  • Patent number: 5035460
    Abstract: An automobile window protector comprises a substantially planar, generally rectangular sheet of flexible material held in an open configuration by an elongate curved strip of spring-like material attached to the sheet. Suitable shapes for the elongate strip include an arcuate shape, an arcuate shape with a flattened midportion, a U-shape, a C-shape, and a generally rectangular or oval closed loop. The window protector can be reduced to a compact configuration by twisting and folding it upon itself. A loop of elastic material attached to a midpoint of one of the longer sides of the sheet serves to hold the protector in its compact configuration when the loop is slipped over the folded protector. At or near each corner of the protector is a strip having a connector at its distal end to facilitate attachment of the shield to an automobile.

  • Patent number: 5024262
    Abstract: An automobile window sunshade having a particularly simple structure and capable of easily being folded into a compact configuration for storage is provided. The sunshade comprises a single elongated loop of a thin strip of spring-like material covered by a sheet of one or more layers of a flexible material. The shape of the elongated loop can vary from a generally rectangular shape with slightly rounded corners to an oval or generally elliptical shape. One or both of the two major surfaces of the sheet are adapted to reflect light and heat radiation from the sun. In its normally open configuration, the sunshade is placed against the inside surface of an automobile windshield or window with a reflective surface facing outward. The single elongated fabric-covered loop of the sunshade can be easily twisted and folded into a compact configuration consisting of a series of smaller concentric loops and fabric layers.
