Abstract

A windshield wiper clip assembly for mounting a windshield wiper on to a wiper arm of shepherds crook configuration comprises a body of U-shape side cross-section which is closely embraced by the crook-shaped end, with outwardly-extending side walls forming a groove in which the arm lies. The side walls have facing projections which are spread apart when the arm is pressed into the groove and spring back behind it to retain it on the body, the projections having cam-faces inclined to facilitate this spreading apart. The assembly may be mounted on the wiper backing member by a saddle-shaped portion having bores which engage cooperating pivot pins on the backing member.

Claims

1. A windshield wiper clip assembly for the detachable attachment of a wiper to a wiper arm, wherein the arm has a wiper-engaging end of U-shaped shepherds crook configuration having the tip thereof turned back upon itself to extend parallel to the major part of the arm with an intervening rounded portion, the clip assembly comprising a body adapted for retaining engagement with a wiper superstructure backing member embraced by the said wiper-engAging arm end, the body being of U-shaped cross-section at the part thereof embraced by the arm to fit within the U-shaped arm end and having parallel side walls on either side of the U-shaped cross-section body part, the side walls forming between themselves a groove in which the arm end is engaged and held against transverse movement, and resilient armretaining means on the body comprising a pair of projections extending toward one another from the said side walls adjacent the base of the U-shaped portion of the body part embraced by the arm end, the projections being movable apart away from each other against the resilience of the material of the body upon insertion of the arm end between the projections, the projections being spaced from the said base of the U-shaped portion to engage behind the U-shaped arm end when the latter is embracing the said body part to retain the arm thereon.

2. The invention as claimed in claim 1, wherein each of the said pair of projections is provided with a respective cam face inclined in the direction of movement of the arm end when mounting the arm end on the assembly body part so as to facilitate the moving apart of the projections.

3. The invention as claimed in claim 1, wherein means adapting the body for retaining engagement on the windshield wiper backing member comprises an integral saddle-shaped portion thereof having parallel arms spaced to closely embrace the backing member, the arm having registering bores engageable on corresponding transversely projecting pins of the backing member to form a pivoted connection of the assembly to the backing member.
