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： A room service table includes a frame, a tabletop including folding side portions and wheels. A push handle assembly mounts to an underside of the table and includes a handle portion and a hinge body portion. The handle portion includes a grip, a support portion and a hinge pin portion. The hinge body mounts to the tabletop and includes barrel portions supporting the hinge pin portion. The hinge pin portion has a tab formed in an end thereof engaging a complementary slot formed in the hinge body portion. The slot includes a first section and a second section that receive and retain the tab for aligning and securing the handle at the use position and at the storage position. The biasing member urges the pin toward the slot. Rotation is accomplished by sliding the handle axially so that the tab disengages the slot and rotating the handle to the desired position and then releasing the handle.
摘要翻译：客房服务台包括一个框架，一个桌面，包括折叠侧面部分和轮子。推把组件安装在桌子的下侧，并且包括手柄部分和铰链主体部分。把手部分包括把手，支撑部分和铰链销部分。铰链主体安装在桌面上并且包括支撑铰链销部分的筒部。铰链销部分具有接合形成在铰链主体部分中的互补槽的端部中的突片。所述槽包括第一部分和第二部分，所述第一部分和第二部分接收并保持所述突出部，用于在所述使用位置和所述存储位置处对准和固定所述手柄。偏置构件将销朝向槽推动。旋转是通过使手柄轴向滑动来实现的，使得突片脱离槽并将手柄旋转到期望的位置，然后释放手柄。

摘要： An elevationally adjustable folding stage (20) includes stages decks (22) on a folding frame (24). Telescoping legs (26) extend from the frame (24) and include a spacer assembly (80). A spacer member (84) is engaged by a spreader member (82) to adjust the width of the spacer assembly (80). Rotatable wheels (88) are mounted on the spacer member (84) to engage the inner portion of an outer leg member of the telescoping legs (26). A spacing linkage (30) includes linkage members (52) and (54) with a stop member (58) mounted on the first linkage member (52) and engaging the top of the second spacing linkage (54). Stop member (58) is adjustably mounted to change the engagement point and the folding range of the folding linkage (28) and therefore, the alignment of the stage (20).
摘要翻译：可升降折叠台（20）包括在折叠框架（24）上的台甲板（22）。伸缩腿（26）从框架（24）延伸并且包括间隔件组件（80）。间隔构件（84）由扩展构件（82）接合以调节间隔件组件（80）的宽度。可旋转轮（88）安装在间隔件（84）上以与伸缩腿（26）的外腿构件的内部接合。间隔联动装置（30）包括具有安装在第一联动构件（52）上并与第二间隔连杆（54）的顶部接合的止动构件（58）的连杆构件（52）和（54）。止动构件（58）可调节地安装以改变折叠连杆（28）的接合点和折叠范围，并因此改变台架（20）的对准。

摘要： A stage or other structure having support legs includes rollers which are mounted so as to be supporting the stage in a first position and having the stage legs support the stage in a second position. A lift mechanism includes actuating pedals near the ground for raising and lowering the assembly. A linkage pivots the roller mounting member between a raised and lowered position relative to a cross member on the frame. A second pedal is selectively engageable by a single foot for retaining the roller assembly in either the raised or lowered positions.

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 of interchangeable widths 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。可互换宽度的舞台面板形成舞台表面，并且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。
