The directions in the description are appropriately shown in the drawings, and coincide with the front-rear direction, the left-right direction, and the up-down direction as viewed from a user who inserts the lower limb L into the lower limb massage machine 1 in a state of being seated on a chair or the like. In the following description, the "calf C" is also referred to as "1 st treatment portion", and the "leg T" is also referred to as "2 nd treatment portion".

Note that, regarding the massage position, for example, the position shown in fig. 7, that is, the massage position at which the 1 st massage member 13 is switched to the substantially horizontal direction so as to correspond to the calf C is referred to as "1 st position".

The position shown in fig. 8, that is, the massage position at which the 1 st massage member 13 is switched obliquely upward and forward so as to correspond to the upper portion of the calf C, the knee, and the like is referred to as "2 nd position".

The position shown in fig. 9, that is, the massage position at which the 1 st massage member 13 is shifted slightly rearward of the vertical so as to correspond to the leg T is referred to as "3 rd position".

The lower limb massage machine 1 of the present embodiment is configured to be capable of simultaneously performing: a massage in which the lower limbs L of the user who sits on the chair or the like and is placed on the floor R or the like are set as massage targets (treatment parts), and the feet F constituting the lower limbs L are rubbed and pressed with a pinching force; and massaging the calf C or the leg T by clamping. The lower limb massage machine 1 is configured to perform vibration and pressure massage such as finger pressure on the sole S.

The lower limb massage machine 1 of the present embodiment includes: an upper massage mechanism 11 for giving a massage action to either the calf C or the leg T of the user by the massage part; a lower massage mechanism 37 for giving a massage action to the feet F of the user; and a driving mechanism 23 for driving the upper massage mechanism 11 and the lower massage mechanism 37.

The upper massage mechanism 11 is built in the upper housing 2. The lower massage mechanism 37 is built in the lower case 8. The drive mechanism 23 is provided so as to be installed on the upper case 2 and the lower case 8.

That is, for example, in the "1 st position" shown in fig. 1, 7, etc., the left and right calf C can be fitted in the left and right 1 st treatment concave portions 7. In the "2 nd position" shown in fig. 8, the left and right calf C, knee, etc. can be inserted. In the "3 rd position" shown in fig. 5, 9, etc., the left and right legs T can be fitted.

The lower case 8 is formed in a dome shape (convex shape) with an upper surface rising upward in a curved shape. The lower housing 8 is provided with a space inside, and a lower massage mechanism 37, a driving mechanism 23 (both described in detail later) and the like are provided in the space. In the lower case 8, a mounting portion 32 to which the swing support portion 30 is mounted is provided.

The 2 nd treatment recess 9, which is opened upward and is insertable into the leg F of the user, is provided in parallel with the pair of right and left sides of the upper surface of the lower case 8. Further, although not shown, a lining material having elasticity and flexibility and having proper air permeability is provided in the pair of right and left 2 nd therapeutic recesses 9.

Further, the grip portions 10 are provided on both left and right sides of the lower case 8, and the lower limb massage machine 1 can be held and moved by putting the user's hand into the grip portions 10.

Here, the upper massage mechanism 11 stored in the upper casing 2 will be described.

As shown in fig. 1 to 9, the upper massage mechanism 11 of the present embodiment includes: a 1 st rotation shaft 12 provided to be directed in the left-right direction and rotated by a rotation driving force from an upper transmission shaft 27a constituting a driving mechanism 23 (described in detail later); a pair of left and right 1 st massage members 13 provided in the middle of the 1 st rotation shaft 12 and moved closer to and away from each other by the rotational driving force of the 1 st rotation shaft 12 to sandwich the upper treatment portion such as the calf C or the leg T; and a 1 st converting part 14 for converting the rotation driving force of the 1 st rotation shaft 12 into the approaching and separating motion of the pair of 1 st massaging members 13.

The upper massage mechanism 11 is provided on a base body 15 in a floating state above the lower casing 8, and is mounted to the upper casing 2 via the base body 15.

Shaft support portions 16 whose axes are oriented in the left-right direction are formed at both left and right end portions of the base body 15, and bearings (bearings) are fitted into the shaft support portions 16. The shaft support portion 16 rotatably supports both end portions of the 1 st rotation shaft 12 via bearings. The base body 15 is supported swingably by a swing support portion 30 (described in detail later).

The 1 st massaging member 13 is a member provided on the base body 15, and is provided in a pair so as to be laterally spaced apart from each other so as to sandwich the treatment portion such as the calf C or the leg T. The 1 st massaging member 13 gives a pinching (pressing) massaging action to the calf C or the leg T. The 1 st massage member 13 is formed as an elongated plate-like member, and is curved at a middle portion in the longitudinal direction.

In the "1 st position" shown in fig. 1, 7, etc., the 1 st massaging member 13 is in a state in which the distal end is bent downward, and a massaging action is given to the calf C (1 st treatment portion). In the "2 nd position" shown in fig. 8, the 1 st massaging member 13 imparts a massaging action to the calf C, the side portion of the knee, and the like in a state in which the tip is directed forward. In the "3 rd position" shown in fig. 5, 9, etc., the 1 st massaging member 13 gives a massaging action to the leg T (2 nd treatment portion) in a state in which the distal end is bent forward.

The 1 st rotation shaft 12 is disposed so that its axial center is oriented in the horizontal direction, and the base end side (1 st conversion portion 14) of the 1 st massage member 13 is disposed so as to extend through the horizontal direction. The 1 st rotation shaft 12 is supported by a 1 st gear case 28 and a pair of shaft support portions 16 constituting the drive mechanism 23.

The 1 st conversion unit 14 includes: a 1 st inclined protrusion 17 integrally rotated with the 1 st rotation shaft 12; a 1 st annular fitting portion 19 provided on the base end side of the 1 st massage member 13 and fitted to the 1 st inclined projecting portion 17 so as to be rotatable relative to the same; and a 1 st restriction portion 20 for restricting the 1 st massage member 13 from rotating along with the 1 st rotation shaft 12.

The 1 st inclined projection 17 has a cam surface 18 inclined to the 1 st rotation shaft 12 on the outer peripheral surface, and rotates obliquely with respect to the axial center of the 1 st rotation shaft 12. The 1 st inclined convex portion 17 (cam surface 18) is inclined in opposite directions between the pair of 1 st massage members 13. The 1 st massage member 13 performs a swinging motion by the tilting rotation of the 1 st tilting projection 17 externally fitted to the 1 st annular fitting portion 19.

The 1 st restriction portion 20 includes: a 1 st restricting pin 21 provided on the base end side of the 1 st annular fitting portion 19 and provided on the 1 st annular fitting portion 19; and a 1 st restricting groove 22 provided in the base body 15 and into which the 1 st restricting pin 21 is slidably fitted.

The 1 st restricting pin 21 protrudes from the 1 st annular fitting portion 19 in a direction opposite to the 1 st massaging member 13. The base 15 opposite to the 1 st restricting pin 21 is provided with a 1 st restricting groove 22 extending in the lateral direction. The 1 st restricting pin 21 is slidably inserted into the 1 st restricting groove 22, and the 1 st restricting pin 21 swings left and right in a substantially horizontal direction. Thereby, the 1 st annular fitting portion 19 and the 1 st inclined projecting portion 17 are restricted from rotating together.

Thus, the 1 st massage member 13 is provided in two groups so as to correspond to the 1 st treatment recess 7 on the left and right sides of the upper case 2. The pair of left and right 1 st massage members 13 perform a swinging motion for approaching and separating, thereby giving effective pinching massage to the calf C or the leg T.

The drive mechanism 23 is stored in the lower case 8, and rotates and drives the 1 st rotation shaft 12 of the upper massage mechanism 11 and the 2 nd rotation shaft 38 of the lower massage mechanism 37 (described in detail later) together, thereby operating the respective sandwiching massage mechanisms.

As shown in fig. 4, the driving mechanism 23 includes: a drive motor 24 that outputs a rotational drive force; a rotation driving force outputted from the driving motor 24 is inputted to the upper transmission shaft 27a of the upper massage mechanism 11; a lower transmission shaft 27b that inputs the rotational driving force output from the driving motor 24 to the lower massage mechanism 37; a 1 st gear box 28 transmitting the transmitted rotational driving force to the 1 st rotation shaft 12; and a 2 nd gear box 29 transmitting the transmitted rotational driving force to the 2 nd rotation shaft 38.

The upper massage mechanism 11 is driven by the rotational driving force transmitted by the upper transmission shaft 27a, and the lower massage mechanism 37 is driven by the rotational driving force transmitted by the lower transmission shaft 27 b.

The 1 st gear case 28 is supported by the swing support portion 30 and the upper end of the upper conveying shaft 27a is inserted. The 1 st rotation shaft 12 penetrates the 1 st gear case 28, and the 1 st rotation shaft 12 is disposed in the upper case 2 in the lateral direction. When the rotational driving force is input to the 1 st gear box 28 via the upper transmission shaft 27a, the 1 st rotation shaft 12 disposed to pass through rotates.

The 2 nd gear case 29 is provided between the 2 nd massage members 39a constituting the inner side of the lower massage mechanism 37 (described in detail later), and is inserted with the lower end of the lower conveying shaft 27 b. The 2 nd rotation shaft 38 penetrates the 2 nd gear case 29, and the 2 nd rotation shaft 38 is disposed in the lower case 8 in the lateral direction and constitutes the lower massage mechanism 37. When the rotational driving force is input to the 2 nd gear box 29 via the lower transmission shaft 27b, the 2 nd rotation shaft 38 disposed to pass through rotates. Further, predetermined worm teeth and worm gears are stored in the gear boxes 26, 28, 29.

As described above, the lower limb massage machine 1 of the present invention distributes the rotational driving force output from the driving motor 24 of the driving mechanism 23 to the upper transmission shaft 27a and the lower transmission shaft 27b, and inputs the rotational driving force to the upper massage mechanism 11 and the lower massage mechanism 37. That is, the lower limb massage machine 1 of the present invention drives the upper massage mechanism 11 and the lower massage mechanism 37 with one drive motor 24. In addition, a plurality of drive motors 24 may be provided, one drive motor may be used to drive the upper massage mechanism 11, and the other drive motor may be used to drive the lower massage mechanism 37.

As shown in fig. 1 to 9, the lower limb massage machine 1 of the present invention is configured such that the upper massage mechanism 11 is supported by the swing support portion 30 so as to swing around an axis in the left-right direction. The swing support portion 30 will be described in detail.

As shown in fig. 4, 6, and the like, the swing support portion 30 is provided at the upper portion of the lower case 8, and swingably supports the base end side (the center of the upper massage mechanism 11) of the upper case 2 so that the tip end side of the upper case 2 can be raised via a swing shaft 31 directed in the left-right direction. In the present embodiment, the swing shaft 31 is constituted by the same shaft body as the 1 st rotation shaft 12. That is, the center of the 1 st rotation shaft 12 in the longitudinal direction is the swinging shaft 31.

The swing support portion 30 is a support member erected upward from a placement portion 32 mounted in the upper center of the lower case 8, and is provided in one of the centers of the lower case 8. The swing support portion 30 extends upward from the mounting portion 32 in the lower case 8, and supports the 1 st gear case 28 constituting the drive mechanism 23 from below.

The mounting portion 32 is a mounting member provided at the upper center of the rear surface side in the lower case 8. The placement portion 32 is supported from below by the placement swing support portion 30. Further, an opening 33 is formed in the upper surface of the lower case 8 above the mounting portion 32. The swing support portion 30 attached to the mounting portion 32 is disposed so as to protrude upward through the opening portion 33 thereof. A cap 34 covering the swing support 30, the 1 st gear case 28, and the like is attached to the opening 33.

That is, the swing support portion 30 is provided in a protruding shape from an opening 33 provided in the upper portion of the lower case 8 via the mounting portion 32. The swing support portion 30 supports the 1 st gear case 28 from below, and supports the center of the 1 st rotation shaft 12 (swing shaft 31) in the longitudinal direction rotatably about the left-right axis through a bearing provided in the 1 st gear case 28. With this structure, the swing support portion 30 supports the upper massage mechanism 11 so as to be free to swing.

The upper massage mechanism 11 is supported by a single point of the swing support portion 30 provided at the upper center of the lower case 8, and is in a state of floating above the lower case 8.

In the present embodiment, when the upper housing 2 supported by the swing support portion 30 is tilted forward so as to be adjacent to the lower housing 8, the 1 st massage member 13 stored in the upper housing 2 is directed forward, and when the upper housing 2 is lifted up so as to be separated from the lower housing 8, the 1 st massage member 13 stored in the upper housing 2 is directed upward.

That is, in the present embodiment, the 1 st massaging member 13 can be switched from the "1 st position (position toward obliquely front lower side)" shown in fig. 7 to the "3 rd position (position toward upper side)" shown in fig. 9. That is, the 1 st massaging member 13 is switched between a plurality of stages of "1 st position (position in the substantially horizontal direction)" to "3 rd position (position slightly behind the plumb)" so as to be able to correspond to any one of the calf C (1 st treatment portion), the leg T (2 nd treatment portion), and the like.

The swing shaft 31 may be provided as a 2 nd shaft body different from the 1 st rotation shaft 12. In this case, the swing shaft 31 belonging to the 2 nd shaft is, for example, previously provided in the swing support portion 30 so that the shaft in the left-right direction is parallel to the axial center of the 1 st rotation shaft 12. The 1 st gear case 28 and the 1 st rotation shaft 12 may be rotatably supported by being provided around the left-right direction axis of the shaft body, and the upper massage mechanism 11 may be swingably supported.

Further, the swing support portion 30 may be configured to support the upper massage mechanism 11 so as to swing around an axis in the lateral direction, and may be configured other than the one illustrated in the present embodiment. The swing support portions 30 may be provided in a pair so as to protrude upward on both left and right sides of the upper portion of the lower case 8, for example. That is, the left and right ends of the 1 st rotation shaft 12 (the swing shaft 31) in the left and right direction are rotatably supported, and the left and right sides of the upper massage mechanism 11 are swingably supported via the 1 st rotation shaft 12.

The upper massage mechanism 11 of the present embodiment is provided with a width adjustment mechanism 35 capable of adjusting the width of the pair of 1 st massage members 13, since the shape (size) of the leg L is different from person to person even when the calf C and the leg T are large. The width adjustment mechanism 35 is provided on the 1 st massaging member 13a side on the outer side, and is configured by a screw portion 36 provided on the 1 st rotation shaft 12 and having external teeth forming a spiral shape, and an 1 st inclined projecting portion 17a on the outer side having internal teeth in threaded engagement with the screw portion 36. A button (not shown) for instructing the width adjustment mechanism 35 to adjust the width may be provided in the upper case 2.

When a user presses a button or the like provided in the upper case 2 or the like, the 1 st inclined protrusion 17a which is the outer side moves in the left-right direction on the screw portion 36, and the 1 st massage member 13a which is the outer side moves in the left-right direction. Thus, the width of the pair of 1 st massaging members 13 can be arbitrarily adjusted.

Since the shape (size) of the leg portion F varies from person to person, the width adjusting mechanism 35 may be provided in the lower massaging mechanism 37 described later.

It is preferable that a detection unit such as a distance sensor or a load sensor is provided in advance, and the detection unit detects the shape (size) of the lower limb L such as the calf C, the leg T, or the foot F of the user, and a configuration is provided in which the width adjustment mechanism 35 is linked to adjust the width of the pair of massage members based on the measurement result.

Although other mechanisms may be used as the width adjustment mechanism 35, the mechanism disclosed in japanese patent application laid-open No. 2017-153734, that is, the mechanism described above, is preferable.

The lower massage mechanism 37 of the present embodiment includes: the 2 nd rotation shaft 38 is provided so as to face in the left-right direction and is rotated by a rotational driving force from the lower transmission shaft 27b constituting the driving mechanism 23; a pair of left and right 2 nd massage members 39 provided at a middle portion of the 2 nd rotation shaft 38 and approaching and separating by a rotation driving force of the 2 nd rotation shaft 38 to sandwich a treatment portion including at least a foot portion F from a toe to a heel; and a 2 nd conversion unit 40 for converting the rotational driving force of the 2 nd rotation shaft 38 into the swinging motion of the pair of right and left 2 nd massage members 39.

The 2 nd massaging member 39 is provided at the bottom of the lower housing 8 above the 2 nd rotation shaft 38. The 2 nd massage member 39 is a plate-like member protruding in the front-rear direction, and is formed in a wrapped curved shape so as to wrap along the shape of the foot F such as the instep seed ankle seed heel. The 2 nd massaging member 39 is provided with a pair of left and right parts so as to sandwich the treatment portion of the foot F, and gives a sandwiching (pressing) massaging action to the foot F.

The 2 nd rotation shaft 38 is provided with its axis oriented in the horizontal direction, and is supported by 2 support members 47 provided at the bottom of the lower case 8 and the 2 nd gear case 29 of the drive mechanism 23 via bearings (bearings). The 2 nd rotation shaft 38 is provided so as to penetrate the base end side of the 2 nd massage member 39 (the 2 nd conversion portion 40) in the left-right direction.

The 2 nd conversion unit 40 includes: a 2 nd inclined protrusion 41 integrally rotated with the 2 nd rotation shaft 38; a 2 nd annular fitting portion 43 provided on the base end side of the 2 nd massage member 39 and fitted to the 2 nd inclined protruding portion 41 in a relatively rotatable state; and a 2 nd restricting portion 44 for restricting the rotation of the 2 nd massaging member 39 along with the 2 nd rotation shaft 38.

The 2 nd inclined projection 41 has a cam surface 42 inclined with respect to the 2 nd rotation shaft 38 on the outer peripheral surface, and rotates obliquely with respect to the axial center of the 2 nd rotation shaft 38. The 2 nd inclined projection 41 (cam surface 42) is inclined in opposite directions between the pair of 2 nd massage members 39. The 2 nd massage member 39 performs a swinging motion by the tilting rotation of the 2 nd tilting projection 41 externally fitted to the 2 nd annular fitting portion 43.

The 2 nd restriction portion 44 has: a 2 nd restriction pin 45 provided on the base end side of the 2 nd annular fitting portion 43 and provided on the 2 nd annular fitting portion 43; and a 2 nd restricting groove 46 provided in the lower case 8 and into which the 2 nd restricting pin 45 is slidably fitted.

The 2 nd restriction pin 45 protrudes from the 2 nd annular fitting portion 43 in a direction opposite to the 2 nd massage member 39. The lower case 8 opposite to the 2 nd restricting pin 45 is provided with a 2 nd restricting groove 46 long in the left-right direction. The 2 nd restricting pin 45 is slidably inserted into the 2 nd restricting groove 46, and the 2 nd restricting pin 45 swings left and right in a substantially horizontal direction. Thereby, the 2 nd annular fitting portion 43 and the 2 nd inclined projecting portion 41 are restricted from rotating together.

The lower massage mechanism 37 further includes a sole massage roller 48 for applying a pressing massage operation to the center (arch a) of the sole S in the longitudinal direction.

The sole massage roller 48 is provided at a position sandwiched by the pair of right and left 2 nd massage members 39. The sole massage roller 48 is a cylindrical member rotatably supported in the left-right direction with its axis center, and is penetratingly mounted on the 2 nd rotation shaft 38.

A plurality of treatment elements 49 are provided on the outer peripheral surface of the sole massage roller 48 at intervals in the circumferential direction and the axial direction of the 2 nd rotation shaft 38 and directed radially outward.

Thus, the 2 nd massage member 39 and the sole massage roller 48 are provided in a single group, and the two groups are provided so as to correspond to the 2 nd treatment recesses 9 on the left and right sides of the lower case 8.

By the swinging motion of the pair of right and left 2 nd massage members 39, effective pinching massage is applied to the foot F from the toe to the heel. The foot sole massage roller 48 rotates to apply the effective pressing massage to the arch a of the foot sole S by the treatment tool 49.

The lower limb massage machine 1 of the present embodiment is provided with a vibration massage mechanism 50. The vibration massage mechanism 50 has: a motor 51 generating a rotational driving force; a vibration generating unit (not shown) that converts rotational driving force into vibration; and a sole massaging member 52 that vibrates by the vibration generating portion.

The sole massaging member 52 is a rectangular frame, and the 2 nd rotation shaft 38 to which the sole massaging roller 48 is attached is provided in the frame. The sole massaging member 52 is provided with a plurality of protruding therapeutic elements 53 at positions corresponding to the front and rear sides of the sole S. The plurality of treatment members 53 are provided on the front side and the rear side so as to sandwich the sole massage roller 48 in the front-rear direction. At the lower part of the sole massage member 52, a vibrator 54 formed of an elastic body such as rubber is provided at least at four corners of the frame. The vibrator 54 is mounted at the bottom of the lower case 8.

The output shaft of the motor 51 is directed downward, and an eccentric cam (not shown) is attached to the front end thereof. The eccentric cam is fitted into a recess (not shown) provided in the sole massaging member 52. That is, the vibration generating portion has an eccentric cam attached to the output shaft of the motor 51 and a recess of the sole massaging member 52.

The sole massaging member 52 is vibrated by the vibration generated by the eccentric cam rotating in the recess while in contact with the cam. Further, since the vibrator 54 also vibrates simultaneously, the sole massaging member 52 is more vibrated. Thereby, the treatment tool 53 of the vibrating sole massage member 52 gives vibration massage to the front and rear sides of the sole S.

Here, the state of the 1 st massaging member 13 out of the "1 st position" to the "3 rd position" will be described with reference to fig. 7 to 9.

For example, in the "1 st position" shown in fig. 7, the 1 st massaging member 13 is provided so as to protrude forward in a substantially horizontal direction. The 1 st treatment concave portion 7 is opened upward and forward and downward. The cap 34 covering the swing support 30 is accommodated in the recess 6 formed in the lower cover 3.

The user inserts the calf C into the 1 st treatment recess 7 of the lower limb massage machine 1 and inserts the foot F into the 2 nd treatment recess 9.

The 1 st massaging member 13 applies a pressing massaging action to the calf C (1 st treatment portion) inserted into the 1 st treatment recess 7 so as to press the calf from the outside at the "1 st position". The upper massage mechanism 11 is fixed by sandwiching the calf C.

Specifically, as shown in fig. 7, the 1 st massaging member 13 covers the front portion of the calf C from the side, and the base end side covers the rear portion of the calf C from the side, so as to apply a pressing massaging operation to the entire calf C so as to press the calf C from the outside and the inside. Further, the position in the longitudinal direction of the 1 st massage member 13 is not the same depending on the size of the calf C of the user.

The 2 nd massaging member 39 applies a pressing massaging operation to the foot F (2 nd treating portion) inserted into the 2 nd treating recess 9 so as to press the foot F from the outside at the "1 st position".

In detail, as shown in fig. 7, the tip of the 2 nd massage member 39 is laterally covered with the toe, the heel is laterally covered with the rear end, and the foot F from the toe to the heel is pressed from the outside and the inside to give a pressing massage operation.

Here, when the user grips the side of the front end side of the upper casing 2 and lifts the upper massage mechanism 11 upward with a certain force about the axial center of the 1 st rotation shaft 12 (swing shaft 31), the upper massage mechanism can move toward the "2 nd position".

In the "2 nd position" shown in fig. 8, the 1 st massage member 13 is slightly raised upward and projects obliquely forward.

The 1 st massaging member 13 applies a pressing massaging action to the upper portion of the calf C inserted into the 1 st treatment concave portion 7 to the side below the knee so as to push the same from the outside at the "2 nd position". Further, the upper massage mechanism 11 is fixed by sandwiching the upper portion of the calf C under the knee.

Specifically, as shown in fig. 8, the 1 st massaging member 13 covers the upper portion of the calf C from the side to the vicinity below the knee in the longitudinal direction center portion, and applies a pressing massaging operation to the upper portion of the calf C so as to press the upper portion from the outside to the inside. In addition, the 2 nd position shown in fig. 8 can be said to show a transition from the 1 st position to the 3 rd position.

Here, when the user grips the side of the front end side of the upper casing 2 and lifts the upper massage mechanism 11 upward again with a certain force about the axial center of the 1 st rotation shaft 12 (swing shaft 31), the upper massage mechanism can be moved to the "3 rd position".

In the "3 rd position" shown in fig. 9, the 1 st massage member 13 is provided in a state of being pushed in backward and stands obliquely upward backward. The 1 st treatment concave portion 7 is opened upward and forward and backward.

The 1 st massaging member 13 applies a pressing massaging action to the leg T (1 st treatment portion) inserted into the 1 st treatment recess 7 so as to push the leg T from the outside at the "3 rd position". Further, the upper massage mechanism 11 is fixed by sandwiching the leg T.

Specifically, as shown in fig. 9, the upper end side of the 1 st massage member 13 covers the upper portion of the leg T from the side, and the central portion in the longitudinal direction covers the leg T from the side, and the pressing massage operation is applied to the entire leg T so as to press the leg T from the outside and the inside.

When the above-described sequence is reversed, the massage position can be switched (restored) again at the "1 st position", the "2 nd position", or the like. The massage positions "1 st position" to "3 rd position" in the present embodiment are examples, and are not limited to the angles of the illustrated upper massage mechanism 11.

As described above, as described in the description of the present invention, the upper massage mechanism 11 is supported so as to be swingable about the axis in the left-right direction by the swing support portion 30, and is used by being switched to any one of the predetermined massage positions ("1 st position" to "3 rd position") in the front-rear direction, that is, by being configured so that the position of the 1 st massage portion is changeable, for example, in a state in which the user is sitting on a chair or the like, the upper massage mechanism 11 can apply a pressing massage to the treatment portion of any one of the lower limbs L such as the calf C or the leg T. At the same time, the foot F may be given a pressing massage by the lower massage mechanism 37.

The embodiments disclosed herein are to be considered in all respects as illustrative and not restrictive.

In particular, items not explicitly shown in the embodiments disclosed herein, such as working conditions, operating conditions, and sizes and weights of components, are not out of the range of ordinary implementation by those skilled in the art, and can be easily adopted by those skilled in the art.

For example, the lower limb massage machine 1 of the present invention may be provided with an air supply pump and a heating device for heating air from the air supply pump. That is, the heat treatment device may be configured to heat the vicinity of the 1 st massage member 13 and the 2 nd massage member 39 to warm-heat massage the treatment portion such as the foot F, calf C, and leg T by blowing warm air heated by the heating device into the lower limb massage machine 1.

The lower limb massage machine 1 of the present invention may further include an air bag member for applying a pressing massage to the treatment portion of the user. The pair of 1 st massaging members 13 may be provided with a pair of air bag members, and the pair of 2 nd massaging members 39 may be provided with a pair of air bag members.

Further, the lower limb massage machine 1 of the present invention may be provided with a positioning mechanism capable of stopping the swing of the upper massage mechanism 11. That is, the positioning mechanism is also configured to stop the swing of the upper massage mechanism 11 at a predetermined position (massage position) in the front-rear direction by engaging the upper massage mechanism 11 at the predetermined position via the positioning mechanism.

The positioning means may be provided in the vicinity of the swing support portion 30, that is, in the center of the upper massage mechanism 11. In addition, for example, a ratchet mechanism that can be adjusted stepwise may be used as the positioning mechanism.

Although the cylindrical members 55 are attached to the 1 st rotation shaft 12 between the pair of 1 st massaging members 13, protrusions for pressing the treatment parts (calf C, rear side of leg T, etc.) may be provided on the outer peripheral surface of the cylindrical members 55 as the rotary massaging members.

The materials forming the upper case 2 and the lower case 8 are not limited. The upper case 2 and the lower case 8 may be formed of a hard material such as plastic, or the upper case 2 and the lower case 8 may be formed of a soft material such as cloth.

For example, the intensity and rhythm of the massage action applied to the lower limb L may be changed. Further, one or both of the upper massage mechanism 11 and the lower massage mechanism 37 may be provided with a configuration in which the size of the lower limb of the user is detected, and the width adjustment mechanism 35 is linked to adjust the widths of the pair of massage members (the 1 st massage member 13 and the 2 nd massage member 39) based on the detected size. The width adjustment mechanism 35 is most preferably a mechanism disclosed in japanese patent application laid-open No. 2017-153734. The massage device may further include a mechanism for adjusting the swing angle of the pair of massage members (1 st massage member 13 and 2 nd massage member 39).

When the lower limb massage machine 1 disclosed in fig. 1 and the like is used as the leg rest 73, the extension (sliding amount) of the leg rest 73, the angle of raising and lowering of the leg rest 73, and the jump-up angle of the 1 st massage member 13 may be detected in advance. In this way, the appropriate values of the extension amount of the foot rest 73 and the jump-up angle of the 1 st massage member 13 can be determined based on the obtained sliding amounts and the respective angles.

That is, the chair-type massage machine 70 and the lower limb massage machine 1 (leg rest 73) of the present invention preferably have the following configurations. The structure of the present invention (type, shape, detection means, etc. of the member to be used) to be mentioned at present is an example and is not limited to the following.

Since the foot rest 73 may be inclined in the vertical movement direction (expansion/contraction), the upper side when the foot rest 73 is placed on the floor is referred to as the upper side and the lower side (bottom) is referred to as the lower side, depending on the swing motion, which is not strictly the vertical direction.

As shown in fig. 10 to 15, a lower limb massager 1 (leg rest 73) for massaging the feet F and the like is provided on the front side of a chair-type massager 70 having a seat 71 for accommodating a mechanism for massaging the buttocks and the like of a seated user and a backrest 72 for accommodating a mechanism for massaging the back and the like of the user.

The lower limb massage machine 1 includes an upper massage mechanism 11 for imparting kneading massage to the calf C and the like. The upper massage mechanism 11 rotates the lower massage mechanism 37 in the up-down direction about the 1 st rotation shaft 12 in the left-right direction about the axial center by means of the swing drive mechanism 75.

As shown in fig. 15, the swing drive mechanism 75 is provided below the drive mechanism 23 and is attached to the base body 15. The swing drive mechanism 75 includes: a drive motor 76 that outputs a rotational drive force; a rotation shaft 77 rotated by its rotation driving force; a gear 78 mounted on the rotation shaft 77 thereof and accompanying rotation; and a gear 79 engaged with the gear 78 and mounted to the base body 15.

The drive motor 76 is provided with an output shaft directed upward. The rotation shaft 77 is provided with its axis oriented in the right-left direction and orthogonal to the output shaft. Gear 78 is provided adjacent the output shaft. The gear 79 is disposed above the gear 78 and is attached to the 1 st rotation shaft 12 and rotates with it.

When the rotational driving force is output from the driving motor 76, the rotation shaft 77 is rotated by the rotational driving force, and the gear 78 is rotated together with the rotation of the rotation shaft 77. The rotation of the gear 78 rotates the gear 79, and the base body 15 rotates about the 1 st rotation axis 12. Thereby, the 1 st massaging member 13 swings around the 1 st rotation shaft 12 in the front-rear direction.

The upper massage mechanism 11 is provided with a 1 st massage member 13 (kneading plate) for kneading and massaging the calf C to the legs T by the driving mechanism 23. Further, as for the upper massage mechanism 11 thereof, an air bag that repeatedly expands and contracts may be employed.

The lower limb massage machine 1 may be supported so as to be rotatable (swingable) in the front-rear direction by an electric force by means of the rotating mechanism 80.

As shown in fig. 11 to 14, the rotation mechanism 80 includes: a swingable arm member 81 mounted on the front side of the seat portion 71 (support frame 74); a link arm member 82 rotatably coupled to the arm member 81; and a driving portion 83 for moving the link arm member 82 in the front-rear direction.

The arm member 81 is attached to the front side of the support frame 74 and is rotatable in the up-down direction about the shaft center 81 a. The arm member 81 is coupled to a side support member 84 that supports the lower limb massage machine 1. The side support members 84 are provided in a pair on the left and right sides so as to sandwich the leg rest portion 73, and support the leg rest portion 73 from the side. The driving unit 83 is an actuator (linear motion mechanism) in the present embodiment.

When the actuator 83 outputs a driving force, the link arm member 82 coupled to the actuator 83 is pushed forward or pulled backward. The arm member 81 coupled to the link arm member 82 rotates about the shaft center 81 a. When the side support member 84 is rotated (swung) in the vertical direction by the rotation of the arm member 81, the lower limb massage machine 1 (leg rest 73) is rotated up and down around the shaft center 81a on the front side of the seat 71 (support frame 74). Thereby, the position (height) of the lower limb massage machine 1 (leg rest 73) in the up-down direction can be changed.

The lower limb massage machine 1 is composed of an upper massage mechanism 11 and a lower massage mechanism 37. A safety switch (limit switch, pressure sensor, etc.) is provided above the lower massage mechanism 37.

The safety switch is not shown but is mounted on the upper edge of the 2 nd massaging member 39. The safety switch is configured to transmit a signal to the control unit when it is determined that a foreign matter (for example, a hand other than the user (a child or the like)) is present between the safety switch and the upper massage mechanism 11 (the 1 st massage member 13) rotating in the up-down direction, and the rotation is prevented (touched). The control unit issues an instruction to the stopping unit based on the signal. The stopping portion immediately stops the rotation of the upper massage mechanism 11 in the up-down direction. The safety switch is incorporated in a safety adjustment mechanism described later.

The lower limb massage machine 1 is provided with a sensor (not shown) for grasping the rotational position of the upper massage mechanism 11. That is, the sensor recognizes the position of the 1 st massaging member 13 when being swung in the up-down direction about the 1 st rotation axis 12 in an electric manner by the swing driving mechanism 75. Examples of the sensor that detects an arbitrary position include a limit switch and a rotation sensor such as a rotary encoder (rotary encoder).

For example, a rotation sensor for detecting the rotation of the lower massaging machine 1 is provided in advance, and if the detection value of the rotation sensor does not match the rotation instruction given in advance, it can be determined that foreign matter is trapped between the upper massaging mechanism 11.

The lower limb massage machine 1 is provided with a sensor (not shown) for grasping the rotational position of the main body of the lower limb massage machine 1. That is, the sensor recognizes the position of the body of the lower limb massage machine 1 when the body swings in the up-down direction about the shaft center 81a of the arm member 81 by the rotating mechanism 80 in an electric manner.

Examples of the sensor that detects an arbitrary position include a limit switch (means for detecting the position of the slider 87 that moves at one end and the other end of the actuator 83 (driving unit)), and a rotation sensor (means (rotary encoder, etc.) that detects the rotation of the screw member (rod 83a that moves the slider 87) of the actuator 83, for example).

The lower limb massage machine 1 is configured to extend and retract electrically to the front side of the seat 71. That is, the lower limb massage machine 1 is configured to move in the vertical direction by the vertical movement mechanism 86 (described in detail later). Further, the upper massage mechanism 11 and the lower massage mechanism 37 may be expanded, that is, the body of the lower limb massage machine 1 may be expanded in the vertical direction.

The lower limb massage machine 1 is provided with a sensor (not shown) for grasping the telescopic position of the main body of the lower limb massage machine 1. That is, the sensor recognizes the position of the lower limb massage machine 1 when it is moved in the up-down direction by the up-down movement mechanism 86 in an electric manner.

Examples of the sensor that detects an arbitrary position include a limit switch (means for detecting the position of the slider 91 that moves at one end and the other end of the actuator 89 (lift driving unit)), and a rotation sensor (means (rotary encoder, etc.) that detects the rotation of the screw member (rod 89a that moves the slider 91) of the actuator 89, for example).

The maximum rotation angle of the upper massage mechanism 11 is limited by at least one of a height position generated by the vertical rotation of the body of the lower limb massage machine 1 and a telescopic position when the body of the lower limb massage machine 1 is telescopic in the extending direction (vertical direction).

That is, the maximum value (allowable range of swing) of the rotation angle of the 1 st massage member 13, which is limited when the 1 st massage member 13 is rotated to be raised and lowered by the swing drive mechanism 75, may be determined depending on the position (height, extension, etc.) at which the body of the lower limb massage machine 1 is present.

The upper massage mechanism 11 (1 st massage member 13) rotates around an axis in the left-right direction. The axis is the same as the 1 st rotation axis 12 (kneading axis).

Further, the upper massage mechanism 11 and the lower massage mechanism 37 are driven by the same drive motor 24.

The kneading width of the upper massage mechanism 11, that is, the width of the pair of 1 st massage members 13 is changed by the width adjusting mechanism 35. For example, when the upper massage mechanism 11 is rotated (swung) in the vertical direction from the calf C toward the leg T, the kneading width (the interval between the pair of 1 st massage members 13) is enlarged by the width adjustment mechanism 35 and then rotated. That is, the kneading width (the interval between the pair of 1 st massaging members 13) may be changed according to the thickness of the lower limb of the user.

The lower limb massage machine 1 may be configured such that the main body rotates about a shaft (1 st rotation shaft 12) oriented in the lateral direction. The lower limb massage machine 1 is rotated (reversed) by 90 to 180 degrees around the axial center of the rotation shaft 88, and can be used as a footrest (ottoman). That is, by turning the lower limb massage machine 1 upside down (rotating with the bottom surface side being the upper surface and the 2 nd treatment recess 9 side being the lower side), the footstool on which the leg portion F can be placed is formed on the bottom surface or the rear wall surface side located on the upper side.

In addition, the rotation angle of the body of the lower limb massage machine 1 (the rotation angle for switching to the footrest) is preferably 90 degrees with respect to the rotation shaft 88.

The lower limb massage machine 1 is provided with a sensor 85 for detecting a position at which the main body is switched to the footrest state. When the lower limb massage machine 1 is in the footrest state, a signal is transmitted to the control unit by means of position detection, and the upper massage mechanism 11 is controlled not to perform a rotational motion.

In the present embodiment, 2 limit switches 85a for identifying the stool state and 2 limit switches 85b for identifying the foot massaging position are provided on the side support member 84 (left side in the present embodiment) (see fig. 11 to 15, etc.).

The lower limb massage machine 1 is preferably configured to be capable of performing an extension (stretch) operation on the lower limb of the user as described below.

That is, the pair of 2 nd massage members 39 provided in the lower massage mechanism 37 may be turned upward while the pair of 1 st massage members 13 provided in the upper massage mechanism 11 are closed to sandwich the lower limb L of the user in a state where the feet F of the user are restrained.

The body of the lower limb massage machine 1 may be lowered while the pair of 1 st massage members 13 provided in the upper massage mechanism 11 are closed (the state of the leg being sandwiched by the leg T, calf C, etc.), or the lower limb massage machine 1 may be moved by electrically extending the up-and-down movement mechanism 86 while the 1 st massage members 13 are rotated downward (moved so as to hang down).

The lower limb massage machine 1 may be lowered while the 1 st massage member 13 is rotated downward (moved in a hanging manner) or the lower limb massage machine 1 may be moved in an electrically extended manner by the up-and-down movement mechanism 86, in a state where the 1 st massage member 13 provided in the upper massage mechanism 11 is closed (a state where the leg is clamped by the leg T, the calf C, or the like), or in a state where the 2 nd massage member 39 provided in the lower massage mechanism 37 is closed to restrain the foot F.

In addition, although not shown, the pair of 1 st massage members 13 provided in the upper massage mechanism 11 may be driven in a state where they are closed at the positions of the legs T, for example, by repeating the operation of expanding and contracting the air bag provided in the seat 71 or by driving at least one of the seat massage mechanism provided in the seat 71 to move in the front-rear direction, the kneading, the hammering, and the advancing-retracting operation in the up-down direction.

As shown in fig. 11 and the like, the knee is located in the extension and contraction direction (upward) of the lower limb massage machine 1. Therefore, the pair of 1 st massaging members 13 are controlled so as not to perform the kneading action at the position corresponding to the knee. That is, in the region where the knee is located, a kneading stop region is provided.

Further, a heater for heating the lower limb may be mounted on the upper massage mechanism 11. When the upper massage mechanism 11 reaches a position corresponding to the knee (kneading stop area), the mounted heater is activated (ON) and heated. In addition, the position other than the kneading stop region (calf C, leg T, etc.) may be controlled so that the heater is activated (ON) to heat the whole lower limb (treatment part). The lower massage mechanism 37 may be provided with a heater to heat the leg F.

Further, the upper massage mechanism 11 may be provided with a mode in which the 1 st massage member 13 of the upper massage mechanism 11 is lifted up in advance and the pair of 1 st massage members 13 are closed to sandwich the legs T, and the entire legs T are massaged by rotating or reciprocating the upper massage mechanism 11 in one direction.

Further, the upper massage mechanism 11 may be provided with a mode in which the entirety of the calf C is massaged by rotating or reciprocating the upper massage mechanism 11 in one direction while the 1 st massage member 13 of the upper massage mechanism 11 is suspended and while the pair of 1 st massage members 13 are closed to sandwich the calf C.

The detection of the raising and lowering angle of the leg rest 73, the detection of the extension amount (sliding amount) of the leg rest 73, and the detection of the jump-up angle of the 1 st massage member 13 are also repeated, but will be described in more detail.

Specifically, the leg rest 73 (lower limb massage machine 1) is electrically rotated in the up-down direction by the rotating mechanism 80, and simultaneously electrically slid in the up-down direction by the up-down moving mechanism 86, on the front side of the seat 71. Further, the 1 st massaging member 13 is swung in the up-down direction electrically by the swing driving mechanism 75.

The lower limb massage machine 1 is configured to be vertically rotated by being electrically lifted or lowered in the vertical direction through a swingable arm member 81 attached to the front side of the support frame 74, with the axis 81a of the arm member 81 as a base point.

The lower limb massage machine 1 is laterally supported by a pair of left and right lateral support members 84. The side support member 84 is a plate member and is coupled to the L-shaped arm member 81. The arm member 81 is attached to the front side of the support frame 74 so as to be swingable about the shaft center 81a in the up-down direction. The lower limb massage machine 1 is rotatably supported by the seat 71 via the side support member 84 and the arm member 81.

A link arm member 82 rotatably coupled to the arm member 81 and a driving portion 83 for moving the link arm member 82 in the front-rear direction are provided at a lower portion of the seat portion 71 (support frame 74). That is, the lower limb massage machine 1 is supported rotatably in the vertical direction by a rotation mechanism 80 constituted by an arm member 81, a link arm member 82, and a driving section 83.

In the present embodiment, the driving unit 83 employs a linear motion mechanism (actuator) to perform a linear motion along the front-rear direction of the seat 71. Here, the structure of the driving portion 83 is not limited to the actuator.

The link arm member 82 is protruded and retracted in the front-rear direction from the support frame 74 by driving of the driving portion 83. The arm member 81 and the side support member 84 may be integrally formed.

The lower limb massage machine 1 is provided with a safety adjustment mechanism for safely adjusting the angle (swing angle) of the ascent and descent of the body of the lower limb massage machine 1. The safety adjustment mechanism has: a detection unit for detecting the position of the slider 87 provided in the driving unit 83 (actuator) in the front-rear direction, and a stop unit for stopping the vertical rotation of the lower limb massage machine 1 based on the detection result of the detection unit.

That is, the safety adjustment mechanism detects the ascending and descending positions of the lower limb massage machine 1 based on the position of the slider 87 provided in the driving unit 83 (actuator), and safely adjusts the position to a predetermined position by the instruction of the control unit.

The detection unit transmits a stop signal to the control unit, for example, when the detection unit has reached an arbitrary position according to the user, when the detection unit has reached a limit position of vertical rotation, or the like. The stopping unit stops the driving unit 83 according to a stop signal from the control unit.

As the detection unit, for example, a sensor for detecting a stroke position may be provided in the actuator 83, or limit switches may be provided at both ends of the movable range. The detection unit may be configured to detect the rotation angle of the arm member 81 rotating around the shaft center 81 a. That is, the detection unit is not limited to the illustrated position as long as it can detect the position (arbitrary position) of the up-and-down rotation of the lower limb massage machine 1.

When the slider 87 reaches a predetermined position when the lower limb massage machine 1 is rotated in the vertical direction, the position of the slider 87 is detected by the detection unit, and the stop unit is caused to stop driving of the actuator 83 based on the detection result, so that the position (rotation angle) of the lower limb massage machine 1 to be raised and lowered is safely adjusted.

The side support member 84 is provided with a rotation shaft 88 whose axis is oriented in the left-right direction. That is, the lower limb massage machine 1 is switched to a footrest capable of placing the lower limb by rotating around the axis of the rotation shaft 88 and moving the bottom surface to the upper surface. When the footstool is in the state, the upper massage mechanism 11 is controlled not to be rotated up and down while maintaining the state.

As shown in fig. 11 to 13, when the lower limb massage machine 1 is switched to the footrest state, the position is recognized by the sensor 85 (limit switch 85 a) attached to the side support member 84 (left side in the present embodiment), a signal is transmitted according to the position, and the upper massage mechanism 11 is stopped according to the instruction of the control unit.

When the lower limb massage machine 1 has been switched to the foot massaging position, the position is recognized by the sensor 85 (limit switch 85 b) attached to the side support member 77, and a signal is transmitted based on the position, so that the upper massage mechanism 11, the lower massage mechanism 37, and the like can be driven in accordance with the instruction of the control unit.

The lower limb massage machine 1 is configured to extend and retract in the up-down direction (move in the body length direction of a seated user) by the up-down movement mechanism 86.

The up-and-down movement mechanism 86 includes: a lift drive unit 89 that generates a driving force for moving the lower limb massage machine 1 in the up-down direction; and a slide member 90 for moving the lower limb massage machine 1 in the up-down direction.

The lifting drive unit 89 is provided on the back side of the lower limb massage machine 1. In the present embodiment, the elevation driving unit 89 employs a linear motion mechanism (actuator) to perform a linear motion in the vertical direction along the rear wall surface of the lower limb massage machine 1. Here, the structure of the elevation driving part 89 is not limited to the actuator.

The slide member 90 is provided on the back wall surface of the lower limb massage machine 1, and a slider 91 of the elevation drive unit 89 is attached thereto. The slide member 90 moves in the up-down direction by the linear movement of the elevation drive section 89.

The safety adjustment mechanism is provided with a mechanism for safely adjusting the extension (slip amount) of the lower limb massage machine 1. The safety adjustment mechanism has: an up-down detection section for detecting the position of the slider 91 provided in the up-down drive section 89 (actuator); and an up-and-down stopping unit for stopping the up-and-down moving mechanism 86 (the lower limb massage machine 1) based on the detection result of the up-and-down detecting unit.

That is, the safety adjustment mechanism detects the position of the lower limb massage machine 1 in the up-down direction from the position of the slider 91 provided in the elevation drive unit 89 (actuator), and safely adjusts the position to a predetermined position by the instruction of the control unit.

The up-down detection unit transmits a stop signal to the control unit, for example, when the user has reached an arbitrary position, when the bottom of the lower limb massage machine 1 has contacted the sole of the foot inserted into the 2 nd treatment recess 9, or when the load exceeds a predetermined value, or when the user has reached a limit position of up-down movement. The stopping unit stops the elevation driving unit 89 according to a stop signal from the control unit.

The up-down detection unit may be provided with a sensor for detecting a stroke position in the actuator 89, or may be provided with limit switches at both ends of the movable range. That is, the vertical detection unit is not limited to the illustrated position as long as it can detect the position (arbitrary position) where the lower limb massage machine 1 extends in the vertical direction.

When the slider 91 reaches a predetermined position when the lower limb massage machine 1 is vertically moved, the position of the slider 91 is detected by the vertical detection unit, and the stop unit is caused to stop driving of the actuator 89 based on the detection result, so that the extension amount (slip amount) of the lower limb massage machine 1 is safely adjusted to a predetermined amount.

The vertical detection unit may be configured to detect a situation in which the vertical movement of the lower limb massage machine 1 is obstructed (for example, a situation in which a foreign matter is suddenly caught, a situation in which the vertical movement is at a limit, or the like). The upper and lower detection unit may be configured to detect a distance between the rear edge of the lower limb massage machine 1 and the front edge of the seat 71.

The safety adjustment mechanism is provided with a mechanism for safely adjusting the jump-up angle of the 1 st massage member 13 to a predetermined angle. The safety adjustment mechanism is provided with: an axis angle detection unit for detecting the rotation angle of the 1 st rotation axis 12; and a stopping portion for stopping the swing of the 1 st massage member 13 (driving of the driving mechanism 23) based on the detection result of the shaft angle detecting portion.

The safety adjustment mechanism may further include a position detection unit that detects the limit position of the swing of the 1 st massaging member 13. That is, the jump-up angle of the 1 st massage member 13 is detected by the safety adjustment mechanism, and is safely adjusted to a predetermined position by an instruction of the control unit.

The shaft angle detection unit may be attached to the 1 st rotation shaft 12. The shaft angle detection unit may be, for example, a rotary encoder or the like.

The position detecting unit may detect the position of the upper end that is reached when the 1 st massaging member 13 is raised, based on the position of the lower limb massaging machine 1. The position detecting unit may be configured to detect a distance between the edge of the 1 st massage member 13 lifted and the front edge of the seat 71. With this detection, the reachable position of the 1 st massage member 13 when standing up is changed according to the distance between the upper portion of the lower limb massage machine 1 and the front edge of the seat 71.

When the 1 st rotation shaft 12 is set to a predetermined rotation angle while the 1 st massage member 13 is swinging in the front-rear direction, the rotation angle of the 1 st rotation shaft 12 is detected by the shaft angle detection unit, and the rotation of the 1 st rotation shaft 12 is stopped by the stopping unit by a command from the control unit according to the detection result, and the swinging of the 1 st massage member 13 is stopped at the determined position.

That is, as shown in fig. 11, for example, when the lower limb massage machine 1 is inclined rearward and the slide member 84 is located at a middle portion in the vertical direction, that is, at a middle position of the lower limb massage machine 1, the safety adjustment mechanism jumps the 1 st massage member 13 upward and slightly forward of the lower limb massage machine 1 so that the 1 st massage member 13 does not contact the front side of the seat 71 by a command from the control unit.

On the other hand, as shown in fig. 12, for example, when the lower limb massage machine 1 is inclined rearward and the slide member 84 is located on the upper end side (upper limit point), that is, at the lowermost position of the lower limb massage machine 1, the safety adjustment mechanism causes the 1 st massage member 13 to jump up rearward above the lower limb massage machine 1 so that the 1 st massage member 13 does not come into contact with the front side of the seat 71 by a command from the control unit.

That is, when the distance between the upper part of the lower limb massage machine 1 and the front edge of the seat 71 is short as shown in fig. 11, the 1 st massage member 13 jumps up slightly forward from the upper part of the lower limb massage machine 1, and when the distance is long as shown in fig. 12, the 1 st massage member 13 jumps up slightly rearward from the upper part of the lower limb massage machine 1.

As is also apparent from fig. 11, 12, etc., the jump-up angle of the 1 st massaging member 13 is adjusted to an appropriate angle by the safety adjustment mechanism, and contact with the seat 71 due to the rearward inclination of the 1 st massaging member 13 can be avoided.

The detected position of the lower limb massage machine 1, the jump-up angle of the 1 st massage member 13, and the like may be stored as data in the control unit or the like.

The safety adjustment mechanism may be configured such that the detection unit determines that the movement is obstructed by the presence of a foreign object (e.g., a hand other than the user (e.g., a child), and the stop unit immediately stops the driving of the up-and-down movement mechanism 86 to stop the movement of the lower limb massage machine 1. When the forward/backward swing of the lower limb massage machine 1 is obstructed, the swing may be stopped immediately.

According to the present invention, even in various situations where the length (height) of the lower limb of the user is different, the massage operation can be properly and safely applied to the treatment portion. Further, with the structure of the present invention, the upper massage mechanism 11 can be prevented from contacting other members such as the seat 71.

In the present invention, the basic device configuration of the upper massage mechanism 11 and the lower massage mechanism 37 is not particularly limited. That is, various mechanisms can be used as the upper massage mechanism 11 and the lower massage mechanism 37.
