Description

  The present invention relates to a foot massage machine for massaging the sole of a user, and more specifically to a foot massage machine capable of enhancing the massage effect on the sole.

  2. Description of the Related Art A foot massage machine is known that performs acupressure massage on a sole of a user using a shiatsu that reciprocates along the longitudinal direction of the sole (see, for example, Patent Document 1).

The foot massage machine described in Patent Document 1 has a finger depressor that protrudes and protrudes from the bottom surface by a bottom airbag on the bottom surface of the concave portion into which the user's foot is inserted, and the finger depressor is disposed in the longitudinal direction of the concave bottom surface It can be moved. A side airbag is provided on the side surface of the recess.
JP 2005-58300 A

  In the above foot massage machine, with the degree of inflation of the left and right side airbags adjusted, the acupressure element protrudes and reciprocates so that any position on the inside, center, or outside of the sole can be moved from the heel to the toe. Shiatsu massage is applied. Further, during the shiatsu massage, the side airbag on the side surface of the recess is inflated and fixed in the recess so as not to lift the foot. The place where you feel most comfortable with the acupressure of the soles is the arch, and then the base of the finger.

  For this reason, for example, when massaging the inside of the sole from the heel side to the toe, a high pressure massage effect can be obtained when the acupressure element passes through the arch or at the base of the thumb. When you pass near the base of your thumb (generally, a person with a foot length of 26 cm, a position 2 to 3 cm away from the arch of the thumb), the acupressure will hit the bone near the base of your finger and you may feel pain You may feel uncomfortable. Similarly, even when the acupressure element passes through the center and the outside of the sole, the acupressure element may hit the bone near the base of the finger and may feel pain or feel uncomfortable.

  In order to avoid this problem, when the acupressure element is in a position where it feels uncomfortable, the bottom air bag may be depressurized to lower the height of the acupressure element. Since the movement stroke is increased, it takes a long time to reduce the height of the acupressure element so as not to feel uncomfortable, and there is a problem that a smooth massage cannot be performed.

  An object of the present invention is to provide a foot massage machine that enhances the massage effect and prevents the user from feeling pain or uncomfortable when performing shiatsu massage on the sole of the user.

In order to solve the above problems, the foot massage machine of the present invention is
A recess for inserting the foot of the user;
Acupressure that is deployed on the bottom of the recess and presses the sole of the user;
A drive mechanism for reciprocating the acupressure element in the longitudinal direction along the bottom surface of the recess;
A side airbag disposed on at least one of the left and right side walls of the recess;
Control means for controlling expansion and contraction of the side airbag and a driving mechanism;
In the foot massage machine with
The control means has a storage means for storing a specific position of the sole that the user feels uncomfortable, and the acupressure element is fixed in the longitudinal direction of the recess while being fixed so that the toes are not lifted by the inflated side airbag. When the acupressure element passes through the specific position, the air pressure of the side airbag is reduced.

    According to the foot massage machine of the present invention, when acupressure massage is performed on the sole of the user's foot from the heel to the toe, if the acupressure comes to a specific position on the sole that feels uncomfortable, the foot toe is fixed so that it does not lift up. Decrease the air pressure of the side airbag, and loosen the feet. Therefore, the user can avoid the pain and discomfort by moving the toe away from the acupressure element. Even if the amount of protrusion of the acupressure element is large enough to sufficiently press the arch, it is not necessary to take time to retract the acupressure element in order to avoid discomfort, and a smooth massage can be performed and the massage effect can be enhanced.

    In the case where the acupressure element protrudes from the bottom surface of the recess by the expansion of the bottom surface airbag arranged on the back side of the recess bottom surface and acupressures the sole, when the acupressure element passes through a specific position where it feels uncomfortable, By reducing the air pressure and pulling in the acupressure element as much as possible, it is possible to avoid more pain and discomfort.

  Also, if a specific position that makes the user feel uncomfortable according to the foot size is set, pain and discomfort can be avoided regardless of the foot size.

  Massage means are provided on the side and bottom surfaces of the first recesses (70) and (70) and the second recesses (74) and (74). In this embodiment, as shown in FIG. 9, as the massage means, the acupressure elements (85) and (85) are provided on the bottom surfaces of the first recesses (70) and (70), and the first recesses (70) and (70) are provided. Left and right side airbags (80) (80) on the left and right side walls, left and right side airbags (81) (81) on the left and right sides of the second recess (74) (74), and bottom airbag (82 ). The left and right side airbags (80), (80) deployed on the side surfaces of the first recess (70) are used when the user inserts the toes into the first recess (70). Is arranged so as to be sandwiched from the left and right.

  As shown in FIGS. 9 and 11, the acupressure element (85) can be projected and retracted from a long hole (72) formed long in the front-rear direction on the bottom surface of the first recess (70) and along the long hole (72). It is deployed so that it can move back and forth. Specifically, as shown in FIG. 11, the lower end of the acupressure element (85) is connected to the bottom airbag (83), and the bottom airbag (83) has left and right first recesses (70) (70). ) Are accommodated in the left and right cases (86) corresponding to the acupressure elements (85) and (85), and constitute a massage unit (86a). The left and right massage units (86a) are connected by a connection plate (87) and connected to the drive mechanism so that the massage unit (86a) can reciprocate back and forth along the first recess (70). .

  The drive mechanism is mainly composed of a motor (89). A screw cylinder (not shown) provided on the connection plate (87) is connected to a screw shaft (88) supported in parallel along the bottom surface of the first recess (70). ) Is connected to a motor (89) (see FIG. 9) via a speed reduction mechanism (89a).

  When the screw shaft (88) rotates, the connection plate (87) moves back and forth, and the acupressure element (85) moves along the elongated hole (72). 9 and 11 show a state where the acupressure element (85) has moved most forward and backward.

  Airbag (83) for inflating and retracting airbags (80), (81), (82) and shiatsu depressors (85) disposed in the first concave portions (70), (70) and the second concave portions (74), (74) on the left and right Are respectively connected to the piping, and the piping penetrates into the casing (51) of the reclining movable portion (50). Solenoid valves (13A) to (13D) (see FIG. 13) are connected to each pipe. Pipes extending from the solenoid valves (13A) to (13D) extend to the base portion (20) and are connected to the air pump (12). It should be noted that it is desirable to connect one or several pipes upstream of the solenoid valve to the air pump (12). Thereby, the number of piping which connects a reclining movable part (50) and a base part (20) can be reduced. When each solenoid valve (13A) to (13D) is opened, the compressed air from the air pump is supplied to the corresponding airbag to inflate, and when closed, the passage to the air pump is shut off and the corresponding airbag communicates with the atmosphere. Then, the air inside is exhausted and contracted. Further, airbags (80), (81), (82), and (83) are arranged in the left and right first recesses (70) and (70) and the second recesses (74) and (74), respectively. (80) and (81) are arranged on the left and right side walls of the recesses (70) and (74), respectively, and each of the plurality of airbags (80), (81), (82), and (83) respectively correspond. One solenoid valve (13A) to (13D) is operated simultaneously.

  All control of the foot massage machine (10) of the present invention is performed by the control means (90). As shown in FIG. 12, the control means (90) includes massage means, in this embodiment, an air pump (12) for inflating the airbags (80), (81), (82), and (83), and solenoid valves (13A) to (13D), a motor (89) for adjusting the position of the massage unit (86a) on which the acupressure element (85) and the airbag (83) are mounted, an operation unit (91), various programs, and a RAM storing a massage course (96), flash memory (97), etc. are connected. The control means (90) may include a RAM (96) and a flash memory (97).

  The operation unit (91) includes a foot size determination switch (94) for selecting a foot size in addition to various operation switches. The main body of the control means (90) has a built-in storage means (98) for storing a specific position where the user feels pain or feels uncomfortable when performing acupressure massage on the sole. This specific position is stored for each foot size determined by the foot size determination switch (94).

  In such a configuration, left and right foot tips are inserted into the left and right first recesses (70) and (70), and calves are inserted into the second recesses (74) and (74) to inflate and contract the side airbags (80) and (81). By doing so, press the foot and calf from the side to massage. Also, by inflating the bottom airbag (83), it is possible to apply acupressure massage by pressing the sole with the acupressure element (85), and by inflating the bottom airbag (82), the back of the calf Press to give a massage.

    Next, in the flowchart of FIG. 14, a case where massage is performed by driving the drive mechanism (motor (89)) while projecting the acupressure element (85) to move the acupressure element (85) from the heel to the toe. This will be explained based on. In this case, in order to increase the acupressure effect, the side airbag (80) is inflated and fixed to the first recess (70) so as not to be lifted by pressing the tip of the foot from the side.

When the sole is massaged from the heel side to the toe, a high massage effect can be obtained when the acupressure element (85) is located at the arch or the base of the finger, but it slightly approaches the arch side from the base of the finger. In the vicinity, the acupressure element (85) hits the bone near the base of the finger and may feel pain or uncomfortable. The specific position felt uncomfortable varies depending on the foot size. (For example, a person with a foot length of 26 cm feels uncomfortable in the position of the arch from 2 to 3 cm from the base of the thumb.)
In step 1, the foot size is determined by the foot size determination switch (94). Based on this determination, a specific position where the user feels uncomfortable according to the foot size stored in the storage means (98) is determined (step 2). The massage is started, and the movement from the heel to the toe starts with the acupressure element (85) protruding. (Step 3)
The current position of the acupressure element (85) is recognized, and it is determined whether or not the current position is a specific position where it feels uncomfortable (step 4). If it is the specific position, the side airbag (80) is decompressed and the bottom airbag (83) is also decompressed (step 6). Specifically, the solenoid valves (13A) and (13D) in the piping to each airbag (80) and (83) are closed, and each airbag (80) and (83) is communicated to the atmosphere. Is performed by exhausting the air.

    As a result, the force of fixing the toes from the side airbag (80) will be weakened, and the user will move the toes away from the shiatsu (85) by themselves to avoid pain and discomfort Can do. At the same time, the force of the bottom air bag (83) to project the acupressure element (85) is weakened and the amount of protrusion is reduced, so that it is possible to further avoid pain and discomfort.

  When a predetermined massage time elapses or an end command is issued from the operation unit (91) (step 7), the massage is ended.

    The current position of the acupressure element (85) is recognized by counting the output pulses of the motor (89) of the drive mechanism that drives the acupressure element (85) with a motor encoder (92) (see FIG. 12), and a predetermined reference point ( For example, it can be recognized by the number of counts from a limit switch (92a) etc. that is closest to the heel.

  The specific position where the user feels uncomfortable may be set by the user operating the operation unit (91) during the massage. Therefore, when the input part (93) for setting a specific position is provided on the operation part (91) and the acupressure element (85) is moving, the user feels uncomfortable or painful By operating the input unit (93), the control means (90) stores the uncomfortable position or the uncomfortable position range in the storage means (98), and in the subsequent massage operation, as described above and in FIG. Discomfort can be avoided.

  In addition, the specific position where the user feels uncomfortable is automatically detected by the foot size detection means, the specific position is calculated based on the detected foot size, and the calculated value is stored in the storage means (98). You may keep it. The size of the foot depends on the amount of protrusion of the acupressure element (85) when the acupressure element (85) is moved in the longitudinal direction of the first recess (70), the pressure change of the bottom airbag (83), It can be measured by a sensor.

  The side airbag (80) is provided on both the left and right side surfaces of the first recess (70). However, in order to prevent the tip of the foot from floating, it is provided on at least one side surface and is shared with the other side surface. Thus, it is possible to hold and hold the feet so that they do not rise.

  Also, the left and right side airbags (80) and (80) can be individually inflated, and the degree of expansion of the left and right side airbags (80) and (80) can be adjusted while the acupressure element (85) is moving from the heel to the toes. By changing, it is of course possible to arbitrarily change the movement locus of the acupressure element (85) from the center, the inner side, and the outer side of the sole.

  In the above embodiment, the left and right first recesses (70) and (70) and the second recesses (74) and (74) can massage the left and right legs (hereinafter, including the toes and calves) at the same time. However, there are cases where the user does not want to treat one leg. In this case (for example, when one leg is injured), the leg that does not want to be treated must be taken out of the massage machine. The airbag of the massage machine is normally located in the same place on both the left and right legs (for example, the bottom airbag (83) in the left first recess (70) and the right first recess (70)). The bottom air bag (83)) communicates to inflate and contract at the same time. If you massage with one leg out, the person who goes out is unloaded and the air on the side where the leg is in The degree of expansion increases compared to the bag, and on the contrary, the airbag on the side where the legs are put in does not sufficiently inflate and a good massage feeling cannot be obtained.

  Therefore, the right and left airbags can be controlled independently by interposing solenoid valves in the left and right airbag pipes that massage the left and right legs, respectively. The operation unit (91) is provided with a left / right selection switch (95) for selecting whether to treat the left and right legs independently, and this selection switch (95) can be used to massage only the selected leg alone. You can do it. In this case, the non-selected airbag is not inflated because the solenoid valve is closed. Setting a single leg massage with the selection switch (95) reduces the number of inflatable airbags, so if you leave the pump output alone, the amount of air supplied to the selected airbag to be inflated will be reduced. Since the pressure increases and the pressing pressure changes, the output of the pump is reduced by the number of airbags that stop inflation.

    FIG. 15 is a flowchart showing the operation at this time. If you want to massage only the right leg, go through step 1 Y and step 2 N, stop the left leg massage (step 5) and reduce the output of the air pump (12) (step 6) to massage the right leg Until the course is over (steps 7 and 8). If you want to massage only the left leg, stop the massage of the right leg through N in Step 1 (Step 3) and decrease the output of the air pump (12) (Step 4). Is performed until the course is completed (steps 7 and 8).

    Therefore, only the selected left and right legs can be massaged with the same pressing pressure as when both legs are massaged, and the pump output is also lowered, so that an energy saving effect can be expected.

  Also, if massage is performed with the left and right legs of the user not inserted in the correct positions of the first recess (70) (70) and the second recess (74) (74), points that are not intended by the designer This will cause pain and discomfort, so there will be leg detection sensors that detect whether the left and right legs are inserted in the correct position. You can also stop the massage on the other leg.

    As the leg detection sensor, as shown by the dotted line in FIG. 9, the pressure sensor (100) provided in the portion of the first recess (70) (70) in contact with the heel can be exemplified, and the foot tip is placed at a correct position. Detect if it is. Further, a pressure sensor (100) may be provided at a portion of the second recess (74) (74) where the calf contacts, so as to detect whether the calf is placed at a correct position.

    FIG. 16 shows a flowchart for operating the leg detection sensor. If the right leg is not detected in the correct position (N in Step 1), the right leg massage is stopped (Step 2). If the left leg is not detected in the correct position (N in Step 3), the left leg is massaged. Is stopped (step 4). At this time, when the massage of each leg is stopped and the pump output is reduced as in FIG. 15, the massage can be performed with the same pressing pressure as that for both legs. Massage is performed on the left and right legs placed at the correct positions until the course is completed (steps 5 and 6).

    By the way, as shown in FIG. 13, when a plurality of airbags (80), (81), (82), and (83) are inflated by one pump (12), the pressure of the airbag (pressing pressure on the human body) is: The air bag that is adjusted by adjusting the output of the pump (12) is selected by opening and closing the solenoid valves (13A) to (13D). If the user has set the pump output weak to reduce the pressure of the airbag on the human body, it takes time until the airbag inflates, and a predetermined pressure is applied to the human body after the airbag starts to inflate. It is considered that smooth massage cannot be performed due to the blank time until.

    For this reason, even if the pressure of the airbag is set low, the pump output is maximized or increased for a predetermined time from the start of inflation of the airbag, and the airbag is inflated with the pump output set in the middle. As a result, the blank time from the start of the inflation of the airbag to the application of a predetermined pressing force to the human body can be shortened, and a massage with a desired strength can be performed in a short time.

    The timing at which the pump output is switched from the maximum (or increased) to the predetermined output, that is, the predetermined time is individually set according to the size of the airbag to be inflated and the number of airbags. The larger the number of airbags and the larger the airbag, the longer the predetermined time is set.

    In addition, since the airbag is not sufficiently along the human body (leg) at the start of the massage and the treatment may feel weak, the user tends to set a stronger massage. However, as treatment progresses, the airbag will follow the shape of the human body, and on the contrary, it may sometimes feel stronger than desired.

    Therefore, it is preferable to set the pressure of the airbag to be stronger at the start of massage and to be weakened as the treatment progresses. For example, in the case of a massage program in which the massage time for one massage is usually about 15 minutes and a massage pattern of several minutes is set as one cycle and this is repeated several times, the first cycle is set to a higher pressure and the second cycle Thereafter, the air pressure is lowered by about 10% with respect to the air pressure in the first cycle. As a result, the sensory strength can be made almost constant from the start to the end of the massage.

  The above-described foot massage machine (10) can be used alone as a foot massage machine, or a seat portion on which the user sits, and a back end of the seat portion that hits the back of the user It can also be mounted on the legs of a chair-type massage machine provided with a backrest and legs that are provided at the front end of the seat and massage the calf and toes of the user.
