Description

改进的床垫上的边缘支承件
发明领域
本发明涉及一种用于床垫的边缘支承系统。
发明背景
内装弹簧的床垫通常是通过将一个线圈矩阵对齐并在每个线圈的末端处用螺旋钢丝将各线圈系在一起进行装配。位于矩阵边界处的线圈和螺旋钢丝固定到绑结钢丝上,上述绑结钢丝在每个弹性线圈末端的平面中构造弹性线圈矩阵。类似的内装弹簧组件可以用于制造床垫之外的家具如软垫弹簧座椅和沙发。线圈和钢丝的内装弹簧组件用衬垫层、旗布层、结实的条纹棉布层和装饰性材料层包封,以便提供一种人可以在上面坐、躺、或睡的舒适表面。床垫一般是人工装配,因此希望床垫元件简单和快速而方便地装配在一起。
床垫的边缘或周边一般要求较大的结构支承件,以便保持床垫的形状。由于床垫的使用者需要从床垫的周边上下床垫,所以需要较大的边缘支承件。在那样进出床垫时,人可以在床垫的边缘上坐或者站一段时间。人还可以用一个床垫的边缘作为坐位。位于矩阵周边上的内装弹簧线圈将经受人坐或站在床垫边缘上的增加的载荷和载荷周期。因为当人坐着时,在少数线圈中所分布的人体重量对于当人躺在床垫上时在一线圈阵列上施加的更均匀分布的重量来说,将更集中的载荷施加在受影响的线圈上。在床垫边缘处增加的载荷和载荷周期加速对边缘上的磨损,并导致床垫边缘变圆。这种变圆通过在床垫边缘处聚合的衬垫和家具覆盖饰物材料层加重。
为了在床垫周边处提供额外的支承件,现有技术床垫装有一种木质边界件或衬垫或泡沫塑料插件,上述插件与床垫内装弹簧线圈互锁式接合。木质边界件造成床垫很重并因此更难以移动。另一些由衬垫或泡沫塑料条插件组成的其它边缘支承件插在各线圈的每圈之间或在单个螺旋线圈之间并围绕各单个螺旋线圈。泡沫塑料条或片一般包括在一侧上的平面壁,而相对壁加工成一定形状,以便装配在各相邻的线圈之间或者各线圈的各圈之间,并且通常限制在上面和下面绑结钢丝之间。插件需要采用专用的拐角增强片,上述拐角增强片围绕位于内装弹簧中各线圈的近似矩形阵列拐角中的线圈装配。
将内装弹簧边缘和拐角支承元件进行挤塑加工,并常常具有复杂的截面区域。复杂的截面区域在制造期间需要附加的挤塑机维护,因而增加了成本和制造时间。床垫组件附加的挤塑泡沫塑料片也由于增加的材料层而使床垫的缝制变复杂,上述增加的材料层必需是围绕缝制针脚密布或者加入缝制针脚中。要求围绕整个床垫增加支承件的各个边缘和拐角支承元件的数量一般增加装配时间和成本。
因此,需要有一种床垫边缘支承系统,所述床垫边缘支承系统对增加的边缘支承件可以被连续挤塑和用于完全包围床垫边缘。床垫边缘支承系统可以作为连续带安装在一个床垫的线圈矩阵上,或者可以被切分成更小的长度,此处将一个或多个更小的长度安装在线圈矩阵上。另外需要床垫边缘支承系统能减少装配时间和使床垫缝制简化。
发明概述
本发明提供一种用于床垫的连续挤塑边缘支承插件。边缘支承件具有一C形横截面,或者横截面可以从“C”的内部拐角朝形成假想的E形横截面的中心逐渐增厚。当安装在床垫上时,横截面的增厚部分可以与内装弹簧的各圈一致,但不需要在各圈之间交错。边缘支承件安装在内装弹簧组件上,以便它包围二者的绑结钢丝。边缘支承元件的制造是经济的,因为它是简单横截面的单个挤塑单元,并因此不需要过多的挤塑机维护。床垫组装通过用整体边缘支承单元而简化,因为边缘方便而快速地围绕整个内装弹簧组件的绑结钢丝而包封,并且对边缘支承件不需要专门设计的拐角片。可供选择地,边缘支承系统可以在挤塑之后切分成若干小的长度或分段,或者挤塑成较小的长度,并且在床垫装配期间通过各分段安装。另外,通过消除在使用分开的拐角支承片情况下另外存在的附加泡沫塑料或材料而使床垫缝制简化。

发明的详细说明
本发明的一个实施例提供一种装配好的床垫10。床垫通过将若干线圈20安排成基本上是矩形阵列并用一种螺旋钢丝32将线圈20绑在一起装配。螺旋钢丝32和线圈20用金属夹或钢丝(未示出)固定到上绑结钢丝22和下绑结钢丝24上。边缘支承插件26具有一种带一个上支脚28和一个下支脚30的C形横截面。在床垫装配期间,边缘支承插件26通过将边缘支承插件26的上支脚28与上绑结钢丝22搭接,和将边缘支承插件26的下支脚30与下绑结钢丝24搭接,围绕内装弹簧矩阵的周边安装。当安装好时,边缘支承插件26如图1a所示完全包围上和下绑结钢丝22,24,并通过若干紧固件29如拱形环围绕内装弹簧的周边固定在合适位置,上述紧固件29将边缘支承件26连接到绑结钢丝22、24上,如图3中所示。绑结钢丝22、24和边缘支承插件26的构造在装运和使用期间还对绑结钢丝22,24提供保护。
图1c的边缘支承件40示出在C形剖面的内部区域中一种增厚部分42。增厚部分42是一种横截面表面的逐渐倾斜,上述逐渐倾斜的表面在边缘支承件40的中心会合。增厚部分42的起始点44,46可以与内装弹簧线圈20的各圈一致,如图1c中所示,但不需要这种一致影响边缘支承件40的作用。因此,边缘支承件的横截面具有一种假定的E形。
边缘支承插件26或40可以如图1b中所示绕线圈20矩阵的拐角弯曲,或者可以制造成沿着边缘支承插件26,40的长度在规定的位置处具有一个拐角弯曲区34。边缘支承插件26,40用一种挠性聚合物制成,并且可以是聚乙烯包装用的泡沫塑料。边缘支承插件26,40可以制成大的长度,并卷起以用于装运,或者可以切断成较短的长度,此处将多于边缘支承插件26,40的一个长度围绕内装弹簧线圈20的矩阵安装。大长度边缘支承插件26,40的材料的卷起还有助于制造效率,因为挤塑机操作最有效地与可以卷起的材料结合。材料卷在装配现场也比各单件更有效地处理。然后可以将边缘支承插件26,40材料卷在床垫10装配地点处切割以便定尺寸。边缘支承插件26,40在上支脚28和下支脚30之间的宽度可以根据床垫10内装弹簧线圈20的总尺寸改变。
线圈20、钢丝32、绑结钢丝22、24和边缘支承插件26,40的组装如图3所示用隔离层50,家具覆盖饰物材料层52,和填褥隔层54包封。边缘支承插件26,40的设计简单性能通过提供比较光滑的边缘和拐角改善家具覆盖装饰物材料52和填褥隔层54的缝制,上述光滑的边缘和拐角消除了使缝制困难的材料束。
应该理解,在本文所说明的实施例中优选的各种改变和修改对本领域的技术人员来说是显而易见的。在不脱离本发明的精神和范围及不牺牲附带优点的情况下,可以进行这些改变和修改。因此,打算这些改变和修改都被所附权利要求书包括在内。
