member (2, 9),
Central flat member (5) which is hingedly connected at the bottom to the said first
and second pillar members (2, 9),
Plastic molded metallic insert (6) provided on said central flat member (5),
Insert hole (7) with thread provided on the said plastic molded metallic insert (6),
Snap member (8) provided on the edge portion of the said central flat member for
locking nut plate with said first and second pillar members (2,9).
Boss member (10) provided on the surface of the said upright leg member (1),
Hole (11) provided on the said boss member for mounting,
Extended hanger member (12) extending from top edge of said upright leg portion
preferably perpendicular to the surface of the said upright leg member,
Flat surface (13) of said extended hanger member.


Said hinge member (4) provided on the first and second pillar member (2, 9) extended perpendicularly from the said central base portion (3) which rotates about its axis to provide flexibility to insert the side of the said bracket. This facilitates easy insertion of the window winding glass in the said bracket.
Plastic molded metallic insert (6) which is M6 screw insert. Said M6 screw insert use to get engaged in the said plastic molded metallic insert (6) which clamps said glass with window winding regulator.
