Open the CIPO recordAbstract From the Canadian patent
A toothbrush handle with a hollow area through which a rotatable shaft passes has a soft rubber member surrounding the shaft. A thumb-operated gear ring is secured to the rubber and the assembly is disposed in a chamber of the handle so that the ring is accessible through an opening in the outer shell of the handle. The inner chamber surface has teeth which engage the teeth on the ring and maintain it in place when the ring is pressed to displace the rubber and attached ring against the chamber teeth which prevents the shaft from being rotated when a desired angular position of the handle and brush is achieved.
