Abstract
The spa rowing adapter is a device for installation within an existing pool or spa that transforms the pool or spa into a rowing machine. The user grips lever arms, pulling on the arms from a seated or standing position in a rowing motion. In contrast to the prior art, the spa rowing adapter uses a resistance cylinder rather than floppy resistance bands or bungee cords. The resistance cylinder provides an adjustable amount of resistance during both the extending and retracting motions. The resistance cylinder changes length in response to a force, with the resistance of the motion set by an internal mechanism. The internal mechanism is adjustable by the user through rotation of a collar.
Claims18
A spa rowing adapter that converts a pool into a rowing machine, the spa rowing adapter attaching to a pool wall, the spa rowing adapter using a resistance cylinder and not elastic bands or bungee cords, the spa rowing adapter comprising:
- a lever arm with a first arm end and a second arm end;
- the first end affixed at a pivot to the pool wall;
- the second end adapted to be gripped by a user;
- a resistance cylinder with a first cylinder end and a second cylinder end;
- the first cylinder end affixed at a pivot to the pool wall;
- the second cylinder end affixed at a clamping collar to the lever arm;
- the resistance cylinder able to extend and retract in length;
- the resistance cylinder creating a force in opposition to an extension in length;
- and
- whereby motion of the lever arm causes the resistance cylinder to extend and retract in length, creating resistance and thus permitting the user to exercise.
A spa rowing adapter that permits adjustment of the resistance without requiring any replacement of parts, the spa rowing adapter for installation of a spa that has a water level, the spa rowing adapter comprising:
- a lever arm that rotates about a first pivot, the first pivot affixed to the spa above the water level;
- an adjustable resistance cylinder that rotates about a second pivot, the second pivot affixed to the spa above the water level;
- the adjustable resistance cylinder affixed to the lever arm;
- the motion of the lever arm altering the length of the adjustable resistance cylinder;
- the adjustable resistance cylinder generating a force in opposition to the motion of the lever arm;
- the force being adjustable;
- whereby the lever arm is adapted for movement by a user, the user moving the lever arm in a rowing motion and thus exercising within a pool.
A pool accessory that creates a rowing machine in association with a pool, the device for installation above a water level of the pool to avoid the resistance of the water during use, the pool accessory comprising:
- a pair of lever arms in a pivoting relationship with the pool;
- the lever arms, after installation, are substantially parallel to the water level;
- a pair of resistance cylinders, each resistance cylinder of the pair of resistance cylinders in a rotating relationship with a lever arm of the pair of lever arms;
- whereby motion of the lever arms causes a change in length of the resistance cylinders, thereby resisting the motion of the lever arms, and thus permitting exercise.
