Blade supporting apparatus in wiper apparatus
First Claim
1. A blade supporting apparatus in a wiper apparatus in which a wiper blade mounted to a leading end portion of a wiper arm wipes a window surface in correspondence to a normal and reverse rotation of a wiper shaft integrally mounted to a base end portion of the wiper arm, a middle portion of the wiper blade pivotably supported by the leading end portion of the wiper arm via a pivot substantially orthogonal to an arm length direction so as to freely oscillate, the blade supporting apparatus comprising a supporting member provided in the wiper arm to movably support, toward and away from the window surface, the portion of the wiper blade nearer to the wiper shaft side than the middle portion of the wiper blade, the supporting member having a supporting concave portion formed in the supporting member so as to receive and support the wiper blade and a plurality of ribs extending toward the window surface formed on an inner surface of the supporting concave portion so as to be in linear contact with the wiper blade, and the supporting member supports a blade lever constituting the wiper blade, and a support receiving body insertedly fitted to the supporting concave portion of the supporting member is provided in a supporting portion of the blade lever in a come-off preventing manner and contacting in linear with the plurality of ribs of the supporting member.

Abstract
In a structure in which a middle portion of a wiper blade is pivoted to a leading end portion of a wiper arm via a pivot substantially orthogonal to an arm length direction so as to freely oscillate, and a supporting member supporting a portion closer to a wiper shaft than the middle portion of the wiper blade is provided in the wiper arm, the structure reduces a sliding resistance which occurs due to a movement of the wiper blade toward and away from a window surface. A stabilizer has an upper piece portion and a pair of side piece portions, a supporting concave portion supporting a wiper blade in an outward fitting manner is formed, and a plurality of ribs which extend toward the window surface are formed on inner surfaces of the side piece portions, thereby being in linear contact with outer surfaces of side piece portions of a support receiving body which is fitted to a first lever terminal end portion of the wiper blade.

14. A blade supporting mechanism in a wiper apparatus for a window surface, the wiper apparatus having a wiper arm shaft connected at one end to an oscillation shaft and having a wiper blade connected at the other end, the wiper blade having a wiping blade mounted to a lever arm assembly having a plurality of levers including at least a main lever and a secondary lever pivotally mounted to each end of the main lever, the main lever pivotably mounted to the other end of the arm shaft, the arm shaft made up of at least an arm piece at the other end and an arm portion connected to the oscillation shaft, the blade supporting mechanism comprising:
-
a support receiving body mounted at a pivotal connection of the main lever to a secondary lever closest to the oscillation shaft; and a stabilizer mounted in the arm portion to oppose and receive the support receiving body, wherein a plurality of ribs are formed on a one of inner side surfaces of the stabilizer and outer side surfaces of the support receiving body, the ribs extending in a direction toward and away from the window surface. - View Dependent Claims (15, 16, 17, 18, 19)
