  • Patent number: 10933547
    Abstract: A shaving handle system for holding a cartridge including a handle extending longitudinally along a longitudinal handle direction (L) between a distal end and a proximal end, and a connector adapted to rotate around a rocking axis (Z) with respect to the handle. The connector includes two lateral tongues extending forwardly from the proximal end of the handle, and the handle includes a deflecting means for flexing either one of the lateral tongues. The lateral tongues abut the deflecting means, such that when the connector is rotated in a first direction around the rocking axis (Z) with respect to the handle, one of the two lateral tongues is flexed by the deflecting means, and such that when the connector is rotated in a second direction around the rocking axis (Z) with respect to the handle, the other of the two lateral tongues is flexed by the deflecting means.

  • Publication number: 20200039098
    Abstract: A handle for a shaver comprising a handle body extending along a longitudinal axis of the handle; a connector for attaching a cartridge to the handle rotatable with respect to the handle body around a rotational axis perpendicular to the longitudinal axis; and an elastic tongue extending parallel with the longitudinal axis of the handle, when in a neutral position. The connector includes a cartridge end and a tongue end opposite to the cartridge end, the cartridge end of the connector being adapted to engage with the cartridge. The elastic tongue includes a first end and a second end. The first end of the elastic tongue is fixedly attached to or integral with the handle body. As the connector rotates the second end flexes towards a first extreme flexed position or a second extreme flexed position, the flexed elastic tongue biases the connector towards the rest position.
