As shown in FIG. 8, the air supply means 111 is composed of an air generator 112 composed of an air compressor and an air distributor 113 composed of a rotary valve connected to the air generator 112 by an air hose 112a. The air distributor 113 distributes the air generated by the air generator 112 to each of the bags 40 to 46 in an order determined by a predetermined massage mode, and supplies and discharges air to and from the bellows-like bag 80. It is supposed to be. One end of each of air hoses 40a to 47a is connected to a supply port (not shown) of the air distributor 113, and the other end of each of the air hoses 40a, 41a, 42a, 43a, 44a, and 45a is connected to the other end. The bag 40 for the back, the bag 41 for the back muscle, the bag 42 for the back, the bag 43 for the neck, the bag 44 for the thigh, and the bag 45 for the buttocks are connected, and the other end of the air hose 46a has four wires. It branches into branch hoses 46b, and leg bags 46 are connected to these branch hoses 46b, respectively. The other end of the air hose 47a is branched into two branch hoses 47b, and the bellows-like bag 80 is connected to these branch hoses 47b.
[0032]
The cross-sectional area of the supply port (not shown) to which the air hose 47a is connected, that is, the flow path cross-sectional area, is smaller than the cross-sectional area of the supply port (not shown) of the air distributor 113 to which the air hoses 40a to 46a are connected. The flow rate of air per unit time to the bellows-like bag 80 is set to be smaller than the other bags (the waist bag 40, the back bag 41, the back bag 42, the neck bag 43). , The leg bag 46, the thigh bag 44, the buttocks bag 45, and the leg bag 46) are set to be smaller than the air flow per unit. By this,When the supply of air to the bellows-like bag 80 is started, the bellows-like bag 80 expands slowly, that is, slowly.Stretch,The forward movement of the movable platform 70 of the leg rest 50 is slow, that is, at a slow speed.Because it ’s doneThis facilitates the positioning operation for positioning the leg of the leg bag 46 to a desired treatment portion. That is, when the movable table 70 is located at a desired position of the leg of the leg bag 46, the air supply to the bellows-like bag 80 is performed by operating the air supply / exhaust button (not shown) of the input means 116 described later. Stop the movable table 70Stop. At this time,If the moving speed of the movable base 70 is high, the stop timing may be slightly shifted, for example, if the timing is delayed.,The movable table 70 passes through the desired position of the treatment target.,Accurate positioning is no longer possibleA situation occurs. However, these situationsAs described above, it can be prevented by slowing down the moving speed of the movable base 70 and moving it.
[0033]
The air generating means 112 and the air distributor 113 are controlled by a control means 115 comprising a microcomputer or the like. The control means 115 is operated by operating the operation buttons (not shown) from the input means 116 comprising a remote control device having operation buttons (not shown) removably stored in the storage section 3 provided on the chair body 2. Massage mode setting signal, start signal, stop signal, etc.InputIt has become. The various massage modes include a waist bag 40, a back bag 41, a back bag 42, a neck bag 43, a buttocks bag 45, a thigh bag 44, and a leg bag 46. A whole body massage mode in which the whole body is massaged according to a predetermined order and a predetermined inflation time, the waist bag 40, the back muscle bag 41, the back bag 42 and the neck bag 43 are moved in a predetermined order and a predetermined time. Upper body massage mode in which the upper body is massaged according to the inflation time, bag for thigh 44AndLower body massage mode in which the lower back body is massaged in accordance with a predetermined order and a predetermined inflation time for the buttocks bag 45 and the leg bags 46, the waist bag 40, the back muscle bag 41, the back bag 42, and the neck In a well-known massage mode such as a point massage mode in which each of the bag body 43, the thigh bag body 44, the buttocks bag body 45, and the leg bag body 46 is independently expanded and contracted to massage each of the treatment target parts individually. is there.
The control means 115 executes the massage mode when the user inputs a desired massage mode from the input means 116, and executes the respective bag bodies in accordance with the order and the expansion / contraction time determined by the massage mode. The air generating means 112 and the air distributor 113 are controlled so as to supply and exhaust air to and from 40 to 46.
[0034]
The control means 115 executes the massage mode when the user inputs a desired massage mode from the input means 116, and executes the respective bag bodies in accordance with the order and the expansion / contraction time determined by the massage mode. The air generating means 112 and the air distributor 113 are controlled so as to supply and exhaust air to and from 40 to 46.
[0035]
The input means 116 is provided with an air supply / exhaust button (not shown) for inputting a supply / stop signal of air to the bellows-shaped bag 80. The air supply / exhaust button is operated to operate the bellows-shaped bag. The movable table 70 is moved in the front-rear direction with respect to the fixed table 60 by supplying and discharging air to and from the fixed table 60.
[0036]
Next, the operation of the massage machine 1 will be described.
[0037]
First, a case in which the leg mounting table 50 is used in a state where it is lowered downward will be described. In this case, the operating lever 106 is set to the position shown by the two-dot chain line in FIG. 5, and the back is seated on the seat portion 20 and the back is placed on the back portion 30. When the start button is operated, the control means 115 executes the massage mode to perform a desired massage.
[0038]
Next, a case where the leg placement table 50 is used in a state where it is positioned upward will be described. In this case, the distal end of the operating lever 106 is gripped and rotated clockwise from the position indicated by the two-dot chain line in FIG. 5 to the position indicated by the solid line in FIG. By the operation of the operation mechanism 100 described above by the rotation operation of the operation lever 106, the leg mounting table 50 is pushed up to the position shown by the solid line in FIG. After sitting on the seat 20 and resting the back on the backrest 30 and placing the legs on the mounting portion 71 of the leg mounting table 50, and then setting a desired massage mode from the input means 116, When the start button is operated, the control means 115 executes the massage mode to perform a desired massage.
[0039]
Then, in this case, when the leg bag 46 disposed on the placing portion 71 has a positional relationship that does not correspond to the desired treatment target due to the difference in physique, for example, the leg bag 46 is moved from the treatment target. If it is also located on the side of the seat 20, the air supply / exhaust button (not shown) of the input means 116 is operated so as to supply air to the bellows-like bag 80. Then, supply of air from the air distributor 113 to the bellows-like bag 80 is started under the control of the control means 115, and the bellows-like bag 80 gradually expands or expands. The user gradually moves forward and the leg bag 46 gradually approaches the position corresponding to the treated portion, so that the user presses the air supply / exhaust button when the leg bag 46 corresponds to the treated portion. Operate to stop the air supply. As a result, the control means 115 controls the air generation means 112 and the air distributor 113 to stop the air supply. Then, when the air supply is stopped, the bellows-like bag 80 is maintained in an extended state by the supplied air, so that the movable table 70 moves forward with respect to the fixed table 60 and the leg bag 46 is moved. It is maintained in a state that accurately corresponds to the treatment section.
[0040]
Then, after the leg bag 46 accurately corresponds to the treatment target, a desired massage mode including the operation of the leg bag 46 is set from the input means 116, and then the start button is operated. The means 115 executes the massage mode to perform a desired massage.
[0041]
Further, for example, when the leg bag 46 is located farther from the seat portion 20 side than the treatment section, the air supply / exhaust button (not shown) of the input means 116 is used to exhaust air from the bellows-like bag 80. To operate. Then, the exhaust of air from the bellows-like bag 80 through the air distributor 113 is started under the control of the control means 115, and the bellows-like bag 80 gradually contracts due to the urging force of the coil spring 90 in the compression direction. Due to the contraction, the movable base 70 gradually moves rearward with respect to the fixed base 60, and the leg bag 46 gradually approaches a position corresponding to the treated portion. When the air supply / exhaust button is operated so as to stop the air exhaust when corresponding to the treatment section, the control means 115 controls the air generating means 112 and the air distributor 113 to stop the air exhaust. When the evacuation of the air is stopped, the extended state is maintained by the remaining amount of air exhausted from the bellows-like bag body 80, so that the movable table 70 moves backward with respect to the fixed table 60 and The bag 46 is maintained in a state that accurately corresponds to the treatment target. After the desired massage mode including the operation of the leg bag 46 is similarly set from the input unit 116, when the start button is operated, the control unit 115 executes the massage mode to perform the desired massage. is there.
[0042]
In addition, the supply and exhaust of air when moving the movable table 70 is performed because the flow rate of air per unit time from a supply port (not shown) for supplying and exhausting air to and from the bellows-shaped bag body 80 is small. Since the moving speed is slow, the positioning of the leg bag body 46 to the treatment portion can be accurately and easily performed.
[0043]
As described above, the massage machine 1 has a configuration in which the movable table 70 is moved relative to the fixed table 60 by the bellows-like bag body 80 that expands and contracts by the supply and exhaust of air from the air supply unit 111. Because of the simplicity, a failure or the like hardly occurs even when used for a long time, and the cost can be reduced.
[0044]
Further, since the moving means is constituted by the bellows-like bag 80, the length of extension, that is, the moving range of the movable base 70 can be increased.
[0045]
In addition, since the maximum moving length of the movable table 70 with respect to the fixed table 60 is smaller than the free length of the bellows-shaped bag body 80, that is, the length in the free state, the movable table 70 is the largest with respect to the fixed table 60. Even in the moved state, since the bellows-like bag 80 does not extend beyond the length of the free state, no excessive stress is applied to the bellows-like bag 80 at the time of extension. Can improve the durability.
[0046]
The air supply means 111 constitutes a driving means for expanding / contracting or driving each of the bags 40 to 46 as a treatment element, and the amount of air supplied to each of the bags 40 to 46 per unit time is smaller than that of the bellows. Since the amount of air supplied per unit time to the bag-shaped body 80 is reduced, the speed at which the movable table 70 moves can be reduced, so that the movable table 70 can be moved slowly and the leg bag 46 is desired. The positioning can be easily performed in correspondence with the to-be-treated part.
[0047]
In the above-described embodiment, the treatment element is configured by a bag that expands and contracts by air supply and exhaust, but this is configured by a conventionally known protrusion, which is driven by a driving unit such as an electric motor. It may be driven.
[0048]
Further, in the above-described embodiment, the fixed base is configured by the fixed base 60 of the leg mounting base 50, and the movable base is configured by the movable base 70 that moves with respect to the fixed base 60. The fixed base may be configured by a frame member of the backrest portion 30, and the movable base may be configured by a base member provided with a neck bag as a treatment element that moves vertically in the frame member.
[0049]
Although the leg bag 46 is provided on both side walls of the mounting portion 71, it may be provided only on the bottom wall, or may be provided on both side walls and the bottom wall. It is good also as a structure which does.
[0050]
In the above-described embodiment, the driving bag is constituted by the bellows-shaped bag 80. For example, as shown in FIG. 9, a plurality of independent bags 180 formed in a substantially flat shape are stacked. In addition, the bag bodies 180 at both ends in the axial direction are disposed so as to be in contact with the first contact plate 65 of the fixed base 60 and the second contact plate 72 of the movable base 70, respectively. Alternatively, a branch hose 181 a branched from the air hose 181 may be connected to each of the air hoses 180, and the air hose 181 may be connected to the air supply unit 111.
