Description

[0001] This application is a divisional application of a Chinese patent application with the application number 202390000072.9, the date of entry into the Chinese national phase being September 19, 2023, and the utility model name being "Massage device providing a massage mode for stretching a user's legs". Technical Field

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

[0003] Massage refers to a medical auxiliary therapy that adjusts the physical changes of a massage object by applying various mechanical stimuli to a part of the massage object's body, such as kneading, pressing, stretching, patting, or moving a part of the body, which helps with the blood cycle and relieves the fatigue of the massage object.

[0004] Due to economic circumstances and time reasons, the demand for massage devices providing manual massage functions has increased. As the demand for relieving stiff muscles and eliminating fatigue or stress through massage has increased, various massage devices with good time and cost benefits have been introduced.

[0005] Recently, people's attention to health has been increasing, and massage devices have changed from simply providing massage functions to electronic devices providing various additional functions and / or medical functions. Therefore, research on methods for effectively controlling massage devices continues.

[0006] In particular, since the parts of the body that each user wants to be massaged and the desired stimuli may vary, research activities on devices and methods for providing optimized forms of massage to each user are increasing.

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

[0008] On the other hand, in the case of an independently driven leg massage part, since the leg massage part is independently driven, there is a problem that a part of the user's body may be caught between the leg massage parts. Such a problem may lead to a safety accident.

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

[0083] The leg massage unit 1300 includes an accommodation space for accommodating the legs of the user, and can provide leg massage to the user by massaging at least a part of the legs of the user. For example, the leg massage unit 1300 may include a calf massage unit for massaging the calf of the user and / or a foot massage unit for massaging the foot of the user.

[0084] The leg massage unit 1300 can adjust its length according to the user's physical characteristics. For example, when a tall user uses the massage device 1000, since the user has a long calf length, the length of the leg massage unit 1300 needs to be increased. In addition, when a short user uses the massage device 1000, since the user has a short calf length, the leg massage unit 1300 needs to be shortened. Therefore, the leg massage unit 1300 can provide leg massage that matches the user's height. According to an embodiment of the present invention, the user can control the massage device 1000 by using the massage device control device CD. The massage device control device CD can be connected to the massage device 1000 through wired communication and / or wireless communication.

[0087] According to an embodiment of the present invention, the main frame 1130 may include an upper frame 1131 provided with a massage module 1110 and a base frame 1132 for supporting the upper frame 1131.

[0088] At least a part of the upper frame 1131 may be provided with a rack 1131a. The rack 1131a is a member for guiding the up and down movement of the massage module 1110 and may include a plurality of valleys and a plurality of ridges.

[0089] According to an embodiment of the present invention, the racks 1131a may be provided facing each other on both sides of the upper frame 1131, and the massage module 1110 can move along the racks 1131a.

[0090] In Figure 2 the rack 1131a is formed in the up and down direction, but is not limited thereto. The rack 1131a may include a rack in the front and rear direction and a rack in the up and down direction. In the present invention, the front and rear direction may refer to the direction from the massage module 1110 towards the user or from the user towards the massage module 1110, and may refer to the X-axis direction with Figure 2 as a reference.

[0091] The massage module 1110 may include a gear meshing with the rack 1131a. More specifically, the massage module 1110 may include gears meshing with the rack in the front - rear direction and the rack in the up - down direction respectively. The gears are rotated by an actuator provided in the massage module 1110, so that the massage module 1110 can move forward, backward, upward or downward.

[0092] As the massage module 1110 moves forward, the massage intensity can increase. Additionally, as the body massage module 1110 moves backward, the massage intensity can decrease.

[0093] The rack 1131a can be made of a metal material or a plastic material. For example, the rack 1131a can be made of iron, steel, alloy, reinforced plastic, melamine resin, phenolic resin, etc., but is not limited thereto.

[0094] The upper frame 1131 can be implemented in various shapes. For example, according to the shape, the upper frame 1131 can be divided into an S - frame, an L - frame, an S&L - frame, a double S&L - frame, but is not limited thereto.

[0095] The S - frame refers to a frame in which at least a part of the upper frame 1131 has a shape curved like an "S". The L - frame refers to a frame in which at least a part of the upper frame 1131 includes a shape curved like an "L"; the S&L - frame refers to a frame including both a shape curved like an "S" and a shape curved like an "L"; the double S&L - frame refers to a frame including a shape curved like an "L" and two parts curved like an "S".

[0096] The base frame 1132 refers to the part that supports the upper frame 1131 and contacts the ground. The base frame 1132 may include an upper base frame 1132a and a lower base frame 1132b.

[0097] The upper base frame 1132a can support the upper frame 1131, and the lower base frame 1132b can contact the ground. Additionally, the upper base frame 1132a can be arranged in a manner that connects with the lower base frame 1132b.

[0098] According to an embodiment of the present utility model, the upper base frame 1132a can move along the lower base frame 1132b. For example, the upper base frame 1132a can slide forward or backward along the lower base frame 1132b. In this case, the upper frame 1131 is connected to the upper base frame 1132a, so that it can move as the upper base frame 1132a moves.

[0099] For example, when the upper base frame 1132a moves forward, the upper frame 1131 can also move forward together. When the upper base frame 1132a moves backward, the upper frame 1131 can also move backward together. This allows the sliding movement of the body massage unit 1100.

[0100] To allow the movement of the upper base frame 1132a, moving wheels can be provided at the lower part of the upper base frame 1132a. Additionally, a guiding member capable of guiding the moving wheels can be provided at the upper part of the lower base frame 1132b. The moving wheels provided on the upper base frame 1132a move along the guiding member provided on the lower base frame 1132b, thereby allowing the upper base frame 1132a to move forward or backward.

[0101] According to another embodiment of the present utility model, the massage device 1000 may not provide a sliding function. In this case, the base frame 1132 may not be separated into an upper frame and a lower frame.

[0182] The first central rotating member 1532a and the second central rotating member 1532b can be rotatably coupled to the first central fixing member 1531a and the second central fixing member 1531b, respectively.

[0183] The first central fixing member 1531a and the first central rotating member 1532a can rotatably fix the first central bushing 1311. The second central fixing member 1531b and the second central rotating member 1532b can rotatably fix the second central bushing 1321.

[0184] Figure 13a It is a view showing the central support bracket according to another embodiment of the present utility model, Figure 13b It is a view showing the central support bracket according to still another embodiment of the present utility model.

[0185] Refer toFigure 13a The first central rotating member 1532a and the second central rotating member 1532b can be connected by a central rotating member cover 1532c. For example, one side of the central rotating member cover 1532c can be connected to the inner side of the first central rotating member 1532a, and the other side can be connected to the inner side of the second central rotating member 1532b. The central rotating member cover 1532c can be welded to the first central rotating member 1532a and the second central rotating member 1532b, or can be connected by separate fastening members. However, the first central rotating member 1532a, the second central rotating member 1532b, and the central rotating member cover 1532c can also be integrally formed. In other words, the first central rotating member 1532a, the second central rotating member 1532b, and the central rotating member cover 1532c can be integrally formed by bending and cutting a single member multiple times.

[0186] Refer to Figure 13b The central rotating member cover 1532c can be connected to the outer sides of the first central rotating member 1532a and the second central rotating member 1532b. The central rotating member cover 1532c can be welded to the first central rotating member 1532a and the second central rotating member 1532b, or can be connected by separate fastening members. In this case, the central rotating member cover 1532c can be configured to entirely cover the upper portions of the first central rotating member 1532a and the second central rotating member 1532b.

[0187] Moreover, the central rotating member cover 1532c can be connected to the first central rotating member 1532a and the second central rotating member 1532b through mechanical structures such as a sliding fit or a hook fit. As long as the central rotating member cover 1532c corresponds to a structure configured to cover at least a part of the upper portions of the first central rotating member 1532a and the second central rotating member 1532b, the structure for connecting the central rotating member cover 1532c can be replaced by various methods common in the technical field to which the present utility model pertains.

[0188] The central support bracket 1530 can correspond to a component of the safety sensor module 1500 described later. The specific structure of the central support bracket 1530 will be described in detail later.

[0189] The side support brackets 1550 can be provided on both sides of the leg connection frame 1131b. The side support brackets 1550 can include a first side support bracket 1550a provided at the right end of the leg connection frame 1131b and a second side support bracket 1550b provided at the left end. The first side support bracket 1550a and the second side support bracket 1550b can be provided in corresponding shapes.

[0190] The first side support bracket 1550a can rotatably fix the first side bushing 1312. The second side support bracket 1550b can rotatably fix the second side bushing 1322. To enable smooth rotation between the side support brackets 1550 and the side bushings 1312, 1322, bearings can be provided.

[0191] For example, the side support bracket 1550 can include a side fixing member 1551 and a side rotating member 1552.

[0192] The side fixing member 1551 can be welded to the leg connection frame 1131b or can be joined by a separate fastening member. The side fixing member 1551 can be rotatably joined to one side of the side rotating member 1552. When the side rotating member 1552 rotates such that its end contacts the side fixing member 1551, they can be connected by a fastening member.

[0193] Figure 14 Parts (a) and (b) are diagrams showing the process of fastening the center bushing to the center support bracket. Figure 14 Parts (c) and (d) are diagrams showing the process of fastening the side bushing to the side support bracket.

[0194] Referring to Figure 14 Parts (a) and (b), the process of fastening the first center bushing 1311 to the center support bracket 1530 will be described.

[0195] The first center fixing member 1531a can be joined to the leg connection frame 1131b. For example, the first center fixing member 1531a can be welded to the leg connection frame 1131b in a state where the leg connection frame 1131b is inserted into the leg connection frame insertion slot 1531d-1 formed on one side of the first center fixing member 1531a, or can be joined by a separate fastening member.

[0196] When the first center fixing member 1531a is joined to the leg connection frame 1131b, the first center rotating member 1532a can rotate upward. For example, the first center rotating member 1532a can be rotatably hinged to the first center fixing member 1531a via a center rotation shaft 1532a-1 and can rotate upward based on the center rotation shaft 1532a-1. Here, the center rotation shaft 1532a-1 can refer to a separate rotation shaft that rotatably connects the first center fixing member 1531a and the first center rotating member 1532a. However, the center rotation shaft 1532a-1 can also be integrated with either the first center fixing member 1531a or the first center rotating member 1532a.

[0197] The first central bushing 1311 can be disposed in the central bushing receiving groove 1531d-5 of the first central fixing member 1531a.

[0198] When the first central bushing 1311 is disposed, the first central rotating member 1532a can rotate downward. At this time, at least a part of the upper outer peripheral surface of the first central bushing 1311 can be received in the central bushing fixing groove 1532d of the first central rotating member 1532a. The central bushing receiving groove 1531d-5 and the central bushing fixing groove 1532d can rotatably support the first central bushing 1311.

[0199] When the first central rotating member 1532a rotates downward and the end contacts the fixing piece 1531d-4 of the first central fixing member, the first central rotating member 1532a can be connected to the fixing piece 1531d-4 by a fastening member.

[0200] The process of fastening the second central bushing 1321 to the central support bracket 1530 is the same as the process of fastening the first central bushing 1311 to the central support bracket 1530 described above.

[0201] Refer to Figure 14 Parts (b) and (c) to describe the process of fastening the first side bushing 1312 to the first side support bracket 1550a.

[0202] The side fixing member 1551 can be combined with the leg connection frame 1131b. For example, the side fixing member 1551 can be welded to the leg connection frame 1131b or can be combined by a separate fastening member.

[0203] When the side fixing member 1551 is combined with the leg connection frame 1131b, the side rotating member 1552 can rotate upward. For example, the side rotating member 1552 can be rotatably hinge-combined to the side fixing member 1551 through the side rotation shaft 1552b and can rotate upward based on the side rotation shaft 1552b. Here, the side rotation shaft 1552b can refer to a separate rotation shaft that rotatably connects the side fixing member 1551 and the side rotating member 1552. However, the side rotation shaft 1552b can also be provided integrally with either the side fixing member 1551 or the side rotating member 1552.

[0204] The first side bushing 1312 can be disposed in the side bushing receiving groove 1551a of the side fixing member 1551.

[0205] When the first side bushing 1312 is placed, the side rotating member 1552 can rotate downward. At this time, at least a part of the upper outer peripheral surface of the first side bushing 1312 can be received in the side bushing fixing groove 1552a of the side rotating member 1552. The side bushing receiving groove 1551a and the side bushing fixing groove 1552a can rotatably support the first side bushing 1312.

[0206] When the side rotating member 1552 rotates downward and its end contacts the side fixing member 1551, the side rotating member 1552 can be connected to the side fixing member 1551 by a fastening member.

[0207] The process of fastening the second side bushing 1322 to the second side support bracket 1550b is the same as the process of fastening the first side bushing 1312 to the first side support bracket 1550a described above.

[0208] As described above, since the center bushing and the side bushings can be fixed by placing and fastening them to the center support bracket 1530 and the side support brackets 1550, the leg massage unit 1300 can be easily connected to the body massage unit 1100.

[0209] Figure 15 Yes Figure 7 is an enlarged view of part D of Figure 16 is a view showing a disassembled state of a safety sensor module according to an embodiment of the present invention, Figure 17 is a view showing another embodiment of a safety sensor module according to an embodiment of the present invention.

[0210] Referring to Figure 15 and Figure 16 , a massage device 1000 according to an embodiment of the present invention may include a safety sensor module 1500.

[0211] The safety sensor module 1500 can be provided on the leg connection frame 1131b. For example, the safety sensor module 1500 can be provided on a part of the leg connection frame 1131b corresponding to the space between the first leg massage unit 1310 and the second leg massage unit 1330.

[0212] When an external force is applied, the safety sensor module 1500 may control the driving of at least one of the first leg massage part 1310 and the second leg massage part 1330. For example, when an external force is applied, the safety sensor module 1500 may stop the rotation operation of at least one of the first leg massage part 1310 and the second leg massage part 1330. In addition, when an external force is applied, the safety sensor module 1500 may rotate the first leg massage part 1310 and the second leg massage part 1330 by a specified angle in a direction opposite to the direction in which at least one of the first leg massage part 1310 and the second leg massage part 1330 rotates.

[0213] The safety sensor module 1500 may include an alarm unit (not shown), which sends a warning signal to the user when an external force is applied. The alarm unit may include, for example, at least one of a light, an audio, and a vibration element. The light can send a warning signal by irradiating light to the user. The audio may correspond to the audio output module 1120 or may refer to a separate audio device. The audio may send a warning signal to the user through an alarm sound. The vibration element may be provided as a vibration panel, a vibration actuator, etc. The vibration element may be provided in at least one of the body massage unit 1100, the arm massage unit 1200, and the leg massage unit 1300 to apply vibration to the user, thereby sending a warning signal. At this time, the light and / or the vibration element may be provided in the leg massage unit 1300. For example, the light can be provided at various positions of the appearance (or exterior) of the leg massage unit 1300. The vibration element may be provided in an area adjacent to the user's body (e.g., an area corresponding to the sole of the foot and an area corresponding to the calf, etc.) in the entire area of the leg massage unit 1300.

[0214] Therefore, the safety sensor module 1500 can prevent a safety accident that may occur due to the user's body being caught between the leg massaging parts 1300. In addition, the safety sensor module 1500 can prevent device damage / malfunction that may occur due to an object flowing between the leg massaging parts 1300.

[0215] The safety sensor module 1500 may include a sensor bracket 1510 , a sensor 1520 , a center support bracket 1530 , and a pressure plate 1540 .

[0216] A sensor bracket 1510 may be provided to support the sensor 1520. The sensor bracket 1510 may be coupled to the leg connection frame 1131b. For example, the sensor bracket 1510 may be welded to the leg connection frame 1131b or may be coupled by a separate fastening member. The method of coupling the sensor bracket 1510 to the leg connection frame 1131b may be replaced by various methods commonly used in the technical field to which the present utility model belongs.

[0217] The sensor bracket 1510 may include a protruding portion 1511 and a bending portion 1512. One side of the protruding portion 1511 may be coupled to the leg connection frame 1131b, and the other side may protrude forward. The bending portion 1512 may be bent downward at the other protruding end of the protruding portion 1511. Accordingly, the sensor bracket 1510 may be integrally formed in an "┒" shape. A sensor coupling hole 1512a may be provided in the bending portion 1512.

[0218] The sensor 1520 may be coupled to the sensor bracket 1510. For example, the sensor 1520 may be coupled to the bending portion 1512 of the sensor bracket 1510. At this time, at least a part of the sensor 1520 may be set to penetrate through the sensor coupling hole 1512a. Accordingly, at least a part of the sensor 1520 may protrude forward of the bending portion 1512.

[0219] The sensor 1520 may recognize the contact of the pressure plate 1540. For example, when an external force is applied to the pressure plate 1540 to rotate the pressure plate 1540, the pressure plate 1540 may contact the sensor 1520. When contacting the pressure plate 1540, the sensor 1520 may transmit corresponding information to the control unit 1400. When receiving the information that the pressure plate 1540 has been contacted from the sensor 1520, as described above, the control unit 1400 may control the driving of at least one of the first leg massaging unit 1310 and the second leg massaging unit 1330. In addition, the control unit 1400 may send a warning signal to the user by driving the alarm unit.

[0220] The sensor 1520 may be set as a sensor using measurement means such as pressure, potential, and optics. As an example, the sensor 1520 may include: a sensor housing 1521; a contact portion 1522 provided in the sensor housing 1521 and detecting the contact with the pressure plate 1540; a fastening portion 1523 for fastening to the sensor bracket 1510; and an electrode terminal 1524 for electrically connecting to an external device.

[0221] When pressure is applied through the pressure plate 1540, the contact portion 1522 may slide inwardly of the sensor housing 1521. To this end, a separate elastic member for applying an elastic force to the contact portion 1522 may be provided inside the sensor housing 1521. When the contact portion 1522 slides inwardly of the sensor housing 1521 under pressure, the sensor 1520 may send a signal to the control unit 1400. Accordingly, as described above, the control unit 1400 may control the driving of at least one of the first leg massaging unit 1310 and the second leg massaging unit 1330, or may send a warning signal to the user through the alarm unit.

[0222] The fastening part 1523 can be set to be combined with the sensor bracket 1510. The fastening part 1523 can be made of an elastic material. When fastening the sensor 1520, it can be inserted into the sensor coupling hole 1512a formed in the sensor bracket 1510. In order to easily insert into the sensor coupling hole 1512a, the fastening part 1523 can include an inclined surface. The inclined surface can be set such that the distance from the rear to the front of the sensor 1520 increases with respect to the sensor housing 1521 while being fixed to the sensor housing 1521 at one end. In addition, in order to easily contact the sensor coupling hole 1512a, a flat surface can be provided at the other end of the inclined surface. The flat surface can contact the inner surface of the sensor coupling hole 1512a. When held by a user, the fastening part 1523 can be folded toward the sensor housing 1521 side. Therefore, when it is necessary to separate the sensor 1520, the user can separate the sensor 1520 from the sensor bracket 1510 by holding the fastening part 1523.

[0223] On the other hand, as long as the rotation or contact of the pressure plate 1540 can be recognized, the sensor 1520 can be replaced by various sensors general in the technical field to which the present utility model belongs. For example, the sensor 1520 may include at least one of a pressure sensor, an infrared sensor, an LED sensor, a touch sensor, and an electrode sensor.

[0224] The center support bracket 1530 can be disposed on both sides of the sensor bracket 1510. The center support bracket 1530 can be manufactured as a separate member from the sensor bracket 1510 or can be integrally manufactured with the sensor bracket 1510. Alternatively, after manufacturing the center support bracket 1530 and the sensor bracket 1510 as separate members, the center support bracket 1530 and the sensor bracket 1510 can also be combined by methods such as welding. The method of combining the center support bracket 1530 and the sensor bracket 1510 can be replaced by various methods general in the technical field to which the present utility model belongs. The pressure plate 1540 can be rotatably connected to the center support bracket 1530. The center support bracket 1530 can include a center fixing member 1531 and a center rotating member 1532.

[0225] For example, the center fixing member 1531 can include: a base portion 1531c; and side portions 1531d that project upward from both sides of the base portion 1531c. The base portion 1531c and the side portions 1531d can be formed by bending a single member. However, the base portion 1531c and the side portions 1531d can also be manufactured as separate members and then combined.

[0226] The base 1531c may form the bottom surface of the central fixing member 1531. At least one stopper 1531e may be provided on the base 1531c. The stopper 1531e may limit the angle of rotation of the pressure plate 1540 in a direction away from the sensor 1520. The stopper 1531e may penetrate the base 1531c and the end portion may protrude downward from the base 1531c. When a single stopper 1531e is provided, the stopper 1531e may be disposed in the central region of the base 1531c, and when multiple stoppers are provided, they may be disposed in at least one of the central region and the side regions of the base 1531c.

[0227] The position and structure of the stopper 1531e provided can be variously changed under the condition that the rotation angle of the pressure plate 1540 can be restricted. For example, the stopper 1531e may also be attached to the bottom surface of the base 1531c so that the entire stopper 1531e protrudes downward from the base 1531c. In addition, the stopper 1531e may be integrally manufactured with the base 1531c. In addition, the stopper 1531e may be provided on the pressure plate 1540.

[0228] The side portion 1531d may include a leg connection frame insertion groove 1531d-1. The leg connection frame 1131b may be inserted and joined to the leg connection frame insertion groove 1531d-1. The leg connection frame insertion groove 1531d-1 may be provided by cutting one end portion of the side portion 1531d facing the leg connection frame 1131b. The leg connection frame insertion groove 1531d-1 may be provided in a shape in which the inner surface is joined to the outer surface of the leg connection frame 1131b. When the leg connection frame 1131b is inserted into the leg connection frame insertion groove 1531d-1, the portion of the side portion 1531d in contact with the leg connection frame 1131b may be welded. However, the method of joining the side portion 1531d and the leg connection frame 1131b may be replaced by various methods common in the technical field to which the present utility model belongs.

[0229] The side portion 1531d may include a central rotating member insertion groove 1531d-2. The central rotating member 1532 may be rotatably hinge-joined to the central rotating member insertion groove 1531d-2. The central rotating member insertion groove 1531d-2 may be provided at various positions on the side portion 1531d, which are positions where the central rotating member 1532 can rotate on the upper portion of the side portion 1531d.

[0230] The side portion 1531d may include a pressure plate insertion groove 1531d-3. One side of the pressure plate 1540 may be rotatably hinge-joined to the pressure plate insertion groove 1531d-3. The pressure plate insertion groove 1531d-3 may be provided on the other side of the pressure plate 1540 to rotate upward (refer to Figure 16 ) or downward ( Figure 17The various positions of the side portion 1531d that come into contact with the sensor 1520 when rotating at an angle equal to or greater than a preset angle (see reference). For example, the pressure plate insertion groove 1531d-3 may be provided at the lower front side of the side portion 1531d (see reference Figure 16 ) or the upper front side (see reference Figure 17 ).

[0231] Any one of the side portions 1531d that protrude from both sides of the base portion 1531c may be provided with a fixing piece 1531d-4 that bends towards the other side portion 1531d. However, the fixing piece 1531d-4 may also be manufactured as a separate component and combined with the side portions 1531d on both sides. When the central rotating member 1532 rotates and its end contacts the fixing piece 1531d-4, the end of the central rotating member 1532 and the fixing piece 1531d-4 may be connected by a fastening member.

[0232] The side portion 1531d may include a central bushing receiving groove 1531d-5. The central bushings 1311, 1321 may be rotatably disposed in the central bushing receiving groove 1531d-5. For example, the central bushing receiving groove 1531d-5 may be provided by cutting the upper end of the side portion 1531d.

[0233] The central rotating member 1532 may be rotatably hinge-coupled to the side portion 1531d. The central rotating member 1532 may include a central bushing fixing groove 1532d. When the central rotating member 1532 rotates and is connected to the fixing piece 1531d-4 of the side portion 1531d, the central bushing fixing groove 1532d may rotatably support the central bushings 1311, 1321 together with the central bushing receiving groove 1531d-5.

[0234] The pressure plate 1540 may be rotatably hinge-coupled to the central support bracket 1530. The pressure plate 1540 may include an elastic member 1541. The elastic member 1541 may apply an elastic force to the pressure plate 1540 such that the free end of the pressure plate 1540 rotates in a direction away from the sensor 1520. The elastic member 1541 may be provided as various members that can apply an 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, both ends of the torsion spring may contact at least one of the pressure plate 1540 and the central support bracket 1530 when the pressure plate 1540 rotates.

[0235] In the case where the user's body or other object is not pinched between the leg massage unit 1300 or between the leg massage unit 1300 and the body massage unit 1100, the elastic member 1541 may simply prevent the user's body or other object from contacting the pressure plate 1540 and thus the pressure plate 1540 from rotating.

[0236] The pressure plate 1540 can rotate and 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 can rotate and contact the sensor 1520.

[0237] Figure 18 Parts (a) and (b) of [] show diagrams of the process of driving a safety sensor module according to an embodiment of the present invention.

[0238] Referring to Figure 18 In part (a) of [], due to the elastic force of the elastic member 1541, one end of the pressure plate 1540 can be set to be separated from the sensor 1520, and the other end can contact the stopper 1531e. Since the elastic force is continuously applied to the pressure plate 1540, if a specified external force is not applied for a specified time, one end of the pressure plate 1540 may not contact the sensor 1520.

[0239] Referring to Figure 18 In part (b) of [], when the user's body is clamped between the leg massage part 1300 and / or between the leg massage part 1300 and the body massage part 1100, and at least one of the leg massage part 1300 and the body massage part 1100 rotates, an external force F greater than the elastic force of the elastic member 1541 can be applied to the pressure plate 1540. In addition, as long as the clamping state is not released, the external force F can continuously act on the pressure plate 1540. In this case, the pressure plate 1540 can rotate, and one end can contact the sensor 1520. When the pressure plate 1540 contacts, the sensor 1520 can transmit the corresponding information to the control unit 1400. When receiving the information that the pressure plate 1540 has been contacted from the sensor 1520, the control unit 1400 can control the driving of at least one of the first leg massage part 1310, the second leg massage part 1330, and the body massage part 1100, or can drive the alarm part. Therefore, it is possible to prevent safety accidents that may occur due to the user's body being clamped between the leg massage part 1300 and / or between the leg massage part 1300 and the body massage part 1100.

[0240] Moreover, it is possible to prevent equipment failures and damages that may occur due to other objects other than the user's body being clamped between the leg massage part 1300 or between the leg massage part 1300 and the body massage part 1100.

[0241] Hereinafter, for the sake of convenience of description, the leg massage part 1300 is changed to the leg massage part 2000, the first leg massage part 1310 is changed to the first leg massage part 2000a, and the second leg massage part 1330 is changed to the second leg massage part 2000b.

[0242] Figure 19 FIG. is a diagram schematically showing a leg length adjustment module of the leg massage unit 2000. Figure 20 FIG. is a diagram for explaining the principle of length adjustment of the leg massage unit 2000. Figure 21 is an enlarged Figure 19 diagram of part B of Figure 22 is an enlarged Figure 19 diagram of part C of

[0243] Referring to Figure 19 , the massage apparatus 1000 may include a leg length adjustment module 2500 for adjusting the length of the leg massage unit 2000. At this time, the leg length adjustment module 2500 may adjust the length of the leg massage unit 2000 based on the control of the control unit 1400.

[0244] The leg length adjustment module 2500 may include a first leg length adjustment module 2500a and a second leg length adjustment module 2500b.

[0245] The first leg length adjustment module 2500a may be included in the first leg massage unit 2000a. For example, the first leg length adjustment module 2500a may be disposed behind the first leg massage unit 2000a. Specifically, the first leg length adjustment module 2500a may be disposed between behind the first leg massage unit 2000a and in front of the first leg angle adjustment module 1350a.

[0246] The first leg length adjustment module 2500a may adjust the length of the first leg massage unit 2000a by moving the position of the first leg massage unit 2000a. At this time, the first leg length adjustment module 2500a may adjust the length of the first leg massage unit 2000a based on the length of the user's one leg.

[0247] As an example, the first leg length adjustment module 2500a may adjust the length of the first leg massage unit 2000a by moving the first leg massage unit 2000a in at least one of the upper side (or upper side direction) and the lower side (or lower side direction) of the first leg massage unit 2000a. At this time, the upper side direction of the first leg massage unit 2000a may be a direction from the lower side of the first leg massage unit 2000a toward the upper side of the first leg massage unit 2000a, and the lower side direction of the first leg massage unit 2000a may be a direction from the upper side of the first leg massage unit 2000a toward the lower side of the first leg massage unit 2000a.

[0248] As another example, the first leg length adjustment module 2500a adjusts (or regulates) the distance between the first upper leg massage part 2000aa and the first lower leg massage part 2000ab of the first leg massage part 2000a by moving at least one of the first upper leg massage part 2000aa and the first lower leg massage part 2000ab of the first leg massage part 2000a in at least one direction among the upper side and the lower side of the first leg massage part 2000a, so that the length of the first leg massage part 2000a can be adjusted. At this time, the first upper leg massage part 2000aa can massage the upper part (for example, the calf part) of one side of the user's leg. For example, the first upper leg massage part 2000aa can include massage modules for massaging the upper part of the leg, such as air bags and rollers, in at least a part of the entire area of the first upper leg massage part 2000aa. The second lower leg massage part 2000ab can massage the lower part (for example, the foot) of the other side of the user's leg. For example, the second lower leg massage part 2000ab can include massage modules for massaging the lower part of the leg, such as air bags and rollers, in at least a part of the entire area of the second lower leg massage part 2000ab.

[0249] The second leg length adjustment module 2500b can be included in the second leg massage part 2000b. For example, the second leg length adjustment module 2500b can be arranged behind the second leg massage part 2000b. Specifically, the second leg length adjustment module 2500b can be arranged between the rear of the second leg massage part 2000b and the front of the second leg angle adjustment module 1350b.

[0250] The second leg length adjustment module 2500b can adjust the length of the second leg massage part 2000b by moving the position of the second leg massage part 2000b. At this time, the second leg length adjustment module 2500b can adjust the length of the second leg massage part 2000b based on the length of the other side of the user's leg.

[0251] As an example, the second leg length adjustment module 2500b can adjust the length of the second leg massage part 2000b by moving the second leg massage part 2000b in at least one direction among the upper side (or the upper side direction) and the lower side (or the lower side direction) of the second leg massage part 2000b. At this time, the upper side direction of the second leg massage part 2000b can be the direction from the lower side of the second leg massage part 2000b to the upper side of the second leg massage part 2000b, and the lower side direction of the second leg massage part 2000b can be the direction from the upper side of the second leg massage part 2000b to the lower side of the second leg massage part 2000b.

[0252] As another example, the second leg length adjustment module 2500b adjusts (or regulates) the distance between the second upper leg massage part 2000ba and the second lower leg massage part 2000bb of the second leg massage part 2000b by moving at least one of the second upper leg massage part 2000ba and the second lower leg massage part 2000bb of the second leg massage part 2000b in at least one direction of the upper side and the lower side, so that the length of the second leg massage part 2000b can be adjusted. At this time, the content of the above-mentioned first upper leg massage part 2000aa can be applied to the second upper leg massage part 2000ba, and the content of the above-mentioned first lower leg massage part 2000ab can be applied to the second lower leg massage part 2000bb.

[0253] In other words, each leg massage part (the first leg massage part 2000a, the second leg massage part 2000b) can adjust the length of the leg massage part (the first leg massage part 2000a, the second leg massage part 2000b) based on the length of each leg through the adjustment module of each leg massage part.

[0254] Specifically, referring to Figure 19 and Figure 20 , the adjustment modules (the first leg length adjustment module 2500a, the second leg length adjustment module 2500b) may include: lead screws 2510a, 2510b for adjusting the distance between the upper leg massage parts (the first upper leg massage part 2000aa, the second upper leg massage part 2000ba) and the lower leg massage parts (the first lower leg massage part 2000ab, the second lower leg massage part 2000bb); and leg length adjustment actuators 2520a, 2520b for providing power to the lead screws 2510a, 2510b.

[0255] According to a preferred embodiment, the lead screws 2510a, 2510b may be formed with threads on their outer surfaces, the leg frame 2210 may include a fixing member, the inner surface of which is formed to correspond to the lead screws 2510a, 2510b, and the lead screws 2510a, 2510b penetrate through the fixing member. In addition, the leg frame 2210 may be provided on the upper leg massage parts (the first upper leg massage part 2000aa, the second upper leg massage part 2000ba), and the lead screws 2510a, 2510b and the leg length adjustment actuators 2520a, 2520b may be provided on the lower leg massage parts (the first lower leg massage part 2000ab, the second lower leg massage part 2000bb).

[0256] The lead screws 2510a and 2510b can be rotated by means of the leg length adjustment actuators 2520a and 2520b. As the lead screws 2510a and 2510b rotate, they thread through the fixed member and can move up and down. As a result, the lower leg massage parts (the first lower leg massage parts 2000ab and 2000bb, the second lower leg massage parts 2000bb) can approach or move away from the upper leg massage parts (the first upper leg massage parts 2000aa and 2000ba) according to the rotation of the lead screws 2510a and 2510b. Thus, the distance between the upper leg massage parts (the first upper leg massage parts 2000aa and 2000ba) and the lower leg massage parts (the first lower leg massage parts 2000ab and 2000bb) can be adjusted. Therefore, the lengths of the first leg massage part 2000a and the second leg massage part 2000b can be adjusted.

[0257] Referring to Figure 21 , guide rails 2211a and 2211b can be formed on the inner sides of the leg frames 22l0a and 22l0b. In addition, the first leg massage part 2000a and the second leg massage part 2000b can include: guide rollers 2540a and 2540b that move along the guide rails 2211a and 2211b; and guide rods 2530a and 2530b that support the guide rollers 2540a and 2540b. At this time, one end of the guide rods 2530a and 2530b can be connected to (the first lower leg massage parts 2000ab and 2000bb, the second lower leg massage parts 2000bb). Therefore, as the lead screws 2510a and 2510b rotate, the guide rods 2530a and 2530b and the guide wheels 2540a and 2540b can move in the same direction as the lower leg massage parts (the first lower leg massage parts 2000ab and 2000bb).

[0258] On the other hand, the guide rollers 2540a and 2540b can move along the guide rails 2211a and 2211b. Therefore, the guide rollers 2540a and 2540b can guide the paths of (the first lower leg massage parts 2000ab and 2000bb) so that they move in an appropriate direction. Therefore, during the movement of (the first lower leg massage parts 2000ab and 2000bb), the leg massage parts (the first leg massage part 2000a and the second leg massage part 2000b) on both sides can not shake.

[0259] On the other hand, the guide rails 2211a and 2211b can be formed on a part of the inner side of the leg frame 2210. Referring to Figure 21, guide rails 2211a and 2211b are formed only on a part of the inner side of the leg frame 2210, and claws are formed on the remaining part, so that the movement of the guide rollers 2540a and 2540b can be blocked. Therefore, the lower leg massage parts (the first lower leg massage parts 2000ab and the second lower leg massage parts 2000bb) can be blocked from moving to the extreme points, and the problem that the lower leg massage parts (the first lower leg massage parts 2000ab and the second lower leg massage parts 2000bb) are completely separated from the upper leg massage parts (the first upper leg massage parts 2000aa and the second upper leg massage parts 2000ba) can be prevented.

[0260] On the other hand, in order to more appropriately guide the movement of the guide rods 2530a and 2530b, the leg massage part 2000 may further include guide wheels 2551a and 2551b and guide wheel brackets 2552a and 2552b for accommodating and supporting the guide wheels 2551a and 2551b. Refer to Figure 22 , at least one of the guide wheels 2551a and 2551b may be provided inside the guide wheel brackets 2552a and 2552b. The outer surfaces of the guide wheels 2551a and 2551b may be formed to be recessed inward, and the guide rods 2530a and 2530b may be arranged to be inserted corresponding to the recessed areas. Therefore, when the guide rods 2530a and 2530b move up and down, the guide wheels 2551a and 2551b can support the guide rods 2530a and 2530b so that the guide rods 2530a and 2530b do not deviate from the movement path. As a result, the guide wheels 2551a and 2551b can support the guide rods 2530a and 2530b so that the guide rods 2530a and 2530b do not shake during the movement, and can guide the path so that the guide rods 2530a and 2530b move in an appropriate direction. Therefore, the lower leg massage parts (the first lower leg massage parts 2000ab and the second lower leg massage parts 2000bb) can also move in an appropriate direction through the guide rods 2530a and 2530b and can not shake.

[0261] Figure 23 is a view showing the foot massage part 2600 according to an embodiment of the present invention.

[0262] The lower leg massage parts (the first lower leg massage parts 2000ab and the second lower leg massage parts 2000bb) may include foot massage parts (the first foot massage part 2610 and the second foot massage part 2630) on one side. Preferably, the foot massage parts (the first foot massage part 2610 and the second foot massage part 2630) may be provided at the lowermost end or the bottom of the lower leg massage parts (the first lower leg massage parts 2000ab and the second lower leg massage parts 2000bb).

[0263] The foot massage part (the first foot massage part 2610 and the second foot massage part 2630) may include at least one foot massage module (or a massage unit for massaging the feet) and a foot massage actuator (or a foot driving part) for driving at least one foot massage module. For example, the first leg massage part 2000a may include the first foot massage part 2610 disposed in a region corresponding to the sole of one side leg of the user. The second leg massage part 2000b may include the second foot massage part 2630 disposed in a region corresponding to the sole of the other side leg of the user.

[0264] The first foot massage part 2610 may include at least one foot massage module among the first foot massage module 2612 and the second foot massage module 2613. The first foot massage module 2612 and the second foot massage module 2613 are respectively disposed (or configured) in front of and behind the first foot massage part 2610, so as to provide massage to the sole of one side leg of the user as a whole. In addition, the first foot massage part 2610 may include first foot massage actuators 2611, 2613 for driving at least one foot massage module. The first foot massage actuators 2611, 2613 are disposed in front of the first foot massage part 2610 and in front of the first foot massage module 2612, so as to drive at least one foot massage module. At this time, the front of the first foot massage part 2610 and the front of the first foot massage module 2612 may be a region corresponding to the toes of one side leg in the entire region of the first foot massage part 2610.

[0265] The second foot massage part 2630 may include at least one foot massage module among the third foot massage module 2632 and the fourth foot massage module 2633. For example, the third foot massage module 2632 and the fourth foot massage module 2633 are respectively disposed (or configured) in front of and behind the second foot massage part 2630, so as to provide massage to the sole of the other side leg of the user as a whole. In addition, the second foot massage part 2630 may include a second foot massage actuator 2631 for driving at least one foot massage module. The second foot massage actuator 2631 is disposed in front of the second foot massage part 2630 and in front of the third foot massage module 2632, so as to drive at least one foot massage module. At this time, the front of the second foot massage part 2630 and the front of the third foot massage module 2632 may be a region corresponding to the toes of the other side leg in the entire region of the second foot massage part 2630.

[0266] As described above, the first foot massage part 2610 and the second foot massage part 2630 include two foot massage modules and one foot massage actuator, but are not limited thereto. For example, the first foot massage part and the second foot massage part may include a plurality of (for example, three or more) foot massage modules, such as Figure 23As shown, each foot massage module can be configured in a straight line. At this time, a straight line can be a line passing through the sole of the foot. The first foot massage unit and the second foot massage unit each include a single foot massage actuator, and all the multiple foot massage modules can be driven by the single foot massage actuator.

[0267] On the other hand, at least one protrusion can be formed on the surface of the foot massage module. Therefore, the foot massage module can provide massage to the sole of the user's foot by rotation.

[0268] Alternatively, the foot massage module can be a roller with an arcuate surface. Therefore, the foot massage module can provide massage to the sole of the user's foot by rotation.

[0269] On the other hand, as an alternative embodiment, a cam can be installed on the foot massage actuator. Therefore, the foot massage unit 2600 can use the cam to provide acupressure massage to the user's toes without rolling massage. In addition, compared with the case of separately setting the foot massage actuator, the space efficiency can be improved by installing the cam on the foot massage actuator.

[0270] Figure 24 It is a diagram for explaining the pinch prevention sensor S in the leg massage unit 2000 according to an embodiment of the present invention.

[0271] At least one pinch prevention sensor S (or safety sensor) can be provided at least at one position among the side, rear, and between the upper leg massage units (the first upper leg massage unit 2000aa, the second upper leg massage unit 2000ba) and the lower leg massage units (the first lower leg massage unit 2000ab, the second lower leg massage unit 2000bb) of the leg massage unit 2000. At this time, the pinch prevention sensor S can be a sensor for identifying that a part of the user's body is caught between the leg massage units (the first leg massage unit 2000a, the second leg massage unit 2000b).

[0272] At this time, the provided pinch prevention sensor S can be a capacitive touch sensor, but it is not limited thereto.

[0273] In the case where the pinch prevention sensor S is attached to the side of the leg massage unit 2000, when the leg massage unit 2000 rotates, it can be recognized that at least a part of the user's body is caught between the leg massage units (the first leg massage unit 2000a, the second leg massage unit 2000b) on both sides. Or, when the leg massage unit 2000 rotates, it can be recognized that at least a part of the user's body is caught between the leg massage unit 2000 and the body massage unit 1100.

[0274] When the pinch prevention sensor S is attached to the rear of the leg massage unit 2000, it is possible to recognize that a part of the user's body is pinched behind the leg massage unit 2000 when the leg massage unit 2000 rotates.

[0275] When the pinch prevention sensor S is attached between the upper leg massage units (the first upper leg massage unit 2000aa and the second upper leg massage unit 2000ba) and the lower leg massage units (the first lower leg massage unit 2000ab and the second lower leg massage unit 2000bb), it is possible to recognize that a part of the user's body is pinched between the upper leg massage units (the first upper leg massage unit 2000aa and the second upper leg massage unit 2000ba) and the lower leg massage units (the first lower leg massage unit 2000ab and the second lower leg massage unit 2000bb) when adjusting the distance between the upper leg massage units (the first upper leg massage unit 2000aa and the second upper leg massage unit 2000ba) and the lower leg massage units (the first lower leg massage unit 2000ab and the second lower leg massage unit 2000bb).

[0276] Therefore, during the rotation of the leg massage unit 2000, when the user's body is pinched at a specific position of the massage device 100, the pinch prevention sensor S can recognize this situation. Thus, the massage device 100 can stop, thereby preventing safety accidents.

[0277] On the other hand, the pinch prevention sensor S can be formed to extend in a long strip shape. That is, the pinch prevention sensor S can be a linear sensor.

[0278] When the leg massage unit 2000 rotates or adjusts its length, since it is impossible to determine where on the leg massage unit 2000 a person's body will be pinched, when the pinch prevention sensor S is formed to extend in the length direction, the area where it can sense whether the user's body contacts becomes wider. Therefore, the user can use the massage device 100 more safely.

[0279] As an alternative embodiment, the pinch prevention sensor S may be provided on the upper leg massage unit (the first upper leg massage unit 2000aa, the second upper leg massage unit 2000ba) and the lower leg massage unit (the first lower leg massage unit 2000ab, the second lower leg massage unit 2000bb) respectively. At least one pinch prevention sensor S may be provided on each surface. For example, the pinch prevention sensor S may be provided on both side surfaces of the upper leg massage unit (the first upper leg massage unit 2000aa, the second upper leg massage unit 2000ba), and may also be provided on the left and right sides behind the upper leg massage unit (the first upper leg massage unit 2000aa, the second upper leg massage unit 2000ba). In addition, the pinch prevention sensor S may be provided on the surface between the upper leg massage unit (the first upper leg massage unit 2000aa, the second upper leg massage unit 2000ba) and the lower leg massage unit (the first lower leg massage unit 2000ab, the second lower leg massage unit 2000bb). In addition, the pinch prevention sensor S may be provided on both side surfaces of the lower leg massage unit (the first lower leg massage unit 2000ab, the second lower leg massage unit 2000bb).

[0280] Therefore, during the operation of the massage device 100, even if a part of the user's body such as the leg is pinched at any position adjacent to the leg massage unit 2000, this situation can be recognized.

[0281] Although not shown in the figure, the leg massage unit 2000 may further include a sensor for controlling the length of the leg massage unit 2000.

[0282] As an embodiment, the leg massage unit 2000 may include at least one limit sensor in the leg frame 2210. The limit sensor may be a sensor for determining the length adjustment limit 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.

[0283] By providing the limit sensor, the upper leg massage unit (the first upper leg massage unit 2000aa, the second upper leg massage unit 2000ba) and the lower leg massage unit (the first lower leg massage unit 2000ab, the second lower leg massage unit 2000bb) can be prevented from separating beyond a certain limit, safety accidents can be prevented, and the lower leg massage unit (the first lower leg massage unit 2000ab, the second lower leg massage unit 2000bb) can be prevented from completely separating from and detaching from the upper leg massage unit (the first upper leg massage unit 2000aa, the second upper leg massage unit 2000ba).

[0284] As another embodiment, the leg massage unit 2000 may include an encoder. Thus, by using the encoder to identify the distances between the upper leg massage units (the first upper leg massage unit 2000aa and the second upper leg massage unit 2000ba) and the lower leg massage units (the first lower leg massage unit 2000ab and the second lower leg massage unit 2000bb), the length adjustment limit of the leg massage unit 2000 can be determined. That is, by the encoder identifying the distances between the upper leg massage units (the first upper leg massage unit 2000aa and the second upper leg massage unit 2000ba) and the lower leg massage units (the first lower leg massage unit 2000ab and the second lower leg massage unit 2000bb), when a certain critical point is reached, the relative movement between the upper leg massage units (the first upper leg massage unit 2000aa and the second upper leg massage unit 2000ba) and the lower leg massage units (the first lower leg massage unit 2000ab and the second lower leg massage unit 2000bb) can be stopped.

[0285] As an embodiment, the leg massage units (the first leg massage unit 2000a and the second leg massage unit 2000b) may further include a measurement sensor unit for measuring the leg length of the user. For example, the measurement sensor unit may include at least one of a first measurement sensor and a second measurement sensor. The first leg massage unit 2000a may include a first measurement sensor for measuring the length of one leg, and the second leg massage unit 2000b may include a second measurement sensor for measuring the length of the other leg.

[0286] Preferably, each measurement sensor may include at least one sensor (or sub-measurement sensor) of a first sensor (or first sub-measurement sensor) and a second sensor (or second sub-measurement sensor) for measuring the leg length of the user.

[0287] For example, the first sensor may be a capacitive touch sensor. The first sensor can be used to roughly measure the leg length of the user. Thus, the leg length of the user can be measured by the first sensor, and the length of the leg massage units (the first leg massage unit 2000a and the second leg massage unit 2000b) can be adjusted correspondingly.

[0288] The first sensor can measure the leg length by identifying the body contact of the user. Therefore, the first sensor can measure the leg length of the user according to whether the user's body is in contact, and the massage device 100 can adjust the length of the leg massage units (the first leg massage unit 2000a and the second leg massage unit 2000b) based on this. Although the accuracy is reduced, the length of the leg massage units (the first leg massage unit 2000a and the second leg massage unit 2000b) can be adjusted quickly and roughly.

[0289] In order to accurately measure the lengths of the leg massage parts (the first leg massage part 2000a and the second leg massage part 2000b), the leg massage parts (the first leg massage part 2000a and the second leg massage part 2000b) according to the present utility model may further include a second sensor.

[0290] For example, the second sensor may be a light sensor or a load sensor. The second sensor can be used to accurately measure the length of the user's leg. Therefore, after the massage device 100 roughly measures the length of the user's leg by using the first sensor and correspondingly adjusts the lengths of the leg massage parts (the first leg massage part 2000a and the second leg massage part 2000b), it can accurately measure the length of the user's leg by using the second sensor and correspondingly adjust the lengths of the leg massage parts (the first leg massage part 2000a and the second leg massage part 2000b).

[0291] Figure 25 FIG. is a diagram for explaining a light sensor in a leg massage part according to an embodiment of the present utility model. Figure 26 is an enlarged Figure 25 diagram of part D.

[0292] Referring to Figure 25 and Figure 26 , as an embodiment, the second sensor may be a light sensor PS. Preferably, it may be a mechanical light sensor. Thus, as described above, when using the light sensor PS, the length of the user's leg can be measured more accurately compared to the case of only using the first sensor. In addition, the light sensors PS are respectively arranged on the leg massage parts on both sides, so that the lengths of the user's legs on both sides can be measured more accurately.

[0293] For example, the light sensor PS may be located on the lower side of the leg massage parts (the first leg massage part 2000a and the second leg massage part 2000b). Therefore, the light sensor PS can measure the length of the user's leg more accurately. That is, referring to Figure 26 , when the light sensors PS are respectively located on the lower sides of the leg massage parts (the first leg massage part 2000a and the second leg massage part 2000b) on both sides and the leg massage parts (the first leg massage part 2000a and the second leg massage part 2000b) move, the disc member rotates according to the movement, and the light receiving degree that changes due to the rotation of the disc member is measured, so that the length of the user's leg can be accurately measured.

[0294] However, it is not limited thereto, and other types of light sensors PS may be used or the length of the user's leg may be measured according to the principle of driving the existing light sensor PS.

[0295] As another embodiment, the second sensor may measure the leg length by measuring the load applied to the user's leg.

[0296] For example, the control unit 1400 of the massage device 100 can adjust the distance between the upper leg massage units (the first upper leg massage unit 2000aa and the second upper leg massage unit 2000ba) and the lower leg massage units (the first lower leg massage unit 2000ab and the second lower leg massage unit 2000bb), and identify the length of the leg massage units (the first leg massage unit 2000a and the second leg massage unit 2000b) when a load of a preset size is applied to the second sensor as the leg length of the user. Therefore, the massage device 100 can finely adjust the distance between the upper leg massage units (the first upper leg massage unit 2000aa and the second upper leg massage unit 2000ba) and the lower leg massage units (the first lower leg massage unit 2000ab and the second lower leg massage unit 2000bb), identify the distance of the leg massage units (the first leg massage unit 2000a and the second leg massage unit 2000b) when a load of a preset certain size is applied to the second sensor as the leg length of the user, and in this case, can adjust the length of the leg massage units (the first leg massage unit 2000a and the second leg massage unit 2000b) corresponding to the leg length of the user.

[0297] On the other hand, the first sensor and the second sensor can be located below the leg massage units (the first leg massage unit 2000a and the second leg massage unit 2000b). Preferably, it can be set at a position corresponding to the bottom of the user's foot. Therefore, the leg length of the user can be accurately measured according to the length change of the leg massage units (the first leg massage unit 2000a and the second leg massage unit 2000b).

[0298] Hereinafter, the operation method of the above massage device 100 will be described in detail.

[0299] The operation method of the massage device 100 according to the present utility model may include: receiving an operation input by the user; identifying an operation of body information about at least a part of the user's body; adjusting the operation of the massage device based on the body information; and providing a massage to the user by using the adjusted massage device.

[0300] Figure 27 It is a diagram for explaining the stretching mode and the exercise mode provided by the massage device according to an embodiment of the present utility model.

[0301] The massage device 1000 can provide a stretching mode for stretching the user's body and a leg rehabilitation mode (or cycling mode) for exercising the user's legs. At this time, the stretching mode can be a mode for stretching at least one of the user's legs, waist, and hips (e.g., the gluteal region). The cycling mode can be a mode used by a user with normal legs for leg exercise, or a mode used by a user with abnormal legs due to various injuries such as knee injuries for leg rehabilitation.

[0302] For example, the stretching mode may include at least one stretching mode such as an iliopsoas stretching mode (or iliopsoas relaxation mode) for stretching the iliopsoas muscle of the leg, a hamstring stretching mode (or hamstring relaxation mode) for stretching the hamstring of the leg, a waist stretching mode (or rolling stretching mode) for stretching the waist, and a piriformis stretching mode (piriformis relaxation mode) for stretching the piriformis muscle of the hip.

[0303] Specifically, the control unit 1400 can execute each stretching mode and / or cycling mode based on the user's response, or automatically execute each stretching mode and / or cycling mode. At this time, the user's response can be a response (or signal) for executing the stretching mode and / or cycling mode.

[0304] The control unit 1400 can provide each stretching mode and / or cycling mode to the user by controlling the operation of the massage device 1000 according to a massage map for each stretching mode and / or cycling mode. At this time, the massage map can be preset and stored in the memory 1430 according to various objects. The objects can be users using the massage device, managers, and / or staff of various enterprises such as manufacturers, sales companies, distributors, and developers of the massage device, and doctors.

[0305] As an example, the control unit 1400 can provide the iliopsoas stretching mode to the user by controlling the operation of the massage device 1000 according to the massage map of the iliopsoas stretching mode. Thus, the control unit 1400 relaxes the iliopsoas muscle by stretching the iliopsoas muscle of the user, thereby stretching the bent waist and reducing the excessive pressure transmitted to the lumbar vertebra, and thus can relieve low back pain.

[0306] As another example, the control unit 1400 can provide the hamstring stretching mode to the user by controlling the operation of the massage device 1000 according to the massage map of the hamstring stretching mode. Thus, the control unit 1400 relaxes the hamstring by stretching the hamstring of the user, thereby preventing muscle shortening and injury.

[0307] As another example, the control unit 1400 controls the operation of the massage device 1000 according to the massage map of the lumbar stretching mode, so as to provide the lumbar stretching mode to the user. Thus, the control unit 1400 can relax the muscles around the lumbar vertebra by stretching the user's waist, and thus can reduce the lumbar pain by enhancing the activity of the muscles around the lumbar vertebra.

[0308] As another example, the control unit 1400 controls the operation of the massage device 1000 according to the massage map of the piriformis stretching mode, so as to provide the piriformis stretching mode to the user. Thus, the control unit 1400 can relax the muscles around the buttocks (or piriformis) by stretching the user's buttocks (or piriformis), thereby reducing pain in the waist and buttocks, leg numbness, sciatica, etc., and thus can improve the hip joint activity of the lower body.

[0309] The control unit 1400 controls the operation of the massage device 1000 according to the massage map of the cycling mode, so as to provide the cycling mode to the user. Thus, the massage device 1000 can guide the normal leg to maintain a healthy state by exercising the normal leg, and guide the abnormal leg to recover to a healthy state by performing rehabilitation exercises on the abnormal leg. The massage device 1000 performs exercises (or rehabilitates the legs) on the legs by repeatedly moving the joints to maintain and enhance the flexibility and activity of the joints (pelvis, knees, ankles), thereby preventing joint contracture. In other words, the cycling mode can be a leg exercise mode and can also be a leg rehabilitation mode (or knee rehabilitation mode).

[0310] Figure 28 Illustrating for explaining Figure 27 A diagram showing an example of the massage mode shown, Figure 29 Illustrates an example of the tilting operation of the control unit according to an embodiment of the present invention.

[0311] Referring to Figure 28 and Figure 29 , the control unit 1400 can tilt the massage device 1000 (operation S2810), and can provide the stretching mode and / or the exercise mode to the user in the state where the massage device 1000 is tilted (operation S2830).

[0312] First, the control unit 1400 can tilt the massage device 1000 (operation S2810) by tilting the body massage unit 1100 backward with respect to the massage device 1000 and tilting (or rotating) each leg massage unit upward with respect to the massage device 1000. The tilted massage device 1000 can be in a state where the body massage unit 1100 is tilted backward with respect to the massage device 1000 and the leg massage unit 2000 is rotated upward with respect to the massage device 1000.

[0313] During the period when the control unit 1400 tilts the leg massage unit, it can adjust the length of each leg massage unit according to the length of each leg. Since the length adjustment operation of each leg massage unit is the same as described above, detailed description thereof is omitted.

[0314] After that, the control unit 1400 can provide the stretching mode and / or the exercise mode to the user by controlling the operation of the massage device 1000 according to the stretching mode and / or the exercise mode in the tilted state of the massage device 1000 (operation S2830). For example, the control unit 1400 can perform operations corresponding to the stretching mode and / or the exercise mode in the tilted state of the massage device 1000.

[0315] Thereby, the control unit 1400 ensures the space for stretching the user's legs and the space for moving the user's legs by tilting the massage device 1000, thereby eliminating the space limitations for stretching the user's legs and the space limitations for leg movement, so that the leg stretching effect and the leg movement effect can be increased.

[0316] In addition, the control unit 1400 can provide a relaxation massage for relaxing the user's body through a massage unit (for example, at least one of the body massage unit 1100, the arm massage unit 1200, and the leg massage unit 2000) in the tilted state of the massage device 1000, and then provide the stretching mode and / or the exercise mode. At this time, the relaxation massage can be a massage with a preset massage intensity and speed. For example, the relaxation massage can be provided at the average massage intensity and the average massage speed among the massage intensities and speeds that the massage device 1000 can provide, or can be provided at the lowest massage intensity and the lowest massage speed. Thereby, the control unit 1400 prevents injuries due to the stretching mode and / or the exercise mode by relaxing the user's body, so that the leg stretching effect and the leg movement effect can be increased.

[0317] As described above, after tilting the massage device 1000 and providing the relaxation massage, the control unit 1400 provides the stretching mode and / or the cycling mode to the user, but is not limited thereto. For example, the control unit 1400 can provide the stretching mode and / or the exercise mode in a state of performing at least one of the operation of tilting the massage device 1000 and the operation of providing the relaxation massage.

[0318] Figure 30 Illustrated for explaining Figure 27 The flowchart of the piriformis stretching mode shown.

[0319] The control unit 1400 controls the operation of the massage device 1000 through actions corresponding to the piriformis stretching mode, thereby being able to provide the piriformis stretching mode to the user.

[0320] First, the control unit 1400 increases the length of either the first leg massaging unit 2000a or the second leg massaging unit 2000b through the leg length adjustment module 2500, thereby stretching the user's leg (operation S3010).

[0321] When increasing the length of either leg massaging unit, the control unit 1400 can fix the user's leg by inflating the airbag of either leg massaging unit. For example, the control unit 1400 can inflate the leg airbag included in at least one of the upper leg massaging part and the lower leg massaging part of either leg massaging unit. Specifically, the control unit 1400 can first inflate the foot airbag (such as at least one of the first and second side foot airbags, etc.) included in the lower leg massaging part of either leg massaging unit, and then inflate the calf airbag (such as at least one of the first and second sub-calf airbags, etc.) included in the upper leg massaging part of either leg massaging unit.

[0322] As described above, when increasing the length of either leg massaging unit, the control unit 1400 inflates the airbag of either leg massaging unit, but is not limited thereto. For example, the control unit 1400 can also increase the length of either leg massaging unit after inflating the airbag of either leg massaging unit.

[0323] Thereby, the control unit 1400 can pull (Tracting) the leg of the stretching object to fully stretch (extension) the piriformis muscle of the leg, and the leg of the stretching object is the leg corresponding to either the leg massaging unit on one side or the other side of the user's leg. At this time, the control unit 1400 pulls the leg of the stretching object by precisely grasping the lower part of the leg of the stretching object, so that compared with the case where the lower part of the leg of the stretching object is not fixed, the leg of the stretching object can be stretched more precisely. In addition, the control unit 1400 can improve the stretching effect of the leg of the stretching object by further grasping the upper part of the leg of the stretching object and continuously pulling the leg of the stretching object.

[0324] The control unit 1400 can move the massage module 1110 to the user's buttocks to provide massage to the user's buttocks (operation S3030). For example, the control unit 1400 can move the massage module 1110 to the area corresponding to the user's buttocks in the overall area of the main frame 1130. The control unit 1400 can project the massage module 1110 moved to the user's buttocks in the forward direction of the massage module 1110 to massage the user's buttocks. At this time, the forward direction of the massage module 1110 can be the direction in which the massage module 1110 approaches the user's body. In other words, the control unit 1400 can provide acupressure massage to the user's buttocks through the massage module 1110.

[0325] Accordingly, the control unit 1400 can provide massage to the piriformis muscle stretched by the massage module 1110, thereby sufficiently relaxing the piriformis muscle.

[0326] Figure 31 A diagram for explaining Figure 30 the operation of the piriformis muscle stretching mode shown.

[0327] After the control unit 1400 obtains the user's shoulder position through the massage module 1110, the control unit 1400 can tilt the massage device 1000 (or the control unit 1400 can obtain the user's shoulder position through the massage module 1110 after tilting the massage device 1000 (Motion 1A). At this time, as described above, when the control unit 1400 tilts the massage device 1000 (or after performing the tilting action), the control unit 1400 can adjust the length of each leg massage unit according to the length of each leg.

[0328] After performing Motion 1A, the control unit 1400 can increase 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 in the state where the massage device 1000 is tilted (Motion 1B).

[0329] First, before increasing the length of any one of the leg massage units, the control unit 1400 can adjust (or change) the angle of any one of the leg massage units through the leg angle adjustment module 1350 in the state where the massage device 1000 is tilted (Motion 1B_l).

[0330] For example, the control unit 1400 can operate (or drive) the leg angle adjustment module corresponding to any one of the leg massage units among the first leg angle adjustment module 1350a and the second leg angle adjustment module 1350b to adjust the angle of any one of the leg massage units.

[0331] Specifically, the control unit 1400 can tilt any one of the leg massage units in either the clockwise direction or the counterclockwise direction through the leg angle adjustment module corresponding to any one of the leg massage units, thereby adjusting the angle of any one of the leg massage units. At this time, the control unit 1400 can make the other leg angle adjustment module different from the leg angle adjustment module corresponding to any one of the leg massage units among the first leg angle adjustment module 1350a and the second leg angle adjustment module 1350b not operate. Accordingly, the control unit 1400 can fix the position of the other leg massage unit different from any one of the first leg massage unit 2000a and the second leg massage unit 2000b.

[0332] As an example, the control unit 1400 can maximize the angle of any one of the leg massage units by extending the length of the leg angle adjustment module corresponding to any one of the leg massage units to the maximum, so that any one of the leg massage units rises to the highest position (operation lB_la).

[0333] As another example, the control unit 1400 can minimize the angle of any one of the leg massage units by shortening the length of the leg angle adjustment module corresponding to any one of the leg massage units to the minimum, so that any one of the leg massage units descends to the lowest position (operation lB_lb).

[0334] Thus, the control unit 1400 can flex the user's hip joint before extending the user's legs, thereby preventing physical injury caused by extending the user's legs.

[0335] After that, before increasing the length of any one of the leg massage units, the control unit 1400 can move the massage module 1110 to a position corresponding to the user's buttocks while adjusting the angle of any one of the leg massage units, and massage the user's buttocks through the massage module 1110 (operation 1B_2).

[0336] For example, the control unit 1400 can predict the position of the user's buttocks based on the position of the user's shoulders. The control unit 1400 can move the massage module 1110 to the user's buttocks based on the predicted position of the user's buttocks, thereby arranging the massage module 1110 at 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 thereto. For example, the control unit 1400 can move the massage module 1110 based on a preset position of the user's buttocks.

[0337] The control unit 1400 can provide massage to the user's buttocks through the massage module 1110 arranged at the user's buttocks. At this time, the massage can be various massages for relieving the tension of the user's buttocks (for example, acupressure massage, kneading massage, and compound massage, etc.), but for the convenience of description below, it is assumed to be a tapping massage. The tapping massage can be preset to various intensities and speeds that provide a soft massage feeling, for example, provided at the lowest intensity and the lowest speed among the massage intensities and speeds that the massage module 1110 can provide, or provided at an average intensity and an average speed, etc.

[0338] Thus, the control unit 1400 can prevent the user from being injured and the side effects caused by piriformis muscle stretching by providing a massage that relieves the tension of the buttocks muscles before stretching and relaxing the muscles of the user's buttocks (for example, the piriformis muscle).

[0339] As described above, the control unit 1400 moves the massage module 1110 while adjusting the angle of any one of the leg massage units, but is not limited thereto. For example, the control unit 1400 may also move the massage module 1110 when adjusting the angle of any one of the leg massage units, or may adjust the angle of any one of the leg massage units after moving the massage module 1110 (or while moving the massage module 1110).

[0340] Finally, after ending the operation 1B_2, the control unit 1400 may increase the length of any one of the leg massage units through the leg length adjustment module 2500 (operation 1B_3). At this time, the control unit 1400 may stop the operation of the massage module 1110 and end the operation of operation 1B_2. The control unit 1400 may move the massage module 1110 to the maximum extent to the rear of the massage module 1110 and then stop the massage module 1110 before stopping the operation of the massage module 1110.

[0341] For example, the control unit 1400 may operate (or drive) the leg length adjustment module corresponding to any one of the leg massage units among the first leg length adjustment module 2500a and the second leg length adjustment module 2500b to increase the length of any one of the leg massage units. At this time, as described above, the control unit 1400 may inflate the airbag of any one of the leg massage units.

[0342] Specifically, the control unit 1400 may move any one of the leg massage units in the lower direction of any one of the leg massage units through the leg length adjustment module corresponding to any one of the leg massage units, thereby increasing the length of any one of the leg massage units. At this time, the control unit 1400 may not operate the leg length adjustment module different from the leg length adjustment module corresponding to any one of the leg massage units among the first leg length adjustment module 2500a and the second leg length adjustment module 2500b. Thereby, the control unit 1400 may fix the length of the other leg massage unit different from any one of the first leg massage unit 2000a and the second leg massage unit 2000b.

[0343] Hereinafter, the leg length adjustment operation will be described in detail.

[0344] The control unit 1400 moves any one of the leg massage units in the lower direction of any one of the leg massage units based on the reference length for increasing the length of any one of the leg massage units, thereby increasing the length of any one of the leg massage units.

[0345] For example, the reference length is a reference indicating the degree of pulling the leg of the stretching object, and may refer to the moving length (or moving distance) of moving any one leg massage part in the downward direction of any one leg massage part. The reference length is a length that can fully stretch the leg of the stretching object, and can be preset and stored in the memory 1430 by various objects. For example, the reference length can be set differently, such as about 5 cm to 10 cm, etc.

[0346] As described above, the reference length can be preset, but is not limited thereto. For example, the control unit 1400 can determine the customized reference length customized by the user as the reference length based on the length of the leg corresponding to any one leg massage part of the user's one leg and the other leg. Specifically, the memory 1430 can store a matching table in which each arbitrary leg length and each arbitrary reference length match each other. The control unit 1400 can compare the length of the user's leg with the matching table, and determine an arbitrary reference length corresponding to the length of the leg among the arbitrary reference lengths included in the matching table as the customized reference length. The control unit 1400 can determine the customized reference length as the reference length for adjusting (or increasing) the length of any one leg massage part. The control unit 1400 can increase the length of any one leg massage part based on the reference length customized by the user.

[0347] As described above, the control unit 1400 increases the length of any one leg massage part after finishing the massage action of massaging the user's buttocks, that is, action 1B_2, but is not limited thereto. For example, the control unit 1400 can increase the length of any one leg massage part when massaging at least a part of the user's body after finishing action 1B_2.

[0348] Specifically, the control unit 1400 can change the position of the massage module 1110 and provide massage to at least a part of the user's body after finishing action 1B_2. At this time, the control unit 1400 can provide massage to the body part other than the user's buttocks in the user's body part through the massage module 1110. The control unit 1400 can increase the length of any one leg massage part after providing massage through the massage module 1110 or when providing massage.

[0349] In addition, when the control unit 1400 increases the length of any one leg massage part, it can inflate the pelvic airbag of the body massage part 1100 to a preset inflation degree to fix the user's pelvis. At this time, the pelvic airbag can be arranged in the area corresponding to the user's pelvis in the entire area of the massage device 1000, and this area is on both sides of the area where the user sits.

[0350] As described above, when the control unit 1400 increases the length of any one of the leg massage units, the pelvic airbag expands, but it is not limited thereto. For example, the control unit 1400 may expand the pelvic airbag before increasing the length of any one of the leg massage units.

[0351] Thus, the control unit 1400 fixes the user's legs and pelvis and stretches the target leg to be stretched, and can stretch the target leg to be stretched more precisely compared to the case where the user's pelvis is not fixed, thereby improving the stretching effect on the target leg to be stretched.

[0352] As described above, the control unit 1400 sequentially executes actions lB_l, 1B_2, and 1B_3, but it is not limited thereto. For example, the control unit 1400 may execute by adjusting the action sequence (or randomly) of actions 1B_1, 1B_2, and 1B_3, or may execute actions 1B_1, 1B_2, and 1B_3 simultaneously.

[0353] When executing action 1B, the control unit 1400 may provide massage to the user's buttocks through the massage module 1110 (action 1C). At this time, when the operation of the massage module 1110 stops, the control unit 1400 may drive the massage module 1110, and when the position of the massage module 1110 is not the position corresponding to the user's buttocks, the control unit 1400 may move the massage module 1110 to the user's buttocks and provide massage to the user's buttocks.

[0354] First, the control unit 1400 protrudes the massage module 1110 forward based on the reference intensity for massaging the user's buttocks, so that the user's buttocks can be massaged (action 1C_1). At this time, the reference intensity is a reference representing the massage intensity for pressing the user's buttocks, and may be the protruding degree of protruding the massage module 1110. The reference intensity is a massage intensity that can sufficiently relax the user's buttocks, and can be preset and stored in the memory 1430 by various objects. For example, the reference intensity can be set differently, such as an intensity that protrudes the massage module 1110 by about 4 cm to 8 cm.

[0355] As described above, the reference intensity can be preset, but it is not limited thereto. For example, the control unit 1400 may determine a customized reference intensity customized for the user as the reference intensity based on at least one of the user's biological information, massage device usage history, and user preference information and other various information.

[0356] After that, in a state where the massage module 1110 protrudes, the control unit 1400 can move the massage module 1110 back and forth to perform additional massage on the user's buttocks (operation 1C_2). At this time, the control unit 1400 can repeatedly provide the additional massage, which performs additional massage on the user's buttocks through repeated back-and-forth movement. The back-and-forth movement may refer to an operation of kneading and massaging the user's buttocks by the massage module 1110.

[0357] For example, the control unit 1400 moves the massage module 1110 upward by a preset first distance in the upward direction of the massage module 1110, and then moves it downward by a preset second distance in the downward direction of the massage module 1110, so as to move the massage module 1110 back and forth. The first distance and the second distance can be preset by various objects and stored in the memory 1430. The first distance and the second distance can be set to be different or the same as each other. The upward direction of the massage module 1110 may be a direction 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 may be a direction from the upper side of the massage module 1110 toward the lower side of the massage module 1110.

[0358] As described above, the control unit 1400 moves the massage module 1110 back and forth in the upward and downward directions of the massage module 1110, but is not limited thereto. For example, the control unit 1400 can move the massage module 1110 back and forth in the front and rear directions of the massage module 1110. At this time, the front direction of the massage module 1110 may be a direction 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 may be a direction from the front of the massage module 1110 toward the rear of the massage module 1110. The front of the massage module 1110 may be a part that is disposed adjacent to the user and contacts the user's body.

[0359] Specifically, in a state where the massage module 1110 protrudes forward in the front direction of the massage module 1110, the control unit 1400 can further protrude the massage module 1110 forward by a first distance in the front direction of the massage module 1110, and then retreat it backward by a second distance in the rear direction of the massage module 1110, so as to move the massage module 1110 back and forth.

[0360] When performing additional massage on the user's buttocks through the back-and-forth movement of the massage module 1110 as described above, the control unit 1400 can reduce the length of any one of the leg massage parts with a preset length, and at the same time, maximally inflate the pelvic airbag of the body massage part 1100 to firmly fix the user's pelvis. For example, the control unit 1400 can maximally inflate the pelvic airbag when moving the massage module 1110 back and forth, or before the back-and-forth movement.

[0361] Accordingly, even during the reciprocating movement of the massage module 1110, the control unit 1400 can accurately provide additional massage to the user's buttocks by firmly fixing the user's pelvis, where the additional massage refers to performing additional massage on the user's buttocks.

[0362] As described above, the control unit 1400 performs the piriformis stretching actions (Actions 1A, 1B, and 1C) through any one of the leg massage units, but is not limited thereto. For example, after performing the piriformis stretching actions (Actions 1A, 1B, and 1C) through any one of the leg massage units, the control unit 1400 can further perform the piriformis stretching actions on the other leg massage unit. At this time, the piriformis stretching actions on the other leg massage unit can be the same actions as Actions 1A, 1B, and 1C.

[0363] In addition, the control unit 1400 can sequentially and repeatedly perform the piriformis stretching actions on each of the above-mentioned leg massage units.

[0364] Accordingly, the control unit 1400 stretches the user's both legs and both buttocks evenly and repeatedly, thereby relaxing the user's legs and buttocks as a whole, and thus can fully stretch and relax the user's piriformis muscle.

[0365] In addition, when performing the piriformis stretching actions, the control unit 1400 can provide heated massage by increasing the temperature of the massage module 1110 while providing massage to the user's buttocks through the massage module 1110.

[0366] Accordingly, the control unit 1400 provides a warm feeling to the user's buttocks and stretches and relaxes the user's buttocks. Therefore, compared with the case where no warm feeling is provided, the user's buttocks are stretched and relaxed more, thereby preventing injuries caused by stretching and relaxation.

[0367] Figure 32 A diagram showing the body airbag and leg airbag included in the body massage unit for explaining an embodiment of the present invention.

[0368] The body massage unit 1000 may include a body airbag 1600 that massages (or presses) the user's body.

[0369] For example, the body airbag 1600 may include at least one airbag corresponding to the user's shoulder, back, pelvis, thigh, and perineum.

[0370] Specifically, the body airbag 1600 may include: a first body airbag 1610 disposed on one side of the body massage unit 1000 to massage one side of the user's body; a second body airbag 1630 disposed on the other side of the body massage unit 1000 to massage the other side of the user's body; and a third body airbag 1650 disposed between one side and the other side of the body massage unit 1000 to massage between one side and the other side of the user's body. The first body airbag 1610 may be an airbag corresponding to the first leg massage unit 2000a, and the second body airbag 1610 may be an airbag corresponding to the second leg massage unit 2000b.

[0371] The first body airbag 1610 may include at least one airbag among a first shoulder airbag 1611, a first back airbag 1613, a first pelvis airbag 1615, and a first thigh airbag 1617. The second body airbag 1630 may include at least one airbag among a second shoulder airbag 1631, a second back airbag 1633, a second pelvis airbag 1635, and a second thigh airbag 1637.

[0372] The first shoulder airbag 1611 is disposed in a region corresponding to one side of the user's shoulder in the entire region of one side of the body massage unit 1000 (e.g., the upper end region of one side of the body massage unit 1000), so as to massage one side of the user's shoulder. The second shoulder airbag 1631 is disposed in a region corresponding to the other side of the user's shoulder in the entire region of the other side of the body massage unit 1000 (e.g., the upper end region of the other side of the body massage unit 1000), so as to massage the other side of the user's shoulder. At this time, the first shoulder airbag 1611 and the second shoulder airbag 1631 may massage (or fix) the user's shoulder by pressing on both side surfaces (or both upper surfaces) of the user's shoulder.

[0373] The first back airbag 1613 is disposed in a region corresponding to one side of the user's back in the entire region of one side of the body massage unit 1000 (e.g., the region between the upper end and the lower end of one side of the body massage unit 1000), so as to massage one side of the user's back. The second back airbag 1633 is disposed in a region corresponding to the other side of the user's back in the entire region of the other side of the body massage unit 1000 (e.g., the region between the upper end and the lower end of the other side of the body massage unit 1000), so as to massage the other side of the user's back. At this time, the first back airbag 1613 and the second back airbag 1633 may massage the user's back by pressing on the back surface of the user's back, thereby pushing (or moving) the user's back in the forward direction of the body massage unit 1000.

[0374] The first pelvic airbag 1615 is disposed in the entire area on one side of the body massage unit 1000 corresponding to one side of the user's pelvis (e.g., the lower end area on one side of the body massage unit 1000), so that the one side of the user's pelvis can be massaged. The second pelvic airbag 1635 is disposed in the entire area on the other side of the body massage unit 1000 corresponding to the other side of the user's pelvis (e.g., the lower end area on the other side of the body massage unit 1000), so that the other side of the user's pelvis can be massaged. At this time, the first pelvic airbag 1615 and the second pelvic airbag 1635 can massage (or fix) the user's pelvis by pressing both side surfaces of the user's pelvis.

[0375] The first thigh airbag 1617 is disposed in the entire area on one side of the body massage unit 1000 corresponding to the thigh of one side of the user's leg (or the central area on one side in the lower end central area of the body massage unit 1000), so that the thigh of one side of the user's leg can be massaged. The second thigh airbag 1637 is disposed in the entire area on the other side of the body massage unit 1000 corresponding to the thigh of the other side of the user's leg (or the central area on the other side in the lower end central area of the body massage unit 1000), so that the thigh of the other side of the user's leg can be massaged. At this time, the first thigh airbag 1617 and the second thigh airbag 1637 can massage the thighs on one side and the other side of the user by pressing the back of the user's thighs, thereby pushing the user's thighs in the upward direction of the body massage unit 1000.

[0376] The third body airbag 1650 is disposed in the entire area between one side and the other side of the body massage unit 1000 corresponding to the perineum of the user (e.g., the front central area of the body massage unit 1000), so that the perineum of the user can be massaged. At this time, the perineum airbag as the third body airbag 1650 can press the perineum of the user, thereby pushing the user's body in the upward direction of the body massage unit 1000.

[0377] In addition, the leg massage unit 2000 may include a leg airbag 1700 for massaging the user's legs.

[0378] For example, the leg airbag 1700 may include: a first leg airbag 1710 corresponding to the first leg massage unit 2000a (or one side of the user's leg); and a second leg airbag 1730 corresponding to the second leg massage unit 2000b (or the other side of the user's leg).

[0379] Specifically, the first leg massage part 2000a may include a first leg airbag 1710 disposed in at least a partial area of the first leg massage part 2000a, and the second leg massage part 2000b may include a second leg airbag 1730 disposed in at least a partial area of the second leg massage part 2000b.

[0380] Each leg airbag (the first leg airbag 1710, the second leg airbag 1730) may include at least one airbag among a calf airbag corresponding to the calf of the user and a foot airbag corresponding to the foot of the user.

[0381] For example, the first leg airbag 1710 may include at least one airbag among a first calf airbag 1711 and a second foot airbag 1713, and the second leg airbag 1730 may include at least one airbag among a second calf airbag 1731 and a second foot airbag 1733.

[0382] The first calf airbag 1711 may be disposed in an area corresponding to the calf of one leg of the user (e.g., the upper end area of the first leg massage part 2000a) in the entire area of the first leg massage part 2000a, so as to massage the calf of the user.

[0383] For example, the first calf airbag 1711 may include at least one sub-calf airbag among a first sub-calf airbag 1711a and a second sub-calf airbag 1711b. The first sub-calf airbag 1711a is disposed in an area corresponding to the side part of the calf of one leg to massage (or press) the side part of the calf, and the second sub-calf airbag 1711b is disposed in an area corresponding to the rear part of the calf of one leg to massage the rear part of the calf. At this time, the first sub-calf airbag 1711a may press both side parts of the calf of one leg, so as to massage (or fix) the calf of the user.

[0384] The second calf airbag 1731 is applied to the second leg massage part 2000b in the same manner as the above first calf airbag 1711, so detailed description thereof is omitted.

[0385] The first foot airbag 1713 may be disposed in an area corresponding to the foot of one leg of the user (e.g., the lower end area of the first leg massage part 2000a) in the entire area of the second leg massage part 2000b, so as to massage the foot of the user.

[0386] For example, the first foot airbag 1713 may include at least one sub-foot airbag among a first sub-foot airbag 1713a and a second sub-foot airbag 1713b. The first sub-foot airbag 1713a is disposed in a region corresponding to the foot side (or instep) of one leg to massage (or apply pressure to) the foot side (or instep), and the second sub-foot airbag 1713b is disposed in a region corresponding to the back of the foot (or heel, Achilles tendon) of one leg to massage (or apply pressure to) the back of the foot (or heel, Achilles tendon). At this time, the first sub-foot airbag 1713a can apply pressure to both sides of the foot of one leg, thereby massaging (or fixing) the user's foot.

[0387] The second foot airbag 1733 is applied to the second leg massage unit 2000b in the same manner as the above-described first foot airbag 1713, and thus detailed description thereof is omitted.

[0388] Figure 33 Shown for illustrative purposes Figure 27 The flowchart of the iliopsoas stretching mode shown, Figure 34 Shown for illustrative purposes Figure 33 The diagram of each action shown.

[0389] The control unit 1400 can control the operation of the massage device 1000 through actions corresponding to the iliopsoas stretching mode, thereby providing the user with an iliopsoas stretching mode for stretching the iliopsoas of the user's leg. At this time, the iliopsoas stretching mode may include a leg stretching action for stretching the user's leg (or the iliopsoas of the leg).

[0390] For example, as in Action 2A, the control unit 1400 may tilt the massage device 1000 (Action S3310) before performing the leg stretching action.

[0391] Specifically, the control unit 1400 tilts the body massage unit 1100 backward (or while tilting) based on a preset body angle, and then tilts the leg massage unit 2000 in the upward direction of the massage device 1000 based on a preset leg angle, thereby adjusting the angle of the leg massage unit 2000.

[0392] The body angle and the leg angle can be preset by various objects and stored in the memory 1430. The body angle is any angle between the minimum body angle and the maximum body angle between the ground and the body massage unit 1100, and can be an angle greater than the minimum body angle and less than the maximum body angle. The minimum body angle can be the maximum angle at which the body massage unit 1100 tilts forward (tilted to the maximum) towards the front of the body massage unit 1100. The maximum body angle can be the maximum angle at which the body massage unit 1100 tilts backward towards the rear of the body massage unit 1100. The leg angle is any angle between the minimum leg angle and the maximum leg angle between the body massage unit 1100 and each leg massage unit, and can be an angle greater than the minimum leg angle and less than the maximum leg angle. The minimum leg angle can be the maximum angle at which each leg massage unit tilts downward towards the lower side of the massage device 1000. The maximum leg angle can be the maximum angle at which each leg massage unit tilts upward towards the upper side of the massage device 1000.

[0393] The control unit 1400 can perform a preliminary action including at least one of a relaxation massage providing action and a leg length measurement action in a state where the massage device 1000 is tilted.

[0394] For example, the control unit 1400 can provide a relaxation massage for relaxing the user's body (or while providing it), and measure the user's leg length.

[0395] The relaxation massage providing action and the leg length measurement action are the same as those described above, so detailed description is omitted. However, when providing the relaxation massage, the control unit 1400 can move the massage module 1110 to a position corresponding to the user's hip. The massage module moving action can apply the content described in Action 1B_2, so detailed description is omitted.

[0396] The control unit 1400 can perform a leg stretching action (Action S3330) through the leg length adjustment module 2500 and the leg angle adjustment module 1350 in a state where the massage device 1000 is tilted.

[0397] The leg stretching action may include a first leg stretching action and / or a second leg stretching action. The first leg stretching action can stretch the iliopsoas muscle of one side of the leg by stretching one side of the user's leg. The second leg stretching action can stretch the iliopsoas muscle of the other side of the leg by stretching the other side of the user's leg.

[0398] For example, the control unit 1400 can sequentially and repeatedly perform the first leg stretching action and the second leg stretching action based on a preset number of repetitions. At this time, the number of repetitions can be preset by various objects and stored in the memory 1430. Hereinafter, for convenience of explanation, it is assumed that the first leg stretching action and the second leg stretching action are not repeatedly performed.

[0399] First, as in Action 2B, the control unit 1400 may perform a first leg stretching action (Action S3331).

[0400] For example, as in Action 2B-1, the control unit 1400 may increase the length of the first leg massaging unit 2000a while adjusting or maintaining the length of the second leg massaging unit 2000b. At this time, the length of the first leg massaging unit 2000a may refer to the length from one end to the other end of the first leg massaging unit 2000a. The length of the second leg massaging unit 2000b may refer to the length from one end to the other end of the second leg massaging unit 2000b.

[0401] Specifically, the control unit 1400 may determine an adjustment length for adjusting the length of the first leg massaging unit 2000a based on the length of one leg of the user. The control unit 1400 may adjust the length of the first leg massaging unit 2000a based on the adjustment length. The first leg massaging unit 2000a length adjustment action will be described in detail below.

[0402] Hereinafter, for convenience of description, it is assumed that the length of the first leg massaging unit 2000a is adjusted while adjusting the length of the second leg massaging unit 2000b during the first leg stretching action.

[0403] As in Action 2B-2, the control unit 1400 may adjust the angle of the first leg massaging unit 2000a while maintaining the angle of the second leg massaging unit 2000b. At this time, the angle of the first leg massaging unit 2000a may refer to the angle between the first leg massaging unit 2000a and the body massaging unit 1100 (or the seat portion of the body massaging unit). The angle of the second leg massaging unit 2000b may refer to the angle between the second leg massaging unit 2000b and the body massaging unit 1100.

[0404] For example, the control unit 1400 may determine an adjustment angle for adjusting the angle of the first leg massaging unit 2000a based on the length of one leg of the user. The control unit 1400 may adjust the angle of the first leg massaging unit 2000a based on the adjustment angle. The first leg massaging unit 2000a angle adjustment action will be described in detail below.

[0405] After performing the first leg stretching action, the control unit 1400 may restore the position of the leg massaging unit 2000. The restored angle and length of the leg massaging unit 2000 may be the angle and length of the leg massaging unit 2000 before performing the first leg stretching action.

[0406] After that, as in Action 2C, the control unit 1400 may perform a second leg stretching action (Action S3333).

[0407] For example, as in operation 2C-1, the control unit 1400 may increase the length of the second leg massaging unit 2000b while adjusting or maintaining the length of the first leg massaging unit 2000a.

[0408] Specifically, the control unit 1400 may determine an adjustment length for adjusting the length of the second leg massaging unit 2000b based on the length of the other leg of the user. The control unit 1400 may adjust the length of the second leg massaging unit 2000b based on the adjustment length. The second leg massaging unit 2000b length adjustment operation may apply the first leg massaging unit 2000a length adjustment operation included in the first leg stretching operation described below.

[0409] Hereinafter, for convenience of explanation, it is assumed that the length of the second leg massaging unit 2000b is adjusted in a state where the length of the first leg massaging unit 2000a is adjusted during the second leg stretching operation.

[0410] As in operation 2C-2, the control unit 1400 may adjust the angle of the second leg massaging unit 2000b while maintaining the angle of the first leg massaging unit 2000a.

[0411] For example, the control unit 1400 may determine an adjustment angle for adjusting the angle of the second leg massaging unit 2000b based on the length of the other leg of the user. The control unit 1400 may adjust the angle of the second leg massaging unit 2000b based on the adjustment angle. The second leg massaging unit 2000b angle adjustment operation may apply the first leg massaging unit 2000a angle adjustment operation included in the first leg stretching operation described below.

[0412] After performing the second leg stretching operation, the control unit 1400 may restore the position of the leg massaging unit 2000.

[0413] As in operation 2D, after performing the leg stretching operation, the control unit 1400 may perform an operation (operation S3350) of providing a finishing massage for stretching the legs and hips of the user through the leg length adjustment module 2500, the leg angle adjustment module 1350, and the massage module 1110.

[0414] For example, in a state where the position of the leg massaging unit 2000 is restored, the control unit 1400 may tilt each leg massaging unit in the upward direction of the massage device 1000 while reducing the length of the leg massaging unit. As an example, the control unit 1400 may adjust the angle and length of each leg massaging unit according to the adjustment length and adjustment angle of the length of each leg. As another example, the control unit 1400 may adjust the angle of each leg massaging unit to the maximum leg angle and may adjust the length of each leg massaging unit to the minimum length.

[0415] The control unit 1400 can provide massage to the user's buttocks through the massage module 1110 while adjusting the angles and lengths of each leg massage unit. At this time, the massage provided to the buttocks can be a buttocks massage applicable to the piriformis muscle stretching mode, such as at least one of acupressure massage, kneading massage, tapping massage, and compound massage, etc.

[0416] After providing the massage, the control unit 1400 can end the iliopsoas muscle stretching mode.

[0417] The length adjustment actions of each leg massage unit included in the above first leg stretching action and second leg stretching action can be executed simultaneously, or at time intervals, or sequentially. Hereinafter, for convenience of explanation, it is assumed that the length adjustment actions of each leg massage unit are executed simultaneously.

[0418] Hereinafter, the first leg stretching action can be applied to the second leg stretching action. For convenience of explanation, only the first leg stretching action will be described. For example, the actions of the first leg massage unit 2000a included in the first leg stretching action can be applied to the actions of the second leg massage unit 2000b included in the second leg stretching action. The actions of the second leg massage unit 2000b included in the first leg stretching action can be applied to the actions of the first leg massage unit 2000a included in the second leg stretching action.

[0419] Figure 35 Shown for illustration Figure 33 A diagram showing the first leg stretching action shown.

[0420] The control unit 1400 can increase the length of the first leg massage unit 2000a while reducing the length of the second leg massage unit 2000b through the leg length adjustment module 2500 (action S3331a).

[0421] For example, the control unit 1400 can, in a state where the massage device 1000 is tilted, tilt the leg massage unit 2000 maximally upward with respect to the massage device 1000 based on the maximum leg angle.

[0422] The control unit 1400 can, in a state where the leg massage unit 2000 is tilted maximally, reduce the length of the second leg massage unit 2000b by a preset length while increasing the length of the first leg massage unit 2000a.

[0423] When reducing the length of the second leg massage unit 2000b, the control unit 1400 can move the second leg massage unit 2000b to the maximum extent in the upward direction of the second leg massage unit 2000b in a state where the second leg airbag 1730 is contracted, so as to reduce the length of the second leg massage unit 2000b to the shortest minimum length, but not limited thereto. For example, similar to the method of adjusting the length of the first leg massage unit 2000a described later, the control unit 1400 can reduce the length of the second leg massage unit 2000b based on the length of the other leg of the user.

[0424] When increasing the length of the first leg massage unit 2000a, the control unit 1400 can increase the length of the first leg massage unit 2000a based on the length of one leg of the user after (or while) inflating the first leg airbag 1710. The method of inflating the first leg airbag 1710 can be applied to the method of inflating the leg airbags (for example, the first sub-calf airbag and the second sub-calf airbag, the first sub-foot airbag and the second sub-foot airbag, etc.) in the action S3010 of the piriformis stretching mode.

[0425] For example, the control unit 1400 can determine the adjustment length for increasing the length of the first leg massage unit 2000a based on the length of one leg of the user. The control unit 1400 can increase the length of the leg massage unit 2000a by moving the first leg massage unit 2000a in the downward direction of the first leg massage unit 2000a based on the adjustment length. At this time, the control unit 1400 can move the first leg massage unit 2000a by the adjustment length, or move it to a position corresponding to the first adjustment length.

[0426] The above adjustment length determination method can be as follows. For example, the memory 1430 can store a leg length table including a plurality of leg lengths and adjustment lengths matching each leg length. The leg length table can be preset by various objects and stored in the memory 1430. The control unit 1400 can extract the adjustment length matching any one of the plurality of leg lengths in the leg length table based on the length of one leg of the user. At this time, any one of the leg lengths can be a length the same as or similar to the length of one leg of the user. The control unit 1400 can determine the extracted adjustment length as the adjustment length for adjusting the length of the first leg massage unit 2000a.

[0427] That is, the control unit 1400 can stretch one leg of the user by fixing one leg of the user to the first leg massage unit 2000a (or while fixing) by only inflating the first leg airbag 1710 and then adjusting the length of the first leg massage unit 2000a.

[0428] In addition, when increasing the length of the first leg massage unit 2000a, the control unit 1400 can massage the foot of one leg (or while massaging) by operating the first foot massage unit 2610 in a state where the second foot massage unit 2630 is stopped, thereby increasing the length of the first leg massage unit 2000a. At this time, the driving operation of the first foot massage unit 2610 can be linked with at least one of the inflation operation of the first leg airbag 1710 and the length increase operation of the first leg massage unit 2000a. The driving operation of the first foot massage unit 2610 can end when the length increase operation of the first leg massage unit 2000a is completed.

[0429] In other words, the control unit 1400 stretches one leg of the user by linking at least one of the driving operation of the first foot massage unit 2610, the inflation operation of the first leg airbag 1710, and the length increase operation of the first leg massage unit 2000a in a state where the second foot massage unit 2630 is stopped and the second leg airbag 1730 is contracted.

[0430] 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 (operation S3331b).

[0431] For example, the control unit 1400 can adjust the angle of the first leg massage unit 2000a by tilting the first leg massage unit 2000a in the downward direction of the massage device 1000 in a state where the length of the first leg massage unit 2000a is increased and the first leg airbag 1710 is inflated.

[0432] When adjusting the angle of the first leg massage unit 2000a, the control unit 1400 can adjust the angle of the first leg massage unit 2000a based on the length of one leg of the user.

[0433] For example, the control unit 1400 can determine an adjustment angle for adjusting the angle of the first leg massage unit 2000a based on the length of one leg of the user. Based on the adjustment angle, the control unit 1400 tilts the first leg massage unit 2000a in the downward direction of the massage device 1000, thereby adjusting the angle of the first leg massage unit 2000a. At this time, the control unit 1400 tilts the first leg massage unit 2000a by the adjustment angle or to a position corresponding to the adjustment angle.

[0434] The above-described method for determining the adjustment angle can be similar to the method for determining the adjustment length. For example, the memory 1430 can store a leg angle table including multiple leg lengths and the adjustment angles matching each leg length. The leg angle table can be preset by various objects and stored in the memory 1430. The control unit 1400 can extract the adjustment angle matching any one of the multiple leg lengths pre-stored in the memory 1430 based on the length of one leg of the user. At this time, any one of the leg lengths can be the leg length that is the same as or similar to the length of one leg of the user. The control unit 1400 can determine the extracted adjustment angle as the adjustment angle for adjusting the angle of the first leg massage unit 2000a.

[0435] That is, the control unit 1400 can stretch one leg of the user by adjusting the angle of the first leg massage unit 2000a in a state where the length of the first leg massage unit 2000a is increased and the first leg airbag 1710 is inflated.

[0436] 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 is not limited thereto.

[0437] For example, the control unit 1400 can execute by linking at least one of the angle adjustment action of the first leg massage unit 2000a, the tilting action of the body massage unit 1100, the inflation action of the body airbag 1600, and the hip massage providing action.

[0438] Regarding the tilting action of the body massage unit 1100, the control unit 1400 can adjust the angle of the first leg massage unit 2000a by tilting the body massage unit 1100 while maintaining the angle between the body massage unit 1100 and the second leg massage unit 2000b. For example, the control unit 1400 can tilt the body massage unit 1100 to the maximum extent backward based on the maximum body angle.

[0439] Regarding the inflation action of the body airbag 1600, the control unit 1400 can adjust the angle of the first leg massage unit 2000a after (or while) moving the user's body by inflating the body airbag 1600. At this time, the control unit 1400 can inflate the body airbag 1600 after (or while) increasing the length of the second leg massage unit 2000b.

[0440] As an example, the control unit 1400 can move the user's body upward (or while moving) the massage device 1000 by inflating at least one of the thigh airbags (the first thigh airbag 1617 and the second thigh airbag 1637) and the perineum airbag 1650, and then adjust the angle of the first leg massage unit 2000a. At least one of the thigh airbags (the first thigh airbag 1617 and the second thigh airbag 1637) and the perineum airbag 1650 can be inflated in a state where the length of the first leg massage unit 2000a is increasing or in a state where the length of the first leg massage unit 2000a has increased.

[0441] As another example, the control unit 1400 can move the user's body to any one of the side portions of the massage device 1000 by inflating at least one of the back airbags (the first back airbag 1613 and the second back airbag 1633) and the pelvic airbags (the first pelvic airbag 1615 and the second pelvic airbag 1635), and then (or while moving) adjust the angle of the first leg massage unit 2000a. At least one of the back airbags (the first back airbag 1613 and the second back airbag 1633) and the pelvic airbags (the first pelvic airbag 1615 and the second pelvic airbag 1635) can be inflated in a state where the length of the first leg massage unit 2000a is increasing or in a state where the length of the first leg massage unit 2000a has increased.

[0442] For example, at least one of the airbags may include at least one of the second back airbag 1633 and the second pelvic airbag 1635 corresponding to the second leg massage unit 2000b. In other words, the control unit 1400 can move the user's body to the side portion of the massage device 1000 corresponding to the first leg massage unit 2000a by inflating at least one of the second back airbag 1633 and the second pelvic airbag 1635.

[0443] As still another example, the control unit 1400 can move the user's body (or while moving) by inflating at least one of the back airbags (the first back airbag 1613 and the second back airbag 1633) and the pelvic airbags (the first pelvic airbag 1615 and the second pelvic airbag 1635) (or while inflating), and inflating at least one of the thigh airbags (the first thigh airbag 1617 and the second thigh airbag 1637) and the perineum airbag 1650, and then adjust the angle of the second leg massage unit 2000b.

[0444] Regarding the action of providing hip massage, the control unit 1400 can provide hip massage to the user's hip through the massage module 1110 before, after, or while adjusting the angle of the first leg massage unit 2000a.

[0445] Specifically, the control unit 1400 presses the user's buttocks by protruding the massage module 1110 forward of the massage module 1110, thereby providing buttocks massage to the user.
