Abstract

Claims (27)

1 . A vacuum tool for removably coupling to a hose or wand of a vacuum, the vacuum tool comprising:

a distal end having an inlet;

a proximal end opposite the distal end; and

a connection portion disposed adjacent the proximal end, the connection portion including

an inner wall forming a conduit in fluid communication with the inlet, the conduit defining a central axis extending therethrough, the conduit including an outlet at the proximal end, the outlet configured to be placed in fluid communication with the hose or wand of the vacuum, the inner wall having an outermost surface forming a width of the conduit that remains constant or decreases along an entire length of the inner wall toward the proximal end,

an annular end wall coupled to the inner wall and extending radially outwardly from the inner wall relative the central axis and in in a direction that is generally perpendicular relative the central axis,

a flare wall extending radially outwardly relative the central axis and from the annular end wall at an oblique angle, the flare wall including a radially outer surface and a radially inner surface, the radially outer surface forming an outermost surface of the connection portion and the vacuum tool,

an outer wall extending from the flare wall, the 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.

2 . The vacuum tool of claim 1 , wherein the annular channel narrows in a direction away from the proximal end.

3 . The vacuum tool of claim 2 , wherein the inner wall includes a shoulder formed on the outermost surface of the inner wall.

4 . The vacuum tool of claim 3 , wherein the shoulder is a first shoulder, and the inner wall further includes a second shoulder formed on the outermost surface of the inner wall, the first shoulder protruding radially outwardly a greater distance than the second shoulder.

5 . The vacuum tool of claim 4 , wherein the second shoulder is nearer to the proximal end than the first shoulder is to the proximal end.

6 . The vacuum tool of claim 4 , wherein the inner wall further includes a third shoulder protruding radially inwardly from an inner surface of the inner wall.

7 . The vacuum tool of claim 6 , wherein the inner wall further includes a fourth shoulder protruding radially inwardly from the inner surface of the inner wall, the third shoulder protruding radially inwardly a greater distance than the fourth shoulder.

8 . The vacuum tool of claim 7 , wherein the fourth shoulder is nearer to the proximal end than the third shoulder is to the proximal end.

9 . The vacuum tool of claim 1 , wherein the connection portion is formed as a unitary piece.

10 . The vacuum tool of claim 1 , wherein the outlet is circular.

11 . The vacuum tool of claim 1 , wherein the inner wall and the outer wall are generally cylindrical.

12 . The vacuum tool of claim 1 , wherein the outer wall includes a rounded end.

13 . The vacuum tool of claim 12 , wherein the inner wall includes a rounded end.

14 . The vacuum tool of claim 1 , wherein

each of the radially outer surface and the radially inner surface extends radially outwardly relative the central axis and from the annular end wall at the oblique angle.

15 . The vacuum tool of claim 1 , wherein the outer wall and the flare wall meet at an outermost edge of the connection portion.

16 . The vacuum tool of claim 15 , wherein the outer wall is coupled only to the flare wall and extends from the flare wall along the central axis in a direction away from the distal end.

17 . The vacuum tool of claim 16 , wherein the outer wall is coupled at one end to the flare wall and has an opposite free end.

18 . The vacuum tool of claim 17 , wherein the outer wall has a linear radially inner surface along an entire length of the outer wall.
