Description

Technical Field

[0001] This utility model relates to a massage device, and more particularly to a massage device having a structure that can adjust and fix the position of the calf massage part to match the user's body condition. Background Technology

[0002] Massage is a medical aid that uses stimulation of specific parts of the body to relieve muscle tension, promote blood circulation, and alleviate fatigue. Recently, due to economic and time constraints, there has been a significant increase in demand for automated massage devices that can be easily used at home. These devices are not simply providing massage, but are increasingly evolving towards offering user-customizable positional adjustments and precise massage functions.

[0003] Traditional leg massagers have limitations in terms of freely adjusting the position and angle of the legs, especially in effectively supporting and massaging the calves. Since each user's calf length, body shape, and leg angle are different, it's difficult to achieve the best massage effect without adjusting the calf position or making precise adjustments. For example, when massaging the calves, it's difficult to fix the calf in the appropriate position or support it at a specific angle according to the user's bending angle, resulting in the inability to fully realize the massage effect.

[0004] Furthermore, the organic connection between the legs and hip joints is crucial, but previous massage devices lacked this connection function. Therefore, users could not naturally move their hip joints while comfortably massaging their calves. Hip joint movement helps improve lower body flexibility, relieves tension in the calf and thigh muscles, and the natural adjustment of hip joint position and movement plays an important role in calf massage. However, previous devices lacked mechanisms for precisely adjusting the angle and position of the legs, including the hip joint, limiting the ability of users to achieve optimal massage results at specific angles.

[0005] Therefore, there is a need for a new type of massage device with a structure that can smoothly move the lower leg and fix it when necessary, while also being correlated with hip joint movement. A technological solution is needed that allows users to maximize the massage effect in optimal posture and angle by organically adjusting the position of the hip joint and lower leg. Utility Model Content

[0006] Problems to be solved by utility models

[0007] The purpose of this invention is to precisely adjust the position of the calf massage part to a user-customized shape and fix it stably, so that the calf and hip joint can perform soft movements and maximize the stretching and massage effect of the hip joint.

For example, the massage device 100 can receive any commands, but is not limited to, regarding the selection of massage module, massage mode, massage intensity, massage time, massage area, position and movement of the body massage unit 1000, on / off power supply of the massage device 100, whether to activate the heating function, and audio source playback.

[0108] As an optional embodiment, the user input unit 1400 may have various buttons in the form of hot keys and / or option buttons for selecting, canceling, or inputting execution directions, depending on preset user settings or its own preset functions.

[0109] The user input unit 1400 can be implemented using a keyboard, dome switch, touchpad (static / electrostatic), rotary switch, etc., but is not limited to these. Alternatively, the user input unit 1400 can acquire commands based on the user's voice using voice recognition technology.

[0110] According to one embodiment of the present invention, the user input unit 1400 may include a display for displaying the operating status of the massage device 100 or the user's current state. In this case, the display may include at least one of a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT LCD), an organic light-emitting diode (OLED), a flexible display, and a 3D display, but is not limited thereto.

[0111] The audio output module 1500 is capable of providing audio output to the user in any form. For example, the audio output module 1500 can provide brain stimulation to the user by outputting the optimal sound source and / or binaural beats for the massage mode provided by the massage device 100. The audio output module 1500 can output audio signals received via a network (not shown) or stored in internal / external storage media (not shown).

[0112] For example, the audio output module 1500 can output audio sources controlled by the user terminal via a network connection (e.g., Bluetooth connection). Additionally, the audio output module 1500 can output any form of sound signal generated in association with the operation of the massage device 100.

[0113] According to an embodiment of the present invention, a massage device 100 may include a network connection unit 1600. The network connection unit 1600 can communicate with modules inside the massage device 100, external massage devices, and / or user terminals via any type of network.

[0114] The network connection unit 1600 may include a wired / wireless connection module for connecting to a network. Wireless connection technologies may include, for example, Wireless LAN (WLAN) (Wi-Fi), Wireless Broadband (Wibro), World Interoperability for Microwave Access (WiMAX), High Speed ​​Downlink Packet Access (HSDPA), etc.

[0115] Wired connection technologies such as Digital Subscriber Line (xDSL), Fiber to the Home (FTTH), and Power Line Communication (PLC) can be used. Additionally, the network connection unit 1600 may include a short-range communication module capable of sending and receiving data with any nearby device / terminal. Examples of short-range communication technologies include Bluetooth, Radio Frequency Identification (RFID), Infrared Data Association (IrDA), Ultra Wideband (UWB), and ZigBee, but are not limited to these.

[0116] As described above, a massage device 100 according to an embodiment of the present invention may include a massage module 1700. That is, the massage module 1700 is a structure that provides mechanical stimulation to the user, and the massage module 1700 can move along the main frame 1100.

[0117] A massage device 100 according to an embodiment of the present invention may include a main frame 1100. For example... Figures 1 to 3 The main frame 1100 can provide a movable path for the massage module 1700.

[0118] The control unit 1200 can control the movement of the massage module 1700 to apply mechanical stimulation to the user to provide a massage.

[0119] The control unit 1200 can move the massage module 1700 along the X, Y, and Z axes. The control unit 1200 can also move the massage ball forward or backward along the X, Y, and Z axes. Alternatively, the control unit 1200 can rotate the massage ball around the X, Y, and Z axes.

[0120] A massage device 100 according to an embodiment of the present invention may include a sensor unit 1800. In this case, the sensor unit 1800 may include at least one sensor. For example, the sensor unit 1800 may include a touch sensor, a pressure sensor, an infrared sensor, an LED sensor, a light sensor, a Hall sensor, an electrostatic sensor, etc., but is not limited thereto.

[0121] The sensor unit 1800 can be used to acquire various types of information. For example, the sensor unit 1800 can be used to identify a user. That is, it can acquire information such as whether the user is seated, the user's body type, and whether the user has any physical abnormalities. As another example, the sensor unit 1800 can be used to acquire biometric information. That is, it can acquire fingerprint information, facial information, voice information, iris information, weight information, electrocardiogram information, body composition information, etc., but is not limited to these, and can include various types of biometric information.

[0122] As an optional embodiment, the massage device 100 can sense the contact area and / or contact position with the user through the sensor unit 1800.

[0123] In addition, the massage device 100 can obtain the user's shoulder position information through the sensor unit 1800.

[0124] Furthermore, the massage device 100 can provide personalized massage based on the acquired information. For example, when the massage device 100 provides a shoulder massage, it identifies the user's shoulder position based on the information acquired by the sensor unit 1800, and can provide a shoulder massage to the user based on the identification result.

[0125] The leg massage unit 2000 can be configured to massage the user's legs. The leg massage unit 2000 may have a leg-accommodating space for accommodating the user's legs. (See reference) Figure 1 and Figure 4 Multiple leg massage units 2000 can be provided, and each of the multiple leg massage units 2000A and 2000B can accommodate the user's right foot and left foot respectively.

[0126] Specifically, the multiple leg massage units 2000A and 2000B may include a foot massage unit 2200 and a calf massage unit 2100, respectively, and can be inserted into, placed in and accommodate the user's right foot and left foot.

[0127] Figure 4This is a diagram illustrating the driving method of a massage device according to an embodiment of the present invention.

[0128] Reference Figure 4 Multiple leg massage units 2000A and 2000B can receive electrical signals from the control unit 1200 to be driven independently.

[0129] Multiple leg massage units 2000A and 2000B are optionally rotatably connected to the main frame 1100.

[0130] The power generated in the hinge drive unit 2001, which will be described later, is transmitted to the support plate 2300. The leg massage unit 2000 hinges (or rotates) in a clockwise and / or counterclockwise direction with reference to the rotation center axis AX1 preset on the main frame 1100, thereby adjusting the leg angle.

[0131] Reference Figure 2 , Figure 5 of (a), Figure 5 (b) The hinge drive unit 2001 can be respectively installed on multiple leg massage units 2000A and 2000B.

[0132] Therefore, as Figure 4 As shown, various modifications can be implemented, such as adjusting the leg angle by rotating only one of the multiple leg massage units 2000A and 2000B relative to the main frame 1100, or adjusting the leg angle by making the multiple leg massage units 2000A and 2000B form the same angle relative to the main frame 1100.

[0133] Figure 5 (a) and Figure 5 (b) is a diagram showing the movement of the foot massage unit and the calf massage unit while the leg massage unit is rotated according to an embodiment of the present invention.

[0134] First refer to Figure 5 (a) and Figure 5 (b) will be used to briefly describe the drive mechanism of the leg massage part of this utility model.

[0135] According to an embodiment of the present invention, the leg massage unit 2000 can rotate relative to the main frame 1100 (specifically the seat frame 1120) by the power generated by the hinge drive unit 2001. That is, by taking the longitudinal central axis of the leg massage unit 2000 (specifically the shaft 2110) as the rotation center axis AX1, the leg massage unit 2000 can rotate relative to the seat frame 1120 by a preset angle.

[0136] Reference Figure 5 (a) and Figure 5(b) According to an embodiment of the present invention, the leg massage unit 2000 is configured to rotate relative to the main frame 1100 (particularly the seat frame 1120) by means of the power generated by the hinge drive unit 2001. Specifically, the leg massage unit 2000 can form a rotation center axis AX1 with reference to the longitudinal central axis of the axis 2110 and rotate relative to the seat frame 1120 by a preset angle.

[0137] In addition, such as Figure 5 (a) and Figure 5 As shown in (b), with the leg massage unit 2000 rotated relative to the seat frame 1120, the foot massage unit 2200 for inserting the user's feet and the calf massage unit 2100 for preventing the lower legs from touching can move on the support plate 2300, thus providing leg length adjustment and stretching functions to match the leg length of the user seated in the massage device 100. The specific working principle associated with this will be explained in more detail later.

[0138] Figure 6 The diagram shows the leg massage section of the massage device according to the present invention, and an enlarged view of the portion where the connecting frame contacts the calf massage section frame. Figure 7 (a) and Figure 7 (b) is a diagram showing the initial state of the leg massage part and the lowered state of the foot massage part frame according to the present invention.

[0139] Reference Figure 6 and Figure 7 (a) and Figure 7 (b) will provide a detailed description of each component of the leg massage unit 2000 according to the present invention.

[0140] The leg massage unit 2000 according to this utility model may include a calf massage unit 2100 (see reference). Figure 5 ), foot massage part 2200, support plate 2300, foot massage part frame 2400, connecting frame 2500, calf massage part frame 2600, actuator 2700.

[0141] The calf massage unit 2100 is fixedly attached to the front of the calf massage unit frame 2600. Therefore, when the calf massage unit frame 2600 moves up and down along the support plate 2300, the calf massage unit 2100 will also move together.

[0142] like Figure 5 (a) and Figure 5 As shown in (b), the leg massage unit 2000 is configured to rotate relative to the main frame 1100 (particularly the seat frame 1120) by the power generated by the hinge drive unit 2001. A rotation center axis AX1 is formed with reference to the longitudinal center axis of the axis 2110 (see reference). Figure 4 The leg massage unit 2000 can rotate at a preset angle relative to the seat frame 1120.

[0143] Therefore, the calf massage unit 2100 can adjust the rotation angle relative to the seat frame to match the user's body shape or leg length, providing a suitable calf massage angle for the user sitting on the massage device.

[0144] The calf massage unit 2100 has a ball massage unit or a roller massage unit at the calf area, which can provide various massage methods. In particular, when the calf massage unit frame 2600 is fixed in front of the calf massage unit frame 2600 and moves up and down with the support plate 2300, the calf massage unit 2100 still moves along the same trajectory, so that it can be aligned with the user's desired position for calf massage.

[0145] The foot massage unit 2200, as a component designed for effectively massaging the user's feet in this invention, is fixed to the foot massage unit frame 2400. Since the foot massage unit 2200 may include a ball massage unit or a roller massage unit 2210, it can provide concentrated stimulation to the user's soles and surrounding areas by providing various massage rotations.

[0146] The foot massage unit 2200, as a component of this invention for massaging the user's feet, is fixed to the foot massage unit frame 2400. The foot massage unit 2200 may include various components to provide a massage effect tailored to the user's soles, specifically implemented using components such as ball massage units or roller massage units. Thus, a structure that effectively stimulates the soles of the feet is provided.

[0147] The support plate 2300 extends in the height direction of the leg massage unit 2000 and is designed to guide the calf massage unit frame 2600 and the connecting frame 2500 within the same track structure. This efficiently raises and lowers the leg massage unit 2000 and stably supports it. At the upper end of the support plate 2300, the shaft 2110 (see reference...) Figure 5 The support plate 2300 is combined with the shaft housing 2120 so that the support plate 2300 can rotate about the shaft 2110. The support plate 2300 rotates by the power generated by the hinge drive unit 2001, so the leg massage unit 2000 as a whole can rotate relative to the main frame 1100.

[0148] The support plate 2300 can be composed of a first support plate 2300A and a second support plate 2300B disposed on both sides. Each support plate 2300A and 2300B can have a guide groove 2310 formed thereon, which supports the independent movement of the calf massage part frame 2600 and the connecting frame 2500. The guide groove 2310 may include a first guide groove 2311 and a second guide groove 2312 formed at different positions on the support plate 2300.

[0149] The first support plate 2300A and the second support plate 2300B may respectively form a first guide groove 2311 that opens forward and a second guide groove 2312 that opens inward. The first guide groove 2311 guides the calf massage frame 2600 to move vertically up and down along the support plate 2300 by providing a path for the calf massage frame 2600 to move up and down. The second guide groove 2312 serves as a dedicated moving path for the connecting frame 2500, allowing it to move up and down while the connecting frame 2500 is stably attached to the support plate 2300.

[0150] Furthermore, each guide groove 2311, 2312 extends along the length of the support plate 2300, designed to allow each frame to move smoothly along a predetermined path. The dual guide groove structure described above supports the stability and accurate position control of the leg massage unit 2000 by enabling independent movement of the calf massage unit frame 2600 and the connecting frame 2500.

[0151] Additionally, a first fixing frame 2320 (see reference) can be configured between the first support plate 2300A and the second support plate 2300B. Figure 8 The first support plate 2300A and the second support plate 2300B are laterally connected by the first fixed frame 2320 to form an integral structure. The first fixed frame 2320 prevents the frame from misaligning or swaying during lifting by firmly connecting the first support plate 2300A and the second support plate 2300B.

[0152] A foot massage unit frame 2400 is located below a support plate 2300, and a foot massage unit 2200 is mounted on the foot massage unit frame 2400. The foot massage unit frame 2400 supports the foot massage unit 2200 and can be raised and lowered via its connection structure with the support plate 2300. An actuator 2700 is connected between the foot massage unit frame 2400 and the support plate 2300, and moves the foot massage unit frame 2400 up and down along the support plate 2300 when driven. This configuration allows the position of the foot massage unit 2200 to be adjusted according to the user's leg length to optimize the massage position.

[0153] The control unit 1200 can adjust the position of the foot massage unit frame 2400 relative to the support plate 2300 by driving the actuator 2700.

[0154] As described above, the combination structure of the foot massage unit 2200 with the foot massage unit frame 2400, support plate 2300 and actuator 2700 can be adjusted according to the leg length, so that the foot massage unit 2200 can be stably installed in the massage device.

[0155] The foot massage unit frame 2400 serves as a structure supporting the foot massage unit 2200, acting as a foundation to ensure the position and stability of the foot massage unit. The foot massage unit frame 2400 has a structure that allows it to move vertically along the support plate 2300 when engaged with it. This vertical movement is achieved through engagement with the actuator 2700, and when the actuator 2700 is connected between the foot massage unit frame 2400 and the support plate 2300 and is driven, the foot massage unit frame 2400 can be raised and lowered.

[0156] Specifically, the foot massage unit frame 2400 is designed to stably support the foot massage unit 2200 and is slidably attached to the support plate 2300. This attachment structure allows the foot massage unit 2200 to be adjusted in a user-customized position and enables the foot massage unit 2200 to be effectively set according to various needs such as leg length adjustment.

[0157] The connecting frame 2500 supports the calf massage unit frame 2600 from the lower part of the leg massage unit 2000 and supports position adjustment. The connecting frame 2500 consists of a first connecting frame 2500A and a second connecting frame 2500B disposed on both sides. These two connecting frames 2500A and 2500B are laterally connected by a fixing frame 2510 to form an integral structure. The fixing frame 2510 prevents the frame from shifting or wobbling during lifting by firmly connecting the first and second connecting frames 2500A and 2500B.

[0158] The lower ends of the first and second connecting frames 2500A and 2500B are combined with the foot massage part frame 2400. In this combined state, they can move up and down along the second guide groove 2312 formed in the support plate 2300.

[0159] The calf massage frame 2600 is designed to be integrated with the calf massage unit 2100 and to move up and down along the first guide groove 2311 of the support plate 2300. It can be installed inside the leg massage unit 2000. The calf massage frame 2600 is configured to adjust the position of the calf massage unit 2100 according to the user's leg length or position, and is configured to be mounted on the support plate 2300 so as to move up and down stably.

[0160] The calf massage unit frame 2600 is manufactured in a robust manner so that it can smoothly engage with the guide groove of the support plate while maintaining its strength, and is provided with a mounting part 2610 for fixing the calf massage unit 2100.

[0161] In its initial state, the calf massage frame 2600 is tightly attached to and located on the upper side of the connecting frame 2500, contacting the upper part of the connecting frame 2500 for stable support. The calf massage frame 2600 is designed to be pushed upwards along with the connecting frame 2500 when it rises, allowing it to move together with the frame when needed.

[0162] For independent operation, the calf massage unit frame 2600 and the connecting frame 2500 can be separated from each other by the operation of the actuator 2700. In this case, the calf massage unit frame 2600 can be independently raised and lowered along the first guide groove 2311 of the support plate 2300, separate from the connecting frame 2500.

[0163] The actuator 2700, as a telescopic device, is positioned between the support plate 2300 and the foot massage unit frame 2400, serving to raise and lower the foot massage unit frame 2400 with the support plate 2300 as a reference. The lower end of the actuator 2700 can be fixed to the foot massage unit frame 2400, and the upper end can be connected to the upper end of the support plate 2300. Thus, the actuator 2700 can adjust the position of the foot massage unit frame 2400 via the support plate 2300.

[0164] The actuator 2700 moves the foot massage unit frame 2400 up and down by extending and retracting, resulting in the entire structure, including the connecting frame 2500, being able to descend relative to the support plate 2300. Thus, the foot massage unit 2200 can be moved away from the user while the calf massage unit 2100 remains in a fixed position.

[0165] The lower end of the first tension spring 2810 is fixed to the back of the first fixed frame 2320 of the support plate 2300, and its upper end is connected to the lower part of the calf massage part frame 2600. The first tension spring 2810 pulls the calf massage part frame 2600 downward, causing the pawl 2910 to engage with the rack 2920 and remain locked, thereby maintaining a stable and fixed state. In addition, it also performs the function of pulling the calf massage part frame 2600 downward when the pawl 2910 reaches the uppermost end of the rack 2920, so that the pawl 2910 returns to its initial position.

[0166] Figure 8 This is a diagram showing the pawl and rack structure used for adjusting the position of the calf massager frame 2600 in the leg massager according to the present invention. Figure 9 This diagram shows the initial rotational state of the pawl in contact with the rack. Figure 10 This is a diagram showing the state of the pawl being pulled by the second tension spring.

[0167] Reference Figures 8 to 10 The locking structure of this invention includes a fixing part that can fix the calf massage part frame 2600 at different heights. The fixing part may include a first fixing part that engages with the calf massage part frame 2600 and a second fixing part disposed on a support plate 2300. According to an embodiment, the first fixing part may be formed by a pawl 2910, and the second fixing part may be formed by a rack 2920. However, it is not limited to this; the first and second fixing parts may be made of any components that can engage and disengage with each other.

[0168] According to an embodiment of the present invention, the locking structure is formed by the engagement of a pawl 2910 and a rack 2920, which can be adjusted by a second tension spring 2811. The second tension spring 2811 will be described first, followed by the description of the engagement structure of the pawl 2910 and the rack 2920.

[0169] The second tension spring 2811, as a structural element connecting the lower end of the pawl 2910 to a specific position on the calf massage unit frame 2600, provides tension to pull the pawl 2910 toward the rack 2920. The second tension spring 2811 guides the rotation of the pawl 2910 so that the pawl 2910 can stably engage with the rack 2920, thereby fixing the position of the calf massage unit frame 2600.

[0170] One end of the second tension spring 2811 is connected to the second hinge shaft 2912 located at the lower end of the pawl 2910 to guide the rotation of the pawl 2910. The other end is fixed to the spring connecting shaft 2811a located on the calf massage part frame 2600. When the pawl 2910 is engaged with or disengaged from the rack 2920, this configuration naturally utilizes the tension of the second tension spring 2811 to move the pawl 2910 in the appropriate direction of rotation.

[0171] When the pawl 2910 rotates to engage with or disengage from the rack 2920, the second tension spring 2811 provides a stable pulling force, thereby securing the calf massage unit frame 2600 in the desired position. This structure constitutes an effective locking mechanism that allows for adjustment and fixation of the calf massage unit 2100's position even without a separate additional motor.

[0172] The pawl 2910 is a component used to fix the position of the calf massage unit 2100. The pawl 2910 is rotatably connected to the calf massage unit frame 2600 via a first hinge axis 2911, which serves as the rotation axis of the pawl 2910. The pawl 2910 can rotate up and down around the first hinge axis 2911.

[0173] The lower part of the pawl 2910 is connected to a second hinge shaft 2912, which is connected to a second tension spring 2811 that adjusts the rotation direction and position of the pawl 2910. The second tension spring 2811 is connected between the second hinge shaft 2912 and a spring connecting shaft 2811a provided on the calf massage part frame 2600 to apply a certain tension to the pawl 2910. This tension guides the pawl 2910 to rotate in a specific direction, which can maintain the engagement between the pawl 2910 and the rack 2920 or disengage the pawl 2910 from the rack 2920.

[0174] Specifically, when the second hinge axis 2912 is closer to the rack 2920 than the first hinge axis 2911, the tension of the second tension spring 2811 pulls the pawl 2910 towards the rack 2920 and fixes it in place. This structure, through the engagement of the pawl 2910 and the rack 2920, stabilizes the position of the calf massage frame 2600. Conversely, when the second hinge axis 2912 is farther from the rack 2920 than the first hinge axis 2911, the change in the direction of tension causes the pawl 2910 to rotate away from the rack 2920.

[0175] As described above, the rotation and position fixation of the pawl 2910 can be determined by the relative positions of the first hinge shaft 2911, the second hinge shaft 2912 and the spring connecting shaft 2811a and the tension of the second tension spring 2811. Thus, the position of the calf massage part frame 2600 can be accurately adjusted and fixed.

[0176] The rack 2920, as an important fixing structural element of this utility model, serves to maintain the position of the calf massage part 2100 or restrict its movement. The rack 2920 includes structures that are respectively coupled to the support plates 2300 (specifically, the first support plate 2300A and the second support plate 2300B). The rack 2920 can be inserted into and fixed in the second guide grooves 2312 of each support plate 2300A, 2300B (see reference). Figure 9 This structure means that the rack 2920 can be configured to be combined with the first support plate 2300A and the second support plate 2300B respectively.

[0177] Each rack 2920 may include multiple protrusions 2921 to be engaged by a pawl 2910. According to an embodiment, the protrusions 2921 may be formed in a serrated shape. However, it is not limited to this and may be formed in any protruding shape.

[0178] When the protrusion 2921 of the rack 2920 engages the lower end of the pawl 2910, the position of the pawl 2910 is fixed by the rack 2920. The protrusion 2921 can be configured in various intervals and shapes, so that the pawl 2910 is fixed in a stepped manner, thereby enabling fine position adjustment of the calf massage unit 2100.

[0179] The rack 2920 may include various protruding structures for fixing and initializing the position of the pawl 2910. According to an embodiment, the rack 2920 may include: a plurality of locking protrusions 2921A for locking the pawl 2910; and an upper protrusion 2921B formed on the upper side of these locking protrusions 2921A. The plurality of locking protrusions 2921A serve to fix the position of the calf massage unit 2100 by engaging with the pawl 2910. The upper protrusion 2921B is configured to protrude more than the locking protrusions 2921A, and when the pawl 2910 reaches its upper end, pushes it to the opposite side of the rack 2920 to perform the function of returning to the initial rotational position.

[0180] In this configuration, when the pawl 2910 reaches the upper end of the rack 2920, it is pushed by the upper protrusion 2921B, and the second hinge shaft 2912 rotates further away from the rack 2920 than the first hinge shaft 2911 and returns to its initial rotational position. Thus, the pawl 2910 can naturally return to its original rotational position.

[0181] Figure 11 (a) and even Figure 11 (c) is a diagram illustrating the rising process of the pawl in the locking structure according to the present invention. Figure 12 (a) to Figure 12 (c) is immediately following Figure 11 The diagram illustrates the process of the pawl descending after initializing its rotational position at the upper end. Figure 13 (a) to Figure 13 (b) is immediately following Figure 12 The diagram illustrates the process of the pawl returning to its initial state after descent.

[0182] Reference Figures 11 to 13 First of all Figure 11 The first stop 2930 shown and Figure 13 The second stop 2940 shown will be explained, and then the operation of the locking structure will be explained.

[0183] The first stop 2930 is located on the upper side of the rack 2920, serving to return the pawl 2910 to its initial rotational position and provide support. The first stop 2930 is configured with an inclined shape at its lower end closer to the rack 2920, designed to naturally contact and support the pawl 2910 as it rotates and returns to its initial position. This inclined shape interacts with the back of the pawl 2910 to ensure stable contact.

[0184] The first stop 2930 is manufactured in the form of a plate with a specified thickness, thereby preventing excessive movement of the pawl 2910 by contacting the back of the pawl 2910 and ensuring that it is stably fixed in the accurate position. Even at the moment when the pawl 2910 disengages from the protrusion of the rack 2920 after rotation is completed, this structure helps to stably support the pawl 2910.

[0185] Furthermore, to correspond with the first stop 2930, the back of the pawl 2910 is also configured with an inclined shape, where the lower end is closer to the rack 2920 than the upper end, allowing the two components to mesh tightly with each other. As a result, the pawl 2910 is stably supported on the first stop 2930, thus maintaining its initial rotational position without wobbling.

[0186] The second stop 2940 is located on the lower side of the rack 2920 of this invention, and serves to initialize the pawl 2910 after it descends. The second stop 2940 is fixed at a position adjacent to the rack 2920, and is designed to contact the lower side of the pawl 2910.

[0187] The second stop 2940, as a structural element in this invention for controlling the movement of the pawl 2910 and returning it to its initial position, is located on the lower side of the rack 2920 and operates during the descent of the pawl 2910. According to an embodiment, the second stop 2940 can be formed as a protrusion extending upwards on the plate, and can be engaged with the upper surface of the "∟"-shaped bracket 2941 fixed to the side of the support plate 2300.

[0188] The second stop 2940 is configured with its height lowered in the direction toward the rack 2920, and this inclined surface is designed to naturally correspond when in contact with the lower side of the pawl 2910. The lower side of the pawl 2910 also has a structure that gradually slopes from rear to top, and in interaction with this, the pawl can be properly controlled by engaging with the second stop 2940.

[0189] When the pawl 2910 descends and contacts the second stop 2940, the pawl 2910 is guided by the corresponding inclined surface and pushed towards the rack 2920 side, and is guided back to the initial position. This structure prevents unnecessary rotation or excessive movement by stably controlling the movement of the pawl 2910 and helps to achieve a smooth return to the initial position.

[0190] The following is for reference Figures 11 to 13 The operation of the locking structure of this utility model will be explained in turn.

[0191] Reference Figure 11 (a) to Figure 11 (c) The process by which the pawl 2910 rises from its initial state, passes through the multiple locking protrusions 2921A of the rack 2920, and reaches the upper protrusion 2921B is described below.

[0192] In the initial state, the pawl 2910 is pulled towards the rack 2920 by the tension of the second tension spring 2811 and engages with the lower protrusion 2921A of the rack 2920. At this time, the rotation axis of the pawl 2910 is fixed by the first hinge axis 2911. When the connecting frame 2500 rises, the pawl 2910 rises along each locking protrusion 2921A while being pulled towards the rack 2920 by the tension spring 2912.

[0193] Each time the calf massage unit frame 2600 rises, the pawl 2910 temporarily engages with a specific locking protrusion 2921A to secure the calf massage unit frame 2600. Then, as the connecting frame 2500 rises further, the pawl 2910 rotates and moves to the next locking protrusion 2921A. The direction of rotation of the pawl 2910 is adjusted by the second hinge shaft 2912 and the first hinge shaft 2911, which are connected by a second tension spring 2811. The pawl 2910 repeats the action of engaging with each locking protrusion 2921A, during which the pawl 2910 rises in a stepped manner.

[0194] When the calf massage unit frame 2600 reaches a specific position that matches the user's calf position, the pawl 2910 engages with the locking protrusion 2921A at the corresponding position and temporarily stops. At this time, the first tension spring 2810 exerts a downward pulling force on the calf massage unit frame 2600, so that the pawl 2910 can stably engage with the corresponding specific locking protrusion 2921A and be fixed. This fixed state helps to maintain the stable position of the calf massage unit frame 2600 and provides a customized fixation that matches the user's calf position according to the drive of the massage device.

[0195] Reference Figure 12 (a) to Figure 12The process of the pawl 2910 descending after rising, being pushed by the upper protrusion 2921B and supported by the first stop 2930 is described in (c).

[0196] When the pawl 2910 reaches the upper protrusion 2921B via the additional drive of the massage device, the upward movement of the pawl 2910 is restricted because the upper protrusion 2921B is configured to protrude more than the other locking protrusions 2921A. Therefore, the pawl 2910 stops moving upward further. At the same time, the pawl 2910 is pushed towards the opposite side of the rack 2920 by the pushing action of the upper protrusion 2921B and is stably supported by the first stop 2930 provided on its side.

[0197] In this state, the calf massage unit frame 2600 is pulled downwards by the operation of the first tension spring 2810. Therefore, the calf massage unit frame 2600 descends relative to the support plate 2300, and the pawl 2910 descends relative to the rack 2920 in a state separated from it. This process allows the pawl 2910 to descend without contacting the rack 2920 and without friction while being stably supported.

[0198] Reference Figure 13 (a) and Figure 13 (b) The process by which the pawl 2910 returns to its initial state after descending via the second stop 2940 is described below.

[0199] As the pawl 2910 descends and moves away from the rack 2920, the lower stop 2940 contacts the lower side of the pawl 2910. The second stop 2940 is formed with an inclined structure, causing the pawl 2910 to naturally rotate clockwise during descent, thus returning it to its initial position. The second stop 2940 engages with the upper surface of the "∟"-shaped bracket 2941 fixed to the side of the support plate 2300 to push the pawl 2910 towards the rack 2920, thus initializing it.

[0200] The pawl 2910 moves, rotates, and descends along the inclined surface of the second stop 2940 to its initial state, eventually returning to the lower part of the rack 2920. This structure allows the pawl 2910 to smoothly return to its initial position and change to a state ready for the next drive.

[0201] Figure 14 (a) to Figure 14 (d) is a diagram showing, in sequence, the basic position of the leg massage part according to the present invention, the 40mm fixed position of the lower leg, the position where the foot is lowered after the 40mm fixed position of the lower leg, and the state in which the lower leg is set at the maximum height of 70mm.

[0202] Reference Figure 14 (a) to Figure 14 The following is a detailed description of how the locking structure of the calf massage unit frame 2600 is applied when the leg massage unit 2000 according to the present invention is driven.

[0203] Figure 14 (a) shows the initial state of the leg massage unit 2000 before it is raised by the hinge drive unit 2001. In this state, the calf massage unit frame 2600 is located on the support plate 2300, and the position of the shaft 2110 is higher than that of the calf massage unit frame 2600. This indicates that the calf massage unit frame 2600 is in the drive ready state.

[0204] Figure 14 (b) shows the leg massage unit 2000 raised via the hinge drive unit 2001, with the calf massage unit frame 2600 raised to approximately 40 mm in height. At this point, the pawl 2910 is locked while engaging with the locking protrusion 2921A at a specific position, thus securing the position of the calf massage unit frame 2600. This locking structure helps to stably fix the leg massage unit 2000 to match the user's calf position.

[0205] Figure 14 (c) illustrates the process of the connecting frame 2500, which is coupled to the support plate 2300, descending as the actuator 2700 operates. As the connecting frame 2500 descends, the distance between the foot massage unit 2200 and the calf massage unit frame 2600 increases, guiding a hip joint movement effect. The increased distance between the user's leg and the massage unit provides a stretching effect to the user.

[0206] Figure 14 (d) shows the state where the leg massage unit 2000 has risen again via the hinge drive unit 2001 and the calf massage unit frame 2600 has risen to its maximum height of 70 mm. At this time, compared to the initial state, the support plate 2300 has descended relative to the calf massage unit frame 2600. At this time, the pawl 2910 reaches the upper protrusion 2921B and is restricted from further upward movement. The upper protrusion 2921B protrudes more than the other locking protrusions 2921A, thereby preventing the pawl 2910 from moving upward and stably fixing its position. Afterward, the pawl 2910 descends back to the initial state and completes the subsequent drive preparation.
