Abstract: A handle has an inner hub member which engages a shaft and rotates about a longitudinal axis therewith, an outer hub member which is disposed around the inner hub member and is coaxial therewith, and resilient material disposed in a space between the inner and outer hub members. The resilient material effects the transfer of rotational movement between the inner and outer hub members, and under normal operating conditions, the outer hub member is generally coaxial with the inner hub member and rotates in a tangential direction to effect the rotation of the inner hub member and the shaft. Thus, upon the rotation or movement of the outer hub member in a direction other than the tangential direction which results in the outer hub member extending along an axis angled to the longitudinal axis of the inner hub member, the inner hub member maintains its direction along the longitudinal axis by virtue of the resilient material disposed between the inner and outer hub members.

Abstract: The handle of the handle assembly can be detachably mounted in at least two different orientations relative to a defined apparatus axis. Furthermore, actuating elements of the particular instrument can be reached without difficulty via a suitable cutout in the handle without it being necessary for the operator to significantly change the manual hold on the handle. The handle assembly is especially advantageous on a surgical microscope.

Abstract: A valve safety handle having a handle slidably attached to a valve stem. The handle incorporates a handle female spline sized to engage a valve stem male spline. The handle female spline is urged out of engagement with the valve stem male spline by means of a spring trapped between the handle and valve stem. The valve stem also has a valve stem key sized to slide into a handle lower recess keyway. Thus the handle may engage with the valve stem only after the handle has been rotated relative to the valve stem until the valve stem key aligns with the handle lower recess keyway, and the handle has then been translated relative to the valve stem against the spring until the handle female spline is engaged with the valve stem male spline. An alternate embodiment incorporates an adapter having an adapter female spline sized to engage a standard plumbing valve stem male spline.
