Abstract
Abstract A dust mop assembly including an upper mop head which has formed in its lower surface a continuous, peripheral, downwardly open groove. A retainer ring inserts upwardly into the groove and medially secures therewithin a plurality of yarns of suitable size for dusting purposes. In preferred embodiment, a plurality of spaced fingers project downwardly into the groove both to provide adequate clearance for yarn positioning and to secure the retainer ring to the mop head in a manner to cinch and retain the mop yarns therebetween. An elongated socket is integrally formed in the top of the mop head to receive therein a socket portion of an operating handle in a swivel connection.
