[0014]
DETAILED DESCRIPTION OF THE INVENTION
  Hereinafter, referring to FIG. 1 and FIG.First reference exampleWill be explained.
[0015]
  Figure 1First reference exampleIt is sectional drawing which shows the structure of the massage tool with the air supply / exhaust means which concerns on this, Comprising: This massage tool was developed as a massage tool for limbs, especially both legs.
[0016]
  The massage tool body 3 included in the massage tool 1 is formed of an upper case member 3a having a lower surface opened, and a lower case member 3b connected to the member 3a by closing the opened lower surface. On the upper surface of the upper case member 3a, a pair of treatment grooves 4 opened to the upper surface are formed in parallel with each other. These treatment grooves 4 consist of inverted trapezoidal recesses that gradually increase in width as they approach the upper surface of the upper case member 3a, and are also open to both the front and rear surfaces of the upper case member 3a. Therefore, a treatment part such as a user's lower limb can be taken in and out of both treatment grooves 4 from above.
[0017]
  Each of the treatment grooves 4 covers the inclined groove side wall 4a individually and is firstAir bag5 are provided. eachAir bagReference numerals 5 denote the same size, and upper end portions thereof project obliquely from the upper surface of the upper case member 3a. In FIG. 1, a pair of first elements arranged on both sides in each treatment groove 4 are shown.Air bagAlthough 5 showed what was mutually independent, it replaced with this and a pair of 1st in the treatment groove | channel 4 was carried out.Air bag5 may be integrally formed through a non-inflatable portion disposed so as to cover the upper surface of the bottom wall 4 b of the treatment groove 4. First of eachAir bagThe air supply / exhaust port 5a of 5 is penetrated through the groove side wall 4a and protrudes into the massage tool body 3, and a first air hose 6 forming a first air supply / exhaust path is provided in each of the air supply / exhaust ports 5a. Connected individually. These first air hoses 6 have the same diameter and the same length.
[0018]
  Back housings 8 that form storage chambers 7 between the bottom walls 4b of the treatment grooves 4 are screwed to the bottom walls 4b. Each of the pair of storage chambers 7 has a secondAir bag9 and the presser 10 are accommodated. SecondAir bag9 is disposed at the bottom of the storage chamber 7, and the pressing member 10 placed on the back 9 has at least one central portion of the upper surface of the base 10 a that is moved in the vertical direction with the inner surface of the storage chamber 7 as a guide. The pressing protrusion 10b is formed to protrude upward. And the press protrusion 10b penetrates the width direction center part of the said bottom wall 4b, and is protruded inside the bottom part of the treatment groove | channel 4, and 2ndAir bag9 is moved up and down with the expansion and contraction. Second of eachAir bagThe air supply / exhaust port 9a of 9 is penetrated through the back housing 8 and protrudes into the massage tool body 3, and the second air hose 11 forming the second air supply / exhaust path is individually connected to the air supply / exhaust port 9a. Has been.
[0019]
  As representatively shown in FIG. 2, the second air hose 11 includes a hose portion 11 a having the same diameter as the first air hose 6 and a throttle tube 11 b interposed in an intermediate portion of the hose portion 11 a. The inner diameter of the throttle tube 11b is smaller than the inner diameter of the hose portion 11a.Air bag11 is firstAir bag5 is used as a flow path resistance portion which constitutes a time difference expansion means for expanding with a certain time delay.
[0020]
  Control means 12 and air supply / exhaust means 13 are accommodated in the massage tool body 3. The control means 12 for controlling the operation of the air supply / exhaust means 13 is a combination of various electric components such as a CPU and a memory, and a remote control device 14 disposed outside the massage tool body 3 includes a remote control device 14. Connected via lead wires. The remote control device 14 is used to arbitrarily select and designate various massage modes preset in the control means 12.
[0021]
  The air supply / exhaust means 13 includes an air pump 15, a distribution pipe 17 connected to the discharge port of the pump 15 via an air hose 16, and an exhaust side end of the distribution pipe 17. And an exhaust valve 19 connected via an air hose 18. The air pump 15 has a surge tank for absorbing pulsation, etc., is used to generate compressed air and supply it to the distribution pipe 17, and an exhaust valve 19 made of an electromagnetic valve is opened. It is provided for discharging the air in the distribution pipe 17 by operation. The distribution pipe 17 includes the first and second pipes.Air bagThe number of air supply / exhaust ports 17a corresponding to 5..., 9.Air bagThe first and second air hoses 6, 11, which are communicated with 5, 9, are individually connected.
[0022]
  Next, in order to use the massage device 1 having the above-described configuration, first, the massage device 1 connected to the power source is moved to the lower limb side of the user, and both lower limbs of the user are placed in the pair of treatment grooves 4. It is housed and set from above so that it can be passed individually. Next, the user may give necessary operation instructions via the remote control device 14.
[0023]
  Then, the air supply / exhaust means 13 intermittently operates the air pump 15 according to the designated massage mode and opens / closes the exhaust valve 19, so that the air supply / exhaust means 13 is guided through the air hose 16 each time the air pump 15 is operated. The compressed air is distributed in the distribution pipe 17, and the first air is passed through each first air hose 6.Air bag5 and the second air hose 11 through the second air hose 11, respectively.Air bag9 is sent to each. Further, since the exhaust valve 19 is opened during the period when the operation of the air pump 15 is interrupted, the first and secondAir bagThe air that flows out from the air outlets 5 and 9 is discharged from the exhaust valve 19 through the air hose 18.
[0024]
  Thus eachAir bag5 and 9 repeat the operation of expanding when air is supplied and contracting when air is exhausted. As a result, the firstAir bagNo. 5 is a massage that presses the lower limbs from both sides and relaxes and releases the lower limbs to release the massage.Air bag9 presses the back side of the lower limb through the presser 10 rising from below and releases the back side to relax the back side of the lower limb for massage.
[0025]
  Thus, a pair of first in the treatment groove 4Air bagThe user's lower limbs set in the treatment groove 4 can be massaged from both sides in the width direction along with the expansion / contraction of 5 and the firstair -BagSecond between 5Air bag9, the lower limb set in the treatment groove 4 can be massaged by pressing from the bottom side of the treatment groove 4 and relaxing by releasing it. That is, it is excellent in that the lower limbs can be massaged from three directions at the same time. In addition, since such massage is performed for each of the pair of treatment grooves 4, it is excellent in that the lower limbs of both legs of the user can be massaged at the same time.
[0026]
  And secondAir bagIn conjunction with the expansion / contraction of 9, the pressing element 10 moves in the direction of coming into contact with and separating from the back side of the lower limb set in the treatment groove 4, and the pressing protrusion 10 b massages the lower limb from the back side. Can be pressed firmly against the area to be massaged. Therefore, it is excellent in that the massage from the bottom side of the treatment groove 4 can be strengthened.
[0027]
  And, as mentioned above,Air bagSince massage can be performed by repeating the expansion and contraction of 9, it is not necessary for the user to stand and put weight on the massage tool like a bamboo bamboo stepping. Therefore, while the user is sleeping or sitting, the lower limbs can be set in the treatment groove 4 and used, and if the user sits down on a chair and sets the toe portion of the lower limb in the treatment groove 4, You can massage from the three directions as described above. In this way, the usage posture is rarely restricted, so that usability can be improved. In particular, when sitting on a chair and using the legs of the legs of both legs set in the treatment groove 4,Air bag9 can be effectively massaged by strongly stimulating the pots of each part of the sole through the presser 10 in accordance with the expansion and contraction.
[0028]
  Further, the secondAir bagWhen the compressed air is supplied to and exhausted from the air inlet 9, the throttle tube 11 b of the second air hose 11 communicated with the back 9 serves as a flow path resistance and restricts the flow of air flowing through the second air hose 11. Therefore, in the simultaneous massage from the three directions, the firstAir bagSince the air easily passes through the first air hose 6 that communicates with the first air hose 6 and has a lower flow resistance than the second air hose 11.Air bagFirst prior to 9 expansionAir bag5 expands. In other words, the firstAir bag2 after the expansion of 5Air bag9 begins to expand.
[0029]
  As a result, the first that started to expand firstAir bag5 squeezes the lower limb from both sides in the width direction.Air bag5, the lower limb is held in the treatment groove 4, the secondAir bag9 is inflated to compress the back side of the lower limb from the bottom side of the treatment groove 4, so that the lower limb set in the treatment groove 4 is prevented from easily escaping upward in the compression from the bottom side and strongly presses the lower limb. it can. Therefore, the massage from the bottom side of the treatment groove 4 to the back side of the lower limb can be performed more effectively.
[0030]
  In addition, as described above, the first and second with a time differenceAir bag5 and 9 is realized by providing the second air hose 11 with a throttle tube 11b that increases its flow resistance, so that a rotary valve and its drive unit and a control circuit therefor can be obtained in order to obtain the time difference. do not need.
[0031]
  Therefore, although the massage device body 3 includes the control means 12 and the air supply / exhaust device 13, the storage space for them is small, and the size of the massage device body 3, and thus the entire massage device 1, is small. Excellent in that it can be made. In particular, when the air pump 15 and the exhaust valve 19 of the air supply / exhaust means 13 and the control means 12 are arranged outside the massage tool main body 3, the occupied space of the distribution pipe 17 occupying the main body 3 is a rotary valve. Since the amount of the massage device 1 is less than that of the housing structure, the entire massage tool 1 can be made smaller. In addition, as described above, the rotary valve, its driving unit and the control circuit therefor are not required, so that the structure is simple and can be obtained at low cost. The distribution pipe 17 that distributes the compressed air has no movable part and has a very simple structure. Therefore, even if such parts are employed, the cost does not increase.
[0032]
  In addition, thisFirst reference example, The second air hose 11 is provided with a throttle tube 11b. Instead, the entire second air hose 11 is formed by a throttle tube (hose) thinner than the first air hose 6.May be.Even in this way, the firstAir bag2nd after the expansion of 5Air bag9 can be expanded to obtain the effects as described above.
[0033]
  FIG. 3 illustrates the present invention.Second reference exampleIs shown. thisReference exampleIs basically saidFirst reference exampleSince the configuration is the same as the above,First reference exampleThe description of the configuration and operation thereof will be omitted, and different parts will be described below.Second reference exampleButFirst reference exampleThe difference is the time difference expansion means.
[0034]
  That is, thisSecond reference exampleThe time difference expansion means in the secondAir bag9, the second air hose 111 is communicated with the entire air hose 111. Specifically, the second air hose 111 is longer than the first air hose 6. In this case, the inner diameter of the second air hose 111 may be the same as the inner diameter of the first air hose 6, but it is excellent in that the time difference can be ensured more reliably by making the diameter smaller. The configuration other than the points described above is the above-described configuration.First reference exampleIs the same.
[0035]
  thisSecond reference exampleSecond inAir bagFor the supply and exhaust of compressed air to 9Air bagSince the second air hose 111 communicated with 9 is longer than the first air hose 6, in the simultaneous massage from the three directions, the air passing through the short first air hose 6 communicates with this hose 6. FirstAir bag5 is connected to the long second air hose 11 in the secondAir bagBecause it reaches faster than 9, the secondAir bagFirst prior to 9 expansionAir bag5 expands. In other words, the firstAir bag2 after the expansion of 5Air bag9 begins to expand.
[0036]
  Thereby, saidFirst reference exampleSimilarly to the massage from the three directions, the lower limb set in the treatment groove 4 is prevented from easily escaping upward by the pressure from the bottom side of the treatment groove 4, and the back side of the lower limb is pressed through the presser 10. It can be strongly squeezed. Therefore, the pressure from the bottom side of the treatment groove 4 on the back side of the lower limb can be more effectively performed. In addition, as described above, the first and second time differences are added.Air bagSince the first and second air hoses 11 are made different in length to inflate 5 and 9, a rotary valve and its driving unit and a control circuit therefor are required to obtain the time difference. The whole massage device 1 can be made small, the structure is simple, and the cost is low.Can be obtained.

The inner diameters of the exhaust pipe portion 212a and the exhaust pipe 213 are both larger than the inner diameter of the throttle pipe 11b. An electromagnetic exhaust valve 214 serving as a quick exhaust means is connected to the tip of the exhaust pipe 213. The exhaust valve 214 that normally maintains a closed state is controlled to be opened and closed simultaneously with the exhaust valve 19 by the control means 12. The configuration other than the points described above is the above-described configuration.First reference exampleIs the same.
[0038]
  By the way,First reference exampleIn the configuration of the secondAir bag9 firstAir bagSince the throttle tube 11b is provided in the second air hose to inflate with a time difference with respect to 5, the second inflatedAir bagThe air that is about to be discharged from 9 is difficult to escape due to the flow resistance in the throttle tube 11b, and therefore the air is rapidly discharged and contracts in a very short time.Air bag2 compared to 5Air bagSince 9 contracts gradually, there is a tendency that the feeling of irritation to the treatment site accompanying this contraction is weak.
[0039]
  But thisFirstIn the embodiment, the quick exhaust valve 214 is connected to the second air hose 211, and the valve 214 is opened when the operation of the air pump 15 is interrupted.Air bag9 can be quickly discharged to the outside through the quick exhaust valve 214 without passing through the throttle valve 11b (flow path resistance portion) forming the flow path resistance portion of the second air hose 211. SecondAir bag9 by rapidly releasing the air in the air into the atmosphere.Air bag9 firstAir bagSimilarly to 5, it can be rapidly contracted. Therefore, the secondAir bagThe treatment portion pressed through the presser 10 by the expansion of 9 can be quickly relaxed to enhance the stimulation of the massage from the bottom side of the treatment groove 4 and make the massage more effective. In particular, thisFirstAs in the embodiment, the quick exhaust valve 214 is connected to the throttle tube 11b and the secondAir bag9 to connect with thisAir bagIn the point that it is easy to pull out the air in 9 more rapidlyAre better.
  FIG. 6 shows the present invention.SecondAn embodiment is shown. This embodiment is basically the same as that described above.First reference exampleSince the configuration is the same as the above,First reference exampleThe description of the configuration and operation thereof will be omitted, and different parts will be described below.SecondThe embodiment isFirst reference exampleThe different part is the expanded secondAir bagA quick exhaust means for rapidly discharging air from the second air hose is provided in communication with the second air hose.
[0040]
  That is, thisSecondIn the embodiment, the second air hose 311 forming the second air supply / exhaust path includes a hose portion 11a, a first joint pipe 312 connected to the tip, a throttle pipe 11b connected to the joint pipe 312, The throttle tube 11b and the secondAir bag9 and a second joint pipe 313 provided between them. Exhaust pipe portions 312a and 313 are branched from the first and second joint pipes 312 and 313, respectively. A bypass pipe 314 that bypasses the throttle pipe 11b is connected across the branch pipe sections 312a and 313a, and an electromagnetic on-off valve 315 as a quick exhaust means is provided at an intermediate portion of the pipe 315. . The on-off valve 315 that normally maintains the closed state is controlled to be opened / closed simultaneously with the exhaust valve 19 by the control means 12. The inner diameter of each of the tubes 312 to 314 is thicker than the inner diameter of the throttle tube 11b, and the first air hoseInner diameterIs the same. In addition, the configuration other than the points described above includes the parts not shown in the drawings.First reference exampleIs the same.
[0041]
