Broom with replaceable brush cartridge
View Patent ↗A broom with a replaceable brush cartridge is disclosed where the broom bristles can be replaced when worn. A brush cartridge is releasably retained by a broom head, and can be easily removed when needed. A replacement brush cartridge slides onto the broom head with a groove and track arrangement, and is locked into place with a wedge affixed to a live hinge on the brush cartridge that interacts with a wedge retainer on the broom head. A release tab moves the wedge away from the wedge retainer to unlock the brush cartridge from the broom head, allowing it to slide freely away. A new brush cartridge is then slid onto the track of the broom head, with the wedge and wedge retainer releasably engaging and locking the new brush cartridge to the broom head. The broom can be used as a pole broom or as a hand broom with a quick release retention button serving to release and reattach the pole as needed.
