ABSTRACT:
An arrangement for tiltably mounting a lateral portion of a window sash in a track of a window frame for sliding longitudinally of the track and for tilting out of the plane of the window frame includes a mounting slide received in the track and including a main portion having an opening that receives a mounting region of a shank portion of a bearing element. The main portion further has two arms which depend from a top region of the main portion and have holding regions which embrace a spreading region of the bearing element. The spreading region includes two flats in an otherwise cylindrical outline, these flats facing the holding regions while the window sash is in the plane of the window frame such that retaining regions of the arms are spaced from side portions of the track and the mounting slide is free to move along the latter. When the window sash is tilted, the cylindrical outline of the spreading region presses the arms and thus the detaining regions toward and against the side portions of the track, thus arresting the mounting slide in position. The detaining regions are separated from the holding regions by respective slots which permit limited relative elastic displacement therebetween.
