Abstract

See full text

A broom has a handle, a broom head, a bracket for securing the handle against rotation, and a plug for securing the bracket to the broom head. The handle has a segmented locking section near its mounting end, and can be attached to either of two opposed apertures in the broom head. The bracket has a pair of spaced-apart arms with locking faces that can engage the faces on the locking section. To enable the locking faces to engage onto the locking section from a radial direction, the open ends of the locking arms are spaced apart by a distance at least equal to the minor chord of the locking section. The bracket also has a locking aperture that allows it to be secured to the broom head by fastening the plug to the unused opposed aperture.
