Concave/Swivel Vacuum Cleaner Attachment For Improved Reach

[Category : - Cleaning devices]
[Viewed 434 times]

A vacuum cleaner attachment is disclosed having a concave vacuum head with a swivel joint that permits swiveling of the vacuum head only within the plane of the vacuum head. The concave vacuum head can have a curvature that is similar to the curvature of a cylindrical surface to be vacuumed. Thus, while a user manipulates the conduit providing the air suction to the vacuum head, the concave surface can be supported and swiveled around the circumference of the cylindrical surface to be vacuumed, while the vacuum head is also moved along the length of the cylindrical surface. Throughout this movement of the concave vacuum head, the concave opening of the concave vacuum head can stay in closer proximity and conformity to the cylindrical surface than is possible using a fixed vacuum head with a flat opening, thereby making cleaning of the cylindrical surface more effective and efficient.

It is a significant enhancement that enables a vacuum cleaner to clean curved surfaces with comparable efficiency to how a standard vacuum cleaner attachment cleans straight surfaces: “In such cases,” Ms. O’Neill’s patent observes, “the flat opening fails to get sufficient simultaneous proximity and conformity to the curved surface of the cylinder (e.g., a log, a pipe, a round post), substantially reducing the ability of the attachment to use suction to clean the surface.”

As well, thanks to the synergistic combination of the additional reach enabled by the swivel joint mechanism and the concave shape of the attachment, Ms. O’Neill’s invention allows its users to clean corners and edges/crevices of curved surfaces almost effortlessly. While the concave attachment is very important, the cleaning of curved surfaces won’t work properly without the swivel motion. Logs have crevices where the joints meet as do overhead pipes. “One”, as the inventor has stated, “isn’t any good without the other.”
