Quick coupler for mounting a rotational disk
First Claim
1. A quick coupler for mounting a rotational disk comprising:
- a disk holder of a ring shape having a center aperture formed in a polygon, each side of the polygon being provided with a spring-loaded steel ball and a recessed slot behind each ball adapted for receiving a jutting key situated on and operated by a retractable ring attached to a travel housing, said disk holder being further provided with a planar surface for releasably engaging a rotational disk thereon by mechanical means; and
a travel housing of cylindrical shape having a first end threaded for engaging a drive means and a second end in said polygon shape for intimately engaging said center aperture of said disk holder for transmitting a rotational motion of said drive means, said second end being further provided with a spring-loaded retractable ring for sliding in a longitudinal direction of said travel housing and for operating a plurality of jutting keys attached thereon such that when said second end being pushed into said center aperture of the disk holder each of said plurality of jutting keys engages one of said steel balls by pushing the balls radially inward in a locked position into a hemispherical recess provided in a flat surface of said polygon-shaped second end of the travel housing.

Abstract
A quick coupler for mounting a rotational disk which enables the rotational disk to be quick connect to or disconnect from a pad conditioner disk holder is disclosed. The quick coupler consists of two major components of a disk holder and a travel housing. The disk holder is formed in a ring shape having a center aperture in a polygon shape for intimately engaging a polygon-shaped shaft of the travel housing such that a rotational torque can be transmitted from the travel housing to the disk holder. Each side of the polygon is provided with a steel ball and a recessed slot behind the ball for receiving a jutting key operated by a retractable ring attached to the travel housing. The travel housing is formed in a cylindrical shape that has a first end threaded for engaging a drive means and a second end in the polygon shape.
