Auxiliary exercise equipment

Abstract

An auxiliary exercise equipment comprises a footrest for supporting a foot of a user. The footrest is configured so that a part of the footrest relatively retreats from a remaining part of the footrest and thereby is made apart from the foot while the remaining part of the footrest supports the foot.

1 . An auxiliary exercise equipment, comprising a footrest for supporting a foot of a user,
 wherein the footrest is configured so that a part of the footrest relatively retreats from a remaining pan of the footrest and thereby is made apart from the foot while the remaining pan of the footrest supports the foot.   
     
     
         2 . The auxiliary exercise equipment as claimed in  claim 1 , wherein the footrest comprises a plurality of members,
 wherein the footrest is configured so that at least one of the plurality of members is bent with respect to a remaining member(s) of the plurality of members and thereby is made apart from the user's foot.   
     
     
         3 . The auxiliary exercise equipment as claimed in  claim 2 , wherein the plurality of members of the footrest are separately arranged back and forth. 
     
     
         4 . The auxiliary exercise equipment as claimed in  claim 3 , wherein the plurality of members of the footrest are a front half and a back half,
 wherein the footrest is configured so that the front half is bent downward with respect to the back half.   
     
     
         5 . The auxiliary exercise equipment as claimed in  claim 3 , wherein the plurality of members of the footrest are a front half and a back half,
 wherein the footrest is configured so that the back half is bent downward with respect to the front half.   
     
     
         6 . The auxiliary exercise equipment as claimed in  claim 2 , wherein the plurality of members of the footrest are separately arranged to right and left. 
     
     
         7 . The auxiliary exercise equipment as claimed in  claim 6 , wherein the plurality of members of the footrest are an inside half and an outside half,
 wherein the footrest is configured so that the inside half is bent downward with respect to the outside half.   
     
     
         8 . The auxiliary exercise equipment as claimed in  claim 6 , wherein the plurality of members of the footrest are an inside half and an outside half,
 wherein the footrest is configured so that the outside half is bent downward with respect to the inside half.   
     
     
         9 . The auxiliary exercise equipment as claimed  claim 1 , wherein the footrest is configured so as to support the user's foot in the standing position. 
     
     
         10 . The auxiliary exercise equipment as claimed in  claim 1 , further comprising:
 a foot support platform for supporting the footrest;   a seat for supporting buttocks of the user while a sole of the user is rested on a rest surface of the footrest; and   a seat driving unit being configured to displace the seat by using a driving source so as to change a weight acting, on a use's leg by the user's body weight;   wherein the foot support platform comprises a supporting base located in a fixed position, and a supporting mechanical part configured to support the footrest with respect to the supporting base while biasing the footrest upward so that the footrest can reciprocate in the vertical direction,   wherein the rest-surface of the footrest is formed so as to slant downward along the direction from a heel of the user toward a toe of the user,   wherein the supporting mechanical part is configured to relatively move a part of the back of the footrest larger than a part of the front of the footrest when the weight acting on the user's leg by the user's body weight increases.   
     
     
         11 . The auxiliary exercise equipment as claimed in  claim 10 , further comprising:
 a detector for detecting a muscle activity of the user's leg and   a controller being configured to control a movement distance of the footrest moved by the supporting mechanical part according to a result of the muscle activity detected by the detector.   
     
     
         12 . The auxiliary exercise equipment as claimed in  claim 11 , wherein the detector is configured to detect a muscle activity of either hamstrings or triceps surae muscles of the user, the hamstrings including a biceps femoris muscle, a semimembranosus muscle and a semitendinosus muscle, the triceps surae muscles including a gastrocnemius muscle and a soleus muscle. 
     
     
         13 . The auxiliary exercise equipment as claimed in  claim 2 , wherein the footrest is configured so as to support the user's foot in the standing position. 
     
     
         14 . The auxiliary exercise equipment as claimed in  claim 3 , wherein the footrest is configured so as to support the user's foot in the standing, position. 
     
     
         15 . The auxiliary exercise equipment as claimed in  claim 4 , wherein the footrest is configured so as to support the user's foot in the standing position. 
     
     
         16 . The auxiliary exercise equipment as claimed in  claim 5 , wherein the footrest is configured so as to support the user's foot in the standing position. 
     
     
         17 . The auxiliary exercise equipment as claimed in  claim 6 , wherein the footrest is configured so as to support the user's foot in the standing position. 
     
     
         18 . The auxiliary exercise equipment as claimed in  claim 7 , wherein the footrest is configured so as to support the user's foot in the standing position. 
     
     
         19 . The auxiliary exercise equipment as claimed in  claim 8 , wherein the footrest is configured so as to support the user's foot in the standing position.
