Abstract

A vacuum tool configured to be removably coupled to hose or wand of a vacuum includes a body including a first end, a second end, and a first longitudinal axis extending between the first end and the second end. The vacuum tool also includes a head coupled to the first end of the body, a connection portion coupled to the second end of the body and configured to couple the body to a hose or wand of a vacuum cleaner, and a brush coupled to the head. The brush includes an elongate support defining a second axis perpendicular to the longitudinal axis of the body and configured to couple the brush to the head, and a plurality of bristles positioned on the elongate support.

First claim

What is claimed is:

1 . A vacuum tool for removably coupling to a hose or wand of a vacuum, the vacuum tool comprising:
a body including
a frustopyramidal base portion having at least four sidewalls forming an inlet and a cavity therebetween, the cavity in fluid communication with the inlet and tapering in a direction away from the inlet,
an intermediate portion extending from the base portion, the intermediate portion being narrower than the base portion and having a conduit defined therein, the conduit in fluid communication with the cavity of the base portion, and
a connection portion extending from the intermediate portion, the connection portion having
an inner wall,
a conduit formed by the inner wall, the conduit of the connection portion in fluid communication with the conduit of the intermediate portion, the conduit of the connection portion including an outlet configured to be placed in fluid communication with the hose or wand of the vacuum,
an outer wall surrounding a majority of the inner wall, and
an annular channel formed between the inner wall and the outer wall, the annular channel configured to receive an end of the hose or wand of the vacuum; and

a magnet coupled to one of the at least four sidewalls of the base portion adjacent the inlet.

2 . The vacuum tool of claim 1 , wherein
the inlet lies along an inlet plane, the outlet lies along an outlet plane, and the inlet plane and the outlet plane form an oblique angle therebetween.

3 . The vacuum tool of claim 2 , wherein
the at least four sidewalls of the base portion include a sidewall extending farthest from the outlet, and the magnet is coupled to the sidewall extending farthest from the outlet.

4 . The vacuum tool of claim 3 , wherein the magnet spans across a majority of a length of the inlet.

5 . The vacuum tool of claim 4 , wherein the magnet spans across an entirety of a side of the inlet, the side of the inlet formed by the sidewall extending farthest from the outlet.

6 . The vacuum tool of claim 1 , wherein the outer wall of the connection portion is wider than the intermediate portion where the intermediate portion meets the connection portion.

7 . The vacuum tool of claim 1 , wherein the base portion has at least eight sidewalls including the at least four sidewalls.

8 . The vacuum tool of claim 7 , wherein the inlet is rectangular with chamfered corners.

9 . The vacuum tool of claim 8 , wherein the outlet is circular.

10 . The vacuum tool of claim 1 , wherein the one of the at least four sidewalls is disposed between the magnet and the cavity of the base portion.

11 . The vacuum tool of claim 1 , wherein the conduit of the intermediate portion is narrower than the cavity of the base portion.

12 . The vacuum tool of claim 1 , wherein the body is formed as a single unitary part.

13 . The vacuum tool of claim 1 , wherein the inner wall is an inner cylindrical wall and the outer wall is an outer cylindrical wall.

14 . A vacuum tool for removably coupling to a hose or wand of a vacuum, the vacuum tool comprising:
a body including
a base portion having a plurality of walls forming an inlet, the plurality of walls angled toward one another such that the base portion tapers along a direction away from the inlet,
an intermediate portion coupled to the base portion, the intermediate portion being narrower than the base portion, and
a connection portion coupled to the intermediate portion, the connection portion having
an annular end wall surrounding the intermediate portion where the connection portion couples to the intermediate portion,
a flare wall extending radially outwardly relative the annular end wall at an oblique angle,
an outer wall extending from the flare wall,
an inner wall disposed radially inwardly from the outer wall, the inner wall forming an outlet, the outlet in fluid communication with the inlet and configured to be placed in fluid communication with the hose or wand of the vacuum, and
an annular channel formed between the outer wall and the inner wall, the annular channel configured to receive an end of the hose or wand of the vacuum; and

a magnet coupled to one of the plurality of walls of the base portion.

15 . The vacuum tool of claim 14 , wherein the magnet spans a majority of the one of the plurality of walls in a direction parallel to a plane in which the inlet lies.

16 . The vacuum tool of claim 14 , wherein each of the inner wall and the outer wall is generally cylindrical.

17 . The vacuum tool of claim 16 , wherein each of the inner wall and the outer wall extends generally parallel to a direction that is perpendicular to the annular end wall of the connection portion.

18 . The vacuum tool of claim 14 , wherein the magnet is disposed on a side of the one of the plurality of walls that is opposite the inlet.

19 . The vacuum tool of claim 14 , wherein the inlet is rectangular with chamfered corners.

20 . A method of operating a vacuum tool, the method comprising:
inserting an end of a hose or wand of a vacuum into an annular channel formed between an outer wall and an inner wall of a connection portion of the vacuum tool; activating the vacuum, thereby creating suction through an inlet of the vacuum tool; moving the inlet of the vacuum tool over a work surface; picking up a ferromagnetic material from the work surface with a magnet coupled to a leading edge of the vacuum tool adjacent the inlet of the vacuum tool; and picking up a non-ferromagnetic material from the work surface with the suction through the inlet of the vacuum tool.
