Abstract
A wringer mop has a conventional handle with mop fibers extending from a lower point on the handle to a collar that can be lifted to a raised axial position and twisted to wring the mop. The mop also has a pawl on a ring fixed to the handle. When the mop is wrung, the pawl automatically engages a set of raised internal ribs inside the collar to prevent the mop from unwinding. The mop can be returned to normal use by simply pushing the collar down, without the need to fuss with button or levers to disengage the pawl from the ribs.
Claims9
A wringer mop comprising:
- a handle;
- a collar in sliding engagement around the handle;
- mop fibers extending from a lower point on the handle to the collar;
- set of raised ribs on the collar extending parallel to the length of the handle;
- and
- a pawl comprising means for engaging the ribs to limit rotation of the collar to one direction around the handle when the collar is in a raised axial position on the handle, the collar being free to move downwardly as the collar and handle are rotated, and the pawl being disengageable from the ribs by sliding the collar downwardly from the raised axial position.

- a handle;
- a collar in sliding engagement around the handle;
- mop fibers extending from a lower point on the handle to the collar;
- set of raised ribs extending parallel to the length of the handled;
- and
- a pawl with a base that projects axially from a cylindrical section of the mop and a resilient arm that extends from the base at least partially circumferentially around the handle, at a spaced distance from the handle, and terminates in an extending end, the pawl comprising means for engaging the ribs to limit rotation of the collar to one direction around the handle when the collar is in a raised axial position on the handle, the collar being free to move downwardly as the collar and handle are rotated, and the pawl being disengageable from the ribs by sliding the collar downwardly from the raised axial position.
