Upright vacuum cleaner
First Claim
1. An upright vacuum cleaner comprising:
- an upper section including a handle;
a lower cleaning nozzle section connected to the upper section and including an underside with a main suction opening formed therein;
a suction source;
an edge cleaning tool including a suction bore formed therethrough;
a fastener provided as a part of at least one of said cleaning nozzle section and said edge cleaning tool for selectively connecting said edge cleaning tool to the lower cleaning nozzle section; and
,conduit means for selectively connecting said suction source in fluid communication with one of said main suction opening of said nozzle and said suction bore of said edge cleaning tool, to thus establish a suction force at said one of said main suction opening of said nozzle and said suction bore of said edge cleaning tool, respectively.

Abstract
An upright vacuum cleaner is provided and includes an upper section with a handle (15) and a lower cleaning nozzle section (14, 14'"'"') having a main suction opening (18) formed in the underside (16) thereof. A suction source (M) is provided and an edge cleaning tool (60) having a suction bore (64) formed therethrough is releasably connected to the cleaning nozzle section (14'"'"'). A suction hose (20) selectively connects one of the main suction opening (18) of the nozzle (14'"'"') and the suction bore (64) of the edge cleaning tool (60) with the suction source (M). First and second laterally spaced casters (30a, 30b) extend from the underside (16) of the nozzle (14, 14'"'"') and each caster (30a, 30b) is pivotable respectively about a vertical axis (D,E). First and second laterally spaced fixed wheels (32a, 32b), each rotatable about a single rolling axis (C), are also provided and positioned forward of the first and second casters (30a, 30b). Each fixed wheel (32a, 32b) includes a rolling surface (40a, 40b) and curved inner and outer transition surfaces (42a, 42b), (44a, 44b) connecting its rolling surface (40a, 40b) to the inner and outer sides (42a, 42b), (44a, 44b) of the wheel (32a, 32b).
