Abstract: A pivot connection for connecting the wand of a vacuum cleaner hose to a vacuum cleaner nozzle of the type having an exhaust aperture through which air is drawn into a vacuum hose. A three-sided curved duct extends upwardly from a top surface of the nozzle, the duct having a transverse generally rectangular cross section with a curved front wall and contiguous laterally opposed side walls. The front wall and side walls have lower portions surrounding the exhaust aperture on three sides, upper ends defining a generally rectangular open end disposed in an angular plane with respect to a vertical axis, and interior surfaces forming an arcuate extension of the exhaust aperture.

Abstract: A vacuum nozzle adapted for use on a working surface has a generally rectangular main body portion with a top surface, a bottom surface, an outer periphery, and a central aperture through the main body portion for connection to a vacuum hose connected to a vacuum source. The main body portion may be slightly concave or flat. Spacers on the bottom surface support the main body portion above a surface to be cleaned at a predetermined height. The size and shape of the bottom surface, and its height above the surface to be cleaned are designed to draw air between the surface to be cleaned and the bottom surface of the nozzle at a substantially uniform velocity which is proportional to the inflow velocity of the vacuum hose connected with the nozzle, and to maintain little or no difference in static pressure between the air under the nozzle and the static pressure of the air above the nozzle.
