  However, the conventional massage devices have the following problems.

  In the form (1), the fir tree 111, 112 can simultaneously apply the fir stimulation to both feet, but the roller stimulation cannot be performed.

  In the form (2), it is possible to simultaneously apply both the foot stimulation by the wheel rings 111 and 112 and the roller stimulation by the rollers 121 and 122, but the structure is complicated because the shafts 100 and 101 are arranged side by side. The device becomes larger.

  In the form (3), the rollers 121 and 122 can simultaneously apply roller stimulation to both feet. However, since only one pair of the ring wheels 111 is provided, it is not possible to simultaneously apply both sides to the foot stimulation.

  In the form (4), both the legs can be simultaneously stimulated by the wheel rings 111 and 112. However, since only one roller 121 is provided, the roller stimulation cannot be simultaneously applied to both legs.

  The present invention has been made paying attention to such problems, and provides a massager that can simultaneously apply scissoring and roller stimulation to both feet while realizing simplification and downsizing of the structure. It is an object.

In order to achieve the above object, a massager according to the present invention comprises a driving means for rotationally driving a shaft, and a pair of momi wheels attached non-parallel to the shaft, and the pair of momi wheels. the provided two pairs on the shaft, the support plate to which the also integrally attached to the saw wheels on the outside of the fir wheels of both outer sides, and the end plate mounted with a gap on the outside of the support plate, and the support plate The support plate and a plurality of sub-rollers for pressure stimulation provided so as to be able to rotate by the end plate and in a circumferential shape in a gap with the end plate .

  FIG. 14 schematically shows the configuration of this massage device. Two shafts 91 and 92 are provided on one shaft 90, and rotary rollers 95 and 96 for pressure stimulation are provided on the outside thereof. Yes. For this reason, it is possible to simultaneously give both feet a foot stimulation by two pairs of wheel rings or roller stimulation by two rotating rollers. In addition, since only one shaft is used, a compact massager can be realized with a simple structure as compared to the case where two shafts are arranged in parallel (FIG. 15B).

On the other hand, the rotating roller is provided on the outer side of the wheel, but if a wide roller is provided on the outer side of the wheel as shown in FIG. Therefore, the rotation roller is provided with a pressure stimulation sub-roller that can rotate in a gap between a support plate integrally attached to the outer side of the outer ring and the end plate attached to the outer side of the support plate. By adopting a configuration in which a plurality of circumferences are arranged, the width of the rotating roller is suppressed, the limited space can be used effectively, and the width of the massage device does not need to be increased.

  In addition, when a plurality of convex portions for pressing stimulation are provided between the pair of grinding wheels, and the sub-roller and the convex portion are formed so as to have a plurality of protruding degrees, respectively, during the grinding stimulation by the grinding wheel. A pressing stimulus can be given by the convex portion, and further, the pressing stimulus during the roller stimulus and the fir tree stimulus changes in strength, and various stimuli can be realized.

  In addition, a center wheel positioned axially on the rotationally driven shaft is provided between the inner wheel of the pair of wheel wheels, and between the center wheel and the inner wheel. If an elastic member that constantly urges each inner side wheel to the outside is provided and the distance between each pair of wheel is adjustable independently, the distance between each pair of wheel By providing a mechanism that adjusts the distance, the interval can be adjusted according to the thickness of each person's foot, and it is possible to give a fir stimulus with a constant strength regardless of whether the foot is thick or thin. In addition, since the distance between the pair of wheel rings can be adjusted independently, the pressure of the other foot is not affected by the thickness of one foot.

  Further, the rotating roller is simpler if a plurality of sub-rollers are set to have the same width in the axial direction in which the rotation is driven, and the plurality of sub-rollers are arranged in a single row in a circumferential shape. A small massage device can be realized with a simple structure.

  According to the present invention, two pairs of worm wheels are provided on one shaft, and the rotation roller is provided by effectively utilizing the space outside the outer rim wheels. It is possible to give a fir stimulus by a fir wheel or a roller stimulus by two rotating rollers. Moreover, it is possible to realize a small massage device having a simple structure using only one shaft and suppressing the width.

  Hereinafter, the present invention will be described in more detail with reference to embodiments.

  An external perspective view of the massage device according to the embodiment is shown in FIG. 1, and a perspective perspective view showing the internal structure is shown in FIG. The massage device includes a main body case 1, a massage mechanism 10 built in the main body case 1, and a cover 2 that covers the massage mechanism 10. The main body case 1 has an operation unit 3 for adjusting power ON / OFF, fir stimulation / roller stimulation intensity (rotational speed), a handle 4 for carrying the massager, and a footrest on which both feet are placed during massage. Part 5 is provided.

  Furthermore, the detail of the massage mechanism 10 is demonstrated with reference to FIGS. 3 is a plan view, FIG. 4 is a sectional view, FIGS. 5 and 6 are enlarged plan views, FIGS. 7 and 8 are enlarged sectional views, and FIGS. 9 to 13 are exploded perspective views.

  In the massage mechanism 10, a bearing 12 is attached to one end of one shaft 11, and a motor (driving means) 14 is connected to the other end via a gear case 16. The motor 14 and the gear case 16 are integrated and positioned by a C-ring 85 provided on the shaft 11 portion outside the gear case 16. The gear case 16 includes a bearing 17 that supports the other end of the shaft 11 and a gear 18 that is fixed to the shaft 11 and meshes with the rotating shaft of the motor 14. The shaft 11 is rotatably supported by bearings 12 and 17. Accordingly, the rotation of the motor 14 is transmitted to the shaft 11 via the gear 18, and the shaft 11 rotates while being supported by the bearings 12 and 17.

  A center wheel 20 is attached to a substantially central portion of the shaft 11, and the center wheel 20 is positioned by a C ring 80. A pair of mill wheels 22 and 23 are provided on both sides of the center wheel 20, respectively. Each pair of milling wheels 22 and 23 is non-parallel and attached to the shaft 11 opposite to each other. Here, the fir wheels 22 and 23 have a large number of convex portions 22a and 23a on the inner side.

  In the two pairs of mill wheels 22 and 23, the inner mill wheels 22 and 23 (both sides of the center wheel 20) have inner disks 25 and 26 as support plates for supporting the mill wheels from the back side, respectively. The wheel rings 22 and 23 and the disks 25 and 26 are integrally attached with screws 28 and 29, respectively, and can be displaced in the axial direction. Inner mill wheels 22 and 23 are fixed to the shaft 11 by a key 81 fitted in the key groove 11a of the shaft 11, rotate integrally with the shaft 11, and are spring pins inserted into the pin insertion holes 11b of the shaft 11. The movement outward in the axial direction is restricted by 82.

  Springs 32 and 33 are inserted into the shaft 11 portion between the center wheel 20 and the inner milling wheels 22 and 23. The inner ends of the springs 32 and 33 are engaged with the center wheel 20, and the outer ends are engaged with the ring wheels 22 and 23 through the disks 25 and 26. Thereby, the springs 32 and 33 always urge the inner side wheel rings 22 and 23 outward in the axial direction, respectively. However, in FIG. 7, the spring 33 is shown in a compressed state. By extending and contracting the springs 32 and 33, the inner milling wheels 22 and 23 are displaced in the axial direction, and the distance between the pair of milling wheels 22 and 23 can be adjusted.

  Roller bodies 35 and 36 are provided on the outer shaft 11 portions of the inner mill wheels 22 and 23, respectively. The roller bodies 35 and 36 have large and small rollers 35a, 35b, 36a and 36b, respectively, as convex portions for pressing stimulation. The large and small rollers 35a, 35b, 36a, 36b are located between each pair of mill wheels 22, 23.

  The outer wheel rings 22 and 23 located outside the roller bodies 35 and 36 are fixed to the shaft 11 by a key 83 fitted in the key groove 11 c of the shaft 11, and rotate integrally with the shaft 11. The outer side wheels 22, 23 also have outer disks 25, 26 as support plates for supporting the side wheels from the back side, like the inner side wheels. Further, end plates 41 and 42 are provided on the outer shaft 11 of the outer disks 25 and 26. The end plates 41 and 42 are also fixed to the shaft 11 with a key 83. The outer mill wheels 22 and 23, the outer disks 25 and 26, and the end plates 41 and 42 are integrally attached with screws 28 and 29, respectively, and rotate integrally with the shaft 11. Further, the end plates 41 and 42 are positioned by a C ring 84 provided on the outer shaft 11 portion.

  Between the outer disks 25, 26 and the corresponding end plates 41, 42, a plurality of large and small sub-rollers 44a, 44b, 45a, 45b that can rotate and a plurality of non-rotating rollers serve as rotating rollers for pressing stimulation. The protrusions 46 and 47 are arranged in a circumferential combination. Here, the sub rollers 44a, 44b, 45a, 45b and the projections 46, 47 are all set to have the same axial width. The protrusions 46 and 47 not only act as spacers that keep the distance between the disks 25 and 26 and the end plates 41 and 42 constant, but also protrude from the gap between the disks 25 and 26 and the end plates 41 and 42. Similar to the large and small sub-rollers 44a, 44b, 45a, 45b, it acts also for pressure stimulation.

  Further, each of the disks 25 and 26 has projections 25a and 26a that prevent the corresponding wheel rings 22 and 23 from riding on the outer periphery of the disks 25 and 26. In particular, at locations where the distance between the pair of milling wheels 22 and 23 is narrow, the grinding wheels 22 and 23 are susceptible to reaction from the treatment site (foot) even during the rotation operation, so the corresponding portions of the disks 25 and 26 A plurality of protrusions 25a and 26a are provided on the surface.

  On the other hand, in this massage mechanism 10, in order to prevent sound generation when each part slides during the rotation operation, parts that may slide with each other are made of different materials (for example, synthetic resin). Here, for example, as the main parts, the center wheel 20, the inner disks 25 and 26 on both sides thereof, and the inner wheel rings 22 and 23, and the outer wheel rings 22 and 23, the outer disks 25 and 26, For the three parts of the end plates 41 and 42, the adjacent parts are made of different resins. For example, POM (polyacetal resin), ABS (acrylonitrile butadiene styrene), and nylon resin are combined so that adjacent parts are not made of the same resin.

  In the massage device configured as described above, two pairs of wheel rings 22, 23 are provided on one shaft 11, and a rotary roller for pressing stimulation (large and small) is provided outside each pair of wheel rings 22, 23. Since the sub-rollers 44a, 44b, 45a, 45b and the projections 46, 47) are provided, it is possible to simultaneously apply fir stimulation or roller stimulation to both feet. In addition, since the rotating roller effectively uses the space outside the milling wheels 22 and 23 and the axial width of the rotating roller is narrow, two pairs of milling wheels 22, 23 and 2 are provided on one shaft 11. Even if two rotating rollers are provided, the entire massager does not have to be wide. Of course, since there is only one shaft 11, the structure can be simplified and downsizing is achieved.

  When performing massage with this massager, both feet (calves, thighs, etc.) are placed on the massage mechanism 10 covered with the cover 2 from the footrest portion 5. In the case of receiving the irritating stimulus by the pair of worm wheels 22 and 23, the treatment site is placed on both sides of the central portion of the cover 2, and the rollers by the rotating rollers (large and small sub-rollers 44a, 44b, 45a, 45b and protrusions 46, 47). When receiving a stimulus, place treatment sites on both ends of the cover 2.

  In the komi stimulation, the distance between each pair of kneading wheels 22 and 23 is changed to a large or small value by rotation, whereby a kneading massage is performed. At this time, since the roller bodies 35, 36 have large and small rollers 35a, 35b, 36a, 36b for pressing stimulation, not only the burning stimulation by the wheel rings 22 and 23 but also the pressing stimulation by these rollers is applied, Monotonicity is avoided and various fir tree stimuli are applied to the treatment site.

  On the other hand, in the roller stimulation, strong and weak pressure stimulation is given to the treatment site by the large and small sub-rollers 44a, 44b, 45a, 45b and the protrusions 46, 47 as rotating rollers. Here, since the rotating roller is composed of three types of parts, the pressing force also changes accordingly, and complicated roller stimulation is applied to the treatment site.

  On the other hand, when putting a foot between each pair of wheel rings 22, 23, the thickness of the left and right feet may be somewhat different in the person as well as others. Even in such a case, the inner milling wheels 22 and 23 can be displaced in the axial direction only by being urged outward by the springs 32 and 33. The distance between the wheel rings 22 and 23 is adjusted according to the thickness of the foot. In addition, since the inner milling wheels 22 and 23 can be displaced independently of each other, a problem that may occur when the inner milling wheels 22 and 23 can be displaced together is that when the spacing between one of the milling wheels is narrowed, the other spacing is widened. No matter what the thickness of one foot is, the pressure on the other foot is not affected.

  In addition, during the operation of the wheels 22 and 23, the wheels 22 and 23 try to ride on the outer circumferences of the corresponding disks 25 and 26 by the reaction force from the feet. Since the wheels 25a and 26a are provided, the fir wheels 22 and 23 do not run on the outer circumferences of the disks 25 and 26.

  In addition, the massage device of the said embodiment is an example, and various changes are possible. For example, the rotating roller is composed of three types of parts, large and small sub-rollers 44a, 44b, 45a, 45b and protrusions 46, 47, but the protrusions 46, 47 may not be used for pressure stimulation. Further, the sub-rollers and the protrusions are all set to have the same width in the axial direction, but the width in the axial direction may be gradually increased or decreased in the axial direction. Alternatively, the sub-rollers and the protrusions may have the same or different degree of protrusion from their circumference. That is, various types of roller stimulation can be realized by variously changing or combining the types of components of the rotating roller, the axial width and the degree of protrusion.
