  • Publication number: 20100212096
    Abstract: A bracket assembly for use with cleaning implements such as push brooms has a handle connector for mounting a handle and a plate with a pair of depending flanges that are inserted into the broom head. The bracket assembly may be removably secured to the broom head with a fastener such as bolt and nut to provide an attachment mechanism having sufficient strength to withstand repeated sweeping motion. The removable bracket allows the arrangement of the handle and broom head to be reversed so that both faces of the broom head and bristles can be used interchangeably for sweeping. The removable bracket can be used with cleaning implements having heads of various dimensions and shapes.

  • Publication number: 20090165232
    Abstract: A mop with a handle includes a plurality of mop fibers coupled to the handle. The mop includes a grip mounted on the handle, and a collar that is slidably positioned on the handle. The collar can be secured to the grip when not in use. The collar may include one or more tabs with a ramp for engagement with a ridge located on the grip that, in operation, allows for detachably coupling of the collar to the grip. The ramp is configured so that it extends a sufficient distance from the tab so as to cause the tab to flex when the collar is attached to the grip. In operation, a user can uncouple the collar from the grip and slide the collar over the mop fibers and use the collar to wring the mop fibers.
