Description
Background of the Invention
1. Field of The Invention
The invention relates to window seals, and more particularly to seals for surrounding sliding windows in automobile door frames.
2. Prior Art
Automobile door frames are no longer assembled and shaped by bending the metal profile in the form of a U-shaped window frame, but are now formed by stamping double door frames comprising an inner panel and outer panel joined together to form a frame for the sliding window. The sealing means around and receiving the sliding window is attached to the door frame and may include finishing trim thereon. This involves numerous problems including increased assembly costs and the introduction of fasteners which can become loose and/or oxidized.
Summary of the Invention
It is an object of the instant invention to eliminate or reduce the disadvantages found in the prior art. This is accomplished by means of the novel structure of the instant invention which includes a pair of shaped, gripping and covering frame elements or enclosures. The frame elements are adapted to the periphery of the openings for receiving the sliding glass window therein and are assembled to the double door frame. This assembly is capable of providing a simple and automatic method of installation and fastening of the sealing frame elements in the opening. A spacer brace is positioned between the frame elements and extends between the two portions of the double door frame. The spacer brace is limited to the upper part and two side portions of the circumference of the window, the window being permitted to slide between the lower sealing/weatherstrip elements into the body of the double door frame. Flocking is provided on the surfaces which contact the sliding glass, and the door includes conventional sliding mechanisms, together with the usual glass installation and handling elements.
Brief Description of the Drawings
The above and other advantages and features of the invention will be better understood from the following description and accompanying drawings wherein:
FIG. 1 illustrates a schematic elevation view in reduced scale of complimentary portions of a door enclosure according to the instant invention with sealing means around the periphery for receiving a sliding glass window;
FIG. 2 is an enlarged cross-section taken along lines A--A of FIG. 1 and showing the lower portion of the door window seal;
FIG. 3 shows an enlarged cross-section taken along lines B--B of FIG. 1 showing the upper and side portions of the window and including a supplemental spacer brace means;
FIG. 4 shows the same cross-section as FIG. 3, but further includes an assembly installed on the double door;
FIG. 5 shows another embodiment similar to FIG. 3, but further includes a decorative trim fastened thereto;
FIG. 6 shows yet another embodiment including a pair of small cellular rubber tubes which are flocked and are substituted for the guiding sealing lips shown in the previously described embodiments; and
FIG. 7 illustrates a transverse cross-section of a conventional slide for guidance of glass automotive windows.
Detailed Description of the Invention
Referring to the figures in the drawing, particularly FIG. 4, a pair of unitary cooperating sealing frame elements 1 and 2 having symmetrical configurations are positioned around the periphery of openings 3 and 4 of the double door frame. The elements and door frame are connected together by a brace 5. The elements are made by means of a known extrusion process and are formed of elastomeric "plastic" material and have a metal center core therein. Each element has "flocked" inner lips integral therewith for contacting the sliding glass window.
The construction of the elements 1 and 2 permit easy installation while one simultaneously tightens a spacer brace 6 which has flocking on the inner face thereof, i.e., on the portion against which the glass window abuts. It should be noted that installation is first facilitated by placing the assembly on the vertical post in an oblique fashion and followed by tilting and sliding, thereby automatically insuring the tightening and fastening of the assembly on each portion of the door up to the free extremities 7 and 8 which abut against the deflector post or an auxiliary element such as the fixture for retaining a rear view mirror.
It will be appreciated, of course, that the installation of the spacer brace 6 is limited to the side and upper portions of the window frame; whereas, the lower horizontal portion has no brace to permit the passage of the glass between the pair of flocked inner lips as in FIG. 2. The flocked inner lips can be replaced, for example, by tubular elements as seen in FIG. 6.
One or both of the sealing elements can be provided with a decorative strip or ribbon 9 which may be, for example, of a polished metal and mat or highly polished metal and which can even be deposited by electrolysis and protected against oxidation and ultraviolet radiation by a transparent film or sheathing, for example, of the type commercially known as "Mylar", a polyester film, or "Tedlar", a fluoride film, with the decorative elements 9 being maintained in a known manner by fastening, adhesive bonding or thermal welding.
Finally, FIG. 7 illustrates a transverse cross-section of a conventional sliding glass automobile window which needs no description and shows the prior art.
While several embodiments of the invention have been described, it will be understood that it is capable of still further modifications and this application is intended to cover any variations, uses, or adaptations of the invention, following in general the principles of the invention and including such departures from the present disclosure as to come within knowledge or customary practice in the art to which the invention pertains, and as may be applied to the essential features hereinbefore set forth and falling within the scope of the invention or the limits of the appended claims.
