Patent number: 4694608Abstract: An improved security bar system for louvered windows is disclosed. The window unit has louvered blades which pivot on horizontal stub shafts.The security bars are mounted on the stub shafts where the louver blades hide them from view and provide an esthetically pleasing window unit. Each security bar has a hardened steel rod with holes bored in each end for receiving the stub shafts and a hardened steel sleeve which freely rotates on the steel rod and covers the rod and stub shafts. The steel rod freely rotates on the stub shafts which are themselves freely rotatable. Therefore, any attempts to cut the security bar will cause the steel sleeve to rotate. Should the steel sleeve be held stationary and cut, the covered steel rod will rotate due to the action of the saw blade.Type: GrantFiled: June 2, 1983Date of Patent: September 22, 1987Inventor: Earl B. Lambert

Patent number: 4292763Abstract: Energy-conserving window blinds are provided. The blinds are fabricated from coupled and adjustable slats, each slat having an insulation layer and a reflective surface to face outwardly when the blinds are closed. A range of desired light and air transmission may be selected with the reflective surfaces of the slats adapted to direct sunlight upward toward the ceiling when the blinds are open. When the blinds are closed, the insulation of the slats reduces the heat loss or gain produced by the windows. If desired, the reflective surfaces of the slats may be concave. The edges of the slats are designed to seal against adjacent slats when the blinds are closed to ensure minimum air flow between slats.Type: GrantFiled: December 7, 1979Date of Patent: October 6, 1981Assignee: The United States of America as represented by the United States Department of EnergyInventors: Paul R. Barnes, Hanna B. Shapira
