[0022] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Note that the embodiment described below 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.

[0023] The massage machine 1 of this embodiment is a massage machine that can be worn on the body of a user P when in use, and is used mainly to massage the neck, shoulders, and waist of the user P.

[0024] 1 to 4, the massage machine 1 includes a first main body 2A, a second main body 2B, a shoulder strap 3, a first attachment part 4A, a second attachment part 4B, and a connecting belt 4C. As shown in FIGS. 1 and 2, the first main body 2A includes a first massage mechanism 5A. The second main body 2B includes a second massage mechanism 5B.

[0025] The first massage mechanism 5A is built into the first main body 2A, and massages the shoulders and the surrounding area (first treatment area including the shoulders) by placing the treatment section (first treatment section) 2S of the first main body 2A against the shoulders of the user P and driving it. The second massage mechanism 5B is built into the second main body 2B, and massages the waist and the surrounding area (second treatment area including the waist) by placing the treatment section (second treatment section) 2T of the second main body 2B against the waist of the user P and driving it. The detailed configurations of the first massage mechanism 5A and the second massage mechanism 5B will be described later.

[0026] 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 attached to 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, the first attachment part 4A, and the second attachment part 4B, and the positions, extension directions, etc. of these parts will also be described based on the state of the basic posture.

[0027] As shown in Figures 1 and 2, the shoulder straps 3 are respectively provided at the left and right ends of the first main body 2A. In other words, the upper part of the massage machine 1 is configured in a U-shape by the first main body 2A and the pair of left and right shoulder straps 3. As a result, the massage machine 1 can be easily carried by the user P. On the other hand, by wearing the left and right shoulder strap parts 3 so that they are placed over the shoulders of the user P, the first treatment part 2S can be held in an appropriate position against the shoulders and their surroundings (first treatment part).

[0028] 1 to 4, the shoulder straps 3 are formed integrally with the first main body 2A and extend like legs from the left and right ends of the first main body 2A. The shoulder straps 3 extend downward and forward from the left and right ends of the first main body 2A 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).

[0029] The first main body 2A and the shoulder strap 3 have an exterior cover and cushioning material. The exterior cover 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 placed inside the exterior cover, excluding the storage area for the first massage mechanism 5A and some areas of the first 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).

[0030] The first massage mechanism 5A can be a 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 first massage mechanism 5A. Alternatively, the massage machine 1 of this embodiment may employ the mechanism disclosed in Japanese Patent Application Laid-Open No. 2013-031567 as the first massage mechanism 5A.

[0031] As shown in FIG. 8 , in this embodiment, the first massage mechanism 5A includes a drive unit 50, a first treatment mechanism 51, a second treatment mechanism 52, and a power transmission mechanism 53. The drive unit 50 generates a rotational driving force. The first treatment mechanism 51 performs a first massage (in this embodiment, a kneading massage and a grasping massage) on a first treatment area such as the neck or shoulders of the user P. The second treatment mechanism 52 performs a second massage (in this embodiment, a tapping massage) different from the first massage on the first treatment area. The power transmission mechanism 53 transmits the rotational driving force of the drive unit 50 to both the first treatment mechanism 51 and the second treatment mechanism 52, or to only the first treatment mechanism 51. In other words, the first massage mechanism 5A is configured to simultaneously or selectively drive the two treatment mechanisms 51 and 52 using a single drive unit 50, thereby performing a variety of massages.

[0032] The first massage mechanism 5A has a plurality of kneading treatment elements T1 and gripping treatment elements T2. The first treatment mechanism 51 performs a kneading massage by operating the kneading treatment elements T1 to press against the first treatment area. The first treatment mechanism 51 also performs a gripping massage by operating the kneading treatment elements T1 and the gripping treatment elements T2 to sandwich the first treatment area between them.

[0033] Specifically, the first treatment mechanism 51 operates the kneading treatment element T1 and the gripping treatment element T2 to move closer to or farther away from each other, narrowing or widening the distance between the kneading treatment element T1 and the gripping treatment element T2. As a result, the first treatment mechanism 51 performs a massage (grasping massage) by pinching the first treatment area. The second treatment mechanism 52 operates the kneading treatment element T1 to hit the first treatment area at short time intervals, thereby performing a hitting massage.

[0034] The first massage mechanism 5A performs the above-mentioned massage operations, and receives a reaction force from the first treatment area, thereby generating a component that moves the first main body portion 2A in the up and down direction. When the first massage mechanism 5A is operated as described above so that the kneading treatment element T1 and the gripping treatment element T2 pinch the shoulders of the user P from the front and back, that is, when the distance between the kneading treatment element T1 and the gripping treatment element T2 is narrowed, a force with a directional component that lifts the first main body portion 2A away from the shoulders of the user P is generated.

[0035] The second massage mechanism 5B can be a mechanism capable of performing various massages, such as kneading massage, grasping massage, and tapping massage, as long as it can appropriately massage the lower back and other parts 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. 2013-031567 as the second massage mechanism 5B. Alternatively, the massage machine 1 of this embodiment may employ the mechanism disclosed in Japanese Patent Application Laid-Open No. 2018-029722 as the second massage mechanism 5B.

[0036] As shown in FIGS. 1 and 2, in this embodiment, the second massage mechanism 5B has a drive unit, kneading balls 54, and a power transmission mechanism. The drive unit generates a rotational drive force. The kneading balls 54 are provided on the left and right sides of the center between the left and right sides of the second main body portion 2B, with a predetermined interval between them. The kneading balls 54 are protrusions that protrude forward. The tip ends of the kneading balls 54 are provided at positions radially eccentric from the center of rotation of the kneading balls 54. Therefore, when the kneading balls 54 are rotated, the tip ends rotate eccentrically with respect to the rotation axis of the kneading balls 54.

[0037] The power transmission mechanism transmits the rotational drive force of the drive unit to both the left and right massaging balls 54. The power transmission mechanism rotates the left and right massaging balls 54 in opposite directions. The power transmission mechanism reverses the rotation of the massaging balls 54 by switching the rotation direction of the drive unit from forward to reverse. In other words, the second massage mechanism 5B performs different massages on the second treatment area of ​​the user P by rotating the tip ends of the left and right massaging balls 54 in the forward or reverse direction using the drive unit.

[0038] The kneading balls 54 may have a heating element. The heating element generates heat by power supplied from a battery built into the massage machine 1 or power supplied from an external power source, and transfers the heat to the surfaces of the kneading balls 54. In this configuration, the second massage mechanism 5B heats the heating element and appropriately rotates the kneading balls 54, thereby performing thermal treatment on the second treatment area of ​​the user P.

[0039] 1 to 4, the first wearing part 4A has a waist belt 7, a tightening belt 8, and a tightening adjustment tool 9. As shown in FIGS. 5 to 7, the first wearing part 4A fixes the first main body part 2A to the user P with the shoulder strap part 3 hung on the shoulder of the user P and the first treatment part 2S in contact with the first treatment area.

[0040] As shown in Figs. 6 and 7, the first attachment part 4A is a belt member extending from the first main body part 2A to the shoulder part 3. More specifically, when the massage machine 1 is attached to the user P, the first attachment part 4A extends from the first main body part 2A to the back side of the user P, passes under the armpits of the user P, and reaches the shoulder part 3. Then, by pulling the fastening belt 8 in this state, the first attachment part 4A is fastened tightly to the torso of the user P. As a result, the upper part of the massage machine 1, including the first main body part 2A and the shoulder part 3, is held on the shoulders of the user P.

[0041] The first attachment part 4A forms a loop-shaped armhole between it and the shoulder strap part 3 (at the bottom of the first main body part 2A), and the user P's arm is passed through the armhole and fastened. As a result, the first attachment part 4A fixes the first main body part 2A to the user P with the shoulder strap part 3 hung on the shoulder of the user P and the first main body part 2A (first treatment part 2S) in contact with the first treatment part (in this embodiment, the shoulder of the user P). In this way, by passing under the armpit of the user P, the first attachment part 4A prevents the first main body part 2A from floating up when the first massage mechanism 5A is driven.

[0042] 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 first main body portion 2A, 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).

[0043] 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 first main body portion 2A 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.

[0044] The vertical belt portion 11 extends rearward and downward from the center between the left and right of the first main body portion 2A. In this embodiment, the vertical belt portion 11 extends rearward and downward from the upper portion of the first main body portion 2A (more specifically, from the top of the first main body portion 2A 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 first main body portion 2A is pressed forward and downward (in the extending direction of the shoulder strap portion 3 in this embodiment) by the vertical belt portion 11. In other words, the force generated when the side end portion 12E of the waist belt 7 is pulled toward the shoulder strap portion 3 is applied downward at the center between the left and right of the first main body portion 2A. This allows the first treatment portion 2S (particularly the gripping treatment element T2) of the first main body portion 2A to be more appropriately pressed against the shoulder (first treatment portion) of the user P.

[0045] As shown in Figures 3 and 4, the vertical belt portion 11 is inserted into a belt loop 13 provided on the upper part of the first main body portion 2A. More specifically, the first main body portion 2A has the belt loop 13. The belt loop 13 is a strip extending in the left-right direction, and both left and right ends thereof are connected to the first main body portion 2A. The vertical belt portion 11 is inserted between the left-right center of the belt loop 13 and the first main body portion 2A.

[0046] The belt loops 13 are provided at the middle or lower part of the first main body part 2A in the up-down direction, perpendicular to the direction in which the vertical belt part 11 extends. The belt loops 13 are provided laterally at a position rearward of the upper end of the vertical belt part 11 (the connection part between the vertical belt part 11 and the first main body part 2A). In other words, the vertical belt part 11 is held down from above by the belt loops 13 at a position rearward of the upper end. This prevents the vertical belt part 11 from floating up from the first main body part 2A when worn, so that the force generated when the side end part 12E of the waist belt 7 is pulled toward the shoulder part 3 can be more reliably transmitted to the upper part of the first main body part 2A. This allows the first main body part 2A to be worn more stably by the user P.

[0047] 2 and 3, 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 rearward and downward from the first main body portion 2A and further extends forward on the left and right sides.

[0048] 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.

[0049] The tightening belt 8 extends forward from the side end 12E of the horizontal band 12 and is inserted into a tightening adjustment tool 9 provided at the lower end of the shoulder strap 3. The tightening belt 8 then has its extension direction changed from forward to downward by the tightening adjustment tool 9, and is held suspended by its own weight below the shoulder strap 3.

[0050] Therefore, when the tip of the tightening belt 8 is pulled downward in the extension direction (vertically downward of the first main body portion 2A, in the extension direction of the shoulder portion 3, or below the user P), the base end (the end connected to the waist belt 7) is pulled in conjunction with this and is drawn toward the bottom end of the shoulder portion 3. In other words, as the tightening belt 8 is pulled, the side end 12E of the horizontal band portion 12 (waist belt 7) is drawn toward the bottom end of the shoulder portion 3. Furthermore, at this time, the tightening belt 8 can be pulled down without interfering with the side edges or bottom end of the shoulder portion 3, so the side end 12E of the horizontal band portion 12 (waist belt 7) is drawn smoothly toward the bottom end of the shoulder portion 3.

[0051] The tightening belt 8 has a handle portion 14. The handle portion 14 is provided at the tip of the tightening belt 8. In this embodiment, the handle portion 14 is configured as a separate member from the tightening belt 8. More specifically, the handle portion 14 in this embodiment is a ring that is wider than the tightening belt 8 and has a substantially circular shape, and is attached to the tip of the tightening belt 8. Therefore, when wearing the massage machine 1, the user P can grasp the handle portion 14 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 portion 14 and pull the tightening belt 8.

[0052] As described above, the handle 14 is formed in a circular ring shape that is wider than the tightening belt 8, so that the user can easily place his / her hand on it. Furthermore, a large grip strength is not required to pull the tightening belt 8, and the user's hand will not slip off the tightening belt 8, so even a user P with a weak grip strength can press the first main body portion 2A (first massage mechanism 5A) firmly against the first treatment area. This makes it easy to use.

[0053] Furthermore, since the tightening belt 8 has a handle 14 at its tip, it will not come off the tightness adjustment tool 9 even if it is loosened and pulled in the opposite direction from the tip as described above. In other words, the handle 14 functions as a retaining member that prevents the tightening belt 8 from coming off the tightness adjustment tool 9. Moreover, the handle 14 also serves as a guide when the user P grasps the tightening belt 8.

[0054] The shape of the handle 14 is not limited to a circular ring, as long as it can properly pull the fastening belt 8. For example, the handle 14 may be formed in a rectangular ring shape or a spherical shape. Alternatively, the handle 14 may be formed in a T-shape or a rod shape.

[0055] Furthermore, in this embodiment, the handle 14 is configured as a separate member from the tightening belt 8, but the handle 14 may be formed integrally with the tip of the tightening belt 8. For example, the handle 14 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.

[0056] The fastening adjuster 9 is provided at the tip 3E of the shoulder strap 3. More specifically, the shoulder strap 3 has a loop 15. The loop 15 is provided at the lower end of the shoulder strap 3 (the lower end of the tip 3E). The fastening adjuster 9 is held in a hanging state by the loop 15.

[0057] As shown in FIGS. 9 to 11, the tightening adjustment tool 9 has a support end frame portion 21, a middle frame portion 22, a first belt insertion hole 23, a second belt insertion hole 24, a direction change portion 25, and a tip frame portion 26. The support end frame 21 is formed in the shape of a cylindrical shaft that is long in the left-right direction, and is provided on the upper side of the fastening adjustment tool 9. The support end frame 21 is inserted into the loop portion 15 and is rotatably held by the loop portion 15. In other words, the fastening adjustment tool 9 is connected and supported to the shoulder strap part 3 so that it can rotate around the support end frame 21 as a fulcrum. Therefore, as shown in FIG. 11 , when the tip frame 26 is pulled forward, the fastening adjustment tool 9 swings forward and upward around the support end frame 21 as a fulcrum.

[0058] The middle frame portion 22 is a substantially flat frame body and is disposed horizontally in the vertical middle of the tightening adjustment tool 9. As shown in FIG. 9 , the upper side portion (upper oblique side portion) E1 of the middle frame portion 22 extends obliquely between the left and right side edges around the first belt insertion hole 23. In this embodiment, the upper side portion E1 extends obliquely downward from the outer side in the left-right direction of the massage machine 1 toward the center. Therefore, the tightening belt 8 inserted from the rear into the first belt insertion hole 23 comes into contact with the upper side portion E1 of the middle frame portion 22, whereby the tightening belt 8 is twisted by a predetermined angle and bent downward so as to be abducted. As a result, the tightening belt 8 is held in a more firmly tensed state relative to the tightening adjustment tool 9 by pulling it downward.

[0059] 9 to 11, the first belt insertion hole 23 and the second belt insertion hole 24 are both through holes with approximately the same width as the tightening belt 8. The first belt insertion hole 23 is defined between the support end frame portion 21 and the middle frame portion 22. The second belt insertion hole 24 is defined between the middle frame portion 22 and the tip frame portion 26.

[0060] A lower edge portion (lower horizontal edge portion) E2 of the periphery of the second belt insertion slot 24 extends horizontally between the left and right side edges of the periphery of the second belt insertion slot 24. Therefore, the tightening belt 8 inserted into the second belt insertion slot 24 comes into contact with the lower edge portion E2 of the periphery of the second belt insertion slot 24, and is bent downward.

[0061] 9, the tightening belt 8 extends from the rear side (back side) of the tightening adjustment tool 9 to the front side (front side) of the tightening adjustment tool 9 through the first belt insertion hole 23. At this time, the tightening belt 8 abuts against the upper side E1 of the middle frame part 22 and is bent, changing its extending direction from forward to downward. In other words, the upper side E1 of the middle frame part 22 serves as a direction changing part 25 that bends the tightening belt 8 and changes its extending direction downward.

[0062] Furthermore, the tightening belt 8 inserted through the first belt insertion hole 23 passes in front of the middle frame portion 22 and again extends from the front side (front side) of the tightening adjustment tool 9 to the rear side (back side) of the tightening adjustment tool 9 through the second belt insertion hole 24. At this time, the tightening belt 8 abuts against the lower side E2 of the periphery of the second belt insertion hole 24 and is bent, changing its extending direction from rearward to downward. In other words, the lower side E2 of the periphery of the second belt insertion hole 24 serves as a direction changing portion 25 that bends the tightening belt 8 and changes its extending direction downward.

[0063] As described above, the direction changer 25 includes the upper side E1 of the middle frame 22 and the lower side E2 of the periphery of the second belt insertion hole 24. In other words, the direction changer 25 has the upper side E1 as an upper oblique side extending in a direction that intersects obliquely with the extension direction of the tightening belt 8, and the lower side E2 as a lower horizontal side extending in a direction that intersects with the extension direction of the tightening belt 8 at a right angle.

[0064] As shown in Figures 9 to 11, the lower edge (lower horizontal edge) E2 of the periphery of the second belt insertion slot 24 has anti-slip portions 27. The anti-slip portions 27 are small tooth-like protrusions, and a plurality of them are arranged in a row along the lower edge E2. The anti-slip portions 27 catch on the band surface of the tightening belt 8, thereby preventing the tightening belt 8 from moving in the extension direction.

[0065] 10, when the tightening adjuster 9 is in the basic position with the distal end frame 26 facing downward, the anti-slip portion 27 presses against and engages with the band surface of the tightening belt 8 inserted through the second belt insertion hole 24. This causes the tightening belt 8 to enter a tensioned state where 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 anti-slip portion 27 in addition to contact resistance with the middle frame 22.

[0066] Therefore, in this state, if the tightening belt 8 is pulled downward (toward the tip) as described above, the tightening belt 8 is held by the anti-slip portion 27 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 first wearing portion 4A 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 first wearing portion 4A in a state in which it is firmly tightened around the waist of the user P. This allows the first main body portion 2A to be fixed to the user P more stably.

[0067] On the other hand, as shown in FIG. 11 , when the tightening adjuster 9 is in the release position with the distal end frame 26 pulled forward, the anti-slip portion 27 moves away from the band surface of the tightening belt 8. As a result, the tightening belt 8 enters a relaxed state in which movement in the extension direction is permitted, and the tightening state of the first attachment part 4A on the user P is released. At this time, the tightening belt 8 is permitted to move in the extension direction without interfering with the side edges or lower end of the shoulder strap part 3. Therefore, the side end part 12E of the horizontal strap part 12 (waist belt 7) moves away smoothly from the shoulder strap part 3. This allows the user P to easily remove the massage machine 1.

[0068] As described above, when the distal end frame 26 of the fastening adjuster 9 is oriented downward, it is in a tensioned state that prevents movement of the fastening belt 8 in the extension direction (see FIG. 10). Conversely, when the distal end frame 26 is oriented forward and raised, the fastening adjuster 9 is in a relaxed state that allows movement of the fastening belt 8 in the extension direction (see FIG. 11). In other words, the fastening adjuster 9 is provided on the shoulder part 3 as the first fastening adjuster of the first wearing part 4A, and allows tension and relaxation of the fastening belt 8 in the extension direction.

[0069] As shown in Figures 1 to 4, the second mounting part 4B is connected to the first mounting part 4A via a connecting belt 4C. The second mounting part 4B has a waist belt 31 and a belt fastener 32. As shown in Figures 5 to 7, the second mounting part 4B fixes the second main body part 2B to the user P with the waist belt 31 wrapped around the waist of the user P and the second treatment part 2T (see Figures 1 and 2) in contact with the second treatment part.

[0070] The second attachment part 4B is a belt member that can be wrapped around the entire waist of the user P. More specifically, when the massage machine 1 is attached to the user P, the second attachment part 4B extends from the second main body part 2B, passing through the left and right flanks of the user P, to the front of the abdomen. Then, by connecting the belt fasteners 32 in this state, the second attachment part 4B is fastened tightly to the waist of the user P. As a result, the lower part of the massage machine 1, including the second main body part 2B, is held around the waist of the user P.

[0071] As shown in FIGS. 1 to 4, the waist belt 31 is a band plate extending in the left-right direction of the second main body portion 2B, and has a right band portion 33 and a left band portion 34. The right band portion 33 is formed to extend to the right of the second main body portion 2B. On the other hand, the left band portion 34 is formed to extend to the left of the second main body portion 2B. In other words, the second main body portion 2B is provided in the center between the left and right of the waist belt 31. The waist belt 31 is formed integrally with the second main body portion 2B.

[0072] The right belt portion 33 and the left belt portion 34 are bendable. The waist belt 31 is formed into a loop by bending the right belt portion 33 and the left belt portion 34 forward of the second main body portion 2B. When the massage machine 1 is worn by the user P, the end of the right belt portion 33 is bent to the end of the left belt portion 34. The right and left belt portions 33, 34 are arranged so as to overlap each other from the front. The belt fastener 32 connects the ends of the right and left belt portions 33, 34 together. In other words, the right belt portion 33 is connected to the front of the left belt portion 34 by the belt fastener 32 while overlapping it.

[0073] 1, 2, 5, and 7, the waist belt 31 has an operating part C1. The operating part C1 is provided on the front belt part (in this embodiment, the right belt part 33) when the right belt part 33 and the left belt part 34 are overlapped and connected as described above.

[0074] The operating unit C1 is connected to the first massage mechanism 5A and the second massage mechanism 5B via a control circuit. The user P operates the first massage mechanism 5A and the second massage mechanism 5B using the operating unit C1. The first massage mechanism 5A and the second massage mechanism 5B are driven by power supplied from batteries built into the first main body 2A, the second main body 2B, the shoulder strap 3, etc.

[0075] The operating unit C1 may be provided on either the left or right shoulder strap 3 or on both the left and right shoulder straps 3, or the shoulder straps 3 and the waist belt 31 may be provided with separate operating functions (for example, the shoulder straps 3 may be provided with an operating unit mainly related to the operation of the first massage mechanism 5A, and the waist belt 31 may be provided with an operating unit mainly related to the operation of the second massage mechanism 5B).

[0076] The first massage mechanism 5A and the second massage mechanism 5B may be configured to be driven by power supplied from an external power source through a power cable. The first massage mechanism 5A and the second massage mechanism 5B may be configured to operate in conjunction with each other by operating the operation unit C1 to simultaneously massage the first treatment area and the second treatment area, or may be configured to operate independently by operating the operation unit C1 to intensively massage either the first treatment area or the second treatment area.

[0077] 1 and 2, belt fastener 32 is provided at the front-to-back overlapping portions of the ends of right and left belt portions 33, 34. Belt fastener 32 of this embodiment is a hook-and-loop fastener, and connects the ends of right and left belt portions 33, 34 by overlapping a pair of connecting bodies (a hook surface portion and a loop surface portion) that make up the hook-and-loop fastener. In other words, belt fastener 32 detachably connects the ends of right and left belt portions 33, 34 at a front position of second main body portion 2B.

[0078] In this embodiment, the belt fastener 32 has a hook surface portion, which is the first connecting body, provided on the rear surface (back side) of the right band portion 33, and a loop surface portion, which is the second connecting body, provided on the front surface (front side) of the left band portion 34. Note that the belt fastener 32 may have a loop surface portion, which is the second connecting body, provided on the rear surface of the right band portion 33, and a hook surface portion, which is the first connecting body, provided on the front surface of the left band portion 34.

[0079] The first connecting body is provided at the end of the right belt portion 33 with a predetermined left-right width (length in the extension direction). Similarly, the second connecting body is provided at the end of the left belt portion 34 with a predetermined left-right width (length in the extension direction). Therefore, the waist belt 31 can arbitrarily adjust the degree of tightness of the second attachment portion 4B around the user P by varying the overlap width of the connecting bodies of the belt fasteners 32. That is, the belt fasteners 32 are provided at the left and right ends (ends of the right belt portion 33 and the left belt portion 34) of the waist belt 31 as second tightness adjustment units of the second attachment portion 4B, and detachably connect these ends to each other at any position. This allows the degree of pressure of the second treatment portion 2T against the user P's waist (second treatment area) to be arbitrarily adjusted.

[0080] The belt fastener 32 is not limited to a hook-and-loop fastener, as long as it can connect the right belt portion 33 and the left belt portion 34 of the waist belt 31 so that they do not easily separate from each other. 2 may be a snap button, where male and female snaps are pressed together to fit together, or a hook, where a hook is hooked onto an eye to fit together. Alternatively, the belt fastener 32 may be a buckle with a snap-fit ​​structure.

[0081] 1 to 4, the connecting belt 4C is a band that connects the first attachment part 4A and the second attachment part 4B together. Specifically, the upper end of the connecting belt 4C is connected to the lower end of the waist belt 7, and the lower end is connected to the upper edge of the hip belt 31. In other words, the connecting belt 4C extends downward from the lower end of the waist belt 7, and the second attachment part 4B is connected to the lower end of the connecting belt 4C.

[0082] The connecting belt 4C is flexible. In this embodiment, the connecting belt 4C is made of a low-stretch or non-stretch fabric so that the vertical distance (connection direction) between the waist belt 7 and the hip belt 31 can be maintained substantially constant when the device is worn. This allows the second wearing part 4B to be wrapped around the waist of the user P, thereby more effectively preventing the first main body part 2A from floating up when the first massage mechanism 5A is activated. The connecting belt 4C may also be made of a highly stretchable material that allows the hip belt 31 to move vertically relative to the waist belt 7 when the device is worn. In this case, even if the user P changes their posture during use, the vertical distance between the waist belt 7 and the hip belt 31 changes accordingly, making it difficult for the second main body part 2B to slip off the second treatment area.

[0083] 1, 3, and 6, the connecting belt 4C has a length adjustment part 35 that allows adjustment of the length of the connecting belt 4C in the vertical direction (the direction in which the connecting belt 4C is connected to the waist belt 7 and the hip belt 31). In this embodiment, the length adjustment part 35 is a slide fastener, and the vertical length of the connecting belt 4C can be varied by engaging or disengaging the slide fastener.

[0084] Specifically, the length adjustment portion 35 extends between the left and right side edges of the connecting belt 4C in the middle portion between the upper and lower portions of the connecting belt 4C. The length adjustment portion 35 is composed of a pair of fastener elements J1 arranged parallel to each other in the vertical direction. The fastener elements J1 extend in the horizontal direction along the front surface of the connecting belt 4C and are spaced apart in the vertical direction. Therefore, when the fastener elements J1 are engaged with each other, the middle portion of the connecting belt 4C in the vertical direction is bent and shortened accordingly. On the other hand, when the fastener elements J1 are separated from each other, the middle portion of the connecting belt 4C is stretched and lengthened accordingly.

[0085] Note that the length adjustment part 35 is not limited to a slide fastener as long as it can adjust the vertical length of the connecting belt 4C. For example, the length adjustment part 35 may be a snap button that folds back and secures the upper or lower end of the connecting belt 4C, or that bends and secures the middle part as described above, or it may be an adjustment belt that is connected to the front or rear surface of the connecting belt 4C and adjusts the length in the vertical direction or changes the connecting position to secure the connecting belt 4C in a bent state.

[0086] <Modification> In the above embodiment, the fastening adjuster 9 is provided at the distal end 3E of the shoulder strap 3, but it may be provided between the proximal end 3F and the distal end 3E (midway) of the shoulder strap 3. More specifically, the loop 15 is provided between the proximal end 3F and the distal end 3E of the shoulder strap 3. The fastening adjuster 9 is connected to and held by the loop 15.

[0087] In this modification, the upper side E1 of the middle frame 22 may extend substantially horizontally between the left and right side edges of the periphery of the first belt insertion hole 23. In other words, the direction changer 25 has the upper side E1 as an upper horizontal side extending in a direction perpendicular to the extending direction of the tightening belt 8. and a lower side portion E2 as a lower horizontal side portion extending in a direction intersecting at right angles with the direction in which the tightening belt 8 extends.

[0088] In this device, the tightening belt 8, which extends forward from the side end 12E of the waist belt 7 (horizontal band portion 12), changes its extending direction upward before reaching the tightening adjustment tool 9, and is then inserted into the first belt insertion hole 23. At this time, the tightening belt 8 abuts against the upper side portion (upper horizontal side portion) E1 of the middle frame portion 22 and is bent, changing its extending direction from upward to forward.

[0089] Furthermore, the tightening belt 8 extending in front of the first belt insertion slot 23 is folded downward in a U-shape, passes in front of the middle frame portion 22, and is inserted from the front into the second belt insertion slot 24. At this time, the tightening belt 8 abuts against the lower side portion (lower horizontal side portion) E2 of the periphery of the second belt insertion slot 24 and is bent, and its extending direction is changed from rearward to downward. In this way, the extending direction of the tightening belt 8 is changed from upward to downward by the tightening adjustment tool 9.

[0090] As in the above embodiment, the anti-slip portion 27 is provided on the lower edge (lower horizontal edge) E2 of the periphery of the second belt insertion hole 24, and by catching on the belt surface portion of the tightening belt 8 extending downward from the second belt insertion hole 24, it prevents the tightening belt 8 from moving in the extension direction.

[0091] 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 lines in Figures 5 and 7, the first attachment part 4A may also be provided with a chest belt 60 in addition to the waist belt 7, tightening belt 8, and tightening adjustment device 9.

[0092] The chest belt 60 has a belt body 61 and a buckle 62. The belt body 61 is a flexible band made of nylon or the like, similar to the tightening belt 8, and extends forward from each of the left and right side end portions 12E of the horizontal belt portion 12. Therefore, when the massage machine 1 is worn by the user P, the belt body 61 passes under the left and right armpits of the user P and reaches the chest side.

[0093] The buckle 62 is provided at the tip of the belt body 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 bodies (e.g., a hook and a hook receiving portion) and can connect the two connecting bodies together using the elasticity of at least one of the connecting bodies (e.g., the hook). Therefore, the tips of the left and right belt bodies 61 can be easily separated and connected together using the buckle 62.

[0094] In this way, the massage machine 1 of this modified example 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 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, making it even easier to use.

[0095] 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.

[0096] In the above embodiment, the waist belt 7 is connected to the first main body portion 2A by sewing the upper end of the vertical belt portion 11 to the first main body portion 2A, but it may also be removably connected to the first main body portion 2A.

[0097] Specifically, the upper end of the vertical band 11 of the waist belt 7 is connected to the first main body portion 2A by a connecting member such as a slide fastener or snap buttons. Preferably, the waist belt 7 is connected to the first main body portion 2A by a slide fastener so that it does not easily come off when pulled downward. The handle portion 14 is formed by bending the tip of the tightening belt 8 into a loop. Therefore, the tightening belt 8 can be removed from the tightness adjustment tool 9 by pulling it in the extension direction opposite the tip. In this way, the waist belt 7 can be separated from the first main body portion 2A and the shoulder portion 3 by releasing the engagement of the slide fastener and removing the tip of the tightening belt 8 from the tightness adjustment tool 9. This allows the user P to change their style of use by removing the waist belt 7 from the first main body portion 2A and the shoulder portion 3, thereby improving versatility.

[0098] The first attachment part 4A may include a pad member that is placed between the first attachment part 4A and the body of the user P. In detail, for example, the pad member has a soft cover body and a cushioning material (a shock-absorbing material) that is housed inside the cover body, and is attached between the side end part 12E of the waist belt 7 of the tightening belt 8 and the tightening adjustment tool 9. In this case, the tightening belt 8 does not come into direct contact with the body of the user P, improving comfort.

[0099] As described above, the massage machine 1 of this embodiment is a massage machine comprising a first main body portion 2A equipped with a first massage mechanism 5A that massages a first treatment area including the shoulders of the user P, and a pair of shoulder strap portions 3 extending on the left and right sides of the first main body portion 2A. The massage machine is also provided with a first attachment portion 4A that is passed under the armpits of the user P to secure the first main body portion 2A to the user P while the first main body portion 2A is in contact with the first treatment area, a second main body portion 2B equipped with a second massage mechanism 5B that massages a second treatment area including the waist of the user P, a second attachment portion 4B that is wrapped around the waist of the user P to secure the second main body portion 2B to the user P while the second main body portion 2B is in contact with the second treatment area, and a connecting belt 4C that connects the first attachment portion 4A and the second attachment portion 4B.

[0100] According to this massage machine 1, the first main body 2A can be worn on the user P's back using the first attachment part 4A, and the second main body 2B can be wrapped around the user's waist using the second attachment part 4B connected to the first attachment part 4A, so that the user P can simultaneously massage the first treatment area (neck, shoulders) and the second treatment area (waist) in a hands-free state. In other words, the user P can keep both hands free even while simultaneously massaging the first treatment area and the second treatment area. This makes it possible to realize a massage machine 1 that is easy to use.

[0101] Furthermore, with this device, the shoulder strap 3 and the first attachment part 4A form a loop-shaped armhole at the bottom of the first main body part 2A, and the user P can put their arms through the armhole and secure the first main body part 2A to the user P as if they were carrying it on their back, so there is no problem with the first main body part 2A floating up from the first treatment area when the first massage mechanism 5A is driven. Moreover, because the first attachment part 4A is connected to the second attachment part 4B by the connecting belt 4C, wrapping the second attachment part 4B around the waist of the user P can more effectively prevent the first main body part 2A from floating up.

[0102] The first attachment portion 4A has a waist belt 7 extending rearward and downward from the first main body portion 2A, a tightening belt 8 extending from the waist belt 7 to the shoulder portion 3 and pulling in the extending direction to draw the waist belt 7 toward the shoulder portion 3, and a first tightening adjustment portion 9 provided on the shoulder portion 3 and allowing the tightening belt 8 to be tensioned and relaxed in the extending direction.

[0103] According to this massage machine 1, when the tightening belt 8 is pulled, the waist belt 7 is pulled in conjunction with the tightening belt 8. is pulled toward the shoulder strap portion 3, and the tightening belt 8 can be held in a tight state at that position, so that the first main body portion 2A can be quickly and easily attached and fixed to the user P. 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.

[0104] Moreover, with this massager, when the tightening belt 8 is pulled and the waist belt 7 is drawn toward the shoulder strap 3, the first main body portion 2A is pressed firmly against the first treatment area. In other words, the user P can simultaneously pull the tightening belt 8 to attach and fix the first main body portion 2A to the user P and press the first main body portion 2A against the first treatment area. This makes it possible to realize a massager 1 that is even easier to use.

[0105] Furthermore, with this device, the degree of pressure of the first main body portion 2A against the first treatment area 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.

[0106] The waist belt 7 extends rearward and downward from the upper portion of the first main body portion 2A.

[0107] According to this massage machine 1, the force exerted when the waist belt 7 is pulled toward the shoulder strap 3 is applied downward to the upper part of the first main body 2A, so that the first main body 2A can be more stably attached to the user P. This further improves usability.

[0108] The connecting belt 4C extends downward from the lower end of the waist belt 7, and the second attachment part 4B is connected to the lower end of the connecting belt 4C.

[0109] According to this massage machine 1, when the first massage mechanism 5A is driven, a reaction force of a directional component of the force that lifts the first main body portion 2A off the first treatment area is applied downward from the second attachment portion 4B via the connecting belt 4C and the waist belt 7 to the upper part of the first main body portion 2A, so that the first main body portion 2A can be pressed more appropriately against the first treatment area, thereby further improving usability.

[0110] The connecting belt 4C has a length adjusting portion 35 for adjusting the length of the connecting belt 4C in the connecting direction relative to the first attachment portion 4A and the second attachment portion 4B.

[0111] According to this massage machine 1, the length of the connecting belt 4C, i.e., the distance between the first main body portion 2A and the second main body portion 2B, can be adjusted according to the physique of the user P, so that the second main body portion 2B can be pressed more appropriately against the second treatment area, thereby further improving usability.

[0112] The second attachment portion 4B has a waist belt 31 extending from the rear of the second main body portion 2B to the left and right sides, and second tightening adjustment portions 32 provided at the left and right ends of the waist belt 31 and removably connecting the ends to each other at any position.

[0113] According to this massage machine 1, the degree of pressure of the second main body portion 2B against the second treatment area can be adjusted by adjusting the connection position of the ends of the waist belt 31. In other words, the strength of the massage can be adjusted by changing the degree of fastening of the waist belt 31. This further improves usability.

[0114] The first massage mechanism 5A is configured to generate a force having a directional component that lifts the first main body portion 2A from the shoulder when driven, and the first attachment portion 4A is configured to pass under the armpit. This prevents the first main body portion 2A from floating up.

[0115] According to this massage machine 1, the first main body portion 2A can be prevented from floating up during massage, so that the massage machine 1 can be made easier to use.

[0116] In the above embodiment, the first attachment part 4A is configured to be passed under the armpit of the user P, thereby fixing the first main body part 2A to the user P with the first main body part 2A in contact with the shoulder (first treatment part), but as shown in Fig. 12, the first attachment part 4A may have a shoulder belt 71, and may be configured to fix the first main body part 2A to the user P with the first main body part 2A in contact with the shoulder (first treatment part) by connecting the shoulder belt 71 to the second attachment part 4B. A so-called suspender structure may also be used.

[0117] 12, the massage machine 1 includes a first main body 2A, a second main body 2B, a shoulder strap 3, a first attachment 4A, and a second attachment 4B. The first attachment 4A includes a main body connecting belt 70 and a shoulder strap 71. The main body connecting belt 70 is a band extending rearward and downward from the upper portion of the first main body 2A, and is connected to the second main body 2B via a connecting belt 4C. In other words, the main body connecting belt 70 connects the first main body 2A and the second main body 2B.

[0118] The shoulder belt 71 has a belt body 72, a buckle 73, and a connecting position adjustment part 74. The belt body 72 is a bendable band made of nylon or the like, and extends downward from the lower end of the shoulder strap part 3. The belt body 72 is provided at the lower end of each of the left and right shoulder strap parts 3. Therefore, when the massage machine 1 is worn by the user P, the belt body 72 extends from the left and right shoulder strap parts 3, passes over the front of the user P's chest, and reaches the front of the waist belt 31.

[0119] The buckle 73 is a fastener that can be freely connected and separated using a snap-fit ​​structure, with a first connecting member connected to the tip of the belt main body 72 and a second connecting member connected to a support belt 75 provided at the front (right belt portion 33, left belt portion 34) of the waist belt 31. Therefore, the belt main body 72 can be easily connected and separated to the waist belt 31 using the buckle 73.

[0120] The connection position adjustment part 74 in this embodiment is configured with a belt length adjustment tool that can adjust the length of the support belt 75, and the connection position of the shoulder belt 71 with respect to the second attachment part 4B can be adjusted by changing the length of the support belt 75. Note that the connection position adjustment part 74 may be configured with a plurality of snap buttons that engage male and female snaps by pressing them together, or may be configured with a hook-and-loop fastener, as long as the belt main body 72 is configured so that it does not easily separate from the waist belt 31.

[0121] In this way, the massage machine 1 of this modified example is a massage machine comprising a first main body portion 2A equipped with a first massage mechanism 5A that massages a first treatment area including the shoulders of the user P, and a pair of shoulder strap portions 3 extending on the left and right sides of the first main body portion 2A, and is also provided with a first attachment portion 4A that secures the first main body portion 2A to the user P when the first main body portion 2A is placed against the first treatment area, a second main body portion 2B equipped with a second massage mechanism 5B that massages a second treatment area including the waist of the user P, and a second attachment portion 4B that is wrapped around the waist of the user P to secure the second main body portion 2B to the user P when the second main body portion 2B is placed against the second treatment area, and the first attachment portion 4A has a main body connecting belt 70 that connects the first main body portion 2A and the second main body portion 2B, and a shoulder strap 71 that extends from the shoulder strap portion 3 and is detachably connected to the second attachment portion 4B.

[0122] According to this massage machine 1, the first main body part 2A can be carried on the user's back using the first attachment part 4A, and the second main body part 2B can be attached and fixed to the user P by wrapping it around the waist using the second attachment part 4B connected to the first attachment part 4A, so that a massage machine 1 that is easy to use can be realized, similar to the massage machine 1 of the above embodiment.

[0123] Furthermore, the shoulder belt 71 has a connection position adjustment part 74 that adjusts the connection position of the shoulder belt 71 relative to the second attachment part 4B. This allows the connection position of the shoulder belt 71 relative to the second attachment part 4B to be adjusted, so that the massage machine 1 can be worn appropriately according to the physique of the user P. This more effectively prevents the first main body part 2A from floating up.

[0124] In addition to the above-described embodiments, the following embodiments can be considered. As described above, the first attachment portion 4A has shoulder straps 71 on both the left and right sides. Belt bodies 72 (left belt body, right belt body) extend from each of these shoulder straps 71. The left and right belt bodies are, for example, wide rubber bands that are stretchy and flexible. Attached to the ends of the extended left and right belt bodies are engaging members (for example, side release buckles) that connect the ends together. With this configuration, the first main body portion 2A can be securely fastened to the user P by passing the left belt body under the left armpit and the right belt body under the right armpit and engaging the engaging members at approximately the center of the user P's back.

[0125] In addition, a pair of connection position adjustment parts 74 consisting of buckles 73 are provided on the left and right sides of the lower part of the main body connection belt 70 (i.e., a pair on the left and right sides on the back side of the user P), and the left belt body that has passed under the left armpit is engaged with the left side connection position adjustment part 74, and the right belt body that has passed under the right armpit is engaged with the right side connection position adjustment part 74, so that the first main body part 2A can be fixed to the user P by the belt main body 72 that passes under both armpits.

[0126] The connection position adjustment portion 74 may be configured with a plurality of snap buttons that press male and female snaps together to fit them together, or may be configured with a hook-and-loop fastener, as long as the belt main body 72 is configured so that it is not easily separated from the main body connecting belt 70.

[0127] Even when such a structure is adopted, the first main body part 2A can be carried on the user P's back using the first attachment part 4A, and the second main body part 2B can be attached and fixed to the user P by wrapping it around the waist using the second attachment part 4B connected to the first attachment part 4A, so that a massage machine 1 that is easy to use can be realized, similar to the massage machine 1 of the embodiment described above.

[0128] Although the present invention has been described above, the embodiments disclosed herein should be considered to be illustrative and not restrictive in all respects. The scope of the present invention is defined by the claims, not by the above description, and is intended to include all modifications within the meaning and scope of the claims.
