Abstract

A connector for connecting a wiper blade and multiple types of wiper arms, the connector including a base for attachment to a wiper blade. The connector further includes a receiving element attached to the base, the receiving element having a structure to receive and be connected to at least six different wiper arms.

First claim

We claim:

1. A connector for connecting a wiper blade and a wiper arm, the connector comprising:
a base for attachment to said wiper blade;
a receiving element pivotably and directly attached to said base, wherein said receiving element is arranged above said base as viewed along a vertical direction, said receiving element comprising:
an attachment that pivotably couples said receiving element to said base;
a recess structured to receive a first wiper arm;
a pivot stop that is positioned adjacent to said recess, wherein when said first wiper arm is received by said recess, said pivot stop engages said first wiper arm and prevents said receiving element from pivoting relative to said base;
a support surface comprising a pair of flexible wing stops that face one another and can be pressed towards one another;
an engagement surface spaced from and facing said support surface as viewed along said vertical direction, wherein said engagement surface is substantially parallel to said support surface along an entire length of said engagement surface, said engagement surface and said support surface define a slot therebetween that is dimensioned to snugly receive a surface of a second wiper arm, and wherein said slot extends along a length of said engagement surface as viewed along a horizontal direction that is perpendicular to said vertical direction, and said support surface and said engagement surface define a side opening that is unencumbered by any portion of said receiving element when a first axis, which has no end points and is parallel to a lateral direction that is perpendicular to both said vertical direction and said horizontal direction, passes through said side opening and does not intersect said receiving element in any way, wherein said engagement surface comprises:
a first side support;
a second side support that faces said first side support; and
an engagement tongue, wherein one end of said engagement tongue is attached to both said first side support and said second side support and an opposite end of said engagement tongue is unattached and has a protrusion that faces said support surface; and

wherein a rear opening of said slot is defined by said first side support, said second side support and said support surface and wherein said rear opening is perpendicularly intersected by a second axis that is perpendicular to and intersects said first axis and extends towards said rear opening without intersecting said receiving element in any way.

2. The connector of claim 1 , wherein said first side support and said second side support move independently of said engagement tongue and vice versa.

3. The connector of claim 1 , wherein said engagement tongue comprises a release notch that is located on a side opposite of said protrusion.

4. The connector of claim 1 , wherein said pair of flexible wing stops can be pressed towards one another along a direction that is perpendicular to a longitudinal axis of said slot.

5. The connector of claim 1 , wherein said pivot stop is integral with said base.

6. The connector of claim 1 , wherein said receiving element has a structure to receive and be connected to at least six different wiper arms.

7. The connector of claim 6 , wherein said at least six different wiper arms are an I & L wiper arm, a PTB wiper arm, a first pin wiper arm, a second pin wiper arm, a first J-hook wiper arm and a second J-hook wiper arm.

8. The connector of claim 6 , wherein said at least six different wiper arms comprise at least three different classes of wiper arms.

9. The connector of claim 1 , wherein said receiving element comprises a cap that has an indent, wherein said cap pivots from an open position to a closed position, wherein at said closed position, said indent engages said wiper arm received by said recess.

10. The connector of claim 1 , wherein said receiving element comprises a second recess to receive a wiper al iii and wherein said receiving element comprises a cap that has a pair of indents, wherein said cap pivots from an open position to a closed position, wherein at said closed position, said indent engages said wiper arm received by either said recess or said second recess.

11. A windshield wiper comprising:
a wiper blade;
a wiper arm;
a connector attached to said wiper arm comprising:
a base attached to said wiper blade;

a receiving element pivotably and directly attached to said base, wherein said receiving element is arranged above said base as viewed along a vertical direction, said receiving element comprising:
an attachment that pivotably couples said receiving element to said base;
a recess structured to receive a first wiper arm;
a pivot stop that is positioned adjacent to said recess, wherein when said first wiper arm is received by said recess, said pivot stop engages said first wiper arm and prevents said receiving element from pivoting relative to said base;
a support surface comprising a pair of flexible wing stops that face one another and can be pressed towards one another;
an engagement surface spaced from and facing said support surface as viewed along said vertical direction, wherein said engagement surface is substantially parallel to said support surface along an entire length of said engagement surface, said engagement surface and said support surface define a slot therebetween that is dimensioned to snugly receive a surface of a second wiper arm, and wherein said slot extends along a length of said engagement surface as viewed along a horizontal direction that is perpendicular to said vertical direction, and said support surface and said engagement surface define a side opening that is unencumbered by any portion of said receiving element when a first axis, which has no end points and is parallel to a lateral direction that is perpendicular to both said vertical direction and said horizontal direction, passes through said side opening and does not intersect said receiving element in any way, wherein said engagement surface comprises:
a first side support;
a second side support that faces said first side support; and
an engagement tongue, wherein one end of said engagement tongue is attached to both said first side support and said second side support and an opposite end of said engagement tongue is unattached and has a protrusion that faces said support surface; and

wherein a rear opening of said slot is defined by said first side support, said second side support and said support surface and wherein said rear opening is perpendicularly intersected by a second axis that is perpendicular to and intersects said first axis and extends towards said rear opening without intersecting said receiving element in any way.

12. The windshield wiper of claim 11 , wherein said first side support and said second side support move independently of said engagement tongue and vice versa.

13. The windshield wiper of claim 11 , wherein said engagement tongue comprises a release notch that is located on a side opposite of said protrusion.

14. The windshield wiper of claim 11 , wherein said pair of flexible wing stops can be pressed towards one another along a direction that is perpendicular to a longitudinal axis of said slot.

15. The windshield wiper of claim 11 , wherein said pivot stop is integral with said base.

16. The windshield wiper of claim 11 , wherein said receiving element has a structure to receive and be connected to at least six different wiper arms.

17. The windshield wiper of claim 16 , wherein said at least six different wiper arms are an I & L wiper arm, a PTB wiper arm, a first pin wip
