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 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.
摘要翻译：干燥剃须刀包括安装至少一个刀头的头架。刀头包括承载外箔的保持器和与外箔剪切接触而被驱动移动的内刀片。提供弹簧以产生偏压力以将内刀片偏压抵靠外箔，从而在其间形成接触压力。剃须刀包括浮动支撑结构，用于将支架浮动地支撑到头部框架，使得刀头可相对于头部框架被压下。浮动支撑结构包括弹性构件，当刀头相对于头框移动时，弹性构件产生弹性力，使得刀头接收作为偏置力和弹力的组合的浮力，并且变得更大刀头进一步压下。弹性部件产生弹性力，该弹性力使切割头的位移和施加到其上的凹陷载荷之间呈非线性关系，并且非线性关系具有改变弹性常数的节点，用于使夹持器移位，使得当刀头被压下超过节点时，弹性常数大于否。由于弹性构件仅负责改变当刀头被压下时的弹性常数，所以刀头可以被初始地赋予轻的浮动力，并且此后将被给予适度增加的浮动力，而不会过度地增加接触外箔和内刀之间的压力。

摘要： A rotary dry shaver includes an outer shearing foil supported on a head frame and an inner cutter holder having a center axis and carrying a plurality of inner blades in hair shearing engagement with the outer shearing foil. The inner cutter holder is operatively connected to a rotary drive shaft of an electric motor so as to be driven thereby to rotate about the center axis. The outer shearing foil is held movable in the direction of the center axis relative to the head frame, while the inner cutter holder is movable along the center axis relative to the rotary drive shaft so as to be floatingly supported thereby. The dry shaver is characterized in that the outer shearing foil is connected to the inner cutter holder by means of a pin extending along the center axis such that the outer shearing foil and the inner cutter holder are movable together along the center axis relative to the head frame as well as the rotary drive shaft. Whereby contact pressure between the inner blades and the outer shearing foil can be kept substantially at a constant level irrespective of the relative movement of the outer shearing foil to the head frame.
摘要翻译：旋转式干式剃须刀包括支撑在头部框架上的外部剪切箔和具有中心轴线的内部切割器保持器，并且携带多个内部刀片以与外部剪切箔发生剪切接合。内切割器保持器可操作地连接到电动机的旋转驱动轴，从而被驱动从而围绕中心轴线旋转。外剪切箔可以相对于头框架沿着中心轴线的方向移动，而内切割器保持器可相对于旋转驱动轴沿着中心轴线移动，从而被浮动地支撑。干式剃须刀的特征在于，外剪切箔通过沿着中心轴延伸的销连接到内切割器保持器，使得外剪切箔和内切割器保持器可相对于头部沿中心轴线一起移动框架以及旋转驱动轴。由此内部叶片和外部剪切箔之间的接触压力可以保持基本上恒定的水平，而不管外部剪切箔与头部框架的相对运动如何。

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.
摘要翻译：具有皮肤担架的干燥剃须刀包括剃须刀主体和安装在剃须刀主体顶部上的剃须刀头。剃须刀头包括至少一个具有穿孔外刀片的刀具单元。驱动内部切割器以与外部切割器发生剪切接合。皮肤拉伸器包括沿着外刀片的周边细长的皮肤接触部以及皮肤接触件通过该基部保持在剃削头上的基部。提供宏观位移结构以允许皮肤接触在相对于剃须刀体的宏移位范围内可移动。皮肤接触由能够在相对于基部的微位移范围内弹性变形的弹性材料制成。通过皮肤接触的宏观和微位移的组合，皮肤接触可以保持与使用者的皮肤接触，以符合皮肤的各种轮廓。因此，即使在皮肤表面不均匀的情况下，即在下巴等附近，皮肤担架也可以拉伸大部分皮肤，以便在通过切割单元进行剃刮之前使毛发在较宽的区域上升高，从而确保平滑有效头发剃须在切割器单位。
