Crank for exercise equipment which helps prevent injuries on a rider's ankle during an unexpected drop in speed and assists in avoiding stress on the knees of a rider during exercising

摘要

An exercise equipment with an improved connecting bar connecting an exercise foot retaining device to a resistance, wherein a first longitudinal pedal bar is connected to a first bent longitudinal pedal connector bar and a second longitudinal pedal bar is connected to a second bent longitudinal pedal connector bar, the first and second bent longitudinal connector bars each having a bent angle greater than zero and less than ninety degrees to thereby prevent the occurrence of a dead angle.

主权项

1. An elliptical trainer having a right rotatable elliptical handlebar and a left rotatable elliptical handlebar, a right longitudinal pedal bar to which a right foot plate is attached, the right longitudinal pedal bar rotatably connected at a first end to the right rotatable elliptical handlebar, a left longitudinal pedal bar to which a left foot plate is attached, the left longitudinal pedal bar rotatably connected at a first end to the left rotatable elliptical handlebar, a body having a resistance wheel for generation of power, said elliptical trainer comprising:
a. said body affixed to a non-moving base; b. a right bent pedal connector bar having an exterior end, a middle bent section, and an interior end, the exterior end of the right bent pedal connector bar rotatably connected to a second end of the right longitudinal pedal bar, the right longitudinal pedal bar configured to translate in a reciprocal fashion while the right bent pedal connector bar rotates in a vertical plane; a left bent pedal connector bar having an exterior end, a middle bent section, and an interior end, the exterior end of the left bent pedal connector bar rotatably connected to a second end of the left longitudinal pedal bar, the left longitudinal pedal bar configured to translate in a reciprocal fashion while the left bent pedal connector bar rotates in the vertical plane; c. the right bent pedal connector bar and the left bent pedal connector bar respectively connected at their respective interior ends to respective ends of a connecting rod, the connecting rod affixed to a connecting member which in turn is affixed to the resistance wheel, the exterior end of the right bent pedal connector bar configured to move in a first direction toward the right rotatable elliptical handlebar when the left bent pedal connector bar is rotated in a direction away from the left rotatable elliptical handlebar; d. said right bent pedal connector bar having a body formed of said exterior end, middle bent section, and interior end, with an imaginary straight line between said exterior end and said interior end of said right bent pedal connector bar, at least a portion of said imaginary straight line exterior to the body of the right bent pedal connector bar resulting in the middle bent section of the right bent pedal connector bar being configured to avoid a dead angle between the right bent pedal connector bar and the right longitudinal pedal bar; and e. said left bent pedal connector bar having a body formed of said exterior end, middle bent section, and interior end, with an imaginary straight line between said exterior end and said interior end of said left bent pedal connector bar, at least a portion of said left bent pedal connector bar having an imaginary straight line exterior to the body of the left bent pedal connector bar resulting in the middle bent section of the left bent pedal connector bar configured to avoid a dead angle between the left bent pedal connector bar and the left longitudinal pedal bar.
