Abstract
A gear-driven cleaning device having two gear components attached to the elongate handle. The first gear component providing torque for driving the second gear component which drives a wringing component. The cleaning device also having a pawl and ratchet arrangement for preventing the handle from rotating in a predetermined direction during the wringing process.
Claims17
A wringing device for squeezing absorbed liquid from an attached cleaning attachment, comprising:
- a handle grip;
- a gear component operationally connected to said handle grip so that rotation of said handle grip drives said gear component;
- an elongate member operationally connected to said gear component, wherein said gear component drives said elongate member in a predetermined rotational direction;
- a moveable component operationally connected to said gear component, wherein said gear component drives said moveable component in a rotational direction opposite to said elongate member;
- wherein rotation of said handle grip drives said gear component which drives rotation of said elongate member and moveable component in opposite directions to wring the attached cleaning attachment;
- and
- wherein said moveable component moves along a length of said elongate member as the attached cleaning attachment is wrung.

A wringing device for squeezing absorbed liquid from an attached cleaning attachment, comprising:
- a gear component;
- an elongate member operationally connected to said gear component, wherein said gear component drives said elongate member in a predetermined rotational direction;
- a moveable component operationally connected to said gear component, wherein said gear component drives said moveable component in a rotational direction opposite to said elongate member;
- wherein said actuation of said gear component drives the rotation of said elongate member and moveable component in opposite directions to wring the attached cleaning attachment;
- wherein said gear component is further comprised of a first gear component which drives said elongate member in a predetermined direction while driving a second gear component which drives said moveable component in a rotational direction opposite to said elongate member and where in the interaction of the first and second gear components provide enhanced torque in wringing the attached cleaning attachments;
- a retaining device attached to a distal end of said elongate member, wherein a distal end of the cleaning attachment is attached to said retaining device, and wherein a proximal end of the cleaning attachment is attached to said moveable component, and wherein wringing of the cleaning attachment by rotation of said elongate member in one direction and the moveable component in the other direction causes the compression of the cleaning attachment and movement of said moveable component toward said distal end of said elongate member during the wringing process;
- and
- a spring operationally connected to said wringing device to provide a spring bias against said moveable component as said moveable component moves down the length of said elongate member.

A wringing device for squeezing absorbed liquid from an attached cleaning attachment, comprising:
- handle grip;
- a gear component operationally connected to said handle grip so that rotation of said handle grip drives said gear component;
- an elongate member operationally connected to said gear component, wherein said gear component drives said elongate member in a predetermined rotational direction;
- a moveable component operationally connected to said gear component, wherein said gear component drives said moveable component in a rotational direction opposite to said elongate member;
- wherein rotation of said handle grip drives said gear component which drives rotation of said elongate member and moveable component in opposite directions to wring the attached cleaning attachment;
- and
- wherein said moveable component moves along a length of said elongate member and wherein a portion of the cleaning attachment is attached to an end of said elongate member.
