MODE(S) FOR CARRYING OUT THE INVENTION

[0033] Next the invention is described in more detail with the help of exemplary embodiments. In drawings in different embodiments the same reference numbers are used for the same elements.

[0034] FIGS. 1 to 4 represent only the part of the curtain wire fastening system onto a window frame which is installed onto the left vertical part of the window frame and from which the curtain wire runs towards the right part of the window frameit is obvious to the person skilled in the art that the right vertical frame part comprises exactly the same structure of the fastening system, from which the curtain wire runs towards the left part of the window frame. In other words the curtain wire fastening system to be installed onto the window frame have exactly the same design both on the left and on the right. Therefore in drawings only the part of the curtain wire fastening system is represented which is installed onto the left part of the window frame.

[0035] The curtain wire 1 fastening system onto a window frame 2 comprises at both ends of the curtain wire an elongated mounting bracket 3 to be installed onto the window frame 2, see FIGS. 1 to 4 and 16.

[0036] One end 4 of the mounting bracket 3 is intended to be fastened behind the corresponding outer lateral edge of the window frame 2. At the other end of the mounting bracket 3 a fixing element 5 is formed for fastening the end 6 of the curtain wire 1.

[0037] Around the mounting bracket 3 comprising the fixing element 5, a cover element 7 comprising a cavity is fixed so that the end of the mounting bracket 3 comprising the fixing element 5 and the end 8 of the curtain wire 1 attached to said fixing element 5 is placed inside the cavity of the cover element 7.

[0038] According to the first embodiment, the cavity of the cover element 7 is surrounded by two end walls 8, 9 and with a mainly cylindrical side wall 10, whereby said cylindrical side wall 10 comprises two slots 11, 12, one slot being intended for the end of the mounting bracket 3 comprising fixing element 5 and the other slot is intended for the end 6 of the curtain wire 1, and one end wall 9 is formed by a cap 13 fixed onto the cover element, FIGS. 1, 2, 5 to 15.

[0039] According to the second embodiment the cavity of the cover element 7 is surrounded by one end wall 8 and by the mainly cylindrical side wall 10, where said cylindrical side wall 10 comprises two slots 11, 12, one for the end of the mounting bracket 3 comprising a fixing element 5 and the other for the end 6 of the curtain wire 1, FIGS. 3 to 11.

[0040] In both embodiments the fastening means of said cover element 7 is formed by a groove 14, when said groove is formed inside the cavity of the cover element 7 into one end wall 8 between two slots 11, 12 in the cylindrical side wall 10 for receiving at least the end of the mounting bracket 3 comprising the fixing element 5, FIG. 5 into said groove.

[0041] In the embodiment, where the cap 13 forms the other end wall of the cover element 7, said cap 13 is fixed onto the cover element 7 with the help of a snap-fit 15 or an interference fit, FIGS. 12 to 15.

[0042] The elongated mounting bracket 3 is formed from wire material, one end of which is turned back so that it comprises an end part 4 turned mainly crosswise in respect to the elongated part of the mounting bracket 3 and a tip 18 which is turned at an angle in respect to the end part 4, FIG. 16. At the other end of the elongated mounting bracket 3 a mainly U-shaped fastening element 5 is formed, where arms 17, 18 of said U-shaped part are mainly crosswise in respect to the elongated part of the mounting bracket 3 and the arm 17 of the U-shaped part connected to the elongated part of the mounting bracket 3 comprises a notch 19 for fixing a hook or loop at the end 6 of the curtain wire.

[0043] In the preferred embodiment the mounting bracket 3 is made of metal wire. However the mounting bracket can also be made of metal strip, which is also covered with plastic covering.

[0044] When installing the curtain wire 1 fastening system onto the window frame 2 according to the first embodiment in front of a glass pane or glass package 20, the end wall 8 of the cover element 7 is placed against the window frame 2, then the mounting bracket 3 comprising the end part 4 with the angled tip 16 is placed behind the outer lateral edge of the window frame 2 and the other end of the mounting bracket 3 is pushed into the groove 14 in the end wall 8 of the cover element 7 so that the mounting bracket 3 extends out from the slot 7 of the cover element 7. The same is carried out on the other side of the window frame, FIGS. 1 and 2.

[0045] Then the end 6 of the curtain wire 1 (which is shown as a hook in the drawing) is fixed in the notch 19 of the fixing element 5 of the mounting bracket 3 so that the curtain wire 1 emerges from the cavity of the cover element 7 through the slot 12. The same is carried out on the other side of the window frame with the other end of the curtain wire (not shown in the drawings).

[0046] Thereupon a cap 13 is placed onto the cover element 7, where the cap forms the second end wall 9 of the cover element 7. In the embodiment shown in the drawing, the cap 13 is fixed with a snap-fit 15. But also an interference fit may be used.

[0047] When in accordance with the second embodiment installing the curtain wire 1 fastening system onto the window frame 2 in front of a glass pane or a glass package 20, the mounting bracket 3 comprising the end part 4 with the angled tip 16 is placed behind the outer lateral edge of the window frame 2. The same is carried out on the other side of the window frame, FIGS. 3 and 4.

[0048] Then the end 6 of the curtain wire 1 (which is shown as a hook in the drawing) is fixed in the notch 19 of the fixing element 5 of the mounting bracket 3. The same is carried out on the other side of the window frame with the other end of the curtain wire (not shown in the drawings).

[0049] Then the cover element 7 comprising the groove 14 in the end wall 8 is pushed onto the fixing element 5 of the mounting bracket 3 so that the mounting bracket 3 extends from the slot 11 and the curtain wire 1 extends from the slot 12. The same is carried out on the other side of the window frame.

[0050] In the present embodiment the curtain wire 1 is made of flexible material, such as spirally wound spring wire, which has a plastic coating and which has openings at both ends. A hook or a loop is screwed into those openings forming the end 6 of the curtain wire 1 and which is used to attach the curtain wire to the fixing element 5 of the mounting bracket 3.

[0051] The curtain wire may also be braided cable or string, which is stretched by its ends between the fixing elements of the mounting brackets on the left and right vertical parts of the window frame.

[0052] It is obvious to the person skilled in the art that within the scope of attached claims the invention may have embodiments other than those described above.
