Abstract
A gymnastic training device has a first substantially horizontal support and a substantially vertical support member, the upper end of the substantially vertical support member is rotatably mounted on the lower side of the first substantially horizontal support. A ground engaging wheel is mounted to the lower end of the substantially vertical support member. The gymnastic training device also has a second substantially horizontal support which is fixedly mounted on the substantially vertical support member between the ground engaging wheel and the first substantially horizontal support.
Claims24
A gymnastic balancing training device comprising:
- (a) first substantially horizontal support platform defining an upper side and a lower side, said lower side having a central portion;
- (b) a substantially vertical support member having first and second ends, said first substantially horizontal support means mounted on one end of said support member within said central portion;
- (c) means for permitting rotation of said first substantially horizontal support platform in a substantially horizontal plane about said substantially vertical support member;
- (d) ground engaging wheel means mounted to the other end of said substantially vertical support member;
- (e) a generally horizontal second substantially horizontal support platform defining an upper side a lower side and a second central portion;
- and
- (f) three rotatably mounted wheel means attached to said lower side of said second substantially horizontal support platform, said rotatably mounted wheel means spaced to define a triangle which encompasses said ground engaging wheel means, the lowermost portion of said ground engaging wheel means being lower than the lowermost portion of each of said rotatably mounted wheel means when the plane defined by said rotatably mounted wheel means is horizontal;
- said substantially vertical support member and said ground engaging wheel means being adapted to co-operate with said first substantially horizontal support platform to provide a mobile surface for the user to balance upon, said substantially vertical support member being attached to said second substantially horizontal support platform within said central portion at a location on said substantially vertical support member between said ground engaging wheel means and said first substantially horizontal support platform.
