A restraint assembly includes a lateral restraint comprising a guide face, wherein the lateral restraint is configured to be rotatably coupled to a tray of the cargo system. The restraint assembly also includes a vertical restraint rotatably coupled to the lateral restraint. The restraint assembly is configured to have a stored position and a raised position. In the stored position, both the lateral restraint and the vertical restraint are configured to be disposed within a volume defined by the tray of the cargo system. In the raised position, the vertical restraint and at least the guide face of the lateral restraint are configured to be disposed above the volume defined by the tray of the cargo system such that the restraint assembly provides at least one of longitudinal guidance, lateral restraint, and vertical restraint to cargo.

Some embodiments of the technology disclosed herein relate to a sensor device. An elongate sleeve has a first end and a second end and extends along a longitudinal axis. A plurality of sensors are fixed relative to the sleeve. A first endcap is coupled to the first end, where the first endcap has an endcap body. A first axle is coupled to the endcap body, where the first axle extends along the longitudinal axis and the first axle defines a retaining feature. An intermediate component is coupled to the first axle, and the intermediate component is selectively rotatable about the longitudinal axis. The sensor device has an orientation locking structure that is configured to be engaged to selectively fix the orientation of the intermediate component about the longitudinal axis relative to the endcap body.

A finger guard member includes: a first surface disposed between one end of a roller and a belt wound around the one end; a second surface in which a notch having a width larger than a shaft diameter of a fixed shaft of the roller is formed with respect to the fixed shaft positioned outside the one end in a longitudinal direction of the roller; and a positioning part disposed inside the notch. When the fixed shaft has a first shaft diameter, the finger guard member is positioned by the positioning part being supported by a peripheral surface of the fixed shaft. When the fixed shaft has a second shaft diameter greater than the first shaft diameter, the finger guard member is positioned by an edge of the notch being supported by the peripheral surface of the fixed shaft with the positioning part being not present on the second surface.

The invention is a gap accessary device for elevated roller rails disposed on a platform floor. The device includes a housing, fingers, tangs, roller support structures, rollers, a first curved truncated inclined plane, and a second curved truncated inclined plane. The device allows cargo to enter a platform without catching on the platform threshold and requires less effort to load cargo onto a platform with elevated roller rails.
