Abstract
A universal dust shroud includes a unitary mounting bracket on top of the shroud body. The bracket includes a plurality of collar sections attached to the body via a ‘Z’ shaped joint which allows the collar sections to move radially inwardly and outwardly relative to each other to accommodate different angle grinders. The bracket may include slots formed at the base of the bracket. The slots allow air to flow in through the slots, out past the grinding disk, and to the vacuum port. As such, the slots can aid in cooling the grinder output and bearings, and helps keep dust and debris away from the bearings in order to extend the life of the grinder.
Claims19
A dust shroud for use with an angle grinder comprising:
- a shroud body having a an upper surface and a skirt extending downwardly therefrom so as to generally enclose a grinding disk in the interior thereof, the upper surface having an opening formed in the center thereof for allowing the shaft of an angle grinder to pass therethrough, the shroud extending horizontally from a central axis;
- a vacuum port attached to the shroud body, the vacuum port being in fluid communication with the interior of the shroud body;
- an attachment collar extending upwardly from the shroud body and around said opening in said center of the shroud body, the collar having a plurality of generally vertical slots therethrough such that the collar comprises a plurality of separated generally vertical sections;
- and
- a plurality of joints between the base of the collar and the top of the shroud body, each joint corresponding to one of the vertical sections of the collar, each joint comprising a Z shaped section so as to allow the vertical sections of the collar to move radially inwardly and outwardly to vary the size of the collar.
A dust shroud for use with an angle grinder comprising:
- a shroud body having an upper surface and a skirt extending downwardly from the upper surface;
- a vacuum port having a first end connected to the shroud body and having a second end configured for connection to a vacuum hose to thereby draw air from the shroud body, through the vacuum port, and into the vacuum hose;
- a hole through the center of the shroud body upper surface;
- and
- a mounting collar formed integrally with the shroud body upper surface and extending around said hole, the mounting collar being formed from a plurality of vertical collar sections, and wherein the collar sections may bend to move radially to thereby vary the size of the mounting collar.
A dust shroud for an angle grinder comprising:
- a body having an upper surface and a skirt extending downwardly from the upper surface;
- an opening formed in the center of the upper surface;
- a vacuum port connected to the upper surface;
- an attachment collar formed integrally with the upper surface of the body and extending around the opening, the attachment collar being divided into vertical attachment collar sections, the vertical sections being movable radially to vary the size of the attachment collar;
- and
- air passages disposed at the base of the attachment collar for allowing air into the dust shroud adjacent the output shaft of a grinder.
