Description

The The invention relates to a building opening shading device according to the preamble of claim 1.

A such building opening shading device, In particular, a roller shutter has a rotatably mounted winding shaft for mounting and deflating a hanging attached to the winding shaft blind in front of the building opening on, which is the main function represents the building opening shading device. Further, the building opening shading device a powertrain for performing an additional function the building opening shading device, For example, in a roller shutter with ausstellbaren guide rails a drive train for issuing the pivot portion of the guide rails or a building opening shading device with louvres that can be sunk, a drive train for up or down louvers the slats.

A generic roller shutter with additional function is for example with the DE 39 00 745 A1 refer to. There, a roller shutter is shown, which has ausstellbare guide rails. The guide rails are accommodated with their upper end in a helical guide of a cam, which can be coupled via a coupling with the drive of the winding shaft. In this case, on the one hand the roller shutter armor can be on the one hand on the drive of the winding shaft and lowered and on the other hand, the Ausstellmechanismus (additional function) can be operated. The cam is connected via a gear to an inner shaft, which is connected via the coupling with the winding shaft. The clutch in this case has a number between the inner shaft and the inner shaft arranged sleeves, which have on their front sides on the one hand driver projections and on the other hand recesses for the Mitnehmervorsprünge. The recesses are wider in the circumferential direction than the projections, so that the winding shaft can initially rotate freely without taking the drive shaft for the Ausstellermechanismus and only when the projections on the shoulders of the recesses attack the drive shaft of the exhibitor is actuated.

there must the number of coupling sleeves or the width of the Recesses and projections in the circumferential direction exactly the curtain length be tuned to a complete Allow draining the curtain without the exhibitor mechanism is set in motion. That means every single shutter depending on the building opening to be covered individually must be configured.

Of these, Starting task of the present invention, a generic Building opening shading device in such a way that a connection of an anti-driveline for an additional function the building opening shading device structurally simple way with high reliability of the building opening shading device is possible.

These The object is achieved with the features of claim 1.

According to the invention for this purpose a detection device is provided which detects whether the Winding shaft at a predetermined peripheral portion or at one given place is covered by a layer of hangings, as well an additional function actuator, which in In response to the output of the detection device the drive train operated or released to operate, if detected is that the winding shaft at a predetermined location or at the specified Peripheral section is not covered by the position of the curtain.

Thereby, that as a trigger for the additional function of concern the hanging on the winding shaft or a position of the curtain on one can be used independently of the Behanglänge and thus without the shading device Individually configured for each building opening must be, in a simple way, the desired additional function triggered, executed or released.

This is particularly advantageous if the location of the curtain, from which detects whether they are the winding shaft at the specified location covered, rests in the wound state directly on the winding shaft, if it is, for example, the top shutter bar of a Roller shutter arm acts, with the curtain is attached to the winding shaft. Because the fact that the drive train is only pressed or is released for actuation when it is detected that the winding shaft at a predetermined location or at the predetermined peripheral portion not covered by the location of the curtain, it is ensured that the Additional function can only be performed when the Behang is completely settled. A default risk due to at the same time as hanging or lowering Actuation of the additional function can thus effectively and be easily avoided.

This can be important, for example, in a curtain with on and zujalousierbaren single slats, in which the additional function, the blinds of the individual slats of the blind, should be performed only in fully extended condition of the blind. Another example of a building opening ver shading device, the additional function should be performed only when fully extended drapery, would be a building opening shading device with extendable guide rails (additional function), in which the expansible pivot portion comprises only a lower leg of the guide rail and the curtain must not be raised or lowered when the pivoting section is issued because a blocking is to be feared at the occurring on the pivot axis kink in the guide groove of the guide rail.

The Additional function actuator can be a own motor drive for the driveline of the Include additional function, as well as a means for operating or enabling the drive in response to the output of the detector and thus ultimately on whether the winding shaft at a given Peripheral section or at a pre-given point of a situation the curtain is covered.

Advantageous However, the drive train has a drive coupling for torque transmitting Coupling to the winding shaft on. The drive coupling can do this a coaxial with the winding shaft rotatably driven rotary drive element and a coupling element via which the rotary drive element can be coupled with the winding shaft. It thus succeeds an operation of main and auxiliary function of the building opening shading device a single drive, namely the drive of the winding shaft. This results in a particularly simple construction of the building opening shading device, both in a hand-operated, but especially in a motor-driven winding shaft. Because the engine control must only drive a motor. If the auxiliary function actuator while the powertrain of the additional function sets in motion, so for example realized as a forced coupling explained below, it suffices for the operation of the building opening shading device In principle, the engine control system is at a complete end position drawn up drapery and an end position when fully drained Curtain and performed additional function pretend.

The Coupling element may be in response to the output of the detection device switchable by the additional function actuator Coupling, which is thus in response to the output of the detection device engaged and uncoupled, ultimately in response to whether the winding shaft at a predetermined peripheral portion or at a predetermined location is covered by a layer of Behangs.

Prefers in the sense of a simple structure, however, a forced coupling, in which the coupling element is constructed so that the drive train the auxiliary function and the winding shaft of the building opening shading device over the Coupling element are forcibly decoupled when the winding shaft covered at the given location by the position of the blind, and otherwise forced to transmit torque. The indication that the drive train of the additional function and the winding shaft "forcibly are decoupled when the winding shaft at the specified location covered by the location of the blind, and otherwise forcibly torque-transmitting coupled "includes in the sense Of course, the invention also in reality always necessary for switching from the decoupled to the coupled state Switching time between the two states. This forced coupling, in which the coupling element, the detection device and the additional function actuator thus embraces or embodies or instead of the detection device and the auxiliary function actuator could be for yourself or along with the features the further claims to the subject of a separate Registration will be made.

there can the coupling element one at the specified location between an adjacent and a protruding positions movable Having the winding shaft recorded movement portion, which is biased against the position of the curtain, so that the movement section is held in the adjacent position when the location of the blind covered the predetermined point of the winding shaft, and the protruding Position occupies when the predetermined position of the winding shaft is not from the location of the curtain is covered. The movement section can be a Have driver and the rotary drive element at the radial height of the driver located in the protruding position an attack for the driver, so that the driver in the projecting Can attack position on the stop of the rotary drive element and not in the adjacent position.

However, it would also be conceivable to have a coupling in which the movement section is fastened to the rotary drive element instead of to the winding shaft. In this case, the movement section could have a radially biased inwardly driver, which extends in the axial direction to the winding shaft and grinds at unwound hang on the outer layer of the curtain. At the given, to be scanned peripheral portion of the winding shaft, the winding shaft then have a stop for the driver, which is covered by not fully unwound Behang of the curtain. When the last layer of the curtain is unwound at the predetermined peripheral portion engages the driver to the stop, for example, in a trough on the winding shaft circumference.

Of the Movement section but could neither on the rotary drive element still be attached to the winding shaft, but z. B. on a koxial taken up between the rotary drive element and the winding shaft Disc, which for example have a folding wing can, on the one hand locked with the winding shaft, as soon as the last Location of the curtain of a corresponding latching section on the given Position of the winding shaft is unwound, on the other hand with the rotary drive element.

The Rotary drive element can be a torque transmitting with the winding shaft coupled, coaxial with a rotational axis of the winding shaft on a side part of a roller shutter box rotatably mounted disc include. The driver on the moving portion of the winding shaft can then attack when engaging the disc, z. B. at one of an inner circumference of the Scheib inwardly projecting drive cam.

If the rotary drive element coaxially at least in an arc section to a rotation axis of the winding shaft guided print chain includes and the print chain is connected to a disc can the driver to attack the disc or directly to pressure chain. For direct attack on the pressure chain, the driver facing the guide the pressure chain in the peripheral region in which the driver in the radial direction wanders open, and at the end of the pressure chain a suitably shaped Stop be provided for the driver.

Advantageous the curtain is attached to the winding shaft so that after the complete draining of the curtain another rotation the winding shaft in Ablassrichtung to a for engaging and pressing the drive train of the additional function required angle possible is.

Around for example, in a blind with one hanging from each other Roller shutter slats existing shuttering armor for engaging and Actuating the drive train of the additional function required "freewheel" the To provide winding shaft, so a further rotation in Behangablassrichtung to allow, when the roller shutter completely deflated and is seated with its end bar down, the Roller shutter armor, for example, after the sitting up draftless expectant traction cables are attached to the winding shaft. This is in but too wobbly in many cases. The hangings could further via a winding shaft side hinged Behangabschwenkflügel be attached to the winding shaft, which pivots off when the Behang rests on its lower end, so that the winding shaft at fully drained curtain can continue to turn in unwinding. With these measures, the winding shaft can be however, continue to turn only by a relatively small angle segment after the hanging up, so that the additional function within a very small winding shaft rotation angle triggered and carried out must become.

Especially Advantageously, therefore, a hanging fastening device is provided, which a fixedly mounted on the circumference of the winding shaft stop section and behangseitig connected to the curtain Behangaufnahmeabschnitt. The Behangaufnahmeabschnitt is rotatable on the winding shaft taken, the stopper portion has a radial direction the winding shaft projecting stop on and the Behangaufnahmeabschnitt at the axial height of the stopper a driver. attack and drivers are designed so that the driver in in the lift direction of the blind rotating winding shaft the stop can stop and in the discharge direction of the blind rotating winding shaft can release the stop.

At the Draining the curtain reaches this one fully extended position, in the hangings with his end bar, for example, on one Window sill rests and thus further rotation of the winding shaft in a conventional mounted on the winding shaft roller shutter would prevent. If the curtain is over the proposed hanging fastening device connected to the winding shaft, solves the winding shaft side stop of the behangseitigen Driver, if the winding shaft continues in Behangablassrichtung is actuated, allowing further rotation of the winding shaft and thus engagement and actuation of the drive train the additional function is possible.

For the further rotation is an angular segment of almost 360 ° Available. If more is needed, then the hanging fastening device be constructed in several stages. So the stop for the driver on a rotatably received on the winding shaft Ring member may be formed, which in turn another Driver for another, stationary on the circumference of the winding shaft attached, projecting in the radial direction of the winding shaft stop has, wherein the further driver over the other Stop on the side in the direction of lift of the curtain Winding shaft is provided so that then nearly 720 ° rotation angle would be available.

The stopper portion may comprise two sleeves spaced around the winding shaft in the axial direction of the winding shaft, and the hanging receiving portion one between the Man cradles rotatably arranged Behangaufnahmschlitten. The Behangaufnahmitten can be advantageously taken with runners sections in guides in the sleeves movable, which extend in winding shaft circumferential direction.

First, reference is made to the 1 , In it is a total with 1 designated roller shutter, which one in a roller shutter box 7 with side parts 8th recorded winding shaft 2 ( 3 ), on which a roller shutter 3 ( 14 ) is recorded on and unwound. To guide the roller shutter 3 points the shutter 1 Side guide rails 4a . 4b on, which two via a lower cross member to a pivoting portion 4 connected, swing-leg have. The guide rails are on their non-swinging legs each with a from the shutter box 7 to the lower edge of the swing-out leg of the respective guide rail 4a . 4b extending frame member 11 connected, for example, put together. In the context of the invention, the non-swinging legs of the guide rails could also be formed integrally with the frame member. The swinging guide legs are on the stationary, upper sections of the guide rails 4a . 4b each articulated via an insertable into the profiles of the guide rail halves swivel joint. Such an exhibitor joint is the subject of its own utility model DE 20 2008 013 422 , which should be included here.

In the non-pivoted state of the pivoting portion thus results in a smooth outer surface of the guide rails, because also for exhibiting the pivot portion behind the exhibitable guide legs of the guide rails 4a . 4b , arranged exhibitor arm or the arranged there exhibitor arm assembly is received in a pivot portion facing the outlet opening or arm receiving in the frame member, so that the swing-leg of the guide rails 4a . 4b , in the uninhibited state congruent on the two frame components or frame profiles 11 to come to rest.

How the particular 2 can be seen, is the with 12 designated exhibitor arm while at its upper end in the frame member 11 taken and engages with its lower end on the swing-leg of the respective guide rail 4a . 4b , So a total of the pivoting section 4 the exhibitor store 1 at. In a middle area of the exhibitor arm 12 is doing a joint 13a a scissor arm 13 articulated with its upper end, which with its lower end as well as the exhibitor 12 with its upper end through the with 11a designated passage opening in the frame member 11 protrudes and is recorded there. The scissor arm 13 is at his in the frame component 11 recorded attachment section 16 hinged, which in the frame component 11 slidably received, as in particular in conjunction with the 2 . 7 , and 8th can be seen. The exhibitor arm 12 is on the other hand also in a frame component 11 located attachment section 14 (Comp. 3 ), which is fixed in the frame member characterized in that above the serving as a mounting portion carrier 14 for a joint 14a of the exhibitor arm 12 a stop in the frame member 11 is provided against which the exhibitor arm - attachment section 14 - During the pivoting of the pivoting section 4 over the scissor arm 13 is pressed, as will be explained below.

The frame component 11 has therefore behind the passage opening 11a for the exhibitor arm 12 and the scissor arm 13 a preferably designed as a sliding guide receptacle for the attachment sections 14 . 16 on. This receptacle is connected to the roller shutter box via a passage opening extending up to the upper end side of the frame component, or can be connected, through which pressure or traction means to be described below can be passed, via which a force necessary for issuing the exhibitor arm can be transmitted.

The above-described, from the frame member 11 and the non-swinging portion of the guide rail 4a respectively. 4b existing profile unit can be made the subject of a separate application, with the other features mentioned above, in particular the recorded in the guide rail profile pivot and thus hinged to the frame member guide rail unit pivot leg of the guide rail, as well as from the upper end of the Frame member extending to the receiving opening for the issuer arm assembly passageway for the tension or pressure means, as well as the design of the receiving opening as a sliding guide can be included.

Like from the 2 . 7 and 8th shows, is in the receiving guide in the profile component 11 below the attachment section 16 of the scissor arm 13 over which it is slidingly slidable in the Gleitführungsaufnahme, a bolt block 18 or a locking unit 18 or a latch stopper section 18 , which one with 19 designated locking hook carries, with which the pivot portion 4 im to the frame component 11 attached state can be locked. For this purpose, the pivoting section 4 at a the latch hook 19 corresponding portion of the swinging leg of the guide rails 4a . 4b in each case an undercut latch receiving opening, which the latch hook 19 in the locked, lower position ( 7 ) engages behind.

The bolt stopper section 18 is also as a sliding in the Gleitführungsaufnahme in the frame member 11 recorded block formed, which has a stop edge on the upper side 21 has, with which he against a lower-side stop edge of the slidably formed scissor arm attachment portion 16 runs when, as a pull rope 10 trained traction means in the locked position of the latch hook 19 is pulled and the latch portion 18 is thereby raised to the unlocked position ( 8th ). On further pull on the pull rope 10 pushes the bolt stop section 18 with his stop 21 against the underside stop of the scissor arm attachment section 16 and thereby raises it.

A powertrain with which the exhibitor arm 12 against the pivoting section 4 is issued, is a total of 3 to remove, wherein the locking unit 18 and the locking of the pivoting portion to the frame members 11 are provided only as optional training. Conversely, however, could also represent the lock itself, the additional function which is performed on the drive train when the deployment mechanism is operated by other drive means.

Of the 3 it can be seen that the pull rope 10 via a pulley 20 at the latch stop section 18 is guided and with its end on Befestigungsigunsabschnitt 16 of the scissor arm 13 at is bound. However, the traction cable could also be connected directly to the bolt stop section, in which case no deflection roller would be necessary. Would pulled on the attached to the bolt stop portion pull rope, this would run after overcoming the necessary for unlocking path against the scissor arm attachment portion and push it as well as in the illustrated embodiment of the invention, wherein bolt stop portion and scissor arm mounting portion in the Gleitführungsaufnahme in the frame member are guided.

The one from the scissor arm 13 and the articulated arm hinged thereto 12 existing Ausstellungsarmmechanismus relies on the exhibitor arm attachment section 14 on the upper side against a corresponding stop in the frame component 11 which is not explicitly shown in the figures. A train on the pull rope 10 So leads after the start of the bolt stopper section 18 against the scissor arm attachment section 16 to a spreading out of the scissor arm 13 and the exhibitor arm 12 formed scissors, the exhibitor 12 about his as a rotatable recorded rubber roller 15 trained attack section on the underside of the pivot legs of the guide rails 4a . 4b and thus on the pivoting section 4 of the shutter 1 attacks.

The rope 10 is at the other end on a perimeter with a 5 designated, on the side panel 8th ( 1 ) of the roller shutter box 7 rotatably mounted pulley attached and can be wound up and unwound via a rotation of the pulley. As a drive for the pulley 5 is there with the 2 designated winding shaft of the shutter 1 intended. The pulley 5 is here as from the winding shaft 2 permeated hollow disc formed and thus forms a coaxial with the winding shaft 2 arranged rotary drive element and is connected via a coupling element 9 ( 9 - 11 ) transmitting torque with the winding shaft 2 detachable and decoupled from this.

The coupling element 9 will, as will be explained in detail later, from a decoupled position in which it is when the winding shaft 2 at a given location 25 or at a predefined peripheral portion of a layer 30 of the blind 3 is covered, moved into a dome position when the location 30 of the blind 3 the given place 25 the winding shaft 2 no longer covered ( 12 . 13 ). About the coupling element 9 Thus, it is finally detected whether the winding shaft 2 at the given location 25 from one location 30 of the blind 3 is covered and the additional function of the shutter (here the Ausstellermechanismus) operated in response to whether it is detected that the winding shaft is covered at the predetermined location of the position of the curtain or not. The coupling element 9 thus forms a detection device and an additional function actuator for actuating the drive train of the additional function, wherein the drive train according to the in 3 shown embodiment of the coupling element 9 over the pulley 5 and the cable 10 to the bolt stopper section 18 and from there on the scissor arm attachment section 16 and the scissor arm 13 and the issuer arm attachment portion 14 to the exhibitor arm 12 leads.

An alternative embodiment of the drive train of the additional function of the shutter, here the pivoting of the exhibitor 12 (and the optional lock) is the 4 refer to. In this case, instead of a traction means, a pressure (and tensile) transmitting push rod 110 provided, which with its lower end on the movably received in the Gleitführungsaufnahme in the corresponding frame member mounting portion 114 is attached, where the exhibitor arm 12 via an exhibitor joint 114a is articulated. The push rod 110 is at its upper end with a pressure chain 105 connected, which via inlet guides 117c into the interior of the roller shutter box 7 is guided, which instead of the side panels 8th side panels 108 having, in addition to Umlenkführungsrippen 117b in which the pressure chain on a rotatable on the side part 108 recorded disc 105a is deflected, a circular arc concentric around the disc 105a circumferential guide rib 117a having. Between the circular guide rib 117a and the sprocket 105a is just as much space that the pressure chain 105a fits into it. A pressure chain according to the invention is a chain which can transmit a compressive force. The pressure chain 105 is in a manner not shown on the sprocket 105a attached. Also not shown is a on the inner circumference of the support of the pressure chain 105 projecting driving cam on the disc 105a ,

Will the disc 105a in printing direction of the pressure chain 105 pressed, so is the pressure chain 105 a pressure force on the push rod 110 and from there to the attachment section 114 transfer. On the attachment section 114 of the exhibitor arm 12 opposite bottom of the exhibitor arm 12 and that about the joint 13a hinged scissor arm 13 formed scissor mechanism is the scissor arm 13 on his scissor arm attachment section 116 articulated, which is supported up to a necessary to actuate the lock, small way substantially stationary ( 5 . 6 ), so that the Ausstellermechanismus spreads and the pivoting section 4 is pivoted from the frame member.

The details of the locking unit used here 118 . 119a . 119 . 120 are doing the 5 and 6 refer to.

5 shows an unlocked position of the locking unit 118 . 119a . 119 . 120 swung exhibitor, as well as the 4 can be seen. 6 On the other hand, it shows a locked position of the locking mechanism when the pivoting section or exhibitor is seated. The locking unit 118 . 119a . 119 . 120 has a bolt block 118 on, in which the latch hook 119 about a joint 120 is received articulated. On the latch hook 119 opposite side of the joint 120 there is a rocker arm section 119a of the latch hook 119 , Will, as in 4 represented by the push rod 110 a pressure on the scissors mechanism 12 . 13 exercised, this pressure is over the scissor arm 13 on the scissor arm attachment section 116 transferred to the scissor arm 13 about a joint 116a is articulated. The scissor arm attachment section 116 is in the bolt block 118 or the bolt stopper portion 118 slidably guided and then presses on the rocker arm section 119a of the latch hook 119 , The bolt stopper section 118 is supported on the underside of a corresponding stop in the frame member, so that when pressure is applied via the push rod 110 Although first to unlock the latch hook 119 necessary way from the attachment section 116 of the scissor arm 113 is returned, but this after a short time to a stop 121 on the latch section 118 strikes and over there by the push rod 110 exerted pressure, which over the stop of the frame member on which the latch stop portion 118 is seated, is countered.

In the 9 - 13 is the drive coupling 5 . 9 of in 3 illustrated drive train with traction cable explained in more detail.

It is a positive clutch, which is constructed so that the drive train of the additional function, ie the drive train of Ausstellermechanismus and the optional lock and the winding shaft 2 of the shutter 1 about that with 9 designated coupling element are forcibly decoupled when the winding shaft 2 at a given location not from a last armored staff 30 a roller shutter 3 is covered (ie by a position of the blind) and forcibly engaged when the last armored staff 30 from the winding shaft 2 takes off. By thus grasping that last lamella 30 from the winding shaft 2 stands out, it is actually recorded that the blind 3 completely from the winding shaft 2 is done, ie that an additional function of the shutter can be performed, which would lead to complications if it were carried out as long as the unwinding or winding of the curtain 3 is still going on. At the in 1 in total view to be taken blinds 1 If this were the case, since the hanging on the pivot joints of the pivoting section 4 a kink in the guide groove of the guide rails 4a . 4b would have to follow if he swings while the exhibitor 4 would be in operation.

In the present embodiment, the coupling element 9 a total of 22 designated folding wing on which a joint 27 on a joint carrier 28 is attached, in turn, on one over the winding shaft 2 laid cuff 29 is pushed and thus the coupling element 9 stationary on the winding shaft 2 sets. The folding wing 9 has an investment process 25 on, at the point of which is detected, whether they are on the location 30 of the blind 3 is covered, at the winding shaft 2 abuts when the last lamella 30 against the plant extension 25 and thus against the winding shaft 2 suppressed. Will the last lamella, or the last roller shutter armor bar 30 from the winding shaft 2 settled ( 13 ), so the investment process becomes 25 via a torsion spring, not shown in the joint 27 along with the entire folding wing 22 to the outside of the winding shaft 2 splayed. It is on the folding wing 22 in the axial direction of the winding shaft 2 projecting driving pin 26 attached, which, like 9 shows, in to the winding shaft 2 adjacent position of the folding wing 22 on an inner track with the winding shaft 2 co-rotated and in folded from the winding shaft position of the folding wing 22 on an outer track with the winding shaft 2 co-rotated, like that 10 and 11 can be seen.

The driving pin 36 extends in the axial direction of the winding shaft into a region below an inner circumferential shoulder on a cylindrical portion 24a the pulley 5 , wherein on the inner periphery of the cylindrical portion 24a an inwardly projecting driver cam 24 is provided.

Is the curtain 3 So in a not completely unwound from the winding shaft state or pushes the last shutter bar 30 not against the investment process 25 of the folding wing 22 , is the driving pin 26 on the in 9 illustrated inner orbit. Once the folding wing 22 folds down, because the last shutter bar 30 from the winding shaft 2 is handled, gets the takeaway 26 to the outer orbit ( 10 ) and hits against the driver socks 24 ( 11 ) and takes on a further movement of the winding shaft 2 in winding shaft outlet direction the pulley 5 with, causing the cable pull 10 on the pulley 5 is wound up and the in 3 displayed exhibitor terms is set in motion.

In particular, in a roller shutter shell consisting of armored tanks such as the roller shutter 3 must the curtain 3 so at the winding shaft 2 be fixed that after complete draining of the curtain further rotation of the winding shaft in the discharge direction is possible, at least by such an angle that it is sufficient for engaging and operating the drive train of the additional function.

In this regard is on the 14 and 15 referenced in which a hanging fixture 6 is shown with the hangings 30 on the winding shaft 2 is attached. The hanging fixture 6 has winding shaft side two spaced from each other on the winding shaft deferred sleeves 36 on, on each of which a stop projection 34 in the radial direction of the winding shaft 2 projects. Between the two cuffs 35 and the attacks 34 is a Behangaufnahmschlitten 31 rotatably received, which with runners sections in circumferential grooves of the sleeves 34 opposite the winding shaft 2 is recorded rotatably. At the curtain pickup sled 31 are in the axial direction of the winding shaft 2 projecting carriers or counterstops 35 formed, which, as in 14 shown on the winding shaft 2 wrapped curtain 3 or not yet fully developed curtain 3 in abutment with the projections 34 stand and, if the hangings 3 completely unwound, out of engagement with the above attacks 34 reach, which are rotated in a further rotational movement of the winding shaft in Behangablassrichtung of the attacks.
