Abstract:
A support mechanism for a window assembly having a sash tiltable for cleaning, said sash having opposed lateral edges and a tilting axis extending between said lateral edges proximate a lower edge of said sash, and an upper edge of said sash being rotatable about said axis when said upper edge is unrestrained, said support mechanism comprising:a cord of extended length having a first end for connection to said sash proximate one said lateral edge; a tensioning unit for mounting to a frame of said window assembly and connected to said cord; a guide element for connection to said frame of said window assembly and for defining a path for said cord between said attachment to said sash and said tensioning unit, said tensioning unit, when said support mechanism is installed in said window assembly, producing tension in said cord when said sash is in a position tilted about said axis from a normal restrained position that is generally parallel to said frame of said window assembly, said cord supporting said sash stationary at a tilted position, said stationary tilted position being determined at least in part by an active portion of said extended length of said cord; a cord adjustment mechanism connected to said cord for adjusting said active portion of said length to allow selection of said stationary tilted position.
