Description

massage device

[0001] The present invention relates to a massage device, and more particularly, to a massage device capable of improving the hip joint and leg stretching effect by separately driving a foot massage part and a calf massage part.

[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, the massage device provides a massage function to the user's legs, but there was a problem in that the massage effect was reduced as the leg stretching range was limited depending on the length of the user's legs.

[0006] Additionally, even though the length of the massage device is adjusted according to the length of the user's legs, there was a problem in that it did not reach the user's ankles and thus did not provide an ankle stretching function.

[0007] The problem to be solved by the present invention is to provide a massage device in which a foot massage part and a calf massage part can move relative to each other in a direction approaching each other, a direction away from each other, and / or in the same direction on a connecting frame part, and can improve the hip joint and leg stretching effect by being driven separately.

[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 part into which a user's leg can be inserted, the leg massage part including: a connecting frame part; a foot massage part into which a user's foot can be inserted and connected to one side of the connecting frame part; and a calf massage part connected to the other side of the connecting frame part and on which a user's calf can be placed; wherein the foot massage part and the calf massage part are independently movable on the connecting frame part.

[0010] According to the present invention, the foot massage unit and the calf massage unit can move relative to each other in a direction close to each other, a direction spaced from each other, and / or in the same direction on the connecting frame unit, and can be driven separately, thereby increasing the hip joint stretching effect in the minimum extension state and increasing the leg length in the maximum extension state to increase the stretching effect.

[0011] In addition, since the volume of the deformable body expands or contracts as the foot massage part and the calf massage part move relative to each other on the connecting frame, the calf massage part can maintain its position for a certain period of time even when the foot massage part is separated and lowered while the calf massage part is raised, and there is an effect of increasing the stretching range to the maximum extension state.

[0012] Additionally, since one side of the sole lifting part can be raised and lowered, the ankle stretching effect can be increased when rising.

[0013] Additionally, as the sole lift rises, users with relatively short legs can receive a foot massage by having their soles come into contact with the sole lift.

[0014] 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.

[0149] Referring to FIGS. 10 to 13, the movement guide unit (2131) provides a movement path for the foot massage unit (2200) and the calf massage unit (2300), so that the foot massage unit (2200) and the calf massage unit (2300) can move on the movement guide unit (2131).

[0150] Specifically, a guide groove (not shown in the drawing) can be formed in the shape of a groove along the longitudinal direction (up-down direction based on FIG. 10) in the moving guide part (2131), and the leg massage part (2000) and the calf massage part (2300), which will be described later, can move on the moving guide part (2131) along the guide groove.

[0151] Referring to FIGS. 10 to 13, a plurality of moving guide parts (2131) according to one embodiment of the present invention may be provided, and specifically, a pair may be provided. The plurality of moving guide parts (2131) may be arranged on both sides of the widthwise central portion of the connecting frame body (2130).

[0152] From another perspective, a plurality of moving guide parts (2131) can be arranged on both sides of the longitudinal (up-down direction based on FIG. 10) central axis of the connecting frame body (2130).

[0153] A guide groove can be formed on each of a plurality of moving guide parts (2131), and the foot massage part (2200) and the calf massage part (2300) can move on a plurality of moving guide parts (2131) that are spaced apart from each other and parallel to each other along a preset moving direction central axis (AX2).

[0154] A plurality of moving guide parts (2131) are coupled to a hinge shaft (2100), and since the position of the rotation center axis (AX1) of the hinge shaft (2100) is fixed, the positions of the plurality of moving guide parts (2131) can also be fixed.

[0155] When the connecting frame part (2100) rotates by receiving power from the hinge drive part (2700), the plurality of moving guide parts (2131) and the hinge shaft (2100) to which the plurality of moving guide parts (2131) are combined can rotate clockwise and / or counterclockwise with respect to the rotation center axis (AX1).

[0156] Referring to FIGS. 10 to 13, a support member (2135) according to one embodiment of the present invention is formed to extend along the longitudinal direction (upper and lower direction based on FIG. 10) and is connectable with a hinge shaft (2100).

[0157] The support member (2135) can receive power from the outside to rotate the hinge shaft (2100). Specifically, the support member (2135) can come into contact with the hinge driving member (2700) to be described later, and as the hinge driving member (2700) is driven, the position can be changed by receiving power from the hinge driving member (2700).

[0158] According to one embodiment of the present invention, the support member (2135) has a predetermined area and can be in surface contact with the hinge driving member (2700).

[0159] The hinge drive unit (2700) can transmit power to a predetermined area on the support unit (2135), and the support unit (2135) can rotate around the longitudinal central axis of the hinge shaft (2100) as the rotational center axis (AX1).

[0160] As the support member (2135) receives power from the hinge drive member (2700) and rotates, the hinge shaft (2100) coupled to the support member (2135) can rotate clockwise and / or counterclockwise with respect to the rotation center axis (AX1).

[0161] From another perspective, as the hinge shaft (2100) rotates, the connecting frame part (2100) and the foot massage part (2200) and calf massage part (2300) coupled to the connecting frame part (2100) rotate around the longitudinal central axis (AX1) of the hinge shaft (2100) as the rotational center axis, and the leg angle of the user using the massage device (100) can be adjusted.

[0162] That is, the leg massage part (2000) connected to the frame part (1100) rotates around the longitudinal central axis (AX1) of the hinge shaft (2100) as the rotational center axis, and the angle of the user's legs can be adjusted.

[0163] According to one embodiment of the present invention, a support member (2135) may be coupled with a deformation member (2500), specifically a first fixing member (2531), which will be described later, while being fixed in position. The connection between the support member (2135) and the deformation member (2500) will be described in detail later.

[0164] Referring to FIG. 6, FIG. 7a to FIG. 7c, and FIG. 8, a stopper part (2150) according to one embodiment of the present invention can be coupled to a connecting frame body (2130), specifically, a moving guide part (2131). The stopper part (2150) is positioned on a moving path of a first moving part (2270) to be described later, and can restrict the movement of the first moving part (2270).

[0165] Referring to FIG. 7c and FIG. 8, the stopper part (2150) can be placed on the inside of the moving guide part (2131) and can be penetrated and fastened to the moving guide part (2131).

[0166] Referring to FIG. 8, the stopper part (2150) may be formed of a bolt, but is not limited thereto, and a predetermined area may be located inside the movement guide part (2131), and may be formed of various materials within the technical concept of being able to limit the movement of the first movement part (2270).

[0167] Referring to Fig. 8, a first moving part (2270) that is movable on a moving guide part (2131) may be formed with a first moving groove part (2271) having a preset depth along a moving direction central axis (AX2). A stopper part (2150) may be located on the inside of the first moving groove part (2271) formed on the first moving part (2270).

[0168] Accordingly, when the first moving part (2270) moves inside the moving guide part (2131), the stopper part (2150) can come into contact with one end (the upper end as shown in FIG. 8) of the first moving home part (2271).

[0169] Referring to FIG. 7c and FIG. 8, the foot massage part (2200) moves from the upper side to the lower side (as shown in FIG. 8) along the movement center axis (AX2) with respect to the connecting frame part (2100), but since one end (the upper end as shown in FIG. 8) of the first movement groove part (2271) formed on the first movement part (2270) comes into contact with the stopper part (2150), movement of the first movement part (2270) in one direction (as shown in FIG. 8) can be restricted.

[0170] Looking at this from another perspective, the foot massage part (2200) moves in the direction of increasing the length of the user's leg with respect to the connecting frame part (2100) in which the rotational center axis (AX1) of the hinge shaft (2100) is fixed in position, and the position in which the longest extension state is achieved means the position where the first moving part (2270) comes into contact with and hangs over the stopper part (2150) (see FIG. 7c).

[0171] Referring to FIG. 6, FIG. 7a to FIG. 7c and FIG. 10, a foot massage unit (2200) according to one embodiment of the present invention can be connected to a connecting frame unit (2100) into which a user's foot can be inserted.

[0172] Specifically, the foot massage unit (2200) can reciprocate along the central axis (AX2) in a preset movement direction (up-down direction based on FIG. 10) on the connecting frame unit (2100).

[0173] A foot massage unit (2200) according to one embodiment of the present invention may include a foot massage main body unit (2210), a rotation guide unit (2230), a first main body frame (2250), and a first moving unit (2270).

[0174] Referring to FIGS. 6, 7a, 7c, and 10, a foot massage body (2210) according to one embodiment of the present invention is inserted into a user's foot and can be combined with a first body frame (2250) to be described later.

[0175] According to one embodiment of the present invention, the foot massage main body (2210) is formed in a single shape, but is not limited thereto, and as an optional embodiment, the foot massage main body (2210) can be divided into a plurality of regions that can move relative to each other along the direction of movement on the connecting frame (2100).

[0176] As an optional embodiment, the foot massage body (2210) may include a plurality of foot massage bodies (not shown in the drawing) that can move independently of each other.

[0177] Specifically, the foot massage main body (2210) may include a first foot massage main body and a second foot massage main body. The first foot massage main body and the second foot massage main body may move toward each other, away from each other, and / or in the same direction on the connecting frame part (2100).

[0178] In other words, each foot massage body can independently move upward and / or downward through a connecting drive unit corresponding to each foot massage body.

[0179] Additionally, the first foot massage body and the second foot massage body can move in the same direction on the connecting frame (2100) or in opposite directions.

[0180] This allows for various modifications, such as adjusting the position of the user's foot area, adjusting the distance between the first foot massage unit and the second foot massage unit, and providing the user with a stretching function.

[0181] However, it is not limited to this, and the foot massage main body (2210) can be implemented in various modifications, such as including three or more foot massage main bodies.

[0182] A foot massage main body (2210) according to one embodiment of the present invention may include a foot massage base (2211), a sole lifting unit (2213), and an lifting drive unit (2215).

[0183] Although not shown in the drawing, the foot massage main body (2210) may include a foot massage main body housing (drawing symbol not set) that covers the foot massage base (2211), the sole lifting part (2213), and the lifting drive part (2215) and forms the exterior of the foot massage main body (2210).

[0184] An entry hole (drawing symbol not set) may be formed on one side (upper side based on Fig. 6) of the foot massage body housing so that the user's foot can enter, and the user's foot passing through the entry hole may be placed on the foot sole lifting part (2213).

[0185] According to one embodiment of the present invention, a foot massage base (2211) can be formed on the lower side of a foot massage main body (2210), and a foot sole lifting part (2213), a lifting drive part (2215), and a rotation guide part (2230) can be arranged.

[0186] The foot massage base (2211) is coupled with the first main body frame (2250) to be described later, and can move together when the first moving part (2270) coupled with the first main body frame (2250) moves on the connecting frame part (2100), specifically, the moving guide part (2131).

[0187] Referring to FIGS. 6, 7a, and 10, a sole lifting member (2213) according to one embodiment of the present invention accommodates a user's foot and is capable of being raised and lowered on one side. The sole lifting member (2213) may be placed on a foot massage base (2211).

[0188] According to one embodiment of the present invention, a foot lift unit (2213) has one side that can be lifted and the other side opposite thereto can be rotatably coupled to a foot massage base (2211).

[0189] In this specification, ‘one side’ of the sole lifting part (2213) refers to the area where the user’s heel is located, and ‘the other side’ refers to the area where the user’s toes are located.

[0190] The other side of the sole lifting part (2213) can be rotatably connected along a rotation center axis (AX3) preset to the foot massage base (2211).

[0191] One side of the sole lifting unit (2213) can be raised or lowered as the lifting drive unit (2215) to be described later is driven, and specifically, when one side of the sole lifting unit (2213) is raised, the other side can be rotated counterclockwise (based on FIG. 7b) with respect to the rotation center axis (AX3).

[0192] Conversely, when one side of the sole lifting unit (2213) is lowered as the sole lifting unit (2213) is driven, the other side can be rotated clockwise (based on FIG. 7b) with respect to the rotation center axis (AX3).

[0193] A foot massage module that provides a massage function to the user's feet may be installed in the footrest (2213). Specifically, a space that can accommodate the user's feet and wrap around the user's feet may be formed, and the foot massage module may be installed in the space.

[0194] In the present invention, one side of the sole lifting member (2213) where the user's heel is positioned can be raised and lowered, but this is not limited to this, and various modifications are possible, such as the other side where the user's toes are positioned can be raised and lowered, or both sides can be raised and lowered.

[0195] As an optional embodiment, a pressure sensor (not shown in the drawing) may be placed on the sole lifting member (2213). The pressure sensor may measure pressure applied to a preset area on the sole lifting member (2213), for example, an area where the user's heel touches.

[0196] Accordingly, if the preset pressure in the above area is not measured while the leg massage unit (2000) is operating, it is determined that the user's heel is not touching the sole lifting unit (2213), and information about this can be transmitted to the control unit (1200).

[0197] The control unit (1200) can control the operation of the air supply unit so that gas can be supplied to the lift drive unit (2215), specifically, the air cell, by transmitting an electrical signal to the air supply unit.

[0198] This has the effect of allowing a user with relatively short leg length to sit on the massage device (100) so that even if the heel does not touch the sole lifting part (2213), the area can be raised by the lifting drive part (2215) to touch it.

[0199] In the following description, it will be explained based on the assumption that one side where the user's heel is positioned can be raised and lowered, and the opposite side can be rotatably connected to the foot massage base (2211).

[0200] Referring to FIGS. 7A to 7C, a lifting drive unit (2215) according to one embodiment of the present invention is disposed between a foot massage base (2211) and a sole lifting unit (2213), and can raise and lower the sole lifting unit (2213).

[0201] According to one embodiment of the present invention, the lift drive unit (2215) can change shape and volume as it is driven.

[0202] An elevator drive unit (2215) according to one embodiment of the present invention may include an air cell. The elevator drive unit (2215) has a hollow interior and can expand or contract as gas is supplied or discharged from an external air supply unit.

[0203] Referring to Fig. 7a, when the lifting drive unit (2215), specifically the air cell, is in a contracted state, one side of the sole lifting unit (2213) does not rise, and the other side opposite to this does not rotate, and the user's foot is placed on the ground.

[0204] Referring to FIGS. 7b and 7c, when gas is supplied from the air supply unit and the lifting drive unit (2215), specifically, the air cell is inflated, one side of the sole lifting unit (2213) where the user's heel is located is raised, and the other side opposite thereto is rotated counterclockwise (based on FIG. 7b) with respect to the rotation center axis (AX3) so that the user's instep area is stretched, thereby providing an ankle stretching function.

[0205] As the gas is discharged from the air cell, the lift drive unit (2215) contracts again, and one side of the raised sole lift unit (2213) can be lowered again and returned to the reference position shown in Fig. 7a.

[0206] As an optional embodiment, the lift drive unit (2215`) may be an actuator with adjustable length.

[0207] FIGS. 15A and 15B are partial side views illustrating the driving state of an elevator drive unit according to another embodiment of the present invention. Referring to FIGS. 15A and 15B, an elevator drive unit (2215`) according to another embodiment of the present invention can be connected to a footrest elevator unit (2213`), specifically, a tilting base (2213`a).

[0208] Referring to FIGS. 15a and 15b, the sole lifting part (2213`), specifically the tilting base (2213`a), can rotate clockwise and / or counterclockwise based on a preset rotation center axis (AX3`) formed on the upper side of the foot massage base (2211`).

[0209] The lifting drive unit (2215`) can be connected to a connection area (2216`) spaced apart from the rotation center axis (AX3`) of the tilting base (2213`a) on the tilting base (2213`a). Accordingly, as the lifting drive unit (2215`) is driven, the tilting base (2213`a) can receive power from the lifting drive unit (2215`) and rotate relative to the rotation center axis (AX3`).

[0210] As the tilting base (2213`a) rotates, the foot lift unit (2213`) on which the user's foot is placed can rotate.

[0211] Unlike the sole lifting unit (2213) according to one embodiment of the present invention, which receives power from the lifting drive unit (2215) to raise and / or lower an area corresponding to the user's heel, the sole lifting unit (2213') according to another embodiment of the present invention can raise and / or lower an area corresponding to the user's toes.

[0212] Referring to FIGS. 15a and 15b, a lifting drive unit (2215`) according to another embodiment of the present invention may have one side connected to a tilting base (2213`a) and the other side connected to a first main body frame (2250`).

[0213] Referring to FIGS. 15a and 15b, at least one roller that can come into contact with the sole of the user's foot can be rotatably installed on the tilting base (2213`a).

[0214] However, it is not limited thereto, and various modifications are possible, such as the tilting base (2213`a) illustrated in FIGS. 15a and 15b does not have a roller installed, the tilting base (2213`a) is positioned on the outside and / or inside of the sole lifting unit (2213) according to an embodiment of the present invention illustrated in FIGS. 7a to 7c, and rotates and / or tilts based on a rotation center axis (AX3`) different from the rotation center axis (AX3) of the sole lifting unit (2213).

[0215] That is, as the lifting drive unit (2215) according to one embodiment of the present invention is driven, one side (the area corresponding to the user's heel) of the sole lifting unit (2213) is raised and lowered, and independently, as the lifting drive unit (2215`) according to another embodiment of the present invention is driven, the tilting base (2213`a) is rotated and the other side (the area corresponding to the user's toes) is raised and lowered, and the user's ankle can be tilted.

[0216] Referring to FIG. 6, FIG. 7a, and FIG. 10, a rotation guide part (2230) according to one embodiment of the present invention guides the lifting path of the sole lifting part (2213) and can be coupled to the foot massage main body part (2210).

[0217] Referring to Fig. 6, the rotation guide part (2230) can be positioned and fixed on the side of the foot massage base (2211). A plurality of rotation guide parts (2230) can be provided, and can be positioned and fixed on the foot massage base (2211) so that they can be placed on both sides of the sole lifting part (2213).

[0218] Referring to FIGS. 7A to 7C, a rail portion (2231) may be formed through the rotation guide portion (2230) to provide a rotation path for the sole lifting portion (2213). A protrusion (2214) may be formed to protrude outward on one surface of the sole lifting portion (2213) facing the rotation guide portion (2230).

[0219] The protrusion (2214) is located on the inner side of the rail portion (2231) formed in the rotation guide portion (2230) and can come into contact with the rail portion (2231).

[0220] When the lifting drive unit (2215) is driven by the rail unit (2231) formed on the rotation guide unit (2230), the protrusion unit (2214) formed on the sole lifting unit (2213) can move along the rail unit (2231) when the one side of the sole lifting unit (2213) is raised and lowered, and there is an effect of providing a rotation path so that the sole lifting unit (2213) can be stably rotated based on the rotation center axis (AX3).

[0221] Referring to FIG. 6, FIG. 7a to FIG. 7c, a rail portion (2231) formed in a rotation guide portion (2230) according to one embodiment of the present invention may be formed in the shape of a hole portion penetrating the rotation guide portion (2230).

[0222] However, it is not limited to this, and various modifications are possible, such as forming a groove shape within the technical concept that can provide a rotation path of the sole lifting portion (2213) as the protrusion (2214) formed on the sole lifting portion (2213) moves along the rail portion (2231).

[0223] Referring to FIG. 6, FIG. 7a to FIG. 7c and FIG. 10, the first main body frame (2250) according to one embodiment of the present invention can be combined with a foot massage main body (2210), specifically, a foot massage base (2211).

[0224] The first main body frame (2250) can be coupled with the first moving part (2270), and can move together with the first moving part (2270) as the first moving part (2270) moves on the connecting frame part (2100), specifically, the moving guide part (2131).

[0225] The first moving part (2270) is movable on the connecting frame part (2100) via the connecting drive part (2400). That is, the first moving part (2270) is movable on the connecting frame part (2100) by the power generated from the connecting drive part (2400).

[0226] The first moving part (2270) and the first main body frame (2250) can reciprocate along the moving direction central axis (AX2).

[0227] Referring to FIG. 7b, the massage device (100) according to one embodiment of the present invention, specifically, the leg massage unit (2000), illustrates a state in which the user's leg length is at a minimum, and the movement path of the first main body frame (2250) and the movement direction central axis of the second main body frame (2330) provided in the calf massage unit (2300) to be described later can be formed parallel.

[0228] Referring to FIG. 7b, when the foot massage unit (2200) according to one embodiment of the present invention pushes and moves the calf massage unit (2300) upward (based on FIG. 7b), the first main body frame (2250) may be spaced apart from the second main body frame (2330) without coming into contact with it.

[0229] This prevents collision between the first body frame (2250) and the second body frame (2330), and prevents damage to the foot massage part (2200) and the calf massage part (2300) due to the collision.

[0230] As an optional embodiment, when the foot massage unit pushes and moves the calf massage unit (2300) upward (based on FIG. 7b), one end (upper end based on FIG. 7b) of the first main body frame (2250) may be in contact with one end (lower end based on FIG. 7b) of the second main body frame (2330) facing it.

[0231] In this case, as the contact area between the first main body frame (2250) and the second main body frame (2330) increases, the foot massage part (2200) has the effect of stably moving the calf massage part (2300).

[0232] Referring to FIGS. 6, 7a, 8 to 10, a first moving part (2270) according to one embodiment of the present invention is coupled to a first main body frame (2250) and is movable on a connecting frame part (2100), specifically, a moving guide part (2131).

[0233] Referring to FIG. 8 and FIG. 9, the first moving part (2270) is formed to extend along the longitudinal direction (upper and lower direction based on FIG. 8), and a plurality of moving grooves can be formed along the longitudinal direction.

[0234] The first moving groove (2271) has a predetermined depth along the length direction of the first moving groove (2270) and can be formed in the shape of a groove.

[0235] On the inside of the first moving home part (2271), a stopper part (2150) coupled to the connecting frame body (2130), specifically the moving guide part (2131), can be located.

[0236] When the first moving part (2270) moves on the moving guide part (2131), a stopper part (2150) is positioned on the inside of the first moving home part (2271). As shown in FIG. 7c, when the foot massage part (2200) is in the maximum extension state where it is the furthest away from the calf massage part (2300), the stopper part (2150) comes into contact with one end (the upper end as shown in FIG. 8) of the first moving home part (2271), thereby restricting the first moving part (2270) from moving further away from the moving guide part (2131).

[0237] Referring to FIGS. 8 and 9, a second moving groove (2272) may be formed parallel to the first moving part (2270) in the same direction as the longitudinal direction of the first moving groove (2271). The second moving groove (2272) is formed to have a predetermined depth, and a side of the moving guide part (2131) may be placed on the inside of the second moving groove (2272).

[0238] Referring to FIG. 9, the second moving home portion (2272) can be formed on each side of the longitudinal central axis of the first moving portion (2270), and the two sides of the moving guide portion (2131) can be respectively hung on each of the second moving home portions (2272).

[0239] That is, both sides of the moving guide part (2131) cover the upper area (based on FIG. 9) of the first moving part (2270) where the first moving groove part (2271) is formed, and by spanning the second moving groove part (2272), there is an effect that the first moving part (2270) can move stably on the moving guide part (2131).

[0240] Referring to Fig. 9, the second moving groove (2272) formed to extend along the longitudinal direction may include a first section (2272a) and a second section (2272b). The width of the second moving groove (2272) may be formed differently in the first section (2272a) and the second section (2272b).

[0241] That is, the thickness of one end (lower end based on FIG. 9) of the first moving part (2270) where the second moving home part (2272) is formed can be formed as t1 in the first section (2272a), and can be formed as t2, which is relatively thinner than t1, in the second section (2272b).

[0242] Since the thickness of one end of the first moving part (2270) where the second moving groove (2272) is formed along the longitudinal direction of the first moving part (2270) is formed differently, the movement range of the first moving part (2270) can be limited.

[0243] However, it is not limited to this, and various modifications can be implemented, such as the second moving home part (2272) forming the same width along the length direction of the first moving part (2270).

[0244] Referring to FIG. 9, a first moving part (2270) according to one embodiment of the present invention has a first moving groove (2271) formed on one side (upper side as of FIG. 9) so that a stopper part (2150) can be positioned therein, and second moving grooves (2272) formed extending along the length direction on both sides of the other side (lower side as of FIG. 9) so as to surround and hang over the one side, so that the first moving part (2270) can be formed in a 'D' shape when viewed from the front.

[0245] Due to this, the second moving home part (2272) can be hung on both sides of the moving guide part (2131) so that the first moving part (2270) can move stably, and one end (upper end as shown in FIG. 8) of the first moving home part (2271) can be hung on the stopper part (2150), so that the moving range of the first moving part (2270) can be effectively limited.

[0246] Referring to FIGS. 12 and 13, the first moving part (2270) can be in contact with the second moving part (2350) provided in the calf massage part (2300). Specifically, the second moving part (2350) can be placed on the moving path of the first moving part (2270).

[0247] Fig. 12 illustrates a state in which the first moving part (2270) moves and comes into contact with the second moving part (2350), and Fig. 13 illustrates a state in which the first moving part (2270) in Fig. 12 additionally moves and moves the second moving part (2350) upward (based on Fig. 13).

[0248] The second moving part (2350) can receive power from the first moving part (2270) and move until it comes into contact with the upper part (based on FIG. 13) of the connecting frame body (2130).

[0249] Due to this, the second main body frame (2330) coupled with the second moving part (2350) and the calf massage main body part (2310) coupled with the second main body frame (2330) can rise to the upper side of the hinge shaft (2100) (based on FIG. 13).

[0250] Referring to FIG. 7b, when the first moving part (2270) is in contact with the second moving part (2350), the second moving part (2350) is moved to the upper part of the connecting frame body (2130), so that the upper part of the second frame body (based on FIG. 7b) to which the calf massage body body (2310) is coupled can be moved to a position that is higher by a predetermined height (d1) than the reference line (BL) where the rotation center axis (AX1) of the hinge shaft (2100) is located.

[0251] This has the effect of increasing the stretching range by pulling the user's leg as far as possible toward the user's body during hip stretching.

[0252] Referring to FIG. 7a and FIG. 12, the first moving part (2270) is shown in a state in which it is in contact with the second moving part (2350), but the first moving part (2270) has not yet pushed and moved the second moving part (2350).

[0253] At this time, the second main body frame (2330) coupled with the second moving part (2350) is positioned below the reference line (BL) where the rotation center axis (AX1) of the hinge shaft (2100) is located, and this is defined as the 'reference state' in this specification.

[0254] Referring to FIG. 7b, in the reference state, the foot massage unit (2200) moves in a direction approaching the calf massage unit (2300), and the foot massage unit (2200) pushes the calf massage unit (2300) so that the calf massage unit (2300), specifically the upper part of the second main body frame (2330), is positioned higher than the hinge shaft (2100) (based on FIG. 7b), which is defined as a 'minimum extension state' in this specification.

[0255] Referring to Fig. 7c, in the state of Fig. 7b, the foot massage part (2200) is moved in a direction away from the calf massage part (2300) (from the upper side to the lower side based on Fig. 7c), and this is defined as the 'longest extension state' in this specification.

[0256] Referring to FIG. 7b and FIG. 7c, in the minimum extension state and the maximum extension state, the control unit (1200) can transmit an electric signal to the air supply unit to supply gas to the foot massage unit (2200), specifically, the lifting drive unit (2215).

[0257] As the air cell expands, one side of the sole lifting unit (2215), specifically the sole lifting unit (2213) where the user's heel is placed, rises, and the other side opposite to this can rotate around the rotational center axis (AX3).

[0258] At this time, the protrusion (2214) formed on the sole lifting member (2213) moves along the rail member (2231) formed on the rotation guide member (2230), thereby enabling the sole lifting member (2213) to rotate along a preset rotation path.

[0259] As an optional embodiment, the second moving part (2350) can move on the connecting frame part (2100) through the deformation part (2500; driving part). Specifically, the second moving part (2350) can move upward and / or downward on the connecting frame part (2100) through a change in the length between one end and the other end of the driving body.

[0260] Referring to FIGS. 6, 7a, 10 to 13, a calf massage unit (2300) according to one embodiment of the present invention is connected to the other side opposite to one side of a connecting frame unit (2100) to which a foot massage unit (2200) is connected, so that a user's calf can rest thereon.

[0261] The calf massage part (2300) is movable on the connecting frame part (2100), and can move relative to the foot massage part (2200) on the connecting frame part (2100) in a direction approaching each other, a direction away from each other, and / or in the same direction.

[0262] From another perspective, the calf massage unit (2300) and the foot massage unit (2200) can be operated separately.

[0263] This allows the hip joint stretching effect to be increased in the minimum extension state as shown in Fig. 7b, and the leg length to be increased in the maximum extension state as shown in Fig. 7c, thereby increasing the stretching effect.

[0264] In addition, referring to FIGS. 7b and 7c, the calf massage unit (2300) and the foot massage unit (2200) can transmit power to the sole lifting unit (2213) while moving relative to each other on the connecting frame unit (2100) to raise one side of the sole lifting unit (2213), specifically, the area where the user's heel is located. In other words, the ankle stretching effect can be increased by stretching the instep outward.

[0265] As an optional embodiment, the sole lifting unit (2213) can be modified in various ways, such as independently lifting one side where the user's heel is located, even when in the reference state, as shown in FIG. 7a.

[0266] Referring to FIG. 6, FIG. 7a, and FIG. 10, a calf massage unit (2300) according to one embodiment of the present invention may include a calf massage main body (2310), a second main body frame (2330), and a second moving unit (2350).

[0267] The calf massage main body (2310) can be formed in a shape that surrounds the calf, on which the user's leg, specifically the calf, can rest. A massage module (not shown in the drawing) can be placed on the inner surface of the calf massage main body (2310) positioned on the outer side of the user's calf, and can provide a massage function to the user.

[0268] According to one embodiment of the present invention, the calf massage main body (2310) is formed in a single shape, but is not limited thereto, and as an optional embodiment, the calf massage main body (2310) can be divided into a plurality of regions that can move relative to each other along the direction of movement on the connecting frame (2100).

[0269] As an optional embodiment, the calf massage body (2310) may include a plurality of calf massage bodies (not shown in the drawing) that can move independently of each other.

[0270] Specifically, the calf massage main body (2310) may include a first calf massage main body and a second calf massage main body. The first calf massage main body and the second calf massage main body may move toward each other, away from each other, and / or in the same direction on the connecting frame part (2100).

[0271] In other words, each calf massage body can independently move in the upper and / or lower direction of each calf massage body through a driving unit corresponding to each calf massage body.

[0272] Additionally, the first calf massage body and the second calf massage body can move in the same direction on the connecting frame (2100) or in opposite directions.

[0273] This allows for various modifications, such as adjusting the position of the user's calf area, adjusting the distance between the first calf massage body and the second calf massage body, and providing the user with a calf stretching function.

[0274] However, it is not limited to this, and the calf massage main body (2310) may of course include three or more calf massage main bodies.

[0275] Referring to FIGS. 7A to 7C and FIG. 10, a second main body frame (2330) according to one embodiment of the present invention can be coupled to a calf massage main body (2310) on one side (the front side as shown in FIG. 6), and coupled to a second moving part (2350) on the other side opposite thereto (the rear side as shown in FIG. 6).

[0276] The second main body frame (2330) and the calf massage main body (2310) can move together as the second moving part (2350) moves on the connecting frame part (2100), specifically, the connecting frame main body (2130).

[0277] According to one embodiment of the present invention, the second moving part (2350) can move while making surface contact with the inner surface of the connecting frame part (2100). Since the second moving part (2350) makes surface contact with the connecting frame part (2100), specifically the connecting frame body (2130), on both sides, it has the effect of being able to move stably.

[0278] The second moving part (2350) according to one embodiment of the present invention may be formed of polyoxymethylene (POM) material, but may be formed of various materials such as metal or plastic within the technical concept of being movable on the connecting frame body (2130) while being fixedly connected to the second main body frame (2330).

[0279] A deformation part (2500), specifically a second fixed part (2535) to be described later, can be combined with the second main body frame (2330), and as the second main body frame (2330) moves, the second fixed part (2535) can move together.

[0280] Referring to FIG. 12 and FIG. 13, when the first moving part (2270) is in contact with the second moving part (2350), the second moving part (2350) can be pushed up in the direction of the hinge shaft (2100), and as the second moving part (2350) moves, the second fixed part (2535) coupled to the second main body frame (2330) also moves together.

[0281] The modified body (2510) to be described later has one side (lower side as of FIG. 12) connected to a first fixing part (2531) that is fixed to a connecting frame part (2100), specifically, a connecting frame body (2130), and the other side opposite thereto (upper side as of FIG. 12) can be connected to a second fixing part (2535).

[0282] Since the position of the first fixed part (2531) is fixed, as the calf massage part (2300) moves upward (based on FIG. 13), the second fixed part (2535) moves together, and as the second fixed part (2535) and the first fixed part (2531) are separated, the deformable body (2510) located between them can expand.

[0283] The deformable body (2510) may be hollow on the inside and may have a hole (not shown in the drawing) that connects the inside and the outside. Gas may be introduced or discharged through the hole. Accordingly, as shown in FIG. 13, when the second fixing part (2535) is separated from the first fixing part (2531), gas may be introduced into the inside of the deformable body (2510) and cause it to expand.

[0284] Referring to FIG. 7c and FIG. 11, the second moving part (2350) receives power from the first moving part (2270) and moves upward (based on FIG. 11), and then the first moving part (2270) and the foot massage part (2200) including the first moving part (2270) move in a direction away from the calf massage part (2300) (from the upper side to the lower side based on FIG. 7c). Since the gas introduced into the deformable body (2510) is not discharged to the outside, the position of the upper end of the calf massage part (2300) can be maintained at a position higher than the reference line (BL) for a certain period of time.

[0285] Then, as the gas is discharged to the outside from the deformation body (2510), the volume of the deformation body (2510) can be reduced, and the calf massage part (2300) returns to the position where the second moving part (2350) was initially located on the connecting frame body (2130).

[0286] Accordingly, when the upper part (based on FIG. 7c) of the calf massage part (2300) is above the reference line (BL) passing through the rotational center axis (AX1) of the hinge shaft (2100), the leg massage part (2000) can move in a direction away from the calf massage part (2300) (from upper to lower based on FIG. 7c) until the first moving groove (2271) formed in the first moving part (2270) is caught by the stopper part (2150) coupled to the moving guide part (2131), and can have the longest extension state.

[0287] This allows the user to increase leg length while keeping their knees pulled towards their body, thereby increasing the hip joint stretching effect.

[0288] At the same time, the control unit (1200) can drive the air supply unit by transmitting an electrical signal, and supply gas to the lift drive unit (2215) to expand the lift drive unit (2215). As the lift drive unit (2215) expands, one side of the sole lift unit (2213), specifically, an area corresponding to the user's heel, can rise upward (based on FIG. 7c), thereby increasing the ankle stretching effect.

[0289] In addition, in the case of a user whose leg length is relatively short and whose soles do not touch the foot massage main body (2210), specifically the sole lifting unit (2213), one side of the sole lifting unit (2213) corresponding to the area of ​​the user's heel can be raised upward (based on FIG. 7c) to contact the soles of the user's feet, thereby providing a foot massage function.

[0290] As an optional embodiment, the deformable body (2510) is connected to an air supply unit (not shown in the drawing) and can receive gas (e.g., air) from the air supply unit. Specifically, when air is introduced from the air supply unit through a hole formed in the deformable body (2501), the deformable body (2510) can be expanded.

[0291] As a result, while the position of the foot massage unit (2200) is fixed, the calf massage unit (2300) can move away from the foot massage unit (2200) as the deformable body (2510) expands.

[0292] In addition, even if the foot massage part (2200) does not rise toward the user's knees, there is an effect in which the calf massage part (2300) can independently move away from the foot massage part (2200) as the deformable body (2510) expands.

[0293] Referring to FIGS. 7a and 7b, the upper part (based on FIG. 7b) of the second main body frame (2330) provided in the calf massage unit (2300) can be moved to a position higher by a predetermined height (d1) than the reference line (BL) where the rotational center axis (AX1) of the hinge shaft (2100) is located.

[0294] That is, even if the foot massage part (2200) is in contact with the calf massage part (2300) and the calf massage part (2300) is not raised, the position of the calf massage part (2300) is independently raised by supplying gas from the air supply part and inflating the deformable body (2510), thereby providing a stretching function for the hip joint, etc.

[0295] In addition, as the air supply unit is driven, gas can be discharged from the deformable body (2510) through a hole formed in the deformable body (2510), and as the gas is discharged, the deformable body (2510) can contract and its volume can be reduced.

[0296] Accordingly, the calf massage part (2300) can move on the connecting frame part (2100), specifically the connecting frame body (2130), in the direction toward the foot massage part (2200) (from the upper side to the lower side as shown in FIG. 7a).

[0297] Referring to FIG. 6, FIG. 7a to FIG. 7c, FIG. 10, and FIG. 12, a connecting driving unit (2400) according to one embodiment of the present invention can move a foot massage unit (2200) relative to a connecting frame unit (2100).

[0298] Specifically, the connecting frame part (2100), specifically the connecting frame body (2130), is in a state where the rotation center axis (AX1) of the hinge shaft (2100) is fixed to the seat frame (1120), so that the foot massage part (2200) can move relative to the connecting frame part (2100) due to the driving of the connecting drive part (2400).

[0299] Referring to FIG. 7c and FIG. 10, a connecting driving unit (2400) according to one embodiment of the present invention may include a driving source unit (2410), a lead unit (2450), and a block unit (2430).

[0300] Referring to FIG. 7c and FIG. 10, a driving source unit (2410) according to one embodiment of the present invention receives power and generates power, and can be coupled to a foot massage unit (2200), specifically, a foot massage base (2211).

[0301] However, it is not limited to this, and various modifications are possible, such as being combined with a foot massage main body (2210) that is combined with a foot massage base (2211).

[0302] Referring to FIG. 7c and FIG. 10, a lead part (2450) according to one embodiment of the present invention is disposed in a foot massage part (2200), specifically, a foot massage base (2211), and is rotatable by receiving power from a driving source part (2410).

[0303] The lead portion (2450) is formed to extend along a longitudinal central axis, and can rotate clockwise and / or counterclockwise with the longitudinal central axis as a rotational center axis.

[0304] According to one embodiment of the present invention, the longitudinal central axis of the lead portion (2450) may be formed parallel to the movement central axes of the first moving portion (2270) and the second moving portion (2350).

[0305] Referring to FIG. 7c and FIG. 10, a lead portion (2450) according to one embodiment of the present invention may have screw threads (drawing symbol not specified) formed along the outer circumference, and a block portion (2430) to be described later facing the outer circumference of the lead portion (2450) may have screw grooves formed along the inner circumference.

[0306] Accordingly, when power is transmitted from the connecting drive unit (2400) and the lead unit (2450) rotates around the longitudinal center axis as the rotational center axis, the block unit (2430) is blocked from rotating and is fixed in position to the connecting frame unit (2100), specifically, the connecting frame body (2130), and a screw groove is formed along the inner circumference facing the lead unit (2450), so that the lead unit (2450) and the block unit (2430) can move relative to each other.

[0307] That is, the lead part (2450) is connected by penetrating the block part (2430), and as the lead part (2450) in which a screw thread is formed rotates, the position is fixed, and there is an effect that the lead part (2450) can move in a straight line along a preset direction (up and down direction based on FIG. 10) inside the block part (2430) in which a screw groove is formed on the inner surface.

[0308] Due to this, the lead part (2450) and the foot massage part (2200) coupled to the lead part (2450) can move relative to the connecting frame part (2100).

[0309] Referring to FIG. 7c and FIG. 10, a block portion (2430) according to one embodiment of the present invention is coupled to a connecting frame portion (2100), specifically, a connecting frame body (2130), and is capable of relative movement with a lead portion (2450). The block portion (2430) can be connected to the connecting frame body (2130) so as to surround the lead portion (2450).

[0310] A screw groove may be formed on the inner surface of the block portion (2430) to correspond to the shape of the screw thread formed along the outer surface of the lead portion (2450). The lead portion (2450) may penetrate the block portion (2430) and be connected to the block portion (2430).

[0311] Referring to FIG. 7c and FIG. 10, the block portion (2430) can be positioned and connected to the connecting frame body (2130).

[0312] As a result, power is transmitted from the driving unit (2410) to cause the lead unit (2450) to rotate clockwise and / or counterclockwise. At this time, since the block unit (2430) is fixed in a position that prevents rotation to the connecting frame body (2130), the lead unit (2450) moves relative to the block unit (2430).

[0313] That is, as the lead part (2450) and the block part (2430) move relative to each other, the foot massage part (2200) can move on the connecting frame part (2100).

[0314] The connecting drive unit (2400) according to one embodiment of the present invention receives power generated from the driving source unit (2410) and converts the rotational motion of the lead unit (2450) into linear motion, but is not limited thereto, and various modifications can be implemented, such as transmitting power in a rack-and-pinion gear manner within the technical concept of the foot massage unit (2200) moving relative to the connecting frame unit (2100).

[0315] Referring to FIGS. 10 to 13, a deformation unit (2500; driving unit) according to one embodiment of the present invention is disposed between a connecting frame unit (2100) and a calf massage unit (2300), and transmits power to the calf massage unit (2300) so that the calf massage unit (2300) moves on the connecting frame unit (2100), thereby changing the position of the calf massage unit (2300) with respect to the connecting frame unit (2100).

[0316] For example, the deformation part (2500; driving part) may include a first fixed part (2531), a second fixed part (2535), a deformation body (2510), and / or a driving body (not shown in the drawing).

[0317] The driving body may be an actuator that moves the calf massage part (2300) in an upward and / or downward direction of the calf massage part (2300) on the connecting frame part (2100) by changing the length between one end and the other end of the driving body.

[0318] At this time, similar to the deformation body (2510), one end of the driving body may be connected to the connecting frame part (2100) through the first fixing part (2531), and the other end of the driving body may be connected to the calf massage part (2300) through the second fixing part (2535).

[0319] The deformable body (2510) can change shape when the calf massage part (2300) moves on the connecting frame part (2100), and moves the calf massage part (2300) through the shape change. One side (lower side as of FIG. 12) is connected to the connecting frame part (2100), specifically, the first fixed part (2531) connected to the connecting frame body (2130), and the other side (upper side as of FIG. 12) opposite thereto can be connected to the calf massage part (2300), specifically, the second body frame (2330).

[0320] Accordingly, when the calf massage part (2300), specifically the second main body frame (2330), moves, the second fixed part (2535) coupled with the second main body frame (2330) can move together.

[0321] Referring to FIG. 12 and FIG. 13, when the first moving part (2270) is in contact with the second moving part (2350), the second moving part (2350) can be pushed up in the direction of the hinge shaft (2100), and as the second moving part (2350) moves, the second fixed part (2535) coupled to the second main body frame (2330) also moves together.

[0322] Since the position of the first fixed part (2531) is fixed, as the calf massage part (2300) moves upward (based on FIG. 13), the second fixed part (2535) moves together, and as the second fixed part (2535) and the first fixed part (2531) are separated, the deformable body (2510) located between them can expand.

[0323] The deformable body (2510) may be formed with a hole that connects the inside and outside, and gas may be introduced or discharged through the hole. Accordingly, as shown in FIG. 13, when the second fixed part (2535) is separated from the first fixed part (2531), gas may be introduced into the inside of the deformable body (2510) and cause it to expand.

[0324] Referring to FIG. 11, a deformation body (2510) according to one embodiment of the present invention may have a passage hole (drawing symbol not set) formed so that a connection driving part (2400), specifically a lead part (2450), passes through it.

[0325] This prevents collision between the lead part (2450) and the deformation body (2510), and allows the volume of the deformation body (2510) to expand or contract when the distance between the first fixing part (2531) and the second fixing part (2535) is changed.

[0326] Referring to FIG. 7c and FIG. 11, the second moving part (2350) receives power from the first moving part (2270) and moves upward (based on FIG. 11), and then the first moving part (2270) and the foot massage part (2200) including the first moving part (2270) move in a direction away from the calf massage part (2300) (from the upper side to the lower side based on FIG. 7c).

[0327] In this case, since the gas that has entered the deformation body (2510) is not discharged to the outside, the position of the upper part of the calf massage part (2300) can be maintained at a position higher than the reference line (BL) for a certain period of time.

[0328] Then, as the gas is discharged to the outside from the deformation body (2510), the volume of the deformation body (2510) can be reduced, and the calf massage part (2300) returns to the position where the second moving part (2350) was initially located on the connecting frame body (2130).

[0329] Accordingly, when the upper part (based on FIG. 7c) of the calf massage part (2300) is above the reference line (BL) passing through the rotational center axis (AX1) of the hinge shaft (2100), the leg massage part (2000) can move in a direction away from the calf massage part (2300) (from upper to lower based on FIG. 7c) until the first moving groove (2271) formed in the first moving part (2270) is caught by the stopper part (2150) coupled to the moving guide part (2131), and can have the longest extension state.

[0330] This allows the user to increase leg length while keeping their knees pulled towards their body, thereby increasing the hip joint stretching effect.

[0331] In addition, as the volume of the deformation body (2510) decreases, the calf massage part (2300) can return to the standard state by the gravity of the calf massage body part (2310), so a separate driving part is not required.

[0332] Referring to FIG. 8 and FIG. 10, a length sensor unit (2600) according to one embodiment of the present invention measures the relative movement length between a connecting frame unit (2100) and a foot massage unit (2200), and may include a sensor body (2610) and a sensor board (2650).

[0333] The sensor body (2610) can be fixedly positioned on the connecting frame part (2100), specifically the connecting frame body (2130), and the sensor board (2650) can be installed on the foot massage part (2200) that moves on the connecting frame part (2100), specifically the first body frame (2250).

[0334] The sensor body (2610) can be formed of a magnet, and as the connecting frame part (2100) and the foot massage part (2200) move relative to each other, the distance between the sensor board (2650) and the sensor body (2610) changes, and by detecting the change in the magnetic field resulting from this, the relative movement length between the connecting frame part (2100) and the foot massage part (2200) can be measured, and the change in leg length can be measured.

[0335] The length sensor unit (2600) according to one embodiment of the present invention is formed in a Hall sensor manner, but is not limited thereto, and various modifications such as a touch sensor, a pressure sensor, an infrared sensor, an LED sensor, a photo sensor, and an electrostatic sensor can be implemented within the technical concept of measuring the relative movement length between the connecting frame unit (2100) and the foot massage unit (2200) depending on the measurement position.

[0336] Referring to FIGS. 5a and 5b, a hinge driving unit (2700) according to one embodiment of the present invention is capable of contacting a connecting frame unit (2100), and can transmit power to the connecting frame unit (2100) to rotate the connecting frame unit (2100) around a preset rotation center axis.

[0337] The hinge drive unit (2700) can contact the support unit (2135) formed in the connecting frame unit (2100), specifically the connecting frame body (2130). Power can be transmitted to the support unit (2135) while in surface contact with the support unit (2135).

[0338] Due to this, the connecting frame body (2130) can be rotated by a predetermined angle around the longitudinal central axis (AX1) of the hinge shaft (2100) as the rotational center axis.

[0339] As a result, the foot massage unit (2200) and calf massage unit (2300) connected to the connecting frame unit (2100) rotate together, so that the angle of the leg massage unit (2000) on which the leg of the user using the massage device (100) is positioned can be adjusted.

[0340] As an optional embodiment, a roller (not specified in the drawing symbol) may be placed at one end of a hinge driving part (2700) that can come into contact with a support part (2135) formed in a connecting frame body (2130), and since the roller comes into rolling contact with the support part (2135), there is an effect of reducing friction between the support part (2135) and the hinge driving part (2700).

[0341] Referring to FIGS. 5a and 5b, the hinge drive unit (2700) is an actuator type that can adjust the length in a preset direction, but is not limited thereto, and can be formed in various modifications, such as a motor type within the technical concept of being able to rotate the connecting frame unit (2100) by transmitting power to the support unit (2135) through linear motion.

[0342] Hereinafter, the configuration, operating principle, and effect of a massage device according to another embodiment of the present invention will be described.

[0343] FIG. 14 is a drawing illustrating a second moving part according to another embodiment of the present invention.

[0344] A massage device according to another embodiment of the present invention differs only in the second moving part (2350`) provided in the calf massage part (2300`) with respect to the configuration of the leg massage part (2000), so this will be described in detail.

[0345] The second moving part (2350`) is coupled to the second main body frame (2230) and is movable on the connecting frame part (2100), specifically the connecting frame main body (2130). The second moving part (2350`) may be provided with at least one roller (drawing symbol not set) that is rotatably connected to the second main body frame (2230).

[0346] Since the second moving part (2350`) is in cloud contact with the inner surface of the connecting frame body (2130), there is an effect of reducing friction between the second moving part (2350`) and the connecting frame body (2130).

[0347] A massage device according to another embodiment of the present invention is different from the second moving part (2350) according to one embodiment of the present invention, which is movable while making surface contact with the connecting frame body (2130) in relation to the configuration of the leg massage part (2000), except that a roller is provided. Therefore, the configuration, operating principle, and effects of the connecting frame part (2100), the foot massage part (2200), the connecting driving part (2400), the deformation part (2500), the length sensor part (2600), and the hinge driving part (2700) according to one embodiment of the present invention are the same, and a detailed description thereof will be omitted to the extent that they overlap.

[0348] According to embodiments of the present invention, the massage device (100) can increase the hip joint stretching effect in the minimum extension state and increase the leg length in the maximum extension state, as the foot massage unit (2200) and the calf massage unit (2300, 2300`) can move relative to each other in a direction approaching each other, a direction separating each other, or a direction in the same direction on the connecting frame unit (2100) and can be driven separately.

[0349] In addition, as the foot massage part (2200) and the calf massage part (2300, 2300`) move relative to each other on the connecting frame part (2100), the volume of the deformable body (2510) expands or contracts, so that even if the foot massage part (2200) is separated and lowered while the calf massage part (2300, 2300`) is raised, the position can be maintained for a certain period of time, and there is an effect of increasing the stretching range to the maximum extension state.

[0350] 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.

[0351] 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.
