Patent ID: 8141299

Claim:
A casement window comprising: a frame defining an opening; a sash operably coupled with and disposed in the frame, the sash selectively positionable between a closed position in which the sash closes the opening defined by the frame and an open position; and a snubber assembly for resisting deflection of the window sash in the frame when the sash is in the closed position, the snubber assembly comprising: a pair of snubbers, each snubber having a base portion and a hook-shaped flange extending from the base portion, the base having a mounting surface for engaging the sash or the frame and further presenting a generally planar interface surface oriented substantially perpendicular to the mounting surface, the flange presenting a generally planar contact surface on a tip thereof, the contact surface being oriented in substantially the same plane as the interface surface; wherein one of the pair of snubbers is mounted to the frame with the mounting surface engaging the frame and the other of the pair of snubbers is mounted to the sash with the mounting surface engaging the sash, the snubbers disposed such that when the sash is in the closed position, the contact surface of the hook-shaped flange of each snubber engages the interface surface of the other snubber, and wherein the hook-shaped flanges of the snubbers are adapted for releasable engagement when negative pressure is applied to the window sash.
