Abstract
The exercise machine with a variable resistance system includes a frame, an exercise implement movably connected to the frame, a main shaft rotatably connected to the frame, a main connector attached between the main shaft and the exercise implement, a plurality of resistance assemblies and a plurality of actuation assemblies adapted for selectively engaging or disengaging at least one of the plurality of resistance assemblies with respect to the main shaft. The plurality of resistance assemblies apply a total level of rotational resistance against the main shaft based on which of the plurality of resistance assemblies are engaged with the main shaft by the plurality of actuation assemblies.
Claims17
An exercise machine with variable resistance system, comprising:
- a frame;
- an exercise implement movably connected to said frame;
- a main shaft rotatably connected to said frame;
- a main connector attached between said main shaft and said exercise implement;
- a plurality of resistance assemblies, wherein each of said plurality of resistance assemblies includes a bias member adapted to exert a resistance force against rotation of said main shaft in a first rotational direction, wherein each of said plurality of resistance assemblies is selectively rotationally locked with said main shaft or rotationally unlocked with said main shaft;
- and a plurality of actuation assemblies, wherein each of said plurality of actuation assemblies are adapted for selectively rotationally locking and unlocking at least one of said plurality of resistance assemblies with respect to said main shaft, wherein said plurality of resistance assemblies apply a total level of rotational resistance against said main shaft based on which of said plurality of resistance assemblies are rotationally locked with said main shaft by said plurality of actuation assemblies;
- wherein each of said plurality of resistance assemblies includes a clutch;
- wherein each of said plurality of actuation assemblies includes a shift member having pivoting or sliding motion longitudinally along the main shaft to connect to said clutch for engaging or disengaging said clutch to selectively rotationally lock or unlock each of said plurality of resistance assemblies with respect to said main shaft.
An exercise machine with variable resistance system, comprising:
- a frame;
- an exercise implement movably connected to said frame, wherein said exercise implement is comprised of a carriage movable between a first end of said frame and a second end of said frame;
- a main shaft rotatably connected to said frame;
- a main connector attached between said main shaft and said exercise implement;
- a plurality of resistance assemblies, wherein each of said plurality of resistance assemblies includes a bias member adapted to exert a resistance force against rotation of said main shaft in a first rotational direction, wherein each of said plurality of resistance assemblies is selectively rotationally locked with said main shaft or rotationally unlocked with said main shaft;
- and a plurality of actuation assemblies, wherein each of said plurality of actuation assemblies are adapted for selectively rotationally locking and unlocking at least one of said plurality of resistance assemblies with respect to said main shaft, wherein said plurality of resistance assemblies apply a total level of rotational resistance against said main shaft based on which of said plurality of resistance assemblies are rotationally locked with said main shaft by said plurality of actuation assemblies;
- wherein each of said plurality of resistance assemblies includes a clutch;
- wherein each of said plurality of actuation assemblies includes a shift member having pivoting or sliding motion longitudinally along the main shaft to connect to said clutch for engaging or disengaging said clutch to selectively rotationally lock or unlock each of said plurality of resistance assemblies with respect to said main shaft, wherein said clutch is engaged or disengaged by one of said plurality of actuation assemblies;
- wherein each of said plurality of resistance assemblies comprises a pulley rotatably positioned upon said main shaft and wherein said pulley is connected to said bias member, wherein said clutch selectively engages said pulley to selectively rotationally lock or unlock said pulley with respect to said main shaft.
