Abstract
A vacuum cleaner suction nozzle having a rotating agitator is provided with at least a rearward suction duct extending transversely along the nozzle and having a bottom side serving as the rear lip of the nozzle. A forward suction duct may also be included in a similar configuration and have a bottom side formed by a front lip of the nozzle. The rear and/or forward suction ducts may also include a constant velocity attribute by increasing in size from their entrant ends to their discharge ends.
Claims23
A suction nozzle having a rear discharge duct including:
- a) a nozzle body;
- b) a sidewardly extending duct communicating with said rear discharge duct;
- c) said sidewardly extending duct being disposed to extend transversely along said nozzle body;
- d) said sidewardly extending duct including a bottom wall;
- e) said bottom wall forming a nozzle supporting lip;
- f) said sidewardly extending duct also including a pair of vertically extending walls;
- g) one of said vertically extending walls being spaced from said supporting lip to provide an open slot for air and dirt impingement on said nozzle supporting lip and transport along said sidewardly extending duct;
- and
- h) said sidewardly extending duct providing a constant air flow velocity characteristic by expanding in cross-section area along said nozzle body toward said rear discharge duct.
A suction nozzle having a rear discharge duct including:
- a) a nozzle body;
- b) a sidewardly extending duct communicating with said rear discharge duct;
- c) said sidewardly extending duct being disposed to extend transversely along said nozzle body;
- d) said sidewardly extending duct including a pair of vertically extending walls;
- e) an agitator disposed in said nozzle body;
- and
- f) said duct having a bottom wall forming a substantially continuously flat, horizontally extending bottom support lip for said suction nozzle.
The suction nozzle having a rear discharge duct as set out in claim 12 wherein:
- a) said sidewardly extending duct provides a constant air velocity characteristic by expanding in cross-sectional area along said nozzle body towards said rear discharge duct.

- d) said sidewardly extending duct including a pair of vertically extending walls;
- e) an agitator disposed in said nozzle body;
- and
- f) said sidewardly extending duct being disposed along the front side of said nozzle body.
A suction nozzle having a rear discharge duct including:
- a) a nozzle body;
- b) a sidewardly extending duct communicating with said rear discharge duct;
- c) said sidewardly extending duct being disposed to extend transversely along said nozzle body;
- d) said sidewardly extending duct including a pair of vertically extending walls;
- e) an agitator disposed in said nozzle body;
- and
- f) said sidewardly extending duct being paired to provide a duct along both the front and rear sides of said nozzle body.
A suction nozzle having a rear discharge duct including:
- a) a nozzle body;
- b) a pair of sidewardly extending ducts communicating with said rear discharge duct;
- c) said sidewardly extending ducts being disposed to extend transversely along said nozzle body;
- and
- d) said sidewardly extending ducts being disposed on the front and rear sides of said nozzle body.
