Abstract:
1. An electric inversion table comprising: a base having a pivot hole at a top end thereof; a bench having a support seat disposed on a bottom surface thereof and a receiving surface which a user leans on at an inverted angle arranged at a top surface thereof; the support seat includes at least one pivot hole that is corresponding to the pivot hole of the base; a pivot shaft is passed through the pivot hole of the support seat of the bench and the pivot hole of the base so as to pivotally connect the bench and the base; thus the bench is able to rotate between a horizontal position and a vertical position relative to the base; a driving device that connects the bench to the base for driving the bench to rotate between the horizontal position and the vertical position relative to the base; the driving device having: wherein the clutch is driven to rotate by the gear through the pull member and the bench is rotated with the clutch by the projection of the clutch locked with the slot of the support seat of the bench; wherein the motor drives the gear and the clutch to rotate, and further drives the bench to rotate between the horizontal position and the vertical position when the projection of the clutch is mounted in the slot of the bench; wherein the bench is unable to be driven by the motor through the rotation of the gear and the clutch while the projection of the clutch and the slot of the bench are separated from each other; wherein the operation end of the pull member is able to be pulled outward by the user to drive the clutch moving outward, toward the gear when the bench is located at the vertical position and power failure occurs or the driving motor fails, causing the projection of the clutch and the slot of the support seat of the bench to separate from each other and the spring to compress, and at this moment the user can drive the bench to move from the vertical position to the horizontal position by body weight and then release the pull member; the projection of the clutch is locked into the slot of the support seat of the bench again by elastic recovery force of the spring.
