For example, the sensor portion 1800 can include a touch sensor, a pressure sensor, an infrared sensor, an LED sensor, a light sensor, a Hall sensor, an electrostatic sensor, etc., but is not limited thereto. The sensor portion 1800 can be used to acquire various information. For example, the sensor portion 1800 can be used to identify a user. That is, information about whether a user is seated, a user's body type, whether a user's body has an abnormality, etc. can be acquired. As another example, the sensor portion 1800 can be used to acquire biological information. That is, fingerprint information, face information, voice information, iris information, weight information, electrocardiogram information, body composition information, etc. can be acquired, but is not limited thereto, and various biological information can be included.

[0107] As an optional embodiment, the massage device 100 can sense a contact area and / or a contact position with a user through the sensor portion 1800. In addition, the massage device 100 can acquire a shoulder position of a user through the sensor portion 1800. The massage device 100 can provide a personalized massage based on the acquired information. For example, when the massage device 100 provides a shoulder massage, the massage device 100 identifies a shoulder position of a user according to information acquired through the sensor portion 1800, and can provide a shoulder massage to a user according to the identification result.

[0108] The leg massage part 2000 can be a structure for massaging the user's legs. The leg massage part 2000 forms a leg accommodation space for accommodating the user's legs. A plurality of leg massage parts 2000 can be provided, for example, the leg massage part 2000 can be composed of a first leg massage part 2000A and a second leg massage part 2000B. The right foot and the left foot of the user 10 can be accommodated in the first leg massage part 2000A and the second leg massage part 2000B, respectively.

[0109] Figure 4 is a diagram for explaining Figure 1 a driving method of the massage device.

[0110] Referring to Figure 4 , the first leg massage part 2000A and the second leg massage part 2000B can be independently driven by receiving an electric signal from the control part 1200. The first leg massage part 2000A and the second leg massage part 2000B are rotatably connected to the frame part 1100. The power generated by the hinge driving part 2800 is transmitted to the connection frame part 2100, and the leg massage part 2000 rotates (or performs a hinge motion) in the clockwise direction and / or the counterclockwise direction with the rotation center axis AX1 provided in advance in the frame part 1100 as a reference, and the leg angle can be adjusted. The hinge driving part 2800A and the hinge driving part 2800B are provided in the first leg massage part 2000A and the second leg massage part 2000B, respectively.

[0111] Therefore, various modified embodiments can be made, in which only any one of the first leg massage part 2000A and the second leg massage part 2000B is rotated with respect to the frame part 1100 and the leg angle is adjusted, or the leg angle is adjusted so that the first leg massage part 2000A and the second leg massage part 2000B form the same angle with respect to the frame part 1100.

[0112] Figure 5 is a partial perspective view of a roller massage device of the present utility model in the massage device of Figure 1 partially shown. Figure 6 is a perspective view of a roller massage device according to an embodiment of the present utility model, in which the roller massage device is composed of two rollers. Figure 7 is a side sectional view of a cross section of a first roller of the roller massage device of Figure 6 .

[0113] Referring to Figures 5 to 7 , the roller massage device according to the present utility model can include a roller 2100, a second roller 2200, a third roller 2300, a motor 2400, a driving transmission part 2500, and a roller support part 2600. However, the roller structure can be composed of only the roller 2100, or further include the second roller 2200 (refer to Figure 6) or can additionally include a third roller 2300 (refer to Figure 5

[0114] The roller massage device according to the present application is provided at a leg massage part 2000 of the massage device 100, and the leg massage part 2000 includes a first leg massage part 2000A that massages one side leg of a user and a second leg massage part 2000B that massages the other side leg of the user. The roller massage device according to the present application can be applied to a foot massage device of the leg massage part 2000. However, it is not limited thereto, and can be applied to a calf massage part or any part of the entire massage device.

[0115] The first leg massage part 2000A and the second leg massage part 2000B are physically separated and driven independently of each other, and the length and angle of the first leg massage part 2000A and the length and angle of the second leg massage part 2000B can be adjusted independently of each other. As described above, the length and angle of the first leg massage part 2000A are adjusted by the first leg angle actuator and the first leg length actuator. The length and angle of the second leg massage part 2000B are adjusted by the second leg angle actuator and the second leg length actuator.

[0116] Referring to Figure 6 and Figure 7 , first, an embodiment in which the roller massage device includes a roller 2100 and a second roller 2200 will be described. Here, the second roller 2200 can be replaced with any other driving transmission part, such as a gear engagement structure.

[0117] The roller 2100 has a roller shaft 2120 and massage protrusions 2110 are formed on the outer circumferential surface of the roller 2100. The roller 2100 has an inner space having an opening part on one side. The inner space of the roller 2100 is designed to be able to at least partially accommodate a motor 2400. The motor 2400 can be inserted into the inner space of the roller 2100 through the opening part of the roller 2100. The motor 2400 is provided to allow the roller 2100 to rotate. The roller 2100 can be a structure in which a roller reinforcing pipe 2130 is reinforced toward the motor 2400 side in the main body.

[0118] The massage protrusions 2110 of the roller 2100 are formed in a specific pattern, thereby providing various pressures and stimuli to a user when a foot is massaged, and thus helping to recover fatigue and improve circulation. The roller shaft 2120 extends to the opposite side of the motor 2400 (the opposite side of the opening part of the roller 2100), that is, the other side of the roller 2100. The roller shaft 2120 serves as a rotation reference shaft of the roller and indirectly receives a driving force of the motor 2400 through a driving transmission part 2500. The roller 2100 is supported by a roller support part 2600 in a rotatable manner.

[0119] ​The second roller 2200 is configured in parallel with the roller 2100. The second roller 2200 is designed to be configured in parallel and adjacent to the roller 2100, so that it is possible to simultaneously massage different parts of the foot from each other. The two rollers interact to maximize the pressure dispersion and massage effect of the foot. A plurality of massage protrusions 2210 are formed on the outer peripheral surface of the second roller 2200. Since the massage protrusions of the roller 2100 are more protruded than the massage protrusions 2210 of the second roller 2200, it is possible to massage according to the curvature of the foot. The second roller 2200 is rotated by receiving the driving force of the motor 2400 through the driving transmission part 2500. The second roller 2200 has a second roller shaft 2220 that is rotated by the first driving transmission part 2500A and transmits the driving force to the second driving transmission part 2500B. The second roller shaft 2220 penetrates the second roller 2200 in the length direction or is installed at both ends of the second roller 2200.

[0120] The motor 2400 has a decelerator, for example, inserted into the inner space of the roller 2100 through the opening part. The motor 2400 can be at least partially disposed inside the roller 2100. The motor 2400 can be inserted and configured inside the roller 2100, for example, the motor 2400 is installed in the motor installation bracket 2420 configured at one side of the roller 2100, and can be extended to be inserted into the roller 2100.

[0121] The motor 2400 is used to drive the roller 2100, and is at least partially inserted into the hollow portion of the roller 2100. The motor 2400 is designed to float in the inner space of the roller 2100 to avoid direct contact with the roller 2100. The motor 2400 is inserted in such a way that its outer peripheral surface is spaced apart from the inner peripheral surface of the roller 2100, so that in the inner portion of the roller 2100, an empty space is formed between the roller 2100 and the motor 2400. Therefore, the roller 2100 can be relatively rotated with respect to the motor 2400 without a support structure between the inner peripheral surface of the motor 2400 and the roller 2100.

[0122] Therefore, since there is no bearing between the motor 2400 and the inner peripheral surface of the roller 2100, for example, the motor 2400 can be increased with respect to the inner diameter of the roller 2100. As the size of the motor 2400 increases, the output can be further increased. The motor 2400 has a motor rotating shaft 2410 extending in the length direction of the roller 2100. The motor rotating shaft 2410 extends to the outside of the opening part of the roller 2100. The motor rotating shaft 2410 is directly connected to the driving transmission part 2500. The roller shaft 2120 extends to one side of the roller 2100, and the motor rotating shaft 2410 extends to the opposite side of the roller shaft 2120.

[0123] According to the present application, the motor 2400, which is the core driving source of the roller massage device, can be disposed inside the roller 2100 to save space. In particular, to solve the problem of space limitation of the leg massage part 2000, the space utilization is improved by disposing the motor 2400 inside the roller 2100.

[0124] In addition, a separate bearing is not required between the motor 2400 and the roller 2100, so the output can be increased by increasing the size of the motor. In addition, to reduce the risk of damage to the rotating shaft 2410 of the motor due to high load that can occur when the massage chair is used, the motor 2400 and the roller shaft 2120 are not directly connected. Instead, power is transmitted to the roller shaft 2120 through a detour path. Therefore, the motor 2400 does not directly bear the load during use, thereby greatly improving the durability of the device.

[0125] The drive transmission part 2500 transmits the driving force of the motor 2400 to the roller 2100. One side of the drive transmission part 2500 is connected to the rotating shaft 2410 of the motor and the other side is connected to the roller shaft 2120. The drive transmission part 2500 includes a first drive transmission part 2500A disposed on one side of the roller 2100 and a second drive transmission part 2500B disposed on the other side of the roller 2100. The drive transmission part 2500 receives the driving force of the motor 2400 and transmits it to the second roller 2200 and the roller 2100 in sequence. The first drive transmission part 2500A rotates the second roller 2200 by transmitting the driving force of the motor 2400 to the second roller shaft 2220, and the second drive transmission part 2500B rotates the roller 2100 by transmitting the rotational force of the second roller 2200 to the roller shaft 2120. Thus, the roller can perform a foot massage function while rotating.

[0126] The first drive transmission part 2500A includes a first-1 pulley 2510 coupled to the rotating shaft of the motor 2400 and a second-1 pulley 2540 connected to the first-1 pulley 2510 by a belt. The second drive transmission part 2500B includes a second-2 pulley 2550 connected to the second-1 pulley 2540 by a shaft (shaft connection) and a first-2 pulley 2520 coupled to the roller shaft 2120 and connected to the second-2 pulley 2550 by a belt. The above-mentioned shaft connection can be made by the second roller shaft 2220, but is not limited thereto. It can also be formed by an arbitrary connection structure such as a gear without a separate shaft. Power is transmitted from the motor 2400 to the first-1 pulley 2510, the second-1 pulley 2540, the second-2 pulley 2550, and the first-2 pulley 2520 in sequence. The above-mentioned pulleys are connected by a belt P.

[0127] The 1-1 pulley 2510 is directly coupled to the rotating shaft 2410 of the motor and serves to receive the first driving force from the motor 2400 to transmit it to the next step of the driving transmission part 2500. The 1-1 pulley 2510 directly transmits the driving force to the 2-1 pulley 2540. The 2-1 pulley 2540 is connected with the 1-1 pulley 2510 by the belt P and is coupled to one side of the second roller shaft 2220. The 2-1 pulley 2540 rotates the second roller 2200 by transmitting the driving force received from the 1-1 pulley 2510 to the second roller shaft 2220.

[0128] The 2-2 pulley 2550 is coupled to the other side of the second roller shaft 2220 and rotates by receiving the rotational force of the second roller shaft 2220. The 2-2 pulley 2550 is connected with the 1-2 pulley 2520 by the belt P. The 2-2 pulley 2550 receives the driving force transmitted from the second roller shaft 2220 to rotate the roller 2100. Accordingly, both the roller 2100 and the second roller 2200 are effectively rotated by the driving force of the motor 2400.

[0129] Figure 8 FIG. 1 is a perspective view showing a roller massage device according to an embodiment of the present application. Figure 9 FIG. 2 is a sectional view showing a first roller of the roller massage device of FIG. 1. Figure 8 FIG. 3 is a partial perspective view showing a first roller of the roller massage device of FIG. 1. Figure 10 FIG. 4 is a sectional view showing a first roller of the roller massage device of FIG. 1. Figure 8 FIG. 5 is a side sectional view showing a first roller of the roller massage device of FIG. 1.

[0130] Referring to FIG. 6, Figures 8 to 10 , an embodiment of the roller massage device including not only the roller 2100 and the second roller 2200 but also a third roller 2300 is explained. Here, the second roller 2200 and the third roller 2300 can be replaced with any other driving transmission part, for example, a gear engagement structure.

[0131] Referring to FIG. 7, Figures 8 to 10The roller massage device according to an embodiment of the present invention further includes a third roller 2300 having a third roller shaft 2310, wherein the third roller 2300 is disposed on the opposite side of the second roller 2200 such that the roller 2100 is located between the second roller 2200 and the third roller 2300. The third roller shaft 2310 extends through the third roller 2300 along its length or is mounted on both sides of the third roller 2300. The drive transmission unit 2500 further includes a third drive transmission unit 2500C connected on one side to the roller shaft 2120 and on the other side to the third roller shaft 2310. The third drive transmission unit 2500C includes: first-third pulleys 2530, which are coupled to the side of the first-second pulleys 2520; and a third pulley 2560, which is coupled to the other side of the third roller shaft 2310 and connected to the first-third pulleys 2530 via a belt P.

[0132] At this time, power is transmitted from motor 2400 to pulleys 2510 (first-first), 2540 (second-first), 2550 (second-second), 2520 (first-second), 2530 (first-third), and 2560 (third). Through this structure, the third roller 2300 can effectively receive the driving force from motor 2400 and rotate.

[0133] Figure 11A It is shown Figure 8 A perspective view of the roller support section of the roller massage device. Figure 11B This is a perspective view showing the base plate and support module in the roller support section. Figure 12 This is a perspective view showing the bearing connection structure of the first embodiment of the roller shaft support portion in the roller massage device of this utility model.

[0134] Reference Figure 11A and Figure 11B The roller support 2600 supports the rollers 2100, 2200, and 2300 in a rotatable manner. The roller support 2600 includes a base plate 2610, roller shaft supports 2620 and 2620', and a support module 2630. The base plate 2610 has a flat plate shape that supports the rollers 2100, 2200, 2300, and other components within the roller massage device. The base plate 2610 has a through-hole 2611 formed on the underside of the rollers 2100. The through-hole 2611 provides space to prevent collisions between the massage protrusions 2110 and the base plate 2610.

[0135] Reference Figure 12The roller shaft support part 2620 is provided on the bottom plate 2610 and shaft supports the roller shaft 2120. Other roller shaft support parts 2620' are provided in plurality and shaft support the second roller shaft 2220 and the third roller shaft 2310. The roller shaft support part 2620 includes a first hollow part 2621 (refer to Figure 7 ) through which the roller shaft 2120 penetrates. A bearing 2622 that supports the roller shaft 2120 in such a manner that the roller shaft 2120 can rotate is inserted in the first hollow part 2621. The bearing 2622 can be made of a POM bearing.

[0136] Referring again to Figure 11A and Figure 11B , the support module 2630 is combined and supported in the bottom plate 2610 combined with the leg massage part frame, and provides a support force that can withstand a load exerted by the feet of a user seated on the massage chair against the roller 2100.

[0137] The support module 2630 can be provided in plurality to support the roller 2100 at the penetration part 2611, and each support module 2630 can include a support bracket 2631 and at least one wheel 2632. The at least one wheel 2632 is provided on the lower side of the roller 2100 and supports the roller 2100 while being in contact with the outer peripheral surface of the roller 2100 and performing a rolling motion. The wheel 2632 is shaft-fixed to the support bracket 2631 fixed on the bottom plate 2610. The wheel 2632 is provided on both sides in the width direction of the support bracket 2631, and the roller 2100 can be provided on the wheels 2632 on both sides in such a manner that the roller 2100 is in contact with the wheels 2632 on both sides.

[0138] The at least one wheel 2632 includes at least one first wheel 2632a (refer to Figure 10 ) that supports the roller 2100 on the opposite side of the roller shaft 2120. The roller shaft 2120 of the roller 2100 is supported by the roller shaft support part 2620 on one side of the roller 2100, and the opposite side of the roller 2100 is supported by the first wheel 2632a. Accordingly, the roller 2100 can be uniformly supported by the first wheel 2632a without the need to provide a separate shaft support bearing or bushing on the opposite side of the roller 2100. Alternatively, the at least one wheel 2632 can include at least one second wheel 2632b that supports the roller 2100 on the side of the roller shaft 2120. However, this is not an essential structure, and it serves to assist the first wheel 2632a.

[0139] The support bracket 2631 is disposed at both sides of the through portion 2611 of the bottom plate 2610 in the length direction of the roller 2100, and passes through the through portion 2611 in the width direction of the roller 2100, respectively, and both ends are fixed to the bottom plate 2610. The support bracket 2631 can be coupled to a plurality of wheels 2632 in the shaft, and the plurality of wheels 2632 can be arranged in the support bracket 2631 in the width direction of the roller 2100. The wheel 2632 can be formed of a bearing wheel in which a bearing is internally embedded to minimize friction with the shaft.

[0140] Each of the wheels 2632 disposed in the support bracket 2631 is in contact with the outer circumferential surface of the roller 2100 to support the roller 2100 while performing a rolling motion, and is disposed not to be in contact with other support surfaces such as the ground. Accordingly, the load applied from the roller 2100 to the wheel 2632 is supported by the support bracket 2631 in the leg massage part frame to which the bottom plate 2610 is coupled.

[0141] Two wheels 2632 are disposed at both sides in the width direction of the support bracket 2631. Accordingly, the roller 2100 is disposed in contact with the wheels 2632 at both sides in such a manner as to be supported by the wheels 2632 at both sides. The distance from the center of the roller 2100 to the center of each of the wheels 2632 can be designed to be the same as the distance between the centers of the wheels 2632 at both sides. Thereby, the center of the roller 2100 and the centers of the wheels 2632 at both sides form a truss structure, such as an equilateral triangle arrangement. Thereby, the load generated by the roller 2100 can be effectively supported by the wheels 2632.

[0142] The roller support part 2600 according to the present application effectively disperses the load applied from the user's foot, which improves the overall stability of the device. In particular, the wheels 2632 in the support module 2630 support the roller 2100 while being in contact with the outer circumferential surface of the roller 2100 and performing a rolling motion. This structure effectively supports the load applied to the roller, and in addition, the load applied from the roller 2100 to the wheel 2632 is supported by the support bracket 2631 in the leg massage part frame to which the bottom plate 2610 is coupled, so that the stability of the device can be further strengthened.

[0143] Figure 13 FIG. 7 is a perspective view showing a second embodiment of a roller shaft support part in a roller massage device according to the present application. Figures 14A to 14D FIG. 8 is a perspective view showing the second embodiment of the roller shaft support part from a plurality of sides. Figure 13 FIG. 9 is a perspective view of a bearing coupling structure of the roller shaft support part.

[0144] Referring to Figures 14A to 14D and Figure 12 the second embodiment of the roller shaft support part 2620 described with reference to ​The first embodiment of the roller shaft support portion described above can have a disadvantage. According to the first embodiment of the roller shaft support portion, the bearing 2622 can be composed of a POM bearing, but in this case, the first roller shaft of the roller 2100 can have a problem of wobbling. However, the second embodiment of the roller shaft support portion 2620 solves this problem by forming the roller shaft support portion 2620 as a clamp 2700.

[0145] Referring to the drawings, the roller shaft support portion 2620 is formed of a clamp 2700. A second hollow portion 2711 in which the bearing 2622 is inserted is formed in an upper body 2710 of the clamp 2700 forming the roller shaft support portion 2620. The roller shaft 2120 is pressed into the bearing 2622 and is rotatably supported on the bearing 2622. The roller shaft 2120 penetrates the bearing 2622 and extends. The second hollow portion 2711 fixes the bearing 2622 in the correct position and ensures stable rotation by limiting the movement of the bearing 2622. Two wing portions 2721 are formed in a lower body 2720 of the clamp 2700. The clamp 2700 is fixed to the bottom plate 2610 at the two wing portions 2721 by fastening members.

[0146] The roller support portion 2600 further includes a disc-shaped power transmission disc 2640 inserted into the other face of the roller 2100. The power transmission disc 2640 is installed on the side of the roller 2100 on the roller shaft 2120 side. One end portion of the roller shaft 2120 is inserted into and fixed to the power transmission disc 2640. The one end portion of the roller shaft 2120 is inserted into a third hollow portion 2650 formed in the power transmission disc 2640. Accordingly, the rotation of the roller shaft 2120 is transmitted to the roller 2100. In addition, the outer peripheral surface of the power transmission disc 2640 is fastened to the roller 2100 by a bolt Q. This design ensures a firm connection between the power transmission disc 2640 and the roller 2100.

[0147] The scope of protection of the present invention is not limited to the recitation and description of the embodiments explicitly described above. In addition, it is again stated that the scope of protection of the present invention cannot be limited due to changes or substitutions obvious in the technical field to which the present invention belongs.
