The clipper arm fastening section is displaceably guided into a frame component in a direction of pressure or traction force induced by the pressure or traction unit, where the frame component is attached to a building. The exhibitor arm fastening unit is firmly fixed in the frame component during deviation and pivoting up of a pivoting section.

Description

The invention relates to a building-opening shading device with a displayable guide rail according to the preamble of claim 1 and claim 2.

Building opening shading devices of this type have a deployable guide rail arrangement which has two lateral guide rails for a curtain which can be pulled up and down in front of the building opening. In this case, the guide rail arrangement can be pivoted away from the building opening either as a whole or at least with a lower pivoting section about an upper pivot axis. For this purpose, at least one exhibitor arm is provided below the articulation axis of the pivoting section, which engages with an engagement section on the pivot section and is fastened to the building opening side with a fastening section spaced therefrom.

Such Ausstellerrolladen is for example the FR 2875532 B1 refer to. The pivoting portion of the local shuttering comprises, in addition to the guide rails, the roller shutter box and the winding shaft of the curtain received therein, which are suspended as a whole in an articulated manner. For swinging either a telescoping arm exhibiting a compressed air cylinder is provided as a drive or a pivotable arm exhibitor, which is provided with a spring acting as an actuator. The one end of the exhibitor arm is hinged to the guide rail, the other end below the pivot axis of the pivot portion of the building opening. If a locking device is released, the energy of the air cylinder or the pivot spring, whereby the pivot portion is issued discharges. For swiveling the pivoting section, a cable pull arrangement is provided, wherein a cable pull is connected to one end with a lower slat of the roller shutter curtain and other ends with a tension spring, which is in the applied position of the swivel section when the shutters are not extended and after the roller shutter has been lowered , is relieved. After swinging the pivoting portion drained shutters the tension spring is partially under load and works when rewinding the Rolladenbehangs on the winding shaft against the air cylinder, causing the total pivoted shutters back to the Building opening is used.

In the variant with the spring-loaded swivel arm this is connected at not pivoted-down position of the pivoting portion and not yet fully drawn drapery with its one end hinged and slidable on the guide rail. If the locking device is released, this end slides down along the guide rails, whereby the pivoting portion is issued. When reassembling the blind with flared pivot section, the end of the swivel arm received on the guide rail is taken along by the lowermost slat of the blind, whereby the swivel section is pivoted against the spring force, and wherein the end of the swivel arm after reaching a certain extension height of the blind curtain from the bottom slat is decoupled and the locking device is locked again, so that the curtain can be completely raised.

In the in the FR 2875532 B1 proposed shutter, the locking device is subjected to a heavy load, since it must constantly prevent against the energy stored in the drive and return springs and / or the air cylinder, the pivoting of the pivot portion, as long as it is held in its closed position. Furthermore, relatively voluminous components are necessary on the sides of the building to be covered by the shutter (compressed air cylinder, tension and Torsionsfedem), which prevent a visually appealing structure of the shutter.

Also the EP 1 942 246 A2 shows a generic blinds. However, here the pivoting section only comprises in each case one lower, pivotable leg of the guide rails. As a drive for the exhibitor, or the swivel portion while a spindle screw acting on a spindle motor is provided below the pivot axis. On the threaded spindle, a nut is arranged rotationally fixed, which is hingedly connected to one end of a pivotable display arm. The other end of the exhibitor arm is pivotally received on the window frame. If the spindle motor is actuated, the mother rotatably mounted on the threaded spindle moves along the spindle, whereby the Ausstellbewegung, so the pivoting down or pivoting of the pivot portion is performed. Here, the threaded spindle must be swung together with the spindle drive, so that the spindle drive itself must articulate on the roller shutter box or the like, the joint is heavily loaded and caused by the lying in the field of view of the user spindle drive unsightly visual appearance or voluminous covers must be present.

A Ausstellerrolladen with a basically the same drive via a threaded spindle and rotatably arranged on a mother, to which an issuer arm arrangement is added, shows the German utility model DE 296 147 42 U1 , in which case a telescopic arm is provided with pressure medium actuation supportive. The pivoting takes place on the performance of the spindle drive and the telescopic arm, whereas the swinging back the dead weight of the shutter is received by the telescopic arm and the spindle drive operates against the telescopic arm.

Furthermore, the shows DE 39 00 745 A1 a displayable shutters, in which case the guide rails are accommodated in a cam with spiral guide curves with its upper end and the cam is coupled via a coupling with the winding shaft of the shutter. Here, however, the issuing does not take place via an exhibitor arm provided below, but in that the guide rails accommodated with their upper ends in the helical guide track forcibly follow the guide track when the cam is rotated and are articulated at an articulation point at the bottom of the roller shutter box. Due to the unfavorable lever, high forces act on the cam and - via the clutch - the winding shaft or the winding shaft drive motor.

Finally, the German patent specification discloses DE 845 919 a shutter in which the winding shaft acts as a torque source for the Ausstellermechanismus. For this purpose, a coupling is provided there, with which a cable acting as a drive train for the Ausstellermechanismus cable can be coupled with drained curtain to the winding shaft. The cable engages via a pawl to a scissors mechanism formed from two articulated exhibitor arms, over which the exhibitor can be issued.

Proceeding from this, the present invention is based on the object, an exhibitable building opening shading device, in particular a roller shutter to provide with improved Ausstellermechanismus.

This object is achieved with the features of claim 1 and the features of claim 2.

In the building-opening-shading device according to the invention, a torque source is provided above or at the level of the articulation axis, and a drive train for transmitting an output power emitted by the torque source for pivoting the pivoting portion to the exhibitor arm arranged below the articulation axis, wherein the drive train is constructed such that that during the pivoting back of the pivot portion of its own weight is transmitted to the torque source, or is useful as drive power for pivoting back. In this case, a drive coupling is advantageously provided to torque coupled to couple the drive train with the torque source and connected to the drive coupling, between the arm and the drive coupling force-transmitting pressure or traction means with which the distance between the arm and the torque source can be bridged. The arm of the exhibitor is fastened or attachable with its fastening section on the building opening side, i. for example, on a window frame or a frame profile of the shutter.

The invention thus embodies itself in a combination of the generic and the above features according to the invention mentioned above, alone or in combination with each or several of the features described below or the claimed features.

It is preferred if the exhibitor arm is designed as a pivoting arm. In this case, the drive train for converting the force transmitted from the pressure or traction means in a pivoting moment of the arm exhibitor and vice versa according to a first aspect of the invention on a cooperating with the pressure or traction means and the arm exhibiting Ausschwenkanordnung. Preferably, the issuer arm is hinged building opening side at its attachment portion.

The Ausschwenkanordnung comprises according to the first aspect of the invention, a scissor arm, which then with a Scissor-arm attachment portion is attached building opening side, preferably on the frame member, and spaced therefrom hinged to the issuer, more preferably in a region between the mounting portion and the engaging portion of the exhibiting arm. The engaging portion of the exhibitor arm may then be at its other end. Instead of the scissor arm, however, a sliding stop would be conceivable to move the exhibitor arm in the pivoting direction. In this case, either the sliding stop or the attachment portion of the issuing arm could be displaceably guided, and the counterpart be received in a stationary manner at the building opening.

The exhibitor arm attachment portion may be fastened to the pressure or traction means and displaceably guided in the direction of the compressive or tensile force which can be introduced via the pressure or traction means, preferably on or in the frame component, the scissor arm attachment portion then being displaced during the deceleration. and tilting the pivoting section is fixed in place, preferably on or in the frame member. In order to fixedly fix the scissors-arm attachment portion during pivoting down and pivoting of the pivot portion, the scissor-arm attachment portion may either be fixedly connected to the frame member or provided on or in the frame member a stop against which the scissor-arm attachment portion during the down and Zuschwenkens the pivot portion is pressed.

Alternatively, the scissor-arm attachment portion attached to the pressure or traction means, preferably hinged and guided in the direction of the pressure or traction via the compressive or tensile force compressible or tensile force, preferably in the frame member, wherein the exhibitor arm mounting portion during the Ab and tilting the pivot portion is fixed in place, preferably in the frame member. In order to fixedly fix the exhibitor arm mounting portion during the pivoting down and pivoting of the pivot portion, the exhibitor arm mounting portion may either be fixedly connected to the frame member or provided on or in the frame member a stop against which the exhibitor arm mounting portion during off and Zuschwenkens the pivot portion is pressed.

Advantageously, characterized in that the torque source is mounted above or at the level of the pivot axis and connected via a drive train with the exhibitor is, on the one hand be avoided, that on the sides of the building opening to be covered voluminous drive elements must be attached, whereby the visual impression of the building opening shading device is particularly favorable. On the other hand, it is advantageous that the drive train provided for transmitting the drive power from the torque source to the arm exhibiting pivoting back of the pivoting section to the building opening towards the torque source transmits the dead weight of the pivoting portion and thus usable as drive power for pivoting back so that when swinging back no or only a small drive power of the torque source is needed, or only against the weight of the pivoting section something must be countered, so that does not swing back unchecked.

An expansible guide rail arrangement according to the invention is a guide rail arrangement with two side guide rails for guiding the curtain during winding or draining, which at least with a lower pivoting portion about an upper pivot axis of the building opening are swung down, the guide rails so either swung away from the building opening away or have a swung away from the building opening portion.

In this case, the building-opening shading device advantageously has a frame component which can be attached to the building or to the building opening, on which the exhibiting arm is articulated. In this case, the exhibitor arm is preferably accommodated in the frame component at least with its attachment section, in which an outlet opening is provided for the exhibitor arm, from which the issuer arm is led out to the pivot section, wherein the frame component is penetrated by a passage opening connected to the outlet opening, through which the Drive train or the pressure or traction means is guided by the exhibitor arm in the direction of the torque source.

In the non-flared condition of the pivoting section, in the case of an arm designed as a swivel arm, the swivel section can abut against the frame component if the swivel arm can be sunk in the outlet opening in the frame component at least so far that the swivel section comes into abutment with the frame component. As a result, the exhibitor arm is in the unissued state of the Can no longer see the pivoting section from the outside, so that the appearance of a closed roller shutter profile results, without further, the optical impression disturbing components protrude. But this is not only in terms of the visual appearance, but also on a weather protection of the moving parts, namely the exhibitor advantage.

It is particularly preferred in this case if the frame component adjoins a roller shutter box or on a box surrounding a winding shaft of the building opening shading device and the passage opening passing through the frame component opens into the roller shutter box, preferably in the region of a side part of the roller shutter box. In this case, the frame member not only in the non-flared condition of the pivot portion include the exhibitor arm together with the swivel section weatherproof and opaque, but together with the roller shutter box and the drive train include weather and opaque when the torque source is included in the roller shutter box, so that here too offer significant advantages in terms of reduced error rate.

The torque source used here is a drive motor with an output shaft or, for example, a manually operated belt via which, for example, a pulley serving as a drive coupling of the drive train is driven. However, it is particularly preferred if a rotationally driven winding shaft serves as the torque source, to which the curtain is attached, or a motor drive of the winding shaft. For this purpose, the drive coupling may further comprise a coupling element, via which the disc or pressure chain can be coupled and decoupled with the winding shaft.

The drive coupling of the drive train may have a torque transmitting coupled to the torque source disc, which is rotatably mounted in particular coaxially to a rotational axis of the torque source, in particular on the side part of the roller shutter box. As a traction device can then serve up to the disc and unwound tailed cable. In this case, advantageously, a deflection roller may be provided to direct the cable into the mouth of the passage opening. Cable according to the invention means rope or chain hoist, under disc here any suitable shaft or disc is called, even hollow shafts or discs.

Alternatively, the drive coupling of the drive train may have a torque-transmitting coupled to the torque source print chain, which is guided in an arc portion about an axis of rotation of the torque source, and as a pressure medium pressure-transmitting to the pressure chain coupled push rod. The pressure chain can in turn be received with its end on the circumference of a rotatable disc, which can be coupled torque-transmitting with the torque source. Alternatively, the print chain can also be guided in a torque-transmitting manner with the torque source coupled in an arcuate path. In order to direct the pressure chain in the mouth of the through hole, further guides may be provided.

To the pulley respectively the other guides the distance of the mouth is independent of the diameter of the pulley or the sheet guide. The diameter of the pulley or the sheet guide can be chosen freely and adapted to the desired Ausstellgeschwindigkeit or to the torque source and its performance, so that no intermediate gear stage is necessary.

Preferably, the drive coupling is constructed so that the drive train and the winding shaft are forcibly decoupled, as long as the curtain is not completely worn, and only then engaged. For in pivoting sections, which do not include the entire guide rail, but only lower pivot leg of the guide rails, the blind can often not be moved with flared pivot section, because the guide makes a kink on the pivot axis. This can be achieved by the coupling element or the drive coupling is constructed so that the drive train and the winding shaft are forcibly decoupled via the coupling element when the winding shaft covered at a predetermined location of a position of the curtain, so for example the top shutter roller bar of a roller shutter is, and otherwise forcibly coupled torque transmitting when the coupling element thus switches in response to whether the position of the curtain rests against the winding shaft and thus ultimately in response to whether the curtain is unwound.

Both in the development with cable as well as in the training pressure chain, the pivoting portion can be provided on both sides or both sides under both guide rails with an exhibitor, the exhibitor could also under a Cross member may be provided at the lower end of the exhibitor or pivot section. For actuating an exhibitor supported on both sides, two drive trains can be provided which can be coupled with the same torque source. If the exhibitor arm is to be provided below in the cross member, the development of the invention with cable is preferred because the exhibitor arm in this case is easy to connect by cable, since only a pulley at the corner of the cross member is necessary.

In a further preferred embodiment of the invention, a locking unit is interposed in the drive train for locking and unlocking the pivoting section such that upon actuation of the drive train in the pivoting direction, first the pivoting section is unlocked before pivoting begins, and when pivoting is first performed, the pivoting is carried out. before the pivoting section is locked. For explanation is already here on the FIGS. 7 and 6 referenced, which show in two different embodiments of the invention, the locking position of the locking unit on the FIG. 8 , which shows an unlocked position of the locking unit in which the exhibitor assembly is not yet pivoted, and on the Figures 2 and 5 in which an unlocked position of the locking unit is shown with pivoted exhibitor assembly.

As a result, it is possible to provide a safeguard against unwanted lifting of the pivoting section, be it due to wind load or during a break-in attempt. In this case, an undercut latch receiving opening may be provided on the building opening side facing the pivot portion, wherein the locking unit building opening side is preferably received in the frame member, and on its side facing the pivot portion has a latch hook which engages behind the undercut latch receiving opening in the locked position and in the unlock position does not fall behind.

Advantageously, the locking hook alone or the locking unit is biased to the blocking position and provided in the drive train a game, so that when the pivot portion and relieved drive train, the biasing force biases the latch hook alone or the locking unit total from the unlocked position into the blocking position, and at Onset of actuation of the powertrain first, the locking hook alone or the locking unit as a whole on the one hand and the exhibitor arm attachment portion or the scissor arm attachment portion on the other hand to move towards each other, wherein the locking unit has a stop for the exhibitor arm-mounting portion or the scissor-arm mounting portion, when reached traction between the pressure or traction means and the Ausschwenkanordnung adjusts. The bias voltage can be achieved via a biasing spring or alone by the weight of the locking unit or the latch hook. The locking unit or the latch hook can also be provided with an additional weight.

The locking hook can be attached to the locking unit in a positionally and rotationally fixed manner and the locking unit can be slidably received on the building opening side. In this case, the locking unit can then have a deflection roller over which the cable serving as a traction device is guided. The cable may be connected to the slidably guided scissor arm attachment portion, wherein the locking unit is preferably arranged below the scissor arm attachment portion, so as to make its weight usable as a biasing force.

The latch hook may alternatively be received stationary and articulated, wherein it is connected on the opposite side of the joint with a rocker arm, or has a Kipphebelabschnitt. The stationary during the pivoting of the pivot portion fixed scissor arm attachment portion or exhibitor arm mounting portion is slidably received between the locking position and the stop on the locking unit against the rocker arm, for example in a guided in the locking unit slide.

In the following, reference will be made to a second aspect of the invention. Again, a torque source is provided above or at the level of the articulation axis of the pivoting section, and also a drive train for transmitting an output power outputted from the torque source for swinging the pivotal section to the arm and swinging back the dead weight of the pivotal section to the torque source the self-weight resulting torque or a force resulting from its own weight.

However, instead of having an engaging portion engaging on the pivoting portion but not fixedly connected thereto and a mounting portion spaced therefrom, the arm according to the second aspect of the invention is on the one hand provided with a pivot-side joint portion connected to the pivot portion and on the other hand connected to a building-opening-side hinge portion building opening side. By means of the articulated connection of the pivoting section with the arm of the exhibitor and thus the connection of the pivoting section via the arm and the drive train with the torque source succeeds over the structure according to the above-described first aspect of the invention with an arm exhibitor, which acts on the pivoting portion only with an attack section, Thus, not connected to the pivoting portion, a further simplification of the drive train, or the mechanism required for issuing the exhibitor arm, as will be explained in more detail below.

As in the first aspect of the invention explained above, the torque source is located above or at the level of the articulation axis, the drive train bridging the path between the torque source and the exhibiting arm located thereunder, and the torque from the torque source into a force necessary to deploy the exhibitor arm implements. This in turn results in the advantages that voluminous drive elements can be avoided on the sides of the building opening to be covered, so that the visual impression of the building opening shading device is particularly favorable. On the other hand, in turn, the weight of the pivot portion can be used as drive power for swinging back, so that when pivoting back no or only a small drive power of the torque source is needed, or just against the weight of the pivot portion something must be countered, so this does not swing back unchecked.

In addition, however, can be characterized by the fact that the arm is connected with its pivot portion-side hinge portion with the pivot portion, a positive coupling of the pivot portion with the exhibitor with the torque source connecting tension or pressure medium, with additional no Ausschwenkanordnung is necessary to swing out the exhibitor. For when the building-opening-side hinge portion is slidably guided in the direction of the compressive or tensile force introducible via the pressure or traction means and the pivot portion-side hinge portion of the exhibitor with the pivot portion fixed or movable only in the context of a game necessary for the operation of a below to be described locking unit game at the pivot portion is fixed, a swinging out of the pivot portion results from its non-pivoted position forcibly.

For exhibiting a force must be exerted on the building-opening-side hinge portion of the exhibitor arm in one direction, which extends at least predominantly component to the pivot portion side hinge portion of the exhibitor. In other words, when pulling on a cable acting as a pulling means on the building opening side guided received hinge portion of the exhibitor, the exhibitor will be arranged so that its pivot portion side hinge portion is arranged in the non-flared state of the pivot portion above the building opening side hinge portion. On the other hand, in a pressure rod acting as a pressure means, with which the swiveling power is transmitted from the upper-side torque source to the lower-side arm, the arm portion will be arranged so that its pivot portion side hinge portion is disposed below the building opening-side hinge portion in the non-flared state of the pivot portion on which the Pressing push rod for issuing the pivot section.

A scissor arm supporting the exhibitor arm is not necessary, so that in addition to cost advantages, a more pleasing appearance of the building opening shading device as a whole results.

If the rope acting as traction means is deflected by 180 ° over a deflection roller before it engages the building opening-side hinge section, but in a development with traction means of the exhibiting arm with not hinged state above the building opening side hinge portion arranged, pivot-section side hinge section between Building opening and swivel section housed. In the above statements regarding "above" and "below" arranged joint sections was further assumed that the exhibitor or the Austellerarme, for example, each supported with their building opening side hinge portion on a vertical frame profile and with its pivot portion side hinge portion on the frame profile belonging to the pivoting part of However, it would be equally conceivable that the exhibitor arm at the lower end of the pivoting section between a horizontally extending frame profile and connecting the lateral guide rails transverse profile of the pivot portion is disposed when corresponding pulleys for the cable or deflection means for the push rod, such as a print chain are provided. In this case, however, it is no longer possible to speak of "above" and "below" in relation to the joint sections.

Thus, according to the second aspect of the invention, the present invention is embodied in the fact that, in the case of a building opening shading device with a guide rail arrangement that can be exposed via a torque source, the pivoting section of which can be pivoted via a pressure or traction means connected between the torque source and an arm connected to the pivoting section , an articulated connection of the tension or pressure means is provided with the building opening side guided recorded joint portion of the exhibitor, wherein the exhibitor arm is in turn hingedly connected via its pivot portion side hinge portion with the pivot portion. Upon actuation of the tension or pressure means, this results in forced operation or pivoting of the pivot portion. The invention is thus embodied in these features, alone or in combination, in combination with any one or more of the features or features claimed below.

Instead of the articulated connection of the tension or pressure medium with the building opening side hinge portion of the exhibitor arm, a connection of the tension or pressure means may be provided to a block which can press with a stop surface on a counter stop surface on the building opening side hinge portion and in the same leadership, how the building opening-side hinge portion is received.

The building-opening-side joint section can be designed as a joint block displaceably arranged in the pressure or tensile force direction as a frame component which can be attached in a building opening side, to which the issuing arm is articulated. On the other hand, the pivot portion-side hinge portion may be formed as a hinge block fixedly connected to the pivot portion, on which the arm of the exhibitor is hinged with its pivot portion side end.

In particular, in a development with a likewise to the drive train coupled and operable with the torque source locking unit for locking the Ausstellermechanismus in the non-flared condition of the pivot portion, however, it may be advantageous to slidably receive also the pivot portion side hinge block in a necessary for locking or unlocking the locking unit game on the pivot portion, especially in a provided there Guide groove or recess which extends in a direction which allows a displacement of the pivot portion-side hinge portion upon the action of the force transmitted via the pressure or traction means. For example, in the case of an exhibitor arm which acts on the pivotable sections of the lateral guide rails that run vertically in the non-swung-out state, this would also be an approximately vertically extending direction in this state. Alternatively, the building opening side hinge portion could be slidably disposed in the frame member and the pivot portion side hinge portion fixedly connected to the pivot portion, however, be provided on either the building opening side hinge portion or the pivot portion side hinge portion, a guide whose length the play in the drive train or the path of the Riegelhakens between lock position and unlocked corresponds, wherein the issuer is slidably received in the guide groove via a pivot pin.

The above-mentioned locking unit is advantageously connected to the drive train and actuated with the drive train for locking and unlocking the pivot portion. In this case, the locking unit is provided so that upon actuation of the drive train in Abschwenkrichtung the pivoting portion is first unlocked before the pivoting begins, and upon actuation in the direction of first swivel is executed before the pivot portion is locked.

The necessary for locking or unlocking the locking unit game in the drive train is obtained when the locking unit has a locking hook, which engages behind an undercut latch receiving opening on the pivot portion in a locked position and must therefore be moved to unlock the pivot portion to the engaging hook length, so that the swivel section is released. Because the locking unit is coupled to the drive train or actuated via the drive train, in such a way that upon actuation of the drive train in adjacent and locked pivoting portion first unlocks the pivoting portion, or is released before the swiveling can begin and when swiveling first the swiveling is carried out before the swivel section is locked again via the locking unit.

The latch hook can be fixedly mounted on a bolt block, which is slidably received building opening side, preferably in the frame member. In this case, the locking block can be connected to the pressure or traction means and thus be displaced. For example, the latch block may be arranged below the building opening-side hinge section and have a deflection roller, over which a cable pull acting as a traction device is guided, which is connected to the sliding, guided building-opening-side hinge section. If the torque source is actuated in the swiveling direction, then the locking block and thus the - pointing down - latch hook is raised and consequently unlocks the Abschwenkabschnitt before the latch block strikes the building opening side hinge section or joint block and thereby adhesion between the exhibitor and the pull rope is made , so the swinging begins. In this case, the weight of the locking unit acts advantageously as a biasing force, which biases the locking hook for Sperrrstellung out. The bias can also be reinforced by an additional biasing spring. Even in a development in which the cable is guided over a deflection roller on the building opening side joint block and the bolt block is arranged with an upwardly facing latch hook above the building opening side joint block, such a biasing spring may be provided to bias the latch hook for Sperrrstellung out.

In a further development with a locking block, the building-opening-side joint block need not be connected directly to the pulling or pushing means when the locking block is connected to the pulling or pushing means and a stop is provided on the locking block and a counter-stop is provided on the building-opening-side joint block, wherein the locking block is received in the same guide as the building opening-side hinge portion is added so that it rests in the unlocked position with its stop on the counter-stop of the building opening side hinge portion and in the Sperrrstellung to a game in the drive train or the path of the locking hook between blocking position and Unlocking position corresponding distance from the building opening side hinge portion is spaced. For example, the latch block on a as Pressure acting push rod be attached and be located above the building opening side joint block, so that the bolt block is first lowered in actuation of the torque source in Abschwenkrichtung in the unlocked position and starts there with his stop and against the counter stop of the building opening side joint block, and then moves the building opening side joint block down , whereby the exhibitor arm pivots together with the Schenkabschnitt when the pivot-section-side hinge block fixed to the pivot portion, that is immovably mounted. Similarly, the latch block could also be located below the building opening-side hinge block, it being sufficient if the building-opening-side hinge block is penetrated or bypassed by the pull rope. The bolt block - with downwardly directed Rielgelhaken- is then raised upon actuation of the torque source in Abschwenkrichtung first in the unlocked position and hits there with its stop on the counter-attack of the building opening side joint block, which is then raised.

As an alternative to the development with a separate locking block, the locking hook can also be fixedly mounted on the building opening side slidably received joint section or joint block, wherein the locking unit then, as mentioned above, may have a provided in the building opening side hinge portion or the pivot portion side hinge portion guide groove in the the exhibitor arm is slidably received, for example via a pivot pin. The length of the guide groove corresponds to the game in the drive train or the path of the locking hook between locking position and unlock position. By the interposed locking unit can be a backup against unwanted lifting of the pivoting portion in it either by wind load or a break-in - be provided, characterized in that the drive of the locking unit via the torque source and the drive train for the pivoting portion of the exhibitor arrangement, an additional Drive or manual operation device for the locking unit can be omitted, so that the cost can be further reduced and no additional, the optics disturbing components must be mounted on the guide rails.

First, reference is made to the FIG. 1 , This is a generally designated 1 blinds shown, which in a roller shutter box 7 with side panels 8 recorded winding shaft 2 ( 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 , which should be included here.

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 received, so that the swing-leg of the guide rails 4a, 4b, in the uninhibited state congruent to 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 to recognize. 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 11a for the 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 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, 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 a sliding guide 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 one of the latch hook 19 corresponding portion of the swing-leg of the guide rails 4a, 4b each have an undercut Latch receiving opening on which of 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 designed scissor arm mounting portion 16, if on the traction cable 10 formed as traction 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 rope Thus, after starting the bolt stopper portion 18 against the scissor arm mounting portion 16, 10 results in spreading out the scissors formed by the scissor arm 13 and the exhibitor arm 12, the arm 12 issuing from the scissor arm 15 formed as a rotatable rubber engaging portion on the underside of the pivot legs of the guide rails 4a 4b and thus acts on the pivoting section 4 of the roller shutter 1.

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. Figures 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 to the bolt stopper portion 18 and from there via the scissor-arm attachment portion 16 and the scissor arm 13 and the exhibitor arm-mounting portion 14 to the issuer 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 underside of the scissor mechanism 13 formed by the exhibitor arm 12 and the joint 13a articulated thereto via the joint 13a, the scissor arm 13 is articulated on its scissor arm attachment section 116, which are except for one for actuating the lock, essentially supports a small path ( 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 has a latch block 118 in which the latch 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 driveline with traction cable explained in more detail, which also in the below to be explained, in the FIG. 16 used powertrain is used.

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 an overall view of the roller shutter 1, since the curtain on the swivel joints of the swiveling section 4 would have to follow a bend in the guide groove of the guide rails 4a, 4b, if it were to move during the Swiveling the exhibitor 4 in operation would be.

In the present embodiment, the coupling element 9 has a generally designated 22 Abklappflügel, which is attached via a hinge 27 to a joint carrier 28, which in turn is pushed onto a laid over the winding shaft 2 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. In this case, on the folding wing 22 a projecting in the axial direction of the winding shaft 2 driving pin 26 is attached, which, as 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 36 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 30 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 35 and the stops 34 while a Behangaufnahmschlitten 31 is rotatably received, which is rotatably received with runner sections in circumferential grooves of the sleeves 34 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.

In further reference is made to the FIG. 16 , Therein, a roller blind designated as a whole by 201 is shown, which has a winding shaft 2 received in a roller shutter box 207 with side parts 208 (FIG. FIG. 2 ), on which a roller shutter is taken up and unwound. To guide the roller shutter, the 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 each with a frame member 11 extending from the shutter box 7 to the lower edge of the respective swing-out leg of the guide rail 4a, 4b, 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 shutter 201 is mounted with its two frame members 11 and the roller shutter box 208 on a window frame 0. The swivellable guide legs are articulated to the stationary, upper sections of the guide rails 4a, 4b via a swivel joint which can be inserted into the profiles of the guide rail legs or halves. Such an exhibitor joint is the subject of its own utility model DE 20 2008 013 422 , which should be included here. Again FIG. 1 It can also be seen, in each case an issuer arm 212 is provided for the two swing-leg of the guide rail assembly, which is supported with its upper end the pivotable guide rail legs in the pivoted state and is received with its lower end in the frame member 11, so that the swing-leg of the guide rails 4a, 4b congruently come to rest in the non-flared condition of the pivoting section 4 on the two frame components or frame profiles 11.

The exhibitor arms 212 in each case penetrate a through opening designated by 11 a in the frame profiles 11 and have, as in particular from the synopsis of Figures 1 and 2 shows, in a guide groove or a guide channel behind the passage opening 11a in the frame member 11 guided, building-opening-side hinge portion 214. This building-section-side hinge portion 214 is formed as a guided in the guide groove of the frame member 11 block 214 to which the respective arm 214 is articulated. At the other, ie the upper end of the exhibitor arm 212, a joint block 215 functioning as a pivot-section-side joint section 215 is provided, on which the issuer arm 212 is articulated. The joint block 215 is fixedly connected to the respective pivotable guide rail legs.

For raising and lowering or for swinging back and forth or exhibiting the pivoting section 4 of the exhibitor arrangement, a drive train 9, 5, 10, 18, 19, 20, 214 is provided which supports the above-described drive coupling 9, 5 (FIG. FIGS. 9 to 11 ) for coupling the drive train 9, 5, 10, 18, 19, 20, 214 to the winding shaft 2 acting as a torque source 2 of the shutter, such as a slidably guided, building-opening-side hinge portion 215 connected Traction cable 10.

The traction cable 10 is guided by an extending along the frame profile 11 chamber upwards and there via a pulley on a rotatably received pulley 5, which has a driving cam 24 which can be operated via a connected to the winding shaft 2 coupling element 9. The chamber in this case adjoins the guide channel for the joint block 214 or forms with it a passage of the same cross-section through the frame component.

The actuation or circuit of the coupling element 9 takes place in the manner described above. If the curtain is unwound from the winding shaft 2, so at the end of unwinding the last position of the curtain releases the pretensioned as outwardly hinged wing 9 coupling element 9, which projects with its projecting in the axial direction of the winding shaft 2 driving pin 26 against a cylindrical portion 24a rotatably mounted on the side portion 208 of the roller shutter box 207 mounted pulley 5 runs and migrates in a further actuation of the winding shaft 2 in the unwinding along this cylindrical portion 24a until it meets the drive cam 24 and the pulley 5 entrains in further operation. This pulls on the cable pulley 10 connected to the cable pulley 5, so that first of all a latching block 18, 19, 20, which is displaceably received in the side frame profile 11, the bolt hook 19 fastened thereto and the guide pulley 20 also attached thereto, is raised, until the latch block 18 abuts with a top abutment surface against a bottom counter stop surface on the building opening side joint block 214 received in the same frame in the side frame profile 11. The length of the rope 10 is adjusted so that the locking unit 18, 19, 20 is at least raised so far before it abuts against the joint block 214, that raised in the starting position, an undercut on the pivot portion 4 engaging behind latch hook 19 with its entire hook length that the undercut is no longer engaged.

If the winding shaft 2 is actuated further in the unwinding direction of the blind after unlocking or unlocking the pivoting section 4, the locking block 20 pushes the building-opening-side joint block 214 upward, which due to the fixed attachment of the pivoting-section-side joint block 215 to the associated, pivotable leg of the respective guide rail 4a, 4b forcibly to one Issuing the articulated between the two joint portions 214, 215 exhibitor arm 214 and thus to a pivoting of the Abschwenkabschnitts 4 leads.

In the FIGS. 18 to 20 A further embodiment of the invention is shown with a modified variant of a drive train 9, 105a, 105, 110, 314, 319, 315, 318, 320 for an issuer arm 312 and for a locking unit 318, 319, 320, wherein the locking unit 318, 319 , 320 and the issuer arm 312 have been adjusted accordingly.

In this variant, instead of the pulleys 5 of the above-discussed embodiment, side pulleys 108 are provided instead of the pulleys 5 rotatably received on the side parts 208, which guides have a guide concentric around the winding shaft 2 for a pressure chain 105 attached to a chain pulley 105a. The guide is denoted by 117 a and defines an annular channel between it and the chain plate 105 a, in which the pressure chain 105 fastened on the chain plate 105 a, which is received rotatably on the side part 108, is guided. If the follower pin 26 engages the chain disk 105a, then the print chain is guided via the guides 117a and further guides 117b, 117c in the direction of the longitudinal opening penetrating the side frame component 11. In this longitudinal opening or in this the side frame member 11 penetrating channel is arranged in this embodiment, a push rod 111 which is connected at its upper end to the print chain 105 and at its lower end with a building opening side hinge portion of the issuing arm 312 serving block 314, at in turn, the exhibitor arm 312 is articulated. The exhibitor arm 312 in this case has at its lower end arranged for pivoting section 4 a pivoting-section-side joint section 315 which is connected to the swing-down leg of the associated lateral guide rail 4a, 4b.

As in particular from the FIG. 19 It can be seen that is hinged to the guided in the side frame section 11 joint block 314 not only the issuer 312 and the push rod 110 attached, but also provided a latch hook 319, which points with its free end up and in the locked position an undercut of a groove on the swinging leg the associated guide rail 4a, 4b engages behind. Will now from above on the print chain 105 and the Pulling rod 110 is pressed on the joint block 314, and the joint block 314 thereby displaced downwardly, so the latch hook 319 also moves downwards, namely until it is moved with its full hook length from the area behind the undercut.

In order to prevent that in downwardly moving joint block 314 is already a deployment movement of the pivot portion 4 begins, which would inevitably result in a stationary articulation of the 3190 exhibitor with the pivot portion 4 forcibly, has the pivot portion side hinge portion 315, over which the exhibitor arm 312 with the swinging Leg of the respective guide rail 4a, 4b is not connected to a fixed joint, as on the building opening side hinge portion 314, but a guide groove 320, in which a pivoting portion facing the lower end of the 3190 exhibitor arm attached hinge pin 318 is slidably and articulated received. The length of the guide groove 320 corresponds to that in the drive train for unlocking the hook from its located behind the undercut position game. Thus, while the building-opening-side hinge block 314 travels downward, the hinge pin 318 also initially travels downward along the guide rail 320 before abutting against a wall of the hinge block 315 secured to the pivot section 4 at the lower end of the guide rail 320. In this situation, the locking hook 319 is then in its unlocked position, that is, it can be pulled out of the groove in the swing-leg of the respective guide rail 4a, 4b. Upon a further pressure on the pull chain 105 and the pull rod 110 on the building opening side joint block 314, there is therefore a forced swinging of the pivot portion 4, because the guided downward movement of the joint block 314 on the exhibitor arm 312 and the pivot portion side hinge block 315 in a deployment movement of the Swivel portion 4 is implemented without the locking hook engages behind the undercut in the associated groove on the pivot portion 4.

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