发明名称 Window egress assistance handle
摘要 A window egress assistance handle having a base, at least one finger grip with two legs, multiple offset orifice fixation ports for receiving multiple securing devices such as set screws or thumb screws, and a base midline grooved channel receiver. To temporarily install and use the handle, the handle is positioned to envelope an integrated extruded window sash lift in the grooved channel receiver, and the securing devices disposed in the multiple offset fixation port are engaged to create a binding compressive force upon enveloped sash lift. The window can then be lifted or slid by applying force to the finger grips. The handle can be adjusted to the user's strength, size, and dimensions, and installed and removed without use of tools or creating permanent damage to the framework of the window.
