[0088] A massage device (100) according to one embodiment of the present disclosure may include a sensor unit (1800). In this case, the sensor unit (1800) may include at least one sensor. For example, the sensor unit (1800) may include a pressure sensor, an infrared sensor, an LED sensor, a photo sensor, a Hall sensor, a capacitive sensor, etc., but is not limited thereto.

[0089] The sensor unit (1800) can be used to acquire various information. For example, the sensor unit (1800) can be used to recognize a user. That is, it can acquire information regarding whether the user is seated, the user's body shape, and whether there are any physical abnormalities in the user. As another example, the sensor unit (1800) can be used to acquire biometric information. That is, it can acquire fingerprint information, facial information, voice information, iris information, weight information, electrocardiogram information, body composition information, etc., but is not limited thereto and may include various biometric information.

[0090] According to another embodiment of the present disclosure, a massage device (100) can detect a contact area and / or contact location with a user through a sensor unit (1800). Additionally, the massage device (100) can obtain information on the user's shoulder position through the sensor unit (1800). Additionally, the massage device (100) can provide a customized massage based on the obtained information. For example, when the massage device (100) provides a shoulder massage, the massage device (100) can recognize the user's shoulder position based on the information obtained through the sensor unit (1800) and provide a shoulder massage to the user according to the recognition result.

[0091] The leg massager (2000) may be configured to massage the user's leg. A leg receiving space in which the user's leg is received may be formed in the leg massager (2000).

[0092] The leg massage unit (2000) may include at least one of an air cell (not shown), a calf massage module (not shown), and a foot massage unit (not shown).

[0093] The air cell (not shown) may be configured to fix at least a part of the user's body. The air cell included in the leg massage unit (2000) may be configured to fix at least a part of the user's body by receiving air from a separately provided air supply unit and expanding.

[0094] A calf massage module (not shown) may be configured to massage the calf portion of the leg of a user. In this case, the calf massage module may include, but is not limited to, a ball massage unit or a roller massage unit as described above.

[0095] A foot massage unit (not shown) may be configured to massage a user's foot. The foot massage unit may include a foot massage module for massaging a user's foot. In this case, the foot massage module may include a ball massage unit or a roller massage unit, but is not limited thereto.

[0096] Hereinafter, a massage device including an individually driven leg massager according to one embodiment of the present invention will be described in detail with reference to the drawings.

[0097] FIG. 4 is a drawing to explain that the leg massage part (2000) of FIG. 1 rotates individually.

[0098] Referring to FIG. 4, a massage device (100) according to one embodiment of the present invention may include a body massage part (1000) that accommodates at least a part of a user's body and massages the user's body, and a leg massage part (2000) that is disposed at one end of the body massage part (1000) and massages the user's leg.

[0099] The leg massage unit (2000) may be provided to correspond to both legs of the user. For example, the leg massage unit (2000) may include a first leg massage unit (2000a) corresponding to one leg of the user and a second leg massage unit (2000b) corresponding to the other leg of the user. In this case, the first leg massage unit (2000a) may correspond to the right leg of the user, and the second leg massage unit (2000b) may correspond to the left leg of the user. However, this distinction is made for convenience, and the first leg massage unit (2000a) may correspond to the left leg of the user, and the second leg massage unit (2000b) may correspond to the right leg of the user.

[0100] The first leg massage unit (2000a) and the second leg massage unit (2000b) can be controlled individually, and specifically, the first leg massage unit (2000a) and the second leg massage unit (2000b) can be rotated individually. That is, the first leg massage unit (2000a) and the second leg massage unit (2000b) can move independently of each other, and accordingly, the user can receive different massages on both legs or receive massages alternately on both legs as needed. In addition, the user may receive stretching or massage through rotation on both legs, and in this case, the massage device (100) can rotate both of the user's legs simultaneously or individually.

[0101] Figure 5 is a diagram illustrating the principle of rotation of a conventional leg massager.

[0102] Referring to FIG. 5, a conventional massage device includes a leg angle actuator (240) for rotating a leg massage part (200).

[0103] The leg angle actuator (240) can be placed inside the body massage unit (1000) and, for example, connected to the main frame (1100).

[0104] The leg angle actuator (240) can be driven to extend in one direction, thereby rotating the leg massage unit (200). The leg angle actuator (240) includes a link member (230) that contacts the leg massage unit (200) at one end and transmits power to the leg massage unit (200). At this time, the link member (230) includes a wheel at the part that contacts the leg massage unit (200).

[0105] The leg massage unit (200) includes a leg frame (210) positioned at the rear and a leg support unit (220) connected to the leg frame (210) and providing a path for the wheel of a link member (230) to move.

[0106] Accordingly, as the leg angle actuator (240) is extended, the wheel of the link member (230) can roll along the leg support (220), and accordingly, the leg massager (200) connected to the leg support (220) can rotate.

[0107] As described above, the conventional leg massage unit (200) adopted a structure in which a wheel positioned on one side of the link member (230) moves along the leg support member (220) by driving the leg angle actuator (240) to rotate. In this case, for the leg massage unit (200) to rotate to an angle greater than a predetermined range, the extension range of the leg angle actuator (240) must be wide, thus requiring a relatively large leg angle actuator (240). Therefore, due to the characteristics of the massage device used indoors, there are difficulties in designing the placement of the actuator. Furthermore, in the case of the aforementioned type, a problem may arise in which the leg massage unit (200) does not rotate relatively smoothly.

[0108] FIG. 6 is a drawing for explaining a driving module of a leg massage unit (2000) according to one embodiment of the present invention, and FIG. 7 is an enlarged drawing of part A of FIG. 6.

[0109] Referring to FIGS. 6 and 7, a massage device according to one embodiment of the present invention may include a main frame (1100) forming the skeleton of the massage device, a body massage unit (1000) for massaging a user's body, a leg massage unit (2000) including a first leg massage unit (2000a) corresponding to one leg of the user and a second leg massage unit (2000b) corresponding to the other leg of the user, and a driving module disposed in the body massage unit (1000) for rotating the leg massage unit (2000).

[0110] At this time, the main frame, body massage unit, and leg massage unit may selectively apply the contents regarding the main frame (1100), body massage unit (1000), and leg massage unit (2000) described above, or modify and apply them as needed.

[0111] The first leg massage unit (2000a) and the second leg massage unit (2000b) can be rotated individually, and to this end, the driving module may include a first driving module that rotates the first leg massage unit (2000a) and a second driving module that rotates the second leg massage unit (2000b).

[0112] In the following description of the operation of the leg massage unit (2000) according to the present embodiment, the term "leg massage unit (2000)" refers to the first leg massage unit (2000a) and the second leg massage unit (2000b), and the statement that the leg massage unit (2000) may include a certain configuration may mean that the first leg massage unit (2000a) and the second leg massage unit (2000b) may each include such configuration.

[0113] In addition, in describing the driving module according to the present embodiment, the term "driving module" refers to the first driving module and the second driving module, and the statement that the driving module may include a certain configuration may mean that the first driving module and the second driving module may each include such configuration.

[0114] The driving module according to the present embodiment may be a driving module according to the motor type.

[0115] In one embodiment, the drive module may include a leg angle motor (2110), a power transmission member (2120), and a pulley (2130).

[0116] The leg angle motor (2110) may be a means for generating rotational force to rotate the leg massage unit (2000) by receiving power.

[0117] The leg angle motor (2110) can be placed in the body massage unit (1000) and, specifically, connected to the main frame (1100).

[0118] The leg massage unit (2000) may include an axis member forming a rotation axis for rotation. The axis member may be positioned on one side of the leg massage unit (2000), for example, at a position adjacent to the user's knee. Accordingly, the leg massage unit (2000) can rotate around the axis member by receiving force from the leg angle motor (2110).

[0119] In one embodiment, the leg angle motor (2110) may be positioned below the shaft member, specifically below the leg connecting frame. Accordingly, the leg angle motor (2110) may be positioned relatively close to the leg massage unit (2000), and a space for the leg angle motor (2110) to be positioned within the body massage unit (1000) may be secured.

[0120] The power transmission member (2120) may be a means of transmitting rotational force generated from the leg angle motor (2110) to the leg massage unit (2000). For example, the leg angle motor (2110) may include a gear that rotates by receiving power, and the power transmission member (2120) may come into contact with the gear and rotate together with it to correspond to the rotation of the gear.

[0121] In one embodiment, the power transmission member (2120) may be a timing belt. Accordingly, the timing belt may include teeth that mesh with the gears and thus can easily transmit the rotational force generated from the leg angle motor (2110).

[0122] As an optional embodiment, the power transmission member (2120) may be made of rubber. As another example, the power transmission member (2120) may be made of metal, and may be, for example, a chain containing metal.

[0123] The pulley (2130) may be a means of transmitting rotational force received from the power transmission member (2120) to the leg massage member (2000).

[0124] The pulley (2130) can be installed to be coupled with the shaft member of the leg massage unit (2000), and, for example, can be coupled with the shaft member to rotate together.

[0125] Accordingly, the pulley (2130) can rotate together with the shaft member by the rotational force transmitted from the power transmission member (2120), and accordingly, the leg massage member (2000) can rotate.

[0126] The power transmission member (2120) may be positioned to surround at least a portion of the gear and pulley (2130) of the leg angle motor (2110). Thus, even if the leg angle motor (2110) and the pulley (2130) are separated by a predetermined distance, the rotational force generated from the leg angle motor (2110) can be transmitted to the pulley (2130).

[0127] As an optional embodiment, the diameter of the gear of the leg angle motor (2110) may be smaller than the diameter of the pulley (2130). Therefore, when the gear rotates relatively a lot, the pulley (2130) can rotate relatively little, so that the rotation of the leg massage part (2000) can be done slowly.

[0128] That is, even when the leg angle motor (2110) rotates rapidly, the pulley (2130) can rotate slowly, and accordingly, the leg massage unit (2000) can also rotate slowly, thereby ensuring the safety of the user of the massage device. In addition, the leg massage unit (2000) can rotate smoothly, providing a comfortable user experience.

[0129] FIG. 8 is a diagram for explaining the principle of rotation of the leg massage part (2000) of FIG. 6.

[0130] Referring to FIG. 8, the power transmission member (2120) can rotate together by driving the leg angle motor (2110). For example, the power transmission member (2120) can rotate together in a direction corresponding to the rotation direction of a gear placed at one end of the leg angle motor (2110).

[0131] Specifically, when the gear of the leg angle motor (2110) rotates clockwise with respect to FIG. 8, the power transmission member (2120) can rotate clockwise to correspond to the rotation direction of the leg angle motor (2110), and accordingly, the pulley (2130) connected to the power transmission member (2120) can also rotate clockwise to correspond to this. Therefore, the leg massage unit (2000) can also rotate clockwise to correspond to the rotation direction of the pulley (2130), and consequently, the leg massage unit (2000) can be lifted.

[0132] Conversely, when the gear of the leg angle motor (2110) rotates counterclockwise with respect to FIG. 8, the power transmission member (2120) can rotate counterclockwise to correspond to the rotation direction of the leg angle motor (2110), and accordingly, the pulley (2130) connected to the power transmission member (2120) can also rotate counterclockwise to correspond to this. Therefore, the leg massage unit (2000) can also rotate counterclockwise to correspond to the rotation direction of the pulley (2130), and eventually the leg massage unit (2000) comes down.

[0133] FIG. 9 is a drawing for explaining a driving module of a leg massage unit (2000) according to another embodiment of the present invention, FIG. 10 is an enlarged drawing of part B of FIG. 9, and FIG. 11 is a schematic drawing of the driving module of FIG. 9.

[0134] Referring to FIGS. 9 to 11, a massage device according to another embodiment of the present invention may include a main frame (1100) forming the skeleton of the massage device, a body massage unit (1000) for massaging a user's body, a leg massage unit (2000) including a first leg massage unit (2000a) corresponding to one leg of the user and a second leg massage unit (2000b) corresponding to the other leg of the user, and a driving module disposed in the body massage unit (1000) for rotating the leg massage unit (2000).

[0135] At this time, the main frame, body massage unit, and leg massage unit may selectively apply the contents regarding the main frame (1100), body massage unit (1000), and leg massage unit (2000) described above, or modify and apply them as needed.

[0136] The first leg massage unit (2000a) and the second leg massage unit (2000b) can be rotated individually, and to this end, the driving module may include a first driving module that rotates the first leg massage unit (2000a) and a second driving module that rotates the second leg massage unit (2000b).

[0137] In the following description of the operation of the leg massage unit (2000) according to the present embodiment, the term "leg massage unit (2000)" refers to the first leg massage unit (2000a) and the second leg massage unit (2000b), and the statement that the leg massage unit (2000) may include a certain configuration may mean that the first leg massage unit (2000a) and the second leg massage unit (2000b) may each include such configuration.

[0138] In addition, in describing the driving module according to the present embodiment, the term "driving module" refers to the first driving module and the second driving module, and the statement that the driving module may include a certain configuration may mean that the first driving module and the second driving module may each include such configuration.

[0139] The driving module according to the present embodiment may be a driving module of the type using a motor and a screw.

[0140] In one embodiment, the drive module may include a leg angle motor (2210), a power transmission member (2220), a lead screw (2230), a screw pulley housing (2240), and a wheel (2250).

[0141] The leg angle motor (2210) may be a means for generating rotational force to rotate the leg massage unit (2000) by receiving power.

[0142] The leg angle motor (2210) can be placed in the body massage unit (1000) and, for example, connected to the main frame (1100). At this time, in order for the screw pulley housing (2240) to move up and down by the leg angle motor (2210) as described below, a space must be secured within the body massage unit (1000) for the screw pulley housing (2240) to move up and down, and for this purpose, it is preferable for the leg angle motor (2210) to be placed relatively lower.

[0143] Accordingly, for this purpose, the main frame (1100) may further include a drive frame to which a drive module is connected. Specifically, the drive frame may be installed to extend from the main frame (1100) toward the bottom surface. A support having a width may be disposed at one end of the drive frame, and a leg angle motor (2210), a lead screw (2230), and a screw pulley housing (2240) may be connected to the support.

[0144] The power transmission member (2220) may be a means of transmitting rotational force generated from the leg angle motor (2210) to the lead screw (2230). For example, the leg angle motor (2210) may include a gear that rotates by receiving power, and the power transmission member (2220) may come into contact with the gear and rotate together with it to correspond to the rotation of the gear.

[0145] In one embodiment, the power transmission member (2220) may be a timing belt. Accordingly, the timing belt may include teeth that mesh with the gears and thus can easily transmit the rotational force generated from the leg angle motor (2210).

[0146] As an optional embodiment, the power transmission member (2220) may be made of rubber. As another example, the power transmission member (2220) may be made of metal, and may be, for example, a chain containing metal.

[0147] The lead screw (2230) receives power from the power transmission member (2220) and rotates, and may be a means for moving the screw pulley housing (2240) up and down by the rotation.

[0148] In one embodiment, a rotating part may be disposed at one end of the lead screw (2230) to be in contact with a power transmission member (2220).

[0149] That is, the power transmission member (2220) is in contact with both the leg angle motor (2210) and the rotating part of the lead screw (2230), so that the rotation generated by the leg angle motor (2210) can be transmitted to the lead screw (2230).

[0150] As an optional embodiment, the diameter of the gear of the leg angle motor (2210) may be smaller than the diameter of the rotating part. Therefore, when the gear rotates relatively a lot, the rotating part can rotate relatively little, so the rotation of the leg massage part (2000) can be done slowly.

[0151] That is, even when the leg angle motor (2210) rotates rapidly, the lead screw (2230) can rotate slowly, and accordingly, the leg massage unit (2000) can also rotate slowly, thereby ensuring the safety of the user of the massage device. In addition, the leg massage unit (2000) can rotate smoothly, providing a comfortable user experience.

[0152] The screw pulley housing (2240) may be a means for rotating the leg massage unit (2000) while moving up and down along the lead screw (2230) by the rotation of the lead screw (2230). At this time, the screw pulley housing (2240) may include a through hole for inserting the lead screw (2230), and the lead screw (2230) may be positioned to penetrate the screw pulley housing (2240).

[0153] A spiral groove may be formed on the surface of the lead screw (2230), and a screw thread may be formed on the surface of the through hole formed in the screw pulley housing (2240) to mesh with the spiral groove formed in the lead screw (2230).

[0154] Accordingly, as the lead screw (2230) rotates, the screw pulley housing (2240) can move up and down by means of the screw threads that mesh with it.

[0155] Since the screw pulley housing (2240) moves up and down by the rotation of the lead screw (2230), the direction of movement of the screw pulley housing (2240) can be parallel to the longitudinal direction of the lead screw (2230).

[0156] As an optional embodiment, the drive frame may be formed to have a length parallel to the direction of movement of the screw pulley housing (2240). That is, the drive frame and the lead screw (2230) may be formed to extend parallel to each other. Additionally, a guide groove may be formed along the length of one side of the drive frame, and the screw pulley housing (2240) may include a protrusion that is inserted into the guide groove. Accordingly, when the screw pulley housing (2240) moves up and down, the protrusion can move along the guide groove. That is, the drive frame can guide the direction of movement of the screw pulley housing (2240).

[0157] The wheel (2250) may be a means for rolling along one side of the screw pulley housing (2240) and the leg massage part (2000).

[0158] In one embodiment, the leg massage unit (2000) may further include a leg support unit (2260) disposed on the back surface, and the wheel (2250) may move along the leg support unit (2260). Specifically, the leg support unit (2260) may be disposed on the back surface of the leg massage unit (2000) and formed to extend along the longitudinal direction of the leg massage unit (2000).

[0159] As the lead screw (2230) rotates, the screw pulley housing (2240) moves up and down, and the wheel (2250) can roll along the leg support (2260) to lift the leg massager (2000). That is, the leg support (2260) can provide a path for the wheel (2250) to move while rolling.

[0160] As an optional embodiment, the leg support (2260) may include a curved surface corresponding to the wheel (2250) so that the wheel (2250) does not deviate from the path while moving. For example, the support may include a curved surface concave inward so that the wheel (2250) can be seated thereon, and the wheel (2250) can move while rolling while seated on the concave curved surface.

[0161] In this way, the screw pulley housing (2240) does not directly lift the leg massage unit (2000) while moving up and down, but lifts it using the rotation of the wheel (2250), thereby allowing the leg massage unit (2000) to rotate smoothly and providing a comfortable user experience.

[0162] FIG. 12 is a diagram for explaining the principle of rotation of the leg massage part (2000) of FIG. 9.

[0163] Referring to FIG. 12, the screw pulley housing (2240) can move up and down by driving the leg angle motor (2210). For example, the direction of movement of the screw pulley housing (2240) may depend on the direction of rotation of the leg angle motor (2210).

[0164] At this time, the rotation direction of the leg angle motor (2210) and the movement direction of the screw pulley housing (2240) can be determined according to the direction of the spiral formed on the lead screw (2230). That is, if the direction of the spiral formed on the lead screw (2230) is formed in the opposite direction, the rotation direction of the leg angle motor (2210) and the movement direction of the screw pulley housing (2240) can be opposite to each other.

[0165] Specifically, when the leg angle motor (2210) rotates in a predetermined direction, the lead screw (2230) can rotate in a corresponding direction. Due to the rotation of the lead screw (2230), the screw pulley housing (2240) can move in a corresponding direction and, for example, can rise. Accordingly, the wheel (2250) positioned on one side of the screw pulley housing (2240) can move while rolling on the surface of the leg support (2260), and the leg massage part (2000) can be lifted.

[0166] Conversely, when the leg angle motor (2210) rotates in the opposite direction, the lead screw (2230) can also rotate in a corresponding direction. Due to the rotation of the lead screw (2230), the screw pulley housing (2240) can move in a corresponding direction, for example, and can descend. Accordingly, the wheel (2250) positioned on one side of the screw pulley housing (2240) moves while rolling on the surface of the leg support (2260), causing the leg massage part (2000) to descend.

[0167] FIG. 13 is a drawing for explaining a driving module of a leg massage unit (2000) according to another embodiment of the present invention.

[0168] Referring to FIG. 13, a massage device according to another embodiment of the present invention may include a main frame (1100) forming the skeleton of the massage device, a body massage unit (1000) for massaging a user's body, a leg massage unit (2000) including a first leg massage unit (2000a) corresponding to one leg of the user and a second leg massage unit (2000b) corresponding to the other leg of the user, and a driving module disposed in the body massage unit (1000) for rotating the leg massage unit (2000).

[0169] At this time, the main frame, body massage unit, and leg massage unit may selectively apply the contents regarding the main frame (1100), body massage unit (1000), and leg massage unit (2000) described above, or modify and apply them as needed.

[0170] The first leg massage unit (2000a) and the second leg massage unit (2000b) can be rotated individually, and to this end, the driving module may include a first driving module that rotates the first leg massage unit (2000a) and a second driving module that rotates the second leg massage unit (2000b).

[0171] In the following description of the operation of the leg massage unit (2000) according to the present embodiment, the term "leg massage unit (2000)" refers to the first leg massage unit (2000a) and the second leg massage unit (2000b), and the statement that the leg massage unit (2000) may include a certain configuration may mean that the first leg massage unit (2000a) and the second leg massage unit (2000b) may each include such configuration.

[0172] In addition, in describing the driving module according to the present embodiment, the term "driving module" refers to the first driving module and the second driving module, and the statement that the driving module may include a certain configuration may mean that the first driving module and the second driving module may each include such configuration.

[0173] The driving module according to the present embodiment may be a driving module of the type using an actuator.

[0174] In one embodiment, the driving module may include a leg angle actuator (2310) and a link unit (2320).

[0175] The leg angle actuator (2310) may be a means for generating a force to rotate the leg massage unit (2000) by receiving power. For example, the leg angle actuator (2310) may be a means for rotating the leg massage unit (2000) by receiving power and extending in the longitudinal direction.

[0176] The leg angle actuator (2310) can be placed in the body massage unit (1000) and, for example, connected to the main frame (1100).

[0177] In one embodiment, the leg angle actuator (2310) may be positioned below the leg connecting frame. Accordingly, the leg angle actuator (2310) can efficiently rotate the leg massage unit (2000) and can be efficiently positioned within the internal space of the body massage unit (1000).

[0178] The link unit (2320) may be a means of lifting the leg massage unit (2000) by transmitting the force generated from the leg angle actuator (2310) to the leg massage unit (2000). To this end, the link unit (2320) may be connected to the leg massage unit (2000) and the leg angle actuator (2310).

[0179] In one embodiment, the leg massage unit (2000) may include a leg support unit (2330) disposed on the back surface of the leg massage unit (2000). In this case, the leg support unit (2330) may be connected to a link unit (2320). Accordingly, as the leg angle actuator (2310) extends and retracts, the link unit (2320) can move together, and as the leg support unit (2330) connected to the link unit (2320) moves, the leg massage unit (2000) can rotate.

[0180] The link unit (2320) may be formed as a joint structure. For example, the link unit (2320) may include a bend portion (2321), and the link unit (2320) may be folded based on the bend portion (2321). Accordingly, the leg angle actuator (2310) can stably rotate the leg massage portion (2000).

[0181] Specifically, the link unit (2320) can be connected to the main frame (1100), the leg angle actuator (2310), and the leg support (2330). At this time, each connecting part of the link unit (2320) can be connected so as to be rotatable. Accordingly, when the leg angle actuator (2310) extends, the link unit (2320) folds based on the bending part (2321), and the part connected to the main frame (1100), the part connected to the leg angle actuator (2310), and the part connected to the leg support (2330) can each rotate.

[0182] FIG. 14 is a diagram for explaining the principle of rotation of the leg massage part (2000) of FIG. 13.

[0183] Referring to FIG. 14, the link unit (2320) can be unfolded or folded simultaneously with rotation by driving the leg angle actuator (2310), and thereby the leg massage unit (2000) can be lifted or lowered.

[0184] Specifically, referring to FIG. 14, when the leg angle actuator (2310) extends, the link unit (2320) connected to the leg angle actuator (2310) can rotate clockwise to be parallel to the leg angle actuator (2310), and accordingly, the link unit (2320) can rotate in a direction away from the main frame (1100). At the same time, the link unit (2320) can be unfolded with respect to the bending portion (2321), and as the link unit (2320) unfolds, the leg massage portion (2000) can be lifted.

[0185] Conversely, when the leg angle actuator (2310) contracts, the link unit (2320) connected to the leg angle actuator (2310) can rotate in a direction perpendicular to the leg angle actuator (2310), that is, counterclockwise, and accordingly, the link unit (2320) can rotate in a direction closer to the main frame (1100). At the same time, the link unit (2320) can be folded based on the bending portion (2321), and as the link unit (2320) is folded, the leg massage portion (2000) comes down.

[0186] FIG. 15 is a drawing for explaining a driving module of a leg massage unit (2000) according to another embodiment of the present invention, and FIG. 16 is a drawing for explaining the driving of an airbag (2410) of FIG. 15. Specifically, FIG. 16(a) is a drawing schematically illustrating the airbag (2410) in a deflated state, and FIG. 16(b) is a drawing schematically illustrating the airbag (2410) in an inflated state.

[0187] Referring to FIGS. 15 and 16, a massage device according to another embodiment of the present invention may include a main frame (1100) forming the skeleton of the massage device, a body massage unit (1000) for massaging a user's body, a leg massage unit (2000) including a first leg massage unit (2000a) corresponding to one leg of the user and a second leg massage unit (2000b) corresponding to the other leg of the user, and a driving module disposed in the body massage unit (1000) for rotating the leg massage unit (2000).

[0188] At this time, the main frame, body massage unit, and leg massage unit may selectively apply the contents regarding the main frame (1100), body massage unit (1000), and leg massage unit (2000) described above, or modify and apply them as needed.

[0189] The first leg massage unit (2000a) and the second leg massage unit (2000b) can be rotated individually, and to this end, the driving module may include a first driving module that rotates the first leg massage unit (2000a) and a second driving module that rotates the second leg massage unit (2000b).

[0190] In the following description of the operation of the leg massage unit (2000) according to the present embodiment, the term "leg massage unit (2000)" refers to the first leg massage unit (2000a) and the second leg massage unit (2000b), and the statement that the leg massage unit (2000) may include a certain configuration may mean that the first leg massage unit (2000a) and the second leg massage unit (2000b) may each include such configuration.

[0191] In addition, in describing the driving module according to the present embodiment, the term "driving module" refers to the first driving module and the second driving module, and the statement that the driving module may include a certain configuration may mean that the first driving module and the second driving module may each include such configuration.

[0192] The driving module according to the present embodiment may be a driving module of the type using an airbag (2410).

[0193] In one embodiment, the driving module may include an airbag (2410) and an airbag support (2420). Additionally, the leg massage unit (2000) may include a leg support (2430) disposed on the back of the leg massage unit (2000). The leg support (2430) may be in direct contact with the airbag (2410).

[0194] The airbag (2410) may be a means of expanding by supplying air or contracting by releasing air. For example, the airbag (2410) may be configured to expand in a fan-like direction when air is supplied. Conversely, the airbag (2410) may be configured so that the expanded portion contracts and folds when air is released.

[0195] Accordingly, the airbag (2410) is placed on the back of the leg massage unit (2000) and can rotate the leg massage unit (2000) by expanding and contracting.

[0196] The airbag support member (2420) may be provided in the body massage member (1000) and may be a means for supporting the airbag (2410). For example, the airbag support member (2420) may be connected to the main frame (1100) and positioned on the lower side of the leg connecting frame.

[0197] The airbag (2410) can be connected to and supported by the airbag support (2420), and when air is supplied, the part connected to the airbag support (2420) is fixed and the remaining part can be expanded in a direction away from the main frame (1100).

[0198] At this time, the airbag (2410) can be connected to the airbag support (2420) such that the part that unfolds according to FIG. 15 is positioned below, and the part that becomes the axis of the fan shape is positioned above. Thus, as air is supplied, it can expand in a direction that stably pushes up the leg massage part (2000).

[0199] As an optional embodiment, the airbag (2410) may be coupled such that one side contacts the airbag support (2420). For example, one side of the airbag (2410) may be in full contact with the airbag support (2420), and accordingly, when the airbag (2410) inflates, the airbag (2410) is firmly fixed to the airbag support (2420), so that the leg massager (2000) can be stably lifted.

[0200] FIG. 17 is a diagram for explaining the principle of rotation of the leg massage part (2000) of FIG. 15.

[0201] Referring to FIG. 17, as an optional embodiment, a plurality of airbags (2410) may be provided, and the airbag support (2420) may be formed in a stepped shape corresponding to the number of airbags (2410) provided.

[0202] Based on FIG. 17, multiple airbags (2410) may be arranged in a vertical direction, and the airbag support (2420) may have a step formed in a direction that moves away from the leg massage unit (2000) as it goes from bottom to top. At this time, the smaller the angle formed between the leg massage unit (2000) and the airbag support (2420), the more the airbag (2410) placed relatively lower is involved.

[0203] For example, when the leg massage unit (2000) is lifted from a state where it is folded to the maximum, the lowest airbag (2410) may inflate. After that, once the leg massage unit (2000) is lifted beyond a certain point, the lowest airbag (2410) becomes separated from the leg support (2430) of the leg massage unit (2000), and from then on, the airbag (2410) positioned above it inflates to lift the leg massage unit (2000). Therefore, the angle at which the leg massage unit (2000) can be lifted to the maximum can be determined by the airbag (2410) positioned at the top.

[0204] Conversely, when the leg massage unit (2000) is lowered, the airbag (2410) placed at the top may be involved. For example, when the leg massage unit (2000) is raised to its maximum height, only the airbag (2410) placed at the top comes into contact with the leg massage unit (2000). Subsequently, as the airbag (2410) placed at the top contracts, the leg massage unit (2000) is lowered, and when the leg massage unit (2000) is lowered beyond a certain angle, the airbag (2410) placed at the next level and the leg support unit (2430) come into contact. In this way, as the leg massage unit (2000) is lowered, the leg support unit (2430) comes into contact with the airbag (2410) placed at the lower level.

[0205] FIG. 18 is a drawing for explaining a leg massage unit (2000) according to another embodiment of the present invention.

[0206] Referring to FIG. 18, the massage device according to the present embodiment may include a cushioning member (2510). For example, the leg massage part (2000) may include a cushioning member (2510) disposed on the back surface.

[0207] The cushioning member (2510) is positioned on the back of the leg massage unit (2000) and may be a means to mitigate the impact or vibration caused by hitting the body massage unit (1000) when the leg massage unit (2000) is completely folded.

[0208] In one embodiment, the cushioning member (2510) may be made of an elastic material. For example, the cushioning member (2510) may be made of at least one of rubber, synthetic resin, and sponge. Thus, vibrations or shocks caused by the leg massage part (2000) colliding with the body massage part (1000) when the leg massage part (2000) is folded can be mitigated. However, the material forming the cushioning member (2510) is not limited to this, and any material that has elasticity and can mitigate shock can be used.

[0209] In one embodiment, the cushioning member (2510) may be disposed on the back surface of the first leg massage part (2000a) and the second leg massage part (2000b), respectively. Accordingly, vibrations or shocks caused by folding can be mitigated for each of the first leg massage part (2000a) and the second leg massage part (2000b).

[0210] The leg massage unit (2000) may further include a position adjustment sensor (1810). For example, the position adjustment sensor (1810) may be a sensor for setting the initial position of the leg massage unit (2000).

[0211] Specifically, the initial position may be the position where the leg massage unit (2000) is in a folded state. At this time, the position adjustment sensor (1810) can recognize whether the folded leg massage unit (2000) is in a preset position at a specific time.

[0212] In one embodiment, the position adjustment sensor (1810) can recognize whether the first leg massage part (2000a) and the second leg massage part (2000b) are positioned side by side. That is, the position adjustment sensor (1810) can recognize whether the first leg massage part (2000a) and the second leg massage part (2000b) are rotated to have a deviation from each other when they are in their initial positions.

[0213] To this end, a position adjustment sensor (1810) may be provided in each of the first leg massage unit (2000a) and the second leg massage unit (2000b). Specifically, the position adjustment sensor (1810) may be positioned on the side facing each other between the first leg massage unit (2000a) and the second leg massage unit (2000b).

[0214] As an optional embodiment, each position adjustment sensor (1810) placed in the first leg massage unit (2000a) and the second leg massage unit (2000b) can recognize each other, and if it is recognized that they are not facing each other at the correct position, the position adjustment sensor (1810) can recognize that the two leg massage units (2000) are misaligned.

[0215] In one embodiment, the leg massage unit (2000) may further include a position setting frame (2520).

[0216] The position setting frame (2520) may be a means for setting the first leg massage part (2000a) and the second leg massage part (2000b) to be positioned correctly.

[0217] In one embodiment, the position setting frame (2520) may be connected to and positioned on the main frame (1100), specifically positioned on the lower side of the main frame (1100), and positioned at a location corresponding to the heel portion of the leg massage part (2000).

[0218] Accordingly, when the leg massage unit (2000) comes into contact with the position setting frame (2520), the leg massage unit (2000) can be determined to be in the initial position.

[0219] As an optional embodiment, the position setting frame (2520) may be positioned in contact with the cushioning member (2510). Thus, when the leg massage unit (2000) is folded and returns to its initial position, the cushioning member (2510) may come into contact with the position setting frame (2520). That is, by the cushioning member (2510) coming into contact with the position setting frame (2520), the impact caused by the folding of the leg massage unit (2000) can be mitigated, and at the same time, the initial position of the leg massage unit (2000) can be set.

[0220] FIG. 19 is a drawing for explaining an embodiment of a leg massage unit (2000) including a safety sensor, FIG. 20 is a drawing showing only one side of the leg massage unit (2000) of FIG. 19, FIG. 21 is a drawing showing the leg massage unit (2000) of FIG. 19 viewed from a different viewing angle.

[0221] The leg massage unit (2000) according to the present embodiment may further include at least one safety sensor that detects that at least a part of the user's body is trapped.

[0222] When the leg massage unit (2000) rotates, the user's body may get stuck in a specific location of the massage device. For example, the user's body may get stuck between both sides of the leg massage unit (2000) and the body massage unit (1000), or between the first leg massage unit (2000a) and the second leg massage unit (2000b), etc.

[0223] To solve this, the leg massage unit (2000) may further include a safety sensor that recognizes that at least a part of the user's body is caught in the aforementioned position.

[0224] Referring to FIG. 19, as in one embodiment, the safety sensor may include a first safety sensor (1820) disposed on both sides of the leg massage unit (2000). Specifically, the first safety sensor (1820) may be disposed on the outer side of the first leg massage unit (2000a) and the outer side of the second leg massage unit (2000b), respectively, and may be disposed at a position corresponding to the outer side of the calf among the sides of the first leg massage unit (2000a) and the second leg massage unit (2000b).

[0225] Accordingly, the first safety sensor (1820) can detect that the user's body is trapped between the leg massage unit (2000) and the body massage unit (1000) as the leg massage unit (2000) rotates.

[0226] Referring to FIG. 20, as in one embodiment, the safety sensor may include a second safety sensor (1830) positioned between the first leg massage unit (2000a) and the second leg massage unit (2000b). Specifically, the second safety sensor (1830) may be positioned on the inner surfaces of the first leg massage unit (2000a) and the second leg massage unit (2000b) facing each other, and may be positioned at a location corresponding to the inner calf among the inner surfaces of the first leg massage unit (2000a) and the second leg massage unit (2000b).

[0227] As an optional embodiment, when the leg massage unit (2000) corresponding to the user's right leg is the first leg massage unit (2000a) and the leg massage unit (2000) corresponding to the user's left leg is the second leg massage unit (2000b), the second safety sensor (1830) may be positioned on the upper left and lower right sides of the inner calf of the first leg massage unit (2000a) with respect to FIG. 20. Additionally, the second safety sensor (1830) may be positioned on the inner calf of the second leg massage unit (2000b) at a location corresponding to the first leg massage unit (2000a).

[0228] Therefore, when the first leg massage unit (2000a) and the second leg massage unit (2000b) rotate individually so as to intersect each other, the user's body being trapped can be quickly recognized. For example, if the first leg massage unit (2000a) is in a folded state and the second leg massage unit (2000b) is in an unfolded state and the first leg massage unit (2000a) and the second leg massage unit (2000b) rotate so as to intersect each other, the user's body first comes into contact with the part where the second safety sensor (1830) is positioned on the upper left of the first leg massage unit (2000a) based on FIG. 20, and the second leg massage unit (2000b) first comes into contact with the part where the second safety sensor (1830) is positioned on the lower side. Therefore, the second safety sensor (1830) can recognize this before the user's body gets trapped beyond a certain point, thus ensuring the user's safety.

[0229] In one embodiment, the safety sensor may include a third safety sensor (1840) disposed on the inner side of the foot massage section. Specifically, the third safety sensor (1840) may be disposed on the inner surface facing each other of the first leg massage section (2000a) and the second leg massage section (2000b), respectively, and may be disposed on the inner surface of the foot massage section of the first leg massage section (2000a) and the foot massage section of the second leg massage section (2000b), respectively.

[0230] Accordingly, if the user's body is trapped between the foot massage part of the first leg massage part (2000a) and the foot massage part of the second leg massage part (2000b), the third safety sensor (1840) can quickly detect this.

[0231] As an optional embodiment, the third safety sensor (1840) may be positioned to have a length along the instep length direction of the foot massager. Thus, it is possible to detect if the user's body is trapped at any location between the foot massager of the first leg massager (2000a) and the foot massager of the second leg massager (2000b).

[0232] Referring to FIG. 21, in one embodiment, the safety sensor may include a fourth safety sensor (1850) disposed on the back surface of the leg massage unit (2000). Specifically, the fourth safety sensor (1850) may be disposed on the back surface of the first leg massage unit (2000a) and the back surface of the second leg massage unit (2000b), respectively, and may be disposed at a position corresponding to the back surface of the calf of the first leg massage unit (2000a) and the second leg massage unit (2000b).

[0233] Accordingly, the fourth safety sensor (1850) can detect that the user's body is trapped between the first leg massage part (2000a) and the second leg massage part (2000b) when the first leg massage part (2000a) and the second leg massage part (2000b) rotate to cross each other.

[0234] As an optional embodiment, a plurality of fourth safety sensors (1850) may be disposed on the back surface of the first leg massage unit (2000a) and the second leg massage unit (2000b). Accordingly, when the leg massage unit (2000) is folded from an unfolded state, it is possible to detect more quickly and precisely that the user's body is trapped between the back surface of the leg massage unit (2000) and the body massage unit (1000).

[0235] In one embodiment, the safety sensor may include a fifth safety sensor (1860) disposed on the bottom surface of the foot massage section. Specifically, the fifth safety sensor (1860) may be disposed on the bottom surface of the foot massage section of the first leg massage section (2000a) and the foot massage section of the second leg massage section (2000b), respectively, and may be disposed at a position corresponding to the soles of the feet of the foot massage section of the first leg massage section (2000a) and the foot massage section of the second leg massage section (2000b).

[0236] Accordingly, the fifth safety sensor (1860) can detect when the leg massage unit (2000) is lowered while in a lifted state that the user's body is trapped between the bottom surface of the foot massage unit and the ground or between the bottom surface of the foot massage unit and the body massage unit (1000).

[0237] In this way, the leg massage unit (2000) includes safety sensors to prevent safety accidents that may occur when the user's body gets caught. In particular, the leg massage unit (2000) includes multiple safety sensors at multiple locations, thereby enabling it to quickly and precisely detect when the user's body gets caught at any location.
