Abstract
Abstract A shaver includes a housing and a shaving head detachably secured to the housing. A modular cutting assembly is detachably mounted in the shaving head and includes a plurality of blades that are reciprocated within the head for cutting hair. The blades are joined together by pins and releasably secured to a mounting block. A biasing element secured between the mounting block and the blades biases the blades away from the mounting block to provide a floating connection. The mounting blade is slideably positioned on a clip that is resiliently positioned within the shaving head. The shaver also includes a modular clipper assembly including a pair of blades reciprocally mounted within the shaving head. A clipper guard is slideably mounted in the housing for movement toward and away from the clipper blades and includes at least one sloped slot and a cutout portion with an inclined edge including at least one detent. A guard adjustment member is slideably mounted on the shaving head and includes a guide pin that is mounted within the slot and a detent pin member positioned to engage the inclined edge of the cutout and the detent defined thereon to vary the position of the guard.
