Abstract
A cleaning device comprises a handle member and one or more brushes, each brush having an abrasive bristle end. Each brush is mounted on the handle member for independent pivotal movement relative to the handle member between an operative position in which the abrasive bristle end extends outwardly of the handle member for use and an inoperative position in which the abrasive bristle end is contained within the confines of the handle member for storage.
Claims4
A cleaning device comprising:
- a main body member having an interior pocket including an end wall, said main body member also having an open portion permitting access into said interior pocket;
- a first shaft adjacently located to said end wall and a second shaft in said interior pocket and spaced from said first shaft;
- a plurality of brushes, each of said brushes including an abrasive bristle end, an end portion oppositely spaced from said abrasive bristle end, each of said end portions being individually pivotally attached to said first shaft for permitting independent pivotal movement of said respective brush through said open portion between an inoperative position in which said respective abrasive bristle end is confined within said interior pocket and an operative position in which said respective abrasive bristle end extends outwardly of said main body member, and a stem portion intermediate each of said end portions and said respective abrasive bristle end;
- a cover member pivotally mounted on said second shaft for movement between a first position permitting pivotal movement of each of said abrasive bristle ends through said open portion and a second position preventing the pivotal movement;
- and
- wherein said end wall includes a plurality of slotted portions, the number of said slotted portions corresponding with the number of said brushes, each of said slotted portions being aligned with a respective one of said brushes and adapted to receive said respective stem portion when said respective brush is moved between said operative and inoperative positions, each of said slotted portions substantially limiting movement of said respective abrasive bristle end in a direction generally parallel to said first shaft when said respective brush is in said operative position.

A cleaning device comprising:
- a main body member having an interior pocket including an end wall, said main body also having an open portion permitting access into said interior pocket;
- a shaft located adjacent to said end wall;
- a plurality of brushes, each of said brushes including an abrasive portion, an end portion oppositely spaced from said abrasive portion, each of said end portions being independently pivotally attached to said shaft for permitting pivotal movement of said respective brush about said shaft and through said open portion between an inoperative position in which said respective abrasive portion is confined within said interior pocket and an operative position in which said respective abrasive portion extends outwardly of said end wall, and a stem portion intermediate each of said end portions and said respective abrasive portion;
- a cover member pivotally attached to said main body member and movable between a first position permitting pivotal movement of said abrasive portion through said open portion and a second position preventing the pivotal movement;
- and
- wherein said end wall includes a plurality of slotted portions, the number of said slotted portions corresponding with the number of said brushes, each of said slotted portions being aligned with a respective one of said brushes and adapted to receive said respective stem portion when said respective brush is moved between said operative and inoperative positions, each of said slotted portions substantially limiting movement of said respective abrasive portion in a direction generally parallel to said first shaft when said respective brush is in said operative position.

A cleaning device comprising:
- a main body member having an interior pocket including an end wall, said main body also having an open portion permitting access into said interior pocket;
- a shaft located adjacent to said end wall;
- a brush including a wire stem having an abrasive end portion and an end portion oppositely spaced from said abrasive end portion and bent around said shaft to form a pivotal connection therewith so that said brush is pivotally movable through said portion between an inoperative position in which said abrasive portion is confined within said interior pocket and an operative position in which said abrasive portion extends outwardly of said end wall;
- a cover member pivotally attached to said main body member and movable between a first position permitting pivotal movement of said abrasive portion through said open portion and a second position preventing the pivotal movement;
- and
- wherein said end wall includes a slotted portion adapted to slidably receive said wire stem when said brush is moved betweem said operative and inoperative positions, said slotted portion substantially limiting movement of said abrasive end in a direction generally parallel to said shaft when said brush is in said operative position.
