A rack for a truck bed includes a structural framework formed by a set of linear rails and a set of couplings. Each linear rail has a first end connected to one of the couplings and a second end connected to another of the couplings, wherein the rails and the couplings are connected to form a driver side frame, a front frame, a passenger side frame, a rear frame and a top frame. Each rail has a uniform cross-sectional profile including an outer profile that forms an outwardly directed T-slot and a central tube having an interior profile that is a complex shape. Each coupling includes a rigid body and a plurality of linear connectors extending from the rigid body, wherein each linear connector has an exterior profile that is a complement to the interior profile of the rail to which the connector is connected.

An inflatable topper structure for a pickup truck bed is provided. The inflatable topper structure includes an inflatable topper body and a side bar structure for fixing the inflatable topper body to a pickup truck bed, where the side bar structure includes a first side bar and a second side bar; the first side bar is connected in a matched manner between a right side wall of the inflatable topper body and the pickup truck bed; the second side bar is connected in a matched manner between a left side wall of the inflatable topper body and the pickup truck bed; the first side bar and the second side bar are symmetrically arranged and each fixedly locked to the pickup truck bed; a top of each of the first side bar and the second side bar is provided with a groove.

A tarpaulin system for an open cargo hold. The tarpaulin system includes a tarpaulin, a plurality of bows, a plurality of connectors, a cable, and a tail end system. The plurality of connectors connects the plurality of bows to the cable while the tarpaulin is draped atop the plurality of bows. The tarpaulin bracket system allows for quick, and easy, replacement, or fixing, of the plurality of connectors or damaged bows allowing for much easier and efficient replacement while traveling in harsh environments.

The invention relates to a method of attaching a wire mesh sunshield screen to a building in which the screen is connected to the building by at least one traction element (119, 120, 121) and the screen is tensioned by exerting a traction on the traction element. The traction on the traction element is provided by a compression spring (30) and the intensity of the traction on the traction element is evaluated by an evaluation device (500, 501, 1550) comprising an opaque mask (1550) and a movable visual indicator (500, 501) which is movable relative to the opaque mask (550) as a function of the compression of the spring (30).
