Abstract
An adjustable reformer for exercising is provided. The reformer includes a frame, a carriage slidably mounted to the horizontal frame, and at least one resistance element connected to the carriage. A cord connects the carriage to at least one lower guide and at least one upper guide. Pulling the cord causes movement of the carriage along the frame against resistance provided by the resistance element. The guides can be height adjustable. The reformer can include a cord-length adjustment system. Related methods of exercise are also provided.
Claims20
An adjustable reformer, comprising:
- a) a frame extending horizontally along a frame axis between a frame first end and a frame second end of the frame, the frame including a pair of rails spaced laterally apart from each other and extending along the frame axis between the frame first and second ends;
- b) a carriage slidably mounted to the pair of rails so as to reciprocate along the frame axis between the frame first and second ends;
- c) a spring connector plate extending laterally across the frame between the first and second rails adjacent the frame second end, the spring connector plate adjustably mounted to the frame for adjusting an axial plate position of the spring connector plate relative to the frame second end, and the spring connector plate having a plurality of spring slots open to, and spaced laterally apart from each other along, an upper edge of the spring connector plate;
- and
- d) a plurality of springs for connecting the carriage to the spring connector plate to bias the carriage toward a carriage position between the spring connector plate and the frame first end, each spring having a spring first end connected to the carriage and a spring second end removably receivable in a respective spring slot of the spring connector plate to facilitate connection and disconnection of respective springs to the spring connector plate for adjusting spring resistance,
- wherein the spring connector plate is repositionable to any one of a plurality of different axial positions along the pair of rails, each of the different axial positions defined by a respective pair of rail slots in the pair of rails for removably receiving laterally opposed ends of the spring connector plate, and
- wherein the spring connector plate has a pair of protrusions projecting upwardly from the upper edge of the spring connector plate, each protrusion laterally adjacent a respective rail.

- and
- d) a plurality of springs for connecting the carriage to the spring connector plate to bias the carriage toward a carriage position between the spring connector plate and the frame first end, each spring having a spring first end connected to the carriage and a spring second end removably receivable in a respective spring slot of the spring connector plate to facilitate connection and disconnection of respective springs to the spring connector plate for adjusting spring resistance,
- wherein the spring connector plate has a first face directed toward the carriage and a second face axially opposite the first face and directed toward the frame second end, and the spring slots are open to the first and second faces of the spring connector plate, and
- wherein the spring second end of each spring has a neck portion slidable downwardly into a respective spring slot and a head portion larger than the neck and the respective spring slot for bearing against the second face of the spring connector plate when the neck portion is in the respective spring slot to axially fix the spring second end relative to the spring connector plate.
