[0219] It has the following effects: whether the light sources irradiated from the multiple light-emitting parts 2511 are transmitted to the multiple light-receiving parts 2513 can be changed according to the slit parts formed on the sensor plate 2530, and when the light-receiving parts 2513 receive the light sources, the information related thereto 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.

[0220] In addition, accurately recognizing 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 recognized, and the change in the leg length of the user accommodated in the leg massage body 2100 can be accurately measured.

[0221] 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 through.

[0222] The sensor board 2530 according to an embodiment of the present invention may be formed of a plastic material, specifically, may be formed of acrylonitrile butadiene styrene (ABS) or polycarbonate (PC).

[0223] Reference Figure 5 and Figure 7 According to an embodiment of the present invention, the sensor board 2530 may be combined with the fixed frame part 2300. Although not shown in the drawings, the sensor board 2530 may be fixed to the fixed frame part 2300 by a fastening member such as a bolt.

[0224] 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 central portion of the fixing frame portion 2300 as a reference.

[0225] Therefore, there is an effect that when the driving part 2400 located at the central part of the fixed frame part 2300, specifically, the index part 2430 and the block part 2450 move relatively, interference with the sensor plate 2530 can be prevented.

[0226] Reference Figure 5 According to an embodiment of the present invention, the sensor plate 2530 is arranged along the length direction (in Figure 5The structure is formed to extend in the up and down directions based on the reference, and can be fixed to the fixed frame part 2300.

[0227] Reference Figure 5 The sensor plate 2530 may be coupled to the fixed frame portion 2300 at multiple points. Figure 5 The upper and lower ends (based on the upper and lower ends) can be combined with the fixed frame part 2300 along the length direction of the sensor plate 2530.

[0228] 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.

[0229] A plurality of contact portions 2535 are provided, and one contact portion 2535a may be formed at an upper end portion (with a 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).

[0230] 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 in the drawing) may pass through, and the fastening member may pass through the fastening hole portion and be fastened to the fixing frame portion 2300 .

[0231] The following effects are achieved: due to the formation of the two ends of the sensor plate 2530 (with Figure 5 A plurality of contact portions 2535a, 2535b (with the upper and lower ends as a reference) are fixed to the fixed frame portion 2300, so that 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.

[0232] Reference Figures 5 to 7 In the sensor plate 2530 according to an embodiment of the present invention, a slit portion may be formed so that the light source irradiated from the sensor body 2510 can pass through. The sensor plate 2530 may pass through the sensor body 2510 and be disposed inside the sensor body 2510, specifically, may be disposed between the light emitting portion 2511 and the light receiving portion 2513 disposed in the sensor body 2510.

[0233] 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.

[0234] 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.

[0235] From another perspective, the movable frame part 2200 to which the sensor body 2510 is fixed moves relative to the fixed frame part 2300 to which the sensor plate 2530 is fixed, and the position of the movable frame part 2200 moving relative to the fixed frame part 2300 can be identified.

[0237] Therefore, there is an effect that a change in the leg length can be accurately recognized by measuring the relative movement length when the moving frame part 2200 and the fixed frame part 2300 move relative to each other.

[0238] 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.

The plurality of slits 2532a, 2532b, and 2532c may be spaced apart in the width direction of the sensor plate 2530.

[0240] 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 .

[0241] 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 .

[0242] Reference Figure 7 , multiple slits 2532 can be arranged along the width direction of the sensor plate 2530.

[0243] Specifically, the plurality of slits 2532 formed on the sensor plate 2530 may be formed along virtual axes VL1, VL2, and VL3, and the virtual axes VL1, VL2, and VL3 are formed to be parallel to the length direction of the sensor plate 2530 (in Figure 7 The vertical direction is the center axis of the reference.

[0244] A plurality of virtual axes VL1 , VL2 , and VL3 may be disposed in parallel with each other and spaced apart in a width direction of the sensor plate 2530 .

[0245] The slit 2532 formed in the sensor plate 2530 may be formed along any one of the virtual axes VL1 , VL2 , and VL3 .

[0249] 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 central axis in the longitudinal direction of the sensor plate 2530 .

[0250] Reference Figure 7 The open interval OS formed in the plurality of slits 2532a, 2532b, and 2532c may be formed along 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).

[0251] 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 .

[0252] 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.

[0253] At the fourth point P4, the open section OS may be formed only at the second slit 2532 b, and at the fifth point P5, the open section OS may be formed at the second slit 2532 b and the third slit 2532 c.

[0254] At the sixth point P6, an open section OS may be formed only at the third slit 2532c, and at the seventh point P7, an open section OS may be formed at the first slit 2532a and the third slit 2532c.

[0255] 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 relatively.

[0256] 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.

[0257] 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, and detects the open interval OS and the closed interval CS respectively formed in the plurality of slits 2532a, 2532b, and 2532c, thereby measuring the relative movement length of the movable frame portion 2200 and the fixed frame portion 2300 when they move relative to each other.

[0258] 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 moving frame part 2200 and the fixed frame part 2300 move relative to each other.

[0259] 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.

[0260] Reference Figure 5 and Figure 7 , the sensor plate 2530 according to an embodiment of the present invention may form a support groove portion 2533 in a groove shape so that the support portion 2350 connecting both sides of the fixing frame portion 2300 may be disposed inside.

[0261] 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.

[0262] Reference Figure 7 The support groove portion 2533 may protrude toward the side direction of the support portion 2350 to form a support connection portion 2534, and the support connection portion 2534 may be inserted and fastened to the support portion 2350. Therefore, there is an effect that the sensor board 2530 can be stably fixed to the fixing frame portion 2300.

[0263] According to an embodiment of the present invention, the sensor plate 2530 and the support portion 2350 are in contact through the support connection portion 2534, but the present invention is not limited thereto and various modifications may be made. For example, the support groove portion 2533 formed in the sensor plate 2530 and the support portion 2350 may be separated.

[0264] 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 receiving space inside to receive the sensor body 2510. The sensor cover 2550 is combined with the fixing frame part 2300 and has the effect of preventing the sensor body 2510 from being damaged by external foreign matter.

[0265] The sensor cover 2550 may be formed with a through hole portion (not shown) so that the sensor plate 2530 can pass therethrough.

[0266] Therefore, the sensor cover 2550 accommodating the sensor body 2510 is disposed on the outer side 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 covering 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.

[0267] The working principle and effect of the massage device according to one embodiment of the present invention are described as follows.

[0268] Reference Figures 1 to 8 According to an embodiment of the present invention, the massage device 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 foot and right foot may be accommodated in the plurality of leg massage parts 2000A and 2000B, respectively.

[0269] Specifically, the plurality of leg massage parts 2000A and 2000B may include leg massage bodies 2100 , respectively, and the left and right feet of the user 10 may be inserted into, placed in, and accommodated in the plurality of leg massage bodies 2100 , respectively.

[0270] The plurality of leg massage parts 2000A and 2000B may receive an electrical signal from the control part 1200 and be driven independently.

[0271] The leg massage part 2000 according to an embodiment of the present invention may include a leg massage body 2100, a moving 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 the rotation center axis AX2.

[0272] Since the rotation center axis AX2 is fixed, the fixed frame part 2300 can rotate in a clockwise direction or a counterclockwise direction with respect to the rotation center axis AX2, but the linear movement of the fixed frame part 2300 along the movement center axis AX1 can be restricted.

[0273] The moving frame part 2200 is combined with the leg massaging body 2100 and can be relatively moved with respect to the fixed frame part 2300. The moving frame part 2200 may include a moving frame body 2210 and a guide part 2230.

[0274] The moving frame body 2210 according to an embodiment of the present invention is connected to the leg massage body 2100, and the guide part 2230 may be combined with the moving frame body 2210. The guide part 2230 may be inserted into the guide insertion part 2330 formed in the fixed frame part 2300 and may move along the guide insertion part 2330.

[0275] When the guide portion 2230 provided in the moving frame portion 2200 is inserted into the guide insertion portion 2330 formed in the fixed frame portion 2300 , the moving frame portion 2200 can move relative to the fixed frame portion 2300 along the moving center axis AX1 .

[0276] When the moving frame part 2200 moves relative to the fixed frame part 2300 , the leg massaging bodies 2100 connected to the moving frame part 2200 may relatively move together relative to the fixed frame part 2300 , and the leg length of the user 10 may be adjusted.

[0277] That is, when the moving frame part 2200 and the fixed frame part 2300 are relatively moved, 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.

[0278] Reference Figure 4 and Figure 8 The driving part 2400 according to an embodiment of the present invention may include a driving source part 2410 , a guiding part 2430 , and a block part 2450 , and the guiding part 2430 is rotated by the power generated by the driving source part 2410 .

[0279] Reference Figure 8 , the guide part 2430 is coupled to the moving frame part 2200 and rotated by receiving power from the driving source part 2410 , and the block part 2450 may be fixed to the fixed frame part 2300 .

[0280] The indexing portion 2430 and the block portion 2450 are connected by threads, and 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 indexing portion 2430 .

[0281] 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 may move on the block portion 2450 along the movement center axis AX1 .

[0282] Therefore, the movable frame part 2200 can move relative to the fixed frame part 2300, and the leg massage body 2100 combined with the movable frame part 2200 can move relative to the fixed frame part 2300, so that the leg length can be adjusted.

[0283] Reference Figures 4 to 8 The length sensor part 2500 is set at the moving frame part 2200 and the fixed frame part 2300, and when the moving frame part 2200 and the fixed frame part 2300 move relatively, 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.

[0284] Reference Figure 7 A slit portion is formed on the sensor plate 2530 , and the slit portion may include a plurality of slits 2532 .

[0285] The plurality of slits 2532 may be spaced apart in 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 Figure 7 The vertical direction is based on the reference).

[0286] The light source irradiated from the sensor body 2510, specifically the light emitting part 2511, can be transmitted to the light receiving part 2513 arranged opposite to the light emitting part 2511 through the open interval OS arranged in the slit 2532. When the movable frame part 2200 moves relative to the fixed frame part 2300, the position of the movable frame part 2200 can be identified.

[0287] Reference Figure 7 , along the length direction of the sensor plate 2530 (in Figure 7 At multiple 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 multiple slits 2532a, 2532b, and 2532c may be formed differently.

[0288] 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 the left direction as a reference) overlap.

[0289] 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 is moving relative to the fixed frame portion 2300 to which the sensor plate 2530 is fixed.

[0290] 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.

[0291] In addition, changes in the leg length of the user accommodated in the leg massaging body 2100 can be accurately recognized.

[0292] 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.

[0293] Reference Figure 7 and Figure 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 on 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 protrudedly formed on the upper and lower ends of the base and can be connected to the fixed frame portion 2300.

[0294] Therefore, there is an effect that the sensor board 2530 can be firmly fixed and combined to the fixing frame part 2300 .

[0295] In a massage device according to an 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.

[0296] 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 movable center axis AX1 can be accurately identified, and the leg length can be accurately adjusted based on the position information.

The fastening member may pass through the fastening hole portion and be fastened to the fixing frame portion 2300 .

[0317] The following effects are achieved: due to the formation of the two ends of the sensor plate 2530' (with Fig. 9 A plurality of 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.

[0318] Reference Fig. 9 and Fig.10 A slit portion 2532' may be formed in the sensor plate 2530' so that the light source irradiated from the sensor body can pass through. The sensor plate 2530' may be disposed inside the sensor body through the sensor body, specifically, between the light emitting portion and the light receiving portion disposed in the sensor body.

[0319] 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 ′.

[0320] When the light receiving unit receives the light source, the information related thereto can be transmitted to the control unit 1200 , and the position of the sensor body on the sensor board 2530 ′ can be known based on the information.

[0321] From another perspective, the movable frame part 2200 to which the sensor body is fixed moves relative to the fixed frame part 2300 to which the sensor plate 2530 ′ is fixed, and the position of the movable frame part 2200 that moves relative to the fixed frame part 2300 can be identified.

[0322] From another perspective, the leg massage body 2100 accommodating the user's legs is coupled to the moving frame part 2200 , and the position of the leg massage body 2100 coupled to the moving frame part 2200 that moves relatively with respect to the fixed frame part 2300 can be recognized.

[0323] Therefore, there is an effect that a change in the leg length can be accurately recognized by measuring the relative movement length when the moving frame part 2200 and the fixed frame part 2300 move relative to each other.

[0324] 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.

[0325] Reference Fig. 9 and Fig.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 ′.

[0326] 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 Fig.10 left and right directions as the reference).

[0327] Reference Fig.10 The width of the slit portion 2532' formed in the sensor plate 2530' is along the length direction of the sensor plate 2530' (in Fig.10 The slit portion 2532' may be formed with a relatively wide first width D1 in the first section 2532'a.

[0328] 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 may 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 that blocks the passage of the light source may be formed along the width direction of the sensor plate 2530'.

[0329] 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.

[0330] 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.

[0331] 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, thereby accurately identifying the change in the leg length.

[0332] 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.

[0333] Reference Fig.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 at the inner side.

[0334] 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.

[0335] In the length sensor portion 2500' according to another embodiment of the present invention, in addition to the single slit portion 2532' formed and extending along the length direction (in Fig.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 one embodiment of the present invention have the same structure, working principle and effect, so detailed descriptions are omitted within the scope of repetition.

[0336] 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 structures, working principles and effects of the movable frame part 2200, the fixed frame part 2300 and the driving part 2400 are the same, so the detailed description is omitted within the scope of repetition.

[0337] Although the embodiments of the present invention have been described in more detail above with reference to the accompanying drawings, the present invention is not limited to these embodiments and can be implemented in various modifications without departing from the technical concept of the present invention.

[0338] Therefore, the embodiments disclosed in the present invention are not intended to limit the technical idea of ​​the present invention but are for explanation, and the scope of the technical idea of ​​the present invention is not limited by these embodiments.
