Air bags that are inflated by the supply of compressed air from the air pump are placed on the left and right of the seat and backrest of the chair on which the user sits, and the left and right airbags are inflated alternately to twist and massage the upper body. 2. Description of the Related Art A massage machine is known (see, for example, Patent Document 1).
JP 2002-65779 A

  The time for inflating the air bag depends on the output of the air pump, and those with a small pump output will take time to inflate the air bag to the maximum, making it impossible to perform a sharp twist massage. . On the other hand, a pump with a large output is expensive and has a problem of noise.

  An object of the present invention is to provide a massage machine that can quickly twist a human body and perform a sharp twist massage even with a small pump output.

In order to solve the above problems, the massage machine of the present invention is
A pair of left and right human body receiving surfaces for receiving a human body, including an airbag that expands upon receiving compressed air supply from an air pump,
A pair of left and right airbags are held in a state of being inflated by a predetermined amount in advance, and one airbag is inflated and the other airbag is contracted to perform a twist massage on the human body. A pair of left and right airbags are held in a state where they are inflated by a predetermined amount.

  In the twist massage, it is preferable to repeat the operation of inflating one airbag and simultaneously contracting the other airbag alternately left and right.

    According to the massage machine of the present invention, the pair of left and right airbags are held in a state where they are inflated by a predetermined amount in advance, and from this state, one airbag is inflated and the other airbag is deflated. Since the human body is tilted by the sum of the movements, the amount of air that needs to be supplied to inflate the air bag is reduced, the time is shortened, and the body can be quickly tilted. Can be applied. Further, since the torsional massage is finished in a state where the pair of left and right airbags are inflated by a predetermined amount in advance, the time until the end can be shortened, and the pair of right and left airbags also functions as a cushion after the massage is finished.

  Hereinafter, the case where the massage machine of the present invention is applied to the chair type massage machine (10) will be described, but the present invention can also be applied to a mat type massage machine.

  The chair-type massage machine (10) is formed on an upper part of a pedestal frame (11), and a seat (12) on which a user sits and a back supported swingably on the rear end of the seat (12). It includes a waist part (20), armrest parts (14) and (14) formed on both sides of the seat part (12), and a leg rest (15) for massaging the calf of the user. The armrest (14) is provided with an operating device (17) for operating the massage machine (10) and performing various displays of the massage machine (10).

  The backrest (20), the seat (12), and the legrest (15) are inflated and deflated by supply and discharge of compressed air, respectively (30), (32), (40), (13), (16). ) Etc. are provided.

  As shown in FIGS. 1 and 2, the backrest part (20) has a pair of left and right treatment airbags (30) and (32) on the part (see FIG. 3) where the back (70) of the person to be treated hits. A pair of left and right head holding airbags (40) are disposed on the upper side of the treatment airbags (30) and (32) so as to sandwich a portion where the head (72) abuts (see FIG. 3). ) (40) is deployed.

  The treatment airbags (30) and (32) and the head holding airbags (40) and (40) are connected to an air pump (not shown). An electromagnetic valve is interposed in each pipe connecting the airbags (30), (32), (40), and (40) and the air pump. The electromagnetic valve is a so-called three-way valve, and each air bag (30) (32) and (40) (40) is compressed by the air pump in communication with the air pump by opening the electromagnetic valve interposed in each pipe. When air is supplied and inflated, the electromagnetic valve (not shown) closes, shutting off the communication between the airbag and the air pump, and connecting the airbag to the atmosphere to exhaust the air in the airbag and contract it. In addition, the air bag and the air pump are disconnected from each other, and the air bag is cut off from the atmosphere so that the air in the air bag is not exhausted. Each of the airbags (30), (32), (40), and (40) performs operations such as expansion and contraction independently by operation of the corresponding electromagnetic valve. Each electromagnetic valve can be controlled by the operation of the operating device (17) by the user or by a program.

  Similarly, the air bugs (13) and (13) of the seat (12) and the airbags (16) and (16) of the legrest (15) are connected to the air pump via electromagnetic valves and operate independently.

    The backrest (20), seat (12), and legrest (15) are covered with cushions, covers, etc., and the airbags (30) (32) (40) (13) (16) are externally I can't see. In addition, a pillow-like cushion (22) can be separately provided at a portion where the head (72) of the user hits.

  The treatment airbag (30) (32) can be formed in a substantially parallelogram or substantially rectangular shape extending along the longitudinal direction of the backrest (20), and the center (covered) of the backrest (20). It is arranged symmetrically with the spine of the user in contact with the spine). As shown in FIGS. 1 to 3, the treatment airbags (30) and (32) have a wide space on the upper side (head side) of the backrest portion (20), and the space becomes narrower toward the lower side. It is desirable to arrange in a V shape. By widening the distance on the shoulder side of the user, the upper body of the user can be greatly twisted during the torsional massage described later.

  The head holding airbags (40), (40) are arranged on the rear surface of the pillow-like cushion (22), and when inflated, as shown in FIGS. 4 (b) and 4 (c), The head (72) is inflated and held so as to prevent the head (72) from moving left and right and rotating.

  In the chair type massage machine (10) described above, when massage is started with the user sitting on the seat (12) and leaning on the backrest (20), a pair of left and right treatment airbags (30 ) (32) is supplied with a predetermined amount of compressed air at the same time, and is held in an expanded state, for example, about half of the maximum expansion as shown in FIG. 4 (a).

    When torsional massage is selected by operating the operating device (17) or by program control, the head holding airbags (40) and (40) are as shown in FIGS. 4 (b) and 4 (c). Inflates and holds the head (72) of the user. In this state, as shown in FIG. 4B, one of the treatment airbags (32) is inflated, and at the same time, the other airbag (30) is contracted. As a result, the upper right body is pushed forward and the upper left body is pulled backward, receiving a force in the left twisting direction centered on the spine, and torsional massage is performed.

    This twist massage is performed by holding a pair of left and right treatment airbags (30) and (32) in a state where they are inflated in advance by a predetermined amount, from which one airbag (32) is inflated and the other airbag (30) is contracted and the human body is tilted by the sum of the movements of both airbags (30) and (32), so the amount of air to be supplied to inflate the air bag (32) is reduced, and the time is also shortened. The body can be quickly tilted and a torsional massage can be given. Further, it is not necessary to increase the output of the air pump in order to shorten the time for expansion, a small air pump may be used, and the noise during operation of the air pump can be reduced.

    Next, one of the treatment airbags (32) that has been inflated is deflated, and at the same time, the other airbag (30) is inflated. As a result, as shown in FIG. 4 (c), the upper left body is pushed forward and the upper right half is pulled backward, receiving a force in the right twist direction around the spine, and in the opposite direction to FIG. 4 (b). Torsion massage is given.

    When performing this torsional massage, the head (72) of the user is held in a state in which it cannot be moved left and right and rotated by the head holding airbag (40) (40). Since the upper body is twisted around the spine from the shoulder to the waist while facing forward, it is an effective torsional massage. Particularly, since the treatment airbags (30) and (32) are arranged in a substantially V shape as shown in FIGS. 1 to 3, the shoulder of the user can be effectively pushed forward, A large twisting force can be applied to the upper body of the user.

    By repeating the above-mentioned alternate left and right twisting operations, the torsional massage centered on the spine is applied to the upper body of the user, and massage with high effects such as spinal correction, back (70) muscle and muscle relaxation, and stretching. Can receive.

    When the torsional massage ends, as shown in FIG. 4A, the pair of left and right treatment airbags (30) and (32) is finished with a predetermined amount of compressed air. Therefore, the time until the end can be shortened, and a predetermined amount of air is supplied to the pair of left and right airbags even after the end, so that it also functions as a cushion after the end of the massage.

      Although the treatment airbags (30) and (32) are arranged in a substantially V shape, they may be arranged parallel to the spine as shown in FIG. 5, and the head holding airbag (40) ( 40) may be omitted or not expanded.

  Of course, it is also possible to apply pressure massage by inflating both the treatment airbags (30) and (32) at the same time.

    In the above description, the case where a torsional massage is applied to the back by the treatment airbag (30) (32) provided in the backrest (20) is described, but the airbag (13) of the seat (12) It is also possible to apply a torsion massage from the buttocks to the thigh by making the same movement for (13).

    By the way, an air pump that supplies compressed air to an air bag may use one that has almost the same outer shape but a different output (for example, when two air pumps are purchased). The airbag must be inflated the same way no matter what pump is used. Therefore, a control board for each pump (here, pump A and pump B) is required. There is a problem in that it is necessary to prepare two types of control boards because it is not known which pump is being used during service.

    Thus, a method will be described in which even if there is only one control board, the pump used at the time of production and assembly is identified, and the airbag can be inflated in the same manner regardless of the pump used.

    FIG. 6 shows an electric circuit and piping diagram of a general air pump and airbag. Solenoid valves A, B, and C are interposed in passages between the air pump (A or B) (50) and the airbags A, B, and C, respectively. An AC voltage generated by the AC-DC converter (51) and the DC-AC converter (52) is applied to the commercial power supply AC100V to the air pump (A or B), and the air pump (A or B) is driven. . The air pump (A or B) is an electromagnetic pump.

    The control unit (53) for controlling the air pump (A or B) and the solenoid valves A, B, C, etc. is mainly composed of a microcomputer (54), and an operation for inputting various massage operation commands to the microcomputer (54). A unit (55) (key input and display in the figure), a display unit (56) for displaying an operation state, etc., and a memory (57) are connected. A voltage is applied to the control unit (53) from the AC-DC converter (51) through the power supply circuit (58) (shown as control unit power supply conversion in the figure). An operation signal is transmitted from the microcomputer (54) to the DC-AC converter (52), the air pump (A or B) (50), the electromagnetic valves A, B, C, etc., and applied to the air pump (A or B). The frequency and voltage value of the input voltage is adjusted, the output of the air pump (A or B) is adjusted, and the opening and closing of the solenoid valves A, B, and C are controlled.

    Here, the operation of discriminating the air pump (A or B) used during production assembly and adjusting the output of the air pump will be described with reference to FIG. If there is an input from the operation unit 55 (step 1... S1 in the figure below, the same applies hereinafter), it is determined whether or not it is a command for determining an air pump (step 2), and a command for determining an air pump. Otherwise, normal massage operation is started (step 3). If it is a command for discriminating the air pump, the air pump is driven to send air to the airbag (one of AC) (step 4).

    When the airbag is fully inflated, the current value of the air pump increases. The timing of increasing the current value is early when the output of the air pump is large, and late when the output is small. Here, the output of the pump is determined by dividing the timing at which the current value increases into three stages. If the time T from the driving of the air pump until the current value increases is A ≦ T <B, it is determined that the output of the air pump is large, and a signal that suppresses the output of the air pump is issued from the microcomputer (54). Is stored in the memory (57) (YES in step 5, step 8, step 11). If the time T is B ≦ T <C, it is determined that the output of the air pump is standard, a signal is output from the microcomputer (54) so that the output of the air pump is slightly increased, and this information is stored in the memory (57) ( NO in step 5, YES in step 6, step 9, step 11). If time T is C ≦ T, it is determined that the output of the air pump is small, and a signal is output from the microcomputer (54) to increase the output of the air pump, and this information is stored in the memory (57) (NO in step 6). , Step 7 YES, Step 10, Step 11). In step 7, if C ≦ T is not satisfied, it is determined that the air pump is abnormal, and all outputs are stopped. (NO in step 7, step 12, step 13). Here, A <B <C.

  In this way, at the time of production assembly, the size of the output of the used air pump is determined, and even if the output is different, the output of the air pump is adjusted so that the inflation speed of the airbag is the same, and this adjustment is performed. The condition is stored in the memory (57), and thereafter the output of the air pump is automatically adjusted based on the stored information. Therefore, a dedicated board is not required for each output of the air pump, and the board is shared. be able to. Therefore, serviceability can also be improved.
