摘要： An elevationally adjustable folding stage has a frame which folds from a storage position to use position. Stage panels form a stage surface and are reversibly and interchangeably mounted. Connectors insert into passages from the stage frame through the stage panels and provide quick connection without additional connector elements. The connectors rotate within the channel and compress an annular sleeve member axially, forcing the sleeve outward to engage the sides of the passage and secure the stage panel to the stage. The connectors are at or below the upper stage surface and are accessible axially from above by an actuator tool.

摘要： An elevationally adjustable folding stage folds between a use position wherein the panels are substantially planar, to a storage position wherein the panels face one another. Support legs are guided into a proper folding position by a guide plate having a surface angling relative to both the vertical and horizontal axis that provides for moving the leg into a fully extended position. A spacer assembly is utilized which includes a spreader member and a spacer member having tabs engaging the interior of an outer telescoping member. The spacer members provide better alignment and less wobble between the inner and outer members of the telescoping leg assembly.
摘要翻译：一个可升降的折叠台折叠在其中面板基本上是平面的使用位置与面板彼此面对的存放位置之间折叠。通过具有相对于垂直和水平轴线的表面倾斜的引导板将支撑腿引导到适当的折叠位置，该引导板将腿部移动到完全伸出的位置。使用间隔件组件，其包括吊架构件和具有接合外伸缩构件内部的翼片的间隔构件。隔离构件在伸缩腿组件的内部和外部构件之间提供更好的对准和更少的摆动。

摘要： An elevationally adjustable folding stage has a frame which folds along a center of the stage from a storage position to a use position. Stage panels form a stage surface and are reversible and interchangeable. The stage may also support additional panels between stages extending therefrom to form an extended stage surface. The stage has a roller assembly which lifts the stage up so that rollers engage the floor for rolling between storage and use locations. Connectors between the frame and the stage offer quick connection without additional pieces. Connectors also provide for inserting risers to raise the height of one panel of the stage relative to the other. In addition to the risers, multi-panel supporting bases may be used to support the panels extending from the edges of the stage between stages. The panels between the stages may be stored on the stage while in the use or folded position by hook members which rotate from a storage to a use position to retain the additional panels. Folding of the stage is assisted by a spring folding assist member which prevents closing of the stage and assists in the initial opening of the stage toward the folded position. Accidental folding of the stage is also prevented by a locking linkage and a spacing linkage which lock the stage in the use position to prevent accidental folding and also to maintain the stage in the use position when elevationally adjusting the stage panels.
摘要翻译：一个高度可调的折叠台具有一个框架，该框架从舞台的中心处从存放位置折叠到使用位置。舞台面板形成舞台表面，是可逆的和可互换的。舞台还可以在从其延伸的阶段之间支撑另外的面板以形成延伸的舞台表面。该台具有一个辊子组件，该组件提升了平台，使得辊子在地板之间接合以在存储和使用位置之间滚动。框架和舞台之间的连接器提供快速连接，无需额外的部件。连接器还提供插入立管以提高一个面板相对于另一个的高度。除了立管之外，可以使用多面板支撑底座来支撑从工作台之间的边缘延伸的面板。阶段之间的面板可以在使用或折叠位置时被存储在舞台上，该钩构件从存储器旋转到使用位置以保持附加面板。舞台的折叠由弹簧折叠辅助构件辅助，弹簧折叠辅助构件防止舞台的关闭并且有助于舞台朝向折叠位置的初始打开。舞台的意外折叠也可以通过锁定连杆机构和间隔连杆机构来防止，该连杆机构将台架锁定在使用位置，以防止意外折叠，并且在高度调节舞台面板时将舞台保持在使用位置。
