Description

Hair curler

Technical Field

The present invention relates to hair curlers.

Background

Among hair curlers, there are a heat generation type hair curler having a heating element inside (patent document 1: japanese patent No. 2919028), a heat storage type hair curler heating by a heating device provided separately from the hair curler (patent documents 2 to 4: japanese patent No. 3590145, japanese patent registration No. 3151847, and japanese patent application laid-open No. 2006 and 6687), and the like. The user can style the hair into a curly shape by winding the hair around the body part of the curler thus warmed and fixing the hair to the head part so as to prevent the hair from falling off by the hair clip or the like, and then, allowing the curler to stand for a period of several minutes to several tens of minutes (sometimes overnight) until the curler is naturally cooled.

Thus, unlike the hair iron of the type in which the handle is operated, the hair iron fixable to the head has an advantage that the hair iron can be styled by makeup time, changing time, bedtime, and the like because the user is in a hands-free state during the standing time in natural cooling. Moreover, since hands are not required, the duration of curling is also easily extended by extending the standing time. Further, the hair curler is advantageous in that even if the hair is long, it is possible to shape a bundle of hair from the root to the tip at the same time, and therefore it is efficient, and it is also possible to wind a bundle of hair from the root to the tip in a "spiral shape" instead of a "spiral shape", and therefore it is possible to realize natural curls (curls close to natural curls) in which the curvature gradually decreases from the root to the tip.

Here, for example, when the root of the hair at the top of the head rises and gives a voluminous feeling, or when the hair is curled up by the bang and left or right, the diameter ratio is suitable for a hair curler having a large diameter. On the other hand, a hair curler having a relatively small diameter is suitable for a case where a hair is curled to make the periphery of the face gorgeous by adding curls to "back hair" from which hair falls when the hair is pricked back. In addition, it is known that the thickness of a curling iron required for curling hair varies depending on the hairstyle and the length of hair (e.g., long hair and half-long hair). Therefore, a user who desires to use the hair curler for these various uses needs to prepare a plurality of hair curlers having different diameters and thicknesses.

However, for example, a heating-type curling iron is expensive compared to a curling iron having no heating function, and thus it is inefficient to have a plurality of curling irons, and in a heating-type curling iron requiring a separate heating device, if the diameter size is changed to be increased, the size of the heating device (i.e., a housing) becomes large, and transportation becomes inconvenient, so that there are not many users who purchase and stock a plurality of kinds of curling irons on purpose. In particular, since a user who has a hair iron at home often carries the hair iron for styling while going out, it is strongly desired to miniaturize the heating type hair iron as much as possible.

Patent documents 5 and 6 (japanese patent No. 6352538 and 6041153) disclose hair irons having a variable diameter of a cylindrical member as a heating element. With this hair iron, it is possible to transfer a coarse curl to hair and also to transfer a fine curl to hair. Therefore, it is also considered that the above-mentioned problems can be solved by applying the mechanism of the hair iron to the hair iron.

However, the hair curlers that can be fixed to the head are completely different from hair irons of the type that operate the handle in convenience of use. Therefore, when the mechanism of the hair iron of patent documents 5 and 6 is applied to a hair iron, it is desirable that the mechanism for expanding and contracting the diameter of the body portion does not become an obstacle when the hair iron is fixed to the head portion. Further, if the hair curler can be easily purchased in a drug and cosmetic store, a convenience store, or the like, the operation for expanding and contracting the diameter of the main body portion should be as intuitively and easily understood as possible.

SUMMERY OF THE UTILITY MODEL

Accordingly, an object of the present invention is to provide a curling iron in which a diameter of a hair winding portion is variable and which is convenient to use.

In order to solve the above problems, the present invention provides a hair curler capable of changing a diameter size between a large diameter state and a small diameter state, the hair curler having a cylindrical body part sandwiched between a flange-shaped top cover and a flange-shaped bottom cover, the body part comprising: a pair of half-cylinder bodies that are relatively displaced by relatively rotating the top cover and the bottom cover, and that are switched between a small-diameter state in which the cylinders are formed in a manner facing each other without a gap, and a large-diameter state in which at least one of the side edges is separated to form a gap; and a filling member which is displaced by relatively rotating the top cover and the bottom cover, and which is accommodated in the cylinder when the pair of half cylinders are in the small diameter state, and which is filled in the gap when the pair of half cylinders are in the large diameter state.

In one embodiment, an upper protruding part and a lower protruding part are respectively arranged on the upper end part and the lower end part of at least one half-cut cylinder body; and an upper protrusion and a lower protrusion are respectively provided on an upper end portion and a lower end portion of the packing body, a guide plate having a first upper guide groove for guiding the movement of the upper protrusion of the half-cut cylinder and a second upper guide groove for guiding the movement of the upper protrusion of the packing body is disposed on the top cover, and a guide plate having a first lower guide groove for guiding the movement of the lower protrusion of the half-cut cylinder and a second lower guide groove for guiding the movement of the lower protrusion of the packing body is disposed on the bottom cover.

In one embodiment, there are stops for maintaining the small diameter state and the large diameter state, respectively.

In one embodiment, a face fastener is disposed on a surface of each of the pair of half cylinders.

In one embodiment, a heat generating body is disposed inside the main body.

In one embodiment, there is a hair clip that presses hair wound around the body portion.

In one embodiment, an insertion opening of a power cord is arranged on the side surface of the top cover, a heating element is arranged in the main body, and the power cord supplies power to the heating element through the insertion opening to heat the main body.

According to the hair curler of the present invention, the user can slightly grip the flange-shaped top cover and the flange-shaped bottom cover with the right and left hands, and can relatively rotate the top cover and the bottom cover by slightly twisting the wrists in opposite directions, thereby switching the diameter of the main body between the large diameter state and the small diameter state. Further, even if the user does not read the specification, the flange-like top cover and the flange-like bottom cover can be easily found to be relatively rotatable while the user slightly touches the hair curler while holding the hair curler with the hand, and the diameter of the main body portion is changed by the rotation. In addition, when the hair is wound around the hair curler, the hair can be wound around the main body portion with one hand while rotating the flange-shaped top cover or the flange-shaped bottom cover while holding the flange-shaped top cover or the flange-shaped bottom cover with one hand. Further, after the hair curler is fixed to the head, there is no risk of falling off or causing pain to the scalp when the user turns over, because there are no excess projections or the like on the surface of the hair curler, and sleep is not hindered. Therefore, the present invention has an effect of providing a curling iron in which the diameter of the hair winding part is variable and which is convenient to use.

Detailed Description

Hereinafter, an embodiment of a curling iron according to the present invention will be described with reference to the accompanying drawings.

Fig. 1 is a perspective view of the hair curler according to the present embodiment in a small diameter state, and fig. 2 is a perspective view of the hair curler according to the present embodiment in a large diameter state. As shown in fig. 1 and 2, the curling iron 100 of the present embodiment is a curling iron in which a cylindrical body part 124 can be changed between a small diameter state (fig. 1) and a large diameter state (fig. 2), and the body part 124 is sandwiched between a resin flange-shaped top cover 1 and a resin flange-shaped bottom cover 2. The "flange-like lid" referred to herein is a substantially disk-like lid having a diameter equal to or slightly larger than the diameter of the main body 124 in the large diameter state. In the present embodiment, the diameter size is 26mm in the small diameter state and 32mm in the large diameter state, but the present invention is not limited thereto.

The main body 124 has a pair of half-cut cylindrical bodies 5 and 6 made of resin that are relatively displaced by relatively rotating the top cover 1 and the bottom cover 2, and hook surfaces 24 of surface fasteners for winding hair are disposed on the surfaces of the half-cut cylindrical bodies 5 and 6, respectively.

Hereinafter, the operation of each part will be described assuming that the direction from the bottom cover 2 to the top cover 1 is an upward direction and the bottom cover 2 positioned below is fixed. In the hair curler 100 of the present embodiment, one of the half-cutting roller bodies 5 is fixed to the bottom cover 2 side, while the top cover 1 side is rotatable in the direction a of fig. 1, and the other half-cutting roller body 6 is displaceable in position as the top cover 1 rotates. By the displacement of the half-cut cylindrical body 6, the main body 124 is switched between a small diameter state (fig. 1) in which the pair of half-cut cylindrical bodies 5 and 6 face each other without a gap to form a cylinder, and a large diameter state (fig. 2) in which the side edges 5E and 6E of the half-cut cylindrical bodies 5 and 6 are separated from each other to form a gap G.

A partially cylindrical resin filler 7 (see fig. 2) is disposed inside the body portion 124. The filler 7 is movable (displaceable) in the radial direction in accordance with the rotation of the overcap 1, and is accommodated in the cylindrical body 124 when the body 124 is in a small-diameter state (the state of fig. 1), and is filled to fill the gap G when the body 124 is in a large-diameter state (the state of fig. 2). In this large diameter state, the side surface of the filler 7 and the side surfaces of the pair of half- cylindrical bodies 5 and 6 form a substantially cylindrical side surface as a whole.

Fig. 3 is an exploded view of the hair curler according to the present embodiment. As shown in fig. 3, a resin rotary shaft 13 for connecting the top cover 1 and the bottom cover 2 and a heating element 125 are disposed inside the body 124. The rotation shaft 13 is fixed to the top cover 1 side and rotates together with the top cover 1. Further, inside the top cover 1, the circuit board 31 and the 2 resin guide plates 9 and 4 are arranged to be overlapped from above, and inside the bottom cover 2, a resin guide plate 5A integrally formed at the lower end of the half-cut cylinder 5 and a resin guide plate 8 provided separately from the guide plate 5A are arranged to be overlapped from above.

The upper guide grooves 9U and 4U are provided in the guide plates 9 and 4 disposed inside the top cover 1, respectively. These upper guide grooves 9U and 4U are provided to guide the movement of an upper protrusion 6U provided at the upper end of the half-cut cylinder 6 and an upper protrusion 7U provided at the upper end of the filler 7 (described later in detail).

On the other hand, the lower guide grooves 5L, 8L are provided in the guide plates 5A, 8 disposed inside the bottom cover 2, respectively. These lower guide grooves 5L, 8L are provided to guide the movement of a lower protrusion 6L provided at the lower end of the half-cut cylinder 6 and a lower protrusion 7L provided at the lower end of the filler 7 (described later in detail).

Further, a heating element 125 is attached to the periphery of the rotating shaft 13 disposed inside the body portion 124 via a screw and a plate, not shown. The heating element 125 has a thermal fuse, a thermostat, a heating wire, and the like, and is connected to the circuit board 31 in the top cover 1 via a lead wire not shown.

Here, an unillustrated inlet (port) for a power supply line such as a USB data line is formed in a side surface of the top cover 1. When power is supplied to the circuit board 31 from the outside via the power supply line inserted into the insertion port, the light emitting portion 1A provided on the upper surface of the top cover 1 is lit in red. Then, the electric power supplied from the outside is supplied to the heating wire 29 via the circuit board 31, and the temperature of the heating element 125 starts to rise. After that, when the temperature of the heating element 125 reaches the appropriate temperature range (for example, about 100 ℃) after a lapse of several minutes, the color of the light emitting section 1A is switched to blue, and temperature control (on/off control by the thermostat 22) is performed so that the temperature of the heating element 125 is maintained in the appropriate temperature range. When power supply from a power supply line, not shown, is stopped, light emitting unit 1A is turned off, and heating element 125 is naturally cooled.

The user connects one end of the power cord to the insertion port of the top cover 1 and connects the other end of the power cord to a power supply device (an adapter, a USB port of a PC, or the like), and then the light-emitting unit 1A is lit in red to confirm the start of power supply. After that, after waiting for several minutes, when it is confirmed that the color of light emitting section 1A of top cover 1 has changed to blue, the power cord is removed from the insertion opening of top cover 1. In this state, the body portion 124 of the curling iron 100 is heated to about 100 ℃. Thereafter, the user winds the hair around the body portion 124 of the hair curler 100 and fixes the hair on his or her head by a hair clip or the like, not shown. Thereafter, a cooling period (several minutes to several tens of minutes, or one night) is waited until the temperature of the curler 100 returns to the normal temperature. Thereafter, the hair clip is removed from the hair curler 100 at room temperature, and the hair is wound. In this state, the curl shape is transferred to the hair.

Fig. 4(a) is a perspective view illustrating the guide plate rotating together with the top cover, and fig. 4(B) is a perspective view illustrating the guide plate fixed to the bottom cover side.

As shown in fig. 4(a), the guide plate 9 disposed on the upper side of the top cover 1 is fixed to the guide plate 8 disposed on the lower side of the bottom cover 2 via a rotating shaft 13. Therefore, when the top cover 1 is rotated, the components shown in fig. 4(a) are rotated as one body.

As shown in fig. 4(B), the guide plate 4 disposed on the lower side of the top cover 1 and the guide plate 5A disposed on the upper side of the bottom cover 2 are fixed to the bottom cover 2 side together with the half-cut cylinder 5. Therefore, even if the top cover 1 is rotated, the components shown in fig. 4(B) are still fixed to the bottom cover 2.

Therefore, when the top cover 1 is rotated, the guide plates 9 and 4 superposed and arranged in the top cover 1 are relatively rotated so as to slide with each other, and the guide plates 5A and 8 superposed and arranged in the bottom cover 2 are relatively rotated so as to slide with each other.

Here, the guide plate 9 is provided with a first upper guide groove 9U-1 for guiding the movement of the upper protrusion 6U (fig. 3) of the half-cut cylinder 6 and a second upper guide groove 9U-2 for guiding the movement of the upper protrusion 7U (fig. 3) of the packing 7.

The guide plate 4 is also provided with a first upper guide groove 4U-1 for guiding the movement of the upper protrusion 6U of the half-cut cylinder 6 and a second upper guide groove 4U-2 for guiding the movement of the upper protrusion 7U of the filler 7.

Therefore, the position of the upper projecting portion 6U of the half-cut cylinder 6 is restricted by the relative positions of the first upper guide groove 9U-1 and the first upper guide groove 4U-1 of these guide plates 9, 4, and the position of the upper projecting portion 7U of the packing body 7 is restricted by the relative positions of the second upper guide groove 9U-2 and the second upper guide groove 4U-2 of the guide plates 9, 4.

On the other hand, the guide plate 8 is provided with a first lower guide groove 8L-1 for guiding the movement of the lower protrusion 6L (fig. 3) of the half-cut cylinder 6 and a second lower guide groove 8L-2 for guiding the movement of the lower protrusion 7L (fig. 3) of the packing 7.

The guide plate 5A is also provided with a first lower guide groove 5L-1 for guiding the movement of the lower protrusion 6L of the half-cut cylindrical body 6 and a second lower guide groove 5L-2 for guiding the movement of the lower protrusion 7L of the filler 7.

Therefore, the position of the lower protrusion 6L of the half-cut cylinder 6 is regulated by the relative positions of the first lower guide groove 8L-1 and the first lower guide groove 5L-1 of these guide plates 8, 5A, and the position of the lower protrusion 7L of the filler 7 is regulated by the relative positions of the second lower guide groove 8L-2 and the second lower guide groove 5L-2 of the guide plates 8, 5A.

Reference numerals 4U-1 'and 5L-1' in fig. 4B denote circular holes for rotatably supporting the upper protrusion 6U '(fig. 3) and the lower protrusion 6L' (fig. 3) provided at the side edges of the half-cylindrical body 6.

When the guide plates 9 and 4 disposed on the upper side are rotated relative to each other and the guide plates 5A and 8 disposed on the lower side are rotated relative to each other, the upper protrusions 6U and 7U and the lower protrusions 6L and 7L engaged with the guide grooves 9U, 4U, 5L and 8L are moved in a predetermined direction, and therefore, the half-cut cylinder 6 and the filler 7 are displaced as described below.

Fig. 5(a) is a schematic plan view of the hair curler in a small diameter state with the top cover removed, and fig. 5(B) is a schematic plan view of the hair curler in a large diameter state with the top cover removed. In fig. 5, the guide plate, the heating element, and the rotating shaft are not shown in order to facilitate understanding of the operation of the movable portion.

First, when the top cover 1 of fig. 1 is rotated in the direction of arrow a (from the state of fig. 5(a) to the state of fig. 5 (B)), the upper protrusion 6U provided at the center upper end of the half-cut cylinder 6 is guided in the direction of arrow C. At this time, the posture of the entire half-cut cylindrical body 6 is changed so as to open to the outer circumferential side with the upper protrusion 6U 'provided on the side end edge 6E' of the half-cut cylindrical body 6 as a fulcrum, and therefore, the side end edge 6E of the half-cut cylindrical body 6 is separated from the side end edge 5E of the half-cut cylindrical body 5 to form the gap G. Although not shown, the lower projecting portion 6L on the lower end side of the half-cut cylindrical body 6 is also guided in the same manner as the upper projecting portion 6U, and the lower projecting portion 6L 'on the lower end side of the half-cut cylindrical body 6 is also pivotally supported in the same manner as the upper projecting portion 6U'.

When the top cover 1 of fig. 1 is rotated in the direction of arrow a (from the state of fig. 5a to the state of fig. 5B), the upper protrusion 7U provided at the center upper end of the filling body 7 is guided in the direction of arrow D, and therefore the entire filling body 7 moves from the inside of the main body portion 124 toward the outer peripheral side, and fills the gap G. Although not shown, lower protrusion 7L on the lower end side of filler 7 is also guided in the same manner as upper protrusion 7U.

Fig. 6(a) and 6(B) are explanatory views of the stopper. The hair curler 100 of the present embodiment has stoppers for holding the small diameter state and the large diameter state, respectively. The stopper is constituted by a combination of a rib 1R (fig. 6(a)) provided on the inner side wall of the rotatable top cover 1 and two ribs 4R, 4R (fig. 6(B)) provided around the fixed guide plate 4. The top cover 1 is disposed around the guide plate 4 such that the rib 1R in fig. 6(a) is located between the ribs 4R and 4R in fig. 6 (B). Therefore, when the top cover 1 is rotated, the rib 1R of the top cover 1 moves between the ribs 4R, 4R of the guide plate 4. Further, when the rib 1R of the top cover 1 passes over one rib 4R of the guide plate 4, the large diameter state is maintained, and when the rib 1R of the top cover 1 passes over the other rib 4R of the guide plate 4, the small diameter state is maintained. Therefore, the user can hold the top cover 1 and the bottom cover 2 with the right and left hands, respectively, and can rotate the wrists to apply a force until a click sound is generated, thereby fixing the main body 124 in a small diameter state or a large diameter state. The fixing can be released by twisting the wrists to the opposite sides thereof and applying a force until a click sound is generated again.

Fig. 7(a) is a perspective view showing a state in which the hair clip is attached to the hair curler, and fig. 7(B) is an exploded view of the hair clip. As shown in fig. 7, the hair curler 100 of the present embodiment has a hair clip 200 for pressing hair wound around the body portion 124. The hair clip 200 is formed by connecting the upper hair clip 11 and the lower hair clip 12 by the spring 32, and the upper hair clip 11 and the lower hair clip 12 are formed in a curved shape (a curved thick-toothed comb shape) along the body portion 124 so as not to hinder the hair curler 100 from being fixed to the head of the user. Such a hair clip 200 can press the hair wound around the body portion 124 with appropriate strength by the elastic force of the spring 32. The strength of the elastic force of the spring 32 is adjusted in advance so that the body 124 can press hair with appropriate strength in both the large diameter state and the small diameter state.

As described above, according to the hair curler 100 of the present embodiment, the user can slightly grip the flange-shaped top cover 1 and the flange-shaped bottom cover 2 with the left and right hands, and can relatively rotate the top cover 1 and the bottom cover 2 by slightly twisting the wrists in opposite directions, thereby switching the diameter of the body 124 between the large diameter state (fig. 2) and the small diameter state (fig. 1). Further, even if the user does not read the specification, the flange-like top cover 1 and the flange-like bottom cover 2 can be easily found to be relatively rotatable while the user slightly touches the hair curler 100 by holding it with the hand, and the diameter of the main body portion 124 is changed by the rotation. In addition, when hair is wound around the hair curler 100, the flange-shaped top cover 1 or the flange-shaped bottom cover 2 can be gripped with one hand and the hair can be wound around the main body portion 124 with the other hand while rotating the same, so that the winding operation is easy. Further, after the hair curler 100 is fixed to the head, there is no risk of falling off or causing pain to the scalp when turning over, because there are no excessive projections or the like on the surface of the hair curler 100.

Although an example of the present invention has been described above, the above-described configuration may be modified as appropriate within a range that does not impair the function of the hair curler.
