Patents by Inventor Heinz-Andreas Kellner

Heinz-Andreas Kellner 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: 5897225
    Abstract: A watertight photographic single-use camera having a first and a second body shell that join together. The body shells comprise rigid polymer material and are adapted to receive a film transport device, a lens, a flash unit and a viewfinder. The first body shell forms the camera front section and the second body shell forms the camera rear section. A sealing means comprising an elastic polymer material is attached to an edge of at least one body shell that forms a joint and to at least one edge that forms a body opening. The elastic polymer material is attached by a multiple-component injection molding process and is connected to the body shell by chain looping (molecular entanglement) of the polymer material. As a result, the camera is dependably sealed against water and yet is inexpensive and simple to produce.

  • Patent number: 5832312
    Abstract: A watertight body for accommodating a photographic camera. The body has a first and a second body shell of rigid polymer material that can be joined together for accommodating a photographic camera. The body has sealing means comprising elastic polymer material provided by a multiple-component injection molding process on an edge of at least one body shell that forms the joint and on surface areas of the body shells. The elastic polymer material is connected to the body shell by chain looping (molecular entanglement) of the polymer materials. The result is that the body is reliably sealed against water and is nevertheless inexpensive and simple to manufacture. For a simple and correspondingly inexpensive recyclability of the body, the body shells can be crushed without separation of the polymer materials using known devices, with the resultant material mix being usable as an admixture for the manufacture of new camera components.
