Abstract
An exercise device 10 is particularly well suited for use in low gravity environments, and includes a frame 12 with plurality of resistance elements 30, 82 supported in parallel on the frame. A load transfer member 20 is moveable relative to the frame for transferring the applied force to the free end of each captured resistance element. Load selection template 14 is removably secured both to the load transfer member, and a plurality of capture mechanisms engage the free end of corresponding resistance elements. The force applying mechanism 53 may be a handle, harness or other user interface for applying a force to move the load transfer member.
Claims31
A resistive exercise device, comprising:
- a frame;
- a plurality of resistance elements each supported on the frame, each resistance element having a supported end attached to the frame and a free end opposite the supported end, the free end being movable relative to the supported end in response to an applied force provided by a user and wherein each of the plurality of resistance elements is a linear resistance element whose force increases substantially linearly over a displacement range of the free end relative the supported end;
- a load transfer member, movable relative to the frame, for transferring the applied force to the free end of the at least one resistance element;
- a load selection template removably securable to the load transfer member;
- a plurality of capture mechanisms, each selected capture mechanism engaging the free end of a corresponding resistance element, such that the applied force to the load transfer member moves the load transfer member to displace the free end of each engaged resistance element;
- and
- a force applying mechanism for applying the applied force to move the load transfer member.
