ABSTRACT:
A window includes a sash movable between closed and open positions while pivoting on a pair of slides which are vertically movable along the respective side posts of an outer frame. For pivotally connecting the sash to each slide, a pair of axially aligned longitudinally spaced sleeves are mounted on the top edge of the sash, one of the sleeves slidably receiving a pivot pin projecting from the slide. Rotatably arranged between the sleeves is an adjustor ring having a key projecting into the interturn spacing of a helical compression spring mounted within the sleeves and secured at one end to the pivot pin. The contact force of the slide on the side post is adjustable by the rotation of the adjustor ring relatively to the sleeves.
