Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
195 words
A windshield wiper clip assembly for the detachable attachment of a windshield wiper to a wiper arm, the assembly comprising a clip body, a bore in the body for the reception therein of a wiper arm pin upon which the clip body can pivot about a corresponding axis, the pin having an intermediate portion providing at least one corresponding radially-extending retaining shoulder, a slot in the clip body positioned to register with the said intermediate portion of a pin engaged in the bore, and a U-shaped retaining member mounted in the slot, the retaining member having one arm thereof engaged with at least one slot wall thereof, and being provided at its free end with a transversely extending point engaging a slot wall to oppose withdrawal of the retaining member from the slot, the retaining member having a portion of the other arm thereof protrudable into the bore for engagement with the said retaining shoulder to prevent axial movement of the pin out of the bore, and having another portion of the said other arm extending from the slot for engagement by an operator for disengagement of the retaining member from the said retaining shoulder.
Claim 2
Dependent Claim
195 words
A windshield wiper clip assembly for the detachable attachment of a windshield wiper to a wiper arm, the assembly comprising a clip body, a bore in the body for the reception therein of a wiper arm pin upon which the clip body can pivot about a corresponding axis, the pin having an intermediate portion providing at least one corresponding radially-extending retaining shoulder, a slot in the clip body positioned to register with the said intermediate portion of a pin engaged in the bore, and a U-shaped retaining member mounted in the slot, the retaining member having one arm thereof engaged with at least one slot wall thereof, and being provided at its free end with a transversely extending point engaging a slot wall to oppose withdrawal of the retaining member from the slot, the retaining member having a portion of the other arm thereof protrudable into the bore for engagement with the said retaining shoulder to prevent axial movement of the pin out of the bore, and having another portion of the said other arm extending from the slot for engagement by an operator for disengagement of the retaining member from the said retaining shoulder.
Claim 3
Dependent Claim
35 words
The invention as claimed in claim 1, wherein the said one arm is frictionally engaged in the slot and is corrugated along its length to increase its frictional engagement with the walls of the slot.
Claim 4
Dependent Claim
62 words
The invention as claimed in claim 1, wherein the said one arm is frictionally engaged in the slot and is corrugated along its length to increase its frictional engagement with the walls of the slot, the portion of the said other arm protruding into the slot being curved to substantially the same radius as the intermediate portion of the pin engaged thereby.
Claim 5
Dependent Claim
82 words
The invention as claimed in claim 1, wherein the said one arm is frictionally engaged in the slot and is corrugated along its length to increase its frictional engagement with the walls of the slot, the portion of the said other arm protruding into the slot being curved to substantially the same radius as the intermediate portion of the pin engaged thereby, and the free end of the said other arm extending from the slot being looped for manipulation by an operator.
Claim 6
Dependent Claim
221 words
A windshield wiper clip assembly for the detachable attachment of a windshield wiper to a wiper arm, the assembly compriSing a clip body, a bore in the body for the reception therein of a wiper arm pin upon which the clip body can pivot about a corresponding axis, the pin having an intermediate portion providing at least one corresponding radially-extending retaining shoulder, a slot in the clip body positioned to register with the said intermediate portion of a pin engaged in the bore, and a U-shaped retaining member mounted in the slot, the retaining member having one arm thereof engaged with at least one slot wall thereof, and having a portion of the other arm thereof protrudable into the bore for engagement with the said retaining shoulder to prevent axial movement of the pin out of the bore, the arms of the retaining member being biased apart by their own resilience and being forced toward each other in the slot against such resilience by insertion of the wiper arm pin into the clip body bore, the resilience maintaining the said engagement of the arm portion with the retaining shoulder, the said other arm of the retaining member having another portion thereof extending from the slot for engagement by an operator for disengagement of the retaining member from the said retaining shoulder.
