Description

[0001] This application is a divisional application of the patent application with application number 2023217553514, application date July 5, 2023, and invention name “Massage Device”. Technical Field

[0002] The utility model relates to a massage device for stretching a user's legs, and more particularly to a massage device for stretching a user's legs through a leg massage part that can move independently. Background Art

[0003] Massage refers to a medical auxiliary therapy that regulates the body changes of the massage object, helps blood circulation and relieves fatigue of the massage object by applying various forms of mechanical stimulation to the body part of the massage object, such as kneading, pressing, stretching, patting or moving a part of the body.

[0004] Due to economic and time reasons, there is an increasing demand for massage devices that provide manual massage functions. As the demand for relieving stiff muscles and eliminating fatigue or stress through massage increases, various massage devices with good time and cost benefits are introduced.

[0005] Recently, people's concern for health has increased, and massage devices have changed from simply providing a massage function to electronic devices that provide a variety of additional functions and / or medical functions, and thus, research on methods of effectively controlling massage devices is still ongoing.

[0006] In particular, since the parts to be massaged, desired stimulation, etc. may differ for each user, research activities on devices and methods for providing massage in an optimized form to each user are increasing.

[0007] As such an example, Korean Patent Publication No. 10-2020-0100561 discloses an example of a massage device divided into a first leg massage part for accommodating the right leg and a second leg massage part for accommodating the left leg, and the first and second leg massage parts are independently driven.

[0008] On the other hand, in the case of the independently driven leg massage parts, since the leg massage parts are independently driven, there is a problem that a part of the user's body is sandwiched between the leg massage parts. This problem may cause a safety accident.

[0009] Therefore, it is necessary to study a massage device that includes an independently driven leg massage part and can prevent safety accidents. Utility Model Content

[0201] For example, the side supporting bracket 1550 may include a side fixing member 1551 and a side rotating member 1552 .

[0202] The side fixing member 1551 may be welded to the leg connection frame 1131b or may be coupled by a separate fastening member. The side fixing member 1551 may be rotatably coupled to one side of the side rotating member 1552. When the side rotating member 1552 rotates so that its end contacts the side fixing member 1551, it may be connected by the fastening member.

[0203] Fig.14A and Fig. 14Bis a diagram showing a process of fastening a center bushing to a center support bracket, Fig. 14C and Fig.14D 2 is a diagram showing a process of fastening a side bushing to a side support bracket.

[0204] Reference Fig.14A and Fig. 14B , a process of fastening the first center bushing 1311 to the center support bracket 1530 is described.

[0205] The first central fixing member 1531a may be combined with the leg connection frame 1131b. For example, the first central fixing member 1531a may be welded to the leg connection frame 1131b in a state where the leg connection frame 1131b is inserted into the leg connection frame insertion groove 1531d-1 formed at one side of the first central fixing member 1531a or may be combined by a separate fastening member.

[0206] When the first central fixing member 1531a is combined with the leg connecting frame 1131b, the first central rotating member 1532a can be rotated upward. For example, the first central rotating member 1532a can be rotatably hinged to the first central fixing member 1531a through the central rotating shaft 1532a-1, and can be rotated upward based on the central rotating shaft 1532a-1. Here, the central rotating shaft 1532a-1 can refer to a separate rotating shaft that rotatably connects the first central fixing member 1531a and the first central rotating member 1532a. However, the central rotating shaft 1532a-1 can also be set as one with either the first central fixing member 1531a or the first central rotating member 1532a.

[0207] The first center bushing 1311 may be seated in the center bushing receiving groove 1531d-5 of the first center fixing member 1531a.

[0208] When the first center bushing 1311 is installed, the first center rotating member 1532a can be rotated downward. At this time, at least a portion of the upper peripheral surface of the first center bushing 1311 can be accommodated in the center bushing fixing groove 1532d of the first center rotating member 1532a. The center bushing accommodating groove 1531d-5 and the center bushing fixing groove 1532d can rotatably support the first center bushing 1311.

[0209] When the first central rotating member 1532a is rotated downward and the end portion contacts the fixing piece 1531d-4 of the first central fixing member, the first central rotating member 1532a may be connected to the fixing piece 1531d-4 by the fastening member.

[0210] The process of fastening the second center bushing 1321 to the center support bracket 1530 is the same as the process of fastening the first center bushing 1311 to the center support bracket 1530 described above.

[0211] Reference Fig. 14B and Fig. 14C , a process of fastening the first side bushing 1312 to the first side support bracket 1550a is described.

[0212] The side fixing member 1551 may be combined with the leg connection frame 1131b. For example, the side fixing member 1551 may be welded to the leg connection frame 1131b or may be combined by a separate fastening member.

[0213] When the side fixing member 1551 is combined with the leg connection frame 1131b, the side rotation member 1552 can be rotated upward. For example, the side rotation member 1552 can be rotatably hinged to the side fixing member 1551 through the side rotation shaft 1552b, and can be rotated upward based on the side rotation shaft 1552b. Here, the side rotation shaft 1552b can refer to a separate rotation shaft that rotatably connects the side fixing member 1551 and the side rotation member 1552. However, the side rotation shaft 1552b can also be provided as a whole with either the side fixing member 1551 or the side rotation member 1552.

[0214] The first side bushing 1312 may be seated in the side bushing receiving groove 1551 a of the side fixing member 1551 .

[0215] When the first side bushing 1312 is installed, the side rotating member 1552 may be rotated downward. At this time, at least a portion of the upper peripheral surface of the first side bushing 1312 may be accommodated in the side bushing fixing groove 1552a of the side rotating member 1552. The side bushing accommodating groove 1551a and the side bushing fixing groove 1552a may rotatably support the first side bushing 1312.

[0216] When the side rotation member 1552 is rotated downward and the end portion is in contact with the side fixing member 1551 , the side rotation member 1552 may be connected to the side fixing member 1551 by the fastening member.

[0217] The process of fastening the second side bushing 1322 to the second side support bracket 1550b is the same as the process of fastening the first side bushing 1312 to the first side support bracket 1550a described above.

[0218] As described above, since the central bushing and the side bushings may be fixed by being seated on the central support bracket 1530 and the side support bracket 1550 and fastened, the leg massage part 1300 may be easily connected to the body massage part 1100 .

[0219] Fig.15 2 is a diagram schematically showing a leg length adjustment module of a leg massage part 2000 according to an embodiment of the present invention. Fig.16 It is a diagram for explaining the length adjustment principle of the leg massage part 2000 according to an embodiment of the present invention. Fig.17 Is magnification Fig.15 Figure 2. Fig.18 Is magnification Fig.15 Figure 2.

[0220] Reference Fig.15 , the massage device 1000 may include a leg length adjustment module 2500 for adjusting the length of the leg massage part 2000. At this time, the leg length adjustment module 2500 may adjust the length of the leg massage part 2000 based on the control of the control part 1400.

[0221] The leg length adjustment module 2500 may include a first leg length adjustment module 2500a and a second leg length adjustment module 2500b.

[0222] The first leg length adjustment module 2500a can be arranged in the first leg massage part 2000a. For example, the first leg length adjustment module 2500a can be arranged at the rear of the first leg massage part 2000a. Specifically, the first leg length adjustment module 2500a can be arranged between the rear of the first leg massage part 2000a and the front of the first leg angle adjustment module 1350a. At this time, the first leg length adjustment module 2500a can be arranged at the inner rear of the first leg massage part 2000a.

[0223] The first leg length adjusting module 2500a can adjust the length of the first leg massaging part 2000a by moving the position of the first leg massaging part 2000a. At this time, the first leg length adjusting module 2500a can adjust the length of the first leg massaging part 2000a based on the length of one leg of the user.

[0224] As an example, the first leg length adjustment module 2500a can adjust the length of the first leg massage part 2000a by moving the first leg massage part 2000a in at least one direction of the upper side (or the upper side direction) and the lower side (or the lower side direction) of the first leg massage part 2000a. At this time, the upper side direction of the first leg massage part 2000a can be a direction from the lower side of the first leg massage part 2000a toward the upper side of the first leg massage part 2000a, and the lower side direction of the first leg massage part 2000a can be a direction from the upper side of the first leg massage part 2000a toward the lower side of the first leg massage part 2000a.

[0225] As another example, the first leg length adjustment module 2500a can move at least one of the first upper leg massage part 2000aa and the first lower leg massage part 2000ab of the first leg massage part 2000a in at least one direction of the upper side and the lower side of the first leg massage part 2000a and adjust (or adjust) the distance between the first upper leg massage part 2000aa and the first lower leg massage part 2000ab, so that the length of the first leg massage part 2000a can be adjusted. At this time, the first upper leg massage part 2000aa can massage the upper part of one leg of the user (for example, the calf). For example, the first upper leg massage part 2000aa can include a massage module such as an air bag and a roller for massaging the upper part of the leg in at least a part of the entire area of ​​the first upper leg massage part 2000aa. The second lower leg massage part 2000ab can massage the lower part of the other leg of the user (for example, the foot). For example, the second lower leg massage part 2000ab may include a massage module such as an air bag and a roller for massaging the lower part of the leg in at least a part of the entire area of ​​the second lower leg massage part 2000ab.

[0226] The second leg length adjustment module 2500b may be included in the second leg massage part 2000b. For example, the second leg length adjustment module 2500b may be arranged at the rear of the second leg massage part 2000b. Specifically, the second leg length adjustment module 2500b may be arranged between the rear of the second leg massage part 2000b and the front of the second leg angle adjustment module 1350b. At this time, the second leg length adjustment module 2500b may be arranged at the inner rear of the second leg massage part 2000b.

[0227] The second leg length adjustment module 2500b can adjust the length of the second leg massage part 2000b by moving the position of the second leg massage part 2000b. At this time, the second leg length adjustment module 2500b can adjust the length of the second leg massage part 2000b based on the length of the other leg of the user.

[0228] As an example, the second leg length adjustment module 2500b can adjust the length of the second leg massage part 2000b by moving the second leg massage part 2000b in at least one direction of the upper side (or the upper side direction) and the lower side (or the lower side direction) of the second leg massage part 2000b. At this time, the upper side direction of the second leg massage part 2000b can be a direction from the lower side of the second leg massage part 2000b toward the upper side of the second leg massage part 2000b, and the lower side direction of the second leg massage part 2000b can be a direction from the upper side of the second leg massage part 2000b toward the lower side of the second leg massage part 2000b.

[0229] As another example, the second leg length adjustment module 2500b can adjust the length of the second leg massage part 2000b by adjusting (regulating) the distance between the second upper leg massage part 2000ba and the second lower leg massage part 2000bb by moving at least one of the second upper leg massage part 2000ba and the second lower leg massage part 2000bb of the second leg massage part 2000b in at least one of the upper direction and the lower direction of the second leg massage part 2000b. In this case, the content of the first upper leg massage part 2000aa can be applied to the second upper leg massage part 2000ba, and the content of the first lower leg massage part 2000ab can be applied to the second lower leg massage part 2000bb.

[0230] In other words, the length of each leg massaging part 2000a, 2000b can be adjusted based on the length of each leg by the adjusting module of each leg massaging part.

[0231] Specifically, refer to Fig.15 and Fig.16 The adjustment modules 2500a, 2500b may include lead screws 2510a, 2510b for adjusting the distance between the upper leg massage parts 2000aa, 2000ba and the lower leg massage parts 2000ab, 2000bb, and leg length adjustment actuators 2520a, 2520b for providing power to the lead screws 2510a, 2510b.

[0232] According to a preferred embodiment, the lead screws 2510a, 2510b may have a spiral formed along the outer surface, and the inner surface of the leg frame 2210 is formed to correspond to the lead screws 2510a, 2510b, and may include a fixing member through which the lead screws 2510a, 2510b pass. In addition, the leg frame 2210 may be provided at the upper leg massage part 2000aa, 2000ba, and the lead screws 2510a, 2510b and the leg length adjustment actuators 2520a, 2520b may be provided at the lower leg massage part 2000ab, 2000bb.

[0233] The lead screws 2510a and 2510b can be rotated by the leg length adjustment actuators 2520a and 2520b, and the lead screws 2510a and 2510b can be rotated while passing through the fixing member in a spiral manner and can move up and down. As a result, the lower leg massage parts 2000ab and 2000bb can approach or move away from the upper leg massage parts 2000aa and 2000ba as the lead screws 2510a and 2510b rotate, so that the distance between the upper leg massage parts 2000aa and 2000ba and the lower leg massage parts 2000ab and 2000bb can be adjusted, and as a result, the lengths of the first leg massage part 2000a and the second leg massage part 2000b can be adjusted.

[0234] Reference Fig.17 , guide rails 2211a, 2211b may be formed on the inner side of the leg frames 2210a, 2210b. And, the first leg massage part 2000a and the second leg massage part 2000b may include guide rollers 2540a, 2540b moving along the guide rails 2211a, 2211b and guide rods 2530a, 2530b for supporting the guide rollers 2540a, 2540b. At this time, one end of the guide rods 2530a, 2530b may be connected to the lower leg massage part 2000ab, 2000bb. Therefore, as the lead screws 2510a, 2510b rotate, the guide rods 2530a, 2530b and the guide rollers 2540a, 2540b may move in the same direction as the lower leg massage part 2000ab, 2000bb.

[0235] On the other hand, the guide rollers 2540a and 2540b can move along the guide rails 2211a and 2211b. Therefore, the guide rollers 2540a and 2540b can guide the lower leg massage parts 2000ab and 2000bb to move in the appropriate direction. Therefore, during the movement of the lower leg massage parts 2000ab and 2000bb, the leg massage parts 2000a and 2000b on both sides can be kept from shaking.

[0236] On the other hand, the guide rails 2211a and 2211b may be formed at a portion of the inner side of the leg frame 2210. Fig.17 The guide rails 2211a and 2211b are formed only on a part of the inner side of the leg frame 2210, and the claws are formed on the remaining part to block the movement of the guide rollers 2540a and 2540b. Therefore, the lower leg massage parts 2000ab and 2000bb can be blocked from moving beyond the limit point, and the lower leg massage parts 2000ab and 2000bb can be prevented from being completely separated from the upper leg massage parts 2000aa and 2000ba.

[0237] On the other hand, in order to more appropriately guide the movement of the guide rods 2530a and 2530b, the leg massage part 2000 may further include guide wheels 2551a and 2551b and guide wheel brackets 2552a and 2552b for accommodating and supporting the guide wheels 2551a and 2551b. Fig.18 , at least one guide wheel 2551a, 2551b can be arranged on the inner side of the guide wheel bracket 2552a, 2552b. The outer surface of the guide wheel 2551a, 2551b can be formed to be recessed inwardly, and the guide rods 2530a, 2530b can be inserted and positioned to correspond to the recessed area. Therefore, when the guide rods 2530a, 2530b move up and down, the guide wheels 2551a, 2551b can support the guide rods 2530a, 2530b so as not to deviate from the moving path. As a result, the guide wheels 2551a, 2551b support the guide rods 2530a, 2530b so that the guide rods 2530a, 2530b do not shake when moving, and can guide the moving path so that the guide rods 2530a, 2530b move in the appropriate direction. Therefore, the lower leg massage parts 2000ab and 2000bb can also be moved in appropriate directions by the guide rods 2530a and 2530b without shaking.

[0238] Fig.19 2 is a diagram showing a leg massage part 2600 according to an embodiment of the present invention.

[0239] The lower leg massage part 2000ab, 2000bb may include a foot massage part 2610, 2630 on one side. Preferably, the foot massage part 2610, 2630 may be provided at the lowermost end or the bottom of the lower leg massage part 2000ab, 2000bb.

[0240] The foot massage part 2610, 2630 may include at least one foot massage module (or a massage unit for massaging the foot) and a foot massage actuator (or a foot driving unit) for driving at least one foot massage module. For example, the first leg massage part 2000a may include a first foot massage part 2610 configured in an area corresponding to the foot (or sole) of one leg of the user. The second leg massage part 2000b may include a second foot massage part 2630 configured in an area corresponding to the foot (or sole) of the other leg of the user.

[0241] The first foot massage part 2610 may include at least one of the first foot massage module 2612 and the second foot massage module 2613. The first foot massage module 2612 and the second foot massage module 2613 are arranged (or configured) in front and rear of the first foot massage part 2610, respectively, and provide massage to the entire sole of one leg of the user. In addition, the first foot massage part 2610 may include a first foot massage actuator 2611 for driving at least one foot massage module. The first foot massage actuator 2611 may be configured in front of the first foot massage part 2610 and in front of the first foot massage module 2612 and drive at least one foot massage module. At this time, the front of the first foot massage part 2610 and the front of the first foot massage module 2612 may be an area corresponding to the toes of one leg in the entire area of ​​the first foot massage part 2610.

[0242] The second foot massage part 2630 may include at least one of the third foot massage module 2632 and the fourth foot massage module 2633. For example, the third foot massage module 2632 and the fourth foot massage module 2633 are arranged (or configured) in front and rear of the second foot massage part 2630, respectively, and provide massage to the entire sole of the other leg of the user. In addition, the second foot massage part 2630 may include a second foot massage actuator 2631 for driving at least one foot massage module. The second foot massage actuator 2631 may be configured in front of the second foot massage part 2630 and in front of the third foot massage module 2632 and drive at least one foot massage module. At this time, the front of the second foot massage part 2630 and the front of the third foot massage module 2632 may be an area corresponding to the toes of the other leg in the entire area of ​​the second foot massage part 2630.

[0243] As described above, the first foot massage part 2610 and the second foot massage part 2630 include two foot massage modules and one foot massage actuator, but are not limited thereto. For example, each of the first foot massage part and the second foot massage part may include a plurality of foot massage modules (e.g., more than three), such as Fig.23 As shown, each foot massage module can be arranged on a straight line. In this case, the straight line can be a line that crosses the sole of the foot. Each of the first foot massage part and the second foot massage part can include a single foot massage actuator to drive all of the multiple foot massage modules through the single foot massage actuator.

[0244] On the other hand, the surface of the foot massage module may be formed with at least one protrusion. Therefore, the foot massage module can provide massage to the sole of the user's foot by rotating.

[0245] Alternatively, the foot massage module may be a roller whose surface is formed in an arc shape. Therefore, the foot massage module may provide massage to the sole of the user's foot by rotating.

[0246] On the other hand, as an optional embodiment, the foot massage actuator may be equipped with a cam. Therefore, the foot massage part can provide acupressure massage to the toe portion of the user using the cam without rolling massage. And, by installing the cam on the foot massage actuator, space efficiency can be improved compared to the case where the foot massage actuator is separately provided.

[0247] Fig. 20 2 is a diagram showing a sensor of a leg massage part according to an embodiment of the present invention. Fig.21 Is magnification Fig. 20 FIG. 4 is a diagram of part D of FIG.

[0248] Reference Fig. 20 and Fig.21 The leg massage part 2000a, 2000b may further include a measurement sensor part for measuring the length of the user's leg. For example, the measurement sensor part may include at least one of a first measurement sensor and a second measurement sensor. The first leg massage part 2000a may include a first measurement sensor for measuring the length of one leg, and the second leg massage part 2000b may include a second measurement sensor for measuring the length of the other leg.

[0249] Preferably, each measurement sensor may include at least one sensor (or sub-measurement sensor) of a first sensor (or a first sub-measurement sensor) and a second sensor (or a second sub-measurement sensor) to measure the length of the user's legs.

[0250] The first sensor may be a capacitive touch sensor. The first sensor may roughly measure the length of the user's legs. Therefore, the length of the user's legs may be measured by the first sensor, and the length of the leg massage parts 2000a, 2000b may be adjusted accordingly.

[0251] The first sensor can measure the leg length by recognizing the user's body contact. Therefore, the first sensor can measure the user's leg length according to whether it is in contact with the user's body, and based on this, the massage device 1000 can adjust the length of the leg massage parts 2000a and 2000b, so the accuracy may be reduced, but the length of the leg massage parts 2000a and 2000b can be adjusted quickly and roughly.

[0252] The second sensor may be a photoelectric sensor PS or a load sensor. The second sensor may be used to accurately measure the length of the user's legs. Therefore, after the massage device 1000 roughly measures the length of the user's legs using the first sensor and adjusts the lengths of the leg massage parts 2000a and 2000b accordingly, the massage device 1000 may accurately measure the length of the user's legs using the second sensor and adjust the lengths of the leg massage parts 2000a and 2000b accordingly.

[0253] As an embodiment, the second sensor may be a photoelectric sensor PS. Preferably, it may be a mechanical photoelectric sensor. As described above, when the photoelectric sensor PS is used, the length of the user's legs can be measured more accurately than when only the first sensor is used. In addition, the photoelectric sensors PS are respectively provided at the leg massage parts on both sides, so that the length of the user's legs on both sides can be measured more accurately.

[0254] For example, the photoelectric sensor PS may be located at the lower side of the leg massage part 2000a, 2000b. Therefore, the photoelectric sensor PS can more accurately measure the leg length of the user. Fig.21 When the photoelectric sensors PS are respectively located at the lower sides of the leg massage parts 2000a and 2000b on both sides and the leg massage parts 2000a and 2000b move, the disc member rotates due to the movement, and the degree of received light that changes with the rotation of the disc member can be measured, thereby accurately measuring the user's leg length.

[0255] However, the present invention is not limited thereto, and of course the user's leg length may be measured by using different types of photoelectric sensors PS or by driving the principle of an existing photoelectric sensor PS.

[0256] As another example, the second sensor may measure the leg length by measuring the load applied to the user's legs.

[0257] For example, the control part 1400 of the massage device 1000 may recognize the length of the leg massage parts 2000a, 2000b when a preset size load is applied to the second sensor while adjusting the distance between the upper leg massage parts 2000aa, 2000ba and the lower leg massage parts 2000ab, 2000bb as the user's leg length. Therefore, the massage device 1000 may recognize the distance of the leg massage parts 2000a, 2000b when a preset size load is applied to the second sensor while finely adjusting the distance between the upper leg massage parts 2000aa, 2000ba and the lower leg massage parts 2000ab, 2000bb as the user's leg length, and in this case, the length of the leg massage parts 2000a, 2000b may be adjusted in a manner corresponding to the user's leg length.

[0258] On the other hand, the first sensor and the second sensor can be located on the lower surface of the leg massage part 2000a, 2000b. Preferably, they can be set at a position corresponding to the bottom of the user's foot. Therefore, the user's leg length can be accurately measured according to the length change of the leg massage part 2000a, 2000b.

[0259] Hereinafter, the operation method of the massage device 1000 will be described in detail.

[0260] The operation method of the massage device 1000 according to the utility model may include: a step of receiving user input; a step of identifying body information related to at least a part of the user's body; a step of adjusting the massage device based on the body information; and a step of providing massage to the user using the adjusted massage device.

[0261] Fig. 22 An example for illustrating a stretching mode according to an embodiment of the present utility model is shown. Fig.23 An example for explaining the reclining action of the control part according to an embodiment of the present invention is shown.

[0262] The massage device 1000 may provide a stretching mode for stretching the user's body. At this time, the stretching mode may be a mode for stretching at least one of the user's legs, waist, and hips (eg, buttocks).

[0263] The control unit 1400 may execute the stretch mode based on the user's response or automatically execute the stretch mode. At this time, the user's response may be a response (or signal) for executing the stretch mode.

[0264] For example, the control unit 1400 controls the movement of the massage device 1000 according to the massage map of the stretching mode, so that the stretching mode can be provided to the user. At this time, the massage map can be preset according to various objects and stored in the memory 1430. The objects can be many, for example, users, managers and / or practitioners and doctors of various enterprises such as manufacturers, sales companies, distribution companies, and development companies of the massage device. The movement of the massage device 1000 can be the movement of various components of the massage device 1000, such as the massage module 1110, at least one of the body massage part 1100, the arm massage part 1200, and the leg massage part 2000.

[0265] Specifically, Fig.23 As shown, the control unit 1400 causes the massage device 1000 to recline (step S2210), and can control the movement of the massage device 1000 according to the massage map of the stretch mode in the state where the massage device 1000 is reclined to provide the stretch mode to the user (step S2230).

[0266] First, the control unit 1400 controls the back angle actuator to tilt the body massage unit 1100 toward the rear of the massage device 1000 and tilt (or rotate) the leg massage unit toward the upper side of the massage device 1000, so that the massage device 1000 can be reclined. The reclining massage device 1000 can be a state in which the body massage unit 1100 is tilted toward the rear of the massage device 1000 and the leg massage unit 2000 is rotated toward the upper side of the massage device 1000.

[0267] For example, the control unit 1400 tilts the body massage unit 1100 toward the rear direction of the body massage unit 1100 based on the preset angle, and tilts the leg massage unit 2000 upward, thereby adjusting the angle of the leg massage unit 2000. At this time, the preset angle may be preset by a variety of objects and stored in the memory 1430 as an angle for adjusting the angle of the body massage unit 1100 and the angle of each leg massage unit.

[0268] The control unit 1400 may adjust the length of each leg massage part based on the length of each leg during (or after) the tilting of each leg massage part. At this time, the control unit 1400 may measure the length of each leg. Since the action of adjusting the length of each leg massage part and the action of measuring the length of each leg are the same as described above, the detailed description thereof will be omitted.

[0269] Thereafter, the control part 1400 controls the motion of the massage device 1000 according to the massage pattern of the stretch mode in the state where the massage device 1000 is reclined, thereby providing the stretch mode to the user.

[0270] In other words, the control part 1400 may provide the stretching mode to the user in a state where the massage device 1000 is reclined.

[0271] Through this, the control part 1400 reclines the massage device 1000 to ensure a space for stretching the user's legs, and thus the leg stretching effect can be increased by eliminating space limitation for stretching the user's legs.

[0272] As described above, the control part 1400 provides the stretching mode to the user in the state where the massage device 1000 is reclined, but is not limited thereto.

[0273] For example, the control unit 1400 can provide a stretching mode after controlling the massage device 1000 to provide a relaxing massage for relaxing the user's body while the massage device 1000 is reclining. At this time, the control unit 1400 can simultaneously perform the action of providing a relaxing massage and the action of measuring the length of each leg.

[0274] The relaxing massage may be a massage according to a preset massage intensity and speed. For example, the relaxing massage may be provided as an average massage intensity and an average massage speed among the massage intensity and speed that the massage device 1000 may provide, or as a minimum massage intensity and a minimum massage speed, but is not limited thereto.

[0275] Through this, the control part 1400 can prevent injuries caused by the stretching mode by relaxing the user's body before providing the stretching mode, and increase the stretching effect.

[0276] As described above, the control unit 1400 provides the stretch mode to the user after the massage device 1000 reclines and provides a relaxing massage, but is not limited thereto. For example, the control unit 1400 may provide the stretch mode while performing at least one of the actions of reclining the massage device 1000 and providing a relaxing massage.

[0277] Fig.24 FIG. 1 is a diagram showing a body airbag and a leg airbag included in a body massage part according to an embodiment of the present invention.

[0278] The body massage part 1000 may include a body air bag 1600 for massaging (or pressurizing) the user's body.

The second shoulder airbag 1631 can be arranged in an area corresponding to the other side of the user's shoulder (e.g., an upper end area on the other side of the body massage part 1000) in the entire area on the other side of the body massage part 1000 and massage the other side of the user's shoulder. At this time, the first shoulder airbag 1611 and the second shoulder airbag 1631 can massage (or fix) the user's shoulders by pressurizing the surfaces on both sides of the user's shoulders (or the upper surfaces on both sides of the shoulders).

[0283] The first back airbag 1613 may be arranged in an area corresponding to one side of the user's back (e.g., an area between an upper end of one side and a lower end of one side of the body massage part 1000) in the entire area of ​​one side of the body massage part 1000 and massage one side of the user's back. The second back airbag 1633 may be arranged in an area corresponding to the other side of the user's back (e.g., an area between an upper end of the other side and a lower end of the other side of the body massage part 1000) in the entire area of ​​the other side of the body massage part 1000 and massage the other side of the user's back. At this time, the first back airbag 1613 and the second back airbag 1633 massage the user's back by applying pressure to the rear surface of the user's back, thereby pushing (or moving) the user's back toward the front direction of the body massage part 1000.

[0284] The first pelvic airbag 1615 can be arranged in the entire area of ​​one side of the body massage part 1000 in an area corresponding to one side of the user's pelvis (for example, the lower end area of ​​one side of the body massage part 1000) and massage one side of the user's pelvis. The second pelvic airbag 1635 can be arranged in the entire area of ​​the other side of the body massage part 1000 in an area corresponding to the other side of the user's pelvis (for example, the lower end area of ​​the other side of the body massage part 1000) and massage the other side of the user's pelvis. At this time, the first pelvic airbag 1615 and the second pelvic airbag 1635 can pressurize the surfaces on both sides of the user's pelvis to massage (or fix) the user's pelvis.

[0285] The first thigh airbag 1617 can be arranged in the entire area of ​​one side of the body massage part 1000, in an area corresponding to the thigh of one leg of the user (or the central area of ​​the lower end central area of ​​the body massage part 1000), and massage the thigh of one leg of the user. The second thigh airbag 1637 can be arranged in the entire area of ​​the other side of the body massage part 1000, in an area corresponding to the thigh of the other leg of the user (or the central area of ​​the lower end central area of ​​the body massage part 1000), and massage the thigh of the other leg of the user. At this time, the first thigh airbag 1617 and the second thigh airbag 1637 can massage in a manner of pressurizing the rear surface of the thigh of the user and pushing the two thighs of the user toward the upper side of the body massage part 1000.

[0286] The third body airbag 1650 is arranged in an area corresponding to the user's perineum (e.g., the front center area of ​​the body massage part 1000) in the entire area between one side and the other side of the body massage part 1000, and massages the user's perineum. At this time, the perineum airbag as the third body airbag 1650 pressurizes the user's perineum in a manner of pushing / lifting the user toward the upper side of the body massage part 1000 to massage the user's body.

[0287] Also, the leg massaging part 2000 may include a leg airbag 1700 for massaging the user's legs.

[0288] For example, the leg airbag 1700 may include a first leg airbag 1710 corresponding to the first leg massage part 2000a (or the user's leg on one side) and a second leg airbag 1730 corresponding to the second leg massage part 2000b (or the user's leg on the other side). At this time, each leg airbag 1710, 1730 can massage the user's leg by expanding and contracting.

[0289] Specifically, the first leg massage part 2000a may include a first leg airbag 1710 disposed at at least a portion of the first leg massage part 2000a. The second leg massage part 2000b may include a second leg airbag 1730 disposed at at least a portion of the second leg massage part 2000b.

[0290] Each leg airbag 1710, 1730 may include at least one of a calf airbag disposed at a position corresponding to a user's calf and a foot airbag disposed at a position corresponding to a user's foot.

[0291] For example, first leg airbag 1710 may include at least one of first calf airbag 1711 and second foot airbag 1713. Second leg airbag 1730 may include at least one of second calf airbag 1731 and second foot airbag 1733.

[0292] The first calf airbag 1711 may be disposed in an area of ​​the first leg massaging part 2000a corresponding to the calf of one leg of the user (eg, an upper end area of ​​the first leg massaging part 2000a) and massage the calf of the user.

[0293] For example, the first calf airbag 1711 may include at least one of the first sub-calf airbag 1711a and the second sub-calf airbag 1711b. The first sub-calf airbag 1711a may be arranged in an area corresponding to the side of the calf of one leg and massage (or pressurize) the side of the calf. The second sub-calf airbag 1711b may be arranged in an area corresponding to the back of the calf of one leg and massage the back of the calf. At this time, the first sub-calf airbag 1711a can massage (or fix) the user's calf by pressurizing both sides of the calf of one leg.

[0294] The second calf airbag 1731 may include at least one of a third sub-calf airbag 1731a and a fourth sub-calf airbag 1731b. The third sub-calf airbag 1731a is the same as the first sub-calf airbag 1711a applied to the second leg massage part 2000b, so its detailed description will be omitted. The fourth sub-calf airbag 1731b is the same as the second sub-calf airbag 1711b applied to the second leg massage part 2000b, so its detailed description will be omitted.

[0295] The first foot airbag 1713 may be disposed in an area corresponding to the foot of one leg of the user (eg, a lower end area of ​​the first leg massage part 2000a) in the entire area of ​​the second leg massage part 2000a to massage the foot of the user.

[0296] For example, the first foot airbag 1713 may include at least one of the first sub-foot airbag 1713a and the second sub-foot airbag 1713b. The first sub-foot airbag 1713a may be arranged in an area corresponding to the side of the foot (or foot, etc.) of one leg and massage (or pressurize) the side of the foot (or foot, etc.). The second sub-foot airbag 1713b may be arranged in an area corresponding to the back of the foot (or heel, Achilles tendon) of one leg and massage (or pressurize) the back of the foot (or heel, Achilles tendon). At this time, the first sub-foot airbag 1713a can massage (or fix) the user's foot by pressurizing both sides of the foot of one leg.

[0297] The second foot airbag 1733 may include at least one of a third sub-foot airbag 1733a and a fourth sub-foot airbag 1733b. The third sub-foot airbag 1733a is the same as the first sub-foot airbag 1713a applied to the second leg massage part 2000b, so its detailed description will be omitted. The fourth sub-foot airbag 1733b is the same as the second sub-foot airbag 1713b applied to the second leg massage part 2000b, so its detailed description will be omitted.

[0298] Fig.25 A sequence diagram for illustrating a hamstring stretching mode according to an embodiment of the present invention is shown.

[0299] Reference Fig.25 , the control unit 1400 controls the action of the massage device 1000 based on the massage map of the hamstring stretching mode (or the hamstring relaxation mode), so that the hamstring stretching mode can be provided to the user.

[0300] The hamstring stretching mode may include a leg stretching action for stretching the user's leg (or the hamstring of the leg). Through this, the control unit 1400 stretches the user's leg through the leg stretching action to relax the user's hamstring (or hamstring muscle), thereby preventing shortening and injury of the hamstring.

[0301] First, the control unit 1400 may cause the massage device 1000 to recline (step S2510). Since the operation in step S2510 is the same as the operation in step S2210, a detailed description thereof will be omitted.

[0302] Thereafter, the control part 1400 controls the first leg massage part 2000a and the second leg massage part 2000b to perform a leg stretching action for stretching the user's legs through the leg length adjustment module 2500 and the leg angle adjustment module 1350 in a state where the massage device 1000 is reclining (step S2530).

[0303] For example, the control unit 1400 may perform the leg stretching action by controlling at least one of the first length of the first leg massage unit 2000a, the first angle of the first leg massage unit 2000a, the second length of the second leg massage unit 2000b, and the second angle of the second leg massage unit 2000b. When adjusting at least one parameter among the first length, the second length, the first angle, and the second angle, the control unit 1400 may adjust at least one parameter while inflating the leg airbag corresponding to at least one airbag parameter of the first leg airbag 1710 and the second leg airbag 1730.

[0304] The leg stretching action may include at least one of a first leg stretching action, a second leg stretching action, and a third leg stretching action. The first leg stretching action may be an action of stretching the hamstrings of one leg by stretching one leg of the user. The second leg stretching action may be an action of stretching the hamstrings of the other leg by stretching the other leg of the user. The third leg stretching action may be an action of stretching the hamstrings of the user's legs by stretching both the one leg and the other leg of the user at the same time.

[0305] For example, the control unit 1400 may first perform at least one of the first leg stretching action and the second leg stretching action, and may perform the third leg stretching action after performing the remaining leg stretching actions later. At this time, the control unit 1400 may repeatedly perform the first leg stretching action and the second leg stretching action, and then perform the third leg stretching action. For example, the control unit 1400 may repeatedly perform the first leg stretching action and the second leg stretching action based on a preset number of repetitions. At this time, the number of repetitions may be preset according to a variety of objects and stored in the memory 1430.

[0306] As described above, after the control unit 1400 repeatedly performs the first leg stretching action and the second leg stretching action, the third leg stretching action is performed, but not limited thereto. The control unit 1400 can randomly perform the first leg stretching action, the second leg stretching action, and the third leg stretching action in various ways and combinations.

[0307] Hereinafter, for convenience of explanation, it will be assumed that the control section 1400 sequentially performs the first leg stretching motion, the second leg stretching motion, and the third leg stretching motion.

[0308] Fig.26 Shown for illustration Fig.25 The sequence diagram of the leg stretching action shown is as follows, Fig. 27 It is used to illustrate Fig.26 Diagram of each leg stretch shown.

[0309] Reference Fig.26 and Fig. 27 After executing the first leg stretching action (step S2531), the control unit 1400 executes the second leg stretching action (step S2533), and finally may execute the third leg stretching action (step S2535).

[0310] When each leg stretching action is completed, the control unit 1400 can restore the state of each leg massage unit to the state before performing each leg stretching action. At this time, the state of each leg massage unit may refer to the length and angle of each leg massage unit, the action state of each leg airbag, the action state of each foot massage module, etc. Fig. 27The motion A shown, the state before performing each leg stretching action may refer to a state where the massage device 1000 is reclining.

[0311] First, the control unit 1400 is in a state where the massage device 1000 is reclining (such as action A), as shown in FIG. Fig. 27 The action B shown is to perform a first leg stretching action of lifting only one side of the user's leg to stretch one side of the user's leg (step S2531).

[0312] For example, the control unit 1400 adjusts the first length and / or the first angle of the first leg massage part 2000a through at least one of the first leg angle adjustment module 1350a and the first leg length adjustment module 2500a, so that the first leg stretching action can be performed. After completing the first leg stretching action, the control unit 1400 can restore the state of each leg massage part.

[0313] Through this, the control unit 1400 quickly and accurately extends and relaxes the hamstring of one leg of the user by stretching one leg of the user.

[0314] Then, if Fig. 27 In the action C shown, the control unit 1400 may stretch the other leg of the user by performing a second leg stretching action of only lifting the other leg of the user (step S2533).

[0315] For example, the control unit 1400 can adjust the second length and / or the second angle of the second leg massage part 2000b to perform the second leg stretching action through at least one of the second leg angle adjustment module 1350b and the second leg length adjustment module 2500b. After completing the second leg stretching action, the control unit 1400 can restore the state of each leg massage part.

[0316] Through this, the control unit 1400 can quickly and accurately stretch and relax the hamstrings of the other leg of the user by stretching the other leg of the user. In addition, the control unit 1400 can evenly stretch (or repeatedly stretch) the legs of the user on both sides through the first leg stretching action and the second leg stretching action, so that the hamstrings of the user on both sides can be evenly and fully stretched and relaxed.

[0317] Finally, if Fig. 27In the action D shown, the control unit 1400 can stretch the legs of the user on both sides by performing a third leg stretching action of lifting one leg and the other leg of the user at the same time (step S2535). At this time, the third leg stretching action can include at least one of an alignment stretching action in which the first leg massage part 2000a and the second leg massage part 2000b are aligned and move in parallel, and a cross stretching action in which the first leg massage part 2000a and the second leg massage part 2000b are crossed and move.

[0318] For example, the control unit 1400 can adjust the first length, the second length, the first angle and / or the second angle through at least one of each leg angle adjustment module and each leg length adjustment module, so that the third leg stretching action can be performed. The control unit 1400 can restore the state of each leg massage part after completing the third leg stretching action.

[0319] Through this, the control part 1400 quickly and accurately lengthens and relaxes the hamstrings of both legs of the user by stretching both legs of the user.

[0320] Furthermore, at the time point when the third leg stretching action is completed, the control unit 1400 may perform a buttocks massage for massaging the user's buttocks through the massage module 1110, thereby stretching the user's legs and buttocks at the same time.

[0321] For example, at the time point when the third leg stretching action is completed, the control unit 1400 can provide massage to the user's buttocks through the massage module 1110. At this time, the control unit 1400 can make the massage module 1110 protrude in the front direction of the massage module 1110 to provide the user with acupressure massage of the user's buttocks. At this time, the front direction of the massage module 1110 can be the direction in which the massage module 1110 approaches the user's body, which is the direction from the rear of the massage module 1110 to the front of the massage module 1110.

[0322] As described above, the control unit 1400 provides acupressure massage as buttocks massage, but is not limited thereto. For example, buttocks massage may include at least one of acupressure massage, kneading massage, beating massage, and compound massage. Compound massage may be a combination of two or more of acupressure massage, kneading massage, and beating massage.

[0323] By this, the control unit 1400 stretches the user's legs on both sides while stretching the user's buttocks to assist the stretching of the user's legs on both sides, thereby being able to quickly and accurately lengthen and relax the hamstrings on both sides of the user's legs compared to not stretching the user's buttocks.

[0324] Below, each leg stretching exercise is explained in detail.

[0325] Fig.28It is used to illustrate Fig. 27 Figure 1 of the first leg stretch shown.

[0326] First, the control unit 1400 may adjust the first angle of the first leg massaging part 2000a through the first leg angle adjusting module 1350a, thereby stretching one leg of the user (action B1).

[0327] For example, the control part 1400 may adjust the first angle while increasing the first length of the first leg massage part 2000a (or while increasing the first length) through the first leg length adjustment module 2500a while maintaining the second length of the second leg massage part 2000b.

[0328] When adjusting the first length, the control unit 1400 can increase the first length based on the length of the user's leg, so as to stretch the user's leg. At this time, the control unit 1400 moves the first leg massage part 2000a toward the lower side of the first leg massage part 2000a through the first leg length adjustment module 2500a, so as to increase the first length.

[0329] For example, the control unit 1400 may determine the adjustment length for adjusting the first length based on the length of one leg. The control unit 1400 may adjust the first length based on the adjustment length. At this time, the control unit 1400 may increase the first length by moving the first leg massage part 2000a to the adjustment length or to a position corresponding to the adjustment length.

[0330] The above-mentioned method for determining the adjustment length may be as follows. For example, the memory 1430 may include a leg length table, which includes multiple leg lengths and an adjustment length matched with each leg length. The leg length table may be preset by a variety of objects and stored in the memory 1430. The controller 1400 may extract an adjustment length that matches any one of the multiple leg lengths in the leg length table based on the length of one leg of the user. At this time, any one leg length may be equal to or similar to the length of one leg of the user. A similar length may refer to a length within a preset error range compared to the length of one leg. The control unit 1400 may determine the extracted adjustment length as the adjustment length for adjusting the first length.

[0331] When adjusting the first angle, the control unit 1400 tilts the first leg massage unit 2000a upward by a preset angle through the first leg angle adjustment module 1350a to adjust the first angle, so that the user's leg can be stretched. At this time, the control unit 1400 can tilt the body massage unit 1100 toward the rear direction of the body massage unit 1100 by a preset angle while adjusting the first angle to make the body massage unit 1100 recline.

[0332] For example, the control unit 1400 may tilt the first leg massage unit 2000a upward to the maximum extent toward the upper part of the massage device 1000. At this time, the control unit 1400 may inflate the airbag of the second arm massage unit 1230 while adjusting the first angle to assist in stretching the user's leg so as to safely lift the user's leg. When the action B1 is finished, the airbag of the second arm massage unit 1230 may be deflated.

[0333] In the case of adjusting the first angle, the control part 1400 may adjust the first angle while maintaining (action B1a) or adjusting (action B1b) the second angle of the second leg massage part 2000b. In other words, the control part 1400 adjusts the first angle while fixing the second leg massage part 2000b, or may adjust the first angle and the second angle by tilting the first leg massage part 2000a and the second leg massage part 2000b in opposite directions (or tilting in different directions from each other). Hereinafter, for the sake of convenience of explanation, it is assumed that the second angle is adjusted.

[0334] When adjusting the second angle, the control unit 1400 may adjust the second angle by tilting the second leg massage unit 2000b downward through the second leg angle adjustment module 1350b while adjusting the first angle, thereby assisting in stretching one leg of the user.

[0335] For example, the control unit 1400 may adjust the second angle based on the length of the other leg of the user. Specifically, the control unit 1400 may adjust the adjustment angle for adjusting the second angle based on the length of the other leg. The control unit 1400 may adjust the second angle based on the adjustment angle. At this time, the control unit 1400 may adjust the second angle by tilting the second leg massage unit 2000b to the adjustment angle or tilting it to a position corresponding to the adjustment angle.

[0336] The above method for determining the adjustment angle may be similar to the method for determining the adjustment length. For example, the memory 1430 may include a leg angle table, which includes multiple leg lengths and adjustment angles matching each leg length. The leg angle table may be preset by a variety of objects and stored in the memory 1430. The control unit 1400 extracts the adjustment angle matching any one of the multiple leg lengths pre-stored in the memory 1430 based on the length of the other leg of the user. At this time, any one leg length may be equal to or similar to the length of the other leg of the user. Similar length may refer to a length within a preset error range compared to the length of the other leg. The control unit 1400 may determine the extracted adjustment angle as the adjustment angle for adjusting the second angle.

[0337] As described above, the second angle is adjusted based on the adjustment angle, but is not limited thereto. For example, similar to the first angle adjustment action, the control part 1400 may make the second leg massage part 2000b tilt downwardly to the maximum extent toward the lower part of the massage device 1000.

[0338] When the action B1 is performed, the control unit 1400 may adjust the first length, the first angle, and the second angle while inflating at least one of the first leg airbag 1710 and the second leg airbag 1730 while maintaining the second length.

[0339] For example, the control unit 1400 may adjust the first length and the first angle while inflating the first leg airbag 1710. At this time, when the first calf airbag 1711 is not inflated, the control unit 1400 may inflate only the first foot airbag 1713.

[0340] In other words, the control unit 1400 can accurately pull the user's leg on one side by adjusting the first length and the first angle while fixing the user's leg on one side (or the foot of the user's leg on one side) through the first leg airbag 1710. Through this, the control unit 1400 can improve the stretching effect of the leg to be stretched by accurately pulling the leg to be stretched, i.e., the user's leg on one side, and fully extending and stretching it.

[0341] The control unit 1400 may adjust the second angle while not expanding the second leg airbag 1730 or expanding the second leg airbag 1730. At this time, the control unit 1400 may expand only the second foot airbag 1733 while the second calf airbag 1731 is not expanded.

[0342] In other words, the control unit 1400 can assist the stretching of one leg of the user by adjusting the second angle while the other leg of the user is not fixed or is fixed by the second leg airbag 1730. When the other leg is fixed, the stretching of one leg can be more accurately assisted compared to the case where the other leg is not fixed.

[0343] Hereinafter, for convenience of explanation, it will be assumed that the control portion 1400 adjusts the first length, the first angle, and the second angle while inflating both the first leg airbag 1710 and the second leg airbag 1730 .

[0344] When the action B1 is performed, the control unit 1400 may inflate at least one of the thigh airbag and the pelvic airbag. At this time, the thigh airbag can be used for stretching, and the pelvic airbag can be used for posture fixation.

[0345] As an example, the control unit 1400 can adjust the first length, the first angle, and the second angle while inflating the first thigh airbag 1617 and the second thigh airbag 1637. At this time, the first thigh airbag 1617 and the second thigh airbag 1637 can be inflated simultaneously with the first leg airbag 1710 and the second leg airbag 1730. Through this, the control unit 1400 can stretch the leg of the user on one side by inflating the first thigh airbag 1617 and the second thigh airbag 1637 while moving the lower body of the user to the upper side, thereby improving the stretching effect of the leg on one side of the user.

[0346] As another example, the control unit 1400 can adjust the first length, the first angle, and the second angle while inflating the first pelvic airbag 1615 and the second pelvic airbag 1635. At this time, the first pelvic airbag 1615 and the second pelvic airbag 1635 can be inflated simultaneously with the first leg airbag 1710 and the second leg airbag 1730. Through this, the control unit 1400 can stretch one side of the user's leg while fixing the user's lower body by inflating the first pelvic airbag 1615 and the second pelvic airbag 1635, thereby accurately and safely stretching one side of the user's leg.

[0347] As another example, the control unit 1400 can adjust the first length, the first angle, and the second angle while simultaneously inflating the first thigh airbag 1617 and the second thigh airbag 1637 and the first pelvic airbag 1615 and the second pelvic airbag 1635. The actions of inflating the first thigh airbag 1617 and the second thigh airbag 1637 and the actions of inflating the first pelvic airbag 1615 and the second pelvic airbag 1635 are the same as those described above, so detailed descriptions thereof will be omitted.

[0348] Thereafter, the control unit 1400 may maintain the stretching of one leg of the user by maintaining the adjusted first angle for a preset time (action B2).

[0349] The control unit 1400 stops the operation of the first leg angle adjustment module 1350a and the second leg angle adjustment module 1350b, and keeps the adjusted first angle and second angle for a preset time by keeping the first leg angle adjustment module 1350a and the second leg angle adjustment module 1350b in the stopped state (action B2b). At this time, the preset time can be preset by various objects and stored in the memory 1430.

[0350] As described above, when maintaining the second angle, the control unit 1400 maintains the adjusted first angle and the maintained second angle for a preset time (action B2a) by stopping the first leg angle adjustment module 1350a and keeping the first leg angle adjustment module 1350a and the second leg angle adjustment module 1350b stopped.

[0351] Through this, the control unit 1400 can maintain the stretching of the leg on one side by maintaining the adjusted first angle, and assist the stretching of the leg on one side by maintaining the adjusted second angle.

[0352] In the process of maintaining the adjusted first angle and the second angle, the control unit 1400 can adjust both the first length and the second length. For example, the control unit 1400 can increase the first length adjusted when the action B1 is performed by a preset length, while reducing the maintained second length to a minimum length. At this time, once the action B1 is completed (or while maintaining the adjusted first angle and the second angle), the control unit 1400 can adjust both the first length and the second length while shrinking the second leg airbag 1730. The control unit 1400 can expand the first calf airbag 1711 while shrinking the second leg airbag 1730.

[0353] In the process of maintaining the adjusted first angle and second angle, the control unit 1400 further stretches the user's leg by driving the first foot massage unit 2610. At this time, the control unit 1400 may not drive (or stop) the second foot massage unit 2630.

[0354] For example, the control unit 1400 can keep the first foot massage unit 2610 in a driven state while adjusting the first length and the second length, while maintaining the first angle and the second angle by driving the first foot massage unit 2610. Thus, the control unit 1400 can massage the foot of one leg of the user through the first foot massage unit 2610, thereby improving the stretching effect of the hamstring of one leg.

[0355] In the process of maintaining the adjusted first angle and second angle, the control unit 1400 can further stretch the user's leg by repeating the expansion and contraction of the first leg airbag 1710. At this time, the control unit 1400 can repeat the action of increasing the first length by a preset length without expanding the second leg airbag 1730. The control unit 1400 can increase the first length while contracting the first leg airbag 1710.

[0356] For example, in the process of maintaining the adjusted first angle and second angle, the control unit 1400 can stretch one side of the user's leg by repeating the expansion and contraction of the first leg airbag 1710. At this time, the control unit 1400 can repeat the expansion and contraction of both the first sub-calf airbag 1711a and the second sub-calf airbag 1711b and the second sub-foot airbag 1713b. The control unit 1400 can make the first sub-foot airbag 1713a not expand.

[0357] The control unit 1400 may repeat the expansion and contraction of the thigh airbags during the process of repeating the expansion and contraction of the first leg airbag 1710. For example, the control unit 1400 may link the expansion action of the first leg airbag 1710 with the expansion action of the first thigh airbag 1617 and the second thigh airbag 1637. The control unit 1400 may link the contraction action of the first leg airbag 1710 with the contraction action of the first thigh airbag 1617 and the second thigh airbag 1637.

[0358] Fig.29 It is used to illustrate Fig. 27 Figure 2 of the second leg stretch shown.

[0359] While maintaining the first length, the control unit 1400 can increase the second length while adjusting the second angle through the second leg angle adjustment module 1350a (action C1), and stretch the user's other leg (action C) by maintaining the adjusted second angle for a preset time (action C2).

[0360] The action of action C is performed inversely to the action of action B, so detailed description will be omitted. For example, the action of the first leg massage part 2000a in the action of action C may be the same as the action of the second leg massage part 2000b in the action of action B. The action of the second leg massage part 2000b in the action of action C may be the same as the action of the first leg massage part 2000a in the action of action B.

[0361] The first leg massage part 2000a can have a variety of actions, such as the first length and angle adjustment action, the action of the first leg airbag 1710, the action of the thigh and pelvis airbags linked when the first foot massage part 2610 and the first leg massage part 2000a are in action, etc. The second leg massage part 2000b can have a variety of actions, such as the second length and angle adjustment action, the action of the second leg airbag 1730, the action of the thigh and pelvis airbags linked when the second foot massage part 2630 and the second leg massage part 2000b are in action, etc.

[0362] Fig.30 It is used to illustrate Fig. 27 Figure 3 of the leg stretch shown.

[0363] After performing the alignment stretching action (actions D1 and D2 ), the control unit 1400 performs a cross stretching action (action D3 ) to stretch both sides of the user's legs (action D).

[0364] First, the control unit 1400 can stretch the legs of the user on both sides by adjusting the first angle and the second angle in the same manner when increasing the first length and the second length (or while increasing the first length and the second length) (action D1). At this time, the control unit 1400 can adjust the first angle and the second angle in the same manner by tilting the first leg massage part 2000a and the second leg massage part 2000b upward in the same manner.

[0365] The movement of the first leg massage part 2000a in the movement D1 may be the same as the movement of the first leg massage part 2000a in the movement B1. The movement of the second leg massage part 2000b in the movement D1 may be the same as the movement of the second leg massage part 2000b in the movement B1.

[0366] Thereafter, the control part 1400 may maintain the adjusted first angle and second angle for a preset time in the same manner as each other (action D2). The action of the first leg massage part 2000a in the action of action D2 may be the same as the action of the first leg massage part 2000a in the action of action B2. The action of the second leg massage part 2000b in the action of action D2 may be the same as the action of the second leg massage part 2000b in the action of action B2.

[0367] Finally, the control unit 1400 may perform a cross-stretching action (action D3 ).

[0368] For example, the control unit 1400 can adjust the adjusted first length and second length in opposite ways while re-adjusting the first angle and second angle adjusted in the same way as each other. At this time, the control unit 1400 can adjust the first angle and second angle and the first length and second length while maintaining the expansion of the first foot airbag 1713, the second foot airbag 1733, the thigh and pelvic airbags and contracting the first calf airbag 1711 and the second calf airbag 1731.

[0369] In case of re-adjusting the first angle and the second angle, the control part 1400 may perform the first cross stretching action of tilting the first leg massaging part 2000a and the second leg massaging part 2000b downward in the same manner as each other.

[0370] When the first length and the second length are adjusted, the control unit 1400 may repeatedly perform a second cross-stretching action of increasing the first length but decreasing the second length and a third cross-stretching action of decreasing the first length but increasing the second length.

[0371] In other words, the control unit 1400 repeatedly performs the second and third cross-stretching actions while performing the first cross-stretching action, but is not limited thereto. For example, the control unit 1400 may repeatedly perform the second and third cross-stretching actions after performing the first cross-stretching action, or may repeatedly perform the second and third cross-stretching actions before performing the first cross-stretching action.

[0372] The above-mentioned technical concept of the present invention is described in conjunction with the accompanying drawings, but this is only an exemplary description of the preferred embodiment of the present invention and does not limit the present invention. In addition, those skilled in the art of the present invention should understand that various modifications and imitations can be made without departing from the technical concept of the present invention.

[0373] In addition, the structure and function of the massage device of this specification can be extended and applied to various (wearable) health care devices that can provide health care functions (e.g., massage function, biosignal measurement function, etc.). Therefore, the "massage device" in this specification can be replaced with "(wearable) health care device" for description.
