Abstract:

A window hinge having a track mountable to a window frame, a sash arm mountable to a window sash, and a plurality of pivotally interconnected links connecting the track to the sash arm to allow pivotal movement of the sash relative to the window frame. At least one of the links is pivotally connected to a shoe movable on the track and another of the links is pivotally connected to a block. The block includes a projecting stud and is elastically deformable to allow sliding of the block in the track with the stud retracted until snappingly securing the stud in a mounting slot in the track during field assembly. The hinge is mounted by first fixing the track to a window frame and the sash arm to a window sash, thereafter sliding the shoe and the block in the track to dispose the block stud adjacent the track slot, then fixing the block to the track with the block stud in the track slot.

Abstract:

A support arm for a pivoted window to hold the window open until such time as the locking mechanism for the window is manually released. The support arm has a sequencing latch mounted on one of a pair of sliders that are telescopically mounted relative to each other and a pivoted lock lever is pivoted on the other slider. In moving the sequencing latch to an active latch or lock position, the lock lever is pivoted from an active to an inactive position and is not effective to remove the sequencing latch in response to any movement of the sliders relative to each other until such time as the lock lever is manually moved from the inactive position to an active position wherein, upon relative movement between the sliders, the lock lever can engage and move the sequencing latch from the latch position to an unlatch position.
