Reciprocatory dry shaver

Abstract

A reciprocatory dry shaver is capable of providing a drive point of transmitting a reciprocating force to an inner cutter from a drive element at a location as close as to a cutting edge of the inner cutter for enhancing cutting performance, yet making the use of a plastic made drive element to give a detachable connection with the inner cutter. The shaver comprises a housing incorporating a drive source which is connected to move a drive element projecting on top of the housing. An outer cutter is supported to the top of the housing. An inner cutter is detachably connected to the drive element and is driven thereby to reciprocate in hair shearing engagement with the outer cutter. The drive element comprises a stud and a pin which projects beyond the upper end of the stud. The inner cutter is formed with a joint for detachable connection to the stud and with a catch for detachable connection to the pin. The catch is formed upwardly of the joint to define a drive point at the connection with the pin where the drive element transmits a driving force of reciprocating the inner cutter. With this arrangement, the driving point can be disposed closer to an upper cutting edge of the inner cutter than a connection point of detachably holding the inner cutter to the drive element. Consequently, a driving force is effectively applied for hair shaving between the reciprocating inner cutter and the outer cuter, thereby enhancing cutting performance.
