Abstract

A hand held hair trimming device which when pulled through the hair cuts only a determined portion of the ends of hair strands while leaving adjacent hairs uncut. The device will cut a predetermined length off only the distal ends of the hair shafts each time it has the hair drawn through its serpentine channel. Angled encounter of the distal ends with the cutting blade is prevented by ridges and apertures encouraging such contact only at subtantially straight angles. The device may be held in either hand allowing the hair pass through in either direction by merely changing the rotational direction of the motor by moving the thumb switch. The blade section of the device may be adjustable for changing the amount of the determined length to be cut from the hair shafts or may be removable and replaceable with one of a plurality of differently configured blade assemblies thereby allowing for easy adjustment of the trimmed amount.

Claims19

Dependent claims

A hair trimming apparatus for trimming the distal ends of hair drawn therethrough, comprising:

a body assembly having a handle attached at one end and having a head mating end;
a motor mounted in said body assembly communicating with an electric power source;
a cutting head assembly mountable on said head mating end of said body assembly, said cutting head assembly having a face with a retainer cavity formed therein;
a slot located in said retainer cavity communicating with an interior cavity of said cutting head assembly;
an elongated hair retainer rotatably mounted at a first end and cooperatively engageable with said retainer cavity;
said elongated hair retainer having an operating position cooperatively engaged in said retainer cavity and having a raised position, disengaged from said retainer cavity;
an activating lever operatively engaged with said elongated hair retainer at said first end for moving said elongated hair retainer from said raised position to said operating position;
a cutter blade assembly operatively mounted in said interior cavity said cutter blade assembly having a cutting blade attached to a cutting frame, said cutter blade assembly operatively engaged with said motor when mounted in said interior cavity;
said elongated hair retainer when cooperatively engaged with said slot, forming a serpentine path for guiding hair strands through said cutting head assembly;
said slot allowing said distal ends of said hair strands drawn through said serpentine path to momentarily communicate through said slot into said interior cavity;
and
said cutting blade positioned in said interior cavity to cut portions off said distal ends of said hair strands communicating through said slot.

A hair trimming apparatus for trimming the distal ends of hair drawn therethrough, comprising:

a handle having a front face and a rear face;
a first side lobe attached to an upper end of said handle said first side lobe having a first front face and a first rear face;
a second side lobe, parallel to said first side lobe, attached to said upper end of said handle, said second side lobe having a second front face, and a second rear face;
a retainer cavity formed between said first side lobe and said second side lobe;
an elongated slot in said retainer cavity, said slot providing communication from the base of said slot to a cutting area between said first rear face and said second rear face;
an elongated hair retainer rotatably mounted at a first end to said upper end of said handle said elongated hair retainer cooperatively engageable with said retainer cavity;
said elongated hair retainer having an operating position cooperatively engaged in said retainer cavity and having a raised position, disengaged from said retainer cavity;
an activating lever operatively engaged with said elongated hair retainer for moving said elongated hair retainer from said raised position to said operating position;
said elongated hair retainer when cooperatively engaged with said slot, forming a serpentine path for guiding hair strands through said elongated slot and around said elongated hair retainer;
said slot allowing said distal ends of said hair strands drawn through said serpentine path to momentarily communicate through said slot into said cutting area;
a cutting assembly having a cutting blade operatively mounted in an interior cavity of said cutting assembly;
a motor operatively engaged with said cutting blade, said motor attached to said cutting assembly;
a cutting slot in a front face of said cutting assembly providing communicating with said cutting blade in said interior cavity;
means for registered engagement of said front face of said cutting assembly to said first rear face and said second rear face with said cutting slot in registered alignment with said elongated slot;
and
means to communicate electric power from said handle to said motor, whereby hair strands drawn through said serpentine path momentarily communicate through said elongated slot and into said cutting slot and said cutting blade removes a defined portion of the distal ends of said hair strands.
