Equilibrium training device

Abstract

An equilibrium training device mainly comprises a chassis, a crank component, a pedal and a revolving inertia auxiliary roller set. When the user stands on the pedal for rotary equilibrium training, the belt and the first/second rollers of the revolving inertia auxiliary roller set are pulled together in tune with the rotation of the flywheel, so the swinging uncertainty of the pedal in revolution could be eliminated, such that the pedal could swing smoothly via the inertia of its swinging path, thus avoiding falls due to loss of equilibrium and improving greatly the security, convenience and practicability.

1 . An equilibrium training device comprising:
 a chassis, defined into a preset seating pattern to form at least a plurality of seating portions; and a pin joint portion is additionally arranged on the preset location of the chassis;   a crank component, comprising of a first coupling portion and a second coupling portion in displaced configuration; of which the first coupling portion is pivoted onto the pin joint portion of the chassis, such that the second coupling portion could swing by taking the first coupling portion as the rotary pivot;   a pedal, pivoted onto the second coupling portion of the crank component; based on the connection between the second coupling portion and the pedal, the pedal can swing in a transverse circular revolution by at least taking the first coupling portion as the rotary pivot, or swing in an autorotation motion by at least taking the second coupling portion as the rotary pivot;   a revolving inertia auxiliary roller set, set between the chassis and pedal, comprising of at least a first roller, a second roller, a flywheel and a belt wound between the first and second rollers; of which the first roller and the first coupling portion of the crank component are assembled coaxially; of which the second roller is pivoted onto the chassis at one side of the first roller, while the flywheel and the second roller are assembled coaxially; when the first roller is rotated, the belt is linked with the second roller and flywheel, so the belt and the first/second rollers are pulled together with the rotation of the flywheel, and the swinging path of the pedal is of inertia;   when the user stands on the pedal to train their equilibrium sense, the swinging uncertainty of the pedal could be eliminated due to the inertia swinging path of the pedal, thus avoiding possible falls and improving the security and convenience in operation.   
     
     
         2 . The device defined in  claim 1 , wherein the axial direction of the second coupling portion of the crank component is perpendicular or oblique in relation to the ground level, so the pedal is transversely or obliquely assembled in relation to the second coupling portion; of which, when the axial direction of the second coupling portion is oblique in relation to the ground level, the pedal could swing in multiple directions in revolution or autorotation by the linking of the second coupling portion and the pedal. 
     
     
         3 . The device defined in  claim 1 , wherein at least an elastic auxiliary member is set between the pedal and chassis; both ends of said elastic auxiliary member are separately linked to the chassis and pedal, allowing to limit the pedal for only proper autorotation, during revolution of the pedal, the swinging stability and security of the pedal could be improved by the auxiliary pulling action of the elastic auxiliary member; of which, the elastic auxiliary member is preferably implemented by or not limited to either of elastic rope, spring or elastic rod. 
     
     
         4 . The device defined in  claim 3 , wherein a soft gasket is covered onto the surface of the pedal; said soft gasket is made of rubber, silica gel or soft plastics. 
     
     
         5 . The device defined in  claim 4 , wherein said pedal has an arced pattern, so that when the pedal swings in a transverse circular revolution, the users are allowed for surfing-like equilibrium training activities.
