Embodiments of the present invention will be described below based on examples shown in the drawings. Note that the embodiments are not limited to the following.
FIG. 1 is a view showing the front side of a cosmetic band (1) according to the present invention, and FIG. 2 is a view showing the back side of the same.

In this embodiment, the cosmetic band (1) is made of a flexible material mainly made of silicone on the front and back surfaces, and other materials are combined in each part as will be described later. The use of silicone material makes it easier to shape and wind, while also being gentle on the skin and contributing to comfortable wearability.
However, in the present invention, these materials are arbitrary, and for example, the entire body can be formed of other resins or cloth.

The beauty band (1) includes a band-like body (10) constituting the main body, leaf springs (11) (11) installed inside the band-like body (10), and electrodes that are in contact with the user's skin on the back side. (12) (12) and a power supply unit (13) for energizing the leaf springs (11) (11).

The band-like body (10) includes, in order from the left in the figure, an elastic winding part (100) housing a leaf spring (11), a connecting part (101), a power supply attachment part (102), and a flexible part (103). , and each part of the magnetic attachment part (104).

The elastic winding part (100) is equipped with two leaf springs (11) (11) arranged vertically in parallel, which is one of the features of the present invention, and extends over approximately half the length in the longitudinal direction. ing. Specifically, it is about 30 cm, and the length when wound is about 6 cm to 10 cm to fit the length. This length is mainly intended for the beauty band of this embodiment to be wrapped around the upper arm, and it goes without saying that the length can be set as appropriate depending on the target area to be worn.

Electrodes (12) (12) are provided on the back surface of the elastic winding section (100). The electrode (12) is made of conductive silicon, and current is applied to the skin surface between the upper and lower electrodes (12) (12). In the present invention, the electrode (12) is in electrical contact with a leaf spring (11) of electrically conductive material.

By forming the electrodes from conductive silicon, they can have an appearance that is integrated with the band-like body (10), and have excellent waterproof properties, making it easy to wash with water or use gel. Although conductive silicone is used in this embodiment, any conductive rubber that is similarly resistant to water may be used. The conductive rubber is known to be a mixture of various rubber raw materials such as natural rubber and synthetic rubber with conductive carbon black or metal powder, and these can be used as appropriate.

As described above, in the present invention, unlike conventional products, conductive rubber is used for the electrodes, but a drawback of conductive rubber is that the conductivity is not necessarily high. Therefore, compared to the case where a conductive thread is used, there is a problem in that if only one end is energized, sufficient power cannot be supplied to the entire electrode.
To solve this problem, the present invention applies a constant amount of electricity to the skin within the range of the leaf spring by directly contacting the leaf spring (11) made of a conductive material with the electrode (12) made of conductive rubber. As a result, sufficient current can be achieved.

Note that the material of the band-like body (10) and the material of the electrodes are also arbitrary depending on the design. For example, it may be formed of a conductive cloth made of conductive thread, and the conductive cloth may be sewn to the band-like body (10). Even in this case, the structure in which the leaf spring and the conductive cloth are in direct contact with each other makes it difficult to cause poor contact and contributes to a sufficient power supply.

Although it is easiest to have the leaf spring (11) and the electrode (12) in direct contact as described above, a separate electric wire or contact may be provided as a conductive path for electrical connection. In the present invention, it is most important to use the leaf spring (11) as a current conduction path from the power supply section (13), and the configuration of the conduction path between the leaf spring (11) and the electrode (12) is arbitrary.
When using electric wires or contacts, it is preferable that the current be applied to a plurality of points along the entire length of the leaf spring (11). By making electrical contact at least at both ends and the center of the leaf spring, sufficient power can be supplied even with conductive rubber as described above.

The connecting portion (101) continuing to the left of the elastic winding portion (100) is formed with recesses (101a) (101a) that become smaller in the width direction. By providing the recessed portion (101a), it is formed to be more easily bent than the elastic winding portions (100) and the power supply mounting portion (102) on both sides. As a result, by swinging the elastic winding part (100) by holding the vicinity of the power supply attachment part (102), the peripheral speed of the elastic winding part (100) can be increased and it can be wrapped around the target area with force. can.

Furthermore, the recessed portion (101a) also has the effect of making it easier to surround the power supply mounting portion (102) with the palm of the hand and place the finger on it. The elastic winding part (100) can be prevented from slipping when it is swung by the fingers, and can be wrapped around the target region with sufficient force.

When using conductive rubber or silicone material for the band-like body (10) as in this example, the overall shape is easier to maintain than cloth, but on the other hand, it may be difficult for the electrodes to come into close contact with the skin. . According to the present invention, adhesion to the skin surface can be improved by using the leaf spring (11). The configuration of the present invention in which an elastically wound leaf spring is combined with a silicon material is particularly suitable.

A power supply section (13) is integrally attached to the power supply mounting section (102). By making it an integrated type, you can improve the seamless appearance, ease of maintenance, and waterproofness. Various buttons (130), (131), and (132) of the power supply section (13) are arranged on the surface and can be operated.

The power supply section (13) has a built-in rechargeable battery, and an internal control circuit enables it to output the pulse current necessary for the EMS.

In this embodiment, the + button (130) and the - button (131) can be used to control the strength of the EMS and heater, and the power button (132) can be used to turn on and off the power.
The operating time of the EMS is, for example, about 10 minutes, and the power supply section (13) can be provided with a timer to end the operation in a predetermined time.

Further, the power supply unit (13) may be provided with a function to measure the output current, and automatically stop when the output current exceeds a predetermined value. In the present invention, elastic force acts in the winding direction, so if the user feels pain, it may be difficult to remove it, so such a stop function can also prevent energization that would cause pain.

Note that the present invention is not limited to making the power supply unit (13) integral, but may be detachable.

The flexible portion (103) has a vertical groove (103a) and an opening (103b) to make it easier to wind than the connecting portion (101). During use, the magnetically attached part (104) at the right end is magnetically attached and fixed to the elastically wound part (100) by wrapping it around the outer periphery of the elastically wound part (100).

That is, the magnetic attachment part (104) is equipped with a magnetic material such as a magnet, so that it can be magnetically attached to the leaf spring (11). By using the leaf spring (11), the beauty band can be fixed at any location, and there is no need to provide a separate member to the receiving part that is the magnetically attached part of the magnetically attached part (104). It also contributes to reducing scores and improving appearance.

Note that, depending on the length of the beauty band and the material of the band-like body, the receiving portion does not necessarily have to serve as a leaf spring in the present invention. A configuration may also be adopted in which a magnetically attractable member is separately provided on the surface side and is magnetically attached to the magnetically attached portion (104).
The structure is not limited to a structure in which the structure is fixed by magnetic attraction, but may be a structure in which it is attached by a hook-and-loop fastener.
Further, the end portion may not be fixed in the first place, but may be wound and fixed only by the elasticity of the elastic winding portion (100).

Two or more cosmetic bands (1) of the present invention can also be used. For example, when used on the abdomen, the first magnetically attached part (104) is magnetically attached to the end of the second elastic winding part (100), and the second magnetically attached part (104) and the first By magnetically attaching the elastic winding part (100) to any part, the beauty band (1) can be attached to parts of various thicknesses and beauty treatments can be performed.

Here, the leaf spring (11) will be explained using FIGS. 3 and 4.
The leaf spring (11) used in the present invention is a spiral spring having elasticity in the winding direction, and at the same time has an arcuate cross section. As shown in FIG. 3(a), during stretching, the tension of the curved surface counteracts the force in the direction of f1, so that the stretched state is maintained by overcoming the elastic force (force of f2) that attempts to wind the film.

However, when the force f1 becomes even larger and reaches the point where the arc-shaped cross section is stretched into a straight line, the tension on the curved surface is released, and the elastic force f2 suddenly causes the coil to become wound as shown in FIG. 3(b). Such leaf springs are well known and are used, for example, in wristwatches (slap-on watches) that can be easily worn around the wrist.

In the present invention, a leaf spring (11) is applied to the beauty band (1), and the arcuate outer peripheral surface side in FIG. 3 is arranged on the back surface side. When the user grasps the power supply attachment part (102) and applies the elastic winding part (100) to the upper arm, etc., a strong force in the direction f1 is applied, and the elastic force (f2) of the winding allows the user to easily target the target area. It can be wrapped around.

The effects of the present invention using such a leaf spring (11) can be summarized as follows. That is, since a leaf spring is used that has elasticity in the direction in which it is intended to be wound, but restricts its winding when stretched flat, the beauty band (1) can be easily attached and detached with one touch even with one hand. can.

The plate spring (11) may be formed of a conductive material like a general plate spring (11), and the plate spring (11) can be used as a current-carrying path from the power supply section (13) to the electrode (12). There is a structural requirement that the power supply section (13) and the electrode (12) be installed at a certain distance from each other, but since they are frequently wound and stretched, it was necessary to take measures against wire breakage.
According to the present invention, it is possible to use a leaf spring (11) with no concerns about its strength, so it is possible to provide a current conduction path that is easy to manufacture and has excellent durability.
Furthermore, by using a leaf spring (11) having a wide surface, even a large current can be passed without any problem.

Furthermore, the plate spring (11) may be formed of a magnetic metal like a general plate spring (11), and the plate spring (11) can be used as a receiving part to which a magnet or the like at the end is magnetically attached. As a result, by simply providing a magnet on one side, it is possible to provide a fixing function that can be easily attached to and detached from any part.
Thus, it can be said that the application of the leaf spring (11) to the beauty band (1) has many effects synergistically.

In this embodiment, a heater section (14) is installed between the leaf springs (11) of the elastic winding section (100). By supplying power from the power source section (13), the heater section (14) exerts a thermal effect on the skin surface, contributing to enhancing the beauty effect.

By increasing the skin temperature with the heater part (14), metabolic efficiency can be improved and the effect of muscle training by EMS can be enhanced. In addition, by pre-warming the muscles, it is possible to reduce the burden.
Two leaf springs (11) (11) may also be used to supply power to the heater section (14).

FIG. 4 is an explanatory diagram showing the connection state between the leaf spring and the power supply unit. As shown in the figure, the upper electric wire (133), upper leaf spring (11), lower leaf spring (11), and lower electric wire (133) are electrically connected and energized from the power supply unit (13) in this order. do.
In addition, in the present invention, the leaf spring (11) may be used at either pole, and the counter electrode may be connected to the power supply section (13) using another current-carrying path.

FIG. 5 is an explanatory diagram of another embodiment showing a connection state between a leaf spring and a power supply section.
One leaf spring (11') is electrically divided into two parts in at least one of the width directions, and the upper part (111) and the lower part (112) form a pair of poles with the insulating part (110) in between. are doing. The upper part (111) and the lower part (112) are electrically connected to the power supply section (13) through electric wires (133), respectively.

Alternatively, one leaf spring may be divided in the thickness direction. For example, a configuration may be adopted in which the front surface and the back surface form a pair of poles with an insulating layer in between.
Furthermore, it may be divided in the longitudinal direction and used as a current supply path. It may be divided into a left half and a right half in the figure, and an insulating section may be provided in the middle.

As described above, the beauty band according to the present invention can be tightened just the right amount by using the leaf spring (11) as a current-carrying path, and can also be used to connect the leaf spring (11) to the current-carrying electrode. By using a path, a constant amount of electricity can be applied to the skin surface within the range of the leaf spring, even if the electrode is covered with a non-conductive current-carrying material.
In particular, since it becomes possible to use conductive silicon or the like for the electrodes, it is strong against wet objects, and dirt can be wiped off, making it possible to use it cleanly.
