Abstract
A shaver includes a housing including first and second housing halves defining an interior chamber, the housing having an operational end and an opposite, bottom end, the interior chamber containing a motor acting through a transmission and configured for reciprocally driving a pair of laterally reciprocating drive fingers. Each drive finger includes an elongate finger drive element extending from the operational end. A resilient seal having slits accommodating the finger drive elements is captured in corresponding seal cavities in each of the housing halves. The seal and the housing halves are configured for placing the seal in at least one of radial and axial compression upon assembly of the housing halves together.
Claims17
A shaver, comprising:
- a housing including first and second housing halves defining an interior chamber, said housing having an operational end and an opposite, bottom end;
- said interior chamber containing a motor acting through a transmission and configured for reciprocally driving a pair of laterally reciprocating drive fingers, each said finger including an elongate finger drive element extending from said operational end;
- a resilient seal including slits accommodating said finger drive elements and being captured in corresponding complementary seal cavities in each of said housing halves;
- said housing halves each have an inclined basket engagement rib constructed and arranged so that as said housing halves are joined, increasing compressive force is exerted on said seal for placing the seal in at least radial compression so that said seal is held in place by said at least radial compression upon assembly of the housing halves together;
- and
- said pair of drive fingers includes a short drive finger and a long drive finger, each said finger having a foot including at least one integrally formed spring element having an attachment end, each said attachment end being secured in at least one of said housing halves, and each said finger directly engaging a moving blade.

- said seal and said housing halves are configured for placing the seal in at least one of radial and axial compression so that said seal is held in place by said compression upon assembly of the housing halves together;
- a shaver head releasably attachable to said operational end of said housing, said shaver head including a shaver head body with a pair of perforated shaver foil cartridges releasably secured thereto;
- said shaver head body has opposed ends defining a pair of cartridge tracks, and each said foil cartridge has a pair of spring clips, each said clip constructed and arranged for releasably engaging a corresponding one of said tracks;
- and
- each said spring clip has a dogleg free end, and each said track has a landing for releasably receiving said clip in an operational position, and such that user pressure on said cartridge towards said housing releases engagement between said dogleg free end and said landing for releasing said cartridge from said shaver head body.
