Pivot bar for sash windows

A tiltable window sash assembly comprising:

• a window frame;
• an upper sash and a lower sash mounted within the window frame, the lower sash further comprising:
• a first stile and an opposite second stile, the first stile including a first stile wall, a second stile wall, and a bottom stile wall extending between the first and second stile walls, the first stile further including a stile channel formed between the first and second stile walls;
• a top rail and an opposite bottom rail, the top and bottom rails each extending horizontally across between the first and second stiles together forming a sash frame, the bottom rail further including a first rail wall, a second rail wall, and a bottom rail wall extending between the first and second rail walls, the bottom rail further including a rail channel formed between the first and second rail walls, wherein the stile channel and rail channel communicate with one another at a corner of the sash frame;
• a pivot bar having a first leg segment and a second leg segment, the first leg segment positioned within the stile channel and coupled to the bottom stile wall, and the second leg segment positioned within the rail channel and coupled to the bottom rail wall such that the pivot bar wraps around the corner of the sash frame whereat the first stile and bottom rail meet, wherein the first leg of the pivot bar further includes a first leg segment extending along a first plane and a second leg segment extending along a second plane parallel to the first plane, and wherein the first leg segment and the bottom stile wall together enclose a pocket therebetween;
• a latch mechanism coupled along the top rail, the latch mechanism actuatable to disengage the lower sash from the window frame, wherein the lower sash is pivotable relative to the window frame about the pivot bar when the latch mechanism is actuated;
• and
• further comprising a corner key coupling the first stile and the bottom rail together at the corner of the sash frame, the corner key including a port in communication with the pocket enclosed by the first leg segment and the bottom stile wall, wherein the bottom stile wall further includes an opening in communication with the pocket and the port of the corner key, the opening directing overflow resin material from the corner key into the pocket.

A pivot bar for a tiltable window sash system having a sash with a stile and a rail that are joined at a corner by a corner key, the sash supported within a frame, the pivot bar comprising:

• a first leg extending substantially along a first axis, the first leg having a first leg segment, a second leg segment, and a third leg segment that are arranged end-to-end substantially along the first axis, the first leg segment defining a first plane and the second leg segment defining a second plane that is parallel to the first plane, the third leg segment extending between the first leg segment and the second leg segment to separate the first leg segment and the second leg segment along the first axis;
• a second leg extending from a lower portion of the first leg segment along a third plane, the second leg configured to mount to the rail, the third plane being generally orthogonal to each of the first and second planes;
• and
• a third leg extending from the lower portion of the first leg segment, the third leg arranged generally parallel to the third plane of the second leg, the third leg configured to pivotally attach the sash to the frame;
• and
• the second leg segment having a mounting face configured to mount against a surface of the stile with the first leg segment spaced apart from the surface of the stile to define a pocket therebetween.
