System for exercising the lower extremities in seated persons

A system for exercising lower extremities of a seated person, comprising:

• a motorized base having a housing;
• a wheel mounted to be driven by said motorized base;
• an eccentric pivot mounted on said wheel;
• a connecting rod connected to said eccentric pivot;
• a radial arm connected to said connecting rod;
• two supports on said housing in a longitudinal and median alignment;
• a freely rotatable axle held in said two supports;
• a transverse support firmly joined to said freely rotatable axle;
• and
• said support surfaces firmly joined to ends of said transverse support to that said support surfaces rock laterally and jointly with said axle.

A system for exercising lower extremities of a seated person, comprising:

• a motorized base having a housing;
• two supports extending from said motorized base in longitudinal and median alignment;
• a longitudinal axle on said two supports;
• a connecting rod connected at one end of said longitudinal axle;
• a drive wheel connected to drive said connecting rod;
• a first transverse am firmly connected to said longitudinal axle a second axle on said two supports under said first transverse arm;
• a second transverse arm firmly connected to said second axle, said second transverse arm being parallel to said first transverse arm;
• and
• vertical arms joining respective ends of said first transverse am to said second transverse arm;
• said support surfaces having said respective vertical arms emerging from lower faces of said support surfaces, said first and second transverse arms and said vertical arms forming a deformable parallelogram in which said vertical arms retain verticality during rocking of said first and second transverse arms delivered by rocking of said longitudinal axle.

A system for exercising lower extremities of a seated person, comprising:

• a motorized base;
• a support surface for a user's feet including a support bar with an external jacket which turns freely with respect to said support bar;
• two arms connected by a common turning axle and having said support bar mounted between respective ends of said two arms;
• a joining connecting rod connected to an opposite end of one of said two arms;
• a rotating wheel connected to said joining connecting rod by an eccentric;
• and
• a drive driven by said motorized base and connected to said rotating wheel so that movement is transmitted so that a user's feet rested on said support surface are subject to movement, said movement being at least one of vertical movement and horizontal movement and rocking movement.

A system for exercising lower extremities of a seated person, comprising:

• a motorized base having a housing;
• a wheel mounted to be driven by said motorized base;
• an eccentric pivot mounted on said wheel;
• a connecting rod connected to said eccentric pivot at a first end and having a second end with a pivot;
• and
• a support surface mounted on said housing for sliding movement and connected to said pivot at said second end of said connecting rod so that a user's feet rested on said support surfaces are subject to movement, said movement being at least one of vertical movement and horizontal movement and rocking movement.

A system for exercising lower extremities of a seated person, comprising:

• a motorized base having a housing;
• a transverse axle connected to be driven by said motorized base;
• two wheels coupled to said transverse axle for rotation;
• two eccentric pivots mounted on respective ones of said two wheels;
• and
• two support surfaces connected to respective ones of said two eccentric pivots, said two support surfaces providing surfaces on which feet of a user are rested to provide movements of the user's feet, said movements being at least one of vertical movement and horizontal movement and rocking movement.

• a wheel mounted to be driven by said motorized base;
• an eccentric pivot mounted on said wheel;
• a connecting rod connected to said eccentric pivot;
• a radial arm connected to said connecting rod;
• two supports on said housing in a transverse alignment;
• a freely rotatable axle held in said two supports, said radial arm being connected to said freely rotatable axle;
• and
• a support surface for a user's feet fixed to said freely rotatable axle so that a user's feet rested on said support surface are subject to movement, said movement being at least one of vertical movement and horizontal movement and rocking movement.
