    • A combination portable dolly and tool box which includes a generally rectangular main body forming a storage area confined between front and rear side walls, opposing end walls, a bottom wall carried by a pair of wheels and a top wall forming both a lid and a load support surface. The top wall is configured to provide an inclined load surface which cooperated with a removably mounted vertically extending frame to allow relatively large construction panels, such as dry wall of the like to be transported in a vertically stacked on-edge relationship in a manner commonly associated with the widely known “dry wall dolly”. The vertical frame may be removed and may be stored in a releasably fixed position within the storage area of the main body which also accommodates for the storage of tools and accessory items commonly used. Further, a handle is provided on one end of the main body to allow the main body to be raised on one end for rolling transport on an opposing set of wheels as a whole for travel from one site to another.
    • 一种组合便携式小车和工具箱,其包括大致矩形的主体,形成限制在前后侧壁之间的存储区域,相对的端壁,由一对车轮承载的底壁和形成盖和负载的顶壁 支撑面。 顶壁被构造成提供倾斜的载荷表面,该倾斜的载荷表面与可拆卸地安装的垂直延伸的框架配合,以允许相对较大的构造板,例如其中的干壁以垂直堆叠的边缘关系以通常相关联的方式输送 与众所周知的“干墙小车”。 垂直框架可以被移除并且可以被存储在主体的存储区域中的可释放地固定的位置中,该位置也适于存储通常使用的工具和附件。 此外,在本体的一端设置有把手,以允许主体在一端上升起,用于在相对的一组车轮上整体滚动运输,以便从一个位置移动到另一个位置。

    • A durable medical equipment transport system having a frame with a top and a bottom. Attached to the bottom of the frame is a foot having a top and bottom surface and an axle having two wheels. Attached to the top of the frame are two arms which are adjustable between a folded position generally parallel to the frame and an extended position generally normal to the frame. The invention further has a pair of extension forks attached to the bottom of the frame. The extension forks are adjustable between a folded position generally parallel to the frame and an extended position generally normal to the frame. The invention further has a C shaped bracket attached to the top surface of the foot.
    • 一种耐用的医疗设备运输系统,具有顶部和底部的框架。 附着在框架底部的是具有顶面和底面以及具有两个轮子的轴的脚。 连接到框架的顶部的是两个臂,其可在大体上平行于框架的折叠位置和大体上垂直于框架的延伸位置之间调节。 本发明还具有一对附接到框架的底部的延伸叉。 延伸叉可在大体平行于框架的折叠位置与大致垂直于框架的伸出位置之间调节。 本发明还具有附接到脚的顶表面的C形支架。
