Description

  The present invention relates to a massage device for inflating and deflating a blow-molded air bag to give massage stimulation to a human limb or the like.

  Conventionally, an air bag (air bag) that is placed on the back of a chair and massages the waist, etc., is a blow-molded product, and the air bag is inflated and contracted as air is supplied and exhausted by an air supply / exhaust device. An air massage device that gives massage stimulation is known (see, for example, Patent Document 1).

The air bag described in Patent Document 1 is contracted so that both side surfaces of the air bag are parallel to each other at a predetermined interval as the air is discharged, and is positioned on the front side with air supply. The side of the side is mainly inflated to press the waist of the human body leaning on the backrest.
JP 2004-129786 A (paragraphs 0014-0019, 0026-0035, FIGS. 1 to 4)

  In the case of a conventional blow-molded air bag, when the side surface located on the front side that was in a flat state is inflated with the air supply to the air bag, the air bag is inflated so that the center part of the side surface protrudes most. And Thereby, the said center part presses a human body most strongly, and the pressing force with respect to a human body becomes weak, so that the circumference | surroundings of an airbag are approached from the said center part.

  For this reason, it is unsuitable for giving surface stimulation to the treatment part of a human body. When massaging the limbs of the human body, such as the legs, especially the lower leg with an inflating / deflating air bag, pressing the lower leg with an area approximately equivalent to the size of the airbag to provide surface stimulation to the lower leg can promote blood flow in the leg. Therefore, it is known that it is effective in promoting blood circulation throughout the body. However, even if the structure of massaging the lower leg using the airbag described in Patent Document 1 is not a surface stimulus, the blood circulation promotion effect cannot be obtained.

  Furthermore, in a conventional blow molded product air bag, the portion corresponding to the central portion of the air bag intensively presses the treatment portion, and there is a risk that the treatment portion will be painful due to excessive pressing.

  The objective of this invention is providing the massage device which can give a strong press irritation | stimulation partially while giving a surface irritation | stimulation as a whole to a treatment part, and can massage.

In order to solve the above-described problems, the present invention provides a base having a groove wall formed with a treatment groove in which a treatment portion of a human body can be taken in and out, and a treatment portion which is disposed in the treatment groove and is expanded and contracted by an air supply / exhaust device. The air bag is made of a blow molded product that gives massage stimulation to the bag, and the air bag protrudes toward the back of the bag so as to be along the back of the bag supported by the groove wall of the base and the side of the treatment area. A compression surface portion having a curved shape, and the compression surface portion is formed of an uneven portion provided extending in the longitudinal direction of the groove wall at the center portion thereof and an arc-shaped portion continuous on both sides of the uneven portion, and The thickness of the pressing surface portion is characterized in that the concavo-convex portion is the thinnest and the arc-shaped portion gradually becomes thicker as the arc-shaped portion and the bag back surface portion become closer to the wall surface portion that is continuously integrated.

  According to the present invention, it is possible to give a surface stimulus to the treatment portion with the curved compression surface portion of the blow molded product air bag, and a strong pressing stimulus is partially applied to the treatment portion with the uneven portion of the compression surface portion. A massage device that can be given and massaged can be provided.

  An embodiment of the present invention will be described with reference to FIGS.

  Reference numeral 1 in FIG. 1 denotes a chair-type massage machine, and the massage machine 1 includes a chair body 2 and a massage device 21 for a human limb, for example, the lower leg.

  The chair body 2 includes a seat portion 3, armrest portions 4 provided on both sides in the width direction of the seat portion 3, and a backrest portion 5 that is preferably attached to the rear side of the seat portion 3 so as to be reclining. . The backrest 5 includes, for example, a pair of lower waist massage air bags 6, a pair of waist massage air bags 7, and a pair of means for massaging the user's upper body seated on the chair body 2. A back massage air bag 8 and a pair of shoulder massage air bags 9 are attached. In addition, the code | symbol 10 in FIG. 1 has shown the backrest part cover which consists of the cloth | dough which has the elasticity which covered the air bags 6-9 and was attached to the backrest part 5. FIG.

  These air bags 6 to 9 are inflated and contracted in a desired mode as they are selectively supplied and exhausted with the driving of an air supply / exhaust device 11 disposed in a space below the drive source, for example, the seat portion 3. Then, apply massage with compression / relaxation to the entire upper part of the seated person or a selected part. Instructions on various massage operations such as driving and stopping of the air supply / exhaust device 11, designation of a massage location, mode selection, and the like can be given by an operation unit, for example, a remote controller 12 shown in FIG. 1 as a preferred example.

  In the present invention, the massage means of the chair body 2 can be omitted. However, when the massage means is provided in the chair body 2, mechanical massage means for giving massage stimulation to the upper body of the seated person using so-called kneading balls may be provided instead of the air-type massage means described above. In addition to the backrest 5, it is also possible to provide an additional massage means such as an air type in the seat 3.

  The air supply / exhaust device 11 also serves as a drive source for the massage device 21. The massage device 21 is, for example, on the seat portion 3 of the chair body 2, a position standing substantially vertically as shown in FIG. 1 centering on a pivot (not shown), and a position protruding slightly forward and downward in front of the seat portion 3. It is provided so that it can be positioned at any position between these positions and both positions. The massage device 21 includes the air supply / exhaust device 11, the base 22 shown in FIGS. 2 to 4, massage air bags 27 and 28, and an exterior cover 35.

  The base 22 includes a groove wall that forms a treatment groove in which a lower leg, which is a treatment portion of a human body, can be taken in and out. Specifically, as shown in FIG. 2, the groove wall includes, for example, a pair of first support walls 23, a second support wall 24 provided therebetween, a corresponding first support wall 23 and a first support wall 23. The two support walls 24 are formed so as to have a bottom wall 25 that is integrally continuous. The first support wall 23 and the second support wall 24 form a groove side wall portion of the groove wall and extend in parallel to each other. A treatment groove 26 is formed by the first support wall 23, the second support wall 24, and the bottom wall 25 therebetween. A seated person's lower leg (indicated by reference sign B in FIGS. 3 and 4) can be taken in and out of the pair of treatment grooves 26.

  The air bag 27 is obtained by blow-molding a synthetic resin such as a polyethylene resin. As shown in FIG. 2, the air bag 27 is inflated and contracted by air supply and exhaust, and a peripheral portion of the bag portion 27a. It is formed from the attachment part 27b extended integrally from. Similarly, the air bag 28 is also obtained by blow molding a synthetic resin such as a polyethylene resin, and is integrally formed from a hollow bag portion 28a that is inflated and contracted by air supply / exhaust and a peripheral portion of the bag portion 28a. It is formed from the extended attachment part 28b.

  The bag portions 27a and 28a of the air bags 27 and 28 have a bag back surface portion 29 and a compression surface portion 30 facing the bag back surface portion 29. These bag portions 27 a and 28 a are communicated with the air supply / exhaust device 11, and are expanded and contracted in synchronization by being supplied and exhausted by the air supply / exhaust device 11. As shown in FIG. 2, a plurality of mounting portions 27b and 28b are provided, for example, two each, and these are strip-shaped non-inflatable portions having flexibility.

  The air bags 27 and 28 are attached to the base 22 so that the lower leg B placed in the bottom wall 25 can be compressed from the side. That is, as shown in FIG. 3 and FIG. 4, one air bag 27 is fixed to the bottom wall 25 with the attachment portion 27 b with a stopper 33 such as a screw, so that the bag back surface portion 29 is fixed to the first support wall 23. It is attached along the side surface 23a on the treatment groove 26 side. The other air bag 28 is fixed to the bottom wall 25 with a stopper 34 such as a screw so that the back surface portion 29 of the other air bag 28 extends along the side surface 24a of the second support wall 24 on the treatment groove 26 side. Installed. The side surfaces 23a and 24a are inclined in opposite directions. As a result, the treatment grooves 26 on both sides of the second support wall 24 are formed so that the width gradually becomes narrower toward the bottom wall 25 so that the lower leg B can be easily taken in and out.

  As shown in FIG. 2, in this embodiment, two air bags 27 and two air bags 28 are provided in the direction in which the treatment groove 26 extends so that the kneecap side portion and the ankle side portion of the lower leg can be massaged individually. Although arranged in parallel, this may be one, or three or more. The air bags 27 and 28 arranged corresponding to the width direction of the base 22 have the same size.

  The compression surface portions 30 of the air bags 27 and 28 have a curved shape that is convex toward the bag back surface portion 29 as a whole. This curved shape is, for example, a curved shape along the side surface of the lower leg B corresponding to the shape of the treatment part of the human body. A part of the compression surface portion 30, for example, a central portion in the vertical direction, is provided with a plurality of concave and convex portions 30 a that are continuous with each other in the direction in which the lower leg B is taken in and out of the treatment groove 26. Therefore, the curved compression surface portion 30 is formed by the uneven portion 30a and the arc-shaped portions 30b and 30c on both sides thereof. 3 and 4, one arcuate portion 30b is integrally continuous on the upper side of the uneven portion 30a, that is, in a direction away from the bottom wall 25, and the other arcuate portion 30c is on the lower side of the uneven portion 30a, In addition, it is continuously integrated in the direction approaching the bottom wall 25.

  The concavo-convex portion 30 a is formed by projecting the convex portion toward the bag back surface portion 29. Furthermore, the concavo-convex portion 30 a extends along the longitudinal direction of the first support wall 23 and the second support wall 24 as shown in FIG. 2. In the present embodiment, the concavo-convex portion 30a is provided with both ends of the recess open to the wall portions before and after the air bag 27 or 29, but the both ends of the recess may not be open. The concavo-convex portion 30a is preferably provided on a part of the compression surface portion 30 so as to substantially correspond to the side pot of the lower leg B.

  3 and 4, reference numeral 30 d denotes a first wall surface portion of the peripheral wall in which the arc-shaped portion 30 b and the bag back surface portion 29 are continuously integrated, and reference numerals 30 e in FIGS. 3 and 4 indicate the arc-shaped portion 30 c and the bag back surface. The 2nd wall surface part is shown among the surrounding walls which connected the part 29 integrally. Between the arc-shaped portion 30b and the first wall surface portion 30d, the arc-shaped portion 30b gradually becomes narrower as it approaches the first wall surface portion 30d, and similarly, the space between the arc-shaped portion 30c and the second wall surface portion 30e is reduced. As the arcuate portion 30c approaches the second wall surface portion 30e, it gradually becomes narrower. Therefore, as for the thickness of the compression surface portion 30 of the air bags 27 and 28 made of blow molded products, the uneven portion 30a is the thinnest, and the arc-shaped portions 30b and 30c on both sides gradually approach the wall surface portion 30d or the wall surface portion 30e. It is formed thick.

  The exterior cover 35 is formed of a stretchable fabric or the like. As shown in FIGS. 3 and 4, the exterior cover 35 is covered with the base 22 by covering the air bags 27 and 28 and the treatment groove 26. The groove cover portion 35a of the exterior cover 35 that covers the treatment groove 26 is recessed along the shape of the treatment groove 26 so as not to prevent the insertion of the lower leg B into the treatment groove 26. The groove cover portion 35a The air bags 27 and 28 can move following the expansion and contraction.

  When the massage device 21 is not driven, the air bags 27 and 28 are in a contracted state. In this state, as shown in FIG. 3, the bag back surfaces 29 of the air bags 27 and 28 have a planar shape and are in surface contact with the side surface 23 a of the first support wall 23 or the side surface 24 a of the second support wall 24. It is arranged at the standby position. As a result, a sufficient space is formed between the air bags 27 and 28 to allow the seated person's lower leg B, which is the treatment portion, to be taken in and out of the treatment groove 26.

  Then, the massage device 21 drives the air supply / exhaust device 11 by the remote controller 12 with the lower leg B inserted in the treatment groove 26 to expand and contract the air bags 27 and 28 corresponding to the width direction of the base 22. The lower leg B is massaged by repeating simultaneously. In this massage, the state in which the air bags 27 and 28 are inflated is shown in FIG. 4, and the state in which the air bags 27 and 28 are contracted is shown in FIG. When the air bags 27, 28 located on both sides of the lower leg B are inflated, the lower leg B is compressed from the side, and when the air bags 27, 28 are contracted, the air pressure is applied to the lower leg B from the side. Is released and the lower leg B relaxes.

  When the air bags 27 and 28 are inflated by the supply of air, the bag back surface portion 29 is deformed so as to protrude toward the side surface 23 a of the first support wall 23 or the side surface 24 a of the second support wall 24. In other words, the peripheral portion of the bag back surface portion 29 is deformed so as to be separated from the side surface 23 a of the first support wall 23 or the side surface 24 a of the second support wall 24. For this reason, the air bags 27 and 28 are brought close to each other. As a result, the pressure surface portions 30 of the air bags 27 and 28 are arranged so as to be pressed against the side surfaces of the lower leg B via the exterior cover 35, and the lower leg B is sandwiched between the air bags 27 and 28.

  Since the compression surface portion 30 has a curved shape corresponding to the side surface of the lower leg B in advance, not only the uneven portion 30a in the central portion but also the arc-shaped portions 30b and 30c on both sides thereof are inflated with the inflation of the air bags 27 and 28. It is pressed against the side of the lower leg B. That is, most of the pressing surface portion 30 is pressed so as to come into surface contact with the side surface of the lower leg B.

  In such a surface contact state, as the internal pressure of the air bags 27 and 28 increases, the surface contact pressure to the side surface of the lower leg B of the compression surface portion 30 increases, and the unevenness that is easier to deform than the arcuate portions 30b and 30c due to the internal pressure. The portion 30a strongly presses the lower leg B.

  Although the air bags 27 and 28 made of blow-molded products are inflated and contracted to massage the lower leg B, when the air bags 27 and 28 to be inflated and inflated are inflated, the area of most of the compression surface portion 30 is increased. While pressing the lower leg B in the treatment groove 26 and applying a surface stimulus with a compression area corresponding to the pressure area, a partial strong pressing stimulus is applied to the lower leg B of the left and right air bags 27, 28. A massage can be performed in a state of being wrapped by the compression surface portion 30.

  Therefore, as the surface stimulation of the size substantially corresponding to the size of the air bags 27 and 28 is given to the lower leg B, the blood flow of the legs is promoted, and as a result, the circulation of the whole body can be promoted. In such surface stimulation, the pressed points do not concentrate locally, so that excessive pressing can be prevented from causing pain to the lower leg B. Furthermore, although it is known that it is easy to get used to the stimulation by surface stimulation alone and that the lack of stimulation is sensed, it is known that, as described above, strong pressing stimulation locally at the concavo-convex portion 30a simultaneously with the surface stimulation. Is applied to the lower leg B, it is possible to suppress habituation to massage stimulation in terms of bodily sensation even though surface stimulation is applied. In addition, as described above, since the local pressure stimulation by the uneven portion 30a is made in the area of the surface stimulation, the lower leg is compared with the case where the uneven portion 30a alone is pressed without the surface stimulation. There will be no excessive pressure that causes pain to B.

  Moreover, the pair of air bags 27 and 28 having the curved compression surface portion 30 massage the lower leg B from both sides in the width direction as described above, so that the compression surface portion 30 has the lower leg B in the treatment groove 26. In the state pressed against the lower leg B, the lower leg B is wrapped in the circumferential direction by the compression surface portion 30 of the air bladders 27 and 28. As a result, the angular portion formed by the arc-shaped portion 30b away from the bottom wall 25 and the first wall surface portion 30d that continues to be bent is positioned so as to cover the front portion of the lower leg B.

  Therefore, the lower leg B, which is lighter than the upper body, the buttocks, etc., is moved upward in FIG. 4, that is, in the direction of coming out of the treatment groove 26 while being away from the bottom wall 25 as the air bags 27 and 28 expand. Therefore, the lower leg B can be reliably massaged while being held in a predetermined position.

  The present invention is not limited to the one embodiment. For example, a massager can be used separately from a main support such as a chair body that mainly supports a user's body, such as a chair body, and can be used in parallel with the main support. It can also be implemented as a massager that massages the lower leg or upper limb of the human body exclusively regardless of the support.

  Moreover, you may arrange | position the air bag which massages the treatment parts, such as a limb body, corresponding to one side instead of the both sides of a treatment part. For example, in the case of the configuration of the one embodiment, it is possible to carry out without providing an air bag on the side surface 24a of the second support wall (groove wall) 24. In this case, when the air bag 27 is inflated, a cushioning material such as foamed urethane resin is attached to the side surface 24a of the second support wall 24 to prevent the lower leg B from escaping in the inflation direction. It is preferable to reduce the contact between the first support wall 24 and the second support wall 24.

  Moreover, this invention is not restrict | limited to the massage only of a limb. For example, the back of the chair body is used as a base, and a groove wall is formed in the lower part of the back (base) to form a treatment groove into which the seated person's waist can be put in and out. An air bag made of a blow molded product having a bag back surface portion and a curved compression surface portion convex toward the bag back surface portion is disposed, and the air bag is supplied and exhausted by an air supply / exhaust device connected thereto. It can also be applied to a massager that massages the waist of the seated person by expanding and contracting. In this case, the compression surface portion may be provided over both the waist portions of the seated person or in correspondence with one waist portion, and the uneven portion may be provided at a position corresponding to the urn of the waist portion.
