ABSTRACT:
A connection for adjustably holding a sash arm and a support arm in pivotally connected relationship, including a sash arm having a first cylindrical opening, a support arm having a second cylindrical opening at one end, and a stud. The stud includes a pivot portion with a cylindrical shaft extending through the second cylindrical opening, a rivet portion extending from one end of the cylindrical shaft through the first cylindrical opening and eccentric to the pivot portion cylindrical shaft, and a head on an end of the rivet portion spaced from the cylindrical shaft wherein the head and the one end of the cylindrical shaft engage opposite sides of the sash arm to frictionally secure the stud against pivoting relative to the sash arm. The first cylindrical opening includes a countersunk hole on the side of the sash arm attachable to a window sash, wherein the rivet portion head is formed substantially entirely in the countersunk hole. A plastic washer is disposed about the cylindrical shaft between the sash arm and support arm, and has an outer diameter which is less than the width of the sash arm and support arm. A hexagonal shaped aperture is formed on the shaft head and is engageable with an L-shaped hex wrench to allow for adjustment of the pivotal connection by pivoting the stud between frictionally secure positions relative to the sash arm.
