  • Patent number: 10843357
    Abstract: A razor handle assembly includes a connector which is detachably coupled to a razor cartridge; a razor handle which is elongated along a longitudinal axis and coupled to the connector such that the connector is capable of pivoting about a rotation axis perpendicular to both the longitudinal axis and a transverse axis along which the razor cartridge is elongated, the transverse axis being perpendicular to the longitudinal axis; and an elastic member having a first end engaged with a first fixing portion formed in the connector and a second end engaged with a second fixing portion formed in the razor handle. When the connector pivots about the rotation axis with respect to the razor handle, the elastic member is deformed to provide a restoring force that causes the connector to return to a neutral position at which the transverse axis is perpendicular to the longitudinal axis.
