Description

[Technical field]

[0001] The present invention relates to a massage device that provides a massage mode for stretching a user's legs, and more particularly to a massage device that stretches a user's legs via an independently movable leg massage unit. [Background technology]

[0002] Massage is a medically assisted therapy that regulates the subject's physical condition, aids blood circulation, and relieves fatigue by applying various forms of mechanical stimulation to parts of the subject's body, such as kneading, pushing, pulling, tapping, or moving the body.

[0003] The increase in the demand for massage has led to an increase in the demand for massage devices that provide an artificial massage function due to economic and time reasons. As a result, various massage devices that are time- and cost-efficient have been released as the demand for relieving fatigue or stress by relieving stiff muscles through massage increases.

[0004] Recently, people's interest in health has increased, and massage devices have changed from simply providing massage functions to electronic devices providing various additional and / or medical functions, which has led to continuous research into how to efficiently control massage devices.

[0005] In particular, since the part of the body that a user desires to receive a massage and the stimulation that the user desires may differ from one another, research activities into devices and methods for providing massage in an optimized form for each user are increasing.

[0006] As one such example, Korean Patent Publication No. 10-2020-0100561 discloses an example of a massage device that is divided into a first leg massage section that receives the right leg and a second leg massage section that receives the left leg, and the first leg massage section and the second leg massage section are driven independently.

[0007] Meanwhile, in the case of the independently driven leg massage units, there is a problem that a part of the user's body may be pinched between the leg massage units due to the independently driven leg massage units, which may cause a safety accident.

[0008] Therefore, there is a need for research into a massage device that includes an independently driven leg massage unit and is capable of preventing safety accidents. Summary of the Invention [Problem to be solved by the invention]

[0045] The leg massage unit 1300 includes an accommodation space for accommodating the user's legs and can provide a leg massage to the user by massaging at least a portion of the user's legs. For example, the leg massage unit 1300 can include a calf massage unit for massaging the user's calves and / or a foot massage unit for massaging the user's feet.

[0046] The length of the leg massage unit 1300 can be adjusted according to the physical characteristics of the user. For example, when a tall user uses the massage device 1000, the length of the leg massage unit 1300 needs to be long since the length of the calf is long. Also, when a short user uses the massage device 1000, the length of the calf is short, so the leg massage unit 1300 needs to be short. As a result, the leg massage unit 1300 can provide a leg massage adjusted according to the height of the user. According to an embodiment of the present invention, the user can control the massage device 1000 using a massage device control device (CD). The massage device control device (CD) may be connected to the massage device 1000 via wired communication and / or wireless communication.

[0050] A rack gear 1131a may be provided on at least a portion of the upper frame 1131. The rack gear 1131a is a member for guiding the upward and downward movement of the massage module 1110, and may include a plurality of valleys and a plurality of peaks.

[0051] According to an embodiment of the present invention, the rack gears 1131a may be provided on both sides of the upper frame 1131 in a form facing each other, and the massage module 1110 may move along the rack gears 1131a.

[0052] In Fig. 2, the rack gear 1131a is formed in the up-down direction, but is not limited thereto. The rack gear 1131a may include a front-rear rack gear and an up-down rack gear. In the present disclosure, the front-rear direction means a direction from the massage module 1110 to the user or a direction from the user to the massage module 1110, and may mean the X-axis direction based on Fig. 2.

[0053] The massage module 1110 may include a gear that meshes with the rack gear 1131a. More specifically, the massage module 1110 may include gears that mesh with the front-rear rack gear and the up-down rack gear. 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.

[0054] The further forward the massage module 1110 moves, the stronger the massage may be, and the further back the massage module 1110 moves, the weaker the massage may be.

[0055] The rack gear 1131a may be made of a metal material or a plastic material, for example, iron, steel, alloy, reinforced plastic, melamine resin, phenolic resin, etc., but is not limited thereto.

[0056] The upper frame 1131 may be implemented in various shapes, for example, the upper frame 1131 may be classified into an S frame, an L frame, an S&L frame, and a double S&L frame according to the shape, but is not limited thereto.

[0057] The S frame refers to a frame in which at least a portion of the upper frame 1131 includes an "S"-shaped bent shape. The L frame refers to a frame in which at least a portion of the upper frame 1131 includes an "L"-shaped bent shape. The S&L frame refers to a frame that includes both an "S"-shaped bent shape and an "L"-shaped bent shape. The double S&L frame refers to a frame that includes an "L"-shaped bent shape and two parts of an "S"-shaped bent shape.

[0058] The base frame 1132 refers to a portion that supports the upper frame 1131 and comes into contact with the ground. The base frame 1132 can include a base upper frame 1132a and a base lower frame 1132b.

[0059] The base upper frame 1132a may support the upper frame 1131, and the base lower frame 1132b may contact the ground. Also, the base upper frame 1132a may be positioned to contact the base lower frame 1132b.

[0060] According to an embodiment of the present invention, the base upper frame 1132a can move along the base lower frame 1132b. For example, the base upper frame 1132a can slide forward or backward along the base lower frame 1132b. In this case, the upper frame 1131 is connected to the base upper frame 1132a and can move according to the movement of the base upper frame 1132a.

[0061] For example, when the base upper frame 1132a moves forward, the upper frame 1131 can move forward together with it, and when the base upper frame 1132a moves backward, the upper frame 1131 can move backward together with it. This allows the body massage part 1100 to slide.

[0062] To allow the base upper frame 1132a to move, a moving wheel may be provided on the lower part of the base upper frame 1132a. Also, a guide member capable of guiding the moving wheel may be provided on the upper part of the base lower frame 1132b. The moving wheel provided on the base upper frame 1132a may move along the guide member provided on the base lower frame 1132b, thereby allowing the base upper frame 1132a to move forward or backward.

[0063] According to other embodiments of the present invention, the massage device 1000 may not provide a sliding function, in which case the base frame 1132 may not be separated into upper and lower frames.

The center rotation member cover 1532c may be welded to the first center rotation member 1532a and the second center rotation member 1532b or may be connected via a separate fastening member. However, the first center rotation member 1532a, the second center rotation member 1532b, and the center rotation member cover 1532c may be integrally provided. In other words, the first center rotation member 1532a, the second center rotation member 1532b, and the center rotation member cover 1532c may be integrally provided by bending and cutting one member multiple times.

[0148] 13B, the center rotating member cover 1532c may be connected to the outside of the first center rotating member 1532a and the second center rotating member 1532b. The center rotating member cover 1532c may be welded to the first center rotating member 1532a and the second center rotating member 1532b or connected via a separate fastening member. In this case, the center rotating member cover 1532c may be provided to entirely cover the upper part of the first center rotating member 1532a and the second center rotating member 1532b.

[0149] In addition, the center rotation member cover 1532c may be connected to the first center rotation member 1532a and the second center rotation member 1532b by a hardware configuration such as sliding or hooking the center rotation member cover 1532c to the first center rotation member 1532a and the second center rotation member 1532b. As long as the center rotation member cover 1532c is configured to cover at least a part of the upper portion of the first center rotation member 1532a and the second center rotation member 1532b, the configuration for connecting the center rotation member cover 1532c may be replaced by various methods commonly used in the technical field to which the present invention pertains.

[0150] The center support bracket 1530 may correspond to one component of a safety sensor module 1500, which will be described later. A detailed description of the configuration of the center support bracket 1530 will be given later.

[0151] The side support brackets 1550 may be provided on both sides of the leg connection frame 1131b. The side support brackets 1550 may include a first side support bracket 1550a provided on the right end of the leg connection frame 1131b and a second side support bracket 1550b provided on the left end. The first side support bracket 1550a and the second side support bracket 1550b may be provided in corresponding shapes.

[0152] The first side support bracket 1550a can rotatably fix the first side bushing 1312. The second side support bracket 1550b can rotatably fix the second side bushing 1322. Bearings may be provided between the side support bracket 1550 and the side bushings 1312 and 1322 to ensure smooth rotation.

[0153] The side support bracket 1550 can include, for example, a side fixed member 1551 and a side rotating member 1552 .

[0154] The side fixing member 1551 may be welded to the leg connecting frame 1131b or may be connected by a separate fastening member. One side of the side rotating member 1552 may be rotatably connected to the side fixing member 1551. When the side rotating member 1552 rotates and an end of the side rotating member 1552 comes into contact with the side fixing member 1551, the side rotating member 1552 may be fastened by a fastening member.

[0155] 14(A) and (B) are diagrams showing the process of fastening a center bushing to a center support bracket, and FIG. 14(C) and (D) are diagrams showing the process of fastening a side bushing to a side support bracket.

[0156] The process of fastening the first center bushing 1311 to the center support bracket 1530 will be described with reference to FIGS.

[0157] The first center fixing member 1531a may be coupled to the leg connecting frame 1131b. For example, the first center fixing member 1531a may be welded to the leg connecting frame 1131b in a state where the leg connecting frame 1131b is inserted into a leg connecting frame insertion groove 1531d-1 formed on one side of the first center fixing member 1531a, or may be coupled to the leg connecting frame 1131b via a separate fastening member.

[0158] When the first center fixing member 1531a is coupled to the leg connecting 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 the center rotating shaft 1532a-1, and can rotate upward based on the center rotating shaft 1532a-1. Here, the center rotating shaft 1532a-1 can mean a separate rotating shaft that rotatably connects the first center fixing member 1531a and the first center rotating member 1532a. However, the center rotating shaft 1532a-1 can be integrally provided on either the first center fixing member 1531a or the first center rotating member 1532a.

[0159] The first center bushing 1311 can be seated in the center bushing receiving groove 1531d-5 of the first center fixing member 1531a.

[0160] When the first center bushing 1311 is seated, the first center rotation member 1532a can rotate downward. At this time, at least a portion of the upper outer circumferential surface of the first center bushing 1311 can be received in the center bushing fixing groove 1532d of the first center rotation member 1532a. The center bushing receiving groove 1531d-5 and the center bushing fixing groove 1532d can rotatably support the first center bushing 1311.

[0161] When the first center rotating member 1532a rotates downward and an end portion thereof comes into contact with the fixing piece 1531d-4 of the first center fixing member, the first center rotating member 1532a can be fastened to the fixing piece 1531d-4 by the fastening member.

[0162] The process of fastening the second center bushing 1321 to the center support bracket 1530 is the same as the process of fastening the first center bushing 1311 to the center support bracket 1530 described above.

[0163] The process of fastening the first side bushing 1312 to the first side support bracket 1550a will be described with reference to FIGS.

[0164] The side fixing member 1551 may be coupled to the leg connecting frame 1131b. For example, the side fixing member 1551 may be welded to the leg connecting frame 1131b or may be coupled to the leg connecting frame 1131b via a separate fastening member.

[0165] When the side fixing member 1551 is coupled to the leg connecting frame 1131b, the side rotating member 1552 can rotate upward. For example, the side rotating member 1552 can be rotatably hinged to the side fixing member 1551 via the side rotating shaft 1552b, and can rotate upward based on the side rotating shaft 1552b. Here, the side rotating shaft 1552b can mean a separate rotating shaft that rotatably connects the side fixing member 1551 and the side rotating member 1552. However, the side rotating shaft 1552b can be integrally provided on either the side fixing member 1551 or the side rotating member 1552.

[0166] The first side bushing 1312 can be seated in a side bushing receiving groove 1551 a of the side fixing member 1551 .

[0167] When the first side bushing 1312 is seated, the side rotation member 1552 can rotate downward. At this time, at least a portion of the upper outer circumferential surface of the first side bushing 1312 can be received in the side bushing fixing groove 1552a of the side rotation member 1552. The side bushing receiving groove 1551a and the side bushing fixing groove 1552a can rotatably support the first side bushing 1312.

[0168] When the side rotation member 1552 rotates downward and the end portion comes into contact with the side fixing member 1551, the side rotation member 1552 can be fastened to the side fixing member 1551 by the fastening member.

[0169] 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.

[0170] As described above, since the center bushing and the side bushing can be fixed by fastening them to the center support bracket 1530 and the side support bracket 1550, the leg massage unit 1300 can be easily connected to the body massage unit 1100.

[0171] FIG. 15 is an enlarged view of portion D in FIG. 7, FIG. 16 is a view showing a disassembled state of a safety sensor module according to one embodiment of the present invention, and FIG. 17 is a view showing another embodiment of a safety sensor module according to one embodiment of the present invention.

[0172] 15 and 16, a massage device 1000 according to one embodiment of the present invention can include a safety sensor module 1500. As shown in FIG.

[0173] The safety sensor module 1500 may be provided in the leg connecting frame 1131b. For example, the safety sensor module 1500 may be provided in a portion of the leg connecting frame 1131b corresponding to the space between the first leg massage part 1310 and the second leg massage part 1330.

[0174] When an external force is applied, the safety sensor module 1500 can control the driving of at least one of the first leg massage unit 1310 and the second leg massage unit 1330. For example, when an external force is applied, the safety sensor module 1500 can stop the rotation operation of at least one of the first leg massage unit 1310 and the second leg massage unit 1330. In addition, when an external force is applied, the safety sensor module 1500 can rotate the first leg massage unit 1310 and the second leg massage unit 1330 by a predetermined angle in a direction opposite to a direction in which at least one of the first leg massage unit 1310 and the second leg massage unit 1330 rotates.

[0175] The safety sensor module 1500 may include an alarm unit (not shown) that issues a warning signal to a user when an external force is applied. The alarm unit may include, for example, at least one of a light-emitting lamp, an audio device, and a vibration element. The light-emitting lamp may emit light to issue a warning signal to a user. The audio device may correspond to the above-mentioned audio output module 1120 or may refer to a separate audio device. The audio device may issue a warning signal to a user through a warning sound. The vibration element may be a vibration panel, a vibration actuator, or the like. 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, and may issue a warning signal by applying vibration to a user. In this case, the light-emitting lamp and / or the vibration element may be disposed in the leg massage unit 1300. For example, the light-emitting lamp may be disposed in various positions on the exterior (or outside) of the leg massage unit 1300. The vibration elements may be arranged in the region of the entire region of the leg massage portion 1300 that comes into contact with the user's body (eg, the region corresponding to the sole of the foot and the region corresponding to the calf).

[0176] Therefore, the safety sensor module 1500 can prevent a safety accident that may occur when the user's body is caught between the leg massage parts 1300. In addition, the safety sensor module 1500 can prevent damage / failure of the device that may occur when an object enters between the leg massage parts 1300.

[0177] The safety sensor module 1500 can include a sensor bracket 1510 , a sensor 1520 , a center support bracket 1530 , and a pressure plate 1540 .

[0178] A sensor bracket 1510 may be provided to support a sensor 1520. The sensor bracket 1510 may be coupled to the leg connection frame 1131b. For example, the sensor bracket 1510 may be coupled to the leg connection frame 1131b by welding or via a separate fastening member. A method for 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 invention pertains.

[0179] TIFF2025511547000002.tif47151

[0180] The sensor 1520 can be coupled to the sensor bracket 1510. For example, the sensor 1520 can be coupled to the bent part 1512 of the sensor bracket 1510. At this time, at least a part of the sensor 1520 may be provided to pass through the sensor coupling hole 1512a. Thus, at least a part of the sensor 1520 can protrude forward of the bent part 1512.

[0181] The sensor 1520 can recognize the contact of the pressure plate 1540. For example, when an external force is applied to the pressure plate 1540 and the pressure plate 1540 rotates, the pressure plate 1540 can come into contact with the sensor 1520. When the pressure plate 1540 comes into contact, the sensor 1520 can transmit corresponding information to the control unit 1400. When the control unit 1400 receives information that the pressure plate 1540 has come into contact from the sensor 1520, it can control the operation of at least one of the first leg massage unit 1310 and the second leg massage unit 1330 as described above. In addition, the control unit 1400 can drive an alarm unit to send a warning signal to the user.

[0182] The sensor 1520 may be provided as a sensor that utilizes a measuring means such as pressure, potential, optics, etc. As an example, the sensor 1520 may include a sensor housing 1521, a contact portion 1522 provided in the sensor housing 1521 and sensing contact with the pressure plate 1540, a fastening portion 1523 for fastening to the sensor bracket 1510, and an electrode terminal 1524 for electrical connection with an external device.

[0183] When pressure is applied by the pressure plate 1540, the contact part 1522 may slide toward the inside of the sensor housing 1521. For this reason, a separate elastic member may be provided inside the sensor housing 1521 to apply an elastic force to the contact part 1522. When the contact part 1522 receives pressure and slides toward the inside of the sensor housing 1521, the sensor 1520 may transmit a signal to the control unit 1400, and the control unit 1400 may control the operation of at least one of the first leg massage part 1310 and the second leg massage part 1330 as described above, or may transmit a warning signal to the user via the alarm unit.

[0184] The fastening portion 1523 may be provided for coupling to the sensor bracket 1510. The fastening portion 1523 may be made of an elastic material and may be inserted into the sensor coupling hole 1512a formed in the sensor bracket 1510 when the sensor 1520 is coupled. The fastening portion 1523 may include an inclined surface in order to easily insert into the sensor coupling hole 1512a. The inclined surface may be provided such that the distance from the sensor housing 1521 increases from the rear to the front of the sensor 1520 when one end of the inclined surface is fixed to the sensor housing 1521. In addition, the other end of the inclined surface may be provided with a flat surface for easy contact with the sensor coupling hole 1521a. The flat surface may contact the inner surface of the sensor coupling hole 1521a. The fastening portion 1523 may be bent toward the sensor housing 1521 when held by a user. Thus, when the sensor 1520 needs to be separated, a user can grasp the fastening portion 1523 to separate the sensor 1520 from the sensor bracket 1510.

[0185] Meanwhile, the sensor 1520 may be replaced with various sensors commonly used in the technical field to which the present invention pertains, so long as the sensor 1520 can recognize the rotation or contact of the pressure plate 1540. For example, the sensor 1520 may be at least one of a pressure sensor, an infrared sensor, an LED sensor, a touch sensor, and an electrode sensor.

[0186] The center support bracket 1530 may be disposed on both sides of the sensor bracket 1510. The center support bracket 1530 may be manufactured as a separate member from the sensor bracket 1510, or may be manufactured integrally with the sensor bracket 1510. Alternatively, the center support bracket 1530 and the sensor bracket 1510 may be manufactured as separate members, and then the center support bracket 1530 and the sensor bracket 1510 may be joined by a method such as welding. The method of joining the center support bracket 1530 and the sensor bracket 1510 may be replaced by various methods commonly used in the technical field to which the present invention belongs. A pressure plate 1540 may be rotatably connected to the center support bracket 1530. The sensor bracket 1510 may include a center fixing member 1531 and a center rotating member 1532.

[0187] The center fixing member 1531 may include, for example, a base part 1531c and side parts 1531d protruding upward from both sides of the base part 1531c. The base part 1531c and the side parts 1531d may be formed by bending a single member. However, the base part 1531c and the side parts 1531d may be manufactured as separate members and then combined.

[0188] The base part 1531c may form a bottom surface of the center fixing member 1531. At least one stopper 1531e may be provided on the base part 1531c. The stopper 1531e may limit an angle at which the pressure plate 1540 rotates in a direction away from the sensor 1520. The stopper 1531e may penetrate the base part 1531c and have an end protruding below the base part 1531c. When a single stopper 1531e is provided, the stopper 1531e may be disposed in a central region of the base part 1531c, and when a plurality of stoppers are provided, the stopper 1531e may be disposed in at least one of the central region and both side regions of the base part 1531c.

[0189] The position and structure of the stopper 1531e can be changed in various ways as long as the rotation angle of the pressure plate 1540 can be limited. For example, the stopper 1531e can be attached to the bottom surface of the base part 1531c so that the entire stopper 1531e protrudes below the base part 1531c. The stopper 1531e can also be manufactured integrally with the base part 1531c. The stopper 1531e can also be provided on the pressure plate 1540.

[0190] The side part 1531d may include a leg connection frame insertion groove 1531d-1. The leg connection frame 1131b may be inserted and coupled into the leg connection frame insertion groove 1531d-1. The leg connection frame insertion groove 1531d-1 may be formed by cutting out one end of the side part 1531d facing the leg connection frame 1131b. The leg connection frame insertion groove 1531d-1 may be formed in a shape in which an inner surface is fitted to an 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, a portion where the side part 1531d and the leg connection frame 1131b come into contact with each other may be welded. However, a method of coupling the side part 1531d and the leg connection frame 1131b may be replaced with a method commonly used in the technical field to which the present invention pertains.

[0191] The side part 1531d may include a center rotation member insertion hole 1531d-2. The center rotation member 1532 may be rotatably hinged to the center rotation member insertion hole 1531d-2. The center rotation member insertion hole 1531d-2 may be provided at various positions of the side part 1531d to allow the center rotation member 1532 to rotate on the top of the side part 1531d.

[0192] The side part 1531d may include a pressure plate insertion hole 1531d-3. One side of the pressure plate 1540 may be rotatably hinged to the pressure plate insertion hole 1531d-3. The pressure plate insertion hole 1531d-3 may be provided at various positions of the side part 1531d so that the other side of the pressure plate 1540 may rotate upward (see FIG. 16) or downward (see FIG. 17) and come into contact with the sensor 1520 when rotated beyond a preset angle. For example, the pressure plate insertion hole 1531d-3 may be provided at the front lower side (see FIG. 16) or the front upper side (see FIG. 17) of the side part 1531d.

[0193] One of the side parts 1531d protruding from both sides of the base part 1531c may have a fixing piece 1531d-4 bent toward the other side part 1531d. However, the fixing piece 1531d-4 may be made of a separate member and coupled to both side parts 1531d. When the center rotation member 1532 rotates and an end portion thereof comes into contact with the fixing piece 1531d-4, the end portion of the center rotation member 1532 and the fixing piece 1531d-4 may be fastened by a fastening member.

[0194] The side part 1531d may include a center bushing receiving groove 1531d-5. The center bushings 1311 and 1321 may be rotatably seated in the center bushing receiving groove 1531d-5. The center bushing receiving groove 1531d-5 may be formed by, for example, cutting out an upper end portion of the side part 1531d.

[0195] The center rotating member 1532 may be rotatably hinged to the side part 1531d. The center rotating member 1532 may include a center bushing fixing groove 1532d. When the center rotating member 1532 rotates to be engaged with the fixing piece 1531d-4 of the side part 1531d, the center bushing fixing groove 1532d can rotatably support the center bushings 1311 and 1321 together with the center bushing receiving groove 1531d-5.

[0196] The pressure plate 1540 may be hinged to the center support bracket 1530 so as to be rotatable. The pressure plate 1540 may include an elastic member 1541. The elastic member 1541 may apply an elastic force to the pressure plate 1540 so that a free end of the pressure plate 1540 rotates in a direction away from the sensor 1520. The elastic member 1541 may be formed of various members capable of applying an elastic force to the pressure plate 1540. As an example, the elastic member 1541 may be formed of a torsion spring. When the elastic member 1541 is formed of a torsion spring, both side ends of the torsion spring may contact at least one of the pressure plate 1540 and the center support bracket 1530 when the pressure plate 1540 rotates.

[0197] The elastic member 1541 can prevent the pressure plate 1540 from rotating simply due to the user's body or other objects coming into contact with the pressure plate 1540 in a situation where the user's body or other objects are not sandwiched between the leg massage units 1300 or between the leg massage unit 1300 and the body massage unit 1100.

[0198] The pressure plate 1540 can rotate and come into contact with the sensor 1520. For example, if an external force greater than or equal to the elastic force of the elastic member 1541 is applied to the pressure plate 1540, the pressure plate 1540 can rotate and come into contact with the sensor 1520.

[0199] 18A and 18B are diagrams illustrating a process in which the safety sensor module according to one embodiment of the present invention is driven.

[0200] 18A, one end of the pressure plate 1540 may be disposed to be separated from the sensor 1520 by the elastic force of the elastic member 1541, and the other end may contact the stopper 1531e. Since the elastic force is continuously acting on the pressure plate 1540, one end of the pressure plate 1540 may not contact the sensor 1520 unless a predetermined external force is applied for a predetermined time.

[0201] 18(B), when at least one of the leg massage unit 1300 and the body massage unit 1100 rotates while the user's body is sandwiched between the leg massage unit 1300 and / or between the leg massage unit 1300 and the body massage unit 1100, an external force (F) greater than the elastic force of the elastic member 1541 may be applied to the pressure plate 1540. Also, unless the sandwiched state is released, the external force (F) continues to act on the pressure plate 1540. In this case, the pressure plate 1540 rotates and one end of the pressure plate 1540 may come into contact with the sensor 1520. When the pressure plate 1540 comes into contact with the sensor 1520, the sensor 1520 may transmit corresponding information to the control unit 1400. When the control unit 1400 receives information from the sensor 1520 that the pressure plate 1540 has come into contact with the massager, the control unit 1400 can control the operation of at least one of the first leg massage unit 1310, the second leg massage unit 1330, and the body massage unit 1100, or can activate an alarm unit. This can prevent a safety accident that may occur when the user's body is caught between the leg massage units 1300 and / or between the leg massage unit 1300 and the body massage unit 1100.

[0202] In addition, it is possible to prevent equipment failure and damage that may occur when an object other than the user's body is caught between the leg massage unit 1300 or between the leg massage unit 1300 and the body massage unit 1100.

[0203] In the following, for convenience of explanation, the leg massage unit 1300 will be changed to a leg massage unit 2000, the first leg massage unit 1310 to a first leg massage unit 2000a, and the second leg massage unit 1330 to a second leg massage unit 2000b.

[0204] Fig. 19 is a schematic diagram of a leg length adjusting module of the leg massage unit 2000 according to an embodiment of the present invention, and Fig. 20 is a diagram for explaining the length adjusting principle of the leg massage unit 2000 according to an embodiment of the present invention. Fig. 21 is an enlarged view of part B in Fig. 19, and Fig. 22 is an enlarged view of part C in Fig. 19.

[0205] 19, the massage device 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 under the control of the control unit 1400.

[0206] The leg length adjustment module 2500 may include a first leg length adjustment module 2500a and a second leg length adjustment module 2500b.

[0207] The first leg length adjustment module 2500a may be included in the first leg massage unit 2000a. For example, the first leg length adjustment module 2500a may be disposed behind the first leg massage unit 2000a. Specifically, the first leg length adjustment module 2500a may be disposed between the rear of the first leg massage unit 2000a and the front of the first leg angle adjustment module 1350a.

[0208] The first leg length adjusting module 2500a can adjust the length of the first leg massage part 2000a by moving the position of the first leg massage part 2000a. At this time, the first leg length adjusting module 2500a can adjust the length of the first leg massage part 2000a based on the length of one leg of the user.

[0209] For example, the first leg length adjusting 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 direction of the upper side (or upward direction) and the lower side (or downward direction) of the first leg massage unit 2000a. In this case, 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 to 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 to the lower side of the first leg massage unit 2000a.

[0210] As another example, the first leg length adjusting module 2500a can adjust the length of the first leg massage unit 2000a by adjusting (or adjusting) the distance between the first upper and first lower leg massage units 2000aa, 2000ab by moving at least one of the first upper leg massage unit 2000aa and the first lower leg massage unit 2000ab of the first leg massage unit 2000a in at least one of the upper and lower directions of the first leg massage unit 2000a. In this case, the first upper leg massage unit 2000aa can massage the upper part of one leg of the user (e.g., the calf). For example, the first upper leg massage unit 2000aa can include a massage module that massages the upper part of the leg, such as an air cell and a roller, in at least a part of the entire area of ​​the first upper leg massage unit 2000aa. The second lower leg massage unit 2000ab can massage the lower part of the other leg of the user (e.g., the foot). For example, the second lower leg massage unit 2000ab may include massage modules, such as air cells and rollers, for massaging the lower parts of the legs in at least a portion of the entire area of ​​the second lower leg massage unit 2000ab.

[0211] The second leg length adjustment module 2500b may be included in the second leg massage unit 2000b. For example, the second leg length adjustment module 2500b may be disposed behind the second leg massage unit 2000b. Specifically, the second leg length adjustment module 2500b may be disposed between the rear of the second leg massage unit 2000b and the front of the second leg angle adjustment module 1350b.

[0212] The second leg length adjusting 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 adjusting module 2500b can adjust the length of the second leg massage part 2000b based on the length of the other leg of the user.

[0213] For example, the second leg length adjusting module 2500b may adjust the length of the second leg massage unit 2000b by moving the second leg massage unit 2000b in at least one direction of the upper side (or upward direction) and the lower side (or downward direction) of the second leg massage unit 2000b. In this case, the upper side direction of the second leg massage unit 2000b may be a direction from the lower side of the second leg massage unit 2000b to the upper side of the second leg massage unit 2000b, and the lower side direction of the second leg massage unit 2000b may be a direction from the upper side of the second leg massage unit 2000b to the lower side of the second leg massage unit 2000b.

[0214] As another example, the second leg length adjusting module 2500b may adjust (or adjust) the distance between the second upper and second lower leg massage units 2000ba, 2000bb by moving at least one of the second upper leg massage unit 2000ba and the second lower leg massage unit 2000bb of the second leg massage unit 2000b in at least one of the upward and downward directions of the second leg massage unit 2000b, thereby adjusting the length of the second leg massage unit 2000b. In this case, the second upper leg massage unit 2000ba may have the same configuration as the first upper leg massage unit 2000aa, and the second lower leg massage unit 2000bb may have the same configuration as the first lower leg massage unit 2000ab.

[0215] In other words, each leg massage part 2000a, 2000b can adjust the length of each leg massage part 2000a, 2000b based on each leg length via the adjustment module of each leg massage part.

[0216] Specifically, referring to Figures 19 and 20, the adjustment modules 2500a, 2500b may include lead screws 2510a, 2510b that adjust the distance between the upper leg massage units 2000aa, 2000ba and the lower leg massage units 2000ab, 2000bb, and leg length adjustment actuators 2520a, 2520b that provide power to the lead screws 2510a, 2510b.

[0217] According to a preferred embodiment, the lead screws 2510a, 2510b may be spirally formed along their outer surfaces, and the leg frame 2210 may include a fixing member through which the lead screws 2510a, 2510b penetrate, with the inner surface formed to correspond to the lead screws 2510a, 2510b. The leg frame 2210 may be provided in the upper leg massage parts 2000aa, 2000ba, and the lead screws 2510a, 2510b and the leg length adjustment actuators 2520a, 2520b may be provided in the lower leg massage parts 2000ab, 2000bb.

[0218] The lead screws 2510a, 2510b can be rotated by the leg length adjustment actuators 2520a, 2520b, and the lead screws 2510a, 2510b can move up and down while passing through the fixed member in a screw manner by rotating. As a result, the lower leg massage parts 2000ab, 2000bb can be moved closer to or farther away from the upper leg massage parts 2000aa, 2000ba by the rotation of the lead screws 2510a, 2510b, and the distance between the upper leg massage parts 2000aa, 2000ba and the lower leg massage parts 2000ab, 2000bb can be adjusted, and ultimately, the length of the first and second leg massage parts 2000a, 2000b can be adjusted.

[0219] 21, guide rails 2211a and 2211b may be formed on the inner sides of the leg frames 2210a and 2210b. In addition, the first and second leg massage units 2000a and 2000b may include guide rollers 2540a and 2540b that move along the guide rails 2211a and 2211b and guide bars 2530a and 2530b that support the guide rollers 2540a and 2540b. At this time, one end of the guide bars 2530a and 2530b may be connected to the lower leg massage units 2000ab and 2000bb. Therefore, as the lead screws 2510a and 2510b rotate, the guide bars 2530a and 2530b and the guide rollers 2540a and 2540b may move in the direction of the lower leg massage units 2000ab and 2000bb.

[0220] Meanwhile, the guide rollers 2540a and 2540b can move along the guide rails 2211a and 2211b. As a result, the guide rollers 2540a and 2540b can guide the lower leg massage parts 2000ab and 2000bb to move in an appropriate direction. Therefore, the leg massage parts 2000a and 2000b on both sides do not shake while the lower leg massage parts 2000ab and 2000bb move.

[0221] Meanwhile, the guide rails 2211a, 2211b may be formed on a part of the inside of the leg frame 2210. Referring to Fig. 21, the guide rails 2211a, 2211b are formed only on a part of the inside of the leg frame 2210, and jaws are formed on the remaining part to block the movement of the guide rollers 2540a, 2540b. This can block the lower leg massage parts 2000ab, 2000bb from moving beyond a limit point, and can prevent the lower leg massage parts 2000ab, 2000bb from completely separating from the upper leg massage parts 2000aa, 2000ba.

[0222] Meanwhile, in order to more appropriately guide the movement of the guide bars 2530a and 2530b, the leg massager 2000 may further include guide wheels 2551a and 2551b and guide wheel brackets 2552a and 2552b that accommodate and support the guide wheels 2551a and 2551b. Referring to FIG. 22, at least one guide wheel 2551a and 2551b may be disposed inside the guide wheel brackets 2552a and 2552b. The outer surfaces of the guide wheels 2551a and 2551b may be formed concavely on the inside, and the guide bars 2530a and 2530b may be inserted and positioned to correspond to the concave region. Therefore, when the guide bars 2530a and 2530b move up and down, the guide wheels 2551a and 2551b may support the guide bars 2530a and 2530b so that they do not deviate from the movement path. As a result, the guide wheels 2551a, 2551b support the guide bars 2530a, 2530b to prevent the guide bars 2530a, 2530b from shaking while they are moving, and can guide the guide bars 2530a, 2530b to move in the appropriate direction. Therefore, the lower leg massage parts 2000ab, 2000bb can also move in the appropriate direction by the guide bars 2530a, 2530b without shaking.

[0223] FIG. 23 illustrates a foot massager 2600 according to an embodiment of the present invention.

[0224] The lower leg massage parts 2000ab, 2000bb may include foot massage parts 2610, 2630 on one side. Preferably, the foot massage parts 2610, 2630 may be provided on the lowest end or the lowest surface of the lower leg massage parts 2000ab, 2000bb.

[0225] The foot massage units 2610 and 2630 may include at least one foot massage module (or massage unit for massaging the feet) and at least one foot massage actuator (or foot driver) for driving the foot massage module. For example, the first leg massage unit 2000a may include a first foot massage unit 2610 arranged in an area corresponding to the sole of one leg of the user. The second leg massage unit 2000b may include a second foot massage unit 2630 arranged in an area corresponding to the sole of the other leg of the user.

[0226] The first foot massage unit 2610 may include at least one of the first foot massage module 2612 and the second foot massage module 2613. The first foot massage module 2612 and the second foot massage module 2613 are arranged (or disposed) at the front and rear of the first foot massage unit 2610, respectively, to provide an overall massage to the sole of one leg of the user. Also, the first foot massage unit 2610 may include first foot massage actuators 2611 and 2613 for driving at least one foot massage module. The first foot massage actuators 2611 and 2613 are disposed at the front of the first foot massage unit 2610 and at the front of the first foot massage module 2612 to drive at least one foot massage module. In this case, the front of the first foot massage unit 2610 and the front of the first foot massage module 2612 may be an area corresponding to the toes of one leg among the entire area of ​​the first foot massage unit 2610.

[0227] The second foot massage unit 2630 may include at least one of the third foot massage module 2632 and the fourth foot massage module 2633. For example, the third foot massage module 2632 and the fourth foot massage module 2633 may be arranged (or disposed) at the front and rear of the second foot massage unit 2630, respectively, to provide an overall massage to the sole of the user's other leg. Also, the second foot massage unit 2630 may include a second foot massage actuator 2631 for driving at least one foot massage module. The second foot massage actuator 2631 may be disposed at the front of the second foot massage unit 2630 and at the front of the third foot massage module 2632 to drive at least one foot massage module. In this case, the front of the second foot massage unit 2630 and the front of the third foot massage module 2632 may be an area corresponding to the toes of the other leg among the entire area of ​​the second foot massage unit 2630.

[0228] As described above, the first and second foot massage units 2610 and 2630 include two foot massage modules and one foot massage actuator, but are not limited thereto. For example, each of the first and second foot massage units may include a plurality of foot massage modules (e.g., three or more), and the leg massage modules may be arranged in a straight line as shown in FIG. 23. In this case, the straight line may be a line that crosses the sole of the foot. Each of the first and second foot massage units may include a single foot massage actuator and drive all of the multiple foot massage modules via the single foot massage actuator.

[0229] Meanwhile, the foot massage module may have at least one protrusion formed on a surface thereof, so that the foot massage module can provide a massage to the soles of the user's feet by rotating.

[0230] Alternatively, the foot massage module may be a roller having an arc-shaped surface, so that the foot massage module can provide a massage to the soles of the user's feet by rotating.

[0231] Meanwhile, as an optional embodiment, a cam may be attached to the foot massage actuator. Thus, the foot massage unit can provide acupressure massage to the toes of the user using the cam without rolling massage. Also, by attaching a cam to the foot massage actuator, it is possible to improve spatial efficiency compared to a case where a foot massage actuator is separately provided.

[0232] FIG. 24 is a diagram showing a pinch prevention sensor (S) in the leg massage part 2000 according to an embodiment of the present invention.

[0233] At least one anti-pinch sensor (S; or safety sensor) may be provided at at least one of the sides, rear, and between the upper leg massage parts 2000aa, 2000ba and the lower leg massage parts 2000ab, 2000bb of the leg massage part 2000. In this case, the anti-pinch sensor (S) may be a sensor for recognizing that a part of the user's body is pinched around the leg massage parts 2000a, 2000b.

[0234] In this case, the anti-pinch sensor (S) provided may be, but is not limited to, a static touch sensor.

[0235] If the anti-pinch sensor (S) is attached to the side of the leg massage unit 2000, it can detect that a part of the user's body is pinched between the leg massage units 2000a and 2000b when the leg massage unit 2000 rotates. Alternatively, it can detect that a part of the user's body is pinched between the leg massage unit 2000 and the body massage unit 1100 when the leg massage unit 2000 rotates.

[0236] When a pinch prevention sensor (S) is attached to the rear surface of the leg massage unit 2000, it can detect that a part of the user's body is pinched by the rear surface of the leg massage unit 2000 when the leg massage unit 2000 rotates.

[0237] When a pinch prevention sensor (S) is attached between the upper leg massage portion 2000aa, 2000ba and the lower leg massage portion 2000ab, 2000bb, when adjusting the distance between the upper leg massage portion 2000aa, 2000ba and the lower leg massage portion 2000ab, 2000bb, it can recognize that a part of the user's body is pinched between the upper leg massage portion 2000aa, 2000ba and the lower leg massage portion 2000ab, 2000bb.

[0238] Therefore, if the user's body becomes pinched at a specific position in the massage device 1000 while the leg massage section 2000 is rotating, the pinch prevention sensor (S) can recognize this, thereby stopping the massage device 1000 and preventing a safety accident.

[0239] Meanwhile, the anti-pinch sensor (S) may be extended to have a length, that is, the anti-pinch sensor (S) may be a linear sensor.

[0240] When the leg massage unit 2000 is rotated or its length is adjusted, it is impossible to know which part of the leg massage unit 2000 a person's body may be caught in, so if the anti-pinch sensor (S) is extended in the length direction, the area that can detect whether the user's body comes into contact with the sensor may be expanded, so the user can use the massage device 1000 more safely.

[0241] As an alternative embodiment, the anti-pinch sensor (S) may be provided on each of the upper leg massage parts 2000aa, 2000ba and the lower leg massage parts 2000ab, 2000bb. At least one anti-pinch sensor (S) may be provided on each side. For example, the anti-pinch sensor (S) may be provided on both sides of the upper leg massage parts 2000aa, 2000ba, or may be located on the left and right sides of the rear side of the upper leg massage parts 2000aa, 2000ba. The anti-pinch sensor (S) may also be located on a surface between the upper leg massage parts 2000aa, 2000ba and the lower leg massage parts 2000ab, 2000bb. The anti-pinch sensor (S) may also be provided on both sides of the lower leg massage parts 2000ab, 2000bb.

[0242] Therefore, even if a part of the user's body, such as a leg, becomes caught between any of the adjacent portions of the leg massage parts 2000 while the massage device 1000 is in operation, this can be recognized.

[0243] Although not shown in the drawings, the leg massager 2000 may further include a sensor for controlling the length of the leg massager 2000 .

[0244] In one embodiment, the leg massage unit 2000 may include at least one limit sensor on the leg frame 2210. The limit sensor may be a sensor for determining a length adjustment limit of the leg massage unit 2000. Alternatively, the limit sensor may be a sensor for determining a reference position of the leg massage unit 2000. For example, the limit sensor may be, but is not limited to, a Hall sensor.

[0245] By including the limit sensor, the upper leg massage parts 2000aa, 2000ba and the lower leg massage parts 2000ab, 2000bb do not need to be separated by more than a certain limit, thereby preventing safety accidents and preventing the lower leg massage parts 2000ab, 2000bb from being completely separated and detached from the upper leg massage parts 2000aa, 2000ba.

[0246] In another embodiment, the leg massage unit 2000 may include an encoder. Therefore, the encoder can be used to recognize the distance between the upper leg massage units 2000aa, 2000ba and the lower leg massage units 2000ab, 2000bb, thereby determining the length adjustment limit of the leg massage unit 2000. That is, the encoder can recognize the distance between the upper leg massage units 2000aa, 2000ba and the lower leg massage units 2000ab, 2000bb, and when the distance reaches a certain limit, the relative movement of the upper leg massage units 2000aa, 2000ba and the lower leg massage units 2000ab, 2000bb can be stopped.

[0247] In one embodiment, the leg massage units 2000a and 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 leg length of one side, and the second leg massage unit 2000b may include a second measurement sensor for measuring the leg length of the other side.

[0248] Preferably, each measurement sensor may include at least one sensor (or sub-measurement sensor) of a first sensor (or a first sub-measurement sensor) and a second sensor (or a second sub-measurement sensor) for measuring the leg length of the user.

[0249] For example, the first sensor may be an electrostatic touch sensor. The first sensor may be for roughly measuring the leg length of the user. Thus, the leg length of the user can be measured through the first sensor, and the length of the leg massage parts 2000a, 2000b can be adjusted accordingly.

[0250] The first sensor may measure the leg length by recognizing that the user's body is in contact with the first sensor. Thus, the first sensor can measure the leg length of the user depending on whether the user's body is in contact with the first sensor, and based on this, the massage device 1000 can adjust the length of the leg massage parts 2000a, 2000b. Although the accuracy is reduced, the length of the leg massage parts 2000a, 2000b can be adjusted quickly and roughly.

[0251] In order to precisely measure the length of the leg massage parts 2000a, 2000b, the leg massage parts 2000a, 2000b according to the present invention may further include a second sensor.

[0252] For example, the second sensor may be a photo sensor or a load sensor. The second sensor may be for precisely measuring the leg length of the user. Thus, the massage device 1000 may roughly measure the leg length of the user using the first sensor, adjust the length of the leg massage parts 2000a and 2000b accordingly, and then precisely measure the leg length of the user using the second sensor, and adjust the length of the leg massage parts 2000a and 2000b accordingly.

[0253] FIG. 25 is a diagram showing a photosensor in a leg massage unit according to an embodiment of the present invention, and FIG. 26 is an enlarged view of D in FIG.

[0254] 25 and 26, in one embodiment, the second sensor may be a photosensor (PS). Preferably, the second sensor may be a mechanical photosensor. In this way, when the photosensor (PS) is used, the leg length of the user can be measured more precisely than when only the first sensor is used, as described above. Also, the photosensor (PS) is provided on each of the leg massage parts on both sides, so that the leg lengths of both the user can be measured precisely.

[0255] For example, the photosensor (PS) may be located under the leg massage parts 2000a and 2000b. Thus, the photosensor (PS) can measure the leg length of the user more precisely. That is, referring to Fig. 26, the photosensor (PS) is located under the leg massage parts 2000a and 2000b on both sides, and when the leg massage parts 2000a and 2000b move, the disk member rotates due to the movement, and the degree of light reception that changes due to the rotation of the disk member is measured, so that the leg length of the user can be measured more precisely.

[0256] However, without being limited to these, it is of course possible to measure the leg length of a user by using other types of photosensors (PS) or by the principle by which existing photosensors (PS) are driven.

[0257] In another embodiment, the second sensor may measure leg length by measuring the load exerted by the user's leg.

[0258] For example, the control unit 1400 of the massage device 1000 can recognize the length of the leg massage parts 2000a, 2000b as the leg length of the user when a load of a preset size is applied to the second sensor while adjusting the distance between the upper leg massage parts 2000aa, 2000ba and the lower leg massage parts 2000ab, 2000bb. Therefore, when a load of a preset size is applied to the second sensor while finely adjusting the distance between the upper leg massage parts 2000aa, 2000ba and the lower leg massage parts 2000ab, 2000bb, the massage device 1000 can recognize the distance of the leg massage parts 2000a, 2000b as the leg length of the user, and in this case, can adjust the length of the leg massage parts 2000a, 2000b to correspond to the leg length of the user.

[0259] Meanwhile, the first and second sensors may be located under the leg massage parts 2000a and 2000b, preferably at positions corresponding to the soles of the user's feet, so that the leg length of the user can be precisely measured based on the change in length of the leg massage parts 2000a and 2000b.

[0260] In the following, the method of operation of the massage device 1000 described above will be explained in detail.

[0261] A method of operating the massage device 1000 according to the present invention may include the steps of receiving user input, recognizing physical information for at least a portion of the user's body, adjusting the massage device based on the physical information, and providing a massage to the user using the adjusted massage device.

[0262] FIG. 27 shows a diagram illustrating the stretching and exercise modes provided by the massage device according to one embodiment of the present disclosure.

[0263] The massage device 1000 may provide a stretch mode for stretching the user's body and a leg rehabilitation mode (or cycle mode) for exercising the user's legs. In this case, the stretch mode may be a mode for stretching at least one of the user's legs, waist, and buttocks (e.g., hip area). The cycle mode may be a mode used by a user having normal legs for leg exercise, or a mode used by a user having abnormal legs due to various injuries such as a knee injury for leg rehabilitation.

[0264] For example, the stretch mode may include at least one of an iliopsoas stretch mode (or iliopsoas relaxation mode) for stretching the iliopsoas muscle of the leg, a hamstring stretch mode (or hamstring relaxation mode) for stretching the hamstring of the leg, a waist stretch mode (or rolling stretch mode) for stretching the waist, and a piriformis stretch mode (piriformis relaxation mode) for stretching the piriformis muscle of the buttocks.

[0265] Specifically, the control unit 1400 can execute each stretch mode and / or cycle mode based on the user's response, or can execute each stretch mode and / or cycle mode automatically, where the user's response may be a response (or signal) for executing the stretch mode and / or cycle mode.

[0266] The control unit 1400 can provide each stretch mode and / or cycle mode to the user by controlling the operation of the massage device 1000 according to a massage map for each stretch mode and / or cycle mode. At this time, the massage map can be preset from various objects and stored in the memory 1430. The objects are diverse, such as users who use the massage device, managers, and / or employees and doctors of various companies such as manufacturers, sales companies, distributors, and developers of the massage device.

[0267] For example, the control unit 1400 may provide the iliopsoas stretch mode to the user by controlling the operation of the massage device 1000 based on the massage map for the iliopsoas stretch mode. Through this, the control unit 1400 may stretch the iliopsoas muscle of the user to relax the iliopsoas muscle, thereby straightening the bent lower back and reducing excessive stress transmitted to the lumbar vertebrae, thereby relieving lower back pain.

[0268] As another example, the control unit 1400 may provide a hamstring stretch mode to a user by controlling the operation of the massage device 1000 based on a massage map for the hamstring stretch mode, whereby the control unit 1400 may stretch the user's hamstrings to relax the hamstring muscles, thereby preventing muscle shortening and injury.

[0269] As another example, the control unit 1400 may provide a waist stretch mode to the user by controlling the operation of the massage device 1000 based on the massage map for the waist stretch mode. Through this, the control unit 1400 may stretch the user's waist and relax the muscles around the lumbar vertebrae, thereby increasing the mobility of the muscles around the lumbar vertebrae and reducing the lower back pain.

[0270] As another example, the control unit 1400 may provide the piriformis muscle stretch mode to the user by controlling the operation of the massage device 1000 based on the massage map for the piriformis muscle stretch mode. Through this, the control unit 1400 may stretch the user's buttocks (or piriformis muscle) and relax the muscles around the buttocks (or piriformis muscle), thereby reducing pain in the lower back and buttocks, numbness in the legs, sciatica, etc., and improving mobility of the hip joint of the lower body.

[0271] The control unit 1400 can provide the cycle mode to the user by controlling the operation of the massage device 1000 based on the massage map for the cycle mode. Through this, the massage device 1000 can exercise the normal leg to guide the normal leg to be maintained in a healthy state, and can rehabilitate the abnormal leg to guide the abnormal leg to be restored to a healthy state. The massage device 1000 can prevent joint damage by exercising the leg (or rehabilitating the foot) through repeated joint movements to maintain and enhance the flexibility and movement of the joints (pelvis, knee, ankle). In other words, the cycle mode can be a leg exercise mode as well as a leg rehabilitation mode (or knee rehabilitation mode).

[0272] FIG. 28 shows a diagram for explaining an example of the massage mode shown in FIG. 27, and FIG. 29 shows an example for explaining the reclining operation of the control unit according to an embodiment of the present disclosure.

[0273] 28 and 29, the control unit 1400 can recline the massage device 1000 (S2810) and provide a stretching mode and / or an exercise mode to the user with the massage device 1000 reclined (S2830).

[0274] First, the control unit 1400 can recline the massage device 1000 by tilting the body massage unit 1100 backward of the massage device 1000 and tilting (or rotating) each leg massage unit toward the upper side of the massage device 1000 (S2810). The reclined massage device 1000 may be in a state where the body massage unit 1100 is tilted toward the rear of the massage device 1000 and the leg massage unit 2000 is rotated toward the upper side of the massage device 1000.

[0275] The control unit 1400 can adjust the length of each leg massage unit based on the length of each leg while tilting each leg massage unit. The length adjustment operation of each leg massage unit is as described above, so a detailed description will be omitted.

[0276] Thereafter, the control unit 1400 can provide the user with the stretch mode and / or the exercise mode by controlling the operation of the massage device 1000 according to the stretch mode and / or the exercise mode when the massage device 1000 is reclined (S2830). For example, the control unit 1400 can perform an operation corresponding to the stretch mode and / or the exercise mode when the massage device 1000 is reclined.

[0277] Through this, the control unit 1400 reclines the massage device 1000 to secure space for stretching the user's legs and space for exercising the user's legs, thereby eliminating the spatial restrictions for stretching the user's legs and exercising the legs, and thereby increasing the leg stretching effect and leg exercise effect.

[0278] In addition, the control unit 1400 can provide a relaxation massage to relax the body of the user through the massage units (e.g., at least one of the body massage unit 1100, the arm massage unit 1200, and the leg massage unit 2000) when the massage device 1000 is reclined, and then provide a stretch mode and / or an exercise mode. In this case, the relaxation massage may be a massage with a preset massage intensity and speed. For example, the relaxation massage may be provided at an average massage intensity and average massage speed among the massage intensities and speeds that the massage device 1000 can provide, or at a minimum massage intensity and minimum massage speed. Through this, the control unit 1400 can relax the user's body to prevent injury due to the stretch mode and / or the exercise mode, and increase the leg stretching effect and leg exercise effect.

[0279] As described above, the control unit 1400 provides the user with the stretch mode and / or cycle mode after reclining the massage device 1000 and providing a relaxation massage, but is not limited thereto. For example, the control unit 1400 may provide the stretch mode and / or exercise mode after performing at least one of the operations of reclining the massage device 1000 and providing a relaxation massage.

[0280] FIG. 30 shows a flow chart for explaining the piriformis muscle stretch mode shown in FIG.

[0281] The control unit 1400 can provide the piriformis muscle stretch mode to the user by controlling the operation of the massage device 1000 in accordance with the operation corresponding to the piriformis muscle stretch mode.

[0282] First, the control unit 1400 can stretch the user's legs by increasing the length of one of the first leg massage unit 2000a and the second leg massage unit 2000b via the leg length adjustment module 2500 (S3010).

[0283] The control unit 1400 can inflate an air cell of any one of the leg massage units to fix the user's legs while increasing the length of any one of the leg massage units. For example, the control unit 1400 can inflate a leg air cell included in at least one of the upper leg massage unit and the lower leg massage unit of any one of the leg massage units. Specifically, the control unit 1400 can first inflate a leg air cell (e.g., at least one of the first and second sub-foot air cells) included in the lower leg massage unit of any one of the leg massage units, and then later inflate a calf air cell (e.g., at least one of the first and second sub-calf air cells) included in the upper leg massage unit of any one of the leg massage units.

[0284] As described above, the control unit 1400 inflates the air cells of any one of the leg massage units while increasing the length of any one of the leg massage units, but is not limited thereto. For example, the control unit 1400 may increase the length of any one of the leg massage units after inflating the air cells of any one of the leg massage units.

[0285] Through this, the control unit 1400 can fully extend the piriformis muscle of the leg by traction of the leg to be stretched, which is the leg corresponding to the leg massage unit among one leg and the other leg of the user. At this time, the control unit 1400 can accurately stretch the leg to be stretched by accurately gripping the lower part of the leg to be stretched and pulling the leg to be stretched, compared to when the lower part of the leg to be stretched is not fixed. In addition, the control unit 1400 can improve the stretching effect on the leg to be stretched by further gripping the upper part of the leg to be stretched and continuously pulling the leg to be stretched.

[0286] The control unit 1400 may provide a massage to the user's buttocks by moving the massage module 1110 to the user's buttocks (S3030). For example, the control unit 1400 may move the massage module 1110 to a region of the main frame 1130 that corresponds to the user's buttocks. The control unit 1400 may protrude the massage module 1110 moved to the user's buttocks in a forward direction of the massage module 1110 to massage the user's buttocks. At this time, the forward direction of the massage module 1110 may be a direction in which the massage module 1110 approaches the user's body. In other words, the control unit 1400 may provide a finger pressure massage to the user's buttocks through the massage module 1110.

[0287] Thus, the control unit 1400 can provide a massage to the stretched piriformis muscle via the massage module 1110 to sufficiently relax the piriformis muscle.

[0288] FIG. 31 shows a diagram for explaining each operation of the piriformis muscle stretch mode shown in FIG.

[0289] The control unit 1400 can acquire the user's shoulder position through the massage module 1110 and then recline the massage device 1000 (or acquire the user's shoulder position through the massage module 1110 after reclining the massage device 1000 (Motion 1A)). At this time, the control unit 1400 can adjust the length of each leg massage part based on the length of each leg while reclining the massage device 1000 (or after performing the reclining operation) as described above.

[0290] After performing Motion 1A, the control unit 1400 can increase the length of either the first leg massage unit 2000a or the second leg massage unit 2000b through the leg length adjustment module 2500 while the massage device 1000 is reclined (Motion 1B).

[0291] First, before increasing the length of any one of the leg massage parts, the control unit 1400 can adjust (or change) the angle of any one of the leg massage parts through the leg angle adjustment module 1350 while the massage device 1000 is reclined (Motion 1B_1).

[0292] For example, the control unit 1400 can operate (or drive) a leg angle adjustment module corresponding to any one of the first and second leg angle adjustment modules 1350a, 1350b to adjust the angle of any one of the leg massage units.

[0293] Specifically, the control unit 1400 can adjust the angle of any one of the leg massage units by tilting the leg massage unit in at least one of clockwise and counterclockwise directions through a leg angle adjustment module corresponding to any one of the leg massage units. At this time, the control unit 1400 can finely operate the remaining leg angle adjustment modules other than the leg angle adjustment module corresponding to any one of the leg massage units among the first and second leg angle adjustment modules 1350a and 1350b. Through this, the control unit 1400 can fix the position of the remaining leg massage unit other than any one of the leg massage units among the first and second leg massage units 2000a and 2000b.

[0294] As an example, the control unit 1400 can maximize the length of the leg angle adjustment module corresponding to any one of the leg massage units and maximize the elevation of any one of the leg massage units, thereby maximizing the angle of any one of the leg massage units (Motion 1B_1a).

[0295] As another example, the control unit 1400 can reduce the length of a leg angle adjustment module corresponding to any one of the leg massage units to the maximum and lower any one of the leg massage units to the maximum, thereby decreasing the angle of any one of the leg massage units to the maximum (Motion 1B_1b).

[0296] Through this, the control unit 1400 can flex the hip joint of the user before extending the user's leg, thereby preventing physical injuries caused by extending the user's leg.

[0297] Thereafter, the control unit 1400 moves the massage module 1110 to a position corresponding to the user's buttocks while the angle of any one of the leg massage parts is adjusted before increasing the length of any one of the leg massage parts, and massages the user's buttocks through the massage module 1110 (Motion 1B_2).

[0298] 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 placing the massage module 1110 on the user's buttocks. As described above, the control unit 1400 moves the massage module 1110 based on the predicted position of the user's buttocks, but is not limited thereto. For example, the control unit 1400 can move the massage module 1110 based on a previously set position of the user's buttocks.

[0299] The control unit 1400 can provide a massage to the user's buttocks through the massage module 1110 disposed on the user's buttocks. At this time, the massage can be various massages (e.g., finger pressure massage, kneading massage, combined massage, etc.) for reducing tension in the user's buttocks, but for convenience of explanation, it will be assumed to be a tapping massage below. The tapping massage can be preset at various intensities and speeds that provide a soft massage feeling, such as being provided at the minimum intensity and minimum speed among the massage intensities and speeds that the massage module 1110 can provide, or being provided at the average intensity and average speed.

[0300] Through this, the control unit 1400 can provide a massage to reduce tension in the user's buttock muscles (e.g., piriformis muscle) before stretching and relaxing the muscles, thereby preventing injury to the user and side effects from piriformis muscle stretching.

[0301] As described above, the control unit 1400 moves the massage module 1110 in a state where the angle of any one of the leg massage units is adjusted, but is not limited thereto. For example, the control unit 1400 may move the massage module 1110 while 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).

[0302] Finally, after completing the Motion 1B_2 operation, the control unit 1400 can increase the length of any one of the leg massage parts through the leg length adjustment module 2500 (Motion 1B_3). At this time, the control unit 1400 can end the Motion 1B_2 operation by stopping the operation of the massage module 1110. Before stopping the operation of the massage module 1110, the control unit 1400 can move the massage module 1110 in the rear direction of the massage module 1110 as far as possible, and then stop the massage module 1110.

[0303] For example, the control unit 1400 can operate (or drive) a leg length adjusting module corresponding to one of the first and second leg length adjusting modules 2500a and 2500b to increase the length of one of the leg massage units. At this time, the control unit 1400 can inflate the air cells of one of the leg massage units as described above.

[0304] Specifically, the control unit 1400 can increase the length of one of the leg massage units by moving one of the leg massage units toward the lower side of the other leg massage unit through the leg length adjusting module corresponding to the one of the leg massage units. At this time, the control unit 1400 can finely operate a remaining leg length adjusting module different from the leg length adjusting module corresponding to one of the leg massage units among the first and second leg length adjusting modules 2500a and 2500b. Through this, the control unit 1400 can fix the length of the remaining leg massage unit different from one of the leg massage units among the first and second leg massage units 2000a and 2000b.

[0305] The leg length adjustment operation will be described in detail below.

[0306] The control unit 1400 can increase the length of any one of the leg massage parts by moving any one of the leg massage parts in a downward direction of any one of the leg massage parts based on a reference length for increasing the length of any one of the leg massage parts.

[0307] For example, the reference length is a standard indicating the degree to which the leg to be stretched is pulled, and may refer to the moving length (or moving distance) of moving any one of the leg massage parts downward. The reference length may be a length that allows the leg to be stretched sufficiently and may be preset according to various objects and stored in the memory 1430. For example, the reference length may be set in various ways, such as about 5 cm to 10 cm.

[0308] As described above, the reference length may be preset, but is not limited thereto. For example, the control unit 1400 may determine a customized reference length customized for a user based on a leg length corresponding to one of the leg massage units of one leg and the other leg of the user as the reference length. Specifically, the memory 1430 may store a matching table in which arbitrary leg lengths and arbitrary reference lengths are matched with each other. The control unit 1400 may compare the leg length of the user with the matching table and determine an arbitrary reference length corresponding to the leg length among the arbitrary reference lengths included in the matching table as the customized reference length. The control unit 1400 may determine the customized reference length as a reference length for adjusting (or increasing) the length of one of the leg massage units. The control unit 1400 may increase the length of one of the leg massage units based on the reference length customized for the user.

[0309] As described above, the control unit 1400 increases the length of one of the leg massage parts after completing the Motion 1B_2 operation, which is a massage operation for massaging the buttocks of the user, but is not limited to this. For example, the control unit 1400 may increase the length of one of the leg massage parts while massaging at least a part of the user's body after completing the Motion 1B_2 operation.

[0310] Specifically, after completing the Motion 1B_2 operation, the control unit 1400 may change the position of the massage module 1110 to provide a massage to at least a part of the user's body. In this case, the control unit 1400 may provide a massage to body parts of the user excluding the user's buttocks through the massage module 1110. The control unit 1400 may increase the length of any one of the leg massage parts after providing a massage through the massage module 1110 or while providing a massage.

[0311] In addition, the control unit 1400 can fix the user's pelvis by expanding the pelvis air cells of the body massage unit 1100 by a preset expansion degree while increasing the length of any one of the leg massage units. At this time, the pelvis air cells can be arranged in areas corresponding to the user's pelvis, which are on both sides of the area where the user sits, among the entire area of ​​the massage device 1000.

[0312] As described above, the control unit 1400 inflates the pelvis air cell while increasing the length of any one of the leg massage parts, but is not limited thereto. For example, the control unit 1400 may inflate the pelvis air cell before increasing the length of any one of the leg massage parts.

[0313] Through this, the control unit 1400 can fix the user's legs and pelvis and stretch the leg to be stretched, thereby stretching the leg to be stretched more accurately than if the user's pelvis was not fixed, thereby improving the stretching effect on the leg to be stretched.

[0314] As described above, the control unit 1400 executes the motions 1B_1, 1B_2, and 1B_3 in sequence, but is not limited thereto. For example, the control unit 1400 can adjust the operation order of the motions 1B_1, 1B_2, and 1B_3 and execute them freely (or randomly), or execute the motions 1B_1, 1B_2, and 1B_3 simultaneously.

[0315] When Motion 1B is executed, the control unit 1400 can provide a massage to the user's buttocks through the massage module 1110 (Motion 1C). In this case, the control unit 1400 can drive the massage module 1110 when the operation of the massage module 1110 is stopped, and move the massage module 1110 to the user's buttocks when the position of the massage module 1110 does not correspond to the user's buttocks, thereby providing a massage to the user's buttocks.

[0316] First, the control unit 1400 may massage the user's buttocks by protruding the massage module 1110 in a forward direction of the massage module 1110 based on a reference intensity for massaging the user's buttocks (Motion 1C_1). At this time, the reference intensity may refer to a protruding degree of the massage module 1110 based on a reference indicating a massage intensity for acupressure on the user's buttocks. The reference intensity may be a massage intensity that can sufficiently relax the user's buttocks, and may be preset according to various objects and stored in the memory 1430. For example, the reference intensity may be variously set, such as an intensity for protruding the massage module 1110 by about 4 cm to 8 cm.

[0317] As described above, the reference intensity may be preset, but is not limited thereto. For example, the control unit 1400 may determine a customized reference intensity customized for a user based on at least one of the user's biometric information, the massage device usage history, and the user's preference information as the reference intensity.

[0318] Thereafter, the control unit 1400 may provide an additional massage to the user's buttocks by reciprocating the massage module 1110 while the massage module 1110 is in the protruding state (Motion 1C_2). At this time, the control unit 1400 may provide an additional massage by repeatedly providing the additional massage to the user's buttocks by repeating the reciprocating motion. The reciprocating motion may refer to the action of kneading and massaging the user's buttocks through the massage module 1110.

[0319] For example, the control unit 1400 may move the massage module 1110 in an upward direction of the massage module 1110 by a preset first distance, and then move the massage module 1110 in a downward direction of the massage module 1110 by a preset second distance, thereby causing the massage module 1110 to reciprocate. The first and second distances may be preset by various objects and stored in the memory 1430. The first and second distances may be set to be different from each other or the same. 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.

[0320] As described above, the control unit 1400 reciprocates the massage module 1110 in the upward and downward directions of the massage module 1110, but is not limited thereto. For example, the control unit 1400 can reciprocate the massage module 1110 in the forward and backward directions of the massage module 1110. In this case, the forward direction of the massage module 1110 may be a direction from the rear of the massage module 1110 to the front of the massage module 1110, and the backward direction of the massage module 1110 may be a direction from the front of the massage module 1110 to the rear of the massage module 1110. The front of the massage module 1110 may be a part that is disposed to contact the user and contacts the user's body.

[0321] Specifically, the control unit 1400 can move the massage module 1110 back and forth by further protruding the massage module 1110 in the forward direction of the massage module 1110 by a first distance while the massage module 1110 is protruding forward of the massage module 1110, and then retracting the massage module 1110 in the rear direction of the massage module 1110 by a second distance.

[0322] When the user's buttocks are additionally massaged through the reciprocating motion of the massage module 1110, the control unit 1400 can reduce the length of any one of the leg massage units by a preset length and maximally expand the pelvis air cell of the body massage unit 1100 to strongly fix the user's pelvis. For example, the control unit 1400 can maximally expand the pelvis air cell while or before reciprocating the massage module 1110.

[0323] Through this, the control unit 1400 firmly fixes the user's pelvis while reciprocating the massage module 1110, so that an additional massage can be accurately provided to the user's buttocks by additionally massaging the user's buttocks.

[0324] As described above, the control unit 1400 executes the piriformis muscle stretching motion (Motions 1A, 1B, and 1C) through any one of the leg massage units, but is not limited thereto. For example, the control unit 1400 may execute the piriformis muscle stretching motion (Motions 1A, 1B, and 1C) through any one of the leg massage units, and then execute the piriformis muscle stretching motion for the remaining leg massage units. In this case, the piriformis muscle stretching motion for the remaining leg massage units may be the same as the motions 1A, 1B, and 1C.

[0325] Furthermore, the control unit 1400 can sequentially and repeatedly execute the piriformis muscle stretching operation for each leg massage unit described above.

[0326] Through this, the control unit 1400 can stretch both of the user's legs and both of his / her buttocks in a balanced manner, and can repeatedly stretch to generally relax the user's legs and buttocks, thereby sufficiently stretching and relaxing the user's piriformis muscle.

[0327] In addition, the control unit 1400 may provide a thermal massage by increasing the temperature of the massage module 1110 while providing a massage to the user's buttocks through the massage module 1110 during the piriformis muscle stretching operation.

[0328] Through this, the control unit 1400 provides a warm sensation to the user's buttocks to stretch and relax the user's buttocks, so that the user's buttocks are stretched and relaxed more than if no warm sensation was provided, and injury due to stretching and relaxation can be prevented.

[0329] FIG. 32 shows a diagram for explaining the body air cells and leg air cells included in the body massage portion according to one embodiment of the present disclosure.

[0330] The body massage portion 1100 may include body air cells 1600 that massage (or apply pressure) to the user's body.

[0331] For example, the body air cell 1600 may include at least one of a shoulder air cell corresponding to the user's shoulder, a back air cell corresponding to the user's back, a pelvis air cell corresponding to the user's pelvis, a thigh air cell corresponding to the user's thigh, and a perineum air cell corresponding to the user's perineum.

[0332] Specifically, the body air cell 1600 may include a first body air cell 1610 disposed on one side of the body massage unit 1100 to massage one side of the user's body, a second body air cell 1630 disposed on the other side of the body massage unit 1100 to massage the other side of the user's body, and a third body air cell 1650 disposed between the one side and the other side of the body massage unit 1100 to massage between the one side and the other side of the user's body. The first body air cell 1610 may be an air cell corresponding to the first leg massage unit 2000a, and the second body air cell 1610 may be an air cell corresponding to the second leg massage unit 2000b.

[0333] The first body air cell 1610 can include at least one of a first shoulder air cell 1611, a first back air cell 1613, a first pelvis air cell 1615, and a first thigh air cell 1617, and the second body air cell 1630 can include at least one of a second shoulder air cell 1631, a second back air cell 1633, a second pelvis air cell 1635, and a second thigh air cell 1637.

[0334] The first shoulder air cell 1611 is disposed in a region (e.g., an upper end region of one side of the body massage unit 1100) corresponding to one side of the user's shoulder among the entire region of one side of the body massage unit 1100, so as to massage one side of the user's shoulder. The second shoulder air cell 1631 is disposed in a region (e.g., an upper end region of the other side of the body massage unit 1100) corresponding to the other side of the user's shoulder among the entire region of the other side of the body massage unit 1100, so as to massage the other side of the user's shoulder. At this time, the first and second shoulder air cells 1611, 1631 can massage (or fix) the user's shoulder by applying pressure to both sides of the user's shoulder (or both upper sides of the shoulder).

[0335] The first back air cell 1613 is disposed in a region corresponding to one side of the user's back among the entire region of one side of the body massage unit 1100 (for example, a region between the upper end of one side and the lower end of the one side of the body massage unit 1100) to massage one side of the user's back. The second back air cell 1633 is disposed in a region corresponding to the other side of the user's back among the entire region of the other side of the body massage unit 1100 (for example, a region between the upper end of the other side and the lower end of the other side of the body massage unit 1100) to massage the other side of the user's back. At this time, the first and second back air cells 1613, 1633 pressurize the rear surface of the user's back to massage the user's back, thereby pushing (or moving) the user's back in the forward direction of the body massage unit 1100.

[0336] The first pelvis air cell 1615 is arranged in a region (e.g., a lower end region on one side of the body massage unit 1100) corresponding to one side of the user's pelvis among the entire region on one side of the body massage unit 1100, so as to massage one side of the user's pelvis. The second pelvis air cell 1635 is arranged in a region (e.g., a lower end region on the other side of the body massage unit 1100) corresponding to the other side of the user's pelvis among the entire region on the other side of the body massage unit 1100, so as to massage the other side of the user's pelvis. At this time, the first and second pelvis air cells 1615, 1635 can apply pressure to both sides of the user's pelvis to massage (or fix) the user's pelvis.

[0337] The first thigh air cell 1617 is arranged in an area corresponding to the thigh of one leg of the user among the entire area on one side of the body massage unit 1100 (or an area on one side of the center of the lower end central area of ​​the body massage unit 1100) to massage the thigh of one leg of the user. The second thigh air cell 1637 is arranged in an area corresponding to the thigh of the other leg of the user among the entire area on the other side of the body massage unit 1100 (or an area on the other side of the center of the lower end central area of ​​the body massage unit 1100) to massage the thigh of the other leg of the user. At this time, the first and second thigh air cells 1617, 1637 pressurize the rear surface of the user's thigh to massage the thighs of one side and the other side of the user, thereby pushing the user's thigh in the upward direction of the body massage unit 1100.

[0338] The third body air cell 1650 is disposed in a region corresponding to the perineum of the user (for example, the front central region of the body massage unit 1100) among the entire region between one side and the other side of the body massage unit 1100 to massage the perineum of the user. At this time, the perineum air cell, which is the third body air cell 1650, can pressurize the perineum of the user to push the user's body in the upward direction of the body massage unit 110.

[0339] The leg massage portion 2000 may also include leg air cells 1700 that massage the user's feet.

[0340] For example, the leg air cell 1700 may include a first leg air cell 1710 corresponding to a first leg massage portion 2000a (or the leg on one side of the user), and a second leg air cell 1730 corresponding to a second leg massage portion 2000b (or the leg on the other side of the user).

[0341] Specifically, the first leg massage part 2000a includes a first leg air cell 1710 arranged in at least a portion of the first leg massage part 2000a, and the second leg massage part 2000b includes a second leg air cell 1730 arranged in at least a portion of the second leg massage part 2000b.

[0342] Each leg air cell 1710, 1730 may include at least one of a calf air cell corresponding to the user's calf and a foot air cell corresponding to the user's foot.

[0343] For example, the first leg air cell 1710 can include at least one of a first calf air cell 1711 and a second foot air cell 1713, and the second leg air cell 1730 can include at least one of a second calf air cell 1731 and a second foot air cell 1733.

[0344] The first calf air cell 1711 is positioned in an area of ​​the entire area of ​​the first leg massage unit 2000a corresponding to the calf of one of the user's legs (e.g., the upper end area of ​​the first leg massage unit 2000a) to massage the user's calf.

[0345] For example, the first calf air cell 1711 may include at least one of a first sub-calf air cell 1711a arranged in a region corresponding to the side of the calf of one leg to massage (or pressurize) the side of the calf, and a second sub-calf air cell 1711b arranged in a region corresponding to the rear of the calf of one leg to massage the rear of the calf. In this case, the first sub-calf air cell 1711a may pressurize both sides of the calf of the one leg to massage (or fix) the user's calf.

[0346] The second calf air cell 1731 is the same as the above-mentioned first calf air cell 1711 applied to the second leg massage portion 2000b, and therefore a detailed description thereof will be omitted.

[0347] The first leg air cell 1713 is arranged in an area of ​​the entire area of ​​the second leg massage unit 2000a corresponding to the foot of one of the user's legs (e.g., the lower end area of ​​the first leg massage unit 2000a) to massage the user's foot.

[0348] For example, the first foot air cell 1713 may include at least one of a first sub foot air cell 1713a arranged in an area corresponding to the side of the foot (or the instep) of one leg to massage (or pressurize) the side of the foot (or the instep) and a second sub foot air cell 1713b arranged in an area corresponding to the rear of the foot (or the heel, Achilles tendon) of one leg to massage (or pressurize) the rear of the foot (or the heel, Achilles tendon). In this case, the first sub foot air cell 1713a may pressurize both sides of the foot of the one leg to massage (or fix) the user's foot.

[0349] The second leg air cell 1733 is the same as the above-mentioned first leg air cell 1713 applied to the second leg massage portion 2000b, and therefore a detailed description thereof will be omitted.

[0350] FIG. 33 shows a flowchart for explaining the iliopsoas stretch mode shown in FIG. 27, and FIG. 34 shows diagrams for explaining each operation shown in FIG.

[0351] The control unit 1400 may provide the user with an iliopsoas stretch mode that stretches the iliopsoas muscle of the user's leg by controlling the operation of the massage device 1000 according to an operation corresponding to the iliopsoas stretch mode. In this case, the iliopsoas stretch mode may include a leg stretch operation that stretches the user's leg (or the iliopsoas muscle of the leg).

[0352] For example, the control unit 1400 can recline the massage device 1000 as in Motion 2A before performing the leg stretching motion (S3310).

[0353] Specifically, the control unit 1400 can adjust the angle of the leg massage unit 2000 by tilting (or tilting) the body massage unit 1100 toward the rear of the body massage unit 1100 based on the preset body angle, and then tilting the leg massage unit 2000 toward the upper side of the massage device 1000 based on the preset leg angle. The body angle and leg angle may be preset from various objects and stored in the memory 1430. The body angle may be any one of the minimum body angle and the maximum body angle between the ground and the body massage unit 1100, and may be an angle that is greater than the minimum body angle and smaller than the maximum body angle. The minimum body angle may be an angle at which the body massage unit 1100 is maximally inclined (maximally tilted) in the forward direction of the body massage unit 1100. The maximum body angle may be an angle at which the body massage unit 1100 is maximally inclined in the backward direction of the body massage unit 1100. The leg angle may be any one of the minimum leg angle and the maximum leg angle between the body massage unit 1100 and each leg massage unit, and may be an angle that is greater than the minimum leg angle and smaller than the maximum leg angle. The minimum leg angle may be an angle at which each leg massage unit is maximally inclined in the downward direction of the massage device 1000. The maximum leg angle may be an angle at which each leg massage unit is maximally inclined in the upward direction of the massage device 1000.

[0354] The control unit 1400 may execute a preliminary operation including at least one of an operation of providing a relaxation massage and an operation of measuring a leg length while the massage device 1000 is in a reclined position.

[0355] For example, the control unit 1400 can provide (or while providing) a relaxation massage to relax the user's body and measure the user's leg length.

[0356] The operation of providing a relaxation massage and the operation of measuring the leg length are as described above, and therefore detailed description thereof will be omitted. However, the control unit 1400 can move the massage module 1110 to a position corresponding to the user's buttocks while providing the relaxation massage. The massage module moving operation can be applied to the content described in Motion 1B_2, and therefore detailed description thereof will be omitted.

[0357] The control unit 1400 can execute a leg stretching action when the massage device 1000 is in a reclined position via the leg length adjustment module 2500 and the leg angle adjustment module 1350 (S3330).

[0358] The leg stretching motion may include a first leg stretching motion and / or a second leg stretching motion. The first leg stretching motion may stretch one leg of the user to stretch the iliopsoas muscle of the one leg. The second leg stretching motion may stretch the other leg of the user to stretch the iliopsoas muscle of the other leg.

[0359] For example, the control unit 1400 may sequentially and repeatedly execute the stretching motions of the first and second legs based on a preset number of repetitions. In this case, the number of repetitions may be preset from various objects and stored in the memory 1430. In the following, for convenience of explanation, it is assumed that the stretching motions of the first and second legs are not repeatedly executed.

[0360] First, the control unit 1400 can execute a stretching motion of the first leg as in Motion 2B (S3331).

[0361] For example, the control unit 1400 may adjust or maintain the length of the second leg massage unit 2000b as in Motion 2B-1, and increase the length of the first leg massage unit 2000a. In this case, the length of the first leg massage unit 2000a may refer to the length from one end to the other end of the first leg massage unit 2000a. The length of the second leg massage unit 2000b may refer to the length from one end to the other end of the second leg massage unit 2000b.

[0362] Specifically, the control unit 1400 may determine an adjustment length for adjusting the length of the first leg massage unit 2000a based on the length of one leg of the user. The control unit 1400 may adjust the length of the first leg massage unit 2000a based on the adjustment length. The length adjustment operation of the first leg massage unit 2000a will be described in detail below.

[0363] For ease of explanation, it is assumed below that the length of the first leg massage part 2000a is adjusted while the length of the second leg massage part 2000b is adjusted during a stretching motion of the first leg.

[0364] The control unit 1400 can adjust the angle of the first leg massage unit 2000a while maintaining the angle of the second leg massage unit 2000b as in Motion 2B-2. In this case, the angle of the first leg massage unit 2000a can refer to the angle between the first leg massage unit 2000a and the body massage unit 1100 (or the seat unit of the body massage unit). The angle of the second leg massage unit 2000b can refer to the angle between the second leg massage unit 2000b and the body massage unit 1100.

[0365] For example, the control unit 1400 may 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. The control unit 1400 may adjust the angle of the first leg massage unit 2000a based on the adjustment angle. The angle adjustment operation of the first leg massage unit 2000a will be described in detail below.

[0366] After performing the first leg stretching operation, the control unit 1400 may restore the position of the leg massage unit 2000. The angle and length of the restored leg massage unit 2000 may be the angle and length of the leg massage unit 2000 before the first leg stretching operation is performed.

[0367] Thereafter, the control unit 1400 may execute a stretching motion for the second leg as in Motion 2C (S3333).

[0368] For example, the control unit 1400 may adjust the length of the first leg massage part 2000a as in Motion 2C-1, or may increase the length of the second leg massage part 2000b while maintaining the length.

[0369] Specifically, the control unit 1400 may determine an adjustment length for adjusting the length of the second leg massage unit 2000b based on the length of the other leg of the user. The control unit 1400 may adjust the length of the second leg massage unit 2000b based on the adjustment length. The length adjustment operation of the second leg massage unit 2000b may be implemented by the length adjustment operation of the first leg massage unit 2000a included in the first leg stretching operation described below.

[0370] For ease of explanation, it is assumed below that the length of the second leg massage part 2000b is adjusted while the length of the first leg massage part 2000a is adjusted during the stretching action of the second leg.

[0371] The control unit 1400 can adjust the angle of the second leg massage unit 2000b while maintaining the angle of the first leg massage unit 2000a as in Motion 2C-2.

[0372] For example, the control unit 1400 may determine an adjustment angle for adjusting the angle of the second leg massage 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 massage unit 2000b based on the adjustment angle. The angle adjustment operation of the second leg massage unit 2000b may be performed using the angle adjustment operation of the first leg massage unit 2000a included in the first leg stretching operation described below.

[0373] The control unit 1400 can restore the position of the leg massage unit 2000 after performing the stretching action for the second leg.

[0374] After the leg stretching operation is performed, the control unit 1400 may perform a finishing massage providing operation to stretch the user's legs and buttocks through the leg length adjustment module 2500, the leg angle adjustment module 1350, and the massage module 1110, as in Motion 2D (S3350).

[0375] For example, the control unit 1400 may decrease the length of each leg massage unit by tilting each leg massage unit toward the upper side of the massage device 1000 while the position of the leg massage unit 2000 is restored. As an example, the control unit 1400 may adjust the angle and length of each leg massage unit based on the adjustment length and adjustment angle according to each leg length. As another example, the control unit 1400 may adjust the angle of each leg massage unit to the maximum leg angle and decrease the length of each leg massage unit to the minimum length.

[0376] The control unit 1400 may provide a massage to the user's buttocks through the massage module 1110 while adjusting the angle and length of each leg massage unit. At this time, the massage provided to the buttocks may be a buttock massage in a piriformis muscle stretch mode, such as at least one of acupressure massage, kneading massage, tapping massage, and combination massage.

[0377] The control unit 1400 can terminate the iliopsoas stretch mode after providing the massage.

[0378] The length adjustment operations of the leg massage units included in the first and second leg stretching operations may be performed simultaneously, at different times, or sequentially. For the sake of convenience, it is assumed below that the length adjustment operations of the leg massage units are performed simultaneously.

[0379] In the following, since the first leg stretching action can be applied to the second leg stretching action, only the first leg stretching action will be described for convenience of explanation. For example, the action of the first leg massage unit 2000a included in the first leg stretching action can be applied to the action of the second leg massage unit 2000b included in the second leg stretching action. The action of the second leg massage unit 2000b included in the first leg stretching action can be applied to the action of the first leg massage unit 2000a included in the second leg stretching action.

[0380] FIG. 35 shows a diagram for explaining the stretching operation of the first leg shown in FIG.

[0381] The control unit 1400 can decrease the length of the second leg massage unit 2000b via the leg length adjustment module 2500 and increase the length of the first leg massage unit 2000a (S3331a).

[0382] For example, the control unit 1400 can tilt the leg massage unit 2000 to the maximum in the upward direction of the massage device 1000 based on the maximum leg angle when the massage device 1000 is reclined.

[0383] When the leg massage unit 2000 is tilted to the maximum extent, the control unit 1400 can decrease the length of the second leg massage unit 2000b by a preset length and increase the length of the first leg massage unit 2000a.

[0384] When the length of the second leg massage part 2000b is to be reduced, the control unit 1400 may reduce the length of the second leg massage part 2000b to the shortest minimum length by moving the second leg massage part 2000b to the maximum extent toward the upper end of the second leg massage part 2000b while the second leg air cell 1730 is contracted, but is not limited to this. For example, the control unit 1400 may reduce the length of the second leg massage part 2000b based on the length of the other leg of the user in a manner similar to the method of adjusting the length of the first leg massage part 2000a described below.

[0385] 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 side of the user's leg by expanding (or while expanding) the first leg air cell 1710. The method of expanding the first leg air cell 1710 may be the same as the method of expanding the leg air cells (e.g., first and second sub-calf air cells, first and second sub-foot air cells, etc.) in the operation of S3010 in the piriformis muscle stretch mode.

[0386] For example, the control unit 1400 may determine an 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 may increase the length of the first leg massage unit 2000a by moving the first leg massage unit 2000a downward based on the adjustment length. In this case, the control unit 1400 may move the first leg massage unit 2000a by the adjustment length or to a position corresponding to the first adjustment length.

[0387] The above-mentioned adjustment length determination method may be as follows. For example, a leg length table including a plurality of leg lengths and an adjustment length matched to each leg length may be stored in the memory 1430. The leg length table may be preset according to various objects and stored in the memory 1430. The control unit 1400 may extract an adjustment length matched to any one of the plurality of leg lengths in the leg length table based on the length of one leg of the user. In this case, any one leg length may be the same as or similar to the length of one leg of the user. The control unit 1400 may determine the extracted adjustment length as the adjustment length for adjusting the length of the first leg massage unit 2000a.

[0388] In other words, the control unit 1400 inflates only the first leg air cell 1710 to fix (or while fixing) one of the user's legs to the first leg massage unit 2000a, and adjusts the length of the first leg massage unit 2000a, thereby stretching one of the user's legs.

[0389] In addition, when increasing the length of the first leg massage unit 2000a, the control unit 1400 may operate the first leg massage unit 2610 while the second leg massage unit 2630 is stopped to massage (or while massaging) the foot of one leg and increase the length of the first leg massage unit 2000a. In this case, the driving operation of the first leg massage unit 2610 may be linked with at least one of the expanding operation of the first leg air cell 1710 and the length increasing operation of the first leg massage unit 2000a. The driving operation of the first leg massage unit 2610 may be terminated when the length increasing operation of the first leg massage unit 2000a is completed.

[0390] In other words, the control unit 1400 can stretch one of the user's legs by linking at least one of the driving operation of the first leg massage unit 2610, the expanding operation of the first leg air cell 1710, and the length increasing operation of the first leg massage unit 2000a with the second leg massage unit 2630 stopped and the second leg air cell 1730 contracted.

[0391] The control unit 1400 can adjust the angle of the first leg massage unit 2000a while maintaining the angle of the second leg massage unit 2000b through the leg angle adjustment module 1350 (S3331b).

[0392] 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 toward the downward direction of the massage device 1000 when the length of the first leg massage unit 2000a is increased and the first leg air cell 1710 is expanded.

[0393] 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.

[0394] For example, the control unit 1400 may 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. The control unit 1400 may adjust the angle of the first leg massage unit 2000a by tilting the first leg massage unit 2000a toward the lower side of the massage device 1000 based on the adjustment angle. In this case, the control unit 1400 may tilt the first leg massage unit 2000a by the adjustment angle or to a position corresponding to the adjustment angle.

[0395] The above-mentioned adjustment angle determination method may be similar to the adjustment technique determination method. For example, a leg angle table including a plurality of leg lengths and adjustment angles matched to each leg length may be stored in the memory 1430. The leg angle table may be preset according to various objects and stored in the memory 1430. The control unit 1400 may extract an adjustment angle matched to any one of a plurality of leg lengths pre-stored in the memory 1430 based on the length of one leg of the user. In this case, the one leg length may be the same as or similar to the length of the one leg of the user. The control unit 1400 may determine the extracted adjustment angle as the adjustment angle for adjusting the angle of the first leg massage unit 2000a.

[0396] In other words, the control unit 1400 can adjust the angle of the first leg massage unit 2000a when the length of the first leg massage unit 2000a is increased and the first leg air cell 1710 is inflated, thereby stretching one of the user's legs.

[0397] 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 to this.

[0398] For example, the control unit 1400 can perform at least one of the angle adjustment operation of the first leg massage unit 2000a, the reclining operation of the body massage unit 1100, the expanding operation of the body air cell 1600, and the buttocks massage providing operation in conjunction with each other.

[0399] In the case of reclining the body massage unit 1100, the control unit 1400 may adjust the angle of the first leg massage unit 2000a while reclining 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 may tilt the body massage unit 1100 maximally in the backward direction of the body massage unit 1100 based on the maximum body angle.

[0400] In the case of the body air cell 1600 expansion operation, the control unit 1400 can adjust the angle of the first leg massage unit 2000a after (or while) expanding the body air cell 1600 and moving the user's body. In this case, the control unit 1400 can expand the body air cell 1600 after (or while) increasing the length of the second leg massage unit 2000b.

[0401] As an example, the control unit 1400 may adjust the angle of the first leg massage unit 2000a after (or while) moving the user's body toward the upper side of the massage device 1000 by inflating at least one of the thigh air cells 1617, 1637 and the perineum air cell 1650. At least one of the thigh air cells 1617, 1637 and the perineum air cell 1650 may be inflated while the length of the first leg massage unit 2000a is increasing or has been increased.

[0402] As another example, the control unit 1400 may adjust the angle of the first leg massage unit 2000a after (or while) moving the user's body to one of the two sides of the massage device 1000 by inflating at least one of the back air cells 1613, 1633 and the pelvis air cells 1615, 1635. At least one of the back air cells 1613, 1633 and the pelvis air cells 1615, 1635 may be inflated when the length of the first leg massage unit 2000a is increasing or when the length of the first leg massage unit 2000a has been increased.

[0403] For example, the at least one air cell may include at least one of the second back air cell 1633 and the second pelvis air cell 1635 corresponding to the second leg massage unit 2000b. In other words, the control unit 1400 can inflate at least one of the second back air cell 1633 and the second pelvis air cell 1635 to move the user's body to the side of the massage device 1000 corresponding to the first leg massage unit 2000a.

[0404] As another example, the control unit 1400 can adjust the angle of the second leg massage unit 2000b after (or while) inflating at least one of the back air cells 1613, 1633 and the pelvic air cells 1615, 1635 and inflating at least one of the thigh air cells 1617, 1637 and the perineum air cell 1650 to move the user's body.

[0405] In the case of a buttocks massage providing operation, the control unit 1400 can provide a buttocks massage to the user's buttocks through the massage module 1110 before, after, or while adjusting the angle of the first leg massage unit 2000a.

[0406] Specifically, the control unit 1400 may provide a buttocks massage to the user by projecting the massage module 1110 in a forward direction of the massage module 1110 and applying pressure to the buttocks of the user. At this time, the control unit 1400 may provide a buttocks massage to the user by projecting the massage module 1110 when the angle adjustment of the first leg massage unit 2000a is completed, but is not limited thereto. The buttocks massage may include at least one of a finger pressure massage, a kneading massage, a tapping massage, and a combination massage. The combination massage may be a combination of two or more of a finger pressure massage, a kneading massage, and a tapping massage. At least a part of the buttocks massage action included in the piriformis muscle stretch action may be applied to the buttocks massage providing action described above.

[0407] As described above, the control unit 1400 performs at least one of the following operations in conjunction with the angle adjustment operation of the first leg massage unit 2000a, the reclining operation of the body massage unit 1100, the expansion operation of the body air cell 1600, and the buttocks massage providing operation, but is not limited thereto.

[0408] For example, the control unit 1400 can perform the angle adjustment operation of the second leg massage unit 2000b in conjunction with the angle adjustment operation of the first leg massage unit.

[0409] Specifically, the control unit 1400 can adjust the angle of the first leg massage unit 2000a while adjusting the angle of the second leg massage unit 2000b by tilting the second leg massage unit 2000b in at least one of the upward and downward directions of the massage device 1000. Preferably, the second leg massage unit 2000b can be tilted in the upward direction of the massage device 1000 since the second leg air cell 1710 of the second leg massage unit 2000b is in a contracted state.

[0410] Through this, the control unit 1400 can quickly and accurately extend and relax one of the user's legs (or the iliopsoas muscle of one of the legs), which is the leg to be stretched, thereby preventing unnecessary waste of power to inflate the second leg air cell 1730 and reducing the occurrence of injury to the user's body.

[0411] In addition, the control unit 1400 can stretch and relax the user's leg more effectively than when one of the user's legs is not fixed to the first leg massage unit 2000a and the body air cell 1600 is not inflated, thereby improving the stretching effect.

[0412] In addition, the control unit 1400 can prevent injury to the user and stabilize the user's mind and body (or guide the user) by massaging one of the user's legs to make the user aware that the other leg is the leg to be stretched.

[0413] In addition, the control unit 1400 can more quickly and accurately extend and relax one of the user's legs (or the iliopsoas muscle of one of the legs) than when at least one of the reclining operation of the body massage unit 1100, the expanding operation of the body air cell 1600, and the operation of providing a buttocks massage is not performed.

[0414] In addition, the control unit 1400 can more quickly and accurately extend and relax one of the user's legs (or the iliopsoas muscle of one of the legs) than when the angle adjustment operations of the first and second leg massage units are not performed in conjunction with each other.

[0415] Although the technical concept of the present invention has been described above with reference to the accompanying drawings, this is merely an illustrative description of a preferred embodiment of the present invention and is not intended to limit the present invention. In addition, it is obvious that anyone having ordinary knowledge in the technical field to which the present invention pertains can make various modifications and imitation of the present invention within the scope of the technical concept of the present invention.

[0416] In addition, the configuration and functions of the massage device in this specification may be expanded and applied to various (wearable) healthcare devices that can provide healthcare functions (e.g., kneading / massaging function, biosignal measurement function, etc.). Therefore, the "massage device" in this specification can of course be described as a "(wearable) healthcare device".
