Abstract: An agility ladder includes a plurality of rungs, a left link assembly disposed between each rung and including ends pivotally attached to left ends of each rung, a right link assembly disposed between each rung and including ends pivotally attached to right ends of each rung, and first and second links included on each of the left and right link assemblies. The first and second links may be pivotally attached at a link pivot joint, where, through pivotal attachment of the left and right link assemblies with the plurality of rungs and pivotal attachment of the first and second links, the plurality of rungs are moveable from an open position where the plurality of rungs are spaced apart from one another to a collapsed position where the plurality of rungs are aligned adjacent to one another and are not overlapping with one another.

Abstract: A multiple functional, foldable, and portable ladder comprises a plurality of ladder units 5, wherein the ladder unit has a supporting rod on the two sides thereof. Each supporting rod is foldable so that the ladder is expandable for upstanding or foldable so as to be carried and stored and be used in emergency. Thus the ladder is convenient in application and storage. Two supporting rods between two adjacent ladder units 5 are pivotally connected by pivotal shafts, and two ends of each pedal are installed with respective control seats. A pivotal shaft and a movable buckling rod are installed within the control seat. Thereby, when the ladder is expanded, the supporting rod of the ladder unit is assembled by the control seat, during folding, the supporting rods are folded after the buckling rods has been displaced.
Abstract translation: 多功能，可折叠和便携式梯子包括多个梯形单元5，其中梯形单元在其两侧具有支撑杆。 每个支撑杆是可折叠的，使得梯子可扩展以用于直立或可折叠，以便携带和存储并在紧急情况下使用。 因此梯子在应用和存储方便。 两个相邻的梯子单元5之间的两个支撑杆通过枢轴枢转地连接，并且每个踏板的两端安装有相应的控制座。 控制座内安装有转动轴和可动弯曲杆。 因此，当梯子膨胀时，梯子单元的支撑杆通过控制座组装，在折叠期间，在屈曲杆已经移位之后，支撑杆被折叠。

Abstract: A frame assembly supports a work surface of either flexible material or of sections of foldable and unfoldable relatively rigid material all so that the frame assembly and material may either be unfoldable and rigidized or folded into a compact package. The flexible frame assembly includes a pair of spaced poles and a number of hinged sections aligned so that the poles and material can be folded in sections. The poles rotate to permit either a frame folded disposition or a frame rigidized disposition. Embodiments include stretchers, screens and enclosures. The rigid material assembly provides a collapsible and rigidizable space spanning structure formed with a number of hinged sections of center supports and plates hingedly connected together to be either folded into a relatively compact device or unfolded and hingedly positioned to form rigidized space spanning structures.
