Patent ID: 8485952

Claim:
A leg elevator comprising: a base having a lower leg end and an upper leg end, a portion of the base having a plurality of support retaining devices attached in corresponding locations on opposite sides of the base and positioned near the lower leg end of the base, each support retaining device having a plurality of peaks and at least one valley; a lower leg support; a height adjustment mechanism having a support leg pivotally attached at a first end to the lower leg support, the support leg having a second end attached to a support bar extending perpendicular to the support leg, the support bar being received within the valley and removably engaged with the at least one support retaining device such that a height of the lower leg support above the base may be adjusted; an upper leg adjustment mechanism operably connected to the upper leg end of the base for adjusting a distance between the upper leg end of the base and the lower leg support; an upper leg support operably attached to the upper leg adjustment mechanism; and an angle adjustment mechanism between the upper leg adjustment mechanism and the lower leg support, the angle adjustment mechanism having a ball-ratchet mechanism providing a releasable fixed resistance at a variable angle for adjusting a relative angular orientation of the upper leg support relative to the lower leg support.
