US Patent 10986943 Food shield pivot connection

A food shield pivot connection providing for adjustment of the angular orientation of a support arm, and any attached panel, relative to a food shield stand. A representative pivot connection includes a threaded shaft extending from the stand clamp, an opening extending through the panel support arm defining a pivot axis parallel to the lengthwise axis of the threaded shaft, and a plate positioned to selectively engage and disengage with the panel support arm. In this embodiment, a knob is threaded onto the threaded shaft, such that rotating the knob in a first direction drives the plate into engagement with the support arm, and rotating the pivot knob in the opposite direction allows a spring or similar mechanism positioned around the threaded shaft to bias the plate away from the support arm.
