摘要： A locking mechanism for a double hung window includes a strike bracket and a locking member. The strike bracket attaches to the upper window sash, and has an upstanding locking plate with a vertical series of locking hooks, each extending inward and curling downward and back outward. The locking member attaches to the lower window sash, and has a rotatable clasp with a clasp hook extending outward and curling upward and back inward. The clasp hook selectively engages the locking hooks on an inward and downward line of action to clamp the window sashes together against relative movement, both vertical and horizontal.
