发明名称 Foot-operated, window-raising device for a window having a sliding sash and method
摘要 A foot-operated, window-raising device for a window having a sliding sash, with the window being positioned a predetermined distance from a support surface. The foot-operated, window-raising device includes at least one pulley mounted to a frame member adjacent to the window and a moveable platform. A cord is threaded through the pulley and a first end is attached to the sliding sash. The cord is secured to the platform such that movement of the platform in a first direction causes the cord to open the sliding sash. The cord has a predetermined length which positions the platform between the window and the support surface at a height which is accessible by a user's foot. By stepping on the moveable platform, the platform moves in a first direction causing the cord to open the sliding sash.
