Description

柔性淋浴器臂组件
                        技术领域
本发明涉及一种柔性淋浴器臂组件，特别是带有柔性淋浴器臂的淋浴器臂组件，以便灵活地调整淋浴器喷头的位置。
                        技术背景
用淋浴器洗浴作为一种较好的洗浴方式代替了在浴缸中洗浴，其原因是多方面的，包括方便、舒服和节省能量等。一般地说，淋浴的人站在淋浴器下，通过淋浴器喷头喷出水来，淋浴器喷头连接从中心管道系统伸出的淋浴器水管。直接连接到淋浴器水管上的淋浴器喷头可以绕着与淋浴器水管的固定件而进行预定角度的运动来控制淋浴器的喷射方向。淋浴器喷头的运动限制为绕与淋浴器水管连接点的枢转运动，但不能在任意方向上平移。
对标准淋浴器喷头可调整性的改进包括开发手持式淋浴器喷头。手持式淋浴器喷头包括与淋浴器水管相连的柔性软管及与柔性软管的另一端相连的带手柄的淋浴器喷头。手持式淋浴器喷头通常安装在与淋浴器水管相连的支架上，而可以用作淋浴器淋浴器喷头，并能绕支架与淋浴器水管的连接处枢转。然而，手持式淋浴器喷头也可以从支架上取下来并用一只手将其保持在所需的位置。这使得使用者可以将淋浴器喷头移动到任何所需的位置，但需要使用者用一只手将其固持住。
淋浴器喷头定位的进一步改进包括淋浴器水管延伸装置，具有一根或多根刚性连杆，连杆的一端与淋浴器水管枢转相连而另一端与淋浴器喷头或另一刚性连杆枢转相连。连杆通常为细长的刚性管，可以在竖向和横向上进行有限的运动。运动受到刚性连杆长度及连杆之间枢转接头允许的运动方向的限制。这种刚性连杆结构通常会在接头处泄漏，变得松动而无法保持在所需的位置。
现有技术不能提供这样一种淋浴器喷头，即可以使淋浴器喷头在三维空间的不同位置上定位，同时可以使使用者的双手解放出来。本发明便是研制用来克服现有技术中的缺点的。
                        发明内容
本发明的目的总的涉及一种柔性淋浴器臂组件，通过在水源(例如淋浴器水管)和喷水器(例如淋浴器喷头)之间构造淋浴器臂的形状而使使用者可以在三维空间上多次调整淋浴器喷头的位置。淋浴器喷头的具体位置和水喷射的方向可以通过重新构造淋浴器臂的形状而简单地得以变换。柔性淋浴器臂固持在所需的位置，直到由使用者变换了为止。柔性淋浴器臂通过管连接螺母密封地连接到淋浴器水管，并通过连接结构密封和可枢转地与淋浴器喷头相连。
更具体地说，柔性淋浴器臂组件包括形成水流通道的细长柔性件；该柔性件具有第一端和相对的第二端。柔性件可反复地构造为固定形状。柔性件的第一端与淋浴器水管以流体连通的方式相连，第二端与淋浴器喷头以流体连通的方式相连。外壳从第一端到第二端将柔性臂覆盖住。
更具体地说，柔性淋浴器臂包括多个形成柔性臂的相互连接的轮圈，各轮圈可以相对于邻近的轮圈转动。多个相互连接的轮圈形成了轴向延伸的孔，并且在柔性臂的第一端具有第一端轮圈而在柔性臂的第二端具有第二端轮圈。淋浴器管连接螺母限定了延伸通过的内孔，具有与淋浴器水管流体相通的第一端和与第一端轮圈流体相通的第二端。淋浴器喷头限定了具有内孔延伸通过的连接结构，并在柔性臂的第二端与第二端轮圈流体相通。
在一实施例中，第一端轮圈具有外螺纹端和部分球形的相对端。部分球形端与相邻的轮圈相连。连接螺母的第一端有内螺纹，螺母的第二端有外螺纹，用于与淋浴器水管螺纹连接。第一端轮圈的外螺纹端与螺母内螺纹的第一端通过螺纹连接。
在另一实施例中，淋浴器喷头和柔性臂第二端之间的连接结构包括用于可转动地容纳所述第二端轮圈的保持架；用于容纳第二端轮圈和保持架的套管；及用于在套管内定位第二端轮圈和保持架的连接器。
因此，本发明的目的在于提供一种柔性淋浴器臂，可以反复调整到不同的位置而控制从淋浴器水管喷射出的水流的方向。

                      具体实施方式
包括本发明的淋浴器喷头组件30在图1-3中示出。淋浴器喷头组件30连接到从淋浴室的墙壁伸出的标准淋浴器水管32上，如图1所示。淋浴器喷头组件30包括细长的柔性淋浴器臂34，具有第一端36和相对的第二端38，沿着其整个长度形成了水流通道。柔性淋浴器臂34的第一端36与淋浴器管连接螺母40相连。淋浴器管连接螺母40又与从淋浴室的墙壁伸出的标准淋浴器水管32相连。柔性淋浴器臂34的第二端38适于容纳淋浴器喷头42。在柔性淋浴器臂34的第二端3 8和淋浴器喷头42之间采用特殊的连接结构44(见图3)。
在使用中。水从淋浴器水管32开始，通过淋浴器管连接螺母40，而进入柔性淋浴器臂34。水流过沿柔性淋浴器臂(下面将详细描述)整个长度形成的导管(连续内腔)而达到淋浴器喷头42，并随后流过淋浴器喷头。柔性淋浴器臂34可以由使用者安置在多个位置中的任何一个，使使用者可以根据所需定位淋浴器喷头42和淋浴器喷射水流的方向，如图1和2所示。
如图3所示，柔性淋浴器臂34由多个相互连接的球座轮圈46，轮圈相互连接在一起，由于球座结构，各轮圈可以相对于各相邻的轮圈枢转。各轮圈限定延伸通过的内腔48，当各内腔48相互连接形成为连续的并沿柔性淋浴器臂34的整个长度延伸时。柔性软管50通过连续的内腔48，用于将流体从淋浴器水管螺母40开始经柔性臂34运送到淋浴器喷头42。外壳52包裹住柔性淋浴器臂34的整个长度并从淋浴器管连接螺母40延伸到淋浴器喷头42的基部。外壳52保护轮圈46免受水分、灰尘或其他影响柔性淋浴器臂34的性能的杂质的损害。
更具体地说，参照图3、4和5，柔性淋浴器臂34由多个球座轮圈46组成，轮圈46相互连接而在相邻轮圈之间进行转动和枢转。轮圈最好由热塑材料制成，诸如Teflon浸渍缩醛。各轮圈46具有小端54和大端56，在两端之间形成锥形颈58。通过轮圈46形成的内腔48在轮圈46的小端54限定开口60，并在轮圈的大端56形成开口。轮圈46的小端54处的外表面为大致球形。轮圈46的大端56处形成的内腔48的内壁62为大致球形，用于可转动及枢转地容纳相邻轮圈46的小端54。轮圈46通过将第一轮圈的小端54插入相连轮圈46的大端56的内腔48中，如此类推，如图4和5所示。一个轮圈小端54的外壁与相邻轮圈46的大端56的内壁62的配合使得多个轮圈相对于相邻轮圈枢转和旋转而形成多种形状。
在轮圈46的大端56形成的内腔48的形状制成适当的尺寸而紧紧地容纳相邻轮圈的小端54，从而使轮圈在使用者的作用力下相互相对旋转和枢转。然而，一旦使用者使柔性淋浴器臂34形成预定的形状，装配足够紧密而产生了充分的摩擦力以保持轮圈的位置。在授予Lockwood Products，Inc.的美国专利5,449,206中公开了一种用于构成柔性淋浴器臂34的合适的轮圈46。然而，还可以设想：任意可以用于反复地柔性运动到固定的最终位置并可以适应所需流体的传输特性的任何结构都可以用于本目的。
特殊的第一端轮圈64用在组成柔性淋浴器臂34的多个轮圈46的第一端36以将柔性淋浴器臂34紧固到淋浴器管连接螺母40，如图3、6和10所示。第一端连接轮圈64限定具有一端68的主体66，这一端68的结构能连接到柔性淋浴器臂34中的相邻轮圈46。最好，该端68的结构是类似于上述典型轮圈46的小端的部分球形内凹外表面70。形成通过第一端连接轮圈64的内腔72，这在下面将进一步进行描述。第一端连接轮圈64具有大致圆柱形外表面部分76，限定了边缘78、靠近边缘78的环形斜密封表面80、从主体向外延伸的环形凸缘82或边缘和位于密封表面80和凸缘82之间的外螺纹84。
凸起或尖头86(见图6、10和13)从环形边缘78开始径向伸出并形成将在下面详细描述的锁定机构88的一部分。如图10和13所示，尖头86在第一端轮圈64上从环形边缘78向外伸出，并具有带缓斜度的较长第一侧面90和带陡斜度的较短第二侧面92。凸起86在边缘78上取向为：当第一端轮圈64与淋浴器管螺母40配合时，如果第一端轮圈64完全装入淋浴器管螺母40，凸起与在淋浴器管螺母40内表面上形成的对应斜面94配合，形成了“棘轮”型锁定机构88，防止第一端轮圈64从淋浴器管螺母40中抽出，例如试图通过将第一端轮圈64从管螺母40中拧开的方式。
在第一端轮圈64的全长上形成的内腔72具有特殊的形状以便于流体传输通过。在第一端轮圈64的球端，内腔72具有较大的直径并颈缩通过倾斜部分96，通过第一端连接轮圈64的中心部分而达到大致圆柱形喉部98。内腔72随后突然增大至较大直径、大致圆柱形内腔部100，内腔部100形成通到连接轮圈64的另一端74。配合表面102在从喉部98的直径到较大直径内腔部100的过度处形成，最好是与第一端连接轮圈64的长度方向成90°的表面。靠近沿着其长度的中部延伸的喉部98的第一端连接轮圈64的外表面限定第一连接轮圈64的最小外尺寸。
一对相对柔性薄片104从第一端连接轮圈64的喉部98的两侧伸出。当外壳52越过第一端连接轮圈64并插入淋浴器管螺母40时，薄片104有助于形成与外壳52的密封，如下所述并如图6所示。当外壳52的端部106越过第一端连接轮圈64并插入淋浴器管螺母40时，外壳52配合密封薄片104的自由端108并将密封薄片104向着淋浴器管螺母40弯曲。薄片104的顶端108与淋浴器管螺母40之间的空间小于外壳52的厚度，从而使外壳52在插入淋浴器管螺母40时配合薄片104。薄片104的弹性产生抵住外壳52的偏向力而将外壳52压靠在淋浴器管螺母40上，并产生紧固的连接以帮助阻止灰尘、颗粒或其他杂质的进入。此外，弯曲的薄片还起到凸轮表面的作用而产生压配合以阻止外壳52从淋浴器管螺母40中退出。
最好是由尼龙加强PVC制成的软管50插过沿柔性臂34的长度形成的内腔48并通过锯齿形的环管110而与第一端连接轮圈64相连，如图6所示。锯齿形环管110具有限定通过的轴孔112的大致圆柱形的主体，和在一端形成的环形凸缘114。主体的外表面限定锯齿116，最好是螺旋状的而使环管110容易插入软管50的内径，并阻止环管110从软管50中抽出。锯齿116具有较尖的顶端，与软管50的内径配合而卡住软管50并防止环管110从中抽出。
软管50首先插过第一端连接轮圈64的喉部98。在喉部98和较大直径内腔部100之间的过渡处，软管50的端部大致与喉部98的端部对齐。环管110随后插入软管50的孔中，从而使在环管110上形成的环形凸缘114的下表面与软管50的端部和靠近喉部98的配合表面102配合。环管110的主体制成为这样的尺寸，即当其插入软管50时，软管50的壁压靠喉部98的壁而形成水密密封，从而使水只流过软管而不会环绕软管。环管110的环形凸缘114抵靠第一端连接轮圈64的配合表面102的配合还形成了密封而有助于防止水绕软管50而流过轮圈64。
柔性淋浴器臂34的第一端轮圈64通过淋浴器管连接螺母40与淋浴器水管32相连，如图3、6和10所示。如图3和6所示，螺母具有细长主体118并限定了延伸通过的多室连续内腔120。内腔120的第一部分122具有平滑的壁。内腔120的第二部分124限定内螺纹126并且其直径略小而用于容纳淋浴器水管32的外螺纹128，使螺母40与淋浴器水管32螺纹连接。第三室130部分具有螺纹。环形支座132在内腔120的第二部分124和第三部分130之间形成。
向内延伸的斜角环形凸缘134在内腔120的第三部分130的一端形成并明显减小了内腔120的直径而与节流阀150一起控制水流。环形凹槽136绕斜角环形凸缘134的基部形成而在第一端轮圈64插入后用于容纳其边缘，如下面的进一步描述。接着在内腔120内形成环形密封支座138，支座138后形成内螺纹区140并以最后室142结束，最后室142的直径较大并限定与管螺母40的长度方向成90°的环形支承表面144。多个斜面94在靠近支承表面144的最后室142的内壁上沿圆周间隔开。这些斜面94与在第一端轮圈64的环形凸缘82上形成的凸起86结合作用而形成螺纹锁定机构88。
第一端轮圈64的端部74通过螺纹容纳在管螺母40中，直到第一端轮圈64上的密封表面80与O形密封环146配合并将其压靠在管螺母40上形成的环形密封支座138上。第一端轮圈64的径向延伸的外凸缘82同时与管螺母40上形成的平坦配合表面144配合而牢固地将第一端轮圈64定位到管螺母40上。在管螺母40的内表面上靠近平坦配合表面144形成的多个斜面94与在第一端螺母64的径向延伸外凸缘82上形成的凸起86配合而使第一端螺母64通过右手螺旋运动而旋入管螺母40。第一端轮圈64的外凸缘82上凸起86的形状阻止第一端轮圈64相对于管螺母40的逆时针相对运动而防止第一端轮圈64意外地从管螺母40上松开。如图12和13所示，联动凸起86和斜面94形成锁定机构88，基本上允许第一端轮圈64由管螺母40螺纹连接而阻止从第一端轮圈64的管螺母40中松开退出。
O形环146在第一端轮圈64和管螺母40之间形成密封，防止水绕第一端轮圈64流出而保持只从延伸通过柔性臂34的软管50中流过。外壳52的端部106位于第一端轮圈64之外，与密封薄片104配合，并位于管螺母40的端部之内，有助于将外壳52的端部106固定到管螺母40上并形成密封，而防止水、灰尘和其他杂质进入相互连接的轮圈46。
水过滤件148和节流阀150如图6所示位于管螺母40中。水过滤件148具有带外螺纹的第一部分152和带过滤结构(如网眼或小孔)的第二部分154。水流过过滤结构进入过滤器148中形成的内腔156而流出第一部分152的端部。环形凸缘158在第一部分152和第二部分154之间形成并向外伸出。过滤器148的第一部分152通过螺纹纳入第三室130，直到凸缘158与环形支座132配合为止，此时，过滤器148处于正确的位置并由淋浴器水管32的端部配合而平垫片159位于两者之间形成密封。节流阀150通过过滤器148保持在内腔120的第三部分130，并容纳经过过滤器148后的水。
特殊设计的第二端轮圈160位于柔性臂34的淋浴器喷头端以有助于淋浴器喷头42与柔性臂34的连接，如图7、8和11所示。第二端轮圈160的一端的形状构成为与柔性淋浴器臂34中的相邻轮圈46相连。优选的是，这种形状与用于形成柔性臂34的联动轮圈结构的典型轮圈46的较大端56相同，为接收的或凹形的第二端轮圈160的端部162。第二端轮圈160的相对的或凸形端164为大致球形外表面166。穿过整个第二端轮圈160形成的内腔168具有中间喉部170，喉部170在第二端轮圈160的接收端162转换为部分球形部分172(用于接收如上所述的典型轮圈46的小端52)；和靠近第二端轮圈160的凸形端164形成直径大于喉部170的部分，形成环管的配合表面174，用于将软管50连接到第二端轮圈160上。如上相对于第一端轮圈64描述的环管176用于将软管50的端部以通过第一端轮圈64描述的相同方式紧固到第二端轮圈160上。因此，当软管50位于喉部170中时通过将环管176插入软管50在软管50和喉部170的侧壁之间形成密封。环管176的向外伸出的凸缘178与由从喉部170向内腔168的较大直径部分过渡形成的配合表面174配合。
指状套管180用于与淋浴器喷头内部本体182结合作用而将第二端轮圈160的小端固定在淋浴器喷头42的基部锥体184上。指状套管180具有大致圆柱形主体186和环形密封边190，主体186带有从主体186周边开始纵向延伸的指状件188，环形密封边190形成在指状套管180的主体186的内壁上。密封边190靠近从指状套管180的主体186伸出的指状件188的基部但位于其下。压密封结构192绕指状套管180的主体186的外表面形成并且为绕主体186在圆周上延伸的带圆角的凸起。
淋浴器喷头42的基部锥体184具有形成穿过的通路196的套管194和部分锥形边204，套管194的一端198处于淋浴器喷头42之内，具有内螺纹200，而另一端202处于淋浴器喷头42之外，具有由于向内的斜度而尺寸减小的开口203，锥形边204限定将在下面进一步描述的内指状配合表面206。
淋浴器喷头内部本体182形成了外螺纹的连接器端208和靠近连接器208的螺纹端的轴向凹槽210。轴向凹槽210具有基壁212和平滑侧壁214。
在将第二端轮圈160与淋浴器喷头42的基部锥体184连接时，第二轮圈160的凸形端164插过基部锥体184中尺寸减小的外开口203。指状套管180随后定位在第二端轮圈160的凸形端164上，从而使指状件188沿第二端轮圈160的凸形端164的大致整个长度上延伸，并且指状套管180内壁上的密封边190连续地配合第二端轮圈160的凸形端164的外表面166。淋浴器喷头内部本体182的外螺纹连接器208随后通过螺纹容纳在基部锥体184的套管194的内螺纹端200内。指状套管180的主体186上的外环形凸起192配合在淋浴器内部本体182的连接器208端部形成的轴向内腔210的光滑内壁214，而在指状套管180和淋浴器喷头内部本体182之间形成水密密封。指状套管180的端部与淋浴器内部本体182中内腔210的基壁212配合，并且随着连接器208旋入基部锥体184，内腔210的基壁212向着套管194上尺寸减小的开口203压指状套管180。外开口203的颈缩部分204的指状配合表面206迫使指状套管180上的指状延伸部188围绕第二端轮圈160的凸形端164的部分球形外表面166，而可转动地卡持第二端轮圈160的凸形端164并防止第二端轮圈160从基部锥体184上抽出。此外，密封边190在指状套管180和第二端轮圈160之间形成水密密封。指状延伸部188的厚度足以将第二端轮圈160的凸形端164保持在基部锥体184中。
内环形密封边190压靠在第二端轮圈160的凸形端164的外表面166而在第二端轮圈160和指状套管180之间形成水密密封。
颈缩配合表面206为部分锥形，其功能是将指状套管180的指状延伸部188围绕在第二端轮圈160的凸形端164的球形表面166，这在第二端轮圈160的凸形端164上产生摩擦夹持力，形成压配合而防止第二端轮圈160的凸形端164从基部锥体184上抽出。基部锥体184可以绕第二端轮圈160的凸形端164转动，同时保持第二端轮圈160和指状套管180之间的密封，这是因为在淋浴器喷头42绕凸形端164转动时密封边190与第二端轮圈160的凸形端的外表面保持接触。在功能上，淋浴器喷头42的转动更类似于第二端轮圈160与下一个相邻轮圈46的转动，然而，在淋浴器喷头42和第二端轮圈160之间还可以进行一定的枢转。通过第二端轮圈160、指状套管180，进入淋浴器内部本体182而形成连续的水流通道，由于通过淋浴器喷头喷水，通道具有足够的密封性来防止在相连接的零件周围的泄漏。
淋浴器喷头基部锥体184绕着套管194但与其间隔开而形成环形凹槽216。环形凹槽216接收外壳52的端部218而赋予最终产品精细的外观，并将外壳52的端部218密封到基部锥体184而防止水、灰尘和其他杂质进入相互连接的轮圈。楔形套管220有助于将外壳52的端部218保持在凹槽216中，并提高密封特性，如图8所示。楔形套管220大致为圆柱形，具有薄的侧壁并在其第一端的外表面上形成楔形环222。尖锐的环形边缘224(图9)在靠近第二端的楔形套管220的内表面形成。
在采用楔形套管220作为固定器时，楔形套管220首先置于外壳52的端部218上，使得楔形套管220的第二端大致与外壳52的端部218对齐。重要的是尖锐边缘224要与外壳52配合。楔形套管220和外壳52随后压入环形凹槽216，环形凹槽216制成为紧紧地容纳楔形套管220和外壳52，因此将尖锐边缘224压入外壳52而将两者固定在一起。楔形套管220和外壳52插入凹槽216，直到下列情况为止：楔形套管220与基部锥体184的端部配合，并弹性向外偏压基部锥体184的部分，而产生外壳52和楔形套管220与基部锥体184更紧密的配合，形成足够的密封。
或者，U形弹性卡环可以附着在外壳52的端部218上而有助于将该端部保持在凹槽216内。卡环具有向内和向外延伸的倒刺。向内延伸的卡环卡住外壳，而向外延伸的卡环配合凹槽216的壁。倒刺的方向是能防止端部218从凹槽216中抽出。通常，两个或三个卡环位于外壳的端部以提供充足的卡持力。
如图1、2和5所示，环绕柔性臂34的整个长度的外壳52为大致圆柱形并沿外壳52的整个长度形成内腔226。螺旋肋228在外壳52的外表面形成而提供对外壳52的结构支承，并有助于外壳52随着柔性臂34的运动平滑地弯曲。靠近第一端轮圈64的外壳52的端部106插入淋浴器管螺母40而形成紧固接点。靠近淋浴器喷头42的外壳52的端部218插入淋浴器喷头基部184，也形成紧固接点。外壳52的两端都被固定，则水、水分、灰尘或其他杂质很难进入联动的轮圈46。已经发现，水、水分、灰尘或其他杂质通过使联动轮圈46产生噪音或相互之间运动不顺滑而使联动轮圈46的性能降低。外壳52比单独的轮圈46容易清洁，因此更加便利。外壳52最好由化学阻性热塑材料制成，诸如聚乙烯。肋228在外壳52的外表面形成而产生出波浪形外表面。轮圈是螺旋形的，为外壳提供结构上的强度。根据柔性臂弯曲的方式，轮圈之间的构件压缩或折叠或延伸。
在工作时，淋浴器管连接螺母40通过螺纹容纳在淋浴器水管中而形成密封，并使水流通过柔性淋浴器臂34而到达淋浴器喷头42。水流过淋浴器管连接螺母40、连接淋浴器管连接螺母40的第一端轮圈64，进入通过联动轮圈46中心的软管50。水在软管50中经过靠近淋浴器喷头42的第二端轮圈160，并最终通过淋浴器喷头42喷洒在使用者身上。
连接淋浴器管螺母40的第一端轮圈64提供第一端轮圈64和连接螺母40之间的水密密封，及软管50和第一端轮圈64之间的密封，从而使淋浴器水管34中的水只从软管50流到淋浴器喷头42并因此减少泄漏。第二端轮圈160与淋浴器喷头42相连而使淋浴器喷头42在第二端轮圈160上枢转，同时保持第二端轮圈160与淋浴器喷头42之间的水密密封。
为了将淋浴器喷头定位在所需的位置，使用者只需抓住淋浴器喷头42并运动喷头而使柔性臂弯曲到所需的构型，将淋浴器喷头42定位在多个位置之一上，这些位置包括横向的、竖向的、向前的、向后的位置或各种实际的组合。一旦定位，柔性淋浴器臂34保持其形状，直到使用者改变其形状为止。淋浴器喷头臂34的长度只受淋浴器42重量、与淋浴器水管32连接的结构强度和与轮圈46配合在一起而形成柔性淋浴器臂的紧密性的限制。
已经对本发明的优选实施例进行了具体描述。这种描述是通过优选的例子进行的。应该明白，本发明的范围由所附权利要求书限定，而不是由优选实施例的详细描述限定。
