Description

Technical Field

[0001] The present invention relates to a hair iron and a cover for a hair iron.

Background Art

[0002] There are variously sold beauty appliances, so-called hair irons, that can shape hair into a desired shape such as straight or curly by applying heat to the hair.

[0003] In the past, it was common for a single product of a hair iron, such as a straight iron that can straighten hair with a habit or a curling iron that can curl straight hair, to correspond to one type of use.

[0004] On the other hand, in recent years, various 2-way type hair irons that can be used for two types of uses, a straight iron and a curling iron, have been proposed.

[0005] For example, Patent Document 1 describes a hair iron that can switch functions between a straight iron by opening and closing upper and lower barrels and a curling iron by opening and closing a clip plate.

Brief Description of the Drawings

[0033] [Figure 1] It is a schematic view of a hair iron according to an embodiment of the present invention. [Figure 2] It is a perspective view of a first barrel and a second barrel according to an embodiment of the present invention. [Figure 3] It is a perspective view of a first barrel and a second barrel according to an embodiment of the present invention. [Figure 4] It is a view for explaining a first cover and a second cover according to an embodiment of the present invention. [Figure 5]This figure illustrates the first and second covers according to an embodiment of the present invention. [Modes for carrying out the invention]

[0034] Hereinafter, a hair iron X and a hair iron cover (first cover C1, second cover C2) according to an embodiment of the present invention will be described with reference to the attached drawings. Note that the embodiments shown below are examples of the present invention and the present invention is not limited to these embodiments.

[0035] As shown in Figure 1, the hair iron X comprises a first barrel 1, a second barrel 2, a hinge H, a first cover C1, and a second cover C2.

[0036] As shown in Figures 1(a) and 1(b), the first barrel 1 and the second barrel 2 are configured to be openable and closable by a hinge H. That is, Figure 1(a) shows the closed state of the hair iron X, and Figure 1(b) shows the open state of the hair iron X.

[0037] As shown in Figure 2, the first barrel 1 has a first clamping surface 11, a first winding surface 12, a clip 13, a first handle 1h, a first gripping part 1g, and a power switch S1.

[0038] The first clamping surface 11 is the heating portion of the hair iron X, and in the closed state of the hair iron X shown in Figure 1(a), it includes a flat surface that is parallel to and opposite to the second clamping surface 21 of the second barrel 2.

[0039] In other words, the first clamping surface 11, together with the second clamping surface 21, is the part of the hair iron X that performs the function of a straightener, by clamping and heating hair to make it straight.

[0040] The first winding surface 12 is the heating portion of the hair iron X, and in the closed state of the hair iron X shown in Figure 1(a), it includes a curved surface that, together with the second winding surface 22 of the second barrel 2, forms a predetermined curved shape.

[0041] For example, the first wrapping surface 12 is a curved surface that can form a semi-cylindrical shape together with the first clamping surface 11. That is, in the closed state of the hair iron X shown in Figure 1(a), the first wrapping surface 12 can form a cylindrical shape together with the second wrapping surface 22.

[0042] In other words, the first winding surface 12, formed with the second winding surface 22 to create a cylindrical shape around which hair can be wrapped and heated to create curly hair, is the part of the hair iron X that performs the function of a curling iron.

[0043] The clip 13 includes a clip body 13a, a clip lever 13b, and a clip hinge 13h. That is, by operating the clip lever 13b, the clip body 13a can be opened and closed around the clip hinge 13h as an axis.

[0044] When using the curling iron function, the clip 13 has a curved shape similar to the first wrapping surface 12, and the clip body 13a, which is formed in the same curved shape as the first wrapping surface 12, can grip the hair together with the first wrapping surface 12, thereby achieving a stronger curling iron effect.

[0045] Furthermore, the clip lever 13b of the clip 13 also serves as a fitting projection that detachably fits and secures the first fixing portion C11 of the first cover C1, which will be described later.

[0046] The first handle 1h is the part the user holds, and the user primarily uses this part to open and close the hair iron X and move it around.

[0047] The first gripping portion 1g is a non-heating portion with a shape corresponding to the second gripping portion 2g of the second barrel 2. When the user clamps hair between the first gripping surface 11 and the second gripping surface 21 (using the straightening iron function), they can press the first gripping portion 1g and the second gripping portion 2g together to press the first gripping surface 11 and the second gripping surface 21 firmly against the hair, thereby obtaining a stronger straightening iron effect.

[0048] Furthermore, when the user wraps hair around the cylindrical shape formed by the first wrapping surface 12 and the second wrapping surface 22 (using the curling iron function), holding the first gripping part 1g and the second gripping part 2g makes it easier to move the hair iron X, thus making the curling iron function easier to use.

[0049] The power switch S1 is a switch that can turn the power of the hair iron X on and off. The power switch S1 may be located on the second barrel 2 instead of the first barrel 1.

[0050] As shown in Figure 3, the second barrel 2 has a second clamping surface 21, a second wrapping surface 22, a projection 23, a second handle 2h, a second gripping part 2g, and an on / off switch S2.

[0051] The second clamping surface 21 is the heating portion of the hair iron X, and in the closed state of the hair iron X shown in Figure 1(a), it includes a flat surface that is parallel to and opposite to the first clamping surface 11 of the first barrel 1.

[0052] In other words, the second clamping surface 21, together with the first clamping surface 11, clamps hair and heats it to straighten it, and is the part of the hair iron X that performs the function of a straightener.

[0053] The second winding surface 22 is the heating portion of the hair iron X, and in the closed state of the hair iron X shown in Figure 1(a), it includes a curved surface that forms a predetermined curved shape together with the first winding surface 12 of the first barrel 1.

[0054] For example, the second wrapping surface 22 is a curved surface that can form a semi-cylindrical shape together with the second clamping surface 21. That is, in the closed state of the hair iron X shown in Figure 1(a), the second wrapping surface 22 can form a cylindrical shape together with the first wrapping surface 12.

[0055] In other words, the second winding surface 22 is the part of the hair iron X that performs the function of a curling iron, allowing hair to be wrapped around the cylindrical shape formed with the first winding surface 12 and heated to create curly hair.

[0056] When the hair iron X is placed with the projection 23 facing downwards, the heating element (especially the second wrapping surface 22) can be separated from the surface being placed on. In other words, the hair iron X, which is still hot after use, can be placed and cooled relatively safely by the projection 23.

[0057] Furthermore, the projection 23 also serves as a fitting projection that detachably fits and secures the second fixing portion C21 of the second cover C2, which will be described later.

[0058] The second handle 2h is the part the user holds, and the user primarily uses this part to open and close the hair iron X and move it around.

[0059] The second gripping portion 2g is a non-heating portion with a shape corresponding to the first gripping portion 1g of the first barrel 1.

[0060] When the user clamps hair between the first clamping surface 11 and the second clamping surface 21 (using the straightening iron function), they can press the first gripping part 1g and the second gripping part 2g together to press the first clamping surface 11 and the second clamping surface 21 firmly against the hair, thereby obtaining a stronger straightening iron effect.

[0061] Furthermore, when the user wraps hair around the cylindrical shape formed by the first wrapping surface 12 and the second wrapping surface 22 (using the curling iron function), holding the first gripping part 1g and the second gripping part 2g makes it easier to move the hair iron X, thus making the curling iron function easier to use.

[0062] As shown in Figure 3, recesses G are provided at the ends of the first barrel 1 and the second barrel 2, that is, at the ends of the first gripping portion 1g and the second gripping portion 2g.

[0063] The recess G can be detachably fitted and fixed to the first fixing auxiliary part C12 of the first cover C1 or the second fixing auxiliary part C22 of the second cover C2, which will be described later.

[0064] The on / off switch S2 is a switch that can switch the open / closed state (straightening iron and curling iron function) of the hair iron X. The on / off switch S2 may be located on the first barrel 1 instead of the second barrel 2.

[0065] As shown in Figure 4, the first cover C1 has a first fixing part C11 and a first fixing auxiliary part C12.

[0066] The first fixing portion C11 includes an annular portion shaped to correspond to the clip lever 13b, and the first fixing auxiliary portion C12 includes a convex portion shaped to correspond to the recess G.

[0067] Specifically, as shown by the dashed line in Figure 4, the first cover C1 is fitted and fixed to the first barrel 1 by inserting the clip lever 13b into the first fixing part C11 and inserting the first fixing auxiliary part C12 into the recess G of the first barrel 1 (see also Figure 5).

[0068] The first cover C1, which is fitted and fixed to the first barrel 1, can cover the first wrapping surface 12 while leaving the first clamping surface 11 open. Furthermore, by fitting and fixing the first cover C1 to the first barrel 1, the clip lever 13b can be fixed to the first wrapping surface 12.

[0069] When considering the relative movement between the first barrel 1 and the first cover C1 fitted and fixed to the first barrel 1, the direction D11 in which movement is suppressed due to fixing by the first fixing part C11 and the direction D12 in which movement is suppressed due to fixing by the first fixing auxiliary part C12 are different from each other.

[0070] As an example, in the first cover C1 fitted and fixed to the first barrel 1, the insertion direction of the clip lever 13b into the first fixing part C11 and the insertion direction of the recess G at the end of the first barrel 1 into the first fixing auxiliary part C12 are different from each other. Therefore, the first cover C1 is less likely to fall off the first barrel 1.

[0071] Furthermore, the first cover C1 is entirely made of heat-resistant silicone rubber, possessing heat resistance and appropriate elasticity and flexibility.

[0072] In other words, when a user intentionally attaches or detaches the first cover C1 to the first barrel 1, they can easily do so by slightly stretching the first cover C1 or by utilizing the elasticity and flexibility of the first cover C1.

[0073] As shown in Figure 5, the second cover C2 has a second fixing part C21 and a second fixing auxiliary part C22.

[0074] The second fixing portion C21 includes a concave portion on the inner surface of the second cover C2 that corresponds to the projection 23, and the second fixing auxiliary portion C22 includes a convex portion that corresponds to the concave portion G.

[0075] Furthermore, the concave portion on the inner surface of the second cover C2 that corresponds to the projection 23 may include a convex portion on the outer surface of the second cover C2 that corresponds to the projection 23.

[0076] Specifically, as shown by the dashed line in Figure 5, the second cover C2 is fitted and fixed to the second barrel 2 by inserting the projection 23 into the second fixing part C21 and inserting the second fixing auxiliary part C22 into the recess G of the second barrel 2 (see also Figure 4).

[0077] The second cover C2, which is fitted and fixed to the second barrel 2, can cover the second wrapping surface 22 while leaving the second clamping surface 21 open.

[0078] When considering the relative movement between the second barrel 2 and the second cover C2 fitted and fixed to the second barrel 2, the direction D21 in which movement is suppressed due to fixing by the second fixing part C21 and the direction D22 in which movement is suppressed due to fixing by the second fixing auxiliary part C22 are different from each other.

[0079] As an example, in the second cover C2 fitted and fixed to the second barrel 2, the direction in which the projection 23 is fitted into the second fixing portion C21 and the direction in which the recess G at the end of the second barrel 2 is fitted into the second fixing auxiliary portion C22 are different. Therefore, the second cover C2 is less likely to fall off the second barrel 2.

[0080] Furthermore, the second cover C2 is entirely made of heat-resistant silicone rubber, possessing heat resistance and appropriate elasticity and flexibility.

[0081] In other words, when a user intentionally attaches or detaches the second cover C2 to the second barrel 2, they can easily do so by slightly stretching the second cover C2 or by utilizing the elasticity and flexibility of the second cover C2.

[0082] <Effects of this embodiment> In the hair iron X of this embodiment, the first cover C1 is configured to cover the first wrapping surface 12 while leaving the first clamping surface 11 open, and the second cover C2 is configured to cover the second wrapping surface 22 while leaving the second clamping surface 21 open. Therefore, in the 2-way type hair iron X, the straightening function can be used more safely than in conventional models.

[0083] Furthermore, since the first cover C1 is configured to securely fix the clip body 13a, it suppresses unintended movement of the clip 13 when using the straightening iron function, allowing for safer use of the straightening iron function.

[0084] Furthermore, since the first cover C1 has a first fixing part C11 that is detachably fixed to the clip lever 13b, the first cover C1 can be easily fixed to the hair iron X without significantly changing the design of the hair iron X.

[0085] Furthermore, the first cover C1 has a first fixing auxiliary part C12 that is detachably fixed to a recess G at the end of the first barrel 1. In relative movement between the first barrel 1 and the first cover C1, the direction D11 in which movement is suppressed based on fixing by the first fixing part C11 and the direction D12 in which movement is suppressed based on fixing by the first fixing auxiliary part C12 are different from each other. As a result, the first cover C1 is less likely to fall off the first barrel 1, and the straight iron function can be used more safely.

[0086] Furthermore, the first fixing portion C11 is configured to allow the clip lever 13b to be fitted into it, and the first fixing auxiliary portion C12 is configured to fit into the recess G at the end of the first barrel 1. Since the direction in which the clip lever 13b is fitted into the first fixing portion C11 and the direction in which the recess G fits into the first fixing auxiliary portion C12 are different, it is possible to make the first barrel 1 and the first cover C1 detachable with a relatively simple configuration while suppressing the first cover C1 from falling off the first barrel 1.

[0087] Furthermore, the second cover C2 has a second fixing part C21 that is detachably fixed to the second barrel 2, and a second fixing auxiliary part C22 that is detachably fixed to a recess G at the end of the second barrel 2. In the relative movement of the second barrel 2 and the second cover C2, the direction D21 in which movement is suppressed based on fixing by the second fixing part C21 and the direction D22 in which movement is suppressed based on fixing by the second fixing auxiliary part C22 are different from each other. Therefore, while the second barrel 2 and the second cover C2 are detachable, the second cover C2 is prevented from falling off the second barrel 2, allowing for safer use of the straightening iron function.

[0088] Furthermore, the second barrel 2 has a fitting portion (projection 23) that detachably fits with the second fixing portion C21, and the second fixing auxiliary portion C22 is configured to fit with a recess G at the end of the second barrel 2. Since the fitting direction of the fitting portion (projection 23) to the second fixing portion C21 and the fitting direction of the recess G to the second fixing auxiliary portion C22 are different from each other, it is possible to make the second barrel 2 and the second cover C2 detachable with a relatively simple configuration while suppressing the detachment of the second cover C2 from the second barrel 2.

[0089] Furthermore, because the fitting portion includes the projection 23, when the hair iron X is placed with the projection 23 facing downwards, the heating element can be separated from the mounting surface. In other words, the hair iron X, which is still hot after use, can be placed and cooled relatively safely by the projection 23.

[0090] Furthermore, since the second fixing part C21 includes a concave portion on the inner surface of the second cover C2 that corresponds to the projection 23, and a convex portion on the outer surface of the second cover C2 that corresponds to the projection 23, the hair iron X with the second cover C2 attached can be placed with the convex portion facing downwards, thereby covering the heating element while keeping it separated from the mounting surface. In other words, the hair iron X, which is hot after use, can be placed and the heat can be dissipated more safely.

[0091] The first cover C1 and / or the second cover C2 of this embodiment allow for safer use of the straightening function of the 2-way (straightening and curling) type hair iron X.

[0092] It should be noted that the configurations and functions shown in the above embodiments are merely examples and can be modified in various ways based on design requirements, etc. [Explanation of Symbols]
