| 摘要 |
This invention relates to devices that prevent brake cables (128A, 128B) from twisting when in use on a barbell. Previously, weight training equipment did not have brakes, so brake cable twisting was not a known problem. However, embodiments of the present invention use a cross bar (130) mechanically coupled to a barbell (110) that is further mechanically coupled to a first brake (116) such that the barbell can rotate to but not through the first brake, enabling a range of motion of approximately 300 degrees. Further, a gyroscope (140) mechanically coupled to the brake cables rotates with the brake cables and prevents the brake cables from twisting. |
