Description

[Technical field]

[0001] The present invention relates to a percussion massage machine that performs a percussion massage on the treatment area of ​​a user, and more particularly to an attachment (accessory device) for a percussion massage machine that enables the amplitude and moving direction of the impactor of the percussion massage machine to be changed. [Background technology]

[0002] Massage machines suitable for performing a hitting massage on a treatment area, particularly handheld massage machines that are held by a user and strike the treatment area, are already available on the market.

[0003] This type of massage machine is usually equipped with a striker (hitting massage member) that extends and retracts from the tip or side of the handle. Furthermore, the main body contains a drive motor that drives the striker, and a retraction conversion mechanism that converts the rotational motion of the output shaft of the drive motor into the retraction motion of the striker (see Patent Document 1 and Non-Patent Document 1). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2002-282322 A [Non-patent literature]

[0005] [Non-Patent Document 1] Exagun Hyper (REG-04BK), manufactured by Dream Factory Co., Ltd., https: / / www.dr-air.com / jp / ja / products / exagun-hyper / Summary of the Invention [Problem to be solved by the invention]

[0006] The above-mentioned conventional massage machine (percussion massage machine) is capable of providing a comfortable tapping massage to stiff affected areas, fatigued areas, etc. However, if the user is thin and has little muscle mass, the impact vibration may resonate with the user's bones and internal organs, resulting in a massage that is too strong.

[0007] To meet this demand, it may be possible to develop a massage machine with a smaller amplitude of the striker's thrust, but on the other hand, a striker massage machine with a small amplitude of thrust would be unsatisfactory for users who have stiff areas to be treated and require a stronger stimulation.

[0008] Furthermore, although a percussion massage machine has a mechanism for applying percussion vibrations to the treatment area by a percussion element, users have various needs for massage machines, and some users may wish for a "massage that feels like grabbing and releasing" with this percussion massage machine. The massage machines disclosed in the prior art documents are unable to meet the above-mentioned needs.

[0009] In order to meet these various demands, it is conceivable to attach an attachment (accessory device) to the impact massage machine that changes the amplitude of the striker's protruding and retracting motion or changes the direction in which the striker protrudes and retracts.

[0010] In view of the above circumstances, the present invention aims to provide an attachment (an attachment for a percussion massage machine) that can change the amplitude of protrusion and retraction of the striker or change the direction in which the striker protrudes and retracts by placing a cap-like covering over the part of the striker that protrudes and retracts.

[0025] Hereinafter, an embodiment of a massage machine according to the present invention will be described with reference to the drawings, taking an impact type massage machine 1 as an example.

[0026] In the description of this embodiment, the front-rear direction, left-right direction, and up-down direction shown in the drawings will be used. Also, in order to make the drawings easier to understand, some of the components are omitted.

[0027] As shown in Figures 1 and 2, the impact type massage machine 1 of this embodiment (hereinafter, sometimes simply referred to as massage machine main body 1) has a handheld portion 3 formed in a rod shape with a circular cross section and sized so that a user can hold it with one hand, and a head portion 4 provided so as to protrude horizontally forward from the middle of the handheld portion 3. The head portion 4 is also formed in a rod shape with a circular cross section and has approximately the same diameter as the handheld portion 3. The head portion 4 is provided at a position approximately 1 / 3 of the way down from the upper end of the handheld portion 3, and the handheld portion 3 and the head portion 4 are arranged approximately perpendicular to each other.

[0028] A reciprocating body 9 is provided at the tip of the head portion 4 for transmitting reciprocating motion for performing a tapping massage, and a first treatment element 5, which is a tapping massage member, is attached to this reciprocating body 9.

[0029] The first treatment element 5 moves forward and backward with an amplitude of approximately 1 cm, and performs a percussion massage on the treatment area of ​​the user. The hand-held portion 3 is a hollow cylindrical member 26, and is provided therein with a drive motor 6 that serves as a drive source for the forward and backward movement of the first treatment element 5, a power source 7 for the drive motor 6, and an forward and backward conversion mechanism 8 (conversion mechanism) that converts the rotational motion from the output shaft of the drive motor 6 into the forward and backward movement of the first treatment element 5. Various configurations of the forward and backward conversion mechanism 8 can be adopted. One example will be described at the end of this embodiment.

[0030] As explained in [Problems to be Solved by the Invention], the above-mentioned impact massage machine 1 can provide a comfortable tapping massage to stiff affected areas or fatigued areas. However, if the user is thin and has little muscle mass, the impact vibrations may resonate with the user's bones and internal organs, resulting in a massage that is too strong. In addition, the impact massage machine 1 has a first treatment element 5 that applies impact vibrations to the treatment area, which moves back and forth from the main body 1 side, but users have various requests for massage machines, and some users may want a "massage that feels like grabbing and releasing" even with this impact massage machine 1.

[0031] Therefore, the applicant has developed an attachment 10 for reducing the amplitude of the first treatment element 5 (or the reciprocating body 9) or for changing the direction of the massage by the first treatment element 5 (or the reciprocating body 9). The attachment 10 for reducing the amplitude of the first treatment element 5 will be described in the first embodiment, and the attachment 10 for changing the moving direction of the first treatment element 5 will be described in the second embodiment. [First embodiment] 1 to 4 show an attachment 10 according to a first embodiment.

[0032] The attachment 10 is a cube with a vertical length of about 5 cm, a horizontal width of about 5 cm, and a front-to-back thickness of 4 cm, with chamfered corners. A second treatment head 11 of approximately the same diameter as the first treatment head 5 is provided on the front wall slightly above, and this second treatment head 11 can freely move forward and backward from the front wall of the attachment 10. A hole 12 is formed on the rear wall of the attachment 10 slightly below, into which the first treatment head 5 and the tip of the head 4 can be inserted, and by inserting the tip of the head 4 into this hole 12, the attachment 10 is fixed to the tip of the head 4 as shown in FIG. 2.

[0033] 3 and 4, an amplitude conversion mechanism 13 for changing the amplitude of the first treatment element 5 is built into the attachment 10. The amplitude conversion mechanism 13 has a lever member 14 and a biasing member 15 for generating a biasing force for pushing the lever member 14 back toward the tip of the head portion 4 (in other words, toward the first treatment element 5).

[0034] The lever member 14 is a plate-like member that is narrow at the top and wide at the bottom, flaring outward. The upper end of the lever member 14 is rotatable (swingable) in the front-rear direction (the direction in which the first treatment head 5 advances and retreats) around a shaft that faces the left-right direction by a lever pivot shaft 28. Both ends of the lever pivot shaft 28 are attached to a case body 20 that forms the outer shell of the attachment 10. The lever member 14 has a width from the center to the lower end in the vertical direction that is slightly wider than the diameter of the first treatment head 5, and the inside is thin and concave, consisting of an edge and a front wall (not shown). The reason for the concave interior will be described later. A rod-shaped member 17 is hung across the lower end of the lever member 14 so as to penetrate in the left-right direction, and the top of the first treatment head 5 is disposed so as to contact the rod-shaped member 17 from the rear side (one side in the rotation direction).

[0035] A helical spring is wound around the lever pivot shaft 28A that supports the upper end of the lever member 14. This helical spring is the aforementioned biasing member 15. The lever member 14 is biased backward by this helical spring, so that the rod-shaped member 17 is always in contact with the tip of the first treatment head 5.

[0036] On the other hand, a hemispherical protrusion 16 protruding backward is formed at the rear of the second treatment element 11, and this hemispherical protrusion 16 is adapted to contact the front wall surface (front side, in other words, the other side in the rotation direction) of the lever member 14 at approximately 1 / 2 the vertical direction. In other words, when viewed from the axis of the lever rotation shaft 28A, the distance SB to the part where the first treatment element 5 contacts is approximately twice the distance SF to the part where the second treatment element 11 contacts.

[0037] FIG. 4 shows how the amplitude of the first treatment element 5 is changed by the amplitude changing mechanism 13 of the attachment 10. As shown in FIG.

[0038] First, by turning on the switch on the handheld portion 3 of the massage machine main body 1, the first treatment element 5 starts to move forward and backward with an amplitude of about 1 cm.

[0039] As shown in Fig. 4(a), when the attachment 10 of the first embodiment is attached to the tip of the head portion 4, when the first treatment element 5 advances, as shown in Fig. 4(b), the lower end of the lever member 14, i.e., the rod-shaped member 17, moves to push out, and the lever member 14 is pushed forward around the lever pivot shaft 28A. At that time, the lever member 14 moves like a seesaw, and at a point (SF) where the rotation radius is about half from the axis of the lever pivot shaft 28A, the first treatment element 5 is pushed forward by about half the moving distance. In other words, the lever member 14 pushes out the second treatment element 11 by about half (about half the amplitude of the first treatment element 5) via the hemispherical member, and the amplitude of the second treatment element 11 decreases.

[0040] As described above, the rear side of the lever member 14 is concave and only the edge portion exists (not shown). Therefore, when the first treatment element 5 advances and pushes the rod-shaped element 17 as shown in Fig. 4(b), the existence of the concave shape can reliably prevent the rear wall surface of the lever member 14 from interfering with the first treatment element 5. As a result, the amplitude conversion mechanism 13 can operate smoothly.

[0041] Thereafter, as shown in Figure 4(a), when the first treatment head 5 retracts, the lever member 14 rotates around the lever pivot axis 28 so as to be pushed back by the biasing member 15, and contact between the rod-shaped member 17 and the first treatment head 5 is maintained.

[0042] As the first treatment element 5 of the massage machine main body 1 moves back and forth, the situations of Fig. 4(a) and Fig. 4(b) are repeated, and the amplitude of the second treatment element 11 becomes smaller than that of the first treatment element 5, and the amplitude is reduced. In this way, by attaching and detaching the attachment 10 (accessory device), the amplitude of the first treatment element 5 can be easily changed (reduced), and it is possible to provide a percussion type massage machine 1 that can reliably meet the needs of various users. To further reduce the amplitude of the second treatment element 11, it is preferable to change the position where the second treatment element 11 and the lever member 14 come into contact with each other to a position closer to the lever rotation axis 28, so that the rotation radius is shortened (distance SB>distance SF). [Second embodiment] Next, a second embodiment of the attachment 10 (accessory) according to the present invention will be described below.

[0043] The attachment 10 of the second embodiment is also attached to the massage machine main body 1 in which the first treatment element 5 that applies impact vibration to the treatment part reciprocates back and forth. However, users have various requests for massage machines, and in some cases, users may want a "massage that feels like grabbing and releasing" with the impact type massage machine 1.

[0044] Therefore, by attaching the attachment 10 of the second embodiment to the massage machine body 1, it becomes possible to change the moving direction of the first treatment element 5. That is, the attachment 10 of the second embodiment changes the striking motion of the first treatment element 5 in the forward and backward directions into a gripping motion (movement in the left-right and up-down directions) by the gripping treatment element 21 (second treatment element 11), and a direction changing mechanism 25 is provided within the attachment 10.

[0045] 5 and 6 show an attachment 10 according to a second embodiment.

[0046] The case body 20, which is the outer shell of this attachment 10, is trefoil-shaped when viewed from the front, and the rear is circular with an area approximately half that of the front, with the outer shell shape tapering from the front side to the rear side.

[0047] Three gripping treatment elements 21 are provided protruding from the front surface of the case body 20. The gripping treatment elements 21 are arranged along the periphery of the attachment 10 at 120° intervals from each other, and are arranged so as to protrude forward from three holes 22 formed in the front surface. More specifically, a long arm member 23 protrudes through the holes 22 so as to face forward, and a gripping treatment element 21 (second treatment element) is attached to the tip of the arm member 23.

[0048] In addition, it is sufficient that a plurality of arm members 23 are provided, and four or five arm members 23 may be provided. In Fig. 5 and Fig. 6, the cover body covering the second treatment head 11 is omitted, but in reality, a cover body made of cloth or silicon may be provided so as to cover the entire second treatment head 21 and the arm members 23. Only the second treatment head may protrude from this cover body.

[0049] 5 and 6, the gripping treatment element 21 is substantially spherical and made of a material such as plastic or rubber that does not apply a load to the treatment part. The base end of the arm member 23 is connected to a direction changing mechanism 25 built into the attachment 10, and is a member that constitutes the direction changing mechanism 25. Due to the action of this direction changing mechanism 25, the tip end of the arm member 23, i.e., the three treatment elements, move toward and away from each other substantially along a plane (called a vertical plane) that includes straight lines extending in the up-down and left-right directions.

[0050] A hole 12 is formed on the rear surface of the case body 20 of the attachment 10 into which the first treatment head 5 and the tip of the head portion 4 on the massage machine main body 1 can be inserted, and by inserting the tip of the head portion 4 into this hole 12, the attachment 10 becomes fixed to the tip of the head portion 4 as shown in Figure 6.

[0051] As shown in FIGS. 7 and 8, the attachment 10 includes a direction changing mechanism 25 built therein, which changes the forward and backward movement of the first treatment element 5 into a movement of the treatment element 21 approaching and receding.

[0052] The direction changing mechanism 25 has a rod-shaped arm member 23, a cylindrical member 26 equipped with a circular bottom plate 27 (engagement member) with which the top of the first treatment head 5 comes into contact, and a biasing member 15 that constantly biases the cylindrical member 26 toward the first treatment head 5. Furthermore, it has a rod-shaped connecting lever member 30 that connects the arm member 23 and the cylindrical member 26.

[0053] Specifically, as shown in Figures 7 and 8, a cylindrical member 26 is provided so that the center of its bottom plate 27 is in contact with the top of the first treatment element 5 of the massage machine body 1. The opposite side of the bottom plate 27 of the cylindrical member 26 is open, and the cylindrical member 26 is a hollow member. The cross-sectional diameter of the cylindrical member 26 is approximately the same as or slightly smaller than the diameter of the first treatment element 5.

[0054] Three connecting lever members 30 are attached at intervals of 120° to the periphery of the bottom plate 27 of the cylindrical member 26. The connecting lever members 30 have a rod shape that is slightly shorter than the arm members 23, and their base ends are rotatably attached to the periphery of the bottom plate 27 of the cylindrical member 26. More specifically, the base ends of the connecting lever members 30 are rotatable around a tangent that contacts the periphery of the bottom plate 27 of the cylindrical member 26 (i.e., the circular engaging member).

[0055] A lever pivot shaft 28B having both ends fixed to the case body 20 constituting the outer shell of the attachment 10 is provided penetrating the middle part of the connecting lever member 30. Therefore, the connecting lever member 30 is also rotatable about the axis of this lever pivot shaft 28B. Meanwhile, an arm pivot shaft 29 having both ends fixed to the case body 20 constituting the outer shell of the attachment 10 is also provided penetrating the middle part of the arm member 23. Therefore, the arm member 23 is rotatable about the axis of the arm pivot shaft 29.

[0056] The base end of the arm member 23 is rotatably connected to the tip of the connecting lever member 30. The tip of the arm member 23 protrudes forward from a hole 22 formed in the case body 20 of the attachment 10, and a gripping treatment element 21 is provided at the tip.

[0057] The biasing member 15, which is made of a helical spring, is disposed inside the aforementioned cylindrical member 26. The rear end of the biasing member 15 contacts the bottom plate 27 of the cylindrical member 26, and the front end of the biasing member 15 protrudes from the open side of the cylindrical member 26 and contacts the inside of the front surface of the case body 20.

[0058] According to the direction changing mechanism 25 having the above-mentioned configuration, it is possible to convert the forward and backward movement of the first treatment element 5 into the gripping movement (up-down and left-right movement) of the gripping treatment element 21.

[0059] That is, when the first treatment head 5 advances forward from the state shown in FIG. 8(a), as shown in FIG. 8(b), it pushes the cylindrical member 26 forward via the bottom plate 27 of the cylindrical member 26. At this time, the helical spring, which is the biasing member 15, is compressed. When the bottom plate 27 is pushed forward, the base end of the connecting lever member 30 is also pushed forward, and the tip ends of the connecting lever member 30 move backward and away from each other around the axis of the lever rotation shaft 28B like a seesaw. Then, the base end side of the arm member 23, which is rotatably connected to the tip end of the connecting lever member 30, also moves backward and away from each other. Since the arm member 23 is also pivoted at its midpoint by the arm rotation shaft 29, it also operates like a seesaw, and the tip ends of the arm members 23 move slightly backward and close to each other. As a result, the three gripping treatment heads 21 move so as to gather in the center, i.e., inward, when viewed from the front.

[0060] Then, as shown in Fig. 8(b) to Fig. 8(a), the first treatment element 5 retracts into the head portion 4, and the cylindrical element 26 is pushed backward by the biasing element 15, and the base end of the connecting lever element 30 is pulled backward, so that the connecting lever element 30 rotates around the axis of the lever rotating shaft 28B, and the tip of the connecting lever element 30 approaches the central axis (the axis that faces the front-rear direction and passes through the center of the first treatment element 5). Then, the base end of the arm element 23 also approaches the center and rotates in a seesaw shape around the axis of the arm rotating shaft 29, and the gripping treatment element 21 at the tip of the arm element 23 moves away from the central axis. That is, the three gripping treatment elements 21 move away from each other when viewed from the front.

[0061] Even if there are multiple arm members 23 (for example, four or five), when the first treatment element 5 advances forward, the tips of all the arm members 23 move closer to each other inward. As a result, the multiple gripping treatment elements 21 move to gather at the center (the center of the case body 20) when viewed from the front.

[0062] In addition, the direction changing mechanism 25 may be structured such that the connecting lever member 30 is eliminated, the base end of the arm member 23 is engaged with the bottom plate 27, and the second treatment member 21 is provided at the tip of the arm member 23. Specifically, a long groove is formed in the disk-shaped bottom plate 27 facing the center direction, and the base end of the arm member 23 is structured to prevent it from slipping out of the long groove. Then, when the first treatment member 5 pushes the bottom plate 27 forward, the base end of the arm member 23 slides along the long groove and moves toward the center of the bottom plate 27 (the above-mentioned central axis), and as a result, the tip ends of the arm members 23 can be moved in directions away from each other outward.

[0063] In addition, the tip of the first treatment head 5 can be made to be engageable with the bottom plate 27 by a magnetic member or a hook member. When the bottom plate 27 is pulled backward in such an engaged state, the base end of the arm member 23 moves away from the center of the bottom plate 27 (the above-mentioned central axis), and as a result, the tip ends of the arm members 23 can be moved closer to each other.

[0064] As described above, the direction changing mechanism 25 built into the attachment 10 of the second embodiment makes it possible to change the "front-rear movement" of the first treatment element 5 into the "left-right and up-down movement" of the grasping treatment element 21, the second treatment element, in other words, into a "direction intersecting the direction of the first treatment element 5 moving in and out." If it is possible to easily change the movement of the treatment elements in this way, it becomes possible to reliably meet various requests from users, for example, a request for a "massage of grasping and releasing" even with the impact massage machine 1.

[0065] However, if the period of the advancement and withdrawal movement of the first treatment element 5 is fast for impact massage, the movement of the gripping treatment element 21 converted in the attachment 10 of the second embodiment becomes too fast, and it may be difficult to obtain the desired treatment effect (grasp massage by the gripping treatment element 21). It is preferable that the gripping movement by the three gripping treatment elements 21 is performed relatively slowly.

[0066] In order to meet such a demand, the following mechanism may be provided. That is, a small permanent magnet is embedded near the hole 12 provided in the attachment 10 of the second embodiment. Meanwhile, a magnetic sensor such as a Hall element is provided at the position of the head part 4 corresponding to the permanent magnet. When the magnetic sensor detects magnetism, it becomes clear that the attachment 10 attached to the head part 4 is the attachment 10 of the second embodiment and is equipped with a mechanism for performing treatment using the gripping treatment element 21. Therefore, by slowing down the rotation speed of the drive motor 6 of the massage machine main body 1, for example, and changing the amplitude and frequency of the first treatment element, it becomes possible to realize a comfortable movement of the gripping treatment element 21 and a gripping massage.

[0067] Specifically, the massage machine main body 1 has various operation modes and operation patterns. For example, in order to effectively relieve stiffness in the treatment area, there is an operation mode 1 in which "the first treatment element 5 (reciprocating body 9) is vibrated at low vibration and low amplitude for a certain period of time, then at high vibration and high amplitude, and finally at low vibration and low amplitude for cooling down." The user can select this operation mode 1 by selecting one of the automatic courses of the massage machine main body 1. At this time, when the magnetic sensor detects that the attachment 10 of the second embodiment has been attached, it is possible to switch to another operation mode and change to operation mode 2 in which "the first treatment element 5 (reciprocating body 9) is moved forward and backward with the same vibration frequency and the same amplitude from start to finish."

[0068] The attached sensor is not limited to a magnetic sensor, but may be a mechanical sensor. [Massage machine body] The above-mentioned two types of attachments 10 are attached to the impact massage machine 1. However, the structure and shape of the impact massage machine 1 to which the attachment is attached are not particularly limited. An example of the impact type massage machine 1, that is, the massage machine main body 1, is shown in FIG.

[0069] As shown in Fig. 9, the massage machine main body 1 suitable for the attachment 10 of the present invention has a handheld portion 3 sized to be held by a user in one hand, and a head portion 4 provided to protrude horizontally from the middle of the handheld portion 3. The handheld portion 3 and the head portion 4 are arranged to be substantially perpendicular to each other. A first treatment element 5 (first treatment element) is provided at the tip of the head portion 4.

[0070] The hand-held portion 3 is a hollow cylindrical member 26, and a drive motor 6 is provided inside and at the top thereof for generating a drive force for the forward and backward movement of the first treatment head 5. The shaft center of the drive motor 6 is provided so as to face downward.

[0071] On the other hand, the tip of a long rod-shaped crank arm 40 is rotatably connected to the first treatment head 5 by a crank pin, and the base end of the crank arm 40 is eccentrically attached to the rotating shaft of the drive motor 6 through an eccentric member. On the other hand, the first treatment head 5 is rotatably attached to the tip of the crank arm 40. Therefore, when the drive motor 6 is rotated, the rotating shaft rotates, and the base end of the crank arm 40 rotates eccentrically. Accordingly, a "piston-crank motion" is generated by the crank arm 40, and the first treatment head 5 corresponding to the piston reciprocates back and forth in a short period. In order to suppress unnecessary vibrations generated by this piston-crank motion, a counterweight is provided on the eccentric member on the opposite side to the eccentric position of the base end of the crank arm 40.

[0072] A power source 7 for driving the drive motor 6 is provided inside the lower part of the hand-held portion 3. This power source 7 is preferably a rechargeable battery.

[0073] The above-mentioned configuration of the massage machine main body 1 is an example, and is not limited in any way as long as the first treatment element is the first treatment element 5 that moves back and forth and the attachment 10 is attached to the first treatment element 5. In addition, the first treatment element is not limited to one that performs a striking type massage.

[0074] As described above, the embodiments disclosed herein should be considered to be illustrative and not restrictive in all respects. In particular, in the embodiments disclosed herein, matters not explicitly stated, such as operating conditions, operation conditions, dimensions and weights of components, do not deviate from the scope of ordinary practice of a person skilled in the art, and are matters that can be easily imagined by a person skilled in the art.
