[0002]

2. Description of the Related Art As an air massager for legs, as disclosed in Japanese Patent Laid-Open No. 10-295753 (hereinafter referred to as "Prior Art 1"), a leg rest ( The one adopted for the footrest) is known. The leg rest disclosed in the prior art document 1 is provided with left and right side wall portions on both left and right sides of the inner bottom surface of the leg rest,
Separation hills are provided in a bulging shape at the center of the leg rest in the left-right direction, and the left and right legs can be sorted and held on both sides of the separation hills. Air cells are provided in an opposed manner on the inner side surfaces of the left and right side wall portions and the left and right side surfaces of the separation hill.

The air cell expands and contracts due to air supply and discharge, and by the expansion and contraction operation of the air cell, both side surfaces of both legs can be pressed in a pinching manner. In the leg rest like the prior art document 1, there is a separation hill between both legs. This separation hill
It is necessary to provide an air cell. However, it is a hindrance when the legs are not massaged. This is because the separation hill when not massaged is located between both legs, which gives the user a feeling of restraint between the legs, which impairs a feeling of relaxation.

In recent years, chair-type massage machines tend to be used as a relax chair, and the comfort of sitting when not massaged tends to be emphasized. However, the one with the separated hills on the leg rests is contrary to the demand for emphasis on sitting comfort. On the other hand, as an air massager for legs that does not have a separation hill, Japanese Patent Publication No.
JP-A-4-13638 (hereinafter referred to as "Prior Document 2")
There is one disclosed in. The leg air massager of the prior art document 2 is also adopted in the leg rest part of the chair type massager, and left and right side walls are provided on the left and right sides of the inner bottom surface of the leg rest part, and between the left and right side walls. You can put both legs in,
Air cells are provided on the inner surfaces of the left and right side walls. However, unlike the one described in the prior art document 1, a member such as a separation hill located between both legs is not provided.

Therefore, with respect to the feeling of relaxation of the legs, the one described in the prior art document 2 is considered to be superior to the one described in the prior art document 1.

[0006]

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention
If the member located between the both legs is not provided as described above, there is a problem that the pressing by the air cells provided on the inner side surfaces of the left and right side walls cannot be effectively performed. The air cells provided on the inner surfaces of the left and right side walls laterally press the legs from the left and right outer sides to the left and right inner sides. However, since there is no member located between the legs, the legs escape in the pressing direction of the air cell, the pressing force is reduced, and effective massage cannot be performed.

On the other hand, in order to prevent the legs from escaping to the side due to the pressing by the air cell, if a separating hill as in the prior art document 1 is provided as a member located between the legs, it becomes an obstacle when not massaging. Is as described above. That is, in the prior art document 1, since there is a separation hill, it is possible to prevent the legs from escaping to the side even when pressed by the air cell, but the presence of the separation hill may impair the feeling of relaxation. On the other hand, in the prior art document 2, since there is no separation hill, a feeling of relaxation can be obtained, but since there is no separation hill, when the air cell is pressed, the legs escape laterally and effective massage cannot be performed.

In summary, the prior art 1 and the prior art 2
In any of these cases, it was not possible to effectively perform massage with air cells provided on the left and right side walls while maintaining a relaxed feeling. The present invention has been made in view of such problems, and an object of the present invention is to solve the problems of the prior art document 1.
It is to enable effective massage by air cells provided on both left and right side walls without providing an obstacle member such as a separation hill in FIG.

Then, in the leg air massager in which side air cells for pressing the side portions of both legs housed in the concave leg housing portion are provided on the inner surfaces of the both side walls, the bottom surface is supplied with air from the bottom surface. A bottom air cell that expands in a projecting shape and contracts when exhausted is provided, and the bottom air cell is designed to expand such that a portion of the bottom surface near the center in the left and right direction has a larger amount of protrusion from the bottom surface than a portion near the side wall. It is a bag body configured in.

According to this structure, since both legs are housed in one concave leg housing portion, there is no interfering member between the two legs housed in the concave leg housing portion, and a relaxed feeling can be obtained. Moreover, the bottom air cell expands so that the amount of protrusion of the portion near the center of the left and right sides of the bottom surface is greater than the amount of protrusion of the portion relative to the side wall. The center of the bottom surface on the left and right corresponds between the two legs housed in the recessed leg housing portion, so that the bottom air cell expanded from the center of the bottom surface on the left and right sides presses the legs in the direction of separating them in the left-right direction. That is, the bottom air cell expands to press the leg against the side wall.

Therefore, when the side air cells are inflated with the bottom air cells inflated, the pressing force due to the expansion of the side air cells can be received by the expansive force toward the side wall of the bottom air cells, so that the space between the two legs in the concave leg accommodating portion can be received. Even if there is no member in the leg, it is possible to prevent the legs from escaping due to the pressure due to the expansion of the side air cells, and effective massage can be performed. Also,
From another point of view, the feature of the present invention is that both legs of a user can be stored side by side in a single concave leg storage portion provided with a bottom surface and side walls standing upright from both left and right sides of the bottom surface, and air can be supplied and discharged. In the leg air massager in which the side air cells that are inflated and contracted to press the side portions of both legs housed in the concave leg housing unit are provided on the inner surfaces of the both side walls, air is supplied to the bottom surface. And a bottom surface air cell that expands in a protruding shape from the bottom surface and contracts when exhausted, and the bottom surface air cell is a pressing force in a direction that separates both legs stored in the concave leg storage portion in the left-right direction when expanded. Is provided so as to cause.

In the leg air massager equipped with, the side air cells are configured to project and expand toward the bottom surface side, and the bottom surface air cells are configured to project and expand toward the side wall side, and expand toward the bottom surface side. The legs can be sandwiched and pressed by the side air cells and the bottom air cells that expand toward the side wall.

As the bottom surface air cells, there are provided a first bottom surface air cell provided on one side of the bottom surface in the left-right direction and a second bottom surface air cell provided on the other side of the bottom surface in the left-right direction. It is preferable that the air cell and the second bottom surface air cell are configured such that a permissible expansion amount of a portion of the bottom surface near the left-right center is larger than a permissible expansion amount of a portion near the side wall. Further, it is preferable that the first bottom surface air cell and the second bottom surface air cell are formed such that the flat bag body expands in a fan shape by air supply when contracted.

Alternatively, it is preferable that the bottom air cell is formed so that the expansion amount on the left and right ends is smaller than that on the left and right central portion, and is arranged across the left and right central portion of the bottom surface. Further, it is preferable that a vibration device that generates vibration is provided on the bottom surface. Further, it is preferable that the both side walls are configured to be movable in the left-right direction, and the space between the both side walls can be adjusted. in this case,
Since the distance between both side walls is adjustable, it is easy to put the leg in the concave leg storage portion by adjusting the distance between both side walls according to the difference in the physical constitution of the user.

These side air cells 8a and 8b expand and contract when air is supplied and discharged, and expand in a protruding manner from the side wall inner surface 16 so that the outer side portions of the legs L1 and L2 accommodated in the concave leg accommodating portion 15 are disposed. Press. That is, the first side surface air cell 8a provided on the inner surface 16 of the one side wall 12a (the left side wall in FIGS. 2 and 3) expands to the other side wall 12b side in a protruding manner, and the other side wall 12b (see FIG. 2). Also, the second side surface air cell 8b provided on the inner surface 16 of the right side wall (in FIG. 3) expands in a protruding shape toward the side wall 12a.

The air cell 9 provided on the bottom surface 11a
The a and 9b (hereinafter, also referred to as “bottom air cell”) are connected to an air supply / discharge device (not shown) via a pipe 19. These bottom surface air cells 9a and 9b expand and contract when air is supplied and discharged, and expand in a protruding manner from the bottom surface 11a to press the sites on the back side of both legs housed in the concave leg housing portion 15. The bottom surface air cells 9a and 9b include a first bottom surface air cell 9a provided on one of the left and right sides of the bottom surface 11a (left side in FIGS. 2 and 3), and the bottom surface 1a.

The first side surface air cell 8a and the first bottom surface air cell 9a are for pressing one leg L1.
The second side surface air cell 8b and the second bottom surface air cell 9b are for pressing the other leg L2. The side air cells 8a, 8b and the bottom air cells 9a, 9b can be expanded and contracted at the same time, or can be individually expanded and contracted. Further, the air cells 8a, 8b, 9a, 9b are covers made of cloth or leather. It is covered by the body so that the air cell is not exposed to the outside. The first and second side surface air cells 8a, 8b and the first and second bottom surface air cells 9a,
9b is a bag-shaped synthetic resin sheet material. FIG. 4 shows a sectional view of the air cell in a contracted state, and FIG. 5 shows a sectional view of the air cell in an expanded state. As shown in FIGS. 4 and 5, the air cells 8a, 8b, 9a, 9b are contracted and flat when air is discharged from the inside of the air cell, and fan-shaped when air is supplied to the inside of the air cell. Is formed to expand.

In order to allow a large expansion, the air cell has a bellows structure in which the sheet material is folded at the peripheral edge. When air is supplied to the air cell, the bellows 20 on the peripheral edge can be expanded and greatly expanded, and when air is discharged from the air cell, the bellows 20 can be contracted and made small until it becomes thin and flat. Further, one end of the air cell is arranged so that the air cell does not expand so as to project straight from the surface on which the air cell is provided but expands while curving as shown in FIG. 5 (hereinafter, also referred to as “curve expansion”). An extension regulating member 21 that regulates the extension of the bellows 20 is provided at the edge. This extension regulation member 21
Is configured by a sheet-shaped connecting piece that connects a plurality of folding parts 22 of the bellows 20 to each other so that the intervals between the folding parts 22 do not exceed a certain value.

When the air cell is expanded in a protruding shape by the expansion restricting member 21, one end edge 23 which is restricted by the expansion restricting member 21 expands slightly and the other end edge 24 which is not restricted by the expansion restricting member 21 is large. Expands. That is,
The air cell, as shown by the arrow in FIG.
It expands while curving diagonally to the 1 side and expands into a fan shape. The air cells shown in FIGS. 4 and 5 are adopted as the side and bottom air cells 8a, 8b, 9a, 9b, and as shown in FIGS. 3 and 6, the first and second side air cells 8 are provided.
a and 8b are edges 23 of the air cell whose expansion is restricted.
Is the bottom surface 11a side (lower side in FIGS. 3 and 6),
Largely inflatable air cell with the other end edge 24 of the concave leg storage portion 1
5 is arranged so as to be on the upper opening side (upper side in FIGS. 3 and 6).

Also, the first and second bottom air cells 9a, 9
In b, the one end edge 23 of the air cell whose expansion is regulated is located on the side walls 12a and 12b side, and the other end edge 24 of the air cell, which is largely expandable, is located on the left and right central portion 11b side of the bottom surface 11a. In addition, each air cell a8, 8b, 9
A connection port 25 to the pipes 18 and 19 is provided in each of a and 9b, and the connection port 25 is connected to the bottom member 11 or the side wall 12.
The air cells are connected to the pipes 18 and 19 arranged inside a and 12b, and by this connection, each air cell is attached and fixed to the bottom surface 11a or the side walls 12a and 12b.

Due to the above-described arrangement of the air cells, as shown in FIG. 6, the side surface air cells 8a and 8b are projected and expanded while curving toward the bottom surface 11a, and the bottom surface air cells 9a and 9b are expanded.
Expands while curving toward the side walls 12a and 12b. In addition, the turning (curve) fulcrum of the side air cells 8a, 8b and the bottom air cells 9a, 9b at the time of expansion is the bottom surface 1
The side walls 12a and 12b from 1a are near the rising corner portion 26. As a result of such expansion, the portions 24, 24 near the upper opening of the concave leg housing portion 15 of the first and second side surface air cells 8a, 8b are greatly expanded, and the side surfaces 12a, 12 are formed.
The amount of protrusion from b becomes large. Compared with this, the portion 2 near the bottom surface 11a of the first and second side air cells 8a, 8b
3 and 23 expand a little, and the amount of protrusion from the bottom surface 11a is small. Therefore, as shown in FIG. 7, the first and second side air cells 8a and 8b can press the side portions of the legs L1 and L2 while pressing the legs L1 and L2 from above toward the bottom surface 11a, and are pressed. Both legs L1, L
Even if it is not between the two, it is possible to prevent the legs from escaping sideways (moving so that the two legs come close to each other) to some extent.

Further, the first and second bottom air cells 9a,
For 9b, the left and right center 11b of their bottom surface 11a
The proximate portions 24, 24 expand greatly, and the amount of protrusion from the bottom surface 11a increases. On the other hand, the portions 23, 23 of the first and second bottom surface air cells 9a, 9b near the side walls 12a, 12b expand slightly, and the amount of protrusion from the bottom surface 11a is small. Therefore, as shown in FIG. 7, the first and second
The bottom air cells 9a, 9b connect the legs L1, L2 to the side wall 12
The back sides of the legs L1 and L2 can be pushed up while being pushed to the a and 12b sides.

The bottom air cells 9a, 9b are also squeezed into and pressed by the inner parts of the parts 24, 24 near the bottom central portion 11b. Here, since the expansion amount of the portions 23, 23 of the bottom air cells 9a, 9b near the side walls 12a, 12b is small, the force pressing the outside of the legs L1, L2 is weak. Therefore, in the bottom air cells 9a, 9b, the pressing force by the portions 24, 24 is greater than the pressing force by the portions 23, 23, and the pressing force in the direction in which the legs L1, L2 are separated is generated. In this way, by applying a large pushing force to the inside of the legs L1 and L2 from the outside, a force in the direction of separating the legs left and right is generated, and the legs L1 and L2 can be pressed against the side walls 12a and 12b.

Therefore, even when the legs L1, L2 are pressed from the outside by the side air cells 8a, 8b, the force is received by the force of the bottom air cells 9a, 9b in the direction of separating the legs to the left and right, and the side air cells 8a. , 8b and the bottom air cells 9a, 9b can press the legs L1 and L2 in a sandwiched manner, and the outer side and the inner back side of the legs can be massaged. Therefore, even if there is no member such as a separation hill between both legs, the legs can be pressed without escape and effective massage can be performed.

In this embodiment, the bottom surface 11a has
A vibration device (vibrator) 28 that generates vibration is provided. This vibrating device 28 is embedded in the bottom member 11 and can give a vibration massage to the legs. The location of the vibrating device 28 may be near the left-right center of the bottom surface 11a, below the bottom air cells 9a, 9b, or both. The vibrating device 28 is attached to the bottom surface 1
When it is provided near the left-right center of 1a, it can be placed avoiding the bottom air cells 9a, 9b by locating it between the left and right first bottom air cells 9a and second bottom air cells 9b.
It is possible to prevent the pipes 18 and 19 from getting in the way. Also,
When the vibrating device 28 is located below the second bottom surface air cell, the vibrating device 28 is located immediately below the legs L1 and L2, and vibration can be effectively applied to the legs.

8 and 9 show a leg placement portion 4 (leg air massager) according to a second embodiment of the present invention.
The difference from the first embodiment shown in FIGS. 1 to 7 is the bottom air cell. Bottom air cell 29 according to the second embodiment
Are not separated into right and left, but are formed to be long in the left and right, and have a left and right width such that both legs can be pressed by the same bottom surface air cell 29. The bottom air cell 29 is a flat bag when contracted (see FIG. 8), and when expanded, the left and right central portions 29a largely expand and the left and right ends 29b expand smaller. That is, the bottom air cell 29 expands in a mountain shape. The inflating air cell is obtained by stacking two sheet materials and joining the peripheral edges of these sheet materials to form a bag. Such a bottom air cell 29 is arranged across the bottom left and right central portion 11b so that the left and right central portion 29 substantially coincides with the left and right central portion 11b of the bottom surface 11a.

The bottom surface air cell 29 functions similarly to the bottom surface air cells 9a and 9b of the first embodiment. That is, the left and right central portions 29a of the bottom air cell 29 and the area near the central portion thereof are largely expanded and the protrusion amount from the bottom surface 11a is large, while the left and right end sides 29b, 29b are slightly expanded and the protrusion amount is small. . Therefore, the inner sides of the legs (closer to the left and right center) are pressed more strongly upward, whereas the outer sides of the legs (closer to the side walls 12a and 12b) are pressed weaker. Therefore, the pressing force by the central portion 29a of the bottom surface air cell 29 exceeds the pressing force by the left and right side portions 29b, 29b, and a force for separating the two legs is generated, so that both legs can be pressed against the side walls 12a, 12b.

Comparing the bottom surface air cells 9a and 9b of the first embodiment with the bottom surface air cell 29 of the second embodiment, the former bottom surface air cells 9a and 9b are separated into left and right.
The latter can expand with a smaller amount of air than the bottom air cell 29, and can expand and contract relatively quickly. On the other hand, since the latter bottom air cell 29 presses both legs with the same bottom air cell 29, the latter bottom air cell 9
It is possible to simplify the piping structure for supplying and discharging air as compared with a and 9b. The latter air cell 29
In this case, since it is not necessary to adopt a bellows structure like the former air cells 9a and 9b, the configuration itself of the bottom air cells 9a and 9b can be simplified.

The description of the second embodiment is omitted as in the first embodiment. 10 and 11
[Fig. 4] shows a leg rest 4 (leg air massager) according to a third embodiment of the present invention. The first difference between the third embodiment and the second embodiment is that the side air cells 8a, 8b and the bottom air cell 29 are arranged in a plurality (two) in the longitudinal direction of the leg of the user housed in the concave leg housing portion 15. It is arranged in. The second difference is that the concave leg housing portion 15 constituted by the bottom member 11 and the side walls 12a and 12b is divided into a plurality (two) of longitudinally (longitudinal) leg members 31, 32. It is constituted by a combination, and the interval between the split bodies 31, 32 in the longitudinal direction of the leg is adjustable.

Regarding the first difference, since a plurality of air cells 8a, 8b, 29 are provided in the longitudinal direction of the leg, different portions of the leg accommodated in the concave leg accommodating portion 15 (for example, ankle and calf). ) Can be pressed by separate air cells, compared to pressing the entire leg with a single air cell, local pressing is possible, and a wide variety of massages can be performed by shifting the operation timing of multiple air cells. be able to. Regarding the second difference,

The difference between the fourth embodiment and the first embodiment is that the concave leg storage portion 15 (leg mounting portion 4) formed by the bottom member 11 and the side walls 12a and 12b is divided into a plurality (two) in the left-right direction. It is constituted by a combination of the divided bodies 41, 42 and the distance between the divided bodies 41, 42 in the leg longitudinal direction is adjustable. In other words,
The bottom surface member 11 is divided into left and right parts at the left and right central portions, and the bottom surface 11a can be separated into left and right parts on the first divided body 41 side and the second divided body 42 side. The distance between the left and right side walls 12a and 12b can be adjusted by moving the left and right divided bodies 41 and 42. The first bottom surface air cells 9a are arranged on the first divided body 41 side, and the second bottom surface air cells 9b are arranged on the second divided body 42 side.
