Description

Massage device with leg internal / external rotation function

[0001] The present invention relates to a massage device having a leg internal / external rotation function, and more particularly, to a massage device capable of providing a user with various exercise postures related to leg massage.

[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] Accordingly, various types of comfortable and relaxing chairs based on human science are being developed and put into practical use.

[0006] There are massage devices that provide a leg massage function by inserting the user's legs into them, but there was a problem in that the massage function was limited because they did not provide a function to spread or narrow the legs based on the midline of the user's body.

[0007] The background technology of the present invention is disclosed in Korean Patent No. 10-2022-0158600 (published on December 1, 2022, title: Massage device including individually driven leg massage unit).

[0008] The problem to be solved by the present invention is to provide a massage device having a leg internal / external rotation function by transmitting power to a pair of rotation frame parts through a leg drive part so that a pair of leg massage bodies into which a user's legs are inserted can rotate with respect to the leg connection frames.

[0009] In addition, the position adjustment unit provides a massage device that can apply various movements related to leg massage to the user by adjusting at least one of the height and angle of the leg massage body.

[0010] 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.

[0011] In order to achieve the above-mentioned purpose, a massage device is provided, comprising: a leg massage unit that provides a massage to a user's legs; the leg massage unit comprising: a pair of rotating frame units each rotatably connected to a leg connection frame; a pair of leg massage bodies that each receive a user's legs and are each hinge-joined to the pair of rotating frame units; and a leg drive unit that transmits power to the rotating frame units to rotate the pair of rotating frame units.

[0012] Other aspects, features and advantages other than those described above will become apparent from the following drawings, claims and detailed description of the invention.

[0013] According to the present invention, the power generated from the leg drive unit can rotate the hinge-coupled rotation frame of the leg massage body relative to the seat frame, specifically, the leg connection frame, thereby providing the user with the leg adduction and / or abduction function.

[0014] Additionally, the power generated from the leg drive unit is transmitted to a pair of rotating frame units, allowing the pair of rotating frame units to rotate in opposite directions.

[0015] In addition, since the connecting member is movable inside the slit formed in the moving part, there is an effect in which the linear motion of the moving part can be converted into the rotational motion of the rotating frame body.

[0016] 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.

[0165] Specifically, the mounting cover (2170) covers the axial bearing (2140) that is mounted on the mounting portion (2111) and can be coupled to the rotating frame body (2110).

[0166] Due to this, the congratulatory sign (2140) can be placed on the mounting portion (2111) while maintaining the rotational center axis, and the rotational center axis can be prevented from being displaced.

[0167] Referring to FIG. 8, in the present invention, the concentric ring (2140) is positionally fixed to a mounting portion (2111) formed on the rotating frame body (2110), and a mounting cover (2170) capable of covering the concentric ring (2140) is posted. However, this is exemplary and various modifications are possible, such as the mounting cover (2170) being excluded.

[0168] Referring to FIGS. 7 to 9, a rotating frame body (2110) according to one embodiment of the present invention may have a rotating shaft portion (2130) to be described later, specifically a shaft body (2131), inserted therein, and the longitudinal central axis of the shaft body (2131) may form a rotational central axis (AX1) of the rotating frame body (2110).

[0169] Referring to FIG. 9, the rotation center axis (AX1) of the rotation frame part (2100) for the bridge connection frame (1121), specifically the rotation frame body (2110), can be positioned at a preset distance from the center of the rotation frame body (2110).

[0170] Specifically, the rotation center axis formed in each of a pair of rotation frame bodies (2110A, 2110B) may be formed to face outward from the center of each rotation frame body (2110A, 2110B).

[0171] That is, referring to FIG. 8, the rotation center axis (AX1) of the rotation frame body (2110) to which the leg massage body (2300A) into which the left leg of the user (10) is inserted is hinge-coupled can be formed at a position spaced apart from the center of the rotation frame body (2110) by a preset distance in the direction approaching the arm massage unit (3000) into which the left arm of the user (10) is inserted.

[0172] Looking at this from another perspective, the rotation center axis of the rotation frame body (2110) into which the leg massage body (2300B) into which the user's (10) right leg is inserted is hinge-coupled can be formed at a position spaced apart from the center of the rotation frame body (2110) by a preset distance in the direction approaching the arm massage unit (3000) into which the user's (10) right arm is inserted.

[0173] This allows the rotation center axis to be formed near the user's (10) buttocks, thereby effectively providing the user's (10) leg adduction and / or abduction function.

[0174] Referring to FIG. 8, at least one fastening hole (2110h) may be formed in the rotating frame body (2110) according to one embodiment of the present invention.

[0175] A rotating shaft portion (2130), specifically a shaft body (2131) to be described later, can be inserted into the rotating frame body (2110), and a fastening hole portion (2131h) formed in the shaft body (2131) and a fastening hole portion (2110h) formed in the rotating frame body (2110) can be connected.

[0176] Although not shown in the drawing, a shaft fastening member such as a bolt can penetrate the rotating frame portion (2100), specifically, the rotating frame body (2110) and the shaft body (2131) through the fastening hole portion (2110h, 2131h) formed in the shaft body (2131) to fasten the rotating frame body (2110) and the shaft body (2131).

[0177] According to one embodiment of the present invention, a plurality of shaft fastening members are provided, and the plurality of shaft fastening members can penetrate and fasten the rotating frame part (2100), specifically the rotating frame body (2110), and the shaft body (2131) at a plurality of points along the central axis in the longitudinal direction (up-down direction based on FIG. 8) of the shaft body (2131).

[0178] Referring to FIG. 8, a connecting hole (2113) may be formed in a rotating frame body (2110) according to one embodiment of the present invention.

[0179] The rotating frame body (2110) and the moving part (2550) can be connected by passing through the connecting member (2150) to be described later through the slit part (2551) formed in the connecting hole part (2113) and the moving part (2550).

[0180] As a result, the power generated from the leg drive unit (2500) is transmitted to the rotating frame body (2110) through the moving unit (2550), and the rotating frame body (2110) can rotate relative to the leg connection frame (1121).

[0181] As the rotating frame body (2110) rotates, the leg massage body (2300) hinge-connected to the rotating frame body (2110) rotates by a preset angle with respect to the leg connection frame (1121), thereby providing the user (10) with leg internal and / or external rotation exercise.

[0182] Referring to FIG. 14, in a rotating frame body (2110) according to one embodiment of the present invention, an extension portion (2115) may be formed to extend in an outward direction. Specifically, the extension portion (2115) may be formed on the bottom surface of the rotating frame body (2110).

[0183] Referring to FIG. 14, the extension (2115) can be positioned opposite the rotation center axis (AX1) for the leg connection frame (1121) based on the center of the rotation frame body (2110).

[0184] When the user (10) is seated on the massage device (100) and the front direction is defined as 'forward', the extension (2115) can be formed to protrude and extend toward the rear side of the rotating frame body (2110).

[0185] Referring to FIG. 9, the bridge drive unit (2500) to be described later may include a frame support unit (2595) that contacts and supports one side of the rotation frame unit (2100). The frame support unit (2595) may contact and support an extension unit (2115) that extends toward the rear side of the rotation frame unit (2100), specifically, the rotation frame main body (2110).

[0186] Since the extension part (2115) is formed to extend toward the rear side of the rotation frame body (2110), even if the rotation frame body (2110) rotates by a preset angle on the leg connection frame (1121), it can be supported by the frame support part (2595) through contact, thereby preventing the rotation frame part (2100) and the leg massage body (2300) from being biased to one side and applying excessive load.

[0187] Referring to FIGS. 8 to 10, a rotary shaft portion (2130) according to one embodiment of the present invention forms a rotational center axis (AX1) of a rotary frame body (2110), and can connect a leg connection frame (1121) and the rotary frame body (2110).

[0188] Referring to Fig. 8, a rotary shaft portion (2130) according to one embodiment of the present invention may include a shaft body (2131), a support member (2137), and a shaft fastening member (not shown in the drawing). The shaft body (2131) is formed to extend along a rotational center axis (AX1) and may be inserted through the rotation frame body (2110).

[0189] Referring to FIG. 8, a rotating frame body (2110) can be rotatably placed on a leg connecting frame (1121), and a shaft body (2131) can be inserted into the rotating frame body (2110) through a frame hole (1121h) formed on the leg connecting frame (1121).

[0190] The support member (2137) is open on both sides and can be formed into a cylindrical shape, surrounds the shaft body (2131), and can be installed in the leg connection frame (1121).

[0191] That is, the support member (2137) can be placed between the shaft body (2131) and the leg connection frame (1121).

[0192] Due to this, the support member (2137) maintains the central axis of the shaft body (2131) and has the effect of stably supporting the rotation of the shaft body (2131) and the rotation frame body (2110).

[0193] Referring to Fig. 8, the outer diameter of one end (the upper end based on Fig. 8) of the support member (2137) can be formed relatively larger than the frame hole (1121h) formed in the leg connection frame (1121).

[0194] Due to this, the support member (2137) can be stably positioned and fixed on the leg connection frame (1121), and has the effect of wrapping around the shaft body (2131) and stably supporting the rotation of the shaft body (2131).

[0195] Referring to FIGS. 8 and 9, a rotating frame body (2110) is placed between frame holes (1121h) formed in the upper and lower portions, specifically, in a region preset in a bridge connecting frame (1121) according to one embodiment of the present invention, and a shaft body (2131) can be inserted through the frame holes (1121h) and the rotating frame body (2110).

[0196] Referring to FIG. 8, a fastening hole (2131h) is formed in a direction perpendicular to the longitudinal central axis in the shaft body (2131), and the fastening hole (2131h) can be communicated with a fastening hole (2110h) formed in the rotating frame body (2110) into which the shaft body (2131) is inserted.

[0197] Accordingly, the shaft fastening member can be fastened by penetrating the fastening holes (2110h, 2131h) formed in the rotating frame body (2110) and the shaft body (2131), respectively, so that the shaft body (2131) and the rotating frame body (2110) can be fastened, and the rotating frame body (2110) can rotate relative to the leg connecting frame (1121) with the longitudinal central axis of the shaft body (2131) as the rotational central axis (AX1).

[0198] Referring to FIG. 9, when the rotation frame body (2110A) to which the leg massage body (2300A) that accommodates the left leg of the user (10) is hinge-coupled rotates counterclockwise (based on FIG. 9) around the rotation center axis (AX1), the massage device (100) can provide a leg abduction function to the user (10).

[0199] Conversely, when the rotating frame body (2110) to which the leg massage body (2300A) that accommodates the left leg of the user (10) is hinge-coupled rotates clockwise (based on FIG. 9) around the rotation center axis (AX1), the massage device (100) can provide the leg adduction function to the user (10).

[0200] Referring to FIG. 8, an extension portion (2132) having a relatively large diameter may be formed at one end (the upper end based on FIG. 8) of the shaft body (2131) according to one embodiment of the present invention.

[0201] Specifically, the outer diameter of the extension portion (2132) can be formed relatively larger than the inner diameter of the support member (2137) and the inner diameter of the frame hole portion (1121h) formed in the leg connection frame (1121).

[0202] This prevents the shaft body (2131) from falling by penetrating the frame hole (1121h) formed in the leg connection frame (1121) or the hole formed in the rotation frame body (2110), and has the effect of maintaining the rotation center axis of the rotation frame body (2110) with respect to the leg connection frame (1121).

[0203] According to one embodiment of the present invention, the expansion portion (2132) is formed integrally with the shaft body (2131), and is formed to have a diameter that is relatively larger than that of a section other than the section where the expansion portion (2132) is formed. However, this is not limited to this, and various modifications are possible, such as forming it as a separate object such as an E-ring and being coupled to the shaft body (2131).

[0204] Referring to FIGS. 7 to 11, a connecting member (2150) according to one embodiment of the present invention connects a rotating frame body (2110) and a leg driving unit (2500), and can transmit power generated from the leg driving unit (2500) to the rotating frame body (2110).

[0205] According to one embodiment of the present invention, a connecting member (2150) is formed in a pin shape and can penetrate and connect the rotating frame body (2110) and the leg driving unit (2500), specifically the moving unit (2550).

[0206] However, it is not limited to this, and various modifications such as bolts are possible within the technical concept of connecting the moving part (2550) and the rotating frame body (2110) so that the rotating frame body (2110) can be moved and / or rotated as the moving part (2550) moves.

[0207] Referring to FIGS. 8 to 10, the connecting member (2150) can connect the rotating frame body (2110) and the moving part (2550) by passing through the connecting hole (2113) formed in the rotating frame body (2110) and the slit (2551) formed at a position overlapping the connecting hole (2113) on the moving part (2550).

[0208] Referring to Fig. 8, the diameter of one end (the upper end as shown in Fig. 8) of the connecting member (2150) can be formed relatively larger than the diameter of the connecting hole (2113) formed in the rotating frame body (2110). As a result, the connecting member (2150) can be hung over the rotating frame body (2110) without a separate fastening member, thereby stably connecting the rotating frame body (2110) and the moving member (2550).

[0209] Referring to FIGS. 9 and 10, a connecting member (2150) according to one embodiment of the present invention transmits linear power generated from a leg drive unit (2500) to a rotating frame body (2110) when the moving unit (2550) moves linearly, thereby converting the linear power into rotational power.

[0210] Referring to FIGS. 10 and 11, a connecting member (2150) according to one embodiment of the present invention may be spaced apart from a rotating shaft portion (2130), specifically a shaft body (2131). The shaft body (2131) is connected to a rotating frame body (2110), penetrates a leg connecting frame (1121), and may form a rotational center axis (AX1) of the rotating frame portion (2100), specifically the rotating frame body (2110).

[0211] At this time, since the connecting member (2150) connecting the rotating frame body (2110) and the moving part (2550) is formed to extend along a central axis (AX2) different from the rotational central axis (AX1) of the rotating frame body (2110), there is an effect that the linear movement of the moving part (2550) can be converted into the rotational movement of the rotating frame body (2110).

[0212] That is, the moving part (2550) is moved linearly by the power generated from the leg drive part (2500), and the linear movement of the moving part (2550) is transmitted to the rotating frame body (2110) through the connecting member (2150), so that the rotating frame body (2110) can be rotated clockwise and / or counterclockwise with the longitudinal central axis of the shaft body (2131) as the rotational center axis.

[0213] As the rotating frame body (2110) rotates, the leg massage body (2300) hinge-joined to the rotating frame body (2110) rotates clockwise and / or counterclockwise with respect to the rotation center axis (AX1) of the rotating frame body (2110).

[0214] In other words, there is an effect in which the user (10) seated on the massage device (100) can perform an external rotation movement in which the legs are spread out to both sides with respect to the center of the leg connection frame (1121) while facing forward, or an internal rotation movement in which the legs are folded back again.

[0215] Referring to FIGS. 10 and 11, a connecting member (2150) according to one embodiment of the present invention is movable within a slit portion (2551) formed in a moving member (2550), and since a space in which the connecting member (2150) can move is formed within the slit portion (2551), there is an effect in which linear movement of the moving member (2550) can be converted into rotational movement of the rotating frame body (2110).

[0216] In relation to the above, the bridge drive unit (2500) will be described in detail later.

[0217] Referring to FIGS. 1, 3, 4, and 14, a leg massage body (2300) according to one embodiment of the present invention accommodates the leg of a user (10) and can be hinge-coupled to a rotating frame part (2100).

[0218] Specifically, a pair of leg massage bodies (2300) are provided to accommodate the left and right legs of the user (10), respectively, and a pair of leg massage bodies (2300A, 2300B) can be hinge-connected to a pair of rotating frame parts (2100A, 2100B), respectively.

[0219] A leg massage unit (2300) according to one embodiment of the present invention can provide a leg massage function to a user (10) and can include at least one of an air cell, a calf massage module (not shown), and a foot massage unit (not shown). As described above, a detailed description thereof will be omitted.

[0220] Referring to FIGS. 4 to 6 and 14, a leg massage body (2300) according to one embodiment of the present invention may include a leg base part (2310). The leg base part (2310) corresponds to a pair of rotating frame bodies (2110), and a pair may be provided.

[0221] Referring to FIG. 5, the bridge base portion (2310) can be hinge-coupled to the rotation frame portion (2100), specifically, the rotation frame body (2110).

[0222] Referring to FIG. 5, a bridge base portion (2310) according to one embodiment of the present invention can be connected to a rotating frame portion (2100) by surrounding a shaft housing (2140) that is mounted on a mounting portion (2111) formed on a rotating frame body (2110).

[0223] As an optional embodiment, when the axial bearing (2140) is fixed in position to a mounting portion (2111) formed in the rotating frame body (2110) through a fastening member (not shown in the drawing), the leg base portion (2310) surrounds the axial bearing (2140) and can rotate clockwise and / or counterclockwise based on a preset rotational center axis, specifically, a longitudinal center axis (AX4 in FIG. 5) of the axial bearing (2140).

[0224] As an optional embodiment, when the pivot shaft (2140) is positionally fixed to the mounting portion (2111) formed in the rotating frame body (2110) through a fastening member (not shown in the drawing), a hinge shaft (not shown in the drawing) formed in the leg base portion (2310) can be inserted through the pivot shaft (2140).

[0225] The hinge shaft can be rotated clockwise and / or counterclockwise with respect to the rotation center axis (AX4) while inserted into the pivot housing (2140), and the leg base part (2310) and the leg massage body (2300) can be rotated relative to the rotation frame part (2100), specifically, the rotation frame body (2110).

[0226] As a result, power is transmitted from the position adjustment unit (2700) to be described later, specifically the angle adjustment unit (2710), so that the leg massage body (2300) performs a hinge movement with respect to the rotation frame unit (2100), thereby having the effect of adjusting the leg angle of the user (10) seated on the massage device (100).

[0227] Although not shown in the drawing, when the axial bearing (2140) is positionally fixed to the mounting portion (2111) formed in the rotating frame body (2110) through a fastening member, the hinge shaft (not shown in the drawing) inserted through the axial bearing (2140) can be inserted to a position spaced apart from the fastening member penetrating the axial bearing (2140).

[0228] This prevents the fastening member and the hinge shaft from interfering with each other, and has the effect of allowing the hinge shaft formed on the leg base portion (2310) to stably rotate relative to the axial bearing (2140) that is fixed in position on the fixing portion (2111).

[0229] Referring to FIGS. 5 and 6, a contact frame (2311) may be formed on one side of a leg base portion (2310) according to one embodiment of the present invention. The contact frame (2311) may be formed on one side (rear side as of FIG. 5) of the leg base portion (2310) facing an angle adjustment portion (2710) to be described later.

[0230] The contact frame (2311) can be formed in a plate shape and can be in contact with the angle adjustment unit (2710), specifically the contact unit (2713).

[0231] By maintaining the contact frame (2311) in contact with the contact portion (2713), power is transmitted from the angle adjustment portion (2710), and the leg massage body (2300) has the effect of being able to hinge around a rotation center axis (AX4) that is preset with respect to the rotation frame portion (2100).

[0232] A leg massage unit (2300) according to one embodiment of the present invention may include at least one of an air cell, a calf massage module (not shown), and a foot massage unit (not shown). A detailed description thereof will be omitted as it has been described above.

[0233] Referring to FIGS. 7 to 13 and 15, a leg drive unit (2500) according to one embodiment of the present invention transmits power to a rotation frame unit (2100) to rotate the rotation frame unit (2100), and may include a drive base unit (2510), a drive source unit (2530), a moving unit (2550), a power transmission unit (2570), a rotation restriction unit (2591), and a frame support unit (2595).

[0234] According to one embodiment of the present invention, a bridge drive unit (2500) can generate linear power to rotate a rotation frame unit (2100).

[0235] Referring to FIG. 7, a leg drive unit (2500) according to one embodiment of the present invention is placed on a leg connection frame (1121) and can generate power to rotate a rotation frame unit (2100) relative to the leg connection frame (1121).

[0236] Specifically, as the rotation frame part (2100) is rotated outward and / or inward relative to the center of the leg connection frame (1121), the leg massage body (2300) coupled to the rotation frame part (2100) can rotate outward and / or inward relative to the center of the leg connection frame (1121).

[0237] That is, the rotation frame part (2100), specifically the rotation frame body (2110) and the leg massage body (2300) coupled to the rotation frame body (2110), can be rotated by a preset angle based on the rotation center axis (AX1) that is perpendicular to the ground on which the massage device (100) is placed.

[0238] A pair of rotating frame parts (2100) and leg massage main body (2300) are provided, and can rotate relative to the leg connection frame (1121) based on different rotational centers.

[0239] According to one embodiment of the present invention, a bridge drive unit (2500) can transmit power to a pair of rotating frame units (2100A, 2100B) to rotate the pair of rotating frame units (2100A, 2100B) in opposite directions.

[0240] As a result, when a pair of rotating frame parts (2100A, 2100B) rotate in opposite directions and rotate outward with respect to the center of the leg connecting frame part (1121), a leg abduction massage function can be provided to a user (10) seated on the massage device (100).

[0241] Conversely, when a pair of rotating frame parts (2100A, 2100B) rotate inwardly based on the center of the leg connecting frame (1121), a leg internal rotation massage function can be provided to a user (10) seated on the massage device (100).

[0242] Referring to FIGS. 7, 9 to 13, the driving base unit (2510) according to one embodiment of the present invention is placed on the leg connection frame (1121) and can be positionally fixed to the leg connection frame (1121).

[0243] A driving source (2530) may be installed in the driving base (2510). The driving base (2510) may be installed in the central portion of the leg connection frame (1121).

[0244] A power transmission unit (2570), a rotation restriction unit (2591), and a frame support unit (2595) to be described later can be installed in the drive base unit (2510), and a detailed description of these will be provided later.

[0245] Referring to FIGS. 5, 7, and 13, a driving source unit (2530) according to one embodiment of the present invention is installed in a driving base unit (2510) and can generate power by receiving power from the outside.

[0246] According to one embodiment of the present invention, the driving source (2530) generates rotational power in a motor manner and transmits the power to the moving part (2550) through the power transmission part (2570), but is not limited thereto, and various modifications are possible, such as generating linear power in an actuator manner.

[0247] According to one embodiment of the present invention, a moving part (2550) is connected to a rotating frame part (2100), and a pair of moving parts may be provided, each connected to a pair of rotating frame parts (2100). The moving part (2550) can move by receiving power from a power transmission part (2570) to be described later.

[0248] A pair of moving parts (2550A, 2550B) can move in opposite directions by receiving power generated from a driving source (2530) from a power transmission part (2570). A pair of moving parts (2550) can move along a preset movement center axis (AX3).

[0249] Referring to FIG. 9, a moving part (2550) according to one embodiment of the present invention may be connected to a power transmission part (2570) on one side and to a rotating frame part (2100) on the other side.

[0250] As a result, the moving part (2550) moves by receiving the power generated from the power transmission part (2570), and as the moving part (2550) moves, the rotating frame part (2100) can rotate relative to the leg connection frame (1121).

[0251] Referring to FIGS. 10 and 11, a slit portion (2551) may be formed on one side of the rotating frame portion (2100), specifically, the moving portion (2550) connected to the connecting member (2150). The slit portion (2551) is formed in the shape of a hole portion, and the connecting member (2150) can pass through it.

[0252] Specifically, the connecting member (2150) provided in the rotating frame part (2100) passes through and spans the rotating frame body (2110) and the slit part (2551), thereby enabling the linear movement of the moving part (2550) to be converted into the rotational movement of the rotating frame body (2110).

[0253] Referring to FIG. 10 and FIG. 11, a slit portion (2551) formed in a moving portion (2550) may be formed such that the length (d1) in the first direction is relatively longer than the length (d2) in the second direction that is perpendicular to the first direction.

[0254] Specifically, the second direction can be formed parallel to the movement direction of the moving part (2550), and the first direction can be formed at a predetermined angle with the movement direction of the moving part (2550).

[0255] Referring to FIG. 10 and FIG. 11, the diameter (2r) of the connecting member (2150) arranged on the inner side of the slit portion (2551) can be formed to be relatively smaller than the length (d1) in the first direction, so that the connecting member (2150) can move in the first direction while in contact with the inner surface of the slit portion (2551).

[0256] That is, since a space in which the connecting member (2150) can move is formed on the inside of the slit portion (2551), there is an effect in which the linear movement of the moving portion (2550) can be converted into the rotational movement of the rotating frame body (2110) while maintaining the center axis of movement (AX3) of the moving portion (2550).

[0257] Referring to FIG. 10, the rotating frame part (2100) is illustrated in a state where it does not rotate relative to the leg connecting frame (1121), and a connecting member (2150) having a central axis (AX2) spaced apart from the rotational central axis (AX1) of the rotating frame part (2100) can come into contact with the inner surface of the front side of the slit part (2551) formed in the moving part (2550).

[0258] Referring to FIG. 11, power generated from a driving source (2530) is transmitted to a moving part (2550) through a power transmission part (2570), and a state in which a rotating frame part (2100) rotates relative to a leg connection frame (1121) is illustrated. As the moving part (2550) moves linearly, power is transmitted to a connecting member (2150) having a region spaced apart from a rotation center axis (AX1) of the rotating frame part (2100) and a center axis (AX2) spaced apart from the rotation center axis (AX1), thereby allowing the rotating frame part (2100) to rotate relative to the leg connection frame (1121).

[0259] At this time, the connecting member (2150) can come into contact with the inner surface on the rear side of the slit portion (2551) formed in the moving portion (2550).

[0260] Referring to FIGS. 7, 9, 10, and 13, a power transmission unit (2570) according to one embodiment of the present invention connects a driving source unit (2530) and a moving unit (2550), and can transmit power generated from the driving source unit (2530) to the moving unit (2550).

[0261] Referring to FIG. 9 and FIG. 13, a power transmission unit (2570) according to one embodiment of the present invention may include a gear unit (2571) and a transmission shaft (2575).

[0262] The gear unit (2571) can come into contact with the driving unit (2530) and receive power from the driving unit (2530).

[0263] The gear unit (2571) may be formed in a worm gear manner. However, it is not limited thereto, and various modifications, such as a rack-and-pinion gear manner, are possible within the technical scope of being able to transmit power from the driving unit (2530).

[0264] The gear unit (2571) according to one embodiment of the present invention can rotate by receiving rotational power generated from the driving source unit (2530). The gear unit (2571) is coupled to a transmission shaft (2575) to be described later, and the transmission shaft (2575) can rotate together as the gear unit (2571) rotates.

[0265] A transmission shaft (2575) according to one embodiment of the present invention is connected to a gear unit (2571), is formed to extend along the longitudinal direction (left-right direction based on FIG. 13), and can rotate together with the gear unit (2571) when the gear unit (2571) rotates by receiving power from the driving source unit (2530).

[0266] Referring to FIG. 9 and FIG. 13, the transmission shaft (2575) can be connected to a pair of moving parts (2550), and the transmission shaft (2575) and the pair of moving parts (2550) can rotate relative to each other.

[0267] A pair of moving parts (2550) can move on a transmission shaft (2575) and receive power from a driving source (2530) so that the power transmission part (2570), specifically the transmission shaft (2575), rotates, thereby allowing a pair of moving parts (2550) to move linearly on the transmission shaft (2575).

[0268] According to one embodiment of the present invention, a transmission shaft (2575) and a pair of moving parts (2550) may be connected by a screw connection. Specifically, a screw thread may be formed on the outer surface of the transmission shaft (2575), and a screw groove may be formed on the inner surface of the moving part (2550) that comes into contact with the outer surface of the transmission shaft (2575).

[0269] As a result, when the transmission shaft (2575) that receives power from the driving unit (2530) through the gear unit (2571) rotates, the transmission shaft (2575) and the moving unit (2550) can rotate relative to each other.

[0270] Referring to FIG. 9, FIG. 12, and FIG. 13, a rotation limiting member (2591) fixed to a driving base member (2510) makes surface contact with one side (lower side based on FIG. 13) of a moving member (2550) while supporting the contact, and the rotation limiting member (2591) can limit the rotation of the moving member (2550).

[0271] As a result, the rotational power of the transmission shaft (2575) is transmitted to the moving part (2550), which has the effect of generating linear power.

[0272] As the power transmission unit (2570) according to one embodiment of the present invention transmits power to a pair of moving units (2550A, 2550B), the pair of moving units (2550A, 2550B) can move in opposite directions.

[0273] That is, as the power transmission unit (2570) according to one embodiment of the present invention, specifically the transmission shaft (2575), rotates, the moving units (2550) connected on both sides with respect to the center of the transmission shaft (2575) can move in opposite directions.

[0274] Referring to FIG. 13, in the initial state where the moving part (2550) is not moving, the power generated from the driving source (2530) moves the moving part (2550) through the power transmission part (2570) at the first position (P1) of the end of the moving part (2550), thereby moving the end of the moving part (2550) to the second position (P2).

[0275] Referring to FIG. 13, when the moving unit (2550) moves from the first position (P1) to the second position (P2), the distance between the pair of moving units (2550A, 2550B) may increase, and when the moving unit (2550) moves from the second position (P2) to the first position, the distance between the pair of moving units (2550A, 2550B) may decrease.

[0276] Looking at this from another perspective, FIG. 10 illustrates a case where the end of the moving part (2550) is at a first position (P1), and FIG. 11 illustrates a case where the end of the moving part (2550) is at a second position (P2).

[0277] That is, as the end of the moving part (2550) moves from the first position (P1) to the second position (P2), power can be transmitted to the rotating frame part (2100), and the rotating frame body (2110) and the leg massage body (2300) hinge-joined to the rotating frame body (2110) can be rotated outward with respect to the center of the leg connection frame (1121) based on the rotation center axis (AX1).

[0278] Conversely, as the end of the moving part (2550) moves from the second position (P2) to the first position (P1), power can be transmitted to the rotating frame part (2100), and the rotating frame body (2110) and the leg massage body (2300) hinge-coupled to the rotating frame body (2110) can be rotated inward with respect to the center of the leg connection frame (1121) based on the rotation center axis (AX1).

[0279] Referring to FIGS. 10 and 11, since the connecting member (2150) is movable inside the slit portion (2551) formed at one end of the moving portion (2550) connected to the rotating frame portion (2100), there is an effect that the linear movement of the moving portion (2550) can be converted into the rotational movement of the rotating frame portion (2100), specifically, the rotating frame body (2110), while maintaining the movement center axis (AX3) of the moving portion (2550).

[0280] According to one embodiment of the present invention, the transmission shaft (2575) may have screw threads formed in opposite directions at the portions respectively connected to a pair of moving parts (2550), and the direction of the screw grooves formed on the inner surface of a pair of moving parts (2550A, 2550B) that come into surface contact with the transmission shaft (2575) may be formed in the same manner.

[0281] Accordingly, when power is transmitted from the driving unit (2530) and the transmission shaft (2575) rotates around the moving center axis (AX3), a pair of moving units (2550A, 2550B) connected to both sides of the transmission shaft (2575) can move in opposite directions.

[0282] However, it is not limited to this, and various modifications are possible, such as forming the direction of the screw threads formed on both sides of the transmission shaft (2575) connected to a pair of moving parts (2550A, 2550B) in the same way, and forming the screw grooves formed on the inner surface of the pair of moving parts (2550A, 2550B) in surface contact with the screw threads formed on the outer surface of the transmission shaft (2575) in opposite directions.

[0283] Referring to FIGS. 7, 9, 12, and 13, a rotation restriction unit (2591) according to one embodiment of the present invention is coupled to a driving base unit (2510), and a plurality of such units may be provided to correspond to a pair of moving units (2550).

[0284] The rotation restriction part (2591) is fixed in position to the driving base part (2510) and can contact and support the moving part (2550).

[0285] Specifically, the rotation restriction part (2591) can be in surface contact with one surface (bottom surface as shown in FIG. 13) of the moving part (2550). Since the rotation restriction part (2591) and the moving part (2550) are in surface contact, the moving part (2550) is restricted from rotating on the rotation restriction part (2591), and the moving part (2550) can move linearly along a preset direction (left and right direction as shown in FIG. 13) by the relative rotation of the moving part (2550) and the power transmission part (2570), specifically, the transmission shaft (2575).

[0286] In the present invention, the rotation restriction part (2591) is arranged on the lower side (based on FIG. 13) of the moving part (2550), but is not limited thereto, and various modifications are possible, such as being arranged on the upper side (based on FIG. 13) of the moving part (2550) within the technical concept of restricting the rotation of the moving part (2550).

[0287] Referring to FIG. 7, FIG. 9, and FIG. 13, a frame support member (2595) according to one embodiment of the present invention is disposed between a driving base member (2510) and a rotation frame member (2100), and can contact-support the rotation frame member (2100).

[0288] The frame support member (2595) can be placed on one surface (upper surface as shown in FIG. 13) of the drive base member (2510) facing the rotation frame member (2100), specifically the rotation frame body (2110), and can contact and support the rotation frame body (2110).

[0289] As an optional embodiment, an area of ​​the frame support portion (2595) that can come into contact with the rotating frame body (2110) may be formed of a rubber material.

[0290] This has the effect of reducing friction and damage caused by friction between the rotating frame body (2110) and the frame support member (2595).

[0291] Referring to FIG. 13, a pair of frame supports (2595) may be provided to correspond to a pair of rotating frame bodies (2110A, 2110B).

[0292] Referring to FIG. 9, the rotation frame body (2110) is supported by the frame support member (2595) on the other side of the center of the rotation frame body (2110) separately from the rotation center axis (AX1) formed on one side based on the center of the rotation frame body (2110), thereby preventing the rotation frame body (2110) to which the leg massage body (2300) is connected from tilting in the up-and-down direction (based on FIG. 4).

[0293] Referring to FIG. 14, since the extension portion (2115) is formed to protrude and extend toward the rear side of the rotation frame body (2110), even when the rotation frame body (2100) is rotated in an outward direction based on the rotation center axis, there is an effect in which the frame support portion (2595) can stably contact and support the rotation frame body (2110).

[0294] Referring to FIGS. 4 to 7 and 15, a position adjustment unit (2700) according to one embodiment of the present invention may include an angle adjustment unit (2710) for adjusting the position of a leg massage body (2300) with respect to a frame unit, specifically, a seat frame (1120).

[0295] A position adjustment unit (2700) according to one embodiment of the present invention provides a massage device (100) that can apply various movements related to leg massage to a user (10) by adjusting at least one of the height and angle of the leg massage body (2300).

[0296] Specifically, the position adjustment unit (2700) may include a length adjustment unit (not shown in the drawing) that can transmit power to the leg massage body (2300) to linearly move the leg massage body (2300) forward and / or backward with respect to the leg connection frame (1121).

[0297] In addition, the position adjustment unit (2700) may include a height adjustment unit (not shown in the drawing) that can linearly move the leg massage body (2300) that accommodates the leg of the user (10) in a preset direction, specifically, in a direction that moves the knee of the user (10) closer to the upper body of the user (10) or away from the upper body.

[0298] Hereinafter, with regard to the specific configuration of the position adjustment unit (2700) according to one embodiment of the present invention, the angle adjustment unit (2710) that rotates the leg massage body (2300) relative to the rotation frame unit (2100) will be described in detail.

[0299] Referring to FIGS. 4 to 7 and 15, an angle adjustment unit (2710) according to one embodiment of the present invention transmits power to a leg massage body (2300) to rotate it relative to a rotation frame unit (2100), and may include a support unit (2711) and an angle adjustment drive unit (2715).

[0300] Referring to FIG. 5, due to the operation of the angle adjustment unit according to one embodiment of the present invention, the leg massage body (2300) can rotate clockwise and / or counterclockwise with a preset rotation axis (AX4) as the rotation center axis.

[0301] That is, the angle adjustment unit (2710) transmits power to the contact frame (2311) formed in the leg massage body (2300), specifically the leg base part (2310), so that the leg base part (2310) can be rotated clockwise and / or counterclockwise with respect to the rotation frame part (2100), specifically the rotation frame body (2110), about a rotation center axis (AX4) that is set in advance.

[0302] In other words, since the angle adjustment unit (2710) transmits power to the leg massage body (2300), the leg massage body (2300) performs a hinge movement with respect to the rotation frame body (2110), and the leg angle can be adjusted by folding or unfolding the leg based on the knee area of ​​the user (10).

[0303] According to one embodiment of the present invention, a pair of angle adjustment units (2710) may be provided to correspond to a pair of leg massage bodies (2300).

[0304] Referring to FIGS. 5 to 7, a support member (2711) according to one embodiment of the present invention can be in contact with a leg massage body (2300) and can be rotatably connected to a leg connection frame (1121). The support member (2711) can include a support member (2712) and a contact member (2713).

[0305] The support body (2712) is rotatably connected to the leg connection frame (1121) and can be connected to the angle adjustment drive unit (2715).

[0306] Referring to FIG. 5, the support body (2712) can rotate with respect to the leg connection frame (1121) by receiving power from the angle adjustment drive unit (2715), and when the support body (2712) rotates toward the front side with respect to the leg connection frame (1121), the leg massage body (2300) can rotate with respect to the rotation frame body (2110) toward the front side.

[0307] Referring to FIGS. 5 to 7, the contact portion (2713) is rotatably coupled to the support body (2712) and can contact the contact frame (2311) formed on the leg massage body (2300), specifically, the leg base portion (2310).

[0308] The contact portion (2713) is rotatably connected to the support body (2712) in a roller manner and is capable of cloud contact with the contact frame (2311).

[0309] Accordingly, the support body (2712) that receives power from the angle adjustment driving unit (2715) can push the leg massage body (2300), and the leg massage body (2300) can adjust its angle by performing a hinge movement based on the rotation center axis (AX4) with respect to the rotation frame unit (2100), specifically, the rotation frame body (2110).

[0310] Due to the contact portion (2713), friction caused by contact between the angle adjustment portion (2710), specifically the support portion (2711), and the leg massage body (2300) can be reduced, and power can be transmitted to the leg massage body (2300) to rotate the leg massage body (2300) by a preset angle with respect to the rotation frame body (2110).

[0311] Referring to FIG. 7, the outer surface (2713r) of the contact portion (2713) facing the leg massage body (2300) according to one embodiment of the present invention may be formed in a convex shape with a predetermined radius of curvature toward the outside.

[0312] Specifically, the contact portion (2713) that can come into contact with the leg massage body (2300A) that accommodates the left leg of the user (10) may be formed in a convex shape with an outer surface (2713r) facing left based on the front of the user (10) seated on the massage device (100) having a predetermined radius of curvature.

[0313] Meanwhile, the contact portion (2713) that can come into contact with the leg massage body (2300B) that accommodates the right leg of the user (10) may be formed in a convex shape with an outer surface (2713r) facing to the right based on the front of the user (10) seated on the massage device (100) having a predetermined radius of curvature.

[0314] Since a pair of contact portions (2713) are formed in a convex shape with a predetermined radius of curvature toward the outside based on the front of the massage device (100), when the rotation frame portion (2100) and the leg massage body (2300) hinge-coupled to the rotation frame portion (2100) perform an abduction movement in which the rotation frame portion (2100) rotates outward by a preset angle based on the rotation center axis (AX1) with respect to the leg connection frame (1121) and / or an internal rotation movement in which the rotation frame portion (2300) rotates inward by a preset angle based on the rotation center axis (AX1), the contact portions (2713) maintain a stable state of contact with the contact frame (2311) and the angle of the leg massage body (2300) can be adjusted.

[0315] The angle adjustment driving unit (2715) can be length-adjusted and transmits power to the support unit (2711), and can be formed as an actuator. The angle adjustment driving unit (2715) according to one embodiment of the present invention is formed in an electric cylinder manner, but is not limited thereto, and various modifications such as a motor, linear motor, electronic motor, DC motor, AC motor, linear actuator, etc. capable of providing driving force within the technical concept of length adjustment are possible.

[0316] A control unit according to one embodiment of the present invention can control power by transmitting an electrical signal to an angle adjustment driving unit (2715).

[0317] According to an embodiment of the present invention, the leg massage body (2300A, 2300B) into which the user's (10) leg is inserted is rotated clockwise and / or counterclockwise around the rotation center axis (AX4) positioned close to the user's (10) knee, and the angle can be adjusted, thereby providing an effect of providing a massage.

[0318] According to one embodiment of the present invention, a massage device (100) can provide a leg adduction and / or abduction function to a user (10) by using power generated from a leg driving unit (2500) to rotate a rotation frame unit (2100) relative to a leg connection frame (1121).

[0319] Additionally, the power generated from the bridge drive unit (2500) is transmitted to a pair of rotating frame units (2100), allowing the pair of rotating frame units (2100) to rotate in opposite directions.

[0320] In addition, since the connecting member (2150) is movable inside the slit portion (2551) formed in the moving portion (2550), there is an effect in which the linear movement of the moving portion (2550) can be converted into the rotational movement of the rotating frame body (2110).

[0321] In addition, since the outer surface of the angle adjustment unit (2710) for adjusting the angle of the leg massage body (2300), specifically the contact portion (2713), is formed in a convex shape with a predetermined radius of curvature toward the outside based on the front of the user (10) seated on the massage device (100), there is an effect in which the contact portion (2713) can stably contact and support the leg massage body (2300) while the rotating frame body (2110) to which the leg massage body (2300) is coupled is rotated with respect to the leg connection frame (1121).
