The topical massage device 100 is installed to the seating plate of the massage chair 1, and if the power is supplied to the vibrator 120, the vibration plate 160 coupled to the shaft of the vibrator and the massage pad 110 engaged to the upper portion of the vibration plate are softly vibrated at high speed to provide the effective vibration massage to the perineal region and the anal region, thereby preventing the disease of the prostate, improving circulation of blood, and relieving the stress.
The lower portion of the backrest unit 10 of the massage chair includes a lumbar stretching unit 70 having a lumbar supporter 72 connected to an actuator 79 using a cylinder or an electric motor and moved up and down by the actuator, and a cushion 73 attached to the lumbar supporter 72.
Referring to
If the cushion 73 has an air tube which is expanded or contracted by pneumatic pressure, the cushion 72 is connected to an air hose 73a for supplying the air, so that the size of the air tube is properly varied by the pneumatic pressure to give the optimum stretching effect to the user.
The lumbar stretching unit 70 can further improve the stretching effect of the whole body when it is used in cooperation with the upper body stretching unit 50 and the footrest unit providing the lower body stretching function.
Also, the actuator 79 has a rack 81 connected to the driving motor M provided in the massage chair to receive the rotating force, and a pinion 82 connected to a rear end of the lumbar supporter 72 and meshed with the rack 81.
One side of the actuator 79 is fixed to a roller carrier 440, and the roller carrier 440 reciprocates in a vertical direction near the lumbar vertebrae of the user in a stretching mode of the massage chair. When the roller 74 is pushed by operation of the actuator 79, the roller 74 reciprocates in the vertical direction near the waist region while being self-spinning, so that the waist of the user is spread by the rotary roller 74, thereby further improving the stretching effect.
The invention is characterized by further including an air conditioner 460 for supplying air to the operation space 10a in which the massage rollers 40 are operated between the support frames 11, thereby feeding the air of temperature which is wanted by the user.
Referring to
When the massage rollers 40 are operated to pressurize the back and waist of the user, the body is lifted by the massage rollers, so that a wide space is formed around the massage rollers which come into contact with the body. Preferably, the air is fed to the space to supply sufficient air and thus obtain the excellent air discharging effect.
To this end, the massage roller fixture 420 or the roller carrier 440 is connected to an air supply hose 450 made of flexible material to correspond to vertical movement of the massage rollers 40. A rear end of the air supply hose 450 is provided with the air conditioner 460 for supplying hot or cold air, thereby supplying the hot or cold air to the position for massaging the back of the user.
As illustrated in
The air conditioner 460 is provided with a heater for heating the air and a cooler for cooling the air. In the case where the massage chair is disposed in a room, the air conditioner may be provided with a fan to suck fresh indoor air through an inlet port and supply it to the air supply hose.
