Abstract

Disclosed are exercise equipment and a method for controlling the exercise equipment including a main body forming an external shape of the equipment, an extendable/retractable wire that is disposed inside the main body and exposed to the outside of the main body, a load generator that provides a set load when the wire is extended/retracted, a power supply that supplies power to the load generator, and a controller that controls the power supply and the load generator. The method includes an exercise load setting of setting the set load by determining the retraction of the wire while increasing a load generated by the load generator as the wire is extended, an exercise start determining of determining start of exercise based on the extension of the wire, an exercise load varying of reducing or increasing the load generated by the load generator based on a change in a length of the wire, and an exercise end determining of determining whether the exercise is in progress and whether the exercise is ended by sensing the length and the retracted state of the wire.

Claims (33)

1 . A method for controlling an exercise equipment including a main body forming an external shape of the exercise equipment, an extendable/retractable wire configured to be disposed inside the main body and exposed to the outside of the main body, a load generator configured to provide a set load when the wire is extended/retracted, a power supply configured to supply power to the load generator, and a controller configured to control the power supply and the load generator, the method comprising:

an exercise load setting step of setting the set load by determining the retraction of the wire while increasing a load generated by the load generator as the wire is extended;

an exercise start determining step of determining start of exercise based on the extension of the wire;

an exercise load varying step of reducing or increasing the load generated by the load generator based on a change in a length of the wire; and

an exercise end determining step of determining whether the exercise is in progress and whether the exercise is ended by sensing the length and the retracted state of the wire,

wherein an extended length of the wire is divided into a warm-up area, an exercise area, and an excessive exercise area based on an exercise range of a user, and

wherein the exercise load varying step of reducing or increasing the load generated by the load generator includes:

generating, by the load generator, a load smaller than the set load when the extended length of the wire is included in the warm-up area;

generating, by the load generator, the set load when the extended length of the wire is included in the exercise area; and

generating, by the load generator, a load greater than the set load when the extended length of the wire is included in the excessive exercise area.

2 . The method of claim 1 , wherein the exercise load setting step includes:

sensing the extension of the wire;

sensing stop of the extension of the wire;

increasing the load generated by the load generator;

sensing the retraction of the wire; and

setting the load of the load generator as the set load when the wire is retracted.

3 . The method of claim 2 , wherein the increasing of the load generated by the load generator includes increasing the load at a constant speed from a minimum load of the load generator.

4 . The method of claim 3 , wherein the sensing of the retraction of the wire is performed during the increasing of the load generated by the load generator.

5 . The method of claim 3 , wherein the sensing of the retraction of the wire includes reducing the load generated by the load generator to the minimum load when the retraction of the wire is sensed.

6 . The method of claim 2 , wherein the sensing of the extension of the wire includes sensing that the wire is extended by a length corresponding to an exercise area corresponding to an exercise range of a user.

7 . The method of claim 6 , wherein the sensing of the stop of the extension of the wire includes sensing that the extension of the wire is stopped for a predetermined period of time after the wire is extended by the length corresponding to the exercise area.

8 . The method of claim 3 , wherein the sensing of the retraction of the wire includes setting the load generated by the load generator when the retraction of the wire is sensed as the set load.

9 . The method of claim 1 , wherein the generating of the set load includes determining whether the extended length of the wire is included in the exercise area, and waiting while the wire is extended until the extended length of the wire is included in the exercise area.

10 . The method of claim 9 , wherein the exercise equipment further includes the load display including multiple LEDs arranged along an extension direction of the wire and configured to quantitatively display the set load thereon,

wherein the exercise equipment displays the change in the length of the wire based on the extension and the retraction of the wire in the exercise area on the load display in a manner of overlapping the set load displayed on the load display.

11 . The method of claim 10 , wherein the exercise equipment further includes the load display including multiple LEDs arranged along an extension direction of the wire and configured to quantitatively display the set load thereon,

wherein the exercise equipment displays the load generated by the load generator in the warm-up area on the load display in a manner of overlapping the set load displayed on the load display.

12 . The method of claim 1 , wherein the exercise equipment further includes a load display configured to quantitatively display the set load thereon, and the set load is displayed on the load display as being set.

13 . The method of claim 12 , wherein the load display includes multiple LEDs arranged along an extension direction of the wire, and the set load is displayed via sequential lighting of the LEDs.

14 . The method of claim 1 , wherein in the generating of the load greater than the set load, when it is determined that the extended length of the wire is included in the excessive exercise area, the load generated by the load generator has a magnitude within a range from 110 to 130% of the set load.

15 . The method of claim 14 , wherein a load generated by the load generator after the generating of the load greater than the set load is reduced in a magnitude to a magnitude within a range from 10 to 50% of the set load.

16 . The method of claim 1 , wherein the generating of the load smaller than the set load includes determining whether the extended length of the wire is included in the warm-up area and waiting until the extended length of the wire is included in the warm-up area.

17 . The method of claim 1 , wherein the load generated by the load generator has a magnitude within a range from 10 to 50% of the set load.
