  However, in the air massage device disclosed in Japanese Patent No. 3012127 and the air massage machine disclosed in Japanese Patent No. 3012780, the lower limb massager for lower limb massage and the leg placement portion are held. Since the groove and the concave portion of the treatment recess are formed, and the concave portion is configured such that both the upper and front and rear ends are open, even in the lower limb of the user (user) Although it is a structure suitable for supporting and treating a certain lower leg, that is, a part from the knee to the ankle, it is not a structure suitable for treating the rear part of the heel.

  Moreover, in the chair type massage machine disclosed in Japanese Patent Laid-Open No. 2002-238963, when the legrest is vertically downward, the lower limb of the user (seat person) is bent at the knee. When the legrest is in a substantially horizontal state, the lower limb of the user is in a state of extending substantially straight. Here, the knee, which is the rotation center of the lower leg of the user, and the rotation center of the legrest are in different positions, so that when the legrest is in a substantially horizontal state than when it is vertically downward, The region above the lower limbs of the user (that is, the trunk side of the user) is held by the leg rest. Therefore, in the chair type massage machine disclosed in the publication, when the legrest is vertically downward, the user can easily place the legrest on the bottom surface of the groove of the footrest. When the footrest is in a substantially horizontal state, the footrest is rotated relative to the legrest so as to maintain the substantially horizontal state, so that the user can naturally extend the lower limb substantially straight. However, with this configuration, when the legrest is in a substantially horizontal state, the sole of the user cannot be supported.

  On the other hand, when the legrest is vertically downward, the foot of the user is in contact with the bottom of the footrest groove, so that the back of the heel, that is, the back side of the ankle does not contact the bottom of the groove, The rear cannot be treated. Therefore, when treating the rear part of the user's eyelid, it is necessary to rotate the legrest until it is in a substantially horizontal state, which is inconvenient.

  In addition, there are a number of acupuncture points on the back of the heel, for example, ginseng, toes, female knees, and bells. By stimulating this area, blood circulation promotion, fatigue recovery, and relaxation can be achieved. However, in the conventional chair-type massage device as described above, the rear part of the heel can be treated while supporting the sole. Nothing existed.

  The present invention has been made in view of such circumstances, and is suitable for treating the rear part of the heel. When the user is seated, whether the lower limb of the user is bent or not is determined. It is an object of the present invention to provide a chair-type massage device that can support the sole of the user.

  In order to solve the above problems, a chair-type massage apparatus according to the present invention is a chair-type massage apparatus including a seat portion on which a user is seated and a footrest disposed in front of the seat portion, wherein the footrest is A foot support surface that supports the sole of the user, a heel support surface that is erected on the rear side of the foot support surface and supports the rear portion of the heel of the user, and a heel support surface provided on the heel support surface. And a hemorrhoid treatment part that applies a pressing stimulus to the rear part of the user's hemorrhoid.

  By setting it as such a structure, since the back part of a heel can be treated in the state which supported the sole, the heel position at the time of treatment can be stabilized, and appropriate treatment can be performed. Moreover, it can be expected that various massage effects such as blood circulation promotion, fatigue recovery, relaxation, and function adjustment of various internal organs can be obtained by appropriately treating the rear part of the eyelid. Here, the “back part of the heel” includes the rear part of the ankle and the peripheral part of the Achilles tendon.

  Moreover, the said acupuncture treatment part may be comprised so that a pressing stimulus may be given to the rear part of the said wrinkles on both sides of the rear part of a user's reeds. With this configuration, the user sits on the seat, places the sole on the sole support surface, and receives treatment of the back of the heel in a natural posture with the heel supported on the heel support surface. be able to.

  The heel support surface is configured to support the rear of the heel of both legs of the user, and the heel of both legs of the user is interposed between the heel support positions for supporting the left and right heels. You may have the protrusion surface protrudingly provided so that it might guide to the said heel support position. By adopting such a configuration, the user's heel seated on the seat is naturally guided to the heel support position, so that troublesome alignment or the like is not required when receiving heel treatment.

  In addition, the heel support surface has concave surfaces that are arranged side by side on the left and right sides of the projecting surface and open forward to support the rear portions of the left and right heels of the user, respectively. You may be comprised so that the distance between right and left opposing surfaces may become large as it goes. By adopting such a configuration, the user's heel seated on the seat is more naturally guided to the heel support position, and convenience is improved.

  In addition, the bag treatment section may be configured such that air bags that expand and contract by being supplied and exhausted are respectively disposed on the left and right sides of the bag support position for supporting the user's bag. By adopting such a configuration, the rear part of the heel is relatively sensitive to pain, and by compressing with an air bag, an effective massage can be performed with almost no pain in the user. Become.

  The air bag is configured to expand from a substantially flat state to a substantially fan shape when supplied with air, and when the at least one pair of the air bags are inflated with respect to one heel support position, The pressing surfaces for pressing the ridges may be attached to the heel support surface so as to be close to each other. By setting it as such a structure, it can press with a simple structure so that the rear part of a user's heel may be pinched | interposed by the pressing surface of each air bag.

  Moreover, the said footrest may be comprised so that rotation to the front and back is possible centering | focusing on the rotating shaft provided in the front part of the said seat part, or its vicinity. By adopting such a configuration, it is possible to treat the rear part of the heel while supporting the sole, regardless of whether the lower limb of the seated user is bent or stretched.

  In the case of the chair-type massage device according to the present invention, the configuration is suitable for treating the rear part of the heel. When the user is seated, whether the lower limb of the user is bent or not is asked. First, there is an effect that the sole of the user can be supported.

By doing so, vibration stimulation can be given to the anal part of the user.

  Further, a backrest 3 is provided at the rear of the seat 2. The backrest 3 is large enough to prevent a part of the adult's body from protruding outside when an adult with a general physique sits on the chair-type massage device 1 to support the upper body of the user. It is assumed to be a rectangular shape in front view. The lower end portion of the backrest portion 3 is pivotally supported by a lateral pivot on the rear portion of the seat portion 2, and the reclining portion 3 can be reclining back and forth by rotating the backrest portion 3 around the pivot. Yes. In addition, armrests 5 fixedly supported on the base of the seat 2 are provided on both sides of the backrest 3. The armrest 5 extends forward from both sides of the backrest 3 and can be used as an elbow rest when the user sits on the chair type massage device 1.

  A massage mechanism 6 as shown in FIG. 2 is provided inside the backrest 3. FIG. 2 is an exploded perspective view showing the configuration of the massage mechanism 6 included in the chair type massage apparatus 1 according to the embodiment of the present invention. The massage mechanism 6 has four roller-shaped treatment elements 10 that apply mechanical stimulation to the body of the user. Further, motors 11 and 12 of a DC servo motor that drives the treatment element 10 to be displaced are provided. The treatment element 10 is attached to each of the tips of two V-shaped arms 13. Each arm 13 is attached to two connecting rods 14 each having a substantially V shape so as to be rotatable within a predetermined range. Each connecting rod 14 is provided with a fitting hole 15, and inclined portions 17 provided at both ends of the rotating shaft 16 are loosely fitted into the fitting hole 15. The inclined portion 17 is provided in a state inclined at a predetermined angle with respect to the rotating shaft 16. A helical gear 18a is coaxially provided at an intermediate portion of the rotating shaft 16, and the helical gear 18a meshes with the worm 18b. As described above, the helical gear 18a and the worm 18b constitute the worm gear mechanism 18.

  A pulley 19a is coaxially provided at one end of the worm 18b, and the pulley 19a and a pulley 19c provided on the output shaft of the motor 11 are connected by a belt 19b. Therefore, the rotational motion of the motor 11 is transmitted to the worm 18b via the belt 19b, and the rotating shaft 16 rotates by the rotation of the worm 18b. Then, as the rotary shaft 16 rotates, the inclined portion 17 is displaced so as to draw a conical locus, whereby the connecting rod 14 operates regularly, so that the left and right treatment elements 10 approach and separate from each other. And move so as to draw a substantially ellipse in the vertical direction. This is the massage operation of the treatment element 10. It should be noted that the massage operation of the treatment element 10 includes an operation of moving to the front (the user side) when the left and right treatment elements 10 approach each other and moving backward when the left and right treatment elements 10 are separated. As described above, in the massage operation, the treatment element 10 moves three-dimensionally.

As shown in FIGS. 4 to 7, the calf resting member 4 a includes a calf support surface 34 that supports calves of both legs of the user, and two side walls 33 that extend forward from both side ends of the calf support surface 34. Thus, one concave groove is formed with the front and upper and lower ends open respectively.

  Further, as shown in FIG. 7, the calf support surface 34, which is the bottom surface of the concave groove portion of the calf resting member 4 a, has rounded depressions 34 a arranged side by side so as to easily place the calf left and right of the user. . The size of these recesses 34a is very small compared to the size of the concave groove portion of the calf resting member 4a, so that the calf support surface 34 is substantially flat. Therefore, when the user puts the calves of both legs on the calf resting member 4a, the calf is restrained by the slightly projecting forward portion formed between both the depressions 34a of the calf support surface 34. In other words, the user can move the lower leg freely in the concave groove portion of the calf resting member 4a, and can take a free posture. Note that the term “substantially flat” as used herein refers to a portion that does not substantially have a protruding portion that significantly impairs the mobility of the lower leg of the user.

  An air bag 35 is disposed in each of the recesses 34 a of the calf support surface 34, and an air bag 36 is disposed on the opposing surface of both side walls 33. Each of the air bags 35 and 36 can be expanded in a bellows shape at one end and is not expanded at the other end, and can expand into a fan shape when supplied from a substantially flat state. It has become. The two air bags 35 are fixed to the recesses 34a of the calf support surface 34 with their one deployable ends close to each other, that is, with the one ends facing each other inward. The air bag 36 is fixed to the inner side surface of the side wall 33 with one expandable end facing forward. The air bags 35 and 36 are communicated with the air supply / exhaust device 9 described above, and the air bags 35 and 36 can be expanded or contracted by driving the air supply / exhaust device 9 (FIG. 14). reference).

  The right air bladders 35 and 36 are used for the treatment of the right leg calf for the user, and the left air bags 35 and 36 are used for the treatment of the calf for the left leg of the user. The front surface of the air bag 35 and the surfaces of the two air bags 36 facing each other are pressing surfaces 35a and 36a that press the rear and outer portions of the calf of the user. When the right air bladders 35 and 36 are supplied with air, the air bags 35 and 36 expand in a fan shape so that the pressing surfaces 35a and 36a are close to each other. Further, the left air bladders 35 and 36 also expand in a fan shape so that the pressing surfaces 35a and 36a come close to each other when supplied. Thereby, a pressing stimulus can be given to the calf with the calf's calf interposed therebetween.

  Thus, the calves treatment part based on this invention is comprised by the air bags 35 and 36. FIG.

  On the other hand, as shown in FIGS. 4, 5, 6, 8, and 9, the footrest member 4 b includes a sole support surface 37 that supports the sole of the user, and the sole support surface 37.

Therefore, the space in front of the projecting surface 38d is opened, so that the user can freely move his / her toes and can take a more comfortable posture.

  When the user performs a predetermined operation input to the operation unit 66 (see FIG. 14), an operation signal is transmitted from the operation unit 66 to the control circuit 62, and a control signal corresponding to the operation signal is transmitted. Is transmitted to the drive circuit 65. The drive circuit 65 drives the motor 56 in response to the control signal, and thereby the footrest 4 is expanded and contracted. As a result, the separation distance between the sole support surface 37 and the heel support surface 38 from the seating surface 2b is changed, and the user adjusts the sole support surface 37 according to the length of his / her own leg. Adjust the distance. At this time, an operation input different from the predetermined operation input is performed on the operation unit 66 to rotate the footrest 4 back and forth, and the angle between the sole support surface 37 and the heel support surface 38 and the seat surface 2b. Can also be changed.

  Further, when the footrest 4 is extended, the wheel 61 may come into contact with the floor. When the footrest 4 is rotated forward from the vertically extended state (that is, the state shown in FIG. 1), the angle is adjusted so that the footrest 4 does not return to the vertically extended state by its own weight. Configured to maintain. This configuration will be described in more detail. When the inclination angle of the footrest 4 is changed by operating the above-described rotation device, the rotation of the footrest to the rear of the changed inclination angle is restricted. However, the forward rotation is free from the inclination angle. Therefore, it is possible to manually rotate the footrest ahead of the inclination angle. With such a configuration, when the wheel 61 comes into contact with the floor while the footrest 4 is being extended, the wheel 61 rolls on the floor according to the extension of the footrest 4, and the footrest is rotated forward accordingly. It will be. Thereby, an extension of a footrest can be performed smoothly, without damaging a floor surface.

  The user performs the expansion and contraction adjustment and the angle adjustment of the footrest 4 as described above, and the user places the right and left soles on the right sole support position 37b and the left sole support position 37c, respectively, in a desired posture. State. Thereafter, the user performs an operation input for instructing the operation unit 66 to start the massage of the leg, whereby the massage of the leg is started.

  Moreover, in the chair type massage apparatus 1 according to the embodiment of the present invention, the sole support surface 37 and the heel support surface 38 are maintained at substantially the same angle with respect to the seat surface 2b, that is, the footrest 4 is moved back and forth. The footrest 4 can be expanded and contracted while maintaining a constant inclination angle without rotating, and the separation distance between the sole support surface 37 and the heel support surface 38 and the seat surface 2b can be changed. Therefore, when the user is seated on the chair-type massage apparatus 1, the planter's foot is always supported by the sole support surface 37 regardless of whether the lower limb of the user is bent or not. Is possible. In addition, this makes it possible to adjust the position of the sole support surface 37 so that the user can take a natural posture in accordance with the physique of the user. Note that maintaining substantially the same angle here means that the sole of the seated user can be supported by the sole support surface 37 and the rear portion of the user's heel can be supported by the heel support surface 38. A change in the relative angle between the sole support surface 37 and the heel support surface 38 and the seat surface 2b is allowed.

  In addition, since the sole and the heel of the user can be supported by the sole support surface 37 and the heel support surface 38, respectively, the sole and heel of the user can be stabilized at the same time.

  Further, the footrest 4 is rotated to a desired inclination angle and then expanded and contracted to maintain the relative angle of the sole support surface 37 and the heel support surface 38 with respect to the seating surface 2b, while maintaining substantially the same angle. Since the separation distance between the heel support surface 38 and the seating surface 2b can be changed, for example, in both the state where the lower limb of the user is bent with the knee and the state where the lower limb is extended substantially straight, The sole of the user and the rear part of the heel can be reliably supported.
