A support rail is clamped into the holding elements. The release element comprises an eccentric cam element. A hand lever (32) is attached to the release element. The release element is rotatably supported at a base body (18), and the holding elements are attached to the base body. An outer surface of the release element is eccentrically formed to a pin of the release element. An independent claim is also included for an arrangement comprising a support rail of a shading system and a holder.

Description

The invention relates to a holder for a mounting rail of a shading system, such as a vertical blinds, a horizontal blinds, a plissees, or (Raff-) blinds with opposing holding elements, wherein the support rail in the holding elements einklippbar and at least one of the holding elements is associated with a release element , Furthermore, the invention relates to an arrangement of a mounting rail of a shading system and at least one such holder.

Holders for mounting rails and an arrangement of mounting rails with holder are made, for example EP 0 033 856 A1 . GB 2 387 407 A . JP 2006 177034 A . DE 10 2005 052 600 A1 or JP 2003 232 177 A known.

Shading systems, such as the vertical blinds, horizontal blinds, pleats, roller blinds or Roman blinds, which are the subject of particular mention here, have a curtain which can be opened and closed by a support rail. In the support rail also organs for actuating the curtain are often arranged. The mounting rail itself is usually fastened by holders to a building element such as the ceiling or in the window reveal.

In part, the holders are also attached by means of angle elements on a building wall. For this purpose, the holder is first attached to the respective building element, namely usually screwed. Depending on the size (length) and weight of the shading system, a suitable number of holders for holding the shading system is provided. As soon as all holders are attached to the corresponding building element, the mounting rail can be attached to the holders, if necessary already with the curtain attached thereto.

In the from the EP 0 033 856 A1 , of the GB 2 387 407 A or the JP 2006 177034 A known holders are the holding elements manually by turning the release element similar to a bayonet lock openable and closable. Such holders are used in practice especially for horizontal blinds. To attach the mounting rail, the holding element is opened and then introduced the mounting rail with the holding element open. Then, the holding element is closed by turning the release element. During this time, the support rail must continue to be held by a person, which is particularly cumbersome and fatiguing, especially with appropriate Behanggröße due heavy support rails.

The holder according to the DE 10 2005 052 600 A1 belongs to the group of mounting clips. In such mounting clips, the mounting rail can be clipped in a simple manner. It is thus held securely by the mounting clip without having to manually close a retaining element. For example, for renovation work, but also for repair or maintenance of the shading system itself, the shading system can be solved by elastic bending of the mounting clip again from the Befestigungsklipps. This to facilitate is already the subject of the aforementioned DE 10 2005 052 600 A1 , The fastening clip proposed therein has a bead, which makes the fastening clip more elastic and thus facilitates a levering of the fastening clip for removing the shading system. However, the removal of the mounting rail still requires a considerable effort with a separate tool. As a result, there is also the risk of damage, such as scratches, on the mounting rail.

From the US 7 637 302 B2 a holder for a mounting rail of a shading system is known in which the mounting rail is provisionally held after insertion into the holder. The support rail is not yet secured in this position against unintentional release of the holder, so that the support rail can still slide from the holder. Only by manually moving a lever by the operator, the support rail is finally secured.

The JP 2003 232 177 A describes a holder with resiliently on the support rail for holding the same prestressed holding elements, which is used to release the support rail be pushed back by means of a release element. The known holder has a complex structure with resiliently biased holding elements. In case of wear or spring break a secure hold of the mounting rail on the holder is not guaranteed.

The invention is based on the problem to combine the advantages of a mounting clip with those of a holder with openable and closable holding element without taking over the respective disadvantages.

To solve this problem, the holder according to the invention is characterized in that the support rail for releasing the holding elements by means of the release element is expandable. As a result, in the arrangement according to the invention, the support rail associated holding element out of engagement with the associated holding element of the holder can be brought.

According to the invention, the holder, so to speak, has its own tool in order to be able to disengage the carrier rail from the holder and thus be able to remove the carrier rail without requiring a separate tool for this purpose. The removal of the mounting rail of the holders is thus considerably easier. At the same time results in a simple reliable construction.

As a release element is preferably an eccentric element. The advantage of an eccentric element is that it pushes the complementary, the support rail associated holding element from the holding element of the holder and thus brings the two holding elements out of engagement with each other by simply rotating the release element. It does not have to be an eccentric element in the strict sense. It is only important that the radius of the element is greater over the range of the rotational movement.

Furthermore, the release element can be provided with a hand lever. In this case, the operator can take the release element directly on the hand lever and even needs to operate the release element no separate tool.

According to a concrete, constructive embodiment, the release element is rotatably mounted on a base body, which are associated with the holding elements of the holder. In this case, a lateral surface of the release element is formed eccentrically to the axis of rotation of the release element. This results in a particularly simple structural design of the holder. It is particularly advantageous if the base body and the release element have complementary means for provisionally securing the release element to the base body against loss. Depending on the configuration of the holder, it may in fact be the case that the release element is finally secured against loosening on the base body by screwing the holder on, for example, the ceiling or the like. By the complementary securing means is already given before screwing the holder on, for example, the ceiling an effective protection against loss.

According to a structural embodiment of the invention, the lateral surface tapers frustoconically towards the base body, ie in the mounted under a ceiling holder down. As a result, the complementary retaining element on the mounting rail is not only disengaged from the retaining element of the holder, but also pressed slightly downwards (away from the ceiling). The dismantling of the mounting rail is further facilitated. In order to form a good contact surface for the complementary retaining element of the support rail, the lateral surface may be provided with a flattening, which is inclined corresponding to the axis of rotation of the release element.

Furthermore, the lateral surface may be associated with a collar. This forms a stop when clipping the complementary retaining element of the mounting rail. Additionally or alternatively, the main body of the holder may be provided with one or more webs as stops for the complementary retaining element. Covenant and / or the web or webs together with the retaining element of the holder form a slot for receiving the complementary retaining element of the mounting rail.

Fig. 1 shows a shading system, specifically a horizontal blind 10. The horizontal blind has a curtain 11 which is mounted on a mounting rail 12. The support rail 12 also has organs for actuating the curtain, specifically means for opening and closing the curtain 11, namely a pull cord 13, and a device for pivoting blades 14 of the blind, namely a crank rod 15, on. The support rail is an elongated element of any contour, which on one side has an elongated, slot-like opening 16. In the present case, the support rail is concretely a profile, as shown in the international design patent DM / 072482 as sample 1.

In the opening 16 engage a holder 17, by means of which the support rail to a building element, such as the ceiling or the window reveal, can be fastened. Number and distance of the holder 17 with each other depend on the size of the shading system, in this case the horizontal blind 10, and their associated weight from. Number and distance are chosen so that the respective shading system is held securely by the holder 17.

The holder 17 itself is in the FIGS. 2 to 4 shown closer. The holder 17 has a base body 18 and a release element 19 attached thereto. In the FIGS. 2 to 4 is the top of the holder 17 to see, so the side with which the holder is screwed to a building element, such as the ceiling or Fensterbelibung. The main body 18 on the one hand and the release element 19 on the other hand are each formed as one-piece plastic moldings.

The main body 18 has on a longitudinal side 20 each edge near the front end a projecting web 21. These webs 21 are integrally formed in each case near the upper side on the longitudinal side 20 of the base body 18. Alternatively, of course, more than two webs 21 or a continuous web 21 may be provided. Near the underside of the base body 18, a projection 22 is provided along the longitudinal side 20, which continues drop-like downwards and thus forms a ramp 23. The projection 22 is in the vertical direction, so seen perpendicular to the plane of the top spaced from the webs 21, that between the projection 22 and the webs 21, a slot 24 is formed.

On the opposite longitudinal side 25, a further projection 26 is provided. The projection 22 forms on one longitudinal side 20 a first holding element and the projection 26 on the other longitudinal side 25 a second, the first holding element opposite holding element. In these holding elements engage with clipped support rail 12 through the opening 16 formed and these limiting edges 27, 28 of the support rail 12 a. The edges 27, 28 thus form complementary retaining elements.

At the top of the main body 18, a circular cylindrical pin 29 is further formed. This has a slot 30, which serves for screwing the holder 17 to, for example, the ceiling. However, this elongated hole 30 does not necessarily have to be arranged in the pin 29. Rather, means for attaching the holder 17 may be provided on, for example, the ceiling in other suitable manner. In the present case, the slot 30 is arranged in the pin 29, because it is arranged centrally on the upper side of the base body 18.

The release element 19 is rotatably mounted on the pin 29. For this purpose, the release element has a bore 31 complementary to the lateral surface of the pin 29. Furthermore, the release element 19 has a hand lever 32, by means of which an operator can rotate the release element 19 about the pin 29.

The release element 19 is inserted only by means of the bore 31 on the pin 29 and initially not further secured against slipping, as long as the holder 17 is not yet screwed to the building element. In order nevertheless to secure the release element 19 sufficiently provisionally, an ear 33 is integrally formed on the base body. The release element 19 has a complementary pocket 34, the bottom 35 of the ear 33 engages behind. When mounting the release element 19, this example, in the in FIG. 3 shown position initially placed on the pin 29 and then in the in Fig. 2 or 4 shown pivoted position in which the ear 33 covers the bottom 35. In this position, the release element 19 can no longer slip off the pin 29.

The release element 19 is provided around the pin 29 with an eccentric to the pin 29 and thus to the bore 31 circumferential surface 36. The eccentric lateral surface 36 is designed so that it in the in Fig. 2 or 4 shown closed position does not reach into the region of the slot 24. Is the release element in the in Fig. 3 pivoted release position shown, the lateral surface 36 passes due to their eccentric configuration in the region of the slot 24 and thus pushes the edge 27 of the support rail 12 out of the slot 24. The opening 16 of the support rail 12 is slightly widened. This is in the FIGS. 7 and 8 shown in more detail.

At the top, as at the building element, such as the ceiling facing side, the release element 19 is provided with a collar 37 which protrudes slightly over the lateral surface 36. This is in Fig. 4 shown, in which the lateral surface 36 is drawn by dashed lines as a hidden edge. The collar 37 is in the closed position about the same extent on the outer surface 36, as the webs 21. If the holder 17 by means of a wall bracket fastened to a room wall, such wall angles are usually narrower than the holder 17 is long. Often they are even narrower than the distance between the two webs 21. The collar 37 or the above-mentioned continuous web can be supported when clipping the mounting rail to the wall bracket and prevent so that the outer webs 21 break away.

The lateral surface 36 is frustoconical, wherein it tapers downwards, ie away from the collar 37 inwards (to the pin 29). The lateral surface 36 is concretely provided with a flattening 38 which is aligned approximately with the ramp 23 on the projection 22 when the release element 19 in the in Fig. 3 or 7 shown release position is pivoted. In this way, the release element 19 presses in this position, the edge 27 of the support rail 12 not only out of the slot 24, but also slightly downwards, as in Fig. 7 and 8, respectively.

The mounting of the support rail 12 takes place at fully eingeschwenktem, so closed release element 19, in which the release element 19 in the in Fig. 2 or 4 shown position. The operator first hooks the edge 28 behind the projection 26, as in FIG Fig. 5 is shown, and now rotates the support rail 12 upwards counterclockwise, with the edge 27 on the ramp 23 slides up until it snaps behind the projection 22. The mounting rail 12 is now fully assembled.

Fig. 6 shows the fully assembled support rail 12. Both edges 27 and 28 engage behind the respectively associated projection 22 and 28, the operator pivots the release element by means of the hand lever 32 by about 90 ° in the in Fig. 3 or 7 shown position, presses the eccentrically formed lateral surface 36 due to the increasing radius, the edge 27 out of the slot 24 and slightly down. The operator can now pull the support rail 12 downwards, whereby they in the illustration according to Fig. 5 to 7 slightly twisted clockwise. The edge 27 slides down the ramp 23 until it comes free behind the edge 23. The operator can now solve the opposite edge 28 from the projection 26 and so remove the support rail 12 total.

In the embodiment described above, the support rail 12 engages with the edges 27 and 28, the holder 17 from the outside. By operating the release element 19, as described above, the edges 27 and 28 are pressed apart and thus the opening 16 is widened. Of course, the principle of the invention in a kind of kinematic reversal can also apply analogously to holders that engage around the mounting rail from the outside, such as in the DE 10 2005 052 600 A1 1 shown holder. The release element can continue to be assigned to the holder or be assigned to the mounting rail.
