[Form of implementing the invention]

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

1 to 5 show an embodiment of the massage machine 1 for lower limbs of the present invention.

The lower extremity massage machine 1 of the present embodiment is configured such that the lower extremities on the left and right sides of the user are used as massage objects (treatment parts), and both the feet and the calf constituting the lower extremities are simultaneously massaged by kneading or linear massage. Mobile pressing massage (shiatsu massage).

In addition, in this specification, "calf" refers to the part below the knee and above the ankle in the lower limbs of the human body, and "foot" refers to the part below the ankle. Furthermore, the directions mentioned in the description have been appropriately shown in the drawings, and are consistent with the front-rear direction, the left-right direction, and the up-down direction when viewed from the user who uses the lower extremity massage machine 1 .

The massaging machine 1 for legs of this embodiment has the housing 2 which has a square shape in a front view and a boot shape (L shape) in a side view. On the front surface of the casing 2, a pair of left and right treatment concave portions 9 that are open to the front and upward are arranged side by side apart from each other. Inside these left and right treatment concave portions 9, there are provided inner linings having elasticity and flexibility and having appropriate air permeability.

As shown in FIG. 2, the housing 2 is provided with a base frame portion 2a, and a support frame having a back frame portion erected at the rear end of the base frame portion 2a and having an L-shaped side view. The base frame portion 2a is provided with a horizontal massage mechanism 3, and the back frame portion is provided with a vertical massage mechanism 4.

In addition, the names of "horizontal" and "vertical" of the horizontal massage mechanism 3 or the vertical massage mechanism 4 are only expedient descriptions in this specification, and do not limit the use state of the massage machine 1 for lower limbs.

First, the horizontal massage mechanism 3 (foot massage mechanism) will be described.

As shown in FIG. 2 to FIG. 5 etc., the horizontal massage mechanism 3 includes: a pair of left and right massage members 5, 5, which are arranged side by side in the left and right direction to the extent that they can be inserted into the feet; a pressing member 6 is provided on the left and right one Between the pair of massage members 5 and 5 ; the first drive mechanism 7 makes the pair of left and right massage members 5 and 5 approach and separate from each other; and the second drive mechanism 8 makes the pressing member 6 actuate.

The massaging members 5 and 5 are a pair of left and right as a set, and this combination is provided in two sets in total so as to correspond to the left and right treatment recesses 9 of the casing 2 . The massaging members 5 are formed in an upright plate shape from a material having elasticity in the thickness direction, and the inner surfaces of the massaging members 5 facing each other are provided with a cushioning material, a covering material, etc. that can give a soft touch to the foot.

The first drive mechanism 7 of the horizontal massage mechanism 3 reciprocates a pair of left and right massage members 5 and 5 in a pinching position (refer to FIG. 4 ) for pinching the feet inserted between them, and a releasing position. (refer to FIG. 3 ), a massage action is given to the foot by a kneading method. The first drive mechanism 7 drives the two sets of massage members 5 and 5 simultaneously.

The first drive mechanism 7 includes: a rotating shaft 10 provided in a direction (left-right direction) penetrating between the massage members 5 and 5; a drive motor 11 (electric motor) for rotationally driving the rotating shaft 10; and a conversion portion for converting The rotational driving force of the rotating shaft 10 is converted into the massage action of the massage member 5 .

The drive motor 11 is switchable between forward rotation driving and reverse rotation driving, and transmits a rotational driving force to the rotating shaft 10 through a speed reduction portion provided with a worm and a worm gear meshed with the worm.

The conversion part has an inclined protrusion 13 , which is provided at the portion where the rotating shaft 10 penetrates the massage member 5 , and the rotating shaft 10 passes through the center part thereof, and the outer periphery has a cam groove inclined to the rotating shaft 10 .

In the case of the present embodiment, the one-way clutch mechanism 14 is provided between the inclined protrusion 13 and the rotating shaft 10 . Therefore, when the drive motor 11 is driven forward and the rotating shaft 10 is rotated forward, the rotational driving force of the rotating shaft 10 is transmitted to the inclined protrusion 13, and the rotating shaft 10 and the inclined protrusion 13 are integrated in the same direction. rotate. On the other hand, when the drive motor 11 is driven in reverse and the rotating shaft 10 is reversed, the inclined protrusions 13 are in an idling state for the rotating shaft 10 , and the rotational driving force of the rotating shaft 10 is not transmitted to the inclined protrusions 13 .

In addition, the details of the one-way clutch mechanism 14 will be described later.

An annular fitting portion 15 provided at the base end of the massage member 5 is fitted to the outer peripheral edge of the inclined protrusion 13 via a bearing, and the massage member 5 is kept in a state of being rotatable relative to the rotating shaft 10 .

Furthermore, the conversion part has a structure in which the restriction protrusion 16 protruding downward from the massage member 5 is engaged with the horizontally long hole 17 provided in the base frame part 2a of the support frame, etc., which is long in the left-right direction. Since the restricting protrusions 16 are engaged with the horizontally long holes 17 and the restricting protrusions 16 slide in the horizontally long holes 17 , the massage member 5 will not rotate (driven rotation) with the inclined protrusions 13 . That is, when the rotating shaft 10 rotates, the inclined protrusions 13 swing around the rotating shaft 10 in the left-right direction corresponding to the inclined component, and only the swing component at this time is transmitted to the massage member 5.

The inclination direction in which the inclined protrusion 13 inclines with respect to the rotating shaft 10 is set to be relatively opposite between the massage members 5 and 5 . Therefore, after the pair of right and left massage members 5 and 5 approach each other, a so-called separation swing operation is performed. When the pair of massage members 5 and 5 on the left and right are close to each other, the feet placed between the massage members 5 and 5 will be pinched, and a pressing massage action will be performed from the left and right.

When the pair of left and right massage members 5 and 5 are separated from each other, the feet placed between the massage members 5 and 5 are released. By continuously rotating the rotating shaft 10 , the massage members 5 and 5 can alternately and repeatedly perform the aforementioned pinching and releasing operations, and simultaneously perform undulating swings within a predetermined angle range.

The above-mentioned actions are actions that occur when the rotary shaft 10 rotates in the forward direction. That is, when the rotating shaft 10 rotates forward, the rotational driving force of the rotating shaft 10 is transmitted to the inclined protrusion 13 by the one-way clutch mechanism 14, and the rotating shaft 10 and the inclined protrusion 13 integrally rotate in the same direction. The massage member 5 is driven to swing.

On the other hand, when the rotating shaft 10 is reversed, the one-way clutch mechanism 14 makes the inclined protrusion 13 idling with respect to the rotating shaft 10 , and the rotational driving force of the rotating shaft 10 is not transmitted to the inclined protrusion 13 . Therefore, although the massage member 5 is stopped while maintaining the pinched state of the foot or the released state of the foot, the pressing member 6 described later is driven.

On the other hand, as shown in FIG. 2 or FIG. 5 , the pressing member 6 for pressing and massaging the soles of the feet includes: a rotating rotor 20 provided so as to be integrally rotatable with respect to the rotating shaft 10 provided in the first driving mechanism 7; and a plurality of The projections are dispersed and arranged on the outer peripheral surface of the rotating rotor 20 with a predetermined interval in the circumferential direction and the axial direction.

The second drive mechanism 8 that drives the pressing member 6 presses the foot portion inserted between the pair of left and right massage members 5 and 5 upward by rotating the rotating rotor 20 and the rotating shaft 10 integrally. The way the soles of the feet (forefoot, arch, heel) impart massage action.

When the rotating rotor 20 is rotated by the rotation of the rotating shaft 10, according to the rotating direction of the rotating shaft 10, the plurality of protrusions can be selected to move from the rear side to the front side while pressing the sole of the foot, or vice versa. .

In the case of this embodiment, the pressing member 6 which presses and massages the sole has a more complicated structure.

The pressing member 6 of the present embodiment includes a first massaging member 20 for massaging the central portion of the sole of the user's foot, a second massaging member 21 for massaging the rear portion of the sole of the user's foot, and a third massaging member for massaging the front portion of the sole of the user's foot The member 22 can generate a massage action on the sole of the foot by driving the first massaging member 20 to the third massaging member 22 in linkage.

The first massage member 20 is the aforementioned rotating rotor 20 that provides a pressing massage action to the center portion of the sole of the foot.

The arm-shaped first connecting piece 23 is provided so as to extend rearward from the first massage member 20 (rotating rotor), and the first connecting piece 23 is rotatable in a state where the base end is eccentric with respect to the rotating shaft 10 . A second massage member 21 is provided at the front end portion, and is configured such that the second massage member 21 connected to the first connecting piece 23 performs a swinging movement by the rotational movement of the rotating shaft 10 .

Furthermore, an arm-shaped second connecting piece 24 is provided, which is formed to extend forward from the first massage member 20 (rotating roller), and the second connecting piece 24 is in a state where the base end portion is eccentric with respect to the rotating shaft 10 . It is rotatably mounted, and the front end portion is provided with a third massaging member 22 , and is configured to slide and swing the third massaging member 22 connected to the second connecting piece 24 in the front-rear direction by the rotational movement of the rotating shaft 10 .

The second massaging member 21 and the third massaging member 22 are formed with a plurality of protrusions 25 protruding upward, and the soles of the feet can be effectively massaged by these protrusions.

The first connecting piece 23 and the second connecting piece 24 described above are integrally formed so that the base end portions of the respective connecting pieces are at the same position.

As mentioned above, in the massaging machine 1 for legs of this embodiment, the one-way clutch mechanism 14 is provided between the inclined protrusion part 13 and the rotating shaft 10 .

The one-way clutch mechanism 14 is constituted by a one-directional power transmission portion 40 and a braking portion 50 .

As shown in FIGS. 6 and 7 , the unidirectional power transmission portion 40 is provided on the inner side of the inclined protrusion portion 13 in the width direction, and as shown in FIGS. 6 and 8 , the braking portion 50 is provided in the width of the inclined protrusion portion 13 . direction outside.

As shown in FIGS. 6 and 7 , the unidirectional power transmission portion 40 has a snail-shaped protruding portion 42 fitted into the inclined protruding portion 13 in a loosely fitted state. In the snail-shaped protruding portion 42 , the rotating shaft 10 penetrates through the central portion thereof, and is fixed to the rotating shaft 10 so as to be accompanied by rotation.

A cam groove 43 having a spiral shape in a side view is formed on the outer peripheral edge of the snail-shaped protrusion 42 . Specifically, the radius of the cam groove 43 is the largest at the position of the angle of 0 degrees, and the radius of the cam groove 43 decreases as it rotates in the counterclockwise direction. Therefore, the radius reaches the shortest point just before the complete circle (angle 360 degrees). Therefore, a steep cliff portion 44 (position regulating portion) is formed at a position of an angle of 360 degrees (in other words, an angle of 0 degrees). The cam groove 43 is shaped like a snail shell in a side view. In each massage member 5 , the cliff portion 44 is formed at a predetermined position with respect to the circumferential direction of the rotating shaft 10 .

For example, by setting the position corresponding to the cliff portion 44 and the pressing member 5 held by the right foot, and the position corresponding to the cliff portion 44 and the pressing member 5 held by the left foot at the same position with respect to the circumferential direction of the rotating shaft 10, When the right foot is held and pressed, the left foot can be held and pressed in the same manner. That is, the pressing member 5 corresponding to the right foot and the pressing member 5 corresponding to the left foot can be swung in the same phase. On the other hand, the position of the cliff portion 44 corresponding to the pressing member 5 held by the right foot and the position of the cliff portion 44 corresponding to the pressing member 5 held by the left foot are shifted by 90 degrees with respect to the circumferential direction of the rotating shaft 10 Or 180 degrees, for example, when pressing the right foot (left foot), the left foot (right foot) can be set in a relaxed state or a released state. That is, the pressing member 5 corresponding to the right foot and the pressing member 5 corresponding to the left foot can be swung in different phases.

The bottom of the lower end of the positioning piece 45 can slide on the cam groove 43 of the snail-shaped protrusion 42 . The shape of the positioning piece 45 is in the shape of a corner column, and the longitudinal direction thereof is set toward the radial direction of the snail-shaped protruding portion 42 . On the other hand, the upper end portion of the positioning piece 45 is fitted into the groove portion 46, and the groove portion 46 is slidable in the radial direction. 42), located on the outer side of the radial direction, and toward the radial direction.

When the components in the disassembled state shown in FIG. 7 are assembled, the snail-shaped protruding portion 42 is fitted into the cylindrical recessed portion 47 formed on the radially inner side of the inclined protruding portion 13 in a loose fitting state, and the positioning piece 45 slides on the cam groove 43 of the snail-shaped protrusion 42 , and the upper end of the positioning piece 45 is fitted into the groove 46 of the inclined protrusion 13 .

With this configuration, when the rotating shaft 10 rotates in the forward rotation direction (the direction in which the snail-shaped protrusion 42 is rotated in the clockwise direction when viewed from the direction of FIG. 7 ), the snail-shaped protrusion is formed on the snail-shaped protrusion. The cliff portion 44 of 42 abuts on the side surface of the lower end portion of the positioning piece 45 , so that the snail-shaped protruding portion 42 can rotate together with the positioning piece 45 . In other words, as the rotation shaft 10 rotates in the forward rotation, the positioning piece 45 also rotates in the forward rotation direction.

At this time, since the upper end portion of the positioning piece 45 is formed into the groove portion 46 that fits into the inclined protrusion portion 13, as the rotating shaft 10 rotates forwardly, the inclined protrusion portion 13 also rotates in the forward rotation direction, and is further driven by this rotation. force, so that the massage member 5 can be driven to swing.

On the other hand, when the rotating shaft 10 is rotated in the reverse direction (the direction in which the snail-shaped protrusion 42 is rotated in the counterclockwise direction when the snail-shaped protrusion 42 is viewed from the direction of FIG. 7 ), the positioning piece 45 will be in the snail-shaped protrusion. The cam groove 43 of the protruding portion 42 slides up and does not engage with the cliff portion 44 formed on the snail-shaped protruding portion 42 . When the positioning piece 45 reaches the cliff portion 44 , that is, when the angle of the snail-shaped protruding portion 42 reaches an angle of 0 degrees and reaches an angle of 360 degrees, the positioning piece 45 moves so as to fall from the cliff portion 44 .

It can be seen from this that when the rotating shaft 10 rotates in the reverse direction, the cliff portion 44 does not abut on the side surface of the lower end portion of the positioning piece 45, and the positioning piece 45 only slides on the cam groove 43 of the snail-shaped protrusion 42, and the snail The protruding portion 42 and the positioning piece 45 do not rotate together. Therefore, when the rotating shaft 10 is rotated in the reverse direction, the rotational driving force thereof is not transmitted to the positioning piece 45, and the inclined protrusion 13 is in a non-rotating state. Therefore, the massaging member 5 does not perform a rocking motion, but becomes a stop state.

The swing state and the stop state of the massage member 5 can be switched by the one-directional power transmission portion 40 described above.

However, when the massage member 5 is in a stopped state, in other words, the rotating shaft 10 is reversed and the lower end of the positioning piece 45 slides on the cam groove 43 of the snail-shaped protrusion 42, if a load is applied to the massage member 5 , the lower end of the positioning piece 45 moves arbitrarily in the counterclockwise direction on the cam groove 43 of the snail-shaped protrusion 42 by sloping the protruding portion 13 , and the massage member 5 moves inadvertently.

For example, even if the massage member 5 is stopped by switching the rotating shaft 10 from forward rotation to reverse rotation in a state in which the massage members 5 and 5 are in close proximity (in a state of being pinched into the foot), there will be a reaction by the pinched foot. A load is applied to the massaging member 5 by force, and the massaging member 5 is moved in the direction of separation.

In order to prevent such a loss, the one-way clutch mechanism 14 is provided with a braking portion 50 that prevents the inclined projection portion 13 from rotating in the reverse direction.

As shown in FIG. 8 , the brake portion 50 includes a brake inner ring portion 51 mounted on the outer side in the width direction of the inclined protrusion portion 13 using a mounting ring 55 , and a brake outer ring portion 52 mounted so as to surround the brake inner ring portion 51 . The outer peripheral portion is fixed to the casing (fixed side). The brake outer ring portion 52 is an annular (cylindrical) member, and the brake inner ring portion 51 is fitted into the inner space of the brake outer ring portion 52 in a loosely fitted state.

The brake inner ring portion 51 is an annular member, and a plurality of (eight in the present embodiment) triangular convex portions 53 having a right-angled triangle shape in side view are formed on the outer peripheral surface along the outer peripheral direction of the brake inner ring portion 51. In the vicinity of the apex of the triangular convex portion 53, the distance (gap) from the inner peripheral surface of the brake outer ring portion 52 becomes very narrow, and in the vicinity of the concave portion of the triangular convex portion 53, the distance from the inner peripheral surface of the brake outer ring portion 52 becomes very narrow. (gap) becomes wider.

Further, between the brake inner ring portion 51 and the brake outer ring portion 52 (in other words, in the concave portion of the triangular convex portion 53 ), a gap member 54 is disposed so as to be movable in the concave portion. The gap member 54 is spherical or cylindrical, and its size (diameter) is set to be larger than the gap between the apex of the triangular convex portion 53 and the inner peripheral surface of the brake outer ring portion 52 .

When the rotating shaft 10 rotates in the forward rotation direction (the direction in which the brake inner ring portion 51 rotates in the counterclockwise direction when the brake inner ring portion 51 is viewed from the direction of FIG. It is located in the concave portion formed between the triangular convex portions 53, and the brake inner ring portion 51 and the brake outer ring portion 52 are not connected at all. Therefore, the brake inner ring portion 51 and the brake outer ring portion 52 are in a non-connected state, and cannot function as the brake portion 50 . Therefore, the rotation of the inclined protrusions 13 is not hindered, and the massage member 5 can be surely driven to swing.

Conversely, when the rotating shaft 10 is rotated in the reverse direction (the direction in which the brake inner ring portion 51 is rotated in the clockwise direction when viewed from the direction of FIG. slope and reach the vicinity of the apex of the triangular convex portion 53 . The gap member 54 reaching the vicinity of the vertex of the triangular convex portion 53 engages in the gap between the triangular convex portion 53 (in other words, the brake inner ring portion 51 ) and the brake outer ring portion 52 , so that the brake inner ring portion 51 and the brake outer ring portion 52 are integrally rotated. .

In this state, since the brake inner ring portion 51 is connected to the brake outer ring portion 52 connected to the fixed side (eg, the housing), the brake inner ring portion 51 is in a non-rotating state. Therefore, the rotation of the inclined protrusion 13 connected to the brake inner ring portion 51 is hindered, and the operation of the massage member 5 at this position is suppressed.

Due to the action of the braking portion 50, even if the rotating shaft 10 is switched from forward rotation to reverse rotation and the massage member 5 is stopped in a state where the massage members 5 and 5 are close to each other (the state of being pinched into the foot), the massage member 5 can be stopped. The movement of the massage member 5 moving in the separation direction is surely suppressed by the reaction force of the pinched foot.

In addition, the massage machine 1 for lower limbs is provided with the vertical massage mechanism 4 (calf massage mechanism).

The vertical massage mechanism 4 can be of various types. In the case of this embodiment, as shown in FIG. 1 , the vertical massage mechanism 4 includes: a massage member 30 for pressing the oblique outer and inner sides of the front of the calf; a pressing member 31 , massage the calf from the back side; and lift the driving part 32 to make the massage member 30 and the pressing member 31 move up and down integrally.

The massaging member 30 and the pressing member 31 are set as one set, and two sets are provided in total so that the combination corresponds to the treatment recesses 9 on the left and right of the casing 2 . When the massage member 30 and the pressing member 31 move up and down as a whole, the pressing massage can be effectively applied to the front and rear of the calf.

Next, the operation state of the massage machine 1 for lower limbs (particularly, the horizontal massage mechanism 3 ) of the present embodiment will be described.

First, when the massage machine 1 for lower limbs is in the OFF state of the operation switch 33, the pair of left and right massage members 5 of the horizontal massage mechanism 3 are in an open state. Furthermore, the massage member 5 and the pressing member 6 of the vertical massage mechanism 4 stop at the lowermost position.

Here, the user first inserts the left and right calves between the massage member 5 and the pressing member 6 of the vertical massage mechanism 4 , and inserts the left and right feet between the left and right massage members 5 of the horizontal massage mechanism 3 .

In this state, when the operation switch 33 is turned ON, the drive motor 11 starts to operate, and in the vertical massage mechanism 4, the massage member 30 presses the side of the calf, and the pressing member 31 presses the calf On the back of the belly, at these front and rear pressing positions, a pressing massage that moves upwards or downwards is applied at the same time.

Moreover, in the horizontal massage mechanism 3, the rotation shaft 10 starts to rotate normally by the operation|movement of the drive motor 11. When the rotating shaft 10 rotates in the forward direction, the one-way clutch mechanism 14 is in a power transmission state, the rotational driving force of the rotating shaft 10 is transmitted to the inclined protrusion 13, and the rotating shaft 10 and the inclined protrusion 13 are integrated in the same direction. to rotate.

Accordingly, in the first drive mechanism 7, the pair of left and right massage members 5 and 5 are swung left and right via the conversion portion to repeatedly form the released state and the pinched state, and massage the feet from the left and right sides. . And the pressing member 6 (1st massage member 20 - 3rd massage member 22) is driven by the 2nd drive mechanism 8 at the same time, and press massage is given to the sole of a foot.

In this case, the rotating shaft 10 is reversed by the program of the automatic operation mode or manually. In particular, the proximity state of the massage member 5 is detected with a sensor (rotation sensor, proximity sensor, limit switch), etc., and the rotation shaft 10 is switched from the forward rotation drive to the reverse rotation drive at the timing of the foot grip state. drive.

As a result, the one-way clutch mechanism 14 (especially the one-way power transmission portion 40 ) is in a power non-transmission state, and the rotational driving force of the rotating shaft 10 is not transmitted to the inclined projection portion 13 , and the pair of left and right massage members 5 , 5 is to stop while maintaining the pinched state of the foot. However, the pressing member 6 (1st massaging member 20 to 3rd massaging member 22) is driven by the 2nd drive mechanism 8, and presses and massages the sole of the foot continuously in this state.

At this time, by the action of the braking portion 50 installed in the one-way clutch mechanism 14, the massage members 5 and 5 can be maintained in a close state (a state of being held in the foot), and the The reaction force of the massaging member 5 can be reliably suppressed from moving in the direction of separation.

In this way, by reversing the rotating shaft 10 and utilizing the operation of the one-way clutch mechanism 14 (non-power transmission operation), the pair of left and right massage members 5 and 5 can be held in a pinched state. By continuously driving the pressing member 6 (ie, the first massage member 20 to the third massage member 22 ) while maintaining the clamped state, the feet embedded between the pair of left and right massage members 5 and 5 will not be affected. Since the pressing member 6 is pressed and released upward, the pressing member 6 can be reliably and sufficiently received.

That is, by using the massage machine 1 for lower limbs, it becomes possible to perform an effective massage operation on the foot using the pair of left and right massage members 5 and 5 and the pressing member 6 .

However, the embodiment disclosed in this specification should be considered as an illustration rather than a limitation in every respect. The scope of the present invention is not based on the above-mentioned description, but is represented by the content of the scope of the patent application, and all changes that are equivalent to the scope of the patent application and within the scope should be included in the scope of the present invention.

For example, the vertical massage mechanism 4 and the horizontal massage mechanism 3 may always keep synchronizing operation, or only one of them may operate independently. These action forms can be appropriately selected according to the user's expectations.
