Abstract
The present disclosure provides an integrant drive member for converting oscillating to reciprocating motion in a hand-held implement of the type having an elongate housing with an axially oscillable cap and a longitudinally reciprocal unit. The drive member comprises a pair of coaxial sleeve sections connected by a pair of links. One sleeve section is oscillable conjointly with the cap and the other is reciprocal conjointly with the unit. The links are pivoted at points defined by thin flexible webs formed at generally diametrically opposed positions on contiguous surfaces of the sleeve sections. Upon conjoint oscillation of the cap and the one sleeve section, the links swivel on the webs around the pivot points between folded and erect positions and reciprocate the other sleeve section and unit conjointly between retracted and extended positions.
