Description

Roller blind with adjustable louvers.

The invention relates to a blind roller with adjustable slats according to the preamble of the claim 1.

Roller blinds with adjustable slats They are widespread today. So, for example, the EP330192B1 or PCT / AT94 / 00130 show a roller blind with adjustable louvers that works according to the next principle: a traction chain is attached so articulated with slats or armored bars, loose from each other, of the cloth roller shutter, each blade being joined, on the other side, with an adjustment chain, whose links can be moved or rotated out with respect to the traction chain links in normal direction to the surface of the roller shutter cloth, for example, when the adjustment chain and the chain of traction is still moving in the direction of advance or exit of the cloth of roller blind.

However, the documents mentioned are not it shows how the mechanism of orientation of the slats.

The roller blind, shown in the document WO99 / 41480, also works according to the same principle, but presents a drive mechanism for the mechanism orientation of the slats. The slats of the roller shutter cloth they are joined together by their two front ends with a traction chain, being displaced against each other articulation points of the two traction chains in the slat. This allows the slats to be adjusted by actuating a traction chain with respect to each other. To guide the slats of the Roller blind cloth is provided here a separate mechanism of adjustment. For this purpose, turning levers have been attached on one side. with each blade in a spin-resistant manner and these allow turning the slats around the axis of rotation of the slats. The chain of traction is articulated on the other side with the slats on the shaft of rotation of the slats. To this end, the turning levers present in each case a crank section that protrudes out and which is guided in a guide rail, moving in the normal direction with respect to the surface of the roller blind. For him guide rail movement is provided here a manual lever which is rotatably connected with the guide rail and allows adjustment of guide rail position in direction normal to the surface of the roller blind and, therefore, the orientation position of the slats. The mobile guide rail and the manual lever mechanism are housed in a side frame of The roller blind.

In WO99 / 41480 it is also proposed another embodiment of the louver roller blind adjustable. In this case, a zipper is arranged in the Side frame scrollable up and down. With a manual lever, a cogwheel is engaged, engaged in the zipper. In this way, gear wheels arranged in the lateral ends of the slats, turning or thus oriented the most. However, here the same problems arise from the embodiment with laterally adjustable guide rail and turning levers

The special disadvantage in this case is that the manual lever is necessarily on the same side of the window as the roller blind, if you do not want to modify the construction of the entire window. That is, the roller shutter is operated with difficulty from the outside or has to be installed on the inner side of the window so that the user comfortably has the slat orientation function. This unnecessarily heats the building to be protected by shade, since the sun's rays hit the window's (insulating) glass, without the protection of the shade, and the roller shutter cannot guarantee safety against Stole. Likewise, a corresponding mounting space is required for the roller blind inside the building and, in addition to the rattle when the roller blind is lowered, abrasion wear of the turning levers and their breakage can occur, since the rail of guide can be in the position of orientation of the slats, even when the roller blind is raised. This causes the slats or the swing levers installed here to collide with a conical guide rail entry piece and only then be placed in position. When the roller blind cloth moves back, the slats turn inwards, on the contrary, when they are wound on the winding axis by the weight of the respective slat itself, so that the roller blind can only be installed on vertical surfaces or with a sufficient inclination, being inadequate, for example, for windows of
roof.

European patent application EP0687793A1 shows another roller blind with adjustable slats. In this case, the adjustable slats of the roller shutter cloth they have frontal heels that extend vertically in the closed position of the roller shutter cloth and are guided in a guide groove in the side frame of the roller shutter. The guide groove extends here from top to bottom along the side frame through fixedly arranged pulleys and rotors arranged rotatably. The rotors are arranged  so that the heels on the slats are at the height of the rotors, when the roller blind cloth reaches its lower position. The slats can be rotated in this position only through its side heels and rotors. To this end, the rotors are attached respectively by a turn lever with a common drive bar. In this case, the bar drive must also be arranged in the same side of the window as the roller blind. In addition, a incorrect drive in a position not completely closed The roller shutter cloth can cause serious damage.

In order to solve the disadvantages in roller blinds with adjustable louvers with separate mechanism drive for the orientation of the slats were proposed, by therefore, different solutions to couple the orientation function of the slats with the advance of the roller shutter cloth.

As coupling they have been proposed in multiple occasions drive arrangements, in which a coupling Exit of the roller blind and swivel blinds Adjustable is done by hooks fixedly installed, in the that necessarily engage hooks fixed in the slat when pass by, see, for example, the documents PCT / AT93 / 00105, EP1130212A2, Figure 5, and EP0382172B1.

On the roller blind with adjustable louvers according to document PCT / AT93 / 00105, the respective bar of orientation as well as the assigned traction chain link and of adjustment chain have the same cross section, forming by means of the lick itself the turning lever that allows to rotate the chain of adjustment relatively with respect to the chain of traction. To the lowering the roller blind simultaneously retains the chain setting to start the slat orientation function. This It is made with a roller blind hook or angular piece that appears in figures 35 to 39 of document PCT / AT93 / 00105, which is installed in the adjustment chain, as well as during descent is deployed by a spring or by force of gravity and slides along a fixedly installed hook. To the turn up the roller blind, the angular piece is moves along the hook and is retained by means of the hook when lower the roller shutter cloth again, so that all the slats joined with the adjustment chain are oriented to the position open when continuing to lower the roller shutter cloth.

Document EP1130212A2 shows, by opposite, an insertion element that can be inserted laterally in a slat profile, as well as joining by means of a drill on the outer side with a traction chain and by another drill, on the inner side with an adjustment chain. The cloth roller shutter is guided with the traction chain in vertical guide rails. One of the links in the chain adjustment has in the normal direction to the surface of the cloth roller blind a hook that sticks out as well as that when lowering the roller blind cloth gears with a counter hook, which is rotatably fixed on the rail lateral guide, thus causing the orientation of the slats.

Document EP0382172B1 also shows a roller blind with adjustable slats, in which the movement orientation of the slats is coupled with the movement of Advance of roller blind cloth. In this case, a hook installed in a link chain link moves ahead of a deviable counter hitch arrangement by means of a lever turn, fixedly arranged, but in a rotating manner. During the lowered, the hook slides in front of an oblique surface of the contragancho arrangement pressed against the hook. The orientation of the slats is performed when the link in the chain adjusting gear with the hook in the counter-hook arrangement after turning up and down the blind cloth roller.

However, these provisions have the problem that the forced coupling device is located outside the closed elements of the roller shutter and, for Therefore, they are subject to weather influences. This type construction, in addition to being unstable, require maintenance, be unsightly and need a lot of space due to the outgoing construction, also implies difficult handling or inaccurate, since the roller blind must be raised and lowered several times to start, set and finish the orientation of the lamas and / or a loud rattle is inevitable during the passage through the fixed hook

Other variants developed refer to turning mechanisms, mounted on the side frames of roller blinds with adjustable slats, to orient the slats of the roller shutter cloth, these being also constructed turning mechanisms so that the rotation of the slats is performed by forced coupling with the advance of the blind cloth roller.

Document DE19842502A1 shows, for example, a roller blind cloth with loose slats that are attached by means of a traction chain arranged on the sides of the the most. The swing levers are rotatably inserted to through the drive chain, joined at one end with the slats spin-resistant and guided by the other end of movable way in a guide rail that can be adjusted using a adjustment mechanism in the normal direction to the blind cloth roller. The adjustment mechanism comprises here a power strip drive arranged in the guide rail and movable in the guide rail in the normal direction to the roller shutter cloth by corresponding cams. In this case, a manual lever to operate the adjustment mechanism, but by the another part already shows a coupling of the mechanism of adjustment with the unwinding of the winding shaft. On a pivot of connection arranged in the winding axis a lever arrangement when the winding shaft has performed a turn and the connecting pin passes in front of the arrangement lever In the lever arrangement a cable is installed Bowden that is attached to the rail adjustment mechanism as guide. In this case, during the first rotation of the axis of winding the adjustment mechanism is released, that is, the strip  operating position is placed in the orientation position of the lamas and the new unwound lamas must first be directed by means of a conical area of track towards the side rail guide, which causes a continuous rattling when the turning levers Even when rolling again on the axis of curl problems originate, since the power strip drive can still be found in the position of use.

To avoid continuous opening and closing of the slats when lowering the roller shutter cloth has proposed, on the one hand, a damping element that prevents a closing of the slats after the slats are oriented to the open position In this solution it is difficult to adjust the diameter of the winding shaft to the building opening of so that it is possible to orient the slats also in one position, which completely covers the opening of the building, and not just in one arbitrary position determined by the diameter of the axis of curl On the other hand, a Locking element against a new closure or ratchet of interlocking that interlocks as soon as the guide rail or the drive strip are in the position of orientation of the slats. However, for the separation of interlocking, which should prevent opening and closing permanent, it is necessary to re-raise the blind cloth roller, that is, in case you do not want to orient the slats to the open position or the orientation of the lamas to the open position.

In addition to this, the proposed construction here It is relatively complex and requires maintenance due to coupling of the movement of the winding shaft, which is performed using the Bowden cable, with the orientation of the slats, not being able to avoid a rattle when lowering the blind cloth roller during the first turn of the winding shaft due to the adjustment of the drive strip.

Austrian patent application AT403829B gives learn about another roller blind with adjustable slats with mechanism of orientation of the slats that is integrated in the racks sides of the roller shutter and causing a coupling forced of the orientation movement of the slats with the movement of advance of the roller shutter cloth. Roller blind shown here also presents loose slats to each other and fixed in a traction chain, through which they are inserted from rotating way turning levers that are joined by one side of spin-resistant way with the slats and on the other end are guided in an adjustment chain, by which a turn is made of the turning levers and, therefore, of the slats. In one of the links of the adjustment chain is provided a hook slat orientation, guided on the side frame, for the orientation mechanism of the slats. The orientation hook of slats is directed by an inclined plane of a tongue towards a sliding guide with a receiving channel when the blind is lowered roller. When the roller blind is raised again, the hook of slat orientation hooks into a receiver hook above of the receiving channel, which deflects the turning levers connected with the slat orientation hook by means of the adjustment chain and, by therefore, all the lamas, which are going to be oriented, are oriented to the open position On the contrary, when the blind cloth roller is raised again, after the hook of slat orientation has left the receiving channel, the tongue covers the entrance to the receiver channel of the slide guide. Of this mode, the slat orientation hook enters the link of the adjustment chain in a channel located on the opposite side of the tongue when rising again, by means of which the tongue is pushed back to the initial position as the blind continues to rise roller. The traction chain links and links of the adjustment chain are made here of flexible steel for spring, only drive parts are mounted on it. This obviously guarantees the necessary flexibility of the construction to prevent the roller shutter cloth from orient to the open position when the orientation hook of slats passes through the slat orientation slide.

On the roller blind with adjustable louvers according to EP0023974 a control jaw is provided arranged stationary on both side frames of the roller blind to cause orientation of the slats of the roller blind. For this purpose, the blinds of the blind cloth roller are guided by a traction chain, through the which is guided by a pivot lever, whose external section of Crank is rotatably guided in an adjustment chain. In the upper plank, which is to be oriented, the crank pivot of the swing lever sticks out through the chain fit to enter the side frame of the blind roller, in which the control jaw is next to The adjustment chain. When the roller blind is lowered, this section external crank lever, which acts as a pin of control, collides with an inclined plane of the control jaw and due to this it deviates out in the normal direction to the surface of the roller shutter cloth, so that all slats, which will be oriented to the open position, are oriented to the open position by means of the compound rotating union of the chain Adjusting and turning levers. When you back up the roller shutter cloth, the control pin enters a channel of return that is tilted up and that ends at a vertical passage channel, in which the control pin is guided when the roller blind cloth is in position not open of the slats. From here, the roller blind You can keep going down or up. When getting on, the pin control presses the inclined plane of the control jaw, configured as leaf spring, as well as press these springs of leaves to both sides and continues to move up. Be generates a loud noise, just like when the blind is lowered roller, when the control pin jumps from the plane inclined, passing through the return channel, to a section of the control jaw that runs essentially horizontally. Further, this provision is prone to wear due to solicitation dynamic leaf springs of the inclined plane, since a large load acts on this inclined plane of the control jaw, Made only of spring steel.

To avoid these disadvantages, the document EP0023974 has already proposed an additional turning cam that can press to the side the inclined plane of the control jaw when an adjustment cam, installed on the front side of the cloth roller shutter, below each control pin, passes through in front of the turning cam. In this way the vertical channel, in the that the control pin moves in the unopened position of the slats of the roller shutter cloth, open first when the roller blind cloth. To close it again it has been installed an additional control cam above the control pin in The front side of the roller shutter cloth. Therefore, at continue lowering the roller shutter cloth, the vertical channel by the way it closes first. The roller blind must be returned to raise then until the control pin is located above the inclined plane of the control jaw. When the roller shutter goes down again, the control pin is deflects in the normal direction to the surface of the blind cloth roller, as in the first embodiment. Without However, in this embodiment they are not eliminated either completely the disadvantages mentioned above.

This is also valid for the other form of proposed embodiment in document EP0023974, in which the channel vertical passage is separated by another spring on a track descending and an ascending path, so that the blind cloth roller has to be lowered first until the control pin push the separation spring aside and then the cloth roller shutter has to be raised again until the pin control moves in the ascending path until reaching the pier, which form the inclined plane, and press it to the side, by that the roller blind is oriented to the position open to the back down, as the control pin deviates over the inclined plane of the control jaw.

Of the proposals mentioned for a blind roller with adjustable louvers with a forced coupling of the exit movement of roller blind and cloth turning movement of the adjustable slats, the roller blind according to EP1130212A2 it is in principle the easiest to operate, because to orient the slats to the open position there is only to lower the roller shutter enough and during the climb the orientation of the slats is automatically canceled again. No intermediate traction elements are needed here, because example, to hook certain hooks and hooks.

However, in this case a sudden closing of the slats oriented in the open position, if the roller blind cloth is lowered so much that the lever position, in which the slat orientation lever still retains the slats oriented in the open position.

Document EP0189091B1 also shows a roller blind with adjustable louvers for facade windows, which, during the unwinding of the roller blind cloth, guides the slats to the open position, completely covering the roller shutter opening, to be protected with shade, when start the orientation of the slats to the open position and being essentially extended completely at the end of the orientation to the open position. The orientation of the slats to the open position works here by a deviation from the force of gravity generated by the weight of the blind cloth roll up arranged vertically. In addition to the traction chain, by which the slats of the cloth are lowered, the roller blind it presents a folding chain, joined with a base support that is in turn rotatably mounted around a pin in a base profile (lower slat of the roller blind), being able to slide the pin in a slot. This also provided a third chain with grooved chain links, being provided in the cam chain grooved links of sliding and in the slats, directed sliding surfaces  towards the sliding cams. By supporting the base profile on the window molding, the base support opens and transmits this movement to the folding chain. To reinforce this, the respective slat is deflected by the stop arrangement formed by sliding cam / sliding surface.

The final opening position is reached at the roller blind cloth fully extended, thus guaranteeing a predefined protection against driving incorrect. No intermediate traction elements are needed here, for example, to engage in certain provisions of contragancho, in order to start the orientation movement to The open position. Even when the blind is rolled again roller with slats oriented in the open position is sufficient move the roller shutter against the exit direction, no need for certain traction elements to perform the disengaged from a contragancho provision. However, in this construction is only possible the orientation of the slats to the open position under certain constructive premises. So by For example, there should be a window molding, on which you can Support the bottom plank. In addition, the force of gravity must be what large enough for the blind cloth to come down roller already causes the orientation of the slats to the position open

Starting from this, the present invention has the objective of creating a roller blind with adjustable slats that has a stable construction, without much need maintenance, as well as enable operation with little wear depending on different characteristics constructive

This goal is achieved with the characteristics of claim 1.

In this case, the louver roller blind adjustable has a roller blind cloth, composed of slats that can rotate, at least in part, around an axis of turn that runs in the longitudinal direction of the slats, a arrangement for carrying out the turn in order to transmit a rotational power to rotating blades and an arrangement of spin initiation in order to generate the spin power for an orientation to the open position, coupled to the position of the roller blind, automatic and simultaneous, of all rotating slats by means of the rotation arrangement during the unwinding of the roller shutter cloth, as well as for orientation to the closed position during winding. TO such effect, the rotation initiation arrangement is configured according to the invention so that during unwinding it is generated and a turning power is transmitted for the orientation of the slats to the open position and during winding, a turning power for the orientation of the slats to the closed position, generating and transmitting the turning power while a point predefined roller blind cloth is in a predefined section of slat orientation that extends into the Departure address In front of the slat orientation section a blocking section is connected, in which during the unwind is generated and a turning power is transmitted for a closing-locking turn to a position, in which the slats are held against each other, and during winding of the roller shutter cloth, a turning power for a turn opening-unlocking to an initial position with lamas loose with each other. In front of the blocking section is connected a feed section, in which the blind cloth roller assumes the initial position with loose slats to each other, in which does not generate or transmit a turning power.

This allows the blind cloth to be lowered first Rolling with loose slats to each other, so that the slats are move against each other during winding and unwinding of the shaft of winding and during the exit of the blind cloth Roll-up does not produce unnecessary tensions, directed a towards another, which would cause early wear of the cloth roller blind due to dynamic solicitation. Upon arriving at the blocking section, the slats are closed successively until finalize the blocking section, thus holding against each other. In a state, in which the roller shutter cloth covers completely the opening to be protected with shade, it gets a position, in which the slats are held against other and therefore guarantee security against theft.

In this case it is advantageous that the provision of Turn initiation is set so that during the Unrolled roller blind cloth is generated and transmits a turning power for the orientation of the slats to the open position and during winding, a turning power for the orientation of the slats to the closed position, which increases with the roller shutter cloth that advances in the direction of exit. Due to the mechanical or constructive particularities, for example, the mutual rubbing of the slats to be opened or similar, there is an initial resistance against the orientation of the slats to the open position, which is more easily removed if the turning power is first applied slowly and increases with the time, especially if it increases constantly. In this case it has advantageous result as increase development a development exponential increase in turning power. The power of spin is generated and transmitted here while a point predefined roller blind cloth is in a predefined section of slat orientation that extends into the Departure address

Other advantageous variants refer to a frictionless roller shutter exit movement if possible, as well as to the application of tolerances to reduce the requirements relating to the precision of the motor control or the manual operation of the roller blind.

When the arrangement of spin initiation so that following the section of slat orientation is connected a terminal section of tolerance that extends to the position completely extended roller blind cloth and in which it is constant the transmitted rotational power, the assembly of a expensive servo motor with precise operation as a drive for roll up or unwind the roller blind cloth or measures similar, since with simpler and cheaper drives also guarantees that, despite the tolerance of the engine, reach the extended position reliably, essentially by complete, of the roller blind, that is, the blind Roller is completely oriented to the open position in each case. This is also valid for manual operation of the roller blind and, therefore, that presents a precision limited

Regarding one more realization and control simple drive and higher position tolerances, associated with this, of the desired position of the blind cloth roller can also be advantageous in addition to an intermediate section of tolerance that is arranged between the blocking section and the slat orientation section and in which the transmitted turning power, as explained above in relationship with the tolerance terminal section.

The spin initiation arrangement can be made, for example, by electromagnets or sliding of piston operated by electromagnet that rotate the adjustable slats in the normal direction to the surface of the roller blind, when a predefined point of the roller shutter cloth with a corresponding signaling element reaches a position predefined during the exit of the roller blind cloth or the Roller shutter cloth inlet. As an element of signaling can be provided here for example a contact slider

However, in relation to a construction economical and simple an initiation provision is advantageous of the spin that breaks down the power, which causes the winding or unwinding of the roller shutter cloth, in a component of feed power and a turning power component, so that the spin initiation arrangement does not need a supply own power or own engine, especially a coupling forced mechanic of predefined blind cloth positions roller with assigned orientation positions of the slats of the roller blind cloth. Therefore, the roller blind is it can operate only with a motor drive or completely with the hand by a simple descent or ascent. As provision of Start of rotation can be used here different gears that break down the power, which causes the winding and unwinding of the roller shutter cloth, in a corresponding power of forward and turn when the respective position of the cloth is reached roller blind.

To objectively transform this generation and desired transmission of the turning power in the section predefined slat orientation, which extends in the direction of output, the arrangement of realization of the turn presents preferably a turning section, joined with all the slats rotating, and an action section, operable by the arrangement of rotation initiation and joined with the rotation section, and the rotation initiation arrangement has at least one slot fixed channel control extending in the direction of exit of the roller shutter cloth and in which the section is guided performance. Thus, a 1: n transmission ratio of one curvature of the control channel groove achieves a position of orientation of all slats, that is, what components of direction of the control channel slot, which run in normal direction to the surface of the roller blind cloth, it transform into a spin of the rotating slats. In a section predefined that extends in the exit direction, that is, the slot of control channel corresponding to the orientation section of the slats, the control channel slot has for this purpose a address component that runs in the normal direction to the surface of the roller shutter cloth and corresponding to the orientation movement of the slats to the open position.

The control channel slot may present also a section corresponding to the blocking section, which presents a direction component in the normal direction, which runs in a normal direction to the surface of the blind cloth roller and corresponding to the turning movement of lock-lock, as well as being placed before the section that corresponds to the orientation section of the slats. The Control channel slot starts here on the shaft side of rolling up the roller blind at a height, seen in normal direction to the surface of the roller shutter cloth, which corresponds to the advance section or the initial position of the slats when extending the roller blind cloth and that runs only in the direction of exit until the section that corresponds to the blocking section.

As objective transformation of the section tolerance terminal may also be provided a section of the control channel slot that runs only in the direction of exit of the roller shutter cloth and which is located at continuation of the section of the control channel slot that corresponds to the orientation section of the slats.

At the intermediate tolerance section you can be assigned a control channel slot section that is located between the section of the control channel slot, assigned to the blocking section, and the channel slot section control corresponding to the orientation section of the the most.

It is also advantageous that the component of direction increase in direction of departure constantly and with exponentially in the normal direction to the cloth roller shutter in the groove section of the control channel which corresponds to the orientation section of the slats.

Therefore, the roller blind according to the invention requires only a control with a simple embodiment of so that it is also suitable for a motor drive of the winding and unwinding of the roller shutter cloth. He Engine control can have a very simple construction here. It is sufficient that the user can connect the motor and disconnect the motor at each desired position of the blind cloth roller, as well as provide for a motor disconnection upon reaching The position of the roller shutter cloth. It is not necessary to arrangement of intermediate traction elements in the control of engine.

Instead of a control channel slot or multiple synchronized control channel slots, in which or in which is respectively guided by the performance section of the rotation arrangement, can also be provided a control lane, in which the acting section is guided. In the context of the invention any other would also be possible. type of suitable control cams.

The roller shutter cloth can be operated here by a traction chain installed, for example, in the front side of the slats or by two traction chains installed on the two front sides of the slats. This one is guided advantageously in the exit direction, especially by means of the or traction chains The control channel slot of the rotation initiation arrangement may be arranged in the side of the drive chain or on both sides of the cloth roller shutter can be arranged a groove channel control that presents in each case a synchronous development with each other. Each of the control channel slots is configured advantageously in a fixed piece of slide that can be housed in a side frame of the roller shutter, so that an actuation of the rotation arrangement, which It is done using the control channel slot, it can take place inside the side frame and therefore protected in a closed housing towards the surroundings.

The side frame advantageously has two stop surfaces that run parallel to the surface of the roller blind cloth, which are located above and above under the drive chain in the normal direction to the surface of the roller shutter cloth and thus delimit a slit of guide, in which the drive chain is guided, especially Loosely The stop surfaces may be covered with a low slip friction material, for example of plastic, in order to keep the power necessary for the exit roller shutter. However, it would be possible too a roller bearing, for example, with cage rails flat.

Through the guide groove, formed by the two stop surfaces, the traction chain is fixed and, by Both, all the roller blind cloth during winding and unrolled at a height set in the normal direction to the surface of the roller shutter cloth. In this way, the entrance of the pull chain of the roller blind cloth or the lower chain link in the guide groove during the unrolled the roller blind, which is rolled completely, it can be carried out accurately and without rattling, since the two stop surfaces are provided in the fixed side frame and, therefore, at a fixed height.

The turning arrangement may present a turn section configured as a chain of adjustment, presenting the links of the adjustment chain in each case a section that rotates an assigned slat. In this case, the actuation section may be formed by a bolt of gear that acts at least one link in the adjustment chain and which is guided in the control channel slot, for example, a gear bolt fixedly connected to the chain link adjustment. This provision allows transmitting with a 1: n ratio execution of the slat orientation and blocking movement, predefined by the control channel slot sections described above, to all the slats to be turned. In this case, the adjustment chain can also be arranged on the side front, next to the slats, and together with the channel groove of control, on the side arms of the roller shutter, of so that a completely closed turning mechanism of The roller blind.

In another perfected embodiment of the invention, the arrangement for carrying out the rotation presents, without However, for each rotating blade a turning lever that has a joint bolt that is tightly attached to the turn with the plank, which is aligned with its axis of rotation and which is guided in turn outwards, in the longitudinal direction of the slat, through a through hole in the drive chain, aligned also with the axis of rotation. To the joint bolt it is connected from eccentric way using a crank or a crank section a guided acting bolt on a guide side rail that runs in the direction of exit. Therefore, the swing lever is configured in the form of a single piece from the bolt of Joint, crank and acting bolt. Side rail guide also has at least one guide pivot, with preferably two pivots that are respectively housed mobile in a control channel slot. Articulation bolts they form here the turning section of the embodiment of the turn and side guide rail with acting bolts and with The at least one guide pivot forms the actuation section. In the configuration with two guide pivots in the lateral guide rail, which are respectively housed mobile in a slot own control channel, it is understood that the guide rails are arranged so that the guide pivots can move synchronously with each other, for example, displaced by translation one respect another. That is, the two channel slots of control have the same development and all guide pivots are they have to find in each moment in the same position in the respective control channel slot to cause movement unified guide rail and therefore a unified movement of all the slats, which are to be rotated, by means of the rotation lever guided in the guide rail.

This advantageous variant of the invention allows, without the need for an additional adjustment chain and therefore through a construction little prone to failures and little maintenance, transmit with a 1: n development relationship, defined by the sections described above, of the channel slots of control to all the slats that are going to turn.

It is advantageous to operate the slats by the guide rails / control channel slots that are provided for both sides of the roller shutter cloth.

The guide rail can be moved, guided by the guide pivots, in the exit direction of the blind cloth roller in the two control channel slots, configured in each case in a separate piece of slide fixedly arranged inside the side frame, and make adjustments in height predefined by the sections described above the slots of control channel

For the movement of the guide rail or of the two guide rails, arranged on the side of the cloth roller blind, a device of respectively lateral guide feed as an element of the arrangement of spin initiation. The side rail advancement device of guide is constructed so that the guide rail advances along of the development of the control channel slot after reaching a initial point established during the exit of the blind cloth roller. A recoil device may also be provided. of the lateral guide rail as an element of the arrangement of rotation start to reverse the guide side rail to the initial position. The rail recoil device side guide is constructed so that this side rail of guide backs along the development of the channel groove of control during winding of the roller shutter cloth until reach the starting point.

The side rail advancement device of guide may be provided, for example, as a stop, provided in the guide rail, for the lower bolt of the bolts acting, so that the lower acting bolt drags necessarily the guide rail, if during the exit of the cloth roller blind this one hits the top. Alternatively to this can be provided for the guide side rail a lateral guide rail drive device, arranged in the side of the roller shutter cloth, must also present the lateral guide rail a stop against the direction of output, which must be adapted, however, for the device of drag of the lateral guide rail on the blind cloth roller, so that the side guide rail performs the Desired path along the development of the channel groove of control. The lateral guide rail drive device it can be configured, for example, as an insert which is inserted in the front side of the blind cloth Rollable in a section above the rotating slats, especially in a chain link traction chain traction, which is attached to one of the first slats not swivels located next to the swivel blades. The top in the guide side rail it can be simply set by the front side of the guide rail directed towards the shaft of curl When the roller shutter comes out, the guide rail it is dragged, if the turning levers of all the slats Swivels are located in the guide rail in the folded state and can be oriented to the open position.

As a side rail recoil device guide can be configured a pretension spring that press down the side guide rail and press the rail guide up against the force applied by the device drag, so that the guide rail travels along the development of the control channel slot up, that is, towards the winding axis, when the blind goes back roller. Theoretically, a rail adjustment would also be possible guide, synchronized with the movement of the blind cloth roller, using magnetic valve plunger slides or Similary.

To design the construction of the device recoil simply and with little maintenance results advantageous that the guide side rail recoil device comprise a recoil pin that is provided in the lane guide side and holding a pin drive device recoil, arranged on the side of the blind cloth roller, when the roller blind cloth comes out and releases it to the rewind the roller shutter cloth, if it has been reached the desired point on the line in the direction of exit of the roller blind cloth. The pin drag device of recoil can be advantageously at the same time the device of Drag the side guide rail, if the stop for the device Drag of the lateral guide rail is provided on the pin recoil, that is, if the recoil pin is provided in the front side of the lateral guide rail directed towards the axis of Rolling up roller blind.

In order to hold the dragging device, the recoil pin is pivotally articulated in the side guide rail, so that the drive device causes a turning moment in the recoil pin when it collides with the eccentric stop and the recoil pin rotates so that with a corresponding section gears behind in the drag device. For this purpose, the recoil pin is advantageously configured as a recoil fork, whose fork hole is first angled towards the trailing device of the recoil pin, being set the stop on one of the fork sides above the fork hole. When the dragging device of the recoil pin, the recoil fork rotates in such a way that one of the fork sides meshes behind in the drag device, while the other side of fork, by on the contrary, it transmits to the lateral guide rail the force transmitted by means of the pin drive device recoil when the roller blind continues to come out, so that it moves down, that is, from the axis of curl, during the exit of the roller blind. He recoil pin could be held in this position, by example, with a spring, until the guide rail stops by its pivot or its guide pivots with the end of the guide channel groove when the roller shutter cloth moves back and the drag device transmits the force necessary to turn the recoil pin back.

In a sliding part also arranged fixed way with respect to the roller shutter cloth, preferably  on a sliding part fixed on the side frame, it is preferably provided a pin control cam of recoil, along which a guide pivot is guided recoil pin, provided in the recoil pin, at Remove and rewind the roller shutter cloth.

The recoil pin control cam can present here a section of sliding edges and a section of groove, as well as being adjusted so that the guide pivot of recoil pin is pressed against the edge section of sliding during the exit of the roller shutter cloth. The Sliding edge section presents a component in normal direction to the surface of the roller shutter cloth, so that a rotating movement of the recoil pin, when the pin guide pivot of recoil is arranged in the recoil pin outside the stop lever line to the pivot point of the recoil pin and it slides along the section of sliding edges. By the component of the section of sliding edges in Exit direction of roller blind cloth is allowed also at the same time a movement of the lateral guide rail in exit direction of roller blind cloth, so that by turning the recoil pin inward around the trailing device of the recoil pin must not be feared a blockage of the exit movement of the blind cloth roller. The recoil pin control cam also has a groove section that is located after the section of sliding edges in the direction of exit of the cloth roller blind and has the same development as the groove or the guide channel slots, moving the guide pivot of recoil pin in the groove section synchronously to guide pivot or guide pivots in the groove or grooves of the guide channel.

Another advantageous variant of the blind roller according to the invention refers to a motor drive of  the roller blind, which is advantageously installed on a shaft drive, separated from the winding shaft and provided with toothed cams in the circumference, by means of which the axis of drive can act on the roller blind cloth that is It will move. If the traction chain is made up of links individual traction chain joined together so articulated at least in the area of the rotating slats, as well as joined in each case with the slats of the roller shutter cloth, may be provided in the traction chain links respectively one or several notches assigned to the cams toothed the drive shaft, so that the drive is You can perform with the traction chain. For the engines conventional drive has proved appropriate that the length of the tolerance terminal section or section assigned to the tolerance terminal section in the channel slot control, as well as the intermediate tolerance section or the section assigned to the intermediate tolerance section in the groove of control channel equals a motor precision with angle of drive shaft +/- 3º.

The traction chain links, if they are assigned to a rotating slat, they can be attached to the slat using the assigned pivot lever articulation bolt, the articulation bolt is guided through a hole in joint that links two traction chain links together articulated way. The swing lever can be connected to the blade swivel assigned by an insert that connects to its articulation bolt, if this blade is composed of a profile open on the front side, in which the piece of insertion.

If the traction chain link is assigned, on the contrary, to a non-rotating blade, may be planned a traction chain link construction that It has an insert that connects on the side of the lama to the traction chain link and with which the link of traction chain is inserted directly into the respective the MA. Regarding a solid manufacturing of the slats it is advantageous that all the slats, whether rotating or not, are made of the same open profile on the front side, for example, of a plastic or aluminum profile. Lama's profile can present advantageously an upper groove of the weatherstripping in the direction of exit of the roller shutter cloth and a lower groove of weatherstrip open respectively to the front side, where they can insert rubber profiles that seal the space intermediate between the slats in the non-oriented state. Lamas no swivels can be attached to the slats, which are connected respectively above / below, by joining profiles of rubber inserted in its grooves, presenting the profile rubber bonding in the cross section approximately the shape of a stylized bone or a figure in eight. Lamas adjustable can present respectively, on the contrary, in its lower weatherstrip grooves a rubber sealing profile which in the cross section has approximately the shape of a Tadpole and is joined only with a lama. In the state of lamas not oriented to the open position, the shutter profile of rubber visually seals the intermediate space between two slats successive, while successive slats, on the other hand, are they can separate from each other when they are oriented to the position open

For an anti-theft blind configuration roller is advantageous in addition to the lower end of the roller blind blind cloth band is provided a protector of closure than in the fully extended position of the cloth roller shutter covers at least the bottom plank, at least partial way, and the bottom plank cannot turn. In position of the roller shutter cloth (in the locked position), which completely covers the opening to be protected with shade, it prevents, additionally, that the roller blind is back up from below.

Other advantageous variants are subject to Other secondary claims.

The individual characteristics of the forms according to the claims can be combined with Any reasonable way.

Reference is first made to Figure 1, in the which is shown a roller blind 1 installed in a roof window 2.

The roof window 2 has a glass, framed in a window sheet 10 that is arranged in a frame of window, whereby the roof window 2 is fixed in the roof of a building, covering its building opening.

The roller blind 1 has a cloth 3 of roller blind with adjustable louvers, as well as a fence roller blind cloth 3 which is formed by a drawer 4 of roller shutter, side frame profiles 9 and a protector 13, with the lateral frame profiles 9 being joined by connecting inserts 11, provided at their ends, with the closure guard 13 (see figures 1b and 1c) and being inserted these by their other ends in housings Corresponding drawer 4 roller shutter.

The roller blind 1 is represented here with fully extended roller blind cloth 3 and oriented to the open position. The roller shutter cloth 3 It has a section with adjustable or rotating slats 5, which protects with shade most of the roof window 2, and a section, located on the side of the winding shaft, with non-rotating slats 6. The roller shutter cloth 3 also has a lower slat non-rotating 66 that is lowered to below closure protector 13.

The roller shutter 1 is mounted by the exterior over roof window 2 so that window 2 of roof can continue to open, that is, in such a way that the user can open window sheet 100 in the direction A spin in the attic room.

Figure 1b shows roller blind 1 and the roof window 2 in the fully open position of the window. It is noted that the window sheet 100 is housed in articulated way about halfway up in the window frame 7, so that its lower half opens towards outside, while its upper half is turned inwards to window 2 is opened. Roller blind 1 is screwed on the side of the roller shutter drawer 4, respectively by a fastening plate 112 articulated frontally in the drawer 4, with the two side slats of the window frame 7. In addition, the two profiles 9 of side frame of roller shutter 1 se can displace and are articulated together with the section from window 2 open outwards, namely in the area of both lower corners of the window sheet 100, as explained in detail below based on figure 1d.

Figure 1d shows a section in the area of one of the two corners of the window sheet 100. One piece angular 131 is fixed here on the window sheet 100 which is guided by a window guide roller 135 in a section 133 of window guide rail of side frame profile 9 of roller shutter 1. Side frame profile 9 serves to at the same time as a guide of the roller shutter cloth 3, being housed also the slat orientation mechanism for the function of orientation of the slats of the roller shutter cloth 3 at least largely on side frame profile 9, as explained later on the basis of figures 16 and 17.

Figure 1c shows the roller blind 4 installed on roof window 2 in a position of ventilation, in which it is automatically fastened with the help of a spring, when compensating the weight of the roller blind that acts against the opening direction A by force elastic acting in the opening direction A. In figures 1b and 1c it can be seen that the window sheet 100 performs a essentially greater rotational movement than the roller blind 3, because the lever arm from the point of articulation of the window sheet 100 in window frame 7 to roller 135 of guide in profile 9 of side frame of roller blind 1 it is essentially shorter than the lever arm from the point of suspension of roller shutter drawer 4 up to roller 135 as guide. For this reason, the window sheet 10 must be guided articulated and movable in profile 9 of blind Rollable by guide roller 35.

The roller shutter drawer 4 consists of several individual elements, that is, a lower element, a top cover protector 115 as well as elements sides 116 installed here on the front side, which are covered in turn with the side shields 117 of covering. The roller shutter drawer 4 is connected to the window frame 7 by means of clamping plates 112, articulated on its front sides, the two being housed in a covered manner joints in the side elements 116 of the drawer 4 of roller blind.

In the position represented in Figure 1a, the rotating blades 5 are oriented to the open position of such so that the direct entry of the sun through the window is avoided 2 roof and, therefore, extreme warming, but the view Outward is free for the stylized person. In correspondence with the inclination of the roof, the angle, at which the rotating blades 5 are oriented to the open position, It is approximately 30º. The maximum angle of orientation to the open position can be set, for example, by a corresponding development of a control channel slot, which is Will explain in detail later. This way you can commercialize roller blinds for different angles of inclination of the opening to be protected with shade. Is it is also possible to mount a blind on the roof window 2 roller with a maximum angle of orientation greater than the angle represented by 30º and let the user lower cloth 3 of roller blind only to the open orientation position desired of the swivel blades 5 or adapt the motor control for driving the roller blind, which will be explained also in detail later, to the inclination of the opening that is going to be protected with shade, being in this case the roof slope.

Figure 2 shows in a representation a enlarged scale detail, identified with II in figure 1, or either, a section of the roller blind 3 with slats adjustable 5 and non-adjustable slats 6. Here it is observed that both adjustable slats 5 as non-orientable slats 6 are made of the same curved hollow profile in the form of a wing, in this case, of a hollow plastic profile open on the front side, and present in R direction of exit of the roller shutter cloth, on the side upper and lower, a grooving slot 53 also open in the front side This configuration has, on the one hand, the advantage of a weight-saving construction of the mobile elements of the roller blind cloth. On the other hand, in the holes front 52 of the plastic profile of the slats 5, 6 can be insert construction elements with insert pieces conveniently configured.

In the case of non-rotating slats 6, this It could be a plastic insert to cover the hole 52 of the slat profile or a chain link in a chain of traction, provided with a corresponding insert, as will be explained later. In the case of rotating blades 5, this could be, for example, a turning lever, formed in a corresponding insert, of a turning arrangement for the lama, through which it can be transmitted to the lama rotating 5 a turning power with a steering component in normal direction N to the surface of the roller shutter cloth. In the case of non-rotating slats 6, in slots 53 of weatherstrip can be housed respectively a section of weatherstrip of a joint profile 8 with an approximate bone shape, with preference of a rubber joint profile, whereby the lamas 6 are linked together, so that it is not it is essential to unite them with an additional chain of traction arranged only on one or both front sides of the the most. The rotating slats 5 have, on the contrary, in their lower grooves 53 of weatherstrip inserted profiles 7 of sealing, preferably rubber sealing profiles, of so that they rest respectively on the next plank, directed downwards of the roller shutter cloth 3 and can be orient to the open position by means of a turning power with a component that acts in the normal direction N to the surface of the roller blind cloth.

As derived from Figure 2, the slats swivels 5 of roller shutter cloth 3 must be fixed between yes by means of frontal connection elements, for example, by swing levers that connect to insert parts that are fit holes 52, as well as being guided in a chain adequate traction.

A section is represented in figure 3 Corresponding roller blind cloth with levers Swivel and traction chain inserts.

The turning levers are identified here in general with the number 59 and present an insert piece 64 indicated with dashed lines, with which they are inserted in the front hole 52 (see figure 2) of the slats 5 and close frontally the hollow profile of the slats 5. To the piece 64 of Insert connects a joint bolt section or bolt 54 of articulation protruding from the front side in the direction longitudinal L of the slats and that is guided through a joint hole between two links 19 of a chain 16 of traction. A joint bolt 54 is connected in turn crank section 53 of the swing lever 59, by means of which an actuation section 55 is eccentrically connected with the articulation bolts, so that by applying a force or power on acting bolts or section 55 of performance, the assigned slat 5 can rotate around its axis of turn that runs in the longitudinal direction L of the slats, if the traction chain 16 is supported at the same time in normal direction N a The surface of the roller shutter cloth against the force incident.

Chain traction chain links 16 traction, assigned to the swivel blades 5, are identified here in general with the number 19 and are composed in each case of a support element 20 and a passage element 10, being represented one of these respectively in an exploded manner in the Figure 3. The traction chain links have holes interns 18 running in a normal direction to the surface of the roller blind cloth and that, as explained below, they can be traversed by single axis drive cams receiver to wind and unwind the blind cloth roller. The drive chain is guided in a guide groove between an upper and lower guide surface, as explained also later, through which friction occurs at take off and roll up the roller shutter cloth due to the tilt of the roof window 2 mainly on the side of the lower guide surface.

A traction chain link 19 of this type, assigned to a rotating blade 5, or the support element 20 and the passage element 10 of the traction chain link 19 are shown in detail in figures 7 to 11, to which it is made reference below.

Figures 7, 8 and 10 show the process of assembly of the support element 20 and the passage element 10 for form a final link chain 19. The support element 20 is a metallic element in the form of a single piece, made especially cast iron, and essentially assumes the transmission of force to traction chain 16. Element 10 by the way, on the contrary, it is an overlapping piece of plastic on the support element 20 and serves to reduce the friction of the traction chain 16 that passes over the passage element. To the support element is connected in the longitudinal direction of the chain, on one end, a first binding heel 30 and on the other end, a second heel 40 in the form of a single piece, that form respectively with the other heel 40, 30 of union of the next chain link a joint hole 31, 41 for the articulation bolt 54 (see figure 3) of the assigned lever 59, the bead 40 being configured in the form of fork with a groove-shaped groove for the other heel 30 of connection of the next link 19 of chain.

The basic structure of the support element 20 it is formed here by lateral projections that extend in drive direction, which are arranged on both sides of the support element and linked together by nerves cross-sections, thus defining the notches 18. The bearing surface FL of the support element 20, directed towards the passage element 10, it has highlights 21 that extend to along the lateral projections, as well as highlights 22 that extend along the front transverse nerves and backs of union and that form a fence to fit the element 10 step shaped in a complementary way to the support element. The support element 20 is concavely curved with respect to the bearing surface FL corresponding to the profile of the slats, also presenting the passage element 10 a curvature concave complementary to this.

The support element 20 therefore has a central cap, seen in the direction of operation of the chain, on the side opposite the passage surface, on which it is provided a central transverse junction nerve with a housing central 60. The passage element also presents a construction to from lateral projections in the direction of operation of the chain, which are joined by transverse nerves, extending along the lateral projections and nerves transverse front and rear joining highlights outstanding in the direction of the support element, which are configured so that the step element can be embedded in The support element.

Chain link 19 is shown in the figure 8 in the embedded state, previously mounted. In this case it note that the front and rear transverse junction nerve of the step element 10 or the two outstanding highlights here is connect joint hole sections 32, 42 that complement the joint hole sections 31, 41, configured as a hook, in the support element 20. Be You can also see that an expandable block or pressure block, identified with the number 50, in pre-assembled state of link 19 chain is positioned aligned in front of hole 60, which is shown in detail in figure 9 from the direction of the surface opposite the passage surface.

In this case a retention pin is observed, interlocked in the through groove or retaining hole 60, which it consists of concentrically arranged handling bars 70 and in the form of cylindrical segments. Retaining pin protrudes, in a manner not shown, from the passage element 10 towards the support element 20 in a state aligned with the hole intern 60, the bars 70 of each being provided in each case manipulation in the form of cylindrical segments of a tip of retention, through which they engage behind in the fence of the retention notch, so that the passage element in the preassembled state shown in figure 8 is already embedded in the support element 20. The retention pins are made of material of the passage element 10, that is, of plastic and, therefore, they are elastic, so that they can be interlocked and unlocked with ease.

In order to reliably prevent the unlocking the cylindrical handling bars 70, the expandable block 50 is provided in the passage element, which is connect to the passage element through a controlled break zone aligned with the insertion hole, as you can derive from the unmounted state of figure 7. The break zone controlled can be made, for example, from a union of thin film, configured during injection molding of the passage element, between the expandable block 50 and the element of He passed. When the expandable block 50 is pressed under pressure, such as shows figure 10, in an insertion hole created within the retaining pivot by means of shaped bars 70 of cylindrical segments, efficiently prevents unlocking the handling bars 70 in the form of cylindrical segments, as also derived from figure 11 which shows a plan view from above on an enlarged scale of the surface of the support element, opposite the surface FL of support, in the area of the through hole 60 with the expandable plug 50 introduced under pressure.

Figure 4 shows, on the contrary, a Cloth section 3 of roller blind with non-rotating slats 6. One of the profiles 8 of bone-shaped rubber of dog, by which the lamas 6 are joined together respectively. In this case, the slats 6 are made of it. open profile on the front side of the rotating slats 5 represented in figure 3. In the front profile hole 52 a chain link with its part 65 is inserted respectively of insertion, transmitting the support force in the section of roller blind, composed of non-rotating slats 6, when lowering, rewind and in the lowered position of the blind Rollable by rubber sealing profile 8 and not by the individual links 17 of traction chain which they are planned in this area and they differ from the links 19 pull chain in the blind cloth section roller with rotating slats for not being directly attached each.

The traction chain links 17 are formed of plastic and inserted in the profiles 6 of the slat, following the curvature predefined by the wing-like shape of the profile of lama and presenting, like links 19 of traction chain, in the area of the swivel blades 5 holes 18 for insertion of single-axis drive cams drive The traction chain links 17 have also at its front and rear end in the R direction of exit heels 71, 72 that resemble the hole sections of joint. However, the heels serve on the one hand to join the first chain link 19, assigned to the last strip swivel 5, with the next link 17 of chain assigned to a non-rotating blade 6 and, on the other hand, to be able to insert a insert, described below, of a device lateral guide rail drag and recoil pin, the insert must be inserted only in one of the traction chain links 17, presenting all links 17 traction chain an equal configuration due to the existence of a greater number of pieces and for a unification of The elements. Alternatively, chain links 17 of traction can also be joined together by their heels 71, 72 similar to the joint hole.

Alternatively to the embodiment, shown in figure 4, of the traction chain links 17 non-rotating blades can also be used links two-piece chain with a support element and an element of He passed.

Figures 5 and 6 show a variant of the construction elements formed respectively by lever 59 turning and insert 64 and joined with the rotating blades 5. Figure 6 shows the detail VI of the figure 5.

Figure 5 shows a front side view schematic of the insertion pieces 64 of successive slats 5. The slats have, seen in the direction of departure, a heel 80 in their lower ends and a heel 90 at its upper ends. From facing heels 90, 80 of successive slats 5, heel 80 acts as a blocking section 80 and heel 90, as a stop section for locking section.

It is noted that section 80 of blocking is configured as a locking pin that protrudes from the opposite chain link and stop section 90, as a surface that is directed towards it and that runs with a radio. The radius runs approximately concentrically with respect to the axis of rotation of the lower blade 5 and the pin 80 of upper blade lock 5 protrudes from the upper blade in direction to the lower plank.

Yes, when the roller blind cloth is rolled up on the winding shaft 14 (see figure 12) two slats are turned successive 5 relative to each other at an angle (see reference α), the locking section 80 of the upper blade 5 gears with the upper section 90 of the lower slat 5, namely on the side inside of the stop section 90 seen from the axis of curl In this way a block against an opening is achieved of the upper strip 5, since the surface, receded according to the radius, of the stop section 90 retains the locking pin 80. He roller shutter cloth 3 can then be rolled on the shaft 14 winding reliably and without opening unwanted rotating blades 5. On the contrary, being extended roller shutter cloth 3, lock section 80 and the stop section 90 are unlocked, so that the slat Top 5 can rotate freely. In this sense it should be noted that it would also be possible to provide links 19 of chain traction, assigned to non-rotating slats 5, heels corresponding lock and stop.

The construction of the mechanism for rotating the swivel blades 5 of the cloth 3 of roller blind described above on the basis of figures 12, 3, 16 and 17.

Figure 12 shows a view again schematic of the roller blind 2 according to the invention, in the that the winding axis of the roller blind 2 is identify with the number 14, the drive shaft, with the number 12, the roller shutter cloth, with the number 3 and the protector of closing the roller shutter frame, with the number 13. In in this case some of the rotating slats of the roller blind cloth for better understanding. In this zone, the roller shutter cloth 3 presents the construction represented in figure 3 and explained below.

Figures 16 and 17 show a partial view in cut at the height of line XVI-XVII, being also represented here, in addition to the blind cloth section roller, already represented in figure 3 with rotating blades 5, the swing levers 59 and the traction chain links 19, the side frame 9 of the roller blind 2, removed in the Figure 12, as well as a guide rail 34 located here for actuate the swing lever 59.

Figure 16 shows a closed position of the roller blind cloth 3, while figure 17, by the opposite, it shows an open position of the blind cloth roller. The profile of slats was not represented in both views, so that the insert identified with the number 64 is can observe in the open and closed position of the slat no represented. Section 54 is connected to the insert articulation bolt that is guided through the hole articulation between two links of the traction chain. Here is you can observe the support element 20 of the chain link of traction, which extends into the plane of the blade, with its junction section 30 located around the bolt and the element  10 of the traction chain link protruding from the Leaf plane. In normal direction N to the surface of the cloth roller blind, above and below the chain traction, there are two surfaces 57, 58 butt that delimit a guide groove, in which the chain is guided R-direction traction of the roller blind.

As can be seen in Figure 16, that shows the position of the slat not oriented to the open position or prestressed, the drive chain with the passage element 10, made of sliding plastic, chain links traction rests on the bottom surface 57 of stop, on the contrary, there is a slack in relation to the surface top 58 butt. In the position of the turned slats or oriented to the open position, shown in figure 17, the traction chain makes contact, on the contrary, by means of traction chain link support elements 20 with the upper surface 58 of abutment of the side frame 9 and has a clearance relative to the bottom surface 57 of the stop.

Stop surfaces 57, 58 are configured respectively in a plastic element 57, 58 placed  on a projection of the side frame profile 9, so that the drive chain is largely guided without friction during the descent or rise of the roller blind and wear is avoided of side frame profile 9 manufactured, for example, of aluminum. On the side of the joint bolt 54, opposite the insert piece 64, a crank section 53 is connected, to the which in turn eccentrically connects a section 55 of acting bolt in axial parallel direction with respect to bolt 54 of articulation The actuation bolt 55 enters a space 56 of assembly provided in side frame profile 9 and in which is arranged a lateral guide rail 34, on the that section 55 can be moved up or down acting in normal direction N to the surface of the blind cloth roller, so that the assigned blade can be operated by insertion piece 64, bolt section 54 of articulation, crank section 53, actuation section 55 and side guide rail 34, serving surfaces 57, 58 of stop as traction chain fixation, so that the chain traction remains essentially in position when operated guide rail 34. The guide rail 34 extends in parallel to the drive chain and roller blind cloth 3 along the exit direction R of the blind cloth roller and has guide pivots 35, according to the example represented, on the side rail side 34 of the opposing guide to bolt 55 acting. Using the guide pins 35, in turn drives the guide rail 34, so that they are operated all acting bolts 55 or turning levers 59 and, for therefore, all the rotating slats, when the guide rail 34 is generally moves up or down. To this end, the guide pins 35, provided in the guide rail 2, are guided respectively in a control channel slot, set to a sliding piece, which provides a movement model defined by its development to the movement of the guide rail 34 in normal address N. In figures 16 and 17 it has not been represented intentionally sliding piece for better understanding.

A sliding part of this type can be observe in figure 14. The sliding part is identified here with the number 24 and the control channel slot, with the number 25. Figure 14 is an exploded representation showing the Sliding part 24 before inserting into space 56 of mounting the side frame profile 9. For this purpose, profile 9 side frame has a drill in its bottom wall through 29b, through which a bolt can be inserted identified with the number 26 and insert in a 29th housing of bolt provided on the slide part 24 to fix the piece of sliding on the side frame 9. On the opposite side, the piece of Sliding, on the other hand, rests elastically against the covering wall of side frame profile 9 by 27 pressure springs that are mounted in housings corresponding 28 spring pressure in the slide piece. In this way it is possible to compensate the tolerances planned for facilitate the assembly of the sliding part 24 on the profile 9 of side frame. That is, a closing force is used clearly defined for the lock-close turn of the rotating slats 5, as explained below. Slot 25 control channel has a development, which extends essentially in the R direction of exit of the blind cloth Rollable, parallel to the two surfaces 57, 58 butt. From displaced manner with respect to the control channel slot 25, but with a synchronous development, another cam 45 of control, open towards the front side of the sliding part 24 and identified with the number 45, and a slot that serves to guide a recoil pin installed on the front side of lane 34 as guide.

Figure 15 shows a perspective view side guide rail with recoil pin 44 installed on the front side directed towards the winding shaft 14. He recoil pin 44 has a configuration in the form of fork, its fork hole being identified with the number 47 and a stop located at the upper end of the rear side of fork, with the number 37. The recoil pin 44 is further articulated in the lateral guide rail by means of a bolt 48 of recoil pin articulation. A guide pivot, identified with the number 46, the recoil pin 44 is located on the opposite side of the articulation point 48, like than fork hole 47. The pin guide pin 46 of recoil serves to be guided synchronously with the pieces 24 slides distributed in the slots 25 of control channel a along side frame profile 9, namely in slot 45 of recoil pin guide that is configured in the part front slide 24, view from the winding shaft. In the embodiment shown is provided only two pieces of slide along the side frame, in which it is respectively guided one of the guide pins 35, so that the entire guide rail 34 is always guided parallel to the surface of the roller shutter cloth. The guide pivot 35 features a bearing roller 38 screwed with a bolt threaded 39 in guide rail 34.

The entire construction group, intended to rotate the rotating slats 5, in the assembled state appears in Figure 13 showing the area identified with XIII in Figure 12 in an enlarged representation. When the drive shaft 12 is rotatably operated, the drive chain 16 is driven by toothed cams 15, located on the circumference, of the drive shaft 12 and the housings 18, assigned to the toothed cams 15, in links 17, 19 of traction chain for or against the R direction of exit, thus winding all the roller shutter cloth 3 on the winding shaft 14 or unwinding from it. In the exit direction R of the roller shutter, below the drive shaft 12, the construction group, responsible for the rotating movement of the slats 5, which is composed, on the one hand, of the sliding part 24, arranged is arranged fixedly on the side frame profile 9 not shown in FIG. 13, with the control channel slot 25 as an initiation or release arrangement of the turn and, on the other hand, the guide rail 34 which is guided by the pivot 25 guide in the control channel groove and in which the pivot pivots are guided (not shown in Figure 13). At the front end of the guide rail 34, assigned to the drive shaft 12, is the recoil pin 44 with the articulation point 48 and the pivot pin 46 of the recoil pin. When the roller shutter cloth 3 is
continues to descend from the position shown, the dragging device 36 approaches the recoil pin 44.

The dragging device 36 is inserted here in one of the traction chain links 17 assigned to a non-rotating blade 6, as explained on the basis of the figure Four.

Figure 18 shows a side view of the roller blind 2 with side rail profile 9 not shown  in a position, in which the dragging device 36 collides with the stop 37 on the recoil pin 44. By continuing to rotate the shaft 12 drive in the drive direction A, the dragging device 36 causes a turning point at the point 48 of articulation of the recoil pin, so that the pivot  of recoil pin guide, located on the other side of the point 48 joint, is pressed down in the normal direction N and the element located on the fork side of pin 44 of recoil is pressed up.

This position of roller blind 2 is can be seen in figure 19. When the axis 12 of the drive in drive direction A, the cloth roller shutter continues to move in the R direction of exit of the roller shutter cloth, so that the turning lever 44 rotates in direction S of rotation due to the pressure exerted by the dragging device 36 and the dragging device reaches thus, on the one hand, the fork hole 47 fitted thereto and the drag pin 44 is rotated, on the other hand, until the dragging device 36 collides with the front side of the rail guide. In the path from the position shown in Figure 18 up to the position shown in figure 19, a power of drive shaft drive 12 was transformed by the articulation point 48 in a turn of the recoil pin and not in a power acting in the direction of exit of the blind roller, so that the pin guide pin 46 of recoil has moved towards the fixed slide part 24 and collides here with a section of sliding edges of the groove of control or recoil pin control cam 45. The section of sliding edges of cam 45 pin control recoil presents a direction component in normal direction N down, so that the recoil pin 44 follows rotating while the dragging device 36 makes contact with the front side of the side guide rail and drag it on R direction of exit of the roller shutter.

When the roller shutter cloth is followed extending, the dragging device 36 drags the rail 34 of guide, so that the guide pivots 35, installed in the rail guide, they have to travel through slot 25 of channel control, whereby the guide rail is adjusted in height at normal direction according to the predefined motion profile fixedly by the development of the guide channel groove 25, during the exit of the roller shutter cloth 3 and even during the retraction of the roller shutter cloth 3. In this case, the recoil pin guide pin 46 also travels a slot, which corresponds to the control channel slot 25 and which runs synchronously to its development, after having slipped it down along the section of sliding edges and having entered the hole front of the groove section of the control cam 45. After the roller blind cloth 3 continued to move on the route identified with ZB, the guide pin 35 and, by both, the recoil pin 46, as well as the guide rail 34 are found at the bottom point along the guide groove of control channel, as shown in figure 20. In this way, the slats 5 turned from their original open state with respect to each other to a closed state with respect to another, which is safe against theft, that is, of the state represented in Figure 16 below, namely, at an angular value that corresponds to the transformation into a angle of rotation of the height difference along the section ZB of the control channel slot 25 via the lever 59 of turn.

A ZT zone of the slot is connected to the ZB zone of control channel, in which it runs essentially in parallel to the surface of the roller shutter cloth and acting as tolerance compensation for drive inaccuracies of drive shaft 12. Its length is selected here from so that an inaccuracy of 3º of the axis of drive To this intermediate tolerance zone another one is connected zone AB, in which the actual position orientation is caused open of the rotating slats 5 and which has a component of direction in normal direction N up. The channel slot control increases first gently and ascends more and more, following an exponential development, so that only small parts of the forward power, transmitted by the device 36 drag to guide rail 34, can first be transformed into a turning power, although the percentage is increasing with the further development of section AB, thus being able to overcome a initial resistance when opening the rotating slats.

Figure 21 shows the state of the 3 roller blind cloth with fully open slats, which is reached when the guide pivot 35 or, synchronously to this, the control pin guide pin 46 reaches the point maximum in the control channel slot, so that also the guide rail 34 has reached its peak during the exit movement of the roller shutter. To zone AB is it also connects a tolerance zone AT to compensate for the Engine inaccuracies already mentioned above.

When drive shaft 12 is driven then against drive direction A to return to roll up the roller shutter cloth on shaft 14 of winding, the guide pivot or the two guide pivots 35, as well as the recoil pin guide pivot 46 travels again the development defined by the channel slot of control, that is, the zone AT, AB, ZT, as well as ZB, until the pivot guide has reached its initial position. During this setback of the roller blind against the R direction of exit of the roller blind, the dragging device 36 is held down the recoil pin 44, thus dragging the rail 34 of guide. At the same time as the collision of the guide pivot 35 with the wall of control channel groove 25, directed towards axis 12 actuator, the recoil pin guide pin 46 comes out of the control channel groove section of cam 45 of control, so that the recoil pin rotates forcefully, because guide pivot 35 prevents further movement of the rail 34 guide in direction of drive shaft 12, whereby the recoil pin finally releases device 36 of drag.

In another embodiment, the blind Roller has a traction chain formed from chain links, according to the representation of figure 22. The chain link 119 has a support element 120 and a step element 110 consisting of several individual pieces 110a, 110b, 110c depicted in detail in Figures 23 a 26. Elements of the same functioning were identified here with the same reference numbers as chain link 19 shown in figures 7 to 11. Unlike element 20 of support of figures 7 to 11, manufactured as a molten element, the support element 120 is manufactured as a folded element stamped sheet. First the notches 18 and a then, before or after bending the element 120 of support in the concave mold, highlights 121, 122 and 123 were folded protruding towards the passage element 110.

Therefore, the support element 120 has its side projections that extend in the direction of drive, which are arranged on both sides of the element of support, as well as being linked together by nerves cross joints and delineate the notches 18. Along of the lateral projections, the protrusions 121 stand out, along of the front and rear transverse junction nerves, the projections 122 and along the central transverse junction nerve, Highlights 123. Highlights 121, 122, 123 form a fence for the passage element 110, shaped in a complementary manner to the support element, in a previously locked state.

However, during assembly of link 119 chain, the passage element 110, composed of the centerpiece 110a and of the two side pieces 110b, 110c, it is installed first in the support element 120, as shown in figure 12. In this pre-assembled state, the step element is supported, by its two side elements 110b, 110c, in the support element 120 by front and rear, with the centerpiece 110a mounted on the side elements 110b, 110c so that the elements individual 110a, 110b, 110c of the passage element 110 remain leaning against each other in this pre-assembled position and only hold the centerpiece 110a.

The rear side element 110c is supported, by one side, through its joint hole section 42 in the complementary sections 40 of articulation hole support element 120 and, on the other hand, by means of a round surface 109 of contact, in assigned shoulder 122. Also, the side element 110b, not shown in detail, is supports through its joint hole section in the section 30 joint hole, complementary to it, and a corresponding round contact surface, on the shoulder assigned 122.

The two side elements 110b, 110c have in the ends of its lateral protrusion sections 124, directed toward the center, extreme protrusions 107 protruding respectively of a shoulder 108 with a vertical surface Extreme 106 contact. In the centerpiece 110a are provided, on the contrary, lateral edges 105 projecting in the direction transversal with respect to the chain drive direction and which are connected to the base body of the centerpiece 110a in front and from behind by side recesses 103 and in the center, through a support section 101 centrally located in the direction chain drive. In the pre-assembled position, the extreme projections 107 are located in the side recesses 103 and they are supported by their extreme contact surfaces 108 in the central section 101 support. Together with the support of the elements sides 110b, 110c on the support element 120 by means of the joint holes 30, 40 are reached, therefore, a position, in which the pressure on the centerpiece results enough to hold the passage element and it is only necessary exert additional pressure on the centerpiece to interlock the passage element 110 in the support element 120.

By additional pressure on the piece central 110a, the support element 110 composed of several pieces is held in the previously locked position, mentioned above, in the frame of the support element 120 which is formed by the Highlights 121, 122, 123 and in which the retaining pin crosses the hole 60 in the support element 120 with its bars 70 of manipulation and gear behind it. Then the taco expandable 50, fixed in centerpiece 110a through the zone controlled break identified with the number 151, is entered in the housing formed by the handling bars 70 for definitely fix the position of the passage element 110 in the support element 120.

Naturally other variants are possible different from those already mentioned, without abandoning the fundamental idea of the invention within the framework of the claims.

It would be possible, for example, to provide the chain of traction, instead of chain links in the form of embodiment with a passage element 110 and several individual pieces 110a, 110b, 110c, with chain links that present in each case a step element in the form of a single piece with several individual sections linked together, for example, by movie hinges. This can facilitate the assembly of the element step, can be installed in one piece in the support element, without need for greater measuring accuracy of element 120 of support, as in the case of the support element 20 for the 20 element not divided.

Instead of one or more synchronized slots of control channel, in which or in which a bolt attached with the mobile guide side rail in the normal direction of the roller shutter cloth, it would also be possible to provide a fixed bolt and control channel slots with the development that predefines the rotating movement of the slats. Instead of the slot or the control channel slots could also be provided a lane or control lanes arranged in correspondence with the development of the control channel slot, on which or which are or are guided slides joined with the side guide rail moving in the normal direction of the roller shutter cloth.

In the context of the invention it is understood as "control channel channels" any type of cams or tracks adequate control, through which the displacement of the lateral guide rail and therefore finally the rotation of the slats by means of the rotation levers.
