Description

  The present invention applies a high-speed vibration to a user who uses both feet on a footrest to generate an appropriate exercise effect on the entire body as well as stimulation on the sole, resulting in shape-up, muscle The present invention relates to a vibration health device capable of exerting effective whole body effects such as reinforcement and fatigue recovery.

  Various types of equipment are provided for the foot massager that vibrates the footrest on which a foot is placed using a vibration device at a speed of about 0.5 to 3.0 mm and a speed of about 450 to 1700 rpm. ing. These sole massagers can stimulate fatigue and stimulate the functions of various organs by stimulating the soles dotted with many points because peripheral nerves and arterial capillaries concentrate. Widely used because it can be used.

  As shown in FIG. 8, the present applicant supports the right side of a footrest d supported rotatably by a pivot shaft b installed on the left side in the drawing with respect to a base a by a drive elevating device e. A massage device capable of enhancing the massage effect by effectively stimulating the acupoints on the sole by providing lifting means (not shown) that increases the strength as the footrest d rises from the lower position to the upper position. (For example, refer to Patent Document 1).

JP 2005-218568 A

  As a result of repeated research and testing, the present applicant, when the footrest is vibrated with a large amplitude of about 6.0 to 24.0 mm, unlike the small amplitude of the sole massager, It was discovered that the following excellent effects can be obtained that cannot be obtained by: In other words, because the user's whole body moves up and down violently, not only the legs but also the whole body including the upper body is stimulated, energy consumption is increased and a shape-up effect is obtained, and metabolism is promoted to promote the whole body. Is activated. At the same time, the muscles can be effectively stimulated to improve muscle strength.

  However, if a large amplitude exceeding 6.0 mm is set using the structure of the massaging device shown in FIG. 8, the right side of the footrest d supported by the pivot shaft b on the left side in the drawing greatly moves up and down at a high speed. Therefore, a large inertial force acts repeatedly. As a result, the entire apparatus including the base a placed on the floor surface is rattled up and down, generating a large noise, and causing a phenomenon that the massage device is displaced while vibrating on the floor surface, There is a risk that the user on the footrest d falls.

  Further, in order to generate a high-speed vibration motion with an amplitude exceeding 6.0 mm in a state where the weight of the user is placed on the footrest d supported on one side, it is necessary to use a driver with a considerably large horsepower. As the equipment becomes larger, the noise during operation increases. Alternatively, since a large load acts on the operating mechanism, frequent maintenance is necessary to prevent failure.

  The present invention provides a seesaw vibration in which an eccentric part of a rotating shaft that is rotated by a driver moves a footrest up and down through a connecting rod so that the footrest rises and lowers alternately around a support shaft. It is an object to provide a vibration health device that is compact and easy to use because it can be used safely because it repeats a smooth raising and lowering motion even with a large amplitude motion.

  As shown in FIGS. 2 and 3, the base frame 26 is slightly lifted above the substrate 24 by the short columnar upper rubber feet 25 fixed on the substrate 24 supporting the wing pieces 26C. Mounted at height. Accordingly, the base frame 26 is supported by the lower rubber foot 23 and the upper rubber foot 25 with double cushioning.

  The footrest 3 includes a mounting plate 27 that directly receives a user's foot, and a pair of reinforcing angles 28 fixed to the lower portion to reinforce the mounting plate 27. The mounting plate 27 has a reverse basin shape in which a short hanging piece is formed on the entire periphery, and is an olefin resin, polystyrene resin, phenol resin, unsaturated polyester resin containing polyethylene resin, polypropylene resin, ethylene vinyl acetate resin (EVA). It is integrally molded using a plastic material such as chloroprene rubber CR), styrene / butadiene rubber (SBR), isoprene rubber (IR) on a metal core such as a steel plate, styrene / olefin / It is formed by coating an elastic material such as urethane-based / polyester-based thermoplastic elastomer, ethylene vinyl acetate copolymer (EVA), or the like.

The distal end portion of each support shaft 5 is pivotally supported by the bearing unit 30. Since it is configured in this manner, the footrest 3 is configured such that the center in the left-right direction is pivotally supported by the support shaft 5 and the left and right ends are alternately swingable up and down.

  As shown in FIG. 4, the driving means 4 includes a vertical motion unit 6 and a driver 7 that moves the vertical motion unit 6. The vertical motion unit 6 is arranged to be displaced to the left or right with respect to the support shaft 5 disposed at the center, and includes a rotating shaft 9 and a connecting rod 10. In addition, the vertical motion part 6 of this form is displaced and arrange | positioned on the right side.

  As shown in FIGS. 3 and 6, the rotating shaft 9 is formed with an eccentric portion 8 in the middle portion and faces in the front-rear direction, and both ends thereof are horizontally supported by the bearing units 31 and 31 at the ends, In the meantime, a driven pulley 37 is provided.

  The eccentric portion 8 has a circular longitudinal section and is formed to have a larger shaft diameter than the other portions. In this embodiment, a pair is formed before and after the rotating shaft 9. The eccentric portion 8 is formed with a displacement of, for example, about 3.0 to 12.0 mm, preferably 4.5 to 9 mm, and 6.0 mm in this embodiment with respect to the rotation center of the rotation shaft 9. When the displacement dimension is less than 3.0 mm, the amplitude S of the footrest 3 is less than 6.0 mm, and the vibration given to the user who is placed on the footrest is too small, so that the health promotion effect such as body shape is insufficient. On the other hand, if it exceeds 12.0 mm, an amplitude S exceeding 24.0 mm is generated, so that an excessively vigorous vibration is generated and a loud vibration sound is generated to promote health.

  A lower part of the connecting rod 10 is rotatably attached to the eccentric part 8 of the rotating shaft 9, and an upper part is pivotally attached to the lower part of the footrest 3 above the rotation center of the rotating shaft 9. In this embodiment, as shown in FIG. 6, a ring-shaped bearing 11 that is extrapolated to the eccentric portion 8 of the rotating shaft 9 and a bearing housing H that accommodates the bearing 11 and has a horizontal small end hole 12 at the top. A connecting rod 10 consisting of In the connecting rod 10 of this embodiment configured as described above, the bearing 11 can be accommodated in the interior for easy assembly, and when trouble occurs, the bearing 11 can be removed for easy maintenance.

  In this embodiment, as shown in FIGS. 5 and 6, the upper end of the connecting rod 10 is attached to the small end hole 12 by pivotally inserting a receiving shaft 13 provided at the lower portion of the footrest 3. Therefore, the footrest 3 can be stably supported by the connecting rod 10.

  The bearing 11 of this embodiment uses a ball bearing including an outer ring 11A, an inner ring 11B, and a plurality of balls 11D arranged in a ring shape between the two rings. The connecting rod 10 is extrapolated to the eccentric part 8 by the inner ring 11 </ b> B being fitted on the eccentric part 8. Other bearings 11 such as roller bearings and sliding bearings can also be used.

  In the bearing housing H of this embodiment, a large ring-shaped housing main body 14 that accommodates the bearing 11 therein and a small ring portion 15 that is continuous with the upper portion of the housing main body 14 are integrally formed. Thus, the small end hole 12 is configured. As shown in FIGS. 5 and 6, the receiving shaft 13 of the footrest 3 is inserted through the small ring portion 15 to connect the rotary shaft 9 and the footrest 3. As described above, the bearing housing H of the present embodiment is formed firmly and integrally with the housing main body 14 and the small ring portion 15. Therefore, even if a large load is applied, the bearing housing H may be deformed or damaged. This is preferable in that a small connecting rod 10 having excellent reliability can be obtained.

  As shown in FIGS. 3 and 4, a pair of connecting rods 10 are arranged side by side in the vicinity of both ends of the rotating shaft 9, corresponding to the eccentric portion 8 provided with a pair of front and rear as described above. Thus, when the eccentric part 8 and the connecting rod 10 to be extrapolated to the eccentric part 8 are provided in the vicinity of both ends of the rotating shaft 9 pivotally supported by the base 2, the center part is supported by the support shaft 5. Since the base 3 can be stably supported, the footrest 3 can be smoothly swung.

  As shown in FIG. 6, the bearing housing H of this embodiment is formed by using first and second bearing housing members H1 and H2 that are vertically divided into two. Each of the first and second bearing housing members H1 and H2 has a large-diameter annular portion 16 and a small ring portion 34 integrally formed above the annular portion 16, and is substantially symmetrical with each other. It has a shape. The annular portion 16 is further formed with a flange portion 17 extending integrally from the outer peripheral edge toward the inside with a constant small width. The first and second bearing housing members H1 and H2 configured in this manner are fixedly integrated using the fixing tool 41 with the flanges 17 arranged on the outside, thereby forming a circular void inside. It is formed, and the bearing 11 can be accommodated in this space without a gap.

  As described above, by assembling the first and second bearing housing members H1 and H2 that are divided vertically, the bearing housing H that forms a space for accommodating the bearing 11 therein can be assembled and disassembled freely. Therefore, the maintenance of the bearing 11 can be easily performed. Further, in this embodiment, since the bearing housing H is assembled by arranging the flange portions 17 of the first and second bearing housing members H1 and H2 on the outside, the bearing 11 is provided between the flange portions 17. Is housed in a stable state sandwiched between the two.

  In this embodiment, the driver 7 uses an electric motor M. As shown in FIG. 4, the electric motor M has a motor shaft 35 that faces in the front-rear direction and is aligned with the support shaft 5 at the center in the left-right direction, and is fixed on the base frame 26. Since the electric motor M is arranged at the substantially right and left central portion of the footrest 3 in this way, the weight of the electric motor M is applied to the central portion of the vibration health device 1, so that it is stable with a device that vibrates vigorously. It is preferable in that it can be installed.

  As the electric motor M, an AC motor, an induction motor, a DC motor, a brushless motor, or the like can be used. In this embodiment, an AC motor operating with a household 100 volt power supply is used, and rotation is controlled by a control circuit (not shown). The control circuit controls on / off of the motor, the number of revolutions, and the like. Further, by using a microcomputer, the rotation speed can be gradually increased or decreased according to the program conditions, or the rotation can be controlled by receiving a signal from a sensor for detecting a change in load or the like. As shown in FIG. 1, these control circuits can be operated by inputting to a control box 40 provided at the upper end of a column 39 standing on the front part of the base 2.

  A driving pulley 36 is attached to the motor shaft 35, and a drive transmission belt 38 is wound between the motor shaft 35 and the driven pulley 37 of the rotating shaft 9, so that the rotating shaft 9 is connected to the electric motor M. Driven to rotate. Therefore, when the bulging part of the eccentric part 8 rotates around the axis of the rotary shaft 9, the connecting rod 10 including the bearing 11 extrapolated to the eccentric part 8 moves up and down following the movement. The footrest 3 supported on the right side by the connecting rod 10 repeats so-called seesaw vibration in which the left and right are balanced and alternately rise and fall with the support shaft 5 pivotally supporting the left and right centers as the center.

  That is, as shown in FIG. 7A, in the rotational phase where the bulging portion of the eccentric portion 8 is at the upper position, the right side of the footrest 3 rises to the highest position of the amplitude S and the right side is raised upward. Tilt. Further, in the rotation phase in which the bulging portion of the eccentric portion 8 in which the rotation shaft 9 is rotated 90 degrees is on the right side, the footrest 3 returns to the horizontal reference position as shown in FIG. Further, when the rotation shaft 9 rotates 90 degrees and the bulging portion of the eccentric portion 8 advances to a lower rotational phase, the right side of the footrest 3 is the lowest position of the amplitude S as shown in FIG. Descend to the right and tilt down on the right. Further, when the rotation shaft 9 rotates 90 degrees and the bulging portion of the eccentric portion 8 changes to the rotation phase on the left side, the footrest 3 returns to the horizontal reference state. The so-called seesaw vibration in which the left and right are alternately moved up and down around the support shaft 5 is repeated by the continuous rotation of the rotating shaft 9.

  The frequency of the seesaw vibration as described above is controlled by the number of rotations of the electric motor M controlled by the control circuit, and is, for example, about 600 to 2000 rpm, preferably about 800 to 1600 rpm. If it is less than 600 rpm, the vibration stimulation given to the user becomes too small, so that the health promotion effect such as body shape is insufficient. On the other hand, if it exceeds 2000 rpm, the vibration speed becomes excessively high for health promotion, and the use environment is impaired, for example, noise increases.

  As shown in FIGS. 2 and 3, a substantially cylindrical casing 42 surrounding movable parts such as the up-and-down moving part 6 and the electric motor M is fixed on the substrate 24 of the base 2 to ensure safety and appearance. It is increasing.

  As described above, the footrest 3 of the vibration health device 1 is pivotally supported by the support shaft 5 disposed substantially in the center in the left-right direction, and repeats seesaw vibration in which the left and right sides are alternately moved up and down by the driver 7. The weight of the user who puts his / her left and right feet on the table 3 is distributed and supported across the support shaft 5. At the same time, the seesaw vibration of the footrest 3 is such that when one side rises, the opposite side descends to balance the load on the left and right, and the inertia force in the vertical direction cancels out. Is suppressed. As a result, noise can be relatively suppressed even during high-speed movement of about 600 to 2000 rpm, and the footrest 3 can smoothly repeat the seesaw-like lifting movement, even in a large amplitude movement exceeding 6.0 mm, The user on the footrest can continue the whole body exercise for health promotion safely.

  In addition, the weight of the user who is placed on the footrest 3 pivotally supported by the substantially central support shaft 5 is balanced on the left and right with the support shaft 5 in between, and the load when rising on one side can be offset by the load on the opposite side. Therefore, the seesaw vibration can be driven with a small force. Accordingly, even when driving a motion with an amplitude exceeding 6.0 mm in a high-speed cycle, the driver 7 having a relatively small horsepower can be used, so that the entire apparatus can be made compact and the driving sound can be reduced. Furthermore, since the load applied to the motion mechanism is reduced, mechanical troubles are reduced and maintenance can be performed easily.

  The above description is an example of the embodiment of the present invention. Therefore, the technical scope of the present invention is not limited to this, and various modifications are included in addition to the above-described embodiment.
