Description

剃须系统
本发明涉及剃须系统，更具体地说，涉及到湿剃须型的保安剃刀。
已知的剃须系统包括两或多块刀片，它们以相互分开平行关系设置，使得在一次剃须行程中，刀片的刃口能相继地对于拟进行刮剃掉的胡须起作用。各式各样的须疵一类残屑会逐渐淀积，常常堆聚于两相连口刃的区域间而不利于剃须系统的剃除性能。已提出过多种用来除去这类残屑的装置，包括形形色色的推净装置。
此外，在上述剃须系统中，还常须将剃刀头相对于柄部固定，以致整个剃刀结构在完结其使用寿命时会废弃掉。最好是能在柄部与剃须头之间有一偶联机构，而此种偶联机构要同用模压技术来经济地制造剃刀部件相一致，并可在柄部与剃须头之间形成机械式的牢靠连接。
本发明的目的是提供一种剃须系统，它有一闩合结构，可保证剃须头在柄部上的良好接合和固定。
依据本发明的一个组成部分，提供了这样一种剃须系统，它包括，一个带有一支承面的平台件以及一设置于此支承面前向的保安结构；一个盖件；一个部件，它具有一批柱件用来置入另一部件的孔中；一块具有平面体与刃口的主刀片件，一块具有平面体与刃口的副刀片件，每块刀片件上有一批孔，其中至少有两个孔具备着相分开的定位表面，用来与上述柱件作定位配合；以及一批配置于这种柱件之上且处于主、副刀片间的分离的隔垫件。上述柱件穿过刀片件、隔垫件与另一部件中的孔，且最好可机械变形，使此主、副刀片件以其刃口按相分开的平行关系固定于一不变的剃须几何结构中。上述隔垫件使主、副刀片件相分开，而让二者的刃口间保持着预定的垂向间距，同时，上述柱件则使此两刃口相对于所述保安结构保持住预定的横向间距。这些个隔垫件最好能给出一批相分开的冲洗通道，它们沿着一与刃口大致垂直而与刀片件平面大致平行的方向延伸，在一特定的实施例中，每条冲洗通道约有0.5mm深和至少约4mm宽。柱件则最好从盖件上垂下而与刀片件中孔内的定位面配合，以使刀片件的刃口定位于所需的剃须几何结构中；在一特定的实施例中主刀片具有约24°的刀片切角、约1.5mm的跨距以及约0.02mm的露头。在一些最佳实施例中，有剃须辅助材料固定于盖件之上。
根据本发明的另一组成部分，所提供的剃须系统具有一柄部件以及一剃须头组件，它包括有至少一块刀片件，刀片件的刃口则与一保安机构相邻。此剃须头组件包括带有一对相对分开之表面的插座部、形成于此两表面之一中的闩合结构、以及形成于此两表面之另一中的与该闩合结构相对的锁刃结构。此手柄部则包括一手持部与一用来插入剃须头组件插座部中之突出叉头部。叉头部包括一体部与一梢部，此梢部有一从其一侧突出的闩合突起和在其另一侧的闩座，后者可分别接合此闩合突起与锁刃结构，使得插座部的两匹配面与叉头部按牢靠的配合形式固定位。
叉头部最好包括一与在插座部一内表面上的支座面相配合的支座面，在插座部与叉头部上均设有辅助的沿轴向延伸的导向面。在一特定的实施例中，于插座部中设有一与锁刃结构相邻的凸轮面，用来将闩合突起沿此凸轮面带到插座部的闩合结构之上，同时插座部还包括一裙部，它在相应的支座面下延伸，相对于插座部构成一倾角(约150°)。在剃须头组件与柄部间的过渡部有一与柄部件之平面构成一约150°角的轴线，使得保安结构处在过渡部轴线前方0.5cm和在手持部轴线前方1cm处。
本发明的其它特征与优点，可随着下面结合附图对一特定实施例所进行的描述而得以理解，在附图中：

下面对一特定的实施例进行描述。
图1与2所示剃刀组件10包括柄部件12与由弯曲过渡部16连接之剃须头部件14。柄部件12是由高度耐冲击的聚苯乙烯模压而成，具有一约8cm长、约1cm宽和1cm深的手持部18，此手持部有一轴线20。过渡部16有轴线22垂直于剃须头14的刀片平面24且与轴线20构成一155°的角，并在沿轴线20上有一约1cm的长度，在沿轴线22上有一从轴线20至剃须头14底座的约1.5cm的长度。剃须头14包括由高度耐冲击聚苯乙烯模压成的平台件30和盖件44。在过渡部轴线22前方约0.5厘米、在一优选实施例中为6毫米(尺寸A)和在手持部轴线20前方约1厘米(尺寸B)处，设置有保安面34。
剃须头14与过渡部16的更详细情况可参看图3的部件分解图。剃须头14包括一带有整体插座结构32的底座或平台件30、横向延伸的保安结构34以及平面部36，在此平面部上配置有钢制的主刀片件38与钢制的副刀片件40，它们由分散开的铝制隔垫42A～D保持成分隔开的关系。在此实施例中，上述刀片件38、40与隔垫是由盖件44固定到平台件30之上，而此两刀片件配置成相互平行并与图2的平面24平行。
在支承用平面部36上形成有一系列压缩性凸耳48和4个分隔1cm间距的定位孔50A～D。朝前延伸的端壁部52与支承梁腹54两者在平台部34的前缘表面58与保安结构34之间界定出排减槽或凹座56。
每个刀片件38、40均有相平行的前后刃，各刀片件的前刃经锐化而确定出一刃口60。每块刀片长约4cm，主刀片38宽约7mm，副刀片40宽约5.5mm。各块刀片上形成有一列共四个矩形孔62A～D。居中的两个孔62B与62C长均约为3.5mm，宽均约为2.75mm，而外侧的两个孔62A与62D则各有一构型与居中孔62B与62C类似的基干部和一宽约2mm而长约2mm的定位延伸部64。主刀片38之定位部64P的中心线距刃口60P为4.8mm，而副刀片定位部64S的中心线距刃口605为3.3mm。刀片38与40之间设置有铝制隔垫42A～D，各隔垫厚约0.5mm，各有约5mm的外径和一约2.1mm直径的孔。
盖件44包括有在两个前向延伸端部72、74间的横向延伸部70。柱件76A～D(各具有约2mm直径和约4mm长度)从横向延伸部70上朝下伸展，分别与平台、刀片和隔垫中的孔50、62、64和66对准。柱件76的自由端是空心的，以利于冷锻作业。延伸部70的顶面包括含聚氧化乙烯之剃须辅助材料的模压插片80。
正如图4～6中的前视、顶视与剖面图所示，在组装好的剃须头14中，主刀片38的刃口60P在平台30的前壁58与保安结构34的后表面间之排减槽或凹座56上方延伸，而副刀片40的刃口60S由于通过与刀片38和40的定位面64、平台的孔50以及隔垫42A～D作定位配合而定位，则与主刀片38的刃口60P从上方分开约0.5mm而在后方分开约1.5mm。柱件76使刀片件38与40的刃口60P与60S相对于保安结构34和盖件44定位，经由隔垫42为刃口60提供稳定的支承与垂向间距。如图4、5与7中的箭头82所示，分隔开之刀片间的须疵残屑便可以方便地沿着隔垫42间的流道冲洗净。如图6与7所示，此最终的刀片几何结构给出了约24.5°的主刀片切角、约22°的副刀片切角、约0.02mm的各个刀片的露头、约1.3mm的主刀片跨距和约1.6mm的副刀片跨距。
柄部12与剃须头14间过渡部16的偶联情形可以参看图3与图7～9。这一偶联机构包括平台件30的插座部32和柄部12的偶合叉头90。叉头90从倾斜面92延伸出且包括有分隔开的导向梁腹94(图3)，这些梁腹具有平行的导向面95并界定出一具有底座面96的凹座，此凹座长约4mm而深约0.5mm，同时在叉头90的各侧具有辅助的导向梁腹98，它们则有长约2mm和平行于表面95延伸的导向面100。叉头90到倾斜面92的中心之长度约7mm。闩合突起102在离倾斜面92的远端具有一约1/3mm的半径，并从叉头表面104上一个离底座面96有4.75mm距离的点向前延伸约0.7mm。在叉头90的后表面108上形成有闩座106。
插座32包括有如图3、8与9所示之卵形构型的悬套部110，并具有后方的内表面114和前方的内表面116。卵形端表面112则具有约3mm的深度和约8mm的宽度。上述后表面114与前表面116相对于插座32的轴线分别倾斜成2°与约5°的角。凸轮面118(图7)设置在上述表面114的上端相对于该表面成一约45°的角。于前表面116的上端形成有一与凸轮面118分开约1.5mm的闩合肩120。从凸轮面118上朝上延伸出的垂向壁122则界定出一闩合边凸出部124，以与叉头闩座106接合。在插座前表面116上则形成有一凸脊126，此凸脊的下部基准面128距闩合肩120约4.75mm并处在叉头的凹底座面96上。在插座内侧壁130上形成有几个凸耳132，它们的导向面134如图9所示与叉头导向面100配合。此外，有裙部136从表面128延伸到端面112。
装配时，将叉头90插入悬套110内，以其仿随凸轮面118的前端面作为脊126，使导向面100与导向面134配合，并为导向面95所导引，直至插座脊的基准面128座落到叉头凹底座面96上。与此同时，将闩合突起102滑移到闩合肩120之上，并使闩座106与闩合边凸出部124锁合上，以使剃须头14牢牢地固定于柄部12之上，而由闩合突起102与闩合肩120的弹性相互作用，使两个配合面96与128牢靠地贴合。
如上所形成之坚固的剃须刀组件能提供优质的剃须效果。
尽管已于上面示明并描述了本发明一特定的实施例，但熟悉本项工艺的人当可了解到它的种种变更形式，因而本发明不应受所公开的实施例或其细节所限，而是可以在本发明的精神与范围内作出各式各样的改型。
