[0001] The present invention relates to a massage device capable of adjusting the length of a leg massage part, and more specifically, to a massage device capable of freely adjusting the elongation and / or telescopic distance of the leg length by separately driving a foot massage part and a calf massage part. Background Art

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

[0003] Due to economic and time reasons, the demand for massage devices or massagers that provide manual massage functions has increased. That is, as the demand for relaxing tense muscles and eliminating fatigue or stress through massage has increased, various massage devices with good time and cost benefits have been introduced.

[0004] Recently, people's concern for health is increasing, and massage devices have changed from simply providing a massage function to electronic devices providing a variety of additional functions and / or medical functions.

[0005] In addition, the massage device provides a massage function to the user's legs, but since the user's calf massage part and the foot massage part move together in a fixed state, it is difficult to reflect the various leg lengths of the user, thereby having a problem of reduced massage effect. Summary of the invention

[0006] Problem that the invention aims to solve

[0007] The problem to be solved by the present invention is to provide a massage device capable of adjusting the length of the leg massage part. Since the length driving part enables the calf massage part and the foot massage part to move independently, the device can improve the massage effect by freely adjusting the extension and / or telescopic distance of the leg massage part to match the user's leg length.

[0008] However, the problems to be solved by the present invention are not limited to the above-mentioned problems, but also include other problems that can be easily grasped by ordinary technicians in the technical field to which the present invention belongs based on this specification and drawings.

[0009] Means used to solve problems

[0010] In order to achieve the above-mentioned purpose, according to one embodiment of the present invention, there is provided a massage device, comprising a leg massage part into which a user's legs can be inserted, the leg massage part comprising: a leg base part; a calf massage part connected to the leg base part and capable of placing the user's calves; a foot massage part connected to the leg base part and capable of inserting the user's feet; and a length driving part, which transmits power to the calf massage part and the foot massage part to enable the calf massage part and the foot massage part to move independently along a preset direction.

[0011] Effects of the Invention

[0012] According to the present invention, the foot massage part and the calf massage part can be driven independently in the same or opposite directions on the leg base part, so that the leg length can be adjusted to match the body shape of the user.

[0013] In addition, since the foot massage part and the calf massage part can be driven separately, the stretching effect of the hip joint can be improved in the minimum extension state, and the stretching effect can be improved by increasing the leg length in the maximum extension state.

[0014] However, the effects of the present invention are not limited to the above-mentioned effects, but also include effects that can be easily grasped by a person skilled in the art according to the present specification and the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0138] Reference Figures 5 to 12 , shows any one of the plurality of leg massage parts 2000A and 2000B according to an embodiment of the present invention.

[0139] In addition to accommodating the right and left feet of the user 10, the multiple leg massage parts 2000A and 2000B have the same structure, operating principle and effect as the leg base part 2100, the calf massage part 2200, the foot massage part 2300, the length driving part 2400, the length sensor part 2500 and the hinge driving part 2700.

[0140] Reference Figures 5 to 8 , Fig.11 as well as Fig.12The leg base portion 2100 according to an embodiment of the present invention, which is connected to the frame portion 1100, can be hinged to the frame portion 1100 (specifically, the seat frame 1120) based on a preset hinge center axis AX1 (hereinafter referred to as the "rotation center axis").

[0141] Reference Figure 5 and Fig.12 The calf massage part 2200 and the foot massage part 2300 to be described later may be independently movably connected to the leg base part 2100 according to an embodiment of the present invention.

[0142] Reference Figures 5 to 8 as well as Fig.11 According to an embodiment of the present invention, the leg base portion 2100 may include a shaft portion 2110 and a leg base body 2150 .

[0143] Reference Figures 5 to 7 The shaft portion 2110 according to an embodiment of the present invention, which is capable of rotating about a predetermined rotation center axis AX1, is rotatably connected to the frame portion 1100.

[0144] Specifically, both sides of the shaft portion 2110 may be selectively rotatably connected to the frame portion 1100 (specifically, the seat frame 1120 ). The seat frame 1120 may be formed with hinge brackets (not shown) that can be connected to both sides of the shaft portion 2110 .

[0145] The hinge bracket according to an embodiment of the present invention may be integrally formed with the seat frame 1120 , but is not limited thereto, and may be variously deformed and implemented, such as being two components separately from the seat frame 1120 and being combined with the seat frame 1120 .

[0146] Reference Figure 2 as well as Figures 5 to 7 The shaft portion 2110 according to an embodiment of the present invention, which is rotatably connected to the frame portion 1100 , can perform a hinge motion (or rotation) in a clockwise direction and / or counterclockwise direction with respect to a preset rotation center axis AX1 .

[0147] Reference Figure 6 and Figure 7 According to an embodiment of the present invention, the rotation center axis AX1 of the shaft portion 2110 may be formed identically to the length direction center axis of the shaft portion 2110 .

[0148] According to an embodiment of the present invention, the shaft portion 2110 may be combined with the leg base body 2150 , and the leg base body 2150 receives power generated by a hinge driving unit 2700 to be described later to rotate the shaft portion 2110 with its longitudinal central axis as the rotation central axis AX1 .

[0149] Thus, the leg base body 2150 (to which the calf massage part 2200 and the foot massage part 2300 are movably connected) can rotate clockwise and / or counterclockwise relative to the frame part 1100 (specifically the seat frame 1120) with the rotation center axis AX1 as a reference.

[0150] That is, the leg massage part 2000 rotates forward or backward (with the user 10 sitting on the massage device 100 as a reference) with respect to the rotation center axis AX1 formed in the same longitudinal direction as the center axis of the shaft part 2110, thereby having the effect of adjusting the leg angle when receiving the leg massage function through the massage device 100.

[0151] The seat frame 1120 may be formed with a leg base portion 2100 (specifically, a groove portion (not marked in the figure) in which the shaft portion 2110 may be placed), and a shaft cover (not marked in the figure) may cover the shaft portion 2110 placed in the groove and be fastened to the groove.

[0152] Reference Figures 5 to 7 as well as Fig.12 According to an embodiment of the present invention, the shaft portion 2110 may include a shaft body 2111 , a shaft housing portion 2113 , and a fastening member 2117 .

[0153] The shaft body 2111 extending in the length direction is connected to the leg base body 2150 and can form a rotation center axis AX1 of the leg base body 2150 .

[0154] The shaft body 2111 may be made of metal and / or plastic material. When the shaft body 2111 is made of plastic material, it has the effect of reducing the weight of the leg massage part 2000 and the massage device 100.

[0155] The shaft body 2111 according to an embodiment of the present invention is combined with the leg base body 2150 and receives power from the hinge driving part 2700 so as to rotate together with the leg base body 2150 when the leg base body 2150 rotates.

[0156] However, the present invention is not limited thereto, and various modifications are possible within the technical concept that the longitudinal center axis of the shaft body 2111 forms the rotation center axis AX1 of the leg massage part 2000 , for example, the leg base body 2150 and the shaft body 2111 rotate relative to each other.

[0157] Since the shaft body 2111 is connected to the leg base body 2150, the leg base body 2150 and the calf massage part 2200 and the foot massage part 2300 movably connected to the leg base body 2150 can use the length direction center axis of the shaft body 2111 as the rotation center axis AX1 to perform hinge movement in the clockwise direction and / or counterclockwise direction relative to the frame part 1100.

[0158] That is, in a state where the user 10 sits on the massage device 100 , the leg massage part 2000 accommodating the legs of the user 10 may perform a hinge motion at a preset angle.

[0159] Reference Figure 6 and Figure 7 , the shaft body 2111 may be rotatably connected to the shaft housing portion 2113. Specifically, both sides of the shaft body 2111 may be connected to a pair of shaft housing portions 2113.

[0160] Reference Figure 7 , the shaft body 2111 can be inserted into the insertion groove portion 2114 formed in the shaft housing portion 2113.

[0161] The insertion groove portion 2114 may be formed at the shaft housing portion 2113 and have a preset depth, and the end portion of the shaft body 2111 may be inserted into the insertion groove portion 2114 formed at the shaft housing portion 2113 .

[0162] The end of the shaft body 2111 may be rotatably disposed inside an insertion groove portion 2114 formed in the shaft housing portion 2113 .

[0163] As an alternative embodiment, the outer circumference of the shaft body 2111 may be in surface contact with the inner circumference of the insertion groove 2114 formed in the shaft housing 2113. Thus, the shaft body 2111 may rotate inside the insertion groove 2114 while maintaining the rotation center axis AX1.

[0164] Reference Figure 7 According to an embodiment of the present invention, both ends of the shaft body 2111 are rotatably connected to a pair of shaft housing parts 2113 and can be inserted into insertion grooves 2114 respectively formed in the pair of shaft housing parts 2113.

[0165] Reference Figures 5 to 7 The shaft housing portion 2113 according to an embodiment of the present invention, which is disposed between the shaft body 2111 and the frame portion 1100 , can support the rotation of the shaft body 2111 .

[0166] The shaft housing portion 2113 may be provided in plurality, and the plurality of shaft housing portions 2113 may be respectively connected to both ends of the shaft body 2111. The shaft housing portion 2113 may be made of a plastic material.

[0167] This has the effect of reducing the weight of the leg massage part 2000 and the massage device 100.

[0168] Reference Figure 7The shaft housing portion 2113 may be formed with an insertion groove portion 2114 having a preset depth so that the shaft body 2111 can be inserted. The depth direction center axis of the insertion groove portion 2114 may be formed to be the same as the length direction center axis of the shaft body 2111.

[0169] One end of the shaft body 2111 may be inserted into the insertion groove 2114, and the shaft body 2111 may be rotatably disposed inside the insertion groove 2114. Also, since the shaft body 2111 is inserted into the insertion groove 2114, the shaft body 2111 may rotate while maintaining the rotation center axis AX1.

[0170] In addition, the leg base part 2100 coupled to the shaft body 2111 and the calf massage part 2200 and the foot massage part 2300 coupled to the leg base part 2100 can perform hinge motion.

[0171] Reference Figure 6 According to an embodiment of the present invention, a fastening hole portion 2115 is formed through the shaft housing portion 2113 .

[0172] The fastening hole portion 2115 formed in the shaft housing portion 2113 can be arranged to overlap with a hole portion (not shown) formed in the frame portion 1100 (specifically, the seat frame 1120), and the fastening member 2117 to be described later can penetrate the fastening hole portion 2115 and the hole portion formed in the seat frame 1120 and fasten the shaft housing portion 2113 and the seat frame 1120.

[0173] The coupling center axis AX2 of the fastening member 2117 may form a preset angle with the rotation center axis AX1 of the leg massaging part 2000. Specifically, the coupling center axis AX2 may be perpendicular to the rotation center axis AX1.

[0174] The insertion groove portion 2114 formed in the shaft housing portion 2113 according to an embodiment of the present invention may be configured to be spaced apart from the fastening hole portion 2115 by a predetermined distance.

[0175] Specifically, the shaft body 2111 can be inserted into the insertion groove 2114 formed in the shaft housing portion 2113 to the depth of the insertion groove 2114, and since the end of the insertion groove 2114 is separated from the fastening hole portion 2115, interference between the shaft body 2111 and the fastening member 2117 passing through the fastening hole portion 2115 can be prevented.

[0176] Furthermore, one side of the shaft housing portion 2113 is fixed to the frame portion 1100 (specifically, the seat frame 1120) by a fastening member 2117, and an insertion groove portion 2114 is formed on the other side opposite to the above-mentioned one side, and the shaft body 2111 can be rotatably inserted into the insertion groove portion 2114.

[0177] Furthermore, the insertion groove portion 2114 formed in the shaft housing portion 2113 is formed to surround the outer peripheral surface of the shaft body 2111, and since one side thereof is fixed to the frame portion 1100 (specifically, the seat frame 1120), there is no need for an additional covering member for covering the shaft body 2111, which has the effect of simplifying the hinge structure of the leg massage portion 2000.

[0178] As an optional embodiment, the shaft housing portion 2113 is configured on a hinge bracket formed on the seat frame 1120, and since the shaft cover (not shown) rotatably connected to the hinge bracket covers the shaft housing portion 2113, it has the effect of stably maintaining the longitudinal center axis of the shaft housing portion 2113 and the shaft body 2111.

[0179] Reference Figure 6 The fastening member 2117 according to an embodiment of the present invention, which penetrates and fastens the shaft housing portion 2113 and the frame portion 1100 (specifically the seat frame 1120), can pass through the fastening hole portion 2115 formed in the shaft housing portion 2113 and the hole portion formed in the seat frame 1120 and fasten the shaft housing portion 2113 and the seat frame 1120.

[0180] According to an embodiment of the present invention, the fastening member 2117 is a bolt, but is not limited thereto, and various modifications can be implemented within the technical concept of fixing one side of the shaft housing portion 2113 to the frame portion 1100 (specifically, the seat frame 1120).

[0181] The fastening member 2117 according to an embodiment of the present invention may be disposed apart from the shaft body 2111 inserted into the insertion groove 2114 formed in the shaft housing portion 2113 .

[0182] That is, since the fastening hole portion 2115 formed in the shaft housing portion 2113 is separated from the insertion groove portion 2114, the fastening member 2117 passing through the fastening hole portion 2115 is also separated from the insertion groove portion 2114 and can be separated from the shaft body 2111 that can be inserted into the insertion groove portion 2114.

[0183] As a result, the following effect is achieved: when one side of the shaft housing portion 2113 is fixed to the frame portion 1100 (specifically the seat frame 1120), the shaft body 2111 inserted into the insertion groove portion 2114 formed on the other side opposite to the above-mentioned one side can rotate freely while being separated from the fastening member 2117.

[0184] Reference Figures 5 to 8 , Fig.11 as well as Fig.12According to an embodiment of the present invention, the leg base body 2150 is connected to the shaft portion 2110 and can rotate in conjunction with the rotation of the shaft portion 2110 to rotate together.

[0185] The leg base body 2150 coupled to the shaft portion 2110 (specifically, the shaft body 2111 ) can rotate together with the shaft body 2111 .

[0186] Reference Figure 4 The leg base body 2150 can contact the hinge driving unit 2700 and can receive the power generated by the hinge driving unit 2700 to perform hinge motion (or rotation) using the length direction center axis of the shaft body 2111 as the rotation center axis AX1.

[0187] Reference Figure 4 The leg base body 2150 can rotate relative to the frame portion 1100 (specifically, the seat frame 1120) by using the longitudinal center axis of the shaft body 2111 as the rotation center axis AX1.

[0188] That is, since the shaft housing portion 2113 inserted and connected with the shaft body 2111 is fixed to the seat frame 1120, the longitudinal center axis of the shaft body 2111 can be fixed, and by using the longitudinal center axis of the shaft body 2111 as the rotation center axis AX1, the leg base portion 2100 can perform a hinge motion at a preset angle relative to the frame portion 1100.
