  • Patent number: 4900058
    Abstract: A vehicle rollguard comprising at least one member of stanchions and struts which are detachably connected. The connections include a necked-down end of one of the interconnecting members and an opening in the other interconnecting member for receiving the necked-down end. The opening in the interconnecting member can be in the sidewall or be an open end. Pairs of opposed aligned apertures in each interconnecting member form a passage for a bolt or other securement means. Securement to a vehicle includes a bracket in the form of a plate having openings for bolting to a vehicle and a pair of upstanding tabs having opposed aligned apertures. Another pair of opposed aligned apertures on the end of the rollguard member to be secured line up with the apertures in the tabs for passage of a bolt or other securement means. A disc of hard plastic overlies the plate and is disposed between the bracket and the end of the rollguard member to be secured.

  • Patent number: 4171141
    Abstract: The following specification discloses a vehicle reinforcing bar that can be used with a pickup truck body. In particular, one of the members of the bar is a U shaped member having mounting plates upon which it stands in the bed of the pickup truck. A pair of angularly oriented bracing members is attached at its ends both to the cross member of the U shaped member and to the bed or wheel wells of the truck. The bracing members are pivotally attached to the cross member of the U shaped member by means of collars. The pivotal mounting permits free rotation of the bracing members around the cross member. This allows the entire brace to be folded into a flattened configuration for shipment until it is installed in a truck. Upon installation by attachment of the free ends of the bracing members to plates on the wheel wells, the bracing members become fixed relative to the cross members, precluding further rotation.
