Abstract
A bi-positional toothbrush comprising a brush head member (18) rotatably mounted to a handle (14) by a cylindrical pin (22) and coil spring (26) is described. The brush head member includes an array of bristles (42) at a forward end and terminates in an essentially flat angled surface (46) at a rearward end. The angled surface includes an axial bore (58) shaped to permanently constrain the forward end of the pin. The handle is elongated and includes at a forward end an essentially flat surface (70) angled at the same angle to the long axis of the handle as the angled flat surface of the brush head member is to its long axis. The angled flat surface of the handle includes an axial bore orthogonal thereto, sized to receive the pin and terminating in a means to rotatable secure the pin within the axial bore. The angled surfaces of the handle and brush head member includes symmetrical locking features (54, 86).
