A base pivotally mounts a handle member to the window frame.  A coupler link is pivotally secured at one end to the handle member and has a flange at the other end pivotally secured to the tie bar.  The flange has a narrow portion with a first width adjacent the coupler link and a wide portion with a second width spaced from the coupler link.  The tie bar includes an opening with a substantially circular por-tion having a diameter greater than the first width and less than the second width, and a slot portion wider than the second width.  The coupler link is positioned at a non-operational angle relative to the tie bar during assembly to allow passage of the flange wide portion through the tie bar opening slot portion.  The flange wide portion thereaf-ter holds the coupler link to the tie bar with the flange narrow portion pivotable within the tie bar opening circu-lar portion during operational (i.e., locking and releas-ing) pivoting.

Title: Window unit nailing fin and corner lock
Inventor: HAGEMEYER BRUCE A
IPC: E06B1/62
Filed: 1991-12-20
Granted: 1995-06-27
Abstract: A one-piece metal frame fin is locked to the wooden frame members of a window unit by exterior cladding.  A notch in the frame members receives the inner portion of the nailing fin while the outer portion of the fin is recessed into the wood when the fin is in its closed position for storage, transport and use in abutting frame members of multiple window units.  An L-shaped corner nailing fin is carried on one of the frame fins and can be pivoted into locking engagement with the adjacent frame fin during installation of the window unit.  In the case of joined multiple window units a mullion cover extends over the adjacent ends of the frame nailing fins and is locked to the outer nose portion of the exterior cladding.
