[0131] Reference Figure 1 According to one embodiment of the present invention, a massage device 1000 may include a massage section forming an area for accommodating at least a portion of a user's body, supporting the user's body (e.g., torso), and massaging a portion of the user's body.

[0132] The massage unit may include at least one of the following massage units: a body massage unit 1100 for massaging at least a part of the user's body; an arm massage unit 1200 for massaging the user's arms; and a leg massage unit 1300 for massaging the user's legs.

[0133] The body massage unit 1100 can massage at least a part of the user's body. For example, the body massage unit 1100 can massage at least a part of at least one of the user's upper body and lower body.

[0134] Specifically, the body massage unit 1100 may include: a massage module 1110 for providing massage function to at least a part of the user's body; an audio output module 1120 for providing audio output to the user in any form; a main frame 1130 for forming the frame of the body massage unit 1100 and supporting the user's body; and a user input unit 1140 for receiving input in any form from the user.

[0135] The structures of the body massage unit 1100 described above are merely exemplary embodiments. In addition to the aforementioned structures, the body massage unit 1100 may also include various other structures.

[0136] In addition, such as Figure 1 The shape and structure of the massage device 1000 shown are merely examples. Various forms of massage devices 1000 should also fall within the scope of this utility model without departing from the scope defined by the claims.

[0137] The body massage unit 1100 can be formed into a space of any shape to accommodate a user. The body massage unit 1100 can have a space that corresponds to the shape of the user's body. For example, as... Figure 1 As shown, the body massage unit 1100 can be implemented in a seated form that can accommodate the entire body or part of the user's body, thereby supporting at least a part of the user's body. For example, the body massage unit 1100 may include: a backrest for supporting at least a part of the user's upper body; and a seat (not shown in the figures for ease of explanation) for supporting at least a part of the user's lower body.

[0138] The part of the body massage unit 1100 that contacts the ground may include any material or component for enhancing friction (e.g., anti-slip mat, etc.), and may include wheels (not shown in the figures for ease of explanation) for enhancing the mobility of the massage device 1000.

[0139] At least a portion of the body massage unit 1100 is capable of sliding. For example, when the body massage unit 1100 begins to massage (or when the body massage unit 1100 is actuated), at least a portion of the body massage unit 1100 can slide forward. Additionally, the body massage unit 1100 can tilt backward. As a result, the body massage unit 1100 can provide massage in a rearward tilted state. For example, the massage device 1000 may include an actuator (not shown in the figures for ease of explanation) for tilting the massage device 1000 (or body massage unit 1100) in a rearward direction. The massage device 1000 can tilt or return the body massage unit 1100 to its original state by actuating the aforementioned actuator. In this case, the actuator may be disposed in at least a portion of the massage device (e.g., the base frame).

[0140] According to one embodiment of the present invention, the massage device 1000 may include at least one airbag (not shown in the drawings for ease of explanation). The airbag may be located in at least a portion of the body massage portion 1100 (e.g., at least one of the areas corresponding to the user's shoulder, the pelvis, and the waist in the entire area of ​​the body massage portion 1100), at least a portion of the arm massage portion 1200, and at least a portion of the leg massage portion 1300, but is not limited thereto, and may be disposed in multiple portions of the massage device 1000.

[0141] The massage device 1000 may include an air supply unit capable of inflating an airbag by supplying air to it. The air supply unit may be located inside the body massage unit 1100 or in the leg massage unit 1300. Alternatively, the air supply unit may be located outside the massage device 1000.

[0142] The leg massage unit 1300 may be disposed at the lower part of the body massage unit 1100 and / or at the lower front part of the massage device 1000. The leg massage unit 1300 may include at least one of the following leg massage units: a first leg massage unit 1310 disposed on one side of the leg massage unit 1300 for massaging one side of the user's leg; and a second leg massage unit 1330 disposed on the other side of the leg massage unit 1300 for massaging the other side of the user's leg.

[0143] The leg massage unit 1300 includes a receiving space for accommodating a user's legs and can provide leg massage to the user by massaging at least a portion of the user's legs. For example, the leg massage unit 1300 may include a calf massage unit for massaging the user's lower legs and / or a foot massage unit for massaging the user's feet.

[0144] The leg massage unit 1300 can be adjusted in length according to the user's body characteristics. For example, when a tall user uses the massage device 1000, the leg massage unit 1300 needs to be lengthened because the user's calves are long. Conversely, when a short user uses the massage device 1000, the leg massage unit 1300 needs to be shortened because the user's calves are short. Therefore, the leg massage unit 1300 can provide leg massage customized for the user's height. According to one embodiment of this utility model, the user can control the massage device 1000 using a massage device control device CD. The massage device control device CD can be connected to the massage device 1000 via wired and / or wireless communication.

[0145] The massage device control device CD may include at least one of the following user devices: remote controller, cellular phone, personal digital assistant (PDA), but is not limited thereto, and may include various electronic devices that can be connected to the massage device 1000 via wired or wireless communication.

[0181] Figure 5 This is a diagram illustrating the individual rotation of the leg massage section in a massage device according to an embodiment of the present invention.

[0182] Reference Figure 5 The leg massage unit 1300 can be configured to correspond to both sides of the user's legs. For example, the leg massage unit 1300 may include: a first leg massage unit 1310, corresponding to one side of the user's leg; and a second leg massage unit 1330, corresponding to the other side of the user's leg.

[0183] The first leg massage unit 1310 and the second leg massage unit 1330 can be controlled independently. For example, the first leg massage unit 1310 and the second leg massage unit 1330 can provide massage functions to the user independently. Furthermore, the first leg massage unit 1310 and the second leg massage unit 1330 can rotate independently. Different massages or alternating massages can be provided to the user's two legs as needed. Additionally, stretching or massage can be provided to the user's two legs based on rotation. In this case, the first leg massage unit 1310 and the second leg massage unit 1330 can rotate simultaneously or rotate the user's two legs individually. In other words, the first leg massage unit 1310 and the second leg massage unit 1330 can be driven independently of each other.

[0184] Figure 6 is used for illustration. Figure 5 A diagram illustrating the principle of leg massager rotation. Specifically, Figure 6A It is used for explanation Figure 5 The image shows the leg massage section and the leg angle adjustment module 1350. Figure 6B It is used for explanation Figure 6A The image shows the leg angle adjustment module 1350.

[0185] Reference Figure 6A and Figure 6B The massage device 1000 may include a leg angle adjustment module 1350 for rotating the leg massage unit 1300. The leg angle adjustment module 1350 may be configured inside the body massage unit 1100. For example, the leg angle adjustment module may be connected to the main frame 1130.

[0186] The leg angle adjustment module 1350 can be driven to extend in one direction. The leg massage unit 1300 can rotate as the leg angle adjustment module 1350 extends.

[0187] The leg angle adjustment module 1350 may include a linkage member 1351 at one end. The linkage member 1351 can provide rotational power to the leg massage unit 1300 by contacting it. A wheel 1351a may be provided at the end of the linkage member 1351 on the leg massage unit 1300 side.

[0188] The leg angle adjustment module 1350 can be configured to correspond to the first leg massage unit 1310 and the second leg massage unit 1330 respectively. The two leg angle adjustment modules 1350 are respectively connected to the first leg massage unit 1310 and the second leg massage unit 1330, so that the first leg massage unit 1310 and the second leg massage unit 1330 can rotate independently.

[0189] For example, the leg angle adjustment module 1350 may include a first leg angle adjustment module 1350a and a second leg angle adjustment module 1350b.

[0190] The first leg angle adjustment module 1350a can be configured in the area (or position) of the massage device 1000 corresponding to the first leg massage 1310. For example, the first leg angle adjustment module 1350a can be configured on the lower side of the body massage unit 1100 and / or behind the first leg massage unit 1310.

[0191] The first leg angle adjustment module 1350a can adjust the angle of the first leg massage unit 1310 by tilting (or rotating) it in at least one of the clockwise and counterclockwise directions. For example, the first leg angle adjustment module 1350a can be an actuator capable of changing its length. The first leg angle adjustment module 1350a can tilt the first leg massage unit 1310 by pushing or pulling its rearward position by changing its length.

[0192] The second leg angle adjustment module 1350b can be configured in the area (or position) of the massage device 1000 corresponding to the second leg massage unit 1330. For example, the second leg angle adjustment module 1350b can be configured on the lower side of the body massage unit 1100 and / or behind the second leg massage unit 1330.

[0193] The second leg angle adjustment module 1350b can adjust the angle of the second leg massage unit 1330 by tilting (or rotating) it in at least one of the clockwise and counterclockwise directions. For example, the second leg angle adjustment module 1350b can be an actuator capable of changing its length. The second leg angle adjustment module 1350b can tilt the second leg massage unit 1330 by pushing or pulling its rearward position by changing its length.

[0194] Figure 7 This is a diagram showing the state in which the leg massage part of an embodiment of the present invention is connected to the leg connecting frame.

[0195] Reference Figure 7 The leg massage unit 1300 can be rotatably connected to the leg connecting frame 1131b. For example, the leg connecting frame 1131b is disposed at one end (or lower end) of the body massage unit 1100, and the first leg massage unit 1310 and the second leg massage unit 1330 can be connected in a manner that allows them to rotate relative to the leg connecting frame 1131b.

[0196] The upper frame 1131 may include a leg connecting frame 1131b. The leg connecting frame 1131b may be disposed at the front end of the upper frame 1131. The leg connecting frame 1131b may be manufactured as a separate component and attached to the upper frame 1131, or it may be manufactured integrally with the upper frame 1131. When the leg connecting frame 1131b is manufactured integrally with the upper frame 1131, the leg connecting frame 1131b may refer to a constituent element of the upper frame 1131.

[0197] A central support bracket 1530 and a side support bracket 1550 can be connected to the leg connection frame 1131b. For example, the central support bracket 1530 and the side support bracket 1550 can be welded to the leg connection frame 1131b, or they can be joined by fastening members such as bolts or rivets. However, the method of joining the central support bracket 1530 and the side support bracket 1550 to the leg connection frame 1131b can be replaced by various methods commonly used in the technical field to which this invention pertains.

[0198] The central support bracket 1530 and the side support bracket 1550 can rotatably fix the leg massage unit 1300.

[0199] The first leg massage unit 1310 and the second leg massage unit 1330 can be disposed in front of the leg connecting frame 1131b. For example, the first leg massage unit 1310 can be disposed in front of the leg connecting frame 1131b on the left side, and the second leg massage unit 1330 can be disposed in front of the leg connecting frame 1131b on the left side.

[0200] The following describes a massage method using PNF stretching according to an embodiment of the present invention.

[0201] Proprioceptive neuromuscular facilitation (PNF) is a physical therapy developed in the United States for the rehabilitation of cerebral palsy or cerebral infarction. It is a method of effectively treating the affected muscle by utilizing the functions of special muscle spindles located within the muscle and the Golgi tendon organ (GTO), which connects the bones and muscles, to relax and contract the muscle.

[0202] When PNF stretching is performed, autogenic and reciprocal inhibitory responses occur in the body through the muscle spindles (which act as length detectors, responding to changes in muscle length and speed and contracting the muscle when its speed or length changes suddenly) and the Golgi tendon organ (located on the tendon, sensing tension and relaxing the muscle when the tendon is pulled by force), which act as safety devices.

[0203] The mechanism of PNF (autogenic inhibition) is to reduce muscle excitability through inhibitory signals from the Golgi Tendon Organ (GTO) located in the muscle that needs to be stretched. This reduces muscle tension through intentional contraction, thereby increasing the range of motion.

[0204] Furthermore, it is a reflexive relaxation that occurs when the same muscle containing the Golgi tendon organ undergoes concentric or static contraction and is then manually stretched again, which inhibits the hamstring (agonist muscle) and activates the quadriceps (antagonist muscle).

[0205] When a muscle that needs to be stretched at the end of its range of motion contracts, the sensory nerve connected to the muscle sends a signal to the spinal cord. This nerve encounters an inhibitory interneuron within the spinal cord, thereby reducing the activity of the motor nerves outside the spinal cord.

[0206] Autogenic inhibition is caused by this self-regulating mechanism of GTO to protect structures from excessive tension. In PNF stretching, muscle tension is reduced through intentional contraction, thereby increasing range of motion.

[0207] Secondly, the mechanism of PNF (mutual inhibition) is a technique that relaxes a muscle by transmitting an inhibitory signal to the agonist when the muscle on the opposite side (antagonist) to the muscle that needs to be stretched is intentionally contracted and activated. This is done by the following process: after the last range of tension in the hamstring (agonist) has stopped, the quadriceps femoris (antagonist), which is the muscle on the opposite side, is contracted.

[0208] At this time, if the sensory nerve connected to the quadriceps muscle contracts, receives the signal, and transmits it to the spinal cord, the motor nerve connected to the quadriceps muscle receives the activation signal in the spinal cord, thereby contracting the muscle.

[0209] To facilitate this signal, the hamstring encounters an inhibitory interneuron, reducing the activity of extraspinal motor nerves and inhibiting (relaxing) them.

[0210] The therapeutic goals of this PNF stretching can include: 1) coordinated activity achievement based on timing; 2) increasing the patient's physical strength and avoiding fatigue; 3) increasing the patient's mobility; 4) increasing the patient's ability to maintain stability; and 5) guiding activity through appropriate levels of contact and resistance.

[0211] Therefore, it can provide the following effects: 1) Improved coordination; 2) Increased sense of movement; 3) Guidance for normal movement ratios; 4) Promoted muscle relaxation; 5) Active regulation; 6) Increased range of motion; 7) Improved muscle strength and endurance; 8) Functional training that regulates eccentricity of movement; 9) Prevention and reduction of fatigue; 10) Improved stability; 11) Increased coordination between antagonist and agonist muscles; 12) Reduced pain, etc.

[0218] The first center bushing 1311 and the first side bushing 1312 may comprise a resin material. As an example, the first center bushing 1311 and the first side bushing 1312 may comprise a resin material. As an example, the synthetic resin may comprise polyacetal (POM). Because the first center bushing 1311 and the first side bushing 1312 comprise a synthetic resin, wear resistance and fatigue resistance can be improved.

[0219] Additionally, the first center bushing 1311 and the first side bushing 1312 may comprise glass fiber. Because the first center bushing 1311 and the first side bushing 1312 comprise glass fiber, corrosion resistance and insulation can be improved.

[0220] Alternatively, the first center bushing 1311, the first side bushing 1312, and the first shaft 1313 can be manufactured integrally. In this case, the first center bushing 1311, the first side bushing 1312, and the first shaft 1313 can be made of the same material. As an example, the first center bushing 1311, the first side bushing 1312, and the first shaft 1313 can be made of a metallic material.

[0221] The first center bushing 1311 and the first side bushing 1312 can be rotatably fixed to the center support bracket 1530 and the side support bracket 1550, respectively.

[0222] A first center support rib 1311a may be provided protrudingly on the outer peripheral surface of the first center bushing 1311 to prevent detachment from the center support bracket 1530. The first center support rib 1311a may be provided radially outward. The bearing 1533 may be coupled to the outer peripheral surface of the first center bushing 1311 where the first center support rib 1311a is not formed. The bearing 1533 may be supported by the center support bracket 1530.

[0224] The second leg massage unit 1330 may include a second central bushing 1321, a second side bushing 1322, a second shaft 1323, and a second leg frame 1324. A second central support rib 1321a may be disposed on the outer peripheral surface of the second central bushing 1321, and a bearing 1533 may be coupled to the outer peripheral surface where the second central support rib 1321a is not formed. A second side support rib 1322a may be disposed on the outer peripheral surface of the second side bushing 1322, and a bearing 1533 may be coupled to the outer peripheral surface where the second side support rib 1322a is not formed.

[0225] The structure consists of constituent elements corresponding to the first central bushing 1311, first side bushing 1312, first shaft 1313, and first leg frame 1314 of the first leg massage unit 1310, respectively, and has the same function and structure (left-right symmetry). Therefore, the repeated description of the specific structure of the second leg massage unit 1330 will be omitted and replaced with the above description.

[0226] Figure 10A This diagram illustrates the state of the shaft connected to the central support bracket and the side support bracket according to an embodiment of the present invention. Figure 10B This is a diagram showing the state of rotation of the central rotating component. Figure 11 yes Figure 10A A schematic top view, Figure 12A It is along Figure 10A A cross-sectional view of line C-C'. Figure 12B This is another embodiment of the present utility model. Figure 10A A cross-sectional view of the C-C' line.

[0227] Referring to Figures 10 to 12, the central support bracket 1530 and the side support bracket 1550 can be connected to the leg connection frame 1131b.

[0228] The central support bracket 1530 can be disposed at the center of the leg connecting frame 1131b. The central support bracket 1530 can rotatably fix the first central bushing 1311 of the first leg massage part 1310 and the second central bushing 1321 of the second leg massage part 1330.

[0229] On the other hand, to ensure smooth rotation between the central support bracket 1530 and the central bushings 1311 and 1321, a bearing 1533 (see reference) can be provided. Figure 12B Bearing 1533 may include various bearings used in the technical field to which this utility model pertains, such as ball bearings, thrust bearings, needle roller bearings, cylindrical bearings, spherical roller bearings, etc.

[0230] The central support bracket 1530 may include a central fixing member 1531 and a central rotating member 1532.

[0231] The central fixing member 1531 can be welded to the leg connecting frame 1131b or can be joined by a separate fastening member. One side of the central rotating member 1532 can be rotatably hinged to the central fixing member 1531. When the central rotating member 1532 rotates so that its end contacts the central fixing member 1531, the connection can be made by a fastening member.

[0232] The central fixing member 1531 may include a first central fixing member 1531a and a second central fixing member 1531b. The first central fixing member 1531a and the second central fixing member 1531b may be configured with corresponding shapes.

[0233] The central rotating member 1532 may include a first central rotating member 1532a and a second central rotating member 1532b. The first central rotating member 1532a and the second central rotating member 1532b may be configured with corresponding shapes.

[0234] The first central rotating member 1532a and the second central rotating member 1532b can be rotatably coupled to the first central fixing member 1531a and the second central fixing member 1531b, respectively.

[0235] The first center fixing member 1531a and the first center rotating member 1532a can rotatably fix the first center bushing 1311. The second center fixing member 1531b and the second center rotating member 1532b can rotatably fix the second center bushing 1321.

[0236] Figure 13A This is a diagram showing a central support bracket according to another embodiment of the present invention. Figure 13B This is a diagram showing a central support bracket according to another embodiment of the present invention.

[0237] Reference Figure 13A The first central rotating member 1532a and the second central rotating member 1532b can be connected via a central rotating member cover 1532c. For example, one side of the central rotating member cover 1532c can be connected to the inside of the first central rotating member 1532a, and the other side can be connected to the inside of the second central rotating member 1532b. The central rotating member cover 1532c can be welded to the first central rotating member 1532a and the second central rotating member 1532b, or it can be connected via separate fastening members. However, the first central rotating member 1532a, the second central rotating member 1532b, and the central rotating member cover 1532c can also be integrated. In other words, the first central rotating member 1532a, the second central rotating member 1532b, and the central rotating member cover 1532c can be integrated by repeatedly bending and cutting a single member.

[0238] Reference Figure 13B The center rotating member cover 1532c can be connected to the outside of the first center rotating member 1532a and the second center rotating member 1532b. The center rotating member cover 1532c can be welded to the first center rotating member 1532a and the second center rotating member 1532b or connected via separate fastening members. In this case, the center rotating member cover 1532c can be configured to integrally cover the upper part of the first center rotating member 1532a and the second center rotating member 1532b.

[0239] Furthermore, the central rotating member cover 1532c can be connected to the first central rotating member 1532a and the second central rotating member 1532b via mechanical structures such as sliding or hook connections. As long as the central rotating member cover 1532c corresponds to a structure configured to cover at least a portion of the upper part of the first central rotating member 1532a and the second central rotating member 1532b, the structure of the central rotating member cover 1532c can be replaced by various methods commonly used in the technical field to which this invention pertains.

[0240] The central support bracket 1530 may correspond to a component of the safety sensor module 1500, which will be described later. The specific structure of the central support bracket 1530 will be described in detail later.

[0241] Side support brackets 1550 can be disposed on both sides of the leg connecting frame 1131b. The side support brackets 1550 may include a first side support bracket 1550a disposed on the left end of the leg connecting frame 1131b and a second side support bracket 1550b disposed on the left end. The first side support bracket 1550a and the second side support bracket 1550b may be configured with corresponding shapes.

[0242] The first side support bracket 1550a can rotatably fix the first side bushing 1312. The second side support bracket 1550b can rotatably fix the second side bushing 1322. Bearings can be provided to allow smooth rotation between the side support brackets 1550 and the side bushings 1312 and 1322.

[0243] For example, the side support bracket 1550 may include a side fixing member 1551 and a side rotating member 1552.

[0244] The side fixing member 1551 can be welded to the leg connection frame 1131b or can be attached by a separate fastening member. The side fixing member 1551 can be rotatably attached 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, the connection can be made by a fastening member.

[0245] Figure 14A and Figure 14B This diagram illustrates the process of fastening the center bushing to the center support bracket. Figure 14C and Figure 14D This diagram illustrates the process of fastening the side bushing to the side support bracket.

[0246] Reference Figure 14A and Figure 14B The process of fastening the first center bushing 1311 to the center support bracket 1530 is explained.

[0247] The first central fixing member 1531a can be combined with the leg connecting frame 1131b. For example, the first central fixing member 1531a can be welded to the leg connecting frame 1131b with the leg connecting frame 1131b inserted into the leg connecting frame insertion slot 1531d-1, or it can be combined with a separate fastening member, the leg connecting frame insertion slot 1531d-1 being formed on one side of the first central fixing member 1531a.

[0248] When the first central fixing member 1531a is engaged with the leg connecting frame 1131b, the first central rotating member 1532a can rotate upward. For example, the first central rotating member 1532a can be rotatably hinged to the first central fixing member 1531a via a central rotating shaft 1532a-1, and can rotate 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 integrated with either the first central fixing member 1531a or the first central rotating member 1532a.

[0249] The first center bushing 1311 can be placed in the center bushing receiving groove 1531d-5 of the first center fixing member 1531a.

[0250] When the first center bushing 1311 is installed, the first center rotating member 1532a can rotate downwards. At this time, at least a portion of the upper outer 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 receiving groove 1531d-5 and the center bushing fixing groove 1532d can rotatably support the first center bushing 1311.

[0251] When the first central rotating member 1532a rotates downward and its end contacts the fixing piece 1531d-4 of the first central fixing member, the first central rotating member 1532a can be connected to the fixing piece 1531d-4 by a fastening member.

[0252] 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.

[0253] Reference Figure 14B and Figure 14C The process of fastening the first side bushing 1312 to the first side support bracket 1550a is described.

[0254] The side fixation member 1551 can be combined with the leg connection frame 1131b. For example, the side fixation member 1551 can be welded to the leg connection frame 1131b or it can be combined with a separate fastening member.

[0255] When the side fixing member 1551 is engaged with the leg connecting frame 1131b, the side rotating member 1552 can rotate upward. For example, the side rotating member 1552 can be rotatably hinged to the side fixing member 1551 via a side rotation axis 1552b, and can rotate upward based on the side rotation axis 1552b. Here, the side rotation axis 1552b can refer to a separate rotation axis that rotatably connects the side fixing member 1551 and the side rotating member 1552. However, the side rotation axis 1552b can also be integrated with either the side fixing member 1551 or the side rotating member 1552.

[0256] The first side bushing 1312 can be placed in the side bushing receiving groove 1551a of the side fixing member 1551.

[0257] When the first side bushing 1312 is installed, the side rotating member 1552 can rotate downward. At this time, at least a portion of the upper outer peripheral surface of the first side bushing 1312 can be accommodated in the side bushing fixing groove 1552a of the side rotating member 1552. The side bushing receiving groove 1551a and the side bushing fixing groove 1552a can rotatably support the first side bushing 1312.

[0258] When the side rotating member 1552 rotates downward and its end contacts the side fixing member 1551, the side rotating member 1552 can be connected to the side fixing member 1551 by a fastening member.

[0259] 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.

[0260] As described above, the leg massage unit 1300 can be easily connected to the body massage unit 1100 because the center bushing and side bushings can be fixed by placing them on the center support bracket 1530 and the side support bracket 1550 and fastening them.

[0261] Figure 15 yes Figure 7 Enlarged view of part D, Figure 16 This is a diagram showing the disassembled state of a safety sensor module according to an embodiment of the present invention. Figure 17 This is a diagram illustrating another embodiment of the safety sensor module of this utility model.

[0262] Reference Figure 15 and Figure 16 According to one embodiment of the present invention, the massage device 1000 may include a safety sensor module 1500.

[0263] The safety sensor module 1500 may be disposed in the leg connection frame 1131b. For example, the safety sensor module 1500 may be disposed in a portion of the leg connection frame 1131b, which corresponds to the space between the first leg massage unit 1310 and the second leg massage unit 1330.

[0264] When an external force is applied, the safety sensor module 1500 can control the drive of at least one of the first leg massage unit 1310 and the second leg massage unit 1330. For example, when an external force is applied, the safety sensor module 1500 can stop the rotational movement of at least one of the first leg massage unit 1310 and the second leg massage unit 1330. Additionally, when an external force is applied, the safety sensor module 1500 can rotate the first leg massage unit 1310 and the second leg massage unit 1330 by a predetermined angle in a direction opposite to the rotational direction of at least one of the first leg massage unit 1310 and the second leg massage unit 1330.

[0265] The safety sensor module 1500 may include an alarm unit (not shown in the drawings for ease of illustration) that sends a warning signal to the user when an external force is applied. The alarm unit may include at least one of, for example, a light source, an audio source, and a vibration element. The light source can send a warning signal by shining light on the user. The audio source may correspond to the audio output module 1120 or may refer to a separate audio device. The audio source can send a warning signal to the user via an alarm sound. The vibration element may be configured as a vibration panel, a vibration actuator, etc. The vibration element can send a warning signal by applying vibration to the user by being disposed in at least one of the body massage unit 1100, arm massage unit 1200, and leg massage unit 1300. In this case, the light source and / or the vibration element may be disposed in the leg massage unit 1300. For example, the light source may be disposed at various locations on the exterior (or exterior) of the leg massage unit 1300. The vibration element may be disposed in areas of the leg massage unit 1300 adjacent to the user's body (e.g., areas corresponding to the soles of the feet and areas corresponding to the calves, etc.).

[0266] Therefore, the safety sensor module 1500 can prevent safety accidents that may occur due to the user's body being trapped between the leg massage units 1300. Additionally, the safety sensor module 1500 can prevent device damage / malfunction that may occur due to objects flowing into the leg massage units 1300.

[0267] The safety sensor module 1500 may include a sensor bracket 1510, a sensor 1520, a central support bracket 1530, and a pressure plate 1540.

[0268] A sensor bracket 1510 can be provided to support the sensor 1520. The sensor bracket 1510 can be coupled to the leg connection frame 1131b. For example, the sensor bracket 1510 can be welded to the leg connection frame 1131b or coupled by a separate fastening member. The method of coupling the sensor bracket 1510 to the leg connection frame 1131b can be replaced by various methods common in the art to which this invention pertains.

[0269] The sensor bracket 1510 may include a protruding portion 1511 and a bent portion 1512. One side of the protruding portion 1511 may be coupled to the leg connecting frame 1131b, and the other side may protrude forward. The bent portion 1512 may bend downward at the other end of the protruding portion 1511. Therefore, the sensor bracket 1510 can be configured as follows: Shape. The sensor connection hole 1512a can be provided in the curved portion 1512.

[0270] Sensor 1520 can be attached to sensor bracket 1510. For example, sensor 1520 can be attached to a curved portion 1512 of sensor bracket 1510. In this case, at least a portion of sensor 1520 can be configured to pass through sensor attachment hole 1512a. Therefore, at least a portion of sensor 1520 can protrude forward of curved portion 1512.

[0271] Sensor 1520 can detect contact with pressure plate 1540. For example, when an external force is applied to pressure plate 1540 to rotate it, pressure plate 1540 may come into contact with sensor 1520. When in contact with pressure plate 1540, sensor 1520 can transmit corresponding information to control unit 1400. When receiving information from sensor 1520 that contact with pressure plate 1540 has been established, as described above, control unit 1400 can control the drive of at least one of the first leg massage unit 1310 and the second leg massage unit 1330. Additionally, control unit 1400 can send a warning signal to the user by activating an alarm unit.

[0272] Sensor 1520 can be configured as a sensor that uses measurement methods such as pressure, potential, and optics. As an example, sensor 1520 may include: sensor housing 1521; contact portion 1522 disposed in sensor housing 1521 and detecting contact with pressure plate 1540; fastening portion 1523 for fastening to sensor bracket 1510; and electrode terminal 1524 for electrical connection to external device.

[0273] When pressure is applied through the pressure plate 1540, the contact portion 1522 can slide inward toward the inside of the sensor housing 1521. For this purpose, a separate elastic member can be provided on the inside of the sensor housing 1521 to apply elastic force to the contact portion 1522. When the contact portion 1522 slides inward toward the inside of the sensor housing 1521 under pressure, the sensor 1520 can send a signal to the control unit 1400. Therefore, as described above, the control unit 1400 can control the operation of at least one of the first leg massage portion 1310 and the second leg massage portion 1330, or can send a warning signal to the user via the alarm unit.

[0274] A fastening part 1523 can be provided to engage with the sensor holder 1510. The fastening part 1523 can be made of a resilient material and can be inserted into the sensor engagement hole 1512a formed in the sensor holder 1510 when the sensor 1520 is fastened. To facilitate insertion into the sensor engagement hole 1512a, the fastening part 1523 may include an inclined surface. The inclined surface can be configured such that, with one end fixed to the sensor housing 1521, the distance from the sensor housing 1521 increases from the rear to the front of the sensor 1520. Additionally, to facilitate contact with the sensor engagement hole 1512a, a flat surface can be provided at the other end of the inclined surface. The flat surface can contact the inner surface of the sensor engagement hole 1512a. When held by a user, the fastening part 1523 can fold towards the sensor housing 1521. Therefore, when it is necessary to separate the sensor 1520, the user can separate the sensor 1520 from the sensor holder 1510 by holding the fastening part 1523.

[0275] On the other hand, as long as the rotation or contact of the pressure plate 1540 can be detected, various sensors commonly used in the technical field to which this invention pertains can replace sensor 1520. For example, sensor 1520 may include at least one of a pressure sensor, an infrared sensor, an LED sensor, a touch sensor, and an electrode sensor.

[0276] The central support bracket 1530 can be disposed on both sides of the sensor bracket 1510. The central support bracket 1530 can be manufactured as a separate component from the sensor bracket 1510 or can be manufactured integrally with the sensor bracket 1510. Alternatively, after manufacturing the central support bracket 1530 and the sensor bracket 1510 as separate components, they can be joined by welding or other methods. The method of joining the central support bracket 1530 and the sensor bracket 1510 can be replaced by various methods common in the technical field to which this invention pertains. The pressure plate 1540 can be rotatably connected to the central support bracket 1530. The central support bracket 1530 may include a central fixing member 1531 and a central rotating member 1532.

[0277] For example, the central fixing member 1531 may include: a base 1531c; and side portions 1531d projecting upward from both sides of the base 1531c. The base 1531c and side portions 1531d may be formed by bending a single member. However, the base 1531c and side portions 1531d may also be manufactured as separate members and then joined together.

[0278] The base 1531c may form the bottom surface of the central fixing member 1531. At least one stop 1531e may be provided in the base 1531c. The stop 1531e may limit the angle of rotation of the pressure plate 1540 away from the sensor 1520. The stop 1531e may extend through the base 1531c and its end may protrude downward from the base 1531c. When a single stop 1531e is provided, the stop 1531e may be configured in the central region of the base 1531c; when multiple stops are provided, at least one may be configured in the central region and the side regions of the base 1531c.

[0279] The position and structure of the stop 1531e can be varied to limit the rotation angle of the pressure plate 1540. For example, the stop 1531e can be attached to the bottom surface of the base 1531c, so that the entire stop 1531e protrudes downward from the base 1531c. Alternatively, the stop 1531e can be manufactured integrally with the base 1531c. Alternatively, the stop 1531e can be disposed on the pressure plate 1540.

[0280] Side portion 1531d may include a leg connecting frame insertion slot 1531d-1. Leg connecting frame 1131b can be inserted into and coupled to leg connecting frame insertion slot 1531d-1. Leg connecting frame insertion slot 1531d-1 can be formed by cutting the end of side portion 1531d facing leg connecting frame 1131b. Leg connecting frame insertion slot 1531d-1 can be configured such that its inner surface engages with the outer surface of leg connecting frame 1131b. When leg connecting frame 1131b is inserted into leg connecting frame insertion slot 1531d-1, the portion of side portion 1531d in contact with leg connecting frame 1131b can be welded. However, the method of coupling side portion 1531d and leg connecting frame 1131b can be replaced by various methods common in the technical field to which this invention pertains.

[0281] Side portion 1531d may include a central rotating member insertion slot 1531d-2. The central rotating member 1532 may be rotatably hinged to the central rotating member insertion slot 1531d-2. The central rotating member insertion slot 1531d-2 may be positioned at various locations on the side portion 1531d, such that the central rotating member 1532 is rotatable on the upper part of the side portion 1531d.

[0282] Side portion 1531d may include pressure plate insertion slot 1531d-3. One side of pressure plate 1540 may be rotatably hinged to pressure plate insertion slot 1531d-3. Pressure plate insertion slot 1531d-3 may be positioned on the other side of pressure plate 1540 and rotate upward (see reference). Figure 16 ) or rotate downwards ( Figure 17 (Refer to) the various positions of the side portion 1531d that contact the sensor 1520 when rotated at an angle above a predetermined angle. For example, the pressure plate insertion slot 1531d-3 can be provided on the lower front side of the side portion 1531d (refer to) Figure 16 ) or the upper front (refer to) Figure 17 ).

[0283] Either of the side portions 1531d protruding from both sides of the base 1531c may be provided with a fixing piece 1531d-4 that bends toward the other side portion 1531d. However, the fixing piece 1531d-4 may also be manufactured as a separate component and attached to both side portions 1531d. When the central rotating member 1532 rotates and its end contacts the fixing piece 1531d-4, the end of the central rotating member 1532 and the fixing piece 1531d-4 may be connected by a fastening member.

[0284] Side portion 1531d may include a central bushing receiving groove 1531d-5. Central bushings 1311, 1321 may be rotatably mounted in the central bushing receiving groove 1531d-5. For example, the central bushing receiving groove 1531d-5 may be provided by cutting off the upper end of side portion 1531d.

[0285] The central rotating member 1532 can be rotatably hinged to the side portion 1531d. The central rotating member 1532 may include a central bushing retaining groove 1532d. When the central rotating member 1532 rotates and is connected to the retaining piece 1531d-4 of the side portion 1531d, the central bushing retaining groove 1532d can rotatably support the central bushings 1311 and 1321 together with the central bushing receiving groove 1531d-5.

[0286] The pressure plate 1540 may be rotatably hinged to the central support bracket 1530. The pressure plate 1540 may include an elastic member 1541. The elastic member 1541 may apply a spring force to the pressure plate 1540, causing the free end of the pressure plate 1540 to rotate away from the sensor 1520. The elastic member 1541 may be configured as various members capable of applying a spring force to the pressure plate 1540. As an example, the elastic member 1541 may be configured as a torsion spring. When the elastic member 1541 is configured as a torsion spring, as the pressure plate 1540 rotates, the two ends of the torsion spring may contact at least one of the pressure plate 1540 and the central support bracket 1530.

[0287] When the user's body or other objects are not sandwiched between the leg massage parts 1300 or between the leg massage parts 1300 and the body massage parts 1100, the elastic member 1541 can simply prevent the user's body or other objects from contacting the pressure plate 1540 so that the pressure plate 1540 can rotate.

[0288] The pressure plate 1540 can rotate and come into contact with the sensor 1520. For example, when an external force greater than the elastic force of the elastic member 1541 is applied to the pressure plate 1540, the pressure plate 1540 can rotate and come into contact with the sensor 1520.

[0289] Figure 18A and Figure 18B This is a diagram illustrating the process of driving a safety sensor module according to an embodiment of the present invention.

[0290] Reference Figure 18A Through the elastic force of the elastic member 1541, one end of the pressure plate 1540 can be configured to be separated from the sensor 1520, while the other end can be in contact with the stop 1531e. Since the elastic force is continuously applied to the pressure plate 1540, if the predetermined external force is not applied for a predetermined time, one end of the pressure plate 1540 may not be in contact with the sensor 1520.

[0291] Reference Figure 18B When the user's body is sandwiched between the leg massage units 1300 and / or between the leg massage unit 1300 and the body massage unit 1100, and at least one of the leg massage unit 1300 and the body massage unit 1100 rotates, an external force F exceeding the elastic force of the elastic member 1541 can be applied to the pressure plate 1540. Furthermore, the external force F can continue to act on the pressure plate 1540 as long as the clamping state is not released. In this situation, the pressure plate 1540 can rotate, and one end can contact the sensor 1520. When the pressure plate 1540 contacts the sensor, the sensor 1520 can transmit corresponding information to the control unit 1400. When the control unit 1400 receives information from the sensor 1520 that the pressure plate 1540 has been contacted, it can control the actuation of at least one of the first leg massage unit 1310, the second leg massage unit 1330, and the body massage unit 1100, or it can activate the alarm unit. Therefore, it can prevent safety accidents that may occur due to the user's body being sandwiched between the leg massage units 1300 and / or between the leg massage units 1300 and the body massage units 1100.

[0292] Furthermore, it can prevent equipment malfunctions and damage that may occur due to objects other than the user's body being trapped between the leg massage units 1300 or between the leg massage units 1300 and the body massage units 1100.

[0293] For ease of explanation, the leg massage unit 1300 will be changed to the leg massage unit 2000, the first leg massage unit 1310 will be changed to the first leg massage unit 2000a, and the second leg massage unit 1330 will be changed to the second leg massage unit 2000b.

[0294] Figure 19 This diagram schematically illustrates the leg length adjustment module of the leg massage unit 2000 according to an embodiment of the present invention. Figure 20 This diagram illustrates the principle of length adjustment for the 2000 leg massage unit. Figure 21 It is magnification Figure 19 The diagram in part B, Figure 22 It is magnification Figure 19 The diagram for part C.

[0295] Reference Figure 19 The massage device 1000 may include a leg length adjustment module 2500 for adjusting the length of the leg massage unit 2000. In this case, the leg length adjustment module 2500 can adjust the length of the leg massage unit 2000 based on the control of the control unit 1400.

[0296] The leg length adjustment module 2500 may include a first leg length adjustment module 2500a and a second leg length adjustment module 2500b.

[0297] The first leg length adjustment module 2500a may be included in the first leg massage unit 2000a. For example, the first leg length adjustment module 2500a may be disposed behind the first leg massage unit 2000a. Specifically, the first leg length adjustment module 2500a may be disposed between the rear of the first leg massage unit 2000a and the front of the first leg angle adjustment module 1350a.

[0298] The first leg length adjustment module 2500a can adjust the length of the first leg massage unit 2000a by moving the position of the first leg massage unit 2000a. At this time, the first leg length adjustment module 2500a can adjust the length of the first leg massage unit 2000a based on the length of one of the user's legs.

[0299] As an example, the first leg length adjustment module 2500a can adjust the length of the first leg massage unit 2000a by moving the first leg massage unit 2000a in at least one of the upper (or upper direction) and lower (or lower direction) directions. In this case, the upper direction of the first leg massage unit 2000a can be from the lower side of the first leg massage unit 2000a toward the upper side of the first leg massage unit 2000a, and the lower direction of the first leg massage unit 2000a can be from the upper side of the first leg massage unit 2000a toward the lower side of the first leg massage unit 2000a.

[0300] As another example, the first leg length adjustment module 2500a can move at least one of the first upper leg massage unit 2000aa and the first lower leg massage unit 2000ab of the first leg massage unit 2000a in at least one direction between the upper and lower sides of the first leg massage unit 2000a and adjust (or regulate) the distance between the first upper leg massage unit 2000aa and the first lower leg massage unit 2000ab, thereby adjusting the length of the first leg massage unit 2000a. In this case, the first upper leg massage unit 2000aa can massage the upper part of one leg (e.g., the calf). For example, the first upper leg massage unit 2000aa may include a massage module such as an airbag and rollers for massaging the upper part of the leg in at least a portion of its entire area. The second lower leg massage unit 2000ab can massage the lower part of the user's other leg (e.g., the foot). For example, the second lower leg massage unit 2000ab may include a massage module such as an airbag and rollers for massaging the lower part of the leg in at least a portion of the entire area of ​​the second lower leg massage unit 2000ab.

[0301] The second leg length adjustment module 2500b may be included in the second leg massage unit 2000b. For example, the second leg length adjustment module 2500b may be disposed behind the second leg massage unit 2000b. Specifically, the second leg length adjustment module 2500b may be disposed between the rear of the second leg massage unit 2000b and the front of the second leg angle adjustment module 1350b.

[0302] The second leg length adjustment module 2500b can adjust the length of the second leg massage unit 2000b by moving the position of the second leg massage unit 2000b. At this time, the second leg length adjustment module 2500b can adjust the length of the second leg massage unit 2000b based on the length of the user's other leg.

[0303] As an example, the second leg length adjustment module 2500b can adjust the length of the second leg massage unit 2000b by moving the second leg massage unit 2000b in at least one of the upper (or upper direction) and lower (or lower direction) directions. In this case, the upper direction of the second leg massage unit 2000b can be from the lower side of the second leg massage unit 2000b toward the upper side of the second leg massage unit 2000b, and the lower direction of the second leg massage unit 2000b can be from the upper side of the second leg massage unit 2000b toward the lower side of the second leg massage unit 2000b.

[0304] As another example, the second leg length adjustment module 2500b can adjust 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 in at least one of the upper and lower directions of the second leg massage part 2000b, thereby adjusting the length 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.

[0305] In other words, the length of each leg massage unit 2000a and 2000b can be adjusted by the adjustment module of each leg massage unit based on the length of each leg.

[0306] Specifically, refer to Figure 19 and Figure 20 The adjustment modules 2500a and 2500b may include guide screws 2510a and 2510b for adjusting the distance between the upper leg massage units 2000aa and 2000ba and the lower leg massage units 2000ab and 2000bb, and leg length adjustment actuators 2520a and 2520b for providing power to the guide screws 2510a and 2510b.

[0307] According to a preferred embodiment, the guide screws 2510a and 2510b may have a helix formed along their outer surfaces, and the inner surface of the leg frame 2210 is formed corresponding to the guide screws 2510a and 2510b, and may include a member through which the guide screws 2510a and 2510b pass. Furthermore, the leg frame 2210 may be provided in the upper leg massage portions 2000aa and 2000ba, and the guide screws 2510a and 2510b and leg length adjustment actuators 2520a and 2520b may be provided in the lower leg massage portions 2000ab and 2000bb.

[0308] The guide screws 2510a and 2510b can be rotated by the leg length adjustment actuators 2520a and 2520b. While rotating, the guide screws 2510a and 2510b pass through the fixed component in a spiral manner and can move up and down. As a result, the lower leg massage units 2000ab and 2000bb can move closer to or further away from the leg massage units 2000aa and 2000ba as the guide screws 2510a and 2510b rotate. Therefore, the distance between the upper leg massage units 2000aa and 2000ba and the lower leg massage units 2000ab and 2000bb can be adjusted, thereby adjusting the length of the first leg massage unit 2000a and the second leg massage unit 2000b.

[0309] Reference Figure 21 Guide rails 2211a and 2211b can be formed on the inner sides of the leg frames 2210a and 2210b. Furthermore, the first leg massage unit 2000a and the second leg massage unit 2000b may include guide rollers 2540a and 2540b that move along the guide rails 2211a and 2211b, and guide rods 2530a and 2530b for supporting the guide rollers 2540a and 2540b. At this time, one end of the guide rods 2530a and 2530b is connected to the lower leg massage units 2000ab and 2000bb. Therefore, as the guide screws 2510a and 2510b rotate, the guide rods 2530a and 2530b and the guide rollers 2540a and 2540b can move in the same direction as the lower leg massage units 2000ab and 2000bb.

[0310] On the other hand, guide rollers 2540a and 2540b can move along guide rails 2211a and 2211b. Therefore, guide rollers 2540a and 2540b can guide the lower leg massage units 2000ab and 2000bb in a way that allows them to move in the appropriate direction. Therefore, when the lower leg massage units 2000ab and 2000bb move, the leg massage units 2000a and 2000b on both sides can remain still.

[0311] On the other hand, guide rails 2211a and 2211b can be formed on a portion of the inner side of the leg frame 2210. (See reference...) Figure 21 Guide rails 2211a and 2211b are formed only on a portion of the inner side of the leg frame 2210, while claws are formed on the remaining portion, thereby preventing the movement of guide rollers 2540a and 2540b. Therefore, the lower leg massage units 2000ab and 2000bb can be prevented from moving to their limit points, and the problem of the lower leg massage units 2000ab and 2000bb completely detaching from the upper leg massage units 2000aa and 2000ba can be prevented.

[0312] On the other hand, in order to more properly guide the movement of the guide rods 2530a and 2530b, the leg massage unit 2000 may also include guide wheels 2551a and 2551b and guide wheel supports 2552a and 2552b that accommodate and support the guide wheels 2551a and 2551b. (See reference...) Figure 22 At least one guide wheel 2551a, 2551b can be disposed inside the guide wheel brackets 2552a, 2552b. The outer surface of the guide wheels 2551a, 2551b can be formed to be concave inward, and the guide rods 2530a, 2530b can be inserted into the concave 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 that they do not deviate from the movement path. As a result, the guide wheels 2551a, 2551b support the guide rods 2530a, 2530b so that the guide rods 2530a, 2530b do not wobble when moving, and can guide the movement path so that the guide rods 2530a, 2530b move in the appropriate direction. Therefore, the lower leg massage sections 2000ab and 2000bb can also be moved in the appropriate direction via the guide rods 2530a and 2530b without wobbling.

[0313] Figure 23 This is a diagram showing a foot massage unit 2600 according to an embodiment of the present invention.

[0314] The lower leg massage units 2000ab and 2000bb may include foot massage units 2610 and 2630 on one side. Preferably, the foot massage units 2610 and 2630 may be located at the lowest or bottommost end of the lower leg massage units 2000ab and 2000bb.

[0315] Foot massage units 2610 and 2630 may include at least one foot massage module (or massage unit for massaging the feet) and a foot massage actuator (or foot drive unit) for driving at least one foot massage module. For example, a first leg massage unit 2000a may include a first foot massage unit 2610 disposed in an area corresponding to the sole of the foot on one of the user's legs. A second leg massage unit 2000b may include a second foot massage unit 2630 disposed in an area corresponding to the sole of the foot on the other leg of the user.

[0316] The second leg massage unit 2000b includes a second foot massage unit 2630 disposed in the area corresponding to the sole of the user's other leg. A first foot massage module 2612 and a second foot massage module 2613 are respectively arranged (or configured) in front of and behind the first foot massage unit 2610, providing massage to the entire sole of the user's one leg. Furthermore, the first foot massage unit 2610 may include first foot massage actuators 2611 and 2613 for driving at least one foot massage module. The first foot massage actuators 2611 and 2613 may be disposed in front of the first foot massage unit 2610 and in front of the first foot massage module 2612, driving at least one foot massage module. In this case, the area in front of the first foot massage unit 2610 and the area in front of the first foot massage module 2612 may be the entire area of ​​the first foot massage unit 2610 corresponding to the toes of one leg.

[0317] The second foot massage unit 2630 may include at least one of a third foot massage module 2632 and a fourth foot massage module 2633. For example, the third foot massage module 2632 and the fourth foot massage module 2633 are respectively arranged (or configured) in front of and behind the second foot massage unit 2630, providing massage to the entire sole of the user's other leg. Furthermore, the first foot massage unit 2630 may include a first 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 unit 2630 and in front of the third foot massage module 2632, driving at least one foot massage module. In this case, the area in front of the second foot massage unit 2630 and the area in front of the third foot massage module 2632 may be the entire region of the second foot massage unit 2630 corresponding to the toes of one leg.

[0318] As described above, the first foot massage unit 2610 and the second foot massage unit 2630 include two foot massage modules and a foot massage actuator, but are not limited thereto. For example, each of the first foot massage unit and the second foot massage unit may include multiple foot massage modules (e.g., more than three), such as... Figure 23 As shown, each foot massage module can be configured in a straight line. In this case, the straight line can be a line passing through the sole of the foot. Each of the first and second foot massage units can drive all the foot massage modules in the plurality of foot massage modules through a single foot massage actuator that includes a foot massage actuator.

[0319] On the other hand, at least one protrusion can be formed on the surface of the foot massage module. Therefore, the foot massage module can provide massage to the user's soles by rotating.

[0320] Alternatively, the foot massage module can be a roller with a curved surface. Therefore, the foot massage module can provide massage to the user's soles by rotating.

[0321] On the other hand, as an optional embodiment, the foot massage actuator can be equipped with a cam. Therefore, the foot massage unit can use the cam to provide acupressure massage to the user's toes without rolling massage. Furthermore, by mounting the cam in the foot massage actuator, space efficiency can be improved compared to setting up the foot massage actuator separately.

[0322] Figure 24 This is a diagram showing the anti-pinch sensor S in the leg massage unit 2000 according to an embodiment of the present invention.

[0323] At least one anti-pinch sensor S (or safety sensor) may be disposed at at least one location on the side, rear, and between the upper leg massage units 2000aa, 2000ba and the lower leg massage units 2000ab, 2000bb of the leg massage unit 2000. In this case, the anti-pinch sensor S may be a sensor for identifying that a part of the user's body is pinched between the leg massage units 2000a, 2000b.

[0324] At this time, the anti-pinch sensor S can be a capacitive touch sensor, but is not limited to it.

[0325] When the anti-pinch sensor S is attached to the side of the leg massage unit 2000, it can detect that at least a part of the user's body is sandwiched between the two leg massage units 2000a and 2000b when the leg massage unit 2000 rotates. Alternatively, it can detect that at least a part of the user's body is sandwiched between the leg massage unit 2000 and the body massage unit 1100 when the leg massage unit 2000 rotates.

[0326] With the anti-pinch sensor S attached to the back of the leg massage unit 2000, it can detect when a part of the user's body is pinched behind the leg massage unit 2000 as the leg massage unit 2000 rotates.

[0327] When the anti-pinch sensor S is attached between the upper leg massage units 2000aa, 2000ba and the lower leg massage units 2000ab, 2000bb, it can detect that a part of the user's body is trapped between the upper leg massage units 2000aa, 2000ba and the lower leg massage units 2000ab, 2000bb when the distance between the upper leg massage units 2000aa, 2000ba and the lower leg massage units 2000ab, 2000bb is adjusted.

[0328] Therefore, during the rotation of the leg massage unit 2000, when the user's body is clamped in a specific position of the massage device 1000, the anti-pinch sensor S can identify the situation, and thus the massage device 1000 can stop, thereby preventing safety accidents.

[0329] On the other hand, the anti-pinch sensor S can be formed in an elongated shape. That is, the anti-pinch sensor S can be a linear sensor.

[0330] When the leg massage unit 2000 is rotated or its length adjusted, it is impossible to know which part of the leg massage unit 2000 the user's body will be trapped in. Therefore, when the anti-pinch sensor S extends along the length direction, it can sense whether the area in contact with the user's body widens. Thus, the user can use the massage device 1000 more safely.

[0331] As an optional embodiment, the anti-pinch sensors S can be respectively disposed on the upper leg massage units 2000aa, 2000ba and the lower leg massage units 2000ab, 2000bb. At least one anti-pinch sensor S can be disposed on each surface. For example, the anti-pinch sensors S can be disposed on both sides of the upper leg massage units 2000aa, 2000ba, and also on the left-right side behind the upper leg massage units 2000aa, 2000ba. Additionally, the anti-pinch sensors S can be disposed on the surface between the upper leg massage units 2000aa, 2000ba and the lower leg massage units 2000ab, 2000bb. Furthermore, the anti-pinch sensors S can be disposed on both sides of the lower leg massage units 2000ab, 2000bb.

[0332] Therefore, during the operation of the massage device 1000, even if a part of the user's body, such as the legs, is clamped in any position adjacent to the leg massage unit 2000, this situation can be identified.

[0333] Although not shown in the figure, the leg massage unit 2000 may also include a sensor for controlling the length of the leg massage unit 2000.

[0334] As one embodiment, the leg massage unit 2000 may include at least one limit sensor in the leg frame 2210. The limit sensor may be a sensor for determining the length adjustment limits of the leg massage unit 2000. Alternatively, the limit sensor may be a sensor for determining a reference position of the leg massage unit 2000. For example, the limit sensor may be a Hall sensor, but is not limited thereto.

[0335] By setting limit sensors, the upper leg massage units 2000aa and 2000ba and the lower leg massage units 2000ab and 2000bb can remain in contact with each other beyond a specified limit, which can prevent safety accidents and prevent the lower leg massage units 2000ab and 2000bb from completely separating and detaching from the upper leg massage units 2000aa and 2000ba.

[0336] In another embodiment, the leg massage unit 2000 may include an encoder. Therefore, by using the encoder to identify the distance between the upper leg massage units 2000aa, 2000ba and the lower leg massage units 2000ab, 2000bb, the length adjustment limit of the leg massage unit 2000 is determined. That is, by identifying the distance between the upper leg massage units 2000aa, 2000ba and the lower leg massage units 2000ab, 2000bb using the encoder, the relative movement of the upper leg massage units 2000aa, 2000ba and the lower leg massage units 2000ab, 2000bb can be stopped when a predetermined critical point is reached.

[0337] As one embodiment, the leg massage units 2000a and 2000b may further include a measuring sensor unit for measuring the length of the user's legs. For example, the measuring sensor unit may include at least one of a first measuring sensor and a second measuring sensor. The first leg massage unit 2000a may include a first measuring sensor for measuring the length of one leg, and the second leg massage unit 2000b may include a second measuring sensor for measuring the length of the other leg.

[0338] Preferably, each measuring sensor may include at least one of a first sensor (or a first sub-measuring sensor) and a second sensor (or a second sub-measuring sensor) to measure the user's leg length.

[0339] For example, the first sensor can be a capacitive touch sensor. The first sensor can roughly measure the user's leg length. Therefore, the user's leg length can be measured by the first sensor, and the length of the leg massage units 2000a and 2000b can be adjusted accordingly.

[0340] The first sensor can measure leg length by recognizing the user's body contact. Therefore, the first sensor can measure the user's leg length based on whether the user's body is in contact with the leg, and the massage device 1000 can adjust the length of the leg massage parts 2000a and 2000b accordingly. Although the accuracy is reduced, the length of the leg massage parts 2000a and 2000b can be adjusted quickly and roughly.

[0341] In order to accurately measure the length of the leg massage units 2000a and 2000b according to this utility model, the leg massage units 2000a and 2000b may also include a second sensor.

[0342] For example, the second sensor can be a light sensor or a load sensor. The second sensor can be used to accurately measure the user's leg length. Therefore, after the massage device 1000 roughly measures the user's leg length using the first sensor and adjusts the length of the leg massage units 2000a and 2000b accordingly, it can accurately measure the user's leg length using the second sensor and adjust the length of the leg massage units 2000a and 2000b accordingly.

[0343] Figure 25 This is a flowchart illustrating a massage method utilizing PNF stretching according to an embodiment of the present invention.

[0344] Reference Figure 25 An embodiment of the present invention provides a massage method utilizing PNF stretching, which employs methods including... Figure 1 The stretching method of the massage device 1000 of the leg massage unit 1300 described above firstly involves performing an isotonic motion step (step S1100) while the leg massage unit 1300 is in operation, which guides the direction of the force applied by the user to the leg to the opposite direction of operation of the leg massage unit 1300.

[0345] Here, isotonic motion is a motion method that utilizes isotonic contraction.

[0346] When a muscle contracts, the load applied by the muscle remains constant, but the length of the muscle itself changes. This is called isotonic contraction or dynamic contraction.

[0347] As muscle length changes with the angle of the joint, muscle strength also changes. That is, the same tension will not be produced at the same rate.

[0348] Isotonic contractions include: concentric contraction, where the muscle length decreases and the muscle contracts; and eccentric contraction, where the muscle length increases and the muscle contracts.

[0349] In one embodiment, during the isotonic motion step S1100, while the leg massage unit 1300 is rotating in a specific direction, the user can be introduced by the audio output unit 1440 provided in the massage device 1000, so that the user applies force to the leg downward or in a direction close to the user's body, i.e., backward.

[0350] After the isotonic motion step S1100, while the leg massage unit 1300 is not operating, an isometric motion step (step S1200) is performed to guide the user's force application to the leg to one side (another direction).

[0351] Here, isometric exercise is a movement method that utilizes isometric contraction. It is a compound word composed of the word "Iso" and the word "Metric". Isometric contraction refers to the generation of tension while the length of the muscle fibers remains unchanged (a state in which the therapist or the subject cannot move even though force is being applied).

[0352] The muscle length does not decrease because the external resistance is greater than the tension used to pull the muscle. Therefore, isometric contraction is also known as static contraction.

[0353] Isometric contractions allow for the contraction of local muscles without rotating the joint, and can be performed while the user experiences pain during the contraction. Therefore, they are widely used in the early rehabilitation steps for fractures or muscle strains.

[0354] In one embodiment, during the isometric motion step S1200, while the leg massage unit 1300 is fixed in a specific position, the user can be introduced by the audio output unit 1440 of the massage device 1000, so that the user applies force to the leg upward or in a direction away from the user's body, i.e., forward.

[0355] For the isotonic motion step S1100 and isometric motion step S1200 of the massage method using PNF stretching in an embodiment of the present invention having the steps described above, the same steps are performed sequentially on one side (left leg) and the other side (right leg) of the user using the first leg massage unit 1310 and the second leg massage unit 1330 of the massage device 1000, and then the next step is performed, so that stretching can be provided to both the left and right legs of the user receiving the massage through one cycle of stretching.

[0356] Furthermore, for the isotonic motion step S1100 and isometric motion step S1200 of the massage method using PNF stretching in an embodiment of the present invention having the steps described above, the foot massage module of the leg massage unit 1300 (not shown in the figures for ease of explanation) used for massaging the sole of the foot can be stopped before the user's leg is fixed using the airbag of the leg massage unit 1300 (not shown in the figures for ease of explanation).

[0357] The massage method using PNF stretching according to one embodiment of the present invention, which has the steps described above, further includes the following steps: during the execution of each massage step, a motion detection step (not shown in the drawings) is performed by using a detection device such as the sensor unit 1410 of the massage device to detect and monitor the actions of the user receiving the massage, and then updating the setting value of the massage device 1000 of the massage mode currently provided to the user.

[0358] from Figure 26 The specific motion methods of isotonic motion and isometric motion of this utility model will be described later.

[0359] For the massage method utilizing PNF stretching according to an embodiment of the present invention having the steps described above, by training to promote or inhibit the response of the neuromuscular mechanism in conjunction with inducing isotonic and isometric contractions of each muscle, it can provide the effects of improving muscle strength, balanced muscle development, and improving joint stability and range of motion.

[0360] Furthermore, according to one aspect of the present invention, when flexibility is increased through such stretching, it can provide a positive effect that can reduce the risk of injury.

[0361] Figure 26 It is used for more detailed explanation. Figure 25 A flowchart of a massage method utilizing PNF stretching according to an embodiment of this utility model.

[0362] Reference Figure 26 According to an embodiment of the present invention, the massage method using PNF stretching firstly performs a leg-lowering step (step S1110) to guide the user to apply force downwards to the leg while the leg massage unit 1300 is rotating upwards.

[0363] In one embodiment, during the leg-lowering step S1110, the user's leg can be fixed using the airbag of the leg massage unit 1300, and the user is guided to apply force to the leg while the leg massage unit 1300 is rotating upward.

[0364] With the leg massage unit 1300 fixed in a specific position, a leg lifting step (step S1210) is performed to guide the user to apply force upwards to the leg.

[0365] In one embodiment, in the leg lifting step S1210, after the leg massage unit 1300 is fixed in a specific position, the user can be guided to apply force upwards to the leg while the user's leg is fixed using the airbag of the leg massage unit 1300.

[0366] At this time, in the leg lifting step S1210, after the height of the user's leg that is not exerting force can be fixed to a specific position by using the leg massage unit 1300, the leg that is not exerting force can be moved downward when the user exerts force on the leg.

[0367] With the leg massage unit 1300 extended forward (stretched), a leg pulling step (step S1120) is performed to guide the user to apply force to the leg backward.

[0368] In one embodiment, during the leg pulling step S1120, the user's leg can be fixed using the airbag of the leg massage unit 1300, and the user can be guided to apply force to the leg while the leg massage unit 1300 is moved forward.

[0369] With the leg massage unit 1300 fixed in a specific position, a leg pushing step (step S1220) is performed to guide the user to apply force to the leg forward.

[0370] In one embodiment, in the leg pushing step S1220, after the leg massage unit 1300 is fixed in a specific position, the user is guided to apply force to the leg forward while the user's leg is fixed by the airbag of the leg massage unit 1300.

[0371] Regarding the massage method utilizing PNF stretching according to an embodiment of the present invention, which has the steps described above, such as Figure 26 As shown, the following steps can be executed alternately: the leg lowering step S1110 and the leg pulling step S1120, which constitute the isotonic motion step S1100; and the leg lifting step S1210 and the leg pushing step S1220, which constitute the isometric motion step S1200.

[0372] exist Figure 27 In China, Figure 26 The more specific methods of the leg-lowering step S1110, leg-raising step S1210, leg-pulling step S1120, and leg-pushing step S1220 will be described later.

[0373] In addition, for the massage method using PNF stretching according to one embodiment of the present invention having the steps described above, after the leg pushing step S1220, it may also include the leg lifting step, the leg lowering step, and the leg pulling step, which will be described later.

[0374] Figure 27 It is used for more detailed explanation. Figure 26 A flowchart of a massage method utilizing PNF stretching according to an embodiment of this utility model.

[0375] Reference Figure 27 First, such as Figure 28 Part (a) shows ( Figure 28 In this context, T represents the direction in which the user applies force. Figure 28 (The arrow B in the figure indicates the direction of movement of the leg massage unit 1300 or 2000.) The leg lowering step S1110 is a preparatory start step before performing this massage step (not shown in the figure for ease of explanation). In this step, the massage device 1000 is driven to a back angle of 250% and a left leg angle of 50% as the starting position for the leg lowering action. Then, the roller device for massaging the sole of the foot, i.e., the foot massage module, is activated. The user is then guided by the following words: (Knee bending action! This is a stretching action that applies force in the opposite direction to the direction of the moving leg. Bend your left knee! From now on, apply force as if bending your left knee during my count to five.)

[0376] If the preparation steps are completed, the first isotonic upward step S1111 is executed. In the first isotonic upward step S1111, after stopping the drive of the foot massage module, the user's feet, insteps, heels and calves are fixed by using airbags, and the leg massage unit 1300 is moved upward to the first position (the leg angle is increased from 50% to 70%). At the same time, guiding count words (one! two! three! four! five!) are introduced to guide the user to apply force to the legs.

[0377] If the first isotonic upward step S1111 is completed according to the guide, the air injected into the airbag is expelled, and the foot massage module is activated and the guiding words are introduced (Please bend your left knee again! Apply force as if bending your left knee).

[0378] The user's feet, insteps, heels, and calves are secured again using airbags. After stopping the foot massage module, preparation begins for the second isotonic upward step S1112, which will be the next step.

[0379] Perform the second isotonic upward step S1112, in which the leg massage unit 1300 is moved upward to a second position (the leg angle is increased from 70% to 80%), the second position being higher than the first position, and at the same time, guiding count words (one! two! three! four! five!) are introduced to guide the user to apply force to the legs.

[0380] If the second isotonic upward step S1112 is completed according to the guidance, the air injected into the airbag is expelled, and the foot massage module is activated and the guiding words are introduced (Please do it again, bend your left knee! This time, adjust your breathing while applying force. From now on, slowly inhale and hold your breath. Apply force as if bending your left knee.).

[0381] The user's feet, insteps, heels, and calves are secured again using airbags. After the foot massage module is stopped, preparations are made for the third isotonic upward step S1113, which will be the next step.

[0382] The third isotonic upward step S1113 is performed, in which the leg massage unit 1300 is moved upward to a third position (the leg angle is increased from 250% to 100%), which is higher than the second position. At the same time, guiding count words (one! two! three! four! five!) are introduced to guide the user to apply force to the legs.

[0383] If the third isometric upward step S1113 is completed, the air injected into the airbag is expelled, and the massage device 1000 is driven to minimize the leg angle, thereby restoring the user's posture.

[0384] For ease of explanation, the leg-lowering step S1110, which has the steps described above, is explained with reference to the left leg. However, the same method can be applied to the right leg, and its explanation is omitted to avoid repetition.

[0385] like Figure 28 As shown in part (f), the leg-lowering step S1110, which has the steps described above, can be composed of a longer leg-lowering step.

[0386] The "Leg Lowering" step is a preparatory step before performing this massage step (not shown in the accompanying drawings for ease of explanation). In this step, the massage device 1000 is driven to a back angle of 250% and a left leg angle of 0%, which is the starting position for the "Leg Lowering" movement. Then, the foot massage module is activated, followed by the guiding words (Leg Lowering Movement! This is the movement of slowly lowering and stretching the leg downwards. Lower the left leg! From now on, while I count to ten, apply pressure to the left leg and slowly lower it downwards.).

[0387] If the preparation steps are completed, the foot massage module is stopped, and the user's feet, insteps, heels, and calves are then secured using airbags. The leg massage unit 1300 is then rotated upwards to the first position (leg angle increased from 0% to 100%). Then, guiding counts (one! two! three! four! five! six! seven! eight! nine! ten!) are introduced to encourage the user to apply pressure to the legs.

[0388] Once all steps are complete, the air injected into the airbag is expelled, and the massage device 1000 is driven to minimize the leg angle, thereby restoring the user's posture.

[0389] For ease of explanation, the steps for lowering the leg with the steps described above are explained using the left leg as a reference. However, the same principle applies to the right leg, and its explanation is omitted to avoid repetition.

[0390] Next, as Figure 28 The leg-lifting step S1210 shown in section (b) is a preparatory step before performing this massage step (not shown in the accompanying drawings for ease of explanation). In this step, the massage device 1000 is driven to a back angle of 250% and a left leg angle of 250% as the starting position for the leg-lifting action. Then, the foot massage module is activated, followed by the guiding words (Stretch your knee and hold the movement! This is a stretching action that lifts the fixed leg upward and holds it with force. Apply force and hold it like stretching your left knee.).

[0391] Once the preparation steps are complete, the foot massage module is stopped. Then, airbags are used to secure the user's feet, insteps, heels, and calves. Guided counting words (one! two! three! four! five!) are introduced to encourage the user to apply pressure to their legs.

[0392] Expel the air injected into the airbag and rotate the leg massage unit 1300 upwards to the first position (leg angle increased from 250% to 90%), then activate the foot massage module, followed by the guiding words (Stretch your knee again and hold! Apply force and hold as if stretching your left knee.).

[0393] After stopping the foot massage module, the user's feet, insteps, heels, and calves are secured again using airbags, and guiding counting words (one! two! three! four! five!) are introduced to encourage the user to apply pressure to their legs.

[0394] If the first isometric upward step S1211 is completed according to the guidance, the second isometric upward step S1212 is executed. In the second isometric upward step S1212, the air injected into the airbag is expelled, and the leg massage unit 1300 is rotated upward to the second position (the leg angle is increased from 260% to 100%). The second position is higher than the first position. Then, the foot massage module is activated, followed by guidance for the user to apply force to the leg (One more time, extend your knee again and hold! This time, while applying force, also adjust your breathing. From now on, slowly inhale and hold your breath. Apply force and hold as if extending your left knee.).

[0395] If the second isometric upward step S1212 is completed, the driving of the foot massage module is stopped, and then the user's foot, instep, heel and calf are fixed by the airbag, and guiding count words (one! two! three! four! five!) are introduced to encourage the user to apply force to the legs.

[0396] If the second equal-length upward step S1212 is completed, the air injected into the airbag is expelled, and the massage device 1000 is driven to minimize the leg angle, thereby restoring the user's posture.

[0397] For ease of explanation, the leg lifting step S1210 with the steps described above is explained with the left leg as a reference, but the same applies to the right leg. To avoid repetition, its explanation is omitted.

[0398] like Figure 28 As shown in part (e), the leg lifting step S1210, which has the steps described above, can be composed of a longer leg lifting step.

[0399] The longer leg raise step is a preparatory step before performing this massage step (not shown in the attached diagram for ease of explanation). In this step, the massage device 1000 is driven to a back angle of 250% and a left leg angle of 260% / right leg angle of 60% as the starting position for the longer leg raise movement. Then, the foot massage module is activated, followed by the guiding words (Lift your legs up! This is a stretching movement where you lift your legs up and hold for 10 seconds. Lift your left leg up! From now on, during my count to ten, use your left leg to lift and hold).

[0400] Once the preparation steps are complete, the foot massage module is stopped. Then, airbags are used to hold the user's feet, insteps, heels, and calves in place, and guiding counts (one! two! three! four! five! six! seven! eight! nine! ten!) are introduced to encourage the user to apply pressure to their legs.

[0401] Next, move the leg massage unit 1300 downwards to the first position (the angle of the right leg is raised from 60% to 40%), then expel the air injected into the airbag and drive the foot massage module, and introduce the guiding words (Lift the left leg up again! Apply force to the left leg, lift it up and hold for 10 seconds.).

[0402] After stopping the foot massage module, the airbags are used to re-secure the user's feet, insteps, heels, and calves, and a numbered list is introduced to guide the user to apply pressure to their legs (one! two! three! four! five! six! seven! eight! nine! ten!).

[0403] Next, the leg massage unit 1300 is moved downwards to the second position (the angle of the right leg is raised from 40% to 20%), which is lower than the first position. Then, the air injected into the airbag is expelled and the foot massage module is driven. Instructions for the user to apply pressure to the leg are introduced (One more time, lift the left leg up! Apply pressure to the left leg and lift it up and hold for 10 seconds.).

[0404] If the steps are completed, the foot massage module is stopped, and the user's foot, instep, heel, and calf are fixed in place using airbags. Guided counting words (one! two! three! four! five! six! seven! eight! nine! ten!) are introduced to encourage the user to apply force to the legs, while moving downwards to the third position (the angle of the right leg is raised from 20% to 0%), which is lower than the second position.

[0405] Once all steps are complete, the air injected into the airbag is expelled, and the massage device 1000 is driven to minimize the leg angle, thereby restoring the user's posture.

[0406] For ease of explanation, the left leg is used as a reference, and the steps described above are explained for the longer leg lifting step. However, the same method can be applied to the right leg, and its explanation is omitted to avoid repetition.

[0407] Next, as Figure 28 The leg-pulling step S1120 shown in section (c) is a preparatory step before performing this massage step (not shown in the accompanying drawings for ease of explanation). In this step, the massage device 1000 is driven to a back angle of 250% and a left leg angle of 270% as the starting position for the leg-pulling action. Then, the foot massage module is activated, followed by the guiding words (Leg-pulling action! This is a stretching action that applies a force in the opposite direction to the direction of the moving leg. Pull the left leg! From now on, during my count to five, pull the left thigh toward the side of the body.).

[0408] If the preparation steps are completed, the first isotonic extension step S1121 is executed. In the first isotonic extension step S1121, the driving of the foot massage module is stopped, and then the user's foot, instep, heel and calf are fixed by the airbag. The leg massage unit 1300 is extended forward to the first position (the length of the left leg is extended by 5cm). At the same time, guiding count words (one! two! three! four! five!) are introduced to guide the user to apply force to the leg.

[0409] If the first isotonic extension step S1121 according to the guide is completed, the air injected into the airbag is expelled, and the foot massage module is activated and the guiding words are introduced (Pull the left leg again! Pull the left thigh towards the side of the body.).

[0410] The user's feet, insteps, heels, and calves are secured again using airbags. After the foot massage module is stopped, preparation is made for the second isotonic extension step S1122, which is the next step.

[0411] The second isotonic extension step S1122 is performed, in which the leg massage unit 1300 is extended forward to a second position (the length of the left leg is extended by 5cm). The second position extends forward further than the first position. At the same time, guiding count words (one! two! three! four! five!) are introduced to guide the user to apply force to the leg.

[0412] If the second isotonic extension step S1122 is completed according to the guidance, the air injected into the airbag is expelled, and the foot massage module is activated and the guiding words are introduced (One more time, pull your left leg! This time, adjust your breathing while applying force. From now on, slowly inhale and hold your breath. Pull your left thigh towards your side.).

[0413] The user's feet, insteps, heels, and calves are secured again using airbags, and after the foot massage module is stopped, preparations are made for the third isotonic extension step S1123, which is the next step.

[0414] The third isotonic extension step S1123 is performed, in which the leg massage unit 1300 is extended forward to a third position (the length of the left leg is extended by 5cm). The third position extends further forward than the second position. At the same time, guiding count words (one! two! three! four! five!) are introduced to guide the user to apply force to the leg.

[0415] Once all steps are complete, the air injected into the airbag is expelled, and the massage device 1000 is driven to minimize the leg angle, thereby restoring the user's posture.

[0416] For ease of explanation, the leg pulling step S1120 with the steps described above is described with reference to the left leg, but the same applies to the right leg. To avoid repetition, the description is omitted.

[0417] like Figure 29 As shown in part (g), the leg pulling step S1120 having the steps described above can be composed of a longer leg pulling step.

[0418] The longer leg-pulling step is a preparatory step before performing this massage step (not shown in the accompanying drawings for ease of explanation). In this step, the massage device 1000 is driven to a back angle of 250% and a left leg angle of 270% as the starting position for the longer leg-pulling action. Then, the foot massage module is activated, followed by the guiding words (Leg-pulling action! This is a stretching action that applies a force in the opposite direction to the direction of the moving leg. Pull your left leg! From now on, while I count to ten, pull your left leg toward your side.).

[0419] If the preparation steps are completed, the foot massage module is stopped. Then, the user's foot, instep, heel, and calf are fixed with airbags, and the leg massage unit 1300 is extended forward to the first position (the left leg is extended by 15cm). Then, a numbered guide word (one! two! three! four! five! six! seven! eight! nine! ten!) is introduced to guide the user to apply force to the leg.

[0420] Once all steps are complete, the air injected into the airbag is expelled, and the massage device 1000 is driven to minimize the leg angle, thereby restoring the user's posture.

[0421] For ease of explanation, the longer leg pulling steps described above are explained using the left leg as a reference. However, the same applies to the right leg, and its explanation is omitted to avoid repetition.

[0422] Secondly, such as Figure 28 The leg-pushing step S1220 shown in section (d) is a preparatory step before performing this massage step (not shown in the accompanying drawings for ease of explanation). In this step, the massage device 1000 is driven to a back angle of 250% and a left leg angle of 270% as the starting position for the leg-pushing action. Then, the foot massage module is activated, followed by the guiding words (Push your knee and hold! This is a stretching action that applies force to the fixed leg and pushes it to hold. Push your left leg and hold! From now on, apply force to your left leg during my count to five, and push and hold with your foot.).

[0423] If the preparation steps are completed, the first equal-length extension step S1221 is executed. In the first equal-length extension step S1221, the driving of the foot massage module is stopped, and then the user's foot, instep, heel and calf are fixed by the airbag. The leg massage unit 1300 is extended forward to the first position (the length of the left leg is extended by 5cm). At the same time, guiding count words (one! two! three! four! five!) are introduced to encourage the user to apply force to the leg.

[0424] Next, after activating the foot massage module, the guiding words are introduced (Push your left leg again and hold! Apply pressure to your left leg and push with your foot and hold.).

[0425] After stopping the foot massage module, the user's feet, insteps, heels, and calves are secured again using airbags, and guiding counting words (one! two! three! four! five!) are introduced to encourage the user to apply pressure to their legs.

[0426] If the first isometric extension step S1211 is completed according to the guidance, the second isometric extension step S1222 is executed. In the second isometric extension step S1222, the air injected into the airbag is expelled, and the leg massage unit 1300 is extended forward to a second position (the length of the left leg is extended by 5 cm). The second position extends further forward than the first position, and the foot massage module is activated. Then, guidance for the user to apply force to the leg is introduced (One more time, push the knee again and hold! This time, while applying force, also adjust your breathing. From now on, slowly inhale and hold your breath. Apply force to the left leg and push with your foot and hold.).

[0427] If the second equal-length extension step S1222 is completed, the driving of the foot massage module is stopped, and then the user's foot, instep, heel and calf are fixed by the airbag, and guiding count words (one! two! three! four! five!) are introduced to encourage the user to apply force to the legs.

[0428] If the second equal-length extension step S1222 is completed, the air injected into the airbag is discharged, and the massage device 1000 is driven to minimize the leg angle, thereby restoring the user's posture.

[0429] For ease of explanation, the leg pushing step S1220 with the steps described above is described with reference to the left leg, but the same applies to the right leg. To avoid repetition, its description is omitted.

[0430] Figure 29 This is a flowchart illustrating a massage method utilizing PNF stretching, which is used to explain another embodiment of the present invention.
