Accessory clamp for medical table

摘要

An improved clamp for releasably and adjustably securing accessories, such as hanger rods for parenteral solution containers, to medical tables. The clamp has a generally cylindrical body comprising two main sections arranged in axial alignment: a base section and a cup section. Annular rows of intermeshing teeth are provided along the opposing end faces of the respective sections to prevent relative rotation of those sections unless such movement is accompanied by slight axial separation. The cup section includes a chamber terminating in an enlarged end opening that rotatably receives the cylindrical shank of a first operating knob. The knob is threadedly supported upon a hollow stem which is joined at one end to the base section and which extends axially through the chamber of the cup section. A pair of generally triangular openings in the side wall of the cup section receive the rod of a suitable accessory to be supported by the clamp, and a thrust bearing is urged by the shank portion of the first operating knob into tight engagement with the rod to secure it in place. Within the chamber is a compression spring that holds the thrust bearing an engagement with the shank of the operating knob and simultaneously urges the teeth of the respective sections into intermeshing engagement. A second operating knob, disposed immediately adjacent the first knob, is carried by an operating shaft that extends through the hollow stem and continues through the base section to an axially-movable clamping shoe arranged for releasably securing the entire clamp to the channel track of a medical table.
