根据本发明的剃须刀头在图中都用附图标记1来表示。
具体实施方式
剃须刀头1包括一防护件2，其后称作板式防护件，一与板式防护件2安装并紧固的刀片组件3，和一用于连接手柄端部、具有闭锁装置5的板式后盖4。
板式防护件2基本上成矩形的，并包括一平坦基部件6和一从基部件6基本垂直突出的外围壁7。
外围壁7和基部件6一起限定出一内部空间8，其中刀片组件3如下文所述在安装剃须刀头1时，容纳进内部空间中。
板式防护件2设有矩形开口9，其沿基部件6延伸，因而在其相对侧上限定出一在直线外围壁部分11上的防护杆10。
基部件6具有一基本平坦的下部或内表面12，其朝向内部空间8，以及具有一相对的外部或上表面13。
如图5描述，剃须刀头1设有一润滑带14，其被粘结或与板式防护件2一起共同喷注在上表面13上，以及设有一外壳接触元件15，其也被粘结或与板式防护件2一起共同喷注在防护杆10上。
板式防护件2设有至少两个基本垂直突出内部表面12的紧固销16。如图3所示，优选设置四个紧固销。
如图3所示，板式防护件2还设有两个定位销17，18，其彼此相对地位于外围壁17和基部件6之间的交接点处。此外，板式防护件2在矩形开口9的每一端21，22处设有锥形表面19，20，用于支撑刀片的相对端23，24。
刀片组件3包括至少一个刀片和一个紧固板。在图3所示优选实施例中，刀片组件3包括三个刀片25，26，27，两个隔离板28，29和一个紧固板30。
更详细地，刀片组件3包括一狭窄或第一刀片25，一狭窄或第一隔离板28，一中间或第二刀片26，一中间或第二隔离板29，一宽的或第三刀片27，以及最后一紧固板30。
每个刀片25，26，27由冲压金属带形成，其一侧被磨利以形成刀片边缘31。
每个刀片25，26，27还设有紧固孔32，其能与紧固销16配合。每个刀片25，26，27具有两个相对端23，24，其设有能与定位销17，18配合的矩形切口33，34。
相应地，隔离板28，29和紧固板30由金属或塑料条形成，设有能与紧固销16配合的孔35。其后可以看出，每个隔离板28，29能被用作安装在最末的刀片上的紧固板30。
板式后盖4包括一基本上为矩形的本体36，其具有与板式防护件2相同的轮廓。
矩形开口37设在本体36中，如下所示，其具有能与板式防护件2的外围壁7的上表面39配合的平坦边缘38。
板式后盖4形成一个与剃须刀手柄紧密配合的适配器。
如图2所示，板式后盖4在板式防护件2的相对侧上设有两个突出固定器40，41，其在自由端处分别具有向内延伸的相对横档42，43，每个横档42，43具有各自的弧形上部表面44，45，其面向一相应的圆柱形表面46，47。
横档42，43与相应圆柱形表面46，47连接，限定出弧形槽48，49，该槽适合支撑剃须刀手柄端部的轴承壳，在轴承壳上剃须刀头将可枢转地和可移动地连接通过板式后盖4。
在固定器40，41的中部，板式后盖4包括支柱形式的凸轮装置50，其基本上垂直延伸地通过开口37，支柱50包括在顶点53交接的凸轮表面51，52，在表面51，52间限定一钝角。凸轮装置50用于接收凸轮从动件，其操作推动剃须刀头1到相对于剃须刀手柄给定的静止位置。
剃须刀头1与手柄端部的连接在美国专利4,492,025中被进一步详细描述，该专利的整个内容因此合并参照。
根据本发明生产剃须刀头的方法在其后描述。
这种方法包括如下步骤：
—提供板式防护件2；
—将刀片组件3紧固到板式防护件2上；
—提供板式后盖4；
—在刀片组件3的同侧上将板式后盖4紧固到板式防护件2上。
按照刀片组件3中的刀片数量，提供几个用于实施将刀片组件3紧固到板式防护件2上的步骤的实施例。
一个刀片
在剃须刀头1中只设有一个刀片25，将刀片组件3紧固到板式防护件2上的步骤包括：
—提供刀片25，其具有紧固孔32和切口33，它们分别与紧固销16和定位销17，18对准；
—将刀片25安装到板式防护件2上，刀片25抵靠基部件6的内表面12，紧固销16穿过紧固孔32，定位销17，18与切口33，34配合，刀片端部23，24抵靠锥形面19，20以及刀片边缘31通过并沿板式防护件2中的矩形开口9延伸；

因此，不论刀片的数量如何，将刀片组件3铆接到板式防护件2的步骤是在安装板式后盖4的步骤之前进行的。换句话说，刀片组件3与板式后盖4分离和独立地固定到板式防护件2上，使得万一板式后盖从板式防护件意外分离时，避免了刀片的散开。
此外，由于刀片组件3与板式后盖4独立地固定到板式防护件2上，如下所述，可牢固地将板式后盖固定到板式防护件。
此外，因为紧固销16只固定刀片组件3，刀片组件通过紧固板夹入中间，紧固销比普通的紧固销短，因而它们更坚固，并较少有刀片意外从板式防护件2分离的风险。
如图2和5所示，板式后盖4形成一盖子，其在紧固到板式防护件2上时，封闭了内部空间8，刀片组件3不能被接触地放入其中。
当然，板式防护件2的厚度，即外围壁7的高度，应该适合于刀片组件3的厚度，这取决于刀片的数量。
如图5所示，在刀片组件3被铆接后，卷边头54不从板式防护件2的内部空间8向外突出，使得当安装在板式防护件2上时，板式后盖4不被阻止抵接板式防护件2的外围壁7。
如图5进一步所示，板式后盖4被激光焊接到板式防护件2上。这里提供激光源，其通过一柔性激光束引导元件56连接到激光焊接头55。激光焊接头55安装到臂57上，该臂57在垂直于板式后盖4和板式防护件2之间的界面59的方向上被可滑动地安装在夹紧元件58上，该方向由箭头F1示出。此外，激光焊接头55是相对于夹紧元件58可滑动的，在与板式后盖4和板式防护件2之间的界面59基本平行的方向上滑动，使得激光焊接头55能如图6所示沿预定的焊接通道60移动，通道遵循外围壁7的轮廓线。
在图5所述的优选实施例中，板式防护件2安装在组件底侧上，而板式后盖4安装在组件的顶部上。因为激光焊接束61来自于顶部，板式后盖4和板式防护件2必须由合适的聚合物制成以允许激光焊接。在这种特定情况下，板式后盖4对于激光束61必须是透明的，而平台防护2相反是吸收的。由于激光波长在不可见范围之外，两部件2，4可以根据生产者的需要被染色，以使它们对于激光束61分别具有足够的透明度和不透明度。
此外，通过板式后盖4和板式防护件2的搭接(即通过边缘38和顶部表面39的连接)来形成的界面59必须具有足够的面积以防止焊接通道或熔化区域60接触界面59的边缘。
激光焊接方法在美国专利US6,201,211中被进一步详细描述，其整个内容在此作为参考。
如上所述，这种焊接方法被用于将板式后盖4激光焊接到板式防护件2上，这是由于需要将两部件2，4彼此牢固地固定在一起，以避免在剃须时分离，这会伤害使用者的脸部(或者其他身体区域被割伤)。还有一种需要是防止玩剃须刀的孩子很容易地将盖平台4从板式防护件上分离，这样会容易接近刀片。
激光焊接还能被用于焊接剃须刀的其他塑料部件，该部件需要牢固地紧固在一起。
例如，在带有包括几个塑料部件的手柄的剃须刀中，根据本发明剃须刀的生产方法包括将手柄的至少两个塑料部件激光焊接在一起的步骤。
激光焊接的技术可以与先前所述相同，因而，塑料部件中的一个必须是透明的，以允许激光束传送，而其他部件是可吸收的。
一个部件可以是手柄的上部部件，另一个是下部部件，上部和下部部件被激光焊接在一起形成整个手柄。
一装饰的插入物(如用于广告目的)可以夹在上部和下部部件之间，插入物通过透明的上部部件而可见。
