Abstract

A windshield wiper blade connector may be used in connecting a windshield wiper blade to pin-type and hookslot wiper arms. The connector includes a side wall that defines a hole sized to receive a pin of a pin-type wiper arm. A movable beam is positioned relative to the hole in the side wall so that the beam engages the pin of the pin-type wiper arm when the pin is received in the hole to secure the connector to the pin-type wiper arm. A tab extends from the movable beam and is positioned so that the tab engages a slot of a hookslot wiper arm when the hookslot wiper arm is attached to the connector to secure the connector to the hookslot wiper arm.

Claims

1. A windshield wiper blade connector for use in connecting a windshield wiper blade to pin-type and hookslot wiper arms, the connector comprising:

structure for use in attaching the connector to a windshield wiper blade;

a side wall defining a hole sized to receive a pin of a pin-type wiper arm;

a movable beam positioned relative to the hole in the side wall so that the beam engages the pin of the pin-type wiper arm when the pin is received in the hole to secure the connector to the pin-type wiper arm;

a tab extending from the movable beam and positioned so that the tab engages a slot of a hookslot wiper arm when the hookslot wiper arm is attached to the connector to secure the connector to the hookslot wiper arm;

wherein the tab is located on a first side of the movable beam and the movable beam is positioned so that a second side of the movable beam engages the pin of the pin-type wiper arm when the connector is attached to the pin-type wiper arm and the structure for use in attaching the connector to a windshield wiper blade assembly includes a snap-fit latch.

2. The connector of claim 1, further comprising a second side wall defining a second hole sized to receive the pin of the pin-type wiper arm.

3. The connector of claim 2, further comprising an upper wall extending between the first and second side walls.

4. The connector of claim 3, wherein the side walls extend above the upper wall to define a channel along the top of the connector, the channel securing a portion of a hookslot wiper arm when the connector is attached to the hookslot wiper arm.

5. The connector of claim 1, wherein the movable beam is isolated from direct connection to the side wall.

6. The connector of claim 1, wherein the tab includes a ramped end positioned to encounter an end of the hookslot arm as the connector is attached to the hookslot arm.

7. A The connector of claim 1, wherein the movable beam and the tab are configured so that the beam may be depressed to bend the beam and retract the tab from the slot of the hookslot wiper arm to release the connector from the hookslot wiper arm.

8. The connector of claim 7, further comprising a button for use in bending the movable beam.

9. The connector of claim 8, wherein the button comprises a textured button.

10. The connector of claim 1, wherein the movable beam is positioned relative to the hole so that the beam partially blocks a path extending from the hole.

11. The connector of claim 1, wherein a width of the movable beam is sized so that the beam fits within a groove in the pin of the pin-type wiper arm.

12. The connector of claim 1, wherein the movable beam comprises a cantilevered beam.

13. A windshield wiper blade assembly including the connector of claim 1, the assembly further comprising:

a windshield wiper blade carrier attached to the connector; and

a windshield wiper blade attached to the windshield wiper blade carrier.

14. The connector of claim 1, wherein the hole sized to receive the pin of the pin-type wiper arm is enclosed such that the side wall completely surrounds the hole.

15. The connector of claim 1, wherein the structure for attaching the connector to the windshield wiper blade is independent of the hole sized to receive the pin of the pin-type wiper arm.

16. The connector of claim 1, wherein the hole sized to receive the pin of the pin-type wiper arm permits attachment to the pin when the connector is attached to the windshield wiper blade.

17. A multi-purpose windshield wiper blade connector for use in connecting a windshield wiper blade to pin-type and hookslot wiper arms, the connector comprising:

structure for use in attaching the connector to a windshield wiper blade;

a pair of side walls, each side wall defining a hole sized to receive a pin of a pin-type wiper arm;

an upper wall positioned between the two side walls;

a cantilevered beam positioned relative to the holes in the side walls so that the beam engages the pin of the pin-type wiper arm when the pin is received in the holes to secure the connector to the pin-type wiper arm; and

a tab extending from the cantilevered beam and positioned so that the tab engages a slot of a hookslot wiper arm when the hookslot wiper arm is attached to the connector to secure the connector to the hookslot wiper arm;

wherein

the side walls extend above the upper wall to define a channel along the top of the connector, the channel securing a portion of a hookslot wiper arm when the connector is attached to the hookslot wiper arm,

the tab is located on a first side of the cantilevered beam and the cantilevered beam is positioned so that a second side of the cantilevered beam engages the pin of the pin-type wiper arm when the connector is attached to the pin-type wiper arms, and

the structure for use in attaching the connector to a windshield wiper blade comprises a snap-fit latch for use in attaching the connector to a windshield wiper blade.

18. The connector of claim 17, wherein the tab includes a ramped end positioned to encounter an end of the hookslot arm as the connector is attached to the hookslot arm.

19. The connector of claim 17, wherein the cantilevered beam and the tab are configured so that the beam may be depressed to bend the beam and retract the tab from the slot of the hookslot wiper arm to release the connector from the hookslot wiper arm.

20. The connector of claim 17, wherein the cantilevered beam is positioned relative to the holes so that the beam partially blocks a path extending between the holes.

21. The connector of claim 17, wherein a width of the cantilevered beam is sized so that the beam fits within a groove in the pin of the pin-type wiper arm.

22. A windshield wiper blade assembly including the connector of claim 17, the assembly further comprising:

a windshield wiper blade carrier attached to the connector; and

a windshield wiper blade attached to the windshield wiper blade carrier.

23. The connector of claim 17, wherein the side walls completely surround the holes sized to receive the pin of the pin-type wiper arm.

24. The connector of claim 17, wherein the structure for attaching the connector to the windshield wiper blade is independent of the holes for receiving the pin of the pin-type wiper arm.

25. The connector of claim 17, wherein the holes sized to receive the pin of the pin-type wiper arm permit attachment to the pin when the connector is attached to the windshield wiper blade.

26. A windshield wiper blade connector comprising:

a pin support having a support axis and a mechanism to secure the connector to a pin of a pin-type wiper arm with a longitudinal axis of the pin in line with the support axis and the pin restrained against axial motion,

structure for use in attaching the connector to a windshield wiper blade, and

a hook support having a mechanism to secure a hook of a hookslot wiper arm against longitudinal motion with the pin support axis being perpendicular to the length of the hookslot wiper arm and in a space defined within the hooks,

wherein the structure for use in attaching the connector to a windshield wiper blade comprises a snap-fit latch for use in attaching the connector to a windshield wiper blade.

27. The connector of claim 26, wherein the structure for attaching the connector to the windshield wiper blade is independent of the mechanism to secure the connector to a pin of a pin-type wiper arm.

28. A windshield wiper blade connector comprising:

a mechanism configured to secure the connector to a either a pin-type wiper arm or a hookslot wiper arm,

a tab that is movable between one position in which the connector may be mounted on a pin-type wiper arm and a second position in which the connector may be mounted on a hookslot wiper arm, and

a snap-fit latch for use in attaching the connector to a windshield wiper blade.
