Drive system for beard and mustache trimmer
View Patent ↗By providing a beard and mustache trimmer construction wherein a single motor driven element is employed for directly operating both the main cutting blades as well as a pop-up trimmer, an easily employed, efficient, beard and mustache trimmer is realized. The trimmer is constructed in a manner which enables the pop-up trimmer to be directly driven by the same element which drives the principal cutting blades. In this way, greater power is delivered to the pop-up trimmer element than has otherwise been attained with prior art systems as well as providing substantially reduced noise levels. As a result, a substantially enhanced cutting and trimming system is realized.
1. A hair cutting and trimming system constructed for providing cutting of any desired hair length, said cutting and trimming system comprising:
A. a housing;
B. a first hair cutting blade fixedly mounted to the housing;
C. a second hair cutting blade movably mounted to the housing in cooperating association with the first hair cutting blade for producing hair cutting action therewith;
D. a movement control member
a. comprising two finger members positioned in juxtaposed, spaced, cooperating relationship with each other, defining a spaced zone therebetween, and
b. mounted to said second movable hair cutting blade for causing said second hair cutting blade to reciprocatingly move in a side to side manner relative to the first hair cutting blade;
E. drive means
a. mounted in said housing in cooperating association with the movement control member for continuously driving the movement control member whenever the drive means is activated, and
b. comprising a rotationally driven eccentrically mounted pin positioned for engagement in said spaced zone formed between the two finger members;
F. a hair trimming assembly constructed for providing fine or detailed trimming of specific areas, said hair trimming assembly
a. being mounted to the housing,
b. movable between a first OFF position and a second ON position,
c. comprising a pair of hair trimming blades, the first of said pair of hair trimming blades being fixedly mounted and the second of said pair of hair trimming blades being movably mounted in cooperating relationship with the first hair trimming blade, and
d. a separate and independent pivot arm pivotally mounted to the hair trimming assembly, said pivot arm being
1). secured at a first end to the second, movable hair trimming blade for controllably moving the second hair trimming blade in the desired side to side reciprocating manner, and
2). positioned for engaging the spaced zone between the two finger members of the movement control member with a second end thereof when the hair trimming assembly is in its second, ON position, and said second end being disengaged from the movement control member when the hair trimming assembly is in its first, OFF position;
whereby the single rotational movement of the eccentrically mounted pin simultaneously directly drives both the movement control member and the pivot arm whenever the hair trimming assembly is in its second ON position.
2. The hair cutting and trimming system defined in claim 1 , wherein the hair trimming assembly comprises a support panel pivotally mounted to the housing and movable between said first OFF position and said second ON position.
3. The hair cutting and trimming system defined in claim 2 , wherein said first and second hair trimming blades are mounted to the support panel for being stowed and non-usable when the panel is in its first position and being positioned for use whenever the panel is in its second position with said pivot arm being engaged with the movement control member for causing the second hair trimming blade to be operational.
4. The hair cutting and trimming system defined in claim 3 , wherein said pivot arm is further defined as comprising
3). an elongated shaft pivotally mounted to the panel with a pivot axis formed in the central zone thereof,
4). a first end of said shaft being fixedly mounted to the second, movable, hair trimming blade, and
5). a second end of said shaft being movably positionable between engagement in the spaced zone formed between the two finger members of the movement control member, when said panel is in its second position, and disengagement from the spaced zone whenever the panel is in its first position.
5. The hair cutting and trimming system defined in claim 3 , wherein said movement control member is further defined as extending from the second hair cutting blade and comprising an enlarged receiving zone position for cooperating, engaged association with the drive means and one end of the pivot arm when said pivot arm is in its second position.
6. The hair cutting and trimming system defined in claim 3 , wherein the movement of the support panel is controlled by the movement of a finger operatable button.
7. The hair cutting and trimming system defined in claim 3 , wherein the pair of hair trimming blades formed in the hair trimming assembly each comprise an overall width substantially smaller than the overall width of the first and second hair cutting blades for enabling smaller, limited, more detailed cutting of any desired area.
