Abstract
Abstract In a device for attaching a windshield wiper arm to a drive shaft, a receiving member having a socket-shaped first section is fitted over the drive shaft and a cover member and a coupling member are pivotally attached on a common pivot axis to a second section of the receiving member which extends laterally from its first section. The coupling member extends from the second section away from the first section and is arranged to be secured to the wiper arm. The cover member can be pivoted between a closed position covering the first section in which the drive shaft is secured and an open position in which the drive shaft is accessible. The cover member and coupling member are positioned so that they can be pivoted relative to one another as well as relative to the receiving member.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
267 words
A device for mounting a windshield wiper arm, particularly for use on motor vehicles, on a drive shaft, comprising a receiving member having a first section forming a socket therein arranged to fit over the drive shaft, said first section having an opening therethrough communicating with the socket and arranged to engage the drive shaft securely therein, and a cover member arranged to fit over said receiving member, said receiving member including a second section extending laterally from said first section transversely of the axis of the opening in said first section, a coupling member securing the wiper arm to said receiving member shaft means having an axis about which said cover member and said coupling member are pivoted, said second section having a bore extending therethrough between its side surfaces transversely of the axis of the opening in said first section, said shaft means being disposed in the bore in said second section and extending laterally outwardly from said second section, said cover member and said coupling member having side walls positioned outwardly from the sides of said second section and said side walls of said cover member and coupling member having openings aligned with the bore through said second section for receiving said shaft means, said side walls of said cover member being rotatably mounted between said second section of said receiving member and said side walls of said coupling member, and washer means interposed between said shaft means and said openings in said cover member whereby said cover member is rotatable on said washer means and the latter is rotatable on said shaft means.
Claim 2
Independent Claim
267 words
A device for mounting a windshield wiper arm, particularly for use on motor vehicles, on a drive shaft, comprising a receiving member having a first section forming a socket therein arranged to fit over the drive shaft, said first section having an opening therethrough communicating with the socket and arranged to engage the drive shaft securely therein, and a cover member arranged to fit over said receiving member, said receiving member including a second section extending laterally from said first section transversely of the axis of the opening in said first section, a coupling member securing the wiper arm to said receiving member shaft means having an axis about which said cover member and said coupling member are pivoted, said second section having a bore extending therethrough between its side surfaces transversely of the axis of the opening in said first section, said shaft means being disposed in the bore in said second section and extending laterally outwardly from said second section, said cover member and said coupling member having side walls positioned outwardly from the sides of said second section and said side walls of said cover member and coupling member having openings aligned with the bore through said second section for receiving said shaft means, said side walls of said cover member being rotatably mounted between said second section of said receiving member and said side walls of said coupling member, and washer means interposed between said shaft means and said openings in said cover member whereby said cover member is rotatable on said washer means and the latter is rotatable on said shaft means.
Claim 3
Dependent Claim
32 words
A device as set forth in claim 1 wherein said receiving member and said cover member are provided with cooperable stop means for detachably locking said cover member in a closed position.
Claim 4
Dependent Claim
98 words
A device as set forth in claim 1, wherein said cover member is pivotal between a closed position covering the opening in said first section of said receiving member and an open position affording access to the opening in said first section, the end of said cover member above said second section being bent downwardly toward the pivot axis in said second section, said coupling member terminating above the downwardly bent end of said cover member at a position spaced outwardly from the pivot axis in said second section on the opposite side thereof from said first section.
Claim 5
Dependent Claim
151 words
A device, as set forth in claim 3, wherein a pin is secured to said second section between said first section and the bore in said second section, a yoke rotatably secured on said pin and extending outwardly away from said first section, a spring secured to the end of said yoke spaced from said spring, and the opposite end of said spring arranged to be secured to the wiper arm, said second section forming guide elements for directing said yoke as it pivots with said coupling member and the wiper arm, and said guide elements forming recesses for receiving the downwardly bent end of said cover member as it moves from a closed position covering the said first section of said receiving member to an open position affording access to the opening in said first section with the downwardly bend end moving toward said second section of said receiving member.
