An adjustable vehicle screen utilizes a telescoping frame having a slot disposed in the innermost surface thereof so as to permit an elastic-like screen member to have the marginal edges thereof pass therein. The free edges of the screen are captured within the tubular telescoping frame. The frame may be dimentional so as to accommodate various window openings in motor vehicles by allowing the screen to expand or contract in size in conformity therewith. One embodiment of the invention utilizes a pair of hinges joining together a pair of U-shaped frame members so as to permit the screen element to be folded up when not used. Such U-shaped frame members each have telescoping components thereby permitting the apparatus to adjust in size for various window openings. A portion of the frame is provided having a protrusion extending outwardly therefrom so as to be installed within the groove located in the frame of the vehicle in which the uppermost edge and the side edges of the window may reside. The lowermost region of the frame portion is provided having a channel therein adapted to receive the uppermost regions of the glass window of the vehicle, when the glass window is in a retracted position. The protrusion portions and the groove portion serve to maintain the frame securely in the window opening when the screen is thus installed therein.
An adjustable vehicle screen comprising a closed frame, said frame being disposed residing in a plane, said frame including a plurality of alternate elongated elements, said elongated elements slidably, telescopingly engaged to one another, a screen, said screen including a plurality of screen elements, each said element having a plurality of circularly shaped turns each disposed having a coil-like shape when there is an absence of forces applied thereto in an outward radial-like fashion, said plurality of elements disposed in side by side parallel relationship adjacent one another, adjacent said elements each having said turns thereof interlocking with each other, wherein each of said turns of said each element may be disposed at selected distances apart from one another along the length of said coil-like shape, means to selectively shorten and lengthen said distances upon first opposed forces being applied to the ends of said plurality of elements, means to selectively shorten and lengthen the distance separating the longitudinal axes of said each of said adjacent elements at selected distances apart when second opposed forces are applied to said adjacent elements, means to dispose said circularly shaped turns into elliptically shaped turns when said second opposed forces are applied to adjacent elements directed away from one another, wherein said first opposed forces are at right angles to said second opposed forces, the marginal edges of said screen slidably engaged and captured from disengagement with said frame, said screen residing within said plane, whereby said frame and said screen may be simultaneously, selectively, independently and concurrently expanded and contracted in the length of said coil-like shape and the distance defined by end most said elements upon the application of said first and said second opposed forces to selective portions of said marginal edges of said screen, wherein said frame and said marginal edges of said screen are configured to be in a closed polygonal shape.
