Description

Massage device with adjustable length of leg massage part

[0001] The present invention relates to a massage device capable of adjusting the length of a leg massage part, and more particularly, to a massage device capable of freely adjusting the length of the leg 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 because the user's calf massage part and foot massage part were fixed and moved together, making it difficult to reflect the user's various leg lengths.

[0006] The problem to be solved by the present invention is to provide a massage device capable of adjusting the length of a leg massage part, which can freely adjust the elongation and / or expansion distance of the leg massage part according to the length of the user's legs by independently moving the calf massage part and the foot massage part, thereby improving the massage effect.

[0007] 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.

[0008] In order to achieve the above-described object, according to one embodiment of the present invention, a massage device including a leg massage unit into which a user's leg can be inserted, the leg massage unit including: a leg base unit; a calf massage unit on which a user's calf can be rested and connected to the leg base unit; a foot massage unit into which a user's foot can be inserted and connected to the leg base unit; and a length driving unit that transmits power to the calf massage unit and the foot massage unit to independently move the calf massage unit and the foot massage unit along a preset direction.

[0009] According to the present invention, the foot massage unit and the calf massage unit can be independently driven in the same or opposite directions on the leg base unit, thereby providing the effect of adjusting the leg length to suit the user's body type.

[0010] In addition, since the foot massage part and the calf massage part can be operated separately, the hip joint stretching effect can be increased in the minimum extension state, and the stretching effect can be increased by increasing the leg length in the maximum extension state.

[0011] 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.

At least one of the first upper cover (2437a) and the first lower cover (2437b) may be coupled to a first connecting portion (2210), specifically, a first-1 body (2211a) provided in a first connecting body (2211).

[0310] The first upper cover (2437a) is coupled to the first lower cover (2437b) and can accommodate one side (upper side as shown in FIG. 10) of the first moving part (2433). The first moving part (2433) can be rotatably connected to the first upper cover (2437a).

[0317] Since the first upper cover (2437a) and the first lower cover (2437b) accommodate the first moving part (2433), the first moving part (2433) can stably rotate on the fixed shaft (2410) and be supported so as to move along a preset direction (up and down direction based on FIG. 9).

[0318] A groove (not specified in the drawing) for accommodating a first support member (2439), which will be described later, may be formed in the first upper cover (2437a) and the first lower cover (2437b). Since the first support member (2439) is positioned in the groove and can come into contact with the first moving member (2433), there is an effect of stably supporting the rotation of the first moving member (2433).

[0319] In addition, the friction between the first cover housing (2437) and the first moving part (2433) can be reduced due to the first support member (2439), and damage to the first moving part (2433) and the first cover housing (2437) due to such friction can be prevented.

[0354] Since the second upper cover (2457a) and the second lower cover (2457b) accommodate the second moving part (2453), the second moving part (2453) can stably rotate on the fixed shaft (2410) and be supported so as to move along a preset direction (up and down direction based on FIG. 11).

[0355] A groove (not specified in the drawing) for accommodating a second support member (2459), which will be described later, may be formed in the second upper cover (2457a) and the second lower cover (2457b). The second support member (2459) is positioned in the groove and can come into contact with the second moving member (2453), thereby providing an effect of stably supporting the rotation of the second moving member (2453).

[0393] Referring to FIG. 12, as power is generated from the length driving unit (2400), specifically, the first driving body unit (2430) and the second driving body unit (2450), the first moving unit (2433) and / or the second moving unit (2453) can move on the fixed shaft (2410).

[0394] Referring to FIG. 12, as the first moving unit (2433) and the second moving unit (2453) move away from each other, the first moving unit (2433) can move to the first moving position (BL1`) and the second moving unit (2453) can move to the second moving position (BL2`).

[0395] Referring to FIG. 12, the first movement position (BL1`) and the second movement position (BL2`) can be spaced apart by a second distance (d2), and the state in which the calf massage part (2200) and the foot massage part (2300) are the farthest apart is illustrated.

[0396] According to one embodiment of the present invention, the length driving unit (2400) has a first driving body unit (2430) and a second driving body unit (2450) that are independently driven, so that the calf massage unit (2200) coupled with the first driving body unit (2430) and the foot massage unit (2300) coupled with the second driving body unit (2450) can move independently of each other.

[0397] That is, when the calf massage part (2200) moves in the first direction (from the lower side to the upper side in FIG. 12) by driving the length driving part (2400), specifically the first driving body part (2430), the foot massage part (2300) moves in the same direction as the first direction by driving the length driving part (2400), specifically the second driving body part (2450), thereby moving the user's knee toward the upper body, thereby providing a hip joint stretching function.

[0398] In addition, when the calf massage part (2200) moves in the first direction (from lower to upper in FIG. 12) by driving the length driving part (2400), specifically the first driving body part (2430), the foot massage part (2300) moves in the second direction (from upper to lower in FIG. 12) opposite to the first direction by driving the length driving part (2400), specifically the second driving body part (2450), thereby providing a stretching function by lengthening the user's legs or having the effect of adjusting the leg length to suit the body type of the user (10).

[0399] In addition, when the calf massage part (2200) moves in the second direction by driving the length driving part (2400), specifically the first driving body part (2430), the foot massage part (2300) moves in the same direction as the second direction by driving the length driving part (2400), specifically the second driving body part (2450), and can provide a stretching function by pressing the user's thigh toward the seat part (1000a).

[0400] In addition, when the calf massage part (2200) moves in the second direction (from the upper side to the lower side in FIG. 12) by the driving of the length driving part (2400), specifically the first driving body part (2430), the foot massage part (2300) moves in the first direction, which is the opposite direction to the second direction, by the driving of the length driving part (2400), specifically the second driving body part (2450), thereby having the effect of being able to adjust the leg length to suit the body shape of the user (10).

[0401] According to one embodiment of the present invention, a massage device (100) is formed with a calf massage unit (2200) and a foot massage unit (2300) that are formed integrally and do not move together, but can be driven separately on a leg base unit (2100), thereby providing a stretching function to a user (10) or having the effect of adjusting the leg length to suit the body shape of the user (10).

[0402] In addition, since the foot massage unit (2300) and the calf massage unit (2200) can be driven separately, the hip joint stretching effect can be increased in the minimum extension state, and the leg length can be increased in the maximum extension state to increase the stretching effect.

[0403] As an optional embodiment, the calf massage body (2250) may be provided in multiple pieces and may be separated in the up-down direction (based on FIG. 5), and the first driving body part (2430) may be provided in multiple pieces to correspond to the multiple calf massage bodies (2250).

[0404] This allows multiple calf massage units (2250) to be driven separately, and the massage modules provided in each of the multiple calf massage units (2250) to move along different positions on the user's calf to provide a massage function, or to adjust the length of the calf massage unit (2200) to suit the length of the user's calf.

[0405] As an optional embodiment, the foot massage body (2350) may be provided in multiple pieces and may be separated in the up-down direction (based on FIG. 5), and the second driving body part (2450) may be provided in multiple pieces to correspond to the multiple foot massage bodies (2350).

[0406] This allows multiple foot massage units (2350) to be driven separately, and the massage modules provided in each of the multiple foot massage units (2350) to move along different positions on the user's foot area to provide a massage function, or to adjust the length of the foot massage unit (2300) to suit the length of the user's foot area.

[0407] The multiple foot massage bodies (2350) can be placed in various variations, such as being separated up and down based on the area where the user's peach bones are located.
