Abstract

Abstract The method and apparatus for joining hair together utilizing ultrasonic vibrational energy in which the overlapping portions of the commercial hair and the live hair are maintained in fixed position to each other when the energy is introduced therein. The hair may be coated internally or externally with a thermoplastic material which acts as the bonding agent.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 37 words
A hand held instrument as claimed in claim 1, and further including positioning means associated with said supporting means to maintain said hairs in relatively fixed position to each other during the application of said ultrasonic vibrations.
Claim 2
Dependent Claim 20 words
A hand held instrument as claimed in claim 2, wherein said positioning means includes a slot on said supporting means.
Claim 3
Dependent Claim 29 words
A hand held instrument as claimed in claim 1, further including spring means yieldably urging said support means and transducer means for relative movement with respect to each other.
Claim 4
Dependent Claim 50 words
A hand held instrument as in claim 4, wherein said relative movement is to a position wherein said working and support surface are normally in engagement with each other under a predetermined static force, whereby said supporting and transducer means are first separated for the placement of the hairs therebetween.
Claim 5
Dependent Claim 75 words
A hand held instrument as claimed in claim 1, wherein a. said transducer means is contained in a housing, and b. said supporting means further includes a pair of spaced apart legs on opposite sides of said transducer housing in fixed spaced relation to each other with said gripping means extending from one end of said legs, and one of said legs at its opposite end terminating in a support arm containing said support surfaces.
Claim 6
Dependent Claim 275 words
A hand held instrument for joining together overlapping portions of supplemental hairs and existing hairs on top of the head comprising: a. supporting means having a surface for supporting the overlapping portions thereon, b. positioning means communicating with said supporting surface for retention of said overlapping portions in said overlapping relationship, c. a tool member having a working surface for contact with said overlapping portions, d. transducer means operative to vibrate said working surface of the tool member at a high frequency of at least 5,000 cycles per second, e. means for mounting said supporting means with respect to said transducer means in a manner to permit relative displacement of said working and supporting surface towards and away from each other for engagement with the opposite sides of the overlapping portions for applying a compressive force thereto, and , wherein said relative displacement is to a position wherein said working and support surfaces are normally in engagement with each other under a predetermined static force, whereby said supporting and transducer means are first separated for placement of the hairs therebetween, f. said tool member having a channel extending therein and terminating at one end of said working surface, means in communicating relation with said channel for supplying a bonding agent through said channel to one of said hairs in their area of overlap, said bonding agent becoming softened with the application of ultrasonic energy thereto and flowing from said tool onto said hair, and g. said supporting means includes means for gripping the instrument by the hand of the user to permit manual control of the relative displacement between said overlapping working and support surfaces.
Claim 7
Dependent Claim 33 words
A hand held instrument as claimed in claim 7, wherein said vibrations are applied in a direction substantially parallel to the direction in which the compressive force is applied to said overlapping portions.
Claim 8
Dependent Claim 29 words
A hand held instrument as claimed in claim 7, further including spring means yieldably urging said support means and transducer means for relative movement with respect to each other.
Claim 9
Dependent Claim 20 words
A hand held instrument as claimed in claim 7, wherein said positioning means includes a slot on said supporting means.
Claim 10
Dependent Claim 75 words
A hand held inStrument as claimed in claim 7, wherein a. said transducer means is contained in a housing, and b. said supporting means further includes a pair of spaced apart legs on opposite sides of said transducer housing in fixed spaced relation to each other with said gripping means extending from one end of said legs, and one of said legs at its opposite end terminating in a support arm containing said support surface.
