  • Pivoted fitting or turn-and-tilt fitting for windows, doors
    Patent number: 5052079
    Abstract: A pivoted fitting or turn-and-tilt fitting for windows, doors or the like comprises a bottom turn-and-tilt bearing and a top pivot bearing, both bearings being in each case constructed with two links in order to shift the pivot axis during pivoted opening of the leaf frame. In order to relieve the links of the weight of the leaf, it is suggested that the leaf frame be supported on the fixed frame via an arrangement which is independent of the links of the two pivot bearings.
