摘要： A leveling system for a containment unit is disclosed. This leveling system includes at least one and typically multiple leveling elements, each of which are adjustably attached to a surface of the containment unit. An adjustment mechanism is in communication with the leveling elements for displacing the leveling element or elements in a substantially vertical direction. The leveling system also includes a level measurement mechanism attached to a surface of the containment unit for indicating a containment unit horizontal planar position or indicating when the containment unit is nulllevel.null A containment unit is also disclosed.
摘要翻译：公开了一种用于容纳单元的调平系统。该调平系统包括至少一个并且典型地多个调平元件，每个调平元件可调节地附接到容纳单元的表面。调节机构与调平元件连通，用于使大致垂直方向上的调平元件移位。流平系统还包括附着到容纳单元的表面的水平测量机构，用于指示容纳单元水平平面位置或指示何时该容纳单元是“水平”。还公开了一种收容单元。

摘要： An improved retractable roller mechanism 20 and method for statically supporting an item 42 upon a support surface 40 in an inoperative state and supporting the item 42 to roll along the support surface 40 in an operative state. The retractable roller mechanism 20 includes a housing 22, a roller frame 24 that is slideably engaged with the housing 22, a spring 30, and a roller 28. The roller frame 24 has reciprocative movement relative to the housing 22, such that the frame 24 has an inoperative position state where the frame 24 is retracted allowing the housing 22 to rest on and statically contact the support surface 40 and an operative position state where the frame 24 is extended such that the housing 22 is not in contact with the support surface 40 allowing the item 42 to roll along the support surface 40.
摘要翻译：一种改进的可缩回辊机构20和用于在处于非工作状态的支撑表面40上静态支撑物品42并且支撑物品42在操作状态下沿着支撑表面40滚动的方法。可伸缩辊机构20包括壳体22，与壳体22可滑动地接合的辊框架24，弹簧30和辊28.辊框架24相对于壳体22具有往复运动，使得框架24 具有不工作位置状态，其中框架24缩回，允许壳体22搁置并静止地接触支撑表面40以及框架24延伸的操作位置状态，使得壳体22不与支撑表面40接触允许物品42沿着支撑表面40滚动。
