Bounce board exerciser

A bounce board exerciser comprising

• a housing;
• a platform pivotally mounted in said housing on a horizontal axis to receive a user for up and down movement;
• spring means within said housing operatively connected to and supporting said platform in a raised position relative to said housing and for balancing the weight of a user thereon;
• and
• energy dissipation means in said housing connected to and between said platform and said housing for dissipating energy delivered thereto in response to a movement of said platform caused by the user.

A bounce board exerciser comprising

• a support;
• at least one platform movably mounted on said support for up and down movement;
• a lever frame pivotally mounted on one end of said support and secured to said platform at an opposite end for pivotally mounting said platform relative to said support;
• spring means connected to and between said support and said lever frame for supporting said platform;
• means for adjusting said spring means longitudinally of said lever frame to cause said platform to settle at a predetermined elevation for a given load on said platform;
• means for changing the length of said spring means to vary the pressure force thereof;
• and
• energy dissipation means connected to said platform for dissipating energy delivered thereto in response to a movement of said platform.

A bounce board exerciser comprising

• a support;
• at least one platform movably mounted on said support for up and down movement;
• a lever frame pivotally mounted at one end of said support and secured to said platform at an opposite end for pivotally mounting said platform relative to said support;
• a handle assembly mounted on said support and including a handle bar articulated to said lever frame for moving in an opposite direction to a pivoting movement of said lever frame;
• spring means for supporting said platform;
• and
• energy dissipation means connected to said platform for dissipating energy delivered thereto in response to a movement of said platform.

A bounce board exerciser comprising

• a support;
• at least one platform movably mounted on said support for up and down movement;
• spring means for supporting said platform;
• a shock absorber having a variable stroke connected to said platform for dissipating energy delivered thereto in response to a movement of said platform;
• means for measuring the rate at which energy is dissipated in said shock absorber, said measuring means including a device for measuring the change of length in said stroke of said shock absorber and emitting a corresponding signal, a differentiator to receive and differentiate said signal, a cubing circuit to cube the differentiated signal, a rectifier for rectifying said signal from said differentiator and said cubing circuit and an averager connected to said cubing circuit to average the cubed and rectified signal for emission therefrom;
• and
• read-out means connected to said averager of said measuring means for displaying a value indicative of said rate in response to said signal from said averager.

A bounce board exerciser comprising

• a support;
• at least one platform movably mounted on said support for up and down movement;
• spring means for supporting said platform;
• energy dissipation means connected to said platform for dissipating energy delivered thereto in response to a movement of said platform;
• and
• a handle assembly mounted on said support and including a handle articulated to said platform for moving in an opposite direction to the movement of said platform.
