    • A leg construction for a folding bed frame is disclosed in which a sheet metal leg is received generally within the confines of an angle iron end rail and is secured to the inside surface of the end rail. An upper portion of the leg is supported in underlying relation to the horizontal member of the end rail for additional support. An integral tab on the leg extends upwardly through a slot in the end rail and provides a positive stop for engagement with the adjacent pivotally attached side rail to define a right angled position between the end and side rails.
    • 公开了一种用于折叠床架的腿部结构,其中金属片腿通常被容纳在角铁端轨的范围内,并且固定到端轨的内表面。 腿部的上部支撑在底座的端部导轨的水平构件上用于附加支撑。 腿上的整体式突出部分向上延伸穿过终端轨道中的狭槽,并提供一个正向止动件,用于与相邻的可枢转连接的侧轨道接合,以限定端部和侧部轨道之间的直角位置。
