Description

A massage device that can recognize changes in the position of the leg massage part

[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 capable of recognizing a change in the position of a leg massage unit, by accurately recognizing the position of the leg massage unit according to the relative movement length by having a length sensor unit accurately measure the relative movement length of the fixed frame unit and the movable frame unit when the leg massage unit 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, a massage device including a leg massage unit having a leg massage body into which a user's leg can be inserted, the leg massage unit including: 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 length sensor unit installed on the movable frame unit and the fixed frame unit and measuring a relative moving length according to the relative movement of the movable frame unit and the fixed frame unit.

[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 slits formed on the sensor plate, and can accurately recognize the position of the moving frame part moving relative to the fixed frame part and the leg massage body connected to the moving frame part, and can accurately adjust the leg length based on the position information.

[0012] 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.

[0147] Referring to FIG. 8, the term “hinge-fixed” in this specification 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.

[0148] Referring to FIGS. 4 and 8, 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.

[0149] A guide insertion portion (2330) into which a guide portion (2230) can be inserted can be formed on one side of the fixed frame portion (2300) facing the movable frame body (2210).

[0150] Referring to FIG. 4 and FIG. 8, a hinge shaft (2310) may be formed in the fixed frame portion (2300). The hinge shaft (2310) may be formed to extend along a preset rotational center axis (AX2) and may be spanned over the body massage portion (1000), specifically the frame portion (1100).

[0151] 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.

[0152] 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).

[0153] Referring to FIG. 6, a fixed frame part (2300) according to one embodiment of the present invention may have a guide insertion part (2330) formed on one side facing the movable frame part (2200), specifically the movable frame body (2210).

[0154] A guide part (2230) that is coupled to the moving frame body (2210) can be inserted into the guide insertion part (2330), and a moving path can be provided to the guide part (2230).

[0155] Referring to FIG. 6 and FIG. 8, 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) with respect to the fixed frame part (2300).

[0156] 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.

[0157] Referring to FIGS. 4, 5, and 8, a support member (2350) according to one embodiment of the present invention connects both sides of a fixed frame member (2300), and can specifically connect guide insertion members (2330) formed on both sides of the fixed frame member (2300).

[0158] According to one embodiment of the present invention, the support member (2350) may be formed to extend along the longitudinal direction and may be formed in a bar shape. Specifically, the support member (2350) may be formed to extend along the width direction of the fixed frame member (2300).

[0159] The support member (2350) can be formed to extend with a longitudinal central axis that is perpendicular to the longitudinal central axis of the guide insertion member (2330) formed in the fixed frame member (2300).

[0160] Since the support member (2350) connects the guide insertion members (2330) arranged on both sides based on the relative movement center axis (AX1) of the movable frame member (2200) with respect to the fixed frame member (2300), it is possible to prevent the plurality of guide insertion members (2330) from being twisted by external force, and there is an effect of improving the rigidity of the fixed frame member (2300).

[0161] Referring to FIG. 8, a plurality of support members (2350) may be provided, and a plurality of guide insert members (2330) may be connected, and a plurality of support members (2350) may be arranged in parallel along the longitudinal direction (upper and lower direction based on FIG. 8) of the guide insert member (2330).

[0162] Referring to FIGS. 5 and 8, a support member (2350) according to one embodiment of the present invention may be connected to a sensor plate (2530) to be described later. Specifically, a support groove member (2533) may be formed in the shape of a groove member so that the support member (2350) may be placed on the inside of the sensor plate (2530).

[0163] The support part (2350) is positioned on the inside of the support groove part (2533) formed on the sensor plate (2530), and by being combined with the support groove part (2533), there is an effect of improving the bonding strength of the sensor plate (2530) coupled on the fixed frame part (2300).

[0164] In addition, since the support member (2350) is positioned on the inside of the support groove member (2533), there is an effect of preventing interference in the connection path of the support member (2350) connecting a plurality of guide insertion members (2330).

[0165] Referring to FIGS. 4, 5, and 8, 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).

[0166] Referring to FIGS. 4, 5, and 8, 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).

[0167] 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).

[0168] Referring to FIGS. 4, 5, and 8, a lead portion (2430) according to one embodiment of the present invention is disposed on a movable frame portion (2200) and is rotatable by receiving power from a driving source portion (2410). 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.

[0169] 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.

[0170] Referring to FIGS. 4 and 5, a lead portion (2430) according to one embodiment of the present invention may have a screw thread (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 a screw groove formed along the inner circumference thereof.

[0171] 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.

[0172] 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. 8) inside the block part (2450) in which the screw groove is formed on the inner surface.

[0173] 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).

[0174] Referring to FIG. 4 and FIG. 8, 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).

[0175] 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).

[0176] On the inner surface of the block portion (2450), a screw groove portion may be formed to correspond to the shape of a screw thread (2431) formed along the outer surface of the lead portion (2430). The lead portion (2430) may penetrate the block portion (2450) and be connected to the block portion (2450).

[0177] 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).

[0178] 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).

[0179] 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).

[0180] Referring to FIGS. 4 to 8, 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.

[0181] 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. 8).

[0182] 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.

[0183] 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).

[0184] 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).

[0185] Referring to FIGS. 4 to 8, 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).

[0186] Referring to FIG. 6, a sensor body (2510) according to one embodiment of the present invention irradiates a light source and can be positionally fixed on a movable frame part (2200). 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).

[0187] 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).

[0188] According to one embodiment of the present invention, the sensor body (2510) may be arranged at a preset distance from the sensor plate (2530). 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.

[0189] 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.

[0190] 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).

[0195] Referring to FIG. 6, the light emitting unit (2511) is positioned relatively closer to the moving frame unit (2200) than the light receiving unit (2513), but this is not limited to this, and various modifications are possible, such as the light receiving unit (2513) being positioned relatively closer to the moving frame unit (2200) than the light emitting unit (2511).

[0196] According to one embodiment of the present invention, a plurality of light-emitting units (2511) may be provided, and a plurality of light-receiving units (2513) may also be provided corresponding to the plurality of light-emitting units (2511).

[0197] According to one embodiment of the present invention, three light-emitting units (2511) and three light-receiving units (2513) are provided, but this is not limited to the number of units, and various modifications may be implemented, such as providing four or more units.

[0198] As an optional embodiment, only one light emitting unit (2511) and one light receiving unit (2513) 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 (2513).

[0199] The light source irradiated from the light emitting portion (2511) according to one embodiment of the present invention can be transmitted to the light receiving portion (2513) through a slit portion formed on the sensor plate (2530) to be described later.

[0200] Whether the light source irradiated from the plurality of light-emitting units (2511) is transmitted to the plurality of light-receiving units (2513) may vary depending on the slit portion formed in the sensor plate (2530), and when the light source is received by the light-receiving unit (2513), 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).

[0201] 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).

[0202] Referring to FIGS. 4 to 8, a sensor plate (2530) according to one embodiment of the present invention is positioned on the irradiation path of a light source irradiated from the sensor body (2510), and a slit portion may be formed to allow the light source to pass through.

[0203] A sensor plate (2530) according to one embodiment of the present invention may be formed of a plastic material. Specifically, it may be formed of an ABS (Acrylonitrile butadiene styrene) or a polycarbonate (PC) material.

[0204] Referring to FIGS. 5 and 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 drawing, the sensor plate (2530) can be positionally fixed to the fixed frame portion (2300) by a fastening member such as a bolt.

[0205] Referring to FIGS. 4 and 5, 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).

[0206] 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).

[0207] Referring to FIG. 5, a sensor plate (2530) according to one embodiment of the present invention is formed to extend along the longitudinal direction (upper and lower direction based on FIG. 5) and can be positionally fixed to a fixed frame portion (2300).

[0208] Referring to FIG. 5, the sensor plate (2530) can be coupled to the fixed frame portion (2300) at multiple points. Specifically, both ends (upper and lower ends in FIG. 5) along the length direction of the sensor plate (2530) can be coupled to the fixed frame portion (2300).

[0209] Referring to FIG. 5, a contact portion (2535) may be formed to protrude outward at both ends (upper and lower portions based on FIG. 5) of the sensor plate (2530).

[0210] A plurality of contact portions (2535) are provided, and one contact portion (2535a) can be formed on the upper end of the sensor plate (2530) (the upper end as shown in FIG. 5), and another contact portion (2535b) can be formed on the other end of the sensor plate (2530) (the lower end as shown in FIG. 5).

[0211] A fastening hole (drawing symbol not set) may be formed in the contact portion (2535) so that a fastening member (not shown in the drawing) can pass through it, and the fastening member can pass through the fastening hole and be fastened to the fixed frame portion (2300).

[0212] Since a plurality of contact portions (2535a, 2535b) formed at both ends (upper and lower ends in FIG. 5) of the sensor plate (2530) are fixed in position to the fixed frame portion (2300), the position of the sensor plate (2530) where the slit portion is formed does not change, and as the sensor plate (2530) and the sensor body (2510) move relative to each other, there is an effect of being able to accurately measure and recognize the relative movement length of the fixed frame portion (2300) and the moving frame portion (2200).

[0213] Referring to FIGS. 5 to 7, a sensor plate (2530) according to one embodiment of the present invention may have a slit formed therein so that a light source irradiated from a sensor body (2510) may pass therethrough. The sensor plate (2530) may pass through the sensor body (2510) and be disposed on the inside of the sensor body (2510), and specifically, may be disposed between a light emitting portion (2511) and a light receiving portion (2513) provided in the sensor body (2510).

[0214] Since a slit portion is formed on the sensor plate (2530), in the area where the slit portion is formed on the sensor plate (2530), the light source irradiated from the light emitting portion (2511) can pass through the slit portion and be transmitted to the light receiving portion (2513).

[0215] When a light source is received from the light receiving unit (2513), 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).

[0216] 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.

[0217] 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.

[0218] 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).

[0219] 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).

[0220] Referring to FIG. 7, a slit portion formed on a sensor plate (2530) according to one embodiment of the present invention may include a plurality of slits (2532a, 2532b, 2532c). The plurality of slits (2532a, 2532b, 2532c) may be spaced apart from each other along the width direction of the sensor plate (2530).

[0221] Referring to FIG. 6, a plurality of slits (2532) may correspond to a plurality of light-emitting units (2511) and light-receiving units (2513) arranged along the width direction of the sensor body (2510).

[0222] Accordingly, when a light source is irradiated from one of the plurality of light-emitting units (2511) to the light-receiving unit (2513) facing the light-emitting unit (2511), the light source can be transmitted to the light-receiving unit (2513) by passing through the slit (2532) located between the light-emitting unit (2511) and the light-receiving unit (2513).

[0223] Referring to FIG. 7, a plurality of slits (2532) can be arranged along the width direction of the sensor plate (2530).

[0224] Specifically, a plurality of slits (2532) formed on the sensor plate (2530) can be formed along virtual axes (VL1, VL2, VL3) formed parallel to the longitudinal (up-down direction based on FIG. 7) central axis of the sensor plate (2530).

[0225] Multiple 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.

[0226] The slit (2532) formed in the sensor plate (2530) can be formed along any one of the virtual axes (VL1, VL2, VL3).

[0227] Referring to FIG. 7, a slit (2532) provided in a slit section according to one embodiment of the present invention may have an open section (OS) and a closed section (CS) alternately formed along a virtual axis.

[0228] Referring to FIG. 7, a plurality of slits (2532) are provided, and may include a first slit (2532a), a second slit (2532b), and a third slit (2532c).

[0229] Among the plurality of slits (2532a, 2532b, 2532c), the first slit (2532a) may be formed along the first virtual axis (VL1), the second slit (2532b) may be formed along the second virtual axis (VL2), and the third slit (2532c) may be formed along the third virtual axis (VL3).

[0230] The open section (OS) and the closed section (CS) formed in the first slit (2532a), the second slit (2532b), and the third slit (2532c) can be formed with different sections along the longitudinal central axis of the sensor plate (2530).

[0231] Referring to FIG. 7, at least one open section (OS) formed in a plurality of slits (2532a, 2532b, 2532c) can be formed along the width direction of the sensor plate (2530) at a preset point formed along the longitudinal direction (upper and lower direction based on FIG. 7) of the sensor plate (2530).

[0232] Referring to FIG. 7, at the first point (P1), a plurality of open sections (OS), specifically three slits (2532a, 2532b, 2532c), can be formed along the width direction of the sensor plate (2530).

[0233] At the second point (P2), an open section (OS) can be formed only in the first slit (2532a), and at the third point (P3), an open section (OS) can be formed in the first slit (2532a) and the second slit (2532b).

[0234] At the fourth point (P4), an open section (OS) can be formed only at the second slit (2532b), and at the fifth point (P5), an open section (OS) can be formed at the second slit (2532b) and the third slit (2532c).

[0235] At the sixth point (P6), an open section (OS) can be formed only at the third slit (2532c), and at the seventh point (P7), an open section (OS) can be formed at the first slit (2532a) and the third slit (2532c).

[0236] The first point (P1) to the seventh point (P7) refer to the positions of the sensor body (2510) moving on the sensor plate (2530) that is fixed on the fixed frame part (2300) when the fixed frame part (2300) and the movable frame part (2200) move relative to each other.

[0237] That is, a light emitting unit (2511) and a light receiving unit (2513) are arranged facing each slit (2532), and in the open section (OS) of the slit (2532), the light source irradiated from the light emitting unit (2511) can be transmitted to the light receiving unit (2513), and in the closed section (CS) of the slit (2532), the light source irradiated from the light emitting unit (2511) is blocked by the sensor plate (2530) forming the closed section (CS), and therefore cannot be transmitted to the light receiving unit (2513).

[0238] Referring to FIG. 8, the sensor body (2510) moves on the sensor plate (2530) while the movable frame part (2200) moves relative to the fixed frame part (2300), and by detecting the open section (OS) and the closed section (CS) formed in each of the plurality of slits (2532a, 2532b, 2532c), there is an 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).

[0239] 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).

[0240] 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).

[0241] Referring to FIG. 5 and FIG. 7, in a sensor plate (2530) according to one embodiment of the present invention, a support groove (2533) may be formed in the shape of a groove so that a support portion (2350) connecting both sides of a fixed frame portion (2300) may be placed on the inside.

[0242] This can prevent interference between the support part (2350) and the sensor plate (2530) when the sensor plate (2530) and the fixed frame part (2300) are connected.

[0243] Referring to Fig. 7, a support connection part (2534) may be formed to protrude in the support groove part (2533) toward the support part (2350), and the support connection part (2534) may be inserted and fastened to the support part (2350). This has the effect of stably fixing the sensor plate (2530) to the fixed frame part (2300).

[0244] According to one embodiment of the present invention, the sensor plate (2530) and the support portion (2350) are in contact through the support connection portion (2534), but this is not limited thereto, and various modifications are possible, such as the support groove portion (2533) formed on the sensor plate (2530) and the support portion (2350) being spaced apart from each other.

[0245] Referring to FIGS. 4, 5, and 8, 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. The sensor cover (2550) is coupled to a fixed frame portion (2300) and has the effect of preventing damage to the sensor body (2510) from external foreign substances.

[0246] A passage hole (drawing symbol not set) may be formed in the sensor cover (2550) to allow the sensor plate (2530) to pass through.

[0247] 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. 8) on the sensor plate (2530).

[0248] The operating principle and effect of a massage device according to one embodiment of the present invention as described above will be described.

[0249] Referring to FIGS. 1 to 8, 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 a user's left foot and right foot may be accommodated in each of the plurality of leg massage units (2000A, 2000B).

[0250] Specifically, the plurality of leg massage units (2000A, 2000B) may each include a leg massage main body (2100), and the left and right feet of the user (10) may be inserted, placed, and accommodated in the plurality of leg massage main bodies (2100).

[0251] Multiple leg massage units (2000A, 2000B) can be driven independently by receiving electrical signals from the control unit (1200).

[0252] 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).

[0253] 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 movement center axis (AX1) of the fixed frame part (2300) can be restricted.

[0254] 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).

[0255] 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).

[0256] 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).

[0257] 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.

[0258] 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.

[0259] Referring to FIG. 4 and FIG. 8, 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).

[0260] Referring to FIG. 8, the lead part (2430) is coupled to the movable frame part (2200) and rotates by receiving power from the driving source part (2410), and the block part (2450) can be fixed in position to the fixed frame part (2300).

[0261] 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).

[0262] 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).

[0263] 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).

[0264] Referring to FIGS. 4 to 8, 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).

[0265] Referring to FIG. 7, a slit portion is formed in the sensor plate (2530), and the slit portion may include a plurality of slits (2532).

[0266] A plurality of slits (2532) can be spaced apart along the width direction of the sensor plate (2530), and each slit (2532) can have an open section (OS) and a closed section (CS) alternately formed along a virtual axis (VL1, VL2, VL3) formed along the length direction (up-down direction based on FIG. 7) of the sensor plate (2530).

[0267] Through the open section (OS) provided in the slit (2532), the light source irradiated from the sensor body (2510), specifically the light emitting unit (2511), can be transmitted to the light receiving unit (2513) positioned facing the light emitting unit (2511), and the position of the moving frame unit (2200) can be recognized as the moving frame unit (2200) moves relative to the fixed frame unit (2300).

[0268] Referring to FIG. 7, the open sections (OS) and closed sections (CS) of the plurality of slits (2532a, 2532b, 2532c) may be formed differently at a plurality of points (P1 to P7) formed along the longitudinal direction (upper and lower direction based on FIG. 7) of the sensor plate (2530).

[0269] Specifically, the position of the sensor body (2510) moving on the sensor plate (2530) can be recognized depending on whether or not the open sections (OS) formed in the plurality of slits (2532a, 2532b, 2532c) arranged along the width direction (left-right direction based on FIG. 7) of the sensor plate (2530) at a specific point overlap.

[0270] From another perspective, 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.

[0271] 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).

[0272] In addition, the change in the length of the user's legs accommodated in the leg massage body (2100) can be accurately recognized.

[0273] 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).

[0274] Referring to FIG. 7 and FIG. 8, a plurality of contact portions (2535) may be formed protrudingly on one side of the sensor plate (2530), and the contact portions (2535) may be formed protrudingly at both ends (upper and lower ends based on FIG. 7) along the longitudinal direction (upper and lower direction based on FIG. 7) of the sensor plate (2530) and may be connected to the fixed frame portion (2300).

[0275] This has the effect of firmly fixing the sensor plate (2530) to the fixed frame part (2300) and allowing it to be combined.

[0276] 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.

[0277] That is, the sensor body (2510) senses a light source passing through a plurality of slits (2532) formed on 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.

[0278] Hereinafter, the configuration, operating principle, and effect of a massage device according to another embodiment of the present invention will be described.

[0279] Fig. 9 is a rear perspective view illustrating a leg massage unit according to another embodiment of the present invention. Fig. 10 is a perspective view illustrating a sensor plate according to another embodiment of the present invention.

[0280] Referring to FIGS. 1 to 3, 9, and 10, a massage device according to another embodiment of the present invention may include a body massage unit (1000), a leg massage unit (2000`), and an arm massage unit (3000).

[0281] Referring to FIGS. 9 and 10, a massage device according to another embodiment of the present invention has a different configuration of a leg massage unit (2000`), specifically a length sensor unit (2500`), compared to a massage device (100) according to one embodiment of the present invention, and therefore, the following description will focus on the length sensor unit (2500`).

[0282] Referring to FIGS. 9 and 10, a length sensor unit (2500`) according to another embodiment of the present invention is installed in a movable frame unit (2200) and a fixed frame unit (2300), and can measure a relative moving length as the movable frame unit (2200) and the fixed frame unit (2300) move relative to each other.

[0283] The length sensor unit (2500`) can accurately recognize changes in leg length by measuring the relative movement length according to the relative movement of the moving frame unit (2200) and the fixed frame unit (2300).

[0284] 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).

[0285] Referring to FIG. 9 and FIG. 10, the length sensor unit (2500`) may include a sensor body, a sensor plate (2530`), and a sensor cover (2550`).

[0286] The length sensor unit (2500`) according to another embodiment of the present invention has a difference in the configuration of the sensor plate (2530`) compared to the length sensor unit (2500) according to one embodiment of the present invention, so the following description will focus on the sensor plate (2530`).

[0287] Referring to FIGS. 9 and 10, a sensor plate (2530`) according to another embodiment of the present invention is placed on the irradiation path of a light source irradiated from the sensor body, and a slit portion (2532`) may be formed to allow the light source to pass through.

[0288] A sensor plate (2530`) according to another embodiment of the present invention may be formed of a metal material.

[0289] Since the sensor plate (2530`) is formed of a metal material, it can be formed relatively thinner than when formed of a plastic material, and has the effect of reducing friction caused by contact with the sensor body.

[0290] In addition, there is an effect of preventing wear of the sensor plate (2530`) due to friction with the sensor body.

[0291] Referring to FIG. 9, the sensor plate (2530`) can be coupled to the fixed frame part (2300). Although not shown in the drawing, the sensor plate (2530`) can be positionally fixed to the fixed frame part (2300) by a fastening member such as a bolt.

[0292] Referring to Fig. 9, the sensor plate (2530`) can be connected to a side based on the central portion of the fixed frame portion (2300). This has the effect of preventing the sensor plate (2530`) from interfering with the driving portion (2400), specifically the lead portion (2430) and the block portion (2450), which are located in the central portion of the fixed frame portion (2300), when they move relative to each other.

[0293] Referring to FIG. 9, a sensor plate (2530`) according to another embodiment of the present invention is formed to extend along the longitudinal direction (upper and lower direction based on FIG. 9) and can be positionally fixed to a fixed frame portion (2300).

[0294] Referring to FIG. 9, the sensor plate (2530`) can be coupled to the fixed frame part (2300) at multiple points. Specifically, both ends (upper and lower ends in FIG. 9) along the length direction of the sensor plate (2530`) can be coupled to the fixed frame part (2300).

[0295] Referring to Fig. 9, a contact portion (2535`) may be formed to protrude outward at both ends (upper and lower portions based on Fig. 9) of the sensor plate (2530`).

[0296] A plurality of contact portions (2535`) are provided, and one contact portion (2535`a) can be formed on the upper end of the sensor plate (2530`) (the upper end as shown in FIG. 9), and another contact portion (2535`b) can be formed on the other end of the sensor plate (2530`) (the lower end as shown in FIG. 9).

[0297] A fastening hole (drawing symbol not set) may be formed in the contact portion (2535`) so that a fastening member (not shown in the drawing) can pass through it, and the fastening member can pass through the fastening hole and be fastened to the fixed frame portion (2300).

[0298] Since a plurality of contact portions (2535`a, 2535`b) formed at both ends (upper and lower portions in Fig. 9) of the sensor plate (2530`) are fixed in position to the fixed frame portion (2300), the position of the sensor plate (2530`) in which the slit portion (2532`) is formed does not change, and as the sensor plate (2530`) and the sensor body move relative to each other, there is an effect of being able to accurately measure and recognize the relative movement length of the fixed frame portion (2300) and the moving frame portion (2200).

[0299] Referring to FIGS. 9 and 10, a slit portion (2532`) may be formed in the sensor plate (2530`) to allow a light source irradiated from the sensor body to pass through. The sensor plate (2530`) may pass through the sensor body and be placed on the inside of the sensor body, and specifically, may be placed between a light emitting portion and a light receiving portion provided in the sensor body.

[0300] Since the slit portion (2532`) is formed on the sensor plate (2530`), the light source irradiated from the light emitting portion can pass through the slit portion (2532`) and be transmitted to the light receiving portion in the area where the slit portion (2532`) is formed on the sensor plate (2530`).

[0301] 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 is located on the sensor plate (2530`).

[0302] Looking at this from another perspective, the movable frame part (2200) in which the sensor body 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.

[0303] 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.

[0304] 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).

[0305] 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).

[0306] Referring to FIGS. 9 and 10, a slit portion (2532`) formed in a sensor plate (2530`) according to another embodiment of the present invention may have a different width along the longitudinal direction of the sensor plate (2530`).

[0307] A sensor body according to another embodiment of the present invention may include a plurality of light-emitting units and light-receiving units, similar to the sensor body (2510) according to one embodiment of the present invention, and the plurality of light-emitting units and light-receiving units may be arranged along the width direction of the sensor body (left-right direction based on FIG. 10).

[0308] Referring to FIG. 10, the slit portion (2532`) formed in the sensor plate (2530`) has a different width along the longitudinal direction (up-down direction based on FIG. 10) of the sensor plate (2530`), and in the first section (2532`a), the slit portion (2532`) can be formed with a first width (D1) that is relatively wide.

[0309] According to another embodiment of the present invention, the slit portion (2532`) may have a second width (D2) that is relatively narrower than the first width (D1) in the second section (2532`b) connected to the first section (2532`a). In the third section connected to the second section (2532`b), a closed section that blocks the passage of a light source along the width direction of the sensor plate (2530`) may be formed.

[0310] That is, in the first section (2532`a), the light source irradiated from a plurality of light-emitting units passes through the slit section (2532`) and is transmitted to a plurality of light-receiving units, and in the second section (2532`b), the light source irradiated from some of the light-emitting units among the plurality of light-emitting units can be transmitted to a light-receiving unit arranged facing it.

[0311] Additionally, in the third section, since the light source irradiated from the plurality of light-emitting units cannot pass through the sensor plate (2530`) due to the closed section, the light source may not be transmitted to any of the plurality of light-receiving units.

[0312] According to another embodiment of the present invention, the sensor plate (2530`) has a slit section (2532`) through which a light source can pass formed with different widths in sections formed along the movement center axis (AX1) of the movable frame section (2200) relative to the fixed frame section (2300), so that the relative movement length according to the relative movement of the movable frame section (2200) and the fixed frame section (2300) can be measured depending on whether or not the light source is received in each section, thereby accurately recognizing the change in leg length.

[0313] 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).

[0314] Referring to FIG. 10, a support groove (2533`) may be formed in the shape of a groove so that a support portion (2350) connecting both sides of a fixed frame portion (2300) can be placed on the inside of the sensor plate (2530`).

[0315] This can prevent interference between the support part and the sensor plate (2530`) when the sensor plate (2530`) and the fixed frame part (2300) are connected.

[0316] According to another embodiment of the present invention, the length sensor unit (2500`) has a single slit portion (2532`) formed, and the widths are formed differently along the longitudinal direction (up-down direction based on FIG. 10) of the sensor plate (2530`). However, the configuration, operating principle, and effect of the sensor body (2510) and sensor cover (2550) of the length sensor unit (2500) according to one embodiment of the present invention are the same, so detailed descriptions are omitted to the extent that they overlap.

[0317] A massage device according to another embodiment of the present invention has the same configuration, operating principle and effect of the moving frame part (2200), the fixed frame part (2300) and the driving part (2400), except that there is a difference in the length sensor part (2500`) with respect to the configuration of the leg massage part (2000`), so a detailed description thereof will be omitted to the extent that it overlaps therewith.

[0318] Although embodiments of the present invention have been described in more detail with reference to the attached drawings, the present invention is not necessarily limited to these embodiments, and various modifications may be made within the scope of the technical idea of ​​the present invention.

[0319] Accordingly, the embodiments disclosed in the present invention are not intended to limit the technical idea of ​​the present invention but to explain it, and the scope of the technical idea of ​​the present invention is not limited by these embodiments.

[0320] Therefore, it should be understood that the embodiments described above are exemplary in all respects and not limiting.

[0321] The scope of protection of the present invention should be interpreted by the claims, and all technical ideas within the scope equivalent thereto should be interpreted as being included in the scope of the rights of the present invention.
