Appl. No.:

10/241855

Inventors:

Donald Lee Thomas - Hampton VA, US

International Classification:

A47H 1300

US Classification:

1603681, 160376, 52202

Abstract:

An inexpensive, lightweight, reusable and detachable or removable insulation device for residential and commercial dwellings and similar heated structures. The device has an inner-portion insulating pad adapted to fit inside of a typical entrance or window unit framing. The device further has an outer-portion insulating pad adapted to overlap the window or entrance framing. The outer-portion insulating pad is provided fasteners so as to be secured to the building wall structure outside of the framing and surrounding the window or entrance framing by. During cold weather months, the present invention will greatly restrict warm air from escaping between small crevices in inept window systems by fitting firmly into window framing using a insulating material, thus creating a thermal barrier and improving the efficiency of the furnace by reducing the demand for electricity or fuel consumption.

Abstract:

A portable, lightweight and detachable photovoltaic window system affording a resource for converting solar power in existing buildings and similar structures. At least one photovoltaic panel is interconnected to a building window or entrance casing or directly to a window pane through use of lanyards, hook and loop fasteners, or suction cups. Solar energy is captured from direct sunlight incidental to the location of the window. A panel may be removably supported by a fabric material interconnected to an interior wall via hook and loop fasteners. An inverter converts energy from DC to AC for powering electrically driven devices. A pocket is provided on the panel support for temporarily storing the auxiliary devices. This system enables a person with little knowledge of solar energy equipment a convenient and inexpensive method to convert sunlight into useful energy without major alterations to the building or window unit being used as a light-source.
