[Diagram 5] FIG. 13 is a perspective view showing the outer shape of a modified example of a hair iron. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. [1. Configuration] As shown in FIGS. 1 to 4, a hair iron 1 of the embodiment includes a main body case 2, a sliding member 3, and a trigger member 4.

[0010] The main body case 2 includes a rectangular portion 21, a trapezoidal portion 22, and a main body side plate 23. The rectangular portion 21 has an external shape like a rectangular plate. In the following, the longitudinal direction of the rectangular portion 21 is defined as the X-axis direction, the lateral direction of the rectangular portion 21 as the Y-axis direction, and the thickness direction perpendicular to both the X-axis direction and the Y-axis direction as the Z-axis direction. The rectangular portion 21 is set, for example, to have a length in the X-axis direction of about 90 mm, a length in the Y-axis direction of about 50 mm, and a length in the Z-axis direction of about 11 mm.

[0011] The trapezoidal portion 22 is provided at one end in the X-axis direction of the rectangular portion 21. The trapezoidal portion 22 is formed so that its size in the Y-axis direction and the Z-axis direction increases as it moves away from the rectangular portion 21.

[0012] The rectangular portion 21 and the trapezoidal portion 22 are made of, for example, a material with low thermal conductivity. The rectangular portion 21 and the trapezoidal portion 22 may be integrally formed. Furthermore, the rectangular portion 21 and the trapezoidal portion 22 may be formed to be detachable.

[0013] In the rectangular portion 21, the slide member 3 is held at the end opposite to the side where the trapezoidal portion 22 is provided. Hereinafter, in the rectangular portion 21, the surface where the slide member 3 is held is referred to as a head surface 2a. The rectangular portion 21 has a through hole 2b in the center. In other words, the rectangular portion 21 is formed in a ring shape.

[0014] The head surface 2a of the rectangular portion 21 has an outwardly convex curved shape. The head surface 2a has an opening 2c at one end in the Y-axis direction, which communicates with the storage space inside the rectangular portion 21 and is formed to hold the slide member 3.

[0015] The body side plate 23 is provided on the head surface 2a in a portion other than the opening 2c. The body side plate 23 is a plate-shaped heating element that generates heat when electricity is applied. The body side plate 23 has a curved shape that fits the head surface 2a.

[0016] The slide member 3 includes a holding plate 31 , a support 32 , and a slide side plate 33 . The holding plate 31 is a plate-like member having a curved shape similar to the head surface 2a. The support pillar 32 is a columnar member that extends from one end in the Y-axis direction of the holding plate 31 and has a thickness that allows it to be inserted and removed from the opening 2c of the head surface 2a. The thickness of the support pillar 32 refers to the width in the Y-axis direction and the Z-axis direction.

[0017] The holding plate 31 and the support pillars 32 are made of, for example, a material with low thermal conductivity. The slide-side plate 33 is provided on the surface of the holding plate 31 facing the head surface 2a. The slide-side plate 33 is a plate-shaped heating element that generates heat when electricity is applied, similar to the body-side plate 23. The slide-side plate 33 has a curved shape that fits the opposing surface of the holding plate 31.

[0018] The slide member 3 is attached to the main body case 2 so as to be movable forward and backward along the X-axis direction between a slide standby position shown in Figures 1 and 3 and a slide storage position shown in Figures 2 and 4. The slide standby position is a position where the slide member 3 protrudes from the head surface 2a, so that the main body side plate 23 provided on the head surface 2a and the slide side plate 33 provided on the holding plate 31 face each other with a gap therebetween. The slide storage position is a position where the entire support 32 is stored in the main body case 2, so that the main body side plate 23 and the slide side plate 33 are in contact with each other.

[0019] The trigger member 4 has a columnar operating part 4a exposed at the through hole 2b of the main body case 2. The trigger member 4 is attached to the main body case 2 so as to be movable forward and backward along the X-axis direction between a trigger standby position shown in Figs. 1 and 3 and a trigger storage position shown in Figs. 2 and 4. At the trigger standby position, the operating part 4a is located near the center of the through hole 2b in the X-axis direction. At this time, the distance between the end of the operating part 4a on the head surface 2a side (hereinafter, the operating upper end) and the surface facing the operating upper end of the through hole 2b is large enough to allow at least one finger of the user to be inserted therethrough.

[0020] At the trigger stored position, the operation part 4a is located at a position moved within the through hole 2b from the trigger standby position toward the trapezoidal part 22 by the length from the slide standby position to the slide stored position of the sliding member 3. When the operation part 4a is at the trigger stored position, a part or the whole of the operation part 4a may be configured to be stored in the main body case 2.

[0021] The main body case 2 has two side surfaces located at both ends in the Y-axis direction, and on one of these side surfaces, a power / temperature setting button 5, a charging port 6, and an unlock button 7 are provided. The power / temperature setting button 5 is provided to control the power supply to the main body side plate 23 and the slide side plate 33. The power / temperature setting button 5 is configured not only to turn the power on and off, but also to switch the set temperature of the main body side plate 23 and the slide side plate 33 to a low temperature (e.g., 140°C) or a high temperature (e.g., 180°C) when the power is on. For example, the power / temperature setting button 5 may be configured to switch in the following order every time it is pressed: power off → power on → low temperature → high temperature → power off. Also, the power / temperature setting button 5 may be configured to switch between power off and power on every time it is pressed for a long time, and to switch between low temperature and high temperature every time it is pressed for a short time.

[0022] The charging port 6 is, for example, a USB connector, and a USB cable connected to an external power source is attached and detached. The lock release button 7 is operated to release the locked state in which the trigger member 4 is held in the trigger stored position.

[0023] As shown in FIGS. 2 and 4, the main body case 2 includes a guide portion 11, a biasing member 12, a locking mechanism 13, a battery 14, and a heating circuit 15 therein. The support pillar 32 of the slide member 3 and the trigger member 4 are connected inside the main body case 2 so as to operate as one unit. That is, when the slide member 3 is in the slide standby position, the trigger member 4 is in the trigger standby position, and when the slide member 3 is in the slide stored position, the trigger member 4 is connected so as to be in the trigger stored position. Hereinafter, the slide standby position and the trigger standby position are collectively referred to as standby positions, and the slide stored position and the trigger stored position are collectively referred to as stored positions.

[0024] The guide portion 11 forms a space for accommodating the integral support post 32 and trigger member 4, and holds the support post 32 and trigger member 4 movably along the X-axis direction. The guide portion 11 may include a structure for restricting the movement of the slide member 3 and the trigger member 4 so that they do not move beyond the standby position. Here, when the trigger member 4 is in the standby position, the end of the head surface 2a side of the trigger member 4 abuts against the inner wall of the main body case 2 that forms the guide portion 11, thereby restricting the movement of the trigger member 4.

[0025] The biasing member 12 is made of an elastic member such as a spring, and biases the slide member 3 and the trigger member 4 from the stored position toward the standby position. In other words, when no external force is applied to the slide member 3 and the trigger member 4, the biasing force of the biasing member 12 and the structure of the guide part 11 hold the slide member 3 and the trigger member 4 in the standby position.

[0026] When the trigger member 4 is moved to the stored position by an external force operating the operating part 4a, the locking mechanism 13 automatically locks the trigger member 4 so that the trigger member 4 is held in the stored position against the biasing force of the biasing member 12 even after the external force is removed. The locked state by the locking mechanism 13 is released by operating the lock release button 7. When the locked state is released, the trigger member 4 and the slide member 3, which moves integrally with the trigger member 4, move to the standby position by the biasing force of the biasing member 12. Note that such a locking mechanism 13 is a known technique, and therefore a detailed description thereof will be omitted here.

[0027] The slide member 3 and the trigger member 4 in the standby position can be moved from the standby position to the storage position by operating the operating portion 4a, i.e., by sliding the operating portion 4a toward the trapezoidal portion 22 against the biasing force of the biasing member 12.

[0028] The battery 14 is a rechargeable secondary battery that is housed inside the trapezoidal portion 22. The battery 14 and the charging port 6 are connected to each other so that the battery 14 can be charged via the charging port 6.

[0029] The heating circuit 15 is configured to heat the main body side plate 23 and the slide side plate 33 by energizing the main body side plate 23 and the slide side plate 33 using power stored in the battery 14. The heating circuit 15 is configured not only to control the energization on and off according to the power / temperature setting button 5, but also to change the heating temperature by changing the amount of energization. In addition, in Fig. 2 and Fig. 4, in order to make the drawings easier to see, the wiring between the battery 14 and the charging port 6, and the wiring between the heating circuit 15 and the power / temperature setting button 5, the battery 14, the main body side plate 23, and the slide side plate 33 are not shown.

[0030] [2. How to use] When the hair iron 1 is carried, as shown in Figures 2 and 4, the trigger member 4 is locked in the trigger storage position by the locking mechanism 13, i.e., the slide member 3 and the trigger member 4 are in the storage position.

[0031] When using the hair iron 1, the user first operates the lock release button 7 to release the locked state set by the lock mechanism 13. When the locked state by the locking mechanism 13 is released, the slide member 3 and the trigger member 4 move to the standby position by the biasing force of the biasing member 12, as shown in Figures 1 and 3. As a result, the main body side plate 23 and the slide side plate 33 are placed facing each other with a gap therebetween.

[0032] Next, when the user operates the power / temperature setting button 5 to turn the power on (that is, to set a low or high temperature), the main body side plate 23 and the slide side plate 33 are heated.

[0033] Next, place the hair to be worked on between the main body side plate 23 and the slide side plate 33 (hereinafter, between the plates), operate the trigger member 4 with your fingers to narrow the gap between the plates so that the hair is sandwiched between them, and then operate the hair iron 1 appropriately. This operation arranges the hair into a straight or wavy state, etc.

[0034] When the user has finished using the hair iron 1 and is putting it away, he or she first operates the power / temperature setting button 5 to turn the power off. Next, the operator operates the trigger member 4 to move the slide member 3 and the trigger member 4 to the stored position. Then, the lock mechanism 13 is actuated to enter a locked state, and the slide member 3 and the trigger member 4 are held in the stored position as shown in Figs. 3 and 4.

[0035] [3. Effects] According to the embodiment described above in detail, the following effects are achieved. (a) The hair iron 1 is formed in a card shape and has a structure that allows hair to be sandwiched between the main body side plate 23 and the slide side plate 33 by linearly sliding the slide member 3. Therefore, according to the hair iron 1, it is possible to provide a hair iron 1 that is smaller, lighter, and thinner than a conventional device having two arms connected by a hinge, and is easy to carry.

[0036] [4. Other embodiments] Although the embodiments of the present disclosure have been described above, the present disclosure is not limited to the above-described embodiments and can be implemented in various modified forms.

[0037] (4a) In the above embodiment, both the body side plate 23 and the slide side plate 33 are configured to be heated by passing electricity through them, but this is not limited to the above. For example, only one of the body side plate 23 and the slide side plate 33 may be heated. In this case, the plate on the side that is not heated may be made of a material with high heat retention.

[0038] (4b) In the above embodiment, the power / temperature setting button 5 and the lock mechanism 13 are configured to operate independently, but this is not limited thereto. For example, the power / temperature setting button 5 may be configured to forcibly turn off the power in conjunction with the lock mechanism 13 when the lock mechanism 13 is in the locked state. In this case, it is possible to prevent forgetting to turn off the power. Also, when the lock mechanism 13 is in the locked state, the operation of the power / temperature setting button 5 may be disabled. In other words, it may be configured so that the operation to turn on the power is possible only when the lock is released. In this case, it is possible to prevent the occurrence of a malfunction in which the power is unintentionally turned on when the hair iron 1 is not being used, such as when it is being carried around.

[0039] (4c) In the hair iron 1 shown in the above-described embodiment, the support 32 constituting the slide member 3 is provided only at one end in the Y-axis direction of the holding plate 31. In contrast, as in the hair iron 1a shown in Fig. 5, the support 32a, 32b may be provided at each end in the Y-axis direction of the holding plate 31. In such a hair iron 1a, even if the support 32a, 32b are made thinner than the support 32 in the above-described embodiment, the strength required for the slide member 3 can be maintained, and therefore the weight can be reduced.

[0040] (4d) Multiple functions possessed by one component in the above embodiments may be realized by multiple components, or one function possessed by one component may be realized by multiple components. Also, multiple functions possessed by multiple components may be realized by one component, or one function realized by multiple components may be realized by one component. Also, part of the configuration of the above embodiments may be omitted. Also, at least part of the configuration of the above embodiments may be added to or substituted for the configuration of another of the above embodiments.
