Abstract

Claims (44)

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,

a ledge coupled to a sidewall of the at least four sidewalls, the ledge extending along and protruding outward from the sidewall, the ledge including a surface extending in a direction transverse to the sidewall,

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 the ledge and disposed on the surface of the ledge, the surface of the ledge being disposed nearer to an inlet end of the sidewall in a direction parallel to the sidewall than at least a portion of the magnet is to the inlet end of the sidewall in the direction parallel to the sidewall, the portion of the magnet being disposed nearer to the outlet of the connection portion in the direction parallel to the sidewall than the surface of the ledge is to the outlet of the connection portion in the direction parallel to the sidewall.

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 sidewall is a farthest extending sidewall, of the at least four sidewalls, 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 sidewall 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,

a ledge coupled to a wall of the plurality of walls, the ledge extending along and protruding outward from the wall, the ledge having a first surface and an opposite second surface, the first surface being nearer to the inlet than the second surface is to the inlet, each of the first surface and the second surface extends in a direction transverse to the wall,

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 the ledge, at least a portion of the magnet disposed adjacent the second surface of the ledge, such that the second surface is disposed between the portion of the magnet and the first surface on an imaginary line that intersects the first surface, the second surface, and the portion of the magnet.

15 . The vacuum tool of claim 14 , wherein the magnet spans a majority of the wall 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 wall 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.
