Abstract

By providing a dual cutting head module which is constructed for precisely cutting beards and mustaches in a wide variety of alternate widths using one cutting blade, while also trimming and cutting nose/ear hair using a second cutting blade, an easily employed, dependable, reliable, multi-purpose beard/mustache and nose/ear hair trimming system is achieved. In one embodiment, the dual cutting blade head member is constructed for removable mounted engagement with the support base, as well as being arcuately pivotable relative thereto, enabling either of the two desired cutting blades to be moved into the operating position whenever desired by the user. In an alternate embodiment, the dual cutting blade head member is mounted to the support base for pivotable movement only, enabling the desired multi-purpose use and operation to be provided, with reduced simplicity in manufacturing.

Dependent claims

A beard and mustache trimmer system constructed for enabling separate cutting blade assemblies to be alternatively selected for use, said trimmer system comprising:

A. a support base incorporating a drive motor and an eccentrically mounted pin rotationally connected to the drive motor;
B. an upper housing
a. removably mountable to the support base,
b. incorporating a movable drive fork engageable with the eccentric pin for controlled movement thereof, and
c. comprising a holding zone constructed for supportingly retaining a dual cutting blade module/head member therein and enabling the dual cutting blade module/head member to be rotationally moved between its two alternate positions, said holding zone comprising two juxtaposed, spaced, facing surfaces, with at least one of said surfaces incorporating a support plate on which one side of said dual cutting blade module/head member is supportingly retained;
C. a dual cutting blade module or head member,
a. Incorporating a first cutting blade assembly at one end thereof and a second cutting blade assembly at the opposed end thereof, and
b. mounted to the upper housing for rotational movement relative thereto and for enabling the first cutting blade assembly to be positioned in an operative location, whenever desired, and also enabling the second cutting blade assembly to be rotated into the operative location, when desired;
whereby a beard and mustache trimmer system is achieved which provides two separate and independent cutting blade assemblies, for use by a consumer, whenever desired, in order to achieve a particular cutting effect or result.
