Adjustable casement hinge

Abstract

A connection for adjustably holding two window hardware members in pivotally connected relationship, including a first hardware member with a first cylindrical opening, a second hardware member with a second cylindrical opening, and a stud. The stud has a flange having two substantially parallel faces and a peripheral surface therebetween, with a rivet portion projecting from one face and a pivot portion projecting from the other face. The rivet portion includes a cylindrical neck extending through the first cylindrical opening and a head on the end of the neck, the flange and the head engaging opposite sides of the first hardware member to frictionally secure the stud against freely pivoting relative to the track. The pivot portion includes a cylindrical shaft eccentric from the cylindrical neck and extending through the second cylindrical opening. A C-ring is disposed in an external peripheral groove in the pivot portion to secure the second hardware member thereto for pivoting about the cylindrical shaft. A part of the C-ring is in the peripheral groove and a part extends radially beyond the pivot portion periphery when the C-ring is in a securing position. The peripheral groove has a depth to enable deformation of the C-ring by movement of the spaced-apart ends towards each other to a release position in which substantially all of the C-ring is in the peripheral groove. The stud flange peripheral surface is engageable with a tool to allow for adjustment of the pivotal connection by pivoting the stud.
