[0020] Hereinafter, embodiments of the present invention will be described with reference to the drawings. The embodiment is an example of a specific embodiment of the present invention, and the configuration of the present invention is not limited to this specific example.

[0021] The massage machine 1 of this embodiment is a shoulder-type massage machine that is worn over the shoulders of a user P and is mainly used to massage the neck, shoulders, etc. of the user P. The massage machine 1 of this embodiment can also massage the waist, legs, etc. of the user P by changing the contact position of the main body 2.

[0022] As shown in Figs. 1 to 4, the massage machine 1 includes a main body 2, a shoulder strap 3, and a belt 4. As shown in Figs. 1 and 2, the main body 2 includes a massage mechanism 5. The massage mechanism 5 is built into the main body 2, and massages the shoulder and surrounding areas to be treated by placing the treatment section 2S of the main body 2 against the shoulder of the user P and driving the treatment section 2S. The detailed configuration of the massage mechanism 5 will be described later.

[0023] 5 to 7, in this embodiment, the direction corresponding to the front-to-back direction of the user P in a basic posture in which the massager is properly worn by the user P (the direction indicated by arrows X1 and X2 in FIGS. 1 and 4) will be described as the front-to-back direction of the massager 1, the direction corresponding to the left-to-right direction of the user P in the same posture (the direction indicated by arrows Y1 and Y2 in FIGS. 1 to 3) will be described as the left-to-right direction of the massager 1, and the direction corresponding to the up-to-down direction of the user P in the same posture (the direction indicated by arrows Z1 and Z2 in FIGS. 1 to 4) will be described as the up-to-down direction of the massager 1. Furthermore, the massager 1 of this embodiment has many flexibly deformable parts such as the shoulder strap part 3 and the belt part 4, and the arrangements, extension directions, etc. of these parts will also be described based on the state of the basic posture.

[0024] 1 and 2, the shoulder straps 3 are respectively provided extending from the left and right ends of the main body 2. In other words, the body of the massage machine 1 is configured in a U-shape by the main body 2 and the pair of left and right shoulder straps 3. As a result, when the massage machine 1 is worn by the user P with the left and right shoulder straps 3 hung on the shoulders of the user P, the treatment sections 2S of the main body 2 can be held in appropriate contact with the shoulders and the surrounding treatment areas.

[0025] 1 to 4, the shoulder straps 3 are formed integrally with the main body 2 and extend like legs from the left and right ends of the main body 2. The shoulder straps 3 extend downward and forward from the left and right ends of the main body 2 and are arranged side by side in the left-right direction at a distance wider than the neck of the user P (see FIG. 5).

[0026] The main body 2 and the shoulder strap 3 have an exterior cover and cushioning material. The exterior cover is made of a flexible fabric such as artificial leather or mesh fabric. The cushioning material is made of an elastic material such as urethane. The cushioning material is placed inside the exterior cover, excluding the storage area for the massage mechanism 5 and some areas such as the treatment unit 2S. Therefore, the shoulder strap 3 has shape retention, but can be bent within a predetermined range. In other words, the shoulder strap 3 is bendable. This allows the massage machine 1 to be easily worn by the user P by bending the left and right shoulder straps 3 outward to the left and right (widening the gap between the shoulder straps 3).

[0027] The shoulder strap 3 of this embodiment has a bendable portion 3G in a middle portion 3D between the distal end 3E and the proximal end 3F. The bendable portion 3G has higher bendability than the distal end 3E and the proximal end 3F. Therefore, as shown in Fig. 8, when the distal end 3E of the shoulder strap 3 is lifted, the bendable portion 3G allows the distal end 3E to bend in the vertical direction.

[0028] As shown in Figure 3, the shoulder strap 3 has a belt insertion hole 13. is a slit that is long in the left-right direction and penetrates in the front-rear direction at the center between the left and right of the middle portion 3D. A tightening belt 8, which will be described later, is inserted into the belt insertion hole 13 from the rear of the shoulder strap portion 3 and engages with a tightening adjuster 9 arranged on the front surface of the shoulder strap portion 3 (see FIG. 4). The engagement state of the tightening belt 8 with the tightening adjuster 9 will be described in detail later.

[0029] As shown in Figures 1, 2, and 4, the shoulder strap 3 has a shape-retaining member 14. The shape-retaining member 14 is a substantially rectangular plate made of a synthetic resin material, such as polyethylene, that is harder than the cushioning material. The shape-retaining member 14 is fitted inside the tip 3E of the shoulder strap 3 and maintains the tip 3E in a substantially rod-like shape. Therefore, when the user P grasps the tip 3E of the shoulder strap 3, the user P feels a certain grip. Furthermore, since the shape-retaining member 14 is housed in the tip 3E, the shoulder strap 3 is easily bent at the bendable portion 3G when the tip 3E is lifted.

[0030] The shoulder straps 3 have loops 15. The loops 15 are provided on both the left and right shoulder straps 3. The loops 15 are provided on the front of the shoulder straps 3 and hold the fastening adjuster 9 suspended therefrom. In this embodiment, the loops 15 are provided on the front of the intermediate portion 3D of the shoulder straps 3. The fastening adjuster 9 is suspended and held by the loops 15.

[0031] As shown in FIGS. 1, 2, and 5, one of the left and right shoulder straps 3 (the left shoulder strap 3 in this embodiment) has an operating unit C1. The operating unit C1 is connected to the massage mechanism 5 via a control circuit. The user P operates the massage mechanism 5 using the operating unit C1. The massage mechanism 5 is driven by power supplied from a battery built into the main body 2 or the shoulder strap 3. The battery, control circuit, etc. may be stored within the shape-retaining member 14. The massage mechanism 5 may also be configured to be driven by power supplied from an external power source via a power cable.

[0032] The massage mechanism 5 can be any mechanism capable of performing various massages, such as kneading massage, grasping massage, and tapping massage, as long as it can appropriately massage the neck, shoulders, etc. of the user P. For example, the massage machine 1 of this embodiment can employ the mechanism disclosed in Japanese Patent Application Laid-Open No. 2018-029722 as the massage mechanism 5. Alternatively, the massage machine 1 of this embodiment may employ the mechanism disclosed in Japanese Patent Application Laid-Open No. 2013-031567 as the massage mechanism 5.

[0033] As shown in FIG. 9 , in this embodiment, the massage mechanism 5 includes a drive unit 50, a first massage mechanism 51, a second massage mechanism 52, and a power transmission mechanism 53. The drive unit 50 generates a rotational drive force. The first massage mechanism 51 performs a first massage (in this embodiment, a kneading massage and a grasping massage) on the treatment area of ​​the user P. The second massage mechanism 52 performs a second massage (in this embodiment, a tapping massage) different from the first massage on the treatment area of ​​the user P. The power transmission mechanism 53 transmits the rotational drive force of the drive unit 50 to both the first massage mechanism 51 and the second massage mechanism 52, or to only the first massage mechanism 51. In other words, the massage mechanism 5 is configured to perform a variety of massages by simultaneously or selectively driving the two massage mechanisms 51 and 52 using a single drive unit 50.

[0034] The massage mechanism 5 has a plurality of kneading treatment elements T1 and gripping treatment elements T2. The first massage mechanism 51 performs a kneading massage by operating the kneading treatment elements T1 to press against the area to be treated. The first massage mechanism 51 also performs a gripping massage by operating the kneading treatment elements T1 and gripping treatment elements T2 to sandwich the area to be treated between them.

[0035] Specifically, the first massage mechanism 51 operates the kneading treatment elements T1 and the gripping treatment elements T2 to move closer to or farther away from each other, narrowing or widening the gap between the kneading treatment elements T1 and the gripping treatment elements T2. As a result, the first massage mechanism 51 performs a massage (grasping massage) by pinching the treatment area. The second massage mechanism 52 operates the kneading treatment elements T1 to hit the treatment area at short intervals, thereby performing a hitting massage.

[0036] By performing each of the above massage operations, the massage mechanism 5 receives a reaction force from the area to be treated and generates a force component that moves the main body 2 in the up and down direction. In particular, when the massage mechanism 5 operates to sandwich the shoulders of the user P from the front and back between the kneading treatment elements T1 and the gripping treatment elements T2 as described above, that is, when the distance between the kneading treatment elements T1 and the gripping treatment elements T2 is narrowed, a force component that lifts the main body 2 from the shoulders of the user P is generated.

[0037] As shown in Figs. 1 to 4, the belt portion 4 has a waist belt 7, a tightening belt 8, and a tightening adjustment tool 9. The belt portion 4 extends from the main body portion 2 to the shoulder strap portion 3. As shown in Figs. 6 and 7, when the massage machine 1 is worn by a user P, the belt portion 4 extends from the main body portion 2 to the back side of the user P, passes under the armpits of the user P, and reaches the shoulder strap portion 3. In this state, by tightening the belt portion 4 around the waist of the user P, the body portion of the massage machine 1, including the main body portion 2 and the shoulder strap portion 3, is held and fixed on the shoulders of the user P.

[0038] More specifically, the belt part 4 forms a loop-shaped armhole between the shoulder strap part 3 (under the main body part 2), and by putting the user P's arm through the armhole and tightening it, the shoulder strap part 3 is placed on the user P's shoulder and the main body part 2 (treatment part 2S) is placed against the part to be treated (in this embodiment, the shoulder of the user P), and the main body part 2 is fixed to the user P. In this way, by passing under the armpits of the user P, the belt part 4 prevents the main body part 2 from floating up when the massage mechanism 5 is driven.

[0039] As shown in FIGS. 3 and 6, the waist belt 7 is a band formed in an inverted Y-shape or an inverted T-shape when viewed from the rear, and includes a vertical band portion 11 and a horizontal band portion 12. The waist belt 7 includes an outer cover made of the same material as the outer cover of the main body portion 2, and a bendable plate-shaped core material. Therefore, the waist belt 7 has shape retention, but can be bent within a predetermined range. In other words, the waist belt 7 is bendable. As a result, a part of the waist belt 7 (for example, the horizontal band portion 12) is positioned along the contours of the user P's back when the massage machine 1 is worn on the user P (see FIGS. 6 and 7).

[0040] More specifically, as shown in Fig. 6, in this embodiment, the waist belt 7 has the vertical belt portion 11 positioned between the left and right shoulder blades of the user P, and the horizontal belt portion 12 positioned along the lower parts of the left and right shoulder blades of the user P so as to support the left and right shoulder blades from below. In other words, the waist belt 7 is positioned around the shoulder blades of the user P. This allows the main body portion 2 to be stably supported and fixed to the shoulders of the user P. Therefore, the massage machine 1 will not easily fall off the user P even if the user P moves slightly.

[0041] The vertical belt portion 11 extends rearward and downward from the center between the left and right sides of the main body portion 2. In this embodiment, the vertical belt portion 11 extends rearward and downward from the upper part of the main body portion 2 (more specifically, from the top of the main body portion 2 when the massage machine 1 is properly worn on the user P). Therefore, when the waist belt 7 is pulled downward and a downward force is applied to the vertical belt portion 11, the main body portion 2 is pressed forward and downward (in this embodiment, in the extension direction of the shoulder strap portion 3) by the vertical belt portion 11. In other words, the force when the side end portion 12E of the waist belt 7 is pulled toward the shoulder strap portion 3 is applied to the center between the left and right sides of the main body portion 2. This allows the treatment section 2S (particularly the gripping treatment element T2) of the main body 2 to be pressed more appropriately against the shoulder of the user P (the part to be treated).

[0042] As shown in FIGS. 1, 3, and 4, the vertical belt portion 11 is inserted into a belt loop 16 provided at the upper part of the main body portion 2. More specifically, the main body portion 2 has the belt loop 16. The belt loop 16 is a band extending in the left-right direction, and only both ends are attached to the main body portion 2, allowing the vertical belt portion 11 to be inserted between the center of the belt loop 16 and the main body portion 2. The belt loop 16 is provided at the middle or lower part of the main body portion 2, perpendicular to the direction in which the vertical belt portion 11 extends. The belt loop 16 is provided laterally at a position rearward of the upper end of the vertical belt portion 11 (the connection between the vertical belt portion 11 and the main body portion 2). In other words, the vertical belt portion 11 is held down from above by the belt loop 16 at a position rearward of the upper end. This prevents the vertical belt portion 11 from floating up from the main body portion 2 when worn, so that the force generated when the side end portion 12E of the waist belt 7 is pulled toward the shoulder portion 3 can be more reliably transmitted to the upper part of the main body portion 2. This allows the main body 2 to be attached to the user P more stably.

[0043] The horizontal belt portion 12 is integrally formed with the lower end of the vertical belt portion 11. The horizontal belt portion 12 extends in the left-right direction from the lower end of the vertical belt portion 11. In other words, the vertical belt portion 11 is connected to the center between the left and right of the horizontal belt portion 12. In this way, the waist belt 7 extends downward and rearward from the main body portion 2 and further extends forward on the left and right sides.

[0044] 1 to 4, the tightening belt 8 is connected to the side end 12E of the horizontal belt 12 (waist belt 7). The tightening belt 8 is a flexible belt made of nylon or the like, and extends forward from the side end 12E of the horizontal belt 12 when the massage machine 1 is in the basic position worn by the user P.

[0045] The tightening belt 8 passes through the belt insertion hole 13 from the rear of the shoulder strap 3 and engages with the distal end frame 24 of the tightening adjustment tool 9. Then, the tightening belt 8 is again inserted through the belt insertion hole 13 from the front of the shoulder strap 3, and is held in a suspended state below the belt insertion hole 13 on the rear side of the shoulder strap 3 by its own weight.

[0046] Therefore, when the leading end of the tightening belt 8 is pulled downward in the extension direction (vertically downward of the main body 2, in the extension direction of the shoulder strap 3, or below the user P), the base end (the end connected to the waist belt 7) is pulled in conjunction with this and toward the belt insertion hole 13. In other words, the side end 12E of the horizontal band 12 (waist belt 7) is pulled toward the rear of the shoulder strap 3 as the tightening belt 8 is pulled.

[0047] In this embodiment, the belt insertion hole 13 is formed with a width dimension that allows the belt surface of the tightening belt 8 to contact the inner surface of the belt insertion hole 13. In other words, the belt insertion hole 13 provides a predetermined contact resistance to the tightening belt 8.

[0048] The fastening adjuster 9 is provided at the midpoint 3D of the shoulder strap 3. As shown in Fig. 4, the fastening adjuster 9 is disposed in front of the belt insertion hole 13, sandwiching the shoulder strap 3. As shown in Figs. 1, 2 and 4, the fastening adjuster 9 is connected to and held by a loop 15 provided on the front surface of the shoulder strap 3.

[0049] More specifically, as shown in Figures 10 and 11, the tightening adjustment tool 9 has a support end frame portion 21, a middle frame portion 22, an engagement frame portion 23, and a tip frame portion 24. The support end frame portion 21 is formed in the shape of a cylindrical shaft that is long in the left-right direction, and constitutes the upper side (first side) of the tightening adjustment tool 9. The support end frame portion 21 is inserted into the loop portion 15 of the shoulder strap portion 3, and is inserted and held by the loop portion 15 so as to be rotatable. In other words, the tightening adjustment tool 9 is supported by the shoulder strap portion 3 with the support end frame portion 21 as a fulcrum. The shafts are connected and supported so as to be rotatable.

[0050] The tightening adjuster 9 is suspended and held facing the front surface of the shoulder strap 3. Therefore, as shown in Figure 11, when the tip 3E of the shoulder strap 3 is lifted, the tip frame 24 of the tightening adjuster 9 is pushed forward, causing it to swing forward and upward with the support end frame 21 as a fulcrum.

[0051] As shown in Figures 10 and 11, the middle frame portion 22 is formed in a generally flat plate shape that is long in the left-right direction, and is arranged below the support end frame portion 21 with a predetermined gap. The engagement frame portion 23 is arranged below the middle frame portion 22 with a predetermined gap. The engagement frame portion 23 is formed in a generally rectangular columnar shaft shape that is long in the left-right direction. The tightening belt 8 is engaged and held by the engagement frame portion 23.

[0052] 10, the tightening belt 8 is inserted from the rear into the gap between the middle frame portion 22 and the engaging frame portion 23, passes around the front outer periphery of the engaging frame portion 23, and is then inserted from the front into the gap between the engaging frame portion 23 and the tip frame portion 24. As a result, the tightening belt 8 is held in a state where it is bent in a U-shape relative to the engaging frame portion 23.

[0053] The tip frame 24 forms the lower side (second side) of the tightening adjustment tool 9. The tip frame 24 has anti-slip portions 25. The anti-slip portions 25 are small tooth-like protrusions, and multiple anti-slip portions 25 are arranged side by side on the left and right along the rear upper edge of the tip frame 24. When the tightening adjustment tool 9 is in a basic position with the tip frame 24 facing downward, the anti-slip portions 25 press against and engage with the band surface of the tightening belt 8 inserted into the gap between the engagement frame 23 and the tip frame 24. This causes the tightening belt 8 to enter a tensioned state in which movement in the extension direction is prevented. In other words, movement of the tightening belt 8 in the extension direction is prevented by contact resistance with the belt insertion hole 13, contact resistance with the engagement frame 23, and contact resistance with the anti-slip portions 25.

[0054] Furthermore, in this state, if the tightening belt 8 is pulled downward as described above, the tightening belt 8 is held by the anti-slip portion 25 in a state in which the waist belt 7 (the side end 12E of the horizontal band portion 12) is pulled further toward the shoulder portion 3. As a result, the belt portion 4 is fitted more tightly around the waist of the user P. In other words, by pulling the tightening belt 8 downward, the tightening adjuster 9 holds the belt portion 4 in a state in which it is firmly fastened around the waist of the user P. This allows the main body portion 2 to be fixed to the user P more stably.

[0055] 11, when the tightening adjustment tool 9 is in a position where the distal end frame 24 is raised forward, the anti-slip portion 25 moves away from the band surface portion of the tightening belt 8. As a result, the tightening belt 8 enters a relaxed state where it is allowed to move in the extension direction, and the tightening state of the belt portion 4 on the user P is released. This allows the user P to easily remove the massage machine 1.

[0056] As described above, when the distal end frame 24 of the tightening adjustment tool 9 is oriented downward, it is in a tensioned state that prevents movement of the tightening belt 8 in the extension direction (see FIG. 10). Conversely, when the distal end frame 24 is oriented forward and raised, the tightening adjustment tool 9 is in a relaxed state that allows movement of the tightening belt 8 in the extension direction (see FIG. 11). In other words, the tightening adjustment tool 9 allows tension and relaxation of the tightening belt 8 in the extension direction.

[0057] As shown in Figs. 1 to 4, the belt portion 4 has a protective pad 17. The protective pad 17 has a cover body and a cushioning material (a shock-absorbing member). The cover body is made of a flexible material such as artificial leather or mesh fabric. The cushioning material is made of an elastic material such as urethane. The cushioning material is filled inside the cover body. In other words, the protective pad 17 is a pad with cushioning properties.

[0058] In this embodiment, the protective pad 17 is configured by joining two substantially oval pad members together at their long edges. The tightening belt 8 is inserted into the gap between the two pad members. In other words, the protective pad 17 is attached so that the tightening belt 8 is sandwiched between the two pad members. This allows the protective pad 17 to slide along the tightening belt 8 within a predetermined range in the extension direction of the tightening belt 8.

[0059] As shown in Figures 6 and 7, the protective pads 17 are placed on the sides of the user P when the massage machine 1 is worn by the user P. In other words, the protective pads 17 become pad portions that elastically contact the sides of the user P when worn. This prevents the tightening belts 8 from directly contacting the sides of the user P and the surrounding area, providing a comfortable feel.

[0060] As shown in FIGS. 1 to 4, the tightening belt 8 has a handle 18. The handle 18 is provided at the tip of the tightening belt 8. In this embodiment, the handle 18 is a ring that is wider than the tightening belt 8 and has a substantially rectangular annular shape. Therefore, when wearing the massage machine 1, the user P can grasp the handle 18 with their hand and pull the tightening belt 8. Alternatively, the user P can grasp the tip of the tightening belt 8 with their hand or fingertips hooked on the handle 18 and pull the tightening belt 8.

[0061] As described above, the handle 18 is formed in a generally rectangular ring shape that is wider than the tightening belt 8, making it easy to place your hand on it. Furthermore, since a large grip strength is not required to pull the tightening belt 8 and your hand will not slip off the tightening belt 8, even a user P with a weak grip strength can press the main body 2 (massage mechanism 5) firmly against the area to be treated. This makes it easy to use.

[0062] Furthermore, since the tightening belt 8 has a handle 18 at its tip, even if it is loosened and pulled in the opposite direction from the tip as described above, it will not come off from the tightness adjustment tool 9 and the belt insertion hole 13. In other words, the handle 18 functions as a retaining member that prevents the tightening belt 8 from coming off from the tightness adjustment tool 9 and the belt insertion hole 13. Moreover, the handle 18 also serves as a guide when the user P grasps the tightening belt 8.

[0063] In this embodiment, the handle 18 is configured as a separate member from the tightening belt 8, but the handle 18 may be formed integrally with the tip of the tightening belt 8. For example, the handle 18 may be formed in a loop shape by folding back the tip of the tightening belt 8, or may be a hole formed through the tip of the tightening belt 8.

[0064] Furthermore, the shape of handle 18 is not limited to a rectangular ring shape, as long as it can properly pull fastening belt 8. For example, handle 18 may be formed in a circular ring shape or a spherical shape. Alternatively, handle 18 may be formed in a T-shape or a rod shape.

[0065] 12, the handle 18 may be formed in a cylindrical shape that is longer than the width of the tightening belt 8. With this configuration, it is possible to achieve a lighter weight and improved design while still retaining basic functions such as preventing the hand from slipping when pulling the tightening belt 8, preventing the tightening belt 8 from slipping out of the tightening adjuster 9 and the belt insertion hole 13 when the tightening belt 8 is loosened, and providing a mark when gripping the tightening belt 8.

[0066] <Modification> In the above embodiment, the massage machine 1 is configured to be attached and fixed to the user P by a waist belt 7 and a tightening belt 8, but as shown by the dotted line in Figures 5 and 7, the belt portion 4 may also include a chest belt 60 in addition to the waist belt 7, tightening belt 8, and tightening adjustment device 9.

[0067] The chest belt 60 has a connecting belt 61 and a buckle 62. Similar to the tightening belt 8, the connecting belt 61 is a flexible band made of nylon or the like, and extends forward from each of the left and right side end portions 12E of the horizontal belt portion 12 (see FIG. 7). Therefore, when the massage machine 1 is worn by the user P, the connecting belt 61 passes under the left and right armpits of the user P and reaches the chest side.

[0068] The buckle 62 is provided at the tip of the connecting belt 61. The buckle 62 is a fastener that can be freely separated and connected using a snap-fit ​​structure. In other words, the buckle 62 is a fastener that has a pair of male and female connecting halves (e.g., a claw piece and a claw receiving portion) and can connect the two connecting halves together using the elasticity of at least one of the connecting halves (e.g., the claw piece). Therefore, the tips of the left and right connecting belts 61 can be easily separated and connected together using the buckle 62.

[0069] The massage machine 1 of this embodiment can be fixed to the user P using the chest belt 60 in addition to the waist belt 7 and the tightening belt 8, so that it can be more stably attached to the user P. This makes it more difficult for the massage machine 1 to fall off the user P, and can provide even better usability.

[0070] In the above embodiment, the waist belt 7 is formed in an inverted Y-shape or an inverted T-shape when viewed from behind, but as long as the massage machine 1 can be stably attached to the user P, it may have a shape other than the above, such as being formed in an approximately H-shape when viewed from behind, or the vertical belt portion 11 being formed in an approximately V-shape when viewed from behind, or a wide I-shape (wide strip shape).

[0071] In the above embodiment, the waist belt 7 is connected to the main body 2 by sewing the upper ends of the vertical belt portions 11 to the main body 2, but it may also be removably connected to the main body 2. More specifically, the upper ends of the vertical belt portions 11 of the waist belt 7 are connected to the main body 2 by connecting members such as slide fasteners or snap buttons. Preferably, the waist belt 7 is connected to the main body 2 by slide fasteners so that it does not easily come off when pulled downward.

[0072] The handle 18 is formed by folding back the tip of the tightening belt 8 and bending it into a loop, and the tightening belt 8 can be removed from the tightness adjustment tool 9 by pulling it in the extension direction opposite to the tip. In other words, the waist belt 7 can be separated from the main body 2 and the shoulder strap 3 by releasing the engagement state of the slide fastener and removing the tip of the tightening belt 8 from the tightness adjustment tool 9. In this way, by removing the waist belt 7 from the main body 2 and the shoulder strap 3, the style of use can be changed to suit the preference of the user P, thereby improving versatility.

[0073] In the above embodiment, the protective pad 17 is configured to be slidable along the tightening belt 8 and is configured so that its position can be adjusted arbitrarily depending on the wearing posture of the massage machine 1 and the body shape of the user P, but the protective pad 17 may also be connected to the shoulder strap portion 3.

[0074] More specifically, for example, the front end (the end on the shoulder strap 3 side) of the protection pad 17 is connected and fixed to the edge of the opening of the belt insertion hole 13 on the rear surface of the shoulder strap 3. In other words, the protection pad 17 extends from the rear surface of the shoulder strap 3 toward the armpits of the user P. In this case, when the user P wears the massage machine 1 as described above, the protection pad 17 is attached to the armpits of the user P. This improves usability as there is no need to adjust the position.

[0075] As such, the massage machine 1 of this embodiment is a massage machine comprising a main body 2 equipped with a massage mechanism 5 that massages the treatment area including the shoulders of the user P, and a pair of shoulder straps 3 extending to the left and right of the main body 2, and is provided with a belt 4 that is passed under the armpits of the user P to secure the main body 2 to the user P while the main body 2 is in contact with the treatment area, and the belt 4 has a tightening adjustment device 9 provided on the shoulder strap 3 that allows the belt 4 to be tightened and loosened relative to the user P, and the tightening adjustment device 9 is configured to loosen the belt 4 as the tip 3E of the shoulder strap 3 is lifted.

[0076] According to this massage machine 1, the main body 2 can be attached and fixed to the user P as if worn on the back using the belt portion 4, allowing the user P to massage the area to be treated in a hands-free state. In other words, the user P can use both hands freely even during the massage. This makes it possible to realize a massage machine 1 that is easy to use. Furthermore, with this massage machine, the shoulder strap portion 3 and the belt portion 4 form a loop-shaped arm hole at the bottom of the main body 2, and the user P passes their arms through the arm hole and fixes the main body 2 to the user P as if worn on the back, so there is no problem with the main body 2 floating up from the area to be treated.

[0077] Moreover, with this massage machine 1 attached to the user P, lifting the tip 3E of the shoulder strap 3 loosens the belt 4, releasing it from its tight state on the user P. This allows the massage machine 1 to be easily removed from the user P without any hassle, making it possible to realize a massage machine 1 that is even easier to use.

[0078] Furthermore, with this device, the degree of pressure of the main body 2 against the area to be treated can be adjusted by pulling or loosening the tightening belt 8 as described above. In other words, the strength of the massage can be adjusted by changing the degree of tightening of the tightening belt 8. This further improves usability.

[0079] The shoulder strap portion 3 has a bendable portion 3G that allows the tip portion 3E to bend in the vertical direction, and the tightening adjustment device 9 loosens the belt portion 4 as the tip portion 3E is lifted and bent upward.

[0080] According to this massage machine 1, when the massage machine 1 is worn by the user P, bending the tip end 3E of the shoulder strap portion 3 upward loosens the belt portion 4, and the tightened state of the belt portion 4 around the user P is released. In other words, when the user P holds the tip end 3E of the shoulder strap portion 3 and takes the main body portion 2 off his / her shoulder, the tightened state of the belt portion 4 around the user P is released. This allows the massage machine 1 to be more easily removed from the user P. This further improves usability.

[0081] The shoulder strap portion 3 has a shape-retaining member 14 that maintains the tip portion 3E in a predetermined shape.

[0082] According to this massage machine 1, the tip 3E of the shoulder strap 3 has shape retention, so that when the tip 3E is lifted, the bendable portion 3G bends more smoothly. This allows the tightened state of the belt 4 to be released more smoothly. This further improves usability.

[0083] The belt portion 4 includes a waist belt 7 extending downward from the main body portion 2 toward the rear, and a fastening adjustment tool 9 extending from the waist belt 7 to the lower side of the shoulder portion 3, and is pulled in the extending direction. The tightening adjustment device 9 allows the tightening belt 8 to move in the direction of extension, that is, the tip end, and prevents it from moving in the direction of the base end, that is, the opposite direction to the tip end.

[0084] With this massage machine 1, when the tightening belt 8 is pulled, the waist belt 7 is pulled toward the shoulder strap portion 3, and the tightening belt 8 can be held in a tight state at that position, resulting in excellent wearability. Also, by loosening the tightening belt 8 with the tightening adjustment tool 9, the massage machine 1 can be easily removed from the user P. Therefore, usability is further improved.

[0085] Moreover, with this device, by pulling the tightening belt 8 in its extension direction and drawing the waist belt 7 toward the shoulder strap 3, the main body part 2 is pressed firmly against the area to be treated. In other words, the user P can simultaneously pull the tightening belt 8 to attach and fix the main body part 2 to the user P and press the main body part 2 against the area to be treated. This further improves usability.

[0086] The tightening adjustment tool 9 has a first side portion 21 extending in a direction that intersects perpendicularly with the extension direction of the tightening belt 8 (in the Y1, Y2 direction in Figure 1), and a second side portion 24 extending approximately parallel to the first side portion 21 at a predetermined interval, and the second side portion 24 has an anti-slip portion 25 that engages with the tightening belt 8 to prevent the tightening belt 8 from moving in the extension direction.

[0087] According to this massage machine 1, the movement of the tightening belt 8 in the extension direction is more reliably prevented by the anti-slip portion 27, so that better wearability can be obtained, and usability is further improved.

[0088] The shoulder strap portion 3 has a belt insertion hole 13 through which the tightening belt 8 is inserted, the tightening adjustment tool 9 is provided on the front portion of the shoulder strap portion 3, and the tightening belt 8 is connected to the tightening adjustment tool 9 from the rear portion of the shoulder strap portion 3 through the belt insertion hole 13.

[0089] According to this massage machine 1, by pulling the tightening belt 8, the waist belt 7 is smoothly pulled toward the rear surface (belt insertion hole 13) of the shoulder strap portion 3, thereby providing better wearing comfort. Therefore, usability is further improved.

[0090] The tightening belt 8 connected to the tightening adjustment tool 9 is configured to pass from the front part of the shoulder strap 3 through the belt insertion hole 13 to the rear part of the shoulder strap 3 .

[0091] According to this massage machine 1, when the tightening belt 8 is pulled, the tightening belt 8 is unlikely to interfere with the shoulder strap 3, so the waist belt 7 is more smoothly pulled toward the rear of the shoulder strap 3. Similarly, when the tightening belt 8 is loosened, the tightening belt 8 is unlikely to interfere with the shoulder strap 3, so the waist belt 7 is more smoothly pulled away from the rear of the shoulder strap 3. This further improves usability.

[0092] The belt portion 4 has a pad portion 17 that elastically contacts the armpit of the user P when worn.

[0093] According to this massage machine 1, by holding the pad portion 17 under the armpits, the main body portion 2 is held more stably by the user P, so that even in a hands-free state, the user can massage the area to be treated in a stable posture. This further improves usability. Moreover, with this massage machine, the tightening belt 8 does not come into direct contact with the body of the user P when worn, so , and provides a good usability.

[0094] The massage mechanism 5 is configured to exert a force with a directional component that lifts the main body part 2 off the shoulder when driven, and the belt part 4 passes under the armpit to prevent the main body part 2 from lifting up.

[0095] According to this massage machine 1, the main body 2 can be prevented from floating up during massage, so that the massage machine 1 can be made easier to use.

[0096] The tightening belt 8 has a retaining member 18 that prevents the tightening belt 8 from slipping out of the tightening adjuster 9 and the belt insertion hole 13 .

[0097] According to this massage machine 1, even if the tightening belt 8 is loosened, the tightening belt 8 does not come off the tightening adjustment tool 9 and the belt insertion hole 13, so the massage machine 1 can be prevented from unintentionally falling off the user P. This further improves usability.
