Patent ID: 7575541

Claim:
A spine stretch machine, comprising: a. a base frame; b. an inverting frame mounted in swivel connection to the base frame; c. a feet anchor on the inverting frame allowing the user to invert; d. an inversion motor that rotates a platform between a horizontal position and a vertical position around an axis via an inversion linkage connected to the inversion motor and a sliding bar; e. a back massaging portion having rollers for rolling the back of the user's body; and; f. a safety device comprising: i. a sliding rail formed on the base frame, wherein the inversion linkage is mechanically connected to the sliding rail and is at a first position on the sliding rail during normal operation; ii. a spring that when activated moves the inversion linkage relative to the base frame to restore the user back to horizontal position by sliding the inversion linkage from the first position on the sliding rail to a second position on the sliding rail so that the platform travels from the vertical position to the horizontal position; iii. wherein the sliding bar slides forward along the sliding rails together with a safety shock to bring the platform from vertically back to horizontally; wherein the inversion motor is mounted to the sliding rail at a rear position during normal operation, and wherein the inversion motor slides to a forward position when the safety device is activated.
