To be disposed. The foot support 16 including the frame 16a is configured to be moved relative to the base 15a by the actuator 16c.

  Thus, the position of the foot support 16 can be adjusted by the actuator 16c with respect to the position of the base 15a, so that the position of the foot support 16 can be adjusted corresponding to the foot position which changes depending on the individual difference in the user's leg length. While being adjustable in the longitudinal direction of the leg, the foot support 16 can be moved to a standby position in close contact with the lower end of the leg support 15 in the non-use state.

  When using the massage machine, if the user puts the legs in the left and right grooves 15c of the leg support 15 and the legs in the foot receiving groove 16b of the foot support 16, the legs and feet can be massaged. Become. At this time, while the sole is in contact with the foot support portion 16, the foot support portion 16 is moved by the actuator 16c to a position where an excessive load is not applied from the foot, whereby the length from the knee to the lower portion of the user's leg The foot receiving portion 16 can be arranged at a position suitable for the above.

  Then, when the foot side air cells 79a, 79b, 79c, and 79d facing each other across the foot on both sides are inflated at a predetermined timing in the foot supporting state where the foot is attached to the foot receiving portion 16, the foot is pressed. Massage can be performed.

  Besides, the foot side air cells 79a, 79b, 79c, 79d press the foot from both sides by using the pressing force in the expanded state in addition to the direct massage function by the expansion and contraction accompanying the air supply and discharge. A function as holding means which holds the foot, suppresses unexpected movement of the foot, holds the foot properly by holding it on the foot receiving portion 16 and makes the foot movable with the foot receiving portion 16 relative to the base portion 15a Also have. In addition, as a means to hold | maintain this foot | leg, the mechanism etc. which moves a press piece mechanically and clamps a leg besides the thing using expansion and contraction of an air cell may be used, and it is not restricted to an air cell.

  In addition, the foot side air cell or the like is not necessarily operated from both sides of the foot to hold the foot, but the foot is pressed from only one side of the left and right side walls of the foot support facing each other. The foot may be pressed against the side wall on the opposite side of the receiving portion to obtain a sandwiching state.

  Thus, the foot receiving portion 16 capable of holding the foot, the base portion 15a supporting the foot receiving portion 16, and the treatment actuator 18 for moving the leg receiving portion 15b relative to the base portion 15a include the leg receiving portion 15b and It is used as a treatment means for moving the holding target portion of the leg held thereby relative to the foot.

  The foot support 16 holds the foot so as not to move in the direction in which the force acts on the force applied to the leg as the treatment actuator 18 moves the leg support 15b relative to the base 15a. It has become.

  By holding the foot by the foot support 16, the relative movement of the holding target site relative to the foot is realized with the movement of the leg support 15b, and the muscles and tendons of the calf as the holding target are moved for massaging Can produce the equivalent effect of

  Each air cell as a treatment mechanism, including the foot side air cells 79a, 79b, 79c, 79d, is grouped for each part where the air cell is present, such as legs and feet, and the air pump 70 is connected via a solenoid valve (not shown). Connected with

  The electromagnetic valve has a first port communicating with the air pump 70, a second port communicating with the air cell, and a third port communicating with the outside, and the first port according to control by the control unit 40. And the second port communicate with each other and the third port is closed to allow air supply from the air pump 70 to the air cell, and the second port and the third port communicate with each other and the first port A state in which the air cell air is exhausted to the outside, and a state in which the internal pressure of the air cell can be maintained by making the first port, the second port, and the third port not communicate with each other. This is a known three-way valve that can switch between three states, and a detailed description will be omitted.

  The air pump 70 and the solenoid valve form an air supply and discharge adjustment mechanism for each air cell, and the control unit 40 operates the air pump 70 and adjusts and controls the communication state of the solenoid valve to supply air for the desired air cell, It is a mechanism capable of exhausting or maintaining pressure, and inflating, contracting or maintaining the air cell in a predetermined expansion state. While the air cell is inflated, pressing force against the air cell contact portion of the body is generated, and the pressure is released at the time of contraction, so that it is possible to give a massage effect rich in change at each air cell position. When used, the nipping state and the non nipping state can be reliably switched.

  The operation unit 30 includes a large number of switches and a display unit for receiving various operation inputs to the massage machine, is detachably installed on the stand 31 on the side of the massage machine 1, and transmits the operation input related to massage to the control unit 40 It is The position of the stand 31 is adjustable in order to set the position of the switch of the operation unit 30 and the display unit to the optimum position for the user.

  The control unit 40 adjusts the other movable parts of the treatment mechanism and the massage machine to the state corresponding to the user based on the detection result obtained by executing the position detection of the body part of the user in advance. With respect to the treatment mechanism and other movable parts, control for performing appropriate treatment is performed on the basis of remote control operation, treatment contents recorded and set in advance, and information of the detection result.

  The control unit 40 is a computer including a CPU, a memory, an input / output interface and the like as its hardware configuration, and is a mechanism for operating the computer as the control unit 40 by a program stored in the memory or the like. The computer forming the control unit 40 may be a microcomputer integrally formed with a CPU, a memory, a ROM, and the like.

  The computer unit forming the control unit 40 is disposed in a predetermined space inside the massaging machine 1 directly under the seat portion 12 and the like, and can communicate with the operation unit 30. , The seat 12, the backrest 13, the actuators for tilting the leg support 15, the air pump 70, and the solenoid valve are electrically connected to each other, and for detecting the position of each part of the body of the user The operation of these drive mechanisms is controlled by the control signal output based on the program, and also by the control signal output based on the data of the massage set during the massage execution.

  In addition, the control unit 40 is also electrically connected to signal output means such as an encoder that outputs displacement amounts of the mechanical unit 50 and each actuator, and the state of the mechanical unit 50, the seat 12, the backrest 13, And while grasping the state such as the inclination of the leg support portion 15, the operation control of the drive means such as the motor and the actuator is performed.

  Besides this, the control unit 40 controls the mechanical unit 50 to detect the position of each part of the body of the user prior to the massage, as in a known massage machine, and sets the mechanical unit 50 from the initial position in the backrest 13 to the guide frame 13b. In the process of moving along with the user and moving the massaging balls 51 along the user, the change in pressure on the massaging balls 51 from the user side leaning on the backrest 13 and the inclination change of the massaging balls 51 are sequentially acquired. Based on the information, the user's shoulder position, spine line, waist position can also be detected.

  Next, in the massager according to the present embodiment, the operation process of each part for treatment for moving the holding target site of the leg relative to the foot will be described. As a premise, the main power source of the massage machine 1 is turned on while the user is seated on the massage machine 1 and the back is leaned against the backrest 13 and the legs are supported by the leg support 15, and the massage machine 1 is Starting up, preparation operations before massaging start such as weight and body shape detection of the user, reclining angle adjustment of the backrest 13 and the like are completed, and further, the user performs an operation instruction such as a massage course etc. While performing various massages, it is assumed that the control unit 40 is to perform operation control related to treatment based on the movement of the leg receiving unit.

  First, the leg receiving portion 15b of the leg supporting portion 15 moves from a position close to the seat portion to a side approaching the foot, and moves muscles of the calf as a holding target portion of the leg held by the leg receiving portion 15b. The operation process of the case will be described.

  Here, the control unit 40 operates the tilting actuator 17 in advance to tilt the leg support unit 15 supporting the user's leg, and the leg support unit 15 is in the initial position for treatment, that is, the leg It is assumed that the object to be held is brought to a predetermined tilt angle position of the leg support 15 suitable for treatment to move relative to the foot. Then, when the user causes the leg supporting portion 15 to support the leg on the leg supporting portion 16 and places the foot on the leg receiving portion 16, the foot receiving portion 16 receives position adjustment corresponding to the length of the leg. The bottom of the foot receiving groove 16b is in contact with the sole.

  The control unit 40 first inflates the foot side air cells 79a, 79b, 79c, 79d of the foot support unit 16 to start the operation of each mechanism portion of the leg support unit 15 in the initial position. Hold the back of the foot from the left and right of the foot and restrain it appropriately.

  When the foot side air cells 79a, 79b, 79c, 79d are fully inflated and the foot is properly held, the user attaches the sole to the bottom of the foot receiving groove 16b of the foot receiving portion 16. The foot is held and restrained by the foot support 16.

  Then, the control unit 40 controls the air cells 75 for the legs located on both sides of the legs at the leg support 15 simultaneously with or slightly after the expansion of the foot side air cells 79a, 79b, 79c, 79d of the foot support 16. Air supply to 76, 77, 78 is performed to expand each air cell (see FIGS. 5 and 4). With the expansion of the leg air cells 75, 76, 77, 78, the calf portion of the leg is sandwiched by the air cells from both sides, and is held and restrained by the leg receiving portion 15b.

  If the foot is deviated from the position where the foot should be originally located in the foot support 16, the foot holding process by the expansion of the foot side air cell proceeds and is completed in a state in which it is difficult to properly hold the foot There is a fear. However, when the foot side air cell is inflated to lightly hold the foot, the user holds the foot with the air cell in the correct holding position, for example, a portion from the instep to the foot side. Because it is less cramped and easier than pinching at other positions, it naturally tries to move the foot to a position where it is so pinched. That is, the press of the foot side air cell can prompt an action to correct the user's foot position.

  Based on this, if the leg air cells are allowed to expand after a while after the foot air cells are expanded (see FIG. 4), the foot air cells are sufficiently expanded before the leg air cells are expanded. At a stage where the user does not move the user, the user can move the leg or foot relative to the foot support 16 so that the position of the foot on the foot support 16 can be adjusted appropriately before the foot is held by the foot support 16. It can be

  With regard to such holding of the foot and the leg, the foot can be positioned at the correct position only by placing the foot on the foot support portion 16, and the foot can be arranged in an appropriate positional relationship with respect to the foot support portion 16 If it is easy to do so, the inflation of the foot side air cell and the leg air cell may be started at the same time, and the holding of the foot and the leg may be performed without time delay (see FIG. 5).

  When another air cell 79 for holding the thigh of the leg is disposed on both sides of the seat 12, the control unit 40 expands the air cell 75, 76, 77, 78 for the leg, and Air is supplied to the thigh air cell 79, which is inflated to perform pinching of the thigh (see FIG. 3).

  With the leg air cell fully expanded and the calf portion held and restrained, the control unit 40 operates the treatment actuator 18 of the leg support portion 15 to base the leg receiving portion 15b of the leg support portion 15 The portion 15a is moved little by little toward the end of the leg which is the side away from the seat 12 (see FIG. 7).

  In the case where it is possible to advance and complete the expansion and pressing of the air cell for the legs prior to the movement of the leg receiving portion 15b, and to securely hold the leg holding target portion in the very short time Alternatively, the control unit 40 can simultaneously start the expansion of the leg air cell and the movement of the leg receiving portion 15b relative to the base portion 15a, that is, the operation of the treatment actuator 18 (see FIG. 6). This point can be applied to the case where the expansion of the foot side air cell and the leg air cell is started at the same time, and the expansion and pressure of the foot side air cell and the leg air cell can both advance and complete quickly. In this case, the control unit 40 may simultaneously start the expansion of each air cell and the movement of the leg receiving portion 15b.

  By moving the leg receiving portion 15b away from the seat portion 12 with respect to the base portion 15a by the treatment actuator 18, the calf portion held by the leg receiving portion 15b is also moved, and the portion below the leg and the leg Also in the same manner as the leg receiving portion 15b, a force is applied to move it away from the seat.

  Here, since the foot abuts on the bottom of the groove of the foot receiving groove 16b in the foot receiving portion 16 and the foot is restrained from moving beyond the foot receiving portion 16, the direction away from the seat portion The foot is held stationary against the force of the foot, and the foot is maintained integrally with the foot receiving portion 16 in a non-moving state with respect to the base portion 15a.

  The muscle of the calf portion of the leg held by the leg receiving portion 15b is independent of the leg receiving portion 15b by the movement of the leg receiving portion 15b relative to the base portion 15a and the non-movement of the foot receiving portion 16 relative to the base portion 15a. The foot held by the foot support 16 is actually moved in the direction approaching it (see FIG. 7). Thus, the muscles of the foot support 15b and the calf move toward the foot held by the foot support 16 to move the muscles of the calf separately from the other lower legs and the foot. Therefore, it is possible to impart a treatment effect as if a person massaged moving muscles.

  Thereafter, the leg receiving portion 15b approaches its movement limit position as the movement toward the tip end of the leg proceeds. The control unit 40 determines whether the movement of the leg receiving unit 15 b has reached the movement limit.

  If it is determined that the movement limit has been reached, the control unit 40 causes the treatment actuator 18 to be in the operation stop state, and the movement of the leg receiving portion 15 b is stopped. As a result, excessive load is not applied to the legs beyond the preset treatment intensity of movement of the leg receiving portion. On the other hand, when the movement of the leg receiving portion 15b has not reached the limit position, the movement of the leg receiving portion 15b by the treatment actuator 18 is continued.

  At the same time as stopping the treatment actuator 18, the control unit 40 switches the electromagnetic valve of the air supply and discharge adjustment mechanism, contracts all the air cells in the expanded state by discharging the air, and releases the legs and the like from the holding state. Also, when the thigh is held by another air cell 79, if it is released from the held state by discharging the air also, the legs and feet will be released from restraint and return to the state of free movement.

  However, even after stopping the treatment actuator 18, the control unit 40 maintains the expanded state of each air cell for a while with the electromagnetic valve of the air supply and discharge adjustment mechanism maintained as it is for a predetermined time, and held by the leg receiving portion. A state in which a force toward the tip of the leg is applied to the calf muscle may be maintained for a predetermined time.

  And when the control part 40 performs the treatment concerning the movement of the said series of calf as one process of an automatic massage course, it transfers to the following massage and it is not an automatic course but is performed as an independent single treatment End the series of operation processes. However, if necessary, the control unit 40 operates the treatment actuator 18 in the reverse direction to move the leg receiving portion 15b in the direction toward the seat portion 12 after releasing the foot or the leg from the pinched state. Specifically, after the leg receiving portion 15b is returned to the position before the treatment, the actuator is put into the operation stop state again.

  Subsequently, the operation process in the case where the leg receiving portion 15b of the leg supporting portion 15 moves from the position closer to the foot to the side approaching the seat portion to move the muscle of the calf of the leg held by the leg receiving portion 15b explain.

  The control unit 40 operates the tilting actuator 17 as needed to tilt the leg support 15 supporting the user's leg, and the leg support 15 is in the initial position for treatment, that is, the leg The holding target site is moved to a predetermined tilt angle position of the leg support 15 suitable for treatment to move relative to the foot. The foot receiving portion 16 is previously adjusted in position corresponding to the length of the leg, and the bottom surface of the foot receiving groove 16b in the foot receiving portion 16 is in a state of being in contact with the sole.

  The control unit 40 first inflates the foot side air cells 79a, 79b, 79c, 79d of the foot support portion 16 to start the operation of each mechanism portion of the leg support portion 15, and the foot among the left and right legs Hold the instep part from the left and right and restrain appropriately.

  Then, the control unit 40 controls the air cells 75 for the legs located on both sides of the legs at the leg support 15 simultaneously with or slightly after the expansion of the foot side air cells 79a, 79b, 79c, 79d of the foot support 16. Air supply to 76, 77, 78 is performed to expand each air cell (see FIGS. 5 and 4). With the expansion of the leg air cells 75, 76, 77, 78, the calf portion of the leg is sandwiched by the air cells from both sides, and is held and restrained by the leg receiving portion 15b.

  When another air cell for holding the thigh of the leg is disposed on both sides of the seat 12, the control unit 40 inflates the leg air cells 75, 76, 77, 78, and then the thigh Air is supplied to the air cell 79 for a part, and this is inflated to perform pinching of the thigh (see FIG. 3).

  With the leg air cell fully expanded and the calf portion held and restrained, the control unit 40 operates the treatment actuator 18 of the leg support portion 15 to base the leg receiving portion 15b of the leg support portion 15 With respect to the part 15a, it is separated from the foot and moved little by little to the side approaching the seat part 12 (see FIG. 8).

  By moving the leg receiving portion 15b to the side closer to the seat portion 12 with respect to the base portion 15a, the calf portion held by the leg receiving portion 15b is also moved, and the leg receiving portion below the leg and the leg As in the case of the portion 15b, a force is applied to move it in the direction approaching the seat portion.

  Here, the foot is held between the foot side air cells 79a, 79b, 79c, 79d in the foot support portion 16, and the foot does not move in the direction of separating the foot sole from the bottom of the foot receiving groove 16b. Since the foot is restrained, the foot is kept stationary against the force in the direction of approaching the seat, and the foot is maintained integrally with the foot support 16 with respect to the base portion 15a. Further, when the thigh air cell 79 is inflated to hold the thigh, even if a force is applied to the leg along with the movement of the leg receiving portion 15b, the thigh is held and restrained and does not move Thus, the entire leg does not move relative to the seat 12 as the leg receiving portion 15b moves, and the movement of the leg held by the leg receiving portion 15b is limited to only the holding target portion of the leg, The treatment effect by relative movement of this part relative to the other part of the leg can be reliably produced.

  The muscle of the calf portion of the leg held by the leg receiving portion 15b is independent of the leg receiving portion 15b by the movement of the leg receiving portion 15b relative to the base portion 15a and the non-movement of the foot receiving portion 16 relative to the base portion 15a. The foot held by the foot support 16 is actually moved away from the foot (see FIG. 8). Thus, the muscles of the foot support 15b and the calf move away from the foot held by the foot support 16 to move the muscles of the calf separately from the other legs and feet below it. Thus, the site between the calf and the foot can be efficiently extended to provide a treatment effect as if stretching was performed.

  Furthermore, the thighs of the legs held by the thigh air cell 79 are at rest against the muscles of the moving leg receiving portion 15b and the calf, and relative movement of the leg receiving portion 15b is allowed relative thereto. Only the muscles of the calf held by the foot rests 15b can be moved locally with respect to the upper part of the held stationary leg. In this way, the muscles in the calf can be moved to give the effect as if a person massaged moving muscles.

Thereafter, the leg receiving portion 15b approaches its movement limit position as the movement toward the seat portion progresses. The control unit 40 determines whether the movement of the leg receiving unit 15 b has reached the movement limit.
If it is determined that the movement limit has been reached, the control unit 40 causes the treatment actuator 18 to be in the operation stop state, and the movement of the leg receiving portion 15 b is stopped. As a result, there is no possibility that excessive load is applied to the leg beyond the preselected and set treatment intensity. On the other hand, when the movement of the leg receiving portion 15b has not reached the limit position, the movement of the leg receiving portion 15b by the treatment actuator 18 is continued.

  At the same time as stopping the treatment actuator 18, the control unit 40 switches the electromagnetic valve of the air supply and discharge adjustment mechanism, contracts all the air cells in the expanded state by discharging the air, and releases the legs and the like from the holding state. Also, when the thigh is held by another air cell 79, if it is released from the held state by discharging the air also, the legs and feet will be released from restraint and return to the state of free movement.

  However, even after stopping the treatment actuator 18, the control unit 40 maintains the expanded state of each air cell for a while with the electromagnetic valve of the air supply and discharge adjustment mechanism maintained as it is for a predetermined time, and held by the leg receiving portion. A state in which a force toward the seat side is applied to the muscles of the calf may be maintained for a further predetermined time.

  Then, when the treatment related to the movement of a series of calf muscles is performed as one process of an automatic massage course, the control unit 40 shifts to the next massage and performs not as an automatic course but as an independent single treatment If this is the case, the series of operation steps are ended. However, if necessary, the control unit 40 operates the treatment actuator 18 in the reverse direction before moving the leg receiving portion 15b in a direction approaching the foot after releasing the foot or the leg from the pinched state, and the final Then, after returning the leg receiving portion 15b to the position before the treatment, the actuator is put into the operation stop state again.

  Thus, in the massage machine according to the present embodiment, the leg supporting portion 15 for supporting the leg on the front side of the seat 12, the base 15a attached to the seat 12, and the leg receiving portion 15b movable relative thereto And a foot receiving portion 16 as a foot holding means for holding the foot against the force acting when the leg receiving portion 15b is moved by the treatment actuator 18, and is held by the leg receiving portion 15b. The calf portion as the holding target portion of the leg is moved relative to the foot by the treatment means consisting of the base portion 15a, the treatment actuator 18 and the foot support portion 16 to cause the calf portion to move relative to the other portion. This ensures that only the calf can be moved locally with respect to the calf around the leg, and the muscles located in the calf can be It is possible to impart remarkable changes such as tin on the legs, and the effects of treatment equivalent to massage etc. accompanying such changes are clearly obtained, and other parts such as the foot are moving according to the movement of the calf. You can experience new effects that are different from situations like this, and you can further enhance the relaxing feeling of the legs obtained by using it.

  In the massager according to the above embodiment, the leg air cells 75, 76, 77, 78 and the foot side air cells each have one air cell disposed on the left and right of the leg or foot, and a pair of air cells Not only this, but a plurality of air cells are arranged, for example, a plurality of air cells are arranged side by side or up and down with respect to the calf, and these are collectively expanded and contracted. Alternatively, the leg or foot can be held by a plurality of pairs of air cells. When a plurality of air cells are provided as described above, the timing of expansion and contraction can be different depending on different pairs of air cells facing each other. For example, as leg air cells, the front air cells located beside the calf and the calf air back are located In the case where two sets of rear air cells are provided, the front air cells near the groove inlet side of the leg receiving portion are expanded first, and then the rear air cells are expanded to ensure holding of the legs. be able to.

  Moreover, in the massage machine according to the embodiment, while the position of the foot receiving portion 16 can be adjusted with respect to the base portion 15a by the actuator 16c, the foot receiving portion 16 is used as the base portion 15a when moving the leg receiving portion 15b. In addition to this, although it is not configured to move, in response to the situation where the necessity of adjusting the position of the foot support is scarce, etc., the foot support is integrally fixed to the base and the leg support 15b is moved. The foot support can be configured to be maintained as it is without moving the foot support relative to the base regardless of the state of the foot support, etc., and the structure related to the movement of the foot support can be omitted. Can be simplified and reduced in cost.

Second Embodiment of the Present Invention
In the massage machine according to the first embodiment, the leg receiving portion 15b of the leg support portion 15 is movable in the leg longitudinal direction with respect to the base portion 15a using the treatment actuator 18, and the leg receiving portion 15b Although the holding target portion (calf portion) of the held leg is moved with respect to the other portion of the leg and the leg together with the leg receiving portion 15b, a predetermined treatment effect accompanied by the movement is generated, but this is also shown in FIG. Thus, the leg receiving portion 15d is movable in the front-rear direction with respect to the base portion 15a, and the leg receiving portion 15d in a state of holding the leg is moved in the front-rear direction of the leg by the predetermined actuator 19a with respect to the base portion 15a. The foot is held so as not to move back and forth in the foot support section 16, and the holding target site of the leg is moved back and forth so as to move relative to the foot, and the treatment effect equivalent to the massage accompanying the movement for the muscle of the holding target site is It may be configured to time difference.

  In the case where the leg receiving portion is similarly moved in the front-rear direction with respect to the base portion, the main purpose is to push the leg forward in the leg receiving portion to impart forward movement to the muscle of the holding target portion If the backward movement of the holding target part is not forced by the leg receiving part but based on the natural restoring force of the leg, the leg holding by the leg air cell at the leg receiving part does not perform the leg holding You can also Furthermore, when the massage for pressing the leg by the leg air cell is not performed in the leg receiving portion, the arrangement of the leg air cell can be omitted, and the structure of the leg receiving portion can be simplified.

  Further, as shown in FIG. 10, the leg receiving portion 15e can be moved in the lateral direction with respect to the base portion 15a, and the leg receiving portion 15e in a state of holding the leg is moved in the lateral direction of the leg with respect to the base portion. The foot is held so as not to move from side to side on the foot support 16, and the holding target site of the leg is moved so as to swing the foot to the left and right. It can also be configured to

  Further, as shown in FIG. 11, the leg receiving portion 15f is disposed on the base portion 15a so as to be pivotable about an axis different from the tilting axis of the leg supporting portion 15 and holding the leg. The portion 15f is vertically rocked with respect to the base portion 15a by the rocking actuator 19b, while the foot is held by the foot receiving portion 16 so that the holding target portion of the leg is rocked relative to the foot and held It may be configured to produce a treatment effect equivalent to a massage accompanying movement to the muscle of the target site. In addition, as a mechanism for swinging a leg receiving part, it can also be set as the mechanism which produces the rocking movement of a leg receiving part combining a link mechanism with a simple linear motion type actuator.

Furthermore, as another swing, as shown in FIG. 12, the leg receiving portion 15g can be pivoted to the left and right with respect to the base portion 15a, and the leg receiving portion 15g in a state of holding the leg is pivoted to the left and right with respect to the base portion. While moving the foot, the foot is held stationary against the foot support 16 and the holding target site of the leg is moved so as to swing relative to the foot. It may be configured to produce a treatment effect.
Besides this, as long as the leg receiving portion can be moved relative to the base portion without difficulty, a structure for moving the leg receiving portion may be suitably adopted so that the holding target portion of the leg can be moved relative to the foot. .

  Further, in the massager according to the first embodiment, the leg receiving portion 15b of the leg supporting portion 15 is provided with two groove portions 15c so as to be able to hold the left and right legs respectively, and moves relative to the base portion 15a. Although the holding target sites of the left and right legs are moved together as one, and the treatment effect accompanying the same movement is produced in the holding target sites of any of the legs, as shown in FIG. The leg receiving portions 15h and 15i can be configured to be independent left and right corresponding to the left and right legs respectively, and can be configured to be movable independently for the left and right leg receiving portions 15h and 15i with respect to the base portion 15a Even when the same holding target site is held by the legs of the left and right leg receiving portions 15h and 15i, different moving states are produced to produce different treatment effects for each of the left and right holding target sites, and fatigue state is caused by the left and right legs. Etc are different You can perform an appropriate treatment in response to each leg when that. Further, position adjustment of the leg receiving portion with respect to the base portion 15a to determine the holding target portion of the leg is performed for each of the left and right leg receiving portions 15h and 15i, and the holding target portion is made different for the left and right legs. In this case as well, the left and right leg receiving portions 15h and 15i can be moved to generate different treatment effects for each of the left and right holding target portions.

  In addition to these, as shown in FIG. 14, when moving the leg receiving portions 15j and 15k, which are configured to be movable independently to the left and right, in the leg longitudinal direction, respectively, It can be configured to be able to perform massage by twisting and squeezing the holding target site of the leg so as to rotate and also give a twisting movement to the holding target site of each of the left and right legs. It can give a massage effect.

  In the massager according to the first embodiment, the foot support 16 as the foot holding means restrains the movement of the foot toward the seat 12 with the foot air cells 79a, 79b, 79c, 79d. In addition, the movement in the direction away from the seat portion 12 of the foot is restrained by the groove bottom surface of the foot receiving groove 16b in contact with the sole to hold the foot without causing the longitudinal movement of the foot. If you do not adopt a foot air cell massage to the foot, but you want to restrain the foot from moving similarly when the foot support 15b is moved by restraining the foot, as shown in FIG. The restraint of the foot in the portion 16 may be configured to be provided with restricting portions 16d and 16e that allow the foot to be inserted and removed from the rear while restraining movement toward the seat side of the foot by surrounding the instep. Needs to be operated like an air cell It can be the phrase of a very simple configuration. In this case, it is possible to provide a regulation portion shaped like an upper cover of sandals or slippers for each of the left and right legs.

  Furthermore, in the foot support portion 16 in contact with the sole, a sole air cell that provides expansion and contraction in contact with the sole and gives a predetermined massage effect to the sole, and a heater that gives warmth to the sole are provided. In addition to the movement of the leg support, it is possible to give an appropriate stimulus to enhance the relaxation effect.

Third Embodiment of the Present Invention
A massage machine according to a third embodiment of the present invention will be described based on FIG.
Similar to the first embodiment, the massager according to the present embodiment includes a chair-like component, an actuator for tilting these components, various treatment mechanisms, and a control unit 40 for controlling the operation of these components. On the other hand, the difference is that the control unit 40 inflates the leg air cell in the leg receiving portion 15b of the leg support portion 15 to hold the leg, and holds the leg on the leg receiving portion 15b. Prior to this, the leg receiving portion 15b is moved relative to the base portion 15a to adjust its position, and the leg receiving portion 15b accurately holds a portion identified as a holding target portion of the leg in advance.

  In addition, about control other than control concerning movement for position adjustment of this leg receiving part, and a structure of a massage machine, it is the same as that of the case of the said 1st Embodiment, and detailed description is abbreviate | omitted.

  As in the first embodiment, the control unit 40 first operates the foot side air cells 79a, 79b, 79c, and 79c of the foot support 16 in an operation process for treatment for moving the holding target site of the leg relative to the foot. 79d is inflated, and the instep part of the foot is pinched and held from the left and right of the left and right legs.

  After the expansion of the foot side air cells 79a, 79b, 79c, 79d of the foot receiving portion 16, the control portion 40 performs the air supply to the leg air cells 75, 76, 77, 78 of the leg receiving portion 15b. Then, each air cell is expanded to maintain the holding target portion of the leg. However, the holding target site of the leg, for example, the calf portion differs in position on the leg receiving portion depending on the user's physical constitution (leg length), and depending on the initial position of the leg receiving portion 15b The portion to be held may be displaced from the portion to be held of the leg.

  For this reason, the control unit 40 adjusts the position of the leg receiving portion 15b before inflating the leg air cell to execute holding of the leg. In detail, the control unit 40 sets the position of the leg holding target site, for example, the position of the calf, which is set based on the detection information acquired by the user's physical shape detection immediately after sitting on the massage machine, etc. The treatment actuator 18 is operated to move the leg receiving portion 15b relative to the base portion 15a to adjust the position so that the positions of the air cells for the legs of the leg receiving portion correspond to each other. As a result, it is possible to correctly hold and securely hold the holding target portion of the leg by the air cells for the legs of the leg receiving portion 15b.

  Subsequent to this position adjustment, the control unit 40 inflates the leg air cell, and the leg air cell holds the leg holding target portion with the leg receiving portion 15b, and then moves the leg receiving portion 15b to move the leg The holding target site is moved integrally with the leg receiving portion 15b to produce a predetermined treatment effect. However, the operation process of each part after holding the holding target portion of the leg in the leg receiving portion 15b is the same as that of the first embodiment, and the detailed description will be omitted.

  The control unit 40 completes the movement of the leg receiving portion 15b before the completion of the movement as position adjustment of the leg receiving portion 15b by the operation of the treatment actuator 18 when holding the holding target site of the leg to the leg receiving portion 15b. After stopping, at a predetermined timing until a predetermined time elapses, an operation relating to the holding of the leg receiving portion 15b, specifically, expansion of the air cells for legs is started (see FIG. 16).

  With regard to position adjustment of the leg receiving portion 15b, in a state in which the leg holding portion is properly held by the leg air cell, when the leg receiving portion 15b is moved, the leg holding target portion is also moved integrally, and the leg receiving portion Since position adjustment with respect to the leg can not be performed, naturally, it is necessary to finish the position adjustment of the leg receiving portion 15b before the holding target portion of the leg is surely held by the leg air cell.

  However, when the position adjustment of the leg receiving portion 15b is completed, it is desirable that the holding target portion of the leg be immediately held in the leg receiving portion in order to reduce the waiting time until the start of the treatment.

  In relation to holding of the holding target portion of the leg, the leg is moved relative to the leg air cell, that is, from the non-holding state where the leg air cell is moved with respect to the leg with respect to the leg to the positive holding state. Since it takes a predetermined time to expand the air cell, the control unit 40 sets the timing to start the expansion of the leg air cell in consideration of that time.

  For example, when it takes time for the leg air cell to expand to a state where it can properly hold the holding target portion of the leg, the control unit 40 stops at the end of the position adjustment of the leg receiving portion 15b, that is, movement completion. The expansion of the leg air cell is started without waiting for the legs (see FIG. 16; timing a), the position adjustment of the leg receiving portion 15b is completed, and the leg air cell is the target for holding the legs without leaving time Make sure to reach an expanded state that ensures retention of the site.

  Further, when the leg air cell is promptly expanded from the start of expansion to the expanded state where the holding target site of the leg can be properly held, the control unit 40 completes the position adjustment of the leg receiving portion 15b, that is, movement stop and At the same time as the operation of the treatment actuator is stopped (see FIG. 16; timing b), or after a slight time has elapsed from the end of position adjustment (see FIG. 16; timing c), inflation of the leg air cell is started You do not mind doing so.

  In the massager according to the above-described embodiment, the control unit 40 is the holding target site of the leg set based on the detection information in the user's body shape detection before the holding of the leg by the leg receiving unit is performed. The position of the leg receiving portion 15b is moved relative to the base portion 15a so that the position of each leg air cell of the leg receiving portion 15b corresponds to the position of the control portion 40. For example, position adjustment may be performed in which the leg receiving portion 15b is moved so that the position of the leg air cell position of the leg receiving portion 15b corresponds to the position of the holding target portion of the leg set in advance by the program. If it is difficult to make a difference in treatment effects due to a shift in the holding position due to a physical difference among users, etc., position adjustment of the leg receiving portion 15b may be performed corresponding to the holding target site of the leg uniformly determined by the program. If you It is possible to execute holding of the holding target portion by the leg receiving portion 15b in a short time without any problem by simple control and to sufficiently produce the treatment effect when the leg receiving portion 15b is moved relative to the foot. Become.

Fourth Embodiment of the Invention
A massage machine according to a fourth embodiment of the present invention will be described based on FIGS. 17 and 18.
As in the first embodiment, the massage machine according to the present embodiment in each of the drawings shows the respective sections in the form of a chair, the actuators for tilting them, various treatment mechanisms, and the control unit for controlling the operations thereof. The difference is that the control unit 40 inflates the leg air cell of the leg support portion 15 to hold the leg and move the leg receiving portion 15b relative to the base portion 15a. The foot receiving portion 16 is also configured to be moved relative to the base portion 15a in the direction opposite to the moving direction of the leg receiving portion.
The control other than the control related to the movement of the foot support in the direction opposite to the movement direction of the leg support and the configuration of the massage machine are the same as in the first embodiment, and the detailed description will be given. I omit it.

  In the first embodiment, while the leg receiving portion 15b is moved relative to the base portion 15a, the foot receiving portion 16 is not moved relative to the base portion 15b, whereas in the present embodiment, the foot receiving portion 16 is not moved. By moving the foot receiving portion 16 with respect to the base portion 15a by the actuator 16c, the foot is actually moved in the opposite direction to the moving direction of the leg receiving portion 15b.

  The foot support portion 16 is configured to be moved relative to the base portion 15a by the actuator 16c as in the first embodiment, and the leg length of the foot support portion 16 relative to the base portion 15a corresponds to the length of the user's leg. While the position can be adjusted in the direction, when the control unit 40 moves the leg receiving portion 15b of the leg support portion 15 relative to the base portion 15a, the moving direction of the leg receiving portion 15b is operated by the operation of the actuator 16c. Is a mechanism to move in the opposite direction.

  The control unit 40 controls the treatment actuator 18 of the leg support unit 15 to move the leg receiving unit 15 b of the leg support unit 15 with respect to the base unit 15 a. In accordance with the movement of the leg receiving portion 15b by the operation of the treatment actuator 18, the control portion 40 operates the actuator 16c and executes control to move the foot receiving portion 16 in the direction opposite to the moving direction of the leg receiving portion 15b. It will be done.

  The control unit 40 moves the foot support 16 and the foot held thereby in the direction opposite to the moving direction of the holding target portion of the leg support 15b and the leg held thereby, thereby the leg support The relative movement amount of the holding target site of the leg held at 15b with respect to the foot can be increased, and the strength of the treatment corresponding to the massage generated in the muscle etc. at the moving holding target site can be enhanced.

  Next, in the massager according to the present embodiment, the operation process of each part for treatment for moving the holding target site of the leg relative to the foot will be described. As a premise, in the same manner as the first embodiment, the user sitting on the massage machine 1 operates the massage machine 1 that has already been started and has completed preparation, adjustment, and the like before starting the massage. It is assumed that the control unit 40 tries to execute operation control related to treatment based on the movement of the leg receiving unit while being input and performing various massages.

  First, in the case where the leg receiving portion 15b of the leg support portion 15 moves from a position close to the seat portion to a side approaching the foot, and moves the calf portion as the holding target portion of the leg held by the leg receiving portion 15b. The operation process will be described.

  Here, the control unit 40 operates the tilting actuator 17 in advance to tilt the leg supporting portion 15 supporting the leg of the user, and the leg supporting portion 15 is at the initial position, that is, the holding target portion of the leg. Is brought to a predetermined inclination angle position of the leg support 15 suitable for treatment to move relative to the foot. Further, it is assumed that the leg receiving portion 15b of the leg supporting portion 15 is moved and adjusted so as to be closest to the seat portion 12. Then, when the user causes the leg supporting portion 15 to support the leg on the leg supporting portion 16 and places the foot on the leg receiving portion 16, the foot receiving portion 16 receives position adjustment corresponding to the length of the leg. The bottom of the foot receiving groove 16b is in contact with the sole.

  The control unit 40 first inflates the foot side air cells 79a, 79b, 79c, 79d of the foot support 16 to start the operation of each mechanical portion of the leg support 15, and the left and right legs of the foot Hold the instep part from the left and right and restrain appropriately.

  When the foot side air cells 79a, 79b, 79c, 79d are fully inflated and the foot is properly held, the user attaches the sole to the bottom of the foot receiving groove 16b of the foot receiving portion 16. The foot is held and restrained by the foot support 16.

  Then, the control unit 40 controls the air cells 75 for the legs located on both sides of the legs at the leg support 15 simultaneously with or slightly after the expansion of the foot side air cells 79a, 79b, 79c, 79d of the foot support 16. Supply air to 76, 77, 78 to expand each air cell. With the expansion of the leg air cells 75, 76, 77, 78, the calf portion as the holding target portion of the leg is held from both sides by the air cell and is held and restrained by the leg receiving portion 15b.

  When another air cell for holding the thigh of the leg is disposed on both sides of the seat 12, the control unit 40 inflates the leg air cells 75, 76, 77, 78, and then the thigh Air is supplied to the air cell 79 for a part, and this is inflated to perform pinching of the thigh (see FIG. 3).

  With the leg air cell fully expanded and the calf portion held and restrained, the control unit 40 operates the treatment actuator 18 of the leg support portion 15 to base the leg receiving portion 15b of the leg support portion 15 The portion 15a is moved little by little to the toe side which is the side away from the seat portion 12 (see FIG. 17).

  The movement of the leg receiving portion 15b by the treatment actuator 18 is started, and the control portion 40 operates the actuator 16c to move the foot receiving portion 16 toward the base portion 15a toward the seat portion, that is, the leg receiving portion 15b. Move in the opposite direction to the moving direction of.

  By moving the leg receiving portion 15b away from the seat portion 12 with respect to the base portion 15a by the treatment actuator 18, the calf portion held by the leg receiving portion 15b is also moved, and the portion below the leg and the leg Also in the same manner as the leg receiving portion 15b, a force is applied to move it away from the seat.

  Here, since the foot abuts on the bottom of the groove of the foot receiving groove 16b in the foot receiving portion 16 and the foot is restrained from moving beyond the foot receiving portion 16, the direction away from the seat portion The foot is not moved in the direction of the force with respect to the force of the foot, and the foot is moved to the side where the foot receiving portion 16 approaches the seat portion 12 with respect to the base portion 15a. At the same time, it moves so as to approach the seat 12 (see FIG. 17).

  The movement of the leg receiving portion 15b moves the muscle of the calf of the leg held by the leg receiving portion 15b away from the seat and in the direction toward the foot, while the moving leg receiving portion 15b and the muscle of the calf On the other hand, since the foot held by the foot support 16 moves in the opposite direction to the leg support 15b, the relative movement of the calf portion held by the leg support 15b in the direction approaching the foot increases. The movement of muscles in the calf can be promoted more than in the case where only the leg receiving portion 15b is moved. Thus, the muscles of the calf can be moved efficiently, and the effects of treatment as if a person had exercised muscles could be locally concentrated on the calf and given.

  Thereafter, the leg receiving portion 15b approaches its movement limit position as the movement toward the tip end of the leg proceeds. In addition, the foot support 16 also approaches its movement limit position as the movement toward the seat 12 progresses. The control unit 40 determines whether or not any of the movement of the leg receiving portion 15b or the movement of the foot receiving portion 16 has reached the movement limit.

  When it is determined that the movement limit has been reached, the control unit 40 puts both the treatment actuator 18 and the actuator 16c in the operation stop state, and moves the leg receiving portion 15b and the leg receiving portion 16 respectively. Stop it.

  As a result, the leg is not subjected to an excessive load beyond the appropriate treatment intensity range in the movement of the holding target site of the leg set in advance. On the other hand, when the respective portions have not reached the movement limit, the movement of the leg receiving portion 15b by the treatment actuator 18 and the movement of the foot receiving portion 16 by the actuator 16c are continued.

  At the same time as stopping the treatment actuator 18 and the actuator 16c, the control unit 40 switches the electromagnetic valves of the air supply and discharge adjustment mechanism, contracts all the air cells in the expanded state by discharging air, and holds the legs etc. When releasing from the state and holding the thigh with another air cell 79, the legs and feet will be released from restraint and return freely when this is released from the holding state by air discharge. .

  However, even after stopping the treatment actuator 18 and the actuator 16c, the control unit 40 continues the expansion state of each air cell for a while with the electromagnetic valve of the air supply / discharge adjustment mechanism as it is for a predetermined time. A state in which a force directed to the tip of the foot is applied to the calf muscle held by may be maintained for a predetermined time.

  And when the control part 40 performs the treatment concerning the movement of the said series of calf as one process of an automatic massage course, it transfers to the following massage and it is not an automatic course but is performed as an independent single treatment End the series of operation processes. However, if necessary, after releasing the foot or leg from the pinched state, the control unit 40 operates the treatment actuator 18 in the reverse direction to move the leg receiving portion 15b toward the seat portion 12, and The actuator 16c is operated reversely to move the foot support 16 away from the seat, and finally, the leg support 15b and the foot support 16 are returned to their pre-treatment positions, Deactivate each actuator again.

  Subsequently, the operation process in the case where the leg receiving portion 15b of the leg supporting portion 15 moves from the position closer to the foot to the side approaching the seat portion to move the muscle of the calf of the leg held by the leg receiving portion 15b explain.

  The control unit 40 operates the tilting actuator 17 as needed to tilt the leg support 15 supporting the user's leg, and the leg support 15 is at the initial position, that is, the holding target site of the leg. Is brought to a predetermined tilt angle position of the leg support 15 suitable for treatment to move relative to the foot. The foot receiving portion 16 is previously adjusted in position corresponding to the length of the leg, and the bottom surface of the foot receiving groove 16b in the foot receiving portion 16 is in a state of being in contact with the sole.

  The control unit 40 first inflates the foot side air cells 79a, 79b, 79c, 79d of the foot support portion 16 to start the operation of each mechanism portion of the leg support portion 15, and the foot among the left and right legs Hold the instep part from the left and right and restrain appropriately.

  Then, the control unit 40 controls the air cells 75 for the legs located on both sides of the legs at the leg support 15 simultaneously with or slightly after the expansion of the foot side air cells 79a, 79b, 79c, 79d of the foot support 16. Supply air to 76, 77, 78 to expand each air cell. With the expansion of the leg air cells 75, 76, 77, 78, the calf portion of the leg is sandwiched by the air cells from both sides, and is held and restrained by the leg receiving portion 15b.

  When another air cell for holding the thigh of the leg is disposed on both sides of the seat 12, the control unit 40 inflates the leg air cells 75, 76, 77, 78, and then the thigh Air is supplied to the air cell 79 for a part, and this is inflated to perform pinching of the thigh (see FIG. 3).

  With the leg air cell fully expanded and the calf portion held and restrained, the control unit 40 operates the treatment actuator 18 of the leg support portion 15 to base the leg receiving portion 15b of the leg support portion 15 The part 15a is moved away from the foot and gradually toward the seat 12 (see FIG. 18).

  While starting the movement of the leg receiving portion 15b by the treatment actuator 18, the control portion 40 causes the control portion 40 to operate the actuator 16c to move the foot receiving portion 16 away from the base portion 15a from the seat portion, That is, the leg receiving portion 15b is moved in the opposite direction to the moving direction.

  By moving the leg receiving portion 15b to the side closer to the seat portion 12 with respect to the base portion 15a by the treatment actuator 18, the calf portion held by the leg receiving portion 15b is also moved, and the portion below the leg and the foot Also in the same manner as the leg receiving portion 15b, a force is applied to move it in the direction approaching the seat portion.

  Here, the foot is held between the foot side air cells 79a, 79b, 79c, 79d in the foot support portion 16, and the foot does not move in the direction of separating the foot sole from the bottom of the foot receiving groove 16b. Because the foot is constrained, the foot is not moved in the direction of force toward the seat, and the foot support 16 is moved away from the seat 12 with respect to the base 15a. As a result, the foot moves integrally with the foot support 16 away from the seat 12 (see FIG. 18). Further, when the thigh air cell 79 is inflated to hold the thigh, even if a force is applied to the leg along with the movement of the leg receiving portion 15b, the thigh is held and restrained and does not move Thus, the entire leg does not move relative to the seat 12 as the leg receiving portion 15b moves, and the movement of the leg held by the leg receiving portion 15b is limited to only the holding target portion of the leg, The treatment effect by relative movement of this part relative to the other part of the leg can be reliably produced.

  By the movement of the leg receiving portion 15b, the muscles of the calf portion of the leg held by the leg receiving portion 15b are moved toward the seat portion, while the muscles of the moving leg receiving portion 15b and the calf portion Since the foot held by the receiving portion 16 moves in the opposite direction to the leg receiving portion 15b, the amount of relative movement of the calf portion held by the leg receiving portion 15b in the direction away from the foot increases. As compared with the case of moving only the portion 15b, it is possible to promote relative movement in the direction in which the calf portion and the foot move away from each other. Thus, the site between the calf and the foot can be efficiently stretched to give the effect as if stretching was performed.

  Furthermore, the thighs of the legs held by the thigh air cell 79 are at rest against the muscles of the moving leg receiving portion 15b and the calf, and relative movement of the leg receiving portion 15b is allowed relative thereto. Only the muscles of the calf portion held by the leg receiving portion 15b can be locally moved in a direction approaching the upper portion of the held stationary leg. In this way, the muscles in the calf can be moved to give the effect as if a person massaged moving muscles.

  Thereafter, the leg receiving portion 15b approaches its movement limit position as the movement toward the seat portion progresses. In addition, the foot support 16 also approaches its movement limit position as the movement away from the seat 12 progresses. The control unit 40 determines whether or not any of the movement of the leg receiving portion 15b or the movement of the foot receiving portion 16 has reached the movement limit.

  Then, when it is determined that the movement limit has been reached, the control unit 40 causes both the treatment actuator 18 and the actuator 16c to be in the operation stop state, and the movement of the leg receiving portion 15b and the movement of the foot receiving portion 16 Stop each one.

  As a result, the leg is not subjected to an excessive load beyond the appropriate treatment intensity range in the movement of the holding target site of the leg set in advance. On the other hand, when the respective portions have not reached the movement limit, the movement of the leg receiving portion 15b by the treatment actuator 18 and the movement of the foot receiving portion 16 by the actuator 16c are continued.

  At the same time as stopping the treatment actuator 18 and the actuator 16c, the control unit 40 switches the electromagnetic valves of the air supply and discharge adjustment mechanism, contracts all the air cells in the expanded state by discharging air, and holds the legs etc. When releasing from the state and holding the thigh with another air cell 79, the legs and feet will be released from restraint and return freely when this is released from the holding state by air discharge. .

  However, even after stopping the treatment actuator 18 and the actuator 16c, the control unit 40 continues the expansion state of each air cell for a while with the electromagnetic valve of the air supply / discharge adjustment mechanism as it is for a predetermined time. A state in which a force directed to the seat side is applied to the calf muscle held in the above may be further maintained for a predetermined time.

  And when the control part 40 performs the treatment concerning the movement of the said series of calf as one process of an automatic massage course, it transfers to the following massage and it is not an automatic course but is performed as an independent single treatment End the series of operation processes. However, if necessary, the control unit 40 operates the treatment actuator 18 in the reverse direction to move the leg receiving portion 15b away from the seat portion after releasing the foot or the leg from the pinched state, and The actuator 16c is operated reversely to move the foot support 16 toward the seat, and finally the leg support 15b and the foot support 16 are returned to their pre-treatment positions. Deactivate the actuator again.

  In the massager according to the embodiment, the leg receiving portion 15b of the leg support portion 15 is moved in the longitudinal direction of the leg relative to the base portion 15a, and the holding target portion (calf portion) of the leg held by the leg receiving portion 15b. When moving the foot with the leg receiving portion 15b, the foot receiving portion 16 is moved in the reverse direction, and the leg held by this is moved in the opposite direction to the moving direction of the holding target part of the leg. For example, as shown in FIG. 19, an air cell 16f that expands and contracts at a position contacting the sole of the foot support portion 16 is provided as shown in FIG. When moving in the direction away from the seat, the control unit 40 may expand the air cell 16f in contact with the sole and press the sole with the air cell 16f to move the foot toward the seat. As in the previous embodiment, the legs By increasing the amount of relative movement lifting the target site with respect to muscle retention target site can produce larger treatment effect of massage corresponds with the movement.

  In the massager according to the embodiment, the leg receiving portion 15b of the leg supporting portion 15 is moved in the longitudinal direction of the leg relative to the base portion 15a, and the holding target portion (calf portion) of the leg held by the leg receiving portion 15b. When moving the foot with the leg receiving portion 15b, the foot receiving portion 16 is moved in the reverse direction, and the leg held by this is moved in the opposite direction to the moving direction of the holding target part of the leg. For example, as shown in FIG. 20, an air cell 12a is provided which is expanded and contracted at a location in contact with the sole of the foot (the back of the thigh) of the seat 12 as shown in FIG. When the leg receiving portion 15b is moved away from the seat portion 12, the control portion inflates the air cell 12a in contact with the back of the seat, and presses the thigh with this air cell 12a to seat the thigh Move to the upper part of the department and follow it By moving the foot, the foot can be moved in the direction opposite to the moving direction of the leg receiving portion 15b, and the relative moving amount of the holding target portion of the leg is increased as in the embodiment described above. It is possible to cause the treatment effect equivalent to the massage accompanying the movement to the muscle of the site to be produced more.

  In addition, although it does not move the foot, the air cell 12a of the seat 12 is inflated to generate an upward pressure and resist the force in the direction away from the seat 12 of the leg receiving portion 15b. It is possible to prevent the whole part below the knee from falling and keep the position of the foot. In this case, the seat air cell 12a for holding the position of the foot is at least a part of the foot holding means, and the foot receiving portion as the foot holding means, specifically, the foot's downward movement while in contact with the sole. It is also possible to adopt a configuration in which one having a part to be restrained is not provided.

  In the massager according to each of the first and fourth embodiments, when the leg is held by the leg receiving portion 15b, the entire foot sole is on the bottom of the foot receiving groove 16b of the foot receiving portion 16. It is in a natural posture, and in that relationship it is configured to be held by the leg receiving portion 15b in a natural state without any particular tension on the leg from the knee, but in addition to this, the part where the leg is held It is also possible to adopt a configuration in which the legs are held by the leg receiving portion 15b after changing the muscles of the above into a predetermined state. For example, it is possible to provide pushing means, such as air cells 16g and 16h, for pushing up the positions of the soles at locations where the soles contact the heel and toe positions of the soles, respectively.

  Among them, when the heel position is pushed up by the air cell 16g (see FIG. 21A), the muscle shape of each part of the leg is changed in a contracted and expanded state in the longitudinal direction of the leg, and the muscle in the calf is thickened and deformed. It can be held by the leg receiving portion after being allowed to move (see FIG. 21 (B)). Conversely, when the toe position is pushed up with the air cell 16h (see FIG. 22A), the muscle shape of each part of the sole is extended in the longitudinal direction of the leg and changed to a deflated state, and the muscle in the calf is thinly deformed It can be held by the leg receiving portion after being allowed to move (see FIG. 22 (B)). Thus, by changing the state in which the leg muscles are held by the leg air cells of the leg support portion, various massage effects can be obtained.

Fifth Embodiment of the Invention
A massage machine according to a fifth embodiment of the present invention will be described based on FIGS. 23 and 24. FIG.
As in the first embodiment, the massage machine according to the present embodiment in each of the drawings shows the respective sections in the form of a chair, the actuators for tilting them, various treatment mechanisms, and the control unit for controlling the operations thereof. Although the control unit 40 inflates the leg air cell of the leg receiving portion 15b of the leg supporting portion 15 to hold and hold the leg as a different point, the leg receiving portion 15b is a base portion. The foot support portion 16 is moved relative to the base portion 15a without being moved relative to 15a, and the holding target portion of the leg held by the leg reception portion 15b is another portion such as the foot held by the foot reception portion 16 It has a configuration to move relative to it.
The control other than the control relating to the movement of the foot receiving portion replacing the leg receiving portion and the configuration of the massage machine are the same as those of the first embodiment, and the detailed description will be omitted.

  In the first embodiment, the control unit 40 controls the leg receiving portion 15b to move relative to the base portion 15a, whereby the leg receiving portion 15b and the leg are held with respect to the foot held by the foot receiving portion 16. In contrast, in the present embodiment, the control unit 40 moves the leg receiving portion 15b relative to the base portion 15b instead of moving the holding target portion in the moving direction of the leg receiving portion 15b. The foot support 16 is moved relative to the base 15a by the actuator 16c to move the foot support 15b and the leg holding target relative to the foot in the direction opposite to the direction in which the foot moves. .

  Similar to the first embodiment, the leg receiving portion 15b is provided with leg air cells 75, 76, 77, 78 so as to be able to hold the holding target portion of the leg, but as a different point, a base portion It has the structure supported by a fixed state, without making it move with respect to 15a.

  The foot support portion 16 is configured to be moved relative to the base portion 15a by the actuator 16c as in the first embodiment, and the leg length of the foot support portion 16 relative to the base portion 15a corresponds to the length of the user's leg. The position can be adjusted in the direction, and the difference is that the actuator 16c moved by the control unit 40 is moved in a predetermined direction so that the leg receiving unit 15b is moved relative to the foot receiving unit 16 It is

  The control unit 40 operates the actuator 16c to control the foot support 16 to move relative to the base 15a. As a result, the foot receiving portion 16 and the foot held thereby, and the portion other than the holding target portion of the leg connected to the foot are not moved on the base portion 15 a It can be moved relative to the target site, which leads to relative movement of the holding target site of the leg held by the leg receiving portion 15b with respect to the other part of the foot or leg, thereby moving muscles etc. in the holding target site Thus, the effect of treatment equivalent to massaging or stretching can be produced in the muscle or the like of the portion to be held.

  Next, in the massager according to the present embodiment, the operation process of each part for treatment for moving the holding target site of the leg relative to the foot will be described. As a premise, in the same manner as the first embodiment, the user sitting on the massage machine 1 operates the massage machine 1 that has already been started and has completed preparation, adjustment, and the like before starting the massage. While being input and performing various massages, it is assumed that the control unit 40 is to perform operation control relating to treatment based on the relative movement of the leg receiving unit.

  First, while the leg receiving portion 15b of the leg support portion 15 is not moved relative to the base portion 15a, the foot receiving portion 16 is moved relative to the base portion 15a in a direction approaching the seat portion 12 and held by the leg receiving portion 15b. The working process in the case of moving the muscles of the calf of the leg relative to the foot will be described.

  Here, the control unit 40 operates the tilting actuator 17 in advance to tilt the leg supporting portion 15 supporting the leg of the user, and the leg supporting portion 15 is at the initial position, that is, the holding target portion of the leg. Is made to reach a predetermined tilt angle position of the leg support 15 suitable for treatment to move relative to the foot. The foot receiving portion 16 is previously adjusted in position corresponding to the length of the leg, and the groove bottom surface of the foot receiving groove 16 b in the foot receiving portion 16 is in a state of being in contact with the sole.

  The control unit 40 first inflates the foot side air cells 79a, 79b, 79c, 79d of the foot support portion 16 to start the operation of each mechanism portion of the leg support portion 15, and the foot among the left and right legs Hold the instep part from the left and right and restrain appropriately.

  Then, the control unit 40 controls the air cells 75 for the legs located on both sides of the legs at the leg support 15 simultaneously with or slightly after the expansion of the foot side air cells 79a, 79b, 79c, 79d of the foot support 16. Supply air to 76, 77, 78 to expand each air cell. With the expansion of the leg air cells 75, 76, 77, 78, the calf portion of the leg is sandwiched by the air cells from both sides, and is held and restrained by the leg receiving portion 15b.

  With the leg air cell fully expanded and the calf held in place and restrained, the control unit 40 operates the actuator 16c to move the foot support 16 toward the seat 12 relative to the base 15a. Let it go (see FIG. 23). At this time, the calf portion as a holding target portion of the leg restrained and held by the leg air cell in the leg receiving portion 15b which does not move with respect to the base portion 15a of the leg support portion 15 extends in the leg longitudinal direction with respect to the base portion 15a. It does not move.

  On the other hand, the foot receiving portion 16 moves to the side closer to the seat portion 12 with respect to the base portion 15a, and the foot abuts the sole of the foot receiving groove 16b in the foot receiving portion 16 Since the foot is constrained so as not to move beyond the foot support 16, the foot moves in a direction approaching the foot support 15b integrally with the foot support 16 (see FIG. 23). Then, most of the legs except the holding target portion of the leg that is held by the leg receiving portion 15b and does not move by movement of the foot receiving portion 16 move the foot receiving portion 16 due to the force applied from the foot to the leg as the foot receiving portion 16 moves. As a result, the seat portion 12 moves relative to the seat portion 12 to ensure relative movement relative to the other portion of the holding target portion.

  While the leg receiving portion 15b and the muscles of the calf portion of the leg held by the leg receiving portion 15b are maintained stationary with respect to the base portion 15a, the foot held by the foot receiving portion 16 is the leg receiving portion relative to the base portion 15a. The movement in the direction of approaching 15b and the like causes relative movement of the calf portion held by the leg receiving portion 15b in the direction of approaching the foot. In this way, the muscles of the calf move relative to the foot and move separately from the other parts of the foot or leg, and it is possible to locally impart to the calf the effect as if a person massaged the muscles. .

  Thereafter, the foot receiving portion 16 approaches its movement limit position as the movement toward the seat portion 12 progresses. The control unit 40 determines whether the movement of the foot support 16 has reached the movement limit. Then, when it is determined that the movement limit has been reached, the control unit 40 causes the actuator 16 c to be in the operation stop state, and stops the movement of the foot receiving unit 16.

  As a result, the leg is not subjected to an excessive load beyond the appropriate treatment intensity range in the movement of the holding target site of the leg set in advance. On the other hand, when the foot receiving part 16 has not reached the movement limit, the control part 40 continues the movement of the foot receiving part 16 by the actuator 16c.

  At the same time as stopping the actuator 16c, the control unit 40 switches the electromagnetic valves of the air supply and discharge adjustment mechanism to contract all the air cells in the expanded state by discharging the air to release the legs and the like from the holding state The legs and feet are unconstrained and return to free movement.

  However, even after stopping the actuator 16c, the control unit 40 maintains the pressure control state of the air supply / discharge adjustment mechanism as it is for a predetermined time, and keeps the expanded state of each air cell for a while, A state in which a force toward the seat side is applied to the muscle may be further maintained for a predetermined time.

  And when the control part 40 performs the treatment concerning the movement of the said series of calf as one process of an automatic massage course, it transfers to the following massage and it is not an automatic course but is performed as an independent single treatment End the series of operation processes. However, if necessary, the control unit 40 operates the actuator 16c in the reverse direction to move the foot support 16 away from the seat after releasing the foot or the leg from the pinched state, and finally, After the foot support 16 is returned to the position before the treatment, the actuator is put into the operation stop state again.

  Subsequently, while the leg receiving portion 15b of the leg supporting portion 15 is not moved with respect to the base portion 15a, the foot receiving portion 16 is moved with respect to the base portion 15a away from the seat portion 12 and held by the leg receiving portion 15b. The working process in the case of moving the muscles of the calf of the leg relative to the foot will be described.

  The control unit 40 operates the tilting actuator 17 as needed to tilt the leg support 15 supporting the user's leg, and the leg support 15 is at the initial position, that is, the holding target site of the leg. Is brought to a predetermined tilt angle position of the leg support 15 suitable for treatment to move relative to the foot. The foot receiving portion 16 is previously adjusted in position corresponding to the length of the leg, and the bottom surface of the foot receiving groove 16b in the foot receiving portion 16 is in a state of being in contact with the sole.

  The control unit 40 first inflates the foot side air cells 79a, 79b, 79c, 79d of the foot support 16 to start the operation of each mechanical portion of the leg support 15, and the left and right legs of the foot Hold the instep part from the left and right and restrain appropriately.

  When the foot side air cells 79a, 79b, 79c, 79d are fully inflated and the foot is properly held, the user attaches the sole to the bottom of the foot receiving groove 16b of the foot receiving portion 16. The foot is held and restrained by the foot support 16.

  Then, the control unit 40 controls the air cells 75 for the legs located on both sides of the legs at the leg support 15 simultaneously with or slightly after the expansion of the foot side air cells 79a, 79b, 79c, 79d of the foot support 16. Supply air to 76, 77, 78 to expand each air cell. With the expansion of the leg air cells 75, 76, 77, 78, the calf portion as the holding target portion of the leg is held from both sides by the air cell and is held and restrained by the leg receiving portion 15b.

  When another air cell for holding the thigh of the leg is disposed on both sides of the seat 12, the control unit 40 inflates the leg air cells 75, 76, 77, 78, and then the thigh Air is supplied to the air cell 79 for a part, and this is inflated to perform pinching of the thigh (see FIG. 3).

  When the leg air cell is fully expanded and the calf portion is held and restrained, the control unit 40 operates the actuator 16c to move the foot support 16 away from the seat 12 with respect to the base 15a. Let it go (see FIG. 24). At this time, the leg portion as a holding target portion of the leg which is restrained by the leg air cell and held by the leg receiving portion 15b which does not move with respect to the base portion 15a does not move in the leg longitudinal direction with respect to the base portion 15a.

  On the other hand, the foot receiving portion 16 is moved to the side away from the seat portion 12 with respect to the base portion 15a, and the foot is held by the foot side air cells 79a, 79b, 79c, 79d in the foot receiving portion 16 Is restrained so as not to move the foot sole in a direction away from the bottom surface of the foot receiving groove 16b with respect to the foot receiving portion 16, the foot moves integrally with the foot receiving portion 16 away from the seat portion 12. That is, the foot support 16 and the foot held thereby move in a direction away from the leg support 15b (see FIG. 24).

  While the leg receiving portion 15b and the muscles of the calf portion of the leg held by the leg receiving portion 15b are maintained stationary with respect to the base portion 15a, the foot held by the foot receiving portion 16 is the leg receiving portion relative to the base portion 15a. The movement away from 15b and the like causes relative movement of the calf portion held by the leg receiving portion 15b in the direction away from the foot. In this way, the muscles in the calf move relative to the foot and move separately from the other parts of the foot or leg, stretching the part between the calf and the foot in the leg, as if stretching were performed. It can give an effect.

  After this, the foot receiving portion 16 approaches its movement limit position as the movement away from the seat portion 12 progresses. The control unit 40 determines whether or not the movement of the foot support 16 has reached the movement limit. Then, when it is determined that the movement limit is reached, the control unit 40 stops the movement of the foot support 16 by setting the actuator 16 c in the operation stop state.

  As a result, excessive load is not applied to the leg beyond the appropriate treatment intensity range in relative movement of the holding target portion of the leg set in advance. On the other hand, when the foot receiving part 16 has not reached the movement limit, the control part 40 continues the movement of the foot receiving part 16 by the actuator 16c.

  At the same time as stopping the actuator 16c, the control unit 40 switches the electromagnetic valves of the air supply and discharge adjustment mechanism, causes all air cells in the expanded state to contract by discharging air, and releases the legs and the like from the pinched state. Further, when the thigh is held by another air cell 79, if the air is released from the held state also by the air discharge, the legs and feet return to a state where they are released from restraint and can be freely moved.

  However, even after stopping the actuator 16c, the control unit 40 maintains the pressure control state of the air supply / discharge adjustment mechanism as it is for a predetermined time, and keeps the expanded state of each air cell for a while, A state in which a force directed to the foot support side is applied to the muscle may be further maintained for a predetermined time.

  And when the control part 40 performs the treatment concerning the movement of the said series of calf as one process of an automatic massage course, it transfers to the following massage and it is not an automatic course but is performed as an independent single treatment End the series of operation processes. However, if necessary, the control unit 40 operates the actuator 16c in the reverse direction to move the foot support 16 toward the seat after the foot or the leg is released from the pinched state, and finally, After the foot support 16 is returned to the position before the treatment, the actuator is put into the operation stop state again.

Sixth Embodiment of the Invention
In each of the first, fourth, and fifth embodiments, the holding target portion of the leg held by the leg receiving portion 15b is moved relative to the other portion of the foot or leg by the movement of the leg receiving portion 15b, or The base portion 15a of the leg support portion 15 is configured not to move relative to the seat portion 12 when moving the foot relative to the foot by movement of the portion 16, but the present invention is not limited thereto. As shown in FIG. 25 to FIG. 28, with the leg receiving portion 15b holding the holding target portion of the leg, the tilting actuator 17 is operated to tilt the leg supporting portion 15 as a whole to seat the base portion 15a. A configuration to obtain a state in which the leg or other part of the leg is moved relative to the part to be held of the leg held by the leg receiving part 15b by moving relative to the part 12 based on the tilting of the entire leg supporting part, more preferably And the other part of the leg and the direction in which the leg holder moves Configuration in the direction opposite to the relative movement, and can be.

  For example, when moving the leg receiving portion 15b holding the calf portion as the holding target portion of the leg in a direction away from the seat portion with respect to the base portion 15a, the leg support portion 15 is tilted upward (FIG. 25) , See Figure 26).

  In this case, while the distance between the front of the base of the leg support 15 and the upper surface of the seat 12 decreases with the upward tilting of the leg support 15, the leg tries to maintain its length as a whole. An extra length with respect to the support portion 15 is generated, and the lower part of the leg than the knee tends to shift to the foot tip side with respect to the leg support portion 15. However, the foot abuts the sole of the foot on the groove bottom of the foot receiving groove 16b in the foot receiving portion 16, and the foot is restrained not to move beyond the foot receiving portion 16, and the foot receiving portion 16 Since it is integral with the portion 15 a and approaches the upper surface of the seat 12, the foot also approaches the upper surface of the seat 12 integrally with the foot receiving portion 16. Therefore, with the position change of the foot accompanying the upward tilting of the leg supporting portion 15, the lower portion of the leg whose length is to be maintained is the upper surface of the seat 12 with respect to the leg supporting portion 15 by the extra length. It will cause the movement to shift in the direction of approaching.

  At this time, the calf portion held by the leg receiving portion 15b is similarly moved by moving the leg receiving portion 15b away from the seat portion 12 and approaching the foot with respect to the base portion 15a by the treatment actuator 18. However, as the other part of the leg and the leg move toward the upper surface of the seat portion 12, the relative movement of the calf portion held by the leg receiving portion 15b in the direction approaching the foot increases. The movement of muscles in the calf can be promoted more than when moving only. In this way, it is possible to move the muscles of the calf more efficiently, and to concentrate the effects of treatment as if a person massaged the muscles, locally on the calf.

  Besides, contrary to the above, when the leg receiving portion 15b holding the calf portion of the leg is moved in the direction approaching the seat portion 12, the leg supporting portion 15 may be tilted downward (FIG. 27, See FIG. 28). In this case, while the distance between the front surface side of the base portion of the leg support 15 and the upper surface of the seat portion 12 increases as the leg support 15 tilts downward, the leg as a whole tries to maintain its length. The lower part of the leg than the knee tends to shift toward the seat with respect to the leg support 15. However, the foot is held between the foot side air cells in the foot receiving portion 16 so that the foot is restrained so as not to move away from the bottom of the foot receiving groove 16b with respect to the foot receiving portion 16; The foot receiving portion 16 is integral with the base portion 15a, and since the foot receiving portion 16 is separated from the upper surface of the seat portion 12, the foot is also separated from the upper surface of the seat portion 12 integrally with the foot receiving portion 16. Therefore, with the change in position of the foot accompanying the downward tilting of the leg support 15, the lower leg part of the leg moves away from the top of the seat 12 as a whole to follow the change in position of the foot.

  At this time, the calf portion held by the leg receiving portion 15b is similarly moved by moving the leg receiving portion 15b toward the seat portion 12 and moving away from the foot with respect to the base portion 15a by the treatment actuator 18. However, as the other part of the leg and the leg move away from the upper surface of the seat 12 in the direction opposite to the leg support 15b, the relative movement of the calf portion held by the leg support 15b in the direction away from the foot is It is possible to promote relative movement in the direction in which the calf portion and the foot move away from each other more than in the case where only the leg receiving portion 15b is moved. Thus, the site between the calf and the foot can be extended more efficiently to give the effect as if stretching was performed.

Seventh Embodiment of the Invention
In the massager according to each of the first to sixth embodiments, the leg receiving portion or the foot receiving portion 16 is configured to move the holding target portion of the leg held by the leg receiving portion relative to the foot or the other portion of the leg. When moving the leg support unit 15 or tilting the whole leg support unit 15, the actuators for moving the respective parts are operated only once in one direction, and the movements of the leg receiving unit, the foot receiving unit 16 and the leg supporting unit 15 are Although it is considered as one kind of simple movement such as movement to a predetermined direction or tilting, and it is configured to be performed only once, the invention is not limited thereto, for example, after operating the actuator in one direction and then reverse direction. The movement of the leg receiving portion, the leg receiving portion 16 and the leg supporting portion 15 is moved or tilted in a plurality of directions, the movement of the leg receiving portion or the leg receiving portion 16 or the leg The tilting of the support portion 15 is not only one but a plurality It may be configured to be executed repeatedly.

  For example, with regard to movement of the leg receiving portion, as shown in FIGS. 29 and 30, with the leg receiving portion 15b holding the holding target site of the leg, the treatment actuator 18 is reciprocated to operate the actuator in the forward direction. And the leg support 15b is moved away from the seat 12, and then the leg support 15b is moved toward the seat 12, corresponding to the reverse operation of the actuator, It is also possible to repeat a plurality of times, and to reciprocate the holding target portion of the leg held by the leg receiving portion 15b repeatedly with respect to the other part of the foot or the leg.

  In this case, while the leg receiving portion 15b is moving, the leg air cell is maintained in the expanded state, and the holding target site of the leg is held by the leg receiving portion 15b. It is made to operate in the opposite direction to the front (see FIG. 30). However, the holding of the holding target portion to the leg receiving portion and the operation of the actuator are not limited to the above, and as shown in FIG. 31, while repeatedly operating the actuator in each direction, the operating direction of the actuator The actuator is deactivated once when changing the position, and the air cell for the leg is also released from the expanded state once, and the movement of the leg receiving part is stopped and the predetermined period for releasing the holding target part of the leg is set. It may be

  In this configuration example, the control unit 40 temporarily suspends operation of the treatment actuator 18 having the leg receiving portion moved, and switches the solenoid valve of the air supply / discharge adjustment mechanism to air the leg air cell that has been in an expanded state. It is contracted by the discharge of and temporarily releases the holding target site of the leg from the holding state. At this time, even after the treatment actuator 18 is temporarily stopped, the control unit 40 keeps the electromagnetic valve of the air supply and discharge adjustment mechanism as it is for a predetermined time and maintains the pressure state of the air cells for the legs. Reference), hold the holding target site for a while, and maintain the state where the same force as the moving direction of the leg receiving section up to that point is applied to the muscle etc of the holding target section held by the leg receiving section It can also be done.

  After releasing the holding target site of the leg for a predetermined period, the control unit 40 again causes the leg air cell to be in the expanded state, the holding target site is held, and then the treatment actuator 18 is operated again. Will move the leg receiver in the reverse direction.

  In addition, while the treatment actuator 18 is reciprocated, while the leg receiving portion moves in the predetermined direction, the leg holding target portion is held, while the leg receiving portion moves in the opposite direction, the holding target portion is It is also possible to adopt a configuration in which a state in which the holding target portion is moved in one direction is intermittently repeated with an interval, without being held by the leg receiving portion and released. Specifically, as shown in FIG. 32 to FIG. 34, with the leg holding portion 15b holding the holding target site of the leg, the treatment actuator 18 is operated to make the leg support correspond to the positive direction operation of the actuator. After moving the part 15b away from the seat part 12 (see FIG. 32) and moving the holding target site of the leg held by the leg receiving part 15b with respect to the foot or other part of the leg, the treatment actuator 18 is activated once. At the same time as stopping, the inflated state of the leg air cell is released to temporarily release the holding target site of the leg from the holding state. The treatment actuator 18 is operated in the reverse direction to the previous position while the leg holding target portion is released, and the leg receiving portion 15b is returned to the initial position before the previous movement (see FIG. 33). When the leg receiving portion 15b is returned to the original position, the operation of the treatment actuator 18 is stopped, and after holding the holding target portion of the leg again, the treatment actuator 18 is operated to seat the leg receiving portion 15b. Move the object away from 12 to move the holding target part of the leg relative to the foot or other part of the leg, and repeat the same process thereafter (see FIG. 34), and the holding target part together with the leg receiving portion 15b After being moved only in the direction away from the seat 12, a treatment state is obtained in which a series of changes released and returned are repeated a plurality of times.

  In this example, when the leg receiving portion moves in the direction away from the seat portion in the movement direction of the leg receiving portion due to the operation of the treatment actuator 18, the holding target site of the leg is held in the leg receiving portion. Although the part is moved, conversely, as shown in FIG. 35, when the leg receiving part moves in the direction approaching the seat part in response to the reverse operation of the actuator, the holding target part of the leg By repeating the process of holding the leg support and releasing the leg when moving the leg support away from the seat, the holding target portion is moved only a few times toward the seat with the leg support. The configuration may be such that repeated treatment conditions can be obtained.
