Abstract
A jogging apparatus 22 has motor 24 mounted within a support frame 20. Motor 24 has a motor shaft 28 to which is connected hub 30. Projecting outwardly from motor hub 30 along an axis parallel to, but eccentrically offset from, the axis of motor shaft 28 is eccentric pin 34. Slotted link 32 slidably engages slot pins 36 and 38 in transverse slots 42 and 44 respectively of slotted link 32 for transverse movement of slotted link 32. Slotted link 32 also has an orthogonal slot 46 generally perpendicular to transverse slots 42 and 44. Eccentric pin 34 is slidably engaged within orthogonal slot 46 such that as motor shaft 28 is rotated, the rotational motion of shaft 28 is converted into the side-to-side motion of slotted link 32. Eccentric pin 34 projects somewhat beyond the outer surface of slotted link 32 and typically terminates in enlarged head 57. Enlarged head 57, with respect to orthogonal slot 46, describes an up and down movement within slot 46, as motor shaft 28 rotates. To a lower portion of slotted link 32 is attached by pin 58 and bracket 63 a shoe link 56 from which depends a jogging shoe 62. Shoe link 56 has projecting upwardly therefrom, and partly overlapping slot 46, …
