Abstract: A combined stepladder and work platform assembly is provided. The assembly comprises a top frame having two side rails and footplate, a back frame pivotally attached to the back side of the top frame and having two side rails, and a front frame pivotally attached to the front side of the top frame and having two side rails. Link bars are provided so that they maintain steps horizontal together with the side rails of the front frame. Four braces secure the back frame and front frame with the top frame at a certain angle when the assembly is used as a work platform. The front frame, the top frame and the back frame form a triangular shape while the back frame is parallel to the floor when the assembly is used as a stepladder.

Abstract: Self-locking bi-foldable load bearing segments are disclosed that can be used in applications such as ladders or ramp. First and second sections of the segment are foldably coupled to transition between an open configuration and a folded configuration. The first and second sections can include rungs pivotally attached to rails that can be further transitioned from the folded configuration to a collapsed configuration, but not transitioned from the open configuration to the collapsed configuration. Openings in the side walls of the rails allow the rungs to pivot in one direction, but not an opposite direction. In the open configuration, the openings of the first and second sections may be oriented opposite, and the direction of allowed rotation of the rungs of the first section and second section are opposite, restricting compression of the rails together. In the folded configuration, the openings of the first and second sections can be oriented the same to allow rotation of the rungs and compression of the rails together.
Abstract translation: 公开了可用于诸如梯子或坡道的应用中的自锁双折叠承重节段。 该段的第一和第二部分可折叠地耦合到打开构型和折叠构型之间的过渡。 第一和第二部分可以包括可枢转地连接到轨道的梯级，其可以进一步从折叠构型转变为折叠构型，但是不从开启构型转换到折叠构型。 轨道侧壁上的开口允许梯级在一个方向上枢转，但不是相反的方向。 在打开构造中，第一部分和第二部分的开口可以相对定向，并且第一部分和第二部分的梯级允许的旋转方向相反，限制了轨道的压缩在一起。 在折叠构造中，第一和第二部分的开口可以被定向成相同，以允许梯级的旋转和轨道的压缩在一起。
