Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a compression device for a pneumatic massager that expands and contracts a bag body having an airtight chamber by supplying and exhausting compressed air to massage legs, arms, and the like.
[0002]
[Prior art]
In general, the pressure massage device for a pneumatic massager is formed in a sheet shape with a plurality of airtight chambers arranged side by side. When the pressure device is wound around a massage site such as an arm or a leg, The slide fasteners sewn on the joint ends of both edges are opened and closed.
[0003]
The compressed air inlet / outlet provided in each airtight chamber of this seat member and the compressed air supply source are connected via an air hose to supply / exhaust compressed air in units of airtight chambers, and massage parts such as legs and arms. From the periphery to the center, the hermetic chamber is inflated and contracted in order to perform massage.
However, if the opening / closing operation of the slide fastener is repeated with the use of the compression tool, the fastener itself is worn, and the slide fastener may be easily pulled down during use.
[0004]
Further, as shown in FIG. 13, the slide fastener 3 is sewn to the joining end portion of the sheet member 2 having the airtight chamber 1, and in this case, the opening / closing start end 4 of the slide fastener 3 is in the vicinity of the end portion of the airtight chamber 1. Therefore, when the hermetic chamber 1 is expanded, a component force f distributed in the opposite direction around the slide fastener 3 is generated with respect to the sheet member 2 as indicated by the arrow in FIG.
Due to this component force f, the slide fastener 3 is given a force in the pulling-down direction (arrow A), and the slide fastener 3 has a problem of being pulled down during use.
[0005]
Japanese Patent Application Laid-Open No. 2000-93473 is disclosed as a countermeasure for this problem. The system of the publication has a structure in which a slide fastener is sewn along the longitudinal direction of the cuff, and an extension portion is provided in which the opening / closing start end side of the slide fastener protrudes from the joining end portion of the cuff.
[0006]
[Problems to be solved by the invention]
However, the mounting structure in which the slide fastener is protruded as shown in the above publication is usually used in many bags such as bags, but when this structure is applied to this type of pneumatic massage air bag, Still has the following problems.
[0007]
In other words, since the opening and closing start side of the slide fastener itself protrudes from the cuff, there is a slight difficulty in appearance with the protruding part of the opening and closing start end of the fastener hanging around the cuff. In addition to the hindrance, stress concentrates on the part where the protruding base of the fastener and the cuff are attached, which may lead to fraying of the thread from this part, and there is also a problem in terms of durability of the air bag. .
[0008]
The present invention has been developed in view of the above-described problems, and an object of the present invention is to prevent the slide fastener from dropping down when the bag body having an airtight chamber is expanded and contracted, and to slide the fastener at the time of opening and closing. It is an object of the present invention to provide a pneumatic massager compression tool that is excellent in operability, has a good fixation of a slide fastener, and is excellent in durability.
[0009]

FIG. 5 is a front view of a state in which each compression tool is expanded.
[0012]
As shown in FIGS. 6 and 7, the compression device for a pneumatic massager according to the present invention forms a single bag 10 by superposing two sheet members 10a and 10b and welding the periphery by high-frequency heating means or the like. Furthermore, welding is performed along the short direction to form a plurality of hermetic chambers 11, 12, 13, and 14. Further, a substantially U-shaped cutout portion 15 is formed at the knee, and the overall shape is substantially the same. It is configured to have a leg shape.
[0013]
The outer sheet member 10a and the inner sheet member 10b are non-breathable resin sheets, and the material is appropriately selected from synthetic resins such as urethane resin and polyvinyl chloride resin.
The bag body 10 may be a sheet body having a plurality of airtight chambers covered with a separate cover member, or may have another structure.
[0014]
Further, a slide fastener 16 having a slider 16a is attached to a joint portion in the longitudinal direction of the bag body 10 by sewing or adhesion, and an opening / closing start end 17 of the slide fastener 16 is formed on the bag body 10 as shown in FIG. It is provided at the position of the extended portion 24 where a part of the end portion is extended. That is, part of the end portions of the sheet members 10a and 10b is extended from the welded portion 12a of the hermetic chamber 12 of the bag 10 by a length X that is larger than the length x of the conventional sheet member 2 shown in FIG. The opening / closing start end 17 of the slide fastener 16 is disposed at the above position, and an end region 18 for preventing the slide fastener 16 from being pushed downward by the component force F generated at the boundary of the slide fastener 16 when the bag body 10 is inflated. Provided.
[0015]
Next, FIG. 3 and FIG. 5 are compression tools for wearing on the arm and massaging, and this compression tool has the same structure as that mounted on the above-mentioned leg, but the overall shape Is formed in a substantially arm shape.
[0016]
This arm compression tool has a length that is larger than the length y of the conventional sheet member 2 shown in FIG. 12 from the welded portion 11a of the airtight chamber 11 of the bag body 10 to the entire end portion of the sheet members 10a and 10b. The opening / closing start end 19 of the slide fastener 16 is disposed at the position of the extended portion 24 extended by Y , and the slide fastener 16 is pushed downward by the component force F generated at the boundary of the slide fastener 16 when the bag body 10 is inflated. An end region 20 is provided to prevent the damage.
Note that the lengths x and y in FIGS. 8 to 12 are the distances to the welded portion provided in the hermetic chamber intersecting with the length direction of the slide fastener, and this length is the outer circumference of a normal bag body. X or y is the distance between the welded portion and the outer peripheral edge of the bag.
[0017]
Further, as shown in FIG. 1, a compressed air inlet / outlet port 21 and a compressed air supply source (compressor) 22 provided in each of the airtight chambers 11, 12, 13, and 14 of the bag body 10 are connected via an air hose 23. ing.
[0018]
Next, the operation of the above embodiment will be described. In use, as shown in FIG. 1, a pressure tool is wrapped around a leg or an arm, and the bag body 10 is attached with a slide fastener 16.
When the compressed air supply source 22 such as a compressor is driven, the airtight chambers 11 to 14 connected with the air hose 23 sequentially perform effective massage for promoting blood circulation while repeating expansion and contraction.
[0019]
At this time, since the opening / closing start ends 17 and 19 of the slide fastener 16 are provided at positions where all or part of the end of the bag body 10 is extended, the slide fastener 16 is expanded when the bag body 10 is expanded as shown in FIG. End regions 18 and 20 are provided to prevent the slide fastener 16 from being pushed downward by the component force F generated at the boundary 16. Accordingly, the expansion force of the bag 10 and the hermetic chambers 11 to 14 acts in the direction of lowering the slide fastener 16 than in the direction of lowering the slide fastener 16, so that the slide fastener 16 works in the closing direction. Without acting in the opening direction, there is no risk of pulling down.
[0020]
In addition, after the use is finished, the end of the bag body 10 is picked with a finger, and the slider 16a of the slide fastener 16 is pulled down as it is, so that the bag body 10 can be reliably removed from the massage parts such as legs and arms. The operability is extremely simple and the opening / closing start ends 17 and 19 of the slide fastener 16 protrude from the bag body 10 as protruding pieces, so that the product design is not impaired.
