ABSTRACT:
A window for use in buildings for housing animals, such as barns, that is openable in two generally perpendicular directions, is provided. The window includes an outer frame secured within an opening in the structure, a middle frame that is pivotally secured to the outer frame, and an inner frame pivotally secured to the middle frame. A first pivoting mechanism includes a pair of hinges that enable one of the frames to be pivoted with respect to the outer frame along a generally vertical axis, and the second pivoting mechanism enables the other frame to be pivoted with respect to the outer frame along a generally horizontal axis. The second mechanism pivots and slides one of the frames in order to open the window for ventilation purposes while enabling the remaining frame to remain closed, thereby preventing the entering or exiting of large objects through the window, such as an animal's head.
