Description

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

A generic building-opening shading device, in particular a roller shutter has a rotatably mounted winding shaft for mounting and discharging a fixed to the winding drum curtain in front of the building opening, wherein the curtain is connected via at least one curtain mounting device with the winding shaft.

For certain purposes, it may be advantageous if the winding shaft can be rotated with draped curtain, without the shading device must be dismantled.

To allow, for example, in a roller shutter with an existing hanging slats shutter roller further rotation of the winding shaft in Behangablassrichtung when the shuttering armor is completely drained and seated with its bottom end rail, the roller shutter armor could be attached to the winding shaft, for example via zugens becoming undignified after sitting on the winding shaft be. However, this is too shaky in many cases.

Such a shutter is for example from the European patent EP 0 965 723 B1 known. Here is a curtain with a top slat over elastic connecting strip connected to a winding shaft. Further, there is provided on articulated interconnected links on the winding shaft rod whose two axial ends are in turn associated with the elastic strip driver.

As an alternative to the connection via traction ropes or elastic connecting strips, the curtain can furthermore be fastened to the winding shaft via a winding pivot side hinged swinging side, which pivots when the curtain rests at its lower end, so that the winding shaft can continue to rotate in the unwinding when drape fully drained.

Such a solution is in the European patent specification EP 1 111 185 B1 (E2), which shows a shutter with a safety device against pushing up. The shutter has leaf springs, over which the shutter curtain is attached to the winding shaft. If the winding shaft is actuated in the winding direction, the elastic leaf springs can be wound onto the winding shaft and thus the curtain. About the winding shaft, a rotatable sleeve is further pushed, which is arranged rotatable about a certain angular range on the winding shaft. The sleeve has a driver, which is associated with a stationary mounted on the winding shaft stop section. The sleeve serves as a hold-down for the leaf springs. The rotatable arrangement of the sleeve on the driver and the stopper portion, however, serves to compensate for changes in length of the roller shutter, for example due to temperature fluctuations, in the different seasons.

With these measures, however, the winding shaft can only continue to turn by a relatively small angle segment after the curtain is seated.

Another solution is in the patent DE 3 900 745 A1 disclosed with all features of the preamble of claim 1, which shows a displayable shutters.

On this basis, it is therefore an object of the present invention to provide an improved in the above sense building opening shading device.

This object is achieved with the features of claim 1.

According to a Behangbefestigungsvorrichtung is provided, which has a fixedly mounted on the circumference of the winding shaft stop portion and behangseitig connected to the curtain Behangaufnahmeabschnitt. Here, the Behangaufnahmeabschnitt is rotatably received on the winding shaft, the stopper portion has a projecting in the radial direction of the winding shaft stop and the Behangaufnahmeabschnitt on the axial height of the stopper a driver. Stop and dog are designed so that the driver can stop the stop when rotating in the lift direction of the blind winding shaft and can release the stop in the direction of discharge of the blind rotating winding shaft.

When draining the curtain this reaches a fully extended position in which a conventionally attached to the winding shaft curtain, for example, roller shutter would prevent further rotation of the winding shaft. However, if the curtain is connected to the winding shaft via the curtain fastening device according to the invention, then the winding shaft-side stopper is released from the other side carrier if the winding shaft is still actuated in the hanging direction, so that a further rotation of the winding shaft is possible.

For the further rotation, an angle segment of almost 360 ° is available. If more is needed, then the hanging fastening device can also be constructed in several stages. Thus, the stop for the driver on a rotatably received on the winding shaft ring member may be formed, which in turn has another driver for another, fixedly mounted on the circumference of the winding shaft, projecting in the radial direction of the winding shaft stop, wherein the further driver relative to the other stop on the side of the curtain in the direction of the lift Winding shaft is provided, so that then almost 720 ° rotation angle would be available.

Thus, according to the invention, the hanging fastening device is designed in such a way that, after complete draining of the curtain, a further rotation of the winding shaft in the direction of discharge by a desired angle is possible. The winding shaft-side stop and the behangseitige driver are arranged so that they get in rotation in the winding direction in the attacking each other and get out of attack on rotation of the winding shaft in the discharge direction.

Thus, the winding shaft can be rotated, for example, for inspection purposes with fully drained curtain. However, this is particularly advantageous if the building opening shading device has an additional function, such as the operation of a Ausstellermechanismus in the case of a shutter with ausstellbaren guide rails, the operation of a closing mechanism or the blinds of louverable slats of Rolladenbehangs. Because then the drive train for the additional function of the shading device can be coupled in a simple manner to the drive of the winding shaft, which can be used for the operation of the additional function after draining the curtain by the present invention designed Behangbefestigungsvorrichtung available winding shaft rotation angle segment.

In this way, a particularly simple construction of a building opening-shading device with additional function, both in a hand-operated, but especially in a motor-driven winding shaft results. Because the engine control has only one motor to control. If in this case the drive train of the additional function is set in motion after the curtain has been drained via the winding shaft, for example via the forced coupling explained below, it is sufficient in principle for the operation of the building opening shading device to provide the motor control with an end position fully draped curtain and an end position with completely draped curtain and performed additional function pretend.

If the building-opening shading device is equipped with additional function, it preferably has a forced coupling of winding shaft and drive train of Zusatzfuntion in which a coupling element is constructed so that the drive train of the additional function and the winding shaft of the building opening shading device are forcibly decoupled via the coupling element, when the winding shaft is covered at the predetermined location by the position of the curtain, and otherwise forcibly coupled to transmit torque. The statement that the drive train of the additional function and the winding shaft "are forcibly decoupled when the winding shaft is covered at the predetermined location of the position of the curtain, and otherwise forcibly torque-coupled coupled" for the purposes of the invention, of course, always in reality Switching from the decoupled in the coupled state necessary switching time between the two states.

In this case, the coupling element has a recorded at the predetermined location between an adjacent and a protruding positions movably on the winding shaft movement portion which is biased against the position of the curtain, so that the moving portion is held in the adjacent position when the position of the curtain covered predetermined position of the winding shaft, and the protruding position occupies when the predetermined position of the winding shaft is not covered by the position of the curtain. The movement portion may comprise a driver and the rotary drive element to radial. Height of the located in the protruding position driver a stop for the driver, so that the driver can engage in the protruding position on the stop of the rotary drive element and not in the adjacent position.

Advantageous developments are the subject of the remaining dependent claims.

Thus, the stopper section may comprise two sleeves arranged around the winding shaft in the axial direction of the winding shaft, and the hanging receiving section may comprise a hanging receiving carriage which is rotatably arranged between the sleeves.

The Behangaufnahmitten can be advantageously taken with runners sections in guides in the sleeves movable, which extend in winding shaft circumferential direction.

In particular, if the curtain is formed as consisting of individual bars roller shutter, the Behangaufnahmeabschnitt may further comprise a winding shaft side hinged Behangabschwenkflügel on which the curtain is attached, so as to increase the zurücklegbaren by the winding shaft without entrainment of the path. If the curtain is at its lower end, and the winding shaft rotates further in the unwinding direction, first the Behangabschwenkflügel and thus the upper Behangende of the winding shaft turns off before the winding shaft side driver releases the behangseitigen stop.

First, reference is made to the FIG. 1 , It shows a roller shutter designated as a whole with 1, which has a winding shaft 2 received in a shutter box 7 with side parts 8 (FIG. FIG. 3 ), on which a roller shutter 3 ( Fig. 14 ) is recorded on and unwound. To guide the roller shutter shell 3, the roller shutter 1 side guide rails 4a, 4b, which have two connected via a lower cross member to a pivot portion 4, swing-leg. The guide rails are connected at their non-swinging legs in each case with one of the shutter box 7 to the lower edge of the swinging leg of the respective guide rail 4a, 4b extending frame member 11, 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 hinged to the stationary, upper sections of the guide rails 4a, 4b each via an insertable into the profiles of the guide rail halves pivot joint. Such an exhibitor joint is the subject of its own utility model DE 20 2008 013 422 ,

In the non-pivoted-down state of the pivoting section, there is thus a smooth outer surface of the guide rails, because also the exhibitor arm or the exhibitor arm arrangement arranged there for exhibiting the pivoting section behind the deflectable guide legs of the guide rails 4a, 4b is located in an outlet opening or arm receptacle facing the pivoting section Frame member is included, so that the swiveling leg of the guide rails 4a, 4b, congruent in the non-flared condition on the two frame members or frame profiles 11 come to rest.

How the particular FIG. 2 it can be seen, the exhibitor arm denoted by 12 is received at its upper end in the frame member 11 and engages with its lower end to the swing-leg of the respective guide rail 4a, 4b, so a total of the pivot portion 4 of the exhibitor roller shutter 1. In a central region of the exhibitor arm 12, a scissor arm 13 is articulated with its upper end on a joint 13a, which protrudes with its lower end as well as the issuing arm 12 with its upper end through the opening 11a designated in the frame member 11 and received there is. The scissors arm 13 is articulated at its recorded in the frame member 11 mounting portion 16, which is slidably received in the frame member 11, in particular in conjunction with the Figures 2 . 7, and 8 can be seen. By contrast, the issuer arm 12 is connected to a fastening section 14, which is likewise located in the frame component 11 (see FIG. FIG. 3 ), which is fixed in the frame member characterized in that above the serving as a mounting portion support 14 for a joint 14 a of the 12 exhibitor arm 12 a stop in the frame member 11 is provided against the exhibitor arm - mounting portion 14 - during pivoting of the pivoting section. 4 is pressed over the scissor arm 13, as will be explained below.

The frame member 11 thus has behind the passage opening 11 a for the exhibitor arm 12 and the scissor arm 13 preferably designed as a sliding guide receptacle for the mounting portions 14, 16. 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 by means of which pressure or pressure elements to be described below Traction means can be performed over which a necessary to issue the exhibitor arm force can be transmitted.

The above-described, consisting of the frame member 11 and the non-swiveling portion of the guide rail 4a and 4b profile unit can be made for the subject of a separate application, with the other features mentioned above, in particular the recorded in the guide rail profile swivel joint and the thus hinged to the frame member guide rail unit pivot leg of the guide rail, as well as extending from the upper end of the frame member 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 sliding can be involved.

Like from the Figures 2 . 7 and 8 It is apparent in the receiving guide in the profile member 11 below the mounting portion 16 of the scissor arm 13, via which it is slidably displaceable in the Gleitführungsaufnahme, a locking block 18 and a locking unit 18 or a bolt stopper portion 18 which carries a designated 19 latch hooks, with which the pivot portion 4 can be locked in the voltage applied to the frame member 11 state. For this purpose, the pivoting portion 4 at a corresponding to the latch hook portion 19 of the swiveling leg of the guide rails 4a, 4b each have an undercut latch receiving opening, which the latch hooks 19 in the locked, lower position ( FIG. 7 ) engages behind.

The bolt stopper portion 18 is also formed as a slidably received in the Gleitführungsaufnahme in the frame member 11 block which has a stop edge 21 on the upper side, with which it runs against a lower-side stop edge of the slidably configured scissor arm mounting portion 16, when formed on the traction cable 10 Pulling means is pulled in the locked position of the latch hook 19 and the latch portion 18 is thereby raised to the unlocked position ( FIG. 8 ). Upon further train on the pull cable 10 of the Riegelanschlagsabsachnitt 18 presses with its stop 21 against the lower-side stop of the scissor arm mounting portion 16 and raises this by.

A drive train, with the exhibitor arm 12 is issued against the pivot section 4, is a total of FIG. 3 can be seen, wherein the locking unit 18 and the locking of the pivoting portion are provided on the frame members 11 only as an optional development. 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 FIG. 3 it can be seen that the pull cable 10 is guided over a guide roller 20 on the bolt stop portion 18 and is connected at its end on Befestigunsabschnitt 16 of the scissors arm 13. 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 existing from the scissor arm 13 and the articulated thereto 12 exhibitor arm based on the exhibitor arm mounting portion 14 on the upper side against a corresponding stop in the frame member 11 from which is not explicitly shown in the figures. A train on the pull cable 10 thus leads after the start of the bolt stop portion 18 against the scissor arm attachment portion 16 for spreading out the scissors formed by the scissor arm 13 and the arm 12, the exhibitor arm 12 formed on its rotatably received rubber roller 15 attack portion below the pivot legs of the guide rails 4a, 4b and thus on the pivot portion 4 of the shutter 1 attacks.

The traction cable 10 is at its other end on a circumference of a designated 5, on the side part 8 ( FIG. 1 ) of the roller shutter box 7 rotatably mounted sheave and can be wound up and unwound via a rotation of the sheave. As a drive for the pulley 5 while the designated winding shaft 2 of the shutter 1 is provided. The pulley 5 is formed as penetrated by the winding shaft 2 hollow disc and thus forms a coaxial with the winding shaft 2 arranged rotary drive element and is connected via a coupling element 9 (Fig. FIGS. 9-11 ) torque transmitting with the winding shaft 2 detachable and decoupled from this.

The coupling element 9 is thereby, as will be explained in detail later, from a decoupled position in which it is located when the winding shaft 2 is covered at a predetermined location 25 or at a predefined peripheral portion of a layer 30 of the curtain 3 moved in a coupling position when the layer 30 of the curtain 3, the predetermined point 25 of the winding shaft 2 is no longer covered ( Fig. 12, 13 ). About the coupling element 9 is thus finally detected whether the winding shaft 2 is covered at the predetermined location 25 of a layer 30 of the curtain 3 and the additional function of the shutter (here the Ausstellermechanismus) actuated in response to whether it is detected that the winding shaft the predetermined place is covered by the position of the blind or not. The coupling element 9 thus forms a detection device and an additional function actuating device for actuating the drive train of the additional function, wherein the drive train according to the in FIG. 3 shown embodiment of the coupling element 9 via the pulley 5 and the cable 10 for Latch stop portion 18 and from there on the scissor-arm attachment portion 16 and the scissor arm 13 and the exhibitor arm attachment portion 14 to the issuing arm 12 leads.

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

If the disk 105a is actuated in the printing direction of the print chain 105, a pressure force is transmitted to the push rod 110 and from there to the mounting portion 114 via the pressure chain 105. On the opposite side of the mounting portion 114 of the 12 exhibitor arm 12 formed from the exhibitor arm 12 and the joint 13a hinged scissor arm 13 scissor mechanism of the scissor arm 13 is hinged to its scissor arm mounting portion 116, which except for a to Actuating the latch necessary, small way essentially supports stationary ( FIG. 5, FIG. 6 ), so that the Ausstellermechanismus spreads and the pivoting portion 4 is pivoted away from the frame member.

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

FIG. 5 shows an unlocked position of the locking unit 118, 119a, 119, 120 swung exhibitor, as they also FIG. 4 can be seen. FIG. 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 in this case has a locking block 118, in which the locking hook 119 is pivotally received via a hinge 120. On the side opposite the latch hook 119 side of the joint 120 is thereby a Kipphebelabschnitt 119a of the latch hook 119. Will, as in FIG. 4 shown, exerted by the push rod 110, a pressure on the scissor mechanism 12, 13, this pressure is transmitted via the scissor arm 13 on the scissor arm attachment portion 116, on which the scissor arm 13 is articulated via a hinge 116 a. The scissor arm mounting portion 116 is slidably guided in the locking block 118 and the bolt stop portion 118 and then presses on the Kipphebelabschnitt 119 a of the latch hook 119. The latch stop portion 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 initially the necessary to unlock the latch hook 119 path is covered by the mounting portion 116 of the scissor arm 113, but after a short time strikes a stop 121 on the latch portion 118 and is held there over the pressure exerted by the push rod 110, which is countered over the stop of the frame member on which the latch stop portion 118 is seated, is countered.

In the FIGS. 9-13 is the drive coupling 5, 9 of in Fig. 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 locking and the winding shaft 2 of the shutter 1 via the designated coupling element 9 are forcibly decoupled when the winding shaft 2 at a predetermined location is not covered by a last armor bar 30 of a roller shutter 3 (ie, a position of the curtain) and is forcibly engaged when the last armor bar 30 lifts from the winding shaft 2. By thus detecting that the last lamella 30 lifts off from the winding shaft 2, it is actually detected that the curtain 3 is completely unwound from the winding shaft 2, ie that an additional function of the roller shutter can be performed, which would lead to complications if they would be performed as long as the unwinding or winding of the curtain 3 is still in progress. At the in FIG. 1 This would be the case in overall view of the roller shutter 1, since the curtain on the pivot joints of the pivoting section 4 would have to follow a bend in the guide groove of the guide rails 4a, 4b, if it were in operation during pivoting out of the exhibitor 4.

In the present embodiment, the coupling element 9 has a generally designated 22 folding wing, which is fastened via a hinge 27 to a joint carrier 28, which in turn is pushed onto a laid over the winding shaft 2 mounting sleeve 29 and thus the coupling element 9 stationary on the winding shaft 2 determines. The Abklappflügel 9 in this case has a contact extension 25, which is at the point, is detected by whether it is covered by the layer 30 of the blind 3, on the winding shaft 2 when the last blade 30 against the contact extension 25 and thus against the winding shaft 2 presses. If the last lamella, or the last roller shutter armor 30 is unwound from the winding shaft 2 ( FIG. 13 ), so the contact extension 25 is splayed out by a torsion spring, not shown in the joint 27 together with the entire folding wing 22 to the outside of the winding shaft 2. It is on the Folding wings 22 a projecting in the axial direction of the winding shaft 2 driving pin 26 is attached, which, like FIG. 9 shows, in co-rotating with the winding shaft 2 position of the folding wing 22 on an inner path with the winding shaft 2 and rotated in folded-down position of the folding blade 22 of the folding blade 22 on an outer track with the winding shaft 2, as the FIGS. 10 and 11 can be seen.

The driving pin 26 extends in the axial direction of the winding shaft into a region below an inner peripheral shoulder on a cylindrical portion 24a of the sheave 5, wherein on the inner circumference of the cylindrical portion 24a an inwardly projecting driving cam 24 is provided.

If the curtain 3 is thus in a state not completely unwound from the winding shaft or if the last roller shutter bar 30 does not press against the contact extension 25 of the folding leaf 22, the driving pin 26 is located on the in FIG. 9 illustrated inner orbit. As soon as the folding wing 22 folds down, because the last shutter bar 30 is unwound from the winding shaft 2, the driving pin 26 comes to the outer orbit ( Fig. 10 ) and abuts against the drive cam 24 ( Fig. 11 ) and takes in a further movement of the winding shaft 2 in Wickelwellenablassrichtung the pulley 5, whereby the cable 10 is wound onto the pulley 5 and the in FIG. 3 exhibited exhibitor mechanism is set in motion.

In particular with a roller shutter armor consisting of tanks such as the roller shutter curtain 3 must be attached to the winding shaft 2, that after complete draining of the curtain further rotation of the winding shaft in Ablassrichtung is possible and that at least by such an angle that it Engage and operate the drive train of the additional function is sufficient.

In this regard is on the FIGS. 14 and 15 referenced in which a Behangbefestigungsvorrichtung 6 is shown, with which the curtain 3 is fixed to the winding shaft 2. In this case, the hanging-fastening device 6 has winding-shaft-side two sleeves 36 which are spaced apart from one another and pushed onto the winding shaft, on each of which a stop projection 34 protrudes in the radial direction of the winding shaft 2. Between the two sleeves 36 and the stops 34 while a Behangaufnahmeschlitten 31 is rotatably received, which is rotatably received with runners sections in circumferential grooves of the sleeves 36 relative to the winding shaft 2. On the Behangaufnahmitten 31 2 projecting driver or counter-attacks 35 are formed in the axial direction of the winding shaft, which, as in FIG. 14 shown in the wound on the winding shaft 2 Behang 3 or not yet completely unwound curtain 3 are in abutment with the projections 34 and, if the curtain 3 is completely unwound, out of engagement with the protruding stops 34, which in a further rotational movement of Winding shaft in Behangablassrichtung be turned away from the attacks. The curtain 3 is received with its last slat 30 in a hanging attachment eye 37, which is connected via a Behangabschwenkflügel 32, 33, 37 pivotally connected to the rotatably received Behangaufnahmigungs 31.

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