ABSTRACT:
A supporting bracket for windows which can be used on any side of a window and which can be mounted using existing central mount installation tooling is disclosed. The supporting bracket uses dual sided containment of the vent bar end for preventing sash play and uses camming surfaces to allow for immediate sash pull in which prevents weather-strip problems and prevents the supporting bracket from binding during an opening operation. In some embodiments, an end cap engages opposite sides of a symmetric vent bar end. In another embodiment, a pin attached to the vent bar is engaged on opposite sides by a track formed within the main track of the supporting bracket. In all embodiments, the vent bar and the link pivotally connecting the vent bar to the track are prevented from moving in a direction opposite the direction of opening during an opening operation. The arms of the supporting bracket may have fully rounded edges for preventing binding between adjacent arms during load. Also, the vent bar end and corresponding structure for dual sided containment in each embodiment are symmetrically shaped so that the supporting bracket may be utilized on any side of a window.
