Durable Folding Automobile Sunshade and Method of Manufacturing Same

摘要

In order to manufacture an automobile folding sunshade, continuous strips of a roll material such as thin cardboard are supplied at the same time that discrete panels of reinforcing material that is too stiff to be rolled are supplied. The strips and the discrete panels are laminated between top and bottom sheets of preferably highly reflective material such as mylar coated bubble insulation. The resulting laminate material is then cut to the correct size and shape to fit into the windshield of an automobile. The sunshade has upwardly extending tabs at the top that include the reinforced panels. The tabs engage the sun visors of an automobile. The result is an economical yet highly durable folding automobile sunshade that is easily installed in, and removed from, a windshield of a car or truck.

主权项

1. A folding automobile sunshade comprising:
a bottom sheet of flexible material, the bottom sheet having a top edge and a bottom edge opposite the top edge, the top and bottom edges of the flexible sheet defining top and bottom edges of the folding automobile sunshade; a plurality of stiffening strips arranged on the bottom sheet and extending in a direction from the bottom edge to the top edge, the stiffener strips being sufficiently flexible that they are capable of being rolled up onto a roll of stiffening strip material; at least one stiffener panel, the stiffener panel being sufficiently stiff that it is incapable of being rolled up into a roll of stiffener panel material, the stiffener panel extending generally in parallel with the stiffening strips; and a top sheet of flexible material over the bottom sheet, the stiffening strips, and the stiffener panel, and adhered thereto.
