Description

"Fastening system for fall protection"

The invention relates to a fastening system for

Fall protection devices on a window frame or a door frame.

In the case of windows or doors, in particular in the case of patio doors which, as a door, provide a window-like opening outside the floor level, e.g. a so-called French balcony, fall protection is usually in the form of panels,

10 grilles or panes of glass are to be provided. These are usually anchored from the outside in the masonry or are already in the window

or the door integrated.

There is a particular problem with these fall protection systems

15 represents the inability to retrofit existing windows and doors. Retrofitting is particularly problematic if additional shading or shutters must be taken into account, which are not hindered in their function by the fall protection

20 may. This problem occurs when renovating windows and doors, for example. have to be replaced by new windows or doors. Furthermore, there is a problem with retrofitting if e.g. for building law reasons or due to the monument protection, an attachment to a

25 external facade is not possible.

The object of the invention is to provide a fastening system for fall protection which overcomes the disadvantages mentioned.
