Abstract
A motorized broom that may be used in the game of curling is provided. The broom comprises a moveable synthetic fabric brush head that can provide a sweeping motion consistent with the regulatory requirements governing the game of curling. The motorized curling broom can assist individuals who would otherwise not be able to effectively accomplish a sweeping motion with their own strength or stamina to participate recreationally and competitively in the game. The curling broom comprises: a motor and associated gear reduction and crank configuration for causing a sinusoidal back and forth sweeping action of the brush head. The broom further includes a user control mechanism for intuitive adjustment of the power supplied to the brush head by way of controlling the speed of the motor and the pressure applied to the sweeping surface. A dynamic balancing mechanism reduces unwanted vibration transmitted to the individual using the broom.
