Toothbrush with positionable stimulator tip.

摘要

Improved attachment structure between a rotatable interdental device (1) and a toothbrush handle (2) having said device (1) rotatable about a movable shaft (22). The device (1) is held in position by positioners (20) which engage when the device (1) is at a predetermined angle to said handle (2) and said shaft (22) is in a first position. The positioners (20) dissengage when the shaft (22) moves to a second position. The positioners (20) interact in a camming manner so that a predetermined force cams the shaft (22) into its second position. The shaft (22) extends from a resilient cantilever arm (23) which biases the shaft (22) toward the first position. The shaft (22) also includes diverging wedgelike end surfaces (25) which facilitate separating legs (16) of the device for assembly of the shaft (22) and device (1).
