 [Formation of the Invention]  

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

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

The lower limb massage machine 1 of the present embodiment is configured such that the lower limbs on the left and right sides of the user are used as the massage target (the treatment portion), and the both the foot and the calf that constitute the lower limb are simultaneously massaged or linearly Mobile compression massage (shiatsu massage).

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

The lower limb massage machine 1 of the present embodiment has a casing 2 having a square shape in a front view and a boot type (L-shaped) in a side view. On the front surface of the outer casing 2, a pair of left and right treatment recesses 9 that are open toward the front and the upper side are arranged side by side and arranged side by side. These left and right treatment recesses 9 are provided with an inner lining material which is elastic and flexible and has appropriate air permeability.

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

The term "horizontal" and "vertical" of the horizontal massaging mechanism 3 or the vertical massaging mechanism 4 is merely an expedient description in the present specification, and is not limited to the state of use of the lower limb massager 1.

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

As shown in FIG. 2 to FIG. 5 and the like, the horizontal massaging mechanism 3 has a pair of left and right massage members 5 and 5 which are arranged side by side in the left-right direction so as to be insertable into the foot; the pressing member 6 is provided on the left and right sides. The pair of massage members 5 and 5 are disposed between each other; the first drive mechanism 7 causes the pair of left and right massage members 5 and 5 to approach each other, and the second drive mechanism 8 operates the pressing member 6.

The massage members 5 and 5 are a pair of left and right pairs, and the combination is provided in total in two groups corresponding to the left and right treatment recesses 9 of the outer casing 2. The massage member 5 is formed into a erected plate shape by a material having elasticity in the thickness direction, and the inner surface of the massage member 5 facing each other is provided with a cushioning material or a covering material which can give a soft touch feeling to the foot.

The first drive mechanism 7 of the horizontal massage mechanism 3 reciprocates the pair of left and right massage members 5 and 5 in a holding position (see FIG. 4) for holding the foot portion interposed therebetween, and a release position. (Refer to Fig. 3), and the massage action is given to the foot by means of the method. The first drive mechanism 7 drives the two sets of massage members 5 and 5 simultaneously.

The first drive mechanism 7 includes a single rotating shaft 10 that is provided in a direction (left-right direction) that passes through the massage members 5 and 5, a drive motor 11 (electric motor) that rotationally drives the rotary shaft 10, and a conversion unit that will The rotational driving force of the rotating shaft 10 is converted into a massaging action of the massaging member 5.

The drive motor 11 is switchable between the forward rotation drive and the reverse rotation drive, and transmits the rotational driving force to the rotary shaft 10 via a speed reduction portion in which the worm and the worm wheel meshing with the worm are provided.

The conversion portion has an inclined convex portion 13 that is provided at a portion where the rotating shaft 10 penetrates the massage member 5, and the rotating shaft 10 penetrates the center portion thereof, and the outer peripheral edge has a cam groove that is inclined to the rotating shaft 10.

In the case of this embodiment, the one-way clutch mechanism 14 is provided between the inclined projection 13 and the rotating shaft 10. Therefore, when the drive motor 11 is driven in the normal rotation and the rotary shaft 10 is in the forward rotation, the rotational driving force of the rotary shaft 10 is transmitted to the inclined projection portion 13, and the rotary shaft 10 and the inclined projection portion 13 are integrally formed in the same direction. Rotate. On the other hand, when the drive motor 11 is reversely driven and the rotary shaft 10 is reversed, the inclined projection 13 is in an idling state with respect to the rotary shaft 10, and the rotational drive force of the rotary shaft 10 is not transmitted to the inclined projection portion 13.

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

The outer peripheral edge of the inclined projection 13 is fitted into the annular fitting portion 15 provided at the proximal end of the massage member 5 via a bearing, and the massage member 5 is held in a state in which the rotary shaft 10 is relatively rotatable.

In addition, the conversion portion has a structure in which the restriction protrusion 16 that protrudes downward from the massage member 5 is engaged with the horizontally long hole 17 that is long in the left-right direction provided in the base frame portion 2a of the support frame. Since the restricting projection 16 is engaged with the horizontally long hole 17, and the restricting projection 16 is slid in the laterally long hole 17, the massage member 5 does not rotate with the inclined convex portion 13 (driven rotation). That is, when the rotary shaft 10 rotates, the inclined projection portion 13 swings around the rotary shaft 10 in the left-right direction corresponding to the tilt component, and only the swing component at this time is transmitted to the massage member 5.

The inclination direction in which the inclined projection 13 is inclined with respect to the rotary shaft 10 is set to be relatively reversed between the massage members 5 and 5. Therefore, when the pair of left and right massage members 5 and 5 approach each other, a so-called split swing operation is performed. When the pair of right and left massage members 5 and 5 approach each other, the foot placed between the massage members 5 and 5 is held, and the massage operation is performed from the right and left.

When the pair of left and right massage members 5 and 5 are separated from each other, the foot placed between the massage members 5 and 5 is released. By continuously rotating the rotary shaft 10, the massage members 5, 5 can alternately perform the above-described holding and releasing operations alternately while performing an undulating swing in a state limited to a predetermined angular range.

The above-described operation is an operation that occurs when the rotary shaft 10 is rotated forward. That is, when the rotating shaft 10 rotates forward, the rotational driving force of the rotating shaft 10 is transmitted to the inclined convex portion 13 by the one-way clutch mechanism 14, and the rotating shaft 10 and the inclined convex portion 13 integrally rotate in the same direction. The massage member 5 is driven by the swing.

On the other hand, when the rotary shaft 10 is reversed, the one-way clutch mechanism 14 causes the tilting projection 13 to be idling with respect to the rotary shaft 10, and the rotational driving force of the rotary shaft 10 is not transmitted to the inclined projection portion 13. Therefore, the massage member 5 is stopped while maintaining the grip state of the foot or the release state of the foot, but the pressing member 6 to be described later is driven.

On the other hand, as shown in FIG. 2 or FIG. 5, the pressing member 6 that presses and massages the sole of the foot has a rotating rotor 20 that is integrally rotatable with respect to the rotating shaft 10 provided in the first driving mechanism 7; The projections are disposed on the outer circumferential surface of the rotary rotor 20 so as to be spaced apart from each other in the circumferential direction and the axial direction by a predetermined interval.

The second drive mechanism 8 that drives the pressing member 6 presses the rotary rotor 20 and the rotary shaft 10 integrally, and presses the foot portion that is fitted between the pair of right and left massage members 5 and 5 to press upward. The foot (forefoot, arch, heel) gives the massage action.

When the rotary rotor 20 is rotated by the rotation of the rotary shaft 10, the plurality of projections can be moved from the rear side to the front side or vice versa from the front side to the rear side in accordance with the rotation direction of the rotary shaft 10. .

In the case of the present embodiment, the pressing member 6 that presses and massages the sole of the foot has a more complicated configuration.

The pressing member 6 of the present embodiment has a first massage member 20 that massages the center portion of the sole of the user, and has a second massage member 21 that massages the back of the sole of the user, and a third massage that massages the front of the sole of the user. When the member 22 drives the first massage member 20 to the third massage member 22 in conjunction with each other, a massage operation on the sole of the foot can be generated.

The first massage member 20 is the above-described rotary rotor 20 that applies a pressing massage operation to the center portion of the sole.

The first connecting piece 23 having an arm shape is formed to extend rearward from the first massage member 20 (rotary rotor), and the first connecting piece 23 is rotatably rotated in a state where the base end portion is eccentric to the rotating shaft 10 The second massage member 21 is provided at the distal end portion, and the second massage member 21 coupled to the first coupling piece 23 is oscillated by the rotational movement of the rotary shaft 10.

Further, the arm-shaped second connecting piece 24 is formed to extend forward from the first massage member 20 (rotation roller), and the second connecting piece 24 is eccentric with respect to the rotating shaft 10 at the proximal end portion. The third massage member 22 is rotatably mounted, and the third massage member 22 is provided at the distal end portion, and the third massage member 22 coupled to the second coupling piece 24 is slidably swung in the front-rear direction by the rotational movement of the rotary shaft 10.

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

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

As described above, in the massage machine for lower limbs 1 of the present embodiment, the one-way clutch mechanism 14 is provided between the inclined projection portion 13 and the rotary shaft 10.

The one-way clutch mechanism 14 is composed of a one-way power transmission unit 40 and a brake unit 50.

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

As shown in FIGS. 6 and 7, the one-direction power transmission portion 40 has a volute projection portion 42 that is fitted into the inside of the inclined projection portion 13 in a loosely fitted state. In the volute projection portion 42, the rotary shaft 10 penetrates the center portion thereof and is fixed to the rotary shaft 10 to form a mode of rotation.

The outer peripheral edge of the volute projection 42 is formed with a cam groove 43 having a spiral shape in a side view. In detail, the cam groove 43 has the largest radius at a position of 0 degree angle, and its radius is shortened as it rotates in the counterclockwise direction. Therefore, the radius is minimized until just one round of the circle (angle 360 degrees). Therefore, a steep cliff portion 44 (position restricting portion) is formed at a position of an angle of 360 degrees (in other words, an angle of 0 degrees). The cam groove 43 has a snail-like shape in a side view. In each of the massage members 5, the cliff portion 44 is formed at a predetermined position in the circumferential direction of the rotary shaft 10.

For example, the position corresponding to the pressing member 5 that is inserted into the right foot and the position corresponding to the pressing portion 5 that is inserted into the left foot of the cliff portion 44 are set to the same position in the circumferential direction of the rotating shaft 10, The left foot can be pressed as well while holding the right foot. 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 that has been thrown into the right foot and the position of the cliff portion 44 corresponding to the pressing member 5 that is inserted into the left foot are shifted by 90 degrees in the circumferential direction of the rotating shaft 10. Or 180 degrees, for example, when the right foot (left foot) is pressed, the left foot (right foot) is set to the relaxed state or the 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 lower end bottom of the positioning piece 45 is slidable on the cam groove 43 of the volute projection 42. The positioning piece 45 has a shape of a corner post and a direction in which the growth direction faces the radial direction of the volute projection 42. On the other hand, the upper end portion of the positioning piece 45 is fitted into the groove portion 46, and is slidable in the radial direction in the groove portion 46, and the groove portion 46 is provided on the inner side in the width direction of the inclined convex portion 13 (facing the snail-shaped convex portion) Side of 42), located radially outward and facing the radial direction.

When the disassembled state member shown in FIG. 7 is assembled, the snail-shaped projecting portion 42 is fitted in a loosely fitted state in a cylindrical recessed portion 47 formed on the radially inner side of the inclined projecting portion 13, and the positioning piece is formed. 45 is slid over the cam groove 43 of the volute projection 42 and the upper end portion of the positioning piece 45 is fitted into the groove portion 46 of the inclined projection portion 13.

With this configuration, when the rotating shaft 10 rotates in the normal rotation direction (the direction in which the snail-shaped projection 42 rotates in the clockwise direction when the volute projection 42 is viewed from the direction of FIG. 7), it is formed in the volute projection. The cliff portion 44 of the 42 abuts against the side surface of the lower end portion of the positioning piece 45, so that the volute projection portion 42 can rotate together with the positioning piece 45. In other words, as the rotary shaft 10 rotates in the normal direction, 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 by the groove portion 46 in which the inclined convex portion 13 is fitted, the inclined convex portion 13 also rotates in the normal rotation direction as the rotating shaft 10 rotates forward, and is further driven by the rotation. The force causes the massage member 5 to 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 projection 42 is rotated in the counterclockwise direction when the snail-shaped projection 42 is viewed from the direction of FIG. 7), the positioning piece 45 is in the volute convexity. The cam groove 43 of the outlet portion 42 slides without engaging with the cliff portion 44 formed on the volute projection portion 42. When the positioning piece 45 reaches the cliff portion 44, that is, when the angle of the volute convex portion 42 reaches the angle of 360 degrees, the positioning piece 45 moves so as to fall from the cliff portion 44.

Therefore, when the rotating shaft 10 rotates in the reverse direction, the cliff portion 44 does not abut against the side surface of the lower end portion of the positioning piece 45, and the positioning piece 45 slides only on the cam groove 43 of the volute protruding portion 42. The lobes 42 and the positioning piece 45 do not rotate together. Therefore, when the rotary shaft 10 is rotated in the reverse direction, the rotational driving force is not transmitted to the positioning piece 45, and the inclined convex portion 13 is in a non-rotating state. Therefore, the massage member 5 does not perform the swinging motion, but is in a stopped state.

By the one-way power transmission unit 40 described above, the swinging state and the stopped state of the massaging member 5 can be switched.

However, when the massage member 5 is in the stopped state, in other words, the rotating shaft 10 is reversed, and the lower end portion of the positioning piece 45 is slid on the cam groove 43 of the volute protruding portion 42, the load is applied to the massage member 5. When the lower end portion of the positioning piece 45 is arbitrarily moved in the counterclockwise direction on the cam groove 43 of the volute convex portion 42 by the inclined projection portion 13, the massage member 5 is inadvertently operated.

For example, even in a state in which the massage members 5, 5 are close to each other (a state in which the foot is broken), the rotation shaft 10 is switched from the forward rotation to the reverse rotation, so that the massage member 5 is stopped, and the reaction of the foot being broken is also caused. A force is applied to the massage member 5 to move the massage member 5 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 does not rotate the inclined projection portion 13 in the reverse rotation direction.

As shown in Fig. 8, the brake portion 50 has a brake inner ring portion 51 that is attached to the outer side in the width direction of the inclined projection portion 13 by using a mounting ring 55, and a brake outer ring portion 52 that is attached to surround the brake inner ring portion 51. The outer peripheral portion is fixed to the outer 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 case of the present embodiment) triangular projections 53 having a right-angled triangular shape in the side view are formed in the outer circumferential direction of the brake inner ring portion 51. The distance (gap) from the inner peripheral surface of the brake outer ring portion 52 in the vicinity of the apex of the triangular convex portion 53 is extremely narrow, and the distance from the inner peripheral surface of the brake outer ring portion 52 in the vicinity of the concave portion of the triangular convex portion 53 (Gap) becomes wider.

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

When the rotating shaft 10 is rotated in the normal rotation direction (the direction in which the brake inner ring portion 51 is rotated in the counterclockwise direction when the brake inner ring portion 51 is viewed from the direction of FIG. 8) in accordance with the braking portion 50 having the above configuration, the gap member 54 is rotated. The recessed portion formed between the triangular convex portions 53 is in a state in which the brake inner ring portion 51 and the brake outer ring portion 52 are completely disconnected. Therefore, the brake inner ring portion 51 and the brake outer ring portion 52 are in a non-connected state, and the function as the braking portion 50 cannot be generated. Therefore, the rotation of the inclined convex portion 13 is not hindered, and the massaging member 5 can be surely oscillated and driven.

Conversely, when the rotating shaft 10 rotates in the reverse direction (the direction in which the brake inner ring portion 51 rotates clockwise when the brake inner ring portion 51 is viewed from the direction of FIG. 8), the gap member 54 climbs up the triangular convex portion 53. It is inclined and reaches the vicinity of the apex of the triangular convex portion 53. The gap member 54 reaching the vicinity of the apex of the triangular convex portion 53 is engaged with the gap between the triangular convex portion 53 (in other words, the brake inner ring portion 51) and the brake outer ring portion 52, and the brake inner ring portion 51 and the brake outer ring portion 52 are integrally rotated. .

When this state is reached, the brake inner ring portion 51 is connected to the brake outer ring portion 52 that is coupled to the fixed side (for example, the outer casing), so that the brake inner ring portion 51 is in a non-rotating state. Therefore, the rotation of the inclined projection 13 connected to the brake inner ring portion 51 is hindered, and the movement of the massage member 5 at this position is suppressed.

By the action of the braking unit 50, even when the massage members 5 and 5 are close to each other (the state in which the foot is inserted), even if the rotating shaft 10 is switched from the forward rotation to the reverse rotation, the massage member 5 can be stopped. The reaction force of the invaded foot portion surely suppresses the movement of the massage member 5 in the separation direction.

Further, the massage machine for lower limbs 1 includes a vertical massage mechanism 4 (calf massage mechanism).

The vertical massage mechanism 4 can be of various types. In the case of the present embodiment, as shown in FIG. 1, the vertical massage mechanism 4 has a massage member 30 that presses the front outer side and the inner side of the calf; the pressing member 31 The calf is massaged from the back side, and the lifting and lowering drive unit 32 moves the massage member 30 integrally with the pressing member 31 up and down.

The massage member 30 and the pressing member 31 are grouped together, and two sets are collectively provided in such a manner that the combination corresponds to the treatment recesses 9 on the right and left sides of the outer casing 2. By the massage member 30 and the pressing member 31 being integrally moved up and down, the massage can be effectively applied to the front and rear of the calf.

Next, an operation state of the lower limb massage machine 1 (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 operation switch 33, the pair of right and left massage members 5 of the horizontal massage mechanism 3 are released. Further, the massage member 5 and the pressing member 6 of the vertical massaging mechanism 4 are stopped at the lowest position.

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

When the operation operation switch 33 is turned on in this state, 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 lower leg. At the back of the belly, the pressing massage is applied to the front and rear pressing positions simultaneously with the upward or downward movement.

Further, in the horizontal massaging mechanism 3, the rotation shaft 10 starts to rotate in the forward direction by the operation of the drive motor 11. In the case where the rotary shaft 10 rotates forward, the one-way clutch mechanism 14 is in a power transmission state, and the rotational driving force of the rotary shaft 10 is transmitted to the inclined projection portion 13, and the rotary shaft 10 and the inclined projection portion 13 are integrated in the same direction. Rotate ground.

In the first drive mechanism 7, the pair of right and left massage members 5 and 5 are swung left and right by the conversion unit to repeatedly form the release state and the grip state, and the foot is massaged from the left and right sides. . At the same time, the pressing member 6 (the first massage member 20 to the third massage member 22) is driven by the second drive mechanism 8, and the bottom of the foot is pressed and massaged.

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

Then, the one-way clutch mechanism 14 (particularly, the one-way power transmission unit 40) is in a power non-transmission state, and the rotational driving force of the rotary shaft 10 is not transmitted to the inclined convex portion 13, but the pair of right and left massage members 5, 5 is stopped while maintaining the grip of the foot. However, the pressing member 6 (the first massage member 20 to the third massage member 22) is driven by the second drive mechanism 8, and in this state, the foot is continuously pressed and massaged.

At this time, the massage members 5, 5 can be maintained in an approaching state (a state in which the foot is broken) by the action of the braking portion 50 provided in the one-way clutch mechanism 14, and by the foot from being invaded The reaction force of the massage member 5 in the direction of separation can be surely suppressed.

In this manner, by rotating the rotary shaft 10 and using the operation of the one-way clutch mechanism 14 (not transmitting the power operation), the pair of left and right massage members 5, 5 can be held in a gripped state. By driving the pressing member 6 (that is, the first massage member 20 to the third massage member 22) while being in the held state, the foot between the pair of right and left massage members 5 and 5 is not inserted. The pressing member 6 is detached upward by the pressing of the pressing member 6, and thus the pressing of the pressing member 6 can be surely and sufficiently received.

In other words, by using the massaging machine 1 for lower limbs, the pair of right and left massage members 5, 5 and the pressing member 6 can be used to perform effective massage on the foot.

However, the embodiments disclosed in the specification are to be considered as illustrative and not restrictive. The scope of the present invention is not intended to be limited by the scope of the invention, but the scope of the claims and the scope of the claims.

For example, the vertical massaging mechanism 4 and the horizontal massaging mechanism 3 may also be synchronized at all times, or only one of them may operate independently. These action patterns can be appropriately selected according to the user's expectations.
