[0106] Figure 3 FIG. 1 is a diagram showing a state in which a hand massage module is arranged on an arm massage part according to an embodiment of the present invention. Figure 3 The configuration status in is used as a baseline.

[0107] An arm receiving groove 3100 for receiving a user's arm is formed on the arm massage unit 3000, and a hand massage module 4000 capable of massaging the user's hand is disposed on the front portion of the arm receiving groove 3100.

[0108] An "L"-shaped arm airbag fixing frame 3110 is disposed on the arm receiving groove 3100. An upper airbag 3210 and a lower airbag 3220 for fixing or massaging the arm are coupled to the upper surface and the lower surface of the arm airbag fixing frame 3110. Additionally, the upper airbag 3210 can be configured to fix or massage the user's hand disposed on the hand massage module 4000.

[0109] The operation of the hand massage module 4000 is controlled by a control unit.

[0110] The control unit can simultaneously or selectively execute a hand massage mode based on the hand massage module 4000 and a massage mode for massaging the hand or the arm using airbags. Additionally, the control unit can execute the hand massage mode based on the hand massage module 4000 in a fixing mode that uses the operation of the airbags to fix the user's arm or hand.

[0111] According to an embodiment of the present invention, the hand massage module 4000 can be detachably (detachable and installable) coupled to the arm airbag fixing frame 3110 of the arm receiving groove 3100. To this end, coupling grooves such as a hook coupling groove 3112 and a guide coupling groove 3114 can be formed on the arm airbag fixing frame 3110.

[0112] Therefore, when the user wants to use the hand massage mode, it can be used by coupling the hand massage module 4000, and the hand massage module 4000 can be separated and detached from the arm airbag fixing frame 3110. When the hand massage module 4000 has been separated from the arm airbag fixing frame 3110, massage can be provided to the palm portion by additionally coupling a lower airbag to the corresponding portion.

[0113] The arm massage unit 3000 is disposed on two side portions of the body massage unit 1000. The hand massage module 4000 can be disposed on both of the two side arm massage units 3000, or can be disposed on one of the side arm massage units or the other side arm massage unit.

[0115] Additionally, the hand massage module 4000 can be configured to massage the acupoints of the hand or specific acupoints.

[0116] Additionally, the hand massage module 4000 according to an embodiment of the present invention can provide massage to the Hegu acupoint.

[0117] Hegu acupoint (Large Intestine 4, LI4) is a valley-shaped depression between the thumb and index finger. Hegu acupoint is widely known for its various effects and is called a point for curing all kinds of diseases. In particular, Hegu acupoint is widely known as a point that is very effective in improving indigestion and blood circulation.

[0118] In the prior art, acupressure (massage) of the Hegu point is performed by manpower, for example, by repeatedly pressing the Hegu point with the thumb of the other hand.

[0119] In order to increase the effect of acupressure on the Hegu point, it is more effective to perform acupressure with the hands relaxed. For example, when the fingers are pressed so that the thumb and the remaining four fingers are almost parallel, the muscles and ligaments of the hand will be in a tense state. When acupressure is performed on the Hegu point in this state, the tense muscles or ligaments will make it impossible to perform acupressure on the Hegu point effectively, and strong acupressure will cause pain.

[0120] When the force on the hand is removed and the hand is in a relaxed state, the remaining four fingers will be in a slightly bent state, and the thumb will be at a lower position than the index finger on the side. Therefore, the Hegu point will be located on the side of the hand.

[0121] The hand massage module according to the present invention is configured to perform hand massage (eg, Hegu acupoint massage) when the hands are in a relaxed state.

[0122] Figure 4 is a perspective view showing the back side of a hand massage module according to an embodiment of the present invention, Figure 5 is a side sectional view of a hand massage module according to an embodiment of the present invention, Figure 6 and Figure 7 1 is a perspective view showing a state in which some components are arranged in a state in which a cover of a hand massage module according to an embodiment of the present invention is removed.

[0124] The user's hand is placed on the main body 4100.

[0125] The main body 4100 includes a base 4110 , a receiving space 4120 formed inside the main body 4100 , and a cover 4130 .

[0126] The base 4110 is combined with the arm airbag fixing frame 3110. The main body 4100 includes hook engaging portions 4112 and 4114 detachably combined with the arm airbag fixing frame 3110. The hook engaging portions 4112 and 4114 are formed on the lower surface of the base 4110.

[0127] The hook engaging portions 4112 and 4114 are respectively disposed on the front side and the rear side of the lower surface of the base 4110. The first hook engaging portion 4112 on the front side is substantially formed in a "匚" shape on the front side of the lower surface of the base 4110 and bends and extends rearward. The first hook engaging portion 4112 has a hook protrusion that can be hooked on the hook engaging groove 3112. The second hook engaging portion 4114 on the rear side is substantially formed in a "匚" shape on the rear side of the lower surface of the base 4110 and bends and extends rearward. The second hook engaging portion 4114 is inserted into the guiding engaging groove 3114, and thus while being guided rearward, it is clamped on the peripheral portion of the guiding engaging groove 3114, and the hook protrusion of the first hook engaging portion 4114 is combined with the hook engaging groove 3112 in a manner of being hooked on the hook engaging groove 3112.

[0128] The lid 4130 has an accommodation space 4120 formed therein and is combined with the base 4110. The interior of the main body 4100 surrounded by the lid 4130 is formed as the accommodation space 4120. The accommodation space 4120 is provided with related components including a finger pressing driving portion.

[0129] The upper surface of the lid 4130 is formed as a finger support surface 4132, and the finger support surface 4132 at least partially supports the remaining fingers except the user's thumb. The finger support surface 4132 can be formed in an arc shape so that the user's hand can be placed on the finger support surface 4132 in a relaxed state.

[0130] The lid 4130 has a back surface 4134, a front surface 4135, a first side surface 4136, and a second side surface 4138. The first side surface 4136 is the side surface located in the direction towards the inside of the massage device, and the second side surface 4138 is the side surface facing the arm airbag fixing frame 3110.

[0131] A thumb guiding portion 4140 is formed on the back surface 4134 of the lid 4130 of the main body 4100 which is the rear side of the finger module 4000, and the thumb guiding portion 4140 positions the thumb of the hand at a lower position on the side of the index finger. The thumb guiding portion 4140 is adjacent to the first side surface 4136 of the lid 4130.

[0132] The thumb guiding portion 4140 includes a thumb insertion hole 4142, a first side wall 4144, a second side wall 4146, and a thenar groove 4148 for the thumb.

[0133] The thumb insertion hole 4142 is used to form a path for the thumb to be inserted into the accommodation space 4120 inside the main body 4100. The thumb insertion hole 4142 is located at the back side and is thus formed at a lower position than the finger support surface 4132.

[0134] The first side wall 4144 is formed on one side of the thumb insertion hole 4142, so as to face the Hegu acupoint when the thumb is inserted. A finger pressure rod hole 4145 is formed on the first side wall 4144, and the end 4211 of the finger pressure rod 4210 protrudes from the finger pressure rod hole 4145 (refer to Figure 4 The acupressure stick 4210 can directly press the Hegu acupoint while moving forward and backward through the acupressure stick hole 4145.

[0135] A second side wall 4146 and a thumb thenar groove 4148 are formed on a surface opposite to the first side wall 4144. The first side wall 4144 and the second side wall 4146 face each other on both sides of the thumb insertion hole 4142.

[0136] The second side wall 4146 is located inside the thumb thenar groove 4148 and is arranged opposite to the acupressure stick hole 4145. The strength adjustment block 4310 is movably arranged on the second side wall 4146. A guide member for movably supporting the strength adjustment block 4310 may be formed on the second side wall 4146.

[0137] The thenar groove 4148 can support at least a portion of the thenar eminence that is connected to the thumb and protrudes in the palm (ie, the thenar eminence).

[0138] Since the thumb guide 4140 including the thumb insertion hole 4142 is formed at a lower position than the upper surface formed by the finger support surface 4132, the thumb of the hand is located at a lower position than the index finger on the side of the index finger. Thus, the hand is guided to a relaxed state and the hand is supported on the main body 4100. At this time, the Hegu point will be located in the side direction of the hand.

[0139] The thenar thumb groove 4148 is configured to contact the thenar thumb of the user, thereby supporting the thenar thumb, thereby inducing relaxation of the hand and guiding the position of the hand.

[0140] The wrist tilting prevention portion 4400 is disposed adjacent to the back surface 4134 of the cover 4130, thereby preventing the wrist from tilting when the hand is placed on the main body 4100 while the thumb is inserted (see Figure 1 ).

[0141] The acupressure stick 4210 and the acupressure stick driving unit are arranged in the accommodation space 4120 and accommodated inside the cover 4130 .

[0142] Reference Figures 5 to 7 The finger pressure stick driving part is configured to provide a driving force for causing the finger pressure stick to move forward and backward, and the finger pressure stick driving part includes a motor 4230 and a motion converting part 4240.

[0143] The acupressure stick 4210 is arranged at a position corresponding to the Hegu acupoint of the hand in a manner that allows for an advance and retreat movement, thereby providing a massage for acupressure on the Hegu acupoint. The end 4211 of the acupressure stick 4210 can protrude through the acupressure stick hole 4145 formed on the first side wall 4144 of the thumb guide 4140. The end 4211 of the acupressure stick 4210 contacts the Hegu acupoint. The acupressure stick 4210 reciprocates with its end 4211 protruding and moving forward and backward, and repeatedly performs pressing and relaxing on the Hegu acupoint while providing acupressure.

[0144] The finger pressure stick 4210 is actuated by the rotation of the motor 4230 and moves linearly.

[0145] According to an embodiment of the present invention, the motor 4230 is supported on the base 4110 and is disposed adjacent to the second side surface 4138. The motor 4230 is fixed to the base 4110 by a motor fixture 4232. In the accommodation space 4120, the motor 4230 is disposed at a position opposite to the end 4211 of the acupressure stick 4210 across the thumb guide 4140 in the width direction (see FIG. Figure 5 ).

[0146] The finger pressure stick 4210 crosses the base 4110 in the width w direction of the accommodation space 4120 and extends toward the motor 4230. The finger pressure stick 4210 includes: an end 4211 protruding through the finger pressure stick hole 4145; a first extension portion 4212 perpendicularly intersecting the end 4211 and extending forward along the length direction L of the accommodation space 4120; and a second extension portion 4214 perpendicularly intersecting the first extension portion 4212 and extending across the accommodation space 4120 in the width w direction. The second extension portion 4214 is connected to the motor 4230 through the motion conversion portion 4240 to be driven by the motor 4230.

[0147] The motion conversion unit 4240 is configured to connect the acupressure stick 4210 and the motor 4230 , and is configured to convert the rotational motion of the motor 4230 into a linear reciprocating motion of the acupressure stick 4210 .

[0148] The motion conversion unit 4240 is coupled to the motor 4230 and is rotationally driven by the motor 4230. The motion conversion unit 4240 includes: a rotating disk 4245, on which a coupling pin 4242 is protruding; and a pin coupling unit 4246, which is connected to the second extension 4214 of the finger pressure stick 4210 and coupled to the coupling pin 4242. The rotating disk 4245 is arranged in a direction in which the coupling pin 4242 protrudes toward the back of the cover 4130. The pin coupling unit 4246 can be integrally formed on the finger pressure stick 4210, thereby forming the motion conversion unit 4240 while forming a part of the finger pressure stick 4210.

[0149] According to an embodiment of the present invention, the pin coupling portion 4246 extends in a manner of perpendicularly intersecting the second extending portion 4214 .

[0150] The pin coupling portion 4246 includes a slot hole 4247 extending long in the vertical direction. The slot hole 4247 has a length more than twice the distance between the center of the rotating disk 4245 and the coupling disk 4242. Therefore, the vertical motion component generated when the coupling pin 4242 rotates is absorbed by the coupling pin 4242 moving along the slot hole 4247, and the horizontal motion component generated when the coupling pin 4242 rotates is transmitted to the horizontal movement of the finger pressure stick 4210. Accordingly, the finger pressure stick 4210 can move forward and backward.

[0151] The vertical direction can refer to Figure 6 The coordinate system shown is based on the extension direction of the Z axis, and the horizontal direction may refer to a direction intersecting the Z axis (eg, the extension direction of the Y axis).

[0152] Therefore, the rotation of the motor 4230 can be converted into a linear movement of the acupressure stick 4210 in the forward and backward directions through the motion conversion unit 4240, and the acupressure stick 4210 can perform a massage on the Hegu point while performing a linear reciprocating motion.

[0153] According to an embodiment of the present invention, the base 4110 has a channel for the second extension portion 4214 to pass through, and has a guide portion 4215 for guiding the horizontal movement of the acupressure stick 4210 .

[0154] The first extension part 4212 extends downwardly inclining from the end 4211 toward the base 4110 and is connected to the second extension part 4214, and the pin coupling part 4246 extends upward from the second extension part 4214. The guide part 4215 guides the acupressure stick 4210 to move linearly while supporting it.

[0155] According to an embodiment of the present invention, the hand massage module 4000 further includes a finger pressure intensity adjustment unit 4300. The finger pressure intensity adjustment unit 4300 can adjust the finger pressure intensity of the finger pressure stick 4210 applied to the Hegu acupoint.

[0156] The finger pressure strength adjustment unit 4300 includes a strength adjustment block 4310 and a strength adjustment block moving unit.

[0157] The strength adjustment block 4310 is coupled to the second side wall 4146 of the thumb guide 4140 in a manner that it can move in a direction close to or away from the first side wall 4144. When the strength adjustment block 4310 approaches the first side wall 4144, the hand will be pushed on the opposite side of the Hegu acupoint of the hand, thereby moving the hand in the direction of the Hegu acupoint. Therefore, the position between the end 4211 of the acupressure stick 4210 and the Hegu acupoint is close, and the strength of the acupressure applied to the Hegu acupoint can be increased. When the strength adjustment block 4310 is away from the first side wall 4144, the acupressure strength can be reduced based on the same principle.

[0158] The strength adjustment block moving part can adjust the approach distance and the distance away (separation) relative to the first side wall 4144 by moving the strength adjustment block 4310 .

[0159] The strength adjustment block moving portion includes a strength adjustment pin 4320 and a strength adjustment pin fixing portion 4330 .

[0160] The strength adjustment pin 4320 is connected to the strength adjustment block 4310, and pulls and moves the strength adjustment block 4310. The strength adjustment block 4310 is configured to adjust the distance from the first side wall 4144 (ie, the approach distance and the distance away from the first side wall 4144).

[0161] The strength adjustment pin 4320 is connected to the strength adjustment block 4310 through a connection member 4312 , and extends along the length direction L inside the accommodation space 4120 .

[0162] The strength adjustment pin fixing portion 4330 is fixed at the moved position where the strength adjustment pin 4320 has been adjusted, so that the position of the strength adjustment block 4310 can be fixed.

[0163] According to an embodiment of the present invention, the strength adjustment pin 4320 may be formed to protrude from the front face 4135 of the main body 4100. A pin slot hole 4322 is formed on the front face of the cover 4130, and the pin slot hole 4322 allows the end 4321 of the strength adjustment pin 4320 to protrude to the outside and move. The strength adjustment pin 4320 extends to the outside of the main body 4100 (i.e., the cover 4130) and passes through the pin slot hole 4322 formed in the cover 4130, so that the outer end of the strength adjustment pin 4320 is exposed to the outside.

[0164] The strength adjustment pin 4320 may be provided with a strength adjustment pin spring 4325 sandwiched between the inner surface of the peripheral portion of the pin slot hole 4322 and the body of the strength adjustment pin 4320. The strength adjustment pin spring 4325 elastically supports the strength adjustment pin 4320 toward the strength adjustment pin fixing portion 4330.

[0165] The strength adjustment pin fixing part 4330 is arranged on the base 4110 in a manner corresponding to the end of the strength adjustment pin 4320, and is provided with a plurality of fixing grooves. The end of the strength adjustment pin 4320 is inserted into the fixing groove, thereby fixing the adjusted position. The strength adjustment pin fixing part 4330 can be formed integrally with the guide part 4215.

[0166] The user disengages the strength adjustment pin 4320 from the fixing groove of the strength adjustment pin fixing part 4330 by pulling the strength adjustment pin 4320 in front of the main body 4100. Afterwards, the user adjusts the protrusion of the strength adjustment block 4310 on the second side wall 4146 by moving the strength adjustment pin 4320, and then releases the strength adjustment pin 4320. The strength adjustment pin 4320 moves toward the strength adjustment pin fixing part 4330 through the strength adjustment pin spring 4325, and can be reinserted and fixed in the fixing groove corresponding to the set position. By selectively combining the strength adjustment pin 4320 with any one of the multiple fixing grooves of the strength adjustment pin fixing part 4330, the position of the strength adjustment block 4310 can be fixed.
