摘要： An apparatus for transporting and supporting fire fighting ventilation equipment is disclosed. A fan support frame supports one or more ventilation fans thereon. Extending in an upward direction from the fan support frame are a pair of arms whose length may be adjusted. Pivotally attached to each arm near its upward end is a rearwardly extending leg. The length of each of the rearwardly extending legs may be individually adjusted. An adjustable length bracket is provided for each leg and arm combination to hold the two components apart at the desired angular distance. An extendable leg is also provided at the front of the fan support frame. Wheels are provided on the fan support frame so that one or more ventilation fans may be transported by an individual and the fans may be aimed at any angle of inclination by extending the legs so that they contact the surface underlying the apparatus.
摘要翻译：公开了一种用于运输和配置消防通风设备的设备。风扇支撑框架在其上支撑一个或多个通风扇。从风扇支撑框架向上延伸的是一对臂，其长度可以被调节。在其向上端附近枢转地附接到每个臂是向后延伸的腿。每个向后延伸的腿的长度可以单独调整。为每个腿和臂组合提供可调节的长度支架，以将两个部件保持在期望的角距离处。在风扇支撑框架的前部还设置有可延伸腿。车轮设置在风扇支撑框架上，使得一个或多个通风扇可以由个体运输，并且风扇可以通过延伸腿使其接触设备下方的表面而瞄准任何倾斜角度。

摘要： Bipod mortar stand, having one support mechanism and one lifting mechanism, is disclosed. The support mechanism has two legs forming a bipod. Each leg is pivoted at one end to a bracket fastened to a central leg. Each leg has drive stops on the other end. A connecting rod connects each leg to an open ring mounted on the central leg. The ring moves up and down on the central leg and can be fastened on the central leg.The lifting mechanism is formed by the central leg and telescoping tubes and an interior tube is integral to a locknut and an exterior tube is integral to the mortar holding structure. An intermediate tube is capable of linear movement with respect to the other two tubes. A lifting device, mounted on the intermediate tube has conic gears, one conic gear is activated from an exterior crank and the other is integral to a shank which moves with the gear box and the intermediate tube. Anti-rocking guides are arranged on the exterior tube, the intermediate tube and the shank.The lifting mechanism raises and lowers the shaft with respect to the bipod stand, in such a way that the relative position between both always remains constant.
摘要翻译：公开了具有一个支撑机构和一个提升机构的双头砂浆架。支撑机构有两条腿形成双脚架。每条腿在一端枢转到固定在中心腿上的支架。每条腿在另一端有驱动器挡块。连接杆将每个腿连接到安装在中心腿上的开环。环在中心腿上上下移动，可以固定在中心腿上。提升机构由中心腿和伸缩管形成，内部管与锁紧螺母成一体，外部管与砂浆保持结构是一体的。中间管能够相对于其他两个管线线性运动。安装在中间管上的提升装置具有锥齿轮，一个锥齿轮从外部曲柄启动，另一个与一个与齿轮箱和中间管一起移动的柄形成一体。防摇导轨布置在外管，中间管和柄上。提升机构相对于双脚架架升高和降低轴，使得两者之间的相对位置总是保持恒定。

摘要： A boom assembly has an upright stand with a vertical hollow post and on top of which is mounted an elongated hollow boom adjustable in orientation in both vertical and horizontal directions. A linear extention member for the boom is also in the form of a hollow tube. The stand includes a plurality of legs each in the form of a hollow tube and there are a plurality of foot elements such as casters. The different parts of the assembly are secured together by couplings that preferably are the same in each case. Such couplings include a hollow body with an exterior surface of a size and shape to be inserted within an adjacent hollow tube. A pair of laterally-opposite slots continue longitudinally inward from one end of the body. A lateral spreader is of a size and shape to be located within that one end of the body. A lever has one end portion inserted within the spreader to effect spreading thereof upon lateral deflection of the other end of the lever. Carried by the body are adjustable means located inwardly of the open end portion of the body for laterally deflecting the other end of the lever.
摘要翻译：起重臂组件具有带有垂直中空柱的直立支架，并且其顶部安装有可在垂直和水平方向上定向调节的细长空心吊杆。用于悬臂的线性延伸构件也是中空管的形式。支架包括多个以中空管的形式的腿，并且有多个脚元件，例如脚轮。组件的不同部件通过优选地在每种情况下相同的联接件固定在一起。这种联接器包括具有尺寸和形状的外表面的空心体，以插入相邻的中空管内。一对横向相对的狭槽从身体的一端纵向向内延伸。横向吊具的尺寸和形状要位于身体的一端。杠杆具有插入扩展器内的一个端部，以在杠杆的另一端的侧向偏转时实现其扩展。由身体携带的是可调节的装置，位于身体的开口端部的内侧，用于横向偏转杆的另一端。
