  • Patent number: 10350772
    Abstract: An electrically driven device provided with a housing, an electric motor with a drive shaft having a first rotary axis and a drive pin connected to the drive shaft eccentrically with respect to the rotary axis, and a driven shaft mounted in the housing for performing a pivoting is disclosed. The driven shaft is indirectly coupled to the drive shaft by means of a gear mechanism converting a rotary motion of the drive shaft into a reciprocating pivoting motion of the driven shaft. The gear mechanism comprises one intermediate shaft having a second rotary axis extending in the longitudinal direction of the intermediate shaft and at least one crank arm coupled to the drive pin. The crank arm is pivotably mounted in the housing and is coupled to the intermediate shaft thereby converting a rotary motion of the drive shaft into a reciprocating pivoting of the intermediate shaft about the second rotary axis.

  • Patent number: 10147918
    Abstract: A novel retarding mechanism is shown to reduce the inertia of the battery shell during a linear detachment movement from a handle of an appliance, such as a battery powered razor or shaver. The retarding mechanism is based on the interaction between the battery shell found on a lower portion of a razor handle and a battery carrier found within the upper portion of a razor handle. Specifically, an engagement spring having at least one knob type structure is mounted on an interior surface of the battery shell and axially engages protrusions and/or recesses on an exterior surface of the battery carrier during a detachment movement of the battery shell. During opening or detachment of the shell, the engagement of the knob with protrusions produces a retarding force effect of the shell during the linear detachment.
