A continuous hinge attached to the windshield of a cycle to permit rotation of the windshield from the upright protective position forward and downward to any selected position permitting partial or complete exposure of the rider to the wind. A pair of elongated plates continuously hinged together along one longitudinal edge conform to the shape of the windshield along the opposite edge. Perpendicular flanges along the conforming edge of the hinge secure the hinge to the windshield which is sandwiched between a backplate and the flanges and is separated therefrom by rubber strips. Rotational position of the windshield is provided by selective matching perforations on end plates secured to the ends of the hinge plates or by a notched slidable curved member from one hinge plate secured by a protruding bolt in the other hinge plate. The continuous hinge may be mounted between sections of a windshield, between a windshield and a fairing, or between a windshield and the fork tubes of a cycle by an instantly removable pin and locking sleeve connection. 1. Technical Field My invention relates to windshields for velocipedes and in particular to windshields which may be reversibly moved into and out of the path of the wind. 2. Background Art Prior art has demonstrated some collapsible windshields for cycles, but none of the prior art devices provide a system which can readily be applied to an existing windshield, especially a curved windshield. Many of the prior art foldable windshields provide heavy frame structures which obscure the view of the rider or light material which is not clear for viewing. None of the prior art devices provide an easily adjustable pivoting windshield which maintains the rider in a wind-free condition. Either they are very small devices or the hinge system permits air to pass through onto the rider. Most prior art devices are cumbersome and time consuming to install and become permanent fixtures on the cycle. DISCLOSURE OF THE INVENTION The present invention provides a hinge system for a folding windshield which may readily be applied to any existing windshield to transform it into a pivoting windshield by securing the hinge plates to the windshield and securing the windshield horizontally in a line between the hinge plates. The curved edges of the plates may be custom-shaped to fit windshields made by any manufacturer. The present invention provides a simple horizontal hinge and plates located well below the line of vision so that the rider's vision is not obscured by the device. Providing curved edges on the hinge plates the device may readily be applied to clear unobstructed curved windshields. By providing a continuous hinge across the entire line of separation between windshield sections, no wind may pass between the upper and lower windshield sections. When the windshield is tightly secured to an adequate fairing, no wind hits the rider directly. Further provided by the present invention is a means to install or remove the foldable windshield instantly within less than a minute.
