Abstract
Self-wringing mop includes a compressible head of sponge rubber or the like and a wringing mechanism which comprises a presser plate pivotable into compressive engagement with the mop head, an operating lever pivotally mounted on the mop handle, a cam lever pivotally connected to the operating lever and a cam disposed on the end of the cam lever such that actuation of the operating handle causes the cam to reciprocate over the surface of the presser plate while pivotally urging the presser plate into compressive engagement with the mop head.
Claims12
Self-wringing mop comprising a compressible mop head fixed on the end of an elongated handle, a pressure plate pivotable into compressive engagement with said mop head, an operating lever pivotally mounted on said handle, a cam arm pivotally attached at an end thereof to said operating lever such that pivoting of said operating lever drives said cam arm toward said mop head, and a roller cam carried by said cam arm and movable reciprocably over a raised follower on the outer surface of said presser plate while pivotally urging said presser plate into compressive engagement with said mop head.
Self-wringing mop comprising a compressible mop head disposed on the end of an elongated handle, a wringing mechanism supported by said handle said wringing mechanism including a wringer plate pivotally mounted adjacent said head and a manually actuable cam engageable with said wringer plate wherein said cam is movable along an arcuate path reciprocally over a raised cam follower on the outer surface of said wringer plate to thereby cause said wringer plate to pivot into compressible engagement with said head.
Self-wringing mop comprising a compressible mop head fixed on the end of an elongated handle, a presser plate pivotable into compressive engagement with said mop head, an operating lever pivotally mounted on said handle, a cam arm pivotally attached at an end thereof to said operating lever, a link pivotally attached at its ends to said elongated mop handle and a median portion of said cam arm, said link being disposed generally parallel to said operating lever whereby said elongated handle, operating handle link and cam arm comprise a parallelogrammatic linkage and pivoting of said operating lever drives said cam arm toward said mop head, and a cam, carried by said cam arm, and movable reciprocably over the outer surface of said presser plate while pivotally urging said presser plate into compressive engagement with said mop head.
