Abstract
A brush assembly is provided for increasing an effective area and uniformity of performance in an abrasive floor polishing application at a given size of brush mount. The brush assembly includes a pad with slots for receiving abrasive blades. The pad includes variable protrusions to provide varied support to the abrasive blades. The blades have a trapezoidal body shape. The blades include abrading components including an abrasive material such as diamonds. In some embodiments, the abrading components include a metallic material, such as copper material. In some embodiments, the abrading components include a phenolic material.
Claims15
An abrasive blade component for a brush assembly, the abrasive blade component comprising:
- a retainer portion having a top end, a longitudinally spaced distal end, and a trapezoidal body in between, the top end including outwardly extending protrusions configured to engage a slot of a brush pad, the trapezoidal body interfacing the top end with a top base side and the distal end with a bottom base side, the bottom base side being longer than the top base side, the retainer portion including two opposing leg sides extending in opposing lateral directions between the top and bottom base sides;
- and
- an abrading element coupled to the retainer portion at the distal end, the abrading element extending outside of the retainer portion and defining at least a portion of a longitudinal perimeter of the abrasive blade component.
An abrasive blade component for a brush assembly, the abrasive blade component comprising:
- a retainer portion having a top end, a longitudinally spaced apart distal end, and a body in between, the top end including outwardly extending protrusions configured to engage a slot of a brush pad, the body having a top base side and a bottom base side, wherein the body is trapezoidal in shape in lateral side view such that the bottom base side is longer than the top base side, the body including two opposing leg sides extending at least partly away from each other in opposing lateral directions between the top base side and the bottom base side;
- and
- an abrading element coupled to the retainer portion at the distal end, the abrading element extending outside of the retainer portion and defining at least a portion of a longitudinal perimeter of the abrasive blade component;
- wherein the body of the retainer has a first face spaced apart from a second face to define a thickness of the body portion, the first face being parallel to the second face.
A brush assembly, comprising:
- a substantially round pad including a bottom housing, the bottom housing having a plurality of slots, the plurality of slots being aligned along circumferentially spaced radial directions with respect to the pad, respectively, the bottom housing including a plurality of axially-extending variable protrusions extending from the body and aligned along circumferentially spaced radial directions, the plurality of axially-extending variable protrusions each having a peak end and a base end, the peak ends extending further axially away from the bottom housing than the respective base ends, the plurality of axially-extending variable protrusions each being disposed along one of the plurality of slots with the respective peak end at a radially outward position;
- and
- an abrasive blade component including:
- a retainer portion having a top end, a longitudinally spaced apart distal end, and a body in between, the top end including outwardly extending protrusions configured to engage a slot of a brush pad, the body having a top base side and a bottom base side, wherein the body is trapezoidal in shape in lateral side view such that the bottom base side is longer than the top base side, the body including two opposing leg sides extending at least partly away from each other in opposing lateral directions between the top base side and the bottom base side;
- and
- an abrading element coupled to the retainer portion at the distal end, the abrading element extending outside of the retainer portion and defining at least a portion of a longitudinal perimeter of the abrasive blade component;
- wherein the abrasive blade component is removably engaged on the pad at one of the slots with the abrasive blade component laterally oriented along the one of the slots and with the abrasive blade component circumferentially interfacing with one of the plurality of the axially-extending variable protrusions.
