Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lower limb massager and a chair-type massager using the massager.

[0002]

2. Description of the Related Art Conventionally, as a chair-type massage device capable of massaging not only the back and buttocks of the human body, but also the lower limbs (particularly the part from the knee to the vicinity of the ankle).
For example, there is one disclosed in Japanese Patent No. 3012780, and this massage device includes a seat portion that supports a buttocks of a human body from below, and a backrest that is provided at a rear end portion of the seat portion and has a massage mechanism inside. And a footrest connected to the front end of the seat and having a massage function for the lower limbs.

Such a footrest is provided with a pair of left and right treatment recesses capable of accommodating the lower limb between the left and right side walls and the intermediate wall. The inner side surfaces of both side walls, both side surfaces of the intermediate wall, and the bottom surface of the treatment recess. An airbag is provided in each of and. Therefore, in the conventional footrest, by inflating and contracting each airbag by the air supply / exhaust device, both lower limbs fitted in each treatment recess can be simultaneously massaged. In the case of the airbag used for the above footrest, the bulge in the central part is usually the largest and the bulge becomes smaller toward both ends, so sufficient pressing force can be obtained only in a narrow range in the longitudinal direction of the lower limbs. However, there is a drawback in that the user must move his / her lower limb along the treatment recess to obtain the desired massage effect.

[0004]

Therefore, as shown in, for example, Japanese Patent Application Laid-Open No. 11-347082, a plurality of airbags are arranged side by side along the longitudinal direction of each treatment recess.
A footrest has been proposed in which air is supplied to and discharged from the plurality of airbags simultaneously or sequentially so that the lower limbs can be effectively massaged over a wide range in the longitudinal direction. However, in such a massage machine, it is necessary to install a plurality of airbags (massage members) in parallel on the left and right sides of one treatment recess along the longitudinal direction of the recess. It has the drawback of being expensive.

Further, in the case of an air bag type massage machine, an air supply and discharge device including a compressor, an air pipe, a solenoid valve and a control means for the valve is required, so that the device is originally large and expensive. However, in order to inflate and deflate a plurality of airbags simultaneously or sequentially, the program of the control means of the air supply / exhaust device becomes complicated, which further increases the manufacturing cost. Become. On the other hand, it is conceivable to employ a mechanism for moving both wall portions themselves constituting the treatment recess toward and away from the lower limb as means for eliminating the fundamental drawbacks inherent in the airbag type massage machine.

However, when both walls constituting the treatment recess are simply moved in parallel to move toward and away from the lower limb, both side walls press only the thick portion of the lower limb (for example, the calf) and the thin portion of the lower limb. It is not possible to properly massage (eg, near the ankle). In addition, it is not possible to perform a complicated massage motion such as massaging or massaging of the lower limb simply by translating both the wall parts. In view of such a situation, the present invention enables a wide range and appropriate massaging of the lower limbs by enabling the lower limbs to be pressed in a wide range without arranging a plurality of massage members side by side in the length direction of the lower limbs. Aim to get cheaper.

[0007]

In order to achieve the above-mentioned object, the present invention takes the following technical means. That is,
The massager for lower limbs of the present invention is arranged so as to face each other in such a state that one lower limb is sandwiched between them, and a pair of left and right lateral massage members and a lower limb made of a plate material long in the length direction of the lower limb. And a pair of left and right lateral massage members, which are disposed between the pair of left and right lateral massage members so as to support the back massager and have a bottom massage member made of a plate material long in the length direction of its lower limbs. A first drive means for moving the lateral massage members toward and away from each other in a state where the longitudinal directions are inclined in opposite directions, and changing the degree of inclination of the respective lateral massage members in the longitudinal direction of the lower limbs with respect to the longitudinal direction; And a second drive means for reciprocating the bottom massage member in a direction facing the lower limb.

In this case, when the first driving means is operated with one lower limb being sandwiched between the pair of left and right lateral massage members, the respective lateral massage members are inclined with their longitudinal directions being opposite to each other. They approach and move away, and massage the lower limbs sandwiched between them. In the present invention, the lateral massage member not only moves in parallel, but the degree of inclination in the longitudinal direction of the lateral massage member with respect to the length direction of the lower limb changes when approaching and separating the lateral massage member. Appropriately press each part with different thickness across the length. Therefore, even if a plurality of lateral massage members are not arranged in parallel along the length direction of the lower limb, it is possible to appropriately massage a wide range of portion extending in the length direction of the lower limb.

Further, since the degree of inclination in the longitudinal direction of each lateral massaging member with respect to the length direction of the lower limb changes when each lateral massaging member approaches and separates, a complicated massage such as massaging or massaging in the longitudinal direction of the lower limb is performed. You will be able to exercise. Further, when the second drive means is actuated, the bottom massage member reciprocates in a direction facing the lower limb to press the lower limb, and at this time, the bottom massage member is formed by a plate material long in the length direction of the lower limb. Since it has been, you will be able to massage a wide range of parts over its length.

In the above-mentioned present invention, when the first driving means causes the other longitudinal end portions of the pair of left and right lateral massage members to approach each other, the other end portions in the same direction move away from each other and the longitudinal direction end portions move away from each other. By driving the pair of left and right lateral massage members so that the other end portions in the direction come close to each other, the treatment portions distant in the length direction of the lower limb by the longitudinal end portions of the pair of left and right lateral massage members are provided at different timings. The massage can be performed alternately and the massage effect on the lower limbs can be improved. Further, when the pair of left and right lateral massaging members are moved toward and away from each other by the first driving means, if the degree of inclination of the lateral massaging members with respect to the thickness direction of the lower limb is changed, Even in the thickness direction, complicated massage motions such as raising or lowering the lower limbs can be performed. Further, in this case, by simultaneously operating the bottom massage members, it is possible to further enhance the effect of kneading in the thickness direction of the lower limbs.

More specifically, the first drive means for carrying out the above-mentioned action is, more specifically, a rotation which penetrates each lateral massaging member in the plate thickness direction so as to be rotatable relative to the pair of left and right lateral massaging members. Shafts, a pair of left and right cam members fixed to the axially intermediate portion of the rotary shaft, and contacting cam surfaces inclined with respect to the rotary shaft to the respective lateral massage members, and the pair of left and right lateral massagers It is possible to employ a guide member that restricts the member from rotating along with the rotary shaft while allowing the member to move in the axial direction of the rotary shaft.

Further, in the present invention, if the pair of left and right lateral massaging members are composed of leaf springs that are elastically deformable in the plate thickness direction, the lateral massaging members press the lower limbs too strongly, and the user feels pain. Can be prevented. The second driving means may be configured to move the bottom massage member in parallel to the direction opposite to the lower limb, but preferably, the inclination of the bottom massage member with respect to the longitudinal direction of the lower limb in the longitudinal direction. It is recommended that the bottom massage member be configured to reciprocate in a direction facing the lower limbs while changing the degree. This makes it possible to appropriately press the portions of the lower limbs having different thicknesses in the length direction.

Further, the second drive means is the rotary shaft which constitutes the first drive means, and is fixed to the rotary shaft. And a cam member forming a cam surface whose distance changes in the circumferential direction. Accordingly, the bottom massage member can reciprocate with a simple structure of the rotating shaft and the cam member, and the rotating shafts of the first and second driving means are shared, so that the number of parts can be reduced. In addition to contributing to simplification and compactness of the structure.

Further, the bottom massage member has a structure in which one longitudinal end thereof is in contact with the cam member and the other longitudinal end thereof is supported by a supporting member which is elastically deformable in the thickness direction of the lower limb. can do. As a result, the bottom massage member reciprocally swings on one end side with the other end side supported by the support member as a fulcrum, and the bottom massage member with respect to the longitudinal direction of the lower limb in the longitudinal direction as described above. A configuration that reciprocates while changing the degree of inclination can be easily realized. Furthermore, the support member enables the lower limb to be elastically and softly supported.

In the present invention, the two rubbing means are arranged side by side so that the treatment recesses of the lower limb formed between the respective lateral massaging members and the bottom massaging member of the same means are oriented in the same direction. In this case, the pair of lower limbs can be simultaneously massaged by the two massaging means. In this case, if the drive motor for rotating the rotary shaft is arranged between the two rubbing means, the widthwise dimension of the massage machine can be made compact. The massager for lower limbs described above can be used as a single massager that is placed on the floor or bed and used, or can be used as a footrest of a chair-type massage device.

That is, the chair-type massage device of the present invention is provided in the seat portion for supporting the buttocks of the human body from below, the backrest portion connected to the rear end portion of the seat portion, and the front portion of the seat portion. And a footrest having the massager for the lower limbs. The footrest may be detachably or integrally connected to the front end portion of the seat portion, or may be arranged in a state separated from the front end portion of the seat portion.

The lower limb massaging machine 1 of the present embodiment approaches the lateral massaging members 7, 7 so that the degree of inclination of the lateral massaging members 7, 7 with respect to the longitudinal direction of the lower limb 6 changes. First drive means 14 for separating
And second drive means 3 for reciprocating the bottom massage member 12 in a direction facing the lower limb 6 (vertical direction in FIG. 2).
4 and. The first drive means 14 includes the rotary shaft 4, a pair of left and right cam members 15 and 15 fixed to an axially intermediate portion of the rotary shaft 4, and lateral massage members 7 and 7.
A guide member 16 for restricting rotation of the rotary shaft 4 with the rotary shaft 4 while allowing the same to move in the axial direction of the rotary shaft 4.
16 are provided.

As shown in FIGS. 1 and 2, the rotary shaft 4 is
In order to be rotatable relative to each lateral massaging member 7, 7, a portion of each lateral massaging member 7, 7 that is closer to the rear part (upper side in FIG. 1) and closer to the lower side in the width direction is penetrated in the plate thickness direction. The cam members 15 and 15 are provided in this penetrating portion. As shown in FIG. 3, the cam member 15 is sandwiched between a pair of front and back sandwiching plates 17 and 18 formed in a shape in which a columnar body is obliquely cut with respect to its axis, and the sandwiching plates 17 and 18. A center plate 19 in the shape of a short cylinder, and these plates 17 to 19 are fixed screws 2 that penetrate them along the axial direction of the rotary shaft 4.
It is integrated by 0.

The sandwiching plates 17 and 18 are fixed so as not to move in the axial direction or the rotational direction with respect to the rotating shaft 4 by a key connection and a retaining ring or a rotation stopping pin. On the other hand, the central plate 19 is fixed to both the plates 17 and 18 in a state where the inclined surfaces of the sandwiching plates 18 and 19 are in contact with the front and back surfaces thereof. Therefore, the central plate 19 is arranged with its axis inclined with respect to the rotating shaft 4, and the cam surface 2 inclined with respect to the rotating shaft 4.
1 is provided on the outer peripheral portion. The central plate 19 is slidably fitted into the boss portion 22 of the lateral massaging member 7, and at this time, the cam surface 21 of the central plate 19 contacts the end surface of the boss portion 22. For this reason,
The lateral massage member 7 is rotatably connected to the rotary shaft 4 in a state of being inclined with respect to the axial direction of the rotary shaft 4.

As shown in FIG. 1 and FIG. 2, the inclination directions of the left and right cam members 15, 15 constituting one rubbing means 8 with respect to the rotation shaft 4 are set to be opposite to each other. , A pair of left and right lateral massage members 7, 7
Are designed to approach and separate from each other with their longitudinal directions inclined in opposite directions. The guide member 16 includes a guide pin 23 projecting downward from the lower edge rear side of the lateral massage member 7, and a concave guide rail 24 with which the guide pin 23 engages. As shown in FIG. 2, the guide rail 24 extends directly below the rotary shaft 4 in the base body 2D in the same direction as the rotary shaft 4, and the projecting end of the guide pin 23 is axially ( It is guided so that it can move freely in the left-right direction (FIG. 2) and cannot move in the direction orthogonal to its axial direction.

Therefore, each of the lateral massaging members 7, 7 is
The guide pin 23 provided on the lower edge of the rotary shaft 4 restricts the rotation of the rotary shaft 4 while the rotary shaft 4 is allowed to move in the axial direction. On the other hand, as shown in FIG. 1, the rotary shaft 4 is penetrated through a pair of left and right lateral massaging members 7, 7, and each lateral massaging member 7 is formed by the inclined cam surface 21 of the cam member 15 provided in this penetrating portion. , 7 are moved toward and away from each other, the lateral massage members 7, 7 have the same lengthwise one end as the other ends move away from each other and the same lengthwise endwise move as the other ends move away from each other. The other ends in the direction come close to each other.

Further, a pair of left and right lateral massaging members 7, 7
Is restricted by the guide pin 23 from rotating with respect to the rotary shaft 4, and is driven by the inclined cam surface 21 of the cam member 15 in this state, so that when these lateral massaging members 7, 7 approach and separate from each other. In addition, the degree of inclination of the lateral massage member 7 with respect to the longitudinal direction of the lower limb 6 in the longitudinal direction (vertical direction in FIG. 1) sequentially changes, and the width direction of the lateral massage member 7 in the thickness direction of the lower limb 6 ( Figure 2
The upper and lower directions of the inclination are also sequentially changed.

On the other hand, the lateral massage member 7 of this embodiment.
Is composed of a plate spring made of plastic that is elastically deformable in the plate thickness direction. This prevents the lateral massage member 7 from pressing the lower limb 6 too strongly and causing the user to feel pain. ing. Further, as shown in FIG. 1, since the rotary shaft 4 penetrates the lateral massage members 7, 7 toward the rear part, the lateral massage member 7 is located on the rear side (ankle side) of the rotary shaft 4. L1 is short, and the front (calf side) portion L2 is long.

Therefore, the separation distance between the pair of left and right lateral massaging members 7, 7 on the calf side is larger than that on the ankle side, and a calf portion thicker than the ankle can be suitably fitted between them, and conversely, the ankle. Since the approaching distance between the pair of left and right lateral massaging members 7, 7 is smaller on the calf side than on the side, the calf fitted between them can be deeply pressed. However, on the calf side, since the length L2 of the lateral massaging members 7, 7 is secured long, and it is easy for flexure (elastic deformation) to occur in the plate thickness direction, even if the calf is deeply pressed, the flexure causes the user to flex. It is prevented that the person presses excessively so as to feel pain.

On the ankle side, the approaching distance of the lateral massaging members 7, 7 is larger than that on the calf side, but the length L2 of the lateral massaging members 7, 7 is shorter on the ankle side so that the bending is suppressed. Therefore, the pressing force can be increased correspondingly, and thereby a substantially uniform pressing force can be obtained over the length direction of the lower limb. As shown in FIG. 4, the second drive means 34 includes the rotary shaft 4 and a cam surface which is fixed in an eccentric state with respect to the rotary shaft 4 and is formed on the outer peripheral portion of the rotary shaft 4 on the bottom massage member 12. And a cam member 35 that is in contact therewith.

The cam member 35 is formed in a disk shape, and the rotary shaft 4 penetrates at a position eccentric from the center thereof so as to rotate integrally with the rotary shaft 4.
Therefore, the cam surface (outer peripheral surface) of the cam member 35 is such that the distance from the rotating shaft 4 changes in the circumferential direction. The bottom massage member 12 is adapted to abut on the cam surface of the cam member 35 via a ring-shaped connecting member 37 fixed to the lower surface on the rear side thereof. Is rotatably fitted in the.

The lower surface of the front portion of the bottom massage member 12 is connected to the upper end of a support member 36 which stands upright from the base body 2D. The support member 36 of the present embodiment is composed of an elastically deformable coil spring. Drive motor 5
When the rotary shaft 4 is rotated in the direction of arrow C in FIG. 4 by the operation of, the cam member 35 rotates back and forth and up and down around the shaft center of the rotary shaft 4. The rear side of the bottom massage member 12 moves in the front-rear direction (longitudinal direction) as shown by the arrows D1 and D2 in accordance with the rotation of the cam member 35, and moves upward and downward with the support member 36 on the front side as a fulcrum. A reciprocating swing motion is made in the direction (opposite the lower limb 6).

Further, the bottom massage member 12 has a swinging range set so that when the rear side is the lowest, it is slightly lower than the front side, and when the rear side is the highest, it is higher than the front side. The support member 36 is configured to absorb the longitudinal movement of the front side and the change of the inclination accompanying the longitudinal movement of the rear side of the bottom massage member 12 by elastically deforming. Therefore, the bottom massage member 1
2 reciprocates in the direction facing the lower limb while changing the degree of inclination of the lower limb in the longitudinal direction,
The lower limb 6 is pressed from the lower side and massaged.

Further, since the bottom massage member 12 swings up and down on the rear side with the front side as a fulcrum, it swings up and down largely on the thin ankle side, and toward the calf side thicker than the ankle side. The vertical swing amount becomes smaller as it goes, and it is possible to massage with a substantially uniform pressing force over the length direction of the lower limb. Further, since the bottom massage member 12 also moves back and forth together with the vertical swing, complicated massage such as rubbing up or down in the length direction of the lower limb 6 is also possible.

Pressing projections 43a made of small rollers are provided on the front and rear parts of the upper surface of the bottom massage member 12, and pressing projections 43 made of large rollers are provided in the middle part of the front and rear.
b is provided. In addition, between the small roller 43a and the large roller 43b on the rear side, the pressing protrusion 4 composed of a small protrusion is formed.
A plurality of 3c are provided. These pressing protrusions 43a-4
3c acts as an acupressure on the lower limb 6, and the pressing protrusions 43a and 43b composed of large and small rollers are provided so as to rotate in the front-rear direction, and the rotation causes the bottom massage member to rotate. The friction with respect to the lower limb 6 due to the forward and backward movement of 12 is reduced.

Next, the lower limb massager 1 of this embodiment
The operation (particularly, the operation of the lateral massage member 7) will be described. First, the lower leg 6 of the person
To massage the person's lower limbs 6, the respective rubbing means 8,
It is sandwiched between a pair of left and right lateral massaging members 7, 7 (inside the treatment recess 13), and the drive motor 5 is operated to drive the lateral massaging members 7, 7 by the first and second driving means 14, 34. And the bottom massage member 12 are reciprocated up and down. At this time, the lateral massaging members 7, 7 approach and separate with their longitudinal directions inclined in opposite directions, and massage the lower limb 6 sandwiched between them from the left and right. Massage from below.

FIGS. 5 to 8 show the manner of massaging movement by the lateral massaging members 7, 7 in that case. Of these, FIGS. 5 and 6 show the time of each kneading means 8, 8. FIG. 9 is a plan view showing a movement accompanying a change, and FIGS.
FIG. 7 is a front view corresponding to FIGS. 5 and 6. That is,
5B shows a state in which the rotary shaft 4 has made a quarter turn from the state of FIG. 5A, and FIG. 6C shows a state in which the rotary shaft 4 has a quarter of the state of FIG. 5A. 6 shows the state of two rotations of FIG.
5D shows a state in which the rotary shaft 4 has rotated three-quarters from the state shown in FIG. Further, FIGS. 7A, 7B and 8C, 8D are front views corresponding to FIGS. 5A, 5B and 6C, 6D, respectively.

First, as shown in FIG. 5 (a), one end side (rear end side) of the widthwise upper end edge 7A of each lateral massage member 7, 7 is closest to the other end side (front end side). Are inclined in opposite directions with respect to the rotating shaft 4 so as to be most separated from each other, and as shown in FIG. 7A, one end edge 7B in the longitudinal direction of each of the lateral massaging members 7, 7 and the other end. Edge 7C
(The plate surfaces of the lateral massage members 7, 7) are in a state of standing upright substantially vertically. When the rotary shaft 4 is rotated a quarter turn in the direction a in the figure from the state of FIGS. 5 (a) and 7 (a), as shown in FIG. 5 (b), the upper edge of each of the lateral massaging members 7, 7 is 7A approach each other, each lateral massage member 7,
The longitudinal direction of 7 is substantially perpendicular to the rotation axis 4, and
As shown in (b), the longitudinal one end edge 7B and the other end edge 7C of each of the lateral massage members 7, 7 are inclined so that their upper end sides are closest to each other.

When the rotary shaft 4 is further rotated a quarter turn from the state shown in FIGS. 5 (b) and 7 (b), as shown in FIG. 6 (c), the lateral massaging members 7, 7 are arranged in the width direction. Upper edge 7A
Are inclined in opposite directions with respect to the rotating shaft 4 so that one end side (rear end side) thereof is most separated and the other end side (front end side) thereof is closest to each other, as shown in FIG. As shown, one end edge 7B and the other end edge 7C (the plate surface of the horizontal massage members 7, 7) in the longitudinal direction of each horizontal massage member 7, 7 are substantially vertically upright. In addition, FIG. 6 (c) and FIG.
When the rotary shaft 4 further rotates a quarter turn from the state (c), as shown in FIG. 6D, the width-direction upper end edges 7A of the lateral massage members 7, 7 are separated from each other, and the lateral massage members 7 are separated. , 7 become substantially perpendicular to the rotation axis 4, and as shown in FIG. 8 (d), one end edge 7B and the other end edge 7C in the longitudinal direction of each lateral massaging member 7, 7 are Tilt to the farthest position.

When the rotary shaft 4 is further rotated a quarter turn from the state shown in FIGS. 6 (d) and 8 (d), the lateral massaging members 7 and 7 are returned to the original positions shown in FIGS. 5 (a) and 7 (). It returns to the state of a). Thus, according to the lower limb massaging machine 1 of the present embodiment, the pair of left and right lateral massaging members 7, 7 formed in a plate shape that is long in the length direction of the lower limb 6 simply translates toward the lower limb 6. In addition, since the degree of inclination of the lower limb 6 in the longitudinal direction with respect to the length direction changes when approaching and separating the lateral limb 6, the lateral massaging member 7 appropriately adjusts each portion having a different thickness across the lower limb 6 in the longitudinal direction. Press.

Therefore, even if a plurality of lateral massaging members are not arranged side by side along the length direction of the lower limb 6, a single lateral massaging member 7 can appropriately cover a wide range of the lower limb 6 in the longitudinal direction. You can massage. Further, when the lateral massaging members 7, 7 approach and separate from each other, the degree of inclination of the lateral massaging members 7, 7 in the longitudinal direction with respect to the longitudinal direction of the lower limb 6 changes. Can perform complex massage exercises such as massaging. Also, when the longitudinal direction one ends of the pair of left and right lateral massaging members 7 approach each other, the other ends in the same direction move away from each other, and when the longitudinal direction one ends move away from each other, the other ends in the same direction approach each other. (Fig. 5
(A) and FIG. 6 (c)), it is possible to alternately massage the treatment portions separated in the lengthwise direction of the lower limb 6 by the longitudinal end portions of the pair of left and right lateral massage members 7, 7 at different timings. Also in this respect, the massage effect on the lower limbs 6 can be improved.

Furthermore, when both lateral massaging members 7, 7 approach and separate from each other, the degree of inclination of the lower limb 6 in the width (vertical) direction with respect to the thickness direction also changes, so the thickness of the lower limb 6 Also in the direction, a complicated massage motion such as massaging or massaging of the lower limb 6 can be performed. On the other hand, as shown in FIG. 7 (b), the bottom massage member 12 descends downward when the upper edge 7A of the lateral massage members 7, 7 approaches each other (when the lower limb 6 is massaged down), and as shown in FIG. As shown in d), the lateral massage member 7,
When the upper edges 7A of 7 move away from each other (when the lower limbs 6 are rubbed up), the upper edges 7A are raised.

Therefore, when the lower limb 6 is massaged by the lateral massaging members 7, 7, the bottom massaging member 1
2 is lowered so that the lower limb 6 is not excessively pressed, and the lateral massaging members 7, 7 are used to lower the lower limb 6.
When kneading is done, by raising the bottom massage member 12, the kneading action is further enhanced.
However, the bottom massage member 12 raises the bottom massage member 12 strongly when the lower limb 6 is massaged by the lateral massage members 7 and 7, and massages the lower limb 6 by the horizontal massage members 7 and 7 in reverse timing. It is also possible to exercise by lowering the bottom massage member 12 when rubbing it up.

The lower limb massager 1 described above is
