Abstract: A retractable overhead guard assembly is provided to protect an operator of industrial trucks, such as a forklift operator, from falling objects. Said guard is retractable from a raised to a lowered position for operation in areas of low overhead clearance. A pair of substantially parallel extensible supports are attached to said truck. A guard is mounted on the upper ends of the supports and is manually slideable between a forward and rearward position and is maintained in either position by a locking mechanism. Said supports may include biasing means such as springs to counterbalance the weight of the guard and facilitate manual adjustment between raised and lowered positions. A locking mechanism is also provided on each support to retain the guard in a plurality of positions. Electrical interlocks prevent the raising of the lift beyond a predetermined height if the guard is not in the rearward and raised position where it offers maximum protection to the operator.

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.
