[0018] Hereinafter, a curling iron according to an embodiment of the present invention will be described with reference to the drawings.
[0019] <1. Overall structure of curling iron> Fig. 1 is a front view of the curling iron 10. Fig. 2 is a side view of the curling iron 10. Fig. 3 is a side view of the curling iron 10 with the clamping portion 62 in an open state.
[0020] The curling iron 10 is configured to easily form curls in the user's hair. The curling iron 10 includes a main body 20, a grip portion 30, and a lower cover 40.
[0021] The main body 20 includes a base 50, a pair of clamping portions 61, 62, a pair of heaters 71, 72, and a pair of plates 81, 82.
[0022] The base 50 is made of, for example, resin. The base 50 has a shape similar to a cylinder. A space is formed inside the base 50 to accommodate a control board that controls the temperatures of the heaters 71, 72, etc. A shaft 50A extends from the bottom surface of the base 50. The shaft 50A is coaxial with the central axis XA of the curling iron. The shaft 50A is inserted into the grip 30.
[0023] An operation unit 51 is disposed on the front surface of the base unit 50. The operation unit 51 includes a monitor 51A, a power button 51B, and temperature adjustment buttons 51C and 51D.
[0024] Monitor 51A displays, for example, the set temperatures of the pair of heaters 71, 72. Power button 51B is operated by user 100 (see FIG. 5) when starting up curling iron 10 or when stopping the operation of curling iron 10. Temperature adjustment buttons 51C, 51D are operated by user 100 when adjusting the set temperatures of the pair of heaters 71, 72. When temperature adjustment button 51C is operated once, for example, the set temperature of the pair of heaters 71, 72 increases by 5°. When temperature adjustment button 51D is operated once, for example, the set temperature of the pair of heaters 71, 72 decreases by 5°.
[0025] The pair of clamping parts 61, 62 are connected to the base 50 and configured to clamp hair 200 (see FIG. 5 ) of the user 100. The clamping part 61 extends along the central axis XA of the curling iron 10. The clamping part 61 is configured integrally with the base 50. Therefore, the position of the clamping part 61 relative to the base 50 does not change. The clamping part 61 may be configured separately from the base 50 and joined to the base 50.
[0026] The clamping portion 62 is configured to be openable and closable relative to the clamping portion 61. The clamping portion 62 extends along the central axis XA in a state facing the clamping portion 61. The clamping portion 62 is biased in a direction facing the clamping portion 61 by a spring (not shown).
[0027] A lever 90 is attached to an end of the clamping portion 62 that is closer to the base portion 50. When the clamping portion 61 and the clamping portion 62 are opposed to each other, the end portion 90A of the lever 90 is operated to approach the base portion 50, whereby the clamping portion 62 is opened relative to the clamping portion 61 (see FIG. 3).
[0028] In the direction in which the central axis XA extends, a pair of recesses 61A, 62A are formed at ends of the pair of clamping parts 61, 62 opposite the base part 50. The pair of recesses 61A, 62A are recessed in a direction perpendicular to the direction in which the central axis XA extends, when the curling iron 10 is viewed from the front. The pair of recesses 61A, 62A are gripped with the fingers of the user 100 when curling the hair 200.
[0029] 4 is a front view of the clamping unit 61. A plurality of ventilation holes 61X for heat dissipation are formed on the inner surface of the clamping unit 61 near the recess 61A. The ventilation holes 61X do not penetrate the clamping unit 61. An ion generating hole 61Y is formed on the inner surface of the clamping unit 61 near the lower end of the plate 81. The ventilation hole 61X also functions as a portion through which ions released from the ion generating hole 61Y pass. This allows ions to be applied to the hair 200.
[0030] 5 is a front view of the clamping part 62. A plurality of ventilation holes 62X for heat dissipation are formed on the inner surface of the clamping part 62 near the recessed part 62A and near the lower end of the plate 82. The ventilation holes 62X do not penetrate the clamping part 62. Since the ventilation holes 61X, 62X are formed near the recessed parts 61A, 62A, the recessed parts 61A, 62A are less likely to heat up while the curling iron 10 is in operation. This allows the depth of the recessed parts 61A, 62A to be made deeper.
[0031] The pair of heaters 71, 72 heat the pair of plates 81, 82. The set temperature range of the pair of heaters 71, 72 can be selected arbitrarily. In this embodiment, in order to suitably form curls on the hair 200, the set temperature range of the pair of heaters 71, 72 is preferably 120° or more and 220° or less. The positions at which the pair of heaters 71, 72 are arranged can be selected arbitrarily as long as they are positions at which the pair of plates 81, 82 can be heated. In this embodiment, the heater 71 is arranged in the vicinity of the plate 81 of the clamping unit 61. The heater 72 is arranged in the vicinity of the plate 82 of the clamping unit 62. The heater 71 heats the plate 81. The heater 72 heats the plate 82.
[0032] 6 is a perspective view of the pair of plates 81, 82. The pair of plates 81, 82 have substantially the same configuration. The pair of plates 81, 82 transfer heat generated by the pair of heaters 71, 72 to the hair 200, thereby heating the hair 200. The pair of plates 81, 82 are made of any metal. In this embodiment, the pair of plates 81, 82 are made of an aluminum alloy.
[0033] The pair of plates 81, 82 are attached to opposing portions of the pair of clamping parts 61, 62. The plate 81 is attached to the clamping part 61. The plate 82 is attached to the clamping part 62. The pair of plates 81, 82 are curved to approach each other. The radii of curvature of the pair of plates 81, 82 in a cross section perpendicular to the central axis XA can be arbitrarily selected as long as curls can be formed in the hair 200. From the viewpoint of forming curls having a certain degree of curvature in the hair 200, it is preferable that the radii of curvature of the pair of plates 81, 82 are in the range of 60 mm or more and 70 mm or less. It is more preferable that the radii of curvature of the pair of plates 81, 82 are 62 mm or less. The radii of curvature of the pair of plates 81, 82 may be the same or different.
[0034] The grip portion 30 shown in FIG. 1 is gripped by a user. The grip portion 30 is made of, for example, resin. The grip portion 30 is cylindrical and is connected to the base portion 50 in an undetachable manner. The shaft 50A of the base portion 50 is inserted into the grip portion 30. Therefore, the main body 20 is rotatable around the central axis XA with respect to the grip portion 30. The rotation angle of the main body 20 around the central axis XA can be selected arbitrarily. In this embodiment, the main body 20 is configured to be rotatable 360° around the central axis XA with respect to the grip portion 30. The main body 20 may be configured to be rotatable around the central axis XA with respect to the grip portion 30 within a range of 0° or more and less than 360°.
[0035] A buffer member 30X is disposed inside the grip portion 30 and between the grip portion 30 and the shaft 50A. The buffer member 30X provides the user with a clicking sensation when the main body 20 rotates. The buffer member 30X also has a function of preventing the grip portion 30 from accidentally rotating around the shaft 50A when the user operates the lever 90 while gripping the grip portion 30.
[0036] The lower cover 40 is made of, for example, resin. The lower cover 40 has a main body 41 and a stand 42. The main body 41 closes the bottom surface of the gripping part 30. The central axis of the main body 41 is coaxial with the axis 50A. The main body 41 rotates with respect to the gripping part 30, but does not rotate with respect to the axis 50A. The power cord 300 is connected to the main body 41. The stand 42 is integrally formed with the main body 41. The stand 42 may be formed separately from the main body 41 and joined to the main body 41. The stand 42 protrudes from a position of the main body 41 opposite the lever 90 with respect to the central axis XA in a side view of the curling iron 10. Therefore, when the curling iron 10 is placed so that the stand 42 contacts a desk or the like, the lever 90 is located upward regardless of the rotation position of the gripping part 30. Therefore, the curling iron 10 is likely to be in a stable position when placed on a desk or the like.
[0037] <2. How to use the curling iron> When the power cord 300 is connected to a power source, the user 100 operates the power button 51B to supply power to the control board. As a result, the pair of heaters 71, 72 start heating. The user 100 adjusts the set temperatures of the pair of heaters 71, 72 to the desired temperature by operating the temperature adjustment buttons 51C, 51D.
[0038] Next, the user 100 grasps the gripping portion 30 with one hand 100A, and operates the lever 90 with the fingers of the hand 100A so that the end 90A of the lever 90 approaches the base 50. This creates a state in which the clamping portion 62 is open relative to the clamping portion 61 (see FIG. 3). Next, the user inserts the hair 200 between the pair of clamping portions 61, 62, and releases the fingers from the lever 90. The clamping portion 62 faces the clamping portion 61 due to the biasing force of the spring. This creates a state in which the hair 200 is clamped by the pair of clamping portions 61, 62, more specifically, by the pair of plates 81, 82, as shown in FIG. 7.
[0039] The user 100 grips the recesses 61A, 62A of the pair of clamping parts 61, 62 with the fingers of the other hand 100B. The user moves the curling iron 10 along the flow of the hair while keeping the hair 200 clamped between the pair of plates 81, 82. As a result, curls are formed in the hair along the curved surfaces of the pair of plates 81, 82.
[0040] Furthermore, the user may rotate the main body 20 about the central axis XA relative to the grip portion 30, and then move the curling iron 10 along the flow of the hair. By rotating the main body 20 about the central axis XA relative to the grip portion 30, curls having a larger curvature can be formed in the hair 200.
[0041] <3. Effects of hair iron> The curling iron 10 provides the following effects.
[0042] <3-1> The curling iron 10 is curved so that the pair of plates 81, 82 that heat the hair 200 approach each other. Therefore, curls can be easily formed in the hair 200 by moving the curling iron 10 along the flow of the hair while the hair 200 is held between the pair of clamping parts 61, 62.
[0043] <3-2> Since recesses 61A, 62A are formed at the tips of the pair of clamping parts 61, 62, the recesses 61A, 62A can be grasped with fingers when the hair 200 is clamped by the pair of clamping parts 61, 62. Therefore, the operation of moving the curling iron 10 with the hair 200 clamped can be easily performed.
[0044] <3-3> The pair of clamping parts 61, 62 are configured to be rotatable relative to the gripping part 30, so that curls of a larger curvature can be formed on the hair 200.
[0045] <3-4> Since the pair of clamping parts 61, 62 can rotate 360° relative to the gripping part 30, the operability of the pair of clamping parts 61, 62 when curling the hair 200 is improved.
[0046] <3-5> Since the radius of curvature of the pair of plates 81, 82 is within the range of 60 mm to 70 mm, curls with a larger curvature can be formed on the hair 200.
[0047] <3-6> With the hair 200 clamped between the pair of clamping parts 61, 62, the curvature of the curls formed in the hair 200 can be adjusted by adjusting the rotation angle of the pair of clamping parts 61, 62 relative to the gripping part 30. This makes it possible to easily form curls of a desired curvature in the hair 200.
[0048] The above embodiments are examples of possible forms of the curling iron of the present invention, and are not intended to limit the forms. The curling iron of the present invention may take forms different from those exemplified in each embodiment. One example is a form in which part of the configuration of each embodiment is replaced, changed, or omitted, or a form in which a new configuration is added to each embodiment. Below are some examples of modified versions of each embodiment. The following modified versions can be combined with each other as long as they are not technically inconsistent.
[0049] <4-1> In the above embodiment, the main body 20 may be configured to be non-rotatable with respect to the grip portion 30 .
[0050] <4-2> In the above embodiment, power is supplied to the control board, etc. of the curling iron 10 by connecting the power cord 300 to a power source, but power may also be supplied to the control board, etc. by, for example, a primary or secondary battery housed in the gripping portion 30 or the base portion 50.
