The massage device 1 of this embodiment includes a torsion unit 10, and by injecting air into the torsion unit 10, the torsion unit 10 can twist, press, and pull the skin, cellulite decomposition and It can give an excellent massage effect.

After the torsion unit 10 is manufactured in an unfolded state as shown in FIG. 2 , both ends of the plate 14 are connected to form a cylindrical shape. Accordingly, the user body insertion space 2 shown in FIG. 1 may be formed inside the torsion unit 10 . The user's body (eg, forearm, wrist, thigh, calf) may be inserted into the user body insertion space 2 , and after the user's body is inserted into the user body insertion space 2 , the torsion unit 10 As the torsion is generated by the expansion, a massage effect by twisting, pressing, and pulling can be given to the body inserted into the user's body insertion space 2 .

The torsion unit 10 may include a portion that can be differently deformed as air is introduced into the torsion channel 13 .

For example, the torsion unit 10 may be formed of a plurality of materials having different elastic moduli.

Specifically, the torsion unit 10 is provided with a material having a first elastic modulus, and includes a plurality of chambers 12 forming a plurality of torsion channels 13 ; And connecting the plurality of chambers 12, but may include a plate 14 provided with a material having a second elastic modulus greater than the first elastic modulus.

Here, one torsion channel 13 may be formed by one chamber 12 (the number of chambers 12 and the number of torsion channels 13 are provided to be the same), and the torsion channel 13 may be air can be understood as an empty space into which

The chamber 12 includes a plurality of side walls 121 extending upwardly from the plate 14; and an upper wall 122 connecting the plurality of side walls 121 .

When the chamber 12 is provided in a rectangular parallelepiped shape, the side wall 121 may form the side surfaces (four sides) of the torsion channel 13 , and the upper wall 122 may form the upper surface of the torsion channel 13 . may be formed, and the plate 14 may form the lower surface of the torsion channel 13 .

In addition, the torsion unit 10 may be provided with a plurality of protrusions (not shown). Specifically, the upper wall 122 of the torsion unit 10 may be provided with a plurality of projections (shown).

In addition, the torsion unit 10 or the bending unit 40 to be described later may be provided with a sensor 17 capable of measuring a skin condition. Specifically, on the upper wall 122 of the torsion unit 10 or the upper wall of the bending unit 40 that can come in contact with the skin, there is a sensor 17 that can measure the skin condition (eg, skin elasticity or muscle mass). ) may be provided. In this case, the degree to which the skin is twisted or the degree to which the skin is pressed may be measured through the sensor 17 , and the torsion unit 10 may be expanded and twisted in an automatic mode to be described later according to the skin condition.

In addition, the plurality of torsion channels 13 may be formed to communicate with each other. For example, the plate 14 may be provided with a passage 19 through which the plurality of torsion channels 13 communicate with each other. As a result, the air introduced from the first compressor 15 is injected into the torsion channel 13 that is inside the chamber 12, so that the plurality of chambers 12 and the plurality of torsion channels 13 can be expanded. have

In addition, the side wall 121 and the upper wall 122 are provided with the same material, and the side wall 121 may be provided to be thicker than the upper wall 122 . In this case, as air is introduced into the torsion channel 13 , a large deformation may occur in the order of the upper wall 122 , the side wall 121 , and the plate 14 . That is, the greatest deformation of the upper wall 122 in direct contact with the user's skin can occur, thereby maximizing the skin massage effect.

The plate 14 may provide the torsion unit 10 as a whole in one configuration by connecting the plurality of chambers 12 .

The chamber 12 may be provided of an elastomer having a first modulus of elasticity, and the plate 14 may be provided of an elastomer having a second modulus of elasticity greater than the first modulus of elasticity.

That is, it is understood that the volume of the torsion channel 13 in the expanded state (FIG. 3(b)) of the torsion unit 10 is larger than the volume of the torsional channel 13 in the state before expansion (FIG. 3(a)). can be

The torsion unit 10 including the above-described expanding torsion channel 12 may be understood as a deformable soft actuator, and the desired elastic modulus (or bending stiffness) between the chamber 12 and the plate 14 is varied. By designing the curvature, it is possible to implement a deformation suitable for the massage device.

In addition, air is introduced into the torsion channel 13 of the chamber 12 from the first compressor 15 to be described later, so that the torsion unit 10 may expand.

The state before the expansion of the torsion unit 10 shown in FIG. 3 (a) can be understood as the state before the first compressor 15 is operated, and the torsion unit 10 shown in FIG. The expanded state may be understood as a state in which air is injected into the torsion channel 13 after the first compressor 15 is operated.

In addition, the torsion channel 13 provided in the torsion unit 10 may be formed to have a preset angle θ.

Specifically, the preset angle θ of the torsion unit 10 may have a range of 15° to 75°, preferably 30° to 60°, and more preferably 45°.

Here, the preset angle θ is when the torsion unit 10 is unfolded (see FIG. 4 ), the direction (x-axis) in which the torsion unit 10 is unfolded and the torsion channel 13 formed inside the chamber 12 is It may be understood as an angle formed by the extending direction. In this embodiment, the angle of the chamber 12 and the angle of the torsion channel 13, which is an empty space formed inside the chamber 12, may be understood to be the same.

As such, the chamber 12 of the torsion unit 10 and the torsion channel 13 formed thereby are formed to have a preset angle θ, so that when the torsion unit 10 is expanded, the torsion unit 10 is can be twisted Thereby, the massage device 1 can give the effect of twisting, pressing, and pulling the user's skin.

7 is an experimental photograph showing torsion due to expansion of the torsion unit 10 when the torsion channel 13 of the torsion unit 10 is formed at 45°, and air is injected in a state in which the torsion unit 10 is unfolded. to be. By forming the torsion channel 13 to have a preset angle θ in this way, it can be seen that the torsion of the torsion unit 10 occurs.

The first compliance layer 20 may be disposed between the torsion unit 10 and the exoskeleton layer 30 , and may function to freely allow movement (torsion due to expansion) of the torsion unit 10 .

Specifically, the first compliance layer 20 may be provided of a material having a smaller elastic modulus than the torsion unit 10 and the exoskeleton layer 30 . For example, the first compliance layer 20 may be provided as an elastomer having a third elastic modulus, and the third elastic modulus may be provided to be smaller than the above-described first elastic modulus and second elastic modulus.

The first compliance layer 20 may be selectively provided, and when the first compliance layer 20 is not provided, the massage device 1 may be disposed in the torsion unit 10 and the exoskeleton layer 30 in that order. And, when the first compliance layer 20 is provided, the massage device 1 may be provided in the order of the torsion unit 10 , the first compliance layer 20 , and the exoskeleton layer 30 .

In this case, the user can easily insert the body into the user body insertion space (2).

However, this is merely exemplary, and the second part 34 may include a strap provided. For example, one side of the second portion 34 may be provided selectively detachably from the first portion 32 . In this case, one side of the second part 34 is separated from the first part 32 , the user's body is inserted into the user's body insertion space 2 , and then the separated second part 34 is placed back into the first part. By connecting to the part 32 , it is possible to firmly fix the user's body to the massage device 1 .

In addition, the massage device 1 may further include a bending unit 40 including a bending channel (not shown) into which air may be injected between the plurality of chambers 12 .

Specifically, the second compliance layer 50 may be provided of a material having a smaller elastic modulus than that of the torsion unit 10 . For example, the second compliance layer 50 may be provided as an elastomer having a fourth elastic modulus, and may be provided to be smaller than the above-described first elastic modulus and second elastic modulus.

By providing such a second compliance layer 50, when the bending unit 40 expands and fixes the user's body, the second compliance layer 50 may be deformed larger than that of the torsion unit 10, The torsion unit 10 may be unaffected or less affected.
