Description

Technical Field

[0001] This utility model relates to a foot massage device and a massage device including the same, and more specifically, to a foot massage device that realizes foot and ankle movement by dynamically changing the posture of the foot and a massage device including the same. Background Technology

[0002] Massage is a medical adjunctive therapy that uses various forms of mechanical stimulation, such as kneading, pressing, stretching, patting, or physical activity, to regulate the user's biorhythms, improve blood circulation, and relieve fatigue.

[0003] As dietary habits, lifestyles, activity areas, and other aspects of life change, and as attention to health and work-life balance increases, the demand for massage devices or equipment (hereinafter collectively referred to as "massage devices") that provide muscle relaxation, tension relief, fatigue recovery, and stress relief is also increasing.

[0004] Recently, massage devices have gone beyond simply providing massage to the user's body, and have also become electronic devices that offer a variety of additional functions, convenience features, and medical assistance functions.

[0005] However, these functions attached to massage devices may only be functions that improve the convenience of users of massage devices such as interfacing or help them to perform other activities other than massage more easily, and are somewhat unrelated to functions that provide direct stimulation or effects to the user's body, such as exercise or stretching.

[0006] Although a massage device with a function for massaging the feet has been disclosed, it is different only in that the feet are added to the body parts that provide massage, and it is not much different from traditional devices.

[0007] Although a massage device that drives a foot massager that houses the foot has also been disclosed, it is difficult to provide efficient exercise or stretching for the foot and ankle because it can only perform actions such as raising or lowering the foot massager in the up-down direction, considering the range of motion and type of movement of the ankle joint.

[0070] 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.

[0071] According to one embodiment of the present invention, the racks can be arranged facing each other on both sides of the upper frame 1131, and the massage module 1110 can move along the racks.

[0072] 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 Using the Y-axis as a reference, it can refer to the Y-axis direction.

[0073] The massage module 1110 may include gears that mesh with a rack. More specifically, the massage module 1110 may include multiple 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0079] 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 positioned in a manner that connects to the lower base frame 1132b.

[0080] 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 is movable 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.

[0081] 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 unit 1100 to slide.

[0082] 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.

[0083] 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.

[0105] The massage device 1000 may also include an interface portion 1450.

[0106] The interface portion 1450 may be disposed on at least a portion of the massage device 1000. For example, the interface portion 1450 may be disposed on the exterior of the arm massage portion 1200.

[0107] The interface unit 1450 may include an input unit and / or an output unit. The input unit may receive user input and send it to the control unit 1400. The output unit may display information about the massage device 1000. For example, the output unit may output various information such as the processing results of the control unit 1400, the operating information of at least one of the body massage unit 1100, the arm massage unit 1200 and the foot massage device 1300, and information about the massage mode being performed.

[0108] Specifically, the input unit can receive commands from the user regarding the operation control of the massage device 1000. The input unit can be implemented in various ways. For example, the input unit can be located in the body massage unit 1100, or in the foot massage device 1300, but is not limited to these. Additionally, the input unit may include...

[0120] The following is for reference Figures 5 to 11B The specific structure, operation, and function of the foot massage device 3000 according to the embodiment (hereinafter referred to as the "second embodiment") will be described in detail. The foot massage device 3000 dynamically changes the posture of the foot massage part.

[0121] Of course, one or more structures included in the massage device 1000 described above can be combined or selectively applied to the foot massage device 3000 described below, and the foot massage device 3000 described below can be implemented as a massage device.

[0122] Furthermore, some of the terms and / or reference numerals relating to the foot massage device 3000 and its lower structure described in the second embodiment below may differ from the terms and / or reference numerals of the massage device, etc., according to the above embodiments.

[0123] This is a tool necessity for effectively illustrating the embodiments. Therefore, if a technical idea corresponding to the level of a person skilled in the art can be realized, one or more of the structures of the following embodiments can be understood as the same as or equivalent to one or more of the structures described above.

[0124] For example, the foot massage unit 100 described in the second embodiment below may be a structure corresponding to the first foot massage unit 1310 or the second foot massage unit 1330 described in the above embodiments.

[0125] The foot massage device 3000 according to the second embodiment is a device for driving a foot massage unit for accommodating a user's foot. Of course, it can be independently applied to a foot massage unit on one side (right side) (the first foot massage unit 1310 of the above embodiment) and a foot massage unit on the other side (left side) (the second foot massage unit 1330 of the above embodiment). In this regard, in the following description, the first and second foot massage units will no longer be distinguished based on the foot, but will be collectively referred to as foot massage units.

[0126] The terms "upper," "lower," "front," "rear," "vertical," and "horizontal" used in the following description are only used to indicate relative standards for describing embodiments of the present invention, and are not intended to specify a certain direction or position from an absolute standard. Of course, they can vary depending on the position of the object, the position or direction of the view, etc.

[0127] Hereinafter, embodiments of the present invention will be described using the Z-axis direction as the reference direction for up / down or vertical, the Y-axis direction as the reference direction for front / back, and the X-axis direction as the reference direction for left / right. For example, a positive Z-axis direction corresponds to the upward direction, upper side, above, or a direction corresponding to it, while a negative Z-axis direction corresponds to the downward direction, lower side, below, or a direction corresponding to it.

[0128] Figure 5 This is a diagram showing the overall structure of a foot massage device 3000 according to an embodiment of the present invention. Figure 6 This is an exploded perspective view showing the structure of a foot massage device 3000 according to an embodiment of the present invention.

[0129] As shown in the figure, the foot massage device 3000 of this utility model may include one or more of the following: foot massage part 100, drive part 200, cam assembly 300, coupler 400 and base frame 500.

[0130] The foot massage unit 100 includes a receiving space 100S for accommodating the user's feet, such as... Figure 11A and Figure 11B As shown, according to the embodiment, it may include a foot massage module 105 that massages the accommodated foot by using units such as rollers and balls.

[0131] When an additional calf massage section 50 is provided, the foot massage section 100 of this utility model can be configured below the calf massage section 50 to conform to the human body structure.

[0132] According to the embodiment, the calf massage part 50 can be configured to move the leg frame 40 up and down in the vertical direction as a relatively fixed body, and the base frame 500 of this utility model can be configured to be combined with or connected to the leg frame 40.

[0133] The foot massage device 3000 of this utility model utilizes a structurally linked structure to drive the foot massage unit 100 to rotate (hereinafter referred to as "first rotation") while dynamically changing the posture of the foot massage unit 100, so that the movement, stimulation or stretching of the ankle can be fully performed.

[0134] The drive unit 200 of this invention provides a driving force to achieve the "first rotation." According to this invention, the cam assembly 300 utilizes the rotational force of the drive unit 200 to guide the foot massage unit 100 to rotate while changing its horizontal posture. Details of the cam assembly 300 will be described later.

[0135] The drive unit 200 may include: a drive motor 210 that rotates by supplied electricity; and a drive transmission unit 220 that transmits the rotational force of the drive motor 210 to the cam assembly 300.

[0136] The drive unit 200 can be provided in the base frame 500, which functions as a relatively fixed body for the foot massage unit 100 that performs the "first rotation". However, according to the embodiment, it can also be provided in a structure independent of the foot massage unit 100, which is a moving body, such as the leg frame 40.

[0137] In the accompanying drawings, a belt is shown as an example of a drive transmission unit 220 that transmits the rotational force of the drive motor 210 to the cam assembly 300, but other units such as gears can of course also be used.

[0138] According to the implementation, in order to adjust and increase rotational force or torque, a pulley 230 that rotates via a belt 220 as a drive transmission unit can be provided in one or more of the drive motor 210 and the cam assembly 300.

[0139] The coupler 400 is located between the foot massage unit 100 and the base frame 500, which is a relatively fixed body of the foot massage unit 100, and guides the movement of the foot massage unit 100 within a limited range.

[0140] The coupler 400 provides physical support for the foot massage unit 100, enabling the foot massage unit 100 to move by rotating when the cam assembly 300, which is in contact with it, rotates. Synchronized with the rotation of the cam assembly 300, the coupler dynamically changes the posture of the foot massage unit 100 and rotates ("first rotation"), rather than the entire foot massage unit 100 rotating in place. The details of the coupler 400 will be explained later.

[0141] Figure 7 This is a diagram showing the specific structure of a wheel assembly 300 according to an embodiment of the present invention.

[0142] like Figure 7 As shown, the cam assembly 300 of this utility model may include a first rotating shaft 310, a second rotating shaft 320, and a cam component 330.

[0143] The first rotating shaft 310 rotates by the rotational force of the drive unit 200, specifically by the rotational force of the drive motor 210 transmitted via the drive transmission unit 220, and can be located at the center of the cam member 330.

[0144] In order to simply realize the driving force transmission relationship with the drive motor 210, preferably, as shown in the figure, the first rotating shaft 310 is arranged at the lower part of the cam member 330.

[0145] Since the first rotating shaft 310 can be fixedly connected to or formed as a whole with the cam member 330, when the first rotating shaft 310 rotates, the cam member 330 also moves and rotates physically together with the first rotating shaft 310.

[0146] As shown in the figure, the surface portion 330P (hereinafter referred to as the "contact portion") of the cam member 330 that contacts the foot massage portion 100 is formed in an inclined shape.

[0147] Since the foot massage unit 100 is configured to contact the contact portion 330P of the cam member 330, the tilt or posture of the foot massage unit 100 corresponds to the current state characteristics of the contact portion 330P.

[0148] When the cam member 330 rotates, the tilt surface of the contact portion 330P changes dynamically, and the tilt or posture of the foot massage portion 100 changes dynamically according to the tilt surface or tilt of the contact portion 330P.

[0149] The second rotating shaft 320, which is a structure of the cam assembly 300, can be connected to the contact portion 330P of the cam member 330, and has a shape that protrudes toward the foot massage portion 100.

[0150] The second rotating shaft 320 can be accommodated in the foot massage unit 100 or rotatably fitted into the foot massage unit 100 to maintain the positional alignment between the foot massage unit 100 and the cam member 330. For noise reduction, clearance minimization, and physical support stability, the second rotating shaft 320 can be indirectly accommodated in the foot massage unit 100 or rotatably fitted into the foot massage unit 100 through one or more ball bearings B.

[0151] The second rotation axis 320 can be set to tilt at a predetermined angle along the oblique direction so that not only can the positional alignment between the foot massage part 100 and the cam member 330 be maintained, but the posture change of the foot massage part 100 can also be clearly realized. As shown in the figure, it is preferably set to be perpendicular to the contact part 330P.

[0152] To enhance durability and improve manufacturing efficiency, the cam assembly 300 preferably uses a high-rigidity material such as metal to realize the first rotation axis 310 and the second rotation axis 320, and is formed by insert injection molding as an insert.

[0153] When the rotational force of the drive motor 210 is transmitted, the first rotating shaft 310 and the cam member 330 rotate in place with the coaxial center. Conversely, since the second rotating shaft 320 has a shape that extends in a direction perpendicular to the contact portion 330P, it maintains a predetermined angle (preferably a right angle) with the contact portion 330P and achieves a rotational behavior similar to precession.

[0154] Figure 8 This is a diagram showing the specific structure of a coupler 400 according to an embodiment of the present invention.

[0155] As described above, the coupler 400 of this invention provides physical support for the foot massage unit 100, allowing the foot massage unit 100 to move via the rotation of the cam assembly 300. Furthermore, the foot massage unit 100 performs a "first rotation," rather than the entire foot massage unit 100 rotating in place.

[0156] As defined above, "first rotation" refers to the rotational movement of the foot massage unit 100, which dynamically changes the posture and rotates the foot massage unit 100.

[0157] like Figure 8 As shown, a coupler 400 according to an embodiment of the present invention may include a cylinder 410, a rotating rod 420, and a linear rod 430.

[0158] The cylinder 410, which is a structure of the coupler 400, has a shape that extends along the length direction (Z-axis direction based on the attached drawing) and has an internal space 410S. A first engaging portion 411H, such as a hole shape, for engaging the first pin P1 of the lower part of the through-rotating rod 420, may be provided at the upper part of the coupler 400, and a second engaging portion 412H, such as a hole shape, for engaging the second pin P2 of the slot 431 of the through-linear rod 430, may be provided at the lower part of the coupler 400.

[0159] The rotating rod 420, which is a structure of the coupler 400, includes: a spherical connecting part 421 that is rotatably constrained to the foot massage part 100; and a body part 422 that has a shape extending along the length direction (Z-axis direction based on the figure) and is rotatably connected to the cylinder 410 by a first pin P1.

[0160] The main body 422 of the rotating rod 420 can be combined with the connecting part 421 of the rotating rod 420. Of course, according to the embodiment, the main body 422 and the connecting part 421 can be formed as one piece.

[0161] The spherical connecting portion 421 of the rotating rod 420 can be rotatably constrained to the coupler receiving portion 120 (see reference). Figure 9 The coupler receiving portion 120 has a concave shape corresponding to the spherical shape of the connecting portion 421 and is provided in the foot massage portion 100.

[0162] Preferably, a coupler cover 423 is provided with a through hole (see reference) after the connecting portion 421 of the rotating rod 420 is received into the coupler receiving portion 120, having a sphere with a diameter smaller than that of the connecting portion 421. Figure 10 The connecting part 421 is attached to the coupler receiving part 120 in the direction from below to above the body part 422 of the rotating rod 420, so that the connecting part 421 can be constrained to the coupler receiving part 120 without detaching from the outside.

[0163] As shown in the figure, the linear rod 430, which is a structure of the coupler 400, has a slot 431 that extends along the length direction (Z-axis direction based on the figure) and is configured to achieve linear movement in the up and down direction along the internal space 410S of the cylinder 410.

[0164] Since the second pin P2 passes through the slot 431 and engages with the second engagement portion 412H formed in the cylinder 410, the linear rod 430 can remain in place without disengaging from the cylinder 410, and linear movement can be stably achieved by the guidance of the slot 431 of the linear rod 430 and the second pin P2.

[0165] Since the moving body and the stationary body have a relative relationship, the cylinder 410 of the coupler 400 can move linearly in the vertical direction with respect to the linear rod 430, which is a relative stationary body, through the slot 431 of the linear rod 430 and the second pin P2. When the cylinder 410 moves in the vertical direction, the rotating rod 420 connected to the cylinder 410 by the first pin P1 also moves in the vertical direction.

[0166] With the structure described above, the coupler 400 of this invention is configured to perform approximately three compound actions as described below.

[0167] First, the spherical connecting portion 421 is rotatably constrained to the foot massage portion 100, specifically to the coupler receiving portion 120 of the foot massage portion 100. Therefore, the foot massage portion 100 can rotate freely within a limited range along the spherical shape (three-dimensional) of the connecting portion 421, while maintaining the relative positional relationship between the connecting portion 421 and the coupler receiving portion 120, i.e., maintaining the coupler 400 and the foot massage portion 100.

[0168] Second, since the rotating rod 420, which is rotatably coupled to the cylinder 410 via the first pin P1, can rotate with reference to the rotation axis RA (X-axis based on the attached drawing) in the direction in which the first pin P1 is fastened, it can rotate and move in the front-back direction (Y-axis direction based on the attached drawing).

[0169] Finally, when the linear rod 430 of the coupler 400 is fixed to the base frame 500, the cylinder 410 of the coupler 400 moves linearly in the up and down direction by being guided by the slot 431 of the linear rod 430.

[0170] As described above, since the coupler 400 of this invention is configured to perform rotational movement and linear movement in a combined manner, the "first rotation" of the foot massage unit 100, that is, the rotational movement of the foot massage unit 100 that dynamically changes the posture of the foot massage unit 100 and rotates, can be performed more effectively.

[0171] Figure 9 and Figure 10 This is a diagram showing the specific structure of the cam assembly 300 and coupler 400, etc., according to an embodiment of the present invention. Figure 11A and Figure 11B This is a cross-sectional view illustrating the movement relationship of the foot massage unit 100 in one embodiment of the present invention.

[0172] For reference only. Figure 11A and Figure 11BThe foot massage device 3000 is shown in cross-section to more clearly show the action relationship of the foot massage unit 100. It is a diagram showing the combined action of the coupler 400, which is linked to the rotational action of the cam assembly 300 shown in cross-section in the middle part, and the "first rotation" of the foot massage unit 100.

[0173] like Figure 9 As shown, the foot massage part 100 of this utility model may include a first guide 130, which has a downwardly protruding track shape and contacts the contact portion 330P of the cam member 330.

[0174] Of course, the lower part of the foot massage part 100 can be configured to directly contact the cam member 330, but when the first guide 130 with the shape features described above is configured to contact the cam member 330, not only can noise be reduced, but the contact and linkage between the foot massage part 100 and the cam member 330 can also be achieved more stably.

[0175] The accompanying drawings show an embodiment where the wall portions constituting the track shape of the first guide 130 have the same height, but according to the embodiment, the first guide 130 may also have a tilted shape or a wave shape with different heights. When configured as described above, the posture of the foot massage unit 100 during its "first rotation" can be varied in more ways.

[0176] like Figure 9 As shown, the foot massage part 100 of this utility model may include a second guide 140, which has a track shape that protrudes downwards, just like the first guide 130.

[0177] Similar to the first guide 130, the second guide 140 can also guide a more stable linkage between the foot massage part 100 and the cam member 330.

[0178] When the first guide 130 and the second guide 140 are configured to make double contact with the cam member 330 on the inner and outer sides, the contact portion 330P of the cam member 330 and the contact area of ​​the foot massage portion 100 can be extended at different positions, thereby more stably realizing the "first rotation" of the foot massage portion 100 through the rotation of the cam member 330.

[0179] Therefore, the radius of the second guide 140 is smaller than that of the first guide 130, and it is preferably located in the central region of the first guide 130. More preferably, it is located at the same position as the center point of the first guide 130.

[0180] According to the embodiment, a ball bearing B can be arranged in the center of the inner space of the second guide 140, and the second rotating shaft 320 is fitted into the ball bearing B.

[0181] According to this embodiment of the present invention, a composite structure is provided, wherein the second rotation shaft 320 of the cam assembly 300 is supported by a ball bearing B, and the ball bearing B, which is fitted with the second rotation shaft 320, is physically supported by a second guide 140, thereby enabling more stable physical support for the foot massage part 100 based on the cam assembly 330.

[0182] Furthermore, when configured as described above, since the second rotation axis 320 of the cam assembly 300 is physically supported by a ball bearing B or the like, the gap between the foot massage unit 100 and the cam member 330 can be minimized, and the "first rotation" of the foot massage unit 100 can be achieved more stably through the rotation (precession) of the second rotation axis 320.

[0183] Considering the range of motion or area of ​​motion of the ankle joint, in order to avoid putting a strain on the ankle joint, it is preferable to guide a relatively larger movement in front of the foot rather than behind the foot where the ankle joint is located.

[0184] Therefore, preferably, the coupler 400 of the present invention is disposed behind the cam assembly 300 for guiding the "first rotation" of the foot massage unit 100 (in the Y-axis direction based on the drawings).

[0185] A linear rod 430, which is a structure of the coupler 400, can be provided on the base frame 500, which is a relatively fixed body of the foot massage unit 100, so that the coupler 400 can support the physical movement of the foot massage unit 100.

[0186] like Figure 9 As shown, preferably, the linear rod 430 is fixedly coupled to a support frame 510 that is coupled to the base frame 500 and has a downwardly extending shape, so as to ensure sufficient space for the cylinder 410 to move in the vertical direction, with the linear rod 430 as a relatively fixed body.

[0187] like Figure 10 and Figure 11A , Figure 11B As shown, when the drive motor 210 rotates, the rotational force of the drive motor 210 is transmitted to the cam assembly 300 through the drive transmission unit 220, specifically to the first rotation shaft 310 of the cam assembly 300.

[0188] When the rotational force is transmitted to the first rotation axis 310 of the cam assembly 300, the cam member 330 and the second rotation axis 320 rotate, and when the cam member 330 with the inclined contact portion 330P rotates, the rotational movement of the foot massage portion 100 in contact with the contact portion 330P is guided.

[0189] The tilt direction of the contact portion 330P changes dynamically due to the rotation of the cam component 330, so the posture of the foot massage portion 100 changes dynamically. The posture change of the foot massage portion 100 is carried out periodically by the rotation of the cam component 300.

[0190] As described above, since the foot massage unit 100 is physically supported by the coupler 400, the part of the foot massage unit 100 that is physically supported by the coupler 400, that is, the part of the coupler receiving part 120 provided with the connecting part 421 for accommodating the rotating rod 420, is kept in a defined area. Therefore, the foot massage unit 100 can have motion characteristics corresponding to the actual range of motion or form of motion of the ankle joint and perform a "first rotation".
