Window hinge assembly and methods

A method of protecting a hinge pin of a window hinge assembly, the method comprising:

• attaching a base of a track assembly to a window frame, the track assembly comprising a shoe track, wherein the base extends along a track axis from a hinge pin end to a shoe track end, and wherein the shoe track extends along the track axis, and wherein the shoe track extends from the shoe track end towards the hinge pin end,
• attaching a base end of a hinge pin to the base proximate the hinge pin end of the base, the hinge pin comprising an upper end distal from the base;
• engaging a shoe engaged with the shoe track, wherein the shoe is configured to slide along the shoe track end the shoe is restrained from moving transverse to the track axis when the shoe is slidably engaged with the shoe track;
• attaching a sash arm to a rotating sash that is attached to the window frame, the sash arm extending from a shoe end to a distal end, wherein the shoe end is pivotally coupled to the shoe;
• pivotally connecting a sash end of a connecting arm to the sash arm at an intermediate location spaced from the shoe end of the sash arm and pivotally connecting a hinge pin end of the connecting arm to the hinge pin, wherein the connecting arm rotates about a pin axis extending through the base end and the upper end of the hinge pin when the shoe moves along the shoe track and the sash arm is connected to the connecting arm;
• and
• restraining the upper end of the hinge pin above the base of the track assembly from movement relative to the base by locating the upper end of the hinge pin in a hinge pin bore located in a support portion of a hinge pin support attached to the base, wherein the support portion extends above the base, wherein pivotally connecting the connecting arm to the hinge pin comprises positioning the hinge pin in an opening in the connecting arm proximate the hinge pin end of connecting arm such that the hinge pin end of the connecting arm is located between the support portion of the hinge pin support and the base of the track assembly.
