  • Publication number: 20120054976
    Abstract: A connecting assembly (10) for a windshield wiper (10) includes a fixing member (11) and a supporting arm (12). The connecting assembly (20) includes a pivoting base (21) and a cover cap (22). The pivoting base (21) comprises an engaging portion (211) , a first insertion portion (212) and a second insertion portion (213) extending from the engaging portion (211) in opposite directions. The engaging portion (211) is engaged with the fixing member (11). The first insertion portion (212) and the second insertion portion (213) are symmetrical to each other with respect to the engaging portion (211). The cover cap (22) is assembled with the supporting arm (12) and put outside the first insertion portion (212) and the second insertion portion (213) in dual directions. Since the first insertion portion (212) and the second insertion portion (213) are configured to be symmetrical to each other, the supporting arm (12) can be firmly connected to the windshield wiper (10) with a changeable connecting direction.

  • Patent number: 7827652
    Abstract: A windscreen wiper structure includes a supporting object, a windscreen wiper strip, and a connecting device. The windscreen wiper strip fixes to the supporting object's lower surface. The connecting device includes a center stand, a hook stand, an outer housing, and a lid body. The center stand fixes in the middle of the supporting object's upper surface. The center stand has an axle. The hook stand has a pivoting hole. The hook stand's pivoting hole connects to the axle. The outer housing disposes in the center stand's exterior. There is an opening hole in the outer housing's upper part. A piercing hole sets in the lid body's upper part. One end of the lid body pivotally connects to the outer housing. The lid body opens or closes with the outer housing's opening hole. Hence, the connecting device and the windscreen wiper strip joins together quickly, making assembly and disassembly easier.

  • Publication number: 20100236008
    Abstract: A windshield wiper includes a flexible support with fasteners and positioning holes, a connecting piece fixedly connected to the flexible support, a warping piece that has a positioning portion which extends to form an elastic portion with locking pieces, a positioning piece, and a windshield wiper blade with the fasteners fastened to its two ends. The middle portion and the end portion of the flexible support have different curvatures. The positioning portion has a through-hole and abuts the flexible support. The positioning piece passes through the through-hole and the positioning hole to be fastened to the flexible support. The locking piece is fastened to the windshield wiper blade. Therefore, the windshield wiper blade is prevented from shaking due to an external force, by being attached to the windshield tightly through the warping piece and the positioning piece. Thus, its effect of wiping away rain is increased.
