Abstract
Abstract A windshield wiper blade assembly comprises a yoke member which has a projecting spherical blade engagement member which presents an enlarged intermediate portion or ball member which is adapted to engage into a ball-shaped recess by entry through a top surface slot on an intermediate yoke member. The intermediate yoke member is formed with a slot extending downwardly from the intermediate enlarged portion of the receiving recess to the bottom of the member to permit flexure of both ends of the member to close the slot at the bottom and to open the slot at the top to permit access of the blade engagement member of the yoke. The intermediate member is made of triangular cross-section and the slot for receiving the blade engagement member of the yoke member is of vertical triangular configuration with the apex of the triangle located adjacent the slot at the bottom of the intermediate yoke member. The triangular configuration extends on each side of the spherical receiving recess for the ball member of the yoke.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
224 words
A windshield wiper blade assembly comprising a main yoke member for operatively holding a wiper blade having a projecting engagement member thereon with an enlarged intermediate portion, a second member adapted to be carried by said yoke member having a top surface with a receiving recess defined therein with an enlarged intermediate portion of a size to accommodate the enlarged portion of said engagement member, the recess including a top access slot on said top surface which is smaller than the width of the maximum dimension of said enlarged portion so as to permit forced entry of said enlarged portion of said engagement member, and a bottom slot defined in said second member extending from the bottom of said enlarged intermediate portion of said recess to the bottom of said second member and permitting flexure of said second member on each side of the bottom slot in directions toward the bottom of said second member to open the top access slot so as to receive the engagement member, said second member including an intermediate wall portion bounding each end of Said receiving recess intermediate portion and a generally triangular slot on each side of the intermediate wall portion with a base of the triangular slot facing the main yoke member and the apices of said slots facing the bottom slot of said second member.
Claim 2
Dependent Claim
224 words
