    • A table with a movable working surface is supported on a table frame with legs. A running rail arrangement is provided on the table frame and cooperates in a form fitting relationship with a pair of edge rails extending from the working surface. The running rail arrangement is divided into two running rail elements. A first running rail element is rigidly fixed to the table frame. A second running rail element is rotatably mounted to the table frame at a location adjacent to the first running rail element. The first running rail element has a sloped bearing surface on which the second running rail element is supported when the working surface is in a horizontal position. Each edge rail includes a holding and sliding element for supporting the second rail running element. During usage of the work surface, the holding and sliding element is located either under the first running rail element or is supported on the sloped bearing surface of the first running rail element.
    • 带有活动工作面的桌子支撑在带有腿部的桌面上。 行走轨道装置设置在桌子框架上,与从工作表面延伸的一对边缘轨道形成配合关系。 行驶轨道装置分为两个行驶轨道元件。 第一行驶轨道元件刚性地固定在桌子框架上。 第二行驶轨道元件在与第一行驶轨道元件相邻的位置处可旋转地安装到台架。 第一行进轨道元件具有倾斜的支承表面,当工作表面处于水平位置时,第二行进轨道元件被支撑在该倾斜的支承表面上。 每个边缘轨道包括用于支撑第二轨道运行元件的保持和滑动元件。 在使用工作表面期间,保持滑动元件位于第一行驶轨道元件的下方或者被支撑在第一行驶轨道元件的倾斜支承表面上。

    • An apparatus for displacing a line of track chain is disclosed which is employable for the purpose of disassembling, assembling, or reassembling the chain. A guide table for guiding movement of the chain is adapted to tilt only in the upward direction together with a pair of rails which are raised or lowered by actuating a first cylinder. A trolley moves forward and backward in the space as defined by both the rails by actuating a second cylinder while it is guided along the rails. The trolley is provided with an engagement rod which extends upwardly therefrom through a slot on the guide table to come in engagement to a bushing in the chain. Forward displacing of the chain is achieved by way of the steps of tilting up the guide table together with the rails by actuating the first cylinder, displacing the trolley forward by a distance equal to one pitch of the chain by actuating the first cylinder, lowering the rails to the lowermost position by retracting the first cylinder and displacing the trolley backward to the initial position by retracting the second cylinder. A distance of displacement of the chain is adjustably determined by selectively determining the position of two stoppers on a stationary screw spindle which is extended below the rails in parallel to the latter. Each of the stoppers is adapted to abut against an abutment member fixedly secured to the bottom of the trolley.
    • 公开了用于移动轨道链条的装置,其用于拆卸,组装或重新组装链条的目的。 用于引导链条运动的引导台适于仅在向上的方向上倾斜,以及通过致动第一缸而升高或降低的一对轨道。 在由两个轨道限定的空间中,小车在沿着轨道被引导的同时致动第二气缸而向前和向后移动。 手推车设置有接合杆,该接合杆从其上向上延伸穿过导向台上的槽,以与链条中的衬套接合。 通过以下步骤实现链条的向前位移:通过致动第一气缸将引导台与轨道一起向上倾斜的步骤,通过致动第一气缸将手推车向前移动等于链条的一个间距的距离, 通过缩回第一气缸并通过缩回第二气缸将推车向后移动到初始位置而导向最低位置。 通过选择性地确定固定螺杆上的两个塞子的位置可调整地确定链条的位移距离,该固定螺杆主轴平行于导轨的下方延伸。 每个止动件适于抵靠固定地固定在手推车底部的抵接件。
