Coupling device for glass or metal parts

Abstract

A coupling element comprising elongate thermo-plastic strip material structured to provide that, on application thereto of heat in the range from about 300.degree. to about 500.degree. F. the outer portion thereof becomes fluidly adhesive, and is particularly adapted thereby to quickly form a ready bond and a clean seal between different materials, especially between glass and metal parts. While under the application of heat in the range specified, the outer portion of the element becomes fluidly adhesive, the inner or core portion of the element retains, as originally provided, an essentially stable form which accommodates and conforms to the contour of an applied load. On self cooling in place the strip coupling device provides a uniquely complete and extremely strong bond and seal between parts of unlike materials. In preferred embodiments and applications the invention provides for an improved installation of a window, windshield or like unit. Elements of the invention are particularly distinguished by their reversibility. Once an element is in place and serving as a bond, it need merely be subjected to heat in the prescribed temperature range of 300.degree. to 500.degree. F., under which conditions the outer portion of the element becomes fluid while the stability of the core thereof is maintained. This enables that the element may be quickly and easily removed from between the parts for which it formerly served as a bond.
