Description

[Technical field]

[0001] The present invention relates to a curtain wire fastening system to a window frame, the curtain wire being intended to hang a curtain in front of a window. [Background technology]

[0002] The prior art contains several known curtain wire fastening systems for hanging curtains in front of a window. Usually, suitable hooks or fasteners are used to fasten the curtain wire to the wall, and the fastening point, i.e. the joining point of the two fastening elements, remains visible. The use of this solution may cause injury to the user or damage to the curtain fabric. Furthermore, this type of attachment is visually unappealing.

[0003] GB 2420834 A1 (published 7 June 2006) describes an easy to install curtain fastening system in which a fixing element is covered by a covering element.

[0004] The closest solution known from the prior art is that described in Estonian Utility Model No. EE01264 (Patent Document 2: published 15.12.2014) by the same applicant for a fastening system for curtain wires to a window frame. This system comprises fastening brackets fixed to the window frame at both ends of the curtain wire, one end of said brackets being fastened to the rear of the outer edge of the window frame and the other end of said brackets being formed with a fastening element for attaching the curtain wire. A hollow cover element is attached to cover the fastening bracket. The disadvantage of this solution is that the system cannot be permanently fixed to the window frame, therefore such a suspension system is mainly suitable for light, free-hanging curtains, such as curtains made of voile fabric. Such a fastening system may deform if used to hang heavier curtains, which may damage the edge of the window frame. [Prior art documents] [Patent documents]
