Description

具有附加修剪刀片的剃须刀
技术领域
本发明涉及一种具有修剪刀片的剃须刀。
背景技术
近几年，具有各种数目刀片的剃须刀已在专利文献中提出并已被商业化，例如，如美国专利5,787,586中所述，该专利大体上描述了已由The Gillette Company作为三刀片的Mach III剃刀商业化的一型设计。
增加剃须刀上的刀片数量通常趋于提高剃刀的剃刮效率并提供更好的皮肤上的压力分布，然而它也可能趋于增大阻力、降低可操纵性并降低修剪例如鬓角或鼻侧的能力。引入本文以供参考的美国专利6,276,061描述了将安装在倾斜刀片支撑上的附加刀片设置在三刀片剃刀的后面以供修剪之用。该专利未描述如何将刀片固定到外壳上，以及显示它被连接到用于如图14所示的Mach III型剃刀的刀片架和手柄设计类型上。
发明内容
在一个方面，本发明的特征大体在于一种剃须刀，所述剃须刀包括具有在外壳正面的主防护件和在外壳背面的上表面处的主顶盖的外壳、在所述主防护件和所述主顶盖之间的一个或多个主剃须刀片、以及修剪刀片，所述修剪刀片安装在外壳背面并具有背离上表面定向的修剪刀片刀刃。剃刀也具有固定到外壳上的末端处具有弯曲的细长手柄，其中所述弯曲在与主刀片同一侧上呈凹形。
在另一个方面，本发明的特征大体在于一种剃须刀，所述剃须刀包括具有主防护件和主顶盖的外壳、在主防护件和主顶盖之间的一个或多个主剃须刀片、在外壳背面的具有背离上表面定向的刀刃的修剪刀片、以及具有指垫的细长手柄，所述指垫在手柄末端处在与主刀片同一侧上固定到外壳上。
在另一个方面，本发明的特征大体在于一种剃须刀，所述剃须刀包括具有主防护件和主顶盖的外壳、在主防护件和主顶盖之间的一个或多个主剃须刀片、在外壳背面的具有背离上表面定向的刀刃的修剪刀片、以及细长手柄，所述细长手柄在固定到外壳上的手柄末端处分成两部分，使得所述两部分之间存在一个区域。
本发明的特定实施方案可包括下列一个或多个特征。指垫可由弹性体材料制成。手柄可具有供接近指垫的松弛部分。可具有三个或四个或五个或更多个主刀片。外壳可通过一个接头绕轴转动地连接到手柄上，该接头具有一个静态止动位置以防止在修剪刀片剪切毛发时所述外壳绕枢轴转动。
本发明的实施方案可包括下列一个或多个优点。与主刀片在同一侧上的手柄中的弯曲、在同一侧上的指垫和由分叉的手柄提供的指垫接近口可在修剪鬓角或使用者皮肤上的其它腮须或毛发时，容许使用者将拇指或其它手指与修剪刀片齐平放置或放置在修剪刀片正下方，以便提供更大的精度和控制。

具体实施方式
参见图1和2，剃须10包括一次性刀片架12和手柄14。刀片架12包括连接到手柄14上的连接构件18和可绕轴转动地连接到连接构件18上的刀片单元16。刀片单元16包括塑料外壳20、在外壳20正面的主防护件22、在外壳20背面的具有润滑条26的顶盖24、在主防护件22和主顶盖24之间的五个细长刀片28、以及通过夹片32连接到外壳20后面的修剪刀片组合件30，所述夹片32还将刀片28保持在外壳20上。
参见图3，修剪刀片组合件30被固定到外壳20的背面并包括刀片载体502和安装在其上的修剪刀片504。刀片载体502由已被切割和成形的0.028cm(0.011″)厚的不锈钢金属片制成，以提供用于支撑修剪刀片504并因此限定修剪防护件和顶盖表面以及用于连接到外壳20上的结构。
参见图3至9，刀片载体502具有后壁506、在两个末端处从后壁506的顶部向前弯曲延伸的上突出部508、510、在后壁506的底部沿着后壁506的长度向前弯曲延伸的下壁512以及两个横向侧部514、516，每一个侧部均由在后壁506的末端从各自一侧向前弯曲延伸的侧向突出部518和从下壁512的各自末端向上弯曲延伸的竖直突出部520制成。
后壁506的中部在它的下部是开口的，以提供位于后壁506的下终端表面526和从下壁512向上延伸的修剪防护件528之间的间隙522。在终端表面526的两端，精确设置两个对齐表面530距终端表面526的底部的距离。修剪刀片504通过十三个点焊534焊接到后壁506的内表面532上，其中修剪刀片504的刀刃536与对齐表面530对齐。间隙524周围的将与使用者皮肤接触的所有边缘均被倒圆，以提供0.2mm的曲率半径，使得使用者感觉不到边缘。
参见图3、5至10，间隙522暴露出修剪刀片504的刀刃536。也许在图9中可最好地看出，后壁506及其下终端表面526为修剪刀片504及其刀刃536提供修剪顶盖535并限定修剪刀片504的暴露量。参见图3和10，从两端被间隔开的两个皮肤保护突出537延伸到从修剪刀刃536至修剪防护件528的切线后面的空间内，以限制使用者的皮肤可凸入修剪刀刃536和修剪防护件528之间的空间内的量。
参见图4和6，上侧突出部508和510具有上狭槽538并且下壁512具有对齐狭槽540，所述对齐狭槽用于接纳将修剪刀片组合件30固定到外壳20上的夹片32。参见图3和6，下壁512也具有凹口542，以与外壳20上的突出544配合，以有利于将组合件30对齐并保持在外壳20上的适当位置。
参见图3、6、8、9、11、12，下壁也具有四个碎屑清除狭槽546，它们与外壳20上的四个凹进去的碎屑清除通道548对齐，以允许胡须屑在剃刮期间从刀刃536后下方的区域清除。
在制造时，刀片载体502由金属片切割和成形。然后将修剪刀片504紧贴内表面532放置，其中用自动放置构件使刀刃536与对齐表面530对齐，然后通过点焊534固定到内表面532上，使修剪刀刃56相对于修剪防护件528和修剪顶盖534处于精确的位置。然后，通过将修剪组合件30向前滑过外壳20的后面而将其放置在外壳20背面，使下壁512上的凹口542与外壳20上的突出544对齐。同时，当组合件30被向前移动到外壳20的背面上时，外壳20上的上变形块552和下变形块554(图8)由于施加在上突出部508、510与下壁512之间的压缩力而变形。然后通过夹片32将组合件30固定到外壳20上，所述夹片32穿过刀片载体506上的上狭槽538和下狭槽540以及穿过外壳20的对齐狭槽550。
使用时，剃须者将手柄14从其通常被抓握的位置旋转180度，使得拇指位于靠近主防护件22一侧上的指垫726(图14和15)上，并将刀片单元的后部朝待剃刮皮肤区域移动，使修剪刀片504与待修剪毛发的边缘对齐，例如，当在其它方法难于剃剪的位置处剃剪毛发时，在需要清理鬓角底部边角、胡须边角或剃须者鼻子下面的位置处。刀片单元16相对于连接构件18位于其静态止动位置，因此当使用者将刀片单元16的后部和刀刃536压在皮肤上然后将其在皮肤上侧向移动以修剪毛发时，刀片单元不绕枢轴转动。在修剪期间被导入刀刃536后面的区域的剪下的毛发和其它胡须屑在修剪期间通过壳体20中的碎屑清除通道548和在下壁中的对齐的碎屑清除狭槽546，并在用水冲洗期间例如在剃刮或修剪操作之间，整个区域以及碎屑清除通道和狭槽易于被清洗。剪下的毛发和胡须屑也可通过在通道548后面和下壁512上方的通道549。
修剪刀片504的刀刃536相对于刀片单元的后壁506的凹进位置避免了在操作刀片架12和剃刀10期间割伤使用者的皮肤。将修剪刀片和修剪防护件包括在一个连接到剃须刀片单元外壳的同一组合件上有利于精确定位修剪防护件相对于修剪刀片的位置，以提供精确的修剪刀片切向角和修剪刀片跨度。
参见图13，可供选择的刀片支撑600包括具有间隔段604的梳状防护件602，以有利于清除胡须屑、有利于修剪鬓角和其它较长的毛发并有利于在制造工序中成形防护件期间提供精确定位的防护表面。刀片支撑体600也具有冲洗开口606以允许清除在修剪刀片504和外壳20之间捕集的毛发(参见图9)。在这个实施方案中，使外壳20和刀片之间的空间大于图10所示的空间，以有利于清除剪下的毛发和胡须屑。
参见图14，可看到剃刀700中Mach III型的手柄样式，手柄702的末端包括S形弯曲704，所述弯曲704包括第一弯曲706和第二反向弯708。当使用刀片架712的末端710处的修剪刀片在皮肤表面714上修剪时，该反向弯曲在使用者意欲放置拇指或其它手指的位置凸出来，以便提供精确的控制。
参见图15和16，手柄14在末端处包括与主刀片28在同一侧的呈凹形的单个轻微弯曲720。手柄14被分为两部分722、724，在这两部分之间提供一个空的区域以供接近位于弯曲720的凹侧的指垫726。当修剪使用者皮肤730上的鬓角、其它腮须或毛发时，与主刀片在同一侧的轻微弯曲720、指垫726和由分叉手柄提供的指垫726接近口允许使用者将拇指或其它手指与修剪刀片504齐平放置或放置在修剪刀片504的正下方，所述修剪刀片504位于图14所示的拐角728处。指垫726由弹性体材料制成并具有突出以提供良好的接合。722、724部分的内表面732、734被松弛以供接近指垫726。
