Abstract:

A window roller apparatus comprising a cradle, a housing pivotably installed in the cradle, and at least one roller wheel rotatably installed in the housing. Cradle side walls are formed with opposite inwardly-opening cradle side wall recesses, and respective housing side walls are formed with opposite inwardly-opening housing side wall recesses and with opposite outwardly-projecting bosses configured to pivotably engage the respective inwardly-opening cradle side wall recesses. The at least one roller wheel has an axle that engages the housing side wall recesses. A resilient pad is positioned on the cradle bottom wall between the cradle and the housing, the pad being of a sufficient size and thickness to at least partially engage the housing and effectively bias the housing toward a parallel orientation relative to the cradle while allowing for non-parallel operation of the housing relative to the cradle as dictated by operational constraints on the window roller apparatus.
