## Abstract

A tilting inversion exerciser includes a foot support attached to an extension of a table, a carrier attached to the extension, a spindle attached to the extension, and a foot retaining device includes a lever having an oblong hole for slidably engaging with the spindle, a stem slidably attached to the lever, a pin attached to the stem and slidably engaged in a curved channel of the carrier biased to engage with the carrier, and the lever is engageable with the pin for retaining the pin to the carrier and for preventing the pin from being disengaged from the carrier when the extension of the table is inverted to an up-side-down position, and for giving some security to the user while conducting the inversion exercises.

## Claims

### Claim 1

A tilting inversion exerciser comprising:
a supporting stand,
a table rotatably supported on said supporting stand with a pivot axle, and including an extension extended from said table, and including a foot support attached to said extension, and including a carrier attached to said extension, the carrier including a curved channel formed therein, and the carrier including a plurality of depressions formed therein and communicating with the curved channel of the carrier,
a spindle attached to the extension, and
a foot retaining device including:
a lever including an oblong hole formed in a first end portion of the lever for slidably engaging with the spindle and for allowing the lever to be pivoted relative to the carrier and the extension,
a foot anchor device attached to the lever and movable toward and away from the foot support of the extension when the lever is pivoted relative to the carrier and the extension,
a stem slidably attached to the lever, the stem including a first end portion,
a pin attached to the first end portion of the stem and slidably engaged in the curved channel of the carrier,
a spring biasing member coupled between the stem and the lever for biasing the pin to engage with any of the depressions of the carrier,
wherein the stem includes a slot formed therein, and said lever includes a pole attached to a second end portion of the lever and slidably engaged in the slot of the stem engaging with the pole for guiding the stem to move relative to the lever,
wherein said stem includes a rod attached to said stem, and said spring biasing member is coupled between the rod and the pole,
wherein said lever includes a groove formed therein for slidably engaging with the rod, and
when the extension of the table is inverted to an up-side-down position where the extension is located above the table, the lever is movable downwardly relative to the extension and the spindle and the pin with a sliding engagement between the pin and the oblong hole of the lever, and the lever is engageable with the pin for retaining the pin in any of the depressions of the carrier, and for preventing the pin from being disengaged from the depressions of the carrier.

### Claim 2 (depends on 1)

The tilting inversion exerciser as claimed in claim 1, wherein said foot retaining device includes an actuating member attached to the stem for forcing the stem to move relative to the lever.
