Description

The invention relates to a bundling element for bundling at least two operating cords for a shading system with a clamping device for setting the operating cords in a clamping position at a train in the longitudinal direction of the operating cords and for releasing the operating cords in a release position in a spreading apart of the operating cords away from each other, wherein the clamping device having at least one pivot axis pivotable Festsetzelemente cooperating for setting the operating cords in the clamping position, a fixing plane is aligned perpendicular to the longitudinal direction of the actuating cords and a center of the pivot axis intersects, wherein the Festsetzelemente in the clamping position out of the fixing level and in one of the train are pivoted in the longitudinal direction of the actuating cords in the opposite direction, and a first fixing element of a first pivoting flap and a z wide fixing element is associated with a second pivoting flap.

Such a bundling element is from the US 2011/0174449 A1 known.

From the GB 2481814 A a bundling element is known in which a housing with fixing elements consists of two housing halves which are detachably connected to each other. The bundling element is to release the bundled operating cords, for example, if a child gets caught with his limbs or the head in the operating cords. A disadvantage here is that the fastening or insertion of the operating cords, in particular for the end user, for example after a release of the operating cords, is complicated and unwieldy. In addition, the ends of the operating cords are provided with a node for a sufficient support to prevent accidental release of the operating cords of the bundling element, which, however, there is a risk that the operating cords are not delayed or only in the event of spreading the operating cords of the Clamping device are released.

It is therefore the object underlying the invention to develop a bundling element of the type mentioned in such a way that the operability or assembly of the operating cords is improved and both reliable release of the operating cords at a spreading apart of the operating cords and a reliable clamping the operating cords at a Transferring a tensile force in the longitudinal direction of the operating cords is improved.

The object underlying the invention is achieved by a bundling element of the type mentioned, wherein a support structure and / or a housing for receiving the free ends of the operating cords the two pivotally mounted on the support structure and / or the housing pivoting flaps for setting and releasing the operating cords , wherein the pivoting flaps allow opening and closing of the support structure and / or the housing for introducing the free ends of the operating cords in the inside or to lead out of the interior of the support structure and / or the housing and the pivoting flaps at the same time for attaching and releasing the Serve operating cords.

It is advantageous that due to the arrangement of the clamped together for clamping the operating cords Festsetzelemente in the clamping position outside the mounting plane and in a direction away from the train and the fixed level upstream position, with a tensile force on the bundling element on the operating cords and in whose longitudinal alignment for actuating a shading system, the clamping action of the clamping device is reinforced, whereby unintentional release of the operating cords is prevented in a conventional operation or operation, for example, a shading system. In particular, the fixing elements are in the clamping position below the fixing level for fixing the operating cords arranged. Preferably, the train is directed in the longitudinal direction of the operating cords away from the clamping device. Preferably, in a transmission and / or forwarding of a tensile force in the pulling direction by means of the operating cords, a shading system can be operated.

According to a further development, the fixing elements are pivoted in the release position out of the fixing plane and in the direction of the train in the longitudinal direction of the actuating cords. In particular, the fixing elements are arranged in the release position above the fixing level for releasing the operating cords. Preferably, the pivoting movement of the fixing elements for changing from the clamping position to the release position and from the release position to the clamping position is guided by the fixing level. In particular acts on the fixing elements in the clamping position directed in the direction of the release position train and / or a force. Due to the clamping action between the Festsetzelementen and the operating cords in the clamping position acts on the fixing a train of the opposite force component, whereby acts on the fixing a force for pivoting the fixing elements in the direction of the fixed plane and / or the train. Preferably, the strongest clamping effect of Festsetzelemente for setting the operating cords in the fixing level is reached. Thus, the clamping effect in a conventional operation or actuation of a shading system and when transmitting a tensile force on the bundling element on the operating cords is additionally reinforced. In particular, the fixing elements are in an orientation in the fixing level most strongly engaged with each other or engage in the deepest one another.

According to a further embodiment, a first fixing element and a second fixing element are each pivotable about a separate pivot axis and the pivot axes of the two fixing elements are arranged in the same fixing plane. The pivotal movement of the two fixing elements can be coupled together. Preferably, the first fixing element and the second fixing element facing each other and / or spaced from the pivot axis. This ensures that the distance between the two Festsetzelemente is at an orientation in the fixed plane least, so that the greatest clamping effect can be achieved. In particular, the first fixing element has a web and the second fixing element has a groove for at least partially receiving the web for clamping the operating cords between the web and the groove. As a result, a simple and effective clamping of the actuating cords can be produced, in which the actuating cord is deflected several times within the clamping. Preferably, thereby attaching a node at the free end of the operating cords is dispensable.

Preferably, a first fixing element of a first pivoting flap and / or a second fixing element is associated with a second pivoting flap. Preferably, the Schenkklappen are each pivotable about a pivot axis. In particular, the pivoting flap is integrally formed with the respective fixing element.

According to a development, a support structure and / or a housing for receiving the free ends of the operating cords on the two pivotally mounted on the support structure and / or the housing pivoting flaps for setting and releasing the operating cords. By means of two swivel flaps pivotally mounted on a housing, a partially hinged and closable housing can be realized, whereby advantageous constructions can be achieved for operability and / or reliability. In particular, the support structure and / or the housing consists of at least one rigid support structure part and / or a rigid housing part and two pivoting flaps pivotally mounted on the rigid part.

Preferably, the housing for the pivoting flaps has in each case a pivot axis which is aligned transversely, in particular at right angles, to the pulling direction for actuating the shading system and / or for longitudinal alignment of the actuating cords and / or is arranged in a central region of the housing. Thus, the pivoting flaps open and / or close only with a force acting transversely, in particular at right angles, to the usual pulling direction for actuating the operating cords on the pivoting flaps. As a result, high tensile forces, in particular in the longitudinal direction of the operating cords, can be transmitted to operate the shading system, while considerably lower forces can be sufficient to release the actuating cords or the pivoting of the pivoting flaps to the usual operation.

According to a further embodiment, the pivot flaps and / or the pivot axes between a front part and a rear part of the support structure and / or the housing are arranged. In particular, the front part and the rear part are firmly connected to each other. Preferably, the pivot axis is rotatably connected to the rear part, wherein a free end of the pivot axis is rotatably mounted in a receptacle of the front part. As a result, the pivot axis is stably supported and / or the risk of bending or damage to the pivot axis is reduced.

The two pivoting flaps can cooperate to provide a clamping device for fixing the actuating cords, in particular in a middle region of the supporting structure and / or of the housing. Thus, the pivoting flaps fulfill a dual function. On the one hand, the pivoting flaps allow the supporting structure and / or the housing to be opened and closed, to introduce the free ends of the operating cords in the interior of the support structure and / or the housing or to lead out of the interior of the support structure and / or the housing. On the other hand, the pivoting flaps also serve to fasten and release the operating cords. Preferably, the clamping device is designed for clamping the operating cords between a first fixing element of a first pivoting flap and a second fixing element of a second pivoting flap. The production or the resolution of the clamping thus takes place when closing or opening the pivoting flaps.

In particular, the pivoting flaps each have an opening and / or a slot at an upper end. Through the opening and / or the slot in the assembled state, the operating cords are guided through and into the interior of the support structure and / or of the housing. In the closed state of the housing and / or the supporting structure, the pivoting flaps abut one another such that the two openings or slots of the two pivoting flaps form a common opening and / or a common slot, through which or through which the actuating cords are guided. Preferably, the common opening and / or the common slot of the two Schenkklappen is expandable by pivoting the two pivoting flaps to a larger compared to the common opening and / or the common slot mounting opening. As a result, the insertion or introduction of the operating cords in the interior of the support structure and / or the housing and the clamping is greatly facilitated.

Preferably, the first fixing element and the second fixing element are each turned from the bearing for pivoting the pivoting flaps, in particular the pivot axis, into the supporting structure and / or the housing. In particular, the first fixing element and the second fixing element are facing each other. Preferably, the first fixing element and the second fixing element are each arranged eccentrically to the associated pivot axis.

According to a development, the pivoting flaps are mounted in opposite directions to each other pivotally. In particular, the pivoting direction for opening the support structure and / or the housing is directed to the left in the first pivoting flap and to the right in the case of the second pivoting flap. Preferably, the pivoting direction for closing the support structure and / or the housing in the first pivoting flap to the right and the second pivoting flap is directed to the left. The pivoting flaps may each have a coupling element for coupled and / or simultaneous pivoting about the bearings and / or pivoting axes for pivoting the pivoting flaps. As a result, a simultaneous opposing pivoting of the pivoting flaps can be realized, whereby the operability and / or function of the bundling element is improved. Preferably, the coupling element of the first pivoting flap acts with the Coupling element of the second Schenkklappe together. The coupling element may be formed as a, in particular in the support structure and / or the housing directed into, gear or a gear segment. Here engages the gear or gear segment of the coupling element of the first pivoting flap in the gear or gear segment of the coupling element of the second pivoting flap.

According to a further embodiment, the two pivoting flaps each have a flap area for closing and opening the support structure and / or the housing, which in the closed state of the support structure and / or the housing starting from the bearing for pivoting the pivoting flaps upwards and in the open state Support structure and / or the housing of the support structure and the housing away to the outside. Preferably, the flap portion has at its upper free end a, in particular in the pivoting direction of the pivoting flaps aligned slot for receiving the operating cords. In particular, the slots of the two pivoting flaps are aligned and arranged such that the two slots form a single common slot in mutually pivoted and adjacent pivoting flaps.

The pivoting flaps may each have a first coupling part which cooperates with a correspondingly formed second coupling part on the support structure and / or on the housing for releasably securing the pivoting flaps to the support structure and / or on the housing in a closed state of the support structure and / or the housing. In particular, the second coupling parts are assigned to the rear part and / or front part of the support structure and / or of the housing, so that the pivoting flaps can be fixed in the closed position or in a position to be pivoted toward one another. Preferably, the connection of the first coupling part with the second coupling part due to a spreading apart of the operating cords across a pulling direction for actuating the shading system is solvable.

According to a development, the first coupling part is designed as a first latching element and the second coupling part as a second latching element corresponding to the first latching element. A corresponding latching connection can be produced in a simple manner and inexpensively. Preferably, the first latching element is associated with an upper end of the flap region and the second latching element is associated with an upper end of the support structure and / or the housing, in particular the rear part and / or the rear side of the housing.

Preferably, the support structure and / or the housing has at a lower end a single operating cord for transmitting a tensile force to the bundling element and for jointly actuating the operating cords. Thus, a plurality of actuating cords are bundled by means of the bundling element such that all operating cords are actuated simultaneously and together with a single operating cord. The bundling element may be formed as a string weighter.

The housing 11 has a rear part 13, a front part 14, a first pivoting flap 15 and a second pivoting flap 16. The rear part 13 is firmly connected to the front part 14. In this embodiment, the front part 14 is attached as a lid on the rear part 13. The rear part 13 has a rear side 17 and a side wall 18 extending from the rear side 17 in the direction of the front part 14. The side wall 18 essentially surrounds or covers the lower half of the housing 11 in this exemplary embodiment.

The front part 14 extends in this embodiment, a little way beyond the upper end of the side wall 18 upwards. Between the back 17 and the front part 14, the pivoting flaps 15, 16 are pivotally mounted on a bearing 19. In this figure, only the bearing 19 of the first pivoting flap 15 can be seen.

From the closed state of the housing 11 shown here, the pivoting flaps 15, 16 about the bearing 19 away from each other and in relation to the housing 11 to the outside. In the closed state of the housing 11, the pivoting flaps 15, 16 abut each other.

The actuating cords 12 are arranged in this embodiment substantially parallel to each other in a resulting due to the longitudinal alignment of the slots 20 level, which is aligned at right angles to the pivot axis of the bearing 19 here.

The pivoting flaps 15, 16 are each releasably coupled with a coupling connection 21 in this embodiment with the housing 11 and the rear part 13. Here, the coupling connection 21 is exemplified as a latching connection, which is arranged at the upper end of the housing 11.

Fig. 2 shows a second perspective side view of the bundling element 10 according to the invention with an open housing 11. In this open state, the pivoting flaps 15, 16 are each about their bearing 19 around and away from each other pivoted outwards. As a result, the in Fig. 1 shown coupling compounds 21 dissolved.

In the Fig. 2 the individual components are provided, which are provided for producing the coupling connection 21. The pivoting flaps 15, 16 each have a first coupling part 22, which in this exemplary embodiment is associated with an upper end of the pivoting flaps 15, 16 facing the rear part 13 or the rear side 17. The rear side 17 or the rear part 13 has at its upper end in each case one to the first coupling part 22 correspondingly formed second coupling part 23. Here, the first coupling part 22 and the second coupling part 23 are formed as mutually correspondingly formed locking elements, which allow a releasable latching connection of the pivoting flaps 15, 16 with the housing 11 and the rear part 13.

In this embodiment, the pivoting flaps 15, 16 each have a front wall element 24, which is arranged in the plane of the front part 14. In the open state of the housing 11, the front wall elements 24 are pivoted together with the pivoting flaps 15, 16 to the outside, whereby the interior of the housing 11 and a clamping device 25 for setting and releasing the operating cords 12 is better visible and accessible. In the opened state of the housing 11 or in the case of pivot flaps 15, 16 folded away from one another, the clamping device 25 releases the actuating cords 12. Thus, the clamping device 25 is in a release position.

The second fixing member 28 has a groove 29, which is designed to receive the web 27. The groove 29 is transversely aligned, in this case at right angles, to the pivoting direction of the second pivoting flap 16 or parallel to the pivoting axis of the bearing 19. In the illustrated here open state of the pivoting flaps 15, 16 and the release position of the clamping device 25, the web 27 and the groove 29 are disengaged and pivoted away from each other away, whereby the operating cords 12 are released.

Each pivoting flap 15, 16 has a coupling element 30, wherein the coupling elements 30 of the pivoting flaps 15, 16 are engaged with each other. In this embodiment, the coupling elements 30 are formed as gear segments. The teeth of the coupling elements 30 of the two pivoting flaps 15, 16 face each other and are at least partially engaged with each other. As a result, the pivoting flaps 15, 16 are coupled to one another such that a common or simultaneous pivoting of the pivoting flaps 15, 16 and the fixing elements 26, 28 is ensured.

Fig. 4 shows a sectional front view of the bundling element 10 according to the invention with a closed housing 11. The bearings 19 each include a pivot axis 31, so that the pivoting flaps 15, 16 are each rotatably mounted about its own pivot axis 31. The pivot axis 31 extends, starting from the rear side 17 of the rear part 13 in the direction of the front part 14 not shown here. Here, the pivot axes 31 are arranged in the central region of the housing 11. Furthermore, the pivot axes 31 are arranged at a distance from each other in the edge region of the housing 11.

In the illustration shown here, the pivoting flaps 15, 16 according to the closed state or the clamping position according to Fig. 4 shown to each other, wherein the pivoting flaps 15, 16, however, are spaced from each other.

In the clamping position, the first fixing element 26 and the second fixing element 28 are aligned starting from the bore 33 toward each other and obliquely inclined downwards. As a result, the web 27 and the groove 29 are below the center 41 of the bore 33 or in the mounted state of the pivot axis 31. The fixing elements 26, 28 or the web 27 and the groove 29 are located in the clamping position below a fixing plane 42nd The fixing plane 42 results in this embodiment, due to a plane intersecting the two centers 42 of the holes 33 and the pivot axes 31. Furthermore, the fixing plane 42 is aligned at right angles to the longitudinal orientation of the operating cords 12 in a transmission of a tensile force by means of the bundling element 10 on the operating cords 12 for operating a shading system. The corresponding longitudinal alignment of the actuating cords 12 with respect to the orientation of the pivoting flaps 15, 16 and the pulling direction of the tensile force in an operation of the shading system with a via the bundling element 10 transmitted tensile force is indicated according to the arrow 43. Thus engages in the use of the bundling element 10 of the web 27 obliquely downwardly inclined into the groove 28 a. The guided between the web 27 and the groove 29 actuating cords 12 are hereby repeatedly deflected and jammed. The fixing elements 26, 28 are pivoted in the clamping position against the direction of the train 44 from the fixing plane 42.

• Mehrere Betätigungsschnüre 12 einer Verschattungsanlage sind mit dem Bündelungselement 10 bündelbar, so dass sämtliche Betätigungsschnüre 12 mittels des Bündelungselementes 10 oder einer an dem Bündelungselement 10 befestigten Bedienschnur gleichzeitig auf einfache Weise betätigen lassen.

The invention will be described below with reference to FIG Fig. 1 to 9 explained in more detail:

• Several operating cords 12 of a shading system can be bundled with the bundling element 10, so that all operating cords 12 can be actuated simultaneously by means of the bundling element 10 or an operating cord attached to the bundling element 10 in a simple manner.

For this purpose, the free ends of the actuating cords 12 are guided through the clamping device 25 and firmly clamped with the clamping device 25. Here, the necessary for operating the shading system tensile forces by means of the bundling element 10 can be reliably transferred to the operating cords 12.

When at least two actuating cords 12 are spread apart, in which the actuating cords 12 are moved away from one another and in a direction transverse to a pulling direction for a conventional actuation of the actuating cords 12 as indicated by arrow 43, for example due to engagement of a body part between the two actuating cords 12 the actuating cords 12 in the slots 20 away from each other. The spread apart operating cords 12 are located at mutually away away ends of the slot 20 of the first pivoting flap 15 and the slot 20 of the second pivoting flap 16 at. Thus, due to the spreading apart of the actuating cords 12, a force directed away from each other and directed in the direction of the pivoting direction about the pivot axes 31 acts on the pivoting flaps 15, 16.

At a sufficient release force, which is well below the usual operating forces for actuating the operating cords 12 and in particular at a maximum tripping weight of 6 kg, the coupling connections 21 of the pivoting flaps 15, 16 are released with the housing 11 and the pivoting flaps 15, 16 pivot together with the fixing elements 26, 28 to the outside. As a result, the clamping device 25 opens at the same time and releases the actuating cords 12. As a result, a violation of a person caught between the actuating cords 12, in particular the strangulation of a child reliably prevented.

For subsequent repair or reassembly it is only necessary to insert the free ends of the actuating cords 12 in the open housing 11 and perform through the open clamping device 25. Subsequently, the pivoting flaps 15, 16 for closing the housing 11 toward each other pivoted. As a result, the actuating cords 12 are clamped firmly at the same time by means of the clamping device 25 in the bundling element 10.

In a transmission of a tensile force on the actuating cords 12 in the longitudinal direction according to arrow 43 for operating a shading system acts on the fixing elements 26, 28 an upward force. Due to the coupling connections 21, however, an undesired swinging up of the pivoting flaps 15, 16 or the fixing elements 26, 28 is prevented. In addition, the fixing elements 26, 28 are pressed in a transmission of a tensile force on the bundling element 10 from its position below the fixing plane 42 upwards in the direction of the fixing plane 42. However, since the fixing elements 26, 28 engage with one another most strongly when aligned in the fixing plane 42 and produce the greatest clamping effect for the actuating cords 12, the clamping effect of the clamping device 25 is thereby increased. As a result, the risk of unintentional release of the operating cords 12 in a conventional operation of a shading system is considerably reduced.
