Abstract
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.
Claims7
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.
