Passive Exercise Equipment

Abstract

This aims to provide passive exercise equipment capable of securing constant sense of use so as to avoid variation in depressing feel against sole-surmounted parts irrespective of body type difference among users. The equipment has a seat 2 for resting a user M on the buttocks, right and left footstools 3 for resting the right and left soles of user M sitting on seat 2 on, and a seat driver 5 for changing the position of seat 2 position to change load balance added to seat 2 and footstools 3 by user M, thereby changing the user's own weight acting on the legs. Each footstool 3 includes a sole-surmounted part 4 which a sole is placed on and meanwhile can be moved up and down, an elastic device 6 for biasing sole-surmounted part 4 upward; and a bias adjuster 7 for adjusting an elastic coefficient of elastic device 6.

1 . Passive exercise equipment, comprising:
 a seat configured to rest a user on the buttocks;   right and left footstools configured to rest the right and left soles of the user sitting on the seat on; and   a seat driver configured to change the position of the seat to change load balance added to the seat and the footstools by the user and thereby to change the user's own weight acting on the legs,   wherein each footstool comprises:   a sole-surmounted part which a sole is placed on and meanwhile can be moved up and down;   an elastic device configured to bias the sole-surmounted part upward; and   a bias adjuster configured to adjust an elastic coefficient of the elastic device.   
     
     
         2 . The passive exercise equipment of  claim 1 , comprising:
 a body weight input part configured to input body weight of the user;   regulatory drivers configured to drive the bias adjusters to adjust elastic coefficients of the elastic devices, respectively; and   a controller configured to perform drive control of the regulatory drivers in response to the body weight input though the body weight input part.   
     
     
         3 . The passive exercise equipment of  claim 1 , comprising:
 a body weight detector configured to detect body weight of the sitting user;   regulatory drivers configured to drive the bias adjusters to adjust elastic coefficient of the elastic devices, respectively; and   a controller configured to perform drive control of the regulatory drivers in response to the body weight detected though the body weight detector.   
     
     
         4 . The passive exercise equipment of  claim 1 ,
 wherein said elastic device comprises a plurality of spring members arranged between said sole-surmounted part and a base part of said footstool,   said plurality of spring members comprising an unconnected spring member having an unconnected end which is not connected to said base part or said sole-surmounted part in a nature state,   wherein said bias adjuster comprises a member switchable between states in which the member is connected to and disconnected from both the unconnected end of said unconnected spring member and said base part or said sole-surmounted part.   
     
     
         5 . The passive exercise equipment of  claim 2 ,
 wherein said elastic device comprises a plurality of spring members arranged between said sole-surmounted part and a base part of said footstool,   said plurality of spring members comprising an unconnected spring member having an unconnected end which is not connected to said base part or said sole-surmounted part in a nature state,   wherein said bias adjuster comprises a member switchable between states in which the member is connected to and disconnected from both the unconnected end of said unconnected spring member and said base part or said sole-surmounted part.   
     
     
         6 . The passive exercise equipment of  claim 3 ,
 wherein said elastic device comprises a plurality of spring members arranged between said sole-surmounted part and a base part of said footstool,   said plurality of spring members comprising an unconnected spring member having an unconnected end which is not connected to said base part or said sole-surmounted part in a nature state,   wherein said bias adjuster comprises a member switchable between states in which the member is connected to and disconnected from both the unconnected end of said unconnected spring member and said base part or said sole-surmounted part.
