대표청구항 ▼

1. A vacuum shroud for an angle grinder comprising: a body having an upper surface and a skirt attached thereto and extending downwardly from the upper surface so as to define an interior space so as to generally enclose a grinding disk of an angle grinder in said interior space;a hole formed in the center of the upper surface and a grinder mount located around the hole and extending upwardly from the upper surface for securing the shroud to an angle grinder;a vacuum port attached to the body and disposed in fluid communication with the interior space of the body;a removable hatch forming part of the skirt, the hatch being configured such that an edge of a grinding disk is exposed when the hatch is removed from the body, the hatch being removable from the body by sliding the hatch downwardly relative to the body; anda first mount disposed on the skirt and configured to receive the hatch in a closed position wherein the hatch covers said edge of the grinding disk; anda second mount disposed on the shroud and configured to receive the hatch in a storage position wherein the hatch does not cover said edge of the grinding disk. 2. The shroud of claim 1, wherein the grinder mount comprises a collar extending upwardly from the upper side of the body, the collar being configured for attachment to the body of an angle grinder. 3. The shroud of claim 2, wherein the collar has vertical slots formed therethrough. 4. The shroud of claim 1, wherein the body includes holes formed in the top thereof to allow some air flow through the top of the shroud. 5. The shroud of claim 1, wherein removal of the hatch exposes about five percent of the diameter of a grinding disk. 6. The shroud of claim 1, wherein the first mount holds the hatch in a position where the hatch forms a continuous part of the skirt. 7. The shroud of claim 1, wherein the hatch comprises tabs extending from the ends thereof and wherein the first mount comprises recesses formed in the bottom of the skirt to receive the tabs. 8. The shroud of claim 1, wherein the second mount is disposed on the upper surface of the body. 9. A dust shroud for an angle grinder comprising: a generally circular body, the body having a generally flat upper surface and a skirt extending downwardly therefrom so as to form an interior cavity for generally enclosing the top and sides of a grinding disk;a grinder mount for securing the shroud to an angle grinder so as to place the grinding disk within said interior cavity;a vacuum port attached to the body and attachable to a vacuum hose, the vacuum port being disposed in fluid communication with the interior cavity such that a vacuum attached thereto draws air from around the grinding disk;a selectively removable hatch formed on a side of the body such that removal of the hatch allows a grinding disk to protrude from an opening in the body, the hatch being removable from the body by sliding the hatch downwardly relative to the body;a first mount formed at said opening and configured to selectively receive the hatch therein, the first mount being formed so as to position the hatch over said opening and enclose the grinding disk; anda second mount formed on the shroud and configured to selectively receive the hatch therein in a storage position such that the hatch does not cover said opening and such that a grinding disk protrudes from said opening. 10. The shroud of claim 9, wherein said second mount is disposed on the upper surface of the body. 11. The shroud of claim 9, wherein the hatch forms a continuous portion of the body when disposed in the first mount. 12. The shroud of claim 9, wherein the hatch has tabs extending therefrom, wherein the first mount has corresponding recesses formed in the bottom of the skirt to receive said tabs to thereby secure the hatch in the first mount, and wherein the second mount has corresponding recesses formed therein to receive said tabs to thereby secure the hatch in the second mount. 13. A method of using an angle grinder vacuum shroud comprising: selecting an angle grinder having a vacuum shroud disposed thereon, the vacuum shroud having a shroud body with an upper surface and a skirt extending downwardly from the upper surface and away from the grinder and comprising a hatch on a side thereof, the hatch being selectively removable so as to selectively cover or expose an opening in the side of the shroud;removing the hatch from the side of the shroud by sliding the hatch downwardly relative to the shroud body and away from the grinder in order to expose a side of a grinding disk such that the grinding disk protrudes from said opening so as to facilitate grinding with the grinding disk; andplacing the hatch in a mount disposed on the top of the shroud so as to secure the hatch to the shroud while grinding. 14. The method of claim 13, wherein the method further comprises removing the hatch from the mount after grinding and securing the hatch to the side of the shroud so as to cover the side of the grinding disk. 15. The method of claim 13, wherein removing the hatch from the side of the shroud exposes about five percent of the grinding disk.
