Abstract:
1. A leg elevator comprising: a base having a lower leg end and an upper leg end; a lower leg support; a height adjustment mechanism between said lower leg end of said base and said lower leg support for adjusting a height of said lower leg support above said base; an upper leg adjustment mechanism operably connected to said upper leg end of said base for adjusting a distance between said upper leg end of said base and said lower leg support, said upper leg adjustment mechanism comprising a telescopic leg having a first substantially hollow section having a first end and a second end, a second substantially hollow section having a first end and a second end, said second end of said second substantially hollow section defining an opening to telescopically receive said second end of said first substantially hollow section, and a means for retaining said first substantially hollow section telescopically in a desired position relative to said second substantially hollow section; an upper leg platform supported by said upper leg adjustment mechanism; and an angle adjustment mechanism between said upper leg adjustment mechanism and said lower leg support for adjusting a relative angular orientation of said upper leg platform relative to said lower leg support, said angle adjustment mechanism having a ball-ratchet mechanism providing a releasable fixed resistance at a variable angle for adjusting said relative angular orientation of said upper leg platform relative to said lower leg support frame, said ball-ratchet mechanism having an elongated threaded connector.
