Claims59
An upright vacuum cleaner comprising:
- a main body comprising—
- a motor configured to drive a fan to induce airflow through the vacuum cleaner and lift debris entrained in the airflow;
- a floor engaging power head rotatably secured to the main body, the power head comprising—
- an opening through which the airflow enters the power head and ingests debris entrained in the airflow into the vacuum, and
- a brush configured to agitate the debris and thereby assist in lifting and entraining the debris in the airflow;
- a main support secured to the main body and thereby rotatably secured to the power head at a first end and including—
- a handle at an opposing second end, and
- a control switch configured to selectively apply power to the motor;
- and
- a container assembly configured to filter the airflow and thereby collect the debris entrained in the airflow, the container assembly including—
- a container secured to the main support,
- a door rotatably secured to the container, and
- a latch assembly including a cam lock rotatably secured to the door and configured to selectively engage the main support and thereby hold the door closed, such that the door is in sealing engagement with the container,
- wherein the latch assembly further includes at least one stop positioned to limit rotation of the cam lock and at least one spring configured to bias the cam lock in a select position, and
- wherein the cam lock includes a substantially cylindrical portion about which the cam lock rotates, the cylindrical portion having an curved outer surface and at least one flat surface formed in the curved outer surface positioned to engage the spring and thereby bias the cam lock in the select position.

- a container secured to the main support,
- a door rotatably secured to the container, and
- a latch assembly including a cam lock rotatably secured to the door and configured to selectively engage the main support and thereby hold the door closed, such that the door is in sealing engagement with the container,
- wherein the door is colored a first color and the cam lock is colored a second color, the second color contrasting with the first color, thereby making the cam lock distinguishable from the door and operation of the latch assembly recognizable.
