摘要： A dry shaver has a readily replaceable head frame supporting an outer shearing foil. The head frame is of a generally rectangular configuration with a pair of opposed end walls between which an inner cutter assembly projects from a shaver housing for shearing engagement with the undersurface of the shearing foil. Each of the end wall is integrally formed with a hook for locked engagement with a corresponding stop on the part of the housing to retain the head frame on the top of the housing. Also formed integrally on each of the end walls is a release lever which is capable of resiliently flexing in a direction of disengaging the adjacent hook form the stop, permitting the removal of the head frame. With the provision of forming the release lever on the head frame together with the hook, the removable of the head frame can be made simply by pressing the release levers while holding the head frame itself by the same fingers of the user, greatly enhancing the convenience of replacing the head frame together with the shearing foil.

摘要： A vibratory linear actuator employs a reciprocating type motor for reciprocatingly driving several movable components at the same frequency and in opposite phase relations with each other. Both movable components are mechanically connected so as to transmit vibration from one to the other by reversing the direction of the vibration thereof. By this arrangement, the opposite phase relation between both movable components is mechanically insured. As a result, since the opposite phase relation between movable components can be maintained even when an external disturbance is applied thereto, the whole vibration system is stable against external disturbances.

摘要： A dry shaver comprises a head frame mounting at least one cutter head. The cutter head includes a holder carrying an outer foil and an inner cutter which is driven to move in shearing contact with the outer foil. A spring is provided to give a biasing force to bias the inner cutter against the outer foil so as to develop a contacting pressure therebetween. The shaver includes a floating support structure for floatingly supporting the holder to the head frame so that the cutter head can be depressed relative to the head frame. The floating support structure comprises an elastic member which gives an elastic force when the cutter head is displaced relative to the head frame such that cutter head receives a floating force which is a combination of the biasing force and the elastic force and which becomes greater as the cutter head is depressed further. The elastic member develops the elastic force which gives a non-linear relation between the displacement of the cutter head and a depression load applied thereto, and that the non-linear relation has a node of changing elastic constant for displacement of the holder such that the elastic constant is greater when the cutter head is depressed further beyond the node than otherwise. Since the elastic member is only responsible for changing the elastic constant as the cutter head is depressed, the cutter head can be given a light floating force initially and be given an moderately increasing floating force thereafter, yet without resorting to an undue increase in the contacting pressure between the outer foil and the inner cutter.

摘要： A depilating device has a housing with a top opening and a plucking head with a longitudinal axis. The plucking head carries a series of pinching elements arranged in side-by-side relations to form therebetween gaps. At least one of the adjacent pinching elements is movable relative to the other so as to entrap and pinch the hairs between the adjacent pinching elements for plucking the hairs from the skin. A skin guide is disposed around the plucking head to be exposed at least partially beyond the pinching elements for sliding contact with the skin. The plucking head and the skin guide are floatingly supported to the housing by means of a common structure such that they are depressed together into the housing within a predetermined extent.

摘要： A depilating device removes hairs from the skin of a user and includes a carrier mounting a series of fixed and movable pinching plates arranged along an axial direction of the carrier in an alternating relation and in a closely adjacent relation to form small clearances between the adjacent movable and fixed pinching plates for entrapping hairs therebetween. The fixed pinching plates are kept fixed with respect to the axial direction of the carrier. The movable pinching plates are caused to be displaced in the axial direction relative to the adjacent fixed pinching plates in order to repeat clamping the hairs between the adjacent ones of the fixed and movable pinching plates and releasing the same, thereby plunking the hairs from the skin. The depilating device is characterized in that the fixed and movable pinching plates are arranged and displaced such that the two adjacent ones of the movable pinching plates are caused to shift in the opposite directions along the axis of the carrier against the common fixed pinching plates positioned between these two adjacent movable pinching plates to thereby apply counterbalancing clamping forces to the common one of the fixed pinching plates from the two adjacent movable pinching plates.

摘要： A dry shaver with a skin stretcher comprises a shaver body and a shaving head mounted on top of the shaver body. The shaving head comprises at least one cutter unit with a perforated outer cutter. An inner cutter is driven to move in hair shearing engagement with the outer cutter. The skin stretcher comprises a skin contact elongated along the periphery of the outer cutter and a base through which the skin contact is held on the shaving head. A macro displacement structure is provided to allow the skin contact to be movable within a macro displacement range relative to the shaver body. The skin contact is made from an elastic material capable of being elastically deformed within a micro displacement range relative to the base. With the combination of the macro and micro displacements of the skin contact, the skin contact can be kept in contact with the skin of a user in conformity with various contours of the skin. Thus, the skin stretcher can stretch a large portion of the skin even with an uneven skin surface, i.e., around the chin or the like to raise the hairs over a wide area prior to the shaving by the cutter unit, thereby assuring smooth and effective hair shaving at the cutter unit.

摘要： A reciprocatory dry shaver has a head from mounting three elongated cutter heads, one center cutter head and two outer cutter heads extending in parallel with each other. Each cutter head comprises a holder carrying a stationary cutter and a movable cutter driven to reciprocate in shearing engagement with the stationary cutter. The head frame is mounted on a shaver housing from which a reciprocating element projects to drive the movable cutter of each cutter head. The center and outer cutter heads are floatingly supported at individual longitudinal ends by associated center and outer spring members so that each cutter head is vertically movable relative to the head frame. The center spring members are formed in one of the head frame and the associated holder while the outer spring members are formed in the other of the head frame and the associated holders. Thus, the spring members for floatingly supporting the center and outer cutter heads can be effectively distributed to the head frame and the associated holders to enable compact arrangement for a system of floating supporting the three parallel cutter heads within a limited space.

摘要： A reciprocatory cutter head includes a pair of cutter heads mounted to a head frame. Each of the cutter heads is of elongated configuration extending horizontally to define a longitudinal axis and have opposed longitudinal ends. The cutter head includes an elongated outer shearing foil which comes into hair shearing engagement with an inner cutter driven to reciprocate along the longitudinal axis. The cutter heads are floatingly supported to the head frame in such a manner that the cutter heads are vertically movable relative to the head frame independently from each other as well as that each of the cutter heads is vertically movable at one longitudinal end substantially independently of the other longitudinal end. Whereby, the cutter heads cooperate with each other to readily conform to the shapes of a user's skin with maximum skin engaging area for assuring enhanced shaving performance, particularly at the irregularly contoured portions of the skin.
