摘要： An electric shaver is provided which can enhance the vibration sound by increasing the length of arch-like edges formed between adjacent slots of the inner blade. In the electric shaver, an inner blade having the arch-like edges is moved reciprocally while its outer face contacts with and slides over an inner face of an outer blade to cut beard. The inner blade has an arch-like plate member, as a main body of the inner blade, and it has slots extending from a side wall through a top curved portion to the other side wall, to form arch-like edges between adjacent slots, and the inner blade is connected through a joint to a driver of the main body to be moved reciprocally. Mounting members for the joint are provided at two ends of the inner blade in the longitudinal direction, and the lower ends of the edges at the central portion of the inner blade are set lower than the lower ends of the beads formed above the mounting members of the inner blade.

摘要： In a reciprocation type electric shaver having an outside blade unit detachable from a main body, the outside blade unit comprises a main blade, a slit blade and an outside blade holder for holding the main blade and the slit blade capable of floating up and down. A coupling structure for coupling the slit blade on the outside blade holder has a retaining structure for engaging the slit blade and the outside blade holder in a lateral direction of the outside blade unit so as to prevent disengagement of the slit blade from the outside blade holder when the slit blade is floated up and down with inclination. The retaining structure is a pair of fitting recesses formed on the slit blade and a pair of fitting protrusions formed on the outside blade holder.

摘要： A reciprocating electric shaver (1) is provided. This reciprocating electric shaver (1) includes a main body block (8) and a head block (10), the head block (10) having four rotary connecting portions (32) at the front and the rear positions on the upper left and the upper right ends, the main body block (8) having four head support members (37), each of which can move up and down independently, and head floating springs (44) biasing upward each of the head support members (37) for floating, each of the head support members (37) of the main body block (8) being connected at the upper ends with each of the four rotary connecting portions (32) in a manner such that the head block (10) can rotate back and forth about the transverse direction of the shaver, thus allowing the head block (10) to rock back and forth relative to the main body block (8). As a result, even when the head block (10) is pressed against a skin with a small force, the head block (10) can excellently rock back and forth to conform to the contour of the skin.

摘要： A reciprocatory dry shaver capable of driving an inner cutter smoothly along an arcuately curved outer cutter for efficient shaving. The dry shaver includes a shaving head carrying an outer cutter which is arcuately curved along its length, and an inner cutter driven to reciprocate along the length of the outer cutter. An actuator is mounted in the shaving head for driving the inner cutter. The actuator includes an oscillator which reciprocates in the lengthwise direction of the outer cutter and carries a joint for driving connection to the inner cutter. Also included in the actuator is a resilient coupling link which supports the oscillator to the shaving head in order to allow the oscillator to reciprocate relative to the shaving head. The resilient coupling link has its one end coupled to the oscillator and the other end anchored to the shaving head at a portion away from the inner cutter than the oscillator. Thus, the oscillator is supported as being floated or lifted with respect to the shaving head, thereby being allowed to travel along a path which is somewhat arcuate in coincidence with the arc of the outer cutter. Accordingly, the oscillator, i.e., the inner cutter carried thereon can be guided smoothly along the arc of the outer cutter, assuring smooth and efficient shaving.

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 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.
