Furthermore, the embodiments described below are examples of the stretching exercise machine of the present invention and are not limited to the structure of the illustrated stretching exercise machine of the present invention.

[0072] (Overview of the stretching exercise machine)

[0073] Figure 1 This is a front view showing the stretching exercise machine (first embodiment) of the present invention. Figure 2 This is a rear view showing the stretching exercise machine (first embodiment) of the present invention. Figure 3 This is a left view showing the stretching exercise machine (first embodiment) of the present invention. Figure 4 This is a perspective view showing the stretching exercise machine of the present invention being worn by a user. Figure 5 This is an illustrative diagram showing the treated area of ​​a user utilizing a stretching exercise machine. Figures 1-4 The figure shows one embodiment of the stretching exercise machine of the present invention, namely stretching exercise machine 10. Figures 1-4 The stretching exercise machine 10 shown is a first embodiment of the stretching exercise machine 10 of the present invention. In the following description, the stretching exercise machine 10 of the first embodiment will also be referred to as the first stretching exercise machine 10A. Furthermore, in the following description, when simply referred to as "stretching exercise machine 10", the common structure of the first stretching exercise machine 10A and the stretching exercise machine 10 of other embodiments (the second stretching exercise machine 10B and the third stretching exercise machine 10C described later) will be described.

[0074] like Figure 4 As shown, the stretching exercise machine 10 is a backpack-type device worn on the shoulders and back of the user U. The stretching exercise machine 10 is used to stretch the back B of the user U (see reference). Figure 5The purpose of the stretching exercise machine 10 is to press the treated area X (see reference) in the back B of the user U. Figure 5 This allows for stretching of the back (B). Furthermore, the stretching exercise machine 10 can correct the posture of the user (U) by stretching the back (B) of the user (U).

[0075] like Figure 5 As shown, the treatment area X is the region between the left and right scapulae K in the back B of the user U. Alternatively, the treatment area X can also include the region where the user U's scapulae K are located. Furthermore, in the following description, the left shoulder S is also referred to as left shoulder S1, the right shoulder S as right shoulder S2, the left scapula K as left scapula K1, and the right scapula K as right scapula K2.

[0076] In the following description, based on the state where the stretching exercise machine 10 is properly worn on the user U in a basic posture, the forward-backward direction and the direction parallel to it are defined as the forward-backward direction of the stretching exercise machine 10, the left-right direction and the direction parallel to it are defined as the left-right direction of the stretching exercise machine 10, and the up-down direction and the direction parallel to it are defined as the up-down direction of the stretching exercise machine 10. Furthermore, the "basic posture" of the user U referred to in this description includes postures where the user U's spine extends vertically and the head is located at the top of the spine, postures where the user U is standing upright on a horizontal surface, and postures where the user U is sitting on a chair with a horizontal seat, etc.

[0077] (Overall structure of the stretching exercise machine)

[0078] like Figures 1-4 As shown, the stretching exercise machine 10 has a main body 11, a shoulder hanging part 12, and a fastening part 13.

[0079] (Main Body)

[0080] Figure 6 This is the front view of a stretching exercise machine showing the shoulder area extended upwards. Figure 7 This is a partial sectional view of the main body. For example... Figure 4 As shown, the main body 11 is worn on the back B of the user U (see reference). Figure 5 (The part of the text is missing.) Figures 1-4 , Figure 6 and Figure 7 As shown, the main body 11 consists of an outer cover 15 and a core material 16 (see reference). Figure 7 )constitute.

[0081] like Figure 6 and Figure 7As shown, the outer cover 15 is composed of a first fabric member 15a disposed on the front side and a second fabric member 15b disposed on the rear side. The outer cover 15 is configured as a bag-shaped structure with an internal space created by sewing the outer periphery portions of the first fabric member 15a and the second fabric member 15b together. The core material 16 is housed within the internal space of the outer cover 15. In this embodiment, the outer cover 15 (the first fabric member 15a and the second fabric member 15b) is made of a soft fabric such as artificial leather or mesh fabric. Furthermore, the main body 11 may also be configured to appropriately include other cushioning materials.

[0082] The main body 11 is worn on the back B of the user U (see reference). Figure 5 In the case of [the situation described above], the first fabric member 15a contacts the back B. The first fabric member 15a has a first surface 15c that contacts the back B of the user U and a second surface 15d formed on the side opposite to the first surface 15c. The second surface 15d faces the second fabric member 15b.

[0083] The core material 16 is a plate-shaped member made of an elastic material. In this embodiment, the core material 16 is made of resin. The core material 16 is housed in the space inside the outer cover 15. The front surface of the core material 16 faces the second surface 15d, and the rear surface faces the second fabric member 15b.

[0084] As described above, the main body 11 has a three-layer structure, consisting of a first fabric member 15a, a core material 16, and a second fabric member 15b, starting from the front. The main body 11 accommodates the pressing mechanism 30, which will be described later, between the first fabric member 15a and the core material 16.

[0085] (Pressing mechanism)

[0086] like Figure 6 and Figure 7 As shown, the main body 11 also includes a pressing mechanism 30. The pressing mechanism 30 is used to press the treated area X of the user U (see reference). Figure 5 The pressing mechanism 30 is configured to include an air bladder 40. The air bladder 40 inflates by enclosing air inside and contracts by deflating the air inside. In this embodiment, the air bladder 40 is a rubber bag-shaped member. By inflating the air bladder 40, the pressing mechanism 30 can generate a pressing force to press the treated area X. Furthermore, in the following description, the air bladder 40 constituting the first stretching motion machine 10A is also referred to as the first air bladder 41.

[0087] like Figure 7As shown, in the stretching exercise machine 10, the airbag 40 is disposed in the space between the first fabric member 15a and the core material 16 inside the outer cover 15. In this structure, the airbag 40 is restricted from bulging rearward by the core material 16. In other words, the airbag 40 bulges in a direction other than rearward (particularly forward). Therefore, by placing the core material 16 behind the airbag 40, the stretching exercise machine 10 can suppress the loss of pressure transmission caused by the expansion of the airbag 40. Therefore, in the stretching exercise machine 10, the pressing mechanism 30 can reliably press the treated area X using the expansion of the airbag 40.

[0088] Furthermore, the stretching exercise machine 10 of the present invention can release the pressure on the treated area X by extracting the air sealed inside and causing the airbag 40 to contract. By inflating the airbag 40 or alternatingly and repeatedly inflating and contracting the airbag 40, the stretching exercise machine 10 can apply a stretching effect to the back B (around the treated area X) of the user U.

[0089] (Shoulder area)

[0090] like Figure 4 As shown, the shoulder strap 12 is worn on the shoulder S of the user U (see reference). Figure 5 (The part of the text is missing.) Figures 1-4 as well as Figure 6 As shown, the shoulder strap 12 is a strap-shaped portion integrally formed with the main body 11, extending from the left and right ends of the upper part of the main body 11. The shoulder strap 12 is worn on the left shoulder S1 of the user U (see reference). Figure 5 The left shoulder strap 12a and the right shoulder strap S2 worn by the user U (see reference) Figure 5 ) on the right shoulder 12b.

[0091] The left shoulder rest 12a extends from the upper left end of the main body 11, and the right shoulder rest 12b extends from the upper right end of the main body 11. Therefore, the stretching exercise machine 10 is configured in a roughly U-shape by the main body 11 and the left and right shoulder rests 12a and 12b. The left and right shoulder rests 12a and 12b are arranged with a gap in the left-right direction that is wider than the user's neck (U).

[0092] The shoulder hanging portion 12 is composed of an outer cover 17 and a cushioning material (not shown). The outer cover 17 is composed of a first fabric member 17a and a second fabric member 17b. The first fabric member 17a and the second fabric member 17b are made of soft fabrics such as artificial leather or mesh fabric. The outer cover 17 is constructed as a bag shape with an internal space by sewing the outer periphery portions of the first fabric member 17a and the second fabric member 17b together with the cushioning material. The shoulder hanging portion 12 with such a structure has flexibility and shape retention. The first fabric member 17a is connected in series with the first fabric member 15a of the outer cover 15, and the second fabric member 17b is connected in series with the second fabric member 15b of the outer cover 15. The space inside the outer cover 17 is used as a receiving portion 18 to accommodate the drive mechanism 50, which will be described later. The shoulder hanging portion 12 also has a holding portion 19 for holding the buckle 22, which will be described later.

[0093] Furthermore, although descriptions and illustrations are omitted in this embodiment, the stretching exercise machine 10 of the present invention may also include a strap member connecting the left and right shoulder rests 12a, 12b at a position in front of the user U's chest. When using the strap member, the left and right shoulder rests 12a, 12b can be securely pressed against the user U's body. In this case, the pressing force generated by the pressing mechanism 30 can be applied to the treated area X more reliably.

[0094] The stretching exercise machine 10 is worn by the user U by hanging the left and right shoulder hanging parts 12a and 12b on the user U's shoulders S1 and S2 respectively. Moreover, by hanging the shoulder hanging parts 12 on the user U's shoulders S, the main body 11 of the stretching exercise machine 10 can be arranged on the user U's back B, thereby allowing the pressing mechanism 30 (airbag 40) to be positioned to press the treated area X.

[0095] (Fastening part)

[0096] like Figure 4 As shown, the fastening part 13 is the part that fastens the shoulder hanging part 12 and the main body part 11 to the user U. The stretching exercise machine 10 fixes the main body part 11 to the back B of the user U and the shoulder hanging part 12 to the shoulder S of the user U by fastening the fastening part 13. The fastening part 13 includes: a left fastening part 13a connecting the left shoulder hanging part 12a and the main body part 11; and a right fastening part 13b connecting the right shoulder hanging part 12b and the main body part 11.

[0097] like Figures 1-4 As shown, each fastening part 13a and 13b has a fastening band 21, a buckle 22 and a handle part 23.

[0098] The fastening band 21 is a flexible strip made of synthetic fibers or the like (e.g., nylon). In the left fastening section 13a, the fastening band 21 extends from the lower left end of the main body 11 toward the left shoulder section 12a. In the right fastening section 13b, the fastening band 21 extends from the lower right end of the main body 11 toward the right shoulder section 12b. A handle 23 is provided at the end of the fastening band 21 opposite to the side that is fixed to the main body 11.

[0099] The user U wearing the stretching machine 10 in a basic posture (see reference). Figure 4 Below, the fastening strap 21 extends forward from both the left and right ends below the main body 11. The fastening strap 21, extending forward, passes through the slit 12c formed in the shoulder hanging portion 12 and is inserted through the buckle 22 located on the front side of the shoulder hanging portion 12. Furthermore, the fastening strap 21 changes its extension direction from forward to backward within the buckle 22, passes through the slit 12c again, and extends downward at the rear of the shoulder hanging portion 12.

[0100] When the handle 23 at the top of the fastening strap 21 is pulled downwards, the fastening strap 21 pulls the lower end of the main body 11 closer to the shoulder strap 12. As a result, the main body 11 fits snugly against the back B of the user U. Thus, the main body 11 is fixed to the back of the user U. Furthermore, although the description and illustrations are omitted in this embodiment, the portion of the fastening strap 21 that contacts the user U may also be provided with cushioning material. By sandwiching the cushioning material between the user U and the fastening strap 21, the snugness of the fastening strap 21 and the comfort of wearing the stretching exercise machine 10 can be improved.

[0101] The buckle 22 is connected to and held in place by the annular retaining portion 19 located in the middle of the shoulder strap 12. When the buckle 22 is positioned with its tip (top portion 27 described later) facing downwards, it prevents the fastening strap 21 from moving in the extending direction. When positioned with its tip facing forward and raised, the buckle 22 allows the fastening strap 21 to move in the extending direction. The function of the buckle 22 will be explained in detail later.

[0102] (Drive mechanism)

[0103] like Figure 1 , Figure 3 as well as Figure 6As shown, the stretching exercise machine 10 also has a drive mechanism 50. The drive mechanism 50 is a mechanism for driving the pressing mechanism 30. The drive mechanism 50 has a pump 51, a battery 52, and an air tube (piping component) 53. In the stretching exercise machine 10 of the present invention, the pump 51 is housed in a housing 18 of the left shoulder portion 12a, and the battery 52 is housed in a housing 18 of the right shoulder portion 12b. The air tube 53 is housed inside the left shoulder portion 12a and the main body portion 11, connecting the air bag 40 and the pump 51. The pump 51 supplies air into or exhausts air from the air bag 40 via the air tube 53. The stretching exercise machine 10 has a wiring 54 that electrically connects the pump 51 and the battery 52. ​​The wiring 54 is routed inside the right shoulder portion 12b, the main body portion 11, and the left shoulder portion 12a.

[0104] like Figure 1 As shown, the stretching exercise machine 10 has an operation unit 31 on the left shoulder rest 12a. The operation unit 31 is a switch that can turn the pump 51 on or off. By operating the operation unit 31, the user U can select whether the drive mechanism 50 (pump 51) is on or off. Specifically, when the user U operates the operation unit 31, the pump 51 operates using electricity supplied from the battery 52, supplying air from the pump 51 to the airbag 40. As a result, the airbag 40 inflates. Alternatively, when the user U operates the operation unit 31, the pump 51 stops and the air inside the airbag 40 is expelled to the outside. As a result, the airbag 40 contracts.

[0105] Furthermore, in the stretching exercise machine 10 of this embodiment, the pump 51 is housed in the receiving portion 18 of the left shoulder portion 12a, and the battery 52 is housed in the receiving portion 18 of the right shoulder portion 12b. However, in the stretching exercise machine 10 of the present invention, the arrangement of the pump 51 and the battery 52 is not limited to this, and they can also be arranged in a left-right reversal configuration. Additionally, the stretching exercise machine 10 of the present invention may, for example, have a configuration in which both the pump 51 and the battery 52 are housed in the receiving portion 18 of either the left or right side. Furthermore, the stretching exercise machine 10 of the present invention may also have a configuration in which the pump 51 and the battery 52 are housed in the main body portion 11. Moreover, a portion of the drive mechanism 50 of the stretching exercise machine 10 of the present invention may be disposed outside the shoulder portion 12.

[0106] The stretching exercise machine 10 drives the pressing mechanism 30 (airbag 40) via the drive mechanism 50, thereby enabling it to press the treated area X of the user U (see reference). Figure 5 The stretching exercise machine 10, by pressing the treated area X with the pressing mechanism 30 (airbag 40), achieves the same effect as pulling the left and right shoulders S1 and S2 of the user U towards the back B and inwards. Therefore, according to the stretching exercise machine 10, the muscles of the back B surrounding the treated area X can be stretched. As a result, a stretching effect similar to chest expansion can be achieved, and the posture of the user U can be corrected.

[0107] (Protrusion)

[0108] Figure 8 This is a partial front view showing the configuration of the protrusion relative to the main body. For example... Figure 8 As shown, the stretching exercise machine 10 of the present invention may also have a structure in which a protrusion 60 is present in the main body 11.

[0109] The protrusion 60 is a convex portion provided on the first surface 15c of the main body 11. The components constituting the protrusion 60 may be, for example, natural stone or hard resin. The shape of the components constituting the protrusion 60 may also be, for example, a cone shape, a frustum of a cone shape, a square pyramid shape, or a triangular pyramid shape. In this embodiment, the protrusion 60 is composed of a Go-shaped component.

[0110] The protrusion 60 is provided in the area of ​​the first surface 15c that overlaps with the configuration area of ​​the airbag 40. The protrusion 60 can also be detachably provided on the first surface 15c, for example, using a hook and loop fastener. With this structure, the stretching exercise machine 10 can press the treated area X via the protrusion 60 when the airbag 40 inflates. In this case, the pressing force generated by the pressing mechanism 30 can be concentrated at the contact point between the back B and the protrusion 60, thereby pressing the treated area X. This increases the pressing force applied to the treated area X. Furthermore, in this embodiment, two protrusions 60 are provided, but only one protrusion 60 may be provided, or more than three protrusions 60 may be provided. Additionally, in the stretching exercise machine 10 of the present invention, the protrusion 60 may be omitted.

[0111] (Pocket section)

[0112] Figure 9 This is a partial front view showing the configuration of the pocket and protrusion relative to the main body. For example... Figure 9 As shown, in the stretching machine 10 with the protrusion 60, the main body 11 may also have a pocket portion 70. The pocket portion 70 is a bag (pocket) shaped part that can accommodate the protrusion 60, and is made of the same fabric member as the outer cover 15. The pocket portion 70 is provided in the area of ​​the first surface 15c that overlaps with the arrangement area of ​​the airbag 40.

[0113] In the case of having a pocket portion 70, the protrusion 60 is accommodated within the pocket portion 70. Therefore, the protrusion 60 can be positioned on the first surface 15c. With this structure, the arrangement of the protrusion 60 in the stretching machine 10 can be freely changed as long as it is inside the pocket portion 70. In this case, it is easier to change the arrangement of the protrusion 60. Furthermore, the stretching machine 10 can accommodate a plurality of protrusions 60 inside the pocket portion 70. Additionally, the pocket portion 70 can be omitted in the stretching machine 10 of the present invention.

[0114] (Regarding the tightness and looseness of the main body using the fastening mechanism)

[0115] Figure 10 It is a partial sectional view showing the fastening state of the main body and the shoulder part using the fastening part. Figure 11 This is a partial sectional view showing the relaxed state of the main body and shoulder section using fasteners. For example... Figure 10 as well as Figure 11 As shown, the buckle 22 has a support end 24, a middle frame portion 25, a lower frame portion 26, and a top end portion 27. The buckle 22 also has a first belt insertion hole 28 formed between the middle frame portion 25 and the lower frame portion 26, and a second belt insertion hole 29 formed between the lower frame portion 26 and the top end portion 27.

[0116] The support end 24 is a generally prismatic frame, horizontally positioned at the upper end of the buckle 22. The support end 24 forms the upper side of the buckle 22. The support end 24 is inserted through an annular retaining part 19 provided on the shoulder part 12 and is held by the retaining part 19 to be rotatable. Therefore, the buckle 22 is rotatably connected to the shoulder part 12 with the support end 24 as the fulcrum.

[0117] The middle frame 25 is a generally flat frame that is horizontally positioned in the middle of the buckle 22 in the vertical direction. The middle frame 25 has a downward slope in front of the buckle 22, forming the upper outer periphery of the first buckle insertion hole 28.

[0118] The lower frame 26 is a generally prismatic frame that is horizontally positioned below the middle frame 25. The lower frame 26 extends between the left and right side edges of the buckle 22, forming the outer periphery below the first through hole 28 and the outer periphery above the second through hole 29.

[0119] The first strap insertion hole 28 is a hole formed between the middle frame portion 25 and the lower frame portion 26. The fastening strap 21, extending forward from the main body portion 11, is inserted through the first strap insertion hole 28 from the rear to the front. The second strap insertion hole 29 is a hole formed between the lower frame portion 26 and the top portion 27. The fastening strap 21, which reaches the front of the buckle 22 through the first strap insertion hole 28 and makes a U-shaped turn along the lower frame portion 26, is inserted through the second strap insertion hole 29 from the front to the rear. Both the first strap insertion hole 28 and the second strap insertion hole 29 are through holes with approximately the same width as the fastening strap 21.

[0120] The fastening strap 21 passes from the rear through the slit 12c of the shoulder portion 12, and then through the first strap insertion hole 28 to reach the front of the buckle 22. The fastening strap 21 then bends into a U-shape along the lower frame portion 26. At this time, the fastening strap 21 changes its extension direction along the lower frame portion 26 from forward to downward, and then from downward to rearward. The fastening strap 21 then returns to the rear side of the shoulder portion 12 through the second strap insertion hole 29 and the slit 12c of the shoulder portion 12, and then its extension direction is downward at the rear side of the shoulder portion 12.

[0121] At the portion where the fastening band 21 passes through the slit 12c of the shoulder portion 12, the upper and lower fastening bands 21 converge, causing their surfaces to contact each other, thereby restricting displacement in the extending direction. Furthermore, the fastening band 21 restricts displacement in the extending direction by wrapping it around the lower frame portion 26 of the buckle 22 in a U-shaped rotation, utilizing the frictional force between the buckle 22 and the lower frame portion 26. The stretching motion machine 10 of the present invention can use a buckle 22 with such a structure to restrict the displacement of the fastening band 21 in the extending direction.

[0122] When the handle 23 at the top of the fastening strap 21 is pulled downwards, the length L between the endpoint P of the main body 11 and the contact point Q of the lower frame 26 is shortened. As a result, the distance between the main body 11 and the shoulder hanging part 12 is shortened, thereby the main body 11 and the shoulder hanging part 12 are worn by the user U. At this time, the main body 11 is in a state of close contact with the back B. In this description, this state in which the main body 11 is fastened to the back B by the fastening part 13 is referred to as the fastened state. In this description, the length L between points P and Q of the fastening strap 21 in the fastened state is defined as the first length L1.

[0123] In the secured state (where the main body 11 is secured to the back B using the fastening part 13), when the lower end of the shoulder strap 12 is lifted forward and upward, the buckle 22 rotates forward and upward with the support end 24 as the fulcrum. At this time, the portion of the fastening strap 21 that extends further backward and downward than the lower frame 26 is lifted as the lower frame 26 rotates. As a result, a gap is created between the fastening strap 21 wound around the lower frame 26 and the lower frame 26, thereby releasing the restriction on displacement imposed by the lower frame 26, allowing the fastening strap 21 to move in the extending direction.

[0124] As a result, the length L between the endpoint P of the main body 11 of the fastening strap 21 and the contact point Q of the lower frame 26 is extended. At this time, the main body 11 is no longer tightly attached to the back B, and the main body 11 and the shoulder strap 12 can be detached from the user U. In this description, this state in which the main body 11 is loosened relative to the back B by the fastening part 13 is called the loosened state. In this description, the length L between points P and Q of the fastening strap 21 in the loosened state is defined as the second length L2. The second length L2 is greater than the first length L1 (L2 > L1).

[0125] The stretching exercise machine 10 of the present invention allows the user U to easily adjust the length L between points PQ of the fastening strap 21 to a first length L1 by simply operating the handle 23. Therefore, the user U can easily wear the stretching exercise machine 10 on their back B. Furthermore, the stretching exercise machine 10 of the present invention allows the user U to easily adjust the length L between points PQ of the fastening strap 21 to a second length L2 by simply operating the shoulder strap 12. Therefore, the user U can easily remove the stretching exercise machine 10 from their back B.

[0126] (Regarding the first stretching exercise machine 10A of the first embodiment)

[0127] Figures 1-4 as well as Figure 6 The first stretching exercise machine 10A shown has an airbag 40 (first airbag 41).

[0128] The first stretching exercise machine 10A with this structure can press the treated area X of the user U using the first airbag 41. By pressing the treated area X using the first airbag 41, the first stretching exercise machine 10A can achieve the same effect as stretching the left and right shoulders S1 and S2 of the user U towards the back B and inward, respectively. Therefore, according to the first stretching exercise machine 10A, the muscles of the back B around the treated area X can be stretched, and the effect of correcting the posture of the user U can be achieved.

[0129] (Regarding the stretching exercise machine of the second embodiment)

[0130] Figure 12 This is a partial front view showing the stretching exercise machine (second embodiment) of the present invention. Figure 13 This is an explanatory diagram of the first and second treatment areas of a user based on a second stretching exercise machine. Figure 14 This is an explanatory diagram illustrating an example of the configuration of the protrusions and pockets in a second stretching exercise machine. Figure 12The stretching exercise machine 10 shown is a second embodiment of the stretching exercise machine 10 of the present invention. In the following description, the stretching exercise machine 10 of the second embodiment will be referred to as the second stretching exercise machine 10B. The second stretching exercise machine 10B has a plurality of airbags 40, which is different from the first stretching exercise machine 10A described above (see reference 10A). Figure 1 The second stretching machine 10B differs from the first stretching machine 10A in several aspects, but otherwise shares the same structure. In this description, the differences in structure between the second stretching machine 10B and the first stretching machine 10A will be explained, while the differences in structure will be omitted.

[0131] like Figure 12 As shown, the second stretching exercise machine 10B has a plurality of airbags 40. Specifically, the second stretching exercise machine 10B has two airbags 40. One of the two airbags 40 of the second stretching exercise machine 10B is referred to as the first airbag 41. The first airbag 41 of the second stretching exercise machine 10B is the same as the first airbag 41 of the first stretching exercise machine 10A. The other of the two airbags 40 of the second stretching exercise machine 10B is referred to as the second airbag 42. Furthermore, although the case with two airbags 40 is illustrated in this embodiment, the second stretching exercise machine 10B may also have a structure with three or more airbags 40.

[0132] The second stretching machine 10B applies pressure to the two treatment areas X (refer to...). Figure 13 (as the recipient of treatment.) For example... Figure 13 As shown, the second stretching machine 10B uses the first treated area X1 and the second treated area X2 as the treated area X. The first treated area X1 is the treated area X (see reference). Figure 5 The area below the treatment area ( ). The second treated area X2 is the treated area X (refer to ) Figure 5 The area above the first treated area X1 is located higher than the first treated area. Furthermore, the second stretching machine 10B can treat three or more areas.

[0133] In the second stretching exercise machine 10B, the first airbag 41 is configured to press the first treated area X1, and the second airbag 42 is configured to press the second treated area X2. The second stretching exercise machine 10B presses the first treated area X1 and / or the second treated area X2 of the user U by actuating the pressing mechanism 30 via the drive mechanism 50. Furthermore, in the second stretching exercise machine 10B, the drive mechanism 50 preferably also has a switching valve capable of switching the air supply destination based on the pump 51. In this case, the switching valve and each airbag 41, 42 are connected via an air tube 53.

[0134] The second stretching exercise machine 10B, with this structure, can stretch the back muscles B surrounding the first treated area X1 and the back muscles B surrounding the second treated area X2. Therefore, the second stretching exercise machine 10B allows the user U to select a treatment area from either the first treated area X1 or the second treated area X2, or both, according to their physique and preferences, thereby achieving a more reliable stretching effect.

[0135] like Figure 14 As shown, the second stretching exercise machine 10B may also have a structure in which a plurality of pocket portions 70 for arranging protrusions 60 are provided on the first surface 15c of the main body portion 11. Specifically, the second stretching exercise machine 10B provides a first pocket portion 70 (first pocket portion 71) at a position corresponding to the arrangement area of ​​the first airbag 41, and provides a second pocket portion 70 (second pocket portion 72) at a position corresponding to the arrangement area of ​​the second airbag 42.

[0136] According to this structure, the second stretching exercise machine 10B can select from a plurality of pocket portions 70 (first pocket portion 71 and second pocket portion 72) to accommodate the protrusion 60. Therefore, the position of the back B pressed by the protrusion 60 can be easily changed according to the user U's preference. Furthermore, the second stretching exercise machine 10B can also have a structure in which the protrusion 60 is directly mounted (without using the pocket portion 70) on the first surface 15c of the main body 11 at a position corresponding to the placement area of ​​the first airbag 41 and the second airbag 42.

[0137] (Regarding the stretching exercise machine of the third embodiment)

[0138] Figure 15 This is a partial front view of the stretching exercise machine (third embodiment) of the present invention. Figure 16 This is an explanatory diagram of the third and fourth treatment areas for the user of the third stretching exercise machine. Figure 17 This is an explanatory diagram illustrating an example of the configuration of the protrusions and pockets in a third stretching exercise machine. Figure 15 The stretching exercise machine 10 shown is a third embodiment of the stretching exercise machine 10 of the present invention. In the following description, the stretching exercise machine 10 of the third embodiment will be referred to as the third stretching exercise machine 10C. The third stretching exercise machine 10C has a plurality of air bladders 40, which is different from the first stretching exercise machine 10A described above (see reference 10A). Figure 1 Unlike the first stretching exercise machine 10A, the third stretching exercise machine 10C has the same structure in other aspects. Furthermore, the arrangement of the plurality of airbags 40 in the third stretching exercise machine 10C is the same as that in the second stretching exercise machine 10B (see reference). Figure 12(Different from) In this description, regarding the third stretching machine 10C, the differences in structure between it and the first stretching machine 10A and the second stretching machine 10B will be explained, while the differences in structure with them will be omitted.

[0139] like Figure 15 As shown, the third stretching exercise machine 10C has a plurality of airbags 40. Specifically, the third stretching exercise machine 10C has two airbags 40. One of the two airbags 40 of the third stretching exercise machine 10C is referred to as the third airbag 43. The other of the two airbags 40 of the third stretching exercise machine 10C is referred to as the fourth airbag 44. Furthermore, in this embodiment, the case with two airbags 40 is illustrated, but the third stretching exercise machine 10C may also have a structure with three or more airbags 40.

[0140] The third stretching machine 10C will treat two areas X ( Figure 16 (Refer to) as the subject of treatment. For example... Figure 16 As shown, the third stretching machine 10C uses the third treated area X3 and the fourth treated area X4 as treated areas X. The third treated area X3 is treated area X (see reference). Figure 5 The area further to the left than the spine. The fourth treated area X4 is the treated area X (see reference). Figure 5 The area further to the right than the spine. Furthermore, the third stretching machine 10C can treat more than three areas.

[0141] In the third stretching exercise machine 10C, the third airbag 43 is configured to press the third treated area X3, and the fourth airbag 44 is configured to press the fourth treated area X4. The third stretching exercise machine 10C presses the third treated area X3 and / or the fourth treated area X4 of the user U by actuating the pressing mechanism 30 via the drive mechanism 50. Furthermore, in the third stretching exercise machine 10C, the drive mechanism 50 preferably also has a switching valve capable of switching the air supply destination based on the pump 51. In this case, the switching valve and each airbag 43, 44 are connected via an air tube 53.

[0142] The third stretching exercise machine 10C, with this structure, can stretch the back muscles B surrounding the third treated area X3, and can also stretch the back muscles B surrounding the fourth treated area X4. Therefore, the third stretching exercise machine 10C allows the user U to select the treatment area from either the third treated area X3 or the fourth treated area X4, or both, according to their physique or preference, thereby achieving a more reliable stretching effect.

[0143] like Figure 17As shown, the third stretching exercise machine 10C may also have a structure in which a plurality of pocket portions 70 for arranging protrusions 60 are provided on the first surface 15c of the main body portion 11. Specifically, the third stretching exercise machine 10C provides a plurality of pocket portions 70 (third pocket portion 73 and fourth pocket portion 74) at positions corresponding to the arrangement area of ​​the third airbag 43, and provides a plurality of pocket portions 70 (fifth pocket portion 75 and sixth pocket portion 76) at positions corresponding to the arrangement area of ​​the fourth airbag 44.

[0144] According to this structure, the third stretching exercise machine 10C allows selection of a pocket 70 (from the third pocket 73 to the sixth pocket 76) to accommodate the protrusion 60. This allows for easy adjustment of the position of the back B pressed by the protrusion 60 according to the user's preference. Alternatively, the third stretching exercise machine 10C can also have a structure where the protrusion 60 is directly mounted (without using the pocket 70) on the first surface 15c of the main body 11 at a position corresponding to the placement area of ​​the third airbag 43 and the fourth airbag 44.

[0145] (First variation of the stretching exercise machine)

[0146] In the stretching exercise machine 10 of this embodiment, the fastening part 13 may, for example, be composed of hook and loop fasteners (not shown) clamped between the shoulder hanger 12 and the fastening strap 21. In this case, the hook and loop fasteners preferably include a first hook and loop fastener on the shoulder hanger 12 side and a second hook and loop fastener on the fastening strap 21 side. With the fastening part composed of such hook and loop fasteners, the shoulder hanger 12 (shoulder hanger) is positioned above the user's shoulder S, and after the fastening strap 21 is brought to the front or back under the user's armpit, the two straps (shoulder hanger 12 and fastening strap 21) are secured using the first and second hook and loop fasteners. At this time, the length of the fastening strap 21 can be easily adjusted by adjusting the locking positions of the first and second hook and loop fasteners. In addition, in this case, the fastening part can be constructed more easily, and the shoulder hanger 12 and fastening strap 21 can be attached to and detached from the user's shoulder S more easily.

[0147] (Second variation of the stretching exercise machine)

[0148] The stretching exercise machine of the present invention may, for example, have a torso strap (not shown) extending laterally from the main body and wrapping around the user's torso. In this case, by wrapping and securing the torso strap around the user's torso, the main body can be secured to the user's back. Furthermore, in this case, it is not necessary to fasten the shoulder strap to the shoulder. At this time, the shoulder strap 12 and the fastening strap 21 are continuously and integrally formed, and can be a loop-shaped strap. According to the stretching exercise machine having such a torso strap, it is easier to attach and detach the main body relative to the user's back.

[0149] In other words, the stretching exercise machine 10 of the second modification described above has: a main body 11 with a pressing mechanism 30 for pressing the user U's body; and a torso strap (not shown) extending from the main body 11 and fastened to the user U's body (torso). The stretching exercise machine 10 of the second modification is used by wearing the main body 11 on the user U's back B. When the torso strap is fastened to the user U's body, the main body 11 is worn from the user U's left and right shoulders S1, S2 to the back B, and the pressing mechanism 30 is positioned at a location where it can press the treated area X, including the area between the left and right scapulae K1, K2 in the user U's back B. With this structure, the stretching exercise machine 10, like the stretching exercise machine 10 of the other embodiments described above, can stretch the muscles of the user U's back B, allowing the user U to experience a stretching effect.

[0150] (The function and effects of this implementation method)

[0151] The following describes the functions and effects of the stretching exercise machine 10 of this embodiment.

[0152] (1) The stretching exercise machine 10 of the above embodiment includes: a main body 11 having a pressing mechanism 30 for pressing the body of the user U; a pair of shoulder hanging parts 12a, 12b extending from the main body 11 and hanging on the left and right shoulders S1, S2 of the user U; and a pair of fastening parts 13a, 13b for fastening the pair of shoulder hanging parts 12a, 12b to the left and right shoulders S1, S2 of the user U respectively. The stretching exercise machine 10 of this embodiment is a stretching exercise machine used by wearing the main body 11 on the back B of the user U. In the stretching exercise machine 10 of this embodiment, when a pair of shoulder hanging parts 12a and 12b are fastened to the left and right shoulders S1 and S2 of the user U using a pair of fastening parts 13a and 13b, the main body 11 is worn from the left and right shoulders S1 and S2 of the user U to the back B, and a pressing mechanism 30 is provided at the position of the treatment part X that can press the area between the left and right scapulae K1 and K2 in the back B of the user U.

[0153] With the main body 11 fixed to the user U's shoulder S, the stretching exercise machine 10 can press the user U's back B using the pressing mechanism 30. In this case, the same effect as stretching the user U's left and right shoulders S towards the back B and inward can be obtained. Therefore, the stretching exercise machine 10 with this structure can stretch the muscles of the back B and obtain a stretching effect.

[0154] (2) In the stretching exercise machine 10 of the above embodiment, the pressing mechanism 30 includes an air bladder 40 that can expand and contract by means of air inlet and outlet.

[0155] The stretching exercise machine 10 with this structure can press the back B of the user U by inflating the airbag 40 by supplying air to it. With this structure, the structure of the pressing mechanism 30 can be simplified, and the stretching exercise machine 10 can be constructed in a lightweight and compact manner.

[0156] (3) The stretching exercise machine 10 of the above embodiment also has a drive mechanism 50 for driving the pressing mechanism 30. In the stretching exercise machine 10 of the above embodiment, the drive mechanism 50 includes: a pump 51 for allowing air to enter and exit the air bag 40; and an air pipe (piping component) 53 for connecting the air bag 40 and the pump 51.

[0157] The stretching machine 10 with this structure can easily form a drive mechanism 50 for driving the pressing mechanism 30. With this structure, the stretching machine 10 can be constructed in a lightweight and compact manner.

[0158] (4) In the stretching exercise machine 10 of the above embodiment, the drive mechanism 50 further includes a battery 52 for driving the pump 51, and the shoulder part 12 has a receiving part 18 capable of accommodating at least one of the pump 51 and the battery 52.

[0159] The stretching exercise machine 10 with this structure can accommodate the pump 51 and the battery 52 in the shoulder strap 12. With this structure, the user U can move freely while wearing the stretching exercise machine 10.

[0160] (5) In the second stretching exercise machine 10B of the above embodiment, the airbag 40 includes at least one of the first airbag 41 and the second airbag 42. The first airbag 41 presses the first treated part X1, which includes the lower part of the treated part X, and the second airbag 42 presses the second treated part X2, which includes the area of ​​the treated part X that is higher than the first treated part X1.

[0161] The second stretching machine 10B with this structure allows the user to select a point on their back B to be pressed by the airbag 40 from either the lower first treatment area X1 or the upper second treatment area X2, or both. With this structure, the user U can select the location on their back B to be pressed by the airbag 40 according to their preference.

[0162] (6) In the third stretching exercise machine 10C of the above embodiment, the airbag 40 includes at least one of the third airbag 43 and the fourth airbag 44. The third airbag 43 presses the third treated part X3, which includes a region on the left side of the treated part X that is further to the left than the center in the left-right direction. The fourth airbag 44 presses the fourth treated part X4, which includes a region on the right side of the treated part X that is further to the right than the center in the left-right direction.

[0163] The third stretching exercise machine 10C with this structure allows the user to select a location on the back B to be pressed by the airbag 40 from either the third treatment area X3 on the left side of the back B or the fourth treatment area X4 on the right side of the back B, or both the third treatment area X3 and the fourth treatment area X4. With this structure, the location on the back B to be pressed by the airbag 40 can be selected according to the user U's preference.

[0164] (7) In the stretching exercise machine 10 of the above embodiment, the main body 11 includes: a first fabric member 15a having a first surface 15c opposite to the back B of the user U when worn on the back B, and a second surface 15d opposite to the first surface 15c; and a plate-shaped core material 16 disposed facing the second surface 15d. In the stretching exercise machine 10 of the above embodiment, an airbag 40 is disposed between the first fabric member 15a and the core material 16.

[0165] The stretching motion machine 10 with this structure can limit the expansion of the airbag 40 towards the core material 16 side by the core material 16. With this structure, the pressure of the airbag 40 can be prevented from escaping beyond the back B side, thereby reliably applying the pressing pressure based on the pressing mechanism 30 to the back B of the user U.

[0166] (8) In the stretching exercise machine 10 of the above embodiment, the main body 11 also has a protrusion 60 that can be provided on the first surface 15c.

[0167] The stretching machine 10 with this structure can apply pressure based on the expansion of the airbag 40 to the back B of the user U locally via the protrusion 60. As a result, the pressure applied to the back B of the user U can be locally concentrated and increased.

[0168] (9) In the stretching exercise machine 10 of the above embodiment, the main body 11 also has a pocket 70 provided on the first surface 15c and capable of accommodating the protrusion 60.

[0169] The stretching machine 10 with this structure allows the protrusion 60 to be easily provided on the first surface 15c by accommodating the protrusion 60 in the pocket portion 70. Furthermore, by changing the position of the protrusion 60 inside the pocket portion 70, the pressing position based on the protrusion 60 can be easily changed.

[0170] (10) In the second stretching exercise machine 10B of the above embodiment, the main body 11 has a plurality of pockets 70 (first pocket 71 and second pocket 72). In addition, in the third stretching exercise machine 10C of the above embodiment, the main body 11 has a plurality of pockets 70 (third pocket 73 to sixth pocket 76).

[0171] According to the second stretching machine 10B with this structure, the pocket portion 70 that accommodates the protrusion 60 can be selected from among a plurality of pocket portions 70 (first pocket portion 71 and second pocket portion 72). Furthermore, according to the third stretching machine 10C with this structure, the pocket portion 70 that accommodates the protrusion 60 can be selected from among a plurality of pocket portions 70 (third pocket portion 73 to sixth pocket portion 76). Thus, the position of the back B pressed by the protrusion 60 can be easily changed according to the user U's preference.

[0172] The embodiments have been described above, but it should be understood that various changes in manner or details can be made without departing from the spirit and scope of the claims.
