Abstract
A self-wringing ratchet mop including an elongated handle, a mop head having mop strands supported on the handle, and a wringing mechanism for wringing the mop strands. The wringing mechanism includes a sleeve attached to the mop strands and supported for longitudinal and rotational movement relative to the handle. The handle includes a first ratchet portion formed by teeth and the sleeve includes a second ratchet portion formed by pawl members for engaging the first ratchet portion to permit the sleeve to rotate in a first direction and prevent rotation in a second, opposite direction. The pawl members are supported on a deformable resilient ring wherein deformation of the ring causes the pawl members to disengage from the first ratchet portion and permit rotation of the sleeve in the second direction.
