Description

Technical Field

[0001] The utility model relates to a massage device, and more particularly to a massage device capable of accurately identifying position changes of a leg massage part adjusted by leg length. Background Art

[0002] Massage refers to a medical auxiliary therapy that adjusts the body changes of the massage recipient, helps blood circulation and relieves fatigue of the massage recipient by applying various forms of mechanical stimulation to the body parts of the massage recipient, such as kneading, pressing, stretching, patting or body movements.

[0003] Due to economic and time constraints, there is an increasing demand for massage devices or apparatuses that provide manual massage functions. That is, as the demand for relieving stiff muscles and relieving fatigue or stress through massage increases, various massage devices with good time and cost effectiveness have been introduced.

[0004] Recently, people's concern for health has been increasing, and massage devices have evolved from simply providing a massage function to electronic devices providing various additional functions and / or medical functions.

[0005] On the other hand, since the lengths of the legs of the user who uses the massage device are formed differently, when recognizing the position of the legs of the user sitting on the massage device, the leg massage part moves in the up and down direction and recognizes the position.

[0006] Conventionally, a Hall sensor utilizing a magnet is used to identify position changes according to leg length. When the magnet and the Hall sensor are close to each other, the sensor operates and identifies the position change. However, in this case, there is a problem in that it is impossible to accurately detect the upper and lower positions of the leg massage part and the extent of leg length stretch.

[0192] The support portion 2350 may have a longitudinal central axis perpendicular to a longitudinal central axis of the guide insertion portion 2330 formed on the fixing frame portion 2300 and may be extended.

[0193] Since the support portion 2350 is connected to the guide insertion portions 2330 respectively arranged on both sides based on the moving center axis AX1 of the movable frame portion 2200 relative to the fixed frame portion 2300, it can prevent the multiple guide insertion portions 2330 from being twisted due to external force and can improve the rigidity of the fixed frame portion 2300.

[0194] Reference Figure 8 The support portion 2350 may be provided with a plurality of guide inserting portions 2330, and the plurality of support portions 2350 may be provided along the length direction of the guide inserting portion 2330 (in Figure 8 As a reference, they are arranged in parallel.

[0195] Reference Figure 5 and Figure 8 The support portion 2350 according to an embodiment of the present invention may be connected to the sensor board 2530 described later. Specifically, the sensor board 2530 may have a support groove 2533 formed in a groove shape so that the support portion 2350 may be disposed inside.

[0196] Since the support portion 2350 is disposed inside the support groove portion 2533 formed in the sensor board 2530 and coupled to the support groove portion 2533 , it is possible to improve the coupling force of the sensor board 2530 coupled to the fixing frame portion 2300 .

[0197] In addition, since the support portion 2350 is disposed inside the support groove portion 2533 , it is possible to prevent a connection path of the support portion 2350 connecting the plurality of guide inserting portions 2330 from being disturbed.

[0198] Reference Figure 4 、 Figure 5 and Figure 8 According to an embodiment of the present invention, the driving unit 2400 can move the movable frame unit 2200 and the 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, thereby causing the movable frame unit 2200 to move relative to the fixed frame unit 2300.

[0199] Reference Figure 4、 Figure 5 and Figure 8 According to an embodiment of the present invention, the driving portion 2400 may include a driving source portion 2410 , a guiding portion 2430 , a thread 2431 and a block portion 2450 .

[0200] Reference Figure 4 According to an embodiment of the present invention, the driving source portion 2410 generates power by receiving power and can be combined with the moving frame portion 2200. However, the present invention is not limited thereto and can be implemented in various modifications, for example, combined with the leg massage body 2100 connected to the moving frame portion 2200.

[0201] Reference Figure 4 、 Figure 5 and Figure 8 According to an embodiment of the present invention, the guide portion 2430 is provided on the movable frame portion 2200 and can be rotated by receiving power from the driving source portion 2410. The guide portion 2430 is formed to extend along a longitudinal central axis and can rotate in a clockwise or counterclockwise direction with the longitudinal central axis as a rotation center axis.

[0202] According to one embodiment of the present invention, the longitudinal center axis of the guide portion 2430 can be formed identically to the central axis AX1 of movement of the movable frame portion 2200 relative to the fixed frame portion 2300. However, the present invention is not limited thereto and various modifications are possible. For example, the guide portion 2430 can be formed parallel to and aligned with the central axis AX1 of movement of the movable frame portion 2200 relative to the fixed frame portion 2300.

[0203] Reference Figure 4 and Figure 5 In one embodiment of the present invention, the guide portion 2430 has a thread 2431 formed along its outer circumferential surface, and the block portion 2450 described later opposite to the outer circumferential surface of the guide portion 2430 may have a thread groove formed along its inner circumferential surface.

[0204] Therefore, when the guiding portion 2430 receives power from the driving portion 2400 and rotates with the longitudinal center axis as the rotation center axis, the block portion 2450 prevents the rotation and is fixed to the fixed frame portion 2300, and since a thread groove portion is formed along the inner circumferential surface opposite to the guiding portion 2430, the guiding portion 2430 and the block portion 2450 can move relative to each other.

[0205] That is, the guide portion 2430 is connected through the block portion 2450, and is fixed in position as the guide portion 2430 formed with the thread 2431 rotates, and the guide portion 2430 can be formed in a preset direction (in Figure 8 The vertical direction is based on the reference.

[0206] Therefore, the guide portion 2430 and the movable frame portion 2200 coupled with the guide portion 2430 may move relative to the fixed frame portion 2300 .

[0207] Reference Figure 4 and Figure 8 According to an embodiment of the present invention, the block portion 2450 is coupled to the fixed frame portion 2300 and is movable on the guide portion 2430 .

[0208] That is, the block portion 2450 may be relatively movable with respect to the guide portion 2430. The block portion 2450 may be connected to the fixing frame portion 2300 to surround the guide portion 2430.

[0209] The block portion 2450 may have a thread groove formed on an inner circumferential surface thereof to correspond to the shape of the thread 2431 formed along the outer circumferential surface of the guide portion 2430. The guide portion 2430 may penetrate the block portion 2450 and be connected to the block portion 2450.

[0210] Reference Figure 4 and Figure 8 , the block portion 2450 can be fixed and connected to the fixed frame portion 2300. Therefore, the guide portion 2430 rotates clockwise or counterclockwise by receiving power from the driving source portion 2410. At this time, the block portion 2450 is in a state of being non-rotatably fixed to the fixed frame portion 2300, so the guide portion 2430 moves relative to the block portion 2450.

[0211] That is, when the guide portion 2430 and the block portion 2450 move relative to each other, the movable frame portion 2200 may move relative to the fixed frame portion 2300 along the movement center axis AX1.

[0212] According to one embodiment of the present invention, the driving portion 2400 receives power generated from the driving source portion 2410 and converts the rotational motion of the guiding portion 2430 into linear motion, but is not limited thereto. Various modifications may be made within the technical concept of relative movement of the movable frame portion 2200 coupled to the leg massage body 2100 relative to the fixed frame portion 2300, for example, power may be transmitted by means of a rack and pinion.

[0213] Reference Figures 4 to 8 According to an embodiment of the present invention, the length sensor portion 2500 is provided at the movable frame portion 2200 and the fixed frame portion 2300 , and when the movable frame portion 2200 and the fixed frame portion 2300 move relative to each other, the relative movement length can be measured.

[0214] In the present invention, "measuring the relative moving length" means that when the moving frame portion 2200 coupled to the leg massage body 2100 that accommodates the user's legs is fixed to one side (with a rotation center axis AX2) Figure 8 When the fixed frame portion 2300 (with the upper side as a reference) moves relatively, the change in the leg length is measured.

[0215] 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 accommodating the user's feet can be regarded as the leg length, and the leg length can change when the movable frame part 2200 and the fixed frame part 2300 coupled to the leg massage body 2100 move relative to each other.

[0216] The length sensor part 2500 according to an embodiment of the present invention can accurately recognize a change in the length of the leg by measuring a relative movement length when the moving frame part 2200 and the fixed frame part 2300 move relative to each other.

[0217] In addition, since the change in the leg length can be accurately recognized, there is an effect that the position of the user's foot accommodated in the leg massage body 2100 coupled to the moving frame part 2200 can also be accurately recognized.

[0218] Reference Figures 4 to 8 The length sensor portion 2500 according to an 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 disposed outside a sensor plate 2530 to be described later and can move on the sensor plate 2530.

[0220] Specifically, when the moving frame portion 2200 and the fixed frame portion 2300 move relative to each other, the sensor body 2510 fixed to the moving frame portion 2200 may move on the sensor plate 2530 fixed to the fixed frame portion 2300 .

[0221] The sensor body 2510 according to an embodiment of the present invention can be spaced apart from the sensor plate 2530 by a predetermined distance, thereby reducing friction between the sensor body 2510 and the sensor plate 2530 and preventing the sensor body 2510 and the sensor plate 2530 from being damaged by friction.

[0222] However, the present invention is not limited thereto, and various modifications may be made. For example, the sensor body 2510 and the sensor plate 2530 may be in surface contact and move relative to each other.

[0223] According to one embodiment of the present invention, the sensor body 2510 is arranged and fixed on the movable frame part 2200, and the sensor plate 2530 is arranged and fixed on the fixed frame part 2300, but is not limited to this.

The light emitting portion 2511 emits light, and the light receiving portion 2513 receives the light emitted from the light emitting portion 2511.

[0227] Reference Figure 6 According to an embodiment of the present invention, the light emitting portion 2511 and the light receiving portion 2513 may be arranged to face each other, and the sensor plate 2530 arranged on the inner side of the sensor body 2510 may be arranged between the light emitting portion 2511 and the light receiving portion 2513 .

[0228] Reference Figure 6 Compared with the light receiving portion 2513, the light emitting portion 2511 is arranged relatively close to the movable frame portion 2200, but is not limited thereto, and various deformation implementations can be performed. For example, compared with the light emitting portion 2511, the light receiving portion 2513 is arranged relatively close to the movable frame portion 2200.

[0229] According to an 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 to correspond to the plurality of light emitting units 2511 .

[0230] According to an embodiment of the present invention, three light emitting parts 2511 and three light receiving parts 2513 are respectively provided, but the present invention is not limited thereto and various modifications can be made. For example, more than four light receiving parts can be provided.

[0231] As an optional embodiment, only one light emitting portion 2511 and light receiving portion 2513 may be provided, and the moving length of the sensor plate 2530 may be measured by sensing that the light emitted from the light emitting portion 2511 is received by the light receiving portion 2513 .

[0232] According to an embodiment of the present invention, the light emitted from the light emitting portion 2511 may pass through a slit portion formed on a sensor plate 2530 to be described later and be transmitted to the light receiving portion 2513 .

[0233] It has the following effect: whether the light source emitted from the multiple light-emitting parts 2511 is transmitted to the multiple light-receiving parts 2513 can be changed according to the slit part formed on the sensor plate 2530. When the light-receiving part 2513 receives the light source, the relevant information is transmitted to the control part 1200, so that when the movable frame part 2200 moves relative to the fixed frame part 2300, the position of the movable frame part 2200 can be accurately identified.

[0234] In addition, accurately identifying the position of the moving frame part 2200 means that the position of the leg massage body 2100 coupled to the moving frame part 2200 can be identified, and the change in the length of the user's leg accommodated in the leg massage body 2100 can be accurately measured.

[0235] Reference Figures 4 to 8 The sensor plate 2530 according to an embodiment of the present invention is disposed on an irradiation path of a light source irradiated from the sensor body 2510 and may be formed with a slit portion so that the light source can pass therethrough.

[0236] The sensor board 2530 according to an embodiment of the present invention may be formed of a plastic material, specifically, acrylonitrile butadiene styrene (ABS) or polycarbonate (PC).

[0237] Reference Figure 5 and Figure 7 The sensor board 2530 according to an embodiment of the present invention may be coupled to the fixed frame portion 2300. Although not shown in the drawings, the sensor board 2530 may be fixed to the fixed frame portion 2300 by fastening members such as bolts.

[0238] Reference Figure 4 and Figure 5 The sensor plate 2530 according to an embodiment of the present invention may be connected to the side portion with the center portion of the fixing frame portion 2300 as a reference.

[0239] Therefore, when the driving portion 2400 located at the center of the fixed frame portion 2300 , specifically, the index portion 2430 and the block portion 2450 , relatively moves, interference with the sensor plate 2530 can be prevented.

[0240] Reference Figure 5 According to an embodiment of the present invention, the sensor plate 2530 is arranged along the length direction (in Figure 5 The structure is extended in the up and down directions based on the reference, and can be fixed to the fixed frame portion 2300.

[0241] Reference Figure 5 , the sensor plate 2530 can be coupled to the fixed frame portion 2300 at multiple points. Specifically, the two end portions (with Figure 5 The upper and lower ends (based on the upper and lower ends) can be combined with the fixing frame part 2300 along the length direction of the sensor plate 2530.

[0242] Reference Figure 5 , at both ends of the sensor plate 2530 (with Figure 5 The upper and lower ends (based on the reference) can protrude outward to form a contact portion 2535.

[0243] There are multiple contact parts 2535, and one contact part 2535a can be formed at the upper end of the sensor plate 2530 (with Figure 5 Another contact portion 2535b may be formed at the other end of the sensor plate 2530 (with Figure 5 as the lower end of the reference).

[0244] A fastening hole portion (not designated by a reference numeral) may be formed in the contact portion 2535 so that a fastening member (not shown) may pass through. The fastening member may pass through the fastening hole portion and be fastened to the fixing frame portion 2300 .

[0245] The following effects are achieved: due to the formation of the two ends of the sensor plate 2530 (with Figure 5 Multiple contact portions 2535a, 2535b (with the upper and lower ends as the reference) are fixed to the fixed frame portion 2300, so the position of the sensor plate 2530 formed with the slit portion does not change, and when the sensor plate 2530 and the sensor body 2510 move relative to each other, the relative movement length of the fixed frame portion 2300 and the movable frame portion 2200 can be accurately measured and identified.

[0246] Reference Figures 5 to 7 In one embodiment of the present invention, a slit portion may be formed in the sensor plate 2530 to allow light emitted from the sensor body 2510 to pass through. The sensor plate 2530 may pass through the sensor body 2510 and be disposed inside the sensor body 2510. Specifically, it may be disposed between the light emitting portion 2511 and the light receiving portion 2513 provided in the sensor body 2510.

[0247] Since the slit portion is formed in the sensor plate 2530 , the light emitted from the light emitting portion 2511 in the region where the slit portion is formed in the sensor plate 2530 can be transmitted to the light receiving portion 2513 through the slit portion.

[0248] When the light receiving portion 2513 receives the light source, the related information can be transmitted to the control portion 1200 , and the position of the sensor body 2510 on the sensor plate 2530 can be known based on the information.

[0249] From another perspective, the movable frame portion 2200 to which the sensor body 2510 is fixed moves relative to the fixed frame portion 2300 to which the sensor plate 2530 is fixed, and the position of the movable frame portion 2200 moving relative to the fixed frame portion 2300 can be recognized.

[0250] From another perspective, the leg massage body 2100 receiving the user's legs is coupled to the movable frame portion 2200 , and the position of the leg massage body 2100 coupled to the movable frame portion 2200 moving relative to the fixed frame portion 2300 can be recognized.

[0251] Therefore, there is an effect that a change in the leg length can be accurately recognized by measuring the relative movement length when the movable frame portion 2200 and the fixed frame portion 2300 move relative to each other.

[0252] In addition, since the change in the leg length can be accurately recognized, there is an effect that the position of the user's foot accommodated in the leg massage body 2100 coupled to the moving frame part 2200 can also be accurately recognized.

[0253] Reference Figure 7 According to an embodiment of the present invention, the slit portion formed on the sensor plate 2530 may include a plurality of slits 2532a, 2532b, and 2532c. The plurality of slits 2532a, 2532b, and 2532c may be spaced apart along the width direction of the sensor plate 2530.

[0254] Reference Figure 6 The plurality of slits 2532 may correspond to the plurality of light emitting portions 2511 and light receiving portions 2513 arranged along the width direction of the sensor body 2510 .

[0255] Therefore, when the light source is irradiated from any one of the plurality of light-emitting portions 2511 to the light-receiving portion 2513 opposite to the light-emitting portion 2511 , the light source can be transmitted to the light-receiving portion 2513 through the slit 2532 located between the light-emitting portion 2511 and the light-receiving portion 2513 .

[0256] Reference Figure 7 , a plurality of slits 2532 may be provided along a width direction of the sensor plate 2530 .

[0257] Specifically, the plurality of slits 2532 formed on the sensor plate 2530 may be formed along virtual axes VL1, VL2, and VL3, which are formed parallel to the length direction of the sensor plate 2530 (in units of degrees). Figure 7 The vertical direction is the center axis of the reference.

[0258] A plurality of virtual axes VL1 , VL2 , and VL3 may be disposed parallel to each other and spaced apart in a width direction of the sensor plate 2530 .

[0259] The slit 2532 formed in the sensor plate 2530 may be formed along any one of the virtual axes VL1 , VL2 , and VL3 .

[0260] Reference Figure 7 According to an embodiment of the present invention, the slits 2532 provided in the slit portion may alternately form open sections OS and closed sections CS along the virtual axis.

[0261] Reference Figure 7 The slit 2532 is provided in plurality and may include a first slit 2532a, a second slit 2532b and a third slit 2532c.

[0262] The first slit 2532a of the plurality of slits 2532a, 2532b, 2532c 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.

[0263] The open section OS and the closed section CS respectively formed in the first slit 2532 a , the second slit 2532 b , and the third slit 2532 c may be formed at different sections along the longitudinal center axis of the sensor plate 2530 .

[0264] Reference Figure 7 The open interval OS formed in the plurality of slits 2532a, 2532b, and 2532c can be formed in the length direction of the sensor plate 2530 (in Figure 7 At least one is formed along the width direction of the sensor plate 2530 at a predetermined point (with the up and down directions as a reference).

[0265] Reference Figure 7 At the first point P1 , a plurality of, specifically three, open sections OS of the slits 2532 a , 2532 b , and 2532 c may be formed along the width direction of the sensor plate 2530 .

[0266] At the second point P2, the open section OS may be formed only at the first slit 2532a, and at the third point P3, the open section OS may be formed at the first slit 2532a and the second slit 2532b.

[0267] At the fourth point P4, the open section OS may be formed only at the second slit 2532b, and at the fifth point P5, the open section OS may be formed at the second slit 2532b and the third slit 2532c.

[0268] At the sixth point P6, the open section OS may be formed only at the third slit 2532c, and at the seventh point P7, the open section OS may be formed at the first slit 2532a and the third slit 2532c.

[0269] The first point P1 to the seventh point P7 refer to positions of the sensor body 2510 that moves on the sensor plate 2530 fixed to the fixed frame portion 2300 when the fixed frame portion 2300 and the movable frame portion 2200 move relative to each other.

[0270] That is, the light-emitting portion 2511 and the light-receiving portion 2513 are arranged opposite to each slit 2532, and in the open interval OS of the slit 2532, the light source irradiated from the light-emitting portion 2511 can be transmitted to the light-receiving portion 2513, and in the closed interval CS of the slit 2532, the light source irradiated from the light-emitting portion 2511 is blocked by the sensor plate 2530 forming the closed interval CS, and therefore cannot be transmitted to the light-receiving portion 2513.

[0271] Reference Figure 8 , which has the following effect: when the movable frame portion 2200 moves relative to the fixed frame portion 2300, the sensor body 2510 moves on the sensor plate 2530, detecting the open interval OS and the closed interval CS formed in the multiple slits 2532a, 2532b, and 2532c, respectively, so that the relative movement length of the movable frame portion 2200 and the fixed frame portion 2300 when they move relative to each other can be measured.

[0272] In addition, there is an effect that a change in the leg length can be accurately recognized by measuring the relative movement length when the movable frame portion 2200 and the fixed frame portion 2300 move relative to each other.

[0273] In addition, since the change in the leg length can be accurately recognized, there is an effect that the position of the user's foot accommodated in the leg massage body 2100 coupled to the moving frame part 2200 can also be accurately recognized.

[0274] Reference Figure 5 and Figure 7 In the sensor plate 2530 according to an embodiment of the present invention, the support groove portion 2533 may be formed in a groove shape so that the support portion 2350 connecting both sides of the fixing frame portion 2300 may be disposed inside.

[0275] Therefore, when the sensor board 2530 and the fixing frame part 2300 are combined, the support part 2350 and the sensor board 2530 may be prevented from interfering.

[0276] Reference Figure 7 The support groove portion 2533 may protrude toward the side of the support portion 2350 to form a support connection portion 2534, and the support connection portion 2534 may be inserted into and fastened to the support portion 2350. Therefore, the sensor board 2530 may be stably fixed to the fixing frame portion 2300.

[0277] According to an embodiment of the present invention, the sensor plate 2530 and the support portion 2350 are in contact via the support connection portion 2534 , but the present invention is not limited thereto and various modifications may be made. For example, the support groove 2533 formed in the sensor plate 2530 may be separated from the support portion 2350 .

[0278] Reference Figure 4 、 Figure 5 and Figure 8 According to an embodiment of the present invention, the sensor cover 2550 covers the sensor body 2510 and can form a storage space therein for accommodating the sensor body 2510. The sensor cover 2550 is coupled to the fixing frame portion 2300 and can prevent the sensor body 2510 from being damaged by external foreign matter.

[0279] A through hole portion (not designated by a reference numeral) may be formed in the sensor cover 2550 so that the sensor plate 2530 can pass therethrough.

[0280] Therefore, the sensor cover 2550 that accommodates the sensor body 2510 is disposed on the outside of the sensor plate 2530. When the movable frame portion 2200 moves relative to the fixed frame portion 2300, the sensor body 2510 and the sensor cover 2550 that covers the sensor body 2510 can move along a predetermined direction (in degrees) on the sensor plate 2530. Figure 8 Move in the up and down direction based on the reference.

[0281] The working principle and effect of the massage device according to one embodiment of the present invention are described below.

[0282] Reference Figures 1 to 8 The massage device according to one embodiment of the present invention may include a body massage part 1000, a leg massage part 2000, and an arm massage part 3000. A plurality of leg massage parts 2000 may be provided, and the user's left and right feet may be accommodated in the plurality of leg massage parts 2000A and 2000B, respectively.

[0283] Specifically, the plurality of leg massage parts 2000A and 2000B may include a leg massage body 2100 , respectively, and the left and right feet of the user 10 may be inserted into, seated in, and accommodated in the plurality of leg massage bodies 2100 , respectively.

[0284] The plurality of leg massage parts 2000A and 2000B can receive an electric signal from the control part 1200 and be driven independently.

[0285] The leg massage part 2000 according to an embodiment of the present invention may include a leg massage body 2100, a movable frame part 2200, a fixed frame part 2300, a driving part 2400, and a length sensor part 2500. The fixed frame part 2300 is provided with a hinge shaft 2310 and can be hinged to the body massage part 1000, specifically, the frame part 1100, along a rotation center axis AX2.

[0286] Since the rotation center axis AX2 is fixed, the fixed frame portion 2300 can rotate clockwise or counterclockwise with respect to the rotation center axis AX2 , but the linear movement of the fixed frame portion 2300 along the movement center axis AX1 can be restricted.

[0287] The moving frame portion 2200 is combined with the leg massaging body 2100 and is relatively movable with respect to the fixed frame portion 2300. The moving frame portion 2200 may include a moving frame body 2210 and a guide portion 2230.

[0288] The movable frame body 2210 according to an embodiment of the present invention is connected to the leg massage body 2100, and the guide portion 2230 can be combined with the movable frame body 2210. The guide portion 2230 can be inserted into the guide insertion portion 2330 formed in the fixed frame portion 2300 and can move along the guide insertion portion 2330.

[0289] When the guide portion 2230 provided on the moving frame portion 2200 is inserted into the guide insertion portion 2330 formed on the fixed frame portion 2300 , the moving frame portion 2200 can move relative to the fixed frame portion 2300 along the movement center axis AX1 .

[0290] When the moving frame part 2200 moves relative to the fixed frame part 2300 , the leg massage body 2100 connected to the moving frame part 2200 may move relatively together relative to the fixed frame part 2300 , and the leg length of the user 10 may be adjusted.

[0291] That is, when the moving frame part 2200 and the fixed frame part 2300 relatively move, the length from the hinge shaft 2310 formed at the fixed frame part 2300 to the bottom of the leg massage body 2100 connected to the moving frame part 2200 may be adjusted.

[0292] Reference Figure 4 and Figure 8 The driving portion 2400 according to an embodiment of the present invention may include a driving source portion 2410 , a guiding portion 2430 , and a block portion 2450 . The guiding portion 2430 is rotated by power generated by the driving source portion 2410 .

[0293] Reference Figure 8 , the guide portion 2430 is coupled to the moving frame portion 2200 and rotated by receiving power from the driving source portion 2410 , and the block portion 2450 may be fixed to the fixed frame portion 2300 .

[0294] The guide portion 2430 and the block portion 2450 are connected by a threaded manner. A thread groove portion may be formed along the inner circumferential surface of the block portion 2450 to correspond to the thread 2431 formed along the outer circumferential surface of the guide portion 2430 .

[0295] Since the block portion 2450 is fixed to the fixed frame portion 2300 , when the guide portion 2430 receives power from the driving source portion 2410 and rotates, the guide portion 2430 can move along the movement center axis AX1 on the block portion 2450 .

[0296] Therefore, the movable frame portion 2200 can move relative to the fixed frame portion 2300 , and the leg massage body 2100 coupled to the movable frame portion 2200 can move relative to the fixed frame portion 2300 , thereby adjusting the leg length.

[0297] Reference Figures 4 to 8 The length sensor part 2500 is set in the movable frame part 2200 and the fixed frame part 2300, and when the movable frame part 2200 and the fixed frame part 2300 move relative to each other, the length sensor part 2500 measures the relative movement length. The length sensor part 2500 may include a sensor body 2510, a sensor plate 2530 and a sensor cover 2550.

[0298] Reference Figure 7 A slit portion is formed on the sensor plate 2530 , and the slit portion may include a plurality of slits 2532 .

[0299] The plurality of slits 2532 may be spaced apart along the width direction of the sensor plate 2530, and an open section OS and a closed section CS may be alternately formed in each slit 2532 along virtual axes VL1, VL2, and VL3 along the length direction of the sensor plate 2530 (in units of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44 Figure 7 As a reference up and down direction) is formed.

[0300] The light source irradiated from the sensor body 2510, specifically the light emitting portion 2511, can be transmitted to the light receiving portion 2513 arranged opposite to the light emitting portion 2511 through the open interval OS set in the slit 2532. When the movable frame portion 2200 moves relative to the fixed frame portion 2300, the position of the movable frame portion 2200 can be identified.

[0301] Reference Figure 7 , along the length direction of the sensor plate 2530 (in Figure 7 At a plurality of points P1 to P7 formed in the up-down direction (with φ as a reference), the open sections OS and the closed sections CS of the plurality of slits 2532a, 2532b, and 2532c may be formed differently.

[0302] Specifically, according to the width direction (in Figure 7 The position of the sensor body 2510 moving on the sensor plate 2530 is recognized by determining whether the open sections OS formed on the plurality of slits 2532a, 2532b, and 2532c provided in the left-right direction (with φ being a reference) overlap.

[0303] From another perspective, since the sensor body 2510 is fixed to the moving frame portion 2200 , it is possible to recognize the position of the moving frame portion 2200 that moves relative to the fixed frame portion 2300 to which the sensor plate 2530 is fixed.

[0304] Identifying the position of the movable frame portion 2200 relative to the fixed frame portion 2300 means that the position of the leg massage body 2100 coupled to the movable frame portion 2200 can be identified, and when the movable frame portion 2200 moves relative to the fixed frame portion 2300, the position change of the leg massage body 2100 can be identified.

[0305] In addition, changes in the length of the legs of the user accommodated in the leg massage body 2100 can be accurately recognized.

[0306] In addition, since the change in the leg length can be accurately recognized, there is an effect that the position of the user's foot accommodated in the leg massage body 2100 coupled to the moving frame part 2200 can also be accurately recognized.

[0307] Reference Figure 7 and Figure 8 A plurality of contact portions 2535 may be formed protruding from one side of the sensor plate 2530. Figure 7 The two ends of the vertical direction (based on Figure 7 A contact portion 2535 is protruded and formed on the upper and lower ends of the base, and can be connected to the fixed frame portion 2300.

[0308] Therefore, there is an effect that the sensor board 2530 can be firmly fixed and coupled to the fixing frame part 2300 .

[0309] In the massage device according to one embodiment of the present invention, when the leg massage part 2000 is driven, the length sensor part 2500 accurately measures the relative movement length of the fixed frame part 2300 and the movable frame part 2200, thereby having the effect of accurately identifying the position of the leg massage body 2100 based on the relative movement length.

[0310] That is, it has the following effect: the sensor body 2510 senses the light source through the multiple slits 2532 formed in the sensor plate 2530, so that the position of the movable frame part 2200 and the leg massage body 2100 combined with the movable frame part 2200 relative to the fixed frame part 2300 along the moving center axis AX1 can be accurately identified, and the leg length can be accurately adjusted based on the position information.

[0313] Reference Figures 1 to 3 、 Figure 9 and Figure 10 According to another embodiment of the present invention, a massage device may include a body massage part 1000 , a leg massage part 2000 , and an arm massage part 3000 .

[0314] Reference Figure 9 and Figure 10 Compared with the massage device 100 according to one embodiment of the present invention, the leg massage part 2000' of the massage device according to another embodiment of the present invention, specifically the structure of the length sensor part 2500' is different. Therefore, the following description will focus on the length sensor part 2500'.

[0315] Reference Figure 9 and Figure 10 According to another embodiment of the present invention, the length sensor portion 2500' is provided at the movable frame portion 2200 and the fixed frame portion 2300, and when the movable frame portion 2200 and the fixed frame portion 2300 move relative to each other, the relative movement length can be measured.

[0316] The length sensor portion 2500 ′ can accurately recognize a change in the leg length by measuring a relative movement length when the moving frame portion 2200 and the fixed frame portion 2300 move relative to each other.

[0317] In addition, since the change in the leg length can be accurately recognized, there is an effect that the position of the user's foot accommodated in the leg massage body 2100 coupled to the moving frame part 2200 can also be accurately recognized.

[0318] Reference Figure 9 and Figure 10 , the length sensor portion 2500 ′ may include a sensor body, a sensor plate 2530 ′ and a sensor cover 2550 ′.

[0319] Compared with the length sensor unit 2500 according to one embodiment of the present invention, the length sensor unit 2500 ′ according to another embodiment of the present invention has a difference in the structure of the sensor plate 2530 ′. Therefore, the following description focuses on the sensor plate 2530 ′.

[0320] Reference Figure 9 and Figure 10 According to another embodiment of the present invention, a sensor plate 2530' is disposed on an irradiation path of a light source irradiated from a sensor body, and may be formed with a slit portion 2532' to allow the light source to pass therethrough.

[0321] The sensor plate 2530 ′ according to another embodiment of the present invention may be formed of a metal material.

[0322] Since the sensor plate 2530 ′ is formed of a metal material, the thickness can be relatively thin compared to when it is formed of a plastic material, and friction generated by contact with the sensor body can be reduced.

[0323] In addition, it has the effect of preventing the sensor plate 2530' from being damaged due to friction with the sensor body.

[0324] Reference Figure 9 , the sensor board 2530' may be coupled to the fixed frame portion 2300. Although not shown in the drawings, the sensor board 2530' may be fixed to the fixed frame portion 2300 by a fastening member such as a bolt.

[0325] Reference Figure 9 The sensor plate 2530′ can be connected to the side portion with the center portion of the fixed frame portion 2300 as a reference. Therefore, when the driving portion 2400 located in the center portion of the fixed frame portion 2300, specifically, the guide portion 2430 and the block portion 2450, move relatively, interference with the sensor plate 2530′ can be prevented.

[0326] Reference Figure 9 According to another embodiment of the present invention, the sensor plate 2530' is arranged along the length direction (in Figure 9 The structure is extended in the up and down directions based on the reference, and can be fixed to the fixed frame portion 2300.

Specifically, the two ends of the sensor plate 2530' in the longitudinal direction (with Figure 9 The upper and lower ends of the frame portion 2300 can be combined with the fixed frame portion 2300.

[0328] Reference Figure 9 , at both ends of the sensor plate 2530' (with Figure 9 The upper and lower ends (based on the reference) can protrude outward to form a contact portion 2535'.

[0329] There are multiple contact parts 2535', and one contact part 2535'a can be formed at the upper end of the sensor plate 2530' (with Figure 9 Another contact portion 2535'b may be formed at the other end of the sensor plate 2530' (with Figure 9 as the lower end of the reference).

[0330] A fastening hole portion (not designated by a reference numeral) may be formed in the contact portion 2535 ′ so that a fastening member (not shown) may pass through. The fastening member may pass through the fastening hole portion and be fastened to the fixing frame portion 2300 .

[0331] The following effects are achieved: due to the formation of the two ends of the sensor plate 2530' (with Figure 9 Multiple contact portions 2535`a, 2535`b (with the upper and lower ends as the reference) are fixed to the fixed frame portion 2300, so that the position of the sensor plate 2530` formed with the slit portion 2532` does not change, and when the sensor plate 2530` and the sensor body move relative to each other, the relative movement length of the fixed frame portion 2300 and the movable frame portion 2200 can be accurately measured and identified.

[0332] Reference Figure 9 and Figure 10 A slit 2532' may be formed in the sensor plate 2530' to allow light emitted from the sensor body to pass through. The sensor plate 2530' may be disposed inside the sensor body, specifically between the light emitting portion and the light receiving portion of the sensor body.

[0333] Since the slit portion 2532 ′ is formed in the sensor plate 2530 ′, the light emitted from the light emitting portion in the region where the slit portion 2532 ′ is formed in the sensor plate 2530 ′ can be transmitted to the light receiving portion through the slit portion 2532 ′.

[0334] When the light receiving portion receives the light source, the related information can be transmitted to the control portion 1200 , and the position of the sensor body on the sensor plate 2530 ′ can be known based on the information.

[0335] From another perspective, the movable frame portion 2200 to which the sensor body is fixed moves relative to the fixed frame portion 2300 to which the sensor plate 2530 ′ is fixed, and the position of the movable frame portion 2200 moving relative to the fixed frame portion 2300 can be identified.

[0336] From another perspective, the leg massage body 2100 receiving the user's legs is coupled to the movable frame portion 2200 , and the position of the leg massage body 2100 coupled to the movable frame portion 2200 moving relative to the fixed frame portion 2300 can be recognized.

[0337] Therefore, there is an effect that a change in the leg length can be accurately recognized by measuring the relative movement length when the movable frame portion 2200 and the fixed frame portion 2300 move relative to each other.

[0338] In addition, since the change in the leg length can be accurately recognized, there is an effect that the position of the user's foot accommodated in the leg massage body 2100 coupled to the moving frame part 2200 can also be accurately recognized.

[0339] Reference Figure 9 and Figure 10 , the width of the slit portion 2532 ′ formed in the sensor plate 2530 ′ according to another embodiment of the present invention may be different along the length direction of the sensor plate 2530 ′.

[0340] Similar to the sensor body 2510 according to one embodiment of the present invention, the sensor body according to another embodiment of the present invention may include a plurality of light emitting parts and light receiving parts, and the plurality of light emitting parts and light receiving parts may be arranged along the width direction of the sensor body (in the form of Figure 10 left and right directions as a reference).

[0341] Reference Figure 10 The width of the slit portion 2532' formed in the sensor plate 2530' is equal to the width of the slit portion 2532' along the length direction of the sensor plate 2530' (in terms of Figure 10 The vertical direction (based on the vertical direction) is different, and in the first section 2532'a, the slit portion 2532' can be formed with a relatively wide first width D1.

[0342] In the second section 2532`b connected to the first section 2532`a, the slit portion 2532` according to another embodiment of the present invention can have a second width D2 that is relatively narrower than the first width D1. In the third section connected to the second section 2532`b, a closed section can be formed along the width direction of the sensor plate 2530` to block the passage of light.

[0343] That is, in the first interval 2532`a, the light source irradiated from the multiple light-emitting parts can pass through the slit portion 2532` and be transmitted to the multiple light-receiving parts, and in the second interval 2532`b, the light source irradiated from a part of the multiple light-emitting parts can be transmitted to the light-receiving part arranged opposite thereto.

[0344] In addition, in the third section, since the light emitted from the plurality of light emitting portions cannot pass through the sensor plate 2530' due to the closed section, the light may not be transmitted to any of the plurality of light receiving portions.

[0345] In the sensor plate 2530' according to another embodiment of the present invention, since the width of the slit portion 2532' through which the light source can pass in the interval formed along the moving center axis AX1 of the movable frame portion 2200 relative to the fixed frame portion 2300 is different, the relative movement length of the movable frame portion 2200 and the fixed frame portion 2300 when they move relative to each other is measured according to whether the light source is received in each interval, so that the change in the leg length can be accurately identified.

[0346] In addition, since the change in the leg length can be accurately recognized, there is an effect that the position of the user's foot accommodated in the leg massage body 2100 coupled to the moving frame part 2200 can also be accurately recognized.

[0347] Reference Figure 10 , a support groove portion 2533 ′ may be formed in a groove shape in the sensor plate 2530 ′ so that the support portion 2350 connecting both sides of the fixing frame portion 2300 may be disposed inside.

[0348] Therefore, when the sensor board 2530 ′ and the fixing frame part 2300 are combined, the support part and the sensor board 2530 ′ may be prevented from interfering with each other.

[0349] In the length sensor portion 2500' according to another embodiment of the present invention, in addition to forming a single slit portion 2532' and extending along the length direction (in the order of Figure 10 Except for the different widths in the up and down directions (based on the vertical direction), the sensor body 2510 and the sensor cover 2550 of the length sensor part 2500 according to an embodiment of the present invention have the same structure, working principle and effect, so detailed description is omitted within the scope of repetition.

[0350] According to another embodiment of the massage device of the present invention, regarding the structure of the leg massage part 2000', except for the difference in the length sensor part 2500', the structure, working principle and effect of the movable frame part 2200, the fixed frame part 2300 and the driving part 2400 are the same, so detailed description is omitted within the scope of repetition.
