Description

[0001] The invention relates to a guide insert for a guide rail of a curtain system according to the preamble of claim 1.

[0002] Window curtain systems are known for guiding window coverings. These coverings serve for shading or protection against insects. Such systems typically comprise two rails positioned opposite each other on a window opening. The rails run vertically and are parallel to each other. These systems are usually screwed to a building wall or attached directly to a window frame. Guide inserts are provided in the parallel rails, in which the coverings are guided.

[0003] A guide insert is typically designed to guide a single type of curtain. Accordingly, the guide contour of the insert is adapted to the counter contour of the curtain, for example, a welt. A disadvantage of such a guide insert is that using a different type of curtain is usually difficult. Even if a different type of curtain can be used in the guide insert, the guiding quality suffers due to excessively high or low tolerances in the guide.

[0004] It is therefore an object of the invention to specify a generic guide insert that enables the guiding of different types of coverings while maintaining high guiding quality.

[0005] This problem is solved by a generic guide deployment according to the features of claim 1.

[0006] The guide insert according to the invention for a guide rail of a curtain system comprises an insert base, a guide arranged on the insert base for guiding a curtain, wherein the guide insert comprises a first inner leg and a second inner leg, wherein the first inner leg and the second inner leg form a guide and define a guide slot for guiding the curtain, wherein the guide slot spans a guide plane, and wherein the first inner leg and the second inner leg define a receiving space in which a retaining element of a curtain can be received. The receiving space comprises a longitudinal section adjacent to the insert base and a transverse section adjacent to the guide slot, wherein the width of the longitudinal section measured perpendicular to the guide plane is smaller than the width of the transverse section measured perpendicular to the guide plane.

[0007] The differently shaped sections of the guide's receiving space form various contours for receiving and guiding different types of curtain mounting elements. For example, a relatively flat and wide mounting element can be positioned and guided in the transverse section of the receiving space. This section prevents the mounting element from moving out of the guide slot and from moving further into the receiving space towards the base. This ensures that the curtain is held and guided by its mounting element with minimal tolerance. In the longitudinal section of the receiving space, for example, a mounting element that is narrow perpendicular to the guide plane but long towards the base can be positioned and guided with minimal tolerance. The combination of the longitudinal and transverse sections of the receiving space allows for the precise receiving and guiding of a wide variety of mounting elements with minimal tolerance.

[0008] It is advantageous that the recording chamber is T-shaped. The transverse section of the recording chamber thus connects directly to the longitudinal section of the recording chamber. The transverse and longitudinal sections together form the T-shaped recording chamber.

[0009] It is particularly provided that the first inner leg or the second inner leg is hook-shaped. It is especially advantageous for both the first and second inner legs to be hook-shaped. The hook-shaped design of the receiving space creates two distinct sections: the transverse section and the longitudinal section. In an alternative embodiment, the inner legs can also be designed to form a third section or further sections, distinct from the transverse and longitudinal sections, to accommodate and guide additional holding elements. It is particularly advantageous for the first and second inner legs to be arranged symmetrically to each other with respect to the guide plane. Accordingly, the receiving space, particularly the transverse and longitudinal sections, is also symmetrically designed with respect to the guide plane.

[0010] It is specifically provided that the first inner leg or the second inner leg has a first stop surface oriented transversely to the guide plane, wherein the first stop surface is to be assigned to the transverse section of the receiving space. Preferably, both the first and the second inner leg have a first stop surface oriented transversely to the guide plane, wherein the first stop surface is to be assigned to the transverse section of the receiving space. The first stop surface is formed adjacent to the guide slot. If the curtain is loaded in the direction away from the guide insert, the retaining element is supported against the first stop surface. Supported against the first stop surface, the retaining element does not slip out of the receiving space.

[0011] Preferably, the first inner leg or the second inner leg has a second stop surface oriented transversely to the guide plane, wherein the second stop surface faces the first stop surface and is associated with the transverse section of the receiving space. Preferably, both the first and second inner legs have the second stop surface oriented transversely to the guide plane. The retaining element of the curtain rests against the second stop surface when it is subjected to pressure in the direction of the floor. This keeps the movement tolerances of the retaining element, particularly a flat retaining element, low.

[0012] Preferably, the first stop surface or the second stop surface of the first inner leg is oriented approximately perpendicular to the guide plane. Preferably, the first stop surface and the second stop surface of the first inner leg are oriented approximately perpendicular to the guide plane. Preferably, the first stop surface or the second stop surface of the second inner leg is oriented approximately perpendicular to the guide plane. Preferably, the first stop surface and the second stop surface of the second inner leg are oriented approximately perpendicular to the guide plane.

[0013] It is advantageously provided that the first inner leg has a third stop surface oriented approximately parallel to the guide plane, with the third stop surface being associated with the longitudinal section. Preferably, the second inner leg has a fourth stop surface oriented approximately parallel to the guide plane, with the fourth stop surface being associated with the longitudinal section. Particularly preferred are the third stop surface of the first inner leg and the fourth stop surface of the fourth inner leg arranged opposite each other with respect to the guide plane. The retaining element of the curtain can be guided perpendicular to the guide plane between the third stop surface and the fourth stop surface.

[0014] It is specifically provided that the first inner leg and the second inner leg each extend from a first end adjacent to the base of the insert to a free second end, the guide slot being bounded by the free second ends of the first inner leg and the second inner leg, respectively. The guide slot preferably has a width, measured perpendicular to the guide plane, that is smaller than the width of the transverse section, particularly smaller than the width of the longitudinal section, preferably less than 2.5 mm, particularly less than 1.5 mm, and advantageously less than 1.0 mm. The narrower the guide slot, the narrower the retaining element for the curtain can be without it slipping out of the receiving space via the guide slot. The narrower the retaining element, the smaller the diameter of the wound-up curtain.

[0015] It is advantageously provided that the guide insert comprises a first outer leg and a second outer leg for positioning the guide insert in a base rail of a blind system. The first outer leg or the second outer leg is preferably elastic, in particular made of an elastomer. The outer legs position the guide insert in the base rail. If the outer legs are elastic, the guide insert can be easily levered into the base rail. When the guide insert is inserted through an opening in the base rail, the outer legs can deform, thus allowing the guide insert to be inserted through the opening.If the guide insert is located inside the base rail, the outer legs can spread apart again and position the guide insert inside the base rail, supported by the legs of the base rail.

[0016] The guide insert is particularly advantageous when designed as a single piece. This allows for efficient manufacturing of the guide insert. The base of the insert and the guide mechanism are preferably made of a rigid plastic. The guide insert itself is preferably made of two plastic components.

[0017] Further features of the invention will become apparent from the description and the drawing, in which an embodiment of the invention, described in detail below, is illustrated. The drawing shows: Fig. 1 a schematic, perspective representation of the curtain system according to the invention, Fig. 2 a schematic sectional view of the guide rail according to the invention, Fig. 3 a schematic cross-sectional view of the command deployment, Fig. 4 a schematic sectional view of the guide unit with guided curtain and Fig. 5 a schematic sectional view of the guide insert with a further version of a guided curtain.

[0018] In Fig. Figure 1 shows a curtain system 1. The curtain system 1 comprises a curtain 2, a curtain box 3 and two lateral guide rails 4, 4'.

The window 31 is in Fig. 1 is represented only by roughly dashed lines. The curtain system 1 can also be arranged on the inside of the building in front of window 31.

[0019] The curtain box 3 is arranged horizontally above the window 31 and includes a winding roller (not shown) for winding and unwinding the curtain 2. A first guide rail 4 and a second guide rail 4' are arranged laterally on the window 31. The guide rails 4 and 4' are located below the curtain box 3. They are vertically oriented and parallel to each other, spaced approximately the width of the window. The guide rails 4 and 4' are attached to the outer facade 30, preferably by screws. Alternatively, they can also be attached to the window frame. The curtain system 1 can be adapted to various window types or openings to be covered.

[0020] In the exemplary embodiment, the curtain 2 is designed as a fabric for shading and / or protection against insects. For shading, the curtain 2 can be lowered from the winding roller and is guided laterally by the first guide rail 4 and the second guide rail 4'. When the curtain 2 is raised, it is wound back onto the winding roller in the curtain box 3. In an alternative embodiment of the curtain system 1, other curtains 2, such as external venetian blinds, roller shutter slats, insect screens, etc., can of course be provided.

[0021] In Fig. Figure 2 shows a cross-section of the guide rail 4. The guide rail 4 comprises a base rail 5 and a guide insert 15 arranged in the base rail 5. The guide insert 15 serves to guide the blind 2 precisely. The base rail 5 is intended to be fixed to the masonry of a building or to a window frame, for example by screws. The guide insert 15 is detachably clipped into the base rail 5. This allows the guide insert 15 to be easily installed and removed from the base rail 5 after it has been attached. Alternatively, the guide insert 15 can also be threaded into the base rail 5 lengthwise.

[0022] As in Fig. As shown in Figure 2, the base rail 5 is formed from a first side wall 6, a second side wall 6', and a base 7 connecting the side walls 6 and 6'.

The side walls 6 and 6' have a height measured perpendicular to the base 7, with the height of the side walls 6 and 6' being approximately the same. In an alternative embodiment of the base rail 5, it may be advantageous to provide side walls 6 and 6' of different heights. The side walls 6 and 6' each have an end 8 and 8' facing away from the base 7. At each end 8 and 8' of the side walls 6 and 6', a closing leg 9 and 9' is arranged. The closing legs 9 and 9' are L-shaped. The end legs 9, 9' are each inclined towards the other side wall 9, 9'. The end leg 9 of the first side wall 7 is oriented perpendicular to it.The end leg 9' of the second side wall 7' is aligned perpendicular to it. The end legs 9, 9' define an opening 10. The opening 10 of the base rail 5 extends along the entire longitudinal direction of the base rail 5 in the viewing direction. Fig. 2 and thus forms an insertion slot for the guide insert.

[0023] As in Fig. As shown in Figure 2, an intermediate shelf 11 is formed between the end legs 9, 9' and the base 7, extending from the first side wall 6 to the second side wall 6'. The intermediate shelf 11, the side walls 6, 6' and the end legs 9, 9' define an interior space 12 of the base rail 5, in which the guide insert 15 is arranged.

[0024] In the present embodiment, the base rail 5 is made of aluminum. In an alternative embodiment, another material may also be suitable.

[0025] In the exemplary embodiment, the base rail 5 is formed in one piece. A multi-part design of the base rail 5 may also be advantageous.

[0026] As in Fig. As shown in Figure 2, the guide insert 15 is arranged in the interior 12 of the base rail 5. Fig. Figure 3 shows the guide insert 15 in an enlarged view. The guide insert 15 comprises a base 16, two outer legs 17, 17' and two inner legs 19, 19'.

[0027] As in Fig. As shown in Figure 3, the guide insert 15 comprises a guide 18 for guiding the curtain 2. The guide 18 is arranged on the base 16, specifically on a first side 34 of the base 16. The base 16 has a first side 34 facing the interior 12 of the base rail 5. Furthermore, the base 16 has a second side 35 facing away from the interior 12 of the base rail 5. The first side 34 and the second side 35 of the base 16 are aligned parallel to each other. The guide 18 includes a receiving space 20 for receiving a retaining element 13 of the curtain 2. The guide 18 includes a guide slot 23 through which the curtain 2 projects outwards from the receiving space 20 into the vicinity of the guide insert 15. The guide slot 23 defines a guide plane 24. The guide level 24 is preferably designed perpendicular to the operating floor 16.The guide slot 23 extends along the entire length of the guide insert 15, with the length being measured in the longitudinal direction of the guide insert 15.

The transverse section 22 has a height h2 corresponding to the distance between the second stop surface 27, 27' and the first stop surface 26, 26'. The height h2 of the transverse section 22 of the receiving space 20 corresponds to at most 70%, in particular at most 60%, preferably at most 50%, and in particular at most 40% of the height h1 of the longitudinal section 21 of the receiving space 20. The height h2 of the transverse section 22 of the receiving space 20 corresponds to at least 15%, in particular at least 25%, of the height h1 of the longitudinal section 21 of the receiving space 20.

[0037] As in Fig. As shown in Figure 3, the first outer leg 17 and the second outer leg 17' are arranged on the base 16 of the guide insert 15. The first outer leg 17 and the second outer leg 17' are arranged on the first side 34 of the base 16. The first outer leg 17 and the second outer leg 17' are spaced apart from each other. The guide 18 is arranged between the first outer leg 17 and the second outer leg 17'. The first inner leg 19 and the second inner leg 19' are arranged between the first outer leg 17 and the second outer leg 17'. The two outer legs 17, 17' are arranged obliquely to the guide plane 24. One end of an outer leg 17, 17' is arranged on the base 16, in particular on the first side 32 of the base 16. Furthermore, the two outer legs 17, 17' each include a free end.The outer legs 17, 17' are designed and arranged such that they diverge towards their free ends.

[0038] As in Fig. As shown in Figure 3, the two outer legs 17, 17' are preferably made of an elastic material, in particular an elastomer. The guide 18, in particular the inner legs 19, 19', and the insert base 16 are preferably rigid, in particular made of a thermoplastic, thermoset, fiber-reinforced composite, or similar plastic. An aluminum construction may also be advantageous. The guide insert 15 is preferably formed in one piece. Due to the elastic design of the outer legs 17, 17', they can yield elastically during the assembly or disassembly of the guide insert 15 in the base rail 5. Once the guide insert 15 is in the base rail 5, the outer legs 17, 17' can spread apart again and position the guide insert 15 in the base rail 5.

The retaining element 13 is rather compact and rests against the first stop surface 26, 26'. The retaining element 13 extends from the first stop surface 26, 26' into the longitudinal section 21 of the receiving space 20. If the retaining element 13 sits slightly deeper in the longitudinal section 21 than shown, the third stop surface 28 of the first inner leg 19 and the fourth stop surface 29 of the second inner leg 19' form a guide perpendicular to the guide plane 24. The retaining element 13 is designed to be large enough to extend into the longitudinal section 21 and thus does not contact the second stop surface 27, 27'.

[0041] In Fig. In section 5, the retaining element 13 is designed as a continuous contour. The contour is T-shaped. The contour is relatively flat, so that when it rests against the first stop surface 26, 26', it does not extend into the longitudinal section 21. The retaining element 13 is located only in the area of ​​the guide slot 23 and in the transverse section 22 of the receiving space 20. The retaining element 13 is wide enough that, when the curtain 2 is pushed towards the base 16, it comes into contact with the second stop surface 27, 27'. Thus, the retaining element 13 is guided completely within the transverse section 22 of the receiving space 20 between the first stop surface 26, 26' and the second stop surface 27, 27'.

[0042] As in Fig.As shown in Figure 2, the guide insert 15 is arranged in the base rail 5 such that the guide 18, in particular the guide slot 23 of the guide 18, is aligned with the opening 10 of the base rail 5, so that the curtain 2 can project out of the guide rail 3 from the receiving space 20 of the guide insert 15 via the guide slot 23 and the opening 10 of the base rail 5.
