Abstract:
1. A mop assembly comprising: a stick with an opening defined in a lower end thereof to securely receive therein a substantially Y-shaped connector having therein a neck to be inserted into the opening of the stick, a cutout defined in a distal end of the connector and a channel defined through the connector to communicate with the cutout and to receive therein a stop abutted to a bottom periphery defining the channel, a ball seat with an arcuate face, a spring sandwiched between the stop and the ball seat and a ball received in the arcuate face of the ball seat; a pivoting head having a base and a sectorial extension extending upward from the base to be securely received in the cutout of the connector via a pin which extends through an outer periphery of the cutout and the sectorial extension and having a positioning recess defined in a periphery of the sectorial extension to receive therein the ball; a disk combination having a covering disk provided with a recessed area defined in a top face of the covering disk to receive therein the base of the pivoting head and a receiving space defined in a bottom face of the covering disk and an engaging disk securely engaged with the covering disk and having multiple cleaning elements extending from a bottom face of the engaging disk; a securing disk having a first disk on top of the base of the connector to securely sandwich the base of the pivoting head with the covering disk and a second disk securely attached to the bottom face of the covering disk and connected to the first disk via securing elements such that the base of the pivoting head is able to freely rotate relative to the disk combination; and a bearing assembly having a annular pad provided between the bottom face defining the recessed area of the covering disk and the base of the pivoting head and a pressing pad sandwiched between the base of the pivoting head and the first disk so as to prevent direct friction between the base of the pivoting head and the covering disk such that the connector is able to pivot relative to the pivoting head and the disk combination is able to freely rotate relative to the pivoting head.
