Abstract

A dust shroud for an angle grinder includes an access hatch which slides along the shroud body to selectively expose an edge of a grinding disc to allow grinding into a corner. The hatch remains attached to the shroud body in both the open and closed position, making the hatch easier to use and less likely to become lost, resulting in increased worker compliance in properly using the hatch.

Claims

1. A dust shroud for an angle grinder comprising:

a shroud body configured to enclose a grinding disc;

a vacuum port attached to the shroud body to draw air from inside of the shroud body;

a mounting mechanism for attaching the shroud body to an angle grinder;

an access hatch on the shroud body, the access hatch being slideably attached to the shroud body so as to allow the hatch to slide from a closed position to an open position while remaining attached to the shroud body, the close position causing the shroud to enclose a grinding disc, the open position exposing a side of the grinding disc.

2. The dust shroud of claim 1, wherein the shroud body comprises a generally flat upper surface and a skirt extending downwardly therefrom.

3. The dust shroud of claim 1, wherein the shroud body is circular in shape, and wherein the access hatch slides along the circumference of the shroud body.

4. The dust shroud of claim 3, further comprising an upper guide disposed on the top of the shroud body and a lower guide disposed along a skirt extending downwardly from the top of the shroud body, and wherein the hatch slides along the upper guide and the lower guide to move in a circular direction around the shroud body.

5. The dust shroud of claim 1, wherein the shroud body is circular in shape, and wherein the access hatch slides in a circular direction about the axis of the grinder output shaft.

6. The dust shroud of claim 1, wherein the shroud body has a curved upper guide, the upper guide defining a guide channel and wherein the access hatch has a portion extending into the guide channel and being captively held therein such that the access hatch can slide around the shroud body.

7. The dust shroud of claim 6, wherein the shroud body has stops formed thereon for selectively holding the access hatch in an open position or a closed position.

8. The dust shroud of claim 1, wherein the shroud body has bristles extending downwardly from an outer edge thereof and wherein the access hatch has bristles extending downwardly from an outer edge thereof, and wherein the access hatch is selectively closeable such that the bristles form a circle and wherein the access hatch is selectively openable such that the bristles form a portion of a circle having an opening therein.

9. A dust shroud for an angle grinder comprising:

a shroud body having an upper surface and a skirt extending downwardly therefrom so as to generally enclose a grinding disc, the shroud body having a side opening on a side thereof, the side opening allowing a portion of the grinding disc to extend through the side opening such that said portion of the grinding disc is not covered by the shroud body;

a center opening in the center of the shroud body for receiving the output shaft of an angle grinder;

a mount adjacent the opening for attachment to the angle grinder;

an access hatch slidably attached to the shroud body, the access hatch being slidable between an open position wherein the access hatch does not substantially cover the side opening and a closed position wherein the access hatch covers the side opening.

10. The dust shroud of claim 9, further comprising a vacuum port connected to the shroud body to draw air from around the grinding disc.

11. The dust shroud of claim 9, wherein the shroud body is generally circular, and wherein the access hatch slides circumferentially around the outside of the shroud body.

12. The dust shroud of claim 11, wherein the shroud body has bristles extending downwardly from the perimeter thereof.

13. The dust shroud of claim 9, wherein the shroud body has an upper guide channel formed thereon, and wherein the access hatch is slidably received in the upper guide channel to control the movement thereof.

14. The dust shroud of claim 13, wherein the access hatch engages the lower perimeter of the shroud body.

15. The dust shroud of claim 9, wherein the shroud body has stops to limit the motion of the access hatch.
