  • Publication number: 20070089216
    Abstract: A combined welding helmet apparatus is provided. The apparatus allows for several features to be incorporated into a single helmet. Particularly, several face and eye protection elements are incorporated into a single helmet. An integrated internal mechanism allows for selected elements to be functionally positioned while non-selected elements are unobtrusively positioned to a non-functional position. At least three face and eye protection elements are combined in the helmet; a dark filtered welding lens, a lighter filtered lens, and a clear safety plate.

  • Publication number: 20050067849
    Abstract: A pickup truck modification wherein the truck bed is effectively extended laterally by providing opposing, hingedly attached sidewalls. The sidewalls may be selectively positioned vertically or horizontally, and, when positioned horizontally, allow for positioning relatively wide loads. The truck bed is effectively widened as the sidewalls are laterally positioned in weight bearing relation by abutment members which depend from the sidewalls. Loads wider than the truck bed, but not substantially exceeding the additional width created by the laterally extended sidewalls, may be placed on the truck bed with the excess portion of the load supported by the sidewalls. When used in combination with an extendable ramp assembly, loading and unloading of bulky loads is greatly facilitated.
