ABSTRACT:
A lever attachment for a rotary door knob comprises an arcuate collar adapted to embrace the knob, the collar terminating at its opposite ends in arms and being formed on an arc such that the arms have a tendency to diverge. The collar is formed of material sufficiently resilient to enable the arms to be moved into engagement with one another, thereby causing radial contraction of the collar and enabling the latter to grip the knob. The arms are releasably maintained in engagement by any one of a number of different kinds of latches.
