[0002] Massage refers to a medical adjuvant therapy that adjusts the body by applying various mechanical stimulations to a local part of the body of a massage subject, such as kneading, pressing, stretching, patting, or moving the body, which helps blood circulation and relieves fatigue. Due to the increasing stress and irregular lifestyle of modern people, the demand for relieving muscle tension and fatigue through massage has increased sharply. However, since receiving the service of a masseur actually incurs high economic costs and time limitations, as an alternative, the demand for massage devices or equipment that can provide artificial massage functions has increased significantly.

[0003] In particular, the ankles and legs are prone to accumulating fatigue and tension, so it is essential to perform stretching and rotational movements to relieve muscle and joint stiffness. Existing massage devices are mainly developed with simple pressing and vibration functions, and there are limitations in concentrating on stimulating specific parts. Regarding the legs and ankles, stretching and rotational movements that maintain joint flexibility and relieve muscle fatigue are important, but there is a lack of technology to effectively achieve these movements.

[0004] In addition, existing leg massage devices have tried to rotate and stretch the ankles, but they require a separate motor, resulting in a complex structure and occupying space, and there are difficulties in control and maintenance. Therefore, there is a need for a flexible structure that can provide the functions of simply rotating and stretching the ankles through one motor while allowing the ankles to move freely in multiple directions.

The audio output unit 1500 can output a sound signal received through a network (not shown) or stored in an internal / external storage medium (not shown).

[0121] For example, the audio output module 1500 can output a sound source controlled based on the user terminal through a network connection with the user terminal (e.g., a Bluetooth connection, etc.). In addition, the audio output module 1500 can output any form of sound signal generated in association with the operation of the massage device 100.

[0122] The massage device 100 according to an embodiment of the invention may include a network connection unit 1600. The network connection unit 1600 can communicate with the modules inside the massage device 100, an external massage device 100, and / or a user terminal through any form of network.

[0123] The network connection unit 1600 may include a wired / wireless connection module for connecting to a network. As wireless connection technologies, for example, Wireless LAN (WLAN) (Wi-Fi), Wirelessbroadband (Wibro), World Interoperability for Microwave Access (Wimax), High Speed Downlink Packet Access (HSDPA), etc. may be adopted.

[0124] As wired connection technologies, for example, Digital Subscriber Line (XDSL), Fibers to the home (FTTH), Power Line Communication (PLC), etc. may be utilized. Additionally, the network connection unit 1600 may include a short-range communication module capable of sending and receiving data with some devices or terminals in the vicinity. For example, as short range communication technologies, Bluetooth, Radio Frequency Identification (RFID), infrared Data Association (IrDA), Ultra Wideband (UWB), ZigBee, etc. may be used, but it is not limited thereto.

[0125] As described above, the massage device 100 according to an embodiment of the invention may include a massage module 1700. That is, the massage module 1700 is a structure that provides a mechanical stimulus to the user, and the massage module 1700 may move along the frame unit 1100.

[0126] The massage device 100 according to an embodiment of the present invention may include a main frame 1100. As shown by Figures 1 to 3 the above, the main frame 1100 may provide a path along which the massage module 1700 can move.

[0127] The control unit 1200 may provide a massage by controlling the operation of the massage module 1700 to apply a mechanical stimulus to the user.

[0128] The control unit 1200 may move the massage module 1700 in directions such as the X-axis, Y-axis, and Z-axis. The control unit 1200 may move the massage ball forward or backward on the X-axis, Y-axis, and Z-axis. Alternatively, the control unit 1200 may rotate the massage ball around the X-axis, Y-axis, and Z-axis.

[0129] According to an embodiment of the invention, the massage device 100 may include a sensor unit 1800. At this time, the sensor unit 1800 may include at least one sensor. For example, the sensor unit 1800 may include a touch sensor, a pressure sensor, an infrared sensor, an LED sensor, a light sensor, a Hall sensor, an electrostatic sensor, etc., but is not limited thereto.

[0130] The sensor unit 1800 can be used to obtain various information. For example, the sensor unit 1800 can be used to identify the user. That is, information such as whether the user is seated, the user's body shape, and whether there are abnormalities in the user's body can be obtained. As another example, the sensor unit 1800 can be used to obtain biological information. That is, fingerprint information, face information, voice information, iris information, weight information, electrocardiogram information, body composition information, etc. can be obtained, but is not limited thereto, and can include various biological information.

[0131] As an alternative embodiment, the massage device 100 can detect the contact area and / or contact position with the user through the sensor unit 1800.

[0133] In addition, the massage device 100 can provide personalized massage according to the information obtained through the sensor unit. For example, when the massage device 100 provides shoulder massage, the massage device 100 identifies the user's shoulder position according to the information obtained through the sensor unit 1800, and can provide shoulder massage to the user according to the identification result.

[0134] The leg massage unit 2000 can be a structure for massaging the user's legs. A leg accommodation space for accommodating the user's legs can be formed in the leg massage unit 2000. Refer to Figure 1 , multiple leg massage units 2000 can be provided, and the user's right foot and left foot can be respectively accommodated in the multiple leg massage units 2000A, 2000B.

[0135] Specifically, each of the multiple leg massage units 2000A, 2000B may include a foot massage unit 2200 and a calf massage unit 2100, and can be respectively inserted, placed and accommodated by the user's right foot and left foot.

[0136] Figure 4 is a view showing the leg massage unit of the massage device of the present invention, Figure 5 is a view showing the lower region of the foot massage unit of the massage device of the present invention, Figure 6 is a view showing the decomposition of each structure of the lower region of the foot massage unit forming Figure 5 of.

[0137] Reference Figures 4 to 6 The leg massage part 2000 according to the present invention may include a calf massage part 2100 and a foot massage part 2200, and the foot massage part 2200 includes a foot housing 2201 into which the user's foot can be inserted. A structure for driving the foot housing 2201 to support the user's ankle movement is provided at the lower side of the foot housing 2201. This will be described in detail below.

[0138] The foot massage part 2200 is composed of several main components to provide various rotation and stretching movements to the ankle. The foot massage part 2200 includes a first rotation shaft 2211 and a second rotation shaft 2212 responsible for rotation, and is equipped with a rotation plate 2220 and a drive transmission part 2240 for effectively transmitting the motion of these rotation shafts.

[0139] It also includes a support plate 2230 that fixes the foot and gives stability to the movement, and a ball joint 2250 that allows the foot to move freely. Such components are stably supported by a bottom plate 2261 located at the lower part of the foot massage part 2200 and a fixed shaft 2262 fixed thereto, and each component is organically combined to enable smooth foot massage action.

[0140] The first rotating shaft 2211 is a component of the foot massage part 2200 of the present invention that effectively realizes the rotation and stretching movement of the ankle. The first rotating shaft 2211 is meshed with the power gear 2202 driven by the motor, and directly receives the rotation force from the motor to rotate in the clockwise direction or counterclockwise direction. The rotation force is transmitted to the support plate 2230 and the foot housing 2201 through the drive transmission part 2240, so that the foot housing can flexibly move according to the ankle.

[0141] The first rotating shaft 2211 is designed as a hollow structure, and the second rotating shaft 2212 can be inserted into the inside thereof, so that a compound rotation and stretching movement can be performed, thereby supporting various movements of the ankle. The first rotating shaft 2211 and the second rotating shaft 2212 are connected at the upper part of the first rotating shaft 2211 through the second clutch bearing 2272, and have a structure in which the two shafts can operate independently or in conjunction.

[0142] The first rotating shaft 2211 is also supported by a fixed shaft 2262 fixed to a bottom plate 2261, which is configured as a lower support portion. The first rotating shaft 2211 is connected to the fixed shaft 2262 via a bearing 2263, so that the first rotating shaft 2211 rotates smoothly.

[0143] The first rotating shaft 2211 and the rotating plate 2220 are coupled by a first clutch bearing 2271. When rotating in a specific direction (e.g., when rotating counterclockwise), the rotating plate rotates together and transmits the rotational force to the support plate 2230 and the foot housing 2201. When rotating in the opposite direction (e.g., when rotating clockwise), other motions can be achieved by fixing the rotating plate 2220. The socket 2252 of the ball joint 2250 is rotatably coupled to the upper portion of the first rotating shaft 2211, thereby supporting the free movement of the foot housing 2201.

[0144] Figure 7 (a) to (c) are diagrams for explaining the driving of the clutch bearing according to an embodiment of the present invention. Referring to Figure 7 (a) to (c), the structure of the clutch bearing applicable to the present invention will be described as follows.

[0145] The clutch bearing 2270 according to an embodiment of the present invention includes first to third clutch bearings 2271 to 2273. The first clutch bearing 2271 and the third clutch bearing 2273 can transmit the rotational force when rotating counterclockwise, while the second clutch bearing 2272 can transmit the rotational force when rotating clockwise.

[0146] As Figure 7 shown in (a) of, the clutch bearing 2270 may include an inner ring 2270a, an outer ring 2270b, rollers 2270c disposed between the inner ring 2270a and the outer ring 2270b, and a spring 2270d connecting the inner ring 2270a and the rollers 2270c.

[0147] Taking the second clutch bearing 2272 as an example for explanation. As shown in (b) of, when the inner ring 2270a rotates counterclockwise, the space between the outer ring 2270b and the inner ring 2270a decreases. In this case, since the space cannot be less than the outer diameter of the rollers 2270c, the outer ring 2270b cannot rotate. On the contrary, as shown in (c) of Figure 7 , when the inner ring 2270a rotates clockwise, the space between the outer ring 2270b and the inner ring 2270a is maintained constant by the spring 2270d. In this case, the outer ring 2270b can rotate. Figure 7 That is, according to an embodiment of the present invention, the second clutch bearing 2272 can be designed to transmit only clockwise rotation and not counterclockwise rotation.

[0148] On the other hand, contrary to the second clutch bearing 2272, the first and third clutch bearings 2271, 2273 can be designed to transmit only counterclockwise rotation and not clockwise rotation.

[0149] ​

[0150] The detailed description of the first to third clutch bearings 2271 to 2273 will be described later together with the related structural description.

[0151] Refer again Figure 5 , the second rotating shaft 2212 is inserted into the hollow structure of the first rotating shaft 2211, so that the two rotating shafts can rotate in conjunction or independently. The second rotating shaft 2212 is connected to the first rotating shaft 2211 through the second clutch bearing 2272, and the second clutch bearing 2272 transmits the rotational force only when the second rotating shaft 2212 rotates in the clockwise direction. On the contrary, the first clutch bearing 2271 located between the first rotating shaft 2211 and the rotating plate 2220 transmits the rotational force only when it rotates in the counterclockwise direction.

[0152] That is, the first clutch bearing 2271 transmits the rotation force to the rotating plate 2220 only when rotating counterclockwise, and the rotating plate 2220 is fixed when rotating clockwise. On the contrary, the second clutch bearing 2272 transmits the rotation force of the first rotating shaft 2211 to the second rotating shaft 2212 only when rotating clockwise.

[0153] As described above, by setting the rotation allowing directions of the first clutch bearing 2271 and the second clutch bearing 2272 to be different, the second rotation shaft 2212 can operate together with the first rotation shaft 2211 or can independently perform rotational motion relative to the first rotation shaft 2211 .

[0154] The rotating plate 2220 is an element for rotating and stretching the ankle in the leg massage part 2200 of the present invention, and is designed to receive only a rotation force in a specific direction when the first rotating shaft 2211 is coupled to the hollow portion of the rotating plate 2220 .

[0155] The rotating plate 2220 is a component for realizing the rotation and stretching movement of the ankle in the foot massage part 2200, and receives a driving force through the first rotating shaft 2211. A first clutch bearing 2271 is coupled between the first rotating shaft 2211 and the rotating plate 2220, so that the rotation force is transmitted to the rotating plate 2220 only when the first rotating shaft 2211 rotates in the counterclockwise direction. With this structure, the rotating plate 2220 selectively rotates according to the rotation direction of the first rotating shaft 2211.

[0156] A support plate 2230 is provided on the upper side of the rotating plate 2220 to support the foot housing 2201. The drive transmission unit 2240 is located between the rotating plate 2220 and the support plate 2230, and is designed to transmit the rotational movement of the rotating plate 2220 to the support plate 2230 and then to the foot housing 2201. When the rotating plate 2220 rotates, the drive transmission unit 2240 can convert its movement to the support plate 2230 to assist the foot housing 2201 in performing stretching and rotational movements.

[0157] The support plate 2230 is disposed on the upper side of the rotating plate 2220. While stably supporting the foot housing 2201, it performs rotational and swinging movements according to the rotation direction of the first rotation axis 2211.

[0158] When the first rotation axis 2211 rotates counterclockwise, the support plate 2230 rotates by receiving power from the rotating plate 2220. When the first rotation axis 2211 rotates clockwise, since the rotating plate 2220 is fixed, only a swinging movement is performed. At this time, the swinging movement enables the ankle to move smoothly through the meshing between the rack 2243 and the semi-circular gear 2244.

[0159] A plurality of balls 2203 installed on the foot housing 2201 abut against the upper surface of the support plate 2230 to support the foot housing 2201, and a semi-circular gear 2244 is installed on the lower surface of the support plate 2230. The semi-circular gear 2244 is designed to mesh with the rack 2243 connected to the slider 2242, enabling the support plate 2230 to perform a swinging movement. Thus, the angle of the ankle can be adjusted, and the massage effect can be improved through the swinging movement.

[0160] Figure 8 It is a diagram for explaining each structure of the drive transmission unit provided between the rotating plate and the support plate in the foot massage unit of the present invention.

[0161] Refer to Figure 8 As shown in the figure, the drive transmission unit 2240 is provided between the rotating plate 2220 and the support plate 2230, and functions to transmit rotational or swinging movements to the support plate 2230 according to the rotation direction of the first rotation axis 2211. The drive transmission unit 2240 includes a guide portion 2241, a slider 2242, a rack 2243, and a semi-circular gear 2244, and each component element enables various movements of the support plate 2230 according to the rotation direction of the first rotation axis 2211.

[0162] Specifically, the guiding portion 2241 is fixed to the rotating plate 2220, and the guiding slider 2242 can move left and right along the guidance of the guiding portion 2241. The guiding portion 2241 can be formed to extend along the length direction of both sides of the rotating plate 2220, so as to provide a path along which the slider 2242 can move stably. Thus, the slider 2242 can perform a linear motion on the rotating plate 2220.

[0163] A rack 2243 is coupled to the slider 2242, and the rack 2243 meshes with a semi-circular gear 2244 installed at the lower part of the support plate 2230. Through the meshing of the rack 2243 and the semi-circular gear 2244, the linear motion of the slider 2242 is transmitted to the semi-circular gear 2244, which helps to adjust the angle of the support plate 2230, thereby guiding the swinging motion of the support plate 2230.

[0164] When the first rotating shaft 2211 rotates in the clockwise direction, the rack 2243 and the semi-circular gear 2244 mesh, and a swinging motion is performed by adjusting the angle of the support plate 2230. Conversely, when the first rotating shaft 2211 rotates in the counterclockwise direction, the rotating plate 2220 and the support plate 2230 rotate together, so that the support plate 2230 performs a rotating motion.

[0165] A detailed drive of the support plate 2230 according to the rotation direction of the first rotating shaft 2211 will be described later.

[0166] Referring again to Figure 6 , the ball joint 2250 will be described as follows.

[0167] The ball joint 2250 of the present invention functions to allow the foot housing 2201 to move relative to the support plate 2230 between the foot housing 2201 and the support plate 2230, and is composed of a ball head 2251 and a socket 2252.

[0168] The ball head 2251 is composed of a shaft 2251a and a ball 2251b portion coupled to the lower end of the shaft 2251a. The shaft 2251a forms the shaft of the foot housing 2201 and functions to support the movement of the foot housing 2201. Through this coupling, the movement of the foot housing 2201 is transmitted through the ball joint 2250.

[0169] The ball 2251b at the lower end is located at the lower part of the ball head 2251 and is coupled to the socket 2252. The ball 2251b portion is designed to be inserted into the upper part of the socket 2252 and can rotate at various angles in the socket 2252, so as to smoothly support the tilting or rotating movement of the foot housing 2201. The socket 2252 is shaped around the ball 2251b, and an internal space is formed to match the shape of the ball 2251b, so that it can rotate freely.

[0170] The socket 2252 is a component of the ball joint 2250, designed to accommodate the ball 2251b, which is the lower end part of the ball head 2251, and rotatably support it. The socket 2252 is combined with the support plate 2230, enabling the ball head 2251 to rotate and move at various angles, and facilitating the smooth rotation and angle adjustment of the foot housing 2201.

[0171] In addition, the socket 2252 is inserted into the hollow of the second rotating shaft 2212, and this combination is achieved through the third clutch bearing 2273. The third clutch bearing 2273 is installed between the socket 2252 and the second rotating shaft 2212, transmitting the rotational force only when rotating in a specific direction, and transmitting only the counterclockwise rotation, the same as the first clutch bearing 2271. This is contrary to the function of the second clutch bearing 2272, allowing rotation only in the desired direction within the system.

[0172] The lower part of the socket 2252 is also rotatably combined with the fixed shaft 2262, enabling the entire ball joint 2250 to perform further rotation around the fixed shaft 2262. With this structure, various movements of the foot housing 2201 are carried out smoothly, and through the combination with the support plate 2230, the rotation and angle adjustment functions of the ankle are more effectively supported.

[0173] Figure 9 Figures (a) and (b) show the motion conversion part of the present invention that converts the rotational force of the first rotating shaft into the linear motion of the sliding block. Figure 9 Each step in Figure (a) corresponds to Figure 9 each step in Figure (b).

[0174] Referring to Figure 9 Figures (a) and (b), the drive transmission part 2240 according to the present invention may include a motion conversion part 2245. The motion conversion part 2245 includes a plurality of gears 2245a for converting the rotational force of the first rotating shaft 2211 into the linear motion of the sliding block 2242. The plurality of gears may include a driving gear 2245a-1 and first and second driven gears 2245a-2, 2245a-3 that mesh with both sides of the driving gear 2245a-1.

[0175] In a state where the driving gear 2245a-1 is combined with the first rotating shaft 2211 in the motion conversion part 2245, it functions to transmit the rotational force of the first rotating shaft 2211 to the first and second driven gears 2245a-2, 2245a-3. The central axis s1 of the driving gear 2245a-1 is designed to be an eccentric structure, such that power is transmitted along an eccentric trajectory during rotation. This eccentric central axis s1 meshes with the driven gears 2245a-2, 2245a-3 and guides the linear motion of the sliding block 2242.

[0176] The first driven gear 2245a-2 and the second driven gear 2245a-3 also have eccentric central axes s2 and s3, and each of the central axes s2 and s3 is fixed to the slider 2242. Through this eccentric design, when the driving gear 2245a-1 rotates, the driven gears move together, and a linear motion in the left-right direction is formed on the slider 2242.

[0177] In particular, the central axis s1 of the driving gear 2245a-1 is formed in the through portion 2242a located at the center of the slider 2242, and the through portion 2242a is designed such that the slider 2242 can move freely in the left-right direction.

[0178] To enable the smooth left-right movement of the slider 2242, the relationship between the center s1 of the driving gear and the centers s2 and s3 of each driven gear is important. In particular, the sum of the distance from the center s1 of the driving gear to the center s2 of the first driven gear and the distance from the center s1 of the driving gear to the center s3 of the second driven gear is always the same as the distance between the center s2 of the first driven gear and the center s3 of the second driven gear.

[0179] In addition, to maintain the smooth meshing of the gears, even during the gear drive process, the center s1 of the driving gear and the centers s2 and s3 of each driven gear should be at the same height. This makes the meshing between the central axes of each gear consistent when the slider 2242 moves horizontally, so that the slider 2242 can move accurately without wobbling. When these two conditions, namely the height consistency and the distance relationship, are met, the slider 2242 performs an accurate and smooth left-right movement, thus ensuring the stable operation of the entire mechanism.

[0180] Figure 10 is a diagram showing Figure 9 the process of transmitting the linear motion of the slider to the swinging motion of the support plate.

[0181] Referring to Figure 10 , the rack 2243 combined with the slider 2242 moves left and right according to the linear motion of the slider 2242, and the rack 2243 meshes with and drives the semi-circular gear 2244 attached to the support plate 2230.

[0182] The rack 2243 serves as a medium for transmitting the linear motion of the slider 2242 to the semi-circular gear 2244, and the semi-circular gear 2244 rotates as the slider 2242 moves left and right. Since the semi-circular gear 2244 is fixed to the lower surface of the support plate 2230, the linear motion of the rack 2243 is converted into the rotational motion of the semi-circular gear 2244, and in this process, the support plate 2230 performs a swinging motion about the first and second rotation axes 2211 and 2212.

[0183] The gear combination as described above can precisely control the movement of the support plate according to the gear ratio of the rack 2243 and the semi-circular gear 2244 and the engagement angle. Therefore, the linear motion of the slider 2242 is converted into the swinging motion of the support plate 2230 through the rack 2243 and the semi-circular gear 2244, thereby enabling the stretching motion of the ankle.

[0184] Refer again to Figure 5 , the operations of the first to third clutch bearings 2271, 2272, and 2273 for performing the swinging motion of the support plate 2230 will be described. This is the core element that enables the support plate 2230 to perform only the swinging motion without rotation.

[0185] First, the first rotating shaft 2211 rotates in the clockwise direction. Therefore, the first clutch bearing 2271 functions as a structure that only transmits rotation in the counterclockwise direction. Since the first clutch bearing 2271 only allows rotation in the counterclockwise direction, when the first rotating shaft 2211 rotates in the clockwise direction, the rotating plate remains in a fixed state. In this fixed state, the slider 2242 moves left and right by the rotational force of the first rotating shaft 2211, and the swinging motion of the support plate 2230 is guided by the semi-circular gear 2244 meshing with the rack 2243.

[0186] The first rotating shaft 2211 is connected to the second rotating shaft 2212 through the second clutch bearing 2272. Contrary to the first clutch bearing 2271, the second clutch bearing 2272 has the characteristic of only allowing rotation in the clockwise direction. Therefore, when the first rotating shaft 2211 rotates in the clockwise direction, the second rotating shaft 2212 also rotates in the clockwise direction through the second clutch bearing 2272.

[0187] The second rotating shaft 2212 is connected to the socket 2252 of the ball joint 2250 through the third clutch bearing 2273. Similar to the first clutch bearing 2271, the third clutch bearing 2273 only transmits rotation in the counterclockwise direction. Therefore, even when the second rotating shaft 2212 rotates in the clockwise direction, the third clutch bearing 2273 does not transmit the clockwise rotation to the socket 2252. As a result, the socket 2252 of the ball joint 2250 remains in a fixed state and does not rotate. Through the ball 2251b moving relative to this fixed socket 2252, the support plate 2230 can perform only the swinging motion without rotation.

[0188] Figure 11 It is a diagram showing the process in which the counterclockwise rotation of the first rotating shaft of the present invention is transmitted to the rotational motion of the support plate.

[0189] Refer to Figure 11, when the first rotating shaft 2211 rotates counterclockwise, this rotational movement is transmitted to the rotating plate 2200 through the first clutch bearing 2271. The first clutch bearing 2271 is configured to transmit only counterclockwise rotation. Therefore, when the first rotating shaft 2211 rotates counterclockwise, the rotating plate 2200 also rotates counterclockwise together.

[0190] The slider 2242 fixed to the rotating plate 2200 rotates in the same direction as the rotating plate 2200 in a state integrated with the rotating plate 2200 without performing separate left - right linear movement. Through this rotational movement, the rack 2243 attached to the slider 2242 rotates together with the rotating plate 2200, and the rack 2243 meshes with the semi - circular gear 2244. Therefore, the rotational movement is transmitted to the semi - circular gear.

[0191] The semi - circular gear 2244 is fixed to the lower surface of the support plate 2230 and performs corresponding rotational movement as the rack 2243 rotates. This rotational movement causes the semi - circular gear 2244 itself to rotate on the horizontal plane. As a result, the rotational movement is transmitted to the support plate 2230. Here, the rotation of the semi - circular gear 2244 refers to the rotational movement on the horizontal plane, not the circumferential rotation of the gear.

[0192] That is, the counterclockwise rotation of the first rotating shaft 2211 is converted into the rotational movement of the support plate 2230 through the rotating plate 2200, the slider 2242, the rack 2243, and the semi - circular gear 2244. Thus, the ankle rotational movement can be achieved.

[0193] Refer again to Figure 5 , the operations of the first to third clutch bearings 2271, 2272, and 2273 for performing this rotational movement of the support plate 2230 will be described.

[0194] First, the counterclockwise rotation of the first rotating shaft 2211 is transmitted to the rotating plate 2200 through the first clutch bearing 2271. Since the first clutch bearing 2271 is configured to transmit only counterclockwise rotation, when the first rotating shaft 2211 rotates counterclockwise, the rotating plate 2200 also rotates counterclockwise.

[0195] The rotating plate 2200 and the slider 2242 are integrated. The slider 2242 rotates together with the rotating plate. In this state, the rack 2243 coupled to the slider 2242 meshes with the semi - circular gear 2244, so that the rotational movement is transmitted to the semi - circular gear 2244. Since the semi - circular gear 2244 is fixed to the support plate 2230, the rotational movement of the rack 2243 is converted into the rotational movement of the support plate 2230.

[0196] The socket 2252 is combined with the support plate 2230, and when the support plate 2230 rotates, the socket 2252 rotates together. The counterclockwise rotation of the socket 2252 is transmitted to the second rotating shaft 2212 through the third clutch bearing 2273. The third clutch bearing 2273 has the characteristic of only transmitting counterclockwise rotation, so the rotational movement of the socket 2252 is only transmitted to the second rotating shaft 2212 and the rotation in other directions is blocked.

[0197] The second rotating shaft 2212 is connected to the first rotating shaft 2211 through the second clutch bearing 2272, and the second clutch bearing 2272 is arranged to only transmit clockwise rotation. Therefore, even if the second rotating shaft 2212 rotates counterclockwise, the power will not be transmitted to the first rotating shaft 2211, and the second rotating shaft 2212 rotates independently. Therefore, the first rotating shaft 2211 and the second rotating shaft 2212 can rotate independently at different speeds from each other.

[0198] The advantage of this structure is that it can operate stably even if the rotation speeds of the support plate 2230 and the rotating plate 2200 are different from each other. Since the support plate 2230 adjusts the rotation speed through the frictional force with the ball 2203 installed on the foot housing 2201, the rotation speed difference is allowed.

[0199] Figure 12 It is a diagram showing the rotational and swinging motions of the support plate of the present invention performed in sequence.

[0200] Refer to Figure 12 , the support plate 2230 alternately performs rotational motion and swinging motion according to the rotation direction of the first rotating shaft 2211.

[0201] First, when the first rotating shaft 2211 rotates counterclockwise, the rotational force is transmitted to the rotating plate 2200 through the first clutch bearing 2271. Since the rotating plate and the slider 2242 are formed as one body, the rack 2243 fastened to the slider transmits the rotational motion to the support plate by driving the semi-circular gear 2244. The semi-circular gear 2244 fixed on the support plate 2230 rotates together with the support plate and performs an ankle motion that makes the foot housing 2250 rotate smoothly.

[0202] After that, when the first rotating shaft rotates clockwise, the first clutch bearing 2271 does not transmit the rotational force to the rotating plate, and the slider 2242 does not move and is located at the position fixed on the rotating plate 2200. In this state, the rack 2243 connected to the slider 2242 meshes with the semi-circular gear 2244, so that the support plate 2230 performs a swinging motion instead of a rotational motion. The swinging motion makes the support plate sway back and forth, thus providing the effect of helping to stretch the ankle through the foot housing 2201.

[0203] Therefore, as Figure 12 shown, the support plate 2230 can sequentially perform a rotational movement and a swinging movement according to the rotational direction of the first rotation axis 2211, thereby providing an ankle rotation and stretching effect.
