Abstract

A wiper connector arranged to a bolt-type wiper arm, comprising a sleeve tube, a fastening member and a tube body, wherein the sleeve tube has a tube body, a first and a second flange, where the first flange defines a receiving compartment therein; the fastening member has a circular ring body and a plurality of abutting portions, the fastening member is fixed within the receiving compartment of the sleeve tube, the bolt is inserted into the fastening member, the circumferential portion of the bolt is tightly engaged by the plurality of abutting portions; the base has a clutching trough, a first and a second restricting trough, where the first and the second flanges of the sleeve tube are received respectively in the first and the second restricting troughs, and the tube body is secured in the clutching trough. The instant disclosure further provides a bolt-stabilizing sleeve adaptor.

Claims

1. A wiper connector for adapting wiper blades onto a bolt-type wiper arm, comprising:

a sleeve tube having a tube body, a first flange, and a second flange respectively extending from the two ends of the tube body,

wherein the sleeve tube has a pivoting hole defined therein and,

wherein one end of the pivoting hole forms an opening that is accommodatable for the bolt of the wiper arm,

wherein the first flange defines a receiving compartment;

a fastening member having a circular ring body and a plurality of abutting portions inwardly protruding from the inner fringe of the circular ring body,

wherein the fastening member is fixed in the receiving compartment of the sleeve tube,

wherein the bolt is insertable into the fastening member via the pivoting hole,

wherein the circumferential portion of the bolt is tightly engaged by the plurality of abutting portions; and

a base having a clutching trough, a first restricting trough, and a second restricting trough connected to the two ends of the clutching trough,

wherein the first and the second flanges of the sleeve tube are respectively receivable in the first and the second restricting troughs,

wherein the tube body is receivable in the clutching trough,

wherein the tube body is engaged tightly within the clutching trough.

2. The wiper connector according to claim 1, wherein the outer diameters of the first and the second flanges are greater than the outer diameter of the tube body, and wherein the outer diameters of the first and the second flanges are different.

3. The wiper connector according to claim 1, wherein the pivoting hole is substantially a circular hole, wherein the other end of the pivoting hole is either a closed or opened hole.

4. The wiper connector according to claim 1, wherein the plurality of abutting portions extends in a slant manner towards the inserting direction of the bolt.

5. The wiper connector according to claim 1, wherein the circumferential portion of the circular ring body has an interfering portion formed thereon, wherein the interfering portion is mounted to the inner walls of the receiving compartment.

6. The wiper connector according to claim 1, wherein the distance between the inner fringe and the outer fringe of the fastening member 2 is smaller than 5 mm.

7. The wiper connector according to claim 1, wherein the bolt is selected from the group consisting of a cylinder, a triangular prism, a tetragonal prism, a hexagonal prism, a polygonal prism, and an irregular-shaped prism.

8. The wiper connector according to claim 1, wherein the base has at least one accommodating slot formed thereon.

9. The wiper connector according to claim 1, wherein the base has an anti-mismating portion, wherein the anti-mismating portion includes two protrusions protrudingly formed on the base, and the two protrusions are formed on the two sides of the clutching trough.

10. The wiper connector according to claim 9, wherein the wiper arm further has a shoulder portion, the distance between the two protrusions is smaller than the outer diameters of the first and the second flanges, and the width of the shoulder portion of the wiper arm.

11. The wiper connector according to claim 10, wherein distance from any edge of the anti-mismating portion to the center point of the sleeve tube is greater than or equal to the distance from the center of the bolt to the shoulder portion.

12. The wiper connector according to claim 10, wherein the width of the anti-mismating portion is greater than or equal to the distance from the edge of the bolt to the inner fringe of the shoulder portion.

13. A bolt-stabilizing sleeve adaptor for adapting a wiper connector onto a bolt-type wiper arm, comprising:

a sleeve tube having a tube body, a first flange, and a second flange respectively extending from the two ends of the tube body,

wherein the sleeve tube has a pivoting hole defined therein and,

wherein one end of the pivoting hole forms an opening,

wherein the first flange defines a receiving compartment;

a fastening member having a circular ring body and a plurality of abutting portions inwardly protruding from the inner fringe of the circular ring body,

wherein the fastening member is fixed in the receiving compartment of the sleeve tube,

wherein the bolt is insertable into the fastening member via the pivoting hole,

wherein the circumferential portion of the bolt is tightly engaged by the plurality of abutting portions.

14. The bolt-stabilizing sleeve adaptor according to claim 13, wherein the outer diameters of the first and the second flanges are greater than the outer diameter of the tube body, and wherein the outer diameters of the first and the second flanges are different.

15. The bolt-stabilizing sleeve adaptor according to claim 13, wherein the pivoting hole is substantially a circular hole, wherein the other end of the pivoting hole is either a closed or opened hole.

16. The bolt-stabilizing sleeve adaptor according to claim 13, wherein the plurality of abutting portions extends in a slant manner towards the inserting direction of the bolt.

17. The bolt-stabilizing sleeve adaptor according to claim 13, wherein the circumferential portion of the circular ring body has an interfering portion formed thereon, wherein the interfering portion is mounted to the inner walls of the receiving compartment.

18. The bolt-stabilizing sleeve adaptor according to claim 13, wherein the distance between the inner fringe and the outer fringe of the fastening member 2 is smaller than 5 mm.

19. The bolt-stabilizing sleeve adaptor according to claim 13, wherein the bolt is selected from the group consisting of a cylinder, a triangular prism, a tetragonal prism, a hexagonal prism, a polygonal prism, and an irregular-shaped prism.
