Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air bag (cell) which is divided into a plurality of pieces and integrally attached to a treatment section of a human body, and the cells are inflated by supplying / exhausting compressed air to / from each cell. It is concerned with the improvement of air bags (cuffs) for pneumatic massagers that perform massages by repeating and contracting.

[0002]

2. Description of the Related Art The structure of an air bag in a pneumatic massage device of this type is, for example, a divided single unit made of an elastic body (stretchable material) as disclosed in Japanese Utility Model Publication No. 59-40023. There are air bags (called cuffs) in which the inner bags (called cells) are interconnected and arranged in a horizontal row. (Prior art A)

According to the air bag structure of the prior art A, as shown in FIG. 1, the vicinity of the connecting portion 2 between the cells 1 becomes a non-stretchable portion that is not sufficiently expanded and contracted, and a part of the treatment portion 3 has a bamboo node state. As a result, the unrubbed portion 4 is generated, and a problem that a sufficient massage effect is hardly obtained remains.

As an air bag structure which can solve the above-mentioned problem of the prior art A, for example, there is an air bag structure disclosed in Japanese Utility Model Laid-Open Publication No. HEI 3-21332.
As schematically shown, each cell 5 on the outer layer side arranged in a horizontal line at intervals and each inner layer side arranged in a horizontal line at a staggered position in a staggered state with the cells 5 being shifted. And each cell 5 and 6 is individually accommodated in the same number of outer bags 7 as each cell made of a material having little elasticity such as cloth, and a space between adjacent outer bags 7 is provided. It is sewn and integrally connected. (Prior art B)

[0005] According to the air bag structure of the prior art B, the overlapping portion 8 is formed between each cell 5 on the outer layer side and each cell 6 on the inner layer side. However, when the outer bag 7 is manufactured, a large number of sewn portions 9 are required. In addition, the sewn portion 9 of the outer bag 7 which is located on the treatment section 3 side and accommodates the cell 6, Outer bag 7 to be stored
Therefore, the production is complicated and the cost is high, which is not suitable for mass production.

In the case of the air bag structure of the prior art B, the outer bag 7 is provided with a margin in advance in anticipation of the inflation of the cells 5 and 6 as shown in FIG. Although it is necessary to make the cell large, the extra margin forms a wrinkle as shown in FIG. 3B when the cells 5 and 6 are contracted. In addition, there are problems such as worsening the feel of the skin, and leaving wrinkles on the skin even after massage, which is not preferable from the viewpoint of beauty.

Further, as another air bag structure which can solve the above-mentioned problems of the prior art A, for example, Japanese Utility Model Publication No. 59-11013
As shown schematically in FIG. 4, this air bag structure is formed in an outer cloth 10 formed of a hard cloth and flat, and formed in an inclined meandering state with a soft cloth. The inner cloth 12 has sewing portions 11, 11 with the outer cloth 10 at both ends, and a plurality of cells 13 wrapped between the outer cloth 10 and the inner cloth 12 and arranged in an inclined manner. ing. (Prior art C)

According to the air bag structure of the prior art C, the outer cloth 10 and the inner cloth 12 are not sewn except for the sewn portions 11 at both ends, and the adjacent ends of the cells 13 arranged in an inclined manner. Since the cells are superposed, the cells 13 have the advantage of being able to expand and contract in a bellows shape when the cells 13 are sequentially expanded, thereby reducing the number of non-expanded parts. There is also a possibility that the feel to the skin 3 may be deteriorated, it may become foldable when contracted, it may be caught when it is attached to and detached from the treatment section 3, and it may be difficult to clean the inside when the inside becomes dirty. Was left.

Next, in many air bag structures typified by the prior art A, since the adjacent cells C1 to C5 are fixed so that the positional relationship between them is not shifted, the cells are sequentially fed in a forward state. When the inflation is performed, when one of the adjacent cells expands, the other cell is attracted, and the entire cuff attached to the treatment section slips down in a process as shown in FIG. 5 to impair the massage effect. Since there is a possibility that the cuff needs to be re-attached, there is room for improvement.

Next, in many air bag structures represented by the prior art A, as shown in FIG. 6, each of the cells C1 to C5 has a constant horizontal width along a longitudinal direction, and a vertical width perpendicular to the longitudinal direction. For example, the width of each cell is not uniform since it is formed sequentially wide so as to be adapted to the treatment section such as an arm or a leg. When the air supply switching time for each cell is fixed, the addition of the cell is considered. Pressure may be uneven, impairing uniform massage to the treatment area, or requiring a complicated mechanism or control circuit to individually set the air supply switching time, leaving room for improvement. Was.

Next, in many air bag structures represented by the prior art A, a slide fastener F is attached to a cuff K as shown in FIG. 7 in order to facilitate attachment to a treatment section such as an arm or a leg. Although it is attached, when the cell expands during treatment, a force that expands in the vertical width direction may act and the slider may be pulled down.
There is room for improvement, such as the fact that the cell is not expanded or contracted and a part that remains to be rubbed occurs inside the cell.

Next, in many air bag structures represented by the prior art A, a stretchable material such as latex or vinyl chloride is used as a constituent material of the cell. However, in the case of latex, mass production is required because it is manufactured by a dipping method (a rubber bag is formed by immersing a mold in latex solution and attaching it to the outer periphery). It is necessary to overcome the difficulties and instability of quality due to climate change.In the case of PVC, incineration at the time of disposal may cause a pollution problem, and it should be improved. There was room to be left.

[0013]

SUMMARY OF THE INVENTION Accordingly, the present invention provides an air bag for a pneumatic massager which can solve the above-mentioned problems of the prior art. The cuff is made up of cells, eliminating the non-stretchable parts between each cell to eliminate residual kneading, and the configuration for that purpose is to reduce production man-hours and the number of parts, in particular, to improve productivity and reduce costs It is also possible to improve durability and weather resistance.

Another object of the present invention is to improve the wearability when used by attaching to a treatment section such as an arm or a leg. The purpose of the present invention is to reduce adhesion of the cuff and facilitate wiping when it is attached, and to prevent the position of the cuff from slipping from the treatment section due to expansion and contraction of the cell during use.

Another object is to make the volume of each cell constant so that the massage pressure in each part of the treatment section is constant, or to change the compression force in a desired state by changing the volume of each cell. Is to be able to easily set the volume.

Another object of the present invention is to improve a related portion of a slide fastener for opening and closing the cuff. Particularly, it is possible to prevent a slider of the fastener from being lowered during treatment due to expansion and contraction of a cell. This is to eliminate the unrubbed portion generated inside.

Another object is to improve the heat welding property to the cell, thereby facilitating the installation of the air pressure supply / exhaust port, and providing a partition line in the cell to control the contraction during expansion. In addition, the number and intervals of the welding lines that define the cell C are set as desired so that the strength of the welded portion with respect to air pressure can be improved or the thickness can be adjusted during expansion.

[0018]

An air bag (cuff) for a pneumatic massager according to the present invention comprises an inner sheet wound around a treatment section, and inner cells arranged at intervals on the inner sheet. And outer cells arranged in a state of being bridged between adjacent cells on the inner layer, and outer cells that cover the inner layer and the outer layer and that are connected to the inner sheet at key points. A plastic sheet-like material having airtightness and elasticity and easy to be welded to the cell, comprising a sheet and a fastening device attached to a joint end of the outer sheet to perform a cuff attaching / detaching operation. The outer peripheral edge of the sheet material was welded to form a bag. (Claim 1)

In the cuff having the above structure, the inner and outer cells are alternately arranged, so that the non-stretchable portion between the cells can be eliminated to eliminate the remaining kneading as in the case of the conventional technology B or the conventional technology C. In particular, the inner and outer cells are integrated by welding a plastic sheet material, so that the number of manufacturing steps and the number of parts can be reduced and productivity can be improved as compared with the prior arts B and C. .

In the cuff according to the above configuration, the cell on the inner layer side is formed by welding an inner sheet made of the same material as the cell and a cell sheet arranged on the upper surface of the cell at a distance. The cell on the side is preferably formed by fusing two superposed cell sheets in a bag shape in advance, and only the both ends along the longitudinal direction of the cuff are welded between adjacent cells on the inner layer side. (Claim 2)

According to the cell having the above-mentioned structure, the portion in contact with the treatment section is an inner sheet which is elastic and has no unevenness on the surface.
Since a step is not generated at the time of inflation unlike the conventional technology C, the touch is good and the wearability is improved, and the dirt is easily wiped off and the cleanliness is maintained.

According to the cell having the above structure, the cells on the inner layer side are connected and fixed to each other and interlock, but the cells on the outer layer side are separated from the cells on the inner layer side and do not interlock. Each time the cells are sequentially expanded or contracted, each cell adjacent thereto is not drawn, so that the cuff can be prevented from slipping down with respect to the treatment section.

When the cell is formed of a polyurethane sheet, it has airtightness and elasticity, and is excellent in weather resistance and durability, so that it can maintain a stable elastic state even when used for a long period of time, and can have a desired welded state by heating. It is easy to manufacture and mass-produced industrially, so that products can be manufactured at low cost, and because it has excellent weather resistance and durability, it can maintain a stable expansion and contraction state, and it can prevent pollution problems such as PVC. Since it does not occur, it can be incinerated when discarded. (Claim 3)

Since a large number of ventilation holes can be formed in the inner sheet between the cells on the inner layer side, the ventilation holes prevent the inside from being stuffy when the cuff is attached to the treatment section. And make the wearing feeling good. (Claim 4)

In each of the cells, it is easy to change the pressing force by changing the welding position and setting the volume of each cell to a desired value. Even when the air supply switching time is constant, the pressure applied to each cell is constant, and a uniform massage for the treatment section can be obtained. (Claim 5)

When a slide fastener is used as the fastening tool, an extension protruding from the joining end of the outer sheet is provided at the opening / closing start end side of the slide fastener.
The slider is prevented from being lowered when the cell expands during treatment, and the cuff can be prevented from being opened without permission. (Claim 6)

In each of the cells, overlapping portions are provided at both ends orthogonal to the longitudinal direction of the cuff, and the overlapping portions are arranged inside the joining end portion of the outer sheet. The remaining massage can be eliminated. (Claim 7)

In each of the cells, bulging portions are provided at both ends orthogonal to the longitudinal direction of the cuff, and the bulging portions are arranged inside the joining end portion of the outer sheet. It is possible to eliminate the remaining unrubbed portion. (Claim 8)

If the supply / exhaust port for each of the cells is constituted by a tube for piping, the tip of which is inserted into the cell and connected and fixed by welding, the structure is simpler and cheaper than the prior art, Pipes can be prevented from dropping inside. (Claim 9)

In each of the above cells, a partition line for controlling the direction in which the cell contracts when expanded can be formed by welding depending on the application or the like, and the partition line is provided by utilizing the characteristics of the cell which can be easily heated and welded. And, since it is difficult to shrink in the direction along the partition line and easy to shrink in the direction orthogonal to the direction, by the desired partition line adapted to the shape of the treatment section,
The degree of adhesion to the treatment section can be improved, and contraction in a specific direction can be prevented. (Claim 10)

[0031]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an air bag (cuff) for a pneumatic massager according to the present invention will be described in detail based on a preferred embodiment with reference to the accompanying drawings. FIG. FIG. 9 is a schematic longitudinal sectional view of the cuff, FIG. 10 is a schematic exploded perspective view of the cuff, and FIG. 11 is a configuration of each cell in the cuff. Each of the schematic exploded perspective views to be described is shown.

The cuff K to which the present invention is applied is composed of a plurality of trapezoidal cell sheets 21 whose diameters are sequentially increased along the longitudinal direction with respect to the upper surface of one trapezoidal inner sheet 20. , 23, and 25 are arranged at intervals, and the entire outer peripheral portion of the cell sheet is welded to the inner sheet 20 to form a bag-like shape, whereby each of the inner layers as shown in FIG. Cells C21, C23, and C25 are configured.

The cells C22 and C24 on the outer layer are
After the two trapezoidal cell sheets 22, 22 and the cell sheets 24, 24 are superimposed, the entire outer periphery of the cell sheet is welded to each other to form a bag shape, and then the inner sheet 20 is formed. Each cell C21, C2 on the inner layer side adjacent to the upper surface
3 and the cells 23 and C25 are arranged in an erected state (alternately in an overlapping manner), and the respective cells C2
2. Only the two ends of the outer peripheral edge of C24 along the longitudinal direction are welded to the upper surface of the inner sheet 20 and the cells on the inner layer side.

Further, each of the cells C21, C23,
As another form of C25, each cell C22, C2 on the outer layer side
As in the case of No. 4, a diagram in which two cell sheets are superimposed, the entire outer peripheral edges thereof are welded to each other to form a bag, and the entire circumference is fixed to the upper surface of the inner sheet 20 by sewing. A configuration as shown in FIG. 9B is also possible.

9 (a) and the inner layer side cell structure (the latter) shown in FIG. 9 (b), the inner sheet 20 of the inner sheet 20 is in the former case. Since each of the cells C21, C23, and C25 is configured using a part thereof, one cell sheet is reduced, and
Since the cells C21, C23, C25 and the inner sheet 20 can be manufactured simultaneously, there is an advantage that the number of manufacturing steps can be reduced.

In the former case, a relatively expensive stretchable sheet material made of polyurethane or the like is used for the inner sheet 20 other than the parts constituting each cell, that is, between the cells. In addition to the cost increase, the stretch sheet material such as polyurethane has poor air permeability, so it is necessary to provide extra ventilation holes to prevent stuffiness when the cuff K is attached. There are disadvantages.

On the other hand, in the latter case, since the inner sheet 20 can be made of a cloth sheet material of a different material from the cells C21, C23, C25, a stretch sheet made of a relatively expensive polyurethane or the like is used. On the other hand, each cell made of an elastic sheet material has the advantage that the amount of use of the sheet material can be reduced, and that the cloth sheet material has an advantage that it does not easily become stuffy when the cuff K is attached even if the cuff K is not provided even if a ventilation hole is not provided. Are welded to form a bag, and the respective cells are sewn and fixed to the inner sheet 20 made of a cloth sheet material. Therefore, there are disadvantages such that the number of manufacturing steps and the number of parts are increased as compared with the former case.

The inner sheet 20 and each cell C21 to C21-2
5 is made of a plastic sheet material having airtightness and elasticity and easy to be welded by heating.
The air supply / discharge ports 26 (a to e) through which tubes and the like are inserted and piped are provided at 21 to 25, respectively.
On the opposite side of the inner sheet 20 that is the side,
The outer sheet 28 made of a cloth material with little elasticity is arranged in a manner to cover the inner sheet 25, and key points (at least four corners) between the inner sheet 20 and the outer sheet 28 are sewn and connected and fixed to each other to form an integral unit as a whole. Construct the cuff K.

Further, slide fasteners 29 are attached to the outer sheet 28 at both side edges along the longitudinal direction of the outer sheet 28 as fasteners for fastening the cuff K so that the cuff K can be opened and closed.
When the slide fastener 29 is opened, the cuff K is unfolded in a flat shape, and when the slide fastener 29 is closed, the cuff K forms a tubular body that is mounted in a manner that the inner sheet 20 abuts on the treatment section 27.

In the cuff according to the above-described configuration, the non-stretchable portions generated between the cells are eliminated by overlapping the cells (inner bags) in two layers in a state where the positions thereof are staggered in the same manner as in the case of the prior art B. Although it is possible to eliminate the residual rubbing, but compared to the conventional technology B, which requires complicated sewing and is difficult to mass-produce and costs high, the plastic sheet material cut into a desired shape is welded in a polymerized state and integrated. The inner sheet 20 and the cells C21 to C25 can be easily and inexpensively mass-produced.

Further, since one inner sheet 20 having elasticity is provided on the inner side in contact with the treatment section 27 of the human body such as an arm or a leg, wrinkles are generated when contracted as in the case of the prior art B. As in the case of the prior art C, there is no step or folds as in the case of the conventional technology C, so that the feel to the treatment section 27 is improved, and even when dirt or dirt adheres, it is easily wiped and clean. Can be kept in a state.

The plastic sheet material is preferably air-tight and stretchable and satisfies conditions such as easy welding by heating. For example, it is desirable to use polyurethane, and the material is industrially mass-produced. The cell can be manufactured by welding the raw material sheet, so that the manufacturing cost is low, the weather resistance and durability are excellent, so that the stable expansion and contraction state is maintained, and the incineration process when disposing Also does not cause pollution problems such as vinyl chloride,
There are advantages such as.

Next, instead of connecting and fixing all the ends of the cells adjacent to each other along the longitudinal direction as in the above configuration,
By connecting and fixing every other cell, that is, the cells C21, C23, and C24 on the inner layer side are connected and fixed to each other and interlock, but the cells C22 and C24 on the outer layer side are separated from the cells on the inner layer side. Since each cell is expanded or contracted sequentially, it behaves as shown in FIG. 12 and does not draw each adjacent cell each time, so that it is possible to prevent the treatment section 27 from slipping down.

It is easy to set the volume of each cell C as desired by heat welding. For example, as shown in FIG. 13, by forming the volumes S1 to S5 of the cells C21 to 25 equally in advance. Even when the air supply switching time for each cell is constant, the pressing force of each cell can be constant, uniform massage can be performed on the treatment section, and the air supply switching time can be individually set. Thus, a configuration that does not require a complicated mechanism or control circuit is easily obtained, and conversely, it is also easy to set a desired volume in order to change the compression force of each cell C21 to C25.

The slider 3 of the slide fastener 29 attached to the outer sheet 28 to open and close the cuff K
As shown in FIG.
If the extension 31 is provided so as to protrude from the large-diameter side end (for example, about 20 mm), even when the cell expands during treatment, the force that expands in the vertical width direction does not act on the closed slider portion. Can be prevented from opening the cuff K without permission.

Next, various other modifications of the air bag of the present invention will be described with reference to FIGS. 15 to 25. For example, in the case of the prior art, a cell for sewing is provided inside the mounting portion of the slide fastener. Since it is not arranged and a streaky unrubbed portion is generated along the long direction of the cuff, as a means for solving this, for example, as shown in FIG. 15, the end of the cell C is polymerized inside the slide fastener 29. And the overlapping portions 32 and 33 of the cell C
Is formed in a thin shape of about の of the other portion.

As another means for eliminating the remaining kneading of the mounting portion of the slide fastener 29, for example, as shown in FIG.
The end shape of the cell C is set in advance so that the joint end swells when the cell C is expanded as shown by, and bulges 34 and 35 are formed to fill gaps inside the mounting portion. To manufacture.

As a means for preventing the inside from becoming stuffy when the cuff K is attached to the treatment section 27, an inner sheet 20 made of a non-breathable plastic sheet material is used.
Among the cells that do not constitute cell C, for example, between cell C21 and cell C23 and between cell C23 and cell C2 in FIG.
A large number of ventilation holes 36 can be formed in the inner sheet 20 between 5.

Next, the cell C was formed by using the inner sheet 20 and the cell sheet made of a plastic sheet material having airtightness and elasticity, and easily welded by heating. For example, as shown in FIG. 17, the supply / discharge ports 26 (a to e) for supplying / exhausting air can be directly connected to a cell C by inserting a tube 37 for piping and fixedly connected by a welding portion 38. In addition, the configuration is simple and inexpensive as compared with the prior art, and the pipes can be prevented from falling off during treatment.

In particular, if the tube 37 is welded in a state where it is inserted all the way into the cell C, it is possible to prevent the base of the welded portion 38 from bending and closing the flow passage, and to prevent aesthetic, functional, or manufacturing problems. If the welding part 38 does not want to protrude from the cell C for the reason described above, the form of FIG. 17B is adopted, and if there is no such restriction, the form of FIG. 17A is adopted. You can use them properly.

Next, by making use of the feature of the cell C, which is easy to heat and weld, by providing a desired partition line by welding to the cell C as shown in FIG. 18, it is difficult to shrink in the direction along the partition line. Since it is easy to shrink in the direction perpendicular to it, it is possible to control the way of shrinkage during expansion by this partition line, and by the desired partition line adapted to the shape of the treatment section, the degree of adhesion to the treatment section is improved. Or shrinkage in a specific direction can be prevented.

For example, in the case where the treatment section is a part which is not substantially changed in thickness but approximates to a substantially cylindrical shape like the upper arm, FIG.
When the partition lines 39 and 40 are provided alternately from both ends in the short direction as shown in FIG. 8 (a), the cells C are uniformly shrunk in the longitudinal direction. In contrast, when a partition line is provided parallel to the longitudinal direction (not shown), contraction in the longitudinal direction can be prevented.

In the case where the treatment section is a part such as an inflated shin, whose thickness is greatly different between the upper side and the lower side and approximates to a conical shape, as shown in FIG. When the partition line 41 is provided from one end to the other end, it is possible to form a fan shape in which one end side is shrunk and the other end side is not shrunk. Can be planned.

In addition, in order to improve the strength of the welded portion against the air pressure supplied to the cell C by taking advantage of the characteristics of the cell C which is easy to heat weld, the number of welding lines defining the cell C is doubled or tripled. In order to adjust the thickness of the cell C when the cell C expands as desired, the interval between the welding lines defining the cell C can be set and easily adjusted.

Next, in many air bag structures represented by the prior art A, as shown in FIG. 6, each of the cells C1 to C5 has a constant horizontal width along a longitudinal direction, and a vertical width perpendicular to the longitudinal direction. For example, the width of each cell is not uniform since it is formed sequentially wide so as to be adapted to the treatment section such as an arm or a leg. When the air supply switching time for each cell is fixed, the addition of the cell is considered. Since the pressure may vary and the uniform massage of the treatment part may be impaired, it is necessary to individually set the air supply switching time to achieve the uniform massage, and for that purpose, a complicated mechanism or control is required. In some cases, a circuit was required, leaving room for improvement.
