Height adjustment apparatus for a rotatable component of a vacuum cleaner
First Claim
1. A height adjustment apparatus adapted for a rotatable component of a vacuum cleaner, comprising:
- a rotatable wheel comprising;
a central axis;
a wheel portion substantially centered on the central axis and adapted to be rotated, wherein the wheel portion (102) extends at least partially through a wheel aperture in a vacuum cleaner exterior;
a hub portion substantially centered on the central axis and including an offset axle aperture that is offset from the central axis, with the offset axle aperturebeing adapted to receive at least a portion of the rotatable component;
one or more detent devices formed as part of the hub portion;
a retainer device adapted to be retained in a chassis of the vacuum cleaner, with the retainer device comprising;
a body;
a hub portion aperture formed in the body and of a size to rotatably receive thehub portion of the rotatable wheel;
one or more biasing devices that interact with the one or more detent devices of the hub portion in order to provide a plurality of predetermined detent positions to the height adjustment apparatus, wherein the rotatable component is moved substantially vertically with respect to the central axis when the rotatable wheel is rotated between the plurality of predetermined detent positions; and
wherein a rotatable component height is changed by rotation of the rotatable wheel.

Abstract
A height adjustment apparatus for a rotatable component of a vacuum cleaner is provided. The apparatus includes a rotatable wheel and a retainer device. The rotatable wheel includes a central axis, a wheel portion, a hub portion including an offset axle aperture that receives a rotatable component, and one or more detent devices. The retainer device is retained in a chassis of the vacuum cleaner and includes a body, a hub portion aperture formed in the body and of a size to rotatably receive the hub portion of the rotatable wheel, and one or more biasing devices that interact with the one or more detent devices in order to provide a plurality of predetermined detent positions. The rotatable component is moved substantially vertically with respect to the central axis when the rotatable wheel is rotated between the plurality of predetermined detent positions.

11. A height adjustment system adapted for adjusting a brushroll height of a vacuum cleaner, comprising:
-
a brushroll including a first axle portion extending from a first end of the brushroll and a second axle portion extending from a second end; a first rotatable wheel apparatus extending at least partially through a first wheel aperture in a vacuum cleaner exterior and affixed to a chassis of the vacuum cleaner and including a first offset axle aperture that receives the first axle portion of the brushroll, wherein the first offset axle aperture moves the first axle portion relative to a first rotatable wheel apparatus central axis when the first rotatable wheel apparatus is rotated with respect to the chassis; and a second rotatable wheel apparatus affixed to the chassis and including a second offset axle aperture that receives the second axle portion of the brushroll, wherein the second offset axle aperture moves the second axle portion relative to a second rotatable wheel apparatus central axis when the second rotatable wheel apparatus is rotated with respect to the chassis. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
