STRUCTURE OF WINDSHIELD WIPER
First Claim
1. A structure of windshield wiper, comprising:
- a wiper blade assembly, which has a central portion forming a positioning section, the positioning section comprising a coupling bar fixed at a central portion thereof; and
a retainer, which is in an elongate configuration having a front end portion forming a curved shape, the retainer forming a mounting hole in a top of the front end portion and a notch rearward of the mounting hole, the notch comprising a mounting bar fixed therein, the retainer having a rear end portion forming a lower step section, on which vertical positioning tabs are formed, the lower step comprising an engagement slot and an engagement rib respectively formed in front and rear sections of each side face of the lower step section, the lower step section having a bottom forming a coupling section, whereby the coupling section is attachable to the coupling bar of the positioning section of the wiper blade assembly to couple the windshield wiper arm to the retainer.

Abstract
An improved structure of windshield wiper includes a wiper blade assembly, a retainer, and a plurality of adaptors that is selectively and exchangeably mountable to the retainer. The retainer forms a mounting hole in a top of a front end portion and has a mounting bar rearward of the mounting hole and has a rear end portion forming a lower step section, which includes an engagement slot and an engagement rib respectively formed in front and rear sections of each side face thereof The adaptors are of different structures. The retainer is coupled to the wiper blade assembly, or alternatively, the adaptors are selectively attached to the retainer, so that windshield wiper arms of different styles may selectively fit to the retainer or the adaptors to thereby expand the applicability of the windshield wiper blade.

6. A structure of windshield wiper, comprising:
-
a wiper blade assembly, which has a central portion forming a positioning section, the positioning section comprising a coupling bar fixed at a central portion thereof; a retainer, which is in an elongate configuration having a front end portion forming a curved shape, the retainer forming a mounting hole in a top of the front end portion and a notch rearward of the mounting hole, the notch comprising a mounting bar fixed therein, the retainer having a rear end portion forming a lower step section, on which vertical positioning tabs are formed, the lower step comprising an engagement slot and an engagement rib respectively formed in front and rear sections of each side face of the lower step section, the lower step section having a bottom forming a coupling section, the coupling section being attachable to the coupling bar of the positioning section of the wiper blade assembly; and a second adaptor, which has a front end forming a mounting groove and a rear portion forming symmetrically arranged wings, the wings each having an inside surface forming an engagement rib, whereby the mounting groove of the second adaptor is engageable with the mounting bar of the retainer, and further pressing downward causes the engagement ribs on the inside surfaces of the wings to fit to and engage the engagement slots of the retainer so as to fix the second adaptor to the retainer and allow a windshield wiper arm of a different style to be fit to the second adaptor. - View Dependent Claims (7, 8)
