Description

TECHNICAL FIELD

[0001] The present application relates to a chair-type massager provided with a leg rest member. BACKGROUND

[0002] Conventionally, various chair-type massagers provided with a leg rest member have been developed. For example, the chair-type massager disclosed in Japanese Patent Application Publication No. 2020-25628 is a structure in which a foot support portion and a leg support portion can be adjusted to an arbitrary position of a subject without causing the subject to feel bored. SUMMARY

[0003] Problems to be Solved by the Invention

[0004] The chair-type massager described above is configured to include a first frame that supports a leg support portion, a second frame that supports a foot support portion, and a third frame that supports the first frame and the second frame.

[0005] The chair-type massager described above is a structure in which both the first frame and the second frame are supported by the third frame, and therefore if the position adjustment range of the leg support portion and the position adjustment range of the foot support portion are both made large in order to be able to adequately cope with a subject having a large body size, there is a problem in that the third frame becomes large.

[0006] The large size of the third frame leads to, for example, an increase in the cost of the leg rest member, an increase in weight, and the like. In addition, if the weight of the leg rest member increases, the cost of a drive mechanism for rotating the leg rest member also increases.

[0007] The present application is made in view of the above-described circumstances, and aims to provide a chair-type massager that can adjust the positions of a portion that contacts the calf of a subject and a portion that contacts the sole of a subject, and that adopts a compact configuration and has large position adjustment ranges for these portions.

[0008] Means for Solving the Problems

[0009] The chair-type massager disclosed in the present specification is of the following structure (first structure) and includes a seat portion that supports the buttocks and thighs of a subject, a base frame that is located below the seat portion, and a leg rest member that houses the lower legs of the subject and is rotatably attached to the base frame. The leg rest member includes a fixed frame that is rotatably attached to the base frame, an intermediate frame that is slidably attached to the fixed frame, an ankle frame that is slidably attached to the intermediate frame, a first drive portion that causes the intermediate frame to slide relative to the fixed frame in a direction from the knees of the subject toward the ankles and a reverse direction thereof, and a second drive portion that causes the ankle frame to slide relative to the intermediate frame in a direction from the knees of the subject toward the ankles and a reverse direction thereof.

[0010] The chair-type massager of the first structure described above can be of the following structure (second structure), in which the leg rest member further includes a calf contact portion that is attached to the intermediate frame and comes into contact with the calves of the subject when the leg rest member houses the lower legs of the subject, and a sole contact portion that is attached to the ankle frame and comes into contact with the soles of the subject when the leg rest member houses the lower legs of the subject.

[0011] The chair-type massager of the second structure described above can be of the following structure (third structure), in which the slidable length of the intermediate frame relative to the fixed frame is longer than the slidable length of the ankle frame relative to the intermediate frame in a direction from the knees of the subject toward the ankles and a reverse direction thereof.

[0012] The chair-type massager of the second or third structure described above can be of the following structure (fourth structure), in which the leg rest member further includes a calf restraint portion that restrains the calves of the subject from moving relative to the calf contact portion in a direction from the knees of the subject toward the ankles, and a sole restraint portion that restrains the soles of the subject from moving relative to the sole contact portion in a direction away from the sole contact portion. In a state in which the calf restraint portion restrains the movement of the calves of the subject and the sole restraint portion restrains the movement of the soles of the subject, the second drive portion causes the ankle frame to slide in a direction away from the intermediate frame.

[0013] For the chair-type massager of the above-described second or third structure, it can be the following structure (fifth structure) that the pad leg member further includes a foot bottom restraining portion that restrains the foot bottom of the subject from moving in a direction away from the foot bottom contact portion with respect to the foot bottom contact portion, and the chair-type massager further has a thigh portion restraining portion that restrains the thigh portion of the subject from moving in a direction from the thigh root of the thigh portion of the subject toward the knee portion with respect to the seat portion, and in a state where the thigh portion restraining portion restrains the movement of the thigh portion of the subject and the foot bottom restraining portion restrains the movement of the foot bottom of the subject, the second drive portion causes the ankle frame to slide in a direction away from the intermediate frame.

[0014] For the chair-type massager of the above-described second or third structure, it can be the following structure (sixth structure) that the pad leg member further includes a foot bottom restraining portion that restrains the foot bottom of the subject from moving in a direction away from the foot bottom contact portion with respect to the foot bottom contact portion, and in a state where the position of the pad leg member with respect to the base frame is adjusted so that a direction from the thigh root of the thigh portion of the subject toward the knee portion and a direction from the knee portion of the subject toward the ankle cross each other and the foot bottom restraining portion restrains the movement of the foot bottom of the subject, the second drive portion causes the ankle frame to slide in a direction away from the intermediate frame.

[0015] Effects of the Invention

[0016] According to the chair-type massager disclosed in this specification, the positions of the portion that contacts the calf of the subject and the portion that contacts the foot bottom of the subject can be adjusted, and these positions can be adjusted by a compact structure.

[0034] Hereinafter, an example of the embodiment of the present application will be described in detail with reference to the drawings.

[0035] Figure 1 is a front perspective view of the chair-type massager 100 of the present embodiment. Note that, in Figure 1 , although a part of the first air bag Al and the third air bag described later is not blocked by other members, the illustration of the first air bag Al and the third air bag is omitted. In the following description, the front side (front side) when viewed from a subject seated on the chair-type massager 100 will be referred to as the "front side", and the rear side (back side) when viewed from a subject seated on the chair-type massager 100 will be referred to as the "rear side". In addition, the upper side (head side) when viewed from a subject seated on the chair-type massager 100 will be referred to as the "upper side", and the lower side (leg side) when viewed from a subject seated on the chair-type massager 100 will be referred to as the "lower side". In addition, the right side when viewed from a subject seated on the chair-type massager 100 will be referred to as the "right side", and the left side when viewed from a subject seated on the chair-type massager 100 will be referred to as the "left side".

[0036] The chair-type massager 100 is provided with a seat portion 200, a backrest portion 300, a base portion 400, an arm treatment portion 500, an operation portion 600, a cable 700, a stand 800, and an ottoman member 900.

[0037] The seat portion 200 supports the buttocks and the thighs of a subject. A base frame (not illustrated in Figure 1 is located below the seat portion 200.

[0038] The backrest 300 supports the shoulders, waist, and back of the patient. The backrest 300 is mounted at the rear end of the seat 200 in a manner that allows it to rotate about a reclining axis extending laterally. The backrest 300 has built-in guide rails 300B and 300C extending along the surface 300A that contacts the patient's shoulders and waist. A back massage unit (not shown) is guided by the guide rails 300B and 300C and moves up and down within the backrest 300. It should be noted that the guide rails 300B and 300C can also be extended to the rear of the seat 200, thereby allowing the back massage unit to move up and down within the seat 200 and the backrest 300. The back massage unit includes: a back massage element that moves up and down along the patient's back; a kneading drive mechanism that causes the back massage element to perform a kneading motion; and a tapping drive mechanism that causes the back massage element to perform a tapping motion.

[0039] The base portion 400 is erected on the left and right sides of the base portion 200 and below the base portion 200.

[0040] The arm treatment unit 500 is erected on the left and right sides of the base 200 and above the base 200. The arm treatment unit 500 has a built-in expandable and contractible bag, which supports the patient's arm while the treatment is performed.

[0041] The operation unit 600 is an input device for the user to select the treatment mode and adjust the intensity of the treatment. The operation unit 600 is connected via a cable 700 to a control unit (not shown) located below the seat 200. The control unit (not shown) controls various parts of the chair massager 100 based on signals output from the operation unit 600.

[0042] The support 800 is fixed to the arm treatment unit 500 located on the left side of the seat 200. The operating unit 600 can be installed and detached from the support 800.

[0043] The leg support component 900 accommodates the lower leg of the person receiving treatment. The leg support component 900 is rotatably mounted to the base frame. Figure 1 (Not shown in the figure). More specifically, the pad leg component 900 is capable of rotating about an axis AX extending in the left-right direction (see Figure 1). Figure 2 and Figure 3 It is mounted on the base frame by rotation. Figure 1 (Not shown in the diagram). The leg support component 900 is located on the base frame ( Figure 1 (Not shown in the image) in front.

[0044] Figure 2 This is a perspective view showing the frame, etc., of the leg support component 900. Figure 3 This is a front view showing the frame, etc., of the leg support component 900. It should be noted that... Figure 2In the middle, the upper end surface of the portion of the mounting leg part 900 of the base frame F0 is illustrated with a broken line.

[0045] The leg part 900 includes a fixed frame F1, an intermediate frame F2, and an ankle frame F3.

[0046] The fixed frame F1 is rotatably mounted to the base frame F0. In more detail, the fixed frame F1 is rotatably mounted to the base frame F0 about a rotation axis AX extending in the left-right direction.

[0047] The intermediate frame F2 is slidably mounted to the fixed frame F1. Figure 2 Figure 3 The state in which the intermediate frame F2 is closest to the fixed frame F1, in other words, the state in which the intermediate frame F2 is most retracted to the fixed frame F1 side is illustrated.

[0048] The ankle frame F3 is slidably mounted to the intermediate frame F2. Figure 2 Figure 3 The state in which the ankle frame F3 is closest to the intermediate frame F2, in other words, the state in which the ankle frame F3 is most retracted to the intermediate frame F2 side is illustrated.

[0049] Two rollers R1 that perform therapy on the lengthwise central portion of the sole of the subject are mounted on the ankle frame F3. The two rollers R1 are arranged in the left-right direction. The roller R1 arranged on the right side among the two rollers R1 performs therapy on the lengthwise central portion of the right sole of the subject. The roller R1 arranged on the left side among the two rollers R1 performs therapy on the lengthwise central portion of the left sole of the subject. Note that the lengthwise central portion of the sole is also referred to as the instep. The roller R1 has a protruding portion that protrudes to the radial outside of the roller R1.

[0050] A shaft S1 for eccentric mounting of the roller R1 is also mounted on the ankle frame F3. The shaft S1 extends in the left-right direction.

[0051] A rotation drive mechanism that rotates the shaft S1 is also mounted on the ankle frame F3. The rotation drive mechanism includes a motor M3, and transmits the rotational drive force of the motor M3 to the shaft S1.

[0052] The leg part 900 also includes a first drive portion D1 and a second drive portion D2.

[0053] The first drive portion D1 causes the intermediate frame F2 to slide with respect to the fixed frame F1 in the direction from the knee portion of the subject toward the ankle and the opposite direction. The structure of the first drive portion D1 is not particularly limited, and in the present embodiment is an electric linear motion mechanism including a motor M1.

[0054] ​​The second driving section D2 causes the ankle frame F3 to slide with respect to the intermediate frame F2 in a direction from the knee of the subject toward the ankle and a direction opposite thereto. The structure of the second driving section D2 is not particularly limited, and in the present embodiment is an electric linear motion mechanism including a motor M2. Note that the structure of the second driving section D2 can be the same as that of the first driving section Dl, or can be different from that of the first driving section Dl.

[0055] The legrest member 900 also includes a calf contact portion Cl (see Figure 1 ) and a foot bottom contact portion C2 (see Figure 1 ).

[0056] The calf contact portion Cl contacts the calf of the subject when the legrest member 900 accommodates the lower leg of the subject. In the present embodiment, the calf contact portion Cl is part of an outer cover of, for example, synthetic leather, natural leather, or the like, and is fixed to the intermediate frame F2. The calf contact portion Cl is attached to the intermediate frame F2. Therefore, by causing the intermediate frame F2 to slide with respect to the fixed frame Fl, the position of the calf contact portion Cl, which is the portion that contacts the calf of the subject, can be adjusted. Thus, the calf contact portion Cl can be adjusted to an appropriate position regardless of whether the subject is a large person or a small person.

[0057] The foot bottom contact portion C2 contacts the foot bottom of the subject when the legrest member 900 accommodates the lower leg of the subject. In the present embodiment, the foot bottom contact portion C2 is part of an outer cover of, for example, synthetic leather, natural leather, or the like, and is fixed to the ankle frame F3. The foot bottom contact portion C2 is attached to the ankle frame F3. Therefore, by causing the ankle frame F3 to slide with respect to the intermediate frame F2 whose position has been adjusted, the position of the foot bottom contact portion C2, which is the portion that contacts the foot bottom of the subject, can be adjusted. Thus, the foot bottom contact portion C2 can be adjusted to an appropriate position regardless of whether the subject is a large person or a small person.

[0058] The legrest member 900 is configured such that the fixed frame Fl does not support the ankle frame F3, the fixed frame Fl supports the intermediate frame F2, and the intermediate frame F2 supports the ankle frame F3. Therefore, the adjustment range of the position of the calf contact portion Cl and the adjustment range of the position of the foot bottom contact portion C2 are both large even without making the fixed frame Fl large (without lengthening the sliding direction of the fixed frame Fl). That is, the legrest member 900 can make the adjustment range of the position of the calf contact portion Cl and the adjustment range of the position of the foot bottom contact portion C2 both large with a compact configuration.

[0059] The position adjustment of the calf contact portion C1 and the position adjustment of the sole contact portion C2 can be performed, for example, by providing a sensor (e.g., a contact sensor, a piezoelectric sensor, or the like) that detects the contact of the sole of the subject with the sole contact portion C2 to the sole contact portion C2 and performing the position adjustment by the following steps.

[0060] First, the first drive portion D1 moves the intermediate frame F2 to a position where the intermediate frame F2 is maximally distanced from the fixed frame F1 (a position where the intermediate frame F2 is distanced from the seat portion 200), and the second drive portion D2 moves the ankle frame F3 to a position where the ankle frame F3 is maximally distanced from the intermediate frame F2 (a position where the ankle frame F3 is distanced from the seat portion 200). Next, with the intermediate frame F2 maximally distanced from the fixed frame F1, the second drive portion D2 moves the ankle frame F3 in a direction in which the ankle frame F3 approaches the intermediate frame F2 (a direction in which the ankle frame F3 approaches the seat portion 200). At the timing at which the sensor detects the contact of the sole of the subject with the sole contact portion C2, the second drive portion D2 stops the movement of the ankle frame F3 relative to the intermediate frame F2.

[0061] Thereafter, the first drive portion D1 moves the intermediate frame F2 in a direction in which the intermediate frame F2 approaches the fixed frame F1 (a direction in which the intermediate frame F2 approaches the seat portion 200). At this time, the second drive portion D2 moves the ankle frame F3 in a direction in which the ankle frame F3 is distanced from the intermediate frame F2, while the amount of movement of the intermediate frame F2 relative to the fixed frame F1 is made the same as the amount of movement of the ankle frame F3 relative to the intermediate frame F2. Thus, the position of the ankle frame F3 relative to the fixed frame F1 does not change.

[0062] Finally, based on the user operation on the operation portion 600 or the like that indicates that the calf contact portion C1 is in the appropriate position, the first drive portion D1 stops the movement of the intermediate frame F2 relative to the fixed frame F1, and the second drive portion D2 stops the movement of the ankle frame F3 relative to the intermediate frame F2.

[0063] In the direction from the knee of the subject toward the ankle and the opposite direction, it is preferable that the slidable length of the intermediate frame F2 relative to the fixed frame F1 be longer than the slidable length of the ankle frame F3 relative to the intermediate frame F2. That is, in the present embodiment, it is preferable that the linear motion stroke length of the electric linear motion mechanism including the motor M1 be longer than the linear motion stroke length of the electric linear motion mechanism including the motor M2. This is because, if the intermediate frame F2 is adjusted to the appropriate position according to the physique of the subject, the appropriate position of the ankle frame F3 relative to the intermediate frame F2 does not change much according to the physique of the subject.

[0064] In the present embodiment, a control unit (not shown) controls the first drive unit Dl and the second drive unit D2. The control unit (not shown) can also non-volatilely store the identification information (e.g., name information, nickname information, etc.) of the subject in association with the sliding position information of the intermediate frame F2 with respect to the fixed frame Fl and the sliding position information of the ankle frame F3 with respect to the intermediate frame F2. By adjusting the calf contact portion Cl and the sole contact portion C2 to appropriate positions and storing information indicative of the adjustment contents in the control unit (not shown) together with the identification information of the subject, the calf contact portion Cl and the sole contact portion C2 can be easily moved to appropriate positions based on the information stored in the control unit (not shown) the next time or later.

[0065] The chair-type massager 100 can perform extension therapy that stretches the ankle of the subject (performs plantar flexion of the ankle of the subject). Hereinafter, a specific example of the extension therapy that stretches the ankle of the subject will be described.

[0066] The leg rest member 900 further includes a calf restraint portion 1 that restrains the calf of the subject from moving in a direction from the knee of the subject toward the ankle with respect to the calf contact portion Cl.

[0067] In the present embodiment, as shown in Figure 4 The calf restraint portion 1 includes first to fourth air bags Al to A4. The first to fourth air bags Al to A4 and fifth to tenth air bags to be described later can also be used as therapy portions that perform therapy on the subject. Note that, Figure 4 The first to fourth air bags Al to A4 in FIG. 10 are illustrated in a contracted state. The first air bag Al is disposed on the right side of the right calf of the subject when the leg rest member 900 accommodates the lower leg of the subject. The second air bag A2 is disposed on the left side of the right calf of the subject when the leg rest member 900 accommodates the lower leg of the subject. The third air bag A3 is disposed on the right side of the left calf of the subject when the leg rest member 900 accommodates the lower leg of the subject. The fourth air bag A4 is disposed on the left side of the left calf of the subject when the leg rest member 900 accommodates the lower leg of the subject.

[0068] When the first air bag Al and the second air bag A2 become an inflated state, the right calf of the subject is sandwiched from both sides by the first air bag Al and the second air bag A2, and movement of the right calf of the subject in a direction from the knee of the subject toward the ankle with respect to the calf contact portion Cl is restrained. Note that, in the leg rest member 900, a partition wall Wl for partitioning a first accommodation space that accommodates the left lower leg of the subject and a second accommodation space that accommodates the right lower leg of the subject is provided, and therefore movement of the right calf of the subject in a direction from the knee of the subject toward the ankle with respect to the calf contact portion Cl can be restrained even in a structure in which either one of the first air bag Al and the second air bag A2 is not provided.

[0069] When the third airbag A3 and the fourth airbag A4 are inflated, they clamp the patient's left calf from both sides, preventing the left calf from moving relative to the calf contact point C1 in the direction from the knee towards the ankle. It should be noted that the leg support component 900 is provided with a partition wall W1 separating the first receiving space for the patient's left lower leg from the second receiving space for the patient's right lower leg. Therefore, even without the structure of either the third airbag A3 or the fourth airbag A4, it is possible to prevent the left calf from moving relative to the calf contact point C1 in the direction from the knee towards the ankle.

[0070] The leg pad component 900 also includes a foot inhibition part 2, which inhibits the movement of the patient's foot relative to the foot contact part C2 in a direction away from the foot contact part C2.

[0071] In this embodiment, such as Figure 4 As shown, the foot-inhibiting part 2 includes fifth to eighth airbags A5 to A8. It should be noted that... Figure 4 The fifth to eighth airbags, A5 to A8, are shown in their contracted state. Airbag A5 is positioned to the right of the patient's right ankle when the leg support component 900 accommodates the patient's lower leg. Airbag A6 is positioned to the left of the patient's right ankle when the leg support component 900 accommodates the patient's lower leg. Airbag A7 is positioned to the right of the patient's left ankle when the leg support component 900 accommodates the patient's lower leg. Airbag A8 is positioned to the left of the patient's left ankle when the leg support component 900 accommodates the patient's lower leg.

[0072] When the fifth airbag A5 and the sixth airbag A6 are inflated, they press against the instep of the recipient's right foot, inhibiting movement of the recipient's right foot relative to the foot contact point C2 in a direction away from C2. It should be noted that even without either the fifth airbag A5 or the sixth airbag A6, movement of the recipient's right foot relative to the foot contact point C2 in a direction away from C2 can still be inhibited.

[0073] When the seventh airbag A7 and the eighth airbag A8 are inflated, they press against the instep of the patient's left foot, inhibiting movement of the patient's left foot relative to the foot contact point C2 in a direction away from C2. It should be noted that even without either the seventh airbag A7 or the eighth airbag A8, movement of the patient's left foot relative to the foot contact point C2 in a direction away from C2 can still be inhibited.

[0074] The chair-type massager 100 further has a thigh portion restraining portion 3 that restrains the thighs of the subject from moving in a direction from the thigh base of the subject's thighs toward the knees with respect to the seat portion 200.

[0075] In the present embodiment, as shown in Figure 5 the thigh portion restraining portion 3 includes a ninth air bag and a tenth air bag 10. Note that, Figure 5 the ninth air bag A9 and the tenth air bag A10 in FIG. 10 are illustrated in a contracted state. The ninth air bag A9 is disposed to the right of the right thigh of the subject when the subject is seated on the seat portion 200. The tenth air bag A10 is disposed to the left of the left thigh of the subject when the subject is seated on the seat portion 200.

[0076] When the ninth air bag A9 and the tenth air bag A10 become an expanded state, the right and left thighs of the subject are sandwiched from both sides by the ninth air bag A9 and the tenth air bag A10, and the right and left thighs of the subject are restrained from moving in a direction from the thigh base of the subject's thighs toward the knees with respect to the seat portion 200.

[0077] In a first specific example of stretch therapy of the subject's ankles, the second drive portion D2 slides the ankle frame F3 in a direction away from the intermediate frame F2 in a state in which the calf portion restraining portion 1 restrains the movement of the subject's calf, and the foot bottom restraining portion 2 restrains the movement of the subject's foot bottom.

[0078] In a second specific example of stretch therapy of the subject's ankles, the second drive portion D2 slides the ankle frame F3 in a direction away from the intermediate frame F2 in a state in which the thigh portion restraining portion 3 restrains the movement of the subject's thighs, and the foot bottom restraining portion 2 restrains the movement of the subject's foot bottom.

[0079] In a third specific example of stretch therapy of the subject's ankles, the second drive portion D2 slides the ankle frame F3 in a direction away from the intermediate frame F2 in a state in which the position of the pad leg portion 900 with respect to the base frame F0 is adjusted so that the direction from the thigh base of the subject's thighs toward the knees and the direction from the subject's knees toward the ankles intersect, and the foot bottom restraining portion 2 restrains the movement of the subject's foot bottom. In this third specific example, the position of the pad leg portion 900 with respect to the base frame F0 is adjusted so that the subject's knees are bent, and thus, the seat portion 200 restrains the subject's knees from stretching when the second drive portion D2 slides the ankle frame F3 in a direction away from the intermediate frame F2. Therefore, it is possible to stretch the subject's ankles while keeping the subject's knees bent.

[0080] (Method for using ankle and calf stretch mode)

[0081] The touch panel or the like provided on the operation section 600 of the chair-type massager 100 is configured with items capable of performing prescribed treatment courses. By selecting the items, for example, an item of sliding the calf (the middle frame F2) forward and backward, an item of sliding the ankle (the ankle frame F3) forward and backward can be performed.

[0082] By selecting the item of sliding the calf (the middle frame F2) forward in the above, the calf (the middle frame F2) is slid forward in a state where the leg rest member 900 is rotated to be in the horizontal state. When a limit sensor that recognizes a limit value of a position where the calf (the middle frame F2) is slid forward recognizes a forward sliding limit of the calf (the middle frame F2) after a prescribed time elapses, the ankle (the ankle frame F3) is then slid forward.

[0083] By selecting the item of sliding the calf (the middle frame F2) backward in the above, the calf (the middle frame F2) is slid backward in a state where the leg rest member 900 is rotated to be in the horizontal state. When a limit sensor that recognizes a limit value of a position where the calf (the middle frame F2) is slid backward recognizes a backward sliding limit of the calf (the middle frame F2) after a prescribed time elapses, the ankle (the ankle frame F3) is then slid backward. Note that, when the calf (the middle frame F2) is slid backward, the ankle (the ankle frame F3) is also slid backward to perform a housing action when a force in the opposite direction is applied to the ankle (the ankle frame F3) by kicking the ankle of the subject by the subject after the limit sensor recognizes the limit of the backward sliding.

[0084] By selecting the item of sliding the ankle (the ankle frame F3) forward in the above, the ankle (the ankle frame F3) is slid forward in a state where the leg rest member 900 is rotated to be in the horizontal state. When a limit sensor that recognizes a limit value of a position where the ankle (the ankle frame F3) is slid forward recognizes a forward sliding limit of the ankle (the ankle frame F3) after a prescribed time elapses, the calf (the middle frame F2) is then slid forward.

[0085] By selecting the item of sliding the ankle (the ankle frame F3) backward in the above, the ankle (the ankle frame F3) is slid backward in a state where the leg rest member 900 is rotated to be in the horizontal state. When a limit sensor that recognizes a limit value of a position where the ankle (the ankle frame F3) is slid backward recognizes a backward sliding limit of the ankle (the ankle frame F3) after a prescribed time elapses, the calf (the middle frame F2) is then slid backward.

[0086] In addition, when the calf automatic treatment program is selected or the calf stretching program alone is selected, the pad leg member 900 is rotated to the horizontal state, and then the stretching is performed in the order of the calf (the middle frame F2), the ankle (the ankle frame F3) in the extension direction (the forward sliding direction). After the extension stretching (the forward sliding direction), the stretching is performed in the order of the ankle (the ankle frame F3), the calf (the middle frame F2) in the retraction direction (the rearward sliding direction). In the case of the retraction stretching (the rearward sliding direction), when the sensor detects the pressure or load associated with the foot bottom of the subject during the rearward sliding of the ankle (the ankle frame F3), the rearward sliding of the ankle (the ankle frame F3) is stopped from the detection position of the foot bottom, and the position of the foot bottom is fixed, and then the rearward sliding of the calf (the middle frame F2) is continued.

[0087] It should be considered that the above-described embodiments are illustrative and not restrictive, and it should be understood that the technical scope of the present application is not represented by the description of the above-described embodiments, but is represented by the claims, and belongs to all modifications within the meaning and scope equivalent to the claims.

[0088] For example, although the pad leg member 900 is configured to have a treatment unit (the roller R1, the first to tenth air bags A1 to A10, and the like) that treats the lower leg of the subject, the pad leg member 900 can be modified to have no treatment unit.

[0089] Further, the function of rotating the ankle from the heel can be added to improve the stretching effect of the plantar flexion and the dorsiflexion of the ankle.

[0090] (Other)

[0091] The chair-type massager 100 can also have an ankle stretching drive unit (not shown). The ankle stretching drive unit can perform treatment of stretching the ankle of the subject in the normal direction of the substantially planar calf contact portion Cl. Hereinafter, a specific example of the ankle stretching treatment of the subject will be described.

[0092] In the first specific example of the ankle stretching treatment of the subject, the ankle stretching drive unit (not shown) slides the ankle frame F3 with respect to the middle frame F2 in the normal direction of the calf contact portion Cl, that is, in the direction of pressing the calf from the back of the knee, in a state where the calf restraint portion 1 restrains the movement of the calf of the subject. This direction is the forward direction in the case where the pad leg member 900 is located at the initial position, and is the substantially upward direction in the case where the pad leg member 900 is rotated to the horizontal position. Note that at this time, the foot bottom restraint portion 2 can be in a state of restraining the movement of the foot bottom of the subject, or can be in a state of not restraining the movement of the foot bottom of the subject.

[0093] In the second embodiment of the ankle stretching therapy in which the thigh of the subject is stretched, the thigh stretching drive (not shown) slides the ankle frame F3 relative to the intermediate frame F2 in the normal direction of the calf contact portion CI. That is, in the direction in which the calf is pressed from the back of the knee. This direction is the forward direction when the leg rest member 900 is in the initial position, and is the substantially upward direction when the leg rest member 900 is turned to the horizontal position. Note that at this time, the foot bottom restraining portion 2 can be in the state in which the movement of the foot bottom of the subject is restrained, or can be in the state in which the movement of the foot bottom of the subject is not restrained.

[0094] In addition, the chair-type massager 100 can also be provided with a calf stretching drive (not shown). The calf stretching therapy in which the calf of the subject is pressed in the direction toward the shin can be performed by the calf stretching drive. Hereinafter, an embodiment of the first calf stretching therapy in which the calf of the subject is pressed in the direction toward the shin will be described.

[0095] In the first embodiment of the first calf stretching therapy in which the calf of the subject is pressed in the direction toward the shin, the thigh restraining portion 3 restrains the movement of the thigh of the subject, and the calf restraining portion 1 restrains the movement of the calf of the subject. In this state, the calf stretching drive (not shown) slides the intermediate frame F2 relative to the fixed frame Fl in the normal direction of the calf contact portion CI and in the direction from the calf of the subject toward the shin.

[0096] In the second embodiment of the first calf stretching therapy in which the calf of the subject is pressed in the direction toward the shin, the position of the leg rest member 900 relative to the base frame F0 is adjusted so that the direction from the hip of the thigh of the subject toward the knee intersects the direction from the knee of the subject toward the ankle. Then, in the state in which the calf restraining portion 1 restrains the movement of the calf of the subject, the calf stretching drive (not shown) slides the intermediate frame F2 relative to the fixed frame Fl in the normal direction of the calf contact portion CI and in the direction from the calf of the subject toward the shin. In this second embodiment, the position of the leg rest member 900 relative to the base frame F0 is adjusted so that the knee of the subject is in the bent state. For this reason, the seat portion 200 restrains the extension of the knee of the subject when the calf stretching drive (not shown) slides the intermediate frame F2 relative to the fixed frame Fl in the normal direction of the calf contact portion CI and in the direction from the calf of the subject toward the shin. Thus, the calf of the subject can be pressed in the direction toward the shin while the knee of the subject is kept in the bent state.

[0097] Further, the second calf stretching therapy of pulling the calf of the subject along the direction from the shin toward the calf can be performed by a calf stretching drive section (not shown). Hereinafter, a specific example of the second calf stretching therapy of pulling the calf of the subject along the direction from the shin toward the calf will be described.

[0098] In the first specific example of the second calf stretching therapy of pulling the calf of the subject along the direction from the shin toward the calf, the thigh restraining section 3 restrains the movement of the thigh of the subject, and the calf restraining section 1 restrains the movement of the calf of the subject. In this state, the calf stretching drive section (not shown) slides the intermediate frame F2 relative to the fixed frame Fl in the normal direction of the calf contact section Cl and in the direction from the shin of the subject toward the calf.
