The elastic member 1541 may be provided as a variety of members capable of applying elastic force to the pressure plate 1540. As an example, the elastic member 1541 may be provided as a torsion spring. When the elastic member 1541 is provided as a torsion spring, when the pressure plate 1540 rotates, both ends of the torsion spring may contact at least one of the pressure plate 1540 and the center support bracket 1530.

The elastic member 1541 simply allows the user to press against the pressing plate 1540 in situations where the user's body or other objects are not caught between the leg massage unit 1300 or between the leg massage unit 1300 and the body massage unit 1100. It is possible to prevent the pressure plate 1540 from rotating due to contact with the body or other objects.

The pressure plate 1540 may rotate to contact 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 may rotate and come into contact with the sensor 1520.

Referring to (a) of FIG. 18, due to the elastic force of the elastic member 1541, one end of the pressure plate 1540 may be disposed to be spaced apart from the sensor 1520, and the other end may contact the stopper 1531e. It can be. Since elastic force continuously acts on the pressure plate 1540, one end of the pressure plate 1540 may not contact the sensor 1520 if a predetermined external force is not applied for a predetermined time.

Referring to (b) of FIG. 18, while the user's body is sandwiched between the leg massage unit 1300 and/or between the leg massage unit 1300 and the body massage unit 1100, the leg massage unit 1300 and the body massage unit 1300 When at least one of the massage units 1100 rotates, an external force F greater than the elastic force of the elastic member 1541 may be applied to the pressure plate 1540. Additionally, the external force F continues to act on the pressure plate 1540 unless the stuck state is released. In this case, the pressure plate 1540 rotates, and one end may be in contact with the sensor 1520. When the pressure plate 1540 is contacted, the sensor 1520 can transmit the corresponding information to the control unit 1400. When the control unit 1400 receives information from the sensor unit 1520 that the pressure plate 1540 has been contacted, the control unit 1400 operates at least one of the first leg massage unit 1310, the second leg massage unit 1330, and the body massage unit 1100.

Ultimately, the lower leg massage units (2000ab, 2000bb) may move closer to or away from the upper leg massage units (2000aa, 2000ba) as the lead screws (2510a, 2510b) rotate, so that the upper leg massage units (2000aa, 2000ba) and The distance of the lower leg massage units 2000ab and 2000bb may be adjusted, and ultimately the length of the first and second

leg massage units

2000a and 2000b may be adjusted.

Referring to FIG. 21,

guide rails

2211a and 2211b may be formed inside the leg frames 2210a and 2210b. In addition, the first and second leg massage units (2000a, 2000b) include guide rollers (2540a, 2540b) moving along the guide rails (2211a, 2211b) and guide bars (2530a, 2530b) supporting the guide rollers (2540a, 2540b) ) may include. At this time, one end of the

guide bars

2530a and 2530b may be connected to the lower leg massage units 2000ab and 2000bb. Accordingly, as the lead screws 2510a and 2510b rotate, the

guide bars

2530a and 2530b and the

guide wheels

2540a and 2540b may move in the same direction as the lower leg massage units 2000ab and 2000bb.

Meanwhile, the

guide rollers

2540a and 2540b can move along the

guide rails

2211a and 2211b. Accordingly, the

guide rollers

2540a and 2540b can guide the lower leg massage units 2000ab and 2000bb to move in an appropriate direction. Accordingly, while the lower leg massage units 2000ab and 2000bb move, the

leg massage units

2000a and 2000b on both sides may not shake.

Meanwhile, the

guide rails

2211a and 2211b may be formed on an inner portion of the leg frame 2210. Referring to FIG. 21,

guide rails

2211a and 2211b are formed only on a portion of the inside of the leg frame 2210, and a jaw is formed on the remaining portion, which can block the movement of the

guide rollers

2540a and 2540b. As a result, it is possible to block the lower leg massage units (2000ab, 2000bb) from moving beyond the limit point, and prevent the problem of the lower leg massage units (2000ab, 2000bb) completely leaving the upper leg massage units (2000aa, 2000ba). can do.

Meanwhile, in order to more appropriately guide the movement of the guide bars (2530a, 2530b), the leg massage unit 2000 includes guide wheels (2551a, 2551b) and guide wheel brackets that accommodate and support the guide wheels (2551a, 2551b). It may further include (2552a, 2552b). Referring to FIG. 22, at least one guide wheel (2551a, 2551b) may be disposed inside the guide wheel bracket (2552a, 2552b). The outer surfaces of the

guide wheels

2551a and 2551b may be concave inward, and guide

bars

2530a and 2530b may be inserted and positioned to correspond to the concave area. Therefore, when the

guide bars

2530a and 2530b move up and down, the

guide wheels

2551a and 2551b can support the

guide bars

2530a and 2530b so that they do not deviate from the moving path. Ultimately, the guide wheels (2551a, 2551b) support the guide bars (2530a, 2530b) to prevent the guide bars (2530a, 2530b) from shaking while moving, and allow the guide bars (2530a, 2530b) to move in an appropriate direction. You can guide the route. Accordingly, the lower leg massage units 2000ab and 2000bb can also move in an appropriate direction and not be shaken by the

guide bars

2530a and 2530b.

As described above, the first and second

foot massage units

2610 and 2630 include two foot massage modules and one foot massage actuator, but are not limited thereto. For example, each of the first and second foot massage units may include a plurality of foot massage modules (eg, three or more), and each foot massage module may be arranged in a straight line as shown in FIG. 23 . At this time, the straight line may be a line crossing the sole of the foot. Each of the first and second foot massage units includes a single foot massage actuator and can drive all of the plurality of foot massage modules through the single foot massage actuator.

Meanwhile, the foot massage module may have at least one protrusion formed on its surface. Accordingly, the foot massage module can provide massage to the soles of the user's feet by rotating.

Alternatively, the foot massage module may be a roller whose surface is formed in an arc shape. Accordingly, the foot massage module can provide massage to the soles of the user's feet by rotating.

Meanwhile, as an optional embodiment, the foot massage actuator may be equipped with a cam. Therefore, the foot massage unit can provide an acupressure massage to the user's toes using a cam without a rolling massage. Additionally, by mounting a cam on the foot massage actuator, spatial efficiency can be improved compared to the case where the foot massage actuator is provided separately.

Figure 24 is a diagram showing the anti-jamming sensor (S) in the leg massage unit 2000 according to an embodiment of the present invention.

At least one anti-entrapment sensor (S; or safety sensor) at at least one position between the side, rear, and upper leg massage parts (2000aa, 2000ba) of the leg massage part (2000) and the lower leg massage parts (2000ab, 2000bb) ) may be provided. At this time, the anti-entrapment sensor S may be a sensor for recognizing that a part of the user's body is caught around the

leg massage units

2000a and 2000b.

At this time, the anti-jamming sensor S provided may be a capacitive touch sensor, but is not limited thereto.

When the anti-entrapment sensor (S) is attached to the side of the leg massage unit 2000, when the leg massage unit 2000 rotates, a part of the user's body may be detected between the

leg massage units

2000a and 2000b on both sides. You can recognize what's happening. Alternatively, when the leg massage unit 2000 rotates, it may be recognized that a part of the user's body is caught between the leg massage unit 2000 and the body massage unit 1100.

When the anti-jamming sensor (S) is attached to the rear of the leg massage unit 2000, when the leg massage unit 2000 rotates, it can recognize that a part of the user's body is caught in the rear of the leg massage unit 2000. You can.

When the pinch prevention sensor (S) is attached between the upper leg massage portions (2000aa, 2000ba) and the lower leg massage portions (2000ab, 2000bb), the upper leg massage portions (2000aa, 2000ba) and the lower leg massage portions (2000ab, When adjusting the distance of 2000bb), it may be recognized that a part of the user's body is caught between the upper leg massage parts 2000aa and 2000ba and the lower leg massage parts 2000ab and 2000bb.

Therefore, when the user's body is caught in a specific position of the massage device 100 while the leg massage unit 2000 is rotating, the anti-jamming sensor S can recognize this, and the massage device 100 will be stopped accordingly. and safety accidents can be prevented.

Meanwhile, the jamming prevention sensor (S) may be formed to extend to have a length. That is, the jamming prevention sensor S may be a linear sensor.

When the leg massage unit 2000 rotates or the length is adjusted, the human body cannot tell which part of the leg massage unit 2000 will get caught, so when the anti-jamming sensor S is formed to extend in the longitudinal direction. The area that can detect whether the user's body is in contact can be expanded. Accordingly, the user can use the massage device 100 more safely.

As an optional embodiment, the anti-entrapment sensor S may be provided in the upper leg massage parts 2000aa and 2000ba and the lower leg massage parts 2000ab and 2000bb, respectively. At least one anti-jamming sensor (S) may be provided on each side. For example, the jamming prevention sensors S may be provided on both sides of the upper leg massage units 2000aa and 2000ba, respectively, and may be located on the left and right sides of the rear of the upper leg massage units 2000aa and 2000ba, respectively. Additionally, the anti-jamming sensor S may be located between the upper leg massage parts 2000aa and 2000ba and the lower leg massage parts 2000ab and 2000bb. Additionally, anti-jamming sensors S may be provided on both sides of the lower leg massage units 2000ab and 2000bb, respectively.

Accordingly, even if a part of the user's body, such as a leg, gets caught in any adjacent position of the leg massage unit 2000 while the massage device 100 is operating, this can be recognized.

Although not shown in the drawing, the leg massage unit 2000 may further include a sensor for controlling the length of the leg massage unit 2000.

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 setting a limit for adjusting the length of the leg massage unit 2000. Alternatively, the limit sensor may be a sensor for determining the reference position of the leg massage unit 2000. For example, the limit sensor may be a Hall sensor, but is not limited thereto.

By including a limit sensor, the upper leg massage units (2000aa, 2000ba) and the lower leg massage units (2000ab, 2000bb) may not move apart beyond a certain limit, preventing safety accidents, and the lower leg massage units (2000ab, 2000ab, 2000bb) can be prevented from being completely separated from the upper leg massage portions 2000aa and 2000ba.

As another example, the leg massage unit 2000 may include an encoder. Therefore, the distance between the upper leg massage units 2000aa and 2000ba and the lower leg massage units 2000ab and 2000bb can be recognized using an encoder, and the length adjustment limit of the leg massage unit 2000 can be determined accordingly. That is, the distance between the upper leg massage unit (2000aa, 2000ba) and the lower leg massage unit (2000ab, 2000bb) is recognized through the encoder, and when a certain limit is reached, the upper leg massage unit (2000aa, 2000ba) and the lower leg massage unit are The relative movement of (2000ab, 2000bb) can be stopped.

As one embodiment, the

leg massage units

2000a and 2000b may further include a measurement sensor unit for measuring the user's leg length. For example, the measurement sensor unit may include at least one measurement sensor among a first measurement sensor and a second measurement sensor. The first leg massage unit 2000a may include a first measurement sensor that measures the length of one leg, and the second leg massage unit 2000b may include a second measurement sensor that measures the length of the other leg.

Preferably, each measurement sensor uses at least one sensor (or sub-measurement sensor) among the first sensor (or first sub-measurement sensor) and the second sensor (or second sub-measurement sensor) to measure the user's leg length. It can be included.

For example, the first sensor may be a capacitive touch sensor. The first sensor may be used to roughly measure the user's leg length. Accordingly, the user's leg length can be measured through the first sensor, and the length of the

leg massage units

2000a and 2000b can be adjusted to correspond.

The first sensor may recognize that the user's body is in contact and measure the leg length. Accordingly, the first sensor can measure the length of the user's legs depending on whether the user's body is in contact, and based on this, the massage device 100 can adjust the length of the

leg massage units

2000a and 2000b, and the precision is Although it may fall, the length of the

leg massage parts

2000a and 2000b can be quickly and roughly adjusted.

In order to precisely measure the length of the

leg massage units

2000a and 2000b, the

leg massage units

2000a and 2000b according to the present invention may further include a second sensor.

For example, the second sensor may be a photo sensor or a load sensor. The second sensor may be used to precisely measure the user's leg length. Accordingly, the massage device 100 roughly measures the user's leg length using the first sensor, adjusts the length of the

leg massage units

2000a and 2000b to correspond, and then uses the second sensor to measure the user's leg length. The leg length can be precisely measured, and the length of the

leg massage units

2000a and 2000b can be adjusted to correspond.

FIG. 25 is a diagram showing a photo sensor in a leg massage unit according to an embodiment of the present invention, and FIG. 26 is an enlarged view of D of FIG. 25.

Referring to FIGS. 25 and 26 , in one embodiment, the second sensor may be a photo sensor (PS). Preferably, it may be a mechanical photo sensor. In this way, when using the photo sensor (PS), as described above, the user's leg length can be measured more precisely than when only the first sensor is used. In addition, photo sensors (PS) are provided on both leg massage parts, making it possible to precisely measure the length of both legs of the user.

For example, the photo sensor PS may be located below the

leg massage units

2000a and 2000b. Accordingly, the photo sensor (PS) can measure the user's leg length more precisely. That is, referring to FIG. 26, when movement of the

leg massage parts

2000a and 2000b occurs, which are located on the lower sides of the

leg massage parts

2000a and 2000b on both sides of the photo sensor PS, the movement causes the disk The member rotates, and by measuring the degree of light reception that changes due to the rotation of the disk member, it is possible to precisely measure the user's leg length.

However, it is not limited to this, and of course, the user's leg length can be measured by using a different type of photo sensor (PS) or by the principle on which the existing photo sensor (PS) operates.

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

For example, the control unit 1400 of the massage device 100 adjusts the distance between the upper leg massage units 2000aa and 2000ba and the lower leg massage units 2000ab and 2000bb while detecting a load of a preset size on the second sensor. The length of the

leg massage units

2000a and 2000b at the point of application may be recognized as the user's leg length. Accordingly, the massage device 100 finely adjusts the distance between the upper leg massage units 2000aa and 2000ba and the lower leg massage units 2000ab and 2000bb when a preset load of a certain size is applied to the second sensor. The distance between the

leg massage units

2000a and 2000b at that time can be recognized as the user's leg length, and in this case, the length of the

leg massage units

2000a and 2000b can be adjusted to correspond to the user's leg length.

Meanwhile, the first sensor and the second sensor may be located on the lower surfaces of the

leg massage units

2000a and 2000b. Preferably, it may be provided in a position corresponding to the sole of the user's foot. Therefore, the user's leg length can be precisely measured according to changes in the length of the

leg massage units

2000a and 2000b.

Below, the operation method of the above-described massage device 100 will be described in detail.

The method of operating the massage device 100 according to the present invention includes receiving a user input, recognizing physical information about at least a part of the user's body, adjusting the massage device based on the body information, and It may include providing a massage to the user using an adjusted massage device.

FIG. 27 is a diagram illustrating a stretching mode and an exercise mode provided by a massage device according to an embodiment of the present disclosure.

The massage device 1000 may provide a stretching mode for stretching the user's body and a leg rehabilitation mode (or cycle mode) for exercising the user's legs. At this time, the stretching mode may be a mode for stretching at least one of the user's legs, waist, and buttocks (eg, hip area). The cycle mode may be a mode used by users with normal legs to exercise their legs, or a mode used by users with abnormal legs due to various injuries such as knee injuries to rehabilitate their legs.

For example, the stretching modes include iliopsoas stretching mode (or iliopsoas relaxation mode), which stretches the iliopsoas muscle of the leg, hamstring stretching mode (or hamstring relaxation mode), which stretches the hamstrings of the leg, and waist stretching mode (or rolling stretching mode), which stretches the lower back. mode), and a piriformis muscle stretching mode (piriformis muscle relaxation mode) that stretches the piriformis muscle of the buttocks.

Specifically, the controller 1400 may execute each stretching mode and/or cycle mode based on the user's response, or may automatically execute each stretching mode and/or cycle mode. At this time, the user's response may be a response (or signal) for executing the stretching mode and/or the cycle mode.

The controller 1400 may provide each stretching mode and/or cycle mode to the user by controlling the operation of the massage device 1000 according to the massage map for each stretching mode and/or cycle mode. At this time. Massage maps may be preset from various objects and stored in the memory 1430. The object may be diverse, such as a user using the massage device, an administrator, and/or employees and doctors of various companies such as manufacturers, sellers, distributors, and developers of the massage device.

As an example, the controller 1400 may provide the iliopsoas muscle stretching mode to the user by controlling the operation of the massage device 1000 based on the massage map for the iliopsoas muscle stretching mode. Through this, the control unit 1400 can relax the iliopsoas muscle by stretching the user's iliopsoas muscle, thereby straightening the bent back and reducing excessive stress transmitted to the lumbar spine, alleviating back pain.

As another example, the controller 1400 may provide a hamstring stretching mode to the user by controlling the operation of the massage device 1000 based on a massage map for the hamstring stretching mode. Through this, the controller 1400 can relax the hamstring muscles by stretching the user's hamstrings, thereby preventing muscle shortening and injury.

As another example, the controller 1400 may provide a back stretching mode to the user by controlling the operation of the massage device 1000 based on a massage map for the back stretching mode. Through this, the control unit 1400 can relax the muscles around the lumbar spine by stretching the user's waist, thereby improving the mobility of the muscles around the lumbar spine and reducing back pain.

As another example, the controller 1400 may provide the piriformis muscle stretching mode to the user by controlling the operation of the massage device 1000 based on the massage map for the piriformis muscle stretching mode. Through this, the control unit 1400 stretches the user's buttocks (or piriformis muscle) to relax the muscles around the buttocks (or piriformis muscle), thereby reducing pain in the lower back and buttocks, numbness in the legs, sciatica, etc., and improving hip joint mobility in the lower body. It can be improved.

The control unit 1400 may provide a cycle mode to the user by controlling the operation of the massage device 1000 based on the massage map for the cycle mode. Through this, the massage device 1000 can exercise the normal leg to maintain the normal leg in a healthy state, and perform rehabilitation exercises for the abnormal leg to restore the abnormal leg to a healthy state. The massage device 1000 can prevent joint contractures by maintaining and improving the flexibility and movement of joints (pelvis, knees, ankles) by exercising the legs (or rehabilitating the legs) through repetitive joint movements. In other words, the cycle mode may be both a leg exercise mode and a leg rehabilitation mode (or knee rehabilitation mode).

FIG. 28 shows a diagram for explaining an example of the massage mode shown in FIG. 27, and FIG. 29 shows an example for explaining a reclining operation of the control unit according to an embodiment of the present disclosure.

28 and 29, the control unit 1400 may recline the massage device 1000 (S2810) and provide a stretching mode and/or an exercise mode to the user while the massage device 1000 is reclined. (S2830).

First, the control unit 1400 tilts the body massage unit 1100 toward the rear of the massage device 1000 and tilts (or rotates) each leg massage portion toward the upper side of the massage device 1000 to massage the massage device 1000. It can be reclined (S2810). The reclined massage device 1000 may be in a state in which the body massage unit 1100 is tilted toward the rear of the massage device 1000 and the leg massage unit 2000 is rotated toward the top of the massage device 1000. .

The control unit 1400 may adjust the length of each leg massage unit based on the length of each leg while tilting each leg massage unit. Since the length adjustment operation of each leg massage unit is the same as described above, detailed description will be omitted.

Afterwards, the control unit 1400 controls the operation of the massage device 1000 according to the stretching mode and/or exercise mode while the massage device 1000 is reclining, thereby providing the user with a stretching mode and/or an exercise mode. (S2830). For example, the controller 1400 may perform an operation corresponding to a stretching mode and/or an exercise mode while the massage device 1000 is in a reclining state.

Through this, the control unit 1400 reclines the massage device 1000 to secure a space for stretching the user's legs and a space for exercising the user's legs, thereby limiting the space for stretching the user's legs and exercising the legs. By eliminating space limitations, the leg stretching effect and leg exercise effect can be increased.

In addition, the control unit 1400 operates the massage unit (e.g., at least one of the body massage unit 1100, the arm massage unit 1200, and the leg massage unit 2000) while the massage device 1000 is reclining. After providing a relaxation massage that relaxes the user's body, a stretching mode and/or an exercise mode may be provided. At this time, the relaxation massage may be a massage according to a preset massage intensity and speed. For example, the relaxation massage may be provided at the average massage intensity and average massage speed among the massage intensities and speeds that the massage device 1000 can provide, or may be provided at the lowest massage intensity and lowest massage speed. Through this, the controller 1400 can relax the user's body to prevent injuries due to the stretching mode and/or exercise mode, and increase the leg stretching effect and leg exercise effect.

As described above, the control unit 1400 reclines the massage device 1000, provides a relaxation massage, and then provides a stretching mode and/or a cycle mode to the user, but is not limited to this. For example, the controller 1400 may provide a stretching mode and/or an exercise mode while performing at least one of an operation of reclining the massage device 1000 and an operation of providing a relaxation massage.

The controller 1400 may provide the piriformis muscle stretching mode to the user by controlling the operation of the massage device 1000 with an operation corresponding to the piriformis muscle stretching mode.

First, the control unit 1400 stretches the user's leg by increasing the length of any one of the first leg massage unit 2000a and the second leg massage unit 2000b through the leg length adjustment module 2500. You can do it (S3010).

The control unit 1400 may fix the user's legs by expanding the air cells of one of the leg massage parts while increasing the length of one of the leg massage parts. For example, the control unit 1400 may expand the leg air cells included in at least one leg massage unit among the upper leg massage unit and the lower leg massage unit of any one leg massage unit. Specifically, the control unit 1400 linearly expands the foot air cells (for example, at least one of the first and second sub-foot air cells, etc.) included in the lower leg massage part of any one leg massage part, and then The calf air cell (for example, at least one of the first and second sub-calf air cells, etc.) included in the upper leg massage part of the leg massage part may be post-inflated.

As described above, the control unit 1400 expands the air cells of one leg massage unit while increasing the length of one leg massage unit, but the present invention is not limited to this. For example, the controller 1400 may expand the air cells of one leg massage part and then increase the length of one leg massage part.

Through this, the control unit 1400 can sufficiently stretch the piriformis muscle of the leg by pulling (Tracting) the leg to be stretched, which is the leg corresponding to the leg massage unit of one of the user's one leg and the other leg. At this time, the control unit 1400 can accurately stretch the leg to be stretched by accurately grasping the lower part of the leg to be stretched and pulling the leg to be stretched, compared to the case where the lower part of the leg to be stretched is not fixed. Additionally, the control unit 1400 may additionally grab the upper part of the leg to be stretched and continuously pull the leg to be stretched, thereby improving the stretching effect on the leg to be stretched.

The control unit 1400 may provide a massage to the user's buttocks by moving the massage module 1110 to the user's buttocks (S3030). For example, the control unit 1400 may move the massage module 1110 to an area corresponding to the user's buttocks among the entire area of the main frame 1130. The control unit 1400 may massage the user's buttocks by protruding the massage module 1110, which has been moved to the user's buttocks, in the front direction of the massage module 1110. At this time, the forward direction of the massage module 1110 may be a direction in which the massage module 1110 approaches the user's body. In other words, the control unit 1400 may provide an acupressure massage to the user's buttocks through the massage module 1110.

Through this, the control unit 1400 can sufficiently relax the piriformis muscle by providing a massage to the stretched piriformis muscle through the massage module 1110.

FIG. 31 shows a diagram for explaining each operation of the piriformis muscle stretching mode shown in FIG. 30.

The control unit 1400 may obtain the user's shoulder position through the massage module 1110 and then recline the massage device 1000 (or recline the massage device 1000 and then use the massage module 1110 to recline the user's shoulder position). The user's shoulder position can be acquired (; Motion 1A). At this time, the control unit 1400 determines the position of the user's shoulder based on the length of each leg while reclining the massage device 1000 (or after performing a reclining operation) as described above. This allows you to adjust the length of each leg massage part.

After performing Motion 1A, the control unit 1400 selects any of the first leg massage unit 2000a and the second leg massage unit 2000b through the leg length adjustment module 2500 while the massage device 1000 is reclining. The length of one leg massage unit can be increased (Motion 1B).

First, before increasing the length of any one leg massage part, the control unit 1400 adjusts (or changes) the angle of one leg massage part through the leg angle adjustment module 1350 while the massage device 1000 is reclining. ) can be done (Motion 1B_1).

For example, the control unit 1400 operates (or drives) a leg angle adjustment module corresponding to one of the first and second leg angle adjustment modules 1350a and 1350b to massage one of the legs. The angle of the unit can be adjusted.

Specifically, the control unit 1400 tilts one of the leg massage parts in at least one of clockwise and counterclockwise directions through a leg angle adjustment module corresponding to one of the leg massage parts to adjust the angle of one of the leg massage parts. can be adjusted. At this time, the control unit 1400 may inactivate the remaining leg angle adjustment module that is different from the leg angle adjustment module corresponding to the leg massage unit of any one of the first and second leg angle adjustment modules 1350a and 1350b. Through this, the control unit 1400 can fix the position of the remaining leg massage unit that is different from any one of the first and second

leg massage units

2000a and 2000b.

As an example, the control unit 1400 maximizes the length of the leg angle adjustment module corresponding to one of the leg massage units to raise one of the leg massage units to the maximum, thereby increasing the angle of one of the leg massage units to the maximum. (Motion 1B_1a).

As another example, the control unit 1400 shortens the length of the leg angle adjustment module corresponding to one of the leg massage units to the maximum and lowers one of the leg massage units to the maximum, thereby lowering the angle of one of the leg massage units to the maximum. (Motion 1B_1b).

Through this, the control unit 1400 can flex the user's hip joint before extending the user's legs and prevent injuries to the user's body caused by extending the user's legs.

Afterwards, before increasing the length of any one leg massage part, the control unit 1400 moves the massage module 1110 to a position corresponding to the user's buttocks with the angle of one leg massage part adjusted, and massages the user's buttocks. The user's buttocks can be massaged through the module 1110 (Motion 1B_2).

For example, the controller 1400 may predict the position of the user's buttocks based on the position of the user's shoulders. The control unit 1400 moves the massage module 1110 to the user's buttocks based on the predicted position of the user's buttocks, thereby placing the massage module 1110 on the user's buttocks. As described above, the control unit 1400 moves the massage module 1110 based on the predicted position of the user's buttocks, but is not limited to this. For example, the control unit 1400 may move the massage module 1110 based on the preset position of the user's buttocks.

The control unit 1400 may provide a massage to the user's buttocks through the massage module 1110 disposed on the user's buttocks. At this time, the massage may be a variety of massages (eg, acupressure massage, kneading massage, complex massage, etc.) to reduce tension in the user's buttocks, but hereinafter, for convenience of explanation, it will be assumed to be a tapping massage. The tapping massage may be preset to various intensities and speeds that provide a soft massage feeling, such as being provided at the lowest intensity and speed among the massage intensities and speeds that the massage module 1110 can provide, or provided at the average intensity and average speed.

Through this, the control unit 1400 provides a massage that reduces tension in the buttocks muscles (e.g., piriformis muscle) before stretching and relaxing the user's buttocks muscles, thereby preventing the user's injury and side effects from stretching the piriformis muscle. You can.

As described above, the control unit 1400 moves the massage module 1110 while the angle of one leg massage unit is adjusted, but the method is not limited to this. For example, the control unit 1400 moves the massage module 1110 while adjusting the angle of one leg massage unit, or after moving the massage module 1110 (or while moving the massage module 1110). You can also adjust the angle of any one leg massage part.

Finally, after ending the Motion 1B_2 operation, the controller 1400 can increase the length of one leg massage unit through the leg length adjustment module 2500 (Motion 1B_3). At this time, the controller 1400 can stop the operation of the massage module 1110 and end the Motion 1B_2 operation. Before stopping the operation of the massage module 1110, the control unit 1400 may move the massage module 1110 as far as possible toward the rear of the massage module 1110 and then stop the massage module 1110.

For example, the control unit 1400 operates (or drives) a leg length adjustment module corresponding to one of the first and second leg

length adjustment modules

2500a and 2500b to massage one of the legs. The length of the section can be increased. At this time, the control unit 1400 may expand the air cell of any one leg massage unit as described above.

Specifically, the control unit 1400 moves one of the leg massage parts toward the lower part of one of the leg massage parts through the leg length adjustment module corresponding to one of the leg massage parts to increase the length of one of the leg massage parts. You can. At this time, the control unit 1400 may inactivate the remaining leg length adjustment module that is different from the leg length adjustment module corresponding to the leg massage unit of any one of the first and second leg

length adjustment modules

2500a and 2500b. Through this, the control unit 1400 can fix the length of the remaining leg massage unit that is different from the leg massage unit of any one of the first and second

leg massage units

2000a and 2000b.

Below, the leg length adjustment operation will be described in detail.

The control unit 1400 can increase the length of one of the leg massage parts by moving one of the leg massage parts in the lower direction of the one leg massage part based on the reference length for increasing the length of one of the leg massage parts. there is.

For example, the reference length is a reference indicating the degree of pulling the leg to be stretched and may mean a movement length (or movement distance) to move one leg massage unit in the lower direction of one leg massage unit. The reference length is a length at which the leg to be stretched can be sufficiently stretched and may be preset by various objects and stored in the memory 1430. For example, the reference length can be set in various ways, such as about 5 Cm to 10 Cm.

As described above, the standard length may be preset, but is not limited thereto. For example, the control unit 1400 may determine a custom reference length customized to the user as the reference length based on the length of the leg corresponding to the leg massage unit of one of the user's one leg and the other leg. Specifically, the memory 1430 may store a matching table in which each of the arbitrary leg lengths and each of the arbitrary reference lengths are matched to each other. The control unit 1400 may compare the user's leg length with the matching table and determine an arbitrary standard length corresponding to the leg length among arbitrary standard lengths included in the matching table as the custom reference length. The control unit 1400 may determine the customization standard length as a standard length to adjust (or increase) the length of one leg massage unit. The control unit 1400 may increase the length of any one leg massage unit based on the reference length customized for the user.

As described above, the control unit 1400 ends the Motion 1B_2 operation, which is a massage operation for massaging the user's buttocks, and then increases the length of one leg massage unit, but the method is not limited to this. For example, after terminating the Motion 1B_2 operation, the controller 1400 may increase the length of one leg massage portion while massaging at least a portion of the user's body.

Specifically, after terminating the Motion 1B_2 operation, the controller 1400 may change the position of the massage module 1110 and provide a massage to at least a portion of the user's body. At this time, the control unit 1400 may provide a massage to body parts of the user other than the user's buttocks through the massage module 1110. The control unit 1400 may increase the length of one leg massage part after providing a massage through the massage module 1110 or while providing a massage.

Additionally, the control unit 1400 may fix the user's pelvis by expanding the pelvic air cells of the body massage unit 1100 to a preset inflation level while increasing the length of one leg massage unit. At this time, the pelvic air cell may be disposed in an area corresponding to the user's pelvis, which is on both sides of the area where the user is seated, among the entire area of the massage device 1000.

As described above, the control unit 1400 expands the pelvic air cell while increasing the length of one leg massage unit, but is not limited to this. For example, the controller 1400 may expand the pelvic air cell before increasing the length of one leg massage unit.

Through this, the control unit 1400 fixes the user's legs and pelvis and extends the leg to be stretched longer, thereby stretching the leg to be stretched more accurately than when the user's pelvis is not fixed, thereby improving the stretching effect on the leg to be stretched. You can do it.

As described above, the control unit 1400 sequentially performs Motion 1B_1, 1B_2, and 1B_3, but is not limited to this. For example, the control unit 1400 can freely perform Motions 1B_1, 1B_2, and 1B_3 by controlling (or randomly) the order of operations, or can perform Motions 1B_1, 1B_2, and 1B_3 simultaneously.

When Motion 1B is performed, the control unit 1400 can provide a massage to the user's buttocks through the massage module 1110 (Motion 1C). At this time, the control unit 1400 drives the massage module 1110 when the operation of the massage module 1110 is stopped, and when the position of the massage module 1110 is not a position corresponding to the user's buttocks, the massage module ( 1110) can be moved to the user's buttocks to provide a massage to the user's buttocks.

First, the control unit 1400 can massage the user's buttocks by protruding the massage module 1110 in the front direction of the massage module 1110 based on the reference intensity for massaging the user's buttocks (Motion 1C_1). At this time, the reference intensity may refer to the degree of protrusion of the massage module 1110 as a standard representing the massage intensity of acupressure the user's buttocks. The reference intensity is a massage intensity that can sufficiently relax the user's buttocks and may be preset by various objects and stored in the memory 1430. For example, the reference intensity may be set in various ways, such as an intensity that causes the massage module 1110 to protrude about 4 to 8 cm.

As described above, the reference intensity may be preset, but is not limited thereto. For example, the control unit 1400 may determine a customized reference intensity customized to the user as the reference intensity based on various information such as at least one of the user's biometric information, massage device use history, and user preference information.

Afterwards, the control unit 1400 may additionally massage the user's buttocks by reciprocating the massage module 1110 while the massage module 1110 is protruding (Motion 1C_2). At this time, the control unit 1400 may repeatedly provide additional massage that additionally massages the user's buttocks by repeating the reciprocating motion. The reciprocating motion may mean an action of rubbing and massaging the user's buttocks through the massage module 1110.

For example, the control unit 1400 moves the massage module 1110 in the upper direction of the massage module 1110 by a preset first distance and then moves it in the lower direction of the massage module 1110 by a preset second distance. The massage module 1110 can be reciprocated. The first and second distances may be preset by various objects and stored in the memory 1430. The first and second distances may be set to be different from or equal to each other. The upward direction of the massage module 1110 is from the lower side of the massage module 1110 toward the upper side of the massage module 1110, and the downward direction of the massage module 1110 is from the upper side of the massage module 1110 to the massage module 1110. ) may be in a direction toward the lower side.

As described above, the control unit 1400 reciprocates the massage module 1110 in the upward and downward directions of the massage module 1110, but is not limited to this. For example, the control unit 1400 may reciprocate the massage module 1110 in the front and rear directions of the massage module 1110. At this time, the front direction of the massage module 1110 is from the rear of the massage module 1110 toward the front of the massage module 1110, and the rear direction of the massage module 1110 is from the front of the massage module 1110. It may be in a direction toward the rear of (1110). The front of the massage module 1110 may be a portion disposed adjacent to the user and in contact with the user's body.

Specifically, with the massage module 1110 protruding forward of the massage module 1110, the control unit 1400 further protrudes the massage module 1110 in the front direction of the massage module 1110 by a first distance and then The massage module 1110 can be reciprocated by retreating a distance of 2 toward the rear of the massage module 1110.

When additionally massaging the user's buttocks through the reciprocating movement of the massage module 1110 described above, the control unit 1400 reduces the length of one leg massage unit by a preset length and expands the pelvic air cells of the body massage unit 1100. By inflating it to the maximum, the user's pelvis can be strongly fixed. For example, the controller 1400 may expand the pelvic air cells to the maximum while reciprocating the massage module 1110 or before reciprocating the massage module 1110.

Through this, the control unit 1400 can accurately provide additional massage to the user's buttocks by strongly fixing the user's pelvis while reciprocating the massage module 1110.

As described above, the control unit 1400 performs piriformis muscle stretching movements (

Motions

1A, 1B, and 1C) through one of the leg massage units, but is not limited to this. For example, the control unit 1400 may perform piriformis muscle stretching movements (

Motions

1A, 1B, and 1C) through one leg massage unit, and then additionally perform piriformis muscle stretching movements for the remaining leg massage units. At this time, the piriformis muscle stretching operation for the remaining leg massage unit may be the same as

Motion

1A, 1B, and 1C.

Additionally, the control unit 1400 may sequentially and repeatedly perform the piriformis muscle stretching operation for each leg massage unit described above.

Through this, the control unit 1400 can sufficiently stretch and relax the user's piriformis muscle by stretching both legs and both buttocks of the user in a balanced manner and overall relaxing the user's legs and buttocks by repeatedly stretching them.

Additionally, the controller 1400 may provide a thermal massage by increasing the temperature of the massage module 1110 while providing a massage to the user's buttocks through the massage module 1110 while performing a piriformis muscle stretching operation.

Through this, the control unit 1400 provides a thermal sensation to the user's buttocks and stretches and relaxes the user's buttocks, so that the user's buttocks stretch and relax more than when the thermal sensation is not provided, and injuries resulting from stretching and relaxation are prevented. It can be prevented.

The body massage unit 1000 may include body air cells 1600 that massage (or pressurize) the user's body.

FIG. 33 shows a flowchart for explaining the iliopsoas muscle stretching mode shown in FIG. 27, and FIG. 34 shows a diagram for explaining each operation shown in FIG. 33.

The control unit 1400 may provide the user with an iliopsoas muscle stretching mode that stretches the iliopsoas muscle of the user's leg by controlling the operation of the massage device 1000 with an operation corresponding to the iliopsoas muscle stretching mode. At this time, the iliopsoas muscle stretching mode may include a leg stretching action that stretches the user's leg (or the iliopsoas muscle of the leg).

For example, the controller 1400 may recline the massage device 1000 using Motion 2A before performing a leg stretching motion (S3310).

Specifically, the control unit 1400 tilts (or tilts) the body massage unit 1100 toward the rear of the body massage unit 1100 based on the preset body angle, and then controls the leg massage unit 1100 based on the preset leg angle. The angle of the leg massage unit 2000 can be adjusted by tilting (2000) toward the upper side of the massage device 1000.

The body angle and leg angle may be preset from various objects and stored in the memory 1430. The body angle is one of the minimum body angle and the maximum body angle between the ground and the body massage unit 1100, and may be greater than the minimum body angle and smaller than the maximum body angle. The minimum body angle may be the angle at which the body massage unit 1100 is maximally tilted (maximally inclined) in the front direction of the body massage unit 1100. The maximum body angle may be the maximum tilt angle of the body massage unit 1100 toward the rear of the body massage unit 1100. The leg angle is one of the minimum leg angle and the maximum leg angle between the body massage unit 1100 and each leg massage unit, and may be greater than the minimum leg angle and smaller than the maximum leg angle. The minimum leg angle may be the maximum tilt angle of each leg massage unit in the downward direction of the massage device 1000. The maximum leg angle may be the maximum tilt angle of each leg massage unit in the upper direction of the massage device 1000.

The controller 1400 may perform a preliminary operation including at least one of providing a relaxation massage and measuring a leg length while the massage device 1000 is reclining.

For example, the controller 1400 may provide (or provide) a relaxation massage to relax the user's body and measure the user's leg length.

Since the operation of providing a relaxation massage and the operation of measuring leg length are the same as described above, detailed descriptions will be omitted. However, the control unit 1400 may move the massage module 1110 to a position corresponding to the user's buttocks while providing a relaxation massage. Since the content described in Motion 1B_2 can be applied to the massage module movement operation, detailed explanation will be omitted.

The control unit 1400 may perform a leg stretching operation while the massage device 1000 is reclined through the leg length adjustment module 2500 and the leg angle adjustment module 1350 (S3330).

The leg stretching action may include a first leg stretching action and/or a second leg stretching action. The first leg stretching operation may stretch one leg of the user to stretch the iliopsoas muscle of one leg. The second leg stretching operation may stretch the user's other leg to stretch the iliopsoas muscle of the other leg.

For example, the control unit 1400 may sequentially and repeatedly perform the first and second leg stretching movements based on a preset number of repetitions. At this time, the number of repetitions may be preset from various objects and stored in the memory 1430. Hereinafter, for convenience of explanation, it will be assumed that the first and second leg stretching movements are not repeatedly performed.

First, the control unit 1400 may perform a first leg stretching motion such as Motion 2B (S3331).

For example, the control unit 1400 may increase the length of the first leg massage unit 2000a while adjusting or maintaining the length of the second leg massage unit 2000b, as in Motion 2B-1. At this time, the length of the first leg massage unit 2000a may mean the length from one end to the other end of the first leg massage unit 2000a. The length of the second leg massage unit 2000b may refer to the length from one end to the other end of the second leg massage unit 2000b.

Specifically, the control unit 1400 may determine an adjustment length for adjusting the length of the first leg massage unit 2000a based on the length of one leg of the user. The control unit 1400 may adjust the length of the first leg massage unit 2000a based on the adjusted length. The length adjustment operation of the first leg massage unit 2000a will be described in detail below.

Hereinafter, for convenience of explanation, it will be assumed that the length of the first leg massage unit 2000a is adjusted while the length of the second leg massage unit 2000b is adjusted during the first leg stretching operation.

The control unit 1400 can adjust the angle of the first leg massage unit 2000a while maintaining the angle of the second leg massage unit 2000b, as in Motion 2B-2. At this time, the angle of the first leg massage unit 2000a may mean the angle between the first leg massage unit 2000a and the body massage unit 1100 (or the seat portion of the body massage unit). The angle of the second leg massage unit 2000b may refer to the angle between the second leg massage unit 2000b and the body massage unit 1100.

For example, the control unit 1400 may determine an adjustment angle to adjust the angle of the first leg massage unit 2000a based on the length of one leg of the user. The control unit 1400 may adjust the angle of the first leg massage unit 2000a based on the adjustment angle. The angle adjustment operation of the first leg massage unit 2000a will be described in detail below.

The control unit 1400 may restore the position of the leg massage unit 2000 after performing the first leg stretching operation. The restored angle and length of the leg massage unit 2000 may be the angle and length of the leg massage unit 2000 before the first leg stretching operation is performed.

Afterwards, the controller 1400 may perform a second leg stretching motion such as Motion 2C (S3333).

For example, the control unit 1400 may increase the length of the second leg massage unit 2000b while adjusting or maintaining the length of the first leg massage unit 2000a, as in Motion 2C-1.

Specifically, the control unit 1400 may determine an adjustment length for adjusting the length of the second leg massage unit 2000b based on the length of the user's other leg. The control unit 1400 may adjust the length of the second leg massage unit 2000b based on the adjusted length. The length adjustment operation of the second leg massage unit 2000b may be an operation of adjusting the length of the first leg massage unit 2000a included in the first leg stretching operation described later.

Hereinafter, for convenience of explanation, it will be assumed that the length of the second leg massage unit 2000b is adjusted while the length of the first leg massage unit 2000a is adjusted during the second leg stretching operation.

The control unit 1400 can adjust the angle of the second leg massage unit 2000b while maintaining the angle of the first leg massage unit 2000a, as in Motion 2C-2.

For example, the control unit 1400 may determine an adjustment angle to adjust the angle of the second leg massage unit 2000b based on the length of the user's other leg. The control unit 1400 may adjust the angle of the second leg massage unit 2000b based on the adjustment angle. The angle adjustment operation of the second leg massage unit 2000b may be an angle adjustment operation of the first leg massage unit 2000a included in the first leg stretching operation described later.

The control unit 1400 may restore the position of the leg massage unit 2000 after performing the second leg stretching operation.

After performing the leg stretching motion, the control unit 1400 performs final stretching of the user's legs and buttocks through the leg length adjustment module 2500, leg angle adjustment module 1350, and massage module 1110 like Motion 2D. A massage providing operation may be performed (S3350).

For example, the control unit 1400 may reduce the length of each leg massage unit while tilting each leg massage unit toward the upper side of the massage device 1000 while the position of the leg massage unit 2000 is restored. As an example, the control unit 1400 may adjust the angle and length of each leg massage unit based on the adjustment length and adjustment angle according to the length of each leg. As another example, the controller 1400 may adjust the angle of each leg massage unit to the maximum leg angle and reduce the length of each leg massage unit to the minimum length.

The control unit 1400 may provide a massage to the user's buttocks through the massage module 1110 while the angle and length of each leg massage unit are adjusted. At this time, the massage provided to the buttocks may be a piriformis muscle stretching mode buttock massage, such as at least one of acupressure massage, kneading massage, tapping massage, and combined massage.

The control unit 1400 may end the iliopsoas muscle stretching mode after providing the massage massage.

The length adjustment operation of each leg massage unit included in the above-described first and second leg stretching operations may be performed simultaneously, at a time difference, or sequentially. Hereinafter, for convenience of explanation, it will be assumed that the length adjustment operation of each leg massage unit is performed simultaneously.

In the following, since the first leg stretching motion can be applied to the second leg stretching motion, only the first leg stretching motion will be described for convenience of explanation. For example, the operation of the first leg massage unit 2000a included in the first leg stretching operation may be applied to the operation of the second leg massage unit 2000b included in the second leg stretching operation. The operation of the second leg massage unit 2000b included in the first leg stretching operation may be applied to the operation of the first leg massage unit 2000a included in the second leg stretching operation.

The control unit 1400 may increase the length of the first leg massage unit 2000a while decreasing the length of the second leg massage unit 2000b through the leg length adjustment module 2500 (S3331a).

For example, the control unit 1400 may tilt the leg massage unit 2000 toward the upper side of the massage device 1000 as much as possible based on the maximum leg angle while the massage device 1000 is reclining.

The control unit 1400 may increase the length of the first leg massage unit 2000b while decreasing the length of the second leg massage unit 2000a by a preset length while the leg massage unit 2000 is tilted as much as possible.

When reducing the length of the second leg massage unit 2000b, the control unit 1400 operates the second leg massage unit 2000b in a state in which the second leg air cell 1730 is contracted. The length of the second leg massage unit 2000b can be reduced to the shortest minimum length by moving it as much as possible in the upper direction, but it is not limited to this. For example, the control unit 1400 may reduce the length of the second leg massage unit 2000b based on the length of the user's other leg, similar to the method of adjusting the length of the first leg massage unit 2000a, which will be described later. You can.

When increasing the length of the first leg massage unit 2000a, the control unit 1400 expands (or inflates) the first leg air cell 1710 and uses the first leg massage unit (2000a) based on the length of one leg of the user. 2000a) can be increased in length. The method of inflating the first leg air cell 1710 includes inflating the leg air cells (e.g., first and second sub-calf air cells, first and second sub-foot air cells, etc.) in operation S3010 of the piriformis muscle stretching mode. It can be applied.

For example, the control unit 1400 may determine an adjustment length to increase the length of the first leg massage unit 2000a based on the length of one leg of the user. The control unit 1400 may increase the length of the first leg massage unit 2000a by moving the first leg massage unit 2000a in a downward direction of the first leg massage unit 2000a based on the adjusted length. At this time, the control unit 1400 may move the first leg massage unit 2000a by the adjustment length or move it to a position corresponding to the first adjustment length.

The method for determining the above-mentioned adjustment length may be as follows. For example, the memory 1430 may store a leg length table including a plurality of leg lengths and an adjustment length matched to each leg length. The leg length table may be preset by various objects and stored in the memory 1430. The control unit 1400 may extract an adjustment length that matches one leg length among a plurality of leg lengths in the leg length table based on the length of one leg of the user. At this time, the length of one leg may be the same or similar to the length of the user's one leg. The control unit 1400 may determine the extracted adjustment length as an adjustment length for adjusting the length of the first leg massage unit 2000a.

That is, the control unit 1400 expands only the first leg air cell 1710 to fix (or fix) one leg of the user to the first leg massage unit 2000a and adjusts the length of the first leg massage unit 2000a. By doing so, one leg of the user can be stretched.

In addition, when increasing the length of the first leg massage unit 2000a, the control unit 1400 operates the first foot massage unit 2610 while the second foot massage unit 2630 is stopped to The length of the first leg massage part 2000a may be increased while massaging (or massaging). At this time, the driving operation of the first foot massage unit 2610 may be linked to at least one of the expansion operation of the first leg air cell 1710 and the length increasing operation of the first leg massage unit 2000a. The driving operation of the first foot massage unit 2610 may be terminated when the length increasing operation of the first leg massage unit 2000a is completed.

In other words, the control unit 1400 controls the driving operation of the first foot massage unit 2610 while the second foot massage unit 2630 is stopped and the second leg air cell 1730 is contracted, and the first leg air cell ( At least one of the expansion operation of 1710 and the length increase operation of the first leg massage unit 2000a may be linked to stretch one leg of the user.

The control unit 1400 can adjust the angle of the first leg massage unit 2000a while maintaining the angle of the second leg massage unit 2000b through the leg angle adjustment module 1350 (S3331b).

For example, the control unit 1400 operates the first leg massage unit 2000a in a state in which the length of the first leg massage unit 2000a is increased and the first leg air cell 1710 is inflated using the massage device 1000. The angle of the first leg massage unit 2000a can be adjusted by tilting in the downward direction.

When adjusting the angle of the first leg massage unit 2000a, the control unit 1400 may adjust the angle of the first leg massage unit 2000a based on the length of one leg of the user.

For example, the control unit 1400 may determine an adjustment angle to adjust the angle of the first leg massage unit 2000a based on the length of one leg of the user. The control unit 1400 may adjust the angle of the first leg massage unit 2000a by tilting the first leg massage unit 2000a toward the lower side of the massage device 1000 based on the adjustment angle. At this time, the control unit 1400 may tilt the first leg massage unit 2000a by the adjustment angle or tilt it to a position corresponding to the adjustment angle.

The method for determining the adjustment angle described above may be similar to the method for determining the adjustment length. For example, the memory 1430 may store a leg angle table including a plurality of leg lengths and an adjustment angle matched to each leg length. The leg angle table may be preset by various objects and stored in the memory 1430. The control unit 1400 may extract an adjustment angle that matches one leg length among a plurality of leg lengths previously stored in the memory 1430 based on the length of one leg of the user. At this time, the length of one leg may be the same as or similar to the length of the user's one leg. The control unit 1400 may determine the extracted adjustment angle as an adjustment angle to adjust the angle of the first leg massage unit 2000a.

That is, the control unit 1400 adjusts the angle of the first leg massage unit 2000a in a state in which the length of the first leg massage unit 2000a is increased and the first leg air cell 1710 is inflated to one side of the user. You can stretch your legs.

As described above, the control unit 1400 adjusts the angle of the first leg massage unit 2000a while maintaining the angle of the second leg massage unit 2000b, but the present invention is not limited to this.

For example, the control unit 1400 links at least one of the angle adjustment operation of the first leg massage unit 2000a, the reclining operation of the body massage unit 1100, the expansion operation of the body air cell 1600, and the buttock massage providing operation. It can be done by doing this.

In the case of the body massage unit 1100 reclining operation, the control unit 1400 reclines the body massage unit 1100 while maintaining the angle between the body massage unit 1100 and the second leg massage unit 2000b. The angle of the massage unit 2000b can be adjusted. For example, the control unit 1400 may tilt the body massage unit 1100 toward the rear of the body massage unit 1100 as much as possible based on the maximum body angle.

In the case of the body air cell 1600 expansion operation, the control unit 1400 may expand the body air cell 1600 to move (or move) the user's body and then adjust the angle of the first leg massage unit 2000a. At this time, the control unit 1400 may expand the body air cell 1600 after increasing (or while increasing) the length of the second leg massage unit 2000b.

As an example, the control unit 1400 expands at least one of the

thigh air cells

1617 and 1637 and the perineal air cell 1650 to move the user's body toward the upper side of the massage device 1000 (or while moving it). , the angle of the first leg massage unit 2000a can be adjusted. At least one air cell among the

thigh air cells

1617 and 1637 and the perineum air cell 1650 expands while the length of the first leg massage part 2000a is increasing or the length of the first leg massage part 2000a is increased. It can be.

As another example, the control unit 1400 expands at least one of the

back air cells

1613 and 1633 and the

pelvic air cells

1615 and 1635 to move the user's body to one of the two sides of the massage device 1000. After doing so (or while moving it), the angle of the first leg massage unit 2000a can be adjusted. At least one of the

back air cells

1613 and 1633 and the

pelvic air cells

1615 and 1635 is in a state in which the length of the first leg massage unit 2000a is increased or the length of the first leg massage unit 2000a is increased. can be expanded in

For example, the at least one air cell may include at least one of the second back air cell 1633 and the second pelvic air cell 1635 corresponding to the second leg massage unit 2000b. In other words, the control unit 1400 expands at least one air cell of the second back air cell 1633 and the second pelvic air cell 1635 to massage the user's body with the first leg massage unit ( 2000a) can be moved to the corresponding side.

As another example, the control unit 1400 inflates (or inflates) at least one of the back air cells (1613, 1633) and the pelvic air cells (1615, 1635), the thigh air cells (1617, 1637), and the perineum air cell (1650). ), the angle of the second leg massage unit 2000b can be adjusted after moving (or moving) the user's body by expanding at least one air cell.

In the case of providing a buttock massage, the control unit 1400 uses the massage module 1110 before or after adjusting the angle of the first leg massage unit 2000a, or while adjusting the angle of the first leg massage unit 2000a. A buttock massage may be provided to the user's buttocks.

Specifically, the control unit 1400 may provide a buttocks massage to the user by protruding the massage module 1110 in the front direction of the massage module 1110 and pressing the user's buttocks. At this time, the control unit 1400 may provide a buttock massage to the user by protruding the massage module 1110 when the angle adjustment of the first leg massage unit 2000a is completed, but the present invention is not limited to this. The buttocks massage may include at least one of acupressure massage, kneading massage, tapping massage, and combination massage. A complex massage may be a massage that combines two or more of acupressure massage, kneading massage, and tapping massage. At least some of the buttock massage movements included in the above-described piriformis muscle stretching operation may be applied to the above-described buttock massage providing operation.

As described above, the control unit 1400 performs at least one of the angle adjustment operation of the first leg massage unit 2000a, the reclining operation of the body massage unit 1100, the expansion operation of the body air cell 1600, and the buttock massage providing operation. It is performed in conjunction, but is not limited to this.

For example, the control unit 1400 may perform an angle adjustment operation of the second leg massage unit 2000b in conjunction with an angle adjustment operation of the first leg massage unit.

Specifically, the control unit 1400 adjusts the angle of the second leg massage unit 2000b by tilting the second leg massage unit 2000b in at least one of the upper and lower directions of the massage device 1000, thereby adjusting the angle of the second leg massage unit 2000b. 1 The angle of the leg massage unit 2000a can be adjusted. Preferably, the second leg air cell 1710 of the second leg massage unit 2000b is in a contracted state, so the second leg massage unit 2000b may be tilted toward the upper side of the massage device 1000.

Through this, the control unit 1400 quickly and accurately extends and relaxes the user's one leg (or the iliopsoas muscle of one leg), which is the leg to be stretched, and uses unnecessary power to expand the second leg air cell 1730. It can prevent waste and reduce the occurrence of injuries to the user's body.

In addition, the control unit 1400 extends and relaxes the user's leg more than in the case where one leg of the user is not fixed to the first leg massage unit 2000a and in the case where the body air cell 1400 is not inflated, thereby providing a stretching effect. can be improved.

Additionally, the control unit 1400 can massage the foot of one of the user's legs to make the user recognize that the user's one leg is the leg to be stretched, thus preventing injury and promoting (or inducing) the user's mental and physical stability.

In addition, the control unit 1400 operates on one leg (or the iliopsoas muscle of one leg) of the user more than when at least one of the body massage unit 1100 reclining operation, the body air cell 1600 expansion operation, and the buttock massage providing operation is not performed. Extension and relaxation can be achieved more quickly and accurately.

In addition, the control unit 1400 extends and relaxes the user's one leg (or the iliopsoas muscle of one leg) more quickly and accurately than when the first and second leg massage unit angle adjustment operations are not performed in conjunction with each other. You can do it.

In the above, the technical idea of the present invention has been described along with the accompanying drawings, but this is an exemplary description of a preferred embodiment of the present invention and does not limit the present invention. In addition, it is clear that anyone skilled in the art of the present invention can make various modifications and imitations without departing from the scope of the technical idea of the present invention.

Additionally, the configuration and functions of the massage device of this specification can be expanded and applied to various (wearable) healthcare devices that can provide healthcare functions (eg, massage/massage function, bio-signal measurement function, etc.). Therefore, of course, the 'massage device' in this specification can be replaced with a '(wearable) healthcare device'.
