Abstract
Abstract A thermal hair styling appliance includes interchangeable attachments, such as hair retaining clips, comb-brush clips or other types of attachments which are selectively attached to an operating button that is pivoted on a handle of the appliance. The appliance further includes a main electric heater which is controlled by a thermostat which, in turn, responds to a pair of auxiliary heaters. By selectively energizing the auxiliary heaters, the temperature of the main heater is controlled. A versatile hair styling appliance is thus provided. According to one embodiment, the operating button includes at least one projection which engages a slot in the end of the attachment being used. The attachment is held within the button by detents which engage other slots in the end of the attachment.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
329 words
A hair treating device comprising: a tubular barrel extending along an axis, said tubular barrel having first and second ends and defining a heating chamber therein; heating means disposed in said tubular barrel; vapor generating means disposed in said tubular barrel and energized by said heating means; a hair treating section of said tubular barrel along which heat and vapor are transmitted to the hair; a housing attached to said first end of the tubular barrel, said housing forming a handle; a readily detachable hair styling attachment cooperating with said tubular barrel in styling the hair, said attachment including a longitudinally extending open slot in one end thereof and a pair of notches disposed adjacent said one end of the attachment; an operating button; means for mounting said operating button in said handle and adjacent to the first end of said tubular barrel, said mounting means mounting said operating button to both slide and pivot relative to said handle and said tubular barrel; and coupling means included in said operating button for detachably securing said attachment thereto, wherein the coupling means includes: a land within said button; at least one projecting means extending from the land toward the tubular barrel, said projecting means including an enlarged head portion spaced from said land a distance greater than the thickness of the attachment; and a leaf spring retained on said projecting means by said head portion, wherein said leaf spring includes a pair of detents having oppositely sloping ramps which converge to an apex, and wherein said attachment is held between the leaf spring and the land with the projecting means received in the slot of the attachment and the apexes of the detents received in the notches of the attachment in order to detachably couple the attachment to the button, so that the attachment may be removed from the button by pulling the attachment away from the button and coupled to the button by pushing the attachment toward the button.
Claim 2
Dependent Claim
329 words
A hair treating device comprising: a tubular barrel extending along an axis, said tubular barrel having first and second ends and defining a heating chamber therein; heating means disposed in said tubular barrel; vapor generating means disposed in said tubular barrel and energized by said heating means; a hair treating section of said tubular barrel along which heat and vapor are transmitted to the hair; a housing attached to said first end of the tubular barrel, said housing forming a handle; a readily detachable hair styling attachment cooperating with said tubular barrel in styling the hair, said attachment including a longitudinally extending open slot in one end thereof and a pair of notches disposed adjacent said one end of the attachment; an operating button; means for mounting said operating button in said handle and adjacent to the first end of said tubular barrel, said mounting means mounting said operating button to both slide and pivot relative to said handle and said tubular barrel; and coupling means included in said operating button for detachably securing said attachment thereto, wherein the coupling means includes: a land within said button; at least one projecting means extending from the land toward the tubular barrel, said projecting means including an enlarged head portion spaced from said land a distance greater than the thickness of the attachment; and a leaf spring retained on said projecting means by said head portion, wherein said leaf spring includes a pair of detents having oppositely sloping ramps which converge to an apex, and wherein said attachment is held between the leaf spring and the land with the projecting means received in the slot of the attachment and the apexes of the detents received in the notches of the attachment in order to detachably couple the attachment to the button, so that the attachment may be removed from the button by pulling the attachment away from the button and coupled to the button by pushing the attachment toward the button.
Claim 3
Dependent Claim
34 words
The hair treating device of claim 1, wherein the projecting means including an enlarged head portion is a pair of headed screws arranged in tandem with respect to the axis of the tubular barrel.
Claim 4
Dependent Claim
39 words
The hair treating device of claim 2, wherein the leaf spring includes a lip projecting at an angle toward the barrel to guide the attachment between the leaf spring and land when the attachment is inserted into the button.
Claim 5
Dependent Claim
38 words
The hair treating device of claim 3, wherein the notches in the attachment open laterally outward and, wherein the detents on the leaf spring project laterally outward and are disposed between the screws which form the projecting means.
Claim 6
Dependent Claim
94 words
The hair treating device of claim 4, wherein the heating means is electrical and includes circuitry which comprises: a main heating element for producing heat to both treat hair and generate vapor; a thermostat in thermal conductive relation with said heater for controlling energization of said heater; auxiliary resistive heaters in thermal conductive contact with said thermostat; and means for selectively energizing said auxiliary heaters for causing said thermostat to react to the auxiliary heaters, as well as said main heater, so as to control the main heater by selectively activating the auxiliary heaters.
Claim 7
Dependent Claim
54 words
The hair treating device of claim 5, wherein there is a pair of auxiliary heaters disposed in contact with the thermostat, and wherein switch means are included so that the heaters may selectively be both energized, separately energized or not energized, in order to control the amount of heat generated by the main heater.
Claim 8
Dependent Claim
34 words
The hair treating device of claim 6, wherein the pair of auxiliary heaters and thermostat are held in contact by clip means which is, in turn, inserted into a cavity within the main heater.
Claim 9
Dependent Claim
36 words
The hair treating device of claim 5, wherein a fuse is connected in series with the thermostat, and wherein a neon lamp is connected in parallel across the circuit for indicating that the circuit is energized.
Claim 10
Dependent Claim
129 words
The hair treating device of claim 1, wherein the attachment is a clip which includes: an elongated portion which extends over said hair treating section; a base fixed to said elongated portion; a comb formed by a row of relatively rigid teeth projecting from said base along each side of said comb, wherein the individual tufts in the first row are aligned with spaces between every other tooth, wherein the individual tufts of the second row are aligned with spaces between the teeth not having an individual tuft from the first row of tufts aligned therewith and wherein said first and second row of individual tufts cooperate with said row of teeth to tension the hair just prior to winding the hair around the apparatus to form a curl.
Claim 11
Dependent Claim
34 words
The hair treating device of claim 9, wherein the elongated portion includes an annular portion which is slid over the tubular barrel to prevent the clip from pivoting with respect to the tubular barrel.
Claim 12
Dependent Claim
