| 摘要 |
The present invention discloses a wiper blade, comprising a frame type long strip skeleton, a connector to be connected to a wiper arm of an automobile and a rubber strip. The skeleton includes one elastic main beam. The body of the main beam has a curved locus, continuous concave downward curve, both end portions of the main beam register with the curved locus and a middle portion of the main beam registers with or deviates from the curved locus. The skeleton includes one or two elastic sub beams, located below and approximately parallel to the main beam which supports the rubber strip. Between the main beam and the sub beams is a means to constitute various frame structures or to adjust a distance between them so that the pressure applied along the entire length of the wiper blade to a windshield can be distributed evenly as far as possible. |

1. A wiper blade comprising:
a frame type long strip skeleton for supporting the wiper blade; a connector which is provided on a middle portion of the long strip skeleton so as to be connected to a wiper arm of an automobile; and a rubber strip supported or hung by the long strip skeleton, the long strip skeleton is in an arched shape and has a bending elasticity, in use, a concave surface of the wiper blade is pressed toward a windshield glass of the automobile, since the wiper arm applies pressure downward, the rubber strip comes into contact with the windshield glass, and due to reaction force of the windshield glass, the wiper blade is changed in its curvature and the rubber strip comes into contact over its entire length with the windshield glass so that rainwater on the glass can be wiped off, wherein the long strip skeleton includes one elastic main beam and two elastic sub beams which are located below the main beam and are horizontally parallel to each other and approximately parallel to the main beam, in a free state, a body of the main beam has a curved locus in which a specific smoothly continuous curve is concave downward, both end portions of the main beam register with said curved locus and a middle portion of the main beam deviates from said curved locus, a plurality of hanging hooks which are provided to the main beam connect the sub beams to the main beam to form the long strip skeleton, the rubber strip is supported or hung by the sub beams, and the middle portion of the main beam of the long strip skeleton is fabricated into one to three concave-upwardly deformed segments which are integrated with the main beam but deviate from the curved locus therein of the main beam, or the middle portion of the main beam of the long strip skeleton is fabricated into one to three substantially straight deformed segments which are integrated with the main beam but deviate from the curved locus therein of the main beam, or the middle portion of the main beam of the long strip skeleton is fabricated into one to three concave-downwardly deformed segments which have a curvature larger than that of the curved locus therein of the main beam and which are integrated with the main beam but deviate from the curved locus therein of the main beam. |
