Abstract
A handle connector assembly for a rotatable brush head includes a receptacle formed in the handle and including a chamber with a plurality of sides that face radially inwardly and a compartment communicably interconnected to the chamber. A hub carried by the brush head includes a first locking lip that is received by the compartment. The receptacle has a second locking lip for lockably interengaging the first locking lip. The hub also includes a plurality of detents that are rotated through the chamber receptacle to selectively engage corresponding corners in the chamber and hold the brush head at a selected angular orientation relative to the handle.
Claims20
A connector assembly for rotatably attaching a brush head to a handle, said assembly comprising:
- a hub carried by one of the brush head and the handle, said hub being interengageable with a receptacle formed in the other of the handle and the brush head;
- said receptacle including a substantially polygonal chamber defined by an even number of discrete adjoining walls that surround and inwardly face a central axis of said receptacle;
- an even plurality of corners, each formed between a respective pair of said adjoining walls of said polygonal chamber such that said corners are arranged in opposing pairs about said polygonal chamber;
- said hub including a shaft inserted into said receptacle and an even number of positioning detents attached to and extending radially outwardly from said shaft within said polygonal chamber, said detents being arranged in one or more diametrically opposing pairs about said shaft and being interengageable with said walls of said chamber;
- said shaft further including a first gripping component for releasably connecting to a complementary second gripping component formed in said receptacle;
- whereby said brush head is rotated relative to said handle to drive said one or more opposing pairs of detents through said polygonal chamber and into interengagement with one or more selected pairs of said opposing corners of said polygonal chamber to hold the brush head at a selected angular orientation relative to the brush handle.
A rotatable brush head assembly comprising:
- a brush head having a plurality of bristles attached to and extending from one side thereof;
- a handle rotatably interengaged with said brush head;
- a hub carried by one of said brush head and the handle, said hub being interengageable with a receptacle formed in the other of said handle and said brush head;
- said receptacle including a substantially polygonal chamber defined by an even number of discrete adjoining walls that surround and inwardly face a central axis of said receptacle;
- an even plurality of corners, each formed between respective pairs of said adjoining walls of said polygonal chamber such that said corners are arranged in one or more opposing pairs about said polygonal chamber;
- said hub including a shaft received by said receptacle and an even number of positioning detents attached to and extending radially outwardly from said shaft within said polygonal chamber, said detents being arranged in one or more diametrically opposing pairs about said shaft and being interengageable with said walls of said chamber;
- said shaft further including a first gripping component for releasably connecting to a complementary second gripping component formed in said receptacle;
- whereby said brush head is rotated relative to said handle to drive said one or more opposing pairs of detents through said polygonal chamber into interengagement with one ore more selected pairs of said opposing corners of said polygonal chamber to hold said brush head at a selected angular orientation relative to said brush handle.
