Abstract
A pivoting and sliding device is provided which incorporates a unique cam and frictional locking assembly. Rotation of a cam in a sliding block, slidably mounted within a track, produces lateral expansion and normal biasing of the slide block to frictionally engage four sides of the slide block with respective opposing track surfaces. A vertical or horizontal window or door sash may be pivoted out of the plane of the frame about a pair of slide blocks rigidly locked to the frame.
