Abstract
Proposed is a muscle exercise device. In the muscle exercise device, when it is detected that a withdrawal position of a cable has entered a preset safety area in a process in which a device control part controls a drive motor in an exercise mode, the drive motor may be controlled so that an exercise load of the drive motor is reduced. Through this, when it is detected that the cable is retracted into the safety area without completely entering the initial position, for example, the device body, an exercise load may be reduced, thereby obtaining the same effect as ending exercise by mounting an exercise device such as a barbell to an existing mounting part.
Claims20
A muscle exercise device comprising:
- a device body;
- at least one drive motor installed inside the device body and configured to provide an exercise load;
- a cable configured to be pulled out of the device body to transfer the exercise load of the drive motor outside of the device body;
- a sensor configured to detect a withdrawal position of the cable;
- and
- a controller configured to control the drive motor so that the exercise load of the drive motor is reduced when the sensor detects that the withdrawal position of the cable has entered a safety range.
An apparatus comprising:
- a body;
- a motor provided inside the device body and configured to provide a load;
- a cable coupled to the motor and configured to be pulled out of the body to transfer the load of the motor outside;
- a sensor configured to detect a withdrawal length of the cable;
- and
- a controller configured to control the motor,
- wherein the controller controls the motor so the load of the motor is a first load when the withdrawal length of the cable is within an exercise range, and the load of the motor is a second load that is less than the first load when the withdrawal length of the cable is within a safety range.
An apparatus comprising:
- a motor;
- a bar coupled by a cable coupled to the motor, the bar being moved by a user during an exercise;
- a sensor that detects a movement of the cable;
- and
- a controller that determines when a user is performing an exercise based on the movement of the cable,
- wherein the controller controls the motor to sequentially provide a first load before the user performs the exercise, provide a second load greater than the first load while the user performs the exercise, and a third load less than the second load after the user performs the exercise.
