Description

Technical Field

[0001] This utility model relates to a massage device. Background Technology

[0002] Massage refers to a medical adjunct therapy that involves applying various forms of mechanical stimulation to specific parts of the body, such as kneading, pressing, stretching, patting, or moving a part of the body, to regulate changes in the body, promote blood circulation, and relieve fatigue.

[0003] Due to economic and time constraints, there is an increased demand for massage devices or equipment that provide manual massage functions. Specifically, as the need to relieve stiff muscles and eliminate fatigue or stress through massage increases, various massage devices that offer good time and cost-effectiveness have been introduced.

[0004] Recently, people have been paying more attention to health, and massage devices have evolved from simply providing massage functions to electronic devices that offer a variety of additional and / or medical functions. Therefore, research on methods to effectively control massage devices continues.

[0005] In particular, research activity is increasing on devices and methods for providing massage in an optimized form to each user, as each user may have different areas to massage and different levels of stimulation.

[0006] When short users use traditional massage devices, their feet cannot fully contact the foot massage area, making it difficult to provide a massage to the entire foot. Furthermore, traditional massage devices cannot provide ankle stretching and have a limited range of leg stretching, resulting in less effective massage.

The massage module 1110 can massage at least a part of the user's body while moving along the main frame 1130.

[0116] The main frame 1130 of the body massage unit 1100 may include a rack, and the massage module 1110 may provide mechanical stimulation to various parts of the user's body while moving along the rack. For example, the massage module 1110 may massage the user's back and shoulders, waist, hips, and thighs by patting or kneading at least one of these body parts. The massage module 1110 may include, but is not limited to, at least one of a ball massage unit and a roller massage unit.

[0117] The main frame 1130 is used to form the internal structure of the body massage part 1100, and can be made of metal or plastic materials. For example, the main frame 1130 can be made of iron, alloy, steel, etc., but is not limited to these, and can also be made of various hard materials.

[0118] The audio output module 1120 can be positioned in various locations. For example, the audio output module 1120 may include multiple output units, such as an upper audio output unit positioned above the seat portion that contacts the user, a front audio output unit attached to the front end of the left and right arm massage portions 1200 of the seat portion, and / or a rear audio output unit attached to the rear end of the arm massage portions 1200, etc., but is not limited thereto. In this case, the audio output module 1120 can provide stereo sound such as 5.1 channels, but is not limited thereto.

[0119] The arm massage unit 1200 can be disposed on at least one side of the body massage unit 1100, on one side and the other side. For example, the arm massage unit 1200 may include at least one of the following arm massage units: a first arm massage unit 1201 disposed on one side of the body massage unit 1100 for massaging one side of the user's arm; and a second arm massage unit 1202 disposed on the other side of the body massage unit 1100 for massaging the other side of the user's arm. The first arm massage unit 1201 and the second arm massage unit 1202 may be configured symmetrically to each other. The first arm massage unit 1201 may be disposed on one side of at least one of the seat portion and the backrest portion of the body massage unit 1100. The second arm massage unit 1202 may be disposed on the other side of at least one of the seat portion and the backrest portion of the body massage unit 1100.

[0121] The leg massage device 1300 includes a receiving space for accommodating a user's legs and can provide leg massage to a user by massaging at least a portion of the user's legs. For example, the leg massage device 1300 may include a calf massage section for massaging the user's lower legs and / or a foot massage section for massaging the user's feet.

[0122] The leg massager 1300 can be adjusted in length according to the user's body characteristics. For example, when a tall user uses the massager 1000, the length of the leg massager 1300 needs to be longer because of the longer calves. Conversely, when a short user uses the massager 1000, the length of the leg massager 1300 needs to be shorter because of the shorter calves. Therefore, the leg massager 1300 can provide a leg massage customized to the user's height.

[0123] According to one embodiment of the present invention, a user can control a massage device 1000 using a massage device control device 2000. The massage device control device 2000 can be connected to the massage device 1000 via wired and / or wireless communication.

[0124] The massage device control device 2000 may include at least one of the following user devices: a remote controller, a cellular phone, or a personal digital assistant (PDA), but is not limited thereto, and may include various electronic devices that can be connected to the massage device 1000 via wired or wireless communication.

[0125] Figure 2 This is a diagram illustrating the main frame according to an embodiment of the present invention.

[0126] According to one embodiment of the present invention, the main frame 1130 may include an upper frame 1131 on which a massage module 1110 is provided and a base frame 1132 for supporting the upper frame 1131.

[0127] A rack may be provided along the length of the upper frame 1131. The rack is a component used to guide the massage module 1110 to move up and down, and can be constructed using known racks that include multiple valleys and multiple ridges.

[0128] According to one embodiment of the present invention, the racks can be arranged on both sides of the upper frame 1131 in a relative manner, and the massage module 1110 can move along the racks.

[0129] The rack is formed in the vertical direction, but is not limited thereto. The rack may include racks in the front-back direction and racks in the vertical direction. In this disclosure, the front-back direction may refer to the direction from the massage module 1110 toward the user or the direction from the user toward the massage module 1110, to... Figure 2 The X-axis is the reference point. The Y-axis is perpendicular to the X-axis and can point to the side of the massage module 1110.

[0130] The massage module 1110 may include gears that mesh with a rack. More specifically, the massage module 1110 may include gears that mesh with a rack in the forward-backward direction and a rack in the up-down direction, respectively. The gears are rotated by an actuator disposed in the massage module 1110, thereby allowing the massage module 1110 to move forward, backward, up, or down.

[0131] As the massage module 1110 moves forward, the massage intensity can be increased. Conversely, as the massage module 1110 moves backward, the massage intensity can be decreased.

[0132] Racks can be made of metal or plastic materials. For example, racks can be made of iron, steel, alloys, reinforced plastics, melamine resin, phenolic resin, etc., but are not limited to these.

[0133] The upper frame 1131 can be implemented in various shapes. For example, depending on the shape, the upper frame 1131 can be divided into an S-frame, an L-frame, an S&L-frame, and a double S&L-frame, but is not limited to these.

[0134] An S-frame refers to a frame in which at least a portion of the upper frame 1131 includes a shape curved like an "S". An L-frame refers to a frame in which at least a portion of the upper frame 1131 includes a shape curved like an "L". An S&L frame refers to a frame that includes both a shape curved like an "S" and a shape curved like an "L". A double S&L frame refers to a frame that includes a shape curved like an "L" and two portions of shapes curved like an "S".

[0135] The base frame 1132 refers to the part that supports the upper frame 1131 and is in contact with the ground. The base frame 1132 may include an upper base frame 1132a and a lower base frame 1132b.

[0136] The upper base frame 1132a can support the upper frame 1131, and the lower base frame 1132b can be connected to the ground. In addition, the upper base frame 1132a can be set in a manner that connects to the lower base frame 1132b.

[0137] According to one embodiment of the present invention, the upper base frame 1132a is movable along the lower base frame 1132b. For example, the upper base frame 1132a can slide forward or backward along the lower base frame 1132b. In this case, the upper frame 1131 is connected to the upper base frame 1132a, thereby being able to move as the upper base frame 1132a moves.

[0138] For example, when the upper frame 1132a moves forward, the upper frame 1131 can also move forward together; when the upper frame 1132a moves backward, the upper frame 1131 can also move backward together. This allows the body massage section 1100 to slide.

[0139] To allow movement of the upper base frame 1132a, a moving wheel can be provided at the lower part of the upper base frame 1132a. Additionally, a guide member capable of guiding the moving wheel can be provided at the upper part of the lower base frame 1132b. The moving wheel provided in the upper base frame 1132a moves along the guide member provided in the lower base frame 1132b, thereby allowing the upper base frame 1132a to move forward or backward.

[0140] According to another embodiment of the present invention, the massage device 1000 may not provide a sliding function. In this case, the base frame 1132 may not be separated into an upper frame and a lower frame.

[0141] Figure 3 This is a diagram illustrating the specific structure of a massage control device according to an embodiment of the present invention.

In another embodiment, the guide rod 11360 and the first guide rod 11330 may be formed separately, but they may also be combined with each other. In one embodiment, the guide rod 11360 may be disposed between the first guide rod 11330 and the support frame 11340.

[0208] The guide rod 11360 is configured to selectively insert into the calf massage frame 21310 disposed in the main frame 31300 when the foot massage unit 11300 is raised. Therefore, in one embodiment, the length of the guide rod 11360 may be less than the length of the first guide rod 11330. Figure 13 When the actuator 11310 operates to raise the foot massage unit 11300 or the foot massage frame 11320, the first guide rod 11330 moves along the first track 31320 to the upper part of the first track 31320. Additionally, the guide rod 11360 connected to the first guide rod 11330 can enter the calf massage frame 21310 and move under the guidance of the calf massage frame 21310. This guide rod 11360 makes the movement of the foot massage frame 11320 more stable.

[0209] Figure 14The main frame and calf massage part of the leg massage device according to an embodiment of the present invention are shown. Figure 15 The image shows the calf massage section of a leg massage device according to an embodiment of the present invention, viewed from below. Figure 16 It is along Figure 14 A sectional view along line A1-A1.

[0210] like Figure 14 As shown, the calf massage unit 21300 is movably coupled to the main frame 31300. According to an embodiment of the present invention, the calf massage unit 21300 may include a calf massage frame 21310 and a motor 21320.

[0211] The calf massage frame 21310 can receive moving force from the motor 21320. In one embodiment, the motor 21320 can be mounted on a motor bracket 21312, which is mounted on the calf massage frame 21310. Therefore, when the calf massage frame 21310 moves, the motor 21320 and the like mounted on the motor bracket 21312 move together with the calf massage frame 21310.

[0212] The rotational force of the motor 21320 can be transmitted to the calf massage frame 21310 via the power transmission section. In one embodiment, the calf massage unit 21300 may further include a lead screw support 31330. The motor 21320 can be operatively connected to the lead screw 21330 to move the calf massage frame 21310.

[0213] The lead screw 21330 can be mounted on the motor bracket 21312. The lead screw 21330 can be configured parallel to the shaft 21322 of the motor 21320. In one embodiment, the lead screw 21330 can be connected to the shaft 21322 of the motor 21320 via a belt 21340 to receive rotational force. In one embodiment, a gear 21350 for fastening the belt 21340 can be mounted on the lead screw 21330. The lead screw 21330 can be rotatably supported by a lead screw bracket 31330 formed in the main frame 31300.

[0214] When the shaft 21322 of the motor 21320 rotates, the gear 21350 can rotate via the belt 21340. The rotation of the gear 21350 causes the lead screw 21330 to rotate. The lead screw 21330 can be rotatably supported by the lead screw bracket 31330. The lead screw 21330 operates via the rotation of the shaft 21322 of the motor 21320 in a first direction, thereby allowing the calf massage frame 21310 to rise. Conversely, the lead screw 21330 operates via the rotation of the shaft 21322 of the motor 21320 in a second direction, thereby allowing the calf massage frame 21310 to descend.

[0215] According to an embodiment of the present invention, the calf massage frame 21310 may further include a flange 21314. The flange 21314 is configured to protrude from the calf massage frame 21310. In one embodiment, the flange 21314 may include a curved portion. This shape of the flange 21314 facilitates the attachment of the cover of the calf massage portion 21300. In one embodiment, the flange 21314 may include a through hole 21314a. The through hole 21314a may be formed as an elongated hole. The flange 21314 including such a through hole 21314a facilitates the fastening and removal of the cover of the calf massage portion 21300.

[0216] The calf massage section 21300 can move along the main frame 31300. For example... Figure 15 As shown, in one embodiment, the calf massage unit 21300 may include a second guide rod 21360 configured to move along the main frame 31300.

[0217] In one embodiment, the second guide rod 21360 is movable along a second track 31340 formed in the main frame 31300. The second track 31340 may be configured on the first track 31320. In one example, the second track 31340 may be configured to extend a portion of the first track 31320 along the first track 31320.

[0218] The second guide rod 21360 may include a preset cross-sectional shape. The preset cross-section may be designed to minimize the gap of the calf massage part 21300. In addition, the preset cross-section allows the second guide rod 21360 to move smoothly along the second track 31340.

[0219] like Figure 16 As shown, the second track 31340 may include an insertion slot 31342 into which a second guide rod 21360 can be inserted. The first guide rod 11330 can be inserted into the insertion slot 31342. The insertion slot 31342 is configured to extend along the second track 31340.

[0220] As described above, the guide rod 11360 is configured to insert into the second track 31340 of the calf massage frame 21310 when the foot massage frame 11320 is raised. Therefore, the insertion slot 31342 can be configured to accommodate both the first guide rod 11330 and the second guide rod 21360.

[0221] Figure 17 This is a perspective view of a leg massage device according to an embodiment of the present invention.

[0222] like Figure 17As shown, according to an embodiment of the present invention, the main frame 31300 may include a plate portion 31350. The plate portion 31350 may be configured to surround a first track 31320. As shown in the embodiment, when a pair of first tracks 31320 are included, the plate portion 31350 may be configured to extend between the pair of first tracks 31320. In one embodiment, the plate portion 31350 may be integrally formed with the main frame 31300. In another embodiment, the plate portion 31350 may be formed separately from the main frame 31300, but may also be incorporated into the main frame 31300. The plate portion 31350 may support and position constituent elements such as the lead screw bracket 31330 described above.

[0223] The plate portion 31350 may include a hole 31352. In one embodiment, the hole 31352 may include a curved surface. The hole 31352 may allow components such as wiring and air hoses of the leg massage device 1300 to pass through. For example, when the leg massage device 1300 provides massage via an airbag, an air hose may be connected to the leg massage device 1300.

[0224] According to an embodiment of the present invention, the hole 31352 may be an elongated hole including a short side and a long side longer than the short side. In one embodiment, the elongated hole may be configured such that the long side of the elongated hole is substantially aligned with the vertical direction of the plate portion 31350. In particular, the elongated hole can prevent twisting of wiring or hoses, etc., when the foot massage portion 11300 and the calf massage portion 21300 move vertically.

[0225] According to an embodiment of the present invention, a buffer member 31354 may be disposed around the hole 31352. As a non-limiting example, the buffer member 31354 may be made of silicone or rubber. In one example, the buffer member 31354 may be integrally formed around the hole 31352. In another example, the buffer member 31354 may be attached to the periphery of the hole 31352. The buffer member 31354 can prevent wiring, air hoses, etc., passing through the hole 31352 from being damaged due to repeated contact with the hole 31352. When the calf massage part 21300 rises, the calf massage part 21300 may rise higher than the main frame 31300. At this time, the hole 31352 provides space for the wiring, air hoses, etc., to flow, so that the wiring, air hoses, etc., connected to the calf massage part 21300 rise and move together with the calf massage frame 21310, thereby preventing the wiring, air hoses, etc. from twisting.

[0226] According to an embodiment of the present invention, the sensor unit 1410 may include one or more position sensors. In one embodiment, the position sensor may be disposed on the main frame 31300. For example, the position sensor may be disposed on the plate portion 31350 of the main frame 31300. The position sensor is configured to sense the position of the foot massage unit 11300 or the calf massage unit 21300. The position sensor is configured to transmit the sensed information to the control unit 1400.

[0227] The control unit 1400 is configured to control the drive of the leg massage device 1300. In one embodiment, the control unit 1400 is configured to control the operation of the motor 21320. In another embodiment, the control unit 1400 is configured to control the operation of the actuator 11310.

[0228] Specifically, the control unit 1400 is configured to control the operating time and operating period of the motor 21320 or actuator 11310. When the control unit 1400 receives an operation request from the leg massage device 1300 controlled by the massage device control device 2000, it can adjust the drive of the motor 21320 or actuator 11310. In one embodiment, the control unit 1400 is configured to raise the calf massage unit 21300 first and then the foot massage unit 11300 when the user requests to raise the leg massage unit 1300. Since the calf massage unit 21300 is configured to rise from a preset original position and then fall back to the original position, it is possible to raise the calf massage unit 21300 first in response to the raising request, so that there is no interference between the foot massage unit 11300 and the calf massage unit 21300.

[0229] Furthermore, the control unit 1400 is configured to monitor information sensed by the position sensor. The control unit 1400 can monitor and control the respective positions of the foot massage unit 11300 and the calf massage unit 21300 so that the foot massage unit 11300 and the calf massage unit 21300 do not interfere with each other.

[0230] Figure 18 The driving range of the foot massage section of the leg massage device according to an embodiment of the present invention is shown. Figure 19 The driving range of the calf massage section of the leg massage device according to an embodiment of the present invention is shown.

[0231] like Figure 18 As shown, according to this utility model, the driving range of the foot massage part 11300 can be increased. Figure 18 The central foot massage section 11300 remains in its original position. Figure 18 The left side shows the foot massage unit 11300 in its highest position. Figure 18The right side shows the foot massage unit 11300 in its lowest position. The foot massage unit 11300 can rise Z1 from its original position to its highest position, centered on reference line O, and can also descend Z2 from its original position to its lowest position, centered on reference line O. Z1 and Z2 can vary depending on design conditions; according to an embodiment of this invention, Z1 is 70mm and Z2 is 170mm, achieving a total drive range of 240mm. In conventional leg massage devices, the foot massage unit can only descend, and the drive range is also limited to 170mm, which is more restrictive than that of this invention. That is, the foot massage unit 11300 according to this invention provides an expanded drive range, thus allowing the user to receive a full foot massage regardless of their physical condition.

[0232] Reference Figure 19 According to this invention, the calf massage unit 21300 can be driven independently of the foot massage unit 11300, thereby providing the user with various massage techniques or an expanded massage range. In the illustrated embodiment, the calf massage unit 21300 is configured not to descend (Z3 = 0) with respect to the baseline O, but to rise to a preset height Z4. That is, the calf massage unit 21300 can rise from its original position at the baseline O, beyond the hinge axis 1302, to a height of Z4, and then descend back to its original position at the baseline O. Conventionally, the foot massage unit and the calf massage unit move as a single unit, making it difficult for tall users to receive a calf massage. However, according to this invention, the calf massage unit 21300 can move a preset distance with respect to the baseline O, thus allowing even tall users to receive a calf massage, thereby expanding the massage range.

[0233] The technical concept of this utility model has been described above with reference to the accompanying drawings. However, this is only an exemplary description of the preferred embodiment of this utility model and does not limit the scope of this utility model. Furthermore, those skilled in the art should understand that various modifications and imitations can be made without departing from the technical concept of this utility model.

[0234] Furthermore, the structure and function of the massage device described in this manual can be extended and applied to various (wearable) health care devices that provide health care functions (e.g., massage function, biosignal measurement function, etc.). Therefore, the term "massage device" in this manual can be replaced with "(wearable) health care device" for further explanation.
