Vacuum conduit attachment tool for connection to different sized vacuum conduits
First Claim
1. A vacuum cleaning system comprising:
- a suction unit;
a vacuum conduit connected to the suction unit; and
an attachment tool connected to an end of the vacuum conduit, the attachment tool including;
a hollow body extending from a first end to a second end and defining a flow path, the first end defining an inlet for receiving debris therethrough; and
a conduit connector disposed at the second end of the body, the conduit connector including an outer collar defining a first inner engagement surface, and an inner collar concentric with the outer collar and defining a second inner engagement surface, each of the outer collar and the inner collar terminating at a respective free end, wherein the free end of the inner collar is axially offset from the free end of the outer collar towards the first end of the hollow body;
wherein the attachment tool is configured as one of a crevice tool, a dusting brush, a car nozzle, a floor brush, a floor tool, a utility nozzle, and a triangular dusting brush, and is connected to the vacuum conduit along one of the first inner engagement surface and the second inner engagement surface, and wherein the attachment tool is selectively attachable to vacuum conduits of different diameters along the first and second inner engagement surfaces.

Abstract
An attachment tool for a vacuum cleaning system includes a hollow body that extends from a first end to a second end and defines a flow path, and a conduit connector disposed at the second end of the body. The first end of the hollow body defines an inlet for receiving debris therethrough. The conduit connector includes an outer collar that defines a first inner engagement surface for connection to an outer diameter of a first vacuum conduit, and an inner collar that is concentric with the outer collar and defines a second inner engagement surface for connection to an outer diameter of a second vacuum conduit smaller than the outer diameter of the first vacuum conduit. The inner collar is axially offset from the outer collar towards the first end of the body.

20. A method of assembling a vacuum cleaning system, the method comprising:
-
providing a suction unit, a vacuum conduit, and an attachment tool configured as one of a crevice tool, a dusting brush, a car nozzle, a floor brush, a floor tool, a utility nozzle, and a triangular dusting brush, the attachment tool including a hollow body extending from a first end to a second end and defining a flow path, and a conduit connector disposed at the second end of the body, the conduit connector including an outer collar defining a first inner engagement surface, and an inner collar concentric with the outer collar and defining a second inner engagement surface, each of the outer collar and the inner collar terminating at a respective free end, the free end of the inner collar axially offset from the free end of the outer collar towards the first end; connecting a first end of the vacuum conduit to the suction unit; determining a diameter of a second end of the vacuum conduit; selecting, based on the diameter of the second end of the vacuum conduit, one of the engagement surfaces of the attachment tool for connection to the vacuum conduit; and connecting the vacuum conduit to the selected engagement surface.
