Abstract

A wiper blade having a wiper strip, a primary frame and a pair of secondary frames. The primary frame may have a top side and opposite ends, a connection device capable of connecting the wiper blade to a wiper arm disposed on the top side of the primary frame, and a connection structure disposed on each of the opposite ends of the primary frame. Each secondary frame may have a central pivot connection portion and two leg portions extending from the central pivot connection portion, a pivot structure disposed on the central pivot connection portion of the secondary frames. The pivot structure may be a turn-buckle holder comprising two holder halves and a rivet wherein the rivet passes through the two holder halves and holds them together.

Claims

1. A wiper blade comprising:

a wiper strip,

a primary frame, having a top side and opposite ends, a connection device capable of connecting the wiper blade to a wiper arm disposed on the top side of the primary frame, and a connection structure disposed on each of the opposite ends of the primary frame;

a pair of secondary frames, each having a central pivot connection portion and two leg portions extending from the central pivot connection portion, a pivot structure disposed on the central pivot connection portion of the secondary frames;

wherein the pivot structure comprises is a turn-buckle holder comprising two holder halves and a rivet wherein the rivet passes through the two holder halves and holds them together.

2. The wiper blade for claim 1 wherein the holder halves further comprise a channel that receives the central pivot connection portion of the respective secondary frame.

3. The wiper blade of claim 2 wherein the central pivot connection portion of the secondary frames is provided with recesses and the holder halves are provided with projections which fit into the recesses in the central pivot connection portion of the secondary frames.

4. The wiper blade of claim 1 wherein the connection structure on the ends of the primary frame comprises pivot extension walls.

5. The wiper blade of claim 1 wherein the secondary frames have a generally thin structure.

6. The wiper blade of claim 5 wherein the secondary frames are a pair of beams.

7. The wiper blade of claim 5 wherein the secondary frames are a pair of brackets.

8. The wiper blade of claim 1 wherein the legs of the secondary frames are symmetrical

9. The wiper blade of claim 1 wherein one of the two leg portions of a first beam of the pair of beams is longer than the other leg portion of the first beam of the pair of beams.

10. The wiper blade of claim 1 wherein at least one leg portion of at least one of the secondary frames is provided with a wiper strip holder capable of securing the wiper strip.

11. The wiper blade of claim 1 wherein a pair of tertiary frames connect to each of the secondary frames, and the tertiary frames secure the wiper strip.

12. The wiper blade of claim 1 further comprising at least one tertiary frame, wherein at least one leg portion of at least one of the secondary frames is provided with a tertiary frame connection structure, and wherein the at least one tertiary frame is connected to the tertiary frame connection structure of the least one of the secondary frames.

13. The wiper blade of claim 12 wherein the tertiary frame is symmetric.

14. The wiper blade of claim 12 wherein the tertiary frame has two legs descending from a middle portion and one of the two legs is longer than the other.

20. The wiper blade of claim 1 wherein a pair of tertiary frames connect to each of the secondary frames, and the tertiary frames secure the wiper strip.

15. A hinge for a wiper blade capable of connecting a parent frame to a child frame comprising:

a turn-buckle holder comprising two holder halves and a rivet, wherein the rivet passes through the two holder halves and holds them together.

16. A wiper blade comprising:

a wiper strip,

a primary frame, having a top side and opposite ends, a connection device capable of connecting the wiper blade to a wiper arm disposed on the top side of the primary frame, and a connection structure disposed on each of the opposite ends of the primary frame;

a pair of secondary frames, each having a central pivot connection portion and two leg portions extending from the central pivot connection portion, a pivot structure disposed on the central pivot connection portion of the secondary frames;

wherein the pivot structure comprises a turn-buckle holder comprising a unitary structure.

17. The wiper blade of claim 16 wherein the central pivot connection portion of the secondary frames is provided with recesses and the turn-buckle holder is provided with projections which fit into the recesses in the central pivot connection portion of the secondary frames.

18. The wiper blade of claim 16 wherein the connection structure on the ends of the primary frame comprises pivot extension walls.

19. The wiper blade of claim 16 wherein the secondary frames have a generally thin structure.
