Abstract: The present invention relates to a toothbrush apparatus having multiple rotatable brushing systems, including a body onto which a head (1) is attached, wherein said head is provided with adjacent counter-rotating brushes (2, 2?) having an overall cylindrical outer shape and longitudinal axes that parallel to one another, each brush (2, 2?) being rotated by a shaft (4, 4?) and supported at each of the ends thereof by a bearing (3, 3?, 5, 5?) forming part of a holder (6) which defines the distance between the longitudinal axes of said brushes, said holder (6) including at least two flexible arms (6a, 6b, 6c, 6d) oriented substantially perpendicular to said longitudinal axes, such that the respective ends thereof form said bearings, said flexible arms being connected to a base (6e) capable of ensuring the attachment of said holder (6) onto the head (1).

Abstract: The invention relates to a mechanical toothbrush with a dual rotary brushing system having a handle and a head fixed on the handle. The head is provided with adjacent contrarotating brushes that are of cylindrical shape and have substantially parallel axes, each of them being supported at least at their distal end by a bearing and each being driven by a shaft. The shafts are flexible and supported by the two bearings to allow the two brushes to move away from and towards each other. The support includes four flexible branches around a central component serving to fix the support on the head composed of a single arm. The support and/or the head of the toothbrush are designed such that the support is fixed on the head while allowing the support to pivot about its point of fixation to the head.

Abstract: The present invention provides a mechanical toothbrush with a dual rotary brushing system and comprising a handle-forming body and a head fixed to the handle, which head is provided with two adjacent contra-rotating brushes of cylindrical shape and having substantially parallel axes. Each of the two brushes is driven by a flexible shaft situated in the head and supported, at least at its distal end, by a respective bearing mounted on a support that enables the two brushes to move apart one away from the other, then urging the brushes towards the other by a return effect.
