Adapter for coupling windshield wiper blade holder with hooked wiper arm
First Claim
1. An adapter for connecting a wiper blade holder with a windshield wiper arm that terminates in a hook having a finger turned back along the arm, comprising a unitary molded body of resilient material forming two similarly shaped side panels and a front wall and a cross shaft which join together respective forward upper portions of said panels and hold the upper portions of said panels spaced apart to receive said hook between them, said panels having on lower portions thereof elements to mate with and to couple said body to coupling elements on a central portion of said blade holder, said front wall and said cross shaft being spaced apart longitudinally of said panels and disposed relative to said lower portions and to backward upper portions of said panels so that said body apart from the blade holder can be held in a posture in which the space between said shaft and said wall will be aligned with the finger of said hook, whereupon said finger can be passed through said space to engage said shaft pivotably in said hook, said lower portions and said backward upper portions of said panels having between them unobstructed space slightly wider than said hook and through which said hook when engaged with said shaft is free to turn upon an ensuing turning of said body about the axis of said shaft to a position for mating said coupling elements, whereby upon such turning said hook will be captured transversely by said shaft, longitudinally between said shaft and said front wall and laterally between the upper portions of said panels.

Abstract
An adapter for coupling a windshield wiper blade holder with a wiper arm of the type having a hooked end is provided as a unitary molded body of a resilient plastic material forming similarly shaped side panels held spaced apart and joined together by a front wall and a cross shaft which are so disposed relative to portions of the panels that the arm hook can be engaged onto the shaft when the body is turned away from a posture in which it can be coupled with the blade holder, and will be captured operably in the adapter when the body is turned back to that posture.

- 1. An adapter for connecting a wiper blade holder with a windshield wiper arm that terminates in a hook having a finger turned back along the arm, comprising a unitary molded body of resilient material forming two similarly shaped side panels and a front wall and a cross shaft which join together respective forward upper portions of said panels and hold the upper portions of said panels spaced apart to receive said hook between them, said panels having on lower portions thereof elements to mate with and to couple said body to coupling elements on a central portion of said blade holder, said front wall and said cross shaft being spaced apart longitudinally of said panels and disposed relative to said lower portions and to backward upper portions of said panels so that said body apart from the blade holder can be held in a posture in which the space between said shaft and said wall will be aligned with the finger of said hook, whereupon said finger can be passed through said space to engage said shaft pivotably in said hook, said lower portions and said backward upper portions of said panels having between them unobstructed space slightly wider than said hook and through which said hook when engaged with said shaft is free to turn upon an ensuing turning of said body about the axis of said shaft to a position for mating said coupling elements, whereby upon such turning said hook will be captured transversely by said shaft, longitudinally between said shaft and said front wall and laterally between the upper portions of said panels.
- 6. An adapter for connecting a wiper blade holder with a windshield wiper arm that terminates in a hook having a finger turned back along the arm, comprising a unitary molded body of resilient plastic material forming two similarly shaped side panels and a front wall and a cross shaft which join together respective forward upper portions of said panels and hold said panels spaced apart to receive said hook between them, said panels having lower portions thereof formed to straddle a central portion of said blade holder and having in said lower portions sockets formed to fit upon and thus couple said panels to posts protruding from opposite sides of said central portion, said cross shaft and said front wall being spaced apart longitudinally of said panels and disposed so that said body apart from the blade holder can be held in a posture in which the space between said shaft and said wall will be aligned with the finger of said hook, whereupon said finger can be passed through said space to engage said shaft pivotably in said hook, said lower portions and said backward upper portions of said panels having between them unobstructed space slightly wider than said hook and through which said hook when engaged with said shaft is free to turn upon an ensuing turning of said body about the axis of said shaft to a position for engagement of said sockets upon said posts, whereby upon such turning said hook will be captured transversely by said shaft, longitudinally between said shaft and said front wall and laterally between the upper portions of said panels, said backward upper portions of said panels extending to corner portions thereof at a height above said forward upper portions and, when disposed away from a wiper arm, being convergeable elastically by pressure of a person'"'"'s fingers with resultant divergence of said lower panel portions to aid engagement or disengagement of said sockets and posts, said panels each having along its inner side at a level spaced above the coupling elements thereon a downwardly facing ledge engagable against the upper surface of said central portion to limit pivotal movement of said body relative to the blade holder when the adapter is coupled onto the blade holder, said backward upward portions of said panels each having on its inner side along its backward edge an inwardly protruding elongate rib positioned to engage a side edge of the hooked end of said wiper arm.
