Passive exercise assisting device of standing type

Abstract

A passive exercise assisting device comprises a left foot support, a right foot support, and a driving unit. The left foot support and the right foot support are configured to bear a left foot and a right foot of a user respectively. The driving unit is configured to move the left foot support and the right foot support so as to give motions to the left foot support and the right foot support in relation with each other. The driving unit comprises at least one of a horizontal motion applying mechanism and a rotation motion applying mechanism. The horizontal motion applying mechanism is configured move the left foot support and the right foot support laterally to the left foot support and the right foot support. The rotation motion applying mechanism is configured rotate the left foot support and the right foot support about horizontal axes to the left foot support and the right foot support. The passive exercise assisting device further comprises a vertical motion applying mechanism being configured to move the left foot support and the right foot support vertically to the left foot support and the right foot support.

1 . A passive exercise assisting device of standing type comprising:
 a left foot support and a right foot support being configured to bear a left foot and a right foot of a user respectively;   a driving unit being configured to move said left foot support and said right foot support so as to give motions to said left foot support and said right foot support in relation with each other;   said driving unit comprising at least one of a horizontal motion applying mechanism and a rotation motion applying mechanism, said horizontal motion applying mechanism being configured to give horizontal motions to said left foot support and said right foot support such that said horizontal motion applying mechanism moves said left foot support and said right foot support in a horizontal direction, said rotation motion applying mechanism being configured to give rotation motions to said left foot support and said right foot support such that said rotation motion applying mechanism rotates said left foot support and said right foot support about horizontal axes along the horizontal direction,   wherein   said driving unit comprises a vertical motion applying mechanism being configured to give vertical motions to said left foot support and said right foot support such that said vertical motion applying mechanism moves said left foot support and said right foot support in a vertical direction, and   said vertical motion applying mechanism being configured to give the vertical motions to said left foot support and said right foot support in synchronization with the horizontal motions or the rotation motion.   
     
     
         2 . The passive exercise assisting device as set forth in  claim 1 , wherein
 said driving unit being configured to move said left foot support and said right foot support such that said left foot support is interlocked with said right foot support.   
     
     
         3 . The passive exercise assisting device as set forth in  claim 1 , wherein
 said vertical motion applying mechanism comprises a vertical motion applying means which is configured to move said left foot support and said right foot support in the vertical direction, and   said vertical motion applying means being configured to move said left foot support and said right foot support in order to vary height of said left foot support relative to said right foot support.   
     
     
         4 . The passive exercise assisting device as set forth in  claim 1 , wherein
 said left foot support and said right foot support are configured to be rotatable about a rotation axis which is perpendicular to a horizontal plane.   
     
     
         5 . The passive exercise assisting device as set forth in  claim 1  further comprises a rotation plate,
 said rotation plate having a rotation axis which is perpendicular to a horizontal plane,   said rotation plate being rotated about said rotation axis,   both said left foot support and said right foot support are attached to said rotation plate,   whereby said left foot support and said right foot support are rotated when said rotation plate is rotated,   said rotation axis being located between said left foot support and said right foot support.   
     
     
         6 . The passive exercise assisting device as set forth in  claim 3 , wherein
 said vertical motion applying means being configured to give the vertical motion to said left foot support and said right foot support in order to move said left foot support and said right foot support downward as said horizontal motion applying mechanism gives the horizontal motion to said left foot support and said right foot support in order to move said left foot support and said right foot support frontward from backward.   
     
     
         7 . The passive exercise assisting device as set forth in  claim 3 , wherein
 said vertical motion applying means is configured to give the vertical motion to said left foot support in order to move said left foot support downward as said rotation motion applying mechanism gives the rotation motion to said left foot support in order to move said left foot support from a frontward tilting posture to a backward tilting posture, and   said vertical motion applying means is configured to give the vertical motion to said right foot support in order to move said right foot support downward as said rotation motion applying mechanism gives the rotation motion to said right foot support in order to move said right foot support from a frontward tilting posture to a backward tilting posture.   
     
     
         8 . The passive exercise assisting device as set forth in  claim 3 , wherein
 said vertical motion applying means is configured to give the vertical motion to said left foot support in order to move said left foot support downward as said rotation motion applying mechanism gives the rotation motion to said left foot support in order to move said left foot support from a backward tilting posture to a frontward tilting posture, and   said vertical motion applying means is configured to give the vertical motion to said right foot support in order to move said right foot support downward as said rotation motion applying mechanism gives the rotation motion to said right foot support in order to move said right foot support from a backward tilting posture to a frontward tilting posture.
