Description

[0001]
BACKGROUND OF THE INVENTION
In the present invention, a single air bag (cell) divided into a plurality of parts is integrally connected to be attached to a treatment part of a human body, and compressed air is supplied to and exhausted from each cell, and massage is performed by repeated expansion and contraction. It relates to the improvement of the air bag (cuff) for the pneumatic massager.
[0002]
[Prior art]
As the structure of the air bag in this type of pneumatic massager, for example, an air bag structure disclosed in Japanese Utility Model Publication No. 59-40023 is divided into a single inner bag (cell) made of an elastic body (stretchable material). There are air bags (called cuffs) that are connected to each other and arranged in a horizontal row. (Prior art A)
[0003]
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 is a non-stretchable portion that is not sufficiently stretched and left in a part of the treatment portion 3 in a bamboo knot state. The part 4 was generated, and the problem that it was difficult to obtain a sufficient massage effect remained.
[0004]
Moreover, as an air bag structure that can solve the above-mentioned problem of the prior art A, there is an air bag structure disclosed in, for example, Japanese Utility Model Laid-Open No. 3-21332. This air bag structure has an interval as shown schematically in FIG. Each cell 5 on the outer layer side arranged in a horizontal row with each other, and each cell 6 on the inner layer side arranged in a horizontal row at intervals in a staggered state shifted from each cell 5, these The cells 5 and 6 are individually accommodated in the same number of outer bags 7 as each cell made of a material having low stretchability such as cloth, and the adjacent outer bags 7 are sewn together and integrally connected. Is. (Conventional technology B)
[0005]
According to the air bag structure of the prior art B, since the overlapping portion 8 is formed between each cell 5 on the outer layer side and each cell 6 on the inner layer side, the remaining residue that was a problem of the prior art A is eliminated. However, when the outer bag 7 is manufactured, a large number of sewing parts 9 are required. In particular, the sewing part 9 of the outer bag 7 that is located on the treatment part 3 side and accommodates the cell 6 is an outer part that accommodates the cell 5. Since it is sewed with the middle part of the bag 7, its manufacture is complicated and costly and unsuitable for mass production.
[0006]
However, in the case of the air bag structure of the prior art B, the outer bag 7 is made larger with a margin in advance in anticipation of the expansion of the cells 5 and 6, as shown in FIG. Although it is necessary, the margin will form wrinkles as shown in FIG. 3 (b) when the cells 5 and 6 are contracted. In addition to worsening, wrinkles were left on the skin even after the massage, and problems such as undesirable aesthetics were left.
[0007]
Furthermore, as another air bag structure that can solve the above-mentioned problem of the prior art A, there is an air bag structure disclosed in, for example, Japanese Utility Model Publication No. 59-11013, and this air bag structure is schematically shown in FIG. An outer cloth 10 formed flat with a hard cloth, an inner cloth 12 formed in a meandering state inclined with a soft cloth and having sewing parts 11, 11 with the outer cloth 10 at both ends, and the outer cloth 10 A plurality of cells 13 are disposed between the inner cloths 12 and are arranged in an inclined manner. (Prior art C)
[0008]
According to the air bag structure of the prior art C, the adjacent ends of each cell 13 arranged in an inclined manner are overlapped, so that when each cell 13 is inflated sequentially, it expands and contracts in a bellows shape and is not inflated. On the other hand, there is an advantage that the portion can be reduced, but this overlapped portion may cause a step when expanded to make the treatment part 3 feel uncomfortable, or it may become trapped when attached to the treatment part 3 due to a hook shape when contracted. There is also a possibility that it is difficult to clean the interior when it gets dirty, leaving room for improvement.
[0009]
Next, in many air bag structures represented by the prior art A, since the positional relationship between the adjacent cells C1 to C5 is not shifted, each cell is expanded in a progressive state. When one of the adjacent cells expands, the other cell is drawn, and the entire cuff attached to the treatment part causes a slip-down phenomenon in the process as shown in FIG. There was a possibility that it would be necessary to put it on again, leaving room for improvement.
[0010]
Next, in many air bag structures represented by the prior art A, as shown in FIG. 6, the cells C1 to C5 have a constant horizontal width along the longitudinal direction, and the vertical width orthogonal to this is, for example, an arm or Since the width of each cell is gradually increased in conformity with the treatment part such as a leg, the volume of each cell is not uniform, and when the air supply switching time for each cell is constant, the applied pressure of each cell varies. The uniform massage for the treatment part is damaged, and it is necessary to set the air supply switching time individually to achieve the uniform massage, which requires a complicated mechanism or control circuit. There was still room for improvement.
[0011]
Next, in many air bag structures represented by prior art A, for example, a slide fastener F is attached to the cuff K as shown in FIG. However, when the cell expands during treatment, a force that expands in the vertical width direction may be applied to pull down the slider, and inside the slide fastener F, the cell does not expand and contract and a leftover portion is generated. There was still room for improvement.
[0012]
Next, in many air bag structures represented by the prior art A, a stretch material such as latex or vinyl chloride is used as a constituent material of the cell, but in terms of durability and weather resistance when used for a long time. It is not always sufficient, and in the case of latex, it is difficult to achieve mass production because it is manufactured by a dipping method (a rubber bag is formed by immersing the mold in the latex liquid and adhering it to the outer periphery). In the case of vinyl chloride, incineration at the time of disposal may cause pollution problems, so there is room for improvement. It was left.
[0013]
[Problems to be solved by the invention]
Therefore, the present invention provides an air bag for a pneumatic massager that can solve the problems of the prior art as described above, and one of its purposes is to configure the cuff with inner and outer cells arranged alternately, In addition to eliminating non-stretching parts between cells and eliminating stagnation, the configuration for that purpose can particularly reduce the number of manufacturing steps and the number of parts to improve productivity and reduce costs. It is also possible to improve durability and weather resistance.
[0014]
Another purpose is to improve the wearability when worn and used on treatment areas such as arms and legs, especially to improve the feel and breathability when worn, and to adhere dirt. It is to reduce this and facilitate wiping when adhered, and to prevent the position of the cuff from dropping from the treatment part due to expansion and contraction of the cell during use.
[0015]
Another purpose is to make the cell volume constant by changing the volume of each cell to make the massage pressure constant in each part of the treatment area, or changing the pressure of each cell by changing the volume of each cell. It is to make it easy to set.
[0016]
Another purpose is to improve the related parts of the slide fastener that opens and closes the cuff, especially to prevent the fastener slider from being pulled down during treatment due to the expansion and contraction of the cell, and to occur inside the slide fastener. It is to eliminate the leftover part.
[0017]
As another purpose, by improving the heat weldability to the cell, it is possible to easily attach the air supply / exhaust port, or to provide a partition line in the cell to enable control of the contraction during expansion, The desired number and interval of the welding lines for defining the cell C are set as desired so that the strength of the welded portion against the air pressure can be improved or the thickness can be adjusted during expansion.
[0018]
[Means for Solving the Problems]
An air bag for a pneumatic massager (cuff) according to the present invention includes an inner sheet wound around a treatment portion, inner layer-side cells arranged at intervals on the inner sheet, and adjacent inner layer-side cells. Each cell on the outer layer side arranged between the cells in an erected state, an outer sheet that covers each cell on the inner layer side and the outer layer side, and a principal point is fixedly connected to the inner sheet, and a joining end of the outer sheet The cell is made of a fastening material that attaches and detaches the cuff, and the cell is made of a plastic sheet material that is airtight and stretchable and easily welded. The peripheral edge was welded to form a bag .
[0019]
In the cuff according to the above configuration, since the inner and outer cells are arranged in a staggered manner, it is possible to eliminate the non-stretching portions by eliminating the non-stretchable portions between the cells 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 plastic sheet materials, so that the number of manufacturing steps and the number of parts can be reduced and the productivity can be improved as compared with the conventional techniques B and C.
[0020]
In the cuff configured as described above, the cell on the inner layer side is configured by welding an inner sheet formed of the same material as the cell and a cell sheet disposed on the upper surface of the cell, and the cell on the outer layer side. It is desirable that two polymerized cell sheets are welded in advance to form a bag shape, and only both end portions along the longitudinal direction of the cuff are welded between adjacent cells on the inner layer side .
[0021]
According to the cell of the above configuration, the portion that contacts the treatment part is a stretchable inner sheet with no irregularities on the surface, so that wrinkles are generated when contracted as in the prior art B, or when expanded as in the prior art C Since no step is generated, the touch is good and the wearability is improved, and the dirt can be easily wiped off and kept clean.
[0022]
Also, according to the cell of the above configuration, the cells on the inner layer side are connected and fixed to each other and interlocked, but the cells on the outer layer side are separated from the cells on the inner layer side and do not interlock with each other. When contracted, the adjacent cells are not drawn each time, and the cuff can be prevented from sliding down with respect to the treatment portion.
[0023]
When the cell is formed of a polyurethane sheet, it has airtightness and stretchability, and is excellent in weather resistance and durability, so that a stable stretched state is maintained even during long-term use, and desired welding is easy by heating. Yes, because it is mass-produced industrially, the product can be manufactured at low cost, and since it has excellent weather resistance and durability, it can maintain a stable expansion and contraction, and does not cause pollution problems such as vinyl chloride. It can also be incinerated when discarded .
[0024]
Since the inner sheet can be provided with a large number of vent holes in the portion between the cells on the inner layer side, it is possible to prevent the inside from being steamed when the cuff is attached to the treatment part. Yes, to improve the feeling of wearing .
[0025]
Each cell can easily change the compression force by changing the welding position and setting the volume of each cell as desired. Especially, when the cells have the same volume, the air supply to each cell Even when the switching time is made constant, a uniform massage can be obtained with respect to the treatment part by keeping the pressure applied to each cell constant. (Claim 5)
[0026]
If a slide fastener is used as the fastening device and an extension portion is provided on the starting end side where the slide fastener is opened and protruded from the joining end portion of the outer sheet, the slider is lowered when the cell expands during treatment. Can be prevented, and the cuff can be prevented from opening without permission .
[0027]
Each cell is provided with overlapping portions at both ends orthogonal to the longitudinal direction of the cuff, and when the overlapping portions are arranged inside the joining end portion of the outer sheet, it is possible to leave a stagnation of the fastener portion that has occurred in the prior art. Can be resolved .
[0028]
When each cell is provided with a bulging portion at both ends perpendicular to the longitudinal direction of the cuff and the bulging portion is arranged inside the joining end portion of the outer sheet, the stagnation of the fastener portion that has occurred in the prior art The remaining can be eliminated .
[0029]
The air supply / exhaust port for each cell is composed of a tube for piping that is connected and fixed by welding by inserting a tip portion into the cell, and is simpler and less expensive than the prior art, and is also piped during treatment. Can be prevented from falling off .
[0030]
In each cell, a partition line for controlling the shrinking direction of the cell at the time of expansion can be formed by welding according to the use etc., and the partition line is provided by taking advantage of the features of the cell that is easy to heat-weld. Because it is difficult to shrink in the direction along the line and easy to shrink in the orthogonal direction, the desired partition line adapted to the shape of the treatment part can be used to improve the degree of adhesion to the treatment part, or in a specific direction Can be prevented .
[0031]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an air bag (cuff) for a pneumatic massager according to the present invention will be described in detail with reference to the accompanying drawings based on a preferred embodiment thereof. FIG. 8 shows the entire cuff in a state where a fastener is opened. 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 schematic exploded perspective view illustrating the configuration of each cell in the cuff. Each figure is shown.
[0032]
The cuff K to which the present invention is applied is a plurality of trapezoidal cell sheets 21, 23, whose diameters are sequentially increased along the longitudinal direction with respect to the upper surface of the single trapezoidal inner sheet 20. 25 are arranged at intervals, and the entire outer peripheral edge portion of the cell sheet is welded to the inner sheet 20 to form a bag, whereby each cell C21 on the inner layer side as shown in FIG. C23 and C25 are configured.
[0033]
Each cell C22, C24 on the outer layer side superposes two trapezoidal cell sheets 22, 22 and cell sheets 24, 24, and welds the entire outer peripheral edge of the cell sheet to each other. After forming into a bag shape, each cell C21, C23 and each cell 23, C25 on the inner layer side adjacent to the upper surface of the inner sheet 20 are arranged in an erected state (alternately in an overlapping manner). Of the outer peripheral edge portions of C22 and C24, only both end portions along the longitudinal direction are welded to the upper surface of the inner sheet 20 and each cell on the inner layer side.
[0034]
Furthermore, as another form of the cells C21, C23, C25 on the inner layer side, as in the case of the cells C22, C24 on the outer layer side, two cell sheets are superposed and the entire outer peripheral edge portion is mutually connected. A configuration as shown in FIG. 9B is also possible in which the entire periphery is fixed to the upper surface of the inner sheet 20 by sewing in a state of being welded and formed into a bag shape.
[0035]
Comparing each cell structure on the inner layer side shown in FIG. 9A (the former) and each cell structure on the inner layer side shown in FIG. 9B (the latter), in the former case, a part of the inner sheet 20 is Since each cell C21, C23, C25 is configured by using one cell sheet, each cell C21, C23, C25 and the inner sheet 20 can be manufactured at the same time, thereby reducing the manufacturing process. There are advantages that are possible.
[0036]
In the former case, a stretchable sheet-like material such as relatively expensive polyurethane is also used between the inner sheet 20 portions other than the portions constituting each cell, that is, between the cells. The stretchable sheet-like material such as polyurethane has poor air permeability, so there is a disadvantage in that it is necessary to provide a special vent hole to prevent stuffiness when the cuff K is attached. .
[0037]
On the other hand, in the latter case, the inner sheet 20 can be made of a cloth sheet material that is a different material from the cells C21, C23, C25. The amount of use is small, and there is an advantage that it is hard to get stuffy when cuff K is installed even if there is no vent hole due to the breathability of the cloth sheet material, but each cell made of stretch sheet material is welded Then, since each cell is sewn and fixed to the inner sheet 20 made of a cloth sheet material after being manufactured into a bag shape, there are disadvantages such as an increase in the manufacturing process and the number of parts compared to the former case.
[0038]
The inner sheet 20 and the cells C21 to 25 are made of a plastic sheet material that is airtight and stretchable and can be easily welded by heating, and a tube or the like is inserted into each of the cells C21 to 25. The air supply / exhaust ports 26 (a to e) are equipped, and the opposite side of the inner sheet 20 on the treatment part 27 side is made of a cloth sheet material with less stretchability in a mode of covering each cell C21 to 25. The outer sheet 28 is disposed, and important points (at least four corners) between the inner sheet 20 and the outer sheet 28 are sewn and fixed to form an integral cuff K as a whole.
[0039]
Further, the outer sheet 28 is fitted with slide fasteners 29 on both side edges along the longitudinal direction of the outer sheet 28 as a fastener for fastening the cuff K so that the cuff K can be opened and closed. When the slide fastener 29 is closed, the cuff K forms a cylindrical body that is mounted in such a manner that the inner sheet 20 comes into contact with the treatment portion 27.
[0040]
As in the case of the prior art B, the cuff according to the above configuration overlaps each cell (inner bag) in two layers in a staggered position, thereby eliminating the non-stretchable portion generated between the cells and leaving a stagnation. The inner sheet 20 is made of a plastic sheet material cut into a desired shape and integrated in a polymerized state compared to the conventional technology B, which requires complicated sewing, is difficult to mass-produce, and is expensive. And each cell C21-25 can be mass-produced easily and cheaply.
[0041]
Further, since one inner sheet 20 having elasticity is provided on the inner side that contacts the human body treatment portion 27 such as an arm and a leg, it is wrinkled when contracted as in the case of the prior art B. As in the case of Technology C, there is no level difference or a wrinkle-like shape, so that the touch to the treatment part 27 is improved, and even when dust or dirt adheres, it is easily wiped off and kept clean. it can.
[0042]
As the plastic sheet material, it is preferable to use polyurethane, for example, as a material sheet that has airtightness and stretchability and satisfies the conditions such as easy welding by heating. Since the cell can be manufactured by welding, the manufacturing cost is low, the weather resistance and durability are excellent, so that a stable expansion and contraction state is maintained, and even if it is incinerated when discarded, vinyl chloride There are advantages such as not causing pollution problems such as.
[0043]
Next, the cells C21 and C23 on the inner layer side are fixedly connected to each other without connecting and fixing all the ends of the cells adjacent to each other along the longitudinal direction as in the above-described configuration. , C24 are linked and fixed to each other, but each cell C22, C24 on the outer layer side is separated from each cell on the inner layer side and is not linked, so when each cell is expanded or contracted sequentially in FIG. It is possible to prevent the treatment unit 27 from sliding down without attracting adjacent cells each time.
[0044]
In addition, 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 in advance equally, Even when the air supply switching time is constant, the applied pressure of each cell can be made constant, uniform massage can be performed on the treatment part, and the air supply switching time is individually set Therefore, a configuration that does not require a complicated mechanism or control circuit can be easily obtained, and conversely, it is easy to set a desired volume in order to change the compression force of each of the cells C21 to C25.
[0045]
Further, the starting end side to open the slider 30 of the slide fastener 29 to be attached to the outer sheet 28 to open and close the cuff K, (for example, about 20 mm) than the larger diameter end of the outer sheet 28 as shown in Figure 14 projecting If the extension part 31 to be provided is provided, even when the cell expands during treatment, the closed slider part does not have the force of expanding in the vertical width direction, so that the cuff K can be opened freely by pulling down the slider. Can be prevented.
[0046]
Next, other various modifications of the air bag according to the present invention will be described with reference to FIGS. 15 to 25. For example, in the case of the prior art, cells are not arranged inside the mounting portion of the slide fastener for sewing. A streak-like leftover portion is generated along the long direction of the cuff. As a means for eliminating this, for example, as shown in FIG. 15, the end of the cell C is superposed inside the slide fastener 29. While extending, the superposition | polymerization parts 32 and 33 of the said cell C are formed in the thin shape of about 1/2 of other parts.
[0047]
Further, as another means for eliminating the stagnation of the mounting portion of the slide fastener 29, for example, as shown in FIG. 16, when the cell C is expanded, the joining end portion bulges and fills the gap inside the mounting portion. The end shape of the cell C is set in advance so that the bulging portions 34 and 35 are formed.
[0048]
In addition, as a means for preventing the inside from being steamed when the cuff K is attached to the treatment portion 27, a portion of the inner sheet 20 formed of a non-breathable plastic sheet material, for example, a figure. 11, a large number of air holes 36 can be formed in the inner sheet 20 between the cells C21 and C23 and between the cells C23 and C25.
[0049]
Next, the cell C is formed by using the inner sheet 20 and the cell sheet made of a plastic sheet material that is airtight and stretchable and can be easily welded by heating. For example, as shown in FIG. 17, the supply / exhaust ports 26 (a to e) can be directly connected to the cell C by inserting a tube 37 for piping and fixedly connected by a welded portion 38. Compared to the above, it is simple and inexpensive, and it is possible to prevent the pipe from falling off during treatment.
[0050]
In particular, when welding is performed with the tube 37 inserted to the back of the cell C, it is possible to prevent an accident in which the base portion of the welded portion 38 is bent and closes the flow path, and for aesthetic, functional, or manufacturing reasons. If the welded portion 38 is not desired to protrude from the cell C, the form shown in FIG. 17B is adopted. If there is no such restriction, the form shown in FIG. 17A is adopted. it can.
[0051]
Next, taking advantage of the features of the cell C that is easy to heat-weld, if a desired partition line by welding is provided for the cell C as shown in FIG. 18, the direction along the partition line is difficult to shrink and is orthogonal. Therefore, it is possible to control the contraction method during expansion by using this partition line, and the desired partition line adapted to the shape of the treatment part can improve the degree of adhesion to the treatment part. Or shrinkage in a specific direction can be prevented.
[0052]
For example, in the case where the treatment part is a part that is approximately cylindrical and does not change in thickness, such as the upper arm part, the partition lines 39, 40 alternately from both ends in the short direction as shown in FIG. Is provided, the cell C is contracted uniformly in the longitudinal direction, so that the degree of adhesion of the cell C can be improved with respect to the upper arm portion which is the treatment portion, and conversely, a partition line is provided in parallel with the longitudinal direction ( If the illustration is omitted), contraction in the longitudinal direction can be prevented.
[0053]
Further, in the case where the treatment part is a part that is substantially different from the upper side and the lower side and has an approximate conical shape, such as an inflated shin, from one end side in the short direction as shown in FIG. When the partition line 41 is provided on the other end side, it can be formed into a fan shape in which one end side is contracted and the other end side is not contracted. it can.
[0054]
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 features of the cell C that is easy to heat-weld, the number of welding wires defining the cell C is arranged in parallel or double. In order to adjust the thickness at the time of expansion of the cell C to a desired value, it is possible to easily adjust the distance between the welding lines defining the cell C.
