Abstract
A combined window and vent unit which is vandal resistant yet is versatile in its ventilation and insulation capabilities. There is a freely movable window panel which is positioned in a rigid frame structure without the use of any hinge members yet can be retained therein in an intermediate ventilating position. The frame structure for the vent unit is easily assembled and the panel members and screening can be easily repaired.
Claims7
A combined window and vent unit comprising:
- a first frame structure including top and bottom wall and side wall portions;
- a second frame structure positioned inside the first frame;
- combined angular guide and support surfaces positioned adjacent the side wall portions and sloping downwardly toward the bottom wall, said guide surfaces terminating in a preselected distance from the second frame;
- a window panel member freely carried by the first frame structure and between the angular guide surfaces and the second frame structure;
- and
- insulative means connected to at least one of the panel member and the second frame structure;
- whereby the angular guide surfaces provide support for the panel member when in a venting position and a compressive hinging action between the insulative means of the panel member and the second frame structure when in a closed position.
