Publication number: 20120023701Abstract: A latch mechanism for a dirt cup of a vacuum cleaner. The latch mechanism can include a first sloped portion provided on a mounting structure for receiving a dirt cup and a filter housing in supporting relationship to the vacuum cleaner and a second sloped portion on the filter housing corresponding to the first sloped portion. Movement of the filter housing in a first direction relative to the mounting structure as the first and second sloped portions bear against each other results in the movement of the filter housing, and thus the dirt cup, in a second direction transverse to the first direction relative to the mounting structure.Type: ApplicationFiled: July 26, 2011Publication date: February 2, 2012Inventors: Kenneth M. Lenkiewicz, Bruce Xue
