Abstract: A hollow panel structure applicable as a wall partition, divider member and the like, constituted of a plurality of channel-shaped elements arranged in two parallel spaced rows having their flanges facing each other. The rows of elements are interconnected into a rigid, box-like structure through the intermediary of transverse spacer elements extending between the adjacent flanges of adjoining channel-shaped elements. The method of construction for the panel structure employs spot welds for interconnecting the channel-shaped elements and the spacer elements to facilitate ready removal and replacement of individual channel-shaped elements.
Abstract translation: 适用作壁隔板，分隔构件等的中空板结构由多个通道形元件构成，该多个通道形元件以彼此相对的凸缘彼此平行隔开排成一列。 通过相邻通道形元件的相邻凸缘之间延伸的横向间隔元件的中间，这些元件行被连接成刚性的盒状结构。 面板结构的构造方法采用点焊来互连通道形元件和间隔元件，以便于各个通道形元件的准备移除和更换。

Abstract: A vehicular delivery ramp apparatus includes a cargo restraint device which is elevatable above the surface thereof into a position to prevent rolling or sliding motion of cargo deposited thereon. The cargo restraint device is a gate or planar bar vertically displaceable within a transverse slit formed in the deck portion of the ramp. The restraint device is controllably interengaged in operative relationship with an elevation structure for the ramp in order to provide fail-safe operation insuring that the restraint device is exposed to afford limitation or restraint of cargo movement.
Abstract translation: 车辆输送斜坡装置包括货物约束装置，其可在其表面上升高到防止其上沉积的货物的滚动或滑动运动的位置。 货物约束装置是在形成在斜坡的甲板部分中的横向狭缝内垂直移位的门或平面杆。 约束装置与斜坡的高度结构可操作地相互接合，以提供故障安全操作，确保约束装置暴露于限制或限制货物运动。

Abstract: A transport vehicle providing a lightweight and flexible design for a medium-sized route delivery truck. The vehicle is constructed on a conventional truck chassis, and includes a plurality of cargo bays extending transversely across its width, with each cargo bay being dividable into left and right lateral half portions via a removable central panel. In at least one bay the floor in each lateral half is positionable either horizontally or slightly inclined towards the center of the truck, with the proper position being dependent upon the type of merchandise being transported in the cargo bay. The truck frame includes a pair of I beams extending longitudinally from front to rear thereof along the truck roof on top of all of the cargo bays. The pair of I beams extend in a cantilever fashion over the most rearward cargo bay, and provide the load-carrying capacity for that rearward bay by suspending the weight thereof from the pair of I beams. The vehicle design provides an exceptionally versatile delivery truck, with the removability of the central partition in each cargo bay and the adjustability of the position of the floor allowing substantial versatility as to the type of cargo capable of being carried therein. The design provides the potential of being changed on a daily basis to accommodate different types of cargo loads.
Abstract translation: 运输车辆为中型路线货车提供轻便灵活的设计。 车辆构造在常规的卡车底盘上，并且包括跨越其宽度横向延伸的多个货舱，每个货舱可经由可移除的中心板分成左侧和右侧两部分。 在至少一个海湾中，每个侧面半部的地板可以水平地或朝向卡车的中心略微倾斜，适当的位置取决于在货舱运输的商品的类型。 卡车框架包括沿着所有货舱顶部的卡车车顶从前向后纵向延伸的一对I梁。 一对I型梁以悬臂方式延伸穿过最后方的货舱，并通过将其重量从一对I型梁悬挂起来为该后隔舱提供承载能力。 车辆设计提供了一个非常通用的运输卡车，每个货舱中的中央隔板的可拆卸性以及地板位置的可调性，使得能够承载在其中的货物类型具有多功能性。 该设计提供了每天更换以适应不同类型的货物负载的潜力。

Abstract: A locking device for one or more overhead doors including a system of operatively interconnected levers adapted to be manually manipulated for imparting a closing force to the doors. The levers include a biasing member which will impart a locking force to the closed doors so as to maintain these in a fully closed and locked condition. The locking device is adapted to effect the simultaneous locking of a plurality of doors in a compartmented transport vehicle.
Abstract translation: 一种用于一个或多个架空门的锁定装置，包括适于手动操纵的可操作地连接的操纵杆的系统，以向门施加闭合力。 杠杆包括偏置构件，其将向闭合的门施加锁定力，以将它们保持在完全关闭和锁定状态。 锁定装置适于实现多个门同时锁定在分隔的运输车辆中。
