Many modifications and other embodiments of the invention set forth herein will come to mind to one skilled in the art to which this invention pertains having the benefit of the teachings presented in the foregoing descriptions and the associated drawings。 Therefore。 it is to be understood that the invention is not to be limited to the specific embodiments disclosed and that modifications and other embodiments are intended to be included within the scope of the appended claims。 Although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation。
That which is claimed:
1。 A leg structure for supporting a cross-rail support system for use in a bed frame to support a mattress, the leg having an adjustable height that extends generally perpendicular to the cross-rail support system and comprising:
a series of telescoping extensions。 wherein the extensions are movable relative to one another。 at least one locking member extending between a pair or adjoining extensions for inhibiting the adjoining extensions from moving relative to each other when the locking member is engaged, and an open ended groove defined in a third extension。 The groove having a width sufficient for receiving the locking member and having a length extending from one end of the extension towards an opposite end of the extension to allow the locking member and one or both of the adjoining extensions to move at least partly within the third extension。
2。 The leg structure of claim l。 wherein the groove has length allowing both of the adjoining extensions to move completely in and out of the third extension。
3。 The leg structure of claim l。 further comprising a floor 25 glide having a screw-type stem。 wherein the stem engages a threaded insert in the most inner telescoping extension。
摘要 一种与床架配合使用的交叉导轨轨系统,用来支撑具有至少两个可调支撑腿组件的床垫,并连接两个平行相邻的细长梁。所述支撑系统的整体宽度是通过沿其长度方向滑动细长梁调节,两个支撑腿组件的放置也通过滑动细长梁组件可调,并且独立于所述支撑系统的总宽度。此外,腿组件保持在细长梁彼此平行排列,并对床垫提供支撑。腿组件包括具有伸缩扩展功能的锁定装置和至少一个容纳锁定装置的开口槽。文献综述

发明领域本发明涉及一种用于支撑床垫的床支撑框架,更具体地说,是可调整的跨轨支撑,以适应该支持一系列床垫尺寸的床架。
发明背景
常规的床一般由一个框架、一个由所述框架支撑的弹簧箱和搁置在弹簧顶部的床垫组成。传统的框架一般包括床头板、脚踏板、两对间隔平行的侧轨,形成一个弹簧箱能放置在其上的矩形。间隔开的平行的侧轨支撑框弹簧床垫的外周,尽管这样足以满足大多数较小的床,但矩形的配置不能充分支持大多数大床,如大号或特大号床的中心,铺的重量高达70%搁在床的中央“支撑区”,而支持区域的支持不足会导致床垫不稳和弯曲。这样的弯曲和床垫的不稳定可能会造成使用者的身体不适和床垫和床架的过度磨损。
床的中心区提供支持的一种方法是使用多个木条(或横梁的支持),其余在框架的侧轨和沿床的宽度。不过。 木板一般都是不可取的,因为他们缺乏刚性,床上用品和人的重量容易使得它弯曲和折断。 轨交支持系统伸缩腿架英文文献和中文翻译(8):http://www.youerw.com/fanyi/lunwen_91411.html
