Abstract
A fitness device comprises a force applicator comprising: a rope, a base; a first fixed wheel positioned under the rope; a second fixed wheel positioned under the rope, wherein the second fixed wheel is substantially in line with the first fixed wheel; and a movable wheel positioned above the rope and above and between the first fixed wheel and the second fixed wheel, the movable wheel comprising a movable center configured to move either toward, or away from, the first fixed wheel and the second fixed wheel, and is configured to allow rotation of the movable wheel about the movable center.
Claims15
A fitness device comprising:
- a closed circular rope having a bulge, and
- a force applicator comprising:
- a base;
- a first fixed wheel positioned under the closed circular rope and comprising a first center pivotally fixed to the base, the first center configured to allow rotation of the first fixed wheel about the first center;
- a second fixed wheel positioned under the closed circular rope and comprising a second center pivotally fixed to the base, the second center configured to allow rotation of the second fixed wheel about the second center, wherein the second fixed wheel is substantially in line with the first fixed wheel;
- a movable wheel positioned above the closed circular rope and above and between the first fixed wheel and the second fixed wheel, and comprising a movable center configured to move either toward or away from the first fixed wheel and the second fixed wheel, and is configured to allow rotation of the movable wheel about the movable center, wherein the movable wheel further comprises a screwed handle attached to the movable center and extends beyond the base;
- and
- a fixing element attached to the base and configured to fix the screwed handle to the base, and a nut configured to screw onto the screwed handle, and an elastic element placed between the nut and the fixing element,
- wherein the closed circular rope is positioned above the first fixed wheel and the second fixed wheel and under the movable wheel,
- wherein when the bulge encounters the moving wheel, the moving wheel is configured to move away from the first fixed wheel and the second fixed wheel over the bulge, thereby causing the screwed handle and the nut to move towards the fixing element and the elastic element to contract, and
- wherein after the bulge passes the first fixed wheel and the second fixed wheel and the movable wheel, the elastic element is configured to expand and pull the nut and the screwed handle away from the fixing element and move the movable wheel towards the closed circular rope,
- thereby allowing the bulge on the closed circular rope to pass between the movable wheel and the first fixed wheel and the second fixed wheel.

A force applicator for a fitness device having a closed circular rope having a bulge, the force applicator comprising:
- a base;
- a first fixed wheel comprising a first center pivotally fixed to the base configured to allow rotation of the first fixed wheel about the first center;
- a second fixed wheel comprising a second center pivotally fixed to the base configured to allow rotation of the second fixed wheel about the second center, wherein the second fixed wheel is substantially in line with the first fixed wheel;
- a movable wheel positioned above and between the first fixed wheel and the second fixed wheel, and comprising a movable center configured to move either toward or away from the first fixed wheel and the second fixed wheel, and is configured to allow rotation of the movable wheel about the movable center, wherein the movable wheel further comprises a screwed handle attached to the movable center and extends beyond the base;
- and
- a fixing element attached to the base and configured to fix the screwed handle to the base, and a nut configured to screw onto the screwed handle, and an elastic element placed between the nut and the fixing element,
- wherein the closed circular rope is configured to be accommodated in the force applicator, and wherein the closed circular rope is positioned above the first fixed wheel and the second fixed wheel and under the movable wheel,
- wherein when the bulge encounters the moving wheel, the moving wheel is configured to move away from the first fixed wheel and the second fixed wheel over the bulge, thereby causing the screwed handle and the nut to move towards the fixing element and the elastic element to contract, and
- wherein after the bulge passes the first fixed wheel and the second fixed wheel and the movable wheel, the elastic element is configured to expand and pull the nut and the screwed handle away from the fixing element and move the movable wheel towards the closed circular rope,
- thereby letting the bulge on the closed circular rope to pass between the movable wheel and the first fixed wheel and the second fixed wheel.
