Patent

CA 2120871

An interdental toothbrush has a hinged locking retainer on the end of an elongated handle for capturing the stem of a twisted wire brush. The locking retainer has a hole which is adapted to receive the stem of a twisted wire brush. A land is formed in the handle adjacent the groove so that the wire brush stem is captured between that land area and a land area on the retainer. A latch on the locking retainer has a top end with a double cam surface thereon. One of the camsurfaces guides the latch into a locking position as the retainer is closed. Theother of the cam surfaces releases the locking retainer when pushed.

La présente invention se rapporte à une brosse interdentaire comportant, à l'extrémité d'un manche allongé, un dispositif articulé verrouillable pour retenir la tige d'une brosse à fils torsadés. Le dispositif de retenue est percé d'un trou dans lequel s'insère la tige de la brosse. Le manche comporte une portion plate adjacente à la rainure de manière à ce que la tige de la brosse s'insère entre cette portion et une portion plate sur le dispositif de retenue, lequel est muni d'un verrou ayant sur le dessus une surface de came double. L'une des surfaces de came sert à guider le verrou dans la position verrouillée lorsque le dispositif de retenue est fermé. Lorsqu'elle est poussée, l'autre surface de came déverrouille le dispositif de retenue.
