Abstract

See full text

A quick release attachment for a power tool having a rotatable spindle includes a pad assembly and a quick release connector adapted to join the pad assembly to the spindle. The pad assembly includes a mounting plate and a pad affixed to at least one side of the mounting plate, wherein the pad includes a primary material that is either metal, stone, ceramic, fiber, sand, nylon or polypropylene, and the mounting plate includes a central aperture. The mounting plate aperture further comprises a circular ring disposed therein and has a t-shaped key extending diametrically across the aperture. The t-shaped key comprises a magnetically attractive material. The quick release connector has a main body adapted to fixedly engage the spindle. The connector further has a head end extending from the main body and having a circular cross-section sized to engage the circular ring. The head end further has a slot sized to engage the t-shaped key. The slot further comprises a distal portion extending axially along the head end, a proximal portion extending axially along the head end offset from the distal portion, and a transition portion joining the distal and proximal portions. The main body further comprises a permanent magnet disposed therein having at least one surface adjacent to the proximal portion of the slot. The pad assembly is selectively affixed to the quick release connector by manipulating the head end into the aperture and moving the t-shaped key through the slot until reaching the proximal portion, whereupon the t-shaped key is retained by the magnetic attraction of the permanent magnet.
