JP 2003-310682 A Japanese Patent Laid-Open No. 10-248897

However, in the case of the above-mentioned Patent Document 2, it is a special example configured to treat the sole on the main surface of the leg support, and the leg support is generally provided to support the sole. When considering a chair-type massage machine, if the leg rest is in the front-up position, the knee may bend and the back of the leg may be lifted from the leg rest or seat as shown in FIG. In the case of a chair type massage machine having a massage function on the surface, it is the actual situation that a configuration having a leg raising function is not even assumed.
This invention makes it a subject to provide a novel massage with respect to a leg in the leg-raised state in view of such a situation.

A chair type massage machine according to the present invention is a chair body having a seat portion and a backrest portion that are arranged in a front-up state, a leg receiving portion that is movable up and down on the front side of the seat portion, A foot support portion that is extendable in the longitudinal direction of the leg on the distal end side, and can be moved until the support surface of the leg sole of the leg support portion is in a front-up state from a front-up state of the seat surface in the configuration the chair-type massage machine as on both sides of the seat portion provided with upper leg clamping means for clamping the thigh, thigh sandwich receive motion command to the front rising state of the leg receiving portion start the nipping operation of the unit, have a leg-raised mode leg receiving portions after clamping by said thigh clamping means is controlled such that the front rising state from front rising state of the seat surface, the feet in the leg raising mode The back support starts moving away from the soles and supports the back of the leg support Characterized but to complete the movement of the sole receiving portion before the front rising state from front rising state of the seat surface

As described above, according to the present invention, the user wearing the seat portion of the main body can be supported by the leg receiving portion at a position where the leg is higher than the seat surface, and each part can be easily removed from the leg. In addition to being able to massage, the leg support is in a state of being lifted forward from the seat surface with the force of pressing the thigh against the seat surface . The leg can be lifted upward while the force is applied, and the leg can be stretched while suppressing the bending of the knee.

  As described above, according to the present invention, if the operation of the invention according to claim 1 and the invention according to claim 2 can be obtained, and both the clamping means are controlled to be clamped at the same time, the legs can be lifted. The bending of the knee in the state can be further suppressed. In addition, as described above, the bending of the knee can be suppressed by sandwiching either the calf or the thigh. For example, when the calf is clamped by the calf clamping means, the thigh substantially corresponds to the position of the thigh clamping means. Therefore, the thigh pinching means can be used not only as a pinching action but also as a massage action by pinching / non-pinching. Conversely, when the thigh is clamped by the thigh clamp means, the calf clamp means can be used for massage.

  (4) The chair type massage machine according to the present invention is characterized in that movement control is performed to a state in which the backrest portion is raised in the leg raising mode as necessary.

  Thus, according to the present invention, the leg is lifted with the back raised as much as possible, and the stretch effect is improved.

  (5) The chair type massage machine according to the present invention is provided with a sole receiving portion that is extendable in the longitudinal direction of the leg on the distal end side of the leg receiving portion, if necessary. In the mode, the sole receiving part moves in a direction away from the sole.

  As described above, according to the present invention, there is an effect that the sole receiving part can be prevented from interfering with the movement of extending the leg necessary in the leg raising mode as much as possible.

  (6) The chair type massage machine according to the present invention is characterized in that either one or both of the calf pinching means and the thigh pinching means is constituted by an air cell and is held by supplying air to the air cell as necessary. And

  As described above, according to the present invention, the clamping means has a soft feel, and for example, the support surface on the back of the leg of the leg receiving portion may be moved until it is excessively raised from the front rising state of the seating surface. However, the pinching can be easily released or loosened, and excessive leg warping can be prevented.

  These outlines of the invention do not enumerate the features essential to the present invention, and a combination of these features can also be an invention.

The chair-type massage machine according to the present embodiment includes a chair body having a backrest portion and a seat portion, a leg placement portion that can be turned up and down on the front side of the seat portion, and at least the chair body or the leg placement portion. The leg mounting unit includes a leg receiving unit for receiving the leg and a plate-like foot support disposed on the lower end side of the leg receiving unit. Part.
The seat is mounted so that it rises slightly forward relative to the horizontal, and the support surface on the back of the leg of the leg receiving part is at least forwardly raised from the seat when the leg rest is pivoted upward. It is comprised so that.

The backrest portion can be reclined with respect to the seat portion. In the present embodiment, a mechanical massage unit including a kneading ball is arranged as a massage mechanism so as to be movable up and down and back and forth. Further, on both sides of the seat portion, a thigh-clamping air cell is disposed as a clamping means that can be inflated to clamp the thigh.
The leg mounting portion includes a foot receiving portion made of a substantially flat plate-like body, and a half-cylindrical left and right leg receiving portion having a substantially U shape in a cross-sectional view arranged above the foot receiving portion. The user can hold the legs centered on the calf portion on the left and right leg receiving portions, and can hold the lower limbs loosely by bringing the soles into contact with the sole receiving portions. Yes. The leg receiving portion is provided with a calf clamping air cell as a clamping means that can freely expand to clamp the calf.

 The leg mounting portion includes a foot receiving portion made of a substantially flat plate-like body, and a half-cylindrical left and right leg receiving portion having a substantially U shape in a cross-sectional view arranged above the foot receiving portion. The user can hold the legs centered on the calf portion on the left and right leg receiving portions, and can hold the lower limbs loosely by bringing the soles into contact with the sole receiving portions. Yes. The leg receiving portion is provided with a calf clamping air cell as a clamping means that can freely expand to clamp the calf.

  In the chair-type massage machine according to the embodiment, the footrest receiving portion is attached with a predetermined gap between the footrest receiving portion and the leg receiving portion, thereby forming a leg placing portion. The leg placing portion is configured such that the leg receiving portion and the foot receiving portion can be expanded and contracted in the longitudinal direction at a time. However, at least only the foot receiving portion may be extended and retracted.

  Air cells for air massage are provided on the backrest, seat, and leg mounting sections described above, respectively, and inflated and contracted by the air supply / exhaust mechanism in combination with the above-described thigh clamping air cell and calf clamping air cell. It is free. In addition, the thigh pinching air cell and calf pinching air cell have a function as a pinching means that suppresses unexpected movement of the leg as much as possible by using the pinching pressure in addition to the massage function by pinching. As the clamping means, means for moving the pressing piece mechanically other than those by the air cell supply / exhaust can be considered and not limited to the pneumatic system.

  In the chair type massage machine described above, in the present embodiment, the leg placement unit is rotated up and down, and a rotation position detection sensor for detecting a rotation position when the leg mounting unit is rotated up and down is provided. An extension position for detecting the position of the leg placement part from the front side of the seat part when the extension means is extended and contracted in the length direction of the leg of the user. An expansion / contraction means provided with a detection sensor and a control means for controlling operations of the rotation means and the expansion / contraction means are provided.

  Both the rotation means and the expansion / contraction means can preferably use an actuator such as an electric motor or a cylinder, and both the rotation position detection sensor and the expansion / contraction position detection sensor can use an optical sensor.

  With this configuration, in the chair type massage machine according to the present embodiment, it is possible to know the rotation position of the leg receiving portion of the leg placement portion and the stretched state of the foot receiving portion.

  This chair type massage machine controls the reclining function of the backrest part, the turning function of the leg receiving part, the holding function of the thigh clamping air cell and the calf clamping air cell, and the extension function of the sole receiving part by the control part. When a command is received at the discretion of the user or during an automatic course, each holding air cell is rotated so that one or both of the air cells are inflated so that the leg receiving portion is in a front-up state from the seating surface. Leg raising mode can be realized.

  This leg-lifting mode prevents the knee from bending when trying to lift the leg upward from the seat while sitting down, by pinching it with an air cell in advance, and the leg rest from the front-raised state of the seat. By enlarging the front-up state of the part, a motion that stretches the leg by applying a force that warps the leg and then lifts it upward is expected to achieve a leg stretching effect.

  In addition, in the leg raising mode, movement in the direction in which the backrest part rises or movement in the direction away from the sole of the foot receiving part may be added as necessary in addition to the above operation.

  First, when the backrest part is raised in the leg raising mode, the posture of the upper body is raised and the leg stretching effect is improved.

  In general, the angle between the seating surface and the backrest portion is about 90 degrees. However, the backrest portion may be controlled to rotate until it becomes a sharper angle in order to obtain further effects.

  In addition, if the sole receiving portion moves in a direction away from the sole in the leg raising mode, the possibility that the sole receiving portion interferes with the extension of the legs is reduced.

  The above configuration can be selectively adopted as necessary, and the effect of the present invention can be sufficiently expected if the knee bending state can be reduced by the above-described clamping even if the sole receiving portion does not move.

  If the foot support is not moved, the foot will act in the direction in which the pressing force increases with respect to the foot support in the leg-lifting mode. The function can work strongly and is convenient.

  The control means includes a control circuit in which a CPU, ROM, RAM, and the like are provided on a substrate, and is electrically connected to the actuator drive source. Further, this control means can control the drive of the entire chair-type massage machine including the control of the massage unit including the fir ball and other airbags including the leg airbag.

  Then, it is preferable that an operation means such as a remote controller (remote controller) is electrically connected to the control circuit as the control means so that a desired operation can be realized by an operation input by the user.

  Here, with reference to FIG. 4, the control part G which is a control means of the massage machine A which concerns on this embodiment is explained in full detail below.

  The control unit G is disposed in the base unit 2 and, as shown in the figure, a remote controller R (FIGS. 1 to 3), which is an operation means that can be remotely operated, is connected, and an operation provided on the remote controller R is provided. Control operations such as an automatic course programmed from the single function operation of the massage machine A, and the reclining operation of the backrest unit 3 and the leg rest 4 It is possible to control the up-and-down rotation operation and the expansion and contraction operation in the length direction of the legs. K is a display unit comprising a liquid crystal panel provided in the remote controller R.

  As illustrated, the control unit G includes a CPU, a memory unit G1 storing various massage programs and various control tables, the reclining motor m5, the leg mounting unit rotation motor m6, and the leg mounting unit telescopic motor m7. The drive control part G2 which performs drive control of the various motors including these, and interfaces G3 and G4 are provided.

  The CPU detects the reclining position by detecting the reclining angle of the remote control R and the backrest part 3 via the interface G3, and detects the vertical rotation angle of the leg rest part 4 to detect the reclining position.

  In addition, the CPU expands and contracts the leg placement unit rotation motor m6 as the rotation means of the leg placement unit 4 and the leg placement unit 4 in the length direction of the legs of the user via the interface G4. A leg placement unit telescopic motor m7 as an expansion / contraction means is connected to control the vertical rotation operation and the expansion / contraction operation of the leg placement unit 4.

  Further, the CPU moves the elevating motor m1, the kneading motor m3, the tapping motor m4, and the advancing / retreating motor for advancing / retreating the massage unit 11 through the interface G4. m2, and further, a reclining motor m5 which is a reclining means for performing a reclining operation of the backrest portion 3, an air bag air pump 25, and a heater H provided in the seat portion 1 are connected. This heater H makes it possible to massage comfortably even in winter.

  The CPU is connected to an air pump 25 via an interface G4. The air pump 25 can supply air to a plurality of air cells a1 to a9. The air cells a1 to a9 are expanded by opening / closing operations of electromagnetic valves (not shown). (Swelling) · The air cells a1 to a9 can be held in an expanded state (a swelled state) while being able to contract, and a comfortable air massage can be performed.

  With this configuration, on the basis of a command signal from the operation unit SO of the remote controller R, the control unit G has a plurality of automatic courses combined with various massage modes including a leg raising mode for the purpose of fatigue recovery, refresh, relaxation, etc. It is possible to perform basic massages such as Shiatsu, Fir (Rim Up / Lower), Striking, Rusting, Vibrate, Stretch, etc., as well as single manual massages of different types such as rolling, air massage, etc. And the back-and-forth rotation operation of the backrest part 3 can be performed.

  An operation button dedicated to the leg raising mode is provided in the operation unit SO, and when the operation button is operated, the following operation is executed.

First, by operating the leg raising mode button, the two thigh clamping air cells a6 and a6 arranged on both sides of the seat portion 1 are supplied with air and start to expand. After the expansion starts or substantially simultaneously, the leg rest 4 starts to rotate upward.
And before the rotation of the leg rest part 4 proceeds and rises forward from the seat surface Z, the thigh is clamped by the expansion of the thigh clamping air cell a6.
Therefore, the thigh-clamping air cells a6, a6 are pulled upward while the leg is stretched while the thigh is restrained from lifting from the seat surface, so that the leg is stretched upward. Stretch effect on hamstrings is obtained.
In this embodiment, since the rotation position of the leg rest 4 can be always detected by the rotation position detection sensor G6, the timing when it rises forward from the seat surface Z is checked. It can be satisfactorily controlled so as to be sufficiently held by the holding air cell a6.
Furthermore, if means for confirming the expansion state in the air cell (confirmation of presence / absence of exhaust or pressure detection in the air cell) is provided, the leg can be raised after being pinched more securely.
Although the above is a preferred embodiment, it is possible to execute the clamping before the front rising state is achieved by the control that accelerates the start of the expansion even if there is no means for detecting the rotation position or the expansion state.

In the above embodiment, the thigh clamping air cell a6 has been described as an example, but the calf clamping air cell a7 can perform the same operation.
When the calf is clamped, the calf clamping air cell a7 is trying to press the calf along the leg back support surface of the leg receiving portion 18, so that the leg tip is in a forwardly raised state, and bending of the knee can be suppressed. Therefore, the leg is pulled upward in a stretched state, and a stretch effect for so-called hamstrings on the back of the leg is obtained.
Of course, the thigh clamping air cell a6 and the calf clamping air cell a7 can be used simultaneously as clamping means.

In the leg raising mode, the operation of raising the backrest 3 can be linked as necessary.
When the backrest part 3 is raised, the user is forced to take a posture in which the upper body is raised, and the stretch effect in the leg raising mode is further improved. In the present embodiment, the angle between the seat portion 1 and the backrest portion 3 is about 90 degrees in the most narrowed state, but a configuration in which the angle is further reduced to an acute angle state may be adopted.

Next, it is also possible to control the sole receiving portion 17 to move in a direction away from the sole as necessary in the leg raising mode.
In this case, instead of moving immediately upon receiving the command of the leg raising mode, the rotation position of the leg rest portion 4 is confirmed, and it is determined that the foot support portion 17 can sufficiently extend without contacting the floor surface F. The movement has been started from the maximum, so that there is no risk of the soles coming into contact.
Although it is desirable to complete the movement before the leg receiving portion 18 is in the front rising state, if the movement is started at least before the leg receiving portion 18 is in the front rising state, there is a possibility that the sole will contact the sole receiving portion 17. It is reduced.

In addition, in the above description, the leg receiving portion is configured to be pivotally supported in front of the seat portion. However, it is not necessary to be attached to the seat portion. It may be a separate type premised on being performed.
Moreover, even if it is a bed type, if a backrest part and a seat part can be specified, in this invention, it can be regarded as a chair substantially.

  As mentioned above, although this invention was demonstrated through embodiment, only the specific example was illustrated in embodiment, and this invention is not specifically limited. Further, the effects described in the embodiments are merely a list of the most preferable effects resulting from the present invention, and the effects of the present invention are not limited to those described in the embodiments of the present invention.
