ABSTRACT:
A coupler is disclosed for coupling floor maintenance pads to a driven pad disc. The coupler has one part for mounting on the driven disc and a second part which threads to the first part for holding and centering a maintenance pad to a disc. A lock arrangement is provided for preventing the coupler from becoming unthreaded during operation. The locking arrangement is formed by a detent mechanism. One part of the detent mechanism is formed on the first part and another cooperating part of the detent mechanism is formed on the second part. When the coupler parts are threaded together to secure a pad, the detent mechanism engages and provides a resisting force against unthreading. In another embodiment, wedge-shaped projections are formed on one part of the coupler for engaging a pad and resisting loosening.
