Safety control system for motorized resistance equipment utilizing one-way clutches
A safety control system for use with an exercise apparatus utilizing a one-way clutch includes a rope wrapped around a spindle driven by a motor. A controller is capable of applying a brake when power loss is detected by an internal circuit to ensure the safety of the apparatus and user.
1. A safety control system for exercise equipment having a flexible element wound about a spindle driven by a motor, the system comprising:
a circuit for detecting a power loss and for monitoring a motor speed;
a brake; and
a controller capable of applying said brake when a power loss is detected whereby the brake applies a graduated torque based upon said monitored speed to control a payout of said flexible element wherein said graduated torque is zero when said speed is above a threshold value and said graduated torque graduates to full as said speed declines to a zero value.
2. The system as defined in claim 1 wherein said brake is said motor.
3. The system as defined in claim 1 wherein said brake is an external brake.
4. The system as defined in claim 1 wherein said controller has a back-up power supply.
