown for reasons of clarity. In this area, however, the roller shutter curtain 3 has the construction shown in FIG. 3 and described above.

Figures 16 and 17 now show a partial sectional view at the height of the line XVI- XVII, wherein in addition to the already shown in Figure 3 shutter loading section with the pivotable blades 5, the pivot levers 59 and the Zugkettengliedern 19 also omitted in Figure 12 side frame 9 of RoII- loading 2, as well as therein a lateral guide rail 34 for actuating the pivot lever 59 is shown.

FIG. 16 shows a closed position of the roller shutter curtain 3, whereas FIG. 17 shows a jaloused position of the roller shutter curtain. In both views, the representation of the lamellar profile was dispensed with, so that the insertion piece marked 64 can be seen in the opened and unfolded position of the lamella, not shown. At the Einsteckstück the hinge pin portion 54 connects, which is passed through a hinge eye between two links of the pull chain, while the support member 20 of extending into the leaf level Zugkettenglieds with its around the pin around the connecting portion 30 can be seen and the drain part 10 of out of the leaf level Zugkettenglieds. In the normal direction N to the roller shutter curtain surface above and below the pull chain, there are two stop surfaces 57, 58 which delimit a guide gap in which the pull chain is guided in the extension direction R of the roller shutter.

As can be seen from Figure 16, in which the position is shown at not aufjalousierter, but not strained lamella, the pull chain lies here with the sliding part of sliding plastic existing part 10 of the Zugkettenglieder on the lower stop surface 57, whereas the upper stop surface 58 out there is a game. In the position of the slats shown in FIG. 17, however, the pull chain rests against the upper stop surface 58 of the side frame 9 with the support parts 20 of the tension chain links and has a play against the lower stop surface 57. In this case, the abutment surfaces 57, 58 are each formed on a plastic part 57, 58 which has been pulled over a web of the side frame profile 9, so that the pull chain is guided largely without friction as long as the roller shutter is opened or lowered and wear of, for example, out of Aluminum existing side frame profile 9 is avoided. On the opposite side of the Einsteckstück 64 of the hinge pin 54 includes a crank portion 53, to which in turn an attack bolt portion 55 axially parallel to the hinge pin 54 eccentrically connected. The engagement bolt 55 protrudes into an installation space 56 provided in the side frame profile 9, in which a side guide rail 34 is arranged, by means of which the engagement portion 55 can be displaced upwards or downwards in the normal direction N to the roller shutter curtain surface, so that the associated lamella via the insertion piece 64 can the hinge pin portion 54, the crank portion 53 and the attack portion 55 and the side guide rail 34 actuate, the stop surfaces 57,58 serve as Zugkettenfixierung so that the pull chain remains substantially in position when the guide rail 34 is actuated , The side guide rail 34 extends parallel to the pull chain and the roller shutter curtain 3 along the extension direction R of the roller shutter curtain and has guide pin 35, in the example shown on the attack bolt 55 opposite side of the side guide rail 34. About the guide pin 35, in turn, the guide rail 34 is actuated , so that all attack bolts 55 and pivot lever 59 and thus all pivotable slats are actuated when the guide rail 34 is displaced altogether up or down. For this purpose, provided on the guide rail 2 guide pin 35 are guided in each case in a control piece formed in a gate channel groove, the movement of the guide rail 34 in the normal direction N imprinting a defined by their course movement pattern. In the figure, 16 and 17, the gate piece has been intentionally not shown for reasons of clarity.

However, such a link piece is shown in FIG 14 can be seen. The gate piece is designated by 24 and the control channel slot by 25. In this case, the gur 14 is an exploded view showing the sliding block 24 before insertion into the installation space 56 of the side frame profile 9. For this purpose, the side frame profile 9 in its bottom wall has a through hole 29 b through which a bolt designated 26 can be inserted and pushed into a bolt receptacle 29 a provided on the piece of rubber 24 in order to fix the sliding piece in the side frame 9 , On the other hand, the link piece, however, via springs 27, which are mounted in corresponding compression spring receptacles 28 on the link piece, resiliently supported against the top wall of the side frame profile 9. In this way it is possible to compensate for tolerances which are provided in order to facilitate the assembly of the link piece 24 in the side frame profile 9. This means that a clearly defined closing force is used to lock the swiveling slats 5, as will be explained below. The Steuerkanalnut 25 in this case has a substantially extending in Rollladenbehangausfahrrichtung R course parallel to the two stop surfaces 57, 58. Offset to the Steuerkanalnut 25, but with synchronous course is still another, generally designated 45, to the front of the gate piece 24 out open cam 45 and a groove, which serves to guide a front side of the side rail 34 attached to the return bar.

FIG. 15 shows a perspective view of the lateral guide rail with the return bar 44 attached to its end face facing its winding shaft 14. The return latch 44 is fork-shaped, its fork opening being designated by 47 and a stop located at the upper end of the rear fork leg by 37. The return latch 44 is furthermore articulated to the side guide rail via a return bolt pivot pin 48. In this case, a guide pin designated by 46 of the return bar 44 is located on the opposite side of the coupling point 48 as the fork opening 47. The return bar guide pin 46 serves to guided in synchronism with the guide pieces 24 distributed in the control channel grooves 25 along the side frame profile 9 In the illustrated embodiment, only two link pieces along the side frame are provided, in each of which one of the guide pin 35th is guided, so that the entire guide rail 34 is always guided parallel to the roller shutter hanging surface. The guide pin 35 in this case has a bolt 38 screwed to the guide rail 34 with a screw 39.

The entire, provided for pivoting the pivotable blinds 5 assembly in the assembled state is shown in Figure 13, which shows the area designated XIII in Figure 12 in an enlarged view. By rotationally driving the drive shaft 12, the pull chain 16 is driven via the peripheral toothed cams 15 of the drive shaft 12 and the recesses 18 associated with the toothed cams 15 in the draw chain links 17, 19 in or against the extension direction R, whereby the entire roller shutter hanging 3 is pushed onto the winding shaft 14. or handled by her. In Rollladenausfahrrichtung R below the drive shaft 12 is responsible for the pivotal movement of the slats 5 assembly consisting on the one hand from the not shown in Figure 13 side frame profile 9 link piece 24 with the Steuerkanalnut 25 as a Schwenkbewirkungs- or -Auslöseanordnung and on the other from the over the guided in the guide pin 25 in the Steuerkanalnut guide rail 34 in which the pivot pins (not visible in Figure 13) are guided, arranged. On the drive shaft 12 associated, frontal end of the side guide rail 34 is the return latch 44 with the pivot point 48 and the Rückholriegel guide pin 46. If the shutter curtain 3 is further lowered from the illustrated position down, the driver 36 moves to the Return latch 44 to.

The driver 36 is attached to one of a non-pivoting blade 6 associated Zugkettenglieder 17, as already in relation to Figure 4, has been addressed.

FIG. 18 shows a side view of the roller shutter 2 with side profile rail 9 (not shown) in a position in which the driver 36 abuts the stop 37 on the return latch 44. Upon further rotation of the drive shaft 12 in the drive direction A of the driver 36 will trigger a torque on the pivot point 48 of the return bar, so that the on the other side of the linkage point 48 Rückholriegel- guide pin in the normal direction N is pressed down and the fork-side part of the return bar 44 upwards.

This position of the shutter 2 can be seen from Figure 19. Upon further driving of the drive shaft 12 in the drive direction A, the roller shutter curtain is moved further into the roller shutter curtain extension direction R, so that the pivot lever

44 is pivoted in the pivoting direction S by the pressure exerted on the driver 36 and thereby on the one hand the driver gets into the fork opening 47 tuned to him and on the other hand the return latch 44 is pivoted so far that the driver 36 abuts against the end face of the guide rail. On the way from the position shown in FIG. 18 into the position shown in FIG. 19, a drive power of the drive shaft 12 has been converted via the point of articulation 48 into a pivoting of the return bar, not in a power acting in roller shutter extension direction, so that the return bar -Führungszapfen 46 has moved to the fixed gate piece 24 out and there at a sliding edge portion of the Rückholriegel-control groove or - control curve 45 connects. The sliding edge portion of the return bar cam

45 has a directional component in the normal direction N down, so that the return latch 44 is pivoted more and more, while the driver 36 already rests against the front side of the side guide rail and this entraps in roller shutter execution direction R.

In this case, the guide rail 34 is taken along by the driver 36 with further extension of the Rollladenbehancjs, so that the guide rail mounted on the guide rail 35 forcibly must pass through the control channel groove 25, whereby the guide rail in its height in the normal direction according to the predetermined by the course of Führungskanalnut 25 Moving profile is adjusted while the roller shutter curtain 3 extends and also during the withdrawal of the roller shutter 3. Here, the Rückholriegel guide pin 46 passes through a Steuerkanalnut 25 corresponding to the course synchronous groove after he slid down along the sliding edge portion and in the frontal inlet opening of the groove portion of the control cam 45 has occurred. After the roller shutter curtain 3 has been moved further along the path designated by ZB, the guide spigot 35 and thus also the Rückholriegel 46 and the guide rail 34 at the lowest point along the Steuerkanalführungsnut, as shown in Figure 20. The slats 5 were thereby swung from their originally against each other loose state in a burglar-proof, mutually blocking state. Thus, from the state shown in Figure 16 down and that by one of the translation of the height difference along the section ZB of Steuerkanalnut 25 by means of the pivot lever 59 in a pivot angle corresponding angle.

The area ZB is adjoined by an area ZT of the control channel groove, in which it runs essentially parallel to the roller shutter curtain surface, which acts as a tolerance compensation for drive inaccuracies of the drive shaft 12. Its length is chosen so that 3 ° drive shaft inaccuracy can be tolerated. At this intermediate tolerance range, a further region AB connects, in which the particular louvering of the pivotable lamellae 5 is effected and which has a directional component in the normal direction N upwards. Initially, the control channel groove rises gently and then rises more and more following an exponential course, so that initially only small parts of the feed power transmitted to the guide rail via the driver are converted into a pivoting power, in the further course of the section AB but always higher proportions, so that an initial resistance when swiveling the pivotable lamellae can be overcome.

Finally, FIG. 21 shows the state of the roller shutter curtain 3 with completely pivoted-up lamellae, which is achieved when the guide pin 35 or, in synchronism, the return bar guide pin 46 reaches the highest point in the control channel groove, whereby also the guide rail 34 reaches its highest point during the roller shutter extension movement has reached. At the area AB, in turn, a tolerance range AT connects in order to compensate for the previously mentioned engine inaccuracies can. If now the drive shaft 12 is driven counter to the drive direction A, to wind the roller shutter curtain back onto the winding shaft 14, passes through the guide pin or. the two guide pins 35 and the return bar guide pin 46 again have the course impressed by the control channel groove, namely the area AT, AB, ZT, and ZB until the guide pin has reached its starting position. During this roller shutter retraction counter to the roller shutter extension direction R, the driver 36 is clasped by the return latch 44 and thus pulled along the guide rail 34. Simultaneously with the impact of the guide pin 35 on the drive shaft 12 facing wall of Steuerkanalnut 25 occurs while the Rückholriegel guide pin 46 from the Steuerkanalnut portion of the cam 45, so that the return bar is forcibly pivoted, since the guide rail 34 via the guide pin 35th is prevented from further movement in the direction of the drive shaft 12, so that the return bar finally releases the driver 36 again.

In a further embodiment, the roller shutter has a pull chain made of chain links, as shown in FIG. In this case, the chain link 119 has a support part 120 and a drain part 110, which consists of several individual pieces 110a, 110b, 110c, which are shown in detail in Figures 23 to 26. Functionally equivalent elements were thereby provided with the same reference numerals as in the chain member 19 shown in Figures 7 to 11. In contrast to the manufactured as a casting support member 20 of Figures 7 toM 1, the support member 120 is manufactured as a sheet metal stamped and bent part, wherein first the recesses 18th have been punched out and then before or after bending into the concave shape of the support member 120 which the discharge part 110 projecting projections 121, 122 and 123 have been folded.

Thus, the support member 120 in turn has extending in the drive direction, arranged on both sides of the support member side webs, which are interconnected via cross-linking ribs and the recesses 18 define. Along the side webs protrude from the protrusions 121, along the front and rear cross-connecting ribs, the protrusions 122 and along the middle cross-linking rib, the projections 123. The projections 121, 122, 123 form a socket for the complementary to the support member shaped drain part 110 in a pre-locked state.

During the assembly of the chain link 119, however, the drainage part 110 consisting of the center piece 110a and the two side pieces 110b, 110c is first applied to the support part 120, as shown in FIG. In this preassembled state, the drainage part is supported by its two side parts 110b, 110c at the front and rear of the support part 120, wherein the middle part 110a is placed on the side parts 110b, 110c so that the individual elements 110a, 110b, 110c of the drain part 110 in this Pre-assembled position are supported against each other and only the centerpiece 110a must be held.

The rear side portion 110c is supported via its hinge eye portion 42 on the one hand on the complementary hinge eye portions 40 of the support member 120 and on the other hand via a rounded contact surface 109 against the associated projection 122, as well as not individually shown front side portion 110b on its hinge eye portion of the complementary thereto Hinge eye portion 30 and a corresponding rounded Anlagefäche on the associated projection 122nd

The two side parts 110b, 110c have, at the ends of their side web sections 124 directed towards the middle, end protrusions 107 projecting beyond a shoulder | 08 with a vertical end abutment surface 106. On the middle part 110a, on the other hand, side edges 105 projecting in the transverse direction to the chain drive direction are provided connect front and rear via side pockets 103 and centrally via a centering in the chain drive direction support portion 101 on the main body of the middle piece 110a. In the preassembled position, the end projections 107 are supported in the side pockets 103 and are supported by their end abutment surfaces 108 on the central support section 101. In cooperation with the support of the two side parts 110b, 110c on the support member 120 via the hinge eye portions 30, 40 thus results in a position in which pressure on the center is sufficient to hold the drain part and only additional pressure on the center piece needs to be exerted to latch the drain part 110 onto the support part 120:

By additional pressure on the middle piece 11Oa snaps the multi-piece support member 110 in the above-mentioned, pre-locked position in the socket formed by the projections 121, 122, 123 socket on the support member 120, in which the locking pin the opening 60 on the support member 1120 with its peripheral posts 70 penetrates and engages behind. Thereafter, the expansion dowel 50 fixed to the center piece 110a via the predetermined breaking point indicated at 151 is pushed into the receptacle formed by the circumferential posts 70 so as to finally fix the position of the drain part 110 to the supporting part 120.

Of course, deviations from the variants shown are possible without departing from the spirit of the invention.

Thus, it would be conceivable, for example, to provide the pull chain instead of with chain links in the embodiment with a drain part 110 and a plurality of individual pieces 110a, 110b, 110c with chain links, each having a one-piece drain part with a plurality of individual sections, which are connected to each other, for example via film hinge. In this way, the assembly of the one piece can be applied to the support member drain part could be facilitated without a higher dimensional accuracy of the support member 120 would be necessary, as is the case with the support member 20 for the undivided expiration part 20. *

It would also be conceivable, instead of one or more identically connected control channel groove (s), in each of which a bolt connected to the roller shutter hanging normal direction guide rail guided bolt, - provide a stationary bolt and the control channel with the pivotal movement of the slats predefined course on the side guide rail. It could (n) also be provided instead of the Steuerkanalnut (s) (one) corresponding to the course of Steuerkanalnut arranged control rail (s) on the (one) connected to the movable in roller shutter curtain normal direction side guide (s) carriage (s) is / are , In the context of the invention fall under the word "Steuerkanalnuten" any type of suitable cams or tracks, with which the displacement of the side guide rail and thus on the pivot lever ultimately the pivoting of the slats can be effected.
