Swim stroke exercise device

A resistance mechanism for an exercise device having a support frame including a front end and a rear end, the mechanism comprising:

• at least one roller assembly attached to one of the front end of the support frame;
• a drive shaft connected to one end of the roller assembly;
• a first pulley disposed on the drive shaft;
• a spring rewind assembly disposed on the drive shaft and connected to the roller assembly;
• a resistance device adjustably mounted to the support frame above the roller assembly, the resistance device including an output shaft and a second pulley disposed on the output shaft;
• a resilient member operably connecting the first pulley and the second pulley;
• and
• a resistance adjustment mechanism spaced from and operably connected to the resistance device.

An exercise device for simulating a swimming motion, comprising:

• support structure including a body support arrangement for supporting the body of a user in a simulated swimming position;
• a pair of flexible elongated members adapted to be pulled to an extended position by a user to simulate a swim stroke;
• a shaft a biased retraction member having a spring rewind assembly mounted on the shaft and interconnected with each flexible elongated member for retracting the elongated member when the user ceases pulling on the flexible elongated member;
• a one-way clutch mechanism interposed between the shaft and each retraction member, wherein each one-way clutch mechanism functions to couple its respective retraction member to the shaft when the user pulls on the flexible elongated member and to decouple its respective retraction member from the shaft upon retraction of the flexible elongated member;
• and
• a resistance mechanism interconnected with the shaft for imparting resistance to the shaft and each retraction member when the retraction member is coupled to the shaft by the one-way clutch upon pulling of the flexible elongated member by the user.

An exercise device for simulating a swimming motion comprising:

• support structure including a body support arrangement for supporting the body of a user in a simulated swimming position;
• a pair of flexible elongated members, each of which defines a first and a second end, wherein the first end of each elongated member is adapted to be grasped by the user when in the simulated swimming position;
• and
• a resistance arrangement interconnected with the support structure, comprising a pair of rollers mounted on a drive shaft, wherein each roller is engaged with the second end of one of the elongated member;
• a biasing arrangement having a spring rewind assembly mounted on the drive shaft and interconnected with each roller for urging rotation of each roller in a first direction of rotation to coil each elongated member about its respective roller toward the second end of the elongated member;
• and
• a resistance device interconnected with each roller, wherein the first end of each elongated member is adapted to be pulled by the user when simulating a swim stroke to rotate its respective roller in a second direction of rotation to uncoil the elongated member from the roller, and where the resistance device imparts resistance to the roller upon rotation of the roller in the second direction of rotation to provide resistance to the user.
