(example of the mode that can be adopted by the air massage device)

One embodiment of the air massage device according to the present disclosure includes a wearing article to be worn on a leg. The wearing article includes an upper covering section, a lower covering section, and a connecting section. The upper cover portion can be worn on the leg in any one of a plurality of wearing modes, and comprises an upper air bag capable of massaging the leg, wherein the plurality of wearing modes comprise a first wearing mode worn on the thigh and a second wearing mode worn on the thigh and the lower leg across the knee. The lower covering part is arranged at a position lower than the upper covering part, is worn on the lower leg and comprises a lower air bag capable of massaging the lower leg. The connecting portion connects the upper covering portion and the lower covering portion so that the upper covering portion and the lower covering portion can move relative to each other.

According to the air massage device, the length of the wearing object in the length direction of the leg is different according to the wearing manner. Therefore, the user can select a wearing manner corresponding to the length of the leg of the user to wear the wearing object on the leg. According to the air massage device, the upper air bag and the lower air bag are disposed at positions suitable for massaging the legs, and the air bags can give the legs a desired massage feeling. Thus, the air massage apparatus can appropriately massage the legs in accordance with various body shapes of the user.

[ 2 ] according to an example of the air massage device, when the upper covering portion is worn on the leg in the first wearing manner, the connection portion opens forward so that the knee is exposed.

This makes it possible for the user to easily perform the knee bending operation and the knee stretching operation, and to easily change the posture of the user when using the air massage apparatus.

[ 3 ] according to an example of the air massage device, the wearing article further includes a positioning portion that determines the position of the upper covering portion by contacting the popliteal fossa.

The popliteal fossa belongs to one of the parts that also have characteristic shapes in the leg. The positioning part is targeted at such a popliteal fossa, so that the user can easily wear the wearing article on the leg.

[ 4 ] according to an example of the air massage device, the upper covering section includes: a first upper cover part which is worn on the thigh in the second wearing mode; a second upper covering part which is worn on the lower leg in a second wearing mode; and a connecting portion connecting the first upper covering portion and the second upper covering portion. The upper airbag includes: a first upper bag provided in a portion of the first upper covering portion that covers the front surface of the thighs; and a second upper airbag provided in a portion of the second upper covering portion that covers the back of the lower leg.

According to the air massage device, when the upper cover portion is worn on the leg in the second wearing manner, the periphery of the knee can be massaged by the first upper air bag and the second upper air bag. There are many muscles around the knee that have a high massage effect. Therefore, the air massage device can effectively massage the legs.

The positioning portion includes a convex portion mounted to the massaging popliteal fossa of the third upper bladder.

According to the air massage device, the popliteal fossa is massaged by the convex portion of the positioning portion by the inflation of the third upper air bag. Therefore, an ideal massage feeling can be given to the popliteal fossa.

[ 6 ] an example of the air massage device further includes: an air pump which supplies air to the upper air bag and the lower air bag; a first hose that connects the upper airbag and the air pump, is drawn out from a position on the upper covering portion that is on the outer side or the inner side of the center of the leg in the width direction, and is disposed so as not to cross the center of the leg in the width direction; and a second hose that connects the lower air bag and the air pump, is drawn out from a position on the outer side or the inner side of the lower covering portion with respect to the center in the width direction of the leg, and is disposed so as not to cross the center in the width direction of the leg.

According to the air massage apparatus, when a user wearing a wearing object sits on a chair, the respective hoses are not easily sandwiched between the legs and the chair. In addition, the hoses are not easily pinched between the legs and the ground when the user wearing the wearing article sits on the ground. Therefore, the user does not easily feel a sense of incongruity.

[ 7 ] according to an example of the air massage device, the wearing article further includes: a foot covering part which is continuous with the lower covering part and can be worn on the foot; and a sole treatment part including a table disposed on the foot covering part and a protrusion protruding from the table for massaging the sole. The foot covering section and the sole treatment section include an attachment/detachment structure that enables the sole treatment section to be attached to and detached from the foot covering section. The detachable structure is configured to be attachable in any one of a plurality of attachment states in which the arrangement of the protrusions is different.

In each of the plurality of mounting states, the protuberance massages a different portion of the sole of the foot. Therefore, the air massage device capable of selecting the installation state of the sole treatment portion can provide various massage feelings to the sole.

Figure 3 shows the inner surface of the wearer 20 after deployment. Further, the wearing article 20 shown later in fig. 3 is the wearing article 20 worn on the right leg.

The upper covering portion 30 includes a first upper covering portion 31, a second upper covering portion 32, and a connecting portion 33. The first upper cover 31 is a portion to be worn on the thigh in the second wearing manner. The first upper covering portion 31 has a shape that can specify the longitudinal direction and the short direction. The first upper covering portion 31 includes a surface fastener. The surface fastener comprises a loop surface 31A and a hook surface 31B. The loop surface 31A is provided on the inner surface of the first upper covering portion 31, for example. The hook surface 31B is provided on the outer surface of the first upper covering portion 31, for example. The first upper cover 31 is worn on the leg by rolling the first upper cover 31 around the leg and adhering the loop surface 31A and the hook surface 31B together.

The second upper cover 32 is a part to be worn on the lower leg in the second wearing manner. The second upper covering portion 32 has a shape that can specify the longitudinal direction and the short direction. The second upper covering portion 32 includes a surface fastener. The face fastener includes a loop surface 32A and a hook surface 32B. The loop surface 32A is provided on the inner surface of the second upper covering portion 32, for example. The hook surface 32B is provided on the outer surface of the second upper covering portion 32, for example. The second upper cover 32 is worn on the leg by rolling the second upper cover 32 around the leg and adhering the loop surface 32A and the hook surface 32B together.

The connecting portion 33 is a portion connecting the first upper covering portion 31 and the second upper covering portion 32. When the upper covering portion 30 is worn on the knee in the second wearing manner, the connecting portion 33 opens forward so as to expose the knee. Therefore, when the upper cover 30 is worn on the leg in the second wearing manner, the user can easily perform the knee bending operation and the knee stretching operation, and the posture can be easily changed when the air massage apparatus 1 is used.

The wearing article 20 is further provided with a positioning part 90. The function of the positioning part 90 is to determine the position of the upper covering part 30 with respect to the leg by contacting with the popliteal fossa. The positioning portion 90 is provided, for example, at the center of the connecting portion 33 on the inner surface side of the upper covering portion 30. The popliteal fossa contacted by the locating portion 90 is one of the characteristically shaped portions of the leg. Since the upper cover 30 is worn by the positioning unit 90 targeting such a popliteal fossa, the user can easily wear the wearing article 20 on the leg.

The wearing article 20 further includes a sole treatment portion 100. The sole treatment section 100 functions to massage the sole. The sole treatment unit 100 is disposed in a portion of the inner surface of the foot cover 60 that contacts the sole.

Fig. 4 shows the internal structure of the inner surface side of the developed wearing article 20. The first upper air bag 41 is provided, for example, in a portion of the first upper covering portion 31 worn on the leg in the second wearing manner, which covers the front surface of the thigh. The first upper bag 41 includes a central portion 41A, a pair of side portions 41B, and a passage 41C. The central portion 41A, the pair of side portions 41B, and the passage 41C are continuous. The central portion 41A is provided to be sandwiched between the pair of side portions 41B. One end of the passage 41C is provided with a first supply port 41D. The other end of the passage 41C is connected to one side portion 41B. The air flowing from the first supply port 41D is supplied to the one side portion 41B via the passage 41C. The passage 41C is a substantially non-expanding portion.

The width of the side portions 41B in the longitudinal direction of the first upper covering portion 31 is wider than the width of the central portion 41A in the longitudinal direction of the first upper covering portion 31. Therefore, the pair of side portions 41B is more expanded than the central portion 41A. In one example, the central portion 41A is substantially unexpanded. Therefore, the front of the thigh is pinched by the inflation of the first upper bag 41, giving a feeling like rubbing to the front of the thigh. Therefore, the user can give a desired massage feeling to the front surface of the thigh.

The second upper air bag 42 is provided in a portion of the second upper covering portion 32 worn on the leg in the second wearing manner so as to cover the back surface of the lower leg. The second upper bag 42 includes a central portion 42A and a pair of side portions 42B. The central portion 42A and the pair of side portions 42B are continuous. The central portion 42A is provided so as to be sandwiched between the pair of side portions 42B. One side portion 42B is provided with a second supply port 42C.

The width of the side portions 42B in the short-side direction of the second upper covering portion 32 is wider than the width of the central portion 42A in the short-side direction of the second upper covering portion 32. Therefore, the pair of side portions 42B is more expanded than the central portion 42A. In one example, the central portion 42A is substantially unexpanded. Therefore, when the second upper bag 42 is inflated in the second wearing mode, the back surface of the lower leg is pinched, and the back surface of the lower leg is given a feeling of kneading. Therefore, in the second wearing system, a desired massage feeling is given to the back surface of the lower leg. On the other hand, when the second upper bag 42 is inflated in the first wearing manner, a sensation of kneading can be given to the back of the thighs. Therefore, in the first wearing system, a desired massage feeling is given to the back surface of the thigh.

The third upper bladder 43 is provided in a portion covering the popliteal fossa in the connecting portion 33 worn on the leg in the second wearing manner. In one example, the third upper airbag 43 is provided so as to straddle the portion of the first upper covering portion 31 that covers the back of the thighs and the portion of the connecting portion 33 that covers the popliteal fossa in the second wearing manner. The third upper bag 43 is provided with a third supply port 43A at the end on the side of the connecting portion 33. The

supply ports

41D, 42C, and 43A are connected to the first connection member 71 in proximity to each other.

The positioning portion 90 includes a projection 91. In one example, the positioning portion 90 constitutes a projection 91. The convex portion 91 is attached to the third upper air bag 43 so as to massage the popliteal fossa when the upper covering portion 30 is worn on the leg in the second wearing manner. Specifically, the convex portion 91 is attached to a portion of the third upper bag 43 that is disposed in the center of the connecting portion 33. In the example shown in fig. 3, the convex portion 91 protrudes toward the inner surface side of the upper covering portion 30.

An example of the wearing process of the wearing article 20 will be described with reference to fig. 5, 6A, and 6B.

Fig. 5 is a perspective view showing an example of a first wearing mode of the air massage device of fig. 1. The wearing article 20 is worn on the legs as follows, for example. First, the foot cover 60 is worn on the foot, and the lower cover 50 is worn on the lower leg. Next, the joint 80 is pulled so that the joint 80 faces the popliteal fossa. Next, the upper cover 30 is worn on the thigh so as not to cover the knee. At this time, an opening 81 is formed in front of the connection portion 80, and the knee is exposed from the opening 81. Thus, the wearing article 20 is worn on the leg in the first wearing manner.

Fig. 6A is a perspective view showing an example of a wearing state of the wearing article 20 before the upper cover 30 of the air massage apparatus of fig. 1 is worn. Fig. 6B is a perspective view showing an example of a second wearing mode of the air massage device of fig. 1.

The wearing article 20 is worn on the legs as follows, for example. First, as shown in fig. 6A, the foot cover 60 is worn on the foot, and the lower cover 50 is worn on the lower leg. Next, the connection portion 80 is folded such that the connection portion 80 is sandwiched between the upper cover portion 30 and at least one of the lower cover portion 50 and the leg when the upper cover portion 30 is worn on the leg. In one example, the coupling portion 80 is folded in accordance with the wearing position of the upper cover 30 with respect to the leg. Next, the connection portion 33 of the upper covering portion 30 is disposed in the popliteal fossa so that the positioning portion 90 is in contact with the popliteal fossa.

Next, as shown in fig. 6B, the upper covering section 30 is worn on the thigh and the lower leg across the knee with the positioning section 90 in contact with the popliteal fossa. Specifically, the first upper cover portion 31 is worn on the thigh, and the second upper cover portion 32 is worn on the calf. In one example, the second upper covering portion 32 is worn on the lower leg so as to overlap a part of the lower covering portion 50. At this time, an opening 34 is formed in front of the connecting portion 33, and the knee is exposed from the opening 34. Thus, the wearing article 20 is worn on the leg in the second wearing manner.

In the first wearing manner and the second wearing manner, the length of the wearing article 20 in the length direction of the leg is different. In one example, the length of the wearing article 20 in the first wearing manner is longer than the length of the wearing article 20 in the second wearing manner. Therefore, the wearer 20 can be worn on the leg by the first wearing system by a user having a short leg, which is a user having a length that can fit the leg such as the entire lower leg with the lower covering portion 50. Further, the user having such a length that a part of the lower leg is exposed when wearing the lower covering section 50, that is, the user having a long leg can wear the wearing article 20 on the leg by the second wearing system.

Fig. 7 is a front view showing the relationship between the first upper air bag 41 and the leg muscles when the upper cover 30 is worn on the leg in the second wearing manner.

The first upper bag 41 is disposed on the front surface of the thigh in the second attachment mode, and faces the quadriceps femoris MQ. Specifically, the first upper bag 41 is disposed around the knee on the front of the thigh, facing the root of the quadriceps femoris MQ. The root of quadriceps femoris MQ is a muscle with high massage effect. Therefore, by repeated expansion and contraction of the first upper air bag 41, the root of the quadriceps femoris MQ is massaged, and the legs are massaged efficiently.

Fig. 8 is a rear view showing the relationship between the various

upper air bags

42, 43 and the leg muscles when the upper cover 30 is worn on the leg in the second wearing manner.

In the second wearing mode, the second upper air bag 42 is disposed on the back surface of the lower leg, facing the gastrocnemius MG. Specifically, the second upper bag 42 is disposed around the knee on the back of the lower leg, facing the base of the gastrocnemius MG. The roots of gastrocnemius MG are muscles having a high massaging effect. Therefore, by repeated expansion and contraction of the second upper air bag 42, the root of the gastrocnemius MG is massaged, and the leg is massaged efficiently. When the upper cover portion 30 is worn on the leg in the first wearing manner, the second upper air bag 42 is disposed around the knee on the back surface of the thigh, and can massage the base of the posterior femoral muscle MH.

In the second wearing style, third upper bladder 43 is configured to straddle the back of the thigh and the popliteal fossa, facing primarily the posterior femoral muscle MH. Specifically, the third upper bag 43 is disposed around the knee on the back of the thigh, facing the base of the posterior femoral muscle MH. The root of the posterior femoral muscle MH is a muscle with a high massage effect. Therefore, the root of the posterior femoral muscle MH is massaged and the leg is massaged efficiently by the repeated expansion and contraction of the third upper air bag 43. With the inflation of the third upper balloon 43, the convex portion 91 of the positioning portion 90 comes into contact with the popliteal fossa. Therefore, an ideal massage feeling is given to the popliteal fossa. In one example, the popliteal muscles in the popliteal fossa, the popliteal lymph nodes, etc., are massaged by the protrusion 91. By wearing the upper covering portion 30 on the leg in the second wearing manner, the periphery of the knee is massaged by the upper airbags 41 to 43, and the popliteal fossa is massaged by the convex portion 91.

Fig. 9 is a rear view of the air massage device 1 of fig. 1. Fig. 10 is a perspective view of the sole treatment unit 300 of fig. 3.

Fig. 9 shows the outer surface of the wearer 20 after unfolding. For example, the first tube 111 is drawn out from a portion of the upper cover portion 30 corresponding to a position inside the center in the width direction of the leg in a state where the upper cover portion 30 is worn on the leg. The first hose 111 is arranged outside the upper cover 30 so as not to cross the center in the width direction of the leg. For example, the second hose 112 is drawn out from a portion of the lower cover portion 50 corresponding to a position inside the center in the width direction of the leg in a state where the lower cover portion 50 is worn on the leg. The second hose 112 is arranged not to cross the center in the width direction of the leg at the outer portion of the lower cover portion 50. Therefore, when the user wearing the wearing article 20 sits on the chair, the

hoses

111 and 112 are not easily sandwiched between the legs and the chair. In addition, the

hoses

111, 112 are not easily pinched between the legs and the ground when the user wearing the wearing article 20 sits on the ground. Therefore, the user does not easily feel a sense of incongruity.

Fig. 10 shows the appearance of the sole treatment portion 100. The sole treatment portion 100 includes a stage 101 and a protrusion 102. The stage 101 is disposed on the foot cover 60 (see fig. 3). The projection 102 projects upward from the table 101 so as to massage the sole of a foot. One example of the number of the projections 102 is two. The two protrusions 102 are disposed at point-symmetrical positions on the stage 101. The heights of the two protrusions 102 are different from each other.

As shown in fig. 3 and 10, the foot covering portion 60 and the sole treatment portion 100 include an attachable and detachable structure that enables the sole treatment portion 100 to be attached to the foot covering portion 60 and the sole treatment portion 100 to be detached from the foot covering portion 60. The detachable structure is configured to be capable of selecting at least two mounting states in which the arrangement of the protrusion 102 differs around the central axis along the vertical direction of the sole treatment portion 100. In one example, the detachable structure can select four attachment states.

The detachable structure includes an insertion portion 101A and an inserted portion 60A. The insertion portion 101A is provided on the stage 101 so as to protrude in the planar direction of the stage 101. An example of the number of the insertion portions 101A is four. Each insertion portion 101A is provided so as to protrude in the vertical direction and the horizontal direction of the base 101 when the sole treatment portion 100 is viewed in plan, for example. The inserted portion 60A is provided in a portion of the inner surface of the foot covering portion 60 that contacts the ball of the foot. The inserted portion 60A has a structure in which the insertion portion 101A can be inserted. One example of the number of the inserted portions 60A is two. The two inserted portions 60A are disposed to face each other.

For example, the sole treatment unit 100 is attached to the foot covering unit 60 by inserting two insertion units 101A protruding in opposite directions into the corresponding inserted units 60A. The arrangement of each projection 102 with respect to the table 101 is changed by changing the relationship between the insertion portion 101A and the inserted portion 60A, that is, changing the attachment state of the attachment/detachment structure. Thus, the protrusions 102 massage different portions of the sole of the foot in the four mounting states, respectively. Therefore, the air massage device 1 capable of selecting the attachment state of the sole treatment portion 100 can provide various massage feelings to the sole.

An example of a method of using the air massage apparatus 1 will be described with reference to fig. 1.

The user using the air massage device 1 can select a wearing style according to the length of his or her leg, for example, and wear the wearing article 20 on both legs according to the selected wearing style. For example, the user with short legs may select the first wearing system, and the user with long legs may select the second wearing system. Then, the user operates the operation unit 12 to turn on the power supply and selects a massage course or the like. Thereby, the massage by the air massage apparatus 1 is started.

According to the air massage device 1, the length of the wearing object 20 in the length direction of the leg is different depending on the wearing manner. Therefore, the user can select a wearing manner corresponding to the length of his/her leg to wear the wearing article 20 on the leg. The upper air bag 40 and the lower air bag 51 are disposed at positions suitable for leg massage, and the

air bags

40 and 51 give a desired massage feeling to the legs. In this way, the air massage device 1 can appropriately massage the legs in accordance with various body shapes of the user.
