- a power supply cord 9 is connected to one of end portions (right end portions in Fig. 1 ) of the grip portions 3.
- a bundle of the hair H is clipped between the upper hair clip surface 4A and the lower hair clip surface 4B, whereby the hair H thus clipped is warmed between the upper hair clip surface 4A and the lower hair clip surface 4B.
- the hair iron 10 is pulled down toward tips of the hair H while being slid along the hair H, whereby straight styling can be given to the hair H.
- a plurality of protruding/recessed portions 5 (refer to Fig. 1 ) , which have the same shape thereamong and are extended along the width direction of the clip portions 2, are provided.
- recessed portions 5a of the protruding/recessed portions 5 are recessed into a semicircular shape, and tip ends of protruding portions 5b of the protruding/recessed portions 5 are formed into a flat shape.
- the space portions 6 are formed between the upper hair clip surface 4A and the lower hair clip surface 4B, whereby pressing force to clip the hair H is lowered, thus making it possible to slide the hair H by appropriate friction force. In such a way, damage to be done to the hair H can be suppressed.
- a dimension of the space portions 6 to be formed when the protruding portions 5b of one of the upper and lower hair clip surfaces 4A and 4B enter the recessed portions 5a of the other thereof can range approximately from 0.05 millimeters to 0.5 millimeters.
- Reasons for this are as follows. Since a general diameter of the hair H is 0.05 millimeters or more, the pressing force to clip the hair H is strengthened when the dimension of the space portions 6 is set at less than 0.05 millimeters. On the contrary, when the dimension of the space portions 6 is set too large, effective pressing force cannot be applied to the hair H, and the straight styling cannot be given to the hair H.
- the lower hair clip surface (second hair clip surface) 4B as one of the upper and lower hair clip surfaces 4A and 4B is supported so as to be freely movable relative to the case (clip portion main body) 22.
- float springs 12 are arranged at positions corresponding to four corners of the hair clip member 16, and the plate portion 16a of the hair clip member 16 is supported so as to be movable reciprocally up and down while interposing the float springs 12 between the plate portion 16a concerned and the lower hair clip surface 4B.
- the lower hair clip surface 4B is supported so as to be movable up and down with respect to the case 22 by using urging force of the float springs 12.
- the lower hair clip surface 4B when the hair H is clipped between the upper hair clip surface 4A and the lower hair clip surface 4B, the lower hair clip surface 4B relatively moves in response to an amount of the clipped hair H while enhancing adherence of the hair H onto the upper hair clip surface 4A side on which the protruding/recessed portions 5 are formed. In such a way, the straight styling can be effectively given to the hair H while suppressing the damage to be done to the hair H to the minimum.
- the four corners of the hair clip member 16 are supported by the float springs 12, and it is possible to appropriately set the positions of the float springs 12 and the number thereof to be arranged. Moreover, it is preferable that an up-and-down movable range of the hair clip member 16 be set so as to range approximately from 0 to 3 millimeters. Reasons for this are as follows. When a movement amount of the hair clip member 16 becomes 3 millimeters or more, a load to be applied to the clipped hair H and the friction force to be generated at the time of pulling down the hair H are increased, and it becomes difficult to slide the hair iron 10 smoothly along the hair H.
- a plurality of guide protrusions 24 are provided, which are formed along the longitudinal direction of the clip portions 2, and guide the hair H along the width direction of the clip portions 2.
- the hair iron 10 of this embodiment includes: the upper clip portion (first clip portion) 2A having the upper hair clip surface (first hair clip surface) 4A; and the lower clip portion (second clip portion) 2B having the lower hair clip surface (second hair clip surface) 4B.
- the space portions 6 are formed therebetween. Therefore, the pressing force to clip the hair H is lowered, thus making it possible to slide the hair H by the appropriate friction force along the width direction of the clip portions 2. In such a way, the damage to be done to the hair H can be suppressed.
- the space portions 6 are provided between the upper and lower hair clip surfaces 4A and 4B as described above, whereby a degree of freedom of the hair H to be clipped therebetween can be ensured appropriately. Accordingly, an effect of arranging a flow of the hair H can be further enhanced.
- the plurality of protruding/recessed portions 5 are provided on the upper and lower hair clip surfaces 4A and 4B, and the semicircular recessed portions 5a of the upper hair clip surface 4A and the protruding portions 5b of the lower hair clip surfaces 4B, in which the tip ends are formed into the flat shape, are brought into contact with each other, whereby the space portions 6 are formed. Therefore, in comparison with a configuration in which the protruding/recessed portions are provided only on either one of the hair clip surfaces, surface areas of the upper and lower hair clip surfaces 4A and 4B can be increased. As described above, the surface areas of the upper and lower hair clip surfaces 4A and 4B are increased, thus making it possible to increase a supply range of thermal energy to be given to the hair. In such a way, the straight styling can be effectively given to the hair.
- the plurality of protruding/recessed portions 5 are provided on the upper and lower hair clip surfaces 4A and 4B, whereby the space portions 6 are formed; however, the plurality of protruding/recessed portions 5 may be provided only on the upper hair clip surface 4A as one of the upper and lower hair clip surfaces 4A and 4B. Then, it becomes possible to form the space portions 6 by a simple configuration in which the lower hair clip surface 4B is a flat surface.
- the recessed portions 5a and protruding portions 5b of the plurality of protruding/recessed portions 5 are individually extended along the width direction of the clip portions 2, and accordingly, even if the hair H that inclines or becomes perpendicular with respect to the width direction concerned is clipped between the upper and lower hair clip surfaces 4A and 4B, the flow of the hair H can be arranged.
- the space portions 6 formed of the plurality of protruding/recessed portions 5 are open to the both widthwise sides of the clip portions 2 in the upper and lower hair clip surfaces 4A and 4B, and accordingly, the straight styling can be given to the hair H with ease by sliding the clip portions 2 along the width direction.
- the lower hair clip surface (second hair clip surface) 4B as one of the upper and lower hair clip surfaces 4A and 4B is supported so as to be freely movable relative to the case (clip portion main body) 22. Therefore, the lower hair clip surface 4B relatively moves in response to the amount of the clipped hair H while enhancing the adherence of the hair H onto the upper hair clip surface (first hair clip surface) 4A side on which the protruding/recessed portions 5 are formed, whereby the straight styling can be effectively given to the hair H while suppressing the damage to be done to the hair H to the minimum.
- the plurality of guide protrusions 24 are provided, which are formed along the longitudinal direction of the clip portions 2, and guide the hair H along the width direction of the clip portions 2. Therefore, at the time of sliding the clipped hair H along the width direction of the clip portions 2, the hair H can be suppressed from spreading in the longitudinal direction of the clip portions 2.
- the guide protrusions 24 for arranging the flow of the hair H are provided on the upper clip portion (first clip portion) 2A on a fixed side (side where the hair clip surface does not move) in which, in comparison with the case where the hair clip surface moves, the adherence is higher, and the effect of arranging the flow of the hair H can be strongly exerted. In such a way, the effect of arranging the flow of the hair H can be further enhanced.
- the projections (heat radiation portions) 25 and 26 are provided on widthwise side surfaces of the upper and lower clip portions 2A and 2B, and accordingly, at the time of using the hair iron 10, contact areas between the clip portions 2 and the scalp and skin of the user can be reduced.
- the heat radiation portions are the plurality of projections 25 and 26 provided, so as to be extended in the longitudinal direction of the clip portions 2, on at least one-side side surfaces in the width direction of the upper and lower clip portions 2A and 2B. Accordingly, surface areas of the clip portions 2 are increased, thus making it possible to efficiently radiate the heat.
- the present invention is not limited to the above-described embodiment, and is modifiable in various ways within the scope without departing from the spirit of the present invention.
- the recessed portions 5a of the upper hair clip surface 4A and the protruding portions 5b of the lower hair clip surface 4B are brought into contact with each other, whereby the space portions 6 are formed; however, as in a modification example shown in Fig. 4 , the protruding portions 5b of the upper hair clip surface 4A and the protruding portions 5b of the lower hair clip surface 4B are brought into contact with each other, whereby the space portions 30 may be formed.
- the recessed portions 5a of the upper and lower hair clip surfaces 4A and 4B become the space portions 30.
- a photocatalytic function may be imparted to each of the hair clip surfaces 4.
- a coating material 4a containing photocatalyst particles is applied and coated on the surface of the plate portion 15a (16a)
- photocatalyst particles 4b are contained in the plate portion 15a (15a), whereby the photocatalytic function can be imparted to each of the hair clip surfaces 4.
- a sterilization function, a deodorization function and the like can be imparted to the hair clip surfaces 4.
- a publicly known material such as silver can be used; however, it is particularly preferred to use titanium dioxide.
- the titanium dioxide is used as described above, whereby a hydrophilic function can be imparted to the hair clip surfaces 4 by the titanium dioxide concerned, and a moist feeling and a smooth and silky feeling can be given to the hair thereby.

- This application is based upon and claims the benefit of priority from prior Japanese Patent Application
P2009-253291 filed on November 4,2009 - The present invention relates to a hair iron.
- Heretofore, as disclosed in Japanese Patent Laid-Open Publication No.
H11-32831 - However, the above-described conventional hair iron has a configuration in which the wavy portions of the pair of hair clip surfaces are fitted to each other and meshed with each other. In such a configuration, at the time of sliding the clipped hair along the width direction of the clip portions, pressing force to clip the hair is large. Accordingly, it has been apprehended that the hair may be damaged as a result of application of friction force more than necessary to surfaces of the hair.
- In this connection, it is an object of the present invention to provide a hair iron capable of finishing the hair straight while making it possible to suppress such damage done to the hair.
- In order to achieve the foregoing object, a hair iron is provided, which include a first clip portion having a first hair clip surface, and a second clip portion having a second hair clip surface, and clips hair between the first hair clip surface and the second hair clip surface, wherein, when a pair of the first and second hair clip surfaces are brought into contact with each other in a state of not clipping the hair therebetween, space portions are formed therebetween.
- In accordance with the present invention, when the first hair clip surfaces and the second hair clip surfaces are brought into contact with each other in the state of not clipping the hair therebetween, the space portions are formed therebetween. Therefore, pressing force to clip the hair is lowered, thus making it possible to slide the hair by appropriate friction force along a width direction of the clip portions. In such a way, damage to be done to the hair can be suppressed.

Moreover, the description is made on the premise that a clip portion side of the hair iron is located forward, and that a grip portion side thereof is located rearward.
-
Fig. 1 to Fig. 3 are views showing an embodiment of a hair iron according to the present invention. As shown inFig. 1 andFig. 2 , ahair iron 10 of this embodiment is composed of a pair ofarms 1, in each of which aclip portion 2 is arranged on a tip end side of thehair iron 10 concerned, and agrip portion 3 is arranged on a base end side thereof. Here, each of theclip portions 2 has ahair clip surface 4 that clips hair, and thegrip portion 3 is gripped by a user. - Specifically, the pair of
arms 1 include: anupper arm 1A in which an upper clip portion (first clip portion) 2A and anupper grip portion 3A are integrated with each other; and alower arm 1B in which a lower clip portion (second clip portion) 2B and alower grip portion 3B are integrated with each other. - Then, in this embodiment, a base end portion of the
upper arm 1A and a base portion of thelower arm 1B are freely rotatably coupled to each other while interposing arotational coupling portion 11 therebetween. Specifically, the pair ofarms 1 are made freely rotatable between an expansion position where theupper clip portion 2A and thelower clip portion 2B are separated from each other to form a substantially V-shape and a clip position where theupper clip portion 2A and thelower clip portion 2B contact each other to form a straight line shape. - Moreover, the
upper clip portion 2A and thelower clip portion 2B include an upper hair clip surface (first hair clip surface) 4A and a lower hair clip surface (second hair clip surface) 4B, respectively, which are capable of abutting against each other at the time when theupper arm 1A and thelower arm 1B are rotated to close. - Note that, in this embodiment, a width direction of the
clip portions 2 corresponds to an extended direction of hair H in a state where the hair H is clipped between the upperhair clip surface 4A and the lowerhair clip surface 4B. Moreover, a longitudinal direction of theclip portions 2 corresponds to a direction intersecting the extended direction of the hair H. - The above-mentioned upper and
lower arms cases case 21 andcase 22. - Moreover, on widthwise side surface portions of the
case 21 and thecase 22,projections 25 andprojections 26, which serve as heat radiation portions extended in a longitudinal direction of thecases projections 25 and twoprojections 26 are provided on both widthwise side portions of thecase 21 and thecase 22, respectively, and are extended so as to have substantially the same length as a longitudinal length of the upper and lowerhair clip surfaces - As described above, the
projections 25 and theprojections 26, which are extended in the longitudinal direction, are provided on thecase 21 and thecase 22, whereby, at the time of using thehair iron 10, contact areas between thecases projections case 21 and thecase 22 are increased, and accordingly, heat can be radiated therefrom efficiently. - Moreover, in this embodiment, surfaces of the case (clip portion main body) 21 and the case (clip portion main body) 22, which are opposite to each other, are allowed to support thereon a
hair clip member 15 having the upperhair clip surface 4A and ahair clip member 16 having the lowerhair clip surface 4B, whereby the upper clip portion (first clip portion) 2A and the lower clip portion (second clip portion) 2B are formed. - Specifically, the
hair clip member 15 and thehair clip member 16 include aplate portion 15a and aplate portion 16a, each of which has a substantially thin plate shape. On surfaces of theplate portion 15a and theplate portion 16a, the upperhair clip surface 4A and the lowerhair clip surface 4B are formed. Note that, preferably, theplate portion 15a and theplate portions 16a are formed, for example, of a material such as copper and aluminum, which has high electric conductivity, thus making it easy to transmit heat to the hair H. - Then, heaters 13 (13A, 13B) are arranged on back surfaces of the
plate portion 15a and theplate portion 16a in an abutting manner, respectively. In this embodiment, positive temperature coefficient heaters (PTC heaters) are used as theheaters 13, whereby it becomes possible to continuously control temperature of theheaters 13. Note that, though the PTC heaters are illustrated as theheaters 13 in this embodiment, Nichrome wire heaters and other heating means may be used without being limited to the PTC heaters. Moreover, a configuration may be adopted, in which one of the heaters (heat generating portions) 13 is provided only on either one of the upper clip portion (first clip portion) 2A and the lower clip portion (second clip portion) 2B. - Moreover, in the inside of the
case 21, acontrol circuit 14 that controls the temperature of theheaters 13, and the like is housed, and theheaters 13 are electrically connected to thiscontrol circuit 14. Furthermore, in this embodiment, temperature of the upperhair clip surface 4A and the lowerhair clip surface 4B is adapted to be settable step by step. - On the
upper grip portion 3A side of thecase 21, an operation switch 7 is provided. ON/OFF of energization to theheaters 13 can be switched by operating this operation switch 7. When theheaters 13 are energized by operating the operation switch 7, theheaters 13 concerned generate heat, and the heat is transmitted to theplate portion 15a and theplate portion 16a from therespective heaters 13 which have generated the heat, whereby the upperhair clip surface 4A of theplate portion 15a and the lowerhair clip surface 4B of theplate portion 16a are heated. - Moreover, on the
upper grip portion 3A side of thecase 21, twotemperature adjustment switches 8 are provided, and the set temperature of the upperhair clip surface 4A and the lowerhair clip surface 4B are adapted to be switchable by operating the twotemperature adjustment switches 8. In this embodiment, the temperature adjustment switches 8, which are made capable of switching the set temperature to five stages, are illustrated. Moreover, on thecase 21, fivelighting portions 8a are provided by using LED lamps. For example, one of thelighting portions 8a, which corresponds to each of the stages, is lighted, whereby it is made possible to recognize the present set temperature. Note that, though not shown inFig. 1 , apower supply cord 9 is connected to one of end portions (right end portions inFig. 1 ) of thegrip portions 3. - Hence, a bundle of the hair H is clipped between the upper
hair clip surface 4A and the lowerhair clip surface 4B, whereby the hair H thus clipped is warmed between the upperhair clip surface 4A and the lowerhair clip surface 4B. Then, thehair iron 10 is pulled down toward tips of the hair H while being slid along the hair H, whereby straight styling can be given to the hair H. - Here, in this embodiment, when the upper and lower
hair clip surfaces hair clip surfaces space portions 6 are formed therebetween. - Specifically, in this embodiment, on the upper
hair clip surface 4A and the lowerhair clip surface 4B, a plurality of protruding/recessed portions 5 (refer toFig. 1 ) , which have the same shape thereamong and are extended along the width direction of theclip portions 2, are provided. Moreover, in this embodiment, recessedportions 5a of the protruding/recessed portions 5 are recessed into a semicircular shape, and tip ends of protrudingportions 5b of the protruding/recessed portions 5 are formed into a flat shape. - In such a configuration, as shown in
Fig. 3 , when therecessed portions 5a of the upperhair clip surface 4A and the protrudingportions 5b of the lowerhair clip surface 4B are brought into contact with each other, and the protrudingportions 5b of the upperhair clip surface 4A and the recessedportions 5a of the lowerhair clip surface 4B are brought into contact with each other, thespace portions 6 are formed between the upper and lowerhair clip surfaces space portions 6 are open to both widthwise sides of theclip portions 2 in the upper and lowerhair clip surfaces - As described above, the
space portions 6 are formed between the upperhair clip surface 4A and the lowerhair clip surface 4B, whereby pressing force to clip the hair H is lowered, thus making it possible to slide the hair H by appropriate friction force. In such a way, damage to be done to the hair H can be suppressed. - Note that, in this embodiment, it is preferable to make design so that a dimension of the
space portions 6 to be formed when the protrudingportions 5b of one of the upper and lower hair clip surfaces 4A and 4B enter the recessedportions 5a of the other thereof can range approximately from 0.05 millimeters to 0.5 millimeters. Reasons for this are as follows. Since a general diameter of the hair H is 0.05 millimeters or more, the pressing force to clip the hair H is strengthened when the dimension of thespace portions 6 is set at less than 0.05 millimeters. On the contrary, when the dimension of thespace portions 6 is set too large, effective pressing force cannot be applied to the hair H, and the straight styling cannot be given to the hair H. - Moreover, at least the lower hair clip surface (second hair clip surface) 4B as one of the upper and lower hair clip surfaces 4A and 4B is supported so as to be freely movable relative to the case (clip portion main body) 22.
- Specifically, as shown in
Fig. 2 , in the inside of thecase 22, four float springs 12 are arranged at positions corresponding to four corners of thehair clip member 16, and theplate portion 16a of thehair clip member 16 is supported so as to be movable reciprocally up and down while interposing the float springs 12 between theplate portion 16a concerned and the lowerhair clip surface 4B. In other words, in this embodiment, the lowerhair clip surface 4B is supported so as to be movable up and down with respect to thecase 22 by using urging force of the float springs 12. - In such a configuration, when the hair H is clipped between the upper
hair clip surface 4A and the lowerhair clip surface 4B, the lowerhair clip surface 4B relatively moves in response to an amount of the clipped hair H while enhancing adherence of the hair H onto the upperhair clip surface 4A side on which the protruding/recessed portions 5 are formed. In such a way, the straight styling can be effectively given to the hair H while suppressing the damage to be done to the hair H to the minimum. - Note that, in this embodiment, the four corners of the
hair clip member 16 are supported by the float springs 12, and it is possible to appropriately set the positions of the float springs 12 and the number thereof to be arranged. Moreover, it is preferable that an up-and-down movable range of thehair clip member 16 be set so as to range approximately from 0 to 3 millimeters. Reasons for this are as follows. When a movement amount of thehair clip member 16 becomes 3 millimeters or more, a load to be applied to the clipped hair H and the friction force to be generated at the time of pulling down the hair H are increased, and it becomes difficult to slide thehair iron 10 smoothly along the hair H. - Moreover, as shown in
Fig. 1 , on both widthwise ends of the upper clip portion (first clip portion) 2A, a plurality ofguide protrusions 24 are provided, which are formed along the longitudinal direction of theclip portions 2, and guide the hair H along the width direction of theclip portions 2. - In this embodiment, on each of widthwise outsides of the upper
hair clip surface 4A, which correspond to the vicinities of long sides thereof, eight pieces of theguide protrusions 24 are arranged at an equal interval. In such a way, at the time of clipping the hair H between the upper and lower hair clip surfaces 4A and 4B, followed by sliding, the hair H can be suppressed from spreading in the longitudinal direction of theclip portions 2. - As described above in detail, the
hair iron 10 of this embodiment includes: the upper clip portion (first clip portion) 2A having the upper hair clip surface (first hair clip surface) 4A; and the lower clip portion (second clip portion) 2B having the lower hair clip surface (second hair clip surface) 4B. Moreover, in thehair iron 10, when the hair clip surfaces 4A and 4B are brought into contact with each other in the state of not clipping the hair H therebetween, thespace portions 6 are formed therebetween. Therefore, the pressing force to clip the hair H is lowered, thus making it possible to slide the hair H by the appropriate friction force along the width direction of theclip portions 2. In such a way, the damage to be done to the hair H can be suppressed. - Moreover, the
space portions 6 are provided between the upper and lower hair clip surfaces 4A and 4B as described above, whereby a degree of freedom of the hair H to be clipped therebetween can be ensured appropriately. Accordingly, an effect of arranging a flow of the hair H can be further enhanced. - Furthermore, in this embodiment, the plurality of protruding/recessed portions 5 are provided on the upper and lower hair clip surfaces 4A and 4B, and the semicircular recessed
portions 5a of the upperhair clip surface 4A and the protrudingportions 5b of the lower hair clip surfaces 4B, in which the tip ends are formed into the flat shape, are brought into contact with each other, whereby thespace portions 6 are formed. Therefore, in comparison with a configuration in which the protruding/recessed portions are provided only on either one of the hair clip surfaces, surface areas of the upper and lower hair clip surfaces 4A and 4B can be increased. As described above, the surface areas of the upper and lower hair clip surfaces 4A and 4B are increased, thus making it possible to increase a supply range of thermal energy to be given to the hair. In such a way, the straight styling can be effectively given to the hair. - Note that, in this embodiment, the plurality of protruding/recessed portions 5 are provided on the upper and lower hair clip surfaces 4A and 4B, whereby the
space portions 6 are formed; however, the plurality of protruding/recessed portions 5 may be provided only on the upperhair clip surface 4A as one of the upper and lower hair clip surfaces 4A and 4B. Then, it becomes possible to form thespace portions 6 by a simple configuration in which the lowerhair clip surface 4B is a flat surface. - Moreover, the recessed
portions 5a and protrudingportions 5b of the plurality of protruding/recessed portions 5 are individually extended along the width direction of theclip portions 2, and accordingly, even if the hair H that inclines or becomes perpendicular with respect to the width direction concerned is clipped between the upper and lower hair clip surfaces 4A and 4B, the flow of the hair H can be arranged. - Furthermore, in this embodiment, the
space portions 6 formed of the plurality of protruding/recessed portions 5 are open to the both widthwise sides of theclip portions 2 in the upper and lower hair clip surfaces 4A and 4B, and accordingly, the straight styling can be given to the hair H with ease by sliding theclip portions 2 along the width direction. - Still further, in this embodiment, at least the lower hair clip surface (second hair clip surface) 4B as one of the upper and lower hair clip surfaces 4A and 4B is supported so as to be freely movable relative to the case (clip portion main body) 22. Therefore, the lower
hair clip surface 4B relatively moves in response to the amount of the clipped hair H while enhancing the adherence of the hair H onto the upper hair clip surface (first hair clip surface) 4A side on which the protruding/recessed portions 5 are formed, whereby the straight styling can be effectively given to the hair H while suppressing the damage to be done to the hair H to the minimum. - Moreover, in this embodiment, on one widthwise end of at least the upper clip portion (first clip portion) 2A as one of the upper and
lower clip portions guide protrusions 24 are provided, which are formed along the longitudinal direction of theclip portions 2, and guide the hair H along the width direction of theclip portions 2. Therefore, at the time of sliding the clipped hair H along the width direction of theclip portions 2, the hair H can be suppressed from spreading in the longitudinal direction of theclip portions 2. - In particular, in this embodiment, the
guide protrusions 24 for arranging the flow of the hair H are provided on the upper clip portion (first clip portion) 2A on a fixed side (side where the hair clip surface does not move) in which, in comparison with the case where the hair clip surface moves, the adherence is higher, and the effect of arranging the flow of the hair H can be strongly exerted. In such a way, the effect of arranging the flow of the hair H can be further enhanced. - Moreover, in accordance with this embodiment, the projections (heat radiation portions) 25 and 26 are provided on widthwise side surfaces of the upper and
lower clip portions hair iron 10, contact areas between theclip portions 2 and the scalp and skin of the user can be reduced. - Still further, in this embodiment, the heat radiation portions are the plurality of
projections clip portions 2, on at least one-side side surfaces in the width direction of the upper andlower clip portions clip portions 2 are increased, thus making it possible to efficiently radiate the heat. - The description has been made above of the preferred embodiment of the present invention; however, the present invention is not limited to the above-described embodiment, and is modifiable in various ways within the scope without departing from the spirit of the present invention. For example, in the above-described embodiment, the recessed
portions 5a of the upperhair clip surface 4A and the protrudingportions 5b of the lowerhair clip surface 4B are brought into contact with each other, whereby thespace portions 6 are formed; however, as in a modification example shown inFig. 4 , the protrudingportions 5b of the upperhair clip surface 4A and the protrudingportions 5b of the lowerhair clip surface 4B are brought into contact with each other, whereby thespace portions 30 may be formed. In this case, the recessedportions 5a of the upper and lower hair clip surfaces 4A and 4B become thespace portions 30. - Moreover, a photocatalytic function may be imparted to each of the hair clip surfaces 4. For example, as shown in
Fig. 5 , acoating material 4a containing photocatalyst particles is applied and coated on the surface of theplate portion 15a (16a) , or as shown inFig. 6 ,photocatalyst particles 4b are contained in theplate portion 15a (15a), whereby the photocatalytic function can be imparted to each of the hair clip surfaces 4. In such a manner as described above, a sterilization function, a deodorization function and the like can be imparted to the hair clip surfaces 4. - Note that, as a material that allows the hair clip surfaces 4 to exert the photocatalytic function, a publicly known material such as silver can be used; however, it is particularly preferred to use titanium dioxide. The titanium dioxide is used as described above, whereby a hydrophilic function can be imparted to the hair clip surfaces 4 by the titanium dioxide concerned, and a moist feeling and a smooth and silky feeling can be given to the hair thereby.
