Abstract: A vehicle mounted tent system includes a vehicle mounting frame for securement to the box of a pickup truck. A clamshell frame assembly having a rigid bed platform and a plurality of U-shaped support rods is connected to the mounting frame. The clamshell frame assembly including a tensioning system and functioning to transition between an open and closed position. A plurality of rigid panels is connected to the vehicle mounting frame and a tent is connected to the clamshell frame assembly. In the open position, the bed platform is positioned forward of the vehicle mounting frame, and the tent is held in an expanded position by each of the plurality of U-shaped support rods. In the closed position, the bed platform is positioned directly above the vehicle mounting frame, and the tent is positioned within a space defined by the plurality of rigid panels.

Abstract: Improved fatigue strength properties are achieved in an induction hardened microalloy steel useful for demanding service environments. The microalloy steel has low carbon and sulfur contents, comprising in % by weight, 0.15% to 0.45% C, 0.50% to 1.60% Mn, up to 0.20% V, 0.0001% to 0.01% S, balance Fe. The material is fabricated to a selected configuration, such as an engine crankshaft, for example. Selected surfaces of the fabricated article are hardened by induction heating. The article can be used directly after induction hardening or it may be tempered at low to moderate temperatures of from about 100.degree. C. (200.degree. F.) to 290.degree. C. (550.degree. F.) to achieve a desired surface hardness and compressive residual stress level. The controlled alloy chemistry and low tempering temperature provide a substantial increase in bending fatigue strength over conventional higher carbon grade steels.
