Patents by Inventor Robert Dernovsek

Robert Dernovsek has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8439411
    Abstract: The present invention is directed to an energy absorbing component externally mounted to a vehicle having a beam structural member and at least one energy absorber operably connected to the beam structural member. The energy absorber absorbs energy when the vehicle undergoes a collision. Also included is a beam cover plate connected to the beam structural member through the use of resistive implant welding, which simplifies the manufacturing process, and improves manufacturing costs. There are two vehicle attachment plates which are overmolded to the beam cover plate, the vehicle attachment plates allow for the beam cover plate to be attached to a vehicle. The beam cover plate, beam structural member, and energy absorber form a component that is operable to function as a bumper that is connected to a vehicle, which absorbs energy during a collision.

  • Patent number: 7976298
    Abstract: The invention provides an article, a method and an apparatus of forming expanded plastic materials in a steam chest mold having out of die draw features. This is achieved by means of a cavity pull system. The cavity pull system allows for the provision of molded features outside the die draw and is designed to operate on a cam type system using two stainless steel rods running at a right angle to one another. A gear mechanism allows molded features, e.g. holes, to be formed at any angle on any part design where enough part geometry exists to accommodate the forming features and in the tool for mechanism components. The invention is advantageously employed in the formation of holes outside the die draw in vertically stacked injection tools for energy absorbers used in vehicle bumper fascias. The provision of out of die draw molded features is useful for fascia component locating or attachment.

  • Publication number: 20080272510
    Abstract: A traditional steam chest molding apparatus for the manufacture of products from expanded plastic materials requires excessive amounts of steam to properly expand and fuse pellets of plastic together A molding apparatus is provided wherein a pair of complementary molds (100, 300) are provided with a steam manifold (110) to introduce steam into the mold cavity by way of steam lines (160, 162, 164, 166) The steam manifold (110) allows for direct injection of steam into the manifold and hence a reduction in the total steam required for a molding operation The amount of steam necessary for the production of a particular article is predetermined in dependence upon a geometry and a size of the article to be produced Thus if desired, the amount of steam provided to the mold cavity is measured prior to injection
