  • Patent number: 7013525
    Abstract: A wiper blade for cleaning the surface of glass in a vehicle utilizes a wiper-providing body including a spine portion and a wiping element for engaging the surface of glass to be cleaned and an elongated cleaning element which is mounted for movement relative to the spine portion. Juxtaposed magnetic devices are secured within the spine portion and the cleaning element for biasing the cleaning element away from the spine portion of the wiper-providing portion so that during use of the wiper blade, the cleaning element is biased toward the glass surface by the repelling forces of the magnetic devices and is maintained in a spaced relationship with the spine portion so that during use of the wiper blade, the cleaning element is permitted to shift in position relative to the wiper-providing element and the spine portion.

  • Patent number: 7007340
    Abstract: A wiper (22) has a length (L) which is divided into a distal segment (D), a middle segment (M) and a proximal segment (P). Wiper (22) has first and second wiper blades (26, 28), each having wiping faces (26c, 28c) in contact with a surface S and defining therebetween a channel (30). One or both of the blades (26, 28) have one-way water-passage formations thereon along the middle segment (M) of the length (L) thereof. Such formations, e.g., notches (34,36), are dimensioned and configured to permit passage of water through, e.g., the second blade (28), to the channel (30) when the second blade (28) is moving in a first direction, and to prevent passage of water through notches (34) when the second blade is moving in a second direction opposite to the first direction. Conversely, the first blade (26) formations, e.g.

  • Patent number: 6973697
    Abstract: This invention relates to a novel automobile wiper holder with pressurized stability, warning effect and variable size, at least constituting the blade holder, the first connecting panel, the second connecting panel, the third connecting panel and the holder seat. The pressurized panel is design to be mounted on the both sides of surface of the holder seat so as to keep the wiper blade always pressed close to the windshield during the driving irrespective of the wind pressure applied to the wiper holder. The holder seat has a projected hollow body to house the a circuit linking to the lighting elements which will illuminate the transparent or translucent pressurized panel or semicircular tube in an effort to bring to the attention of the driver the poor vision in the bad weather. The second and the third connecting panels provide a plurality of retaining holes or retaining slides in collaboration with the cover panel for employing variable size of wiper blades.
