Removable rotatable driven agitator for surface cleaning head
First Claim
1. A removable rotatable agitator assembly for use in a surface cleaning head of a vacuum, the removable rotatable agitator assembly comprising:
- an agitator body having a driven end and a non-driven end;
at least one agitating element located on at least a portion of the agitator body between the driven end and the non-driven end;
a driven member located at the driven end of the agitator body, the driven member being configured to mate axially and engage with a drive member on a drive mechanism in the surface cleaning head;
an axle extending from the non-driven end of the agitator body and fixed within the agitator body such that the axle rotates with the agitator body;
a bushing rotatably mounted on the axle; and
an end cap mounted on the bushing and configured to be mounted without rotation in an agitator chamber of the surface cleaning head, wherein the end cap secures the bushing such that the axle rotates within the bushing and the agitator body spins about an axis of rotation, wherein the end cap includes a tab extending radially outward relative to the end cap and the agitator body and toward an opening of the agitator chamber to allow the tab to be gripped by a user when the agitator assembly is within the agitator chamber of the surface cleaning head, wherein the tab is positioned such that a radially outward force applied to the tab in a substantially radial direction relative to an axis of rotation of the agitator body causes the non-driven end to be removed from the agitator chamber, wherein the tab extends along only a portion of a circumference of the end cap such that a width of the tab is less than a diameter of the end cap and wherein the tab is spaced axially in from an end of the end cap, and wherein the end cap includes a radially outward facing portion extending along a portion of the circumference of the end cap adjacent the tab and configured to be engaged by an engaging structure on an external cover in a closed position on the surface cleaning head such that the engaging structure on the cover engages the radially outward facing portion in a radial direction to hold and secure the agitator assembly in the agitator chamber of the surface cleaning head.

Abstract
A removable rotatable driven agitator is used in a surface cleaning head and is driven by a drive mechanism that axially engages a driven end of the agitator. The removable rotatable driven agitator may be located in an openable agitator chamber for purposes of removing debris and/or removing the agitator. The openable agitator chamber may be covered by an external cover that is movable between an open position and a closed position. The removable agitator may be secured in the agitator chamber by the external cover. The removable rotatable agitator may have an end cap mounted on a rotatable bushing at a non-driven end and may have a splined driven member at the driven end to engage a splined drive member on the drive mechanism.
