Balance Fitness Machine

Abstract

A balance fitness machine is provided which is capable of automatically and stably and also uniformly effecting muscle exercise and stretch exercise and exercise for increasing sense of balance. This balance fitness machine has a platform 1 capable of carrying a user H mounting thereof in a standing posture, a rocking mechanism 2 for rocking this platform 1 in front-rear, left-right, and up-down directions, and a drive motor 20 for driving this rocking mechanism 2 . The platform 1 has a long-by-narrow shape and is linked to the rocking mechanism 2 through support members 48 formed of resilient bodies.

1 . A balance fitness machine comprising: 
 a platform capable of carrying a user mounting thereon in a standing posture;    a rocking mechanism for rocking the platform in a front-rear, left-right, or up-down direction; and    driving means for driving the rocking mechanism.    
   
   
       2 . A balance fitness machine according to  claim 1 , wherein the platform has a long-by-narrow shape.  
   
   
       3 . A balance fitness machine according to  claim 1 , wherein the platform is connected to the rocking mechanism through a supporting member formed of a resilient body.  
   
   
       4 . A balance fitness machine according to any one of  claims 1  to  3 , wherein the rocking mechanism is disposed below the platform and the driving means is disposed on a side of the rocking mechanism.  
   
   
       5 . A balance fitness machine according to  claim 4 , wherein the rocking mechanism comprises: 
 a support plinth on which the platform is mounted;    a first support shaft and a second support shaft that support the support plinth from below; and    a support part that supports the first support shaft and the second support shaft,    the first support shaft having a first axle projecting from both ends in an axial direction thereof for eccentrically rotatably supporting the first support shaft,    the second support shaft having a second axle projecting from both ends in an axial direction thereof for oscillatably supporting the second support shaft,    the first axle and the second axle being supported by the support part horizontally and with a predetermined spacing between them.    
   
   
       6 . A balance fitness machine according to  claim 5 , wherein the driving means rotationally drives the first axle of the first support shaft of the rocking mechanism.  
   
   
       7 . A balance fitness machine according to  claim 6 , wherein 
 the rocking mechanism has oscillating means for oscillating the support plinth in the axial direction of the first support shaft,    the oscillating means comprising:    an oscillating member connected to the support plinth;    a slide support shaft disposed along the axial direction of the first support shaft for slidably supporting the oscillating member; and    a guide member for oscillating the oscillating member along the slide support shaft,    the guide member being formed in a cylindrical shape and being rotatable about an axis parallel with the axis of the first support shaft, the guide member having an outer circumferential face formed with a spiral cam groove,    the oscillating member being provided with a guide pin to be slidably fitted in the cam groove.    
   
   
       8 . A balance fitness machine according to  claim 6 , wherein 
 the rocking mechanism has oscillating means for oscillating the support plinth in the axial direction of the first support shaft,    the oscillating means comprising:    an oscillating member connected to the support plinth;    a slide support shaft disposed along the axial direction of the first support shaft for slidably supporting the oscillating member; and    a guide member for oscillating the oscillating member along the slide support shaft,    the guide member being formed in a cylindrical shape and being rotatable about an axis parallel with the axis of the first support shaft, the guide member having an outer circumferential face formed with a spiral cam groove,    the oscillating member being provided with a guide pin to be slidably fitted in the cam groove,    the first axle, the second axle, and the guide member being disposed such as to be horizontally parallel to each other.    
   
   
       9 . A balance fitness machine according to  claim 6 , wherein 
 the rocking mechanism has oscillating means for oscillating the support plinth in the axial direction of the first support shaft,    the oscillating means comprising:    an oscillating member connected to the support plinth;    a slide support shaft disposed along the axial direction of the first support shaft for slidably supporting the oscillating member; and    a guide member for oscillating the oscillating member along the slide support shaft,    the guide member being formed in a cylindrical shape and being rotatable about an axis parallel with the axis of the first support shaft, the guide member having an outer circumferential face formed with a spiral cam groove,    the oscillating member being provided with a guide pin to be slidably fitted in the cam groove,    the ratio of the rotational speed of the guide member to the rotational speed of the first axle being set as 1:2.
