A coupling element comprising elongate thermo-plastic strip material structured to provide that, on application thereto of heat in the range from about 300°to about 500°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°to 500°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.

A coupling device, having special application to creating a bond between metal and glass, including an element physically comprised of stable flexible thermo-plastic material, said element being constituted of materials which in a temperature range including from about 300°to about 500°F. are constructed and arranged to provide said element with an internal or core portion of thermo-plastic material which has a stable load accommodating form and an external portion defining its outermost surface having a fluidly adhesive form. A coupling device, comprising a relatively solid body member of thermo-plastic material having an elongated strip-like form, said member being flexible to provide for a contoured installation thereof on one part to form a bond and a seal between said one part and another superposing part seating on the said body member, said body member being structured and of a composition such that under the influence of a temperature in the range of 300°to 500°F. it includes a relatively stable internal or core portion adapting, but only to the degree necessary, to the contour of an applied load and an external outer surface portion which has a fluidly adhesive form, said body member having an initial cross-sectional outline of one configuration a portion of which is oriented in use to seat to said one part while the other part abuts an opposite portion, and means within said body member for disseminating heat through the interior thereof and to its outer surface to a level in a range from about 300°to 500°F. under the influence of which only the external portions of said body member achieve a fluid state and said fluid outer surface portions have an adhesive form which serves to provide for a bond of said body member to and between said parts in contact therewith, said body member being adapted under the influence of an applied load to assume a different cross-sectional outline providing opposing faces thereon which achieve a wide sealing and adhering contact with said parts while said body member retains the cross-sectional configuration of a solid by reason of its stable core and said heat disseminating means provides means for re-heating said body member after the cooling and bonding thereof, said body member being constructed and arranged when subjected to re-heating at a level of 300°to 500°F. to reassume a fluidly adhesive form at its outer surface portions only, whereby to facilitate the stripping of said body member from and between said parts.
