Abstract

一种安全剃刀的刀片装置，它包括一护罩、一罩盖以及由三个刀片构成的刀片组，上述三个刀片具有相平行的锐利刀刃，这些刀刃位于所说的护罩与罩盖之间，限定离护罩最近刀刃的第一刀片具有不大于零的露出量，而限定离罩盖最近刀刃的第三刀片则具有不小于零的露出量。

Description

安全剃刀的刀片装置
本发明涉及到安全剃刀，具体地说，本发明涉及到带有刀片装置的安全剃刀，所说的刀片装置则带有多个刀片，这些刀片限定了相互平行的设置成能依次在所剃须的皮肤表面上经过的锐利刀刃。正如在本技术中所周知的那样，刀片装置可永久地与剃刀手柄相连或者是一种在刀刃变钝时可以更换的拆卸式刀片盒。在上述两种类型的剃刀中，刀片装置可以固定在手柄的适当位置上或者可绕平行于刀刃的轴作枢轴运动。本文所公开的发明适用于刀片装置的所有上述形式。
带有双刀片式刀片装置的安全剃刀近年来已大量地售出，并且，特别是就细密性而言，一般都公认这种安全剃刀有比单刀片式剃刀更高的剃须质量。国际申请WO 92/17322公开了一种三刀片剃刀架，其两个刀片有普通的锐边，第三刀片位于第一刀片后面，并有一没有锐边的较纯的边缘，足以陷进面部毛发或括擦皮肤。此外，近年来已有许多书面申请提出了带多个刀片的安全剃刀。带有多个刀片的刀片装置要比只带有一个或两个刀片的类似刀片装置有更细密的剃须效果。但是，剃须的细密性只是剃刀使用者判断剃刀效率的一个参数。增加额外的刀片会对刀片装置的其它特征产生不利的影响，最明显的是对刀片装置在皮肤上移动时的阻力特征产生不利影响。因此，尽管可以获得较为细密的剃须效果。但刀片装置的整体效率会显著地下降。结果，据我们所知，到目前为止带有含两个以上刀片的刀片装置的剃刀尚未成功地进入市场。
本发明的目的是提供一种包括有三个刀片的刀片装置，通过按特定的几何布局来相对位于刀刃前面和后面的护罩及罩帽表面彼此设置刀片，可以将摩擦阻力保持在可接受的水平，同时还可提高剃须效率。
本发明提供了一种安全剃刀的刀片装置，它包括一护罩，一罩盖以及由三个刀片构成的刀片组，上述三个刀片具有相平行的锐利刀刃，这些刀刃位于所说的护罩与罩盖之间，其特征在于：形成离护罩最近刀刃的第一刀片的露出量为负值并且不小于-0.2mm，而形成离罩盖最近刀刃的第三刀片的露出量为正值并不大于+0.2mm，上述第二刀片的露出量不小于第一刀片的露出量且不大于第三刀片的露出量。
就带有按本文所述方式设置的刀片的三刀片安全剃刀刀片装置而言，我们发现，与两刀片安全剃刀相比，它能提高整个的剃须效率。
以下参照附图说明本发明的特定实施例，附图中：
图1显示了本发明示例性实施例的横断面的概略图；以及
图2显示了本发明最佳实施例的横断面的概略图。
图1和图2中说明了要安装在剃刀手柄上的安全剃刀刀片装置。该刀片装置可永久性地与诸如一次性剃刀的手段相连，或者将该刀片装置形成为一刀片盒，此刀片盒能以可拆卸的方式安装在剃刀手柄上。在以上两种情况中，手柄不是本发明的组成部分，所以，不对手柄作进一步的说明。
上述刀片装置带有一底座1，它限定了一护罩2以及一罩盖3。如图所示，罩盖包括一安装在底座上的润滑条4。该润滑条具有本技术中周知的形状。底座承载着具有平行锐利刀刃的第一、第二和第三刀片11，12，13。底座稳固地支承着上述刀片，因而，这些刀片可基本上固定在所示(即刀片因剃须过程中施加给它们的力而产生弹性变形)的位置处。另外，也可以将上述刀片支承成能逆着弹簧的恢复力例如沿图中向下的方向作有限的运动。上述刀片装置的基本结构和组合方式都是常规性的，本发明的新颖方面在于提供了三个刀片，这三个刀片按彼此之间以及相对防护罩和罩盖的特定位置设置在刀片装置内。
在图1的刀片装置中，上述三个刀片的刀刃均处于同一平面P内，该平面还与护罩以及罩盖的皮肤接触表面相切，因而，该平面构成了作为测定刀片露出量基准的“露出量平面”。事实上，对三个刀片11、12、13中的每一个刀片来说，所说的露出量均等于零。第一刀片11的跨度S1在0.5至1.5mm之间并且最好基本上等于0.70mm。第二刀片12的跨度S2和第三刀片13的跨度S3具有在1.0至2.0mm范围内的值。上述两个跨度如图所示具有基本上等于1.50mm的值。第三刀片的刀刃在罩盖前方位于距离S4处，距离S4基本上等于1.80mm。在第一刀片具有零露出量且第三刀片也具有零露出量的情况下，所述实施例显示了这样一种结构，在该结构中，前述两个刀片的露出量在本发明所提出的范围内。尽管如此，从按着包括所有剃须特征在内的可令人接受的剃须细密性角度说，上述刀片装置会产生非常好的剃须效果。
如图1所示，前述三个刀片具有同样的剃须角度A，但这并不是必须的。图2显示了一种更佳的结构。跨度S1、S2、S3和S4与图1中所说的跨度相同。本实施例中的第一刀片具有-0.04mm的露出量，第二刀片12的露出量为零，所有三个刀片的刀刃同在图1中一样处于同一平面P内，第三刀片13的露出量为+0.06mm。这样，刀片的露出量从前面的刀片11到后面的刀片13是逐渐增加的。
就本发明的实施例而言，通过选定刀片的露出量可以减小刀片装置在使用过程中所经受的与刀片有关的阻力，同时，由于存在有三个锐利的刀片，所以能可靠地提高剃须效率。
