Wiper coupler adapter and wiper assembly incorporating same
View Patent ↗A wiper coupler adaptor for use in releasably attaching a wiper assembly to a bayonet style wiper arm having an attachment end includes a pair of sidewalls each including a post that extends transversely toward the other to operatively engage structure of a wiper assembly and a deck disposed between the sidewalls that cooperates with a portion of the sidewalls to define a rest adapted to operatively receive the attachment end of the wiper arm. The sidewalls each include a ledge that extends transversely toward the other to operatively engage the attachment end of the wiper arm. The wiper coupler adaptor also includes a locking mechanism including a cantilevered body and a head disposed at a terminal end of the cantilevered body. The head includes a lip depending therefrom that is adapted to extend through an aperture in the base of the attachment end and receive a portion of the base of the attachment end to prevent undesired release of the wiper coupler adaptor from the attachment end of the wiper arm.
1. A wiper coupler adaptor for use in releasably attaching a wiper assembly to a bayonet style wiper arm having an attachment end, said wiper coupler adaptor comprising:
a pair of sidewalls each including a post that extends transversely toward the other to operatively engage the wiper assembly;
a deck disposed between said sidewalls that cooperates with a portion of said sidewalls to define a rest adapted to operatively receive the attachment end of the wiper arm;
said sidewalls each including a ledge that extends from each of said sidewalls transversely toward the other to operatively engage the attachment end of the wiper arm; and
a locking mechanism including a cantilevered body and a head disposed at a terminal end of said cantilevered body, said head including a lip extending therefrom that is adapted to extend through an aperture of the attachment end and overlap a portion of the attachment end to prevent undesired release of said wiper coupler adaptor from the attachment end of the wiper arm, said locking mechanism further including a cantilevered member extending downwardly and outwardly rearwardly from said head to provide a biasing force to bias the lip forward to overlap a portion of the attachment member when said cantilevered member is disposed in the aperture.
2. A wiper coupler adaptor as set forth in claim 1 wherein said lip extends longitudinally forward from said head.
3. A wiper coupler adaptor as set forth in claim 1 wherein said head and said cantilevered body form a generally “T” shaped member.
4. A wiper coupler adaptor as set forth in claim 1 wherein said ledge is disposed forward of said locking mechanism.
5. A wiper coupler adaptor as set forth in claim 1 wherein said ledge extends longitudinally a predetermined distance.
6. A wiper coupler adaptor as set forth in claim 1 wherein said ledge is disposed below a height of said head.
7. A wiper coupler adaptor as set forth in claim 1 wherein said deck is disposed below a height of said sidewalls to form a recess for the attachment end.
8. A wiper coupler adaptor as set forth in claim 1 wherein said sidewalls and said ledge are integral, unitary, and one-piece.
9. A wiper coupler adaptor as set forth in claim 1 wherein said cantilevered body, said head, and said deck are integral, unitary, and one-piece.
10. A wiper assembly for use in connection with a bayonet style wiper arm, said wiper assembly comprising:
a wiping element adapted to contact a surface to be wiped;
a structure supporting said wiping element; and
a wiper coupler adaptor operatively mounted to said structure that is adapted to releasably attach to an attachment end of the wiper arm, said wiper coupler adaptor including a pair of sidewalls and a deck disposed therebetween that is adapted to operatively engage a portion of the attachment end of the wiper arm, said deck and a portion of said sidewalls cooperating to define a rest adapted to operatively receive the attachment end, said sidewalls each including a ledge that extends from each of said sidewalls transversely toward the other to operatively engage the attachment end of the wiper arm, and a locking mechanism including a cantilevered body and a head disposed at a terminal end of said cantilevered body, said head including a lip extending therefrom that is adapted to extend through an aperture in the attachment end and overlap a portion of the attachment end to prevent undesired release of said wiper coupler adaptor from the attachment end of the wiper arm, said locking mechanism further including a cantilevered member extending downwardly and outwardly rearwardly from said head to provide a biasing force to bias the lip forward to overlap a portion of the attachment member when said cantilevered member is disposed in the aperture.
11. A wiper assembly as set forth in claim 10 wherein said head extends longitudinally forward from said cantilevered body.
12. A wiper assembly as set forth in claim 10 wherein said head and said cantilevered body form a generally “T” shaped member.
13. A wiper assembly as set forth in claim 10 wherein said ledge is disposed forward of said locking mechanism.
14. A wiper assembly as set forth in claim 10 wherein said ledge extends longitudinally a predetermined distance.
15. A wiper assembly as set forth in claim 10 wherein said ledge is disposed below a height of said head.
16. A wiper assembly as set forth in claim 10 wherein said cantilevered body, said head, and said deck are integral, unitary, and one-piece.
17. A wiper assembly as set forth in claim 16 wherein said sidewalls and said ledge are integral, unitary, and one-piece.
18. A wiper assembly for use in connection with a bayonet style wiper arm, said wiper assembly comprising:
a wiping element adapted to contact a surface to be wiped;
a structure supporting said wiping element;
a wiper coupler adaptor operatively mounted to said structure that is adapted to releasably attach to an attachment end of the wiper arm, said wiper coupler adaptor including a pair of sidewalls and a deck disposed therebetween that is adapted to operatively engage a portion of the attachment end of the wiper arm, said deck and a portion of said sidewalls cooperating to define a rest adapted to operatively receive the attachment end, said sidewalls each including a ledge that extends from said sidewalls transversely toward the other to operatively engage the attachment end of the wiper arm, and a locking mechanism including a cantilevered body and a head disposed at a terminal end of said cantilevered body, said head extending longitudinally forward from said cantilevered body including a lip extending therefrom that is adapted to extend through an aperture in the attachment end and overlap a portion of the attachment end and a cantilevered member extending downwardly and outwardly from said head to prevent undesired release of said wiper coupler adaptor from the attachment end of the wiper arm, said locking mechanism further including a cantilevered member extending downwardly and outwardly rearwardly from said head to provide a biasing force to bias the lip forward to overlap a portion of the attachment member when said cantilevered member is disposed in the aperture; and
wherein said ledge is disposed forward of said locking mechanism and below a height of said head.
