Definitions
- the present invention is directed to a hair curling device, and more particularly to a hair curling device with a hair clamp for curling hair as well as a negative ion generator for imparting negative ions to the curled hairs.
- negative ions to hairs is known to be effective to give a well finished hair styling.
- the negative ions are widely recognized in the filed of air purification or environmental improvement to denote negatively charged airborne molecules mostly combined with moisture.
- One typical example is a hair dryer in which the negative ions are applied to the hairs being heat-treated for supplementing the hair with moisture carried on the negative ions, in addition to neutralizing the positively-charged hairs.
- the hair dryer is preferably designed to emit the negate ions relatively free from a hot shot of air blow in order to deliver the negative ions to the hairs without being deteriorated or collapsed by the heat.
- the heat problem has to be considered when giving the effect of the negative ions to a hair curling device that applies a considerable amount of heat directly to the hair intended to be curled. This is particularly true for the curling device with a hair clamp, as disclosed in U.S. Patent No. 5, 243, 694 in which the hair clamp is placed over a heated barrel to clamp the hair therebetween for curling the hair by application of considerable amount of heat.
- WO 03/061425 A1 proposes a hair iron device provided with a negative ion generator which emits the negative ions towards the volume of hair adjacent but not covered by a hair clamp.
- one or more negative ion generators are located on the heating barrel at portions offset laterally from the hair clamp with respect to an axis of the barrel for emitting the negative ions generally in radial directions of the barrel towards the hair out of the hair clamp.
- the negative ion generator is normally limited to give a small range or emission cone within which the negative ions propagate relative to an effective axial length of the barrel, i.e., the width of the strand of hair wound around the barrel, it is difficult to cover the full length of the barrel with a single negative ion generator on one side of the barrel. In other words, the single ion generator is not sufficient to give the negative ion bombardment to the hair over the entire length of the barrel. Further, since the ion generators are mounted on the barrel itself, the addition of the ion generators within the length of the barrel will certainly lead to an increased bulk and complexity of the barrel.
- the hair curling device in accordance with the present invention includes a hand grip, and a heating barrel extending from the hand grip to have a lengthwise axis.
- the heating barrel is configured to wind user's hair therearound and to have a rounded curling surface on a part of its circumference.
- a hair clamp is held by the hand grip to be moveable between a clamping position of clamping the hair on the curling surface and a release position of releasing the hair from the curling surface.
- the hair clamp is curved in match with the curling surface in order to curl the hair clamped between the hair lamp and the barrel.
- the device further includes at feast one negative ion generator with an ion port for emitting negative ions.
- the negative ion generator is configured to give a cone emission axis along which the negative ions are emitted through the ion port in an emission cone.
- the ion port is located at a portion offset axially from the barrel as well as offset circumferentially from the hair clamp with the cone emission axis being oriented in such a direction that the emission cone extends mainly along the axial of the barrel to cover a region outwardly of the curling surface of the barrel, i.e., the hair clamp.
- the negative ion generator can emit the negative ions in a concentrated manner over the length of the barrel to the hair just out of the hair clamp for adding the negative ion treatment effect to the curled hair.
- the negative ion generator is mounted on the hand grip adjacent to the barrel with the cone emission axis oriented radially outwardly of the barrel at an inclination angle of less than 45° with respect to the axis of the barrel within a horizontal plane which is perpendicular to a vertical plane including a width center of the hair clamp and the axis of the barrel. Accordingly, the optimal negative ion treatment is expected, in addition to that the barrel can be free from mounting the negative ion generator and therefore can be made into a simple and compact structure for curling the hair.
- the two negative ion generators may be mounted around the hand grip in a generally diametrically opposite relation to each other so as to apply the negative ions to the hair on both sides of the hair clamp.
- the ion port is preferred to be spaced radially outwardly of the circumference of the barrel for directing the negative ions effectively to the volume of hair around the barrel out of the hair clamp.
- the heating barrel may be provided with an end cap at its axial end opposite to the hand grip.
- the negative ion generator may be mounted either solely on the end cap or both on the end cap and the hand grip for emitting the negative ions on the hairs over the length of the barrel.
- the heading barrel may be composed of a first barrel half and a second barrel half each shaped to have a semi-circular cross section with a top rounded outer surface and a flat straightening surface.
- the top rounded surface of the first barrel half defines the curling surface.
- the hand grip is composed of a first grip half and a second grip half which support the first barrel half and the second half barrel, respectively.
- the first and second grip halves are pivotally connected to each other so as to move the first barrel half between a closed position of keeping the respective flat straightening surfaces in a closely adjacent relation for straightening the hairs entrapped therebetween and an open position of releasing the hair.

- the negative ion generator is arranged such that the emission cone is intersected by a mating plane defined between the straightening surfaces in the closed position of the barrel so as to cover a region immediately outwardly of the straightening surfaces.
- the two negative ion generators are preferred to be mounted on opposite sides of the first grip half. Further, additional negative ion generator or generators are mounted on the second grip half to give a like emission cone which coves the region in an overlapping relation with the emission cone provided by the negative ion generator on the first second grip half.
- the hair curling device includes a hand grip 10 , a heating barrel 20 extending coaxially from one axial end of the hand grip 10 to have a lengthwise axis, and a hair clamp 30 supported to the hand grip 10 for clamping user's hair on a portion of the heating barrel 20 .

Abstract
Description
- The present invention is directed to a hair curling device, and more particularly to a hair curling device with a hair clamp for curling hair as well as a negative ion generator for imparting negative ions to the curled hairs.
- Application of negative ions to hairs is known to be effective to give a well finished hair styling. The negative ions are widely recognized in the filed of air purification or environmental improvement to denote negatively charged airborne molecules mostly combined with moisture. One typical example is a hair dryer in which the negative ions are applied to the hairs being heat-treated for supplementing the hair with moisture carried on the negative ions, in addition to neutralizing the positively-charged hairs. For effectively applying the negative ions, the hair dryer is preferably designed to emit the negate ions relatively free from a hot shot of air blow in order to deliver the negative ions to the hairs without being deteriorated or collapsed by the heat. Therefore, the heat problem has to be considered when giving the effect of the negative ions to a hair curling device that applies a considerable amount of heat directly to the hair intended to be curled. This is particularly true for the curling device with a hair clamp, as disclosed in U.S. Patent No. 5, 243, 694 in which the hair clamp is placed over a heated barrel to clamp the hair therebetween for curling the hair by application of considerable amount of heat.
- WO 03/061425 A1 proposes a hair iron device provided with a negative ion generator which emits the negative ions towards the volume of hair adjacent but not covered by a hair clamp. In the device, one or more negative ion generators are located on the heating barrel at portions offset laterally from the hair clamp with respect to an axis of the barrel for emitting the negative ions generally in radial directions of the barrel towards the hair out of the hair clamp. However, since the negative ion generator is normally limited to give a small range or emission cone within which the negative ions propagate relative to an effective axial length of the barrel, i.e., the width of the strand of hair wound around the barrel, it is difficult to cover the full length of the barrel with a single negative ion generator on one side of the barrel. In other words, the single ion generator is not sufficient to give the negative ion bombardment to the hair over the entire length of the barrel. Further, since the ion generators are mounted on the barrel itself, the addition of the ion generators within the length of the barrel will certainly lead to an increased bulk and complexity of the barrel.
- In view of the above insufficiency, the present invention has been accomplished to provide an improved hair curling device which is capable of effectively applying the negative ions to hairs with a simplified arrangement of negative ion generator. The hair curling device in accordance with the present invention includes a hand grip, and a heating barrel extending from the hand grip to have a lengthwise axis. The heating barrel is configured to wind user's hair therearound and to have a rounded curling surface on a part of its circumference. A hair clamp is held by the hand grip to be moveable between a clamping position of clamping the hair on the curling surface and a release position of releasing the hair from the curling surface. The hair clamp is curved in match with the curling surface in order to curl the hair clamped between the hair lamp and the barrel. The device further includes at feast one negative ion generator with an ion port for emitting negative ions. The negative ion generator is configured to give a cone emission axis along which the negative ions are emitted through the ion port in an emission cone. The ion port is located at a portion offset axially from the barrel as well as offset circumferentially from the hair clamp with the cone emission axis being oriented in such a direction that the emission cone extends mainly along the axial of the barrel to cover a region outwardly of the curling surface of the barrel, i.e., the hair clamp. Thus, the negative ion generator can emit the negative ions in a concentrated manner over the length of the barrel to the hair just out of the hair clamp for adding the negative ion treatment effect to the curled hair.
- Preferably, the negative ion generator is mounted on the hand grip adjacent to the barrel with the cone emission axis oriented radially outwardly of the barrel at an inclination angle of less than 45° with respect to the axis of the barrel within a horizontal plane which is perpendicular to a vertical plane including a width center of the hair clamp and the axis of the barrel. Accordingly, the optimal negative ion treatment is expected, in addition to that the barrel can be free from mounting the negative ion generator and therefore can be made into a simple and compact structure for curling the hair.
- Further, the two negative ion generators may be mounted around the hand grip in a generally diametrically opposite relation to each other so as to apply the negative ions to the hair on both sides of the hair clamp.
- In this connection, the ion port is preferred to be spaced radially outwardly of the circumference of the barrel for directing the negative ions effectively to the volume of hair around the barrel out of the hair clamp.
- The heating barrel may be provided with an end cap at its axial end opposite to the hand grip. In this case, the negative ion generator may be mounted either solely on the end cap or both on the end cap and the hand grip for emitting the negative ions on the hairs over the length of the barrel.
- Further, the heading barrel may be composed of a first barrel half and a second barrel half each shaped to have a semi-circular cross section with a top rounded outer surface and a flat straightening surface. In this case, the top rounded surface of the first barrel half defines the curling surface. Likewise, the hand grip is composed of a first grip half and a second grip half which support the first barrel half and the second half barrel, respectively. The first and second grip halves are pivotally connected to each other so as to move the first barrel half between a closed position of keeping the respective flat straightening surfaces in a closely adjacent relation for straightening the hairs entrapped therebetween and an open position of releasing the hair. The first grip half is configured to carry the hair clamp as well as the negative ion generator. The negative ion generator is arranged such that the emission cone is intersected by a mating plane defined between the straightening surfaces in the closed position of the barrel so as to cover a region immediately outwardly of the straightening surfaces. Thus, the hairs just out of the flat straightening surfaces can successfully receive a considerable amount of the negative ions so as to be treated therewith over the length of the barrel for optimal hair straightening finish. The two negative ion generators are preferred to be mounted on opposite sides of the first grip half. Further, additional negative ion generator or generators are mounted on the second grip half to give a like emission cone which coves the region in an overlapping relation with the emission cone provided by the negative ion generator on the first second grip half.

- Now referring to FIGS. 1 to 4, there is shown a hair curling device in accordance with a preferred embodiment of the present invention. The hair curling device includes a
hand grip 10, aheating barrel 20 extending coaxially from one axial end of thehand grip 10 to have a lengthwise axis, and ahair clamp 30 supported to thehand grip 10 for clamping user's hair on a portion of theheating barrel 20. Theheating barrel 20 is made of a metal cylinder and incorporates anelectric heater 40 for heating the entire circumference of the barrel. Thehair clamp 30 is composed of a metal-madetongue 34 extending substantially the full length of thebarrel 20 and ahandle 36 holding the one end of thetongue 34. Thehandle 36 includes apivot 38 which is supported to thehand grip 10 adjacent to the axial end of the barrel so that thehair clamp 30 is movable between a clamping position where thetongue 34 is placed over the peripheral portion of thebarrel 20 for clamping the hair therebetween and a release position where thetongue 34 is away from the barrel for releasing the hair. Abias spring 39 is provided inside of thehandle 36 to urge the hair clamp towards to the clamping position. Thetongue 34 is curved in conformity with the portion of the circumference of thebarrel 20 to clamp the hair around the portion of the barrel for curling the hair. In this sense, the curved portion of thebarrel 20 is defined as acurling surface 24. - An
end cap 50 is provided at the distal axial end of thebarrel 20 to constitute a water tank holding a volume of water which is supplied for contact with theheater 40 to thereby generate steam that is discharged through a plurality of vents formed in thebarrel 20 to the clamped hair. Thetongue 34 of theclamp 30 is formed with escape holes 35 in staggered relation to the vents for escaping the steam. - The
hand grip 10 is also configured to mount twonegative ion generators 60 at its one end adjacent to thebarrel 20 for spraying negative ions to the hairs being clamped for curling, particularly to the volume of hair out of thehair clamp 30, i.e., the curlingsurface 24 of thebarrel 20 in order to give smoothed finish to the curled hair. Aswitch 14 is provided on thehand grip 10 to heat thebarrel 20 with activating or deactivating the negative ion generators. - As shown in FIGS. 5 to 8, the
negative ion generator 60 includes adielectric base 62 carrying aneedle electrode 70 and aground electrode 74, and adielectric cover 80 which is assembled to the base to form a shell concealing therein theelectrodes needle electrode 70 has a pointed tip at its front end and is provided at its rear end with avoltage terminal 71 for connection with awire 72 leading to a voltage output of a highvoltage generating circuit 90 accommodated within thegrip 10. Theneedle electrode 70 extends along the length of the base 62 with its pointed tip receded from the front edge of thebase 62. Theground electrode 74 is disposed at the front end of the base 62 in a forwardly spaced relation to the pointed tip of theneedle electrode 70 and is provided with aground terminal 75 for connection with aground wire 76 leading to a ground of the highvoltage generating circuit 90. As shown in FIG. 6, the highvoltage generating circuit 90 applies a high voltage, for example, - 5 kV to theneedle electrode 70 relative to theground electrode 74, thereby developing the corona discharge between the electrodes to negatively charge the particles present in the surrounding air for generating negatively charged ions around the pointed tip of theneedle electrode 70. The negative ions are attracted towards theground electrode 74 to move in a forward direction past theground electrode 74 and is caused to emit through anion port 82 formed in the front end of thecover 80. Thus, the negative ions are forced out through theion port 82 and directed along a cone emission axis (E) to emit within an emission cone having a cone angle (γ) of about 30° to 100°, as shown in FIGS. 1 and 2. Although not shown in the figures, thenegative ion generator 60 may be configured to incorporate a fan which gives an additional force for emitting the negative ions out through the ion port. - The
negative ion generators 60 thus configured are mounted on thehand grip 10 at portions offset axially from thebarrel 20, as shown in FIGS. 1 and 2, and offset circumferentially from thehair clamp 30, as shown in FIG. 4, in order to emit the negative ions mainly along the axial length of thebarrel 20 towards regions on opposite sides of thehair clamp 30 or the curlingsurface 24. Also, theion port 82 is offset radially outwardly by a distance (D) of 5 to 20 mm from the circumference of thebarrel 20 and is oriented radially outwardly of thebarrel 20 to have the cone emission axis (E) inclined at an angle () of 10° to 45° with respect to the axis of thebarrel 20 within a horizontal plane, as shown in FIGS. 1 and 4. The horizontal plane is defined as a plane in which the twonegative ion generators 60 are disposed or a plane perpendicular to a vertical plane passing through a width center of thetongue 34 of thehair clamp 30 and through the axis of thebarrel 20. As shown in FIG. 2, the cone emission axis is approximately aligned with the axis of thebarrel 20 within the vertical plane. Thus, the emission cone covers the region immediately outwardly ofbarrel 20, particularly outwardly of the curlingsurface 24 and thehair clamp 30, assuring to spray the negative ions over the hair out of thetongue 34 of theclamp 30 along the full length of thebarrel 20. This arrangement can minimize the amount of the negative ions being unintentionally attracted to the heated barrel surface, thereby concentrating the negative ions to the hair. - In order to enhance the adhesion of the negative ions to the hair, the
hand grip 10 is provided with apositive electrode 16 for direct contact with a user's hand holding thegrip 10. Thepositive electrode 16 is electrically connected to a voltage source within thegrip 10 to charge the user's body to positive so that the negative ions can be attracted to the positively charged hair. - As shown in FIG. 9, the device may be modified to have one or more
negative ion generators 60 on theend cap 50 either in addition to or in place of those mounted on thehand grip 10. Thenegative ion generators 60 on theend cap 50 are arranged to have their respective ion ports directed mainly axially towards thehand grip 10. Whennegative ion generator 60 are mounted on both of thehand grip 10 and theend cap 50, the individual emission cones overlaps at the regions immediately outwardly of thetongue 34 of theclamp 30 over a major length of thebarrel 20, thereby applying the negative ions concentratedly to the volume of the hair just out of theclamp 30. In this modification, thenegative ion generators 60 on theend cap 50 are set to have their cone emission axes also inclined at an angle () of 10° to 45° with respect to the axis of thebarrel 20 within the horizontal plane in much the same way as the ion generators on thehand grip 10. - FIGS.10 to 12 illustrates another embodiment of the present invention which is basically identical to the above embodiment except that the device is added with a function of straightening the hair. Like parts are designated by like reference numerals with a suffix letter of "A" and no duplicate explanation is deemed necessary. The
hand grip 10A is composed of twogrip haves barrel 20A is composed of twobarrel halves electric heater 40A. Thehair clamp 30A is pivotally supported to thegrip half 11 to have itstongue 34A placed over the rounded surface of thebarrel half 21, precisely the curlingsurface 24A on a part of the rounded surface for curing the hairs clamped therebetween. In association with the pivot movement of the grip halves 11 and 12, the barrel halves 21 and 22 assumes a closed position of bringing the individual flat surfaces in close relation with the each other to clamp the hair therebetween for straightening the hair, and an open position of releasing the hair. In this sense, the flat surfaces are referred to as the straightening surface and designated collectively by reference numerals "25". - The barrel halves 21 and 22 are fitted at their distal end respectively with
end caps end cap 51 is in the form of the water tank containing the volume of water which is supplied for contact with theheater 40A to generate the steam. Thetank 51 includes awick 53 carrying the water and is slidable connected to thebarrel half 21 with a spring interposed between. Upon thetank 51 being depressed, thewick 53 comes into contact with theheater 40A to generate the steam which goes through vents in the periphery of thebarrel half 21 to moisten the hair clamped between thebarrel half 21 and thetongue 34A of theclamp 30A. Thetongue 34A is formed with a plurality of escape holes which are staggered with the vents for escaping the steam. Thepositive electrode 16A is formed on thegrip half 11 for charging the user's hair to positive. - In this embodiment, the
negative ion generators 60A are mounted on thegrip half 11 adjacent to thebarrel half 21 at locations offset axially from thebarrel half 21 and offset radially from thehair clamp 30A. Theion port 82A is oriented to have its cone emission axis (E) inclined at an angle () of 10° to 45° with respect to the axis of thebarrel 20 within the horizontal plane, as shown in FIG. 10, and also inclined at a small angle (ω) of 2° to 30° with respect to the axis of the barrel within the vertical plane, as shown in FIG. 11. It is noted that the vertical plane is normal to a mating plane defined between the closed straightening surfaces 25. Since the mating plane extends in the horizontal plane in alignment with the axis of thebarrel 20A, the cone emission axis (E) is naturally inclined at the small angle (ω) of 2° to 30° with respect to the mating plane or a mating line between the straightening surfaces 25. With this result, the emission cone is intersected by the mating plane at an optimum angle and therefore can certainly cover a region immediately outwardly of the straightening surfaces for imparting the negative ion treatment successfully to the hair out of the straightening surfaces, in addition to cover the region outwardly of thetongue 34A. - As shown in FIG. 13, the device may be modified to have additional
negative ion generators 60A also on thegrip half 12 adjacent to the associatedbarrel half 22. The additionalnegative ion generators 60A are oriented to have the individual cone emission axes inclined oppositely to the negative ion generators on thegrip half 11 so that the emission cones provided by the generators on both of the grip halves 11 and 12 can overlap immediately adjacent to the straightening surfaces 25, thereby concentrating the negative ions to the regions immediately outwardly of the straightening surfaces for optimal negative ion treatment. Further, the negative ion generators may be mounted either alone on the end cap or in addition to those on the hand grip. - The above embodiments and modifications are illustrated only for the purpose of easy understanding of the subject matter of the present invention. Therefore, any combination of the features disclosed herein is also encompassed within the present invention.
- The features disclosed in the foregoing description, in the claims and/or in the accompanying drawings may, both separately and in any combination thereof, be material for realising the invention in diverse forms thereof.
