The flange has an impact surface that extends perpendicular to the contact surface and rests against the wall of the channel. The flange has a snap-in edge that engages below and can be released from the head of another wall having a T-shaped cross-section and being positioned opposite the first wall. Positioners enclosing at least partly the inserted area of the snap-in edge of the foot-section flange, are inserted into a longitudinal snap-in groove. The positioners have resilient tongues above the snap-in edge resting against the head of the T-section wall.

Abstract: A portable and temporarily installable vehicle cover is supported by a frame, which in turn is supported by brackets attached to the vehicle rocker panels or floor pan. Alternatively the brackets may be secured to stakes which are secured in the ground near the midpoint of each side of the vehicle. The frame is formed of a forward, central and rear support. Each end of the forward support is secured to the brackets, while each end of the rear support is secured to the corresponding ends of the front support.
