Patent number: 10933547Abstract: 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.Type: GrantFiled: January 10, 2018Date of Patent: March 2, 2021Assignee: BIC-VIOLEX SAInventors: Panagiotis Kopelas, Dimitrios Efthimiadis
