Utility Model Content

[0005] Issues to be Solved by Utility Models

[0006] However, in most massage machines, a leg rest for supporting the lower limbs of the patient is connected to the front end of the seat on which the patient sits. Therefore, when the patient stands up from the seat, the upper part of the lower leg of the patient easily abuts against the upper end of the leg rest. As a result, the patient feels uncomfortable, such as difficulty in standing up, and sometimes feels that the convenience is poor.

[0007] In view of the above situation, the utility model aims to provide a massage machine capable of improving convenience.

[0008] Solutions to Solve Problems

[0009] In order to achieve the above-mentioned purpose, a massage machine of one embodiment of the utility model comprises a seat, a frame and a leg rest. The seat supports the buttocks and thighs of a seated person being treated. The frame is erected on both sides of the seat in the left and right directions to support the seat. The leg rest supports the calf of the person being treated. The upper end of the leg rest is supported by the frame. By rotating at least a part of the seat around a seat rotation axis extending in the left and right directions, the front end of the seat can be located below the rear end of the seat. The leg rest has a wall and an escape portion. The wall is arranged on the rear side of the lower part of the calf of the person being treated and contacts the lower part. The escape portion is composed of a space arranged above the wall.

[0010] Further features and advantages of the present invention will become more apparent from the following embodiments.

"Leg" refers to the part from the hip joint to the lower side (i.e., the toes of the foot). "Lower limb" refers to the part from the hip joint to the ankle. "Thigh" refers to the part from the hip joint to the knee. "Calf" refers to the part from the knee to the ankle. "Calf" refers to the bulging part at the back of the calf.

[0027] <1-1. Massage machine 100>

[0028] The massage machine 100 includes a seat portion 1 , a backrest portion 2 , a treatment unit 3 , a pair of left and right upright portions 4 , a pair of left and right armrest portions 5 , and a leg rest 6 .

[0029] The patient is seated on the seat 1. The seat 1 supports the buttocks and thighs of the patient. The seat 1 is supported by a frame 7 described later. By rotating the seat 1 around the seat rotation axis Ja1, the front end of the seat 1 can be located below the rear end of the seat 1. For example, in the present embodiment, the rear end of the seat 1 is axially supported by the frame 7, and can be rotated around the seat rotation axis Ja1 by the actuator 10 for the seat 1 (see Figure 3 It should be noted that the seat rotation axis Ja1 extends in the left-right direction and passes through the connection portion between the seat 1 and the frame 7 .

[0030] When the patient stands up from the seat 1, the seat 1 rotates by contraction of the actuator 10 for the seat 1, and the front end of the seat 1 is located below the rear end. As a result, the seat 1 is tilted forward and downward when viewed from the left and right directions. Therefore, the patient can easily move the center of gravity forward, thereby assisting the patient to stand up.

[0031] In the present embodiment, the front end of the seat 1 can be moved to a position lower than the rear end of the seat 1 by the rotation of the seat 1 around the seat rotation axis Ja1. In this way, compared with a structure in which the rear end of the seat 1 is moved to a position higher than the front end, the front end of the seat 1 can be easily lowered by utilizing gravity. Therefore, compared with a structure in which the rear end is moved up and down, the front end of the seat 1 can be easily lowered.

[0032] However, this example does not exclude a structure in which the rear end of the seat 1 can move to a position above the front end. For example, the front end of the seat 1 can also be axially supported by the frame 7. In addition, the rear end of the seat 1 can be rotated around a rotation axis that passes through the front end of the seat 1 and is parallel to the left and right direction by the actuator 10 for the seat 1.

[0033] The backrest 2 extends from one of the buttocks (or waist) and the head of the person being treated leaning on the backrest 2 to the other direction as the long side direction and from left to right as the short side direction. The backrest 2 supports the head, trunk (such as shoulders, waist and spine) of the person being treated. The lower end of the backrest 2 is arranged at a position farther back than the seat 1 and is axially supported on the frame 7. The backrest 2 can rotate around the backrest rotation axis Jb. It should be noted that the backrest rotation axis Jb extends in the left and right directions and passes through the connection part between the backrest 2 and the frame 7. The backrest 2 can be tilted backward from the standing state or rotated forward from the backward tilted state by rotating around the backrest rotation axis Jb. For example, when the person being treated stands up from the seat 1, the backrest 2 can rotate forward. In this way, the body of the person being treated can be pressed forward by the backrest 2, thereby assisting the person being treated to stand up.

[0034] The treatment unit 3 can treat the torso and neck of the person being treated. The treatment unit 3 is arranged on the backrest 2 (see Figure 1 The treatment unit 3 can move in a direction perpendicular to the left-right direction along the backrest portion 2. For example, the treatment unit 3 is guided by a pair of left and right guide rails 31 provided on the backrest portion 2. The treatment unit 3 can be raised and lowered in the long side direction of the backrest portion 2.

[0035] The upright portions 4 are provided in an upright manner on both sides of the seat portion 1 in the left-right direction, and support the armrest portions 5 .

[0036] The armrests 5 are disposed on the upper part of the upright part 4. The pair of armrests 5 are disposed on both sides of the seat 1 in the left-right direction to support the forearms and hands of the person being treated. The pair of left and right armrests 5 are symmetrical to each other.

[0037] The leg rest 6 accommodates and supports at least the lower leg of the person being treated. When the front end of the seat 1 is not rotated to a position lower than the rear end, the leg rest 6 is arranged at a position lower than the front end of the seat 1. The upper end of the leg rest 6 is supported by the frame 7 (see Figure 2 as well as Figure 3 ).

[0038] In this embodiment, the legrest 6 can rotate around the legrest rotation axis Jc. It should be noted that the legrest rotation axis Jc extends in the left-right direction and passes through the connection between the legrest 6 and the frame 7. However, this example does not exclude a structure in which the legrest 6 cannot rotate.

[0039] <1-2. Main Part>

[0040] Next, refer to Figure 2 to Figure 5 The main parts of the chair-type massage machine 100 are described. Figure 2 to Figure 5As shown, the massage machine 100 further includes a frame 7. The frame 7 is erected on both sides of the seat 1 in the left and right directions, and supports the seat 1, the backrest 2, and the legrest 6. The upper part of the frame 7 is connected to the seat 1, the backrest 2, and the legrest 6, and the lower part is placed on the ground.

[0041] In addition, a wall portion 61 and an escape portion 62 are provided on the back of the leg rest member 6. The wall portion 61 extends in the up-down direction and the left-right direction. The wall portion 61 is arranged behind the lower part of the calf of the seated person to be treated, and contacts the lower part of the calf. The escape portion 62 is composed of a space arranged above the wall portion 61, and is arranged behind the upper part of the calf of the person to be treated. Therefore, the escape portion 62 does not contact the upper part of the calf.

[0042] Since the leg rest 6 has the avoidance portion 62 that does not contact the upper part of the calf of the person being treated, it is possible to prevent the upper part of the calf of the person being treated from contacting the leg rest 6 (especially the wall portion 61 thereof) when the person being treated stands up. Therefore, the person being treated can stand up without feeling any discomfort. Therefore, the convenience of the massage machine 100 can be improved.

[0043] In addition, the leg rest member 6 also includes a partition wall portion 63 and a pair of left and right side wall portions 64. The partition wall portion 63 protrudes forward from the left-right central portion of the front surface of the wall portion 61 and extends in the vertical direction. The partition wall portion 63 is arranged between the left and right calves of the seated person being treated. The pair of left and right side wall portions 64 protrude forward from the left-right both ends of the wall portion 61 and extend in the vertical direction.

[0044] like Figure 2-Figure 3 as well as Figure 5 As shown, the upper end of the side wall portion 64 may also be connected to the frame 7. Alternatively, as Figure 4 As shown, upper end portions of both sides of the wall portion 61 in the left-right direction may be connected to the frame 7 .

[0045] In addition, the leg rest 6 may also have a bottom plate portion on which the soles of the feet of the seated person can be placed. The bottom plate portion protrudes from the front surface of the wall portion 61 at the lower side of the wall portion 61 and extends in the left-right direction. However, this example does not exclude a structure in which the leg rest 6 does not have the above-mentioned bottom plate portion.

[0046] Next, in this embodiment, if Figure 2As shown, the escape portion 62 is a recessed portion. For example, the escape portion 62 is recessed downward from the upper end portion of the back of the leg rest member 6, and is open on the front surface and the rear surface. In addition, the escape portion 62 is arranged between a pair of left and right side wall portions 64 at the upper end portion of the wall portion 61. Alternatively, the escape portion 62 may be arranged between the partition portion 63 and the left side wall portion 64, and between the partition portion 63 and the right side wall portion 64 at the upper end portion of the wall portion 61. In this way, by arranging the recessed portion at the upper end portion of the back, the escape portion 62 can be simply configured.

[0047] However, this is not limited to the examples in this embodiment. Figure 4 As shown in FIG. 1 , the escape portion 62 may also be a space disposed above the upper end portion of the wall portion 61. Figure 4 As shown, by arranging a space that does not come into contact with the upper portion of the calf at the upper end portion of the wall portion 61, the escape portion 62 can be simply configured.

[0048] Next, in a state where the front end of the seat 1 is located below the rear end, at least the front side portion of the seat 1 (particularly the upper surface thereof) extends in a direction intersecting the escape portion 62 (see Figure 3 Thus, when assisting the patient to stand up, the front side of the thigh and the knee of the patient can be lowered downward to such an extent that the calf does not contact the wall 61 of the leg rest 6. Therefore, the patient can stand up comfortably without feeling any discomfort.

[0049] In particular, when the front end of the seat 1 is located below the rear end, the upper surface of at least the front portion of the seat 1 extends in a direction intersecting the escape portion 62. Thus, the person being treated can stand up more reliably and comfortably.

[0050] Preferably, if Figure 5 As shown, the front end of the seat 1 is accommodated in the escape portion 62 in a state where it is located below the rear end of the seat 1. In this way, the leg rest 6 (especially the escape portion 62) can be arranged near the front end of the seat 1. Therefore, the lower leg of the person being treated can be supported by the leg rest 6 in a comfortable state. However, this illustration does not exclude a structure in which the front end of the seat 1 is not accommodated in the escape portion 62.

[0051] In addition, it is preferable that the upper end of the partition wall portion 63 is arranged below the lower end of the escape portion 62 (see Figure 2 as well as Figure 4In other words, the upper end of the partition 63 can reach the lower end of the escape portion 62, or can be arranged at a position lower than the lower end of the escape portion 62. In this way, it is possible to prevent the upper end of the partition 63 from contacting the knees, thighs, etc. of the person being treated when the person stands up. Therefore, the person being treated can stand up without feeling any discomfort and without the partition 63 becoming an obstacle. However, this illustration does not exclude a structure in which the upper end of the partition 63 is arranged at a position higher than the lower end of the escape portion 62.

[0052] The upper end of the side wall portion 64 may reach the lower end of the escape portion 62 or may be arranged below the lower end of the escape portion 62. Alternatively, the upper end of the side wall portion 64 may be arranged above the lower end of the escape portion 62.

[0053] <1-3. Control system of massage machine 100>

[0054] Next, refer to Figure 6 A configuration example of a control system of the massage machine 100 will be described. Figure 6 This is a block diagram showing a control system that controls the operation of the massage machine 100 .

[0055] like Figure 6 As shown, the massage machine 100 further includes an operation unit 81 , a storage unit 82 , a control unit 83 , an actuator group 91 , a pump 92 , and an electromagnetic valve group 93 .

[0056] The operation unit 81 receives input operations from the patient and outputs signals based on the input operations to the control unit 83. The input operations include the rotation of the seat 1, the backrest 2, and the leg rest 6, the selection of the treatment plan, the intensity adjustment of the treatment, etc. The operation unit 81 is connected to the control unit 83 via a cable. The operation unit 81 can be assembled and disassembled relative to the bracket (the reference numeral is omitted). The bracket is fixed to the armrest 5 arranged on the left side of the seat 1.

[0057] The storage unit 82 is a non-transitory storage medium that holds stored information even when power supply is stopped. The storage unit 82 stores, for example, programs and data necessary for the control unit 83 to control the operation of the massage machine 100 .

[0058] The control unit 83 is disposed, for example, below the seat 1 and controls various parts of the massage machine 100 based on signals output from the operation unit 81. For example, the control unit 83 controls the driving and lifting of the treatment unit 3, the actuator group 91, the pump 92, and the electromagnetic valve group 93.

[0059] The actuator group 91 includes a plurality of actuators. For example, the actuator group 91 includes the actuator 10 for rotating the seat portion 1, an actuator (not shown) for rotating the backrest portion 2, and an actuator 60 for rotating the leg rest member 6.

[0060] The solenoid valve group 93 includes a solenoid valve provided in the airbag group (not shown). The pump 92 supplies air to the airbag group via the solenoid valve group 93. Each solenoid valve switches the expansion, maintenance of the inflated and deflated state, and deflation of the airbag group. In detail, the solenoid valve switches the connection / disconnection between the pump 92 and the airbag group. For example, when the pump 92 is connected to the airbag by the action of the solenoid valve, air is supplied to the airbag from the pump 92 via the solenoid valve. Thus, the airbag expands. In addition, the solenoid valve switches the connection / disconnection between the airbag group and the outside. For example, when the outside is connected to the airbag by the action of the solenoid valve, the airbag is opened to the outside via the solenoid valve. Thus, the air in the airbag is discharged and the airbag shrinks. In addition, when the airbag is neither connected to the pump 92 nor to the outside by the action of the solenoid valve, the amount of air in the airbag is maintained to maintain the inflated and deflated state of the airbag.

[0061] <2. Second Embodiment>

[0062] Next, refer to Figure 7 as well as Figure 8 A second embodiment will be described. Figure 7 It is a perspective view schematically showing a configuration example of a main part of a chair-type massage machine 100 according to the second embodiment. Figure 8 1 is a side view schematically showing a configuration example of the main parts of the chair-type massage machine 100 in the second embodiment. Figure 7 as well as Figure 8 In the figure, the outer decorations such as the cloth or leather cover and the cushioning material arranged on the surface are omitted. In addition, in order to facilitate the observation of the structure of the main parts, the treatment unit 3, the upright part 4 and the armrest part 5 are also omitted. Figure 8 , the chair-type massage machine 100 is viewed from the left side toward the right side.

[0063] In addition, in the second embodiment, the configuration different from that of the first embodiment is described. In addition, the same reference numerals are given to the same configuration parts as those of the first embodiment, and the description thereof may be omitted.

[0064] In the second embodiment, by rotating a portion of the seat 1 about the seat rotation axis Ja2 extending in the left-right direction, the front end of the seat 1 can be located below the rear end of the seat 1. Figure 7 as well as Figure 8 As shown, the seat portion 1 has a rear seat portion 11 and a front seat portion 12 .

[0065] The rear seat 11 and the front seat 12 are, for example, plate-shaped and extend in the front-rear direction and the left-right direction. The rear seat 11 supports the buttocks of the person being treated. Both ends of the rear seat 11 in the left-right direction are connected to the frame 7. The front seat 12 is arranged at a position closer to the front than the rear seat 11, and supports the thigh of the person being treated. In the present embodiment, both ends of the front seat 12 in the left-right direction are supported by the frame 7. Alternatively, and not limited to this example, the front seat 12 may also be supported by the front end of the rear seat 11. In addition, the front seat 12 can rotate around the seat rotation axis Ja2 through the actuator 10 for the seat 1. It should be noted that the seat rotation axis Ja2 extends in the left-right direction and passes through the rear end of the front seat 12.

[0066] Thus, when the patient stands up from the seat 1, the front end of the front seat 12 is rotated downward by the contraction drive of the actuator 10 for the seat 1. As a result, the front seat 12 is tilted forward and downward when viewed from the left and right directions. Therefore, the patient can easily move the center of gravity forward, thereby assisting the patient to stand up.

[0067] Preferably, when the front end of the front seat 12 is located below the rear seat 11, the front seat 12 (particularly, the upper surface thereof) extends in a direction intersecting the escape portion 62. In this way, when assisting the patient to stand up, the front side of the thigh and the knee of the patient can be lowered downward to such an extent that the calf does not contact the wall 61 of the leg rest 6. Therefore, the patient can stand up comfortably without feeling any discomfort.

[0068] In addition, it is preferred that the front end of the front seat 12 is accommodated in the escape portion 62 while being arranged at a position lower than the rear seat 11. In this way, the leg rest 6 (especially the escape portion 62) can be arranged near the front end of the front seat 12. Therefore, the lower leg of the person being treated can be supported by the leg rest 6 in a comfortable state. However, this example does not exclude a structure in which the front end of the front seat 12 is not accommodated in the escape portion 62.

[0069] <3. Preparation for the exam>

[0070] It should be considered that all points of the above-mentioned embodiments are illustrative rather than restrictive, and it should be understood that the technical scope of the present invention is not represented by the description of the above-mentioned embodiments but by the technical solution, including all changes within the meaning and scope equivalent to the technical solution.

[0071] For example, the massage machine 100 of the above-described embodiment includes the backrest portion 2 . However, the massage machine 100 is not limited to this example, and may not include the backrest portion 2 .
