Abstract
A window closure system comprising a closure member for connecting a window sash to a window frame. The closure member comprises a corrosion resistant elongated rigid rectangular body portion formed from a single continuous stainless steel sheet or a single continuous stainless steel alloy sheet. The body portion having a planar layer and two metal members folded over into substantial abutting contact with the planar layer. One or more keeper members are used to engage the metal layers and prevent their movement from away from the abutting contact with the planar layer. The closure member may comprise part of a swivel arm, a hinge arm and a tie bar.

A corrosion resistant window closure member comprising,
- an elongated rigid rectangular body portion having substantially parallel longitudinally extending edges, said body portion comprising a single, continuous, stainless steel sheet having a first generally planar layer and two juxtaposed generally planar metal members, each of said metal members extending from a respective one of said longitudinally extending edges and being in substantial abutting contact with said planar layer between said edge and an end portion thereof,
- a bore extending through the planar layer between the metal members,
- a keeper positioned in the bore and engaging a portion of each of the metal members and substantially preventing the metal members from moving out of abutting contact with the planar layer,
- the closure member being mounted to one of a window sash and a window frame for selective movement to engage the other of the window sash and window frame for preventing movement of the window sash relative to the window frame.
