Abstract: A portable windshield assembly for a recreational vehicle such as a golf cart includes a pair of rigid windshield panels each received in a frame. Each frame is defined by support rails around the periphery of the panels. The inner side rails of the windshield panels are pivotally coupled together by a webbed joining hinge. The outer side rails of the windshield panels are coupled by webbed hinges to an upright assembly defined by truss panels that support the windshield panels in an upright position on the vehicle cowling. The assembly is mounted to the cowling by clamps that couple the truss panels to the rear marginal edge of the cowling. Hooked extendible cords are provided to secure the windshield panels in position on the cowling. T-shaped stabilizing clips engage upper and lower support rails of each windshield panel frame at the joining hinge thereby rigidifying the structure.
