Below, the air massage machine of this invention is demonstrated in detail based on one Embodiment shown on drawing.
FIG. 1 is a perspective view showing an embodiment of the air massage machine of the present invention, FIG. 2 is a use state diagram showing an embodiment of the air massage machine of the present invention, and FIG. 3 is an air massage machine of the present invention. FIG. 4 is an explanatory view showing an embodiment of a method for attaching an inflatable bag, a connecting member, and an air hose provided in the air massage machine of the present invention. 5 and 6 are explanatory views showing an embodiment of a connecting member inserted and connected to a supply / exhaust port portion of an inflating and deflating bag provided in the air massage machine of the present invention, and FIGS. 7 to 9 are air massage machines of the present invention. It is explanatory drawing which shows one Embodiment of the fastening member provided in the expansion / contraction bag of FIG. 10, FIG. 10 thru | or FIG. 12 shows one Embodiment of the strip | belt-shaped fastening member provided in the expansion / contraction bag of the air massage machine of this invention. FIG. 13 is an explanatory diagram showing the air massage of the present invention. It is sectional drawing which shows one Embodiment of the connection / exhaust port part to which the connection member of the expansion / contraction bag provided in FIG. 14 is shown, FIG. 14 thru | or FIG. 16 shows the fastening member of the expansion / contraction bag provided in the air massage machine of this invention. It is sectional drawing which shows one Embodiment of the attached / exhaust opening part, FIG. 17 thru | or FIG. 20 is a reference figure which shows a prior art.

  That is, as shown in the embodiment of FIGS. 1 and 2, the air massage machine of the present invention is inflated and contracted by the air supply / discharge device 11a for supplying and exhausting air and the supply / exhaust from the air supply / discharge device 11a. An inflatable and inflatable bag 2a capable of operating, and an air hose 3a interposed between the inflatable and inflatable bag 2a and the air supply / discharge device 11a to serve as an air vent, This is a massage machine 1a in which the air hose 3a and the expansion / contraction bag 2a are arranged at appropriate positions so that the treatment site can be treated with the expansion / contraction bag.

  The air supply / discharge device 11a is composed of an air compressor, an air distributor, and the like, and is installed inside the massage machine 1a as shown in FIG.

  As shown in the embodiment of FIG. 3, the expansion / contraction bag 2a is provided on one side of the expansion / contraction bag 2a with an expansion / contraction portion 21a that performs expansion / contraction operation by air supply / exhaust, and air is supplied to the expansion / contraction portion 21a. A pipe-shaped supply / exhaust port portion 22a serving as a vent portion for ventilation is provided.

  Further, as shown in FIG. 4, a connecting member 4a having an insertion connecting portion 41a at the start end is interposed between the supply / discharge port portion 22a and the air hose 3a. The connecting portion 6a is configured by connecting the portion 41a and the air supply / exhaust port portion 22a of the inflatable bag 2a.

  By connecting and connecting the air hose 3a communicating with the air supply / discharge device 11a through the connection member 4a to the supply / discharge port portion 22a, the expansion / contraction bag 2a is repeatedly supplied and discharged from the air supply / discharge device 11a. The air can be continuously expanded or contracted, or the expansion can be maintained for a certain period, and then the air can be discharged from the inside.

  As described above, the expansion / contraction bag 2a is required to be flexible and durable with respect to its material, as long as the material is repeatedly expanded and contracted. For example, as the material of the inflatable bag 2a, a soft resin that has flexibility and durability, such as ultra-low density polyethylene, and is easy to mold is suitable. In addition, the supply / discharge port portion 22a of the inflatable bag 2a can be integrally formed using the same material as the inflatable portion 21a.

  Connection of the connection member 4a to the supply / discharge port portion 22a and the air hose 3a is made by inserting pipe-like insertion connection portions 41a and 41a formed at both ends of the connection member 4a into the respective mouth portions. . In addition, the connection member 4a may be integrally formed at the tip of the air hose 3a.

  The insertion connecting portion 41a is formed with an annular protrusion 411a having an outer diameter that is larger than the others at the tip thereof so as not to be easily detached from the respective mouth portions.

  Further, as shown in FIG. 4, the annular protrusion 411a has a trapezoidal shape in a side view in which the outer diameter is gradually increased from the tip, and is easily inserted into the supply / discharge port 22a.

  However, as shown in FIG. 13, the sink portion 221a formed on the inner peripheral surface of the supply / exhaust port portion 22a is merely connected to the supply / discharge port portion 22a by the insertion connecting portion 41a having the annular projection 411a. As shown in FIGS. 5 and 6, a soft soft ring member 412a is fitted around the peripheral portion of the insertion connecting portion 41a to solve the problem. Like to do. That is, the soft ring member 412a can enter the gap of the sink portion 221a and close it.

  FIG. 5 shows an example in which the soft ring member 412a is fitted around the peripheral portion of the insertion connecting portion 41a, and FIG. 6 shows a portion past the annular projection 411a from the tip of the insertion connecting portion 41a. A soft ring member 412a is provided.

  The soft ring member 412a may be formed of soft rubber, for example, as long as the material is soft and airless.

  7 to 9 show that the outer periphery of the connecting portion 6a that connects the insertion connecting portion 41a of the connecting member 4a and the supply / discharge port portion 22a of the inflatable bag 2a is connected to the fastening member 5a and the fastening member 5a. It is the air leak prevention structure of one Embodiment formed by connecting and holding with the latching | locking part 52a which fixes and holds the fastening member 5a.

  In other words, the sink portion 221a of the supply / discharge port portion 22a is closed by tightening the outer periphery of the supply / discharge port portion 22a into which the insertion connecting portion 41a is inserted by the fastening member 5a. In this configuration, the tightening force of the opening 22a with respect to the insertion connecting portion 41a can be arbitrarily increased.

  The fastening member 5a is formed in a cylindrical shape and is formed with a locking portion 52a having a tapered shape in cross section, the inner diameter of which can be moved in the length direction of the supply / discharge port portion 22a. Increases and holds the tightening force of the supply / discharge port portion 22a with respect to the insertion connecting portion 41a.

  Therefore, when the insertion connection portion 41a of the connection member 4a is inserted into the supply / discharge port portion 22a in a state where the fastening member 5a is movably provided in the supply / discharge port portion 22a, the insertion connection portion 41 The annular protrusion 411a formed on the outer periphery pushes the soft supply / discharge port 22a toward the outer periphery, and as a result, the diameter of the peripheral portion of the supply / discharge port 22a located on the periphery of the annular protrusion 411a. However, the fastening member 5a is moved so as to cover the larger portion of the supply / discharge port 22a. At this time, the frictional resistance is small at the extreme end side of the locking portion 52a formed on the inner surface of the fastening member 5a, and the frictional resistance is increased toward the proximal end side.

  Therefore, as the fastening member 5a is moved toward the larger portion of the supply / exhaust port portion 22a, the frictional resistance of the locking portion 52a with respect to the supply / discharge port portion 22a increases and the sliding portion 52a slides. Finally, the outer peripheral surface of the enlarged portion of the supply / discharge port portion 22a is strongly pressed from the outside to the inside, and the sink portion 221a of the supply / discharge port portion 22a in the state shown in FIG. 9 by the locking force of the locking portion 52a. 221a is blocked.

  Normally, when the fastening member 5a is used in a state of being fastened to the supply / discharge port portion 22a, the expansion / contraction operation of the expansion / contraction bag 2a also transmits the operation to the vicinity of the supply / discharge port portion 22a and covers the expansion / contraction bag 2a. If the supply / exhaust port 22a rubs against the outer cover of the massage machine 1a or the peripheral part to which the expansion / contraction bag 2a is attached, or if it is used for a long time in such a situation, the supply / discharge port It is considered that the material deterioration of the portion 22a is caused, so that the closed sink portion 221a may cause a gap and induce air leakage. However, the forms shown in FIGS. In this configuration, the tightening force of the supply / discharge port portion 22a with respect to the insertion connection portion 41a can be arbitrarily increased.

  That is, as described above, since the locking portion 52a having a tapered shape in cross section is formed on the inner diameter of the fastening member 5a, even if the gap of the closed sink portion 221a reappears, the fastening member 5a. The problem can be solved by further moving the lever to further increase the locking force of the locking portion 52a with respect to the supply / discharge port portion 22a.

  In addition, although the said locking part 52a made the base end into the said expansion / contraction part 21a side, and made the extreme end into the said connection member 4a side, it is not restricted to this, While making those base ends and extreme ends reverse, The movement of the fastening member 5a with respect to the supply / discharge port portion 22a is also performed in a direction opposite to the above-described direction, whereby the outer periphery of the supply / discharge port portion 22a can be tightened.

  The fastening member 5a in the form shown in FIGS. 10 to 12 is formed in a band shape, and has an annular locking portion 52a provided on the base end side, and along the length direction on the extreme end side. A plurality of protrusions 51a are provided, and an air leakage prevention structure is provided in which the protrusion 51a on the extreme end side is locked to the locking part 52a on the proximal end side.

  Therefore, the end side is penetrated into the ring of the locking portion 52a of the fastening member 5a and the end side is pulled, and the tightening at the supply / discharge port portion 22a is applied to the inner peripheral surface of the supply / discharge port portion 22a. When the sink portion 221a to be formed is sufficiently closed, the protrusion 51a can be locked to the locking portion 52a.

  Thus, the locking portion 52a retains the tightening force of the supply / exhaust port portion 22a with respect to the insertion connecting portion 41a, and the tightening member 5a allows the tightening force to be arbitrarily set. Therefore, it is possible to cope with the problem of air leakage of the sink portion 221a due to the material deterioration of the supply / exhaust port portion 22a as described above.

  As shown in FIGS. 11 and 12, the fastening of the fastening member 5a at the supply / exhaust port portion 22a is constricted at the rear of the annular projection 411a of the connection member 4a inserted into the supply / discharge port portion 22a. If it is performed at the position corresponding to the portion, the connecting member 4a can be reliably fixed so as not to be unexpectedly detached from the supply / discharge port 22a.

  In the embodiment shown in FIGS. 10 to 12, a plurality of the fastening members 5a are used, and at least the fastening members 5a are configured to be positioned in the front-rear direction in the length direction of the supply / exhaust port portion 22a. .

  Further, the locking position of the fastening member 5a is locked so that the position of the sink part 221a formed on the inner peripheral surface of the supply / discharge port portion 22a closed by the fastening member 5a does not correspond. ing.

  That is, one fastening member 5a is used for one sink part 221a, and the locking part 52a is not located at the outer peripheral position of the supply / discharge port part 22a where the sink part 221a is located. In such a manner, the fastening member 5a is attached to the supply / discharge port 22a.

  Thus, from the state where the insertion connecting portion 41a is connected to the supply / discharge port portion 22a shown in FIG. 13, as shown in FIG. 14, one sink portion 221a on the right inner surface of the supply / discharge port portion 22a is closed. Therefore, one fastening member 5a is fastened to the supply / discharge port portion 22a so that the locking portion 52a is not positioned at the outer peripheral position of the supply / discharge port portion 22a where the sink portion 221a is positioned.

  In the form of FIG. 14, the locking portion 52a of the fastening member 5a is located at the outer peripheral position of the left supply / discharge port portion 22a that is 180 degrees opposite to the sink portion 221a on the right inner surface of the supply / discharge port portion 22a. It is something that is made to come.

  If the locking portion 52a is positioned at the outer peripheral position of the supply / discharge port portion 22a where the sink portion 221a is located, the sink portion 221a on the left inner surface of the supply / discharge port portion 22a as shown in FIG. It will be in the state which opens. Therefore, in order to close the sink part 221a, the locking part 52a must not be positioned at the outer peripheral position of the supply / discharge port part 22a where the sink part 221a is located.

  Next, as shown in FIG. 15, another sink member 221a on the left inner surface of the supply / discharge port 22a is closed using another fastening member 5a. As in the case of FIG. 14, the fastening member 5 a is tightened so that the locking portion 52 a is not located at the outer peripheral position of the supply / discharge port portion 22 a where the sink portion 221 a is located. In the form of FIG. 15, the locking portion 52a of the fastening member 5a comes to the outer peripheral position of the right supply / discharge port portion 22a that is 180 degrees opposite to the sink portion 221a on the left inner surface of the supply / discharge port portion 22a. It is a thing.

  Therefore, in the above-described configuration in which the two fastening members 5a are fastened, as shown in FIG. 15, the respective locking portions 52a are respectively positioned at 180 degrees apart from each other on the outer periphery of the supply / discharge port portion 22a. Become. That is, each locking portion 52a is arranged at a position facing each other on the outer periphery of the supply / discharge port portion 22a, and each sink portion 221a can be effectively closed.

  Note that it is not always necessary that the locking portion 52a of the fastening member 5a is located at the outer peripheral position of the supply / discharge port portion 22a which is 180 degrees opposite to the sink portion 221a, and one fastening corresponding to the sink portion 221a. Any position may be used as long as the locking portion 52a of the member 5a is not located at the outer peripheral position of the supply / discharge port portion 22a where the sink portion 221a is located. For example, FIG. 16 shows that each locking portion 52a of each fastening member 5a comes to a position 90 degrees away from each other on the outer periphery of the supply / discharge port portion 22a.

  The fastening member 5a described above is an example used for the connection between the supply / exhaust port 22a and the connection member 4a. However, the connection member 4a is not limited to this, and also in the connection between the connection member 4a and the air hose 3a. It can be applied.
