Description

massage device

[0001] The present invention relates to a massage device, and more particularly, to a massage device capable of accurately recognizing changes in the position of a leg massage part according to adjustment of leg length.

[0002] Massage is a medical auxiliary therapy that regulates the body's tone, helps blood circulation, and relieves fatigue by applying various forms of mechanical stimulation to parts of the body, such as kneading, pressing, pulling, tapping, or moving the body.

[0003] The growing demand for massage has led to a surge in demand for massage devices or appliances that offer artificial massage functions, driven by economic and time constraints. In other words, as demand grows for massage to relieve fatigue and stress by loosening tense muscles, a variety of time- and cost-effective massage devices are being released.

[0004] Recently, people's interest in health has increased, and massage devices are evolving from simply providing massage functions to electronic devices that provide various additional functions and / or medical functions.

[0005] Meanwhile, since the leg lengths of users using the massage device are formed in various ways, the leg massage part moves up and down to recognize the position of the legs of the user sitting on the massage device.

[0006] In the past, when recognizing changes in position according to leg length, a Hall sensor using a magnet was used, and the sensor was activated and the position change was recognized as the magnet and the Hall sensor came close to each other. However, in this case, there was a problem in that the upper and lower positions of the leg massage part and the extent to which the leg length increased could not be accurately detected.

[0007] The problem to be solved by the present invention is to provide a massage device that can accurately recognize the position of the leg massage body according to the relative movement length by accurately measuring the relative movement length of the fixed frame part and the movable frame part when the leg massage part is driven.

[0008] However, the problems to be solved by the present invention are not limited to the problems described above, and include problems that can be easily understood by a person having ordinary knowledge in the technical field to which the present invention pertains from this specification and the attached drawings.

[0009] In order to achieve the above-described object, according to one embodiment of the present invention, there is provided a massage device including a leg massage unit having a leg massage body into which a user's leg can be inserted, wherein the leg massage unit includes: a fixed frame unit; a movable frame unit to which the leg massage body is coupled and which can move relative to the fixed frame unit; a driving unit for relatively moving the movable frame unit and the fixed frame unit; and a sensor plate which is formed to extend along a longitudinal central axis and has one side positioned and fixed to the movable frame unit or the fixed frame unit; and a length sensor unit which measures a relative moving length of the movable frame unit and the fixed frame unit is provided.

[0010] According to the present invention, the length sensor unit measures the relative movement length between the movable frame unit and the fixed frame unit to which the leg massage body is connected, thereby having the effect of accurately recognizing changes in leg length.

[0011] In addition, the sensor body senses a light source passing through a plurality of passage holes formed in the sensor plate, and can accurately recognize the position of the movable frame part moving relative to the fixed frame part and the leg massage body connected to the movable frame part, and can accurately adjust the leg length based on the position information.

[0012] In addition, one side of the sensor plate is connected to the fixed frame and fixed in position, and the other side opposite to it is spaced apart from the fixed frame and has a high degree of freedom, which has the effect of preventing damage caused by friction between the sensor body and the sensor plate.

[0013] However, the effects of the present invention are not limited to the effects described above, and include effects that can be easily understood by a person having ordinary skill in the art to which the present invention pertains from this specification and the attached drawings.

[0148] Referring to FIG. 4, the guide portion (2230) can be inserted into the guide insertion portion (2330) formed in the fixed frame portion (2300) to be described later. As the guide portion (2230) moves on the guide insertion portion (2330), the movable frame body (2210) can move relative to the fixed frame portion (2300).

[0149] The guide part (2230) can pass through the guide insertion part (2330) formed in the fixed frame part (2300) and come into surface contact with one surface of the guide insertion part (2330), and the surface contact between the guide part (2230) and the guide insertion part (2330) has the effect of allowing the movable frame body (2210) to move stably on the fixed frame part (2300).

[0150] Referring to FIGS. 4 to 7 and 11, a fixed frame part (2300) according to one embodiment of the present invention has one side that can be hinged, and one side (upper side based on FIG. 4) can be hingedly fixed to a body massage part (1000), specifically, a frame part (1100).

[0151] Referring to FIG. 11, in the present specification, 'hinge-fixed' means that it is hinge-able and can rotate along a preset rotational center axis (AX2), and the rotational center axis (AX2) is fixed in position.

[0152] Referring to FIG. 4 and FIG. 11, a fixed frame part (2300) according to one embodiment of the present invention can be connected to a movable frame part (2200). One side (upper side based on FIG. 4) of the fixed frame part (2300) is hingedly fixed to the body massage part (1000), and the one side can be rotated clockwise or counterclockwise.

[0153] Referring to FIGS. 4 to 6, a hinge shaft (2310) may be formed in the fixed frame portion (2300).

[0154] The hinge shaft (2310) can be formed to extend along a preset rotation center axis (AX2) and can be spanned over the body massage part (1000), specifically the frame part (1100).

[0155] Although not shown in the drawing, a groove may be formed in the frame portion (1100) so that a hinge shaft (2310) formed in the fixed frame portion (2300) can be seated therein.

[0156] Although not shown in the drawing, the frame portion (1100) may be provided with a hinge cover (not shown in the drawing) that covers the hinge shaft (2310) that is seated in the groove portion. Since the hinge cover covers the hinge shaft (2310), there is an effect of stably maintaining the rotational center axis (AX2) of the hinge shaft (2310) formed in the fixed frame portion (2300).

[0157] Referring to FIG. 6, a fixed frame portion (2300) according to one embodiment of the present invention may have a guide insertion portion (2330) formed on one side facing the movable frame portion (2200), specifically the movable frame body (2210). A guide portion (2230) coupled with the movable frame body (2210) may be inserted into the guide insertion portion (2330), and a movement path may be provided to the guide portion (2230).

[0158] Referring to FIGS. 4 and 6, a plurality of guide insertion parts (2330) according to one embodiment of the present invention may be provided to correspond to a plurality of guide parts (2230), and may be arranged on both sides based on the movement center axis (AX1) of the movable frame part (2200) relative to the fixed frame part (2300).

[0159] Since a plurality of guide insertion parts (2330) are provided in the fixed frame part (2300), a plurality of movement paths can be provided to the movable frame part (2200), specifically the guide part (2230), when the movable frame part (2200) moves relative to the fixed frame part (2300), and there is an effect that the movable frame part (2200) can move stably.

[0160] Referring to FIGS. 4, 5, and 11, a driving unit (2400) according to one embodiment of the present invention can move a movable frame unit (2200) and a fixed frame unit (2300) relative to each other. Specifically, the driving unit (2400) can transmit power to the movable frame unit (2200) or the fixed frame unit (2300) to move the movable frame unit (2200) relative to the fixed frame unit (2300) which is hinged and has one side fixed in position.

[0161] Referring to FIGS. 4, 5, and 11, a driving unit (2400) according to one embodiment of the present invention may include a driving source unit (2410), a lead unit (2430), a screw thread (2431), and a block unit (2450).

[0162] Referring to FIG. 4, a driving source unit (2410) according to one embodiment of the present invention generates power by receiving power, and can be coupled to a moving frame unit (2200). However, the present invention is not limited thereto, and various modifications are possible, such as being coupled to a leg massage body (2100) connected to the moving frame unit (2200).

[0163] Referring to FIGS. 4, 5, and 11, a lead portion (2430) according to one embodiment of the present invention is disposed in a moving frame portion (2200) and is rotatable by receiving power from a driving source portion (2410).

[0164] According to one embodiment of the present invention, the lead portion (2430) is formed to extend along a longitudinal central axis, and can rotate clockwise or counterclockwise with the longitudinal central axis as a rotational center axis.

[0165] According to one embodiment of the present invention, the longitudinal central axis of the lead portion (2430) may be formed identically to the movement central axis (AX1) of the movable frame portion (2200) relative to the fixed frame portion (2300). However, this is not limited thereto, and various modifications may be implemented, such as forming the longitudinal central axis (AX1) of the movable frame portion (2200) relative to the fixed frame portion (2300) and being parallel to it.

[0166] Referring to FIGS. 4 and 5, a lead portion (2430) according to one embodiment of the present invention may have screw threads (2431) formed along the outer circumference thereof, and a block portion (2450) to be described later facing the outer circumference of the lead portion (2430) may have screw grooves (not shown) formed along the inner circumference thereof.

[0167] Accordingly, when the lead part (2430) receives power from the driving part (2400) and rotates around the longitudinal center axis as the rotational center axis, the block part (2450) is blocked from rotating and is fixed in position to the fixed frame part (2300), and a screw groove is formed along the inner circumference facing the lead part (2430), so that the lead part (2430) and the block part (2450) can move relative to each other.

[0168] That is, the lead part (2430) is connected by penetrating the block part (2450), and as the lead part (2430) in which the screw thread (2431) is formed rotates, the position is fixed, and the lead part (2430) can move in a straight line along a preset direction (up and down direction based on FIG. 11) inside the block part (2450) in which the screw groove is formed on the inner surface.

[0169] Due to this, the lead part (2430) and the movable frame part (2200) coupled to the lead part (2430) can move relative to the fixed frame part (2300).

[0170] Referring to FIG. 5 and FIG. 11, a block portion (2450) according to one embodiment of the present invention is coupled to a fixed frame portion (2300) and is movable on a lead portion (2430).

[0171] That is, the block portion (2450) can move relative to the lead portion (2430). The block portion (2450) can be connected to the fixed frame portion (2300) so as to surround the lead portion (2430). A screw groove portion can be formed on the inner surface of the block portion (2450) to correspond to the shape of a screw thread (2431) formed along the outer surface of the lead portion (2430). The lead portion (2430) can penetrate the block portion (2450) and be connected to the block portion (2450).

[0172] Referring to FIG. 4 and FIG. 8, the block portion (2450) can be fixedly positioned and connected to the fixed frame portion (2300). As a result, power is transmitted from the driving source portion (2410) to cause the lead portion (2430) to rotate clockwise or counterclockwise. At this time, since the block portion (2450) is fixedly positioned to the fixed frame portion (2300) so that it cannot rotate, the lead portion (2430) moves relative to the block portion (2450).

[0173] That is, as the lead portion (2430) and the block portion (2450) move relative to each other, the movable frame portion (2200) can move relative to the fixed frame portion (2300) along the movable center axis (AX1).

[0174] According to one embodiment of the present invention, the driving unit (2400) receives power generated from the driving source unit (2410) and converts the rotational motion of the lead unit (2430) into linear motion. However, the present invention is not limited thereto, and various modifications are possible, such as transmitting power in a rack-and-pinion gear manner within the technical concept of the moving frame unit (2200) to which the leg massage body (2100) is coupled moving relative to the fixed frame unit (2300).

[0175] Referring to FIGS. 4 to 11, a length sensor unit (2500) according to one embodiment of the present invention is installed in a movable frame unit (2200) and a fixed frame unit (2300), and can measure a relative movement length as the movable frame unit (2200) and the fixed frame unit (2300) move relative to each other.

[0176] In the present invention, 'measuring the relative movement length' means measuring the change in leg length when the moving frame part (2200) to which the leg massage body (2100) that receives the user's leg is coupled moves relative to the fixed frame part (2300) in which the rotation center axis (AX2) is fixedly positioned on one side (upper side in Fig. 11).

[0177] That is, the length from the hinge shaft (2310) formed in the fixed frame part (2300) to the bottom of the leg massage body (2100) where the user's foot is received can be considered as the leg length, and the leg length can change as the fixed frame part (2300) and the movable frame part (2200) to which the leg massage body (2100) is coupled move relative to each other.

[0178] The length sensor unit (2500) according to one embodiment of the present invention can accurately recognize changes in leg length by measuring the relative movement length according to the relative movement of the movable frame unit (2200) and the fixed frame unit (2300).

[0179] In addition, since the change in leg length can be accurately recognized, there is an effect of being able to accurately recognize the position of the user's feet accommodated in the leg massage body (2100) coupled to the moving frame part (2200).

[0180] Referring to FIGS. 4 to 6, a length sensor unit (2500) according to one embodiment of the present invention may include a sensor body (2510), a sensor plate (2530), and a sensor cover (2550).

The sensor body (2510) is positioned on the outside of a sensor plate (2530) to be described later, and can move on the sensor plate (2530).

[0182] Specifically, as the movable frame part (2200) and the fixed frame part (2300) move relative to each other, the sensor body (2510) fixed in position to the movable frame part (2200) can move on the sensor plate (2530) fixed in position to the fixed frame part (2300).

[0183] According to one embodiment of the present invention, the sensor body (2510) can be placed at a preset distance from the sensor plate (2530).

[0184] This has the effect of reducing friction between the sensor body (2510) and the sensor plate (2530) and preventing damage to the sensor body (2510) and the sensor plate (2530) due to friction.

[0185] However, it is not limited to this, and various modifications are possible, such as the sensor body (2510) and the sensor plate (2530) being in surface contact and being able to move relative to each other.

[0186] According to one embodiment of the present invention, the sensor body (2510) is installed in the movable frame part (2200) and is fixed in position, and the sensor plate (2530) is installed in the fixed frame part (2300) and is fixed in position, but is not limited thereto, and various modifications are possible, such as the sensor body (2510) being installed in the fixed frame part (2300) and the sensor plate (2530) being installed in the movable frame part (2200).

[0194] As an optional embodiment, only one light emitting unit (2511) and one light receiving unit may be provided, and the movement length of the sensor plate (2530) may be measured by sensing that the light source emitted from the light emitting unit (2511) is received by the light receiving unit.

[0195] The light source irradiated from the light emitting unit (2511) according to one embodiment of the present invention can be transmitted to the light receiving unit through the passage hole (2533) formed on the sensor plate (2530) to be described later.

[0196] Whether the light source irradiated from the plurality of light-emitting units (2511a, 2511b, 2511c) is transmitted to the plurality of light-receiving units may vary depending on the through hole unit (2533) formed in the sensor plate (2530), and when the light source is received by the light-receiving unit, information about this is transmitted to the control unit (1200), so that the position of the moving frame unit (2200) can be accurately recognized when the moving frame unit (2200) moves relative to the fixed frame unit (2300).

[0197] In addition, accurately recognizing the position of the moving frame unit (2200) means being able to recognize the position of the leg massage body (2100) coupled to the moving frame unit (2200), and accurately measure the change in the leg length of the user accommodated in the leg massage body (2100).

[0198] Referring to FIGS. 4 to 8, a sensor plate (2530) according to one embodiment of the present invention is placed on an irradiation path of a light source irradiated from a sensor body (2510), and a passage hole (2533) may be formed to allow the light source to pass through.

[0201] Referring to FIGS. 4 to 7, a sensor plate (2530) according to one embodiment of the present invention can be coupled to a fixed frame portion (2300). Although not shown in the drawings, the sensor plate (2530) can be positionally fixed to the fixed frame portion (2300) by a fastening member such as a bolt.

[0202] Referring to FIGS. 5 to 7, a sensor plate (2530) according to one embodiment of the present invention is formed to extend along a longitudinal central axis, and one side (upper side as of FIG. 6) can be positioned and fixed to a fixed frame part (2300).

[0203] According to one embodiment of the present invention, a sensor plate (2530) has one side (upper side as shown in FIG. 6) positioned and fixed to a fixed frame part (2300), and the other side (lower side as shown in FIG. 6) opposite to this can be spaced apart from the fixed frame part (2300).

[0204] Accordingly, the sensor plate (2530) can have its position flexibly changed on the other side (lower side as shown in FIG. 6) opposite to the one side (upper side as shown in FIG. 6) that is fixed in position on the fixed frame part (2300) as the sensor body (2510) moves on the sensor plate (2530).

[0205] In addition, since only one side (the upper side as shown in FIG. 6) of the sensor plate (2530) is fixed to the fixed frame part (2300) and the other side has an increased degree of freedom, when the sensor body (2510) moves on the sensor plate (2530) and comes into contact with it, the position of the sensor plate (2530) can be adjusted in response to a change in the position of the sensor body (2510).

[0206] That is, friction between the sensor body (2510) and the sensor plate (2530) can be reduced, and damage to the sensor body (2510) and the sensor plate (2530) due to friction can be prevented.

[0207] Referring to FIGS. 4 to 7, a sensor plate (2530) according to one embodiment of the present invention can be connected to a side portion based on the central portion of the fixed frame portion (2300).

[0208] This has the effect of preventing the sensor plate (2530) from interfering with the relative movement of the drive unit (2400), specifically the lead unit (2430) and the block unit (2450) located in the center of the fixed frame unit (2300).

[0211] In the present invention, the sensor plate (2530) is positionally fixed to the fixed frame portion (2300), and a fastening hole portion (2531) is formed on one side of the sensor plate (2530) so that a fastening member can pass through and be fastened to the fixed frame portion (2300). However, this is not limited to this, and various modifications are possible, such as the sensor plate (2530) is positionally fixed to the movable frame portion (2200), and a fastening hole portion (2531) is formed on one side of the sensor plate (2530) so that a fastening member can pass through and be fastened to the movable frame portion (2200).

[0212] Referring to FIGS. 6 and 7, a sensor plate (2530) according to one embodiment of the present invention has one side (upper side based on FIG. 6) that is fixed to a fixed frame part (2300) and can contact the fixed frame part (2300) at multiple contact points.

[0213] Referring to FIGS. 6 and 7, a sensor plate (2530) according to one embodiment of the present invention is positionally fixed to a fixed frame part (2300) only on one side (the upper side as shown in FIG. 6), and the other side (the lower side as shown in FIG. 6) opposite thereto is spaced apart from the fixed frame part (2300) to increase the degree of freedom, and the one side (the upper side as shown in FIG. 6) of the sensor plate (2530) to be positionally fixed can contact the fixed frame part (2300) at a plurality of contact points.

[0214] That is, a plurality of fastening holes (2531a, 2531b) can be formed on one side (upper side based on FIG. 7) of the sensor plate (2530), and a plurality of fastening members can be fastened to the fixed frame part (2300) by penetrating the plurality of fastening holes (2531a, 2531b), and the sensor plate (2530) can be positionally fixed to the fixed frame part (2300).

[0215] Since a plurality of fastening holes (2531a, 2531b) are formed and one side (upper side as shown in FIG. 7) of the sensor plate (2530) is positionally fixed to the fixed frame part (2300) at a plurality of contact points, the sensor plate (2530) can be prevented from rotating clockwise or counterclockwise on the fixed frame part (2300).

[0216] Referring to FIGS. 6 and 7, a protrusion (2532) may be formed to protrude outward on one side of a sensor plate (2530) that is positioned and fixed to a fixed frame portion (2300). A fastening hole (2531b) is formed in the protrusion (2532), and one side (upper side based on FIG. 7) of the sensor plate (2530) may be brought into contact at a plurality of contact points, and a plurality of fastening members may be fastened to the fixed frame portion (2300) by penetrating the plurality of fastening holes (2531a, 2531b).

[0217] Referring to FIG. 7, a plurality of fastening holes (2531a, 2531b) may be formed in parallel along the width direction of the sensor plate (2530). However, the present invention is not limited thereto, and within the technical concept of preventing the sensor plate (2530) from rotating on the fixed frame (2300), the plurality of fastening holes (2531a, 2531b) may be spaced apart along the length direction of the sensor plate (2530).

[0218] Referring to FIGS. 5 to 7, a sensor plate (2530) according to one embodiment of the present invention may have a passage hole (2533) formed therein so that a light source irradiated from the sensor body (2510) may pass through.

[0219] The sensor plate (2530) passes through the sensor body (2510) and can be placed on the inside of the sensor body (2510), and specifically, can be placed between the light emitting unit (2511) and the light receiving unit provided in the sensor body (2510).

[0220] Since the passage hole (2533) is formed in the sensor plate (2530), the light source irradiated from the light emitting unit (2511) can pass through the passage hole (2533) and be transmitted to the light receiving unit in the area where the passage hole (2533) is formed on the sensor plate (2530).

[0221] When a light source is received from the light receiving unit, information about it can be transmitted to the control unit (1200), and based on the information, it is possible to determine where the sensor body (2510) is located on the sensor plate (2530).

[0222] Looking at this from another perspective, the movable frame part (2200) in which the sensor body (2510) is fixed in position moves relative to the fixed frame part (2300) in which the sensor plate (2530) is fixed in position, and the position of the movable frame part (2200) that has moved relative to the fixed frame part (2300) can be recognized.

[0223] Looking at this from another perspective, a leg massage body (2100) that receives the user's legs is coupled to a movable frame part (2200), and the position of the leg massage body (2100) coupled to the movable frame part (2200) that moves relative to the fixed frame part (2300) can be recognized.

[0224] This has the effect of accurately recognizing changes in leg length by measuring the relative movement length according to the relative movement of the movable frame part (2200) and the fixed frame part (2300).

[0225] In addition, since the change in leg length can be accurately recognized, there is an effect of being able to accurately recognize the position of the user's feet accommodated in the leg massage body (2100) coupled to the moving frame part (2200).

[0226] Referring to FIG. 8, a plurality of through holes (2533) may be formed in a sensor plate (2530) according to one embodiment of the present invention. The plurality of through holes (2533a, 2533b, 2533c) may be arranged along the width direction (left-right direction based on FIG. 8) of the sensor plate (2530).

[0227]

[0228] Referring to FIG. 8, a plurality of passage holes (2533a, 2533b, 2533c) may correspond to a plurality of light-emitting parts (2511a, 2511b, 2511c) and light-receiving parts arranged along the width direction of the sensor body (2510).

[0229] Accordingly, when a light source is irradiated from one of the plurality of light-emitting units (2511a, 2511b, 2511c) to a light-receiving unit facing the light-emitting unit (2511), the light source can be transmitted to the light-receiving unit by passing through the passage hole (2533) located between the light-emitting unit (2511) and the light-receiving unit.

[0230] Referring to FIG. 8, a plurality of passage holes (2533a, 2533b, 2533c) can be arranged along the width direction of the sensor plate (2530).

[0231] Specifically, a plurality of passage holes (2533a, 2533b, 2533c) formed in the sensor plate (2530) can be formed along virtual axes (VL1, VL2, VL3) formed parallel to the longitudinal (up-down direction based on FIG. 8) central axis of the sensor plate (2530).

[0232] A plurality of virtual axes (VL1, VL2, VL3) can be spaced apart from each other in the width direction of the sensor plate (2530) and parallel to each other.

[0233] The through holes (2533a, 2533b, 2533c) formed in the sensor plate (2530) can be formed along at least one of the virtual axes (VL1, VL2, VL3).

[0234] Referring to FIG. 8, a passage hole (2533) according to one embodiment of the present invention can be formed along a virtual axis (VL1, VL2, VL3) formed parallel to the longitudinal central axis of the sensor plate (2530).

[0235] At least one through hole (2533) may be formed on any one of the multiple virtual axes (VL1, VL2, VL3).

[0236] Referring to FIG. 8, a plurality of passage holes (2533b) may be formed along the direction of the virtual axis (VL2) in one of the plurality of virtual axes (VL1, VL2, VL3).

[0237] A plurality of through holes (2533b) formed along one virtual axis (VL2) can be spaced apart at preset intervals along the longitudinal (up-down direction based on FIG. 8) central axis of the sensor plate (2530).

[0238] Referring to FIG. 8, the passage hole (2533) can be formed in only one of the plurality of virtual axes (VL1, VL2, VL3) in a section preset along the length direction of the sensor plate (2530).

[0239] Specifically, in the first section (P1) located at the top of the sensor plate (2530), a passage hole (2533a) may be formed only in the first virtual axis (VL1) among the plurality of virtual axes (VL1, VL2, VL3), and in the third section (P2) located at the bottom of the sensor plate (2530), a passage hole (2533c) may be formed only in the third virtual axis (VL3) among the plurality of virtual axes (VL1, VL2, VL3).

[0240] Referring to FIG. 8, in the section between the first section (P1) and the third section (P2) along the longitudinal direction of the sensor plate (2530), a passage hole (2533b) may be formed only in the second virtual axis (VL2) among the multiple virtual axes (VL1, VL2, VL3).

[0241] A plurality of through holes (2533b) formed along the second virtual axis (VL2) are provided, and the plurality of through holes (2533b) can be spaced apart in a row.

[0242] Accordingly, when the sensor body (2510) moves on the sensor plate (2530), the light source irradiated from the light emitting unit (2511) can pass through the passage hole (2533) formed in the first section (P1), the third section (P2), and the second section formed between the first section (P1) and the third section (P2), and the light source that has selectively passed through is transmitted to the light receiving unit, and there is an effect of being able to accurately recognize the change in position of the moving frame unit (2200) that moves relative to the fixed frame unit (2300).

[0243] Referring to FIG. 8, a plurality of through holes (2533b) can be formed along a second virtual axis (VL2) among a plurality of virtual axes (VL1, VL2, VL3).

[0244] That is, when the sensor body (2510) moves on the sensor plate (2530) between the first section (P1) and the third section (P2), the light source irradiated from the light emitting section (2511b) can be transmitted to the light receiving section multiple times due to the multiple passage holes (2533b).

[0245] The control unit (1200) can receive an electrical signal from the light receiving unit and measure the relative movement length of the moving frame unit (2200) with respect to the fixed frame unit (2300) as it passes through a plurality of passage holes (2533b).

[0246] Referring to FIG. 8, in the first section (P1), a through hole (2533a) is formed only in the first virtual axis (VL1) among the multiple virtual axes (VL1, VL2, VL3), and it can be recognized that this is the initial position of the movable frame part (2200) with respect to the fixed frame part (2300).

[0247] Referring to FIG. 8, in the third section (P2), a through hole (2533c) is formed only in the third virtual axis (VL3) among multiple virtual axes (VL1, VL2, VL3), and it can be recognized that this is the position where the movable frame part (2200) has moved to the maximum with respect to the fixed frame part (2300).

[0248] That is, this has the effect of being able to measure the relative movement length according to the relative movement of the movable frame part (2200) and the fixed frame part (2300).

[0249] In addition, there is an effect of being able to accurately recognize changes in leg length by measuring the relative movement length according to the relative movement of the movable frame part (2200) and the fixed frame part (2300).

[0250] In addition, since the change in leg length can be accurately recognized, there is an effect of being able to accurately recognize the position of the user's feet accommodated in the leg massage body (2100) coupled to the moving frame part (2200).

[0251] Referring to FIGS. 5 to 7, 9, and 11, a sensor cover (2550) according to one embodiment of the present invention covers a sensor body (2510), and an accommodation space capable of accommodating the sensor body (2510) may be formed inside.

[0252] The sensor cover (2550) is fixed in position on the movable frame part (2200) and has the effect of preventing the sensor body (2510) from being damaged by external foreign substances.

[0253] A cover slit (2551) may be formed through the sensor cover (2550) to allow the sensor plate (2530) to pass through.

[0254] Accordingly, the sensor cover (2550) that accommodates the sensor body (2510) is placed on the outside of the sensor plate (2530), and when the movable frame part (2200) moves with respect to the fixed frame part (2300), the sensor body (2510) and the sensor cover (2550) that covers the sensor body (2510) can move along a preset direction (up and down direction based on FIG. 11) on the sensor plate (2530).

[0255] The operating principle and effect of a massage device according to one embodiment of the present invention as described above will be described.

[0256] Referring to FIGS. 1 to 11, a massage device according to one embodiment of the present invention may include a body massage unit (1000), a leg massage unit (2000), and an arm massage unit (3000). A plurality of leg massage units (2000) may be provided, and the user's left and right feet may be accommodated in the plurality of leg massage units (2000), respectively.

[0257] Specifically, the plurality of leg massage units (2000) may each include a leg massage main body (2100), and the left and right feet of the user (10) may be inserted, placed, and received in the plurality of leg massage main bodies (2100).

[0258] Multiple leg massage units (2000) can be driven independently by receiving electrical signals from the control unit (1200).

[0259] A leg massage unit (2000) according to one embodiment of the present invention may include a leg massage body (2100), a movable frame unit (2200), a fixed frame unit (2300), a driving unit (2400), and a length sensor unit (2500). The fixed frame unit (2300) is provided with a hinge shaft (2310), and may be hinge-connected to the body massage unit (1000), specifically, the frame unit (1100), along a rotational center axis (AX2).

[0260] Since the above rotation center axis (AX2) is fixed, the fixed frame part (2300) can rotate clockwise or counterclockwise with respect to the rotation center axis (AX2), but linear movement along the longitudinal center axis (AX1) of the fixed frame part (2300) can be restricted.

[0261] The movable frame part (2200) is connected to the leg massage body (2100) and can move relative to the fixed frame part (2300). The movable frame part (2200) may include a movable frame body (2210) and a guide part (2230).

[0262] According to one embodiment of the present invention, the movable frame body (2210) is connected to the leg massage body (2100), and the guide part (2230) can be coupled to the movable frame body (2210). The guide part (2230) can be inserted into the guide insertion part (2330) formed in the fixed frame part (2300) and can move along the guide insertion part (2330).

[0263] As the guide part (2230) provided in the movable frame part (2200) is inserted into the guide insertion part (2330) formed in the fixed frame part (2300), the movable frame part (2200) can move relative to the fixed frame part (2300) along the movement center axis (AX1).

[0264] As the movable frame part (2200) moves relative to the fixed frame part (2300), the leg massage body (2100) connected to the movable frame part (2200) also moves relative to the fixed frame part (2300), and the leg length of the user (10) can be adjusted.

[0265] That is, as the movable frame part (2200) and the fixed frame part (2300) move relative to each other, the length from the hinge shaft (2310) formed in the fixed frame part (2300) to the bottom of the leg massage body (2100) connected to the movable frame part (2200) can be adjusted.

[0266] Referring to FIGS. 4, 5, and 11, a driving unit (2400) according to one embodiment of the present invention may include a driving source unit (2410), a lead unit (2430), and a block unit (2450), and the lead unit (2430) rotates due to power generated from the driving source unit (2410).

[0267] Referring to FIG. 11, the lead part (2430) is placed on the moving frame part (2200) and can rotate by receiving power from the driving source part (2410).

[0268] According to one embodiment of the present invention, a block portion (2450) is coupled to a fixed frame portion (2300) and can be fixed in position, and is movable on a lead portion (2430).

[0269] The lead part (2430) and the block part (2450) are connected by a screw method, and a screw groove can be formed along the inner circumference of the block part (2450) to correspond to the screw thread (2431) formed along the outer circumference of the lead part (2430).

[0270] Since the block part (2450) is fixed in position to the fixed frame part (2300), when the lead part (2430) receives power from the driving source part (2410) and rotates, the lead part (2430) can move along the movement center axis (AX1) on the block part (2450).

[0271] As a result, the movable frame part (2200) can move relative to the fixed frame part (2300), and the leg length can be adjusted as the leg massage body (2100) coupled to the movable frame part (2200) moves relative to the fixed frame part (2300).

[0272] Referring to FIGS. 4 to 11, the length sensor unit (2500) is installed in the movable frame unit (2200) and the fixed frame unit (2300), and measures the relative movement length as the movable frame unit (2200) and the fixed frame unit (2300) move relative to each other, and may include a sensor body (2510), a sensor plate (2530), and a sensor cover (2550).

[0273] Referring to Fig. 8, a passage hole (2533) is formed in the sensor plate (2530), and a plurality of passage holes (2533) may be provided.

[0274] A plurality of passage holes (2533a, 2533b, 2533c) can be spaced apart from each other along the width direction of the sensor plate (2530), and each passage hole (2533a, 2533b, 2533c) can be formed at least one way along a virtual axis (VL1, VL2, VL3) formed along the longitudinal direction (up-down direction based on FIG. 8) of the sensor plate (2530).

[0275] Referring to FIG. 8, a plurality of passage holes (2533a, 2533b, 2533c) can be formed in only one of a plurality of virtual axes (VL1, VL2, VL3) in a preset section along the length direction of the sensor plate (2530).

[0276] Accordingly, the light source irradiated from the plurality of light-emitting units (2511a, 2511b, 2511c) provided in the sensor body (2510) corresponding to the positions of the plurality of virtual axes (VL1, VL2, VL3) passes through the passage hole (2533) formed along the width direction of the sensor plate (2530) and is transmitted to the light-receiving unit, thereby accurately recognizing the position of the moving frame unit (2200) that has moved relative to the fixed frame unit (2300).

[0277] That is, since the sensor body (2510) is fixed in position to the movable frame part (2200), there is an effect of being able to recognize the position of the movable frame part (2200) that moves relative to the fixed frame part (2300) where the sensor plate (2530) is fixed in position.

[0278] Recognizing the position of the movable frame part (2200) with respect to the fixed frame part (2300) means being able to recognize the position of the leg massage body (2100) coupled to the movable frame part (2200), and being able to recognize the change in the position of the leg massage body (2100) as the movable frame part (2200) moves with respect to the fixed frame part (2300).

[0279] In addition, the change in the length of the user's legs accommodated in the leg massage body (2100) can be accurately recognized.

[0280] In addition, since the change in leg length can be accurately recognized, there is an effect of being able to accurately recognize the position of the user's feet accommodated in the leg massage body (2100) coupled to the moving frame part (2200).

[0281] As an optional embodiment, a passage hole (2533) may be formed along two or more virtual axes among a plurality of virtual axes (VL1, VL2, VL3) in a section preset along the length direction of the sensor plate (2530), and a light receiving unit that receives a light source passing through the passage hole (2533) transmits an electrical signal to the control unit (1200) to recognize the position of the movable frame unit (2200) with respect to the fixed frame unit (2300), and various modifications are possible.

[0282] According to one embodiment of the present invention, a massage device has an effect of accurately recognizing the position of a leg massage body (2100) according to the relative movement length by having a length sensor unit (2500) accurately measure the relative movement length of a fixed frame unit (2300) and a movable frame unit (2200) when the leg massage unit (2000) is driven.

[0283] That is, the sensor body (2510) senses a light source passing through a plurality of passage holes (2533a, 2533b, 2533c) formed in the sensor plate (2530), and the position of the moving frame part (2200) moving relative to the fixed frame part (2300) along the moving center axis (AX1) and the leg massage body (2100) coupled with the moving frame part (2200) can be accurately recognized, and the leg length can be accurately adjusted based on the position information.
