Description

FIELD OF THE DISCLOSURE

The present disclosure relates generally to a hair styling apparatus and, more particularly, to a hair styling apparatus including positionable heating plate covers that facilitate the hair styling apparatus operating in a straightener mode and/or a curling wand mode.

BACKGROUND

Traditional hair styling apparatuses have a pair of arms that are hingedly connected to permit manual opening and closing of the arms relative to one another for clamping hair between the arms and straightening or curling the hair. Each arm typically includes a hair heating surface that is heated during a styling operation. During use, hair is positioned between the hair heating surfaces and the hair is styled. Since traditional hair stylers perform either straightening or curling, a user must use two separate hair styling apparatuses to satisfy both their straightening and curling needs.
Based on the foregoing, a need exists for a safe and economical hair styling apparatus that can both straighten and curl hair.

BRIEF DESCRIPTION

The present disclosure describes a hair styling apparatus and, more particularly, a combination hair styling apparatus capable of selectively switching between a straightener mode and a curling wand mode.
In one embodiment, a hair styling apparatus includes first and second arms each having first and second ends. The first and second arms may be pivotably coupled to each other at least at the first ends of the arms for selective, pivotal movement relative to each other to selectively configure the hair styling apparatus between an opened position and a closed position. The hair styling apparatus also includes a first pair of heating plates, and each of the first heating plates define a hair contact surface. Each of the first heating plates is connected to an inner portion of the first and second arms. The hair styling apparatus also includes a second pair of heating plates, and each of the second heating plates define a hair contact surface. Each of the second heating plates may be connected to an outer portion of the first and second arms.
The hair styling apparatus may also include a pair of heating plate covers, and each of the heating plate covers may be connected to each of the second heating plates. Each of the heating plate covers is slidably movable between a first position and a second position. The first position covers a corresponding second heating plate and the second position exposes the corresponding second heating plate for use.
Each of the first and second arms may include a heating element connected to the first and second heating plates and configured to heat the first and second heating plates. In some instances, each of the first and second arms may include a first heating element connected to the first heating plates and a second heating element connected to the second heating plates.
The hair styling apparatus may further include at least one switch. The at least one switch may activate/deactivate either the first pair of heating plates or the second pair of heating plates when at least one of the heating plate covers is in the first position, the second position, or moves between the first position and the second position.
In some embodiments, each of the first and second arms of the hair styling apparatus may define a slot. The slot may be configured to receive at least a portion of the corresponding heating plate cover such that the heating plate cover is slidable between the first position and the second position. In some instances, a switch may be positioned in the slot of the first arm such that the heating plate cover connected to the first arm engages with the switch when sliding between the first position and the second position.
In some instances, each of the first and second arms may define a first slot and a second slot. The first and second slots may be oppositely positioned from each other. The first and second slots may be configured to each receive at least a portion of the corresponding heating plate cover such that the heating plate cover is slidable between the first position and the second position.

As shown in Figs. 3-6, upper arm 12 includes an upper grip 20 and an upper clamp head 22. Upper clamp head 22 defines inner upper heating area 24 and outer upper heating area 26. Inner upper heating area 24 is opposite from outer upper heating area 26. Upper clamp head 22 includes inner upper heating plate 28 positioned within inner upper heating area 24. Inner upper heating plate 28 further defines inner upper hair heating surface 30. Inner upper hair heating surface 30 may be planar, curved, twisted, and combinations thereof. Upper clamp head 22 includes upper heating plate cover 32 positioned within outer upper heating area 26. Upper clamp head 22 includes outer upper heating plate 29 positioned within outer upper heating area 26. Outer upper heating plate 29 further defines outer upper hair heating surface 31. In the example, outer upper hair heating surface 31 is curved. However, outer upper hair heating surface 31 may be planar, curved, twisted, and combinations thereof.
Heating plate cover 32 is connected to outer upper heating plate 29. Heating plate cover 32 is movably connected to outer upper heating plate 29. Heating plate cover 32 may define an inner surface that is similar to the outer surface of at least hair heating surface. For example, heating plate cover 32 may define an inner curved surface. In some instances, heating plate cover 32 may define a lateral cross-section that is curved. However, it should be understood that heating plate cover 32 may define an inner surface that is a variety of shapes, without departing from the spirit/scope of this disclosure.
Lower arm 14 includes a lower grip 34 and a lower clamp head 36. Lower clamp head 36 defines an inner lower heating area 38 and an outer lower heating area 40. Inner lower heating area 38 is opposite from outer lower heating area 40. Lower clamp head 36 includes an inner lower heating plate 42 positioned within inner lower heating area 38. Inner lower heating plate 42 further defines an inner lower hair heating surface 44. Inner lower hair heating surface 44 may be planar, curved, twisted, and combinations thereof. In the example, inner lower hair heating surface 44 is planar. Lower clamp head 36 includes a lower heating plate cover 46 positioned within outer lower heating area 40. Lower clamp head 36 includes an outer lower heating plate 43 positioned within outer lower heating area 40. Outer lower heating plate 43 further defines an outer lower hair heating surface 45. In the example, outer upper hair heating surface 31 is curved. However, outer lower hair heating surface 45 may be planar, curved, twisted, and combinations thereof.
Heating plate cover 46 is connected to outer lower heating plate 43. Heating plate cover 46 is movably connected to outer lower heating plate 43. Heating plate cover 46 defines an inner surface that is similar to the outer surface of at least hair heating surface. For example, heating plate cover 46 defines an inner curved surface. In some instances, heating plate cover 46 defines a lateral cross-section that is curved. However, it should be understood that heating plate cover 46 may define an inner surface that is a variety of shapes, without departing from the spirit/scope of this disclosure.
Upper clamp head 22 includes a tip 66. Lower clamp head 36 includes a tip 68. Tips 66, 68 are positioned at second ends of arms 12, 14 opposite from the first ends where power cord 18 extends outwardly from hair styling apparatus 10. Tips 66, 68 may be positioned on either side of longitudinal axis 60 such that longitudinal axis 60 extends between tips 66, 68. Tips 66, 68 are manufactured from a material that does not substantially increase in temperature when one or more heating plate 28, 29, 42, 43 is active. Tips 66, 68 are at least partially manufactured from a material with a low thermal conductivity (e.g., rubber, plastic). Tip 66, 68 are flared outwardly. For example, tips 66, 68 are flared in a direction away from longitudinal axis 60. A user may grip tips 66, 68 so as to maneuver and/or spin hair styling apparatus 10 without touching heating plates 28, 29, 42, 43.
As shown in at least in Figs. 1-7B, hair styling apparatus 10 includes upper arm 12 and lower arm 14, each arm defining at least two heating areas (e.g., inner heating area 24, 38 and outer heating area 26, 40). Inner heating area 24, 38 and outer heating area 26, 40 may be utilized to perform various hair styling tasks (e.g., straightening, curling, and combinations thereof). For example, inner heating plates 28, 42, alone or in combination, may be utilized to perform various hair styling tasks (e.g., straightening, curling, and combinations thereof). In another example, outer heating plates 29, 43, alone or in combination, may be utilized to perform various hair styling tasks (e.g., straightening, curling, and combinations thereof). In some instances, when inner heating plates 28, 42 are activated, outer heating plates 29, 43 may be deactivated. In other instances, when inner heating plates 28, 42 are deactivated, outer heating plates 29, 43 may be activated. In other instances, when inner heating plates 28, 42 are activated, outer heating plates 29, 43 may be activated.
Referring to outer heating area 26, 40, heating plate cover 32, 46 at least partially covers outer heating plate 29, 43. For example, upper heating plate cover 32 completely covers outer upper hair heating surface 31 of outer upper heating plate 29. In some examples, upper heating plate cover 32 may cover outer upper hair heating surface 31 and at least partially cover tip 66. In another example, upper heating plate cover 32 may substantially cover outer upper hair heating surface 31 and tip 66. Lower heating plate cover 46 at least partially covers outer lower hair heating surface 45 of outer lower heating plate 43. In some examples, lower heating plate cover 46 may cover outer lower hair heating surface 45 and at least partially cover tip 68. In another example, lower heating plate cover 46 may substantially cover outer lower hair heating surface 45 and tip 68. In one example, heating plate cover 32, 46 covers heating plate 29, 43 such that hair heating surface 31, 45 of outer heating plate 29, 43 is "shielded". As used herein, "shielded" refers to inhibiting contact, either directly or indirectly, with a surface. For example, shielding of hair heating surface 31, 45 of outer heating plate 29, 43 may ensure a user does not inadvertently burn themselves, in the event the outer heating plate 29, 43 are hot but not intended for use. Heating plate cover 32, 46 may be configured to limit heat conduction. For example, heating plate cover 32, 46 may be at least partially manufactured from a material with a low thermal conductivity (e.g., rubber, plastic). Heating plate covers 32, 46 may be manufactured from a material that does not substantially increase in temperature when one or more heating plate 28, 29, 42, 43 is active,
Heating plate covers 32, 46 are movably positioned relative to outer heating plates 29, 43. For example, heating plate covers 32, 46 are slidably engaged with arms 12, 14 such that each heating plate cover 32, 46 moves between a first position and a second position. Heating plate cover 32, 46 may slide between the first position and the second position to at least partially expose hair heating surface 31, 45 of outer heating plate 29, 43 or at least partially conceal outer hair heating surface 31, 45 of heating plate 29, 43. Heating plate covers 32, 46 may slide between the first position and the second position to expose hair heating surface 31, 45 of outer heating plate 29, 43 or conceal hair heating surface 31, 45 of outer heating plate 29, 43. In some embodiments, heating plate covers 32, 46 in the second position may lock arms 12, 14 in the closed position such that arms 12, 14 cannot be opened when heating plate 29, 43 are exposed. Heating plate covers 32, 46 may slide between the first position and the second position along longitudinal axis 60. In some instances, heating plate covers 32, 46 may include a protrusion to engage directly or indirectly with arms 12, 14 to facilitate movement between the first position and the second position.
Upper heating plate cover 32 includes upper heating plate cover protrusion 52 and is movably (e.g., slidably) engaged with an upper slot 48 of arm 12. Upper slot 48 extends between upper tip 66 and the first end of arm 12. In the example, power cord 18 extends outwardly from the first end of arm 12. Upper slot 48 extends along longitudinal axis 60. For example, upper slot 48 may extend parallel to longitudinal axis 60 between upper tip 66 and first end of arm 12. Lower heating plate cover 46 includes lower heating plate cover protrusion 54 and is movably (e.g., slidably) engaged with a lower slot 50 of arm 14. Lower slot 50 may extend between lower tip 68 and first end of arm 14. Lower slot 50 may extend along longitudinal axis 60. For example, lower slot 50 may extend parallel to longitudinal axis 60 between lower tip 68 and the first end of arm 14.
In some embodiments, for example as depicted in Figs. 7A-7B, arm 12 may define at least two upper slots 48 and arm 14 may define at least two lower slots 50. The two upper slots 48 may extend between upper tip 66 and the first end of arm 12 along longitudinal axis 60. The two lower slots 50 may extend between lower tip 68 and the first end of arm 14 along longitudinal axis 60. The two upper slots 48 may be defined oppositely from each other along arm 12. For example, if one of the two upper slots 48 is positioned at 0 degrees, the second of the two upper slots 48 may be positioned at 180 degrees relative to the other upper slot 48. However, it should be understood that the two upper slots 48 may be positioned in a variety of locations around arm 12 and along longitudinal axis 60 so as to guide heating plate cover protrusion 52 of heating plate cover 32 between the first position and the second position. The two lower slots 50 may be defined oppositely from each along arm 14. For example, if one of the two lower slots 50 is positioned at 0 degrees, the second of the two lower slots 50 may be positioned at 180 degrees relative to the other lower slot 50. However, it should be understood that the two lower slots 50 may be positioned in a variety of locations around arm 14 and along longitudinal axis 60 so as to guide heating plate cover protrusion 54 of heating plate cover 46 between the first position and the second position.
In one example, upper heating plate cover 32 may be positioned near upper tip 66 and may slide in a direction parallel to the longitudinal axis and toward/away from the first end of arm 12(e.g., the end of hair styling apparatus 10 where power cord 18 extends from). In some examples, upper heating plate cover 32 may be positioned to substantially cover upper tip 66 and may slide in a direction parallel to the longitudinal axis and toward/away from the first end of arm 12(e.g., the end of hair styling apparatus 10 where power cord 18 extends from). Similarly, lower heating plate cover 46 may be positioned near lower tip 68 and may slide in a direction parallel to the longitudinal axis and toward/away from the first end of arm 14(e.g., the end of hair styling apparatus 10 where power cord 18 extends from).
