Abstract
A control component with a "D" shaped shaft is to be fitted with a control knob that was designed to fit onto a "dog-bone" shaped shaft. A resilient adapter in the form of a tubular sleeve has a special bore to fit on the shaft and a special configuration to fit into the bore of the knob so as to prevent relative rotational movement therebetween.
Claims5
A resilient adapter used for fastening a knob to a shaft, said knob having a bore for receiving a "dog-bone" shaped shaft and the shaft being of generally "D" shaped cross-section, said adapter comprising a tubular sleeve with a "D" shaped bore and a circular periphery having a longitudinal depression adjacent the flat side of the bore, the bore of the sleeve being slightly oversized and the circular periphery of the sleeve being slightly undersized, and internal and external longitudinal ridges formed on the sleeve and adapted to create a force-fit between the "D" shaped shaft and the adapter as well as between the adapter and the bore of the knob.
