Abstract

The instant disclosure provides a wiper, comprising a wiper connector, a flexible member, a reinforcing member, a rigid frame, a plurality of fastening members and a wiper blade. The flexible member includes a central loading portion and two distal loading portion extending symmetrically from two ends of the central loading portion, where the central loading portion has a zero curvature. The reinforcing member is sleevingly coupled to the flexible member. A front-facing side of the reinforcing member has at least one wind-deflecting rib formed thereon. The rigid frame is arranged on the central loading portion to connect the wiper connector. The fastening member is engaged to the second loading portion. The wiper blade is inserted through the plurality of fastening members. Thus, a better conformity can be achieved between the windshield and the wiper through the wind pressure while driving to provide a better water removal effect.

Claims

1. A windshield wiper, comprising:

a wiper connector;

a flexible member including a generally elongated central loading portion and two distal loading portions extending substantially symmetrically from two ends of the central loading portion, wherein the central loading portion has a zero curvature;

a reinforcing member sleevingly coupled to the flexible member, wherein a front-facing side thereof has at least one wind-deflecting rib arranged thereon;

a rigid frame arranged on the central loading portion of the flexible member for connecting the wiper connector;

at least one fastening member connected to each of the second loading members; and

a wiper blade fixed to the fastening member.

2. The wiper according to claim 1, wherein the curvature of the second loading portion is greater than that of the central loading portion.

3. The wiper according to claim 1, wherein the fastening member has a support, a long plate and two side plates, wherein the support extends upwardly and is connected to the long plate, and wherein the two side plates extends downwardly from the support, the distal ends of the two side plates has a hook portion which bends inwardly.

4. The wiper according to claim 3, wherein the second loading portion has a plurality of long fastening holes formed thereon, wherein the long plate inserts through the plurality of long fastening holes for the fastening member to engage rotatably to the second loading portion.

5. The wiper according to claim 1, further comprising two engaging members, wherein each of the engaging members has two first hooks which extend upwardly and two second hooks which extend downwardly.

6. The wiper according to claim 5, wherein two engaging holes are formed on the other distal ends of the two loading portions, away from the central loading portion, wherein the two first hooks are engaged to the two engaging holes, and the wiper blade is fixed by the two second hooks.

7. The wiper according to claim 1, wherein the center of the reinforcing member has an opening portion formed therein for the rigid frame to expose therefrom for connection to the wiper connector.

8. A windshield wiper, comprising:

a wiper connector;

a flexible member including a generally elongated central loading portion and two distal loading portions extending substantially symmetrically from two ends of the central loading portion, wherein the central loading portion has a zero curvature;

a reinforcing member sleevingly coupled to the flexible member, wherein a front-facing side thereof has at least one wind-deflecting rib arranged thereon;

a rigid frame arranged on the central loading portion to connect the wiper connector;

at least one fastening member engaged to the flexible member;

at least one pressing member including a positioning portion, two hard arms, and a pair of coupling portions arranged on the respective distal ends of the hard arms, wherein the positioning portion is engaged to the fastening member; and

a wiper blade fixed to the coupling portion.

9. The wiper according to claim 8, wherein the curvature of the second loading portion is greater than that of the central loading portion.

10. The wiper according to claim 8, wherein the fastening member has a support, a long plate and two side plates, wherein the support extends downwardly and is connected to the long plate, and wherein the two side plates extends upwardly from the support, the distal ends of the two side plates has a hook portion which bends inwardly.

11. The wiper according to claim 8, wherein the middle section of the reinforcing member has at least one latch formed thereon, wherein the latch is connected between the two side walls of the reinforcing member, and wherein the latch is arranged between the upper trough of the wiper connector and the lower trough of the rigid frame.

12. The wiper according to claim 10, wherein the second loading portion has a plurality of indentations formed thereon for the coupling portion to engage to the second loading portion.

13. The wiper according to claim 10, wherein the positioning portion has a long positioning hole formed thereon, wherein the long plate is inserted through the long positioning hole, the two ends of the long plate abut against the positioning portion for the fastening member to rotatably engage to the hard plate.

14. The wiper according to claim 8, further comprising two engaging members, the other distal ends of the two distal loading portion have two engaging holes, away from the central loading portion, formed thereon to fix the two engaging members.

15. The wiper according to claim 14, wherein each of the two engaging members includes two first hooks extending upwardly and two second hooks extending downwardly, and wherein the two first hooks are coupled to the two engaging holes, and the wiper blade is fixed by the two second hooks.
