Abstract
A cleaning brush comprises a brush body rotatably mounted on and biased axially towards a brush holder by a compression spring, a post non-rotatable on the brush body and projecting axially towards the brush holder, a sleeve mounted on the posts for rotation relative thereto and non-rotatable relative to the brush holder, and an actuating lever for displacing the sleeve axially away from the brush holder. The post has a circumferentially extending slot engaged by a pair of opposed inwardly projecting pins of the sleeve to provide a camming arrangement such that operation of the lever to move the sleeve axially away from the brush holder causes rotation of the brush body. The brush body is rotatable through 180.degree. from one brushing position to another brushing position.
Claims14
A cleaning brush comprising:
- a brush body having a post fixed thereto and extending substantially perpendicularly therefrom;
- a brush holder;
- means mounting said brush body on said brush holder for rotation with respect thereto around the axis of said post, said mounting means including means for resiliently biasing said brush body toward said brush holder;
- a sleeve mounted on the post for rotation relative thereto and non-rotatable relative to the brush holder;
- actuation means for displacing the sleeve axially away from the brush holder;
- the post and the sleeve being in camming engagement such that operation of the actuation means to move the sleeve axially away from the brush holder causes rotation of the brush body;
- and
- the engagement between the post and the sleeve being such that return of the sleeve towards the brush holder is permitted without rotation of the sleeve relative thereto.
A brushing device comprising:
- a brush body having a post fixed thereto and extending substantially perpendicularly therefrom;
- a brush holder;
- means mounting said brush body on said brush holder for rotation with respect thereto around the axis of said post, said mounting means including means for resiliently biasing said brush body toward said brush holder;
- a sleeve;
- means mounting said sleeve for non-rotational translational displacement toward and away from said brush holder;
- actuatable means for displacing said sleeve away from said brush holder;
- camming means coupling said sleeve and post for rotating said post in response to said sleeve being displaced away from said brush holder;
- and wherein
- said resilient biasing means acts on said post to displace said sleeve back toward said brush holder and rotate said post relative to said sleeve.
