The invention relates to a strand element with an elongate strand, with a plurality of coupling devices distributed in the longitudinal direction of the strand for coupling and / or latching with a counter-device corresponding to the coupling devices.

Such a strand element is for example off DE 697 12 619 T2 or known as a chain or a rack. Such chains or racks are designed for use in combination with a gear.

A disadvantage here is that the usability of such a strand element is limited for alternative and / or additional fields of use.

It is therefore the object of the invention underlying a strand element of the type mentioned in such a way that the functionality and / or usability are improved.

The problem underlying the invention is achieved by a strand element of the type mentioned, in which the coupling means and the counterpart device for limiting a displacement and / or for fixed fixing of the counter-device in relation to a separate profile strand and / or the strand element are formed the coupling device has a receiving region for receiving at least one counter device, and the strand has at least one guide device for stationary arrangement of the strand on a separate profile strand, wherein the guide device is designed to cooperate with a correspondingly formed profile groove of the profile strand extending in the longitudinal direction of the profile strand, wherein the guide device has a clamping side and two guide sides and is designed to align the longitudinal axis of the strand in the longitudinal direction of the profile strand. It is advantageous that the strand element is connectable due to the guide device with a separate profile strand, resulting in the profile strand in a simple manner and can at least partially assign transversely extending to the longitudinal direction of the profile strand coupling devices. Profile strands are usually produced by means of an extrusion process, with which a certain and over the entire length of the profile strand resulting cross section can be specified. However, if at least partially transversely to the longitudinal alignment of the profile strand extending profile sections provided, the production is previously associated with a considerable additional effort. This additional effort is considerably reduced by means of the strand element according to the invention. After the extruded profile has been produced by a conventional extrusion process and optionally cut to the required length, a coupling device arranged at least partially transversely to the longitudinal direction can be provided in a simple manner due to arranging the strand element on the profile strand and in its longitudinal direction. As a result, a setting of a counter-device on the profile strand in the longitudinal direction of the profile strand is made possible. In this case, the guide device of the strand element enables or facilitates stationary fixing and / or alignment of the strand element in the longitudinal direction of the profile strand. Preferably, the longitudinal direction of the strand and / or the profile strand results due to an elongated design of the strand and / or the profile strand. The elongate formation may be linear and / or curved.

According to a further embodiment of the strand element, the guide device extends in the longitudinal direction of the strand. Preferably, a plurality of guide means in the longitudinal direction of the strand, in particular evenly distributed. As a result, a counterpart device designed correspondingly to the coupling device can be fixed at different points in the longitudinal direction of the profile strand. Preferably, a counter-device can interact at different points in the longitudinal direction of the profile strand with a coupling device. In particular, the coupling device and the counter-device cooperate for limiting a displacement path and / or for the fixed fixing of the counter-device in relation to the profile strand and / or the strand element.

Preferably, the guide means is adapted to transfer forces from the strand to the tread strand. As a result, forces acting on the coupling device via the counter-device can be transmitted to the extruded profile, the danger of a change in position of the strand element being sufficiently prevented on account of the guide device.

According to the invention, the guide means is designed to cooperate with a correspondingly formed in the longitudinal direction of the profile strand extending profile groove of the profile strand. As a result, a connection of the strand element with the profile strand can be produced in a simple and effective manner. In particular, the strand element can be inserted into the profile groove.

The strand may have several, in particular evenly and / or distributed over the entire length of the strand, members. Accordingly, the strand may be formed as a limb strand and / or the strand element as a, in particular flexible, chain. Preferably, the linkage is fixed in position connected to the rail. The limb strand may have a, in particular rigid or flexible, strand. Preferably, each member is assigned a guide device and / or a coupling device. As a result, sufficient guidance of the strand element on the profile strand, in particular in a profile groove, can be realized. Preferably, the coupling device and / or a single member each have a projection, in particular a plurality of projections on.

According to a further embodiment, the guide device and / or the links each have a clamping side. Furthermore, the guide device and / or the links can each have two guide sides which are remote from one another and extend transversely, in particular at right angles, to the plane of the clamping side and in the longitudinal direction of the strand. Here are the guide pages for interaction with the profile groove. When connecting the strand element with the profile groove, the clamping side faces a groove bottom of the profile groove. Here, the clamping side is at least partially in contact with the groove bottom. The guide sides are facing two mutually facing side walls of the profile groove in the connection of the strand element with the profile. The side walls come at least partially in contact with the guide pages. In particular, the outer surfaces of the guide sides abut against an inner surface of two mutually facing inner sides of the profile groove. Preferably, the profile has two mutually facing legs, which are associated with the side walls at an end remote from the groove bottom end. The free ends of the legs are facing each other, preferably extending the legs parallel to the groove bottom plane. In the connection of the strand element with the profile groove include the Leg at least partially the guide sides and / or the links in a side facing away from the groove bottom area. Especially because of the interaction the guide sides with the inner sides of the profile groove, the clamping side with the groove base and the legs of the profile with a corresponding recess formed to the legs results in a sufficient guidance and / or attachment of the strand element in the profile, in particular transversely to the longitudinal orientation of the profile strand.

According to a development, the links each have a functional side, which faces away from the clamping side. The functional side is preferably part of the coupling device. In particular, the functional side in the profile groove mounted state is remote from a groove bottom of the profiled groove, so that an interaction of the projection with the counter device, in particular a fixing element, is made possible. The clamping side, however, in the mounted state facing the groove bottom of the profile groove. On the clamping side can be arranged in the longitudinal direction of the strand extending clamping web.

Preferably, the clamping web has at least one first ramp and / or a pedestal, wherein preferably the ramp has a sloping from the pedestal in the longitudinal direction of the strand inclination. While the pedestal rests in the mounted state on the groove bottom of the profile groove, the ramp can facilitate insertion of the strand element, in particular of the links, in the profile groove. Such ease of assembly results in a mounting direction or insertion direction, in which the ramp is introduced in front of the pedestal of the same member in each profile in the profile. In particular, a second ramp facing away from the first ramp is provided. It is advantageous that the ease of assembly results in both a first mounting direction as well as in a second mounting direction rotated by 180 ° to the first mounting direction. In a flexible strand allows a ramp tilting of the member, so that the ramp on the profile groove, in particular the groove base, rests and the pedestal is spaced from the profile groove.

According to a further embodiment, the coupling device has a receiving region for receiving at least one counter device, in particular a fixing element. A receiving region can be formed corresponding to the shape of the counter-device, in particular the fixing element, wherein preferably in a fixing position of the counter-device any displacement of the counter-device, in particular a displacement element along the profile strand is prevented. Alternatively, the receiving area can be designed such that the counterpart device, in particular the fixing element and / or the displacement element, is displaceable within the receiving area along the profile section, wherein, however, the travel path is limited. In particular, in a pivoting gear as a sliding element is a method of the slats and / or the Carriage along the profile rail formed as a support rail prevented due to the limited travel.

Preferably, the plurality of coupling devices and / or the plurality of receiving areas, in particular evenly distributed over the entire length of the strand. In particular, the counter-device and / or the fixing element, in particular the displacement element, moves automatically into one of the two predetermined receiving regions at a position between two predetermined and adjacent receiving regions.

According to a development, the coupling device comprises at least one projection, in particular a plurality of projections. In particular, the at least one projection is assigned to the functional side. Preferably, a receiving area is limited in the longitudinal direction of the strand by means of two spaced-apart and immediately adjacent projections. Preferably, the projections on at least one stop surface, in particular for cooperation with the counter device on. The stop surfaces act in the Festsetzposition of Festsetzelementes with the counter device, in particular the fixing element, together. The projections may be formed as webs and / or teeth oriented transversely, in particular at right angles, to the longitudinal direction of the strand.

Of particular advantage is a profile strand with a strand element according to the invention, wherein the strand element is fixed stationary in relation to the profile strand in a profile groove of the profile strand. Preferably, a profile strand for arranging a displacement element, in particular for a shading system, and provided with a channel for guiding and moving the displacement element, wherein the channel, the strand element for providing a displacement limit and / or for determining the position of the displacement element associated with respect to the channel is, and the sliding element at a freely selectable position and / or at one of a plurality of positions along the channel in terms of its displaceability is limited and / or fixable.

Preferably, the profile strand is formed as a support rail for arranging carriages and a pivoting mechanism for a vertical blind with a channel for guiding and moving the carriage and the pivoting gear.

From the DE 195 25 139 A1 is designed as a profile rail profile strand known in the carriage of the slats of the vertical blind and a pivoting gear as sliding elements are guided displaceably in the same channel. The pivoting gear has a pivot pin for arranging a crank rod, wherein the pivot pin is guided by means of a link in such a way that the crank rod in a first end position and in one of the first End position deviating second end position of the slats is arranged laterally outside the closed Behangebene. In a change from the first end position to the second end position or vice versa pivots the pivot pin and thus the crank rod from a first side of the closed Behangbene to a side facing away from the first side second side of the closed Behangebene. In addition, the pivoting gear by means of the crank rod in the longitudinal direction of the rail can be moved, whereby the lamellae are moved together or moved apart.

The disadvantage here is that the position of the displacement element along the rail can be changed at any time, since the displacement element along the channel is free to move. As a result, there is the risk of incorrect operation and / or damage to the shading system when the displacement element is moved in a position of the shading system in which this should not actually happen or is provided. For example, in the case of vertical blinds, moving and / or moving apart the slats for opening and / or closing the curtain along the support rail should not take place in the case of a closed curtain or the slats in the first or second end position. Preferably, the slats, in particular the slat surfaces, are aligned in a closed curtain substantially in the longitudinal direction or parallel to the support rail. If, however, a displacement of the lamellae carriage along the mounting rail at a closed curtain or slats in the first or second end position, this may represent a malfunction and there is a risk that the slats snagging and / or damage to the vertical blind comes.

In the extruded profile with the strand element according to the invention is of advantage that due to the channel associated with the strand element displacement of the displacement element in at least one displacement direction can be prevented. In particular, the strand element serves for fixing or setting the position of the displacement element. Preferably, a setting and / or setting of the position also means a restriction of the free travel path for the displacement element. In particular, in the formation of the displacement element as a pivoting gear and / or as a carriage for a vertical blind a displacement of the slat carriage is prevented due to a displacement of the pivot gear along the channel at a limitation of the displacement and / or a fixed position of the pivot gear. In particular, a fixing of the position of the pivoting gear and / or the lamellae carriage in the first end position and / or the second end position of the lamellae can be realized by means of the strand element.

According to a development of the profile strand, the strand element extends at least substantially over the entire length of the channel and / or the profile strand. As a result, for example, a limitation of the displacement and / or setting the position of the displacement element, the lamellae carriage and / or the pivot gear at any point along the channel feasible. Preferably, the plurality of positions, in particular for fixing the displacement element, evenly distributed in the longitudinal direction of the channel. Preferably, the displacement element, in particular the pivoting gear, at a freely selectable position and / or in one of several, in particular evenly distributed in the longitudinal direction of the channel, positions along the channel with respect to its displaceability limited and / or fixable. In the case of a plurality of predetermined positions, in particular of the swivel gear, the plurality of positions are preferably adjacent to one another directly. This results in an approximately freely selectable restriction of the travel and / or determination of the position of the displacement element along the channel.

Preferably, the strand element is inserted into the profile groove associated with the channel, wherein the strand element in the profile groove self-locking and / or by means of additional fixing means, in particular in the longitudinal direction of the profile, fixed in position can be fastened. As a result, existing profile rails can be retrofitted, in which a strand element is inserted into a suitable profile groove. As a fixing agent adhesives, screws, nails, pins and / or end caps for the rail and / or the channel can be used.

According to a further embodiment of the extruded profile, the outer surfaces of the guide sides of the links rest against an inner surface of two mutually facing inner sides of the profile groove. Preferably, the profile has two mutually facing legs which are remote from the groove bottom. This results in a simple to implement, in particular transversely to the longitudinal alignment of the profile strand and / or the strand element, solid compound of the strand element with the profile. In particular, the legs at least partially comprise the guide sides and / or the links.

Furthermore, a shading system with a profile strand, in particular a vertical blind with a profile rail formed as a support rail, with a strand element according to the invention for arranging a sliding element and with a channel for guiding and moving the displacement element of particular advantage. Here, the channel may be associated with a strand element for providing a displacement limit and / or for determining the position of the displacement element with respect to the channel, wherein the displacement element at a freely selectable position and / or at one of several Positions along the channel in terms of its displacement is restrictable and / or fixable.

Preferably, a plurality of fins are provided, wherein in each case a lamella is attached to a respective individual carriage. The lamellae are pivotable by means of the pivoting gear about its longitudinal axis from the first end position with a closed curtain in the second end position with a closed curtain and / or from the second end position to the first end position. Preferably, a pivot shaft is provided, which connects the pivoting gear with the carriage and a carriage associated with each lamella gear for rotating the slats about its longitudinal axis. In particular, the pivoting gear is displaceable in the mounting rail for moving the carriage. Preferably, the pivotable in the longitudinal direction of the support rail pivoting gear in the first end position and / or the second end position of the slats for preventing a method of the lamella with respect to the position of the pivot gear with respect to the support rail is limited and / or fixed with respect to its displaceability.

Thus, incorrect operation, snagging of the slats and / or damage to the vertical blinds due to a method of the slats along the support rail are prevented when slats or slat surfaces are aligned substantially in the longitudinal direction of the support rail.

Preferably, a sliding element designed as a swivel gear for a vertical blind for pivoting slats from a first end position to a deviating from the first end position second end position and / or from the second end position to the first end position, with a gear housing, which is for closing and / or opening the vertical blind is slidable along a mounting rail provided. At least one counter-device, in particular a fixing element, for providing a displacement limit and / or for determining the position of the swivel gear and / or a support structure with respect to the mounting rail, may be provided in the swivel gear, thereby closing and / or opening the vertical blind in the first End position and / or the second end position of the slats and in at least one direction of displacement is prevented.

It is advantageous that a displacement of the slats in the first and / or second end position along the support rail is prevented in at least one direction of displacement. Thus, a misuse and snagging of the slats and / or damage to the vertical blinds can be avoided. Preferably, the vertical blinds are opened and / or closed on the basis of a method of the slats and / or the carriages along the mounting rail. The method of the slats and / or carriage can by a method of the pivoting gear along the Can be controlled mounting rail. If, for example, the swivel gear is displaced in a first direction along the mounting rail, the swivel gear can push together the disks and / or carriages. If the swivel gear is displaced in a direction opposite to the first direction along the mounting rail, the slats and / or carriages, in particular by means of the pivot gear and / or the slats and / or carriage connecting spacers, pulled apart. In particular, opening and / or closing of the blind occurs due to a rotational movement of the slats about their respective longitudinal axis. In the case of a closed curtain, the lamellae or lamellar surfaces are aligned essentially in the longitudinal direction or parallel to the longitudinal axis of the carrier rail. When the curtain is open, the slats or slat surfaces are aligned transversely, in particular at right angles, to the longitudinal axis of the support rail. In particular, results in an open curtain, a light gap between two immediately adjacent slats. The swivel gear preferably has a support structure, in particular a gear frame and / or a gear housing. Furthermore, a sliding device for displacing the pivoting gear and / or the supporting structure along the mounting rail can be provided.

Preferably, the counterpart device and / or the fixing element in the first end position and / or the second end position of the slats assumes a fixing position and cooperates with the profile strand, in particular the support rail. The counter-device and / or the fixing element can cooperate by means of a non-positive, frictional and / or positive connection, in particular a friction connection and / or latching connection, with the profile strand or the mounting rail for fixing the displacement element. In particular, the fixing element can be pressed with a force against the support rail, so that a displacement of the displacement element along the support rail is prevented. Preferably, the fixing element is movable by means of an actuation of the displacement element, in particular of the pivoting gear, from a release position into the fixing position or from the fixing position into the release position. Thus, the function of setting and releasing is coupled with respect to the displaceability in the longitudinal direction of the support rail with the usual function of the displacement element. This eliminates in particular a separate operation for setting and releasing the pivot gear. Preferably, the usual function of the pivoting gear allows rotation of the slats about their longitudinal orientation and / or a collapse and / or moving apart of the slats along the support rail.

The counter-device and / or the fixing element may protrude out of the support structure in the fixing position, in particular in the direction of the support rail. Preferably, the fixing element in the release position is at least largely arranged within the support structure. As a result, a setting and / or release of the displacement element with respect to the mobility in the longitudinal direction of the mounting rail can be easily realized. The fixing element may be formed as a, in particular in the displacement element and / or the support structure pivotally arranged stop. Preferably, this stop cooperates with a correspondingly formed and the support rail associated counter-stop for fixing the position of the displacement element and / or the support structure. In particular, a first fixing element for fixing the position of the support structure in the first end position of the slats and a second fixing element for fixing the position of the support structure in the second end position of the slats are provided.

The swivel gear preferably has a pivot pin, in particular for fastening a crank rod. The crank rod and / or spinning rod can be rotatably connected to the pivot pin. In particular, the pivot pin is rotatable about its longitudinal axis. About a rotation of the crank rod about its longitudinal axis, the rotation of the pivot pin about its longitudinal axis. In addition, the swivel gear and / or the support structure can be moved by means of the crank rod along the support rail. Preferably, the pivot pin is coupled to a slide which is displaceable from a first end position to a second end position, which differs from the first end position, and / or from the second end position to the first end position. By means of the slider is in the first end position, the Festsetzposition of Festsetzelementes in the first end position of the slats and / or in the second end position, the Festsetzposition of Festsetzelementes in the second end position of the slats realized.

The slider may have at least one projection-like nose. In the first end position and / or second end position of the slider, the nose preferably presses the locking element into the fixing position. In particular, the slider has a first nose and a second nose remote from the first nose. Preferably, the first nose for cooperation with a pivot cover and the second nose may be provided for cooperation with a Festsetzelement, in particular in the first end position and / or the second end position of the slider.

The webs 76, 77 are transverse, here aligned at right angles to the longitudinal orientation of the pivot shaft channel 25. The fixing element 27 is pivotally mounted about the web 77. Similarly, the pivot cover 28 is pivotally mounted about the web 76. The fixing element 27 and the pivot cover 28 are aligned in a release position and in a substantially horizontal orientation of the cover 40 each substantially horizontally. In the release position, the fixing element and the pivot cover 28 are arranged substantially in the plane of the upper side 12 and / or at least substantially within the transmission housing 11. Furthermore, due to the rotatable mounting around the web 77, the fixing element 27 can be moved out of the gear housing 11 and beyond the surface of the top side 12 and / or the cover 40. The pivot cover 28 remains even when pivoting about the web 76 within the transmission housing 11th

When the slider 36 is in the first end position, the nose 39 pushes a first locking side 78 of the locking member 27 outwardly of the opening 42 and beyond the surface of the top 12. In the second end position of the slider 36, the nose 39 pushes a second Festsetzseite 79 of Festsetzelementes 27 from the opening 42 to the outside and beyond the surface of the top 12 addition. In an intermediate position of the slider 36 between the first end position and the second end position, the nose 39 cooperates with the fixing element 27 such that the fixing element 27 is arranged at least substantially within the transmission housing 11 and substantially parallel to the top 12.

Fig. 6 shows a sectional side view of a profile strand 43 with a strand element 29 according to the invention. The profile strand 43 formed here as a support rail 43 is part of a vertical blind.

In the support rail 43, the pivot gear 10 is guided displaceably in the direction of its longitudinal axis. The mounting rail 43 has a channel 75 which extends in the longitudinal direction of the mounting rail 43 and over the entire length of the mounting rail 43. In this case, profile webs 44 serve as a guide and bearing surface for the rollers 19, 20, 21 of the sliding device 18 of the swivel gear 10. The profile webs 44 extend on an inner side of the channel 75 and in the longitudinal direction of the channel 75.

The toothing 34 makes up about half the length of the worm wheel 26, while the spindle thread 35 occupy the remaining approximately half the length of the worm wheel 26. The pivot shaft channel 25 of the worm wheel 26 has on its inner surface a web-like bead 45, which extends in the longitudinal direction of the pivot shaft channel 25. A pivot shaft not shown here has a groove 45 corresponding to the groove formed so that the pivot shaft rotatably connected to the worm wheel 26 is connected.

The strand element 29 is inserted in a profile groove 46 and secured against displacement with respect to the mounting rail 43. The strand element 29 is thus fixedly connected to the mounting rail 43. The strand element 29 has a plurality of links 47 and the spacing of the links 47 defines a receiving region 48. Here, not all links 47 and receiving regions 48 are provided with a reference numeral for better clarity.

As soon as the slider 36 is in the first end position or the second end position, the first fixing side 78 or the second fixing side 79 of the fixing element 27 is pressed out of the transmission housing 11 and into a receiving region 48. In this way, a displacement of the pivoting gear 10 in the longitudinal direction of the support rail 43 at least as largely preventable that a pushing together and / or pulling apart from here not shown carriage, which are arranged displaceably in the channel 75, is prevented.

Fig. 7 shows a sectioned first side view of the pivot gear 10 in the first end position. In that regard, also to the description Fig. 3 directed. In the first end position, the nose 39 of the slider 36 is below the outer end of the second Festsetzseite 79 of Festsetzelementes 27. The two opposite outer ends of the first Festsetzseite 78 and the second Festsetzseite 79 have a greater material thickness than the area of Festsetzelementes 27 between the two outer ends. As a result, and due to the position of the nose 39 below the thickening of the second Festsetzseite 79, the fixing element 27 is pivoted due to its rotatable mounting about the web 77 from the plane of the top 12. In this way, the second fixing side 79 projects into a receiving region 48 of the strand element 29.

The first Festsetzseite 78 has at its outer end on a side facing the strand element 29 on a projection-like elevation 80, which is pivoted away in the first end position of the strand element 29 and into the pivoting gear 10 inside. The second Festsetzseite 79 has at its outer end on a side facing the strand element 29 on a projection-like elevation 81, which is pivoted in the first end position into a receiving area 48 and out of the top 12 out.

The receiving areas 48 are limited in the longitudinal direction of the strand element 29 by projections 54. Due to the projecting into the receiving area 48 survey 81, the travel of the pivot gear 10 in the longitudinal direction of the strand element 29 is limited. In this embodiment, the elevations 80, 81 each have an inclined flank on one side. In addition, in this example, a strand 49 of the strand element 29 is flexible, elastic and / or resilient. As a result, there is the possibility in a first direction of displacement of the pivoting gear 10 in the longitudinal direction of the strand element 29 that the respective elevation 80, 81 pushes the strand 49 away from the pivoting gear 10 due to the oblique flank when abutting a projection 54 at a sufficient tensile force. As a result, it is possible to skip the initially blocking projection 54 during a displacement in the first displacement direction.

In a movement of the pivoting gear 10 in a direction away from the first direction of displacement second displacement direction, however, the projections 81 acts as a pure blocking element, so that a displacement of the pivot gear 10 via the receiving area 48, in which the survey 81 engages blocked.

Fig. 8 is a cut second side view of the pivot gear 10 in the release position refer. In the release position, the slider 38 is located between the first end position and the second end position. In the release position, the nose 39 is not below the thickened outer end of the first Festsetseite 78 or the second Festsetzseite 79. Instead, the nose 39 is so at a central region of the Festsetzelementes 27 that the Festsetzelement 27 is aligned substantially parallel to the top 12 , In this case, the elevations 80, 81 are arranged such that a free displacement of the pivoting gear 10 along the strand element 29 is optionally possible in the first and second displacement direction, wherein the elevations 80, 81 do not come into contact with the projections 54.

Fig. 9 is a cut third side view of the pivot gear 10 in the second end position refer. In that regard, also to the description Fig. 4 directed. In the second end position, the nose 39 of the slider 36 is below the outer end of the first Festsetzseite 78 of Festsetzelementes 27. Due to the position of the nose 39 below the thickening of the first Festsetzseite 78, the Festsetzelement 27 due to its rotatable mounting around the web 77 from pivoted the plane of the top 12. In this case, the first fixing side 78 projects into a receiving region 48 of the strand element 29.

The protrusion-like elevation 80 of the first fixing side 78 is pivoted into a receiving area 48 and out of the upper side 12 in the second end position. The projection-like elevation 81 of the second fixing side 79 is pivoted away from the strand elements 29 in the second end position and into the pivoting gear 10.

Due to the projecting into the receiving area 48 survey 80 of the travel of the pivot gear 10 is limited in the longitudinal direction of the strand element 29. Due to the sloping flank on the elevation 80, in a first direction of displacement of the pivoting gear 10 in the longitudinal direction of the strand element 29, the possibility that the respective elevation 80 due to the oblique flank when abutting a projection 54 at a sufficient tensile force the strand 49 of the pivot gear 10th push away. This makes it possible to skip over the initially blocking projection 54 during a displacement movement of the pivoting gear 10 in the first displacement direction.

In a movement of the pivoting gear 10 in a direction away from the first direction of displacement second displacement direction, however, the survey 80 acts as a pure blockade element, so that a displacement of the pivot gear 10 via the receiving area 48, in which the survey 80 engages blocked.

Fig. 10 shows a sectioned further side view of the pivoting gear 10 in the first end position during a jump. Structure and position largely correspond to the representation according to Fig. 7 , In that regard, reference is also made to the preceding description.

If the slider 36 is in the first end position and a further rotation of the pivot pin 23 takes place in the direction of this first end position, the spindle thread 35 continues to rotate about its longitudinal axis with a sufficient force. In order to avoid damaging the pivoting gear 10, in this case the slider 36 is pressed out of the spindle thread 35 and in the direction of the upper side 12 by the spindle thread 35 and due to the abutment of the slider 36 on the inside of the end face 16. Here, the nose 38 abuts on an inner side of a first end 82 of the pivot cover 28, whereby the pivot cover 28 is pivoted about the web 76. As a result, the first end 82 is pressed a piece in the direction of the top 12 and / or the strand element 29, wherein according to this embodiment, the first end 82 does not protrude beyond the top 12 out. At the same time, a second end 83 remote from the first end 82 is pivoted a little way around the web 76 and into the swivel gear 10.

Upon further rotation of the pivot pin 23 and the spindle thread 35, the thread of the slider 36 engages again in the spindle thread 35, whereby a pitch of the spindle thread 35 is skipped. The pivot cover 28 is also pivoted back to its original position.

The slider 36 is in accordance with Fig. 9 shown second end position and there is a further rotation of the pivot pin 23 in the direction of the second end position, rotates at a sufficient force, the spindle thread 35 further about its longitudinal axis. To avoid damaging the pivoting gear 10, the slider 36 is pressed out of the spindle thread 35 and in the direction of the upper side 12 by the spindle thread 35 and due to the abutment of the slider 36 on the inside of the end face 17. Here, the nose 38 abuts on an inner side of a second end 83 of the pivot cover 28, whereby the pivot cover 28 is pivoted about the web 76. As a result, the second end 83 is pressed a piece in the direction of the top 12 and / or the strand element 29, wherein according to this embodiment, the second end 83 does not protrude beyond the top 12 addition. At the same time, the first end 82 facing away from the second end 83 is pivoted a little way around the web 76 and into the swivel gear 10.

Upon further rotation of the pivot pin 23 and the spindle thread 35, the thread of the slider 36 engages again in the spindle thread 35, whereby a pitch of the spindle thread 35 is skipped. The pivot cover 28 is also pivoted back to its original position.

Preferably, a jump of a pitch of the spindle thread 35 by the slider 36, if, for example, after the successful initial assembly of the slider 36 and one or more slats have not reached their intended end position, in particular for producing a closed curtain. In this situation, the pivot shaft connected to the pivot gear 10 and the carriage of the blades is not blocked by the end position of all slats. Due to the skipping of the slider 36 via one or more pitches of the spindle thread 35, the pivot shaft is further rotatable in the direction of the already reached end position, which also can not convert the previously located in the intended end position slats in the final position, so that finally all carriages and / or fins are transferred to the intended end position. In this position, a further skipping of the spindle thread 35 is prevented due to excessive torque for further rotation of the pivot shaft.

Fig. 11a shows a first perspective view of a first strand element 29 according to the invention for a separate profile strand not shown here. The strand member 29 has a single strand 49, which is flexible in this embodiment. Alternatively, the strand 49 may be formed as a rigid rod. Here, the strand 49 has a round cross-section. At regular intervals several members 47 are fixedly attached to the strand 49 or attached to the strand 49.

The links 49 each have a functional side 50 and a clamping side 51 facing away from the functional side 50. Between the functional side 50 and the clamping side 51, the links 49 each have two guide sides 52, 53 facing away from one another and aligned transversely to the plane of the functional side 50 or clamping side 51. The clamping side 51 and the guide sides 52, 53 are each part of a guide device.

The function side 50 of each member 47 has a projection 54. The distance between two immediately adjacent projections 54 of two members 47 determines the width of a respective receiving area 48. In this embodiment, the projection 54 is arranged centrally in the region of the functional side 50. Here, the projection 54 is formed as a web which extends with respect to its longitudinal orientation on the functional side 50 from the first guide side 52 to the second guide side 53 facing away from the first guide side 52. The receiving region 48 and the projections 54 are each part of a coupling device.

Fig. 11b is a second perspective view of the first strand element 29 can be seen. The clamping side 51 of each member 47 has a clamping web 55 which extends in the longitudinal direction of the strand element 29 or the strand 49 with respect to its longitudinal orientation. The clamping web 55 has in this embodiment a first ramp 56, a pedestal 57 and a second ramp 58. The pedestal 57 is located centrally on the clamping side 51 and the first ramp 57 and the second ramp 58 each have one of the ramp 57 to the outside in the direction of the longitudinal axis of the strand element 29 and the strand 49 sloping slope. The ramps 57, 58 facilitate during assembly the insertion of the members 47 of the strand element 29 in the profile groove 46. Due to the two mutually remote and mirror-symmetrical ramps 57, 58 results in this ease of assembly both in a first mounting direction, in each member 47th the first ramp 57 is inserted in front of the second ramp 58 of the same member 47 in the support rail 43 and the profile groove 46, as well as at a first mounting direction rotated by 180 ° second mounting direction, in each member 47, the second ramp 58 in front of the first ramp 57 of the same member 47 in the support rail 43 and the profile groove 46 is inserted.

In a flexible strand 49, the ramps 57, 58 allow tilting of the members 47 when a fixing element 27 and / or a survey 80, 81, in particular with a sloping edge, with a sufficient force abuts a projection 54. In this way, a skipping of the projection 54 is made possible, whereby, for example, damage is avoidable.

In the according to Fig. 6 shown mounted state serve the guide sides 52, 53 for guiding the strand element 29 in the profile groove 46. Here are the Outer surfaces of the guide sides 52, 53 on in each case an inner surface of two mutually opposite inner sides of the profile groove 46.

The width of the functional side 50 is less than the width of the member 47, which results from the distance between the two function sides 52, 53 facing away from each other. This results in the transition region between the functional side 50 and the guide side 52 and the guide side 53 each have a recess or an offset 62. In accordance with Fig. 6 assembled state engages in the offset 62 each have a leg of the profile groove 46 a. Here, the free ends of the two legs of the profile groove 46 facing each other. Due to an interaction of the guide sides 52, 53 and the clamping web 55 with the profile groove 46, the strand element 29 is held by clamping in the profile groove 46 in the embodiment shown here. Additionally or alternatively, a displacement of the strand element 29 can be prevented by means of end caps, not shown here, for the mounting rail 43.

Fig. 11c Each protrusion 54 has a first abutment surface 59 and a second abutment surface 60 facing away from the first abutment surface 59. The abutment surfaces 59, 60 are transversely, in this embodiment, at right angles to the longitudinal orientation of the strand element 29 or of the strand 49 aligned. A first abutment surface 59 of a first member 47 and a second abutment surface 60 of a second member 47 immediately adjacent to the first member 47 define or define the width of the receiving region 48.

In the first end position or the second end position of the slider 36, the abutment surfaces 59, 60 serve as a counter-abutment for the fixing element 27 and the elevation 80, 81. Here Festsetzelement 27 is part of a to the coupling device 48, 54 corresponding formed counterpart device. Thus, a travel of the pivot gear 10 in the first end position or the second end position of the slider 36 by means of the projections 54 and the stop surfaces 59, 60 is limited.

Furthermore, it can be seen that the first ramp 56, the pedestal 57 and the second ramp 58 each have a width of approximately 1/3 of the width of a link 47 in the longitudinal direction of the strand element 29 or of the strand 49.

Fig. 11d is a front view of the first strand element 29 can be seen. In this embodiment, the members 47 have a through hole 61. The strand 49 is inserted through the through holes 61 of the members 47, wherein the members 47 are fixedly mounted on the strand 49. In this embodiment, the members 47 are sprayed onto the strand 49, in particular by means of a plastic processing, spray process. Here, the strand 49 for example, formed as a string. Alternatively or additionally, an adhesive, friction and / or clamping connection between the links 47 and the strand 49 is conceivable. Furthermore, the strand 49 may be integrally formed with the members 47.

Hereinafter, the operation of the invention with reference to the Fig. 1 to 14d explained in more detail:
The strand element 29, 63, 67, 70 can be introduced as a separate component into the profile groove 46 of a profile strand 43. In this way 43 coupling devices 48, 54, 71, 72, 73 are provided in the longitudinal direction of the profile strand, which can cooperate with a correspondingly formed counter devices 27, 80, 81. Here, a clamping side 51 and the guide sides 52, 53 comprehensive guide means for fixedly arranging the strand element 29, 63, 67, 70 and for transmitting by means of the counter device 28, 29 acting on the coupling means 48, 54, 71, 72, 73 forces on the profile strand 43.

Particularly advantageous is the use of such a strand element 29, 63, 67, 70 in connection with a shading system. In a trained example as a horizontally oriented mounting rail profile strand 43 a vertical blind a plurality of carriages and in the region of a carriage designed as a final carriage, a pivoting gear 10 are arranged. On the carriage each a blade is arranged, which extends from the carriage vertically downwards. At the eyelet 24 of the pivot pin 23, a crank rod is arranged, with which the vertical blind can be operated. In the first end position and in the second end position of the pivot pin 23, the slats are positioned such that the curtain formed by the slats is closed or the slats and their slat surface are aligned substantially in the longitudinal direction of the profile strand 43. Furthermore, the eyelet 24 or the crank rod in the first end position and in the second end position is laterally outside the closed Behangbene, whereby the crank rod is easily accessible and an interfering light gap in the area of the crank rod and the edge region of the vertical blind is avoided.

By extending the Festsetzelementes 27 and the survey 80, 81 in one of the two end positions of the pivot pin 23 and the slider 36 enters the Festsetzelemente 27 and the survey 80, 81 in a receiving area 48 of the strand element 29, 63, 67, 70th In an attempt to move the pivot gear 10 by means of the crank rod in the longitudinal direction of the support rail 43, proposes the fixing element 27 and the survey 80, 81 to the stop surface 59 or 60 of a Projection 54, 71, 72, 73, whereby a displacement movement in the first end position and the second end position is prevented. In this case, it may be possible to skip the projections 54 in a first direction of displacement of the swivel gear 10, in particular for closing the curtain and / or a building opening. A displacement of the pivoting gear 10 in the second direction of displacement for opening the curtain and / or the building opening in the first and second end position is prevented.

As a result, the risk of incorrect operation and / or damage to the vertical blind is considerably reduced. Only in an intermediate position between the two end positions, in which the fixing element 27 or the elevation 80, 81 does not protrude into the receiving area 48, a displacement of the pivot gear 10 along the profile strand 43 is possible. In such an intermediate position, however, the slats are rotated due to the coupling on the pivot shaft from the closed Behangbene and transversely to the longitudinal direction of the support rail. As a result, for example, a hooking of the slats of the vertical blind during a displacement of the pivoting gear 10 and a pushing together or pulling apart of the carriage along the profile strand 43 for opening or closing the vertical blinds largely prevented. <B><u> REFERENCE LIST: </ u></b> 10 displacement element 49 strand 11 supporting structure 50 function page 12 top 51 terminal side 13 bottom 52 guide side 14 page 53 guide side 15 page 54 head Start 16 face 55 clamping web 17 face 56 ramp 18 shifter 57 podium 19 role 58 ramp 20 role 59 stop surface 21 role 60 stop surface 22 roller axis 61 Through Hole 23 pivot pin 62 offset 24 eyelet 63 strand element 25 Pivot shaft channel 64 free end 26 worm 65 ramp 27 Locking element 66 podium 28 hinged cover 67 strand element 29 strand element 68 ramp 30 transmission assembly 69 podium 31 pin receiver 70 strand element 32 joint ball 71 head Start 33 worm gear 72 head Start 34 gearing 73 head Start 35 spindle thread 74 podium 36 pusher 75 channel 37 scenery 76 web 38 nose 77 web 39 nose 78 first fixing page 40 cover 79 second fixing page 41 opening 80 survey 42 opening 81 survey 43 extruded 82 first end 44 profile web 83 Second end 45 bead 46 profile groove 47 element 48 reception area
