Abstract

The tray has a horizontal base and an edge. A C-clamp has a horizontally oriented side coupled to a bottom surface of the base, normal to and adjacent the edge. The C-clamp has first and second vertically oriented sides extending downward. The second vertically oriented side has a threaded hole. A screw has a shaft, a handle at a first end, and a shoe at a second end of the shaft. The second end of the screw passes through the threaded hole of the second vertically oriented side of the C-clamp and extends horizontally toward the first vertically oriented side of the C-clamp. Moving the handle causes the second end of the screw to further extend horizontally toward the first vertically oriented side of the C-clamp such that the shoe and the first vertically oriented side of the C-clamp frictionally engage the support structure when positioned therebetween.
