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. ## Claims ### Claim 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 structure of a 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 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 depending therefrom that is adapted to extend through, an aperture of the attachment end and receive a portion of the attachment end to prevent undesired release of said wiper coupler adaptor from the attachment end of the wiper arm. ### Claim 2 (depends on 1) A wiper coupler adaptor as set forth in claim 1 wherein said lip extends longitudinally forward from said head. ### Claim 3 (depends on 1) A wiper coupler adaptor as set forth in claim 1 wherein said head and said cantilevered body form a generally “T” shaped member. ### Claim 4 (depends on 1) A wiper coupler adaptor as set forth in claim 1 wherein said locking mechanism includes a cantilevered member extending downwardly and outwardly from said head. ### Claim 5 (depends on 1) A wiper coupler adaptor as set forth in claim 1 wherein said ledge is disposed forward of said locking mechanism. ### Claim 6 (depends on 1) A wiper coupler adaptor as set forth in claim 1 wherein said ledge extends longitudinally a predetermined distance. ### Claim 7 (depends on 1) A wiper coupler adaptor as set forth in claim 1 wherein said ledge is disposed below a height of said head. ### Claim 8 (depends on 1) A wiper coupler adaptor as set forth in claim 1 wherein said deck is disposed below a height of said sidewall to form a recess for the attachment end. ### Claim 9 (depends on 1) A wiper coupler adaptor as set forth in claim 1 wherein said sidewalls and said ledge are integral, unitary, and one-piece. ### Claim 10 (depends on 1) 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. ### Claim 11 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 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 depending therefrom that is adapted to extend through an aperture in the attachment end and receive a portion of the attachment end to prevent undesired release of said wiper coupler adaptor from the attachment end of the wiper arm. ### Claim 12 (depends on 11) A wiper assembly as set forth in claim 11 wherein said head extends longitudinally forward from said cantilevered body. ### Claim 13 (depends on 11) A wiper assembly as set forth in claim 11 wherein said head and said cantilevered body form a generally “T” shaped member. ### Claim 14 (depends on 11) A wiper assembly as set forth in claim 11 wherein said locking mechanism includes a cantilevered member extending downwardly and outwardly from said head. ### Claim 15 (depends on 11) A wiper assembly as set forth in claim 11 wherein said ledge is disposed forward of said locking mechanism. ### Claim 16 (depends on 11) A wiper assembly as set forth, in claim 11 wherein said ledge extends longitudinally a predetermined distance. ### Claim 17 (depends on 11) A wiper assembly as set forth in claim 11 wherein said ledge is disposed below a height of said head. ### Claim 18 (depends on 11) A wiper assembly as set forth in claim 11 wherein said cantilevered body, said head, and said deck are integral, unitary, and one-piece. ### Claim 19 (depends on 18) A wiper assembly as set forth in claim 18 wherein said sidewalls and said ledge are integral, unitary, and one-piece, ### Claim 20 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 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 depending 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; and wherein said ledge is disposed forward of said locking mechanism, and below a height of said head.
