Exercise machine
First Claim
1. An exercise machine comprising:
- a base;
a first support frame mounted to said base;
a flywheel unit mounted rotatably to said first support frame;
a crank wheel unit mounted rotatably to said first support frame;
a transmission belt trained on said flywheel unit and said crank wheel unit; and
a pressurizing wheel mechanism including;
a mounting seat mounted to said first support frame, and disposed proximate to said transmission belt;
an upper pressure wheel unit provided pivotally on said mounting seat, and having an upper pressure wheel biased to move in a first direction so as to press and tense an upper segment of said transmission belt that extends between said flywheel unit and said crank wheel unit;
a lower pressure wheel unit provided pivotally on said mounting seat, and having a lower pressure wheel biased to move in a second direction so as to press and tense a lower segment of said transmission belt that extends between said flywheel unit and said crank wheel unit below said upper segment;
an upper limiting member mounted to said mounting seat to limit movement of said upper pressure wheel unit in a direction opposite to said first direction; and
a lower limiting member mounted to said mounting seat to limit movement of said lower pressure wheel unit in a direction opposite to the second direction.

Abstract
An exercise machine includes: a flywheel mounted rotatably to a support frame; a crank wheel mounted rotatably to the support frame; a transmission belt trained on the flywheel and the crank wheel; and a pressurizing wheel mechanism including a mounting seat mounted to the support frame, upper and lower pressure wheel units provided pivotally on the mounting seat, and upper and lower limiting members mounted to the mounting seat. The upper and lower pressure wheel units respectively have upper and lower pressure wheels biased to move in first and second directions so as to press and tense upper and lower segments of the transmission belt that extend between the flywheel and the crank wheel. The upper and lower limiting members limit movement of the upper and lower pressure wheel units in directions opposite to the first and second directions, respectively.
