    Abstract: An upright vacuum cleaner is provided which includes a sound muffler which, according to one aspect of the invention, may be combined with an accessory selector valve. The vacuum cleaner includes a height adjustment mechanism which eliminates positioning detents along the cam adjustment surface. The vacuum cleaner also includes a vacuum bag mounting arrangement which insures that the bag will not project above a handle parting plane, thus reducing the size of the shipping carton.

  • Patent number: 5414893
    Abstract: The present invention relates to an upright vacuum cleaner having an improved assembly to optimize the assembly and operational characteristics of the vacuum cleaner. The floor engaging unit of the vacuum cleaner has a two-piece body including a base and a hood which are snap-fit together. A motor is rotatably mounted within the body at the end of a handle assembly. The handle assembly, which also functions as a conduit for dirty air to travel to a disposable filter bag, carries an electrical connector which connects the motor to power. The handle further provides a stop which engages a hose hook that slidably fits over the top of the handle, the stop being located such that the hose hook is properly positioned to support a hose during storage thereof. A filter bag, which is mounted to the handle at a location downwardly spaced from the top of the filter bag, is provided with a wire frame to help support the weight of the disposable filter bag.
