Abstract
A coupler is disclosed for coupling floor maintenance pads to a pad driven disc. The coupler has one part which is mounted to or from an integral part of the driver disc and a second part which snaps onto the first part for holding and centering a maintenance pad to a disc. A spring lock arrangement is provided for preventing the coupler from separating and comprises a spring clip carried by the retainer engageable with recesses formed on an axially extending locking post forming part of the base part. The spring clip is held to the retainer by a pair of keepers which define slots having diverging cross-sections. The spring clips include a pair of elongate legs interconnected by a bridging segment on one end and a pair of finger engageable pressure pads on opposite ends by which the spring clip is squeezed to spread apart the legs. Both the retainer and base include fluid supply openings through which floor treating fluids can be dispensed onto the floor. Alternate embodiments are also disclosed which include multi-stepped locking posts.
