  The base portion 11 includes a substantially square base plate 11a having four corner portions as R portions, and a housing 11b fixed on the base plate 11a and having upper and lower portions opened. The center post 12 has a prismatic shape that becomes thinner as it goes upward, and a flange portion 12a formed at the lower edge of the center post 12 is fixed to the base plate 11a with a bolt (not shown).

  At the upper end of the center post 12, a control panel 13 is provided for selecting a vibration mode and displaying the remaining time. Further, from the vicinity of the upper ends of both side plates 12a of the center post 12, a pair of support bars 14 made of a pipe body are extended in a direction opposite to each other by a predetermined length. The grip portion 14a is extended and further downward to be gripped by the user for posture stabilization. Thereafter, the grip portion 14a is extended downward and further downward to reach the base plate 11a. The support bar 14 is fixed to the base plate 11a by bolts (not shown).

  In the present embodiment, a control board (control unit) for controlling the driving of the motor 10 is disposed in the center post 12, and this control board is connected to the control panel 13 at the upper end of the center post 12. Electrically connected. When the control board is disposed in the center post 12, compared with the conventional machine disposed in the base portion 11, there is an advantage in that it is less affected by vibration and less prone to failure because it is separated from the drive mechanism. Moreover, since it can be installed at a position higher than the floor surface, it is possible to reliably prevent water from splashing, and trouble of the electric system due to water (humidity) does not occur.

  As shown in FIGS. 3 to 4, a pair of brackets 15 are fixed to the lower surface of the footboard 1 with a predetermined distance apart. A hole is formed in the vicinity of the center of each bracket 15, and a swing shaft 16 is inserted into the hole of both brackets 15. Then, both end portions of the swing shaft 16 are inserted into a bearing disposed on an upper portion of a support portion 17 erected on the base plate 11a in the housing 11b. Thereby, the foot board 1 can be swung around the rocking shaft 16, that is, the left and right portions of the foot board 1 can be alternately moved up and down.

  The vibration generating mechanism 20 is a mechanism for converting the rotational force of the motor 10 into a force that vibrates the tread plate 1. As shown in FIGS. 5 to 6, the output shaft 10 a of the motor 10 is connected to the output shaft 10 a via a belt 21. The rotating shafts 22 connected to each other, the eccentric shafts 23 projecting from both end surfaces of the rotating shafts 22 and the axis thereof being eccentric from the axis of the rotating shaft 22, and the both ends of the rotating shafts 22, respectively. A movable bearing 25 having an elastic body 24 fixed thereon and a concentric arrangement with the rotary shaft 22 is disposed outside the movable bearings 25 in the axial direction of the rotary shaft 22. And a fixed bearing 26.

  A pulley 10 b is fixed near the tip of the output shaft 10 a of the motor 10, and a belt 21 is stretched between the pulley 10 b and a pulley 22 b fixed to the outer periphery of the rotary shaft 22. A plurality of V grooves are formed on the outer peripheral surfaces of the pulleys 10b and 22b, and a plurality of V belts are stretched between the V grooves. 5 to 6, a plurality of V belts are expressed as one belt for easy understanding.

  The rotary shaft 22 is rotatably supported by a pair of fixed bearings 26 fixed to the base plate 11a via an eccentric shaft 23. The fixed bearing 26 is disposed so as to be concentric with the axis of the rotary shaft 22.

  Eccentric shafts 23 project from both end faces of the rotating shaft 22, and the shaft centers of the two eccentric shafts 23 are 180 ° with respect to the axis of the rotating shaft 22 as shown in FIGS. It's off. Thus, when one end portion (left end portion in FIG. 6) of the tread plate 1 comes to the raised position, the other end portion (right end portion in FIG. 6) of the tread plate 1 comes to the lowered position. It has become.

  The eccentric shaft 23 is inserted into the inner ring of the movable bearing 25 and is fixed to a disc body (not shown) fitted in the inner ring of the fixed bearing 26. Since the rotary shaft 22 and the fixed bearing 26 are arranged so as to be concentric, the eccentric shaft 23 is eccentrically fixed to the center of the disk body and fixed to the disk body. The amount of eccentricity is the same as the amount of eccentricity of the eccentric shaft 23 with respect to the rotating shaft 22.

  As shown in FIG. 7, the movable bearing 25 holds the outer ring, the inner ring, and a bearing 25 a made up of a plurality of rolling elements that are freely rollable between the two rings, and the outer ring outer periphery of the bearing. The elastic body 24 is fixed to the upper part of the housing 25b. The elastic body 24 includes a rubber short cylindrical body 24a and fixing plates 24b and 24c provided on both end faces of the short cylindrical body 24a, respectively. The other fixing plate 24c is fixed to the upper portion of the housing 25b. Thereby, the vertical movement (vibration) of the movable bearing 25 is transmitted to the footboard 1 via the rubber short cylindrical body 24a. Thereby, a soft and continuous vibration can be given to a user.

  In the vibration generating mechanism 20 configured as described above, the rotation of the output shaft 10a of the motor 10 is decelerated and transmitted to the rotating shaft 22 via the belt 22 that is stretched between the pulley 10b and the pulley 22b. . When the rotating shaft 22 rotates, the eccentric shafts 23 protruding from both end faces of the rotating shaft 22 rotate around the axis of the rotating shaft 22 in a state of being eccentric with respect to the axis of the rotating shaft 22. Since the eccentric shaft 23 is inserted through the inner ring of the movable bearing 25, the movable bearing 25 moves up and down (vibrates) in synchronization with the rotation of the rotary shaft 22, and this vertical movement is a short cylinder made of rubber. It is transmitted to the tread board 1 through the body 24a. Instead of the pulleys and belts, the rotation of the motor 10 can be transmitted to the rotary shaft 22 using a speed reduction mechanism such as a worm or gear.

  In the present embodiment, instead of a conventional flat footboard, as shown in FIGS. 4, 6 and 8, a footboard 1 including a pair of inclined portions descending toward each other is used. The tread board 1 is formed of a substantially rectangular plate body, and includes a central convex portion 4 having left and right side surfaces 4a capable of abutting the thumbs of each foot of the user, and lower edges of the left and right side surfaces 4a. And a pair of inclined portions 3 each having an inclined surface 3 a that rises toward the end portion of the tread plate 1. In the present embodiment, the flat portion 5 is formed continuously to the outer edge of each inclined portion 3.

In the tread board 1, as shown in FIG. 8, the user touches the left and right side surfaces 4 a of the central convex portion 4 with the thumbs of each foot, respectively, so that each foot is placed on the inclined portion 3. Five fingers including the thumb can be placed.
As a result, the user can fully apply weight to each sole and can maintain a good limb position in the standing position. Further, the user can maintain a state in which the long thumb muscle which is the muscle of the big toe and the long finger muscle which is the muscle of the four fingers other than the big toe are mutually antagonistic. The weight can be correctly applied to each sole without applying an excessive load to the finger muscle and the long finger muscle.

When the central convex portion 4 is provided, the user fixes each foot using the central convex portion 4, and the femur of the right foot and the femur of the left foot are parallel to each other on the inclined portion 3. Thus, each foot can be easily arranged.
When the tread board 1 is vibrated in this state, unlike the flat tread board, when the tread board is tilted by the vibration of the tread board, the foot positioned on the lower side of the inclined surface (the one that is stretched to maintain the balance of the body) The load on the knee joint caused by the vibration of the footboard can be reduced.

  FIG. 9 is an explanatory plan view of an example of the control panel 13. A display unit 30 made up of a liquid crystal display panel or the like is provided at the upper center of the control panel 13, and mode display areas A and B are set on the left and right sides of the display unit 30, and operation buttons for mode selection 31 and 32 are arranged. The control panel 13 has a built-in voice output unit (not shown) for notifying the user of the operation procedure.

  The display unit 30 displays a message for guiding the user to use the vibration machine M, and the user performs an operation according to the voice guidance issued from the voice output unit while watching the message. Do. Specifically, the user is first guided to press either the “male” button or the “female” button. In accordance with this guidance, the user presses the “male” button 33 a or the “female” button 33 b disposed near the lower center of the control panel 13.

  Next, a message instructing selection of a vibration mode is displayed on the display unit 30 of the control panel 13, and voice guidance for prompting mode selection is issued from the voice output unit. In accordance with this guidance, the user selects a desired mode from a program mode in which vibration intensity and rhythm are programmed in advance and a manual mode in which the vibration intensity is defined in three stages. Press the operation button. Then, the selected mode is displayed on the display unit. In the manual mode, 30 levels can be set from level “1” to level “30”, but in this embodiment, intermediate levels “10”, “15”, and “20” are supported. Three operation buttons 32 are provided. As a result, the user can easily set the levels for these three levels simply by pressing the operation button 32. When it is desired to set a fine level, the level can be adjusted in increments of “1” by pressing the “up” button 36 or the “down” button 37. The user can shorten the time for level setting by using the operation button 32. It should be noted that it is possible to set a desired level only by using the “up” button 36 or the “down” button 37 without using the operation button 32.

  Next, a message for instructing to press the start button is displayed on the display unit 30, and voice guidance for pressing the button is issued from the voice output unit.

  While the machine is running, the display 30 displays the vibration “level”, “remaining time”, and “calorie consumption”. The “level” of the vibration does not indicate the absolute value of the magnitude of the vibration but is an index for relatively evaluating the magnitude of the vibration cycle. Level 1 is the vibration with the smallest cycle and therefore feels the weakest, and level 30 is the vibration with the largest cycle and therefore the strongest feeling. In addition, since this type of machine is generally controlled to operate for a predetermined time such as 10 minutes or 15 minutes, the time obtained by subtracting the actual operation time from the predetermined time is “remaining”. Displayed as “Time”. Furthermore, “calorie consumption” is displayed on the display unit 30 based on the calorie consumption data stored in advance in the storage means in the control panel 13 corresponding to each mode. The calorie consumption stored in advance in the storage means is data calculated in advance for a male or female with a standard weight, and the user can use this as reference data. In addition, by storing the data finely divided by weight and height, and letting the user input his / her weight and height before using the machine, a value closer to the actual calorie consumption of the user is displayed. 30 can be displayed.

  The vibration machine M automatically stops when the set time elapses. However, if it is desired to stop the vibration for some reason, the “STOP” button 35 at the bottom of the control panel 13 is pressed to turn off the motor 10. The rotation can be stopped. At this time, the timer for counting the “remaining time” is also temporarily stopped. When it is desired to restart the vibration, the rotation of the motor 10 can be started by pressing the “START” button 34. In this case, the operation is resumed in the same mode as before the stop.

  In addition, in the mode once selected, when it is desired to increase or decrease the “level” of vibration, by pressing the “up” button 36 or “down” button 37 provided at the bottom of each mode, Level adjustment can be made. This level can be increased or decreased in increments of “1”.

  The control panel 13 described above is merely an example, and various changes can be made according to the place of use (installation place), grade, and the like of the vibration machine M. For example, the central display unit 30 may be set large, and images of nature, animals, and the like may be played on the display unit 30. Further, various music software may be stored in the storage means of the control panel 13 so that favorite music can be enjoyed using headphones.
